[0051] In some embodiments of this utility model, such as Figure 4 As shown, the motor assembly 20 is provided with screw holes 210 for screws to be screwed in. The frame 10 has a partition 120 for defining a motor receiving space 110. The partition 120 is located between the screw holes 210 and the mounting holes 310. The partition 120 is provided with through holes 130. Screws pass through the mounting holes 310 and the through holes 130 and are threaded into the screw holes 210 to fix the motor cover 30, the frame 10 and the motor assembly 20 together.

[0052] In this embodiment, the motor assembly 20 is provided with screw holes 210, the partition 120 of the frame 10 is provided with through holes 130, and the motor cover 30 is provided with mounting holes 310. The partition 120 is located between the screw holes 210 and the mounting holes 310.

[0054] In this embodiment, a water guide groove 320 is provided above the motor cover 30. When the indoor unit 100 is running, condensate is generated on its internal evaporator, and the condensate drips down onto the motor cover 30. Because the water guide groove 320 is provided on the upper surface of the motor cover 30, the condensate dripping onto the motor cover 30 is guided out by the water guide groove 320, preventing the condensate from flowing into the motor assembly 20 from the motor cover 30, preventing damage to the motor assembly 20, improving the operational stability of the motor assembly 20, and thus improving the operational stability of the indoor unit 100 of the air conditioner.

[0055] In some embodiments of this utility model, such as Figure 2 As shown, a side baffle plate 330 is provided on the upper surface of the motor cover 30 to define the water guide groove 320.

[0056] In this embodiment, a side baffle plate 330 is provided on the upper surface of the motor cover 30, and the side baffle plate 330 and the motor cover 30 define a water guide groove 320. A front baffle plate 340 is also provided at the front end of the upper surface of the motor cover 30, and a drain hole 350 is provided at the inner end of the front baffle plate 340. After the condensate drips down onto the motor cover 30, it is guided forward by the water guide groove 320. When it flows to the front end of the motor cover 30, the front baffle plate 340 guides the condensate to flow forward a short distance before flowing downward. Some of the condensate is discharged from the drain hole 350 at the inner end of the motor cover 30. By setting the front baffle plate 340, the condensate on the upper surface of the motor cover 30 is prevented from flowing downward into the motor assembly 20, preventing damage to the motor assembly 20, improving the operational stability of the motor assembly 20, and thus improving the operational stability of the indoor unit 100 of the air conditioner.

[0057] In some embodiments of this utility model, such as Figure 1 As shown, the frame 10 also has a front water inlet 140 located on the front side of the motor housing space 110. The front end of the motor cover 30 extends into the front water inlet 140.

[0058] In this embodiment, the frame 10 also includes a front water inlet 140, which is located on the front side of the motor housing space 110, i.e., on the front side of the motor assembly 20. The front end of the motor cover 30 extends into the front water inlet 140. After condensate drips down onto the motor cover 30, it is guided forward by the water guide channel 320. When it flows to the front end of the motor cover 30, the front baffle 340 guides the condensate to flow forward a short distance before flowing down into the front water inlet 140. The water inlet collects the condensate and discharges it from the indoor unit 100. By setting up the front water inlet 140, the condensate flowing down along the motor cover 30 enters the front water inlet 140, preventing bacteria from growing in the indoor unit 100 and thus preventing bacteria carried by the air from entering the room and affecting the user's health.

[0059] In some embodiments of this utility model, such as Figure 1 As shown, the frame 10 also has a front water inlet 140 located on the front side of the motor housing space 110. The drain hole 350 is located on the upper side of the front water inlet 140.

[0060] In this embodiment, the drain hole 350 is located above the front water receiving tank 140. After condensate drips down onto the motor cover 30, it is guided forward by the water guide 320. As it flows to the front end of the motor cover 30, some of the condensate flows from the drain hole 350 at the inner end of the motor cover 30 into the water receiving tank. The water receiving tank collects the condensate and discharges it from the indoor unit 100. The front water receiving tank 140 prevents bacteria from growing inside the indoor unit 100, thus preventing bacteria carried by the air from entering the room and affecting the user's health.

[0061] In some embodiments of this utility model, such as Figure 1 As shown, the frame 10 also has a rear water inlet 150 located behind the motor housing space 110. The rear end of the motor cover 30 extends into the rear water inlet 150.

The rear end of the motor cover 30 extends into the rear water inlet 150. After condensate drips down onto the motor cover 30, some of it is guided to the rear by the water guide channel 320, flowing from the rear end of the motor cover 30 into the rear water inlet 150. The water inlet collects the condensate and discharges it from the indoor unit 100. The rear water inlet 150 prevents bacteria from growing inside the indoor unit 100, thus avoiding the entry of airborne bacteria into the room and potentially affecting the user's health.

[0063] In some embodiments of this utility model, such as Figure 3 and Figure 6 As shown, a first locking protrusion 360 is provided at the rear end of the motor cover 30, and a second locking protrusion 160 is provided inside the rear water tank 150.
