Embodiment Construction

[0033] figure 1 Shown is a first embodiment of a gas cooker according to the invention. The gas stove includes a plug valve 1 , a current-driven valve 2 , a burner 3 , an igniter 4 , a control system 51 , a flame detection device 6 , and a trigger switch 7 . In this embodiment, the plug valve 1 has a control knob and a valve stem, wherein the operation knob can be pressed and rotated by the user to control the igniter 4 to ignite the burner 3 and adjust the size of the flame of the burner 3 . The current-driven valve 2 can be a solenoid valve well known to those skilled in the art, that is, by applying current to the coil wound on the solenoid valve body to generate a magnetic field, thereby driving the magnetic core 21 to overcome the spring force and keep the solenoid valve open. In this embodiment, the solenoid valve 2 is a double-coil type, which includes a first coil 22 electrically connected to the control system 51 and a second coil 23 electrically connected to the fla...

Abstract

The invention discloses a gas stove, comprising a plug valve, a current drive valve, a burner, an igniter and a control system, wherein the control system comprises a first switch, a second switch and a timer. The first switch is used for controlling current supplied to the current drive valve so as to keep the current drive valve in the active state, the second switch is used for controlling the current supplied to the current drive valve so as to keep the current drive valve in the active state, and the timer is electrically connected with the first switch and the second switch and is used for controlling the first switch and the second switch to keep conduction for a certain period of time after the plug valve is operated. A multistage control circuit of the current drive valve is provided, and the rest of switches and timers also can close the current drive valve in the preset period of time although short circuit happens when a switch or a timer in one stage of control circuit has fault, thereby largely reducing the probability that the fuel gas is leaked to cause security incident due to the element fault.

Description

technical field [0001] The present invention relates to a control system, in particular to a control system capable of driving a solenoid valve and keeping it open after the operating knob is pressed down. [0002] The present invention also relates to a gas stove using the above-mentioned control system. Background technique [0003] Along with popularizing of household gas stove, the use safety of household gas stove is also paid more and more attention to. Existing gas stoves all include a flameout protection device, which is a device for automatically cutting off the gas when the flame is extinguished due to accidents such as wind blowing or boiling water overflowing during the use of the gas stove. The application of the flameout protection device has greatly improved the use safety of the gas stove. Currently, the thermoelectric flameout protection device is commonly used. Its structure is that the electromagnetic valve is installed in the gas circuit structure of th...
