As shown in fig. 1 to 10, according to an embodiment of the present utility model, there is provided a connection pad 34 for a laundry treating apparatus 100, wherein, as shown in fig. 7, a concave structure 342, a convex structure 341, and a connection structure 343 are respectively provided on the connection pad 34, the concave structure 342 and the convex structure 341 are both of a frustum structure, the connection structure 343 is provided at a distance from the convex structure 341, the concave structure 342 is provided on the convex structure 341, and a concave direction of the concave structure 342 is provided opposite to a convex direction of the convex structure 341.

Specifically, when the connection pad 34 is used for the laundry treating apparatus 100, the connection pad 34 is mounted at the bottom of the inner tub 32 of the laundry treating apparatus 100 and is fixedly connected to the bottom of the inner tub 32 by a connection structure 343, and the connection-fixed connection pad 34 closes the bottom opening 322 of the inner tub 32. Wherein the protruding structure 341 on the connection pad 34 extends to the inside of the inner tub 32 through the bottom opening 322 of the inner tub 32, the recess structure 342 is concavely provided to one side of the bottom opening 322, and the clutch of the driving mechanism 33 of the laundry treating apparatus 100 is coupled to the recess structure 342.

When the dehydrating operation is performed, the driving mechanism 33 drives the inner tub 32 to rotate at a high speed through the connection pad 34, and the dehydrating operation is performed on the laundry in the inner tub 32 by the centrifugal force. The protruding structures 341 and the recessed structures 342 are arranged on the connecting disc 34, and the protruding structures 341 and the recessed structures 342 are arranged in opposite directions, so that compared with the existing connecting disc 34 in a flat plate shape, the strength is increased, the possibility of deformation in the use process is reduced, and the problem that the inner barrel 32 and the outer barrel 31 collide due to deformation of the connecting disc 34 is effectively solved.

In addition, by arranging the protruding structures 341 and the recessed structures 342 on the connecting disc 34, compared with the prior art, the overall rigidity of the connecting disc 34 can be greatly improved on the premise of not increasing the thickness of the connecting disc 34, the deformation resistance of the connecting disc 34 is improved, and the quality of the connecting disc 34 and the manufacturing cost can be effectively reduced.

It should be understood that when the inner tub 32 is used to dehydrate laundry, it is often the case that the center of gravity of the inner tub 32 is deviated from the axis of the inner tub 32 due to the difference of the arrangement positions of the laundry in the inner tub 32, and at this time, the inner tub 32 is eccentrically rotated when the inner tub 32 is driven to rotate, and the connection disc 34 is deformed if the strength of the connection disc 34 is low.

In the embodiment of the utility model, as shown in fig. 7, the land 34 is a plate-like member, the convex structure 341 is provided on the plate-like member, and the concave structure 342 is provided on the convex structure 341. After the connecting disc 34 is installed and fixed on the inner barrel 32, the protruding structure 341, the concave structure 342 and the inner barrel 32 are coaxially arranged, and after the clutch is connected with the concave structure 342, the rotating shaft of the clutch is coaxially arranged with the concave structure 342. The concave structure 342 and the convex structure 341 are both frustum structures, and the convex direction of the convex structure 341 and the concave direction of the concave structure 342 are set to be opposite, so that the connecting disc 34 is provided with a concave-convex shape, the connecting disc 34 with the concave-convex shape is compared with the connecting disc 34 with a platy structure, the structure is complex, and the overall strength is high, therefore, the clutch is connected to the concave structure 342, the strength of the connection position is enhanced, the possibility that the connecting disc 34 deforms in the clutch driving process is reduced, the eccentric motion of the inner barrel 32 in the rotating process is relieved, and the possibility that the inner barrel 32 collides with the outer barrel 31 is reduced.

In addition, the connection pad 34 is mounted at the bottom of the inner tub 32 of the laundry treating apparatus 100 and is fixedly connected with the bottom of the inner tub 32 by a connection structure 343, a protrusion structure 341 on the connection pad 34 extends to the inside of the inner tub 32 through a bottom opening 322 of the inner tub 32, and a recess structure 342 is provided at the top of the protrusion structure 341 for connection with a clutch of the driving mechanism 33 of the laundry treating apparatus 100. The concave structure 342 is arranged towards one side of the bottom opening 322 in a concave mode, namely, the directions of the concave structure 342 and the convex structure 341 are opposite, so that the mounting requirement of a clutch is met, the position and the structure of the clutch are not required to be improved, the overall cost is reduced, and the purpose of improving the impact between the inner barrel 32 and the outer barrel 31 caused by the deformation of the connecting disc 34 under the condition of low cost is achieved.

It should be noted that, the connection pad 34, the protruding structure 341 and the recessed structure 342 may be an integral structure or a split structure, where when the three are integral structures, the three are manufactured by adopting an integral processing method, and when the three are split structures, the three are manufactured by adopting a split processing method, and then the three are connected and fixed by welding or bonding.

In the embodiment of the present utility model, the connection pad 34, the protruding structure 341 and the recessed structure 342 are integrated, that is, the protruding structure 341 and the recessed structure 342 are machined on the connection pad 34, wherein the machining mode may be casting, 3D printing or stamping. As a specific embodiment, the connecting disc 34 is a sheet metal part, the protruding structure 341 and the recessed structure 342 are formed on the connecting disc 34 in a punching manner, and the protruding structure 341 and the recessed structure 342 are processed in a punching manner, so that the structural consistency among the protruding structure 341, the recessed structure 342 and the connecting disc 34 is further improved, and meanwhile, the structural strength is ensured to be stable, so that the overall rigidity of the connecting disc 34 is enhanced.

In addition, the transition position between the protruding structure 341 and the connecting disc 34 has the first round chamfer, and by providing the first round chamfer, the condition that stress concentration occurs at the transition position between the protruding structure 341 and the connecting disc 34 can be reduced, so that the structural strength of the connecting disc 34 is further improved. Meanwhile, the transition positions of the concave structures 342 and the convex structures 341 are provided with second round chamfers, and the situation that stress concentration occurs at the transition positions of the concave structures 342 and the convex structures 341 can be reduced through the second round chamfers, so that the structural strength of the connecting disc 34 can be further improved.

In addition, as shown in fig. 10, when the connection pad 34 is connected to the inner tub 32, the boss structure 341 having a truncated cone structure is coaxially disposed with the bottom opening 322 of the inner tub 32, the boss structure 341 is coaxially inserted into the bottom opening 322, the bottom opening 322 is closed by the boss structure 341, and the connection pad is abutted against the bottom surface of the inner tub 32 and is connected to the inner tub 32 by the connection structure 343.

It is further understood that, as shown in fig. 2, 3 and 10, when the coupling disc 34 is used for the laundry treating apparatus 100, the coupling disc 34 is mounted and fixed to the bottom of the inner tub 32 and the bottom opening 322 of the inner tub 32 is closed, and the coupling of the driving mechanism 33 is coupled to the coupling disc 34, and the coupling disc 34 rotates the inner tub 32 under the driving of the coupling, so that the laundry in the inner tub 32 is dehydrated.

During the rotation of the inner tub 32, the inner tub 32 has an axis of rotation, and the protrusion structure 341 is protruded to one side (toward the inside of the inner tub 32 through the bottom opening 322 of the inner tub 32) and the recess structure 342 is recessed to the other side (opposite to the protrusion direction of the protrusion structure 341) in the axis direction of the inner tub 32. As shown in fig. 7 or 10, wherein the bump height of the bump structure 341 in the axial direction of the inner tub 32 (the distance between the lowest position of the land 34 and the highest position of the bump structure 341) is H1, and the recess height of the recess structure 342 in the axial direction of the inner tub 32 (the distance between the lowest position of the land 34 and the lowest position of the recess structure 342) is H2, wherein H2 < H1.

Specifically, the protrusion structure 341 and the recess structure 342 are both located at the same side of the connection pad 34, the protrusion structure 341 is formed on the connection pad 34 and is a frustum structure having a large end and a small end, wherein the large end of the protrusion structure 341 is connected to the connection pad 34, the small end of the protrusion structure 341 extends into the inner tub 32 through the bottom opening 322 of the inner tub 32, and the recess structure 342 is disposed on the small end of the protrusion structure 341. The concave structure 342 is also a frustum structure and has a large end and a small end, wherein the large end of the concave structure 342 is connected with the small end of the convex structure 341, the small end of the concave structure 342 is concavely arranged, the integral strength of the connecting disc 34 is enhanced by utilizing the composite modeling formed by the convex structure 341 and the concave structure 342, and the convex height of the convex structure 341 is set to be larger than the concave height of the concave position, so that the strength of the composite structure formed by the concave structure 342 and the convex structure 341 is further enhanced, and the integral strength of the connecting disc 34 is further improved.

It should be understood that the bump structure 341 is a frustum structure, and has a large end and a small end, where the large end and the small end are both planes, the large end face and the small end face are arranged at parallel intervals, the large end face is arranged flush with the lowest position of the connecting disc 34, and the distance between the large end face and the small end face is the bump height of the bump structure 341.

In addition, the concave structure 342 of the frustum structure also has a large end and a small end, wherein the large end and the small end are both planes, the large end face and the small end face are arranged at parallel intervals, the large end face of the concave structure 342 and the small end face of the convex structure 341 are flush, and the vertical distance between the small end face of the concave structure 342 and the large end face of the convex structure 341 is the concave height.

Note that h2+m=h1, M is the height difference between H2 and H1, and the value interval of M is [5mm,30mm ], where the value of M may be 5mm, 8mm, 11mm, 14mm, 17mm, 20mm, 23mm, 26mm … … mm.

In addition, the protruding structure 341 and the recessed structure 342 are both located at the same side of the connection pad 34, and when the clutch of the driving mechanism 33 is fixedly connected with the recessed structure 342, by providing the height difference M, a part of the structure of the clutch can be extended into the inner tub 32, so that the size of the inner tub 32 in the axial direction thereof can be increased, and further the volume of the inner tub 32 is increased, so that the receiving capacity of the laundry treating apparatus 100 for laundry is enhanced.

Further, as shown in fig. 7, the bump height (distance between the lowest position of the land 34 and the highest position of the bump structure 341) of the bump structure 341 in the axial direction of the inner tub 32 is H1, the thickness of the land 34 in the axial direction of the inner tub 32 is T, wherein H1 is greater than 0, and H1 is less than 15T.

In the embodiment of the present utility model, the protruding structures 341 and the recessed structures 342 are formed on the land 34 by punching, and the land 34 has a certain thickness, which is T, before the work, and each position of the recessed structures 342 and each position of the protruding structures 341 are identical to the thickness of the land 34 after the protruding structures 341 and the recessed structures 342 are formed by punching. By controlling the height H1 of the bump structure 341 (the distance between the lowest position of the land 34 and the highest position of the bump structure 341), the situation that the bump is too high to cause thinning of the material or even punching and tearing is prevented on the basis of increasing the strength of the whole structure of the land 34, and the yield of the product is ensured.

It should be understood that setting H1 to be greater than 0 ensures that the bump structure 341 can be formed, and when the bump height is greater than 1.5T, the average thickness of the bump structure 341 may be thinned, failing to ensure the strength of the bump structure 341, resulting in failing to ensure the overall strength of the land 34.

It should be noted that, in the present utility model, the value of H1 may be 1T, 3T, 5T, 0.7T, 9T, 11T, 13T … … T.

Further, as shown in fig. 2, 4, 5 or 9, in the embodiment of the present utility model, the land 34 is provided in a square structure, the land 34 of the square structure has a middle area, wherein the convex structure 341 is formed in the middle area of the square structure, and the center of the convex structure 341 is disposed to coincide with the center of the square structure.

Specifically, the bump structure 341 is in a frustum structure, a large end of the frustum structure is connected to the connecting disc 34, a projection formed by the frustum structure on the connecting disc 34 is located in an area of the connecting disc 34, taking a square structure as an example, if a diameter of a large end face is consistent with a side length of the square structure, the large end face is inscribed on each side of the square structure, as shown in fig. 4, by setting a minimum distance between the bump structure 341 and an edge of the square structure to be a, a is greater than 0mm and less than or equal to 5mm, and the connecting disc 34 is ensured to be smoothly processed and molded while a large enough area of the bump structure 341 is ensured on the connecting disc 34.

It should be understood that, when the minimum distance a between the edge of the square structure and the protruding structure 341 is equal to 0, the large end face of the protruding structure 341 is inscribed on the connecting disc 34 with the square structure, and in the processing process, due to the limitation of the processing conditions, a certain structure needs to be reserved at the inscribed position, so when the minimum distance a between the edge of the square structure and the protruding structure 341 is equal to 0, the processing difficulty is increased, which is not beneficial to the improvement of the production efficiency of the product.

When the minimum distance a between the bump structure 341 and the edge of the square structure is greater than 5mm, the distance between the bump structure 341 and the edge of the square structure is too large, and at this time, the ability of the bump structure 341 to enhance the overall strength of the land 34 is reduced, which is disadvantageous to the increase of the overall strength of the land 34.

In addition, as the value of a is smaller, the raised structure 341 is more capable of enhancing the overall strength of the land 34, but the difficulty of processing is greater. On the contrary, when the value of a is larger, the difficulty of processing is at the end of the month, and the capability of the bump structure 341 for enhancing the overall strength of the land 34 is poorer.

It should be noted that, as shown in fig. 4, the minimum distance between the protruding structure 341 and the edge of the square structure is a, where a may have a value of 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm … … mm.

Further, when the coupling disc 34 is used for the laundry treating apparatus 100, the coupling disc 34 is installed at the bottom of the inner tub 32 and closes the bottom opening 322 of the inner tub 32, and is fixedly coupled to the bottom surface of the inner tub 32 by the coupling structure 343, and when the inner tub 32 rotates, the coupling disc 34 corrects the inner tub 32, which is eccentrically rotated, to eliminate the eccentric rotation.

As shown in fig. 2 and 4, the inner bottom surface of the inner tub 32 has a circular structure, the connection pad 34 has a square structure, the center of the square structure (the intersection of diagonal lines) coincides with the center of the inner tub 32 (the position where the rotation axis of the inner tub 32 passes), the length of the diagonal line of the square structure is defined as L, and the diameter of the bottom surface of the inner tub 32 is defined as D, wherein L is equal to or greater than D/2 and equal to or less than D.

By setting L and D, the bottom surfaces of the connecting disc 34 and the inner barrel 32 have enough contact areas to ensure the overall strength of the connecting disc 34 and the inner barrel 32 after connection and fixation, further reducing the eccentric rotation of the inner barrel 32 and reducing the collision of the inner barrel 32 with the outer barrel 31.

It is to be understood that when L is greater than D, a portion of the structure of the connection pad 34 is disposed beyond the inner bottom surface of the inner tub 32, and the excess structure is liable to adversely affect other parts, such as scratch or interfere with the other parts, during rotation. When L is smaller than D/2, the contact area between the connection pad 34 and the inner tub 32 is too small, and when the inner tub 32 eccentrically rotates, the force acting on the connection pad 34 by the inner tub 32 is large, which easily causes deformation of the connection pad 34, and thus the inner tub 32 cannot be effectively prevented from colliding with the outer tub 31.

In addition, in the embodiment of the present utility model, the larger the value of L, the more the correction capability of the land 34 for the inner tub 32 in which the eccentric rotation occurs, whereas the smaller the value of L, the worse the correction capability of the land 34 for the inner tub 32 in which the eccentric rotation occurs.
