The hood failure rate is extremely high. The purchase should be based on the four major indicators.

The range hood is our kitchen appliance with very high usage rate. With the development of new technology, the hood is developing in the direction of intelligence and humanity, both in appearance and function. Such important home appliances have been repeatedly exposed to unacceptable rates, which inevitably worries consumers. Nowadays, there are more and more types of range hoods on the market. Consumers should think rationally. When buying, remember not to be fooled by advertisements. It is the key to see the following four indicators.

The hood operating noise threshold is 70dB

In China, the noise of the product of the range hood should not exceed 70 decibels. This indicator can be measured by testing the range hood at the time of purchase. The high-quality hood has a stable motor running during operation, and the assembly of the product is also tightly combined, so there is no large working noise and the whole operation is smooth.

The hood airflow threshold is 17m3/min

Generally speaking, the larger the motor power, the larger the exhaust air volume, and the more the amount of soot discharged, but as the exhaust air volume increases, the working noise of the product will also increase, when the air volume of the range hood exceeds At 15m3/min, it is not helpful to continue to increase the air volume to improve the smoke exhausting effect, so 17m3/min is the smoke exhausting threshold of the range hood.

Grease separation is not less than 80%

The grease separation of the hood directly affects the key indicators of the degree of soot accumulation inside the machine. When cooking, the fumes will not only be discharged outside the flue, but more oil will be hidden inside the machine and finally into the oil tank. The grease separation is an important indicator to measure the separation ability of the oil inside the machine. The higher the degree of separation, the less grease will accumulate inside the machine.

The first-level energy efficiency total pressure efficiency should be greater than 25%

The first-level energy efficiency requirement is greater than or equal to 25%, which is an indicator of the comprehensive performance consideration of the hood. The full-pressure efficiency refers to the ratio of the output power of the hood motor to the power carried by the hood's exhaust air volume, that is, the more full-pressure efficiency High, the efficiency of the exhaust fumes is higher. Generally, the primary energy efficiency should be greater than 25%, and the minimum can not be lower than 11%. Source: Home Grid
