Description

Technical Field

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

[0002] As living standards improve, consumers are paying more and more attention to the kitchen environment. During cooking, harmful gases are inevitably produced, polluting the kitchen. Therefore, kitchen appliances capable of detecting and promptly venting these harmful gases outdoors have emerged.

[0003] Currently, the common method for detecting cooking fumes is to use an infrared emitter and receiver in combination. This method detects fumes by observing how they block or scatter infrared light. However, because the path of infrared light is narrow, if objects such as hands or cookware are in the path of the infrared light, the receiver will not be able to receive the infrared light, resulting in the infrared detection method failing to detect cooking fumes properly. Summary of the Invention

[0009] In some embodiments, determining the smoke concentration data based on the output data of the color sensor includes:

[0010] The color change value is output based on the difference between the real-time detection value output by the color sensor and the initial reference value.

[0011] The smoke concentration data is determined based on the correspondence between the color change value and the pre-stored color change value and the smoke concentration data.

[0012] In some embodiments, the initial reference value is the first stable value detected by the color sensor of the environment surrounding the kitchen appliance after the color sensor is powered on, or

[0020] In some implementations, determining the operating parameters of the fan based on the oil fume scenario includes:

[0021] If the fume scenario is determined to be a low-fume scenario, the fan is controlled to operate at a low speed.

[0022] In some implementations, determining the operating parameters of the fan based on the oil fume scenario includes:

[0023] If the fume scenario is determined to be a high-fume scenario, the fan is controlled to operate at a high speed.

[0024] In some embodiments, the kitchen appliance includes an alarm device, the fume scenario includes an abnormal fume scenario, and the control method includes: when it is determined that the fume scenario is an abnormal fume scenario, controlling the alarm device to sound an alarm.

[0025] In some implementations, when the temperature of the cookware exceeds a preset temperature and the smoke concentration data exceeds a preset concentration, the oil fume scenario is determined to be an abnormal oil fume scenario, or

[0026] When the smoke concentration data exceeds a preset concentration, the oil fume scenario is determined to be an abnormal oil fume scenario.

[0028] The oil fume scenario is determined based on the smoke concentration data.

[0029] The operating parameters of the fan are determined based on the described oil fume scenario.

[0030] In some embodiments, the color sensor includes a housing, a color sensing component, and a convex lens. The housing has a receiving cavity, the color sensing component is installed in the receiving cavity, and the housing also has an exposure opening for exposing the color sensing component. The convex lens is located on the color sensing component and covers the exposure opening.

[0045] 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.

[0046] Please see Figure 1 as well as Figure 2 The control method of this invention is used in a kitchen appliance 100. The kitchen appliance 100 includes a fan 20 and a color sensor 30. The control method includes the following steps:

[0047] S10, determine the smoke concentration data based on the output data of the color sensor;

[0048] S20, determines the oil fume scenario based on smoke concentration data;

[0049] S30 determines the operating parameters of the fan based on the oil fume scenario.

[0050] Please see Figure 3The kitchen appliance 100 of this invention includes a controller 10, a fan 20, and a color sensor 30. The controller 10 is connected to the fan 20 and the color sensor 30. The controller 10 is used to acquire smoke concentration data output by the color sensor 30, to determine the oil fume scenario based on the smoke concentration data, and to determine the operating parameters of the fan 20 based on the oil fume scenario.

[0051] In other words, the control method of the embodiments of the present invention can be implemented by the kitchen appliance 100 of the embodiments of the present invention. Specifically, the control method of the embodiments of the present invention can be implemented by the controller 10.

[0052] The kitchen appliance 100 and control method of this invention determine the current oil fume scene based on the smoke concentration data determined by the output data of the color sensor 30, and then determine the operating parameters of the fan 20 according to the oil fume scene. For different oil fume scenes, the fan 20 operates with different parameters, which effectively improves the oil fume extraction effect. In addition, when light is incident on the color sensor 30, the color sensor 30 can detect the color, thereby realizing the determination of the current oil fume scene based on the smoke concentration data. Therefore, this invention can also effectively reduce the impact of human hands, cookware and other items on the accuracy of oil fume detection.

[0053] Specifically, in step S10, the number of color sensors 30 can be one or more, such as two, three, four, five, or other numbers. It is worth noting that when there are multiple color sensors 30, their detection ranges can partially or completely overlap. In this case, the average value of the oil fume data output by the color sensors 30 with overlapping detection ranges can be used as the current smoke concentration data. Alternatively, the oil fume data output by the color sensors 30 with overlapping detection ranges can be weighted to calculate the current smoke concentration data. The detection ranges of the color sensors 30 can also not overlap. For example, the detection range of some color sensors 30 may cover the stove burner or cookware to directly detect the location where oil fumes are generated, while the detection range of other color sensors 30 may include locations around the kitchen appliance 100 that do not directly generate oil fumes, in order to detect the dispersion of oil fumes. The specific number of color sensors 30 and the specific method for determining the current smoke concentration data can be adjusted according to production costs, detection accuracy, and other needs, and are not specifically limited here.

[0054] It is worth noting that in related technologies, infrared light detection methods require an infrared receiver to receive infrared light emitted by an infrared transmitter in order to achieve the function of detecting oil fumes. This means that infrared detection methods cannot directly detect the locations where oil fumes are generated, such as stove burners and cookware. It is necessary to wait for the oil fumes to dissipate into the infrared detection range before detection can be achieved. However, the embodiment of this invention uses a color sensor 30, which can directly detect the locations where oil fumes are generated, such as stoves and cookware, effectively shortening the oil fume detection time and speeding up the response speed of the kitchen appliance 100 to oil fumes.

[0055] In step S20, according to this embodiment of the invention, smoke concentration data is determined based on the output data of the color sensor 30 to determine the oil fume scenario. Specifically, based on the smoke concentration data, common kitchen scenarios in actual operation are divided into the following oil fume scenarios:

[0056] Smoke-free scenarios, low-fume scenarios, and high-fume scenarios.

[0057] The "smokeless scenario" corresponds to a situation where there is no oil fume concentration when the stove is not lit, or a situation where no oil fume is produced after the stove is lit. The "low oil fume scenario" corresponds to situations with low oil fume concentration, such as heating a pan or simmering over low heat. The "high oil fume scenario" corresponds to situations with high oil fume concentration, such as stir-frying or deep-frying over high heat. This classification of oil fume scenarios provides a basis for determining the operating parameters of the fan 20.

[0058] In step S30, in this embodiment, the operating parameters of the fan 20 may include the fan 20 speed setting. Different speed settings of the fan 20 can provide different air volumes. It is understood that different air volumes result in different suction power from the kitchen appliance 100, allowing the kitchen appliance 100 to provide a good smoke extraction effect in various oil fume environments. The fan 20 speed setting may include off, low, and high. When the fan 20 is in the off position, the fan 20 does not work. When the fan 20 is in the low speed position, the fan 20 operates at low power with a lower speed, and the kitchen appliance 100 provides less suction power. When the fan 20 is in the high speed position, the fan speed is higher, the fan 20 operates at high power, and the kitchen appliance 100 provides greater suction power. It is worth noting that the standards for low-power and high-power operation of the fan 20 are not fixed and can be adjusted according to user needs and actual usage conditions, etc., and are not specifically limited here.

[0059] Of course, the 20-speed fan can also include medium speed, variable speed, or multiple refined high speeds under the high speed. These can be added or removed as needed, and no specific restrictions are made here.

[0060] In some implementations, please refer to Figure 4 S10 includes:

[0061] S11: Output the color change value based on the difference between the real-time detection value output by the color sensor and the initial reference value;

[0062] S12: Determine the smoke concentration data based on the correspondence between the color change value and the pre-stored color change value and smoke change value.

[0063] Specifically, in this embodiment, the color sensor 30 represents the color of the received incident light by the ratio and intensity of red, green, and blue light. The detection value or reference value may include at least one of the ratio and intensity of red, green, and blue light. By comparing the difference between the initial reference value and the real-time detection value, the color change value is obtained. Different smoke concentration data will result in different colors, so the smoke concentration data can be deduced from the color change value.

[0064] There are many ways to derive the correspondence between color change values ​​and smoke concentration data, which can be obtained through simulation, field measurement, and other methods. Specific methods will not be elaborated here. Furthermore, the color change value can include not only the color change value within the current sampling period but also the rate of change of the color change value across different sampling periods. This rate can be set as needed and is not specifically limited here. The sampling period can be 50 milliseconds, 1 second, 1 minute, 5 minutes, etc., and is not specifically limited here.

[0065] In some implementations, the initial reference value is the first stable value monitored by the color sensor 30 after power-on, based on the environment surrounding the kitchen appliance 100, or the initial reference value comes from a terminal communicating with the kitchen appliance 100. With this setting, the initial reference value is the real-time detection value output by the color sensor 30 after power-on, allowing the user to turn on the color sensor 30 even in the absence of cooking fumes, enabling the color sensor 30 to adjust the initial reference value for different environments surrounding each kitchen appliance 100; alternatively, the user can conveniently and quickly set the initial reference value directly through a terminal communicating with the kitchen appliance 100.

[0066] In some implementations, S20 includes: determining the fume scene based on the correspondence between smoke concentration data and pre-stored smoke concentration data and fume scenes. There are many methods for determining the correspondence between smoke concentration data and fume scenes; it can be set through simulation, experimentation, etc. The specific correspondence between smoke concentration data and fume scenes can be adjusted according to actual needs, and no specific limitations are imposed here. In this way, the fume scene can be derived from the smoke concentration data, thereby providing a basis for determining the operating parameters of the fan 20.

[0067] In some implementations, S30 includes:

[0068] If the fume extraction scenario is determined to be a smoke-free scenario, the fan should be turned off.

[0069] In some implementations, the controller 10 is used to control the fan 20 to shut down when the fume scene is determined to be a smoke-free scene.

[0070] Thus, in a smoke-free environment, since there is no oil fume, there is no need for kitchen appliances to extract it, and turning off the fan in time can effectively reduce energy consumption and save energy.

[0071] Specifically, when the smoke concentration data indicates that the current cooking fume scenario is smoke-free, the fan 20 will be shut off. Smoke-free scenarios include situations where the stove is not lit, or where the kitchen appliance 100 has run long enough to remove all cooking fumes after the cooking process is complete. In these cases, promptly shutting off the fan 20 helps save energy. Additionally, the operation of the fan 20 generates noise; shutting it off also helps reduce environmental noise.

[0072] In some implementations, S30 further includes:

[0073] If the fume scenario is determined to be a low-fume scenario, control the fan to run at a low speed.

[0074] In some implementations, the controller 10 is used to control the fan 20 to operate at a low speed when the fume scenario is determined to be a low fume scenario.

[0075] Thus, in low-fume scenarios, the fan can meet the usage requirements by operating at a low speed, effectively removing fumes in a timely manner, and saving power consumption compared to operating at a high speed.

[0076] Specifically, in this embodiment, when the current oil fume scenario is determined to be a low-fume scenario based on the smoke concentration data, the fan 20 is controlled to operate at a low speed. Low-fume scenarios include situations such as heating a pot or simmering over low heat. In such cases, operating the fan 20 at a low speed is sufficient to meet the needs of fume extraction.

[0077] In some implementations, S30 further includes:

[0078] If the fume scenario is determined to be a high-fume scenario, control the fan to operate at a high speed.

[0079] In some implementations, the controller 10 is used to control the fan 20 to operate at a high speed when the fume scene is determined to be a high fume scene.

[0080] In this way, in high-fume scenarios, the fan can be adjusted to a high setting to promptly exhaust the fumes and ensure a clean kitchen environment.

[0081] Specifically, in this embodiment, when the current oil fume scenario is determined to be a high-fume scenario based on the smoke concentration data, the motor is controlled to operate at a high speed. High-fume scenarios include frying, stir-frying over high heat, etc. In this case, the fan 20 is adjusted to a high speed to promptly exhaust a large amount of oil fume from the kitchen, ensuring the air quality in the kitchen.

[0082] Please see Figure 5 In some embodiments, the kitchen appliance 100 includes an alarm device 40, and the oil fume scenario also includes an abnormal oil fume scenario. The control method includes:

[0083] If the fume scene is determined to be an abnormal fume scene, the alarm device will be activated.

[0084] In some implementations, the controller 10 is used to control the alarm device 40 to sound an alarm when it is determined that the oil fume scene is abnormal.

[0085] In this way, the alarm device can sound an alarm in a timely manner in abnormal oil fume scenarios, thereby reducing the probability of food burning and fire.

[0086] Specifically, in this embodiment, abnormal oil fume scenarios include situations such as excessive oil fume caused by excessive heating temperature or food catching fire. In such cases, the controller 10 can control the alarm device 40 to sound an alarm when it determines that the current oil fume scenario is an abnormal oil fume scenario, so as to promptly warn the user of the abnormal situation. Alternatively, when the controller 10 determines that the current oil fume scenario is an abnormal oil fume scenario, it can first control the fan 20 to run at a high level to speed up the extraction of oil fumes. If the current oil fume scenario is still an abnormal oil fume scenario after the fan 20 has been extracting for a period of time, the controller 10 can then control the alarm device 40 to sound an alarm, so as to avoid frequent alarms that would result in a poor user experience.

[0087] In some implementations, when the temperature of the cookware exceeds a preset temperature and the smoke concentration data exceeds a preset concentration, the oil fume scenario is determined to be an abnormal oil fume scenario, or

[0088] When the smoke concentration data is greater than the preset concentration, the oil fume scene is determined to be an abnormal oil fume scene.

[0089] Thus, abnormal oil fume scenarios can be identified by using smoke concentration data, or by using cookware temperature and oil fume concentration data, providing a basis for changes in fan power.

[0090] Specifically, in this embodiment, the cookware is a cooking utensil that generates oil fumes and is located near the kitchen appliance 100. There are many methods for obtaining the temperature of the cookware, such as setting up an infrared temperature detection device whose detection range includes the cookware; or setting up a thermometer that comes into contact with the cookware to measure its temperature. These methods will not be listed here. The specific data for the preset temperature and preset concentration can be set as needed and are not specifically limited here.

[0091] There are many types of alarm devices 40, such as buzzers, LED lights, etc. Of course, the kitchen appliance 100 also includes a communication unit. The controller 10 connects the communication unit and the alarm device 40. The kitchen appliance 100 can also wirelessly send alarm information to the terminal that communicates with the kitchen appliance 100.

[0092] An embodiment of the present invention provides a non-volatile computer-readable storage medium containing computer-executable instructions, which, when executed by one or more processors, causes the processors to perform the control method of any of the above embodiments.

[0093] When the instructions in the storage medium of the present invention are executed, the kitchen appliance 100 determines the current oil fume scene based on the smoke concentration data detected by the color sensor 30, and then determines the operating parameters of the fan 20 according to the oil fume scene. For different oil fume scenes, the fan 20 operates with different parameters, which effectively improves the oil fume extraction effect.

[0094] This invention also proposes a kitchen appliance 100. Specifically, the kitchen appliance 100 includes, but is not limited to, appliances with fume extraction functions such as range hoods and integrated cooktops. In the illustrated embodiment, the kitchen appliance 100 is described using a range hood as an example. This kitchen appliance 100 can be a top-exhaust kitchen appliance, a bottom-exhaust kitchen appliance, or a side-exhaust kitchen appliance; no specific limitation is made here. Please refer to... Figure 2 The following is a detailed description using kitchen appliance 100 as an example of an upward-exhausting range hood.

[0095] The kitchen appliance 100 of this invention includes a baffle plate 50, a housing 60, a fan 20, a controller 10, and a color sensor 30. The housing 60 is mounted on the baffle plate 50, which includes a touch button. When the touch button is triggered, the kitchen appliance 100 is turned on, allowing oil fume particles to enter the housing 60 from the baffle plate 50. The fan 20 is located inside the housing 60 and provides power for the exhaust of oil fume particles. The controller 10 and the color sensor 30 are mounted on the baffle plate 50 and / or the housing 60. The controller 10 is connected to the fan 20 and the color sensor 30 to acquire smoke concentration data output by the color sensor 30, determine the oil fume scenario based on the smoke concentration data, and determine the operating parameters of the fan 20 based on the oil fume scenario.

[0096] In some implementations, please refer to Figure 6 The color sensor 30 includes a housing 31, a color sensing component 32, and a convex lens 33. The housing 31 has a receiving cavity 34, in which the color sensing component 32 is installed. The housing 31 also has a display opening 311 for the color sensing component 32 to be exposed. The convex lens 33 is located on the color sensing component 32 and covers the display opening 311.

[0097] Thus, the color sensor 30 includes a convex lens 33. Due to the refraction of light by the convex lens 33, the detection range of the color sensing component 32 located below the convex lens 33 is effectively increased, thereby improving the sensitivity of the color sensing component 32.

[0098] Specifically, the color sensing component 32 is a component that realizes the color detection function. It may include a color sensing device, or a light source such as an LED lamp or a halogen lamp. It only needs to be able to realize the color detection function, and there are no specific limitations here.

[0099] There are many types of structures for the housing 31. It can be a one-piece molded structure, in which case the color sensing component 32 and the convex lens 33 can be installed through the exposed opening 311. Alternatively, it can be a split structure, in which case the housing 31 consists of several parts, and the parts are assembled to form the housing 31.

[0100] In some embodiments, the housing 31 includes an upper cover 312 and a lower cover 313, which together form a receiving cavity 34. The upper cover 312 has an exposure opening 311 for exposing the color sensing component 32, and the upper cover 312 and the lower cover 313 are detachably connected. This facilitates the disassembly of the color sensor 30, enabling maintenance and replacement of the color sensing component 32, and avoiding inaccurate detection results due to damage or aging of the color sensing component 32.

[0101] Furthermore, the upper cover 312 includes a cover body 3121, an abutment portion 3122, and a retaining ring 3123. The cover body 3121 has an exposure opening 311 for the color sensing component 32 to be exposed. The abutment portion 3122 passes through the exposure opening 311 and cooperates with the cover body 3121. The abutment portion 3122 is arranged in a ring shape. The retaining ring 3123 is located inside the abutment portion 3122, and the edge of the convex lens 33 is clamped between the abutment portion 3122 and the retaining ring 3123. The abutment portion 3122 and the retaining ring 3123 cooperate to clamp the convex lens 33. Compared with fixed connection methods such as bonding and welding, this design allows users to easily and quickly disassemble and clean the convex lens 33, thereby reducing the probability of inaccurate detection results of the color sensor 30 due to dirt or damage to the convex lens 33.

[0102] In some embodiments, the top cover 312 includes a body (not shown) and a connecting ring (not shown). The body has an exposure opening 311 for the color sensing component 32 to be exposed. The body also has an annular protrusion extending in a direction away from the color sensing component 32. The outer wall of the annular protrusion has a first thread, and the inner wall of the connecting ring has a second thread that mates with the first thread. The connecting ring and the body together clamp the edge of the convex lens 33. With this configuration, the user can remove the convex lens 33 for replacement and cleaning by rotating the connecting ring, reducing the probability of inaccurate detection results of the color sensor 30 due to dirt or damage to the convex lens 33.

[0103] Furthermore, the deflector 50 has a through hole (not marked), through which an annular protrusion passes. The portion of the body excluding the annular protrusion is located inside the deflector 50. A connecting ring connects to the annular protrusion located outside the deflector 50, and the annular protrusion abuts against the deflector 50. This arrangement places the portion of the body excluding the annular protrusion inside the deflector 50, protecting this portion and reducing the probability of it coming into contact with dirt. Additionally, the annular protrusion with the convex lens 33 and the connecting ring are located outside the deflector 50, allowing the user to easily separate the connecting ring from the annular protrusion and remove the convex lens 33, thus facilitating cleaning or replacement of the convex lens 33.
