Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

An pulsator washing machine 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 24.

As shown in fig. 1 to 24, the pulsator washing machine 100 according to an embodiment of the present invention includes: a hole-free inner barrel 1, a sealing disc 2 and a driving device 3.

Specifically, as shown in fig. 1 to 5, the bottom 11 of the non-porous inner tub 1 is provided with a drain hole 111; the water in the non-porous inner tub 1 can be discharged from the drain hole 111 of the tub bottom 11. Here, the non-porous inner tub 1 means that there is no hole communication between the inner tub and the outer tub of the pulsator washing machine 100, that is, there is no water between the inner tub and the outer tub in the washing process of the pulsator washing machine 100 (the pulsator washing machine of the present invention may have no outer tub, which may be referred to herein as a case), thereby saving water, avoiding waste of water resources, and at the same time, avoiding dirt and scale between the tub walls of the inner tub and the outer tub, reducing bacterial growth, and effectively avoiding secondary pollution of laundry.

At least a portion of the sealing disk 2 is rotatably provided at the bottom of the imperforate inner tub 1, and at least a portion of the sealing disk 2 is rotatable with respect to the imperforate inner tub 1 between an open position, in which the sealing disk 2 opens the drain hole 111, and a closed position, in which the sealing disk closes the drain hole 111.

The driving device 3 is respectively connected with the sealing disc 2 and the non-porous inner barrel 1, the driving device 3 is used for driving the non-porous inner barrel 1 and the sealing disc 2 to synchronously rotate so as to realize rotary washing of the pulsator washing machine 100, and the driving device 3 is used for driving the sealing disc 2 to rotate relative to the non-porous inner barrel 1 so as to realize rotation of the sealing disc 2 relative to the non-porous inner barrel 1 between an open position and a closed position.

Referring to fig. 1 to 5, when the pulsator washing machine 100 is in water, the driving device 3 drives the sealing plate 2 to rotate to the closed position to close the drain hole 111, the washing machine can be in water washing, and in the process of washing clothes, the driving device 3 can drive the non-porous inner tub 1 and the sealing plate 2 to rotate together; when the washing is completed, the driving device 3 drives the sealing disc 2 to rotate to an open position relative to the non-porous inner barrel 1, the water discharge hole 111 is communicated with the water passing hole 21, water in the non-porous inner barrel 1 can be discharged under the action of gravity, and in the dehydration process, water in the inner barrel is discharged out of the pulsator washing machine 100 through the water discharge hole 111 and the water passing hole 21.

According to the pulsator washing machine 100 of the embodiment of the invention, no water is communicated between the nonporous inner tub 1 and the outer tub in the washing process, so that water resources are saved, waste is reduced, and secondary pollution of clothes is avoided.

In some embodiments of the present invention, the sealing disk 2 has a water passing hole 21 thereon, and when the sealing disk 2 is in the open position, the water passing hole 21 communicates with the drain hole 111, and when the sealing disk 2 is in the closed position, the sealing disk 2 closes the drain hole 111; for example, the sealing plate 2 may be positioned at a closed position to close the drain hole 111 during the water intake and washing of the pulsator washing machine 100, so as to ensure the normal progress of the water intake and washing process; when water is required to be discharged after washing is completed, the sealing disk 2 is rotated to an open position, and the water passing hole 21 is communicated with the water discharging hole 111, so that water in the non-porous inner tub 1 can be discharged outside the washing machine through the water discharging hole 111 and the water passing hole 21.

In one embodiment of the present invention, as shown in fig. 2 and 3, a first sealing ring 51 may be provided between the sealing disk 2 and the bottom 11 of the non-porous inner tub 1, and both the drain hole 111 and the water passing hole 21 are located inside the first sealing ring 51 when the sealing disk 2 is in the open position. Thus, the connection position where the drain hole 111 and the water passing hole 21 are butted can be sealed by the first seal ring 51, water is prevented from leaking from the joint position of the drain hole 111 and the water passing hole 21, and the sealing performance of the pulsator washing machine 100 is improved.

It should be noted that, the rotation speed of the driving device 3 for driving the sealing disc 2 to rotate relative to the non-porous inner tub 1 is low, and the rotation angle of the sealing disc 2 between the open and closed positions is also small, so that when the driving device 3 drives the sealing disc 2 to rotate relative to the non-porous inner tub 1, the friction force applied to the first sealing ring 51 is small, and thus the reliability of the sealing between the drain hole 111 and the water passing hole 21 by the first sealing ring 51 can be greatly improved.

Further, referring to fig. 3, the first sealing ring 51 may be fixed at a position opposite to the bottom 11 of the non-porous inner tub 1, and when the driving device 3 drives the sealing disc 2 to rotate relative to the non-porous inner tub 1, the sealing disc 2 rotates relative to the first sealing ring 51, and the first sealing ring 51 surrounds the drain hole 111, so that the first sealing ring 51 may seal one turn around the drain hole 111, thereby further improving reliability of the connection position between the drain hole 111 and the water passing hole 21 by the first sealing ring 51, and improving sealing performance.

Preferably, referring to fig. 2 and 4, the sealing disk 2 may be coaxial with the imperforate inner tub 1. Therefore, the driving device 3 can conveniently drive the sealing disc 2 and the non-porous inner barrel 1 to synchronously rotate, and the driving device 3 can conveniently drive the sealing disc 2 to rotate relative to the non-porous inner barrel 1, so that the transmission structure between the driving device 3 and the sealing disc 2 and between the driving device 3 and the non-porous inner barrel 1 is simplified.

Further, a second sealing ring 52 may be disposed between the sealing plate 2 and the bottom 11 of the non-porous inner tub 1, the second sealing ring 52 may surround the axes of the sealing plate 2 and the non-porous inner tub 1, and both the drain hole 111 and the water passing hole 21 may be located outside the second sealing ring 52. That is, in the radial outward direction along the central axis of the imperforate inner tub 1, the drain hole 111 and the water passing hole 21 are both located at the outer side of the second sealing ring 52, so that in the process of draining water, the first sealing ring 51 is provided between the drain hole 111 and the water passing hole 21 to perform a first resealing protection, preventing water leakage from a gap between the drain hole 111 and the water passing hole 21, and the second sealing ring 52 is provided between the drain hole 111 and a transmission shaft (e.g., the second output shaft 322 of the clutch shown in fig. 2) to perform a second resealing protection, further preventing water leakage in the radial direction of the sealing disc 2, thereby further improving the sealing reliability of the pulsator washing machine 100, preventing water leakage to the transmission shaft position, ensuring that the driving device 3 can normally drive, avoiding the occurrence of a leakage hazard or corrosion of the transmission shaft.

As shown in fig. 1 to 5, in some embodiments of the present invention, the sealing plate 2 may be located at the outer side of the bottom 11 of the non-porous inner tub 1, and in combination with fig. 2 to 5, the sealing plate 2 is located at the lower side of the bottom 11 of the non-porous inner tub 1, and during the draining process, water in the non-porous inner tub 1 flows out through the drain hole 111 and then the water passing hole 21, thereby, the sealing plate 2 may be prevented from occupying the inner space of the non-porous inner tub 1, and the washing capacity of the pulsator washing machine 100 is ensured, so that the structure of the pulsator washing machine 100 may be more compact and reasonable.

Further, as shown in fig. 2 and 3, the bottom 11 of the non-porous inner tub 1 may be connected with a connection pad 4, the connection pad 4 is connected with the bottom 11 of the non-porous inner tub 1, and the connection pad 4 is fixed at a position opposite to the bottom 11 of the non-porous inner tub 1, and the connection pad 4 is connected with the driving device 3. Thereby, the driving shaft of the driving device 3 can drive the nonporous inner barrel 1 to rotate through the driving connecting disc 4 so as to realize rotary washing. For example, the tub bottom 11 of the non-porous inner tub 1 may be screw-coupled with the connection pad 4, and the connection pad 4 is screw-coupled with the driving shaft of the driving device 3 (e.g., the first output shaft 321 of the clutch shown in fig. 2), whereby the installation and the disassembly of the tub bottom 11 with the connection pad 4 can be facilitated, the installation and the disassembly of the connection pad 4 with the driving device 3 can be facilitated, and the structure of the non-porous inner tub 1 can be simplified, and the manufacturing can be facilitated.

Further, as shown in fig. 2 and 3, the connection pad 4 may be located under the bottom 11 of the non-porous inner tub 1, and the sealing pad 2 may be located between the connection pad 4 and the bottom 11 of the non-porous inner tub 1. At this time, the bottom 11 of the non-porous inner tub 1 is located above the sealing plate 2, so that the upward displacement of the sealing plate 2 can be limited, and the connecting disc 4 is located below the sealing plate 2, so that the downward displacement of the sealing plate 2 can be limited, that is, the bottom 11 of the non-porous inner tub 1 and the connecting disc 4 together define the displacement of the sealing plate 2 in the up-down direction, thereby achieving the effect of fixing the sealing plate 2.

It should be noted that, the bottom 11 of the non-porous inner tub 1 and the connecting disc 4 are limited only in the up-down direction of the sealing disc 2, and the sealing disc 2 is in a free state in the circumferential direction, that is, the sealing disc 2 can rotate relative to the bottom 11 of the non-porous inner tub 1 and the connecting disc 4 to realize rotation between the open position and the closed position while overcoming the friction force between the bottom 11 of the non-porous inner tub 1 and the connecting disc 4.

In some embodiments, referring to fig. 7 to 10, a third sealing ring 53 may be connected between the periphery of the connection disc 4 and the tub bottom 11 of the non-porous inner tub 1, the third sealing ring 53 may extend along the periphery of the connection disc 4, and the connection disc 4 may have a through hole 41 thereon, and the through hole 41 communicates with the drain hole 111 when the sealing disc 2 is in the open position, so that water in the non-porous inner tub 1 may sequentially pass through the drain hole 111, the water passing hole 21, and the through hole 41 when the sealing disc 2 is in the open position, and then be discharged to the outside of the washing machine. By providing the third sealing ring 53, water can be effectively prevented from flowing out from the gap between the connection pad 4 and the bottom 11 of the non-porous inner tub 1, thereby improving the reliability of sealing between the connection pad 4 and the bottom 11 of the non-porous inner tub 1. Furthermore, the connection plate 4 is fixedly connected with the non-porous inner tub 1, for example, the connection plate 4 can be screwed with the tub bottom 11 of the non-porous inner tub 1. That is, there is relatively no rotation between the connection disc 4 and the non-porous inner tub 1, and thus, the third sealing ring 53 provided between the connection disc 4 and the non-porous inner tub 1 is a static seal, and the sealing performance is more reliable.

In other embodiments of the present invention, as shown in fig. 17 to 19, the sealing disk 2 may include a turntable 24 and a vane 25, the vane 25 being connected to the turntable 24, and the vane 25 extending outward in a radial direction of the turntable 24, the vane 25 closing the drain hole 111 when the sealing disk 2 is in a closed position, the pulsator washing machine 100 may wash water, and the vane 25 being staggered with the drain hole 111 to open the drain hole 111 when the sealing disk 2 is in an open position, at which time the pulsator washing machine 100 may drain water. Thereby, the drain hole 111 can be opened and closed by the vane 25 by controlling the rotation of the sealing disk 2, thereby achieving the switching of the imperforate inner tub 1 between the washing of the inflow water and the drainage water.

Preferably, the open position and the closed position may each include a plurality, and the plurality of open positions and the plurality of closed positions may be staggered along a circular locus of rotation of the sealing disk 2. That is, a closed position is provided between the adjacent two open positions, whereby when the sealing disk 2 is in the closed position, the sealing disk 2 can be rotated to the open position by either clockwise rotation or counterclockwise rotation, so that the flexibility of switching the open and closed positions of the sealing disk 2 can be improved.

Preferably, as shown in fig. 20 and 21, the drain hole 111 may include a plurality of drain holes 111 spaced apart along the circumference of the tub bottom 11 of the non-porous inner tub 1, and the vane 25 may include a plurality of drain holes 111. Thus, the plurality of drain holes 111 may be simultaneously opened or the plurality of drain holes 111 may be simultaneously closed by using the drain holes 111 and the vane 25 in one-to-one correspondence, and furthermore, the drainage efficiency of the non-porous inner tub 1 may be improved by providing the plurality of drain holes 111.

In some embodiments of the present invention, as shown in fig. 2 to 5, 12 and 13, a connection disc 4 may be connected to the bottom 11 of the non-porous inner tub 1, and the connection disc 4 may be fixed with respect to the bottom 11 of the non-porous inner tub 1, and when the driving device 3 drives the connection disc 4 to rotate, the connection disc 4 may drive the non-porous inner tub 1 to rotate together, and further, the sealing disc 2 is located between the connection disc 4 and the bottom 11 of the non-porous inner tub 1. Therefore, the bottom 11 of the non-porous inner barrel 1 and the connecting disc 4 can jointly limit the displacement of the sealing disc 2 along the up-down direction, so that the effect of fixing the sealing disc 2 is achieved, at the moment, the sealing disc 2 is in a free state along the circumferential direction, and on the premise of overcoming the friction force between the bottom 11 of the non-porous inner barrel 1 and the connecting disc 4, the sealing disc 2, the bottom 11 of the non-porous inner barrel 1 and the connecting disc 4 rotate relatively, so that the sealing disc 2 rotates between an open position and a closed position.

Advantageously, as shown in fig. 14 to 16 and 22 to 24, the upper surface of the connection pad 4 may be provided with a support rib 43 extending in the circumferential direction of the connection pad 4, and at least a portion of the support rib 43 may be gradually increased in the circumferential height of the connection pad 4, and the blade 25 may be supported on the support rib 43 when the sealing pad 2 is in the closed position. Therefore, the supporting ribs 43 can support the blades 25 upwards, the strength of the blades 25 is improved, and the problem that the blades 25 incline downwards under the action of water pressure to cause the sealing of the drain holes 111 to fail is avoided.

Advantageously, as shown in fig. 21, when the sealing disk 2 is in the open position, the blades 25 may be staggered from the support ribs 43 so that the drain holes 111 may be opened, facilitating the drainage of water in the imperforate inner tub 1 through the drain holes 111.

In some embodiments of the present invention, as shown in fig. 14 to 16, the support rib 43 may have a shape that gradually increases and then gradually decreases along the circumferential height of the connection disc 4, and the vane 25 may be supported at the highest point of the support rib 43 when the sealing disc 2 is in the closed position. Thereby, during the process of rotating the sealing disk 2 from the open position to the closed position, the two ends of the supporting rib 43 can play a role of guiding the blade 25 and gradually push up the blade 25, when the blade 25 rotates to the highest point of the supporting rib 43, and when the blade 25 is completely supported on the supporting rib 43, the supporting rib 43 supports the blade 25 upwards and pushes the blade 25 against the first sealing ring 51 and the second sealing ring 52 on the bottom 11 of the aporate inner barrel 1, thereby realizing the sealing of the drain hole 111.

In some embodiments of the present invention, as shown in fig. 21, the drain holes 111 may include a plurality of drain holes 111 spaced apart along the circumference of the tub bottom 11 of the imperforate inner tub 1, and the blades 25 may include a plurality of corresponding to the plurality of drain holes 111, the support ribs 43 may include a plurality of groups corresponding to the plurality of blades 25 one by one, and each group of support ribs 43 may include only one, or each group of support ribs 43 may further include a plurality of ribs spaced apart along the radial direction of the connection disk 4, for example, each group of support ribs 43 may include two, three, four, five, etc. spaced apart along the radial direction of the connection disk 4, whereby the supporting effect of each group of support ribs 43 on the blades 25 may be enhanced, the strength of the blades 25 may be further improved when the sealing disk 2 is in the closed position, and the blades 25 may be ensured to effectively seal the drain holes 111.

In some embodiments of the present invention, as shown in fig. 14 to 16, a first limit rib 44 and a second limit rib 45 may be provided on an upper surface of the connection disc 4, the first limit rib 44 and the second limit rib 45 being spaced apart along a circumference of the connection disc 4, the vane 25 being rotatably provided between the first limit rib 44 and the second limit rib 45 between positions of closing and opening the drain hole 111, the vane 25 being abutted against the first limit rib 44 when opening the drain hole 111, and the vane 25 being abutted against the second limit rib 45 when closing the drain hole 111. Thereby, the rotation angle and the rotation range of the vane 25 can be effectively limited, and the vane 25 is limited to rotate only between the first limit rib 44 and the second limit rib 45, so that the failure of opening or closing the drain hole 111 due to excessive rotation of the vane 25 in the process of opening and closing the drain hole 111 is avoided.

Preferably, as shown in fig. 20 and 21, the blades 25 may include a plurality of first limiting ribs 44 spaced around the turntable 24, the connection disc 4 is provided with a plurality of first limiting ribs 44 corresponding to the plurality of blades 25, and the connection disc 4 is provided with a second limiting rib 45 corresponding to the plurality of blades 25, that is, each blade 25 is correspondingly provided with a first limiting rib 44 and a second limiting rib 45, so that the first limiting ribs 44 and the second limiting ribs 45 can limit two ends of each blade 25 along the rotation direction, thereby ensuring the rotation precision of the blades 25, and ensuring that the blades 25 can completely open the drainage holes 111 or completely seal the drainage holes 111.

In other embodiments of the present invention, as shown in fig. 6 to 10, the sealing disk 2 may be located inside the bottom 11 of the non-porous inner tub 1.
