And the electric control box 2 with the air inlet gap 21 is arranged on one side of the surface frame 11 in the length direction of the surface frame 11, so that part of air can enter the shell 1 from the air inlet gap 21, and the heat dissipation of electric devices in the electric control box 2 is realized. Meanwhile, the filter screen 3 is arranged in the shell 1, the air entering from the first air inlet 101 and the second air inlet 102 is filtered by the filter screen 3, the heat exchanger 4 is arranged at the downstream of the filter screen 3, and the heat exchange treatment is carried out on the air filtered by the filter screen 3 by the heat exchanger 4, so that the heat exchange efficiency of the indoor unit of the air conditioner can be improved to a certain extent.
According to some embodiments of the present invention, as shown in fig. 4, a filter screen 3 is disposed in the housing 1 and located downstream of the first air inlet 101 and the second air inlet 102, for filtering the air entering the housing 1 from the first air inlet 101 and the second air inlet 102 to achieve a subsequent heat exchange process. As a preferred embodiment, the screen 3 may be formed in a multi-fold shape, as shown in fig. 4, the multi-fold shape of the screen 3 is disposed adjacent to the inner wall surface of the housing 1, and the screen 3 may include a plurality of screen surfaces connected in sequence, thereby making the filtering function more excellent.

As shown in fig. 4, a heat exchanger 4 is disposed in the casing 1 downstream of the filter screen 3 to perform a heat exchange process on the air filtered by the filter screen 3. Alternatively, as shown in fig. 3, the heat exchanger 4 may be a multi-fold heat exchanger 4, and at least one fold of the multi-fold heat exchanger 4 may be disposed adjacent to the top mesh surface 31 and the side wall mesh surface 32, so as to exchange heat with the air filtered by the filter screen 3, thereby performing cooling or heating. Preferably, as shown in fig. 4, a portion of the multi-fold heat exchanger 4 may be attached to the front panel 12, so that the air entering the casing 1 from the second air inlet 102 may be directly subjected to heat exchange, which not only further improves the heat exchange efficiency, but also avoids the occurrence of turbulence.

The housing 1 of the indoor unit 100 of the air conditioner according to the embodiment of the present invention will be described in detail with reference to fig. 1 to 10.
As shown in fig. 1 to 3, a first air inlet 101 is formed at the top between the face frame 11 and the front panel 12, and indoor air can be sucked into the air conditioner case 1 through the first air inlet 101 for subsequent heat exchange treatment. In an alternative example shown in fig. 1 to 3, the top protection cover 111 may be disposed on the first air inlet 101, wherein the top protection cover 111 may be formed by a plurality of horizontal bars spaced apart from each other in parallel and a plurality of vertical bars spaced apart from each other in parallel, that is, the top protection cover 111 may be formed in a mesh shape, so as to protect elements inside the air conditioner housing 1 to a certain extent, and prevent impurities with large volume from entering the inside of the housing 1 through the air inlet and affecting the normal operation of the air conditioner.
As a preferred embodiment, as shown in fig. 1-6 in combination with fig. 8, the total area of the plurality of air inlet holes 121 may occupy 30% -50% of the total area of the front panel 12, so as to further improve the aesthetic property of the air conditioner case 1, and at the same time, ensure that the front panel 12 of the air conditioner has sufficient strength to provide a certain protection for the components inside the air conditioner case 1.
According to some embodiments of the present invention, as shown in fig. 1, 4, 6, and 9, the cross-section of the front panel 12 may be formed in an arc shape protruding forward. As shown in fig. 4, since the evaporator and the screen 3 are provided at the upper portion of the inside of the case 1, the total area of the air inlet holes 121 located above the middle horizontal reference line on the front panel 12 may be larger than the total area of the air inlet holes 121 located below the horizontal reference line. In other words, as shown in fig. 2, 6 and 8, if a horizontal reference line (e.g., a dashed line X) divides the front panel 12 into two parts, the total area of the air inlet holes 121 on the front panel 12 near the first air inlet 101 is larger than the total area of the air inlet holes 121 on the front panel 12 far away from the first air inlet 101, so that the second air inlet 102 can assist the first air inlet 101 to suck air, increasing the air inlet amount, increasing the air exchanged by the evaporator, and further improving the air outlet efficiency. Further, the condition that turbulent flow is formed below the heat exchanger 4 accumulated in the shell 1 from the lower air inlet holes 121 is avoided, and in addition, the aesthetic property of the air conditioner shell 1 is improved.

As shown in fig. 1, 2 and 6 in combination with fig. 8, the gap between two adjacent air inlet holes 121 in each row of air inlet holes 121 can gradually increase from top to bottom, that is, the gap between the air inlet holes 121 adjacent to the first air inlet 101 is smaller than the gap between the air inlet holes 121 far away from the first air inlet 101, so that the upper air inlet holes 121 are arranged more densely and the lower air inlet holes 121 are arranged more sparsely, which not only can ensure that the front panel 12 has sufficient strength, but also can make the auxiliary air suction function of the second air inlet 102 better.
Specifically, the area of the first or second air inlet hole 121 from top to bottom of each row of air inlet holes 121 can be set to be the largest, for example, as shown in fig. 9, the area of the first air inlet hole 121 of each row of air inlet holes 121 can be set to be the largest, so that the air inlet amount can be increased to some extent.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the air inlet hole 121 may also be formed as an oval through hole extending in the up-down direction, so as to make the air conditioner indoor unit 100 more attractive.
According to some embodiments of the present invention, as shown in fig. 1, 2 and 6 in combination with fig. 8, the top edges of the rows of air inlet openings 121 may not be on the same horizontal line, and the bottom edges of the rows of air inlet openings 121 may not be on the same horizontal line, that is, the rows of air inlet openings 121 may be staggered in the up-down direction. Further, the plurality of rows of air inlet holes 121 may be arranged to form a shape similar to a frequency spectrum, so that the aesthetic appearance of the front panel 12 may be further improved.
In one specific example of the present invention, as shown in fig. 5, the top wall of the uppermost air inlet hole 121 in each row may be formed as an arc-shaped surface inclined from outside to inside from top to bottom, so that not only the strength of the front panel 12 may be improved, but also the front panel 12 may be more aesthetically pleasing.
In another specific example of the present invention, the top wall of the uppermost air inlet hole 121 in each row may also be formed as a plane inclined from the outside to the inside from the top to the bottom as shown in fig. 8, 9 and 10, thereby improving the strength of the front panel 12 while enhancing the aesthetic appearance thereof.
