Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of range hood, specifically to smoke baffle assembly, range hood and kitchen system. BACKGROUND

[0002] The main function of the oil fume exhauster is to suck oil fume, and the main function of the fan part is to circulate air flow in the kitchen room to reduce temperature. The fan part blows high-speed air flow to the cooking personnel to reduce the temperature of the head and upper limbs of the cooking personnel. The fan needs to be used in the high-oil and high-salt environment of the kitchen. When the fan is not used, how to ensure that oil fume and stains cannot enter the air duct from the air outlet to pollute the fan blade is a difficult problem. The current solution is to make the air outlet a glass panel that can be opened and closed. When the fan is used, the glass panel is opened to expose the air outlet to send air. When the fan is closed, the glass panel is closed to form a closed state of the air duct, thereby achieving the effect of preventing pollution.

[0003] The existing glass panel opening and closing adopts 6 connecting rods and 16 rotating pairs to transmit power to realize the lifting and sliding opening and closing of the glass panel. However, this structure is extremely complex, and it is difficult to produce and assemble.
