Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] At present, users generally operate kitchen appliances through the display operation control modules (button circuit boards, knobs, touch panels, etc.) on the kitchen appliances, and the display operation control modules are embedded in their respective products. Due to various factors such as cost and equipment volume, the display operation control modules are generally designed to be relatively small in design and cannot be replaced or upgraded with touch screens, etc. Kitchen appliances such as range hoods, steam ovens, ovens, integrated cooktops, etc. have heaters inside, causing the temperature of the display operation control modules, etc. to be too high, and the lifespan and reliability of components to be greatly reduced. The display operation control modules of current devices are all integrated on the devices. Since the heights of operators vary, it is inconvenient to operate the same device. For example, tall users need to bend down; short users need a stool for assistance, which is extremely unsafe when operating the device. Currently, there is no low-cost, movable and independently controllable and displayable center to connect all kitchen appliances and control all the connected kitchen appliances simultaneously through the center.

[0027] Based on this, a control method and a central control screen provided by an embodiment of the present invention enable users to remotely operate kitchen appliances through the central control screen, which is more convenient and safe; using the central control screen to replace the display operation control module of the kitchen appliance greatly reduces the equipment cost and improves the lifespan and reliability of the control module; the central control screen can display different silk screens on the front or back of the glass panel and supports double-sided touch operations on the front or back.

[0028] To facilitate the understanding of this embodiment, a control method of a central control screen disclosed by an embodiment of the present invention will be introduced in detail first.

[0029] Embodiment 1:

[0030] An embodiment of the present invention provides a control method of a central control screen, which is applied to the central control screen. Refer to Figure 1 the module schematic diagram of a central control screen shown. The central control screen 100 includes: a system control board 12 and a glass panel 1. The system control board 12 includes: an infrared sensing module 18, a processing module 13, a wireless transmission module 14, and a status indicator light 16.

[0031] First, each module of the central control screen in this embodiment will be introduced:

[0032] (1) Processing module: The processing module in this embodiment can be an MCU (Microcontroller Unit, micro control unit).

[0033] (2) Glass panel: When the glass panel leaves the factory, the same pattern is printed on both sides with different inks. When the status indicator module is not working (no light shines on the glass panel), the inks on the glass panel are transparent and no pattern is displayed. Among them, different inks will develop only under the irradiation of different colored lights. After printing different inks on the glass panel, different printed contents can be displayed under the irradiation of different colored lights.

[0034] (3) Status indicator: Status indicators are provided on both the front and back of the central control screen in this embodiment. The status indicators can be set in groups, with 2 in each group.

[0035] In some embodiments, the status indicators on the front and the back display different colors.

[0036] For example: Each group of status indicators on the back can be a green LED (Lighting Emitting Diode) with a slightly higher power and a green LED with a lower power respectively (the power can determine the brightness of the light); each group of status indicators on the front can be a blue LED with a slightly higher power and a blue LED with a lower power respectively. Among them, the color of the LED can be determined according to requirements, and it is not necessary to use blue and green. As long as it can illuminate the corresponding ink screen printing function.

[0037] Based on the above description, refer to Figure 2 the flowchart of a control method for a central control screen shown in the figure. The control method for the central control screen includes the following steps:

[0038] Step S202, the system control board generates a trigger signal based on the user operation, and the processing module determines that the central control screen enters the infrared trigger working mode of the target surface based on the trigger signal; where the target surface is the front or the back.

[0039] The user can operate the system control board, the system control board generates a trigger signal, and the processing module can determine that the central control screen enters the infrared trigger working mode of the front or the back based on the trigger signal.

[0040] In some embodiments, power-on keys are provided on both the front and the back of the above system control board; the system control board generates a first trigger signal based on the operation of the user pressing the power-on key on the front, and the processing module determines that the central control screen enters the infrared trigger working mode of the front based on the first trigger signal; or, the system control board generates a second trigger signal based on the operation of the user pressing the power-on key on the back, and the processing module determines that the central control screen enters the infrared trigger working mode of the back based on the second trigger signal.

[0041] In this embodiment, a central control screen with 6 groups of button functions is taken as an example. After the central control screen is powered on, there are 6 groups of buttons on both the front and back of the central control screen. At the same time, the power-on button can be set on both the front and back. When the user presses the power-on button on the front, the system control board generates a first trigger signal, and the central control screen enters the infrared trigger working mode on the front; when the user presses the power-on button on the back, the system control board generates a second trigger signal, and the central control screen enters the infrared trigger working mode on the back.

[0042] Among them, before the user presses the power-on button on the front or back, the central control screen is in the standby state.

[0043] That is to say, the user can press the power-on button on the front or back to make the central control screen enter the working state from the standby state. Among them, the standby state in this embodiment can also be a low-power mode, an energy-saving mode, etc.

[0044] For example, after the central control screen enters the standby state, the processing module constantly checks whether the power-on button on the front or back is pressed, that is, whether there is a trigger signal. If there is a trigger signal, it enters the next step; if there is no trigger signal, it continues to be in the standby state. If the trigger signal is the first trigger signal generated by pressing the power-on button on the front, the central control screen enters the infrared trigger working mode on the front. If the trigger signal is the second trigger signal generated by pressing the power-on button on the back, the central control screen enters the infrared trigger working mode on the back.

[0045] Step S204, the processing module lights up the status indicator on the target surface to illuminate the target surface of the glass panel, and the processing module disables the status indicator on the non-target surface; among them, the content printed on the front of the glass panel is the same as the content printed on the back of the glass panel; the button positions on the front of the glass panel and the button positions on the back of the glass panel are mirror-symmetrically set with the central plane of the glass panel as the mirror.

[0046] In this embodiment, the target surface is taken as the front for illustration. After entering the infrared trigger working mode on the front, the status indicator on the front can be lit up to illuminate the front of the glass panel.

[0047] Among them, the status indicator at this time is lit based on the first power (i.e., low power), and the status indicator on the front lit by the first power can illuminate the silk screen on the front of the glass panel with the first brightness (i.e., low brightness).

[0048] And, the processing module can also disable the status indicator on the non-target surface. If the target surface is the front, the non-target surface is the back. Therefore, in this embodiment, while lighting up the status indicator on the front, the status indicator on the back can be disabled to prevent the status indicator on the back from being lit and interfering with the user.

[0049] For example, all the medium and low power blue LED lights of the front status indicator can be fully lit, and through the blue light, the user can see the front functional silk screen on the glass panel (the back does not show, and the silk screen brightness is weak).

[0050] See Figure 3 The schematic diagrams of the front and back of a glass panel shown. As Figure 3 shown, when the same content is printed on both the front and back, the mirror position of the button corresponding to Function 1 on the front (with the center plane of the glass panel as the mirror) corresponds to the button corresponding to Function 3 on the back. Therefore, the Function 1 button is always the first one when looking directly at the panel from left to right, which conforms to the user's operation logic, thus realizing the double-sided touch operation on the front or back of the central control screen.

[0051] In some embodiments, the processing module controls the status indicator of the target surface to be lit based on a first power, and the status indicator of the target surface lit by the first power illuminates the target surface of the glass panel to a first brightness; the infrared sensing module of the target surface generates a touch signal based on a user operation, and the processing module controls the status indicator corresponding to the touch signal of the target surface to be lit based on a second power, and the status indicator corresponding to the touch signal of the target surface lit by the second power illuminates the target surface of the glass panel to a second brightness; wherein, the second power is greater than the first power, and the second brightness is greater than the first brightness

[0052] Among them, the status indicator of the target surface lit by the first power can illuminate the silk screen on the target surface of the glass panel to a first brightness. The status indicator corresponding to the touch signal of the target surface lit by the second power can illuminate the silk screen corresponding to the touch signal on the target surface of the glass panel to a second brightness.

[0053] As Figure 1 shown, User 19 can touch the infrared sensing module 18 on the front according to the function shown by the silk screen on the glass panel 1 he / she sees, and the infrared sensing module 18 generates a touch signal based on the touch operation of User 19.

[0054] In some embodiments, multiple infrared emission lamps and multiple infrared reception lamps are provided on both the front and back of the system control board, and the infrared emission lamps and infrared reception lamps on the target surface generate a touch signal based on a user's touch operation.

[0055] In this embodiment, multiple infrared emission lamps and multiple infrared reception lamps can be provided on both the front and back of the system control board. The infrared emission lamps and the infrared reception lamps are in a one-to-one correspondence relationship, and a set of an infrared emission lamp and an infrared reception lamp can be used as an infrared sensing module. For example, 6 infrared sensing modules can be provided on both the front and back, and each infrared sensing module includes 1 infrared emission lamp and 1 infrared reception lamp. Therefore, a total of 12 infrared sensing modules, 12 infrared emission lamps, and 12 infrared reception lamps are provided on the system control board.

[0056] The user can touch a set of an infrared emission lamp and an infrared reception lamp, and the corresponding infrared sensing module (referred to as infrared sensing module X at this time) can generate a touch signal based on the user's touch operation. At this time, the status indicator X of the infrared sensing module X can be lit. Among them, the status indicator X at this time is lit based on the second power (i.e., the larger power), and the status indicator X lit by the second power can illuminate the silk screen X on the front of the glass panel to the second brightness (i.e., the larger brightness).

[0057] That is to say, among the status indicators at this time, the status indicators on the back are not lit, and among the status indicators on the front, the status indicator X is lit with the second power (i.e., the larger power), and the other status indicators are lit with the first power (i.e., the smaller power). In the glass panel at this time, the silk screens on the back are not lit, the silk screen X on the front is lit with the second brightness (i.e., the larger brightness), and the other silk screens on the front are lit with the first brightness (i.e., the smaller brightness). The silk screen X lit with the second brightness (i.e., the larger brightness) can prompt the user that the function indicated by the silk screen is running.

[0058] In some embodiments, the processing module sends a control signal to an external kitchen appliance based on the wireless transmission module, so that the kitchen appliance performs an operation corresponding to the touch signal based on the control signal.

[0059] As Figure 1 shown, the processing module 13 can send a control signal to the external kitchen appliance 15 based on the wireless transmission module 14, and the kitchen appliance 15 performs an operation corresponding to the touch signal based on the control signal.

[0060] Therefore, the processing module can not only drive the corresponding kitchen appliance to run the function corresponding to the touch signal, but also drive the silk screen corresponding to the touch signal to be lit with the second brightness (i.e., the larger brightness), thereby indicating to the user the function that the kitchen appliance is currently running.

[0061] In some embodiments, the infrared sensing module on the non-target surface generates a touch signal based on the user's operation, and the processing module controls the status indicator on the non-target surface to be lit based on the first power, and the status indicator on the non-target surface lit by the first power illuminates the silk screen on the non-target surface of the glass panel to the first brightness.

[0062] That is, if the target surface is the front (or back) surface, when the user presses the infrared induction module on the back (or front) surface, the status indicator light on the front (or back) surface stops working, and the status indicator light on the back (or front) surface starts working, and the function of the corresponding button is executed.

[0063] In this embodiment, the central control screen can combine the status indicator light with the glass panel for display. Compared with the existing kitchen appliance control touch panel, it is more concise in appearance, and more information can be displayed on the glass panel, which is more magnificent and more suitable for night operation.

[0064] Existing kitchen appliances generally use mechanical switch buttons for control. During use, there is mechanical stress fatigue loss and the service life is low. In this embodiment, infrared induction modules are used for control. The user does not directly contact the infrared induction module, and the module has no deformation, so the service life is greatly improved; the installation is simple, and there is no need to weld and fix like mechanical switch buttons or use corresponding structures to clamp and fix. The structural design is simple, the cost is low, and the operability in appearance design is greater.

[0065] In addition, status indicator lights are provided on both the front and back of the central control screen in this embodiment, and silk screens are provided on both the front and back of the glass panel, supporting double-sided touch operations on the front and back, and the images seen directly from the front and back are the same, which is more in line with the user's operation logic.

[0066] It should be noted that the above method provided in this embodiment can also be applied to multiple groups of LED lights to achieve single-sided multi-interface display, which will not be elaborated in this embodiment.

[0067] The embodiment of the present invention provides a control method for a central control screen. The user remotely operates the kitchen appliance through the central control screen, which is more convenient and safe; using the central control screen to replace the display operation control module of the kitchen appliance greatly reduces the equipment cost and improves the life and reliability of the control module; the central control screen can display different silk screens on the front or back of the glass panel, supporting double-sided touch operations on the front or back.
