Description

Technical Field

[0001] The present invention belongs to the field of clothing processing equipment, and in particular, relates to a supporting assembly and clothing processing equipment having the supporting assembly. Background Art

[0002] The drum dryer is equipped with a drum for loading clothes. Since clothes need to be put into the drum, the drum is designed to be open at one end (or both ends). In order to ensure that the clothes being dried can be dried evenly and quickly, the drum is rotated by a motor via a belt drive. When the drum rotates, its open end cannot be connected to the body of the drum through the shaft structure of the drum axis, so a freely rotatable roller is required to effectively support the open end of the drum.

[0003] In the existing field of drum dryers, the manufacturing and assembly methods of the drum support wheel can be divided into two categories: the first category is the integral insert injection molding of the rolling bearing (standard part) and the drum hub, and the insert injection-molded hub assembly is then insert-molded a second time with the outer ring tire (semi-hard material); the second category is the pre-assembly of the rolling bearing (standard part) with two sheet metal hub parts (the two sheet metal hub parts sandwich the roller in the middle), and then fixed by TOX riveting or spot welding, and then the assembled sheet metal hub assembly is insert-molded with the outer ring tire (semi-hard material).

[0004] At present, most support assemblies are composed of each roller support wheel that is in rolling contact with the roller. When the roller moves eccentrically, the support stability of the support assembly is poor. Therefore, designing a support assembly that can quickly restore stable support when the roller bounces has become a problem that needs to be solved urgently.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a support assembly and a clothing processing device having the support assembly. A plurality of second support members contact and support an object to support the object on the support assembly. The first support member is spaced apart from the object. When the object is subjected to a large force and moves in the direction of the support assembly, in addition to the second support members supporting the object, the first support member contacts the object to achieve compensatory support for the object, thereby making the support of the object by the support assembly more stable.

[0016] Preferably, there is one first support member and two second support members, and the two second support members are symmetrical about a straight line passing through the first support member and the center of the circle.

[0017] A clothing processing device having the above-mentioned support assembly includes a drum assembly, the support assembly is used to support the drum assembly, a second support member is in contact with and supports the drum assembly, and a first support member is spaced a certain distance from the drum assembly, and the first support member is in contact with and supports the drum assembly when the drum assembly moves eccentrically.

[0018] The first support member is a supporting roller, and the second support member is a positioning roller, the positioning roller is in rolling contact with the side wall of the roller assembly, the supporting roller is spaced a certain distance from the side wall of the roller assembly, and the supporting roller is in rolling contact with the side wall of the roller assembly when the roller assembly moves eccentrically;

[0019] Preferably, the positioning rollers are arranged on both sides of the supporting roller.

[0020] The distance between the first support member and the side wall of the roller assembly is not greater than the maximum eccentric distance of the roller assembly;

[0021] Preferably, the distance between the outer peripheral wall of the support roller and the side wall of the drum assembly is 0.5-5 mm;

[0022] More preferably, the distance between the outer peripheral wall of the supporting roller and the side wall of the drum assembly is 1 mm.

[0023] The supporting roller is opposite to the lowest point of the roller assembly, and the positioning rollers on both sides of the supporting roller are symmetrical about a straight line passing through the center of the supporting roller and the center of the roller assembly;

When the object is subjected to a large force and moves in the direction of the support assembly, in addition to the second support member supporting the object, the first support member contacts the object to achieve compensatory support for the object, making the support of the object by the support assembly more stable;

[0031] 2.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the 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.

[0040] Embodiment 1

[0041] like Figure 1-3 As shown, a support assembly is used to support an object. The support assembly includes a support frame 100 and a first support member 101 and a plurality of second support members 102 arranged on the support frame 100. The plurality of second support members 102 are in contact with and support the object, and the first support member 101 is spaced apart from the object.

[0042] The first support member 101 and multiple second support members 102 are all arranged on the support frame 100, wherein the multiple second support members 102 are in contact with and support the object, and can support the object on the support assembly. When the object is subjected to a large force and moves toward the support assembly, in addition to the support of the object by the second support members, at this time, the first support member 101 is in contact with the object to achieve compensatory support for the object, so that the support of the object by the support assembly is more stable.

[0043] Furthermore, the first support member 101 and / or the second support member 102 is a rolling member rotatably arranged on the support frame 100, a plurality of the second support members 102 are tangent to the same circumference, and the first support member 101 is located outside the circumference.

[0044] The second support member 102 is a rolling member, so that the contact support between the object and the second support member 102 is rolling contact, which has smaller friction and better stability. The contact support between the first support member 101 and the object is the same as the above principle.

[0045] Multiple second support members 102 are tangent to the same circle, and the first support member 101 is located outside the circle, forming inner and outer layers of support on the support assembly. When the object vibrates or bounces violently, in addition to the second support member, the first support member contacts the object to provide compensating support force for the object, making it easier to balance the object.

[0046] The plurality of second support members 102 are in contact with the object for support, thus playing a role of positioning support and being more stable.

[0047] Solution 1: both the first support member 101 and the second support member 102 are rollers, the outer side walls of the second support members 102 are tangent to the same circumference, and the first support member 101 is located outside the circumference. Specifically, the roller is connected to the support frame 100 by bolts, and the circular side wall of the roller contacts and supports the object.

[0048] Solution 2: Both the first support member 101 and the second support member 102 are balls, the outer peripheral walls of the plurality of second support members 102 are tangent to the same circumference, and the first support member 101 is located outside the circumference. Specifically, a groove is provided on the support frame 100, and the balls are arranged in the groove, the upper ends of the balls protrude from the notches of the groove, and the objects are contacted and supported by the outer peripheral walls of the balls.

[0049] Furthermore, the second support members 102 are arranged on both sides of the first support member 101. The second support members 102 on both sides contact and support the object, forming support points on both sides of the first support member 101, so that the positioning of the object is more accurate, and the object is easier to balance, so that the support assembly supports the object more stably. The first support member 101 is located in the middle of the second support member 102, and the compensatory support of the first support member 101 to the object is more evenly distributed on the second support members on both sides, so that the object is easier to balance.

[0050] In solution 1, there are multiple second support members 102 and one first support member 101 , and the multiple second support members 102 are disposed on both sides of the first support member 101 .

[0051] In solution 2, there are multiple first support members 101 and multiple second support members 102 , and at least one first support member 101 is disposed between any two adjacent second support members 102 .

[0052] In a further solution, the plurality of second support members 102 are symmetrical with respect to the first support member 101 , and this structure makes the object more stable on the support assembly.

[0053] For example, there is one first support member 101 and two second support members 102, and the two second support members 102 are symmetrical about the line connecting the first support member 101 and the center of the circle, that is, the first support member 101 and the two second support members 102 are arranged in an isosceles triangle on the support frame, and the distance from the first support member 101 to the second support member 102 on the left is equal to the distance from the first support member 101 to the second support member 102 on the right, so that the compensating support force generated by the first support member 101 is evenly distributed on the second support members 102 on both sides, making the object easier to balance.

[0054] Embodiment 2

[0055] like Figure 1-3 As shown, this embodiment is a clothing processing device provided with the support assembly of embodiment 1, including a drum assembly 104, the support assembly is used to support the drum assembly 104, the second support member 102 is in contact with and supports the drum assembly 104, the first support member 101 is spaced a certain distance from the drum assembly 104, and the first support member 101 is in contact with and supports the drum assembly 104 when the drum assembly 104 moves eccentrically.

[0056] When the drum assembly 104 rotates, the second support member 102 contacts and supports the drum assembly 104, thereby supporting the drum assembly 104. However, if the clothes therein are unevenly distributed, the drum assembly 104 may easily undergo eccentric movement when rotating, causing the drum assembly 104 to jump and deviate from the original movement trajectory. By providing the first support member 101, the drum assembly 104 is in contact and supported when it moves eccentrically, thereby providing compensatory support for the drum assembly 104, allowing the drum assembly 104 to return to its original running trajectory, thereby improving the stability of the support member in supporting the drum assembly 104 and reducing damage.

[0057] Furthermore, the first support member 101 is a support roller 101, and the second support member 102 is a positioning roller 102, the positioning roller 102 is in rolling contact with the side wall of the roller assembly 104, the support roller 101 is spaced a certain distance from the side wall of the roller assembly 104, and the support roller 101 is in rolling contact with the roller assembly 104 when it moves eccentrically.

[0058] Specifically, there are two positioning rollers 102 and one supporting roller 101. The two positioning rollers 102 are arranged on both sides of the supporting roller 101. The positioning rollers 102 are in rolling contact with the side walls of the roller assembly 104. The supporting roller 101 is spaced a certain distance from the side walls of the roller assembly 104. The supporting roller 101 is in rolling contact with the roller assembly 104 when it moves eccentrically.

[0059] Since the roller is in a rotating state during operation, the support assembly is provided with a support roller 101 and a positioning roller 102. When the positioning roller 102 rolls in contact with the roller assembly 104, the friction resistance is reduced, and the obstruction of the positioning roller 102 to the rotating roller assembly 104 is reduced. At this time, the support roller 101 is not in contact with the roller assembly 104. When the roller assembly 104 moves eccentrically, the support roller 101 rolls in contact with the roller assembly 104, providing compensatory support for the roller assembly 104, making it easier for the roller assembly to return to contact with the positioning roller 102, and making the support more stable.

[0060] Further, the distance between the first support member 101 and the side wall of the roller assembly 104 is not greater than the maximum eccentric distance of the roller assembly 104. If the distance between the first support member 101 and the side wall of the roller assembly 104 is too large, even if the roller assembly 104 is eccentric, the first support member 101 still cannot support it. If the distance between the first support member 101 and the side wall of the roller assembly 104 is too small, a slight eccentricity will be compensated for, and the compensation is too frequent, which affects its service life. Therefore, by controlling the distance between the first support member 101 and the side wall of the roller assembly 104, a better compensation support effect is achieved.

[0061] Wherein, the distance between the outer peripheral wall of the supporting roller and the side wall of the roller assembly is 0.5-5mm;

[0062] Preferably, the distance between the outer peripheral wall of the supporting roller and the side wall of the drum assembly is 1 mm.

[0063] Furthermore, the support roller 101 is opposite to the lowest point of the roller assembly, and the positioning rollers 102 on both sides of the support roller are symmetrical about a straight line passing through the center of the support roller 101 and the center of the roller assembly 104 .

[0064] Specifically, there are two positioning rollers 102, which are disposed on both sides of the supporting roller and are symmetrical about a straight line passing through the center of the supporting roller and the center of the drum assembly, so that the two positioning rollers 102 are located at the same vertical height.

[0065] Furthermore, the support frame 100 has an arc-shaped notch 103, the roller assembly 104 is arranged in the arc-shaped notch 103 of the support frame 100, the support roller 101 and the positioning roller 102 are arranged along the edge of the arc-shaped notch 103, the second support member 102 is in contact with and supported by the outer wall of the roller assembly 104, and the first support member 101 is spaced a certain distance from the outer wall of the roller assembly 104.

[0066] The arc-shaped notch 103 is provided to facilitate the accommodation of the roller assembly 104 , and to facilitate the provision of the supporting roller 101 and the positioning roller 102 , and to arrange them along the edge of the arc-shaped notch 103 .

[0067] Preferably, the supporting roller 101 is arranged in the middle of the arc-shaped notch 103 , and the positioning rollers 102 are arranged at both ends of the arc-shaped notch 103 .

[0068] Further, the support assembly is disposed at the lower portion of the drum assembly 104 .

[0069] Preferably, the support assembly is disposed at the lower portion in front of the drum assembly 104.

[0070] Since the rear of the roller assembly 104 is connected to the output shaft of the driving device to drive the roller assembly 104 to rotate, and the front end is suspended, the support assembly is arranged at the lower part in front of the roller assembly 104 to make the support more stable.

[0071] Furthermore, the support frame 100 has a buffer support portion for buffering the impact force of the roller assembly 104 on the first support member 101 .

[0072] Preferably, the support frame 100 includes a main body and a triangular bracket, the triangular bracket and the main body are integrally formed to form a buffer support portion, and the first support member 101 is arranged at the vertex position of the triangular bracket.

[0073] The laundry processing appliance includes a twin washing machine, a drum washing machine or a clothes dryer.

[0074] Embodiment 3

[0075] like Figure 1-3 As shown, this embodiment is a specific solution of the second embodiment, a washer-dryer, comprising a housing 105 and a drum assembly 104 and a support assembly arranged in the housing 105, the rear of the drum assembly 104 is connected to a driving device for driving the drum assembly 104 to rotate, and the front is suspended. A support assembly is arranged at the bottom of the drum assembly 104 to make the drum assembly 104 more stable during rotation.

[0076] The support assembly is arranged in front of the lower part of the roller assembly 104. When the roller assembly 104 is eccentric, the eccentric distance at this position is the largest. Arranging the support assembly at this position makes it easier to balance the roller assembly 104.

[0077] The support assembly includes a support frame 100, two positioning rollers 102 and a supporting roller 101, and the positioning roller 102 and the supporting roller 101 are rotatably arranged on the support frame 100. The rotation axes of the positioning roller 102, the supporting roller 101 and the roller assembly 104 are parallel to each other, and the positioning roller 102, the supporting roller 101 and the roller assembly 104 are located in the same plane.

[0078] An arc-shaped notch 103 opening upward is provided on the upper portion of the support frame 100 . Two positioning rollers 102 and one supporting roller 101 are distributed along the arc-shaped edge of the arc-shaped notch 103 . Both the two positioning rollers 102 and one supporting roller 101 protrude from the edge of the arc-shaped notch 103 .

[0079] The supporting roller 101 is arranged in the middle of the arc-shaped notch 103 and is opposite to the lowest point of the roller assembly 104. The two positioning rollers 102 are arranged at both ends of the arc-shaped notch 103. The two positioning rollers 102 are bilaterally symmetrical about a straight line passing through the center of the supporting roller 101 and the center of the roller assembly 104. That is, the two positioning rollers 102 are on the same circumference and are located at the same vertical height. The two positioning rollers 102 are located at the same vertical height. The two positioning rollers 102 are lower than the center of the roller assembly 104.

[0080] The roller assembly 104 is arranged on the inner side of the arc-shaped notch 103. When the roller assembly 104 is placed on the arc-shaped notch 103 of the supporting assembly, the positioning roller 102 contacts and supports the outer wall of the roller assembly 104. At the same time, the supporting roller 101 is spaced a certain distance from the roller assembly 104. When the roller assembly moves eccentrically, the supporting roller 101 contacts and supports the roller assembly 104.

[0081] The distance L between the outer peripheral wall of the supporting roller and the side wall of the drum assembly is 1 mm.

[0082] Both sides of the support assembly are connected to the inner wall of the box body by screws, so that the support assembly is fixed in the box body 105 .
