Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a gas stove that uses liquefied fuel gas such as liquefied butane (LPG) as fuel.

<Prior Art> Conventional gas stoves cannot be used in locations without gas piping because liquefied fuel gas needs to be taken in from outside the gas stove body. Furthermore, even if gas piping is available, it is necessary to connect the gas stove with a gas hose, which poses a risk of tripping over the gas hose, which poses safety and appearance problems.

<Prior Application Technology> Therefore, the present applicant has disclosed a technology (Utility Model Application Publication No. 59-91157) that can eliminate the conventional drawbacks. In the technology related to this prior application, the liquefied fuel gas container is removably housed in the gas stove body, but when the burner of the combustor is fired in this gas stove, the temperature of the container changes due to the liquefied fuel gas inside. Due to the heat of vaporization, the pressure inside the container decreases as shown in Figure 7. Therefore, the amount of heat generated decreases, and combustion will no longer occur if the temperature of the container falls below 0°C. FIG. 7 shows the relationship between vapor pressure and temperature inside the container. In this phenomenon, the lower the amount of liquefied fuel in the container, the more significant the decrease in the temperature of the container becomes.

<Purpose> In view of the above, the present invention aims to provide a gas stove that can prevent the temperature of the container from decreasing due to the heat of vaporization of liquefied fuel gas and improve the heat generation of the combustor.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. The gas stove according to the present invention is provided with a storage section 3 for storing a liquefied fuel gas container 2 in a gas stove main body 1, The container 2 is removably housed in the storage part 3, and the gas stove main body 1 is provided with a connector 5 for removably connecting the container 2 and the combustor 4 on the side of the gas stove main body 1. It is.

Then, the radiant heat of the combustor 4 is transferred to the main body 1 into the container 2.
A heat guide path A is formed to guide the heat to the side, and a reflecting plate 6 is disposed in the heat guide path A to reflect the radiant heat of the combustor 4 and heat the container 2.

The gas stove main body 1 consists of a synthetic resin stand 7 having a U-shaped cross section and an opening at the bottom, and a hollow case 8 placed on the stand 7.
The combustor 4 includes a gas burner 9 at the front of the case 8,
An injection nozzle 10 for ejecting vaporized gas to the burner 9
, a piezoelectric spark plug 11 that ignites the burner 9 by spark discharge, a pipe 12 that connects the nozzle 10 and the connector 5 at the top of the case, a device plug 13 provided in the pipe 12, and the device. It comprises an operating knob 14 arranged on the top surface of the case for operating the plug 13, and a wire mesh incandescent body 15 fixed to the hole wall of the top opening 8a of the case 8 above the burner 9. be.

The heat guide path A is formed in the hollow part of the case 8 and extends from the opening 8a under the incandescent body 15 to the storage part 3. and said metal (e.g. stainless steel)
The reflecting plate 21 has a dogleg-shaped cross section, its inner surface serves as a reflecting surface 6a, and one end is fixed to the mounting table 7 at the middle of the heat guide path A with a screw 6b via a heat insulating material 7a. The reflective surface 6a of the reflective plate 6 has a metallic luster and is set at an angle that allows the radiant heat of the incandescent body 15 to be reflected to the lower part of the container 2 on the rear side of the case.

The storage section 3 is provided on the rear side of the case 8, and a support tube 17 with a container insertion hole is formed on the upper surface of the rear portion of the stand 7. The cylindrical container 2 is inserted through the lower opening of the pedestal 7, and its lower end surface is supported by a synthetic resin attachment stopper 18 fitted inside the support cylinder 17.

In the above configuration, the container 2 is inserted through the opening of the stand 7, placed inside the storage section 3, and connected to the connector 5. After setting the container 2 on the connector 5, attach the mounting plug 1.
8 is fitted into the support tube 17 to hold the container 2 in the storage section 3. When the knob 14 is opened, the liquefied fuel gas in the container 2 flows through the connector 5, the appliance plug 13, the piping 12, and the nozzle 10 to the burner 9, and is ignited by the spark discharge from the ignition plug 11, resulting in red heat. The body 15 becomes red hot and the room is heated.

The radiant heat from the red-hot body 15 heated by the combustion of the burner 9 passes through the opening 8a and is reflected by the reflective surface 6a of the reflector plate 6, thereby heating the lower part 2a of the container 2.

Figure 5 shows the relationship between the combustion time (residual amount of gas) and the container temperature at a room temperature of 5°C. Since the container is preheated, the temperature of the container rises to 5° C. or more, and a decrease in the amount of heat generated by the burner 9 can be suppressed.

<Effects> As is clear from the above description, the present invention provides a gas stove in which the gas stove body is equipped with a liquefied fuel gas container and a combustor, in which the gas stove body is provided with a gas stove for guiding radiant heat from the combustor to the container side. The present invention relates to a gas stove characterized in that a heat guide path is formed, and a reflecting plate for reflecting radiant heat from a combustor to heat the container is disposed on the heat guide path.

Therefore, according to the present invention, the temperature of the container due to the heat of vaporization of the liquefied fuel gas can be prevented by heating the container by reflecting the radiant heat of the combustor with a reflector, thereby suppressing a decrease in the calorific value of the combustor. It has excellent effects if it can provide a gas stove with a simple structure.
