Embodiment 1

[0037] Such as figure 1 As shown, the embodiment of the present invention provides a gas cooker, which includes a solenoid valve 7, a controller 6, a thermocouple sensing device 4 and a flame detection device.

[0038] In the embodiment of the present invention, the controller 6 is electrically connected to the solenoid valve 7 , and the thermocouple sensing device 4 is arranged on the burner of the gas stove and is electrically connected to the solenoid valve 7 . The flame detection device is also arranged on the burner of the gas range, and is electrically connected with the controller 6 .

[0039]The burner includes a base 1, a central fire cover 2 and an outer ring fire cover 3. The thermocouple sensing device 4 is arranged on the base 1 , and the head of the thermocouple sensing device 4 is close to the fire hole of the central fire cover 2 . The flame detection device can be a photosensitive sensor 5 , which is relatively arranged on the burner, and the photosensitive ...

Embodiment 2

[0043] Such as figure 2 As shown, the embodiment of the present invention provides a control method of a gas cooker, the control method is applied to the gas cooker of any of the above embodiments, and the gas cooker specifically includes the following control steps:

[0044] S1. Obtain the electrical signal of the thermocouple sensing device 4;

[0045] The thermocouple induction device 4 is composed of two different metals, and forms a loop with the corresponding wires. The flame burns the induction head to cause a temperature difference between the two metals, and then generates electromotive force and current, thereby maintaining the connection with it. The electromagnetic valve 7 opens the valve, and the electromagnetic valve 7 is arranged on the gas pipeline of the gas cooker, and is used for controlling the opening and closing of the gas pipeline. The higher the temperature, the higher the voltage and the greater the current. When the flame disappears or becomes smal...

Embodiment 3

[0073] The embodiment of the present invention also provides a control device for a gas stove, the control device includes:

[0074] The first acquisition module is configured to acquire the electrical signal of the thermocouple sensing device 4; for details, refer to step S1 of the above-mentioned embodiment, which will not be repeated in this embodiment;

[0075] The second acquisition module is configured to acquire the detection signal of the flame detection device when the electrical signal is less than a preset threshold; for details, refer to step S2 of the above-mentioned embodiment, which will not be repeated in this embodiment;

[0076] A processing module, configured to judge whether there is a flame in the gas cooker according to the detection signal; for details, refer to step S3 in the above embodiment, which will not be repeated in this embodiment;

[0077] The first control module is configured to provide the solenoid valve 7 with a valve maintenance signal to ...

Abstract

The invention discloses a gas stove as well as a control method and a control device of the gas stove. The control method includes the following steps that an electric signal of a thermocouple induction device is acquired; when the electric signal is smaller than a preset threshold value, a detection signal of a flame detection device is acquired; whether a flame exists in the gas stove is judgedaccording to the detection signal; and when the flame exists in the gas stove, a valve maintaining signal for maintaining the opening state is provided for an electromagnetic valve. Due to the arrangement, gas can be led into a fire hole through the electromagnetic valve, normal working of the gas stove can be guaranteed, and then accidental flameout of the gas electromagnetic valve can be prevented. The flame detection capability of a flameout protection device of the gas stove is improved, the sensitivity is improved, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of gas stoves, in particular to a gas stove, a control method and a control device for the gas stove. Background technique [0002] With the improvement of people's living standards, many intelligent household appliances have gradually entered people's lives. Now people mostly use gas stoves for cooking. When the gas stove is working, the gas enters the stove from the intake pipe, enters the base through the adjustment of the gas solenoid valve, and mixes part of the air at the same time. These mixed gases are sprayed from the fire hole of the fire distributor. At the same time, it is ignited by the ignition device to form a flame, which is used to heat the cooker placed on the rack. [0003] At present, the gas cooker is usually provided with a thermocouple sensing needle, and the thermocouple sensing needle is located at the fire hole for sensing whether there is a flame at the fire hole. When there is a...
