Problems solved by technology

It can be seen that there are two major drawbacks in the existing gas valve technology: first, the safety valve and the flow control valve are set separately, which not only increases the manufacturing cost, but also the control accuracy is not high; second, the control of the existing gas valve is still mechanical Control is the main focus.

Embodiment 1

[0029] Such as Figures 1 to 4 As shown, the present invention provides a gas valve device. The gas valve device includes a gas inlet 1, a main control solenoid valve 3, a first gas mixing chamber 5, a control module 4, and a first solenoid valve 6 arranged between the main control solenoid valve 3 and the first gas mixing chamber 5, The gas inlet 1 communicates with the main gas pipe 2 . The first air mixing chamber 5 is used to supply air to the burner. Specifically, the first gas mixing chamber 5 delivers the gas to the Venturi mixing tube, and the Venturi mixing tube mixes the gas with air and then transmits it to the burner. The control module 4 is used for controlling the main control solenoid valve 3 and the first solenoid valve 6 .

[0030] When the main control solenoid valve 3 is opened, gas flows to the first solenoid valve 6 through the main control solenoid valve 3; when the main control solenoid valve 3 is closed, gas cannot flow to the first solenoid valve 6 ...

Embodiment 2

[0036] This embodiment is improved on the basis of Embodiment 1. Compared with Embodiment 1, this embodiment adds a second air-mixing chamber 14 and a second solenoid valve 15 arranged between the main control solenoid valve 3 and the second air-mixing chamber 14 . The first air mixing chamber 5 is used to supply air to the central small flame cover of the burner. The second air mixing chamber 14 is used to supply air to the outer ring fire cover of the burner. When the main control solenoid valve 3 is opened, gas flows to the second solenoid valve 15 through the main control solenoid valve 3; when the main control solenoid valve 3 is closed, gas cannot flow to the second solenoid valve 15 through the main control solenoid valve 3. The second solenoid valve 15 is used to control whether the gas flowing through the main control solenoid valve 3 flows to the second gas mixing chamber 14 and the flow rate. The control module 4 is also used to control the second solenoid valve 1...

Embodiment 3

[0040] This embodiment is improved on the basis of Embodiment 1. The main control solenoid valve in this embodiment includes a valve core, a spring and an electromagnet. The electromagnetic coil of the electromagnet is connected with the thermocouple, and the electromagnetic coil of the electromagnet is also connected with the control module. That is to say, the electromagnetic coil of the electromagnet is connected with the thermocouple and the control module at the same time. The control module is used to control the magnitude and direction and duration of the current flowing to the electromagnetic coil of the electromagnet. The spool is magnetic and fixed magnetically. Because the control module can control the flow direction of the current flowing to the electromagnetic coil of the electromagnet, the magnetism of the electromagnet can be changed, which can generate attraction to the spool and repulsion to the spool. Furthermore, this embodiment can also conveniently rea...

Abstract

The invention provides a gas valve device, which comprises a gas inlet, a master-control electromagnetic valve, a first gas mixing cavity, a control module, and a first electromagnetic valve arranged between the master-control electromagnetic valve and the first gas mixing cavity, wherein the gas inlet is communicated with a main gas pipe; the first gas mixing cavity is used for supplying gas to a burner; when the master-control electromagnetic valve is opened, the gas can pass through the master-control electromagnetic valve to flow to the first electromagnetic valve; when the master-control electromagnetic valve is closed, the gas cannot pass through the master-control electromagnetic valve to flow to the first electromagnetic valve; the first electromagnetic valve is used for controlling whether the gas passing through the master-control electromagnetic valve flows to the first gas mixing cavity and/or controlling the flow velocity of the gas; and the control module is used for controlling the master-control electromagnetic valve and the first electromagnetic valve. Therefore, mechanical or half-mechanical gas control modes always adopted in the field of gas stoves are changed, and the intelligent control degree for the gas is improved.

Description

【Technical field】 [0001] The invention relates to the field of cookers and cooker parts, in particular to a gas valve device and a gas cooker. 【Background technique】 [0002] Existing gas valves include flow control valves and safety valves. When in use, the flow control valve and the safety valve must be turned on at the same time to ignite the gas cooker. Most of the current safety valves use electromagnetic spools, which are installed at the rear end of the flow control valve. When opening the flow control valve, the rotating shaft must be pressed down and then rotated to open the flow control valve. At the same time, the cam mounted on the rotating shaft rotates, and the solenoid valve is pushed open by the push rod. It can be seen that there are two major drawbacks in the existing gas valve technology: first, the safety valve and the flow control valve are set separately, which not only increases the manufacturing cost, but also the control accuracy is not high; seco...
