[0041] Specifically, the indicator lamp in the light collecting groove 13 is installed at the groove bottom of the light collecting groove 13.

[0042] The above arrangement can fully exert the light collecting effect of the light collecting groove 13, prolong the light path length of the indicator lamp in the light collecting groove 13, concentrate the light emitted by the indicator lamp as much as possible, make the light projected by the light collecting groove 13 to the display panel 2 more concentrated on the display panel 2, and make the highlighting effect of the font on the display panel 2 better.

[0043] It can be understood that the vertex of the indicator lamp installed in the light collecting groove 13 is lower than the groove opening of the light collecting groove 13, so that the light collecting groove 13 can fully concentrate the light emitted by the indicator lamp, and at the same time avoid interference between the indicator lamp and the bottom surface of the display panel 2.

[0044] In an optional embodiment, the top surface of the base 1 is provided with a groove 12, the display panel 2 is inserted into the groove 12, and the groove bottom of the groove 12 is provided with the light collecting groove 13 and the light guide groove 11.

[0045] In the above embodiment, the light collecting groove 13 and the light guide groove 11 are both provided at the groove bottom of the groove 12, and the light emitted by the light collecting groove 13 and the light guide groove 11 can be simultaneously projected to the display panel 2 from the bottom surface of the display panel 2, which is convenient for processing of the light collecting groove 13 and the light guide groove 11, and convenient for installation of the display panel 2.

[0046] In an optional embodiment, as shown, Figure 1 the groove 12 penetrates through both sides of the base 1 along the extension direction of the groove 12, and the depth of the groove 12 can be adjusted according to the size of the display panel 2.

[0048] The display panel 2 can be fixed to the base 1 by means of glue or a clamping groove.

[0049] Of course, the recess 12 can also be formed on the side surface of the base 1, so that the display part 21 of the display panel 2 can protrude from the side of the base 1.

[0050] In an optional embodiment, the opening of the light guide groove 11 at the bottom of the recess 12 is a first opening, and the opening of the light collecting groove 13 at the bottom of the recess 12 is a second opening, and the first opening and the second opening are independently arranged.

[0051] In an optional embodiment, as shown in Figure 1 , the light collecting groove 13 is located on one side of the light guide groove 11 along the extension direction of the bottom surface of the display panel 2.

[0052] The above arrangement can make the light in the light collecting groove 13 and the light in the light guide groove 11 irradiate to the inside of the display panel 2 from different positions of the display panel 2 along the extension direction of the display panel 2, and the display surface of the display panel 2 can display different light effects.

[0053] In an optional embodiment, as shown in Figure 1 and Figure 2 , when the state indicator lamp group 321 is configured as multiple groups, the multiple groups of state indicator lamp groups 321 are arranged at intervals along the length direction of the bottom surface of the display panel 2.

[0054] The above embodiment can make each group of state indicator lamp groups 321 correspond to different areas on the display panel 2, and when the indicator lamps in each group of state indicator lamp groups 321 located in the light guide groove 11 flash at the same time, the light can uniformly illuminate the entire display panel 2.

[0055] On the basis of the above embodiment, the two indicator lamps close to each other in the two adjacent groups of state indicator lamp groups 321 are installed in the light guide groove 11 of each group, or are installed in the light collecting groove 13 of each group, or one is installed in the light guide groove 11 and the other is installed in the light collecting groove 13.

[0056] That is, whether the two indicator lamps close to each other in the two adjacent groups of state indicator lamp groups 321 are installed in the light guide groove 11 or the light collecting groove 13 is not limited, and the user can select according to actual needs.

[0057] In an optional embodiment, the display panel 2 can be made of transparent materials such as glass, plastic, etc.

[0058] In a preferred embodiment, the display panel 2 is made of glass and uses light and the glass panel for display. Compared with the kitchen appliance control touch panel, it has a simpler appearance, can display more information on the glass panel, is more elegant, and is more suitable for nighttime operation.

[0059] Specifically, the display panel 2 includes a display part 21 and a plug part 22 connected to the display part 21. The plug part 22 is inserted into the groove 12 of the base 1 and is arranged opposite to the status indicator light group 321. The display part 21 protrudes from the base 1. The display part 21 can switch the font color and / or brightness of the displayed kitchen appliance 4 function under different lighting conditions.

[0060] In the aforementioned display device, the connector 22 in the display panel 2 can be directly inserted into the groove 12 of the base 1. Compared to connecting with screws, pins, or other connectors, this method is more convenient and aesthetically pleasing. Furthermore, the groove 12 can accommodate display panels 2 of the same size but with different fonts, offering greater flexibility in use.

[0061] In an optional embodiment, the display section 21 of the display panel 2 is printed with silkscreen information displaying kitchen appliances. The silkscreen is used to display different colors and / or brightness under different lighting conditions.

[0062] For example, under white light, the user can see the silkscreen on the display unit 21, and under red light, the silkscreen changes to red; as another example, under low-brightness red light, the silkscreen is a weaker red, and under high-brightness red light, the silkscreen is a stronger red.

[0063] The above settings allow users to identify the kitchen appliance information corresponding to the silkscreen based on changes in color or brightness. The kitchen appliance information may include the type of kitchen appliance and / or its function, but is not limited to the above information.

[0064] When the status indicator light group 321 is configured as multiple groups, the silkscreen on the display unit 21 can be configured as multiple, each silkscreen corresponds to a group of status indicator light groups 321, each silkscreen can correspond to a function of the kitchen appliance, and different silkscreens correspond to different functions.

[0065] The display device may also include a control component 31 and multiple sensing components. Each sensing component and a set of status indicator lights 321 constitute a light-emitting component 32, which is connected to the control component 31. In use, such as... Figure 3 As shown, the sensing component is used to generate a trigger signal based on the user's touch, and the control component 31 is used to control the status indicator group 321 to switch the light status and switch the operation status of the corresponding kitchen appliance 4 based on the trigger signal.

[0066] Among them, such as Figure 4As shown, the sensing assembly can include a front sensing structure 322 and a back sensing structure 323, both of which are connected with the control assembly 31, and are distributed on both sides of the state indicator light group 321 along a direction perpendicular to the plane where the display panel 2 is located, and are both used to generate a trigger signal according to the user's touch.

[0067] The above-mentioned embodiments can allow the user to trigger the sensing assembly from any one of the front and back of the display panel 2, facilitating the user's operation.

[0068] In optional embodiments, the top surface of the base 1 on one side of the display panel 2 is used for the user to touch and make the front sensing structure 322 generate a trigger signal, and the top surface of the base 1 on the other side of the display panel 2 is used for the user to touch and make the back sensing structure 323 generate a trigger signal; as Figure 2 As shown, the front sensing structure 322 and the back sensing structure 323 can each include an infrared emitter lamp 3231 and an infrared receiver lamp 3232, both of which are arranged in the base 1 and are connected with the control assembly 31.

[0069] In use, the user can touch the top surface of the base 1 on any one side of the display panel 2 to trigger the front sensing structure 322 or the back sensing structure 323, and the infrared emitter lamp 3231 and the infrared receiver lamp 3232 generate a trigger signal based on the user's touch, which is simple and convenient to operate.

[0070] In optional embodiments, as Figure 4 As shown, the control assembly 31 can include an MCU microcontroller unit and a wireless transmitter 312.

[0071] When the user's finger touches a position on the top surface opposite to a certain front sensing structure 322 or back sensing structure 323, the sensing structure outputs a trigger signal to the MCU 311, the MCU 311 sends a control signal to the external kitchen electrical equipment 4 based on the wireless transmitter 312, the kitchen electrical equipment 4 performs an operation corresponding to the trigger signal based on the control signal, and at the same time, the MCU 311 controls the state indicator light group 321 corresponding to the sensing structure to switch the light state based on the wireless transmitter 312, and the state indicator light group 321 illuminates the corresponding silk screen.

[0072] It should be noted that the principle of the MCU 311 and the wireless transmitter 312 controlling the corresponding equipment or electronic device to work according to the trigger signal is a known technology in the prior art, and the above-mentioned trigger signal can be but is not limited to the signal triggered by the button, the signal triggered by the touch screen. For example, according to the remote control to control the on-off of the TV, according to the mobile phone terminal to control the on-off of the sweeping robot, etc.

[0073] In an optional embodiment, the top surface of the base 1 is concavely provided with a mounting groove, and the infrared emitting lamp 3231 and the infrared receiving lamp 3232 are mounted in the mounting groove. The mounting groove can be, but is not limited to, a square groove or a circular groove, which facilitates the stable fixation of the infrared emitting lamp 3231, the infrared receiving lamp 3232 and the state indicating lamp group 321, and the groove-shaped structure is easy to process. The touch action can only trigger the front sensing structure 322 or the back sensing structure 323 from one end of the groove, which is conducive to the infrared sensing and has strong anti-interference ability.

[0074] In an optional embodiment, as shown in Figure 2 the state indicating lamp group 321 includes a first lamp body 3211 and a second lamp body 3212, both of which are connected with the control assembly 31. The first lamp body 3211 and the second lamp body 3212 have different light colors. One of the first lamp body 3211 and the second lamp body 3212 is arranged in the light guide groove 11, and the other is arranged in the light collecting groove 13. The control assembly 31 is used to control one of the first lamp body 3211 and the second lamp body 3212 to flash according to the trigger signal.

[0075] Among them, the first lamp body 3211 can be a white lamp, and the second lamp body 3212 can be a red lamp. During work, the control assembly 31 controls the two lamps to be lit at different times, and at least one lamp is lit. Figure 2 For example, when the display device is powered on and works, the six first lamp bodies 3211 emit light, and the white lamp illuminates the display panel 2. The user can see each silk screen on the display panel 2 through the white light. The user can trigger the front sensing structure 322 or the back sensing structure 323 corresponding to the required function according to the function of the kitchen electrical appliance shown by the silk screen. The MCU 311 sends a control signal to the external kitchen electrical appliance 4 based on the wireless transmitter 312 according to the trigger signal. The kitchen electrical appliance 4 performs an operation corresponding to the trigger signal based on the control signal. At the same time, the MCU 311 controls the first lamp body 3211 to be extinguished and the second lamp body 3212 to be lit based on the wireless transmitter 312 according to the trigger signal. The corresponding silk screen changes to red under the irradiation of the red lamp, indicating that the user is currently operating the corresponding function of the corresponding kitchen electrical appliance.

[0076] Preferably, the white lamp is placed in the light guide groove 11, which can make the entire brightness of the display panel 2 consistent. The second lamp body 3212 with other deeper colors is placed in the light collecting groove 13, which can highlight the brightness of the second lamp body 3212, so that when the second lamp body 3212 in a certain light emitting assembly 32 irradiates the corresponding silk screen to develop color, it will not interfere with the display of white color of other silk screens.

[0077] Of course, the colors of the first lamp body 3211 and the second lamp body 3212 are not limited to the above examples, and can also be green, blue, yellow, etc.

[0078] In an optional embodiment, as shown in Figure 3As shown in the figure, the display device further comprises a power supply module 5 connected with the control component 31, the sensing component and the state indicator light group 321, the power supply module 5 is installed on the base 1, the control component 31, the sensing component and the state indicator light group 321 constitute the control panel 3, and the power supply module 5 can supply power for the control panel 3.

[0079] The power supply module 5 can use an adapter or a rechargeable battery / dry battery, and the type is not fixed.

[0080] When the power supply module 5 uses a rechargeable battery, a charging port connected with the power supply module is arranged on the base 1.

[0081] In addition, the power supply module 5 can be arranged on the control panel 3 or spaced apart from the control panel 3.

[0082] In an optional embodiment, as shown in the figure, Figure 1 The display device further comprises an adsorption component 6 installed on the base 1, and the adsorption component 6 is used for adsorbing the base 1 on a support, so as to facilitate users of different heights to operate the kitchen electrical equipment.

[0083] The adsorption component 6 can comprise a plurality of magnetic adsorption pieces, and the adsorption of the base 1 and the support is realized through magnetic force. The adsorption component 6 can also comprise a plurality of suction cups, and the adsorption of the base 1 on the support is realized through atmospheric pressure. That is to say, any structure that can adsorb the base 1 on the support can be the adsorption component 6 mentioned in the above embodiments.

[0084] In an optional embodiment, when the display panel 2 is inserted into the base 1 from the top surface of the base 1, as shown in the figure, Figure 1 The adsorption component 6 can have a first magnetic adsorption surface 61 and a second magnetic adsorption surface 62 for adsorbing the support, the first magnetic adsorption surface 61 is arranged to face the bottom surface of the base 1, and the second magnetic adsorption surface 62 is arranged to face the side surface of the base 1.

[0085] The above arrangement can make the base 1 not only adsorbed on the support from the bottom surface, but also adsorbed on the support from the side surface. The position of the base 1 is more flexible, and the problem that the base 1 must be placed on the support under the action of gravity is solved, and the display device is placed more humanized.

[0086] Taking the adsorption component 6 comprising a plurality of magnetic adsorption pieces as an example, as shown in the figure, Figure 1 Each magnetic adsorption piece can penetrate the front side surface and the back side surface of the base 1.

[0087] Specifically, the magnetic adsorption piece can be a magnet.

[0088] Multiple magnetic components include a first magnetic component 63 and a second magnetic component 64. Both the first magnetic component 63 and the second magnetic component 64 extend through the front side and the back side. The first magnetic component 63 has a first magnetic surface 61, and the second magnetic component 64 has a second magnetic surface 62.

[0089] In the above embodiments, the first magnetic surface 61 and the second magnetic surface 62 are respectively arranged on two magnetic components. Compared with setting them on a single magnetic component, it is not necessary to design the single magnetic component to be too thick, which can reduce the weight of the display device to a certain extent.

[0090] The first magnetic component 63 can be configured as one, two, three or more, and the second magnetic component 64 can be configured as one, two, three or more.

[0091] by Figure 1 For example, several through slots are opened on the base 1, which pass through the front side and the back side. Six magnetic components are installed in the through slots, including four first magnetic components 63 and two second magnetic components 64. One second magnetic component 64 is placed near the left side of the base 1, and the other second magnetic component 64 is placed near the right side of the base 1. The four first magnetic components 63 are located between the two first magnetic components 63 and are set near the bottom surface of the base 1.

[0092] The aforementioned slotting method facilitates the installation, disassembly, and replacement of each magnetic component, allowing the display device to be attached to the support not only by adhering to the bottom surface but also by adhering to the side surface.

[0093] Of course, the display device can also be equipped with a second magnetic 64 on one side, which can reduce the weight of the display device and reduce its cost.

[0094] Of course, in other embodiments, each magnetic component can also penetrate through the left and right sides of the base 1, or each magnetic component can be embedded in the base 1. The base 1 adopts a split structure, that is, the setting position of each magnetic component is not fixed, and any arrangement that can attract the base 1 to the support is acceptable.

[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
