[0053] As Figures 1-19 The air conditioner 100 according to one embodiment of the utility model includes a machine body 1 and a centrifugal fan wheel assembly 3.

[0054] The machine body 1 is provided with a machine body air inlet 112 and a machine body air outlet 122, the machine body air outlet 122 is arranged on the bottom wall 121 of the machine body 1, and the machine body air inlet 112 and the machine body air outlet 122 are provided with a heat exchanger assembly 2, the centrifugal fan wheel assembly 3 includes a driving structure 4 and a centrifugal fan wheel 5, the centrifugal fan wheel 5 is rotatably installed in the machine body 1, the driving structure 4 is connected with the centrifugal fan wheel 5, and the driving structure 4 is used to drive the centrifugal fan wheel 5 to rotate to drive the airflow to flow from the machine body air inlet 112 to the machine body air outlet 122.

[0055] Among them, the air conditioner 100 is an air conditioner, which is provided with air conditioner host and other structures, and the air conditioner 100 is a kind of for providing processing air temperature change unit for space area (generally closed).

An installation space can be formed inside the body 1, allowing the operating components of the air conditioner 100 to be installed within this space and fixedly connected to the body 1, thus ensuring reliable component installation and overall reliable operation of the air conditioner 100. The body 1 includes an air inlet 112 and an air outlet 122. Outside air enters the body 1 through the air inlet 112 and undergoes heat exchange within the body 1 to cool or heat the airflow. The cooled or heated airflow is then delivered to the room through the air outlet 122 to cool or heat the room, meeting different user needs.

[0057] Furthermore, the unit 1 is provided with a bottom wall 121. When the unit 1 is installed on a wall, the bottom wall 121 is located at the bottom of the unit 1, and the air outlet 122 is located on the bottom wall 121 of the unit 1, that is, the air outlet 122 is located below the unit 1.

[0058] A heat exchanger assembly 2 is installed between the air inlet 112 and the air outlet 122 of the unit. External airflow enters the unit 1 through the air inlet 112 and flows through the heat exchanger assembly 2 to exchange heat, allowing the airflow to be heated or cooled. The heated or cooled airflow can then circulate through the air outlet 122 to the room, thus heating or cooling the indoor environment. When cooling is required, the airflow exchanges heat with the heat exchanger assembly 2, transforming it into a low-temperature airflow, which is then delivered to the room through the air outlet 122 to cool the room. When heating is required, the airflow exchanges heat with the heat exchanger assembly 2, transforming it into a high-temperature airflow, which is then delivered to the room through the air outlet 122 to heat the room, ensuring user comfort.

[0059] In addition, the centrifugal fan assembly 3 is arranged in the machine body 1, the centrifugal fan assembly 3 is provided with a driving structure 4 and a centrifugal fan 5, the driving structure 4 and the centrifugal fan 5 are power connected, that is, the driving structure 4 can be used to drive the centrifugal fan 5 to rotate, the centrifugal fan 5 is rotatably installed on the machine body 1, when the driving structure 4 operates, the centrifugal fan 5 can be driven to rotate relative to the machine body 1, and when the centrifugal fan 5 rotates, the airflow can be driven to flow from the machine air inlet 112 to the machine air outlet 122, so that the airflow after heat exchange in the machine body 1 can be transported to the indoor through the machine air outlet 122, thereby the indoor temperature can be adjusted, and the centrifugal fan 5 can ensure the airflow, improve the airflow transportation effect, and thus the user experience can be ensured.

[0060] According to the air conditioner 100 of the embodiment of the utility model, the machine air outlet 122 is arranged on the bottom wall 121 of the machine body 1, and the airflow can be driven to flow from the machine air inlet 112 to the machine air outlet 122 when the centrifugal fan 5 rotates, so that the air conditioner 100 can send the hot air flow to the bottom layer of the indoor in the heating state through the machine air outlet 122, thereby the heating speed of the air conditioner 100 can be improved, the heating effect of the air conditioner 100 on each place of the indoor can be ensured, the user experience can be ensured, the use effect is better, and the application range is wider.

[0061] In some embodiments, the air conditioner 100 further comprises a volute assembly 7, the volute assembly 7 is installed in the machine body 1, the volute assembly 7 is formed with a centrifugal air duct 75, the centrifugal fan 5 is installed in the centrifugal air duct 75, and the bottom of the centrifugal air duct 75 is formed with a volute air outlet 74 opposite to the machine air outlet 122.

[0062] Specifically, the air conditioner 100 is further provided with a volute assembly 7, as shown in Figure 3 The volute assembly 7 is installed in the machine body 1 and can be integrally formed with the machine body 1 or connected to the machine body 1 through a connecting piece, and the volute assembly 7 is a shell, the inside of which is formed with a centrifugal air duct 75, the centrifugal fan 5 can be installed in the centrifugal air duct 75 and can rotate relative to the inner wall of the volute assembly 7, when the driving structure 4 drives the centrifugal fan 5 to rotate, the centrifugal fan 5 rotates relative to the inner wall of the volute assembly 7 to drive the airflow in the centrifugal air duct 75 to flow, and the bottom of the centrifugal air duct 75 is formed with a volute air outlet 74 opposite to the machine air outlet 122.

[0063] Further, when the centrifugal impeller 5 rotates, external air can flow into the body 1 through the air inlet 112 of the body, and can exchange heat with the heat exchanger assembly 2 in the body 1. The airflow after heat exchange can flow into the centrifugal air duct 75, and then can be accelerated and pressurized by the centrifugal impeller 5.

[0099] When the drive motor 41 is operating, the mounting cover 44 has a relative displacement tendency with respect to the mounting body 43, which causes the positioning mating part of the second positioning part 432 and the positioning mating part 442 to be subjected to force. By providing multiple second positioning parts 432 and second positioning mating parts 442, the force can be distributed to multiple points, thereby reducing the effect of the force and preventing the second positioning parts 432 and the second positioning mating parts 442 from breaking, ensuring positioning reliability and extending service life.
