Description

Technical Field

[0001] This utility model belongs to the field of washing machine technology, specifically relating to a plastic decorative strip and door cover for a washing machine. Background Technology

[0002] Modern washing machine doors are no longer limited to plain plastic or glass covers; they now feature decorative strips in various colors, creating a richer color scheme. However, in the actual production process, the assembly of the plastic decorative strips with the door cover presents several challenges:

[0003] Problem 1: It is difficult to control the gap between the plastic decorative strip and the door frame, especially the gap between the two ends of the plastic decorative strip and the door frame is unstable.

[0004] Challenge Two: Plastic decorative strips are mostly long and narrow, making it difficult to balance both length and surface quality. This is mainly because during injection molding, increasing the injection pressure to control surface shrinkage results in longer strips; conversely, reducing the injection pressure to control length leads to more severe surface shrinkage. These factors result in decorative strips being either too long or too short, frequently exceeding tolerances and making assembly impossible.

[0005] Problem 3: After the plastic decorative strips are sprayed or electroplated, they often warp and twist, causing the middle part of the plastic decorative strip to not fit the door frame, affecting the glass assembly, and even causing gaps between the glass and the door frame / decorative strip.

[0006] To address the aforementioned issues, this utility model proposes a plastic decorative strip for a washing machine door cover and a door cover itself. Utility Model Content

[0007] The first objective of this invention is to provide a plastic decorative strip for a washing machine.

The two ends of the inner connecting wall are respectively provided with end limiting structures, and the two ends of the inner connecting wall are provided with middle limiting structures at intervals.

[0011] A further technical solution of this utility model is: the notch is a U-shaped notch.

[0012] The second objective of the utility model is achieved through the following technical solution:

[0013] A washing machine door cover, characterized in that: it includes a door cover frame, a cover plate and the aforementioned plastic decorative strip, the edge of the door cover frame is provided with a gap, and an end fitting limiting structure and a middle fitting limiting structure are provided near the gap, the end limiting structure and the middle limiting structure of the inner connecting wall of the plastic decorative strip are respectively fitted and connected with the end fitting limiting structure and the middle fitting limiting structure, the outer decorative wall fills the gap, and the cover plate is fixedly covered on the door cover frame.

[0014] A further technical solution of this utility model is as follows: the inner connecting wall end of the plastic decorative strip is provided with an end through hole, the end limiting structure of the plastic decorative strip includes a limiting slot and an end plate respectively provided at both ends of the end through hole, and the end fitting limiting structure of the door cover frame includes a limiting rib for engaging in the limiting slot and an end cantilever hook for hooking on the end plate.

[0015] A further technical solution of this utility model is as follows: a central through hole is provided between the two ends of the inner connecting wall of the plastic decorative strip; the central limiting structure of the plastic decorative strip includes spaced limiting waist holes and a central locking platform provided in the central through hole; the central fitting limiting structure of the door frame includes spaced limiting posts for passing through the limiting waist holes and spaced central cantilever hooks for hooking onto the central locking platform.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The plastic decorative strip of the washing machine of this utility model is provided with end limiting structures at both ends. The end limiting structures can be connected with the end limiting structures of the door frame, thereby limiting the position of both ends of the assembled plastic decorative strip, thereby better controlling the gap between the two ends of the plastic decorative strip and the two ends of the door frame, so that the gap after assembly is controllable and meets the design requirements.

[0021] (2) This utility model features notches spaced along the inner edge of the inner connecting wall of the plastic decorative strip. This has two advantages: First, during injection molding, these notches act as flow deceleration devices, causing the liquid injection molding material to flow faster at the outer decorative wall than at the inner connecting wall. The liquid injection molding material will first fill the cavity at the outer decorative wall and then the cavity at the inner connecting wall, effectively ensuring that the appearance surface (i.e., the outer decorative wall) does not shrink while maintaining the length dimension as required by the design. Second, these notches effectively divide the inner connecting wall, making the plastic decorative strip relatively softer (especially after surface electroplating), resulting in a better fit with the door frame during assembly. Therefore, this utility model can reduce the dimensional accuracy requirements for the plastic decorative strip. Attached Figure Description

[0036] This embodiment takes the plastic decorative strip and door cover of a top-loading washing machine as an example.

[0037] like Figure 1 and Figure 2 The plastic decorative strip 1 of the washing machine shown in this embodiment is a long strip with both ends bent inward. It is used to install on the front of the washing machine door cover for decoration, so that the washing machine door cover has a richer color scheme.

[0038] The plastic decorative strip 1 has an outer decorative wall 1.1 located on the periphery and an inner connecting wall 1.2 located on the back of the outer decorative wall 1.1 for connecting with the washing machine door cover. The outer decorative wall 1.1 and the inner connecting wall 1.2 are integrally injection molded, and the inner connecting wall 1.1 is perpendicular to the back of the outer decorative wall 1.2.

[0039] U-shaped notches 1.3 are provided at intervals along the inner edge of the inner connecting wall 1.2. In this embodiment, there are six U-shaped notches 1.3, but the number can be adjusted according to design requirements. During injection molding, the U-shaped notches 1.3 act as flow cut-off and deceleration mechanisms, causing the liquid injection molding material to flow faster at the outer decorative wall 1.1 than at the inner connecting wall 1.2. The liquid injection molding material will first fill the cavity at the outer decorative wall 1.1 and then fill the cavity at the inner connecting wall 1.2. This effectively ensures that the outer surface (i.e., the outer decorative wall) does not shrink while ensuring that the length dimension meets design requirements. Moreover, the U-shaped notches 1.3 effectively divide the inner connecting wall 1.2, making the plastic decorative strip 1 relatively soft (especially after surface electroplating), resulting in a better fit with the door frame 2 during assembly.

[0040] The inner connecting wall 1.2 has end limiting structures at both ends, and a middle limiting structure is arranged at intervals between the two ends. The specific structure of the end limiting structure in this embodiment is as follows: an end through hole 1.6 is provided at the end of the inner connecting wall 1.2, and the end limiting structure includes limiting slots 1.8 and end locking platforms 1.7 respectively provided at both ends of the end through hole 1.6. The specific structure of the middle limiting structure in this embodiment is as follows: a middle through hole 1.9 is provided between the two ends of the inner connecting wall 1.2, and the middle limiting structure includes limiting waist holes 1.5 arranged at intervals and a middle locking platform 1.10 provided in the middle through hole 1.9. This embodiment specifically provides six limiting waist holes 1.5 and three middle locking platforms 1.10.

[0041] like Figures 3 to 8 The washing machine door cover shown in this embodiment includes a door cover frame 2, a cover plate 4, double-sided adhesive tape 3, a door cover buffer pad 5, screws 6, and the aforementioned plastic decorative strip 1. The door cover frame 2 is made of plastic, and the cover plate 4 is made of glass.

[0042] In this embodiment, the middle part of the door frame 2 is a window 2.2, and a gap 2.1 is provided at the front of the door frame 2. The size of the gap 2.1 matches the size of the outer decorative wall 1.1. End fitting limiting structures are provided at both ends near the gap 2.1, and a middle fitting limiting structure is provided between the end fitting limiting structures at both ends. The end limiting structure and the middle limiting structure of the inner connecting wall 1.2 of the plastic decorative strip 1 are respectively fitted and connected with the end fitting limiting structure and the middle fitting limiting structure.

[0043] The specific structure of the end fitting limiting structure is as follows: it includes a limiting rib 2.3 and an end cantilever hook 2.4. Both the limiting rib 2.3 and the end cantilever hook 2.4 protrude upwards. During assembly, the limiting rib 2.3 is inserted upwards into the limiting slot 1.8, and the end cantilever hook 2.4 is hooked onto the end plate 1.7, thereby limiting the two ends of the plastic decorative strip 1. This can better control the gap between the two ends of the plastic decorative strip 1 and the two ends of the door frame 2, so that the gap is controllable after assembly and meets the design requirements.

[0044] The specific structure of the central fitting limiting structure in this embodiment is as follows: it includes six limiting posts 2.6 arranged at intervals and three central cantilever hooks 2.5 arranged at intervals. The specific number of limiting posts 2.6 is six, corresponding one-to-one with the limiting waist holes 1.5. The specific number of central cantilever hooks 2.5 is three, corresponding one-to-one with the central locking platform 1.10. During assembly, the limiting posts 2.6 are inserted into the limiting waist holes 1.5, and the central cantilever hooks 2.5 are hooked onto the central locking platform 1.10, forming a limiting on the middle part of the plastic decorative strip 1.

[0045] In this embodiment, four fixing holes 1.4 are arranged at intervals on the inner connecting wall 1.2 of the plastic decorative strip 1, and four threaded connection holes 2.9 are arranged at intervals on the door frame 2. During assembly, the fixing holes 1.4 and the threaded connection holes 2.9 are aligned and connected by screws 6, thereby fixing the plastic decorative strip 1 and the door frame 2 together.

[0046] When the plastic decorative strip 1 is fixedly assembled to the door frame 2, the outer decorative wall 1.1 will fill the empty space 2.1. The upper edge of the outer decorative wall 1.1 and the surrounding edge 2.8 of the door frame 2 together form a cover plate installation space. The cover plate 4 will cover the door frame 2 and fit perfectly into the enclosed cover plate installation space, basically filling the cover plate installation space.

[0047] The fixed connection structure between the cover plate 4 and the door frame 2 is as follows: a support plane 2.7 is provided around the window 2.2 in the middle of the door frame 2. Double-sided adhesive 3 is pasted on the support plane 2.7. When the cover plate 4 is placed on the door frame 2, it will also be stuck to the double-sided adhesive 3, thereby achieving a fixed connection between the cover plate 4 and the door frame 2 through the double-sided adhesive 3.

[0048] In this embodiment, mounting holes are provided on both sides of the bottom of the door cover frame 2. The mounting holes are close to the front of the door cover frame 2. The door cover buffer pad 5 is embedded in the mounting holes. Part of the door cover buffer pad 5 protrudes outside the mounting holes and is used to form a buffer with the top of the washing machine when the door cover is closed during use.

[0049] In this embodiment, a ventilation and drainage hole 2.10 is provided in the middle of the front side of the door frame 2.

[0050] The assembly process of the washing machine door in this embodiment is as follows:

[0051] Step 1: First, assemble the plastic decorative strip 1 onto the door frame 2, such as... Figure 7 As shown:

[0052] The limiting latches 1.8 at both ends of the plastic decorative strip 1 are fastened to the limiting ribs 2.3 at both ends of the door frame 2, and then the two ends of the plastic decorative strip 1 are pressed down so that the end cantilever hooks 2.4 at both ends are hooked onto the end brackets 1.7 at both ends.

[0053] Place the limiting waist hole 1.5 of the plastic decorative strip 1 onto the limiting post 2.6 of the door frame 2, and then press the position of the middle card plate 1.10 one by one so that the middle cantilever hook 2.5 of the door frame 2 hooks onto the middle card plate 1.10.

[0054] Secure the plastic decorative strip 1 to the door frame 2 with screws 6. This completes the assembly of the plastic decorative strip 1.

[0055] Step 2: Stick sections of double-sided tape 3 onto the top of the door frame 2;

[0056] Step 3: Clean the cover plate 4, put the cover plate 4 on top of the door frame 2, so that the cover plate 4 fits and is embedded on the top of the door frame 2, then apply a certain pressure and hold for a certain time, and the cover plate 4 will be fixed to the door frame 2 with double-sided tape 3.
