Abstract

The invention provides an air guide structure and a range hood. The air guide structure comprises air guide plates and concave-convex structures, wherein the concave-convex structures are used for changing the air inlet frequency of the air guide plates and arranged on the surfaces of the sides, facing an air inlet of a panel of the range hood, of the air guide plates. The concave-convex structures used for changing the air inlet frequency of the air guide plates are arranged on the air guide plates, so that a certain time difference exists when air passes through the concave-convex structures on the air guide plates, differentiation of air speeds is enhanced, meanwhile, the inherent frequency of the air guide structure is changed, and the air inlet area is increased. Accordingly, a squeaking phenomenon of the air guide structure, namely the whole range hood is eliminated by means of a frequency balancing method, and the operation reliability of the range hood is improved.

Description

technical field [0001] The invention relates to the technical field of cooking equipment, in particular to an air guide structure and a range hood. Background technique [0002] At present, the way of absorbing the oil fume of the range hoods on the market is generally that the oil fume enters the oil net through the air deflector and then enters the air duct system. When the area of ​​the air inlet of the panel is small, and the wind speed of the air inlet reaches a certain level, the whole machine will produce abnormal sound or howling. [0003] After long-term research by the inventor, it can be determined that this howling phenomenon is due to the negative impact of the uniformly generated wind speed at the wind deflector reaching the natural frequency of the material under high wind speed conditions. It can be seen that in order to solve the howling problem, the frequency equalization method can be used to change the wind speed at the air inlet to eliminate the howling...
