For example, the Chinese invention patent "A Multifunctional Range Hood Control Circuit" with publication number CN112099417A (application number 202011128710.4) discloses a multifunctional function control circuit, which adopts a design of multiple control buttons, multiple drive units and switch units. Each switch unit can independently control each independent actuator of the range hood, and each control button is matched with one or more drive units, so that one button corresponds to one functional mode, so that the range hood can have multiple functional modes for users to choose, meeting the different usage needs of users. However, one control button can only correspond to one functional mode. If the product used has a richer functional mode, such as a product such as a steaming and baking micro-integrated machine, there are multiple functional modes in each cooking working mode, and the number of functional modes is large. If the aforementioned control circuit is used, the number of buttons that need to be set is too large, and the setting on a small area panel cannot be guaranteed.

[0028] Figure 1 It is a structural block diagram of the display operating system of the multifunctional cooking machine in an embodiment of the present invention.

[0029] Figure 2 It is an exploded view of the display operation panel of the multi-function cooking machine in an embodiment of the present invention.

[0030] Figure 3 It is a top view of the display operation panel of the multi-function cooking machine in an embodiment of the present invention. DETAILED DESCRIPTION

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] The multifunctional display operating system in this embodiment can be applied to various products that require multifunctional display and operation, such as cooking machines such as steam-bake all-in-one machines, rice cookers, and food processors, and can also be applied to multifunctional smart products such as refrigerators and washing machines.

[0033] like Figure 1 As shown, the multifunctional display operating system in this embodiment includes a first button group 1, a second button group 2, a working mode light group 3, a control circuit board 4, and an information display light group 5.

[0034] The first button group 1 includes at least one first button, which can be used to select and confirm the working mode and adjust the working parameters. For example, the first buttons such as "+", "-", and "Confirm / Cancel" are set. When the "+" key is operated, the selection operation of a working mode can be realized, and the increase setting operation of the parameters under the determined working mode can also be performed. When the "-" key is operated, the selection operation of another working mode can be realized, and the decrease setting operation of the parameters under the determined working mode can also be performed. The "Confirm / Cancel" key can confirm or cancel the working mode and the parameter by pressing the key for a certain period of time.

[0035] In order to improve the aesthetics of each first button, a light strip with a fixed display color may be provided on the periphery of each first button. For example, a white light strip may be selected. When a first button is operated, the corresponding display light strip is lit.

[0036] The second button group 2 includes at least one second button, and the second button group 2 is used to confirm the selection operation of the function mode under the working mode. Usually, the number of second buttons matches the maximum number of functions under one working mode. Of course, if the number of functions under one working mode is too many, the functions under the working mode can be distributed to two working modes. For example, for a steam-bake machine, if the number of functions under the steaming working mode is 4, and the number of functions under the baking working mode is 8, then 4 second buttons can be set to divide the functions under the baking working mode into two groups, and then set the first baking working mode and the second baking working mode, so that the functions under the two groups of baking working modes can cover all the functions under the baking working mode.

[0037] Each first button in the first button group 1 and each second button in the second button group 2 can be selected to use various existing touch keys, such as PCB copper foil capacitive touch sensing detection keys. When working, the operation signal of each button is obtained by obtaining the capacitance change.

[0038] The working mode light group 3 includes function display lights corresponding to each second button. According to people's viewing habits, the function display lights corresponding to each second button can be set on the left side, right side, upper side or lower side of the second button. Each function display light is an LED light with at least two color display circuits. For example, a two-color LED light can be used to display three colors. A function display light has a red LED light that can emit red light and a blue LED light that can emit blue light. When only the red LED light in the function display light is lit, the function display light displays red. When only the blue LED light in the function display light is lit, the function display light displays blue. When the red LED light and the blue LED light in the function display light are lit at the same time, the function display light displays purple. The display color of the function display light is controlled by the control circuit board 4. The function display light uses different colors to display different working modes of the product, and uses the display structure to display the text corresponding to the function in different working modes.

[0039] The information display light group 5 is used for information display. The information display light group 5 includes an information display light for displaying at least one kind of information. The information display light includes a monochrome LED light spliced ​​into a display information pattern. For example, during the operation of the product, information such as time, temperature, and humidity will be displayed. For each parameter information that needs to be displayed, an information display light is set. For example, the information display light can be set to two "8"-shaped structures spliced ​​by multiple monochrome LED lights, so that the corresponding information can be displayed. The form of the information display light is set according to specific needs. For example, for a steam-bake machine, the information display lights can be arranged and spliced ​​into words such as "Please add water", "Preheating", and "Heating". In this way, according to the working status of the steam-bake machine, the control circuit board 4 controls the information display light of the corresponding words to display.

[0040] The control circuit board 4 is electrically connected to the first button group 1, the second button group 2, the working mode light group 3, and the information display light group 5, respectively, and is used to control the function display lights in the working mode light group 3 to display the color and function mode content corresponding to the confirmed working mode according to the operation signal of the first button group 1, and then drive the execution component 7 corresponding to the selected function mode to work according to the operation signal of the second button group 2.

[0041] The control circuit board 4 is provided with: a controller 41, which is electrically connected to the execution component 7 through the load driving unit 6; a key driving chip 42, which is electrically connected to the controller 41, each first key in the first key group 1, and each second key in the second key group 2, for scanning and obtaining the operation signal of each first key and the operation signal of each second key; a function driving chip 43, which is electrically connected to the controller 41 and each function display light, and drives each function display light to work according to the control command of the controller 41; an information display driving chip 44, which is electrically connected to the controller 41 and each information display light.

[0042] like Figure 2 and Figure 3As shown, in order to facilitate direct installation and use on the product, the first button group 1, the second button group 2, the working mode light group 3, the information display light group 5, and the control circuit board 4 are arranged in a board body 100 to form a multifunctional display operation panel, and the first button group 1, the second button group 2, and the working mode light group 3 are connected to the control circuit board 4. The board body 100 includes a board frame 101, a light-transmitting film 102, and a light-transmitting panel 103, and the control circuit board 4 is matched and installed below the board frame 101. The board frame 101 is provided with an opening 1011 corresponding to each first button in the first button group 1, the second button in the second button group 2, each function display light in the working mode light group 3, and each information display light in the information display light group 5. Each first button and second button are embedded in the opening 1011 to facilitate the acquisition of the user's touch information. And each function display light and information display light can transmit light through the opening 1011. The light-transmitting panel 103 is matched and arranged above the plate frame 101. The light-transmitting panel 103 can be a glass panel. In order to improve the display effect, a light-transmitting film can be attached to the glass panel. The light-transmitting film 102 is sandwiched between the plate frame 101 and the light-transmitting panel 103. The light-transmitting film 102 in this embodiment includes at least two layers of film layers stacked for different colors of light in the function display lamp to pass through. As mentioned above, when the function display lamp used is a two-color LED lamp, the two-color LED lamp can realize three-color display. The corresponding light-transmitting film 102 includes a red light film layer that can transmit red light, a blue light film layer that can transmit blue light, and a purple light film layer that can transmit purple light. In order to protect the light-transmitting film 102, a white light film layer is also arranged on the top. In order to facilitate the display of functional information, on different film layers, the light-transmitting area of ​​the corresponding functional text / icon is set only at the position corresponding to the function display on the second button, so that for the same second button, different colors and different functional text / icons can be displayed.

[0043] For example, for a steam-bake machine, in the steaming mode, only the red light in the two-color LED light is on, and different second buttons will display red function words such as "normal steaming", "over-temperature steaming", "fermentation", "thawing", and "steam cleaning". In the baking mode, only the blue light in the two-color LED light is on, and different second buttons will display function words such as "full-open baking", "humidified baking", "grilling", "tappetizer", and "upper and lower fire baking". In the auxiliary mode, the red and blue lights in the two-color LED light are on at the same time, and different second buttons will display purple function words such as "confirmation", "drying", "descaling", "lighting", and "screen lock". The user operates the second button according to the prompts of these function words, and then the controller 41 controls the load drive unit 6 to drive the corresponding function execution component 7 to work after obtaining the operation signal of the second button.

[0044] In this embodiment, the first button and the second button are both PCB copper foil capacitive touch sensing detection buttons, and the user can select the first button and the second button by touching the button. When working, the operation signal of the first button and the second button is obtained by detecting the capacitance change of the first button and the second button.

[0045] In addition to the first button and the second button, in order to facilitate the on / off control of the multifunctional display operating system, a power button electrically connected to the control circuit board 4 and the power supply circuit can be specially provided, and the user can turn on and off the multifunctional display operating system by operating the power button. The power button can be the on / off button of the product using the multifunctional display operating system.

[0046] The multi-function display operation method in the present invention is: corresponding to different working modes, the control circuit board 4 can control the working mode light group 3 to display different colors. After the product is powered on, the user operates the first button in the first button group 1, and the control circuit board 4 determines the working mode selection and confirmation information according to the operation signal of the first button. At the same time, the control circuit board 4 controls each function display light in the working mode light group 3 to display the display color corresponding to the real-time working mode information. After the working mode is confirmed, the user operates the first button in the first button group 1 to adjust the working parameters under the working mode; and / or the user operates the second button in the second button group 2 to select the function under the working mode.

[0047] The aforementioned multifunctional display operating system can be applied in a cooking machine used for cooking food and display operation can be performed according to the aforementioned multifunctional display operating method.

[0048] The multifunctional display operating system in the present invention, using the multifunctional display operating method in the present invention, can characterize and display different working modes of the product through the change of different display colors, so that one button is used to reuse the functional mode operation mode under different working modes to drive the execution component 7 corresponding to each functional mode under different working modes to work, so that the control work of multiple functional modes of different working modes can be realized through fewer operation buttons, which is low in cost, conducive to the expansion of multi-functions, and the user operation is clearer and more convenient. In addition, the color will change during the display process, which also increases the aesthetics and interest, and can enhance the user experience.
