[0045] refer to Figures 1 to 8 The present invention proposes a drain box 500 for a window air conditioner, the window air conditioner including an air conditioner housing 100 and a chassis, the chassis being provided with a drain connector 410.

[0046] In one embodiment of the present invention, the drainage box 500 includes:

[0047] The box body 510 is provided with a drain cavity 511, an insertion port 512 and a drain outlet 513 communicating with the drain cavity 511. The box body 510 is used to connect with the air conditioner housing 100, and the insertion port 512 is arranged facing the inside of the air conditioner housing 100. The drain outlet 513 is used to communicate with an external drain pipe 700.

[0048] After the chassis is pushed into the air conditioner housing 100, the drain connector 410 is inserted into the insertion port 512.

[0049] In the technical solution of the present invention, there is no obstruction of the drain pipe 700 during the process of pushing the chassis into the air conditioner housing 100. In this way, the chassis can be smoothly pushed into the air conditioner housing 100 from the indoor side of the window air conditioner to the outdoor side. After the chassis is pushed into the air conditioner housing 100, the drain connector 410 on the chassis extends into the insertion port 512. In this way, the condensate can flow through the drain connector 410, the drain chamber 511 and the drain pipe 700 in sequence to complete the discharge of the condensate.

[0050] It is worth mentioning that, firstly, the drain connector 410 only needs to be inserted into the insertion port 512. The drain connector 410 does not need to be assembled with the insertion port 512. Even if the position of the drain connector 410 and the insertion port 512 is slightly offset, it will not affect the insertion connector from being inserted into the insertion port 512. The processing and installation requirements for the chassis, drain connector 410 and drain box 500 are low, which helps to save costs.

[0051] Secondly, condensate flows from drain connector 410 into drain chamber 511, which is equivalent to condensate flowing from a smaller space into a larger space. If the amount of condensate discharged from drain connector 410 per unit time is large, the condensate in drain chamber 511 will rise slowly and will not directly cover drain outlet 513, which is conducive to the discharge of condensate. Based on life experience, it can be understood that if water directly covers drain outlet 513, since drain outlet 513 still contains air, drain outlet 513 will make a gurgling sound, which is a very poor experience for users. In addition, the air conditioner will also obstruct the condensate, making it difficult for the condensate to drain smoothly.

[0052] Finally, since the drain connector 410 extends into the insertion port 512, which is connected to the external environment, the air pressure at both ends of the drain pipe 700 connected to the drain chamber 511 is equal, so that the condensate can flow out smoothly.

[0053] Optionally, in one embodiment, the box body 510 includes an upper box portion 520 and a lower box portion 530 that are spliced ​​together. The separate splicing arrangement is beneficial to the manufacturing of the box body 510, and the upper and lower splicing method ensures that there are no splicing gaps at the bottom of the box body 510 that are prone to water leakage, which is beneficial to the box body 510 in preventing water leakage.

[0054] Specifically, the insertion port 512 is jointly limited by the upper box portion 520 and the lower box portion 530; the drain port 513 is located in the lower box portion 530, which is connected to the air conditioner housing 100.

[0055] However, this design is not limited to this. In other embodiments, the box body 510 is a one-piece molded component, which improves the structural stability of the box body 510.

[0056] Optionally, in one embodiment, the lower box portion 530 and the upper box portion 520 are detachably connected. This detachable connection facilitates replacement of the upper box portion 520 and the lower box portion 530 when damaged, eliminating the need to replace the entire drain box 500, thus saving costs and also facilitating cleaning of the receiving cavity 320 of the box body 510. However, this design is not limited to this. In other embodiments, the lower box portion 530 and the upper box portion 520 can also be connected by welding or bonding.

[0057] Optionally, in one embodiment, the upper box portion 520 includes an upper box body and an extension portion 521 extending downward from the lower end of the upper box body. The extension portion 521 covers the outside of the lower box portion 530, thereby restricting the relative movement of the upper box portion 520 and the lower box portion 530 in the lateral direction.

[0058] The outer surface of the lower box portion 530 is provided with a limiting rib 531 extending in the lateral direction, and the extension portion 521 is provided with a limiting notch 522 corresponding to the limiting rib 531, thereby restricting the relative movement of the upper box portion 520 and the lower box portion 530 in the vertical direction.

[0059] The lower end of the upper box is provided with a downward-facing buckle 523, which is engaged with the upper edge of the inner surface of the lower box 530, thereby restricting the relative movement of the lower box 530 towards the indoor side of the window air conditioner and towards the outdoor side of the air conditioner.

[0060] By limiting the upper box portion 520 and the lower box portion 530, the upper box portion 520 and the lower box portion 530 have good structural stability after assembly.

[0061] Optionally, in one embodiment, the box body 510 is provided with a detachable structure 540 for connecting with the air conditioner housing 100. The detachable connection makes it convenient to replace the box body 510 and the air conditioner housing 100 when they are damaged, without having to replace the box body 510 and the air conditioner housing 100 together, which helps to save costs. However, this design is not limited to this. In other embodiments, the box body 510 and the air conditioner housing 100 can also be connected by welding or bonding.

[0062] Optionally, in one embodiment, the detachable structure 540 includes a mounting lug 541 located on the outside of the box body 510. The mounting lug 541 has a mounting hole 542 for fasteners to pass through. In this way, the box body 510 is securely connected to the air conditioner housing 100. Specifically, the mounting lug 541 is located in the lower box portion 530, which avoids the lower box portion 530 from having a mounting hole 542 for connection with the air conditioner housing 100, thus ensuring the structural strength of the lower box portion 530. The fasteners may be, but are not limited to, screws or bolts.

[0063] Optionally, refer to as well. Figure 15 In one embodiment, the detachable structure 540 includes a mounting groove 543 disposed on the outer surface of the box body 510. The mounting groove 543 is used for the edge of the air conditioner housing 100 to be fitted and fitted, so that the box body 510 can be disassembled and installed on the air conditioner housing 100. Specifically, the air conditioner housing 100 is provided with a positioning groove 223 corresponding to the box body 510, and the part fitted and fitted into the mounting groove 543 is the edge of the positioning groove 223.

[0064] Optionally, in one embodiment, the drain box 500 further includes an adapter 550 connected to the drain outlet 513, and an external drain pipe 700 connected to the adapter 550. In this way, the position of the drain pipe 700 can be adjusted by the adapter 550. In addition, different diameter drain pipes 700 can be adapted by replacing different adapters 550.

[0065] Optionally, in one embodiment, the adapter 550 and the drain outlet 513 are detachably connected. This detachable connection facilitates replacement of both the adapter 550 and the housing body 510 when damaged, eliminating the need to replace both the housing body 510 and the adapter 550 together, thus saving costs. However, this design is not limited to this; in other embodiments, the drain outlet 513 and the adapter 550 can also be connected by welding.

[0066] Optionally, in one embodiment, the outer surface of the drain outlet 513 is provided with a mounting protrusion 514, and the adapter 550 is provided with a mounting hole 551 corresponding to the mounting protrusion 514. The mounting protrusion 514 is adapted to be engaged with the mounting hole 551. The connection between the mounting protrusion 514 and the mounting hole 551 is simple, convenient and not easy to detach. It is only necessary to push the mounting protrusion 514 into the mounting hole 551, which facilitates the installation of the drain outlet 513 and the adapter 550.

[0067] However, this design is not limited to this. In other embodiments, the drain outlet 513 and the adapter 550 can also be connected by an interference fit.

[0068] The present invention also proposes a window air conditioner, which includes the aforementioned drain box 500. The specific structure of the drain box 500 is as described in the above embodiments. Since the present window air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0069] Window air conditioners also include, for example Figure 8 The air conditioner casing shown here will not be described in detail.

[0070] Reference Figures 9 to 16 The window air conditioner further includes an air conditioner housing 100, a chassis, and an air conditioner body mounted on the chassis, characterized in that the air conditioner housing 100 includes:

[0071] Bottom shell 200; and

[0072] The shell body 300 is detachably connected to the bottom shell 200. The shell body 300 forms a receiving cavity 320 and an installation port 310 communicating with the receiving cavity 320. The installation port 310 is used for inserting and installing the chassis and the air conditioner body.

[0073] In the technical solution of the present invention, the bottom shell 200 and the shell body 300 are detachably connected. After the bottom shell 200 and the shell body 300 are separated, at least the side of the shell body 300 near the bottom shell 200 will expose the opening of the receiving cavity 320. In this way, the space of the receiving cavity 320, which is difficult to use before the bottom shell 200 and the shell body 300 are separated, can be fully utilized. It is understood that if multiple air conditioner shells 100 that have not been separated are transported, a large number of unused receiving cavities 320 will occupy the transport space, which is not convenient for transporting the air conditioner shells 100. In addition, the shell body 300 and the bottom shell 200 are detachable, which is beneficial for replacing the corresponding new parts when one of them is damaged, without having to replace the entire air conditioner shell 100, which facilitates maintenance.

[0074] Optionally, in one embodiment, the shell body 300 and the bottom shell 200 are screwed together. Screw fastening ensures a secure installation of the shell body 300 and the bottom shell 200. The screws are embedded in the components, allowing for the application of a large torque and resulting in high connection strength. However, this design is not limited to this; in other embodiments, the shell body 300 and the bottom shell 200 can be connected by snap-fit ​​connections.

[0075] Optionally, in one embodiment, the bottom shell 200 is frame-shaped. This reduces the amount of material used to form the bottom shell 200, saving costs, and also lightens its weight for easier assembly with the shell body 300. However, this design is not limited to this. In other embodiments, the bottom shell 200 is plate-shaped, resulting in higher structural stability.

[0076] Optionally, in one embodiment, the bottom shell 200 includes two opposing first mounting plates 210 and two opposing second mounting plates 220. Each of the first mounting plates 210 has two corresponding connections to the two second mounting plates 220. The shell body 300 is detachably connected to the first mounting plates 210, thus ensuring a stable installation after the shell body 300 is assembled onto the bottom shell 200. However, this design is not limited to this. In other embodiments, the shell body 300 can be assembled with the bottom shell 200 in other ways, as long as the shell body 300 and the bottom shell 200 are securely installed.

[0077] Optionally, in one embodiment, the two first mounting plates 210 and the two second mounting plates 220 are integrally formed, so that the bottom shell 200 can be integrally formed by a mold, and the integrally formed bottom shell 200 has high strength and extends the service life of the bottom shell 200.

[0078] Optionally, in one embodiment, the two first mounting plates 210 and the two second mounting plates 220 are configured as separate components. In this way, the process quota for producing the first mounting plate 210 and the second mounting part is small, which can greatly reduce the production cost. In addition, separate components are also convenient for transportation.

[0079] Optionally, in one embodiment, the two first mounting plates 210 and the two second mounting plates 220 are connected by welding. It is understood that welding has a very low cost, which helps to reduce the cost of producing the bottom shell 200, and the bottom shell 200 obtained by welding also has high structural strength. However, this design is not limited to this. In other embodiments, the two first mounting plates 210 and the two second mounting plates 220 are connected by screw fastening.

[0080] Optionally, in one embodiment, one of the first mounting plate 210 and the second mounting plate 220 is provided with a positioning protrusion 221, and the other is provided with a positioning slot 211 that cooperates with the positioning protrusion 221. The positioning protrusion 221 and the positioning slot cooperate to assemble the first mounting plate 210 and the second mounting plate 220 into the shape of the bottom shell 200. Then, the first mounting plate 210 and the second mounting plate 220 are connected by welding to ensure that each welded bottom shell 200 has the same shape, which is beneficial for mass production of the bottom shell 200. However, this design is not limited to this. In other embodiments, the first mounting plate 210 and the second mounting plate 220 can be positioned in other ways, as long as the positioned first mounting plate 210 and the second mounting plate 220 can be assembled into the shape of the bottom shell 200.

[0081] Optionally, in one embodiment, the positioning protrusion 221 is provided on the second mounting plate 220. The positioning protrusion 221 is formed by stamping. It can be understood that the positioning protrusion 221 is part of the sheet material of the second mounting plate 220 and is not made by processing additional materials. This helps the second mounting plate 220 to maintain a lighter weight, making the overall weight of the air conditioner housing 100 lighter.

[0082] Optionally, in one embodiment, the second mounting plate 220 has a positioning protrusion 221 at each end of its length, and the first mounting plate 210 has a positioning slot 211 at each end of its length. Thus, the bottom shell 200 and rectangle formed by the first mounting plate 210 and the second mounting plate 220 are relatively regular, which is beneficial for adapting to most chassis. However, this design is not limited to this. In other embodiments, the first mounting plate 210 has a positioning protrusion 221 at each end of its length, and the second mounting plate 220 has a positioning slot 211 at each end of its length.

[0083] Optionally, in one embodiment, the shell body 300 includes two side plates 330 and a top plate 340 connecting the two side plates 330. The two side plates 330 and the top plate 340 enclose the mounting opening 310 and the receiving cavity 320. The side plates 330 are detachably connected to the bottom shell 200. The bottom shell 200 has a limiting flange 222 on its side edge away from the mounting opening 310. During the insertion and installation of the chassis and the air conditioner body, the chassis abuts against the limiting flange 222. The user can feel that the chassis is installed in place when it abuts against the limiting flange 222, which is very convenient. In addition, it can be understood that the shell body 300 formed by the top plate 340 and the two side plates 330 has an opening opposite to the mounting opening 310. The limiting flange 222 can also prevent the chassis and the air conditioner body from sliding out of the opening. Specifically, in one embodiment, the limiting flange 222 is located on the second mounting plate 220.

[0084] It should be noted that the positioning groove 223 of the air conditioner housing 100 mentioned above is located on the limiting flange 222.

[0085] Specifically, in one embodiment, both first mounting plates 210 have upwardly extending flanges, one flange being screwed to a corresponding side plate 330, and the flanges are provided with a plurality of screw fastening points 212, specifically, there are four screw fastening points 212.

[0086] Optionally, in one embodiment, the bottom shell 200 is provided with a guide rail 213 extending along the mounting opening 310. This allows the air conditioner unit to slide into the receiving cavity 320 along the guide rail 213, which is very convenient. Specifically, in one embodiment, two guide rails 213 are provided, located on both sides of the bottom shell 200, which makes the chassis slide more smoothly. Specifically, in one embodiment, the guide rail 213 is located on the first mounting plate 210.

[0087] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
