[0002] Household electric appliances (HEA) primarily refer to various electrical and electronic devices used in homes and similar settings. They are also known as household appliances or daily appliances. They free people from arduous, tedious, and time-consuming housework, creating a more comfortable, beautiful, and healthy living and working environment. Household appliances generally have displays to indicate selected functions.

[0003] The prior art (patent application number: 201610559614.2) discloses a smart kettle including a kettle body, a temperature and time display panel, a projection box, and a projection imaging device. The projection box is provided at the bottom inner of the kettle body, and the temperature and time display panels are provided on the surface of the kettle body and in the projection box, respectively. The projection imaging device is provided in the projection box. The outer wall of the kettle body close to the projection imaging device is transparent, so as to facilitate clearer projection imaging of the temperature and time. The temperature and time display panel in the projection box is opposite to the projection imaging device, so as to facilitate projection imaging of the temperature and time. If the display panel in this technical solution is stained with water, it is easy to malfunction and cause unclear display problems. If the projection imaging device is stained with water, it is also easy to malfunction.

DETAILED DESCRIPTION

[0038] The following is a further description of specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0039] Home appliances typically feature displays to indicate selected functions. Pressing a function button displays the corresponding content. Displays exposed on the appliance's exterior are vulnerable to direct contact with droplets or external forces. If the display's protective outer layer is damaged, droplets can flow through the damaged area into the display's interior, contaminating components and affecting normal operation, resulting in unclear display or even malfunction. Furthermore, if the display's outer layer is damaged and then subjected to impact or other external forces, the electronic components within are also susceptible to damage, potentially causing the display to display unclearly or even fail completely.

[0040] The technical solution of the embodiment of the present application solves the problem in the prior art that home appliance displays are easily damaged by liquid contaminants and display is unclear, which leads to inconvenience in use by providing a display control device 10. When the transparent touch part 110, the reflective lens 120 and the display part 130 form a closed triangular structure 140 and the angle between the display part 130 and the transparent touch part 110 is an obtuse angle, the beneficial effects of the home appliance display being not easily damaged, displaying clearly and being easy to use are achieved.

[0041] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0042] A display control device 10 comprises a control display assembly 100 and a main body 200, wherein the control display assembly 100 includes a transparent touch portion 110, a reflective lens 120, and a display portion 130; the transparent touch portion 110, the reflective lens 120, and the display portion 130 form a closed triangular structure 140; the transparent touch portion 110 is inclined at a preset angle to the horizontal direction, the angle between the display portion 130 and the transparent touch portion 110 is an obtuse angle, and the two ends of the reflective lens 120 are respectively connected to the transparent touch portion 110 and the display portion 130. The content displayed on the display unit 130, as imaged by the reflective lens 120, can be viewed through the transparent touch panel 110. The display unit 130 faces the ground at a certain angle. Even if the transparent touch panel 110 is damaged, even if liquid flows down through the damaged portion of the transparent touch panel 110, the obtuse angle between the display unit 130 and the transparent touch panel 110 prevents the liquid from easily reaching the display unit 130. This prevents the display unit 130 from being affected by the liquid seeping down from the damaged transparent touch panel 110 and causing it to malfunction. Even if liquid were to touch the display unit 130 in the unlikely event that it were to do so, the obtuse angle between the display unit 130 and the display unit 130, coupled with the angle facing the ground, means that gravity quickly pulls the liquid away from the surface of the display unit 130, effectively preventing the liquid seeping down from the damaged transparent touch panel 110 from affecting the display unit 130 and causing it to malfunction.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] A display control device 10, such as Figure 1 As shown, it consists of a control display component 100 and a main body 200, and the control display component 100 is connected to the main body 200; the main body 200 is externally connected to a power supply and is provided with an adapter component 300 that matches the home appliance; the control display component 100 is electrically connected to the adapter component 300 to operate the adapter component 300; the control display component 100 includes a transparent touch part 110, a reflective lens 120 and a display part 130; the transparent touch part 110, the reflective lens 120 and the display part 130 form a triangular structure 140; the transparent touch part 110 is at a preset inclination angle to the horizontal direction, and the angle between the display part 130 and the transparent touch part 110 is an obtuse angle, and the two ends of the reflective lens 120 are respectively connected to the transparent touch part 110 and the display part 130; the content displayed by the display part 130 appearing in the reflective lens 120 is observed through the transparent touch part 110.

[0045] The transparent touch panel 110, the reflective lens 120, and the display panel 130 form a triangular structure 140, which allows the display panel 130 to face the ground at a certain angle. If the transparent touch panel 110 is damaged, liquid may flow down through the damaged portion of the transparent touch panel 110. However, due to the obtuse angle between the display panel 130 and the transparent touch panel 110, the display panel 130 faces the ground at a certain angle, and the liquid cannot easily flow down to the display panel 130. This prevents the display panel 130 from being affected by the liquid seeping down from the damaged transparent touch panel 110, causing it to malfunction. Even if liquid does get on the display portion 130 with a low probability, the angle between the display portion 130 and the transparent touch portion 110 is obtuse, and the display portion 130 is facing the ground at a certain angle. Therefore, the liquid will quickly fall down and leave the surface of the display portion 130 under the action of gravity, effectively preventing the display portion 130 from being affected by the liquid that penetrates from the damaged transparent touch portion 110 and thus failing to display normally.

[0046] The touch control and implementation of the transparent touch portion 110 is one of the following options:

[0047] 1. Touch control of the transparent display screen is achieved by using various conductors (such as metal, graphite, printed circuit, conductive film, etc.) to guide the touch signal from the transparent display area to the circuit board;

[0048] 2. Using short-range contactless control (e.g., including but not limited to infrared, light sensors, etc.), the user can achieve contactless control of the transparent display screen by clicking with a finger at a certain distance (e.g., 1-5 cm) from the function option of the transparent touch portion 110;

[0049] 3. Use WIFI to connect to remote devices or voice control to achieve contactless intelligent control.

[0050] The prior art (patent application number: 201610515035.8) discloses an induction cooker and similar heating appliances in the prior art. A control panel or electronic components with a display function are typically located at one end of the heating base. Heat generated by the heating base during operation is transferred to the electronic components with a display function or the control panel through the same dielectric material. Excessive heat exposure to the electronic components with a display function or the control panel can easily cause malfunction. By using different materials for the control and display assembly 100 and the main body 200, overheating caused by direct heat transfer through the same dielectric material is avoided. By connecting the control and display assembly 100 to the main body 200, rather than directly placing the control and display assembly 100 within the main body 200, the heat conduction path is increased. Increasing the heat conduction path allows more heat to be lost during the heat transfer process, thereby reducing the impact of the heat from the main body 200 on the display and control assembly.

[0051] To avoid malfunction of the display control components after they get wet, Figure 2 As shown, the inner cavity 141 of the triangular structure 140 is preferably a waterproof and sealed inner cavity 141 to prevent liquid from entering the triangular structure 140 .

[0052] like Figure 3 As shown, the transparent touch portion 110 is provided with at least one control area 111; the adapter component 300 is a base component 310 having at least one preset function. Among them, the preset function preferably includes heating and rotation, and the preset function more preferably includes both heating and rotation functions. Figure 4 As shown, the heating base assembly 311 , the rotating base assembly 313 and the heating rotating base assembly 315 can all serve as preset functions of the base assembly 310 .

[0053] To improve the adaptability of the main body 200, the transparent touch portion 110 is provided with multiple control areas 111, each of which has multiple touch buttons. The control areas 111 are electrically connected to the adapter assembly 300. The adapter assembly 300 is a base assembly 310 with multiple preset functions. The base assembly 310 can be used with one or more household appliances including an electric kettle 400, an electric medicine pot, an induction cooker, or a food processor.

[0054] The reflective lens 120 of the control display assembly 100 is used to image the content of the display unit 130 and reflect it into the user's eyeball. The reflective lens 120 is a lens. The reflective lens 120 can be a convex lens, a plane mirror, or an irregular lens. Specifically, the reflective lens 120 is divided into an upper surface 121 and a lower surface 123.

[0055] When light reflects off a mirror, it creates ghosting images, potentially blurring the view. For example, the content on display 130 may appear ghosted after being reflected off mirror 120. Ghosting occurs when light reflects twice, on both the upper and lower surfaces of the mirror.

[0056] To avoid unclear images, Figure 5 As shown, the reflective mirror is designed as follows: the distance between the upper surface 121 and the lower surface 123 is different. Preferably, the distance between the upper surface 121 and the lower surface 123 gradually increases from the display portion 130 end to the transparent touch portion 110 end.

[0057] The thickness distribution of the reflective lens 120 adopts a non-uniform thickness distribution structure, so that the optical design of the reflective lens 120 reduces the double image seen by the user.

[0058] More specifically, the thickness distribution of the reflective lens has the following relationship with other variables:

[0059] T=d(tanβ2-tanα1) / (tanα2+tanβ1);

[0060] in,

[0061] T: thickness of the reflective lens;

[0062] d: The distance between the display and the reflective lens;

[0063] α1: the incident angle of light entering the reflective lens;

[0064] β1: the refraction angle of light entering the reflective lens;

[0065] α2: the incident angle of the light leaving the reflective lens;

[0066] β2: the refraction angle of the light leaving the reflective lens;

[0067] The thickness of the reflective lens is the thickness of the reflective lens where the secondary reflection occurs.

[0068] like Figure 9 As shown, when the light reaches the upper surface 121 and the lower surface 123, because the thickness distribution of the reflective lens 120 adopts a non-equivalent thickness distribution structure, the reflected light on the upper surface 121 and the lower surface 123 overlap or the ghosting is almost invisible to the naked eye, thereby effectively alleviating the impact of ghosting.

[0069] The embodiment of the present invention further provides a household appliance, such as Figure 6 As shown, it includes the above display control device 10.

[0070] Specifically, the adapter component 300 of the display control device 10 is one or more of a heating module, a stirring module or a heating and stirring module, and the module is adapted to a heating container and / or a stirring container; the transparent touch part 110 of the display control device 10 includes a touch surface 113 and an observation surface 115, the touch part includes a touch surface 113, and the touch surface 113 is provided with multiple touch keys. By touching the touch keys, the display part 130 displays the corresponding content, and the user observes the content of the display surface of the display part 130 imaged on the reflective lens 120 through the observation surface 115.

[0071] Specifically, the household appliance is preferably an electric kettle 400 .

[0072] More specifically, the reflective lens 120 utilizes a non-uniform thickness distribution structure to mitigate image blur, particularly preventing ghosting. The distance between the upper surface 121 and the lower surface 123 gradually increases from the display portion 130 toward the transparent touch portion 110, a preferred embodiment of the non-uniform thickness distribution structure for the reflective lens.

[0073] More specifically, the display portion 130 includes a first display surface 131 ; the first display surface 131 forms an obtuse angle with the reflective lens 120 , and the display content of the first display surface is imaged on the reflective lens 120 .

[0074] Especially specific, such as Figure 7 As shown, the display unit 130 includes a first display surface 131 and a second display surface 133. The first display surface 131 forms an obtuse angle with the reflective lens 120, and the display content on the first display surface is imaged by the reflective lens 120. The second display surface 133 projects the content to be displayed onto a predetermined projection position outside the household appliance. The predetermined projection position is preferably located on a plane on the side of the display control device 10 away from the main body 200. The touch screen 113 is used to select the display surface to display content, and content can also be displayed simultaneously on both the first and second display surfaces 131, 133. The displayed content includes, but is not limited to, temperature and time.

[0075] Household appliances contain electronic components, which inevitably experience failures. This requires proactive identification and repair before a failure occurs. Both the display control device 10 and the main body 200 have built-in failure warning modules. These modules include a warning circuit, where the distance between the wires in the warning circuit is smaller than the distance between the shortest wires in the operating circuits of the display control device 10 and the main body 200.

[0076] Frequent cleaning of the transparent touch panel 110 is detrimental to the lifespan of the display assembly 100. To reduce cleaning frequency and improve stain resistance, the transparent touch panel 110 is made of a non-stick material, such as a nano-anti-adsorption material, to prevent contaminants from adhering to the surface of the transparent touch panel 110. Preferably, the transparent touch panel is waterproof. Other areas of the household appliance can also use nano-anti-adsorption materials as needed.

[0077] In the embodiment of the present invention, the electric kettle 400 is a preferred embodiment, and its main components are as follows: Figure 8 shown.

[0078] In order to further improve the convenience of using the home appliance, the transparent touch portion 110 is also connected to an external remote control or mobile device, so that the home appliance can be controlled by a mobile device such as a mobile phone, desktop computer, laptop computer or tablet computer.

[0079] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
