Fig. 1 shows a preferred embodiment of an air conditioner indoor unit according to the present invention. As shown in FIG. 1 , the air-conditioning indoor unit includes an air-conditioning indoor unit housing, an air supply device 10 and an evaporator 20, wherein the air-conditioning indoor unit housing includes a front shell, and the front shell includes a housing configured to accommodate the evaporator 20. The surface frame 40 of the accommodating chamber, the inner wall of the surface frame 40 is provided with a water receiving structure for catching the condensed water rolling down from the surface of the evaporator 20 and guiding it back to the evaporator 20 .

Specifically, as shown in FIG. 1 and FIG. 2, the evaporator 20 is arranged in the accommodating chamber and is roughly "U"-shaped, and the "U"-shaped evaporator includes a first heat exchange part 21, a second heat exchange part 22 and the third heat exchange part, the second heat exchange part 22 is connected to one end of the first heat exchange part 21 in an angled manner, and the third heat exchange part 23 is connected to the first heat exchange part 21 in an angled manner The other end, wherein, the first heat exchange part 21 is located above the air supply device 10, and the second heat exchange part 22 and the third heat exchange part are respectively located on the left and right sides of the air supply device 10. Due to space and heat exchange requirements, the upper surface of the first heat exchange part 21 of the evaporator 20 usually needs to be inclined at a certain angle. The water on the surface of the evaporator, due to the inclusion of dust and other substances, will roll off when the diameter of the water droplets is estimated to be about 4mm. Therefore, water droplets of about 4 mm will roll down along the upper surface of the first heat exchange part 21 of the evaporator 20 (the trajectory of which is shown by the dotted line in Figure 2 ), and due to the effect of the acceleration of gravity, the water droplets can easily escape from evaporation. device, there is a phenomenon of water leakage. In order to avoid water leakage, the inner wall surface of the surface frame 40 is located on the extension line of the movement track of the condensed water on the surface of the first heat exchange part 21 of the evaporator 20. There is a set for catching the condensation falling from the surface of the evaporator 20. The water is sent back to the water receiving structure 30 of the evaporator 20 .

According to the air-conditioning indoor unit of the embodiment of the present invention, the water receiving structure 30 for catching the condensed water falling from the surface of the evaporator 20 and guiding it back to the evaporator 20 can be effectively avoided by setting the inner wall of the surface frame 40 The condensed water in the first heat exchange part 21 of the evaporator 20 rolls off and leaks out.

In some embodiments of the present invention, the water receiving structure 30 can be integrally formed with the surface frame 40 , or can be fixed on the inner wall of the surface frame 40 by pasting.

Specifically, as shown in FIG. 2 and FIG. 4 , the water-receiving structure 30 includes a first folded surface 31 in a substantially vertical direction and a second folded surface connected to the lower end of the first folded surface 31 and extending away from the inner wall surface of the surface frame 40 . Two folding surfaces 32. Further, the gap between the lower end of the second folding surface 32 and the second heat exchange part 22 of the evaporator 20 is less than or equal to 4mm. When the condensed water on the upper surface of the first heat exchange part 21 of the evaporator 20 condenses to a diameter of about 4 mm, it rolls down, and reaches the first folding surface 31 of the water receiving structure 30 along its motion track, and then from the second One folding surface 31 flows to the second folding surface 32 , and enters the second heat exchange part 22 of the evaporator 20 from the lower end of the second folding surface 32 . Because the gap between the second folded surface 32 and the evaporator 20 is less than or equal to 4 mm, the condensed water can be effectively prevented from leaking from between the second heat exchange part 22 of the evaporator 20 and the second folded surface 32 .

It should be noted that the second folded surface 32 is continuous and the second folded surface 32 should be higher than the ribs on the front panel for supporting the filter, so as to prevent condensed water from leaking along the ribs.

Further, as shown in Fig. 5, Fig. 6 and Fig. 7, water retaining parts 34 are respectively provided at the left and right ends of the water receiving structure 30 to prevent the condensed water from flowing along the surface frame due to the inclination of the indoor unit of the air conditioner in the length direction. The inner wall surface of 40 flows out and causes water leakage phenomenon.

In addition, the second folded surface 32 extends obliquely downwards, and the included angle with the horizontal plane is greater than or equal to 5°, so as to prevent the indoor unit of the air conditioner from being tilted due to installation, and the condensed water cannot be sent back to the second heat exchange part of the evaporator 20 in time. Within 22.

Further, in order to ensure that the water receiving structure 30 can completely catch the condensed water droplets rolling down from the upper surface of the first heat exchange part 21 and prevent water leakage, the condensed water on the upper surface of the first heat exchange part 21 of the evaporator 20 The height L1 from the intersection point of the extension line of the movement track of the water receiving structure 30 to the upper end of the first folding surface 31 of the water receiving structure 30 is greater than or equal to 4 mm, as shown in FIG. 2 .

Advantageously, in order to prevent condensed water from flying out from the upper end of the water receiving structure 30, the upper end of the first folded surface 31 is provided with a first folded portion 33 that is away from the inner wall surface of the surface frame 40 and extends obliquely upward, as shown in Figure 2 and Figure 4 shows.

The invention also discloses an air conditioner, which comprises the above air conditioner indoor unit.
