1, food cooking appliances: gas-electric integrated stove, microwave oven, induction cooker, oven, air fryer, electric pressure cooker, electric baking pan, toaster, electric steamer, electric grill, coffee machine, etc. 2. Food preparation utensils: electric cutting machine, vegetable washer, meat grinder, fruit and vegetable peeler, egg beater and bread maker. 3. Food preparation equipment: planer, yogurt machine, ice cream machine. 4. Kitchen sanitary appliances: dishwasher, ultraviolet sterilizer, range hood, water purifier and garbage disposal. 5. Storage appliances: disinfection cabinets, refrigerators, etc. 1, range hood: smoke exhaust effect, convenient cleaning As an essential cleaning tool in the kitchen, the smoke exhaust effect of range hood must be the first consideration for consumers when purchasing. In addition, the cleaning of range hoods has always been a difficult problem for consumers. No matter how good the range hood is, no matter how advertised, it is free of oil, disassembly and washing. Because there is no oil fume purification device and purification process, it will inevitably be polluted by oil fume. At present, many users report that the smoke exhaust effect and noise of the newly bought range hood are normal at first, but after running for a period of time, the noise increases and the exhaust air volume decreases. This is mainly because the turbine blade of the range hood fan is adhered by condensed oil dirt, which destroys the dynamic balance of the fan blade over time, not only increases the resistance and noise of the fan bearing, but also affects its life. Therefore, the cleaning of range hoods is the most important work in daily maintenance after purchase. At the same time, we should also carefully observe that there should be no seams on the surface of the smoke collecting hood of the range hood (it is best to stretch it as a whole without leaving dead ends) so as to clean it more thoroughly and conveniently. 2, gas stove: large firepower is not necessarily a good stove. In the minds of many consumers, there is such a misunderstanding: the greater the firepower, the better the gas stove. In view of this psychological misunderstanding, some businesses began to publicize their products' high efficiency and energy saving. However, the greater the firepower, the greater the gas consumption per unit time, so the so-called argument of large firepower and energy saving is untenable. 3. How to choose forced exhaust water heater for water heater: Forced exhaust or forced blast is used to exhaust the combustion smoke to the outside, effectively avoiding CO poisoning. The safety performance is more perfect and the installation is relatively simple. 4. How to choose the number of liters of gas water heater "liter" of gas water heater refers to its hot water flow per minute, which can be simply understood as the amount of hot water that meets the corresponding conditions per minute. The greater the rise, the more hot water can be provided per unit time, and the more places where hot water can be used. The number of bathrooms also directly affects this standard. There are many bathrooms, so there is a great chance to use water at the same time. If it is a double bathroom, it is best to use 16 liter gas water heater. Another important parameter is the distance between the gas water heater and the water use place. The farther the distance, the greater the number of liters needed. Because there will be a lot of heat loss in the process of water delivery, this loss also needs faster heating to make up.
