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 range hood, an air intake control method for the 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, and the opening and closing of the three air deflectors are controlled based on the temperature of the stove burner acquired by the heat release module.

Hereinafter, a range hood according to an embodiment of the present invention will be described with reference to fig. 1 to 3. Fig. 1 shows a schematic block diagram of a range hood 100 according to one embodiment of the present invention. It should be noted that the range hood 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 that the control device 120 is a control chip including a first chip 122 and a second chip 124 (to be described later), but the control device 120 may be a single chip or include a larger number (e.g., three, etc.) of devices. Alternatively, the control device 120 may also be other types of devices, such as a Programmable Logic Controller (PLC) or the like. For another example, the range hood 100 may not divide the switch control board 140 and the power supply board 150, but implement all the components on the same circuit board. Also for example, both the light emitting diode display (fig. 1, abbreviated as LED display) and the keys may be optional, i.e., range hood 100 may optionally include these components.

As shown in fig. 1, the range hood 100 includes a heat releasing module 110, a control device 120, and an air deflection assembly 130.

The heat release module 110 is used to detect the temperature of a first burner and a second burner on the cooktop to obtain temperature data.

For example, the heat release module 110 may be disposed at any suitable position as long as it can detect the temperatures of the first burner and the second burner. It is noted that the temperature of any one burner means the temperature at a specific position within a predetermined distance (e.g., 10 cm) around the burner, which may be preset at the time of manufacturing or installing the range hood 100, and is known to the control device 120. The temperature at the particular location may be determined by the control device 120 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 heat release module and the burner of the cooktop can be understood with reference to fig. 2 and 3.

Illustratively, the pyroelectric module 110 may be implemented using a pyroelectric infrared sensor, such as an OTPA-16PM4S sensor. The pyroelectric module 110 may detect the temperature within a preset distance (i.e., its temperature detection range) in real time. For example, the pyroelectric module 110 can detect 256(16 × 16) temperature points at a time, i.e., the temperatures at 256 positions. The heat release module 110 may transmit the detected temperature data to the control device 120.

The air guiding plate assembly 130 includes a first air guiding plate, a second air guiding plate, a third air guiding plate, and a driving mechanism, wherein the driving mechanism is configured to drive the first air guiding plate, the second air guiding plate, and the third air guiding plate to open and close the first air inlet, the second air inlet, and the third air inlet independently from each other. In fig. 1 and 2, 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.

The control device 120 is connected to the heat releasing module 110 and the driving mechanism, and the control device 120 is configured to receive temperature data collected by the heat releasing module 110 and control the driving mechanism to drive the air deflectors to open and close based on the temperature data.

The control device 120 may be any suitable device having data processing capabilities and/or instruction execution capabilities. For example, the control device 120 may be implemented by 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.

The pyroelectric module 110 may be connected with the control device 120 by a wired or wireless manner. Accordingly, the heat releasing module 110 may transmit the collected temperature data to the control device 120 through a wired or wireless manner.

For example, the drive mechanism may include one-to-one air deflector motor (not shown in fig. 1) corresponding to three air deflectors, and each air deflector motor may be configured to drive a corresponding air deflector to move. Correspondingly, the driving mechanism may further include a motor driving circuit (not shown in fig. 1) 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 control device 120 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 100 may further include a blower including a general motor (shown as a dc motor in fig. 1) and a fan, the general motor being configured to drive the fan to rotate, thereby sucking the soot. In addition, the range hood 100 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. Alternatively, the control device 120 may be connected to a motor driving circuit of the overall motor, and the control device 120 may be further configured to control the magnitude of the driving current output by the motor driving circuit, so as to control the rotation speed of the fan (i.e., the operating range of the fan). An embodiment in which the control device 120 controls the operating range of the fan will be described below.

After receiving the temperature data transmitted by the heat releasing module 110, the control device 120 may control the driving current corresponding to one or more of the first air deflector, the second air deflector, and the third air deflector according to a preset rule based on the temperature data, so as to control the opening and closing of each air deflector.

According to the range hood disclosed by the embodiment of the invention, as the air deflector assembly 130 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, the scheme is an automatic and intelligent air deflector control scheme, the on-off control of the air deflector can be realized without user operation, and the scheme can effectively improve the user experience.

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 100, 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 100, 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 100 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 100 outside the kitchen environment.

According to the invention, the third air inlet is arranged between the first air inlet and the second air inlet, so that the area of the air inlet can be increased, and when the oil smoke generated by cooking is large, the third air inlet can be opened, so that the oil smoke can be rapidly and completely absorbed, and the environmental sanitation of a kitchen and the health of a user can be effectively protected. The third air inlet is opened and closed by the third air deflector in a rising and falling mode, the third air inlet can be opened only when a large amount of oil smoke appears, the third air inlet is kept closed at other times, and therefore the purposes of isolating the inside and the outside of the range hood and protecting devices inside the range hood can be achieved.

According to the embodiment of the invention, the driving mechanism may include a first turning mechanism connected to the first air deflector and a second turning mechanism connected to the second air deflector, the first air deflector has a turning open position and a turning closed position under the driving of the first turning mechanism, the first air inlet is opened when the first air deflector is in the turning open position, the first air inlet is closed when the first air deflector is in the turning closed position, the second air deflector has a turning open position and a turning closed position under the driving of the second turning mechanism, the second air inlet is opened when the second air deflector is in the turning open position, and the second air inlet is closed when the second air deflector is in the turning closed position.

The first turnover mechanism may be disposed inside a housing of the range hood 100 and connected to the first air guide plate to drive the first air guide plate to turn over between the turning-over open position and the turning-over closed position. The second turnover mechanism may be disposed inside a housing of the range hood 100 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 open 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 one end point of a turning stroke, at the moment, corresponding air inlets are all shown relative to the outside of the range hood 100, and the corresponding air inlets are opened. 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 this time, the corresponding air inlets are completely hidden relative to the outside of the range hood 100, 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 100 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 residual oil smoke in the interior of the range hood 100 and the flue outside the kitchen environment. Similarly, when oil smoke appears on the second side (for example, the 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 100 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 residual oil smoke inside the range hood 100 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 100 can be further reduced, and the increase of the activity space of a user during cooking is facilitated.

Illustratively, each of the first and second flipping mechanisms includes: a motor fixed in the housing of the range hood 100; the first transmission rod is provided with a first end and a second end, and the first end is connected to a rotating shaft of the motor; and a second drive link having a third end pivotably connected to the second end and a fourth end pivotably connected to the respective first or second air deflection plate.

For example, the first flipping mechanism may include a motor, a first driving lever, and a second driving lever. Wherein the motor is fixed inside the housing of the range hood 100. The first end of the first transmission rod is provided with a structure matched with the rotating shaft of the motor, such as a hole, and the first end of the first transmission rod is connected with the rotating shaft of the motor through the hole. The second end and the third end of the second drive link are provided with mating structures, such as shaft holes, to pivotally couple the first and second drive links together. The fourth end of the second transmission rod and the first air deflector are provided with matched structures, such as shaft holes, so that the second transmission rod and the first air deflector can be connected together in a pivoting mode. Through the arrangement, the side wall of the oil fume shell, the first transmission rod, the second transmission rod and the first air deflector form a four-bar linkage mechanism, so that the function of finally driving the first air deflector to turn over through the first transmission rod and the second transmission rod by the rotation of the rotating shaft of the motor is realized. The structure and the working principle of the second turnover mechanism are similar, and the detailed description is omitted.

The turnover mechanism realized by the motor, the first transmission rod and the second transmission rod has simple element structure, low processing cost, light weight and small volume, can effectively reduce the weight and the manufacturing cost of the range hood 100, and simplifies the internal structure thereof.

Illustratively, the lifting mechanism may include: a linear motor fixed in the housing of the range hood 100; the sliding rail is provided with a fixed part and a sliding part, the fixed part is fixed in the shell of the range hood 100, the sliding part is connected to the linear motor and the third air deflector, and the linear motor drives the third air deflector to rise and fall through the sliding part.

The elevating mechanism of the range hood 100 is provided with a linear motor and a slide rail. The linear motor is fixed inside the housing of the range hood 100 by a screw connection. The slide may be similar to the slide used with drawers. The slide rail includes a fixed portion and a sliding portion. The fixed portion is fixed in the housing of the range hood 100, for example, by a screw connection. The sliding portion may be connected to the linear motor and the third air guide plate. For example, one end of the sliding portion may be provided with a structure matching the rotation shaft of the linear motor, such as a hole, through which the transmission shaft of the linear motor is coupled. The other end of the sliding part can be fixed on the third air deflector through three support rods and can be connected with the fixed part in a sliding way through a sliding chute or other forms. When the transmission shaft of the linear motor stretches out, the sliding part is driven to synchronously move downwards along the track of the fixed part, and the third air deflector is driven by the three support rods to realize the landing function, so that the third air inlet is opened. Similarly, when the transmission shaft of the linear motor retracts, the sliding part is driven to synchronously move upwards along the track of the fixed part, and the third air deflector is driven by the three support rods to realize the lifting function, so that the third air inlet is closed. Through the arrangement, the noise generated by the third air deflector in the lifting and falling processes can be effectively reduced, and the movement resistance is reduced, so that the power of the linear motor is reduced, and the purposes of energy conservation and emission reduction are achieved.

According to an embodiment of the present invention, the control device 120 may be specifically configured to: and when it is determined based on the temperature data that a first condition is met, controlling the driving mechanism to drive 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.

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 present invention, the control device 120 may specifically be configured to: and under the condition that the third air deflector is opened, controlling the driving mechanism to drive the third air deflector to be closed when the state that the first condition is not satisfied is determined to continue for the first preset time based on the temperature data.

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 present invention, the control device 120 may specifically be configured to: controlling the drive mechanism to drive the third air deflection plate to open when it is determined based on the temperature data that a second condition is satisfied, wherein the second condition is that the temperature of either 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.

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 present invention, the control device 120 may specifically be configured to: and under the condition that the third air deflector is opened, controlling the driving mechanism to drive the third air deflector to be closed when the state that the second condition is not satisfied is determined to continue for the second preset time based on the temperature data.

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 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 present invention, the control device 120 may specifically be configured to: and controlling the driving mechanism to drive the third air deflector to be opened when a third condition is determined to be met based on the temperature data, wherein the third condition is that the sum of the temperatures of the first furnace head 210 and the second furnace head 220 is greater than a fourth temperature threshold value.

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 present invention, the control device 120 may specifically be configured to: and under the condition that the third air deflector is opened, controlling the driving mechanism to drive the third air deflector to be closed when the state that the third condition is not satisfied is determined to continue for a third preset time based on the temperature data.

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 situation that the third condition is not satisfied is determined to last for the third preset time, the driving mechanism is controlled to drive the third air deflector to close, the scheme can intelligently and automatically close the air deflector in time, and user experience is good.

According to an embodiment of the present invention, the control device 120 may specifically be configured to: when it is determined that a fourth condition is met based on the temperature data, controlling the driving mechanism to drive the first air deflector to open, wherein the fourth condition is that the temperature of the first furnace head 210 is greater than a fifth temperature threshold; and/or controlling the driving mechanism to drive the second air deflector to be opened when a fifth condition is determined to be met based on the temperature data, wherein the fifth condition is that the temperature of the second furnace end 220 is greater than a fifth temperature threshold value.

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 present invention, the control device 120 may specifically be configured to: under the condition that the first air deflector is opened, when the fourth condition is determined to be unsatisfied for a fourth preset time based on the temperature data, controlling the driving mechanism to drive the first air deflector to be closed; and/or, when the fifth condition is determined to be unsatisfied for the fifth preset time based on the temperature data under the condition that the second air deflector is opened, controlling the driving mechanism to drive the second air deflector to be closed.

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 the embodiment of the present invention, the range hood 100 may further include a fan, and the control device 120 may further be configured to: and controlling the working gear of the fan based on the temperature data.

As mentioned above, the control device 120 can also be used to control the operating range of the fan by controlling the drive current of the total motor. 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.

For example, as the temperature of either or both of the burners increases, the control device 120 may increase the operating range of the fan accordingly. The scheme can further provide larger air intake 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 operating positions corresponding to a plurality of temperature ranges, and the control device 120 may specifically be configured to: when it is determined that the temperature of any one of the first furnace end and the second furnace end is less than a sixth temperature threshold value and the temperature of the other one of the first furnace end and the second furnace end falls within a specific temperature range of the plurality of temperature ranges based on the temperature data, controlling the fan to work at a working gear corresponding to the specific temperature range; when it is determined based on the temperature data that the temperature of any one of the first and second furnace ends 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 ends falls within a second temperature range of the plurality of temperature ranges, controlling the fan to operate at an operating range corresponding to the first temperature range, or the second temperature range, or any temperature range between the first and second temperature ranges.

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 control device 120 may specifically be configured to: when the temperature of the first furnace end is determined to fall into a specific temperature range in the plurality of temperature ranges based on the temperature data, the driving mechanism is controlled to drive the first air deflector to be opened to a first opening station corresponding to the specific temperature range.

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 driving mechanism may be controlled to drive the first air deflector 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 driving mechanism may be controlled to drive the first air deflector 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 driving mechanism may be controlled to drive the first air deflector 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 a plurality of temperature ranges one to one, and the control device 120 may specifically be configured to: and when the temperature of the second furnace end is determined to fall into a specific temperature range in the plurality of temperature ranges based on the temperature data, controlling the driving mechanism to drive the second air deflector to be opened to a second opening station corresponding to the specific temperature range.

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 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, when the temperature of the second furnace end is greater than or equal to 60 ℃ and less than 150 ℃, the driving mechanism may be controlled to drive the second air deflector to open to a first angle, if the temperature of the second furnace end is greater than or equal to 150 ℃ and less than 200 ℃, the driving mechanism may be controlled to drive the second air deflector to open to a second angle, and if the temperature of the second furnace end is greater than or equal to 200 ℃, the driving mechanism may be controlled to drive the second air deflector to open to a third angle.

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 invention, the heat releasing module 110 is positioned in the middle of the top of the range hood 100, so that the temperatures of the two burner heads can be detected relatively uniformly, and the temperature detection error is reduced. Referring to fig. 2, the position of the heat release module is shown. Alternatively, the heat releasing module 110 may be disposed at any position as long as its temperature detection range can cover the first and second burners.

Alternatively, the pyroelectric module 110 may include one or more pyroelectric infrared sensors. Because the temperature detection range of the pyroelectric infrared sensor is wider, the temperature of the two furnace ends can be detected by adopting a single pyroelectric infrared sensor generally, and the cost can be effectively saved by adopting the scheme. Of course, a plurality of pyroelectric infrared sensors may be provided as necessary. For example, two pyroelectric infrared sensors may be respectively installed above the first burner and the second burner, wherein the first pyroelectric infrared sensor is used for detecting the temperature of the first burner, and the second pyroelectric infrared sensor is used for detecting the temperature of the second burner.

According to the embodiment of the present invention, the range hood 100 may further include an input component, configured to receive air deflector indication information, which is input by a user and used to indicate opening and closing of the air deflectors in the air deflector component 130, the control device 120 is connected to the input component, and the control device 120 may further be configured to control the driving mechanism to drive each air deflector to open and close based on the air deflector indication information.

Illustratively, the input component may be any hardware capable of receiving user instructions, which may include one or more of a keyboard, a mouse, a microphone, a touch screen, and the like, for example. The input component can also be a wired or wireless communication component for receiving the air deflector indication information input by the user and transmitted by the external equipment. The external device may be a personal computer, a mobile terminal, a server, etc.

For example, a switch control panel of the range hood may be provided with a plurality of air deflector control buttons, for example, three air deflector control buttons, which are respectively used for controlling the opening and closing of the three air deflectors. For example, when a user presses a first air deflector control key, the corresponding control driving mechanism can drive the first air deflector to be opened, and when the user presses the first air deflector control key again, the driving mechanism can be controlled to drive the first air deflector to be closed.

The air guide plate opening and closing control device has the advantages that an input assembly is provided for a user, the user can conveniently control the opening and closing of each air guide plate in a manual mode when needed, the user can have a large degree of freedom of control, and user experience is good.

For example, the input component may be further configured to receive mode indication information for indicating an automatic control mode, which is input by a user, and the control device 120 may be further configured to receive temperature data collected by the heat release module 110 in response to receiving the mode indication information, and control the driving mechanism to drive the air deflectors to open and close based on the temperature data.

Illustratively, the input assembly may further include a manual/automatic control button for switching the control mode between a manual control mode and an automatic control mode. For example, when the user presses the manual/automatic control button for the first time, the manual control mode is turned on, the user may control the switches of the air deflectors through the air deflector control button, and when the user presses the manual/automatic control button again, the automatic mode is turned on, and the control device 120 may start to read the temperature data and control the switches of the air deflectors based on the temperature data.

According to the embodiment of the present invention, the range hood 100 may further include a switch control board 140 and a power board 150, the control device 120 includes a first chip 122 and a second chip 124, the first chip 122 is integrated on the switch control board 140, the second chip 124 is integrated on the power board 150, the first chip 122 is connected to the pyroelectric module 110, and is configured to receive temperature data and transmit the temperature data to the second chip 124; the second chip 124 is connected to the driving mechanism, and is configured to receive the temperature data and control the driving mechanism to drive the air deflectors to open and close based on the temperature data.

Referring back to fig. 1, the switch control board 140 and the power board 150 are shown. The switch control panel 140 may be disposed on the front side of the range hood 100, and is mainly used for interacting with a user, for example, the user may input an instruction through a key (e.g., the above-mentioned air deflector control key, the manual/automatic control key, etc.) on the switch control panel 140, and may view information (e.g., a working gear of a fan, etc.) related to the range hood through an LED display device on the switch control panel 140.

The power board 150 may be disposed inside a housing of the range hood 100, and is mainly used to supply power to various components of the range hood. The power board 150 may include a power circuit and a motor driving circuit of the overall motor, etc. The first chip 122 and the second chip 124 are integrated on the switch control board 140 and the power board 150, respectively, and may communicate by wire or wirelessly.

Preferably, the heat releasing module 110 is also disposed at the front of the range hood 100 to facilitate the detection of the first and second burner. Therefore, the pyroelectric module 110 can be connected with the first chip 122, and the temperature data is transmitted to the second chip 124 through the first chip 122, so that the second chip 124 controls the opening and closing of the air deflector.

The control device is separated, the range hood 100 can conveniently perform distributed layout on all parts, the influence among circuits is reduced, and the separation scheme can be well adapted to the conventional range hood framework, so that the development cost can be reduced.

An exemplary intake air control manner of the range hood 100 is described below in conjunction with table 1. 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.

According to another aspect of the invention, an air inlet control method for a range hood is provided. Fig. 4 shows a schematic flow chart of an air intake control method 400 for a range hood according to one embodiment of the invention. The air intake control method 400 for the range hood includes steps S410 and S420.

In step S410, the temperatures of the first and second burners 210 and 220 on the cooktop are detected to obtain temperature data.
