A number of devices are known for heating shoes made in the form of an insole and including a battery, electrical components: heating elements, thermostats, on-off devices, while the devices are connected mechanically, and the battery connected to the insole via a long wire is attached or on the shin, or on the outside of the shoe, or fits in the user's pocket (see patent EP 1962024 "Auf Basis emeuerbaber Energietager arberitendes Warmwasser-und Heizungssystem", filing date 02.26.2007, published on 08.27.2007; nt CN No. 2219606 "Electrothermal sole", publication date 1407.07.2003; patent WO 2008006731 "HEATER DEVICE FOR FOOTWEAR GOVES AND THE LIKE", priority date July 13, 2006, published on July 7, 2006; CN patent No. 201199990 Heating shoes, filing date 04/27/2001; published on 08/20/2002; patent CN 201234602 Electrical heating shoes, 07.24.2008, publication date 05/13/2009; patent CN 201370168 Middle soles of heating shoes ”, priority date 3/5/2009, publication date 12/30/2009; patent CN 2219606 "Electrotermal sole", priority date 04/27/1995, publication date 02/14/1996; patent CN 201356114 "Health heating shoes", priority date 02/20/1009, publication date 12/9/2009)

In addition, 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 technical solution is a device for heating shoes in the form of an insole, which is a multilayer structure comprising upper and lower parts, which are made of a polymeric material and equipped with protective inserts 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 include an on-off device, a temperature sensor, transistors, heating elements - resistors, an LED (see patent EP 2215918 "Electrical heated insoles for footware and control heating system for electrical insoles for footware", priority date 01/23/2010; publication date 11/08/2010).

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 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.

The specified technical result is achieved by the fact that the heated insole, made of a multilayer, between the upper and lower parts of which are made of polymeric material and equipped with protective inserts, there is a built-in power source - a battery connected to a device for connecting to an external power source, and an electric board with electrical components including an on-off device, a temperature sensor, transistors, heating elements, an LED, according to the invention, a thermal sensor of size It is also inside an additionally installed control unit that controls the temperature and is connected to an on-off device that is automatic, while the device for connecting to an external power source is a USB port.

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.

Technical solutions that coincide with the totality of the essential features of the claimed invention have not been identified, which allows us to conclude that the claimed invention meets such a patentability condition as “novelty”.

The claimed essential features that predetermine the receipt of the specified technical result, do not explicitly follow from the prior art, which allows us to conclude that the claimed invention meets such a patentability condition as "inventive step".

The patentability condition "industrial applicability" is confirmed by the example of a specific implementation of the heated insole.

The invention is illustrated by drawings, where

Figure 1 is an assembly drawing of a heated insole;

Figure 2 is a schematic diagram of a heated insole.

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, preserving elasticity at low temperatures, with increased adhesion to various materials (see, for example, http://www.msplast.com). The outer side of each of the parts, 1.1 and 1.2, is covered with a protective layer 2.1 and 2.2, made, for example, of textile material or fiber. 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 of a waterproof fabric material.

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, recesses (grooves) are made to accommodate the elements of a flexible electrical board 4 located between parts 1.1 and 1.2.

Board 4 contains electrical components. In the nose zone of the board 4, a control unit for controlling the insole operation is mounted - a microcontroller 5 with an integrated temperature sensor (not shown in the drawing) that measures the temperature inside the shoe. To heat the toe zone of the insole, heating elements are used in the form of resistors 6.1-6.n, the voltage of which is supplied through a transistor 17 controlled by a microcontroller 5. Reliable operation (closing) of a transistor 7 is provided by a resistor 8.

The board 4 is equipped with a built-in power source - the battery 9 located under the board, while the contacts 10 of the battery 9 are located on the board in the heel zone of the insole and serve to power the board 4. To recharge the battery 9 and dry the insole, an external charger connected to the USB port 11 is used device (not shown in the drawing), including that used in automobiles, equipped with a USB connector.

Simultaneously with the recharging of the battery 9, the insole is dried, for which an additional voltage is supplied through pin 12 of the USB port 11, the presence of which is determined by the microcontroller 5 through resistors 13 and 14.

In the heel zone of the base is placed the indicator 15 of the device, made in the form of an LED, and a sensor 16 connected to the microcontroller 5 and used to start it. The sensor 16 is automatically triggered under the weight of the user when using shoes. The sensor consists of, for example, a foil-coated PCB, a flexible membrane, an insulating element with a through hole located under it, and 4 contacts located on the board that enter the hole of the insulating element. The membrane serves to close the contacts of the sensor, which starts the microcontroller 5, which checks the temperature of the insole using a temperature sensor. If the temperature inside the insole decreases and it is necessary to increase it and maintain it at a predetermined level, the microcontroller transmits a signal through the temperature sensor to the heating elements 6.1-6.n. To limit the current, a resistor 17 is connected to the LED 15.

The voltage filtering on the battery 9 is performed by the capacitor 18, while the voltage from the battery 9 to the insole of the insole is supplied through the diode 19.1, and the voltage from the external charger to the board 4 is supplied through the diodes 19.1 and 19.2.

The voltage on the microcontroller 5 filters the capacitor 20, while the operating mode of the microcontroller 5 provides a circuit of a resistor 21 and a capacitor 22.

The claimed 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. During walking, under the influence of weight, the sensor 16 automatically activates, from which the signal enters the microcontroller 5, which, using the built-in temperature sensor, measures the temperature inside the shoe and, if the temperature is below the minimum set value, for example, 28 ° C, the microcontroller transmits a heating command through transistor 7 to resistors 6.1-6.n. Insole heating continues either until the maximum preset temperature, for example, 40 ° C, is reached, or for a predetermined time interval, for example, 5 minutes. The heating process is controlled by a microcontroller 5, which, using frequent light pulses sent by the LED 15, informs the user about the process. Upon reaching the set temperature, the LED 15 turns off. The device automatically turns off after the user has taken off his shoes.

Example 2

The preparatory stage is to connect a charger with a USB connector to the insole via the USB port 11, while charging the battery 9 and drying the insole at the same time. The user receives information about the ongoing process of charging and drying in the form of light pulses sent by LED 15. The microcontroller 5 is launched to perform drying when an external charger is connected via resistor 13.

The claimed invention has a number of advantages over known technical solutions, namely, the automatic on-off device; built-in battery; simultaneous drying and recharging of the battery, for which any external charger, including that intended for the car, is used.
