Description

Technical Field

[0001] The present invention belongs to the technical field of clothing treatment equipment, and specifically relates to a washing drum assembly and a clothing treatment equipment. Background Art

[0002] Existing drum washing machines are mainly divided into front-opening drum washing machines and top-opening drum washing machines according to their structural types. Among them, the top-opening drum washing machine is popular among users because of its advantages such as small floor area and convenient access to clothes.

[0003] The clothing feeding port and the washing drum cover of the top-opening drum washing machine are arranged at the top of the washing drum, and there is a relatively large gap between the washing drum cover and the washing drum at the edge of the feeding port. During the process of washing clothes, the clothes may be thrown out of the washing drum through this gap or stuck in the gap, causing damage to the washing machine or the clothes.

[0004] Due to its special structure, the washing drum cover of the top-opening drum washing machine is a rotating part around an axis, which results in that the gap between the fixed part of the washing drum cover and the washing drum cover shaft, the cover frame, cannot be too small. The existing technology is to make this gap as small as possible on the premise of ensuring normal functions.

[0005] However, in this case, since the washing drum cover needs to ensure its rotating function, it cannot be tightly fitted in the left-right direction naturally. This will cause the washing drum cover to move slightly left and right. But the gap between the cover and the cover frame is already very small, and with the above-mentioned left-right movement, it may cause interference between the washing drum cover and the inner cylinder frame, resulting in the situation that the washing drum cover cannot be opened or closed, which seriously affects the user's operation experience.

[0006] Another situation is that the above-mentioned gap takes into account the left-right movement of the washing drum cover, which results in a relatively large gap. When the washing drum rotates at a high speed, under the action of centrifugal force, the clothes may drill out from this small gap between the cover and the cover frame, which may cause damage to the clothes.

[0007] In order to solve the above problems, in the Chinese patent with the patent publication number CN218492050U, a top-opening drum washing machine inner cylinder assembly is disclosed. In the inner cylinder body of the inner cylinder assembly, a first protective cover and a second protective cover are provided. The first protective cover and the second protective cover are respectively arranged on both sides of the feeding port. A first stop rib is provided on the first protective cover, and a second stop rib is provided on the second protective cover.

[0008] In the patent, the first stop rib and the second stop rib are provided. Although they can block the gaps on both sides of the inner cylinder cover, to prevent clothes from being thrown out of the gaps or getting stuck in the gaps, it is also necessary to press the inner cylinder cover against the corresponding stop ribs. This requires a high installation accuracy for the inner cylinder cover and the stop ribs. If there is an installation deviation, it is inevitable that there will be a gap between the inner cylinder cover and the stop rib, and there is still a possibility that clothes will drill out from this gap.

[0009] In view of this, the present invention is specifically proposed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a washing cylinder assembly that can not only effectively block the gaps on both sides of the washing cylinder cover, completely avoid clothes from being thrown out of the gaps or getting stuck in the gaps, but also reduce the requirement for installation accuracy.

[0011] Another technical problem to be solved by the present invention is to provide a laundry treatment device applying the washing cylinder assembly.

[0012] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0013] A washing cylinder assembly includes a washing cylinder and a washing cylinder cover assembly. Protective covers are provided on both sides of the feeding port of the washing cylinder. Corresponding to the protective covers, connecting ribs are respectively provided on both sides of the washing cylinder cover assembly and extend towards the protective covers. An extending portion is provided on the protective cover and a groove with an upward opening is formed on the extending portion. After the washing cylinder cover assembly is closed, the connecting ribs are inserted into the corresponding grooves to form a U-shaped labyrinth structure.

[0014] Further, the extending portion is bent upwards on the side away from the side wall of the protective cover, and together with the side wall of the protective cover, they enclose the groove, and the connecting ribs are vertically inserted into the corresponding grooves.

[0015] Further, the extending portion is recessed downwards to form the groove, and the connecting ribs are vertically inserted into the corresponding grooves.

[0016] Further, an upwardly protruding connecting portion is provided at the upper end of the side wall of the protective cover and extends away from the extending portion. The longitudinal section of the connecting portion is in an inverted L shape, its horizontal side extends away from the extending portion, and the top surface of the connecting portion is an arc surface.

[0017] Further, a receiving portion with one side bent is provided at the lower end of the protective cover, and the bent side of the receiving portion is connected to the connection between the extending portion and the side wall.

[0018] Further, the washing tub cover assembly includes a decorative member and a washing tub cover. The decorative member covers the upper part of the washing tub cover and is connected to the washing tub cover. Connecting ribs are provided on both sides of the decorative member and extend outwards.

[0019] Further, the decorative member includes a first decorative member and a second decorative member, which are respectively arranged on the upper and lower sides of the washing tub cover.

[0020] Further, the connecting ribs include a first connecting rib and a second connecting rib. The first connecting rib symmetrically extends downward from the first decorative member, and the second connecting rib symmetrically extends downward from the second decorative member. The first connecting rib and the second connecting rib on the same side are simultaneously inserted into the groove of the lower protective cover.

[0021] Further, the first connecting rib includes a first arc segment, a second arc segment, and a connecting arc segment. The connecting arc segment connects the first arc segment and the second arc segment, and the bending direction of the connecting arc segment is opposite to that of the first arc segment and the second arc segment.

[0022] The basic concept of another technical solution of the present invention is:

[0023] A laundry treatment device has the washing tub assembly as described above.

[0024] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0025] (1) By matching the groove structure provided on the protruding part of the protective cover with the corresponding connecting ribs on the washing tub cover assembly, a U-shaped labyrinth structure is formed at the connection, which can not only block the gaps on both sides of the washing tub cover, but also when the clothes are thrown out of the tub, they need to pass through a U-shaped channel. In this way, when they turn back, the direction is exactly opposite to the direction of the centrifugal force during dehydration, thus extending the ordinary gap into a U-shaped channel, which can completely prevent the clothes from being thrown out of this gap or stuck in the gap, avoiding the occurrence of clothes getting stuck, and effectively improving the user experience.

[0026] (2) By adopting a U-shaped labyrinth structure formed at the connection between the protruding part of the protective cover and the connecting ribs of the washing tub cover assembly, it is also beneficial to reduce the installation accuracy at the connection, making the structure simpler and the cost lower.

[0046] Embodiment 1

[0047] As Figure 1 shown, the present invention provides a washing tub assembly installed on a top-opening drum washing machine. The washing tub assembly includes a washing tub 1 and a washing tub cover assembly 5. A washing tub loading opening 2 is provided on the washing tub 1 for loading and unloading clothes. The washing tub cover assembly 5 is rotatably connected at the washing tub loading opening 2 and is turned upward to open, exposing the washing tub loading opening 2 for loading and unloading clothes. After being turned downward, the washing tub loading opening 2 is closed for washing.

[0048] In this embodiment, protective covers 3 are provided on both sides of the washing tub loading opening 2, namely a first protective cover 31 and a second protective cover 32. The first protective cover 31 and the second protective cover 32 are symmetrically arranged on both sides of the washing tub loading opening 2. Corresponding to the first protective cover 31 and the second protective cover 32, connecting ribs 4 extend from both sides of the washing tub cover assembly towards the first protective cover 31 and the second protective cover 32 respectively, and the connecting ribs 4 on both sides are also symmetrically arranged.

[0049] In this embodiment, the structures of the first protective cover 31 and the second protective cover 32 are exactly the same, and the structures of the connecting ribs 4 on the left and right sides are also exactly the same.

[0050] This embodiment will be described in detail taking the first protective cover 31 and the corresponding connecting rib 4 as examples.

[0051] In a further preferred embodiment of this embodiment, the first protective cover 31 has a side wall 315, and a protruding portion 311 is provided on the side wall 315 in a protruding manner. The protruding portion 311 is arranged below the corresponding connecting rib 4. A groove 312 with an upward opening is formed on the protruding portion 311. After the washing tub cover assembly 5 is closed, the connecting rib 4 is inserted into the corresponding groove 312 to form a U-shaped labyrinth structure.

[0052] In this embodiment, through the cooperation of the groove 312 structure provided on the protruding portion 311 and the corresponding connecting rib 4 provided on the washing tub cover assembly 5, a U-shaped labyrinth structure is formed at the connection, which can not only block the gaps on both sides of the washing tub cover, but also, when the clothes are thrown out of the tub, they need to go through a U-shaped channel. In this way, the direction when turning back is exactly opposite to the direction of the centrifugal force during dehydration, thereby extending an ordinary gap into a U-shaped labyrinth channel. This can completely prevent the clothes from being thrown out of this gap or getting stuck in the gap, avoiding the occurrence of clothes getting through, and effectively improving the user experience.

[0053] In a further preferred embodiment of this embodiment, the protruding portion 311 is bent upward on the side away from the side wall 315 of the protective cover 3, and together with the side wall 315 of the first protective cover 31, it encloses the groove 312. After the washing tub cover assembly 5 is closed, the connecting rib 4 is vertically inserted into the groove 312.

[0054] As Figure 4 shown, in this embodiment, a connecting portion 313 protruding upward is provided at the upper end of the side wall 315 of the first protective cover 31 in a direction away from the protruding portion 311. The longitudinal section of the connecting portion 313 is in an inverted L shape, consisting of a horizontal side and a vertical side. The vertical side is integral with the side wall 315 and is formed by extending downward integrally from the side wall 315. The horizontal side of the connecting portion 313 extends in a direction away from the protruding portion 311, and sealing plates 316 are also provided at the front and rear ends of the connecting portion 313. By providing the connecting portion 313, the connection between the protective cover 3 and the washing tub 1 is more stable. The inverted L setting makes the contact with the corresponding position of the washing tub 1 more stable, so that the protective cover 3 can be more reliably connected to the washing tub 1.

[0055] In a further preferred embodiment of this embodiment, the top surface of the connecting portion 313 is a downwardly convex arc surface. By setting the top surface of the connecting portion 313 as an arc surface, it fits better with the washing tub. The arc surface structure itself has uniform stress, improves strength and stability, can withstand a large torque, and has a long service life.

[0056] In this embodiment, a receiving portion 314 with a side bend is provided at the lower end of the side wall 315 of the first protective cover 31, and the bent side of the receiving portion 314 is connected to the connection between the protruding portion 311 and the side wall 315.

[0057] In a further preferred embodiment of this example, the receiving portion 314 is provided at the bottom of the protruding portion 311, which better supports the protruding portion 311 vertically. The lower end of the side wall 315 is connected to the receiving portion 314 to provide support for the side wall 315, improving the structural strength and stability.

[0058] In this embodiment, the washing tub 1 includes a washing tub body, and the washing tub body includes an annular wall 11. The washing tub opening 2 is provided on the annular wall 11. The first side wall 111 is on the left side of the washing tub opening 2, and the second side wall 112 is on the right side of the washing tub opening 2.

[0059] In this embodiment, the washing tub cover assembly 5 includes a decorative member 51 and a washing tub cover 52. The decorative member 51 covers the upper part of the washing tub cover 52 and is connected to the washing tub cover 52, and connecting ribs 4 are provided protruding on both sides of the decorative member 51.

[0060] As Figure 2 and Figure 3 shown, in this embodiment, the washing tub cover 52 includes a first washing tub cover 521 and a second washing tub cover 522.

The connecting end of the first washing tub cover 521 is rotatably connected to the washing tub body through a first rotating portion 523, and the connecting end of the second washing tub cover 522 is rotatably connected to the washing tub body through a second rotating portion 524. The first rotating portion 523 and the second rotating portion 524 are provided at opposite ends of the opening 2. The lower surface of the free end of the first washing tub cover 521 abuts against the upper surface of the free end of the second washing tub cover 522, and the free end of the first washing tub cover 521 presses on the free end of the second washing tub cover 522.

[0061] In a further preferred embodiment of this example, the first rotating portion 523 is fixedly connected to the front end of the washing tub opening 2, and the second rotating portion 524 is fixedly connected to the rear end of the washing tub opening 2.

[0062] In a further preferred embodiment of this example, when the first washing tub cover 521 is rotated, the second washing tub cover 522 can rotate synchronously with the first washing tub cover 521.

[0063] In this embodiment, the decorative member 51 includes a first decorative member 511 and a second decorative member 512. The first decorative member 511 and the second decorative member 512 are respectively provided on the upper and lower sides of the washing tub cover 52. The first decorative member 511 covers the first washing tub cover 521. The second decorative member 512 covers the second washing tub cover 522.

[0064] On the left and right sides of the first decorative member 511, first connecting ribs 41 symmetrically extend downward. On the left and right sides of the second decorative member 512, second connecting ribs 42 symmetrically extend downward. The first connecting ribs 41 and the second connecting ribs 42 on the same side are simultaneously inserted into the groove 312 of the lower first protective cover 31, and the first connecting ribs 41 and the second connecting ribs 42 on the other side are simultaneously inserted into the groove 312 of the lower second protective cover 32.

[0065] In a further preferred embodiment of the present embodiment, the first connecting rib 41 clamps both sides of the first washing tub cover 521 to prevent the first washing tub cover 521 from moving left and right and interfering, resulting in the first washing tub cover 521 not being able to be opened.

[0066] The second connecting rib 42 clamps both sides of the second washing tub cover 522 to prevent the second washing tub cover 522 from moving left and right and interfering, resulting in the second washing tub cover 522 not being able to be opened.

[0067] As Figure 4 、 Figure 5 and Figure 6 shown, in the present embodiment, the first connecting rib 41 and the second connecting rib 42 respectively extend vertically into the groove 312, and one end of the first connecting rib 41 extending into the groove 312 is bent.

[0068] In the present embodiment, the first connecting rib 41 includes a first arc segment 411, a connecting arc segment 412, and a second arc segment 413. The radian of the first arc segment 411 is greater than the radian of the second arc segment 413.

[0069] In a further preferred embodiment of the present embodiment, the first arc segment 411 and the second arc segment 413 cooperate with the protective cover 3, greatly reducing the occurrence of clothes drilling out from the gap of the washing tub.

[0070] In a further preferred embodiment of the present embodiment, the bottom surface of the groove 312 is provided with a curved surface structure.

[0071] In a further preferred embodiment of the present embodiment, the bottom surface of the groove 312 is provided with a first curved surface 3111 and a second curved surface 3113, and a connecting curved surface 3112 connects the first curved surface 3111 and the second curved surface 3113. The first curved surface 3111 cooperates with the first arc segment 411, and the second curved surface 3113 and the second arc segment 413 cooperate.

[0072] In a further preferred embodiment of the present embodiment, the second curved surface 3113 is connected with a third curved surface 3114. The bending direction of the third curved surface 3114 is opposite to that of the second curved surface 3113 to prevent the first connecting rib 41 from moving around.

[0073] In a further preferred embodiment of the present embodiment, the connecting rib 4 at the edge of the decorative member 51 exactly falls into the groove 312 of the first protective cover 31 and the second protective cover 32, forming a U-shaped labyrinth structure. When the clothes are thrown out of the washing tub, they need to pass through a U-shaped channel.

[0074] In a further preferred embodiment of the present embodiment, after the washing tub cover is closed, the first connecting rib 41, the second connecting rib 42 and the groove 312 form a U-shaped structure. When the clothes are thrown out of the washing tub, they need to pass through a U-shaped channel. In this way, the direction when folding back is exactly opposite to the direction of the centrifugal force during dehydration, thereby extending an ordinary gap into a U-shaped channel.

[0075] Embodiment 2

[0076] The difference from Embodiment 1 is that in this embodiment, the protruding portion 311 is recessed downward to form a groove 312, and the first connecting rib 41 and the second connecting rib 42 are vertically inserted into the corresponding grooves 312.

[0077] In a further preferred embodiment of the present embodiment, after the protruding portion 311 extends horizontally, a groove 312 is recessed downward on the protruding portion 311, and the cross-section of the groove 312 is set to be U-shaped.
