Hereinafter, a cooking appliance 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 should be noted that the cooking stove 100 shown in fig. 1 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. 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 cooker according to an embodiment of the present invention. Figure 3 shows a left side view of a range hood and a cooker according to an embodiment of the present 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 the 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 the air deflector in the air deflector assembly 430 of the range hood 400 based on the temperature data or the air deflector control signal, where the air deflector assembly 430 includes one or more air deflectors and a driving mechanism, and the driving mechanism is configured to drive the one or more air deflectors to independently open and close one or more air inlets of the range hood 400.

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

The air deflection assembly 430 may include a first air deflection plate, a second air deflection plate, a third air deflection plate, and a driving mechanism, where the driving mechanism is configured to drive the first air deflection plate, the second air deflection plate, and the third air deflection plate to independently open and close a first air inlet, a second air inlet, and a third air inlet of the range hood 100, 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 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.

The smoke ventilator control device 420 may be implemented by using electronic components such as a comparator, a register, and a digital logic circuit, or by using processor chips such as a single chip microcomputer, 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 peripheral circuits thereof.

For example, the driving mechanism of the range hood 400 may include one-to-one air deflector motor (not shown in fig. 4) corresponding to one or more air deflectors, and each air deflector motor may be configured to drive the corresponding air 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 motor driving current to the air deflector motor of each air deflector to drive each air deflector motor to rotate, so as to drive each air deflector to move.

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

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 460 connected to the main motor, and the motor driving circuit 460 is 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 the motor driving circuit 460 of the main motor, and the range hood control device 420 may also be configured to control the magnitude of the driving current output by the motor driving circuit 460, so as to control the rotation speed of the fan (i.e., the 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 each air deflector can be controlled based on the temperature data according to a preset rule, and then the opening and closing of each air deflector is controlled.

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.

Because the air deflector assembly 430 comprises 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 to smoke, so that the air inlet amount can be effectively increased, oil smoke can be quickly absorbed, 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.

According to the embodiment of the utility model provides a, having temperature detection module on the cooking utensils, can detecting the furnace end temperature of cooking utensils, can controlling opening and closing of each aviation baffle of lampblack absorber based on the temperature data that detect afterwards. 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 utility model, cooking utensils 100 still includes the cooking utensils controlling means 130 who is connected with temperature detection module 110 and cooking utensils communication module 120 respectively, and cooking utensils controlling means 130 is used for receiving the temperature data that temperature detection module 110 gathered to with temperature data or aviation baffle control signal transmission to cooking utensils communication module 120.

The cooker control device 130 may be built by using electronic components such as a comparator, a register, and a digital logic circuit, or may be implemented by using processor chips 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 peripheral circuits thereof.

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 the embodiment of the utility model provides a, cooking utensils controlling means 130 includes: the first stove comparator is connected with the temperature detection module 110 and is used for comparing the temperature of the first stove head 210 and the temperature of the second stove head 220 with a first temperature threshold value, and generating a first comparison signal if a first condition is met, otherwise generating a second comparison signal, wherein the first condition is that the temperature of any one of the first stove head 210 and the second stove head 220 is greater than the first temperature threshold value; the first cooker signal generator is connected with the first cooker comparator and the cooker communication module 120, and is configured to generate a first opening signal for controlling the third air deflector to open based on the first comparison signal output by the first cooker comparator, where the air deflector control signal includes the first opening signal.

Herein, any cooking appliance comparator (e.g., first cooking appliance comparator, second cooking appliance comparator, third cooking appliance comparator, etc.) and any range hood comparator (e.g., first range hood comparator, second range hood comparator, third range hood comparator, etc.) may be implemented using any suitable device or circuit capable of implementing a comparison function.

The first cooktop comparator can output any form of comparison result (i.e., comparison signal). In one example, the comparison signal output by the first cooktop comparator is a high level signal (i.e., the first comparison signal) to indicate that the first condition is satisfied or a low level signal (i.e., the second comparison signal) to indicate that the first condition is not satisfied.

The signal generator may generate various waveforms as desired. The signal output by the comparator is not generally suitable for the drive mechanism and can therefore be converted via a signal generator to generate a signal that can be suitable for the drive mechanism. For example, the first cooktop signal generator can generate a square wave signal based on the first comparison signal, so as to control the driving mechanism to drive the air deflector to move by using the square wave signal.

The first temperature threshold may be any suitable value, which may be set as desired, but is not limited by the present invention. 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.

The first cooktop timer can output any suitable form of signal. In one example, the signal output by the first hob timer is a low level signal or a pulse signal, and the moment of occurrence of the pulse indicates that the duration of the second comparison signal output after the first comparison signal at that moment just exceeds the first preset time.

For example, the second cooktop signal generator can generate a square wave signal based on the first timing signal, so as to control the driving mechanism to drive the air deflector to move by using the square wave signal. The signal that first cooking utensils time-recorder output is the low level, and second cooking utensils signal generator also can output the low level, and actuating mechanism does not drive the third aviation baffle motion this moment, and when the signal that first cooking utensils time-recorder output was pulse signal, second cooking utensils signal generator can output square wave signal, and the aviation baffle drives the third aviation baffle motion this moment so that the aviation baffle closes.

The first preset time may be any suitable time, which may be set as desired, 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.

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.

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 ℃.

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.

Table 1 shows the correspondence between the furnace end temperature, the fan operating position, and the air guide plate on-off state. In the embodiment shown in table 1, the operating range of the fan is divided into two ranges, namely a low range and a high range, and each of the three air deflectors has only two states of opening and closing. 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.
