[0055] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0056] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0057] Example 1

[0058] like Figure 1-4As shown, this embodiment provides a method for controlling a stove and a range hood in a coordinated manner, which is applicable to a range hood. The stove includes a knob disposed on a stove panel 1, which includes a knob cover 2. Rotating the knob cover 2 drives the knob to adjust the stove's heat intensity.

[0059] The cooktop of this embodiment also includes a rotation detection device, which comprises: a magnetic element 3 mounted on the bottom surface of the knob cover 2; a plurality of magnetic detection elements 4 mounted on the bottom surface of the cooktop panel 1 (each magnetic detection element 4 is integrated into a housing 5); and a signal transmission circuit 6 electrically connected to each magnetic detection element. The plurality of magnetic detection elements 4 are arranged corresponding to the rotation path of the magnetic element 3 (specifically, located directly below the rotation path of the magnetic element 3) and are spaced apart from each other, with the position of one of the magnetic detection elements 4 corresponding to the initial position of the magnetic element 3.

[0060] When the knob cover 2 rotates, since the magnetic element 3 is arranged on the bottom surface of the stove knob cover 2 and is spaced apart corresponding to the rotation path of the magnetic element 3, each magnetic detection element 4 can detect whether the magnetic element 3 has reached the corresponding position, and the detection result can be uploaded to the range hood end via the signal transmission circuit 6. Among them, the signal transmission circuit 6 can be integrated into the housing 5 together with the magnetic detection element 4, which is easy to disassemble, highly portable, flexible and convenient. Preferably, the signal transmission circuit 6 includes a wireless transmission module 61, which is preferably implemented using a 2.4G wireless module. Compared with the commonly used infrared communication module and the 633Mhz superheterodyne communication module, the 2.4G wireless module has stronger anti-interference performance and is not easily interfered by external objects and crosstalk.

[0061] Preferably, the magnetic element 3 can be a strong magnet, and the magnetic detection element 4 can be a Hall element. Specifically, the magnetic detection element 4 can adopt the Hall element ES3144, which has an integrated Hall effect chip. The ES3144 Hall element has high reliability, ultra-small and ultra-thin packaging characteristics, strong anti-interference ability, and can only sense magnetism and output signals within a space with a diameter range of 10 cm. In this embodiment, each Hall element is integrated into the housing 5, and the distance from other electronic devices is far greater than 10 cm. Therefore, other electronic devices in the kitchen will not affect the detection results of each Hall element.

[0062] When the S pole of a strong magnet approaches the element surface and the magnetic induction intensity B generated by the strong magnet is greater than the element's operating point magnetic induction intensity B_O (i.e., B>B_O>0), the output is on and the Hall element outputs a low level. When the magnetic induction intensity B is less than the release point magnetic induction intensity B_RP (i.e., 0<B<B_RP) or is removed (i.e., B=0), the output is off and the Hall element outputs a high level. The relationship between the position of the strong magnet and the Hall element output is shown in Table 1.

[0063] Table 1 Relationship between the position of strong magnet and the output of Hall element

[0064] Strong magnet and Hall position Magnetic induction intensity Hall element output Close to (facing) <![CDATA[B>B O >0]]> Low level keep away <![CDATA[0<B<B RP ]]> High level

[0065] Based on the aforementioned rotation detection device, the linkage control method provided in this embodiment is as follows: Figure 5 As shown, the specific steps include:

[0066] S1, obtaining detection results of the plurality of magnetic detection elements, wherein the detection results are used to indicate whether the magnetic elements have reached positions corresponding to the corresponding magnetic detection elements.

[0067] In this embodiment, the detection results of the magnetic detection elements can be received by a signal receiving circuit provided at the range hood end. The signal receiving circuit includes a wireless receiving module for exchanging data with the aforementioned wireless transmitting module. The wireless receiving module is also preferably implemented using a 2.4G wireless module.

[0068] S2, determining the fire intensity corresponding to the stove according to the detection result, and adjusting the wind speed level of the range hood according to the fire intensity.

[0069] The following describes step S2 in detail using a specific application scenario:

[0070] Typically, a stove knob can rotate 180 degrees counterclockwise. When 0 ≤ θ < 90 degrees, the greater the counterclockwise rotation angle θ, the greater the stove power. When θ = 90 degrees, the power reaches maximum. When 90 < θ ≤ 180 degrees, the greater the counterclockwise rotation angle θ, the lower the power. Within the 180-degree range of the knob rotation, three gears are defined: low heat, medium heat, and high heat. Low heat: 0 < θ ≤ 30 degrees and 150 degrees < θ ≤ 180 degrees; medium heat: 30 < θ ≤ 60 degrees and 120 degrees < θ ≤ 150 degrees; high heat: 60 < θ ≤ 120 degrees.

[0071] On this basis, the diagram of knob rotation angle and firepower intensity is as follows Figure 6 As shown, the corresponding relationship is as follows Figure 7 shown. Figure 6 The middle Hall element A is located at the off position (i.e. the initial position of the magnetic element), and the Hall elements B and C are located at the two critical positions of medium fire and high fire, and the three form a 60-degree angle relative to the center O of the knob cover 2.

[0072] Depend on Figure 6As can be seen, Hall element A is set in its initial position, where the cooktop knob is not turned. When the cooktop knob begins to turn from this initial position, the magnetic field near Hall element A changes, and this detection data is sent to the range hood, allowing the range hood to detect that the cooktop is turned on. When the cooktop knob is turned from a non-initial position back to its initial position, the magnetic field near Hall element A changes again, allowing the range hood to detect that the cooktop is turned off.

[0073] Hall element B is located at the point where the stove knob is rotated 60 degrees counterclockwise from its initial position. The stove has three power levels (high, medium, and low), and Hall element B is set at the border between medium and high.

[0074] Hall effect element C is detected when the cooktop knob is rotated 120° counterclockwise from its initial position. Hood hoods are generally configured in two settings: high and low. When cooking over low or medium heat, the amount of oil smoke is low, so the low setting is used. When cooking over high heat, the amount of oil smoke is high, so the high setting is used.

[0075] When the magnetic field near Hall element B or C changes, that is, when the stove power is adjusted between medium and high, the range hood gear switches between strong and weak gears.

[0076] In the specific operation process, assuming that the output signal of Hall element A is OUTA, the output signal of Hall element B is OUTB, and the output signal of Hall element C is OUTC, then when the user turns on the stove, the strong magnet inside the knob and Hall element A below the panel are connected and disconnected, Hall element A outputs a high level, and OUTA is also high. When the user turns on the stove and adjusts the fire intensity from low to medium, and then from medium to high, Hall element B and the strong magnet are first disconnected, then instantly connected and disconnected again, successively outputting a high level, a low level, and a high level. OUTB also outputs a high level, a low level, and a high level. When OUTB outputs a low level, it indicates that the fire intensity is fluctuating between medium and high. As the user continues to turn the knob, the fire intensity is adjusted from high to medium. The Hall element C and the magnet are first disconnected, then connected instantaneously and disconnected again. It outputs high level, low level and high level in sequence, and OUTC also outputs high level, low level and high level in sequence. When it is detected that OUTC outputs a low level, it means that the fire intensity fluctuates between high fire and medium fire. When the user turns off or does not use the stove, the strong magnet inside the knob is connected to the Hall element A under the panel, and the Hall element A outputs a low level, and OUTA is a low level.

[0077] In this embodiment, if Figure 4As shown, the signal transmission circuit may also include a signal stabilization module 62 connected between a number of magnetic detection elements 4 and a wireless transmission module 61. Specifically, the signal stabilization module can be implemented using a voltage comparator, such as the voltage comparator LM339. LM339 internally integrates 4 independent voltage comparators. The principle of the voltage comparator is to determine the level state of the output terminal by comparing the magnitudes of the two voltages at the input terminals. When the positive input terminal level is greater than the negative input terminal level, the output is a high level; when the positive input terminal level is less than the negative input terminal level, the output is a low level. The output pins of ES3144 Hall elements A, B and C are connected to the positive input terminals 1IN+, 2IN+, and 3IN+ of LM339 respectively, and the negative input terminal of LM339 is connected to a voltage divider circuit, and the negative input terminal level of LM339 is VCC / 2, that is, V 1 IN- =V 2 IN- =V 3 IN- =VCC / 2. When the positive input level of LM339 is greater than VCC / 2, OUTA, OUTB, and OUTC output high level, that is, when the strong magnet is away from the Hall elements A, B, and C, V 1 IN+ =V 2 IN+ =V 3 IN+ =VCC>Vcc / 2; When the positive input terminal level is less than VCC / 2, OUTA, OUTB, and OUTC output low level, that is, when a strong magnet and Hall elements A, B, and C are close to each other, V 1 IN+ =V 2 IN+ =V 3 IN+ =0 <Vcc / 2。

[0078] Since the signal output by the Hall element ES3144 is a high and low level, connecting the ES3144 Hall element to the LM339 element can make the level signal output by the ES3144 Hall element more stable.

[0079] The relationship between the user's firepower and the output of Hall elements A, B, C and the LM339 voltage comparator is shown in Table 2 (where "1" represents a high level, "0" represents a low level, "111" represents that the LM339 outputs OUTA, OUTB, and OUTC all output a high level, and so on).

[0080] Table 2 Relationship between firepower intensity and output of each component

[0081]

[0082]

[0083] In addition, since the general 2.4G wireless module only leads to two IO ports, and LM339 outputs three-way level signals, Figure 4As shown, the signal transmission circuit of this embodiment may further include a signal merging module 63 connected between the plurality of magnetic detection elements 4 and the wireless transmission module 61. Specifically, the signal merging module may be implemented using a 74LS08 two-input four-AND gate chip. The three-way level signal output by the LM339 is processed by AND gates U1 and U2 of the 74LS08 chip, so that the three-way output signal is converted into two-way output signals OUT1 and OUT2. The 74LS08 is a two-input four-AND gate integrated circuit chip. When all the inputs of one AND gate are high, the corresponding output is high. The conversion principle is as follows: Figure 8 shown.

[0084] When the user uses medium or low heat, the range hood automatically switches to a weak setting; when the user uses high heat, the range hood automatically switches to a strong setting.

[0085] The 2.4G wireless module only transmits information that changes. That is, it transmits information only when the current output of Hall elements A, B, and C differs from the previous output. The smoke and stove linkage transmission protocol instructions are shown in Table 3.

[0086] Table 3 Smoke and stove linkage data transmission protocol

[0087]

[0088]

[0089] It can be seen from the above table that when the user adjusts the stove knob, if step S2 is based only on the current detection results of each magnetic detection element, it cannot accurately determine whether the stove is high or medium or low. Therefore, it is also necessary to combine the historical detection results of each magnetic detection element (such as the previous detection results) to determine the fire intensity of the stove, and then adjust the wind speed level of the range hood accordingly according to the fire intensity to achieve the linkage between the range hood and the stove.

[0090] In addition, see again Figure 4 The signal transmission circuit 6 of this embodiment further includes a power supply module for supplying power to various components. The power supply module may include a power supply 64 and a voltage stabilizing circuit 65, wherein the power supply 44 is preferably a battery, such as two CR2302 button batteries.

[0091] This embodiment first obtains detection results from several magnetic detection elements installed on the bottom surface of the cooktop panel. These detection results indicate whether the magnetic elements installed on the bottom surface of the cooktop knob cover have reached the corresponding position. Based on these detection results, the corresponding fire intensity of the cooktop is determined and the wind speed level of the range hood is adjusted accordingly, thereby achieving linkage between the cooktop and the range hood. Compared with existing solutions that rely on cameras to detect cooktop knob rotation information, this embodiment is not affected by ambient smoke and has higher linkage accuracy.

[0092] Example 2

[0093] In order to prevent the user from frequently adjusting the firepower of the stove, which results in the range hood switching between high and low gears, this embodiment further improves on embodiment 1. In this embodiment, the linkage control method further includes the following steps:

[0094] S3, determining that the magnetic detection elements other than the one magnetic detection element are critical detection elements, wherein each of the critical detection elements is set to a critical position corresponding to a different firepower intensity.

[0095] For example, Figure 6 As shown, Hall elements B and C are located at the two critical points of medium fire and high fire, so they are determined to be critical detection elements.

[0096] S4. When the detection results of each of the magnetic detection elements indicate that the magnetic element passes through the position corresponding to a single critical detection element N times in a row, the wind speed level of the range hood is adjusted according to the length of time between each two adjacent passes of the magnetic element through the single critical detection element, where N is greater than or equal to 3.

[0097] Specifically, first, the maximum duration among the said durations is determined; then, based on the detection results of each of the said magnetic detection elements, the fire intensity corresponding to the stove within the said maximum duration is obtained; finally, based on the fire intensity corresponding to the stove within the said maximum duration, the wind speed level of the range hood is adjusted.

[0098] like Figure 6 As shown, when the detection result indicates that the magnetic element passes through Hall element B or C three times in a row and only the magnetic field of the single element changes between the three times, without affecting the magnetic field of other Hall element accessories (that is, the magnet only rotates near Hall element B / C, causing the magnetic field near Hall element B / C to change three times in a row, and will not cause the magnetic field of other Hall element accessories to change during the three times), then the duration of the three changes is judged. If the knob stays at high fire for a longer time during the three changes, the range hood maintains working in the strong gear; if the knob stays at low fire and medium fire for a longer time during the three changes, the range hood maintains working in the weak gear.

[0099] Afterwards, based on the detection results of each magnetic detection element, it is determined whether the magnetic element passes through the positions corresponding to other magnetic detection elements except the single critical detection element. If so, the corresponding number of consecutive passes is reset to zero, and the process returns to step S2.

[0100] By adopting the above steps, this embodiment can avoid the problem of users frequently adjusting the firepower of the stove, which causes the range hood to frequently switch between high and low gears, thereby increasing the service life of the range hood.

[0101] Example 3

[0102] This embodiment is a further improvement of embodiment 1 or 2. Specifically, before executing step S1, the linkage control method of this embodiment further includes the following steps: performing linkage pairing with the cooker. Figure 9 The specific pairing process is as follows:

[0103] When the stove knob is turned on, the wireless sending module sends the stove power-on instruction and the module's address information continuously for a first preset time (eg, 10 seconds).

[0104] Within 10 seconds, if the range hood is in the range hood and stove linkage pairing mode, the wireless receiving module on the range hood receives and stores the address information of the wireless transmitting module on the stove, and then returns the address information of the wireless receiving module to the stove. At this time, the range hood will give an audible and visual prompt to indicate that the pairing is successful. The stove receives and stores the address information of the range hood, and then stops sending information from the wireless transmitting module on the stove, thereby reducing power consumption.

[0105] Within 10 seconds, if the range hood is not in the range hood and stove linkage, the stove sends information continuously for 10 seconds. If no address information is received from the range hood within 10 seconds, the stove stops sending information after 10 seconds to reduce power consumption, and the pairing fails at this time.

[0106] When the pairing is successful, Figure 10 As shown, when the stove is turned on next time, the stove end will send a power-on command (01) and address information (stove address information + range hood address information) to the range hood end, and send it continuously for a second preset time (such as 20 seconds). The range hood end first determines whether the address information exists with its own address information, and then determines whether the stove end's address information has existed before.

[0107] Within 20 seconds, if both judgments are true, the range hood starts up and the range hood returns a successful startup command to the stove end and stops sending information from the stove end, thereby reducing power consumption.

[0108] Within 20 seconds, if one of the two judgments is not true, the range hood will not start up. At this time, the stove end has not received the power-on command information returned by the range hood within 20 seconds. The stove end sends the information continuously for 20 seconds and stops sending data after 20 seconds, thereby reducing power consumption.

[0109] Furthermore, range hoods typically have two settings: high and low. When the user presses the high setting button, the range hood enters high mode; when the user presses the low setting button, the range hood enters low mode. In this embodiment, the priority of adjusting the range hood's wind speed level based on the detection results of the magnetic detection element is higher than the priority of adjusting the range hood's wind speed level based on the key information input by the user, ensuring that the range hood's wind speed level corresponds to the stove's heat intensity.

[0110] Example 4

[0111] This embodiment provides a linkage control device for a stove and a range hood, which is applicable to the range hood. Figure 1-4 As shown, the stove includes a knob arranged on a stove panel 1, and the knob includes a knob cover 2. When the knob cover 2 is rotated, the knob can be driven to adjust the fire intensity of the stove.

[0112] The cooktop of this embodiment also includes a rotation detection device, which comprises: a magnetic element 3 mounted on the bottom surface of the knob cover 2, a plurality of magnetic detection elements 4 mounted on the bottom surface of the cooktop panel 1, and a signal transmission circuit 6 electrically connected to each magnetic detection element. The plurality of magnetic detection elements 4 are arranged corresponding to the rotation path of the magnetic element 3 (specifically, located directly below the rotation path of the magnetic element 3) and are spaced apart from each other, with the position of one of the magnetic detection elements 4 corresponding to the initial position of the magnetic element 3.

[0113] Based on the aforementioned rotation detection device, the linkage control device provided in this embodiment is as follows Figure 11 As shown, the device 8 specifically includes:

[0114] a detection result acquisition module 81, configured to acquire detection results of the plurality of magnetic detection elements through the signal receiving circuit 7, wherein the detection results are used to indicate whether the magnetic elements have reached positions corresponding to the respective magnetic detection elements;

[0115] The first linkage adjustment module 82 is used to determine the fire intensity corresponding to the stove according to the detection result, and adjust the wind speed level of the range hood according to the fire intensity.
