This gives the washing machine a wider field of view for observing the washing process, increasing the convenience of observation for the user.

Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, and specifically relates to a washing machine. Background Technology

[0002] As people's living standards improve, washing machines are becoming increasingly common. For example... Figure 1 As shown, the front surface of the washing machine's casing includes a control panel 02 and a front panel 01 arranged adjacent to each other. A display module 03 for display is mounted on the control panel 02. An observation window 04 is hinged to the front panel 01, and a clothes inlet is provided on the front panel 04. The observation window 04 and the clothes inlet are sealed together and can be opened and closed. In other words, the front surface of the washing machine casing consists of two parts, making the structural strength of the front surface relatively weak, and there is a large gap between the control panel 02 and the front panel 01. Currently, the size of the observation window 04 is slightly larger than the clothes inlet, causing users to need to bend down to a position flush with the inlet when observing the washing process, which is inconvenient.

[0003] In addition, the display module is assembled onto the control panel from back to front, and then the control panel is installed onto the two side panels of the enclosure, which is quite complicated. Also, the display module may malfunction during use, and when it needs to be repaired, the control panel must be disassembled first, and then the display module must be disassembled, making the repair and disassembly operation quite troublesome.

[0004] Furthermore, viewed from the front of the machine, the gap between the display module and the control panel is quite large, known as the "black gap," allowing dripping water to easily enter and potentially reach electrical components, increasing the risk. Summary of the Invention

[0005] This invention addresses the problems of low structural strength of the front panel and difficulty in observing the washing process in existing technologies by providing a washing machine with an observation window set adjacent to the display module on the integrated front panel, thereby expanding the observable range.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] A washing machine includes an integrated front panel, a display module fixed to the front panel, and an observation window hinged to the front panel. The display module is disposed adjacent to the observation window, and a first edge end face and a second edge end face are respectively disposed adjacent to each other on the observation window and the display module.

[0008] Furthermore, the front panel includes an observation section for mounting the observation window and a control section for mounting the display module, wherein the observation section and the control section are an integral plate structure.

[0009] Furthermore, the second edge end face is the lower end face of the front of the display module; the first edge end face is the end face on the outer edge surface of the observation window and adjacent to the second edge end face.

[0010] Furthermore, both the first edge end face and the second edge end face are arc-shaped surfaces, and the distance between the first edge end face and the axis of the observation window is equal to the radius of the observation window.

[0011] Furthermore, both the first edge end face and the second edge end face are horizontal planes, and the distance between the first edge end face and the axis of the observation window is less than the radius of the observation window.

[0012] Furthermore, the front panel is provided with a mounting groove that matches the observation window. The mounting groove has a circular basin-shaped structure, and a circular clothing inlet is provided at the bottom of the mounting groove. The axis of the mounting groove is located above the axis of the clothing inlet.

[0013] Furthermore, a first opening matching the display module is provided on the front panel, and the mounting groove is configured to communicate with the first opening.

[0014] Furthermore, a rearward bend is formed by extending rearward and upward along the upper end wall of the mounting groove, and a rear extension is formed by continuing to extend rearward along the rearward bend, the rear extension being used to define the display module.

[0015] Furthermore, the rear extension is provided with an upwardly extending opening flange, the opening flange is provided with a first card hole, and the display module is provided with a rearwardly extending first card claw that matches the first card hole.

[0016] Furthermore, the first claw has a first insert plate extending rearward through the first card hole, a first claw portion disposed on the first insert plate, and a stop block protruding from the first insert plate for blocking the first opening flange, the stop block being located on the front side of the first claw portion.

[0017] Furthermore, the display module is obscured on the front side of the rear bend and the rear extension.

[0018] Furthermore, a decorative element is provided at the lower end of the display module to cover the front side of the rear bend and the rear extension.

[0019] The washing machine provided by this invention, by setting an integrated front panel, eliminates the control panel, reduces the number of components in the washing machine, reduces the manufacturing of the front control panel, and reduces the installation of the control panel on the front panel, which is beneficial to improving manufacturing and assembly efficiency. Furthermore, it eliminates the gap between the control panel and the front panel, preventing water seepage through the gap, and reducing the gap enhances the aesthetics of the washing machine. The integrated front panel also increases the structural strength of the cabinet. By positioning the display module adjacent to the observation window, with the observation window positioned upwards at the display module and having a second edge face immediately adjacent to the display module, the user can easily see the washing process of the clothes in the drum by simply adjusting their downward gaze after viewing the display screen. Increasing the area of ​​the observation window or moving it upwards increases the user's field of vision for observing the washing process, especially increasing the visible area diagonally above the washing machine, thus improving the convenience of observation.

[0020] Other features and advantages of the present invention will become clearer after reading the detailed embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0054] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0055] In the description of this invention, it should be noted that, under normal use, the side closer to the user is referred to as "front," and the side farther from the user is referred to as "rear." The terms "up," "down," "left," and "right," etc., indicate the orientation or positional relationship based on the positional relationship when the washing machine is in normal use. When describing a component, the direction closer to the component's axis or center is referred to as "inner," and vice versa. These terms are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; features defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0056] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0057] See Figures 2-33 As shown, the washing machine includes a cabinet 10, which has an integrated front panel 101. Specifically, the front panel 101 includes an observation section 1011 for mounting the observation window 50 and a control section 1012 for mounting the display module 2. The observation section 1011 and the control section 1012 are an integrated plate structure, and are connected vertically, forming the front end of the front panel 101. In a specific implementation, the display module 20 can be mounted only on the control section 1012, or the display module 20, the dispenser module 30, and the button module 40 can all be mounted on the control section 1012. The control section 1012 of the front panel 101 has a first opening 102 for mounting the display module 20, a second opening 103 for mounting the dispenser module 30, a third opening 104 for mounting the button module 40, and a mounting groove 105 for mounting the observation window 50. A circular clothing inlet 1051 is provided at the bottom of the mounting groove 105. The front panel of the washing machine is a one-piece front panel 101, which is a sheet metal part stamped from a single steel plate. In this way, the display module 20, distributor module 30, and button module 40 are directly assembled onto the front panel 101, eliminating the need for a control panel. This reduces the number of components in the washing machine, reduces the manufacturing of the front control panel, and reduces the installation of the control panel onto the front panel, which helps improve manufacturing and assembly efficiency. Furthermore, there is no gap between the control panel and the front panel, preventing water from seeping in through the gap, and reducing the gap also enhances the aesthetics of the washing machine. Compared to the method of assembling a sheet metal part with an injection-molded control panel on the front panel of the housing, using a one-piece sheet metal front panel 101 helps increase the structural strength of the housing 10.

[0058] Of course, for some washing machine models, where the strength requirements for the cabinet are not high, it is also possible to consider using a one-piece injection molded part for the front panel 101, or to have the entire cabinet 10 molded as a single piece.

[0059] The following describes the adjacent arrangement of the display module 20 and the viewing window 50:

[0060] See Figures 9-12The display module 20 and the observation window 50 are positioned adjacent to each other, meaning there are no other structural components between the front end of the display module 20 and the front end of the observation window 50. When the observation window 50 is closed, the lower front end of the display module 20 and the upper front end of the observation window 50 are adjacent to each other. Furthermore, this proximity is a surface fit, not a point fit. Specifically, the observation window 50 and the display module 20 each have a first edge end face 501 and a second edge end face 211 that are adjacent to each other. When the observation window 50 is closed, there is only a single gap between the first edge end face 501 and the second edge end face 211. By positioning the display module 20 and the observation window 50 adjacent to each other, the observation window 50 is positioned upwards relative to the display module 20 and has a second edge end face 501 adjacent to the display module 20. This allows the user to see the washing process of the clothes in the drum through the observation window 50 after viewing the display screen, simply by adjusting their downward gaze. This provides a wider field of view for observing the washing process and increases the convenience of observation for the user.

[0061] To maximize the length of the adjacent end faces of the two components, allowing the viewing window 50 to extend upwards as much as possible, the second edge end face 211 is set as the lower end face of the entire left-right direction of the front of the display module 20, and the first edge end face 501 is the end face on the outer edge of the viewing window 50 that is adjacent to and corresponds to the second edge end face 211. In other words, the entire lower end face of the front of the display module 20 is the second edge end face 211, which is set to have the maximum length in the left-right direction, making the lengths of the first edge end face 501 and the second edge end face 211 the longest possible.

[0062] A mounting groove 105 matching the observation window 50 is provided on the front panel 101. The mounting groove 105 has a circular basin-shaped structure, and a circular clothing inlet 1051 is provided at the bottom of the mounting groove 105. The mounting groove 105 and the clothing inlet 1051 are not coaxial. In order to reduce the modification of components and save costs, the opening size of the inner drum and the roller remains unchanged, and the user's comfortable observation area is also in the upper area. Therefore, the size of the clothing inlet 1051 remains unchanged. Only the area of ​​the observation window 50 is increased and moved upward, so that the increased visible area is in the upper part, which is conducive to achieving better results with the lowest cost. That is, the axis Y2 of the mounting groove 105 is set above the axis Y1 of the clothing inlet 105. Preferably, the axis of the mounting groove 105 is set directly above the axis of the clothing inlet 105, and the left and right symmetrical lines of the mounting groove 105 and the left and right symmetrical lines of the clothing inlet 105 are collinear.

[0063] See Figure 12As shown, the display module 20 and the observation window 50 are arranged vertically adjacent to each other. A backward bend 1052 is formed by extending backward and upward along the upper end wall of the mounting groove 105. By setting the backward bend 1052, the mounting groove 105 and the first opening 102 are connected, so that there are no other parts between the front part of the display module 20 and the front part of the observation window 50, making them adjacent to each other. The observation window 50 is set upward to the display module 20 and has a second edge end face 501 adjacent to the display module 20. After the user has finished viewing the display screen, they only need to adjust the downward angle of their gaze to see the washing status of the clothes in the drum through the observation window 50. This gives the washing machine a wider field of view for observing the washing status and increases the convenience of observation for the user.

[0064] See Figure 9 As shown, in a first configuration where the first edge end face 501 and the second edge end face 211 are adjacent, both the first edge end face 501 and the second edge end face 211 are arc-shaped surfaces. That is, the display module 20 is provided with a second edge end face 211 that mates with the arc-shaped outer edge of the observation window 50. The distance between the first edge end face 501 and the axis of the observation window 50 is equal to the radius of the observation window 50, and the axis of the observation window 50 is a horizontal line in the front-back direction. In other words, in order to make the length of the end face of the display module 20 that mates with the observation window 50 longer, the observation window 50 is set upward, and the lower front end face of the display module 20 is set to avoid the arc-shaped surface of the observation window 50.

[0065] See Figures 31-33 As shown, in a second configuration where the first edge face 501 and the second edge face 211 are adjacent, both the first edge face 501 and the second edge face 211 are horizontal planes. This means that the observation window 50 has a second edge face 211 that mates with the lower horizontal surface of the display module 20. The distance between the first edge face 501 and the axis of the observation window is less than the radius of the observation window 50. This allows for a longer length of the mating surface between the display module 20 and the observation window 50, enabling the observation window 50 to be positioned upwards. The upper end of the observation window 50 has a horizontal surface that avoids the display module 20. Since the lower front surface of the display module 20 is flat, the display module 20 is shielded from the notch in the mounting groove 105, thus eliminating the need for decorative elements.

[0066] The structural configuration of the rear curve 1052 and the decorative element 7 is described in detail below. See [link / reference]. Figures 2-12 ,as well as Figures 18-20 As shown.

[0067] See Figure 4 , Figure 6 and Figure 12As shown, a backward bend 1052 is formed by extending backward and upward along the upper end wall of the mounting groove 105. A first connecting transition arc surface 1053 is provided between the groove wall of the mounting groove 105 and the backward bend 1052. The first connecting transition arc surface 1053 is horizontally arranged in the left and right direction on the mounting groove 105, and the left and right sides of the first connecting transition arc surface 1053 are located at the outer edge of the mounting groove 105. That is, the portion of the mounting groove 105 above the horizontal plane where the first connecting transition arc surface 1053 is located extends backward; this connects the mounting groove 105 and the first opening 102, so that after the display module 20 and the observation window 50 are installed, the front end of the display module 20 and the front end of the observation window 50 are close together, which increases the area of ​​the observation window or moves the observation window upward, which helps to increase the user's viewing range of the washing situation, especially increasing the viewing area diagonally above the washing machine, increasing the convenience of user observation; and the setting of the backward bend 1052 helps to form support for the display module and improve the stability of the display module; resulting in the formation of a notch 1054 in the mounting groove 105. Specifically, the mounting groove 105 is basin-shaped and includes a vertically arranged groove bottom 1055 and a groove sidewall 1056 arranged outward and forward along the groove bottom 1055. The first connecting transition arc surface 1053 is connected to the groove sidewall 1056, that is, it bends backward on the groove sidewall 1056 so that the rear extension 1022 provides support for the middle and rear part of the display module 20.

[0068] See Figure 6 and Figure 12 As shown, after the rearward extension of the bend 1052, a notch 1054 is formed in the mounting groove 105. Although the notch area is small, the internal structure of the casing 10 can still be seen from the front of the washing machine after opening the observation window 50. Therefore, a decorative piece 7 is provided to fill the notch 1054 formed by the rearward bend 1052. The inner end face of the decorative piece 7 matches the inner end face of the mounting groove 105, and the decorative piece 7 is located in front of the rearward bend 1052.

[0069] See Figure 8 and Figure 12As shown, the decorative element 7 is adjacent to the mounting groove 105 at the first connecting transition arc surface 1053. The decorative element 7 is used to fill the gap 1054 formed by the rearward bending of the upper end of the groove sidewall 1056. Therefore, the decorative element 7 extends rearward and downward, and the lower end of the decorative element 7 is positioned adjacent to the first connecting transition arc surface 1053, so that the decorative element 7 and the mounting groove 105 cooperate to form a space for accommodating the observation window 50. Furthermore, since the first connecting transition arc surface 1053 is bent backward, the lower end of the decorative element 7 can abut against the first connecting transition arc surface 1053, which is beneficial to the tightness of the fit between the decorative element 7 and the first connecting transition arc surface 1053. Preferably, a receiving groove 71 matching the first connecting transition arc surface 1053 is provided on the decorative part 7, and the first connecting transition arc surface 1053 fits into the receiving groove 71. The receiving groove 71 serves two purposes: firstly, it reduces the thickness of the lower end of the decorative part 7, facilitating its fit with the wall of the mounting groove 105; secondly, it ensures a tight fit between the decorative part 7 and the first connecting transition arc surface 1053, increasing the stability of the decorative part 7. The lower end of the decorative part 7 also has a downward-extending edge 72 that covers the front side of the mounting groove 105 wall, and the edge 72 gradually decreases in thickness downwards, making the fit between the decorative part 7 and the mounting groove 105 more reliable.

[0070] See Figure 23 As shown, the decorative piece 7 is fixed to the display module 20, which has a front frame 21. The front end of the decorative piece 7 is located on the rear side of the front frame 21. The display module 20 has a display bracket 2, which includes the front frame 21 and a cylindrical body 22 extending rearward along the front frame 21. The front end of the decorative piece 7 is located on the rear side of the front frame 21. The plane containing the front edge of the mounting groove 105 is parallel to the plane containing the front edge of the decorative piece 7 and is positioned one in front of the other.

[0071] See Figures 18-20As shown, the back of the decorative panel 7 is provided with a support platform 73, on which multiple decorative positioning posts 74 extend upward. The display module 20 has positioning holes 26 that match the decorative positioning posts 74, with the decorative positioning posts 74 located within the positioning holes 26. This means that the decorative panel 7 is brought upward towards the display module 20 so that the decorative positioning posts 74 are installed into the positioning holes 26. Then, a fastening structure is provided between the decorative panel 7 and the display bracket 2 of the display module 20 to fix the decorative panel 7 to the display module 20. The axis of the decorative positioning posts 74 is perpendicular to the axis of the first fastening structure 75 provided on the decorative panel 7. This vertical positioning and fastening improves fixing efficiency while ensuring stability after fixing. Multiple reinforcing ribs 76 are also provided along the back of the decorative panel 7 in a vertical direction, with the support platform 73 and the reinforcing ribs 76 alternating. The support platform 73 improves the structural strength of the positioning posts 74 and facilitates their upward placement, while the reinforcing ribs 76 further enhance the structural strength of the decorative panel 7.

[0072] The following describes the assembly of the display module 20 with the front panel 101. See [link / reference] Figures 2-4 , Figures 11-15 ,as well as Figures 21-30 As shown.

[0073] To facilitate the assembly, maintenance, and disassembly of the display module 20, it is preferable to adopt a front-mounted design, with the button module 40 being installed and removed as a single unit. This means it is installed from the front of the washing machine to the rear, allowing for easy removal of the display module as a single unit from the front when maintenance is needed. The module can be moved outwards, providing sufficient operating space and improving disassembly efficiency. In this embodiment, the front panel 101 is a one-piece sheet metal component, or a one-piece sheet metal front panel. This requires the display module 20 to be mounted and fixed on the sheet metal component. However, the sheet metal component itself is relatively thin, limiting the available mounting positions and the availability of openings, further increasing the difficulty of fixing the display module 20.

[0074] See Figure 3 ,as well as Figures 11-13As shown, the display module 20 is fixed to the first opening 102 via a front mounting method. The upper edge of the front panel 101 has a rearwardly bent top edge 106, which extends rearward along the upper edge of the control unit 1012. The top edge 106 is part of the top surface of the washing machine. A downwardly bent top flange 107 is provided along the rear end of the top edge 106, and the display module 20 is fixedly mounted to the top flange 107. The top flange 107 is fixed to the rear of the display module 20, and combined with the support provided by the first opening 102, this improves the stability of the display module. Specifically, the display module 20 has multiple rearwardly extending display fixing posts 23, which are fixed to the top flange 107 by fasteners. Preferably, the display fixing posts 23 are located at the upper part of the display module 20, and screws are passed through screw holes in the top flange 107 and then fixed to the display fixing posts 23. The display fixing post 23 is set only on the upper part of the display module 20. First, the upper display fixing post 23 is fixed on the top flange 107 near the top folded edge 106, which is beneficial for fastening or disassembling the fasteners. Second, it can prevent the top flange 107 from being lengthened in the vertical direction, thus avoiding affecting the arrangement space of other components. It also helps to reduce material costs.

[0075] In other embodiments, display fixing posts can be provided at the lower or side of the display module 20, and the width of the top flange 107 in the vertical direction can be widened to fix the top flange 107 to display fixing posts in other parts.

[0076] For the fixing of the display module 20, a three-layer fixing method is used from the front to the back. The fixing with the top flange 107 is the rear fixing of the display module 20, and the snap-fit ​​fixing at the first opening 102 is the front fixing of the display module 20. Specifically, multiple first opening flanges 1021 extending rearward are provided along the edge of the first opening 102, and a snap-fit ​​positioning structure is provided between the display module 20 and the first opening flanges 1021; the front end of the display module 20 is snap-fit ​​fixed, which can be directly snapped in during the installation of the display module 20, which helps to improve installation efficiency.

[0077] See Figure 4 and Figure 24As shown, the locking and positioning structure includes a second claw 221 protruding outward on the display module 20, and a first locking plate 10211 bent inward on the first opening flange 1021, extending inward towards the axis of the first opening 102 and outward away from the axis of the first opening 102. The first locking plate 10211 and the second claw 221 are matched and locked together. Preferably, the first locking plate 10211 is provided on the first opening flange 1021 on the left and right sides of the first opening 102, and the second claw 221 is provided on the left and right sides of the display bracket 2 of the display module 20. A limiting strip 222 is provided on the display module 20 in front of the second claw 221. The limiting strip 222 stops in front of the first card plate 10211. That is, the first card plate 10211 is located between the limiting strip 222 and the second claw 221. The limiting strip 222 is used to limit the installation of the display module 20. Two guide edges 223 are provided at both ends of the limiting strip 222, which extend backward and are far apart from each other, for guiding when the second claw 221 is engaged.

[0078] In other implementations, second claws can be provided on all four first folded edges of the first opening 102 to achieve engagement of the display module 20 on the four sides of the first opening 102.

[0079] See Figure 4 and Figure 12 As shown, in this embodiment, the display module 20 and the observation window 50 are arranged vertically adjacent to each other. A rearward bend 1052 is formed by extending rearward and upward along the upper end wall of the mounting groove 105, and a rear extension 1022 is formed by continuing to extend rearward along the rearward bend 1052. The rear extension 1022 is used to define and support the display module 20. By setting the rearward bend 1052, the mounting groove 105 and the first opening 102 are connected, so that there are no other components between the front part of the display module 20 and the front part of the observation window 50, making them adjacent to each other. The observation window 50 is positioned upward at the display module 20 and has a second edge end face 501 adjacent to the display module 20. This allows the user to see the washing status of the clothes in the drum through the observation window 50 after viewing the display screen, simply by adjusting the downward angle of their gaze. This provides the washing machine with a wider viewing range for observing the washing process, increasing the convenience of observation for the user. By setting the rear extension 1022, the rear extension 1022 is positioned relatively far back, so that the rear extension 1022 is supported in the middle and rear part of the display module 20, which is conducive to forming strong support for the display module 20 and also conducive to the stability of fixing the lower end of the display module to the rear extension 1022.

[0080] See Figure 3 and Figure 4As shown, the middle part of the display module 20 is fixed by the support between the rear extension 1022 and the lower part of the display module 20. To increase the fixation of the rear extension 1022 for the display module 20, the rear extension 1022 includes a horizontally arranged extension body 10220 and an opening flange 10221 extending upward along the rear end of the extension body 10220. The dimensions of the extension body 10220 in the front-back direction gradually decrease from its left and right sides towards the center. That is, the interface between the rear extension 1022 and the rear bend 1052 is located in the horizontal plane where the extension body 10220 is located, and is an arc shape with a rearward convexity in the middle. The extension body 10220 provides support for the display module 20, ensuring that the rear extension 1022 provides sufficient support for the display module 20. At the same time, it is necessary to ensure that the rear bend 1052 transitions to the rear extension 1022 through bending at different positions at the front and back.

[0081] See Figure 4 , Figure 12 ,as well as Figure 24 As shown, a first locking hole 10222 is provided on the rear extension 1022. The first locking hole 10222 spans the extension body 10210 and the opening flange first locking hole 10222, that is, part of the first locking hole 10222 is provided on the extension body 10210 and the other part is provided on the opening flange first locking hole 10222. The display module 20 is provided with a rearwardly extending first locking claw 24, which is matched with the first locking hole 10222. The first locking hole 10222 is provided on the extension body 10210 mainly to avoid deformation when the first locking claw 24 is engaged. By setting the first locking claw 24 and the first locking hole 10222 to engage, the display module 20 can achieve the engagement of the first locking claw 24 and the first locking hole 10222 during the installation process, which helps to improve assembly efficiency. The first claw 24 has a rearwardly extending first insert plate 241, a first claw portion 242 disposed on the first insert plate 241, and a stop block 243 protruding from the first insert plate 241 for blocking the first opening flange first locking hole 10222. The stop block 242 is located in front of the first claw portion 242, and the first insert plate 241 passes through the first locking hole 10222. During the installation of the display module 20, the display module 20 is installed from front to back into the first opening 102 and pushed backward so that the first insert plate 241 passes through the first locking hole 10222; and continues to be pushed backward so that the first claw part 242 on the first insert plate 241 elastically deforms and passes through the first locking hole 10222. When the first claw part 242 elastically returns to its original position, it stops at the rear end of the first locking hole 10222; at the same time, the stop block 243 stops at the front side of the first locking hole 10222 on the opening flange, so that the display module 20 can no longer be pushed backward. In this way, the lower end of the display module 20 is locked and fixed at the first locking hole 10222.

[0082] During the installation of the display module 20, the display module 20 is installed from the front end of the housing into the first opening 102, and then pushed backward. A locking and positioning structure is provided between the display module 20 and the first opening flange 1021, so that the display module 20 is locked at the first opening 102. At the same time, the first claw 24 at the bottom of the display module 20 is locked with the opening flange 10221. During the process of pushing the display module 20 backward into place, the locking and positioning structure located on the left and right front parts is locked and fixed, and the first claw 24 located at the lower middle part is locked and fixed with the opening flange 10221. Then, fasteners pass through the top flange 107 and are fixed to the display fixing post 23. This double triple-layer fixation of the display module 20 in the front and rear directions helps to improve the stability of the fixation. Moreover, the locking and fixing during the assembly process of the display module 20 can be completed directly during the installation of the display module 20, which helps to improve the installation efficiency. The fixing of the fasteners is located on the rear side, which helps to improve the firmness after fixation.

[0083] The installation method of the display module 20 of the washing machine described above includes the following installation steps:

[0084] A. Assemble the various components of the display module 20 into a single unit.

[0085] B. Install the display module 20 from the front end of the housing into the first opening 102, and push the display module 20 backward to lock it in place.

[0086] Specifically, a locking and positioning structure is provided between the display module 20 and the first opening flange 1021, so that the display module 20 is locked at the first opening 102; at the same time, the first claw 24 at the lower part of the display module 20 is locked with the opening flange 10221.

[0087] C. The display module 20 is secured to the top flange 107 from the rear using fasteners.

[0088] Specifically, a display fixing post 23 is provided on the upper part of the display module 20, and screws pass through the screw holes opened on the top flange 107 and are fixed to the display fixing post 23.

[0089] See Figure 14 and Figure 15As shown, in order to reduce the assembly gap between the display module 20 and the front panel 101, the front end of the display module 20 is provided with multiple outwardly extending first edging edges 212, at least one of which covers the outside of the first opening 102. When describing the display module 20, the direction closer to the center line in the front-rear direction of the display module 20 is considered inside, and the opposite direction is considered outside. By setting the outwardly extending first edging edges 212, the gap between the display module 20 and the first opening 102 is made to be outwardly inclined, which helps to reduce the gap between the two. Furthermore, the first edging edges 212 cover the outside of the first opening 102, thus obscuring the gap between the display module 20 and the first opening 102, making the gap difficult to see from the front. The display module 20 has a front frame 21 and a display screen 1 fixed to the front end of the front frame 21. The front frame 21 has multiple first edging edges 212 extending forward and covering the outside of the display screen 1. Specifically, four first edging edges 212 are provided on the front frame 21, one on top, one on the bottom, and one on the left and right. Multiple first opening flanges 1021 extending backward are provided along the edge of the first opening 102, and the first opening flanges 1021 are connected to the front plate 101 by a transition arc surface 1025.

[0090] There are several possible fit methods between the first edge band 212 and the transition arc surface 1025. See [link / reference] Figure 14 and Figure 15 The first type of surface fit method is described, in which a edging groove 2121 matching the transition arc surface 1025 is provided on the first edging 212, and the transition arc surface 1025 is partially or entirely located within the edging groove 2112; this allows the edging groove 2112 to cover the horizontal gap between the display module 20 and the horizontally set first opening folded edge 1021, so that the fit between the display module 20 and the first opening 102 at the front end is the fit between the first edging 212 and the transition arc surface 1025, and the fit gap at the front end is in a forward and outward direction, making it difficult for the user to notice the assembly gap between the display module 20 and the front panel 101 from the front of the washing machine; by setting the edging groove 2121 to accommodate the transition arc surface 1025, the fit between the first edging 212 and the transition arc surface 1025 is a surface fit, increasing the fit area and effectively preventing water droplets from seeping in. The second method is a line fit, in which the outer end face of the first edge 212 is set as an inclined extension surface that extends forward and outward, and the transition arc surface 1025 is partially or entirely located on the rear side of the inclined extension surface, so that the fitting gap at the front end is in the forward and outward direction, making it difficult for the user to notice the assembly gap between the display module 20 and the front panel 101 when in front of the washing machine. The fit between the first edge 212 and the transition arc surface 1025 is a line fit.

[0091] A sealing element 8 is provided between the display module 20 and the first opening 102. The configuration of the sealing element 8 is described below. (See attached image.) Figures 11-17 As shown.

[0092] See Figure 15 and Figure 17 As shown, the seal 8 has a sealing body 81 that seals with the display module 20, and a sealing lip 82 that extends obliquely outward along the sealing body 81. A guide groove 83 is formed between the sealing body 81 and the sealing lip 82. By setting the sealing lip 82 to extend obliquely outward along the sealing body 81, the thickness of the sealing lip 82 is relatively thin compared to the sealing body 81. This facilitates the elastic deformation of the sealing lip 82 during installation, so that the sealing lip 82 is in a deformed state after installation. The force of the elastic deformation of the sealing lip 82 acts on the display module 80 and the first opening 102 that it contacts, which helps to ensure the tightness of the seal 8. Furthermore, the guide groove 83 formed between the sealing body 81 and the sealing lip 82 allows water that seeps in from the gap between the display module 20 and the first opening 102 to be guided through the guide groove 83 after reaching the seal 8, avoiding the accumulation of water at the seal 8 and reducing the risk of water seeping in through the seal 8. The sealing lip 82 is designed to be thinner in the outward direction, which further facilitates the elastic deformation of the sealing lip 82.

[0093] See Figure 14 , Figure 16 and Figure 24 As shown, the display module 20 has a display bracket 2, which includes a front frame 21 and a cylindrical body 22 extending rearward along the front frame 21. The cylindrical body 22 extends horizontally rearward, and a seal 8 is fitted on the outside of the cylindrical body 22. The front frame 21 is located in front of the seal 8. Preferably, the seal 8 and the front frame 21 are spaced apart to form a drainage groove 88. The outward inclined extension direction of the sealing lip 82 matches the assembly direction when the display module 20 is installed into the first opening 102, and the outward inclined direction of the sealing lip 82 is opposite to the moving direction when the display module 20 is installed into the first opening 102. This makes the angle between the sealing lip 82 and the sealing body 81 tend to decrease after the display module 20 is installed into the first opening 102. The outer end of the sealing lip 82 deforms towards the sealing body 81 under the pressure of the first opening flange 1021, which helps to increase the contact area between the first opening flange 1021 and the sealing lip 82 and improve the sealing performance.

[0094] In this embodiment, the display module 20 is front-mounted, with a rearwardly extending first opening flange 1021 along the edge of the first opening 102. The sealing lip 82 seals with the first opening flange 1021, and the sealing lip 82 extends forward and outward. The guide channel 83 has a top guide channel 831 connected to it, and side guide channels 832 located on the left and right sides. The lower end of the side guide channel 832 is an open end 834 for water droplets to flow downward. That is, the sealing lip 82 is only provided on the top and left and right sides of the sealing member 8, which is conducive to forming the open end 834, so that the water flowing into the guide channel 83 can flow out after reaching the open end 834 along the guide channel, avoiding the accumulation of water in the guide channel 83. After the display module 20 is installed into the first opening 102, it mainly prevents water from entering from the top gap and the gaps on the left and right sides, so as to avoid reaching the inside of the display module 2 and causing damage to the electrical components. Even if water enters from the lower gap of the display module 20, it will not reach the display module. Therefore, no sealing lip 82 is provided at the lower end of the seal 8 to the top gap.

[0095] See Figure 17 As shown, the guide groove 83 has a first groove surface 835 that is inclined forward and inward, a second groove surface 836 that is inclined forward and outward, and an arc-shaped connecting groove surface 837 that connects the first groove surface 835 and the second groove surface 836. The first groove surface 835 is located on the sealing body 81, the second groove surface 836 is located on the sealing lip 82, and a portion of the arc-shaped connecting groove surface 837 is located on the sealing body 81 and a portion of the sealing lip 82. By setting a second groove surface 36 that is forward and outward, when water reaches the gap between the display module 20 and the first opening 102, the water moves backward along the first opening folded edge 1021. After reaching the second groove surface 836, the water will flow along the inclined surface of the second groove surface 836. At the top guide groove 831, after the water reaches the second groove surface 836, it will flow along the inclined surface of the second groove surface 836 to the arc-shaped connecting groove surface 837, and then flow towards the first groove surface 835. At the side guide groove 832, the water can flow directly backward along the second groove surface 836 to the open end 834 and flow out of the seal 8.

[0096] The seal 8 has an outer end face 84 that is inclined forward and outward, and an inner end face 85 that is parallel to the cylinder 22. The cylinder 22 has multiple outwardly protruding and rearwardly extending display fixing posts 23 for fixing the display module 20. The seal is located between the display fixing posts 23 and the front frame 21. The sealing body 81 has a forward-extending protrusion 86 located between two adjacent display fixing posts 23. The protrusion 86 increases the contact area with the cylinder 22, improves sealing, facilitates support of the sealing lip 82, and aids in the circumferential positioning of the seal 8.

[0097] The following describes the structural setup of display module 20. (See also...) Figures 21-30 As shown.

[0098] See Figure 22 and Figure 23 As shown, the display module 20 includes a display bracket 2, a display screen 1 disposed at the front end of the display bracket 2, a display panel 3 located behind the display screen 1, and a flow plate 5 located behind the display panel 3. The flow plate 5 is tilted backward relative to the display panel 3 in the upward direction. By positioning the flow plate 5 behind the display panel 3, the display panel 3 and the flow plate 5 are stacked in the front-to-back direction, avoiding the need to separately position the display panel 3 and the flow plate 5 in the left and right directions of the washing machine. This saves space in the left and right directions, allowing the display screen 3 to be larger in the left and right directions for easier user operation. Furthermore, it eliminates the need for separate protection for the display panel 3 and the flow plate 5, reducing the need for a protective back cover and saving costs. The tilted placement of the flow plate 5 relative to the display panel 3 creates a large tilt angle between the flow plate 5 and the vertical plane, making it easier and more efficient to connect the connectors to the flow plate.

[0099] In this embodiment, see Figure 2 As shown, the display module 20 is set on the front face of the drum washing machine, the display screen 1 has a slight backward tilt angle, the display plate 3 is set parallel to the display screen 1, and the flow plate 5 is set behind the display plate 3. After the display module 20 is installed from front to back, multiple plug-in terminals are then plugged into the flow plate 5. Therefore, by setting the flow plate 5 to be tilted relative to the display plate 3, the backward tilt angle of the flow plate 5 is slightly larger, which allows for plug-in operations in the forward and downward directions, which is conducive to observation and improves the quality and efficiency of plug-in.

[0100] Regarding the angle between the display panel 3 and the flow plate 5, if the angle is too large, the structure will be less compact, the front-to-back dimension of the display module 20 will be too large, occupying a large amount of space in the front-to-back direction, and a large angle will also be detrimental to the insertion operation. Preferably, the angle between the display panel 3 and the flow plate 5 is set to 4° to 15°, more preferably 5° to 10°; preferably, the angle between the flow plate 5 and the vertical plane is set to 20° to 40°, more preferably 20° to 30°.

[0101] The display panel 3 includes an integrally formed display panel body, a lamp holder located on the front side of the display panel body, and a display film attached to the front side of the lamp holder. The display panel 3 is fixed to the display panel bracket 2. In order to fix the flow board 5, the flow board bracket 4 is also fixed to the display panel bracket 2. It also has a rear cover 6 located behind the flow board 5. The rear cover 6 is fixed to the display bracket 2 and stops at the rear of the flow board bracket 4. An extension opening 68 is formed between the display bracket 2 and the rear cover 6 for the upper end of the flow board bracket 4 to extend. By setting the upper end of the flow board bracket 4 to extend, the plug-in terminals can be plugged into the display module 20 assembled as a whole.

[0102] See Figure 22 , Figure 24 and Figure 25 As shown, the display bracket 2 has a frame 21 and a cylindrical body 22 extending rearward along the frame 21. The upper part of the flow plate bracket 4 is disposed adjacent to the upper wall of the cylindrical body 22, that is, the front end of the upper part of the flow plate bracket 4 is close to the upper wall of the cylindrical body 22, and the rear end of the upper part of the flow plate bracket 4 is close to the rear cover 6, that is, the upper part of the flow plate bracket 4 extends upward from between the display bracket 2 and the rear cover 6. The display panel 3 is fixed inside the cylinder 22. The flow plate support 4 is tilted downwards and forwards, so that the lower part of the flow plate support 4 extends into the cylinder 22. Multiple protruding top posts 411, which are positioned behind the display panel 3, are provided on the flow plate support 4. By tilting the lower part of the flow plate support 4 forwards, the upper part of the flow plate support 4 is also tilted backwards. The top posts 411 are used to fix the display panel 3, thus achieving the purpose of tilting the flow plate 5 relative to the display panel 3 and also serving to fix the display panel 3. The flow plate support 4 is arranged parallel to the flow plate 5, and the flow plate 5 and the rear cover 6 are also arranged parallel to each other.

[0103] See Figure 25 and Figure 26 As shown, the flow plate support 4 includes a support body 41 and a limiting structure 42 disposed above the support body 41. The limiting structure 42 is used to fix the plug-in terminals connected to the flow plate 5. The limiting structure 42 is located above the flow plate 5. After the plug-in terminals are plugged into the flow plate 5, the plug-in terminals are fixed on the limiting structure 42. Specifically, the limiting structure 42 includes a limiting frame 421 with upper and lower openings and limiting claws 422 disposed on the limiting frame 421 for locking the plug-in terminals; it also includes multiple vertically arranged partition plates 423 that divide the limiting frame 421 into multiple partition spaces. The limiting claws 422 and the partition plates 423 are alternately arranged, or in other words, each limiting claw 422 is located in a partition space, and the plug-in terminals are fixed in the partition space.

[0104] For fixing the process plate bracket 4 and the display bracket 2, a rearwardly extending display fixing post 23 is provided on the outer side of the display bracket 2. A slot 231 is provided on the display fixing post 23. The process plate bracket 4 is provided with an outwardly protruding locking protrusion 424 that matches the slot 231. The locking protrusion 424 is located inside the slot 231. Preferably, the upper end of the cylindrical body 22 of the display bracket 2 is provided with two left and right display fixing posts 23. The display fixing posts 23 protrude rearward from the rear end face of the cylindrical body 22 along the upper end of the cylindrical body 22. A lower open slot 231 is provided on the display fixing post 23. The front end face of the slot 231 contacts the rear end face of the cylindrical body 22. The locking protrusion 421 extends upward along the left and right sides of the limiting frame 421 to form a locking protrusion. This makes the upper part of the process plate bracket 4 closely adjacent to the upper wall of the cylindrical body 22. The upper end of the process plate bracket 4 and the display bracket 2 are secured by a locking protrusion 424 and a locking slot 231, and the lower end is secured by a fastener. The process plate bracket 4 is provided with an outwardly extending fixing ear 412, which is fixed to the display bracket 2 by screws. This is beneficial to the firmness of the fixation.

[0105] See Figure 24 ,as well as Figures 27-30 As shown, for the assembly between the back cover 6 and the display bracket 2, a limiting structure is provided between the display bracket 2 and the back cover 6. The limiting structure is a first limiting plate disposed on one of the display bracket 2 and the back cover 6, and engaging with the corner of the other. Specifically, the first limiting plate can be disposed on the display bracket 2, engaging with the corner of the back cover 6; or the first limiting plate can also be disposed on the back cover 6, engaging with the corner of the display bracket 2. This allows the first limiting plate to be disposed on only one component of the display bracket 2 and the back cover 6, utilizing the corner of the other component to engage with the first limiting plate, which simplifies the structure and improves the stability of the engagement. By setting a limiting structure, assembly efficiency is improved, as is the stability after the back cover 6 and the display bracket 2 are fixed in place.

[0106] Taking the example of setting a first limiting plate 63 on the back cover 6, the back cover 6 is provided with multiple first limiting plates 63, including at least one pair of first limiting plates 63 arranged diagonally. The diagonally arranged first limiting plates 63 cooperate with the two diagonal portions of the display bracket 2, which helps to improve the stability of the fixation. Preferably, the back cover 6 is provided with four first limiting plates 63 extending forward, which cooperate with the four corners of the display bracket 2 to achieve limiting.

[0107] The display bracket 2 has a front frame 21 and a cylindrical body 22 extending rearward along the front frame 21. The rear cover 6 has a rear cover plate 61 and an extension plate 62 extending forward along the edge of the rear cover plate 61. A first limiting insert 63 extending rearward from the extension plate 62 is provided on the inner side of the extension plate 62. The first limiting insert 63 extends into the cylindrical body 22, and the front end face of the rear cover plate 61 fits against the rear end face of the cylindrical body 22, which has the effect of positioning and limiting.

[0108] A plug-in fixing structure and a snap-fit ​​fixing structure are provided between the display bracket 2 and the back cover 6. These structures are positioned opposite each other on the left and right sides, meaning that a plug-in fixing structure on one side and a snap-fit ​​fixing structure on the other. When the back cover 6 is assembled to the display bracket 2, the limiting structure positions the back cover 6 against the display bracket 2 and provides support and fixation after assembly. The plug-in fixing structure and the snap-fit ​​fixing structure then secure the back cover 6 to the display bracket 2. Preferably, two plug-in points and one snap-fit ​​point are provided; this three-point fixing method is more conducive to stability after fixing.

[0109] The locking and fixing structure includes a rearwardly extending locking plate 25 on the display bracket 2, and a protruding slot 64 on the extension plate 62 of the rear cover 6 for accommodating the locking plate. A protruding third claw 251 is provided on the locking plate 25, and a locking strip 641 engaging with the third claw 251 is provided in the slot 64; wherein a locking insertion opening 642 for the locking plate 25 to extend is formed around the locking strip 641 and the slot 64; a protruding limiting edge 252 is provided on the locking plate 25, the limiting edge 252 being located in front of the third claw 251, and the locking strip 641 being located between the limiting edge and the third claw 251. By setting the locking plate 25, the locking strip 641, and the locking socket 642, the locking plate 25 is locked into the locking socket 642; and the slot 64 is set to protrude outward, which is conducive to accommodating the inserted locking plate 25. That is, the locking plate 25 is inserted into the slot 64, and the rear end protrudes from the locking socket 642, so that the third claw 251, the limiting edge 252 and the locking strip 641 cooperate to allow the back cover 6 and the display bracket 2 to withstand the force in the front and rear directions. The locking plate 25 is located in the slot 64 so that the back cover 6 and the display bracket 2 can withstand the force in the vertical direction.

[0110] In order to increase the stress strength at the slot 64, a second limiting plate 65 extending forward is provided on the extension plate 62. The second limiting plate 65 is arranged adjacent to the slot 64 and is inserted into the cylinder 22 of the display bracket 2.

[0111] The cylindrical body 22 of the display bracket 2 is provided with a rearwardly extending insertion edge 224. The insertion and fixing structure is provided with multiple insertion posts 66 on the rear cover 6 and insertion holes 225 that match the insertion posts on the insertion edge 224. The insertion posts 66 are inserted into the insertion holes 225. Preferably, two insertion holes 225 are provided on one side of the cylindrical body 22. A locking plate 25 is provided on the other side of the cylindrical body 22.

[0112] See Figure 10 and Figure 11 As shown, for the installation of the front panel 101, the housing 10 also includes left and right side panels 108 and a tabletop 109, with the top flange 107 arranged adjacent to the tabletop 109. Preferably, the upper surface of the top flange 106 is flush with the upper surface of the tabletop 109. A crossbeam 110 is fixedly installed on the top of the left and right side panels 108, and the front panel 101 is hung on the crossbeam 110 via the top flange 107. For the installation and fixing of the front panel 101, first, the crossbeam 110 is fixedly connected to the left and right side panels 108, then the front panel 101 is hung on the crossbeam 110, and finally the front panel 101 and the crossbeam 110 are fixed. The operation is simple, and the crossbeam 110 provides a certain degree of support and fixation for the front panel 101, enhancing the stability of the overall structure of the washing machine. This suspension installation method ensures both assembly clearance and assembly strength.
