Description

TECHNICAL FIELD

[0001] The present application relates to a cooking surface cleaning method, a cleaning device and a cleaning system. BACKGROUND

[0002] Now every time using the cooking surface to cook causes similar oil stains, spatter, overflow and other dirt splashing on the cooking surface, under high temperature conditions, dry quickly and solidify on the cooking surface, accumulate for a long time to cause stubborn stains that are difficult to clean.

[0003] At present, the market generally uses the method of wiping the cooking surface in time after finding dirt or after cooking, or using a cleaning agent to assist other cleaning tools to clean stubborn stains. But each time cleaning is time-consuming and laborious, and the cooking surface is in a high temperature environment, often not in time to clean immediately, or difficult to clean thoroughly. There are many brands of cleaning agents, and the cleaning effect is uneven. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the defects of not timely cleaning and difficult to clean the cooking surface in the prior art, and to provide a cooking surface cleaning method, a cleaning device and a cleaning system.

[0005] The present application solves the above technical problems by the following technical solutions:

[0006] A cooking surface cleaning method, the cleaning method comprising:

[0007] Obtaining image information and / or sound information in a working area of the cooking surface;

[0008] According to the image information and / or the sound information, judging the use condition of the cooking surface;

[0009] According to the use condition, controlling the water flow state of the water inlet and the water outlet of the cooking surface, wherein the water inlet and the water outlet are respectively located at both ends of the cooking surface along the length direction thereof.

[0010] In this scheme, the use condition of the cooking surface is judged through the image information and / or the sound information of the cooking surface, and then used as a control reference for controlling the water flow state of the water inlet and the water outlet of the cooking surface, so that the use condition of the cooking surface can be automatically judged, the water flow state of the water inlet and the water outlet can be adjusted in time, the timely processing of the cooking surface is realized, and the dirt, oil stains and the like can be avoided to solidify on the cooking surface, so that the cleaning is convenient.

[0011] Preferably, according to the image information, judging the use condition of the cooking surface comprises:

[0012] Identifying the to-be-processed objects in the image information; the to-be-processed objects include oil stains and foreign matters;

[0013] When the object to be treated is oil stains, the usage condition of the stove surface is determined based on the proportion of oil stains on the water film surface and / or the number of oil stains in the working area of ​​the stove surface.

[0014] When the object to be processed is a foreign object, the usage status of the stove surface is determined based on the area and type of the foreign object within the working area of ​​the stove surface.

[0015] In this solution, by recognizing image information, the condition of the items to be treated on the surface of the stove can be identified. Then, based on the items to be treated, such as oil stains and larger foreign objects, the usage condition of the stove surface can be determined. The water flow state can then be controlled according to the actual usage condition. For example, if there are many items to be treated, the usage condition can be considered that there are many items to be treated on the surface of the stove, which need to be treated.

[0016] Preferably, when the substance to be treated is oil, controlling the water flow status of the stove's inlet and outlet according to the usage includes:

[0017] When the proportion of oil on the water film surface is greater than a first preset value, or the number of oil particles is greater than a second preset value, the water flow rate of the inlet and outlet is increased.

[0018] In this solution, when the proportion or quantity of oil stains exceeds the corresponding preset value, it indicates that the surface of the stove needs to be cleaned. By increasing the water flow rate at the inlet and outlet, the water flow rate can be increased instantaneously, causing the oil stains to flow to the outlet and be discharged outside the working area of ​​the stove surface.

[0019] Preferably, when the object to be processed is a foreign object, controlling the water flow state of the stove's inlet and outlet according to the usage includes:

[0020] When a foreign object is detected, the water flow rate at the inlet is increased within a first preset time to create an impact water flow.

[0021] After the impact is completed, the foreign object in the image information is detected again;

[0022] The water flow status of the stove's inlet and outlet is controlled based on the test results from the retest.

[0023] In this solution, when a foreign object is detected, the water flow rate at the inlet is increased within a first preset time period, thereby creating an impact water flow that moves the foreign object and prevents it from settling in a certain location, which would cause dirt to accumulate at that location.

[0024] Preferably, controlling the water flow state at the inlet and outlet of the stove based on the detection result of the re-detection includes:

[0025] If the foreign object is detected to have moved a preset distance, the inlet and outlet of the stove are controlled to maintain their initial state.

[0026] If the foreign object is detected to be stationary, the foreign object information is recorded and synchronized to the user terminal.

[0027] In this solution, if foreign object movement is detected, it can prevent the foreign object from staying in one position for a long time; if no foreign object movement is detected, feedback is sent to the user terminal for the user to make a decision.

[0028] Preferably, the step of determining the usage status of the stove surface based on the image information and / or the sound information further includes:

[0029] Based on the image information and / or the sound information, and based on the cooking actions and / or cooking sounds within the working area of ​​the cooktop surface, the usage status of the cooktop surface is determined.

[0030] In this solution, image and / or sound information is used to determine the cooking actions and / or sounds in the work area, thereby enabling the determination of whether the stove in the work area is in a condition prone to staining, such as when the stove is in a high-heat stir-frying state or when the stove is overflowing. In these situations, food inside the stove is prone to splashing or flying out and falling into the work area, indicating that the surface of the stove needs to be cleaned.

[0031] Preferably, controlling the water flow status of the stove's inlet and outlet according to the usage includes:

[0032] When the cooking action is identified as a stir-frying action and / or the cooking sound is a stir-frying sound, the water flow rate of the inlet and outlet is increased.

[0033] When the cooking action is identified as an overflow action and / or the cooking sound is an overflow sound, the water flow rate of the inlet and the outlet is increased.

[0034] In this solution, when the system detects that the stove is in a high-heat stir-frying or overflowing state, the water flow rate at the inlet and outlet is increased. This can promptly move the splashed or overflowing stains away, preventing stains from accumulating and making the stove surface easier to clean.

[0035] Preferably, acquiring image and / or sound information within the working area of ​​the cooktop surface includes:

[0036] The infrared temperature measurement and image recognition camera installed above the surface of the stove detects the image information of the stove surface;

[0037] The sound information of the stove is detected by sound recognition sensors placed around the stove.

[0038] In this solution, infrared temperature measurement and image recognition cameras improve detection accuracy and more precisely distinguish the properties of the materials to be processed within the work area, thereby creating appropriate water flow patterns for effective cleaning. Sound recognition sensors, either alone or in combination with image recognition, enhance the accuracy of judging the cooking status.

[0039] Preferably, before acquiring image and / or sound information within the working area of ​​the cooktop surface, the method further includes:

[0040] Determine the current mode, where the current mode includes manual mode and automatic mode;

[0041] When the current mode is manual mode, the water flow state of the inlet and outlet of the stove is controlled to flow according to a preset mode; or the control signal from the user terminal is acquired in real time, and the water flow state of the inlet and outlet of the stove is controlled according to the control information.

[0042] When the current mode is automatic mode, image and / or sound information is acquired within the working area on the surface of the stove.

[0043] In this solution, cooktop cleaning includes manual and automatic modes. In automatic mode, the cooktop surface is automatically detected and identified for its condition, and the water flow is automatically controlled to clean the surface. In manual mode, users can control the water flow rate as needed.

[0044] Preferably, the cleaning method further includes:

[0045] Adjust the grilles at the water inlet and water outlet of the stove to the corresponding preset heights, wherein the height of the grille at the water inlet is higher than the height of the grille at the water outlet;

[0046] Control the water inlet to allow water to enter the working area on the surface of the stove until the water film thickness reaches the height of the grid at the water outlet;

[0047] The water inlet is controlled to pump water, wherein the water inlet's pumping flow rate is greater than the water inlet's inlet flow rate.

[0048] In this solution, by setting the height of the fence and allowing water to enter, a water film can be formed on the surface of the stove in advance. This water film can be formed before cooking, and can accommodate the food to be processed during cooking. It can also make it easier to discharge or push the food to be processed when the water flows in later.

[0049] And / or, the cleaning method further includes:

[0050] After cooking is complete, the height of the grate at the water inlet is lowered below the surface of the stove to drain the water from the surface of the stove.

[0051] In this solution, after cooking is complete, the water on the surface of the stove can be drained by adjusting the height of the grate at the drain outlet, so as to keep the surface of the stove clean and dry afterwards.

[0052] The present invention also provides a cleaning device for the surface of a cooktop, the cleaning device comprising:

[0053] The first module is used to acquire image and / or sound information within the working area on the surface of the stove;

[0054] The second module is used to determine the usage status of the stove surface based on the image information and / or the sound information;

[0055] The third module is used to control the water flow status of the inlet and outlet of the stove according to the usage conditions, wherein the inlet and outlet are located at both ends of the stove surface along its length.

[0056] The present invention also provides a cleaning system for the surface of a cooktop, the cleaning system including the cleaning device described above, and further including a water inlet grille, a water outlet grille, a water inlet flow regulating device, and a water outlet flow regulating device. The water inlet grille is disposed at the water inlet along the width direction of the cooktop surface, and the water outlet grille is disposed at the water outlet along the width direction of the cooktop surface. The water inlet flow regulating device and the water outlet flow regulating device are respectively connected to the water inlet and the water outlet.

[0057] The cleaning system also includes an infrared temperature measurement and image recognition camera positioned above the surface of the cooktop, and a sound recognition sensor positioned around the cooktop.

[0058] Preferably, the cleaning system further includes an inlet height adjusting motor connected to the inlet grille and a water collection height adjusting motor connected to the water collection grille, and the cleaning device is integrated into the inlet height adjusting motor;

[0059] And / or, the cleaning system further includes an isolation strip and a protective ring, wherein the isolation strip is provided on both edges along the length of the cooktop surface; the protective ring is provided around the burner and buttons on the cooktop surface; and the height of the protective ring is not less than the height of the water inlet grille, and the height of the isolation strip is not less than the height of the water inlet grille.

[0060] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0061] The positive and progressive effects of this invention are as follows: by using image information and / or sound information on the surface of the stove, the usage condition of the stove surface can be determined, and then used as a control reference to control the water flow state of the inlet and outlet of the stove. This allows for automatic judgment of the usage condition of the stove surface and timely adjustment of the water flow state of the inlet and outlet, enabling timely treatment of the stove surface. Furthermore, it can prevent dirt, oil stains, etc. from solidifying on the stove surface, making cleaning convenient. Attached Figure Description

Detailed Implementation

[0067] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0068] Example 1

[0069] This invention provides a cleaning system for the surface of cooktops, such as... Figure 1 As shown, the cleaning system includes an inlet grille 110, a drain grille 120, an inlet water flow regulating device 210, and a drain water flow regulating device 220. The inlet grille 110 is installed at the inlet along the width direction L2 of the stove surface, and the drain grille 120 is installed at the drain along the width direction L2 of the stove surface. The inlet water flow regulating device 210 and the drain water flow regulating device 220 are connected to the inlet and the drain, respectively.

[0070] Furthermore, such as Figure 1As shown, the surface of the stove is typically a rectangular plane with one or more burners 2 on it for heating cookware. Other function buttons 3, such as ignition and flame adjustment buttons, are also typically provided on the stove surface. A water inlet grille 110 and a water outlet grille 120 are respectively located at both ends of the length L1 of the stove surface. The water inlet grille 110 is located at one edge and extends along the width L2 of the stove surface; the water outlet grille 120 is located at the other edge and extends along the width L2 of the stove surface. The height H3 of the water inlet grille 110 is greater than the height H4 of the water outlet grille 120, allowing water to flow towards the water outlet grille 120, which corresponds to the water flow direction V1 in the figure.

[0071] like Figure 1 As shown, both edges of the cooktop surface L1 along its length are provided with isolation strips 130 to maintain the water flow height; the height H2 of the isolation strips 130 is not lower than the height H3 of the water inlet grille 110. The burner 2 and button 3 within the cooktop surface are each provided with a protective ring 140 around their circumference; and the height H1 of the protective ring 140 is not lower than the height H3 of the water inlet grille 110. When water flows from the water inlet grille 110 to the water collection grille 120, the height H3 of the water inlet grille 110 is higher than the height H4 of the water collection grille 120. The thickness of the water film at the water inlet grille 110 will be slightly higher than the thickness at the water collection grille 120. By setting the heights of the isolation strips 130 and the protective rings 140 to be no lower than the height H3 of the water inlet grille 110, it is possible to prevent the water film from flowing out of the working area or into the burner 2 and button 3.

[0072] The insulating strip 130 located along the long side of the cooktop surface, and the water inlet grille 110 and water outlet grille 120 located along the short side of the cooktop surface, enclose the edge of the cooktop surface and form the working area of ​​the cooktop surface. The protective ring 140 protects the burner 2 and the buttons 3, preventing water from entering the burner 2 and buttons 3 when water exits from the water inlet grille and water remains on the cooktop surface. The height H4 of the water outlet grille represents the minimum thickness of the water layer formed on the cooktop surface; water only begins to flow out from the outlet after reaching height H4. The water layer covering the cooktop 1 is simply referred to as a "water film".

[0073] In practice, install the isolation strip 130 along the long side of the stove 1 and the water inlet / outlet along the short side, ensuring that water does not leak out of the stove surface from the surrounding area (this can be sealed with waterproof adhesive). No disassembly is required after installation. Place a high-temperature resistant protective ring 140 around the burner head 2. The bottom layer of the protective ring 140 is made of a soft, hydrophobic material, which adheres to the stove surface using its own weight or a suction cup-like effect, ensuring that water does not enter the burner head 2 and thus avoid affecting normal cooking. Therefore, the protective ring 140 of the stove 1 and burner head 2 can be fixed in place and waterproofed. Alternatively, the water-resistant seal can be achieved using the weight of the material itself and the underlying soft, hydrophobic material. It can be installed before cooking and removed after cooking.

[0074] like Figure 1 As shown, the inlet water flow regulating device 210 and the outlet water flow regulating device 220 are connected to the inlet and outlet water respectively. These devices can be water pumps. The cleaning system may also include an inlet water storage tank 310 and an outlet water storage tank 320. The inlet water storage tank 310 contains clean water and is connected to the inlet water flow regulating device 210. The inlet water flow regulating device 210 can supply water to the inlet grate 110 at a flow rate of Q1 to control the inlet water flow rate. The inlet water storage tank 310 can also be connected to an inlet water pipe. The outlet water storage tank 320 stores wastewater and is connected to the outlet water flow regulating device 220. The inlet water flow regulating device 210 can pump water from the outlet grate 120 at a flow rate of Q2. The outlet water storage tank 320 can also be connected to an outlet water pipe.

[0075] like Figure 1 As shown, the cleaning system also includes an inlet height adjusting motor 410 connected to the inlet screen 110 and a water collection height adjusting motor 420 connected to the water collection screen 120. The inlet height adjusting motor 410 and the water collection height adjusting motor 420 can adjust the height of the inlet screen 110 and the water collection screen 120 respectively, thereby controlling the free raising and lowering of the inlet screen 110 and the water collection screen 120. Furthermore, the isolation belt 130 can also be equipped with a height adjusting device for height adjustment.

[0076] Preferably, the control device in the cleaning coefficient, i.e. the cleaning device, is integrated into the inlet water height adjustment motor 410; and it can communicate wirelessly with the user terminal, for example, through Bluetooth connection.

[0077] like Figure 2 As shown, the cleaning system also includes an infrared temperature measurement and image recognition camera 520 installed above the cooktop surface and a sound recognition sensor 510 installed around the cooktop 1.

[0078] In practice, a range hood is typically installed directly above the cooktop, and an infrared temperature measurement and image recognition camera 520 can be mounted on it. If a range hood is not installed, it can also be mounted on other structures. For example... Figure 2 As shown, infrared temperature measurement and image recognition cameras 520 are installed on both sides of the range hood to avoid obstruction of the camera's recognition content during cooking. The camera can be pre-loaded with an image recognition model trained by machine learning. The camera can recognize images of the stove area, and infrared temperature measurement is used to more accurately distinguish between clean water flow and oil stains. The content to be recognized is a special scene, including: 1) the distribution of oil stains in the water film, such as: the proportion of oil stains on the surface of the water film a, and the number of oil stains b;

[0079] 2) Whether stir-frying action occurs (c) (0: no, 1: yes), whether overflow occurs (d) (0: no, 1: yes); 3) Identification of larger foreign objects, such as large pieces of meat shreds (area S, which can be calculated based on the size of the stove 1 input by the user; type of foreign object k) falling, and no obvious displacement within 1 second (example value) (such as 50% of its own size).

[0080] The sound recognition sensor 510 can be installed in the middle of the range hood. The sound recognition sensor 510 can be preloaded with a sound recognition model trained by machine learning to help identify special scenarios: it can identify whether there is a stir-frying sound e (0: no, 1: yes) and whether there is an overflowing sound f (0: no, 1: yes).

[0081] The inlet water flow regulating device 210, the outlet water flow regulating device 220, the inlet water height regulating motor 410, the outlet water height regulating motor 420, the sound recognition sensor 510, and the infrared temperature measurement and image recognition camera 520 communicate via a 2.4G network. The inlet water height regulating motor 410 is the main computing unit; all other devices are connected to it. The inlet water height regulating motor 410 receives data reported by each device and sends control commands to them. It also has a Bluetooth module, allowing it to connect to user devices such as mobile phones. This system is compatible with most stoves 1, eliminating the need to purchase a separate stove 1.

[0082] Example 2

[0083] This invention also provides a method for cleaning the surface of a cooktop, which can use the cleaning system described in Embodiment 1 above. Figure 3 As shown, the cleaning methods include:

[0084] S100: Acquire image and / or sound information within the working area of ​​the cooktop surface;

[0085] S200: Determine the condition of the cooktop surface based on image and / or sound information;

[0086] S300: Controls the water flow status of the inlet and outlet of the stove 1 according to the usage, wherein the inlet and outlet are located at the two ends of the stove surface along its length L1.

[0087] By analyzing image and / or sound information from the cooktop surface, the usage status of the cooktop surface is determined. This information serves as a control reference for the water flow status at the inlet and outlet of the cooktop 1. This allows for automatic assessment of the cooktop surface's condition and timely adjustment of the water flow at the inlet and outlet, enabling timely surface cleaning and preventing dirt and grease from solidifying on the cooktop surface, thus facilitating cleaning. The working area refers to the area on the cooktop surface that can be covered with a water film, excluding the area used for cooking operations. This is the area enclosed by the inlet grille 110, outlet grille 120, and isolation strip 130 in Embodiment 1.

[0088] In a preferred embodiment, prior to step S100, the method further includes:

[0089] S11: Determine the current mode, which includes manual mode and automatic mode;

[0090] S12: When the current mode is manual mode, control the water flow state of the inlet and outlet of the stove 1 to flow according to the preset mode; or obtain the control signal from the user terminal in real time, and control the water flow state of the inlet and outlet of the stove 1 according to the control information.

[0091] S13: When the current mode is automatic, image and / or sound information is acquired within the working area on the surface of the stove.

[0092] The cooktop cleaning function includes manual and automatic modes. In automatic mode, it can automatically detect and identify the condition of the cooktop surface and automatically control the water flow to clean the surface. In manual mode, users can control the water flow rate as needed.

[0093] Furthermore, when the current mode is manual or automatic, the cleaning method may also include an initialization process for each device. This initialization process can be adjusted manually or automatically based on preset parameters, and may specifically include the following steps:

[0094] S14: Adjust the grilles at the water inlet and water outlet of the stove 1 to the corresponding preset heights, wherein the height of the grille at the water inlet is higher than the height of the grille at the water outlet;

[0095] S15: Control the water inlet to allow water to enter the working area of ​​the stove surface until the water film thickness reaches the height of the grid at the water outlet;

[0096] S16: Control the water intake pumping, wherein the water intake pumping flow rate is greater than the water inlet flow rate.

[0097] By setting the height of the grille and allowing water to enter, a water film can be pre-formed on the surface of the stove. This water film can hold the food being processed during cooking and also makes it easier to drain or push the food when the water flows later.

[0098] In the manual mode of S12 described above, the user can adjust the height H3 of the inlet grate 110 via the inlet height adjustment motor 410 and the height H4 of the outlet grate 120 via the outlet height adjustment motor 420 to adjust the water film thickness within the working area. The user can also manually adjust the flow rates of the inlet flow regulating device 210 and the outlet flow regulating device 220 to adjust the water flow velocity V1. In manual mode, the infrared temperature measurement and image recognition cameras 520 and the sound recognition sensor 510 on both sides can remain silent or not be installed at all. Furthermore, there is no requirement for communication between the devices.

[0099] Specifically, before cooking, open the water inlet to allow water to enter, adjusting the water flow rate. The heights of H1, H2, H3, and H4 can be adjusted, or you can set a suitable flow rate and height based on experience. Ensure there is sufficient clean water in the clean water tank and sufficient remaining capacity in the waste water tank. Once the water covers the entire surface of the stove and begins to flow from the inlet, you can begin cooking. Maintain a continuous water flow during cooking.

[0100] In the automatic mode of S13 above, all the above devices are connected to the control device via a 2.4G network, such as the water inlet height adjustment motor 410, and communication between the devices is normal.

[0101] The mobile phone connects to the water inlet height adjustment motor 410 via Bluetooth. 1) It is used to set basic parameters, namely the height H1 of the protective ring 140, the height H2 of the isolation strip 130, the length L1 of the stove 1 in the length direction, and the length L2 of the stove 1 in the width direction, to ensure that water film does not overflow the stove surface during automatic adjustment, and for other calculations; 2) It is used to view the camera's field of view and manually adjust the camera angle to ensure that both cameras can capture the complete boundary of the stove 1; 3) It can set and adjust the default height of the water inlet grille 110 and the water outlet grille 120, the default flow rate of the water inlet flow adjustment device 210 and the water outlet flow adjustment device 220, the default percentage of oil on the water film surface a' (i.e., the first preset value below), and the default number of oil spots b' (i.e., the second preset value below). After setting the above two items, the data is saved to each device. If the user does not actively set the above default parameters, the default parameters built into the application device will be used. In addition, during the cooking process in automatic adjustment mode, users can also manually adjust the above parameters, including the fence heights H3 and H4, and the water pump flow rates Q1 and Q2.

[0102] 1) By pressing the start button 3 on the motor height adjustment motor, the cooking process is started. The water inlet height adjustment motor 410 and the water outlet height adjustment motor 420 automatically adjust the corresponding gates to the corresponding default heights. The water inlet flow adjustment device 210 starts to release clean water at the corresponding default flow rate, and the water outlet flow adjustment device 220 extracts wastewater at the corresponding default flow rate.

[0103] 2) When the water film thickness reaches H4, the water flow begins to cross the water collection fence 120 and flows into the water collection storage tank 320 through the water collection flow regulating device 220.

[0104] 3) During the cooking process, the flow rates Q1 and Q2 should always be kept so that Q2 is slightly greater than Q1 (the specific ratio of Q1 / Q2 can be adjusted) to ensure that there is no long-term accumulation of water and overflow.

[0105] The device allows for timely replenishment of water to the inlet storage tank 310 and timely emptying of the outlet storage tank 320. All storage tanks in this system can be replaced by direct connection to a water pipe.

[0106] In automatic mode, data on the settings parameters such as flow rate and height for each user's different cooktop sizes are reported to the cloud server via the connected mobile phone. In manual mode, the user must actively connect the height adjustment motor via Bluetooth and establish a 2.4G network connection between each device, and allow the corresponding settings parameters to be reported to the cloud server. If the flow rate and height parameters used by the user are not adjusted for 10 consecutive times (example values), the parameters are considered reasonable for the cooktop size and can be added as a recommended setting template to the setting template store. Users can browse the template content in the store via their mobile phones. Users can bookmark the templates in the store and apply them to their own devices, and can recommend or dislike the templates; the templates are categorized according to different cooktop sizes and ranked from highest to lowest based on the number of recommendations.

[0107] Therefore, the water film thickness and water flow rate can be adjusted manually or automatically to adapt to different cooking scenarios. Based on user intervention, the default parameters for specific scenarios are automatically adjusted to better suit each user's usage habits and preferences. Furthermore, based on extensive user data, the device's setting parameter templates are ranked and recommended for easier user selection.

[0108] In a preferred embodiment, step S200 above, determining the usage condition of the stove surface based on image information, includes:

[0109] S210: Identify objects to be processed within image information; objects to be processed include oil stains and foreign objects.

[0110] S221: When the object to be treated is oil stains, the usage condition of the stove surface is judged based on the proportion of oil stains on the water film surface and / or the number of oil stains in the working area of ​​the stove surface.

[0111] S222: When the object to be processed is a foreign object, the usage status of the stove surface is determined based on the area and type of the foreign object within the working area of ​​the stove surface.

[0112] By recognizing image information, the condition of the items to be treated on the surface of the stove can be identified. Based on the items to be treated, such as oil stains and larger foreign objects, the usage condition of the stove surface can be determined. The water flow can then be controlled according to the actual usage condition. For example, if there are many items to be treated, the usage condition can be considered that there are many items to be treated on the surface of the stove, which need to be treated.

[0113] In a preferred embodiment, in step S221 above, when the object to be treated is oil, the water flow status of the inlet and outlet of the stove 1 is controlled according to the usage, including:

[0114] When the proportion of oil on the water film surface is greater than the first preset value, or the number of oil particles is greater than the second preset value, the water flow rate at the inlet and outlet is increased.

[0115] When the proportion or quantity of oil stains exceeds the corresponding preset value, it indicates that the surface of the stove needs to be cleaned. By increasing the water flow rate at the inlet and outlet, the water flow rate can be increased instantaneously, causing the oil stains to flow to the outlet and be discharged outside the working area of ​​the stove surface. Specifically, after cooking begins, when the proportion of oil stains on the water film surface (a) is greater than a' or the number of oil stains (b) is greater than b', the flow rates Q1 and Q2 are increased, and the water flow velocity V1 also increases accordingly. When a and b return to less than or equal to the default values, the flow rates Q1 and Q2 are restored to their default values.

[0116] In a preferred embodiment, in step S222 above, when the object to be processed is a foreign object, the water flow state of the inlet and outlet of the stove 1 is controlled according to the usage, including:

[0117] When a foreign object is detected, the water flow rate at the inlet is increased within a first preset time to create a turbulent water flow.

[0118] After the impact is completed, foreign objects in the image information are detected again;

[0119] The water flow status of the inlet and outlet of the stove 1 is controlled based on the test results of the retest.

[0120] When a foreign object is detected, the water flow rate at the inlet is increased within a first preset time, thereby creating an impact water flow that moves the foreign object and prevents it from settling in a certain location, which would cause dirt to accumulate there.

[0121] Furthermore, based on the results of the re-test, the water flow status of the inlet and outlet of the stove 1 is controlled, including:

[0122] If a foreign object is detected to have moved a preset distance, the water inlet and outlet of the stove 1 will be controlled to maintain their initial state.

[0123] If the detected foreign object remains stationary, the foreign object information is recorded and synchronized to the user's device.

[0124] If movement of a foreign object is detected, it can prevent the object from remaining in one position for an extended period of time; if no movement of the foreign object is detected, feedback is sent to the user for decision-making.

[0125] In practice, when a large foreign object (area S, type k) is detected, the flow rate Q1 is immediately increased by 30% (example value, calculation function F1(S, k)) for 3 seconds (example value, calculation function F2(S, k)), then the original flow rate is restored, creating a powerful water jet to flush the foreign object away a certain distance. This prevents stains from settling due to prolonged stillness at high temperatures. If the foreign object is not flushed away, its information is recorded. This record is synchronized to the user's mobile device, where they can annotate it, indicating whether they agree to increase the flow rate or that the identified object is not a foreign object. If the user agrees to increase the flow rate, the flow rate will be increased in both magnitude and duration the next time the object is detected during cooking; otherwise, the original flow rate will remain unchanged. If the user believes the identified object is not a foreign object, the image recognition model is adjusted, and the next time the same object is matched, no large foreign object scenario processing will be applied.

[0126] In a preferred embodiment, step S200 above, determining the usage condition of the stove surface based on image information and / or sound information, further includes:

[0127] Based on image and / or sound information, and based on cooking actions and / or sounds within the working area of ​​the cooktop surface, determine the usage status of the cooktop surface.

[0128] Furthermore, step S300 above includes:

[0129] When the cooking action is identified as a stir-fry action and / or the cooking sound is a stir-fry sound, increase the water flow rate at the inlet and outlet.

[0130] When the cooking action is identified as an overflow action and / or the cooking sound is an overflow sound, increase the water flow rate at the inlet and outlet.

[0131] In practice, if both the stir-frying action c (0: no, 1: yes) and the stir-frying sound e (0: no, 1: yes) are present, it is considered to meet the stir-frying scenario, and the flow rate Q1 and Q2 are increased by 10% (example value); if both the overflowing situation d (0: no, 1: yes) and the overflowing sound f (0: no, 1: yes) are present, it is considered to meet the overflowing scenario, and the flow rate Q1 and Q2 are increased by 20% (example value).

[0132] Furthermore, the cleaning method also includes: recording whether the user actively intervenes to adjust the water pump flow rate in each stir-frying and overflowing scenario, such as increasing or decreasing the flow rate; when the same intervention is performed more than 3 times in a row (example value), such as decreasing the flow rate three times in a row, the flow rate increase for the corresponding scenario will be adjusted in the same way, such as adjusting the 10% increase in the stir-frying scenario to 8%.

[0133] In addition, the recognition of special scenarios will be pushed to the user's mobile phone when new scenarios are supported. The user can choose whether to use the special scenario function and load the corresponding training model into the device.

[0134] In a preferred embodiment, in step S100 above, the infrared temperature measurement and image recognition camera 520 disposed above the surface of the stove detects the image information of the surface of the stove; and the sound recognition sensor 510 disposed around the stove 1 detects the sound information of the stove 1.

[0135] The infrared temperature measurement and image recognition camera 520 improves detection accuracy, more precisely distinguishing the properties of the materials to be processed within the work area, thereby forming corresponding water flow patterns for effective cleaning. The sound recognition sensor 510, either alone or in combination with image recognition, enhances the accuracy of judging the cooking status.

[0136] As a preferred embodiment, the cleaning method further includes: after cooking is completed, controlling the height of the grate at the drain outlet to be lowered below the surface of the cooktop in order to drain the water from the surface of the cooktop.

[0137] After cooking is complete, drain the remaining water from the cooktop 1 by pressing the stop button on the water inlet height adjustment motor 410 or manually lowering the water outlet height H4 to 0 or lower. Allow any remaining water on the cooktop 1 to air dry naturally or wipe it dry with a cloth.

[0138] The present invention also provides a cleaning device for the surface of a cooktop, the cleaning device comprising:

[0139] The first module is used to acquire image and / or sound information within the working area on the surface of the stove;

[0140] The second module is used to determine the condition of the stove surface based on image and / or sound information;

[0141] The third module is used to control the water flow status of the inlet and outlet of the stove 1 according to the usage situation, wherein the inlet and outlet are located at the two ends of the stove surface along its length direction L1.
