Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum double bottle with a heater used for heating, keeping drinks warm, and keeping drinks cold.

Conventional technology Conventionally, this type of thermos flask has either used a vacuum insulation layer to keep it warm, or as shown in Japanese Utility Model Application Publication No. 57-94428, it has used the heat insulation effect of a vacuum insulation layer and heating with an electric heater. There are things etc.

Problems to be Solved by the Invention However, the former method has the disadvantage that drinks, etc., eventually get cold, and the latter method has the disadvantage that it cannot be heated in a place without a power source.

Means for Solving the Problems The present invention has been made in order to eliminate the above-mentioned drawbacks, and its purpose is to obtain a vacuum double bottle with a heater (hereinafter referred to as a bottle) that has good heat retention efficiency and is not limited to the location where it can be used. . For this purpose, a fuel cell is used to heat the heater.

It is equipped with a water tank to store water generated when the fuel cell operates.

By doing this, the heat retention effect is improved by the vacuum section, and the heater can be heated by replenishing fuel even in places where there is no power supply.

Example Two embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a thermos body and an outer bottle 101 made of stainless steel.
A vacuum section is formed in the space 103 between the inner bottle 102 and the inner bottle 101 and the inner bottle 102. 3 is a heater with a built-in heating element (not shown) and a gasket 4.
It is fixed to the inner bottom of the inner bottle 102 in a water-tight manner via the communication part 104. A lead wire 301 connected to a fuel cell 7, which will be described later, is led out into the bottom body 2, which will be described later. or,
The communication portion 104 is made of a thin member with high thermal resistance in order to reduce heat dissipation. 5 is a beverage, inner bottle 10
2 through the mouth 105; 9 the plug 6 of the mouth 105;
It is sealed by. 2 is the bottom body, outer bottle 10
A companion piece is provided at the bottom of the thermos flask body 1, consisting of a side part 201 and a bottom part 202, to integrally support the thermos flask body 1. Reference numeral 7 denotes a fuel cell, which is provided in the bottom body 2, and a water tank 8 is connected to the bottom of the fuel cell 7, and is fixed to the bottom part 202 with a support 206. Reference numeral 205 denotes a replenishment port, which is a part for replenishing fuel from outside the side portion 201. Holes 206 and 204 are provided in the side portion 201 and the bottom portion 202, respectively, and are air outflow and inflow portions for supplying air to the fuel cell 7. 207
and 208 are a discharge pipe and a valve body, respectively, which are used to discharge water generated during operation of the fuel cell 7 and stored in the water tank 8 to the outside of the thermos bottle body 1. Reference numeral 9 denotes a switch, which is provided on the side portion 201 for use in controlling the supply of electricity to the heater 2 as necessary.

Next, the operation of this embodiment will be described.

A drink 5 is put into the inner bottle 102 through the mouth part 105 and the stopper 6 is closed. Methanol is supplied into the fuel cell 7 from the supply port 205, and the switch 9 is turned on. At this time, the fuel cell 7 is supplied with air as shown by the arrow A from the hole 204 to generate electricity, and the heater 6 generates heat via the lead wire to heat the beverage 5. Therefore,
Fuel cell 7 has negative electrode CH30)1+H20-')6H"+CO
2+6e (electron) to positive electrode 6H"1'02+6e -
+ 3H20 reaction container 9. Water and monocarbon dioxide are produced.

Also, since the fuel cell 7 generates heat during reaction (operation), arrow A
Air is sucked through the hole 204 as shown in the arrow B from the hole 206.
It releases carbon dioxide gas like this. Further, water generated during the reaction is introduced into a water tank 8 and stored therein.

After the water in the water tank 8 is used, the valve body 208t opens and is discharged to the outside of the thermos flask body 1 through the discharge pipe 207. When the switch 9 is turned off, heating of the heater B is stopped.

In the US example, an example related to a thermos flask was shown.

By having a similar configuration, it is also possible to apply the present invention to cooking utensils such as electric rice cookers.

Effects of the Invention As described above, according to the present invention, by incorporating a fuel cell into a bottle and providing a water tank for storing water and gold generated during the operation of the fuel cell, heat retention efficiency is improved by the vacuum section, and fuel can only be replenished. It is possible to obtain a bottle that is extremely easy to use and can be used in any location.
