Wardrobe for drying clothes - different designs and their advantages and disadvantages

With increasing urban density, there is less and less space left for street drying laundry. Again, cluttering up a balcony or a bathroom in an apartment with wet linen is also not the best solution. There is a way out of this difficult situation - this is the use of a special drying cabinet.

What is a drying cabinet

Let's try to figure out how the natural drying of laundry occurs when we take it out of the washing machine and hang it on the ropes in the yard. On the one hand, the linen is heated by the sun's rays, and on the other hand, it is blown by the wind. Thus, the rate of water removal from the tissue depends on the intensity of solar radiation and on the strength of the wind.

The more intense the impact of these factors, the faster everything will dry. When we hang our things not on the street, but on a glazed balcony, the intensity of tissue dehydration decreases significantly, since there is little sunlight and no wind in an isolated space.

The oven technology combines all the advantages of natural drying with the complete absence of the characteristic disadvantages of dehydration in an isolated space.

The cabinet looks like a hybrid of household furniture and a refrigerator. In the interior space there are a certain number of shelves and hangers for clothes and shoes. It is enough to hang freshly washed clothes inside this multifunctional furniture and turn on the appropriate dehydration mode, and after 10-30 minutes things can be used.

Purpose and features

Why should you choose a cabinet for domestic use, and not a drum-type dryer or a dryer on the street and on batteries in the apartment?

Five reasons to choose a drying cabinet:

Application efficiency. Outdoor drying is good in summer and becomes unbearably long in the cold season. The cabinet always works at the same high intensity.
Silent operation. The cabinet, unlike the drum type dryer, does not make noise at all and this is very important in terms of installation in the apartment.
Gentle effect on fabric. Since there are no mechanically moving parts in the cabinet, there is no destructive effect on things.
Things don't wrinkle. Washed linen is hung on hangers and is not subjected to mechanical stress during drying. As a result, the linen removed from the closet will not look wrinkled, but ironed.
Energy saving. The design of the drying cabinet does not have energy-intensive mechanisms. Therefore, the energy consumption is lower than when using drum machines.
Compact dimensions. The drying cabinet has a compact size, so it can be installed in any room.

The principle of operation of the drying cabinet

Illustrations	Varieties of cabinets by type of heating element
	Convection type devices. The convection-type oven is supplied with heated air from the outside through inlets at the bottom. The air, rising up, takes moisture from the hung things and, already being warm and moist, is drawn out through the inlet grill at the top of the structure. Warm moist air is expelled outside through a corrugated pipe.
	Devices with an infrared emitter. In such designs, infrared emitters are installed that heat the internal volume. As a result, warm air in an isolated volume, together with moisture, comes out. The advantage of models with infrared emitters is the uniform heating of the internal volume. Heat is reflected from the floor and side walls, and therefore things dry quickly and from all sides.

Product types

Illustrations	Types of drying cabinets and their description
	Mobile (marching). These are lightweight structures, consisting of a frame, fabric sheathing and a built-in infrared heater. For sheathing, a dense heat-resistant fabric is used. Mobile cabinets are easy to carry, and therefore are used when living in rented housing or taken with you to the country.
	Household (stationary). Such equipment has an attractive design, so that it can fit into the interior of kitchens or other auxiliary premises. Equipment for ease of operation is equipped with an automatic or semi-automatic control unit for setting the optimal drying mode. Household dryers are designed for a small amount of laundry, comparable to the volume of a single load of a washing machine drum. The equipment is installed so that it is possible to connect it to an outlet or hood.
	Specialized (industrial). This equipment features a simplified utilitarian design, and the whole structure is focused on maximum performance, strength and durability. Such equipment is used in sports locker rooms, in army laundries and other places where something is constantly washed and dried in large volumes. Most industrial installations are convection-type cabinets. The choice of the principle of operation is not accidental, since the external unit with a heating element and an air blower is easy to repair and maintain and can work for a long time.

Manufacturing materials

The materials for assembling the cabinet are selected in accordance with the type and purpose of the equipment. For example, industrial models are just an all-metal box, powder-coated on the outside and inside.

In household models, the cabinet has a complex structure with good thermal insulation. Therefore, an outer and inner box is made of metal, between which there is an insulating material with a low degree of thermal conductivity. As a result, the outer surface of the equipment remains cold during operation.

All modifications of modern cabinets have a factory-made antibacterial coating of the internal volume. This is a very important point, given the fact that there is a high degree of humidity inside, which in itself implies a risk of mold.

Shapes and sizes

The standard configuration of both industrial and domestic dryers is a parallelepiped, where the side walls are narrower than the back wall and narrower than the facade. Household equipment is designed and manufactured in such a way that it can be installed complete with home furniture.

Standard dimensions for domestic installations:

Width - from 640 to 1500 mm.
Height - from 1500 to 1840 mm.
Depth - from 350 to 600 mm.

The dimensions of industrial installations depend on the brand of the manufacturer and on the specific model of equipment. What's more, with custom-made drying units, the dimensions of the equipment can be adjusted according to the needs of the customer.

Domestic and industrial dryers differ in internal content. For example, there are single-level models where clothes and shoes are located in one compartment, and there are two-level models where clothes and shoes can be placed separately. The second option is preferable, since the smells of shoes are not transferred to clothes.

The filling of drying units is the same as in a regular cabinet, that is, there are shelves, holders for hangers, over-door hooks, mesh trays, etc. The only significant difference is that the filling of the drying cabinet is made of chrome or nickel-plated metal, which is not rusts from prolonged contact with a damp cloth.

Placement rules

We take into account the possibility of removing exhaust air. We install the cabinet so that the exhaust pipe can be run into the ventilation.
We install with the ability to connect to a network of 220V. Given that the power consumption of the drying unit is at least 1 kW per hour, try not to use extension cords when connecting, but connect the cable directly to the outlet.
We place in the immediate vicinity of the washing machine. This arrangement of the drying unit will save you from having to carry wet laundry from room to room.

Nuances of choice

When choosing a drying cabinet for domestic use, pay attention to the following points:

Design. Since the equipment is purchased for domestic use, we first of all pay attention to how it will be combined with the design of other furniture and how it will fit into the interior.
Internal volume. Calculate at least approximately how many kilograms of laundry you wash at a time. Based on the average value, choose the internal volume of the unit with a small margin.
Energy consumption. We prefer models with the lowest power consumption. Excessive electricity consumption is not justified in any way, since the dryer is not a fireplace, and a heater no more powerful than 1.5 kW will be enough to heat the air to 50-80℃.
Filling. The more different accessories for a comfortable arrangement of things, the more expensive the wardrobe. But, this is just the case when it is better to pay more so as not to sacrifice comfort later.
Governing bodies. Models with manual control are cheaper, and according to experts, breakdowns in equipment with mechanical regulators happen infrequently.

How to do it yourself

Anyone can buy a drying cabinet, but how to make such a unit with your own hands? It turns out everything is very simple.

You will need a regular cabinet with a suitable internal volume. Install a heater or a central heating battery inside the wardrobe. In the upper part of the structure, you need to arrange a branch pipe for attaching to the outlet. Cover the cabinet from the inside with waterproof paint.

Summing up

Now you know how a clothes dryer works and choose the right equipment for home use. If you still have questions about your choice, ask them in the comments to this article.

Big headache - wet shoes! Under normal conditions, it dries for a long time, and you can get your feet wet in a couple of minutes. Do not stock up on dry boots. This article will describe how to deal with this problem.

Our beloved garden and well-kept garden needs attention in any weather. And restless children want to play in the garden in the summer in the rain and lie in the winter in snowdrifts! Wet clothes and wet shoes, of course, do not scare us, but how nice it is when there is a special locker for drying! It provides a place where you can not only store, but also quickly dry wet boots, jackets and hats. For such a closet, the best place is in the hallway, the size of the closet depends on the area of \u200b\u200bthe room.

Principle of operation

Drying in the closet occurs due to the injection of warm air by an electric fan. Humid air is removed from the cabinet into the box through the ventilation hole located on the top cover. The drying cabinet works with minimal energy consumption and almost no noise.

We later replaced the oil heater with a fan heater. Its temperature is not so high and the airflow is faster. Warm jets of air rise up and gradually dry damp clothes and shoes without spoiling them. And after an hour and a half things are dry.

Progress

1. To assemble the side walls, we used furniture boards. They were cut to size and cleaned up. The optimal ones were: cabinet height - 230 cm, width - 120 cm, depth - 60 cm.

2. First, the cabinet frame was assembled. Shelves were fixed along the bottom between the walls with the help of self-tapping screws and bars. Holes were drilled in the upper shelves for hoods with a diameter of 100 mm.

3. The back wall of the cabinet measuring 230 x 120 cm was made of thick plywood. At the level of 160 cm from the floor, a clothes hanger was strengthened.

4. An area for installing an oil heater was left at the bottom of the cabinet. For fire safety purposes, the walls around the heater were insulated with a sheet of galvanized iron. Shelves made of bars with through holes were installed above the heater.

5. The last stage is the installation of an air exhaust pipe. A corrugated pipe was inserted into the opening at the top of the cabinet; it removes warm, humid air. By the way, you can use a tin pipe (round or rectangular in cross section). The pipe was attached and an exhaust grill was installed., Drilled into the wall of the house

ventilation hole, from the street closed with insulation. Both from the side of the facade and in the hallway, the edges of the pipe were hidden under the skin.

6. We prepared the cabinet doors, made through holes at the bottom for air intake from the hallway. The assembled cabinet was painted with waterproof furniture varnish.

There are household appliances designed to make life more comfortable. A drying cabinet for clothes, shoes and linen belongs to such functional furniture.

If earlier this electrical appliance was used in industrial and special institutions, now it is used for domestic needs and is gaining more and more popularity among ordinary buyers. A closet is needed when you need to quickly dry a large number of things.

Features of drying cabinets

Electric drying cabinets are available in a variety of options, but they have two common features: large capacity and the ability to significantly reduce the drying time of things. Many models are equipped with a built-in timer, temperature controller, LED lighting, ionization and ventilation functions. Their indisputable advantage is fast drying at any time of the year.

The features of the devices are as follows:

safety, there is an emergency shutdown function;
the presence of ventilation;
special surface coating that protects against mold and rust;
automatic control system;
overheat protection.

Device and principle of operation

Wardrobe electrical cabinet is a chamber made of stainless steel. Inside there are shelves for clothes, shoes, hats, accessories, underwear. Heating elements are mounted in the ceiling, bottom and back wall.

For many models, the ware block is divided into 2 sections: shoe and clothes. The module with a heating element can either be attached to the device or be built into the bottom. The device consists of two parts: a compartment for things and a module with a heating element.

The principle of operation of the device is that the air flow enters the cabinet and heats up. Moisture from clothes turns into steam and is expelled outside with the help of a ventilation system. Drying time is on average 3 hours. The time can be adjusted as you wish.

What materials are made from

For the production of clothes drying cabinets, only high-quality stainless or galvanized steel is used. Products are painted with special powder paints that protect the surface from rust.

All household samples are equipped with reliable thermal insulation, so the surface of the device does not heat up during operation. Mandatory is the antibacterial coating of the inner walls of the box. This prevents mold from forming.

Dimensions

The choice of sizes is quite wide. Initially, you need to decide on the installation location of the cabinet and the volume of things that are supposed to be dried regularly. It is believed that for an ordinary apartment the most suitable dimensions are 1800 x 600 x 600 mm (height, width, depth). The weight of household cabinets should not exceed 60 kg.

The following dimensions are suitable for children's institutions: 1500 x 350 mm (height, depth). For industrial samples, the height can reach 2.2 m, width - 1.8 m and depth - 70 cm. The cabinets can accommodate 8 complete sets of overalls, shoes and sports equipment at the same time.

How are dryers different?

In the wardrobe, things are neatly hung on hangers and laid out on shelves without being subjected to mechanical stress, and the machine dries things by means of a drum.

Another significant difference is that nothing is wrinkled in the closet. Of course, drying of long outerwear should take place in a straightened form. This cannot be done in a car. Obviously, the closet is much more spacious. Clothes and shoes in it can be dried separately.

The dryer is similar in appearance and dimensions to a conventional washing machine. You can find a place for it in almost any home. Allocating an area for a closet is a more difficult task, especially in small apartments.

Types of drying cabinets

Drying cabinets for clothes differ in the type of filling and purpose.

universal;
industrial;
children's.

Universal

They are of medium size and are used both in everyday life and in various enterprises. Dry both damp and wet things. Pillows and blankets are allowed to dry.

With a large capacity, the models are quite compact and have a good selection of programs. In addition to home use, they can be used at construction sites, industrial premises, skating rinks, gyms, etc. In hotels, hospitals, tourist camps, a drying cabinet for linen and clothes is a necessary equipment.

Industrial

Are operated at all enterprises where fast drying of a large number of overalls and footwear is required. They have a large capacity. Usually they consist of 2 sections: clothing and shoe. Inside the drying chamber there are removable perforated shelves for hats, gloves, sports equipment, etc.

Such designs can be designed for 8 complete sets of wet clothes and shoes at the same time. Indispensable in any production, construction sites, drilling stations, army laundries. Most industrial dryers are convection-type dryers. The outer box has a water-repellent surface.

Baby

The permit for the use of electric drying cabinets in preschool institutions came into force in 2013. A prerequisite for such devices is full compliance with fire safety requirements, PUE (electrical installation rules) and PTE (technical operation rules).

Drying furniture purchased for a kindergarten must be protected by enclosing elements made of safe materials. Products are compact, but very roomy. The instrument control panel is placed at such a height that the child could not reach it.

The most popular model is RUBIN RShS-5D-135. Dries 5 complete sets of children's clothes and shoes.

Criterias of choice

The choice of furniture for drying clothes and clothes depends on its purpose. In addition, all electrical appliances must comply with certain rules.

When choosing, you should pay attention to the following criteria:

compliance of the device with fire safety requirements;
internal volume of the box;
energy class;
filling;
control system;
dimensions;
product kit.

Approximately calculate the number of things that you are going to place in the closet. Choose models with low power consumption.

The cost of the device will be higher if inside it is equipped with all kinds of shelves and fixtures. Automatic devices are more expensive.

In order not to make a mistake with the choice of size, you need to decide in advance on the installation location. When buying, do not forget to check the availability of all components.

Overview of popular models

Among Russian manufacturers, the following brands have proven themselves well: Rubin, Amparo, KMK ZAVOD, MPZ. Due to the optimal ratio of quality and price, they are in demand among consumers.

Most imported models are products of the ASKO company (Sweden). The products of this brand are of good quality and modern design.

The table shows a selection of the most common models on the Russian market.

Manufacturers such as KMK ZAVOD, Moscow Metal Furniture Plant and others manufacture custom-made structures according to customer measurements.

Where to place

Before installing the drying cabinet, it is necessary to consider the ventilation system. Humid air can escape into the room, which is undesirable. It is safer when it is discharged into the ventilation pipe. Special hoses and flanges are included in the package of such installations.

Furniture with forced ventilation is installed next to the hood, the vapors are discharged through the pipe into the duct. Devices with natural ventilation are equipped with a pipe through which moisture goes outside.

Condensing cabinets can be installed in any suitable place, since they do not have a fan. If the area allows, most often the appliance is mounted in hallways, corridors, bathrooms, dressing rooms.

Drying cabinet assembly video

This video shows you step by step how to assemble your own clothes drying cabinet.

Clothes dryer is the most necessary household item in our life. But it is not always possible to afford to buy a quality dryer that will last a long time. What to do in this case? Make your own dryer! There are many options. And all of them will not take much time and money to make them.

Do-it-yourself clothes dryers: manufacturing options

Here are some options for simple and compact dryers that you can make yourself.

We make a rope dryer with screws

Do you have a free corner that is not being used? If yes, then it is possible to make a compact dryer from a minimum of parts. For this we need:

Clothesline.
Wooden planks.
A set of screws with a ring.
Hacksaw.

Let's start making:

Clothes dryer ready!

Somehow, in our country house, a metal clothes dryer broke down - the folding mechanism fell apart. And, as luck would have it, that day they started a big laundry. What to do? In thought, I went outside, and then my eyes caught on the bathhouse and the outbuilding a few meters from it. A plan instantly formed in my head. I quickly ran for everything I needed: a simple rope, nails and a hammer. And got to work. On opposite walls, she nailed six nails at a certain distance from each other to the height of her height, slightly bending their hats up to make it easier to twist the rope around them. And then, in a zigzag, from one wall to another, she stretched a rope through all the carnations, pulling it so that it would not sag. And in the end, I got a neat outdoor clothes dryer in a short time.
Such a dryer can be made near the battery

Let's start making the dryer:

After fixing the wooden blocks, mark the places for future holes. The distance between them should be 10-15 cm.
Fix the wooden part of the future dryer - this will make it easier to drill holes
Drill holes with a drill.
The diameter of the drill should be slightly larger than the thickness of the rope, for easy threading
Measure the desired length of rope and cut a number equal to the number of holes on one piece of wood.
Pull the clothesline through the outermost hole, secure the end of the rope with a strong knot.
On the other side of the hole, make another knot so that later the load does not press on the rope.
Choose a strong rope - it will last longer
Do these manipulations with all the ropes.
To secure the future dryer on the balcony or to a tree, take twine. Measure the desired length and cut four pieces. Then take two pieces, connect their ends and tie them together. Fasten the opposite ends with a knot at the two extreme holes of the wood blank. You should get a triangle. Try to tie so that its sides are the same - for the stability of the structure.
It is a pleasure to use such a dryer - if necessary, it can be easily untied and removed until the next wash.
Do the same with the other piece of wood.

The clothes dryer is ready. Hang it in a place that suits you.
Finished clothes dryer

Folding dryer do it yourself

Takes up minimal space

In order to make such a dryer, you will need:

Wood blocks for the frame.
Smooth wooden sticks or thin metal rods.
A sheet of plywood for the base is a centimeter larger than the future frame.
Furniture hinges. For a large size dryer - two, for a small - one.
Folding mechanism.
Fastener set.
Fixing latch.
Roulette.
Hacksaw.

Progress:

Measure the desired length on the bars and saw off the excess.
In the bars that will be on the sides, use a drill to make non-through holes at the same distance, with a diameter slightly larger than the future slats.
Then insert rods into them.
Assemble the frame by fastening the bars with nails or self-tapping screws.
Using furniture hinges, connect the underside of the frame to the plywood base.
Attach the folding mechanisms to the sides, and the fixing lock on top of the frame.
Fix the dryer to the wall.

Dryer with battery attachments

This dryer dries quickly.

Such a dryer takes up little space - if necessary, it can easily be removed from the battery, easily disassembled and put away in a closet, for example.

To make a dryer you will need:

Polypropylene pipes.
Corners and tees.
Hacksaw.
Roulette.
Pencil.

Let's start crafting:

Use a tape measure to measure the size of the battery.
Cut the pipes for the rods according to the length of the battery. You will also need short lengths for the gaps between the rods and a little longer for attaching to the battery.
Connect the structure with corners and tees. Make fastenings to the battery at an angle of 90 about to the frame.

Wooden grating for the bath

This dryer is great for drying small items.

This is the easiest clothes dryer to make - it requires a minimum of parts and time spent on its assembly.

You will need:

Wooden slats.
Self-tapping screws.
Screwdriver.
Lacquer for wood.
Sandpaper.

Let's start assembling:

We take wooden slats and saw off the desired length, focusing on the width of the bath. You will need 6-7 rails. You will also need transverse rails, on which you will mount the longitudinal ones - 2-3 pieces, the length depending on the desired width of the dryer. All parts must be sanded to get rid of notches. Now we take short slats, we put long slats perpendicularly on top - at some distance from each other. It remains to connect the intersections with screws. For the durability of the grate, treat it with varnish.

Drying cabinet

The assembly of such a cabinet is carried out using furniture panels, its height is 220-230 cm, width 60-90 cm and depth 40-50 cm. The compartment for an oil heater or fan heater is located at the bottom and is insulated with galvanized iron or foam flora. The interior space of the cabinet is equipped with strips for clothes and shelves for shoes.
Diagram of a wardrobe for drying clothes

The device of the drying cabinet may differ solely on the basis of the specifics of the apparatus. There are household and industrial appliances; some are for drying clothes, the second - for uniforms, the third - for ski clothes and so on. There are also special apparatus for processing solvents - but we are more interested in units designed to dry clothes, and we'll talk about them.

About the purpose of the electric dryer

At enterprises, in the hotel and tourism business, as well as in kindergartens and other organizations where drying of large volumes of clothes and textiles is required, special drying cabinets are used. The size, power and functionality of this technique can vary significantly. A separate place in this area is occupied by laboratory devices that dry, heat or sterilize instruments - such devices have a complex principle of operation and, as a rule, this is not interesting for the layman.

Types of drying cabinets (SH)

Today, according to the type of device, all SSH are divided into three main types:

Vacuum.
Thermo-convection.
infrared.

And if vacuum ones are industrial units, and infrared ones are completely created for drying confectionery and other food products, then thermo-convection ones are the devices that interest us the most.

They may be as follows:

Universal. These are metal devices that can be used both in industrial and domestic environments. Inside there are shelves and hooks.
Industrial- suitable only for large productions. They have a large capacity compared to universal options.
Baby. Compact, more often household (or for kindergartens, schools) devices. They are also bought by people of short stature.

How does the machine work?

Like that:

The air inside the cabinet warms up.
Heating elements are used for heating.
Air is circulated through the chamber by fans.
Heaters and fans are located on the bottom side, on the ceiling or at the rear of the structure.

The mode, temperature, type of fabric and other parameters are selected on the control panel, which can be mechanical or electronic.
Inside there are hooks for hanging, straps for hangers, shelves and compartments for shoes and accessories.
The design can be horizontal or vertical - this does not particularly affect the scheme of work. The box itself is made of metal, and the sections and shelves are perforated with small holes to speed up the processing of things and textile materials.
Inside there is a thermostat that is responsible for heating the air when its temperature drops below the set one.

Important! When installing the apparatus, it is recommended to organize a special hood based on a corrugated pipe. If there is no possibility in organizing ventilation, you will often have to ventilate the room to avoid high humidity and the appearance of mold and fungus on surfaces.

SH dimensions

The main condition that is put forward for such a device is compliance with all safety rules, and dimensions play an important role in this. Outside, it should be compact, inside roomy - this is achieved due to the classic rectangular shape. When choosing a device, keep in mind that the higher it is, the better the air circulates and the better the moisture is removed. For an apartment, the following dimensions of the device are recommended: 60 x 60 x 180 cm. The wardrobe for children's clothes is slightly smaller: 60 x 25 x 150 cm. The width of the box depends on the number of sections. Models on the market are standardized, but some brands can order individual production.

Temperature

To prepare clothes, the temperature should be in the range of 70-80 degrees. Linen and shoes are quite delicate things; temperatures above 60 degrees are not recommended for them, otherwise the risk of damage to materials increases. If we are talking about an industrial unit, then the design has a branch pipe with a gate, which serves for exhaust ventilation. With the help of the gate, you can adjust the drying mode - it affects the temperature and the rate of supply of heated air flows.

What is inside the SC for clothes?

Usually in the school there are telescopic hangers in several sections - you can hang shirts, suits, jackets on them. In the lower compartment you can place shoes, hats, toys and more. The following can also be implemented:

Quick assembly, extension (if needed).
Compartment for accessories.
Electronic control. different modes.
Simultaneous work with different materials/fabrics.
Ionization, filtration, aromatization, etc.

Who is producing?

There are not many dryer manufacturers in our market, but some brands nevertheless "broke through" and their cabinets took a confident place among traditional drum dryers. Pay attention to the products of such Swedish companies as Asko and Electrolux, and there are also good offers from domestic brands HOTSTORM and DION.

Is it possible to do it yourself?

Want to save? Tips from home craftsmen and their carefully recorded videos will help you! To build the device yourself, you will need classic fan heaters, which are usually used for space heating.

The most difficult moment during assembly is the installation of a pipe that will draw out moist air. For this purpose, a corrugated pipe of any shape is inserted into the body - one end is adjacent to the body, the other - to the exhaust grille. A special hole is drilled in the wall, and everything is carefully isolated from the street. The pipe itself is securely sheathed. The case must be metal, and it is imperative to drill holes in the doors for air to enter. The finished device is covered with waterproof furniture varnish. Details in the video.
