Description

The utility model relates to drying devices and is intended, in particular, for drying clothes.

Currently, the world uses a convection method of drying clothes. This method is quite expensive. It is necessary to build expensive drying chambers, to pump hot air into the chambers. Hot air, in contact with the material, heats it and removes moisture. Then moist warm air is removed from the chamber.

Infrared drying can significantly simplify, speed up and reduce the cost of this process. At the same time, the quality of finished products (dried clothes) increases. No need to specifically build drying chambers. As a rule, such cameras can be moved to any convenient place. It is not necessary to heat the air and drive it between the layers of material with subsequent removal, which leads to high energy costs. The energy cost of infrared drying is 2.5 times less than with convection drying. It is possible to carry out drying in any not heated room. In the warmer months, you can dry on the street under a canopy. With infrared drying, the materials on the suspension in the chamber are heated to the entire thickness, and not superficially as with a convector. The process of moisture return occurs throughout the thickness of the material. Dryness is uniform. Clothing material does not undergo structural changes.

It is known that a drying device is made in the form of a horizontal platform with a vertical flat thermal panel located on it, having devices for hanging drying items, moreover, an infrared emitter is uniformly installed in the thermal panel, in addition, a shutdown timer is installed in the thermal panel, and legs or rotary rollers are installed on the horizontal platform , or wheels (RU 142840, publ. 07/10/2014).

The disadvantage of this solution is the complexity of the design of the frame rack, made in the form of a flat frame, on which a thermal panel is fixed, mounted on a flat large base. Since hooks for hanging clothes are fixed in the upper part of the frame, a tipping moment is formed after hanging. In this regard, the base is made heavy and developed in area so that the projection of the center of gravity of the frame with the panel and clothing passes through the supporting base, in its internal borders, and not outside. As a result, the known solution is a stationary structure with a weighting agent in the base, which does not allow it to be moved mobile from one position to another. In addition, since the clothes hang on hooks and practically lie on the thermal panel, in the known solution the thermal panel is specially fenced with a mesh casing to form an air gap between the clothing and the panel (necessary for heat flows from the thermal panel). Another disadvantage is that clothes are hung on hooks by the inner hanger on the clothes, and not on the shoulders. As a result, the clothes dry in a crumpled state (not straightened). Despite the fact that the use of infrared elements allows thermal rays to penetrate through the clothing material without hindrance, but after drying, the clothing takes on an untidy appearance and requires smoothing.

These drawbacks are partially eliminated in the drying device, which is a frame cabinet on supporting legs made of polymer and aluminum tubes connected at the points of mutual intersection through polymer clamps; a heating panel is fixed on one wall of such a frame and open from all sides of the cabinet on polymer holders with a coating of aluminum material, in the upper part of which there is an infrared emitter with a controller (CN 202730493, D06F 58/10, D06F 58/26, A47B 61/00, A61L 2/08, published 13.02.2013). This decision is made as a prototype.

By design, such a cabinet is lightweight and therefore portable or mobile. A rectangle is organized in the upper part of the frame cabinet from the tubes, in which the tube farthest from the heating panel is used as a hanger for clothes hanger. Therefore, clothes in such a cabinet hangs straightened and at a distance from the heating panel. In height, the heating panel is fixed at the level of the upper rectangle and at a distance from the support legs, which indicates that the position of the panel is determined by the position of the suspension lines of the clothes hangers in order to allow drying of short or short clothes, while ensuring a height margin for long clothes.

The disadvantage of this design is the lack of drying efficiency, due to the fact that all clothes are hung on one hang. With this arrangement of clothes, the density of hanging them increases, but this leads to the fact that parts of the clothes that are externally located on the hanger dry out faster than parts that adjoin each other. In addition, the pieces of clothing located on the side of the heating panel dry faster than the pieces of clothing on the other side hung. The unevenness of drying leads to drying out of one side of the clothing with respect to the other part. And when the clothes are discharged, that is, when they are suspended with an air gap between the individual items, the number of things to be dried is reduced. In addition, it is necessary to periodically turn over the clothes to be dried to ensure that they are evenly dried. Since the hanger is also the transverse core element of the cabinet frame, on the shoulders the upper part of the clothes is outside the coverage area of the heating panel, and this part of the clothes is dried by convective heat fluxes. Drying of hats is not provided, and for long products, the lower part of clothing (floors) is not exposed to heat, but dries naturally.

The technical result is to increase the drying efficiency of clothes due to its location in the area of the heating panel with a staggered arrangement on the hangers.

The specified technical result is achieved by the fact that in a clothes dryer containing a frame structure made of rod elements, a cabinet open on all sides and made with support on legs on a supporting surface, and a heating panel with infrared radiation located between the racks on one side of the cabinet and associated with these racks, and also hung for clothes and a heating panel control controller with a time setting function, the heating panel with infrared radiation is made with a length equal to the height of the cabinet between at the transverse rod elements connecting the racks to which the heating panel is attached, in the upper part of the cabinet above the indicated transverse rod elements connecting the racks, a grid of shelves is arranged to accommodate hats, and the cabinet is divided in height into two sections, in the top of which hung are located under the shelf from the grid, and in the bottom - at half the height of the cabinet from the legs to the specified transverse bar elements connecting the racks, while in each section you hung olneny as two horizontally spaced-apart rod elements for hanging on clothes hangers are staggered.

In addition, in the lower part between the racks, forming an open opening from the side of access to the sections of the side walls, and the racks between which the heating panel is placed, braces can be fixed with fastening elements on them for an additional inclined shelf for drying shoes.

These features are significant and are interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present utility model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the required technical result.

In FIG. 1 is a general view of a clothes drying apparatus;

FIG. 2 - demonstration of thermal radiation flux when using two opposite standing dryers;

FIG. 3 - Same as in FIG. 2, a plan view of the drying room;

FIG. 4 is a variant of the drying device of FIG. 1 with an additional shelf for shoes.

According to this utility model, the design of a drying device using IR thermal radiation for quick drying of clothes is considered.

Such a clothes dryer (Fig. 1) is a frame structure made of rod elements, a cabinet open on all sides and made with support on legs 1 on a supporting surface. On one side of the cabinet between the racks 2, a heating panel 3 with infrared radiation (infrared (thermal) radiation in the wave spectrum of 2.5-10 nm) is attached, which is connected with these racks. On the front side of the cabinet for the user, the controller 4 controls the heating panel with the function of setting the time (location may vary).

Such a frame cabinet is assembled from pipes of various sizes or profiles, i.e. rod elements, which are connected by welding or riveting joints or fasteners (bolt connection). In addition, the core elements can be connected via clamps (cabinet dismountability is ensured).

In this case, the cabinet has racks 2 and cross members 5 between the racks, providing it with spatial rigidity. The racks end with support legs 1 (wheels can also be used to provide mobility).

In the upper part of the cabinet above the upper transverse rod elements connecting the racks, a shelf 6 of mesh for organizing hats is organized. This shelf can be made with sides 7. The use of a grid allows passing upward heat fluxes to dry hats.

A heating panel 3 with IR radiation (or a combination panel made of separate heating plates with IR radiation each) is placed between two racks on one side of the cabinet and is made with a length equal to the height of the cabinet according to the distance between the transverse rod elements connecting the racks, to which the heating panel is attached. Thus, this panel occupies the entire wall area (it is believed that this is the back wall of the cabinet). On the front side of the cabinet an open opening is organized for free access to the hangers 8. A large number of heating panels with infrared radiation of various designs are currently being produced. In this regard, there is no need for evidence and examples on the use of specific types of such panels. For the claimed utility model, the concrete panel design is not essential and may be any of the known ones. The main thing is that this heat radiator is made in the form of a panel.

A feature of the claimed utility model is that the cabinet is divided in height into two sections 9 and 10, in the upper 9 of which it is hung located under a shelf of mesh, and in the lower 10 - half the height of the cabinet from the legs to the specified transverse bar elements connecting between a rack. In the claimed model, in each section it was hung made in the form of two rod elements horizontally spaced apart from each other for hanging on clothes hangers in a checkerboard pattern. With this arrangement, there are no zones of contact between clothes to each other, there are air passages between clothes that are dried by objects. Hangers 11 on hangers can be permanently placed (fixed), and can be removable. All hangers on hangers in each section are staggered to ensure the same order when hanging clothes to be dried. When the clothes are staggered, objects are washed from all sides with the same heat flux propagating in the form of radiation in the horizontal direction. And the ascending heat flows through the grid of the upper shelf and dry the hats. In addition, with a low-lying heating panel, radiation also passes through the clothes towards the grid of the upper shelf. Thus, the overall drying efficiency is sharply increased and the drying time is reduced. The controller is used for manual or automatic control in terms of setting the drying time and radiation intensity. The design of the controller is not considered, since it is a standard current or power controller with a built-in timer to automatically turn off the power supply to the panel.

The implementation of the cabinet with two sections allows drying in each section of short clothing (t-shirts, overalls, trousers, jackets, etc.), and long clothes are hung in the upper section with its floor in the lower section.

A feature of the claimed model is that this dryer, in fact, is a separate drying module, which can be used in cabins at industrial enterprises, sports clubs, etc. When there is little space, and you need to dry a large amount of clothing and shoes, such cabinets (especially if the frame is made of collapsible) is more suitable to use than separate stationary installations.

As a drying module, the device can be used to organize drying systems (Fig. 2) and drying rooms (Fig. 3). For accelerated drying, it is necessary to arrange a pair of modules - opposite each other (Fig. 2), you can use the new algorithm for drying clothes. Such an algorithm can be used for large volumes of clothing, for example, special work clothes, when the clothes must be dried overnight or in a short period of time. When two dryers are located opposite each other in the first module, wet clothes are hung in a checkerboard pattern, and in the second module, wet clothes are hung in a checkerboard pattern in the upper and lower sections. Turn on the power for the panels. Drying of clothes in the filled sections occurs as described previously, that is, from the side of the radiation from the panel. But at the same time, the thermal radiation (heating of the panels is not more than 60 ° C) from the panel of the unfilled section opposite passes towards the clothes in the first module. Clothing is simultaneously under the influence of two thermal streams running towards each other (in Fig. 2, the streams are shown by arrows). IR rays diverge from the panels by 120 °, which allows you to block the heat rays of a large surface area of objects for drying. Or, when two dryers are located opposite each other in the first module, wet clothes are not hung up, and in the second module, wet clothes are staggered in both sections.

Thus, the drying time is halved compared to drying clothes in one module as a stand-alone device.

The accelerated drying algorithm considered is a variant of conventional drying, in which all sections of two modules facing each other are filled with clothes hung in a checkerboard pattern. And drying in a variant of a conventional rack will take a little longer, since heat flows passing through clothes weaken and on the other side of the clothes the drying intensity decreases. But this is only in comparison with the considered accelerated drying algorithm. In relation to the prototype, even when fully filled with clothes in all sections in two modules, drying will be reduced in time. At the same time, since thermal radiation blowing occurs over the entire surface of the garment (on the one hand, directly from the panel, and on the other hand, from oncoming flows passing through the garment), the structure of the material from which the garment is made does not undergo thermal drying.

And combinations of a larger number of modules placed opposite each other in a separate room, as shown in FIG. 3, allow you to organize at the factory or at the consumer services plant drying rooms of gentle drying in a short period of time. Given the wide angle of divergence of the emerging rays from the panels, conditions are created under which the radiation from each cabinet or its section is distributed in the direction opposite the located modules. A uniform field of heat flows is created, due to which the flows themselves in the form of wave motion can dry a large amount of clothing.

To increase the spatial rigidity of the frame cabinet, a well-known gain technique is used due to the use of braces (Fig. 4). For the module construction under consideration, brackets 12 are fixed in the lower part between the racks that form an open opening from the side of access to the sections of the side walls and the racks between which the heating panel is placed, that is, in the plane of the elements of the side walls of the cabinet. These braces can be used as supporting elements for placing on them an additional obliquely placed shelf 13 for drying shoes (Fig. 4). To fix such a shelf on the braces, there are elements of placement (installation or fixing) of such a shelf.

This utility model is industrially applicable; it can be manufactured on an industrial scale using general engineering technologies and thermal infrared emitters widely produced by the industry. The design of the frame cabinet and the order of hanging clothes in it ensures high efficiency of gentle drying of clothes in a short period of time due to the uniform and equal heating of each piece of clothing by the heat flow.
