[0023] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0024] In the description of the present invention, it should be understood that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0025] In the description of the present invention, it needs to be understood that the directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc., are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the motor bracket.

[0026] like Figure 1 and Figure 2 As shown, an embodiment of the present invention discloses an air conditioner indoor unit. For a clearer description, only related components such as a motor and a motor bracket are shown here, and other components of the air conditioner indoor unit are omitted. Figure 1 1 is a schematic diagram of one side of an air conditioner indoor unit according to an embodiment of the present invention, and the other side is the same.

[0027] The air conditioner indoor unit includes: a motor 7 with a motor shaft 71; a motor bracket 3, in which the motor 7 is supported, and the motor shaft 71 passes through the motor bracket 3; an elastic pad 2, which is sleeved on the motor shaft 71, and the elastic pad 2 abuts against the outer side of the motor bracket 3 in the axial direction of the motor shaft 71, so as to absorb the vibration of the motor 7 in the axial direction of the motor shaft 71 and reduce the noise generated by the vibration; a circumferential retaining member 8, both ends of which are connected to the motor bracket 3 and keep contact with the elastic pad 2 in the circumferential direction of the motor shaft 71, so as to absorb the vibration of the motor 7 in the radial direction of the motor shaft 71, reduce the noise generated by the vibration, enhance the dissipation effect of the vibration energy generated by the motor 7, and make the motor 7 more stable in the radial direction of the motor shaft 71. In addition, the circumferential length of the circumferential retaining member 8 is adjustable and can be adjusted according to actual needs; the baffle is installed on the motor bracket 3 and the elastic pad 2 is pressed against the motor bracket 3 in the axial direction of the motor shaft 71. The baffle withstands the vibration passing through the elastic pad 2 and makes the motor 7 more stable in the axial direction. The motor shaft 71 passes through the baffle.

[0028] In some embodiments, Figure 1 and 2 As shown, the two ends of the circumferential retainer 8 are respectively provided with a plurality of positioning parts along the circumference, and the positioning parts can be set as notches 9b, and the plurality of notches can be connected with the corresponding positioning parts on the motor bracket 3, and the corresponding positioning parts can be set as protrusions 9a, so that by selecting different notches 9b that match the protrusions 9a, the circumference of the circumferential retainer 8 between the two protrusions 9a can be changed, thereby changing the degree of tightness of the contact between the circumferential retainer 8 and the elastic pad 2 in the circumferential direction, so as to adapt to different noise reduction requirements. Vice versa, a plurality of protrusions can be set on the two ends of the circumferential retainer 8, and notches can be set on the motor bracket 3. Optionally, the circumferential retainer 8 can be a slender member.

[0029] In some embodiments, Figure 1 and 2 As shown, the circumferential retainer 8 includes a first circumferential retainer 4 and a second circumferential retainer 5, the upper ends of the first circumferential retainer 4 and the second circumferential retainer 5 are connected to the motor bracket 3, and the lower ends of the first circumferential retainer 4 and the second circumferential retainer 5 are connected by a bolt assembly composed of bolts and nuts, so that the distance between the two lower ends increases by loosening the bolts and decreases by tightening the bolts. It is not limited to adjusting by bolts and nuts, as long as the two lower ends can be connected and the distance between them can be adjusted.

[0030] In some embodiments, the elastic pad 2 is made of a buffer material, and the buffer material is mainly used to absorb the transmitted vibration to achieve the purpose of reducing noise.

[0031] In some embodiments, the elastic pad 2 is a circular rubber pad.

[0032] In some embodiments, at least one elastic pad 2 is provided on both axial sides of the motor bracket 3, and one or more elastic pads may be provided, so as to facilitate the realization of a relatively thick buffer layer to meet various noise reduction requirements and facilitate maintenance. The baffle includes a first baffle 1 and a second baffle 6 located on both sides of the motor bracket 3, respectively, and the first baffle 1 and the second baffle 6 respectively press the elastic pads 2 on both sides against the motor bracket 3.

[0033] In some embodiments, the elastic pads 2 located on both sides of the axial direction have different hardnesses. This is because the vibrations on both sides are different, so elastic pads 2 with different hardnesses are selected for each side.

[0034] In some embodiments, the tightness between the first baffle 1 and the second baffle 6 and the elastic pad 2 can be adjusted, for example, by tightening and rotating the connecting bolts between the first baffle 1 and the second baffle 6 and the motor bracket 3, the distance between the first baffle 1 and the second baffle 6 and the motor bracket 3 is changed, thereby changing the distance between the first baffle 1 and the second baffle 6 and the elastic pad 2, and enhancing the dissipation effect of the vibration energy generated by the motor 7. The tightness in the text can be understood as the contact pressure.

[0035] The present invention also provides an air-conditioning device, which includes the above-mentioned air-conditioning indoor unit.

[0036] According to the above description, the air conditioner indoor unit provided by the present invention enhances the dissipation effect of the vibration energy generated by the motor 7 by elastically connecting the motor 7 to the motor bracket 3, thereby achieving the purpose of reducing the noise of the motor components and improving the user experience.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents, which should all be included in the scope of the technical solution for protection of the present invention.
