[0038] As can be seen from the above, the washing machine of the present invention is provided with a heat pump dehumidification device 2, which is used to dry the hot and humid air discharged from the washing liner 1, and then the high-temperature dry gas after drying flows back to the washing liner 1 and continues to be used for the drying operation inside the washing liner 1. Compared with the method of directly introducing cold air with a certain amount of moisture in the prior art, the introduction of high-temperature dry gas in the present invention can improve the drying efficiency inside the washing liner 1.

[0039] The heat pump dehumidification device 2 in the present invention adopts an existing structure, such as the structure disclosed in the prior art such as the Chinese utility model patent with patent number ZL202120329428.6 (authorization announcement number CN215446689U) and the Chinese utility model patent with patent number ZL202120329428.6 (authorization announcement number CN215446689U).

[0040] Furthermore, it also includes an adjustment mechanism 3 for changing the air intake direction at the reflux port 12. In this way, the refluxed high-temperature drying can be directed to the desired place, for example, the bottom of the cups and bowls placed in the upper bowl rack, the inside of the tableware placed in the opening, or the washing water remaining in the concave part, etc., to solve the problems of incomplete drying of tableware, moisture at the bottom of the washing liner 1, or moisture at the tableware on the lower bowl rack, and improve the drying effect.

[0041] Furthermore, the first air outlet 22 is connected to the return port 12 through the return pipe 4, and the regulating mechanism 3 includes an regulating sleeve 31 installed in the return pipe 4 along the length direction of the return pipe 4, the first end of the regulating sleeve 31 extends into the cleaning inner tank 1, and the second end can rotate relative to the inner surface of the return pipe 4 where it is located to adjust the angle of the first end of the regulating sleeve 31 relative to the return port 12. In this way, the angle of the first end of the regulating sleeve 31 is adjusted by setting the regulating sleeve 31 and rotating the regulating sleeve 31, thereby achieving the adjustment of the air intake direction of the return port 12.

[0042] Furthermore, the outer surface of the second end of the adjusting sleeve 31 is spherical and can rotate relative to the inner surface of the return pipe 4 where the second end is located, with its own spherical center as the center, so that the adjusting sleeve 31 can better rotate relative to the return pipe 4, and then better adjust the air intake direction of the return port 12. Furthermore, the spherical center of the second end of the adjusting sleeve 31 is on the straight line where the central axis of the return port 12 is located, and the first end of the adjusting sleeve 31 can swing back and forth up and down with the straight line where the central axis of the return port 12 is located as the center. In this embodiment, the angle adjustment range of the first end of the adjusting sleeve 31 relative to the straight line where the central axis of the return port 12 is located is: 0~12°. In addition, the adjustment mechanism 3 further includes a circular rotating disk 33, a first motor 32 for driving the rotating disk 33 to rotate, and a linkage rod 34, one end of the linkage rod 34 is connected to a first rotating shaft 341 fixed on the disk surface of the rotating disk 33, and the other end is connected to a second rotating shaft 342 fixed on the adjusting sleeve 31, wherein the first rotating shaft 341 is perpendicular to the disk surface of the rotating disk 33 where it is located, and is fixed at the periphery of the disk surface, and the second rotating shaft 342 is parallel to the first rotating shaft 341. In this way, the first motor 32 drives the rotating disk 33, and the rotation of the rotating disk 33 drives the linkage rod 34, thereby driving the adjusting sleeve 31 through the linkage rod 34.

[0043] Furthermore, the second end of the adjusting sleeve 31 is always embedded in the reflux pipe 4, and the first end can be extended relative to the second end along the length direction of the adjusting sleeve 31. In this way, the blowing range of the gas returning from the reflux port 12 can be changed by extending and retracting the first end of the adjusting sleeve 31, and the high-temperature dry air returning can be better guided to the desired place by cooperating with the rotation of the adjusting sleeve 31. Preferably, the first end of the adjusting sleeve 31 is extended and retracted relative to the second end thereof under the drive of the linkage rod 34. In this way, the angle and length of the adjusting sleeve 31 can be adjusted synchronously.

[0044] The specific structure of the adjusting sleeve 31 can be various. In this embodiment, preferably, the adjusting sleeve 31 includes an outer tube 311 and a retractable corrugated inner tube 312 embedded in the outer tube 311, and the second rotating shaft 342 is fixed on the corrugated inner tube 312. Figure 3 to Figure 6 Specifically, the first end of the corrugated inner tube 312 is fixed to the inner surface of the outer tube 311 along the circumferential direction, while the second end is freely arranged and can be telescopically moved back and forth along the length direction of the adjusting sleeve 31 under the drive of the linkage rod 34, thereby adjusting the length of the adjusting sleeve 31. Further, in this embodiment, the return pipe 4 where the adjusting sleeve 31 is located extends horizontally, as shown in FIG. Figure 3 As shown, in the initial state, the adjusting sleeve 31 extends horizontally, the air intake direction at the reflux port 12 is horizontal, and the linkage rod 34 extends horizontally and presses the corrugated inner tube 312 into the outer tube 311 to make the length of the adjusting sleeve 31 the shortest. When the first motor 32 is in working state, the rotation of the turntable 33 drives the linkage rod 34 to rotate synchronously, so that the adjusting sleeve 31 rotates with the ball center of the second end thereof as the center, and the corrugated inner tube 312 moves relative to the outer tube 311 to change the length of the adjusting sleeve 31, thereby changing the air intake direction at the reflux port (such as Figure 4 , Figure 5 as well as Figure 6 shown).

[0045] Furthermore, the cleaning machine in the present invention also includes a water tank 8, the bottom wall of which is provided with a drain port 81 and a drain device 5 for opening and closing the drain port 81, and the heat pump dehumidification device 2 also has a second air outlet 23 for discharging humid air, and the second air outlet 23 is fluidically connected to the drain port 81. In the present invention, the humid air is discharged into the water tank 8, which can avoid the noise caused by discharging the gas directly into the drain pipe 82 on the one hand, and the humid air can infiltrate the dirt on the bottom surface of the water tank 8 on the other hand, so as to facilitate the subsequent cleaning of the water tank 8. In the present embodiment, the drain pipe 82 is provided with a guide port 821, and the guide port 821 is connected to the second air outlet 23 through a guide joint 822, so as to realize the connection between the second air outlet 23 and the drain port 81, as shown in FIG.

In the initial state, the water discharger 5 is embedded in the water outlet 81 to close the water outlet 81, and the elastic member 7 is in a compressed state; the pressing member 6 is pressed downward to make the pressing member 6 move downward, and the elastic member 7 is compressed to make the pressing member 6 have a tendency to move upward and reset. When the pressing force applied to the pressing member 6 is cancelled, the elastic member 7 releases potential energy to make the pressing member 6 move upward, until the pressing member 6 moves upward to the position and is limited, and the elastic member 7 continues to release potential energy, and the water discharger 5 is separated from the water outlet 81 and the water outlet 81 is opened. When the drain outlet 81 is in the closed state, a water film is formed between the edge of the drain outlet 81 and the drain 5, so that the drain 5 is firmly embedded in the drain outlet 81. Therefore, it is difficult to pull out the drain 5 from the drain outlet 81. The present invention facilitates users to open the drain outlet 81 through the above-mentioned arrangement.

Figure 2 In the initial state, the stop block 61 abuts against the bottom surface of the drain 5, and the elastic member 7 is sandwiched between the stop block 61 and the bottom wall of the cover 83. By providing the stop block 61, on the one hand, the upper limit of the pressing member 6 can be achieved, and on the other hand, the elastic member 7 can be stably installed and the elastic member 7 can smoothly accumulate potential energy during the downward movement of the pressing member 6.

Thus, it is possible to provide an air source for the gas circulation inside the cleaning liner 1 and between the cleaning liner 1 and the heat pump dehumidification device 2, and by providing the regulating mechanism 3 to change the air inlet direction of the air inlet 13, the incoming air can be directed to the desired place, which is conducive to improving the drying efficiency and the drying effect.
