Kitchen ventilator

Abstract

The invention discloses a kitchen ventilator. The kitchen ventilator comprises a main kitchen ventilator body, an opened smoke cavity is formed in the main kitchen ventilator body, a frame is aslant and movably installed in the opening of the smoke cavity to seal the opening, and a separating net internally provided with an installation hole is installed in the frame. A heater is arranged in the installation hole, an exhaust passage communicating with the smoke cavity is formed in the main kitchen ventilator body, and a draught fan used for air drafting and a purification assembly are arrangedin the exhaust passage. The purification assembly comprises an ozone generator, an air case and a negative ion assembly, wherein indoor smoke enters the smoke cavity through the heated separating netunder the effect of suction force of the draught fan, and then discharged out of the exhaust passage after passing through the ozone generator, the air case and the negative ion assembly. Compared with the prior art, the kitchen ventilator has a higher capability of smoke purification. Moreover, the cleaning period of the separating net is longer, the cleaning pressure of users is alleviated, andit is more convenient for the users to use the kitchen ventilator.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood for removing oil smoke pollution. Background technique [0002] The range hood is a kind of equipment used today to discharge indoor oil fume, but indoor oil fume actually contains odor pollution, solid particle pollution and oil pollution. The direct discharge of these pollutants to the outside will cause damage to the atmosphere. For this reason, someone has designed a way to install an activated carbon filter element in the range hood to purify the pollution. However, the problem with the activated carbon filter element is that all pollution will be absorbed by the activated carbon and accumulate in the air. In the activated carbon, the activated carbon is very easy to clog and needs to be replaced frequently, which is not very practical. For this reason, in order to reduce the pressure of activated carbon, some people install a fume separation screen at the inlet of t...

The direct discharge of these pollutants to the outside will cause damage to the atmosphere. For this reason, someone has designed a way to install an activated carbon filter element in the range hood to purify the pollution. However, the problem with the activated carbon filter element is that all pollution will be absorbed by the activated carbon and accumulate in the air. In the activated carbon, the activated carbon is very easy to clog and needs to be replaced frequently, which is not very practical

For this reason, in order to reduce the pressure of activated carbon, some people install a fume separation screen at the inlet of the range hood to filter out part of the oil. However, there is still a disadvantage of using the separation screen, that is, because the oil has a certain adhesion, it does not It will slide off from the separation net immediately. It needs to accumulate a certain weight and then slide off when the gravity is greater than the adhesion. This causes the oil to condense and form oil stains on the separation net after cooling, which requires frequent cleaning. Remove the separation screen for cleaning, and it does not solve the problem of needing to replace the activated carbon frequently
