look at the quality of the machine body: the appearance of the gas stove should be beautiful and generous, and there should be no collision at all parts of the machine body. Some products made of cast iron, steel plate and other materials should be painted evenly on the surface without foaming or falling off. The overall structure of the gas stove should be stable and reliable, the stove surface should be smooth and flat, without obvious warping, and the installation of parts should be firm and reliable, without loosening. Pay attention to the thickness of the steel plate on the surface of the cooker: some steel plates are thin and easy to deform and twist. Choose a safe and economical cooker: choose a cyclone fire and infrared cooker, which can save gas with relatively high heating efficiency; In addition, it is also important to have a flameout protection device. With the flameout protection device, when the flame is extinguished by wind or water, the gas can be automatically cut off to ensure safety. It is best to choose a pulse ignition cooker as the ignition mode, which has a high ignition rate. Identification of advantages and disadvantages of gas stoves: packaging and identification should be complete. The package should be marked with the name, address and model of the factory, and each cooker should have a certificate of approval and instructions for use. There should be a nameplate on the side panel of the cooker, which indicates the name, model, applicable gas and pressure, heat flow and production date, etc. Proper heat flow. The greater the heat flow value of the household gas cooker, the stronger the heating capacity, which is usually called fierce fire. Generally, consumers are willing to choose a strong fire stove. In fact, the size of heat flow should be compatible with cooking methods and stoves. The gas stove and sink must be bought before the cabinet is installed, otherwise the embedded size cannot be reserved when installing the cabinet. If the cabinet manufacturer is unwilling to help install the stove and sink, it is necessary to install the stove manufacturer, sink manufacturer and cabinet manufacturer at the same time.
