Description

A rechargeable heating insole

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an insole for shoes, and more particularly, to a rechargeable heat generating insole having a heat generating function.

If you work outdoors in cold climates, such as mountain climbing, skiing, or work in extreme low temperature conditions, such as in a freezer, it is easy to get frostbite on your feet, so keep your feet warm. Normally, in this environment, thick winter shoes are worn, but these shoes are thick and heavy, which makes the activity uncomfortable.

In recent years, a heat-generating shoe disclosed in Korean Patent Publication No. 2002-26203 has been proposed for wearing in such an environment. In this shoe, a battery for power supply is installed in the back heel of the shoe, and a surface heating element which generates heat by power supply is installed on the rug accommodated in the shoe. In addition, a switch operated by pressure is installed at the contact point of the bottom of the rug so that the power can be supplied only when the shoe is worn. This is because power is supplied from the battery to the surface heating element of the rug when the shoe is worn, so that the warmth can be provided to the wearer's feet that perform cold winter outdoor activities.

However, since such heat-generating shoes continuously generate heat during wearing, it is difficult to provide a comfortable feeling such as sweating on the feet due to a rise in temperature in the shoe in some cases.
