[0028] detailed description

[0029] An electric heating device of the present invention includes an insulating jacket. The insulating jacket contains a substance or a mixture of several substances with a melting point between 50°C and 81°C, and an electric heating wire in a heating control circuit is placed in the substance Or the temperature of the substance or mixture is controlled in the mixture and through the heating control circuit.

[0030] There are paraffin, stearyl alcohol, wax, stearin and naphthalene with melting point between 50℃-81℃, but the price of paraffin wax is relatively low, and its melting point 54℃ is more suitable. This temperature will not cause ordinary people For burns, even for infants and young children, it is safe to add some towels and the like. Therefore, paraffin wax is selected as the heat storage material in this embodiment.

[0031] Since paraffin wax releases latent heat of fusion when it solidifies, if the latent heat is taken into account, t...

Abstract

The invention discloses an electric heater which comprises an insulating jacket. A substance or a mixture of several kinds of substances with the melting point of 50-81DEG C is contained in the insulating jacket. Heating wires in a heating control circuit are placed in the substance or the mixture, and the temperature of the substance or the temperature of the mixture is controlled through the heating control circuit. According to the electric heater, heat is supplied by mainly utilizing a large amount of latent heat emitted by substances such as paraffin in the solidification process, and therefore safety is high.

Description

technical field [0001] The invention relates to an electric warmer. Background technique [0002] In the autumn and winter seasons when the temperature is low, people often like to use various hot water bags, electric hot water bags, electric heating cakes, electric heating treasures, etc. for heating, especially for the elderly, infirm and infants. [0003] Yet heating equipments such as these electric heating treasures also cause some scalds sometimes when bringing warmth to people. This often occurs when using these heating devices and sleeping soundly in the quilt, especially on some infants and ladies with delicate skin. I have investigated the situation of being burned by electric heaters in a small area, and found that burns are not uncommon. Of course, this has a lot to do with people's living habits. There are several acquaintances who are burned almost every year. Some infants and young children are left with permanent scars after being burned. A professor of ...
