How to choose a microwave oven?
(1) The brand should purchase a microwave oven that has been certified by the national safety.
(2) Type and capacity: There are many types of microwave ovens, and the output power is 500W, 600W, 800W, 1000W and so on. The capacity also has different specifications such as 0.6.0.7.0.9.1.0 ft3 (1 ft = 0.3048 m). When purchasing, you should consider the family's economic ability and population, as well as the load capacity of the home circuit and meter. As far as the living standard of 3-4 people in ordinary families is concerned, the ordinary rotary-type microwave oven with a power of 800-1000W is suitable for consideration in terms of price, capacity and power supply.
(3) Appearance quality: The selection of the appearance quality of the microwave oven should include the matching of shape, color, surface quality and parts.
(a) The shape is to see if the shape of the product is beautiful and generous.
(b) Color is to see if the color of the product is your favorite, whether the colors on the product are coordinated, and whether the product is in harmony with the color of other furniture and appliances in the placement.
(c) The surface quality is to check whether the coating, paint layer or coating on the surface of the product has mechanical scratches and scratches, whether the parts are cracked or damaged, and whether the processing peak is removed.
(d) The panel requires flatness without concavity, no rubbing, no bumps, inorganic processing marks, uniform color, good gloss, clear patterns and characters.
(4) Power-on test: Turn on the microwave oven, put in water, start the microwave oven, and observe the following points:
(a) Observe whether there is illumination in the furnace.
(b) Observe whether the glass disk in the furnace is rotating or not.
(c) Whether the water is heated, put a cup of 200 ml of cold water into a microwave oven with a power of 500 watts, start the water for 4 minutes, or put it into a microwave of 600 watts, and start the water for three minutes. It is normal to boil. If not hot, the magnetron does not work.
(d) If there is hot air exhausted, the microwave oven will be damaged if the exhaust system does not work during normal operation of the magnetron.
(e) Check that all buttons and knobs on the control panel are fully functional according to the instructions.
(f) In the middle of the microwave oven work, if the oven door is opened, the microwave oven should stop working. Otherwise, a large amount of microwaves will be harmful to people.
(g) A slight “click†sound should be heard when the door is lightly opened. This proves that the hook hook is in good contact with the micro switch.
(h) The noise should not be too large. It can be adjusted to a non-station with a medium-wave radio and placed close to the furnace. If no noise is heard, the microwave shielding is good and the microwave leakage power is small.
In addition to considering different brands, price levels, function types, and appearance differences when purchasing microwave ovens, it is likely to ignore some other important factors. It is precisely these factors that will directly affect whether you can buy a microwave oven with a high price/performance ratio. At the most affordable price, it is the pursuit of every consumer to buy a satisfactory product. Here are a few key elements that you can't ignore when buying a microwave oven, so you won't be "eye-catching" anymore.
Cabinet size ≠floor size
Consumers who choose to buy microwave ovens often value brand and capacity. It is often considered that the larger the volume, the faster the heating, ignoring the size of the bottom plate in the chassis. The industry reminds consumers that when choosing a microwave oven, we must pay attention to the size of the microwave oven floor area, because the larger the floor area, the faster the heating, the higher the heat, the more uniform the heating area. Compared to a microwave oven with a volume of 23 liters and 21 liters, the 21 liter microwave oven is more thermally efficient. Therefore, consumers must "see the essence through the phenomenon" when purchasing a microwave oven, and the size of the bottom plate cannot be ignored.
The bottom small platform has to look
A small platform protrudes from the bottom of the flat microwave oven, and there is a microwave agitator in this small platform. The microwave is dissipated by this device, so that the microwave is uniformly transported upward from the bottom, thereby heating the food in the cabinet. The larger the area of ​​the small platform, the closer the area to the bottom plate in the cabinet, the more flexible the microwave agitator will be, and the more uniform the microwave will be. If the area of ​​the small platform at the bottom of the microwave oven is small, the heating effect will be greatly reduced.
The power concept needs to be distinguished
The parameter that consumers often consider when purchasing a microwave oven is the power of the microwave oven. When choosing a microwave oven, you can't just look at the power level, depending on the output power, because the output power is the useful work of heating the food. The input power of the microwave oven is generally marked on the back of the machine. The smaller the difference between the input power and the output power, the better. The smaller the difference, the larger the effective power of the microwave oven.
The noise level is related to power consumption
The microwave oven will generate noise after a momentary start, and the noise level of the microwave oven can be heard after a few seconds of starting. If the noise at startup is comparable to the noise after a few seconds of microwave operation, the difference is not very large. It proves that the performance of the microwave oven is not very satisfactory. After starting up, it consumes too much useless power and consumes more power.
In addition, like digital cameras and mobile phones, digitally controlled microwave ovens also have "memory" problems. For example, there is a kilogram limit for hot milk, and the upper limit for different microwave ovens is different. When heating the same weight of the same food, see which machine has the shortest set-up time. The less time spent in ensuring that the food is cooked, the faster the heating of the microwave oven is proven. General microwave ovens have common functions such as hot milk, roasted chicken wings, steamed rice, etc. Customers can let the sales staff demonstrate when purchasing a microwave oven to better select a microwave oven with higher energy efficiency.
