Description

Technical Field

[0001] This utility model relates to the field of washing machine parts manufacturing technology, specifically to a paint-free control board for washing machines. Background Technology

[0002] The washing machine control board is the board that integrates the core electronic control components of the washing machine. It is usually installed on the washing machine rack. The washing machine control board has buttons and functions such as program selection, parameter adjustment, status display and safety protection. Users can operate it through buttons or touch interface. Some high-end control boards also support intelligent upgrades such as Internet of Things connection and intelligent identification of clothing material to automatically match the program, so as to achieve an efficient, energy-saving and convenient washing experience.

[0003] The control panel and rack of a washing machine are usually assembled by first snapping them together with clips and then tightening them with screws. The clips on the control panel are usually molded as one piece and protrude from the control panel. This structure makes it a weak point in terms of mechanics. The protruding clips are easily subjected to impacts such as collisions and squeezing during transportation and transfer. When stacked and pressed, they act as support points to bear concentrated loads. Moreover, the plastic clips are prone to stress concentration under long-term or sudden stress, which can easily lead to breakage. Utility Model Content

[0004] The purpose of this invention is to provide a snap-lockable and retractable washing machine control board, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A paint-free control board for a washing machine includes a main body. Several mounting slots are arranged sequentially along the edge on the back of the main body. Each mounting slot is provided with an adjustment mechanism. Each adjustment mechanism is equipped with a snap-on body. The snap-on body can be rotated and adjusted within the mounting slot through the adjustment mechanism to extend and retract. The adjustment mechanism includes a threaded rod. Insertion holes are provided on the inner walls of both sides of the mounting slot. The two ends of the threaded rod are respectively inserted into the corresponding insertion holes. The snap-on body is threadedly fitted onto the threaded rod through the threaded hole on it.

[0007] Therefore, the buckle body can be rotated and adjusted within the mounting slot through the adjustment mechanism to extend and retract. During transportation and transfer, storing the buckle body within the mounting slot can effectively prevent the extended buckle body from being impacted by external forces or subjected to heavy pressure from stacking, reducing the risk of breakage due to stress concentration. During assembly, adjusting the buckle body to the extended position facilitates its engagement with the faceplate buckle slot, improving the reliability and ease of assembly of the buckle body.

[0008] Furthermore, first nuts are screwed onto the threaded rod on both sides of the buckle body, with each first nut engaging with the buckle body.

[0009] Furthermore, a second nut is screwed onto the threaded rod near its two ends, respectively, with matching threads.

[0010] Furthermore, both ends of the threaded rod are fitted with insertion parts that are limited and slidably mounted. The insertion parts can be fitted into the insertion holes, and the cross-section of the insertion parts is rectangular.

[0011] Furthermore, the motherboard body has integrally formed mounting feet on both sides, and each mounting foot has a mounting hole.

[0012] Furthermore, the front of the motherboard has a button area and an indicator light area, while the back of the motherboard near the button area has a ribbed assembly integrally formed.

[0013] Furthermore, when the two insert parts move close to each other to their limit positions, the total length of the threaded rod and the two insert parts is less than the total length of the mounting groove and the two insertion holes.

[0014] Furthermore, the motherboard body is made of ABS material.

[0015] The ABS material, calculated by weight, includes: 100 parts ABS resin, 0.2 parts antioxidant 1076, 0.3 parts antioxidant 168, 0.3 parts lubricant, 1 part aluminum powder, and 0.1 parts colorant.

[0016] The specific steps for fabricating the main body using ABS material are as follows:

[0017] S1. Mix ABS resin, antioxidant 1076, antioxidant 168, lubricant, aluminum powder, and color powder at 500 rpm for 20 minutes to obtain a mixture;

[0018] S2. The above mixture is added to a twin-screw extruder and melt-extruded and granulated to obtain the above ABS material;

[0019] The temperatures of each section of the twin-screw extruder are 170-180℃, 180-190℃, 190-200℃, 200-210℃, and 210-220℃, respectively, and the screw speed is 450 rpm.

[0020] S3. The above-mentioned PP composite material is injection molded into a main body using an injection molding machine.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0022] The buckle body can be rotated and adjusted within the mounting slot via an adjustment mechanism to extend and retract. During transportation and transfer, storing the buckle body within the mounting slot can effectively prevent the extended buckle body from being impacted by external forces or subjected to heavy pressure from stacking, reducing the risk of breakage due to stress concentration. During assembly, adjusting the buckle body to the extended position facilitates its engagement with the faceplate buckle slot, improving the reliability and ease of assembly of the buckle body.

[0023] The first nut on both sides of the snap fastener body on the threaded rod abuts against the snap fastener body. After the snap fastener body is adjusted to the extended state and the first nut is tightened, the snap fastener body can be limited to prevent it from deflecting due to pressure when the snap fastener body is pressed into the face frame snap slot when the main body is pressed. This ensures that the snap fastener body can be accurately and stably snapped into the face frame snap slot, thus improving the reliability of the connection between the snap fastener body and the face frame.

[0024] The insertion section of the sliding fitting at both ends of the threaded rod has a rectangular cross-section, which matches the insertion hole. After insertion, it can play a positioning role, preventing the threaded rod from rotating when the buckle body is turned. In addition, the second nut on the threaded rod near both ends abuts against the insertion section, which can lock the insertion section and prevent it from retracting and causing the adjustment mechanism to fail. This ensures the stability of the adjustment mechanism installation and thus ensures the stable realization of the buckle body's adjustment function.

[0025] Mounting holes are provided on the mounting feet on both sides of the mainboard. During assembly, screws are inserted into the mounting holes and tightened into the screw holes of the front panel to secure the mainboard to the front panel. Combined with the snap-fit ​​mechanism between the snap-fit ​​body and the front panel, a double fixing structure is formed, which enhances the firmness of the connection between the mainboard and the front panel. The ribs on the back of the mainboard near the button area can reinforce the button area, reduce excessive deformation caused by long-term button pressure, and improve the structural strength and service life of the mainboard.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to 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 embodiments of this utility model.

[0036] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0037] Please see Figures 1-7This utility model provides a paint-free control board for a washing machine, including a main board body 1. Several mounting slots 2 are arranged sequentially along the edge on the back of the main board body 1. Each mounting slot 2 is provided with an adjustment mechanism 4, and a buckle body 3 is installed on each adjustment mechanism 4. The buckle body 3 can be rotated and adjusted within the mounting slot 2 through the adjustment mechanism 4 to achieve extension and retraction. During transportation and transfer, the buckle body 3 is rotated and adjusted into the mounting slot 2 for storage to prevent the buckle body 3 from being squeezed or broken due to extension or collision. When the main board body 1 is assembled onto the front panel, the buckle body 3 is rotated and adjusted to extend, so that it can be easily engaged with the buckle slot on the front panel for fastening.

[0038] Among them, such as Figures 4-6 As shown, the adjustment mechanism 4 includes a threaded rod 41. The inner walls on both sides of the mounting groove 2 are provided with insertion holes 401. The two ends of the threaded rod 41 are respectively inserted into the corresponding insertion holes 401. The buckle body 3 is threadedly fitted onto the threaded rod 41 through the threaded hole 31. Under the threaded engagement between the threaded hole 31 and the threaded rod 41, the buckle body 3 can be rotated around the threaded rod 41, thereby facilitating the retraction and extension adjustment of the buckle body 3.

[0039] Specifically, the threaded rod 41 has first nuts 42 threadedly fitted on both sides of the buckle body 3. Both first nuts 42 are in contact with the buckle body 3. When the buckle body 3 is screwed and adjusted to the extended state, the buckle body 3 is limited by tightening both first nuts 42 toward one side of the buckle body 3 until the two first nuts 42 are in contact with the sides of the buckle body 3. This prevents the buckle body 3 from deflecting due to pressure when the main board 1 is pressed to snap into the buckle slot on the faceplate, ensuring that the buckle body 3 can be snapped into the buckle slot smoothly.

[0040] In addition, both ends of the threaded rod 41 are fitted with insertion parts 411 that are limited to slide. The insertion parts 411 can only slide and adjust along the length of the threaded rod 41 and cannot rotate relative to the threaded rod 41. The installation of the threaded rod 41 is completed by matching and inserting the two insertion parts 411 into the insertion holes 401 on both sides.

[0041] The insert part 411 has a rectangular cross-section, and the insertion hole 401 has a rectangular cross-section that matches the insert part 411. After the insert part 411 is inserted into the insertion hole 401, it plays a positioning role and prevents the insert part 411 and the threaded rod 41 from rotating as a whole when the buckle body 3 is turned.

[0042] Furthermore, when the two insert parts 411 move close to each other to their limit positions, the total length of the threaded rod 41 and the two insert parts 411 is less than the total length of the mounting groove 2 and the two insertion holes 401, ensuring that the two insert parts 411 can be smoothly inserted into the insertion holes 401 on the corresponding side.

[0043] like Figure 5 As shown, a second nut 43 is screwed onto the threaded rod 41 near its two ends. The two inserts 411 are inserted into the insertion holes 401 respectively. The second nuts 43 on both sides are turned and adjusted to the same side of the insert 411. The second nuts 43 eventually come into contact with the insert 411, which can lock the insert 411 and prevent the insert 411 from retracting and causing the threaded rod 41 to fail to install.

[0044] Both the first nut 42 and the second nut 43 are hexagonal nuts.

[0045] like Figure 3 As shown, the motherboard body 1 has integrally formed mounting feet 13 on both sides, and mounting feet 13 are provided with mounting holes 14. After the motherboard body 1 is assembled on the front panel, the fastening screws are inserted into the mounting holes 14 and tightened into the screw holes on the front panel to achieve the fastening of the motherboard body 1 and the front panel, ensuring the assembly is firm.

[0046] like Figure 1 As shown, the front of the motherboard 1 has a button area 11 and an indicator light area 12. Pressing the corresponding button area 11 allows selection of the corresponding program, and the corresponding indicator light will illuminate to provide an indication. Additionally, as... Figure 2 As shown, a rib group 15 is integrally formed on the back of the motherboard body 1 near the button area 11, which can reinforce the button area and prevent the buttons from being excessively deformed due to long-term pressure.

[0047] The motherboard body is made of ABS material, which includes the following components by weight: 100 parts ABS resin, 0.2 parts antioxidant 1076, 0.3 parts antioxidant 168, 0.3 parts lubricant, 1 part aluminum powder, and 0.1 parts color powder.

[0048] The specific steps for preparing samples using ABS material are as follows:

[0049] S1. Mix ABS resin (LG Chem 181), antioxidant 1076, antioxidant 168, lubricant (EBS), aluminum powder, and colorant (BASF) at 500 rpm for 20 minutes to obtain a mixture;

[0050] S2. The above mixture is added to a twin-screw extruder and melt-extruded and granulated to obtain the above ABS material;

[0051] The temperatures of each section of the twin-screw extruder are 170-180℃, 210-220℃, 210-220℃, 200-210℃, and the screw speed is 450 rpm.

[0052] S3. The above ABS material is injection molded into a main body sample using an injection molding machine. The main body sample has a tensile strength of about 40 MPa, a flexural strength of 65 MPa, and a flexural modulus of about 2240 MPa.

[0053] The main body 1 made of the above-mentioned ABS material has a strong metallic texture and high gloss, effectively replacing painting and significantly reducing manufacturing costs.

[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
