In the structural assembly of the existing air conditioner, in order to achieve good heating or refrigerating effect, the setting position of the fan blade is usually close to the heat exchanger, the motor connected with the fan blade is also close to the heat exchanger, condensed water is often generated at the heat exchanger and other parts in the running process of the air conditioner, and in order to prevent the condensed water from entering the motor, a motor cover is usually required to be installed on the motor so as to realize protection of the motor, thereby avoiding accidents such as motor damage, fire house or electric shock caused by the invasion of the condensed water into the motor.

For this reason, in the prior art, some technical documents prepare a motor cover for covering the motor, and mount the motor cover on the motor by means of a snap-fit to prevent the motor from contacting the heat exchanger. However, in the structure connected in the clamping manner, a gap is inevitably formed, and condensed water can leak to the motor through the gap, so that the protection effect of the motor cover on the motor is reduced.

In other technical documents, in order to improve the sealing performance of the motor cover, the motor cover integrally formed with the base of the air conditioner is manufactured, and the motor cover can cover the motor and can partially cover the fan blade, so that the width of the motor cover is larger than the width of the motor, and condensed water dropping on the edge of the motor cover is further prevented from flowing into the motor, thereby more effectively preventing the condensed water from contacting the motor. However, the motor cover partially covers the fan blades, air flow formed when the fan blades rotate can enter the motor cover, turbulence is easy to generate under the condition that a flow guide mechanism is not arranged in the motor cover, and under the action of the turbulence, the motor cover is easy to vibrate and even drive a base integrally formed with the motor cover to vibrate, so that larger noise is generated, and therefore, the comfort of a user when the air conditioner is used is reduced.

Disclosure of Invention

In other examples, the guide groove 451 may be connected to a water tank provided in the lower chassis 3. Here, the "end" may be the edge portion or the start portion of the side. Under the condition, the guide groove can be obliquely connected to the water tank of the base, so that condensed water on the motor cover can flow into the water tank more conveniently and efficiently, the effect of drainage effect of the condensed water on the motor cover is improved, and the occurrence of water accumulation and other conditions on the motor cover is further prevented.

Preferably, the deflector 452 may have an air guiding surface. In some examples, the air guiding surface may be disposed towards the air outlet 12, and adapted to guide the air flow entering the air conditioner from the air inlet 11 onto the fan blade 10. In other examples, the number of the air guide plates 452 may be two, and the number of the corresponding air guide surfaces may be two. Therefore, the air flow entering the air conditioner from the external space can be guided to the fan blade of the air conditioner, so that the occurrence of turbulent flow and the like in the air conditioner is further prevented, and the use comfort of the air conditioner is improved.

Preferably, the size of the rack 431 in the length direction may 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 dimension of the rack 431 may be increased and decreased, that is, the dimension of the rack 431 may be a structure having thick middle and thin both ends. Here, as shown in fig. 2b, the direction of the front and rear end connection lines of the rack is defined as an axial direction, and the above-mentioned "radial direction" is a direction perpendicular to the axial direction, that is, a direction of the left and right end connection lines of the rack as shown in fig. 2 b. Under the condition, the racks can be arranged into a structure with thick middle and thin two ends, and the grooves between adjacent racks can be of a structure with big middle and small middle ends, so that the flow rate of the air flow passing through the grooves is firstly reduced and then is increased, the air flow is buffered, the occurrence of the condition that the motor cover is impacted and vibrated due to sudden change of the flow path of the air flow is prevented, and the possibility of noise generation is further reduced.

As another implementation of the present invention, the rear end 4312 of the rack 431 may be near the rear end of the inner sidewall 4211, and the front end 4311 of the rack 431 may be near the front end of the inner sidewall 4211. Under this circumstance, can extend the profile of tooth subassembly to the front side of lid along the rear side of lid to the inside wall of cover is covered, from this, can carry out abundant water conservancy diversion to the air current that gets into the accommodation space of motor lid, improves the effect of water conservancy diversion, thereby promotes the holistic performance of air conditioner.

As another implementation form of the present invention, the rack 431 may have a first type of rack and a second type of rack, wherein a lower end of the first type of rack is inclined from the other side end of the cover plate 421 toward the side plate 422, and the lower end of the second type of rack is maintained flush. In other examples, the first type of racks may be spaced apart and may have at least one spaced apart space, and the second type of racks may be disposed within the spaced apart space. Under the condition, the racks in the interval space are set to be in the equal-height state, and when the first type racks and the second type racks are combined, the heights of the grooves between the adjacent racks and the inner space of the grooves are kept basically the same, so that the flow guiding stability of the motor cover is improved, the noise generated by the motor cover is further reduced, and the overall performance of the air conditioner is improved.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
