Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, specifically to a front door panel with decorative panels and a drum washing machine. Background Technology

[0002] The front door panel of a drum washing machine is typically made using sheet metal bending technology. During the stamping and bending process, multiple holes, assembly gaps, and structural partitions are inevitably created at the top. These structures serve two purposes: firstly, to accommodate the requirements of the stamping and bending process (such as stress relief and easy positioning); and secondly, to provide installation space for electronic components (such as door sensors) and mechanical components (such as hinge connectors). To conceal these exposed structures for safety (avoiding scratches and preventing the intrusion of foreign objects / moisture) and to achieve a unified and refined overall appearance, a decorative panel is usually installed at the top of the front door panel.

[0003] Currently, most drum washing machine decorative panels in the industry are fixed using a single snap-fit ​​connection structure. This involves using plastic snaps on the bottom of the decorative panel to engage with corresponding slots on the top sheet metal base of the front door panel or the machine body. However, this fixing method requires considerable manual force to engage the snaps and slots, and incorrect snap positioning can easily damage them, leading to assembly difficulties and potential component damage.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a front door panel with a decorative panel and a drum washing machine, which aims to solve the problem that the existing decorative panel is only connected to the front door panel by a snap-fit, which leads to difficult assembly and easy damage to the parts.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: A front door panel with decorative trim, comprising: The front door panel body and the decorative panel body disposed on the top of the front door panel body; The front door panel body includes a top plate, a plurality of first slots horizontally spaced on the top plate, and two snap-fit ​​parts; The decorative panel body includes an abutment plate, a plurality of sliding buckles and two limiting buckles arranged horizontally at intervals at the bottom of the abutment plate, and a baffle plate arranged at the bottom of the abutment plate; The sliding buckle is located in the first slot and can slide longitudinally within the first slot to engage or disengage with the first slot; the limiting buckle slides longitudinally with the engaging part to engage or disengage with the engaging part; the baffle is connected to the top plate through a locking member to lock the sliding buckle and the first slot, and the limiting buckle and the engaging part in the engaged state.

[0007] Furthermore, the front door panel body also includes a front panel, side panels disposed on both sides of the front panel, a bottom plate disposed at the bottom of the front panel, and a fixed bending edge disposed at the bottom of the top panel; The fixed bending edge is provided with multiple fixed posts, and the fixed posts are provided with threaded holes inside. The baffle is provided with multiple through holes, and the through holes correspond one-to-one with the fixed posts.

[0008] Furthermore, a second slot is provided at the connection between the fixed bent edge and the top plate, the opening of the second slot facing away from the front plate, and a first buckle is provided at the bottom of the abutment plate, the first buckle cooperating with the second slot.

[0009] Furthermore, the sliding buckle is L-shaped.

[0010] Furthermore, the top of the top plate is provided with multiple limiting grooves, and the bottom of the abutment plate is provided with a limiting plate, which abuts against the side wall of the limiting groove away from the front plate.

[0011] Furthermore, a mating plate is provided on one side of the baffle, and the mating plate, the baffle, and the abutment plate together form a sealing groove with an opening, and a sealing strip is provided in the sealing groove.

[0012] Furthermore, the bottom of the abutment plate is provided with a groove, and a support rib is provided in the groove, the support rib abutting against the surface of the top plate.

[0013] Furthermore, the snap-fit ​​portion is formed by the gap between the top plate and the side plate, and a supporting bent edge is provided on the side of the side plate near the top plate, the supporting bent edge being located at the bottom of the top plate.

[0014] Furthermore, the abutment plate has chamfers on the side near the front plate and on both sides near the two side plates.

[0015] A drum washing machine includes the aforementioned front door panel with decorative trim.

[0016] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the sliding buckle can slide longitudinally within the first slot, and the limiting buckle and the locking part slide longitudinally together, eliminating the need for a "hard clamp," significantly reducing the manual operation effort and avoiding buckle breakage or sheet metal slot deformation caused by excessive force. At the same time, multiple sliding buckles and the first slot, and two limiting buckles and the locking part form a "multi-point guide," which can reduce the risk of buckle damage due to "oblique insertion" even if there are production tolerances in the front door panel sheet metal. This solves the assembly difficulty problem, reduces the probability of component damage, and improves the assembly yield. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In view of the shortcomings of the prior art, this embodiment provides a front door panel with a decorative panel and a drum washing machine, as detailed below: As attached Figure 1 Appendix Figure 2 Appendix Figure 3 and attached Figure 4As shown, a front door panel with a decorative panel includes a front door panel body 1 and a decorative panel body 2; the decorative panel body 2 is disposed on the top of the front door panel body 1; the front door panel body 1 includes a top plate 11, a plurality of first slots 14 and a latching part 111, the top plate 11 is located on the top of the front door panel body 1, the plurality of first slots 14 are horizontally spaced on the top, and two latching parts 111 are symmetrically disposed at both ends of the top plate 11; the decorative panel body 2 includes an abutment plate 21, a plurality of sliding buckles 22, two limiting buckles 23 and a baffle 24, the plurality of sliding buckles 22 and a baffle 24 are provided. The buckles 22 are horizontally spaced at the bottom of the abutment plate 21 and protrude from the ground of the abutment plate 21, corresponding one-to-one with the first slots 14. The sliding buckles 22 can slide vertically in the first slots 14 to engage or disengage with the first slots 14. The limiting buckles 23 and the locking parts 111 slide vertically together. The baffle 24 is connected to the top plate 11 through the locking member, which can lock the sliding buckles 22 and the first slots 14, and the limiting buckles 23 and the locking parts 111 in the engaged state, thereby restricting both and realizing the locking of the decorative panel body 2 and the front door panel body 1.

[0032] Among them, the sliding buckle 22 refers to the lateral (i.e., left-right direction of the front door panel) protruding from the bottom of the abutment plate 21. Specifically, it can be integrally injection molded. Its head has a barbed engagement end, which is adapted to the rectangular groove of the first slot 14. By sliding along the longitudinal direction of the first slot 14, the engagement position can be adjusted to achieve tight engagement or easy disengagement. The limiting buckle 23 is a barbed engagement end symmetrically distributed at both ends of the bottom of the abutment plate 21. The material is the same as the sliding buckle 22. Its laterally extending claws can form a sliding fit with the engagement parts 111 at both ends of the top plate 11 to limit the lateral displacement of the decorative panel body 2. The snap-fit ​​part 111 refers to the slot structure stamped at both ends of the top plate 11 (the slot can be formed by the gap between the top plate 11 and the side plates 13 on both sides, or an opening can be provided on the side of the top plate 11 away from the front plate 12, and the limiting buckle 23 slides in the opening). The slot faces inward (i.e., the rear side of the front door panel body 1), and the slot width is adapted to the thickness of the claw of the limiting buckle 23 to provide lateral limiting support. The baffle 24 is a plate-shaped structure that fits the surface of the top plate 11 and can be made of high-strength plastic. Its edge is provided with mounting holes adapted to the locking parts. The locking parts can be cross-slot countersunk screws, spring clips, or expansion pins. Screw connections are suitable for scenarios that require long-term fixation, while spring clips are suitable for disassembly and maintenance requirements.

[0033] Specifically, when assembling the decorative panel body 2, first align it with the top plate 11 of the front door panel body 1, aligning the sliding buckle 22 with the first slot 14 and the limiting buckle 23 with the engaging part 111. Push the abutment plate 21 horizontally (i.e., longitudinally, in the front-to-back direction of the front door panel): the sliding buckle 22 slides along the first slot 14 to a preset position, and the barbed end engages with the edge of the first slot 14; the claw of the limiting buckle 23 slides into the groove of the engaging part 111, and the bottom barbed end of the limiting buckle 23 engages with the bottom wall of the top plate 11, completing the initial positioning. Then continue pushing the decorative panel body 2 to abut the baffle 24 against the top, and connect it to the threaded hole or buckle seat of the top plate 11 through the mounting hole of the baffle 24. During assembly, the decorative panel 2 and the front door panel body 1 can be engaged manually without much force, and locked with screws.

[0034] Meanwhile, when the door opens and closes or the washing machine vibrates during operation, the barbed structure of the sliding buckle 22 prevents longitudinal and vertical separation, the limiting buckle 23 restricts lateral displacement, and the baffle 24, through the rigid constraint of the locking element, blocks the relative displacement between the sliding buckle 22 and the first slot 14, and between the limiting buckle 23 and the locking part 111, thus achieving a dual anti-loosening effect.

[0035] Compared to existing technologies, traditional decorative panels rely on a single plastic clip for engagement, requiring significant manual force to snap the clip into place. Furthermore, incorrect clip positioning can easily damage the clip, leading to assembly difficulties and potential component failure. This solution, through the adjustable design of the sliding clip 22, can accommodate varying assembly tolerances, effectively reducing the force required compared to fixed clips. Simultaneously, the sliding clip 22 and the limiting clip 23 engage under the guidance of the first slot 14 and the engaging part 111, preventing damage from forceful pushing.

[0036] The sliding buckle 22 can slide longitudinally within the first slot 14, and the limiting buckle 23 and the locking part 111 slide longitudinally together, eliminating the need for "hard locking" and greatly reducing the manual operation effort. This avoids buckle breakage or sheet metal slot deformation caused by excessive force. At the same time, multiple sliding buckles 22 and the first slot 14, and two limiting buckles 23 and the locking part 111 form a "multi-point guide". Even if there are production tolerances in the front door panel sheet metal, the risk of buckle damage due to "oblique insertion" can be reduced through sliding adaptation. This not only solves the assembly difficulty problem, but also reduces the probability of component damage and improves the assembly yield.

[0037] In this embodiment, as shown in the appendix Figure 4 and attached Figure 5As shown, the front door panel body 1 also includes a front panel 12, two side panels 13, a bottom panel, and a fixed bending edge 112; the two side panels 13 are bent and arranged on both sides of the front panel 12, and are perpendicular to the front panel 12 and the top panel 11; the bottom panel is arranged at the bottom of the front panel 12; the fixed bending edge 112 is arranged at the bottom of the top panel 11 and is formed by bending the top panel 11 downwards.

[0038] The fixed bending edge 112 is provided with multiple fixing posts 115, and the fixing posts 115 are provided with threaded holes. The baffle 24 is provided with multiple through holes, which correspond one-to-one with the fixing posts 115. Screws can be installed in the through holes, and the screws are threadedly engaged with the threaded holes to fix the fixed bending edge 112 to the baffle 24.

[0039] The front panel 12, two vertically arranged side panels 13, bottom panel, and top panel 11 together form a complete front door panel body 1 frame, which greatly improves the overall structural rigidity, reduces deformation during door opening and closing and equipment operation, and provides a stable base for the assembly of the decorative panel body 2. The fixed bending edge 112 formed by bending the bottom of the top panel 11 downwards provides an independent and solid assembly carrier for the baffle 24, avoiding the problem of being easily affected by assembly errors when relying on the surface of the top panel 11 for fixation. The fixing posts 115 on the fixed bending edge 112 correspond one-to-one with the through holes of the baffle 24, and form a rigid lock through the screw thread engagement, which can completely fix the engagement state of the sliding buckle 22 and the first slot 14, and the limiting buckle 23 and the locking part 111, significantly enhancing the connection stability, effectively resisting loosening caused by vibration and friction, while ensuring assembly accuracy and maintaining the core functions of decorative panel shielding and protection and integrated appearance for a long time.

[0040] In this embodiment, as shown in the appendix Figure 4 and attached Figure 7 As shown, a second slot 113 is provided at the connection between the fixed bending edge 112 and the top plate 11. Part of the second slot 113 is located on the fixed bending edge 112, and the other part is located on the top plate 11. The opening of the second slot 113 faces away from the front plate 12. A first buckle 25 is provided at the bottom of the abutment plate 21. The first buckle 25 can be located in the second slot 113 under the sliding of the abutment plate 21 and engage with it. Thus, the abutment plate 21 can engage with the top plate 11 not only at the front end but also at the rear end, thereby increasing the stability between the decorative panel body 2 and the top plate 11.

[0041] In this embodiment, as shown in the appendix Figure 9 As shown, the sliding buckle 22 is L-shaped. The L-shape allows the sliding buckle 22 to form a gap with the bottom wall of the abutment plate 21, which can be used to engage with the top plate 11.

[0042] In this embodiment, as shown in the appendix Figure 7As shown, the top of the top plate 11 is provided with multiple limiting grooves, and the bottom of the abutment plate 21 is provided with a limiting plate 26. The limiting plate 26 abuts against the side wall of the limiting groove 114 away from the front plate 12.

[0043] The sliding buckle 22 engages with the top plate 11 in a forward-facing direction, while the limiting plate 26 abuts against the side wall of the limiting groove 114 in a rearward-facing direction, achieving a front-to-back locking effect. In the initial state, the limiting plate 26 protrudes from the bottom wall of the abutment plate 21 and slides on the surface of the top plate 11 until the sliding buckle 22 engages with the top plate 11, and the limiting plate 26 is also located within the limiting groove 114.

[0044] The limiting groove at the top of the top plate 11 cooperates with the limiting plate 26 at the bottom of the abutment plate 21. Combined with the characteristic of the sliding buckle 22 engaging with the top plate 11 in the forward direction, the limiting plate 26 abuts against the side wall of the limiting groove away from the front plate 12 in the backward direction, forming a front-to-back two-way locking structure of "front locking and rear abutting", which completely blocks the displacement of the decorative panel body 2 in the front-to-back direction. In the initial state, the limiting plate 26 protrudes from the bottom wall of the abutment plate 21 and slides along the surface of the top plate 11. It can not only provide guidance for the assembly of the decorative panel and ensure that the sliding buckle 22 is accurately engaged, but also allow the limiting plate 26 to fall into the limiting groove after assembly to achieve limiting, further strengthening the connection stability between the decorative panel and the front door panel body 1, and effectively resisting the front-to-back loosening caused by the opening and closing of the door and equipment vibration.

[0045] In this embodiment, as shown in the appendix Figure 10 As shown, a mating plate 27 is provided on one side of the baffle 24. The mating plate 27 extends perpendicularly to the surface of the baffle 24 and cooperates with the baffle 24 and the abutment plate 21 to form a sealing groove 28 with the opening facing the rear. A sealing strip 29 is provided in the sealing groove 28 for sealing cooperation with the cabinet of the washing machine.

[0046] In this embodiment, as shown in the appendix Figure 8 and attached Figure 9 As shown, a groove 211 is provided at the bottom of the abutment plate 21, and a support rib 212 is provided in the groove 211. The support rib 212 abuts against the surface of the top plate 11.

[0047] The ribs can be designed as a crisscrossing grid or strips distributed along the direction of force, concentrating the weight of the decorative panel and external forces to key support points, improving the structure's resistance to deformation, and reducing fitting problems caused by flatness errors (local ribs can compensate for assembly gaps through minor deformation); at the same time, the ribs provide greater assembly tolerance, and a small number of foreign objects can be accommodated by the gaps between the ribs, preventing local lifting; finally, the functional expandability is better, the gaps between the ribs can form ventilation channels or wiring space, while reducing the contact area, reducing vibration transmission efficiency, and thus reducing operating noise.

[0048] In this embodiment, as shown in the appendix Figure 6 As shown, the snap-fit ​​part 111 has a gap between the top and the side plate 3. The side plate 3 is provided with a supporting bending edge 131 on the side near the top. The supporting bending edge 131 is located at the bottom of the top plate 11. The two can be welded together to improve the overall stability.

[0049] The supporting bent edge 131 is welded to the top plate 11 to form a rigid integrated structure. First, it strengthens the connection node between the side plate 13 and the top plate 11, preventing the connection from loosening due to high-frequency stress from the opening and closing of the door or equipment vibration, thus solving the hidden danger of easy deformation of the simple gap-type snap-fit ​​part 111. Second, the welded and fixed supporting bent edge 131 provides a precise and stable dimensional constraint for the gap of the snap-fit ​​part 111, ensuring that the limit buckle 23 can always form a suitable sliding fit with the gap, avoiding limit failure due to gap deformation. At the same time, the supporting bent edge 131 is also used to fix the top plate 11, preventing the top plate 11 from deforming and detaching from the limit buckle 23.

[0050] In this embodiment, the abutment plate 21 has chamfers on the side near the front plate 12 and on both sides near the side plates 13.

[0051] This application also provides a drum washing machine, including the aforementioned front door panel with a decorative panel.
