[0043] Water flows from the water inlet pipe 5 to the water outlet pipe 6, and impurities in the water are filtered inside the circular pipe 201 because the filter part 202 is arranged at one end of the circular pipe 201 facing the water outlet pipe 6. When the filter 2 needs to be cleaned, the filter 2 is taken out from the installation opening 101, and the filtered impurities are also in the circular pipe 201. When the circular pipe 201 is taken out, the impurities are also taken out from the pipeline. Only the circular pipe 201 needs to be cleaned, which is very convenient and does not need to be handled by professional personnel.

[0044] Preferably, as shown in Figures 1-3 The adapter pipe 7 is screwed with the water outlet pipe 6.

[0045] By screwing the adapter pipe 7 with the water outlet pipe 6, the efficiency of installation and dismounting is improved.

[0046] Preferably, as shown in Figures 1-3 The cross section of the filter section is circular, and the installation port 101 is rectangular; the installation port 101 comprises a first side and a second side which are parallel to the axis of the filter section; on the cross section which passes through the first side and is perpendicular to the filter section, the length of the solid part between the first side and the second side is greater than half of the circumference of the circular.

[0047] By the above setting, in the circumferential direction of the filter section, the length of the solid structure taken out for setting the installation port 101 is less than the reserved length, and when the filter element 2 is set in the filter section, the solid part of the filter section corresponding to the installation port 101 in the axial direction can wrap the filter element 2, so that the filter element 2 can be more firmly fixed in the filter section, and the filter efficiency is not reduced due to the insecure fixing of the filter element 2.

[0048] Further, when the filter element 2 comprises a circular pipe 201, the part of the outer circumferential surface of the circular pipe 201 which closely contacts the inner wall surface of the filter section surrounds a circumference of the circular pipe 201, specifically, a circumference of one end of the circular pipe 201, so that the water leakage from the gap between the circular pipe 201 and the filter section is avoided. The filter section has a certain elasticity and can tightly wrap the circular pipe 201.

[0049] The utility model also provides a kind of air conditioner, including indoor unit and the drain device of the described, the drain pipe of indoor unit includes the water inlet pipe 5 and water outlet pipe 6, the inner wall of the water inlet pipe 5 is smooth surface, the water outlet pipe 6 is bellows, the inlet of the water inlet pipe 5 is communicated with the indoor unit, the outlet of the water outlet pipe 6 leads to outdoor, the filter assembly is located the outside of indoor unit.

[0050] The filter assembly is arranged outside the indoor unit, which facilitates the dismounting and installation of the filter element 2.

[0051] The inner wall of the water inlet pipe 5 is smooth surface, which reduces the impurities remaining in the water inlet pipe 5, and the water outlet pipe 6 is bellows, which facilitates the bending of the water outlet pipe 6 to discharge water from the indoor,

[0052] The utility model provides a kind of assembly method for the above-mentioned drain device, and the assembly method comprises: mounting or dismounting filter element 2 from the installation port 101 on the filter section.

[0053] Installing and removing the filter element 2 via the installation port 101 is very convenient, requiring no disassembly of the air conditioner casing or the use of professional personnel, and allows for timely cleaning of impurities filtered in the drainage device.

[0054] Preferably, the filter element 2 is installed through the mounting port 101 on the filter section, including:

[0055] Step 1: Control the connecting pipe 1 to be in the first working position;

[0056] Step 2: Insert the second end of the control tube 201 into the mounting port 101 and insert it to a preset depth towards the outlet section.

[0057] Step 3: Control the connecting pipe 1 to be in the second working position.

[0058] Specifically, the inlet and outlet sections are bent in the first direction, causing the corresponding filter section to bend, while the mounting port 101 protrudes in the second direction; since the angle formed by the intersection of the axis of the inlet section and the axis of the outlet section is 170°≥α≥90°, that is, as... Figure 5 As shown, the connecting pipe 1 is shaped like a large "V," which facilitates the insertion of the second end of the circular pipe 201 into the filter pipe through the mounting hole, reaching a predetermined depth towards the outlet section. After the circular pipe 201 is inserted to the predetermined depth, the connecting pipe 1 is in the second working position. At this time, the angle between the axis of the inlet section and the axis of the outlet section is 180°≥β≥175°, meaning that the axis of the connecting pipe 1 is essentially a straight line, and the connecting pipe 1 is essentially a straight pipe. The filter device is in the working position.

[0059] Preferably, the assembly method further includes: before installation, connecting pipe 1 and connecting pipe 7 are threaded together, and the threaded connection length is controlled to be L1.

[0060] First, connect the connecting pipe 1 and the connecting pipe 7 by thread to facilitate control of the bending of the connecting pipe 1. The threaded connection length is L1, which ensures the stability of the connection between the connecting pipe 1 and the connecting pipe 7.

[0061] Preferably, the circular tube 201 is a rigid structure, and the outer diameter of the second end of the circular tube 201 can transitionally fit with the inner diameter of the outlet section. The assembly method also includes a method for fixing the filter element 2, which includes:

[0062] Step 1: Control the rotation of the round tube 201 to make the round tube 201 threadedly connected to the connecting tube 7;

[0063] Step 2: Control the rotation of connecting pipe 1 so that the threaded connection length between connecting pipe 1 and connecting pipe 7 is L2, where L2 > L1.

[0064] Step one, control the rotation of the round pipe 201 to make the round pipe 201 and the adapter pipe 7 threadedly connected, and make the first end of the round pipe 201 and the adapter pipe 7 fixedly connected together.

[0065] Step two, control the rotation of the connecting pipe 1 to make the connecting pipe 1 and the adapter pipe 7 threadedly connected with the length of L2, L2>L1, that is, the connecting length of the connecting pipe 1 and the adapter pipe 7 is lengthened, and the connecting pipe 1 as a whole moves towards the direction of the water inlet pipe 5, which makes the second end of the round pipe 201 relatively fixed to the adapter pipe 7 inserted into the outlet section of the connecting pipe 1 and interference fit with the outlet section, since the outlet section is a rigid structure and the round pipe 201 is also a rigid structure, the first end of the round pipe 201 is relatively fixedly connected to the inlet end of the connecting pipe 1 through the adapter pipe 7, and the second end of the round pipe 201 is interference fit with the outlet section, which makes the connecting pipe 1 not bent due to the flexible structure of the filtering section, and ensures the smoothness of water flow and the sealing between the round pipe 201 and the connecting pipe 1.

[0066] Further, a sealing ring can be arranged on the outer periphery of the second end of the round pipe 201, and the gap between the round pipe 201 and the outlet section is sealed when the second end of the round pipe 201 is inserted into the outlet section.
