Description

Technical Field

[0001] The utility model relates to the field of air conditioners, in particular to an air conditioner, an air conditioner indoor unit and a base drainage structure thereof. Background Art

[0002] When the air conditioner is cooling, a large amount of condensed water will be generated inside it. Therefore, it is particularly important to set up a reasonable drainage structure inside the air conditioner. If the drainage structure inside the air conditioner is not set up reasonably, it will cause the air conditioner to leak and even cause a safety accident. On the indoor unit of the wall-mounted air conditioner, one end of the fan blade is fixed to the motor, and the other end of the fan blade is fixed to the bearing seat. The bearing seat is installed on the base. Due to the structural limitations of the mold, there is often a through hole on the base where the bearing seat is installed, which makes it easy for the through hole to leak. At present, the industry generally chooses to stick thermal insulation cotton at the through hole in order to achieve a sealing effect. However, in the production process, sticking thermal insulation cotton adds a process, which affects the production efficiency of the air conditioner. In addition, the thermal insulation cotton is prone to failure. Long-term use may cause the thermal insulation cotton to break, and the reliability is poor. Utility Model Content

[0028] like Figures 1 to 5As shown, a base body drainage structure includes a base body 1, a through hole 11 is opened on the base body 1 for cooperating with the elastic buckle 21 on the fan blade bearing seat 2, a water channel is arranged at the bottom of the base body 1, a water guide rib 12 is protruded inwardly on the inner wall of the base body 1, the water guide rib 12 is arranged around the through hole 11, a first water retaining rib 13 is arranged on the side of the water guide rib 12 away from the base body 1, the first water retaining rib 13 is arranged around the through hole 11, the width of the first water retaining rib 13 is greater than the width of the water guide rib 12, and a water receiving platform 14 is also protruded inwardly on the inner wall of the base body 1, and the upper surface of the water receiving platform 14 is located below the lower surface of the first water retaining rib 13. In this way, a water guide rib 12 is protruded around the through hole 11 to guide the dripping condensed water, and a first water retaining rib 13 is set on the side of the water guide rib 12 to prevent the condensed water at the water guide rib 12 from flowing to the through hole 11 and causing water leakage. By setting a water receiving platform 14, the condensed water is gathered and drained to the waterway at the bottom of the base body 1.

[0029] like Figure 2 As shown, in the present invention, the lower surface of the water guide rib 12 is flush with the lower surface of the first water retaining rib 13, and the upper surface of the water receiving platform 14 is respectively against the lower surface of the water guide rib 12 and the lower surface of the first water retaining rib 13. In this way, it is ensured that the water at the water guide rib 12 can flow smoothly to the water receiving platform 14 instead of flowing to other places of the base body 1.

[0030] In order to enable the condensed water to drain quickly along the water guide rib 12 and prevent the condensed water at the water guide rib 12 from overflowing over the first water retaining rib 13 to the through hole 11, the difference between the width of the water guide rib 12 and the width of the first water retaining rib 13 is ≥1.5mm.

[0031] When the fan blade bearing seat 2 is installed on the base body 1, part of the water receiving platform 14 is located below the fan blade bearing seat 2. In this way, the condensed water sliding down from the fan blade bearing seat 2 can be gathered along the fan blade bearing seat 2 to the water receiving platform 14 of the base, and flow along the side wall of the water receiving platform 14 to the water channel of the base body 1.

[0032] In order to prevent the condensed water gathered on the upper surface of the water receiving platform 14 from overflowing into the through hole 11, a second water retaining rib 15 is provided at the lower part of the first water retaining rib 13. In order to improve the reliability of the second water retaining rib 15 and prevent the condensed water from overflowing into the through hole 11 due to untimely discharge, the height h1 of the second water retaining rib 15 is ≥2mm.

[0033] In order to obtain a better drainage effect and improve the reliability of the drainage structure, the upper surface of the water receiving platform 14 is inclined downward from the outside to the inside. More preferably, the angle α between the upper surface of the water receiving platform 14 and the horizontal plane is greater than 5°, so that the condensed water gathered on the upper surface of the water receiving platform 14 can quickly flow to the water channel of the base body 1.

[0034] In order to ensure that the elastic buckle 21 of the fan blade bearing seat 2 can be smoothly buckled into the through hole 11 of the base body 1, a buckle guide portion 16 is also protruded inward on the inner wall of the base body 1, and the buckle guide portion 16 is arranged above the through hole 11, and the upper surface of the buckle guide portion 16 is tilted downward from the outside to the inside, and the inner side of the buckle guide portion 16 is connected with the arc transition of the through hole 11. The fan blade bearing seat 2 in the utility model is an existing fan blade bearing seat that can be bought on the market, and a buckle 22 for inserting into the slot 17 on the base body 1 is also provided thereon. During installation, the elastic buckle 21 of the fan blade bearing seat 2 first contacts the upper surface of the buckle guide portion 16 of the base body 1, so that the elastic buckle 21 undergoes elastic deformation, the fan blade bearing seat 2 continues to move downward, the elastic buckle 21 of the fan blade bearing seat 2 is reset, the elastic buckle 21 is buckled into the through hole 11, and the buckle 22 is inserted into the slot 17 of the base body 1, that is, the installation of the fan blade bearing seat 2 is completed.

[0035] In order to obtain a better assembly effect and improve assembly smoothness, the angle β between the upper surface of the snap guide portion 16 and the horizontal plane is 75°>β>45°, so that the elastic buckle 21 of the fan blade bearing seat 2 can be smoothly assembled into the through hole 11 through the upper surface of the snap guide portion 16.

[0036] The utility model also discloses an indoor unit of an air conditioner, comprising the base body drainage structure as described above.
