[0022] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0024] The air inlet assembly according to the embodiment of the present application will be described below in combination with Figure 1 The air inlet assembly according to the embodiment of the present application will be described below in combination with

[0025] The air inlet assembly according to the embodiment of the present application will be described below in combination with

[0026] It should be noted that the grid hole 32 is generally a rectangular hole, and the width direction thereof is the front-rear direction of the air conditioner, and the electrical device includes a display panel and a stepping motor installed on the front panel 11.

[0027] ​In some embodiments, as shown in Figure 1 The air supply channel 2 includes a first channel 21 and a second channel 22 arranged on opposite sides of the evaporator 6 in the width direction of the indoor unit body, and the first channel 21 is provided with electrical components connected to the indoor unit body. The width of the grid hole 32 below the first channel 21 is smaller than the width of the grid hole 32 below the second channel 22.

[0028] The distance between the electrical components in the first channel 21 and the grid hole 32 in the vertical direction is short. By reducing the width of the grid hole 32 below the first channel 21, the fingers of the worker can be prevented from passing through the grid hole 32 below the first channel 21. Even if the fingers of the worker can pass through the grid hole 32 below the second channel 22, the electrical components in the first channel 21 will not be touched by mistake due to the blocking of the evaporator 6. The air inlet area at the air inlet hole 121 is ensured, and the use safety of the air conditioner is further improved. Specifically, the second channel 22 can also be installed with electrical components, and the electrical components in the second channel 22 are higher than the electrical components in the first channel 22.

[0029] In some embodiments, as shown in Figure 1 The width of the grid hole 32 opposite to the first channel 21 in the height direction (vertical direction) of the indoor unit body is a, and 6mm≤a≤12mm. Figure 1

[0030] By setting the width of the grid hole 32 below the first channel 21 to be greater than or equal to 6mm, it is effectively avoided that the arrangement of the spacer ribs constituting the grid assembly is too dense and occupies too large an area of the air inlet hole 121, and the air inlet area at the air inlet hole 121 is effectively ensured. By setting the width of the grid hole 32 below the first channel 21 to be less than or equal to 12mm, it is effectively prevented that the fingers pass through the grid hole 32, or the length of the part of the fingers passing through the grid hole 32 is effectively prevented from being too large to touch the electrical components, and the use safety of the air conditioner is further ensured.

[0031] Specifically, the width of the grid hole 32 below the first channel 21 can be 6mm, 9mm and 12mm.

[0032] In some embodiments, the grid assembly includes a finger guard grid 3, and the finger guard grid 3 includes a plurality of first spacer ribs 31 arranged at intervals in the width direction of the indoor unit body. The distance between any two adjacent first spacer ribs 31 is a.

[0033] The grid assembly forms the grid hole 32 below the first channel 21 through the plurality of first spacer ribs 31 in the finger guard grid 3. At this time, the finger guard grid 3 is arranged in a staggered manner in the front-rear direction with the second channel 22, thereby avoiding that the finger guard grid 3 is distributed below the second channel 22 to affect the air inlet area of the air inlet hole 121. ​

[0034] Specifically, the plurality of first partitioning ribs 31 are arranged equidistantly along the front-rear direction, and the finger guard grid 3 further comprises a horizontal rib extending along the left-right direction of the air conditioner, the horizontal rib connecting two adjacent first partitioning ribs 31, which also effectively improves the structural strength of the finger guard grid 3.

[0035] In some embodiments, the maximum width of the first partitioning rib 31 is b, where 2mm≤b≤5mm.

[0036] This design avoids the maximum width of the first partitioning rib 31 being too small, resulting in poor strength and poor protection, and on the other hand, avoids the maximum width of the first partitioning rib 31 being too large, which affects the air inlet area at the air inlet hole 121 and the air supply efficiency of the air conditioner.

[0037] Specifically, as shown in Figure 1 the maximum width of the first partitioning rib 31 can be 2mm, 4mm and 5mm.

[0038] In some embodiments, the width of the first partitioning rib 31 gradually increases from bottom to top.

[0039] While the maximum width of the first partitioning rib 31 is constant, this setting further reduces the projected area of the first partitioning rib 31 on the projection plane perpendicular to the up-down direction, ensures the air inlet area at the air inlet hole 121, and on the other hand, greatly reduces the wind resistance when the airflow passes through the first partitioning rib 31 when the airflow passes through the finger guard grid 3, the efficiency of the vortex formed by the airflow at the first partitioning rib 31 is lower, and the air supply efficiency of the air conditioner is higher.

[0040] Specifically, the bottom surface of the first partitioning rib 31 is a downwardly concave arc surface, and the projection of the first partitioning rib 31 on the projection plane perpendicular to the left-right direction of the air conditioner is a wedge shape with a wide top and a narrow bottom.

[0041] In some embodiments, the height of the first partitioning rib 31 is c, where 2mm≤c≤8mm.

[0042] By setting the height of the first partitioning rib 31 to be greater than or equal to 2mm, it is ensured that it has sufficient structural strength and ensures its protection reliability, and by setting the height of the first partitioning rib 31 to be less than or equal to 8mm, it effectively avoids the upper surface of the first partitioning rib 31 being too close to the lowest point of the water pan 5, which causes the airflow to be directly guided to the bottom surface of the water pan 5 by the finger guard grid 3, thereby increasing the air inlet resistance.

[0043] Specifically, the height of the first partitioning rib 31 can be 2mm, 5mm and 8mm.

[0044] In some embodiments, as shown in Figure 1As shown, the first partitioning ribs 31 are located below the first channel 21, and the air inlet grille assembly further comprises an air inlet grille 4 which is detachably arranged in the air inlet hole 121. The air inlet grille 4 comprises a plurality of second partitioning ribs 41 which are arranged at intervals along the width direction of the inner unit body. The number of the second partitioning ribs 41 is greater than that of the first partitioning ribs 31, and the second partitioning ribs 41 are located below the first partitioning ribs 31.

[0045] That is, the plurality of grille holes 32 formed by the air inlet grille 4 are partially located below the first channel 21 and partially located below the second channel 22. In this case, the air inlet grille 4 improves the structural strength of the inner unit body at the air inlet hole 121, protects the evaporator 6, the water receiving tray 5 and electrical components in the air supply channel 2, and improves the appearance of the air inlet assembly at the air inlet hole 121. The air inlet grille 4 is detachably connected to the inner unit body, thereby effectively reducing the manufacturing cost of the air inlet grille 4 and facilitating the disassembly of the air inlet grille 4 for cleaning.

[0046] Specifically, the air inlet grille 4 is clamped in the air inlet hole 121, or the air inlet grille 4 is fastened in the air inlet hole 121 by a threaded member. The plurality of second partitioning ribs 41 are arranged at intervals along the front-rear direction. Among the plurality of grille holes 32 formed by the air inlet grille 4, the width of the grille holes 32 located below the first channel 21 is greater than or equal to the width of the grille holes 32 formed by the finger protection grille 3, and the width of the grille holes 32 located below the second channel 22 is greater than the width of the grille holes 32 formed by the finger protection grille 3.

[0047] The air inlet assembly further comprises a filter screen which is detachably arranged in the air inlet hole 121 and located below the grille assembly. The filter screen prevents external dust from entering the air supply channel 2, effectively ensures the cleanliness and hygiene of the components in the air supply channel 2, and greatly prolongs the cleaning cycle of the air conditioner.

[0048] In some embodiments, as shown in the accompanying drawings, Figure 1 As shown, the inner unit body comprises a middle frame 1 which comprises a front panel 11 and a bottom plate 12 connected together. An inner wall surface of the front panel 11 is provided with a mounting position, and the bottom plate 12 is provided with the air inlet hole 121. The front panel 11, the bottom plate 12 and the first partitioning ribs 31 are integrally formed.

[0049] By integrally forming the middle frame 1 and the finger protection grille 3, the number of components of the air conditioner is effectively reduced, the assembly efficiency of the air conditioner is improved, and the connection strength of the bottom plate 12 and the finger protection grille 3 is also effectively improved.

[0050] In some embodiments, the air supply channel 2 is provided with a water receiving tray 5. The distance between the lowest point of the outer wall surface of the water receiving tray 5 and the upper surface of the first partitioning ribs 31 in the height direction of the inner unit body is d, wherein d≥8mm.

[0051] The arrangement avoids the water pan 5 from being too close to the finger guard grid 3 in the up-down direction to block the air inlet hole 121, and the air inlet hole 121 can flow in a larger space to bypass the water pan 5 after passing through the finger guard grid 3, the air flow resistance of the air flow passing through the water pan 5 is smaller, and the air supply efficiency of the air conditioner is higher.

[0052] Specifically, the distance between the lowest point of the outer wall surface of the water pan 5 and the upper surface of the first partition rib 31 in the height direction of the indoor unit body can be 8mm, 10mm and 12mm.
