Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to an assembly structure of an integrated front panel and knob, and a washing machine. Background Technology

[0002] In commonly used traditional washing machines in households, the front door panel and control panel are usually separate plastic panels, such as... Figure 1 As shown, during the processing and molding of the control plate 9, multiple different slot structures are formed at the part where the knob 10 is installed. These are used to engage and fix the knob 10 with various components. Because the plastic plate is relatively brittle, multiple slot structures are needed to fix the knob 10. The multiple slots engage with different components of the knob 10, so that when the knob 10 is subjected to external force, the stress will not be concentrated at a certain connection point, but will be transmitted to the plastic control plate 9 through multiple slots, thereby dispersing the stress and preventing deformation or breakage at the connection between the control plate 9 and the knob 10. However, the control plate 9 with multiple slot structures is relatively complex, which makes the assembly of the knob 10 and the control plate 9 time-consuming.

[0003] Therefore, existing technologies still need to be improved and enhanced. Utility Model Content

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] In commonly used traditional washing machines in households, the front door panel and control panel are usually separate plastic panels, such as... Figure 1 As shown, during the manufacturing process of the control plate 9, multiple different slot structures are formed at the location where the knob 10 is installed. These slots are used to engage and fix the knob 10 to various components. Because the plastic sheet is relatively brittle, multiple slot structures are needed to fix the knob 10. These slots engage with different components of the knob 10, ensuring that when the knob 10 is subjected to external forces (such as torque during rotation or impact from accidental collisions), the stress is not concentrated at a single connection point but is transmitted to the plastic control plate 9 through multiple slots. This disperses the stress and prevents deformation or breakage of the slots on the control plate. Therefore, the assembly structure of the knob 10 and control plate 9 in existing traditional washing machines is relatively complex, resulting in time-consuming assembly. This utility model provides the following embodiments to solve the above problems.

[0020] Example 1: Please see Figures 2-8 The integrated front panel and knob assembly structure includes: a metal front panel 1, on which a mounting hole 2 is provided; an L-shaped first support member 3 extends from one end of the mounting hole 2 toward the inner side of the metal front panel 1; a first section of the first support member 3 is connected to one end of the mounting hole 2; and a second section of the first support member 3 corresponds to the end face of the mounting hole 2; a knob mounting base 4, which is located inside the mounting hole 2 and detachably mounted on the second section of the first support member 3; and a knob body 5, the inner end of which is located inside the mounting hole 2 and connected to the knob mounting base 4; and the outer end of the knob body 5 extending out of the mounting hole 2.

[0021] like Figures 2-4As shown, in one embodiment of this utility model, the assembly structure of the integrated front panel and knob includes a metal front panel 1 and a knob body 5. In this embodiment, the metal front panel 1 can be a stainless steel plate or an aluminum plate, etc. Compared with the plastic control panel, the metal front panel 1 is harder and less prone to deformation or breakage. Due to the limitations of the manufacturing process, it is also difficult to process the metal front panel 1 into a complex structure with multiple different slots 701. Therefore, in this embodiment, the metal front panel 1 forms a first support member 3 for supporting the knob mounting base 4 and the knob body 5 by opening a circular mounting hole 2.

[0022] Specifically, one end of the mounting hole 2 extends inward toward the metal front plate 1 with an L-shaped first support member 3. The first support member 3 is integrally formed with the metal front plate 1 and is manufactured by sheet metal bending. The first end of the first support member 3 is connected to one end of the mounting hole 2, and the second end of the first support member 3 corresponds to the end face of the mounting hole 2. The knob mounting base 4 is located inside the mounting hole 2 and is detachably mounted on the second end of the first support member 3, and is supported and fixed by the second end of the first support member 3. The inner end (fixed end) of the knob body 5 is located inside the mounting hole 2 and connected to the knob mounting base 4, and the outer end (movable end) of the knob body 5 extends out of the mounting hole 2. When it is necessary to install the knob body 5, the knob body 5 and the knob mounting base 4 can be assembled first, and then the knob mounting base 4 can be assembled with the metal front plate 1. In this invention, the metal front plate 1 supports and fixes the knob mounting base 4 through the mounting hole 2 and the first support member 3. The knob body 5 is installed on the knob mounting base 4. In this invention, the metal front plate 1 does not need to be processed with multiple different slots 701 structures. It only needs to process an L-shaped first support member 3 extending from one end of the mounting hole 2 to support and fix the knob mounting base 4. Then, the knob body 5 can be installed on the knob mounting base 4 as a whole. The metal front plate 1 in this invention has a simple structure and is easy to process, which reduces the difficulty and cost of sheet metal processing. At the same time, it retains the advantages of the metal front plate 1 in terms of scratch resistance and aesthetics, and facilitates the quick assembly of the knob mounting base 4 and the knob body 5.

[0023] like Figure 5 and Figure 6As shown, further, the second section of the first support member 3 is parallel to the end face of the mounting hole 2, the second section of the first support member 3 is provided with a through hole 301, the back side of the knob mounting base 4 is provided with a positioning post 401, the positioning post 401 is provided with a first screw hole 402, the back side of the knob mounting base 4 abuts against the second section of the first support member 3, and the through hole 301 corresponds to the first screw hole 402 and is detachably connected by screws. Specifically, the bottom end of the positioning post 401 is provided with a first screw hole 402. The bottom end face of the positioning post 401 abuts against the second section of the first support member 3, and the first screw hole 402 corresponds to the through hole 301. The positioning post 401 and the second section of the first support member 3 can be detachably connected by a combination of screws, through hole 301, and first screw hole 402. One end of the screw passes through the through hole 301 and extends into the first screw hole 402 to be threadedly connected to the positioning post 401, and the other end abuts against the side of the second section of the first support member 3 away from the positioning post 401.

[0024] Furthermore, the second segment of the first support member 3 has a rounded edge at its end, and the length of the second segment of the first support member 3 is less than the radius of the mounting hole 2. Specifically, when assembling the knob mounting base 4 on the production line, the operator needs to reach into the inside of the metal front plate 1 and close to the second segment of the first support member 3 to tighten the screws. If the second segment of the first support member 3 has a right-angled end, the hand is easily scratched during movement or adjustment. When disassembling the mounting base during maintenance, it is necessary to touch the second segment of the first support member 3 again. The rounded edge can prevent maintenance personnel from being scratched by the end of the second segment of the first support member 3 during operation, and at the same time prevent metal debris (which is easily generated by collision at the right-angled end) from falling into the washing machine during maintenance. At the same time, there is an electrical connection structure between the fixed end of the knob body 5 and the inside of the washing machine. The length of the second segment of the first support member 3 is less than the radius of the mounting hole 2, which can form an annular reserved space inside the mounting hole 2 to avoid interference with the electrical connection structure.

[0025] In one embodiment of this utility model, the back side of the knob mounting base 4 is further provided with an arc-shaped positioning plate 403. The arc of the arc-shaped positioning plate 403 is consistent with the arc of the second end of the first support member 3, and is used to abut against the second end of the first support member 3. The arc-shaped positioning plate 403 is used to initially position the knob mounting base 4 when it is installed, so as to facilitate the subsequent assembly of the screw with the through hole 301 and the first screw hole 402.

[0026] Furthermore, the first support member 3 has three members arranged in a triangular symmetrical distribution, and the knob mounting base 4 has three positioning posts 401 on its back side. Each positioning post 401 is connected to a corresponding second segment of each of the first support members 3. When the knob mounting base 4 is subjected to lateral force, it is prone to overturning (rotating and tilting around a certain first support member 3). The triangular symmetrical distribution of the first support members 3 can significantly improve the anti-overturning ability.

[0027] like Figure 7 and Figure 8 As shown, further, one end of the mounting hole 2 extends into the inner side of the metal front plate 1 with an L-shaped second support member 7. The first section of the second support member 7 is connected to one end of the mounting hole 2, and the second section of the second support member 7 corresponds to the end face of the mounting hole 2. The distance between the second section of the second support member 7 and the mounting hole 2 is less than the distance between the second section of the first support member 3 and the mounting hole 2. The outer edge of the back side of the knob mounting base 4 abuts against the second section of the second support member 7.

[0028] Specifically, the first support member 3 is connected to the inner side of the knob mounting base 4 via the positioning post 401, which can limit the knob mounting base 4 from shifting towards the center of the mounting hole 2; while the second support member 7, by abutting against the outer edge of the back side of the knob mounting base 4, can limit the knob mounting base 4 from shifting towards the edge of the mounting hole 2. Compared with the first support member 3 alone for support and fixation, the tight abutment between the second support member 7 and the outer edge of the knob mounting base 4 can fill the radial gap and prevent the knob mounting base 4 from radially shaking under vibration.

[0029] In one embodiment of this utility model, a second support member 7 is provided between each adjacent first support member 3, and the three second support members 7 are distributed in a triangular symmetrical manner. A connecting edge 6 is provided between each adjacent first support member 3 and second support member 7. The three second support members 7 are located between adjacent first support members 3, forming a uniform distribution at 60° intervals (the first and second support members 7 are arranged alternately), which can cover the entire outer edge of the knob mounting base 4, realizing the full-range distribution of load. The connecting edge 6 can enhance the deformation resistance of adjacent first support members 3 and second support members 7, and improve structural stability.

[0030] Furthermore, a slot 701 is provided on the second section of the second support member 7, and a protrusion 404 is provided on the back side of the knob mounting base 4, which engages with the slot 701. The slot 701 is used to position the knob mounting base 4 before it is locked with screws, so as to facilitate the subsequent precise positioning and connection of the screws with the first screw hole 402.

[0031] Furthermore, the assembly structure of the integrated front panel and knob also includes a screw 8. The knob mounting base 4 has a second screw hole 405. One end of the screw 8 abuts against the back side of the knob mounting base 4, and the other end passes through the second screw hole 405 and is threadedly connected to the knob body 5. Before inserting the knob mounting base 4 into the mounting hole 2, the screw 8 can be used to assemble the knob mounting base 4 and the knob body 5. The fixed end of the knob body 5 has a screw hole for connecting with the screw 8. At the same time, the outer side of the knob mounting base 4 also has a mounting groove 406 for accommodating the fixed end of the knob body 5, and the second screw hole 405 is located in the mounting groove 406.

[0032] Example 2: This utility model embodiment also provides a washing machine, which includes an assembly structure of an integrated front panel and a knob as described in any one of Embodiment 1.

In this invention, the metal front plate 1 supports and fixes the knob mounting base 4 through the mounting hole 2 and the first support member 3. The knob body 5 is installed on the knob mounting base 4. In this invention, the metal front plate 1 does not need to be processed with multiple different slots 701 structures. It only needs to process an L-shaped first support member 3 extending from one end of the mounting hole 2 to support and fix the knob mounting base 4. Then, the knob body 5 can be installed on the knob mounting base 4 as a whole. The metal front plate 1 in this invention has a simple structure and is easy to process, which facilitates the quick assembly of the knob mounting base 4 and the knob body 5.
