Description

Technical Field

[0001] This utility model relates to the field of touch display panels, and in particular to a multi-mode touch display panel. Background Technology

[0002] Touch display panels are widely used in various household appliances, such as washing machines and refrigerators. With the development of technology, the functions of washing machines are becoming more and more diversified. Although the same model of washing machine has the same appearance, its functions are different. For example, washing machines (non-drying), washing machines (drying), and dryers. For the convenience of production, a manufacturer will use the same mold for the outer shell of the washing machine, so the size of the touch display panel used to install it is also the same. However, washing machines with different functions need to be equipped with different functional touch display panels. This requires the production of display panels with multiple functional specifications, and the corresponding control boards also need to be multiple. This will increase the manufacturer's mold opening cost and subsequent identification cost, as well as the error cost in the assembly process of workers. Utility Model Content

[0003] The purpose of this invention is to provide a multi-mode touch display panel that integrates the functions used in a washing machine onto a control board and sets multiple interfaces on the control board for connecting different functions. This allows touch display panels of washing machines of the same specifications but different functions to share the same specification control board, which facilitates production and assembly.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-mode touch display panel, including a housing, a control circuit board installed inside the housing, a light guide plate attached to the control circuit board, a color film attached to the light guide plate, and terminals and an MCU provided at the bottom of the control circuit board. All terminals are connected to the MCU, and the terminals are used to connect the power supply and the execution components of various functions of the washing machine.

[0005] Preferably, the colored diaphragm comprises two parts, one part being an operation display part and the other part being an identification part, which is printed with corresponding patterns for various functions. The patterns are used to display the program corresponding to the garment and to guide the connection of the terminals.

[0006] Preferably, the housing is provided with support blocks for supporting the control circuit board, and the support blocks are located on both sides of the housing, with no less than three on each side, and the support blocks support the lower edge of the control circuit board, with the width of the support blocks supporting the control circuit board not exceeding 5mm.

[0007] Preferably, the housing has a mounting groove, a panel is mounted in the mounting groove, the upper surface of the panel is flush with the housing, and the panel is a transparent panel.

[0008] Preferably, the portion of the housing with the mounting groove has a snap-fit ​​groove, the lower part of the panel has a mounting hook that can pass through the snap-fit ​​groove, and the housing also has a snap-fit ​​block that cooperates with the mounting hook.

[0009] Preferably, the size of the buckle groove is larger than that of the mounting hook, and the mounting hook has an elastically deformable structure. During the process of inserting the mounting hook into the buckle groove, the hook mating block abuts against the hook-shaped part of the mounting hook and causes it to deform.

[0010] The technical effects of this utility model are as follows: The functions used by the washing machine are integrated into the control board, and multiple interfaces are set on the control board for connecting different functions. In this way, the touch display panels of washing machines of the same specification but different functions can share the same specification control board. The functional specifications of the washing machine are displayed by the patterns printed on the colored film, which guides the subsequent connection of the washing machine functional components and terminals, facilitating production and assembly.

[0011] The support block design provides good support for the control circuit board without interfering with the terminal connections, and it is also easier to install compared to the structure of bolt locking.

[0012] The design of the mounting groove facilitates the installation of the panel and makes it flush with the surface of the housing, ensuring an overall aesthetic appearance. The design of the snap-fit ​​groove, mounting hook, and hook mating block ensures the stability of the panel installation while also facilitating disassembly and replacement during maintenance.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0023] like Figures 1-4 and Figure 7 As shown, this application discloses a multi-mode touch display panel, including a housing 1. A control circuit board 4 is installed inside the housing 1. A light guide plate is attached to the control circuit board 4, and a color film is attached to the light guide plate. Terminals and an MCU are provided at the lower part of the control circuit board 4. All terminals are connected to the MCU. The terminals are used to connect to the power supply and the execution components of various functions of the washing machine. The color film includes two parts, one part is an operation display part, and the other part is an identification part, which is printed with corresponding patterns for various functions. The patterns are used to display the program used for the clothes and to guide the connection of the terminals.

[0024] As washing machines offer increasingly diverse functions and accommodate different materials with various programs—such as smart drying for large items, quick drying for mite removal, quiet drum drying for wool, and online drying for rain jackets—these functions are indicated by patterns and text printed on a colored film. This guides users on proper operation and allows them to identify the washing machine's functions and select the appropriate terminals. This ensures that washing machines (or dryers) with different functions maintain a consistent appearance, requiring only one type of touch display panel and connection to the corresponding ports. This fulfills the need for multi-mode touch display and avoids incorrect wiring when multiple control circuit boards are used simultaneously. This improves production and assembly efficiency and reduces costs in this area.

[0025] in Figure 8 This document describes the specific connection details of the control circuit board terminals for a washing machine, showing the connection of some terminals.

[0026] like Figure 3 and Figure 5As shown, the housing 1 is provided with a support block 5 for supporting the control circuit board 4, and the support block 5 is located on both sides of the housing 1, with no less than three on each side. The support block 5 supports the lower edge of the control circuit board 4, and the width of the support block 5 supporting the control circuit board 4 does not exceed 5mm.

[0027] When the control circuit board 4 is placed inside the housing 1, its edges are supported by multiple support blocks 5 (similar to multi-point support). Compared with the four-sided support of the slot structure, the support contact area can be reduced, thereby reducing the possibility of interference with the control circuit board. When making terminal connections, interference can also be better avoided.

[0028] like Figure 3 , Figure 5 and Figure 6 As shown, the housing 1 has a mounting groove 6, on which a panel 2 is mounted. The upper surface of the panel 2 is flush with the housing, and the panel 2 is a transparent panel. The housing 1 has a snap-fit ​​groove 7 at the location where the mounting groove 6 is located. A mounting hook 8 that can pass through the snap-fit ​​groove 7 is provided below the panel 2. The housing 1 also has a hook engagement block 9 that cooperates with the mounting hook 8. The size of the snap-fit ​​groove 7 is larger than that of the mounting hook 8, and the mounting hook 8 has an elastically deformable structure. During the process of the mounting hook 8 being inserted into the snap-fit ​​groove 7, the hook engagement block 9 abuts against the hook-shaped part of the mounting hook and causes it to deform.

[0029] The specific installation of panel 2 is as follows: First, insert all the mounting hooks 8 of the panel into the corresponding snap-fit ​​slots 7. Then, lower the panel horizontally so that the mounting hooks 8 can fully enter the snap-fit ​​slots 7 and the panel 2 can enter the mounting groove 6. During the insertion process, the hook-shaped part of the mounting hook will always press against the hook mating block 9 and undergo elastic deformation. After the insertion is completed, the hook-shaped part of the mounting hook will exceed the hook mating block and then return to its elastic deformation, so that the hook-shaped part hooks the hook mating block 9 to complete the tight connection. When disassembly is required, simply pull the hook-shaped part of the mounting hook 8 to separate it from the hook mating block 9, and the panel and mounting hooks 8 can be taken out as a whole.
