When a water beating motor of the existing air conditioner drives a water beating impeller to rotate, firstly, water in a water collecting tank on a chassis is beaten by the water beating impeller to form water drops splashed everywhere, secondly, when accumulated water is in an unstable state, surging water waves are easily formed, and the water waves are patted on the wall of the water collecting tank to easily form the splashed water drops. No matter what the water wave is caused by surging or the water drops formed by beating the water impeller are easy to splash on the water beating motor, so that the water beating motor is damaged due to the invasion of the water drops.

In view of this, the present invention proposes a chassis assembly, referring to fig. 1 and 2, which, in an embodiment of the present invention, comprises:

a chassis 10 provided with a water collection tank 100;

the water fetching motor 200 comprises a motor 210 connected to the chassis 10 and a rotating shaft 220 connected to the motor 210 in a driving manner, the motor 210 is positioned at the outer side of the water collecting tank 100, and the wall of the water collecting tank 100 is provided with an avoiding opening 101 for the rotating shaft 220 to movably penetrate through; and

the water blocking member 300 is connected to the rotating shaft 220 and disposed corresponding to the avoiding opening 101.

In the technical scheme of the utility model, the water blocking piece 300 arranged corresponding to the avoidance port 101 can block water drops splashed from the water collecting tank 100, so that the probability that the water drops are splashed onto the motor 210 through the avoidance port 101 is reduced, and the risk that the motor 210 is damaged due to the invasion of flying water is reduced. Specifically, the rotating shaft 220 of the water-fetching motor 200 passes through the avoiding opening 101 and extends into the water collecting tank 100, so as to drive the water-fetching impeller 400 located in the water collecting tank 100 to fetch water. When the water beating impeller 400 beats the accumulated water in the water collecting tank 100, not only water drops splashed around can be formed, but also the accumulated water can form surging water waves. When the water wave hits the edge of the avoidance port 101, the accumulated water may flow through the avoidance port 101 and float toward the motor 210. No matter the splashed water drops or the water overflowing the avoidance port 101 may cause unnecessary damage to the water motor 200, the water is effectively blocked at the side of the water blocking member 300 far away from the motor 210 by the water blocking member 300, and thus the motor 210 is protected. The avoidance port 101 may be provided as the avoidance notch 105 or as an avoidance hole.

Referring to fig. 5 to 7, in the embodiment, optionally, a distance D between the water blocking member 300 and the avoiding opening 101 is in a range of D being greater than or equal to 1.5 mm. It can be understood that if the distance between the water blocking member 300 and the avoiding opening 101 is too small, the water blocking member 300 may easily move and interfere with the edge of the avoiding opening 101 in the process of rotating along with the rotating shaft 220, so that the edge of the water blocking member 300 or the avoiding opening 101 may be damaged, and even the water beating motor 200 and the water beating impeller 400 may have abnormal functions.

Referring to fig. 6, in the present embodiment, optionally, the water blocking member 300 is located on a side of the avoidance port 101 away from the motor 210. Set up water blocking member 300 in the one side of dodging keeping away from motor 210 of mouth 101, can prevent that the water droplet from splashing the outside of water catch bowl 100 to avoid the water droplet to form ponding and flow to motor 210 in the outside of water catch bowl 100, lead to ponding invasion motor 210's problem. However, the design is not limited thereto, and in other embodiments, the water blocking member may be located on a side of the avoiding opening close to the motor.

Referring to fig. 3, 4 and 6, in order to further improve the protection effect of the chassis 10 on the water pumping motor 200, in this embodiment, further, an avoidance groove 110 for the rotating shaft 220 to movably penetrate is further disposed on a groove wall of the water collection groove 100, the avoidance groove 110 extends along an axial direction of the rotating shaft 220, the avoidance groove 110 has a first groove wall 111 close to the motor 210, the avoidance port 101 is located on the first groove wall 111, and the water blocking member 300 is located in the avoidance groove 110. Without loss of generality, the movement locus of the water droplets formed by the water wave agitation or the impact of the water beating impeller 400 on the avoidance opening 101 is difficult to predict, namely, the water droplets flying to the avoidance opening 101 are in a complicated and variable state. However, with the avoidance groove 110 extending in the axial direction of the rotating shaft 220, part of the water droplets can be limited to pass through, that is, the water droplets moving in parallel with the axis of the rotating shaft 220 can pass through the avoidance groove 110 and splash toward the avoidance port 101. The water droplets that can pass through the evacuation slot 110 are blocked by the water blocking member 300 and cannot be splashed into the evacuation port 101. By avoiding the matching of the groove 110 and the water blocking piece 300, the protection effect of the chassis 10 on the water pumping motor 200 is further improved. It should be noted that parallel refers to parallel and near parallel arrangements.

Therefore, the equivalent diameter of the avoiding groove 110 is gradually increased, so that the rotating shaft 220 and the parts thereon can be effectively prevented from moving and interfering with the groove wall of the avoiding groove 110 in the rotating process, and the operation stability and reliability of the water beating motor 200 are improved.

In this embodiment, optionally, in the axial direction along the rotating shaft 220 of the water beating motor 200, the range of the draft angle δ of the second groove wall 112 is recommended to be δ ≧ 3 °. The value of the drawing angle delta is 3 degrees or more, so that the risk of motion interference between the water retaining piece 300 and other parts on the rotating shaft 220 and the second groove wall 112 when the rotating shaft 220 rotates eccentrically can be effectively reduced, and meanwhile, the manufacturing and forming of the groove 110 can be avoided.

However, the design is not limited to this, and in other embodiments, the avoiding opening may be set as an avoiding hole, and the water blocking member may penetrate the avoiding hole.

Referring to fig. 3 and 6, optionally, the edge of the first flange 103 close to the motor 210 extends upward to form a second flange 104, and the notch 105 of the bypass opening 101 is at least partially located on the second flange 104. Through the second turn-ups 104 that sets up, can play the effect that the structure is strengthened to the first turn-ups 103 of water catch bowl 100 to reduce and dodge the risk that the breach 105 of mouthful 101 takes place plastic deformation, and then guarantee the pivot 220 and dodge the safe interval between the edge of mouthful 101, avoid the pivot 220 in rotatory in-process with dodge mouthful 101 and take place the motion interference.
