Description

[Detailed Description of the Invention] The present invention relates to a household thermos flask with a built-in electric heating element.

Hot water stored in a thermos bottle maintains its temperature for about a day, but it cannot maintain that temperature for several days.

In the past, thermos bottles with built-in electric sheathed heaters have been devised in order to maintain the temperature of hot water in the thermos bottle for several days, but they have not been widely used in the market and their useful value has not been recognized.

Therefore, in order to maintain the hot water, this invention
The purpose of this electric heating thermos bottle is to focus only on heat retention and to limit the ability of hot water stored in the thermos bottle to maintain its temperature for several days, so that it can be used safely.

Next, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side cross-sectional view of a conventionally devised thermos bottle incorporating an electric sheathed heater.

1 is a double glass bottle and 2 is an electric sheathed heater.

FIG. 2 is a side sectional view of an embodiment based on the present invention.

4 is a double glass bottle, and 4' is an inner glass wall of the double glass bottle 4.

Reference numeral 5 denotes an electric heating element for self-temperature control, which is embedded inside the glass wall 4' except at the bottom.

By applying electricity to the electric heating element 5, the side surface 4 of the inner glass wall is heated.
’ is heated, making it difficult for the stored hot water to cool down, so the hot water is forced to undergo heat convection, and instead of being heated violently, it only absorbs the leakage heat that is conducted and consumed from the bottle. It is supplemented and moisturized and can be used for several days without getting cold.

The electric heating element 5 uses a self-temperature-controlled electric heating element that generates as much heat as the hot water cools and limits the generation of more heat, and heats the glass wall 4' to 80 degrees Celsius.
The following steps have been taken to ensure safety in use.

As described above, by implementing the present invention, the hot water stored in the thermos flask 4 can be used for several days without cooling down, as described above, and there is no need for double boiling, which was commonly done in the past.

Furthermore, since no electric sheathed heater is used, the weight of thermos flask 4 is the same as that of a commonly used thermos flask, so it is not cumbersome to use. .
