Detailed implementation manners

[0028] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0029] Embodiments of the present disclosure provide a laundry treatment device, which may include a housing 10 and a first drum 30. Refer to Figures 1 to 3 , the first drum 30 may be disposed within the housing 10, and the first drum 30 may be through Figure 1The exemplary suspension beam 12 is installed on the housing 10. A first through hole 301 may be formed at a position near the bottom of the first roller 30. A second through hole 101 corresponding to the first through hole 301 may be formed on the housing 10. A positioning rod 80 may be provided between the housing 10 and the first roller 30. The positioning rod 80 is detachably inserted through the first through hole 301 and the second through hole 101 at the same time, so that the first roller 30 is locked to the housing 10, forming a fixed connection between the first roller 30 and the housing 10, and preventing the first roller 30 from moving freely relative to the housing 10.

[0030] Through the above technical solution, the first through hole 301 is provided at a position near the bottom of the first roller 30, the second through hole 101 corresponding to the first through hole 301 is provided on the housing 10 of the device, and the first roller 30 can be locked to the housing 10 through the positioning rod 80 inserted through the first through hole 301 and the second through hole 101. Since the first through hole 301 is provided at the bottom of the first roller 30, it can bear the gravity of the first roller 30, so as to prevent the first roller 30 from shaking relative to the housing 10 during handling. When the device drops, it can effectively support the first roller 30, avoiding collision with other internal structures (such as the second roller 20 below) and causing damage, and ensuring the safety and stability of the device during transportation.

[0031] In the above embodiment, one end of the positioning rod 80 may be provided with a thread. When it is inserted into the first through hole 301 and the second through hole 101, a nut can be used to screw with the threaded end of the positioning rod 80 to stably position the positioning rod 80 to the housing 10 from the outside of the device, and then limit the rotational movement or vibration movement of the first roller 30 through the positioning rod 80, improving the stability of the internal structure of the device. The embodiment of the present disclosure does not specifically limit the fixing method of the positioning rod 80. For example, one or both of the first through hole 301 and the second through hole 101 may be set as threaded holes, and the corresponding preset rod section of the positioning rod 80 may be set as a threaded section, and the positioning rod 80 is screwed into one or both of the first through hole 301 and the second through hole 101 to fix the positioning rod 80. In addition, engaging structures may be respectively provided on the rod body of the positioning rod 80 and the inner circumference of the corresponding through hole, so that the positioning rod 80 can be clamped with the corresponding through hole at a preset position to form a fixation, or a magnetic attraction structure may be used, so that the positioning rod 80 can be magnetically fixed in the through hole to limit the movement of the first roller 30. At this time, the magnetic attraction force used to fix the positioning rod 80 satisfies that the positioning rod 80 is not easily separated from the through hole, so as to improve the fixing effect of the positioning rod 80. Of course, other methods may also be used to achieve the purpose of fixing the positioning rod 80 between the first roller 30 and the housing 10, which will not be elaborated here.

[0032] In other embodiments, the outer shell 10 may be provided with multiple groups of second through holes 101 along the axial direction of the first drum 30, and there is a certain interval between the axes of any two groups of second through holes 101, so that after multiple positioning rods 80 pass through each group of second through holes 101, they can provide multi-point support for the first drum 30 from the outer peripheral wall of the first drum 30, thereby restricting the rotational movement and vibration movement of the first drum 30 through multiple support points, having a better fixing effect and effectively improving the stability and safety of the first drum 30. In this embodiment, the multiple second through holes 101 may be respectively arranged on the outer shell 10 at the front end and the rear end of the first drum 30, so that the positioning rod 80 can pass through the second through holes 101 in the front-rear direction of the device, or the outer shell has a certain thickness, and multiple spaced second through holes 101 are opened in this thickness direction. In addition, the outer shell 10 at any end of the first drum 30 may be provided with a plurality of layers, and the multiple second through holes 101 may be respectively arranged on the outer shell 10 of the plurality of layers. The positioning rod 80 does not need to penetrate the device in the front-rear direction of the device, and only needs to position the outer peripheral wall of a part of the length of the first drum 30, effectively reducing the space volume occupied by the positioning rod 80, reducing the weight of the positioning rod 80, and facilitating the transportation of the device. The front and rear here are defined according to the direction of the laundry treatment device during use. The side facing the user is the front, and the opposite is the rear. Specifically, reference may be made to Figure 1 and Figure 3 the directions indicated by the arrows.

[0033] Exemplarily, with reference to Figures 1 to 3, a first crossbeam 11 may be installed in the housing 10, and a third through hole 111 may be opened on the first crossbeam 11, and the third through hole 111 may be arranged corresponding to the first through hole 301 and the second through hole 101, so as to allow the positioning rod 80 to pass through. In this embodiment, by installing the first crossbeam 11 in the housing 10 and adding the third through hole 111 on the first crossbeam 11, the support points of the positioning rod 80 are increased, so that when the first roller 30 generates a movement trend, the force can be dispersed through multiple support points, avoiding stress concentration at a single limiting point, and improving the stability of the first roller 30 and the service life of the positioning structure. In addition, the support point is set on the first crossbeam 11 in the housing 10 to avoid adding too many support holes on the housing 10, which affects the appearance of the device. The first crossbeam 11 can be a mounting beam for wiring and pipe routing of the device. Setting the third through hole 111 on the first crossbeam 11 can effectively utilize the original structure of the device, save the number of parts and the occupation of internal space. It should be noted that when the housing 10 supports the positioning rod 80 at least through the second through hole 101 and the third through hole 111, the positioning rod 80 may not be fixedly connected to the second through hole 101 or the third through hole 111. Under simple transport conditions (such as transport in a horizontal straight line), the positioning rod 80 may only pass through each through hole in turn to facilitate installation and disassembly, thereby simplifying the transport process. In addition, other limiting structures may be added to the first crossbeam 11 to fix wires or water pipes, and may be used to fix other structures inside the equipment that are prone to swing or shaking (such as drying air ducts, etc.), thereby reasonably improving the utilization rate of the first crossbeam 11.

[0034] In some embodiments, reference Figure 3 , one of the second through hole 101 and the third through hole 111 may be located in front of the first through hole 301, and the other may be located behind the first through hole 301, so as to form a clamping positioning at the front and rear sides of the first through hole 301. This arrangement allows the two ends of the positioning rod 80 to be fixed to the housing 10 through the third through hole 111 and the second through hole 101, respectively, and the first through hole 301 is limited to the middle section of the positioning rod 80 relative to the second through hole 101 and the third through hole 111, which can effectively improve the stability of the positioning rod 80.

[0035] In some embodiments, reference Figure 7 , a reinforcing rib 112 may be formed on the first beam 11, and the reinforcing rib 112 may extend along the extension direction of the first beam 11 on both sides of the third through hole 111, so as to improve the structural strength and force bearing capacity of the first beam 11 and the third through hole 111, prevent the first beam 11 or the third through hole 111 from deforming when subjected to a large force, and improve the overall stability of the device. The horizontal direction in this article generally refers to the left and right direction when the user faces the front end of the clothing processing device, and it can also be defined according to the specific extension direction of the beam.

[0036] In some embodiments, reinforcing structures may be formed circumferentially around the second via 101 and the third via 111, such as reinforcing protrusions, to enhance the structural strength and stress-bearing capacity of both when restricting the movement of the first drum 30, and to prevent the failure of the movement restriction of the first drum 30 due to deformation or breakage.

[0037] Exemplarily, referring to Figures 4 to 6 , a flange 31 may be installed at the end of the first drum 30. The first drum 30 may include an outer cylinder 302 and an inner cylinder 303. Among them, the inner cylinder 303 is rotatably disposed within the outer cylinder 302. The flange 31 may be connected to the outer cylinder 302, and the first via 301 may be formed at a position near the bottom of the flange 31. In this embodiment, the flange 31 is connected to the outer cylinder 302, and the first via 301 is formed at a position near the bottom of the flange 31, such that when the positioning rod 80 passes through the first via 301, the rotational movement and vibration movement of the outer cylinder 302 can be restricted. Setting the first via 301 at a position near the bottom of the flange 31 can also support the gravity of the first drum 30 in the height direction when the positioning rod 80 passes through the first via 301, reducing the stress on other limiting structures for fixing the first drum 30.

[0038] Meanwhile, setting the via on the flange 31 can avoid damaging the outer shape and wall structure of the outer cylinder 302 of the first drum 30, thereby affecting the service strength of the first drum 30. When the first drum 30 is arranged diagonally above the second drum 20 described below, the bottom space of the flange 31 has a certain accommodation volume. Arranging the first via 301 at the bottom can improve the space utilization rate around the first drum 30, making the layout of each structure inside the device compact and further enhancing the overall stability of the device. The embodiments of the present disclosure do not specifically limit the connection manner between the flange 31 and the first drum 30, and the two can be fixed by means such as bolt bolting, welding, or clamping with a clamping structure, which will not be elaborated here. After being connected to the outer cylinder 302, the flange 31 can be used for installing a door seal, and the flange 31 can be provided with a certain avoidance structure (such as an avoidance groove) to avoid the possibility of collision between the flange 31 and other installation structures inside the device (such as the water inlet pipeline or drying air duct of the first drum 30), thereby enhancing the service stability of the first drum 30.

[0039] In some embodiments, referring to Figure 5 , a semi-circular reinforcing rib 314 may be formed on the lower half of the flange 31, which can increase the structural strength of the lower half and the bottom of the flange 31 and improve the overall load-bearing capacity of the flange 31. And on the premise of ensuring strength, the semi-circular reinforcing rib 314 is arranged on the lower half of the flange 31 to avoid interference with the structures (such as the water inlet pipeline or drying air duct, etc.) on the upper half of the flange 31, and has a certain vibration avoidance distance to prevent collision with other structures when the first drum 30 vibrates or shakes.

[0040] In some embodiments, referring to Figure 5 , the flange 31 may include a lug 315 protruding downward at the bottom. The first through hole 301 may be formed in the lug 315. A plurality of strip-shaped reinforcing ribs 316 may be formed on the lug 315, and the plurality of strip-shaped reinforcing ribs 316 may be divergently connected between the first through hole 301 and the semi-circular reinforcing rib 314 starting from the first through hole 301. In this embodiment, the first through hole 301 and the central axis of the first roller 30 are at the same vertical height, so that the center of gravity of the first roller 30 can be projected onto the axis of the first through hole 301 in the height direction. When the positioning rod 80 passes through the first through hole 301, the positioning rod 80 can be used to non-eccentrically bear part of the weight of the first roller 30, improving the limiting effect on the first roller 30. At the same time, the lugs 315 can be symmetrically arranged on both sides of the connection line between the first through hole 301 and the axis of the first roller 30, and the plurality of strip-shaped reinforcing ribs 316 can also be symmetrically arranged with this connection line as the axis of symmetry, diverging and connecting evenly from the first through hole 301 to the semi-circular reinforcing rib 314 to balance the structural strength on both sides of the bottom of the first roller 30. When the lugs 315 bear the force, they can evenly support or limit the first roller 30, improving the service life of the flange 31 and the structural stability of the first roller 30.

[0041] Exemplarily, the diameter of the first roller 30 may be 175 mm to 185 mm. Combining Figure 8 , the distance D2 from the center of the first roller 30 to the top wall of the housing 10 may be 122 mm to 127 mm, and the distance D1 from the center of the first roller 30 to the side wall of the housing 10 close to it may be 108 mm to 112 mm. Since the space between the first roller 30 and the top wall and side wall of the housing 10 is limited, and a certain interval needs to be reserved from the housing to avoid collision, in the embodiments of the present disclosure, the first through hole 301 is arranged at the bottom and is set to be one to avoid occupying the lateral space of the first roller 30. Moreover, while ensuring the structural volume and setting range of the first through hole 301 and the flange 31, the surrounding structure of the first roller 30 can be set more compactly, improving the overall stability inside the device.

[0042] In some embodiments, referring to Figure 8, the laundry treating device may further include a second drum 20. The first drum 30 may be located obliquely above the second drum 20 to reduce the overall height of the device and the space occupation. The diameter of the second drum 20 may be 533 mm to 543 mm. When the diameter of the first drum 30 is 175 mm to 185 mm, the diameter of the second drum 20 is much larger than that of the first drum 30. Therefore, the first drum 30 can be arranged by using the space obliquely above the second drum 20 to reduce the vertical or lateral dimension of the device, so as to reduce the volume of the device. Among them, in the vertical direction, the distance D3 between the axis of the first drum 30 and the axis of the second drum 20 may be 150 mm to 220 mm, for example, it may be 160 mm, 180 mm or 200 mm, etc. In the horizontal direction, the distance D4 between the axis of the first drum 30 and the axis of the second drum 20 may be 300 mm to 350 mm, for example, it may be 305 mm, 325 mm or 345 mm, etc., to ensure that there is enough safety distance between the first drum 30 and the second drum 20. The water pipe lines, wire lines and drying air ducts respectively related to the two drums can be arranged within the safety distance therebetween, and the first drum 30 and the second drum 20 are arranged obliquely opposite to each other, which can ensure that the flange 31, the lug 315 thereon and the first through hole 301 do not interfere with or collide with the second drum 20, and have good relative stability.

[0043] In the embodiments of the present disclosure, since the volume of the second drum 20 is relatively large, multiple positioning points can be set for positioning during transportation. For example, more than two positioning holes can be provided at the bottom of the second drum 20, and a second cross beam can be provided in the housing 10 to support the second drum 20 together with the housing 10.
