[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from stove combustion and the fumes that are harmful to the human body generated during the cooking process and discharge them outdoors, reducing pollution, purifying the air, and also providing safety protection against poison and explosion.

[0003] The air guide plate of the range hood is a relatively important component, which can control the opening and closing of the rear air inlet. At present, a solution is proposed to collect the burner temperature through the pyroelectric module on the range hood and control the switch of the air guide plate of the range hood based on the burner temperature.

[0004] The thermal release module on the range hood is far away from the burner. Long-distance temperature detection cannot guarantee the accuracy of the detected temperature data.

[0061] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0062] In order to at least partially solve the above technical problems, the embodiments of the present invention provide a stove, a range hood, a range hood linkage system, a data transmission method for the stove, an air intake control method for the range hood, and a storage medium. The range hood according to the embodiment of the present invention has three air guide plates, which respectively open and close different air inlets. The stove has a temperature detection module, which can detect the temperature of the stove burner. Subsequently, the opening and closing of the three air guide plates can be controlled based on the temperature data of the burner. This air guide plate control scheme can flexibly, conveniently, and accurately adjust the air intake of the range hood, which is conducive to more timely and effective extraction of oil smoke.

[0063] Next, we will combine Figures 1 to 4 A cooker and a range hood according to an embodiment of the present invention are described. Figure 1 1 is a schematic block diagram of a cooker 100 according to an embodiment of the present invention. Figure 1The cooker 100 shown is only an example and is not intended to limit the present invention. Figure 1 For example, Figure 1 The cooker control device 130 is shown to be integrated into the pulse controller, but this is only an example, and the cooker control device 130 may be independent of the pulse controller. Figure 1 The temperature detection module 110 is shown to include a left temperature probe (ie, a first temperature probe) and a right temperature probe (ie, a second temperature probe), but the temperature detection module 110 may also include a smaller or larger number of temperature probes.

[0064] like Figure 1 As shown, the stove 100 includes a temperature detection module 110 and a stove communication module 120 .

[0065] The temperature detection module 110 is used to detect the temperatures of the first burner 210 and the second burner 220 on the stove 100 to obtain temperature data.

[0066] The temperature detection module 110 can be implemented by any suitable device capable of detecting temperature. For example, the temperature detection module 110 can be implemented by a temperature sensor such as a pressure thermometer, a resistance thermometer, a thermistor, a thermocouple, etc., such as a negative temperature coefficient (NTC) temperature sensor.

[0067] Exemplarily, the temperature detection module 110 can be set at any suitable position as long as it can detect the temperature of the first burner and the second burner. For example, the temperature detection module 110 can be set in the first burner and the second burner to detect the temperature of the bottom of the pot above the burner. It should be noted that the temperature of any burner refers to the temperature at a specific position within a predetermined distance (e.g., 10 cm) around the burner, and the specific position can be pre-set when the stove 100 is produced or installed, and is known to the stove control device 130 or the range hood control device 420. The temperature at the specific position can be determined by the stove control device 130 or the range hood control device 420 based on temperature data. It can be understood that when there is a pot above the burner, the temperature of any burner is the temperature in the pot above it.

[0068] Figure 2 A front view of a range hood and a stove according to an embodiment of the present invention is shown. Figure 3 FIG. 2 shows a left side view of a range hood and a stove according to an embodiment of the present invention. Figure 2 and Figure 3 Understand the positional relationship between the temperature detection module 110 and the burner of the stove.

[0069] The stove communication module 120 is used to transmit temperature data or an air deflector control signal generated based on the temperature data to the range hood 400, so that the range hood 400 controls the opening and closing of the air deflector in the air deflector assembly 430 of the range hood 400 based on the temperature data or the air deflector control signal, wherein the air deflector assembly 430 includes a first air deflector, a second air deflector, a third air deflector and a driving mechanism, and the driving mechanism is used to drive the first air deflector, the second air deflector and the third air deflector to independently open and close the first air inlet, the second air inlet and the third air inlet of the range hood, respectively, and the third air inlet is located between the first air inlet and the second air inlet.

[0070] The stove communication module 120 may be a wired communication module or a wireless communication module, which may be set as required.

[0071] The air inlet is closed when the air deflector is closed, and the air inlet is opened when the air deflector is opened. Optionally, the air deflector may be a plate capable of adjusting the air volume of the air inlet, for example, it may be a plate with adjustable angle and / or height, and the area of ​​the ventilated area of ​​the corresponding air inlet may be adjusted by changing the angle of the air deflector, or the distance between the corresponding air inlet and the air deflector may be adjusted by changing the height of the air deflector. In other words, when the air deflector is opened, it may be switched between a plurality of different angles and / or a plurality of different heights. Optionally, the air deflector may also be a plate having only two states, open and closed.

[0072] See also Figure 4 , a schematic block diagram of a range hood 400 according to an embodiment of the present invention is shown. The range hood 400 has a range hood control device 420, which is connected to the air deflector assembly 430. The range hood control device 420 can control the driving mechanism to drive each air deflector in the air deflector assembly 430 to open and close based on the temperature data or air deflector control signal received from the stove 100.

[0073] The range hood control device 420 may be any suitable device having data processing capability and / or instruction execution capability. For example, the range hood control device 420 may be implemented by a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), a microprocessor, a central processing unit (CPU), an application specific integrated circuit (ASIC), and other forms of processing units, or a combination of several of them.

[0074] Exemplarily, the driving mechanism of the range hood 400 may include an air guide plate motor ( Figure 4 (not shown), each air deflector motor can be used to drive the corresponding air deflector to move. Accordingly, the driving mechanism can also include a motor driving circuit ( Figure 4(not shown), the circuit can be used to output driving current to the first air guide plate motor of the first air guide plate, the second air guide plate motor of the second air guide plate and the third air guide plate motor of the third air guide plate, so as to drive each air guide plate motor to rotate, thereby driving each air guide plate to move.

[0075] Exemplarily, the range hood control device 420 can control the magnitude of the driving current output to each of the first air guide plate motor of the first air guide plate, the second air guide plate motor of the second air guide plate, and the third air guide plate motor of the third air guide plate to control the rotation of each air guide plate motor, and thereby control the opening and closing of each air guide plate.

[0076] Exemplarily, the range hood 400 may further include a fan, the fan including a main motor ( Figure 4 The range hood 400 includes a main motor (shown as a DC motor) and a fan, the main motor is used to drive the fan to rotate, thereby sucking out oil smoke. In addition, the range hood 400 may also include a motor drive circuit connected to the main motor, the motor drive circuit is used to output a drive current to the main motor to control the rotation of the main motor. Optionally, the range hood control device 420 may be connected to the motor drive circuit of the main motor, and the range hood control device 420 may also be used to control the size of the drive current output by the motor drive circuit, thereby controlling the speed of the fan (i.e., the working gear of the fan). An embodiment of the range hood control device 420 controlling the working gear of the fan will be described below.

[0077] After receiving the temperature data, the stove control device 130 or the range hood control device 420 can control the driving current corresponding to one or more of the first air guide plate, the second air guide plate and the third air guide plate based on the temperature data according to preset rules, thereby controlling the opening and closing of each air guide plate.

[0078] In one example, the cooker 100 may directly transmit the temperature data to the range hood 400, and the range hood 400 controls the air deflector assembly 430 based on the temperature data. In another example, the cooker 100 may process the temperature data, generate a corresponding air deflector control signal based on the temperature data, and transmit the signal to the range hood 400, and the range hood 400 may directly perform a corresponding operation based on the signal to control the air deflector assembly 430.

[0079] According to the range hood of the embodiment of the present invention, since the air guide plate assembly 430 includes three air guide plates, when the first air guide plate and / or the second air guide plate cannot effectively smoke in, the third air guide plate can be opened, that is, the third air inlet is opened to assist the first air inlet and / or the second air inlet to smoke in, so that the air intake can be effectively increased, so that the oil smoke can be quickly absorbed and the kitchen environment pollution can be reduced. This control scheme can quickly and flexibly adjust the air intake volume, effectively helping to absorb oil smoke. In addition, according to the embodiment of the present invention, the stove is provided with a temperature detection module, which can detect the temperature of the stove burner, and then the opening and closing of the three air guide plates can be controlled based on the detected temperature data. The temperature detection module is arranged on the stove, so that the detected temperature data can be more accurate, which helps to adjust the air intake volume more accurately.

[0080] According to an embodiment of the present invention, the stove 100 also includes a stove control device 130 connected to the temperature detection module 110 and the stove communication module 120 respectively. The stove control device 130 is used to receive temperature data collected by the temperature detection module 110 and transmit the temperature data or the air guide plate control signal to the stove communication module 120.

[0081] The stove control device 130 may be any suitable device having data processing capability and / or instruction execution capability. For example, the stove control device 130 may be implemented by a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), a microprocessor, a central processing unit (CPU), an application specific integrated circuit (ASIC), and other forms of processing units, or a combination of several of them.

[0082] By transferring or further processing the temperature data through the dedicated stove control device 130, the data processing efficiency at the stove end can be improved.

[0083] According to an embodiment of the present invention, the stove control device 130 is also used to: when a first condition is determined to be met based on temperature data, generate a first opening signal for controlling the opening of the third air guide plate, wherein the first condition is that the temperature of any one of the first burner 210 and the second burner 220 is greater than a first temperature threshold, and the air guide plate control signal includes the first opening signal.

[0084] The first temperature threshold may be any suitable value, which may be set as required, and the present invention is not limited thereto. For example, the first temperature threshold may be 100° C., 120° C., 150° C., 200° C., and the like.

[0085] Exemplarily, the first air guide plate and the second air guide plate can be regarded as corresponding to the first burner and the second burner, respectively, and the first air guide plate and the second air guide plate can be optionally opened according to the following rules: when the first burner is in use (for example, there is a pot above the first burner), the first air guide plate can be opened first, and the first air inlet can be mainly used for smoking; when the second burner is in use (for example, there is a pot above the second burner), the second air guide plate can be opened first, and the second air inlet can be mainly used for smoking.

[0086] The opening rule of the third air guide plate can be set as needed, and it can have multiple implementation schemes. In one embodiment, when the temperature of any one of the first burner and the second burner is greater than the first temperature threshold, the third air guide plate can be controlled to open. That is to say, in this embodiment, it is only necessary to check whether the temperature of any burner exceeds the threshold, and it is not necessary for the temperatures of the two burners to meet certain conditions at the same time. With this solution, when any burner is used, the third air inlet can be opened in time to increase the air intake, so that the oil smoke can be sucked in more cleanly.

[0087] For example, when the temperature of the first burner is greater than a certain threshold (i.e., the first temperature threshold), relying solely on the first air inlet to intake air may not be able to effectively absorb the fume, so you can choose to open the third air guide plate at this time. In this case, you do not need to consider the temperature of the second burner, that is, regardless of whether the second gas stove corresponding to the second burner is turned on or not, you can choose to open the third air guide plate. The processing method when the temperature of the second burner is greater than the first temperature threshold is similar and will not be repeated. Of course, if the temperatures of the first burner and the second burner are both greater than the first temperature threshold, the third air guide plate also needs to be opened.

[0088] It should be noted that, in the case where the air deflector has only two states, open and closed, the opening of a certain air deflector described herein may refer to placing the air deflector in the only open state. In the case where the angle and / or height of the air deflector are adjustable, the opening of a certain air deflector described herein may refer to opening the air deflector to a certain angle and / or height (hereinafter collectively described as an opening station), and the specific angle and / or height to which it is opened may optionally be determined based on temperature data.

[0089] According to an embodiment of the present invention, the stove control device 130 is also used to: when the third air deflector is open, when it is determined based on the temperature data that the first condition is not satisfied for a first preset time, generate a first closing signal for controlling the third air deflector to be closed, and the air deflector control signal includes the first closing signal.

[0090] The first preset time can be any suitable time, which can be set as needed, and the present invention is not limited to this. Exemplarily, the first preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the first preset time can be 0.

[0091] It can be understood that the state in which the temperatures of the first furnace head and the second furnace head are both less than or equal to the first temperature threshold is a state in which the first condition is not satisfied.

[0092] The following description is based on an example in which the first temperature threshold is 200°C and the first preset time is 30 seconds. When the temperature of the first burner exceeds 200°C, the third air guide plate is opened. Subsequently, the user may turn off the fire or reduce the fire power, so that the temperature of the first burner gradually decreases until it drops below 200°C. Subsequently, if it is determined that the temperature of the first burner has been below 200°C for more than 30 seconds, the third air guide plate may be closed.

[0093] When it is determined that the state in which the first condition is not satisfied continues for a first preset time, the third air guide plate is controlled to be closed. This solution can intelligently and automatically close the air guide plate in a timely manner, and the user experience is better.

[0094] According to an embodiment of the present invention, the stove control device 130 is also used to: when it is determined based on the temperature data that the second condition is met, generate a second opening signal for controlling the opening of the third air guide plate, wherein the second condition is that the temperature of any one of the first burner 210 and the second burner 220 is greater than the second temperature threshold and the temperature of the other of the first burner 210 and the second burner 220 is greater than the third temperature threshold, and the air guide plate control signal includes the second opening signal.

[0095] In this embodiment, it is necessary to check the temperatures of the two burners at the same time to ensure that the third air guide plate is opened only when the temperatures of the two burners are both greater than a certain threshold.

[0096] The second temperature threshold and the third temperature threshold can be any suitable value, which can be set as needed, and the present invention is not limited to this. Exemplarily, the second temperature threshold can be 100°C, 120°C, 150°C, 200°C, etc. Exemplarily, the third temperature threshold can be 100°C, 120°C, 150°C, 200°C, etc.

[0097] Exemplarily, the second temperature threshold and the third temperature threshold may be equal or unequal.

[0098] In one example, the second temperature threshold is 60° C. and the third temperature threshold is 200° C. That is, the third air guide plate can be opened only when the temperature of one of the first furnace head and the second furnace head is greater than 60° C. and the temperature of the other furnace head is greater than 200° C.

[0099] With this solution, the third air inlet is opened only when the two burners are in use and the temperature reaches a certain threshold to increase the air intake. This can save power to a certain extent and avoid frequent opening and closing of the third air guide plate when there is not much oil smoke.

[0100] According to an embodiment of the present invention, the stove control device 130 is also used to: when the third air deflector is open, when it is determined based on the temperature data that the second condition is not satisfied for a second preset time, generate a second closing signal for controlling the closing of the third air deflector, and the air deflector control signal includes the second closing signal.

[0101] The second preset time can be any suitable time, which can be set as needed, and the present invention is not limited to this. Exemplarily, the second preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the second preset time can be 0.

[0102] It can be understood that the state in which the temperature of any one of the first burner and the second burner is less than or equal to the smaller of the second temperature threshold and the third temperature threshold, or the temperature of both the first burner and the second burner is less than or equal to the larger of the second temperature threshold and the third temperature threshold, is that the second condition is not satisfied.

[0103] The following description is based on an example in which the second temperature threshold is 60°C, the third temperature threshold is 200°C, and the second preset time is 30 seconds. When the temperature of the first burner exceeds 60°C and the temperature of the second burner exceeds 200°C, the third air guide plate is opened. Subsequently, the user may turn off the fire or reduce the firepower, so that the temperature of the second burner gradually decreases until it drops below 200°C, while the temperature of the first burner remains at around 100°C. Subsequently, if it is determined that the temperatures of the first burner and the second burner are both below 200°C for more than 30 seconds, the third air guide plate can be closed.

[0104] When it is determined that the state in which the second condition is not satisfied continues for the second preset time, the third air guide plate is controlled to be closed. This solution can intelligently and automatically close the air guide plate in a timely manner, and the user experience is better.

[0105] According to an embodiment of the present invention, the stove control device 130 is also used to: when a third condition is determined to be satisfied based on temperature data, generate a third opening signal for controlling the opening of the third air guide plate, wherein the third condition is that the sum of the temperatures of the first burner 210 and the second burner 220 is greater than a fourth temperature threshold, and the air guide plate control signal includes the third opening signal.

[0106] In this embodiment, it is necessary to check the temperatures of the two furnace heads at the same time to ensure that the third air guide plate is opened only when the sum of the temperatures of the two furnace heads is greater than a certain threshold.

[0107] The fourth temperature threshold may be any suitable value, which may be set as required, and the present invention is not limited thereto. For example, the fourth temperature threshold may be 100° C., 120° C., 150° C., 200° C., and the like.

[0108] With this solution, the third air inlet is opened only when the sum of the temperatures of the two burners reaches a certain threshold to increase the air intake. This can save power to a certain extent and avoid frequent opening and closing of the third air guide plate when there is not much oil smoke.

[0109] According to an embodiment of the present invention, the stove control device 130 is also used to: when the third air guide plate is open, when it is determined based on the temperature data that the third condition is not satisfied for a third preset time, generate a third closing signal for controlling the third air guide plate to be closed, and the air guide plate control signal includes the third closing signal.

[0110] The third preset time can be any suitable time, which can be set as needed, and the present invention is not limited to this. Exemplarily, the third preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the third preset time can be 0.

[0111] It can be understood that the state in which the sum of the temperatures of the first furnace head and the second furnace head is less than or equal to the fourth temperature threshold value is a state in which the third condition is not satisfied.

[0112] When it is determined that the third air guide plate is not qualified to open and / or it is determined that the third condition is not satisfied for a third preset time, the driving mechanism is controlled to drive the third air guide plate to close. This solution can intelligently and automatically close the air guide plate in a timely manner, providing a better user experience.

[0113] According to an embodiment of the present invention, the stove control device 130 is also used to: when it is determined based on the temperature data that the fourth condition is met, generate a fourth opening signal for controlling the first air guide plate to open, wherein the fourth condition is that the temperature of the first burner 210 is greater than the fifth temperature threshold; and / or, when it is determined based on the temperature data that the fifth condition is met, generate a fifth opening signal for controlling the second air guide plate to open, wherein the fifth condition is that the temperature of the second burner 220 is greater than the fifth temperature threshold; wherein the air guide plate control signal includes the fourth opening signal and / or the fifth opening signal.

[0114] The fifth temperature threshold value may be any suitable value, which may be set as required, and the present invention is not limited thereto. Exemplarily, the fifth temperature threshold value may be 60°C, 80°C, 100°C, 120°C, and the like. Preferably, when the first burner and / or the second burner are used, the first air guide plate and / or the second air guide plate are opened preferentially, and when the air intake of the first air inlet and / or the second air inlet is insufficient, the third air guide plate is opened. Therefore, preferably, among the first temperature threshold value, the second temperature threshold value, the third temperature threshold value, and the fifth temperature threshold value, the fifth temperature threshold value is the smallest.

[0115] The first burner and the second burner correspond to the first air guide plate and the second air guide plate respectively, and the first air guide plate and the second air guide plate can be respectively controlled to be opened and closed according to the temperature of the first burner and the second burner, so that the oil smoke generated when the corresponding burners are used can be sucked through the first air inlet and the second air inlet. Compared with a single air inlet, the range hood including the first air inlet and the second air inlet can also effectively improve the smoke extraction effect.

[0116] According to an embodiment of the present invention, the stove control device 130 is also used to: when the first air deflector is open, when the state in which the fourth condition is not satisfied continues for a fourth preset time as determined based on the temperature data, generate a fourth closing signal for controlling the first air deflector to be closed; and / or, when the second air deflector is open, when the state in which the fifth condition is not satisfied continues for a fifth preset time as determined based on the temperature data, generate a fifth closing signal for controlling the second air deflector to be closed; wherein the air deflector control signal includes the fourth closing signal and / or the fifth closing signal.

[0117] The fourth preset time and the fifth preset time can be any suitable time, which can be set as needed, and the present invention is not limited thereto. Exemplarily, the fourth preset time or the fifth preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the fourth preset time or the fifth preset time can be 0.

[0118] The closing scheme of the first and second air guide plates and their advantages can be understood by referring to the above description of the embodiment of closing the third air guide plate, which will not be described in detail here.

[0119] According to an embodiment of the present invention, the fifth temperature threshold is lower than the first temperature threshold.

[0120] For example, the first temperature threshold may be 200°C, and the fifth temperature threshold may be 60°C. For example, when the user uses the first gas stove, the temperature of the first burner gradually rises, and when the temperature of the first burner exceeds 60°C, the first air guide plate is opened. If the user subsequently increases the firepower, such as using a high-fire mode, the temperature of the first burner may exceed 200°C, and the third air guide plate may be opened at this time. It is understood that when the temperature of the first burner exceeds 200°C, both the first and third air guide plates are opened.

[0121] According to this embodiment, the first air guide plate and / or the second air guide plate can be opened preferentially, and the third air guide plate can be used as an auxiliary when the air intake is insufficient. This working mode is a more targeted and reasonable oil fume absorption mode.

[0122] According to an embodiment of the present invention, the second temperature threshold is not equal to the third temperature threshold, and the fifth temperature threshold is less than or equal to the smaller one of the second temperature threshold and the third temperature threshold.

[0123] For example, the second temperature threshold and the fifth temperature threshold may be 60°C, and the third temperature threshold may be 200°C. For example, assuming that the user uses the first gas stove and the second gas stove at the same time, when the temperature of the first burner exceeds 60°C, the first air guide plate is opened, and when the temperature of the second burner also exceeds 60°C, the second air guide plate is opened. If the user adjusts the first gas stove to high fire mode and the second gas stove is still in low fire mode, the temperature of the first burner may exceed 200°C and the temperature of the second burner may exceed 60°C, and the third air guide plate may be opened at this time. It can be understood that when the temperature of the first burner exceeds 200°C and the temperature of the second burner exceeds 60°C, the first air guide plate, the second air guide plate and the third air guide plate are all opened.

[0124] It is possible that when both the first and second air guide plates are opened, the temperature of a burner still rises to a high level, so that the two air inlets cannot absorb clean oil smoke, so you can choose to open the third air guide plate. In other words, there is no need to wait until the temperatures of the two burners rise to a certain level before opening the third air guide plate, which can reduce the pollution caused by some stoves that are prone to produce oil smoke.

[0125] According to the embodiment of the present invention, the second temperature threshold is equal to the third temperature threshold, and the fifth temperature threshold is smaller than the second temperature threshold and the third temperature threshold.

[0126] For example, the fifth temperature threshold may be 60°C, and the second temperature threshold and the third temperature threshold may be 200°C. For example, assuming that the user uses the first gas stove and the second gas stove at the same time, when the temperature of the first burner exceeds 60°C, the first air guide plate is opened, and when the temperature of the second burner also exceeds 60°C, the second air guide plate is opened. If the user adjusts the first gas stove to high fire mode and the second gas stove is still in low fire mode, the temperature of the first burner may exceed 200°C and the temperature of the second burner may exceed 60°C, and the third air guide plate is not opened at this time. If the user adjusts both the first gas stove and the second gas stove to high fire mode, the temperature of both the first burner and the second burner may exceed 200°C, and the third air guide plate may be opened at this time. It can be understood that when the temperature of the first burner exceeds 200°C and the temperature of the second burner exceeds 200°C, the first air guide plate, the second air guide plate and the third air guide plate are all opened.

[0127] Sometimes the air intake of the first and second air inlets is large, which can meet the smoking needs relatively well most of the time. Only when the temperature of the two burners rises to a certain level (for example, the two gas stoves enter the stir-fry mode at the same time), the clean oil smoke may not be absorbed. At this time, the third air guide plate can be opened, so that the oil smoke can be absorbed in time while saving power consumption as much as possible.

[0128] According to an embodiment of the present invention, the stove control device 130 is also used to: generate a fan control signal for controlling the working gear of the fan of the range hood 400 based on the temperature data, and transmit the fan control signal to the range hood 400, so that the range hood 400 controls the working gear of the fan based on the fan control signal.

[0129] As described above, the range hood control device 420 can also be used to control the working gear of the fan by controlling the driving current of the main motor. The stove control device 130 can transmit the fan control signal to the range hood control device 420 via the communication module, and the range hood control device 420 performs the corresponding control operation.

[0130] The fan may have any number of working gears, for example, three working gears: high gear, medium gear, and low gear, and different working gears correspond to different fan speeds.

[0131] For example, as the temperature of any one or both burners increases, the working gear of the fan can be increased accordingly. This solution can further provide a larger air intake volume by adjusting the working gear of the fan, so as to absorb the oil smoke in time.

[0132] There are various rules for adjusting the working gear of the fan, and several exemplary implementation schemes are described below.

[0133] According to an embodiment of the present invention, the fan has multiple working gears corresponding to multiple temperature ranges, and the stove control device 130 is specifically used to: when it is determined based on the temperature data that the temperature of any one of the first burner 210 and the second burner 220 is less than the sixth temperature threshold and the temperature of the other of the first burner 210 and the second burner 220 falls into a specific temperature range among the multiple temperature ranges, generate a first gear signal for controlling the fan to operate at a working gear corresponding to the specific temperature range, and the fan control signal includes the first gear signal; when it is determined based on the temperature data that the temperature of any one of the first burner 210 and the second burner 220 falls into a first temperature range among the multiple temperature ranges and the temperature of the other of the first burner 210 and the second burner 220 falls into a second temperature range among the multiple temperature ranges, generate a second gear signal for controlling the fan to operate at a working gear corresponding to the first temperature range, the second temperature range, or any temperature range between the first temperature range and the second temperature range, and the fan control signal includes the second gear signal.

[0134] The sixth temperature threshold may be any suitable value, which may be set as required, and the present invention is not limited thereto. Exemplarily, the sixth temperature threshold may be 60°C, 80°C, 100°C, 120°C, and the like. In one example, the sixth temperature threshold is equal to the fifth temperature threshold, for example, the sixth temperature threshold and the fifth temperature threshold are both 60°C. In an embodiment where the sixth temperature threshold is equal to the fifth temperature threshold, when any burner is less than the sixth temperature threshold, the air guide plate corresponding to the burner is closed, and at this time, only the temperature of the other burner may be considered, and the corresponding working gear may be selected according to the temperature range into which the temperature of the other burner falls.

[0135] For example, it is assumed that the working gear of the fan is divided into three gears: low gear, medium gear and high gear, which correspond to the following three temperature ranges respectively: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C. In one example, when the temperature of the first burner is less than 60°C, the first air guide plate is not opened. At this time, if the temperature of the second burner is greater than or equal to 60°C and less than 150°C, the second air guide plate can be opened and the fan is controlled to work at the low gear at the same time. If the temperature of the second burner is greater than or equal to 150°C and less than 200°C, the second air guide plate can be opened and the fan is controlled to work at the medium gear at the same time. If the temperature of the second burner is greater than or equal to 200°C, the second air guide plate can be opened and the fan is controlled to work at the high gear at the same time.

[0136] In another example, when the temperature of the first burner is greater than or equal to 60°C and less than 150°C, and the temperature of the second burner is greater than or equal to 200°C, the first air guide plate and the second air guide plate can be opened, and the fan can be controlled to work at one of low, medium and high gears. Preferably, the working gear of the fan can be determined according to the temperature range into which the temperature of the burner with a higher temperature falls. For example, in the above example, the fan can be controlled to work at a high gear.

[0137] Through the above scheme, the working gear of the fan can be adjusted according to the rise and fall of the temperature of any one or two burners. At the same time, the air intake volume can be adjusted more flexibly by cooperating with the switch of the air guide plate.

[0138] According to an embodiment of the present invention, the first air guide plate has multiple first opening positions corresponding to multiple temperature ranges, and the stove control device 130 is also used to: when it is determined based on temperature data that the temperature of the first burner 210 falls into a specific temperature range among multiple temperature ranges, generate a first position signal for controlling the first air guide plate to open to a first opening position corresponding to the specific temperature range, and the air guide plate control signal includes the first position signal.

[0139] The first opening position may include an angle and / or height of the first air deflector. For example, the first air deflector and / or the second air deflector may be an air deflector that can be flipped between a flip open position and a flip closed position, and the air deflector is opened to different angles to adjust the area of ​​the ventilated area of ​​the air inlet. The third air deflector may be a lifting air deflector, and the air deflector can be lifted to different heights to adjust the distance between the air inlet and the air deflector.

[0140] Exemplarily, the first opening position may refer to the angle of the first air guide plate. For example, the first air guide plate may have three opening positions, i.e., three opening angles: a first angle, a second angle, and a third angle, which respectively correspond to the following three temperature ranges: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C.

[0141] In one example, if the temperature of the first burner is greater than or equal to 60°C and less than 150°C, the first air guide plate can be controlled to open to a first angle; if the temperature of the first burner is greater than or equal to 150°C and less than 200°C, the first air guide plate can be controlled to open to a second angle; if the temperature of the first burner is greater than or equal to 200°C, the first air guide plate can be controlled to open to a third angle.

[0142] Through the above scheme, the opening position of the first air guide plate can be adjusted as the temperature of the first furnace head rises or falls, so that the air intake volume can be adjusted more flexibly.

[0143] According to an embodiment of the present invention, the second air guide plate has multiple second opening positions corresponding to multiple temperature ranges, and the stove control device 130 is also used to: when it is determined based on temperature data that the temperature of the second burner 220 falls into a specific temperature range among multiple temperature ranges, generate a second position signal for controlling the second air guide plate to open to a second opening position corresponding to the specific temperature range, and the air guide plate control signal includes the second position signal.

[0144] The second opening position may include an angle and / or a height of the second air guide plate. As described above, the second air guide plate may be an air guide plate that can be flipped between a flip-open position and a flip-closed position.

[0145] For example, the second air guide plate can have three opening positions, i.e., three opening angles: a first angle, a second angle and a third angle, which correspond to the following three temperature ranges respectively: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C.

[0146] In one example, when the temperature of the second burner is greater than or equal to 60°C and less than 150°C, the second air guide plate can be controlled to open to a first angle; if the temperature of the second burner is greater than or equal to 150°C and less than 200°C, the second air guide plate can be controlled to open to a second angle; if the temperature of the second burner is greater than or equal to 200°C, the second air guide plate can be controlled to open to a third angle.

[0147] Through the above scheme, the opening position of the second air guide plate can be adjusted as the temperature of the second furnace head rises or falls, so that the air intake volume can be adjusted more flexibly.

[0148] According to an embodiment of the present invention, the temperature detection module 110 includes a first temperature probe and a second temperature probe. The first temperature probe is located around the first burner and is used to detect the temperature of the first burner. The second temperature probe is located around the second burner and is used to detect the temperature of the second burner.

[0149] The first temperature probe may be located within a first preset distance around the first burner, and the first preset distance may be set as needed, such as 5 cm, 10 cm, etc. The second temperature probe may be located within a second preset distance around the second burner, and the second preset distance may be set as needed, such as 5 cm, 10 cm, etc. Two temperature probes are used to detect the temperatures of the two burners respectively. Compared with a single temperature probe, this solution can detect and obtain more accurate temperature data.

[0150] According to an embodiment of the present invention, the cooker control device 130 is integrated on the pulse controller of the cooker. The configuration mode of integrating the cooker control device 130 on the pulse controller of the cooker can be adapted to conventional cookers, which is conducive to reducing development costs.

[0151] According to the embodiment of the present invention, the stove communication module 120 is a wireless communication module. Wireless communication is a low-cost and relatively stable transmission method, and wireless communication between the stove and the range hood can provide users with a better user experience.

[0152] According to another aspect of the present invention, a range hood is also provided. Figure 4 FIG. 4 is a schematic block diagram of a range hood 400 according to an embodiment of the present invention. Figure 4 The range hood 400 shown is only an example and is not intended to limit the present invention. Figure 4 For example, Figure 4 The range hood control device 420 is shown as a control chip, which includes a first chip 422 and a second chip 424 (to be described below), but the range hood control device 420 may also be a single chip or include a greater number of chips (e.g., three, etc.). Optionally, the range hood control device 420 may also be another type of device, such as a programmable logic controller (PLC). For another example, the range hood 400 may not be divided into a switch control board 440 and a power board 450, but all components may be implemented on the same circuit board. For another example, the light emitting diode display device ( Figure 4 The LED display (abbreviated as LED display) and buttons can be optional, that is, the range hood 400 can optionally include these components.

[0153] like Figure 4 As shown, the range hood 400 includes a range hood communication module 410 , a range hood control device 420 and an air guide plate assembly 430 .

[0154] The range hood communication module 410 is used to receive temperature data sent by the cooker 100 or an air guide plate control signal generated based on the temperature data. The temperature data is obtained by detecting the temperatures of the first burner and the second burner on the cooker 100 .

[0155] The range hood communication module 410 may be a wired communication module or a wireless communication module, which matches the stove communication module 120 .

[0156] The air guide assembly 430 includes a first air guide, a second air guide, a third air guide, and a driving mechanism, the driving mechanism is used to drive the first air guide, the second air guide, and the third air guide to independently open and close the first air inlet, the second air inlet, and the third air inlet of the range hood 400, respectively, and the third air inlet is located between the first air inlet and the second air inlet. Figure 2 and 4 In the figure, it is shown that the first air guide plate is the left air guide plate, the second air guide plate is the right air guide plate, and the third air guide plate is the middle air guide plate.

[0157] The range hood control device 420 is connected to the range hood communication module 410 and the driving mechanism respectively. The range hood control device 420 is used to receive temperature data or air guide plate control signals from the range hood communication module 410, and control the driving mechanism to drive each air guide plate to open and close based on the temperature data or the air guide plate control signals.

[0158] The driving and control principles of the air guide plate assembly 430 of the range hood have been described above and will not be repeated here.

[0159] According to the range hood of the embodiment of the present invention, since the air guide plate assembly 430 includes three air guide plates, when the first air guide plate and / or the second air guide plate cannot effectively smoke in, the third air guide plate can be opened, that is, the third air inlet is opened to assist the first air inlet and / or the second air inlet to smoke in, so that the air intake can be effectively increased, so that the oil smoke can be quickly absorbed and the kitchen environment pollution can be reduced. This control scheme can quickly and flexibly adjust the air intake volume, effectively helping to absorb oil smoke. In addition, according to the embodiment of the present invention, the stove is provided with a temperature detection module, which can detect the temperature of the stove burner, and then the opening and closing of the three air guide plates can be controlled based on the detected temperature data. The temperature detection module is arranged on the stove, so that the detected temperature data can be more accurate, which helps to adjust the air intake volume more accurately.

[0160] According to an embodiment of the present invention, the driving mechanism may include a lifting mechanism connected to the third air guide plate. The third air guide plate has a raised closed position and a lowered open position under the drive of the lifting mechanism. When the third air guide plate is in the raised closed position, the third air inlet is closed, and when the third air guide plate is in the lowered open position, the third air inlet is opened.

[0161] The lifting mechanism may be disposed inside the housing of the range hood and connected to the third air guide plate to drive the third air guide plate to rise and fall (i.e., close and open). The raised closed position of the third air guide plate refers to the position of the third air guide plate when the lifting mechanism is in the minimum telescopic state, at which the third air inlet is completely hidden relative to the outside of the range hood 400, and the third air inlet is closed. Conversely, the lowered open position of the third air guide plate refers to the position of the third air guide plate when the lifting mechanism is in the maximum telescopic state, at which the third air inlet is completely exposed relative to the outside of the range hood 400, and the third air inlet is open.

[0162] When a large amount of oil smoke appears in the kitchen, the lifting mechanism drives the third air guide plate to move to the lowered open position, and the third air inlet is opened. At this time, the oil smoke can enter the interior of the range hood 400 through the third air inlet, and then be discharged to the outside of the kitchen. When the kitchen oil smoke is reduced to a certain extent, the lifting mechanism drives the third air guide plate to move to the raised closed position, and the third air inlet is closed. At this time, the third air guide plate isolates the odor and residual oil smoke inside the range hood 400 from the kitchen environment.

[0163] The present invention can increase the area of ​​the air inlet by arranging the third air inlet between the first air inlet and the second air inlet. When the oil smoke generated by cooking is large, the third air inlet can be opened to quickly absorb the oil smoke, which can effectively protect the environmental sanitation of the kitchen and the health of users. The third air guide plate opens and closes the third air inlet by rising and falling. The third air inlet can be opened only when a large amount of oil smoke appears, and the third air inlet is kept closed at other times. In this way, the purpose of isolating the inside of the range hood from the outside and protecting the internal components of the range hood can be achieved.

[0164] According to an embodiment of the present invention, the driving mechanism may include a first flipping mechanism connected to the first air guide plate and a second flipping mechanism connected to the second air guide plate. The first air guide plate has a flip open position and a flip closed position when driven by the first flipping mechanism. When the first air guide plate is in the flip open position, the first air inlet is opened, and when the first air guide plate is in the flip closed position, the first air inlet is closed. The second air guide plate has a flip open position and a flip closed position when driven by the second flipping mechanism. When the second air guide plate is in the flip open position, the second air inlet is opened, and when the second air guide plate is in the flip closed position, the second air inlet is closed.

[0165] The first flipping mechanism may be disposed inside the housing of the range hood 400 and connected to the first air guide plate, so as to drive the first air guide plate to flip between a flip-open position and a flip-closed position. The second flipping mechanism may be disposed inside the housing of the range hood 400 and connected to the second air guide plate, so as to drive the second air guide plate to flip between a flip-open position and a flip-closed position. The flip-open position of the first air guide plate and the second air guide plate refers to the position of each air guide plate when the respective flipping mechanisms are at one end of the flipping stroke, at which time the corresponding air inlet is fully exposed relative to the outside of the range hood 400, and the corresponding air inlet is open. The flip-closed position of the first air guide plate and the second air guide plate refers to the position of each air guide plate when the respective flipping mechanisms are at the other end of the flipping stroke, at which time the corresponding air inlet is fully hidden relative to the outside of the range hood 400, and the corresponding air inlet is closed.

[0166] When oil smoke appears on the first side (for example, the left side), the first air guide plate is flipped open, and the first air inlet is opened. At this time, the oil smoke can enter the interior of the range hood 400 along the first air guide plate through the first air inlet, and then be discharged outside the kitchen. When the oil smoke on the first side disappears, the first air guide plate is flipped closed, so the first air inlet is closed, and the first air guide plate isolates the odor and residual oil smoke inside the range hood 400 and the flue from the kitchen environment. Similarly, when oil smoke appears on the second side (for example, the right side), the second air guide plate is flipped open, and the second air inlet is opened. At this time, the oil smoke can enter the interior of the range hood 400 along the second air guide plate through the second air inlet, and then be discharged outside the kitchen. When the oil smoke on the second side disappears, the second air guide plate is flipped closed, so the second air inlet is closed, and the second air guide plate isolates the odor and residual oil smoke inside the range hood 400 and the flue from the kitchen environment.

[0167] Through this flipping setting, the space occupied by the first air guide plate and the second air guide plate when they are opened can be reduced, thereby reducing the use space of the range hood 400, which helps to increase the user's activity space when cooking.

[0168] Exemplarily, each of the first flipping mechanism and the second flipping mechanism includes: a motor fixed in the housing of the range hood 400; a first transmission rod having a first end and a second end, the first end being connected to the rotating shaft of the motor; and a second transmission rod having a third end and a fourth end, the third end being pivotally connected to the second end, and the fourth end being pivotally connected to the corresponding first air guide plate or the second air guide plate.

[0169] For example, the first flip mechanism may include a motor, a first transmission rod and a second transmission rod. The motor is fixed inside the housing of the range hood 400. The first end of the first transmission rod is provided with a structure matching the rotating shaft of the motor, such as a hole, through which the first transmission rod is connected to the rotating shaft of the motor. The second end and the third end of the second transmission rod are provided with a matching structure, such as an axial hole, so that the first transmission rod and the second transmission rod can be pivotally connected together. The fourth end of the second transmission rod is provided with a matching structure, such as an axial hole, and the first air guide plate is pivotally connected together. Through this arrangement, the side wall of the range hood housing, the first transmission rod, the second transmission rod and the first air guide plate form a four-bar linkage, thereby realizing the function of the first air guide plate being turned over by the rotation of the rotating shaft of the motor through the first transmission rod and the second transmission rod. The structure and working principle of the second flip mechanism are similar and will not be repeated.

[0170] The flip mechanism implemented by the motor, the first transmission rod and the second transmission rod has a simple component structure, low processing cost, small weight and volume, which can effectively reduce the weight and manufacturing cost of the range hood 400 and simplify its internal structure.

[0171] Exemplarily, the lifting mechanism may include: a linear motor, which is fixed in the shell of the range hood 400; a slide rail, the slide rail having a fixed part and a sliding part, the fixed part is fixed in the shell of the range hood 400, and the sliding part is connected to the linear motor and the third air guide plate, and the linear motor drives the third air guide plate to rise and fall through the sliding part.

[0172] The lifting mechanism of the range hood 400 is provided with a linear motor and a slide rail. The linear motor is fixed inside the housing of the range hood 400 by a threaded connector. The slide rail can be similar to the slide rail used in a drawer. The slide rail includes a fixed part and a sliding part. The fixed part is fixed inside the housing of the range hood 400, for example, by a threaded connector. The sliding part can be connected to the linear motor and the third air guide plate. Exemplarily, one end of the sliding part can be provided with a structure matching the rotating shaft of the linear motor, such as a hole, through which the transmission shaft of the linear motor is connected. The other end of the sliding part can be fixed to the third air guide plate by three struts, and can be slidably connected to the fixed part by a slide groove or other forms. When the transmission shaft of the linear motor is extended, the sliding part is driven to move downward synchronously along the track of the fixed part, and the third air guide plate is driven to realize the function of landing through the three struts, thereby opening the third air inlet. Similarly, when the transmission shaft of the linear motor is retracted, the sliding part is driven to move upward synchronously along the track of the fixed part, and the third air guide plate is driven to realize the function of lifting through the three struts, thereby closing the third air inlet. Through this arrangement, the noise generated by the third air guide plate during the raising and lowering process can be effectively reduced, the resistance to movement can be reduced, and the power of the linear motor can be reduced, thereby achieving the purpose of energy saving and emission reduction.

[0184] According to the embodiment of the present invention, the range hood 400 may further include a fan, and the range hood control device 420 may further be used to control the working gear of the fan based on the temperature data.

[0185] According to an embodiment of the present invention, the fan has multiple working gears corresponding to multiple temperature ranges. The range hood control device 420 can be specifically used for: when it is determined based on the temperature data that the temperature of any one of the first burner and the second burner is less than the sixth temperature threshold and the temperature of the other of the first burner and the second burner falls into a specific temperature range among the multiple temperature ranges, the fan is controlled to operate in the working gear corresponding to the specific temperature range; when it is determined based on the temperature data that the temperature of any one of the first burner and the second burner falls into the first temperature range among the multiple temperature ranges and the temperature of the other of the first burner and the second burner falls into the second temperature range among the multiple temperature ranges, the fan is controlled to operate in the working gear corresponding to the first temperature range, the second temperature range, or any temperature range between the first temperature range and the second temperature range.

[0188] When describing the stove 100 above, various implementation schemes for controlling the air guide plate and the fan based on temperature data have been described. When implementing the scheme for controlling the air guide plate and the fan based on temperature data at the range hood 400, the principles and rules are similar and will not be repeated here.

[0189] According to an embodiment of the present invention, the range hood 400 may further include an input component for receiving air deflector indication information input by a user for indicating the opening and closing of air deflectors in the air deflector assembly 430. The range hood control device 420 is connected to the input component. The range hood control device 420 may also be used to control a driving mechanism to drive each air deflector to open and close based on the air deflector indication information.

[0190] Exemplarily, the input component may be any hardware capable of receiving user instructions, for example, it may include one or more of a keyboard, a mouse, a microphone, a touch screen, etc. Exemplarily, the input component may also be a wired or wireless communication component for receiving wind deflector indication information input by a user transmitted from an external device. The external device may be a personal computer, a mobile terminal, a server, etc.

[0191] For example, a plurality of air deflector control buttons, such as three air deflector control buttons, may be provided on the switch control panel of the range hood, and each of the three air deflector control buttons is used to control the opening and closing of the three air deflectors. For example, when a user presses the first air deflector control button, the first air deflector may be opened accordingly, and when the user presses the first air deflector control button again, the first air deflector may be closed accordingly.

[0192] An input component is provided for the user, so that the user can manually control the opening and closing of each air guide plate when necessary, so that the user can also have a greater degree of control freedom and a better user experience.

[0193] Exemplarily, the input component can also be used to receive mode indication information input by a user to indicate an automatic control mode, and the range hood control device 420 can also be used to receive temperature data or an air deflector control signal transmitted by the stove 100 in response to the reception of the mode indication information, and control the opening and closing of the air deflector in the air deflector assembly 430 based on the temperature data or the air deflector control signal.

For example, when the user presses the manual / automatic control button for the first time, the manual control mode is turned on, and the user can control the switch of each air deflector through the air deflector control button. When the user presses the manual / automatic control button again, the automatic mode is turned on, and the range hood control device 420 can start to read the temperature data and control the switch of each air deflector based on the temperature data.

[0195] According to the embodiment of the present invention, the range hood 400 may further include a switch control board 440 and a power board 450 , and the range hood control device 420 may be integrated on the power board 450 .

[0196] Return to see Figure 1 , showing a switch control panel 440 and a power panel 450. The switch control panel 440 can be arranged on the front of the range hood 400, and is mainly used for interacting with the user. For example, the user can input instructions through the buttons on the switch control panel 440 (such as the above-mentioned air guide plate control button, manual / automatic control button, etc.), and can also view information related to the range hood (such as the working gear of the fan, etc.) through the LED display device on the switch control panel 440.

[0197] The power board 450 can be arranged inside the housing of the range hood 400, and is mainly used to supply power to various components of the range hood. The power board 450 can include a power circuit and a motor drive circuit of the main motor, etc. The range hood control device 420 is integrated on the power board 450 to facilitate the control of the opening and closing of the air guide plate.

[0198] An exemplary air intake control method for oil smoke 400 is described below in conjunction with Table 1. Table 1 is a table of the correspondence between the burner temperature, the working gear of the fan and the switch state of the air guide plate. In the embodiment shown in Table 1, the working gear of the fan is divided into two gears, low gear and high gear, and the three air guide plates have only two states of open and closed. In Table 1, the left temperature refers to the temperature of the left burner (i.e., the first burner), and the right temperature refers to the temperature of the right burner (i.e., the second burner). Observing Table 1, it can be seen that when the temperature of the left burner or the right burner is greater than 60°C, the corresponding left air guide plate or right air guide plate is opened (see the above embodiment related to the fifth temperature threshold). The middle air guide plate is only opened when the temperature of the left burner and the right burner is greater than 60°C and the temperature of the other is greater than 200°C (see the above embodiment related to the second temperature threshold and the third temperature threshold). When only one burner is used (the temperature of the other burner does not exceed 60°C), the fan selects the working gear based on the temperature range of the burner, and uses the low gear when the temperature does not exceed 200°C, and uses the high gear when the temperature exceeds 200°C (see the above embodiment related to the sixth temperature threshold). When two burners are used (the temperature of both burners exceeds 60°C), the fan uses the high gear only when the temperature of both burners exceeds 200°C, and uses the low gear in other cases.

[0204] In step S510 , the temperatures of the first burner 210 and the second burner 220 on the cooker 100 are detected to obtain temperature data.

[0205] In step S520, the temperature data or the air deflector control signal generated based on the temperature data is transmitted to the range hood 400, so that the range hood 400 controls the opening and closing of the air deflector in the air deflector assembly 430 of the range hood 400 based on the temperature data or the air deflector control signal, wherein the air deflector assembly 430 includes a first air deflector, a second air deflector, a third air deflector and a driving mechanism, and the driving mechanism is used to drive the first air deflector, the second air deflector and the third air deflector to independently open and close the first air inlet, the second air inlet and the third air inlet of the range hood 400, respectively, and the third air inlet is located between the first air inlet and the second air inlet.
