The blower 23 includes a motor and a fan, the fan may be located in the second scroll casing 22, and a portion of the motor protrudes from an end of the second scroll casing 22, and the protruding portion is referred to as a protrusion 231.

When the indoor heat exchange unit 10 cools the indoor hot air, the indoor hot air enters the first volute 12 and contacts with the first volute 12 affected by the cooling state, and is condensed into water drops on the surface of the first volute 12, and the water drops fall under the action of gravity. Due to the installation arrangement, the fan 23 protrudes from one side of the second volute 22 close to the water baffle 30, and the falling water drops are gathered into condensed water and easily drop on the protruding part 231 of the fan 23.

In the embodiment shown in FIG. 2, the dam 30 includes a first dam 31, and the first dam 31 is connected to the second volute 22.

Therefore, the first water baffle 31 of the water baffle 30 is connected with the second volute 22, and can sufficiently receive the water flow possibly generated from the surface of the first volute 12, and the distance between the first water baffle 31 and the extension 231 of the fan 23 is reduced, so as to prevent the water splash generated in the process of dropping water from splashing to the extension 231.

In one embodiment, the first splash plate 31 includes a guide slope 311, and the guide slope 311 gradually extends downward from the free end of the first splash plate 31 toward the root. That is, the guide slope 311 has an angle with the axial direction of the blower 23, and the angle of inclination may be 15 ° to 30 °.

Thus, the guide slope 311 has a guiding function so that the falling water droplets can be collected toward the end face of the volute and the falling water droplets are prevented from being splashed in a direction away from the second volute 22.

In another embodiment, the first splash plate 31 includes an upwardly open recess 312. In other words, the first splash plate 31 may be provided only with the groove 312.
