When draining, it is necessary to open the water sealing plate on the bottom of the washing tub. The opening of the disc is controlled by the drainage shaft connected to it. Since the input part controls the drainage shaft and the pulsator shaft connected to the pulsator to control the rotation together, the required torque is relatively large, and the pulsator shaft is subject to great resistance from the pulsator. , and the power to control the drainage shaft and the pulsator shaft is the direct power transmission of the input end, and the power cannot be amplified by the reduction gear train, thus causing no drainage. It is necessary to take out the clothes in advance, which is not only troublesome and labor-intensive, but also cannot realize automatic control. This is a technical problem that we urgently need to solve at present.

Detailed ways

Combined with Fig. 1 and Fig. 2, it is a schematic structural diagram of an embodiment of the water-saving washing machine deceleration clutch of the present invention, which includes a pulsator shaft 6 connected to the pulsator of the washing machine, placed outside the pulsator shaft 6 and connected to the flange 8 of the washing machine's water-saving washing tub The connected dehydration shaft 4 is placed between the pulsator shaft 6 and the dehydration shaft 4, and the drainage shaft 5 is connected to the drain pan 7 for drainage. The wheel train is connected with the input shaft 1, the upper part of the brake wheel 3 is fixed with the dehydration shaft 4, the lower part of the brake wheel 3 is fixed with the clutch shaft 2, and the clutch shaft 2 rotates and is placed on the input shaft 1. Outside, an intermediate shaft 14 is provided between the clutch shaft 2 and the input shaft 1, and the reduction gear train includes an input shaft gear arranged at the top of the input shaft 1, and an upper ring gear 11 placed around the input shaft gear. , the upper planetary gear placed between the input shaft gear and the upper ring gear 11 and the inner side meshing with the input shaft gear and the outer side meshing with the upper ring gear 11, the upper planetary gear is rotatably installed on the upper planet carrier 10, The upper inner ring gear 11 is connected with the clutch shaft 2 through the lower planet carrier 13. The lower planet carrier 13 is provided with a movable lower planetary gear. It meshes with the lower inner ring gear 12, and the lower inner ring gear 12 is connected with the drainage shaft 5; the intermediate shaft 14, the input shaft 1 and the clutch shaft 2 are provided with bearings for supporting lubricating rotation; The drainage shaft 5, the impeller shaft 6, and the dehydration shaft 4 are provided with bearings for supporting and lubricating rotation; the clutch shaft 2, the dehydration shaft 4 and/or the brake wheel 3 are connected to the shell through the bearing and the sealing ring. The body 9 is movably connected; the intermediate shaft 14, the clutch shaft 2, and the input shaft 1 are provided with a clutch sleeve 15 for controlling the mutual conversion of washing, draining and dehydrating working conditions.

The clutch sleeve 15 is composed of an inner part and an outer part. The two parts can be radially rotatable and connected as a whole. The inner part is axially slidably mounted on the intermediate shaft 14, and the outer part is axially slidably mounted. On clutch shaft 2.

The clutch sleeve 15 has three positions: upper, middle, lower, and the initial position is in the upper gear position (as shown in the figure). At this time, the outer part of the clutch sleeve 15 is engaged with the housing 9 and remains motionless, that is, The clutch shaft 2 remains motionless, and the inner part of the clutch sleeve 15 connected with the intermediate shaft also remains motionless under the action of external force, and the input shaft 1 is separated from the clutch sleeve 15, which is the clutch sleeve 15 in the washing condition. connection status.

When the clutch sleeve 15 moves downwards to the middle position under the action of external force, the outer part of the clutch sleeve 15 is still in engagement with the housing 9 and remains stationary, but its inner part moves down with the housing 9. The input shaft 1 is combined, because the inner and outer parts of the clutch sleeve can rotate relative to each other, under the action of the computer board program, the input shaft 1 and the intermediate shaft 14 rotate at an angle at the same time, and drive the drainage shaft under the action of the gear train 5 Rotate an angle, at this time, the drain pan 7 and the flange 8 rotate an angle relative to each other to fully open the drain holes, and this is the connection state of the clutch sleeve during the drainage working condition.

When the clutch sleeve 15 is subjected to external force and then slides down to the lower position, its inner part is fully engaged with the input shaft 1, and its outer part is separated from the housing 9, and the clutch shaft 2, the intermediate shaft 14 and the input shaft 1 are connected as As a whole, this is the connected state when dehydrated. When the dehydration is finished, the clutch sleeve 15 returns to the neutral position under the action of the external force, the outer part of the clutch sleeve 15 engages with the housing 9 and remains stationary, but its inner part is still combined with the input shaft 1, Since the inner and outer parts of the clutch sleeve can rotate relative to each other, under the action of the computer board program, the input shaft 1 and the intermediate shaft 14 rotate in the opposite direction at the same time, and the drainage shaft 5 is driven to rotate by one angle under the action of the wheel train. At this time, the drain pan 7 and the flange 8 are rotated at an angle relative to each other to completely close the drain holes. This is the connection state when the drain holes are closed.

When the clutch sleeve 15 returns to its initial position under the action of an external force, the outer part of the clutch sleeve 15 is completely engaged with the housing 9 and remains stationary, and its inner part is completely disengaged from the input shaft 1, returning to washing The connection status in working condition.

In washing mode: under the action of the clutch sleeve 15, the intermediate shaft 14 and the clutch shaft 2 remain stationary, the input shaft 1 drives the upper planetary carrier 10 to rotate, and the pulsator shaft 6 connected to the upper planetary carrier 10 achieves decelerated rotation to wash clothes ;

Drainage working condition: Under the action of the clutch sleeve 15, the clutch shaft 2 remains stationary, and the intermediate shaft 14 is connected with the input shaft 1 as a whole. When the input shaft 1 obtains a short-term power rotation, it drives the upper planetary carrier 10 Rotation and lower ring gear 12 reverse rotation, under the action of the reduction gear train, the drainage shaft 5 obtains a decelerated and increased torque, which drives the drainage pan 7 to rotate, and the drainage holes on the drainage pan 7 and the drainage holes on the flange 8 Conduction, open the drain valve to drain water;

In the dehydration working condition: under the action of the clutch sleeve 15, the clutch shaft 2, the intermediate shaft 14 and the input shaft 1 are connected as a whole. When the input shaft 1 obtains a long-term power rotation, it drives the upper planet carrier 10 to rotate, and the lower The inner ring gear 12 and the brake wheel 3 rotate together, so that the dehydration shaft 4, the drainage shaft 5 and the pulsator shaft rotate at high speed together for dehydration;

On the contrary, after dehydration, the lower ring gear 12 rotates an angle in the opposite direction when draining, and closes the drain pan 7, and the drain holes on the drain pan 7 and the drain holes on the flange 8 are closed.
