Range hood and control method thereof

Abstract

The invention discloses a range hood, which comprises a smoke collecting hood and a smoke guide plate assembly. A smoke collecting cavity is formed in the smoke collecting hood, and the bottom of the smoke collecting cavity is open, and the smoke guiding plate assembly includes A smoke guide plate and two baffles, one of which is at least partly located on the left side of the smoke guide plate, and the other baffle plate is at least partially located on the right side of the smoke guide plate, characterized in that the smoke guide plate can be in the first position, at this time The smoke guide plate is located in the middle of the bottom of the smoke collecting chamber, and the smoke guide plate can also be in the second position, at this time, the smoke guide plate is located under the smoke collecting chamber; each baffle can be in the third position, and at this time, the baffle plate The left or right side of the bottom of the smoke hood extends to the middle of the upper surface of the smoke guide plate; each baffle plate can also be in the fourth position, and at this time the baffle plate is overturned and separated from the smoke guide plate. Also disclosed is a control method for the above range hood.

Description

Technical field [0001] The present invention relates to a hood purification apparatus, in particular a suction hood, and a control method of the smoke hood. Background technique [0002] Swebed hood has become an indispensable kitchen home appliance equipment in modern families. The suction hood is to operate using fluid kinetic principles, and the cigarette fans are filtered through the centrifugal fan inside the suction hood, and some grease particles are filtered. The centrifugal fan includes a volute, an electric machine mounted in a volute of the impeller and a rotating impeller. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the fans below the suction hood are sucked into the fan. After the fan accelerates, it is collected by the volute, and the guide is discharged. [0003] Usually the suction hood includes a top-absorbing and side suction, and the top-eye of the eye-catching hood is made in the advantages of clean and lig...

AI Technical Summary

Problems solved by technology

[0005] 1) After the range hood is installed with the cabinet, there will be a large gap between the cabinet and the fume collecting hood. This gap will make it easy for the oil fume to escape from here, and at the same time, the oil will condense on the cabinet;

[0006] 2) At present, commercial housing in the market is basically a public flue. In order to prevent the backflow of oil fume from the public flue, the range hood usually needs to be additionally installed with a check valve, resulting in a more complicated structure;

[0007] 3) At present, it is difficult for range hoods on the market to realize that the air inlet of the range hood is in the golden smoking area when cooking on one side or when the fire is large or small, or the smoke collecting hood is too small to effectively collect the smoke, which will cause smoke to escape when the user cooks with a large amount of oil fume. thereby affecting the user's health
