[0037] See also Figures 1 to 8 As shown, according to an embodiment of the present application, a cleaning device is provided, the cleaning device comprising a base station and a cleaning instrument. The base station is used for the cleaning device, and the base station comprises a main body 10 and a refrigeration system 20.

[0038] The main body 10 is provided with an installation cavity 11 and a first delivery channel 13. The refrigeration system 20 includes an evaporator 21, a condenser 22, an exhaust duct 24 and a fan 23. The evaporator 21 and the condenser 22 are arranged side by side in the installation cavity 11 in a direction perpendicular to the height of the base station. The exhaust duct 24 is arranged on the side of the condenser 22 away from the evaporator 21, and the exhaust duct 24 extends to the outer surface of the main body 10. The fan 23 is arranged in the exhaust duct 24. The first delivery channel 13 is used to deliver steam to the evaporator 21.

[0039] Specifically, the main body 10 is also provided with a return groove 12, which is used to store cleaning instruments (such as sweepers, etc.), that is, when the cleaning instrument completes cleaning, it can be returned to the return groove 12. A charging module is also provided in the return groove 12, and the charging module is used to charge the cleaning instrument. When the cleaning instrument returns to the return groove 12, the sewage suction channel 17 is connected to the sewage tank of the cleaning instrument, and the sewage suction channel 17 sucks the sewage in the cleaning instrument into the transfer sewage tank 16 on the main body 10. The transfer sewage tank 16 is provided with a heating module 161, and the first conveying channel 13 is connected to the transfer sewage tank. After the sewage in the cleaning instrument is conveyed to the transfer sewage tank 16 by the sewage suction channel 17, the sewage in the transfer sewage tank 16 is heated and distilled by the heating module 161, and the distilled water vapor enters the evaporator 21 through the first conveying channel 13. In the refrigeration system 20, the evaporator 21 and the condenser 22 are continuously exchanging heat through the compressor 25, so that the temperature of the evaporator 21 is relatively low. After the water vapor contacts the evaporator 21, it is cooled and liquefied into water droplets. The liquefied water droplets are collected and used for cleaning the instrument. The temperature of the condenser 22 rises under the action of the compressor 25, and the heat on the condenser 22 is discharged through the fan 23 and the exhaust duct 24 to complete the heat exchange cycle. At the same time, the fan 23 can also exert a certain suction force on the water vapor, so that the water vapor can adhere to the evaporator 21 under the action of the suction force.

[0040] Compared with the prior art, in this embodiment, the evaporator 21 and the condenser 22 are arranged along a direction perpendicular to the height of the base station (such as the attached Figure 1 The condenser 22 and the evaporator 21 are arranged side by side (in the Z direction), and in this embodiment, only by arranging a fan 23 on the side of the condenser 22 away from the evaporator 21, the refrigeration system 20 can exchange heat with the outside world, and the fan 23 can apply suction to the air in the first conveying channel 13, thereby improving the efficiency of water vapor liquefaction. The base station of this embodiment has a simple structure, and the evaporator 21, the condenser 22 and the fan 23 are compactly arranged, which can reduce the overall volume of the base station to a certain extent, thereby improving the space utilization of the base station.

[0041] Furthermore, the base station further includes a recycling component 30, which includes a water receiving tray 31, a transfer clean water tank 32, and a connecting channel (not shown in the figure). The water receiving tray 31 is arranged at the bottom of the evaporator 21 and the condenser 22. The transfer clean water tank 32 is arranged in the installation cavity 11. The connecting channel is connected between the water receiving tray 31 and the transfer clean water tank 32.

[0042] In this embodiment, the recovery component 30 is used to return the collected clean water to the cleaning instrument. Specifically, a water receiving tray 31 is provided at the bottom of the evaporator 21 and the condenser 22. The water droplets on the evaporator 21 drip into the water receiving tray 31 after being gathered, and the clean water in the water receiving tray 31 flows into the transfer clean water tank 32 through the connecting channel. When it is necessary to replenish clean water for the cleaning instrument, the clean water in the transfer clean water tank 32 is injected into the clean water tank of the cleaning instrument under the action of the pump. In addition, in this embodiment, the water receiving tray 31 is arranged at the bottom of the evaporator 21 and the condenser 22, which can improve the space utilization rate of the base station on the one hand; on the other hand, since the water receiving tray 31 is arranged at the bottom of the evaporator 21 and the condenser 22, when the water droplets on the evaporator 21 are separated from the evaporator 21 under the action of gravity, the water receiving tray 31 can collect the water droplets, thereby preventing the water droplets on the evaporator 21 from falling to other areas, thereby affecting the base station.

[0043] Furthermore, a guide groove 311 is provided at the bottom of the water receiving tray 31 . The cross-sectional area of ​​the guide groove 311 gradually increases along the height direction of the base station. A reflux hole 312 is opened at the bottom of the guide groove 311 , and the end of the connecting channel is connected to the reflux hole 312 .

[0044] Specifically, the "cross section of the guide groove 311" refers to the cross section obtained by cutting the guide groove 311 with a plane perpendicular to the height direction of the base station along the height direction of the base station. Further, along the height direction of the base station, the cross-sectional area of ​​the guide groove 311 gradually increases, so that the guide groove 311 is arranged in a cone or terrace shape, so that the water dripping in the water receiving tray 31 can flow into the transfer clean water tank 32 through the return hole 312 under the action of gravity.

[0045] In addition, the refrigeration system 20 also includes a sealing shell 26, and a sealing cover of the sealing shell 26 is arranged on the outer periphery of the condenser 22 and the evaporator 21, so that a closed chamber is formed between the sealing shell 26, the condenser 22 and the evaporator 21, thereby preventing water vapor in the closed chamber from passing out of the closed chamber, resulting in a significant reduction in the amount of water droplets generated on the evaporator 21.

[0046] Furthermore, the first delivery channel 13 has an outward expansion connection section 131 on one side close to the evaporator 21. The outward expansion connection section 131 is sealed and penetrated in the sealing shell 26, and the cross-sectional area of ​​the outward expansion connection section 131 gradually increases along the direction in which the outward expansion connection section 131 approaches the evaporator 21.

[0047] Specifically, when the sewage of the cleaning instrument is processed and recycled, the sewage suction channel 17 sucks the sewage in the cleaning instrument into the transfer sewage tank 16, and then the heating module 161 on the transfer sewage tank 16 heats the sewage in the transfer sewage tank 16 to evaporate the sewage, and the evaporated water vapor passes through the first delivery channel 13 and enters the sealed shell 26 through the expansion connection section 131. After passing through the evaporator 21, the water vapor in the expansion connection section 131 is cooled and liquefied into water droplets, and the water droplets finally drip into the water receiving tray 31. In addition, the "cross section of the expansion connection section 131" refers to the cross section of the expansion connection section 131 cut perpendicular to the surface along the direction of the expansion connection section 131 close to the evaporator 21. As the cross-sectional area of ​​the outward-expanding connecting section 131 gradually increases in the direction approaching the evaporator 21, the contact area between the water vapor flowing out of the outward-expanding connecting section 131 and the evaporator 21 is larger, which facilitates the evaporator 21 to condense the water vapor, thereby improving the wastewater recovery efficiency of the base station for cleaning instruments.

[0048] Furthermore, the exhaust duct 24 includes a first channel section 241 and a second channel section 242. The first end of the first channel section 241 is arranged close to the side of the condenser 22 away from the evaporator 21. The fan 23 is installed in the first channel section 241. The second channel section 242 is connected to the second end of the first channel section 241 and extends to the outer wall of the main body 10.

[0049] Specifically, the first end of the first channel section 241 is sealed and penetrated in the sealing shell 26, and is arranged close to the side of the condenser 22 away from the evaporator 21. The fan 23 is installed in the first channel section 241, and is arranged close to the side of the condenser 22 away from the evaporator 21. The fan 23 is used to apply suction to the condenser 22 to absorb the heat on the condenser 22 and discharge it to the outside of the base station through the second channel section 242, so as to achieve heat exchange between the condenser 22 and the outside. At the same time, since the fan 23 is arranged on the side of the condenser 22 away from the evaporator 21, and the outward expansion connection section 131 is arranged on the side of the evaporator 21 away from the condenser 22, the outer periphery of the outward expansion connection section 131, the evaporator 21, the condenser 22 and the first end of the first channel section 241 is sealed and connected with the sealing shell 26. Therefore, when the fan 23 is started, the fan 23 can apply suction to the water vapor in the first transmission channel, so that the water vapor in the first transmission channel passes through the outward expansion connection section 131 to the evaporator 21 in turn, and is liquefied into water droplets under the action of the evaporator 21, thereby further improving the wastewater recovery efficiency of the base station for the cleaning instrument.

[0050] Furthermore, the evaporator 21 includes a plurality of fins 211 arranged at intervals, and a hydrophilic film (not shown in the figure) is provided on the outer surface of the fins 211 .

[0051] In this embodiment, the hydrophilic film on the outer surface of the fin 211 has good hydrophilicity and has a greater affinity for water molecules, so that the water vapor in the sealed chamber can quickly gather on the fin 211 and liquefy into water droplets, thereby improving the liquefaction effect of the evaporator 21. In a specific embodiment, the hydrophilic film is a coating on the fin 211, and the hydrophilic film is coated on all the peripheral surfaces of the fin 211. Of course, in consideration of cost, the hydrophilic film is coated on only one surface of each fin 211.

[0052] Furthermore, the base station also includes a second conveying channel 14, a first end of the second conveying channel 14 is connected to the outside of the base station (the first end of the second conveying channel 14 is shown in a closed state in the figure), and a second end of the second conveying channel 14 is connected to the first conveying channel 13.

[0053] The base station of this embodiment also has the function of collecting moisture in the air outside the base station, that is, the dehumidification function. Specifically, when the fan 23 is started, the second conveying channel 14 generates suction on the external air of the base station, and sucks the external air into the second conveying channel 14, and then the air passes through the second conveying channel 14 and enters the first conveying channel 13, and finally enters the sealed shell 26. The moisture in the air in the sealed shell 26 is liquefied into water droplets under the action of the evaporator 21, so that the base station has the function of collecting moisture in the external air. Further, when the external environment of the base station is relatively humid, in order to avoid the influence of the humid environment on the base station and the cleaning equipment, the function of the base station to collect moisture in the external air should be activated at this time.

[0054] In addition, a switching valve 15 is provided at the connection between the second delivery channel 14 and the first delivery channel 13, and the switching valve 15 has a first position for blocking the second delivery channel 14 and a second position for opening the second delivery channel 14. In a specific embodiment, the opening of the second delivery channel 14 is opened on the outward expansion connection section 131. Optionally, the opening of the second delivery channel 14 can also be opened on the outer side wall of the main body 10.

[0055] Specifically, when it is necessary to dehumidify the outside, the switching valve 15 is moved to the second position, the second delivery channel 14 is opened, and the fan 23 applies suction to the second delivery channel 14, and the moisture in the air outside the base station is sucked into the sealed shell 26 through the second channel, and finally the external moisture is liquefied under the action of the evaporator 21, so as to achieve the effect of dehumidifying the outside. When it is necessary to treat the sewage of the cleaning instrument, the switching valve 15 is moved to the second position, at which time the second delivery channel 14 is closed, and the wind applies suction to the first delivery channel 13, and the evaporated water vapor in the sewage tank of the cleaning instrument is sucked into the sealed shell 26, and finally the water vapor is liquefied under the action of the evaporator 21.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0058] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
