Description

Technical Field

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

[0002] Currently available clothes drying devices, such as dryers and washer-dryers, mainly adopt condensation cycle drying. The principle is generally to heat the air through a heater and enter 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 amount of condensation water. In addition, the circulation temperature is high, which causes damage to the clothes. Therefore, it is necessary to optimize the existing clothes drying device and adopt a direct discharge method.

[0003] The direct exhaust method of the prior art introduces fresh air from the outside and directly discharges it from 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 enter the inner drum through the fresh air duct, resulting in the air quality cannot be guaranteed for a long time, which is easy to cause damage and pollution to the drying of clothes. 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.

[0051] Next, the present invention is further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be understood that the terms such as "having", "including" and "comprising" used herein do not specify the existence or addition of one or more other elements or their combinations.

[0052] Embodiment 1:

[0053] like Figure 1-Figure 8 As shown, the present invention further provides a heat exchange component 10, which is located on the exhaust duct of the clothes drying device and is used to cool and dehumidify the humid hot water vapor in the exhaust duct.

[0054] The heat exchange assembly 10 includes an air outlet module 12 and a box body, and the box body includes an upper shell 11 and a lower shell 13 .

[0055] The air outlet module 12 includes a water channel structure 121 , a heat conducting plate 123 and an air channel structure 122 .

[0056] 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. A plurality of through holes 1232 are evenly arranged on the heat conducting plate 123, and the through holes 1232 connect the water channel structure 121 with the air channel structure 122, so that the water channel structure 121 and the air channel structure 122 are connected, so that the cooling water in the water channel structure 121 is mixed with the air to be cooled in the air channel structure 122.

[0057] The heat conducting plate 123 is provided with a drain port 1231, and preferably, the drain port 1231 is located at the edge of the heat conducting plate 123. The air path structure 122 further includes a partition 1222, which is extended from the heat conducting plate 123 in a direction away from the air path structure and is located at the edge of the drain port 1231, and half surrounds the drain port 1231, so that the drain port 1231 is directly connected to the cooling medium outlet 133 on the lower shell 13.

[0058] The size of the drain port 1231 is larger than the size of the through hole 1232. After the cooling water entering the air outlet module 12 circulates in the water channel, a large amount of cooling water enters the cooling medium outlet 133 through the drain port 1231 and is discharged, and a small amount of cooling water enters the air path structure 122 through the through hole 1232. The cooling water exchanges heat with the heat conducting plate 123 to cool the gas in the air path structure 122.

[0059] A baffle 124 is provided at the edge of the heat conducting plate 123. Preferably, the heat conducting plate 123 is bent toward the water channel structure 121 to form the 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.

[0060] 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 .

[0061] 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 .

[0062] The first baffle 1241 is provided with a semicircular notch 12411, and the upper shell 11 is installed after the lower shell 13, and the notch 12411 is located at the cooling medium inlet 111. That is, after the upper shell 11 is installed after the lower shell 13, the cooling medium inlet 111 overlaps with the notch 12411.

[0063] The water channel structure 121 includes: a plurality of upper fins 1211 parallel to each other, the upper fins 1211 are rectangular sheet structures without bends, and water channels are 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.

[0064] 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.

[0065] 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.

[0066] See also Figure 4 and Figure 5 The included angle between the upper fin 1211 and the first baffle 1241 or the third baffle 1243 is an acute angle. It can be understood that the upper fin 1211 is inclined to the first baffle 1241 and the third baffle 1243.

[0067] 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 to the first baffle 1241 or the third baffle 1243. Preferably, the upper fin 1211 is welded 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 to the connection end of the upper fin 1211.

[0068] 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 waterway from the cooling medium inlet 111, due to the angle between the upper fin 1211 and the first baffle 1241 and the third baffle 1243, the upper fin 1211 is inclined relative to the first baffle 1241 and the third baffle 1243, and the upper fin 1211 is inclined relative to the cooling medium inlet 111. The angle between the axis of the cooling medium inlet 111 and the plane of the upper fin is an acute angle. When the cooling medium enters the waterway structure through the cooling medium inlet 111, it will impact the upper fin 1211, so that the cooling medium flows into any angle on the heat conducting plate 123, thereby improving the heat exchange efficiency between the cooling medium and the heat conducting plate 123. The water flow impacting the upper fin 1211 makes the cooling medium flow into the remaining waterways, which is more conducive to the heat transfer of the cooling water and improves the efficiency of the heat exchange.

[0069] The upper fin 1211 is integrally formed or welded to the baffle 124 and the heat conducting plate 123. The upper fin 1211 is a rectangular sheet structure. One end of two adjacent upper fins 124 is integrally formed or fixedly connected to the first baffle 1241 and the third baffle 1243 to form a continuous water channel. The bottom end of the upper fin 124 is integrally formed or welded to the heat conducting plate 123, so that the entire heat conducting plate 123 is in contact with the cooling water.

[0070] 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 5 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.

[0071] The air passage structure 122 includes: a plurality of lower fins 1221 and a partition plate 1222 , at least two lower fins 1221 are arc-shaped lower fins, and an arc-shaped air passage is formed between adjacent arc-shaped lower fins.

[0072] 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.

[0073] The lower fin is fixed to the heat conducting plate 123 in the air outlet module 12, and a drain port 1231 is provided on the heat conducting plate 123. The partition plate 1222 is an extension of the heat conducting plate in a direction away from the air path structure and is located at the edge of the drain port, half surrounding the drain port 1231.

[0074] Preferably, in this embodiment, since the heat conducting plate 123 is substantially square, the size of each lower fin 1221 in the plurality of lower fins 1221 is different. Specifically, the spacing between the plurality of lower fins 1221 is equal, that is, the width of the water channel 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, and the curvature is 10 degrees to 90 degrees.

[0075] 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 contacts 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 materials while ensuring structural strength.

[0076] 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, thereby increasing the contact area of ​​the air and improving the cooling speed of the humid and hot air.

[0077] 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.

[0078] The box body 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. The air outlet 131 is provided with a semicircular baffle, so that the shape of the air outlet 131 is semicircular, and the baffle is located at the bottom of the air outlet 131 to prevent water from being discharged.

[0079] 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.

[0080] The air inlet 132 is higher than the air outlet 131, and the air inlet 132 is larger than the air outlet 131 to avoid air flow disturbance. The cooling medium outlet 133 is much lower than the cooling medium inlet 111 to discharge condensed water in time to avoid excessive condensed water content in the air outlet module 12, which will increase the humidity of the air outlet module 12 and be detrimental to the dehumidification of the humid hot air.

[0081] See also Figure 7 and Figure 8 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.

[0082] 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, and the upper ends of the first inclined surface 134 and the third inclined surface 136 are connected to the side wall, and the lower ends are connected to the second inclined surface 135. It can be understood that the first inclined surface 134 and the third inclined surface 136 are transition surfaces between the second inclined surface 135 and the side wall. A transition inclined surface 137 is also provided between the side wall and the second inclined surface 135.

[0083] The cooling medium outlet 133 is located on the second inclined surface 135. The condensed water will eventually fall to the bottom of the lower shell 13 due to the guiding effect of its own gravity. 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 that the cooling medium is discharged in time to avoid excessive condensed water content in the air outlet module 12, and at the same time increase the circulation rate of the cooling medium, which leads to an increase in the humidity of the air outlet module 12, which is not conducive to the dehumidification of the humid hot air.

[0084] 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 .

[0085] The air inlet 132 and the air outlet 131 are located on two adjacent side walls. The arc surface of the lower fin 1221 faces the air inlet 132, so that the air entering the air duct from the air inlet 132 hits the lower fin 1221 and then enters each air duct, increasing the contact area of ​​the air and improving the cooling speed of the humid and hot air. Due to the arc design of the lower fin 1221, the air outlet 131 is located on the side wall adjacent to the air inlet 132.

[0086] The upper shell 11 and the lower shell 13 are both groove structures. After the upper shell 11 and the lower shell 13 are fixedly installed, a storage space for accommodating the air outlet module 12 is formed. The upper shell 11 and the lower shell 13 can be snap-fitted. Preferably, the upper shell 11 can be screwed with the air outlet module 12 to achieve fixation after snap-fitting.

[0087] Specifically, the upper shell 11 is also provided with a mounting portion 112 for mounting the entire heat exchange assembly 10 inside the clothes drying device. The upper shell 11 is also provided with a fixing portion 113, and the fixing portion 113 is a threaded hole. Preferably, a mounting groove corresponding to the fixing portion 113 is provided on the baffle 124. The air outlet module 12 is fixedly mounted on the lower shell 13 by passing bolts or screws through the mounting holes 1233, and the baffle 124 protrudes from the lower shell 13, and then the upper shell 11 is buckled, and the upper shell 11 is screwed to the baffle 124 through the fixing portion 113.

[0088] After the upper shell 11 and the lower shell 13 are installed, the cooling medium inlet 111 is located between the baffle 124 and the upper fin 1211, the air inlet 132 is higher than the air outlet 131, and the cooling water enters the water channel structure 121 through the cooling medium inlet 111, flows into each water channel after being impacted by the upper fin 1211, and cools the hot and humid air in the air channel structure 122 through the heat conduction effect of the heat conductive plate 123, a large amount of cooling water flows into the lower shell 13 through the drain port 1231, and a small amount of cooling water flows into the lower shell 13 through the through hole 1232, 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 air inlet 132, flows into each air channel after being impacted by the lower fin 1221, and is cooled to low-temperature air by the heat conductive plate 123, and is discharged from the air outlet 131.

[0089] In short, the cooling medium enters the water channel structure 121 from the cooling medium inlet, takes away the heat of the heat conducting plate 123, and flows 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 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 from the air inlet 132, and becomes low-temperature and low-heat air after being cooled and dehumidified by the heat conducting plate 123 and is discharged from the air outlet 131.

[0090] A water-gas mixed heat exchange component provided by the present invention is installed on the exhaust air duct of the drying device, which can prevent the problem of foam overflow caused by too much washing powder; the cooling water in the water channel structure 121 cools the high-temperature and high-humidity gas in the air channel structure, 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.

[0091] The present invention provides a water-gas mixed heat exchange component, in which the water channel structure 121 and the air channel structure 122 are connected through the through hole 1232, and a small amount of cooling water directly flows into the air channel structure through the through hole 1232, thereby improving the cooling efficiency of the gas in the air channel structure 122.

[0092] The upper fin 1211 in the water channel structure 121 of the present invention is inclined so that the upper fin 1211 is inclined relative to the cooling medium inlet. When the cooling medium enters the water channel structure 121 through the cooling medium inlet 111, it will impact the upper fin 1211, thereby causing the cooling medium to flow into any angle on the heat conduction plate 123, thereby improving the heat exchange efficiency between the cooling medium and the heat conduction plate 123.

[0093] The upper fin 1211 of the water channel structure of the present invention increases the contact area between the cooling medium and the heat conducting plate 123, thereby improving the cooling efficiency. The arc-shaped lower fin 1221 of the air channel structure 122 increases the gas channel length, thereby improving the cooling efficiency of the humid hot air.

[0094] 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, and the bottom of the lower shell 13 includes multiple inclined surfaces to discharge the cooling medium in time, increase the circulation rate of the cooling medium, and improve the dehumidification efficiency.

[0099] 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.

[0100] Preferably, the cooling medium outlet 133 on the heat exchange component 10 is connected to the condenser 4, and 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.
