Description

Technical Field

[0001] This invention relates to the field of washing machines, and more specifically, to a washing machine door structure and a washing machine. Background Technology

[0002] Washing machines typically have a door to seal the opening. There is often a gap between the door and the surrounding structure of the washing machine opening, which can trap clothing or other objects. Furthermore, the door is usually made of metal, as is the structure around the washing machine opening. This can lead to friction between the metal structures of the door and the washing machine opening during opening and closing, potentially causing damage to the door and / or the washing machine structure. To cover the gap between the door and the surrounding structure and prevent friction, a sealing structure can be installed between the door and the washing machine, protecting both the door and the washing machine.

[0003] Current patents disclose washing machine doors comprising an outer frame, a glass door, and an inner frame, with foam material injected into the sealed space between these components to ensure a tight connection. Other patents disclose a ring-shaped reinforcing member superimposed between the inner and outer frames, with the reinforcing member matching and connecting to the inner frame. This reinforcing member improves overall structural strength, prevents glass door deformation, and ensures a secure fit. In essence, current patents primarily focus on tightly securing the various structures within the door, but lack a structure that conceals the gap between the door and the washing machine, providing protection and isolation between them.

[0004] In summary, there is a need for a washing machine door structure that can use a sealing device to cover the gap between the door and the washing machine, preventing clothes and other items from getting stuck in the gap; and that the sealing structure can prevent friction between the door and other structures near the opening of the washing drum, thus protecting the door and the structures near the opening of the washing drum.

[0005] In view of the above problems, this invention is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a washing machine door structure that, when installed on the washing machine, can cover the gap between the door and other structures of the washing machine, preventing clothes from getting caught in the gap; and can also prevent the door structure from rubbing against other structures of the washing machine and causing damage during the opening and closing process.

[0007] This invention provides a washing machine door structure, including a door body, with a door seal protruding outward from the closed end face of the door body. The door seal can seal the gap between the washing machine door body and the washing machine, preventing clothes from getting caught in the gap; furthermore, the door seal can also prevent the door body from rubbing against other structures on the washing machine during opening and closing.

[0008] Furthermore, the specific structure of the door seal is as follows: the door seal is a strip structure extending along a ring, and the cross-section of the door seal is a hollow "U"-shaped groove. The opening of the "U"-shaped groove engages with the closed end face of the door and extends outward from the door body; at least one end of the opening of the "U"-shaped groove is fixed to the door body. Because the "U"-shaped groove of the door seal protrudes outward, it can isolate and protect the door body when the door body is installed on the washing machine.

[0009] Furthermore, reinforcing ribs extending towards the center and spaced apart from the bottom of the "U"-shaped groove are provided on the inner and / or outer peripheral walls of the "U"-shaped groove; preferably, reinforcing ribs extending towards the center are provided at the same height on the inner and outer peripheral walls of the "U"-shaped groove, with a gap between the extended ends of the two reinforcing ribs. By providing reinforcing ribs, the strength of the "U"-shaped door seal can be improved.

[0010] Furthermore, the inner peripheral wall of the "U"-shaped groove is provided with a protrusion extending away from the bottom of the "U"-shaped groove and away from the door body. The protrusion has a sealing rib that protrudes radially along the door body and is parallel to the closed end face of the door body. Preferably, the protrusion is located on the inner peripheral side of the "U"-shaped groove, and the sealing rib is located at the end of the protrusion away from the bottom of the "U"-shaped groove and extends towards the outer peripheral side of the "U"-shaped groove. In addition to the "U"-shaped housing, the door seal also includes the outwardly extending sealing rib, which serves to block and isolate the door body from other structures of the washing machine.

[0011] Furthermore, the door body consists of an inner frame, an outer frame, and a glass door. A mounting groove is formed between the inner and outer frames, and the glass door is embedded within this groove. The side of the inner frame facing away from the outer frame is a closed end face. The opening of the "U"-shaped groove engages with the closed end face of the inner frame. By engaging the "U"-shaped groove of the door seal with the outer end face of the inner frame, the door seal can isolate other structures outside the inner frame.

[0012] Furthermore, at least a portion of the closed end face of the inner frame serves as a mounting surface, and at least a portion of the outer frame abuts against the mounting surface. Screws are positioned at the abutting points to fasten the inner and outer frames. A U-shaped groove forms a screw guard, with the screw head fixed to the mounting surface. The opening of the screw guard engages with the mounting surface, creating a closed space where the screw head is positioned. The inner and outer frames are secured with screws, and the U-shaped housing of the door seal acts as a screw guard, effectively protecting the screws.

[0013] Furthermore, the washing machine door structure also includes a support frame supporting the inner frame, outer frame, and glass door. The support frame includes a mounting plate that supports the mounting surface. Screw holes are provided on the mounting plate, through which screws securing the inner and outer frames pass and fix the mounting plate. The sidewall of the screw protector abuts perpendicularly to the outer end face of the mounting plate, and the opening of the screw protector engages with the outer end face of the mounting plate that does not contact the inner frame. Preferably, the mounting plate abuts parallel to the mounting surface, and a vertically bent wall is provided on the mounting surface. A gap exists between the mounting plate and the vertical wall along the parallel direction, and the inner peripheral wall of the screw protector is embedded in the gap. A vertically bent limiting plate is provided at the end of the mounting plate away from the vertical wall, and the outer peripheral wall of the screw protector abuts parallel to the limiting plate. Placing the screw protector at the bottom of the mounting plate effectively prevents the mounting plate from colliding with other structures of the washing machine during the opening and closing of the glass door, especially preventing the screws on the mounting plate from colliding with other structures of the washing machine.

[0014] Furthermore, the inner frame includes a base plate that is perpendicularly connected to the vertical wall and parallel to the glass door. The vertical wall and base plate of the inner frame, together with the outer frame, form a mounting groove. The door seal wraps around the vertical wall and base plate of the inner frame and extends into the mounting groove. The door seal forms a groove-shaped structure inside the mounting groove, and the glass door is embedded within the groove-shaped structure. The side walls of the inner and outer frames, located within the mounting groove and parallel to the circumference of the glass door, abut against the groove-shaped structure. When there is a gap between the inner and outer frames and the glass door, the glass door can be securely fixed by wrapping it with the groove-shaped structure formed by the door seal within the mounting groove.

[0015] Furthermore, another form of the washing machine door is as follows: the vertical wall of the inner frame is connected to an inner frame support that abuts against the inner end face of the glass door, and an outer frame support that abuts against the outer end face of the glass door is provided on the outer frame, with the glass door sandwiched between the inner frame support and the outer frame support; the door seal only includes a screw protective cover, and the inner peripheral wall of the screw protective cover abuts against the vertical wall of the inner frame in parallel.

[0016] Another objective of this invention is to provide a washing machine in which the aforementioned door structure is provided, thereby concealing the gap between the door and other components of the washing machine and preventing friction between the door and other components during opening and closing. Specifically, the washing machine provided by this invention includes a washing drum, the opening of which is provided with the aforementioned door structure. The door of the door structure covers the opening of the washing drum, and a gap exists between the door and the washing drum. A door seal of the door structure seals this gap.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1) The washing machine door structure provided by this invention features a reasonably designed door seal. This design ensures that during the opening and closing of the door, the door with fixed glass does not rub against other parts of the washing machine, thus protecting both the door and the machine. Furthermore, the door seal effectively blocks the gaps between the door and other parts of the washing machine, preventing clothes from getting caught in these gaps.

[0019] 2) The inner and outer frames are connected by screws. The door sealing structure provided by this invention includes a screw protective cover. This cover protects the exposed screw heads outside the inner frame. Furthermore, the well-designed screw protective cover allows the inner and outer frames to be pressed together after closing, ensuring the glass door is securely fixed between them. The screw protective cover provided by this invention has a simple "U"-shaped groove structure, which can be fastened to form a closed space. The screw heads are positioned within this closed space for protection.

[0020] 3) The washing machine door structure of this invention also includes a support frame to support the integrated structure of the inner frame, outer frame, and glass door, allowing the washing drum to be connected to the integrated structure. Furthermore, the mounting plate of the support frame supports the mounting surface of the inner frame; that is, the mounting plate is supported from the bottom, and the screw guard can be directly fastened to the bottom of the mounting plate, thus preventing the mounting plate from rubbing or colliding with other structures of the washing machine.

[0021] 4) The inner frame and mounting plate of this invention have a reasonable structural arrangement. The vertical wall of the inner frame abuts against the inner peripheral wall of the screw protector, and the limiting plate of the mounting plate abuts against the outer peripheral wall of the screw protector, so that the screw protector is snapped between the inner frame and the mounting plate. That is, the reasonable arrangement of the inner frame and the mounting plate facilitates the fixing of the screw protector.

[0022] 5) This invention provides two specific door seal structures. The door seal can wrap around the inner frame and extend into the mounting groove. By wrapping the glass door with a groove-shaped structure formed within the mounting groove, the glass door is protected. Sealing ribs on the door seal isolate other structures of the washing machine. Alternatively, when the inner and outer frames directly clamp the glass door, the door seal may only include a screw protector, and the "U"-shaped groove bottom of the screw protector can be directly used to isolate other structures of the washing machine without the need for sealing ribs. This makes the door seal structure simpler and saves materials.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] The washing machine drum needs an opening for loading clothes, and a door is installed at the opening to cover and seal it. The door is mounted on the drum, and gaps may exist between the door and other parts of the washing machine, potentially causing clothes to get caught in these gaps. Furthermore, the door may rub against other parts of the washing machine during opening and closing. Therefore, a sealing device is needed in the door structure to seal these gaps and prevent friction between the door and other parts of the washing machine during opening and closing. Specifically... Figure 1 As shown, a door seal 5 protruding outward is provided on the closed end face 13 of the door. The door seal 5 seals the gap and isolates the door from other structures of the washing machine, preventing the door from rubbing against other structures of the washing machine during opening and closing.

[0032] To facilitate observation of the inside of the washing drum, a glass door 1 is typically installed at the opening to shield it. This glass door 1 is usually held within a mounting frame. Since the mounting frame is typically metal, and the structure surrounding the washing drum opening is also metal, the metal mounting frame directly rubs and collides with the metal structure around the washing drum opening during opening and closing, potentially damaging the mounting frame and / or the surrounding structure. Therefore, it is essential to install a door seal 5 on the mounting frame. This seals the gap between the mounting frame and other components of the washing machine, and isolates the mounting frame from these components, preventing frictional damage.

[0033] The washing machine door structure provided in this embodiment is shown in the figure. It includes a glass door 1 that is disposed at the opening of the washing drum and correspondingly covers the opening. The glass door 1 is fixed in a mounting frame. There is a gap between the mounting frame and the structure around the opening of the washing drum. A door seal 5 is disposed in the gap to isolate the mounting frame from the structure around the opening of the washing drum. The door seal 5 is a relatively soft strip structure, which can be made of materials such as rubber or plastic. By setting the door seal 5, the mounting frame and the structure around the opening of the washing drum will not directly rub against each other due to the gap between them, thus protecting the mounting frame and the structure around the opening of the washing drum. Alternatively, the door seal 5 can be disposed on the mounting frame but not in the gap. The door seal 5 simply adheres to the mounting frame, achieving the effect of protecting the mounting frame.

[0034] The mounting frame includes an inner frame 2 and an outer frame 3. The glass door 1 is embedded in the mounting groove 4 formed between the inner frame 2 and the outer frame 3. The door seal 5 covers the outer end face of the inner frame closest to the washing drum opening, thus isolating the outer end face of the inner frame from the structure surrounding the washing drum opening. The specific structure of the mounting frame includes the inner frame 2 and the outer frame 3. According to the distance from the washing drum wall from farthest to closest, the order is: outer frame 3, glass door 1, inner frame 2. That is, the inner frame 2 is the structure of the mounting frame closest to the washing drum wall, so the door seal 5 can cover the outer end face of the inner frame, thus achieving the effect of isolating the mounting frame from the washing drum. And specifically as follows... Figure 1 As shown, a flange 22 is often provided around the opening of the washing tub. The flange 22 structure is the structure of the mounting frame on the washing tub closest to the opening. That is, during the opening and closing of the glass door 1, the outer end face of the inner frame is most likely to rub against the flange 22. Therefore, the door seal 5 at least covers the part of the outer end face of the inner frame opposite to the flange 22.

[0035] As shown in the figure, the portion of the outer end face of the inner frame opposite to the flange 22 is the mounting surface 7. At least a portion of the outer frame 3 is in contact with the mounting surface 7. Screws 6 are installed at the contact points to secure the inner frame 2 and the outer frame 3. The inner frame 2 and the outer frame 3, parallel to the circumference of the glass door 1, are in contact with each other. The inner frame 2 and the outer frame 3 are separated at their contact points, forming a gap that constitutes a mounting groove 4. The glass door 1 is fixed within the mounting groove 4. The inner frame 2 and the outer frame 3 extend parallel to the circumference of the glass door 1. The glass door 1 is embedded within the mounting groove 4 between the inner frame 2 and the outer frame 3, allowing the inner frame 2 and the outer frame 3 to limit the movement of the glass door 1 in a direction perpendicular to its circumference, i.e., clamping the glass door 1 in a direction perpendicular to its circumference. Specifically... Figure 1 As shown, the inner frame 2 and outer frame 3 have abutting and fitting positions parallel to the circumference of the glass door 1. The inner frame 2 and outer frame 3 are fixed at these abutting and fitting positions, for example, by screws, clips, or other fastening structures. Furthermore, the inner frame 2 and outer frame 3 are separated at the abutting and fixing positions to form a gap, which constitutes a mounting groove 4 in which the glass door 1 is embedded. That is, the structure of the inner frame 2 and outer frame 3 is similar to a clip in daily life. The inner frame 2 and outer frame 3 are fixed at the abutting and fitting positions, and then separate from these positions, allowing the separated portions to be used to clamp other objects. Because the inner frame 2 and outer frame 3 are fixed at the abutting and fitting positions, to ensure a fixed connection between them, the door seal 5 can abut and press against the abutting and fitting position of the inner frame 2 and outer frame 3. That is, the structure of the door seal 5 is used to press the inner frame 2 and the outer frame 3 to a fixed position, so as to ensure that the inner frame 2 and the outer frame 3 are firmly fixed.

[0036] In this embodiment, the inner frame 2 and the outer frame 3 are fixed together by screws 6; that is, screws 6 are installed at the position where the inner frame 2 and the outer frame 3 abut and fit together, and screws 6 fasten the inner frame 2 and the outer frame 3. The inner frame 2 includes a mounting surface 7 that fits against the outer frame 3, and the screw head 8 of the screw 6 is fixed to the mounting surface 7. The door seal 5 includes a screw protective cover that can correspondingly surround the screw head 8. The screw head 8 of the screw 6 is fixed to the outer end face of the mounting surface 7, and the screw protective cover is fastened to the outer end face of the mounting surface 7. The screw protective cover has a reasonable structure, which can cover the screw head 8 that is exposed on the outside of the screw 6 and protect the screw head 8. Furthermore, when the glass door 1 is normally fastened, the structure of the screw protective cover can press the inner frame 2, thereby pressing the position where the inner frame 2 and the outer frame 3 abut and fit together, ensuring the tight fixation of the inner frame 2 and the outer frame 3. Furthermore, the screw protective cover can be correspondingly installed in the above-mentioned gaps to achieve the effect of correspondingly sealing the gap between the mounting frame and the washing drum.

[0037] like Figure 1As shown, the screw protector has a hollow, U-shaped groove 9 in cross-section. The opening of the screw protector engages with the mounting surface 7, meaning the opening 29 of the U-shaped groove is blocked by the mounting surface 7. The U-shaped groove of the screw protector 7 engages with the mounting surface 7, forming a closed space. The screw head 8 of the screw 6 is positioned within this closed space, allowing it to be protected by the screw protector. The inner and outer periphery sidewalls 10 of the U-shaped groove 9 of the screw protector abut perpendicularly to the mounting surface 7. When the glass door 1 is in the engaged state, these abutments correspond to the positions where the inner frame 2 and outer frame 3 are pressed together. In other words, the sidewalls 10 of the screw protector limit the inner frame 2 in a direction perpendicular to the mounting surface 7. The door seal 5 can be fixed in position by snap-fitting, screw fastening or adhesive, so that the side wall 10 on the screw cover keeps the inner frame 2 and the outer frame 3 in a fixed position, thereby ensuring the stable fixation of the inner frame 2, the outer frame 3 and the glass door 1.

[0038] As shown in Figure 1, the inner frame 2, outer frame 3, and glass door 1 are assembled into a single structure through splicing and installation. The washing machine door structure also includes a support frame 11 fixed to the washing drum. The support frame 11 supports the integrated structure of the inner frame 2, outer frame 3, and glass door 1. The support frame 11 ensures that the integrated structure of the inner frame 2, outer frame 3, and glass door 1 can be fixedly connected to the washing drum, thus guaranteeing that the integrated structure of the inner frame 2, outer frame 3, and glass door 1 is fixed at the door position on the washing drum.

[0039] like Figure 1 As shown, the support frame 11 includes a mounting plate 12, which supports the mounting surface 7. Along the distance from the washing machine door, from farthest to near, the outer frame 3, glass door 1, and inner frame 2 are sequentially arranged. In the integrated structure of the outer frame 3, glass door 1, and inner frame 2, the mounting surface 7 of the inner frame 2 is the bottom wall closest to the washing machine door. Therefore, the support frame 11 only needs to support the mounting surface 7 to support the entire integrated structure; that is, the mounting plate 12 on the support frame 11 supports the mounting surface 7 from the bottom. The mounting plate 12 has screw holes, and the screws that fasten the inner frame 2 and outer frame 3 pass through these screw holes to fix the mounting plate 12. Thus, by providing screw holes on the mounting plate 12, the screws that fasten the inner frame 2 and outer frame 3 pass through these screw holes, achieving the effect of fixing the mounting plate 12, inner frame 2, and outer frame 3 together. Therefore, a single screw 6 can be used to fix the mounting plate 12, inner frame 2, and outer frame 3.

[0040] This arrangement results in a mounting plate 12 below the mounting surface 7 of the inner frame 2, allowing the screw protector to be directly fastened to the mounting plate 12. Since the mounting plate 12, inner frame 2, and outer frame 3 are connected as a single unit, the screw protector 9 can be directly fastened to the bottom of the mounting plate 12. This screw protector then presses the mounting plate 12, similarly achieving the effect of pressing the inner frame 2 and outer frame 3, ensuring the structural stability of the inner frame 2, outer frame 3, and glass door 1. Specifically, the opening of the screw protector fastens the mounting plate 12 without contacting the outer end face 13 of the inner frame 2. The inner and outer peripheral sidewalls 10 of the screw protector abut perpendicularly to the outer end face 13 of the mounting plate 12, with the abutting portion correspondingly pressing the mounting plate 12 against the inner frame 2. As mentioned earlier, when the support frame 11 is not set, the side wall 10 of the screw cover presses against the mounting surface 7 of the inner frame 2. However, after the support frame 11 is set, there is also a mounting plate 12 structure under the mounting surface 7 of the inner frame 2, so the screw cover can be directly fastened to the bottom of the mounting plate 12.

[0041] like Figure 1 As shown, when the screw cover is fastened to the mounting plate 12, if a partial limiting structure is provided for the screw cover 9, the screw cover can be better limited, which is beneficial for fixing the screw cover. Figure 1 As shown, the mounting plate 12 abuts parallel to the mounting surface 7. A vertically bent vertical wall 14 is provided on the mounting surface 7. A gap 15 exists between the mounting plate 12 and the vertical wall 14 along the extending direction. The inner peripheral wall 16 of the screw protector is fitted into the gap 15. That is, the inner frame 2 includes a vertical wall 14 that can limit the inner peripheral wall 16 of the screw protector. The gap 15 between the mounting plate 12 and the vertical wall 14 along the extending direction of the mounting plate 12 is precisely used to engage the inner peripheral wall 16 of the screw protector. The inner peripheral wall 16 of the screw protector is embedded in the gap 15, allowing the inner peripheral wall 16 of the screw protector to be limited and abutted by the mounting plate 12 and the vertical wall 14, thereby ensuring that the inner peripheral wall 16 of the screw protector is well limited and fixed. Furthermore, the top of the inner peripheral wall 16 can directly abut against the mounting surface 7 of the inner frame 2, pressing against the mounting surface 7 of the inner frame 2. Figure 1 As shown, a vertically bent limiting plate 17 is provided at one end of the mounting plate 12 away from the vertical wall 14, and the outer peripheral wall 18 of the screw protector abuts against the limiting plate 17 parallel to it. That is, the limiting plate 17 provided on the mounting plate 12 can also limit the outer peripheral wall 18 of the screw protector. In other words, through the structure of the mounting plate 12 and the inner frame 2 provided in this embodiment as shown in Figure 1, the screw protector can be snapped between the limiting plate 17 and the vertical wall 14 of the inner frame 2, thereby ensuring that the screw protector is well fixed.

[0042] like Figure 1As shown, the inner frame 2 includes a base plate 19 that is perpendicularly connected to the vertical wall 14 and parallel to the glass door 1. The vertical wall 14, the base plate 19, and the outer frame 3 of the inner frame 2 form a mounting groove 4, in which the glass door 1 is embedded. The vertical wall 14 and the base plate 19 of the inner frame 2 can form an "L"-shaped structure, which can limit the glass door 1 in both vertical and horizontal directions. The "L"-shaped structure, together with the outer frame 3, forms the mounting groove 4. The door seal 5 wraps around the vertical wall 14 and the base plate 19 of the inner frame 2 and extends into the mounting groove 4. By wrapping the vertical wall 14 and the base plate 19 of the inner frame 2 with the door seal 5, the door seal 5 can effectively press the inner frame 2, thereby ensuring that the inner frame 2 and the outer frame 3 remain firmly fixed. The door seal 5 forms a groove-shaped structure 20 inside the mounting groove 4, in which the glass door 1 is embedded. Figure 1 As shown, the groove structure 20 is C-shaped, and the glass door 1 is perfectly embedded in the opening of the groove structure 20 along its circumference. The glass door 1 is surrounded and protected by the groove structure 20. Furthermore, the inner frame 2 and outer frame 3, located within the mounting groove 4, have their sidewalls parallel to the circumference of the glass door 1 abutting against the groove structure 20. That is, the sidewalls of the inner frame 2 and outer frame 3, parallel to the circumference of the glass door 1, can limit the groove structure 20 in a direction perpendicular to the circumference of the glass door 1, so that the groove structure 20 is snapped and limited between the inner frame 2 and the outer frame 3, thereby ensuring that the glass door 1 is well-limited in a direction perpendicular to its circumference and ensuring the stability of the glass door 1 installation.

[0043] like Figure 1 As shown, the washing machine door structure also includes a washing drum flange 21. The washing drum flange 21 has a flange 22 closest to the mounting plate 12, that is, the boundary of the integrated structure of the washing drum flange 21 closest to the support frame 11, the inner frame 2, and the outer frame 3 is the flange 22. A sealing rib 23 protruding outward and abutting against the flange 22 is provided on the door seal 5. The specific structure of the sealing rib 23 is that it extends outward from the inner peripheral wall 16 of the "U"-shaped groove 9, forming a protrusion 31 that protrudes from the bottom 26 of the "U"-shaped groove and extends away from the door body. The protrusion 31 is provided with a sealing rib 23 that protrudes radially along the door body and is parallel to the closed end face of the door body. Preferably, the protrusion is located on the inner peripheral side of the "U"-shaped groove 9, and the sealing rib 23 is located at the end of the protrusion away from the bottom 26 of the "U"-shaped groove and extends outward. The sealing rib 23 isolates the integrated structure of the washing drum flange 21, inner frame 2, outer frame 3, and mounting plate 12, thus isolating the washing drum flange 21 and preventing water from flowing from the flange 21 to other locations and affecting other structures, such as the visibility of the glass door. It also prevents friction between the flange 22 and the mounting plate 12 during the opening and closing of the glass door 1, which could damage these components.

[0044] like Figure 1 As shown, in addition to the circumferential fixing points along the glass door 1, the inner frame 2 and outer frame 3 can also be fixed along a direction perpendicular to the axial direction of the glass door 1. For example, a first vertical wall 27 perpendicular to the circumferential direction of the glass door 1 can be provided on the inner frame 2, and a second vertical wall 28 perpendicular to the circumferential direction of the glass door 1 can be provided on the outer frame 3. The first vertical wall 27 and the second vertical wall 28 abut against each other. That is, the provision of the first vertical wall 27 and the second vertical wall 28 also achieves the effect of fixing the inner frame 2 and the outer frame 3, so that the inner frame 2 and the outer frame 3 are limited in the direction parallel to the circumferential direction of the glass door 1, thereby facilitating the fixing of the inner frame 2 and the outer frame 3.

[0045] The washing machine door structure provided in this embodiment, through the reasonable design of the door seal 5, ensures that the mounting frame fixing the glass door 1 will not rub against the structure around the washing drum opening during the opening and closing process, preventing damage to the glass door 1 and the structure around the washing drum opening. Furthermore, the door seal 5 seals the installation gap between the door structure and the washing machine, preventing clothes and other items from getting caught in the gap. The reasonable arrangement of the inner frame 2, outer frame 3, glass door 1, and door seal 5 ensures that all parts of the washing machine door structure are securely fixed. In particular, the structural design of the door seal 5 ensures that the inner frame 2 and outer frame 3 securely clamp the glass door 1, protects the screws 6, and prevents water flow from the washing drum flange from affecting the washing machine door structure.

[0046] Example 2

[0047] This embodiment is based on the above embodiment, such as... Figure 2 As shown, another form of washing machine door structure is provided. The washing machine door structure provided in this embodiment is the same as described in Embodiment 1, also having an inner frame 2, an outer frame 3, a glass door 1, a support frame 11, and a door seal 5. It also uses the mounting groove 4 formed between the inner frame 2 and the outer frame 3 to fix the glass door 1, uses the support frame 11 to integrally fix the inner frame 2, the outer frame 3, and the glass door 1 to the washing drum, and uses screws 6 to fix the inner frame 2, the outer frame 3, and the support frame 11. The difference lies in the specific structure of the door seal 5, and the specific structures of the inner frame 2 and the outer frame 3 for fixing the glass door 1 are different.

[0048] like Figure 2As shown, the vertical wall 14 of the inner frame 2 is connected to the inner frame support 24, which abuts against the inner end face of the glass door 1. The outer frame 3 is provided with an outer frame support 25, which abuts against the outer end face of the glass door 1. The glass door 1 is clamped between the inner frame support 24 and the outer frame support 25. That is, the structure of the inner frame 2 and the outer frame 3 provided in this embodiment has an end face perpendicular to the circumferential direction that can fit the glass door 1. The inner frame 2 and the outer frame 3 respectively clamp the glass door 1 using their own inner frame support 24 and outer frame support 25, thereby ensuring that the glass door 1 is well limited and fixed, and the door seal 5 can fix the glass door 1 without extending into the mounting groove 4. The mounting groove 4 can also be provided with... Figure 2 The sealing ring shown further ensures the airtightness of the glass door 1.

[0049] Since the door seal 5 does not need to extend into the mounting groove 4, meaning the door seal 5 only includes a screw protector, the structure of the screw protector is relatively simple. For example... Figure 2 As shown, the inner peripheral wall 16 of the screw cover abuts parallel to the vertical wall 14 of the inner frame 2, and the inner peripheral wall 16 of the screw cover can be limited by the vertical wall 14 of the inner frame 2. The outer peripheral wall 18 of the screw cover is limited by the limiting plate 17 on the mounting plate 12 as described in Embodiment 1. The "U"-shaped groove bottom 26 of the screw cover abuts against the flange 22 of the washing drum flange 21 closest to the mounting plate 12. That is, the structure of the door seal 5 differs from that described in Embodiment 1, which uses a sealing rib 23 to isolate the washing drum flange 21; instead, it directly utilizes the structure of the screw cover to isolate the washing drum flange 21. The "U"-shaped groove bottom 26 of the screw cover abuts against the flange 22 of the washing drum flange 21, allowing the "U"-shaped groove bottom 26 of the screw cover to isolate the washing drum flange 21 and prevent water that may overflow from the washing drum flange 21 from affecting other structures. Furthermore, as... Figure 2 As shown, the door seal 5 isolates the flange 22, preventing friction between the mounting frame and / or the flange 22 structure that fixes the glass door 1 during opening and closing. Figure 1 As shown in the diagram, the door seal 5 structure in Embodiment 1 has a gap between the sealing rib 23 and the "U"-shaped groove bottom of the screw protector, which could cause objects such as clothing to get stuck in the gap. However, in this embodiment, because the "U"-shaped groove bottom 26 of the screw protector directly abuts against the flange 22 of the washing drum flange 21, there is no gap between the screw protector and the washing drum flange 21, preventing objects from getting stuck. The screw protector also has... Figure 2 As shown, a reinforcing rib structure is provided for the screw 6, which improves the strength of the screw protective cover.

[0050] The washing machine door structure provided in this embodiment features a more rational design for the door seal 5. This eliminates the need for the door seal 5 to extend into the mounting groove 4; it only requires a screw protector, reducing the material used and simplifying its structure. Furthermore, the screw protector's design is reasonable. The "U"-shaped groove bottom 26 of the screw protector abuts against the flange 22 of the washing drum flange 21, effectively isolating the washing drum flange 21 and preventing gaps between the screw protector and the washing drum flange 21, thus preventing objects from being trapped.

[0051] This embodiment also provides a washing machine, particularly a holeless washing machine, which includes an inner drum, and the opening of the inner drum can be provided with the washing machine door structure as described above. This washing machine door structure allows the inner drum to be opened and closed by opening and closing the glass door 1. Furthermore, because the door structure at the inner drum opening is reasonably designed, it can prevent the mounting frame of the glass door 1 from rubbing against the surrounding structure of the washing drum opening during the opening and closing process, thus protecting the structure at the glass door 1 with the door seal 5.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
