Household gas cooker types and options

Household gas cookers have the following types according to the types of gas used, number of burners, ignition and control methods, combustion methods, functions, structural forms, baking methods, and housing materials.

Representation of domestic Gas cooker models:

According to the national standard GB16410-1996 [Household gas cookers", the method and meaning of the model formulation of domestic gas cookers in China are expressed in Chinese Pinyin letters and numbers:

1. Domestic gas cookers are represented by the Chinese Pinyin letter code JZ (stove), JH (roaster), JKZ (oven cooker), and JF (rice pot). Where J means "home."

2. The city gas category is represented by the category code in GB/T13611. R - artificial gas; T - natural gas; Y - liquefied petroleum gas.

3. The number of heads (number of eyes) is represented by numbers 1, 2, 3, and the like. The amount of rice that can be heated in the rice cooker each time is expressed as 1L, 2L, and 3L, where L indicates the unit of measurement [liter". For example: JZ12T2.........23B indicates that it is a two-head household gas stove with 12T natural gas, design number 23, and the second modification.

Household gas stoves should pay attention to the following points when purchasing:
First of all, customers must be aware of which type of gas they are using in their area of residence before purchasing it. China's urban gas is mainly divided into three categories: artificial gas, natural gas, and liquefied petroleum gas, each of which is further subdivided. Artificial gas points 5R, 6R, 7R, natural gas points 10T, 12T, 13T, can not be interchangeable with each other. Domestic gas stove products are also divided into three categories according to their applicable gas sources. Therefore, consumers must pay attention to selecting the appropriate products according to their actual gas source conditions. Should choose high-quality brand-name products, should not choose low-cost stoves. Pay attention to the manufacturer's local after-sales product.
Second, according to the family's needs to determine the installation of desktop or embedded cooker. The tabletop is a type of stove in which the entire stove is placed on the supporting surface, and the embedded name suggests that the main body of the cooker is embedded under the supporting surface. At present, commonly used desktop dual-focus stoves, ignition methods are mostly piezoelectric ceramics or electronic pulse electronic ignition, its beautiful appearance, health and durability, good combustion performance, high ignition success rate, its thermal efficiency slightly higher than the embedded stove. Two-ring fire holes can be used at the same time or separately. Generally, the thermal load of the two-ring fire holes is different, so that they can be used when different needs are needed. The high-grade gas stoves are equipped with flameout protection devices, which automatically shut off the gas source in case of accidental flameout. Some high-grade gas stoves are also equipped with a pan head overheat protection device. When an over-temperature occurs, the gas valve is controlled to shut off the gas channel, effectively preventing the accident of fire due to overheating in the pan.

Embedded gas stoves are entering large numbers of households. This is because they are luxurious and novel in appearance, easy to install, and do not occupy the space of cabinets, so they can meet the high-level needs of customers. It should be noted that if the stove is under the air, the air inlet should be set under the cabinet to facilitate the combustion of air. The biggest difference of the embedded domestic gas stoves on the market is that the material of the stove panel is relatively large, mainly stainless steel and glass. There are also some products that choose enamel, ceramics and other materials. Each material has its own advantages and disadvantages. Stainless steel materials are strong and resistant to impact, but after long-term use, the surface gloss will be worse, and the glass material is more beautiful, corrosion-resistant and wear-resistant, but its heat resistance is not as good as that of stainless steel. If it is improperly installed and used, it will lead to popping phenomenon. Ceramic panels have the advantages of the previous two products but are more expensive. Consumers can choose to purchase different materials according to their preferences.
In addition, customers need to determine how to purchase household gas stoves with different heat load values according to their own lifestyle and family members. The usual catering habits of Chinese cooking require the use of gas stoves with a relatively fierce firepower (designing a large heat load). Select the smaller firepower to save gas.
Finally, to remind our customers, according to the current effective national standards, embedded domestic gas stoves must have flameout protection safety devices, so consumers must pay attention to this when buying. Due to the special use conditions of the embedded gas stove, accidental flameout is more likely to occur during its use, and the flameout protection safety device will play a very good protection role. Be sure to note that the flameout protection device has been used for three generations during your purchase. The first generation was a memory metal protection system that was introduced around 1994. This protection system is automatically switched off by the characteristics of the memory metal. The disadvantage is that the memory metal will be gradually damaged due to the high temperature of the flame for a long time; its thermal inertia is large and it is easy to produce the action lag. It can only work more than 2 minutes after the fire is extinguished. In this time, there will be many gas leaks. relatively bigger.  The second generation is the common thermocouple flameout protection system currently on the market. This system consists of a thermocouple and a solenoid valve. When the thermocouple is heated, it generates a thermal differential potential, and the coil that enters the solenoid valve generates a magnetic field to actuate the solenoid valve. Once the flame detected by the thermocouple is extinguished, the potential generated by the thermocouple quickly drops to zero and the solenoid valve closes the gas valve under the action of the spring. When this kind of system starts to warm up for about 10 seconds, some customers find it inconvenient and unaccustomed. The flameout time is controlled at about 40 seconds, and there are still hidden dangers of gas leakage, but it is much safer than the stoves that do not have to turn off the safety protection device. The third generation is currently the most advanced ion-sensing technology. Ion-safety flame-out protection type gas stoves adopt advanced ion extinguishing protection devices. By using the conductivity of the flame, it can detect whether the flame is extinguished by the ion probe. If it goes out, the gas path is cut off immediately by controlling the solenoid valve. The response speed can reach one tenth of a second, so that no danger will occur. Such cookers are generally very quick to ignite. It should be noted that the gas stoves of the ion-sensing technology are mostly automatic ignition devices, that is, they start to ignite after the switch is pressed. If the ignition is successful, the ignition is immediately stopped. If the ignition is successful, the ignition is stopped after 8 seconds. When the semi-automatic ignition device is pressed, it will ring and stop. The stoves in the general shopping mall are not connected to the air, so you can tell whether the stove is fully automatic by pressing it and then dropping it. In addition, ion-sensing cooker ignition devices and flameout protection devices generally require a No. 1 battery to supply power, so this type of stove usually has two No. 1 batteries installed. The ordinary cooker only needs one battery.
The new mandatory national standards for "home gas cookers" formulated by the China Hardware Association and the China Standardization Association are expected to be implemented from the beginning of 2006. According to the new standard, any stoves (including tabletop stoves) that fail to install the flameout protection device in accordance with the new standard will not be allowed to be manufactured or sold in the future. Therefore, customers will have an additional layer of security in use.
