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

[0072] Embodiment 1:

[0073] See Figures 1-8 、 Figures 14-18 The present invention also provides a direct-discharge type clothing care device based on a fresh air system, including: a box body, an inner cylinder 31, an outer cylinder 32, an air inlet module 20 for disinfecting external fresh air, a heat exchange component 10 for cooling and dehumidifying humid and hot gas, a fresh air duct 1 for introducing external fresh air into the device, a connection duct 6 for discharging the humid and hot gas in the device, and an exhaust duct 2.

[0074] The box body constitutes the basic external structure of the device.

[0075] The inner cylinder 31 and the outer cylinder 32 are arranged in the box body. The inner cylinder 3 is used to accommodate clothes. 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. The outer cylinder 32 is provided with an exhaust inlet.

[0076] Fresh air duct 1, one end of the fresh air duct 1 is a fresh air inlet provided on the front panel or upper top panel of the cabinet, that is, one end of the fresh air duct 1 communicates with the external fresh air, and the air outside the cabinet enters the fresh air duct through the fresh air inlet. The other end of the fresh air duct 1 communicates with the first air inlet of the air inlet module 20, and the external fresh air is introduced into the inner cylinder 31 after being sterilized by the air inlet module 20.

[0077] Connecting duct 6, one end of the connecting duct 6 communicates with the first air outlet of the air inlet module 20, and the other end communicates with the inner cylinder 31. The fresh air sterilized by the air inlet module 20 enters the inner cylinder 31 through the connecting duct 6.

[0078] Exhaust air duct 2, one end of the exhaust air duct 2 is an exhaust air inlet provided on the outer cylinder, and the other end communicates with the air path structure 122 of the air outlet module 12; the humid and hot air in the inner cylinder first enters the outer cylinder 32 through the holes on the inner cylinder 31, and then enters the exhaust air duct 2 from the exhaust air inlet, and enters the heat exchange component 10 through the exhaust air duct 2.

[0079] Circulation duct 5, one end of the circulation duct 5 is a ventilation port provided on the outer cylinder 32, and the other end communicates with the inner cylinder 31; preferably, a heating component 51 and a fan housing 52 are provided on the circulation duct 5. Under the action of the fan 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, and then enters the circulation duct 5 through the ventilation port on the outer cylinder 32, and is circulated back to the inner cylinder 31 after being heated by the heating component 51.

[0080] Among them, the humid and hot air in the inner cylinder 31 passes through the holes on the inner cylinder 31 into the outer cylinder 32, then enters the exhaust air duct 2 through the exhaust air inlet on the outer cylinder 32, and enters the air outlet module 12 through the exhaust air duct 2. It can effectively prevent the laundry foam in the inner cylinder 31 from entering the exhaust air duct 2.

[0081] The inner cylinder 31 communicates with the outer cylinder 32, and the outer cylinder 32 is provided with an exhaust air inlet to realize the connection between the inner cylinder 31 and 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 communicates with the exhaust air inlet provided on the outer cylinder 32, and the other end communicates with 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 conducting plate 123, and the humid and hot air in the device enters the air path structure 122 of the heat exchange component 10 through the exhaust air duct 2, and is discharged to the room after being cooled and dehumidified by the heat exchange component 10.

[0082] In order to realize the controlled connection with the inner cylinder, the air inlet module 20 is provided with a damper. When the damper is opened, the indoor fresh air enters the inner cylinder 31 after being sterilized by the air inlet module 20.

[0083] 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 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.

[0084] 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 indoor air with too high temperature and humidity 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 it is easy to cause damage and pollution to the clothes drying. In this application, the other end of the exhaust air duct 2 is connected to the air path structure 121 of the air outlet module 12, and the humid and hot air is discharged outside 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 smell and improving the control quality, so as to achieve efficient drying. And an air inlet module 20 is arranged at the fresh air duct 1, which can realize the control connection with the inner cylinder, laying a foundation for subsequent automatic control. And when the air door is opened, the indoor fresh air enters the inner cylinder 31 after being sterilized by the air inlet module 20, ensuring the air quality of the inner cylinder in the device and reducing peculiar smell.

[0085] Specifically, the heat exchange component 10 includes an air outlet module 12 and an air outlet box body for accommodating the air outlet module. The air outlet 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 for water-gas separation, that is, the air outlet module is a water-gas separation air outlet module.

[0086] 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.

[0087] 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 is not connected to the air path structure 122, that is, the water path structure 121 is isolated from the air path structure 122 to achieve water-gas separation, so that the cooling water in the water path structure 121 is not isolated from the gas to be cooled in the air path structure, ensuring that the cooling water can flow out at a faster 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.

[0088] 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 second partition plate 1222. The second 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 air outlet 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.

[0089] Preferably, the edge of the heat conducting plate 123 is bent towards the water channel 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 channel structure 121 is located in the groove.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] The water channel structure 121 includes: a plurality of upper fins 1211. The upper fins 1211 are rectangular sheet-like structures without bending. 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. The bottom of the upper fins 1211 is integrally formed on the heat conducting plate 123, and all the upper fins 1211 are parallel to each other, so that the water channels formed between the upper fins 1211 cover the entire heat conducting plate 123, increasing the contact area between the cooling medium and the heat conducting plate 123.

[0094] 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 channel structure 121 is located in the groove.

[0095] All the upper fins 1211 are parallel to each other. 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.

[0096] See Figure 6 and Figure 7 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. 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. The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211, and 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.

[0097] Refer to Figure 6 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 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.

[0098] Preferably, refer to Figure 7 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.

[0099] 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 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.

[0100] The air duct structure 122 includes: a plurality of lower fins 1221 and a second partition 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.

[0101] 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.

[0102] The lower fins are fixed to the heat conduction plate 123 in the air outlet module 12, and a drain outlet 1231 is provided on the heat conduction plate 123. The second partition 1222 surrounds the drain outlet 1231.

[0103] Preferably, in this embodiment, since the heat conduction 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 10 degrees to 90 degrees.

[0104] Specifically, referring to Figure 2 , the lower fin 1221 includes a root 12211 and an end 12212. The root 12211 is fixed to the heat conduction plate 123 in the air outlet module 12, and the end 12212 abuts against the lower housing 13 of the air outlet module 12. Preferably, the thickness of the root 12211 is greater than the thickness of the end 12212. While ensuring the structural strength, the material consumption is saved.

[0105] Preferably, the inner arc of the lower fin 1221 faces the second air inlet 132 of the air outlet module 12, so that the air entering the air duct from the second 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.

[0106] 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 second 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 second air outlet 131.

[0107] The air outlet 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 a second air inlet 132, a second air outlet 131 and a cooling medium outlet 133 are provided on the lower housing 13. A semi-circular sheet baffle is provided at the second air outlet 131, so that the shape of the second air outlet 131 is semi-circular, and the baffle is located at the bottom of the second air outlet 131 to prevent water from being discharged.

[0108] The heat conduction plate 123 is made of a heat-conducting material, such as metals and alloys. The upper housing 11 and the lower housing 13 are made of plastic or metal.

[0109] The second air inlet 132 is higher than the second air outlet 131, and the second air inlet 132 is larger than the second 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.

[0110] The lower housing 13 includes a side wall and a bottom, the bottom being an inclined bottom, and the cooling medium outlet 133 is located on the inclined bottom.

[0111] 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.

[0112] 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, 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.

[0113] 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.

[0114] The second air inlet 132 and the second air outlet 131 are located on two adjacent side walls. The arc surface of the lower fin 1221 faces the second air inlet 132, so that the air entering the air duct from the second 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 second air outlet 131 is located on the side wall adjacent to the second air inlet 132.

[0115] 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.

[0116] 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 second air inlet 132 is higher than the second 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 drying device enters the air channel structure 122 through the second air inlet 132, flows into each air duct after being impacted by the lower fin 1221, and is discharged from the second air outlet 131 after being cooled by the heat conduction plate 123 into low-temperature and low-humidity air.

[0117] 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, and then enters the air channel structure 122 from the second air inlet 132. After being cooled and dehumidified by the heat conduction plate 123, it becomes low-temperature and low-heat air and is discharged from the second air outlet 131 into the room.

[0118] Reference Figures 16-18 , the air inlet module 20 includes: an air inlet box body, a damper 23, a driving member 25, and an anion generator.

[0119] The air inlet box body includes a bottom box 21 and an upper cover 22, and the upper cover 22 is snapped onto the bottom box 21. Preferably, the bottom box 21 is provided with a lower snap portion, and the upper cover 22 is provided with an upper snap portion, and the upper snap portion and the lower snap portion are snapped and sealed.

[0120] The bottom box 21 of the air inlet box body is provided with a first air inlet 2121 and a first air outlet 2111; the damper 23 is rotatably installed on the bottom box 21 of the air inlet box body; the first air inlet 2121 and the first air outlet 2111 are located on both sides of the damper 23. When the damper 23 is in the open state, it realizes the communication between the first air inlet 2121 and the first air outlet 2111.

[0121] The first air inlet 2121 is connected to the fresh air outside the device, and the first air outlet 2111 is connected to the inner cylinder of the clothing drying device.

[0122] The bottom box 21 includes a first region 2110 and a second region 2120. The bottom box 21 is provided with a first partition 2130, and a ventilation opening 2131 is provided on the first partition 2130, that is, a ventilation opening 2131 is provided between the first region 2110 and the second region 2120; the air damper 23 is installed in the second region 2120, and the air damper 23 is rotatably installed on the box body. When the air damper 23 is in the closed state, it hermetically covers the ventilation opening 2131. In other embodiments, the air damper is installed on the box body, and the air damper can linearly displace on the box body to open the ventilation opening 2131. Preferably, the first air inlet 2121 is located in the second region 2120, the first air outlet 2111 is located in the first region 2110, and the air damper 23 is located in the second region 2120, that is, close to the first air inlet 2121. A negative ion generator (not shown in the figure) is connected to the first region 2110 through a pipeline, and the negative ions generated by the negative ion generator dust and purify the air in the first region 2110.

[0123] A negative ion generator is a device that generates air negative ions. The device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit, and then through a pulsed circuit, overvoltage and current limiting; high and low voltage isolation and other circuits to raise it to an AC high voltage, and then through a special grade electronic material rectification and filtering to obtain a pure DC negative high voltage. The DC negative high voltage is connected to a release tip made of metal or carbon element, and a high corona is generated by the tip DC high voltage, and a large number of electrons are released at high speed. Since electrons cannot exist in the air for a long time, they will immediately be captured by oxygen molecules in the air, thereby generating air negative ions.

[0124] The air damper 23 includes a damper body 231, a sealing ring 232, and a mounting shaft 233.

[0125] The damper body 231, the sealing ring 232, and the mounting shaft 233 can be integrally formed; alternatively, the damper body 231 and the mounting shaft 233 are integrally formed, and the sealing ring 232 is fixedly installed on the damper body 231. Preferably, the sealing ring 232 is a flexible material that can achieve sealing. The sealing ring 232 is located on the side of the damper body 231 facing the ventilation opening 2131.

[0126] The sealing ring 232 is located on the side of the damper body 231 facing the ventilation opening 2131. Preferably, the air damper is rotatably installed on the box body, and the air damper 23 opens in the direction of the first air inlet 2121. When the air damper 23 is closed, the wind at the first air inlet 2121 presses the damper body 231 and the sealing ring 232 tightly against the first partition 2130.

[0127] Preferably, a rotation hole is provided on the bottom box 21, and the mounting shaft 233 is rotatably mounted in the rotation hole to rotatably mount the air door 23 on the bottom box 21. Preferably, the air door 23 rotates towards the air inlet, that is, the air door opens towards the direction of the first air inlet 2121. When the air door 23 is closed, the fresh air entering from the first air inlet 2121 can exert pressure on the air door body 231, so that the air door body 231 presses the sealing ring 232 to seal the air door, ensuring that when the air door is closed, the air inlet module does not let air through.

[0128] The driving member 25 is fixedly mounted on the air inlet box body. Preferably, the driving member 25 is fixedly mounted on the outer wall of the bottom box 21. The air door 23 is power-coupled with the driving member 25. In this embodiment, the driving member 25 drives the mounting shaft 233 of the air door 23 to rotate in the mounting hole to open and close the air door 23.

[0129] In other embodiments, the air door is mounted on the box body, and the air door can perform a linear displacement on the box body to open the ventilation opening 2131, and the driving member 25 drives the air door 23 to perform a linear motion.

[0130] The air inlet module 20 further includes a sensor for detecting the position of the air door. When it is detected that the air door is in the open position, the negative ion generator starts to work.

[0131] The air inlet module 20 further includes an angle detection device for obtaining the opening and closing angle of the air door body. The angle detection device includes: a magnet mounted on the mounting shaft 233 and a Hall sensor opposite to the magnet.

[0132] The magnet mounted on the mounting shaft 233 rotates with the mounting shaft 233, and the magnetic field of the magnet along the direction of the mounting shaft 233 changes as the magnet rotates;

[0133] The Hall sensor opposite to the magnet can detect the opening and closing angle of the air door body 231 according to the change of the magnetic field.

[0134] The magnet rotates with the air door, and the magnetic field along the main shaft body direction also changes with the rotation. The Hall sensor detects the opening and closing angle of the air door body 231 according to the change of the magnetic field, and can quickly, accurately and efficiently detect the opening and closing angle.

[0135] The Hall sensor is an angle Hall sensor. The angle Hall sensor detects the opening and closing angle of the air door according to the change of the magnetic field. Specifically, the angle Hall sensor converts the spatial position change amount of the N and S magnetic fields of the magnet into the angle change amount of the main shaft body, and outputs the angle change amount to the main control unit in the form of a digital quantity.

[0136] When the opening and closing angle of the air door body is greater than the angle threshold, the negative ion generator works. It can be understood that the air door body needs to open to a certain angle before the negative ion generator can work, laying a foundation for subsequent implementation of automatic control.

[0137] A direct-discharge type clothing care device based on a fresh air system provided by the present invention is provided with an air inlet module 20 at the fresh air duct 1, which can sterilize the fresh air entering the outside of the inner cylinder 31 and control the opening of the air door 23 according to requirements; an air heat exchange component 10 is provided at the exhaust air duct 2, which can turn the high-temperature and high-humid gas after drying the clothes into low-temperature and low-humid air and discharge it outside the device, improving the efficiency of clothes drying, ensuring the temperature and humidity of the outside air, ensuring the air quality entering the inner cylinder through the fresh air duct, reducing odors, improving control quality, and improving the efficiency of clothes drying.

[0138] Both the air inlet module 20 and the heat exchange component 10 can prevent the foam from overflowing caused by excessive use of washing powder.

[0139] Among them, 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 hot and humid air.

[0140] The cooling medium outlet in the air outlet module 12 is located at the bottom of the inclined lower housing. The bottom of the lower housing 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.

[0141] In the air inlet module 20, the opening of the air door 23 can be driven to realize the connection between the first air inlet and the first air outlet; and the size of the opening of the air door 23 driven by the driving part can be controlled according to requirements; the negative ions generated by the negative ion generator purify the air in the first area 2110, ensuring the hygiene of the clothes in the clothes washing device; and the negative ion generator can work when the air door 23 is opened, without causing waste of energy.

[0142] Embodiment 2:

[0143] See Figures 1-3 、 Figures 9-18 The present invention also provides a direct-discharge type clothing care device based on a fresh air system, including: a box body, an inner cylinder 31, an outer cylinder 32, an air inlet module 20 for sterilizing external fresh air, a heat exchange component 10 for cooling and dehumidifying hot and humid gas, a fresh air duct 1 for introducing external fresh air into the device, a connecting duct 6 for discharging the hot and humid gas in the device, and an exhaust air duct 2.

[0144] The box body constitutes the basic external structure of the device.

[0145] The inner cylinder 31 and the outer cylinder 32 are arranged inside the box body. The inner cylinder 3 is used to hold clothes. 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 air inlet is provided on the outer cylinder 32.

[0146] The fresh air duct 1, one end of the fresh air duct 1 is the 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 body enters the fresh air duct through the fresh air inlet. The other end of the fresh air duct 1 is communicated with the first air inlet of the air inlet module 20, and the external fresh air is introduced into the inner cylinder 31 after being sterilized by the air inlet module 20.

[0147] The connecting duct 6, one end of the connecting duct 6 is communicated with the first air outlet of the air inlet module 20, and the other end is communicated with the inner cylinder 31. The fresh air sterilized by the air inlet module 20 enters the inner cylinder 31 through the connecting duct 6.

[0148] The exhaust air duct 2, one end of the exhaust air duct 2 is the exhaust air inlet arranged on the outer cylinder, and the other end is communicated with the air path structure 122 of the air outlet module 12; the humid and hot air inside the inner cylinder first enters the outer cylinder 32 through the holes on the inner cylinder 31, then enters the exhaust air duct 2 from the exhaust air inlet, and enters the heat exchange component 10 through the exhaust air duct 2.

[0149] The circulation duct 5, one end of the circulation duct 5 is the ventilation port arranged on the outer cylinder 32, and the other end is communicated with the inner cylinder 31; preferably, a heating component 51 and a fan housing 52 are provided on the circulation duct 5. Under the action of the fan housing 52, the humid and hot air inside 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 is circulated back to the inner cylinder 31 after being heated by the heating component 51.

[0150] 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 air duct 2 from the exhaust air inlet on the outer cylinder 32, and enters the air outlet module 12 through the exhaust air duct 2. It can effectively prevent the laundry foam in the inner cylinder 31 from entering the exhaust air duct 2.

[0151] The inner cylinder 31 is communicated with the outer cylinder 32, and an exhaust air inlet is provided on the outer cylinder 32 to realize the connection between the inner cylinder 31 and 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 communicated with the exhaust air inlet arranged on the outer cylinder 32, and the other end is communicated with 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 device enters the air path structure 122 of the heat exchange component 10 through the exhaust air duct 2, and is discharged to the room after being cooled and dehumidified by the heat exchange component 10.

[0152] To achieve controlled communication with the inner cylinder, the air intake module 20 is provided with a damper. When the damper is opened, fresh indoor air enters the inner cylinder 31 after being sterilized by the air intake module 20.

[0153] In the existing laundry devices, generally there is no fresh air duct 1 for external fresh air to enter the inner cylinder 31, nor is there an exhaust duct 2 for discharging the humid and hot air from the inner cylinder 31 and the outer cylinder 32 to the outside of the device.

[0154] Even if the fresh air duct 1 and the exhaust duct 2 of the fresh air system are added and the humid and hot air is directly discharged outdoors, 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 inability to ensure the long-term quality of the air quality, and easily causing damage and pollution to the clothes during drying. In this application, the other end of the exhaust duct 2 is connected to the air path structure 121 of the air outlet module 12, and the humid and hot air is discharged outside 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 odors, improving the control quality, and achieving efficient drying. And an air intake module 20 is provided at the fresh air duct 1, which can achieve controlled communication with the inner cylinder, laying a foundation for subsequent automatic control. And when the damper is opened, fresh indoor air enters the inner cylinder 31 after being sterilized by the air intake module 20, ensuring the air quality of the inner cylinder in the device and reducing odors.

[0155] Specifically, the heat exchange component 10 includes an air outlet module 12 and an air outlet box body for accommodating the air outlet module. The air outlet 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 for water-vapor separation, that is, the air outlet module is a water-vapor separation air outlet module.

[0156] 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.

[0157] 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 122, accelerating the cooling rate of the gas to be cooled in the air path structure 122.

[0158] 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 second partition plate 1222. The second 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 circuit 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 circuit structure 121 to cool the high - temperature and high - humidity gas and then is discharged.

[0159] Preferably, the edge of the heat conducting plate 123 is bent towards the water circuit 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 circuit structure 121 is located in the groove.

[0160] 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.

[0161] The heat conducting plate 123 is provided with a mounting hole 1233. After the air outlet module 12 is placed in the lower housing 13, it is installed in the mounting hole 1233 by screws or bolts to realize the fixed installation of the heat conducting plate 123 and the lower housing 13.

[0162] 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.

[0163] The water circuit structure 121 includes: a plurality of upper fins 1211. The upper fins 1211 are rectangular sheet - like structures without bending. 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. The bottom of the upper fins 1211 is integrally formed on the heat conducting plate 123, and all the upper fins 1211 are parallel to each other, so that the water channels formed between the upper fins 1211 cover the entire heat conducting plate 123, increasing the contact area between the cooling medium and the heat conducting plate 123.

[0164] 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 circuit structure 121 is located in the groove.

[0165] 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.

[0166] 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. The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211, and 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.

[0167] Refer to 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 perpendicular 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.

[0168] Preferably, refer to 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.

[0169] 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.

[0170] 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.

[0171] Preferably, each lower fin 1221 is arc-shaped, and an air duct is formed between two adjacent lower fins 1221. Preferably, the air duct is also arc-shaped.

[0172] 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.

[0173] 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 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.

[0174] 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.

[0175] Preferably, the inner arc of the lower fin 1221 faces the second air inlet 132 of the air outlet module 12, so that the air entering the air duct from the second 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.

[0176] 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 second 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 second air outlet 131.

[0177] The air outlet 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 a second air inlet 132, a second 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 second air outlet 131, so that the shape of the second air outlet 131 is semi-circular. The baffle is located at the bottom of the second air outlet 131 to prevent water from being discharged.

[0178] The heat conducting plate 123 is made of a heat conducting material, such as metal and alloy. The upper housing 11 and the lower housing 13 are made of plastic or metal.

[0179] The second air inlet 132 is higher than the second air outlet 131, and the second air inlet 132 is larger than the second air outlet 131 to prevent the disorder of the air flow. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to discharge the condensed water in time, 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 the dehumidification of the humid and hot air.

[0180] 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 on the inclined bottom.

[0181] 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.

[0182] 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 to discharge the cooling medium in time, so as to avoid excessive condensed water content in the air outlet module 12 and prevent the condensed water from accumulating 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.

[0183] 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.

[0184] The second air inlet 132 and the second air outlet 131 are located on two adjacent side walls. The arc surface of the lower fin 1221 faces the second air inlet 132, so that the air entering the air duct from the second 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 second air outlet 131 is located on the side wall adjacent to the second air inlet 132.

[0185] Both the upper housing 11 and the lower housing 13 are in a groove structure. After the upper housing 11 and the lower housing 13 are fixedly installed, a receiving 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.

[0186] After the upper housing 11 and the lower housing 13 are snap-fitted, the cooling medium inlet 111 is located between the baffle 124 and the upper fin 1211. The second air inlet 132 is higher than the second 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, 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 drying device enters the air channel structure 122 through the second air inlet 132, flows into each air duct after being impacted by the lower fin 1221, and is discharged from the second air outlet 131 after being cooled by the heat conduction plate 123 into low-temperature and low-humidity air.

[0187] 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 second air inlet 132, and is discharged into the room as low-temperature and low-humidity air after being cooled and dehumidified by the heat conduction plate 123 from the second air outlet 131.

[0188] Reference Figures 16-18 , the air inlet module 20, includes: an air inlet box body, a damper 23, a driving member 25, and an anion generator.

When the damper 23 is in the open state, the first air inlet 2121 and the first air outlet 2111 are communicated.

[0191] The first air inlet 2121 is connected to the fresh air outside the device, and the first air outlet 2111 is connected to the inner cylinder of the clothing drying device.

[0192] The bottom box 21 includes a first region 2110 and a second region 2120. The bottom box 21 is provided with a first partition 2130, and a ventilation opening 2131 is provided on the first partition 2130, that is, a ventilation opening 2131 is provided between the first region 2110 and the second region 2120; the air damper 23 is installed in the second region 2120, and the air damper 23 is rotatably installed on the box body. When the air damper 23 is in the closed state, it hermetically covers the ventilation opening 2131. In other embodiments, the air damper is installed on the box body, and the air damper can achieve a linear displacement on the box body to open the ventilation opening 2131.

[0193] Preferably, the first air inlet 2121 is located in the second region 2120, the first air outlet 2111 is located in the first region 2110, and the air damper 23 is located in the second region 2120, that is, close to the first air inlet 2121. A negative ion generator (not shown in the figure) is connected to the first region 2110 through a pipeline, and the negative ions generated by the negative ion generator dust and purify the air in the first region 2110.

[0194] A negative ion generator is a device that generates air negative ions. After the input direct current or alternating current is processed by the EMI processing circuit and the lightning protection circuit, through a pulsed circuit, overvoltage and current limiting; high and low voltage isolation and other circuits are raised to an alternating high voltage, and then a pure direct current negative high voltage is obtained after rectification and filtering by special-grade electronic materials. The direct current negative high voltage is connected to the release tip made of metal or carbon element, and a high corona is generated by the tip direct current high voltage, and a large number of electrons are released at high speed. Since electrons cannot exist in the air for a long time, they will immediately be captured by oxygen molecules in the air, thereby generating air negative ions.

[0195] The air damper 23 includes an air damper body 231, a sealing ring 232, and a mounting shaft 233.

[0196] The air damper body 231, the sealing ring 232, and the mounting shaft 233 can be integrally formed; alternatively, the air damper body 231 and the mounting shaft 233 are integrally formed, and the sealing ring 232 is fixedly installed on the air damper body 231. Preferably, the sealing ring 232 is a flexible material that can achieve sealing. The sealing ring 232 is located on the side of the air damper body 231 facing the ventilation opening 2131.

[0197] The sealing ring 232 is located on the side of the air damper body 231 facing the ventilation opening 2131. Preferably, the air damper is rotatably installed on the box body, the air damper 23 opens in the direction of the first air inlet 2121, and when the air damper 23 is closed, the wind at the first air inlet 2121 presses the air damper body 231 and the sealing ring 232 tightly against the first partition 2130.

[0198] Preferably, a rotation hole is provided on the bottom box 21, and the mounting shaft 233 is rotatably mounted in the rotation hole to rotatably mount the air door 23 on the bottom box 21. Preferably, the air door 23 rotates towards the air inlet, that is, the air door opens towards the direction of the first air inlet 2121. When the air door 23 is closed, the fresh air entering from the first air inlet 2121 can exert pressure on the air door body 231, so that the air door body 231 presses the sealing ring 232 to seal the air door, ensuring that when the air door is closed, the air inlet module does not allow air to pass through.

[0199] The driving member 25 is fixedly mounted on the air inlet box body. Preferably, the driving member 25 is fixedly mounted on the outer wall of the bottom box 21. The air door 23 is power-coupled with the driving member 25. In this embodiment, the driving member 25 drives the mounting shaft 233 of the air door 23 to rotate in the mounting hole to open and close the air door 23.

[0200] In other embodiments, the air door is mounted on the box body, and the air door can achieve linear displacement on the box body to open the ventilation opening 2131, and the driving member 25 drives the air door 23 to achieve linear motion.

[0201] The air inlet module 20 further includes a sensor for detecting the position of the air door. When it is detected that the air door is in the open position, the negative ion generator starts to work.

[0202] The air inlet module 20 further includes an angle detection device for obtaining the opening and closing angle of the air door body. The angle detection device includes: a magnet mounted on the mounting shaft 233 and a Hall sensor opposite to the magnet.

[0203] The magnet mounted on the mounting shaft 233 rotates with the mounting shaft 233, and the magnetic field of the magnet along the direction of the mounting shaft 233 changes as the magnet rotates;

[0204] The Hall sensor opposite to the magnet can detect the opening and closing angle of the air door body 231 according to the change of the magnetic field.

[0205] The magnet rotates with the air door, and the magnetic field along the main shaft body direction also changes with the rotation. The Hall sensor detects the opening and closing angle of the air door body 231 according to the change of the magnetic field, and can quickly, accurately and efficiently detect the opening and closing angle.

[0206] The Hall sensor is an angle Hall sensor. The angle Hall sensor detects the opening and closing angle of the air door according to the change of the magnetic field. Specifically, the angle Hall sensor converts the spatial position change amount of the N and S magnetic fields of the magnet into the angle change amount of the main shaft body, and outputs the angle change amount to the main control unit in the form of a digital quantity.

[0207] When the opening angle of the air door body is greater than the angle threshold, the negative ion generator operates.

[0209] Both the air inlet module 20 and the air heat exchange component 10 can prevent foam overflow caused by excessive use of washing powder.

[0210] Among them, the design of the water path 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 path structure 122 increases the channel length of the gas, improving the cooling efficiency of the hot and humid air.

[0211] The cooling medium outlet in the air outlet module 12 is located at the bottom of the inclined lower housing. The bottom of the lower housing includes a plurality of inclined surfaces to timely discharge the cooling medium, avoid condensate accumulation at the bottom, and improve the dehumidification efficiency.
