Cordless warmer

Abstract

The present invention relates to a wireless warmer, which can be integrally quantized, can be heated to a suitable temperature, and has an enough thickness. The cordless heating pad is a heating element 3 generating heat by electric power supplied from a battery 1 embedded in a case 2 and heats a radiator plate 4 fixed on the surface of the case. The case 2 has a supporting plate 30 on the inner surface of the radiator plate 4 and a surface plate 20 in a manner to oppose to the supporting plate 30 so that the part between the supporting plate 30 and the surface plate 20 is provided as a housing part 5. An intermediate reinforcing plate 10 is disposed between the supporting plate 30 and the surface plate 20. A boxlike supporting rib 22 formed by connecting to the surface plate 20 is provided between the intermediate reinforcing plate 10 and the surface plate 20 so that the intermediate reinforcing plate 10 is supported by the boxlike supporting rib 22. In addition, a supporting rib 32 is provided by connecting to the inner surface of the supporting plate 30 to support the supporting plate 30 by the intermediate reinforcing plate 10 through the supporting rib 32.

Description

[0001] This application is a divisional application of a patent application with an application date of November 7, 2008, an application number of 200810174885.1, and an invention name of "wireless heater". technical field [0002] The invention relates to a battery-type wireless heater. Background technique [0003] A heater used with a commercial power supply is used by connecting the power cord to an outlet. The power cord gets in the way when the heater is in use. Especially when used in a hospital etc., the power cord is in the way. As a heater that eliminates these disadvantages, a cordless heater incorporating a heat storage material has been developed (see Patent Document 1). [0004] The cordless heater described in this patent document heats the heat storage material with a heater and uses the heat stored in the heat storage material in a state where the cord is detached. Since this cordless heater heats up by dissipating the heat stored in the heat storage mate...

AI Technical Summary

Problems solved by technology

This cordless heater heats up by dissipating the heat stored in the heat storage material, so it is difficult to maintain a certain temperature for a long time, and the temperature decreases with use

Increasing the heat storage material can reduce the temperature drop, but if the amount of heat storage material is increased, the overall weight will be too heavy and it will be inconvenient to use.
