Description

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

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.

Thus, a shoe dryer is known, comprising a cabinet with walls and a door, made with the legs resting on a support surface, inside of which perforated horizontal shelves for placing shoes are located one above the other, a heating unit for supplying thermal radiation in the direction to the locations of the shoes made in the form of a panel with a coil through which a carrier of heat transmitted through the wall to the cabinet volume flows, as well as a heating unit control controller with a time setting function (KR 20030089523, A47L 23/20, publ. l. November 22, 2003). This decision is made as a prototype.

The disadvantage of this solution is that the drying takes place in a closed volume in which the air mass with fumes from the drying shoes is in a stagnant state. To increase efficiency, a fan is located inside the cabinet, which moves air throughout the cabinet. Such drying requires considerable time for the gradual drying of the shoes, so as not to spoil it by local drying. A humidity control and air change system is also required to remove pairs of shoe material from the cabinet. The use of heating with a coil through the wall of the panel requires the use of a heating system, which is complex in design and energy-intensive. At the same time, to exclude heat losses of the heating system, the cabinet walls are made insulating, which complicates the design of the cabinet as a whole.

Currently, infrared drying systems are widely used, which can significantly simplify, speed up and reduce the cost of this process. At the same time, the quality of finished products (dried clothes or shoes) 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 warm season, you can dry on the street under a canopy. With infrared drying, the dried materials 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. The dried material does not undergo structural changes.

This useful model is aimed at achieving a technical result, which consists in increasing the efficiency of drying shoes by forming separate for each shelf with shoes heat fluxes of infrared radiation with an open architecture of the drying cabinet itself.

The specified technical result is achieved by the fact that in the shoe dryer containing a cabinet made with the legs resting on a supporting surface, inside of which are located one above the other shelves for placing shoes, a heating unit for supplying thermal radiation in the direction to the places of placement of the shoes, and the control unit for controlling the heating unit with the function for setting the time, the cabinet is made of a frame structure of rod elements and is open on all sides, each shelf is inclined, made with elements shoe installation with the toes up and with through passages between these elements, and the heating unit is made in the form of heating panels with infrared radiation, located inside the cabinet frame obliquely one above the other and each of which is placed under the corresponding shelf in an inclined position corresponding to the inclination of the shelf, for transmitting IR radiation through the aisles to the shoe locations, with a reflective layer on the back of each heating panel with IR radiation to reflect the upward sweat ka-IR radiation from the downstream to the shelf placements of shoes on the same underlying shelf.

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 shoe dryer;

FIG. 2 is a demonstration of thermal radiation fluxes in an oven.

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

Such a shoe 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. Such a frame cabinet is assembled from pipes of various sizes or profiles, that is, from rod elements that are connected using 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 3 between the racks, providing it with spatial stiffness. The racks end with support legs 1 (you can also use the wheels to ensure mobility).

Inside the frame cabinet are located one above the other shelves 4 for placing shoes, each shelf is inclined, made with installation elements 5 of the shoes in an upright position and with through passages between these elements. In fact, each shelf is a frame with cross members fixed rigidly or removably to the racks. And on each cross-member and on the elements of the frame itself, mounting elements in the form of pins oriented in a vertical (inclined, close to vertical) direction are fixed. Shoes put on the toe on the pin and remain in this position with the toe up.

On the elements of the cabinet there is a heating unit for supplying thermal radiation in the direction to the shoe locations and a heating unit control controller with a time setting function (not shown), displayed on the front side of the cabinet (location may vary).

The heating block is a set of heating panels 6 with infrared radiation (infrared (thermal) radiation in the wave spectrum of 2.5-10 nm) located obliquely inside the cabinet frame one above the other and each of which is placed under the corresponding shelf in an inclined position corresponding to tilt the shelf to transmit infrared radiation through the aisles to the shoe locations. At the same time, on the back of each heating panel with infrared radiation there is a reflective layer 7 or a coating in the form of reflective thermal insulation to reflect the upward flow of infrared radiation from the lower shelf to the shoe locations on this lower shelf (this process is shown in Fig. 2) .

Currently, a large number of heating panels with infrared radiation of various designs are 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.

Drying of clothes in the cabinet occurs from the side of radiation from the panel. But at the same time, thermal radiation (heating of the panels no more than 60 ° C) from the panel rises up, passes through the aisles in the shelf, washes the shoes, is reflected from the reflective layer, being cooled, and partially lowers towards the shoes. Other streams after passing the aisles, passing by the shoes, in the transverse direction are removed from the cabinet into the environment. Thus, in a space bounded by two adjacent adjacent heating panels with infrared radiation, heat fluxes move, which provide not only a change in heated air, but also drying shoes in a gentle washing mode. Since infrared radiation has the ability to penetrate the structure of the material, drying does not take place superficially, but along the depth of the material structure, which ensures the safety of the shoe, regardless of what material it is made of. It is known that during drying evaporation leaves the material, the vapors of which smell unpleasantly. Especially when it comes to drying shoes made of genuine leather or natural suede. Therefore, these vapors are naturally removed into the environment by heat fluxes leaving the cabinet. In addition, currently shoes made of suede or genuine leather, according to the recommendations of manufacturers, are sprayed by the user from the outside with compounds that provide a water repellent coating on the surface of the shoe. But the inner surface of the shoe with these compounds is not sprayed. Therefore, if the boot is wet from the inside, then the external thermal drying in the usual convective way leads to the drying of the outer layers of the material until the boot dries from the inside. And when drying with IR radiation, thermal rays pass through the outer layers and excite water molecules inside the soaked layers, which leads to drying of the shoes from the inside without damaging the dry outer surface.

For complete washing by heat flows of shoes, the latter is located on inclined shelves, and therefore the shoes are simultaneously under the influence of two heat flows (in Fig. 2, the flows 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.

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 arrangement of the heating IR panels provides high efficiency for gentle drying of shoes in a short period of time due to the uniform and equal blowing of the heat flow of each item of clothing.
