Problems solved by technology

However, when the amount of gas supplied to the burner is suddenly reduced by closing the solenoid valve serving as the control valve, the primary air supplied to the burner will not be drastically reduced under the influence of inertia, so it is easy to cause excessive air in an instant. The burner is misfiring, so the minimum gas volume cannot be set too low

Embodiment Construction

[0021] refer to figure 1 , 1 is a top plate which covers the upper surface of the oven main body which is not shown in figure. The burner opening 1a is provided in the top plate 1, and the burner 2 is provided in the stove main body so that it may face the burner opening 1a. On the top plate 1, a fire prop 3 is arranged to surround the burner 2, and the fire prop 3 is formed by radially installing a plurality of fire prop claws 32 on the ring-shaped fire prop frame 31, and is placed on the Cooking containers such as pots on the fire support 3 are heated by the burner 2 .

[0022] The burner 2 consists of a known annular burner having an annular burner body 22 connected to a mixing tube 21, placed on the burner body 22 and formed between it and the burner body 22 The annular burner cover 23 of the flame outlet 23 a, the annular secondary air guide plate 24 placed on the burner cover 23 and forming a secondary air passage between it and the burner cover 23 . In addition, an i...

Abstract

The invention provides a gas cooker. The gas cooker is provided with a pot bottom temperature sensor. A gas supply path for supplying the gas to a burner is provided with a control valve and a throttle hole connected with the control valve in parallel. The control valve is closed when the sensor detection temperature is above the upper limit temperature of the specified setting temperature ranges and is opened when the sensor detection temperature is below the lower limit temperature of the specific temperature ranges. The gas cooker can reduce power consumption of the control valve, and the smallest gas volume specified by the throttle hole can be set to be as small as possible to improve the temperature adjusting performance. The control valve is formed by an electrodynamic type diaphragm valve. The electrodynamic type diaphragm valve comprises a valve shell, a diaphragm, a valve body portion, a motor and a feeding lead screw mechanism, wherein the valve shell is internally provided with a valve chamber and a valve seat arranged on an end wall of one end of the valve chamber, the diaphragm is installed on the end face of the other end side of the valve chamber, the valve body portion is arranged on the diaphragm and opposite to the valve seat, and the diaphragm can be deflected by the forward rotation and reverse rotation of the motor to enable the valve body portion to be close to or away from the valve seat.

Description

technical field [0001] The present invention relates to a gas stove having a burner for heating a cooking vessel placed on a fire stand on a top plate and a bottom temperature sensor for detecting the temperature of the cooking vessel. Background technique [0002] So far, such a gas stove has been known as a gas stove (for example, refer to Patent Document 1): in order to perform temperature regulation control to maintain the temperature of the cooking container within a predetermined set temperature range, the gas stove is turned on to the combustion chamber. A control valve and an orifice connected in parallel with the control valve are set on the gas supply road for the gas appliance to supply gas. Turns on when the detected temperature falls below the lower limit temperature of the set temperature range. With this gas stove, when the temperature detected by the pan bottom temperature sensor exceeds the upper limit temperature, the amount of gas supplied to the burner i...
