Description

[Detailed Description of the Invention] The present invention relates to a gas stove that emits heat radiation from the front.

Conventionally, this type of stove is known to have a cylindrical gas burner on a base with its peripheral surface serving as the combustion surface, and a reflector that surrounds the burner from the back to both sides. In this case, it is preferable that the stove is capable of switching its heating power between high and low levels, and furthermore, it is preferable that the burner does not appear dark in its low state.

The purpose of the present invention is to obtain a stove that meets such requirements, and includes a gas burner 2 whose peripheral surface is the combustion surface on a base 1, and a gas burner 2 that extends from the back side to both sides of the gas burner 2. In the burner 2, the burner 2 is divided into a front half 2a and a rear half 2b, to which gas is supplied separately. It is characterized in that the firepower is adjusted by turning on and off the rear half portion 2b.

The above-described structure of the burner 2, in which the peripheral surface is used as the combustion surface, and the inside thereof is divided into two halves 2a and 2b, and gas is supplied to each half separately, is disclosed in, for example, Utility Model Application No. 57-108516. As stated in the publication,
According to the present proposal, this was arranged in the front and rear directions in both halves 2a and 2b as clearly shown in Figures 2 and 3, and the firepower could be adjusted by turning it on and off in the rear half 2b. . To explain further, the rear half portion 2b is connected to a gas supply pipe 5 via a switching valve 4, and gas supply is turned on by operating the valve 4.
The ignition burner 7 is of the type that is turned off and is opposed to it through the ignition flame window 6, and the front half 2a.
The front half 2a is further provided with a thermocouple 10 connected to the gas safety valve 9 on the upstream side of the switching valve 4.

To explain its operation, when the rear half 2b is ignited by the ignition burner 7 and is activated for combustion, the front half 2a is ignited by the flame transfer device 8 and is activated for combustion. The gas safety valve 9 is kept open by generating an electromotive force in the thermocouple 10, and according to the combustion operation of both halves 2a and 2b, the second
Heat radiation is generated as shown by the dotted line arrow and the solid line arrow in the figure, and the thermal power adjustment becomes strong. Next, to make this a weak state, the gas supply to the rear half 2b is cut off using the switching valve 4, so that only the front half 2a becomes combustible, and the heat radiation is shown by the solid line arrow in Fig. 2. Although this is only shown, when viewed from the front, the front half 2
This appears red due to the combustion operation of part a, and the dark color of the non-combusted rear half part 2b is hidden by this and cannot be seen directly. Thus, there is no dark color feeling in the weak state.

In this way, according to the present invention, the front half 2a
The firepower can be adjusted by freely switching between a strong state where both the front half 2b and the rear half 2b are combusted, and a weak state where only the front half 2a is combusted. The dark color feeling due to the inoperation of the portion 2b is hidden behind the front half portion 2a and cannot be seen directly from the front, thus eliminating the dark color feeling in the weak state and improving the feeling of use.
