[0040] Please refer to Figures 3 to 9 , the embodiment of the present application provides a base device 10, which includes a base 11 and a heat absorption component.

[0041] Please refer to Figure 3 and Figure 5 , the base 11 has an air duct and a drainage channel 116.

[0042] The air duct is used for the air flow to circulate, as shown in Figure 3 , Figure 5 and Figure 8 , the arrows in Figure 3 , Figure 5 and Figure 8 indicate the flow path of the air flow in the air duct. The air duct includes a heat absorption component installation area 115, the heat absorption component installation area 115 is communicated with the drainage channel 116, and the liquid on the upper surface of the bottom wall 115a of the heat absorption component installation area 115 can be discharged to the drainage channel 116.

[0043] In some embodiments, please refer to Figure 5 , the bottom wall 115a of the heat absorption component installation area 115 includes a first part 1151 and a second part 1153, the position of the second part 1153 is lower than that of the first part 1151, so that the liquid of the first part 1151 can be discharged to the second part 1153, and the second part 1153 is used to guide the liquid to the drainage channel 116. On the one hand, the second part 1153 can play a role in liquid drainage and guiding, and on the other hand, since the position of the second part 1153 is lower than that of the first part 1151, the liquid of the second part 1153 is less likely to flow back to the first part 1151.

[0044] The heat absorption component is disposed in the heat absorption component installation area 115 and at least partially located above the first part 1151. The liquid generated by the heat absorption component during the condensation dehumidification process is at least partially discharged to the first part 1151 and then flows through the second part 1153 to the drainage channel 116. Since the position of the second part 1153 is lower than that of the first part 1151, it helps to reduce the probability that the liquid in the second part 1153 flows along the upper surface of the bottom wall 115a of the heat absorption component installation area 115 towards the downstream of the air duct under the carrying action of the air flow.

[0045] In some embodiments, a step structure 1154 is formed at the junction of the first part 1151 and the second part 1153. The step structure 1154 can better block the water in the second part 1153, thereby further reducing the probability that the liquid in the second part 1153 flows along the upper surface of the bottom wall 115a of the heat absorption component installation area 115 towards the downstream of the air duct under the carrying action of the air flow.

[0046] It should be noted that the heat absorption component refers to a component that absorbs the heat of the air flow, cools the air flow, and the water vapor in the air flow will be condensed into water during the cooling process, thereby realizing the condensation dehumidification function of the air flow, that is, the heat absorption component is used to perform the condensation dehumidification on the air flow.

[0047] In some embodiments, the base device 10 further includes a heat release device. The heat release device is disposed downstream of the heat absorption component along the air flow direction, and the heat release device is used to heat the air flow.

[0048] Please refer to Figure 1 , the embodiment of the present application further provides a clothing treatment device, including a first cylinder assembly 20 and the base device 10 of any embodiment of the present application. The first cylinder assembly 20 has a first clothing treatment cavity 21, and the air duct is communicated with the first clothing treatment cavity 21. The first cylinder assembly 20 is used to care for clothes.

[0049] The clothing treatment device can at least be used to dry clothes.

[0050] The drying principle of the clothing treatment device provided by the embodiment of the present application is as follows: The humid and hot air flow discharged from the first clothing treatment cavity 21 enters the air duct, is subjected to condensation dehumidification by the heat absorption component, the air flow after condensation dehumidification is heated by the heat release device, and the heated air flow then returns to the first clothing treatment cavity 21 through the air duct. In this way, continuous drying of clothes is achieved by circulation.

[0051] It should be noted that the low-temperature drying air flow is relative to the humid and hot air flow, and the temperature of the low-temperature drying air flow is lower than that of the humid and hot air flow. The low temperature in the embodiment of the present application can be room temperature.

[0052] In some embodiments, please refer to Figure 1, the laundry treatment device includes a cabinet, a second cylinder assembly 30, and a rack 40 disposed within the cabinet.

[0053] The rack 40 is the main support structure for the fixed installation and support of other components of the laundry treatment device.

[0054] The base device 10 is disposed on the rack 40, and the base device 10 and its load transfer the acting force to the rack 40.

[0055] In some embodiments, as Figure 2 shown, the rack 40 includes at least four upright columns 41, and the four upright columns 41 extend along the height direction respectively. In the horizontal plane projection, the four upright columns 41 are distributed at the four vertices of a quadrilateral.

[0056] Exemplarily, as Figure 2 shown, the base device 10 can be respectively connected to the above four upright columns 41. The base device 10 is located within the area defined by the four upright columns 41.

[0057] The base device 10 divides the space within the cabinet into at least a first space and a second space along the height direction. The first cylinder assembly 20 is disposed in the first space, and the second cylinder assembly 30 is disposed in the second space.

[0058] It should be noted that, as Figure 1 , Figure 2 and Figure 6 shown, the height direction of the laundry treatment device is the top-bottom direction, which can also be called the up-down direction. It includes both the direction from the top to the bottom and the direction from the bottom to the top.

[0059] In some embodiments, the first laundry treatment chamber 21 can at least dry the laundry. The second cylinder assembly 30 has a second laundry treatment chamber 31, and the second laundry treatment chamber 31 can at least wash the laundry.

[0060] In some embodiments, the first space is above the second space, that is, the position of the first cylinder assembly 20 is higher than the position of the second cylinder assembly 30. In other embodiments, the first space can also be below the second space, that is, the position of the second cylinder assembly 30 is higher than the position of the first cylinder assembly 20.

[0061] In some embodiments, the laundry treatment device includes a heat pump system. The heat pump system includes components such as a compressor, an evaporator 13, and a condenser 14. The compressor, the condenser 14, and the evaporator 13 are connected in series in the refrigerant circuit.

[0062] The working principle of the heat pump system is as follows: The compressor sucks in low-pressure gaseous refrigerant, compresses it, and discharges it as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser 14, where the refrigerant is cooled by the ambient-temperature air around the condenser 14 and condenses into high-pressure liquid (while transferring heat to the surrounding air). That is to say, the air around the condenser 14 will be heated and its temperature will rise. After the high-pressure liquid refrigerant flows through the throttling device for throttling and pressure reduction, it becomes a low-pressure and low-temperature gas-liquid two-phase mixture. The gas-liquid two-phase mixture enters the evaporator 13, where the liquid refrigerant evaporates and refrigerates (while absorbing heat from the surrounding air). That is to say, the air around the evaporator 13 will be cooled and its temperature will drop. The refrigerant is sucked into the compressor again for pressurization, and so on, repeating continuously to achieve heat exchange.

[0063] In this embodiment, the evaporator 13 can be a part of the above-mentioned heat absorption component. The condenser 14 can be the above-mentioned heat release device.

[0064] In other embodiments, the heat release device can also be an electric heating element.

[0065] In some embodiments, such as Figure 6 shown, the heat absorption component includes a liquid cooling device 12 for circulating coolant.

[0066] Specifically, coolant can be introduced into the liquid cooling device 12. During the flow of the coolant in the liquid cooling device 12, it is beneficial to keep the outer surface of the liquid cooling device 12 at a relatively low temperature. When the air flow in the air duct flows through the outer surface of the liquid cooling device 12, heat exchange occurs between the liquid cooling device 12 and the air flow. The liquid cooling device 12 absorbs the heat of the air flow and at the same time transfers the heat to the coolant in the liquid cooling device 12. The coolant temperature rises while the air flow temperature drops. The water vapor in the air flow reaches the saturation state and condenses into condensate on the outer surface of the liquid cooling device 12. The condensate drains to the bottom wall 115a of the heat absorption component installation area 115, thereby achieving the purpose of condensing and dehumidifying the air flow by the liquid cooling device 12.

[0067] It should be noted that in some embodiments, the heat absorption component can only include the evaporator 13; in some embodiments, the heat absorption component can only include the liquid cooling device 12; in some embodiments, the heat absorption component can include both the liquid cooling device 12 and the evaporator 13.

[0068] In the embodiments of the present application, an example is described in which the heat absorption component includes a liquid cooling device 12, an evaporator 13, and a condenser 14 as a heat dissipation device. In this embodiment, the condenser 14 is provided downstream of the evaporator 13 and the liquid cooling device 12 along the air flow direction. It can be understood that the condenser 14 being provided downstream of the evaporator 13 and the liquid cooling device 12 along the air flow direction means that the air flow in the air duct needs to pass through the evaporator 13 and the liquid cooling device 12 first and then enter the condenser 14, but the order of the air flow passing through the evaporator 13 and the liquid cooling device 12 is not limited.

[0069] It should be noted that, in this embodiment, the evaporator 13 may be located upstream of the liquid cooling device 12 along the air flow direction, that is, the air flow passes through the evaporator 13 first and then through the liquid cooling device 12; the evaporator 13 may also be located downstream of the liquid cooling device 12 along the air flow direction, that is, the air flow passes through the liquid cooling device 12 first and then through the evaporator 13.

[0070] In the embodiments of the present application, an example is described in which the evaporator 13 is located downstream of the liquid cooling device 12 along the air flow direction. In this embodiment, the air flow first passes through the liquid cooling device 12, then through the evaporator 13, and then enters the condenser 14.

[0071] In this embodiment, the liquid cooling device 12 performs the first condensation and dehumidification on the air flow entering the air duct, reducing the temperature, humidity of the air flow, and intercepting a part of impurities such as lint. The air flow after the first condensation and dehumidification passes through the evaporator 13 for the second condensation and dehumidification, further condensing and cooling the air flow. Since the air flow has undergone the first condensation and dehumidification before passing through the evaporator 13, therefore, while ensuring the condensation and dehumidification effect on the air flow, it helps to reduce the evaporation temperature of the evaporator 13, thereby reducing the power consumption of the heat pump system.

[0072] In some embodiments, please refer to Figure 3 and Figure 4 , the drainage channel 116 is located on one side of the heat absorption component installation area 115 along the first direction. A communication port 1161 is provided on the side wall of the drainage channel 116 close to the second part 1153. That is, the liquid of the second part 1153 is discharged to the drainage channel 116 through the communication port 1161.

[0073] Exemplarily, the first direction is the direction shown in Figure 3 , Figure 5 , Figure 6 and Figure 8 .

[0074] In some embodiments, such as Figure 5As shown, one end of the second part 1153 extends to the communication port 1161. That is to say, the liquid of the second part 1153 can be directly discharged into the drainage channel 116 through the communication port 1161 without setting other diversion structures, which helps to save the layout space of the heat absorption component installation area 115 and also saves the manufacturing cost.

[0075] In some embodiments, such as Figure 9 As shown, the base 11 includes a bottom wall portion 11a, and a part of the bottom wall portion 11a is recessed to form a drainage channel 116. The space in the drainage channel 116 is for the liquid to flow. At this time, the position of the bottom wall 116a of the drainage channel 116 is lower than the bottom wall 115a of the heat absorption component installation area 115, so that the water in the heat absorption component installation area 115 can flow into the drainage channel 116.

[0076] It should be noted that the bottom walls in the bottom wall 116a of the drainage channel 116 and the bottom wall 115a of the heat absorption component installation area 115 refer to the surfaces. That is, the bottom wall 116a of the drainage channel 116 refers to the upper surface of the bottom wall 116a of the drainage channel 116, and the bottom wall 115a of the heat absorption component installation area 115 refers to the upper surface of the bottom wall 115a of the heat absorption component installation area 115. The bottom wall portion 11a of the base 11 refers to a solid structure.

[0077] Exemplarily, such as Figure 3 As shown, the drainage channel 116 includes a first side wall 1162 and a second side wall 1163 that are oppositely arranged in the first direction. Both the first side wall 1162 and the second side wall 1163 extend in the second direction, and the second direction intersects the first direction, for example, is substantially perpendicular.

[0078] In this embodiment, the first side wall 1162 is located on the side of the second side wall 1163 close to the heat absorption component installation area 115, and the communication port 1161 is provided on the first side wall 1162. That is, the first side wall 1162 is the junction of the heat absorption component installation area 115 and the drainage channel 116, and the communication port 1161 is provided on the first side wall 1162, so that the water in the heat absorption component installation area 115 is directly discharged into the drainage channel 116 through the communication port 1161.

[0079] In the embodiment where the evaporator 13 is located downstream of the liquid cooling device 12 in the air flow direction, a part of the evaporator 13 is located above the first part 1151. That is to say, the liquid generated during the condensation and dehumidification process of the evaporator 13 first flows through the first part 1151, then is discharged to the second part 1153, and finally is discharged to the drainage channel 116 through the communication port 1161.

[0080] In some embodiments, please refer to Figure 3 and Figure 5, the second part 1153 includes a flattening sub - part 11531 and a diversion sub - part 11532. The diversion sub - part 11532 is located at one end of the flattening sub - part 11531 close to the drainage channel 116. Along the direction close to the drainage channel 116, the diversion sub - part 11532 slopes downward. At this time, the downward - sloping diversion sub - part 11532 can play a better role in diverting the liquid in the second part 1153, making the liquid in the second part 1153 drain more smoothly into the drainage channel 116.

[0081] Exemplarily, the second direction is Figure 3 , Figure 5 , Figure 6 and Figure 8 the direction shown in.

[0082] In some embodiments, as Figure 3 and Figure 5 shown, the diversion sub - part 11532 slopes downward and extends to the communication port, that is, it helps to make the size of the communication port 1161 larger in the height direction, and helps to make the liquid in the second part 1153 be drained into the drainage channel 116 more timely, improving the drainage effect of the base device 10.

[0083] In some embodiments, as Figure 8 shown, a part of the liquid - cooling device 12 is supported on the flattening sub - part 11531, that is, the flattening sub - part 11531 can provide a supporting function for the liquid - cooling device 12, which is beneficial to the horizontal placement of the liquid - cooling device 12.

[0084] Exemplarily, as Figure 9 shown, the bottom surface 12b of the liquid - cooling device 12 is spaced from the diversion sub - part 11532 in the height direction, which helps to reduce the influence of the liquid - cooling device 12 on the diversion of the diversion sub - part 11532.

[0085] It should be noted that the fact that the position of the second part 1153 is lower than that of the first part 1151 means that the position of the second part 1153 is lower than that of the first part 1151 at their junction. For example, the position of the flattening sub - part 11531 is lower than that of the first part 1151 at their junction, and the position of the diversion sub - part 11532 is lower than that of the first part 1151 at their junction.

[0086] In some embodiments, as Figure 3 and Figure 5 shown, the step structure 1154 includes a first step structure 11541. A first step structure 11541 is formed at the junction of the diversion sub - part 11532 and the first part 1151. The size of the end of the first step structure 11541 close to the drainage channel 116 in the height direction is larger than the size of the end of the first step structure 1154 away from the drainage channel 116 in the height direction.

[0087] In this embodiment, the liquid enters the drainage channel 116 through the deflector part 11532. The closer to the drainage channel 116, the greater the liquid flow rate. When approaching the drainage channel 116, the dimension of the first step structure 11541 in the height direction is larger, so that the first step structure 11541 can better block the liquid in the deflector part 11532, thereby helping to further reduce the probability that the liquid in the deflector part 11532 flows downstream along the upper surface of the bottom wall of the heat absorption component installation area 115 under the carrying action of the air flow.

[0088] In this embodiment, the first step structure 11541 forms a part of the step structure 1154.

[0089] In some embodiments, the step structure 1154 further includes a second step structure 11542, and the second step structure 11542 is formed at the junction of the leveling part 11531 and the first part 1151. The second step structure 11542 forms another part of the step structure 1154.

[0090] It can be understood that the first step structure 11541 and the second step structure 11542 can be formed as an integral structure or separated, which is not limited herein.

[0091] In some embodiments, as Figure 4 shown, the first step structure 11541 includes a first step stage 115411 and a second step stage 115412 that are connected to each other. Along the direction approaching the drainage channel 116, the first step stage 115411 extends obliquely away from the evaporator 13; the second step stage 115412 extends from the extension end of the first step stage 115411 toward the evaporator 13 so that the second step stage 115412 faces the communication port 1161. Thereby, the second step stage 115412 can better block the liquid in the drainage channel 116 to reduce the probability that the liquid in the drainage channel 116 flows to the first part 1151 under the negative pressure action of the air flow, and thus reduce the probability that the liquid in the drainage channel 116 flows downstream along the upper surface of the bottom wall of the heat absorption component installation area 115 under the carrying action of the air flow.

[0092] In some embodiments, as Figure 8 shown, the base device 10 includes a spraying device 17. The spraying device 17 is at least partially located in the heat absorption component installation area 115. The spraying device 17 has a spraying port 172, and the spraying port 172 is used to spray liquid toward at least one of the bottom wall 115a of the heat absorption component installation area 115, the evaporator 13, and the liquid cooling device 12.

[0093] In this embodiment, the liquid sprayed by the spraying device 17 is conducive to flushing the impurities adhering to one or more of the upper surface of the bottom wall 115a of the heat absorption component installation area 115, the surface of the evaporator 13, and the surface of the liquid cooling device 12, which is conducive to achieving the self-cleaning effect of the base device 10. In addition, the liquid sprayed by the spraying device 17 contacts the air flow in the air duct, which can also assist in cooling and dehumidifying the air flow. The liquid sprayed by the spraying device 17 is also conducive to capturing the impurities carried in the air flow.

[0094] In some embodiments, the spray orifice 172 is only used to spray liquid towards one of the bottom wall 115a of the heat absorption component installation area 115, the evaporator 13, and the liquid cooling device 12. For example, it only sprays liquid towards the bottom wall 115a of the heat absorption component installation area 115, or only towards the evaporator 13, or only towards the liquid cooling device 12. In some other embodiments, the spray orifice 172 is used to spray liquid towards any two of the bottom wall 115a of the heat absorption component installation area 115, the evaporator 13, and the liquid cooling device 12. For example, it sprays liquid towards the bottom wall 115a of the heat absorption component installation area 115 and the evaporator 13, or towards the bottom wall 115a of the heat absorption component installation area 115 and the liquid cooling device 12, or towards the evaporator 13 and the liquid cooling device 12. In still some other embodiments, the spray orifice 172 is used to spray liquid towards the bottom wall 115a of the heat absorption component installation area 115, the evaporator 13, and the liquid cooling device 12.

[0095] In some embodiments, the spraying device 17 extends along the first direction, the number of spray orifices 172 is multiple, and the multiple spray orifices 172 are arranged along the first direction. The spraying device 17 is used to spray liquid towards the liquid cooling device 12.

[0096] In the embodiment where the heat absorption component includes the liquid cooling device 12 and the evaporator 13 located downstream of the liquid cooling device 12, since the liquid cooling device 12 is arranged upstream of the evaporator 13, relatively more impurities adhere to the surface of the liquid cooling device 12. Therefore, spraying liquid towards the liquid cooling device 12 by the spraying device 17 can achieve the self-cleaning effect of the liquid cooling device 12.

[0097] In the embodiment where the liquid cooling device 12 is located above the guiding sub-part 11532, the liquid for cleaning the liquid cooling device 12 is discharged to the guiding sub-part 11532. The inclined guiding sub-part 11532 can provide a guiding effect for the cleaned liquid, so that after the liquid mixed with impurities is discharged to the guiding sub-part 11532, it can quickly flow to the drainage channel 116, that is, the liquid mixed with impurities is not likely to accumulate on the surface of the guiding sub-part 11532.

[0098] In some embodiments, such as Figure 9As shown, the spray port 172 is located above the windward surface 122 of the liquid cooling device 12, and the spray port 172 is used to spray liquid downward to the windward surface 122. In this embodiment, the liquid sprayed from the spray port 172 flows from top to bottom, that is, the liquid flows from the top of the windward surface 122 to the bottom of the windward surface 122. At this time, the liquid will basically not be sprayed to the liquid cooling device 12 in an inclined direction along the airflow direction. Therefore, the liquid will not wash the impurities attached to the windward surface 122 into the interior of the liquid cooling device 12, which is conducive to the shedding and removal of impurities.

[0099] It should be noted that the windward surface 122 of the liquid cooling device 12 refers to the surface of the liquid cooling device 12 that first contacts the airflow when the airflow passes through the liquid cooling device 12. The windward surface 122 is not a continuous surface, and the airflow needs to pass through the windward surface 122 head-on.

[0100] In some embodiments, Figure 6 As shown, the base device 10 includes a cover plate 16, which is arranged on the top side of the drainage channel 116. The cover plate 16 can block the water in the drainage channel 116 from forming water vapor under the negative pressure of the air flow and entering the downstream of the air duct as much as possible, thereby preventing the water vapor from entering the first laundry processing chamber 21 as much as possible.

[0101] In some embodiments, Figure 6 and Figure 9 As shown, one end of the liquid cooling device 12 close to the drainage channel 116 is supported on the cover plate 16. On the one hand, the cover plate 16 can provide support for the liquid cooling device 12, which helps to improve the installation stability of the liquid cooling device 12. On the other hand, it also enables the space above the drainage channel 116 to be effectively utilized, which helps to reduce the space occupied by the liquid cooling device 12 in the first direction of the heat absorption component installation area 115, which is conducive to making the base device 10 compact in structure.

[0102] In some embodiments, the liquid cooling device 12 has a drain port 1212, which is located above the cover plate 16, and the cover plate 16 is provided with a liquid port 161, or at least a portion of the drainage channel 116 not covered by the cover plate 16 forms a liquid port 161, so that the coolant discharged from the drain port 1212 is discharged into the drainage channel 116 through the liquid port 161. In other words, a large amount of coolant discharged from the liquid cooling device 12 does not need to pass through the bottom wall of the heat absorption component installation area 115, which can ensure that the coolant of the liquid cooling device 12 can be discharged in time on the one hand, and can also reduce the influence of the coolant discharged from the liquid cooling device 12 on other components of the heat absorption component installation area 115.

[0103] It should be noted that the liquid passing port 161 is provided on the cover plate 16, and the cover plate 16 independently defines the shape of the liquid passing port 161. The area not covered by the cover plate 16 means that the liquid passing port 161 is located outside the overall contour of the appearance of the cover plate 16. For example, if the length of the drainage channel 116 is 100 cm and the length of the cover plate 16 is 80 cm, and there is a 20 cm interval between the end of the cover plate 16 and the end of the drainage channel 116, then this interval constitutes the above-mentioned liquid passing port 161.

[0104] In some embodiments, in the horizontal plane projection, the liquid discharge port 1212 is located within the projection range of the liquid passing port 161. That is to say, along the height direction of the laundry treatment device, the coolant discharged from the liquid discharge port 1212 can directly flow through the liquid passing port 161 under the action of gravity and enter the drainage channel 116, which helps to improve the drainage efficiency, and there is no need to arrange a drainage pipe from the liquid discharge port 1212 to the liquid passing port 161, which helps to save the layout space and layout cost.

[0105] In some embodiments, as Figure 6 shown, the liquid cooling device 12 includes a liquid cooling pipeline 121 for circulating the coolant. The end of the liquid cooling pipeline 121 forms a liquid discharge port 1212. The liquid cooling pipeline 121 further includes a liquid inlet 1211. The liquid inlet 1211 and the liquid discharge port 1212 are provided on the same side of the liquid cooling device 12 along the first direction. The liquid inlet 1211 and the liquid discharge port 1212 being provided on the same side of the liquid cooling device 12 can facilitate pipe laying.

[0106] Moreover, the liquid inlet 1211 needs to be connected to a water supply component. Both the liquid inlet 1211 and the liquid discharge port 1212 are provided above the drainage channel 116. The area above the drainage channel 116 can provide sufficient space for the liquid inlet 1211 and the water supply component.

[0107] In some embodiments, the position of the liquid inlet 1211 is higher than the position of the liquid discharge port 1212. The height difference between the liquid inlet 1211 and the liquid discharge port 1212 enables the water in the liquid cooling pipeline 121 to flow under its own gravity, thereby reducing the requirement for the water pressure of the water flowing into the liquid inlet 1211.

[0108] In some embodiments, the liquid cooling device 12 further includes fins, and the liquid cooling pipeline 121 passes through the fins. The liquid cooling pipeline 121 transfers its cold quantity to the fins, and when the fins contact the air flow, the cold quantity is transferred to the air flow. The fins help to increase the contact area between the liquid cooling device 12 and the air flow, thereby improving the condensation and dehumidification effect.

[0109] In some embodiments, a part of the evaporator 13 is located above the first part 1151. The condensed water generated by the evaporator 13 condensing and cooling the air flow passes through the first part 1151 and is discharged to the second part 1153, and then is guided to the drainage channel 116 through the second part 1153.

[0110] Another part of the evaporator 13 is located above the drainage channel 116. Refer to Figure 7 , one end of the evaporator 13 in the first direction is located above the drainage channel 116, so that the space above the drainage channel 116 is effectively utilized, which helps to reduce the occupied space of the evaporator 13 in the first direction on the heat absorption component installation area 115, and is beneficial to making the structure layout of the base device 10 compact.

[0111] In the embodiment with the cover plate 16, one end of the evaporator 13 in the first direction is located above the cover plate 16.

[0112] In some embodiments, the base device 10 includes a protruding portion, which protrudes from the surface of the first part 1151, and the evaporator 13 is supported on the protruding portion, so that the bottom surface of the evaporator 13 is spaced apart from the first part 1151. This facilitates the timely discharge of condensed water from this gap and also reduces the risk of the lower part of the evaporator 13 being soaked by the condensed water precipitated.

[0113] It should be noted that the specific shape of the protruding portion is not limited, as long as it can form a gap between the bottom surface of the evaporator 13 and the first part 1151.

[0114] Exemplarily, as Figure 3 and Figure 5 shown, the protruding portion includes a plurality of ribs 114, that is, the plurality of ribs 114 jointly support the evaporator 13.

[0115] In some embodiments, the plurality of ribs 114 are spaced apart, and the gap between adjacent two ribs 114 can also play a guiding role in the condensed water precipitated from the evaporator 13.

[0116] Exemplarily, as Figure 3 and Figure 5 shown, the plurality of ribs 114 are arranged at intervals in the first direction, and the extending directions of the plurality of ribs 114 all intersect with the first direction.
