Description

TECHNICAL FIELD

[0001] The present application relates to a working method of a cleaning device, a storage medium and a cleaning device. BACKGROUND

[0002] For a Chinese kitchen, since the food materials are very rich, the demand for cleaning fruits and vegetables, fish and meat is very high. At present, there are some cleaning machines on the market for cleaning fruits and vegetables, fish and meat to reduce the labor intensity of users. For example, the Chinese patent application for invention with the publication number CN111588286A, the prior patent application of the applicant with the publication number CN119732601A, and the prior patent application with the publication number CN120061442A all disclose cleaning machines that can be used for cleaning food materials, and the cleaning machines are all provided with air pumps to supply air into the cleaning cavities during cleaning to form micro-nano bubbles. These bubbles can produce strong physical friction when they burst, forming bursting force and water flow impact force, which can better strip the dirt on the food materials. On this basis, these micro-nano bubbles can penetrate into the fine gaps on the surface of the object, and the cleaning is more thorough, and the damage to the food materials is small.

[0003] However, the air pump in the existing fruit and vegetable cleaning machine usually works at a fixed speed, and cannot be dynamically adjusted according to the number of target cleaning objects, the type of stains and the cleaning process, thereby existing the following problems: 1. Energy waste, light load still runs at high speed, and the power consumption is redundant; 2. Unstable cleaning effect, stubborn stains need higher speed and water flow impact force, and fixed speed may cause incomplete cleaning; and for fruits and vegetables that are easy to wash and break (such as strawberries and waxberries), the air pump speed cannot be deeply coupled with the cleaning objects and the cleaning stages; 3. Noise pollution, high-speed continuous operation produces high-decibel noise, affecting user experience.

[0004] In addition, the existing fruit and vegetable cleaning machine only has the function of cleaning food materials, and does not have the function of temporarily raising fresh food materials (fish, shrimp, etc.), and the function is single. Even if the fruit and vegetable cleaning machine is used for temporarily raising food materials, the user needs to place the feeding pump and adjust the working parameters of the feeding pump independently, and the survival rate of the food materials is low.

[0033] Figure 2 The exploded view of the cleaning device in the embodiment of the present application. DETAILED DESCRIPTION

[0034] The present application will be further described in detail below with reference to the embodiments of the drawings.

[0035] The present application relates to a cleaning device, and also relates to a working method of the cleaning device, and the cleaning device realizes cleaning and / or temporary cultivation of food based on the working method.

[0036] As Figure 2 shown, the cleaning device in the embodiment includes a cleaning tank 1, a supply system, a controller, and a memory.

[0037] The cleaning tank 11 is a tank body structure, which includes an upwardly open tank body, and a cover body is arranged on the tank body according to needs, and when the cover body is arranged, a closed cleaning tank 1 is formed, and when the cover body is not arranged, an open cleaning tank 1 is formed.

[0038] In the embodiment, the cleaning tank 1 can be installed in the water tank 6 for use, that is, the cleaning device further includes the water tank 6, and the cleaning tank 1 is installed in the water tank 6 in a fixed or detachable manner according to needs. In order to facilitate the cleaning tank 1 to be used independently as a container, and to facilitate the maximum use space of the water tank 6, the embodiment provides a cleaning tank 1 which can be combined with or separated from the water tank 6, and when the cleaning tank 1 is combined with the water tank 6, it is an electric cleaning tank 1, and when the cleaning tank 1 is separated from the water tank 6, it is restored to an independent large water tank 6, so as to meet different cleaning needs of users. The cleaning tank 1 is arranged in the water tank 6 in a transversely slidable manner. When the cleaning tank 1 moves to a fixed position, it is connected with the supply system to realize automatic cleaning and temporary cultivation of food materials. When the cleaning tank 1 moves to other positions, it is disconnected with the supply system, and the cleaning tank 1 can be taken out from the water tank 6 as an independent fruit and vegetable tank.

[0039] In order to save space, the supply system is arranged on the outer wall of the water tank 6, and then connected with the cleaning tank 1. The supply system in the embodiment can supply water and air to the cleaning tank 1, and also can realize the drainage of the cleaning tank 1.

[0040] The bottom of the cleaning tank 1 is provided with an air inlet connected with the supply system and a water passage. The supply system includes an air pump 2 for supplying air, an air inlet pipeline 3 connected with the air inlet, a water inlet pipeline 4 connected with the water passage, and a drainage pipeline 5, the water inlet pipeline 4 and the drainage pipeline 5 share one water passage, which can simplify the structure and facilitate production. The air pump 2 is connected with the inlet end of the air inlet pipeline 3. The inlet end of the water inlet pipeline 4 can be connected with a water pump to supply water to the cleaning tank 1 through the water inlet pipeline 4. When the supply system works, water and air can be supplied to the cleaning tank 1 at the same time, and then micro-nano bubbles are formed to realize better cleaning and temporary cultivation of food materials.

[0041] Based on the air pump 2, air can be supplied to the cleaning tank 1, and the air in the form of bubbles enters the water in the cleaning tank 1, and the oxygen in the bubbles can be released when the bubbles break, which is beneficial to maintain the water quality and meet the preservation requirements with oxygen demand. Therefore, the cleaning device in the embodiment can realize the temporary cultivation function of seafood and other food materials, and prolong the long-term freshness of the food materials. In order to facilitate the understanding of the oxygen concentration in the cleaning tank 1 during the temporary cultivation of food materials, an oxygen content sensor for detecting the oxygen concentration in the cleaning tank 1 is arranged in the cleaning tank 1, and the oxygen content sensor is electrically connected with a controller. During use, when the temporary cultivation of food materials is performed, the air pump 2 can be controlled according to the detected oxygen concentration to ensure that the oxygen concentration in the cleaning tank 1 is suitable for the temporary cultivation of food materials.

[0042] The controller in the supply system is electrically connected with the air pump 2, the memory and the oxygen content sensor, the controller can control the rotating speed of the air pump 2 and can also acquire the feedback rotating speed during the operation of the air pump 2. The memory stores computer instructions for enabling the controller to execute the working method of the cleaning device as follows.

[0043] As shown in Figure 1 the working method of the cleaning device in the embodiment is as follows: the cleaning device comprises multiple different working modes, and a corresponding air pump 2 rotating speed dynamic adjustment strategy is set for each working mode; during operation, the information of the selected working mode is acquired, the rotating speed of the air pump 2 is dynamically adjusted according to the air pump 2 rotating speed dynamic adjustment strategy corresponding to the current working mode, and then the work corresponding to the current working mode is completed.

[0044] When the rotating speed of the air pump 2 is dynamically adjusted, the air pump 2 needs to be adjusted from one rotating speed to another rotating speed, in order to avoid mechanical impact caused by large-span adjustment of the rotating speed of the air pump 2, when the rotating speed of the air pump 2 is adjusted, a gradual ramp speed adjustment algorithm is used to control the adjustment of the rotating speed of the air pump 2 from the current rotating speed to the to-be-adjusted rotating speed step by step.

[0045] Based on the air supply and water supply of the supply system to the cleaning tank 1, both the cleaning work of different food materials and the temporary cultivation work of seafood materials can be realized. When cleaning food materials, the demand for air supply is different based on the different characteristics of food materials, if cherry, raspberry, strawberry and other food materials in vegetables, the surface is fragile, and too large air bubble impact force is easy to wash and break, while apple, pear, grape, cucumber and other food materials have relatively high surface strength, and can be cleaned with higher air bubble impact force, but sweet potato, potato, peanut and other food materials have dirty surface, and ordinary air bubble impact force cannot effectively clean the dirt on the surface. In addition, fish, shrimp, shellfish and other seafood materials have different tolerances to air bubble impact force, therefore, in order to achieve better cleaning effect, the rotating speed of the air pump 2 needs to be dynamically adjusted according to different conditions to meet the demand for impact force at different moments of different food materials and cleaning process. When the food materials are temporarily cultivated, fish, shrimp and other seafood materials also have different demands for the oxygen content in water, and the rotating speed of the air pump 2 also needs to be adjusted adaptively.

[0046] Because of the foregoing different air supply demand, the cleaning device in the embodiment is provided with multiple different working modes, each of which can meet some demand close working conditions. The rotating speed adjustment of the air pump 2 can be targeted and adaptively solved for the air supply demand in different working modes.

[0047] The working method of the cleaning device in the embodiment sets multiple different working modes and their corresponding air pump 2 rotating speed dynamic adjustment strategies according to different working condition information, so that the formulated air pump 2 rotating speed dynamic adjustment strategy can solve specific problems in different working conditions.

[0048] The working condition information includes a function category and load characteristic data, and the function category includes a cleaning function and a temporary cultivation function.

[0049] When the function type is the cleaning function, the air pump 2 rotation speed dynamic adjustment strategy includes a cleaning time length, and the cleaning work is completed after the cleaning time length is reached. When the function type is the temporary cultivation function, the food placed in the cleaning tank 1 needs to be temporarily cultivated until the user selects to stop the cleaning device from working.

[0050] When the function type is the cleaning function, the load characteristic data includes a load category.

[0051] When the load category is fruits and vegetables, the load characteristic data further includes a fruit and vegetable hardness value and a surface pollution level. For example, cherry, waxberry and strawberry, which are easy to wash and rot, have a lower hardness value H of 100-200 and a lower surface pollution level of 1-2; apple, pear, grape and cucumber have a hardness value H of 300-400 and a surface pollution level of 3-4; sweet potato, potato and peanut, which have a relatively dirty surface, have a hardness value H of about 500 and a pollution level of 5. In order to achieve better cleaning effect, the number of cleaning paths and the cleaning time length of each cleaning work in the air pump 2 rotation speed dynamic adjustment strategy are set according to the fruit and vegetable hardness value and the surface pollution level. The sum of the cleaning time lengths of the cleaning works constitutes the cleaning time length in the air pump 2 rotation speed dynamic adjustment strategy.

[0052] When the load category is seafood, the load characteristic data further includes a dissolved oxygen demand and a pressure threshold. For example, fish and shrimp, which are relatively common seafood, have a relatively common dissolved oxygen demand and a pressure threshold; scallops, flower shell and snail, in order to ensure the survival rate during the cleaning process, have a relatively high dissolved oxygen demand, and the pressure threshold of the shells of these seafood is relatively high and difficult to clean. For example, the crustacean food requires a dissolved oxygen demand of ≥5 mg / L, and the shell of the shellfish has a pressure limit of <0.25 Mpa. In order to achieve better cleaning effect, the number of cleaning paths and the cleaning time length of each cleaning work in the air pump 2 rotation speed dynamic adjustment strategy are set according to the dissolved oxygen demand and the pressure threshold. Similarly, the sum of the cleaning time lengths of the cleaning works constitutes the cleaning time length in the air pump 2 rotation speed dynamic adjustment strategy.

[0053] When performing the cleaning work, after each cleaning work is completed, drainage is performed, and then the next cleaning work is performed. Whether to pause the cleaning work for a period of time between two cleaning works is determined according to the load characteristic data. Each cleaning work includes at least one cleaning stage in the three cleaning stages of pre-cleaning, deep cleaning and rinsing. The cleaning stages included in each cleaning work are determined according to the load characteristic data. For example, for the work mode corresponding to cleaning yams, potatoes, peanuts and the like, the first and second cleaning works both include pre-cleaning and deep cleaning, and the third cleaning work includes pre-cleaning, deep cleaning and rinsing. For the work mode corresponding to cleaning cherries, waxberries, strawberries and the like, the first, second and third cleaning works all include only deep cleaning and rinsing.

[0054] The air pump 2 speed adjustment range in the air pump 2 speed dynamic adjustment strategy is set according to the load characteristic data, that is, different air pump 2 speed adjustment ranges are set for different work modes corresponding to the load characteristic data. On the basis of the air pump 2 speed adjustment range, in the pre-cleaning stage, the air pump 2 is continuously operated based on high-frequency pulse control; in the deep cleaning stage, the air pump 2 is continuously operated based on medium-frequency pulse control; and in the rinsing stage, the air pump 2 is intermittently operated based on low-frequency pulse control. That is, the air pump 2 speed in the pre-cleaning stage is greater than the air pump 2 speed in the deep cleaning stage, and the air pump 2 speed in the deep cleaning stage is greater than the air pump 2 speed in the rinsing stage. The specific air pump 2 speed corresponding to each cleaning stage is set according to the air pump 2 speed adjustment range corresponding to the work mode, and the air pump 2 speed corresponding to the pre-cleaning stage, the deep cleaning stage and the rinsing stage is different in different work modes.

[0055] Based on the characteristics of different food materials, different food materials with different characteristics need to be treated differently when cleaning, that is, to meet the cleaning characteristics of food materials with different load characteristic data. Based on the cleaning function, the work modes specifically set in this embodiment include fruit and vegetable super-fast cleaning mode, fruit and vegetable daily cleaning mode, fruit and vegetable super-strong cleaning mode, seafood daily cleaning mode and seafood super-strong cleaning mode. The speed adjustment range in the air pump 2 speed dynamic adjustment strategy corresponding to each work mode is as follows. Fruit and vegetable super-fast cleaning mode: 1000RPM-19999RPM; fruit and vegetable daily cleaning mode: 10000RPM-19999RPM; fruit and vegetable super-strong cleaning mode: 20000RPM-40000RPM; seafood daily cleaning mode: 8000RPM-15000RPM; and seafood super-strong cleaning mode: 15000RPM-40000RPM.

[0056] In the fruit and vegetable super-fast cleaning mode, the fruit and vegetable daily cleaning mode, and the fruit and vegetable super-strong cleaning mode, in the pre-cleaning stage, based on the bubbles provided by the operation of the air pump 2, the surface silt is flushed by high-frequency pulse. In the deep cleaning stage, the air pump 2 continuously provides bubbles to clean the pesticide residues on the surface of the food. In the rinsing stage, the air pump 2 works intermittently, which can reduce the loss of nutrients of the food.

[0057] In the seafood daily cleaning mode and the seafood super-strong cleaning mode, in the pre-cleaning stage, based on the bubbles provided by the operation of the air pump 2, the surface silt and floating algae are flushed by high-frequency pulse. In the deep cleaning stage, the air pump 2 continuously provides bubbles to clean the mucus on the surface of the seafood. In the rinsing stage, the air pump 2 works intermittently, which reduces the damage to the food.

[0058] When the function category is the temporary cultivation function, the load characteristic data includes the temporary cultivation fresh food category and the oxygen demand, and then the air pump 2 speed adjustment range is set based on the load characteristic data. For example, for shrimp fry, adult shrimp, and fish, the corresponding air pump 2 speed adjustment ranges are as follows. Shrimp fry: 2500RPM-3000RPM; adult shrimp: shrimp fry: 4000RPM-5000RPM; fish: 6500RPM-7000RPM. Different and reasonable air pump 2 speed adjustment ranges are matched for different load characteristics, which can prolong the temporary cultivation time of the food,

[0059] For the working mode of the function category being the temporary cultivation function, the air pump 2 speed dynamic adjustment strategy is set as follows. Within the air pump 2 speed adjustment range, the air pump 2 is controlled to dynamically adjust the speed according to the set air pump 2 speed adjustment cycle. Within one air pump 2 speed adjustment cycle, the air pump 2 speed is gradually increased according to the first set time length as the time rhythm in the first half cycle time range, and the air pump 2 speed is gradually decreased according to the second set time length as the time rhythm in the second half cycle time range. In this embodiment, 1 hour is taken as the air pump 2 speed adjustment cycle, the air pump 2 speed is increased by 10% every 5 minutes in the first 30 minutes, and the air pump 2 speed is decreased by 10% every 5 minutes in the last 30 minutes.

[0060] In addition, for the working mode of the function category being the temporary cultivation function, the air pump 2 speed dynamic adjustment strategy can also be set as follows. The air pump 2 speed value in the evening time range is k times of the corresponding speed value in the daytime time range, 0

[0061] In order to maintain the water quality in the cleaning tank 1 to meet the survival of fresh food for a long time, for the working mode of the function category being the temporary cultivation function, when the temporary cultivation is performed, the water in the cleaning tank 1 is replaced according to the set water replacement cycle.

[0062] In addition, for the work mode of the temporary cultivation function, when the temporary cultivation work is carried out, the oxygen concentration in the cleaning tank 1 is detected in real time, and when the real-time oxygen concentration is less than the set oxygen supply requirement, the rotation speed of the air pump 2 is controlled according to the set oxygen supplement rotation speed control, until the oxygen concentration in the cleaning tank 1 reaches the set oxygen supply requirement. In this way, the lack of oxygen of the food can be avoided, and the death of the food due to lack of oxygen can be avoided, and the temporary cultivation time of the food is correspondingly prolonged.

[0063] The working method of the cleaning device in the application has multiple different working modes, and corresponding air pump 2 rotation speed dynamic adjustment strategies are set for each working mode. Different working modes can match different working conditions, so that the working mode corresponding condition can be adapted when the air pump 2 rotation speed is controlled, and the problems of energy consumption, working effect, noise and the like caused by fixed air pump 2 rotation speed are solved.

[0064] The cleaning device using the working method of the cleaning device has better working effect, is more intelligent and user-friendly, and improves the user experience.

[0065] The application also relates to a computer readable storage medium, which stores computer instructions for making a computer execute the working method of the cleaning device.
