[0035] In a specific embodiment, the transmitting device 4 and the receiving assembly are matched and arranged, and the fire state of the stove can be determined according to the conduction state of each receiving device under the action of the transmitting device 4 during the rotation of the knob, such as high fire state, medium or low fire state, off fire state, etc. The mounting seat can be a stove panel, or a mounting plate independent of the stove panel. The rotation process of the stove knob includes a counterclockwise rotation process from the initial position to the maximum rotation position, and a clockwise rotation process from the maximum rotation position back to the initial position.

[0036] In a specific embodiment, when the knob housing 5 is in the initial position, the cooker is in the off state, and the target receiving device 1 among at least three receiving devices is set corresponding to the transmitting device 4, that is, the target receiving device 1 and the transmitting device 4 are located in an overlapping (facing) area, and other receiving devices 2 can be set at a critical position corresponding to the change in the fire power state of the cooker. Specifically, taking the receiving assembly including three receiving devices ABC as an example, the installation position of the target receiving device A corresponds to the position where the cooker is in the off state, and the installation position of the other receiving devices BC corresponds to the critical position of the change between the medium, small and high fire states of the cooker, wherein the other receiving devices 2 are the receiving devices other than the target receiving device 1 among the at least three receiving devices.

[0037] In the embodiments of this specification, Figure 1-2 As shown, at least three receiving devices are located in the target plane, and there is a preset angle between the connection lines of the at least three receiving devices and the target point; the target point is the intersection between the rotation axis of the knob housing 5 and the target plane.

[0038] Specifically, at least three receiving devices are evenly dispersed at a preset angle α relative to the center of the circle corresponding to the installation area 3 in the target plane, and the preset angle α can be set according to the relationship between the knob rotation angle and the firepower of the stove.

[0041] Specifically, Figure 1-3 As shown, the launch device 4 can be fixedly mounted on the valve stem 6, and correspondingly, each receiving device is mounted on the mounting seat; the launch device 4 can also be fixedly mounted on the mounting seat, and correspondingly, each receiving device is mounted on the corresponding valve stem 6. The number of valve stems 6 can be determined according to the number of launch devices 4 or receiving devices installed on the valve stem 6.

[0042] In some embodiments, the transmitting device 4 is fixedly disposed in the knob housing 5, and a target receiving device 1 and other receiving devices 2 are sequentially disposed on the mounting seat along the target rotation direction of the knob housing 5; the target rotation direction is the direction in which the knob housing 5 rotates from the initial position.

[0043] Specifically, the target rotation direction is the direction in which the knob housing 5 rotates counterclockwise from the initial position. Figure 1 As shown, taking the receiving assembly including three receiving devices A1B1C1 as an example, when the receiving assembly is fixedly arranged on the mounting base, the receiving device A1, the receiving device B1 and the receiving device C1 are arranged in sequence along the counterclockwise rotation direction of the knob.

[0044] In one embodiment, the transmitting device 4 is fixedly mounted on a mounting seat, and along the target rotation direction of the knob housing 5 , other receiving devices 2 and a target receiving device 1 are sequentially mounted on the mounting seat.

[0045] Specifically, Figure 2 As shown, taking the receiving assembly including three receiving devices A2B2C2 as an example, when the receiving assembly is fixedly arranged on the mounting base, the receiving device C2, the receiving device B2 and the receiving device A1 are arranged in sequence along the counterclockwise rotation direction of the knob. Specifically, the position of the receiving device C2 and the above-mentioned receiving device A1 may overlap, in which case, the installation area 3 where the receiving devices B1 and C1 are located does not overlap with the installation area 3 where the receiving devices B2 and A1 are located.

[0046] In some embodiments, Figure 4 As shown, the transmitting device 4 is an infrared transmitting device 4, and each receiving device is an infrared receiving device. When any infrared receiving device receives the light signal emitted by the transmitting device 4, any infrared receiving device is in a conducting state; the infrared transmitting device 4 includes a first diode LED1 and a first resistor R1, and each infrared receiving device includes a second diode LED2, a phototransistor Q1, a second resistor R2, a third resistor R3 and a fourth resistor R4; one end of the first resistor R1 is connected to the anode of the first diode LED1, and the other end of the first resistor R1 and one end of the third resistor R3 are both connected to one end of the second resistor R2, and the third resistor R4 is connected to the anode of the first diode LED1. One end of the second resistor R2 is connected to the cathode of the second diode LED2, the other end of the third resistor R3 is connected to the collector of the phototransistor Q1, one end of the fourth resistor R4 is connected between the second resistor R2 and the second diode LED2, the other end of the fourth resistor R4 is connected to the base of the phototransistor Q1, the cathode of the first diode LED1, the anode of the second diode LED2 and the emitter of the phototransistor Q1 are all grounded; when the second diode LED2 receives the light signal emitted by the first diode LED1, the second diode LED2 is in a conducting state and the phototransistor Q1 is in a non-conducting state.

[0047] In a specific embodiment, the infrared emitting device 4 is a light-emitting device that can convert electrical energy into infrared light and radiate, and the infrared receiving device can receive infrared light. In the absence of infrared light, there is a small saturated reverse leakage current (dark current), and the infrared receiving device is in a non-conducting state; in the presence of infrared light, the saturated reverse leakage current increases to form a photocurrent, and the infrared receiving device is in a conducting state. The first diode LED1 is an infrared emitting tube, the second diode LED2 is an infrared receiving tube, the first resistor R1, the third resistor R3 and the fourth resistor R4 are used for current limiting, the second resistor R2 is used for voltage division with the second diode LED2, and the phototransistor Q1 acts as a switch in the circuit.

[0048] Specifically, the resistance values ​​of the first resistor R1 and the third resistor R3 can be similar or the same, usually in the hundreds of ohms, the resistance value of the fourth resistor R4 can usually be in the thousands of ohms, and the resistance value of the second resistor R2 can usually be in the tens of thousands of ohms. When the second diode LED2 does not receive infrared light, it is in a non-conducting state, which is equivalent to a resistor with a large resistance value (megaohm level). When the second diode LED2 receives infrared light, it is in a conducting state.

[0049] In actual application, during the rotation of the knob, the first diode LED1 in the infrared emitting device 4 emits infrared light. When the second diode LED2 in any infrared receiving device receives the infrared light, the second diode LED2 is in a conducting state, so that the second resistor R2 and the circuit where the second diode LED2 is located are conducting, so that the base level of the phototransistor Q1 is pulled down to GND, the phototransistor Q1 is cut off, and the voltage of the output terminal OUT is pulled up to the VCC voltage (power supply voltage) by the third resistor R3, that is, the output terminal OUT outputs a high level (1); when the second diode LED2 in any infrared receiving device does not receive infrared light, the second diode LED2 is in a non-conducting state, so that the circuit where the second resistor R2 and the second diode LED2 are located are non-conducting, so that the base level of the phototransistor Q1 is pulled up to VCC by the second resistor R2, the phototransistor Q1 is conducting, and the voltage of the output terminal OUT is pulled down to GND, that is, the output terminal OUT outputs a low level (0).

[0050] Specifically, during the rotation of the knob, the infrared transmitting module overlaps (faces) an infrared receiving module. At this time, the infrared receiving module receives the infrared light emitted by the infrared transmitting module, and the infrared receiving module outputs a high level (1), otherwise the infrared receiving module outputs a low level (0).

[0051] In some embodiments, the transmitting device 4 is a magnetic part, and each receiving device is a magnetic sensing part. When the magnetic sensing part senses the magnetic field of the magnetic part, the magnetic sensing part is in an on state; the magnetic sensing part includes a contact switch K1, and when the magnetic sensing part senses the magnetic field of the magnetic part, the contact switch K1 is closed.

[0052] In a specific embodiment, Figure 5 As shown, the magnetic induction component may further include a fifth resistor R5. When the magnetic induction component senses the magnetic field of the magnetic component, the contact switch K1 is closed and turned on, and the output terminal OUT is connected to GND, that is, the output terminal OUT outputs a low level (0); when the magnetic induction component does not sense the magnetic field of the magnetic component, the contact switch K1 is opened and not turned on. The voltage of the output terminal OUT is pulled up to the VCC voltage by the fifth resistor R5, and the output terminal OUT outputs a high level (1).

[0053] Specifically, the magnetic part can be a strong magnet, and the magnetic sensing part can be a reed switch. When the reed switch senses a magnetic field, the contact switch K1 is closed, and when the reed switch does not sense a magnetic field, the contact switch K1 is disconnected. In practical applications, when a strong magnet overlaps (faces) any reed switch, the contact switch K1 is closed, and the reed switch circuit outputs a low level (0); when the magnet and the reed switch do not overlap, the contact switch K1 is disconnected, and the reed switch circuit outputs a high level (1).

[0054] In practical applications, based on the above-mentioned knob assembly, during the knob rotation process, under the action of the transmitting device 4, the high and low level states output by each receiving device can be obtained, and the high and low level states can be used to characterize the conduction state of the receiving device, and the conduction state information of multiple receiving devices can be spliced ​​to obtain the conduction state information of the receiving assembly including multiple receiving devices. In the overall process of the knob rotating from the initial position to the maximum rotation position (usually counterclockwise) and the knob rotating from the maximum rotation position back to the initial position (usually clockwise), multiple conduction state information can be obtained based on the above method. However, one conduction state information may correspond to multiple firepower state information of the stove, and it is difficult to judge the firepower state of the stove only based on the conduction state information of the receiving assembly. Afterwards, the above-mentioned conduction state information is processed accordingly so that the processed information can be used to accurately judge the firepower state of the stove, that is, one processed information corresponds to one firepower state information, so that the combined information of the conduction state information and the auxiliary identification information can be unique by adding auxiliary identification information, and the firepower state of the stove can be accurately judged based on the information.

[0055] Specifically, the auxiliary identification information can be obtained through the above-mentioned conduction state information, and the conduction state information at the current moment is used as the current conduction state information, and the conduction state information at the previous moment before the current moment is used as the historical conduction state information. On the one hand, from the historical moment to the current moment, the conduction state information of a receiving device changes from the conduction state to the non-conduction state, or from the non-conduction state to the conduction state. The current auxiliary identification information can be determined based on the historical auxiliary identification information of the receiving device, so that the auxiliary identification information of the receiving device at the current moment is different from the auxiliary identification information at the historical moment; otherwise, the auxiliary identification information of the receiving device at the current moment is the same as the auxiliary identification information at the historical moment. For example, when the current conduction state information is the conduction state information 001 when the knob is rotated counterclockwise to overlap the transmitting device 4 and the receiving device C, and the historical conduction state information is the conduction state information 000 when the knob is rotated counterclockwise to between the receiving device B and the receiving device C, the conduction state information output by the receiving device C changes from 0 to 1, and the historical auxiliary identification information corresponding to the receiving device C is 0, then it can be determined that the current auxiliary identification information corresponding to the receiving device C is different from the historical auxiliary identification information, that is, the current auxiliary identification information corresponding to the receiving device C is 1. When the current conduction state information is the conduction state 000 when the knob is rotated counterclockwise to between the receiving device C and the maximum rotation position, and the historical conduction state information is the conduction state information 001 when the knob is rotated counterclockwise to overlap the transmitting device 4 and the receiving device C, the conduction state information output by the receiving device C changes from 1 to 0, and the historical auxiliary identification information corresponding to the receiving device C is 1, then it can be determined that the current auxiliary identification information corresponding to the receiving device C is different from the historical auxiliary identification information, that is, the current auxiliary identification information corresponding to the receiving device C is still 1.

[0056] On the other hand, the auxiliary identification information can be determined based on the change information between the current conduction state information corresponding to each receiving device and the historical auxiliary identification information, wherein the historical auxiliary identification information is the auxiliary identification information corresponding to the previous moment of the current moment, and the current change information can be used to indicate whether the current conduction state information corresponding to each receiving device is consistent with the historical conduction state information corresponding to the receiving device. When the current change information indicates that the current conduction state information of the corresponding receiving device is inconsistent with the historical auxiliary identification information, the third preset information is determined as the current auxiliary identification information of the corresponding receiving device; when the current change information indicates that the current conduction state information of the corresponding receiving device is consistent with the historical auxiliary identification information, the fourth preset information is determined as the current auxiliary identification information of the corresponding receiving device. Specifically, the third preset information and the fourth preset information can be set according to actual application requirements, and can be set to 1 or 0, and the third preset information and the fourth preset information are different. For example, when the current conduction state information of the receiving device is inconsistent with the historical auxiliary identification information, the current auxiliary identification information of the corresponding receiving device is set to 0; when the current conduction state information of the receiving device is consistent with the historical auxiliary identification information, the current auxiliary identification information of the corresponding receiving device is set to 1.

[0057] Furthermore, based on the same order of the conduction state information corresponding to each receiving device in the conduction state information corresponding to the receiving component, the auxiliary identification information corresponding to each receiving device is spliced ​​to obtain the auxiliary identification information corresponding to the receiving component. Afterwards, the conduction state information corresponding to the receiving component and the auxiliary identification information corresponding to the receiving component are spliced ​​to obtain the firepower identification information corresponding to the receiving component. Based on the firepower identification information and the preset mapping relationship, the firepower state information corresponding to the stove is determined, wherein the preset mapping relationship can be used to characterize the correspondence between the firepower identification information of the receiving component and the firepower state information of the stove. The firepower identification information of the receiving component only corresponds to one corresponding firepower state information, and the specific firepower state of the stove can be accurately judged according to the firepower identification information. Based on the above method, the firepower degree of the stove can be quickly and effectively identified, and the accuracy and reliability of the stove firepower identification can be improved.

[0058] It can be seen from the technical solutions provided by the above embodiments of this specification that a knob assembly in this specification is used for a stove, the knob assembly includes a knob housing and a firepower identification assembly, the firepower identification assembly includes a relatively arranged transmitting device and a receiving assembly, the target device is fixedly arranged in the knob housing, the other devices are fixedly arranged on the mounting seat, and the knob housing rotates relative to the mounting seat; the target device is any one of the transmitting device and the receiving assembly, and the other device is the other one of the transmitting device and the receiving assembly except the target device; the receiving assembly includes at least three receiving devices, at least three receiving devices are dispersedly arranged at preset intervals on the rotation path of the knob housing, each receiving device is fixedly arranged in the knob housing or each receiving device is fixedly arranged on the mounting seat; when the knob housing is in the initial position, the stove is in the off state, and the target receiving device among the at least three receiving devices corresponds to the transmitting device. During the rotation of the knob, based on the conduction of at least three receiving devices under the action of the transmitting device, the firepower state of the stove can be effectively identified, and the accuracy and reliability of the stove firepower identification can be improved.

[0059] An embodiment of the present application further provides a cooker, comprising a first control device and the above-mentioned knob assembly, wherein a transmitting device and at least three receiving devices are electrically connected to the first control device.

[0060] Specifically, the first control device can be used to control the transmitting device to generate / transmit corresponding signals when the knob starts to turn and during the rotation process, and to obtain the conduction status information output by each receiving device, and then perform the above-mentioned corresponding processing based on the conduction status information to obtain the firepower identification information, so as to realize the identification of the firepower status of the stove based on the firepower identification information. The first control device can also set the operation time of the stove according to the firepower status of the stove, so that the stove can automatically turn off the fire after the stove continues to run for a long time with the current firepower status information. The above-mentioned operation time can be set according to actual application requirements. For example, when the current firepower status information of the stove is a high-fire state, the operation time can be set to 30 minutes; when the current firepower status information of the stove is a medium-small fire state, the operation time can be set to 1 hour.

[0061] An embodiment of the present application also provides an integrated cooking device, including a range hood extraction device, a second control device and the above-mentioned cooker, wherein the first control device and the range hood extraction device are both electrically connected to the second control device.

[0062] Specifically, the integrated cooking device may be any cooking device including a stove and a range hood device with corresponding functions, such as an integrated stove. The second control device is used to obtain the stove firepower status information sent by the first control device, and then determine the gear information of the range hood device based on the firepower status information, and control the range hood device to operate with the gear. Specifically, the gear information of the range hood device may include strong gear information, weak gear information and closed gear information. When the current firepower status information is a high-fire state, the current gear information of the range hood device is determined as a strong gear information, and the range hood device operates at a strong gear; when the current firepower status information is a medium or small fire state, the current gear information of the range hood device is determined as a weak gear information, and the range hood device operates at a weak gear; when the current firepower status information is an off-fire state, the current gear information of the range hood device is determined as a closed gear information, and the range hood device stops operating.

[0063] The embodiment of the present application can divide the control device into functional units according to the above examples. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated module can be implemented in the form of hardware or in the form of software functional modules.
