Embodiment 1

[0023] Such as figure 1 Shown is the first embodiment of the sensing device used in the flameout protection mechanism of the gas stove according to the present invention. The sensing device includes a burner 1 and a gas stove panel 2 .

[0024] in,

[0025] On the gas cooker panel 2 adjacent to the burner 1, a lighting mechanism 6 capable of detecting ultraviolet rays in the flame is arranged.

[0026] The lighting mechanism 6 includes a lighting tube 61 whose tube opening faces the burner 1 and an ultraviolet photosensitive tube 62 arranged in the lighting tube 61 .

[0027] The central line of the mouth of the lighting tube 61 is aligned with the burner 1 fire hole position. Make the maximum lighting angle of the lighting tube 61 not exceed the uppermost edge of the burner 1, avoid external ultraviolet interference, and ensure the reliability of the measurement.

[0028] In this embodiment, through the above-mentioned lighting tube 61 and the ultraviolet photosensitive t...

Embodiment 2

[0030] Such as Figure 2-Figure 7 Shown is the second embodiment of the sensing device used in the flameout protection mechanism of the gas stove according to the present invention. The difference between the sensing device of this embodiment and the first embodiment above is that:

[0031] The daylighting tube 61 includes an upper tube 611, a middle tube 612, and a lower tube 613 which are sequentially connected to form a "Z" shape structure, and an oblique first reflector is arranged at the inner corner where the upper tube 611 and the middle tube 612 are connected. 63. An oblique second reflector 64 is arranged at the inner corner where the middle cylinder 612 and the lower cylinder 613 are connected to form a periscope optical path structure. The ultraviolet photosensitive tube 62 is located in the lower cylinder 613 and faces the second reflection The mirror 64 is located on the optical path of the periscope.

[0032] The first reflection mirror 63 and the second reflec...

Abstract

The invention provides a sensing device for a flameout protection mechanism of a gas stove. The sensing device for the flameout protection mechanism of the gas stove comprises a combustor (1) and a gas stove panel (2), and is characterized in that the part, adjacent to the combustor (1), of the gas stove panel (2) is provided with a light capturing mechanism (6) capable of detecting flame ultraviolet light. Compared with the prior art, according to the sensing device, the light capturing mechanism (6) arranged on the part, adjacent to the combustor (1), of the gas stove panel (2) is capable ofdetecting the flame ultraviolet light when gas is ignited by the gas stove so as to enable the gas stove to work normally; and when accidental flameout occurs, and an ultraviolet light sensitive tube(62) in the light capturing mechanism (6) cannot detect the flame ultraviolet light, a controller directly controls an electromagnetic valve to be closed to block the gas so as to achieve the purposeof flameout protection.

Description

technical field [0001] The invention relates to the technical field of gas cookers, in particular to a sensing device that provides signals for a flameout protection mechanism of the gas cooker. Background technique [0002] At present, gas stoves are widely used in people's lives, so the safety of gas stoves has also received extensive attention. During the use of gas stoves, when the flame is extinguished by wind or boiling water overflows, it will cause gas leakage, which will cause safety accidents. Therefore, it is very necessary to introduce a flameout protection device. [0003] At present, the commonly used flameout protection devices are mainly ion flameout protection devices and thermocouple flameout protection devices. First, the ion flameout protection device requires that the induction needle must be in contact with the flame to work normally, such as the patent number ZL201220314705.7 (the announcement number is CN202675386U) The Chinese utility model patent "...
