[0047] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0048] The oil cup of the traditional range hood is usually arranged on the range hood in a detachable manner. When the waste oil in the oil cup accumulates to a certain amount, the user needs to manually detach the oil cup from the range hood for cleaning. The whole cleaning process is very cumbersome, and when the user does not clean in time, it is easy to cause excessive accumulation of oil to overflow and pollute the cooking environment.

[0049] Based on this, as Figure 1 shown, in the embodiment, an oil cup cleaning device 100 is provided, which comprises an oil amount detection assembly 101, an oil cup cleaning assembly 102, and a controller 103 connected with the oil amount detection assembly 101 and the oil cup cleaning assembly 102.

[0050] The oil amount detection assembly 101 is a detection assembly for detecting the oil accumulation in the oil cup to obtain oil amount detection data. The oil amount detection assembly 101 can detect the oil accumulation in the oil cup in response to an oil amount detection event. The oil amount detection event can be that the range hood is in a running state, or the user triggers an oil amount detection instruction based on the oil accumulation detection requirement. It can be understood that the oil amount detection assembly 101 can be any detection device capable of detecting oil accumulation, such as an image acquisition device, an infrared sensing device, a weight sensing device, a liquid level detection device, etc. Different types of oil amount detection assemblies 101 correspond to different setting positions.

[0051] In some embodiments, the oil amount detection assembly 101 can be an infrared sensing device. The infrared sensing device can be arranged above the oil cup. When the oil amount detection event is triggered, the infrared sensing device emits an infrared signal to the waste oil surface in the oil cup. The time of sending the infrared signal and receiving the reflected infrared signal is the oil amount detection data. Subsequently, the controller can determine the liquid level of the waste oil in the oil cup according to the time length of receiving the reflected infrared signal, and further determine the oil accumulation of the oil cup.

[0052] In some embodiments, the oil amount detection assembly 101 can be a weight sensing device. The weight sensing device can be arranged at the gravity center position of the bottom of the oil cup. When the oil amount detection event is triggered, the weight sensing device can record the oil amount detection data according to the change of the weight of the oil cup. The controller determines the oil accumulation of the oil cup according to the change record of the weight of the oil cup.

[0053] The oil cup cleaning assembly 102 is a cleaning assembly for automatically cleaning the oil cup. It can be constructed by multiple cleaning components according to actual cleaning requirements. The oil cup cleaning assembly 102 is controlled by the controller 103 and can effectively clean the oil cup to different degrees.

[0054] The controller 103 is connected to both the oil level detection component 101 and the oil cup cleaning component 102. Based on the oil level detection component 101, it acquires oil level detection data from the oil cup. When the oil level detection data determines that the oil cup meets the initial cleaning conditions, it acquires historical cleaning data for the oil cup. The initial cleaning conditions include the amount of oil collected in the oil cup. If, based on the historical cleaning data, the historical cleaning data determines that the oil cup meets the deep cleaning conditions, it controls the oil cup cleaning component 102 to perform deep cleaning of the oil cup. The deep cleaning conditions include the degree of oil buildup in the oil cup.

[0055] The aforementioned oil cup cleaning device detects the oil level in the oil cup using an oil level detection component. This provides oil level data reflecting the current oil level in the cup. The controller then accurately assesses the oil level based on this data, determines the appropriate cleaning method to meet the actual oil level, and controls the oil cup cleaning component to automatically clean the cup, thereby improving the convenience of oil cup cleaning.

[0056] Furthermore, such as Figure 2 As shown, in some embodiments, a range hood 200 is provided, which includes a range hood body 201 and an oil cup cleaning device 202 as described in the above embodiments. When the range hood 200 is running, the oil cup cleaning device 202 can clean the oil cup, thereby improving the user experience by increasing the convenience of oil cup cleaning.

[0057] Based on the same inventive concept, this application also provides a self-cleaning control method for an oil cup applied to the above-mentioned oil cup cleaning device.

[0058] In some embodiments, such as Figure 3 As shown, a self-cleaning control method for an oil cup is provided, which can be applied to... Figure 1 Taking controller 103 as an example, the following steps are included:

[0059] S302, Obtain oil level detection data from the oil cup.

[0060] The oil cup detection data refers to the data obtained by the oil level detection component in detecting the amount of oil collected in the oil cup. This data indicates the oil collection status within the oil cup. Understandably, the specific content of the oil cup detection data is related to the type of the oil cup detection component. For example, if the oil cup detection component is an image acquisition device, then the oil cup detection data is the image obtained after the image acquisition device captures an image of the oil cup. If the oil cup detection component is an infrared sensor device, then the oil cup detection data is the time data of the infrared signal sent and received by the infrared sensor device.

[0061] Specifically, when the oil amount detection event is triggered, the oil amount detection component in the oil cup cleaning device detects the collected oil amount in the oil cup to obtain oil amount detection data, and sends the oil amount detection data to the controller. The controller obtains the oil amount detection data of the oil cup.

[0062] S304, when the oil cup meets the preliminary cleaning condition according to the oil amount detection data, obtaining the historical cleaning data of the oil cup, the preliminary cleaning condition including the collected oil amount of the oil cup.

[0063] The preliminary cleaning condition is a preset condition for determining whether the oil cup needs to be preliminarily cleaned, and the preliminary cleaning condition includes a condition determined based on the collected oil amount of the oil cup. When the oil cup meets the preliminary cleaning condition, it means that the collected oil amount of the oil cup has reached the standard for preliminary cleaning, and the oil cup needs to be preliminarily cleaned. When the oil cup does not meet the preliminary cleaning condition, it means that the collected oil amount in the oil cup at this time has not reached the preliminary cleaning standard, and there is still a certain capacity space to continue to store the waste oil separated by the range hood.

[0064] In some embodiments, the preliminary cleaning condition is that the collected oil amount of the oil cup is greater than a preset collected oil threshold. Specifically, after the controller obtains the oil amount detection data, it determines the collected oil amount of the oil cup at the time of the oil amount detection according to the oil amount detection data, and compares the collected oil amount of the oil cup with the preset collected oil threshold. If the collected oil amount of the oil cup is greater than or equal to the preset collected oil threshold, it can be determined that the oil cup meets the preliminary cleaning condition and needs to be preliminarily cleaned. The preset collected oil threshold is a cleaning threshold determined by the designer according to the actual capacity of the oil cup in advance. If the collected oil amount in the oil cup reaches the preset collected oil threshold, the oil cup needs to be cleaned, otherwise it will likely cause the waste oil in the oil cup to overflow and pollute the user's cooking environment.

[0065] The historical cleaning data refers to the cleaning data recorded when the oil cup is cleaned last time, and the historical cleaning data can include the time of the last oil cup self-cleaning, the duration of the self-cleaning, and some specific operation parameters when the oil cup is self-cleaned. The controller can determine the cleaning condition of the oil cup self-cleaning according to the historical cleaning data.

[0066] Specifically, the controller determines the collected oil amount of the oil cup according to the oil amount detection data, determines whether the oil cup meets the preliminary cleaning condition based on the collected oil amount of the oil cup, and obtains the historical cleaning data of the oil cup when the collected oil amount of the oil cup meets the preliminary cleaning condition.

[0067] S306, in the case where the oil cup meets the deep cleaning condition based on the historical cleaning data, controlling the oil cup to perform deep cleaning, the deep cleaning condition including a condition determined based on the oil cup cleaning interval.

[0068] The deep cleaning condition is a preset condition for determining whether the oil cup needs to be deep cleaned, and the deep cleaning condition includes a condition determined based on the cleaning interval of the oil cup. When the oil cup meets the deep cleaning condition, it means that the cleaning frequency of the oil cup is high, that is, the collectable oil amount of the oil cup is reduced, and a large amount of oil dirt may be accumulated in the oil cup, so the oil cup needs to be deep cleaned to improve the collectable oil amount of the oil cup.

[0069] Specifically, the controller determines the cleaning condition of the oil cup for self-cleaning according to the historical cleaning data, and determines whether the oil cup meets the deep cleaning condition according to the cleaning condition of the oil cup for self-cleaning. If yes, a deep cleaning control instruction is generated and sent to the oil cup cleaning assembly. The oil cup cleaning assembly performs deep cleaning on the oil cup in response to the deep cleaning control instruction.

[0070] In some embodiments, the controller controls the oil cup to perform deep cleaning, which can be in the form of hot water flushing. Specifically, heated cleaning water is injected into the oil cup to dissolve the accumulated waste oil and oil dirt in the oil cup, and then the oil-water mixture is discharged from the oil cup.

[0071] In some embodiments, the controller controls the oil cup to perform deep cleaning, which can be in the form of oil removal agent cleaning. Specifically, the controller injects an oil removal agent into the oil cup from a preset oil removal agent storage area, and then injects a preset amount of cleaning water into the oil cup. After waiting for a preset time, the oil removal agent fully reacts with the waste oil and oil dirt in the oil cup, and then the mixed liquid in the oil cup is discharged from the oil cup.

[0072] The above oil cup self-cleaning control method obtains oil amount detection data of the oil cup, which can reflect the current oil collection amount of the oil cup. When it is determined according to the oil amount detection data that the oil cup meets the preliminary cleaning condition, it is further determined according to the historical cleaning data of the oil cup whether the oil cup meets the deep cleaning condition. The deep cleaning condition includes a condition determined based on the cleaning interval of the oil cup. If the oil cup meets the deep cleaning condition, it means that the cleaning frequency of the oil cup increases, that is, the collectable oil amount of the oil cup is reduced, and a large amount of oil dirt may be accumulated in the oil cup, so the oil cup needs to be deep cleaned to improve the collectable oil amount of the oil cup. The controller directly controls the oil cup to automatically perform deep cleaning without the need for the user to manually disassemble the oil cup for cleaning. By determining the cleaning mode that meets the actual oil collection condition of the oil cup through different cleaning conditions, the oil cup is automatically cleaned, and the convenience of oil cup cleaning is improved.

[0073] In some other embodiments, the oil cup self-cleaning control method further includes: controlling the oil cup to perform preliminary cleaning in a case where it is determined based on the historical cleaning data that the oil cup does not meet the deep cleaning condition.

[0074] Specifically, the controller determines the cleaning condition of the oil cup for self-cleaning according to historical cleaning data. If it is determined that the oil cup does not meet the deep cleaning condition based on the cleaning condition of the oil cup for self-cleaning, it indicates that the cleaning frequency of the oil cup has not increased, and there is still enough oil collection space in the oil cup, so that the oil cup does not need to be deep cleaned temporarily, and only needs to be preliminarily cleaned to clean the waste oil currently stored in the oil cup. The controller generates a preliminary cleaning control instruction and sends the preliminary cleaning control instruction to the oil cup cleaning assembly. The oil cup cleaning assembly responds to the preliminary cleaning control instruction to preliminarily clean the oil cup. By preliminarily cleaning the oil cup, the situation that the waste oil in the oil cup overflows and pollutes the user's cooking environment can be effectively avoided.

[0075] Further, the oil cup cleaning assembly can preliminarily clean the oil cup in the following manner.

[0076] In some embodiments, the control of the preliminary cleaning of the oil cup comprises:

[0077] The waste oil in the oil cup is heated to obtain temperature detection data of the waste oil in the heating process. When it is determined according to the temperature detection data that the temperature of the waste oil reaches a preset temperature threshold, the heated waste oil is discharged from the oil cup.

[0078] In which, since the waste oil accumulated in the oil cup generally contains a large amount of impurities, has complex composition, high viscosity and poor flowability, in order to quickly discharge the waste oil accumulated in the oil cup from the oil cup and complete the preliminary cleaning of the oil cup, the waste oil in the oil cup can be heated to improve the flowability of the waste oil, so that the waste oil can be smoothly discharged from the oil cup.

[0079] The preset temperature threshold is a preset threshold for judging whether the flowability of the waste oil can reach the discharge standard. The preset temperature threshold is a temperature threshold determined by the designer in advance according to the capacity of the accumulated waste oil in the oil cup that meets the preliminary cleaning condition and the heating temperature required to heat the waste oil of the capacity to a standard flow state. The designer stores the preset temperature threshold in the storage area of the controller so that the controller can access it at any time.

[0080] Specifically, in combination with the oil cup cleaning device shown in Figure 1 The oil cup cleaning assembly can further include a heating assembly, a temperature detection assembly, and a valve arranged at the outlet of the oil cup, and the controller is connected with the heating assembly, the temperature detection assembly, and the valve, respectively.

[0081] The heating assembly can be used to heat the waste oil in the oil cup to provide heat energy for the waste oil to enhance the flowability of the waste oil. The heating assembly can be a heating pipe, an electromagnetic heater, etc. The setting position and the number of the heating assembly are not limited in the present application, as long as the oil cup can be uniformly heated.

[0082] The bottom of the oil cup is provided with an outlet for discharging the waste oil or other cleaning generated liquid accumulated in the oil cup. In order to better realize the oil collecting function of the oil cup, the closing and opening of the oil cup outlet is controlled by a valve arranged at the oil cup outlet. When the valve is in the on state, the oil cup outlet is in the open state, and the waste oil or other cleaning generated liquid can be discharged from the oil cup through the oil cup outlet. When the valve is in the off state, the oil cup outlet is in the closed state, and the oil cup can continue to realize the waste oil storage function to receive the oil separated during the operation of the range hood. It can be understood that the valve arranged at the oil cup outlet can be an electromagnetic valve.

[0083] In some embodiments, the outlet of the oil cup can be connected with an oil discharge pipeline, the end of the oil discharge pipeline can be connected with a kitchen sink, and the waste oil or other cleaning generated liquid in the oil cup can enter the oil discharge pipeline through the oil cup outlet and finally flow into the kitchen sink, without affecting the normal cooking environment of the user.

[0084] The temperature detection assembly is a component for real-time monitoring of the temperature of the waste oil during heating. When the heating assembly heats the waste oil in the oil cup, the temperature detection assembly detects the temperature of the waste oil in real time to obtain temperature detection data. According to the temperature detection data, the controller can determine the change of the temperature of the waste oil in the oil cup. It can be understood that the temperature detection assembly can be any component capable of real-time monitoring of the temperature and collecting data, such as a temperature sensor, a temperature sensing bag, etc. The specific arrangement position and specific number of the temperature detection assembly are not limited in the present application, as long as the temperature of the waste oil in the oil cup can be accurately collected and recorded.

[0085] Specifically, when the controller determines that the oil cup needs to be preliminarily cleaned, it first generates a heating instruction and sends the heating instruction to the heating assembly. The heating assembly responds to the heating instruction to start heating the waste oil in the oil cup to increase the flowability of the waste oil. The controller simultaneously generates a temperature detection instruction and sends the temperature detection instruction to the temperature detection assembly. The temperature detection assembly responds to the temperature detection instruction to detect the temperature of the waste oil in the oil cup to obtain temperature detection data and feed back the temperature detection data to the controller.

[0086] The controller determines the real-time temperature of the waste oil in the heating process according to the received temperature detection data, and compares the temperature of the waste oil with a preset temperature threshold. When the temperature of the waste oil reaches the preset temperature threshold, it is determined that the waste oil reaches the preset standard flow state and can be better discharged from the oil cup. The controller generates a valve opening instruction and sends the valve opening instruction to the valve arranged at the oil cup outlet. The valve opens in response to the valve opening instruction to open the channel between the oil cup outlet and the oil discharge pipeline, discharges the waste oil in the standard flow state from the oil cup through the oil cup outlet, and completes the preliminary cleaning of the oil cup.

[0087] The above embodiment can increase the flowability of the waste oil in the oil cup by heating the waste oil. When the waste oil reaches a standard flow state, the waste oil is discharged from the oil cup, effectively increasing the cleaning effect of the preliminary cleaning of the oil cup, improving the convenience of the cleaning of the oil cup, and effectively improving the user experience.

[0088] Further, in order to improve the cleaning effect of the deep cleaning of the oil cup, in some embodiments, as shown in Figure 4 The control of the deep cleaning of the oil cup includes:

[0089] S402, control the oil cup to perform preliminary cleaning.

[0090] Specifically, the controller can control the oil cup to perform preliminary cleaning by the method of controlling the oil cup to perform preliminary cleaning in the above embodiment.

[0091] S404, when the preliminary cleaning of the oil cup is completed, a preset amount of cleaning water is injected into the oil cup to perform ultrasonic cleaning of the oil cup.

[0092] The content of the cleaning water is determined by the designer according to the actual volume of the oil cup in advance and is configured in the storage area of the controller. The cleaning water content corresponding to different volumes of the oil cup is also different. The preset amount of cleaning water can ensure the complete cleaning of the oil cup, and also will not overflow the oil cup due to ultrasonic vibration, causing pollution to the user's cooking environment. During ultrasonic cleaning, the preset amount of cleaning water can be used as a cleaning medium during ultrasonic cleaning. The ultrasonic energy drives the cleaning water to vibrate, thereby cleaning the oil stains accumulated in the oil cup.

[0093] Specifically, in combination with the oil cup cleaning device as shown in Figure 1 The oil cup cleaning assembly can further include a water pump, an ultrasonic assembly, and a valve arranged at the outlet of the oil cup, and the controller is connected with the water pump, the ultrasonic assembly, and the valve arranged at the outlet of the oil cup, respectively.

[0094] The water pump is used to provide power for the process of injecting the preset amount of cleaning water into the oil cup. One end of the water pump can be connected to a water inlet pipe, and the water inlet pipe can be connected to a preset water storage device. When it is necessary to inject cleaning water into the oil cup, the running water pump can provide power for the cleaning water, and the cleaning water is injected from the preset water storage device into the oil cup through the water inlet pipe. In some embodiments, the water pump can be a self-priming pump.

[0095] The ultrasonic assembly is an assembly for ultrasonic cleaning of the oil cup. The ultrasonic assembly can generate a specific cleaning frequency to drive the cleaning medium, i.e., clean water, to vibrate, thereby removing stubborn dirt in the oil cup. It can be understood that the specific position of the ultrasonic assembly is not limited in the present application, as long as it can generate a specific cleaning frequency and effectively clean the dirt in the oil cup through the cleaning medium. In some embodiments, the ultrasonic assembly can be an ultrasonic generator.

[0096] After the controller completes the initial cleaning of the oil cup, it continues to generate a water pump start instruction and sends the water pump start instruction to the water pump. The water pump starts to operate in response to the water pump start instruction and injects a preset amount of clean water into the oil cup through the water inlet pipe. The controller then generates an ultrasonic cleaning instruction and sends the ultrasonic cleaning instruction to the ultrasonic assembly. The ultrasonic assembly starts to generate a specific frequency in response to the ultrasonic cleaning instruction, drives the preset amount of clean water to vibrate, and performs ultrasonic cleaning of the dirt in the oil cup.

[0097] S406, after the ultrasonic cleaning is completed, the oil-water mixture in the oil cup is discharged from the oil cup.

[0098] Specifically, after the ultrasonic cleaning of the oil cup is completed, the liquid in the oil cup will be an oil-water mixture produced by ultrasonic dissolution of the dirt in the clean water. The controller generates a valve opening instruction and sends the valve opening instruction to the valve arranged at the outlet of the oil cup. The valve opens in response to the valve opening instruction, connects the outlet of the oil cup and the oil discharge pipe, discharges the oil-water mixture in the oil cup from the oil cup, and completes the deep cleaning of the oil cup.

[0099] In some embodiments, after the controller starts the ultrasonic cleaning of the oil cup by the ultrasonic assembly, it records the ultrasonic cleaning time of the oil cup in real time, compares the ultrasonic cleaning time with a preset cleaning time, and determines that the ultrasonic cleaning of the oil cup is completed when the ultrasonic cleaning time reaches the preset cleaning time. The preset cleaning time is a preset time parameter for judging whether the dirt in the oil cup is completely dissolved. The designer pre-generates the preset cleaning time according to the ultrasonic cleaning time required for the dirt in the oil cup to be completely dissolved, and stores the preset cleaning time in the storage area of the controller for the controller to call at any time.

[0100] In the above embodiments, on the basis of the initial cleaning of the oil cup, the further ultrasonic cleaning can effectively remove the dirt accumulated in the oil cup, effectively increase the cleaning effect of the self-cleaning of the oil cup, and improve the convenience of the cleaning of the oil cup.

[0101] Accurate judgment of whether the oil cup meets the deep cleaning condition is an important factor for improving the cleaning effect and convenience of the oil cup. The following describes several methods for accurately judging whether the oil cup meets the deep cleaning condition.

[0102] In some embodiments, the historical cleaning data comprises a time of a previous self-cleaning of the oil cup. The determining that the oil cup meets the deep cleaning condition based on the historical cleaning data comprises:

[0103] The interval cleaning time of the oil cup is determined based on the time of the previous self-cleaning of the oil cup and a current time. In a case where the interval cleaning time is less than a preset interval threshold, it is determined that the oil cup meets the deep cleaning condition.

[0104] The preset interval threshold is a time parameter for determining whether the oil cup meets the deep cleaning condition. A designer can determine the oil stain accumulation amount corresponding to the deep cleaning of the oil cup according to actual needs, and determine the preset interval threshold according to the time required for the oil collection amount in the oil cup to meet the preliminary cleaning condition from zero under the oil stain accumulation amount. In a case where the time interval between the time of the previous self-cleaning of the oil cup and the time of the current self-cleaning of the oil cup, i.e., the interval cleaning time, is less than the preset time interval value, it can be considered that the oil stain accumulation amount in the current oil cup has reached the standard requiring deep cleaning. The oil stain accumulation in the oil cup reduces the oil collection space of the oil cup and greatly reduces the oil collection amount. If not cleaned in time, the cleaning event of the oil cup will be triggered frequently, which increases the frequency of self-cleaning of the oil cup, wastes cleaning resources, and affects user experience. Therefore, the oil cup needs to be deep cleaned to improve the oil collection effect of the oil cup.

[0105] Specifically, the controller obtains the time of the previous self-cleaning of the oil cup according to the historical cleaning data, compares the time of the previous self-cleaning of the oil cup with a current time, i.e., the time of the current triggering of the self-cleaning of the oil cup, and determines the interval cleaning time of the oil cup. The controller calls the preset interval threshold, compares the interval cleaning time with the preset interval threshold, and in a case where the interval cleaning time is less than the preset interval threshold, determines that the oil cup meets the deep cleaning condition, and can control the oil cup to be deep cleaned.

[0106] In the above embodiments, by recording the time of the self-cleaning of the oil cup, the interval cleaning time of the current cleaning of the oil cup from the previous cleaning can be quickly determined, and by comparing the interval cleaning time with the preset interval threshold, it can be quickly determined whether the oil cup meets the deep cleaning condition, which effectively improves the accuracy of selecting the cleaning method of the oil cup, and further improves the cleaning effect and cleaning convenience of the oil cup.

[0107] In other embodiments, the historical cleaning data comprises historical temperature detection data obtained by detecting the temperature of the waste oil of the oil cup during the previous preliminary cleaning. The determining that the oil cup meets the deep cleaning condition based on the historical cleaning data further comprises:

[0108] If it is determined according to the historical temperature detection data that the preliminary cleaning is performed last time, the temperature change rate of the waste oil in the oil cup is obtained. When the temperature change rate is less than the preset temperature change rate, it is determined that the oil cup meets the deep cleaning condition.

[0109] The temperature change rate is a parameter for characterizing the temperature change of the waste oil in the heating process. The higher the temperature change rate, the faster the temperature change of the waste oil in the heating process can be considered. The lower the temperature change rate, the slower the temperature change of the waste oil in the heating process can be considered. Therefore, the amount of oil dirt accumulated in the oil cup can be determined according to the temperature change rate.

[0110] It can be understood that although most of the waste oil can be discharged from the oil cup each time the preliminary cleaning is performed, due to surface tension and other reasons, a certain amount of waste oil will remain on the cup wall and cup bottom of the oil cup. The remaining waste oil will become oil dirt attached to the oil cup under the action of air oxidation. When the oil dirt in the oil cup gradually increases, the oil dirt will absorb more heat to improve its own flowability during the heating process, so the temperature change rate of the waste oil during the heating process is slower. Conversely, when the oil dirt is less, the waste oil accumulated in the oil cup is itself of a certain flowability, and the temperature change rate of the waste oil during the heating process is faster.

[0111] The preset temperature change rate is a rate parameter for determining whether the oil cup meets the deep cleaning condition. The designer can determine the corresponding oil dirt accumulation amount required for the deep cleaning of the oil cup according to the actual needs, and obtain the temperature detection data of the waste oil collected during heating when the oil collection amount in the oil cup meets the preliminary cleaning condition under the oil dirt accumulation amount. The temperature change rate of the waste oil is calculated based on the temperature detection data, and the temperature change rate is determined as the preset temperature change rate. It can be understood that in actual use, when the temperature change rate of the waste oil during the heating process is greater than the preset temperature change rate, it can be considered that the oil dirt accumulation amount in the current oil cup has not reached the standard of deep cleaning, and the preliminary cleaning can also meet the user's use demand. When the temperature change rate of the waste oil during the heating process is less than the preset temperature change rate, it can be considered that the oil dirt accumulation amount in the current oil cup has reached the standard of deep cleaning. The oil dirt accumulation causes the oil collection space of the oil cup to decrease, and the oil collection amount decreases greatly. If it is not cleaned in time, the event of cleaning the oil cup will be triggered frequently, resulting in an increase in the self-cleaning frequency of the oil cup, which wastes cleaning resources and also affects the user experience. Therefore, the oil cup needs to be deep cleaned to improve the oil collection effect of the oil cup.

[0112] Specifically, the controller obtains historical temperature detection data of the waste oil of the oil cup obtained by temperature detection of the waste oil when preliminary cleaning of the oil cup was performed last time according to historical cleaning data, and obtains the temperature change rate of the waste oil during heating if it is determined that preliminary cleaning of the oil cup was performed last time according to the historical temperature detection data. The controller compares the temperature change rate with a preset temperature change rate, and determines that the oil cup meets the deep cleaning condition and can control the oil cup to perform deep cleaning when the temperature change rate of the waste oil is less than the preset temperature change rate.

[0113] In the above embodiment, the temperature change rate of the waste oil when the waste oil was heated last time can be quickly determined through the historical cleaning data, and whether the oil cup meets the deep cleaning condition can be quickly determined by comparing the temperature change rate with the preset temperature change rate, thereby effectively improving the accuracy of selecting the cleaning mode of the oil cup and further improving the cleaning effect and cleaning convenience of the oil cup.

[0114] In addition to the above two judgment methods, in some embodiments, in order to further improve the accuracy of judgment, the above two judgment methods can be used at the same time to judge whether the deep cleaning condition is met.

[0115] Specifically, the controller can obtain the time of the last oil cup self-cleaning according to historical cleaning data, and determine the cleaning interval time of the oil cup by comparing the time of the last oil cup self-cleaning with the current time. In the case that the cleaning interval time is less than the preset interval threshold, the controller obtains historical temperature detection data of the waste oil of the oil cup obtained by temperature detection of the waste oil when preliminary cleaning of the oil cup was performed last time according to historical cleaning data, and obtains the temperature change rate of the waste oil during heating if it is determined that preliminary cleaning of the oil cup was performed last time according to the historical temperature detection data. The temperature change rate is compared with a preset temperature change rate, and the oil cup is determined to meet the deep cleaning condition and can control the oil cup to perform deep cleaning when the temperature change rate of the waste oil is less than the preset temperature change rate.

[0116] Through the double judgment method in the above embodiment, even if the last cleaning time of the oil cup is a passive triggered cleaning time due to human operation or environmental factors, such as the recorded cleaning time of the oil cup cleaning caused by the user's automatic trigger of the forced cleaning operation, or the recorded cleaning time caused by the interruption of the power supply and other environmental factors. The judgment accuracy can also be further guaranteed by the judgment of the temperature change rate.

[0117] In order to further improve the intelligence of the oil cup cleaning and match the user's needs, in some embodiments, the oil cup is controlled to perform deep cleaning when the oil cup meets the deep cleaning condition based on the historical cleaning data, including:

[0118] In a case where it is determined based on the historical cleaning data that the oil cup meets the deep cleaning condition, a deep cleaning prompt information is generated and pushed, and the deep cleaning prompt information is used to prompt that the oil cup needs to be deep cleaned. In response to a deep cleaning instruction triggered based on the deep cleaning prompt information, the oil cup is controlled to be deep cleaned.

[0119] Specifically, in combination with the oil fume exhauster shown in the above embodiments, the oil fume exhauster can further include a prompt component connected with the controller. The prompt component is used to push prompt information to the user and prompt the user that the current oil cup needs to be cleaned. It can be understood that the prompt component of the oil fume exhauster can be any component capable of prompting the user, such as a voice broadcast component, a display component, a warning light, etc. Figure 2

[0120] In a case where it is determined based on the historical cleaning data that the oil cup meets the deep cleaning condition, the controller generates a deep cleaning prompt information and pushes the deep cleaning prompt information to the prompt component of the oil fume exhauster. The prompt component prompts the user with the received deep cleaning prompt information in a preset prompt manner. For example, when the prompt component is a voice broadcast component, the prompt information can be broadcast to the user through voice broadcast. When the prompt component is a display component, the deep cleaning prompt information can be directly displayed to the user. When the prompt component is a warning light, the user can be prompted in a preset flashing manner.

[0121] The user determines whether the oil cup needs to be deep cleaned based on the deep cleaning prompt information fed back by the prompt component according to actual needs. When the oil cup needs to be deep cleaned, a deep cleaning instruction can be triggered according to a preset triggering manner, such as triggering the generation of a deep cleaning instruction through a confirmation button provided on the oil fume exhauster, or triggering the generation of a deep cleaning instruction through a confirmation option displayed on the display component, etc. The controller responds to the deep cleaning instruction and controls the oil cup to be deep cleaned. When the user does not need to deep clean the oil cup, a no cleaning instruction can also be triggered according to a preset triggering manner. The controller responds to the no cleaning instruction and does not perform deep cleaning operation on the oil cup.

[0122] In some embodiments, the controller generates and pushes a deep prompt information according to the amount of oil collected in the oil cup when the oil cup meets the deep cleaning condition, which can effectively help the user to understand the current oil collection situation in the oil cup and provide data reference for the user's next selection.

[0123] In the above embodiments, in a case where the oil cup meets the deep cleaning condition, the deep cleaning prompt information is generated and pushed to the user, which can help the user to better understand the current oil collection situation in the oil cup and determine whether to perform oil cup self-cleaning according to the user's own needs, effectively improving the intelligence of oil cup cleaning and the matching degree with the user's needs. ​

[0124] In some embodiments, an oil cup self-cleaning control method is provided, which is applied to... Figure 5 The following explanation uses the range hood shown as an example.

[0125] like Figure 5 As shown, the range hood 500 includes a range hood body 501 and an oil cup cleaning assembly 502. The range hood body 501 is provided with a detachable oil cup 5011 and a display screen 5012.

[0126] Oil cup cleaning component 502 includes:

[0127] A gravity sensor 5021 is installed at the center of gravity of the bottom of the oil cup 5011. The gravity sensor 5021 is used to monitor and provide feedback on the oil collection volume data of the oil cup 5011 in real time.

[0128] The heating tube 5022 is located at the bottom of the oil cup 5011 and is used to heat the waste oil in the oil cup 5011.

[0129] A temperature sensor 5023 is installed on the side wall of the oil cup 5011. The temperature sensor 5023 is used to monitor the temperature of the waste oil in the oil cup 5011 during the heating process.

[0130] A solenoid valve 5024 is installed at the bottom of the oil cup 5011 and connected to the oil drain port. The solenoid valve 5024 is used to controllably open and close the oil drain port, thereby opening or closing the oil drain channel.

[0131] A self-priming water pump 5025 is installed at the water inlet of the oil cup. One end of the self-priming water pump 5025 is connected to the water inlet pipe and is used to inject cleaning water into the oil cup 5011.

[0132] An ultrasonic generator 5026, located at the bottom and side wall of the oil cup 5011, is used to generate ultrasonic waves of a specific frequency to perform ultrasonic cleaning on the oil cup 5011.

[0133] The controller 5027, which is connected to the gravity sensor 5021, heating tube 5022, temperature sensor 5023, solenoid valve 5024, self-priming water pump 5025 and ultrasonic generator 5026 respectively, is used to implement the following oil cup self-cleaning control method and control the oil cup cleaning component 502 to perform cleaning operations on the oil cup 5011.

[0134] Among them, such as Figure 6 As shown, the above-mentioned oil cup self-cleaning control method specifically includes the following steps:

[0135] First, when the range hood is powered on, the gravity sensor responds to the start-up event by monitoring the oil level in the oil cup in real time, obtaining the oil level detection data, and then feeding the oil level detection data back to the controller.

[0136] The controller determines the oil collection amount of the oil cup according to the oil amount detection data, compares the oil collection amount of the oil cup with a preset oil collection threshold, and if the oil collection amount of the oil cup is less than the preset oil collection threshold, returns to receiving the oil amount detection data fed back by the gravity sensor.

[0137] If the oil collection amount of the oil cup is greater than or equal to the preset oil collection threshold, it is determined that the oil cup meets the preliminary cleaning condition, and the controller obtains historical temperature detection data obtained by performing temperature detection on the waste oil in the oil cup during the last preliminary cleaning. According to the temperature detection data, the temperature change rate of the waste oil in the oil cup during heating is determined, and when the temperature change rate is greater than or equal to a preset temperature change rate, it is determined that the oil cup does not meet the deep cleaning condition, and the oil cup cleaning assembly is controlled to perform preliminary cleaning on the oil cup.

[0138] Specifically, the controller first generates a heating instruction, sends the heating instruction to the heating pipe, and the heating pipe responds to the heating instruction to start heating the waste oil in the oil cup to increase the flowability of the waste oil. The controller simultaneously generates a temperature detection instruction and sends the temperature detection instruction to the temperature sensor. The temperature sensor responds to the temperature detection instruction to detect the temperature of the waste oil in the oil cup and obtains temperature detection data, which is fed back to the controller. The controller determines the real-time temperature of the waste oil during heating according to the received temperature detection data, and compares the temperature of the waste oil with a preset temperature threshold. When the temperature of the waste oil reaches the preset temperature threshold, the controller generates a valve opening instruction and sends the valve opening instruction to the electromagnetic valve arranged at the oil cup oil outlet. The electromagnetic valve responds to the valve opening instruction to open and conduct the channel between the oil cup oil outlet and the oil discharge pipe, discharges the waste oil in the oil cup from the oil cup, and completes the preliminary cleaning of the oil cup.

[0139] When the temperature change rate is less than the preset temperature change rate, it is determined that the oil cup meets the deep cleaning condition, the controller generates a deep cleaning prompt information according to the oil collection amount in the current oil cup, and displays the deep cleaning prompt information to the user through the display screen, prompting the user that the oil cup needs to be deep cleaned. Based on the deep cleaning prompt information fed back by the display screen, the user can determine whether the oil cup needs to be deep cleaned according to the actual needs. When the oil cup does not need to be deep cleaned, the user can select the no cleaning option on the display screen to trigger the generation of a no cleaning instruction. The controller responds to the no cleaning instruction and does not perform deep cleaning operation on the oil cup, but only performs preliminary cleaning operation. When the oil cup needs to be deep cleaned, the user can select the cleaning option on the display screen to trigger the generation of a deep cleaning instruction, and the controller responds to the deep cleaning instruction to control the oil cup to perform deep cleaning.

[0140] Specifically, the controller first performs preliminary cleaning on the oil cup by the preliminary cleaning method, and on the basis of the preliminary cleaning, the controller continues to generate a water pump starting instruction, sends the water pump starting instruction to the self-priming water pump, and the self-priming water pump opens and runs in response to the water pump starting instruction, and then injects a preset amount of cleaning water into the oil cup through the water inlet pipe. The controller then generates an ultrasonic cleaning instruction, sends the ultrasonic cleaning instruction to the ultrasonic generator, and the ultrasonic generator starts to generate a specific frequency in response to the ultrasonic cleaning instruction, drives the preset amount of cleaning water to vibrate, and performs ultrasonic cleaning on the oil dirt in the oil cup. After completing the ultrasonic cleaning of the oil cup, the controller generates a valve opening instruction, and sends the valve opening instruction to the electromagnetic valve arranged at the oil discharge port of the oil cup. The electromagnetic valve opens in response to the valve opening instruction, and the channel between the oil discharge port of the oil cup and the oil discharge pipe is connected, so that the oil-water mixture in the oil cup is discharged from the oil cup, and the deep cleaning of the oil cup is completed.

[0141] It can be understood that in addition to being able to display prompt information, the oil collection amount of the oil cup monitored by the gravity sensor in real time can also be displayed on the display screen in a preset display form, such as displaying the remaining percentage of the oil cup capacity on the display screen, etc., to help the user better understand the oil collection situation of the oil cup.

[0142] In the above embodiments, by arranging the gravity sensor, the heating pipe, the temperature sensor, the electromagnetic valve, the self-priming water pump, the ultrasonic generator and the controller on the range hood, the problem of oil cup oil collection reminding and cleaning in daily life can be effectively solved. The intelligent detection reminding and self-cleaning technology reduces the cleaning cost, improves the experience of the user of the range hood, and brings convenience to people's life.

[0143] It should be understood that although each step in the flowchart involved in each of the above embodiments is displayed in sequence according to the arrow, these steps are not necessarily executed in sequence according to the arrow. Unless otherwise stated herein, the execution of these steps is not strictly limited in sequence, and these steps can be executed in other sequences. Moreover, at least part of the steps in the flowchart involved in each of the above embodiments can include multiple steps or stages, which are not necessarily executed at the same time, but can be executed at different times, and the execution sequence of these steps or stages is not necessarily sequential, but can be executed alternately or alternately with at least part of other steps or steps or stages in other steps.

[0144] Based on the same inventive concept, the embodiments of the present application also provide an oil cup self-cleaning control device for implementing the oil cup self-cleaning control method described above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme described in the above method, and therefore the specific limitations in one or more oil cup self-cleaning control device embodiments provided below can refer to the limitations of the oil cup self-cleaning control method described above, which will not be repeated here.

[0145] In some embodiments, as shown in Figure 7 An oil cup self-cleaning control device 700 is provided, comprising a data acquisition module 701, a preliminary cleaning judgment module 702, and a deep cleaning module 703, wherein:

[0146] The data acquisition module 701 is configured to acquire oil amount detection data of the oil cup.

[0147] The preliminary cleaning judgment module 702 is configured to, when it is determined according to the oil amount detection data that the oil cup meets a preliminary cleaning condition, acquire historical cleaning data of the oil cup, the preliminary cleaning condition comprising a condition determined based on the oil collection amount of the oil cup.

[0148] The deep cleaning module 703 is configured to, in a case where it is determined based on the historical cleaning data that the oil cup meets a deep cleaning condition, control the oil cup to perform deep cleaning, the deep cleaning condition comprising a condition determined based on a cleaning interval of the oil cup.

[0149] The oil cup self-cleaning control device described above acquires oil amount detection data of the oil cup, which can reflect the current oil collection amount of the oil cup. When it is determined according to the oil amount detection data that the oil cup meets a preliminary cleaning condition, it is further determined according to the historical cleaning data of the oil cup whether the oil cup meets a deep cleaning condition, the deep cleaning condition comprising a condition determined based on a cleaning interval of the oil cup. If the oil cup meets the deep cleaning condition, it means that the cleaning frequency of the oil cup is increased, i.e., the collectable oil amount of the oil cup is reduced, and a large amount of oil dirt may be accumulated in the oil cup, so that the oil cup needs to be cleaned deeply to increase the collectable oil amount of the oil cup. The controller directly controls the oil cup to automatically perform deep cleaning without the need for the user to manually disassemble the oil cup for cleaning. By judging different cleaning conditions, a cleaning method that meets the actual oil collection condition of the oil cup is determined, and the oil cup is automatically cleaned, thereby improving the convenience of oil cup cleaning.

The deep cleaning module is further configured to: determine a temperature change rate of the waste oil in the oil cup when the preliminary cleaning is performed last time according to the historical temperature detection data; and when the temperature change rate is less than a preset temperature change rate, determine that the oil cup meets the deep cleaning condition.

[0155] In some embodiments, the deep cleaning module is further configured to: when it is determined that the oil cup meets the deep cleaning condition based on the historical cleaning data, generate and push a deep cleaning prompt information, the deep cleaning prompt information being used to prompt that the oil cup needs to be deep cleaned; and in response to a deep cleaning instruction triggered based on the deep cleaning prompt information, control the oil cup to perform deep cleaning.
