[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0022] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0023] See also Figure 1 , is a circuit connection diagram of a knob provided in an embodiment of the present invention. The knob includes a main body, a control module and a rotary encoding module are arranged in the main body, and N (N is an integer equal to or greater than 4) touch sensors are arranged on the surface of the main body around its rotation axis, and the rotary encoding module and each touch sensor are electrically connected to the control module. The touch sensor can be a capacitive, resistive, pressure-sensitive, grating or other sensor, and each touch sensor has a sensing area. For ease of understanding, an embodiment of the present invention provides an example diagram of the appearance of a knob, please refer to Figure 2 , where the surface of the knob is divided into N sensing areas of equal area.

[0024] Among them, the rotation encoding module is used to generate a corresponding adjustment signal according to the collected rotation angle. The touch sensor is used to generate a corresponding touch signal according to the touch state detected by its sensing area. The control module is used to determine the corresponding adjustment mode according to the touch signal, and determine the adjustment result to be output according to the adjustment mode and the adjustment signal, and the adjustment result is a first result corresponding to the first mode, or a second result corresponding to the second mode. The first mode corresponds to a single sensing area being triggered or multiple continuous sensing areas being triggered; the second mode corresponds to at least two sensing areas being triggered, and the at least two sensing areas are spaced apart.

[0025] In this embodiment, when the user performs an adjustment operation on the knob, the rotary encoding module will collect the angle at which the user rotates the knob to obtain the rotation angle, and generate a corresponding adjustment signal according to the rotation angle and transmit it to the control module, for example, the number of electronic pulses is calculated according to the rotation angle and transmitted to the control module. At the same time, each touch sensor will detect whether the user's finger touches its sensing area, and generate a corresponding touch signal according to the touch state detected by its sensing area and transmit it to the control module.

[0026] It is understandable that when the user uses the knob to adjust, there are two different adjustment requirements: fine adjustment and coarse adjustment. When the user rotates the knob, he can use a single-finger dialing control method or a multi-finger twisting control method. The embodiment of the present invention sets two modes based on these two different control methods to represent different adjustment fineness or to represent different adjustment objects. Then the control module can determine the control method used by the user according to the touch state of each sensing area represented by each touch signal, thereby determining the current adjustment mode.

[0027] In the embodiment of the present invention, the mode corresponding to the single-finger flicking control mode is set as the first mode, and the mode corresponding to the multi-finger twisting control mode is set as the second mode. The following description will be based on these two modes.

[0028] When only a single sensing area is triggered, it means that the user only uses one finger to operate the knob, and the knob surface touched by this finger is the same sensing area, that is, the user uses a single-finger dialing control method, and the current adjustment mode is determined to be the first mode. Figure 3 As shown, the user only uses one finger to operate the knob, and the finger touches the first sensing area on the knob surface, that is, only a single sensing area is triggered, indicating that the user uses a single-finger dialing control method, and the current adjustment mode is determined to be the first mode.

[0029] When multiple continuous sensing areas are triggered, it means that the user uses only one finger to manipulate the knob, and the knob surface touched by this finger is multiple continuous sensing areas, that is, the user uses a single-finger manipulation method, and the current adjustment mode is determined to be the first mode. Figure 4 As shown, the user only uses one finger to operate the knob, and the finger touches the first sensing area and the second sensing area on the knob surface, that is, two consecutive sensing areas are triggered, indicating that the user uses a single-finger dialing control method, and the current adjustment mode is determined to be the first mode.

[0030] When at least two spaced sensing areas are triggered, it means that the user uses at least two fingers to operate the knob, and these fingers touch the spaced sensing areas on the knob surface, that is, the user uses a multi-finger twisting control method, and the current mode is determined to be the second mode. Figure 5 As shown, the user uses two fingers to operate the knob, and one of the fingers touches the first sensing area on the knob surface, and the other finger touches the N / 2+1th sensing area on the knob surface, that is, two spaced sensing areas are triggered, indicating that the user uses a multi-finger twisting control method, and the current mode is determined to be the second mode.

[0031] After the control module determines the adjustment mode, it will also determine the adjustment result in combination with the adjustment signal. When the adjustment mode is the first mode, the control module determines the adjustment result as the first result based on the first mode and the adjustment signal. When the adjustment mode is the second mode, the control module determines the adjustment result as the second result based on the second mode and the adjustment signal.

[0032] It can be understood that the knob in the embodiment of the present invention uses a control module to obtain the touch state of each sensing area on the knob surface according to the touch signal generated by each touch sensor, so as to determine the user's way of operating the knob and obtain the corresponding adjustment mode, and determine the corresponding adjustment result in combination with the adjustment signal output by the rotary encoding module. Thus, the user can operate the knob in two different ways, single finger and multi-finger, so that the knob uses different adjustment modes according to different operation methods to output different adjustment results.

[0033] Optionally, the knob may also be electrically connected to the indicator light. For ease of understanding, the present invention provides a schematic diagram of the circuit connection between the knob and the indicator light. Figure 6 Accordingly, the embodiment of the present invention also provides an example diagram of a knob electrically connected to an indicator light, see Figure 7 .

[0034] It should be noted that the indicator light can also be set in the knob and electrically connected to the control module. Accordingly, the present invention also provides a circuit connection diagram of the knob, see Figure 8 Accordingly, the embodiment of the present invention also provides a circuit connection diagram of a knob provided with an indicator light, please refer to Fig. 9 , where the shaded area represents an indicator light, and the indicator light serves as the backlight of the knob.

[0035] It is understandable that the indicator light can be implemented by a current limiting resistor and a light emitting diode. And whether the indicator light is set in the knob or not, it can be used to indicate the current adjustment mode corresponding to the knob. Then the user can know the current adjustment mode corresponding to the knob according to the current state of the indicator light. For ease of understanding, the embodiment of the present invention takes the knob on the steam oven as an example, provides two example diagrams of the steam oven with knobs, and based on the above two indicator light setting methods, respectively explains the way in which the indicator light indicates the adjustment mode of the knob.

[0036] See also Fig.10 The knob on the steam oven is electrically connected to an indicator light. Fig.10 (1) The indicator light shown is not on, which means that the current adjustment mode corresponding to the knob is the first mode; Fig.10 The indicator light (2) is on, indicating that the current adjustment mode of the knob is the second mode. Fig.11 The knob on the steam oven is equipped with an indicator light. Fig.11 (1) The indicator light shown is not on, which means that the current adjustment mode corresponding to the knob is the first mode; Fig.11 The indicator light shown in (2) is on, indicating that the current adjustment mode corresponding to the knob is the second mode.

[0037] It should be understood that the color of the indicator light can also be used to indicate the current corresponding adjustment mode of the knob. That is, the state of the indicator light can be set according to actual conditions to indicate different modes of the knob, and the embodiment of the present invention is not limited to this.

[0038] Optionally, based on the above two methods for representing different degrees of adjustment precision, an embodiment of the present invention provides a corresponding implementation method, namely: the first result amplifies the adjustment amplitude corresponding to the adjustment signal under the corresponding adjustment item compared to the second result. And the adjustment item is one of the following four items: (A1) parameter adjustment item, used to numerically adjust the corresponding parameter; (A2) function adjustment item, used to switch between at least two functions; (A3) menu adjustment item, used to switch between at least two menus; (A4) interface adjustment item, used to flip between different display areas of the interactive interface.

[0039] To facilitate understanding, these four items are explained below using the knobs on a steam oven as an example.

[0040] The first type of project: when the adjustment project is a parameter adjustment project, the first result, compared with the second result, amplifies the parameter change value corresponding to the adjustment signal under the parameter adjustment project.

[0041] For example, take the parameter adjustment item of adjusting the grilling temperature of the steam oven as an example, and the first step length corresponding to the first mode is the first temperature adjustment step length such as 5°C, and the second step length corresponding to the second mode is the second temperature adjustment step length such as 1°C.

[0042] Assuming that the adjustment signal is -1, the first result corresponding to the first mode is: the product of the first temperature adjustment step of 5°C and the adjustment signal -1 is -5°C, so the grilling temperature of the steam oven is adjusted from the current 185°C to 180°C. Fig.12 The second result corresponding to the second mode is: the product of the second temperature adjustment step 1°C and the adjustment signal -1 is -1°C, so the grilling temperature of the steam oven is adjusted from the current 185°C to 184°C. Fig.13As shown. It can be understood that, since the temperature adjustment step length corresponding to the first mode is greater than the temperature adjustment step length corresponding to the second mode, the first result corresponding to the first mode (i.e., the barbecue temperature changes by 5°C) is greater than the second result corresponding to the second mode (i.e., the barbecue temperature changes by 1°C). That is, compared with the second result, the first result amplifies the parameter change value corresponding to the adjustment signal under the parameter adjustment item of adjusting the barbecue temperature of the steam oven.

[0043] The second type of project: when the adjustment project is a function adjustment project, the first result, compared with the second result, amplifies the number of function switches corresponding to the adjustment signal under the function adjustment project.

[0044] For example, taking the function adjustment item of adjusting the cooking function of the steam oven as an example, the cooking functions include steaming, baking, frying, and microwaving; and the first step length corresponding to the first mode is the first function adjustment step length such as 3, and the second step length corresponding to the second mode is the second function adjustment step length such as 1.

[0045] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the product of the first function adjustment step 3 and the adjustment signal 1 is +3, and the cooking function of the steam oven is switched from the current steam to micro. Fig.14 The second result corresponding to the second mode is: the product of the second function adjustment step 1 and the adjustment signal +1 is +1, which means the cooking function of the steam oven is switched from the current steaming to baking. Fig.15 As shown. It can be understood that, since the function adjustment step length corresponding to the first mode is greater than the function adjustment step length corresponding to the second mode, the first result corresponding to the first mode (i.e., 3 cooking functions are switched) is greater than the second result corresponding to the second mode (i.e., 1 cooking function is switched). That is, compared with the second result, the first result amplifies the number of function switches corresponding to the adjustment signal under the function adjustment item of adjusting the cooking function of the steam oven.

[0046] The third item: when the adjustment item is a menu adjustment item, the first result, compared with the second result, amplifies the number of menu switches corresponding to the adjustment signal under the menu adjustment item.

[0047] For example, taking the menu adjustment item of adjusting the cooking menu of the steam oven as an example, the cooking menu includes toasting, thawing meat, and hot milk; and the first step length corresponding to the first mode is the first menu adjustment step length such as 2, and the second step length corresponding to the second mode is the second menu adjustment step length such as 1.

[0048] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the product of the first function adjustment step 2 and the adjustment signal +1 is +2, then the cooking menu of the steam oven key is switched from toast to hot milk, such as Fig.16The second result corresponding to the second mode is: the product of the second function adjustment step +1 and the adjustment signal +1 is +1, then the cooking menu of the steam oven key is switched from toast to thawed meat, such as Fig.17 As shown. It can be understood that, since the menu adjustment step length corresponding to the first mode is greater than the menu adjustment step length corresponding to the second mode, the first result corresponding to the first mode (i.e., 2 cooking menus are switched) is greater than the second result corresponding to the second mode (i.e., 1 cooking menu is switched). That is, compared with the second result, the first result amplifies the number of menu switches corresponding to the adjustment signal under the menu adjustment item of adjusting the cooking menu of the steam oven.

[0049] The fourth type of item: when the adjustment item is an interface adjustment item, the first result, compared with the second result, amplifies the number of interface flips corresponding to the adjustment signal under the interface adjustment item.

[0050] For example, take the interface adjustment item of adjusting the recipe display interface of the steam oven as an example, and the first step length corresponding to the first mode is the first interface adjustment step length such as 4 lines, and the second step length corresponding to the second mode is the second interface adjustment step length such as 1 line.

[0051] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the product of the first interface adjustment step 4 and the adjustment signal +1 is +4 lines, and the recipe display interface of the steam oven is scrolled back 4 lines, such as Fig.18 The second result corresponding to the second mode is: the product of the second interface adjustment step 1 and the adjustment signal +1 is +1 line, then the recipe display interface of the steam oven is flipped back by 1 line, such as Fig.19 As shown. It can be understood that, since the interface adjustment step length corresponding to the first mode is greater than the interface adjustment step length corresponding to the second mode, the first result corresponding to the first mode (i.e., 4 lines of the interface have been flipped) is greater than the second result corresponding to the second mode (i.e., 1 line of the interface has been flipped). That is, compared with the second result, the first result amplifies the number of interface flips corresponding to the adjustment signal under the interface adjustment item of adjusting the recipe display interface of the steam oven.

[0052] It should be understood that the adjustment step of the first interface and the adjustment step of the second interface can also be expressed by area. For example, the area represented by the adjustment step of the first interface is a, and the area represented by the adjustment step of the second interface is b, and a is greater than b. Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the product of the adjustment step of the first interface a and the adjustment signal +1 is +a, and the area of ​​the recipe display interface of the steam oven is flipped back is a. The second result corresponding to the second mode is: the product of the adjustment step of the second interface b and the adjustment signal +1 is +b, and the area of ​​the recipe display interface of the steam oven is flipped back is b.

[0053] Optionally, based on the above two modes for representing different adjustment objects, an embodiment of the present invention provides a corresponding implementation method, namely: the first result and the second result correspond to the main item and sub-item of the corresponding adjustment item, respectively. And the adjustment item is one of the following four items: (B1) parameter adjustment item, used for numerical adjustment of main parameters and sub-parameters; (B2) function adjustment item, used for mode switching of main functions and sub-functions; (B3) menu adjustment item, used for content switching of main menus and sub-menus; (B4) interface adjustment item, used for flipping through main areas and sub-areas in an interactive interface.

[0054] To facilitate understanding, these four items are explained below using the knobs on a steam oven as an example.

[0055] The first type of project: when the adjustment project is a parameter adjustment project, the first result corresponds to the main parameter in the parameter adjustment project, and the second result corresponds to the sub-parameter in the parameter adjustment project.

[0056] For example, taking the parameter adjustment item of adjusting the grilling temperature of the steam oven as an example, the main parameter of the grilling temperature is the oven temperature and the sub-parameter is the grill temperature, and the first mode corresponds to the oven temperature and the second mode corresponds to the grill temperature.

[0057] Assuming that the adjustment signal is -5, the first result corresponding to the first mode is: the oven temperature is lowered by 5°C, and the oven temperature of the steam oven is lowered from the current 185°C to 180°C. Fig. 20 The second result corresponding to the second mode is: if the grill temperature is lowered by 5°C, the grill temperature of the steam oven is lowered from the current 200°C to 195°C. Fig.21 shown.

[0058] Second type of project: When the adjustment project is a function adjustment project, the first result corresponds to the main function in the function adjustment project, and the second result corresponds to the sub-function in the function adjustment project.

[0059] For example, if the function adjustment item is to adjust the cooking function of the steam oven, the main functions of the cooking function include steaming, baking, frying, and micro-frying. Each main function has multiple sub-functions. For example, the sub-functions of the main function of steaming include nutritious steaming, steaming, high temperature steaming, and fresh steaming; the sub-functions of the main function of baking include air baking, humidification baking, strong baking, and fan baking. And the first mode corresponds to the main function, and the second mode corresponds to the sub-function.

[0060] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the cooking main function is switched to 1, and the main cooking function of the steam oven is switched from the current steaming to baking, such as Fig. 22As shown; the second result corresponding to the second mode is: if the cooking sub-function is switched to 1, the cooking sub-function of the steam oven is switched from the current nutritional steaming to the surging steaming, such as Fig.23 shown.

[0061] The third type of item: when the adjustment item is a menu adjustment item, the first result corresponds to the main menu in the menu adjustment item, and the second result corresponds to the submenu in the menu adjustment item.

[0062] For example, taking the cooking menu of adjusting the steam oven as an example, the main menu of the cooking menu includes toast, defrost meat, and hot milk. Each main menu has multiple submenus. For example, the submenus of the toast main menu include single-slice toast, double-sided toast, and smart toast, and the submenus of the defrost meat main menu include half defrost, full defrost, and fast defrost. And the first mode corresponds to the main menu, and the second mode corresponds to the submenu.

[0063] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the cooking main menu is switched by 1, and the cooking main menu of the steam oven is switched from the current toast to thawed meat, such as Fig.24 As shown; the second result corresponding to the second mode is: if the cooking submenu is switched by 1, the steam oven cooking submenu is switched from the current single-piece baking to double-sided baking, such as Fig.25 shown.

[0064] Fourth type of item: when the adjustment item is an interface adjustment item, the first result corresponds to a main area in the interface adjustment item, and the second result corresponds to a sub-area in the interface adjustment item.

[0065] For example, taking the recipe display interface of adjusting the steam oven as an example, the recipe display interface includes a main area for displaying the ingredient list and a sub-area for displaying the production steps. The first mode corresponds to the main area, and the second mode corresponds to the sub-area.

[0066] Assuming that the adjustment signal is +1, the first result corresponding to the first mode is: the main area is flipped back by 1 line, and the main area of ​​the recipe display interface of the steam oven is flipped back by 1 line, such as Fig.26 The second result corresponding to the second mode is: the sub-area is flipped back by one line, and the sub-area of ​​the recipe display interface of the steam oven is flipped back by one line, such as Fig. 27 shown.

[0067] For ease of understanding, the present invention provides a circuit connection diagram of a knob by taking the example of a knob having four touch sensors. Fig.28 The knob includes four touch sensors, namely, touch sensor 1, touch sensor 2, touch sensor 3 and touch sensor 4.

[0068] Accordingly, based on the fact that the knob includes four touch sensors, an embodiment of the present invention further provides an example diagram of the appearance of a knob, see Fig.29 The knob is divided into four quadrants, namely quadrant 1, quadrant 2, quadrant 3 and quadrant 4, and the touch detection area of ​​one quadrant is the sensing area of ​​one touch sensor. For example, the sensing area of ​​touch sensor 1 is the touch detection area of ​​quadrant 1, the sensing area of ​​touch sensor 2 is the touch detection area of ​​quadrant 2, the sensing area of ​​touch sensor 3 is the touch detection area of ​​quadrant 3, and the sensing area of ​​touch sensor 4 is the touch detection area of ​​quadrant 4.

[0069] The following will be combined Fig.28 and Fig.29 , further introduces the functions of each device in the knob. Among them, the touch sensor is used to generate a high level when the touch state detected in its sensing area is touched, and to generate a low level when the touch state detected in its sensing area is not touched. The control module is also used to perform an AND operation on the first group of touch signals to obtain a first operation result, and to perform an AND operation on the second group of touch signals to obtain a second operation result; the first group of touch signals is two touch signals and represents the touch state of two spaced sensing areas, and the second group of touch signals is another two touch signals and represents the touch state of another two spaced sensing areas. The control module is also used to perform an OR operation on the first operation result and the second operation result to obtain a third operation result, and determine the corresponding adjustment mode according to the third operation result, wherein when the third operation result is a low level, the adjustment mode is the first mode; when the third operation result is a high level, the adjustment mode is the second mode.

[0070] For ease of understanding, the present invention provides an example of a logic circuit diagram of a control module. Fig.30 Wherein I1 represents the touch signal generated by touch sensor 1, I2 represents the touch signal generated by touch sensor 2, I3 represents the touch signal generated by touch sensor 3, I4 represents the touch signal generated by touch sensor 4, S1 represents the first operation result, S2 represents the second operation result, and S3 represents the third operation result.

[0071] When the user uses a single finger to operate the knob, the finger touches a single sensing area on the knob surface, for example, the user's finger touches the sensing area of ​​the three quadrants, then the touch signal generated by touch sensor 3 is high level, and the touch signals generated by touch sensor 1, touch sensor 2 and touch sensor 4 are all low level. Then the control module obtains the first operation result as low level, the second operation result as low level, and the third operation result as low level through logical operation, so it determines that the current adjustment mode is the first mode.

[0072] When the user uses multiple fingers to manipulate the knob, these fingers touch the spaced sensing areas on the knob surface, for example, two fingers of the user touch the sensing areas of the first and third quadrants respectively, then the touch signals generated by touch sensor 1 and touch sensor 3 are both high level, and the touch signals generated by touch sensor 2 and touch sensor 4 are both low level. Then the control module obtains the first operation result as high level, the second operation result as low level, and the third operation result as high level through logical operation, so it determines that the current adjustment mode is the second mode.

[0073] Based on the knob provided above, an embodiment of the present invention further provides a smart home appliance control method.

[0074] Step S202: obtaining an adjustment result according to the adjustment operation performed by the user on the knob, where the adjustment result is a first result or a second result.

[0075] Step S204: when the adjustment result is the first result, perform work according to the first result and / or feed back adjustment completion information to the user.

[0076] Step S206: When the adjustment result is the second result, work is performed according to the second result and / or adjustment completion information is fed back to the user.

[0077] In this embodiment, the smart home appliance obtains an adjustment result output by the knob based on the adjustment operation performed by the user on the knob. The adjustment result is a first result corresponding to the first mode, or a second result corresponding to the second mode.

[0078] When the adjustment result is the first result, it means that the user uses a single-finger manipulation method to adjust the knob, and then the operation is performed according to the first result and / or adjustment completion information is fed back to the user. That is, the operation of the smart home appliance is controlled according to the first result, and / or the adjustment completion information is fed back through sound or image to prompt the user that the adjustment is completed.

[0079] If the adjustment result is the second result, it means that the user uses a multi-finger twisting control method to adjust the knob, then the operation is performed according to the second result and / or adjustment completion information is fed back to the user. That is, the operation of the smart home appliance is controlled according to the second result, and / or the adjustment completion information is fed back through sound or image to prompt the user that the adjustment is completed.

[0080] It can be seen that based on the above steps, the embodiment of the present invention enables the user to control the knob in two different ways: single finger and multi-finger, so that the knob adopts different adjustment modes according to different operation methods to output different adjustment results, so as to control the smart home appliances to operate in different ways.
