Problems solved by technology
[0005] (1) The existing air conditioner produces abnormal noise due to the vibration of the motor as a whole, resulting in poor performance of the air conditioner
[0006] (2) The existing controllability of the overall vibration state and noise parameters of the motor is low
It is difficult to guarantee the consistency of after-sales product quality

Embodiment 2
[0050] The other structures of this embodiment are the same as those of this embodiment, the difference being that the shape of the tuyere 5 of the mounting plate of the fan is trapezoidal, the vertical piece 42 and the two horizontal pieces 41 are connected non-perpendicularly, and the shape of the reinforcing piece 4 needs to be consistent with Only when the shapes of the tuyere 5 are matched can a better enhanced vibration damping effect be achieved.
[0051] Therefore, the shape of the reinforcing sheet 4 is not limited to the two cases of embodiment 1 and embodiment 2, which can be customized according to actual needs.
Embodiment 3
[0053] This embodiment also provides an air conditioner, the air conditioner is equipped with the noise control device of the air conditioner terminal unit described in Embodiment 1 or Embodiment 2.

The invention belongs to the technical field of air conditioner noise reduction equipment, and discloses a noise control device and method for an air conditioner tail end machine and an air conditioner. A mounting plate of an tail end vibration source of the air conditioner tail end machine is provided with a reinforced vibration damping device, specifically, a reinforcing sheet is welded to an air hole of a mounting plate of a fan; and the reinforcing sheet is of a C-shaped structure, is matched with the air hole of the mounting plate of the fan, can strengthen the anti-vibration capability of the structure, increases the vibration damping, and can effectively avoid the structural abnormal sound caused by shaking of a motor of the tail end machine. Compared with the prior art, the deviceand method and the air conditioner has the advantages of strong universality, high guarantee of reliability of multi-system and multi-air channel function operation; the mounting plate is strong in shock resistance, the exacerbation of resonance and noise in the operation process of the fan is avoided; and the function adaptability is strong.
Description
technical field [0001] The invention belongs to the technical field of air conditioner noise reduction equipment, and in particular relates to a noise control device and method for an air conditioner terminal unit and an air conditioner. Background technique [0002] At present, the closest existing technology in the industry: with the gradual development of the market economy, air conditioners have become one of the indispensable household appliances for millions of households. Consumers have a higher understanding of living experience and customized enjoyment. Preferably, home-installed central air conditioners have gradually become the first choice of consumers. The centralized energy supply and deployment represented by the application of the multi-functional frequency conversion VRF functional system is favored by customers. For the VRF functional system, when the whole machine is in functional operation, based on the control of the flow path and system of the whole m...
