Embodiment 1

[0026] Such as Figure 1~5 As shown, the specific implementation of the present embodiment is as follows:

[0027] A gas stove equipped with a dry-burning prevention device is composed of a dry-burning prevention device and a gas stove with a flameout protection device. The dry-burning prevention device is placed at the center of the burner of the gas stove and fixed on the gas stove. The anti-dry device includes a thermostat 1, a thermostat insulating base 2, a spring 3, an anti-dry probe body 4 and an anti-dry probe base 5; the thermostat is a bimetal thermostat, and the thermostat is connected in series Between the induction probe of the gas stove flameout protection device and the gas solenoid valve, the induction probe of the gas stove flameout protection device is matched with the flameout protection device, or a thermocouple, or an ion induction needle.

[0028] The insulating base of the thermostat is columnar, with a temperature sensor installation groove 2.1 on the ...

Embodiment 2

[0032] Such as Figure 6 As shown, the only difference between this embodiment and Embodiment 1 is that the top cover of the anti-dry probe body is an independent structure, the upper shell of the probe is integrated with the lower shell of the probe, and the top cover is connected with the upper shell of the probe. The riveting structure 4.8a is used to seal the thermostat and the insulating base of the thermostat in the main body of the anti-dry probe.

[0033] Such as Figure 7 As shown, in this embodiment, the welding structure 4.8 can also be used at the joint between the top cover and the upper shell of the probe.

[0034] In the above-mentioned embodiments, the spring installation cavity on the upper part of the anti-dry probe base and the temperature controller wire protection tube on the lower part can be a welded structure or an integrated structure; the welding structure involved on the anti-dry probe body or The riveting structure is all carried out after the ant...

Abstract

The invention discloses a gas stove equipped with an anti-dry device. The gas stove equipped with the anti-dry device is composed of an anti-dry device and a gas stove with a flame-out protection device, wherein the anti-dry device comprises a temperature controller 1, a temperature controller insulation base 2, a spring 3, an anti-dry probe main body 4 and an anti-dry probe base 5; and the temperature controller is a double-metal-sheet temperature controller, and the temperature controller is serially connected between an induction probe of the flame-out protection device and a gas electromagnetic valve. The anti-dry device disclosed by the invention is simple in structure, low in cost and reliable in working, the gas stove with the flame-out protection device can realize an anti-dry function without the need of additionally adding a control system, thus the anti-dry device can be used for both a gas stove equipped with a thermocouple flame-out protection device and a gas stove equipped with an ion probe flame-out protection device; and when a gas stove equipped with the anti-dry device disclosed by the invention has no pan placement for a long time after being ignited, a probe of the anti-dry device automatically cuts off a gas source to flame out when a temperature exceeds a set value, thus gas loss and potential safety hazards generated due to long-time no pan placement can be reduced.

Description

technical field [0001] The invention relates to a gas stove, in particular to a gas stove equipped with an anti-dry burning device. Background technique [0002] In the technical field of anti-dry burning devices for gas stoves, whether using temperature sensors, pressure sensors, or other types of sensors, it is inseparable from the need to increase the corresponding control system. [0003] For example, the "anti-dry burning gas stove electrical linkage valve" of patent No. CN200710145762.0 is provided with an anti-dry heating circuit control switch controlled by the rotation of the pressing knob, thereby realizing the purpose of anti-dry burning electrical linkage. Patent No. CN201610212613.0 "A safety device for preventing dry burning and flameout of household gas stoves" is also equipped with a circuit board. When the thermal potential disappears due to accidental flameout, or the temperature of the bottom of the dry burning pot exceeds the limit, the circuit board clos...
