In order to at least partially solve the problems in the prior art, according to a first aspect of the present invention, there is provided a cooking appliance, which is provided with a left burner and a right burner, and is further provided with a fire detection device, a first control device and a first communication device, wherein the fire detection device is used for detecting the fire of the left burner and the right burner to generate a fire signal of the left burner and a fire signal of the right burner; the first control device is used for generating a driving and controlling signal according to the firepower signal of the left burner and the firepower signal of the right burner; the first communication device is used for transmitting the driving and controlling signals to the range hood so that the range hood can respectively and independently control the opening degree of the left air inlet door and the right air inlet door of the range hood based on the driving and controlling signals and control the working gear of the fan of the range hood.

The cooking stove with the arrangement can control the opening degree of the left and right air inlet doors of the range hood and the working gear of the fan through the firepower of the burner of the cooking stove. Therefore, the situation that the user forgets to turn on the smoke machine during cooking to diffuse indoor oil smoke and cause body damage can be avoided. Freeing the user's hands during cooking. Further, degree through the furnace end firepower carries out automatic and accurate control to the degree of opening of corresponding air inlet door, need not the user carry out loaded down with trivial details operation to the cigarette machine, has improved the degree of automation of cigarette machine, has improved user's use and has experienced. Finally, the stove detects the firepower of the stove head by using the firepower detection device, and then controls the range hood according to the firepower signal, so that the stove is easy to realize from the equipment realization perspective and has lower cost; and because the firepower detection precision is higher, the control precision is correspondingly higher.

Illustratively, the first control device generating the actuation signal includes performing the following operations: when the firepower signal of the left furnace end and the firepower signal of the right furnace end indicate that the firepower of the left furnace end is different from the firepower of the right furnace end, a first driving signal is generated, the first driving signal is used for controlling at least one air inlet door corresponding to the furnace end with larger firepower in the left air inlet door and the right air inlet door to be in a full-open state, and controlling the working gear of the fan to be a first working gear, wherein the driving signal comprises a first driving signal, and the first working gear is higher than the lowest working gear.

The stove with the arrangement can generate a first driving signal when the firepower of the stove head is different, and the driving signal is used for completely opening an air inlet door corresponding to a larger firepower stove head and controlling a fan to enter a first working gear higher than a lowest working gear. Therefore, the oil fume generated during cooking can be discharged in time; in addition, the completely opened air inlet door corresponds to the position of the burner with large fire power, and the burner with larger fire power generally generates more oil smoke, so that the smoke exhaust efficiency of the air inlet door can be ensured. Therefore, the integral smoke exhaust effect of the range hood is ensured.

Illustratively, the first driving signal is also used for controlling an air inlet door corresponding to a burner with smaller fire among the left air inlet door and the right air inlet door to enter a half-open state.

The stove with the arrangement can control the air inlet door corresponding to the burner with larger firepower to be completely opened and can also control the other air inlet door corresponding to the burner with smaller firepower to be in a half-open state. The total opening size of the air inlets of the cigarette machine can be improved by overlapping the ventilation areas of the two air inlets. The air inlet door in a half-open state shares part of oil smoke, and the smoke discharge pressure of the other air inlet door is reduced. Meanwhile, the cooker enables smoke exhaust of the range hood to be more targeted, and improves the smoke exhaust efficiency of the range hood.

Illustratively, the first control device generating the actuation signal includes performing the following operations: and when the firepower signal of the left furnace end and the firepower signal of the right furnace end indicate that the firepower of the left furnace end and the firepower of the right furnace end are minimum firepower, generating a second driving signal, wherein the second driving signal is used for controlling the left air inlet door and the right air inlet door to be in a full-open state and controlling the working gear of the fan to be the lowest working gear, and the driving signal comprises the second driving signal.

The cooking stove with the arrangement can completely open the left air inlet door and the right air inlet door corresponding to the left furnace end and the right furnace end when the firepower detection device detects that the left furnace end and the right furnace end are both in minimum firepower, so that oil smoke can be discharged as soon as possible. At the moment, the fire power states of the furnace ends are the minimum fire power, so that the generated oil smoke is not particularly large, the working gear of the fan is controlled to be the lowest working gear, the oil smoke can be discharged through the range hood as soon as possible, meanwhile, the working power of the fan is reduced as far as possible, and the consumed electric energy is reduced.

Illustratively, the first control device generating the actuation signal includes performing the following operations: and when the fire signal of the left furnace end and the fire signal of the right furnace end indicate that any one of the fire of the left furnace end and the fire of the right furnace end is the maximum fire, generating a third driving signal, wherein the third driving signal is used for controlling the left air inlet door and the right air inlet door to be in a full-open state and controlling the working gear of the fan to be the highest working gear, and the driving signal comprises the third driving signal.

Because when at least one of the left and right furnace ends is in the maximum fire power, the cooking can quickly generate oil smoke, and the generated oil smoke is relatively more. At this time, the first control device does not completely open the air inlet door corresponding to the burner with the big fire state independently, but completely opens all the air inlet doors, and controls the fan to enter the highest working gear. Therefore, the ventilation area of the air inlet of the range hood can be opened to the maximum. Therefore, the oil smoke generated during cooking can be exhausted in the shortest time, the smoke exhaust efficiency of the range hood is improved, and the smoke exhaust time is shortened.

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 cooktop, a range hood, a smoke range linkage system, a signal transmission method for a cooktop, and a control method for a smoke range. The stove is provided with a left stove head and a right stove head. The range hood is provided with a left air inlet door and a right air inlet door. The cooker can be used for automatically transmitting driving and controlling signals to the range hood so as to automatically drive and control the left air inlet door, the right air inlet door and the fan of the range hood according to the use conditions of the left burner and the right burner of the cooker. Therefore, the automatic linkage of the kitchen range and the range hood is realized, and the pumping and exhausting effect of the range hood is ensured.

According to one aspect of the present invention, a cooktop is provided. Fig. 1 shows a schematic block diagram of a hob according to an embodiment of the present invention. As shown in figure 1, the cooker is provided with a left burner and a right burner on the left side and the right side of the table surface of the cooker respectively. It is understood that the left burner and the right burner can be independently ignited, i.e., the ignition state and the fire power of the left burner and the right burner are independent of each other.

The hob is further provided with fire detection means 140, first control means 150 and first communication means 160. These devices may be powered by batteries, among other things.

The fire detection device 140 may be configured to detect the magnitudes of the fire of the left and right burner units, and generate the fire signal of the left burner unit and the fire signal of the right burner unit according to the magnitudes of the fire of the respective burner units.

Illustratively, the fire detection device 140 may be any suitable device as long as it can detect the fire of the left and right furnace heads. For example, the fire power detecting device 140 may be implemented by using a position sensor, and the position sensor may detect a rotation angle of an ignition knob for adjusting fire power of the cooker, so as to know the fire power. For another example, the thermal power detection device 140 may be implemented by a flow sensor. It is understood that the greater the gas consumption rate, the greater the fire power for the burner. The flow sensor can be arranged in a gas channel of the left furnace end and the right furnace end and used for detecting the gas flow flowing to the left furnace end or the right furnace end and further learning the firepower.

The first control means 150 may be electrically connected to the fire detection means 140 for generating the driving signal according to the fire signal of the left burner and the fire signal of the right burner from the fire detection means 140.

For example, the first control device 150 may be implemented by using electronic components such as a comparator, a register, and a digital logic circuit, or a processor chip such as a single chip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), and an Application Specific Integrated Circuit (ASIC), and a peripheral circuit thereof. The first control means 150 may be either inherited in the pulse controller of the hob or independent of the pulse controller. Upon receiving the fire power signal generated by the fire power detection means 140, the first control means 150 may generate a drive control signal based on the fire power signal.

The first communication means 160 may be connected to the first control means 150 for transmitting the control signals generated by the first control means 150 to the range hood. The first communication device 160 may be a wired communication module or a wireless communication module, which may be set as desired.

Figure 2 shows a schematic block diagram of a cigarette machine according to one embodiment of the invention. As shown in fig. 2, the range hood may include a left air inlet door 310, a right air inlet door 320, and a fan 330 disposed within the range hood exhaust channel. The left air inlet door 310 and the right air inlet door 320 of the range hood correspond to the left burner and the right burner of the range respectively. The driving and controlling signals can be used for respectively and independently controlling the opening degree of the left air inlet door 310 and the right air inlet door 320 of the range hood and controlling the working gear of the fan 330 of the range hood.

Illustratively, the left air inlet door 310 and the right air inlet door 320 of the range hood may be driven by respective drive mechanisms, which the range hood is capable of controlling, thereby enabling the opening and closing of the left air inlet and the right air inlet, respectively, independently of each other. Similar to the left burner and the right burner of the range, the left air inlet door 310 and the right air inlet door 320 of the range hood are also independently operated, and the opening degrees of the two are independent of each other. The air inlet is closed when the air inlet door is closed, and the air inlet is opened when the air inlet door is opened. Alternatively, the air inlet door may be an air deflector capable of adjusting the air inlet amount of the air inlet, for example, it may be an angle and/or height adjustable air deflector, the area of the ventable area of the air inlet corresponding to the air inlet door may be adjusted by changing the angle of the air inlet door, or the distance between the air inlet corresponding to the air inlet door and the air inlet door may be adjusted by changing the height of the air inlet door. That is to say, the air inlet door can switch between a plurality of different angles and/or a plurality of different heights when opening to realize different degrees of opening.

Illustratively, the fan 330 of the range hood has different operating positions, such as a stir-fry position, a high position, and a low position, which are sequentially reduced in intensity.

Different smoking effects of the range hood can be realized by controlling the left air inlet door 310, the right air inlet door 320 and the fan 330 of the range hood.

Therefore, the range with the arrangement can control the opening degree of the left and right air inlet doors of the range hood and the working gear of the fan through the firepower of the burner of the range. Therefore, the situation that the user forgets to turn on the smoke machine during cooking to diffuse indoor oil smoke and cause body damage can be avoided. Freeing the user's hands during cooking. Further, degree through the furnace end firepower carries out automatic and accurate control to the degree of opening of corresponding air inlet door, need not the user carry out loaded down with trivial details operation to the cigarette machine, has improved the degree of automation of cigarette machine, has improved user's use and has experienced. Finally, the stove detects the firepower of the stove head by using the firepower detection device, and then controls the range hood according to the firepower signal, so that the stove is easy to realize from the equipment realization perspective and has lower cost; and because the firepower detection precision is higher, the control precision is correspondingly higher.

Illustratively, the first communication device 160 may include an infrared communication device, a bluetooth communication device, a wireless hi-fi communication device, or the like. Correspondingly, a corresponding receiving device can also be arranged on the cigarette machine. The infrared communication device may transmit the driving and controlling signal generated by the first control device 150 through infrared rays. The bluetooth communication device may then transmit the actuation signal in the form of a digital signal. The wireless high-fidelity communication device has the advantages of low system complexity, low power spectral density of transmitted signals, insensitivity to channel fading, low interception capability, high positioning accuracy and the like, and is particularly suitable for high-speed wireless access in dense places such as indoor places.

Therefore, the first communication device 160 with the arrangement can realize accurate wireless transmission of signals between the cooker and the range hood, avoid the connection between the cooker and the range hood by using a data line, save space and avoid troubles caused by wiring.

Illustratively, for each of the left and right burner of the hob, the hob further comprises a corresponding regulating valve assembly 210, and the fire detection device 140 comprises a corresponding detection assembly 220. For example, the cooktop may include a left and right regulator valve assembly, and the fire detection device 140 may include a left and right detection assembly. Which are respectively corresponding to the left furnace end and the right furnace end one by one. Fig. 3 and 4 illustrate a perspective view and an exploded view, respectively, of a regulator valve assembly 210 provided with a sensing assembly 220, in accordance with one embodiment of the present invention. As shown in fig. 3 and 4, the modulator valve assembly 210 may include a valve body 211 and an operating member 212 provided on the valve body. The valve body 211 remains stationary during use of the cooktop. The operating member 212 is used to change a position in response to an operation by a user to adjust the fire power of the corresponding burner. In other words, the operating member 212 is movable. For example, the operation member 212 may be connected with an ignition knob of the cooker, and the operation member 212 may have different positions by the driving of the ignition knob, so that it may adjust an effective conduction area of the gas channel, thereby changing the throughput of the gas. The throughput of gas is positively correlated to the burner power, and the regulator valve assembly 210 can regulate the burner power. The detection component 220 of the fire detection apparatus 140 may be used to generate a fire signal representing different fire power according to the position of the operating member 212. The detection unit 220 can detect the position of the operation member 212, and since the position of the operation member 212 has a corresponding relationship with the heating power, the detection unit 220 can generate heating power signals indicating different heating powers according to different positions of the operation member 212. The detection assembly 220 may be implemented, for example, by providing a microswitch or encoder or the like associated with the operating member 212. Specifically, it will be described in detail below.

In the cooking utensils with this setting, through detecting the firepower of furnace end with the operating member of detecting element 220 and governing valve subassembly 210 of firepower detection device 140 associates, realized accurately detecting the firepower state of furnace end through simple structure, and then realized the accurate control to the cigarette machine.

Further, the detection assembly 220 may include a plurality of micro switches provided at different positions on the valve body 211 for assuming corresponding open and closed states according to the current position of the operation member 212 to generate fire signals representing different fire powers.

In the embodiment shown in fig. 3-4, detection assembly 220 includes an ignition microswitch 221 and a soft fire microswitch 222. The ignition microswitch 221 and the small fire microswitch 222 are in an off state when the cooktop is not in operation. The operating member 212 includes a pressure plate 214. When the user ignites, it presses the operating member 212. When the operating member 212 is pressed, the pressing plate 214 of the operating member 212 moves downward, and the ignition microswitch 221 is pressed down, so that the ignition microswitch 221 is closed. For example, the ignition microswitch 221 is closed, and a fire power signal indicating that the fire power of the corresponding burner is a big fire can be generated. When the first control device 150 detects that the ignition microswitch 221 is closed, it is considered that a fire signal indicating that the fire of the corresponding burner is a strong fire is received, and a strong fire control signal can be generated based on the received fire signal. As shown in fig. 3-4, the operating member further includes a stem 213, the stem 213 being rotatable relative to the valve body, a contact piece 215 may be provided on the stem 213, and the contact piece 215 may be an annular structure having a boss. The contact member 215 may rotate with the valve stem 213. A small fire microswitch 222 of the detection assembly 220 is provided on the moving path of the boss of the contact 215. When the boss rotates to an angle having the small fire microswitch 222 during the rotation of the contact 215 along with the valve rod 213, the small fire microswitch 222 is closed to generate a fire power signal indicating that the fire power of the corresponding burner is small fire. The first control device 150 can generate the small fire driving control signal according to the detected closing of the small fire microswitch 222.

It will be appreciated that although in the embodiment shown in fig. 3 and 4, the detection assembly 220 includes only 2 microswitches, this is merely an example. Alternatively, the detection assembly 220 may also include more than 3 microswitches. Each microswitch may be positioned at a different location on the path of travel of the boss of the contact member 215, as viewed axially of the valve stem 213. Different micro-switches may correspond to different fire conditions. After receiving the electric signal of closing the corresponding micro switch, the first control device 150 generates different driving and controlling signals to control the opening degree of the air inlet door of the range hood and the working gear of the fan according to the different driving and controlling signals.

It can be seen that the detection assembly 220 having the micro switch can easily realize that the first control device 150 receives different fire signals by detecting the position of the operation member 212. The micro switch has the advantages of simple structure and low cost, has small volume and can be arranged on the valve body 211 of the regulating valve component 210 without excessive occupied space. Meanwhile, since the transmission signal of the microswitch is simple, the processing logic of the first control device 150 for the heating power signal is simple, the calculation amount of the first control device 150 can be reduced, and the calculation speed of the first control device 150 can be increased.

Illustratively, the detection component 220 includes an encoder. As previously described, the operating member 212 of the regulator valve assembly 210 may include a valve stem 213. The encoder may be used to generate a fire signal indicating different levels of fire depending on the rotation angle of the valve stem 213. In one embodiment, an encoder may be disposed on the valve stem 213 of the regulator valve assembly 210, and the encoder rotates with the rotation of the valve stem 213. The detection assembly 220 may generate different fire signals according to the rotation angle of the damper assembly 210 by outputting the encoder to the first control device 150. Illustratively, the encoder may be a photoelectric encoder.

The detection component 220 with the encoder can continuously and steplessly detect the fire signal, i.e., the detected fire signal can be any value from the minimum fire state to the maximum fire state, rather than discrete. In this way, the operation of the executing parts of the range hood, such as the air inlet door and the blower, can be more precisely controlled according to the continuous driving and controlling signals output by the first control device 150, so as to improve the air draft performance of the range hood.

Exemplarily, the hob may also be provided with an ignition circuit 130 for independently igniting the left and right burner, respectively. Alternatively, the ignition circuit 130 may include two sub-circuits that are capable of independently igniting the left burner and the right burner, respectively. The ignition circuit 130 may be implemented using any ignition circuit known in the art or developed in the future, such as a piezo ceramic type ignition circuit or an electrical pulse type ignition circuit, and the operation principle and the use method thereof are well known to those skilled in the art. The first control device 150 can also be used for driving the ignition circuit 130 to ignite the corresponding burner according to the first fire signal. The first fire signal is one of the fire signals from the detection component 220 that represents different fires. In the embodiment shown in fig. 3 and 4, the signal detected by the first control means 150 that the ignition microswitch 221 is closed may be used as the first fire signal. Here, the first control means 150 not only generates a drive control signal for controlling the range hood using the first fire signal, but also drives the ignition circuit to ignite the corresponding burner using the first fire signal. That is, the ignition microswitch 221 of the same device can be used for driving the ignition circuit 130 and driving and controlling the smoke ventilator to control the air inlet door and the fan. Therefore, the utilization efficiency of the parts in the stove is improved, and the space and the cost for additionally utilizing other parts are saved.

Illustratively, the hob further comprises a fire detection circuit 170, the fire detection circuit 170 being configured to detect whether the left burner 110 and the right burner 120 are in a fired state, to generate a fired state signal indicating that the burners are in a fired state. The fire detection circuit 170 can actually detect whether a burner of the cooker is burning flame, but cannot detect fire. It is understood that the fire detection means 140, although capable of detecting the magnitude of fire, may have inaccurate detection results. For example, in the embodiment of fig. 3 and 4, although the ignition microswitch 221 is already closed, the flame may not actually be ignited on the burner for a variety of reasons, such as no gas in the line. The flame detection circuit 170 is used to detect whether a flame is actually present at the burner. For the case where flame is actually present on the burner, the flame detection circuit 170 generates a firing state signal indicating that the burner is in a firing state; otherwise, the firing circuit 170 does not generate the firing status signal.

The first control device 150 generating the actuation signal may include performing the following operations: and generating a driving and controlling signal when the first firing state signal is received within a preset time period after the fire signal of the left burner or the fire signal of the right burner is received. The firing state signal comprises a first firing state signal, and the first firing state signal indicates that the burner corresponding to the received firepower signal is in a firing state. The duration of the predetermined period of time may be preset, for example, to any value in the range of 7-12 seconds. The first control means 150 generates the driving signal if the fire signal of the left burner of the fire detection means 140 is received and the firing state signal indicating that the left burner is in the firing state is received within a predetermined time period after the fire signal is received. Similarly for the right burner, if a firing state signal indicating that the right burner is in a firing state is received again within a predetermined time period after the fire signal of the right burner is received, the first control means 150 also generates a drive control signal. In this embodiment, the presence of the firing state signal in addition to the fire power signal also serves as one condition for the first control device 150 to generate the drive control signal.

In one embodiment, the thermal detection circuit 170 may include a thermocouple. The thermocouple may be a combination of two different alloy materials. Different alloy materials can generate different thermoelectric potentials under the action of temperature, and the thermocouple can be manufactured by utilizing different thermoelectric potentials generated by different alloy materials under the action of temperature. The current firing state can be judged by detecting the thermoelectric force generated by the thermocouple.

Furthermore, the thermocouple can also be connected with a gas valve. Utilize thermoelectric force to keep the open mode of gas valve passageway, when furnace end flame was not lighted or when the use accident goes out, the thermoelectric force of thermocouple disappears, and gas valve passageway will be closed to avoid the gas to leak.

The cooking stove with the fire detection circuit 170 can avoid that the air inlet door of the range hood is still opened and the fan of the range hood is started under the condition that the flame of the furnace end is not ignited, so that the range hood does no work and wastes electricity.

For example, the first control means 150 generating the driving signal according to the fire signal of the left furnace head and the fire signal of the right furnace head may include performing the operations of: the first driving signal may be generated when the fire signal of the left furnace end and the fire signal of the right furnace end indicate that the fire of the left furnace end is different from the fire of the right furnace end. The fire power state can be detected by the fire power detection means 140. The first driving signal can be used for controlling at least one of the left air inlet door and the right air inlet door corresponding to the furnace end with larger firepower to be adjusted to a full-open state, and controlling the working gear of the fan to be a first working gear. The driving control signal comprises a first driving signal, and the first working gear is higher than the lowest working gear. The lowest working gear can be the working gear of the fan 330 corresponding to the range hood after the range hood receives the corresponding driving and controlling signals when the left burner and the right burner of the fan are both in small fire. Which will also be described in detail below.

In one example, the stove head of the stove has three fire states of small fire, big fire and extreme big fire. The blower 330 of the range hood has three working gears of a lowest working gear, a middle working gear and a highest working gear. The left air inlet door and the right air inlet door of the range hood have three opening degrees of closing, half opening and full opening (full opening).

Illustratively, the first control device 150 generates the first driving signal when the left burner is in a low fire state and the right burner is in a high fire state. The first drive signal will be used to control the right air inlet door 320 of the range hood to be fully opened, i.e., to cause the right air inlet of the range hood to be fully opened. Meanwhile, correspondingly, the range hood will also control the working gear of the fan 330 to be the middle working gear.

Conversely, when the left burner is in the big fire state and the right burner is in the small fire state, the first control device 150 will generate the corresponding first driving signal to control the left air inlet door 310 of the range hood to be fully opened and control the fan 330 to enter the middle working range.

That is, when the two burners have different powers, the first control device 150 will generate a first driving signal, which can be used to control the range hood to fully open the air inlet door corresponding to the burner in a relatively strong-fire state, and control the fan 330 to enter the first operating range with a higher smoking capacity than the lowest operating range.

Alternatively, assume that the burner of the hob has only two fire states, small and large. The fan 330 of the range hood has only two working positions, namely a lowest working position and a highest working position. The first drive signal may be used to control the operating range of the fan to be the highest operating range.

Therefore, the cooker with the arrangement can generate a first driving signal when the firepower of the burner is different, wherein the driving signal is used for completely opening the air inlet door corresponding to the burner with larger firepower and controlling the fan 330 to enter a first working gear higher than the lowest working gear. Therefore, the oil fume generated during cooking can be discharged in time; in addition, the completely opened air inlet door corresponds to the position of the burner with large fire power, and the burner with larger fire power generally generates more oil smoke, so that the smoke exhaust efficiency of the air inlet door can be ensured. Therefore, the integral smoke exhaust effect of the range hood is ensured.

Further, in the above example, the first driving signal may also be used to control the intake door corresponding to the less fire burner, of the left and right intake doors 310 and 320, to be brought into the half-open state. The half-open state of the air inlet door is between the full-open state and the closed state. As described above, when the firepower of the two burners is different and the firepower of one burner is relatively large, the corresponding air inlet door is fully opened, and the air inlet door corresponding to the other burner enters a half-open state. The air inlet door can be in a half-open state by controlling the opening angle or opening height of an air deflector arranged at the air inlet between closing and fully opening. Optionally, the opening size of the air inlet door in the half-open state can be regulated according to actual conditions. In this case, when the burner powers of the left and right inlet doors 310 and 320 are different, respectively, the inlet door corresponding to the burner having the smaller power may be brought into a half-open state of a fixed opening size, for example, a fixed opening angle. Alternatively, the air inlet door may have a half-open state of different opening degrees. For example, the air inlet door can have a plurality of different opening angles or opening heights when the air inlet door is in a half-open state. The first driving signal may be used to control the opening degree of an air inlet door corresponding to a lower-fire burner among the left and right air inlet doors 310 and 320 according to the fire of the lower-fire burner. When the firepower is small, the air inlet door can be in a first opening angle; when the firepower is increased by a little but still less than that of another burner, the air inlet door can be at a second opening angle, wherein the second opening angle is greater than the first opening angle. It can be understood that no matter the air inlet door is at the first opening angle or the second opening angle, the air inlet door is in a half-open state.

Therefore, the stove with the arrangement can control the air inlet door corresponding to the burner with larger firepower to be completely opened and can control the other air inlet door corresponding to the burner with smaller firepower to be in a half-open state. The total opening size of the air inlets of the cigarette machine can be improved by overlapping the ventilation areas of the two air inlets. The air inlet door in a half-open state shares part of oil smoke, and the smoke discharge pressure of the other air inlet door is reduced. Meanwhile, the cooker enables smoke exhaust of the range hood to be more targeted, and improves the smoke exhaust efficiency of the range hood.

Illustratively, the first control device 150 generating the actuation signal includes performing the following operations: when the fire signal of the left furnace end and the fire signal of the right furnace end indicate that the fire of the left furnace end and the fire of the right furnace end are both minimum fire, a second driving signal is generated. The fire power state can be detected by the fire power detection means 140. The second driving signal is used to control both the left air inlet door 310 and the right air inlet door 320 to enter a fully opened state, and control the operating range of the fan 330 to be a lowest operating range, wherein the driving signal includes the second driving signal.

Therefore, the kitchen range with the arrangement can completely open the left air inlet door 310 and the right air inlet door 320 corresponding to the left furnace end and the right furnace end when the fire detection device 140 detects that the left furnace end and the right furnace end are both in minimum fire, so that oil smoke can be discharged as soon as possible. At the moment, the fire power states of the furnace ends are the minimum fire power, so that the generated oil smoke is not particularly large, the working gear of the fan is controlled to be the lowest working gear, the oil smoke can be discharged through the range hood as soon as possible, meanwhile, the working power of the fan is reduced as far as possible, and the consumed electric energy is reduced.

Illustratively, the first control device 150 generating the actuation signal includes performing the following operations: when the fire signal of the left burner and the fire signal of the right burner indicate that either one of the fire of the left burner and the fire of the right burner is maximum fire, a third drive signal is generated. The third driving signal is used to control both the left air inlet door 310 and the right air inlet door 320 to enter a fully opened state, and control the operating range of the fan 330 to be the highest operating range, wherein the driving signal includes the third driving signal.

In the above example, when either the fire signal of the left burner or the fire signal of the right burner indicates extreme fire, a third drive signal is generated to control all the air inlet doors to enter the fully open state and control the fan to operate at the highest operating range.

Because when at least one of the left and right furnace ends is in the maximum fire power, the cooking can quickly generate oil smoke, and the generated oil smoke is relatively more. At this time, the first control device 150 does not completely open the air inlet doors corresponding to the burners having the big fire state alone, but completely opens all the air inlet doors, and controls the fan 330 to enter the highest operating range. Therefore, the ventilation area of the air inlet of the range hood can be opened to the maximum. Therefore, the oil smoke generated during cooking can be exhausted in the shortest time, the smoke exhaust efficiency of the range hood is improved, and the smoke exhaust time is shortened.

The following table 1 shows the correspondence between the fire signal of the burner of the cooking range and the working states of the air inlet door and the fan of the range hood in the above example.

TABLE 1 corresponding table for firepower and working state of range hood

The kitchen range in the example can give consideration to the power and the smoke exhaust efficiency of the smoke machine in the process of automatically controlling the smoke machine, can pertinently suck local oil smoke in the working area of the smoke machine, and improves the working effectiveness of the smoke machine.

In the above description, it is described in detail that when the fire power state of the cooker is changed, the first control device 150 generates a corresponding driving and controlling signal according to the change of the fire power state to control the range hood to change the operating state thereof. In other words, each time the fire status of the cooking appliance changes, the first control device 150 can immediately generate a corresponding driving and controlling signal and send the signal to the range hood by the first communication device 160 to control the range hood to change the working status correspondingly in real time.

For example, the first control device 150 may further include: when the fire state of the cooker is not changed all the time, for example, when the fire signal of the left burner, the fire signal of the right burner and the firing state signal are not changed all the time, the driving and controlling signal is generated at a fixed frequency. In other words, in the event that the cooktop is not operated by a user for an extended period of time, the cooktop may send a drive signal to the range hood once every predetermined time. The control signal can be the same as the firepower state of the cooker is not changed. For example, when both the left and right burner are in the minimum fire state, the first control device 150 generates the second driving signal. If no user operates the cooktop within 15 seconds, the first control device 150 will again generate the second drive signal to send to the range hood. And if the operation of the cooker is carried out within the preset time period, the timing is restarted to send the driving and controlling signal at the preset time period again. The above functions can be realized by a combination of a timer, a memory, and the like in the first control device 150, which are well known to those skilled in the art and will not be described in detail.

The second communication device 350 may be electrically connected with the second control device 340 to transmit the received actuation signal to the second control device 340. Illustratively, the range hood may be provided with a drive mechanism for the air inlet door. The second control device 340 may be connected to the driving mechanism of the air inlet door, and may control the driving mechanism of the corresponding air inlet door by a driving control signal, so as to adjust the opening degree of the air inlet door. That is, after receiving the driving and controlling signal transmitted by the cooker through the second communication device 350, the second control device 340 may determine and execute operations corresponding to the driving and controlling signal, such as adjusting the opening angle or height of the air inlet door, and changing the operating gear of the fan 330, that is, adjusting the actual output power of the fan.
