[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0041] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0042] In view of the problem that in the prior art, clothing processing devices with a waterless design or a design without an outer drum between the inner and outer drums are generally provided with two doors. When taking and placing clothes before and after the clothing processing device works, the two doors need to be opened, which is repetitive. In addition, the door installed on the inner drum cannot be opened to a large angle due to the length of the rotating arm, which makes it inconvenient to take and place clothes. This embodiment provides a hinge structure and a clothing processing device to solve the above problem.

[0043] Figure 1 is a schematic structural diagram of the clothes processing device provided in this embodiment when the door is open; Figure 2 3 is a schematic structural diagram of the clothes processing device provided in this embodiment when the door is closed.

[0044] Specifically, if Figure 1 and Figure 2 As shown, the hinge structure provided in this embodiment includes a first hinge shaft 11, a second hinge shaft 21 and a rotating arm 3. The first hinge shaft 11 is used to be installed on the inner cylinder 100, the second hinge shaft 21 is used to be installed on the front plate 200, and the rotating arm 3 is used to be installed on the door body 300. The rotating arm 3 is provided with a first hinge sleeve 31 and a second hinge sleeve 32. When the door body 300 is closed, the first hinge sleeve 31 is rotatably connected to the first hinge shaft 11, and the second hinge sleeve 32 is disengaged from the second hinge shaft 21. When the door body 300 is opened, the second hinge sleeve 32 is rotatably connected to the second hinge shaft 21, and the first hinge sleeve 31 is disengaged from the first hinge shaft 11.

[0045] The rotating arm 3 can be switched and connected with the first hinge shaft 11 and the second hinge shaft 21 to enable the door body 300 to close the sealed inner drum 100 and rotate with the inner drum 100, and to enable the door body 300 to open with a large opening angle, which is convenient for users to take and put clothes. It is suitable for installation on a clothing processing device without water or an outer drum between the inner and outer drums, realizing the design of a single door body 300 of the clothing processing device, making the clothing processing device simple in structure and easy to operate.

[0046] Figure 3is a partial structural diagram of the laundry processing device in this embodiment when the door is open. Figure 4 1 is a schematic diagram of the partial structure of the rotating arm of the clothes processing device in this embodiment when the hinge axis is switched; Figure 5 : is a partial structural diagram of the laundry processing device in this embodiment when the door is closed. Figure 3-5 As shown, the motion trajectory of the first hinge sleeve 31 is an arcuate trajectory centered on the axis of the second hinge shaft 21, with a central angle a of 58°-62°. The motion trajectory of the second hinge sleeve 32 is an arcuate trajectory centered on the axis of the first hinge shaft 11, with a central angle b of 53°-57°. The motion trajectory of the first hinge sleeve 31 is from the state where the first hinge sleeve 31 is fully engaged with the first hinge shaft 11 to the state where the second hinge sleeve 32 is fully engaged with the second hinge shaft 21. The motion trajectory of the second hinge sleeve 32 is from the state where the second hinge sleeve 32 is fully engaged with the second hinge shaft 21 to the state where the first hinge sleeve 31 is fully engaged with the first hinge shaft 11. The relative positions of the first and second hinge shafts 11 and 21, as well as the motion trajectories of the first and second hinge sleeves 31 and 32, enable the rotating arm 3 to smoothly switch between the first and second hinge shafts 11 and 21.

[0047] Furthermore, the central angle a of the motion trajectory of the first hinge sleeve 31 is 58°, 59°, 60°, 61° or 62°, preferably the central angle a is 60°, and the central angle b of the motion trajectory of the second hinge sleeve 32 is 53°, 54°, 55°, 56° or 57°, preferably the central angle b is 55°, so as to make the hinge structure more compact and reduce the space occupied by the hinge structure.

[0048] Figure 6 This is a schematic diagram of the structure of the rotating arm provided in this embodiment. In this embodiment, combined with Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The cross-section of the first hinge shaft 11 is a plane bounded by the major arc and the chord tangent lines connecting the two ends of the major arc. A first opening 311 is defined in the first hinge sleeve 31. The diameter of the first opening 311 is smaller than the diameter of the first hinge shaft 11 and larger than the length of the longest straight line from the major arc perpendicular to the chord tangent line in the cross-section of the first hinge shaft 11. If the diameter of the first opening 311 is larger than the length from the major arc perpendicular to the longest chord tangent line in the cross-section of the first hinge shaft 11 in the direction of separation from the first hinge shaft 11, the first hinge sleeve 31 can be separated from the first hinge shaft 11. The first hinge shaft 11 and the first hinge sleeve 31 have a simple structure and can be connected and separated from the first hinge shaft 11 as the first hinge sleeve 31 rotates.

[0049] The structure of the second hinge shaft 21 is identical to that of the first hinge shaft 11. Specifically, the cross-section of the second hinge shaft 21 is a plane bounded by the major arc and the chord tangent lines connecting the two ends of the major arc. The second hinge sleeve 32 is provided with a second opening 321. The diameter of the second opening 321 is smaller than the diameter of the second hinge shaft 21 and larger than the length of the longest straight line perpendicular to the major arc and the chord tangent lines in the cross-section of the second hinge shaft 21. If the diameter of the second opening 321 is larger than the length of the longest straight line perpendicular to the major arc and the chord tangent lines in the cross-section of the second hinge shaft 21, the second hinge sleeve 32 can be separated from the second hinge shaft 21. The structure of the second hinge shaft 21 and the second hinge sleeve 32 is simple, and the second hinge sleeve 32 can be connected and separated from the second hinge shaft 21 as the second hinge sleeve 32 rotates.

[0050] Further, continue to refer to Figure 2 and Figure 3 The angle c between the extension line of the chord tangent of the first hinge axis 11 and the extension line of the chord tangent of the second hinge axis 21 is 0°-5°, and the chord tangent of the first hinge axis 11 and the chord tangent of the second hinge axis 21 are both set toward the inner cylinder, and the chord tangent of the first hinge axis 11 and the chord tangent of the second hinge axis 21 are both tilted from one end close to the door body 300 to the other end, and tilted toward the side away from the inner cylinder 100. The extension line of the chord tangent of the first hinge axis 11 and the extension line of the chord tangent of the second hinge axis 21 are set at an angle, so that the rotating arm 3 can smoothly switch the connection with the first hinge axis 11 and the second hinge axis 21. The angle c is set to 0°-5°, so that the hinge axis switching connection is good. If it is greater than 5°, there will be a problem that the first hinge sleeve 31 and the first hinge axis 11 cannot be connected. If the chord tangent of the first hinge axis 11 and the chord tangent of the second hinge axis 21 are both tilted from one end near the door body 300 to the other end, and tilted toward the side near the inner cylinder 100, the hinge axis switching will be poor, the hinge sleeve will prematurely separate from the hinge axis, and the door body 300 will fall. Preferably, the angle c between the extension line of the chord tangent of the first hinge axis 11 and the extension line of the chord tangent of the second hinge axis 21 can be 0°, 1°, 2°, 3°, 4°, or 5°, with the preferred central angle c being 5°.

[0051] Furthermore, in this embodiment, the angle d formed between the line connecting the axis of the first hinge axis 11 and the axis of the second hinge axis 21 and the front panel 200 is 8°-10°. The first hinge axis 11 is positioned farther from the front panel 200 than the second hinge axis 21, such that the first hinge axis 11 and the second hinge axis 21 are offset relative to the front panel 200. The spacing L between the axis of the first hinge axis 11 and the axis of the second hinge axis 21 is 29mm-31mm. The aforementioned angle c, angle d, and spacing L determine the installation position of the first hinge axis 11 and the second hinge axis 21, so as to achieve hinge axis switching in conjunction with the first hinge sleeve 31 and the second hinge sleeve 32. Preferably, the angle d formed between the line connecting the axis of the first hinge axis 11 and the axis of the second hinge axis 21 and the front panel 200 can be 8°, 9°, or 10°, with the preferred angle d being 9°. The distance L between the axis of the first hinge axis 11 and the axis of the second hinge axis 21 may be 29 mm, 30 mm, or 31 mm, and the distance L is preferably 30 mm.

[0052] Figure 7 is a schematic diagram of the installation structure of the first hinge axis in this embodiment. In this embodiment, Figure 5 and Figure 7 As shown, the first hinge shaft 11 is connected to a first support arm 12. The first support arm 12 is an L-shaped support arm. One end of the first support arm 12 is connected to the first hinge shaft 11, and the other end of the first support arm 12 is connected to a first mounting base 13. To prevent interference with the rotation of the door body 300, the first support arm 12 is bent away from the door body 300. The first mounting base 13 is mounted on the outer wall of the inner cylinder 100. For ease of installation, the side of the first mounting base 13 that connects to the inner cylinder 100 is curved, allowing it to mate with the outer wall of the inner cylinder 100 and improve the stability of the connection. In other embodiments, the first hinge shaft 11 can also be mounted in other structures, which are not limited here.

[0053] Likewise, if Figure 8 As shown, the second hinge shaft 21 is connected to a second support arm 22. The second support arm 22 is L-shaped, with one end of the second support arm 22 connected to the second hinge shaft 21 and the other end of the second support arm 22 connected to a second mounting base 23. The L-shaped second support arm 22 allows the second mounting base 23 to be mounted inside the front plate 200, enhancing the aesthetics of the laundry processing device. Furthermore, the second support arm 22 bends away from the inner drum 100, preventing interference with the rotation of the door body 300. In other embodiments, the second hinge shaft 21 can be mounted in other configurations, which are not limited here.

[0054] In order to cooperate with the first hinge shaft 11 and the second hinge shaft 21, refer to Figure 6In this embodiment, the first hinge sleeve 31 and the second hinge sleeve 32 are connected by a first connecting member 33, the first hinge sleeve 31 is connected to the door body 300 by a second connecting member 34, and the first opening 311 and the second opening 321 are oriented in the same direction. The first hinge sleeve 31 is arranged close to the door body 300, and the first connecting member 33 can move between the first hinge shaft 11 and the second hinge shaft 21.

[0055] The spacing between the first hinge shaft 11 and the second hinge shaft 21 provides space for the first connector 33 to swing, so that the rotating arm 3 can smoothly switch the hinge shaft. In this embodiment, the first hinge sleeve 31 and the second hinge sleeve 32 are arranged in a manner that matches the manner in which the first hinge shaft 11 and the second hinge shaft 21 are arranged. When the first hinge sleeve 31 is separated from the first hinge shaft 11, the second hinge sleeve 32 is stably connected to the second hinge shaft 21, ensuring that the second hinge sleeve 32 cannot be separated from the second hinge shaft 21. Alternatively, when the second hinge sleeve 32 is separated from the second hinge shaft 21, the first hinge sleeve 31 is stably connected to the first hinge shaft 11, ensuring that the first hinge sleeve 31 cannot be separated from the first hinge shaft 11, thereby improving the stability of the door body 300 installation and preventing the door body 300 from falling when the hinge shaft is switched.

[0056] Furthermore, the first connector 33 is an L-shaped connector that is bent away from the door body 300. One end of the first connector 33 is connected to the first hinge sleeve 31, and the other end is connected to the second hinge sleeve 32. The first connector 33 is configured as an L-shaped connector. While satisfying the switching hinge axis, the first connector 33 also lengthens the length of the rotating arm 3 to increase the opening angle of the door body 300.

[0057] The second connector 34 is an L-shaped connector, with one end connected to the first hinge sleeve 31 and the other end connected to the door body 300. Specifically, the first plate of the second connector 34 is connected to the side of the door body 300. When the door body 300 is open, the second connector 34, the first connector 33, and the first hinge sleeve 31 do not interfere with the front panel 200. Furthermore, the arrangement of the first connector 33 and the second connector 34 allows the door body 300 to open to a wider angle, making it easier to access clothing.

[0058] In this embodiment, the first opening 311 and the second opening 321 are both trumpet-shaped, so that the first hinge shaft 11 can be smoothly inserted into the first hinge sleeve 31 , or the second hinge shaft 21 can be smoothly inserted into the second hinge sleeve 32 .

[0059] This embodiment also provides a clothes processing device, which can be a drum-type washing machine, dryer or washer-dryer. The clothes processing device includes an inner drum 100, a front plate 200, a door body 300 and the above-mentioned hinge structure, the first hinge shaft 11 is installed on the inner drum 100, the second hinge shaft 21 is installed on the front plate 200, and the rotating arm 3 is installed on the door body 300 (refer to Figure 1 and Figure 2 ).

[0060] When the door body 300 is in the open state, the second hinge sleeve 31 is rotatably connected to the second hinge shaft 21, and the first hinge sleeve 31 is separated from the first hinge shaft 11; when the door body 300 is in the closed state, the first hinge sleeve 31 is rotatably connected to the first hinge shaft 11, and the second hinge sleeve 32 is separated from the second hinge shaft 21; when switching the hinge shaft, the second hinge sleeve 32 will be separated from the second hinge shaft 21 only after the first hinge sleeve 31 is stably connected to the first hinge shaft 11 to ensure that they will not separate, or the first hinge sleeve 31 will be separated from the first hinge shaft 11 only after the second hinge sleeve 32 is stably connected to the second hinge shaft 21 to ensure that they will not separate, so that the door body 300 will not fall when switching the hinge shaft.

[0061] The clothing processing device provided in this embodiment can meet the requirements of a waterless design or an outer drum-free design between the inner and outer drums. It only requires sealing the inner drum 100, and there is no need to set two door bodies 300. This simplifies the structure of the clothing processing device and facilitates operation. In addition, the angle of the door body 300 when opened is large enough to facilitate taking and placing clothes, thereby improving user satisfaction.

[0062] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
