[0011] In one embodiment of the present application, the spring head is provided with a mounting groove communicating with the clamping hole, and the elastic body partially extends into the mounting groove;

[0012] The elastic pad further includes an inserting portion, which is in a long strip shape and is connected to an end of the clamping portion away from the abutting portion. The inserting portion can be inserted into the clamping hole.

[0013] In one embodiment of the present application, it further includes a seat;

[0014] The ejector head and the seat body are slidably nested and matched, and two ends of the elastic body are respectively in contact with the ejector head and the seat body.

[0015] In one embodiment of the present application, the ejector head is provided with a limiting portion, and the seat body is provided with a guide portion, the guide portion is slidably engaged with the limiting portion, and the limiting portion and the guide portion cooperate to prevent the ejector head from detaching from the seat body.

[0016] On the second aspect, the present application also proposes a door assembly, including a front sealing door, a door body, a door lock assembly and a pop-up mechanism as described above, wherein the door body can be installed on the front sealing door in an openable and closable manner; the door lock assembly can be releasably connected between the front sealing door and the door body; the pop-up mechanism is installed on one of the front sealing door and the door body, and can elastically press against the other of the front sealing door and the door body.

[0017] In one embodiment of the present application, the door body includes an inner door body and an outer door body that are covered and connected to each other, a receiving cavity is defined between the inner door body and the outer door body, a through hole connected to the receiving cavity is provided on the inner door body, and a part of the structure of the pop-up mechanism is provided with the top support portion passing through the through hole, and the other part of the structure of the pop-up mechanism away from the top support portion is limited in the receiving cavity and is clamped between the inner door body and the outer door body.

[0033] The realization of the objectives, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of this application clearer, the following part will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0035] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application, as detailed in the appended claims.

[0036] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, in the description of this application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0038] In washing machines, dryers and other clothing processing equipment, the door assembly is used to open and close the loading port. In some fully automatic clothing processing equipment, an electronic door lock and a pop-up structure are provided to cooperate with each other to realize the automatic opening of the door assembly. During operation, the electronic door lock releases the door of the clothing processing equipment, and then the pop-up structure pops the door open, thereby realizing automatic door opening, which can improve the convenience of use.

[0039] The pop-up structure usually includes multiple components such as a pop-up head and a spring. In related technologies, the clothing processing equipment will be provided with ribs, holes and other structures for fixed connection of the plate structure in the door plate structure. The ribs are used to guide, limit and fix the pop-up head and the spring. In this way, during the assembly process, multiple components of the pop-up structure need to be assembled independently multiple times during the door assembly process. Such a setting will obviously reduce the assembly efficiency and is not conducive to reducing costs.

[0040] To resolve the above issues, please refer to Figures 1 to 3 The present application proposes a clothing processing device, which includes a device body (not shown) and a door assembly 1. The device body has a clothing processing chamber and a loading port connected to the clothing processing chamber. The clothing processing chamber can be used to wash clothes, or it can be used to care for, remove odors from, dry, and other functions of the clothing processing device. Of course, the clothing processing chamber can also integrate multiple functions such as washing, drying, and care. Specifically, the device body may include a shell and a barrel assembly arranged in the shell. The barrel assembly has a clothing processing chamber and a loading port. A water pump system may also be provided in the device body, and the water pump system is used to inject cleaning liquid into the clothing processing chamber to achieve the clothing washing function. The device body may also include a heat pump system or an auxiliary heating system arranged in the shell, and the heat pump system or the auxiliary heating system is used to achieve the functions of drying and caring for the clothes in the clothing processing chamber. It can be understood that when the clothing processing device integrates washing functions and drying, care, and other functions, the above functions can be controlled in time sequence, and different functions can be switched in different time sequences.

[0041] The door assembly 1 can be set on the front side of the shell. The door assembly 1 is used to open or close the loading port, and the user can put the clothes into the clothing processing chamber through the loading port. For example, during the implementation of functions such as washing and drying, the loading port is in a closed state. Before these functions are implemented, the loading port can be opened to put clothes into the clothing processing chamber and to take clothes out of the clothing processing chamber after the implementation is complete. Of course, in some usage scenarios, the loading port can be opened in the middle of the implementation of the above functions to perform the mid-way detergent addition and clothing increase and decrease functions, and this application does not limit this.

[0042] Specifically, the door assembly 1 includes a front sealing door 20, a door body 30, a door lock assembly 40, and a pop-up mechanism 10. The front sealing door 20 can be a sheet metal structure and defines an avoidance opening that docks with the delivery port. The door body 30 can be installed on the front sealing door 20 in an openable and closable manner and is arranged at the avoidance opening, thereby being able to open and close the delivery port. The door lock assembly 40 is releasably connected between the front sealing door 20 and the door body 30. Specifically, the door lock assembly 40 can include a lock body and a lock tongue 41. The lock body and the lock tongue 41 are releasably connected. The lock body can be installed on the front sealing door 20, and the lock tongue 41 is installed on the door body 30. During the above-mentioned washing or drying program, the door body 30 is closed to the delivery port, and the lock tongue 41 is locked in the lock body to stably maintain the door body 30 in a state of closing the delivery port.

[0043] It should be noted that the door body 30 of the present application can be opened and closed in the process of flipping open or in the form of translation opening, and this application does not impose any restrictions on this. In the case of flip opening, the door body 30 is connected to the front sealing door 20 via a hinge 50, so that the door body 30 can flip open the delivery port around the hinge 50. Generally, the door body 30 can flip open and close the delivery port in the horizontal direction around the hinge axis along the vertical direction. When the door body 30 adopts the translation form to open the delivery port, the door body 30 and the front sealing door 20 can also be connected by a hinge structure, but the specific form of the hinge structure will be different from the hinge 50 form of flip opening. However, there are relatively mature solutions for the hinge design in the current mechanical structure that can meet this form of movement, which will not be described here.

[0044] Furthermore, the door lock assembly 40 can be in the form of an electronic door lock, that is, the door lock assembly 40 can realize the function of automatically opening the door body 30. During the actual use of the clothing processing equipment, for example, when the user wants to put clothes in, he holds the clothes with both hands. After the door lock assembly 40 is released, it is difficult to free up his hands to open the door body 30 to a larger angle so as to put the clothes into the clothing processing chamber. At this time, the pop-up mechanism 10 included in the door assembly 1 of the present application can realize this function.

[0045] The pop-up mechanism 10 of the present application is installed on the front sealing door 20 or the door body 30. Taking the solution of flipping the door body 30 in the horizontal direction to open as an example, the pop-up mechanism 10 can be installed on the door body 30 and adjacent to the hinge 50. In this way, during the opening process of the door body 30, the pop-up mechanism 10 will elastically press against the front sealing door 20 and provide a reaction force acting on the door body 30, thereby driving the door body 30 to rotate around the hinge 50 and open.

[0046] For example, please refer to Figure 3 and Figure 4 There may be two pop-up mechanisms 10, and the two pop-up mechanisms 10 are respectively arranged on the upper and lower opposite sides of the hinge 50 in the upper and lower directions. Of course, the present application does not limit the specific number of pop-up mechanisms 10, and the number of pop-up mechanisms 10 may also be 1, 3, 4, etc.

[0047] In other arrangements, the pop-up mechanism 10 may also be installed on a side of the front closure door 20 or the door body 30 away from the hinge 50. In this arrangement, the number of the pop-up mechanism 10 may also be 1, 2, etc. This application does not impose any restrictions on this.

[0048] It can be understood that when the door body 30 of the present application is opened by translation, the pop-up mechanism 10 will drive the door body 30 to slide translationally, for example, to achieve translation in the left and right directions, or translation from top to bottom.

[0049] Please refer to Figure 5 and Figure 6 In the present application, the pop-up mechanism 10 can be installed on the door body 30 , and during the opening process of the door body 30 , it elastically presses against the front sealing door 20 .

[0050] In one embodiment, the pop-up mechanism 10 includes a pop-up head 11, an elastomer 13 and an elastic pad 14; the elastomer 13 is connected to the pop-up head 11, and the elastomer 13 can be compressed under the action of external force to store energy, and drive the pop-up head 11 by releasing energy; the elastic pad 14 has a top-butting portion 141 protruding from the pop-up head 11, and the top-butting portion 141 is used to push against the front sealing door 20. Since the pop-up mechanism 10 acts on the front sealing door 20 during the opening process of the door body 30, in order to ensure higher structural strength, the pop-up head 11 is usually made of plastic material, such as ABS (acrylonitrile-butadiene-styrene copolymer) or POM (polyoxymethylene) material. The material is harder and affects the pop-up angle, and when the door is opened and closed back and forth, the pop-up head 11 and the front sealing door 20 collide back and forth, which will wear the front sealing door 20. Moreover, the spring head 11 is mostly black. When the black spring head 11 hits the front sealing door 20, the color transfer problem is likely to occur, and a black mark will appear on the front sealing door 20, affecting the appearance of the front sealing door 20 and leaving a bad impression on the user.

[0051] Therefore, the material of the elastic pad 14 of the present application is different from that of the elastic head 11. The abutting portion 141 is provided at one end of the elastic head 11 away from the elastic body 13, so that the abutting portion 141 can abut against the front sealing door 20 (refer to FIG. Figure 6 ).

[0052] The elastic pad 14 of the present application is primarily used to provide the elastic force required to push open the door body 30, and overcomes the drawback of the material used for the aforementioned spring-loaded head 11, which easily stains the front door 20. Specifically, the material hardness of the elastic pad 14 is less than that of the spring-loaded head 11. The hardness of the elastic pad 14 can range from 55 to 65 degrees. For example, the elastic pad 14 can have values ​​of 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, or 65 degrees. This prevents the elastic pad 14 from being too weak, resulting in structural damage over time, and also prevents the elastic pad 14 from being too strong, resulting in poor rebound performance. In one specific material choice, the elastic pad 14 can be made of silicone, such as white silicone. This utilizes the high resilience of silicone to better facilitate the opening of the door body 30 and effectively prevents staining of the front door 20. It is understandable that the elastic pad 14 can also be made of other materials with similar properties to silicone, and this application does not limit this.

[0053] Furthermore, the elastic pad 14 is detachably fixedly connected to the spring head 11. Such an arrangement makes it easy to replace the elastic pad 14 when the spring head 11 is used for a long time.

[0054] In one embodiment, the elastic pad 14 is detachably connected to the ejector head 11, and the elastic pad 14 and the ejector head 11 are snap-fitted. Specifically, the ejector head 11 is provided with a snap-fitting hole 114, and the elastic pad 14 also includes a snap-fitting portion 142 connected to the abutting portion 141. The snap-fitting portion 142 snaps into the snap-fitting hole 114 and is blocked by the wall of the ejector head 11 in the direction of removal. Specifically, the snap-fitting hole 142 is in the shape of a stepped hole, and the snap-fitting portion 142 includes a connecting section 143 and a snap-fitting joint 144. The outer diameter of the snap-fitting joint 144 is larger than that of the connecting section 143. The connecting section 143 and the snap-fitting joint 144 are respectively located at positions with different apertures in the snap-fitting hole 114, thereby achieving snap-fitting installation. When the elastic pad 14 is installed by snap-fitting, assembly is more convenient.

[0055] Furthermore, a limiting groove 115 is formed in a recessed manner at one end of the spring-loaded head 11 away from the base 12, and a portion of the structure of the abutting portion 141 is accommodated in the limiting groove 115. It can be understood that the provision of the limiting groove 115 can effectively support the side wall of the abutting portion 141 during its deformation process, thereby preventing the abutting portion 141 from tilting excessively during the process of pushing the door body 30 open.

[0056] In order to improve the convenience of assembling the elastic pad 14 to the spring-loaded head 11, the elastic pad 14 can further include an inserting portion 145, which is in the shape of an elongated strip and is connected to the end of the clamping portion 142 away from the top portion 141. The spring-loaded head 11 is also provided with a mounting groove 117 connected to the clamping hole 142. The elastic body 13 partially extends into the mounting groove 117, and the inserting portion 145 can be inserted into the clamping hole 114. In this embodiment, the outer diameter of the plug-in portion 145 is smaller than the aperture of the snap-in hole 114, and the length of the plug-in portion 145 is longer. After assembly, the plug-in portion 145 can partially exceed the end of the spring-loaded head 11 away from the top portion 141. The advantage of this arrangement is that after the elastic pad 14 is aligned with the snap-in hole 114 through the plug-in portion 145, force can be applied to the portion of the plug-in portion 145 exposed from the spring-loaded head 11 to apply tension to the elastic member, thereby quickly enabling the above-mentioned snap-in portion 142 to snap into place.

[0057] It should be noted here that the detachable connection method between the elastic pad 14 and the spring head 11 can be other forms besides the snap connection method, such as connection through connecting parts, such as threaded connection, pin connection, etc., and this application does not impose any restrictions on this.

[0058] The elastic pad 14 and the spring-loaded head 11 described above have the advantage of being easy to replace when they are set separately. In other settings, the elastic pad 14 and the spring-loaded head 11 can also be an integrated structure, for example, they can be manufactured into one piece by secondary injection molding, or fixed into one piece by bonding, hot melting or other fixing methods.

[0059] Furthermore, compared to the traditional solution in which multiple parts of the pop-up mechanism are installed on the door body 30 in a scattered manner, the solution of the present application also realizes a modular design of the pop-up mechanism 10 to facilitate modular assembly of the entire pop-up mechanism 10.

[0060] Please refer to Figure 5 and Figure 6In one embodiment, the ejection mechanism 10 also includes a seat body 12, wherein the ejection head 11 is provided with a limiting portion 112; the seat body 12 is provided with a guide portion 124, and the guide portion 124 is slidably limited in cooperation with the limiting portion 112 to prevent the ejection head 11 from being separated from the seat body 12; an elastic body 13 is connected to the ejection head 11 and the seat body 12, and the elastic body 13 can be compressed under the action of external force to store energy, and release energy to drive the ejection head 11 to perform telescopic movement relative to the seat body 12.

[0061] The seat 12 can be detachably mounted on the door body 30 .

[0062] The base 12 of the present application is fixed to the door body 30, and the base 12 and the door body 30 are separate structures, and the base 12 and the pop-up head 11 are matched with the sliding limit of the limit part 112 and the guide part 124, and are combined with the elastic body 13 to form a module. In this way, the entire pop-up mechanism 10 can be fixed to the door body 30 by the base 12 to achieve overall modular installation. Such a structural form, on the one hand, can assemble the pop-up mechanism 10 outside the door body 30. Obviously, since there is no interference from the door body 30 during the assembly process of the pop-up mechanism 10, the assembly operation is more convenient and more efficient. After assembling the pop-up mechanism 10, the entire pop-up mechanism 10 can be assembled to the door body 30 with the base 12 as the connection reference. This can facilitate the assembly of the pop-up mechanism 10 to the door body 30 on the automatic assembly line, thereby improving production efficiency and reducing costs.

[0063] Please refer to Figures 4 to 6 In one embodiment, the door body 30 includes an inner door body 31 and an outer door body 32 that cover and connect with each other. A receiving cavity 301 is defined between the inner door body 31 and the outer door body 32. The inner door body 31 is provided with a through hole 313 that communicates with the receiving cavity 301. A portion of the eject head 11 passes through the through hole 313. The seat body 12 is limited in the receiving cavity 301 and is clamped between the inner door body 31 and the outer door body 32. In this application, since the entire ejection mechanism 10 is assembled into an integral structure with the seat body 12 as a reference, the inner door body 31 and the outer door body 32 clamp the limited seat body 12, so that the installation of the entire ejection mechanism 10 can be achieved. This assembly form facilitates positioning and greatly improves assembly efficiency.

[0064] The door body 30 of the present application may further include an anti-scalding cover 33 and a glass bowl 34, wherein the inner door body 31 and the outer door body 32 may both constitute an annular structure, that is, a viewing window may be formed between the two, and the anti-scalding cover 33 is connected to the outer side of the outer door body 32 and covers the outer opening of the viewing window, wherein the anti-scalding cover 33 may be a transparent setting, or at least the part corresponding to the viewing window is a transparent setting, and the glass bowl 34 is connected to the inner side of the inner door body 31 and covers the outer opening of the viewing window, so that the user can conveniently observe the situation in the clothing processing chamber through the viewing window during use of the clothing processing device.

[0065] Please refer to Figures 7 to 9 In one embodiment, the ejection head 11 and the base 12 of the ejection mechanism 10 are slidably nested. This structure provides effective support from the base 12 during the ejection head 11's telescopic movement relative to the base 12, significantly enhancing the stability of the ejection head 11 during the application of force to open the door body 30. It should be noted that while the ejection head 11 and the base 12 can slide relative to each other, they do not necessarily need to be strictly nested. Other sliding connections may also be possible, such as through a dovetail groove or a shape-fitting track, and this application is not limited thereto.

[0066] In a nested matching structure, the base body 12 and the ejector head 11 can both be approximately cylindrical structures, wherein the base body 12 has a mounting cavity 122 and an opening 123 connected to the mounting cavity 122, and the ejector head 11 can be movably mounted in the mounting cavity 122 and can extend outward relative to the base body 12 from the opening 123.

[0067] The guide portion 124 is a guide groove that communicates with the mounting cavity 122 and has stop walls at both ends in the movement direction of the ejector head 11 . The limiting portion 112 is a limiting protrusion that is inserted into the guide groove and slides between the two stop walls.

[0068] exist Figures 7 to 9 In the exemplary structure shown, the ejector head 11 is embedded in the base body 12. In this way, during the sliding and retracting process of the ejector head 11, the ejector head 11 will be supported by the cavity wall of the mounting cavity 122, so that it is not easy to tilt or loosen during the process of pushing open the door body 30, and the structure is more stable and reliable.

[0069] Specifically, the ejector head 11 includes a first cylinder 111 with a cover at one end, the above-mentioned mounting groove 117 is formed inside the first cylinder 111, and a snap-in hole 114 connected to the mounting groove 117 is provided. The limiting protrusion is connected to the outer wall of the first cylinder 111 and extends outward, and the base body 12 includes a second cylinder 121 with a cover at one end, and the guide groove passes through the cylinder wall of the second cylinder 121, but the guide groove is not through in the length direction of the second cylinder 121. In this way, the guide groove has two stop walls at both ends in the telescopic movement direction of the ejector head 11.

[0070] To enhance the stability of the connection between the projectile head 11 and the base 12, at least two guide grooves are evenly spaced along the circumference of the base 12, and the limiting protrusions are provided in a one-to-one correspondence with the guide grooves. The figure shows an example of two limiting protrusions and two guide grooves, but the number of limiting protrusions and guide grooves can also be three, four, etc., and this application does not impose any limitation on this.

[0071] In addition, in other embodiments, the positions of the limiting protrusion and the guide groove may also be interchanged between the ejector head 11 and the seat body 12 .

[0072] Furthermore, taking the example of a limiting protrusion set on the ejector head 11, during the process of assembling the ejector head 11 to the base body 12, the ejector head 11 can be forced to deform and enter the installation cavity 122 through extrusion, and the limiting protrusion is reset and expanded outward in the installation cavity 122 and finally stuck in the guide groove. In this way, under the connection and cooperation between the limiting protrusion and the guide groove, the two will be difficult to separate, and thus the entire ejection mechanism 10 is a modular whole.

[0073] In order to facilitate the assembly of the ejector head 11 into the seat body 12, the present application may further provide a deformation groove 113 on the first cylindrical body 111. The deformation groove 113 is provided on each of the limiting protrusions along the circumference of the first cylindrical body 111. Such a configuration can make it easier for the limiting protrusions to deform, making assembly more convenient. It is understood that the limiting protrusions and the first cylindrical body 111 of the present application can be formed into an integral structure, that is, the two can be integrally formed, and the deformation groove 113 can be integrally formed during the production process of the ejector head 11. Of course, it can also be formed by removing part of the material in a later stage of processing, and the present application does not limit this. Furthermore, on this basis, this embodiment can further form a guide slope 125 on the seat body 12, and form an extrusion slope 116 in the structure of the limiting protrusion. In this way, during the process of inserting the spring head 11 into the seat body 12, it is easier to align and deform the limiting protrusion, so that it can smoothly enter the installation cavity 122 of the seat body 12.

[0074] The elastic member of this application is a spring, supported between the ejector head 11 and the base 12, and located within the mounting cavity 122. The spring can be placed in the mounting cavity 122 before the ejector head 11 is assembled to the base 12. This arrangement effectively limits the spring's position and achieves a concealed effect, making the modular structure of the entire ejection mechanism 10 more compact and stable. Of course, the elastic member can also take the form of an elastic block, a spring clip, or other similar form, and this application does not limit this.

[0075] It can be understood that the projectile head 11 of the present application can also be sheathed on the outside of the seat body 12, that is, an inner cavity is formed inside the projectile head 11, and the seat body 12 partially extends into the inner cavity of the projectile head 11, and the part of the seat body 12 exposed outside the projectile head 11 can be clamped and limited by the inner door body 31 and the outer door body 32.

[0076] In addition, it should be emphasized that the above content exemplifies that the guide portion 124 and the limiting portion 112 are in the form of a guide groove and a limiting protrusion, while in other structural forms, the two can also be in the form of a guide rod and a sleeve that slide together, and this application does not impose any restrictions on this.

[0077] Please refer to Figure 6 and Figure 10 To ensure stable positioning of the ejection mechanism 10 within the receiving cavity 301 after assembly, the inner door body 31 includes a base plate 311 and a retaining wall 312. The retaining wall 312 is disposed within the receiving cavity 301 and is connected to the base plate 311 and disposed around the periphery of the through hole 313. Part of the base body 12 is inserted into the retaining wall 312. The retaining wall 312 is cylindrical in shape, allowing the base body 12 to be inserted into the portion facing the base plate 311. This ensures that, after assembly, the base body 12 will not substantially shift within the receiving cavity 301, providing a more stable installation structure.

[0078] In another embodiment, a flexible pad 60 is further provided in the receiving cavity 301 and supported between the base 12 and the outer door body 30. The flexible pad 60 can also be made of silicone. The provision of the flexible pad 60 provides a pre-tightening force for the base 12 to move toward the inner door body 31, thereby stably maintaining the base 12 in a state of pressing against the outer door body 32 and preventing it from moving from the outer door body 32 toward the inner door body 31. This makes the installation structure more stable.
