Referring to fig. 2 to 6, the heat exchange box 11 has a heat exchange chamber 111a, a water inlet 112a communicating with the heat exchange chamber 111a, a water outlet 111b, an air inlet channel 111d, and an air outlet 111c. The air inlet channel 111d extends along the height direction of the heat exchange box 11, at least part of the area of the air inlet channel 111d extends into the heat exchange cavity 111a, and the top end of the air inlet channel 111d exceeds the height of the air outlet, wherein the exceeding means that the air flows into the heat exchange cavity 111a from a relatively higher position in the heat exchange cavity 111a and flows out from a relatively lower air outlet 111c.

The air flow entering from the air inlet passage 111d is in direct contact with the water flow entering from the water inlet 112a in the heat exchange chamber 111a.

Illustratively, an embodiment of the present application provides a laundry treating apparatus, referring to fig. 1, including a drum assembly 20, an air guiding device 30, and a dehumidifying device 10 according to 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 air inlet is communicated with the air outlet, and the air outlet 111c is communicated with the outside; the air inlet is communicated with the outside through an air guiding device 30.

The laundry treating apparatus may be a dryer, a washing and drying integrated machine, etc., without limitation. The laundry treating apparatus may be a drum-type laundry treating apparatus or a pulsator-type laundry treating apparatus.

The air guiding device 30 is internally provided with a fan and a heating component, the air guiding device 30 can heat external fresh air and then guide the heated fresh air into the clothes processing cavity through the air inlet, and in the clothes processing cavity, dry hot air flows through the surface of wet clothes to perform heat-moisture exchange with the wet clothes, absorb moisture in the clothes, become damp-heat air flow, and the damp-heat air flow flows out from the air outlet of the clothes processing cavity.

The air outlet of the clothes treatment cavity is communicated with the air inlet of the dehumidifying device 10, and the wet and hot air flow flowing out of the air outlet of the clothes treatment cavity enters the dehumidifying device 10 through the air inlet to be condensed and dehumidified to form low-temperature dry air flow, and the low-temperature dry air flow is discharged from the air outlet 111c and enters the surrounding environment.

In one embodiment, the air outlet 111c of the dehumidifying apparatus 10 may be in communication with the detergent box, that is, the low temperature drying air flow is discharged to the surrounding environment through the detergent box, and in some embodiments, the air outlet 111c may also be in direct communication with the outside.

The low temperature dry air flow is a relatively wet and hot air flow, and the temperature of the low temperature dry air flow is lower than that of the wet and hot air flow. The low temperature in the embodiments of the present application may be room temperature.

The dehumidifying device 10 of the embodiment of the present application is provided with the heat exchange box 11 having the heat exchange cavity 111a, the water inlet 112a, the water outlet 111b, the air inlet channel 111d and the air outlet 111c, since the air inlet channel 111d extends along the height direction of the heat exchange box 11 and at least a part of the area of the air inlet channel 111d extends into the heat exchange cavity 111a, and meanwhile, the height of the top end of the air inlet channel 111d exceeds the height of the air outlet, the air flow flowing in from the air inlet channel 111d can enter the heat exchange cavity 111a from a relatively higher position in the heat exchange cavity 111a and then flow to a relatively lower air outlet after diffusing around in the heat exchange cavity 111a relatively fast, and the condensate flowing in from the water inlet 112a into the heat exchange cavity 111a can be fully contacted with the air flow directly in the flowing process, that is, the contact surface between the air flow and the condensate is not only longer, but also the contact surface between the air flow and the condensate is large, and the heat exchange is full, thereby, the condensate and the dehumidifying device 10 can have good condensing effect.

In addition, the dehumidifying apparatus 10 of the embodiment of the present application can be used for condensing and dehumidifying the hot and humid air flow discharged from the laundry treatment chamber of the laundry treatment apparatus, the air flow condensed and dehumidified by the dehumidifying apparatus 10 is discharged through the air outlet 111c and enters the indoor environment, that is, the air flow discharged into the surrounding environment is condensed and dehumidified by the condensing apparatus, so that the indoor temperature and humidity are not significantly affected, the influence on the indoor environment is reduced, and the user experience is improved.

The heat exchange box 11 may have various structural forms, for example, referring to fig. 2 to 6, the heat exchange box 11 may include a box body 111 and a box cover 112 that covers the top of the box body 111, the box cover 112 is provided with a water inlet 112a, the box body 111 is provided with a heat exchange cavity 111a, a water outlet 111b, an air inlet channel 111d and an air outlet 111c, that is, the heat exchange box 11 may be formed by the box body 111 and the box cover 112, and in some embodiments, the heat exchange box 11 may not be formed by the box body 111 and the box cover 112, for example, the heat exchange box 11 may be an integral structure or may be formed by assembling a plurality of shells.

In addition, referring to fig. 5 to 7, the cover 112 may be provided with a water passing chamber 112b having a plurality of spray holes 112c, the water inlet 112a is in communication with the water passing chamber 112b, the heat exchanging chamber 111a is in communication with each spray hole 112c, that is, condensate enters the water passing chamber 112b from the water inlet 112a and then is sprayed into the heat exchanging chamber 111a through the spray holes 112c, thereby enabling the condensate to be in full contact with the wet and hot air flow flowing into the heat exchanging chamber 111a, enabling full heat exchange between the condensate and the wet and hot air flow, and further improving the condensation dehumidifying effect.

In some embodiments, the lid 112 may not be provided with the water chamber 112b.

Referring to fig. 5 and 7, the top end of the air inlet channel 111d has a gas passing opening 111e, and the air flow entering the air inlet channel 111d flows into the heat exchange chamber 111a through the gas passing opening 111 e. The air passing port 111e may be disposed in various manners, for example, referring to fig. 5 and 7, the air passing port 111e may include a first air passing port 111e1 facing a top wall of the heat exchange cavity 111a, that is, an air flow may flow into the heat exchange cavity 111a toward the top wall.

Further, referring to fig. 5 and 7, a region of the top wall of the heat exchange cavity 111a facing the first air passing opening 111e1 may form a condensate water guiding surface 112d, and the air flow flowing out from the first air passing opening 111e1 is condensed on the condensate water guiding surface 112d to form condensate water, and the condensate water is guided into the heat exchange cavity 111a through the condensate water guiding surface 112 d.

Specifically, if the top end of the air intake passage 111d is provided as the closed end, i.e., the first air passing opening 111e1 is not provided, a portion of the hot and humid air flow entering the air intake passage 111d is condensed to form condensed water after contacting the closed end of the air intake passage 111d, and the condensed water flows back into the laundry treating chamber along the air intake passage 111d, so that the first air passing opening 111e1 may be provided at the top end of the air intake passage 111d, and at the same time, the condensed water guide surface 112d may be provided at the top wall of the heat exchanging chamber 111a toward the area of the first air passing opening 111e1, and a portion of the hot and humid air flow flowing out from the first air passing opening 111e1 may still be condensed to form condensed water after contacting the condensed water guide surface 112d, but the condensed water may be introduced into the heat exchanging chamber 111a through the condensed water guide surface 112d and discharged from the water outlet 111b along with the condensed water, whereby dripping into the air intake passage 111d and flowing back into the laundry treating chamber may be prevented as much as possible.

For example, referring to fig. 5, the sidewall of the air inlet channel 111d and the sidewall of the heat exchange cavity 111a have a space therebetween, that is, the air inlet channel 111d is not in contact with the sidewall of the heat exchange cavity 111a, the condensate water guiding surface 112d may be an inclined surface with a high center and a low circumference, and more preferably, the condensate water guiding surface 112d may be a substantially conical surface or a circular arc top. The condensed water on the condensed water guide surface 112d may flow into the heat exchange chamber 111a along the edges around the condensed water guide surface 112d, whereby the guide speed of the condensed water may be increased.

In another embodiment, the condensate guiding surface 112d may also include a horizontal sub-surface and an inclined sub-surface, wherein the inclined sub-surface is disposed around the horizontal sub-surface, and the inclined sub-surface is inclined downward from the side connected with the horizontal sub-surface to the side far from the horizontal sub-surface. Since the flow of the wet and hot air mainly flows into the heat exchange chamber 111a from the edge of the first air passing opening 111e1, the middle region of the condensate water guiding surface 112d may be set to be a horizontal plane, and the periphery may be set to be an inclined plane.

In some embodiments, the condensate water deflector 112d may be provided as an inclined surface inclined from one side to the opposite side, regardless of whether there is a space between the side wall of the air inlet passage 111d and the side wall of the heat exchange chamber 111a.

In an embodiment, referring to fig. 5, the air passing port 111e may further include a second air passing port 111e2, where the second air passing port 111e2 is disposed on a side wall of the air inlet channel 111d, that is, a part of the hot and humid air flows out from the first air passing port 111e1 on the top of the air inlet channel 111d, and another part of the hot and humid air flows out from the second air passing port 111e2 on the side wall of the air inlet channel 111d, so that the rate of flowing the hot and humid air into the heating cavity can be increased, and the heat exchange efficiency can be further improved.

For example, referring to fig. 5, a portion of the side wall of the intake passage 111d may have a height higher than that of another portion of the side wall such that the tip end of the intake passage 111d may define a second gas passing opening 111e2 extending in the circumferential direction of the intake passage 111 d.

In an embodiment, referring to fig. 3 and 5 to 7, the dehumidifying device 10 includes a baffle 14, the baffle 14 separates a first sub-chamber 111a1 and a second sub-chamber 111a2 in the heat exchange chamber 111a, the second sub-chamber 111a2 is located at one lateral side of the first sub-chamber 111a, and the first sub-chamber 111a1 is communicated with the second sub-chamber 111a2. At least a part of the air inlet channel 111d extends into the first subchamber 111a1, which is equivalent to that the air passing opening 111e is positioned in the first subchamber 111a1, the air outlet 111c is arranged on the side wall of the second subchamber 111a2, the baffle 14 separates the air passing opening 111e from the air outlet 111c, that is, the air passing opening 111e and the air outlet 111c are respectively positioned at two opposite sides of the baffle 14, and a condensate flow path formed between the water inlet 112a and the water outlet 111b at least passes through the first subchamber 111a1. That is, the wet and hot air flows into the first sub-chamber 111a1 along the air inlet channel 111d, and performs direct contact heat exchange with condensate in the first sub-chamber 111a1, and the low temperature dry air flow formed after the heat exchange flows into the second sub-chamber 111a2 and is discharged through the air outlet 111c.

The baffle 14 shown in fig. 3 is connected to the box cover 112, that is, the baffle 14 is disposed on the box cover 112, and when the box cover 112 is disposed on the box body 111, the baffle 14 extends into the heat exchange chamber 111a and separates the first sub-chamber 111a1 and the second sub-chamber 111a2. In some embodiments, the baffle 14 may also be disposed directly within the heat exchange cavity 111a without being connected to the lid 112.

The baffle 14 can play a certain role in blocking the flow of the hot and humid air flow in the heat exchange cavity 111a, that is, the hot and humid air flow flowing out from the air passing opening 111e needs to bypass the baffle 14 to flow to the air outlet 111c but not directly flow to the air outlet 111c, which is equivalent to increasing the travel of the hot and humid air flow in the heat exchange cavity 111a, thereby ensuring that the hot and humid air flow can exchange heat sufficiently and further improving the condensation and dehumidification effects.

In addition, the water outlet 111b shown in fig. 6 is in communication with the first subchamber 111a1, that is, the condensate after heat exchange is discharged from the first subchamber 111a1, but not from the second subchamber 111a2, which corresponds to separation of the low-temperature drying air flow entering the second subchamber 111a2 from the condensate, whereby the water vapor in the condensate can be prevented from being mixed into the low-temperature drying air flow as much as possible.

In an embodiment, referring to fig. 8 to 10, at least two sub-channels 111f1 layered along the height direction of the heat exchange box 11 are formed in the heat exchange cavity 111a, and each sub-channel 111f1 is sequentially connected to form a bent channel 111f extending from top to bottom.

Specifically, the air inlet channel 111d and the water inlet 112a are respectively communicated with the bending flow channel 111f, the air flow entering the heat exchange cavity 111a from the air inlet channel 111d flows into the bending flow channel 111f, the condensate entering the heat exchange cavity 111a from the water inlet 112a also flows into the bending flow channel 111f, that is, the condensate directly contacts with the wet and hot air flow flowing along the bending flow channel 111f in the same fluid channel for heat exchange in the process of flowing along the bending flow channel 111f, and the bending flow channel 111f increases the travel of the wet and hot air flow and the condensate flowing in the heat exchange cavity 111a so that the condensate can fully contact with the wet and hot air flow, thereby enabling the condensate and the wet and hot air flow to fully exchange heat in the heat exchange cavity 111a and further improving the condensation and dehumidification effects.

The air inlet passage 111d and the water inlet 112a may communicate with the sub-flow passage 111f1 of any one layer, respectively, and more preferably, the air inlet passage 111d and the water inlet 112a may communicate with the sub-flow passage 111f1 located at the uppermost layer, respectively. That is, the wet and hot air flow enters the uppermost sub-flow passage 111f1 from the air inlet passage 111d, flows along the folded flow passage 111f to the lowermost sub-flow passage 111f1, then flows out through the air outlet 111c, and the condensate enters the uppermost sub-flow passage 111f1 from the water inlet 112a, flows along the folded flow passage 111f to the lowermost sub-flow passage 111f1, and then flows out through the water outlet 111 b.

As for the dehumidifying apparatus 10 provided with the baffle 14, at least one partition 13 may be provided in the first sub-chamber 111a1, and the partition 13 may divide the first sub-chamber 111a1 into the bent flow paths 111f extending from top to bottom, as shown in fig. 8 to 10. That is, each sub-flow passage 111f1 may be defined by the baffle plate 14, the partition plate 13, and the side wall of the heat exchange chamber 111a together.

The water outlet 111b shown in fig. 10 is connected to the sub-flow channel 111f1 located at the lowest layer, that is, the condensate after heat exchange flows to the sub-flow channel 111f1 located at the lowest layer, and then directly flows out of the sub-flow channel 111f1 located at the lowest layer without flowing into the second sub-chamber 111a2, which corresponds to separation of the low-temperature dry air flow entering the second sub-chamber 111a2 from the condensate, so that it is possible to avoid water vapor in the condensate from being mixed into the low-temperature dry air flow as much as possible.

Further, referring to fig. 10, the water outlet 111b may be disposed at a side of the sub-flow channel 111f1 located at the lowest layer facing away from the second sub-cavity 111a2, which is equivalent to that the low temperature drying air flow and the condensate flow in two opposite directions in the sub-flow channel 111f1 located at the lowest layer, so that water vapor in the condensate can be better prevented from being mixed into the low temperature drying air flow.

In some embodiments, the water outlet 111b may also be in communication with the second subchamber 111a2, and the condensate corresponding to the heat exchange flows into the second subchamber 111a2 from the subchannel 111f1 located at the lowest layer of the bent channel 111f, and then flows out of the water outlet 111 b.

Referring to fig. 8 and 10, each sub-runner 111f1 may be sequentially connected through a water passing port 13a, and the water passing port 13a may be formed in various manners, for example, referring to fig. 8 and 10, a part of the edges of a part of the partition plates 13 are spaced from the side wall of the heat exchange cavity 111a, so that the water passing port 13a is formed at the interval between the two, and a part of the edges of the other part of the partition plates 13 are spaced from the baffle plate 14, so that the water passing port 13a is also formed at the interval between the two. In other embodiments, part of the edge of each partition 13 may be spaced from the side wall of the heat exchange chamber 111a, so that the water passing port 13a is formed at the interval between the two.

In some embodiments, the baffle 13 may be disposed without being spaced apart from the sidewall of the baffle 14 and/or the heat exchange chamber 111a, for example, the water passing port 13a may be disposed directly on the baffle 13.

In other embodiments, a part of the edges of the partition 13 may be spaced apart from the baffle 14 and/or the side wall of the heat exchange chamber 111a, and the water passing port 13a may be provided in the other part of the partition 13.

In some embodiments, the baffle 14 may not be provided, for example, the plurality of partitions 13 may directly partition the plurality of sub-channels 111f1 in the heat exchange cavity 111a.

Further, referring to fig. 9 and 10, for the box cover 112 provided with the water passing cavity 112b, each spraying hole 112c may be communicated with the sub-flow channel 111f1 located at the uppermost layer, that is, the condensate may be sprayed into the sub-flow channel 111f1 located at the uppermost layer through the spraying holes 112c, in some embodiments, a part of the spraying holes 112c may be communicated with the sub-flow channel 111f1 located at the uppermost layer, another part of the spraying holes 112c may be communicated with the second sub-cavity 111a2, which corresponds to that after the air flow flowing out from the bent flow channel 111f flows into the second sub-cavity 111a2, heat exchange may be performed between the condensate sprayed from the spraying holes 112c in the second sub-cavity 111a2.

In some embodiments, for the cap 112 where the water passing chamber 112b is not provided, the water inlet 112a may directly communicate with the sub flow passage 111f1 positioned at the uppermost layer.

In an embodiment, referring to fig. 11 to 13, heat exchange elements 12 may be disposed in at least a portion of the sub-flow channels 111f1, that is, the heat exchange elements 12 may be disposed in each of the sub-flow channels 111f1, or the heat exchange elements 12 may be disposed in only a portion of the sub-flow channels 111f1. The heat exchanging member 12 may be a member having a heat exchanging function such as a heat radiating fin or a heat conducting plate.

When the hot and humid air flowing along the bending flow channel 111f flows through the heat exchange member 12, the hot and humid air can exchange heat with the heat exchange member 12, that is, the heat exchange member 12 and the condensate can jointly condense and dehumidify the hot and humid air, and at the same time, the condensate can exchange heat with the heat exchange member 12 to absorb heat of the heat exchange member 12, so that the condensation and dehumidification effects can be further improved.

The heat exchange member 12 may be disposed in the sub-flow channel 111f1 in various manners, for example, referring to fig. 11 and 13, the heat exchange member 12 may be disposed on at least a portion of the partition 13, in fig. 13, the heat exchange member 12 may be disposed on two opposite end surfaces of the same partition 13, and in some embodiments, the heat exchange member 12 may be disposed on only one of the end surfaces.

It will be appreciated that in some embodiments, the heat exchange member 12 may not be disposed within the sub-flow channel 111f1.

In some embodiments, the heat exchange cavity 111a may not have a bent flow channel 111f.

In one embodiment, the laundry treating apparatus includes a condensing device having a condensing chamber, an internal circulation path passing through the laundry treating chamber, the condensing chamber and the air guiding device 30 is formed in the laundry treating apparatus, and the water outlet 111b communicates with the condensing chamber.

Similar to the function of the dehumidifying apparatus 10, the condensing apparatus is also used for dehumidifying and cooling the hot and humid air flow, but the condensing apparatus is different from the dehumidifying apparatus 10 in use. Specifically, two circulation paths may be provided in the laundry treating apparatus, one being the aforementioned external circulation path for introducing fresh air into the laundry treating apparatus, condensing and dehumidifying the hot and humid air flow flowing out of the laundry treating chamber by the dehumidifying device 10, and then discharging the same to the surrounding environment, and the other being the internal circulation path through the laundry treating chamber, the condensing chamber of the condensing device and the air guiding device 30, that is, the path through which the air flow circulates in the laundry treating apparatus. Accordingly, the laundry treating apparatus may set 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.

In the internal circulation mode, the air guide device 30 guides the hot dry air to the clothes treatment cavity through the air inlet of the clothes treatment cavity, in the clothes treatment cavity, the hot dry air flows through the surface of wet clothes, carries out heat-moisture exchange with the wet clothes, absorbs moisture in the clothes, becomes hot and humid air flow, and flows out of the air outlet of the clothes treatment cavity, then flows into the condensing device, the hot and humid air flow forms low-temperature dry air flow after being condensed and dehumidified by condensate in the condensing device, and the low-temperature dry air flow enters the air guide device 30 and forms dry hot air flow after being heated by the heater in the air guide device 30. The hot drying air flow enters the clothes treating cavity again, and the clothes treating cavity is circularly operated in such a way to realize the drying of clothes.

The water outlet 111b of the dehumidifier 10 is communicated with the condensation chamber of the condenser, that is, the condenser and the dehumidifier 10 may share a water path, in the external circulation mode, condensate after heat exchange with the hot and humid air flow in the dehumidifier 10 flows into the condenser through the water outlet 111b of the dehumidifier 10 and is discharged through the condenser, in the internal circulation mode, condensate flows through the dehumidifier 10 and flows into the condenser from the water outlet 111b of the dehumidifier 10 to exchange heat with the hot and humid air flow, and condensate after heat exchange is discharged from the condenser.

The external circulation mode mainly utilizes fresh air in the environment to dry clothes in the clothes treatment cavity, and because the humidity of the fresh air is relatively low, the humidity of hot air flow formed after the fresh air is heated by the heating device is also low, and the heat exchange quality-changing efficiency can be quickened and the clothes drying efficiency is improved in the process that the hot air flows through the clothes treatment cavity. In addition, the fresh air can also discharge peculiar smell in the clothes treatment cavity to the surrounding environment so as to play a role in deodorizing.

And for the internal circulation mode, on one hand, the air flow can reduce heat loss in the internal circulation process, reduce energy consumption and improve efficiency, and on the other hand, the influence on the indoor environment can be reduced.

It is to 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 may have only the outer circulation mode and no inner circulation mode.
