Problems solved by technology

The existing technical solutions are caused by the production process of the timer, and the general contact resistance is tens of ohms. Since the thermocouple solenoid valve circuit is controlled by the weak current generated by the thermocouple to control the conduction of the solenoid valve, the resistance of the circuit itself is low. If it is relatively large, if you increase the resistance of the timer, the resistance of the entire circuit will increase. During the timing process, especially in the state of low fire, the gas stove is easy to shut down by itself, and the intended purpose cannot be achieved.

Abstract

The invention discloses a gas appliance, a pulse ignition device used for the same, and a pulse ignition control method, wherein the pulse ignition device used for the gas appliance comprises: a timer; an ignition switch; a solenoid valve thermocouple loop in parallel connection with the timer; and a pulse igniter respectively connected with the timer, the ignition switch, and the solenoid valve thermocouple loop. When the ignition switch is triggered, the pulse igniter controls a solenoid valve in the solenoid valve thermocouple loop to open; the timer is determined to start timing while the timing signal of the timer is detected; and the solenoid valve is controlled to close when timing ending of the timer is detected. According to the invention, through the parallel connection of the timer with the solenoid valve thermocouple loop, no automatic flame-out phenomenon occurs in the timing period when the solenoid valve thermocouple loop is normal, and thus the reliability of the timing function of the gas appliance is guaranteed.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a gas appliance, a pulse ignition device and a pulse ignition control method for the gas appliance. Background technique [0002] At present, the timing function of the existing cooker is to connect the timer in series with the thermocouple electromagnetic valve circuit. When the timer is disconnected, the gas appliance is turned off. The existing technical solutions are caused by the production process of the timer, and the general contact resistance is tens of ohms. Since the thermocouple solenoid valve circuit is controlled by the weak current generated by the thermocouple to control the conduction of the solenoid valve, the resistance of the circuit itself is low. If it is relatively large, if you increase the resistance of the timer, the resistance of the entire circuit will increase. During the timing process, especially in the state of low fire, the gas stove wi...
