The axis of the return pipe joint upper mounting hole 1.1 is vertically arranged with the water pan lower end surface 1.2. A plurality of locking bolt mounting holes 1.3 are provided around the return pipe joint upper mounting hole 1.1 on the lower end surface of the water pan 1. The locking bolt mounting holes 1.3 are internally threaded blind holes.

[0018] The return pipe joint assembly 2 comprises a return pipe joint upper section 2.1, a return pipe joint flange 2.2 and a return pipe joint lower section 2.3 which are coaxially fixed. The return pipe joint lower section 2.3 is used to connect the return pipe. The axes of the return pipe joint upper section 2.1 and the return pipe joint lower section 2.3 are perpendicular to the return pipe joint flange 2.2. The return pipe joint upper section 2.1 is a cylindrical tube. An annular radial sealing ring installation groove 2.11 is provided on the outer circle of the return pipe joint upper section 2.1. A locking bolt through hole 2.21 is provided on the return pipe joint flange 2.2. The locking bolt through hole 2.21 is a light hole. An annular end face sealing ring installation groove 2.22 is provided on the upper end face of the return pipe joint flange 2.2 and around the return pipe joint upper section 2.1.

[0019] The return pipe joint upper section 2.1 of the return pipe joint assembly 2 is inserted into the return pipe joint upper section mounting hole 1.1 of the water pan 1, and the outer circle of the return pipe joint upper section 2.1 is clearance-matched with the inner wall of the return pipe joint upper section mounting hole 1.1. The screw of the locking bolt 3 is installed in the locking bolt through hole 2.21 and the locking bolt mounting hole 1.3. The return pipe joint assembly 2 is fixed to the water pan 1 through the locking bolt 3. A radial sealing ring 4 is installed in the radial sealing ring mounting groove 2.11. The radial sealing ring 4 is used to seal the outer circle of the return pipe joint upper section 2.1 and the inner wall of the return pipe joint upper section mounting hole 1.1.

The upper end face of the return pipe joint flange 2.2 and the lower end face of the water pan 1 are sealed through the end face sealing ring 5.

[0020] The outer circle of the upper section 2.1 of the return pipe joint and the inner wall of the mounting hole 1.1 of the upper section of the return pipe joint are spaced 0.02-0.05 mm.

[0021] When the return pipe joint assembly 2 and the water tray 1 are in a separated state, the radial sealing ring 4 is 0.15-0.25 mm higher than the outer circle of the return pipe joint upper section 2.1.

[0022] When the return pipe joint assembly 2 and the water pan 1 are in a separated state, the end face sealing ring 5 is 0.15-0.25 mm higher than the upper end face of the return pipe joint flange 2.2.

[0023] In the utility model, the return pipe joint assembly 2 is a processed part, and an annular radial sealing ring installation groove 2.11 is provided on the outer circle of the return pipe joint upper section 2.1, and the radial sealing ring installation groove 2.11 is used to install the radial sealing ring 4, and an annular end face sealing ring installation groove 2.22 is provided on the upper end face of the return pipe joint flange 2.2 and around the return pipe joint upper section 2.1, and the end face sealing ring installation groove 2.22 is used to install the end face sealing ring 5.

[0024] The upper mounting hole 1.1 of the return pipe joint is opened on the water pan 1, and the lower end face 1.2 of the water pan is processed, ensuring that the axis of the upper mounting hole 1.1 of the return pipe joint is perpendicular to the lower end face 1.2 of the water pan. The radial sealing ring 4 is inserted into the radial sealing ring mounting groove 2.11, and the end face sealing ring 5 is inserted into the end face sealing ring mounting groove 2.22. The radial sealing ring 4 is 0.15~0.25mm higher than the outer circle of the upper section 2.1 of the return pipe joint, and the end face sealing ring 5 is 0.15~0.25mm higher than the upper end face of the return pipe joint flange 2.2. The double sealing ensures that there will be no leakage.

[0025] The outer circle of the return pipe joint upper section 2.1 and the inner wall of the return pipe joint upper section mounting hole 1.1 are spaced 0.02~0.05mm, and the reserved gap ensures that the return pipe joint upper section 2.1 on the return pipe joint assembly 2 can be smoothly installed into the return pipe joint upper section mounting hole 1.1, and does not affect the sealing performance. During installation, it is only necessary to put the return pipe joint assembly 2 with the radial sealing ring 4 and the end face sealing ring 5 installed into the return pipe joint upper section mounting hole 1.1, and then lock the locking bolt 3 in the locking bolt mounting hole 1.3 and the locking bolt through hole 2.21.

[0026] When disassembling, it is only necessary to unscrew the locking bolt 3 and pull out the return pipe joint assembly 2 downwards, so that the return pipe joint assembly 2 can be separated from the water pan 1.

[0027] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
