Description

Technical Field

[0001] The utility model relates to the technical field of washing machine installation, in particular to a washing machine control panel with a quick installation structure. Background Art

[0002] The control panel of the washing machine is the main interface for users to interact with the washing machine. It is used to set and select washing programs, adjust washing time and water level, etc. Some high-end washing machines also have smart function keys, such as AI artificial intelligence washing and stain removal technology. These functions need to be accessed through mobile phone APP or Wi-Fi and other network access. These smart function keys can automatically adjust parameters such as washing programs and water levels according to factors such as the material of the clothes and the degree of stains, making the washing effect even better.

[0003] At present, the conventional installation method of the washing machine control panel and its external mounting panel mainly relies on a hard card block structure to fix and limit the PCB board in the control panel. During the traditional installation and clamping process, it is necessary to manually pry the board connected by the hard card blocks on both sides, causing the hard card blocks to deform. At the same time, a certain pressing force must be applied to ensure that the PCB board is tightly combined with the mounting panel. However, this hard buckle structure has some disadvantages. Specifically, during the clamping process, when the operator lacks skills or presses hard, the PCB board often bears excessive pressure, which may cause it to break or even be directly damaged, reducing the overall protection effect of the PCB board in the control panel. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a washing machine control panel with a quick installation structure to solve the problem that the PCB board is subjected to excessive pressure during the locking process, resulting in damage or circulation of the PCB board, thereby reducing the technical problem of the protection of the PCB board in the control panel.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a washing machine control panel with a quick installation structure, comprising an installation panel, a digital display screen, a knob and a PCB board, an upper limit plate and a lower limit plate are respectively arranged on the upper and lower sides of the back of the installation panel, a second latching tooth is arranged on the inner side of the upper limit plate, a first latching tooth is arranged on the inner side of the lower limit plate, a movable groove is opened on the outer side of the first latching tooth, a pressing mechanism is arranged on one side of the lower limit plate, the pressing mechanism comprises a slide rail, and the inner side of the slide rail is slidably connected with the pressing plate.

[0006] By adopting the above technical solution, the first latching tooth is more likely to deform when pressed by the PCB board. This deformation enables the PCB board to engage with the first latching tooth and the second latching tooth more smoothly, thereby improving the convenience of the installation process.

[0007] Furthermore, the upper limit plate, the lower limit plate and the mounting panel are an integrated structure, and the cross section is a "U"-shaped structure.

[0008] By adopting the above technical solution, the overall structural strength and stability are enhanced, making it difficult for the control panel to deform or loosen during installation and use, thereby ensuring the reliability and durability of the control panel.

[0009] Furthermore, the first latching tooth and the second latching tooth are both wedge-shaped structures, and the PCB board is engaged with the upper limit plate and the lower limit plate through the first latching tooth and the second latching tooth.

[0010] By adopting the above technical solution and the wedge-shaped structure, the PCB board can more easily slide into the gap between the locking teeth when engaging with the upper limit plate and the lower limit plate, thereby improving the installation efficiency.

[0011] Furthermore, the pressure plate is in contact with the first latching tooth, and the pressure plate is used to limit the position of the first latching tooth. A friction block is provided on one side of the pressure plate to provide a supporting point for the operator to act on the pressure plate.

[0012] By adopting the above technical solution, the position of the first locking tooth can be effectively limited to prevent it from unnecessary deformation or movement due to stress or other factors, thereby enhancing the fixing effect of the first locking tooth on the PCB board and improving the structural stability of the control panel.

[0013] Furthermore, the movable groove is used to provide a stress bending space for the first latching tooth, and the pressure plate and the lower limit plate are connected and fixed by reinforcing bolts.

[0014] By adopting the above technical solution, the movable groove provides a stress bending space for the first tooth, which means that when the PCB board applies pressure to the first tooth, the first tooth can be deformed within the range of the movable groove, thereby better adapting to and fixing the PCB board and reducing stress concentration during the installation process.

[0015] Furthermore, a placement groove is provided on the surface of the pressure plate, and a plurality of wire grooves are provided on the surface of the lower limit plate, and the placement grooves are opposite to the wire grooves.

[0016] By adopting the above technical solution, the neatness of the layout of the data cables inside the control panel is ensured. When the data cables connected to the PCB board pass through the lower limit plate and the pressure plate, they can be conveniently placed in the placement groove, avoiding the problem of disordered data cables.

[0017] Furthermore, a winding mechanism is provided inside the placement slot, and the winding mechanism is used to wind up the data line connected to the PCB board.

[0018] By adopting the above technical solution, the winding mechanism provides a special winding space for the data cable connected to the PCB board, so that the excess data cable can be neatly rolled up and fixed, avoiding the problem of the data cable being scattered inside the control panel.

[0019] Furthermore, the winding mechanism includes two mounting plates, and the mounting plates are provided with slots.

[0020] By adopting the above technical solution, a stable support point is provided for the winding of the data cable, and the mounting plate can be firmly fixed in the placement groove to ensure that the data cable will not slip or loosen during the winding process.

[0021] Furthermore, the surface of the mounting panel is provided with mounting grooves and through holes for mounting a digital display screen and a knob.

[0022] By adopting the above technical solution, the mounting groove provides a precise embedding position for the digital display screen, so that the digital display screen can be firmly installed on the control panel without shaking or falling off, ensuring that the user can clearly read the information on the display screen during use.

[0023] Furthermore, the installation panel is fixedly connected to the external washing machine shell through the installation ears, and a plurality of the first latch teeth and the second latch teeth are provided, and the plurality of the first latch teeth and the second latch teeth are linearly arranged at equal intervals along the length line of the installation panel.

[0024] By adopting the above technical solution, the control panel can be stably and reliably fixed on the outer shell of the washing machine and is not easy to loosen or fall off, thereby ensuring the normal use and long-term stability of the control panel.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses the movable groove and the setting of the pressing mechanism. When the PCB board is installed, the limiting property of the first clamping tooth can be improved, and the size data of the movable groove can be increased, so that the first clamping tooth is more likely to deform when pressed by the PCB board. This feature helps to simplify the installation process, because the operator no longer needs to exert excessive force to clamp the PCB board into the hard clamping tooth. At the same time, it also prevents the damage to the PCB board caused by the traditional hard clamping tooth during the installation process. Since the first clamping tooth can more flexibly adapt to the shape and size of the PCB board, the risk of damage caused by stress concentration during the installation process is reduced;

[0027] 2. The utility model provides a reeling mechanism, so that the data line connected to the PCB board can smoothly pass through the lower limit plate and the pressure plate through the line groove and the placement groove, ensuring the orderly wiring of the data line inside the control panel and avoiding the confusion and entanglement that may occur in the traditional wiring method. At the same time, by utilizing the mounting plate and the card slot, the excess data line can be effectively reeled up, which not only further improves the neatness of the internal line and eliminates the clutter, but also helps to improve the reliability and maintenance convenience of the control panel. The neat line layout reduces the probability of failure and is also convenient for subsequent maintenance and inspection. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1:

[0036] A washing machine control panel with a quick installation structure, such as Figure 1-Figure 4As shown, it includes an installation panel 1, a digital display screen 201, a knob 202 and a PCB board 203. An upper limit plate 302 and a lower limit plate 301 are respectively arranged on the upper and lower sides of the back of the installation panel 1. A second latch 403 is arranged on the inner side of the upper limit plate 302, and a first latch 401 is arranged on the inner side of the lower limit plate 301. A movable groove 402 is opened on the outer side of the first latch 401. A pressing mechanism 6 is arranged on one side of the lower limit plate 301. The pressing mechanism 6 includes a slide rail 601. The inner side of the slide rail 601 is slidably connected with a pressing plate 602, the first latch tooth 401 is more likely to be deformed when pressed by the PCB board 203. This deformation enables the PCB board 203 to be more smoothly engaged with the first latch tooth 401 and the second latch tooth 403, thereby improving the convenience of the installation process. At the same time, since the first latch tooth 401 can be more easily deformed, the damage that the traditional hard latch tooth may cause to the PCB board 203 during the installation process is reduced, which not only protects the integrity of the PCB board, but also improves the reliability and durability of the control panel.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The upper limit plate 302, the lower limit plate 301 and the installation panel 1 are an integrated structure, and the cross section is a "U"-shaped structure, which enhances the overall structural strength and stability, making it difficult for the control panel to deform or loosen during installation and use, thereby ensuring the reliability and durability of the control panel. At the same time, the cross section of the structure is a "U"-shaped, which helps to better limit and fix the PCB board 203. The PCB board 203 is tightly clamped between the upper limit plate 302 and the lower limit plate 301, effectively preventing the PCB board 203 from moving or shaking after installation.

[0038] See also Figure 3 , Figure 4 The first latch tooth 401 and the second latch tooth 403 are both wedge-shaped structures. The PCB board 203 is engaged with the upper limit plate 302 and the lower limit plate 301 through the first latch tooth 401 and the second latch tooth 403. The wedge-shaped structure enables the PCB board 203 to slide more easily into the gap between the latch teeth when engaging with the upper limit plate 302 and the lower limit plate 301, thereby improving the installation efficiency. At the same time, the wedge-shaped latch tooth structure can provide stable support and limiting effects after the PCB board 203 is engaged in place. This structure can effectively prevent the PCB board 203 from loosening or falling off after installation, thereby ensuring the stability and reliability of the control panel.

[0039] See also Figure 3 , Figure 4The pressing plate 602 is in contact with the first latch tooth 401, and the pressing plate 602 is used to limit the position of the first latch tooth 401. A friction block 10 is provided on one side of the pressing plate 602 to provide an operating support point for the operator to apply the pressing plate 602, which can effectively limit the position of the first latch tooth 401 and prevent it from being deformed or moved unnecessarily due to stress or other factors, thereby enhancing the fixing effect of the first latch tooth 401 on the PCB board 203 and improving the structural stability of the control panel. At the same time, a friction block 10 is provided on one side of the pressing plate 602 to provide an operator with a clear and stable supporting point, which enables the operator to apply force more conveniently when installing or removing the control panel, thereby improving the efficiency and comfort of the operation. The existence of the friction block 10 also increases the friction between the operator's hand and the pressing plate 602, which helps to prevent slippage or misoperation during operation.

[0040] See also Figure 3 , Figure 4 The movable groove 402 is used to provide stress bending space for the first clamping tooth 401. The pressure plate 602 is connected and fixed to the lower limit plate 301 by the reinforcing bolt 9. The movable groove 402 provides stress bending space for the first clamping tooth 401, which means that when the PCB board 203 applies pressure to the first clamping tooth 401, the first clamping tooth 401 can be deformed within the range of the movable groove 402, so as to better adapt to and fix the PCB board 203, reduce stress concentration during installation, and at the same time, enhance the overall structural strength of the control panel. The connection method of the reinforcing bolt 9 ensures the stability of the pressure plate 602 when limiting the position of the first clamping tooth 401, effectively prevents the control panel from loosening or deformation during use, and improves the reliability and durability of the product.

[0041] See also Figure 3 , Figure 4 A placement groove 603 is provided on the surface of the pressure plate 602, and a plurality of wire grooves 7 are provided on the surface of the lower limit plate 301. The placement groove 603 is opposite to the wire groove 7, ensuring the neatness of the layout of the data line inside the control panel. When the data line connected to the PCB board 203 passes through the lower limit plate 301 and the pressure plate 602, it can be conveniently placed in the placement groove 603, avoiding the problem of disordered data lines. At the same time, the plurality of wire grooves 7 on the surface of the lower limit plate 301 are opposite to the placement groove 603, so that the data line can pass through the wire groove 7 more smoothly during the penetration process, further improving the regularity of the data line layout.

[0042] Embodiment 2:

[0043] See also Figure 4A winding mechanism 8 is provided on the inner side of the placement groove 603. The winding mechanism 8 is used to wind up the data cable connected to the PCB board 203. The winding mechanism 8 provides a special winding space for the data cable connected to the PCB board 203, so that the excess data cable can be neatly rolled up and fixed, avoiding the problem of the data cable being scattered inside the control panel. At the same time, the winding processing of the excess data cable by the winding mechanism 8 not only improves the neatness of the line inside the control panel, but also helps to reduce the entanglement, knotting or wear of the data cable during use, thereby protecting the integrity and service life of the data cable.

[0044] See also Figure 4 The winding mechanism 8 includes two mounting pieces 801, and a card slot 802 is provided on the mounting piece 801, which provides a stable support point for the winding of the data cable. The mounting piece 801 can be firmly fixed in the placement slot 603 to ensure that the data cable will not slip or loosen during the winding process. At the same time, the card slot 802 provided on the mounting piece 801 makes the winding of the data cable more orderly and reliable, and the excess data cable can be neatly inserted into the card slot 802, avoiding the possible scattering or falling off of the data cable after winding, which not only improves the convenience of data cable management, but also further improves the cleanliness inside the control panel.

[0045] See also Figure 1 , Figure 2 The surface of the mounting panel 1 is provided with a mounting groove 205 and a through hole 204 for mounting the digital display screen 201 and the knob 202. The mounting groove 205 provides a precise embedding position for the digital display screen 201, so that the digital display screen 201 can be firmly mounted on the control panel without shaking or falling off, ensuring that the user can clearly read the information on the display screen during use. At the same time, the setting of the through hole 204 facilitates the installation of the knob 202. The knob 202 can be inserted from one side of the mounting panel 1 through the through hole 204 and then fixed at the corresponding position on the other side, which not only simplifies the installation process of the knob 202, but also improves the stability and reliability of the knob 202 after installation.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The mounting panel 1 is fixedly connected to the external washing machine shell through the mounting ear 5. A plurality of first latch teeth 401 and second latch teeth 403 are provided. The plurality of first latch teeth 401 and second latch teeth 403 are arranged equidistantly linearly along the length line of the mounting panel 1, so that the control panel can be stably and reliably fixed on the washing machine shell and is not easy to loosen or fall off, thereby ensuring the normal use and long-term stability of the control panel. At the same time, a plurality of first latch teeth 401 and second latch teeth 403 are provided, so that the PCB board 203 can be uniformly and stably engaged at multiple positions, further enhancing the connection stability between the PCB board 203 and the control panel.

[0047] The implementation principle of the utility model is as follows: first, the digital display screen 201 is positioned opposite to the mounting slot 205, and then the second latching teeth 403 are used to perform a preliminary latching operation on the PCB board 203. Then, the other side of the PCB board 203 is pressed. Due to the setting of the movable slot 402, it is easier for the first latching teeth 401 to deform when the PCB board 203 presses, thereby lifting the PCB board 203 and the first latching teeth 401 and the second latching teeth 403. The convenience of the combination can prevent the hard teeth from causing damage to the PCB board 203 in the traditional process. Then, the inner pressing plate 602 is slid by the slide rail 601 until the pressing plate 602 is used to press and limit the first tooth 401 to prevent the stress deformation of the first tooth 401 and improve the installation structure firmness of the PCB board 203. After that, the pressing plate 602 is fixedly connected to the lower limit plate 301 by the reinforcing bolts 9 to complete the installation operation of the control panel.

[0048] The data line connected to the PCB board 203 can pass through the lower limit plate 301 and the pressure plate 602 through the wire groove 7 and the placement groove 603. Then, the excess data line is rolled up using the installation piece 801 and the card slot 802 to avoid the clutter of excess data lines and improve the neatness of the internal circuit.

[0049] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
