Abstract
The invention discloses a low-noise blower mounting structure for a vertical air conditioner cabinet. The low-noise blower mounting structure comprises a back plate and blower bottom plates welded with the back plate. Motor mounting feet are fixed with the blower bottom plates through connection mechanisms. Each connection mechanism comprises a machine foot screw and nuts. A shock absorption rubber cushion, a shock absorption rubber ring, a flat gasket and a spring gasket which are sleeved on each machine foot screw are arranged between each motor mounting foot and the corresponding nuts in sequence. The shock absorption rubber cushion and the motor mounting foot are adapted with each other in size and shape, wherein shock absorption balance cotton is further arranged between the motor mounting foot and the shock absorption rubber cushion which are located below the same motor. The low-noise blower mounting structure disclosed by the invention has the advantages of scientific and reasonable in entire structure and design, easiness of manufacture, convenience for mounting and assembling, wear resistance and good durability even under a more adverse condition of a higher use environment temperature, and long service life. As the shock absorption rubber cushion of each motor mounting foot has a good de-noising effect, the low-noise blower mounting structure can ensure the balance operation of an air conditioner blower, therefore, the noise of the entire machine is lower and the tone quality is better.
Description
Technical field
The present invention relates to the hvac equipment technical field, relate in particular to a kind of low noise vertical air conditioner cabinet fan installing structure.
Background technology
At present, the fan installing structure of existing vertical air conditioner cabinet on the market is because structural design is unreasonable; Make that the assembling uniformity and the balance of its product structure design are all poor; The quality of stability reliability is difficult to control, causes the problem of doing over again in batches easily, and the shock-proof effect of its design simultaneously is also poor; Be easy to generate vibration and cause resonance, so noise is all bigger.In addition, the installation foot of blower fan is also shorter service life, under the higher environment for use of temperature, occurs easily galling the mashed situation of mill, and this can make air-conditioning draught fan be easy to generate very big abnormal sound, has a strong impact on the quality of product, often suffers user's complaint.
Summary of the invention
In view of this, the objective of the invention is to, overcome the weak point of prior art design, a kind of low noise vertical air conditioner fan installing structure is provided,, reduce noise through the reasonable setting of structure.
