Description

Screen assembly of washing equipment and washing equipment Technical Field

[0001] The present invention belongs to the technical field of washing equipment, and in particular relates to a screen assembly of washing equipment and the washing equipment. Background Art

[0002] At present, most washing equipment is equipped with a color screen layer and a touch screen layer. The color screen layer displays images and text through the working principle of the liquid crystal screen. The working principle of the liquid crystal screen is: the backlight illuminates the liquid crystal molecules in the color screen layer, and the rotation degree of the liquid crystal molecules is controlled by applying an electric field, thereby adjusting the transmittance of light, so that the light passing through the liquid crystal molecules passes through different filters, and then combines to form different images.

[0003] However, since light must pass through the color screen layer and the touch screen layer first, and then to the decorative panel, and the color screen layer is pasted on the frame, and the touch screen layer is pasted on the decorative panel, there must be an air gap when the color screen layer and the touch screen layer are in contact. In addition, the alignment accuracy of the color screen layer and the decorative panel is insufficient, resulting in problems such as ghosting, incomplete display, and unclear display, which greatly affects the display effect of images and text.

[0004] In view of this, the present invention is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0061] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0062] As shown in Figures 1 to 10, the screen assembly of a washing device and the washing device of the present invention are affixed to a decorative panel 1 or a frame 5 by a touch screen layer 2 and a color screen layer 3, thereby reducing the air gap between the color screen layer 3 and the touch screen layer 2. The decorative panel 1 is fixed to the frame 5 through a plug-in structure, so that the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3 and the functional division area of ​​the decorative panel 1 are aligned, thereby ensuring a better display effect of the washing device screen.

[0063] Example 1

[0064] As shown in Figures 1 to 10, this embodiment provides a screen assembly for washing equipment. The screen assembly comprises, from top to bottom, a decorative panel 1, a touchscreen layer 2, a color screen layer 3, and a frame 5. The decorative panel 1 reflects touchscreen actions on the touchscreen layer 2, while the decorative panel 1 displays the projection of light generated by the color screen layer 3. The touchscreen layer 2 and color screen layer 3 are both mounted on the decorative panel 1 or the frame 5. The decorative panel 1 is secured to the frame 5 via a plug-in structure, aligning the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3, and the functionally divided areas of the decorative panel 1.

[0065] In this embodiment, it is stipulated that the side of each component facing the outer surface of the decorative panel 1 is its top layer, and the side of each component facing the inner surface of the frame 5 is its bottom layer.

[0066] Specifically, the touchscreen layer 2 is a capacitive touchscreen or a resistive touchscreen. When the touchscreen layer 2 is a capacitive touchscreen, it utilizes the human body's current induction phenomenon to form a capacitor between the finger and the screen. When a finger touches the screen, a small current is drawn away. This current causes current to flow through the four electrodes on the touchpad. The controller then calculates the coordinates of the touch point by calculating the ratio of these four currents. When the touchscreen layer 2 is a resistive touchscreen, when a finger touches the decorative panel 1, the two conductive layers of the touchscreen layer 2 make contact at the touch point, causing a change in resistance and generating signals in both the X and Y directions. These signals are then sent to the touchscreen controller, which detects this contact and calculates the coordinates of the touch point. Therefore, when the touchscreen layer 2 is placed on the bottom layer of the decorative panel 1, for example, by affixing it to the decorative panel 1 using specialized glue, the decorative panel 1 not only provides protection but also effectively reflects the user's touch action on the touchscreen layer 2, ensuring that the touchscreen layer 2 accurately reflects the coordinates of the touch point.

[0067] Specifically, the color screen layer 3 is preferably a liquid crystal display, comprising liquid crystals disposed between two transparent substrates. Backlight is transmitted through the color screen layer 3, generating text or images that are projected onto the functionally divided areas of the decorative panel 1 for display. Furthermore, the functionally divided areas of the decorative panel 1 display content, such as water level, temperature, drum speed, and the current wash stage, with the color screen layer 3 generating text or images in the functional display areas corresponding to the functionally divided areas.

[0068] As a specific implementation of this embodiment, the user selects washing mode, rinsing mode and drying mode, etc. through touch screen actions or the knob on the decorative panel 1, such as quick wash, energy-saving wash, single dehydration, single drying, etc., and the water level, temperature, drum speed, current washing stage, etc. are displayed through the color screen layer 3 during the washing process of the washing equipment.

[0069] In the solution of this embodiment, the touch screen layer 2 and the color screen layer 3 are jointly arranged on the decorative panel 1 or the frame 5, thereby reducing the air gap between the color screen layer 3 and the touch screen layer 2. The decorative panel 1 is fixed to the frame 5 through a plug-in structure, so that the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3 and the functional division area of ​​the decorative panel 1 are aligned, thereby ensuring a better display effect of the washing equipment screen.

[0070] In this embodiment, the color screen layer 3 is fixed to the bottom surface of the touch screen layer 2, and the touch screen layer 2 or the color screen layer 3 is adhered to the decorative panel 1; a notch 21 is provided on the touch screen layer 2, and the notch 21 is aligned with the functional display area of ​​the color screen layer 3, so that the light generated by the color screen layer 3 passes through the notch 21 and is projected onto the decorative panel 1.

[0071] As a specific implementation of this embodiment, when the top layer area of ​​the color screen layer 3 is larger than the surface area of ​​the touch screen layer 2, the color screen layer 3 is adhered to the decorative panel 1 with special glue, and the touch screen layer 2 is clamped and fixed by the decorative panel 1 and the color screen layer 3.

[0072] In this embodiment, the top layer of the color screen layer 3 is a transparent substrate, and the transparent substrate is fixed to the bottom surface of the touch screen layer 2 .

[0073] In this embodiment, the surface of the touch screen layer 2 includes a thin film layer, which covers the notch 21. The touch screen layer 2 is provided with a notch 21 in the functional display area of ​​the color screen layer 3 to expose the thin film layer; the transparent substrate of the color screen layer 3 is adhered to the bottom surface of the touch screen layer 2 and the thin film layer in the notch 21 of the touch screen layer 2 as a whole.

[0074] By gluing the transparent substrate of the color screen layer 3 to the bottom surface of the touch screen layer 2 and the thin film layer in the gap 21 of the touch screen layer 2, the cost of setting the color screen layer 3 and the touch screen layer 2 for the washing equipment is reduced, and the light passing through the color screen layer 3 has to pass through one less transparent substrate or thin film layer when reaching the decorative panel 1, thereby achieving a better display effect on the screen of the washing equipment.

[0075] Furthermore, the notch 21 makes the touch screen area 22 of the touch screen layer 2 and the functional display area of ​​the color screen layer 3 not overlap. The touch screen area 22 of the touch screen layer 2 includes an ITO (Indium Tin Oxide) film and a thin film layer, and the thin film layer is arranged on the surface of the ITO film; the color screen layer 3 is a liquid crystal display structure, and the thin film layer in the notch 21 of the touch screen layer 2 replaces the transparent substrate of the liquid crystal display structure; the thin film layer includes a PET (Polyethylene terephthalate) substrate, or is made of PET.

[0076] Through the above scheme, the thin film layer in the gap 21 of the touch screen layer 2 replaces the transparent substrate of the liquid crystal display structure of the color screen layer 3, and the color screen layer 3 and the touch screen layer 2 are integrated by sharing a thin film layer of PET material, which reduces the cost of setting the color screen layer 3 and the touch screen layer 2 in the washing equipment, and makes the light pass through one less transparent substrate or film layer when reaching the decorative panel 1, further ensuring that there is no air gap between the color screen layer 3 and the touch screen layer 2, and achieving a better display effect on the screen of the washing equipment.

[0077] In this embodiment, the bottom surface area of ​​the touch screen layer 2 is the same as the top surface area of ​​the color screen layer 3. When the bottom surface of the touch screen layer 2 and the top surface of the color screen layer 3 are in contact, the touch screen layer 2 and the color screen layer 3 are aligned at the corresponding positions, and the functional display area of ​​the color screen layer 3 is aligned with the notch 21.

[0078] Furthermore, the top to bottom areas of the touch screen layer 2 and the color screen layer 3 are consistent, that is, when the color screen layer 3 is adhered to the bottom surface of the touch screen layer 2, the thin film layer in the notch 21 of the touch screen layer 2 replaces the transparent substrate of the liquid crystal display structure of the color screen layer 3, thereby realizing an integrated structure of the touch screen layer 2 and the color screen layer 3.

[0079] In one embodiment of the present invention, the plug-in structure includes a claw 11 and a socket 51. In one embodiment, the claw 11 is provided on the frame 5, and the socket 51 is provided on the decorative panel 1. In another embodiment, the socket 51 is provided on the frame 5, and the claw 11 is provided on the decorative panel 1.

[0080] The frame 5 includes a through-hole and a frame plate 4 disposed within the through-hole. The frame plate 4 is provided with a backlight channel 41. The decorative panel 1 is secured to the frame 5 via latches 11 and latches 51, with the backlight channel 41 aligned with the functionally defined areas on the decorative panel 1. This ensures a stable attachment of the decorative panel 1 to the frame 5, aligning the backlight channel 41 of the frame plate 4, the functional display area of ​​the color screen layer 3, and the functionally defined areas of the decorative panel 1, achieving a superior display quality on the washing machine screen.

[0081] Specifically, the frame plate 4 abuts against the circumferential side wall of the opening of the frame 5 .

[0082] In a detailed structure of this embodiment, the claw 11 is provided on the decorative panel 1, and the latch 51 is provided on the frame 5 near the through opening. The claw 11 includes an extension extending through the latch 51 and a hook extending radially outward from the latch 51. The hook engages with the latch 51 to secure the color screen layer 3 to the frame panel 4, with the functional display area of ​​the color screen layer 3 aligned with the backlight channel 41. This structure further ensures a secure fit between the claw 11 and the latch 51, thereby further ensuring the stable fixation of the decorative panel 1 to the frame 5.

[0083] In another embodiment of this embodiment, the plug-in structure includes a threaded seat 12, a first threaded hole 53, a second threaded hole 43, and a connector. The threaded seat 12 is provided on the decorative panel 1, and a first threaded hole 53 corresponding to the threaded seat 12 is provided near the opening of the frame 5. The second threaded hole 43 corresponding to the first threaded hole 53 is provided on the frame panel 4. The connector passes through the second threaded hole 43, the first threaded hole 53, and the threaded seat 12, aligning the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3, and the functionally divided areas of the decorative panel 1.

[0084] Specifically, the connecting member is a screw or a bolt, preferably a screw.

[0085] In the above solution, the decorative plate 1 and the frame plate 4 are positioned and fixed on the frame 5 through the threaded seat 12 , the first threaded hole 53 , the second threaded hole 43 and the connecting piece.

[0086] Furthermore, at least two threaded seats 12 are provided on the decorative panel 1, and at least two first threaded holes 53 surrounding the through opening are provided on the frame 5; at least two connecting members are respectively passed through the second threaded hole 43, the first threaded hole 53 and the threaded seat 12, so that the relative positions of the frame plate 4 and the decorative panel 1 and the frame 5 remain unchanged.

[0087] In detail, the relative position of the threaded seat 12 and the functional division area on the decorative panel 1 is the same as the relative position of the second threaded hole 43 and the backlight channel on the frame panel 4, thereby ensuring that the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3 and the functional division area of ​​the decorative panel 1 are aligned.

[0088] Through the above solution, it is further ensured that the decorative panel 1 is stably fixed on the frame 5 , and at the same time, the decorative panel 1 and the frame panel 4 are further accurately and stably positioned and fixed on the frame 5 .

[0089] In the detailed solution of this embodiment, the plug-in structure includes a combination of the claw 11 and the bayonet 51, and a combination of the threaded seat 12, the first threaded hole 53, the second threaded hole 43 and the connector. The two plug-in structures are arranged at different positions.

[0090] Specifically, as shown in FIG7 , twelve claws 11 are provided around the edge of the decorative panel 1, with six claws 11 on the upper side, five claws 11 on the lower side, and one claw 11 on the right side. These claws 11 are Z-shaped protrusions on the surface of the decorative panel 1, with ten of these protrusions extending toward the periphery of the decorative panel 1 and two protruding toward the center of the decorative panel 1. Furthermore, reinforcing ribs are provided on the claws 11 to enhance their structural strength and make them less susceptible to bending and damage.

[0091] The threaded seat 12 is arranged in an area close to the edge of the decorative plate 1, but closer to the center relative to the claw 11. The threaded seat 12 is specifically arranged in the right half area of ​​the upper and lower edges of the decorative plate 1, and is staggered with the claw 11 in the length direction of the decorative plate 1.

[0092] In this embodiment, the screen assembly has a main control circuit board, which is arranged on the bottom side of the frame 5, abuts against the frame 5, and passes through the frame 5 to connect with the touch screen layer 2 and the color screen layer 3; the main control circuit board is used to control the touch screen layer 2 and the color screen layer 3, and generate a light source acting on the color screen layer 3.

[0093] In this embodiment, the circumferential sidewall protrusions of the notch 21 of the frame 5 form a circuit board abutment portion 54, and the frame plate 4 is provided with a through opening around the abutment portion 54. This ensures that the light source generated by the main control circuit board is aligned with the functional display area of ​​the color screen layer 3.

[0094] In this embodiment, the frame plate 4 is provided with a raised backlight channel 41, which corresponds to the functional display area of ​​the color screen layer 3; and a light-isolating sponge is provided between adjacent backlight channels 41, further ensuring that the functional display area of ​​the color screen layer 3 is free of light crosstalk.

[0095] In this embodiment, a raised digital tube 42 is provided on the frame plate 4 .

[0096] In this embodiment, the screen assembly of the washing machine has the following specific structure: as shown in Figures 2 to 5, the frame plate 4 is clamped to the through-hole of the frame 5. As shown in Figures 4 and 5, the frame plate 4 is provided with at least seven limiting openings 44 facing the inside of the frame 5, and the frame 5 is provided with at least seven circuit board fixing brackets 52 facing the inside of the frame 5. Each circuit board fixing bracket 52 passes through the limiting opening 44. The limiting opening 44 is concave or convex. The circuit board fixing bracket 52 is clamped through the limiting opening 44, and the main control circuit board is fixed to the bottom of the frame plate 4 through the circuit board fixing bracket 52, so that the frame plate 4 is clamped to the through-hole of the frame 5. The through-hole of the frame 5 is also provided with an abutment 54, which extends from the side wall of the through-hole toward the center of the through-hole to form the abutment 54 for clamping the frame plate 4. The frame plate 4 is flush with the surface of the color screen layer 3, and its surface is recessed downward to provide a limit opening 44 and a second threaded hole 43 surrounding the surface. The second threaded hole 43 is aligned with the first threaded hole 53 of the frame 5, so that the screw passes through the second threaded hole 43 and the first threaded hole 53 in sequence from the inner side of the frame 5 until it extends into the threaded seat 12 of the decorative plate 1, thereby achieving accurate and stable fixation of the frame plate 4 on the frame 5.

[0097] As shown in Figures 6 to 9, the Z-shaped protrusion 11 extending inward from the decorative panel 1 passes through the slot 51 close to the through-hole of the frame 5, so that the top of the claw 11 abuts against the edge of the slot 51, preventing the bolts from loosening and causing the decorative panel 1 to cause the touch screen layer 2 and color screen layer 3 attached thereto to deviate from the backlight channel 41 of the frame panel 4.

[0098] As shown in Figure 1, the decorative panel 1 has non-overlapping digital tube display areas, touch screen areas 22, color screen display areas and a first knob seat 13. The first knob seat 13 corresponds to the second knob seat 45 of the frame plate 4, so that the rotating shaft of the knob can pass through the first knob seat 13 and the second knob seat 45, and the knob cover can rotate on the first knob seat 13. The color screen display area corresponds to the notch 21 of the touch screen layer 2 and the backlight channel 41 of the frame plate 4. Two rows of 7 independent rectangular color screen display areas are set in the lower part of the decorative panel 1, and 6 independent rectangular color screen display areas are set on the upper side of the upper row. In addition, 3 larger color screen display areas are set, and the digital tube display area is set on the upper part of the frame plate 4.

[0099] As shown in Figures 1 and 10, the color screen layer 3 is a liquid crystal display structure, which includes a transparent substrate, a black matrix, a CF (Color Filter) layer, a protective layer and an ITO film. The original transparent substrate on the top is removed and replaced with a thin film layer in the gap 21 of the touch screen layer 2, so that the color screen layer 3 can be attached to the touch screen layer 2 without an air gap and integrated with the touch screen layer 2. The effect of the integrated arrangement of the color screen layer 3 and the touch screen layer 2 is shown in Figure 10, which can greatly improve the display effect of the functional display area of ​​the rectangular color screen layer 3 in Figure 10.

[0100] In this embodiment, the screen assembly of the washing machine operates as follows: the main control circuit board emits light to control the display content of the color screen layer 3, receives response signals from the touch screen layer 2, and generates the coordinates of the touch point. The light from the main control circuit board passes through the backlight channel 41 of the frame plate 4 and is projected onto the color screen layer 3. By changing the light transmittance of the liquid crystal in the color screen layer 3, the color screen layer 3 produces different images, which are displayed on the functionally divided display area of ​​the decorative plate 1 through the notch 21 of the touch screen layer 2.

[0101] The digital tube 42 on the frame plate 4 is displayed on the decorative plate 1 through the color screen layer 3 and the touch layer;

[0102] The decorative panel 1 better reflects the user's touch screen action on the touch screen layer 2, and the touch screen layer 2 transmits the response signal to the main control circuit board.

[0103] In this embodiment, the touch screen layer 2 and the color screen layer 3 are adhered to the decorative panel 1 or the frame 5, so that the air gap between the color screen layer 3 and the touch screen layer 2 is reduced, and the decorative panel 1 is fixed to the frame 5 through a plug-in structure, so that the backlight channel 41 of the frame 5, the functional display area of ​​the color screen layer 3 and the functional division area of ​​the decorative panel 1 are aligned, thereby ensuring a better display effect of the washing device screen; the transparent substrate of the color screen layer 3 is adhered to the bottom surface of the touch screen layer 2 and the thin film layer in the notch 21 of the touch screen layer 2, thereby reducing the cost of setting the color screen layer 3 and the touch screen layer 2 for the washing device, so that the light passing through the color screen layer 3 passes through one less transparent substrate or thin film layer when reaching the decorative panel 1, thereby achieving a better display effect of the washing device screen.
