[0034] To address the issue that traditional air conditioners have drain pipes connected to the frame via screws, making maintenance or cleaning inconvenient and impacting user experience, replacing the indoor unit with an easily removable one is costly. This presents a dilemma for users, making it difficult to strike a balance between convenience and cost savings.
[0035] like Figures 1 to 4As shown, this embodiment discloses an air conditioner. A traditional air conditioner includes an outdoor unit, an indoor unit, and a drain pipe. The drain pipe is a conventional drain pipe. The outdoor unit is installed outdoors, and the indoor unit is installed indoors. The outdoor unit and the indoor unit are connected through a refrigerant circulation pipeline. The indoor unit includes a frame 1 and a short drain pipe 2. A water storage chamber for condensate is formed on the frame 1. The short drain pipe 2 is integrally formed on the frame 1 and connected to the bottom of the water storage chamber, so that the condensate generated during the operation of the air conditioner can be discharged more smoothly through the short drain pipe 2.
[0036] The frame 1 has a threaded hole 11 on one side of the outlet short pipe 2. The conventional drain pipe has a connecting part fixed on it. When the conventional drain pipe is connected to the outlet short pipe 2, the screw is passed through the connecting part and threaded into the threaded hole 11. The condensate in the water storage chamber is discharged outdoors through the outlet short pipe 2 and the conventional drain pipe.
[0037] In this embodiment, the air conditioner's drain pipe is an easy-to-remove drain pipe. The indoor unit also includes a drain connector. When it is necessary to replace the traditional drain pipe with the easy-to-remove drain pipe, the traditional drain pipe is removed and the drain connector is installed, and then the easy-to-remove drain pipe is connected to the drain connector. With the addition of the drain connector and the easy-to-remove drain pipe, it is more convenient for users to repair, clean, or replace the drain pipe, which can improve the user experience. Moreover, compared with directly replacing the indoor unit, the economic cost is lower.
[0038] like Figures 1 to 4 As shown, specifically, the drain connector includes a connector body 31, a connecting assembly 32, a connector 33, and a sealing assembly 34. The connector body 31 includes a first connecting pipe 311 and a second connecting pipe 312. The inlet end of the second connecting pipe 312 extends into the outlet end of the first connecting pipe 311 and is fixedly connected to the inner circumferential wall of the first connecting pipe 311. Of course, the first connecting pipe 311 and the second connecting pipe 312 can also be integrally formed. The inlet end of the first connecting pipe 311 is inserted into the outlet short pipe 2 and connected to the indoor unit through the connecting assembly 32. The connecting assembly 32 includes a connecting flange 321 and a connecting screw 322. The connecting flange 321 is integrally formed at the inlet end of the first connecting pipe 311. The connecting screw 322 passes through the connecting flange 321 and is threaded into the threaded hole 11, thereby allowing the drain connector to be installed on the indoor unit.
[0039] like Figure 2As shown, in another preferred embodiment, the connecting assembly 32 includes a connecting plate 323 and a clamp 324. In this embodiment, the clamp 324 is an American-style hose clamp, but other types of hose clamps are also possible. The connecting plate 323 is integrally formed at the end of the first connecting pipe 311 and fits against the outer wall of the outlet short pipe 2. The connecting plate 323 has two through holes for the locking part of the clamp 324 to pass through. After the first connecting pipe 311 is inserted into the outlet short pipe 2, the user tightens the locking part of the clamp 324 to connect the connecting plate 323 to the outlet short pipe 2, thereby allowing the drain connector to be installed on the indoor unit.
[0040] like Figure 1 and Figure 3 As shown, the connector 33 includes a snap-fit, which is bonded or integrally formed onto the second connecting pipe 312. The detachable drain pipe includes a plug 41, a pipe body 43, a snap fastener 42, and at least one sealing ring 44. The sealing ring 44 is fixed to the inner wall of the plug 41 to seal the gap between the plug 41 and the second connecting pipe 312. The plug 41 is inserted into the water inlet end of the pipe body 43 and bonded to it. The snap fastener 42 is sleeved on the outside of the plug 41. The plug 41 is inserted into the water outlet end of the second connecting pipe 312, connecting the second connecting pipe 312 to the pipe body 43. At the same time, the snap fastener 42 is engaged with the snap-fit, enabling quick installation of the detachable pipe. When cleaning, repairing, or replacing the detachable drain pipe is required, pressing the snap fastener 42 disengages it from the snap-fit, allowing for quick removal of the detachable drain pipe, making it more convenient and easier to operate.
[0041] The structure of the indoor unit's frame 1 and the short outlet pipe 2 remains unchanged. The indoor unit can be connected to either a traditional drain pipe or an easily detachable drain pipe via a drain connector. Switching between the two is simple, allowing users to choose flexibly according to their needs. Furthermore, the drain connector has a low manufacturing cost, reducing costs for both manufacturers and users, thus achieving a balance between convenience and cost savings.
[0042] like Figure 1 and Figure 4As shown, the sealing assembly 34 is used to seal the gap between the outlet short pipe 2 and the connector body 31. The sealing assembly 34 includes an annular sealing gasket 341 and a limiting ring 342. The sealing gasket 341 is made of rubber or silicone, and the limiting ring 342 is made of a rigid material, preferably the same material as the second connecting pipe 312, such as rigid plastic. The sealing gasket 341 is bonded to the end of the second connecting pipe 312. The sealing gasket 341 has an annular sealing notch 3411. The outlet short pipe 2 fits against the inner wall of the first connecting pipe 311, and the end of the outlet short pipe 2 is inserted into the sealing notch 3411. The sealing notch 3411 increases the contact area between the sealing gasket 341 and the outlet short pipe 2, improving the sealing effect between the outlet short pipe 2 and the sealing gasket 341, thereby reducing the possibility of condensate leakage between the first connecting pipe 311 and the outlet short pipe 2.
[0043] The limiting ring 342 is fixed to the end of the second connecting pipe 312 and is located on the inner wall of the outlet short pipe 2 on the side facing away from the first connecting pipe 311. The limiting ring 342 has an adhesive surface 3421 on the side facing away from the outlet short pipe 2. The adhesive surface 3421 is inclined downwards in a direction away from the outlet short pipe 2. The sealing gasket 341 has a limiting groove 3412. The limiting ring 342 is inserted into the limiting groove 3412, and the sealing gasket 341 is adhered to the adhesive surface 3421. On the one hand, the limiting ring 342 supports the sealing gasket 341, reducing the possibility of bending and deformation of the sealing gasket 341, allowing the outlet short pipe 2 to be inserted more stably into the sealing groove, thereby improving the sealing performance between the first connecting pipe 311 and the outlet short pipe 2. On the other hand, the adhesive surface 3421 is inclined downward in the direction away from the water outlet short pipe 2, which can reduce the possibility of condensate flowing into the limiting groove 3412, so that the sealing gasket 341 can be more stably bonded to the second connecting pipe 312, which can further improve the sealing performance between the first connecting pipe 311 and the water outlet short pipe 2, and reduce the possibility of indoor water leakage.
[0044] like Figure 1 and Figure 4 As shown, the top wall of the sealing gasket 341 near the water flow side is set as an inclined surface 3413. The inclined surface 3413 is set inclined downward in the direction away from the water outlet short pipe 2. The inclined surface 3413 can reduce the obstruction effect of the sealing gasket 341 on the water flow, so that the condensate can be discharged more smoothly through the drain joint and the easy-to-disassemble drain pipe.
[0045] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
