Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a control method, control device, kitchen appliance, and readable storage medium. Background Technology

[0002] With the development of intelligent kitchen appliances, automatic speed-adjustable range hoods have gradually become the industry mainstream. Most range hood products use several sensors to detect physical quantities related to the cooking process, such as dust, organic matter, temperature, and sound, and convert them into oil fume concentration through corresponding algorithms, adjusting the fan's operating state accordingly. Most products are manufactured with one or more preset speed adjustment curves for users to choose from. However, in actual application, users with different cooking habits have different tolerances for oil fumes, and will expect different fan speeds for the same amount of smoke, meaning that fixed speed adjustment curves do not meet user needs. Summary of the Invention

[0007] Based on the obtained manual speed adjustment operation, the current speed adjustment curve is processed to obtain the adjustment curve;

[0008] The operation of the kitchen appliances is controlled using the aforementioned adjustment curve.

[0009] In the above control method, when the speed adjustment curve is selected to control the operation of kitchen appliances based on the concentration of oil fumes, a manual speed adjustment operation is obtained. The speed adjustment curve is then processed based on the manual speed adjustment operation to obtain an adjustment curve, so that users can adjust the speed adjustment curve of kitchen appliances according to their own habits or preferences, thus meeting user needs.

[0017] When the manual speed adjustment operation is a downshift operation, a speed adjustment curve with a slope less than the current speed adjustment curve is selected as the adjustment curve.

[0018] In some implementations, the current speed control curve is processed based on the acquired manual speed control operation to obtain an adjustment curve, including:

[0019] If the manual speed adjustment operation is an upshift operation and the slope of the current speed adjustment curve is the largest among the slopes of the plurality of speed adjustment curves, increase the slope of the current speed adjustment curve to obtain the adjustment curve.

[0020] If the manual speed adjustment operation is a downshift operation and the slope of the current speed adjustment curve is the smallest among the slopes of the plurality of speed adjustment curves, the slope of the current speed adjustment curve is reduced to obtain the adjustment curve.

[0021] In some embodiments, the control method includes:

[0022] If the obtained manual speed adjustment operation is a mistake, the manual speed adjustment operation will be discarded.

[0025] The control module is used to select one of the multiple speed control curves based on the oil fume concentration and control the operation of kitchen appliances using the selected speed control curve;

[0026] The adjustment module is used to process the current speed adjustment curve based on the obtained manual speed adjustment operation to obtain the adjustment curve;

[0027] The control module is used to control the operation of the kitchen appliances using the adjustment curve.

[0028] A kitchen appliance according to an embodiment of the present invention includes a control device and a fan as described in the above embodiment, wherein the control device is electrically connected to the fan.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for mutual communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0043] Please combine Figure 1 and Figure 2 One control method according to an embodiment of the present invention includes:

[0044] Step S12: Obtain the oil fume concentration based on the oil fume data output by the oil fume sensor 10;

[0045] Step S14: Select one of the multiple speed control curves and control the operation of the kitchen appliances according to the selected speed control curve and the oil fume concentration;

[0046] Step S16: Based on the obtained manual speed adjustment operation, process the current speed adjustment curve to obtain the adjustment curve;

[0047] Step S18: Use the adjustment curve to control the operation of kitchen appliances.

[0048] In the above control method, when the speed adjustment curve is selected to control the operation of kitchen appliances based on the concentration of oil fumes, a manual speed adjustment operation is obtained. The speed adjustment curve is then processed based on the manual speed adjustment operation to obtain an adjustment curve, so that users can adjust the speed adjustment curve of kitchen appliances according to their own habits or preferences, thus meeting user needs.

[0049] Specifically, the fume sensor 10 can be installed on the kitchen appliance or in other locations outside the appliance, such as on a wall. The fume sensor 10 can be wired or wirelessly connected to the controller 16 of the kitchen appliance, enabling the controller 16 to acquire the fume data output by the sensor 10, calculate the fume concentration based on this data, and then select a speed control curve from multiple speed control curves that matches the fume concentration to control the fan operation, such as controlling the fan speed, current, or voltage. Wireless connection methods include, but are not limited to, Bluetooth, infrared, WIFI, ZigBee, and NFC.

[0050] Kitchen appliances include range hoods, integrated cooktops, and other appliances with fume extraction functions. It's understandable that a range hood can be a variable frequency range hood. An integrated cooktop includes a range hood, which can also be a variable frequency range hood. Figure 2 In the example, the kitchen appliance is a range hood. The range hood can be a top-exhaust, bottom-exhaust, or side-exhaust type; no specific limitation is made here. The kitchen appliance includes a power board 12 and a fan 14. The power board 12 is electrically connected to a controller 16 and the fan 14. The controller 16 is connected to a fume sensor 10. When the fan 14 is working, it rotates its blades to suck up the fumes. The controller 16 performs logical processing on the fume data collected by the fume sensor 10 to determine the speed control curve and sends instructions (including the speed control curve) to the power board 12. The power board 12 then drives the fan 14 and other loads to operate, thus sucking up the fumes. The rotational speed of the fan 14 determines the exhaust speed, or the fume suction power. The controller 16 can be installed on a main control board, a computer board, or a control board.

[0051] The fume sensor 10 can be set according to a pre-calibrated position. For example, the fume sensor 10 can be set in the smoke inlet of the range hood, the air outlet of the fan 14 volute, or the flue of the check valve, etc. No specific limitation is made here.

[0052] It is understandable that the oil fume sensor 10 can be set in multiple locations on the range hood, and the oil fume size data collected by multiple oil fume sensors 10 can be processed (such as taking the average value, or assigning different weights according to different locations and calculating through the weights) to obtain the final oil fume size.

[0053] It is understandable that, in order to reduce the degree of contamination of the fume sensor 10 by oil fumes, a shielding structure or sealing structure can be set on the outside or inside of the fume sensor 10 to reduce the adhesion of oil fumes to the optical components or sensor. The fume sensor 10 can be fixed to the range hood by means of screw fixing, interference fit, snap-fit, welding, etc.

[0054] The range hood has speed control buttons on its body, allowing users to adjust the fan speed 14 to their desired suction power. Users can manually adjust the speed by using these buttons. These buttons can include touchscreens, buttons, knobs, and sliders, and include buttons for increasing and decreasing speed. Manual speed adjustment can also be input via a terminal that communicates with the kitchen appliance. Terminals include, but are not limited to, mobile phones, tablets, personal computers, smart wearable devices, and remote controls. Users can perform manual speed adjustments through the terminal's application interface, and the resulting adjustments are transmitted to the kitchen appliance. Alternatively, manual speed adjustment can also be input via voice. For example, users can speak to the kitchen appliance or terminal, such as saying "increase fan speed," "upgrade," or "increase airflow." The kitchen appliance or terminal receives the voice command to indicate the desired speed increase.

[0055] Please combine Figure 3 In the illustrated embodiment, the kitchen appliance has eight built-in speed control curves, numbered L1, L2, L3, L4, ..., L8 from bottom to top. The slope of the speed control curves gradually increases from L1 to L8, meaning the voltage of the fan 14 becomes increasingly sensitive to the concentration of cooking fumes. The horizontal axis of the speed control curve represents the concentration of cooking fumes, and the vertical axis represents the voltage of the fan 14. In other words, the speed control curves express the relationship between the voltage of the fan 14 and the concentration of cooking fumes. Typically, the kitchen appliance can default to using one of the speed control curves for airflow control. For example, it can default to using speed control curve L4 to control the airflow. Based on the collected concentration of cooking fumes, the corresponding voltage of the fan 14 is obtained according to speed control curve L4, thereby controlling the operation of the fan 14.

[0056] It is understood that in other embodiments, the speed regulation curve can also be the relationship between the current of the fan 14 and the oil fume concentration, the rotational speed of the fan 14 and the oil fume concentration, or the power of the fan 14 and the oil fume concentration; no specific limitation is made here. The speed regulation curve essentially represents the relationship between the oil fume concentration and the air volume of the fan 14, with the aim of meeting the needs of different operating conditions.

[0057] In some implementations, multiple speed control curves can be pre-stored locally on the kitchen appliance at the factory. This allows for adaptive control of the fan 14's airflow even if the kitchen appliance is not connected to the internet.

[0058] In some implementations, the control method further includes:

[0059] Multiple speed control curves are retrieved from the server and updated in the kitchen appliances. This allows the speed control curves of the kitchen appliances to be updated.

[0060] Specifically, multiple speed control curves can be pre-stored on a server (cloud) when the kitchen appliance leaves the factory. When the kitchen appliance is connected to the network for the first time, multiple speed control curves can be downloaded from the server and stored in the kitchen appliance to update the speed control curves of the kitchen appliance.

[0061] Kitchen appliances can be set to an automatic mode. When the user uses the automatic mode, the kitchen appliance first reads the speed regulation curve from the cloud, then configures it into the local control program of the kitchen appliance. Next, it calculates the oil fume concentration, and then controls the operation of the kitchen appliance according to the speed regulation curve corresponding to the oil fume concentration to match the air volume.

[0062] In some implementations, the control method further includes:

[0063] The adjustment curve is uploaded to the server for storage. This allows kitchen appliances to access the latest speed adjustment curves set by the user.

[0064] Specifically, in this embodiment of the invention, the kitchen appliance automatically optimizes the speed control curve based on the user's manual intervention in automatic mode to obtain an adjustment curve, and synchronizes the adjustment curve to the server for long-term big data statistics, providing a foundation for deep habit learning. During user operation, the overall performance of the kitchen appliance increasingly approximates the user's expectations, giving each device its own unique characteristics and improving product satisfaction.

[0065] In some embodiments, the fume sensor 10 includes at least one of a light sensor and an organic molecule sensor. Thus, the selection of the fume sensor 10 is flexible.

[0066] Specifically, the fume sensor 10 can be a light sensor, which includes a light emitting unit and a light receiving unit. In one embodiment, the light emitting unit and the light receiving unit can be arranged opposite to each other. When the fume sensor 10 is working, the light emitting unit emits light (such as infrared light) that passes through the fume in the flue, and the light receiving unit receives the light emitted by the light emitting unit that has passed through the fume. Due to the obstruction of the fume, the intensity of the light received by the light receiving unit is negatively correlated with the size of the fume. By pre-calibrating this negative correlation, the real-time size of the fume can be obtained, and the controller 16 controls the speed of the fan 14 according to the size of the fume to obtain a fume extraction capacity that matches the size of the fume. In addition, the number of light emitting units and light receiving units can be single, or one light emitting unit can correspond to two or more light receiving units.

[0067] In another embodiment, the light emitting unit and the light receiving unit can be arranged at a certain angle. When the fume sensor 10 is working, the light emitting unit emits light (such as infrared light) which is incident on the fumes in the flue, and the light receiving unit receives the light reflected by the fume particles. Since the more fumes there are, the more light emitted by the light emitting unit is reflected, the intensity of the light received by the light receiving unit is positively correlated with the size of the fumes. By pre-calibrating this positive correlation, the real-time size of the fumes can be obtained, and the controller 16 controls the speed of the fan 14 according to the size of the fumes to obtain a fume extraction capacity that matches the size of the fumes.

[0068] The fume sensor 10 can also be an organic molecule sensor (VOC sensor). The VOC sensor has a collection opening. When oil fumes are generated, they diffuse into the VOC sensor through the collection opening. The VOC sensor detects the organic gas components in the oil fumes, thereby determining the real-time oil fume level. The controller 16 controls the speed of the fan 14 according to the oil fume level to obtain the oil fume extraction capacity that matches the oil fume level.

[0069] The oil fume sensor 10 can also employ a light sensor and an organic molecule sensor. The light sensor and the organic molecule sensor can be set to different positions to obtain the oil fume depth at the corresponding positions. The final oil fume concentration can be the average value of the oil fume concentration detected by the light sensor and the organic molecule sensor, or a value calculated according to different weights.

[0070] In some implementations, the current speed control curve is processed based on the acquired manual speed control operation to obtain an adjustment curve, including:

[0071] When the manual speed adjustment operation is in the upshift mode, select the speed adjustment curve with a slope greater than the current speed adjustment curve as the adjustment curve.

[0072] When manually adjusting the speed to a lower gear, select a speed curve with a slope less than the current speed curve as the adjustment curve. This allows you to obtain an airflow that matches the user's needs, thus satisfying their requirements.

[0073] Specifically, please combine Figure 3 When the user selects the automatic mode, the kitchen appliances use the speed control curve L4 by default and control the operation of the kitchen appliances according to the depth of oil fumes, such as controlling the voltage of the fan 14 to obtain the corresponding air volume.

[0074] When a manual speed adjustment is requested, it indicates that the user wants to control the current airflow. If the manual speed adjustment is set to increase the speed, it means the user wants to increase the airflow. In this case, an alternative speed adjustment curve can be selected, such as speed adjustment curve L5 or L6. The slope of the selected speed adjustment curve should be greater than that of the current speed adjustment curve. In other words, for the same depth of cooking fumes, the speed adjustment curve with the larger slope corresponds to a larger airflow. The selected speed adjustment curve will be used as the adjustment curve.

[0075] It should be noted that if the obtained manual leveling operation is to increase the speed by one gear, then based on the speed adjustment curve L4, select speed adjustment curve L5 as the adjustment curve. If the obtained manual leveling operation is to increase the speed by two gears, then based on speed adjustment curve L4, select speed adjustment curve L6 as the adjustment curve, and so on.

[0076] When the manual speed adjustment is set to downshift, it indicates that the user wants to reduce the airflow. In this case, an alternative speed adjustment curve can be selected, such as speed adjustment curve L3 or L2. The slope of the selected speed adjustment curve is less than that of the current speed adjustment curve. In other words, for the same depth of cooking fumes, the speed adjustment curve with a smaller slope corresponds to a smaller airflow. The selected speed adjustment curve serves as the adjustment curve.

[0077] It should be noted that if the obtained manual leveling operation is to downshift by one gear, then based on the speed regulation curve L4, select speed regulation curve L3 as the adjustment curve. If the obtained manual leveling operation is to downshift by two gears, then based on speed regulation curve L4, select speed regulation curve L2 as the adjustment curve, and so on.

[0078] It is understood that in other implementations, the direction of gear adjustment (upshifting or downshifting) is determined based on the manual speed adjustment operation, and a suitable speed adjustment curve is selected using a binary method. For example, in the case of upshifting, the slope of the current speed adjustment curve is doubled to obtain the adjustment curve, and in the case of downshifting, the slope of the current speed adjustment curve is halved to obtain the adjustment curve.

[0079] In some implementations, the current speed control curve is processed based on the acquired manual speed control operation to obtain an adjustment curve, including:

[0080] When the manual speed adjustment operation is upshifting and the slope of the current speed adjustment curve is the largest among multiple speed adjustment curves, increase the slope of the current speed adjustment curve to obtain the adjustment curve.

[0081] When manual speed adjustment is in the downshifting mode and the slope of the current speed adjustment curve is the smallest among multiple speed adjustment curves, the slope of the current speed adjustment curve is reduced to obtain an adjustment curve. In this way, an airflow that matches the user's needs can be obtained, thus satisfying the user's requirements.

[0082] Specifically, if the current speed control curve has the steepest slope among all speed control curves, and the user continues to increase the speed, the adjustment curve is obtained by increasing the slope of the speed control curve with the steepest slope. For example, the slope of the adjustment curve with the steepest slope is multiplied by a coefficient greater than 1. For instance, if the current speed control curve is L8, and the slope K8 of speed control curve L8 is the steepest, when the user continues to increase the speed, the slope K8 of speed control curve L8 is multiplied by 1.2 to obtain the adjustment curve, and the slope of the adjustment curve is K8*1.2. It is understood that an upper limit value for the slope can be set. When the slope of the adjustment curve calculated based on the speed increase operation is greater than the upper limit value, the slope of the current speed control curve remains unchanged. Optionally, the kitchen appliance can issue an audible and / or visual warning that the airflow cannot be increased further.

[0083] If the current speed control curve has the smallest slope among all speed control curves, and the user continues to perform a downshift operation, the speed control curve with the smallest slope will be reduced to obtain the adjustment curve. For example, the slope of the adjustment curve with the smallest slope will be multiplied by a coefficient less than 1 to obtain the adjustment curve. For instance, if the current speed control curve is L1, and the slope K1 of speed control curve L1 is the smallest, when the user continues to perform a downshift operation, the slope K1 of speed control curve L1 will be multiplied by 0.8 to obtain the adjustment curve, and the slope of the adjustment curve will be K1*0.8. It is understood that a lower limit value for the slope can be set. When the slope of the adjustment curve calculated based on the downshift operation is less than the lower limit value, the slope of the current speed control curve remains unchanged. Optionally, the kitchen appliance can issue an audible and / or visual warning that the fan speed cannot be further reduced.

[0084] In some implementations, the control method includes:

[0085] If a manual speed adjustment operation is detected as a mistake, it will be removed. This allows for a more accurate assessment of user habits or preferences.

[0086] Specifically, a misoperation might be an action triggered by the user unintentionally. For example, a user might intend to downshift, but after pressing the upshift button, realize their mistake, and immediately press the downshift button instead. This type of operation can be considered a misoperation.

[0087] Therefore, in one embodiment, if a manual speed adjustment operation is first obtained, and then another one or more manual speed adjustment operations are obtained within a preset time period, and one of these second or third manual speed adjustment operations is the opposite of the first obtained manual speed adjustment operation, then these manual speed adjustment operations can be considered as erroneous operations and discarded. The specific value of the preset time period can be obtained based on empirical values ​​or through testing and simulation.

[0088] In one example, when a kitchen appliance is operating in automatic mode with speed control curve L4, it receives an increase speed operation at time T0, and within a preset time period T, it receives a decrease speed operation, or several manual speed control operations including a decrease operation. At this point, the kitchen appliance considers the manual speed control operations received between T0 and T0+T as erroneous operations and discards them. That is, the kitchen appliance does not respond to these manual speed control operations and continues to operate with speed control curve L4.

[0089] Please refer to Figure 4 A control device 200 according to an embodiment of the present invention includes:

[0090] The acquisition module 22 is used to acquire the oil fume concentration based on the oil fume data output by the oil fume sensor 10;
