Gas valve device and gas stove

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...

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. On the one hand, the degree of intelligent control is not high, which cannot meet the user's refined use needs. On the other hand, the mechanical or semi-mechanical control mode is easy to cause wear and tear, which affects the control accuracy and sensitivity and reduces the service life. At the same time, there are also potential safety hazards of air leakage.
