Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a cooking warmer that keeps food warm after it is cooked in a restaurant such as a hotel until it is eaten so that it does not get cold.

BACKGROUND TECHNOLOGY Conventionally, fuel insulators use a combustion of alcohol solid fuel or an electric heater as a heat source.

Problems that the invention aims to solve However, since alcohol burners use open flames, there is a risk of fire, and for disaster prevention reasons, it has been difficult to use them in hotels and restaurants in urban areas. In addition, electric heaters require a large amount of electrical capacity, so it is dangerous to use many at once, and they also have the drawback of requiring a power outlet, which limits the space available and requiring a large amount of equipment cost. .

Means for Solving the Problems The present invention was developed in view of the above, and provides an extremely safe and inexpensive heating device for cooking that utilizes the heat generated by oxidation of flammable vapor such as methanol. The purpose is to

Embodiment One embodiment of the present invention will be explained with reference to the drawings.
1 shows a main body made of heat-resistant plastic, which consists of an upper cylinder 2 and a lower cylinder 3, both cylinders 2 and 3 being removably fitted together. Reference numeral 4 denotes a disc-shaped heat sink made of aluminum attached to the top surface of the upper cylinder, and a ceramic heater 6 made of platinum catalyst metal is attached to the lower surface of the plate via a mounting bracket 5. Reference numeral 7 denotes a fuel pan containing solid alcohol, paste alcohol, or other fuel that generates flammable vapor; 8 a metal coil spring; the spring 8 presses the upper cylinder 2 upward to keep the heat sink 4 warm; Close to the object. Reference numeral 9 is a dry battery that supplies current to the heater 10 for preheating. 11 is a switch for the heater, 12 is a battery removal cover, and 13 is a windproof rubber attached to the outer periphery of the heat sink. Note that a flange 14 for preventing falling is integrally provided on the lower outer periphery of the lower cylinder.

Effects However, in order to use the device of the present invention, steps 3 to 5 are required.
As shown in the figure, this heat insulator is placed in a circular frame 15.
Central attachment part 1 of frame body 17 with book legs 16 attached
Next, a water pan 19 filled with hot water or water is placed on top of the water pan 19 so as to be in close contact with the heat sink, and a food pan 20 containing food is placed on top of the water pan 19. After preparing in this way, when the switch is turned on for 2 to 3 seconds, the heater is heated by the battery, and the alcohol in the fuel pan immediately turns into flammable vapor, causing an oxidation reaction with the ceramic heater's catalyst and generating heat.
This heat is transferred to the heat sink by thermal conduction, heating the heat sink, and the heat from the heat sink warms the water in the water pan, thereby keeping the food in the food pan at an appropriate temperature.

In order to maintain the cooking temperature at around 70°C, it is necessary to raise the water temperature in the water pan to around 95°C and the heat sink to around 140°C. This is possible by adjusting the number and size of the air holes, but by freely selecting the number and size of these air holes, you can freely change the temperature of the insulation. Further, by adjusting the amount of fuel, the heat retention time can be freely adjusted.

In addition, in the example, the upper cylinder is constantly pressed upward by a coil spring, so the height can be adjusted freely, and any commercially available equipment can be used.
Moreover, the adhesion between the heat sink and the water pan is improved, heat conduction is also improved, and heat loss is reduced.

Effects of the invention However, according to the invention, heat is generated by oxidizing flammable vapors such as alcohol using a catalyst, so it is possible to keep food at an appropriate temperature without using any fire. When using a circular frame with legs like this, even if the length of the legs of the frame is slightly different, the springs will always ensure good contact between the heat sink and the water pan, and when not using a frame with legs, the screws will The upper and lower tubes are fixed in place to ensure stable contact between the heat sink and the bottom of the water pan or pot. It is extremely safe and hygienic, can be used anywhere in restaurants such as hotels, and is economical as it does not require equipment such as electrical outlets like electric heaters.
It has the effect of providing an inexpensive cooking warmer, and its practical value is extremely great.
