Therefore, if there are multiple cooking devices in the kitchen, these cooking devices have their own power cords connected to the sockets. On the one hand, due to the large number of power cords, the multiple power cords are entangled with each other and occupy a large area. On the other hand, many wires require multiple sockets, and when the wires are old or damaged, safety accidents are prone to occur due to leakage. Summary of the invention

[0023] Based on the above solution, the control module is also used to control the integrated module corresponding to the load-bearing area where the load is located to be in a non-working state when the signal value of the detection signal corresponding to the load-bearing area where the load is located is between the first reference value and the second reference value.

[0024] Based on the above solution, the electrical equipment further includes:

[0025] A wireless communication module, used to establish wireless communication for wireless power transmission with a charging load receiving wireless power transmission when the integrated module enters the wireless power transmission mode;

[0026] The control module is connected to the wireless communication module, and is used to control the integrated module in the wireless power transmission mode to wirelessly transmit power to the charging load after the wireless communication module successfully establishes communication with the charging load.

[0027] A second aspect of the embodiment of the present application provides a working method of an electrical device, including:

[0028] Acquire a detection signal formed by a detection module that can be coupled with a load, wherein the detection module is used to detect whether there is a load and the type of load in a bearing area corresponding to an integrated module;

[0029] If the detection signal indicates that a load is placed in the bearing area corresponding to the integrated module in the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load.

[0030] Based on the above scheme, if the detection signal indicates that a load is placed in the bearing area corresponding to the integrated module in the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to work in a heating mode for heating the load or a wireless charging mode for charging the load, including:

[0031] Comparing the signal value of the detection signal with a reference value to obtain a comparison result;

[0032] When it is determined according to the comparison result that a load is placed in the bearing area within the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load.

[0034] Comparing the signal value of the detection signal with a first reference value and a second reference value respectively, wherein the second reference value is smaller than the first reference value;

[0035] When it is determined according to the comparison result that a load is placed in the bearing area in the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load, including:

[0036] When the detection signal is greater than the first reference value, the integrated module corresponding to the load-bearing area is controlled to enter a working state and operate in the wireless power transmission mode;

[0037] When the detection signal is less than the second reference value, the integrated module corresponding to the load-bearing area is controlled to enter a working state and operate in the heating mode.

[0038] Based on the above scheme, the method also includes:

[0039] When the signal value of the detection signal is between the first reference value and the second reference value, the integrated module corresponding to the load-bearing area where the load is located is controlled to be in a non-working state.

[0040] The technical solution provided by the embodiment of the present invention is that the electrical equipment includes multiple integrated modules that can work in heating mode and wireless power transmission mode at the same time; when the integrated module works in heating mode, the heating load can be heated; when the integrated module works in wireless power transmission mode, the charging load can be wirelessly transmitted.

[0049] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] like Figure 1 As shown, this embodiment provides an electrical device, including:

[0051] A load-bearing shell having a load-bearing surface;

[0052] A plurality of integrated modules are arranged in parallel in the bearing housing, wherein different integrated modules have different bearing areas on the bearing surface;

[0053] A plurality of detection modules are located in the bearing shell, wherein the detection modules are used to detect whether there is a load and the type of load on the bearing area and generate a detection signal;

[0054] The control module is respectively connected to the detection module and the integrated module, and is used to control the integrated module corresponding to the load-bearing area to enter a working state when it is determined that there is a load in the load-bearing area based on the detection signal, and to control the integrated module corresponding to the load-bearing area to work in a heating mode for heating the load or a wireless charging mode for charging the load based on the load type represented by the detection signal.

[0055] For example, there are I integrated modules in total. The I integrated modules are arranged in parallel in the bearing housing, and the i-th integrated module corresponds to the i-th bearing area of ​​the bearing surface; I is a positive integer not less than 2.

[0056] For another example, there are a total of I detection modules, and these I detection modules are located in the carrying shell, wherein one detection module corresponds to one integrated module; the i-th detection module is used to detect whether there is a load and the type of load in the i-th carrying area, and generate an i-th detection signal, wherein i is a positive integer less than or equal to I.

[0057] The control module can be connected to the detection module and the integrated module respectively, and is used to control the i-th integrated module to enter a working state when it is determined that there is a load in the i-th bearing area based on the i-th detection signal, and control the i-th integrated module to work in a heating mode for heating the load or a wireless charging mode for charging the load based on the load type represented by the i-th detection signal.

[0058] In this embodiment, the electrical device may include a rectangular or cylindrical carrying shell, in which a plurality of integrated modules having both heating and power supply functions are arranged.

[0059] The bearing shell has at least one surface facing upwards, which can be used to bear a load, and this surface is the bearing surface; any load can be carried on the bearing surface.

[0060] The load includes, but is not limited to, a heating load, and / or a charging load that needs to be charged.

[0061] The heating load may include: a cooking load for cooking; specifically, the cooking load includes various cooking devices. The charging load includes various powered devices capable of receiving wireless charging.

[0062] In this embodiment, the cooking equipment includes but is not limited to: an induction cooker and / or an induction cooker pot and other devices.

[0063] The powered device may be any electronic device capable of receiving a wireless charging signal. For example, the powered device includes but is not limited to a mobile phone, a tablet computer or a wearable device capable of wireless charging.

[0064] In this embodiment, a plurality of integrated modules are disposed in the carrying shell. These integrated modules may be arranged in sequence in the carrying shell. Specifically, for example, a plurality of integrated modules are distributed in a matrix in the carrying shell.

[0065] The bearing housing has a bearing surface, and the bearing surface can be used to place a load, and the load can be other load equipment or equipment that needs to be charged. The load includes the aforementioned electrical equipment and / or the powered equipment.

[0066] In this embodiment, the integrated modules all include: a working circuit; the working circuit works in the heating mode or the wireless power transmission mode under different input power consumptions.

[0067] For example, the power control of the working circuit in the integrated module is achieved by adjusting the duty cycle and / or frequency of the input signal of the integrated module.

[0068] In some cases, the integrated module operates in the heating mode of the first level power, and the integrated module generates a first power consumption. When the integrated module operates in the wireless power transmission mode, the integrated module generates a second power consumption, and the first power consumption is greater than the second power consumption. In other cases, the integrated module can also operate in the heating mode of the second level power, and the integrated module generates a third power consumption; the third power consumption is less than the second power consumption.

[0069] For example, the heating mode of the first level power can be used for cooking food; the heating device of the second level power can be used to keep the cooked food warm. At this time, although the integrated modules are all working in the heating mode, the requirements for heating power are different. In some specific cases, the power consumption generated by the heating mode of the second level power may even be less than the power consumption generated by wireless power supply to the powered device in the wireless power transmission mode.

[0070] At this time, the power control module of the electrical equipment can realize power output control of the working circuit by adjusting the signal parameters of the input signal input to the integrated module, such as frequency or duty cycle, thereby realizing control of the working mode of the integrated module.

[0071] Of course, in the specific implementation process, the first-level power heating mode, the second-level power heating mode and / or the wireless power transmission mode can also be subdivided into multiple sub-modes, and the power consumption generated by each sub-mode can be different; the specific implementation method is also achieved through the input power of the input signal, which will not be repeated here. The power of the integrated module in the heating mode and the wireless power transmission mode can be set according to specific needs.

[0072] In this embodiment, the electrical device includes the same number of detection modules as the number of integrated modules, and the detection modules can at least be used to detect whether there is a load on the bearing surface. If there is a load, the integrated module may need to switch from a non-working state to a working state.

[0073] A detection module can detect whether there is a load and the type of load in the bearing area corresponding to an integrated module. In this way, the electrical equipment itself can detect whether there is a load and the type of load, and accurately control whether the corresponding integrated module enters the working state, and the working mode after entering the working state, without the user manually controlling the operation of the integrated module in the electrical equipment, or controlling the working state and working mode of the integrated module by control signals from other devices, thereby enhancing the intelligence of the electrical equipment.

[0074] In this embodiment, when the integrated module is in a non-working state, there is no current transmission in the working circuit corresponding to the integrated module, and the integrated module itself does not generate power consumption. If the integrated module is in a working state, there is current in the working circuit of the integrated module, and the integrated module generates power consumption for heating or wireless power transmission.

[0075] In this embodiment, the electrical device includes a detection module, which can at least be used to detect whether there is a load on the bearing surface. If there is a load, the integrated module may need to switch from a non-working state to a working state.

[0076] In this embodiment, one detection module corresponds to one integrated module, and the detection modules correspond to different bearing areas of the bearing surface. In this way, the detection module can detect the position of the load through its own position.

[0077] When the integrated module is in a non-working state, there is no current transmission in the working circuit corresponding to the integrated module, and the integrated module itself does not generate power consumption. If the integrated module is in a working state, there is current in the working circuit of the integrated module, and the integrated module generates power consumption for heating or wireless power transmission.

[0078] Specifically, the control module can at least confirm whether there is a load in the bearing area of ​​the i-th integrated module based on the detection signal. If there is a load, the i-th integrated module can be controlled to be in a working state; if there is no load, the i-th integrated module can be controlled to be in a non-working state.

[0079] Here, i is any positive integer less than the total number I of integrated modules included in the electrical device.

[0080] In some embodiments, the detection module can detect whether there is a load on each integrated module and report the obtained detection signal to the control module, which can then control the current state of the corresponding integrated module, whether it is a working state or a non-working state.

[0081] The specific structure of the control module may include various devices with signal processing functions and / or control functions, such as a controller; the control module may be: a central processing unit, a microprocessor, a digital signal processor, a programmable array or an application-specific integrated circuit.

[0082] Furthermore, the detection module can also be used to detect the load type; the control module is also used to control the integrated module to operate in the heating mode or the wireless power transmission mode according to the load type.

[0083] In this embodiment, the load types include at least two types, heating load and power transmission load.

[0084] In this way, the control module can be specifically used to control the working mode of the integrated module after it enters the working state according to the load type.

[0085] For example, if the load type of the current load is a heating load, the corresponding integrated module is controlled to work in a heating mode; if the load type of the current load is a power transmission load, the corresponding integrated module is controlled to work in a wireless power transmission mode.

[0086] In some embodiments, the same detection signal of the detection module can simultaneously integrate at least whether there is a load and the type of load in the bearing area of ​​the module.

[0087] In some other embodiments, the detection module provides at least two detection signals; one detection signal is used to indicate whether there is a load in the bearing area of ​​the integrated module; and the other detection signal indicates the type of load.

[0088] In order to simplify the circuit structure and control in this embodiment, the detection signal provided by the detection module in this embodiment can simultaneously indicate whether there is a load and the type of load in the bearing area of ​​the integrated module.

[0089] For example, the detection module includes an inductive sensing element, which can generate mutual inductance with the load; in this way, when the detection module is in working state, there is current in the circuit corresponding to the detection module. If the load is placed in the load-bearing area corresponding to the detection module, the load and the sensing element in the detection module are mutually inductive, thereby causing the impedance in the detection module to change, thereby causing the electrical signal value (i.e., the working signal) in the detection module to change. In this way, the control module can know whether there is a load and / or the type of load in the current corresponding load-bearing area by sampling the working signal of the detection module.

[0090] For another example, the detection module may include: a capacitive sensing element, which forms capacitance with the load and / or changes the capacitive parameter after a load is placed in the corresponding load-bearing area. At this time, the impedance in the detection module also changes, thereby causing the electrical signal value (i.e., the working signal) in the detection module to change. In this way, the control module can know whether there is a load and / or the type of load in the current corresponding load-bearing area by sampling the working signal of the detection module. The capacitive parameter includes but is not limited to the capacitance value.

[0091] In summary, there are many ways for the detection module to detect whether there is a load and / or the type of load, and the specific implementation is not limited to the above examples.

[0092] In some embodiments, in the carrying shell, the detection module is stacked above the integrated module. There is a first distance between the detection module and the carrying surface; there is a second distance between the integrated module and the carrying surface; wherein the first distance is smaller than the second distance.

[0093] For example, in the bearing housing, the i-th detection module is stacked above the i-th integrated module. There is a first distance between the i-th detection module and the bearing surface; there is a second distance between the i-th integrated module and the bearing surface; wherein the first distance is smaller than the second distance.

[0094] The detection module is closer to the bearing area of ​​the outer surface of the bearing shell than the corresponding integrated module. Thus, compared with setting the integrated module between the bearing area and the detection area, the detection interference of the integrated module on the detection module can be reduced, thereby improving the detection accuracy of the detection module.

[0095] Furthermore, the detection module includes:

[0096] The detection coil can interact with the load to produce different impedances;

[0097] A detection circuit connected to the detection coil and having working signals with different signal values ​​when the impedance is different;

[0098] The control module is specifically used to sample the working signal to obtain the detection signal.

[0099] In this embodiment, the detection module can be divided into at least two parts, one is the detection reel, and the other is the detection circuit.

[0100] The detection coil here can be an inductive sensing element for mutual inductance between the detection module and the load.

[0101] The detection circuit is connected to the detection coil. In this way, when the detection coil has mutual inductance with the load and the load type of the mutual inductance is different, the detection coil causes the impedance of the entire detection coil to change, and the impedance of the detection circuit also changes, so that its own working signal will change without changing the input.

[0102] In this way, the detection signal obtained by sampling the working signal by the control module will also change synchronously, so that it is possible to determine whether the corresponding bearing area has a load and / or the load type through analysis of the signal value.

[0103] In some embodiments, Figure 2 As shown, the detection line reel comprises:

[0104] An input line, connected to the power control circuit, for receiving an input signal provided by the power control circuit;

[0105] A signal line, having mutual inductance with the input line and connected to the detection circuit;

[0106] The input line and the signal line can jointly perform mutual inductance with a load.

[0107] In this embodiment, the input line and the signal line are two different lines.

[0108] The input line has a larger cross-sectional area than the signal line.

[0109] The input line is connected to a power control circuit included in the electrical device and is used to receive an input signal provided by the power control circuit.

[0110] The signal line and the input line are mutually inductive, so that the electric energy provided by the input signal of the input line can be transmitted to the detection circuit in the form of electromagnetic energy. At the same time, the signal line is connected to the detection circuit, so that there is also current and voltage in the detection circuit to generate the working signal of the detection module.

[0111] In this embodiment, the detection line tray is formed of two types of lines, namely, an input line and a signal line, and signal coupling and power transmission are achieved between the two types of lines through mutual inductance.

[0112] In other embodiments, the detection reel may be a reel including only one type of transmission line, and is not limited to the above structure.

[0113] At the same time, since the detection coil detects whether there is a load and / or the type of load through mutual inductance, the environmental parameters of the environment where the electrical equipment is located have an impact on the mutual inductance itself and the impedance change caused by the mutual inductance, so the detection coil can also be used to detect environmental parameters. The environmental parameters include but are not limited to: temperature and / or humidity.

[0114] Thus, in some embodiments, the control module is further used to determine the environmental parameters of the current environment of the electrical device based on the detection signal.

[0115] The input line and the signal line are synchronously wound as a winding whole to form the detection wire reel which is composed of a ring body with both the input line and the signal line as wire loops.

[0116] In some embodiments, the detection wire reel includes two types of wires, namely input wires and signal wires; however, the number of input wires and signal wires is not limited.

[0117] It should be noted that, in some embodiments, the number of input lines and signal lines is the same.

[0118] In some embodiments, the number of the detection wire reels may be one or more.

[0119] In this embodiment, the body of the detection wire reel is composed of synchronously wound signal wires and input wires.

[0120] For example, Figure 2 As shown, the signal wire and the input wire are wound together one by one, and each coil body of the formed coil includes: a coil of signal wire and a coil of input wire. A coil body is composed of multiple coils with the same or similar ring diameters.

[0121] In other embodiments, the signal wires and input wires may not be wound one-to-one, and the resulting wire reel may include: S1 turns of signal wires and S2 turns of input wires; S1 and S2 are both positive numbers, and may be unequal positive numbers.

[0122] In some embodiments, Figure 3 As shown, the detection circuit includes:

[0123] A first switching tube;

[0124] A second switch tube, connected in series with the first switch tube;

[0125] The signal line is connected in parallel with the second switch tube.

[0126] In this embodiment, the first switch tube and the second switch tube may be electronic components with on and off functions, such as triodes and / or MOS tubes.

[0127] exist Figure 3 The first switch tube and the second switch tube are both metal-oxide-semiconductor field-effect transistors (MOSFET), and are NMOSFET.

[0128] exist Figure 3 Among them, Lm1 is the signal line in the detection line tray; Lm2 is the input line in the detection line tray; it can be seen that the signal line is directly connected to the detection circuit; and the input line in the detection line tray has mutual inductance with the signal line.

[0129] exist Figure 3 The detection circuit is also connected with a capacitor Cs and a capacitor Cm; a sampling resistor can be set at point A of the detection circuit to sample the working signal of the detection circuit to obtain the detection signal.

[0130] In this embodiment, the first switch tube and the second switch tube are connected in series, and the signal line of the detection coil is connected in parallel with the second switch tube. In this way, if the detection coil has a load with mutual inductance, or different types of loads with mutual inductance, the impedance of the signal line changes, thus causing the impedance of the entire detection circuit to change, thereby causing the impedance of the detection circuit to change, and ultimately causing the working signal of the detection circuit to change.

[0131] Furthermore, the control module is specifically used to control the corresponding integrated module to operate in the wireless power transmission mode when the detection signal is greater than a first reference value.

[0132] If the detection signal is greater than the first reference value, it means that the current load is a legal load corresponding to the electrical device, and the load is a power transmission load, so the corresponding integrated module with load in the load-bearing area is controlled to work in the wireless power transmission mode.

[0133] In some embodiments, the control module is specifically used to control the corresponding integrated module to operate in a heating mode when the detection signal is less than a second reference value, wherein the second reference value is less than the first reference value.

[0134] In this embodiment, if the signal value of the detection signal is less than the second reference value, it is also considered that the load currently placed on the load-bearing surface is a legal load of the electrical device and is a heating load, so the corresponding integrated module is controlled to enter the heating mode.

[0135] In this embodiment, the second reference value is smaller than the first reference value.

[0136] Furthermore, the control module is also used to control the corresponding integrated module to be in a non-working state when the signal value of the detection signal is between the first reference value and the second reference value.

[0137] If the detection signal is between the first reference value and the second reference value, there is a load on the current bearing surface, but it is not a legal load of the electrical equipment (i.e., an illegal load), and the corresponding integrated module is controlled to be in a non-working state. On the one hand, this reduces the power consumption of the integrated module in the working state, and on the other hand, it can reduce the damage caused to the illegal load by the integrated module in the working state.

[0138] For example, the control module is specifically used to control the integrated module corresponding to the load-bearing area where the load is located to enter a working state and operate in the wireless power transmission mode when the signal value of the detection signal is greater than a first reference value, and to control the integrated module corresponding to the load-bearing area where the load is located to enter a working state and operate in the heating mode when the detection signal is less than a second reference value, wherein the second reference value is less than the first reference value.

[0139] For another example, the control module is further used to control the integrated module corresponding to the load-bearing area where the load is located to be in a non-working state when the signal value of the detection signal corresponding to the load-bearing area where the load is located is between the first reference value and the second reference value.

[0140] In some other embodiments, the electrical device further comprises:

[0141] A wireless communication module, used to establish wireless communication for wireless power transmission with a charging load receiving wireless power transmission when the integrated module enters the wireless power transmission mode;

[0142] The control module is connected to the wireless communication module, and is used to control the integrated module in the wireless power transmission mode to wirelessly transmit power to the charging load after the wireless communication module successfully establishes communication with the charging load.

[0143] In this embodiment, the electrical device also includes a wireless communication module, which can communicate with the charging load. The information content of the communication includes at least: transmission parameters of wireless power transmission, which may include: wireless power transmission protocol parameters followed by wireless power transmission, transmission power of wireless power transmission, transmission current and / or voltage of wireless power transmission, etc.

[0144] In some embodiments, the information content of the communication may also include: charging status information, so that the electrical device can adjust the charging power in the wireless charging mode according to the difference between the actual charging status of the charging load and the expected charging status, so that the actual charging status of the charging load is as close to the expected charging status as possible.

[0145] like Figure 4 As shown, this embodiment provides a working method of an electrical device, including:

[0146] Step S110: obtaining a detection signal formed by a detection module that can be coupled with a load, wherein the detection module is used to detect whether there is a load and the type of load in a bearing area corresponding to an integrated module; for example, the step S110 includes but is not limited to: obtaining an i-th detection signal formed by an i-th detection module that can be coupled with a load, wherein i is a positive integer less than or equal to I, I is the total number of detection modules included in the electrical device, and one detection module is used to detect whether there is a load and the type of load in a bearing area corresponding to an integrated module;

[0147] Step S120: If the detection signal indicates that a load is placed in the bearing area corresponding to the integrated module in the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load. For example, the step S120 may include: if the i-th detection signal indicates that a load is placed in the i-th bearing area where the i-th integrated module in the electrical device is located, the i-th integrated module is controlled to enter a working state, and according to the load type represented by the i-th detection signal, the i-th integrated module is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load;

[0148] The working method provided in this embodiment can be applied to the electrical equipment provided in any of the above embodiments.

[0149] In this embodiment, the working mode of the integrated module is controlled according to the load type of the bearing area of ​​the integrated module. The working mode can be a heating mode for heating the heating load or a wireless charging mode for charging the charging load.

[0150] In this embodiment, the electrical device can be used for heating the heating load and / or wireless power transmission of the charging load at the same time, and the heating load may include: cooking equipment for cooking, thereby reducing the phenomenon that different cooking equipment in the kitchen needs to be connected to the socket using different wires, and the electrical device can also be used for wireless power transmission at the location of the electrical device.

[0151] In some embodiments, one integrated module corresponds to one detection module. The detection module includes a sensing element, which performs mutual induction with a load to obtain different impedances, thereby generating different working signals, and the detection signal is obtained by sampling the working signal.

[0152] The detection signal can not only be used to determine whether there is a load in the corresponding bearing area, but also be used to reflect the load type of the load.

[0153] The step S120 may include:

[0154] Comparing the signal value of the detection signal with a reference value to obtain a comparison result;

[0155] When it is determined according to the comparison result that a load is placed in the bearing area within the electrical device, the integrated module corresponding to the bearing area where the load is located is controlled to enter a working state, and according to the load type represented by the detection signal, the integrated module corresponding to the bearing area where the load is located is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load.

[0156] For example, step S120 may include:

[0157] Compare the signal value of the i-th detection signal with the reference value to obtain a comparison result;

[0158] According to the comparison result, when it is determined that a load is placed in the i-th bearing area where the i-th integrated module in the electrical device is located, the i-th integrated module is controlled to enter a working state, and according to the load type represented by the i-th detection signal, the i-th integrated module is controlled to operate in a heating mode for heating the load or a wireless charging mode for charging the load.

[0159] In this embodiment, the reference value may be a signal value pre-written into the electrical device.

[0160] The number of the reference values ​​may be one or more.

[0161] By comparing the i-th detection signal with the reference value, a comparison result representing the magnitude relationship between the i-th detection signal and the reference value can be obtained.

[0162] Based on the fact that the comparison result corresponds to the load type, in this embodiment, the current working mode of the integrated module is directly determined according to the comparison result.

[0163] In some embodiments, comparing the signal value of the detection signal with a reference value to obtain a comparison result may include: comparing the signal value of the detection signal with a first reference value and a second reference value respectively, wherein the second reference value is less than the first reference value;

[0164] The step S120 may include: when the detection signal is greater than the first reference value, controlling the integrated module corresponding to the load-bearing area where the load is located to enter a working state and operate in the wireless power transmission mode; when the detection signal is less than the second reference value, controlling the integrated module corresponding to the load-bearing area where the load is located to enter a working state and operate in the heating mode.

[0165] For example, the signal value of the i-th detection signal is compared with a first reference value and a second reference value respectively, wherein the second reference value is smaller than the first reference value.

[0166] For example, when the i-th detection signal is greater than the first reference value, the i-th integrated module is controlled to enter the working state and operate in the wireless power transmission mode; when the i-th detection signal is less than the second reference value, the i-th integrated module is controlled to enter the working state and operate in the heating mode.

[0167] In some embodiments, the method may further include:

[0168] When the signal value of the i-th detection signal is between the first reference value and the second reference value, the i-th integrated module is controlled to be in a non-working state.

[0169] In some embodiments, the step S110 may include: acquiring the detection signal at predetermined time intervals.

[0170] In some embodiments, the interval lengths of any predetermined time intervals may be equal, thereby achieving periodic detection of the detection signal; in other embodiments, the predetermined time intervals may be different, so that the peak usage period and the off-peak usage period of the electrical equipment can be combined, and a shorter predetermined time interval can be used during the peak usage period, and a longer predetermined time interval can be used for detection during the off-peak usage period.

[0171] An embodiment of the present invention also provides a computer storage medium, which stores computer executable instructions. After the computer storage instructions are executed, the working method of the electrical equipment provided by any of the above-mentioned technical solutions can be implemented.

[0172] Several specific examples are provided below based on any of the above embodiments:

[0173] Example 1:

[0174] like Figure 5 As shown, this example provides an electrical device 1, which can be a full-surface intelligent electromagnetic cooker. The electrical device includes:

[0175] A bearing surface 11 on the surface of the stove;

[0176] Integrated modules 4 for independent heating or power transmission; the integrated modules are arranged in a matrix.

[0177] A handheld mobile phone 2 , other digital or electronic devices or apparatuses 3 , and cooking equipment such as an iron pot 5 are arranged on the carrying surface 11 .

[0178] All independent heating or power transmission modules are numbered according to certain rules, as shown in the following example: Figure 6 As shown in FIG. 1 , when the stove is powered on, the stove can automatically detect and identify the type and / or area of ​​the load on the stove. Figure 6 As shown, it is detected and identified that there is a pot above the integrated modules 5-3, 5-4, 6-3, and 6-4, and it is a cooker.

[0179] The integrated modules are arranged in a matrix, and the identification of the integrated modules can be represented by coordinates, wherein coordinate 5-3 identifies the integrated module in the 5th column and the 3rd row, and coordinate 5-4 indicates the integrated module in the 5th column and the 4th row.

[0180] The workflow of the electrical equipment provided in this example can be referred to Figure 7 As shown, including:

[0181] After the electrical device is powered on, a cyclic detection is started to detect which integrated modules on the electrical device have loads and / or load types;

[0182] Based on the detection signal obtained, it is determined whether the integrated module NM needs to work. For example, if the integrated module NM is loaded, it may need to work and enter the working state. Otherwise, it may not work and the electrical device may not enter the working state.

[0183] If yes, determine whether the corresponding integrated module needs to be heated;

[0184] If heating is required, the integrated module works in heating mode;

[0185] If heating is not required, the integrated module works in wireless power transmission mode.

[0186] Specifically, the bearing detects whether there is a load on the module NM through a loop. If there is a load, the type and area of ​​the load are determined, and whether the program requires the corresponding module to work. If the corresponding module needs to work, it works according to the work type specified by the program. By repeating this program continuously, multiple loads can work at the same time.

[0187] Integrates heating and power transmission functions, making it more practical;

[0188] Users can directly use electronic devices and tailless kitchen appliances without an external power supply, and can also place pots and pans at any location and heat them to provide a better user experience; the tailless kitchen appliances here refer to cooking equipment without power cords.

[0189] Tailless kitchen appliances do not have external power cords, making cleaning more convenient and safer.

[0190] This example also provides a method for detecting a load and / or a load type. Figure 8 As shown, including but not limited to:

[0191] The detection circuit operates at a certain frequency (e.g., 100kHz) to periodically generate a detection signal;

[0192] Detecting and analyzing the amplitude of the detection signal returned, and comparing it with a reference value;

[0193] Determine whether the signal value of the detection signal is greater than a first reference value,

[0194] If yes, the integrated module is controlled to start wireless power transmission at minimum power to provide the energy consumption required for communication establishment;

[0195] Determine whether the communication is established successfully;

[0196] If the identification is successful, the system of the corresponding integrated module starts to work, thereby controlling the integrated module to wirelessly charge the charging load in the wireless power transmission mode;

[0197] If the identification fails, the system of the corresponding integrated module stops working, that is, the integrated module is in a non-working state.

[0198] If the signal value of the detection signal is not greater than the first reference value, further determine whether the detection signal is less than the second reference value,

[0199] If the signal value of the detection signal is less than the second reference value, it is determined to be a heating load, and thus the integrated module is controlled to operate in a heating mode.
