For another example, the blocking portion 142 can be moved linearly in a translational manner relative to the base portion 141. In some embodiments, referring to fig. 5 and 6, the on-off control mechanism 14 includes a bouncing core 143, the blocking portion 142 is located on the top side of the base portion 141, and the bouncing core 143 is connected between the base portion 141 and the blocking portion 142.

The bouncing core 143 includes a locked state in which the bouncing core 143 is compressed and the blocking portion 142 can be locked at a position for blocking the drainage passage 12b, and a pop-up state, see fig. 6. Referring to fig. 5, in the pop-up state, the pop-up core 143 pops up the blocking portion 142 to a position separated from the base portion 141 to open the drainage passage 12 b.

The blocking portion 142 can be forced to switch the bounce core 143 between a locked state and an ejected state by an external force pressing action.

The user can directly press the blocking part 141 from the washing area 12a, so that the user can conveniently operate the washing machine during the process of washing clothes by hands, and the convenience of the user is improved. The bounce core 143 is disposed between the base portion 141 and the blocking portion 142, and the bounce core 143 is shielded by the base portion 141 and the blocking portion 142, so that the possibility that a user directly observes the bounce core 143 is reduced, and user experience is improved.

In the locked state, the blocking portion 142 and the base portion 141 are completely fitted to close the drainage passage 12b, and the elastic member in the bound core 143 in the compressed state is in the charged state. When the user presses the blocking part 142, the bouncing core 143 is switched to the bouncing state, and the elastic member in the bouncing core 143 releases the accumulated energy, thereby pushing the blocking part 142 to move and separate from the base part 141, and communicating the drainage channel 12b with the washing area 12a, thereby realizing the drainage function. The blocking part 142 is ejected by the elastic force released in the process of switching the bouncing core 143 to the ejecting state, so that the situation that a user needs to directly pull out the blocking part 142 is avoided, and the user experience is improved.

It can be understood that the elastic force released by the bouncing core 143 during the switching to the bouncing state is required to be larger than the pressure applied to the blocking portion 142 in the washing zone 12a in the water-full state, so that the blocking portion 142 can overcome the water pressure to open the drainage channel 12 b.

It should be noted that the bouncing core 143 may adopt a structure form existing in the related art, and the detailed structure and the operation principle thereof are not described herein.

It can be understood that a seal ring is disposed at the bottom of the closing portion 141 to improve the sealing property between the closing portion 141 and the base portion 141 in the locked state, and to reduce the possibility of water leaking from the joint between the closing portion 141 and the base portion 141. It will be appreciated that the lid arrangement 12' is connected to the washing drum 11 via the lid 12.

The specific connection mode of the cover 12 and the washing drum 11 is not limited.

Exemplarily, in some embodiments, the lid 12 is detachably attached to the washing drum 11, and the lid 12 is attached to the washing drum 11 when the lid device 12' needs to close the laundry input opening 11 b; when the laundry inlet 11b needs to be opened, the lid 12 may be removed from the washing tub 11.

In other embodiments, lid 12 is hinged to washing drum 11, that is, lid 12 ' is always attached to washing drum 11 regardless of whether lid 12 ' is in a state of opening or closing laundry input opening 11b, and the user does not need to remove lid 12 ' from washing drum 11. For example, referring to fig. 7, a protruding column 1221 is formed at an edge of the drum cover 12, and the drum cover 12 is hinged to the washing drum 11 through the protruding column 1221.

For example, referring to fig. 2, the cover 12 is provided with a first fastening structure 1211, the washing drum 11 is provided with a second fastening structure, and the first fastening structure 1211 and the second fastening structure are detachably fastened.

The specific structural shapes of the first fastening structure 1211 and the second fastening structure are not limited as long as they can be reliably fastened and can be easily separated. For example, one of the first fastening structure 1211 and the second fastening structure is a locking groove, and the other is an elastic hook.

It should be noted that, in the embodiment where the cartridge cover 12 is detachably attached to the washing cartridge 11, the number of the first fastening structures 1211 is plural, and the number of the second fastening structures is also plural, and the cartridge cover 12 is detachably attached to the washing cartridge 11 by the fastening engagement of the plural first fastening structures 1211 and the plural second fastening structures.

In the embodiment where the cover 12 is hinged to the washing drum 11, the number of the first fastening structures 1211 can be one or more, and the number of the second fastening structures 1211 can be one or more, so that the cover 12 can be prevented from being turned upwards during the rotation process by the cooperation of the first fastening structures 1211 and the second fastening structures.

For example, referring to fig. 1 to 4, the washing drum 11 includes a drum body 111 and a balance ring 113, wherein the balance ring 113 is disposed inside an upper end of the drum body 111. The balance ring 113 is used to adjust the eccentric rotation of the washing tub 11. It is understood that the balancing ring 113 may employ any one of the existing balancing techniques, and is not limited thereto.

The gimbal ring 113 directly or indirectly carries the cartridge cover 12. That is, the balance ring 113 needs to bear the weight of the lid 12 and the load of the lid 12. The balance ring 113 has a greater thickness in the radial direction than the cylinder 111, and thus, the top side of the balance ring 113 has a larger supporting area and mounting area, facilitating the mounting of the cylinder cover 12. For example, referring to fig. 1, when the cover 12 is in the folded state of not extending downward, the cover 12 is located higher than the gimbal 113.

Illustratively, in some embodiments, the cartridge cover 12 rests directly on top of the gimbal 113.

In other embodiments, referring to fig. 1 to 4, the washing drum 11 includes a drum ring 114 surrounding the drum body 111, the drum ring 114 is located above the balance ring 113 and abuts against the balance ring 113, and the balance ring 113 provides a supporting and mounting position for the drum ring 114. Cartridge cover 12 is supported and attached to cartridge collar 114, that is, in this embodiment, cartridge collar 114 provides support and location for cartridge cover 12. In this embodiment, the structures of the cylinder 111 and the balance ring 113 are not required to be changed, the existing production process can be used for the cylinder 111 and the balance ring 113, and only the structure of the cylinder ring 114 needs to be designed adaptively, so that the production cost is reduced.

Illustratively, the inner diameter of the cartridge ring 114 is smaller than the inner diameter of the balance ring 113, so that the possibility of collision and interference between the cartridge cover 12 and the balance ring 113 can be reduced.

It should be noted that a drain hole may be provided in the bottom wall of the washing zone 12a, and the drain hole may be sealed by a sealing plug. When the user manually washes in the washing zone 12a, or only automatically washes without dehydration, the water in the washing zone 12a may be discharged through the washing chamber 11a by pulling out the sealing plug and entering the washing chamber 11a through the drain hole.

Referring to fig. 1-4, for example, the collar 114 is provided with a ring groove 114a surrounding the cover 12, and the ring groove 114a can receive water removed from the washing zone 12a during the dewatering process. The radially outer side wall of the ring groove 114a is provided with dewatering holes 114b, and the water extracted from the washing zone 12a received by the ring groove 114a can be discharged to the outside of the washing tub 11 through the dewatering holes 114 b. That is, during the dehydration process, the cover 12 discharges the dehydrated water to the outside of the washing drum 11 through the drum ring 114, i.e. the water dehydrated in the washing zone 12a does not flow into the washing chamber 11a, so that the water dehydrated in the washing zone 12a during the dehydration process can be prevented from flowing into the washing chamber 11a to affect the dehydration effect and dehydration efficiency of the laundry in the washing chamber 11 a.

Referring to fig. 1 to 4, the top side of the ring groove 114a is open for receiving the water flow, and the collar 114 is provided with a water hole 114c, and the water hole 114c communicates the ring groove 114a and the washing chamber 11 a. Referring to fig. 3, the water flows into the ring groove 114a from above and enters the washing chamber 11a through the water holes 114c to fill the washing chamber 11a with water. In this embodiment, whether the washing tub 11 is a perforated inner tub or a non-perforated inner tub, the normal injection of the washing water into the washing tub 11 can be realized.

It will be appreciated that in the embodiment where the washing drum 11 is a perforated washing drum 11, the outer tub 13 may be directly filled with water.

It is understood that in the embodiment in which both the dewatering holes 114b and the water through holes 114c are provided, the water through holes 114c are located lower than the dewatering holes 114 b.

The specific structure of the cartridge cover 12 is not limited.

For example, referring to fig. 5, 6, 7 and 8, the cover 12 includes a support ring 121 and a telescopic member 122 disposed on the support ring 121, the cover 12 is supported on the washing drum 11 through the support ring 121, and the telescopic member 122 can be vertically telescopic relative to the support ring 121. The support ring 121 serves to carry the own weight of the telescopic member 122 and the load of the washing zone 12a, and therefore, the support ring 121 needs to have appropriate structural strength. For example, the support ring 121 is made of metal, rigid plastic, or the like.

The specific configuration of the extensible member 122 is not limited as long as it can be appropriately extended and contracted and can reliably contain water.

Illustratively, the bellows 122 is a bellows. When the corrugated pipe is in a downward extending state, the outer diameter of the corrugated pipe is sequentially reduced from top to bottom, and when the corrugated pipe is in an unstretched state, the corrugated pipe is sequentially nested in the radial direction so as to be accommodated in a circular space surrounded by the cylinder ring 114 as much as possible.

In some embodiments, the bellows and the support ring 121 are integrally formed as a plastic member, wherein the material of the bellows and the material of the support ring 121 may be the same or different. In the embodiment with the same material, the thickness of the support ring 121 is greater than that of the corrugated tube, so that the support ring 121 has a higher structural strength and is not easy to deform, and the thickness of the corrugated tube is relatively thin to meet the requirement of the expansion performance. In embodiments with different materials, the support ring 121 and the bellows may be formed by two-piece injection molding.

The double-material injection molding refers to that two different types of plastics are used, injection molding is carried out on the same injection molding machine, molding is carried out twice, and a product is only subjected to demolding once.
