The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0048] Current air conditioner indoor units, such as wall-mounted air conditioners and ducted air conditioners, have cross-flow fans installed in the indoor unit section. The noise and vibration generated during the operation of the cross-flow fan can easily be transmitted to the base and middle frame of the indoor unit, resulting in abnormal noise problems.

[0049] For this, please refer to Figures 1 to 7 This application provides an indoor air conditioning unit 100, including a cross-flow fan 10 and a base 50. The cross-flow fan 10 includes a cross-flow impeller 11 and a motor 12. The base 50 is provided with a fan mounting structure 51, which includes a plurality of spaced support protrusions 511 for supporting the motor 12 of the cross-flow fan 10.

[0050] It should be noted that the cross-flow fan 10 can be an external rotor fan, an internal rotor fan, etc., and is not limited here. The installation method of the cross-flow impeller 11 and the motor 12 is not limited; the cross-flow impeller 11 and the motor 12 can be integrated, or they can be separate, etc., and is not limited here. The number of the supporting protrusions 511 is not limited; it can be two, three, four, ten, etc., and is not limited here. The fan mounting structure 51 can include only the supporting protrusions 511, or it can include other mounting structures, and is not limited here.

[0051] It should be emphasized that currently, the cross-flow fan 10 is generally installed directly on the motor mount on the base 50. The motor 12 and the motor mount are in surface-to-surface contact, resulting in a large contact area. The noise and vibration generated by the motor 12 during operation will be directly transmitted to the base 50 and the middle frame of the indoor unit, which can easily cause abnormal noises in the indoor unit of the air conditioner during operation.

[0052] In an embodiment of this application, the mounting structure includes a plurality of spaced-apart support protrusions 511. The plurality of support protrusions 511 are used to support the motor 12 of the cross-flow fan 10. When the motor 12 of the cross-flow fan 10 is supported by the support protrusions 511, since the plurality of support protrusions 511 are spaced-apart, the gap between the plurality of support protrusions 511 will not contact the motor 12 of the cross-flow fan 10. This reduces the contact area between the motor 12 and the fan mounting structure 51 during installation, thereby weakening the transmission of noise and vibration and solving the problem of abnormal noise in the existing air conditioning indoor unit 100.

[0053] The specific shape of the supporting protrusion 511 is not limited. It can be a regular shape, such as a rectangle, a cylinder, etc., or an irregular shape, etc., and is not limited here.

[0054] Please refer to this carefully. Figure 2 and 3 In some embodiments, the support protrusion 511 includes a gradient section 5111, the cross-sectional area of ​​which gradually decreases from the base 50 toward the motor 12.

[0055] In this embodiment, by setting the gradient section 5111, compared to the embodiment with an unchanged cross-section, it allows for a larger gap between the multiple support protrusions 511 at the ends that contact the motor 12, resulting in a smaller contact area between the support protrusions 511 and the motor 12, thus improving the noise and vibration isolation effect. Furthermore, the larger cross-sectional area near the base 50 effectively enhances the stability of the support.

[0056] The arrangement of the multiple support protrusions 511 is not limited. They can be arranged in an array, scattered, in a single row, or in multiple rows, etc., and are not limited here.

[0057] In some embodiments, multiple support protrusions 511 are arranged in multiple rows along the axial direction of the cross-flow impeller 11. This arrangement of multiple support protrusions 511 in multiple rows can effectively improve the stability of the support for the motor 12.

[0058] Specifically, they are arranged in multiple rows, which can be two, three, or four rows, and are not limited here. In some embodiments, the multiple support protrusions 511 are arranged in two rows.

[0059] During the operation of the cross-flow fan 10, since the cross-flow impeller 11 rotates, it is necessary to maintain a certain gap between the cross-flow impeller 11 and the base 50 to avoid the rotation of the cross-flow impeller 11 causing damage to the base 50, or the base 50 interfering with the rotation of the cross-flow impeller 11.

[0060] Please refer to this carefully. Figure 2 and 3 In some embodiments, the fan mounting structure 51 further includes a boss 512 disposed on the base 50, the boss 512 being used for positioning the motor 12, and the support protrusion 511 being disposed on the boss 512.

[0061] In this embodiment, by setting the boss 512, when the motor 12 of the cross-flow fan 10 is installed on the boss 512, the cross-flow fan wheel 11 of the cross-flow fan 10 can be suspended in the air, thereby maintaining a certain gap with the base 50, so that the cross-flow fan wheel 11 can rotate smoothly.

[0062] It should be noted that the boss 512 and the base 50 can be integrally formed or separate, and no limitation is made here. In some embodiments, the boss 512 and the base 50 are integrally formed.

[0063] To prevent the motor 12 from moving, in some embodiments, the air conditioner indoor unit 100 further includes a positioning structure 60, which includes a positioning part and a mating part. One of the positioning part and the mating part is disposed on the motor 12, and the other is disposed on the boss 512. The positioning part is used for positioning and mating with the mating part.

[0064] In the scheme of this embodiment, by setting the positioning structure 60, when the motor 12 is placed on the boss 512, the positioning part and the mating part can be used to position the motor 12 on the boss 512, thereby preventing the motor 12 from moving.

[0065] Specifically, the specific implementation of the positioning part and the mating part is not limited. It can be in the form of positioning groove 62 and positioning protrusion 61, or in the form of two magnetic suction parts, or in the form of two buckles, etc., and is not limited here.

[0066] Please refer to the following: Figures 8 to 12 In some embodiments, one of the positioning part and the mating part includes a positioning protrusion 61 and the other includes a positioning groove 62, and the positioning protrusion 61 and the positioning groove 62 are in clearance fit.

[0067] Specifically, the positioning part and the mating part, one of which includes a positioning protrusion 61 and the other includes a positioning groove 62. The positioning protrusion 61 may be disposed on the motor 12 and the positioning groove 62 may be disposed on the boss 512, or the positioning protrusion 61 may be disposed on the boss 512 and the positioning groove 62 may be disposed on the motor 12, etc., and so on. No limitation is made here.

[0068] The positioning protrusion 61 and the positioning groove 62 are fitted with a gap, so that when the positioning protrusion 61 is in the positioning groove 62, it can maintain a certain gap with the groove wall of the positioning groove 62, thereby preventing the vibration and noise of the motor 12 from being transmitted from the positioning protrusion 61 to the boss 512.

[0069] Specifically, the size of the clearance fit is not limited and can be selected according to actual needs. In some embodiments, the size of the clearance fit is 0.2 to 0.3 mm. On the one hand, this can avoid the gap being too small, which would result in poor noise and vibration isolation, and on the other hand, it can also avoid the gap being too large, which would cause the motor 12 to shake significantly.

[0070] In some embodiments, the motor 12 includes a main body 121 and a housing 122. The housing 122 is fitted onto the outside of the main body 121, and the positioning protrusion 61 is formed on the housing 122. The positioning protrusion 61 has a glue-steeping groove 611 on the side facing the main body 121.

[0071] In the corresponding embodiment, by providing a glue-steeping groove 611 on the side of the positioning protrusion 61 facing the main body 121, the glue-steeping groove 611 can be used to reduce the thickness of the casing 122 during manufacturing, preventing deformation of the casing 122. Furthermore, the positioning protrusion 61 itself has high strength, so even if the glue-steeping groove 611 is provided, it will not significantly affect the overall strength of the casing 122.

[0072] Please refer to the following: Figures 13 to 18 In order to prevent the cross-flow fan wheel 11 from moving in its axial direction after being installed on the base 50, in some embodiments, the fan mounting structure 51 further includes a limiting block 53 provided on the boss 512. The limiting block 53 is located on the side of the support protrusion 511 away from the cross-flow fan wheel 11, so as to limit the motor 12 in its axial direction.

[0073] In the scheme of this embodiment, by setting the limiting block 53, which is located on the side of the support protrusion 511 away from the cross-flow fan wheel 11, the motor 12 can be limited in its axial direction, thereby effectively preventing the cross-flow fan wheel 11 from moving in its axial direction after it is installed on the base 50.

[0074] It should be noted that when the motor 12 is installed on the base 50, the motor 12 may abut against the limiting block 53 or there may be a certain gap. This is not limited here. In some embodiments, there is a certain gap between the motor 12 and the limiting block 53. This setting can prevent the motor 12 from transmitting vibration and noise to the limiting block 53.

[0075] Specifically, in some embodiments, the fan mounting structure 51 further includes a pressure cover 54, which is mounted on the boss 512 and located on the outside of the motor 12, for pressing the motor 12. Correspondingly, the limiting block 53 can also be set on the pressure cover 54 to limit the motor 12 in its axial direction.

[0076] The specific implementation of the motor 12 is not limited and can be selected according to actual needs. In some embodiments, the periphery of the main body 121 is provided with a shock-absorbing pad 123, and the side of the housing 122 facing the main body 121 has a mounting groove corresponding to the shock-absorbing pad 123.

[0077] In the scheme of this embodiment, by setting the shock-absorbing pad 123, the noise and vibration transmitted from the main body 121 to the housing 122 can be effectively blocked, thereby reducing the noise of the motor 12. Furthermore, the housing 122 has a mounting groove formed on the side facing the main body 121 corresponding to the shock-absorbing pad 123. During actual installation, the shock-absorbing pad 123 is installed in the mounting groove, thereby achieving the connection and positioning between the main body 121 and the housing 122 through the cooperation of the shock-absorbing pad 123 and the mounting groove.

[0078] Specifically, the specific implementation form of the shock-absorbing pad 123 is not limited. It can be in the form of a rubber pad or a silicone pad, etc., and is not limited here. The number of the shock-absorbing pad 123 is not limited. It can be one, two, three, etc., and is not limited here.

[0079] In some embodiments, the main body 121 has a motor hole 1211, one end of the cross-flow fan 11 is provided with a rotating shaft, the rotating shaft is inserted into the motor hole 1211, and the end of the cross-flow fan 11 facing the main body 121 is also provided with a magnetic connector.

[0080] In the scheme of this embodiment, during the actual assembly of the cross-flow fan 10, it is only necessary to insert the shaft of one end of the cross-flow fan wheel 11 into the motor hole 1211. At this time, the magnetic connector will magnetically attract the motor 12, thereby completing the installation of the cross-flow fan wheel 11 and the motor 12. The whole installation process is very simple.

[0081] Please refer to this carefully. Figures 1 to 7 To improve the stability of the installation of the cross-flow fan 11, in some embodiments, the fan mounting structure 51 further includes a boss 512 and a pressure cover 54 disposed on the base 50. The boss 512 is used for positioning the motor 12, and the support protrusion 511 is disposed on the boss 512. The pressure cover 54 is installed on the boss 512 and is located outside the motor 12, and is used to press the motor 12.

[0082] In the corresponding embodiment, during the installation process, the motor 12 is first placed on the boss 512, and then the cover 54 is closed. At this time, the cover 54 can press down on the motor 12 to prevent it from moving, thereby effectively improving the stability of the installation of the cross-flow fan wheel 11.

[0083] Specifically, the installation method between the pressure cap 54 and the boss 512 is not limited. The pressure cap 54 can be rotatably installed on the boss 512 at one end, or it can be detachably installed on the boss 512, etc., and no limitation is made here.

[0084] It should be noted that the pressure cover 54 will press down on the motor 12. Therefore, there will be contact between the pressure cover 54 and the motor 12, and the noise and vibration of the motor 12 will be transmitted to the pressure cover 54.

[0085] In order to reduce noise and vibration transmission between the pressure cover 54 and the motor 12, in some embodiments, the pressure cover 54 is provided with a pressing block 541 protruding on the side facing the motor 12, and when the motor 12 is installed on the boss 512, the pressing block 541 abuts against the outer peripheral side of the motor 12.

[0086] In the scheme of this embodiment, by setting the pressing block 541, the contact area between the pressing cover 54 and the motor 12 can be reduced. On the one hand, the pressing force can be more concentrated and the pressing effect can be better. On the other hand, the noise and vibration transmission between the pressing cover 54 and the motor 12 can be reduced.

[0087] This utility model also proposes an air conditioner, which includes an indoor unit 100. The specific structure of the indoor unit 100 is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
