[0026] Air duct sealing assembly 100, evaporator 200, base 300, water channel 3001

[0027] First rib 1, connecting section 11, blocking section 12, second rib 2, water guide plate 3, water outlet 4, motor cover 5, third rib 6 Specific embodiments

[0028] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0029] As Figure 1 shown, the air duct sealing assembly 100 of the embodiment of the present disclosure includes a first rib 1 and a second rib 2. The first rib 1 and the second rib 2 are located between the evaporator 200 and the base 300, and the first rib 1 and the second rib 2 are located on the side adjacent to the motor. The base 300 has a water channel 3001 inside. Both the first rib 1 and the second rib 2 are located inside the water channel 3001, and the first rib 1 and the second rib 2 are arranged at intervals in the length direction of the water channel 3001 (such as the left - right direction shown in Figure 2 ). The first rib 1 is adapted to be connected to the motor cover 5, and the second rib 2 is adapted to be connected to the base 300.

[0030] Specifically, as Figure 1 and Figure 2 shown, the air duct sealing assembly 100 is located in the lower right corner of the air duct. The first rib 1 and the second rib 2 are arranged at intervals in the left - right direction, and the first rib 1 and the second rib 2 are arranged at intervals in the front - back direction. The first rib 1 is connected to the motor cover 5, and the side of the first rib 1 away from the motor cover 5 extends into the water channel 3001. The second rib 2 is connected to the base 300, and the second rib 2 extends from the front to the back in the direction approaching the motor cover 5.

[0031] In the air duct sealing assembly 100 of the embodiment of the present disclosure, the first rib 1 and the second rib 2 are located in the gap between the evaporator 200 and the base 300. A labyrinth seal structure is formed by the first rib 1 and the second rib 2, so that external air can be prevented from entering the air duct between the evaporator 200 and the base 300, reducing the risk of condensation.

[0032] In some embodiments, the number of the second ribs 2 is multiple, and the multiple second ribs 2 are arranged at intervals in the length direction of the water channel 3001.

[0033] For example, multiple second retaining ribs 2 all extend in the front-rear direction towards the motor cover 5, and the multiple second retaining ribs 2 are arranged at intervals in the left-right direction. The inclination angles and dimensions of the multiple second retaining ribs 2 in the front-rear direction are the same, or the dimensions of the multiple second retaining ribs 2 in the front-rear direction are staggered in height to form a labyrinth seal, improving the sealing performance of the air duct.

[0034] In some embodiments, the air duct sealing assembly further includes a third retaining rib 6. The third retaining rib 6 extends along the length direction of the water channel 3001, and the third retaining rib 6 and the second retaining rib 2 are arranged at intervals in the width direction of the water channel 3001.

[0035] Specifically, as Figure 6 shown, the third retaining rib 6 extends along the left-right direction, and the third retaining rib 6 and the second retaining rib 2 are arranged at intervals in the front-rear direction. The left end of the third retaining rib 6 is connected to the first retaining rib 1, and the third retaining rib 6 is arranged obliquely downward from front to back. By providing the third retaining rib 6, external air can be blocked from entering the air duct in the front-rear direction, improving the sealing performance of the air duct.

[0036] It should be noted that the third retaining rib 6 is integrally formed with the motor cover, improving the structural strength of the third retaining rib 6.

[0037] In some embodiments, the first retaining rib 1 is integrally formed with the motor cover 5, and / or the second retaining rib 2 is integrally formed with the base 300. Integrally forming the first retaining rib 1 with the motor cover 5 can improve the structural strength of the first retaining rib 1, and integrally forming the second retaining rib 2 with the base 300 can improve the structural strength of the second retaining rib 2.

[0038] The air conditioner according to the embodiments of the present disclosure includes a base 300, an evaporator 200, and an air duct sealing assembly 100. The base 300 has a water channel 3001 inside. The evaporator 200 is connected to the base 300. The air duct sealing assembly 100 is arranged in the water channel 3001. The air duct sealing assembly 100 is located between the base 300 and the evaporator 200, and the air duct sealing assembly 100 is located on the side adjacent to the motor. The air duct sealing assembly 100 is the air duct sealing assembly 100 in any of the above embodiments.

[0039] Specifically, as Figure 2 shown, the evaporator 200 is connected to the base 300. A motor and a motor cover 5 are provided on the right side of the evaporator 200. The base 300 has a water channel 3001 extending along the left-right direction inside. The first retaining rib 1 and the second retaining rib 2 are located in the water channel 3001. The first retaining rib 1 and the second retaining rib 2 are both located on the right side of the water channel 3001, and the first retaining rib 1 and the second retaining rib 2 are located below the motor.

[0040] The air conditioner according to the embodiments of the present disclosure forms a labyrinth seal structure through the first rib 1 and the second rib 2, thereby avoiding the entry of external air into the air duct between the evaporator 200 and the base 300 and reducing the potential risk of condensation in the air conditioner.

[0041] In some embodiments, the first rib 1 includes a connecting section 11 and a blocking section 12. There is an angle between the connecting section 11 and the blocking section 12. The connecting section 11 is connected to the motor cover 5, and the blocking section 12 extends towards the second rib 2.

[0042] Specifically, as Figures 3 to 5 shown, the rear side of the connecting section 11 is connected to the motor cover 5, the front side of the connecting section 11 is connected to the blocking section 12, the blocking section 12 extends in the left-right direction, and there is an angle between the blocking section 12 and the connecting section 11. For example, the angle can be 60°, 70°, 80° or 90°.

[0043] In some embodiments, there is a first preset gap A between the end face of the third rib 6 away from the motor cover 5 and the inner bottom surface of the base 300, and 3 mm ≤ A ≤ 8 mm.

[0044] Specifically, as Figure 7 shown, there is a first preset gap between the lower end face of the third rib 6 and the inner bottom surface of the base 300. By setting the first preset gap, the condensed water in the water channel 3001 can be discharged smoothly, avoiding the accumulation of dust and foreign matters in the water, which may cause drainage blockage at the air duct sealing assembly.

[0045] For example, the first preset gap A can be 3 mm, 4 mm, 5 m, 6 mm, 7 mm or 8 mm.

[0046] Specifically, as Figure 6 shown, when the first preset gap A is less than 3 mm, the gap is too small, resulting in the inability to discharge water smoothly. When the first preset gap A is greater than 8 mm, the gap is too large, affecting the sealing performance of the air duct.

[0047] In some embodiments, the air conditioner further includes a water guide plate 3. The water guide plate 3 is arranged in the water channel 3001 and is located on the side away from the first rib 1. The water guide plate 3 is inclined in the extending direction of the water channel 3001.

[0048] Specifically, as Figure 3 and Figure 4 shown, the water guide plate 3 is located to the right of the second rib 2, and there is a gap between the left end face of the water guide plate 3 and the right end face of the second rib 2. The water guide plate 3 is inclined in the left-right direction. By setting the inclined water guide plate 3, the water on the right side of the water channel 3001 can be diverted to the left side, avoiding the accumulation of water in the water channel 3001.

[0049] In some embodiments, there is a second preset gap B between the water guide plate 3 and the second retaining rib 2, and 3 mm ≤ B ≤ 8 mm.

[0050] Specifically, as Figure 4 shown, there is a second preset gap B between the left end face of the water guide plate 3 and the right side face of the second retaining rib 2, and the second preset gap B can be 3 mm, 4 mm, 5 m, 6 mm, 7 mm or 8 mm. When the second preset gap B is less than 3 mm, it is easy for dust and foreign matters to accumulate at the connection between the water guide plate 3 and the second retaining rib 2 in the condensed water, resulting in blocked drainage. When the second preset gap B is greater than 8 mm, the gap between the water guide plate 3 and the second retaining rib 2 is too large, affecting the air duct sealing performance.

[0051] In some embodiments, the water channel 3001 has a water outlet 4 on the side away from the water guide plate 3, and the water guide plate 3 extends in the direction close to the water outlet 4 along the extending direction of the water channel 3001.

[0052] Specifically, as Figure 3 shown, the water channel 3001 has a water outlet 4 on the left side. One side of the water outlet 4 is communicated with the water channel 3001, and the other side of the water outlet 4 is communicated with an external drain pipe. The water guide plate 3 is arranged in an inclined manner with the right side higher than the left side in the left-right direction, so as to divert the water on the right side of the water channel 3001 to the water outlet 4, avoiding water accumulation in the water channel 3001.

[0053] In some embodiments, the water guide plate 3 and the base 300 are integrally formed. Integrally forming the water guide plate 3 and the base 300 can improve the structural strength of the water guide plate 3.
