[0044] Please refer to Figures 3 to 8 , an embodiment of the present application provides a base device 10, comprising a base 11, a first heat exchange device 12 and a second heat exchange device 13.

[0045] Please refer to Figure 4 , the base 11 includes a bottom case 117 and a top cover 118, the top cover 118 is disposed on the top side of the bottom case 117, and the two define an air duct for air flow to circulate. Please refer to Figure 3 and Figure 8 , Figure 3 and Figure 8 for the arrow indicating the flow path of the air flow in the air duct.

[0046] The first heat exchange device 12 is disposed in the air duct. The second heat exchange device 13 is disposed in the air duct and is disposed downstream of the first heat exchange device 12 along the air flow direction.

[0047] It should be noted that the heat exchange device is used to exchange heat with the air flow flowing through the air duct, so as to realize the condensation dehumidification or heating of the air flow.

[0048] That is, during the heat exchange process of the air flow, the air flow first passes through the first heat exchange device 12 for heat exchange, and then passes through the second heat exchange device 13 for heat exchange.

[0049] Please refer to Figure 4 , the position of the top surface 12a of the first heat exchange device 12 facing the side where the top cover 118 is located is lower than the top surface 13a of the second heat exchange device 13. Thus, a first avoidance space is formed between the top surface 12a of the first heat exchange device 12 and the top cover 118, and other components can be installed in the first avoidance space. That is to say, other components can be installed between the top surface 12a of the first heat exchange device 12 and the top cover 118, and the top cover 118 does not need to protrude upward by a large additional size, which helps to make the structure of the base device 10 compact, thereby helping to reduce the height of the base device 10.

[0050] It is understandable that the top surface 12a of the first heat exchange device 12 refers to the surface where the structure of the first heat exchange device 12 closest to the top cover 118 is located. It can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12. The top surface 13a of the second heat exchange device 13 refers to the surface where the structure of the second heat exchange device 13 closest to the top cover 118 is located. It can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0051] In some embodiments, the above-mentioned first heat exchange device 12 can be an endothermic device, and the second heat exchange device 13 can be an exothermic device. In other embodiments, the above-mentioned first heat exchange device 12 and the second heat exchange device 13 can both be used as endothermic devices. In still other embodiments, the above-mentioned first heat exchange device 12 and the second heat exchange device 13 can both be used as exothermic devices.

[0052] An endothermic device refers to a device that absorbs the heat of the air flow, cools the air flow, and water vapor in the air flow will be condensed into water during the cooling process, so as to realize the function of condensing and dehumidifying the air flow.

[0053] In the embodiments of the present application, the above-mentioned first heat exchange device 12 and the second heat exchange device can both be used as endothermic devices as an example for description. In this embodiment, that is, the first heat exchange device 12 and the second heat exchange device 13 are used to condense and dehumidify the air flow. The air flow entering the air duct first flows through the first heat exchange device 12 and then through the second heat exchange device 13. So that the air flow undergoes double condensation and cooling to improve the condensation and dehumidification effect of the air flow.

[0054] Please refer to Figure 4 and Figure 6 , the base device 10 further includes a third heat exchange device 14. The third heat exchange device 14 is arranged downstream of the second heat exchange device 13 along the air flow direction, and the third heat exchange device 14 is used to heat the air flow.

[0055] Please refer to Figure 1 , the embodiments of the present application further provide 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.

[0056] The clothing treatment device can at least be used to dry clothes.

[0057] In some embodiments, the clothing treatment device includes a heat pump system. The heat pump system includes components such as a compressor, an evaporator, and a condenser. The compressor, the condenser, and the evaporator are connected in series in the refrigerant circuit.

[0058] The working principle of the heat pump system is as follows: The compressor sucks in low-pressure gaseous refrigerant, which is compressed by the compressor and discharged as high-pressure gas. The discharged high-pressure gaseous refrigerant enters the condenser, where the refrigerant is cooled by the ambient temperature air around the condenser and condenses into high-pressure liquid (while transferring heat to the surrounding air). That is to say, the air around the condenser 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, where the liquid refrigerant evaporates and refrigerates (while absorbing heat from the surrounding air). That is to say, the air around the evaporator will be cooled and its temperature will drop. The refrigerant is sucked into the compressor again for pressurization, and so on, continuously circulating to achieve heat exchange.

[0059] In this embodiment, the evaporator can serve as the above-mentioned first heat exchange device 12 and / or second heat exchange device 13. The condenser can serve as the above-mentioned third heat exchange device 14.

[0060] In this embodiment, the drying principle of the laundry treatment device is as follows: The humid and hot air flow discharged from the first laundry treatment chamber 21 enters the air duct, undergoes the first condensation and dehumidification by the first heat exchange device 12, then undergoes the second condensation and dehumidification by the second heat exchange device 13. The cooled air flow is heated by the third heat exchange device 14, and the heated air flow then returns to the first laundry treatment chamber 21 through the air duct. Such a cycle is repeated to achieve continuous drying of the laundry.

[0061] The specific types of the first heat exchange device 12 and the second heat exchange device 13 are not limited. For example, in some embodiments, both the first heat exchange device 12 and the second heat exchange device 13 serve as the evaporator of the above-mentioned heat pump system. That is to say, the heat pump system can be configured with two evaporators. In other embodiments, one of the first heat exchange device 12 and the second heat exchange device 13 is the evaporator of the above-mentioned heat pump system. For example, the first heat exchange device 12 is the evaporator and the second heat exchange device 13 is a liquid cooling device for circulating coolant; or the second heat exchange device 13 is the evaporator and the first heat exchange device 12 is a liquid cooling device. In still other embodiments, both the first heat exchange device 12 and the second heat exchange device 13 can be liquid cooling devices.

[0062] Specifically, a liquid cooling device for circulating a coolant refers to a device into which a coolant can be introduced. During the flow of the coolant in the liquid cooling device, it is beneficial to keep the outer surface of the liquid cooling device at a relatively low temperature. When the air flow in the air duct passes through the outer surface of the liquid cooling device, heat exchange occurs between the liquid cooling device and the air flow. The liquid cooling device absorbs the heat of the air flow and at the same time transfers the heat to the coolant in the liquid cooling device. The coolant heats up while the temperature of the air flow drops, and the water vapor in the air flow reaches the saturation state and condenses into condensed water on the outer surface of the liquid cooling device, thereby achieving the purpose of condensing and dehumidifying the air flow by the liquid cooling device.

[0063] The specific type of the coolant is not limited. In some embodiments, the coolant is water, which can be tap water, brine, etc. In other embodiments, the coolant can also be other liquids.

[0064] Exemplarily, taking the first heat exchange device 12 as a liquid cooling device, the second heat exchange device 13 as an evaporator, and the third heat exchange device 14 as a condenser as an example for description. In this embodiment, the first heat exchange 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 second heat exchange device 13 for the second condensation and dehumidification, further condensing and dehumidifying the air flow. Since the air flow has undergone the first condensation and dehumidification before passing through the second heat exchange device 13, therefore, on the premise of ensuring the condensation and dehumidification effect on the air flow, it helps to reduce the evaporation temperature of the evaporator, thereby reducing the power consumption of the heat pump system.

[0065] It can be understood that in other embodiments, the first heat exchange device 12 can be an evaporator or a liquid cooling device for circulating a coolant, the second heat exchange device 13 can be a condenser, and the third heat exchange device 14 is an electric heating element.

[0066] In this embodiment, the drying principle of the laundry treatment device is as follows: The hot and humid air flow discharged from the first laundry treatment chamber 21 undergoes condensation and dehumidification through the first heat exchange device 12. The air flow after condensation and dehumidification is first heated through the second heat exchange device 13, and the air flow after the first heating is secondarily heated through the third heat exchange device 14. The heated air flow then returns to the first laundry treatment chamber 21 through the air duct, and circulates in this way to achieve continuous drying of the laundry. It can be understood that in this embodiment, the third heat exchange device 14 may not be provided either.

[0067] In other embodiments, the third heat exchange device 14 can also be an electric heating element.

[0068] It should be noted that the low-temperature drying air flow is relative to the hot and humid air flow, and the temperature of the low-temperature drying air flow is lower than that of the hot and humid air flow. The low temperature in the embodiments of the present application can be room temperature.

[0069] In some embodiments, the laundry treatment device includes a cabinet, a second cylinder assembly 30, and a rack 40 disposed within the cabinet.

[0070] The rack 40 is the main support structure for fixedly mounting and supporting other components of the laundry treatment device.

[0071] 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.

[0072] In some embodiments, referring to Figure 2 , the rack 40 includes at least four columns 41, and the four columns 41 respectively extend in the height direction. In the horizontal plane projection, the four columns 41 are distributed at the four vertices of a quadrilateral.

[0073] In the embodiments of the present application, the height direction is Figure 2 and Figure 4 the top-bottom direction in , that is, it includes both the direction from top to bottom and the direction from bottom to top.

[0074] Exemplarily, the base device 10 can be respectively connected to the above four columns 41. The base device 10 is located within the area defined by the four columns 41.

[0075] The base device 10 divides the space within the cabinet into at least a first space and a second space in 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.

[0076] In some embodiments, the first laundry treatment chamber 21 can at least perform a drying treatment on the laundry. The second cylinder assembly 30 has a second laundry treatment chamber 31, and the second laundry treatment chamber 31 can at least perform a washing on the laundry.

[0077] 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.

[0078] In some embodiments, the height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 (please refer to Figure 4) is from 3 mm to 15 mm, that is, 3 mm ≤ h2 ≤ 15 mm. This range forms a first avoidance space with a suitable size between the top surface 12a of the first heat exchange device and the top cover 118, which can not only meet the installation requirements but also will not reduce the size of the first heat exchange device 12 in the height direction due to too large a height difference (taking the position of the top surface 13a of the second heat exchange device 13 as a reference. If the height difference is too large, it means that the height of the first heat exchange device 12 is lower, affecting the heat exchange effect between the first heat exchange device 12 and the air flow).

[0079] Exemplarily, the height difference h2 between the top surface 13a of the second heat exchange device 13 and the top surface 12a of the first heat exchange device 12 is 5 mm.

[0080] In some embodiments, such as Figure 3 shown, the base 11 includes a first support surface 111 and a second support surface 112, and the second support surface 112 is spaced from the bottom wall 11a of the base 11. It should be noted that the first support surface 111 can be a continuous surface or an abstract surface defined by multiple structures, and the second support surface 112 can be a continuous surface or an abstract surface defined by multiple structures.

[0081] The first support surface 111 is located on the bottom side of the first heat exchange device 12 and is used to support the first heat exchange device 12, that is, the first heat exchange device 12 is placed on the first support surface 111.

[0082] In some embodiments, please refer to Figure 4 , the first heat exchange device 12 has a first bottom surface 12b, and the first bottom surface 12b is in contact with the first support surface 111, and the two are substantially at the same height. It should be noted that the first bottom surface 12b can be a continuous surface or an abstract surface defined by multiple structures of the first heat exchange device 12.

[0083] The second support surface 112 is located on the bottom side of the second heat exchange device 13 and is used to support the second heat exchange device 13, that is, the second heat exchange device 13 is placed on the second support surface 112.

[0084] In some embodiments, please refer to Figure 4 , the second heat exchange device 13 has a second bottom surface 13b, and the second bottom surface 13b is in contact with the second support surface 112, and the two are substantially at the same height. It should be noted that the second bottom surface 13b can be a continuous surface or an abstract surface defined by multiple structures of the second heat exchange device 13.

[0085] Among them, please refer to Figure 4, the position of the first support surface 111 is lower than that of the second support surface 112. That is, the position of the first bottom surface 12b of the first heat exchange device 12 is lower than the position of the second bottom surface 13b of the second heat exchange device 13.

[0086] In this embodiment, when the air flow passes through the air duct, the air flow needs to pass through the first heat exchange device 12 first and then flow to the second heat exchange device 13. Since the position of the first support surface 111 is lower than that of the second support surface 112, there is a height difference between the first bottom surface 12b and the second bottom surface 13b, so that the air flow can pass through the first heat exchange device 12 as much as possible and then through the second heat exchange device 13. Although there is a gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 117a of the bottom shell 117, due to the position of the first bottom surface 12b being lower than that of the second bottom surface 13b, the first heat exchange device 12 has a certain shielding effect on the above gap, making the air flow pass through the first heat exchange device 12 as much as possible and then through the second heat exchange device 13, which helps to improve the heat exchange effect of the air flow.

[0087] In some embodiments, the height difference h1 (please refer to Figure 4 ) between the first support surface 111 and the second support surface 112 is 2 mm to 10 mm, that is, 2 mm ≤ h1 ≤ 10 mm. When the height difference between the first support surface 111 and the second support surface 112 is within this range, it can not only maintain the blocking effect of the first heat exchange device 12 on the air flow, but also enable the air flow to enter the second heat exchange device 13 as much as possible after passing through the first heat exchange device 12, and at the same time, it can also ensure that the size of the base device 10 in the height direction of the clothing treatment device is not too high.

[0088] Exemplarily, the height difference h1 between the first support surface 111 and the second support surface 112 is 5 mm.

[0089] In some embodiments, please refer to Figure 4 and Figure 8 , the bottom shell 117 includes a bottom wall 117a and a protruding portion. The protruding portion protrudes from the upper surface of the bottom wall 117a, and the second heat exchange device 13 is supported on the protruding portion so that the bottom surface of the second heat exchange device 13 is spaced from the bottom wall 117a. That is, the second bottom surface 13b is spaced from the bottom wall 117a of the bottom shell 117.

[0090] It can be understood that the bottom wall 117a of the bottom shell 117 in this embodiment is the bottom wall 11a of the base 11.

[0091] In this embodiment, the top surface of the protruding portion defines the second support surface 112 described above. With this arrangement, the liquid precipitated during the heat exchange between the second heat exchange device 13 and the air flow is discharged to the gap between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 117a of the bottom case 117, facilitating the timely discharge of the liquid from this gap and also reducing the risk of the lower part of the second heat exchange device 13 being soaked by the precipitated liquid.

[0092] It should be noted that the specific shape of the protruding portion is not limited, as long as a gap can be formed between the second bottom surface 13b of the second heat exchange device 13 and the bottom wall 117a of the bottom case 117.

[0093] Exemplarily, as Figure 8 shown, the protruding portion includes a plurality of ribs 114, and the top surfaces of at least some of the ribs 114 define the second support surface 112, that is, the plurality of ribs 114 jointly support the second heat exchange device 13.

[0094] In some embodiments, the second heat exchange device 13 extends in the first direction, and the plurality of ribs 114 are arranged at intervals in the first direction. The interval between two adjacent ribs 114 can have a guiding effect on the liquid precipitated from the second heat exchange device 13.

[0095] In some embodiments, the extending direction of the rib 114 intersects the first direction. That is to say, the guiding direction of the rib 114 for the water flow intersects the first direction.

[0096] It should be noted that the extending direction of the rib 114 refers to the direction indicated by the straight line connecting the starting point and the ending point of the rib 114.

[0097] In some embodiments, please refer to Figure 6 and Figure 8 , the base device 10 further includes a retaining rib 15. The retaining rib 15 protrudes from the upper surface of the bottom wall 117a of the bottom case 117 and is provided on the air outlet side of the second heat exchange device 13. The retaining rib 15 extends along the length direction of the second heat exchange device 13 and is used to block the air flow flowing between the bottom surface of the second heat exchange device 13 and the bottom wall 117a.

[0098] In this embodiment, the retaining rib 15 can block the air flow between the bottom surface of the second heat exchange device 13 and the bottom wall 117a, reducing the probability that the air flow directly reaches the third heat exchange device 14 without passing through the heat exchange of the second heat exchange device 13, thereby helping to improve the processing effect of the air flow heat exchange and enhancing the drying effect.

[0099] In some embodiments, the second heat exchange device 13 extends along a first direction, and the first heat exchange device 12 and the second heat exchange device 13 are arranged along a second direction, wherein the first direction and the second direction intersect. For example, the first direction and the second direction are substantially perpendicular.

[0100] It should be noted that the specific directions of the first direction and the second direction are not limited. Exemplarily, the first direction is Figure 3 , Figure 6 and Figure 8 the direction shown by the first direction in Figure 3 , Figure 6 and Figure 8 the direction shown by the second direction in.

[0101] Exemplarily, as shown in Figure 8 , the retaining rib 15 extends along the first direction.

[0102] Exemplarily, one end of the protruding rib 114 is connected to the retaining rib 15, and the other end extends toward one side of the first direction.

[0103] In some embodiments, the position of the top surface of the retaining rib 15 is higher than the second support surface 112, so that the retaining rib 15 can block the air flow, so that the air flow does not pass through the second heat exchange device 13 directly and flows to the third heat exchange device 14 from the gap between the bottom surface of the second heat exchange device 13 and the bottom wall 117a of the bottom case 117.

[0104] In some embodiments, the base device 10 includes functional components, and the functional components are arranged between the top surface of the first heat exchange device 12 and the top cover 118. That is, the functional components are arranged in the first avoidance space.

[0105] It should be noted that the functional components refer to components that can provide some functions other than the heat exchange function.

[0106] In some embodiments, please refer to Figure 5 , at least a part of the top cover 118 protrudes upward to form a second avoidance space 118a below the top cover 118, and at least part of the functional components are arranged in the second avoidance space 118a. That is to say, the functional components are arranged in the avoidance space jointly formed by the first avoidance space and the second avoidance space 118a.

[0107] In some embodiments, the dimension h3 of the second avoidance space 118a in the height direction is 1 mm to 4.5 mm, that is, 1 mm ≤ h3 ≤ 4.5 mm. This range enables the top cover 118 not to protrude upward by a large dimension, and at the same time can provide the second avoidance space 118a for accommodating the spraying device 17. Exemplarily, the dimension h3 of the second avoidance space 118a in the height direction is 1.5 mm.

[0108] In some embodiments, refer to Figure 3 and Figure 4 , the functional component includes a spraying device 17 which has at least one spraying orifice 172 for spraying liquid towards at least one of the second heat exchange device 13, the first heat exchange device 12, and the bottom wall 117a of the bottom shell 117. That is, the spraying device 17 is installed in the avoidance space formed between the top surface 12a of the first heat exchange device 12 and the top cover 118.

[0109] It can be understood that, in some embodiments, the spraying orifice 172 can spray liquid towards the second heat exchange device 13 to remove impurities such as lint attached to the surface of the second heat exchange device 13.

[0110] In some embodiments, the spraying orifice 172 can spray liquid towards the first heat exchange device 12 to remove impurities such as lint attached to the surface of the first heat exchange device 12.

[0111] In some embodiments, the spraying orifice 172 can spray liquid towards the bottom wall 117a of the bottom shell 117 to clean the bottom wall 117a of the bottom shell 117.

[0112] In some embodiments, the spraying orifice 172 can spray liquid towards the second heat exchange device 13 and the first heat exchange device 12. In some embodiments, the spraying orifice 172 can spray liquid towards the second heat exchange device 13 and the bottom wall 117a of the bottom shell 117. In some embodiments, the spraying orifice 172 can spray liquid towards the first heat exchange device 12 and the bottom wall 117a of the bottom shell 117. In some embodiments, the spraying orifice 172 can spray liquid towards the second heat exchange device 13, the first heat exchange device 12, and the bottom wall 117a of the bottom shell 117.

[0113] It should be noted that, in the embodiments where the spraying orifice 172 can spray liquid towards the second heat exchange device 13, the second heat exchange device 13 is a liquid cooling device or an evaporator for circulating coolant. In addition, the liquid sprayed out from the spraying orifice 172 can also be in direct contact with the air flow, which helps to cool the air flow, and thus helps to condense and dehumidify the air flow. It should be noted that, in this embodiment, the air flow may not flow through the spraying device 17.

[0114] In some embodiments, as Figure 7 shown, the spraying device 17 extends along a first direction, the number of the spraying orifices 172 is multiple, the multiple spraying orifices 172 are arranged along the first direction, the spraying orifices 172 are located directly above the windward surface 123 of the first heat exchange device 12, and the spraying orifices 172 are used to spray liquid downward to the top of the windward surface 123.

[0115] In this embodiment, the liquid sprayed from the spray nozzle 172 flows from top to bottom, that is, the liquid flows from the top to the bottom of the windward surface 123. At this time, the liquid basically does not spray obliquely along the airflow direction onto the first heat exchange device 12. Therefore, the liquid will not wash the impurities attached to the windward surface 123 into the interior of the first heat exchange device 12, which is beneficial to the shedding and removal of impurities.

[0116] It should be noted that the windward surface 123 of the first heat exchange device 12 refers to the surface of the first heat exchange device 12 that first contacts the airflow when the airflow passes through the first heat exchange device 12. The windward surface 123 is not a continuous surface, and the airflow needs to pass through the windward surface 123 head-on.

[0117] In some embodiments, the base 11 includes a first region 115 (refer to Figure 7 ) and a drainage channel 116 (refer to Figure 7 ). The drainage channel 116 is provided on one side of the first region 115 along the first direction of the base device 10. The first heat exchange device 12 and the second heat exchange device 13 are both at least partially located in the first region 115.

[0118] The position of the bottom wall 116a of the drainage channel 116 is lower than the bottom wall 115a of the first region 115, so that the water in the first region 115 can flow to the drainage channel 116. That is, the liquid generated by the heat exchange between the first heat exchange device 12 and the second heat exchange device 13 and the airflow first drains to the bottom wall 115a of the first region 115. The water collected by the bottom wall 115a of the first region 115 flows to the drainage channel 116 and then is discharged from the base device 10 through the drainage channel 116.

[0119] In some embodiments, the first direction is the left-right direction of the clothing treatment device. The first heat exchange device 12 and the second heat exchange device 13 are arranged front and back along the clothing treatment device.

[0120] In some embodiments, the first heat exchange device 12 includes a liquid cooling pipeline 121 for circulating the coolant. The liquid cooling pipeline 121 has a liquid inlet 1211, and the liquid inlet 1211 is provided on one side of the liquid cooling device along the first direction of the base device 10 and close to the drainage channel 116. In this way, it is convenient for pipe laying. The liquid inlet 1211 needs to be connected to the water supply component, and the area above the drainage channel 116 can provide enough space for the liquid inlet 1211 and the water supply component.

[0121] In some embodiments, the liquid cooling pipeline 121 further includes a liquid discharge port 1212, and the liquid discharge port 1212 and the liquid inlet 1211 are arranged on the same side of the liquid cooling device along the first direction to facilitate pipe laying.

[0122] In some embodiments, the position of the liquid inlet 1211 is higher than that of the liquid outlet 1212. The height difference between the liquid inlet 1211 and the liquid outlet 1212 is utilized to enable the liquid cooling to flow under its own gravity, thereby reducing the requirement for the water pressure of the water flow at the liquid inlet 1211.

[0123] In some embodiments, the first heat exchange device 12 further includes fins, and the liquid cooling pipeline 121 is passed through the fins. The liquid cooling pipeline 121 transfers its cold quantity to the fins, and when the fins are in contact with 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 and the air flow, thereby enhancing the condensation and dehumidification effect.

[0124] In some embodiments, the spraying device 17 includes a spraying pipeline, and the spraying pipeline has a spraying pipeline water inlet 171 (refer to Figure 3 ), and the spraying pipeline water inlet 171 is arranged on one side of the spraying device 17 along the first direction of the base device 10 and close to the drainage channel 116. In this way, it is convenient for pipeline layout. The spraying pipeline water inlet 171 needs to be connected to the water supply component, and the area above the drainage channel 116 can provide sufficient space for the spraying pipeline water inlet 171 and the water supply component.

[0125] It can be understood that in some embodiments, the liquid inlet 1211 and the spraying pipeline water inlet 171 can be both arranged close to the drainage channel 116. At this time, the same water supply component can be used to supply water to the liquid inlet 1211 and the spraying pipeline water inlet 171 simultaneously, which is convenient for pipeline layout, helps to save the layout space, and can also save the layout cost.

[0126] Exemplarily, please refer to Figure 4 and Figure 5 , the base device 10 includes a flexible barrier portion 18, and the flexible barrier portion 18 is arranged between the top surface of the third heat exchange device 14 and the top cover 118; and / or, the flexible barrier portion 18 is arranged between the top surface of the second heat exchange device 13 and the top cover 118; and / or, the flexible barrier portion 18 is arranged between the top surface of the first heat exchange device 12 and the top cover 118. That is to say, among the three positions between the top surface of the third heat exchange device 14 and the top cover 118, between the top surface of the second heat exchange device 13 and the top cover 118, and between the top surface of the first heat exchange device 12 and the top cover 118, any one of the positions can be provided with the flexible barrier portion 18, or any two of the positions can be provided with the flexible barrier portion 18, or all three positions can be provided with the flexible barrier portion 18.

[0127] The flexible barrier portion 18 is used to block the air flow and the lint in the air flow, so that the air flow preferably flows through the above-mentioned first heat exchange device 12, second heat exchange device 13 and third heat exchange device 14.

[0128] In some embodiments, the flexible barrier portion 18 includes a sponge structure and / or a felt structure. Both the sponge and the felt have good softness and elasticity, and are suitable for deformation to fit the installation space.

[0129] It can be understood that, in some embodiments, the flexible barrier portion 18 may include a sponge structure. In some embodiments, the flexible barrier portion 18 may include a felt structure. In some embodiments, the flexible barrier portion 18 may include both a sponge structure and a felt structure at the same time. In this case, the flexible barrier portion 18 may be arranged as a double-layer structure.
