DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0033] See also Figure 1-Figure 2 The present embodiment provides a clothing processing device 1, which can be widely used in various scenarios such as homes, hotels, hospitals, and laundries. The clothing processing device 1 may include, but is not limited to, a washing machine, a dryer, a clothes dryer, or a clothing care machine. This embodiment of the present application does not specifically limit this. The following example illustrates the clothing processing device 1 as a washing machine.

[0034] Please continue reading Figure 1-Figure 2The washing machine may include a cabinet 10 , a door 20 , and a hinge assembly 30 .

[0035] Specifically, the housing 10 is typically composed of a variety of materials, and the present embodiment does not specifically limit the materials used for the housing 10. For example, the outer shell material of the housing 10 includes, but is not limited to, at least one of metal, plastic, and a composite material. Furthermore, the housing 10 has a laundry processing chamber 10a and an access opening 10b. The laundry processing chamber 10a is connected to the access opening 10b, and a user can place laundry into the laundry processing chamber 10a through the access opening 10b.

[0036] The door 20 is rotatably connected to the housing 10, allowing it to open and close the access opening 10b. It is understood that the door 20 serves to seal the access opening 10b and protect the laundry processing chamber 10a. That is, when the user does not need to place laundry from the access opening 10b into the laundry processing chamber 10a, or when laundry does not need to be removed from the laundry processing chamber 10a, the door 20 rotates relative to the housing 10 to seal the access opening 10b. In particular, when the washing machine is in operation, the door 20 is used to seal the access opening 10b to prevent the user from placing their hands or other objects from the access opening 10b into the laundry processing chamber 10a, thereby ensuring the safety of the washing machine.

[0037] Furthermore, one end of the hinge assembly 30 is rotatably connected to the door body 20, and the other end of the hinge assembly 30 is rotatably connected to the box body 10, so that the door body 20 is rotatably connected relative to the box body 10. It can be understood that the hinge assembly 30 is used to connect the door body 20 and the box body 10. During the rotation of the door body 20, the hinge assembly 30 also rotates, thereby realizing the rotation of the door body 20 relative to the box body 10.

[0038] The hinge assembly 30 will be described in detail below.

[0039] See also Figure 3-Figure 5 The hinge assembly 30 may include a first link 31 and a second link 32 .

[0040] Specifically, the first end 311 of the first connecting rod is used for rotational connection with the box body 10, the second end 312 of the first connecting rod is used for rotational connection with the door body 20, the first end 321 of the second connecting rod is used for rotational connection with the box body 10, and the second end 322 of the second connecting rod is used for rotational connection with the door body 20. In other words, the first connecting rod 31 and the second connecting rod 32 are used to connect the door body 20 and the box body 10, so that the door body 20 can be rotatably connected relative to the box body 10.

[0041] Furthermore, the first connecting rod 31 has an accommodating space 31a extending along its length direction AA, and the second connecting rod 32 is always at least partially located within the accommodating space 31a. It will be understood that during the rotation of the door body 20 relative to the housing 10, the first connecting rod 31 and the second connecting rod 32 will rotate in the direction of movement of the door body 20. However, because the second connecting rod 32 is always at least partially located within the accommodating space 31a, a gap is prevented from forming between the second connecting rod 32 and the outer surface of the first connecting rod 31 during the rotation of the door body 20 relative to the housing 10. In other words, during the rotation of the door body 20 relative to the housing 10, no gap is formed between the second connecting rod 32 and the outer surface of the first connecting rod 31, thereby preventing a user's hand from entering the gap and thereby improving the safety of the washing machine. Of course, when the door body 20 is not rotating, no gap is also required between the first connecting rod 31 and the second connecting rod 32 to prevent a user's hand from entering the gap.

[0042] Furthermore, if there is a gap between the first connecting rod 31 and the second connecting rod 32, clothing can easily fall into the gap when the user takes or places clothing. As the first connecting rod 31 and the second connecting rod 32 move, clothing can become trapped in the gap, causing damage to the clothing and reducing the user experience. Therefore, by ensuring that the second connecting rod 32 is always at least partially located within the accommodating space 31a, a gap is eliminated between the second connecting rod 32 and the outer surface of the first connecting rod 31, preventing clothing from becoming trapped and thereby improving the user experience.

[0043] In the embodiment of the present application, the first connecting rod 31 is provided with a accommodating space 31a extending along its own length direction AA, and the second connecting rod 32 is always at least partially located in the accommodating space 31a; that is, during the rotation of the door body 20 relative to the box body 10, since the second connecting rod 32 is always at least partially located in the accommodating space 31a, no gap is generated between the outer surface of the second connecting rod 32 and the first connecting rod 31, so as to avoid the user's hand reaching into the gap, thereby improving the safety of using the clothing processing device 1.

[0044] It should be noted that the rotation angle of the door 20 from the position of closing the access opening 10b to the position of opening the access opening 10b is α, and α is not less than 70 degrees and not greater than 190 degrees. That is, the angle α can be 70 degrees, 90 degrees, 110 degrees, 150 degrees, and 190 degrees. This makes it easier for users to place clothes from the access opening 10b into the laundry processing chamber 10a, while also saving space in the washing machine. The rotational space swept by the door 20 when it rotates is equal to the length of the door 20 multiplied by the rotation angle. If α is less than 70 degrees, the rotational space of the door 20 relative to the housing 10 is small, making it difficult for users to place clothes into the laundry processing chamber 10a. If α is greater than 190 degrees, the rotational space of the door 20 relative to the housing 10 is large, and users need to reserve more space for the washing machine to ensure that the door 20 can open or close smoothly.

[0045] See also Figure 3-Figure 4 In some embodiments, the accommodating space 31a may be an accommodating groove 31b, which extends through both ends of the first connecting rod 31 along the length direction AA of the first connecting rod 31. The accommodating groove 31b further includes an accommodating notch 31c formed on one of the side walls 313 of the first connecting rod 31. It is understood that the second connecting rod 32 may extend into the accommodating groove 31b from both ends of the first connecting rod 31, or the second connecting rod 32 may extend into the accommodating groove 31b from the accommodating notch 31c. This embodiment of the present application does not impose specific requirements on this.

[0046] Furthermore, during the rotation of the door body 20 relative to the housing 10, the second connecting rod 32 moves relative to the first connecting rod 31 through the accommodating notch 31c. That is, during the rotation of the door body 20 relative to the housing 10, both the first connecting rod 31 and the second connecting rod 32 can rotate, and the second connecting rod 32 moves within the accommodating notch 31b. Therefore, the second connecting rod 32 is always at least partially located within the accommodating space 31a, thereby preventing a gap from being formed between the second connecting rod 32 and the outer surface of the first connecting rod 31, thereby preventing a user's hand from reaching into the gap. In this way, the safety of the laundry processing device 1 is improved.

[0047] In the related art, the door 20 can have various functional modules, such as a display control panel and light box lighting. In this case, the functional modules need to communicate with the main controller inside the cabinet 10 via wires. However, when the door 20 is open, the wires connecting the door 20 and the cabinet 10 may be exposed, which not only affects the appearance of the washing machine, but also makes the wires easily come into contact with water, which may cause electric shock accidents.

[0048] See also Figure 6-Figure 7Therefore, in some embodiments, the accommodating groove 31b has a groove bottom wall arranged opposite to the accommodating groove opening 31c, and a wiring channel 31d is constructed between the second connecting rod 32 and the groove bottom wall. The wiring channel 31d is used to accommodate the wires connecting the door body 20 and the box body 10. It can be understood that when at least a portion of the second connecting rod 32 is installed in the accommodating space 31a, a wiring channel 31d can be formed between the second connecting rod 32 and the groove bottom wall, so that the conductor passes through the wiring channel 31d, thereby connecting the door body 20 and the box body 10; and because the wiring channel 31d is arranged in the accommodating groove 31b, the wires will not be exposed when the door body 20 is in the open state. In this way, not only the aesthetics of the washing machine is ensured, but also the safety of the washing machine is improved.

[0049] In some embodiments, the minimum dimension of the wiring channel 31d, as measured from the receiving notch 31c toward the bottom wall of the slot, is greater than or equal to 4 mm. That is, the minimum dimension of the wiring channel 31d can be 4 mm, 6 mm, 8 mm, or 10 mm. This facilitates the passage of wires through the wiring channel 31d. If the minimum dimension of the wiring channel 31d is less than 4 mm, the space available for the wires to pass through the wiring channel 31d is limited. When there are multiple wires, the smaller dimension of the wiring channel 31d makes it difficult for the wires to pass through the wiring channel 31d.

[0050] In some embodiments, the first connecting rod 31 is a tubular structure, and the accommodating space 31a has openings at both ends along the longitudinal direction AA of the tubular structure. The second connecting rod 32 is always disposed within the accommodating space 31a, with the first end 321 of the second connecting rod extending through one of the openings, and the second end 322 of the second connecting rod extending through the other opening. It is understood that the second connecting rod 32 can extend into the accommodating space 31a through the openings at both ends of the tubular structure, so that at least a portion of the second connecting rod 32 is always disposed within the accommodating space 31a. That is, during the rotation of the door body 20 relative to the housing 10, at least a portion of the second connecting rod 32 is always located within the accommodating space 31a, thereby preventing a gap from forming between the second connecting rod 32 and the outer surface of the first connecting rod 31, thereby preventing a user's hand from entering the gap. This improves the safety of the laundry processing device 1.

[0051] See also Figure 3 as well as Figure 5In some embodiments, the hinge assembly 30 further includes two hinge seats 33. Specifically, the first end 311 of the first connecting rod and the first end 321 of the second connecting rod are both rotatably connected to one of the hinge seats 33, and the second end 312 of the first connecting rod and the second end 322 of the second connecting rod are both rotatably connected to the other hinge seat 33. One of the hinge seats 33 is used for fixed connection to the box body 10, and the other hinge seat 33 is used for fixed connection to the door body 20. That is, one of the hinge seats 33 is fixed to the mounting box 10, and one of the hinge seats 33 is rotatably connected to the first connecting rod 31 and the second connecting rod 32; at the same time, the other hinge seat 33 is fixedly mounted on the door body 20, so that the other hinge seat 33 is rotatably connected to the first connecting rod 31 and the second connecting rod 32, thereby achieving rotation of the door body 20 relative to the box body 10.

[0052] See also Figure 5 Furthermore, in some embodiments, each hinge seat 33 includes a connecting plate 331 and two side plates 332 .

[0053] Specifically, the connecting plates 331 of the two hinge bases 33 are respectively used to be fixedly connected to the door body 20 and the box body 10. That is, the connecting plate 331 of one hinge base 33 is fixedly connected to the box body 10, and the connecting plate 331 of the other hinge base 33 is fixedly connected to the door body 20. The two side plates 332 of each hinge base 33 are fixedly connected to the connecting plate 331 and are spaced apart to form a first mounting groove 332a. It is understood that the first end 311 of the first connecting rod and the first end 321 of the second connecting rod are installed in the first installation groove 332a formed by the two side plates 332 of one hinge seat 33, so that the first end 311 of the first connecting rod and the first end 321 of the second connecting rod are both rotatably connected to the side plates 332; the second end 312 of the first connecting rod and the second end 322 of the second connecting rod are installed in the first installation groove 332a formed by the two side plates 332 of the other hinge seat 33, so that the second end 312 of the first connecting rod and the second end 322 of the second connecting rod are both rotatably connected to the side plates 332. In other words, during the rotation of the door body 20, the door body 20 can drive the first connecting rod 31 and the second connecting rod 32 to move, thereby realizing the rotation of the door body 20 relative to the box body 10.

[0054] It should be noted that the shapes of the two hinge seats 33 may be the same or different, and this embodiment of the present application does not specifically limit this.

[0055] Please continue reading Figure 5Furthermore, in some embodiments, both side panels 332 of one hinge base 33 are provided with a first shaft hole 3321; the first end 311 of the first connecting rod is provided with a second shaft hole 314; and the hinge assembly 30 further includes a first rotating shaft (not shown in the figure), which passes through the first shaft hole 3321 and the second shaft hole 314 to rotatably connect the first end 311 of the first connecting rod to the two side panels 332. That is, the first rotating shaft passes from the first shaft hole 3321 on one side panel 332 through the second shaft hole 314 and then passes through the first shaft hole 3321 on the other side panel 332, thereby achieving rotatable connection between the first end 311 of the first connecting rod and the two side panels 332.

[0056] Furthermore, both side panels 332 are provided with a third shaft hole 3322; the first end 321 of the second connecting rod is provided with a fourth shaft hole 323; and the hinge assembly 30 further includes a second rotating shaft (not shown), which passes through the third shaft hole 3322 and the fourth shaft hole 323 to rotatably connect the first end 321 of the second connecting rod to the two side panels 332. In other words, the second rotating shaft passes from the third shaft hole 3322 on one side panel 332 through the fourth shaft hole 323 and then into the third shaft hole 3322 on the other side panel 332, thereby achieving rotatable connection between the first end 321 of the second connecting rod and the two side panels 332.

[0057] Please continue reading Figure 5 In addition, since there are two hinge seats 33, and the second end 312 of the first connecting rod and the second end 322 of the second connecting rod are installed in the other first installation groove 332a and are both rotatably connected to the side plate 332, the two side plates 332 on the other hinge seat 33 are each provided with a fifth axis hole 3323, and the second end 312 of the first connecting rod is provided with a sixth axis hole 315. The hinge assembly 30 also includes a third rotating shaft (not shown in the figure), which passes through the fifth axis hole 3323 and the sixth axis hole 315 so that the second end 312 of the first connecting rod can be rotatably connected to the two side plates 332; the two side plates 332 on the other hinge seat 33 are also provided with a seventh axis hole 3324, and the second end 322 of the second connecting rod is provided with an eighth axis hole 324. The hinge assembly 30 also includes a fourth rotating shaft (not shown in the figure), which passes through the seventh axis hole 3324 and the eighth axis hole 324 so that the second end 322 of the second connecting rod can be rotatably connected to the two side plates 332.

[0058] It should be noted that the embodiments of the present application do not specifically limit the specific types of the first rotating shaft, the second rotating shaft, the third rotating shaft, and the fourth rotating shaft. For example, the first rotating shaft, the second rotating shaft, the third rotating shaft, and the fourth rotating shaft can all be latch shafts.

[0059] In the related art, the hinge assembly 30 generally has a single rotation center, which results in a larger rotation space for the door body 20 relative to the box body 10. In the embodiment of the present application, the first end 311 of the first connecting rod is provided with a first shaft hole 3321 and a second shaft hole 314 through a first rotating shaft, so that the first end 311 of the first connecting rod is rotatably connected to the two side panels 332; the first end 321 of the second connecting rod is provided with a third shaft hole 3322 and a fourth shaft hole 323 through a second rotating shaft, so that the first end 321 of the second connecting rod is rotatably connected to the two side panels 332; that is, the first end 311 of the first connecting rod has one rotation center point, and the first end 321 of the second connecting rod has another rotation center point, thereby solving the problem of large rotation space caused by a single rotation center.

[0060] Please continue reading Figure 5 In some embodiments, a notch 316 is provided at a position on the side wall 313 corresponding to the fourth shaft hole 323 to expose the fourth shaft hole 323. That is, since the second connecting rod 32 is always at least partially installed in the accommodating space 31a, in order to facilitate the second rotating shaft to pass through the fourth shaft hole 323 on the first end 321 of the second connecting rod, the embodiment of the present application provides a notch 316 at a position on the side wall 313 corresponding to the fourth shaft hole 323 to expose the fourth shaft hole 323, thereby facilitating the second rotating shaft to pass through the fourth shaft hole 323. In this way, the second connecting rod 32 is rotatably connected to the side plate 332.

[0061] See also Figure 3 as well as Figure 5 In some embodiments, the first connecting rod 31 includes two opposing side walls 313 defining an accommodating space 31a therebetween. The width of the side walls 313 gradually increases from one hinge seat 33 toward the other hinge seat 33. It will be appreciated that because the second connecting rod 32 is always at least partially mounted within the accommodating space 31a, the embodiment of the present application utilizes a configuration in which the width of one hinge seat gradually increases toward the other hinge seat to prevent the second connecting rod 32 from disengaging from the accommodating space 31a during movement, thereby preventing a gap from forming between the second connecting rod 32 and the outer surface of the first connecting rod 31.

[0062] It should be noted that the door body 20 can be rotated upward relative to the box body 10, or the door body 20 can be rotated downward relative to the box body 10, and this embodiment of the present application does not specifically limit this.

[0063] For example, when the door body 20 rotates upward relative to the box body 10, the closer to the hinge seat fixedly connected to the door body 20, the larger the width of the two side walls 313 of the first connecting rod 31 should be, so as to prevent the second connecting rod 32 from escaping from the accommodating space 31a during movement.

[0064] For example, when the door body 20 rotates downward relative to the box body 10, the closer to the hinge seat 33 fixedly connected to the box body 10, the larger the width of the two side walls 313 of the first connecting rod 31 should be, so as to prevent the second connecting rod 32 from escaping from the accommodating space 31a during movement.

[0065] In some embodiments, the length of the first connecting rod 31 is smaller than the length of the second connecting rod 32, so that the second end 322 of the second connecting rod can pass through the accommodating space 31a. In other words, by setting the length of the first connecting rod 31 to be smaller than the length of the second connecting rod 32, the second end 322 of the second connecting rod can pass through the accommodating space 31a and be rotatably connected to the side plate 332 of the other hinge base 33.

[0066] See also Figure 8 In some embodiments, the number of hinge assemblies 30 can be two, with the two hinge assemblies 30 spaced apart in the left-right direction BB of the laundry processing apparatus 1. That is, the hinge assemblies 30 are spaced apart in the left-right direction BB of the door body 20. When the door body 20 rotates, the two hinge assemblies 30 work together to provide uniform support for the door body 20, thereby preventing deformation caused by excessive pressure on a single hinge assembly 30. Furthermore, by providing two hinge assemblies 30, the weight of the door body 20 is dispersed, thereby enhancing the stability of the door body 20.

[0067] See also Figure 8-Figure 9 In some embodiments, a second mounting groove 20a is provided on the surface of the door 20 facing the housing 10, and the first connecting rod 31 and the second connecting rod 32 are at least partially installed in the second mounting groove 20a. It is understandable that when the door 20 is in a position closing the access opening 10b, the first connecting rod 31 and the second connecting rod 32 are installed in the second mounting groove 20a, thereby saving the size of the washing machine. Moreover, the first connecting rod 31 and the second connecting rod 32 are at least partially installed in the second mounting groove 20a. When the door 20 is in a state closing the access opening 10b, the gap between the door 20 and the housing 10 can be reduced to prevent the user's hand from reaching into the gap, thereby improving the safety of the washing machine.
