The entire contents of the above Chinese patent applications are incorporated into this application by reference. Technical Field

[0002] The present application relates to the technical field of kitchen appliances, and in particular to a control method and system for household appliances, a computer-readable storage medium, and a computer device. Background Art

[0003] Range hoods, as a kitchen appliance, are primarily used to promptly remove oil, heat, and other media carried by ovens and pots during cooking, thereby ensuring air quality. Cookers, as other kitchen appliances, primarily provide heat to pots and other appliances placed on the burner to cook the ingredients within. For example, a stove may include a proportional valve. By adjusting the valve's on / off state and specific opening, the stove can have different power levels, enabling optimal cooking.

[0004] During cooking, there may be a need to adjust the stove's on / off status and heat level, as well as the range hood's fan speed. To better meet user needs, there may also be a need to adjust both simultaneously. For example, current adjustment methods are typically manual. Automatic adjustment methods typically employ multiple, diverse detection components. Therefore, there is still room for improvement in the adjustment mechanisms of household appliances. Summary of the Invention

[0005] The present application aims to at least partially solve the above technical problems and / or solve at least part of the above technical problems, specifically, how to optimize the adjustment mechanism of household appliances as much as possible.

[0006] In a first aspect, the present application provides a control method for a household appliance, the control method comprising: receiving operating parameters of a range hood and / or a stove; adjusting the operating parameters of the range hood and / or the stove based on the operating parameters of the stove and image data of a target area collected by an image acquisition component provided in the range hood; wherein the target area is an area corresponding to the stove.

[0007] Through such a structure, it is possible to adjust the operating parameters of the range hood / stove based on the image data collected by the image acquisition component installed on the range hood, which is expected to improve the performance of home appliances related to current cooking in areas such as cooking continuity, cooking quality, and user experience.

[0008] It should be noted that the phrase "the target area corresponds to the stove" should be understood as follows: the image data captured should be of the area associated with the current cooking process. The ingredients being cooked are placed in the pot on the stovetop. Therefore, the image data captured of the area corresponding to the stovetop accurately reflects the current cooking state. For example, as long as the captured image data accurately reflects the current cooking state, the target area may be slightly larger than, equal to, or slightly smaller than the stovetop area.

[0009] It is understandable that the image data of the target area can reflect the current cooking status (such as the amount of smoke, the amount / maturity of the ingredients in the pot (such as reflected by attributes such as color), the amount / boiling state of water in the pot, etc.) through different parameters to reflect the cooking status of the pot placed on the burner of the stove, and technical personnel in this field can determine the mapping relationship between the operating parameters of the range hood / stove and the image data according to actual needs.

[0010] For example, in the case of waterless cooking methods such as frying, grilling, and deep-frying, the range hood is used as the primary target device to adjust its operating parameters, while in the case of water-based cooking methods such as steaming, boiling, and stewing, the stove is used as the primary target device to adjust its operating parameters. Of course, the other device can also be adjusted. On this basis, those skilled in the art can determine the mapping relationship between the operating parameters of the range hood / stove and the image data for different cooking methods according to actual needs. In addition, it is understandable that the "primary target device" should be understood as the most important device that can improve cooking performance. Obviously, the operating parameters of other devices can also be adjusted, such as through the combination of range hood and stove to further improve cooking performance.

[0011] It is understood that those skilled in the art may determine the structural form of the range hood / image acquisition component, the arrangement of the image acquisition component on the range hood, etc. based on actual needs. For example, the image acquisition component may be disposed at any reasonable location outside and / or inside the range hood chamber (e.g., the housing, the front panel glass, etc.).

[0012] For the above-mentioned control method, in one possible implementation, the "adjusting the operating parameters of the range hood and / or the stove based on the operating parameters of the range hood and / or the stove and the image data of the target area collected by the image acquisition component" includes: determining the current cooking state of the pot based on the image data collected by the image acquisition component; and adjusting the operating parameters of the range hood and / or the stove based on the current cooking state.

[0013] For the above-mentioned control method, in one possible implementation, in the step of "adjusting the operating parameters of the range hood and / or the stove based on the operating parameters of the range hood and / or the stove and the image data of the target area collected by the image acquisition component", the operating parameter of the stove is the fire power of the stove.

[0014] Through such a structure, it is possible to adjust the firepower of the stove so that it can be more suitable for the current cooking. In this way, the cooking efficiency can be improved as much as possible while avoiding extreme problems such as overflowing and dry burning.

[0015] It is understood that those skilled in the art can determine the mapping relationship between image data and the stove's heat power, the specific method for adjusting the heat power, etc. according to actual needs. For example, the heat power can be adjusted continuously or periodically, and the amplitude of a single adjustment can also be flexibly selected according to actual conditions.

[0016] With respect to the above-mentioned control method, in one possible embodiment, the cooker includes a gas circuit assembly, the gas circuit assembly including a proportional valve assembly, the proportional valve assembly including: a valve body; an air inlet valve disposed at an air inlet valve port of the valve body; and at least one air outlet valve disposed at at least one air outlet valve port of the valve body; wherein the valve body is provided with a connecting structure in a passage corresponding to the air inlet valve port and the at least one air outlet valve port; the step of "adjusting the operating parameters of the range hood and / or the cooker based on the operating parameters of the range hood and / or the cooker and the image data of the target area captured by the image acquisition component" includes: in the step of "determining a current cooking state of the cookware based on the image data captured by the image acquisition component", the current cooking state is an overflow state of the cookware; and the step of "adjusting the operating parameters of the range hood and / or the cooker based on the current cooking state" includes: opening the air inlet valve and closing the air outlet valve based on the overflow state of the cookware, so that the gas reaches the burner of the cooker through the connecting structure.

[0017] This configuration effectively prevents cooking interruptions caused by the stove being turned off by operating the stove at the minimum power setting. Specifically, even when the gas outlet valve is closed, the minimum power setting can still provide heat, thereby preventing the stove's burner from flameout. This effectively prevents or eliminates overflowing pots by operating the minimum power setting, thereby ensuring the sustainability of the cooking process. Furthermore, by preventing cooking interruptions caused by the stove being turned off, the continuity of the entire cooking process is ensured.

[0018] It is understandable that those skilled in the art can determine the form of the cooking state and its corresponding relationship with the minimum fire power level according to actual needs. For example, the overflowing state can be determined by image data alone or by combining image data with other data.

[0019] Furthermore, it is understood that those skilled in the art can determine the specific method for determining the overflow state and the types of overflow states according to actual needs. For example, the overflow state may include two states: about to overflow and already overflowed. Both the about to overflow state and the already overflowed state may further include multiple gears. Taking the already overflowed state as an example, multiple states may include, but are not limited to, slightly stable, slightly rising, rapidly overflowing, and severely overflowing.

[0020] In one possible embodiment, the at least one outlet valve includes a first outlet valve and a second outlet valve disposed between the inlet valve and the first outlet valve. The connecting structure is disposed in the passage between the inlet valve and the second outlet valve. This configuration provides a clear location for the connecting structure on the proportional valve assembly.

[0021] In one possible embodiment, the valve body includes a first passage section arranged along the axis of the intake valve; and a second passage section at an angle to the first passage section. The intake valve port can sequentially communicate with the outlet valve port via the first and second passage sections. The communication structure is provided in the second passage section. This configuration allows the air supply quality corresponding to the communication structure to be similar to that of the second outlet valve port.

[0022] In one possible embodiment, the first passage section is substantially perpendicular to the second passage section; and / or the axis of the communication structure is substantially parallel to the axis of the outlet valve. This configuration provides a specific arrangement of the communication structure on the second passage.

[0023] In one possible embodiment, the connecting structure is disposed on the valve body near the outlet valve port when viewed along the air supply direction of the air path assembly. This configuration can further ensure that the air supply quality corresponding to the connecting structure is close to that of the second outlet valve port.

[0024] In a possible embodiment, the communication structure is provided at a position of the valve body that is not mid-section. With such a configuration, it is possible to seek to better ensure the quality of gas supply based on the communication structure.

[0025] In one possible embodiment, the cross-sectional size of the connecting structure is smaller than the cross-sectional size of the outlet valve port; and / or when viewed along the air supply direction of the air path assembly, the cross-sectional size of the downstream side of the connecting structure is greater than or equal to the cross-sectional size of the upstream side.

[0026] In one possible embodiment, the connecting structure includes a first connecting section and a second connecting section, wherein the first connecting section is located on the upstream side of the second connecting section along the air supply direction of the air path assembly, and wherein the cross-sectional size of the second connecting section is larger than the cross-sectional size of the first connecting section.

[0027] In one possible embodiment, the communication structure includes one or more components; and / or the communication structure is provided in the passage in a switchable or normally open manner; and / or the same communication structure can communicate with the passages of the inlet valve port and one or more outlet valve ports. This configuration provides a possible form in which the communication structure constitutes a proportional valve assembly.

[0028] For the above-mentioned control method, in a possible implementation manner, in the step of "adjusting the operating parameters of the range hood and / or the stove based on the operating parameters of the range hood and / or the stove and the image data of the target area acquired by the image acquisition component", the operating parameters of the range hood include: the range hood includes a fan, and the operating parameters of the range hood include the operating parameters of the fan; and / or the range hood includes an atmosphere light, and the operating parameters of the range hood include the operating parameters of the atmosphere light.

[0029] Through such a configuration, possible forms of operating parameters of the range hood are given.

[0030] It is understandable that those skilled in the art can determine the structural form of the fan / atmosphere light and its arrangement on the range hood according to actual needs. For example, the atmosphere light can be arranged on the range hood in an embedded or non-embedded manner.

[0031] In addition, it is understandable that those skilled in the art can determine the specific form of the operating parameters of the fan / atmosphere light, the mapping relationship between the image data and the operating parameters of the range hood, etc. according to actual needs. For example, the operating parameters of the fan may include speed, power, operating time, etc., and the operating parameters of the atmosphere light may include the operating style of the atmosphere light (such as running, flashing, always on, etc.), power, operating time, etc.

[0032] For the above-mentioned control method, in a possible implementation manner, in the step of “adjusting the operating parameters of the range hood and / or the stove based on the operating parameters of the range hood and / or the stove and the image data of the target area collected by the image acquisition component”, the step of “adjusting the operating parameters of the range hood based on the operating parameters of the range hood and / or the stove and the image data of the target area collected by the image acquisition component” includes: when it is determined that the pot has been removed from the stove based on the image data of the target area collected by the image acquisition component, reducing the speed of the fan; and / or when it is determined that the pot is overflowing based on the image data of the target area collected by the image acquisition component, increasing the speed of the fan; and / or when it is determined that the pot is dry-burning based on the image data of the target area collected by the image acquisition component; adjusting the operating parameters of the atmosphere light when the operating parameters of the stove are adjusted, the operating parameters of the fan are adjusted, the pot is overflowing, the pot is overflowing, and / or the pot is removed from the stove.

[0033] Through such a structure, a possible adjustment method for the operating parameters of the range hood is provided.

[0034] For example, for a fan, those skilled in the art can determine the specific method for increasing or decreasing the speed based on actual needs, such as determining it solely based on image data or in combination with the operating parameters of the stove. In other words, those skilled in the art can determine the mapping relationship between speed adjustment and image data based on actual needs, such as enabling continuous adjustment or step-by-step adjustment.

[0035] Regarding the above-mentioned control method, in a possible implementation, it is characterized in that the range hood includes: a range hood main body, which is formed with a chamber; and a flap assembly, which is movably arranged on the range hood main body and can cover the chamber; wherein, the image acquisition component is arranged at a position of the range hood main body close to the flap assembly; the control method includes: starting the image acquisition component when the flap assembly is in the process of opening or is already opened.

[0036] With this configuration, when the range hood is in operation, less air flows through the image acquisition component area, thus ensuring both temperature and cleanliness. For example, the device can be installed outside or inside the chamber, or at any outer edge near the flap. For example, when the flap assembly is closing or fully closed, the image acquisition component is placed in a dormant state or shut down.

[0037] In one possible embodiment, the flap assembly includes a pivoting side and a free side, wherein the image acquisition component is disposed proximate to the pivoting side of the flap assembly. This configuration allows the image acquisition component to capture image data unobstructed when the range hood is in operation, thereby ensuring image data quality. Typically, the flap assembly is pivotally connected to the range hood body at a position proximate to the pivoting side.

[0038] In a possible embodiment, the image acquisition component is disposed in the chamber. With such a configuration, the cleanliness of the image acquisition component can be ensured when the range hood is in a non-operating state.

[0039] In a possible embodiment, the flap assembly is arranged at a position near the bottom of the range hood body in an openable and closable manner, so that: when the flap assembly covers the chamber at the bottom of the range hood body, the image acquisition component is accommodated in the chamber.

[0040] In a second aspect, the present application provides a control method for household appliances, the control method comprising: receiving image data of a target area captured by the image acquisition component provided on the range hood; adjusting the operating parameters of the range hood and / or the stove based on the image data and the operating parameters of the range hood and / or the stove; wherein the target area is an area corresponding to the stove.

[0041] It can be understood that the control method has all the technical effects described in any of the aforementioned home appliance control methods, which will not be repeated here.

[0042] In a third aspect, the present application provides a control method for household appliances, the control method comprising: receiving operating parameters of a range hood and / or a stove; and receiving image data of a target area acquired by an image acquisition component provided in the range hood; adjusting the operating parameters of the range hood and / or the stove according to the operating parameters of the range hood and / or the stove and the image data; wherein the target area is an area corresponding to the stove.

[0043] It can be understood that the control method has all the technical effects described in any of the aforementioned home appliance control methods, which will not be repeated here.

[0044] In a preferred embodiment of the present application, by arranging an image acquisition component on the range hood, it is possible to adjust the operating parameters of the range hood / stove (such as the operating parameters of the range hood may include the operating parameters of the fan and / or atmosphere light, and the operating parameters of the stove may include parameters related to firepower) based on the image data collected. On the premise of expanding the atmosphere light, it is expected to optimize the performance of household appliances through the joint adjustment of the range hood and stove.

[0045] In a fourth aspect, the present application provides a control system for a household appliance, the control system comprising a stove main control board, an image acquisition component, and a range hood main control board, the image acquisition component comprising an image acquisition module and an image acquisition module control board, wherein the stove main control board is in a bidirectional signal connection with the image acquisition component, the image acquisition component is in a bidirectional signal connection with the range hood main control board, and the image acquisition module is in a bidirectional signal connection with the image acquisition module control board, so as to:

[0046] Scenario 1: The range hood main control board receives the operating parameters of the range hood transmitted by the range hood main control board via the image acquisition module control board; the range hood main control board adjusts the operating parameters of the range hood and / or the range hood and the image data of the target area captured by the image acquisition component provided in the range hood, and / or transmits an instruction to adjust the operating parameters of the range hood to the range hood main control board via the image acquisition module control board; or

[0047] Scenario 2: The stove main control board receives image data of the target area captured by the image acquisition component and transmitted by the image acquisition module control board; the stove main control board adjusts the operating parameters of the stove based on the image data and the operating parameters of the range hood and / or the stove, and / or transmits an instruction for adjusting the operating parameters of the range hood to the range hood main control board via the image acquisition module control board; or

[0048] Scenario three: The cloud receives the operating parameters of the range hood and / or stove; wherein, the range hood main control board uploads the operating parameters of the range hood to the cloud via the image acquisition module control board, and the stove main control board uploads the operating parameters of the stove to the cloud via the image acquisition module control board; and receives image data of the target area acquired by the image acquisition component provided in the range hood; the cloud adjusts the operating parameters of the range hood and / or the stove according to the operating parameters of the range hood and / or the stove and the image data; wherein, the cloud sends the instruction for adjusting the operating parameters of the range hood to the range hood main control board via the image acquisition module control board, and the cloud sends the instruction for adjusting the operating parameters of the stove to the stove main control board via the image acquisition module control board; wherein, the target area is the area corresponding to the stove.

[0049] Combining the three scenarios above, it can be seen that the above-mentioned home appliance control method can be implemented through a local terminal such as a stove / range hood or the cloud. Specifically, if implemented through a stove main control board installed on the stove, the image data should be obtained by the image acquisition module control board transmitting the image data collected by the image acquisition component to the stove main control board, and the operating parameters of the range hood should be transmitted to the range hood main control board via the image acquisition module control board. If implemented through the range hood main control board installed on the range hood, the image data should be obtained by the image acquisition module control board transmitting the image data collected by the image acquisition component to the stove main control board, and the operating parameters of the range hood should be transmitted to the range hood main control board via the image acquisition module control board. If implemented through the cloud, the image data should be obtained by the image acquisition module control board uploading the image data collected by the image acquisition component to the cloud, and the operating parameters of the range hood / stove should be transmitted to the range hood / stove main control board via the image acquisition module control board.

DETAILED DESCRIPTION

[0063] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0064] For example, for the range hood among household appliances, although the present embodiment is described in conjunction with a product form in which the flap assembly is arranged below the range hood body, it is obvious that those skilled in the art can determine the relative position of the flap assembly and the range hood body, the specific method of opening and closing the flap assembly, etc. according to actual needs. For example, the flap assembly can be arranged at any reasonable position, such as the front side of the range hood body, part of the bottom, etc.

[0065] For example, for a stove in a household appliance, the burners included in the stove can be flexibly adjusted according to actual needs. In addition, the proportional valve assembly described in this application can be configured for some burners, or only for some burners.

[0066] In addition, in addition to range hoods and stoves, household appliances may also include other related equipment such as ovens. On this basis, multiple terminals can be controlled. For example, the oven is installed in a cabinet below the stove in an embedded manner. If the oven adopts a gas upward exhaust method (such as an independent exhaust system, an integrated exhaust system such as an exhaust port that can be connected to the oven is provided on the stove surface of the stove), then the smoke quality perceived by the range hood (such as temperature, degree of dirtiness, etc.) and the image data collected by the image acquisition component may be related to the oven. Therefore, the operating parameters of the oven can be adjusted.

[0067] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be understood as limiting this application. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0068] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "set," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0069] In addition, to better illustrate the present application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art will appreciate that the present application can still be implemented without certain specific details. In some instances, the detailed structures and principles of range hoods and stoves, which are well known to those skilled in the art, are not described in detail in order to highlight the main purpose of the present application.

[0070] Structure of range hood 100:

[0071] The following will refer to Figures 1 to 12 At least a part of is used to illustrate the structure of the range hood in the control method of the household appliance of the present application.

[0072] In one possible embodiment, a range hood 100 includes a range hood body 1, a flap assembly 2, and an image acquisition assembly 3. The range hood body 1 defines a chamber, and the flap assembly 2 is movably disposed on the range hood body 1 and capable of covering the chamber. When the range hood 100 is in operation, the flap assembly 2 is open relative to the chamber. The fan of the range hood body 1 draws fumes and other gases within the kitchen space (e.g., above the stove) into the chamber and out of the kitchen space via the exhaust assembly. This ensures air quality within the kitchen space, such as improving air cleanliness and preventing excessive temperatures within the kitchen space. The image acquisition assembly 3 is primarily configured to capture image data within its field of view, such as image data related to the current cooking process. Based on this image data, operating parameters of the range hood 100 and / or operating parameters of other devices related to the current cooking process can be adjusted to optimize cooking performance and enhance the cooking experience. For example, the opening degree of the flap assembly 2, the speed of the fan, etc. can be adjusted, and related parameters of other equipment such as the fire power of the stove, the exhaust parameters of the oven, etc. can also be adjusted.

[0073] Since gases such as oil smoke usually have a certain degree of turbidity and carry heat. In view of this, in the embodiment of the present application, the image acquisition component 3 is arranged at a position close to the flap component 2. In this way, when the range hood 100 is in working state, there is less gas flowing through the area of ​​the image acquisition component 31. Therefore, the cleanliness and temperature can be guaranteed. Specifically: On the one hand, the image acquisition component 3 usually needs to be in a relatively clean state to ensure the reliability of the collected image data. For example, oil stains on the outer surface of the cover may affect the collected image data; on the other hand, in order to ensure the operational reliability of the image acquisition component 31, the temperature of the environment in which it is located usually needs to be within a certain temperature range (such as not more than 85°C).

[0074] It is understandable that those skilled in the art can determine the structural form of the image acquisition assembly 3, the number of components it includes, and its placement at any position near the flap assembly 2 based on actual needs. For example, the image acquisition assembly 3 can be placed on the outside or inside of the chamber. The image acquisition assembly 3 can include one or more components. If it includes multiple components, all of them can be placed on the outside or inside of the chamber, or some can be placed on the outside of the chamber and some on the inside of the chamber. Taking the example of a roughly rectangular structure of the outer edge of the flap assembly 2, the image acquisition assembly 3 can be placed near the four edges of the rectangular structure, or at any position within the surface of the flap assembly 2. Exemplarily, the flap assembly 2 includes a pivot side 201, a free side 202 (opposite to the pivot side), and two structural sides located at both ends of the pivot side 201 / free side 202. For example, the image acquisition assembly 3 can be placed at any position near the pivot side 201, the free side 202, or the structural side. The image acquisition component 3 can be set on the existing structure of the range hood main body 1, or a structure as a carrier for mounting the image acquisition component 3 can be added to the range hood main body 1. If necessary, the image acquisition component 3 can also be set in a structural form that has no connection relationship with the range hood main body 1, such as fixing the carrier to other reasonable positions. For example, in this example, a hinge component is provided at a position close to one side of the flap assembly along the width direction, such as the hinge component can be fixed to the first / second side plate of the second part or the top of the base. Accordingly, the free side at this time can be understood as: the side that gradually approaches the user during the opening process of the flap assembly or the side that is consistent with the movement trend of the open state. Accordingly, the pivot side at this time should be the other side opposite to the free side, which moves along with the movement of the free side. It is called a pivot side because in the traditional flipping movement, a movement similar to the current flipping effect can also be achieved by providing a rotating shaft, hinge, etc. at a position corresponding to the pivot side.

[0075] In this embodiment, the image acquisition component 31 is disposed within the chamber and is positioned at an edge of the flap assembly 2 near its pivoting side 201. Alternatively, the image acquisition component 31 may be disposed at the bottom of an oil receiving structure 1251, such as an oil screen (in this case, the image acquisition component 31 is near the free side 202 of the flap assembly 2), in the middle of the oil screen (in this case, the image acquisition component 31 is near the inner surface of the flap assembly 2), or outside the chamber (e.g., near the ambient light assembly 51, near the rear oil cup 127, near either side, etc.).

[0076] In this example, the range hood body 1 is a structure that can be raised and lowered and is more suitable for embedded installation. Specifically, the range hood body 1 includes a first portion 11 at the top and a second portion 12 at the bottom. The second portion 12 is arranged on the second portion 12 in a lifting manner, and the flap assembly 2 is arranged below the second portion 12 in an openable and closable manner. The first portion 11 at the top is fixed in a cabinet, and the second portion 12 moves downward relative to the first portion 11 when the range hood 100 is in operation, thereby partially extending out of the cabinet. The second portion 12 moves upward relative to the first portion 11 when the range hood 100 is not in operation, thereby retracting into the cabinet. In this way, when the range hood 100 is not in operation, the range hood 100 as a whole is in the cabinet in an embedded installation manner. Obviously, this structural form is only an exemplary description of the range hood 100. Those skilled in the art can determine the structural form of the range hood 100, the setting position of the flap assembly 2 on the range hood body 1, etc. according to actual needs. For example, the range hood 100 can be a traditional top-suction range hood 100 (the range hood body 1 is in a fixed posture), a side-suction range hood 100, etc.

[0077] Among them, the flap assembly 2 can be placed in an open state or a non-open state relative to the range hood main body 1 by means of rotation, a combination of rotation and other movements, and other movements. Taking only flipping (rotation along a certain axis) as an example, it can be flipped relative to any reasonable axis of the range hood main body 1, and those skilled in the art can adopt any reasonable pivot connection structure / assembly / mechanism (such as hinges, rotating shafts, rotating modules (such as gear pairs, etc.)) according to actual needs to realize the flipping movement of the flap assembly 2 relative to the range hood main body 1. In other words, under the premise of ensuring that the flap assembly 2 can switch between the open state and the non-open state relative to the range hood main body 1, this application does not limit the structure used for switching and the corresponding movement method.

[0078] In one possible embodiment, the flap assembly 2 includes a pivot side 201, and the flap assembly 2 is connected to the range hood body 1 in an openable and closable manner at a position corresponding to the pivot side 201, and the image acquisition assembly 3 is arranged at a position of the range hood body 1 close to the pivot side 201 of the flap assembly 2. When the range hood 100 is in a non-working state, the flap assembly 2 can cover the chamber at the bottom of the range hood body 1. For example, the image acquisition assembly 3 can be arranged on the outside or inside of the chamber. As in this example, the image acquisition assembly 3 is accommodated in the chamber. In this way, when the range hood 100 is in a non-working state, it can prevent gases such as oil smoke in the kitchen space from reaching the surface of the image acquisition assembly 3, thereby ensuring the cleanliness of the image acquisition assembly 3.

[0079] In one possible embodiment, the second part 12 includes a base 121 and a first side panel 122, a second side panel 123, and a front panel assembly 124 disposed on the base 121. For example, in this example, the base 121 includes an integrally formed top panel and a rear panel (such as a top and rear panel). Obviously, the base 121 can also be roughly a frame structure, and the front panel assembly 124, the first side panel 122, the second side panel 123, the top panel, and the rear panel can be disposed thereon or integrally formed therewith. The first side panel 122 and the second side panel 123 are disposed on both sides of the front panel assembly 124. For example, the first side panel 122 and the second side panel 123 can be fixedly connected to the base 121 by means such as screwing from the inside. For example, when splicing, the connection between the different parts that need to be screwed can be beveled to facilitate screwing and fixing. A wiring space 1211 is provided or formed on the inner side of the second portion 12, and related wiring harness components (such as but not limited to wiring harnesses associated with the image acquisition component 3 and the lighting component 4) are arranged in the wiring space 1211. In this example, a wiring groove is fixedly provided on the inner side of the rear portion of the base 121 near the upper portion, and the wiring groove and the base 121 form the wiring space 1211 for the wiring harness components.

[0080] In one possible embodiment, the image acquisition assembly 3 includes an image acquisition component 31, such as a camera assembly. In this example, an image acquisition bracket 32 ​​is disposed within the chamber of the range hood body 1, and the image acquisition component 31 is mounted on the image acquisition bracket 32. For example, if a first mounting position 321 is provided on the image acquisition bracket 32, the image acquisition component 31 is mounted on the image acquisition bracket 32 ​​at a position corresponding to the first mounting position 321. For example, when the flap assembly 2 is open, image data captured by the image acquisition component 31 can be used to determine whether a pot placed on the stove is overflowing, burning dry, or experiencing other issues.

[0081] In this example, when assembled, the image acquisition component 31 is positioned approximately in the middle of the range hood 100. The image acquisition component 31 is mounted in a generally vertical orientation, meaning that the image acquisition component 31 "looks directly" at the area directly below it to capture cooking-related image data. Obviously, the mounting orientation of the image acquisition component 31 can be adjusted appropriately, for example, to a position with an angle between 45° and 90° relative to the horizontal plane, depending on actual needs.

[0082] Among them, for the angles of view that can be captured by the image acquisition component 31, such as in the depth direction and the width direction (the depth / width direction of the stovetop), it should be ensured that image data related to all stove heads can be reliably captured. Exemplarily, the angles of view of the image acquisition component 31 in the depth / width direction can cover the depth / width dimensions of the stovetop. In a specific example, taking the width of the stove as 800mm and the depth as 450mm as a reference, the angle of view along the width direction can cover a stovetop range of 1902mm. Accordingly, the angle of view that can be captured by the image acquisition component 31 in the width direction (the angle formed between the left and right angles) is 102°. The size along the depth direction can cover a stovetop range of 784mm. Accordingly, the angle of view that can be captured by the image acquisition component 31 in the depth direction (the angle formed between the front and rear angles) is 53.4°. Obviously, those skilled in the art can flexibly adjust the angle of view range of the image acquisition component 31 according to actual needs. For example, the camera collects image data within its field of view in a manner that is obliquely directed from front to back and downward (eg, at an angle of 60-90° to the horizontal direction).

[0083] And, in this example, the image acquisition bracket 32 ​​is fixedly arranged on the range hood body 1, and the image acquisition component 31 is arranged on the image acquisition bracket 32 ​​in a fixed posture. Obviously, those skilled in the art can set the image acquisition component 31 on the image acquisition bracket 32 ​​in a movable manner according to actual needs, such as being able to rotate within a certain range relative to the image acquisition bracket 32 ​​(such as the rotation dimension, range, etc. can be adjusted according to actual needs) to adjust the field of view of the image acquisition component 31, or it can move along the image acquisition bracket 32 ​​to collect image data of different areas along the width direction of the stove surface. In addition, if necessary, the image acquisition bracket 32 ​​can be set to a structure that can move relative to the range hood body 1 (such as rotation, telescopic movement, etc.) to better ensure the performance of the image acquisition component 3.

[0084] In one possible embodiment, the camera assembly mainly includes an image acquisition part 311 (such as generally including a camera (image acquisition module) and a PCB board assembly (image acquisition module control board), and the PCB board assembly is provided with a SOC (System-on-Chip)) and a shell 312. For example, if the shell 312 is provided on the image acquisition bracket 32, the image acquisition part 311 is provided in the shell 312 and can collect cooking-related image data within a preset range within a preset field of view.

[0085] In a possible embodiment, the shell 312 includes a first shell 3121 and a second shell 3122 connected to each other. For example, in this example, the first shell 3121 is a cover shell, and the second shell 3122 is a back cover. The cover shell and the back cover form an installation space that can accommodate at least a part of the image acquisition part 311. For example, a light-transmitting structure 3123 such as a lens is provided on the cover shell to ensure the cleanliness of the image acquisition part 311 while ensuring that the image acquisition part 311 can collect image data through the lens.

[0086] Exemplarily, shell mounting structures 3124 are respectively provided on both sides of the cover (along the length direction of the image mounting bracket). For example, in this example, the shell mounting structure is a structure with mounting holes extending from both ends of the cover (such as ears). For example, shell reinforcement structures such as reinforcing ribs are provided on the shell mounting structure to improve the strength of the ears, such as effectively preventing problems such as breakage of the camera assembly when it is assembled. For example, in this example, on the one hand, a PDEM surface with a thickness of about 2 mm is adhered to the outer edge of the cover on the side close to the PCB board assembly. Based on this, good sealing performance between the image acquisition part 311 and the cover can be ensured by squeezing cotton. On the other hand, a plurality of screw columns are provided on the cover. Exemplarily, the cover is respectively provided with first screw columns 3125 at positions roughly corresponding to the four top corners of the back cover. For example, in this example, two screw columns are located on the inner side of the cover, and two screw columns are located on the outer side of the cover. In this way, a fixed connection between the cover and the back cover can be achieved by means of the cooperation between the screws and the screw columns. Exemplarily, the cover is provided with a receiving hole (a cylindrical hole with a certain length in the axial direction) on the side away from the back cover that can be adapted to the front structure of the camera. Based on this, in this example, the installation process of the image acquisition component is roughly as follows: after inserting the bottom of the camera into the cylindrical hole, the camera can be pre-positioned on the shell. On this basis, the PCB board assembly is fixed to the cover by means of fasteners such as screws. Exemplarily, four second screw columns 3126 for fixing the PCB board assembly are provided in the cover. Afterwards, the back cover is fixed to the cover by means of the cooperation of the screws and the first screw columns. Finally, at the position corresponding to the ear, the image acquisition component is fixed to the position of the image acquisition bracket corresponding to the first installation position by means of fasteners such as screws.

[0087] In one possible embodiment, the image acquisition bracket 32 ​​serves as a mounting carrier for the image acquisition component, and its cross-section is roughly a U-shaped structure. As in this example, the cross-section of the middle part of the U-shaped structure is roughly a V-shaped structure, and an obtuse angle is roughly formed between the two end structures located at both ends of the V-shaped structure. Among them, two second mounting positions 322 (such as roughly long strip holes) for mounting the lighting lamp are provided on the U-shaped structure, and the aforementioned first mounting position 321 (such as roughly a rectangular hole) for mounting the image acquisition component is roughly located between the two long strip holes. Obviously, those skilled in the art can determine the structural form of the image acquisition bracket and its first / second mounting position according to actual needs, such as the cross-section of the middle part of the U-shaped structure is roughly a planar structure, etc.

[0088] Exemplarily, a first mounting structure 3211 is provided (e.g., by welding) on ​​the inner side of the image acquisition bracket at a position corresponding to the rectangular hole. Exemplarily, the first mounting structure is a bracket that is roughly a strip-shaped structure and includes two brackets located on both sides of the rectangular hole. The two ears on the shell and the brackets at the corresponding positions are fixedly connected by means of fasteners such as screws, thereby achieving fixation of the image acquisition component on the image acquisition bracket.

[0089] Exemplarily, a second mounting structure 3221 is provided on the inner side of the image acquisition bracket at a position corresponding to the long hole. Exemplarily, the second mounting structure is roughly a U-shaped mounting frame that is compatible with the rear side of the lighting lamp. If a claw is provided on the lighting lamp, the lighting lamp can be fixed on the image acquisition bracket by extending the claw into the clamping hole provided on the mounting frame.

[0090] Obviously, the aforementioned fixing methods and specific implementations of the fixed connection are merely illustrative. Those skilled in the art can determine the structural form of the image acquisition bracket, the method for fixing the image acquisition component / light to the image acquisition bracket, and other aspects based on actual needs. For example, the fixing method of the image acquisition component to the image acquisition bracket can be replaced with a snap-on connection instead of a screw connection, or other implementation methods can be used to achieve the screw connection between the image acquisition component and the image acquisition bracket. Obviously, the screw column can also be configured as another structure, such as a mounting hole.

[0091] In one possible embodiment, a smoke-collecting cavity mainly used for collecting smoke is formed in the chamber, such as an oil receiving assembly 125 is provided at a position corresponding to the top of the smoke-collecting cavity, such as the oil receiving assembly 125 includes an oil receiving structure 1251 such as an oil net, such as an oil receiving connection structure 1252 is provided at a position of the oil receiving structure 1251 near the first / second side plate in a fixed connection or integrally formed manner, such as the oil receiving connection structure 1252 is roughly a plate-like structure, such as the plate-like structure is fixedly connected to the first / second side plate on the corresponding side. For example, the oil receiving assembly 125 is provided with an oil guide assembly 126 at a position near its upstream side. Exemplarily, the oil receiving assembly 125 is arranged downwardly and roughly from front to back, and the oil guide assembly 126 is arranged on the front side of the oil receiving assembly 125. For example, a long strip hole serving as a hinge channel of the hinge assembly 21 is provided on the oil receiving and connecting structure 1252, and an elastic structure 1253 such as a rubber part (having strip holes, mesh holes, etc.) is removably provided at a position corresponding to the long strip hole of the oil receiving and connecting structure 1252 to prevent oil droplets from entering the smoke collecting chamber from the larger long strip hole.

[0092] In one possible embodiment, the oil guide assembly 126 includes an oil guide member 1261. For example, the oil guide member 1261 is a plate-like structure arranged downwardly and tilted from front to back. For example, oil droplets entering the chamber (e.g., from the first portion 11 above) can be caught by the oil guide member 1261 and directed to the downstream oil receiving assembly 125. For example, a plurality of notches (e.g., four in this example) are provided near the front of the base 121 to facilitate the installation and fixation of the oil guide member 1261 on the base 121.

[0093] In one possible embodiment, the oil guide assembly 126 further includes a connecting member 1262. As in this example, the connecting member 1262 is generally a strip-shaped structure, and the connecting member 1262 is fixedly disposed on the oil guide member 1261. The image acquisition bracket 32 ​​is fixedly connected to the oil guide member 1261 via the connecting member 1262. For example, the cross-section of the connecting member 1262 is generally L-shaped, with the first portion 11 of the L-shaped structure (such as the portion disposed generally horizontally in the figure) being disposed on the oil guide member 1261 by means of fasteners such as screws, and the long side of the image acquisition bracket 32 ​​being disposed on the second portion 12 of the L-shaped structure (such as the portion disposed generally longitudinally in the figure) by means of fasteners such as screws. In this way, the image acquisition bracket 32 ​​is fixedly connected to the oil guide member 1261 via the connecting member 1262.

[0094] In one possible embodiment, a base reinforcement structure 1212, such as a reinforcement beam, is provided at a position corresponding to the rear lower portion of the base 121. The base reinforcement structure 1212 is fixedly connected to the base 121, the first side panel 122, and the second side panel 123, respectively, to ensure that the second portion 12 as a whole (the portion near the bottom) has high strength. For example, the reinforcement beam includes a mounting portion 12121 near the top, a connecting portion 12122 near the bottom, and an intermediate portion 12123 between the two. The mounting portion is used to mate with the lower side of the oil receiving assembly, the connecting portion is mainly used for fixed connection to the aforementioned base and the first / second side panels, and the intermediate portion can enhance the strength of the base reinforcement structure to a certain extent and enable the corresponding mating relationship between the mounting portion and the connecting portion to be achieved. As in this example, the mounting portion is roughly a U-shaped structure with the opening facing the oil receiving assembly, the middle portion is roughly a U-shaped structure with the opening opposite to the mounting structure, and the connecting portion is roughly an L-shaped structure. The vertical portion of the L-shaped structure is connected to the bottom of the rear plate of the base, and the two ends of the vertical portion are fixedly connected to the inward flanges of the rear side of the first / second side panel.

[0095] Obviously, the above-mentioned base reinforcement structure consisting of the mounting portion, the connecting portion, and the middle portion is merely an exemplary description. Those skilled in the art can determine its structural form and connection relationship with the base / first side panel / second side panel based on actual needs. For example, it may include, but is not limited to: replacing the middle portion with another structural form such as an arc-shaped plate or a corrugated plate; the connecting portion directly forming a U-shaped structure with an inner side inclined inward, the connecting portion directly connected to the mounting portion (this can be considered as omitting the middle portion); and the connecting portion having flanges extending forward at both ends, which are fixedly connected to the inner or outer side of the first / second side panel.

[0096] In one possible embodiment, the oil receiving assembly 125 is installed within the chamber (e.g., in this example, the oil receiving assembly 125 is located within the portion of the chamber corresponding to the second portion 12) as follows: a magnetic assembly is disposed near the bottom of the oil guide member 1261. In this example, the magnetic assembly includes multiple magnetic components. The aforementioned mounting portion 12121 of the reinforcing beam forms a strip-shaped groove that serves as the mounting location for the oil receiving assembly. Obviously, the oil receiving assembly mounting location may also have an L-shaped structure, a multi-point coupling structure, or the like. In this manner, the upper end of the oil receiving assembly 125 can be connected to the oil guide member 1261 via magnetic attraction (multi-point connection), while the lower end of the oil receiving assembly 125 can be inserted into the groove of the reinforcing beam. Exemplarily, a first mating feature 12124, such as an upwardly protruding strip-shaped boss, is provided on the sidewall (the wall near the bottom) of the groove. Correspondingly, a second mating feature 12125, such as a plurality of downwardly protruding bumps, is provided on the lower surface of the lower end of the oil receiving assembly 125. This ensures that a certain distance between the oil receiving assembly 125 and the reinforcing beam is maintained when assembled, by resting the bumps on the boss. Obviously, the mating of the boss and the bumps is merely an example; other arrangements could also be two bosses, two opposing curved surfaces, or the boss and bumps being swapped. For example, the reinforcing beam is also provided with a connecting structure 12126, such as a plurality of connecting holes, to ensure that oil droplets reaching the reinforcing beam can continue to flow smoothly to locations such as the oil cup 127 below. For example, lugs are provided at the lower rear portion of the second portion 12 near both sides, such as two lugs roughly symmetrically provided on the second portion 12, and an oil cup 127 for collecting oil is removably provided on the second portion 12 by means of the two lugs.

[0097] In one possible embodiment, the range hood 100 includes a lighting assembly 4. In this example, the lighting assembly 4 is primarily used to provide lighting when the range hood 100 is in operation. Therefore, in this example, the lighting assembly 4 is disposed inside the chamber of the range hood body 1. Alternatively, the lighting assembly 4 may be disposed outside the chamber to provide lighting even when the range hood 100 is not in operation.

[0098] In one possible embodiment, the lighting component 4 is located in the chamber near the image acquisition component 31. For example, since the space in the chamber itself is relatively limited, it can be considered that being set at any position can achieve a certain fill light effect. In this way, a fill light effect can also be provided for the image acquisition component 31, thereby ensuring the quality of the image data collected by the image acquisition component 3, and further ensuring the reliability of the control logic. As in this example, the lighting component 4 is installed in the image acquisition bracket 32. Obviously, it can also be installed in other positions or structures, such as a separate installation carrier such as a mounting seat, a mounting bracket, etc., or the lighting component 4 can be directly set on the range hood body 1, such as on the front wall, the rear wall, the top, etc.

[0099] In one possible embodiment, the lighting assembly 4 includes a first lighting component 41 and a second lighting component 42, which are positioned on either side of the image acquisition component 31. This ensures that the image acquisition component 31 achieves a more uniform fill-in lighting effect when both the first lighting component 41 and the second lighting component 42 are in operation. Furthermore, the fill-in lighting effect of the image acquisition component 31 can be ensured by differentially operating the first lighting component 41 and the second lighting component 42 to meet the differentiated supplementary lighting needs of different local areas of a person.

[0100] As in this example, the first lighting component 41 and the second lighting component 42 are substantially the same, such as both including long strip-shaped lighting lamps, and the two are arranged on both sides of the image acquisition component 31 in a roughly symmetrical distribution manner. Obviously, those skilled in the art can flexibly select the number, structural form, setting position, etc. of the lighting components included in the lighting assembly 4 according to actual needs. When the lighting components include multiple components, the multiple lighting components can be the same or different.

[0101] In this example, the image acquisition bracket 32 ​​is a sheet metal bracket, which is entirely located within the cavity. For example, the illuminator is mounted on the sheet metal bracket by providing a hole in the sheet metal bracket and a claw at the rear of the illuminator. The claw is inserted into the hole to secure the illuminator to the sheet metal bracket.

[0102] In one possible embodiment, the image acquisition bracket 32 ​​is disposed on the second portion 12 in the following manner: the two ends of the image acquisition bracket 32 ​​are respectively disposed on the first side panel 122 and the second side panel 123, and the long side portion (the upper portion) of the image acquisition bracket 32 ​​is disposed on the aforementioned generally strip-shaped connecting member 1262. For example, the connecting member 1262 has a generally L-shaped cross-section, with the first portion 11 of the L-shaped structure (such as the portion disposed generally horizontally in the figure) being disposed on the oil-guiding member 1261 by means of fasteners such as screws, and the long side portion of the image acquisition bracket 32 ​​being disposed on the second portion 12 of the L-shaped structure (such as the portion disposed generally longitudinally in the figure) by means of fasteners such as screws. In this way, the image acquisition bracket 32 ​​can be fixedly connected to the oil-guiding member 1261 via the connecting member 1262. In this way, the image acquisition bracket 32, in addition to serving as a mounting carrier for the lighting assembly 4 and the image acquisition component 31, is also fixedly connected to the oil guide member 1261, the first side plate 122 and the second side plate 123. Therefore, it pulls the structure of the second part 12 near the front, thereby improving the strength of the second part 12.

[0103] In one possible embodiment, the image capture bracket 32 ​​is provided with a bracket reinforcement structure 33, such as a reinforcement plate. In this example, the bracket reinforcement structure 33 is provided near the front and outer sides of the image capture bracket 32. The bracket reinforcement structure 33 is fixedly connected to the first side panel 122, the second side panel 123, and / or the base 121 near the front. The rear portion of the bracket reinforcement structure 33 is fixedly connected to the front of the image capture bracket 32. For example, the front portion of the bracket reinforcement structure 33 is fixed to the first / second side panel. For example, the first and second side panels 122 and 123 each include a side panel main portion 1231, which has a side panel flange 1232 extending inwardly from the front. The front side edges of the bracket reinforcement structure 33 are fixedly connected to the side panel flange 1232 of the first / second side panel at positions corresponding to both ends. The bracket reinforcement structure 33 is also fixedly connected to the side panel main portion 1231 of the first / second side panel at a position near the front and rear, or at a position midway between the front and rear.

[0104] Exemplarily, the support reinforcement structure 33 has a first support reinforcement structure flange 331 and a second support reinforcement structure flange 332 extending from its front and rear, respectively, which are fixedly connected to the first / second side panel and the image acquisition bracket. The main portion of the support reinforcement structure is provided with or extended with a mounting bracket 333, such as a roughly sheet-like structure, near its two ends. Based on this, the front portion of the support reinforcement structure 33 and the side panel flange 1232 of the first / second side panel are fixedly connected by means of fasteners such as screws after the first support reinforcement structure flange 331 covers the side panel flange 1232 at the front. The two ends of the support reinforcement structure 33 are fixedly connected by means of fasteners such as screws. The rear portion of the support reinforcement structure 33 and the side panel flange 1232 of the first / second side panel are fixedly connected in such a manner that the second support reinforcement structure flange 332 and the front flange of the image acquisition support 32 are fixedly connected by means of fasteners such as screws.

[0105] Obviously, the structural form and fixing method of the above-mentioned bracket reinforcement structure 33 are only an exemplary description. Those skilled in the art can flexibly adjust them according to actual needs. The installation method and position of the front part may include but are not limited to: flanges are processed backwards at both ends of the bracket reinforcement structure, and the flanges are directly fixedly connected to the main part of the side panel; the bracket reinforcement structure and the image acquisition bracket have overlapping parts that overlap each other (such as adjusting the direction of screwing at the connection position, increasing the strength of the image acquisition bracket by overlapping, etc.).

[0106] In this way, the bracket reinforcement structure not only improves the stability of the sheet metal bracket, but also increases the strength of the first / second side panels, thereby further increasing the structural strength of the front of the second part, such as being able to ensure the verticality and flatness of the first / second side panels.

[0107] In this example, when assembled, the lighting direction of the lamp is biased toward the lower and rear side of the range hood, i.e., the lighting direction is tilted from top to bottom and from front to back. Obviously, those skilled in the art can flexibly adjust the lighting direction based on actual needs. For example, the lighting directions of the two lamps can be set differently or adjusted.

[0108] In one possible embodiment, the range hood 100 further includes an ambient light assembly 51, which is positioned on the range hood body 1 near the pivoting side 201 of the flap assembly 2. While the image acquisition component 31 primarily captures image data related to the current cooking process, the ambient light assembly 51 conveys information related to the current cooking process to the user (e.g., the operator). Therefore, the image acquisition component 31 can be completely contained within the chamber and need not be within the user's field of view when in operation, whereas the ambient light assembly 51 should radiate light within the user's field of view.

[0109] In one possible embodiment, the ambient light assembly 51 is disposed on the range hood body 1 at a position corresponding to the bottom of the chamber. For example, when the flap assembly 2 is closed, the ambient light assembly 51 is located on the side of the flap assembly 2 closest to the operator (the front side). When the flap assembly 2 is open, the ambient light assembly 51 on the front side can convey information related to the current cooking process to the user. Obviously, the ambient light 512 can also be disposed on the range hood body 1 at a position corresponding to the side of the chamber, or the ambient light assembly 51 can be disposed on both the bottom and side of the chamber.

[0110] In this way, when the range hood 100 is in operation, the operation of the ambient light 512 can provide the user with a visual effect (such as a horse racing effect). Furthermore, when the range hood 100 is in operation, different effects can be provided based on the operating parameters of the range hood 100. That is, a preset mapping relationship can be established between the ambient light 512, the effects, and the operating parameters of the range hood 100. Alternatively, the effects of the ambient light 512 can be adjusted based on the image data collected by the aforementioned image acquisition component 31. That is, a preset mapping relationship can be established between the ambient light 512, the effects, and the image data related to the current cooking process.

[0111] In one possible embodiment, the front panel assembly 124 includes a front glass 1242 and a front glass mounting base 1241. For example, the front glass mounting base 1241 may be a plate-shaped structure, a bracket, etc. The front glass mounting base 1241 is fixedly connected to the first / second side panels, the bracket reinforcement structure 33, etc., thereby ensuring the overall strength of the front portion of the second portion 12. In this example, the front glass mounting base 1241 is generally a plate-shaped structure. A plurality of mounting positions for the front glass 1242 are provided on the front glass mounting base 1241 to facilitate mounting the front glass 1242 to the front glass mounting base 1241. For example, the mounting position for the front glass 1242 is a small boss with a latch hole. A latching structure 1243, such as a buckle, is provided on the back of the front glass 1242. The buckle is attached to the back of the front glass 1242 by adhesive bonding. By inserting the buckle into the latch hole on the small boss, the front glass 1242 can be mounted to the front glass mounting base 1241. Furthermore, a long hole is provided in the middle of the front glass mounting base 1241 to facilitate maintenance / removal of the lighting fixture. A notch is provided in the upper right corner of the front glass mounting base 1241 to facilitate maintenance / removal of the hinge assembly 21.

[0112] In one possible embodiment, the atmosphere light assembly 51 includes an atmosphere light mounting base 511 and an atmosphere light 512. The atmosphere light mounting base 511 is fixedly connected to the range hood body 1 or formed as one piece. For example, in this example, the atmosphere light mounting base 511 is fixedly arranged on the front panel assembly 124. The atmosphere light mounting base 511 forms an atmosphere light mounting space, and at least a portion of the atmosphere light 512 is accommodated in the atmosphere light mounting space. In this way, the embedded installation of the atmosphere light 512 at the bottom of the range hood body 1 can be achieved to a certain extent, thereby achieving the effect of seeing light but not seeing the light to a certain extent. For example, the atmosphere light mounting space can be a circumferentially closed installation cavity (the bottom side is a light-transmitting structure or a light-transmitting area is opened), a circumferentially open installation groove, and other structures.

[0113] In one possible embodiment, the ambient light mounting base 511 and the ambient light 512 are both substantially elongated structures. For example, the ambient light mounting base 511 is formed by extruding an aluminum profile, and its cross-section matches the outline dimensions of the ambient light 512. The ambient light mounting base 511 is fixedly mounted at the bottom of the second portion 12. As in this example, the ambient light 512 can be inserted into the ambient light mounting space from one side. Obviously, other installation methods such as direct push-in from the bottom up can also be used.

[0114] In one possible embodiment, the range hood body 1 further includes a decorative strip assembly 52, such as an ambient light mounting assembly base 511, which is fixedly connected or integrally formed with the decorative strip assembly 52, and the decorative strip assembly 52 is fixedly mounted on the front panel assembly 124. Obviously, those skilled in the art can determine the structural form of the decorative strip assembly 52, the method of fixing it to the front panel assembly 124, and the specific location for achieving the fixed connection based on actual needs. For example, it can be fixedly connected to the front panel assembly 124 at the bottom or back, or fixedly connected to the front panel glass 1242 or the front panel glass mounting base 1241 of the front panel assembly 124.

[0115] In one possible embodiment, the ambient light mounting base 511 and the decorative strip assembly 52 are integrally formed, such as by extrusion molding of an aluminum profile, and the decorative strip assembly 52 is fixedly connected to the front glass 1242 by bonding. Thus, after the ambient light 512 is mounted on the ambient light mounting base 511, the decorative strip assembly 52 including the ambient light assembly 51 is bonded to the front glass 1242 to form a glass assembly including the ambient light 512. The front glass assembly 124 including the ambient light 512 is formed by attaching the glass assembly including the ambient light 512 to the front glass mounting base 1241 by snapping.

[0116] In this example, the trim assembly 52 includes a first trim 521 and a second trim 522 located below the first trim 521. The front surface of the first trim 521 is located in front of the second trim 522 along the thickness direction (roughly forming a step surface), thereby ensuring that the second trim 522 is roughly flush with the front surface of the front glass 1242 in the assembled state. As in this example, a third trim 523 extends forward at a position corresponding to the step surface to play a certain positioning role in the bonding process. Among them, the atmosphere light mounting base 511 is located on the back of the second trim 522, and the front part of the first trim 521 is set on the front glass 1242 by bonding. It can be seen that the first trim functions as a bonding part, the second trim functions as a mounting base for the atmosphere light assembly, and the third trim functions as a positioning part.

[0117] For example, a first adhesive structure, such as 3M double-sided tape, is provided near both ends of the first trim strip 521. Furthermore, a second adhesive structure is provided between the first trim strip 521 and the front glass panel 1242. For example, the second adhesive structure comprises glass glue distributed between the first adhesive structures at both ends of the first trim strip 521. This allows the first trim strip 521 and the front glass panel 1242 to be bonded to each other through multi-point bonding. It can be seen that in this example, the double-sided tape is used to better bond the trim strip assembly 52 (e.g., the ambient light assembly 5) including the ambient light assembly 51 to the glass panel. Obviously, those skilled in the art can determine the specific structural form of the trim assembly 52, the relative position of the atmosphere light assembly 51 and the trim assembly 52, the connection method of the trim assembly 52 and the front panel assembly 124 according to actual needs, such as the atmosphere light mounting base 511 is set on the back of the first trim 521, the materials of the first trim 521 and the second trim 522 are different (such as the material of the second trim 522 is similar to the glass panel), the trim assembly 52 is fixedly connected to the front panel glass 1242 on the step surface between the first trim 521 and the second trim 522 by means of plugging / bonding, etc.

[0118] Relative to the second decorative strip 522, both ends of the ambient light mounting base 511 are respectively retracted by a certain distance ( Figure 12 W), such as the two ends of the atmosphere light mounting base 511 are respectively cut off by machining, so that in the assembled state, the two ends of the second decorative strip 522 in the width direction are roughly flush with the outer surfaces of the first side panel 122 and the second side panel 123, and the two ends of the atmosphere light mounting base 511 are roughly abutted to the inner surfaces of the first side panel 122 and the second side panel 123. In this way, the limitation of the atmosphere light assembly 5 is realized, and at the same time, the atmosphere light 512 in the atmosphere light mounting space 5111 can be protected.

[0119] In one possible embodiment, the ambient light assembly 51 is fixed to the front glass 1242 by bonding. For example, the ambient light assembly 51 has 3M double-sided tape near both ends. This allows the ambient light assembly 51 to be securely bonded to the front glass 1242 using the double-sided tape in addition to the distributed glass adhesive. Obviously, other bonding methods can also be used to bond the ambient light assembly to the front glass.

[0120] As can be seen, in the preferred embodiment of this application, by configuring the range hood 100 with an image acquisition component 3, it is possible to control the parameters of the range hood 100 itself and / or other related devices such as ovens and stoves based on the image data collected by the image acquisition component. For example, by linking multiple devices in the control logic, joint control of the kitchen space can be achieved. In this case, the image acquisition component 3 acts as a "smart eye" serving the control logic of the joint control.

[0121] Furthermore, by positioning the image acquisition component 31 within the chamber near the pivoting side 201 of the flap assembly 2, the operational reliability of the image acquisition component 3 is improved. Specifically, less smoke flows through the image acquisition component 31, thereby ensuring the cleanliness of the image acquisition component 31 and maintaining a minimal temperature in the area surrounding it when the range hood 100 is in operation. In particular, when the image acquisition component 31 is housed within the chamber, it is relatively isolated from the air within the kitchen space when the range hood 100 is not in operation, further ensuring the cleanliness and temperature of the image acquisition component 31. Furthermore, by providing the image acquisition bracket 32, which serves as the mounting support for the image acquisition component 31, with a bracket reinforcement structure 33, the overall strength of the range hood body 1 (in this embodiment, the second portion 12 of the range hood body 1) is enhanced while ensuring the reliable installation of the image acquisition component 31.

[0122] In addition, by setting an embedded atmosphere light component 51 near the bottom of the range hood body 1, it is expected that the effect of the atmosphere light 512 can be provided to the user in a way that the light is visible but the light is not. By integrating the atmosphere light mounting base 511 and the decorative strip component 52 of the atmosphere light component 51, the integrated setting of different functional modules is achieved. In addition, a first bonding component is formed by bonding the atmosphere light assembly 5 including the atmosphere light component 51 and the decorative strip component 52 to the front plate glass 1242. On this basis, a second bonding component is formed by further bonding the bonding component to the front plate glass mounting base 1241. In this way, it is expected to optimize the installation process of the front plate assembly 124 (including the atmosphere light assembly 5). For example, under the premise of ensuring the installation reliability, the installation convenience is improved due to the use of a modular bonding method.

[0123] The structure of the cooker 600:

[0124] The following will refer to Figures 13 to 17 At least a part of the structure of the stove in the control method of the household appliance of the present application is used to illustrate the structure of the stove.

[0125] In one possible embodiment, a stove 600 primarily includes an on-off main valve 61, a proportional valve assembly 62, a gas circuit assembly, and at least one burner. The gas circuit assembly supplies gas to the burner. The on-off main valve 61 is typically located on a main gas circuit 631 of the gas circuit assembly and is primarily used to control the overall gas flow within the gas circuit assembly. The proportional valve assembly 62 is located downstream of the on-off main valve 61 along the gas supply direction and is primarily used to adjust the burner's power.

[0126] In this example, there are three burners, which are respectively designated as the left burner 641, the middle burner 642, and the right burner 643 from left to right according to the orientation shown in the figure. The left burner 641 and the right burner 643 both have a structure in which two gas paths are used to supply gas. For example, the left burner 641 and the right burner 643 both include an outer ring and an inner ring. The gas path assembly includes a first gas path (such as can be called an outer ring gas path) and a second gas path (such as can be called an inner ring gas path) corresponding to the outer ring and inner ring of the left / right burner 643. In this way, the gas can be supplied to the outer ring and inner ring of the burner respectively via the outer ring gas path and the second gas path. The middle burner 642 adopts a structure in which one gas path is used to supply gas. If the middle burner 642 includes an inner ring, the gas path assembly supplies gas to the inner ring of the middle burner 642 via the inner ring gas path corresponding to the middle burner 642. The three burners are each equipped with three proportional valve assemblies 62. The power of the three burners can be adjusted by coordinating the on-off main valve 61 and the proportional valve assemblies 62. Obviously, the number of burners and their gas supply method can be flexibly selected based on actual needs. For example, the center burner 642 can also use a two-way gas supply structure, and the left / right burners can use a single gas supply structure or more than two gas supply structures.

[0127] In this example, the proportional valve assemblies 62 corresponding to the three burners have substantially the same structure. Obviously, different proportional valve assemblies 62 can be configured for different burners based on actual needs. For example, the proportional valve assemblies 62 corresponding to the left / right burners 643 can be different from the proportional valve assembly 62 corresponding to the center burner 642.

[0128] In this example, the stove 600 also includes a control panel 65, a display panel 66, and a wireless communication module 67. The control panel 65 is primarily used to issue parameters such as the opening / closing control of the main valve and proportional valve assembly 62, thereby adjusting the power of the burners. The display panel 66 is primarily used to display operating parameters such as the power of the three burners. The wireless communication module 67 (such as a Wi-Fi module, a Bluetooth module, etc.) is used to connect the control panel 65 to other data sources. On this basis, it is expected that the stove 600 can be linked to other devices. For example, image data captured by image detection components such as a camera assembly installed on the range hood above the stove 600 can be used to determine whether the pot is overflowing. By controlling the operating parameters of the stove 600, the reliability of cooking can be ensured. For example, the image data can be directly transmitted to the control board 65 via the wireless communication module 67 and analyzed by the control board 65 of the stove 600; or the analysis results based on the image data can be transmitted to the control board 65 of the stove 600, and the control board 65 can directly give a corresponding adjustment signal based on the pre-established mapping relationship between the image data and the on-off assembly / proportional valve assembly.

[0129] In one possible embodiment, the proportional valve assembly 62 primarily includes a valve body 621, within which a gas passage is provided for allowing gas flow. The valve body 621 is provided with an inlet valve 6211 and at least one outlet valve. The inlet valve 6211 is provided with an inlet valve 6211, which is primarily used to cooperate with the aforementioned on-off main valve 61 to ensure gas intake into the proportional valve assembly 62. The outlet valve is provided with an outlet valve, and the outlet corresponding to the outlet valve can communicate with the aforementioned outer ring gas path or inner ring gas path. The outlet valve primarily adjusts the amount of gas supplied to the burner by adjusting the opening of the outlet valve, thereby adjusting the burner's firepower. As in this example, there are two air outlet valve ports, which are respectively recorded as the first air outlet valve port 6221 and the second air outlet valve port 6222. Correspondingly, the air outlet valves configured at the first air outlet valve port 6221 and the second air outlet valve port 6222 are respectively recorded as the first air outlet valve 6221 and the second air outlet valve 6222, wherein the first air outlet port (outer ring air outlet) 6251 corresponding to the first air outlet valve port 6221 can be connected to the outer ring air path, and the second air outlet valve port 6222 is located between the air inlet valve 6211 and the first air outlet valve port 6221, and the second air outlet port corresponding to the second air outlet valve 6222 can be connected to the inner ring air path.

[0130] Among them, there is a passage inside the valve body 621, such as the passage includes a first passage 6231 located between the first air outlet valve 6221 and the second air outlet valve 6222, and a second passage 6232 located between the second air outlet valve 6222 and the air inlet valve 6211. In this way, the regulation of the gas in the outer ring gas circuit corresponding to the first air outlet valve 6221 is achieved through the joint regulation of the first air outlet valve 6221 and the second air outlet valve 6222, and the gas in the inner ring gas circuit corresponding to the second air outlet valve 6222 is achieved through the regulation of the second air outlet valve 6222.

[0131] Obviously, the description of the passageway comprising a first passageway 6231 and a second passageway 6232 that are substantially connected in series is merely an exemplary description, and other methods such as parallel connection may also be employed. For example, two first passageways 6231 are provided between the inlet valve 6211 and the first outlet valve 6221, one of which is connected in parallel with the second passageway 6232 and can therefore independently supply gas to the first outlet valve 6221. The other first passageway 6231 has a similar structure to the aforementioned one, forming a gas supply path corresponding to the first outlet valve 6221 by being connected in series with the second passageway 6232. In this way, gas can reach the first outlet valve 6221 via two paths. Based on this, the gas in the outer ring gas path corresponding to the first outlet valve 6221 can be regulated through a combination of independent and joint regulation.

[0132] In one possible embodiment, a connecting structure 624 is provided on the first passage 6231 and / or the second passage 6232. For example, the connecting structure 624 may be a connecting hole formed in the valve body 621, a separately provided pipe, or the like. This allows gas to enter the corresponding gas path even when the on / off main valve 61 and the inlet valve 6211 are open, and even when the first / second outlet valves 6222 are closed, thereby maintaining a certain level of heat in the burner of the stove 600. For each passage, one or more connecting structures 624 may be provided. For example, a multi-point arrangement may be employed to ensure the amount or uniformity of gas intake. The connecting structure 624 may be normally open or switchable. For example, it may be automatically adjusted in a manner similar to the inlet / outlet valves, or it may be manually operated / adjusted. For example, manual adjustment may be performed once before shipment, thus saving mold costs. Alternatively, during the use phase, the connectivity state of the connecting structure 624 is switched by manual adjustment. For example, while ensuring connectivity, the specific opening is adjusted (such as from 100% to 70%) to adjust the firepower of the burner under the corresponding working conditions.

[0133] The upstream and / or downstream sides of the communication structure 624 may have one or more communication ports. For example, if there is one communication port on each of the upstream and downstream sides, the communication structure 624 can be used to connect the gas path corresponding to one gas outlet valve. If multiple communication ports are included, it is expected that one communication structure 624 can connect multiple gas paths. Exemplarily, the downstream side of the communication structure 624 includes two branches, one branch can be connected to the outer ring gas path, and the other branch can be connected to the inner ring gas path.

[0134] In one possible embodiment, the connecting structure 624 is disposed on the second passage 6232 between the inlet valve 6211 and the second outlet valve 6222. For example, the connecting structure 624 is a connecting hole section formed in the valve body 621. In this way, when the on-off main valve 61 / inlet valve 6211 are open and the first / second outlet valves are closed, gas can reach the inner annular gas path via the second passage 6232 and the connecting structure 624 disposed thereon, thereby enabling the burner to provide a certain level of combustion power. In this example, the connecting structure 624 is disposed at a non-centering position of the valve body 621. As can be seen from the figure, the connecting structure 624 is located to one side of the centering position.

[0135] In one possible embodiment, the second passage 6232 includes a first passage section 62321, which is arranged approximately along the axis of the intake valve 6211, and a second passage section 62322, which is angled with the first passage section 62321. The intake valve 6211 port corresponding to the intake valve 6211 can sequentially communicate with the port of the second outlet valve 6222 via the first passage section 62321 and the second passage section 62322. The communication structure 624 is disposed in the second passage section 62322. By placing the communication structure 624 near the downstream side of the second passage section 62322, the location where the communication structure 624 communicates with the inner ring gas path is closer to the port of the second outlet valve 6222. This allows the gas flow properties to more closely resemble those when the second outlet valve 6222 is open, thereby ensuring gas supply quality. For example, the communication structure 624 can be further disposed in the second passage section 62322 near the port of the second outlet valve 6222 to further ensure gas supply quality. Furthermore, the combination of the two connecting sections ensures a compact structure within the valve body 621 having multiple outlet valves. For example, the structural form of the second passage section 62322 can be appropriately selected based on the structure of the valve body 621, the number of outlet valve ports, and their relative positions. For example, the second passage section 62322 can be a straight line and / or a curve. For example, the second passage section 62322 can be a broken line formed by combining straight lines, a combination of multiple curves, or a combination of straight lines and curves. For example, if the location where the first passage section 62321 connects is a curve, the angle between the first passage section 62321 and the second passage section 62322 can be described using, for example, a tangent line at the connection location.

[0136] In one possible embodiment, the first passage section 62321 is approximately perpendicular to the second passage section 62322. As shown in the figure, the first passage section 62321 is a vertical passage section parallel to the axis of the intake valve 6211, while the second passage section 62322 is a generally horizontal passage section. The connecting structure 624 is generally formed along the wall thickness of the first passage section 62321. Therefore, the axis of the connecting structure 624 is approximately parallel to the axis of the second outlet valve 6222. The axis of the connecting structure 624 can also be adjusted to a curve or a straight line with a predetermined angle relative to the axis of the second outlet valve 6222, depending on actual needs.

[0137] In one possible embodiment, the cross-sectional (radial) dimension of the connecting structure 624 is smaller than the cross-sectional dimension of the gas outlet valve opening, such as no greater than 1 / 25-1 / 10 of the cross-sectional dimension of the gas outlet valve opening, and illustratively, no greater than 1 / 30 of the cross-sectional dimension of the gas outlet valve opening. As a result, the gas flow rate of the gas passage created by the connecting structure 624 is significantly reduced compared to when the first or second gas outlet valves are open. Therefore, a minimal burner power setting can be created based on this gas passage, for example, to prevent flameout during cooking. Alternatively, in certain operating conditions where the gas supply needs to be shut off, cooking reliability can be ensured while preventing flameout.

[0138] In one possible embodiment, the cross-sectional dimensions of the downstream side of the communication structure 624 are greater than or equal to the cross-sectional dimensions of the upstream side. For example, in this example, the communication structure 624 includes a first communication section 6241 on the upstream side and a second communication section 6242 on the downstream side. The cross-sectional dimensions of the first communication section 6241 are substantially the same, while the dimensions of the downstream side of the second communication section 6242 are greater than those of the upstream side. For example, in this example, the upstream side of the second communication section 6242 (e.g., which can be referred to as the first sub-communication section 62421) is generally funnel-shaped, while the downstream side (e.g., which can be referred to as the second sub-communication section 62422) is generally cylindrical. The aforementioned cross-sectional (radial) dimensions of the communication structure 624 being smaller than the cross-sectional dimensions of the outlet valve port should be understood in accordance with the cross-sectional dimensions of the first communication section 6241. Among them, the cross-sectional size of the first sub-connecting section 62421 is not greater than 1 / 10-1 / 5 of the cross-sectional size of the second sub-connecting section 62422 (the maximum cross-sectional size of the second connecting section 6242). For example, the cross-sectional size of the first sub-connecting section 62421 is not greater than 1 / 9 of the cross-sectional size of the second sub-connecting section 62422 (the maximum cross-sectional size of the second connecting section 6242).

[0139] Obviously, the combination of the funnel structure and the cylindrical structure is only an exemplary description of the second connecting section 6242. Those skilled in the art can flexibly adjust it according to actual needs, such as including only the funnel structure.

[0140] Based on the above structure, in this example, taking the proportional valve assembly 62 corresponding to the left / right burner as an example, when the on-off main valve 61 and the air inlet valve 6211 of the proportional valve assembly 62 are open, the firepower of the outer ring fire in the left / right burner can be controlled by adjusting the opening of the first air outlet valve 6221 and the second air outlet valve 6222. By adjusting the opening of the second air outlet valve 6222, the firepower of the inner ring fire in the left / right burner 643 can be controlled. When the on-off main valve 61 and the air inlet valve 6211 of the proportional valve assembly 62 are open and the first air outlet valve 6221 and the second air outlet valve 6222 are both closed, based on the setting of the connecting structure 624, it can be ensured that the inner ring in the left / right burner still has a certain firepower. For example, for the middle burner 642, the first air outlet valve 6221 can be blocked, or the proportional valve assembly 62 corresponding to the first air outlet valve 6221 can be adjusted according to actual needs, such as omitting the first air outlet valve 6221.

[0141] As can be seen, in a preferred embodiment of the present application, the inlet valve port of the proportional valve assembly can communicate with the main on-off valve, and the proportional valve assembly can communicate with the outer / inner ring gas path via the first / second outlet valve ports, respectively, thereby adjusting the ratio of gas output from the outer / inner ring gas path to the corresponding burner. By providing a connecting structure in the second passage between the inlet valve and the second outlet valve, it is possible to ensure that when the first / second outlet valve is closed, the downstream side of the second outlet valve port can still communicate with the inlet valve port. Accordingly, the burner can achieve a minimum power setting. Specifically, when the main on-off valve / inlet valve is open and the first / second outlet valve is closed, gas from the main gas path can flow into the inner ring gas path via the inlet valve, the second passage, and the connecting structure. For example, in extreme situations such as overflowing or imminent overflowing of a cooker, operating the cooker in the minimum power setting can hopefully eliminate such extreme conditions without extinguishing the cooker.

[0142] Based on the range hood and stove structure described above, this application also provides a control method for household appliances. Expanding on the functionality of the ambient light, this method primarily uses image data captured by the image acquisition component on the range hood to control the operating parameters of the stove. This method can, for example, effectively suppress or eliminate overflowing of a pot placed on the stove while cooking. By controlling the range hood parameters, smoke can be promptly discharged from the kitchen, ensuring a pleasant user experience.

[0143] The following uses the example of steaming, boiling, and stewing, where the overflow status of the pot can be used to reflect the current cooking state. Obviously, in situations where the current cooking state is primarily reflected by the concentration / volume of oil smoke, such as frying, baking, and deep-frying, this can also be achieved using the control method of the present application. For example, by primarily adjusting the operating parameters of the range hood, auxiliary adjustments can also be made to the operating parameters of the stove. In this example, the control method of the present application for household appliances implemented in the cloud is used as an example to illustrate the present application.

[0144] Main reference Figure 18 In a possible implementation, the method for controlling a household appliance mainly includes the following steps:

[0145] S1810: Receive operating parameters of the range hood and stove.

[0146] For example, in this example, the operating parameters of the range hood include the operating parameters of the fan and the operating parameters of the ambient light. The operating parameters of the stove include parameters that can reflect the current fire power of the stove.

[0147] S1820: Receive image data of a target area corresponding to a stove, which is acquired by an image acquisition component provided in the range hood.

[0148] S1830: Adjust the operating parameters of the range hood / stove according to the operating parameters of the range hood / stove and the image data collected by the image acquisition component.

[0149] In a possible implementation, step S1830 mainly includes:

[0150] S310: Determine the current cooking state of the cookware according to the image data corresponding to the target area of ​​the cookware collected by the image collection component.

[0151] In this embodiment, the current cooking state is whether the pot is overflowing. For example, the overflow state includes three types: not overflowing, completely overflowing, and about to overflow (rising). Among them, "completely overflowing" and "about to overflow" can be regarded as "yes" situations, while not overflowing is regarded as "no" situations.

[0152] S320: When the cookware is overflowing and the current power of the stove is less than or equal to the preset power, the inlet valve is opened and the outlet valve is closed so that the gas reaches the burner of the stove through the connecting structure. In this case, the stove operates at the minimum power setting configured based on the connecting structure.

[0153] In this embodiment, the preset firepower is the minimum firepower setting among conventional firepower settings. If the current firepower of the stove is greater than the preset firepower, the firepower should be reduced first. If the overflowing condition cannot be suppressed / eliminated after reducing the firepower to the preset firepower, the stove should be operated at the minimum firepower setting constructed based on the connecting structure. If the current firepower is already at the minimum firepower setting among conventional firepower settings, the stove can be operated directly at the minimum firepower setting constructed based on the connecting structure, thereby suppressing / eliminating the overflowing condition without turning off the stove. Since the cross-sectional dimensions of the connecting structure are much smaller than those of the second air outlet valve port, the burner firepower setting generated by the connecting structure can be referred to as the minimum firepower setting of the burner.

[0154] In other words, when the current firepower of the stove is greater than the preset firepower, the adjustment of the current firepower should start from lowering the firepower. Along with the firepower adjustment, the overflow state of the pot should be continuously determined based on the image data of the pot. Assuming that the overflow state has been effectively suppressed at a certain firepower node (greater than the preset firepower), the firepower node can be maintained, or the firepower can be appropriately increased. For example, if the overflow phenomenon is completely eliminated, you can try to increase the firepower. When the firepower is lowered to the lowest firepower level as the preset firepower, the overflow state still cannot be effectively suppressed, then the stove needs to be operated at the minimum firepower level constructed based on the connecting structure.

[0155] In this embodiment, the specific operation mode of the minimum firepower gear is as follows: the on-off main valve 1 and the air inlet valve 211 of the (left / right burner) proportional valve assembly 2 are opened, and the first air outlet valve 221 and the second air outlet valve 222 of the proportional valve assembly 2 are closed. In this way, based on the setting of the connecting structure 24, the inner ring of the burner can still have a certain firepower when the first air outlet valve 221 and the second air outlet valve 222 of the proportional valve assembly 2 corresponding to the burner are closed. For example, the current pot is placed Figure 13 Above the left burner in the figure, the left burner is in operation.

[0156] S330: Adjust operating parameters of the range hood fan according to the current cooking state.

[0157] Exemplarily, based on the image data captured by the image acquisition component, it is determined whether the smoke volume is large. If it is greater than a predetermined smoke volume, the fan speed is increased. Exemplarily, the fan speed is divided into different gears. For example, there is a predetermined mapping relationship between the smoke volume and the fan speed gear.

[0158] S340: Adjust the operating parameters of the ambient light according to the current cooking state. For example, in this example, the operating parameters of the ambient light are adjusted to match the speed level of the fan.

[0159] For example, there is a preset mapping relationship between the operating parameters of the ambient light and the changes in the speed gear of the fan. For example, when the operating parameters of the range hood change (such as skipping gears), the ambient light will show an effect such as "blinking twice for a total of 3 seconds and then returning to a steady light."

[0160] In this way, the current cooking status is determined based on the image data collected by the image acquisition component installed on the range hood. Based on the current cooking status, the operating parameters of the stove and / or range hood are adjusted, and cooking reliability is expected to be ensured through the coordinated adjustment of the range hood and stove. For example, in this example, by incorporating the adjustment of the operating parameters of the ambient light into the control method of this application, the functionality of the ambient light is expanded and the user experience is improved.

[0161] In a possible implementation, step S30 mainly includes:

[0162] S302: Adjust the operating parameters of the range hood according to the image data collected by the image collection part.

[0163] For example, the operating parameters of the range hood can be adjusted based on the smoke level reflected in the image data. For example, when the operating parameters of the range hood change, the ambient light will show an effect such as "blinking twice for a total of 3 seconds and then returning to a steady light."

[0164] As can be seen, in the preferred embodiment of this application, by deploying an image acquisition component on the range hood, the operating parameters of the range hood / stove can be controlled accordingly using the image data it collects. Along with structural improvements, the coordinated control of the range hood and stove optimizes the performance of the home appliance. Simultaneously, the ambient light component participates in control, optimizing the user experience. Details regarding the structural improvements to the image acquisition component and ambient light component on the range hood, as well as the structural improvements to the stove corresponding to the minimum power setting, are described above.

[0165] It should be noted that although the above embodiments describe the various steps in a specific order, those skilled in the art will appreciate that, in order to achieve the effects of the present application, the different steps do not necessarily have to be performed in this order; they can be performed simultaneously or in another order, and some steps can be added, replaced, or omitted. For example, the order of S1810 and S1820 can be swapped or performed simultaneously, and the fan speed is not adjusted when the pot overflows.

[0166] It should be noted that although the control method of the household appliance constructed in the above specific manner is introduced as an example, those skilled in the art will understand that the present application should not be limited to this. In fact, the user can flexibly adjust the relevant steps and parameters in the steps according to the actual application scenario and other situations. For example, the operating parameters of the atmosphere light can also have a preset mapping relationship with the image data. For example, in the case of overflowing pots, an effect such as "flashing, frequency 1Hz, until the alarm is lifted and it returns to normal light" is presented.

[0167] Based on this application, a voice broadcast component such as a magic box can be configured on the stove / range hood, and the user can download the Zhijia APP on a terminal such as a mobile phone. In this way, the user can turn on the range hood and / or stove without contact by operating on the Zhijia APP. For example, turn on the stove and then turn on the range hood at the same time by linking the range hood and stove. During the cooking process, you can also use the video function by entering the device details page of the Zhijia APP, such as directly viewing the recorded video in real time and making a short video (such as sharing it with other users). You can also send a request to the cloud to realize the function of viewing the recorded video in real time and making a short video. Based on the image acquisition component set on the range hood, image data that can be collected to identify the overflow status of the pot above the stove, the status of the pot being removed from the stove, the cooking time that has lasted for a long time, the oil stain status above the stove, etc. can be collected. Based on the recognition results of the image data, the operating parameters of the range hood (such as the speed of the fan, etc.) can be adjusted, and the firepower of the stove can also be adjusted. For example, the instruction to adjust the firepower of the stove is transmitted to the stove main control board via the Bluetooth module. When necessary, the device status of the range hood and stove can be reported to the cloud. For example, the cloud can send reminders to users through the Zhijia APP, or directly remind users in the form of voice broadcasts through the Magic Box. In addition, users can also upload recorded videos / audio related to current cooking to the cloud through the Magic Box. For example, the cloud can recognize the voice, analyze the user's intentions, and send instructions corresponding to the analysis results to the range hood / stove, such as adjusting the operating parameters of the range hood / stove. After adjusting the operating parameters, the video is recorded and the content instructions (such as "the overflow has been resolved", "the cooking time has been long, should I turn off the fire", etc.) corresponding to the voice broadcast method (reply words) of the recorded video are sent to the Magic Box, and the Magic Box will broadcast the corresponding voice to the user. In this way, the reliability of cooking can be guaranteed and the user experience can be improved from multiple aspects.

[0168] Main reference Figure 19In one possible implementation, in the control system of a household appliance, the image acquisition component is connected to the range hood main control board via a bidirectional signal connection, and the image acquisition component is connected to the stove main control board via a wireless communication module such as a Bluetooth module or a Wi-Fi module. Based on this, the performance of the household appliance can be optimized through the smoke and stove joint control method. In addition, the image acquisition component can also be connected to the cloud via a wireless communication module such as a Wi-Fi module via a bidirectional signal connection, thereby uploading image data and range hood / stove operating parameters to the cloud, and receiving adjustment instructions for the range hood / stove operating parameters. Obviously, factors such as the chip type and the implementation method of the signal connection between modules can be flexibly adjusted according to actual needs.
