DETAILED DESCRIPTION

[0046] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but 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 can be combined with each other as long as they do not conflict with each other.

[0047] Household appliances are generally equipped with a display to show the selected function. Press the function option button and the display will show the corresponding content. The display is exposed on the surface of the home appliance frame and is vulnerable to direct contact with droplets or external forces. When the protective outer layer of the display is damaged, droplets will flow into the inside of the display from the damaged part, causing the components to be stained by droplets and affecting the normal use of the display, resulting in unclear display or even malfunction of the display. In addition, after the outer layer of the display is damaged, when the display is hit or subjected to other external forces, the electronic components inside are also easily damaged, which may eventually cause the display to be unclear or even completely fail.

[0048] The technical solution of the embodiment of the present application solves the problem in the prior art that the home appliance display is easily damaged by liquid contaminants and the display is unclear, which leads to inconvenience in use. 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, thereby achieving the beneficial effects that the home appliance display is not easily damaged, the display is clear and the use is convenient.

[0049] The overall idea of ​​the implementation scheme of the present invention to solve the above technical problems is as follows:

[0050] A display control device 10 is composed of a control display component 100 and a main body 200, wherein the control display component 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 formed by the image in the reflective lens 120 can be observed through the transparent touch unit 110; the display unit 130 faces the ground at a certain angle. Even if the transparent touch unit 110 is damaged, even if the liquid flows down through the damaged part of the damaged transparent touch unit 110, since the angle between the display unit 130 and the transparent touch unit 110 is an obtuse angle, the liquid cannot easily flow to the display unit 130 when flowing downward, thereby preventing the display unit 130 from being affected by the liquid that penetrates downward from the damaged transparent touch unit 110 and failing to display normally. Even if the liquid touches the display unit 130 with a low probability, since the angle between the display unit 130 and the transparent touch unit 110 is an obtuse angle and the display unit 130 faces the ground at a certain angle, the liquid quickly falls down and leaves the surface of the display unit 130 under the action of gravity, thereby effectively preventing the display unit 130 from being affected by the liquid that penetrates downward from the damaged transparent touch unit 110 and failing to display normally.

[0051] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] A display control device 10, such as Figure 1 As shown, it is composed 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 matching 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 with the horizontal direction, 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.

[0053] The transparent touch part 110, the reflective lens 120 and the display part 130 form a triangular structure 140, so that the display part 130 faces the ground at a certain angle. When the transparent touch part 110 is damaged, although the liquid may flow down through the damaged part of the damaged transparent touch part 110, since the angle between the display part 130 and the transparent touch part 110 is an obtuse angle, the display part 130 faces the ground at a certain angle, and the liquid cannot easily flow to the display part 130 when flowing downward, so that the display part 130 is not affected by the liquid that penetrates downward from the damaged transparent touch part 110 and cannot display normally, and the display part 130 is not affected by the liquid that penetrates downward and malfunctions. Even if the liquid touches the display portion 130 with a low probability, since the angle between the display portion 130 and the transparent touch portion 110 is an obtuse angle and the display portion 130 is facing the ground at a certain angle, 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 downward from the damaged transparent touch portion 110 and failing to display normally.

[0054] The touch control and implementation of the transparent touch control unit 110 is one of the following options:

[0055] 1. By using various conductors (e.g. metal, graphite, printed circuit, conductive film, etc.) to guide the touch signal from the transparent display area to the circuit board, the touch control of the transparent display screen is realized;

[0056] 2. Using short-distance contactless control (for example, 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 (for example, 1-5 cm) from the function option of the transparent touch portion 110;

[0057] 3. Use WIFI to connect remote devices or voice control to achieve contactless intelligent control.

[0058] The prior art (patent application number: 201610515035.8) discloses an induction cooker and similar heating household appliances in the prior art. Generally, the control panel is set at one end of the heating base or the electronic components with display function are set at one end of the heating base. The heat generated by the heating base during operation will be transferred to the electronic components with display function or the control panel through the same dielectric material. The electronic components with display function or the control panel are also prone to malfunction due to excessive heating. By using the control display component 100 and the main body 200 of different materials, the overheating problem caused by direct heat transfer through the same dielectric material is avoided. The design of connecting the control display component 100 and the main body 200 is adopted, instead of directly setting the control display component 100 directly in the main body 200, which increases the heat conduction distance. During the heat transfer process, increasing the length of the heat conduction path can allow more heat to be lost during the transfer process, thereby reducing the influence of the heat of the main body 200 on the display control component.

[0059] 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 .

[0060] 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 .

[0061] In order to improve the adaptability of the main body 200, the transparent touch portion 110 is provided with a plurality of control areas 111, and the control area 111 is provided with a plurality of touch buttons; the control area 111 is electrically connected to the adapter component 300. The adapter component 300 is a base component 310 with a plurality of preset functions, and the home appliances applicable to the base component 310 include one or more of an electric kettle 400, an electric medicine pot, an induction cooker or a food processor.

[0062] 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.

[0063] After the light is reflected from the mirror, it will form a double image, which may cause the image to be unclear to the eyes. For example, the content of the display unit 130 will appear double image after being reflected from the reflective lens 120. The reason for the double image is that the light is reflected twice from the upper and lower surfaces of the mirror.

[0064] To avoid unclear images, Figure 5 As shown, the reflective mirror surface 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.

[0065] The thickness distribution of the reflective lens 120 adopts a non-equivalued thickness distribution structure, so that the optical design of the reflective lens 120 reduces the double image seen by the user.

[0066] More specifically, the thickness distribution of the reflective lens has the following relationship with other variables:

[0067] T=d(tanβ2-tanα1) / (tanα2+tanβ1);

[0068] in,

[0069] T: thickness of the reflective lens;

[0070] d: The distance between the display and the reflective lens;

[0071] α1: the incident angle of light entering the reflective lens;

[0072] β1: The refraction angle of light entering the reflective lens;

[0073] α2: the incident angle of the light leaving the reflective lens;

[0074] β2: The refraction angle of the light leaving the reflective lens;

[0075] The thickness of the reflective lens is the thickness of the reflective lens where the secondary reflection occurs.

[0076] like Fig. 9As 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 double image is almost invisible to the naked eye, thereby effectively alleviating the impact of the double image.

[0077] 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.

[0078] 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 portion 110 of the display control device 10 includes a touch surface 113 and an observation surface 115, the touch portion includes a touch surface 113, and the touch surface 113 is provided with a plurality of touch keys. By touching the touch keys, the display unit 130 displays the corresponding content, and the user observes the content of the display surface of the display unit 130 imaged on the reflective lens 120 through the observation surface 115.

[0079] Specifically, the household appliance is preferably an electric kettle 400 .

[0080] More specifically, the reflective lens 120 adopts a non-equivalent thickness distribution structure to reduce the unclear situation during imaging, especially to avoid the occurrence of ghosting. The distance between the upper surface 121 and the lower surface 123 gradually increases from the display part 130 end to the transparent touch part 110 end, which is a preferred way for the reflective lens to adopt a non-equivalent thickness distribution structure.

[0081] More specifically, the display unit 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 .

[0082] 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 of the first display surface is imaged on the reflective lens 120; the second display surface 133 projects the content to be displayed to a preset projection position outside the household appliance. Among them, the preset projection position is preferably on a plane on the side of the display control device 10 away from the main body 200. The display surface to display the content is selected through the touch surface 113, and the first display surface 131 and the second display surface 133 can also be selected to display the content at the same time, and the displayed content includes but is not limited to temperature and time.

[0083] Household appliances are equipped with electronic components, which inevitably have the chance of failure, and need to be identified and repaired in advance before failure. The display control device 10 and the main body 200 are both embedded with a failure warning module. The failure warning module is provided with a warning circuit, and the distance between the wires of the warning circuit is less than the distance between the shortest wires of the working circuits of the display control device 10 and the main body 200.

[0084] Cleaning the transparent touch part 110 too frequently is not conducive to the service life of the control display assembly 100. In order to reduce the cleaning frequency and improve the stain resistance, a non-stick material is used as the material of the transparent touch part 110, such as a nano anti-adsorption material, to prevent pollutants from adhering to the surface of the transparent touch part 110. Preferably, the transparent touch part is a waterproof transparent touch part. The rest of the household appliance can also use nano anti-adsorption materials according to actual conditions.

[0085] 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.

[0086] In order to further improve the convenience of using the household appliance, the transparent touch portion 110 is also externally connected to a remote controller or a mobile device, so that the household appliance can be controlled by a mobile device such as a mobile phone, a desktop computer, a laptop computer or a tablet computer.

[0087] The display control device can be applied to different home appliances as needed. Its application in common home appliances includes applications in toasters, coffee machines, kettles, blenders, air fryers and the like.

[0088] The details are as follows:

[0089] like Fig.10 As shown, a toaster including a display control device is provided. The display control device 10 is installed on the inclined surface near the top of the front of the toaster, and its angle can be adjusted as required.

[0090] like Fig.11 As shown, a high-pressure coffee machine including a display control device is provided. A display control device 10 is installed on the front of the high-pressure coffee machine above where the coffee cups are placed, and the display control device is at a certain angle to the horizontal direction.

[0091] like Fig.12 As shown, a drip coffee machine including a display control device is provided. A display control device 10 is installed on the front of the drip coffee machine above where the coffee cup is placed, and the display control device faces upward at a certain angle.

[0092] like Fig.13 As shown, a kettle includes a display control device, and the base of the kettle is provided with a display control device 10 at a certain angle.

[0093] like Fig.14 As shown, a blender includes a display control device, and the base of the blender is provided with a display control device 10 at a certain angle.

[0094] like Fig.15 As shown, an air fryer includes a display control device, and a display control device 10 is fixed above the fryer accommodating cavity of the air fryer.

[0095] In the above embodiments, the display control device 10 is installed in a suitable place of the home appliance in a manner that it can be rotated at a certain angle according to the structure of the home appliance. Pressing the surface of the display control device 10 can achieve fine adjustment of the angle of the display control device 10. The preferred angle is 10-30 degrees, and the most preferred angle is 15 degrees.

[0096] In the above embodiments, the control modes of the display control device 10 include touch control and non-touch control, where the touch control is a conventional touch control mode. Non-touch control includes at least one of short-distance gesture control, WiFi control, PC control, and mobile control.

[0097] In summary, since the reflected light from the upper surface 121 and the lower surface 123 of the display control device 10 overlap or the ghost image is almost invisible to the naked eye, the influence of the ghost image is effectively alleviated. When the display control device 10 is applied to electrical appliances such as toasters, coffee machines, kettles, blenders, or air fryers, the ghost image problem of the display control device 10 of these electrical appliances can be avoided.
