Detailed Implementation

[0033] Embodiments of the present invention are described in detail below. These embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] 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.

[0035] Please see Figure 1 as well as Figure 2 The control method of this invention is used for a kitchen appliance 100. The kitchen appliance 100 includes a light 10, a fan 20, and a color sensor 30. The control method includes the following steps:

[0036] S10 determines the kitchen usage scenario based on the output data of the color sensor;

[0037] S20, determine the operating parameters of kitchen appliances based on the kitchen usage scenario;

[0038] S30 controls the operation of lighting and fans based on the operating parameters of kitchen appliances.

[0039] Please see Figure 3 The kitchen appliance 100 of this invention includes a controller 40, a lighting lamp 10, a fan 20, and a color sensor 30.

[0040] The controller 40 is connected to the lighting lamp 10, the fan 20, and the color sensor 30. The controller 40 is used to determine the kitchen usage scenario based on the output data of the color sensor 30, determine the operating parameters of the kitchen appliance 100 based on the kitchen usage scenario, and control the operation of the lighting lamp 10 and the fan 20 based on the operating parameters of the kitchen appliance 100.

[0041] In other words, the control method of the present invention can be implemented by the kitchen appliance 100 of the present invention.

[0042] Specifically, the control method of the present invention can be implemented by the controller 40, that is, the controller 40 is used to determine the kitchen usage scenario based on the output data of the color sensor 30, determine the operating parameters of the kitchen appliance 100 based on the kitchen usage scenario, and control the operation of the lighting 10 and the fan 20 based on the operating parameters of the kitchen appliance 100.

[0043] The kitchen appliance 100 and control method of the present invention determine the kitchen usage scenario based on the output data of the color sensor 30, thereby determining the operating parameters of the kitchen appliance 100 based on the kitchen usage scenario, and then controlling the kitchen appliance 100 based on the operating parameters of the kitchen appliance 100. For different kitchen usage scenarios, the lighting 10 and the fan 20 can adopt different operating parameters, thereby improving the user experience.

[0044] Specifically, in step S10, the number of color sensors 30 can vary greatly, including 1, 2, 3, 4, 5 or other numbers, and no specific limit is imposed here.

[0045] It is worth noting that when there are multiple color sensors 30, their detection ranges can partially or completely overlap. The average output data from the overlapping detection ranges of the color sensors 30 can be used as the basis for determining the kitchen usage scenario, or the output data from the overlapping detection ranges can be weighted and used as the basis for determining the kitchen usage scenario. Alternatively, the detection ranges of the color sensors 30 can not overlap. For example, some color sensors 30 may cover the area near the stove and cookware to detect if a user is near them, while others may cover the location of room lights to detect whether the lights are on or off. The specific number of color sensors 30 and the specific method for determining the current output data can be adjusted based on production costs, detection accuracy, etc., and are not specifically limited here.

[0046] Specifically, based on the output data of the color sensor 30, common kitchen usage scenarios in actual operation are divided into the following categories:

[0047] The user approach scenario, the user usage scenario, and the user departure scenario.

[0048] In some implementations, the "user approaching scenario" corresponds to the user entering the kitchen, such as starting to use cooking utensils like stoves and pots, or starting to wash and chop vegetables. The "user using scenario" corresponds to the user using cooking utensils like stoves and pots, or washing and chopping vegetables, or actively using the kitchen. The "user leaving scenario" corresponds to the user leaving the kitchen after using cooking utensils like stoves and pots, or after chopping and washing vegetables. This categorization of user usage scenarios provides a basis for determining the operating parameters of the kitchen appliance 100.

[0049] In steps S20 and S30, the operating parameters of the kitchen appliance 100 may include the operating parameters of the lighting 10, the operating parameters of the fan 20, etc.

[0050] The operating parameters of the lighting lamp 10 may include "on" and "off". When the operating parameter of the lighting lamp 10 is "off", the lighting lamp 10 can be controlled not to work according to the off operating parameter; when the operating parameter of the lighting lamp 10 is "on", the lighting lamp 10 can be controlled to work according to the on operating parameter.

[0051] Furthermore, the operating parameters of the lighting lamp 10 can include low brightness on, high brightness on, etc. Based on different operating parameters, the lighting lamp 10 can be controlled to turn on at different power levels, thereby producing different brightness effects. By controlling the lighting lamp 10 to provide light sources of varying brightness according to its different operating parameters, it is understandable that the lighting effect of the lighting lamp 10 differs under different brightness levels, allowing the lighting lamp 10 to provide appropriate lighting effects in a timely manner for different kitchen usage scenarios.

[0052] It is worth noting that the operating parameters for low-brightness and high-brightness operation of the lighting lamp 10 are not fixed and can be adjusted according to user needs and actual usage. No specific limitations are made here. Of course, the operating parameters for the lighting lamp 10 can also include medium-brightness, medium-low brightness, and other operating parameters, or multiple refined high-brightness operating parameters under the high-brightness operating parameters. These can be added or removed as needed, and no specific restrictions are made here.

[0053] The operating parameters of the fan 20 can include "on" and "off". The operating parameters of the fan 20 can include low-power operation and high-power operation. When the operating parameter of the fan 20 is "off", the fan 20 can be controlled not to operate based on this parameter. When the operating parameter of the fan 20 is "on", the fan 20 can be controlled to operate based on this parameter. Furthermore, the fan 20 can be controlled to operate at different power levels based on different operating parameters. By controlling the fan 20 to operate at different power levels according to different operating parameters, different suction forces can be obtained, thus enabling the fan 20 to provide a better smoke extraction effect in a timely manner when facing different kitchen usage environments.

[0054] It is worth noting that the operating parameters 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. No specific limitations are made here. Of course, the operating parameters for the fan 20 can also include operating parameters for medium-power and variable-speed power operation, or multiple detailed low-power operating parameters under the low-power operating parameters. These can be added or removed as needed, without specific restrictions.

[0055] In some implementations, please refer to Figure 4 S10 includes:

[0056] 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;

[0057] S12: Determine the kitchen usage scenario based on the correspondence between the real-time monitoring values ​​and color change values ​​and the pre-stored real-time monitoring values, color change values ​​and kitchen usage scenarios.

[0058] In some implementations, the controller 40 is used to output a color change value based on the difference between the real-time detection value output by the color sensor and the initial reference value, and to determine the kitchen usage scenario based on the real-time monitoring value and the color change value and the pre-stored correspondence between the real-time monitoring value and the color change value and the kitchen usage scenario.

[0059] 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. The color change value is obtained by comparing the difference between the initial reference value and the real-time detection value. The color change is caused by the turning the kitchen lights on and off, and by people approaching or moving away. Therefore, the color change value can be used to deduce whether the kitchen lights are on or off, and whether people are approaching or moving away from the kitchen appliance 100. The real-time detection values ​​differ depending on whether a person is near the kitchen appliance 100, whether the person is not near the kitchen appliance 100, and whether the kitchen lights are on or off. Therefore, the real-time monitoring value can be used to determine whether a person is near the kitchen appliance 100 and whether the kitchen lights are on or off.

[0060] There are many ways to correlate color change values ​​and real-time detection values ​​with kitchen usage scenarios. For example, you can first determine whether the kitchen lights are on based on the color change values ​​when the kitchen lights are on and off. When the kitchen lights are on, you can determine whether a person is near the kitchen appliance 100 based on the color change values ​​generated when a person approaches, thus determining whether the current kitchen usage scenario is a user-approach scenario. Alternatively, you can determine whether the current kitchen usage scenario is a user-approach scenario based on the difference between the real-time detection values ​​when a person is near the kitchen appliance 100 and when a person is not near the kitchen appliance 100.

[0061] It is worth noting that when determining the kitchen usage scenario, the judgment can be made based on multiple real-time detection values ​​and multiple color change values ​​output by the color sensor 30 within multiple adjacent detection cycles, thereby making the determination of the kitchen usage scenario more accurate. This detection cycle can be 50 milliseconds, 1 second, 1 minute, 5 minutes, etc., and no specific limitation is made here.

[0062] Specifically, there are many ways to derive the correspondence between color change values ​​and real-time detection values. These can be obtained through simulation, actual measurement, and other methods, which will not be elaborated here.

[0063] 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 users to turn on the color sensor 30 at home, thus enabling the color sensor 30 to adapt to different kitchen environments for different users by setting the initial reference value; alternatively, users can conveniently and quickly set the initial reference value directly through a terminal communicating with the kitchen appliance 100.

[0064] In some implementations, S20 includes: determining that the operating parameters of the kitchen appliance's lighting are turned on when the kitchen usage scenario is determined to be a user proximity scenario.

[0065] In some implementations, the controller 40 is used to determine that the operating parameters of the kitchen appliance 100's lighting 10 are turned on when the kitchen usage scenario is determined to be a user proximity scenario.

[0066] In this way, when the user approaches the scene, the operating parameters of the kitchen appliance 100's lighting 10 are determined to be "on", providing a basis for controlling the operation of the lighting 10, thereby achieving the effect of automatically turning on the lighting 10 when the user needs to use the kitchen.

[0067] Specifically, when the kitchen usage scenario is determined to be a user approach scenario, the operating parameters of the lighting 10 are set to "on". User approach scenarios include situations where the user starts washing vegetables, the user starts cooking, etc., where the user is near the kitchen appliance 100. In this case, the operating parameters of the lighting 10 are confirmed to be "on", and the operation of the lighting 10 is controlled according to the operating parameters to provide timely lighting for the user and improve the user experience.

[0068] When the kitchen usage scenario is determined to be a user proximity scenario, the operating parameters of the fan 20 can also be determined as low power operation, medium power operation, etc. The operating parameters of other components of the kitchen appliance 100, such as gas sensors and temperature sensors, can also be determined. These can be set by the user through a terminal that communicates with the kitchen appliance 100, or by the factory based on simulation, testing, etc., which will not be listed here.

[0069] In some implementations, S20 further includes:

[0070] Given that the kitchen usage scenario is determined to be the user usage scenario, the operating parameters of the kitchen appliance fan are determined to be the working parameters.

[0071] In some implementations, when the controller 40 determines that the kitchen usage scenario is the user's usage scenario, it determines that the operating parameters of the fan 20 of the kitchen appliance 100 are working.

[0072] In this way, in the user's usage scenario, the operating parameters of the fan 20 are determined to provide a basis for controlling the operation of the fan 20, thereby timely exhausting oil fumes and ensuring a good air environment in the kitchen.

[0073] Specifically, in this embodiment, when the kitchen usage scenario is determined to be a user usage scenario, the operating parameters of the fan 20 are determined to be operational, providing a basis for controlling the operation of the fan 20. User usage scenarios include situations where users use pots, stoves, etc. to cook, cut vegetables, and prepare for cooking. In such cases, oil fumes are usually generated or about to be generated. Timely determination of the operating parameters of the fan 20 is beneficial for timely removal of oil fumes.

[0074] Of course, the operating parameters of the fan 20 can be refined into low-power operation, medium-power operation, etc., which can be set through the terminal communicating with the kitchen appliance 100, or by the manufacturer through simulation, experiment and other data. The settings are based on specific usage habits and needs, and will not be listed here.

[0075] In some implementations, S20 further includes:

[0076] If the kitchen usage scenario is determined to be a scenario where the user leaves, then the operating parameters of the kitchen appliance lighting should be set to off.

[0077] In some implementations, the controller 40 is used to determine the operating parameters of the kitchen appliance 100 in the case of a user leaving the kitchen, based on the kitchen usage scenario.

[0078] In this way, when the user leaves the scene, the operating parameters of the kitchen appliance 100's lighting 10 are promptly determined to be off, providing a basis for controlling the lighting 10 to turn off. This achieves the effect of timely turning off the lights and reducing energy consumption.

[0079] When the kitchen usage scenario is determined to be a user-left scenario, the operating parameters of the fan of kitchen appliance 100 can also be determined as on or off. The operating parameters of other components of kitchen appliance 100, such as gas sensors and temperature sensors, can also be determined. These parameters can be set by the user through a terminal that communicates with kitchen appliance 100, or by the factory based on simulation, testing, etc. No specific restrictions are imposed here.

[0080] The present invention also provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the control method of any of the above embodiments.

[0081] For example, when the program is executed by the processor, the following steps are implemented for control methods:

[0082] S10: Determine the kitchen usage scenario based on the output data of the color sensor;

[0083] S20: Determine the operating parameters of kitchen appliances based on the kitchen usage scenario;

[0084] S30: Controls the operation of lights and fans based on the operating parameters of kitchen appliances.

[0085] The computer-readable storage medium of this invention can determine the kitchen usage scenario based on the output data of the color sensor 30, determine the operating parameters of the kitchen appliance 100 based on the kitchen usage scenario, and control the operation of the lighting 10 and the fan 20 based on the operating parameters of the kitchen appliance 100. This enables timely adjustment of the operating parameters of the kitchen appliance 100 in different user usage scenarios, thereby timely controlling the operation of the lighting 10 and the fan 20, improving the intelligence level of the kitchen appliance 100 and enhancing the user experience.

[0086] The computer-readable storage medium can be located in the kitchen appliance 100 or in a cloud server. The kitchen appliance 100 can communicate with the cloud server to obtain the corresponding program.

[0087] It is understood that a computer program includes computer program code. Computer program code can be in the form of source code, object code, executable files, or some intermediate form. Computer-readable storage media can include: any entity or device capable of carrying computer program code, recording media, USB flash drives, external hard drives, magnetic disks, optical disks, computer memory, read-only memory (ROM), random access memory (RAM), and software distribution media, etc.

[0088] The controller 40 of the kitchen appliance 100 is a microcontroller chip that integrates a processor, memory, communication module, etc. The processor can refer to the processor contained within the controller 40. The processor can be a Central Processing Unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0089] 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.

[0090] The kitchen appliance 100 of this invention includes a deflector plate 50, a housing 60, a lighting lamp 10, a fan 20, a controller 40, and a color sensor 30.

[0091] The cabinet 60 is mounted on the baffle 50, which includes a touch button. When the touch button is triggered, the kitchen appliance 100 is turned on, and oil fume particles can enter the cabinet 60 through the baffle 50. A light 10 is located inside the cabinet 60 and is used to provide illumination for the user.

[0092] The fan 20 is located inside the housing 60 and is used to provide power for the exhaust of oil fume particles. The controller 40 and the color sensor 30 are located on the baffle 50 and / or the housing 60. The lighting 10, the controller 40, the fan 20, and the color sensor 30 are connected to determine the kitchen usage scenario based on the output data of the color sensor 30, determine the operating parameters of the kitchen appliance 100 based on the kitchen usage scenario, and control the operation of the lighting 10 and the fan 20 based on the operating parameters of the kitchen appliance 100.

[0093] In some implementations, please refer to Figure 5 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.
