Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, specifically relating to a door assembly and clothing processing equipment. Background Technology

[0002] The door assembly of existing garment processing equipment generally consists of an inner door ring and an outer door ring, which are assembled into the door assembly by bolts or snap-fit ​​connections. To reduce the overall thickness of the door assembly, the handle is typically recessed from part of the inner door ring towards the outer door ring, thus facilitating operation without increasing the overall thickness of the door assembly.

[0003] However, because the handle is partially recessed within the door ring, its thickness is reduced compared to the surrounding structure, making it difficult to install bolt or snap-fit ​​structures. This results in the inner and outer rings of the door not being tightly connected at the handle position, which can easily lead to gaps. Consequently, the inner and outer rings of the door vibrate relative to each other and generate noise. Summary of the Invention

[0004] The purpose of this invention is to at least solve the problem of gaps easily appearing between the inner and outer rings of a door at the handle position. This purpose is achieved through the following means:

[0042] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0043] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0044] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0045] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0046] To address the issue of gaps easily appearing between the inner and outer rings of a door at the handle position, this application proposes a door assembly and a garment processing device incorporating the door assembly. By using the door assembly of this application, the connection strength between the outer and inner rings at the handle position can be effectively enhanced, thereby preventing gaps from appearing at the handle position and thus avoiding relative vibration and noise between the outer and inner rings.

[0047] The clothing processing equipment in this application can be a washing machine, a dryer, or a washer-dryer combo. It can be a drum-type clothing processing equipment or a top-loading clothing processing equipment. For ease of description, the embodiments in this application are only illustrated by taking a drum washing machine as an example.

[0048] like Figure 1As shown, in some embodiments of the present invention, the garment processing device 100 includes a housing 2, which forms the external structure of the garment processing device 100. The housing 2 has an internal mounting cavity for mounting a roller and various other components. The roller is disposed in the mounting cavity and is arranged horizontally or at an angle to the horizontal direction. When the roller is at an angle to the horizontal direction, the angle is very small, and the roller as a whole is still generally horizontal. The roller has a garment processing cavity inside for storing garments, thereby washing and dehydrating them. The front end of the roller has a garment inlet 201 communicating with the garment processing cavity. The front end of the housing 2 has an opening opposite to the garment inlet 201. A door assembly 1 is connected to the opening and is rotatably connected to the opening of the housing 2. By rotating the door assembly 1, the opening can be opened, allowing garments to be sequentially placed into the garment processing cavity through the opening and the garment inlet 201 for washing and dehydration.

[0049] Combination Figures 1 to 8 As shown, in some embodiments of the present invention, the door assembly 1 includes an outer door ring 10 and an inner door ring 20, the inner door ring 20 being connected to the outer door ring 10, and at least a portion of the inner door ring 20 being recessed toward the outer door ring 10 to form a handle portion 21; wherein, one of the outer door ring 10 and the inner door ring 20 is provided with at least one insertion hole 111 at a position corresponding to the handle portion 21, and the other of the outer door ring 10 and the inner door ring 20 is provided with at least one insertion post 22 at a position corresponding to the handle portion 21, the insertion post 22 being inserted into the insertion hole 111 and fixedly connected.

[0050] Specifically, the outer door ring 10 and part of the inner door ring 20 are located at the front end of the exterior of the housing 2. The part of the inner door ring 20 is recessed towards the outer door ring 10 to form a handle portion 21, thereby increasing the distance between the inner door ring 20 and the front end face of the housing 2, making it easier to insert a hand into the handle portion 21 and operate the door assembly 1, thereby rotating the door assembly 1.

[0051] However, since the thickness of the door assembly 1 is thinner along the front-rear direction of the housing 2 at the position where the handle part 21 is located, it is not convenient to connect it to the outer ring 10 of the door by bolts or clips. As a result, the connection of the door assembly 1 at the position of the handle part 21 is unreliable and gaps are easy to appear. Therefore, by inserting the plug 22 into the plug hole 111 and fixing it, the connection strength between the outer ring 10 and the inner ring 20 at the position of the handle part 21 can be effectively enhanced, thereby avoiding gaps at the position of the handle part 21 and thus avoiding relative vibration and noise between the outer ring 10 and the inner ring 20.

[0052] In some embodiments of the present invention, the number of handle portions 21 may be one or more. In some embodiments of the present invention, the number of handle portions 21 is two, and the two handle portions 21 are spaced apart along the circumferential direction of the inner door ring 20. At the same time, at the position of any handle portion 21, the outer door ring 10 and the inner door ring 20 are fixedly connected to the insertion holes 111 by insertion posts 22. Wherein, at the position of the same handle portion 21, the number of insertion posts 22 and insertion holes 111 may be multiple, and the multiple insertion holes 111 are spaced apart along the circumferential direction of the door assembly 1 and are corresponding one-to-one with the multiple insertion posts 22.

[0053] like Figure 8 As shown, in some embodiments of the present invention, the outer wall surface of the plug post 22 and the inner wall surface of the plug hole 111 can be bonded together, that is, an adhesive is provided between the two, or the plug post 22 and the plug hole 111 can be interference fit, thereby enhancing the connection strength between the outer ring 10 and the inner ring 20 at the handle portion 21.

[0054] Combination Figures 6 to 8 As shown, in some embodiments of the present invention, the outer ring 10 of the door is provided with a plug hole 111, the inner ring 20 of the door is provided with a plug post 22, and an adhesive is provided between the plug post 22 and the plug hole 111.

[0055] By providing a plug hole 111 in the outer ring 10 of the door and a plug post 22 in the inner ring 20 of the door, it is convenient to apply adhesive into the plug hole 111 in the direction of the outer ring 10 of the door, and to allow the adhesive to flow between the outer wall surface of the plug post 22 and the inner wall surface of the plug hole 111, thereby achieving an adhesive fit between the two.

[0056] Specifically, during the assembly of door assembly 1, along... Figure 4 The outer ring 10 is vertically positioned above the inner ring 20, and adhesive is applied to the side of the outer ring 10 facing away from the inner ring 20 and into the insertion hole 111. The adhesive flows under its own gravity between the outer wall of the insertion post 22 and the inner wall of the insertion hole 111. The adhesive can be silicone sealant.

[0057] In some embodiments of the present invention, there may be two insertion holes 111. The two insertion holes 111 are spaced apart along the circumferential direction of the outer ring 10 at positions corresponding to the handle portion 21 on the outer ring 10. The number of insertion pins 22 is the same as the number of insertion holes 111, which is also two. The two insertion pins 22 are spaced apart along the circumferential direction of the inner ring 20 on the surface of the handle portion 21 facing the outer ring 10.

[0058] Combination Figures 6 to 8As shown, in some embodiments of the present invention, along the direction from the outer ring 10 to the inner ring 20, the insertion hole 111 includes at least two insertion hole portions with successively increasing diameters, and the insertion post 22 includes at least two insertion post segments with successively increasing diameters. The number of at least two insertion hole portions and at least two insertion post segments are the same and are arranged in a one-to-one correspondence, and the diameter of the insertion hole portion is larger than the diameter of the corresponding insertion post segment.

[0059] By setting the insertion hole 111 as a stepped hole structure and the insertion post 22 as a stepped post structure, the insertion post 22 and the insertion hole 111 are positioned for easy insertion.

[0060] Meanwhile, since the diameter of the insertion hole is larger than the diameter of the corresponding insertion post, when adhesive is applied to the insertion hole 111 in the direction of the outer ring 10, the adhesive can flow along the axial direction of the insertion post 22, thereby ensuring that most of the surface of the insertion post 22 is covered with adhesive in the axial direction, thus ensuring the bonding strength between the insertion post 22 and the insertion hole 111.

[0061] Meanwhile, the stepped structure can provide a certain load-bearing capacity. When the adhesive flows between two adjacent plug segments, some of the adhesive will remain on the stepped surface between the two plug segments and the stepped surface between the two plug holes, thereby further improving the bonding strength between the plug 22 and the plug hole 111.

[0062] Combination Figures 6 to 8 As shown, in some embodiments of the present invention, at least two insertion holes include a first insertion hole (not shown in the figure) and a second insertion hole (not shown in the figure) with successively increasing diameters, and at least two insertion post segments include a first insertion post segment 221 and a second insertion post segment 222 with successively increasing diameters, wherein the first insertion post segment 221 is inserted into the first insertion hole, and the second insertion post segment 222 is inserted into the second insertion hole.

[0063] Specifically, the diameter of the first insertion post segment 221 is smaller than the diameter of the first insertion hole portion, and the first insertion post segment 221 is inserted into the first insertion hole portion. The diameter of the second insertion post segment 222 is smaller than the diameter of the second insertion hole portion, and the second insertion post segment 222 is inserted into the second insertion hole portion. This ensures that the diameter of the insertion hole portion is always larger than the diameter of the corresponding insertion post segment along the axial direction of the insertion post 22, thereby ensuring that the adhesive can flow in the insertion hole 111 along the axial direction of the insertion post 22.

[0064] Combination Figures 6 to 8 As shown in some embodiments of the present invention, the end of the insertion hole 111 away from the inner ring 20 of the door is provided with a guide surface 1111.

[0065] Specifically, the guide surface 1111 can be an annular surface formed by a straight segment along the circumference, or the guide surface 1111 can be an annular surface formed by an arc segment along the circumference. Since the adhesive needs to be applied through the direction of the outer ring 10, the guide surface 1111 is provided to facilitate the concentration of the adhesive at the position of the insertion hole 111 and its flow into the interior of the insertion hole 111.

[0066] Combination Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, the door assembly 1 further includes a heat shield 30, which is attached to the surface of the outer ring 10 away from the inner ring 20, and the projection of the insertion hole 111 in the direction perpendicular to the heat shield 30 is within the range of the heat shield 30.

[0067] Specifically, the heat shield 30 can be connected to the outer ring 10 of the door by adhesive or snap-fit. When adhesive needs to be applied into the insertion hole 111, the adhesive can be applied around the insertion hole 111 or inside the insertion hole 111. Then, the heat shield 30 is connected to the surface of the outer ring 10 away from the inner ring 20 of the door. Since the heat shield 30 is attached to the surface of the outer ring 10 of the door, and the projection of the insertion hole 111 in the direction perpendicular to the heat shield 30 is within the range of the heat shield 30, the adhesive can flow into the interior of the insertion hole 111 under the pressure of the heat shield 30, thereby achieving the bonding between the insertion hole 111 and the insertion post 22. In some embodiments of this application, the heat shield 30 can be connected to the outer ring 10 of the door by adhesive bonding. Therefore, there is no need to apply adhesive to the insertion hole 111. When the heat shield 30 is bonded to the outer ring 10 of the door, the adhesive between the heat shield 30 and the outer ring 10 of the door can flow to the insertion hole 111 under the pressure and eventually flow into the insertion hole 111.

[0068] In some embodiments of the present invention, the outer ring 10 of the door is provided with a mounting surface 11 on the surface opposite to the inner ring 20 of the door. The radially outer side of the mounting surface 11 protrudes from the mounting surface 11, thereby forming a mounting groove on the surface of the outer ring 10 opposite to the inner ring 20 of the door. The anti-scalding cover 30 is disposed in the mounting groove, and the surface of the anti-scalding cover 30 away from the inner ring 20 is flush with the radially outer protruding structure of the mounting surface 11, thereby ensuring that the outer surface of the door assembly 1 is a flat plane, preventing dust accumulation and improving the appearance of the door assembly 1. When the anti-scalding cover 30 is bonded to the outer ring 10, an adhesive is applied to the mounting surface 11, thereby bonding the anti-scalding cover 30 to the outer ring 10 with the adhesive. At the same time, the adhesive can flow to the insertion hole 111 under the squeezing action of the anti-scalding cover 30 and the outer ring 10, and finally flow into the insertion hole 111.

[0069] Combination Figure 5 , Figure 6 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, an overflow groove 112 is recessed on the mounting surface 11. The overflow groove 112 can be an annular groove, so that when there is too much adhesive between the anti-scalding cover 30 and the mounting surface 11, the excess adhesive can be squeezed into the overflow groove 112, preventing the excess adhesive from flowing out to the outside of the door assembly 1 through the gap between the anti-scalding cover 30 and the outer ring 10 of the door, thereby affecting the appearance of the door assembly 1. In some embodiments of the present invention, the overflow groove 112 can also be configured as multiple non-interconnected groove structures, and the multiple groove structures are spaced apart along the circumferential direction of the mounting surface 11.

[0070] Combination Figure 9 and Figure 10 As shown, in some embodiments of the present invention, the door assembly 1 includes a connecting screw (not shown in the figure), and the outer ring 10 of the door is provided with a countersunk hole 113 on the surface opposite to the inner ring 20 of the door. The threaded section of the connecting screw passes through the countersunk hole 113 and is threadedly connected to the inner ring 20 of the door.

[0071] Specifically, the outer ring 10 and the inner ring 20 are connected by connecting screws to ensure the connection strength between them. Since the outer ring 10 has a heat shield 30 on its surface facing away from the inner ring 20, a countersunk hole 113 is provided to prevent the connecting screws from interfering with the installation of the heat shield 30. The end of the connecting screw is placed inside the countersunk hole 113, ensuring a close fit between the heat shield 30 and the mounting surface 11. For ease of connection, the inner ring 20 has a mounting post 23 on its surface facing the outer ring 10. The mounting post 23 has a threaded hole along the axial direction, allowing the threaded section of the connecting screw to be inserted into and threadedly connected to the threaded hole.

[0072] Combination Figures 6 to 10 As shown, in some embodiments of the present invention, the insertion hole 111 is located outside the countersunk hole 113 along the radial direction of the outer ring 10 of the door.

[0073] Specifically, since the handle 21 is located near the outer edge of the inner ring 20, and the outer edge of the door assembly 1 at the corresponding position of the handle 21 is thin, it is difficult to set up a connection structure connecting the inner ring 20 and the outer ring 10. Therefore, the insertion hole 111 is set outside the countersunk hole 113 along the radial direction of the outer ring 10, and is connected to the insertion post 22 through the insertion hole 111, thereby improving the connection strength between the outer ring 10 and the inner ring 20 at the outer edge of the handle 21. The countersunk hole 113 is set inside the insertion hole 111 along the radial direction of the outer ring 10, away from the handle 21. The door assembly 1 has sufficient size along the front-back direction of the housing 2 to set up a connection structure for connecting the outer ring 10 and the inner ring 20, thus ensuring the connection strength between the outer ring 10 and the inner ring 20.

[0074] Combination Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, in some embodiments of the present invention, the door assembly 1 further includes a door glass 40, the circumferential edge of which is sandwiched between the outer door ring 10 and the inner door ring 20, and the center of the door glass 40 protrudes towards the clothing processing chamber. The outer door ring 10 has a first opening 12, and the inner door ring 20 has a second opening 24. The first opening 12 and the second opening 24 are opposite to each other and their shapes match the shapes of the door glass. The anti-scalding cover 30 is also transparent, allowing the contents of the clothing processing chamber to be observed through the door assembly 1 from the outside of the housing 2.

[0075] Combination Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments of the present invention, the door assembly 1 further includes a hinge assembly 50 and a door hook 60, which are respectively disposed on both sides of the door assembly 1 along the radial direction of the door assembly 1. The hinge assembly 50 connects the door assembly 1 and the housing 2, allowing the door assembly 1 to rotate and thus open or close the clothing storage opening 201. The door hook 60 connects to the housing 2, fixing the door assembly 1 to the opening of the housing 2 and preventing the door assembly 1 from rotating arbitrarily. In some embodiments of the present invention, when there are two handles 21, the two handles 21 can be respectively disposed on both sides of the door hook 60 along the circumferential direction of the door assembly 1, thereby facilitating rotation of the door assembly 1 from multiple positions.

[0076] Combination Figures 1 to 10 As shown, in some embodiments of the present invention, when the door assembly 1 is assembled, the door glass 40 is aligned along... Figure 4The second opening 24 of the inner door ring 20 is installed from top to bottom in the direction shown. The protruding portion of the door glass 40 passes through the second opening 24, and the outer edge of the door glass 40 abuts against the circumferential edge of the second opening 24. Then, the hinge assembly 50 and the door hook 60 are installed along... Figure 4 As shown, assemble the inner door ring 20 from top to bottom onto the corresponding mounting position. Then, assemble the outer door ring 10 along... Figure 4 The inner door ring 20 is assembled from top to bottom in the direction shown, and the inner door ring 20 and outer door ring 10 are connected and fixed by connecting screws. At this time, the first opening 12 and the second opening 24 are positioned opposite each other, and the circumferential edges of the first opening 12 and the second opening 24 together clamp and fix the outer edge of the door glass 40. Then, adhesive is applied to the mounting surface 11. The adhesive can be circumferentially covered on the mounting surface 11 and correspond to the position of the countersunk hole 113, thereby ensuring that the adhesive is in the middle position in the radial direction of the mounting surface 11. Finally, the anti-scalding cover 30 is installed along... Figure 4 The heat shield 30 is installed on the outer ring 10 of the door from top to bottom, and the heat shield 30 is pressed firmly. During the pressing of the heat shield 30, the adhesive spreads radially along the mounting surface 11 with sufficient space to ensure a reliable connection between the heat shield 30 and the outer ring 10. At the same time, during the pressing of the heat shield 30, the adhesive flows towards the insertion hole 111 under the pressure and eventually flows into the insertion hole 111, achieving an adhesive fit between the insertion hole 111 and the insertion post 22.

[0077] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
