[0002] Fruits and vegetables are exposed to many mold spores during their growth in the field, such as gray mold spores and penicillium spores in the soil, irrigation water, and air. These spores will lurk on the surface of fruits and vegetables. When the resistance of fruits and vegetables decreases after they are picked, and the temperature and humidity conditions are not suitable during storage, they will grow and reproduce in large quantities, causing the fruits and vegetables to rot and mold. In addition, most fruits and vegetables are harvested in high temperature seasons, the temperature of the fruit itself is very high, and the respiratory heat is very large. Even in a cold storage with a lower temperature, the fruit temperature is not easy to drop, which accelerates the loss of water and the consumption of organic matter, which is not conducive to long-term storage.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0049] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0050] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0051] In the prior art, washing fruits and vegetables after 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 fruit and vegetable nutrients, and extend the storage period. However, each type of fruit and vegetable has a different tolerance to washing pressure. Too high a washing pressure can easily damage the surface of the fruit and vegetable, while too low a washing pressure can cause incomplete washing. Existing washing devices cannot adjust the washing pressure for different types of fruits and vegetables, which can easily damage the surface of the fruit and vegetable or fail to clean them properly.

[0052] Among them, the surfaces of fruits and vegetables such as lychee, broccoli, and bayberry are uneven and easy to hide dirt, and traditional soaking and washing are difficult to clean. Among the existing cleaning technologies, ultrasonic cleaning devices are suitable for cleaning fruits and vegetables with irregular shapes and rough surfaces. The principle is to use ultrasonic cavitation to generate cavitation bubbles. The cavitation bubbles contain high-pressure gas, which collapses instantly to produce high temperature and high pressure on the liquid medium, thereby generating huge shear force and a large number of free radicals. The microjets and free radicals brought by the shear force can remove stains on the surface of fruits and vegetables, degrade some agricultural residues, passivate enzyme activity to inhibit browning of fruits and vegetables, and reduce the number of microorganisms. However, each type of fruit and vegetable has a different tolerance to ultrasonic power. Too much ultrasonic power can easily damage the surface of fruits and vegetables, and too little ultrasonic power can not be cleaned cleanly. The existing ultrasonic cleaning device cannot adjust the ultrasonic power for different fruits and vegetables, which can easily damage the surface of fruits and vegetables or fail to clean them properly.

[0053] like Figures 1 to 3 As shown, the present application provides a cleaning device, including a cleaning chamber 1, a cleaning basket 2 and a spray assembly 3. The cleaning chamber 1 is provided with a partition 11, and a first door body 12 is provided 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 preset types of fruits and vegetables to be cleaned; the cleaning basket 2 is arranged in the cleaning space 102, and the cleaning basket 2 includes a track 21, and one end of the track 21 is connected to the first door body 12; the spray 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; wherein, when the cleaning device recognizes the preset type of fruits and vegetables, the first door body 12 is controlled to open, and the fruits and vegetables enter the cleaning space 102 from the first door body 12, and the spray assembly 3 adjusts the spray pressure and / or spray time according to the preset type of fruits and vegetables to clean the fruits and vegetables in the cleaning space 102.

[0054] It is understandable that after picking the fruits and vegetables, 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 body 12 is controlled to open, and the fruits and vegetables enter the cleaning space 102 from the first door body 12 in sequence, and slowly rotate and roll along the track 21 under the action of the gravity of the fruits and vegetables themselves. At the same time, the spray component 3 adjusts the spray pressure and spray time according to the preset type of fruits and vegetables. The spray component 3 sprays water mist with a certain pressure (which can be clean water) on the fruits and vegetables to clean the impurities 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° in all directions. By adjusting the spray pressure and spray time, the surface of the fruits and vegetables is prevented from being damaged by excessive spray pressure, and at the same time, the fruits and vegetables are ensured to be cleaned in place.

[0055] For example, strawberries, bayberries, mulberries and other fruits and vegetables without peels and shells have the most fragile surfaces, so their corresponding spray pressure is the smallest; grapes, cherry tomatoes, potatoes and other fruits and vegetables with peels have a relatively fragile surface, so their corresponding spray pressure is set to medium; lychees, longans, mangosteens and other fruits and vegetables with shells have a relatively hard surface, so their corresponding spray pressure can be set to be larger than the above two types of fruits and vegetables. Since spray pressure is the main factor affecting the damage to the surface of fruits and vegetables, the spray pressure is mainly adjusted for different types of fruits and vegetables. Of course, the spray time of different types of fruits and vegetables can also be set accordingly. For example, the spray time of fruits and vegetables without peels and shells is shorter, and the spray time of fruits and vegetables with shells is longer. For specific control parameters, please refer to Table 1 below.

[0056] Table 1. Spray program control parameter table of spray component 3

[0057]

[0058] It should be noted that the user can set the spray pressure and spray time of the above-mentioned different types of fruits and vegetables by himself. The cleaning device can be provided with an interactive control panel. The interactive control panel can adopt an existing push-type display screen or a touch-type display screen, etc. The user can make changes through the parameter setting program of the interactive control panel. The specific working principle can refer to the existing technology and will not be elaborated here.

[0059] In one example, if Figure 1 As shown, the temporary storage space 101 and the cleaning space 102 are arranged side by side in the vertical direction, and the temporary storage space 101 is arranged above the cleaning space 102. The height of the temporary storage space 101 is smaller 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.

[0060] Optionally, a fourth door body 13 is provided on the top of the cleaning chamber 1 , and fruits and vegetables to be cleaned can be placed into the temporary storage space 101 through the fourth door body 13 by opening the fourth door body 13 .

[0061] In some embodiments, Figure 4 As shown, the washing basket 2 includes an inner basket 22 and an outer basket 23, the washing chamber 1 is sleeved on the outer peripheral side of the outer basket 23, 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 the end of the track 21 away from the first door body 12 spirally descends around the inner basket 22. The side of the track 21 close to the inner basket 22 is welded to the inner basket 22, and the 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 range of movement of 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 cleanly.

[0062] 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, and the central axis of the inner basket 22 can be the Z axis shown in the figure, so that the trajectory of fruits and vegetables rolling down the track 21 is a spiral curve, and the spiral curve can be set as a cylindrical spiral line or a conical spiral line. In one example, the spiral curve is set as a cylindrical spiral line, so that the track 21 is easy to manufacture and use.

[0063] Optionally, a hollow portion is provided at the bottom of the track 21 to prevent water from accumulating at the bottom of the track 21 after cleaning.

[0064] Alternatively, if Figure 3 As shown, the temporary storage space 101 and the cleaning space 102 are arranged side by side in the vertical direction, and an image detection unit 14 is provided at one end of the temporary storage space 101 away from the cleaning space 102, and the image detection unit 14 is used to obtain images of fruits and vegetables to be cleaned.

[0065] The image detection unit 14 can use 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, thereby identifying the preset types of fruits and vegetables. The training and recognition process of the aforementioned images can refer to the existing image recognition and matching technology, which will not be described in detail here.

[0066] In some embodiments, Figure 2 and Figure 3 As shown, the spray 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 As shown in FIG. 1 , the nozzle 31 is disposed on the inner wall 15 of the cleaning chamber 1 , and the output end of the water pump 32 is connected to the nozzle 31 to supply clean water to the nozzle 31 .

[0067] The water pump 32 is connected to the external water supply system. After detecting and identifying the preset type of fruits and vegetables, the water pump 32 supplies clean water to the nozzle 31. The nozzle 31 sprays water mist with a certain pressure to the fruits and vegetables in the cleaning space 102. The water mist cleans the fruits and vegetables through the first opening of the outer basket 23, thereby cleaning away the impurities and dirt on the surface of the fruits and vegetables.

[0068] In one example, if Figure 5 As shown, a plurality of nozzles 31 are provided, and the plurality of nozzles 31 can be evenly distributed on the inner wall 15 of the cleaning chamber 1 to avoid dead corners in cleaning. The fruits and vegetables are cleaned while rolling in the spiral track 21 to improve the cleaning uniformity of the fruits and vegetables.

[0069] Furthermore, if Figure 2As shown, the spray assembly 3 includes an air pump 33 and an air inlet pipe 34 , a first end of the air inlet pipe 34 is connected to the air pump 33 , and a second end of the air inlet pipe 34 is connected to the nozzle 31 .

[0070] The air pump 33 provides high-pressure airflows of different pressures to the air inlet pipe 34, so that the water mist spraying pressure of the nozzle 31 is adjustable, thereby adjusting different spraying pressures according to different types of fruits and vegetables, avoiding damage to the surface 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.

[0071] In the prior art, different fruits and vegetables have different tolerance to ultrasound. If the ultrasound power is too high or the treatment time is too long, the fruit and vegetable cells will be damaged. If the ultrasound power is too low or the treatment time is too short, it will cause incomplete cleaning.

[0072] In some embodiments, Figure 2 and Figure 3 As shown, it includes an ultrasonic cleaning component 4, which includes an ultrasonic cleaning device 41, an inlet pipe 42 and an outlet pipe 43. The ultrasonic cleaning device 41 is arranged in the cleaning space 102, and the ultrasonic cleaning device 41 adjusts its ultrasonic power and working time according to the preset type of fruits and vegetables; the first end of the inlet pipe 42 is connected to the water pump 32, and the second end of the inlet pipe 42 is connected to the cleaning space 102; the first end of the outlet pipe 43 is connected to the cleaning space 102, and the second end of the outlet pipe 43 is connected to the external space, and the outlet pipe 43 is provided with a first control valve 431.

[0073] The principle of the ultrasonic cleaning instrument 41 is to use ultrasonic cavitation to generate cavitation bubbles. The cavitation bubbles contain high-pressure gas, which collapses instantly to generate high temperature and high pressure on the liquid medium, thereby generating huge shear force and a large number of free radicals. The microjets and free radicals brought by the shear force can remove stains on the surface of fruits and vegetables, degrade some agricultural residues, passivate enzyme activity, inhibit browning of fruits and vegetables, reduce the number of microorganisms, etc. After the spray cleaning is completed, the 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 the ultrasonic cleaning instrument 41 is controlled to adjust its ultrasonic power and ultrasonic time according to the preset type of fruits and vegetables, and the microjets and free radicals brought by the shear force generated by the cavitation bubbles are used to remove stains on the surface of fruits and vegetables, degrade some agricultural residues, passivate enzyme activity, inhibit browning of fruits and vegetables, reduce the number of microorganisms, etc. The ultrasonic pressure and working time are adjusted according to different types of fruits and vegetables to ensure that the fruits and vegetables are cleaned without damaging the fruit and vegetable cells. When the ultrasonic cleaning is completed, the first control valve 431 is controlled to open, and the clean water mixed with impurities and dirt leaves the cleaning space 102 through the outlet pipe 43 .

[0074] For example, strawberries, bayberries, mulberries and other fruits and vegetables without peels and shells have the most fragile surface, so their corresponding ultrasonic power is the smallest and the ultrasonic working time is the shortest; grapes, cherry tomatoes, potatoes and other fruits and vegetables with skins have a relatively fragile surface, so their corresponding ultrasonic power is set to medium; litchi, longan, mangosteen and other fruits and vegetables with shells have a relatively hard surface, so their corresponding ultrasonic power can be set to be larger than the above two types of fruits and vegetables, and the corresponding ultrasonic working time is the longest. For specific control parameters, please refer to Table 2 below.

[0075] Table 2. Ultrasonic program control parameter table of ultrasonic cleaning instrument 41

[0076]

[0077] 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.

[0078] Furthermore, if Figure 5 and Figure 7 As shown, the cleaning chamber 1 is arranged as an irregular inner layer, and a plurality of inner side walls 15 are arranged in the cleaning chamber 1, and the plurality of inner side walls 15 are connected in sequence, wherein the widths of any two adjacent inner side walls 15 are different, and / or the 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 inner side walls 15 parallel to each other 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.

[0079] In some embodiments, Figure 5 As shown, it includes a position sensor 16, which is arranged on the inner wall 15 of the cleaning chamber 1. Specifically, the position sensor 16 should be arranged above the inner wall 15 of the cleaning chamber 1. The position sensor 16 is used to monitor the highest position of fruits and vegetables on the track 21 or the highest water level in the cleaning space 102.

[0080] In one example, the position sensor 16 is used to monitor the highest position of 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 detects that fruits and vegetables are staying at the highest position on the track 21, it means that the track 21 is fully loaded. At this time, the first door body 12 and the second door body 242 are controlled to be closed.

[0081] In one example, the position sensor 16 is used to monitor the maximum water level in the cleaning space 102. In the ultrasonic cleaning process, if the water pump 32 fills the cleaning space 102 with clean water, the position sensor 16 detects that the clean water reaches the maximum water level, and then controls the water pump 32 to stop.

[0082] In the prior art, after fruits and vegetables are washed, if there is too much liquid water attached to the surface of the fruits and vegetables, the fruits and vegetables are prone to rot and deterioration during storage. Therefore, the present application also designs a driving component 5 to drive the washing basket 2 to rotate and use centrifugal force to control the moisture of the washed fruits and vegetables. The specific design is described as follows.

[0083] In some embodiments, Figure 4 As shown, the cleaning device also includes a driving assembly 5, which includes a motor 51. The motor 51 is arranged on the partition 11, and the top of the motor 51 is fixed below the temporary storage space 101 of the cleaning chamber 1. The power output end of the motor 51 is provided with a rotor 52, and the rotor 52 is detachably connected to the inner basket 22.

[0084] It should be noted that a reducer is provided inside the motor 51. The motor 51 drives the rotor 52 to rotate, driving the inner basket 22, the outer basket 23 and the track 21 to rotate at a low speed, and the excess liquid water attached to the surface of the fruits and vegetables is separated by centrifugal force, so as to prevent the fruits and vegetables from rotting and mold due to water accumulation during long-term storage.

[0085] Specifically, the motor 51 adjusts its output speed according to the preset type of fruits and vegetables to avoid damage to the surface of fruits and vegetables due to excessive speed, thereby ensuring the quality of fruits and vegetables. For example, fruits and vegetables without peels and shells such as strawberries, bayberries, and mulberries have the smallest corresponding speeds because their surfaces are the most fragile; fruits and vegetables with skins such as grapes, cherry tomatoes, and potatoes have relatively fragile surfaces, so their corresponding speeds are set to medium; fruits and vegetables with shells such as lychees, longans, and mangosteens have relatively hard surfaces, so their corresponding speeds can be set to be larger than the above two types of fruits and vegetables. 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 peels and shells is shorter, and the dehydration time of fruits and vegetables with shells is longer. For specific control parameters, please refer to Table 3 below.

[0086] Table 3. Dehydration program control parameter table of drive assembly 5

[0087]

[0088] It should be noted that the user can select the above-mentioned spraying, ultrasonic cleaning, dehydration and other programs according to actual conditions. The user can select any one program, two of the programs, or perform the spraying, ultrasonic cleaning, dehydration programs in sequence.

[0089] In some embodiments, Figure 6 As shown, the cleaning basket 2 includes a cover plate 24, and the ends of the inner basket 22 and the outer basket 23 close to the partition 11 are connected to the cover plate 24. Optionally, the connection method can be welding to improve the overall structural strength of the cleaning basket 2. A groove 241 is provided on the cover plate 24, and the rotor 52 is embedded in the groove 241 and is snap-connected to the groove 241.

[0090] 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 cleaning basket 2 to rotate as a whole, so that the fruits and vegetables can shake off excess liquid water under the action of centrifugal force.

[0091] The inner basket 22, the outer basket 23, the track 21 and the cover plate 24 are an integrated structure, and the cleaning basket 2 can be replaced and disassembled according to the size and type of fruits and vegetables. The instructions for use of this cleaning device remind the user to make replacements at their own discretion.

[0092] Furthermore, the cleaning basket 2 includes an infrared locator, and a second door body 242 corresponding to the first door body 12 is arranged on the cover plate 24. The transmitting end of the infrared locator is arranged on the first door body 12, and the receiving end of the infrared locator is arranged 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.

[0093] The transmitting end of the infrared locator is used to transmit infrared signals. If the receiving end of the infrared locator does not receive the infrared signal, it means that the first door body 12 and the second door body 242 are not aligned. At this time, the control motor 51 drives the cleaning basket 2 to rotate as a whole, 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 pass through the first door body 12 and the second door body 242 in turn and enter the cleaning space 102. Similarly, if the type of fruits and vegetables is identified, the first door body 12 and the second door body 242 are controlled to open at the same time. The first door body 12 and the second door body 242 can use automatic doors in the prior art. The corresponding space occupied by the first door body 12 and the second door body 242 is similar in size, so that fruits and vegetables that meet the required size can pass through to ensure the normal operation of the device.

[0094] In some embodiments, both the inner basket 22 and the outer basket 23 include crisscrossing transverse bars and longitudinal bars, and a plurality of first openings are formed between the transverse bars and the longitudinal bars, and the first openings are used for water from the spray assembly 3 to pass through.

[0095] The transverse bars can be set as circular bars. For ease of manufacture and use, the radius of each transverse bar of the inner basket 22 is equal, and the radius of each transverse bar of the outer basket 23 is equal. The transverse bars and the longitudinal bars are crisscrossed and welded at the intersection to improve the overall structural strength of the cleaning basket 2. The first opening is for water from the spray assembly 3 to pass through. The hollow design of the cleaning basket 2 will not block the spraying and ultrasonic cleaning of fruits and vegetables.

[0096] In some embodiments, Figure 5As shown, a second opening is provided on the partition 11, and the second opening connects 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 wall 15 of the cleaning chamber 1, and the pressure sensor is used to monitor the air pressure in the cleaning space 102.

[0097] 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 to release the pressure, thereby ensuring the safety of the cleaning device.

[0098] Furthermore, if Figure 3 As shown, a side of the partition 11 away from the cleaning space 102 is provided with an inclined surface 111, 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 toward the first door body 12 under the action of their own gravity, and enter the cleaning space 102 from the temporary storage space 101, so that fruits and vegetables are prevented from piling up in the temporary storage space 101.

[0099] In some embodiments, Figure 3 As shown, the cleaning device includes a precooling chamber 6, which 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 connected to the cleaning space 102.

[0100] Specifically, the third door body 61 can adopt an existing automatic door, and the pre-cooling chamber 6 is arranged below the washing chamber 1. After the fruits and vegetables are washed and the surface dehydration is completed, the third door body 61 is controlled to open to allow the fruits and vegetables to enter the pre-cooling chamber 6 from the washing space 102. The pre-cooling chamber 6 is used for pre-cooling the fruits and vegetables after washing, thereby extending the storage time of the fruits and vegetables.

[0101] Alternatively, if Figure 1 As shown, a fifth door 62 is provided on the front side of the pre-cooling chamber 6 (the side facing the user), and the user can take out the processed fruits and vegetables by opening the fifth door 62.

[0102] Furthermore, if Figure 3 As shown, a refrigeration assembly 67 is provided on one side of the pre-cooling chamber 6 , and the pre-cooling chamber 6 is provided with an air outlet 63 and an air return outlet 64 connected to the refrigeration assembly 67 , and the refrigeration assembly 67 is used to provide cold air to the pre-cooling chamber 6 .

[0103] The refrigeration assembly 67 can adopt existing refrigeration devices such as compressors and heat exchangers. The working principle of the refrigeration device can refer to the existing technology and will not be described here. The heat exchanger is equipped with a fan, which is connected to the air outlet 63 to provide cold air to the air outlet 63. The cold air enters the pre-cooling chamber 6 from the air outlet 63 and then leaves from the return air outlet 64, thereby reducing the temperature in the pre-cooling chamber 6, cooling the fruits and vegetables, and extending the storage time of the fruits and vegetables.

[0104] Furthermore, a buffer layer 66 is disposed in the pre-cooling chamber 6 , and the buffer layer 66 is disposed on a side of the pre-cooling chamber 6 away from the cleaning space 102 .

[0105] The buffer layer 66 can be made of a flexible material and is disposed at the bottom of the pre-cooling chamber 6. When the fruits and vegetables enter the pre-cooling chamber 6 from the cleaning chamber 1, the buffer layer 66 plays a buffering role to prevent the fruits and vegetables from being damaged.

[0106] Of course, the buffer layer can be provided inside the pre-cooling chamber 6 to further prevent the fruits and vegetables from being damaged.

[0107] Furthermore, an atomizer 65 and a humidity sensor are provided 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, the atomizer 65 is controlled to be turned on, and the atomizer 65 provides 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, the atomizer 65 is controlled to be turned off, wherein the first humidity threshold is lower than the second humidity threshold.

[0108] In one example, the target humidity range of the precooling chamber 6 is [80%, 90%], if H<80%, the atomizer 65 is controlled to be turned on; if H>90%, the atomizer 65 is controlled to be turned off.

[0109] Furthermore, a temperature sensor is provided inside the precooling chamber 6, and 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, the refrigeration component 67 is controlled to be turned on, and the refrigeration component 67 provides cold air to the precooling chamber 6 to lower the temperature of the precooling chamber 6; if the temperature of the precooling chamber 6 is lower than the second temperature threshold Tm2, ​​the refrigeration component 67 is controlled to be turned off, wherein the second temperature threshold is smaller than the first temperature threshold.

[0110] In one example, the target temperature range of the pre-cooling chamber 6 is [2° C., 8° C.], if T>8° C., the refrigeration component 67 is controlled to be turned on; if T<2° C., the refrigeration component 67 is controlled to be turned off.

[0111] An embodiment of the present application also provides a household appliance, comprising the cleaning device as described above.

[0112] The spray component 3 adjusts the spray pressure and spray time according to the preset type of fruits and vegetables.

[0116] The fruits and vegetables to be cleaned are placed in the temporary storage space 101 of the cleaning chamber 1 of the household appliance. After the preset types of fruits and vegetables are identified, the first door body 12 is controlled to open, and the fruits and vegetables enter the cleaning space 102 from the first door body 12 in sequence, and slowly rotate and roll along the track 21 under the gravity of the fruits and vegetables themselves. At the same time, the spray component 3 adjusts the spray pressure and spray time according to the preset types of fruits and vegetables. The spray component 3 sprays water mist with a certain pressure on the fruits and vegetables to clean the impurities such as residual leaves and mud 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 in all directions at 360 degrees.
