Description

Technical Field

[0001] The present application relates to the technical field of fruit and vegetable cleaning equipment, and particularly to a cleaning device and a household appliance. Background Art

[0002] During the growth process of fruits and vegetables in the fields, they will come into contact with many mold spores, such as soil, irrigation water, gray mold spores and penicillium spores in the air, etc. These spores will lurk on the surface of fruits and vegetables. After the fruits and vegetables are picked, their resistance decreases, and when the temperature and humidity conditions are suitable during storage, they will grow and reproduce in large numbers, resulting in the rotting and mildewing of fruits and vegetables. In addition, most fruits and vegetables are harvested in high-temperature seasons, and the temperature of the fruits themselves is very high, and the respiratory heat is very large. Even in a cold storage with a relatively low temperature, it is not easy to reduce the fruit temperature, which accelerates the loss of moisture and the consumption of organic substances, and is not conducive to long-term storage.

[0003] In the prior art, cleaning after picking fruits and vegetables can remove impurities and microorganisms, and improve the cleanliness of the fruit and vegetable surface; pre-cooling can quickly remove field heat, delay the consumption of nutrients in fruits and vegetables, and extend the storage period. However, each type of fruit and vegetable has a different tolerance to cleaning pressure. Excessive cleaning pressure is likely to damage the surface of fruits and vegetables, while too little cleaning pressure will result in incomplete cleaning. The existing cleaning devices cannot adjust the cleaning pressure according to different types of fruits and vegetables, and are likely to damage the surface of fruits and vegetables or fail to clean properly.

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0047] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0048] For ease of description, spatially relative terms may be used herein to describe the relative positional relationship or movement of one element or feature shown in the figure with respect to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", "front", "rear", etc. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip, attitude change, or change in motion state, then these directional indications will change accordingly. For example, an element described as "below" or "beneath" another element or feature will subsequently be oriented as "above" or "over" the other element or feature. Thus, the exemplary term "below" can include both upward and downward orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative descriptors used herein are interpreted accordingly.

[0049] In the prior art, cleaning after fruit and vegetable picking can remove impurities and microorganisms and improve the cleanliness of the fruit and vegetable surface; pre-cooling can quickly remove field heat, delay the consumption of nutrients in fruits and vegetables, and extend the storage period. However, each type of fruit and vegetable has a different tolerance to cleaning pressure. Excessive cleaning pressure is likely to damage the fruit and vegetable surface, while too little cleaning pressure will result in incomplete cleaning. Existing cleaning devices cannot adjust the cleaning pressure for different types of fruits and vegetables, easily damaging the fruit and vegetable surface or failing to clean properly.

[0050] Among them, the surfaces of fruits and vegetables such as lychees, broccoli, and waxberries are uneven and prone to dirt accumulation. Traditional soaking and cleaning are difficult to clean them thoroughly. Among existing cleaning technologies, ultrasonic cleaning devices are suitable for cleaning fruits and vegetables with irregular shapes and non-smooth surfaces. Its principle is to use ultrasonic cavitation to generate cavitation bubbles. The cavitation bubbles contain high-pressure gas, and when they collapse instantaneously, they generate high temperature and high pressure on the liquid medium, thereby generating a huge shear force and a large number of free radicals. The micro-jet flow and free radicals brought by the shear force can remove stains on the surface of fruits and vegetables, degrade some agricultural residues, inactivate enzymes to inhibit the browning of fruits and vegetables, and reduce the number of microorganisms, etc. However, each type of fruit and vegetable has a different tolerance to ultrasonic power. Excessive ultrasonic power is likely to damage the surface of fruits and vegetables, and too little ultrasonic power cannot clean them thoroughly. Existing ultrasonic cleaning devices cannot adjust the ultrasonic power according to different fruits and vegetables, which is likely to damage the surface of fruits and vegetables or fail to clean them properly.

[0051] As Figures 1 to 3 shown, the present application provides a cleaning device, including a cleaning chamber 1, a cleaning basket 2, and a spraying assembly 3. The cleaning chamber 1 is provided with a partition 11, and a first door 12 is arranged on the partition 11. The partition 11 divides the cleaning chamber 1 into a temporary storage space 101 and a cleaning space 102. The temporary storage space 101 is used to store fruits and vegetables to be cleaned of a preset type; the cleaning basket 2 is arranged in the cleaning space 102. The cleaning basket 2 includes a track 21, and one end of the track 21 is connected to the first door 12; the spraying assembly 3 is arranged in the cleaning space 102 and is used to spray clean water on the fruits and vegetables in the cleaning space 102; among them, when the cleaning device identifies the preset type of fruits and vegetables, the first door 12 is controlled to open, and the fruits and vegetables enter the cleaning space 102 from the first door 12, and the spraying assembly 3 adjusts the spraying pressure and / or spraying time according to the preset type of fruits and vegetables to clean the fruits and vegetables in the cleaning space 102.

[0052] It can be understood that after the fruits and vegetables are picked, the fresh fruits and vegetables to be cleaned are placed in the temporary storage space 101. After identifying the preset type of fruits and vegetables, the first door 12 is controlled to open, and the fruits and vegetables sequentially enter the cleaning space 102 from the first door 12 and slowly rotate and roll down along the track 21 under the action of their own gravity. At the same time, the spraying assembly 3 adjusts the spraying pressure and spraying time according to the preset type of fruits and vegetables. The spraying assembly 3 sprays water mist with a certain pressure (which can be clean water) on the fruits and vegetables to wash away impurities and dirt such as residual leaves and sludge on the surface of the fruits and vegetables. The fruits and vegetables can be cleaned while rotating, so that the fruits and vegetables are cleaned 360° all-round. By adjusting the spraying pressure and spraying time, it is possible to avoid damaging the surface of the fruits and vegetables due to excessive spraying pressure, and at the same time ensure that the fruits and vegetables are cleaned properly.

[0053] For example, fruits and vegetables without peels and husks such as strawberries, waxberries, and mulberries have the smallest corresponding spraying pressure because their surfaces are the most vulnerable; fruits and vegetables with skins such as grapes, cherry tomatoes, and potatoes have a medium corresponding spraying pressure because their surfaces are relatively vulnerable; fruits and vegetables with husks such as lychees, longans, and mangosteens have a relatively harder surface, and their corresponding spraying pressure can be set to be higher than that of the above two types of fruits and vegetables. Since the spraying pressure is the main influencing factor for damage to the surfaces of fruits and vegetables, the spraying pressure is mainly adjusted for different types of fruits and vegetables. Of course, the spraying time for different types of fruits and vegetables can also be set accordingly by themselves. For example, the spraying time for fruits and vegetables without peels and husks is shorter, and the spraying time for fruits and vegetables with husks is longer. The specific control parameters can be referred to Table 1 below.

[0054] Table 1. Spraying program control parameter table of the spraying component 3

[0055]

[0056] It should be noted that the user can set the spraying pressure and spraying time of the above different types of fruits and vegetables by themselves. The cleaning device can be provided with an interactive control panel, and the interactive control panel can adopt existing push-button displays or touch displays, etc. The user can change it through the parameter setting program of the interactive control panel. The specific working principle can be referred to the existing technology and will not be elaborated here.

[0057] In one example, as Figure 1 shown, the temporary storage space 101 and the cleaning space 102 are arranged side by side in the vertical direction. The temporary storage space 101 is arranged above the cleaning space 102, and the height of the temporary storage space 101 is less than the height of the cleaning space 102, so that the cleaning space 102 can store more fruits and vegetables, thereby improving the cleaning efficiency.

[0058] Optionally, a fourth door body 13 is provided at the top of the cleaning chamber 1. By opening the fourth door body 13, the fruits and vegetables to be cleaned can be put into the temporary storage space 101 from the fourth door body 13.

[0059] In some embodiments, as Figure 4 shown, the cleaning basket 2 includes an inner basket 22 and an outer basket 23. The cleaning chamber 1 is sleeved on the outer peripheral side of the outer basket 23, and the outer basket 23 is sleeved on the outer peripheral side of the inner basket 22. The track 21 is arranged between the outer basket 23 and the inner basket 22, and one end of the track 21 away from the first door body 12 spirally descends around the inner basket 22. One side of the track 21 close to the inner basket 22 is welded to the inner basket 22, and one side of the track 21 close to the outer basket 23 is welded to the outer basket 23. The inner basket 22 and the outer basket 23 are used to limit the movement range of the fruits and vegetables to prevent the fruits and vegetables from falling and being damaged. The fruits and vegetables slowly rotate and roll down along the spiral track 21 under the action of their own gravity, which can prevent the fruits and vegetables from being stacked and not cleaned properly.

[0060] Specifically, the track 21 is set as a spiral track 21, that is, the track 21 is set as a spiral surface with the central axis of the inner basket 22 as the axis. The central axis of the inner basket 22 can be the Z axis shown in the figure, so that the trajectory of the fruits and vegetables rolling along the track 21 is a spiral curve. The spiral curve can be set as a cylindrical spiral or a conical spiral. In one example, the spiral curve is set as a cylindrical spiral for easy manufacture and use of the track 21.

[0061] Optionally, the bottom of the track 21 is provided with a hollowed-out part to prevent water accumulation at the bottom of the track 21 after cleaning.

[0062] Optionally, as Figure 3 shown, the temporary storage space 101 and the cleaning space 102 are arranged side by side in the vertical direction. An image detection unit 14 is provided at one end of the temporary storage space 101 away from the cleaning space 102. The image detection unit 14 is used to acquire images of the fruits and vegetables to be cleaned.

[0063] The image detection unit 14 can adopt a camera in the prior art to capture images of the fruits and vegetables to be cleaned. The image detection unit 14 can also include a matching module connected to the camera. The matching module stores a trained model, and matches the images of the fruits and vegetables to be cleaned with the model of the matching module to identify the preset types of the fruits and vegetables. The training and recognition processes of the foregoing images can refer to the existing image recognition and matching technologies and will not be elaborated here.

[0064] In some embodiments, as Figure 2 and Figure 3 shown, the spraying assembly 3 includes a nozzle 31 and a water pump 32. The cleaning chamber 1 is provided with an inner side wall 15 ( Figure 5 shown in the figure) at the cleaning space 102. The nozzle 31 is provided on the inner side wall 15 of the cleaning chamber 1. The output end of the water pump 32 is connected to the nozzle 31 to supply clean water to the nozzle 31.

[0065] The water pump 32 is connected to an external water supply system. After detecting and identifying the preset types of the fruits and vegetables, the water pump 32 supplies clean water to the nozzle 31. The nozzle 31 sprays water mist with a certain pressure into the cleaning space 102 onto the fruits and vegetables. The water mist cleans the fruits and vegetables through the first opening of the outer basket 23, thereby cleaning the dirt and impurities on the surface of the fruits and vegetables.

[0066] In one example, as Figure 5 shown, a plurality of nozzles 31 are provided. The plurality of nozzles 31 can be evenly distributed on the inner side wall 15 of the cleaning chamber 1 to avoid cleaning dead corners. The fruits and vegetables roll and are cleaned in the spiral track 21 to improve the cleaning uniformity of the fruits and vegetables.

[0067] Furthermore, as Figure 2As shown, the spraying assembly 3 includes an air pump 33 and an air inlet pipe 34. The first end of the air inlet pipe 34 is connected to the air pump 33, and the second end of the air inlet pipe 34 is connected to the nozzle 31.

[0068] The air pump 33 provides high-pressure airflows with different pressures to the air inlet pipe 34, so that the spraying pressure of the water mist of the nozzle 31 is adjustable, thereby adjusting different spraying pressures according to different types of fruits and vegetables, avoiding damage to the surfaces of fruits and vegetables, and ensuring the quality of fruits and vegetables. Of course, different spraying air pressures can also be formed by adjusting the opening size of the nozzle 31, thereby adjusting the water mist pressure.

[0069] In the prior art, different fruits and vegetables have different tolerances to ultrasonic waves. If the ultrasonic power is too high and the treatment time is too long, the fruit and vegetable cells will be damaged. If the ultrasonic power is too small and the treatment time is short, the cleaning will be incomplete.

[0070] In some embodiments, as Figure 2 and Figure 3 shown, it includes an ultrasonic cleaning assembly 4. The ultrasonic cleaning assembly 4 includes an ultrasonic cleaner 41, a water inlet pipe 42, and a water outlet pipe 43. The ultrasonic cleaner 41 is arranged in the cleaning space 102, and the ultrasonic cleaner 41 adjusts its ultrasonic power and working time according to the preset type of fruits and vegetables; the first end of the water inlet pipe 42 is communicated with the water pump 32, and the second end of the water inlet pipe 42 is communicated with the cleaning space 102; the first end of the water outlet pipe 43 is communicated with the cleaning space 102, and the second end of the water outlet pipe 43 is communicated with the external space. A first control valve 431 is arranged on the water outlet pipe 43.

[0071] The principle of the ultrasonic cleaner 41 is to use ultrasonic cavitation to generate cavitation bubbles. The cavitation bubbles contain high-pressure gas, and when they collapse instantaneously, they generate high temperature and high pressure on the liquid medium, and then generate a huge shear force and a large number of free radicals. The micro-jet flow and free radicals brought by the shear force can remove the stains on the surfaces of fruits and vegetables, degrade some agricultural residues, inactivate enzymes, inhibit the browning of fruits and vegetables, reduce the number of microorganisms, etc. After the spraying and cleaning is completed, clean water enters the cleaning space 102 of the cleaning chamber 1 through the water inlet pipe 42 and fills the cleaning space 102, and the water pump 32 stops working. Then, control the ultrasonic cleaner 41 to adjust its ultrasonic power and ultrasonic time according to the preset type of fruits and vegetables, and use the micro-jet flow and free radicals brought by the shear force generated by the cavitation bubbles to remove the stains on the surfaces of fruits and vegetables, degrade some agricultural residues, inactivate enzymes, inhibit the browning of fruits and vegetables, reduce the number of microorganisms, etc. Adjust the ultrasonic pressure and working time according to different types of fruits and vegetables, which can ensure that the fruits and vegetables are cleaned cleanly and will not damage the fruit and vegetable cells at the same time. When the ultrasonic cleaning is completed, control the first control valve 431 to open, and the clean water mixed with impurities and dirt leaves the cleaning space 102 through the water outlet pipe 43.

[0072] For example, fruits and vegetables without fruit peels and husks such as strawberries, waxberries, and mulberries have the weakest surfaces, so their corresponding ultrasonic power is the lowest and the ultrasonic working time is the shortest; fruits and vegetables with skins such as grapes, cherry tomatoes, and potatoes have relatively fragile surfaces, so their corresponding ultrasonic power is set to medium; fruits and vegetables with husks such as lychees, longans, and mangosteens have relatively hard surfaces, so their corresponding ultrasonic power can be set to be higher than that of the above two types of fruits and vegetables, and the corresponding ultrasonic working time is the longest. The specific control parameters can be referred to Table 2 below.

[0073] Table 2. Ultrasonic program control parameter table of the ultrasonic cleaner 41

[0074]

[0075] In the prior art, ultrasonic waves are reflected by the parallel inner walls of the cleaning tank to form standing waves (two waves with the same frequency and opposite transmission directions), resulting in uneven cleaning.

[0076] Further, as shown in Figure 5 and Figure 7 , the cleaning chamber 1 is set to have an irregular inner layer, and a plurality of inner side walls 15 of the cleaning chamber 1 are provided. The plurality of inner side walls 15 are connected in sequence. Among them, the widths of any two adjacent inner side walls 15 are different, and / or the included angles between any two adjacent inner side walls 15 are different, that is, the cross-section of the cleaning chamber 1 is a non-regular polygon. Through the above design, the mutually parallel inner side walls 15 can be minimized, thereby reducing the formation of ultrasonic standing waves, avoiding uneven ultrasonic cleaning effects, and avoiding dead corners in fruit and vegetable cleaning.

[0077] In some embodiments, as shown in Figure 5 , it includes a position sensor 16. The position sensor 16 is disposed on the inner side wall 15 of the cleaning chamber 1. Specifically, the position sensor 16 should be disposed above the inner side wall 15 of the cleaning chamber 1. The position sensor 16 is used to monitor the highest position of the fruits and vegetables on the track 21 or the highest water level in the cleaning space 102.

[0078] In an example, the position sensor 16 is used to monitor the highest position of the fruits and vegetables on the track 21. When the fruits and vegetables enter the cleaning space 102 from the temporary storage space 101, they will roll down along the track 21. If the position sensor 16 monitors that there are fruits and vegetables staying at the highest position on the track 21, it means that the track 21 is full. At this time, the first door 12 and the second door 242 are controlled to close.

[0079] In an example, the position sensor 16 is used to monitor the highest water level in the cleaning space 102. In the ultrasonic cleaning program, if the water pump 32 fills the cleaning space 102 with clean water, and at this time the position sensor 16 detects that the clean water reaches the highest water level, then the water pump 32 is controlled to stop.

[0080] In the prior art, after the fruits and vegetables are washed, if there is too much liquid water adhering to the surface of the fruits and vegetables, they are prone to rot and deterioration during storage. Therefore, the present application also designs a driving component 5 to drive the cleaning basket 2 to rotate, and uses centrifugal force to control the humidity of the washed fruits and vegetables. The specific design is described as follows.

[0081] In some embodiments, as Figure 4 shown, the cleaning device further includes a driving component 5. The driving component 5 includes a motor 51. The motor 51 is arranged on the partition plate 11. The top of the motor 51 is fixed below the temporary storage space 101 of the cleaning chamber 1. A rotor 52 is arranged at the power output end of the motor 51. The rotor 52 is detachably connected to the inner basket 22.

[0082] It should be noted that a speed reducer is arranged inside the motor 51. By driving the rotor 52 to rotate through the motor 51, the inner basket 22, the outer basket 23 and the track 21 are driven to rotate at a low speed together. The excess liquid water adhering to the surface of the fruits and vegetables is separated by centrifugal force, so as to avoid the fruits and vegetables from rotting and mildewing due to water accumulation during long-term storage.

[0083] Specifically, the motor 51 adjusts its output speed according to the preset type of the fruits and vegetables, so as to avoid damage to the surface of the fruits and vegetables due to too fast speed, thereby ensuring the quality of the fruits and vegetables. For example, fruits and vegetables without peel and shell such as strawberries, bayberries, and mulberries have the smallest corresponding speed because their surfaces are the most fragile; fruits and vegetables with peel such as grapes, cherry tomatoes, and potatoes have a medium corresponding speed because their surfaces are relatively fragile; fruits and vegetables with shells such as lychees, longans, and mangosteens have a relatively larger corresponding speed because their surfaces are relatively hard. Of course, the dehydration time of different types of fruits and vegetables can also be set accordingly. For example, the dehydration time of fruits and vegetables without peel and shell is shorter, and the dehydration time of fruits and vegetables with shells is longer. The specific control parameters can refer to Table 3 below.

[0084] Table 3. Control parameter table of the dehydration program of the driving component 5

[0085]

[0086] It should be noted that the above spraying, ultrasonic cleaning, dehydration and other procedures can be selected by the user according to the actual situation. You can choose any one of the procedures, or two of the procedures, or the spraying, ultrasonic cleaning, and dehydration procedures are carried out in sequence.

[0087] In some embodiments, as Figure 6 shown, the cleaning basket 2 includes a cover plate 24. One ends of the inner basket 22 and the outer basket 23 close to the partition plate 11 are both connected to the cover plate 24. Optionally, the connection method can be welding connection to improve the overall structural strength of the cleaning basket 2. A groove 241 is arranged on the cover plate 24. The rotor 52 is embedded in the groove 241 and is connected to the groove 241 in a snap-fit manner.

[0088] During installation, the rotor 52 is docked with the groove 241 so that the rotor 52 is connected to the cleaning basket 2, thereby transmitting the power of the motor 51. The rotor 52 of the motor 51 rotates, directly driving the entire cleaning basket 2 to rotate, so that the fruits and vegetables can shake off the excess liquid water under the action of centrifugal force.

[0089] The inner basket 22, the outer basket 23, the track 21 and the cover plate 24 are of an integral structure, and the cleaning basket 2 can be replaced and disassembled according to the size and type of the fruits and vegetables. The user is reminded to judge and replace by himself in the instruction manual of this cleaning device.

[0090] Further, the cleaning basket 2 includes an infrared locator. A second door body 242 corresponding to the first door body 12 is provided on the cover plate 24. The transmitting end of the infrared locator is provided on the first door body 12, and the receiving end of the infrared locator is provided on the second door body 242. The infrared locator is electrically connected to the motor 51 so that the first door body 12 and the second door body 242 are aligned in the vertical direction.

[0091] The transmitting end of the infrared locator is used to emit infrared signals. If the receiving end of the infrared locator does not receive infrared signals, it means that the first door body 12 and the second door body 242 are not aligned. At this time, the motor 51 is controlled to drive the entire cleaning basket 2 to rotate so that the first door body 12 and the second door body 242 are aligned in the vertical direction, and the fruits and vegetables can enter the cleaning space 102 after passing through the first door body 12 and the second door body 242 in sequence. Similarly, if the type of the fruits and vegetables is recognized, the first door body 12 and the second door body 242 are controlled to open simultaneously. The first door body 12 and the second door body 242 can adopt automatic doors in the prior art, and the space sizes occupied by the first door body 12 and the second door body 242 are similar, so as to pass fruits and vegetables of a compliant size and ensure the normal operation of the device.

[0092] In some embodiments, both the inner basket 22 and the outer basket 23 include transverse bars and longitudinal bars that intersect each other. A plurality of first openings are formed between the transverse bars and the longitudinal bars, and the water of the spraying assembly 3 passes through the first openings.

[0093] The transverse bars can be set as circular bars. For the convenience of manufacturing and use, the radii of the transverse bars of the inner basket 22 are equal, and the radii of the transverse bars of the outer basket 23 are equal. The intersecting parts of the transverse bars and the longitudinal bars are welded together to enhance the overall structural strength of the cleaning basket 2. The water of the spraying assembly 3 passes through the first openings, and the hollow design of the cleaning basket 2 does not block the spraying and ultrasonic cleaning of the fruits and vegetables.

[0094] In some embodiments, such as Figure 5As shown, a second opening is provided on the partition 11. The second opening communicates with the temporary storage space 101 and the cleaning space 102. A second control valve 112 is provided on the second opening, and the second control valve 112 is used to control the opening and closing of the second opening. A pressure sensor is provided on the inner side wall 15 of the cleaning chamber 1, and the pressure sensor is used to monitor the air pressure in the cleaning space 102.

[0095] By controlling the opening and closing of the second opening through the second control valve 112, the air pressure in the cleaning space 102 can be adjusted during the spraying process to prevent the air pressure in the cleaning space 102 from being too high. If the air pressure in the cleaning space 102 is too high, the second control valve 112 is controlled to open for pressure relief, thereby ensuring the safety of the cleaning device.

[0096] Furthermore, as Figure 3 shown, an inclined surface 111 is provided on the side of the partition 11 facing away from the cleaning space 102. The inclined surface 111 is inclined relative to the horizontal plane to have a high end and a low end, and the low end of the inclined surface 111 is connected to the first door body 12. Fruits and vegetables can roll down along the inclined surface 111 towards the first door body 12 under the action of their own gravity and enter the cleaning space 102 from the temporary storage space 101, avoiding the accumulation of fruits and vegetables in the temporary storage space 101.

[0097] In some embodiments, as Figure 3 shown, the cleaning device includes a precooling chamber 6. The precooling chamber 6 is arranged side by side with the cleaning chamber 1 in the vertical direction. The precooling chamber 6 is arranged at one end of the cleaning chamber 1 close to the cleaning space 102, and the precooling chamber 6 is provided with a third door body 61 communicating with the cleaning space 102.

[0098] Specifically, the third door body 61 can adopt an existing automatic door. The precooling chamber 6 is arranged below the cleaning chamber 1. After the fruits and vegetables are cleaned and surface dehydrated, the third door body 61 is controlled to open so that the fruits and vegetables enter the precooling chamber 6 from the cleaning space 102. The precooling chamber 6 is used for precooling the fruits and vegetables after cleaning, thereby extending the storage time of the fruits and vegetables.

[0099] Optionally, as Figure 1 shown, a fifth door body 62 is provided on the front surface (the side facing the user) of the precooling chamber 6. The user can open the fifth door body 62 to take out the processed fruits and vegetables.

[0100] Furthermore, as Figure 3 shown, a refrigeration component 67 is provided on one side of the precooling chamber 6. The precooling chamber 6 is provided with an air outlet 63 and an air return port 64 connected to the refrigeration component 67, and the refrigeration component 67 is used to provide cold air to the precooling chamber 6.

[0101] The refrigeration component 67 can adopt existing refrigeration devices such as compressors and heat exchangers. The working principle of the refrigeration device can refer to the prior art and will not be elaborated here. A blower is configured on the heat exchanger, and the blower is communicated with the air outlet 63 to supply cold air to the air outlet 63. The cold air enters the precooling chamber 6 from the air outlet 63 and then leaves from the air return port 64, thereby reducing the temperature in the precooling chamber 6, cooling the fruits and vegetables, and extending the storage time of the fruits and vegetables.

[0102] Further, a buffer layer 66 is arranged in the precooling chamber 6, and the buffer layer 66 is arranged on the side of the precooling chamber 6 away from the cleaning space 102.

[0103] The buffer layer 66 can be made of a flexible material and is arranged at the bottom of the precooling chamber 6. When the fruits and vegetables enter the precooling chamber 6 from the cleaning chamber 1, the buffer layer 66 plays a buffering role to prevent the fruits and vegetables from being damaged.

[0104] Of course, the buffer layer can be arranged on the inner side of the precooling chamber 6 to further prevent the fruits and vegetables from being damaged.

[0105] Further, an atomizer 65 and a humidity sensor are arranged inside the precooling chamber 6. The atomizer 65 is used to prepare water mist, and the humidity sensor is used to detect the humidity H of the precooling chamber 6. If the humidity of the precooling chamber 6 is lower than the first humidity threshold Hm1, then control the atomizer 65 to open, and the atomizer 65 supplies water mist to the precooling chamber 6 to increase the humidity of the precooling chamber 6; if the humidity of the precooling chamber 6 is higher than the second humidity threshold Hm2, then control the atomizer 65 to close, where the first humidity threshold is less than the second humidity threshold.

[0106] In one example, the target humidity range of the precooling chamber 6 is [80%, 90%]. If H < 80%, then control the atomizer 65 to open; if H > 90%, then control the atomizer 65 to close.

[0107] Further, a temperature sensor is arranged inside the precooling chamber 6. The humidity sensor is used to detect the temperature T of the precooling chamber 6. If the temperature of the precooling chamber 6 is higher than the first temperature threshold Tm1, then control the refrigeration component 67 to open, and the refrigeration component 67 supplies cold air to the precooling chamber 6 to reduce the temperature of the precooling chamber 6; if the temperature of the precooling chamber 6 is lower than the second temperature threshold Tm2, then control the refrigeration component 67 to close, where the second temperature threshold is less than the first temperature threshold.

[0108] In one example, the target temperature range of the precooling chamber 6 is [2°C, 8°C]. If T > 8°C, then control the refrigeration component 67 to open; if T < 2°C, then control the refrigeration component 67 to close.

[0109] The embodiment of the present application also provides a household device, including the cleaning device as described above.

[0110] The spraying assembly 3 adjusts the spraying pressure and spraying time according to the preset type of fruits and vegetables. The spraying assembly 3 sprays water mist with a certain pressure on the fruits and vegetables to wash away impurities and dirt such as residual leaves and sludge on the surface of the fruits and vegetables. The fruits and vegetables can be washed while rotating, so that the fruits and vegetables are washed 360° all-round. By adjusting the spraying pressure and spraying time, it is possible to avoid damaging the surface of the fruits and vegetables due to excessive spraying pressure, and at the same time ensure that the fruits and vegetables are washed thoroughly.

[0114] Place the fruits and vegetables to be cleaned in the temporary storage space 101 of the cleaning chamber 1 of the household device. After identifying the preset type of fruits and vegetables, control the first door body 12 to open. The fruits and vegetables sequentially enter the cleaning space 102 from the first door body 12 and slowly rotate and roll along the track 21 under the action of their own gravity. At the same time, the spraying assembly 3 adjusts the spraying pressure and spraying time according to the preset type of fruits and vegetables. The spraying assembly 3 sprays water mist with a certain pressure on the fruits and vegetables to wash away impurities and dirt such as residual leaves and sludge on the surface of the fruits and vegetables.

[0119] S3. Control the spraying assembly 3 to stop, and adjust the ultrasonic power and / or working time of the ultrasonic cleaner 41 according to the preset type of fruits and vegetables.

[0120] The ultrasonic cleaner 41 adjusts its ultrasonic power and working time according to the preset type of fruits and vegetables, and uses the micro-jet flow and free radicals generated by the shear force of cavitation bubbles to remove stains on the surface of fruits and vegetables, degrade some agricultural residues, inactivate enzymes, inhibit the browning of fruits and vegetables, reduce the number of microorganisms, etc. By adjusting the ultrasonic pressure and working time according to different types of fruits and vegetables, the fruits and vegetables can be guaranteed to be cleaned, and the cells of the fruits and vegetables will not be damaged at the same time.

[0121] In some embodiments, after step S3, it further includes:

[0122] S4. Control the first control valve 431 to open so that the sewage passes through the water outlet pipe 43 and leaves the cleaning space 102.

[0123] S5. Adjust the output speed and / or working time of the motor 51 according to the preset type of fruits and vegetables.

[0124] The motor 51 adjusts its output speed according to the preset type of fruits and vegetables to avoid damaging the surface of the fruits and vegetables due to too fast speed, thereby ensuring the quality of the fruits and vegetables.

[0125] In some embodiments, after step S5, it further includes:

[0126] Detect the humidity of the precooling chamber 6;
