Description
Heating insole The present invention relates to a heating insole, and more specifically, to a heating insole that generates heat to maintain foot temperature. Generally, an insole is installed inside a shoe to provide comfort to the foot. Regarding the above-mentioned insole, Publication No. 10-2018-0113085 describes a first insole in which a first air flow groove is formed in a grid pattern on the lower surface, and a ventilation hole is formed penetrating the intersection of the first air flow groove in the vertical direction; A second insole having a second air flow groove formed on its upper surface having a shape symmetric to the first air flow groove, and the upper surface being coupled to the lower surface of the first insole; and An insole having a ventilation hole formed on its side is disclosed, characterized by including an air flow channel formed by the interlocking of the first air flow groove and the second air flow groove and communicating with the ventilation hole. Additionally, Publication No. 10-2016-008980 discloses a hybrid functional insole characterized by being composed of an elastic foam layer forming the entire front part and a lower part or the entire rear part of the insole, and an elastic gel layer forming the upper part of the rear part of the insole. However, the above prior art had the disadvantage that the insole did not generate heat well. FIG. 1 is a diagram of the heating insole of the present invention. FIG. 2 is a configuration diagram of the controller of the present invention. The present invention is characterized by having a heating element formed to maintain the temperature. In addition, the above-mentioned heating element is characterized by its temperature rising due to friction. In addition, it is characterized by the installation of an electric heater in the insole. In addition, it is characterized by having friction heat generating particles coated on the insole. The present invention will be described in detail with reference to the attached drawings as follows. FIG. 1 is a configuration diagram of the heating insole of the present invention, and FIG. 2 is a configuration diagram of the controller of the present invention. The present invention maintains foot temperature by forming a heating element in the insole. The temperature of the heating element rises due to friction. Friction heat generating particles are coated on the insole. Additionally, an electric heater is installed in the insole. For friction heating, the insole is manufactured using fibers containing capsaicin. Therefore, heat is generated through friction with bare feet or socks. Furthermore, an electric heater is installed separately and generates heat using electricity supplied by a battery installed between the insole and the outsole. A sensor and a controller are installed separately; the controller activates the electric heater when the temperature measurement value transmitted from the temperature sensor is lower than a certain temperature or lower than the set value stored in the storage unit. In other words, the electric heater is turned on as an auxiliary measure when friction heat alone is insufficient. The controller consists of a control unit, a storage unit for storing data, and a comparison unit for comparing the set value with the measured value. The temperature sensor is mainly installed on the side or the bottom of the insole. Meanwhile, since suddenly turning off the electric heater when sweating during exercise poses a risk of catching a cold, a moisture detection sensor is primarily installed on the side or bottom of the insole. In normal mode, the control unit turns the electric heater on and off based on the temperature sensor; however, if the sensor detects moisture, it switches to a delay mode, and the time the electric heater remains off is extended compared to normal mode by means of a delay circuit. The insole is manufactured by making it extremely thin to facilitate temperature detection, by making it in a mesh form, or by injection molding a mixture containing particles such as metal that facilitate heat conduction. Therefore, the present invention has a significant effect of keeping the feet warm even in winter by installing a heater in the insole.
