Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a range hood, an air intake control method for the range hood, and a storage medium. Background Art

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

[0003] The air deflector of a range hood is a crucial component, controlling the opening and closing of the rear air inlet. Its primary function is to guide the collected fumes, allowing them to be discharged outdoors through the air inlet. Existing range hoods typically have only one air deflector, meaning only one air inlet, which can be opened or closed.

[0004] Because there is only one air inlet, the existing range hoods have limited flexibility in their extraction modes and ineffective extraction, making it difficult to quickly remove fumes, which pollutes the kitchen environment. Furthermore, in the existing technology, users are often required to manually open and close the air deflector, which is inconvenient and lacks a good user experience. Summary of the Invention

[0037] In the following description, a large amount of detail is provided to facilitate a thorough understanding of the present invention. However, it will be appreciated by those skilled in the art that the following description merely illustrates preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well known in the art have not been described in detail.

[0038] To at least partially address the aforementioned technical issues, embodiments of the present invention provide a range hood, an air intake control method for a range hood, and a storage medium. The range hood according to embodiments of the present invention has three air deflectors that open and close different air inlets. The opening and closing of the three air deflectors are controlled based on the stove burner temperature collected by a pyroelectric module. This range hood allows for flexible and convenient adjustment of the air intake volume, facilitating more timely and effective extraction of oil fumes.

[0039] Next, we will combine Figures 1 to 3 A range hood according to an embodiment of the present invention is described. Figure 1 FIG. 1 shows a schematic block diagram of a range hood 100 according to an embodiment of the present invention. Figure 1 The range hood 100 shown is only an example and is not intended to limit the present invention. The present invention is not limited to Figure 1 For example, Figure 1 The control device 120 is shown as a control chip, which includes a first chip 122 and a second chip 124 (to be described below), but the control device 120 can also be a single chip or include a larger number of chips (for example, three chips). Alternatively, the control device 120 can also be another type of device, such as a programmable logic controller (PLC). For another example, the range hood 100 can implement all components on the same circuit board without separating the switch control board 140 and the power board 150. For another example, the light emitting diode display device ( Figure 1 The LED display (abbreviated as LED display) and buttons can be optional, that is, the range hood 100 can optionally include these components.

[0040] like Figure 1 As shown, the range hood 100 includes a pyrolysis module 110 , a control device 120 and an air guide plate assembly 130 .

[0041] The pyroelectric module 110 is used to detect the temperatures of the first burner and the second burner on the stove to obtain temperature data.

[0042] For example, the pyroelectric module 110 can be located in any suitable location, as long as it can detect the temperature of the first and second burners. It should be noted that the temperature of any burner refers to the temperature at a specific location within a predetermined distance (e.g., 10 cm) around the burner. This specific location may be pre-set during the production or installation of the range hood 100 and is known to the control device 120. The temperature at this specific location can be determined by the control device 120 based on the temperature data. It will be understood that if there is a pot above the burner, the temperature of any burner refers to the temperature inside the pot above it.

[0043] Figure 2 A front view of a range hood and a stove according to one embodiment of the present invention is shown. Figure 3 FIG2 shows a left side view of a range hood and a stove according to an embodiment of the present invention. Figure 2 and Figure 3 Understand the positional relationship between the pyroelectric module and the burner of the stove.

[0044] For example, the pyroelectric module 110 can be implemented using a pyroelectric infrared sensor, such as an OTPA-16PM4S sensor. The pyroelectric module 110 can 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 locations. The pyroelectric module 110 can transmit the detected temperature data to the control device 120.

[0045] The air deflector assembly 130 includes a first air deflector, a second air deflector, a third air deflector, and a driving mechanism, which is used to drive the first air deflector, the second air deflector, and the third air deflector to independently open and close the first air inlet, the second air inlet, and the third air inlet. Figure 1 and 2 , it is shown that the first air guide plate is the left air guide plate, the second air guide plate is the right air guide plate, and the third air guide plate is the middle air guide plate.

[0046] When the deflector is closed, the air inlet is closed; when it is open, the air inlet is open. Alternatively, the deflector can be a plate capable of adjusting the amount of air entering the air inlet. For example, it can be an angle- and / or height-adjustable plate. By changing the angle of the deflector, the ventilated area of ​​the corresponding air inlet can be adjusted, or by changing the height of the deflector, the distance between the corresponding air inlet and the deflector can be adjusted. In other words, when the deflector is open, it can be switched between multiple angles and / or heights. Alternatively, the deflector can be a plate that only has two states: open and closed.

[0047] The control device 120 is connected to the pyroelectric module 110 and the driving mechanism respectively. The control device 120 is used to receive temperature data collected by the pyroelectric module 110 and control the driving mechanism to drive each air guide plate to open and close based on the temperature data.

[0048] 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 using one or a combination of a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic array (PLA), a microprocessor, a central processing unit (CPU), an application specific integrated circuit (ASIC), and other processing units.

[0049] The pyroelectric module 110 can be connected to the control device 120 via a wired or wireless manner. Accordingly, the pyroelectric module 110 can transmit the collected temperature data to the control device 120 via a wired or wireless manner.

[0050] Exemplarily, the driving mechanism may include an air deflector motor ( Figure 1 (not shown), each air deflector motor can be used to drive the corresponding air deflector to move. Accordingly, the driving mechanism can also include a motor driving circuit ( Figure 1 (not shown), the circuit can be used to output driving current to the first air guide plate motor of the first air guide plate, the second air guide plate motor of the second air guide plate and the third air guide plate motor of the third air guide plate to drive each air guide plate motor to rotate, thereby driving each air guide plate to move.

[0051] Exemplarily, the control device 120 can control the magnitude of the driving current output to each of the first air guide plate motor of the first air guide plate, the second air guide plate motor of the second air guide plate, and the third air guide plate motor of the third air guide plate to control the rotation of each air guide plate motor, and thereby control the opening and closing of each air guide plate.

[0052] Exemplarily, the range hood 100 may further include a fan, the fan including a main motor ( Figure 1 The range hood 100 includes a main motor (shown as a DC motor) and a fan, the main motor is used to drive the fan to rotate, thereby sucking out oil smoke. In addition, the range hood 100 may further include a motor drive circuit connected to the main motor, the motor drive circuit is used to output a drive current to the main motor to control the rotation of the main motor. Optionally, the control device 120 can be connected to the motor drive circuit of the main motor, and the control device 120 can also be used to control the size of the drive current output by the motor drive circuit, thereby controlling the speed of the fan (i.e., the working gear of the fan). An embodiment of the control device 120 controlling the working gear of the fan will be described below.

[0053] After receiving the temperature data transmitted by the thermal release module 110, the control device 120 can control the driving current corresponding to one or more of the first air guide plate, the second air guide plate and the third air guide plate based on the temperature data according to preset rules, thereby controlling the opening and closing of each air guide plate.

[0054] According to the range hood of an embodiment of the present invention, since the air deflector assembly 130 includes three air deflectors, when the first air deflector and / or the second air deflector cannot effectively draw in smoke, the third air deflector can be opened, that is, the third air inlet is opened to assist the first air inlet and / or the second air inlet in drawing in smoke. This can effectively increase the air intake volume, thereby quickly drawing in oil smoke and reducing kitchen environmental pollution. This control scheme can quickly and flexibly adjust the air intake volume, effectively helping to draw in oil smoke. In addition, this scheme is an automated and intelligent air deflector control scheme that can realize the opening and closing control of the air deflector without user operation. This scheme can effectively improve the user experience.

[0055] According to an embodiment of the present invention, the driving mechanism may include a lifting mechanism connected to the third air guide plate, and the third air guide plate has a raised closed position and a lowered open position under the drive of the lifting mechanism. When the third air guide plate is in the raised closed position, the third air inlet is closed, and when the third air guide plate is in the lowered open position, the third air inlet is opened.

[0056] The lifting mechanism can be disposed within the range hood housing and connected to the third air deflector to drive the third air deflector to rise and fall (i.e., close and open). The raised, closed position of the third air deflector refers to the position of the third air deflector when the lifting mechanism is at its minimum extension and contraction. At this point, the third air inlet is completely hidden from the exterior of the range hood 100, and the third air inlet is closed. Conversely, the lowered, open position of the third air deflector refers to the position of the third air deflector when the lifting mechanism is at its maximum extension and contraction. At this point, the third air inlet is fully visible from the exterior of the range hood 100, and the third air inlet is open.

[0057] When a large amount of cooking fumes are emitted from the kitchen, the lifting mechanism drives the third air deflector to its lowered, open position, opening the third air inlet. The cooking fumes can then enter the range hood 100 through the third air inlet and be discharged outside the kitchen. When the cooking fumes decrease to a certain level, the lifting mechanism drives the third air deflector to its raised, closed position, closing the third air inlet. The third air deflector now isolates odors and residual cooking fumes from the range hood 100 outside the kitchen environment.

[0058] The present invention increases the area of ​​the air inlet by providing a third air inlet between the first and second air inlets. When cooking generates significant amounts of fumes, the third air inlet can be opened to quickly remove the fumes, effectively protecting the kitchen environment and user health. The third air deflector raises and lowers to open and close the third air inlet. This allows the third air inlet to be opened only when significant amounts of fumes are present and remains closed at all other times. This effectively isolates the interior of the range hood from the outside while protecting the internal components of the range hood.

[0059] According to an embodiment of the present invention, the driving mechanism may include a first flipping mechanism connected to the first air guide plate and a second flipping mechanism connected to the second air guide plate. The first air guide plate has a flip-open position and a flip-closed position under the drive of the first flipping mechanism. When the first air guide plate is in the flip-open position, the first air inlet is opened, and when the first air guide plate is in the flip-closed position, the first air inlet is closed. The second air guide plate has a flip-open position and a flip-closed position under the drive of the second flipping mechanism. When the second air guide plate is in the flip-open position, the second air inlet is opened, and when the second air guide plate is in the flip-closed position, the second air inlet is closed.

[0060] The first flipping mechanism can be arranged inside the housing of the range hood 100 and connected to the first air guide plate to drive the first air guide plate to flip between a flip-open position and a flip-closed position. The second flipping mechanism can be arranged inside the housing of the range hood 100 and connected to the second air guide plate to drive the second air guide plate to flip between a flip-open position and a flip-closed position. The flip-open position of the first air guide plate and the second air guide plate refers to the position of each air guide plate when the respective flipping mechanism is at one end point of the flipping stroke, at which time the corresponding air inlet is fully exposed relative to the outside of the range hood 100, and the corresponding air inlet is open. The flip-closed position of the first air guide plate and the second air guide plate refers to the position of each air guide plate when the respective flipping mechanism is at the other end point of the flipping stroke, at which time the corresponding air inlet is fully hidden relative to the outside of the range hood 100, and the corresponding air inlet is closed.

[0061] When oil smoke appears on the first side (for example, the left side), the first air guide plate flips open and the first air inlet opens. At this time, the oil smoke can follow the first air guide plate and enter the interior of the range hood 100 through the first air inlet, and then be discharged outside the kitchen. When the oil smoke on the first side disappears, the first air guide plate flips closed, so the first air inlet is closed. At this time, the first air guide plate isolates the odor and residual oil smoke inside the range hood 100 and in the flue from the kitchen environment. Similarly, when oil smoke appears on the second side (for example, the right side), the second air guide plate flips open and the second air inlet opens. At this time, the oil smoke can follow the second air guide plate and enter the interior of the range hood 100 through the second air inlet, and then be discharged outside the kitchen. When the oil smoke on the second side disappears, the second air guide plate flips closed, so the second air inlet is closed. At this time, the second air guide plate isolates the odor and residual oil smoke inside the range hood 100 and in the flue from the kitchen environment.

[0062] This flipping arrangement can reduce the space occupied by the first air guide plate and the second air guide plate when they are opened, thereby reducing the usable space of the range hood 100 and helping to increase the user's activity space when cooking.

[0063] Exemplarily, each of the first flipping mechanism and the second flipping mechanism includes: a motor, which is fixed in the housing of the range hood 100; a first transmission rod, which has a first end and a second end, and the first end is connected to the rotating shaft of the motor; and a second transmission rod, which has a third end and a fourth end, the third end is pivotally connected to the second end, and the fourth end is pivotally connected to the corresponding first air guide plate or the second air guide plate.

[0064] For example, the first flipping mechanism may include a motor, a first transmission rod and a second transmission rod. The motor is fixed inside the housing of the range hood 100. The first end of the first transmission rod is provided with a structure that matches the rotating shaft of the motor, such as a hole, through which the first transmission rod is connected to the rotating shaft of the motor. The second end and the third end of the second transmission rod are provided with a matching structure, such as an axial hole, so that the first transmission rod and the second transmission rod can be pivotally connected together. The fourth end of the second transmission rod is provided with a matching structure, such as an axial hole, so that the second transmission rod and the first air guide plate can be pivotally connected together. Through this arrangement, the side wall of the range hood housing, the first transmission rod, the second transmission rod and the first air guide plate form a four-bar linkage, thereby realizing the function of the first air guide plate being flipped by the rotation of the rotating shaft of the motor through the first transmission rod and the second transmission rod. The structure and working principle of the second flipping mechanism are similar and will not be repeated here.

[0065] The flip mechanism implemented by the motor, the first transmission rod and the second transmission rod has a simple component structure, low processing cost, small weight and volume, which can effectively reduce the weight and manufacturing cost of the range hood 100 and simplify its internal structure.

[0066] Exemplarily, the lifting mechanism may include: a linear motor, which is fixed in the housing of the range hood 100; a slide rail, the slide rail having a fixed part and a sliding part, the fixed part is fixed in the housing of the range hood 100, and the sliding part is connected to the linear motor and the third air guide plate, and the linear motor drives the third air guide plate to rise and fall through the sliding part.

[0067] The lifting mechanism of the range hood 100 is equipped with a linear motor and a slide rail. The linear motor is secured to the housing of the range hood 100 via a threaded connector. The slide rail can be similar to the slide rail used in drawers. The slide rail includes a fixed portion and a sliding portion. The fixed portion is secured to the housing of the range hood 100, for example, via a threaded connector. The sliding portion can be connected to the linear motor and the third air deflector. For example, one end of the sliding portion can be provided with a structure that matches the linear motor's rotating shaft, such as a hole, through which it connects to the linear motor's drive shaft. The other end of the sliding portion can be secured to the third air deflector via three struts and slidably connected to the fixed portion via a slot or other means. When the linear motor's drive shaft extends, it drives the sliding portion to move downward synchronously along the fixed portion's track. The three struts drive the third air deflector to lower, thereby opening the third air inlet. Similarly, when the linear motor's drive shaft retracts, it drives the sliding portion to move upward synchronously along the fixed portion's track. The three struts drive the third air deflector to raise, thereby closing the third air inlet. This arrangement can effectively reduce the noise generated by the third air guide plate during the raising and lowering process, reduce the resistance to movement, and thus reduce the power of the linear motor, thereby achieving the purpose of energy conservation and emission reduction.

[0068] According to an embodiment of the present invention, the control device 120 can be specifically used to: when it is determined based on temperature data that a first condition is met, control the driving mechanism to drive the third air guide plate 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.

[0069] The first temperature threshold may be any appropriate value and may be set as needed, which is not limited in the present invention. For example, the first temperature threshold may be 100° C., 120° C., 150° C., 200° C., and so on.

[0070] Exemplarily, the first air guide plate and the second air guide plate can be regarded as corresponding to the first burner and the second burner, respectively, and the first air guide plate and the second air guide plate can be optionally opened according to the following rules: when the first burner is in use (for example, there is a pot above the first burner), the first air guide plate can be opened first, and the first air inlet can be mainly used for smoking; when the second burner is in use (for example, there is a pot above the second burner), the second air guide plate can be opened first, and the second air inlet can be mainly used for smoking.

[0071] The opening rules for the third air deflector can be configured as needed, with various implementation options possible. In one embodiment, the third air deflector can be controlled to open when the temperature of either the first or second burner exceeds a first temperature threshold. In other words, in this embodiment, it is only necessary to check whether the temperature of either burner exceeds the threshold; it is not necessary for both burners to meet the specified temperature condition simultaneously. With this solution, the third air inlet can be opened promptly when either burner is in use, increasing the air intake and ensuring cleaner extraction of oil fumes.

[0072] For example, when the temperature of the first burner is greater than a certain threshold (i.e., the first temperature threshold), relying solely on the first air inlet to intake air may not be able to effectively absorb oil smoke, so you can choose to open the third air guide plate at this time. In this case, you do not need to consider the temperature of the second burner, that is, regardless of whether the second gas stove corresponding to the second burner is on or not, you can choose to open the third air guide plate. The processing method when the temperature of the second burner is greater than the first temperature threshold is similar and will not be repeated here. Of course, if the temperatures of the first burner and the second burner are both greater than the first temperature threshold, the third air guide plate also needs to be opened.

[0073] It should be noted that, in the case where the air deflector has only two states, open and closed, the term "opening" a particular air deflector herein may refer to placing the air deflector in the only open state. In the case where the angle and / or height of the air deflector are adjustable, the term "opening" a particular air deflector herein may refer to opening the air deflector to a certain angle and / or height (hereinafter collectively referred to as "opening position"), and the specific opening angle and / or height may optionally be determined based on temperature data.

[0074] According to an embodiment of the present invention, the control device 120 can be specifically used to: when the third air guide plate is open, when it is determined based on temperature data that the first condition is not satisfied for a first preset time, control the driving mechanism to drive the third air guide plate to close.

[0075] The first preset time can be any suitable time and can be set as needed, and the present invention is not limited thereto. For example, the first preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the first preset time can be 0.

[0076] It can be understood that the state in which the temperatures of the first furnace head and the second furnace head are both less than or equal to the first temperature threshold is a state in which the first condition is not satisfied.

[0077] The following example uses a first temperature threshold of 200°C and a first preset time of 30 seconds. When the temperature of the first burner exceeds 200°C, the third air deflector is opened. Subsequently, the user may turn off the heat or reduce the power, gradually lowering the temperature of the first burner until it drops below 200°C. If it is determined that the temperature of the first burner has remained below 200°C for more than 30 seconds, the third air deflector may be closed.

[0078] When it is determined that the state in which the first condition is not satisfied continues for the first preset time, the third air guide plate is controlled to be closed. This solution can intelligently and automatically close the air guide plate in a timely manner, and the user experience is better.

[0079] According to an embodiment of the present invention, the control device 120 can be specifically used to: when it is determined based on the temperature data that the second condition is met, control the driving mechanism to drive the third air guide plate to open, wherein the second condition is that the temperature of any one of the first burner 210 and the second burner 220 is greater than the second temperature threshold and the temperature of the other one of the first burner 210 and the second burner 220 is greater than the third temperature threshold.

[0080] In this embodiment, it is necessary to check the temperatures of the two burners at the same time, and only when the temperatures of the two burners are greater than a certain threshold value can the third air guide plate be opened.

[0081] The second temperature threshold and the third temperature threshold can each be any suitable value and can be set as needed, and the present invention is not limited thereto. For example, the second temperature threshold can be 100° C., 120° C., 150° C., 200° C., etc. For example, the third temperature threshold can be 100° C., 120° C., 150° C., 200° C., etc.

[0082] Exemplarily, the second temperature threshold and the third temperature threshold may be equal or unequal.

[0083] In one example, the second temperature threshold is 60° C. and the third temperature threshold is 200° C. That is, the third air guide plate can be opened only when the temperature of one of the first and second burners is greater than 60° C. and the temperature of the other burner is greater than 200° C.

[0084] With this solution, the third air inlet is opened only when the two burners are in use and the temperature reaches a certain threshold to increase the air intake. This can save power to a certain extent and avoid frequently opening and closing the third air guide plate when there is not much oil smoke.

[0085] According to an embodiment of the present invention, the control device 120 can be specifically used to: when the third air guide plate is open, when it is determined based on the temperature data that the second condition is not satisfied for a second preset time, control the driving mechanism to drive the third air guide plate to close.

[0086] The second preset time can be any suitable time and can be set as needed, and the present invention is not limited thereto. For example, the second preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the second preset time can be 0.

[0087] It can be understood that the state in which the temperature of any one of the first burner and the second burner is less than or equal to the smaller of the second temperature threshold and the third temperature threshold, or the temperature of both the first burner and the second burner is less than or equal to the larger of the second temperature threshold and the third temperature threshold, is that the second condition is not met.

[0088] The following description takes the second temperature threshold of 60°C, the third temperature threshold of 200°C, and the second preset time of 30 seconds as an example. When the temperature of the first burner exceeds 60°C and the temperature of the second burner exceeds 200°C, the third air deflector is opened. Subsequently, the user may turn off the fire or reduce the firepower, causing the temperature of the second burner to gradually decrease until it drops below 200°C, while the temperature of the first burner remains constant at around 100°C. Subsequently, if it is determined that the temperatures of the first and second burners are both below 200°C for more than 30 seconds, the third air deflector can be closed.

[0089] When it is determined that the state in which the second condition is not satisfied continues for a second preset time, the driving mechanism is controlled to drive the third air guide plate to close. This solution can intelligently and automatically close the air guide plate in a timely manner, and the user experience is better.

[0090] According to an embodiment of the present invention, the control device 120 can be specifically used to: when it is determined based on the temperature data that the third condition is met, control the driving mechanism to drive the third air guide plate to open, 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 the fourth temperature threshold.

[0091] In this embodiment, it is necessary to check the temperatures of the two burners at the same time, and the third air guide plate is opened only when the sum of the temperatures of the two burners is greater than a certain threshold.

[0092] The fourth temperature threshold may be any appropriate value and may be set as needed, which is not limited in the present invention. For example, the fourth temperature threshold may be 100° C., 120° C., 150° C., 200° C., and so on.

[0093] With this solution, the third air inlet is opened only when the sum of the temperatures of the two burners reaches a certain threshold to increase the air intake. This can save power to a certain extent and avoid frequently opening and closing the third air guide plate when there is not much oil smoke.

[0094] According to an embodiment of the present invention, the control device 120 can be specifically used to: when the third air guide plate is open, when it is determined based on temperature data that the third condition is not satisfied for a third preset time, control the driving mechanism to drive the third air guide plate to close.

[0095] The third preset time can be any suitable time and can be set as needed, and the present invention is not limited thereto. For example, the third preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the third preset time can be 0.

[0096] It can be understood that the state in which the sum of the temperatures of the first furnace head and the second furnace head is less than or equal to the fourth temperature threshold is a state in which the third condition is not satisfied.

[0097] When it is determined that the state in which the third condition is not satisfied continues for a third preset time, the driving mechanism is controlled to drive the third air guide plate to close. This solution can intelligently and automatically close the air guide plate in a timely manner, and the user experience is better.

[0098] According to an embodiment of the present invention, the control device 120 can be specifically used to: when the fourth condition is determined to be met based on the temperature data, control the driving mechanism to drive the first air guide plate to open, wherein the fourth condition is that the temperature of the first furnace head 210 is greater than the fifth temperature threshold; and / or, when the fifth condition is determined to be met based on the temperature data, control the driving mechanism to drive the second air guide plate to open, wherein the fifth condition is that the temperature of the second furnace head 220 is greater than the fifth temperature threshold.

[0099] The fifth temperature threshold can be any suitable value and can be set as needed, and the present invention is not limited to this. For example, the fifth temperature threshold can be 60°C, 80°C, 100°C, 120°C, etc. It is preferable that when the first burner and / or the second burner are in use, the first air guide plate and / or the second air guide plate are opened first, and the third air guide plate is opened only when the air intake of the first air inlet and / or the second air inlet is insufficient. Therefore, it is preferable that among the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fifth temperature threshold, the fifth temperature threshold is the smallest.

[0100] The first and second burners correspond to first and second air deflectors, respectively. The first and second air deflectors can be controlled to open and close based on the temperatures of the first and second burners, allowing the first and second air inlets to draw in fumes generated when the corresponding burners are in use. Compared to a single air inlet, a range hood with both first and second air inlets can also effectively improve extraction efficiency.

[0101] According to an embodiment of the present invention, the control device 120 can be specifically used to: when the first air guide plate is open, when the state in which the fourth condition is not satisfied based on the temperature data continues for a fourth preset time, control the drive mechanism to drive the first air guide plate to close; and / or, when the second air guide plate is open, when the state in which the fifth condition is not satisfied based on the temperature data continues for a fifth preset time, control the drive mechanism to drive the second air guide plate to close.

[0102] The fourth preset time and the fifth preset time can be any suitable time and can be set as needed, and the present invention is not limited thereto. For example, the fourth preset time or the fifth preset time can be 10 seconds, 20 seconds, 40 seconds, 1 minute, 2 minutes, etc. Of course, optionally, the fourth preset time or the fifth preset time can be 0.

[0103] The closing scheme of the first and second air guide plates and their advantages can be understood by referring to the above description of the embodiment of closing the third air guide plate, which will not be described in detail here.

[0104] According to an embodiment of the present invention, the fifth temperature threshold is lower than the first temperature threshold.

[0105] For example, the first temperature threshold may be 200°C, and the fifth temperature threshold may be 60°C. For example, when a user uses a first gas stove, the temperature of the first burner gradually increases. When the temperature of the first burner exceeds 60°C, the first air deflector is opened. Subsequently, if the user increases the heat, such as using high heat mode, the temperature of the first burner may exceed 200°C, at which point the third air deflector may be opened. It is understood that when the temperature of the first burner exceeds 200°C, both the first and third air deflectors are opened.

[0106] According to this embodiment, the first air guide plate and / or the second air guide plate can be opened preferentially, and the third air guide plate can be used as an auxiliary when the air intake is insufficient. This working mode is a more targeted and reasonable oil fume extraction mode.

[0107] According to an embodiment of the present invention, the second temperature threshold is not equal to the third temperature threshold, and the fifth temperature threshold is less than or equal to the smaller one of the second temperature threshold and the third temperature threshold.

[0108] For example, the second temperature threshold and the fifth temperature threshold may be 60°C, and the third temperature threshold may be 200°C. For example, assuming that the user uses the first gas stove and the second gas stove at the same time, when the temperature of the first burner exceeds 60°C, the first air deflector is opened, and when the temperature of the second burner also exceeds 60°C, the second air deflector is opened. If the user adjusts the first gas stove to high fire mode and the second gas stove is still in low fire mode, the temperature of the first burner may exceed 200°C and the temperature of the second burner may exceed 60°C. At this time, the third air deflector can be opened. It can be understood that when the temperature of the first burner exceeds 200°C and the temperature of the second burner exceeds 60°C, the first air deflector, the second air deflector and the third air deflector are all opened.

[0109] Even with both the first and second air deflectors open, it's possible that a burner's temperature still rises too high, preventing both air inlets from drawing in clean fumes. Therefore, you can choose to open the third air deflector. This means you don't have to wait until both burners reach a certain temperature before opening the third air deflector, which can reduce pollution from certain stoves that are prone to producing fumes.

[0110] According to an embodiment of the present invention, the second temperature threshold is equal to the third temperature threshold, and the fifth temperature threshold is smaller than the second temperature threshold and the third temperature threshold.

[0111] For example, the fifth temperature threshold may be 60°C, and the second and third temperature thresholds may be 200°C. For example, assuming a user is using both a first and a second gas stove, the first air deflector is opened when the temperature of the first burner exceeds 60°C, and the second air deflector is opened when the temperature of the second burner also exceeds 60°C. If the user adjusts the first gas stove to high heat mode while the second gas stove is still in low heat mode, the temperature of the first burner may exceed 200°C and the temperature of the second burner may exceed 60°C, at which point the third air deflector will not be opened. If the user adjusts both the first and second gas stoves to high heat mode, the temperature of both the first and second burners may exceed 200°C, at which point the third air deflector may be opened. It is understood that when the temperature of the first burner exceeds 200°C and the temperature of the second burner exceeds 200°C, the first, second, and third air deflectors are all opened.

[0112] Sometimes the air intake of the first and second air inlets is large, which can meet the smoking needs relatively well most of the time. Only when the temperature of the two burners rises to a certain level (for example, two gas stoves enter the stir-fry mode at the same time), it may be impossible to absorb clean oil smoke. At this time, the third air guide plate can be opened, so that the oil smoke can be absorbed in time while saving power consumption as much as possible.

[0113] According to an embodiment of the present invention, the range hood 100 may further include a fan, and the control device 120 may further be used to control the working gear of the fan based on temperature data.

[0114] As described above, the control device 120 can also be used to control the working gear of the fan by controlling the driving current of the main motor. The fan can have any number of working gears, for example, three working gears: high, medium, and low, and different working gears correspond to different fan speeds.

[0115] For example, as the temperature of one or both burners increases, the control device 120 can increase the working level of the fan accordingly. This solution can further provide a larger air intake by adjusting the working level of the fan to absorb oil smoke in a timely manner.

[0116] There are various rules for adjusting the working gear of the fan, and several exemplary implementation schemes are described below.

[0117] According to an embodiment of the present invention, the fan has multiple working gears corresponding to multiple temperature ranges. The control device 120 can be specifically used to: when it is determined based on the temperature data that the temperature of any one of the first burner and the second burner is less than the sixth temperature threshold and the temperature of the other of the first burner and the second burner falls into a specific temperature range among the multiple temperature ranges, control the fan to operate at the working gear corresponding to the specific temperature range; when it is determined based on the temperature data that the temperature of any one of the first burner and the second burner falls into the first temperature range among the multiple temperature ranges and the temperature of the other of the first burner and the second burner falls into the second temperature range among the multiple temperature ranges, control the fan to operate at the working gear corresponding to the first temperature range, or the second temperature range, or any temperature range between the first temperature range and the second temperature range.

[0118] The sixth temperature threshold can be any suitable value and can be set as needed, and the present invention is not limited thereto. For example, the sixth temperature threshold can be 60°C, 80°C, 100°C, 120°C, etc. In one example, the sixth temperature threshold is equal to the fifth temperature threshold, for example, both the sixth temperature threshold and the fifth temperature threshold are 60°C. In the embodiment where the sixth temperature threshold is equal to the fifth temperature threshold, when the temperature of any burner is less than the sixth temperature threshold, the air deflector corresponding to the burner is closed. At this time, only the temperature of the other burner can be considered, and the corresponding working gear can be selected according to the temperature range within which the temperature of the other burner falls.

[0119] For example, assume that the fan has three operating gears: low, medium, and high, corresponding to the following three temperature ranges, respectively: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C. In one example, when the temperature of the first burner is less than 60°C, the first air guide plate is not opened. At this time, if the temperature of the second burner is greater than or equal to 60°C and less than 150°C, the second air guide plate may be opened and the fan is controlled to operate at low gear. If the temperature of the second burner is greater than or equal to 150°C and less than 200°C, the second air guide plate may be opened and the fan is controlled to operate at medium gear. If the temperature of the second burner is greater than or equal to 200°C, the second air guide plate may be opened and the fan is controlled to operate at high gear.

[0120] In another example, when the temperature of the first burner is greater than or equal to 60°C and less than 150°C, and the temperature of the second burner is greater than or equal to 200°C, the first and second air deflectors may be opened, and the fan may be controlled to operate at one of low, medium, and high settings. Preferably, the fan operating setting may be determined based on the temperature range within which the temperature of the higher-temperature burner falls. For example, in the above example, the fan may be controlled to operate at high setting.

[0121] Through the above solution, the working gear of the fan can be adjusted as the temperature of any one or two burners rises or falls. At the same time, by coordinating the switch of the air guide plate, the air intake volume can be adjusted more flexibly.

[0122] According to an embodiment of the present invention, the first air guide plate has multiple first opening positions corresponding to multiple temperature ranges. The control device 120 can be specifically used to: when it is determined based on temperature data that the temperature of the first furnace head falls into a specific temperature range among multiple temperature ranges, the control driving mechanism drives the first air guide plate to open to the first opening position corresponding to the specific temperature range.

[0123] The first opening position may include the angle and / or height of the first air deflector. For example, the first air deflector and / or the second air deflector may be flippable between an open position and a closed position. The air deflectors can be opened to different angles to adjust the ventilated area of ​​the air inlet. The third air deflector may be a liftable air deflector that can be raised or lowered to different heights to adjust the distance between the air inlet and the air deflector.

[0124] Exemplarily, the first opening position may refer to the angle of the first air deflector. For example, the first air deflector may have three opening positions, i.e., three opening angles: a first angle, a second angle, and a third angle, which respectively correspond to the following three temperature ranges: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C.

[0125] In one example, if the temperature of the first burner is greater than or equal to 60°C and less than 150°C, the driving mechanism can be controlled to drive the first air guide plate to open to a first angle; if the temperature of the first burner is greater than or equal to 150°C and less than 200°C, the driving mechanism can be controlled to drive the first air guide plate to open to a second angle; if the temperature of the first burner is greater than or equal to 200°C, the driving mechanism can be controlled to drive the first air guide plate to open to a third angle.

[0126] Through the above solution, the opening position of the first air guide plate can be adjusted as the temperature of the first furnace head rises and falls, so that the air intake volume can be adjusted more flexibly.

[0127] According to an embodiment of the present invention, the second air guide plate has multiple second opening positions corresponding to multiple temperature ranges. The control device 120 can be specifically used to: when it is determined based on temperature data that the temperature of the second furnace head falls into a specific temperature range among multiple temperature ranges, the control driving mechanism drives the second air guide plate to open to the second opening position corresponding to the specific temperature range.

[0128] The second opening position may include an angle and / or height of the second air deflector. As described above, the second air deflector may be a deflector that can be flipped between a flip-open position and a flip-closed position.

[0129] For example, the second air guide plate can have three working positions, i.e., three opening angles: a first angle, a second angle, and a third angle, which correspond to the following three temperature ranges respectively: greater than or equal to 60°C and less than 150°C, greater than or equal to 150°C and less than 200°C, and greater than or equal to 200°C.

[0130] In one example, when the temperature of the second burner is greater than or equal to 60°C and less than 150°C, the drive mechanism can be controlled to drive the second air guide plate to open to a first angle. If the temperature of the second burner is greater than or equal to 150°C and less than 200°C, the drive mechanism can be controlled to drive the second air guide plate to open to a second angle. If the temperature of the second burner is greater than or equal to 200°C, the drive mechanism can be controlled to drive the second air guide plate to open to a third angle.

[0131] Through the above solution, the opening position of the second air guide plate can be adjusted as the temperature of the second furnace head rises and falls, so that the air intake volume can be adjusted more flexibly.

[0132] According to an embodiment of the present invention, the pyroelectric module 110 is located in the middle of the top of the range hood 100, so that the temperatures of the two burners can be detected more evenly and the temperature detection error can be reduced. Figure 2, showing the location of the pyroelectric module. Optionally, the pyroelectric module 110 can be located at any location as long as its temperature detection range can cover the first burner and the second burner.

[0133] Optionally, the pyroelectric module 110 may include one or more pyroelectric infrared sensors. Because pyroelectric infrared sensors have a wide temperature detection range, a single pyroelectric infrared sensor is generally sufficient to detect the temperatures of both burners, effectively saving costs. Of course, multiple pyroelectric infrared sensors may also be provided as needed. For example, two pyroelectric infrared sensors may be installed above the first burner and the second burner, respectively, with the first pyroelectric infrared sensor used to detect the temperature of the first burner and the second pyroelectric infrared sensor used to detect the temperature of the second burner.

[0134] According to an embodiment of the present invention, the range hood 100 may further include an input component for receiving air deflector indication information input by a user for indicating the opening and closing of the air deflectors in the air deflector assembly 130. The control device 120 is connected to the input component. The control device 120 may also be used to control the driving mechanism to drive each air deflector to open and close based on the air deflector indication information.

[0135] Exemplarily, the input component may be any hardware capable of receiving user commands, such as one or more of a keyboard, a mouse, a microphone, and a touch screen. Exemplarily, the input component may also be a wired or wireless communication component configured to receive user-input wind deflector indication information transmitted from an external device. The external device may be a personal computer, a mobile terminal, a server, or the like.

[0136] For example, the range hood's on / off control panel may be provided with multiple air deflector control buttons, such as three air deflector control buttons, each for controlling the opening and closing of the three air deflectors. For example, if a user presses the first air deflector control button, the drive mechanism may be controlled to open the first air deflector. If the user presses the first air deflector control button again, the drive mechanism may be controlled to close the first air deflector.

[0137] An input component is provided for the user so that the user can manually control the opening and closing of each air deflector when needed, so that the user can have greater control freedom and a better user experience.

[0138] Exemplarily, the input component can also be used to receive mode indication information input by the user to indicate the automatic control mode, and the control device 120 can also be used to receive temperature data collected by the thermal release module 110 in response to the reception of the mode indication information, and control the driving mechanism to drive each air guide plate to open and close based on the temperature data.

[0139] For example, the input component 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 activated, and the user can control the opening and closing of each air deflector via the air deflector control button. When the user presses the manual / automatic control button again, the automatic mode is activated, and the control device 120 can begin to read temperature data and control the opening and closing of each air deflector based on the temperature data.

[0140] According to an 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, and the second chip 124 is integrated on the power board 150. The first chip 122 is connected to the thermal release module 110 for receiving temperature data and transmitting the temperature data to the second chip 124; the second chip 124 is connected to the driving mechanism for receiving temperature data and controlling the driving mechanism to drive each air guide plate to open and close based on the temperature data.

[0141] Return to see Figure 1 , showing the switch control panel 140 and the power panel 150. The switch control panel 140 can be set on the front of the range hood 100 and is mainly used for user interaction. For example, the user can input instructions through the buttons on the switch control panel 140 (such as the above-mentioned air deflector control button, manual / automatic control button, etc.), and can also view information related to the range hood (such as the working gear of the fan, etc.) through the LED display device on the switch control panel 140.

[0142] The power board 150 can be located within the housing of the range hood 100 and is primarily used to power the various components of the range hood. The power board 150 may include power circuitry and a motor drive circuit for the main motor. The first chip 122 and the second chip 124 are integrated into the switch control board 140 and the power board 150, respectively, and can communicate via wired or wireless means.

[0143] Preferably, the pyroelectric module 110 is also disposed on the front of the range hood 100 to facilitate detection of the first and second burners. Therefore, the pyroelectric module 110 can be connected to the first chip 122, and transmit temperature data via the first chip 122 to the second chip 124, which then controls the opening and closing of the air deflector.

[0144] Separating the control device facilitates the distributed layout of the components of the range hood 100 and reduces the impact between circuits. In addition, this separation solution can be well adapted to the conventional range hood architecture, thereby reducing development costs.

[0145] An exemplary air intake control method of the range hood 100 is described below in conjunction with Table 1. Table 1 is a table of the correspondence between the burner temperature, the fan operating gear and the air guide plate switch status. In the embodiment shown in Table 1, the fan operating gear is divided into two gears, low and high, and the three air guide plates have only two states, open and closed. In Table 1, the left temperature refers to the temperature of the left burner (i.e., the first burner), and the right temperature refers to the temperature of the right burner (i.e., the second burner). Observing Table 1, it can be seen that when the temperature of the left burner or the right burner is greater than 60°C, the corresponding left air guide plate or right air guide plate is opened (see the above embodiment related to the fifth temperature threshold). The middle air guide plate is only opened when the temperature of one of the left and right burners is greater than 60°C and the temperature of the other is greater than 200°C (see the above embodiment related to the second temperature threshold and the third temperature threshold). When only one burner is in use (the temperature of the other burner does not exceed 60°C), the fan selects an operating gear based on the temperature range of the burner: low gear is used if the temperature does not exceed 200°C, and high gear is used if the temperature exceeds 200°C (see the above embodiment related to the sixth temperature threshold). When two burners are in use (the temperature of both burners exceeds 60°C), the fan selects high gear only when the temperature of both burners exceeds 200°C; low gear is used otherwise.
