Control system for commercial gas cooker

Abstract

The utility model discloses a control system for a commercial gas cooker. The commercial gas cooker comprises a blower for purging a hearth of the commercial gas cooker, and an igniter used for igniting. The control system for the commercial gas cooker is characterized by comprising an intense-fire solenoid valve, a weak-fire solenoid valve, a gas pressure switch, a gas leakage detector and a program controller, wherein the program controller is used for controlling all the components of the control system as well as the blower and the igniter according to the preset program and detecting the flame and all the components of the control system. The phenomenon of detonation in the closed hearth due to certain reasons is avoided; and whether the pressure of the gas source is controlled in the specified range or not and whether the gas cooker has the phenomenon of electric leakage or not are simultaneously monitored, so that the safety in use of the gas cooker is enhanced, the gas cooker is convenient to maintain, and when the system is abnormal, the gas source is cut off during the warning process, and meanwhile, the fault part is displayed.

Description

technical field [0001] The invention relates to a control system, in particular to a commercial gas stove control system. Background technique [0002] With the widespread use of gas, accidents caused by operation and equipment in the use of gas appliances tend to increase, and the safety of gas appliances should be highly valued. [0003] When the combustion chamber is relatively closed, such as large pots, steamers, etc., it may cause deflagration under the following conditions: [0004] 1. The valve is not closed tightly or the valve leaks; [0005] 2. Failure to ignite for many times; [0006] 3. The ignition burner goes out, [0007] 4. When the gas supply pressure is unstable or the gas stops suddenly (such as when the gasification capacity of the liquefied petroleum gas cylinder is insufficient, the cylinder is full and the residual liquid is present), the flame will be extinguished, resulting in a large amount of gas leakage. [0008] These situations lead to the...

Problems solved by technology

[0007] 4. When the gas supply pressure is unstable or the gas stops suddenly (such as when the gasification capacity of the liquefied petroleum gas cylinder is insufficient, the cylinder is full and the residual liquid is present), the flame will be extinguished, resulting in a large amount of gas leakage

[0008] These situations lead to the accumulation of gas in the combustion chamber, and when it encounters an ignition source, deflagration occurs, and the consequences are more serious.

[0009] When the existing commercial gas stove control system generally adopts the thermocouple method, the relevant standards stipulate that the valve closing time is within 50s, and the gas leaked during this period is enough to cause danger.
