In order to prevent the condensed water from entering the motor, it is usually necessary to install a motor cover on the motor to protect the motor, so as to avoid the intrusion of condensed water into the motor and cause damage to the motor. Or the occurrence of accidents such as electric shock.

For this reason, in the known technology, some technical documents have prepared a motor cover for covering the motor, and installed the motor cover on the motor by a snap connection method to prevent the motor from contacting the heat exchanger. However, in the structure connected by the snap connection, there will inevitably be a gap, and the condensed water can leak to the motor through the gap, thereby reducing the protective effect of the motor cover on the motor.

In other technical documents, in order to improve the sealing performance of the motor cover, a motor cover integrally formed with the base of the air conditioner is prepared, and the motor cover can partially cover the fan blades while covering the motor. The width is greater than the width of the motor to further prevent the condensation water dripping on the edge of the motor cover from flowing into the motor, thereby more effectively preventing the condensation water from contacting the motor. However, if the motor cover is partially covered with the fan blades, the air flow formed when the fan blades rotates will enter the motor cover. When the motor cover is not provided with a guide mechanism, turbulence is likely to occur. Under the action of the turbulence, the motor cover Vibration is prone to occur and even drives the base integrally formed with it to vibrate, thereby generating louder noise, thereby reducing the comfort of the user when using the air conditioner.

In other examples, the guide groove 451 may also form a through connection with a water groove provided on the lower base 3. Here, the aforementioned "end portion" may be the edge portion or the starting portion of the side. In this case, the guide groove can be connected to the water tank of the base obliquely, so that the condensation water on the motor cover can flow into the water tank more conveniently and efficiently, and the drainage effect of the condensation water on the motor cover can be improved. , Further prevent the occurrence of water accumulation on the motor cover.

Optionally, the baffle 452 may have a wind guide surface. In some examples, the air guiding surface may be set toward the air outlet 12 and is suitable for guiding the airflow entering the air conditioner from the air inlet 11 to the blade 10. In other examples, the number of baffles 452 can be two, and the number of corresponding air guide surfaces can also be two. As a result, the airflow entering the air conditioner from the external space can be guided, so that the airflow can be guided to the blades of the air conditioner, so as to further prevent the occurrence of turbulence in the air conditioner and improve the use of the air conditioner. Comfort.

Optionally, the size in the length direction of the rack 431 can be different. In some examples, as shown in FIG. 8, from the rear end 4312 of the rack 431 to the front end 4311 of the rack 431, the radial size of the rack 431 may first become larger and then smaller, that is, the size of the rack 431 It can be a structure with a thick middle and thin ends. Here, as shown in FIG. 2b, the direction connecting the front and rear ends of the rack is defined as the axial direction, and the above-mentioned "radial" is the direction perpendicular to the axial direction, that is, the tooth as shown in FIG. 2b. The direction of the connection between the left and right ends of the bar. In this case, the rack can be set to a structure with a thick middle and thin ends, so that the groove between adjacent racks can be a structure with a large end and a small middle, so that the air flow through the groove changes first When it is smaller, it becomes larger to buffer the air flow, prevent the motor cover from vibrating due to the sudden change of the flow path, and further reduce the possibility of noise.

As another implementation form of the present disclosure, the rear end 4312 of the rack 431 may be close to the rear end of the inner side wall 4211, and the front end 4311 of the rack 431 may be close to the front end of the inner side wall 4211. In this case, the tooth-shaped component can be extended along the rear side of the cover to the front side of the cover to cover the inner side wall of the cover, so that the air flow entering the accommodation space of the motor cover can be fully controlled. Diversion to improve the effect of diversion, thereby enhancing the overall performance of the air conditioner.

As another implementation form of the present disclosure, the rack 431 may have a first type of rack and a second type of rack, wherein the lower end of the first type of rack extends from the other end of the cover plate 421 to the side plate 422 Inclined, the lower end of the second type rack is kept flush. In other examples, the first type of racks may be arranged at intervals and may have at least one interval space, and the second type of racks may be arranged in the interval space. In this case, by setting the racks in the spacing space to the same height state, when the first type of rack and the second type of rack are combined, the height of the groove between adjacent racks and its The internal space remains basically the same, thereby improving the stability of the motor cover's diversion, further reducing the noise generated by the motor cover, and improving the overall performance of the air conditioner.

The above are only optional implementations of the present disclosure and are not intended to limit the present disclosure. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the disclosure Within the scope of protection.
