Description

Technical Field

[0001] This application relates to the field of washing machine technology, and more particularly to a drum washing machine. Background Technology

[0002] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. Front-loading washing machines are generally front-opening. The front of the washing machine has a loading port and a door. The door is hinged to the washing machine via a hinge assembly to open or close the loading port.

[0003] In related technologies, the hinge assembly includes a hinge seat and a hinge body that are rotatably connected. The hinge seat is connected to the cabinet, and the door is connected to the hinge body, thereby allowing the door to rotate relative to the cabinet to open or close the loading port. However, in practice, after the user fully opens the door, the front surface of the door will protrude too far outward in the opening direction, which increases the opening space required for the drum washing machine and is not conducive to the layout of the drum washing machine. Utility Model Content

[0004] This application discloses an embodiment of the washing machine technology that can reduce the door opening space required for a drum washing machine, thus facilitating the layout of the drum washing machine.

[0005] To achieve the above objectives, in a first aspect, embodiments of this application disclose a drum washing machine, comprising:

[0006] The box has a receiving cavity inside, and a clothing inlet and a hinge opening are formed on the front surface of the box. The clothing inlet is connected to the receiving cavity, and the hinge opening is located on one side of the clothing inlet.

[0007] A washing tub, wherein the washing tub is disposed within the receiving cavity, and the opening of the washing tub is correspondingly disposed to the loading port;

[0008] The door body, wherein the door body is provided with a first connecting part;

[0009] Hinge assembly, including:

[0010] A hinge seat, which is located within the receiving cavity and connected to the housing;

[0011] A hinge shaft, which is located within the receiving cavity and connected to the hinge seat;

[0012] The hinge body includes:

[0013] A rotating part, one end of which is rotatably connected to the hinge shaft, and a bent structure is formed on the rotating part to avoid the edge of the hinge opening when the rotating part rotates;

[0014] The second connecting part is connected to the first connecting part and extends out of the hinge opening. The second connecting part can drive the door to open or close the clothes opening.

[0015] A transition section, one end of which is connected to the other end of the rotating section, and the other end of which is connected to the second connecting section;

[0016] The second connecting portion is offset relative to the transition portion along a first direction, wherein the first direction is the direction from the front surface of the door body to the rear surface.

[0017] In this application, the hinge body includes a rotating part, a second connecting part, and a transition part. The two ends of the transition part are connected to the rotating part and the second connecting part, respectively. The rotating part is rotatably engaged with the hinge seat through the hinge shaft. The second connecting part is offset relative to the transition part along a first direction, which is the direction from the front surface of the door to the rear surface. Thus, when the door is closed, the second connecting part will be closer to the rear surface of the cabinet relative to the transition part. Compared with the technical solution where the door is connected to the transition part, this application connects the door to the second connecting part so that the door is closer to the rear surface of the cabinet when it is closed. In this way, when the door is fully opened, the front surface of the door will be further inward in the opening direction of the door, thereby reducing the opening space required for the drum washing machine and facilitating the layout of the drum washing machine.

[0018] In one alternative embodiment, the second connecting portion is arranged parallel to the transition portion.

[0019] This reduces the difficulty of connecting the door body to the second connecting part.

[0020] In one optional embodiment, the distance by which the second connecting portion is offset relative to the transition portion along the first direction is L1, and the thickness of the transition portion is T1, (L1 / T1) = 1 to 3.

[0021] If (L1 / T1) is less than 1, the second connecting part will be closer to the rear surface of the cabinet than the transition part when the door is closed, but the degree of proximity is small. Thus, when the door is fully opened, the front surface of the door will move inward less in the opening direction, reducing the required door opening space for the drum washing machine. This weakens the effect of facilitating the layout of the drum washing machine. If (L1 / T1) is greater than 3, the second connecting part and the transition part will be far apart, which will increase the processing difficulty of the hinge body. Furthermore, when the second connecting part and the transition part are far apart, the size of the connection structure between them (such as the connecting part described below) will be too large, which will reduce the torsional stiffness of the hinge body.

[0022] Therefore, in this embodiment, (L1 / T1) is controlled between 1 and 3, which allows the second connecting part to be at a suitable distance from the rear surface of the cabinet relative to the transition part when the door is closed. This facilitates the layout of the drum washing machine, does not increase the processing difficulty of the hinge body, and does not reduce the torsional stiffness of the hinge body.

[0023] In an optional embodiment, the hinge body further includes:

[0024] The connecting part has one end connected to the transition part and the other end connected to the second connecting part.

[0025] The second connecting part and the transition part can be connected by the connecting part, so that the second connecting part can rotate with the rotating part.

[0026] In one optional embodiment, the portion of the rotating part near the hinge axis is bent to form a first bent segment, the bent structure includes the first bent segment, the rotating part has a limiting structure, the limiting structure is disposed on the first bent segment, and the hinge seat can stop and limit the limiting structure in the direction of opening the door.

[0027] In this embodiment, the rotating part has a limiting structure. When the door is opened to its limit position, the hinge seat stops and limits the limiting structure in the direction of opening the door, thereby limiting the maximum angle at which the door can be opened. In this embodiment, the limiting structure is set on the first bending section of the rotating part. The first bending section is formed by bending the part of the rotating part near the hinge axis. That is, the first bending section bulges in the direction away from the hinge axis (from left to right in the figure). Therefore, the limiting structure is set on the first bending section and is relatively far away from the hinge axis. Thus, the hinge body needs to rotate a larger angle to cooperate with the hinge seat. This allows the door to rotate a larger angle with the hinge body, thereby increasing the opening angle of the door and making it easier for the user to put in or take out clothes.

[0028] In one optional embodiment, the maximum distance between the axes of the rotating part and the hinge axis in the second direction is L2, wherein the second direction is perpendicular to the first direction and the axis of the hinge axis, and the maximum distance between the axes of the rotating part and the hinge axis in the first direction is L3, 1≤

[0029] (L3 / L2)≤2.

[0030] Taking L3 as a constant, if (L3 / L2) is less than 1, it means that the size of L2 is too large. This will cause the rotating part to be too far away from the axis of the hinge, that is, the rotating part protrudes too far to the right. This may cause the rotating part to interfere with the hinge opening during rotation. If (L3 / L2) is greater than 2, it means that the size of L2 is too small. This will cause the rotating part to be less far away from the axis of the hinge, weakening the effect of increasing the opening angle of the door.

[0031] Therefore, in this embodiment, (L3 / L2) is controlled at 1 to 2, which allows the rotating part to be at a suitable distance from the axis of the hinge shaft. In this way, the rotating part will not interfere with the hinge opening during rotation, and the door can be guaranteed to have a large opening angle, making it convenient for users to put in or take out clothes.

[0032] In an alternative embodiment, the hinge body is a sheet metal part, and the second connecting portion is formed by stamping so that the second connecting portion is offset relative to the transition portion along the first direction.

[0033] In this embodiment, the hinge body is a sheet metal part, that is, the hinge body is made of metal material, so it has high structural strength; furthermore, the hinge body formed by the sheet metal part is smaller in size, which is conducive to the miniaturization design of the hinge body, thereby reducing the space occupied by the hinge body and facilitating the layout of the hinge components; in addition, the second connecting part has high strength and durability after being stamped and formed, and can withstand a large load.

[0034] In one optional embodiment, the second connecting part is provided with a positioning structure, and the door body is provided with a mating structure, wherein the positioning structure and the mating structure are positioned and mated.

[0035] In this embodiment, the second connecting part and the door body are positioned and fitted by a positioning structure and a fitting structure. Thus, when assembling the door body and the hinge body, it is only necessary to fit the positioning structure and the fitting structure together to complete the precise fit between the second connecting part and the door body. This avoids problems such as door shaking or incomplete closure caused by assembly errors, thereby simplifying the assembly difficulty between the hinge body and the door body.

[0036] In one alternative embodiment, the rotating part has a limiting structure, and the hinge seat includes:

[0037] A base, which is connected to the housing and to the hinge shaft;

[0038] The stop part has a first end connected to the seat body and is located on the movement path of the limiting structure so as to stop and limit the limiting structure when the door is opened to the limit position.

[0039] The second end of the stop portion is offset relative to the first end of the stop portion in a direction away from the limiting structure.

[0040] In this embodiment, the second end of the stop is offset relative to the first end of the stop in a direction away from the limiting structure. That is, the second end of the stop is offset relative to the first end of the stop in a direction that the limiting structure moves closer to the stop during the opening of the door. In this way, the hinge body needs to rotate a larger angle before the limiting structure will make contact with the stop. In other words, with the structure of this embodiment, the hinge body can rotate a larger angle to increase the opening angle of the door, making it easier for users to put in or take out clothes.

[0041] In one optional embodiment, the washing tub includes:

[0042] A first cylindrical body is disposed within the receiving cavity;

[0043] The second cylindrical body is disposed within the receiving cavity and is arranged side by side with the first cylindrical body in the horizontal direction;

[0044] The garment inlet includes:

[0045] The first garment inlet is provided corresponding to the opening of the first cylinder;

[0046] The second garment inlet is provided corresponding to the opening of the second cylinder;

[0047] The number of doors and hinge assemblies includes two. Each door is rotatably connected to the box body through its respective hinge assembly. The two doors respectively cooperate with the first garment inlet and the second garment inlet.

[0048] In this embodiment, the washing drum includes a first drum and a second drum that are spaced apart in the horizontal direction. The first drum and the second drum are two completely independent drums and are not connected. Therefore, the first drum and the second drum can operate independently to achieve zone washing. Zone washing can separate clothes with different washing requirements. For example, underwear and other intimate clothing and outerwear need to be washed separately to avoid cross-contamination and ensure the washing quality of the clothes.

[0049] Secondly, embodiments of this application also disclose a drum washing machine, comprising:

[0050] The box has a receiving cavity inside, and a clothing inlet is formed on the front surface of the box, which is connected to the receiving cavity;

[0051] A washing tub, wherein the washing tub is disposed within the receiving cavity, and the opening of the washing tub is correspondingly disposed to the loading port;

[0052] The door body, wherein the door body is provided with a first connecting part;

[0053] Hinge assembly, including:

[0054] A hinge seat, which is located within the receiving cavity and connected to the housing;

[0055] A hinge shaft, which is located within the receiving cavity and connected to the hinge seat;

[0056] A hinge body, one end of which is rotatably connected to the hinge shaft, and the other end of which has a second connecting portion connected to the first connecting portion;

[0057] The other end of the hinge body is recessed along a first direction to form the second connecting portion, wherein the first direction is the direction from the front surface of the door body to the rear surface.

[0058] In this application, the other end of the hinge body is recessed along the first direction to form a second connecting part. When the door is closed, the second connecting part will be closer to the rear surface of the cabinet. When the door is fully opened, the front surface of the door will be further in the opening direction, thereby reducing the opening space required for the drum washing machine and facilitating the layout of the drum washing machine.

[0077] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0078] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0079] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0080] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0081] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0082] In modern life, washing machines have become an essential household appliance. Washing machines include top-loading washing machines and front-loading washing machines. Front-loading washing machines are generally front-opening. The front of the washing machine has a loading port and a door. The door is hinged to the washing machine via a hinge assembly to open or close the loading port.

[0083] In the related technology (CN110042630B), the hinge assembly includes a hinge seat and a hinge body that are rotatably connected. The hinge seat is connected to the housing, and the door is connected to the hinge body, thereby allowing the door to rotate relative to the housing to open or close the loading port. The inventors discovered that the hinge body (the rotating arm of CN110042630B) of the related technology has a planar structure at the end away from the hinge axis. This planar structure is connected to the door. When the door is closed, the distance between the planar structure and the rear surface of the housing is relatively large. Therefore, after the door is connected to the planar structure, the door will be further forward. Thus, when the door is fully opened, the front surface of the door will be further outward in the opening direction. Obviously, this will increase the opening space required for the drum washing machine, which is not conducive to the layout of the drum washing machine.

[0084] This application provides a drum washing machine that reduces the door opening space required for the drum washing machine, thus facilitating the layout of the drum washing machine.

[0085] The drum washing machine provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0086] like Figures 1 to 9 As shown in the figure, this application discloses a drum washing machine, including:

[0087] The cabinet 100 has an internal cavity. The cabinet 100 forms the overall appearance of the drum washing machine, and the cavity within it is configured to house multiple components of the pulsator washing machine, such as the washing drum, electrical circuitry, drive components, and drainage components. The cabinet 100 can be rectangular for placement against a wall. Alternatively, it can be cylindrical to accommodate the circular components within the drum washing machine.

[0088] The front surface of the housing 100 has a clothes inlet 110 and a hinge opening 120. The clothes inlet 110 is connected to the receiving cavity, and the hinge opening 120 is located on one side of the clothes inlet 110. The clothes inlet 110 can be located on the front side of the housing 100, through which clothes can be put into the washing drum; the hinge opening 120 is used for the hinge body 330, described below, to pass through the housing 100 to connect with the door 200.

[0089] A washing drum (not shown in the figure) is disposed within a receiving cavity, with its opening corresponding to the loading port 110. The washing drum is used to wash clothes, which are inserted into the washing cavity through the opening on the drum for washing. For example, the washing drum includes an outer drum and an inner drum. The outer drum is disposed within the housing 100, and the inner drum is disposed within the outer drum and is rotatable relative to the outer drum and the housing 100.

[0090] The door body 200 has a first connecting portion 210 for connection with the second connecting portion 332 described below. For an example, please refer to [the provided text]. Figure 5 and Figure 6 The first connecting part 210 may include a connecting post, and the connecting post and the second connecting part 332 may be connected by fastening structures such as screws, bolts, and adhesive layers; of course, the first connecting part 210 may also be a snap-fit ​​part, in which case the first connecting part 210 is snap-fitted with the second connecting part 332 of the door body 200.

[0091] Hinge assembly 300, including:

[0092] The hinge seat 320 is located inside the receiving cavity and connected to the housing 100. The hinge seat 320 is the fixed part of the hinge assembly 300, which plays a supporting and positioning role and can provide an installation base for the hinge shaft 310.

[0093] The hinge shaft 310 is located within the receiving cavity and connected to the hinge seat 320. For example, the hinge shaft 310 can be connected to the hinge seat 320 by riveting, welding, threaded connection, interference fit, or other methods.

[0094] Hinge body 330, including:

[0095] The rotating part 331 has one end rotatably connected to the hinge shaft 310. A bent structure is formed on the rotating part 331 to avoid the edge of the hinge opening 120 when the rotating part 331 rotates, thereby reducing the opening size of the hinge opening 120. For example, one end of the rotating part 331 can form a winding unit around the hinge shaft 310, with the hinge shaft 310 passing through the winding unit; alternatively, a rotating hole can be formed at one end of the rotating part 331, with the hinge shaft 310 passing through the rotating hole.

[0096] The second connecting part 332 is connected to the first connecting part 210 and extends out of the hinge opening 120. The second connecting part 332 can drive the door 200 to open or close the clothes opening 110. In other words, the door 200 can rotate with the hinge body 330.

[0097] The transition section 333 has one end connected to the other end of the rotating section 331, and the other end of the transition section 333 is connected to the second connecting section 332.

[0098] The second connecting portion 332 is relative to the transition portion 333 along the first direction ( Figure 5The offset setting (indicated by the x-arrow line) is where the first direction is from the front surface of the door 200 to the rear surface. It should be noted that the front / rear surface of the door 200 refers to the surface of the door 200 located on its front / rear side when the door 200 is in the closed state.

[0099] In this application, the hinge body 330 includes a rotating part 331, a second connecting part 332, and a transition part 333. The two ends of the transition part 333 are respectively connected to the rotating part 331 and the second connecting part 332. The rotating part 331 is rotatably engaged with the hinge seat 320 via a hinge shaft 310. The second connecting part 332 is offset relative to the transition part 333 along a first direction, which is the direction from the front surface of the door body 200 to the rear surface. Thus, when the door body 200 is in the closed state, the second connecting part 332... The transition portion 333 is closer to the rear surface of the cabinet 100. Compared with the technical solution where the door 200 is connected to the transition portion 333, the present application connects the door 200 to the second connecting portion 332 so that the door 200 is closer to the rear surface of the cabinet 100 when it is closed. In this way, when the door 200 is fully opened, the front surface of the door 200 will be further inward in the opening direction of the door 200, thereby reducing the door opening space required for the drum washing machine and facilitating the layout of the drum washing machine.

[0100] Furthermore, if the second connecting portion 332 and the transition portion 333 are offset as a whole in the first direction, the transition portion 333 will interfere with the edge of the hinge opening 120 when the door 200 is in the closed state. This would require a larger hinge opening 120, which would not only weaken the structural strength of the front of the housing 100 but also worsen the seal between the door 200 and the housing 100. Therefore, this application only offsets the second connecting portion 332 in the first direction, while the transition portion 333 is not offset in the second direction. This prevents the transition portion 333 from interfering with the edge of the hinge opening 120 when the door 200 is in the closed state, and eliminates the need for a large hinge opening 120 to ensure the structural strength and sealing performance of the housing 100.

[0101] In one alternative embodiment, please refer to Figure 8 and Figure 9 The second connecting portion 332 is arranged parallel to the transition portion 333, which reduces the difficulty of connecting the door body 200 to the second connecting portion 332. Of course, the second connecting portion 332 may also be inclined relative to the transition portion 333, and this application does not limit this.

[0102] It should be noted that the first connecting part 210 can be connected to the front surface of the second connecting part 332, or the first connecting part 210 can be connected to the rear surface of the second connecting part 332.

[0103] In an optional embodiment, the distance by which the second connecting portion 332 is offset relative to the transition portion 333 along the first direction is L1, and the thickness of the transition portion 333 is T1, where (L1 / T1) = 1 to 3. For example, (L1 / T1) can be equal to 1.1, 1.2, 1.5, 1.6, 1.8, 2.1, 2.3, 2.5, 2.6, 2.9, etc., and this application does not impose any limitations on this.

[0104] If (L1 / T1) is less than 1, the second connecting part 332 will be closer to the rear surface of the cabinet 100 than the transition part 333 when the door 200 is closed, but the degree of proximity is small. Thus, when the door is fully opened, the front surface of the door will move inward less in the opening direction, reducing the required door opening space for the drum washing machine. This weakens the effect of the layout of the drum washing machine. If (L1 / T1) is greater than 3, the second connecting part 332 and the transition part 333 will be far apart, which will increase the processing difficulty of the hinge body 330. Moreover, when the second connecting part 332 and the transition part 333 are far apart, the size of the connection structure between them (such as the connecting part 334 described below) will be too large, which will reduce the torsional stiffness of the hinge body 330.

[0105] Therefore, in this embodiment, (L1 / T1) is controlled between 1 and 3, which enables the second connecting part 332 to be at a suitable distance from the transition part 333 to the rear surface of the cabinet 100 when the door 200 is in the closed state. This improves the layout of the drum washing machine without increasing the processing difficulty of the hinge body 330 or reducing the torsional stiffness of the hinge body 330.

[0106] In one alternative embodiment, please refer to Figure 8 The hinge body 330 also includes:

[0107] A connecting portion 334 is provided, with one end connected to the transition portion 333 and the other end connected to the second connecting portion 332. The connecting portion 334 connects the second connecting portion 332 and the transition portion 333, allowing the second connecting portion 332 to rotate with the rotating portion 331. For example, the connecting portion 334 may be inclined relative to the transition portion 333, or it may be perpendicular to the transition portion 333. It should be noted that when this embodiment is combined with the technical solution described below where the second connecting portion 332 is formed by stamping, the connecting portion 334 may be the bend between the second connecting portion 332 and the transition portion 333.

[0108] In one alternative embodiment, please refer to Figure 9The rotating part 331 is bent near the hinge shaft 310 to form a first bent section 3312. The bent structure includes the first bent section 3312. The rotating part 331 has a limiting structure 3311. The limiting structure 3311 is provided on the first bent section 3312. The hinge seat 320 can stop and limit the limiting structure 3311 in the direction of opening the door body 200.

[0109] In this embodiment, the rotating part 331 has a limiting structure 3311. When the door 200 is opened to its limit position, the hinge seat 320 stops and limits the limiting structure 3311 in the direction of opening the door 200, thereby limiting the maximum angle at which the door 200 can be opened. In this embodiment, the limiting structure 3311 is provided on the first bent section 3312 of the rotating part 331. The first bent section 3312 is formed by bending the part of the rotating part 331 near the hinge axis 310. That is, the first bent section 3312 is bent in a direction away from the hinge axis 310. Figure 9 The hinge body 330 is raised from left to right. Therefore, the limiting structure 3311 is set on the first bending section 3312 and will be relatively far away from the hinge axis 310. Thus, the hinge body 330 needs to rotate a larger angle to cooperate with the hinge seat 320. This allows the door body 200 to rotate a larger angle with the hinge body 330, thereby increasing the opening angle of the door body 200 and making it easier for users to put in or take out clothes.

[0110] In some embodiments, the portion of the rotating part 331 away from the hinge axis 310 is bent to form a second bent segment 3313. The second bent segment 3313 is connected to the first bent segment 3312. The bending structure includes the second bent segment 3313. The transition part 333 is connected to the end of the second bent segment 3313 away from the first bent segment 3312. The first bent segment 3312 and the second bent segment 3313 together avoid the edge of the hinge opening 120.

[0111] In one alternative embodiment, please refer to Figure 9 The axes of the rotating part 331 and the hinge shaft 310 are in the second direction ( Figure 9 The maximum distance in the left and right directions of the view is L2, where the second direction is perpendicular to the first direction. Figure 9 The maximum distance between the rotating part 331 and the axis of the hinge shaft 310 in the first direction is L3, where 1 ≤ (L3 / L2) ≤ 2. For example, (L3 / L2) can be 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, etc., and this application does not limit this.

[0112] Taking L3 as a constant, if (L3 / L2) is less than 1, it means that the size of L2 is too large. This will cause the rotating part 331 to be too far away from the axis of the hinge shaft 310, that is, the rotating part 331 protrudes too far to the right. This may cause the rotating part 331 to interfere with the hinge opening 120 during rotation. If (L3 / L2) is greater than 2, it means that the size of L2 is too small. This will cause the rotating part 331 to be less far away from the axis of the hinge shaft 310, weakening the effect of increasing the opening angle of the door 200.

[0113] Therefore, in this embodiment, (L3 / L2) is controlled at 1 to 2, which allows the rotating part 331 to be at a suitable distance away from the axis of the hinge shaft 310. In this way, the rotating part 331 will not interfere with the hinge opening 120 during rotation, and the door body 200 can be guaranteed to have a large opening angle, which is convenient for users to put in or take out clothes.

[0114] In an alternative embodiment, the hinge body 330 is a sheet metal part, and the second connecting portion 332 is formed by stamping so that the second connecting portion 332 is offset relative to the transition portion 333 in a first direction.

[0115] In this embodiment, the hinge body 330 is a sheet metal part, meaning it is made of metal, thus possessing high structural strength. Furthermore, the hinge body 330 formed from sheet metal is smaller in size, facilitating miniaturization and reducing the space occupied by the hinge body 330, which is beneficial for the layout of the hinge assembly 300. Additionally, the second connecting portion 332, after being stamped, has high strength and durability, capable of withstanding large loads. Of course, the hinge body 330 can also be an injection molded part; this application does not impose any limitations on this.

[0116] In one alternative embodiment, please refer to Figure 7 The second connecting part 332 is provided with a positioning structure 3321, and the door body 200 is provided with a mating structure 130. The positioning structure 3321 and the mating structure 130 are positioned and mated. For example, the positioning structure 3321 can be a positioning hole or a positioning post, and the mating structure 130 can be a positioning post or a positioning hole.

[0117] In this embodiment, the second connecting part 332 and the door body 200 are positioned and engaged by the positioning structure 3321 and the mating structure 130. Thus, when assembling the door body 200 and the hinge body 330, it is only necessary to engage the positioning structure 3321 and the mating structure 130 to complete the precise engagement between the second connecting part 332 and the door body 200, avoiding problems such as door body 200 shaking or not closing properly due to assembly errors, thereby simplifying the assembly difficulty between the hinge body 330 and the door body 200.

[0118] In one alternative embodiment, please refer to Figures 6 to 8The rotating part 331 has a limiting structure 3311, and the hinge seat 320 includes:

[0119] The base 321 is connected to the housing 100 and to the hinge shaft 310.

[0120] The stop part 322 has its first end connected to the seat 321. The stop part 322 is located on the movement path of the limiting structure 3311 so as to stop and limit the limiting structure 3311 when the door 200 is opened to the limit position, thereby limiting the maximum angle that the door 200 can open.

[0121] The second end of the stop portion 322 is offset relative to the first end of the stop portion 322 in a direction away from the limiting structure 3311.

[0122] The specific working process is as follows: during the opening of the door 200, the hinge body 330 will rotate relative to the hinge shaft 310, and the limiting structure 3311 on the hinge body 330 will gradually approach the stop part 322 of the hinge seat 320. When the limiting structure 3311 contacts the stop part 322, the hinge body 330 stops rotating, and the door 200 opens to the maximum angle.

[0123] In this embodiment, the second end of the stop 322 is offset relative to the first end of the stop 322 in a direction away from the limiting structure 3311. That is, the second end of the stop 322 is offset relative to the first end of the stop 322 in a direction that the limiting structure 3311 moves closer to the stop 322 during the opening of the door 200. In this way, the hinge body 330 needs to rotate a larger angle before the limiting structure 3311 will make contact with the stop 322. In other words, with the structure of this embodiment, the hinge body 330 can rotate a larger angle to increase the opening angle of the door 200, making it easier for the user to put in or take out clothes.

[0124] In one alternative embodiment, the washing tub includes:

[0125] A first tub is disposed within a receiving cavity for washing clothes. For example, the first tub includes a first outer tub and a first inner tub. The first outer tub is disposed within a housing 100, and the first inner tub is disposed within the first outer tub and is rotatable relative to the first outer tub and the housing 100.

[0126] The second tub is disposed within the receiving cavity and arranged horizontally alongside the first tub. The second tub is used for washing clothes. For example, the second tub includes a second outer tub and a second inner tub. The second outer tub is disposed within the housing 100, and the second inner tub is disposed within the second outer tub and is rotatable relative to the second outer tub and the housing 100.

[0127] The 110 emergency call center includes:

[0128] The first garment inlet is set in accordance with the opening of the first cylinder. Here, the first garment inlet can be set on the front side of the box 100, and clothes can be put into the first cylinder through the first garment inlet.

[0129] The second garment inlet is provided in accordance with the opening of the second cylinder. The second garment inlet can be located on the front side of the box 100, and clothes can be put into the second cylinder through the second garment inlet.

[0130] The number of door bodies 200 and hinge assemblies 300 includes two. Each door body 200 is rotatably connected to the housing 100 through each hinge assembly 300. The two door bodies 200 are respectively engaged with the first garment opening and the second garment opening. That is to say, one door body 200 can open or close the first garment opening, and the other door body 200 can open or close the second garment opening.

[0131] In this embodiment, the washing drum includes a first drum and a second drum that are spaced apart in the horizontal direction. The first drum and the second drum are two completely independent drums and are not connected. Therefore, the first drum and the second drum can operate independently to achieve zone washing. Zone washing can separate clothes with different washing requirements. For example, underwear and other intimate clothing and outerwear need to be washed separately to avoid cross-contamination and ensure the washing quality of the clothes.

[0132] In one alternative embodiment, please refer to Figure 4 and Figure 5 Drum washing machines also include:

[0133] The fastener has a first end that passes through and connects to the second connecting portion 332, and a second end that is exposed on the side of the second connecting portion 332 facing away from the connecting portion. For example, the fastener may be a screw, bolt, etc.

[0134] Cover 400 is connected to hinge body 330 and covers fasteners, thus preventing fasteners from being exposed and reducing the risk of fastener corrosion.

[0135] In one alternative embodiment, please refer to Figure 7 and Figure 8 The cover 400 is provided with a hook 410 and the hinge body is provided with a stop part 335. The hook 410 and the stop part 335 are engaged and matched, so the assembly and disassembly of the cover 400 are relatively simple.

[0136] In one alternative embodiment, please refer to Figure 7 and Figure 8The hinge body has a through opening 336, and the stop part 335 is connected to the inner wall of the through opening 336. At least part of the hook 410 is located in the through opening 336. In this embodiment, the through opening 336 is used to accommodate the hook 410, which can avoid the hook 410 occupying a large space.

[0137] In one alternative embodiment, please refer to Figure 7 and Figure 8 The cover 400 has a protrusion, and the door 200 has a slot. The protrusion and the slot are inserted and matched, which can reduce the number of hooks 410, thereby reducing the difficulty of assembling the cover 400.

[0138] This application also discloses a drum washing machine, including:

[0139] The box 100 has a receiving cavity inside, and a clothing inlet 110 is formed on the front surface of the box 100, which is connected to the receiving cavity.

[0140] A washing drum is installed inside the receiving cavity, with the opening of the washing drum corresponding to the loading port 110.

[0141] The door body 200 has a first connecting part 210.

[0142] Hinge assembly 300, including:

[0143] Hinge seat 320, which is located in the receiving cavity and connected to the housing 100.

[0144] Hinge shaft 310 is located in the receiving cavity and is connected to hinge seat 320.

[0145] The hinge body 330 has one end rotatably connected to the hinge shaft 310, and the other end of the hinge body 330 has a second connecting part 332, which is connected to the first connecting part 210.

[0146] The other end of the hinge body 330 is recessed along the first direction to form a second connecting portion 332, thereby allowing the installation position of the door body 200 to move along the first direction, where the first direction is the direction from the front surface of the door body 200 to the rear surface. It should be noted that the other end of the hinge body 330 here refers to the end of the hinge body 330 away from the hinge axis 310. For example, the second connecting portion 332 can be formed in various ways, such as by stamping the other end of the hinge body 330 along the first direction; or by milling away part of the material from the other end of the hinge body 330 along the first direction, i.e., by thinning the thickness of the hinge body 330.

[0147] In this application, the other end of the hinge body 330 is recessed along the first direction to form a second connecting part 332. When the door 200 is in the closed state, the second connecting part 332 will be closer to the rear surface of the cabinet 100. Thus, when the door 200 is fully opened, the front surface of the door 200 will be further in the opening direction of the door 200, thereby reducing the opening space required for the drum washing machine and facilitating the layout of the drum washing machine.

[0148] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
