Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, and specifically relates to a washing device. Background Technology

[0002] With increasing health concerns, shared apartments are generally equipped with washing machines. However, due to the large number and variety of users, cross-contamination of clothing among different individuals is a concern. Even in ordinary household washing machines, cross-contamination can occur if clothes are washed together. Most washing machines currently have only one washing tub, and placing adult clothes, children's clothes, underwear, socks, etc., in the same tub clearly does not meet health and hygiene requirements. Therefore, in recent years, the market has seen a clear trend towards categorized washing in washing machines. One type is the multi-tub washing machine: this is achieved by having two or three washing tubs in one machine structure, with water circuits isolated between the tubs to wash different types of clothing separately. Another type is the tub-within-a-tub technology: a small, easily removable tub is placed inside the large tub of the pulsator washing machine, with water circuits isolated from the large tub to wash different types of clothing separately. However, this technology has the following drawbacks: 1. Only the small tub inside the large tub can be replaced; the large tub itself cannot be easily disassembled and replaced. Therefore, the size of the replaceable inner tub is limited by the size of the large tub, thus limiting the washing capacity. 2. Because the replaceable small tub does not contain a washing impeller, the washing effect is not as good.

[0003] Patent CN201810337863.6 discloses a washing machine with a replaceable inner tub. An inner tub positioning bushing is fixedly installed at the bottom of the inner tub, and an inner tub positioning shaft is fixedly installed on the clutch. The two are fitted with a clearance to ensure accurate guidance and positioning when the inner tub is engaged with the clutch. The clutch is equipped with a washing shaft and a spin-drying shaft. The top of the washing shaft has a lower component of a quick-connect fitting, and the bottom of the impeller shaft has an upper component of a quick-connect fitting, allowing for quick engagement or disengagement. The upper component and lower component of the spin-drying drive disc are connected by a snap-fit ​​mechanism with interlocking upper and lower hook grooves, preventing them from disengaging during rotation. The aforementioned patent features a detachable snap-fit ​​rotating connection fixing structure along the torque transmission path of the washing shaft. This means the washing tub is only axially fixed, making the tub's fixation unstable, especially during the spin-drying process, which carries the risk of the tub being thrown out. Furthermore, replacing the washing tub is quite difficult, as the lower and upper components of the quick-connect fitting for the washing shaft are located below the washing area, preventing the user from seeing the engagement point from above, resulting in time-consuming and laborious installation.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0034] See Figures 1-18This is an embodiment of a washing device proposed in this invention. The washing device 100 includes: a support frame 10, a washing tub 20, a handle 30, a locking structure 40, and a pull rod 50. The support frame 10 is installed inside the washing device, and the washing tub 20 is detachably installed inside the support frame 10, so that the washing tub 20 can be replaced. Furthermore, the contact area between the washing tub 20 and the support frame 10 is relatively large, which is more conducive to fixing the washing tub 20.

[0035] In this embodiment, a handle 30 is provided on the washing tub 20 for lifting the washing tub 20. The handle 30 facilitates the installation, disassembly, and movement of the washing tub 20. After disassembly, the washing tub 20 can be replaced with another washing tub, enabling replacement of the washing tub 20. A locking structure 40 is provided between the washing tub 20 and the support frame 10 to fix the washing tub 20 to the support frame 10, increasing the stability of the washing tub 20 after installation. After the washing tub 20 is fixed, the locking structure 40 is in a locked state; when disassembling the washing tub 20, the locking structure 40 needs to be in an unlocked state. To simplify the unlocking operation of the locking structure 40, a linkage between the handle 30 and the locking structure 40 can be provided; a pull rod 50 is provided between the handle 30 and the locking structure 40, which can push the locking structure 40 to unlock.

[0036] In this embodiment, the washing tub 20 is detachably mounted and fixed on the support frame 10, which is installed inside the outer tub 60. The large contact area between the washing tub 20 and the support frame 10 facilitates the fixation of the washing tub 20. The locking structure 40 ensures good stability of the washing tub 20 after installation. Furthermore, the handle 30 is linked to the locking structure 40; the pull rod 50 can push the locking structure 40 to unlock it. In other words, the movement of the handle 30 moves the pull rod 50, which in turn pushes the locking structure 40, allowing it to be unlocked via the handle 30, thus saving the unlocking operation.

[0037] In some embodiments of this application, when disassembling the washing tub 20, the handle 30 is lifted upwards; the handle 30 drives the pull rod 50 to move, and the pull rod 50 pushes the locking structure to move, thereby unlocking the locking structure 40; and the push on the locking structure 40 can be maintained so that the locking structure 40 is in the unlocked state.

[0038] In some embodiments of this application, see Figure 8-9 , Figure 16As shown, the locking structure 40 has a locking rod 41 on the washing tub 20 and a locking slot 42 on the support frame 10. A lock head 411 is provided at the end of the locking rod 41, which passes through the locking slot 42 and engages with it. The locking rod 41 is hinged, and the lock head 411 can be unlocked by rotating the locking rod 41. In this embodiment, the locking slot 42 has a through hole in the vertical direction, and the lock head 411 engages with the lower edge of the locking slot 42. In other embodiments, a locking groove that engages with the lock head 411 can also be provided within the locking slot 42.

[0039] In some embodiments of this application, a handle 30 is hinged to the washing tub 20. The handle 30 has a placed state and a lifted state, and can be rotated to switch between the two states. When the handle 30 rotates from the placed state to the lifted state, it drives the pull rod 50 to move, which in turn pushes the locking rod 41 to rotate and move, thus unlocking the tub. When it is necessary to disassemble the washing tub 20, the handle 30 is rotated from the placed state to the lifted state, that is, by lifting the handle 30 and rotating it upwards. At this time, the locking structure 40 is unlocked and can be kept in the unlocked state; then, the washing tub 20 is lifted vertically upwards to disassemble it. Therefore, disassembling the washing tub 20 is simple; just pull the handle 30 upwards. The action of pulling the handle 30 involves two steps: first, pull the handle 30 upwards and rotate it to move it from the placed state to the lifted state, unlocking the locking structure 40; then, pull the handle 30 vertically upwards to remove the washing tub 20 from the support frame 10. For installing the washing tub 20, pull the handle 30 upwards, unlocking the locking structure 40 and lifting the washing tub 20; then place the washing tub 20 into the support frame 10; finally, rotate the handle 30 from the lifted state to the placed state.

[0040] In some embodiments of this application, a handle 30 is hinged to the washing tub 20, and a pull rod 50 is hinged to the handle 30. When the handle 30 rotates, the pull rod 50 moves accordingly. A locking rod 41 is hinged to the washing tub 20 and has a force-receiving part 412 that cooperates with the pull rod 50. When the pull rod 50 moves with the handle 30, it pushes the force-receiving part 412 to move, thereby unlocking the locking rod 41. There is no connection between the pull rod 50 and the locking rod 41; therefore, when the pull rod 50 moves with the handle 30, it undergoes an arc-shaped translation.

[0041] In some embodiments of this application, the pull rod 50 is provided with a push pawl 51, and a force-receiving groove matching the push pawl 51 is formed on the force-receiving part 412. The push pawl 51 extends into the force-receiving groove, which restricts the movement of the push pawl 51. The push pawl 51 has an inclined mating surface 511. When the locking structure 40 is in the unlocked state, the mating surface 511 abuts against the bottom of the force-receiving groove, thereby increasing the contact area between the push pawl 51 and the force-receiving part 412, ensuring that the push pawl 51 can push the locking rod 41 into the unlocked state.

[0042] In some embodiments of this application, the locking structure 40 has two locking rods 41 arranged opposite each other, an elastic element 43 for pushing the two locking rods 41 into a locked state, two pull rods 50, and two adjacent handles 30. A mounting base 24 is provided on the washing tub 20, and the two locking rods 41 are hinged to the mounting base 24, with two lock heads 411 extending close to each other. A mounting post 241 for mounting the elastic element 43 is provided on the mounting base 24. The elastic element 43 is a torsion spring, having an elastic body sleeved on the mounting post 241 and two protruding elastic claws, which are respectively fixed to the two locking rods 41. The elastic claws are fixed at the end of the locking rod 41 near the lock head 411, or rather, away from the hinge axis, which helps to increase the lever arm of the elastic force.

[0043] In some embodiments of this application, the washing tub 20 has a tub body 21 and a tub lid 22 covering the upper end of the tub body 21, with an openable and closable inner lid 23 on the tub lid 22. The tub lid 22 has a lid edge 221 located outside the tub body 21, and a through hole 2211 for the pull rod 50 to pass through is formed on the lid edge 221. The handle 30 is arc-shaped and matches the lid edge 221. When the handle 30 is in the placed state, the handle 30 rests flat on the lid edge 221. When the handle 30 is flat on the lid edge 221, the handle 30 is in the placed state; when the handle 30 is vertical, the handle 30 is in the lifted state.

[0044] In some embodiments of this application, multiple drain holes 211 are provided at the upper end of the tub wall of the tub body 21. The cover edge 221 has a horizontally arranged annular body 2212 and a vertically arranged skirt 2213. The skirt 2213 is composed of alternating convex arc surfaces 22131 and concave arc surfaces 22132. The convex arc surface 22131 is provided on the outside of the drain holes 211. The washing tub 20 is a holeless washing tub. The drain holes 211 are provided at the upper end of the tub wall of the tub body 21 to allow the washing water in the washing tub 20 to be thrown upwards and discharged from the drain holes 211. By providing the convex arc surface 22131, the space outside the drain holes 211 is opened up to allow the washing water to be discharged.

[0045] In some embodiments of this application, the hinge shaft 31 of the handle 30 and the hinge shaft 52 of the pull rod 50 are spaced apart, and the handle 30 is provided with a hinge protrusion 32 that hinges to the pull rod 50. When the handle 30 is in the placed state, the hinge protrusion 32 is located below the hinge shaft 31 of the handle 30, and the pull rod 50 is at its lower end. When the handle 30 is rotated to the lifted state, the handle 30 has rotated 90°, and the pull rod 50 is in a position horizontal to the hinge shaft 31, and the pull rod 50 rotates and translates upwards.

[0046] In some embodiments of this application, the tub lid 22 further includes a lid body 222 located inside the tub body 21, and a raised edge 223 connecting the lid body 222 and the lid edge 221. A receiving groove matching the upper end of the tub body 21 is formed on the raised edge 223; the upper end of the tub body 21 extends into the receiving groove. Multiple downwardly extending positioning posts 212 are provided at the bottom of the tub body 21, and positioning grooves 111 matching the positioning posts 212 are formed on the support frame 10. By extending the positioning posts 212 into the positioning grooves 111, the bottom of the washing tub 20 and the bottom of the support frame 10 can be positioned relative to each other.

[0047] In some embodiments of this application, the support frame 10 has a base 11, an upper edge 12, and a plurality of shelf plates 13 spaced apart between the base 11 and the upper edge 12. A matching groove 213 is formed on the wall of the tub 21 to mate with the shelf plates 13. The upper end of each shelf plate 13 has an outwardly folded edge 131, the outer end of which is connected to the upper edge 12. A locking slot 42 is formed on the folded edge 131. The adjacent shelf plates 13 are spaced apart in the upward direction, which facilitates the installation of the washing tub 20.

[0048] In some embodiments of this application, the upper edge 12 is located below the lid 22; a balance ring 14 is provided on the support frame 10, and the upper edge 12 is a groove with an opening at the bottom. The upper end of the balance ring 14 is located inside the upper edge 12, and a plurality of clearance grooves 141 for avoiding fasteners are provided on the balance ring 14.
