Description

Technical Field

[0001] The present invention relates to the technical field of drying for clothing care, and in particular to a water-gas separation heat exchange component and a clothing drying device. Background Art

[0002] Currently, existing clothes drying devices, such as dryers and washer-dryers, mainly adopt condensation cycle drying. The principle is generally that the air is heated by a heater and enters the drying drum. Under the action of the hot air, the water on the clothes evaporates and forms humid hot air with the air. The humid hot air then enters the condenser. The humid hot air is condensed into condensed water and dry gas after being acted upon by a cooling medium in the condenser. The dry gas is then heated by the heater and enters the drum. After this cycle, the purpose of drying the clothes is achieved. However, the use of air circulation has problems such as strong odor, high temperature, and large condensation water consumption. In addition, the high circulation temperature causes damage to the clothes. Therefore, it is necessary to optimize the existing clothes drying device and adopt a direct exhaust method.

[0003] The direct exhaust method of the existing technology introduces fresh air from the outside and directly discharges it out of the dryer after drying. On the one hand, the direct exhaust drying method consumes a lot of energy, especially when the outside temperature is low, which is not conducive to saving; on the other hand, the gas after drying is mostly high-temperature and high-humidity gas. Discharging the high-temperature and high-humidity gas after drying directly from the inner drum into the room will cause the humidity and temperature of the indoor air to be too high, and the indoor air with excessive temperature and humidity will then enter the inner drum through the fresh air duct, resulting in the air quality being unable to be guaranteed in the long term, which is easy to cause damage and pollution to the clothes during drying. Therefore, it is necessary to optimize the devices in the existing direct exhaust method to reduce odor or foreign matter, improve control quality, and achieve efficient drying.

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings. The above-mentioned and other purposes, features, aspects and advantages of the present invention will become more apparent so that those skilled in the art can implement them with reference to the text of the specification.

[0049] Next, the present invention will be further described in conjunction with 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 the terms "having," "including," and "comprising" used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0050] Example 1:

[0051] like Figures 1-9 As shown, the present invention further provides a heat exchange assembly 10 , including an air outlet module 12 and a box body, wherein the box body includes an upper shell 11 and a lower shell 13 .

[0052] 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 heat conducting materials.

[0053] 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.

[0054] 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, so that the cooling water in the water channel structure 121 does not mix with the gas to be cooled in the air channel structure, ensuring that the temperature of the cooling water can be reused.

[0055] The heat conducting plate 123 is provided with a drain port 1231, preferably located at the edge of the heat conducting plate 123. The air duct structure 122 further includes a partition 1222, which 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, partially surrounding the drain port 1231. This allows the drain port 1231 to directly communicate with the cooling medium outlet 133 on the box body. After circulating in the water channel, the cooling water entering the air outlet module 12 enters the cooling medium outlet 133 through the drain port 1231 without coming into contact with the gas in the air duct structure 122, ensuring that the temperature of the cooling water in the water duct structure 121 can be reused.

[0056] 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.

[0057] 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 is parallel to the third baffle 1243 .

[0058] The heat conducting plate 123 is provided with a mounting hole 1233 . After the air outlet module 12 is placed on the lower housing 13 , it is installed in the mounting hole 1233 by screws or bolts to achieve fixed installation of the heat conducting plate 123 and the lower housing 13 .

[0059] The first baffle 1241 is provided with a semicircular notch 12411 . After the upper shell 11 is installed on the lower shell 13 , the notch 12411 is located at the cooling medium inlet 111 .

[0060] The water channel structure 121 includes: a plurality of upper fins 1211, each of which is a rectangular sheet structure without any bends, and a water channel is formed between adjacent upper fins 1211. The plurality of upper fins 1211 are parallel to each other, and the spacing between adjacent upper fins 1211 is equal.

[0061] Preferably, the upper fin 1211 is located in a groove formed by the baffle 124 and the heat conducting plate 123 , that is, the water channel structure 121 is located in the groove.

[0062] 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 curved water channel.

[0063] See also Figure 5 and Figure 6 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. It can be understood that the first baffle 1241 or the third baffle 1243 is the connection end of the upper fin 1211, and the upper fin 1211 is perpendicular to the first baffle 1241 or the third baffle 1243, or inclined to the first baffle 1241 or the third baffle 1243. The upper fin 1211 is perpendicular to or inclined to the connection end of the upper fin 1211.

[0064] Preferably, this embodiment refers to Figure 6 The 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 relative to the first baffle 1241 or the third baffle 1243. The first baffle 1241 or the third baffle 1243 is the connection end of the upper fin 1211, and the upper fin 1211 is inclined relative to the connection end of the upper fin 1211. When 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 heat transfer of the cooling water and improves the efficiency of heat exchange.

[0065] The upper fins 1211 are designed to be parallel to each other and cross-connected to the first baffle 1241 and the third baffle 1243 opposite to each other, which can increase the area of ​​the water channel and increase the contact area between the cooling medium and the heat conducting plate 123. Figure 6 All parts of the heat conducting plate 123 are in contact with the cooling medium, and the sheet-like structure of the upper fin 1211 has a non-bending design, which reduces the manufacturing cost.

[0066] The air duct structure 122 includes: a plurality of lower fins 1221 and a 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.

[0067] 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.

[0068] The lower fin is fixed to the heat conducting plate 123 in the air outlet module 12, and the heat conducting plate 123 is provided with a drain port 1231. The partition 1222 is an extension of the heat conducting plate away from the air path structure and is located at the edge of the drain port, half surrounding the drain port 1231.

[0069] Preferably, in this embodiment, since the heat conducting plate 123 is substantially 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 water channel formed by the lower fins 1221 has the same width. 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 the curvature ranging from 10 degrees to 90 degrees.

[0070] Specifically, see 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, while the end portion 12212 contacts the lower housing 13 of the air outlet module 12. Preferably, the thickness of the root portion 12211 is greater than that of the end portion 12212, thereby ensuring structural strength while saving material.

[0071] Preferably, the inner arc of the lower fin 1221 faces the air inlet 132 of the air outlet module 12, so that the air entering the air duct from the air inlet 132 hits the lower fin 1221 and then enters each air duct, which increases the contact area of ​​the air and improves the cooling speed of the humid and hot air.

[0072] Preferably, in this embodiment, reference Figure 3 The number of the lower fins 1221 is 7, wherein the inner arc of the first lower fin faces the air inlet 132 of the air outlet module 12, and the air duct formed between the sixth lower fin and the seventh lower fin faces the air outlet 131.

[0073] The housing includes an upper shell 11 and a lower shell 13. The upper shell 11 is provided with a cooling medium inlet 111, and the lower shell 13 is provided with an air inlet 132, an air outlet 131, and a cooling medium outlet 133. A semicircular baffle is provided at the air outlet 131, giving it a semicircular shape. The baffle is located at the bottom of the air outlet 131 to prevent water from escaping.

[0074] The heat conducting plate 123 is made of heat conducting material, such as metal and alloy. The upper shell 11 and the lower shell 13 are made of plastic or metal.

[0075] The air inlet 132 is higher than the air outlet 131 and larger than the air outlet 131 to avoid airflow turbulence. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to allow for the timely discharge of condensed water. This prevents excessive condensed water from forming in the air outlet module 12, which would increase humidity in the air outlet module 12 and hinder dehumidification of the hot and humid air.

[0076] The lower shell 13 includes a side wall and a bottom. The bottom is an inclined bottom, and the cooling medium outlet 133 is located at the inclined bottom.

[0077] Preferably, the inclined bottom portion 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 either side 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 sidewall, 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 serve as transition surfaces between the second inclined surface 135 and the sidewall. A transition inclined surface 137 is also provided between the sidewall and the second inclined surface 135.

[0078] The cooling medium outlet 133 is located on the second inclined surface 135. The condensed water, guided by its own gravity, eventually falls to the bottom of the lower housing 13. The design of the first inclined surface 134, the second inclined surface 135, the third inclined surface 136, and the transition inclined surface 137 positions the cooling medium outlet 133 well below the cooling medium inlet 111, allowing for timely discharge of the cooling medium to prevent excessive condensation in the air outlet module 12. This also prevents condensation from accumulating at the bottom, which would increase humidity in the air outlet module 12 and hinder dehumidification of the hot and humid air.

[0079] 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 shell 13 is smoother, thereby reducing the noise of the cooling medium in the heat exchange assembly 10 .

[0080] The air inlet 132 and air outlet 131 are located on two adjacent side walls. The curved surface of the lower fin 1221 faces the air inlet 132, allowing air entering the air duct from the air inlet 132 to strike the lower fin 1221 before entering the air ducts. This increases the air contact area and improves the cooling rate of the hot and humid air. Due to the curved design of the lower fin 1221, the air outlet 131 is located on the side wall adjacent to the air inlet 132.

[0081] Both the upper housing 11 and the lower housing 13 have groove structures. When the upper housing 11 and the lower housing 13 are fixedly installed, they form a storage space for the air outlet module 12. 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 a secure fit after snap-fitting.

[0082] When the upper and lower housings 11 and 13 are fastened together, the cooling medium inlet 111 is located between the baffle 124 and the upper fins 1211. The air inlet 132 is higher than the air outlet 131. Cooling water enters the water channel structure 121 through the cooling medium inlet 111, passes through the upper fins 1211, and flows into the various water channels. The heat conduction of the heat conducting plate 123 cools the hot and humid air in the air channel structure 122. The cooling water then flows into the lower housing 13 through the drain port 1231 and is discharged through the cooling medium outlet 133 at the bottom of the lower housing 13. Simultaneously, the hot and humid air exhausted from the clothes drying device enters the air channel structure 122 through the air inlet 132, passes through the lower fins 1221, and flows into the various air channels. After being cooled to low-temperature and low-humidity air by the heat conducting plate 123, it is discharged through the air outlet 131.

[0083] In short, the cooling medium enters the water channel structure 121 through the cooling medium inlet, removes heat from the heat conducting plate 123, and flows out through the cooling medium outlet 133 at the bottom of the lower housing 13. The heat conducting plate 123 enables heat exchange between the cooling water in the water channel structure 121 and the hot and humid air in the air channel structure 122. The hot and humid air in the clothes drying drum enters the air channel structure 122 through the air inlet 132, is cooled and dehumidified by the heat conducting plate 123, and is converted into low-temperature and low-heat air and discharged through the air outlet 131.

[0084] The present invention provides a water-gas separation heat exchange component, in which the cooling water in the water path structure 121 circulates on the heat conducting plate 123, thereby cooling the high-temperature and high-humidity gas in the air path structure 122, and converting the high-temperature and high-humidity gas after the clothes are dried into low-temperature and low-humidity air, which is discharged to the outside of the clothes drying device. This can improve the efficiency of clothes drying, ensure the temperature and humidity of the outside air, ensure the quality of the air entering the drying drum through the fresh air duct, reduce odor, improve control quality, and achieve efficient drying.

[0085] The heat conducting plate 123 in the water-gas separation heat exchange component provided by the present invention separates the water channel structure 121 from the air channel structure 122. The cooling water in the water channel structure 121 is not mixed with the high-temperature and high-humidity gas discharged from the drying device, ensuring that the cooling water flows out at a faster speed, increasing the contact area of ​​the cooling water in the water channel structure, ensuring that the temperature of the cooling water is sufficient for secondary utilization, and the water-gas separation design improves the dehumidification effect on high-humidity and hot air.

[0086] The design of the water channel structure 121 in the water-gas separation heat exchange assembly provided by the present invention 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 gas channel length, thereby improving the cooling efficiency of the moist hot air.

[0087] In a water-gas separation heat exchange component provided by the present invention, the cooling medium outlet 133 is located at the bottom of the inclined lower shell 13. The bottom of the lower shell 13 includes multiple inclined surfaces to discharge the cooling medium in time, avoid condensed water accumulation at the bottom, and improve the dehumidification efficiency.

[0088] Example 2:

[0089] The present invention also provides a clothes drying device, see Figures 1-10 , box, constituting the basic external structure of the device; a drying drum 3 and an outer drum are arranged in the box, and the drying drum 3 is used to accommodate dried clothes; the drying drum 3 is connected to the exhaust duct to discharge the hot and humid air in the drying drum out of the box after treatment; the exhaust duct 2 is provided with a heat exchange component 10 as in Example 1; wherein, the hot and humid air in the drying drum enters the heat exchange component 10 and is converted into low-temperature and low-heat air for discharge.

[0090] The air outlet module 12, together with the upper and lower housings 11 and 13, forms a heat exchange assembly 10. The upper housing 11 is provided with a cooling medium inlet 111, while the lower housing 13 is provided with an air inlet 132, an air outlet 131, and a cooling medium outlet 133. The exhaust duct 2 connects to the air inlet 132, while the air outlet 131 is connected to the outside. In this embodiment, the heat exchange assembly 10 is similar to that of Embodiment 1 and is not detailed here.

[0091] Preferably, the clothes drying device includes a fresh air system, which includes an air inlet duct 1 and an exhaust duct 2. The air inlet duct 1 connects to a clothes drying drum 3, for drawing air outside the device into the drying drum 3. The exhaust duct 2 connects to the drying drum 3, and a heat exchange assembly 10 is disposed on the exhaust duct 2. The high-humidity and high-temperature air in the drying drum 3 is cooled by the heat exchange assembly 10 and then discharged outside the drum into the room.

[0092] Preferably, the clothes drying device also includes a condenser 4, which is connected to the outer drum. The hot and humid air in the drying drum 3 enters between the inner and outer drums through the holes on the drying drum 3, and enters the condenser 4 through the holes on the outer drum. The condenser 4 condenses the hot and humid air entering the condenser from the outer drum. The other end of the condenser is connected to the drying drum 3, so that the condensed air is heated by the heating component 51 in the circulating air duct 5 under the action of the fan volute 52 and then supplied to the drying drum 3.

[0093] Preferably, the cooling medium outlet 133 on the heat exchange assembly 10 is connected to the condenser 4. The cooling water enters the condenser 4 after passing through the water channel structure of the air outlet module 12 and is reused by the condenser 4. This improves water utilization. At the same time, the heat exchange assembly 10 directly discharges moisture, thereby increasing drying efficiency and shortening drying time.

[0094] The clothes drying device is a dryer or a washer-dryer.

[0095] The present invention provides a water-gas separation heat exchange component, which is installed on the exhaust duct of the drying device, and can prevent the problem of foam overflow caused by excessive washing powder; the cooling water in the water channel structure 121 circulates on the heat conducting plate 123 to cool the high-temperature and high-humidity gas in the air channel structure 122, and converts the high-temperature and high-humidity gas after the clothes are dried into low-temperature and low-humidity air and discharges it to the outside of the clothes drying device, which can improve the efficiency of clothes drying, and ensure the temperature and humidity of the outside air, ensure the quality of the air entering the drying drum through the fresh air duct, reduce odor, improve control quality, and achieve efficient drying.

[0096] The heat conducting plate 123 in the water-gas separation heat exchange component provided by the present invention separates the water channel structure 121 from the air channel structure 122. The cooling water in the water channel structure 121 is not mixed with the high-temperature and high-humidity gas discharged from the drying device, ensuring that the cooling water flows out at a faster speed, increasing the contact area of ​​the cooling water in the water channel structure, and ensuring that the temperature of the cooling water is high enough to be reused.

[0097] The design of the water channel structure 121 in the water-gas separation heat exchange assembly provided by the present invention 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 gas channel length, thereby improving the cooling efficiency of the moist hot air.

[0098] In a water-gas separation heat exchange component provided by the present invention, the cooling medium outlet 133 is located at the bottom of the inclined lower shell 13. The bottom of the lower shell 13 includes multiple inclined surfaces to discharge the cooling medium in time, avoid condensed water accumulation at the bottom, and improve the dehumidification efficiency.

[0099] In some embodiments, the clothing drying device is a drying machine or a washer-dryer. When it is a washer-dryer, it has a corresponding structure and function for washing clothes, and a drum-type washer-dryer is more preferred.

[0100] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to specific details.
