[0040] This application provides a dehumidifier 10 for use in clothing processing equipment. Please refer to [link / reference]. Figures 2 to 7 It includes the box body 111 and the box lid 112.

[0041] The dehumidifier 10 is a device that uses condensate to condense and dehumidify hot and humid airflow. The condensate can be water or other cooling medium. In this embodiment, the condensate is water.

[0042] Please see Figure 3 , Figure 6 and Figure 7The box body 111 is provided with a heat exchange cavity 111a and a water outlet 111b in communication with the heat exchange cavity 111a.

[0043] Please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The box cover 112 is provided with a water passing cavity 112b, a water inlet 112a and a plurality of spray holes 112c in communication with the water passing cavity 112b. The box cover 112 covers the top of the box body 111. The water inlet 112a and the water outlet 111b form a condensate flow path passing through the water passing cavity 112b, the spray holes 112c and the heat exchange cavity 111a, that is, the box body 111 and the box cover 112 jointly constitute a heat exchange box 11 that can be used for heat exchange. The condensate enters the water passing cavity 112b from the water inlet 112a, and is then sprayed into the heat exchange cavity 111a through the spray holes 112c.

[0044] Please refer to Figure 3 , Figure 6 and Figure 7 The dehumidifier 10 is further provided with an air inlet and an air outlet 111c in communication with the heat exchange cavity 111a, Figure 3 , Figure 6 and Figure 7 The air inlet and the air outlet 111c are both arranged on the box body 111. In some embodiments, one of the air inlet and the air outlet 111c can be arranged on the box body 111, and the other can be arranged on the box cover 112. The box body 111 is provided with an air inlet and an air outlet 111c in communication with the heat exchange cavity 111a. The air inlet and the air outlet 111c form an air flow path. That is, the air flows into the heat exchange cavity 111a from the air inlet, flows along the air flow path, and then flows out from the air outlet 111c. The condensate sprayed into the heat exchange cavity 111a directly contacts and exchanges heat with the air flowing into the heat exchange cavity 111a, so as to absorb the heat of the air. The water vapor in the heat-exchanged air condenses into water droplets due to the temperature drop, and the water droplets mix with the condensate. Finally, the water droplets are discharged from the water outlet 111b. In this way, the effect of condensing and dehumidifying the air is achieved.

[0045] The dehumidifier 10 of the embodiments of the present application can be used in any appropriate occasion. Exemplarily, the embodiments of the present application are described by taking the application of the dehumidifier 10 in a clothes treatment apparatus as an example.

[0046] Exemplarily, the embodiments of the present application provide a clothes treatment apparatus. Please refer to Figure 1, including the cylinder assembly 20, the air guide device 30, and the dehumidifier 10 of any embodiment of the present application. The cylinder assembly 20 is provided with a clothes treatment cavity, an air inlet, and an air outlet; the dehumidifier 10 includes an air inlet and an air outlet 111c, the air inlet is in communication with the air outlet, and the air outlet 111c is in communication with the outside; the air inlet is in communication with the outside through the air guide device 30.

[0047] The clothes treatment device can be a clothes dryer, a washer-dryer, etc., which is not limited herein. The clothes treatment device can be a drum-type clothes treatment device or a pulsator-type clothes treatment device.

[0048] The air guide device 30 is configured with a fan and a heating assembly, and the air guide device 30 can heat the fresh air from the outside and introduce it into the clothes treatment cavity through the air inlet. In the clothes treatment cavity, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs the moisture in the clothes, becomes a wet hot air flow, and flows out of the air outlet of the clothes treatment cavity.

[0049] The air outlet of the clothes treatment cavity is in communication with the air inlet of the dehumidifier 10, and the wet hot air flow flowing out of the air outlet of the clothes treatment cavity enters the dehumidifier 10 through the air inlet to be condensed and dehumidified to form a low-temperature dry air flow, which is discharged from the air outlet 111c and enters the surrounding environment.

[0050] In an embodiment, the air outlet 111c of the dehumidifier 10 is in communication with the detergent box, that is, the low-temperature dry air flow is discharged to the surrounding environment through the detergent box. In some embodiments, the air outlet 111c can also be directly in communication with the outside.

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

[0052] The dehumidifier 10 of the embodiment of the present application is provided with a box body 111 having a heat exchange cavity 111a and a water outlet 111b, and a box cover 112 having a water passing cavity 112b, a water inlet 112a, and a plurality of spray holes 112c. The condensed liquid flowing into the water passing cavity 112b from the water inlet 112a can be relatively dispersedly sprayed into the heat exchange cavity 111a through the spray holes 112c, so that the condensed liquid can share the same fluid channel with the air flow flowing into the heat exchange cavity 111a in the heat exchange cavity 111a for sufficient direct contact, thereby enabling the condensed liquid and the air flow to exchange heat sufficiently, and further having a better condensation and dehumidification effect.

[0053] In addition, the dehumidifier 10 can be used to condense and dehumidify the humid hot air flow discharged from the clothes treatment cavity of the clothes treatment device. The air flow condensed and dehumidified by the dehumidifier 10 is discharged through the air outlet 111c and enters the indoor environment, that is, the air flow discharged to the surrounding environment is condensed and dehumidified by the condensing device, so as not to significantly affect the temperature and humidity of the indoor environment, reduce the influence on the indoor environment, and thus improve the user experience.

[0054] In an embodiment, referring to Figure 3 and Figure 6 The box body 111 is provided with an air inlet channel 111d extending along the height direction of the box body 111. At least part of the air inlet channel 111d is located in the heat exchange cavity 111a and communicates with the heat exchange cavity 111a through the air passage 111e, that is, the air inlet channel 111d extends into the heat exchange cavity 111a, and the air inlet is arranged at the bottom end of the air inlet channel 111d. The air flow enters the air inlet channel 111d from the air inlet, and then flows into the heat exchange cavity 111a through the air passage 111e. The air inlet channel 111d extending along the height direction of the box body 111 can not only make the air flow flow into the heat exchange cavity 111a from a relatively high position in the heat exchange cavity 111a, but also can diffuse quickly in all directions in the heat exchange cavity 111a after the air flow flows out of the air passage 111e. Therefore, the condensed liquid sprayed into the heat exchange cavity 111a through the spray hole 112c can be in time and sufficient contact with the air flow flowing out of the air passage 111e, and the heat exchange efficiency can be improved.

[0055] In an embodiment, referring to Figure 6 The air passage 111e includes a first air passage 111e1 facing the box cover 112. The region of the box cover 112 facing the first air passage 111e1 forms a condensate water flow guide surface 112d. The air flow flowing out of the first air passage 111e1 is condensed to form condensate water on the condensate water flow guide surface 112d, and the condensate water is guided into the heat exchange cavity 111a through the condensate water flow guide surface 112d.

[0056] Specifically, if the top end of the air inlet channel 111d is set as a closed end, i.e. without the first air passage 111e1, the part of the humid hot air flow entering the air inlet channel 111d will condense to form condensed water after contacting the closed end of the air inlet channel 111d, and the condensed water will flow back into the clothes treatment cavity. Therefore, the first air passage 111e1 can be arranged at the top end of the air inlet channel 111d, and the condensed water guide surface 112d can be arranged at the area of the box cover 112 facing the first air passage 111e1. The part of the humid hot air flow flowing out of the first air passage 111e1 will still condense to form condensed water after contacting the condensed water guide surface 112d, but the condensed water can be guided into the heat exchange cavity 111a through the condensed water guide surface 112d and discharged from the water outlet 111b with the condensed liquid, thereby avoiding the condensed water from dropping into the air inlet channel 111d and flowing back into the clothes treatment cavity as much as possible.

[0057] For example, referring to Figure 6 , the side wall of the air inlet channel 111d has a spacing with the side wall of the heat exchange cavity 111a, that is, the air inlet channel 111d does not contact the side wall of the heat exchange cavity 111a, or the humid hot air flow flowing out of the first air passage 111e1 can diffuse to the periphery of the first air passage 111e1. The condensed water guide surface 112d can be a inclined surface with a high center and a low periphery, and more preferably, the condensed water guide surface 112d can be a substantially conical surface or a circular arc top. The condensed water on the condensed water guide surface 112d can flow into the heat exchange cavity 111a along the edge of the periphery of the condensed water guide surface 112d, thereby improving the flow speed of the condensed water.

[0058] In another embodiment, the condensed water guide surface 112d can also include a horizontal sub-surface and an inclined sub-surface, the inclined sub-surface being arranged around the periphery of the horizontal sub-surface and inclined downward from the side connected to the horizontal sub-surface to the side away from the horizontal sub-surface. Since the humid hot air flow mainly flows into the heat exchange cavity 111a from the edge of the first air passage 111e1, the middle area of the condensed water guide surface 112d can be set as a horizontal surface, and the periphery can be set as an inclined surface.

[0059] In some embodiments, whether the side wall of the air inlet channel 111d has a spacing with the side wall of the heat exchange cavity 111a or not, the condensed water guide surface 112d can be set as an inclined surface inclined from one side to the opposite side.

[0060] In an embodiment, referring to Figure 6The air outlet 111e can further include a second air outlet 111e2 arranged on the sidewall of the air inlet channel 111d, that is, a part of the wet hot air flow flows out from the first air outlet 111e1 at the top of the air inlet channel 111d, and another part of the wet hot air flow flows out from the second air outlet 111e2 on the sidewall of the air inlet channel 111d, so that the rate of the wet hot air flow flowing into the heating cavity can be increased, and the heat exchange efficiency can be improved.

[0061] Exemplarily, referring to Figure 6 , the height of part of the sidewall of the air inlet channel 111d can be higher than that of another part of the sidewall, so that the top end of the air inlet channel 111d can define a second air outlet 111e2 extending along the circumference of the air inlet channel 111d.

[0062] In an embodiment, referring to Figure 3 , Figure 4 and Figure 7 , the box cover 112 includes a cover body 1121 and a baffle 1122, one end of the baffle 1122 is connected with the cover body 1121, and the opposite end of the baffle 1122 extends towards the bottom wall of the heat exchange cavity 111a, and the height of the baffle 1122 can be determined as required, and preferably, the lowest point of the baffle 1122 can be not higher than the lowest point of the air outlet 111e. The baffle 1122 divides the heat exchange cavity 111a into a first sub-cavity 111a1 and a second sub-cavity 111a2, the second sub-cavity 111a2 is located on one side of the first sub-cavity 111a1 in the transverse direction, and the first sub-cavity 111a1 communicates with the second sub-cavity 111a2. The air inlet is located in the first sub-cavity 111a1, that is, at least part of the air inlet channel 111d is located in the first sub-cavity 111a1, and the air outlet 111c is arranged on the sidewall of the second sub-cavity 111a2, and the condensed liquid flow path at least passes through the first sub-cavity 111a1. That is, the baffle 1122 separates the air outlet 111e and the air outlet 111c, that is, the air outlet 111e and the air outlet 111c are located on opposite sides of the baffle 1122, the wet hot air flow flows into the first sub-cavity 111a1 along the air inlet channel 111d, and directly contacts and exchanges heat with the condensed liquid in the first sub-cavity 111a1, and the low-temperature dry air flow formed after heat exchange flows into the second sub-cavity 111a2, and then is discharged through the air outlet 111c.

[0063] The baffle 1122 can block the flow of the wet hot air flow in the heat exchange cavity 111a to a certain extent, that is, the wet hot air flow flowing out from the air outlet 111e needs to bypass the baffle 1122 to flow to the air outlet 111c, rather than directly flowing to the air outlet 111c, which is equivalent to increasing the travel of the wet hot air flow in the heat exchange cavity 111a, so that the wet hot air flow can be fully heat-exchanged, and the condensation and dehumidification effect is further improved.

[0064] In addition, Figure 7 The water outlet 111b is in communication with the first sub-cavity 111a1, that is, the condensed liquid after heat exchange is discharged from the first sub-cavity 111a1 instead of the second sub-cavity 111a2, which means that the low-temperature dry gas flow entering the second sub-cavity 111a2 is separated from the condensed liquid, so as to avoid the water vapor in the condensed liquid from mixing into the low-temperature dry gas flow as much as possible.

[0065] In some embodiments, the water outlet 111b can also be in communication with the second sub-cavity 111a2, which means that the condensed liquid after heat exchange is discharged from the second sub-cavity 111a2.

[0066] In an embodiment, please refer to Figure 3 , Figure 6 and Figure 7 The dehumidifier 10 further comprises at least one partition plate 13 arranged in the first sub-cavity 111a1, and the partition plate 13 extends in the first sub-cavity 111a1 in the bending flow channel 111f from top to bottom.

[0067] Specifically, the partition plate 13 can divide at least two sub-flow channels 111f1 in the first sub-cavity 111a1, and each sub-flow channel 111f1 is in communication in sequence, thereby forming the bending flow channel 111f from top to bottom.

[0068] Please continue to refer to Figure 3 , Figure 6 and Figure 7 The air inlet channel 111d extends into the bending flow channel 111f, that is, the air flow entering the heat exchange cavity 111a from the air passage 111e flows into the bending flow channel 111f. Figure 3 , Figure 6 and Figure 7 The air passage 111e in

[0069] Please continue to refer to Figure 3 , Figure 6 and Figure 7 The spray hole 112c is in communication with the bending flow channel 111f, that is, each spray hole 112c is in communication with the uppermost sub-flow channel 111f1, and the condensed liquid can be sprayed into the bending flow channel 111f.

[0070] The condensate directly contacts the wet hot air flowing along the bending flow channel 111f in the same fluid channel during the flowing process of the condensate along the bending flow channel 111f, the bending flow channel 111f increases the flowing distance of the wet hot air and the condensate in the heat exchange cavity 111a, so that the condensate can fully contact the wet hot air, thereby the condensate and the wet hot air can fully exchange heat in the heat exchange cavity 111a, and the condensation dehumidification effect can be improved.

[0071] In addition, Figure 3 、 Figure 6 and Figure 7 The second sub-cavity 111a2 is in communication with the sub-flow channel 111f1 located at the lowermost layer, that is, the low-temperature dry air flow formed after heat exchange flows into the second sub-cavity 111a2 from the sub-flow channel 111f located at the lowermost layer of the bending flow channel 111f, and then flows out from the air outlet 111c. The water outlet 111b is in communication with the sub-flow channel 111f1 located at the lowermost layer, that is, the condensate after heat exchange directly flows out from the sub-flow channel 111f1 located at the lowermost layer without flowing into the second sub-cavity 111a2, which is equivalent to that the low-temperature dry air flow and the condensate are separated after entering the second sub-cavity 111a2, thereby the water vapor in the condensate can be prevented from mixing into the low-temperature dry air flow as much as possible.

[0072] Further, Figure 7 the water outlet 111b can be arranged on the side of the sub-flow channel 111f1 located at the lowermost layer away from the second sub-cavity 111a2, which is equivalent to that the low-temperature dry air flow and the condensate flow in opposite directions in the sub-flow channel 111f1 located at the lowermost layer, thereby the water vapor in the condensate can be prevented from mixing into the low-temperature dry air flow better.

[0073] In some embodiments, only a part of the spray holes 112c can be in communication with the bending flow channel 111f, for example, another part of the spray holes 112c can be in communication with the region of the heat exchange cavity 111a between the baffle 1122 and the air outlet, which is equivalent to that the air flow flowing out from the bending flow channel 111f can further exchange heat with the condensate sprayed from the spray holes 112c after flowing into the region of the heat exchange cavity 111a between the baffle 1122 and the air outlet, so as to further perform condensation dehumidification.

[0074] The sub-flow channels 111f1 are sequentially in communication to collectively form the bending flow channel 111f extending from top to bottom in various ways, for example, Figure 7 the baffle 1122, the partitions 13 and the side wall of the heat exchange cavity 111a collectively define the sub-flow channels 111f1, that is, the baffle 1122 and the side wall of the heat exchange cavity 111a enclose a containing space, and the partitions 13 divide the containing space into a plurality of sub-flow channels 111f1, Figures 8 to 10Part of the edge of the partition plate 13 is spaced apart from the side wall of the heat exchange cavity 111a, so that the space between them forms a water passage 13a. Part of the edge of the other partition plate 13 is spaced apart from the baffle 1122, so that the space between them also forms a water passage 13a, and each sub-flow passage 111f1 communicates through these water passages 13a in turn. In other embodiments, part of the edge of each partition plate 13 can be spaced apart from the side wall of the heat exchange cavity 111a, so that the space between them forms a water passage 13a.

[0075] In some embodiments, the partition plate 13 can also be spaced apart from the baffle 1122 and / or the side wall of the heat exchange cavity 111a, for example, a water passage 13a can be directly provided on the partition plate 13.

[0076] In other embodiments, part of the edge of the partition plate 13 can be spaced apart from the baffle 1122 and / or the side wall of the heat exchange cavity 111a, and a water passage 13a can be provided on the other partition plate 13.

[0077] Further, referring to Figure 10 At least part of the partition plate 13 can also be provided with a heat exchange member 12, which can be a heat dissipation fin, a heat conducting plate or other member with heat exchange function. That is, each partition plate 13 can be provided with a heat exchange member 12, or only part of the partition plates 13 can be provided with a heat exchange member 12. ​ In some embodiments, the heat exchange member 12 can be provided on only one of the two opposite end faces of the same partition plate 13.

[0078] When the wet hot air flowing along the bent flow passage 111f flows through the heat exchange member 12, the wet hot air can exchange heat with the heat exchange member 12, that is, the heat exchange member 12 and the condensed liquid can jointly condense and dehumidify the wet hot air, and at the same time, the condensed liquid can also exchange heat with the heat exchange member 12 to absorb the heat of the heat exchange member 12, thereby further improving the condensation and dehumidification effect.

[0079] It can be understood that in some embodiments, the heat exchange member 12 can also not be provided on the partition plate 13.

[0080] In an embodiment, the clothes treatment apparatus includes a condensation device having a condensation cavity, an inner circulation path passing through the clothes treatment cavity, the condensation cavity and the air guiding device 30 is formed in the clothes treatment apparatus, and the water outlet 111b communicates with the condensation cavity.

[0081] Similar to the function of the dehumidifier 10, the condensing device is also used to dehumidify and cool the humid hot air flow, but the use scene of the condensing device is different from that of the dehumidifier 10. Specifically, two circulation paths can be provided in the clothes treatment equipment, one is the outer circulation path as described above, in which the fresh air is introduced into the clothes treatment equipment, and the humid hot air flow flowing out of the clothes treatment cavity is dehumidified and condensed by the dehumidifier 10 before being discharged to the surrounding environment, and the other is the inner circulation path, that is, the path in which the air flow circulates in the clothes treatment equipment, which passes through the clothes treatment cavity, the condensing cavity of the condensing device and the air guide device 30. Accordingly, the clothes treatment equipment can be provided with an outer circulation mode in which the air flow flows along the outer circulation path, and an inner circulation mode in which the air flow flows along the inner circulation path.

[0082] In the inner circulation mode, the dry hot air flow is introduced into the clothes treatment cavity through the air inlet of the clothes treatment cavity by the air guide device 30. In the clothes treatment cavity, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs the moisture in the clothes, becomes a humid hot air flow, and flows out of the air outlet of the clothes treatment cavity. The humid hot air flow flows into the condensing device, is dehumidified and condensed by the condensing liquid in the condensing device to form a low-temperature dry air flow, and enters the air guide device 30. The low-temperature dry air flow is heated by the heater in the air guide device 30 to form a dry hot air flow. The dry hot air flow enters the clothes treatment cavity again, and the cycle is repeated to achieve drying of the clothes.

[0083] In the inner circulation mode, the dry hot air flow is introduced into the clothes treatment cavity through the air inlet of the clothes treatment cavity by the air guide device 30. In the clothes treatment cavity, the dry hot air flow flows through the surface of the wet clothes, exchanges heat and moisture with the wet clothes, absorbs the moisture in the clothes, becomes a humid hot air flow, and flows out of the air outlet of the clothes treatment cavity. The humid hot air flow flows into the condensing device, is dehumidified and condensed by the condensing liquid in the condensing device to form a low-temperature dry air flow, and enters the air guide device 30. The low-temperature dry air flow is heated by the heater in the air guide device 30 to form a dry hot air flow. The dry hot air flow enters the clothes treatment cavity again, and the cycle is repeated to achieve drying of the clothes.

[0084] The outer circulation mode mainly uses the fresh air in the environment to dry the clothes in the clothes treatment cavity. Since the humidity of the fresh air is relatively low, the humidity of the hot air flow formed after the fresh air is heated by the heating device is also low. During the process of the hot air flow flowing through the clothes treatment cavity, the heat exchange and mass transfer efficiency can be accelerated, and the drying efficiency can be improved. In addition, the fresh air can also discharge the odor in the clothes treatment cavity to the surrounding environment to play a role in removing odor.

[0085] For the inner circulation mode, on the one hand, the air flow in the inner circulation process can reduce heat loss, reduce energy consumption, improve efficiency, and on the other hand, can also reduce the influence on the indoor environment.

[0086] It can be understood that the laundry treating apparatus is not limited to having both the outer circulation mode and the inner circulation mode, and in some embodiments, the laundry treating apparatus can have only the outer circulation mode without the inner circulation mode.
