DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] A separate drum washing machine, such as Figures 1 to 6As shown, it includes a shell 1, a water pipe 2, a rotating shaft 3 and a conductive slip ring 4. A driving component 5 is arranged in the shell 1. The driving component 5 is used to drive the rotating shaft 3 to rotate. In this embodiment, the driving component 5 includes a rotating driving source 51, a transmission wheel 52, a transmission belt 53 and a coupling 54. The output end of the rotating driving source 51 is connected to the transmission wheel 52, the transmission wheel 52 and the coupling 54 are connected to the rotating shaft 3 through the transmission belt 53. The coupling 54 is connected to the rotating shaft 3. The output end of the rotating driving source 51 drives the transmission wheel 52 to rotate, the transmission wheel 52 drives the coupling 54 to rotate through the transmission belt 53, and the coupling 54 drives the rotating shaft 3 to rotate. The rotating driving source 51 is preferably a servo motor, and other driving sources with a rotation function can also be used. In other embodiments, the rotating driving source 51 can also use a DDM brushless DC motor, the stator of the DDM brushless DC motor is connected to the support seat 8, and the rotor of the DDM brushless DC motor is connected to the rotating shaft 3.

[0027] An inner barrel 6 for storing water is rotatably arranged in the outer shell 1, a water collecting ring 7 is connected to the inner barrel 6, and a rotating shaft 3 is connected to the inner barrel 6, so when the rotating shaft 3 rotates, the inner barrel 6 can be driven to rotate, and the water collecting ring 7 is driven by the inner barrel 6 to rotate.

[0028] A support seat 8 is provided in the outer shell 1, and a bearing 23 is provided between the rotating shaft 3 and the support seat 8. Preferably, there are two bearings 23 and the two are distributed at an interval. The bearing 23 can effectively improve the stability of the rotating shaft 3 during rotation, thereby improving the stability of the inner barrel 6 and the water collecting ring 7 during rotation.

[0029] The conductive slip ring 4 is coaxially arranged with the rotating shaft 3, and a cover shell 16 is arranged on the rotating shaft 3. In this embodiment, the rotating shaft 3 and the cover shell 16 are integrally arranged, and a accommodating cavity 17 is arranged in the cover shell 16. The conductive slip ring 4 is arranged in the accommodating cavity 17. A water seal 18 is arranged between the support seat 8 and the rotating shaft 3, and the water seal 18 is sleeved on the outside of the cover shell 16. The water seal 18 seals the accommodating cavity 17 to prevent water from entering the accommodating cavity 17 and affecting the normal operation of the conductive slip ring 4.

[0030] The water pipe 2 extends into the inner barrel 6, and the water pipe 2 connects the external water supply unit and the inner barrel 6. The water from the external water supply unit enters the inner barrel 6 through the water pipe 2. The water pipe 2 is a hard pipe. It should be noted that since the inner barrel 6 is sealed, the internal air pressure of the inner barrel 6 is inconsistent with the external air pressure, and the water flow cannot actively enter the inner barrel 6. Therefore, a pipe 14 is arranged in the water pipe 2, one end of the pipe 14 extends into the inner barrel 6, and the other end of the pipe 14 extends out of the outer shell 1. The pipe 14 is a soft pipe, and the external gas can enter and exit the inner barrel 6 through the pipe 14, thereby balancing the air pressure, thereby ensuring that the water flow can enter the inner barrel 6 through the water pipe 2. The water pipe 2 is connected to the support seat 8, thereby ensuring the stability of the water pipe 2.

[0031] A water collecting ring 7 is rotatably arranged in the outer shell 1, and the water collecting ring 7 can be connected with the inner barrel 6. Specifically, the inner barrel 6 is connected with the water collecting ring 7 through a first channel 9, and a control valve 10 for controlling the on-off is arranged in the first channel 9. The water collecting ring 7 can be connected with the outside. Specifically, a drainage channel 11 connected with the outside is arranged on the water collecting ring 7, and a control valve 2 12 for controlling the on-off is arranged in the drainage channel 11. A drainage pipe 13 is arranged on the support seat 8. When the water collecting ring 7 rotates to align the drainage channel 11 with the drainage pipe 13, the drainage channel 11 can be connected with or separated from the drainage pipe 2.

[0032] Specifically, a clutch rod 25 is rotatably provided on the support seat 8, and the end of the clutch rod 25 is connected to the drain pipe 2. A reset spring 27 is sleeved on the drain pipe 13. The clutch rod 25 rotates to drive the drain pipe 13, so that the drain pipe 13 and the drain channel 11 are connected, that is, the drain pipe 13 is connected with the drain channel 11, and under the elastic force of the reset spring 27, the drain pipe 13 is reset, and at this time the drain channel 11 is separated from the drain pipe 13.

[0033] During normal washing operation, control valve 1 10 and control valve 2 12 are closed, the first channel 9 is in a disconnected state, the clothes and water are stored in the inner barrel 6, and the shaft 3 is driven to rotate by the driving assembly 5, and the shaft 3 drives the inner barrel 6 to rotate, thereby performing washing work.

[0034] During dehydration, control valve 10 is opened and control valve 2 12 is closed, the first channel 9 is in a connected state, the inner barrel 6 is connected to the water collecting ring 7 through the first channel 9, and the water in the inner barrel 6 enters the water collecting ring 7 through the first channel 9. Since the clothes are washed in the inner barrel 6, the impurities precipitated after washing will enter the water collecting ring 7 along with the water, thereby effectively ensuring the cleanliness of the inner barrel 6, preventing impurity residues from causing pollution to the inner barrel 6, and avoiding impurity residues from affecting the cleanliness of the clothes.

[0035] It should be further explained that, in order to make it easier for the water in the inner tub 6 to enter the first channel 9, a diversion slope may be provided in the inner tub 6 or the inner tub 6 may be tilted.

[0036] When draining water, the servo motor is calibrated so that after the water collecting ring 7 rotates, the drainage channel 11 is aligned with the drainage channel 13, and the clutch rod 25 rotates to move the drainage pipe 13, so that the drainage pipe 13 and the drainage channel 11 are sealed and connected, that is, the drainage pipe 13 is connected with the drainage channel 11, and then the control valve 2 12 is opened, and the water in the water collecting ring 7 flows through the drainage channel 11 into the drainage pipe 2, and finally flows out to achieve drainage.

[0037] It should be noted that the drainage action can be performed a corresponding number of times according to the moisture content of the clothes, but before each drainage, it is necessary to ensure that the inner drum is reset to the initial position.

[0038] Since leakage is prone to occur when the drainage channel 11 is connected to the drainage pipe 13, a leakage channel 15 connected to the outside is provided on the support seat 8, and the water in the support seat 8 can be discharged from the leakage channel 15. As another solution, the drainage pipe 13 can also be coaxially arranged in the leakage channel 15.

[0039] A main shaft cover 19 is provided at the barrel mouth of the inner barrel 6, a fixed cover 20 is provided on the main shaft cover 19, a cover door 21 is provided on the fixed cover 20, and the cover door 21 is installed on the side cover 28. A water seal 22 is provided between the main shaft cover 19 and the inner barrel 6. Preferably, the water seal 22 can be fixed to the inner barrel 6 by locking with a steel wire. The main shaft cover 19 and the inner barrel 6 are sealed by the water seal 22 to avoid leakage. When the inner barrel 6 rotates, the main shaft cover 19 and the inner barrel 6 rotate simultaneously, and a bearing 24 is provided between the main shaft cover 19 and the fixed cover 20.

[0040] The main shaft cover 19, the fixed cover 20, and the inner ring of the second bearing 24 rotate together with the inner barrel 6. The water seal 22 is installed on the inner barrel 6. The cover door 21 presses the fixed cover 20. The cover door 21 is connected to the fixed cover 20 by screws. The cover door 21 is installed on the side cover 28. The side cover 28 is connected to the support seat 8 through the connecting column 26, so as to improve the stability of the main shaft cover 19 during rotation, and further improve the stability of the inner barrel 6 and other rotating components during rotation.

[0041] As another solution, the connection between the cover door 21 and the fixed cover 20 can be connected by a plurality of U-shaped elastic sheets 29, one end of the U-shaped elastic sheet 29 is fixed to the cover door 21, and the other end of the U-shaped elastic sheet 29 is fixed to the fixed cover 20. The U-shaped elastic sheet 29 can effectively reduce the vibration caused by the radial eccentricity of the inner barrel 6, thereby improving the stability of the inner barrel 6 and other rotating components during rotation.

[0042] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field to which the utility model belongs can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
