The box body 11 is provided with a water outlet 10c, and the condensate flows along the condensate flow path after entering the heat exchange device 10 and then is guided out of the heat exchange device 10 through the water outlet 10 c.

The specific location of the water outlet 10c is not limited herein, and for example, referring to fig. 3, the water outlet 10c is disposed on the sidewall of the box body 11. In other embodiments, the water outlet 10c is disposed on the bottom wall of the box 11.

Referring to fig. 3 and 4, the box 11 has an air inlet 10d and an air outlet 10e, an air flow path is formed between the air inlet 10d and the air outlet 10e, and the air flow enters the heat exchange device 10 from the air inlet 10d, flows along the air flow path, and then is guided out of the heat exchange device 10 through the air outlet 10 e.

Exemplarily, referring to fig. 3 and 4, the box 11 includes a body 111 and an intake pillar 112 at least partially disposed in the body 111, the body 111 defines a heat exchange chamber 10a between the body 111 and the intake pillar 112, an intake passage 112a having an intake port 10d is formed in the intake pillar 112, and the intake passage 112a communicates with the heat exchange chamber 10a through the intake port. In this embodiment, the air flow enters the air inlet passage 112a inside the air inlet cylinder 112 from the air inlet 10d, and then enters the heat exchange chamber 10a through the air passing opening of the air inlet passage 112 a. Wherein the intake passage 112a constitutes a partial airflow flow path.

It should be noted that the intake cylinder 112 at least partially disposed in the body 111 means that, in some embodiments, the intake cylinders 112 are all disposed in the body 111, that is, the intake cylinder 112 is not exposed to the body 111. In other embodiments, the intake cylinder 112 is partially disposed in the body 111, and is partially exposed out of the body 111, and the portion exposed out of the body 111 may be connected to the cylinder assembly.

It can be understood that the heat exchange cavity 10a is formed in the heat exchange device 10, thereby the heat exchange cavity 10a between the body 111 and the intake column 112 is defined in the body 111, that is, the heat exchange cavity 10a is defined between the intake column 112 and the body 111 in the body 111, that is, the heat exchange cavity 10a is located on the peripheral side of the intake column 112.

Illustratively, referring to fig. 2, the heat exchanging member 20 is disposed on the circumferential side of the intake cylinder 112.

The condensate from the condensate flow path enters the heat exchange cavity 10a located on the periphery of the air inlet column barrel 112 and can exchange heat with the heat exchange piece 20 on the periphery of the air inlet column barrel 112, namely, the temperature of the heat exchange piece 20 can be reduced, and after the damp and hot air flows through the air vent of the air inlet channel 112a and enters the heat exchange cavity 10a, the damp and hot air can contact the heat exchange piece 20 on the periphery of the air inlet column barrel 112 and exchange heat, so that the water vapor in the damp and hot air is condensed and separated out to form low-temperature and low-humidity air flow, therefore, the heat exchange efficiency between the condensate and the air flow in the heat exchange device 10 is improved by arranging the heat exchange piece 20 in the heat exchange cavity 10a, and the dehumidification efficiency of the damp and hot air flow is further improved.

It can be understood that, by arranging the heat exchanging part 20 on the peripheral side of the air inlet column 112, the condensate and the air flow can both contact the heat exchanging part 20 and exchange heat in the flowing process, and further, the heat exchanging efficiency between the condensate and the air flow is improved.

The specific structural form and the arrangement form of the heat exchanging member 20 are not limited herein, as long as the condensate and the airflow can both contact the heat exchanging member 20 in the heat exchanging cavity 10a and exchange heat.

For example, referring to fig. 2, the heat exchanging member 20 includes a plurality of heat exchanging fins 21, and each of the heat exchanging fins 21 is disposed around the periphery of the intake cylinder 112. Through setting up a plurality of heat transfer fins 21, increase the area of contact of condensate and air current and heat transfer fins 21 to the heat exchange efficiency between condensate and the air current has been improved.

Sub-channels are formed among the heat exchange fins 21, the air inlet column 112 and the body 111, and among the adjacent heat exchange fins 21, and the condensate and the airflow can exchange heat with the heat exchange fins 21 when flowing through the sub-channels.

The shape of each heat exchange fin 21 is not limited herein, and each heat exchange fin 21 is arc-shaped, for example, each sub-flow passage is also arc-shaped, and the arc-shaped flow passage can reduce the flow resistance of the condensate and the airflow in the heat exchange cavity 10a and can prevent turbulence of the airflow.

It should be noted that the specific arrangement form of each heat exchange fin 21 is not limited herein, and in some embodiments, each heat exchange fin 21 is arranged side by side. In other embodiments, the heat exchanging fins 21 are staggered.

The material of each heat exchange fin 21 is not limited herein, and for example, the material of the heat exchange fin 21 is aluminum, which can improve the heat exchange effect between the heat exchange fin 21 and the condensate and the airflow.

For example, referring to fig. 2, the heat exchange member 20 includes a connection plate 22 disposed between the body 111 and the intake column 112, and each heat exchange fin 21 is disposed on the connection plate 22.

By arranging the connecting plate 22 between the body 111 and the air inlet column casing 112, each heat exchange fin 21 is arranged on the connecting plate 22, and the connection stability of the heat exchange fins 21 can be improved while the arrangement of each heat exchange fin 21 is facilitated.

Specifically, the connecting plate 22 is disposed approximately perpendicular to the center line of the air inlet column 112, and each heat exchange fin 21 is disposed approximately perpendicular to the connecting plate 22 and located between the connecting plate 22 and the box cover 12, so that the condensate flowing into the heat exchange cavity 10a through the water inlet 10b is fully contacted with each heat exchange fin 21, and the air flowing into the heat exchange cavity 10a through the air inlet can be fully contacted with each heat exchange fin 21.

Wherein, the material of connecting plate 22 does not do the restriction here, and exemplarily, the material of connecting plate 22 is aluminium, when guaranteeing that connecting plate 22 has certain structural strength, can also improve the heat transfer effect of connecting plate 22 with condensate and air current.

In some embodiments, the connecting plate 22 is an annular plate annularly disposed between the body 111 and the intake cylinder 112, which further improves the structural strength of the connecting plate 22, and thus the connection strength of the heat exchange fins 21. In other embodiments, the connecting plate 22 is an arc plate with a plurality of spacers arranged between the body 111 and the inlet cylinder 112, i.e. there is a gap between the arc plates.

Referring to fig. 4, the air inlet 10d is disposed at a first end of the air inlet channel 112a, and the air outlet of the cylinder assembly is communicated with the air inlet 10d of the air inlet channel 112a, so that the air discharged from the cylinder assembly flows through the air inlet 10d into the air inlet channel 112 a.

Referring to FIG. 3, the air inlets include a first air inlet 112b, and the first air inlet 112b is disposed at a second end of the air inlet passage 112 a. The air flow in the air inlet channel 112a can flow to the heat exchange cavity 10a through the first air passing opening 112b, and then the heat exchange is performed in the heat exchange cavity 10 a.

It should be noted that, since the air flow can flow to the heat exchange chamber 10a through the first air passing opening 112b at the second end of the air inlet passage 112a, a gap is required between the box cover 12 and the second end of the air inlet column 112, and the air flow can flow to the heat exchange chamber 10a at least through the gap.

Referring to fig. 3, the air inlets include a second air inlet 112c, and the second air inlet 112c is disposed on the sidewall of the air inlet pillar 112. The air flow in the air inlet channel 112a can flow to the heat exchange cavity 10a through the second air passing opening 112c, and then the heat exchange is performed in the heat exchange cavity 10 a.

The number of the second air passing ports 112c is multiple, and each of the second air passing ports 112c is disposed on the sidewall of the intake trunk 112 and is located at one end of the intake trunk 112 close to the first air passing port 112 b.

For example, referring to fig. 5, the box cover 12 has a water passing cavity communicated with the water inlet 10b, and a plurality of spraying holes 12a communicated with the heat exchange cavity 10a are formed on the bottom wall of the water passing cavity. That is to say, the condensate flows into the water cavity through water inlet 10b after, flows to heat transfer chamber 10a through spraying hole 12a again, through forming spraying hole 12a on the diapire to make the condensate divide into the less fluid of stranded entering heat transfer chamber 10a, thereby make the condensate fully contact with each heat transfer fin 21, and then improved the heat exchange efficiency of condensate with each heat transfer fin 21, simultaneously, the setting of spraying hole 12a can control the flow that gets into the condensate in heat transfer chamber 10a, can save the quantity of condensate.

In order to improve the heat exchange efficiency of the condensate and each heat exchange fin 21, each spray hole 12a is formed in the bottom wall of the water passing cavity above each heat exchange fin 21, that is, the condensate can directly contact each heat exchange fin 21 when flowing to the heat exchange cavity 10a through the spray holes 12a, and the situation that the condensate does not contact the heat exchange fins 21 when flowing to the heat exchange cavity 10a is reduced.

In some embodiments, referring to fig. 5, the box cover 12 includes a cover body 121 and a water baffle 123, the peripheral side of the cover body 121 is folded toward the box body 11 to form a surrounding plate, the surrounding plate is connected to the water baffle 123, the water baffle 123 and the cover body 121 together define a water passing cavity, and each spraying hole 12a is formed on the water baffle 123.

In other embodiments, the box cover 12 includes a cover body 121 and a water blocking member, the water blocking member is recessed in the middle to form a water blocking groove, the upper end of the water blocking member is open, each spraying hole 12a is formed on the bottom wall of the water blocking groove, and the cover body 121 is disposed at the open position of the water blocking member and defines a water passing cavity together with the water blocking member.

It can be understood that, since the box body 11 includes the body 111 and the air inlet cylinder 112 disposed in the body 111, the heat exchange cavity 10a is defined between the body 111 and the air inlet cylinder 112, the air inlet passage 112a is formed inside the air inlet cylinder 112, and in order to prevent condensate from flowing into the air inlet passage 112a, the shower holes 12a are not disposed in the bottom wall area of the water passing cavity above the air inlet passage 112a, and the shower holes 12a are formed in the bottom wall area of the water passing cavity above the heat exchange cavity 10 a.

The specific arrangement of the spray holes 12a is not limited herein, and the spray holes 12a are arranged like a shower structure, for example.

The specific installation direction of the intake cylinder 112 is not limited herein, for example, referring to fig. 3, the intake cylinder 112 is installed along the height direction of the main body 111, that is, the air inlet 10d is installed at the bottom of the intake cylinder 112, and the air flow enters the air inlet channel 112a through the air inlet 10d at the bottom.

Referring to fig. 5, the air inlets include a first air inlet 112b disposed at the top end of the air inlet channel 112a, a condensed water guiding surface 12b is formed in a region where the bottom wall of the water passing cavity faces the first air inlet 112b, the air flowing out of the first air inlet 112b is condensed on the condensed water guiding surface 12b to form condensed water, and the condensed water is guided into the heat exchange cavity 10a through the condensed water guiding surface 12 b.

Specifically, a part of the damp and hot air flow discharged from the clothes treatment cavity enters the heat exchange cavity 10a through the first air passing port 112b of the air inlet channel 112a, when the damp and hot air flow contacts with the bottom wall surface of the water passing cavity, the damp and hot air flow is condensed on the bottom wall surface of the water passing cavity to form condensed water, in order to avoid the condensed water from dripping into the air inlet channel 112a and flowing back into the clothes treatment cavity along the air inlet channel 112a as much as possible, a condensed water guide surface 12b can be formed in a region of the bottom wall of the water passing cavity facing the first air passing port 112b, and when the damp and hot air flow flowing out from the first air passing port 112b is condensed on the condensed water guide surface 12b to form condensed water, the condensed water can be guided into the heat exchange cavity 10a through the condensed water guide surface 12b and discharged from the water outlet 10c along with the condensed water.

The specific structure of the condensed water guiding surface 12b is not limited herein, as long as the condensed water can be guided into the heat exchange cavity 10a through the condensed water guiding surface 12b, for example, the condensed water guiding surface 12b may be an inclined surface with a high center and low periphery, that is, the condensed water guiding surface 12b is in an expansion trend from top to bottom. More preferably, the condensed water guide surface 12b may be substantially a conical surface.

The baffle 122 is used for playing certain effect of blockking to the flow of damp and hot air current in heat transfer chamber 10a, that is to say, the damp and hot air current that flows out from the air-passing mouth can not directly flow to air outlet 10e under the blockking of baffle 122, has increased the stroke of damp and hot air current in heat transfer chamber 10a in other words, from this, can ensure that the hot air current of moisturizing can abundant heat transfer, and then has further improved condensation dehumidification effect.

It will be appreciated that the baffle 122 serves to provide some resistance to the flow of the hot humid air stream within the heat exchange chamber 10a, such that the lowest point of the baffle 122 is no higher than the lowest point of the air passing opening.

In one embodiment, referring to fig. 5, the box cover 12 has a water passing cavity communicated with the water inlet 10b, a plurality of spraying holes 12a communicated with the heat exchanging cavity 10a are formed on the bottom wall of the water passing cavity, and the spraying holes 12a are distributed on both sides of the baffle 122. It can be understood that the condensation dehumidification effect on the hot and humid air flow can be improved by increasing the distribution area of the spray holes 12 a.

In an embodiment, referring to fig. 2, heat exchange fins 21 are distributed on both sides of the baffle 122, so that the condensate is in full contact with each heat exchange fin 21, thereby improving the heat exchange efficiency between the condensate and each heat exchange fin 21, and further improving the condensation and dehumidification effect on the damp and hot airflow.

In addition, the side of the inlet cylinder 112 facing the air outlet 10e may not be provided with the second air passing opening 112c, that is, the second air passing opening 112c is not directly opposite to the position of the air outlet 10e, thereby increasing the stroke of the hot humid air in the heat exchange chamber 10 a.

In one embodiment, the clothes treatment apparatus includes a condensing device having a condensing chamber, an internal circulation path is formed in the clothes treatment apparatus through the clothes treatment chamber, the condensing chamber and the air guide device, and the water outlet 10c is communicated with the condensing chamber.

Similar to the function of the dehumidifier, the condensing device is also used for dehumidifying and cooling the humid and hot airflow, but the use scene of the condensing device is different from that of the dehumidifier. Specifically, two circulation paths may be provided in the clothes treatment apparatus, one being the aforementioned external circulation path for introducing fresh air into the clothes treatment apparatus, condensing and dehumidifying the hot and humid air flowing out of the clothes treatment chamber by the dehumidifier, and then discharging the hot and humid air to the surrounding environment, and the other being the internal circulation path passing through the clothes treatment chamber, the condensation chamber of the condensing device, and the air guide device, that is, the path along which the air flows in the clothes treatment apparatus. Accordingly, the laundry treating apparatus may set an external circulation mode in which the air flow flows along the external circulation path and an internal circulation mode in which the air flow flows along the internal circulation path.

In the internal circulation mode, the air guide device guides dry hot air into the clothes treatment cavity through an air inlet of the clothes treatment cavity, in the clothes treatment cavity, the dry hot air flows through the surface of wet clothes to perform heat and humidity exchange with the wet clothes to absorb moisture in the clothes and change the moisture into wet hot air, the wet hot air flows out of an air outlet of the clothes treatment cavity and then flows into the condensing device, the wet hot air flows through condensate in the condensing device to be condensed and dehumidified to form low-temperature dry air flow, the low-temperature dry air flow enters the air guide device, and the low-temperature dry air flow is heated by a heater in the air guide device to form the dry hot air flow. The hot drying air flow enters the clothes treatment cavity again, and the circulation is carried out, so as to realize the drying of the clothes.

The water outlet 10c of the dehumidifier is communicated with the condensation cavity of the condensation device, that is, the condensation device and the dehumidifier may share a water path, in the external circulation mode, the condensate after heat exchange with the humid and hot airflow in the dehumidifier flows into the condensation device through the water outlet 10c of the dehumidifier and is discharged through the condensation device, in the internal circulation mode, the condensate flows through the dehumidifier and flows into the condensation device from the water outlet 10c of the dehumidifier to exchange heat with the humid and hot airflow, and the condensate after heat exchange is discharged from the condensation device.

The outer circulation mode is mainly that the new trend in the environment comes to carry out the drying to the clothing in the clothing processing chamber, because the humidity of new trend is lower relatively, so, the humidity of the hot air current that the new trend formed after heating device heating is also lower, and at the in-process that the hot air current flows through the clothing processing chamber, can accelerate heat transfer and trade matter efficiency, promote the efficiency of drying. In addition, the fresh air can also discharge peculiar smell in the clothes processing cavity to the ambient environment so as to play a role in removing the peculiar smell.

And for the internal circulation mode, on one hand, the air flow can reduce heat loss, reduce energy consumption and improve efficiency in the internal circulation process, and on the other hand, the influence on the indoor environment can also 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 without the inner circulation mode.
