The following embodiments are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0042] In the related art, traditional washing machines use mechanical buttons or contact touch methods to perform function operations on the washing machines. Since direct contact with the control panel or buttons of the washing machine is required, if the user carries a virus, direct contact will cause virus residue and spread, especially when using shared washing machines, there are risks.
[0043] Reference Figures 1 - 5 As shown, an embodiment of the present application provides a touch control device 10 and a laundry treatment device to solve the problems that existing laundry treatment devices are prone to infection and have low usage safety. The following will be described in conjunction with the accompanying drawings.
[0044] According to an embodiment of the present application, reference Figure 1 and Figure 2 As shown, the touch control device 10 includes a substrate 100, a display panel 200, and a main control board 300 that are sequentially stacked. The display panel 200 is provided with an electrode array and a collector 210 connected to the electrode array. The electrode array is adapted to generate a capacitance change when the distance between the triggering body and the display panel 200 is less than a preset sensing distance. The collector 210 is adapted to collect the electrical signal generated based on the capacitance change; the main control board 300 is electrically connected to the collector 210 and is used to receive the electrical signal and generate a corresponding operation instruction.
[0045] It can be understood that in this embodiment, the substrate 100 is located on the side of the display panel 200 close to the user and is used to protect the display panel 200. The touch control device 10 realizes non-contact touch interaction by integrating an electrode array and a collector 210 on the display panel 200.
[0046] One end of the electrode array is grounded, and the other end is connected to a driving circuit to form a capacitance loop. When the user's finger or other triggering body (such as a stylus) approaches the display panel 200 within the preset sensing distance, the capacitance in the electrode array will change, thereby generating an electrical signal. This electrical signal can be captured by the collector 210 and sent to the main control board 300, allowing the user to operate without directly touching the screen. This non-contact interaction method greatly reduces the risk of cross-infection. In addition, the user does not need to worry about hand cleaning problems, nor does he need to worry about fingerprint residue or screen wear caused by long-term touching of the screen.
[0047] As the core control unit of the system, the main control board 300 can quickly receive the electrical signal transmitted by the collector 210, and based on the electrical signal, identify the function icon corresponding to the user's intention. Subsequently, the main control board 300 can generate a corresponding operation instruction to achieve the function desired by the user, realizing a fast conversion from the user's intention to the system response, and improving the fluency and satisfaction of the user experience.
[0048] According to an embodiment of the present application, reference Figure 2As shown, the electrode array includes a first electrode array 220 and a second electrode array 230. The first electrode array 220 extends along the first direction and is arranged along the second direction, and the second electrode array 230 extends along the second direction and is arranged along the first direction.
[0049] Optionally, the first electrode array 220 extends along a first direction (e.g., horizontal direction), and the first electrode array 220 is arranged along a second direction (e.g., vertical direction) to form a series of parallel electrode lines; the second electrode array 230 extends along the second direction (e.g., vertical direction), and the second electrode array 230 is arranged along the first direction (e.g., horizontal direction), so that the first electrode array 220 and the second electrode array 230 intersect at a plurality of intersection points 201, and a capacitor will be formed at the intersection of the first electrode array 220 and the second electrode array 230, that is, the first electrode array 220 and the second electrode array 230 respectively constitute two levels of electrodes. When the triggering body (such as a finger) approaches the display panel 200, it will form a capacitive coupling between the first electrode array 220 and the second electrode array 230. The change in this capacitance will be detected by the collector 210 connected to the electrode array. Since the first electrode array 220 and the second electrode array 230 are arranged in an intersecting manner, the exact position of the triggering body can be determined by detecting the electrical signal generated by the capacitance change on different electrode lines.
[0050] It can be understood that the first direction and the second direction may also be other directions, that is, the angle between the first direction and the second direction may be other values besides a right angle.
[0051] Specifically, when the triggering body approaches a certain intersection point 201, it will affect the capacitance on multiple electrode lines around the point and generate corresponding electrical signals, and different electrical signals correspond to different position coordinates of the triggering body.
[0052] According to one embodiment of the present application, referring to Figure 2 As shown, the first direction is perpendicular to the second direction.
[0053] Since the first electrode array 220 and the second electrode array 230 extend and are arranged in two perpendicular directions respectively, they can form a two-dimensional grid structure. When the main body is triggered to touch in the air, the collector 210 (touch IC) can collect the electrical signals generated by the capacitance changes in the horizontal direction (first direction) and the vertical direction (second direction), thereby accurately determining the position of the touch point. This orthogonal arrangement ensures the accuracy and reliability of positioning.
[0054] The orthogonally arranged electrode design not only supports single-point touch but also can efficiently handle multi-point touch situations. Since each electrode can independently detect capacitance changes, multiple touch points can be tracked simultaneously, and their positions on the two-dimensional plane can be determined separately.
[0055] In a specific application, parameters such as the spacing, density, and width of the first electrode array 220 and the second electrode array 230 can be adjusted as needed to optimize the touch performance.
[0056] According to an embodiment of the present application, the first electrode array 220 is configured to sequentially send signals, and the second electrode array 230 is configured to receive signals simultaneously; or, the second electrode array 230 is configured to sequentially send signals, and the first electrode array 220 is configured to receive signals simultaneously.
[0057] It can be understood that in this embodiment, by configuring one of the first electrode array 220 and the second electrode array 230 to sequentially send signals and the other to receive signals simultaneously, the touch detection efficiency can be significantly improved by sequentially sending signals and receiving simultaneously. Since the capacitance changes in each direction can be measured separately, high-precision touch positioning can be achieved, and receiving signals from multiple electrodes simultaneously helps to suppress interference and improve the detection accuracy.
[0058] In an alternative embodiment, the first electrode array 220 is configured to sequentially send signals, and the second electrode array 230 simultaneously receives these signals. When a certain first electrode sends a signal, it forms a capacitance coupling with all the second electrodes. At this time, if a touch event occurs, the second electrodes near the touch point will detect a capacitance change. After the capacitance changes, corresponding electrical signals will be generated, and different capacitance changes at different positions will generate different electrical signals, and the collector 210 can collect these electrical signals.
[0059] In another alternative embodiment, the second electrode array 230 is configured to sequentially send signals, and the first electrode array 220 simultaneously receives these signals. Similarly, when a certain second electrode sends a signal, it forms a capacitance coupling with all the first electrodes. The first electrodes near the touch point will detect a capacitance change, thereby generating corresponding electrical signals, and the collector 210 can collect these electrical signals and send them to the main control board 300.
[0060] Which specific method to adopt can be selected and optimized according to the specific application scenario and requirements, and this embodiment does not make specific limitations on this.
[0061] According to an embodiment of the present application, refer to Figure 2 and Figure 3As shown, the projections of the first electrode array 220 and the second electrode array 230 on the display panel 200 intersect at a plurality of intersection points 201. The collector 210 is configured to scan the capacitance values of each intersection point 201 to determine the two-dimensional planar capacitance distribution of the display panel 200 and collect the electrical signals generated based on the changes in the two-dimensional planar capacitance distribution.
[0062] In this embodiment, the collector 210 can be a touch integrated circuit, that is, a touch IC. The collector 210 can scan the capacitance values of these intersection points 201. When there is no touch, the capacitance value of each intersection point 201 will remain at a stable reference level, which represents the initial capacitance distribution of the display panel 200. When a triggering object (such as a finger, a stylus, etc.) approaches or touches the display panel 200, it will change the electric field distribution in some areas of the display panel 200, resulting in changes in the capacitance values of the intersection points 201 near these areas and generating corresponding electrical signals. By periodically scanning the capacitance values of each intersection point 201, the collector 210 can capture this change in real time and construct a dynamic two-dimensional planar capacitance distribution. Based on the changes in this two-dimensional planar capacitance distribution, the collector 210 collects the corresponding electrical signals and transmits them to the main control board 300. The main control board 300 generates corresponding operation instructions based on the collected electrical signals, activates the corresponding functions, and realizes the air-touch operation.
[0063] In the related art, a layer of indium tin oxide semiconductor transparent conductive film (Indium Tin Oxides, ITO) is usually provided on the surface of the touch device 10. Due to each touch press, the upper plastic (usually PET) and ITO will deform. And the ITO material is brittle and is easily damaged when the ITO deforms. Once the ITO layer breaks, the conductivity uniformity will be destroyed, affecting the normal use of the touch device 10.
[0064] According to an embodiment of the present application, the substrate 100 is ITO glass. Since the glass material does not absorb water and has a coefficient of expansion close to that of ITO, it will not cause ITO damage due to deformation during temperature changes, effectively reducing the failure rate of the display screen of the touch device 10.
[0065] According to an embodiment of the present application, refer to Figure 1 As shown, the main control board 300 is provided with a connector 310. The main control board 300 is adapted to be connected to the functional module through the connector 310 and activate the corresponding functional module based on the operation instruction. The main control board 300 generates corresponding operation instructions based on the electrical signal and sends the operation instructions to the corresponding functional module through the connector 310 to activate the corresponding function.
[0066] According to an embodiment of the present application, refer to Figure 1As shown, the connector 310 is also connected to the collector 210, and the connector 310 and the collector 210 are located on the same side of the touch device 10.
[0067] In this embodiment, the connector 310 serves as a physical interface, which not only connects the main control board 300 and the functional module, but also plays the role of connecting the main control board 300 and the collector 210. Through the connector 310, the collector 210 can accurately transmit the detected data such as electrical signals to the main control board 300.
[0068] Furthermore, the connector 310 and the collector 210 are arranged on the same side, making the wiring more intuitive and convenient. The wiring path can be more easily planned, reducing the cases of crossing and winding, improving the wiring efficiency, and also reducing the possibility of errors during the wiring process. The same-side layout also helps to achieve the structural compactness of the touch device 10 and is more easily integrated into other devices or systems.
[0069] According to an embodiment of the present application, referring to Figure 1 As shown, a polarizer 400 is provided on the side of the substrate 100 facing the display panel 200 to improve the display effect and ensure that parameters such as the quality, brightness, and contrast of the displayed image meet the requirements. Optionally, the polarizer 400 can be attached to the surface of the ITO glass, that is, the substrate 100, the polarizer 400, the display panel 200, and the main control board 300 are stacked in sequence.
[0070] In an alternative embodiment, referring to Figure 4 As shown, the operation process of the touch device 10 is as follows: The user operates the corresponding program button on the display panel 200 in the air, the electrode array senses the corresponding changed capacitance value, and the collector 210 (touch IC) scans and detects the capacitances of the first electrode array 220 and the second electrode array 230 in the horizontal and vertical directions respectively, and determines the horizontal and vertical coordinates corresponding to the touch object according to the change in capacitance before and after the touch. The display panel 200 transmits the collected analog signal to the main control board 300, and the main control board 300 can compare it with the set program corresponding value and activate the corresponding function.
[0071] An embodiment of the second aspect of the present application provides a laundry treatment device, and the laundry treatment device includes the touch device 10 of any one of the above.
[0072] Optionally, referring to Figure 5 As shown, a front door panel 500 is provided on the side of the laundry treatment device facing the user, and a cover plate 600 is provided on the top of the laundry treatment device. The touch device 10 is installed at the connection of the front door panel 500 and the cover plate 600, which is convenient for the user to operate the touch device 10.
[0073] It should be noted that the laundry treatment device in this embodiment can be an electric appliance such as a dryer or a washer-dryer in addition to a washing machine, and this embodiment does not limit this.
[0074] It can be understood that if the touch device 10 has the beneficial effects of the above embodiment, the laundry treatment device correspondingly has the beneficial effects of the above embodiment, and its specific implementation manner can refer to the above embodiment, and this embodiment will not be elaborated herein.
[0075] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered by the protection scope of the present application.
