Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a cooking utensil equipped with a burner.

(Purpose) The purpose is that when the heated container is heated by the flame from the burner, the table on which the heated container is placed and its surroundings are heated wastefully, so the heat is dissipated to the table and surrounding objects and the surrounding area. The idea is to recover some of the heat generated and use it separately.

(Prior art) Cooking appliances equipped with burners, such as gas staple cookers
In order to place a container to be heated such as a pot or kettle, a holder is provided above the burner, and the bottom of the container is heated by applying a flame to it, but the flame may protrude from the bottom of the container or the holder may be placed on top of the burner. It is said that only a few dozen percent of the heat is used effectively, such as by heating and transmitting the heat to the stove body, or by releasing hot air from the gap between the receiver and the stove body.

Conventionally, no attempt has been made to recover this wasted heat.

(Solution Means) The present invention includes directly attaching a heating part of an efficient heat conduction pipe generally called a heat pipe to a receiver for placing a container to be heated, and attaching it adjacent thereto.
In order to use the heat heated there separately, it is extended, or if necessary, it is insulated from the outside and the heat is conducted into the pipe. It is intended to be used separately for boiling water.

(Example) An example of the present invention will be described with reference to figures. Fig. 1 is an external view of a gas staple stove, and 1 in the figure indicates the stove body;
2 is a burner, and 3 is a knob for igniting it and adjusting the length.

Reference numeral 4 denotes a container to be heated, and the container to be heated is placed on its mounting portion 4a.

As shown in the figure, the heat pipe 5 is attached to the side of the burner 2. Although the bottom of the receiver is not shown, it is made of resin to prevent heat transfer to the stove body 1 as much as possible. It has been treated with insulation and processing.

The heating portion 6 of the heat pipe 5 is in close contact with the receiver 4, and the heat transfer area of the contact portion is made as large as possible.

A water tank 7 is provided with a heat radiating part 8 which is an extension of the heat pipe 5, and the heat heated by the heating part 6 is radiated to the water poured into the water tank to warm the water.

The heat pipe 5 also has a heat insulating part 9 between the heating part 6 and the heat dissipating part 8, that is, a part where there is almost no heat exchange from the pipe to the outer periphery. It has a so-called thermal diode property, which allows it to conduct heat very well, but prevents heat transfer in the opposite direction.

10 is a lid of the water tank 7, and 11 is a faucet for taking out the injected water.

Reference numeral 12 denotes a carpet as another example in which the recovered heat is used, and the heat pipe 5' is received by the heat radiating part 8' through the heat insulating part 9' to warm the feet of people working in the kitchen. ing.

Although not shown, a suitable heat storage material is incorporated inside the carpet to maintain warmth for a while even after the burner 2' is turned off.

Figure 2 shows a structural model of a heat pipe 5.5', where 13 is a sealed pipe made of copper, for example, and 14 is a porous pipe that is attached to the inner wall of the pipe in an annular shape and has excellent capillary action. The wick made of material 15 is a working fluid under reduced pressure, such as water.

The pressure inside the pipe indicates the saturated vapor pressure of the working liquid 15 at that temperature, and maintains a state of vapor-liquid equilibrium.

The heating section 6.6' constitutes an evaporation section for the working liquid 15.

The heat dissipating parts 8, 8' likewise constitute condensing parts.

The arrow indicates the direction in which the working liquid 15 moves after being vaporized,
The return path is due to the capillary force of the wick 14.

9, 9' are insulation parts, and pipes 8, 8' are connected with appropriate insulation material 16.
is covered to prevent heat radiation to the outside air.

In the above configuration, for example, when the burner 2 is ignited and the container to be heated, such as a pot, is placed on the receiver 4, the container to be heated is heated by the main heat directed from the burner 2 to the container to be heated. .

The receiver 4 is heated, but most of the heat is conventionally radiated outside without reaching the container to be heated. conducted.

The working liquid 15 in the wick 14 located on the inner wall of the pipe in the heating section removes heat by latent heat of vaporization and is vaporized, increasing the pressure in the pipe in the vicinity.

Therefore, the vaporized working liquid moves toward the heat radiation section 8 where the pressure inside the pipe is low.

Since the outer periphery of the heat radiating portion is in contact with relatively low temperature water in the water tank 7, it radiates heat and liquefies.

The condensed working liquid is drawn back to the heating section 6 by the capillary force of the wick 14 and vaporized again.

The water in the aquarium 7 is heated by repeating this process.

This warmed water can be used for washing dishes, boiling, drinking, etc.

(Effects) As described above, according to the present invention, by installing a heat pipe of a simple structure near the container on which the container to be heated is placed, some of the heat that was wasted in the past can be eliminated. However, it is a useful invention, as it can be recovered and used for boiling water, heating, etc., and can also be used for mild heating cooking such as seaweed grilling.
