Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the invention.

In order to at least partially solve the technical problems, embodiments of the present invention provide a cooker, a range hood, a smoke range linkage system, a data transmission method for a cooker, an air intake control method for a range hood, and a storage medium. The range hood provided by the embodiment of the invention is provided with the three air deflectors which are used for respectively opening and closing different air inlets, the stove is provided with the temperature detection module which can detect the temperature of the stove head of the stove, and then the opening and closing of the three air deflectors can be controlled based on the temperature data of the stove head.

Hereinafter, a cooktop and a range hood according to an embodiment of the present invention will be described with reference to fig. 1 to 4. Fig. 1 shows a schematic block diagram of a hob 100 according to an embodiment of the present invention. It is noted that the cooktop 100 shown in fig. 1 is merely an example and not a limitation of the present invention, and the present invention is not limited to the embodiment shown in fig. 1. For example, fig. 1 shows the cooktop control 130 integrated in the pulse controller, but this is merely an example, and the cooktop control 130 may be independent of the pulse controller. For another example, fig. 1 shows that the temperature detection module 110 includes a left temperature probe (i.e., a first temperature probe) and a right temperature probe (i.e., a second temperature probe), but the temperature detection module 110 may include a smaller or larger number of temperature probes.

As shown in fig. 1, the cooktop 100 includes a temperature detection module 110 and a cooktop communication module 120.

The temperature detection module 110 is used for detecting the temperature of the first furnace head 210 and the second furnace head 220 on the cooker 100 to obtain temperature data.

The temperature detection module 110 may be implemented using any suitable device capable of detecting temperature. For example, the temperature detection module 110 may be implemented using a temperature sensor of the pressure thermometer, resistance thermometer, thermistor, thermocouple, etc., for example, a Negative Temperature Coefficient (NTC) temperature sensor.

For example, the temperature detection module 110 may be disposed at any suitable position as long as it can detect the temperatures of the first and second furnace ends. For example, the temperature detection module 110 may be provided in the first and second oven heads for detecting the temperature of the bottom of the pot above the oven heads. It is noted that the temperature of any burner refers to the temperature at a specific location within a predetermined distance (e.g., 10 centimeters) around the burner, which may be pre-set at the time of production or installation of the cooktop 100, known to the cooktop control 130 or range hood control 420. The temperature at the particular location may be determined by the cooktop control 130 or range hood control 420 based on the temperature data. It will be appreciated that in the case of a pan above the burner, the temperature of any burner is the temperature in the pan above it.

Figure 2 shows a front view of a range hood and a hob according to one embodiment of the invention. Figure 3 shows a left side view of a range hood and a cooktop according to one embodiment of the invention. The positional relationship of the temperature detection module 110 and the burner of the hob can be understood with reference to fig. 2 and 3.

The cooker communication module 120 is configured to transmit the 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 opening and closing of an air deflector in an air deflector assembly 430 of the range hood 400 based on the temperature data or the air deflector control signal, where the air deflector assembly 430 includes a first air deflector, a second air deflector, a third air deflector, and a driving mechanism, the driving mechanism is configured to drive the first air deflector, the second air deflector, and the third air deflector to independently open and close a first air inlet, a second air inlet, and a 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.

The cooktop communication module 120 can be a wired communication module or a wireless communication module, which can be set as desired.

The air inlet is closed when the air deflector is closed, and the air inlet is opened when the air deflector is opened. Alternatively, the air deflector may be a plate capable of adjusting the air intake amount of the air inlet, for example, it may be an angle and/or height adjustable plate, the area of the ventable region of the air inlet corresponding to the air deflector may be adjusted by changing the angle of the air deflector, or the distance between the air inlet corresponding to the air deflector and the air deflector may be adjusted by changing the height of the air deflector. That is, the deflector, when open, may be switched between a plurality of different angles and/or a plurality of different heights. Alternatively, the air deflection plate may be a plate having only two states of opening and closing.

Referring to fig. 4, a schematic block diagram of a range hood 400 according to one embodiment of the present invention is shown. The range hood 400 has a range hood control device 420 connected to the air deflector assembly 430, and the range hood control device 420 may control the driving mechanism to drive each air deflector in the air deflector assembly 430 to open and close based on temperature data or an air deflector control signal received from the cooker 100.

Range hood control device 420 may be any suitable device having data processing capabilities and/or instruction execution capabilities. For example, the smoke ventilator control device 420 may be implemented using one or a combination of Programmable Logic Controllers (PLCs), Digital Signal Processors (DSPs), Field Programmable Gate Arrays (FPGAs), Programmable Logic Arrays (PLAs), microprocessors, Central Processing Units (CPUs), Application Specific Integrated Circuits (ASICs), and other forms of processing units.

For example, the driving mechanism of the range hood 400 may include a wind deflector motor (not shown in fig. 4) corresponding to the three wind deflectors one to one, and each wind deflector motor may be configured to drive the corresponding wind deflector to move. Correspondingly, the driving mechanism may further include a motor driving circuit (not shown in fig. 4) associated with the air deflectors, and the motor driving circuit may be configured to output a driving current to the first air deflector motor of the first air deflector, the second air deflector motor of the second air deflector, and the third air deflector motor of the third air deflector, so as to drive the respective air deflector motors to rotate, and further drive the respective air deflectors to move.

For example, the range hood control device 420 may control the magnitude of the driving current output to each of the first air deflection motor of the first air deflection, the second air deflection motor of the second air deflection, and the third air deflection motor of the third air deflection to control the rotation of each air deflection motor, thereby controlling the opening and closing of each air deflection.

Illustratively, the range hood 400 may further include a fan including a general motor (shown as a dc motor in fig. 4) for driving the fan to rotate, thereby sucking the soot. In addition, the range hood 400 may further include a motor driving circuit connected to the main motor, the motor driving circuit being configured to output a driving current to the main motor to control the main motor to rotate. Optionally, the range hood control device 420 may be connected to a motor driving circuit of the main motor, and the range hood control device 420 may also be configured to control a magnitude of a driving current output by the motor driving circuit, so as to control a rotation speed of the fan (i.e., a working gear of the fan). An embodiment in which the range hood control device 420 controls the operating range of the fan will be described below.

After the cooker control device 130 or the range hood control device 420 receives the temperature data, the driving current corresponding to one or more of the first air deflector, the second air deflector and the third air deflector can be controlled based on the temperature data according to a preset rule, so as to control the opening and closing of each air deflector.

In one example, the cooktop 100 can directly transmit temperature data to the range hood 400, with the range hood 400 controlling the air deflection assemblies 430 based on the temperature data. In another example, the cooktop 100 can process 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 can directly perform a corresponding operation based on the signal to achieve control of the air deflector assembly 430.

According to the range hood disclosed by the embodiment of the invention, as the air deflector assembly 430 comprises the three air deflectors, when the first air deflector and/or the second air deflector cannot effectively smoke, the third air deflector can be opened, namely the third air inlet is opened to assist the first air inlet and/or the second air inlet in smoking, so that the air inlet amount can be effectively increased, oil smoke can be quickly sucked, and the environmental pollution of a kitchen is reduced. The control scheme can quickly and flexibly adjust the air inlet volume and effectively help to absorb the oil smoke. In addition, according to the embodiment of the invention, the stove is provided with a temperature detection module, the temperature of the stove head of the stove can be detected, and then the opening and the closing of the three air deflectors can be controlled based on the detected temperature data. The temperature detection module is arranged on the cooker, so that the detected temperature data can be more accurate, and the air inlet volume can be adjusted more accurately.

According to the embodiment of the present invention, the cooker 100 further includes a cooker control device 130 respectively connected to the temperature detection module 110 and the cooker communication module 120, and the cooker control device 130 is configured to receive temperature data collected by the temperature detection module 110 and transmit the temperature data or an air deflector control signal to the cooker communication module 120.

The cooktop control 130 can be any suitable device having data processing capabilities and/or instruction execution capabilities. For example, the cooker control device 130 may be implemented using one or a combination of several of 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.

The data processing efficiency at one end of the cooker can be improved by transferring or further processing the temperature data through the special cooker control device 130.

According to an embodiment of the invention, the hob control device 130 is further configured to: and when it is determined that a first condition is met based on the temperature data, generating a first opening signal for controlling the third air deflector to open, wherein the first condition is that the temperature of any one of the first furnace head 210 and the second furnace head 220 is greater than a first temperature threshold value, and the air deflector control signal comprises the first opening signal.

The first temperature threshold may be any suitable value, which may be set as desired, and the invention is not limited thereto. Illustratively, the first temperature threshold may be 100 ℃, 120 ℃, 150 ℃, 200 ℃, and so on.

For example, the first air deflector and the second air deflector may be considered to correspond to the first burner and the second burner, respectively, and the first air deflector and the second air deflector may optionally open according to the following rules: when the first furnace end is used (for example, a pot is arranged above the first furnace end), the first air deflector can be opened firstly, the first air inlet is mainly used for smoking, and when the second furnace end is used (for example, a pot is arranged above the second furnace end), the second air deflector can be opened firstly, the second air inlet is mainly used for smoking.

The opening rule of the third air deflector can be set according to requirements, and the third air deflector can have various implementation schemes. In one embodiment, when the temperature of any one of the first furnace end and the second furnace end is greater than the first temperature threshold, the third air deflector can be controlled to be opened. That is to say, in this embodiment, only need look over whether the temperature of arbitrary furnace end exceeds the threshold value can, need not the temperature of two furnace ends and satisfies certain condition simultaneously. By adopting the scheme, when any burner is used, the third air inlet can be opened in time to increase the air inlet amount, so that the oil smoke can be sucked more cleanly.

For example, when the temperature of the first stove head is greater than a certain threshold (i.e., the first temperature threshold), the oil smoke may not be effectively sucked only by the first air inlet, and therefore the third air deflector may be selectively opened at this time. In this case, the third air guiding plate can be selectively opened regardless of the temperature of the second burner, i.e., whether the second gas stove corresponding to the second burner is on or not. The processing mode when the temperature of the second furnace end is greater than the first temperature threshold value is similar, and the description is omitted. Of course, if the temperatures of the first and second burners are simultaneously greater than the first temperature threshold, the third air deflector also needs to be opened.

It should be noted that in the case of a deflector having only two states, open and closed, opening a deflector as described herein may refer to placing the deflector in a single open state. Where the angle and/or height of the deflector is adjustable, opening a deflector as described herein can be opening the deflector to an angle and/or height (described collectively below with an opening station), and the specific angle and/or height to which the deflector is opened can optionally be determined based on temperature data.

According to an embodiment of the invention, the hob control device 130 is further configured to: and under the condition that the third air deflector is opened, when the state that the first condition is not satisfied is determined to continue for the first preset time based on the temperature data, generating a first closing signal for controlling the third air deflector to be closed, wherein the air deflector control signal comprises the first closing signal.

The first preset time may be any suitable time, which may be set according to needs, and the present invention is not limited thereto. Illustratively, the first preset time may be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, and so on. Of course, alternatively, the first preset time may be 0.

It is understood that the state in which the temperatures of the first and second burners are both less than or equal to the first temperature threshold belongs to the state in which the first condition is not satisfied.

The following description will be given taking the example where the first temperature threshold is 200 deg.c and the first preset time is 30 seconds. When the temperature of the first furnace end exceeds 200 ℃, the third air deflector is opened at the moment. Subsequently, the user may shut down or reduce the fire power so that the temperature of the first burner is gradually lowered down to below 200 ℃. Subsequently, if it is determined that the state in which the temperature of the first head is below 200 ℃ continues for more than 30 seconds, the third air guide plate may be turned off.

When the situation that the first condition is not satisfied is determined to continue for the first preset time, the third air deflector is controlled to be closed, the scheme can intelligently and automatically close the air deflectors in time, and user experience is good.

According to an embodiment of the invention, the hob control device 130 is further configured to: and generating a second opening signal for controlling a third air deflector to open when it is determined based on the temperature data that a second condition is met, wherein the second condition is that the temperature of any one of the first furnace head 210 and the second furnace head 220 is greater than a second temperature threshold and the temperature of the other one of the first furnace head 210 and the second furnace head 220 is greater than a third temperature threshold, and the air deflector control signal comprises the second opening signal.

In this embodiment, the temperature of two burners need to be checked simultaneously, and the third air deflector is opened only when the temperature of two burners is greater than a certain threshold value.

The second temperature threshold and the third temperature threshold may be any suitable values, which may be set according to needs, and the invention is not limited thereto. Illustratively, the second temperature threshold may be 100 ℃, 120 ℃, 150 ℃, 200 ℃, and so on. Illustratively, the third temperature threshold may be 100 ℃, 120 ℃, 150 ℃, 200 ℃, and so on.

For example, the second temperature threshold and the third temperature threshold may be equal or unequal.

In one example, the second temperature threshold is 60 ℃ and the third temperature threshold is 200 ℃. That is, in the first and second burners, the third air guide plate may be opened when the temperature of one burner is higher than 60 ℃ and the temperature of the other burner is higher than 200 ℃.

By adopting the scheme, the third air inlet is opened when the two burner heads are used and the temperature reaches a certain threshold value, so that the air inlet amount is increased, the power can be saved to a certain extent, and the third air deflector is prevented from being frequently opened and closed when the oil smoke is not much.

According to an embodiment of the invention, the hob control device 130 is further configured to: and under the condition that the third air deflector is opened, when the state that the second condition is not satisfied is determined to continue for the second preset time based on the temperature data, generating a second closing signal for controlling the third air deflector to be closed, wherein the air deflector control signal comprises the second closing signal.

The second preset time may be any suitable time, which may be set according to needs, and the present invention is not limited thereto. Illustratively, the second preset time may be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, and so on. Of course, alternatively, the second preset time may be 0.

It is to be understood that the state where the temperature of either one of the first and second burners is less than or equal to the smaller of the second and third temperature thresholds, or the temperature of both the first and second burners is less than or equal to the larger of the second and third temperature thresholds is a state where the second condition is not satisfied.

The following description will be given by taking the example that 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 furnace end exceeds 60 ℃ and the temperature of the second furnace end exceeds 200 ℃, the third air deflector is opened at the moment. Subsequently, the user may shut down or reduce the fire power so that the temperature of the second burner is gradually lowered down to below 200 ℃ while the temperature of the first burner is kept constant above or below 100 ℃. Subsequently, if it is determined that the temperatures of the first and second burners are simultaneously in the state below 200 ℃ for more than 30 seconds, the third air guide plate may be turned off.

When the situation that the second condition is not satisfied is determined to continue for the second preset time, the third air deflector is controlled to be closed, the scheme can intelligently and automatically close the air deflector in time, and user experience is good.

According to an embodiment of the invention, the hob control device 130 is further configured to: generating a third opening signal for controlling a third air deflector to open when it is determined based on the temperature data that a third condition is satisfied, wherein the third condition is that a sum of the temperatures of the first and

second burners

210 and 220 is greater than a fourth temperature threshold, the air deflector control signal comprising the third opening signal.

In this embodiment, the temperatures of the two burners need to be checked at the same time, and the third air deflector is opened only when the sum of the temperatures of the two burners is greater than a certain threshold.

The fourth temperature threshold may be any suitable value, which may be set as desired, and the invention is not limited thereto. Illustratively, the fourth temperature threshold may be 100 ℃, 120 ℃, 150 ℃, 200 ℃, and so on.

By adopting the scheme, when the sum of the temperatures of the two furnace ends reaches a certain threshold value, the third air inlet is opened, the air inlet amount is increased, so that the power can be saved to a certain extent, and the third air deflector is prevented from being frequently opened and closed when the oil smoke is not too much.

According to an embodiment of the invention, the hob control device 130 is further configured to: and under the condition that the third air deflector is opened, when the state that the third condition is not satisfied is determined to continue for a third preset time based on the temperature data, generating a third closing signal for controlling the third air deflector to be closed, wherein the air deflector control signal comprises the third closing signal.

The third preset time may be any suitable time, which may be set according to needs, and the present invention is not limited thereto. Illustratively, the third preset time may be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, and so on. Of course, alternatively, the third preset time may be 0.

It is understood that a state in which the sum of the temperatures of the first and second burners is less than or equal to the fourth temperature threshold value belongs to a state in which the third condition is not satisfied.

When the third air deflector is determined to be in the state of being unqualified to be opened and/or the state of being unsatisfied by the third condition is determined to last for the third preset time, the driving mechanism is controlled to drive the third air deflector to be closed, the scheme can intelligently and automatically close the air deflector in time, and user experience is good.

According to an embodiment of the invention, the hob control device 130 is further configured to: generating a fourth opening signal for controlling the first air deflector to open when it is determined based on the temperature data that a fourth condition is satisfied, wherein the fourth condition is that the temperature of the first furnace head 210 is greater than a fifth temperature threshold; and/or generating a fifth opening signal for controlling the second air deflector to open when it is determined based on the temperature data that a fifth condition is satisfied, wherein the fifth condition is that the temperature of the second burner 220 is greater than a fifth temperature threshold; the air deflector control signal comprises a fourth opening signal and/or a fifth opening signal.

The fifth temperature threshold may be any suitable value, which may be set as desired, and the invention is not limited thereto. Illustratively, the fifth temperature threshold may be 60 ℃, 80 ℃, 100 ℃, 120 ℃, and so on. Preferably, when the first furnace end and/or the second furnace end is/are used, the first air deflector and/or the second air deflector is/are opened preferentially, and when the air intake of the first air inlet and/or the second air inlet is/are insufficient, the third air deflector is opened. Therefore, it is preferable that the fifth temperature threshold value is the smallest among the above-described first temperature threshold value, second temperature threshold value, third temperature threshold value, and fifth temperature threshold value.

The first furnace end and the second furnace end respectively correspond to the first air deflector and the second air deflector, and the first air deflector and the second air deflector can be respectively controlled to be opened and closed according to the temperatures of the first furnace end and the second furnace end, so that oil smoke generated when the respectively corresponding furnace ends are used can be sucked through the first air inlet and the second air inlet. Compared with a single air inlet, the range hood comprising the first air inlet and the second air inlet can effectively improve the smoking effect.

According to an embodiment of the invention, the hob control device 130 is further configured to: when the first air deflector is opened, generating a fourth closing signal for controlling the first air deflector to close when the fourth condition unsatisfied state is determined to continue for a fourth preset time based on the temperature data; and/or, in the case that the second air deflector is opened, generating a fifth closing signal for controlling the second air deflector to close when it is determined that the fifth condition is not satisfied for a fifth preset time based on the temperature data; the air deflector control signal comprises a fourth closing signal and/or a fifth closing signal.

The fourth preset time and the fifth preset time may be any suitable time, which may be set as needed, and the present invention is not limited thereto. Illustratively, the fourth preset time or the fifth preset time may be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, and the like. Of course, alternatively, the fourth preset time or the fifth preset time may be 0.

The closing schemes of the first air guiding plate and the second air guiding plate and the advantages thereof can be understood by referring to the above description of the embodiment of closing the third air guiding plate, and the detailed description thereof is omitted.

According to an embodiment of the invention, the fifth temperature threshold is smaller than the first temperature threshold.

For example, the first temperature threshold may be 200 ℃ and the fifth temperature threshold may be 60 ℃. For example, when the user uses the first gas stove, the temperature of the first stove head is gradually increased, and when the temperature of the first stove head exceeds 60 ℃, the first air deflector is opened. The third air deflection plate may then be opened if the user increases the fire, for example using a high fire mode, which may result in the temperature of the first head exceeding 200 ℃. It can be understood that when the temperature of the first furnace head exceeds 200 ℃, the first air deflector and the third air deflector are both opened.

According to the embodiment, the first air guide plate and/or the second air guide plate can be opened preferentially, the third air guide plate is used as an auxiliary when the air intake is insufficient, and the working mode is a targeted and reasonable oil smoke suction mode.

According to an embodiment of the 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 of the second temperature threshold and the third temperature threshold.

For example, the second and fifth temperature thresholds may be 60 ℃ and the third temperature threshold may be 200 ℃. For example, if a user uses a first gas stove and a second gas stove at the same time, the first air deflector is opened when the temperature of the first burner exceeds 60 ℃, and the second air deflector is opened when the temperature of the second burner also exceeds 60 ℃. If the user adjusts the first gas range to the high fire mode, and the second gas range to the low fire mode, it is likely that the temperature of the first burner will exceed 200 deg.c, the temperature of the second burner will exceed 60 deg.c, and the third air guide plate may be opened at this time. It can be understood that when the temperature of the first furnace end exceeds 200 ℃ and the temperature of the second furnace end exceeds 60 ℃, the first air deflector, the second air deflector and the third air deflector are all opened.

Possibly, under the condition that the first air deflector and the second air deflector are both opened, the temperature of a certain burner is still raised to be higher, so that the two air inlets cannot suck clean oil smoke, and therefore the third air deflector can be selectively opened. That is to say, the third air deflector does not need to be opened until the temperatures of the two furnace ends are raised to a certain degree, so that pollution caused by certain cookers which are easy to generate oil smoke can be reduced.

According to an embodiment of the 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.

For example, the fifth temperature threshold may be 60 ℃ and the second and third temperature thresholds may be 200 ℃. For example, if a user uses a first gas stove and a second gas stove at the same time, the first air deflector is opened when the temperature of the first burner exceeds 60 ℃, and the second air deflector is opened when the temperature of the second burner also exceeds 60 ℃. If the user adjusts the first gas range to the high fire mode, and the second gas range is also in the low fire mode, it is likely that the temperature of the first burner will exceed 200 ℃, the temperature of the second burner will exceed 60 ℃, and the third air deflector is not opened at this time. If the user adjusts both the first gas range and the second gas range to the high fire mode, it is likely that the temperatures of both the first burner and the second burner will exceed 200 ℃, and at this time, the third air guide plate may be opened. It can be understood that when the temperature of the first furnace end exceeds 200 ℃, and the temperature of the second furnace end exceeds 200 ℃, the first air deflector, the second air deflector and the third air deflector are all opened.

Sometimes, the air inlet volume of the first air inlet and the second air inlet is large, the requirement for smoking can be met well in most of time, only when the temperatures of the two burner heads are raised to a certain degree (for example, the two gas stoves enter a stir-frying mode at the same time), clean oil smoke can not be sucked, then the third air deflector can be opened, and the oil smoke can be sucked timely while the power consumption is saved as much as possible.

According to an embodiment of the invention, the hob control device 130 is further configured to: a fan control signal for controlling a working gear of a fan of the range hood 400 is generated based on the temperature data, and the fan control signal is transmitted to the range hood 400 to control the working gear of the fan by the range hood 400 based on the fan control signal.

As described above, the range hood control device 420 may also be used to control the operating range of the fan by controlling the driving current of the overall motor. The cooker control device 130 may transmit a fan control signal to the range hood control device 420 via the communication module, and the range hood control device 420 performs a corresponding control operation.

The fan may have any number of operating positions, for example three: high-grade, medium-grade, low-grade, different working gear correspond to different fan rotational speeds.

Illustratively, as the temperature of either or both of the furnace ends is increased, the working gear of the fan can be correspondingly increased. The scheme can further provide larger air inlet amount by adjusting the working gear of the fan and absorb oil smoke in time.

There are various adjustment rules for the operating range of the wind turbine, and several exemplary implementations will be described below.

According to an embodiment of the present invention, the fan has a plurality of working gears corresponding to a plurality of temperature ranges one to one, and the cooker control device 130 is specifically configured to: when it is determined that the temperature of any one of the first furnace end 210 and the second furnace end 220 is less than the sixth temperature threshold based on the temperature data and the temperature of the other one of the first furnace end 210 and the second furnace end 220 falls within a specific temperature range of the plurality of temperature ranges, generating a first gear signal for controlling the fan to operate in an operating gear corresponding to the specific temperature range, the fan control signal including the first gear signal; when it is determined based on the temperature data that the temperature of any one of the first and second furnace heads 210 and 220 falls within a first temperature range of the plurality of temperature ranges and the temperature of the other one of the first and second furnace heads 210 and 220 falls within a second temperature range of the plurality of temperature ranges, a second gear signal for controlling the fan to operate at an operating gear corresponding to the first temperature range, or the second temperature range, or any temperature range between the first and second temperature ranges is generated, the fan control signal including the second gear signal.

The sixth temperature threshold may be any suitable value, which may be set as desired, and the invention is not limited thereto. Illustratively, the sixth temperature threshold may be 60 ℃, 80 ℃, 100 ℃, 120 ℃, and so on. In one example, the sixth temperature threshold is equal to the fifth temperature threshold, e.g., the sixth temperature threshold and the fifth temperature threshold are both 60 ℃. In an embodiment where the sixth temperature threshold is equal to the fifth temperature threshold, when any one of the furnace ends is smaller than the sixth temperature threshold, the air deflector corresponding to the furnace end is closed, and at this time, the corresponding operating gear may be selected according to a temperature range in which the temperature of the other furnace end falls, by only considering the temperature of the other furnace end.

For example, suppose the working gear of the fan is divided into three gears: low, medium and high gears, corresponding to the following three temperature ranges respectively: greater than or equal to 60 ℃ and less than 150 ℃, greater than or equal to 150 ℃ and less than 200 ℃, greater than or equal to 200 ℃. In one example, when the temperature of the first furnace end is less than 60 ℃, the first air deflector is not opened, and at this time, if the temperature of the second furnace end is greater than or equal to 60 ℃ and less than 150 ℃, the second air deflector can be opened and the fan can be controlled to operate at a low gear at the same time, if the temperature of the second furnace end is greater than or equal to 150 ℃ and less than 200 ℃, the second air deflector can be opened and the fan can be controlled to operate at a medium gear at the same time, and if the temperature of the second furnace end is greater than or equal to 200 ℃, the second air deflector can be opened and the fan can be controlled to operate at a high gear at the same time.

In another example, when the temperature of the first burner is greater than or equal to 60 ℃ and less than 150 ℃, and the temperature of the second burner is greater than or equal to 200 ℃, the first air deflector and the second air deflector may be opened, and the fan may be controlled to operate in one of a low range, a medium range, and a high range. Preferably, the working gear of the fan can be determined according to the temperature range in which the temperature of the furnace end with higher temperature falls. For example, in the above example, the fan may be controlled to operate in a high range.

Through above scheme, can adjust the work gear of fan along with the lift of the temperature of arbitrary or two furnace ends, the switch of cooperation aviation baffle simultaneously can adjust the intake more in a flexible way.

According to an embodiment of the present invention, the first air guiding plate has a plurality of first opening stations corresponding to a plurality of temperature ranges one to one, and the cooker control device 130 is further configured to: when it is determined based on the temperature data that the temperature of the first furnace head 210 falls within a specific temperature range of the plurality of temperature ranges, a first station signal for controlling the first air deflector to open to a first open station corresponding to the specific temperature range is generated, the air deflector control signal including the first station signal.

The first opening station may comprise an angle and/or a height of the first air deflection plate. For example, the first air deflector and/or the second air deflector may be air deflectors which can be turned between a turned-open position and a turned-closed position, and the air deflectors are opened to different angles, so that the area of a ventilation area of the air inlet can be adjusted. The third air deflector can be a lifting air deflector, and the distance between the air inlet and the air deflector can be adjusted by lifting the air deflector to different heights.

For example, the first opening position may refer to an angle of the first wind deflector. For example, the first air deflection can have three opening stations, namely three opening angles: the first angle, the second angle and the third angle respectively correspond to the following three temperature ranges: greater than or equal to 60 ℃ and less than 150 ℃, greater than or equal to 150 ℃ and less than 200 ℃, greater than or equal to 200 ℃.

In one example, the first air deflector may be controlled to open to a first angle if the temperature of the first burner is greater than or equal to 60 ℃ and less than 150 ℃, the first air deflector may be controlled to open to a second angle if the temperature of the first burner is greater than or equal to 150 ℃ and less than 200 ℃, and the first air deflector may be controlled to open to a third angle if the temperature of the first burner is greater than or equal to 200 ℃.

Through the scheme, the opening station of the first air deflector can be adjusted along with the lifting of the temperature of the first furnace end, so that the air inlet volume can be adjusted more flexibly.

According to an embodiment of the present invention, the second air guiding plate has a plurality of second opening stations corresponding to the plurality of temperature ranges one to one, and the cooker control device 130 is further configured to: when it is determined based on the temperature data that the temperature of the second furnace head 220 falls within a specific temperature range of the plurality of temperature ranges, a second station signal for controlling the second air deflector to open to a second open station corresponding to the specific temperature range is generated, the second station signal including the air deflector control signal.

The second opening station can include an angle and/or a height of the second air deflection. As described above, the second air deflection plate may be an air deflection plate that is reversible between a flipped open position and a flipped closed position.

For example, the second air deflection plate can have three opening stations, namely three opening angles: the first angle, the second angle and the third angle respectively correspond to the following three temperature ranges: greater than or equal to 60 ℃ and less than 150 ℃, greater than or equal to 150 ℃ and less than 200 ℃, greater than or equal to 200 ℃.

In one example, the second air deflector may be controlled to be opened to a first angle when the temperature of the second burner is greater than or equal to 60 ℃ and less than 150 ℃, the second air deflector may be controlled to be opened to a second angle if the temperature of the second burner is greater than or equal to 150 ℃ and less than 200 ℃, and the second air deflector may be controlled to be opened to a third angle if the temperature of the second burner is greater than or equal to 200 ℃.

Through the scheme, the opening station of the second air deflector can be adjusted along with the rise and fall of the temperature of the second furnace end, so that the air inlet volume can be adjusted more flexibly.

According to the embodiment of the present invention, the temperature detecting module 110 includes a first temperature probe and a second temperature probe, the first temperature probe is located around the first furnace head and is used for detecting the temperature of the first furnace head; the second temperature probe is positioned around the second furnace end and used for detecting the temperature of the second furnace end.

The first temperature probe may be located within a first predetermined distance around the first burner, which may be set as desired, e.g., 5 centimeters, 10 centimeters, etc. The second temperature probe may be located within a second predetermined distance around the second burner, which may be set as desired, e.g., 5 centimeters, 10 centimeters, etc. The two temperature probes are adopted to respectively detect the temperatures of the two furnace ends, and compared with a single temperature probe, the scheme can detect and obtain more accurate temperature data.

According to an embodiment of the present invention, the hob control device 130 is integrated on the pulse controller of the hob. The configuration mode that the cooker control device 130 is integrated on the pulse controller of the cooker can be adapted to the conventional cooker, which is beneficial to reducing the development cost.

According to an embodiment of the invention, the hob communication module 120 is a wireless communication module. The wireless communication is a transmission mode with low cost and stable performance, and data transmission between the cooker and the range hood in the wireless communication mode can provide better use experience for users.

According to another aspect of the invention, a range hood is also provided. Fig. 4 shows a schematic block diagram of a range hood 400 according to an embodiment of the present invention. It should be noted that the range hood 400 shown in fig. 4 is only an example and not a limitation of the present invention, and the present invention is not limited to the embodiment shown in fig. 4. For example, fig. 4 shows that range hood control device 420 is a control chip including a first chip 422 and a second chip 424 (to be described later), but range hood control device 420 may also be a single chip or include a greater number (e.g., three, etc.) of chips. Alternatively, range hood control device 420 may also be another type of device, such as a Programmable Logic Controller (PLC) or the like. For another example, the range hood 400 may not divide the switch control board 440 and the power supply board 450, but implement all components on the same circuit board. Also for example, both the light emitting diode display (fig. 4 referred to as an LED display for short) and the keys may be optional, i.e., range hood 400 may optionally include these components.

As shown in fig. 4, the range hood 400 includes a range hood communication module 410, a range hood control device 420, and an air deflection assembly 430.

The range hood communication module 410 is configured to receive temperature data sent by the cooker 100 or an air deflector control signal generated based on the temperature data, where the temperature data is obtained by detecting temperatures of a first burner and a second burner on the cooker 100.

The range hood communication module 410 may be a wired communication module or a wireless communication module that mates with the cooktop communication module 120.

The air guide plate assembly 430 includes a first air guide plate, a second air guide plate, a third air guide plate and a driving mechanism, the driving mechanism is used for driving the first air guide plate, the second air guide plate and the third air guide plate to independently open and close a first air inlet, a second air inlet and a 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. In fig. 2 and 4, the first air guiding plate is a left air guiding plate, the second air guiding plate is a right air guiding plate, and the third air guiding plate is a middle air guiding plate.

The range hood control device 420 is respectively connected with the range hood communication module 410 and the driving mechanism, and the range hood control device 420 is used for receiving temperature data or air deflector control signals from the range hood communication module 410 and controlling the driving mechanism to drive the air deflectors to be opened and closed based on the temperature data or the air deflector control signals.

The driving and controlling principle of the air deflection assembly 430 of the range hood has been described above, and will not be described herein again.

According to an embodiment of the present invention, the driving mechanism may include a lifting mechanism connected to a third air deflector, the third air deflector has a lifting closed position and a falling open position under driving of the lifting mechanism, the third air deflector closes the third air inlet when in the lifting closed position, and the third air deflector opens the third air inlet when in the falling open position.

The lifting mechanism can be arranged inside the shell of the range hood and connected with the third air deflector to drive the third air deflector to rise and fall (namely close and open). The rising and closing position of the third air deflector refers to the position of the third air deflector when the lifting mechanism is in the minimum telescopic state, at this time, the third air inlet is completely hidden relative to the outside of the range hood 400, and the third air inlet is closed. On the contrary, the falling open position of the third air deflector refers to the position of the third air deflector when the lifting mechanism is in the maximum telescopic state, at this time, the third air inlet is completely shown relative to the outside of the range hood 400, and the third air inlet is opened.

When a large amount of oil smoke appears in the kitchen, the lifting mechanism drives the third air deflector to move to the landing opening position, the third air inlet is opened, and at the moment, the oil smoke can enter the range hood 400 through the third air inlet and then is discharged to the outside of the kitchen. When the kitchen oil smoke is reduced to a certain degree, the lifting mechanism drives the third air deflector to move to the lifting closing position, the third air inlet is closed, and at the moment, the third air deflector isolates the peculiar smell and the residual oil smoke in the range hood 400 outside the kitchen environment.

The first turnover mechanism can be arranged inside a shell of the range hood 400 and connected with the first air deflector to drive the first air deflector to turn over between a turning-over opening position and a turning-over closing position. The second turnover mechanism may be disposed inside a housing of the range hood 400 and connected to the second air guide plate to drive the second air guide plate to turn over between the turning-over open position and the turning-over closed position.

The turning-off positions of the first air deflector and the second air deflector refer to positions of the air deflectors when the respective turning mechanisms are at the other end point of the turning stroke, at the moment, the corresponding air inlets are completely hidden relative to the outside of the range hood 400, and the corresponding air inlets are turned off.

When oil smoke appears on the first side (for example, the left side), the first air deflector is turned over and opened, the first air inlet is opened, and at the moment, the oil smoke can enter the range hood 400 through the first air inlet along the first air deflector and then is discharged out of the kitchen. When the first side oil smoke disappears, the first air deflector turns over and closes, so that the first air inlet is closed, and at the moment, the first air deflector isolates the peculiar smell and the residual oil smoke inside the range hood 400 and in the flue outside the kitchen environment. Similarly, when oil smoke appears on the second side (e.g., right side), the second air deflector is turned over and opened, the second air inlet is opened, and at this time, the oil smoke can enter the range hood 400 through the second air inlet along the second air deflector and then be discharged out of the kitchen. When the second side oil smoke disappears, the second air deflector turns over and closes, so that the second air inlet is closed, and the second air deflector isolates the peculiar smell and the residual oil smoke inside the range hood 400 and in the flue outside the kitchen environment.

Through the arrangement of the turnover, the occupied space when the first air deflector and the second air deflector are opened can be reduced, the using space of the range hood 400 can be further reduced, and the increase of the activity space of a user during cooking is facilitated.

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). Looking at table 1, it can be seen that when the temperature of the left burner or the right burner is greater than 60 ℃, the corresponding left air deflector or the right air deflector is opened (see the above embodiment related to the fifth temperature threshold). The middle air deflector is only opened if one of the left and right burners is at a temperature greater than 60 c and the other is at a temperature greater than 200 c (see the above embodiments relating to the second and third temperature thresholds). In the case where only one head is used (the temperature of the other head does not exceed 60 ℃), the operating range is selected on the basis of the range in which the temperature of this head is located, the low range not exceeding 200 ℃, and the high range exceeding 200 ℃ (see the above-mentioned embodiment relating to the sixth temperature threshold). Under the condition that the two furnace ends are used (the temperature exceeds 60 ℃), the fan only uses high grade when the temperature of the two furnace ends exceeds 200 ℃, and uses low grade under the other conditions.
