AI Technical Summary

Problems solved by technology

[0004] Due to the uniform distribution of the oil screen, most of the airflow passes through the middle part near the air inlet, and the negative pressure in the middle part is relatively large, while the negative pressure on both sides is low. Since the oil screen is fixed during the working process of the range hood, In the case of a single stove or two stoves with different oil fume concentrations, it is impossible to maximize the use of fan performance

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] see Figure 1 ~ Figure 4 , a range hood is a side suction range hood, comprising a housing 1 and a panel 2 arranged on the front side of the housing 1, the panel 2 gradually tilts backward from top to bottom. For the convenience of description, in this specification, "front", "rear", "left", "right", "up", and "down" refer to the direction of the range hood relative to the user when in use.

[0034] An air inlet 21 is opened on the panel 2, and the air inlet 21 extends laterally in the left and right direction, and a grid-like oil screen assembly 3 is arranged at the air inlet 21. The oil screen assembly 3 includes a frame 31 and at least two blades 32 arranged in the frame 31 , and each blade 32 is arranged at intervals in the left and right directions, thereby forming a grid shape. The upper and lower ends of each blade 32 are rotat...

Abstract

The invention discloses a range hood, which comprises a casing and a panel arranged on the front side of the casing, an air inlet is opened on the panel, an oil screen assembly is arranged at the air inlet, and the oil screen assembly includes a frame and at least two blades arranged in the frame, the blades are arranged at intervals in the left and right directions, and it is characterized in that: the upper and lower ends of each blade are respectively connected to the frame through a rotating shaft to turn over relative to the frame, the blades, the rotating shaft Both extend longitudinally. Also disclosed is a control method for the above range hood. Compared with the prior art, the present invention has the advantages that: by setting the smoke-guiding blades to be relatively rotatable, the direction of suction can be distributed to a position where the concentration of oil fume is relatively high; The difference between two sensors is used to automatically control the flipping of the blades to maintain the best oil suction effect in real time.

Description

technical field [0001] The invention relates to a cooking fume purification device, in particular to a range hood and a control method for the range hood. Background technique [0002] Along with the improvement of living standard, the raising of the requirement of quality of life, range hood is used widely in each family as the important electric appliance that sucks the lampblack that produces when cooking in the family kitchen. The main problem at present is that when the range hood is working, the oil fume passing through the air duct tends to accumulate a large amount of oil in the air duct. Due to the high viscosity of the formed oil, it is difficult to discharge from the air outlet of the air duct, causing oil pollution to the pipeline. The corrosion of the range hood reduces the service life of the range hood and increases the use and maintenance costs of the range hood, while the other part is directly discharged. The range hood contains a large number of carcinogen...
