Description

Technical Field

[0001] The present application relates to the technical field of washing machines, and more specifically, to a washing machine door assembly and a washing machine. Background Art

[0002] With the development of technology, the functional design of washing machines has become more user-friendly. In scenarios where the user issues a voice command to indicate opening the door or the end of the washing program, the door body of the washing machine can automatically pop open.

[0003] In related technologies, if the degree of the washing machine door popping open is insufficient, a pop-up device is installed on the washing machine door. The pop-up device includes a pop-up member and a spring. When the door body of the washing machine is in a closed state, the spring is in a compressed state. After the washing machine door is unlocked, the spring pushes the pop-up member to act on the body of the washing machine to pop open the washing machine door body.

[0004] However, the washing machine door provided with a pop-up device has the problem of difficult assembly. Summary of the Utility Model

[0005] The purpose of the embodiments of the present application is to provide a washing machine door assembly and a washing machine, aiming to solve the technical problem of difficult assembly of the washing machine door in the prior art.

[0006] To achieve the above purpose, the technical solution adopted by the present application is:

[0007] In a first aspect, a washing machine door assembly is provided, including an outer door, an inner door, and a pop-up device. Among them,

[0008] A door body cavity is formed between the outer door and the inner door; the outer door includes a positioning structure, the positioning structure is located on the surface of the outer door facing the inner door, and protrudes inwardly into the door body cavity; a through hole is formed in the inner door, the inner door includes an annular first guiding structure, the first guiding structure is located on the outer periphery of the through hole on the surface of the inner door facing the outer door, and protrudes outwardly into the door body cavity;

[0009] The pop-up device includes an elastic structure and a pop-up structure. The pop-up structure includes a straight tube portion and a flanging portion. The straight tube portion forms an inner cavity, and the flanging portion surrounds the outer peripheral surface of the end of the straight tube portion close to the outer door. One end of the elastic structure contacts the axial center of the positioning structure on the surface of the outer door facing the inner door, and the other end contacts the top wall of the inner cavity; the positioning structure is circumferentially arranged outside the flanging portion;

[0010] The pop-up structure can move between a first position and a second position along the height direction of the positioning structure. When the pop-up structure is in the first position, the elastic structure is in the first compression state, and the straight cylinder part passes through the through hole and protrudes by a first height; when the pop-up structure is in the second position, the elastic structure is in the second compression state, and the straight cylinder part passes through the through hole and protrudes by a second height, and the upper surface of the flanging part contacts the end of the first guiding structure; the degree of compression in the first compression state is greater than that in the second compression state, and the first height is less than the second height.

[0011] The axial centers of the positioning structure, the through hole, the first guiding structure, the pop-up structure, and the elastic structure coincide.

[0012] The washing machine door assembly provided by the embodiment of the present application is applied to a washing machine. The first guiding structure plays a role of radial limiting and guiding for the straight cylinder part of the pop-up structure in the pop-up device. The positioning structure plays a role of radial limiting for the flanging part of the pop-up structure. The through hole is used for the pop-up structure to extend out, and the elastic structure is used to push the pop-up structure to pass through the through hole. When the washing machine door assembly is applied to the washing machine and is in the locked state, the pop-up structure passes through the through hole and protrudes by a first height and contacts the body of the washing machine. During the process of the washing machine door assembly switching from the locked state to the unlocked state, under the elastic force of the elastic structure, the pop-up structure extends out a greater distance from the through hole. Since one end of the pop-up structure contacts the body, the pop-up structure increases the distance between the washing machine door assembly and the body, that is, the washing machine door assembly is opened. As can be seen from the above, the pop-up device realizes the automatic pop-up of the washing machine door assembly when the washing machine door assembly switches from the locked state to the unlocked state.

[0013] In the washing machine door assembly provided by the embodiment of the present application, the outer door and the inner door need to be assembled. During the assembly process of the washing machine door assembly, before assembling the outer door and the inner door, one end of the elastic structure can be made to contact the axial center of the positioning structure on the surface of the outer door facing the inner door, the pop-up structure is buckled on the elastic structure, the elastic structure is located in the inner cavity of the pop-up structure, and at the same time, the flanging part of the pop-up structure is located in the positioning structure. In this setting method, the positioning structure plays a role of positioning for the elastic structure and a role of circumferential limiting for the flanging part, that is, the positioning structure plays a certain limiting role for the pop-up device, so that the pop-up device is pre-installed at an appropriate position on the outer door. When assembling the outer door and the inner door, there is no need to specifically pay attention to the alignment of the pop-up device and the inner door. After the outer door and the inner door are assembled, the straight cylinder part of the pop-up structure can pass through the through hole on the inner door. The entire assembly process does not require separately positioning the pop-up device and the through hole on the inner door, reducing the assembly difficulty of the washing machine door assembly. Especially for the case where the door assembly itself is heavy and is usually assembled flat, the method of pre-installing the pop-up device on the outer door greatly reduces the assembly difficulty.

[0014] In one technical solution, when the pop-up structure is in the first position, among the multiple sections of the washing machine door assembly along the central axis perpendicular to the pop-up structure, the section including the part of the pop-up structure in the door body cavity is the first section, wherein,

[0015] In all first sections, each first section includes at least one of a first guide structure and a positioning structure; or,

[0016] Among all the first sections, at least one first section includes a first guide structure, and at least one first section includes a positioning structure.

[0017] In this arrangement, the pop-up structure is under the guidance of at least one of the first guide structure and the positioning structure when it is in any position between the first position and the second position, thereby making the movement stability of the pop-up structure stronger.

[0018] In one technical solution, the positioning structure includes a supporting portion and a locking portion, and the supporting portion is connected to the locking portion; when the spring-opening structure is in the second position, the upper surface of the flange portion is still in contact with the lower surface of the locking portion.

[0019] In this arrangement, the support portion is located circumferentially outside the flange portion. As the pop-up structure moves circumferentially, the support portion acts as a radial limiter for the flange portion. In the second position, the retaining portion contacts the flange portion, thereby retaining the flange portion in the second position. During assembly, the retaining portion acts as an axial limiter for the pop-up structure, preventing it from detaching from the outer door, thereby facilitating installation. During use, in the second position, the pop-up structure contacts both the first guide structure and the retaining portion, respectively. This results in a relatively larger area where the pop-up structure is limited, thus ensuring greater positioning stability in the second position.

[0020] In one technical solution, the positioning structure includes at least a first positioning structure and a second positioning structure, the first positioning structure includes a first supporting portion and a first locking portion, the second positioning structure includes a second supporting portion and a second locking portion, and the first supporting portion and the second supporting portion are circumferentially symmetrical and spaced apart on the outer side of the straight tube portion;

[0021] The pop-up structure also includes a positioning portion, the middle portion of the positioning portion is connected to the outer peripheral edge of the flange portion, and the two ends of the positioning portion are respectively a first end and a second end, and the connection between the positioning portion and the flange portion extends to the first end and the second end along the first tangent direction, and the first tangent is the tangent of the curve of the outer periphery of the flange portion passing through the connection; a first notch is formed between the first end and the flange portion, and a second notch is formed between the second end and the flange portion, and one side edge of the first support portion is located in the first notch, and one side edge of the second support portion is located in the second notch.

[0022] In this setting method, the pop-up structure is limited relative to the positioning structure through the positioning part, so that the positioning structure limits the rotation direction of the pop-up structure to control the angular range of the pop-up structure rotating along the axial direction, thereby improving the stability of the pop-up structure during axial movement.

[0023] In one technical solution, a hollow area is provided in the middle of the support part.

[0024] In this setting method, the setting of the hollow part of the support part facilitates the integral molding of the support part, the positioning part and the outer door, which is convenient for production and manufacturing.

[0025] In one technical solution, the outer door further includes a guide cylinder, which is located on the surface of the outer door facing the inner door, and the guide cylinder protrudes inward toward the inner door in the door cavity; at least part of the elastic structure is located in the guide cylinder; the axial centers of the through hole and the guide cylinder coincide.

[0026] In this setting method, the guide cylinder and the first guiding structure respectively play a radial limiting role on the straight cylinder part from the inside and outside of the straight cylinder part, so that the pop-up structure has stronger stability during axial movement.

[0027] In one technical solution, the length of the guide cylinder located inside the inner cavity is greater than the distance between the first position and the second position.

[0028] In this setting method, during the entire stroke of the pop-up structure moving along the axial direction, the guide cylinder plays a radial limiting role on the pop-up structure from the inside of the pop-up structure, so that the pop-up structure has stronger stability during axial movement.

[0029] In one technical solution, there is a gap of 0.05 mm - 0.25 mm between the side wall of the straight cylinder part and the outer side wall of the guide cylinder.

[0030] In this setting method, there is a relatively small gap between the straight cylinder part and the guide cylinder. This relatively small gap enables the straight cylinder part to move more smoothly along the axial direction, and this relatively small gap enables the guide cylinder to have a relatively good limiting effect on the straight cylinder part.

[0031] In one technical solution, the top surface of the straight cylinder part is spherical.

[0032] In this setting method, the surface of the straight cylinder part in contact with the fuselage is spherical, so as to reduce the friction between the straight cylinder part and the fuselage and reduce the wear of the straight cylinder part.

[0033] In one technical solution, the outer door further includes a first reinforcing rib, which is located at the axial center of the positioning structure on the surface of the outer door, and the top surface of the first reinforcing rib is perpendicular to the top surface of the elastic structure; one end of the elastic structure contacts the first reinforcing rib.

[0034] In this setting method, the first reinforcing rib plays a supporting role for the elastic structure, and the first reinforcing rib provides a plane perpendicular to the central axis of the elastic structure for the elastic structure to reduce the possibility of the bottom surface of the elastic structure tilting.

[0035] In one technical solution, the first reinforcing rib is connected to the inner wall of the guiding cylinder.

[0036] In this setting method, the first reinforcing rib is connected to the guiding cylinder, thereby strengthening the connection strength of the guiding cylinder on the outer door.

[0037] In one technical solution, the outer door further includes a second reinforcing rib, and the second reinforcing rib avoids the elastic opening structure and is connected to the outer wall of the guiding cylinder.

[0038] In this setting method, the second reinforcing rib strengthens the connection strength of the guiding structure on the outer door.

[0039] In one technical solution, the outer door further includes a protrusion, the protrusion is located in the door body cavity, and the protrusion is located at the axial center of the positioning structure on the outer door, and one end of the elastic structure is sleeved outside the protrusion.

[0040] In this setting method, the protrusion plays a limiting role for one end of the elastic structure, and can reduce the radial sway of the elastic structure.

[0041] In a second aspect, a washing machine is provided, including a body and a washing machine door assembly provided in any of the above technical solutions, and the washing machine door assembly is hinged to the body.

[0042] The washing machine provided by the embodiment of the present application includes the washing machine door assembly provided by the above technical solution. Therefore, the washing machine at least includes all the beneficial effects of the above washing machine door assembly, which will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0074] First Embodiment

[0075] As Figures 1 to 3 shown, an embodiment of the present application provides a washing machine door assembly 1, and the washing machine door assembly 1 includes an outer door 10, an inner door 20, and a pop-up device 30. The washing machine door assembly 1 is applied to a washing machine, and the washing machine door assembly 1 is hinged to the body of the washing machine. An articulated area 24 may be provided at one edge area of the washing machine door assembly 1 in the width direction, and a locking area may be provided at the other edge area. The articulated area 24 can be used to install a hinge so that the washing machine door assembly 1 is hinged to the body through the hinge; the locking area can be used to install a locking structure so that the washing machine door assembly 1 is locked to the body through the locking structure. When the washing machine door assembly 1 is locked to the body through the locking structure, the washing machine door assembly 1 is in a locked state; when the program runs to an end, the locking structure between the washing machine door assembly 1 and the body is unlocked, and the washing machine door assembly 1 is in an unlocked state. In Figure 1 this case, two articulated areas 24 are provided on one side of the inner door 20 in its width direction, and the two articulated areas 24 are spaced apart in the length direction of the inner door 20. The number of the pop-up devices 30 can be one or more. When the number of the pop-up devices 30 is one, the pop-up device 30 can be provided in the middle area of the outer door 10 along the length direction. When the number of the pop-up devices 30 is multiple, such as two, three, four or more, the multiple pop-up devices 30 are spaced apart along the length direction of the outer door 10.

[0076] It is worth noting that when the washing machine door assembly 1 is applied to a washing machine, when the washing machine is in a use state, the length directions of the inner door 20 and the outer door 10 are both longitudinal (vertical direction), the width directions of the inner door 20 and the outer door 10 are both transverse (such as left and right directions), and the thickness directions of the inner door 20 and the outer door 10 are both directions perpendicular to the length direction and perpendicular to the width direction.

[0077] The ejector 30 can be arranged on the side of the washing machine door assembly 1 where the hinge area 24 is provided, and the ejector 30 can be arranged in the area between the two hinge areas 24. In Figures 1 to 3 In the shown washing machine door assembly 1, the number of ejectors 30 is one, and the ejector 30 is located between the two hinge areas 24 in the length direction of the outer door 10. It should be noted that the washing machine door assembly 1 can rotate relative to the body around the rotation axis W. In the width direction of the outer door 10, the ejector 30 is located between the rotation axis W and the locking area. Exemplarily, in Figure 3 the shown direction, the width direction of the washing machine door assembly 1 is the left-right direction, the hinge area 24 is located on the left side of the washing machine door assembly 1, then the locking area is located on the right side of the washing machine door assembly 1, the rotation axis W is located on the left side of the washing machine door assembly 1, and the ejector 30 is located on the right side of the rotation axis W. In this setting method, since the ejector 30 is arranged on the same side as the hinge area 24 in the width direction of the washing machine door assembly 1, and the ejector 30 is located between the two hinge areas 24 in the length direction of the washing machine door assembly 1, compared with arranging the ejector 30 in the locking area, arranging the ejector in the hinge area 24 can be closer to the rotation axis W, so that during the process of the washing machine door assembly 1 being ejected, the ejector 30 only needs to extend a relatively small second height to drive the washing machine door assembly 1 to rotate a relatively large angle.

[0078] In the washing machine door assembly 1 provided in the embodiment of the present application, the inner door 20 is installed on one side of the outer door 10 in the thickness direction. In the state where the washing machine door assembly 1 is connected to the body of the washing machine, the inner door 20 is closer to the body of the washing machine than the outer door 10, and the outer door 10 is farther from the body of the washing machine than the inner door 20. When the washing machine door assembly 1 is locked to the body, the outer door 10 is a part of the outer surface of the washing machine.

[0079] The outer door 10 is connected to the inner door 20. Exemplarily, the outer door 10 and the inner door 20 can be connected by one or more methods such as bolt connection, snap connection, and adhesive bonding. After the outer door 10 and the inner door 20 are connected, the relative positions of the outer door 10 and the inner door 20 remain unchanged.

[0080] Figure 4 is Figure 3 a cross-sectional view along the A-A direction, Figure 5 is Figure 4 an enlarged view of the C position in Figure 5 As shown, a door body cavity 40 is formed between the outer door 10 and the inner door 20, that is, after the outer door 10 and the inner door 20 are connected, there is a certain space between the outer door 10 and the inner door 20, and this space is the door body cavity 40.

[0081] The outer door 10 includes a positioning structure 12 which is located on the surface of the outer door 10 facing the inner door 20 and protrudes inwardly towards the inner door 20 in the door body cavity 40. A through hole 22 is formed in the inner door 20. The inner door 20 includes an annular first guiding structure 23 which is located on the outer periphery of the through hole 22 on the surface of the inner door 20 facing the outer door 10 and protrudes outwardly towards the outer door 10 in the door body cavity 40.

[0082] The ejector 30 includes an elastic structure 32 and an ejecting structure 31. The ejecting structure 31 is in the shape of a straw hat and includes a straight cylinder portion 311 and a flanging portion 312. The straight cylinder portion 311 forms an inner cavity 313. The flanging portion 312 surrounds the outer peripheral surface of the end of the straight cylinder portion 311 near the outer door 10. One end of the elastic structure 32 contacts the axial center of the positioning structure 12 on the surface of the outer door 10 facing the inner door 20, and the other end enters the inner cavity 313 through the opening of the straight cylinder portion and contacts the top wall of the inner cavity 313.

[0083] The positioning structure 12 is circumferentially arranged outside the flanging portion 312. The axial centers of the positioning structure 12, the through hole 22, the first guiding structure 23, the ejecting structure 31 and the elastic structure 32 coincide, that is, the positioning structure 12, the through hole 22, the first guiding structure 23, the ejecting structure 31 and the elastic structure 32 are coaxially arranged.

[0084] During the assembly of the washing machine door assembly provided in the embodiment, the elastic structure 32 can be placed in the inner cavity 313 of the ejecting structure 31, and the flanging portion 312 of the ejecting structure 31 can be located in the positioning structure 12. In another assembly process, the elastic structure 32 can also be placed in the positioning structure 12 first, and then the ejecting structure 31 can be buckled outside the elastic structure 32 so that one end of the elastic structure 32 enters the inner cavity 313 of the straight cylinder portion 311 of the ejecting structure 31. In this setting method, the positioning structure 12 plays a radial limiting role on the flanging portion 312, that is, the positioning structure 12 plays a certain radial limiting role on the ejector 30 so that the ejector 30 is pre-installed on the outer door 10. After the outer door 10 and the inner door 20 are assembled, the straight cylinder portion 311 of the ejecting structure 31 can pass through the through hole 22, and there is no need to separately position the straight cylinder portion 311 of the ejecting structure 31 and the through hole 22, reducing the positioning steps between the ejecting structure 31 and the through hole 22 and lowering the assembly difficulty of the washing machine door assembly 1.

[0085] The elastic structure 31 can move between a first position and a second position along the height direction of the positioning structure 12. When the elastic structure 31 is in the first position, the elastic structure 32 is in a first compressed state, and the elastic structure 31 protrudes from the through hole 22 by a first height; when the elastic structure 31 is in the second position, the elastic structure 32 is in a second compressed state, and the elastic structure 31 protrudes from the through hole 22 by a second height. The degree of compression in the first compressed state is greater than that in the second compressed state, and the first height is less than the second height.

[0086] The two end faces of the elastic structure 32 are respectively referred to as the positioning end face and the moving end face. The positioning end face contacts the outer door 10, and the moving end face contacts the top wall of the inner cavity 313 of the elastic structure 31. During the axial movement of the elastic structure 31, the position of the positioning end face remains unchanged, and the moving end face moves with the elastic structure 31, so that the distance between the positioning end face and the moving end face changes, and thus the compression amount of the elastic structure 32 changes.

[0087] When the washing machine door assembly is applied to a washing machine, the first position is the position where the elastic structure 31 is located when the washing machine is in the closed state, and the second position is the position where the elastic structure 31 is located when the washing machine is in the open state (and the ejector 30 is not in contact with the body). When the washing machine is in the closed state and the washing machine door assembly is in the locked state, the straight cylinder portion 311 of the elastic structure 31 abuts against the body, and the washing machine door assembly and the body are locked under the action of the locking structure of the washing machine, so that the relative positions of the inner door 20, the outer door 10 and the body in the washing machine door assembly remain unchanged. The elastic structure 31 abuts against the body, and there is a gap between the body and the inner door 20 in the axial direction of the elastic structure 31 in the closed state. This gap is called the first gap. The first gap between the body and the inner door 20 is equal to the height at which the elastic structure 31 protrudes from the through hole 22. The larger the first gap between the body and the inner door 20, the greater the height at which the elastic structure 31 protrudes from the through hole 22, so that the elastic structure 31 can abut against the body. The body limits the elastic structure 31 to the first position, and the elastic structure 31 makes the elastic structure 32 in the first compressed state. During the process of the washing machine door assembly switching from the locked state to the unlocked state, the locking structure of the washing machine is unlocked, and the moving end face of the elastic structure 32 moves away from the outer door 10 under the action of its own elastic force, thereby pushing the straight cylinder portion 311 of the elastic structure 31 to move from the first position to the second position. Since the position of the body remains unchanged, when the height at which the elastic structure 31 extends out of the through hole 22 is greater than the first gap, the washing machine door assembly rotates relative to the body, thereby realizing the automatic opening of the washing machine door assembly.

[0088] When the washing machine is in the door-open state (and the ejector 30 is not in contact with the body), the flanging portion 312 of the ejection structure 31 contacts the end face of the first guiding structure 23. The first guiding structure 23 has a force acting on the flanging portion 312 of the ejection structure 31 in the direction approaching the outer door 10, while the elastic structure 32 exerts a force on the straight cylinder portion 311 of the ejection structure 31 in the direction away from the outer door 10. Under the combined action of the elastic structure 32 and the first guiding structure 23, the ejection structure 31 is limited to the second position. During the movement of the ejection structure 31 from the first position to the second position, the moving end face of the elastic structure 32 moves in the direction away from the positioning end face, that is, the compression amount of the elastic structure 32 gradually decreases. When the ejection structure 31 is in the second position, the compression amount of the elastic structure 32 is the second compression amount, and the second compression amount is less than the first compression amount.

[0089] As Figure 6As shown in the figure, in the washing machine door assembly, the height of the door body cavity 40 is H1, and H1 is the distance between the side surface of the inner door 20 facing the outer door 10 and the side surface of the outer door 10 facing the inner door 20. The thickness of the inner door 20 is H2, then the height of the through hole 22 is H2, the height of the first guiding structure 23 is H3, the height of the elastic opening structure 31 is H4, the height of the flanging portion 312 is H5, and the height of the straight cylinder portion 311 is H4 - H5. The first gap is H6. It should be noted that the above heights and thicknesses are all dimensions in the axial direction of the straight cylinder portion 311. The height H4 of the elastic opening structure 31 > H2 + H3 + H5 + H6 (to prevent the elastic opening structure 31 from being too short to extend out of the door body cavity 40), and H4 ≤ H1 + H2 + H6 (to prevent the elastic opening structure 31 from being too long to close the door). That is to say, the height of the elastic opening structure 31 is greater than the sum of the height of the through hole 22, the height of the first guiding structure 23, the height of the flanging portion 312 and the first gap, and the height of the elastic opening structure 31 is less than or equal to the sum of the height of the door body cavity 40, the height of the through hole 22 and the first gap. Since H4 > H2 + H3 + H5 + H6, when the washing machine is in the closed state, there is a gap H7 (not shown in the figure) between the flanging portion 312 and the end surface of the first guiding structure 23, and H7 = H4 - (H2 + H3 + H5 + H6). In the closed state, the elastic opening structure 31 is in the first position, and the elastic structure 32 is in the first compression amount. At this time, the length (the distance between the moving end surface and the positioning end surface) of the elastic structure 32 is H8 (not shown in the figure). When the elastic opening structure 31 is in the second position, the elastic structure 32 is in the first compression amount. At this time, the height of the elastic structure is H9 (not shown in the figure). When the elastic opening structure 31 is in the first position, the gap between the flanging portion 312 and the first guiding structure 23 is H7. When the elastic opening structure 31 is in the second position, the flanging portion 312 contacts the first guiding structure 23, that is, the distance is zero. Then the moving distance of the elastic opening structure 31 from the first position to the second position is H7. When the elastic structure 32 changes from the first compression amount to the second compression amount, the length change of the elastic structure 32 is H7.

[0090] In one example, the inner door 20 includes an inner door body 21, and a through hole 22 is formed on the inner door body 21. The first guiding structure 23 and the inner door body 21 can be an integral structure and are manufactured by an integral molding process.

[0091] In one example, the first guiding structure 23 can be an annular columnar structure. In another example, the first guiding structure 23 can be an annular columnar structure, and an outer flanging is arranged on the end surface of the first guiding structure 23 close to the outer door 10 extending radially outward. The arrangement of the outer flanging increases the contact area between the first guiding structure 23 and the flanging portion 312 of the elastic opening structure 31 in the ejector 30, and improves the limiting effect of the first guiding structure 23 on the elastic opening structure 31.

[0092] In an exemplary embodiment, the through hole 22 is a round hole, and the hollow cavity in the first guiding structure 23 for the straight tube portion 311 to pass through is a round hole. The straight tube portion 311 is a cylindrical structure with a blind hole, the blind hole is a round hole, the blind hole of the straight tube portion 311 forms the inner cavity of the straight tube portion 311, and the flanging portion 312 is an annular structure.

[0093] The outer diameter of the straight tube portion 311 is slightly smaller than the inner diameter of the through hole 22 and slightly smaller than the inner diameter of the hollow cavity of the first guiding structure 23. Such a setting enables the straight tube portion 311 to move relative to the inner door 20 so that the straight tube portion 311 can pass through the hollow cavity in the first guiding structure 23 and through the through hole 22, so that the straight tube portion 311 can extend to the outside of the door body cavity 40.

[0094] The straight tube portion 311 is used to extend a certain distance from the through hole 22 to abut against the body of the washing machine, so that the washing machine door assembly rotates relative to the body, so that the washing machine door assembly has an automatic bouncing effect. Exemplarily, the diameter of the outer contour of the elastic structure 32 is smaller than the diameter of the inner cavity 313. In addition, when the elastic structure 32 is directly installed in the inner cavity 313 of the straight tube portion 311 and the diameter of the outer contour of the elastic structure 32 is slightly smaller than the diameter of the inner cavity 313, the straight tube portion 311 can also play a radial limiting role on the elastic structure 32, so that the elastic structure 32 changes more along the axial direction and less along the radial direction when deforming.

[0095] In one example, when the pop-up structure 31 is in the first position, that is, when the pop-up structure 31 projects out of the through hole 22 by a first height, among the multiple cross-sections of the washing machine door assembly perpendicular to the central axis of the pop-up structure 31, the cross-section including the part of the pop-up structure 31 in the door cavity 40 is the first cross-section. In one example, in all the first cross-sections, each first cross-section includes at least one of the first guiding structure 23 and the positioning structure 12. Exemplarily, when the central axis of the pop-up structure 31 extends in the vertical direction, the plane perpendicular to the central axis of the straight cylinder portion 311 is the horizontal plane. The cross-section of the washing machine door assembly perpendicular to the central axis of the straight cylinder portion 311 can also be referred to as the cross-section of the washing machine door assembly. It should be noted that the above cross-sections (including the first cross-section) are all virtual cross-sections. Along the axial direction of the pop-up structure 31, among all the cross-sections of the washing machine door assembly, at least some cross-sections include the pop-up structure 31, and part of the structure of the pop-up structure 31 is located in the door cavity 40. The cross-section including the pop-up structure 31 located in the door cavity 40 is called the first cross-section. In all the first cross-sections, each first cross-section includes at least one of the first guiding structure 23 and the positioning structure 12, that is to say, during the entire movement of the pop-up structure 31, there is the first guiding structure 23 or the positioning structure 12 to guide it. For a certain section of the pop-up structure 31, there may be both the first guiding structure 23 and the positioning structure 12 to guide it. Specifically, the first cross-section can include both the pop-up structure 31 and the first guiding structure 23 at the same time. In this case, the first guiding structure 23 plays a role of limiting and guiding the pop-up structure 31. The first cross-section can include both the pop-up structure 31 and the positioning structure 12 at the same time. The first cross-section can also include both the pop-up structure 31, the positioning structure 12 and the first guiding structure 23 at the same time. In one example, among the 100 first cross-sections of the washing machine door assembly distributed at axial intervals, 30 first cross-sections include both the pop-up structure 31 and the first guiding structure 23 at the same time, and 70 first cross-sections include both the pop-up structure 31 and the positioning structure 12 at the same time. In this setting method, the first guiding structure 23 plays a role of limiting and guiding the axial partial structure of the pop-up structure 31, and the positioning structure 12 plays a role of limiting and guiding the axial other partial structure of the pop-up structure 31. During the movement of the pop-up structure 31 between the first position and the second position, both the first guiding structure 23 and the positioning structure 12 play a role of limiting and guiding the pop-up structure 31.

[0096] In another example, among all the first cross-sections, at least one first cross-section includes a first guiding structure 23, and at least one first cross-section includes a positioning structure 12. That is to say, during the entire movement of the ejection structure 31, the top portion of the straight cylinder portion 311 of the ejection structure 31 is guided by the first guiding structure 23, and the bottom portion of the ejection structure 31 is guided by the positioning structure 12. For the middle portion of the ejection structure 31, it may not be guided by either the first guiding structure 23 or the positioning structure 12. Specifically, among all the first cross-sections, several first cross-sections simultaneously include the ejection structure 31 and the first guiding structure 23, several first cross-sections simultaneously include the ejection structure 31 and the positioning structure 12. In addition, there may be several first cross-sections that include the ejection structure 31 but do not include the first guiding structure 23 and the positioning structure 12. In one example, among 100 first cross-sections that are axially spaced apart in the washing machine door assembly, 10 first cross-sections simultaneously include the ejection structure 31 and the first guiding structure 23, 20 first cross-sections simultaneously include the ejection structure 31 and the positioning structure 12, and 70 first cross-sections include the ejection structure 31 but do not include the first guiding structure 23 and the positioning structure 12. In this setting method, during the movement of the ejection structure 31 between the first position and the second position, at least one of the first guiding structure 23 and the positioning structure 12 plays a role in limiting and guiding the ejection structure 31.

[0097] In the above two examples, during the movement of the ejection structure 31 between the first position and the second position, at least one of the first guiding structure 23 and the positioning structure 12 plays a guiding role for the ejection structure 31, that is, the ejection structure 31 has relatively good movement stability during the entire movement process.

[0098] In the above first example, since when the pop-up structure 31 is in the first position, the first cut surface includes at least one of the first guiding structure 23 and the positioning structure 12, it shows that when the pop-up structure 31 is in the first position, a partial area around the periphery of the pop-up structure 31 is surrounded by the first guiding structure 23, and another partial area is at least surrounded by the positioning structure 12. It can be inferred from the above that when the pop-up structure 31 is in the second position, a part of the straight cylinder portion 311 of the pop-up structure 31 is located inside the first guiding structure 23, and the upper surface of the flanging portion 312 of the pop-up structure 31 contacts the end of the first guiding structure 23, that is, the first guiding structure 23 is not surrounded outside the flanging portion 312, but the positioning structure 12 is surrounded outside the flanging portion 312. When in the first position and the second position, the positioning structure 12 is surrounded outside the flanging portion 312. Therefore, during the movement of the pop-up structure 31 between the first position and the second position, the flanging portion 312 is under the limiting and guiding action of the positioning structure 12. When the pop-up structure 31 is in the first position and the second position, the first guiding structure 23 is surrounded around the periphery of the straight cylinder portion 311. Therefore, during the movement of the pop-up structure 31 between the first position and the second position, the straight cylinder portion 311 is under the limiting and guiding action of the first guiding structure 23.

[0099] In the above second example, when the elastic opening structure 31 is in the first position, in all the first cutting planes, at least one first cutting plane includes the first guiding structure 23, and at least one first cutting plane includes the positioning structure 12. Therefore, it shows that when the elastic opening structure 31 is in the first position, a partial area around the periphery of the elastic opening structure 31 is surrounded by the first guiding structure 23, a partial structure is surrounded by the positioning structure 12, and there may also be a situation where the periphery of a partial structure is neither surrounded by the first guiding structure 23 nor by the positioning structure 12. When the axial length of the structure whose periphery is neither surrounded by the first guiding structure 23 nor by the positioning structure 12 is greater than or equal to the axial length of the flanging portion 312, it can be speculated from the above content that when the elastic opening structure 31 is in the second position, the outer side of a partial area of the straight barrel portion 311 is surrounded by the first guiding structure 23, and the outer side of the flanging portion 312 is neither surrounded by the first guiding structure 23 nor by the positioning structure 12. In this case, during the movement of the elastic opening structure 31 between the first position and the second position, it is always under the limiting and guiding action of the first guiding structure 23 and is under the limiting and guiding action of the positioning structure 12 within a certain distance. When the axial length of the structure whose periphery is neither surrounded by the first guiding structure 23 nor by the positioning structure 12 is less than the axial length of the flanging portion 312, it can be speculated from the above content that when the elastic opening structure 31 is in the second position, the outer side of a partial area of the straight barrel portion 311 is surrounded by the first guiding structure 23, and the outer side of a partial area of the flanging portion 312 is surrounded by the positioning structure 12. In this case, during the movement of the elastic opening structure 31 between the first position and the second position, it is simultaneously under the limiting and guiding actions of both the first guiding structure 23 and the positioning structure 12, and the movement stability is relatively high.

[0100] In summary, in the above first example and second example, since during the movement of the elastic opening structure 31 in the first example between the first position and the second position, the straight barrel portion 311 is always under the limiting and guiding action of the first guiding structure 23, and the flanging portion 312 is always under the limiting and guiding action of the positioning structure 12, the washing machine door assembly provided by the first example has a stronger limiting and guiding effect on the elastic opening structure 31, and the movement stability of the elastic opening structure 31 is stronger.

[0101] In one technical solution, the outer door 10 further includes a first reinforcing rib 14, which is located at the axial center of the surface positioning structure 12 on the surface of the outer door 10. The top surface of the first reinforcing rib 14 is perpendicular to the top surface of the elastic structure 32; one end of the elastic structure 32 contacts the first reinforcing rib 14. The first reinforcing rib 14 provides a plane perpendicular to the axis of the elastic structure 32 to support the bottom surface of the elastic structure 32, so that the bottom surface of the elastic structure 32 is perpendicular to the axis of the elastic structure 32, thereby reducing the possibility of the bottom surface of the elastic structure 32 tilting to a certain extent, so that the elastic structure 32 can deform more along the axial direction during the deformation process. It should be noted that the axial center of the surface positioning structure 12 on the outer door 10 is a partial area on the surface of the outer door 10, and this partial area includes the intersection of the surface of the outer door 10 and the axis of the positioning structure 12. The first reinforcing rib 14 and the outer door 10 are of an integral structure.

[0102] In some settings, the outer door 10 further includes a protrusion 13, which is located inside the door body cavity 40 and at the axial center of the positioning structure 12. One end of the elastic structure 32 is sleeved outside the protrusion 13. The protrusion 13 is located inside the elastic structure 32, which plays a radial limiting role for the elastic structure 32 and an axial guiding role.

[0103] In one setting, the outer door 10 does not include the first reinforcing rib 14, and the protrusion 13 protrudes from the surface of the outer door 10 towards the inner door 20 at the axial center of the positioning structure 12. The protrusion 13 can be in structural shapes such as cylindrical, frustum-shaped, conical, and straw hat-shaped.

[0104] In another setting, as Figure 5 shown, the outer door 10 includes a first reinforcing rib, and the outer door 10 further includes a protrusion 13, which is located at the center of the surface of the first reinforcing rib 14 facing the inner door 20 and protrudes towards the inner door 20. Exemplarily, Figure 5 the protrusion 13 in

[0105] Figure 5 is in a cylindrical structure in the bottom area close to the first reinforcing rib 14, and the protrusion 13 is in a frustum-shaped structure at the top away from the first reinforcing rib 14. The bottom of the elastic structure 32 is sleeved on the outer periphery of the protrusion 13. The pop-up structure 31 shown in

[0106] Figure 6 The pop-up structure 31 shown is in the first position, and the pop-up structure 31 protrudes from the through hole 22 by a first height, and the first height is the length of the gap between the body and the inner door 20 in the axial direction of the pop-up structure 31. When the washing machine door assembly 1 is applied to a washing machine and the washing machine door assembly 1 is in the closed state, the body contacts the top surface of the pop-up structure 31, and the body limits the pop-up structure 31 in the first position.

[0107] Figure 7 For Figure 3 A cross-sectional view of the washing machine door assembly 1 at B-B in Figure 8 For Figure 7 An enlarged view at D. Figure 7 The pop-up structure 31 shown is in the second position, and the upper surface of the flanging portion 312 contacts the end of the first guiding structure 23, and the end of the first guiding portion limits the flanging portion 312, so that the pop-up structure 31 is positioned in the second position under the combined action of the flanging portion 312, the first guiding portion and the elastic structure 32.

[0108] In one example, the first guiding structure 23 can be a cylindrical structure, and the end face of the end facing the outer door 10 is a continuous circular ring surface perpendicular to the axis of the pop-up structure 31. When the pop-up structure is in the second position, the upper surface of the flanging portion 312 contacts the circular ring surface of the first guiding structure 23.

[0109] Figure 9 A schematic structural diagram of the outer door 10, Figure 10 For Figure 9 An enlarged view at E in Figure 10 As shown, in another example, the outer contour of the first guiding structure 23 is cylindrical, and an avoidance notch 231 is provided at the end facing the outer door 10, and the avoidance notch 231 is used to accommodate a partial area of the positioning structure 12.

[0110] Figure 11 An assembly schematic diagram of the outer door 10 and the ejector 30, Figure 12 For Figure 11 An enlarged view at F in Figure 12 As shown, in one technical solution, the positioning structure 12 includes a support portion 121 and a locking portion 122, and the support portion 121 is connected to the locking portion 122; the number of the support portions 121 can be one or more.

[0111] The supporting part 121 can be a cylinder. The cross-section of the cylinder can be a complete circular ring, or the cylinder can have a notch, that is, the cross-section of the cylinder can be C-shaped. The inner wall of the cylinder (the wall surface facing the popping-up structure 31) is an arc surface, and the central angle of the arc surface can be greater than or equal to 180°, so that the cylindrical supporting part 121 covers a relatively larger range on the circumferential outer side of the popping-up structure 31, so as to play a better limiting role for the popping-up structure 31.

[0112] When the number of the supporting parts 121 is multiple, the supporting parts 121 can be arc-shaped plates. The multiple supporting parts 121 are arranged at intervals on the outer periphery of the popping-up structure 31, and the inner wall surfaces of the multiple supporting parts 121 are all arc surfaces. The centers of the inner wall surfaces of the respective supporting parts 121 coincide and the radii are equal.

[0113] One or more locking parts 122 can be arranged on one supporting part 121. The locking parts 122 can be arranged near the top of the supporting part 121. In one example, the locking parts 122 can be arranged on the top surface of the supporting part 121 and extend in the direction close to the straight cylinder part 311 (that is, extend in the direction close to the axial center line of the straight cylinder part 311), so that a partial area of the locking parts 122 is located above the flanging part 312. In another example, the locking parts 122 can be arranged at the top of the side surface of the supporting part 121 facing the straight cylinder part 311, so that at least a partial area of the locking parts 122 is located above the flanging part 312. The inner wall surface of the locking part 122 facing the popping-up structure 31 can be an annular surface or an arc surface. When the number of the locking parts 122 is multiple, the inner wall surfaces of the multiple locking parts 122 are all arc surfaces. The centers of the inner wall surfaces of the respective locking parts 122 coincide and the radii are equal.

[0114] The radius of the inner wall surface of the supporting part 121 is slightly larger than the radius of the outer wall surface of the flanging part 312, so that the flanging part 312 can move axially within the surrounding area of the supporting part 121, and the supporting part 121 plays a limiting role in the radial direction for the flanging part 312, and the supporting part 121 also plays a guiding role in the axial direction for the flanging part 312.

[0115] The radius of the inner wall surface of the locking part 122 is smaller than the radius of the outer wall surface of the flanging part 312 and larger than the radius of the outer wall surface of the straight cylinder part 311, so that the bottom surface of the locking part 122 can contact the top surface of the flanging part 312, so that the locking part 122 plays a limiting role for the flanging part 312.

[0116] In one example, the number of the supporting portions 121 and the locking portions 122 is plural. A guiding inclined surface is arranged in a region where the top surface of the locking portion 122 is close to the straight tube portion 311. The radius of the guiding inclined surface gradually decreases from the side close to the inner door 20 to the direction away from the outer door 10. The maximum radius of the guiding inclined surface is greater than or equal to the radius of the outer wall surface of the flanging portion 312, and the minimum radius of the guiding inclined surface is less than the radius of the outer wall surface of the flanging portion 312. During the assembly process, the bottom edge of the flanging portion 312 first contacts the guiding inclined surface. During the process that the elastic structure 31 moves towards the outer door 10, the flanging portion 312 moves along the guiding inclined surface and pushes the locking portion 122 in the direction away from the axial center, so that the supporting portion 121 deflects in the direction away from the axial center, so as to increase the distance between the plural locking portions 122, so that the flanging portion 312 moves through the surrounding area between the locking portions 122 to the lower part of the locking portion 122. When the flanging portion 312 moves to the lower part of the locking portion 122, the supporting portion 121 returns to its original state under the elastic action of its own material, so as to reduce the distance between the locking portions 122.

[0117] When the elastic structure is in the second position, the upper surface of the flanging portion 312 not only contacts the first guiding structure 23, but also contacts the lower surface of the locking portion 122. It should be noted that the upper surface of the flanging portion 312 is the surface of the flanging portion 312 facing the inner door 20, and the lower surface of the locking portion 122 is the surface of the locking portion 122 away from the inner door 20. When the first guiding structure 23 has an avoidance notch 231, at least part of the locking portion 122 can extend into the avoidance notch 231, so that at least part of the locking portion 122 is located in the avoidance notch 231, so that the lower surface of the locking portion 122 and the end surface of the first guiding structure 23 facing the outer door 10 are in the same plane, that is, part of the region of the upper surface of the flanging portion 312 contacts the first guiding structure 23 and part of the region contacts the locking portion 122. The setting of the avoidance notch 231 enables the first guiding structure 23 to play a certain limiting role on the locking portion 122, and accommodates the locking portion 122 in the avoidance notch 231, so that the structure of the first guiding structure 23 and the positioning structure 12 is more compact and the total occupied space is relatively smaller.

[0118] As Figure 13 shown, the top surface of the flanging portion 312 has a first area 312a and a second area 312b. The first area is used to contact the first guiding structure 23, and the second area is used to contact the locking portion 122. When the first guiding structure 23 has two relatively arranged avoidance notches 231, and a locking portion 122 is respectively arranged in the positioning structure 12 corresponding to each avoidance notch 231, the flanging portion 312 has two first areas and two second areas. When the flanging portion 312 shown in Figure 13 is in the second position, the flanging portion 312 contacts the first guiding structure 23 and the locking portion 122 at the same time.

[0119] In one example, the outer door 10 includes an outer door body 11. The positioning structure 12 and the outer door body 11 may be an integral structure, which is manufactured by an integral molding process. When the positioning structure 12 includes a support portion 121 and a locking portion 122, the support portion 121, the locking portion 122 and the outer door body 11 may be an integral structure.

[0120] In this setting, the support portion 121 is located on the outer circumferential side of the flanging portion 312. When the elastic opening structure 31 moves circumferentially, the support portion 121 plays a radial limiting role on the flanging portion 312. In the second position, the locking portion 122 contacts the flanging portion 312, thereby stopping the flanging portion 312 at the second position. During the assembly process, the locking portion 122 plays an axial limiting role on the elastic opening structure 31, that is, the elastic opening structure 31 will not disengage from the outer door 10, thus facilitating installation. During use, in the second position, the elastic opening structure 31 contacts the first guiding structure 23 and the locking portion 122 respectively, and the region where the elastic opening structure 31 is limited is relatively larger, that is, the positioning stability of the elastic opening structure 31 in the second position is stronger.

[0121] As Figure 12 shown, in one setting, the positioning structure 12 further includes a reinforcing portion 123. One side of the reinforcing portion 123 is connected to the outer side surface of the support portion 121 (the side surface away from the flanging portion 312), and the side surface of the reinforcing portion 123 away from the inner door 20 is connected to the outer door body 11. Exemplarily, the reinforcing portion 123, the support portion 121, the locking portion 122 and the outer door body 11 are an integral structure. As Figure 12 shown, in one specific embodiment, the reinforcing portion 123 is a triangular plate-like structure, and its side surface radially away from the support portion 121 is an inclined surface, and the distance between this inclined surface and the support portion 121 in the radial direction gradually increases in the direction away from the inner door 20. This setting facilitates the demolding operation during the production and manufacturing process of the integral molding of the positioning structure 12 and the outer door body 11, that is, it facilitates the production and processing of the outer door 10.

[0122] Please continue to refer to Figure 12 , in one technical solution, the top surface of the straight cylinder portion 311 is a spherical surface. In this setting, the surface of the straight cylinder portion 311 in contact with the fuselage is a spherical surface, so as to reduce the friction between the straight cylinder portion 311 and the fuselage and reduce the wear of the straight cylinder portion 311. It should be noted that the top surface of the straight cylinder portion 311 is the end face of the straight cylinder portion 311 at the end away from the outer door 10 along its own central axis direction.

[0123] In one technical solution, the positioning structure 12 includes at least two relatively spaced-apart portions of structures, and each portion includes a support portion 121 and a locking portion 122. As Figure 12As shown, the positioning structure 12 at least includes a first positioning structure and a second positioning structure. The first positioning structure includes a first supporting portion and a first locking portion, and the second positioning structure includes a second supporting portion and a second locking portion. The first supporting portion and the second supporting portion are circumferentially symmetric and spaced apart on the outer side of the straight cylinder portion 311. In an exemplary setting, both the first supporting portion and the second supporting portion are arc-shaped plate structures. The surface of the first supporting portion facing the second supporting portion is a first arc surface, and the surface of the second supporting portion facing the first supporting portion is a second arc surface. The first arc surface and the second arc surface are coaxially arranged and have the same radius. In a cross-section perpendicular to the axial direction of the elastic opening structure 31, the first arc surface presents as a first circular arc line, and the second arc surface presents as a second circular arc line. The centers of the first circular arc line and the second circular arc line coincide. In this way, it is more suitable for the circular flanging portion 312. The first supporting portion and the second supporting portion can limit the flanging portion 312 on the relatively two sides in the radial direction, and guide the movement of the flanging portion 312 in the axial direction. It should be noted that, in Figure 12 Among the two positioning structures 12 shown in, one is the first positioning structure, and the other is the second positioning structure. The supporting portion 121 in the first positioning structure is the first supporting portion, and the locking portion 122 in the first positioning structure is the first locking portion. The supporting portion 121 in the second positioning structure is the second supporting portion, and the locking portion 122 in the second positioning structure is the second locking portion.

[0124] The first locking portion is located at one end of the first supporting portion closer to the inner door 20, and the first locking portion is located on the side surface of the first supporting portion facing the second supporting portion. The second locking portion is located at one end of the second supporting portion closer to the inner door 20, and the second locking portion is located on the side surface of the second supporting portion facing the first supporting portion.

[0125] When the first guiding structure 23 has an avoidance notch 231, the first guiding structure 23 has two avoidance notches 231. One avoidance notch 231 accommodates the first locking portion, and the other avoidance notch 231 accommodates the second locking portion.

[0126] The first support part and the second support part are arranged at intervals, and the first locking part and the second locking part are arranged at intervals. During the assembly process of the elastic opening structure 31, the elastic opening structure 31 can be tilted at a certain angle so that the flanging part 312 of the elastic opening structure 31 can extend between the first support part and the second support part, and then the elastic opening structure 31 is returned to the upright position, so that the flanging part 312 is located on the side of the first locking part and the second locking part away from the outer door 10. In another assembly process of the elastic opening structure 31, although the radius of the inner wall enclosing area of the first locking part and the second locking part is smaller than the outer peripheral wall surface radius of the flanging part 312, since the end of the first support part away from the first locking part is integrally connected to the outer door body 11, the first support part undergoes a certain degree of tilting deformation under the extrusion of the flanging part 312. Similarly, the second support part undergoes a certain degree of deformation under the extrusion of the flanging part 312, so that the distance between the first locking part and the second locking part increases, so that the flanging part 312 can move through the space between the first locking part and the second locking part to between the first support part and the second support part. After the flanging part 312 completely passes through the space between the first locking part and the second locking part, the first locking part and the second locking part are no longer extruded by the flanging part 312, and the first support part and the second support part both return to their original states under the elastic action of their own materials, so that the first locking part and the second locking part move closer to each other and finally move to the side of the flanging part 312 away from the outer door 10 to play an axial limiting role for the flanging part 312.

[0127] In addition, since the first support part and the second support part are arranged at intervals, sliders can be placed between the first support part and the second support part during the production and manufacturing process of the outer door 10 to facilitate the formation of the first locking part and the second locking part. That is to say, the arrangement method of the first support part and the second support part at intervals improves the convenience during the production and processing of the outer door 10 and reduces the production and processing difficulty of the outer door 10.

[0128] As Figure 12 shown, the elastic opening structure 31 further includes a positioning part 314. The middle part of the positioning part 314 is connected to the outer peripheral edge of the flanging part 312. As Figure 14 shown, the two ends of the positioning part 314 are respectively a first end 314a and a second end 314b. As Figure 15As shown, the curve of the outer periphery of the flanging portion 312 has a tangent line at the connection, and this tangent line is the first tangent line. The connection between the positioning portion 314 and the flanging portion 312 extends along the first tangent line direction to the first end 314a and the second end 314b. The first end 314a and the second end 314b are located at both ends of the positioning portion 314 along the first tangent line direction. A first notch 315a is formed between the first end 314a and the flanging portion 312, and a second notch 315b is formed between the second end 314b and the flanging portion 312. One side edge of the first support portion 121 is located in the first notch 315a, and one side edge of the second support portion 121 is located in the second notch 315b. In this setting method, the elastic structure 31 is relatively limited in position through the positioning portion 314 and the positioning structure 12, so that the positioning structure 12 limits the rotation direction of the elastic structure 31 to control the angular range of the elastic structure 31 rotating along the axial direction, thereby improving the stability of the elastic structure 31 during the axial movement process.

[0129] The washing machine provided by the embodiment of the present application may be equipped with a voice control module or an automatic door opening function when the program ends. When the voice control module controls the locking structure between the body and the washing machine door assembly 1 to switch from the locked state to the unlocked state, under the elastic force of the elastic structure 32, the elastic structure 31 penetrates a greater distance from the through hole 22, so that the elastic structure 31 moves from the first position to the second position. Since one end of the elastic structure 31 contacts the body, the elastic structure 31 causes the washing machine door assembly 1 to rotate relative to the body around the rotation axis W. As can be seen from the above, the ejector 30 realizes the automatic ejection of the washing machine door assembly 1 during the switching process of the washing machine door assembly 1 from the locked state to the unlocked state.

[0130] In the washing machine door assembly 1 provided in the embodiment of the present application, the outer door 10 includes a positioning structure 12, which is located on the surface of the outer door 10 facing the inner door 20 and is circumferentially disposed outside the flange portion 312. Therefore, during assembly of the washing machine door assembly 1, the elastic structure 32 can be placed within the inner cavity 313 of the spring-opening structure 31, with the flange portion 312 of the spring-opening structure 31 positioned within the positioning structure 12. In this arrangement, the positioning structure 12 serves to limit the flange portion 312 in the circumferential direction. In other words, the positioning structure 12 serves to limit the spring-opener 30 to a certain extent. This allows the spring-opener 30 to be pre-installed on the outer door 10. Once the outer door 10 and the inner door 20 are assembled, the straight portion 311 of the spring-opening structure 31 can be passed through the through-hole 22. This eliminates the need to separately position the straight portion 311 of the spring-opening structure 31 with the through-hole 22, thereby reducing the number of positioning steps between the spring-opening structure 31 and the through-hole 22 and simplifying the assembly of the washing machine door assembly 1. When the positioning structure 12 includes a supporting portion 121 and a locking portion 122, the locking portion 122 is used to limit the pop-up structure 31 to the second position, that is, the locking portion 122 limits the axial movement distance of the pop-up structure 31, so that the pop-up structure 31 will not completely separate from the outer door 10. During the assembly of the washing machine door assembly 1, the elastic structure 32 can be first sleeved on the outer side of the spring limiting column, and then the pop-up structure 31 can be installed on the outer door 10 so that the flange portion 312 of the pop-up structure 31 is located below the locking portion 122 and one end of the elastic structure 32 extends into the inner cavity 313 of the pop-up structure 31. Finally, the inner door 20 is installed on the outer door 10. The assembly of the washing machine door assembly 1 can be completed without separately positioning the pop-up structure 30 and the through hole 22 of the inner door 20.

[0131] Second embodiment

[0132] An embodiment of the present application provides a washing machine door assembly 1. Similar to the washing machine door assembly 1 provided in the above first embodiment, the washing machine door assembly 1 provided in the embodiment of the present application includes an outer door 10, an inner door 20, and a pop-up device 30. A door body cavity 40 is formed between the outer door 10 and the inner door 20. The outer door 10 includes a positioning structure 12. The outer door 10 includes an outer door body 11. The positioning structure 12 and the outer door body 11 may be an integral structure and are manufactured by an integral molding process. The positioning structure 12 is located on the surface of the outer door 10 facing the inner door 20 and protrudes inwardly into the door body cavity 40 in the direction of the inner door 20. A through hole 22 is formed in the inner door 20. The inner door 20 includes an annular first guiding structure 23. The first guiding structure 23 is located on the outer periphery of the through hole 22 on the surface of the inner door 20 facing the outer door 10 and protrudes outwardly into the door body cavity 40 in the direction of the outer door 10. Specifically, the inner door 20 includes an inner door body 21. A through hole 22 is formed in the inner door body 21. The first guiding structure 23 and the inner door body 21 may be an integral structure and are manufactured by an integral molding process. The pop-up device 30 includes an elastic structure 32 and a pop-up structure 31. The pop-up structure 31 is in the shape of a straw hat and includes a straight tube portion 311 and a flanging portion 312. The straight tube portion 311 forms an inner cavity 313. One end of the elastic structure 32 contacts the axial center of the positioning structure 12 on the surface of the outer door 10 facing the inner door 20, and the other end contacts the top wall of the inner cavity 313. The positioning structure 12 is circumferentially arranged outside the flanging portion 312. The axial centers of the positioning structure 12, the through hole 22, the first guiding structure 23, the pop-up structure 31, and the elastic structure 32 coincide. The pop-up structure 31 can move between a first position and a second position along the height direction of the positioning structure 12. In the first position, the elastic structure 32 is in a first compressed state, and the pop-up structure 31 protrudes from the through hole 22 by a first height. In the second position, the elastic structure 32 is in a second compressed state, and the pop-up structure 31 protrudes from the through hole 22 by a second height. The degree of compression in the first compressed state is greater than that in the second compressed state, and the first height is less than the second height.

[0133] Differently from the washing machine door assembly 1 provided in the above first embodiment, as Figure 16 shown, in the washing machine door assembly 1 provided in the embodiment of the present application, the outer door 10 includes an outer door body 11. The outer door 10 further includes a guiding cylinder 50. The guiding cylinder 50 is located on the surface of the outer door 10 facing the inner door 20. The outer door body 11 and the guiding cylinder 50 are an integral structure. As Figure 17As shown, the guiding cylinder 50 protrudes towards the inner door 20 and is arranged in the door cavity 40; at least part of the elastic structure 32 is located in the guiding cylinder 50; the axial centers of the through hole 22 and the guiding cylinder 50 coincide. The radius of the outer contour surface of the elastic structure 32 is less than or equal to the radius of the inner wall of the guiding cylinder 50, the radius of the inner wall of the straight cylinder part 311 is greater than or equal to the radius of the outer wall of the guiding cylinder 50, the radius of the outer wall of the flanging part 312 is greater than the radius of the outer wall of the straight cylinder part 311, the radius of the inner wall of the first guiding structure 23 is greater than or equal to the radius of the outer wall of the straight cylinder part 311, and the radius of the inner wall of the positioning structure 12 is greater than or equal to the radius of the outer wall of the flanging part 312.

[0134] In Figure 17 the spring-opening structure 31 shown by the solid line is in the first position, and the spring-opening structure 31 shown by the dotted line is in the second position. When in the second position, the top surface of the flanging part 312 contacts the end surface of the first guiding structure 23 facing the outer door 10. In the first position, the top region of the spring-opening structure 31 is located between the first guiding structure 23 and the guiding cylinder 50, and in the second position, the bottom region of the spring-opening structure 31 is located between the first guiding structure 23 and the guiding cylinder 50. As can be seen from the above, during the movement of the spring-opening structure 31 between the first position and the second position, the spring-opening structure 31 always has a partial region located between the first guiding structure 23 and the guiding cylinder 50, and the guiding cylinder 50 and the first guiding structure 23 respectively play a radial limiting role on the straight cylinder part 311 from the inner and outer sides of the straight cylinder part 311, so that the spring-opening structure 31 has stronger stability during the axial movement process, and reduces the shaking of the spring-opening structure 31 during the movement between the first position and the second position.

[0135] In a technical solution, the length of the guiding cylinder 50 located in the inner cavity 313 is greater than the distance between the first position and the second position. Taking the surface of the flanging part 312 away from the inner door 20 as the reference surface, the distance between the surface of the flanging part 312 away from the inner door 20 between the first position and the second position is L1, and the length of the guiding cylinder 50 located in the inner cavity 313 is L2, as Figure 17 shown, L2≥L1. It should be noted that the distance between the first position and the second position is the shortest distance in the axial direction of the guiding cylinder 50, and the length of the guiding cylinder 50 located in the inner cavity 313 is the length in the axial direction of the guiding cylinder 50.

[0136] In a technical solution, there is a gap of 0.05 mm - 0.25 mm between the side wall of the straight cylinder part 311 and the outer side wall of the guiding cylinder 50. The side wall of the straight cylinder part 311 refers to the inner wall of the straight cylinder part 311, and the gap size between the side wall of the straight cylinder part 311 and the outer wall of the guiding cylinder 50 is N1, and this size is the distance between the side wall of the straight cylinder part 311 and the outer side wall of the guiding cylinder 50 in the radial direction of the guiding cylinder 50. Exemplarily, N1 can be 0.05 mm, 0.10 mm, 0.15 mm, 0.20 mm, 0.25 mm, etc. In this setting method, there is a relatively small gap between the straight cylinder part 311 and the guiding cylinder 50, and this relatively small gap enables the straight cylinder part 311 to move more smoothly along the axial direction, and this relatively small gap enables the guiding cylinder 50 to have a relatively good limiting effect on the straight cylinder part 311.

[0137] As Figure and 17 shown, in an alternative embodiment, the outer door 10 further includes a first reinforcing rib 14, which is located at the axial center of the positioning structure 12 on the surface of the outer door 10, and the top surface of the first reinforcing rib 14 is perpendicular to the central axis of the elastic structure 32; one end of the elastic structure 32 contacts the first reinforcing rib 14. The first reinforcing rib 14 plays a supporting role for the elastic structure 32, and the first reinforcing rib 14 provides a plane perpendicular to the axis of the elastic structure 32 to reduce the possibility of the bottom surface of the elastic structure 32 tilting. As Figure 18 shown, the first reinforcing rib 14 can be in a cross-shaped plate structure, the intersection point of the cross-shaped plate-shaped first reinforcing rib 14 is located at the axial center of the guiding cylinder 50, the end of the first reinforcing rib 14 is connected to the inner wall of the guiding cylinder 50, and the bottom of the first reinforcing rib 14 is connected to the outer door body 11. The first reinforcing rib 14, the guiding cylinder 50 and the outer door body 11 are an integral structure. The setting of the first reinforcing rib 14 improves the connection strength at the connection between the guiding cylinder 50 and the outer door body 11.

[0138] Please continue to refer to Figure 18 、 Figure 16 and Figure 17 , in a feasible embodiment, the outer door 10 further includes a second reinforcing rib 15, and the second reinforcing rib 15 avoids the pop-up structure 31 and is connected to the outer wall of the guiding cylinder 50. The second reinforcing rib 15 avoiding the pop-up structure 31 means that the second reinforcing rib 15 is not within the moving stroke range of the pop-up structure 31, that is, the setting of the second reinforcing rib 15 will not affect the movement of the pop-up structure 31 between the first position and the second position. In one implementation, in the first position, the bottom surface of the flanging part 312 contacts the second reinforcing rib 15. In this setting method, the second reinforcing rib 15 strengthens the connection strength of the guiding structure on the outer door 10.

[0139] As Figure 18As shown, in a feasible implementation, the second reinforcing rib 15 has an inclined surface on the side away from the guiding cylinder 50 in the radial direction of the guiding cylinder 50, and the distance between this inclined surface and the guiding cylinder 50 in the radial direction gradually increases in the direction away from the inner door 20. This setting facilitates the demolding operation during the manufacturing process of integrally forming the guiding cylinder 50 and the outer door body 11, that is, it facilitates the production and processing of the outer door 10.

[0140] As Figure 16 shown, in a technical solution, the positioning structure 12 includes a supporting portion 121 and a locking portion 122. The supporting portion 121 is an arc-shaped plate structure. The locking portion 122 is installed on the inner side of the top of the supporting portion 121. The locking portion 122 contacts the outer side wall of the first guiding structure 23. When the elastic opening structure 31 is in the second position, the top surface of the region of the flanging portion 312 away from the straight cylinder portion 311 contacts the locking portion 122, and the top surface of the region of the flanging portion 312 close to the straight cylinder portion 311 contacts the end surface of the first guiding structure 23. Both the locking portion 122 and the first guiding structure 23 play a limiting role on the flanging portion 312.

[0141] In a feasible setting, a hollow area 121a is provided in the middle of the supporting portion 121. The hollow area 121a is a hole structure that penetrates the supporting portion 121 along the thickness direction of the supporting portion 121. The hollow area 121a is provided below the connection area between the supporting portion 121 and the locking portion 122. The setting of the hollow area 121a enables, during the manufacturing process of the outer door 10, a slider to be set in the hollow area 121a and moved to the area below the region for forming the locking portion 122, so as to form the locking portion 122 during the integral forming process. As can be seen from the above, the setting of the hollow area 121a facilitates the production and manufacturing of the locking portion 122 and reduces the production difficulty of the outer door 10.

[0142] Third Embodiment

It should be noted that Figure 20 and Figure 19 do not show all the structures of the body 2, and only the door frame of the body 2 for installing the washing machine door assembly 1 is shown as an example.

[0144] In an example, on both sides of the washing machine door assembly 1 in the width direction, one side is hinged to the body 2, and the other side can be locked with the body 2 through a locking structure. When the washing machine door assembly 1 is locked with the body 2 through the locking structure, the washing machine door assembly 1 is in a locked state; when the locking structure between the washing machine door assembly 1 and the body 2 is unlocked, the washing machine door assembly 1 is in an unlocked state.

[0145] The washing machine provided by the embodiment of the present application may be equipped with a voice control module, and the voice control module can control the unlocking of the locking structure.

[0146] Figure 20 For Figure 21 the sectional view along the G-G direction in Figure 19 For Figure 22 the enlarged view at H in Figure 21 Figure 22 As shown, when the washing machine door assembly 1 is in the closed state, the top of the straight cylinder part 311 of the pop-up structure �1 contacts the body 2, and the body 2 makes the pop-up structure 31 located at the first position.

[0147] Since the washing machine provided by this embodiment includes the washing machine door assembly 1 provided by the above first embodiment or the second embodiment, it at least has all the advantages of the washing machine door assembly 1, which will not be elaborated here.
