[Chinese cabinet network] gas stove structure diagram Daquan
Gas cooker is one of the core products of kitchen and bathroom electrical products . The after-sales maintenance rate is higher than that of other kitchen and bathroom electrical products. I believe many dealers and users will have some confusion about product configuration. The following is for everyone. Maintenance structure diagram of gas cooker products for daily maintenance and maintenance reference.
How does the gas stove work?
When the gas stove is working, the gas enters the stove from the intake pipe, and is adjusted by the gas valve (the user adjusts through the knob) into the burner, and a part of the air is mixed (this part of the air is called primary air), and the mixed gas It is ejected from the fire hole of the firearm and is ignited by the ignition device to form a flame (the air required for combustion is referred to as secondary air), and these flames are used to heat the cookware placed on the pan holder.
1: Nozzle;: 2: Suction shrink tube; 3: Mix tube; 4: Dif tube.
Gas stove classification system
Ignition device: Piezoelectric ignition (ignition pin, piezoelectric ceramic, wire), and pulse ignition (battery box, pulse generator, micro switch, ignition needle, circuit).
Burner: consists of burner, nozzle, outer fire cover, air deflector and central fire cover.
Flameout protection: consists of a solenoid valve and a thermocouple.
Gas supply system: consists of a solenoid valve and a thermocouple.

Note: The position and function of the damper of the cooker
Hold the cooker by hand, there are two handle-shaped iron pieces at the burner and nozzle connection, one of which adjusts the center fire and the other adjusts the outer ring fire; they are all attached to the burner through the spring, gently dial The moving handle can adjust the size of the air inlet to change the state of the flame. When the combustion situation is not ideal, such as yellow flame, excessive flame or too small flame, or burning noise, tempering, etc., by adjusting the amount of air in the damper to achieve a better combustion situation.
Gas stove important parts function
Intake pipe: the function of connecting the gas source and the gas valve;
Valve body: responsible for opening or cutting off the gas source of the burner, responsible for turning the ignition device on or off, and regulating the output power of the burner.
Burner: The main function is to fully mix the gas with the primary air and adjust the mixing ratio of air to gas through the air deflector.
Fire cover: evenly distribute the mixture to each fire hole to enable the burner to uniformly heat the cookware;
Ignition device: The main function is to ignite the burner (the ignition mode is generally divided into two types: piezoelectric type and pulse type, the former is mostly used for desktop stoves and the latter is mostly used for embedded stoves)
Flameout protection device: It is a device to prevent gas leakage accidents when the gas stove is accidentally turned off. (These are divided into thermal induction flameout protection and ion induction flameout protection)
a. Ion induction flameout protection: the flame generates a current flow at high temperature, and a current signal is formed between the fire cover and the ignition needle. The solenoid valve is opened. When the induction needle is not burnt, the electrical signal is interrupted and the solenoid valve is closed.
Note: The most obvious feature of ion-induced flameout protection is the presence of a sensor pin in a reddish box with a ceramic body.
b. Heat-induced flameout protection: the flame raises the temperature of the thermocouple's induction head, the thermocouple induction current reaches about 100mA, the self-priming valve opens, the temperature of the thermocouple sensor head decreases when the flame is extinguished, and the induced current decreases (≥20mA). Valve closed valve.
Note: The most obvious feature of thermal induction flameout protection is the presence of a thermocouple with a red box, and the thermocouple requires brass.
The above is the main structural function description of the gas stove. Others such as knobs and panels are familiar and are not described here.
Gas stove repair common faults and treatment methods
First, no fire
(1) The main switch of the air source is not open, open the main switch of the air source
(2) The battery power is insufficient, replace the battery
(3) Ignition needle grease, cleaning ignition needle grease
(4) Improper position of the ignition needle, adjust the distance between the ignition needle and the fire cover by 4-6mm, and align with the fire hole
(5) Micro switch replacement of bad professionals
Second, leaking (or smell)
(1) The hose is ruptured or peeled off to replace or reconnect the hose
(2) The main fire of the burner is not ignited, accidentally extinguished, and then ignited after the gas is exhausted.
(3) The intake pipe seal rubber ring is aging, replace the rubber ring
Third, the flame is abnormal
(1) Red fire: high air humidity, large oil smoke, normal phenomenon
(2) Yellow fire: the damper opening is too small, open the damper
(3) There is dirt in the fire cover and the fire cover is cleaned.
(4) The liquefied gas in the cylinder is running out; replace one bottle of liquefied gas.
Fourth, from the flame, off fire (flame from the fire hole)
(1) The damper opening is too large, adjust the small damper
(2) The gas pressure is too large. When using a liquefied gas cylinder, please adjust the pressure reducing valve. Use gas pipe to turn off the gas main switch
(3) The kitchen air flows too fast, the ventilation is too strong, the small doors and windows are properly closed, and the hood is weak.
V. Tempering (burning in the burner)
(1) The fire cover is not placed, put the fire cover
(2) The gas pressure is too low. If it is to save gas, it should be opened properly and the main switch should be opened.
(3) The fire cover hole has overflowing liquid and dirt, and the fire cover is cleaned up.
(4) The burning time is too long, the temperature of the burner is too high, it is suspended, and it is used after cooling.
(5) The damper opening is too large, the sales damper
Sixth, the flame is short and weak
(1) The gas pressure is low, check whether the liquefied gas cylinder valve is open or not.
Seven, the flame is easy to extinguish
(1) The ion induction needle deviates from the flame and adjusts the ion induction needle
Eight, flame out and noisy
(1) The operation speed of shutting down the fire is too fast, and it is slower when the fire is turned off.
Nine, there is a whistle when burning
(1) The nozzle has burrs and cleans the burrs
Ten, automatic flameout
(1) Ion induction protection, the sensor pin is biased, the fire cover is placed in place, and the adjustment sensor is aimed at the quasi-fire hole.
(2) Thermoelectric protection, the thermocouple is not in the right position, adjust the small damper, adjust the thermocouple to the fire hole
(3) There is water or dirt between the induction needle and the grounding sleeve (stainless steel). Use the induction needle to contact the flame to remove water and dirt.
(4) Induction needle breaks, professional replacement
