Damping and noise-reducing device of air conditioner outdoor unit

Abstract

The invention discloses a damping and noise-reducing device of an air conditioner outdoor unit. The damping and noise-reducing device comprises an air conditioner outdoor fan, wherein a q-shaped guide tube is arranged at the rear end of the air conditioner outdoor fan, the lower end of the q-shaped guide tube is connected with a U-shaped guide tube, the other end of the U-shaped guide tube is connected with an inverted L-shaped guide tube; diffusion plates are respectively arranged on joints among the U-shaped guide tube, the q-shaped guide tube and the inverted L-shaped guide tube; and corresponding convex lug structures are respectively arranged on the joint of the q-shaped guide tube and the U-shaped guide tube and the joint of the U-shaped guide tube and the inverted L-shaped guide tube. The damping and noise-reducing device has the beneficial effects that the gas flow noises are lowered by lengthening a gas flow path, gas flow can be homogenized and the noises can be lowered by arranging the diffusion plates in the gas flow guide pipeline, the whole damping and noise-reducing device is arranged behind the fan of the whole outdoor unit for regulating the gravity center of the air conditioner outdoor unit to be close to the geometric gravity center and lowering the vibration of the outdoor unit.

Description

technical field [0001] The invention relates to a shock and noise reduction device, in particular to a shock and noise reduction device for an outdoor unit of an air conditioner. Background technique [0002] Due to the widespread use of household air conditioners, everyone has paid attention to the impact of noise on the environment and the use of rooms, and the noise generated during its operation has become one of the important indicators affecting user comfort. Especially in summer is the peak period of air conditioner use, if the sound value of the outdoor unit is too high, it will affect the rest of users and others, and in severe cases, it will cause complaints, effectively reduce the noise value of outdoor air conditioners, so that the surrounding environment can meet the required environmental standards , It has very important social significance to improve people's quality of life and create a quiet living environment, so we must make great efforts to study the noi...

Problems solved by technology

[0003] At present, the large impact of the noise source transmission of the outdoor unit of the air conditioner is generally caused by the air transmission. At present, a common solution is to simply design the diversion tube as a "U"-shaped tube. When the vibration exceeds the standard during the trial production process, it is necessary to The shock absorber is added to the position where the vibration of the pipeline is relatively large, which causes the problem of complex design and structure of the pipeline and high manufacturing cost
