Description

Technical Field

[0001] This utility model relates to the field of air conditioner chassis technology, and more specifically, to a drainage structure for a mobile air conditioner chassis. Background Technology

[0002] Currently, some portable air conditioner chassis adopt a partitioned structure, such as a condensate circulation area, a water pumping area, and a return area. Different areas are separated by partitions, allowing condensate to flow in an orderly manner between the areas to achieve specific functions. The drainage structure of the portable air conditioner chassis is particularly important.

[0003] During operation, the condensate produced by the condenser of existing portable air conditioners flows downwards along the end plate. Due to the lack of an effective water flow blocking structure in the end plate, some of the condensate flows along the end plate towards the water pump motor. At the same time, the cross-section of its drainage path is small, and when the condensate flows, the water flow speed is fast and splashing is easy to occur. In addition, the water stays in the chassis for a long time, resulting in low drainage efficiency and potentially causing chassis leakage. This not only affects the normal use of the air conditioner, but may also cause electrical malfunctions due to water contact with electrical components. Utility Model Content

[0004] In order to overcome the problems and defects in the prior art, this utility model provides a drainage structure for a mobile air conditioner chassis to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for a mobile air conditioner chassis, including an air conditioner chassis body, wherein a compressor connecting pipe and an end plate are provided on the top of the air conditioner chassis body, and a drain pipe is fixedly connected to one side of the air conditioner chassis body;

[0006] The connection between the drain pipe and the air conditioner chassis body is fixedly provided with a rounded corner structure, and a rib is provided on one side of the end plate.

[0007] Preferably, the compressor connecting pipe is provided with a plurality of surrounding ribs on its outer side, and the plurality of surrounding ribs are fixedly connected to the air conditioner chassis body. A connecting groove is formed between the plurality of surrounding ribs, and the compressor connecting pipe is installed inside the connecting groove.

[0008] Preferably, the ribs are arranged on the air conditioner chassis body along the drainage direction, and the ribs are treated with adhesive reduction.

[0009] Preferably, the radius of the rounded corner structure is 0.5-2mm, and the center of the rounded corner structure is located at the connection between the drain pipe and the air conditioner chassis body.

[0010] Preferably, the surrounding rib is treated with adhesive reduction at the corresponding position of the compressor connecting pipe, and the area treated with adhesive reduction is the inner sidewall of the surrounding rib.

[0011] Preferably, the rib on one side of the end plate is integrally formed with the air conditioner chassis body, and the cross-sectional shape of the rib is a right trapezoid, with its right-angled side fixedly connected to the end plate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. When the condensate produced by the condenser flows downward along the end plate and toward the water pump motor, the ribs can effectively block the original water flow path, forcing the water flow along the inclined edge of the ribs toward the drainage area at the edge of the chassis, preventing the water flow from contacting the water pump motor, thereby solving the chassis leakage problem, improving the reliability and safety of the portable air conditioner, and avoiding electrical failures and equipment damage caused by water leakage. The ribs on the air conditioner chassis body along the drainage direction are treated with reduced glue, which forms a guide groove after the glue reduction treatment, expanding the cross-section of the drainage path, effectively reducing the residence time of the water flow in the air conditioner chassis body, significantly improving drainage efficiency, ensuring that the condensate can be discharged in a timely and fast manner, and preventing water accumulation in the chassis from affecting the normal operation of the portable air conditioner.

[0014] 2. The rounded corner structure can evenly distribute the concentrated stress generated at the root of the drain outlet during a drop to the surrounding area, eliminating the problem of stress concentration at right-angled edges, enhancing the impact resistance of this part, effectively preventing the root of the drain outlet from turning white and cracking during a drop, improving the structural strength and durability of the drainage structure of the portable air conditioner chassis, and extending the service life of the portable air conditioner.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5 The drainage structure of the mobile air conditioner chassis shown includes an air conditioner chassis body 1, a compressor connecting pipe 2 and an end plate 3 on the top of the air conditioner chassis body 1, and a drain pipe 4 fixedly connected to one side of the air conditioner chassis body 1.

[0023] A rounded corner structure 5 is fixedly installed at the connection between the drain pipe 4 and the air conditioner chassis body 1, and a rib 6 is provided on one side of the end plate 3.

[0024] As shown in the attached figure, multiple surrounding ribs 7 are provided on the outside of the compressor connecting pipe 2. The multiple surrounding ribs 7 are fixedly connected to the air conditioner chassis body 1. A connecting groove 8 is formed between the multiple surrounding ribs 7. The compressor connecting pipe 2 is installed inside the connecting groove 8. The multiple surrounding ribs 7 ensure the installation effect with the compressor connecting pipe 2.

[0025] As attached Figure 1 , 3 As shown in Figure 5, the reinforcing ribs 6 are set on the air conditioner chassis body 1 along the drainage direction. The reinforcing ribs 6 are treated with adhesive reduction to increase the cross-section of the drainage path and reduce the water flow speed, thus avoiding splashing caused by rapid water flow.

[0026] As attached Figure 1-4 As shown, the radius of the rounded corner structure 5 is 0.5-2mm. The center of the rounded corner structure 5 is located at the connection between the drain pipe 4 and the air conditioning chassis body 1. It can evenly distribute the concentrated stress generated at the root of the drain outlet to the surrounding area, eliminate the problem of stress concentration at right angle edges, and enhance the impact resistance of this part.

[0027] As attached Figure 1-3 As shown, the surrounding rib 7 is treated with adhesive reduction at the corresponding position of the compressor connecting pipe 2. The adhesive reduction treatment is performed on the inner side wall of the surrounding rib 7. The adhesive reduction treatment of the surrounding rib 7 increases the buffer space between the compressor and the chassis, preventing the compressor from directly colliding with the chassis when falling.

[0028] As attached Figure 1 , 3 As shown in Figure 5, the rib 6 on one side of the end plate 3 is integrally formed with the air conditioning chassis body 1. The cross-sectional shape of the rib 6 is a right trapezoid, and its right-angled side is fixedly connected to the end plate 3 to improve the strength of the overall drainage structure.

[0029] The working principle of this utility model is as follows: The drainage structure of the mobile air conditioner chassis uses the air conditioner chassis body 1 as the basic load-bearing frame. The end plate 3 at the top and the drain pipe 4 form the basic drainage path. With the flow guiding design of the ribs 6 and the strength optimization of the rounded corner structure 5, the drainage efficiency and structural strength are improved. When the condensate generated by the condenser flows downward along the end plate 3, the ribs 6 on one side of the end plate 3 change the direction of water flow by physical obstruction, guiding the water flow to converge towards the drain pipe 4. The ribs 6 in the drainage direction form a flow guide groove after the glue reduction treatment, which expands the cross-sectional area of ​​the water flow channel and reduces the drainage resistance. The rounded corner structure 5 at the connection between the drain pipe 4 and the chassis body 1 eliminates the right angle edge, reduces the stress concentration phenomenon when falling, and avoids the root of the drain outlet from whitening and cracking. When the condensate flows along the end plate 3 to the water pump motor, the ribs 6 block the original water flow path, forcing the water flow to flow along the inclined edge of the ribs 6 to the drainage area of ​​the chassis edge, avoiding water leakage caused by the water flow contacting the water pump motor. This structure is integrally formed with the air conditioner chassis body 1 to ensure the stability of the water blocking strength.

[0030] After the adhesive reduction treatment, the cross-section of the drainage path is increased and the water flow speed is reduced, avoiding splashing caused by rapid water flow. At the same time, the water flowing along the rib 6 flows to the drain pipe 4, reducing the residence time of the water in the air conditioner chassis body 1 and improving drainage efficiency. The rounded corner structure 5 uses a rounded transition to evenly distribute the concentrated stress to the surrounding area, enhancing the impact resistance of this part.

[0031] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
