Problems solved by technology

[0004] 1. Aerodynamic noise of cross-flow fans; mainly including rotating noise and eddy current noise
[0005] 2. Structural vibration noise, mainly due to structural vibration noise generated by motor vibration and fan rotation
[0006] 3. The pulsation noise of the air flow caused by the high-speed flow of the refrigerant in the pipeline, and the turbulent noise generated by the refrigerant at the elbow of the pipeline, the diversion and confluence of the inlet and outlet
The disadvantage of this installation method is that when the fan and motor are installed in place, there must be a certain space between the motor and the other end of the cavity, the motor will move laterally during operation, and when the fan is running, vibration will inevitably occur , so that the mechanical vibration between the fan and the motor produces noise
However, the base of the air conditioner is on the outdoor unit instead of the structure of the indoor unit of the air conditioner, and the motor and the compressor chamber are arranged together, so this structure cannot be directly applied to the structural design of the indoor unit, and technical expertise is required The personnel can obtain the

Embodiment 1

[0036] As a simple way, the simplest implementation in this embodiment, see image 3 , but with image 3 The slight difference is that the motor cover is not used in this embodiment.

[0037] One end side of the base 5 is provided with a motor chamber 1 for accommodating the motor 2 standing upright on one side. Because there is no fixing effect of the motor cover plate, a matching fixing device matched with the motor chamber fixing device is set on the shell of the motor. For example, as shown in the figure, two screw holes are provided on the periphery of the motor chamber 1, then two screw holes are also provided at the corresponding positions of the motor casing, and the motor is fixed in the motor chamber by screws. Although this method has a simpler structure, it has special requirements on the motor casing, which brings some inconvenience, so it is not the best method.

Embodiment 2

[0039] In this way, use the motor cover, such as Figure 2 to Figure 4 As shown, the fixing device 11 on the periphery of the motor cavity is two first screw holes, and the matching fixing device 31 matching the fixing device is two second screw holes, put the motor into the motor cavity, and insert the motor shaft into the fan shaft hole , Then, the motor cover plate 3 covers the opening of the cavity, and the first screw hole and the second screw hole are screwed and fixed into one body by screws. When covering the motor cover plate 3, a positioning device 33 that is convenient for the motor cover plate to align with the motor cavity is provided on the edge of the motor cover plate 3, and the positioning device 33 is a small rectangular sheet integrated with the motor cover plate shaped claw, or a small semicircular convex button integrated with the motor cover or in other ways, at the same time, a matching positioning device matching the size and shape of the positioning de...

Embodiment 3

[0042] The structure is basically the same as that of Embodiment 2 (the structure is omitted in the drawings), except that the fixing device 11 on the periphery of the motor cavity has two buckles or slots, and the matching fixing device 31 matching the fixing device has two slots or buckle, put the motor into the motor chamber, insert the motor shaft into the fan shaft hole, then cover the opening of the cavity with the motor cover 3, and fasten the motor cover through the buckle / slot and the slot / slot It is snapped and fixed into one body with the motor cavity.

Abstract

The invention relates to an air conditioning room indoor machine detachable fan motor mounting structure, which comprises: a indoor machine fan vaporizer system (4), a motor (2) a base (5) for containing the motor and the vaporizer system, a motor chamber (1) at one side of base (5) to contain a side-upright motor (2), and a motor cover plate (3) at the open of motor chamber (1) whose area is not less than the section of motor chamber. The invention changes present positive mounting into side mounting, therefore, when detaching the motor, only needing removing the cover and side drawing out the motor, without moving the vaporizer. The invention can supply the motor tightly to avoid transverse displacement to reduce the vibration noise.

Description

technical field [0001] The invention relates to a fan motor installation structure, in particular to a fan motor installation structure for an air conditioner indoor unit which is easy to disassemble. Background technique [0002] The noise level is an important indicator to measure the performance of the air conditioner. Solving the noise problem of wall-mounted air conditioners has always been the focus and difficulty of technical research by major air conditioner manufacturers at home and abroad. [0003] The noise of the wall-mounted air conditioner is a complex acoustic system composed of various sound sources. The main components of the noise source are as follows: [0004] 1. The aerodynamic noise of the cross-flow fan; mainly including rotating noise and eddy current noise. [0005] 2. Structural vibration noise is mainly due to structural vibration noise generated by motor vibration and fan rotation. [0006] 3. The pulsating noise of the air flow generated by th...
