Wherein, in order to avoid the comdenstion water of top bending portion department to cross-flow fan 2 whereabouts, set up water receiving tank 5 along the extending direction of top bending portion, and the length dimension of water receiving tank 5 is not less than the length dimension of top bending portion for the comdenstion water of top bending portion homoenergetic falls into water receiving tank 5.

In some embodiments, as shown in fig. 2 and 3, the water receiving member 4 is provided as a water receiving rod. The water receiving rod extends along the length direction of the evaporator 3, and a water receiving groove 5 is formed at one side of the water receiving rod facing the evaporator 3. The water receiving rod is used for collecting condensed water at the top bending part, so that the device is simple in structure, convenient to produce and install, and production cost is reduced.

In other embodiments of the present application, the water receiving member 4 may also be provided as a water receiving plate. The water receiving plate extends along the length direction of the evaporator 3, and a water receiving groove 5 is formed at one side of the water receiving plate facing the evaporator 3. In other embodiments of the present application, the water receiving member 4 may also be provided as a water receiving tube. The water receiving pipe extends along the length direction of the evaporator 3, and a strip-shaped notch is formed on one side of the water receiving pipe facing the evaporator 3 and is matched with the internal channel of the water receiving pipe to jointly form the water receiving groove 5.

Wherein, the water receiving groove 5 can be provided as a U-shaped groove, a V-shaped groove and a calabash-shaped groove. In the present embodiment, the shape of the water receiving tank 5 is not limited, and it is sufficient to ensure that it can receive condensed water dropped from the top end bent portion of the evaporator 3.

Referring to fig. 1 and 6, two ends of the water receiving member 4 are fixed to the base 1 by mounting members 8, each mounting member 8 is configured with a socket 9, and two ends of the water receiving member 4 are respectively inserted into the sockets 9 of the two mounting members 8.

It can be understood that the water receiving piece 4 is fixed between the cross flow fan 2 and the top end bending part 7 by inserting both ends of the water receiving piece 4 into the insertion holes 9 of the two mounting parts 8 respectively. The water receiving piece 4 is installed in a plugging installation mode, so that the water receiving piece 4 is simple to install and easy to maintain.

To prevent rotation of the water receiving member 4, the cross-sectional shape of the socket 9 is non-circular. For example, the socket 9 is provided in a U-shape, V-shape, U-shape, semicircular shape, polygonal shape, or the like. Plugs matched with the shape of the sockets 9 are respectively constructed at the two ends of the water receiving piece 4, and the plugs are inserted into the sockets 9 to realize the assembly between the water receiving piece 4 and the mounting part 8. Alternatively, the socket 9 is in clearance fit with the water receiving piece 4, and both ends of the water receiving piece 4 are abutted with the mounting member 8. Thus, the position stability of the water receiving piece 4 can be improved, and the water receiving piece 4 is effectively prevented from moving left and right or rotating under vibration.

As shown in fig. 6 and 7, one of the mounting members 8 is configured with a drain passage 11 communicating with the socket 9, and the socket 9 communicates with the water receiving tank 5. It will be appreciated that condensate dripping into the water receptacle 4 from the top end bend 7 requires drainage to avoid accumulation of condensate in the water receptacle 5 of the water receptacle 4. By constructing the drain passage 11 in one of the mounting members 8 and allowing the water receiving tank 5, the spigot 9, and the drain passage 11 to communicate in this order, the condensed water in the water receiving tank 5 can be drained along the water receiving tank 5, the spigot 9, and the drain passage 11.

In some embodiments, the mounting members 8 at both ends of the water receiving member 4 are a left end plate and a right end plate of the indoor unit 100, respectively, wherein the right end plate is integrally formed with a motor gland and the like at the right side. Since the motor is mounted on the outer side of the right end plate, the drain passage 11 is provided on the left end plate to prevent the condensed water from entering the motor to damage the motor.

In some embodiments, the socket 9 at the right end plate is a non-through hole to avoid condensate entering the motor and causing damage to the motor. Alternatively, a mounting block 10 may be formed on the side of the right end plate facing the water receiving member 4, and the aforementioned socket 9 located on the right end plate may be formed on the mounting block 10, so that the water receiving member 4 can be mounted, and damage to the motor caused by the condensed water entering the motor can be avoided.

In some embodiments, the drain channel 11 may be configured on the outside of the left end plate (i.e. the side of the left end plate remote from the water receiving member 4), in which case the spigot 9 at the left end plate is a through hole. The structure can enable the drainage channel 11 to be positioned outside the accommodating cavity 6, and prevent condensed water from dripping into the accommodating cavity 6 due to water leakage of the drainage channel 11 and being blown out from the air outlet after passing through the cross-flow fan 2.

As shown in fig. 7, the drain passage 11 on the left end plate includes: drainage ribs 12, rib plates 13 and drainage plates 14. The drainage rib 12 is obliquely arranged, and the upper end of the drainage rib extends to the position of the socket 9 of the left end plate. The rib plate 13 is a structural reinforcing rib provided on the outer side of the left end plate, a water outlet 15 is arranged on the rib plate 13, and the lower end of the drainage rib 12 extends to the position of the water outlet 15.

It will be appreciated that the drain channel 11 is located in the left end plate and the water receiving member 4 is gradually inclined downwardly in the direction from the right end plate to the left end plate so that condensed water dropped into the water receiving tank 5 can be drained from the drain channel 11 of the left end plate.

Based on the inclined arrangement of the water receiving piece 4, an included angle A is formed between the water receiving piece 4 and the horizontal plane, wherein A is more than 0 and less than or equal to 10 degrees. In the present embodiment, the angle a may be set to 1 °, 2 °, or 3 °. The specific angle of the angle a may be set reasonably according to the overall length of the indoor unit 100. Specifically, the longer the overall length, the smaller the value of angle a.

As shown in fig. 4 and 5, the groove depth of the water receiving groove 5 increases in a direction approaching the mounting member 8 provided with the drain passage 11. It is also possible to drain the condensed water dropped into the water receiving tank 5 to one end of the mounting member 8 provided with the drain passage 11 and drain the condensed water from the drain passage 11, preventing the condensed water from accumulating in the water receiving tank 5.

For example, three saddles 16 are arranged, and the three saddles 16 are provided at three points corresponding to four equal-dividing points in the longitudinal direction of the base 1, respectively. The number of saddles 16 is selected reasonably based on the overall length of the indoor unit 100, the deflection of the water receiving element 4, and the number of cross flow fans 2.

In some embodiments, the support unit 17 includes a through hole provided on the saddle 16, and the through hole penetrates in the length direction of the base 1, and the shape of the through hole matches the shape of the water receiving member 4. At this time, the water receiving piece 4 is inserted into the through hole to support the saddle 16 to the water receiving piece 4.
