The invention provides an indoor unit of an air conditioner.
Referring to fig. 1 to 12, in an embodiment of the present invention, the indoor unit of an air conditioner is specifically a wall-mounted indoor unit of an air conditioner, and the indoor unit of an air conditioner includes a spiral casing 1, a front water pan 11 and a drainage assembly, the front water pan 11 is disposed at a front side of an upper portion of the spiral casing 1, water outlets 12 are disposed at left and right ends of the front water pan 11, and the drainage assembly includes a drainage pipe 2 and a joint structure 3. Wherein, the joint structure 3 includes a joint pipe 31 and a ring sleeve 32; one end of the joint pipe 31 is butted with the water outlet throat 12, the other end is communicated with the drain pipe 2, and the joint pipe 31 is provided with a clamping part 311 clamped with the water outlet throat 12; the ring sleeve 32 is arranged on the outer peripheral surface of the joint pipe 31 and has a first position and a second position; when the ring sleeve 32 is located at the first position, the clamping part 311 is clamped with the water outlet throat 12; when the ring sleeve 32 is located at the second position, the clamping part 311 is separated from the water outlet throat 12.
It should be noted that, referring to fig. 6, 8 and 9, in the present embodiment, as to the connection manner of the joint pipe 31 and the drain pipe 2, specifically, the end surface of the pipe orifice of the joint pipe 31 away from the front water pan 11 is provided with an annular connection groove 312, the drain pipe 2 has a water inlet end close to the water outlet throat 12, and the end surface of the water inlet end is correspondingly convexly provided with an annular insertion portion 21 capable of being tightly inserted into the connection groove 312, so that the drain pipe 2 can be inserted and fixed into the connection groove 312. Here, the joint pipe 31 and the water discharge pipe 2 may be detachably connected to facilitate the disassembly and assembly of the water discharge pipe 2, or may be fixedly connected or even integrally formed, for example, but not limited to, the pipe wall of the insertion portion 21 of the water discharge pipe 2 is fixed to the groove wall of the connection groove 312 by hot melt adhesive or glue. Referring to fig. 2, in the present embodiment, the joint structure 3 further includes a thermal insulation cover 33 fitted over the outer peripheral surface of the joint structure 3. It can be understood that since the condensed water is usually at a low temperature, the junction between the water outlet throat 12 and the water outlet pipe 2, i.e. the joint pipe 31 and the ring sleeve 32, will also be at a low temperature, and the heat-insulating sleeve 33 can have a certain heat-insulating effect on the two components, so as to prevent the generation of condensation.
In this embodiment, the process of attaching and detaching the water outlet throat 12 and the water discharge pipe 2 through the joint structure 3 is as follows: when the water outlet throat 12 needs to be connected with the water discharge pipe 2, firstly, two ends of the joint pipe 31 are respectively connected with the free end of the water outlet throat 12 and the water inlet end of the water discharge pipe 2, at the moment, the ring sleeve 32 is located at the second position, then, the ring sleeve 32 is moved from the second position to the first position, and at the first position, the ring sleeve 32 presses the clamping part 311, so that the clamping part 311 is elastically deformed to be clamped with the water outlet throat 12, and the fixed connection between the water outlet throat 12 and the water discharge pipe 2 is realized and is not easy to loosen; when the water outlet pipe 2 needs to be detached from the water outlet throat 12, the ring sleeve 32 can be moved from the first position to the second position, at the moment, the abutting pressure of the ring sleeve 32 on the clamping portion 311 disappears, and the clamping portion 311 can rebound and be separated from the water outlet throat 12, so that the joint pipe 31 can be separated from the water outlet throat 12 relatively. As can be seen from the above dismounting process, the dismounting of the drain pipe 2 and the water outlet 12 only needs to correspondingly move the ring sleeve 32 on the joint pipe 31, the dismounting process is very convenient, and the dismounting convenience of the drain pipe 2 and the water outlet 12 can be greatly improved.
Specifically, referring to fig. 4 to 12, in the present embodiment, the water outlet throat 12 is provided with an annular locking groove 121, and the locking portion 311 includes an elastic arm 311a and a locking protrusion 311b provided at a free end of the elastic arm 311a and corresponding to the locking groove 121; when the ring sleeve 32 is located at the first position on the joint pipe 31 close to one side of the front water collecting tray 11, the free end of the water outlet throat 12 is embedded in the joint pipe 31, and at this time, the ring sleeve 32 presses against the free end of the elastic arm 311a, so that the elastic arm 311a elastically deforms towards the clamping groove 121, and the clamping protrusion 311b is clamped into the clamping groove 121. However, the design is not limited thereto, and in other embodiments, the locking groove 121 may not be disposed annularly, for example, the locking groove 121 may be a groove for only the locking protrusion 311b to be locked in, and in addition, the locking protrusion 311b may also be disposed at the water outlet throat 12, and correspondingly, the locking groove 121 is disposed at the free end of the elastic arm 311 a. Further, as shown in fig. 9, the joint pipe 31 is provided with a clearance hole 311c for providing a space for the elastic deformation of the elastic arm 311a, the elastic arm 311a is formed to extend from the hole edge of the clearance hole 311c in a direction approaching the front drain pan 11, and a gap is formed between the elastic arm 311a and the peripheral wall surface of the clearance hole 311c, which can reduce the interference between the elastic arm 311a and the clearance hole 311c when the elastic arm 311a is elastically deformed. Of course, in other embodiments, the joint pipe 31 may be provided with only the locking hole for the locking protrusion 311b to pass through, and the elastic arm 311a may also be formed to extend along the circumferential direction of the joint pipe 31. In addition, to further enhance the clamping action of the elastic arms 311a, the elastic arms 311a may be provided in a plurality, and are preferably evenly spaced along the circumferential direction of the joint pipe 31, for example, in the present embodiment, two elastic arms 311a are provided and are symmetrically distributed on the joint pipe 31.
