Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The laundry treating apparatus 100 according to the embodiment of the present invention will be described with reference to fig. 1 to 5, and the laundry treating apparatus 100 may be a clothes dryer or other washing apparatus provided with a drum 1, and the type of the laundry treating apparatus 100 is not particularly limited herein.

The laundry treating apparatus 100 according to an embodiment of the present invention, as shown in fig. 1 and 2, includes: a drum 1, a peripheral body unit 2 and a support assembly 3.

The drum 1 has a cylindrical shape, a front side of the drum 1 is opened to form a throat 10, and a peripheral body unit 2 is provided at the front side of the drum 1. The supporting component 3 comprises a wheel shaft 31 and a roller 32, the wheel shaft 31 is located on the outer side of the roller 1, the front end of the wheel shaft 31 is connected to the peripheral machine body part 2, the rear end of the wheel shaft 31 is suspended, the roller 32 is rotatably sleeved on the wheel shaft 31 in a sleeved mode, the roller 32 is in contact with the outer peripheral wall of the roller 1 to support the roller 1 to rotate, and the supporting component 3 is supported at the front end of the roller 1. Wherein the roller 32 is in contact with the maximum diameter of the drum 1.

Here, parts of the laundry treating apparatus 100 located at the front side of the drum 1 may be mounted on the peripheral body part 2, and for example, a door body of the laundry treating apparatus 100 may be provided on the peripheral body part 2. In fig. 1, a baffle 21 is provided on a rear surface of the peripheral body unit 2, the peripheral body unit 2 is stopped in front of the drum 1 and the baffle 21 of the peripheral body unit 2 is stopped at a side surface of the drum 1, thereby limiting a movable range of the drum 1 and preventing the drum 1 from shaking, etc.

It should be noted that, in a general clothes dryer, if the roller is supported at the front end of the drum, the front end of the drum is usually designed with a closing structure, that is, the diameter of the drum at the mouth of the drum is reduced to form a closing, and the roller is supported at the closing structure. At this moment, because the diameter of gyro wheel and cylinder is less to be cooperateed, the terminal surface of gyro wheel easily wipes the cylinder body, consequently just needs to enlarge the axial dimension of binding off structure, leads to the size reduction of cylinder body, and the cylinder volume reduces.

Moreover, it can be understood that if the outer contour of the closing-in at the contact part with the roller cannot be processed into a circle, the roller can shake up and down, left and right when rotating along the roller. Therefore, when the roller is used for processing the closed end, the size of the roller needs to be reduced, the roller needs to be processed into a round shape, and the processing difficulty is high.

In the embodiment of the invention, the roller 32 is contacted with the position with the largest diameter of the roller 1, the end surface of the roller 32 is not contacted with the roller 1, and the roller 1 does not interfere with the roller 32. Therefore, the axial size of the drum body of the drum 1 is increased, and the volume of the drum 1 is increased. And the outline of the maximum diameter position of the roller 1 is ensured to be formed into a circle, the processing difficulty of the roller 1 can be properly reduced, the matching effect of the roller 32 and the roller 1 is better, and the operation is more stable.

According to the clothes treatment device 100 of the embodiment of the invention, the roller 32 in the supporting component 3 of the roller 1 is contacted with the position with the largest diameter of the roller 1, so that the capacity of the roller 1 is favorably improved, the matching effect of the roller 32 and the roller 1 is better, and the operation is more stable.

In some embodiments, there is a line contact fit between the roller 32 and the drum 1. Specifically, the axial section of the roller 32 is a plane, and the contact between the roller 32 and the roller 1 is a line contact, so that the contact part between the roller 32 and the roller 1 is long, and the matching operation is stable.

Specifically, the axle 31 is disposed parallel to the central axis of the drum 1, so that the central axis of rotation of the roller 32 is parallel to the central axis of rotation of the drum 1, which is beneficial to make the roller 32 and the drum 1 operate more stably in a matching manner.

In some embodiments, the number of the supporting components 3 is multiple, the wheel shaft 31 in each supporting component 3 is connected with the peripheral body part 2, and the roller 32 in each supporting component 3 is in contact with the outer peripheral wall of the roller 1, so that the multiple supporting components 3 form multi-point support for the roller 1 on the outer periphery of the roller 1, which is beneficial to the running stability of the roller 1, and the limit of the multiple roller 32 can limit the moving range of the roller 1 in the circumferential direction, thereby avoiding the phenomena of deviation and abrasion caused by the shaking of the roller 1.

Advantageously, on both sides of the vertical central plane of the drum 1, there are supporting assemblies 3 in contact engagement with the drum 1.

Specifically, as shown in fig. 2 and 3, the number of the support assemblies 3 is two, and the two support assemblies 3 are respectively disposed at both sides of the vertical central plane of the drum 1.

Optionally, as shown in fig. 3, included angles formed between connection surfaces of the central axes of the two drums 1 and the central axes of the drums 1 and the vertical central plane are not equal, and heights of the two supporting assemblies 3 are not equal.

As shown in fig. 3, an included angle formed between the surface passing through the central axis of one support component 3 and the central axis of the roller 1 and the vertical central plane is a, an included angle formed between the surface passing through the central axis of the other support component 3 and the central axis of the roller 1 and the vertical central plane is b, and the included angle a is not equal to the included angle b.

Of course, in the embodiment of the present invention, it is not excluded that the supporting component 3 is only one, and when the supporting component 3 is one, the roller 32 of the supporting component 3 can be supported right below the roller 1. In order to ensure the rolling stability of the roller 1, the side surface of the roller 1 can be matched with other structures to support the roller 1.

The structure of the drum 1 and the support member 3 in one embodiment will be described below with reference to the embodiment of fig. 3 to 5.

In this embodiment, the drum 1 includes: barrel 11, barrel back cover 12 and barrel front cover 13, barrel 11 is open at both ends around, and barrel back cover 12 is established in barrel 11's rear end in order to seal barrel 11's rear end. The front cover 13 is arranged at the front end of the barrel body part 11, the front cover 13 is arranged around the central axis of the barrel body part 11 to define the barrel opening 10, and the rollers 32 are in contact fit with the front cover 13.

Since the roller 32 is in contact with the maximum diameter of the drum 1, when the roller 32 is in contact fit with the drum front cover 13, the drum front cover 13 has a section with a diameter equal to or larger than the drum body 11, and the roller 32 is in contact with the section of the drum front cover 13.

The roller 32 is matched in this way, the barrel front cover 13 and the barrel body part 11 can not contact the end face of the roller 32, the structure of the barrel front cover 13 is favorably improved, the processing technology is simplified, the barrel body part 11 can be longer without avoiding the roller 32, and the volume of the roller 1 is enlarged.

Specifically, as shown in fig. 4 and 5, the cartridge front cover 13 includes: a first section 131, a second section 132, a third section 133 and a fourth section 134 which are respectively annular, the first section 131 is sleeved on the second section 132, the front edge of the first section 131 is connected with the front edge of the second section 132 to define a slot 138 which is opened backwards, the third section 133 extends inwards along the radial direction from the rear edge of the second section 132, the fourth section 134 extends forwards from the inner peripheral edge of the third section 133, the surrounded part of the fourth section 134 forms the cylinder opening 10, wherein the front end of the cylinder body part 11 is inserted into the slot 138, and the roller 32 is contacted and matched with the first section 131.

Wherein the drum 1 is reduced in diameter at the third and middle sections 133, 134, the third and fourth sections 133, 134 defining the mouth 14 of the drum 1. It can be understood that if the roller 32 is in contact with the fourth section 134 of the cartridge front cover 13, when the axial length of the fourth section 134 is insufficient, the end surface of the roller 32 easily touches the third section 133, resulting in excessive wear of the roller 32. If the axial length of the fourth section 134 is set longer to avoid the end surface of the roller 32 from contacting the third section 133, the volume of the drum 1 is reduced. Thus, by providing the roller 32 at the first segment 131, the end surface of the roller 32 is prevented from contacting the drum 1. At this time, the axial dimension of the nip 14 of the drum 1 can be reduced without affecting the roller 32.

Specifically, as shown in fig. 5, the axial dimension of the drum 1 is greater than the axial dimension of the first segment 131, so that the axial length of the first segment 131 can be fully utilized to expand the length of the contact line of the roller 32 with the drum 1. The axial length of the drum 1 in fig. 5 is the length of the drum 1 in the front-rear direction.

Further, as shown in fig. 5, the cartridge front cover 13 further includes: and an annular fifth section 135, the fifth section 135 being connected between the third section 133 and the fourth section 134, and the fifth section 135 gradually extending forward in the outside-in direction.

Optionally, the axial cross-section of the fifth segment 135 is a forward convex arc shape, so that the front cover 13 of the cartridge is more resistant to crushing. Wherein an axial cross-section of the fifth segment 135 refers to a projection of the fifth segment 135 on a cross-section through its central axis.

Advantageously, the fifth segment 135 is connected to the third segment 133 and the fourth segment 134 by a circular arc transition.

Specifically, as shown in fig. 5, the front end of the fourth section 134 is rolled outward to form a bead 139.

Further, as shown in fig. 5, the front end of the shaft part 11 is folded back and forth to form a burring 111, the rear edge of the first section 131 extends forward and inward of the slot 138 to form a sixth section 136, and the burring 111 is sandwiched between the first section 131 and the sixth section 136. The first section 131, the second section 132 and the sixth section 136 form a winding structure with the front end of the shaft part 11, so as to improve the connection tightness.

In this embodiment, the roller 32 of the support member 3 is connected to the peripheral body unit 2 through the axle 31, and the roller 32 is supported at the front end of the drum 1 with the axle 31 parallel to the central axis of the drum 1.

The roller 32 is directly in matching contact with the position with the maximum diameter of the roller 1 instead of the position of the closing-in 14 of the roller 1, so that the structure of the front cover 13 of the roller is improved, and the processing technology of the front cover is simplified; the barrel body part 11 can be longer without avoiding the roller 32, and the volume of the roller 1 is enlarged; the axial section of the roller 32 is a plane, the contact with the roller 1 is a line contact, the contact part is long, and the matching operation is stable.
