[0002] A stove, also known as a cooker, is a gas appliance that uses the chemical energy of gas to convert into heat energy for cooking and food processing to meet household needs. Based on the type of gas used, stoves can generally be categorized into natural gas stoves, manufactured gas stoves, liquefied petroleum gas stoves, and induction cookers. During use, users adjust the heat by rotating a knob on the stove; the rotation angle of the knob corresponds to the user's desired heat level.

[0003] One common type of cooktop uses a camera to identify the rotation angle of the knobs on the cooktop and adjusts the heat to the user's desired level based on this angle. However, because cooking often involves high temperatures and pressures, cooking often produces a lot of steam, fumes, and other obstructions. These obstructions can block the knobs, affecting the camera's ability to identify the rotation angle and preventing the cooktop from accurately adjusting the heat to the user's desired level.

And the discussion of the second component, area, layer, or part does not imply that the first component, area, layer, or part necessarily exists in this application.

[0045] To make the objectives, technical solutions, and advantages disclosed in the embodiments of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the embodiments of this application and are not intended to limit the embodiments of this application.

[0046] Please see Figure 1 , Figure 1 This is a schematic diagram of a fire control device provided in an embodiment of this application. Figure 1 .like Figure 1 As shown, the fire control device includes a stove knob 1, a contact component 2, a control unit, and a base 3.

[0047] The cooktop knob 1 and the contact component 2 can be mounted on the base 3. The cooktop knob 1 can be movably mounted on the base 3 via a limiting device including a limiting shaft. The axis of the cooktop knob 1 can be perpendicular to the plane of the base 3, and the cooktop knob 1 can rotate around its own axis. The contact component 2 can be fixedly mounted on the base 3.

[0048] Optionally, the contact assembly 2 includes at least one contact element 21, which is arranged around the stove knob 1. Each contact element 21 can be spaced at a preset angle, and the angle between each contact element 21 can be designed according to actual conditions. The angle between each contact element 21 can be the same angle or different angles.

[0049] Optionally, the contact element 21 can be a device capable of contacting the stove knob 1 and generating a measurable signal based on the contact state between the contact element 21 and the stove knob 1. Specifically, when the contact element 21 contacts the stove knob 1, the contact element 21 can generate a signal indicating that the contact element 21 is in contact with the stove knob 1; when the contact element 21 separates from the stove knob 1, the contact element 21 can generate a signal indicating that the contact element 21 has separated from the stove knob 1. The contact element 21 may include a contact switch, which can be disposed in a detection circuit. The detection circuit can be used to generate the aforementioned signals indicating whether the contact element 21 is in contact with or separated from the stove knob 1.

[0050] During the rotation of the stove knob 1, each of the at least one contact member 21 is used to contact or separate from the stove knob 1. When the stove knob 1 is rotated to an angle corresponding to each contact member 21, the stove knob 1 contacts each contact member 21. When the stove knob 1 is rotated to an angle other than the angle corresponding to each contact member 21, the stove knob 1 separates from each contact member 21.

[0051] Optionally, when the stove knob 1 comes into contact with each contact member 21, the stove's firepower will switch once. The control unit is used to determine and adjust the stove's firepower based on the contact state of each contact member 21 with the stove knob 1. That is, the firepower control device can determine the firepower control mode at this time by detecting the contact state of each contact member 21 with the stove knob 1 at the current moment. When no contact member 21 is in contact with the stove knob 1, the stove's firepower remains unchanged. When a contact member 21 is in contact with the stove knob 1, the stove's firepower changes.

[0052] Optionally, the control unit may include control devices such as a control board, sensor or circuit board, and the control unit may be used to control the stove so that the stove adjusts the firepower to the required level.

[0053] In this embodiment, when the stove knob 1 is rotated to different angles, the control unit can control the stove's firepower based on the contact state between each contact member 21 and the stove knob 1, thus achieving precise adjustment of the stove's firepower. Specifically, the control unit can determine the rotation angle of the stove knob 1 based on the contact state between each contact member 21 and the stove knob 1, and control the firepower based on this rotation angle.

[0054] Please see Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of a fire control device provided in an embodiment of this application. Figure 2 , Figure 3 This is a schematic diagram of the circuit connection between the contact and detection components of a fire control device provided in an embodiment of this application. Figure 2 As shown, the stove knob 1 may include a connector 11. The stove knob 1 may be spaced apart from each contact 21. The stove knob 1 can contact each contact 21 through the connector 11. The connector 11 may be a structure capable of contacting the contact 21. When the contact 21 includes a contact switch, the connector 11 can be used to press the contact switch.

[0055] During the rotation of the stove knob 1, the connecting member 11 can rotate within at least two rotation ranges, and each of the at least two rotation ranges corresponds to a certain firepower of the stove. The rotation range of the connecting member 11 can be a rotation angle range or a rotation path range. When the connecting member 11 moves within the corresponding rotation angle range or rotation path range, the firepower of the stove is the firepower corresponding to the rotation angle range or rotation path range at that time.

[0056] Optionally, the stove may include at least two heat levels. The at least two rotation ranges of the connector 11 correspond one-to-one with the at least two heat levels of the stove, and the number of rotation ranges is consistent with the number of heat levels in the stove; that is, each rotation range of the connector 11 corresponds to a different heat level of the stove. Specifically, the connector 11 may include four rotation angle ranges: 0 to 30°, 30° to 60°, 60° to 90°, and greater than 90°. These four rotation ranges can correspond to off, low heat, medium heat, and high heat, meaning that when the connector 11 rotates from 0° to 120°, the heat level of the stove continuously increases.

[0057] Optionally, one heat level of the stove can correspond to multiple rotation ranges of the connector 11. Specifically, the connector 11 can include four rotation angle ranges: 0 to 30°, 30° to 60°, 60° to 90°, and greater than 90°. These four rotation ranges can correspond to the flame off, low heat, high heat, and low heat. That is, when the connector 11 rotates from 0° to 120°, the heat level of the stove first increases and then decreases.

[0058] The fire control device can determine the rotation range of the connector 11 at this time through the contact member 21, and then determine the stove fire power corresponding to the rotation range of the connector 11 at the current time, thereby realizing the precise adjustment of the stove fire power.

[0059] In one possible embodiment, each contact 21 corresponds to two of at least two rotation ranges, and the contact 21 can be disposed between two rotation ranges. The connector 11 in the fire control device can rotate within N rotation ranges, and the fire control device can include (N-1) contact 21s, each contact 21 being sequentially disposed between every two rotation ranges.

[0060] Specifically, the connector 11 can rotate within four rotation angle ranges: 0-30°, 30° to 60°, 60° to 90°, and greater than 90°. The contact assembly 2 can include three contacts 21, which can be correspondingly positioned at the 30° rotation angle position, the 60° rotation angle position, and the 90° rotation angle position of the connector 11.

[0061] When the connector 11 contacts each contact 21, the connector 11 can switch between the two rotation ranges corresponding to each contact 21. Optionally, the contact 21 can correspond to two rotation ranges. When the control unit detects that the contact 21 is in contact with the stove knob 1, and the stove knob 1 was in one of the two rotation ranges at the previous moment, it indicates that the stove knob 1 has now moved from one of the two rotation ranges through the contact 21 to the other rotation range. The control unit can determine and adjust the stove's firepower based on the change in rotation range, thus achieving precise adjustment of the stove's firepower.

[0062] In one possible embodiment, the fire control device further includes a detection component 4, which can be electrically connected to at least one contact 21. Specifically, the fire control device may include a detection circuit, which can be electrically connected to at least one contact 21, and the contact 21 can be a contact switch disposed in the detection circuit. The detection circuit can be used to emit a detection signal, and the detection signal emitted by the detection circuit changes accordingly when the contact switch is open or closed.

[0063] Optionally, the detection component 4 is used to obtain the contact state between each contact 21 and the stove knob 1. The detection component 4 may include a detection circuit, which can determine the contact state between each contact 21 and the stove knob 1 based on the detection signal emitted by the detection circuit, thereby determining the rotation angle of the stove knob 1 at the current moment, and then determining and adjusting the firepower of the stove.

[0064] In one possible embodiment, the detection component 4 includes at least two detection elements 41. Optionally, the detection element 41 may include an encoder, which may be arranged around the stove knob 1 and may be electrically connected to the detection element 41.

[0065] Optionally, each of the at least two detection elements 41 can be disposed on both sides of each contact element 21, and each detection element 41 is used to output a first state signal corresponding to each detection element 41. The first state signal can be a signal formed in the form of reference 1x00d2, Switch_1_0001, etc.

[0066] When any contact 21 contacts the stove knob 1, the fire control device can process the first state signal output by the detection elements 41 on both sides of any contact 21 and obtain a signal quantity that can characterize the contact of any contact 21 to the stove knob 1. When the control unit receives the signal quantity that characterizes the contact of any contact 21 to the stove knob 1, it can determine and adjust the fire based on the signal quantity.

[0067] The first status signal may further include a first feature information bit and a second feature information bit. The first feature information bit may be a machine code. The machine code emitted by the detection element 41 installed on each stove may be the same. The fire control device can identify the signal through the machine code to determine whether the source of the signal is the stove corresponding to the machine code of the signal. The second feature information bit may be a stove code. Each stove may include multiple cooking stoves, and each cooking stove has a different stove code. The fire control device can determine the cooking stove corresponding to the source of the signal based on the stove code of the cooking stove.

[0068] In one possible embodiment, the detection element 41 includes a radio frequency identification chip, and the detection element 41 can be electrically connected to a control device such as a control unit. Each detection element 41 is used to output a first status signal corresponding to each detection element 41 based on the radio frequency identification chip.

[0069] Among them, the radio frequency identification chip can transmit detection signals, including the first state signal, based on private protocols and private frequency bands. Compared with public protocols and public frequency bands, private protocols and private frequency bands have advantages such as strong anti-interference ability, simple communication data, fast communication speed, and no communication delay. Therefore, data transmission based on the detection device 41 also has advantages such as strong anti-interference ability, simple communication data, fast communication speed, and no communication delay, thus improving the transmission rate and transmission stability of information transmission.

[0070] In one specific embodiment, the contact 21 may include a contact switch, which may be disposed in a circuit capable of sending a specific signal. The detection element 41 may include the aforementioned circuit capable of sending a specific signal. The connector 11 may include a metal terminal. When the connector 11 contacts the contact 21, the metal terminal may be connected to the contact switch. Under the action of the metal terminal, the circuit capable of sending a specific signal is closed and sends the specific signal, so that the control unit can determine that the contact switch is turned on at this time through the specific signal, thereby determining the contact state of the contact 21 and the stove knob 1 at this time.

[0071] like Figure 3 As shown, the contact switch in contactor 21 can be correspondingly set... Figure 3 At the position indicated by the dotted line, the contact switch can be electrically connected to two detection elements 41 corresponding to the contact element 21. Each detection element 41 may include a radio frequency element (RF), a wireless radio frequency identification chip (RFID), and a resistor (R). The RF element and the wireless radio frequency identification chip can be connected in series, and the resistor can be connected in parallel with the RF element and the wireless radio frequency identification chip.

[0072] Optionally, the two detection elements 41 can be connected by a contact switch (KM). When the contact switch is open, each of the two detection elements 41 sends a first status signal. When the contact element 21 contacts the connecting element 11, the contact switch is turned on, and the two detection elements 41 send a second status signal together. The second status signal can be a combination of the first status signals sent by the two detection elements 41.

[0073] Optionally, the two detectors 41 each emit a first status signal corresponding to the two detectors 41. The first status signal can be a 12-bit digital signal. When the contact switch is turned on, the two detectors 41 together emit a 24-bit second status signal.

[0074] Please see Figure 4 , Figure 4 This is a schematic diagram of a stove provided in an embodiment of this application. Figure 4 As shown, this application discloses a stove, which includes any of the above-mentioned fire control devices and power supply devices. The fire control device can be connected to the power supply device, or the fire control device can be set away from the power supply device.

[0075] Optionally, the power supply device is used to supply electrical energy to the fire control device. The power supply device may include a radio frequency identification (RFID) signal receiver, and the detection element 41 may be a RFID signal transmitter including a RFID chip. The stove can remotely supply power to the fire control device through wireless communication between the RFID signal receiver and the RFID signal transmitter.

[0076] Specifically, when the radio frequency identification (RFID) signal transmitting device receives radio wave energy from the RFID signal receiving device, the RFID signal transmitting device can use the radio wave energy to generate current and transmit a detection signal corresponding to the detection element 41 to achieve the output of the detection signal.

[0077] Optionally, the wireless radio frequency identification (RFID) signal transmitting and receiving devices have advantages such as long service life, no need for battery power, low cost and easy maintenance. Furthermore, the RFID signal transmitting and receiving devices can work in harsh environments, including humid, greasy, and high-temperature environments. Therefore, stoves that use RFID signal transmitting and receiving devices for remote power supply also have advantages such as long service life, no need for battery power, low cost and easy maintenance, and adaptability to harsh environments.

[0078] This application discloses a fire control method, and embodiments of the fire control method provided in this application are described below. Please refer to... Figure 5 , Figure 5This is a flowchart illustrating a fire control method provided in an embodiment of this application. Figure 1 This specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only execution order. In actual devices, systems, or server products, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as... Figure 5 As shown, this fire control method is applied to any of the fire control devices described above, and the fire control method may include the following specific steps:

[0079] S1: In response to the control command received through the electronic control system, activate the control function.

[0080] In one possible embodiment, the fire control device can activate the control function in response to a control command received through an electronic control system. The electronic control system can be a system integrated into the control unit for executing operation commands. The fire control command can include operation commands such as fire control commands issued by the user via remote control, Bluetooth, etc., fire control commands remotely operated by the user, and program commands for scheduled fire control. Upon receiving the aforementioned fire control command, the fire control device can activate the stove's fire control function through the electronic control system.

[0081] S2: During the control process, obtain the current firepower of the stove or the rotation direction of the stove knob.

[0082] Optionally, during the control process, the current firepower of the stove or the rotation direction of the stove knob 1 can be obtained. Each time the control function is activated, the firepower control device can record the firepower control information of the stove through the control unit. The firepower control device can record the changes in firepower and the specific time each time firepower control is performed. The firepower control device can detect the rotation direction of the stove knob 1 through the detection component 4, and can detect whether the stove knob 1 is rotating clockwise or counterclockwise.

[0083] S3: Obtain the contact state of at least one contact element with the stove knob.

[0084] Optionally, the fire control device can continuously acquire the contact state of at least one contact 21 with the stove knob 1 through the detection component 4. The fire control device can acquire the contact state of at least one contact 21 with the stove knob 1 through the first state signal emitted by at least one detection component 41. If the fire control device always detects the first state signal and does not detect the second state signal, it indicates that at least one contact 21 is separated from the stove knob 1 at this time.

[0085] S4: If any of the at least one contact element is in contact with the stove knob, the control unit determines and adjusts the stove's firepower based on the current firepower or rotation direction and the contact state between the at least one contact element and the stove knob.

[0086] Optionally, if the detection component 4 detects that any one of the at least one contact 21 is in contact with the stove knob 1, specifically, it can detect a change in the first state signal and detect a second state signal, that is, indicating that the contact 21 corresponding to the second state signal is pressed at this time, the control unit can determine and adjust the stove's firepower based on the current firepower or rotation direction and the contact state between at least one contact 21 and the stove knob 1.

[0087] In this embodiment, when the stove knob 1 is rotated to different angles, the control unit can control the firepower of the stove based on the contact state between each contact member 21 and the stove knob 1, thereby achieving precise adjustment of the stove firepower.

[0088] Please see Figure 6 , Figure 6 This is a flowchart illustrating a fire control method provided in an embodiment of this application. Figure 2 .like Figure 6 As shown, when executing S3: obtaining the contact state of at least one contact element with the stove knob, the following steps can be specifically performed:

[0089] S301: Output a first status signal corresponding to each detection element through each detection element.

[0090] In one possible embodiment, the fire control device can output a first state signal corresponding to each detection element 41 through each detection element 41. The first state signal can be a signal formed in the form of reference 1x00d2, Switch_1_0001, etc. When the control unit detects the first state signal, it indicates that the contact 21 corresponding to the detection element 41 that issued the first state signal is separated from the stove knob 1.

[0091] S302: If any one of the at least one contacting element contacts the stove knob, the first state signal output by the detection element located on both sides of the contacting element is processed to obtain a second state signal corresponding to the contacting element.

[0092] Optionally, when any one of the at least one contact 21 contacts the stove knob 1, the fire control device can process the first state signal output by the detection element 41 on both sides of any contact 21 to obtain a second state signal corresponding to any contact 21. When the control unit detects the second state signal, it indicates that the contact switch in the contact 21 between the two detection elements 41 that issued the second state signal is turned on, that is, at this time the contact 21 between the two detection elements 41 that issued the second state signal contacts the stove knob 1.

[0093] In this embodiment, the contact state of each contact member 21 with the stove knob 1 can be obtained by the first detection signal output by the detection component 4 and the second state signal obtained after data processing. This enables the control unit to control the firepower of the stove based on the contact state of each contact member 21 with the stove knob 1, thereby achieving precise adjustment of the stove firepower.

[0094] Please see Figure 7 , Figure 7 This is a flowchart illustrating a fire control method provided in an embodiment of this application. Figure 3 .like Figure 7 As shown, in executing S4: If any one of the at least one contact member 21 contacts the stove knob 1, the control unit determines and adjusts the stove's firepower based on the current firepower or rotation direction and the contact state between at least one contact member 21 and the stove knob 1. Specifically, the following steps can be executed:

[0095] S401: If any one of the at least one contact 21 contacts the stove knob 1, the control unit determines and adjusts the stove's firepower based on the current firepower or rotation direction and the second state signal.

[0096] In one possible embodiment, if any contact 21 of at least one contact 21 in the fire control device contacts the stove knob 1, the fire power of the stove can be determined and adjusted by the control unit based on the current fire power or rotation direction and the second state signal.

[0097] The contact 21 currently in contact with the connector 11 can be determined by the second state signal, and the current rotation range of the connector 11 can be determined by the current firepower to control the firepower of the stove.

[0098] The following will illustrate the firepower control method through a specific embodiment, in conjunction with Tables 1 and 2. Table 1 shows the firepower adjustment method determined based on the rotation direction of the stove knob and the contact corresponding to the second state signal, while Table 2 shows the firepower adjustment method determined based on the current firepower level and the contact corresponding to the second state signal.

[0099] In one specific embodiment, the connector can rotate clockwise or counterclockwise within four rotation angle ranges: 0 to 30°, 30° to 60°, 60° to 90°, and greater than 90°. These four ranges correspond to four heat levels: off, low, medium, and high, respectively. The contact assembly can include three contacts, with the first contact positioned at a 30° rotation angle, a 60° rotation angle, and a 90° rotation angle on the connector.

[0100] Correspondingly, the fire control device may include four detection elements. The first, second, third, and fourth detection elements may be set within four rotation angle ranges: 0 to 30°, 30° to 60°, 60° to 90°, and greater than 90°. The four detection elements may be specifically set at four positions: 15°, 45°, 75°, and 105°.

[0101] When the stove knob is rotated, the first, second, third, and fourth detection elements can respectively emit first state signals in the form of 1xxxxx, 2xxxxx, 3xxxxx, and 4xxxxx. When the first contact element contacts the second contact element, the first and second detection elements can jointly generate second state signals 1xxxxx and 2xxxxx. When the second contact element contacts the third contact element, the second and third detection elements can jointly generate second state signals 2xxxxx and 3xxxxx. When the third contact element contacts the fourth contact element, the third and fourth contact elements can jointly generate second state signals 3xxxxx and 4xxxxx.

[0102] During the testing process, the control unit can first check whether 1xxxxx2xxxxx is generated between the first and second detection components, then check whether 2xxxxx3xxxxx is generated between the second and third detection components, and finally check whether 3xxxxx4xxxxx is generated between the third and fourth contact components. If no second state signal is generated, it indicates that no contact component is in contact with the stove knob at this time.

[0103] Optionally, when a second state signal is detected, the control unit can determine and adjust the firepower of the stove based on the rotation direction of the stove knob or the current firepower level and the contact corresponding to the second state signal.
