Insoles with the heating element Therm-ic Thermic-Sole Perform ”(http://www.skimaster.ru) or“ Thermosoles Rechargeable yeated insoles ”(http: // www. Verseo.com thermosoles.html ^' ) are known. made of polymeric material, heating elements are located throughout the foot, with each insole having its own control unit, which is mounted on the lower leg or on the outside of the boot, a mechanical (manual) switch allows you to adjust the level of heating.

The closest set of essential features to the claimed invention is a device for heating shoes in the form of insoles, disclosed in the patent for utility model RU 115170, published on 04/27/2012, which is a multi-layer structure comprising upper and lower parts, which are made of polymer material and equipped with protective inserts made of textile fiber. Between the upper and lower parts, there is a battery connected to a device for connecting to an external power source, and an electric board with electrical components, which includes a button to turn on the device, the heating element is presented in the form of a carbon thread in the forefoot of the insole.

The disadvantages of the known design are primarily due to the need for mechanical (manual) start-up of the device (on-off), charging the battery and drying the insole with the obligatory removal of the insole from the shoe.

In addition, the start-up of this device is carried out either mechanically, or by remote control - remote control.

This design does not allow to control and regulate the temperature regime inside the shoe, because functioning occurs only with mechanical switching on, while heating is carried out with the participation of all heating elements - resistors in the temperature range that is predefined.

The disadvantages of the known design are caused, first of all, by the openness of the insole contacts, oxidized in the aggressive environment of the shoe, the inclusion of pressure on the heel, which does not always happen, but only when a person is standing, charging the battery and drying the insole with the obligatory removal of the insole from the shoe. This design does not allow to control and regulate the temperature regime inside the shoe, because functioning occurs only with mechanical switching on, while heating is carried out with the participation of all heating elements - resistors in the temperature range that is predefined. Disclosure of invention

The technical result, the achievement of which the claimed invention is directed, is to expand the functionality of the device due to automatic start and the possibility of simultaneously charging the battery and drying the insole. In addition, the insoles are completely closed, there are no contacts on the outside, which increases the duration of the insoles. Charging is carried out wirelessly using inductive coils.

The specified technical result is achieved by the fact that the insole with heating, made of a multilayer, between the upper and lower parts of which, made of polymeric material and equipped with protective inserts, has a built-in power source - a battery, an electric control board with electrical components, including an on-off device with using a capacitive sensor, a coil for connecting to an external power source, and a temperature sensor, a heating element made either by a board with a transistor According to the invention, the temperature sensor is located inside a heating element that controls the temperature and is connected to an electric control board, which is made automatically, while the device for connecting to an external power source is an induction coil.

The upper and lower insoles are made of a copolymer of ethylene and vinyl acetate. The inserts are made of textile material, including waterproof. Contour lines with markers corresponding to the size of the user's shoes are applied to the outer surface of the insole.

Brief Description of the Drawings

The invention is illustrated by drawings, where:

in FIG. 1 is an assembly drawing of a heated insole, top view;

in FIG. 2 is an assembly drawing of a heated insole, right view.

The implementation of the invention

The inventive device contains a base in the form of an insole, consisting of two parts: upper 1.1 and lower 1.2, made of environmentally friendly polymer composite material, for example, a copolymer of ethylene and vinyl acetate (EVA / EVA) - lightweight, elastic, having good shock-absorbing properties, retaining elasticity at low temperatures, with increased adhesion to various materials (see, for example, http: //www.rusplast.comX The outer side of each part, 1.1 and 1.2, is covered with a protective layer 2.1 and 2.2, made, for example, of textile material or fibers. The lower part 1.2 of the base adjacent to the sole in the forefoot and heel zones is equipped with inserts 3.1 and 3.2 made of waterproof fabric material. In the heel part 1.2 the base has greater rigidity for additional battery protection.

In addition, contour lines with markers are applied to the outer surface of the base, along which an insole of the required size corresponding to the size of the user's shoes is cut, which, in turn, helps to standardize the products. In both parts of the base there are recesses (grooves) for accommodating the elements of the electric board 3, the battery 4, the induction coil 5, the capacitive sensor 6, the heating element 7, located between parts 1.1 and 1.2.

Board 3 contains electrical components. Board 3 using cables, for example MGTF, is connected to a heating element 7 mounted in the nose zone, made in the form of a board with resistances and a temperature sensor or carbon fiber with a temperature sensor (not shown in the drawing), which heats and measures the temperature inside the shoe.

The board 3 is equipped with a built-in power source - the battery 4, installed next to the board in the heel part and protected by a protective housing or a closed protective layer, while the battery contacts are located on the board in the heel of the insole and serve to power the board 4. To recharge the battery 4 and drying the insoles use an external charger connected to the induction coil 5 (not shown in the drawing), including that used in automobiles, equipped with an external induction coil. For proper orientation of the external and internal coils in the external charger and coil 5, a magnet 5.5 is installed in the center of the coil.

Simultaneously with recharging the battery 4, the insole is dried, for which the controller on the board 3 periodically transfers the voltage from charging the battery 4 to the heating element 7.

The capacitive sensor 6 is connected by a cable, for example, MGTF, to the board 3. The sensor consists of two parallel plates made, for example, of foil and coated with a protective layer located in the area of the foot arch, and placed on the board 3 electronic elements (not shown in the drawings). The plates serve to obtain information about contact with the user's body and the change in capacitance that the electronic elements on the board 3 are counted using a microcontroller, which periodically, for example, every 4 seconds, calculates the capacity of the plates 6. In the case of a change in the capacity of the plates 6, the controller on the board 3 supplies voltage to the heating element 7 to heat the insole. The built-in temperature sensor in the heating element 7 transmits temperature information to the controller on the board 3. If the temperature inside the insole decreases and it is necessary to increase it and maintain it at a predetermined level, the microcontroller on the board 3 supplies voltage to the heating of the heating element.

The invention is as follows. The use of shoes with a heating insole can be divided into two stages: basic and preparatory.

Examples of specific embodiments of the invention.

Example 1

During the main stage, an insole for heating is placed in the shoes. When walking, when a person contacts the insoles through the sock, the capacitance of the sensor 6 changes, from which the signal is sent to the microcontroller on the board 3, which, using the temperature sensor on the heating element 7, measures the temperature inside the shoe and if the temperature is below the minimum set value, for example , 28 ° С, the microcontroller transfers voltage to the heating of the heating element 7. Insole heating continues either until the maximum set temperature, for example, 40 ° С, is reached, or during the set time nnogo interval, e.g., 5 minutes. The heating process is controlled by a microcontroller on the board 3. Upon reaching the set temperature, the voltage to the heating of the heating element 7 is turned off. The device automatically turns off after the user has removed his shoes.

Example 2

The preparatory stage is to transfer energy to the board 3 through the coil 5 from the charger with the coil inductively. To increase the efficiency of energy transfer, 5.5 magnets in the insole and a magnet in the coil of the charger are used. At the same time, charging of the battery 4 and drying of the insole are carried out simultaneously. The user receives information about the ongoing process of charging and drying in the form of light pulses sent by the power supply unit of the charger. The claimed invention has several advantages over the known technical solutions, namely, the automatic on-off of the device using a capacitive sensor, which requires neither the user's attention nor pressure on the insoles; built-in battery; wireless charging method, simultaneous drying and recharging of the battery, for carrying out which an external charger is used, including one designed for a car.
