Description

Technical Field

[0001] The present invention relates to the technical field of drying for clothing care, and particularly relates to a direct-discharge fresh air laundry device. Background Art

[0002] During the laundry process of existing drum washing machines, the entire system is a closed system. Sometimes there will be an odor after washing clothes, or if the clothes are not dried in time after washing and the washing machine is opened after a long time, there will be an odor on the clothes.

[0003] Moreover, if the high-temperature and high-humidity gas in the inner drum of the laundry device is directly discharged from the inner drum to the room, it will cause the humidity and temperature of the indoor air to be too high.

[0055] Next, the present invention will be further described in combination with the accompanying drawings and specific implementation manners.

It should be understood that terms such as "having", "including" and "comprising" used herein do not preclude the presence or addition of one or more other elements or their combinations.

[0056] Example 1:

[0057] Refer to Figures 1 - 8 、 Figure 14 、 Figure 15 The present invention also provides a direct - discharge fresh - air laundry device, including: a box body, an inner cylinder 31, an outer cylinder 32, a fresh - air duct 1, an exhaust duct 2, and a heat - exchange component 10.

[0058] The box body constitutes the basic external structure of the direct - discharge fresh - air laundry device.

[0059] The inner cylinder 31 and the outer cylinder 32 are arranged inside the box body. The inner cylinder 31 is used to accommodate the clothes to be dried. The inner cylinder 31 is arranged in the outer cylinder 32 and is communicated with the outer cylinder 32 through the holes (not shown in the figure) on the inner cylinder 31. The humid and hot air in the inner cylinder 31 can enter the outer cylinder 32. An exhaust inlet is provided on the outer cylinder 32.

[0060] The fresh - air duct 1, one end of the fresh - air duct 1 is a fresh - air inlet arranged on the front panel or the upper top panel of the box body, that is, one end of the fresh - air duct 1 is communicated with the external fresh air, and the air outside the box enters the fresh - air duct through the fresh - air inlet. The other end of the fresh - air duct 1 is communicated with the inner cylinder 31 of the laundry device to introduce the external fresh air into the inner cylinder 31 of the laundry device.

[0061] The exhaust duct 2, one end of the exhaust duct 2 is an exhaust inlet arranged on the outer cylinder, and the other end is communicated with the air - duct structure 122 of the air - outlet module 12; the humid and hot air in the inner cylinder of the laundry device first enters the outer cylinder 32 through the holes on the inner cylinder 31, and the humid and hot air in the outer cylinder 32 enters the exhaust duct 2 from the exhaust inlet and enters the air - outlet module 12 through the exhaust duct 2.

[0062] The circulation duct 5, one end of the circulation duct 5 is a ventilation port arranged on the outer cylinder 32, and the other end is communicated with the inner cylinder 31; a blower housing 52 is arranged in the circulation duct 5. Under the action of the blower housing 52, the humid and hot air in the inner cylinder 31 enters the outer cylinder 32 through the holes on the inner cylinder 31, then enters the circulation duct 5 through the ventilation port on the outer cylinder 32, and circulates back to the inner cylinder 31.

[0063] Among them, the humid and hot air in the inner cylinder 31 passes through the holes on the inner cylinder 31 and enters the outer cylinder 32, then enters the exhaust duct 2 from the exhaust inlet on the outer cylinder 32, and enters the air - outlet module 12 through the exhaust duct 2. It can effectively prevent the laundry foam in the inner cylinder 31 from entering the exhaust duct 2.

[0064] The inner cylinder 31 is connected to the outer cylinder 32. An air exhaust inlet is provided on the outer cylinder 32 to enable the inner cylinder 31 to be connected to the air exhaust duct, so as to discharge the humid and hot air in the inner cylinder 31 to the outside of the device after being processed by the heat exchange assembly 10. One end of the air exhaust duct 2 is connected to the air exhaust inlet provided on the outer cylinder 32, and the other end is connected to the air path structure 122 in the heat exchange assembly 10. Among them, the flowing cooling medium in the water path structure 121 exchanges heat with the heat conduction plate 123. The humid and hot air in the outer cylinder 32 enters the air path structure 122 and is discharged into the room after being cooled and dehumidified by the heat conduction plate 123.

[0065] In the existing laundry devices, generally there is no fresh air duct 1 for introducing external fresh air into the inner cylinder 31, nor is there an air exhaust duct 2 for discharging the humid and hot air in the inner cylinder 31 and the outer cylinder 32 to the outside of the device.

[0066] Even if the fresh air duct 1 and the air exhaust duct 2 of the fresh air system are added and the humid and hot air is directly discharged to the outside, it will cause the humidity and temperature of the indoor air to be too high. And the indoor air with too high temperature and humidity then enters the inner cylinder 31 through the fresh air duct 1, resulting in the air quality not being guaranteed for a long time and easily causing damage and pollution to the clothes during drying. In this application, the other end of the air exhaust duct 2 is connected to the air path structure 122 of the air outlet module 12, and the humid and hot air is discharged to the outside of the device after being processed by the heat exchange assembly 10, ensuring the temperature and humidity of the outside air, ensuring the air quality entering the inner cylinder through the fresh air duct, reducing peculiar smells, improving the control quality, and achieving efficient drying.

[0067] The heat exchange assembly 10 includes an air outlet module 12 and a box body for accommodating the air outlet module. The box body includes an upper shell 11 and a lower shell 13. In this embodiment, the heat exchange assembly 10 is a heat exchange assembly for water-gas separation, that is, the air outlet module is a water-gas separation air outlet module.

[0068] The air outlet module 12 includes a water path structure 121, a heat conduction plate 123 and an air path structure 122. Preferably, the water path structure 121, the heat conduction plate 123 and the air path structure 122 are all made of heat-conducting materials.

[0069] The heat conduction plate 123 is located between the water path structure 121 and the air path structure 122 of the air outlet module. Preferably, the water path structure 121, the heat conduction plate 123 and the air path structure 122 are integrally formed, or the water path structure 121 and the air path structure 122 are welded to the heat conduction plate 123. And the heat conduction plate 123 separates the water path structure 121 from the air path structure 122, so that the water path structure 121 and the air path structure 122 are not connected, ensuring that the cooling water in the water path structure does not mix with the gas to be cooled in the air path structure, ensuring that the cooling water can flow out at a sufficient speed, increasing the contact area of the cooling water in the water path structure, and ensuring that the temperature of the cooling water can be reused.

[0070] The heat conduction plate 123 is provided with a drain port 1231. Preferably, the drain port 1231 is located at the edge of the heat conduction plate 123. The air duct structure 122 further includes a partition plate 1222. The partition plate 1222 extends from the heat conduction plate in a direction away from the air duct structure and is located at the edge of the drain port, semi-surrounding the drain port 1231, so that the drain port 1231 is directly communicated with the cooling medium outlet 133 on the box body. After the cooling water introduced into the air outlet module 12 circulates in the water channel, it enters the cooling medium outlet 133 through the drain port 1231 without contacting the gas in the air duct structure 122, ensuring that the temperature of the cooling water in the water channel structure 121 can be reused.

[0071] Preferably, the edge of the heat conduction plate 123 is bent towards the water channel structure 121 to form a baffle 124, that is, the baffle 124 and the heat conduction plate 123 form an open groove, and the water channel structure 121 is located in the groove.

[0072] The baffle 124 includes a first baffle 1241, a second baffle 1242, a third baffle 1243 and a fourth baffle 1244. Among them, the first baffle 1241, the second baffle 1242, the third baffle 1243 and the fourth baffle 1244 are connected end to end, and the first baffle 1241 is parallel to the third baffle 1243.

[0073] The heat conduction plate 123 is provided with mounting holes 1233. After the air outlet module 12 is placed in the lower housing 13, it is installed in the mounting holes 1233 by screws or bolts to realize the fixed installation of the heat conduction plate 123 and the lower housing 13.

[0074] The first baffle 1241 is provided with a semi-circular notch 12411. After the upper housing 11 is installed on the lower housing 13, the notch 12411 is located at the cooling medium inlet 111.

[0075] The water channel structure 121 includes: a plurality of upper fins 1211. The upper fins 1211 are rectangular sheet structures without bending, and water channels are formed between adjacent upper fins 1211. A plurality of upper fins 1211 are parallel to each other, and the distance between adjacent upper fins 1211 is equal.

[0076] Preferably, the upper fins 1211 are located in the open groove formed by the baffle 124 and the heat conduction plate 123, that is, the water channel structure 121 is located in the groove.

[0077] All the upper fins 1211 are parallel to each other. Adjacent two upper fins 1211 are respectively fixedly connected to or integrally formed with the first baffle 1241 and the third baffle 1243 to form a continuously bent water channel.

[0078] See Figure 6 and Figure 7, the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle or an acute angle. The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211. It can be understood that the upper fin 1211 is perpendicular to the first baffle 1241 and the third baffle 1243, or inclined to the first baffle 1241 and the third baffle 1243. That is, the upper fin 1211 is perpendicular to the connecting end of the upper fin 1211, or inclined to the connecting end of the upper fin 1211.

[0079] Reference Figure 6 , the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle, that is, the upper fin 1211 is perpendicular to the first baffle 1241 or the third baffle 1243. The cooling medium inlet 111 is located between the vertical upper fin 1211 and the second baffle 1242. The cooling medium enters the water channel directly without obstruction from the cooling medium inlet 111, accelerating the flow rate of the cooling medium, increasing the flow rate of the cooling medium in the water channel structure per unit time, and improving the heat exchange efficiency.

[0080] Preferably, reference Figure 7 , the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is an acute angle, that is, the upper fin 1211 is inclined to the first baffle 1241 or the third baffle 1243. When the upper housing 11 and the lower housing 13 are installed, the cooling medium inlet 111 is located between the inclined upper fin 1211 and the second baffle 1242. When the cooling medium enters the water channel from the cooling medium inlet 111, it impacts the upper fin 1211, and then the cooling medium flows into the remaining water channels. The water flow impacting the upper fin 1211 is more conducive to the heat transfer of the cooling water and improves the heat exchange efficiency.

[0081] The upper fins 1211 are designed to be parallel to each other and cross-connected to the opposing first baffle 1241 and third baffle 1243, which can increase the area of the water channel and the contact area between the cooling medium and the heat conducting plate 123. See Figure 6 , all parts of the heat conducting plate 123 are in contact with the cooling medium, and the sheet structure of the upper fin 1211 without bending design reduces the manufacturing cost.

[0082] The air duct structure 122 includes: a plurality of lower fins 1221 and partitions 1222. At least two of the lower fins 1221 are arc-shaped lower fins, and an arc-shaped air duct is formed between adjacent arc-shaped lower fins.

[0083] Preferably, each lower fin 1221 is arc-shaped, and an air duct is formed between adjacent lower fins 1221. Preferably, the air duct is also arc-shaped.

[0084] The lower fins are fixed to the heat conducting plate 123 in the air outlet module 12, and a drain port 1231 is provided on the heat conducting plate 123. The partition 1222 surrounds the drain port 1231.

[0085] Preferably, in this embodiment, since the heat conducting plate 123 is generally square, the sizes of each of the plurality of lower fins 1221 are different. Specifically, the distances between the plurality of lower fins 1221 are equal, that is, the widths of the water channels formed by the lower fins 1221 are the same. The arcs of the plurality of lower fins 1221 are all the same, so that the plurality of lower fins 1221 are parallel to each other, and the arc is from 10 degrees to 90 degrees.

[0086] Specifically, referring to Figure 2 , the lower fin 1221 includes a root portion 12211 and an end portion 12212. The root portion 12211 is fixed to the heat conducting plate 123 in the air outlet module 12, and the end portion 12212 abuts against the lower housing 13 of the air outlet module 12. Preferably, the thickness of the root portion 12211 is greater than the thickness of the end portion 12212. While ensuring the structural strength, the material consumption is saved.

[0087] Preferably, the inner arc of the lower fin 1221 faces the air inlet 132 of the air outlet module 12, so that the air entering the air duct from the air inlet 132 impacts the lower fin 1221 and then enters each air duct, increasing the contact area of the air and improving the cooling speed of the humid and hot air.

[0088] Preferably, in this embodiment, referring to Figure 4 , the number of the lower fins 1221 is 7. The inner arc of the first lower fin faces the air inlet 132 of the air outlet module 12, and the air duct formed between the sixth lower fin and the seventh lower fin faces the air outlet 131.

[0089] The box body includes an upper housing 11 and a lower housing 13. A cooling medium inlet 111 is provided on the upper housing 11, and an air inlet 132, an air outlet 131 and a cooling medium outlet 133 are provided on the lower housing 13. A semi-circular piece of baffle is provided at the air outlet 131, so that the shape of the air outlet 131 is semi-circular, and the baffle is located at the bottom of the air outlet 131 to prevent water from being discharged.

[0090] The heat conducting plate 123 is made of heat conducting materials, such as metals and alloys. The upper housing 11 and the lower housing 13 are made of plastics or metals.

[0091] The air inlet 132 is higher than the air outlet 131, and the air inlet 132 is larger than the air outlet 131 to avoid causing air flow disorder. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to timely discharge the condensed water, so as to avoid excessive condensed water content in the air outlet module 12, which may lead to an increase in the humidity of the air outlet module 12 and is not conducive to dehumidifying the humid and hot air.

[0092] The lower housing 13 includes a side wall and a bottom, and the bottom is an inclined bottom. The cooling medium outlet 133 is located at the inclined bottom.

[0093] Preferably, the inclined bottom includes a first inclined surface 134, a second inclined surface 135, and a third inclined surface 136. The first inclined surface 134 and the third inclined surface 136 are located on both sides of the second inclined surface 135. The upper ends of the first inclined surface 134 and the third inclined surface 136 are connected to the side wall, and the lower ends are connected to the second inclined surface 135. It can be understood that the first inclined surface 134 and the third inclined surface 136 are transition surfaces between the second inclined surface 135 and the side wall. A transition inclined surface 137 is also provided between the side wall and the second inclined surface 135.

[0094] The cooling medium outlet 133 is located on the second inclined surface 135. Due to the guiding effect of the self - gravity of the condensed water, the condensed water will eventually fall onto the bottom of the lower housing 13. Due to the design of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136 and the transition inclined surface 137, the cooling medium outlet 133 is much lower than the cooling medium inlet 111, so as to discharge the cooling medium in time, so as to avoid excessive condensed water content in the air outlet module 12, and at the same time avoid the accumulation of condensed water at the bottom, which may lead to an increase in the humidity of the air outlet module 12 and is not conducive to the dehumidification of the humid and hot air.

[0095] Moreover, due to the structural and positional design of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136 and the transition inclined surface 137, the structure of the lower housing 13 is more smooth, reducing the noise of the cooling medium in the heat exchange component 10.

[0096] The air inlet 132 and the air outlet 131 are located on two adjacent side walls. The arc surface of the lower fin 1221 faces the air inlet 132, so that the air entering the air duct from the air inlet 132 impacts the lower fin 1221 and then enters each air duct, increasing the contact area of the air and improving the cooling speed of the humid and hot air. Due to the arc design of the lower fin 1221, the air outlet 131 is located on the side wall adjacent to the air inlet 132.

[0097] Both the upper housing 11 and the lower housing 13 are groove structures. After the upper housing 11 and the lower housing 13 are fixedly installed, an accommodation space for accommodating the air outlet module 12 is formed. The upper housing 11 and the lower housing 13 can be snap - fitted. Preferably, the upper housing 11 can be screwed to the air outlet module 12 to achieve fixation after snap - fitting.

[0098] After the upper housing 11 and the lower housing 13 are snapped together, the cooling medium inlet 111 is located between the baffle 124 and the upper fin 1211. The air inlet 132 is higher than the air outlet 131. And the cooling water enters the water channel structure 121 through the cooling medium inlet 111, flows into each water channel after being impacted by the upper fin 1211, and cools the humid and hot air in the air channel structure 122 through the heat conduction of the heat conduction plate 123. The cooling water flows into the lower housing 13 through the drain port 1231 and is discharged from the cooling medium outlet 133 at the bottom of the lower housing 13. At the same time, the humid and hot air discharged from the clothing device enters the air channel structure 122 through the air inlet 132, flows into each air duct after being impacted by the lower fin 1221, and is discharged from the air outlet 131 after being cooled by the heat conduction plate 123 into low-temperature and low-humidity air.

[0099] In short, the cooling medium enters the water channel structure 121 from the cooling medium inlet. The cooling medium will carry away the heat of the heat conduction plate 123 and flow out from the cooling medium outlet 133 at the bottom of the lower housing 13. The heat conduction plate 123 realizes the heat exchange between the cooling water in the water channel structure 121 and the humid and hot air in the air channel structure 122. The humid and hot air in the inner cylinder 31 enters the exhaust air duct 2 from the exhaust air inlet on the outer cylinder 32, then enters the air channel structure 122 from the air inlet 132, and is cooled and dehumidified by the heat conduction plate 123 and then discharged into the room as low-temperature and low-heat air from the air outlet 131.

[0100] In the present invention, the cooling water in the water channel structure 121 flows on the heat conduction plate 123 to cool the high-temperature and high-humidity gas in the air channel structure 122, turn the high-temperature and high-humidity gas after drying the clothes into low-temperature and low-humidity air and discharge it outside the clothing device, remove the peculiar smell of the clothes, and ensure the temperature and humidity of the outside air, ensure the air quality entering the inner cylinder through the fresh air duct, reduce the peculiar smell and improve the control quality, so as to achieve efficient drying.

[0101] The heat conduction plate 123 in the present invention is provided with through holes 1232. The through holes 1232 connect the water channel structure 121 and the air channel structure 122 to mix water and gas. Part of the cooling water in the water channel structure 121 is mixed with the high-temperature and high-humidity gas discharged from the device through the through holes 1232, improving the cooling efficiency of the high-temperature and high-humidity gas.

[0102] In the present invention, the design of the water channel structure 121 increases the contact area between the cooling medium and the heat conduction plate 123, improving the cooling efficiency. And the design of the air channel structure 122 increases the channel length of the gas, improving the cooling efficiency of the humid and hot air.

[0103] In the present invention, the cooling medium outlet 133 is located at the bottom of the inclined lower housing 13. The bottom of the lower housing 13 includes a plurality of inclined surfaces to timely discharge the cooling medium, avoid the accumulation of condensed water at the bottom, and improve the dehumidification efficiency.

[0104] Embodiment 2:

[0105] See Figures 1 - 3 、 Figures 9 - 15 A direct-discharge fresh air laundry device, comprising: a box body, an inner cylinder 31, an outer cylinder 32, a fresh air duct 1, an exhaust duct 2, and a heat exchange assembly 10.

[0106] The box body constitutes the basic external structure of the direct-discharge fresh air laundry device.

[0107] The inner cylinder 31 and the outer cylinder 32 are arranged inside the box body. The inner cylinder 31 is used to accommodate the clothes to be dried. The inner cylinder 31 is arranged inside the outer cylinder 32 and is communicated with the outer cylinder 32 through the holes (not shown in the figure) on the inner cylinder 31. The humid and hot air inside the inner cylinder 31 can enter the outer cylinder 32. An exhaust inlet is provided on the outer cylinder 32.

[0108] The fresh air duct 1, one end of the fresh air duct 1 is a fresh air inlet arranged on the front panel or the upper top panel of the box body, that is, one end of the fresh air duct 1 is communicated with the external fresh air, and the air outside the box enters the fresh air duct through the fresh air inlet. The other end of the fresh air duct 1 is communicated with the inner cylinder 31 of the laundry device to introduce the external fresh air into the inner cylinder 31 of the laundry device.

[0109] The exhaust duct 2, one end of the exhaust duct 2 is an exhaust inlet arranged on the outer cylinder, and the other end is communicated with the air duct structure 122 of the air outlet module 12; the humid and hot air inside the inner cylinder of the laundry device first enters the outer cylinder 32 through the holes on the inner cylinder 31, and the humid and hot air inside the outer cylinder 32 enters the exhaust duct 2 from the exhaust inlet and enters the air outlet module 12 through the exhaust duct 2.

[0110] The circulation duct 5, one end of the circulation duct 5 is a ventilation port arranged on the outer cylinder 32, and the other end is communicated with the inner cylinder 31; a fan volute 52 is arranged inside the circulation duct 5. Under the action of the fan volute 52, the humid and hot air inside the inner cylinder 31 enters the outer cylinder 32 through the holes on the inner cylinder 31, and then enters the circulation duct 5 through the ventilation port on the outer cylinder 32 and circulates back to the inner cylinder 31.

[0111] Wherein, the humid and hot air inside the inner cylinder 31 passes through the holes on the inner cylinder 31 and enters the outer cylinder 32, then enters the exhaust duct 2 through the exhaust inlet on the outer cylinder 32, and enters the air outlet module 12 through the exhaust duct 2. It can effectively prevent the laundry foam inside the inner cylinder 31 from entering the exhaust duct 2.

[0112] The inner cylinder 31 is connected to the outer cylinder 32, and an exhaust air inlet is provided on the outer cylinder 32 to enable the inner cylinder 31 to be connected to the exhaust air duct, so as to discharge the humid and hot air in the inner cylinder 31 out of the device after being processed by the heat exchange component 10. One end of the exhaust air duct 2 is connected to the exhaust air inlet provided on the outer cylinder 32, and the other end is connected to the air path structure 122 in the heat exchange component 10. Among them, the flowing cooling medium in the water path structure 121 exchanges heat with the heat conduction plate 123, and the humid and hot air in the outer cylinder 32 enters the air path structure 122 and is discharged into the room after being cooled and dehumidified by the heat conduction plate 123.

[0113] In the existing laundry device, generally there is no fresh air duct 1 for external fresh air to enter the inner cylinder 31, nor is there an exhaust air duct 2 for discharging the humid and hot air in the inner cylinder 31 and the outer cylinder 32 out of the device.

[0114] Even if the fresh air duct 1 and the exhaust air duct 2 of the fresh air system are added and the humid and hot air is directly discharged to the outside, it will cause the humidity and temperature of the indoor air to be too high. And the air with too high temperature and humidity indoors then enters the inner cylinder 31 through the fresh air duct 1, resulting in the inability to ensure the air quality for a long time and easily causing damage and pollution to the clothes during drying. In this application, the other end of the exhaust air duct 2 is connected to the air path structure 122 of the air outlet module 12, and the humid and hot air is discharged out of the device after being processed by the heat exchange component 10, ensuring the temperature and humidity of the outside air, ensuring the air quality entering the inner cylinder through the fresh air duct, reducing peculiar smells, improving the control quality, and achieving efficient drying.

[0115] The heat exchange component 10 includes an air outlet module 12 and a box body for accommodating the air outlet module. The box body includes an upper shell 11 and a lower shell 13. In this embodiment, the heat exchange component 10 is a heat exchange component of water and gas mixture, that is, the air outlet module is a mixing module of water and gas separation.

[0116] The air outlet module 12 includes a water path structure 121, a heat conduction plate 123 and an air path structure 122. Preferably, the water path structure 121, the heat conduction plate 123 and the air path structure 122 are all made of heat-conducting materials.

[0117] The heat conduction plate 123 is located between the water path structure 121 and the air path structure 122 of the air outlet module. Preferably, the water path structure 121, the heat conduction plate 123 and the air path structure 122 are integrally formed, or the water path structure 121 and the air path structure 122 are welded to the heat conduction plate 123. And the heat conduction plate 123 is provided with a plurality of through holes 1232, and the through holes 1232 connect the water path structure 121 and the air path structure 122, so that the cooling water in the water path structure 121 is mixed with the gas to be cooled in the air path structure, and the cooling rate of the gas to be cooled is accelerated.

[0118] The heat conducting plate 123 is provided with a drain port 1231. Preferably, the drain port 1231 is located at the edge of the heat conducting plate 123. The air duct structure 122 further includes a partition plate 1222. The partition plate 1222 extends from the heat conducting plate in a direction away from the air duct structure and is located at the edge of the drain port, semi - surrounding the drain port 1231 so that the drain port 1231 is directly communicated with the cooling medium outlet 133 on the box body. Preferably, the size of the drain port 1231 is larger than the size of the through - hole 1232. After the water duct structure 121 is filled with the cooling medium, a large amount of the cooling medium is discharged from the drain port 1231, and a small amount of the cooling medium flows into the air duct structure 122 from the water duct structure 121 to cool the high - temperature and high - humidity gas and then is discharged.

[0119] Preferably, the edge of the heat conducting plate 123 is bent towards the water duct structure 121 to form a baffle 124, that is, the baffle 124 and the heat conducting plate 123 form an open groove, and the water duct structure 121 is located in the groove.

[0120] The baffle 124 includes a first baffle 1241, a second baffle 1242, a third baffle 1243 and a fourth baffle 1244. Among them, the first baffle 1241, the second baffle 1242, the third baffle 1243 and the fourth baffle 1244 are connected end to end, and the first baffle 1241 is parallel to the third baffle 1243.

[0121] The heat conducting plate 123 is provided with mounting holes 1233. After the air outlet module 12 is placed in the lower housing 13, it is installed in the mounting holes 1233 by screws or bolts to realize the fixed installation of the heat conducting plate 123 and the lower housing 13.

[0122] The first baffle 1241 is provided with a semi - circular notch 12411. After the upper housing 11 is installed on the lower housing 13, the notch 12411 is located at the cooling medium inlet 111.

[0123] The water duct structure 121 includes: a plurality of upper fins 1211. The upper fins 1211 are rectangular sheet - like structures without bending, and water channels are formed between adjacent upper fins 1211. A plurality of upper fins 1211 are parallel to each other, and the distance between adjacent upper fins 1211 is equal.

[0124] Preferably, the upper fins 1211 are located in the open groove formed by the baffle 124 and the heat conducting plate 123, that is, the water duct structure 121 is located in the groove.

[0125] All the upper fins 1211 are parallel to each other, and two adjacent upper fins 1211 are respectively fixedly connected to or integrally formed with the first baffle 1241 and the third baffle 1243 to form a continuously bent water channel.

[0126] See Figure 11 and Figure 12, the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle or an acute angle. It can be understood that the upper fin 1211 is perpendicular to the first baffle 1241 and the third baffle 1243, or inclined to the first baffle 1241 and the third baffle 1243.

[0127] The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211. That is, the upper fin 1211 is perpendicular to the connecting end of the upper fin 1211, or inclined to the connecting end of the upper fin 1211.

[0128] Reference Figure 11 , the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle, that is, the upper fin 1211 is perpendicular to the first baffle 1241 or the third baffle 1243. The cooling medium inlet 111 is located between the vertical upper fin 1211 and the second baffle 1242. The cooling medium directly enters the water channel from the cooling medium inlet 111 without obstruction, accelerating the flow rate of the cooling medium, increasing the flow rate of the cooling medium in the water channel structure per unit time, and improving the heat exchange efficiency.

[0129] Preferably, reference Figure 12 , the included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is an acute angle, that is, the upper fin 1211 is inclined to the first baffle 1241 or the third baffle 1243. When the upper housing 11 and the lower housing 13 are installed, the cooling medium inlet 111 is located between the inclined upper fin 1211 and the second baffle 1242. When the cooling medium enters the water channel from the cooling medium inlet 111, it impacts the upper fin 1211, and then the cooling medium flows into the remaining water channels. The water flow impacting the upper fin 1211 is more conducive to the heat transfer of the cooling water and improves the heat exchange efficiency.

[0130] The upper fins 1211 are designed to be parallel to each other and cross-connected to the opposing first baffle 1241 and third baffle 1243, which can increase the area of the water channel and the contact area between the cooling medium and the heat conducting plate 123. See Figure 6 , all parts of the heat conducting plate 123 are in contact with the cooling medium, and the sheet structure of the upper fin 1211 without bending design reduces the manufacturing cost.

[0131] The air duct structure 122 includes: a plurality of lower fins 1221 and partitions 1222. At least two of the lower fins 1221 are arc-shaped lower fins, and an arc-shaped air duct is formed between adjacent arc-shaped lower fins.

[0132] Preferably, each lower fin 1221 is arc-shaped, and an air duct is formed between adjacent two lower fins 1221. Preferably, the air duct is also arc-shaped.

[0133] The lower fins are fixed to the heat conducting plate 123 in the air outlet module 12, and a drain port 1231 is provided on the heat conducting plate 123. The partition plate 1222 surrounds the drain port 1231.

[0134] Preferably, in this embodiment, since the heat conducting plate 123 is generally square, the sizes of each of the several lower fins 1221 are different. Specifically, the distances between the several lower fins 1221 are equal, that is, the widths of the water channels formed by the lower fins 1221 are the same. The arcs of the several lower fins 1221 are the same, so that the several lower fins 1221 are parallel to each other, and the arc is from 10 degrees to 90 degrees.

[0135] Specifically, referring to Figure 2 , the lower fin 1221 includes a root portion 12211 and an end portion 12212. The root portion 12211 is fixed to the heat conducting plate 123 in the air outlet module 12, and the end portion 12212 abuts against the lower housing 13 of the air outlet module 12. Preferably, the thickness of the root portion 12211 is greater than the thickness of the end portion 12212. While ensuring the structural strength, the material consumption is saved.

[0136] Preferably, the inner arc of the lower fin 1221 faces the air inlet 132 of the air outlet module 12, so that the air entering the air duct from the air inlet 132 impacts the lower fin 1221 and then enters each air duct, increasing the contact area of the air and improving the cooling speed of the humid and hot air.

[0137] Preferably, in this embodiment, referring to Figure 9 , the number of the lower fins 1221 is 7. The inner arc of the first lower fin faces the air inlet 132 of the air outlet module 12, and the air duct formed between the sixth lower fin and the seventh lower fin faces the air outlet 131.

[0138] The box body includes an upper housing 11 and a lower housing 13. A cooling medium inlet 111 is provided on the upper housing 11, and an air inlet 132, an air outlet 131 and a cooling medium outlet 133 are provided on the lower housing 13. A semi-circular piece of baffle is provided at the air outlet 131, so that the shape of the air outlet 131 is semi-circular. The baffle is located at the bottom of the air outlet 131 to prevent water from being discharged.

[0139] The heat conducting plate 123 is made of heat conducting materials, such as metals and alloys. The upper housing 11 and the lower housing 13 are made of plastics or metals.

[0140] The air inlet 132 is higher than the air outlet 131, and the air inlet 132 is larger than the air outlet 131 to avoid causing air flow disorder. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to timely discharge the condensed water, so as to avoid excessive condensed water content in the air outlet module 12, which may lead to an increase in the humidity of the air outlet module 12 and is not conducive to dehumidifying the humid and hot air.

[0141] Referring toFigures 14 - 15 , the lower housing 13 includes a side wall and a bottom, the bottom is an inclined bottom, and the cooling medium outlet 133 is located on the inclined bottom.

[0142] Preferably, the inclined bottom includes a first inclined surface 134, a second inclined surface 135, and a third inclined surface 136. The first inclined surface 134 and the third inclined surface 136 are located on both sides of the second inclined surface 135. The upper ends of the first inclined surface 134 and the third inclined surface 136 are connected to the side wall, and the lower ends are connected to the second inclined surface 135. It can be understood that the first inclined surface 134 and the third inclined surface 136 are transition surfaces between the second inclined surface 135 and the side wall. A transition inclined surface 137 is also provided between the side wall and the second inclined surface 135.

[0143] The cooling medium outlet 133 is located on the second inclined surface 135. Due to the guiding effect of the self-gravity of the condensed water, the condensed water will eventually fall onto the bottom of the lower housing 13. Due to the design of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136, and the transition inclined surface 137, the cooling medium outlet 133 is much lower than the cooling medium inlet 111, so as to discharge the cooling medium in time to prevent the condensed water content in the air outlet module 12 from being too much, and at the same time avoid the accumulation of condensed water at the bottom, resulting in an increase in the humidity of the air outlet module 12, which is not conducive to the dehumidification of the humid and hot air.

[0144] And due to the structural and positional design of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136, and the transition inclined surface 137, the structure of the lower housing 13 is more smooth, reducing the noise of the cooling medium in the heat exchange component 10.

[0145] The air inlet 132 and the air outlet 131 are located on two adjacent side walls. The arc surface of the lower fin 1221 faces the air inlet 132, so that the air entering the air duct from the air inlet 132 impacts the lower fin 1221 and then enters each air duct, increasing the contact area of the air and improving the cooling speed of the humid and hot air. Due to the arc design of the lower fin 1221, the air outlet 131 is located on the side wall adjacent to the air inlet 132.

[0146] Both the upper housing 11 and the lower housing 13 are groove structures. After the upper housing 11 and the lower housing 13 are fixedly installed, an accommodation space for accommodating the air outlet module 12 is formed. The upper housing 11 and the lower housing 13 can be snap-fitted. Preferably, the upper housing 11 can be screwed to the air outlet module 12 to achieve fixation after snap-fitting.

[0147] After the upper housing 11 and the lower housing 13 are snapped together, the cooling medium inlet 111 is located between the baffle 124 and the upper fin 1211. The air inlet 132 is higher than the air outlet 131. And the cooling water enters the water channel structure 121 through the cooling medium inlet 111, flows into each water channel after being impacted by the upper fin 1211, and cools the humid and hot air in the air channel structure 122 through the heat conduction of the heat conduction plate 123. The cooling water flows into the lower housing 13 through the drain port 1231 and is discharged from the cooling medium outlet 133 at the bottom of the lower housing 13. At the same time, the humid and hot air discharged from the clothing device enters the air channel structure 122 through the air inlet 132, flows into each air duct after being impacted by the lower fin 1221, and is discharged from the air outlet 131 after being cooled by the heat conduction plate 123 into low-temperature and low-humidity air.

[0148] In short, the cooling medium enters the water channel structure 121 from the cooling medium inlet. The cooling medium will take away the heat of the heat conduction plate 123 and flow out from the cooling medium outlet 133 at the bottom of the lower housing 13. The heat conduction plate 123 realizes the heat exchange between the cooling water in the water channel structure 121 and the humid and hot air in the air channel structure 122. The humid and hot air in the inner cylinder 31 enters the exhaust air duct 2 from the exhaust air inlet on the outer cylinder 32, then enters the air channel structure 122 from the air inlet 132, and is discharged from the air outlet 131 into the room after being cooled and dehumidified by the heat conduction plate 123 into low-temperature and low-heat air.

[0149] In the present invention, the cooling water in the water channel structure 121 flows on the heat conduction plate 123 to realize the cooling of the high-temperature and high-humidity gas in the air channel structure 122, turns the high-temperature and high-humidity gas after drying the clothes into low-temperature and low-humidity air and discharges it outside the clothing device, removes the peculiar smell of the clothes, and ensures the temperature and humidity of the outside air, ensures the air quality entering the inner cylinder through the fresh air duct, reduces the peculiar smell, improves the control quality, and achieves efficient drying.

[0150] The heat conduction plate 123 in the present invention is provided with through holes 1232. The through holes 1232 connect the water channel structure 121 and the air channel structure 122 to mix the water vapor. Part of the cooling water in the water channel structure 121 is mixed with the high-temperature and high-humidity gas discharged from the device through the through holes 1232, improving the cooling efficiency of the high-temperature and high-humidity gas.

[0151] In the present invention, the design of the water channel structure 121 increases the contact area between the cooling medium and the heat conduction plate 123, improving the cooling efficiency. And the design of the air channel structure 122 increases the channel length of the gas, improving the cooling efficiency of the humid and hot air.

[0152] In the present invention, the cooling medium outlet 133 is located at the bottom of the inclined lower housing 13. The bottom of the lower housing 13 includes a plurality of inclined surfaces to timely discharge the cooling medium, avoid the accumulation of condensed water at the bottom, and improve the dehumidification efficiency.

[0153] In some embodiments, the clothing device is a dryer or a washer-dryer. When it is a washer-dryer, it correspondingly has a laundry structure and laundry function, and preferably it is a drum-type washer-dryer.

[0154] A direct-exhaust fresh-air laundry device provided by the present invention is installed at the end of the exhaust air duct 2 of the device, processes the high-temperature and high-humidity air in the inner cylinder and then discharges it, and can also prevent the problem of foam overflow caused by excessive use of washing powder.

[0155] The cooling water in the water path structure 121 cools the high-temperature and high-humidity gas in the air path structure 122, turns the high-temperature and high-humidity gas after washing or drying the clothes into low-temperature and low-humidity air and discharges it outside the device, removes the peculiar smell of the clothes, and ensures the temperature and humidity of the outside air, ensures the air quality entering the inner cylinder through the fresh-air duct, reduces peculiar smells and improves the control quality, so as to achieve efficient laundry or drying.
