RU215505U1 - PORTABLE SHOE GENTLE DRYER - Google Patents

Abstract

The utility model relates to household footwear care products, namely, devices for gentle drying of footwear by heating and extracting moist air. It consists of a plastic case with two separate channels: one for supplying and heating air from the atmosphere, and the second for removing moist air from the boot cavity. Modification in the form of forced circulation of air flows allows to intensify moisture removal.

Description

This utility model relates to shoe care products, namely to devices for drying wet shoes.

A well-known method of drying shoes by direct heating outside and inside the shoe, which can adversely affect the consumer properties of the product, since there is a possibility of detachment of glued joints, detachment of membranes, cracking of the skin and compression of textile elements.

A device for drying shoes is known by direct heating of the resistive element in the cavity of the boot, due to the increase in temperature, the evaporation of moisture is intensified, thereby accelerating the drying process [1].

The disadvantage of this device is uneven heating and low moisture removal, due to only convective circulation of air flows, compared with forced circulation.

The closest device according to the implemented drying technology is a device for drying shoes, in which the principle of drying shoes is based on supplying a preheated air flow to the boot cavity [2].

The disadvantages include the fact that in the drying areas there are only three holes through which heated air enters. That does not provide uniform heating of drying shoes.

The objective of the proposed portable device for gentle drying of shoes is to combine the portability of dryers with resistive heating and the efficiency of the method of forced circulation of air flows with the directed removal of moisture-saturated air.

This problem is solved by completing the exhaust fan and the heating element in a single housing. The design of the device is shown in figure 1.

A portable device for gentle drying of shoes includes a plastic case (1) with inlets (2), a heating element for supplied air (3), outlets in the boot cavity for heated air (4), inlets from the boot cavity for moisture-saturated air ( 5) and exhaust fan (6).

The plastic case of the device is L-shaped for ease of insertion into shoes to be dried and includes two separate coaxial channels: one for supplying and heating air from the atmosphere, and the second central one for removing moist air from the boot cavity.

An exhaust fan (6) is located in the central channel, as well as holes (5) in the housing (1) at the end of the channel. In the surrounding central side channel there is a heating element for the supplied air (3) and openings (2) and (4) in the upper and lower parts of the body (1), respectively.

During the drying process, the boot is softly heated with the help of heated air that enters from the environment through the inlets (2) into the side channel and heats up passing through the electric heating element (3) due to the pressure difference created by the axial fan (6), and enters the cavity of the boot through the outlet holes (4). Further, to intensify moisture removal, moist heated air from the cavity of the boot is sucked into the central channel through the holes (5) due to the operation of the axial fan (6) and is discharged into the environment.

The temperature of the incoming air and the degree of heating can be adjusted by the rotational speed of the axial fan, thus changing the drying mode for different materials. It is also possible to implement automation systems using a humidity sensor at the air outlet. When the set humidity is reached, the device turns off without overdrying the shoes and without consuming electricity.

Thus, the implementation of the proposed device provides a technical result: drying shoes by resistive heating of air with forced circulation of air flows, providing a directed removal of moisture-saturated air. Also, the circulating warm air creates more gentle drying conditions for the shoe material, since it eliminates strong local heating of its areas. The form of the device has a mobile design and low cost compared to stationary industrial dryers.
