Abstract
Description
Technical Field
[0001] This invention relates to the field of drying technology for garment care, and more specifically to a high-efficiency drying system. Background Technology
[0002] Currently available clothing drying devices, such as dryers and washer-dryer combos, mainly use condenser-type circulating drying. The principle is generally that air is heated by a heater and enters the drying drum. Under the influence of the hot air, the water on the clothes evaporates and mixes with the air to form humid air. This humid air then enters the condenser, where it condenses into condensate and dry gas after passing through a cooling medium. The dry gas is then heated again before entering the drum, and this cycle continues to dry the clothes. However, this air circulation method has problems such as strong odors, high temperatures, and high condensation water consumption. Furthermore, the high circulation temperature can damage clothing. Therefore, existing clothing drying devices need to be optimized.
[0003] Existing direct-venting technology introduces fresh air from the outside and exhausts it directly from the dryer after drying. This method is energy-intensive, especially in low outside temperatures, making it uneconomical. Furthermore, the dried air is typically hot and humid; directly venting this hot, humid air from the inner drum into the room causes excessively high humidity and temperature. This excessively hot and humid indoor air then re-enters the inner drum through the fresh air duct, compromising long-term air quality and potentially damaging and contaminating clothes during the drying process. Summary of the Invention

[0043] An air intake module installed at the fresh air duct allows fresh air from outside the inner drum to enter for sterilization, and controls the opening and size of the damper as needed. A heat exchange component installed at the exhaust duct transforms the high-temperature, high-humidity air from the dried clothes into low-temperature, low-humidity air, which is then discharged outside the device. This improves the efficiency of clothes drying, ensures the temperature and humidity of the outside air, and guarantees the air quality entering the inner drum through the fresh air duct, reducing odors, improving control quality, and increasing the efficiency of clothes drying.
[0044] Both the air intake module and the heat exchange component can prevent foam overflow caused by adding too much laundry detergent.

[0076] Next, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that terms such as "having," "comprising," and "including" as used herein do not imply the presence or addition of one or more other elements or combinations thereof.
[0077] Example 1:
[0078] See Figures 1-8 , Figures 14-18 The present invention also provides a high-efficiency drying system, comprising: 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 humid and hot gas, a condenser 4 for condensing humid and hot gas, a fresh air duct 1 for introducing external fresh air into the device, a connecting duct 6 for connecting the air inlet module 20 and the inner cylinder 31, and an exhaust duct 2 for discharging humid and hot gas from the device.
[0079] The housing constitutes the basic external structure of the device.
[0080] The inner cylinder 31 and the outer cylinder 32 are housed inside the box. The inner cylinder 31 is used to hold clothes, and the inner cylinder 31 is located inside the outer cylinder 32 and communicates with the outer cylinder 32 through a hole (not shown in the figure) on the inner cylinder 31. The hot and humid air inside the inner cylinder 31 can enter the outer cylinder 32. The outer cylinder 32 is provided with an exhaust inlet.
[0081] The fresh air duct 1 has a fresh air inlet at one end, located on the front or top panel of the enclosure, connecting to external fresh air. External air enters the duct through this inlet. The other end connects to the first air inlet 2121 of the air intake module 20. External fresh air, after being sterilized by the air intake module 20, enters the inner cylinder 31 and then connects to the condenser 4. In short, the fresh air duct 1 delivers external fresh air to the condenser 4 via the inner cylinder 31. Preferably, an air filter is installed on the fresh air duct 1 to purify the air entering the duct from inside the enclosure and / or from outside. Preferably, a small fan is installed on the fresh air duct 1 to increase the air intake of the enclosure.
[0082] Connecting air duct 6, one end of which is connected to the first air outlet 2111 of air inlet module 20, and the other end is connected to inner cylinder 31. Fresh air that has been sterilized by air inlet module 20 enters inner cylinder 31 through connecting air duct 6, enters outer cylinder 32 through inner cylinder 31, and then enters heat exchange component 10 and condenser 4.
[0083] The exhaust duct 2 has an exhaust inlet at one end located on the outer cylinder and the other end connected to the air passage structure 122 of the heat exchange component 10. The humid and hot air in the inner cylinder 31 first enters the outer cylinder 32 through the hole on the inner cylinder 31, and then enters the exhaust duct 2 through the exhaust inlet, and enters the heat exchange component 10 through the exhaust duct 2.
[0084] The circulating air duct 5 is connected at one end to the condenser 4 and at the other end to the inner cylinder 31. After the air passing through the condenser 4 is condensed, it is supplied into the inner cylinder 31 by the circulating air duct 5.
[0085] Preferably, the circulating air duct 5 is equipped with a heating element 51 and a fan casing 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 condenser 4 through the holes on the outer cylinder 32. The gas condensed by the condenser 4 enters the circulating air duct 5 under the action of the fan casing 52, is heated by the heating element 51, and then circulates back to the inner cylinder 31 to dry the clothes. At the same time, under the action of the fan casing 52, the fresh air entering the inner cylinder 31 through the fresh air duct 1 enters the condenser 4 to participate in the circulation. The fresh air entering the inner cylinder 31 increases the air pressure in the inner cylinder, causing the humid and hot air in the cylinder to enter the heat exchange element 10 through the exhaust inlet on the outer cylinder.
[0086] Condenser 4 connects to the outer cylinder and is used to condense the humid hot air entering the condenser 4 from the outer cylinder 32. The humid hot air in the inner cylinder 3 enters the space between the inner and outer cylinders through holes on the inner cylinder 3, and then enters the condenser 4 through holes on the outer cylinder. The condenser 4 condenses the humid hot air entering the condenser from the outer cylinder. The other end of the condenser is connected to the inner cylinder 3, so that the condensed air is heated by the heating element 51 in the circulating air duct 5 under the action of the fan casing 52 before being supplied to the inner cylinder 3. The condensed water flows into the drain pump 71 with the condensate. It is then discharged through the drain pipe 7 by the action of the drain pump 71.
[0087] Preferably, the cooling medium outlet 133 on the heat exchange component 10 is connected to the condenser 4. The cooling water enters the condenser 4 after passing through the water passage structure of the air outlet module 12 and is reused by the condenser 4, which improves the water utilization rate. At the same time, the heat exchange component 10 directly discharges the moisture, which increases the drying efficiency and shortens the drying time.
[0088] The hot and humid air in the inner drum 31 enters the outer drum 32 through the upper hole of the inner drum 31, and then enters the exhaust duct 2 through the exhaust inlet on the outer drum 32, and then enters the air outlet module 12 through the exhaust duct 2. This effectively prevents the washing foam in the inner drum 31 from entering the exhaust duct 2.
[0089] The inner cylinder 31 is connected to the outer cylinder 32, and the outer cylinder 32 is provided with an exhaust inlet to connect the inner cylinder 31 to the exhaust duct, so that the hot and humid air in the inner cylinder 31 is discharged outside the device after being processed by the heat exchange component 10. One end of the exhaust duct 2 is connected to the exhaust inlet located in the outer cylinder 32, and the other end is connected to the air passage structure 122 in the heat exchange component 10. The cooling medium flowing in the water passage structure 121 exchanges heat with the heat conduction plate 123. The hot and humid air in the device enters the air passage structure 122 of the heat exchange component 10 through the exhaust duct 2, and is discharged into the room after being cooled and dehumidified by the heat exchange component 10.
[0090] In order to achieve control connection with the inner cylinder, the air inlet module 20 is equipped with a damper. When the damper is open, the indoor fresh air enters the inner cylinder 31 after being sterilized by the air inlet module 20.
[0091] In existing drying devices, a condenser drying method is generally used, which involves installing only a condenser. After the hot and humid air is condensed by the condenser 4, it is heated by the heating element 51 through the circulating air duct 5 and then circulated into the inner drum 31. This cycle is repeated to dry the clothes. However, using only the condenser drying method results in a long drying time and high temperature, which can easily damage the clothes.
[0092] Even with the addition of a fresh air duct 1 and an exhaust duct 2 to the fresh air system, directly expelling hot and humid air to the outside would result in excessively high indoor humidity and temperature. This excessively hot and humid indoor air then entering the inner cylinder 31 via the fresh air duct 1 would compromise air quality, potentially causing damage and contamination to clothes during drying. This application addresses this by connecting the exhaust duct 2 to the air outlet module 12 via an airflow structure 121. Hot and humid air is processed by the heat exchange component 10 before being discharged outside the device, ensuring the temperature and humidity of the outside air and guaranteeing the air quality entering the inner cylinder via the fresh air duct. This reduces odors, improves control quality, and achieves efficient drying. Furthermore, an air inlet module 20 is installed at the fresh air duct 1, enabling control communication with the inner cylinder and laying the foundation for subsequent automated control. When the damper is open, indoor fresh air is sterilized by the air inlet module 20 before entering the inner cylinder 31, ensuring air quality within the inner cylinder and reducing odors.
[0093] Specifically, the heat exchange assembly 10 includes an air outlet module 12 and an air outlet housing that houses the air outlet module. The air outlet housing includes an upper shell 11 and a lower shell 13. In this embodiment, the heat exchange assembly 10 is a water-vapor separation heat exchange assembly, that is, the air outlet module is a water-vapor separation air outlet module.
[0094] The air outlet module 12 includes a water channel structure 121, a heat-conducting plate 123, and an air channel structure 122. Preferably, the water channel structure 121, the heat-conducting plate 123, and the air channel structure 122 are all made of thermally conductive materials.
[0095] The heat-conducting plate 123 is located between the water channel structure 121 and the air channel structure 122 of the air outlet module. Preferably, the water channel structure 121, the heat-conducting plate 123 and the air channel structure 122 are integrally formed, or the water channel structure 121 and the air channel structure 122 are welded to the heat-conducting plate 123.
[0096] Furthermore, the heat-conducting plate 123 separates the water channel structure 121 from the air channel structure 122, so that the water channel structure 121 and the air channel structure 122 are not connected. That is, the water channel structure 121 and the air channel structure 122 are isolated, so that the cooling water in the water channel structure 121 is not isolated from the gas to be cooled in the air channel structure. This ensures that the cooling water flows out at a faster speed, increases the contact area of the cooling water in the water channel structure, and ensures that the temperature of the cooling water can be reused.
[0097] The heat-conducting plate 123 is provided with a drain outlet 1231. Preferably, the drain outlet 1231 is located at the edge of the heat-conducting plate 123. The air duct structure 122 also includes a second partition 1222. The second partition 1222 is an extension of the heat-conducting plate in a direction away from the air duct structure and is located at the edge of the drain outlet, partially enclosing the drain outlet 1231 so that the drain outlet 1231 is directly connected to the cooling medium outlet 133 on the air outlet box. The cooling water introduced into the air outlet module 12 flows in the water channel and enters the cooling medium outlet 133 through the drain outlet 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.
[0098] Preferably, the edge of the heat-conducting plate 123 is bent toward 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.
[0099] The baffle 124 includes a first baffle 1241, a second baffle 1242, a third baffle 1243 and a fourth baffle 1244, wherein 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 and the third baffle 1243 are parallel.
[0100] 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 achieve the fixed installation of the heat-conducting plate 123 and the lower housing 13.
[0101] The first baffle 1241 has a semi-circular notch 12411. The upper housing 11 is installed after the lower housing 13, and the notch 12411 is located at the cooling medium inlet 111.
[0102] The water channel structure 121 includes several upper fins 1211, each upper fin being a rectangular, sheet-like structure without bends, with water channels formed between adjacent upper fins 1211. The upper fins 1211 are parallel to each other, and the spacing between adjacent upper fins 1211 is equal. The bottom of each upper fin 1211 is integrally formed on a heat-conducting plate 123. All 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.
[0103] Preferably, the upper fin 1211 is located in the groove where the baffle 124 and the heat-conducting plate 123 form an opening, that is, the water channel structure 121 is located in the groove.
[0104] All the upper fins 1211 are parallel to each other, and the connecting ends of the upper fins 1211 are either the first baffle 1241 or the third baffle 1243. Two adjacent upper fins 1211 are fixedly connected to or integrally formed with the first baffle 1241 and the third baffle 1243, respectively, to form a continuously curved waterway.
[0105] See Figure 6 and Figure 7 The angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle or an acute angle. This can be understood as the upper fin 1211 being perpendicular to the first baffle 1241 or the third baffle 1243, or inclined to the first baffle 1241 or 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.
[0106] refer to Figure 6 The upper fin 1211 forms a right angle with either the first baffle 1241 or the third baffle 1243, meaning the upper fin 1211 is perpendicular to either the first baffle 1241 or the third baffle 1243. The first baffle 1241 or the third baffle 1243 serves as the connecting end of the upper fin 1211, meaning the upper fin 1211 is perpendicular to the connecting end of the upper fin 1211. 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 volume of the cooling medium in the water channel structure per unit time, and improving heat exchange efficiency.
[0107] Preferably, refer to Figure 7 The angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is an acute angle, meaning the upper fin 1211 is inclined to the first baffle 1241 or the third baffle 1243. The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211, meaning the upper fin 1211 is inclined to the connecting end of the upper fin 1211. After the upper shell 11 and the lower shell 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, causing the cooling medium to flow into the remaining water channels. The water flow impacting the upper fin 1211 is more conducive to the heat transfer of the cooling water, improving the efficiency of heat exchange.
[0108] 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 increase the contact area between the cooling medium and the heat-conducting plate 123. See [reference needed]. Figure 6All parts of the heat-conducting plate 123 are in contact with the cooling medium, and the sheet-like structure of the upper fin 1211 with no bending design reduces manufacturing costs.
[0109] The airflow structure 122 includes: a plurality of lower fins 1221 and a second baffle 1222, at least two of the lower fins 1221 are arc-shaped lower fins, and an arc-shaped airflow duct is formed between adjacent arc-shaped lower fins.
[0110] 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.
[0111] The lower fins are fixed to the heat-conducting plate 123 in the air outlet module 12, and the heat-conducting plate 123 is provided with a drain outlet 1231. The second partition 1222 surrounds the drain outlet 1231.
[0112] Preferably, in this embodiment, since the heat-conducting plate 123 is approximately square, the dimensions of each of the plurality of lower fins 1221 are different. Specifically, the spacing between the plurality of lower fins 1221 is equal, that is, the width of the water channels formed by the lower fins 1221 is the same. The curvature of the plurality of lower fins 1221 is the same, so that the plurality of lower fins 1221 are parallel to each other, with a curvature of 10 degrees to 90 degrees.
[0113] Specifically, see Figure 2 The lower fin 1221 includes a root 12211 and an end 12212. The root 12211 is fixed to the heat-conducting 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. This saves material while ensuring structural strength.
[0114] 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 air contact area and improving the cooling speed of the humid and hot air.
[0115] Preferably, in this embodiment, reference Figure 4 There are seven lower fins 1221, with the inner arc of the first lower fin facing the second air inlet 132 of the air outlet module 12, and the air duct formed between the sixth and seventh lower fins facing the second air outlet 131.
[0116] The air outlet box includes an upper housing 11 and a lower housing 13. The upper housing 11 is provided with a cooling medium inlet 111, and the lower housing 13 is provided with a second air inlet 132, a second air outlet 131, and a cooling medium outlet 133. The second air outlet 131 is provided with a semi-circular baffle, making the shape of the second air outlet 131 semi-circular. The baffle is located at the bottom of the second air outlet 131 to prevent water from being discharged.
[0117] The heat-conducting plate 123 is made of a heat-conducting material, such as metal or alloy. The upper housing 11 and the lower housing 13 are made of plastic or metal.
[0118] 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 airflow turbulence. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to discharge condensate in a timely manner, so as to prevent excessive condensate content in the air outlet module 12, which would lead to an increase in humidity in the air outlet module 12 and be detrimental to the dehumidification of hot and humid air.
[0119] The lower housing 13 includes side walls and a bottom, the bottom being an inclined bottom, and the cooling medium outlet 133 is located at the inclined bottom.
[0120] 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, with their upper ends connected to the sidewall and their lower ends 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 sidewall. A transition slope 137 is also provided between the sidewall and the second inclined surface 135.
[0121] The cooling medium outlet 133 is located on the second inclined surface 135. Due to the guiding effect of gravity, the condensate will eventually fall to 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 a timely manner, so as to avoid excessive condensate content in the air outlet module 12, and at the same time, to avoid condensate accumulation at the bottom, which would increase the humidity of the air outlet module 12 and be detrimental to the dehumidification of hot and humid air.
[0122] Furthermore, 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 streamlined, reducing the noise of the cooling medium in the heat exchange component 10.
[0123] 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, causing the air entering the air duct from the second air inlet 132 to impact the lower fin 1221 before entering the various air ducts, increasing the air contact area and improving the cooling rate of hot and humid 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.
[0124] Both the upper housing 11 and the lower housing 13 have a groove structure. After the upper housing 11 and the lower housing 13 are fixedly installed, they form a receiving space to accommodate the air outlet module 12. The upper housing 11 and the lower housing 13 can be fastened together. Preferably, the upper housing 11 can be screwed to the air outlet module 12 to achieve a fixed fastening.
[0125] After the upper shell 11 and the lower shell 13 are fastened 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. 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 hot and humid air in the air channel structure 122 through the heat conduction effect of the heat conduction plate 123. The cooling water flows into the lower shell 13 through the drain outlet 1231 and is discharged from the cooling medium outlet 133 at the bottom of the lower shell 13. At the same time, the hot and humid air discharged from the clothes drying device enters the air channel structure 122 through the second air inlet 132, flows into each air channel after being impacted by the lower fin 1221, and is cooled into low-temperature and low-humidity air by the heat conduction plate 123 before being discharged from the second air outlet 131.
[0126] In short, the cooling medium enters the water channel structure 121 through the cooling medium inlet, and carries away the heat from the heat-conducting plate 123, flowing out from the cooling medium outlet 133 at the bottom of the lower shell 13. The heat-conducting plate 123 realizes the heat exchange between the cooling water in the water channel structure 121 and the humid air in the air channel structure 122. The humid air in the inner cylinder 31 enters the exhaust duct 2 through the exhaust inlet on the outer cylinder 32, and then enters the air channel structure 122 through the second air inlet 132. After being cooled and dehumidified by the heat-conducting plate 123, it becomes low-temperature, low-heat air and is discharged from the room through the second air outlet 131.
[0127] refer to Figures 16-18 The air intake module 20 includes: an air intake box, an air damper 23, a drive unit 25, and a negative ion generator.
[0128] The air inlet box includes a bottom box 21 and a top cover 22, which are fastened together. Preferably, the bottom box 21 has a lower fastening part, and the top cover 22 has an upper fastening part, which are fastened together to seal the box.
[0129] The bottom box 21 of the air inlet box is provided with a first air inlet 2121 and a first air outlet 2111; the damper 23 is rotatably mounted on the bottom box 21 of the air inlet box; 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 enables communication between the first air inlet 2121 and the first air outlet 2111.
[0130] The first air inlet 2121 connects to the external fresh air of the device, and the first air outlet 2111 connects to the inner drum of the clothes drying device.
[0131] The base box 21 includes a first region 2110 and a second region 2120. The base box 21 is provided with a first partition 2130, and the first partition 2130 is provided with a ventilation opening 2131, that is, a ventilation opening 2131 is provided between the first region 2110 and the second region 2120. A damper 23 is installed in the second region 2120. The damper 23 is rotatably installed on the box body. When the damper 23 is in the closed state, it seals and covers the ventilation opening 2131. In other embodiments, the damper is installed on the box body, and the damper can achieve linear displacement on the box body to open the ventilation opening 2131.
[0132] 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 damper 23 is located in the second region 2120, i.e., 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 pipe, and the negative ions generated by the negative ion generator purify the air in the first region 2110 by removing dust.
[0133] A negative ion generator is a device that generates negative air ions. The device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit. Then, it is stepped up to high AC voltage via a pulse circuit, overvoltage current limiting, and high / low voltage isolation. After rectification and filtering by special-grade electronic materials, a pure DC negative high voltage is obtained. This DC negative high voltage is connected to a release tip made of metal or carbon. The high voltage at the tip generates a high corona discharge, rapidly releasing a large number of electrons. Since electrons cannot exist in the air for long, they are immediately captured by oxygen molecules in the air, thus generating negative air ions.
[0134] The damper 23 includes a damper body 231, a sealing ring 232, and a mounting shaft 233.
[0135] The damper body 231, sealing ring 232, and mounting shaft 233 can be integrally formed; alternatively, the damper body 231 and mounting shaft 233 can be integrally formed, with the sealing ring 232 fixedly installed on the damper body 231. Preferably, the sealing ring 232 is a flexible material capable of achieving a seal. The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131.
[0136] The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131. Preferably, the damper is rotatably mounted on the housing, and the damper 23 opens towards the first air inlet 2121. When the damper 23 is closed, the airflow from the first air inlet 2121 causes the damper body 231 and the sealing ring 232 to press tightly against the first partition 2130.
[0137] Preferably, the base box 21 is provided with a rotating hole, and the mounting shaft 233 is rotatably installed in the rotating hole to realize the rotatable mounting of the damper 23 on the base box 21. Preferably, the damper 23 rotates in the direction of the air inlet, that is, the damper opens in the direction of the first air inlet 2121. When the damper 23 is closed, the fresh air entering from the first air inlet 2121 can apply pressure to the damper body 231, so that the damper body 231 squeezes the sealing ring 232 to seal the damper, ensuring that the air intake module does not enter when the damper is closed.
[0138] The drive component 25 is fixedly mounted on the air inlet box. Preferably, the drive component 25 is fixedly mounted on the outer wall of the bottom box 21. The damper 23 is dynamically coupled to the drive component 25. In this embodiment, the drive component 25 drives the mounting shaft 233 of the damper 23 to rotate within the mounting hole to open and close the damper 23.
[0139] In other embodiments, the damper is mounted on the housing and can achieve linear displacement on the housing to open the vent 2131. The drive member 25 drives the damper 23 to achieve linear movement.
[0140] The air intake module 20 also includes a sensor for detecting the position of the damper. The negative ion generator only starts working when the damper is detected to be in the open position.
[0141] The air intake module 20 also includes an angle detection device, which is used to obtain the opening and closing angle of the damper body. The angle detection device includes: a magnet mounted on the mounting shaft 233 and a Hall sensor opposite to the magnet.
[0142] 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 with the rotation of the magnet;
[0143] The Hall sensor, which is opposite to the magnet, can detect the opening and closing angle of the damper body 231 based on the change in the magnetic field.
[0144] As the magnet rotates with the damper, its magnetic field along the main shaft changes with the rotation. The Hall sensor detects the opening and closing angle of the damper body 231 based on the change in the magnetic field, enabling it to detect the opening and closing angle quickly, accurately, and efficiently.
[0145] The Hall sensor described is an angle Hall sensor. The angle Hall sensor detects the opening and closing angle of the damper based on the change of magnetic field. Specifically, the angle Hall sensor converts the spatial position change of the N and S magnetic fields of the magnet into the angle change of the main shaft body, and outputs the angle change in the form of a digital quantity to the main control unit.
[0146] The negative ion generator operates when the opening angle of the damper body exceeds a certain threshold. This means the negative ion generator can only function when the damper body is opened to a certain angle, laying the foundation for subsequent automated control.
[0147] The present invention provides a new high-efficiency drying system that integrates condensation drying and direct discharge drying. The heat exchange component 10 directly discharges the moisture, which improves the condensation efficiency of the condenser and shortens the drying time. The cooling water in the heat exchange component 10 enters the condenser 4 through the water passage structure 121 and is reused by the condenser 4, which improves the water utilization rate.
[0148] The air intake module 20 installed at the fresh air duct 1 can introduce fresh air from outside the inner drum 31 for sterilization and control the opening of the damper 23 as needed; the heat exchange component 10 installed at the exhaust duct 2 can transform the high temperature and high humidity gas after clothes drying into low temperature and low humidity air and exhaust it to the outside of the device, which can improve the efficiency of clothes drying and ensure the temperature and humidity of the outside air, ensure the air quality entering the inner drum through the fresh air duct, reduce odors, improve control quality, and improve the efficiency of clothes drying.
[0149] Both the air intake module 20 and the heat exchange component 10 can prevent foam overflow caused by adding too much laundry detergent.
[0150] The design of the water channel structure 121 increases the contact area between the cooling medium and the heat-conducting plate 123, thereby improving cooling efficiency. Furthermore, the design of the air channel structure 122 increases the length of the gas passage, improving the cooling efficiency for hot and humid air.
[0151] The cooling medium outlet is located at the bottom of the inclined lower housing, which includes multiple inclined surfaces to discharge the cooling medium in a timely manner, prevent condensate from accumulating at the bottom, and improve dehumidification efficiency.
[0152] The air intake module 20 can drive the opening of the damper to connect the first air inlet and the first air outlet; and the opening size of the damper 23 can be controlled according to the needs of the drive component; the negative ions generated by the negative ion generator remove dust and purify the air in the first area, ensuring the hygiene of the clothes in the washing device; and the negative ion generator can work when the damper is open, without wasting energy.
[0153] Example 2:
[0154] See Figures 1-3, Figures 9-18 The present invention also provides a high-efficiency drying system, comprising: 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 humid and hot gas, a condenser 4, a fresh air duct 1 for introducing external fresh air into the device, a connecting air duct 6 for discharging humid and hot gas from the device, and an exhaust air duct 2.
[0155] The housing constitutes the basic external structure of the device.
[0156] The inner cylinder 31 and the outer cylinder 32 are housed inside the box. The inner cylinder 31 is used to hold clothes, and the inner cylinder 31 is located inside the outer cylinder 32 and communicates with the outer cylinder 32 through a hole (not shown in the figure) on the inner cylinder 31. The hot and humid air inside the inner cylinder 31 can enter the outer cylinder 32. The outer cylinder 32 is provided with an exhaust inlet.
[0157] The fresh air duct 1 has a fresh air inlet at one end, located on the front panel or top panel of the enclosure, connecting to external fresh air. External air enters the fresh air duct through this inlet. The other end of the fresh air duct 1 connects to the first air inlet 2121 of the air intake module 20, where external fresh air is sterilized before entering the inner cylinder 31. Preferably, an air filter is installed on the fresh air duct 1 to purify the air entering the enclosure and / or the air inside. Preferably, a small fan is installed on the fresh air duct 1 to increase the air intake of the enclosure.
[0158] Connecting air duct 6, one end of which is connected to the first air outlet 2111 of air inlet module 20, and the other end is connected to inner cylinder 31. Fresh air that has been sterilized by air inlet module 20 enters inner cylinder 31 through connecting air duct 6, enters outer cylinder 32 through inner cylinder 31, and then enters heat exchange component 10 and condenser 4.
[0159] The exhaust duct 2 has an exhaust inlet at one end located on the outer cylinder and the other end connected to the air passage structure 122 of the heat exchange component 10. The humid and hot air in the inner cylinder first enters the outer cylinder 32 through the hole on the inner cylinder 31, and then enters the exhaust duct 2 through the exhaust inlet, and enters the heat exchange component 10 through the exhaust duct 2.
[0160] The circulating air duct 5 is connected at one end to the condenser 4 and at the other end to the inner cylinder 31. After the air passing through the condenser 4 is condensed, it is supplied into the inner cylinder 31 by the circulating air duct 5.
[0161] Preferably, the circulating air duct 5 is equipped with a heating element 51 and a fan casing 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 condenser 4 through the holes on the outer cylinder 32. The gas condensed by the condenser 4 enters the circulating air duct 5 under the action of the fan casing 52, is heated by the heating element 51, and then circulates back to the inner cylinder 31 to dry the clothes. At the same time, under the action of the fan casing 52, the fresh air entering the inner cylinder 31 through the fresh air duct 1 enters the condenser 4 to participate in the circulation. The fresh air entering the inner cylinder 31 increases the air pressure in the inner cylinder, causing the humid and hot air in the cylinder to enter the heat exchange element 10 through the exhaust inlet on the outer cylinder.
[0162] Condenser 4 connects to the outer cylinder and is used to condense the humid hot air entering the condenser from the outer cylinder. The humid hot air in the inner cylinder 3 enters the space between the inner and outer cylinders through holes on the inner cylinder 3, and then enters the condenser 4 through holes on the outer cylinder. The condenser 4 condenses the humid hot air entering the condenser from the outer cylinder. The other end of the condenser is connected to the inner cylinder 3, so that the condensed air is heated by the heating element 51 in the circulating air duct 5 under the action of the fan casing 52 before being supplied to the inner cylinder 3. The condensed water flows into the drain pump 71 with the condensate. It is then discharged through the drain pipe 7 by the action of the drain pump 71.
[0163] Preferably, the cooling medium outlet 133 on the heat exchange component 10 is connected to the condenser 4. The cooling water enters the condenser 4 after passing through the water passage structure of the air outlet module 12 and is reused by the condenser 4, which improves the water utilization rate. At the same time, the heat exchange component 10 directly discharges the moisture, which increases the drying efficiency and shortens the drying time.
[0164] The hot and humid air in the inner drum 31 enters the outer drum 32 through the upper hole of the inner drum 31, and then enters the exhaust duct 2 through the exhaust inlet on the outer drum 32, and then enters the air outlet module 12 through the exhaust duct 2. This effectively prevents the washing foam in the inner drum 31 from entering the exhaust duct 2.
[0165] The inner cylinder 31 is connected to the outer cylinder 32, and the outer cylinder 32 is provided with an exhaust inlet to connect the inner cylinder 31 to the exhaust duct, so that the hot and humid air in the inner cylinder 31 is discharged outside the device after being processed by the heat exchange component 10. One end of the exhaust duct 2 is connected to the exhaust inlet located in the outer cylinder 32, and the other end is connected to the air passage structure 122 in the heat exchange component 10. The cooling medium flowing in the water passage structure 121 exchanges heat with the heat conduction plate 123. The hot and humid air in the device enters the air passage structure 122 of the heat exchange component 10 through the exhaust duct 2, and is discharged into the room after being cooled and dehumidified by the heat exchange component 10.
[0166] In order to achieve control connection with the inner cylinder, the air inlet module 20 is equipped with a damper. When the damper is open, the indoor fresh air enters the inner cylinder 31 after being sterilized by the air inlet module 20.
[0167] In existing drying devices, a condenser drying method is generally used, which involves installing only a condenser. After the hot and humid air is condensed by the condenser 4, it is heated by the heating element 51 through the circulating air duct 5 and then circulated into the inner drum 31. This cycle is repeated to dry the clothes. However, using only the condenser drying method results in a long drying time and high temperature, which can easily damage the clothes.
[0168] Even with the addition of a fresh air duct 1 and an exhaust duct 2 to the fresh air system, directly expelling hot and humid air to the outside would result in excessively high indoor humidity and temperature. This excessively hot and humid indoor air then entering the inner cylinder 31 via the fresh air duct 1 would compromise air quality, potentially causing damage and contamination to clothes during drying. This application addresses this by connecting the exhaust duct 2 to the air outlet module 12 via an airflow structure 121. Hot and humid air is processed by the heat exchange component 10 before being discharged outside the device, ensuring the temperature and humidity of the outside air and guaranteeing the air quality entering the inner cylinder via the fresh air duct. This reduces odors, improves control quality, and achieves efficient drying. Furthermore, an air inlet module 20 is installed at the fresh air duct 1, enabling control communication with the inner cylinder and laying the foundation for subsequent automated control. When the damper is open, indoor fresh air is sterilized by the air inlet module 20 before entering the inner cylinder 31, ensuring air quality within the inner cylinder and reducing odors.
[0169] Specifically, the heat exchange assembly 10 includes an air outlet module 12 and an air outlet housing that houses the air outlet module. The air outlet housing includes an upper shell 11 and a lower shell 13. In this embodiment, the heat exchange assembly 10 is a water-vapor separation heat exchange assembly, that is, the air outlet module is a water-vapor separation air outlet module.
[0170] The air outlet module 12 includes a water channel structure 121, a heat-conducting plate 123, and an air channel structure 122. Preferably, the water channel structure 121, the heat-conducting plate 123, and the air channel structure 122 are all made of thermally conductive materials.
[0171] The heat-conducting plate 123 is located between the water channel structure 121 and the air channel structure 122 of the air outlet module. Preferably, the water channel structure 121, the heat-conducting plate 123, and the air channel structure 122 are integrally formed, or the water channel structure 121 and the air channel structure 122 are welded to the heat-conducting plate 123. The heat-conducting plate 123 is provided with a plurality of through holes 1232, which connect the water channel structure 121 and the air channel structure 122, so that the cooling water in the water channel structure 121 mixes with the gas to be cooled in the air channel structure 122, thereby accelerating the cooling rate of the gas to be cooled in the air channel structure 122.
[0172] The heat-conducting plate 123 is provided with a drain outlet 1231. Preferably, the drain outlet 1231 is located at the edge of the heat-conducting plate 123. The airflow structure 122 also includes a second partition 1222, which extends from the heat-conducting plate in a direction away from the airflow structure and is located at the edge of the drain outlet, partially enclosing the drain outlet 1231 so that the drain outlet 1231 can directly communicate with the cooling medium outlet 133 on the housing. Preferably, the size of the drain outlet 1231 is larger than the size of the through hole 1232. After the cooling medium is introduced into the waterflow structure 121, a large amount of cooling medium is discharged from the drain outlet 1231, and a small amount of cooling medium flows from the waterflow structure 121 into the airflow structure 122 to cool the high-temperature and high-humidity gas before being discharged.
[0173] Preferably, the edge of the heat-conducting plate 123 is bent toward 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.
[0174] The baffle 124 includes a first baffle 1241, a second baffle 1242, a third baffle 1243 and a fourth baffle 1244, wherein 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 and the third baffle 1243 are parallel.
[0175] 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 achieve the fixed installation of the heat-conducting plate 123 and the lower housing 13.
[0176] The first baffle 1241 has a semi-circular notch 12411. The upper housing 11 is installed after the lower housing 13, and the notch 12411 is located at the cooling medium inlet 111.
[0177] The water channel structure 121 includes several upper fins 1211, each upper fin being a rectangular, sheet-like structure without bends, with water channels formed between adjacent upper fins 1211. The upper fins 1211 are parallel to each other, and the spacing between adjacent upper fins 1211 is equal. The bottom of each upper fin 1211 is integrally formed on a heat-conducting plate 123. All 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.
[0178] Preferably, the upper fin 1211 is located in the groove where the baffle 124 and the heat-conducting plate 123 form an opening, that is, the water channel structure 121 is located in the groove.
[0179] All the upper fins 1211 are parallel to each other, and the connecting ends of the upper fins 1211 are either the first baffle 1241 or the third baffle 1243. Two adjacent upper fins 1211 are fixedly connected to or integrally formed with the first baffle 1241 and the third baffle 1243, respectively, to form a continuously curved waterway.
[0180] See Figure 11 and Figure 12 The angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is a right angle or an acute angle. This can be understood as the upper fin 1211 being perpendicular to the first baffle 1241 or the third baffle 1243, or inclined to the first baffle 1241 or 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.
[0181] refer to Figure 11 The upper fin 1211 forms a right angle with either the first baffle 1241 or the third baffle 1243, meaning the upper fin 1211 is perpendicular to either the first baffle 1241 or the third baffle 1243. The first baffle 1241 or the third baffle 1243 serves as the connecting end of the upper fin 1211, meaning the upper fin 1211 is perpendicular to the connecting end of the upper fin 1211. 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 volume of the cooling medium in the water channel structure per unit time, and improving heat exchange efficiency.
[0182] Preferably, refer to Figure 12 The angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is an acute angle, meaning the upper fin 1211 is inclined to the first baffle 1241 or the third baffle 1243. The first baffle 1241 or the third baffle 1243 is the connecting end of the upper fin 1211, meaning the upper fin 1211 is inclined to the connecting end of the upper fin 1211. After the upper shell 11 and the lower shell 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, causing the cooling medium to flow into the remaining water channels. The water flow impacting the upper fin 1211 is more conducive to the heat transfer of the cooling water, improving the efficiency of heat exchange.
[0183] 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 increase the contact area between the cooling medium and the heat-conducting plate 123. See [reference needed]. Figure 6All parts of the heat-conducting plate 123 are in contact with the cooling medium, and the sheet-like structure of the upper fin 1211 with no bending design reduces manufacturing costs.
[0184] The airflow structure 122 includes: a number of lower fins 1221 and baffles 1222, at least two of the lower fins 1221 are arc-shaped lower fins, and an arc-shaped airflow duct is formed between adjacent arc-shaped lower fins.
[0185] 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.
[0186] The lower fins are fixed to the heat-conducting plate 123 in the air outlet module 12, and the heat-conducting plate 123 is provided with a drain outlet 1231. The partition plate 1222 surrounds the drain outlet 1231.
[0187] Preferably, in this embodiment, since the heat-conducting plate 123 is approximately square, the dimensions of each of the plurality of lower fins 1221 are different. Specifically, the spacing between the plurality of lower fins 1221 is equal, that is, the width of the water channels formed by the lower fins 1221 is the same. The curvature of the plurality of lower fins 1221 is the same, so that the plurality of lower fins 1221 are parallel to each other, with a curvature of 10 degrees to 90 degrees.
[0188] Specifically, see Figure 2 The lower fin 1221 includes a root 12211 and an end 12212. The root 12211 is fixed to the heat-conducting 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. This saves material while ensuring structural strength.
[0189] 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 air contact area and improving the cooling speed of the humid and hot air.
[0190] Preferably, in this embodiment, reference Figure 9 There are seven lower fins 1221, with the inner arc of the first lower fin facing the second air inlet 132 of the air outlet module 12, and the air duct formed between the sixth and seventh lower fins facing the second air outlet 131.
[0191] The air outlet box includes an upper housing 11 and a lower housing 13. The upper housing 11 is provided with a cooling medium inlet 111, and the lower housing 13 is provided with a second air inlet 132, a second air outlet 131, and a cooling medium outlet 133. The second air outlet 131 is provided with a semi-circular baffle, making the shape of the second air outlet 131 semi-circular. The baffle is located at the bottom of the second air outlet 131 to prevent water from being discharged.
[0192] The heat-conducting plate 123 is made of a heat-conducting material, such as metal or alloy. The upper housing 11 and the lower housing 13 are made of plastic or metal.
[0193] 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 airflow turbulence. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to discharge condensate in a timely manner, so as to prevent excessive condensate content in the air outlet module 12, which would lead to an increase in humidity in the air outlet module 12 and be detrimental to the dehumidification of hot and humid air.
[0194] The lower housing 13 includes side walls and a bottom, the bottom being an inclined bottom, and the cooling medium outlet 133 is located at the inclined bottom.
[0195] 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, with their upper ends connected to the sidewall and their lower ends 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 sidewall. A transition slope 137 is also provided between the sidewall and the second inclined surface 135.
[0196] The cooling medium outlet 133 is located on the second inclined surface 135. Due to the guiding effect of gravity, the condensate will eventually fall to 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 a timely manner, so as to avoid excessive condensate content in the air outlet module 12, and at the same time, to avoid condensate accumulation at the bottom, which would increase the humidity of the air outlet module 12 and be detrimental to the dehumidification of hot and humid air.
[0197] Furthermore, 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 streamlined, reducing the noise of the cooling medium in the heat exchange component 10.
[0198] 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, causing the air entering the air duct from the second air inlet 132 to impact the lower fin 1221 before entering the various air ducts, increasing the air contact area and improving the cooling rate of hot and humid 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.
[0199] Both the upper housing 11 and the lower housing 13 have a groove structure. After the upper housing 11 and the lower housing 13 are fixedly installed, they form a receiving space to accommodate the air outlet module 12. The upper housing 11 and the lower housing 13 can be fastened together. Preferably, the upper housing 11 can be screwed to the air outlet module 12 to achieve a fixed fastening.
[0200] After the upper shell 11 and the lower shell 13 are fastened 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. 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 hot and humid air in the air channel structure 122 through the heat conduction effect of the heat conduction plate 123. The cooling water flows into the lower shell 13 through the drain outlet 1231 and is discharged from the cooling medium outlet 133 at the bottom of the lower shell 13. At the same time, the hot and humid air discharged from the clothes drying device enters the air channel structure 122 through the second air inlet 132, flows into each air channel after being impacted by the lower fin 1221, and is cooled into low-temperature and low-humidity air by the heat conduction plate 123 before being discharged from the second air outlet 131.
[0201] In short, the cooling medium enters the water channel structure 121 through the cooling medium inlet, and carries away the heat from the heat-conducting plate 123, flowing out from the cooling medium outlet 133 at the bottom of the lower shell 13. The heat-conducting plate 123 realizes the heat exchange between the cooling water in the water channel structure 121 and the humid air in the air channel structure 122. The humid air in the inner cylinder 31 enters the exhaust duct 2 through the exhaust inlet on the outer cylinder 32, and then enters the air channel structure 122 through the second air inlet 132. After being cooled and dehumidified by the heat-conducting plate 123, it becomes low-temperature, low-heat air and is discharged from the room through the second air outlet 131.
[0202] refer to Figures 16-18 The air intake module 20 includes: an air intake box, an air damper 23, a drive unit 25, and a negative ion generator.
[0203] The air inlet box includes a bottom box 21 and a top cover 22, which are fastened together. Preferably, the bottom box 21 has a lower fastening part, and the top cover 22 has an upper fastening part, which are fastened together to seal the box.
[0204] The bottom box 21 of the air inlet box is provided with a first air inlet 2121 and a first air outlet 2111; the damper 23 is rotatably mounted on the bottom box 21 of the air inlet box; 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 enables communication between the first air inlet 2121 and the first air outlet 2111.
[0205] The first air inlet 2121 connects to the external fresh air of the device, and the first air outlet 2111 connects to the inner drum of the clothes drying device.
[0206] The base box 21 includes a first region 2110 and a second region 2120. The base box 21 is provided with a first partition 2130, and the first partition 2130 is provided with a ventilation opening 2131, that is, a ventilation opening 2131 is provided between the first region 2110 and the second region 2120. A damper 23 is installed in the second region 2120. The damper 23 is rotatably installed on the box body. When the damper 23 is in the closed state, it seals and covers the ventilation opening 2131. In other embodiments, the damper is installed on the box body, and the damper can achieve linear displacement on the box body to open the ventilation opening 2131.
[0207] 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 damper 23 is located in the second region 2120, i.e., 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 pipe, and the negative ions generated by the negative ion generator purify the air in the first region 2110 by removing dust.
[0208] A negative ion generator is a device that generates negative air ions. The device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit. Then, it is stepped up to high AC voltage via a pulse circuit, overvoltage current limiting, and high / low voltage isolation. After rectification and filtering by special-grade electronic materials, a pure DC negative high voltage is obtained. This DC negative high voltage is connected to a release tip made of metal or carbon. The high voltage at the tip generates a high corona discharge, rapidly releasing a large number of electrons. Since electrons cannot exist in the air for long, they are immediately captured by oxygen molecules in the air, thus generating negative air ions.
[0209] The damper 23 includes a damper body 231, a sealing ring 232, and a mounting shaft 233.
[0210] The damper body 231, sealing ring 232, and mounting shaft 233 can be integrally formed; alternatively, the damper body 231 and mounting shaft 233 can be integrally formed, with the sealing ring 232 fixedly installed on the damper body 231. Preferably, the sealing ring 232 is a flexible material capable of achieving a seal. The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131.
[0211] The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131. Preferably, the damper is rotatably mounted on the housing, and the damper 23 opens towards the first air inlet 2121. When the damper 23 is closed, the airflow from the first air inlet 2121 causes the damper body 231 and the sealing ring 232 to press tightly against the first partition 2130.
[0212] Preferably, the base box 21 is provided with a rotating hole, and the mounting shaft 233 is rotatably installed in the rotating hole to realize the rotatable mounting of the damper 23 on the base box 21. Preferably, the damper 23 rotates in the direction of the air inlet, that is, the damper opens in the direction of the first air inlet 2121. When the damper 23 is closed, the fresh air entering from the first air inlet 2121 can apply pressure to the damper body 231, so that the damper body 231 squeezes the sealing ring 232 to seal the damper, ensuring that the air intake module does not enter when the damper is closed.
[0213] The drive component 25 is fixedly mounted on the air inlet box. Preferably, the drive component 25 is fixedly mounted on the outer wall of the bottom box 21. The damper 23 is dynamically coupled to the drive component 25. In this embodiment, the drive component 25 drives the mounting shaft 233 of the damper 23 to rotate within the mounting hole to open and close the damper 23.
[0214] In other embodiments, the damper is mounted on the housing and can achieve linear displacement on the housing to open the vent 2131. The drive member 25 drives the damper 23 to achieve linear movement.
[0215] The air intake module 20 also includes a sensor for detecting the position of the damper. The negative ion generator only starts working when the damper is detected to be in the open position.
[0216] The air intake module 20 also includes an angle detection device, which is used to obtain the opening and closing angle of the damper body. The angle detection device includes: a magnet mounted on the mounting shaft 233 and a Hall sensor opposite to the magnet.
[0217] 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 with the rotation of the magnet;
[0218] The Hall sensor, which is opposite to the magnet, can detect the opening and closing angle of the damper body 231 based on the change in the magnetic field.
[0219] As the magnet rotates with the damper, its magnetic field along the main shaft changes with the rotation. The Hall sensor detects the opening and closing angle of the damper body 231 based on the change in the magnetic field, enabling it to detect the opening and closing angle quickly, accurately, and efficiently.
[0220] The Hall sensor described is an angle Hall sensor. The angle Hall sensor detects the opening and closing angle of the damper based on the change of magnetic field. Specifically, the angle Hall sensor converts the spatial position change of the N and S magnetic fields of the magnet into the angle change of the main shaft body, and outputs the angle change in the form of a digital quantity to the main control unit.
[0221] The negative ion generator operates when the opening angle of the damper body exceeds a certain threshold. This means the negative ion generator can only function when the damper body is opened to a certain angle, laying the foundation for subsequent automated control.
[0222] The present invention provides a new high-efficiency drying system that integrates condensation drying and direct discharge drying. The heat exchange component 10 directly discharges the moisture, thereby increasing the drying efficiency and shortening the drying time. The cooling water in the heat exchange component 10 enters the condenser 4 through the water passage structure 121 and is reused by the condenser 4, thereby improving the water utilization rate.
[0223] The air intake module 20 installed at the fresh air duct 1 can introduce fresh air from outside the inner drum 31 for sterilization and control the opening of the damper 23 as needed; the heat exchange component 10 installed at the exhaust duct 2 can transform the high temperature and high humidity gas after clothes drying into low temperature and low humidity air and exhaust it to the outside of the device, which can improve the efficiency of clothes drying and ensure the temperature and humidity of the outside air, ensure the air quality entering the inner drum through the fresh air duct, reduce odors, improve control quality, and improve the efficiency of clothes drying.
[0224] Both the air intake module 20 and the heat exchange component 10 can prevent foam overflow caused by adding too much laundry detergent.
[0225] The design of the water channel structure 121 increases the contact area between the cooling medium and the heat-conducting plate 123, thereby improving cooling efficiency. Furthermore, the design of the air channel structure 122 increases the length of the gas passage, improving the cooling efficiency for hot and humid air.
[0226] The cooling medium outlet is located at the bottom of the inclined lower housing, which includes multiple inclined surfaces to discharge the cooling medium in a timely manner, prevent condensate from accumulating at the bottom, and improve dehumidification efficiency.
[0227] The air intake module 20 can drive the opening of the damper to connect the first air inlet and the first air outlet; and the opening size of the damper 23 can be controlled according to the needs of the drive component; the negative ions generated by the negative ion generator remove dust and purify the air in the first area, ensuring the hygiene of the clothes in the washing device; and the negative ion generator can work when the damper is open, without wasting energy.
[0228] In some embodiments, the clothes drying device is a dryer or a washer-dryer combo. When it is a washer-dryer combo, it has a washing structure and washing function, and more preferably a drum-type washer-dryer combo.
[0229] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details.
