Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and more specifically, relates to a washing tub assembly and a pulsator washing machine. Background Art

[0002] In the prior art, with the improvement of living standards, people have higher and higher requirements for washing equipment. They even hope that the same washing equipment can wash various types of clothes, or can distinguish the clothes of different family members to prevent cross-contamination. For a household with only one washing equipment, it is necessary to clean the washing tub before and after washing the clothes of different members or different types of clothes, which is troublesome to operate.

[0003] In the existing solutions, to solve the above problems, multiple washing tubs are equipped in one washing equipment, and the washing tubs are detachably arranged in the washing equipment to achieve separate tub washing. By setting the middle and lower parts of the washing tub to be porous-free, water can be independently contained for washing. Drainage holes are provided on the outer peripheral wall of the upper opening. When the washing tub rotates at a high speed, water is drained from the dehydration holes, meeting the requirement that one washing equipment has multiple washing partitions.

[0004] Chinese Patent with application number CN 201721197718.X discloses a washing tub assembly, including: an inner tub, the tub body of the inner tub has a first open end, and the tub body has a structure for cooperating with the middle tub; a middle tub, the tub body of the middle tub has a second open end, a balance ring is provided at the second open end, and the tub body has a structure for cooperating with the inner tub; the barrel wall of the inner tub inclines outward at a predetermined angle; the inner tub is located inside the middle tub, and the two are detachably connected, and the tub bodies of the two are in contact and cooperate so that the two can rotate synchronously. The inner tub is replaceable, and each user can use their own inner tub. During the laundry process, the tub body of the inner tub forms an independent space, and the clothes are in an isolated state during the laundry process, which can ensure the cleanliness of the clothes and the hygiene and safety during the laundry process. However, although the washing tub of this solution is replaceable, a middle tub is additionally provided, the structure is complex, and the cost is high. Only drainage holes are provided above the water level line of the inner tub, and water is drained through the high-speed rotation of the inner tub in cooperation with the drainage holes. The drainage speed is slow, and large-scale rapid drainage needs to be achieved, and the water level in the washing tub cannot be automatically sensed, which is water-consuming and power-consuming.

Detailed Embodiments

[0061] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0062] In the description of the present invention, it should be noted that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0063] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0064] As Figures 1 to 9 shown, the present invention also provides a washing tub assembly, which can realize convenient and rapid replacement of the inner tub 1, achieve partitioned washing, and avoid cross-contamination.

[0065] The washing tub assembly includes an inner tub 1 and a support frame 2.

[0066] One end of the inner tub 1 has an opening, and a balance ring 11 is provided. The peripheral wall of the inner tub 1 above the highest water level is provided with dehydration holes 16. The support frame 2 has a receiving cavity, and one end of the receiving cavity is provided with a communicating inlet. The inner tub 1 is detachably fixed in the receiving cavity of the support frame 2 and is circumferentially limited with the support frame 2. The bottom of the inner tub 1 enters the receiving cavity through the inlet. When the washing machine 7 is dehydrating, it drives the water flow to rise along the inner peripheral wall of the inner tub 1 and is discharged through the dehydration holes 16.

[0067] By adding the support frame 2 in the present invention, the support frame 2 can be rotatably fixed in the outer tub 4 of the washing machine 7, and the inner tub 1 can be detachably fixed in the support frame 2, reducing the space occupied by the support frame 2 in the washing machine 7. A balance ring 11 is provided at the open end of the inner tub 1, which can increase the washing capacity of the inner tub 1. The support frame 2 can play a role in fixing the inner tub 1. The structure has a small volume and low cost, and can realize replacing the inner tub 1 to wash clothes separately and avoid cross-infection.

[0068] The washing tub assembly further includes a water stop member 3. The bottom of the inner tub 1 and the corresponding support frame 2 are respectively provided with a water permeable hole 12 and a mounting hole 21. The water stop member 3 is disposed in the water permeable hole 12 for opening or closing the water permeable hole 12. The mounting hole 21 allows a part of the structure of the driving device 5 of the washing machine 7 to move and extend into the mounting hole 21 to drive the water stop member 3 in the water permeable hole 12 to move and open or close the water permeable hole 12.

[0069] In the present invention, a water permeable hole 12 and a mounting hole 21 are sequentially provided on the opposite sides of the bottom of the inner tub 1 and the support frame 2. A water stop member 3 is disposed in the water permeable hole 12. By providing a driving device 5 on the washing machine 7, the water stop member 3 can be driven to close the water permeable hole 12 or open the water permeable hole 12 for drainage, so that the inner tub 1 can both hold water for washing and quickly complete drainage, improving the washing efficiency.

[0070] The axial height of the support frame 2 is much smaller than the axial height of the inner tub 1. The barrel of the inner tub 1 is arranged in a flared and inclined manner so that the water in the inner tub 1 can be easily discharged during dehydration.

[0071] As Figures 1 to 3 shown, on the inner peripheral side of the accommodation cavity of the support frame 2, there are protrusions 22 extending to both axial ends. On the outer peripheral wall at the bottom end of the inner tub 1, there is a recessed sliding groove 14 extending along the axial direction. The sliding groove 14 is slidably clamped on the protrusions 22 inside the support frame 2 from the inlet end of the accommodation cavity, which not only facilitates the quick disassembly and assembly of the inner tub 1 and the support frame 2, but also can prevent the inner tub 1 from rotating circumferentially relative to the support frame 2, preventing the inner tub 1 from rotating, shifting, and shaking.

[0072] At the opening of the inner tub 1, there is a balance ring 11. On the outer peripheral wall at the open end of the inner tub 1, there is a rotatable handle 15 located on the outer periphery of the balance ring 11, and the inner tub 1 can be lifted out of the washing machine 7 through the handle 15.

[0073] The bottom of the inner tub 1 has a flange 13. The water permeable holes 12 extend outward and protrude on the flange 13. The edge of the flange 13 folds and extends towards the bottom wall 23 of the support frame 2 to form a folded edge 131, and the folded edge 131 extends outward beyond the water stop plug. The bottom wall 23 inside the support frame 2 has an annular concave cavity 231, and the folded and extended part of the flange 13 is inserted into the annular concave cavity 231.

[0074] In the present invention, by arranging the water permeable holes 12 on the flange 13 and the folded edge 131 on the outer periphery of the flange 13 extending outward beyond the water stop plug, it can not only increase the strength of the inner tub 1 of the washing machine 7, but also enable the inner tub 1 to be placed stably on the ground during assembly or transportation, and can also protect the water stop plug to avoid damage to the water stop plug.

[0075] The support frame 2 includes a bottom wall 23, a plurality of connecting arms 25, and an annular arm 24.

[0076] One ends of the plurality of connecting arms 25 are arranged at intervals along the circumferential direction on the outer peripheral edge of the bottom wall 23, and the other ends extend along the axial direction, or extend towards the opening side of the inner tub 1. The annular arm 24 is connected to the other ends of the plurality of connecting arms 25 to form the accommodation cavity. The protrusions 22 are arranged on the inner sides of the connecting arms 25. Preferably, the protrusions 22 are formed by protruding from the connecting arms 25 and the annular arm 24 at their connection parts from the outside to the inside.

[0077] Furthermore, the height of the support frame 2 is lower than the height of the dehydration holes 16 of the inner tub 1, which can facilitate the dehydration of the inner tub 1 and avoid the water separated from the dehydration holes 16 being reflected onto the support frame 2 and causing splashing.

[0078] Preferably, the height of the support frame 2 is lower than half of the height of the inner barrel 1, which can not only provide sufficient circumferential support to prevent the acting force of the inner barrel 1 from shaking outward in the circumferential direction, but also have sufficient strength in the axial direction.

[0079] Specifically, the height can be such that the upper edge of the support frame 2 is higher than one-fourth of the height of the inner barrel 1 and lower than three-fourths of the height of the inner barrel 1.

[0080] Preferably, the upper edge of the support frame 2 can be at a position higher than half of the height of the inner barrel 1 and lower than three-fourths of the height of the inner barrel 1, or the upper edge of the support frame 2 can be at a position higher than one-fourth of the height of the inner barrel 1 and lower than half of the height of the inner barrel 1.

[0081] As Figures 2 to 5 shown, the water stop member 3 includes a water stop plug, and the water stop plug is movably fixed in the water permeable hole 12 and is used to close or open the water permeable hole 12.

[0082] The support frame 2 has a bottom wall 23, and the bottom wall 23 is disposed opposite to the bottom of the inner barrel 1. A slideway 232 is provided on the bottom wall 23 outside the support frame 2. The mounting hole 21 is provided through the slideway 232. The mounting hole 21 and the water permeable hole 12 are disposed opposite to each other and are offset from the center of the bottom of the inner barrel 1. The slideway 232 extends along the circumferential movement track of the inner barrel 1 and is used to guide the driving device 5 to enter the mounting hole 21 and then drive the water stop member 3 to move.

[0083] In the present invention, by fixing a movable water stop plug in the water permeable hole 12, a slideway 232 is provided on the bottom wall 23 of the support frame 2, and the mounting hole 21 is provided on the slideway 232 and is disposed opposite to the water permeable hole 12; the washing tub assembly is installed in the washing machine 7, and a part of the structure of the driving device 5 of the washing machine 7 slides along the slideway 232 outside the support frame 2 and enters the mounting hole 21, and then moves inward to drive the water stop plug to move, so that the driving member 52 of the washing machine 7 can be quickly positioned and guided into the mounting hole 21 to quickly open or close the water permeable hole 12, reducing the operation difficulty and improving the operation efficiency.

[0084] The water stop plug can protrude outward from the water permeable hole 12 in the natural state.

[0085] As Figures 4 to 7 shown, where Figure 6 is a partial structure of the inner barrel 1. The bottom of the inner barrel 1 is installed in the support frame 2, and it is a schematic diagram of the water stop plug cooperating with the driving device 5 to open the water permeable hole 12. The water stop plug is axially telescopically inserted into the mounting frame 121 in the water permeable hole 12.

[0086] The water stop plug includes a plug head 32, a telescopic shaft 31, a mounting table 33, and a spring 34 that are connected in sequence. The telescopic shaft 31 is movably inserted into the mounting bracket 121. One end of the telescopic shaft 31 has a plug head 32, which is arranged inside the water permeable hole 12 and is used to close the water permeable hole 12. The other end of the telescopic shaft 31 has a mounting table 33. The outer diameters of the mounting table 33 and the plug head 32 are larger than the outer diameter of the telescopic shaft 31.

[0087] The spring 34 is sleeved on the outer periphery of the telescopic shaft 31 and is pressed between the mounting table 33 and the mounting bracket 121. When driving the water stop plug to move inward, the spring 34 is driven to move inward and compress, so that the plug head 32 moves away from the inner side of the water permeable hole 12 to open the water permeable hole 12; after stopping driving, the spring 34 rebounds to drive the water stop plug to move outward, so that the plug head 32 closes the water permeable hole 12.

[0088] The water permeable hole 12 extends a certain distance, and the hole diameter gradually decreases from the inside of the inner barrel 1 to the outside, and then remains unchanged and extends to the outside of the inner barrel 1.

[0089] The outer diameter of the plug head 32 gradually increases along the axial direction outward from the telescopic shaft 31, and matches the hole diameter of the water permeable hole 12 on the inner side, increasing the contact area with the hole diameter of the water permeable hole 12 and improving the sealing performance. Preferably, the plug head 32 is in the shape of an inverted cone.

[0090] Furthermore, the washing tub assembly further includes an outer tub 4 and a driving device 5.

[0091] The inner barrel 1 and the support frame 2 are synchronously rotatably arranged in the outer barrel 4. The driving device 5 includes a moving component, which is telescopically arranged inside and outside the outer barrel 4 and is used to drive the water stop component 3 to move inward to open the water permeable hole 12 or retract outward to block the water permeable hole 12 after extending into the installation hole 21.

[0092] Preferably, the washing tub assembly further includes a liquid level detection device 6.

[0093] The moving component includes a communicating pipe assembly 51, which is telescopically arranged inside and outside the outer barrel 4 and is used to be hermetically communicated with the water permeable hole 12 after extending into the installation hole 21 to drive the water stop component 3 to move. The liquid level detection device 6 is communicated with the communicating pipe assembly 51 and is used to be communicated with the inner barrel 1 to detect the liquid level in the inner barrel 1 when the communicating pipe assembly 51 opens the water permeable hole 12.

[0094] In the present invention, by providing a communicating pipe assembly 51, during the water inlet process of the washing machine 7, the driving device 5 drives the communicating pipe assembly 51 to extend inward into the mounting hole 21 and then drives the water stop plug to move inward to open the water permeable hole 12. At this time, the communicating pipe assembly 51 is in communication with the interior of the inner tub 1. The liquid level detection device 6 is in communication with the inner tub 1 through the communicating pipe assembly 51, and can automatically detect the liquid level in the inner tub 1, and more accurately control the water inlet volume of the washing machine 7.

[0095] When the water level in the inner tub 1 reaches the set water level, the liquid level detection device 6 sends a signal to the control board of the washing machine 7, and the control board sends a signal to the driving device 5 to drive the communicating pipe assembly 51 to move downward. After the water stop plug is reset, it closes the water permeable hole 12, and the washing machine 7 starts to perform subsequent tasks such as washing.

[0096] By providing a driving component 52, when the water permeable hole 12 is moved to be opened, the interior is in communication with the interior of the inner tub 1, and the liquid level detection device 6 communicating therewith can automatically detect the liquid level in the inner tub 1, more accurately control the water inlet volume, and facilitate the control of washing.

[0097] Preferably, an annular outer tub cover 43 is provided at the mouth of the outer tub 4, and the inner diameter of the outer tub cover 43 is larger than the outer diameter of the balance ring 11, which facilitates the detachable inner tub 1.

[0098] Further, one end of the communicating pipe assembly 51 has a ball seat 511a, and a rotatable ball 511b is installed in the ball seat 511a. An inlet 511c communicating with the interior of the communicating pipe assembly 51 is provided on the ball seat 511a on the outer periphery of the ball 511b for communicating with the water permeable hole 12. When the water permeable hole 12 is opened, the communicating pipe assembly 51 is in communication with the interior of the inner tub 1. One end of the communicating pipe assembly 51 also has an annular water sealing lip 511d provided on the outer periphery of the ball seat 511a for blocking the water permeable hole 12.

[0099] The communicating pipe assembly 51 is a telescopic and internally communicating pipe assembly.
