Low-noise oil smoke extracting device capable of balancing air flow and oil stain cleaning method

Abstract

The invention discloses a low-noise oil smoke extracting device capable of balancing air flow and an oil stain cleaning method. The low-noise oil smoke extracting device comprises an oil smoke guider and a fan, wherein an air inlet and an air outlet are formed in a shell of the oil smoke guider; an air outlet channel is formed in the shell; the air outlet is communicated with the air outlet channel; at least one air hole is formed in the front end surface of the shell; the air outlet channel extends forwards to be near the air hole; the air outlet and the fan are connected through an oil smoke outlet pipeline; the air inlet is connected with an air input pipeline; and the oil smoke guider is arranged at the rear side of a cooking range. According to the low-noise oil smoke extracting device, an air outlet device and an air inlet device are simultaneously arranged on an extractor hood, and therefore, when the upper end of the shell of the extractor hood exhausts air, the lower end of the shell of the extractor hood can immediately supply air to the environment around the cooking range so as to avoid the formation of a negative pressure state of the environment around the cooking rang and consequently oil smoke drifting does not happen; oil smoke can be completely exhausted to clean just by adopting the fan with low rotation speed, big blades and small power; air power noise can not be generated by the fan; and therefore, the noise of the extractor hood caused by the fan is lowered greatly.

Description

technical field [0001] The invention relates to the technical field of kitchen utensils, in particular to a low-noise oil suction device for balancing air flow and a method for removing oil stains. Background technique [0002] Range hoods are essential kitchen equipment for modern families. The dietary structure of the Chinese is very different from that of the Westerners. The Chinese pay attention to gourmet food, and frying, frying, cooking and deep-frying account for a large proportion in food processing. It is greasy and not easy to clean, so the range hood has become an indispensable equipment. By using the range hood, it can reduce the pollution of the cooking fume to the kitchen environment and the damage to human health. [0003] The core component of the range hood in the prior art is a centrifugal fan. The high-speed fan discharges the air in the wheel housing of the range hood in one direction, resulting in a relative vacuum inside the wheel housing and forming ...

AI Technical Summary

Problems solved by technology

For range hoods, air volume and noise are a pair of contradictions that are difficult to reconcile. The greater the air volume, the greater the accompanying noise. In order to absorb the oil fume faster, range hood products often use high-speed, small impellers, and multiple Centrifugal fans with blades, and the suction port on the range hood is too small, which causes negative effects such as increased aerodynamic noise and energy consumption, and because the distance between the range hood and the stove is too far, the exhaust air volume When the amount of oil fume and exhaust gas is greater than that produced, it may fall into a vacuum pumping state, resulting in a negative pressure state in the use environment. This negative pressure environment not only restricts the function of the range hood, causes the oil fume to drift, and the suction rate is very low. At the same time, it brings potential danger to the use environment

The indoor noise and negative pressure brought by the large air volume have far exceeded the range that people can bear. There are many users who would rather bear the smoke and fire than use the range hood
