[0002] With the improvement of people's living standards, users' requirements for dryers are not only for cleaning. Due to weather factors, such as the rainy season, the drying time of clothes after washing is relatively long, and some users also need a dryer that can dry clothes.

[0003] At present, the dryers on the market form hot air through a heater, and the hot air is introduced into the drying drum by a blower. The hot air can take away the moisture on the surface or inside of the wet clothes, and thus achieve the drying of the wet clothes. The formed hot and humid air is discharged from the air outlet of the inner drum. If the hot and humid air discharged from the inner drum is directly discharged outside the dryer, it will have a greater impact on the humidity and temperature of the environment where the dryer is located. The present application proposes a moisture exhaust device for cooling and dehumidifying the hot and humid air generated by the drying drum and then discharging it outside the dryer, and further optimizes the layout of the drainage pipeline of the moisture exhaust device.

[0011] Preferably, the water inlet of the drainage pipeline is disposed on the bottom wall of the housing.

[0012] Preferably, the side of the water inlet close to the water outlet is arranged on the side wall of the housing.

[0013] Preferably, the side of the water inlet far from the water outlet is inclined downward toward the water outlet to form a first water guiding portion for guiding the water flow toward the water outlet.

[0016] Preferably, the water inlet is arranged on the connecting portion.

[0017] Preferably, the bottom wall of the housing is inclined downward from the side far from the water inlet toward the water inlet to guide the water flow on the bottom wall of the housing toward the water inlet.

[0018] Preferably, the side wall of the housing close to the drainage pipe is inclined toward the drainage pipe to form a third water guiding portion for guiding the water flow on the side wall toward the water inlet.

[0019] Preferably, the water inlet of the drainage pipe corresponds to the position of the cooling medium outlet of the heat exchange member of the moisture exhaust device body.

[0020] Preferably, an air inlet is provided on one side of the housing; the water inlet of the drainage pipe is close to the air inlet.

[0021] The second object of the present invention is to provide a moisture exhaust device, including a moisture exhaust device body arranged in the dryer body, the moisture exhaust device body includes a heat exchange member, and further includes a housing of the outer shell structure of the dryer moisture exhaust device as described above; the heat exchange member is arranged in the cavity; wherein,

[0022] The hot and humid air generated by the drying cylinder of the dryer body enters the cavity, contacts the heat exchange member for heat exchange, and the cooled and dehumidified air is discharged outside the dryer body through the air outlet.

[0023] Preferably, the heat exchange member is provided with a cooling portion; the cooling portion is provided with a cooling channel for accommodating a cooling medium.

[0024] Preferably, the cooling channel is located above the hot and humid air in the cavity.

[0025] The third object of the present invention is to provide a clothes dryer, including a clothes dryer body for performing drying, and the clothes dryer body includes a moisture exhaust device body of the moisture exhaust device as described above.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] For the housing structure of the moisture exhaust device of the clothes dryer provided by the present invention, the housing is provided with a drainage pipe for discharging the condensed water in the cavity, and the water outlet of the drainage pipe extends out of the side wall of the housing, so that the condensed water in the cavity can be discharged from the side of the housing. Since the size and position of the drying cylinder are determined, the moisture exhaust device body is usually installed in the space around the drying cylinder. The arrangement that the water outlet of the drainage pipe extends out of the side wall of the housing facilitates the connection between the drainage pipe of the moisture exhaust device body and the components located on the side of the moisture exhaust device body, simplifies the corresponding pipeline connection, and avoids the increase in the space occupied by the connecting pipeline in the clothes dryer body due to the bending of the connecting pipeline.

[0028] In a preferred solution, the water inlet of the drainage pipe is arranged on the bottom wall of the housing to timely discharge the condensed water formed during the cooling of the hot and humid air.

[0029] In a preferred solution, the bottom wall of the drainage pipe is respectively inclined downward from two opposite edges towards the water inlet to form a second drainage part, guiding the condensed water to flow to the water inlet, so as to prevent the condensed water from accumulating on the bottom wall of the housing and increasing the humidity in the cavity, which is not conducive to the cooling and dehumidification treatment of the hot and humid air by the heat exchange element.

[0030] For the moisture exhaust device for a clothes dryer provided by the present invention, after the hot and humid air generated by the drying cylinder is cooled and dehumidified, the air after the cooling and dehumidification treatment is discharged to the outside of the clothes dryer body through the air outlet, reducing the influence of the air discharged during the drying process of the clothes dryer body on the temperature and humidity of the environment where the clothes dryer body is located, and avoiding environmental pollution; the water outlet of the drainage pipe extends out of the side wall of the housing, facilitating the connection between the drainage pipe of the device and the pipeline of the clothes dryer body after the moisture exhaust device body is installed in the space around the drying cylinder. Further, the drainage pipe is connected to the condenser in the clothes dryer body. The drainage pipe and the condenser are respectively arranged on both sides of the drying cylinder, and the water outlet of the drainage pipe faces the condenser, so as to facilitate the connection between the drainage pipe and the condenser and save the internal space of the clothes dryer body occupied by the pipeline connection.

[0031] In a preferred embodiment, the cooling part is provided with a cooling medium outlet, which is respectively communicated with a cooling channel and a cavity. The cooling medium that has absorbed heat in the cooling channel is discharged from the cooling medium outlet into the cavity and then discharged together with the condensed water through a drainage pipe, reducing the number of pipe outlets provided on the housing, and thus simplifying the pipe layout structure when the moisture exhaust device body is installed in the dryer body. Further, a stop portion is provided on the back of the cooling medium outlet to prevent the cooling medium from contacting the humid and hot air during the process of flowing out of the cooling medium outlet, so as to reduce the contact area between the cooling medium whose temperature has risen due to absorbing the heat of the humid and hot air and the humid and hot air, so as not to be unfavorable to the cooling of the humid and hot air.

[0032] In a preferred embodiment, since the temperature of the cooling medium in the cooling channel gradually rises during the flowing process, by limiting that the apertures of a plurality of holes gradually decrease along the flowing direction of the cooling medium in the cooling channel, the influence of the temperature difference of the cooling medium flowing out of the holes at different parts of the cooling channel on the cooling effect of the humid and hot air in the cavity can be reduced.

[0033] In a preferred embodiment, the cooling part of the moisture exhaust device body and the inner contour of the cavity together form a cooling channel through a plurality of partition plates, increasing the space of the cooling channel to improve the heat exchange effect between the cooling part and the humid and hot air, and at the same time reducing the space occupied by the cooling channel in the cooling part, which is beneficial to the miniaturized design of the cooling part.

[0034] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly and implement it according to the content of the description, the following takes the preferred embodiments of the present invention and coordinates with the attached drawings to elaborate in detail as follows.

[0050] Embodiment 1

[0051] The present invention provides a housing structure of a moisture exhaust device for a dryer, including an outer surface housing 10 for forming a moisture exhaust device body 1 disposed inside the dryer body; as Figures 1 to 5 shown, the housing 10 includes:

[0052] A cavity 11 for accommodating a heat exchange member 20; the cavity 11 is also used to form a temporary storage space for the humid and hot air. After the humid and hot air enters the cavity 11, due to the restraint of the cavity 11 contour, the flow rate of the humid and hot air is reduced, so that the humid and hot air temporarily accumulates in the cavity 11 to contact the heat exchange member 20 in the cavity 11;

[0053] An air inlet 12 for introducing the humid and hot air generated by the drying drum of the dryer body into the cavity 11;

[0054] An air outlet 13 for discharging the air after the humid and hot air is cooled and dehumidified by the heat exchange member 20 to the outside of the dryer body; the humid and hot air in the drying drum of the dryer body enters the cavity 11, the heat exchange member 20 absorbs the heat of the humid and hot air, and the humid and hot air condenses to form condensed water during the cooling process for dehumidification. The air after cooling and dehumidification is discharged to the outside of the dryer body through the air outlet 13, reducing the influence of the air discharged during the drying process of the dryer body on the temperature and humidity of the environment where the dryer body is located and avoiding environmental pollution;

[0055] A drainage pipe 15; the water outlet 151 of the drainage pipe 15 extends out of the side wall of the housing 10 to discharge the condensed water formed during the cooling process of the humid and hot air in the cavity 11 from the side of the housing 10. The water outlet 151 of the drainage pipe 15 extends out of the side wall of the housing 10, that is, the water outlet 151 faces the side of the housing 10 to discharge the condensed water formed during the cooling process of the humid and hot air in the cavity 11 from the side of the housing 10. The moisture exhaust device body 1 is disposed inside the dryer body. Usually, the drying drum occupies a relatively large space inside the dryer body. The moisture exhaust device body 1 is disposed in the space of the dryer body on the outer peripheral side of the drying drum. By setting the water outlet 151 to face the side of the housing 10, it is convenient for the connection between the drainage pipe 15 of the moisture exhaust device body 1 and the pipes of the components located on the side of the moisture exhaust device body 1 inside the dryer body. Specifically, the air inlet 12 of the housing 10 is communicated with the drying drum, and the air outlet 13 is communicated with the external environment of the dryer body.

[0056] In one embodiment, as Figures 2 to 5As shown, the water inlet 152 of the drainage pipe 15 is arranged on the bottom wall of the housing 10. The condensed water formed during the cooling process of the humid and hot air in the cavity 11 drops downward under its own gravity onto the bottom wall of the housing 10, and can then enter the drainage pipe 15 from the water inlet 152 arranged on the bottom wall of the housing 10 and be discharged outside the moisture exhaust device body 1. This can timely drain the condensed water formed in the cavity 11, so as to prevent excessive accumulation of condensed water in the cavity 11, which may affect the humidity inside the cavity 11 and further affect the cooling effect of the cooling part 21.

[0057] Furthermore, as Figure 2 , Figure 3 shown, the side of the water inlet 152 close to the water outlet 151 is arranged on the side wall of the housing 10, so as to facilitate the water flow in the cavity 11 to flow from the water inlet 152 of the drainage pipe 15 towards the water outlet 151. The drainage pipe 15 further includes a connecting part 153, and both ends of the connecting part 153 are respectively communicated with the water inlet 151 and the water outlet 152. The side of the water inlet 152 close to the water outlet 151 is arranged on the side wall of the housing 10, so as to facilitate the connection of the connecting part 153 with the water inlet 152. The side end of the connecting part 153 close to the water inlet 152 is partially connected to the side wall of the housing 10 and partially connected to the bottom wall of the housing 10, so as to prevent the drainage pipe 15 from protruding too much from the bottom wall of the housing 10 and increasing the overall size of the moisture exhaust device body 1.

[0058] Furthermore, as Figure 2 , Figure 3 shown, the side of the water inlet 152 close to the water outlet 151 extends upward and forms a notch 1521 on the side wall of the housing 10 to expand the water inlet 152. Part of the condensed water in the cavity 11 flows into the drainage pipe 15 from the opening of the water inlet 152 on the bottom wall of the housing 10, and part flows into the drainage pipe 15 from the notch 1521, so as to improve the drainage speed of the water inlet 152.

[0059] In one embodiment, as Figure 3 shown, the side of the water inlet 152 far from the water outlet 151 is inclined downward towards the water outlet 151 to form a first drainage part 1522, so as to guide the water flow towards the water outlet 151. After the condensed water in the cavity 11 flows into the water inlet 152, it flows along the first drainage part 1522. The slope structure of the first drainage part 1522 can accelerate the water flow on the surface of the first drainage part 1522 towards the water outlet 151 to a certain extent.

[0060] In one embodiment, as Figure 2 , Figure 4As shown, on two opposite sides of the bottom wall of the housing 10, downward inclinations are respectively formed towards the water inlet 152 to form a second water diversion portion 181, so as to guide the water flow on the bottom wall of the housing 10 towards the water inlet 152. The humid and hot air in the cavity 11 is cooled to form condensed water, which drops onto the second water diversion portion 181 and can flow along the inclined surface of the second water diversion portion 181 at an accelerated speed, accelerating the condensed water to flow to the water inlet 152 of the drainage pipe 15, preventing the condensed water from accumulating on the bottom wall of the housing 10, increasing the humidity of the environment in the cavity 11, and being disadvantageous to the cooling and dehumidification treatment of the humid and hot air by the cooling portion 21 of the heat exchange member 20.

[0061] Further, a connection portion 182 is provided on the bottom wall of the housing 10, and a second water diversion portion 181 is connected to each of the two sides of the connection portion 182. The condensed water on the surface of the second water diversion portion 181 flows along its surface, flows to the surface of the connection portion 182, and then flows along the surface of the connection portion 182 to the water inlet 152 of the drainage pipe 15. By providing the connection portion 182, it is avoided that the included angle between the two second water diversion portions 181 is too sharp and difficult to process; and while making the bottom contour of the housing 10 distinct, the streamline on the outer surface is soft, and no abrupt sharp corners will appear to affect the touch.

[0062] Further, as Figure 2 、 Figure 4 shown, the water inlet 152 is provided on the connection portion 182. Since the second water diversion portion 181 inclines downward towards the water inlet 152 and the position of the connection portion 182 is lower than that of the second water diversion portion 181, setting the water inlet 152 on the connection portion 182 facilitates the water flow on the bottom wall of the housing 10 to flow towards the water inlet 152 and accelerates the discharge of the accumulated water in the cavity 11.

[0063] In one embodiment, the bottom wall of the housing 10 inclines downward from the side far away from the water inlet 152 towards the water inlet 152 to guide the water flow on the bottom wall of the housing 10 towards the water inlet 152, facilitating the water flow on the bottom wall of the housing 10 to flow towards the water inlet 152 and accelerating the discharge of the accumulated water in the cavity 11.

[0064] In one embodiment, as Figure 4 shown, one side wall of the housing 10 close to the drainage pipe 15 inclines towards the drainage pipe 15 to form a third water diversion portion 19 to guide the water flow on this side wall towards the water inlet 152. Further, the side of the water inlet 152 close to the water outlet 151 is provided on the side wall of the housing 10 provided with the third water diversion portion 19, and the water flow in contact with the surface of the third water diversion portion 19 can flow downward along the inclined surface of the third water diversion portion 19 at an accelerated speed until it flows to the water inlet 152.

[0065] In one embodiment, a cooling channel 212 for accommodating a cooling medium is provided in the cooling part 21 of the heat exchange member 20. The cooling medium outlet 213 of the cooling part 21 is arranged in the cooling channel 212 and communicated with the cavity 11 of the housing 10, so as to discharge the cooling medium that has absorbed the heat of the humid and hot air into the cavity 11 and then discharge it from the drainage pipe 15. As Figure 2 , Figure 5 shown, the position of the cooling medium outlet 213 corresponds to the water inlet 152 of the drainage pipe 15. The drainage pipe 15 of the housing 10 is located on the bottom wall of the housing 10. The cooling medium outlet 213 corresponds to the drainage pipe 15. After the cooling medium that has absorbed the heat of the humid and hot air is discharged from the cooling medium outlet 213, under its own gravity, it can reach the drainage pipe 15 as soon as possible and be discharged, so as to prevent the cooling medium from accumulating in the cavity 11 due to untimely discharge, affecting the humidity of the cavity 11 and being unfavorable for the dehumidification of the humid and hot air.

[0066] In one embodiment, as Figure 5 shown, the air inlet 12 is arranged on one side of the housing 10. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12, contacts the heat exchange member 20 and is cooled, and the formed condensed water falls to the bottom wall of the housing 10 and is then discharged from the drainage pipe 15. In one embodiment, the cooling channel 212 is located above the humid and hot air, and the condensed water formed by the humid and hot air can directly fall to the bottom wall of the housing 10. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12 and approaches the heat exchange member 20 from the side of the heat exchange member 20, so as to prevent the humid and hot air from contacting the top wall of the heat exchange member 20 and accumulating on the top wall of the heat exchange member 20, which is not conducive to the discharge of the condensed water. Further, the water inlet 152 of the drainage pipe 15 is close to the air inlet 12, that is, the water inlet 152 of the drainage pipe 15 is close to the side of the housing 10 where the air inlet 12 is provided. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12. At this time, the humidity of the humid and hot air is relatively high, that is, the humidity and temperature of the air near the air inlet 12 in the cavity 11 are the highest. In addition, when the condensed water formed during the cooling process of the cooling medium and the humid and hot air flows towards the drainage pipe 15, it affects the humidity in a certain space around the drainage pipe 15 to a certain extent. The temperature and humidity of the humid and hot air at the air inlet 12 are not greatly affected by the temperature and humidity in a certain space around the drainage pipe 15. And even if the temperature and humidity of the humid and hot air at the air inlet 12 are affected and increased, the humid and hot air at the air inlet 12 exchanges heat with the cooling medium during the process of flowing towards the air outlet 13 of the housing 10 to cool and dehumidify, so as to ensure that the temperature and humidity of the air discharged from the air outlet 13 meet the specified requirements. Further, in one embodiment, the position of the cooling medium outlet 213 corresponds to the water inlet 152 of the drainage pipe 15, and thus the cooling medium outlet 213 is close to the air inlet 12. Because the humidity and temperature of the air near the air inlet 12 in the cavity 11 are the highest, the temperature and humidity of the humid and hot air at the air inlet 12 are not greatly affected by the cooling medium discharged from the cooling medium outlet 213.

[0067] Example 2

[0068] The present invention provides a moisture exhaust device, as Figure 1 , Figure 3 , Figure 4 , Figure 5 shown, which includes a moisture exhaust device body 1 disposed inside the dryer body. The moisture exhaust device body 1 includes:

[0069] The housing 10 as described above; the housing 10 is provided with a cavity 11 for accommodating the heat exchange member 20, an air outlet 13, and a drainage pipe 15; the heat exchange member 20 is disposed in the cavity 11 of the housing 10;

[0070] The heat exchange member 20 is used to cool the humid and hot air in the cavity 11; the heat exchange member 20 is disposed in the cavity 11; the humid and hot air in the drying cylinder of the dryer body enters the cavity 11, the heat exchange member 20 absorbs the heat of the humid and hot air, and the humid and hot air condenses to form condensed water during the cooling process for dehumidification. The air after cooling and dehumidification is discharged to the outside of the dryer body through the air outlet 13, reducing the influence of the air discharged during the drying process of the dryer body on the temperature and humidity of the environment where the dryer body is located, and avoiding environmental pollution;

[0071] The humid and hot air generated by the drying cylinder of the dryer body enters the cavity 11, contacts the heat exchange member for heat exchange, and the air after cooling and dehumidification is discharged to the outside of the dryer body through the air outlet 13. Specifically, the air inlet 12 of the housing 10 is communicated with the drying cylinder, and the air outlet 13 of the housing 10 is communicated with the external environment of the dryer body. After the dryer body starts the drying program, the heater of the dryer body heats the air entering the drying cylinder. The heated air causes the moisture contained in the clothes placed in the drying cylinder to evaporate and form an air flow containing water molecules. Under the guidance of the fan of the dryer body, the air flow containing water molecules is mixed into the hot air in the drying cylinder to form humid and hot air with relatively high temperature and humidity. The humid and hot air generated by the drying cylinder enters the cavity 11 through the air inlet 12, contacts the heat exchange member 20 located in the cavity 11 and is cooled. During the cooling process, the humid and hot air forms condensed water for dehumidification, and the air after cooling and dehumidification is discharged into the external environment of the dryer body, reducing the influence on the temperature and humidity of the environment where the dryer body is located and avoiding environmental pollution; and the humid and hot air in the drying cylinder is discharged in time, accelerating the drying program of the dryer body. Further, by limiting the heat absorption performance of the heat exchange member 20, the temperature and humidity of the air discharged to the external environment of the dryer body after being processed by the moisture exhaust device body 1 can be controlled. For example, the temperature of the air discharged from the dryer body can be controlled to be slightly lower than the room temperature, and the humidity is the humidity standard for a comfortable life. When it is a hot season, the temperature of the surrounding environment of the dryer body can also be appropriately adjusted to improve the user experience.

[0072] In one embodiment, asFigure 2 , Figure 5 As shown in Figure 5 , the heat exchanger 20 is provided with a cooling portion 21; the cooling portion 21 is provided with a cooling channel 212 for accommodating a cooling medium. Specifically, the cooling medium is located in the cooling channel 212. When the humid and hot air in the cavity 11 contacts the cooling portion 21, the heat of the humid and hot air is transferred to the outer wall of the cooling portion 21, and the cooling medium in the cooling channel 212 absorbs the heat on the outer wall of the cooling portion 21, thereby finally transferring the heat of the humid and hot air to the cooling medium to cool the humid and hot air in the cavity 11.

[0073] In one embodiment, as Figure 2 , Figure 5 shown, the cooling channel 212 is located above the humid and hot air in the cavity 11. The condensed water formed during the cooling of the humid and hot air falls under its own gravity and does not contact the outer wall of the cooling portion 21, so as to prevent the condensed water from accumulating on the outer wall of the cooling portion 21 and affecting its absorption of the heat of the humid and hot air. Further, the heat exchanger 20 includes an air channel 22 for accommodating the humid and hot air, and the cooling portion 21 is located above the air channel 22.

[0074] In one embodiment, as Figure 2 , Figure 5 , Figure 7 shown, the heat exchanger 20 further includes a plurality of air channels 22 for accommodating the humid and hot air. The humid and hot air generated by the drying drum enters the cavity 11 from the air inlet 12 and then enters the air channels 22 to extend the time for the humid and hot air to pass through the cavity 11. The air channels 22 are used to guide the flow of the humid and hot air, facilitating the humid and hot air entering the air channels 22 to contact the cooling portion 21 for cooling. Further, the air channels 22 are formed by a plurality of fins 23 or a plurality of thimbles. The fins 23 have a certain thermal conductivity and function to assist the heat dissipation of the humid and hot air in the air channels 22. When the cooling portion 21 is located above or on the side of the air channels 22, the lower openings of the air channels 22 formed by a plurality of fins 23 or a plurality of thimbles are beneficial to the discharge of the condensed water formed during the cooling of the humid and hot air in the air channels 22. The condensed water falls from the lower openings of the air channels 22 to the inner wall of the housing 10 and then is discharged from the drainage pipe 15 corresponding to the position on the housing 10 outside the moisture discharge device body 1. Preferably, the cooling portion 21 is located above the air channels 22.

[0075] In one embodiment, as Figure 5 shown, the space occupied by the cooling portion 21 in the cavity 11 is one-third to one-half of the space occupied by the air channels 22 in the cavity 11, so as to increase the height of the air channels 22, increase the amount of humid and hot air accommodated in the air channels 22, and enable the humid and hot air to be dispersed in the air channels 22, preventing the space of the air channels 22 from being too small, which may cause the humid and hot air to gather in the air channels 22 and is not conducive to the heat transfer of the humid and hot air.

[0076] In one embodiment, as Figure 2 、 Figures 5 to 9 shown, the cooling part 21 is provided with a cooling medium outlet 213; the cooling medium outlet 213 is respectively communicated with the cooling channel 212 and the cavity 11. The cooling medium outlet 213 is arranged on the cooling part 21 rather than on the housing 10, so as to reduce the number of pipes connected to the housing 10 and simplify the pipe layout structure when the dehumidifying device body 1 is installed in the dryer body.

[0077] Specifically, in one embodiment, the outer wall of the cooling channel 212 in contact with the humid and hot air in the cavity 11 is a heat conduction fin structure, so as to ensure the heat exchange effect between the cooling medium in the cooling channel 212 and the humid and hot air. In another embodiment, the heat exchange member 20 is a heat conduction structure, so as to improve the heat exchange effect with the humid and hot air in the cavity 11.

[0078] In one embodiment, in order to save costs and simplify the internal structure layout of the dryer body, the cooling medium is cooling water. The cooling water is cheap and easy to obtain. The cooling water can be provided to the dehumidifying device body 1 in time through the water circuit in the dryer body without replacing the cooling medium, and the operation is convenient.

[0079] In one embodiment, as Figure 2 、 Figure 5 shown, the position of the cooling medium outlet 213 corresponds to the water inlet 152 of the drain pipe 15. The drain pipe 15 of the housing 10 is located on the bottom wall of the housing 10. The cooling medium outlet 213 corresponds to the position of the drain pipe 15. After the cooling medium that has absorbed the heat of the humid and hot air is discharged from the cooling medium outlet 213, under its own gravity, it can reach the drain pipe 15 as soon as possible and be discharged, so as to prevent the cooling medium from accumulating in the cavity 11 due to untimely discharge in the cavity 11, affecting the humidity of the cavity 11 and being unfavorable for the dehumidification of the humid and hot air.

[0080] In one embodiment, as Figure 5As shown in the figure, the air inlet 12 is arranged on one side of the housing 10. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12, contacts the heat exchange member 20 and is cooled. The formed condensed water falls onto the bottom wall of the housing 10 and is discharged from the drain pipe 15. In one embodiment, the cooling channel 212 is located above the humid and hot air, and the condensed water formed by the humid and hot air can directly fall onto the bottom wall of the housing 10. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12 and approaches the heat exchange member 20 from the side of the heat exchange member 20, so as to prevent the humid and hot air from contacting the top wall of the heat exchange member 20 and accumulating on the top wall of the heat exchange member 20, which is not conducive to the discharge of condensed water. Further, the water inlet 152 of the drain pipe 15 is close to the side of the housing 10 where the air inlet 12 is provided. The humid and hot air generated by the dryer drum enters the cavity 11 from the air inlet 12. At this time, the humidity of the humid and hot air is relatively high, that is, the humidity and temperature of the air near the air inlet 12 in the cavity 11 are the highest. In addition, when the cooling medium and the condensed water formed during the cooling process of the humid and hot air flow towards the drain pipe 15, it will affect the humidity in a certain space around the drain pipe 15 to a certain extent. The temperature and humidity of the humid and hot air at the air inlet 12 are not greatly affected by the temperature and humidity in a certain space around the drain pipe 15. And even if the temperature and humidity of the humid and hot air at the air inlet 12 are affected and increased, during the process of flowing towards the air outlet 13 of the housing 10, the humid and hot air at the air inlet 12 exchanges heat with the cooling medium to cool down and dehumidify, so as to ensure that the temperature and humidity of the air discharged from the air outlet 13 meet the specified requirements. Further, in one embodiment, the cooling medium outlet 213 corresponds to the water inlet 152 of the drain pipe 15, and thus the cooling medium outlet 213 is close to the air inlet 12. Since the humidity and temperature of the air near the air inlet 12 in the cavity 11 are the highest, the temperature and humidity of the humid and hot air at the air inlet 12 are not greatly affected by the cooling medium discharged from the cooling medium outlet 213.

[0081] In one embodiment, the cooling medium outlet 213 provided in the cooling part 21 is arranged on the bottom wall of the cavity. Under its own gravity, the cooling medium can directly fall onto the inner bottom wall of the cavity 11 after flowing out from the cooling medium outlet 213, so as to reduce the probability of the cooling medium contacting the peripheral contour of the cavity 11, and prevent the cooling medium from accumulating on the surface of the peripheral contour of the cavity 11, which may cause an increase in the humidity in the cavity 11 and is not conducive to the dehumidification of the humid and hot air.

[0082] In one embodiment, as Figure 2As shown, there is a spacing between the cooling medium outlet 213 and the end of the cooling channel 212. When the cooling medium flows in the cooling channel 212 towards the cooling medium outlet 213, part of the cooling medium flows from the cooling medium outlet 213 into the cavity 11 and then flows to the drain pipe 15, and part of the cooling medium continues to flow towards the end of the cooling channel 212 to achieve a certain diversion effect, so as to avoid the cooling medium flowing to the end of the cooling channel 212 not being discharged from the cooling medium outlet 213 in time when the cooling medium outlet 213 is arranged at the end of the cooling channel 212, resulting in turbulence and generating noise.

[0083] In one embodiment, as Figure 5 、 Figure 7 shown, a stop portion 2131 is provided on the back of the cooling medium outlet 213 to prevent the cooling medium in the cooling channel 212 from contacting the humid and hot air during the process of flowing out of the cooling medium outlet 213. Since the temperature of the cooling medium increases after absorbing the heat of the humid and hot air, by providing the stop portion 2131 to block the contact area between the cooling medium discharged from the cooling medium outlet 213 into the cavity 11 and the humid and hot air, it is avoided that the cooling medium after absorbing heat is not conducive to the cooling of the humid and hot air. In one embodiment, the heat exchange member 20 includes a plurality of air channels 22 for accommodating the humid and hot air. By providing the stop portion 2131 to block the cooling medium flowing out of the cooling medium outlet 213 from entering the air channels 22, that is, to prevent the cooling medium that has absorbed the heat of the humid and hot air from flowing into the air channels 22 when discharging from the cooling channel 212, so as to reduce the contact area between the cooling medium whose temperature has risen due to absorbing the heat of the humid and hot air and the humid and hot air, and avoid that the cooling medium after absorbing heat is not conducive to the cooling of the humid and hot air. Further, the stop portion 2131 is bent, and together with the inner walls on both sides of the cavity 11, it forms a surrounding wall structure that surrounds the cooling medium flowing out of the cooling medium outlet 213. This surrounding wall structure can be completely enclosed or partially enclosed on the periphery, guiding the cooling medium to flow towards the drain pipe 15 while separating the air channels 22 from the cooling medium flowing out of the cooling medium outlet 213.

[0084] Further, the height of the stop portion 2131 is greater than the height of the side wall of the air channel 22 to further ensure that the cooling medium flowing out of the cooling medium outlet 213 does not enter the air channels 22.

[0085] Further, the stop portion 2131 is a heat conducting sheet, and the cooling medium discharged from the cooling medium outlet 213 flows down along the inner wall of the stop portion 2131. The humid and hot air in the cavity 11 contacts the outer wall of the stop portion 2131. Through the heat transfer function of the stop portion 2131 with a heat conducting sheet structure, the cooling medium discharged from the cooling medium inlet 14 absorbs part of the heat of the humid and hot air contacting the outer wall of the stop portion 2131, so as to make full use of the cooling medium and accelerate the cooling speed of the humid and hot air in the cavity 11.

[0086] Furthermore, the stop portion 2131 provided on the back of the cooling medium outlet 213 is offset from the position of the air inlet 12 to prevent the humid and hot air introduced from the air inlet 12 from contacting the cooling medium flowing out from the cooling medium outlet 213. Specifically, the air inlet 12 is provided on one side of the housing 10 close to the drainage pipe 15, and the cooling medium outlet 213 corresponds to the position of the drainage pipe 15. During the process of the humid and hot air introduced from the air inlet 12 flowing into the air channel 22 of the heat exchanger 20, by staggering the position of the stop portion 2131 from the air inlet 12, the contact area between the humid and hot air introduced from the air inlet 12 and the cooling medium discharged from the cooling medium outlet 213 is reduced, and the influence of the cooling medium discharged from the cooling medium outlet 213 on the humidity of the humid and hot air introduced from the air inlet 12 is reduced. If a small amount of humid and hot air contacts the cooling medium, the amount of this part of the humid and hot air is small, and thus it can be dehumidified by heat exchange with the cooling medium in the cooling portion 21 when passing through the air channel 22 subsequently.

[0087] In one embodiment, as Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9 shown, the cooling channel 212 of the heat exchanger 20 includes a cavity and a plurality of partition plates 211; the plurality of partition plates are arranged in sequence in the cavity, and the plurality of partition plates 211 and the inner contour of the cavity together form the cooling channel 212. Instead of the traditional scheme of using a curved pipe structure as the cooling channel, the space occupied by the distance between adjacent two pipe segments caused by the bending of the traditional pipe structure is reduced, that is, the space size of the cooling channel 212 corresponding to the same cavity space is increased, the amount of the cooling medium accommodated in the cooling portion 21 is increased, and the heat exchange is accelerated.

[0088] In one embodiment, as Figure 8 shown, the plurality of partition plates 211 are inclined, which increases the length of the partition plates 211 that can be accommodated in the internal cavity of the same cavity, and further increases the contact area between the inclined partition plates 211 and the cooling medium accommodated in the cooling channel 212, improves the heat exchange efficiency between the partition plates 211 and the cooling medium, and accelerates the absorption of the heat of the humid and hot air by the cooling medium. Further, by limiting the angle between the partition plates 211 and the inner side wall corresponding to the position of the cavity, the length of the partition plates 211 that can be accommodated in the cavity is ensured. In another embodiment, the plurality of partition plates 211 are all perpendicular to one side contour of the cavity to increase the number of the partition plates 211 that can be accommodated in the cavity.

[0089] In one embodiment, as Figure 2 , Figure 5 , Figure 6 , Figure 8 , Figure 9As shown, a number of partition plates 211 are arranged in parallel. The cross-sectional contour sizes in the same direction of each part of the channels formed by two adjacent partition plates 211 for accommodating the cooling medium are the same, so that the cooling medium flows smoothly in the channels formed by two adjacent partition plates 211, and it is not easy to cause turbulence due to the change of the internal size of the cooling channels, resulting in the generation of noise.

[0090] Furthermore, a number of partition plates 211 are arranged at equal intervals along the flowing direction of the humid and hot air. That is, the cross-sectional contour sizes in the same direction of the channels formed between any two adjacent partition plates 211 are the same, so that when the cooling medium flows in the cooling channels 212, the flow velocity remains the same or differs little when passing through the bend and entering the channels formed by the next two adjacent partition plates 211, so as to reduce the noise caused by the unstable flow of the cooling medium.

[0091] Furthermore, the partition plates 211 are heat-conducting sheets to improve the cooling effect of the cooling part 21. Specifically, after the humid and hot air in the cavity 11 transfers heat to the outer wall of the cooling part 21, part of the heat on the outer wall of the cooling part 21 is directly transferred to the cooling medium in the cooling channels 212, and part is first transferred to the partition plates 211 and then transferred to the cooling medium through the partition plates 211, accelerating the dissipation of the heat of the humid and hot air absorbed by the cooling part 21, and further accelerating the absorption of the heat of the humid and hot air in the cavity 11 by the outer wall of the cooling part 21. In addition, the partition plates 211 are inclined in the cavity of the cooling part 21, which increases the length of the partition plates 211 to a certain extent, and then increases the contact area between the partition plates 211 and the cooling medium, improves the heat exchange efficiency between the cooling medium and the partition plates 211, and accelerates the absorption of the heat of the humid and hot air by the cooling medium.

[0092] In an embodiment, two adjacent partition plates 211 are respectively connected in a staggered manner to the two inner walls with opposite positions in the cavity. Furthermore, the cooling medium inlet end (corresponding to the cooling medium inlet 14 of the housing 10) and the cooling medium outlet of the cooling channels 212 are respectively located outside the two outermost partition plates 211, so as to make full use of the space of the cavity, so that the space of the cavity is used to accommodate the cooling medium and a number of partition plates 211, increasing the amount of the cooling medium accommodated in the cavity.

[0093] In one embodiment, the ends of two adjacent partitions 211 intersect in a direction perpendicular to the partitions 211 to form a curved cooling channel 212, thereby forming a curved flow path, so that the cooling medium flows stably and the residence time of the cooling medium in the cooling channel 212 is ensured. The cooling medium entering the cavity first flows into the first channel connected to the cooling medium inlet end of the cooling channel 212, then flows into the second channel adjacent to the first channel, and then flows into the third channel adjacent to the second channel, and so on. A number of partitions 211 are reasonably arranged to make the cooling medium flow stably. The two adjacent channels formed by a number of partitions 211 are in a "U" shape, further improving the stability of the cooling medium flow. Further, the vertical distance between two adjacent partitions 211 is equal to the distance between one end of the partition 211 and the inner wall of the housing 10, so as to reduce the influence on the flow velocity of the cooling medium when the cooling medium flows to the bend in the cooling channel 212, so as to avoid causing turbulence.

[0094] In one embodiment, as Figure 2 shown, the plane where the partition 211 is located intersects the plane where the air channel 22 is located. Specifically, the number of air channels 22 is several. The plane where the partition 211 is located intersects the plane where the air channel 22 is located, increasing the number of cooling channels 212 corresponding to each air channel 22, so as to improve the heat exchange efficiency between the cooling medium in each channel of the cooling channel 212 and the humid and hot air in each air channel 22.

[0095] In one embodiment, as Figure 2 、 Figures 6 to 9 shown, a number of holes 2121 are provided in the cooling channel 212 of the heat exchange member 20, and the holes 2121 communicate with the cavity 11. During the process of flowing out of the cooling medium from a number of holes 2121, it contacts the humid and hot air in the cavity 11 during the flowing process, and can also contact a part of the humid and hot air in the cavity 11 when flowing to the inner wall of the cavity 11 and accumulating on the inner wall of the cavity 11, so as to perform heat exchange with the humid and hot air in the cavity 11. Specifically, the cooling medium introduced into the cooling channel 212 from the cooling medium inlet 14 of the housing 10, part of the cooling medium flows out from a number of holes 2121 during the flowing process in the cooling channel 212, directly contacts the humid and hot air in the cavity 11 to perform heat exchange, and finally this part of the cooling medium falls to the bottom wall of the cavity 11 and is discharged from the drainage pipe 15 of the housing 10 together with the condensed water generated during the cooling of the humid and hot air; part of the cooling medium flows into the cavity 11 from the cooling medium outlet 213, performs heat exchange with the humid and hot air in the cavity 11 contacting the cooling part 21, and is discharged into the cavity 11 from the cooling medium outlet 213, and is discharged from the drainage pipe 15 of the housing 10 together with the condensed water generated during the cooling of the humid and hot air.

[0096] In one embodiment, a plurality of holes 2121 are provided on the bottom wall of the cooling channel 212. When the cooling medium flows out of the holes 2121, it falls under its own gravity, reducing the attachment of the cooling medium to the outer wall of the cooling part 21 during the downward flow, so as not to affect the heat exchange between the outer wall of the cooling part 21 and the humid and hot air.

[0097] In one embodiment, the holes 2121 correspond to the position of the air channel 22, so as to avoid the situation that the holes 2121 correspond to the side wall position of the air channel 22, which affects the outflow of the cooling medium from the holes 2121. Further, by limiting the aperture of the holes 2121, the flow rate of the cooling medium flowing out of the holes 2121 is restricted, so as to prevent the cooling medium from flowing out of the holes 2121 too fast and falling rapidly to the bottom wall of the cavity 11, reducing the contact time between the cooling medium flowing out of the holes 2121 and the humid and hot air in the cavity 11, reducing the utilization rate of the cooling medium, and causing waste of the cooling medium; in addition, controlling the aperture of the holes 2121 to prevent the cooling medium from flowing out of the holes 2121 too slowly, resulting in poor cooling effect by directly contacting the cooling medium with the humid and hot air. It should be understood that the shape of the holes 2121 includes but is not limited to circular, square, and strip-shaped. The "aperture" mentioned above refers to the cross-sectional area equivalent to the area of the holes 2121 with different shapes.

[0098] In one embodiment, a plurality of holes 2121 are distributed on the path leading to the cooling medium outlet 213. After the cooling medium enters the cooling channel 212 from the cooling medium inlet 14 of the housing 10, during the process of flowing towards the cooling medium outlet 213, as the cooling medium absorbs more and more heat from the humid and hot air in the cavity 11, the temperature of the cooling medium becomes higher and higher, until the temperature of the cooling medium reaches the highest when it reaches the cooling medium outlet 213. By distributing a plurality of holes 2121 on the path leading to the cooling medium outlet 213, that is, no holes 2121 are provided between the cooling medium outlet 213 and the end of the cooling channel 213. When the cooling medium flows to the position between the cooling medium outlet 213 and the end of the cooling channel 213, the cooling medium is blocked by the contour of the end of the cooling channel 213 and then flows back to the cooling medium outlet 213 and flows out, so as to prevent the cooling medium from flowing into the cavity 11 when it flows to the position between the cooling medium outlet 213 and the end of the cooling channel 213. At this time, the temperature of the cooling medium is high and it is not conducive to the cooling of the humid and hot air in the cavity 11. Further, a plurality of holes 2121 are evenly distributed on the path leading to the cooling medium outlet 213, so that the cooling medium in the cooling channel 212 is evenly sprinkled onto the humid and hot air in the cavity 11 through the plurality of holes 2121, improving the heat exchange effect.

[0099] In one embodiment, as Figure 9As shown, the diameters of a number of holes 2121 gradually decrease along the flow direction of the cooling medium in the cooling channel 212. The temperature of the cooling medium in the cooling channel 212 gradually increases during the flow process, and the temperature is the highest when it flows to the cooling medium outlet 213. By defining the diameters of the number of holes 2121, the amount of the cooling medium with a high temperature in the cooling channel 212 flowing into the cavity 11 from the holes 2121 is reduced, so as to reduce the influence of the temperature difference of the cooling medium flowing into the cavity 11 from the holes 2121 on the cooling effect of the humid and hot air in the cavity 11.

[0100] In one embodiment, as Figure 5 shown, the moisture exhaust device body 1 is provided with a partition member for separating the cavity 11 into two regions; the cooling part 21 and the humid and hot air are respectively located on both sides of the partition member, so that the cooling part 21 and the humid and hot air entering the cavity 11 are respectively located in two relatively independent spaces, so as to prevent the humid and hot air from forming condensed water during the cooling process, resulting in more moisture contacting the outer wall of the cooling part 21, which is not conducive to the cooling part 21 absorbing the heat of the humid and hot air. Further, in one embodiment, the heat exchange member 20 includes a number of air channels 22 for accommodating the humid and hot air, then the cooling part 21 and the air channels 22 are respectively located on both sides of the partition member, so that the cooling part 21 and the air channels 22 are respectively located in two relatively independent spaces. Specifically, the condensed water formed by the cooling and condensation of the humid and hot air in the air channels 22 will, to a certain extent, cause an increase in the humidity of the space where the air channels 22 are located. Separating the cooling part 21 from the air channels 22, the increase in the humidity of the air channels 22 will not affect the humidity of the environment where the cooling part 21 is located, so as to prevent the increase in the humidity of the environment where the cooling part 21 is located from causing more water molecules to contact the outer wall of the cooling part 21. The cooling part 21 will absorb the heat of the water molecules contacted by its outer wall, thereby affecting the cooling effect of the cooling part 21.

[0101] Further, the periphery of the first wall 214 of the cooling part 21 facing the humid and hot air abuts against the contour of the cavity 11 to form a partition member. Specifically, the periphery of the first wall 214 of the cooling part 21 facing the air channels 22 abuts against the contour of the cavity 11 to form a partition member, without the need to additionally provide a partition member to occupy the space in the cavity 11. Further, both sides of the first wall 214 are respectively in contact with the cooling medium in the cooling channel 212 and the humid and hot air in the air channels 22. The first wall 214 is a heat conducting sheet to improve the speed of transferring the heat of the humid and hot air to the cooling medium in the cooling channel 212 and accelerate the heat exchange efficiency. Further, the first wall 214 is provided with a number of mounting holes 2141, and a number of mounting parts 111 corresponding to the positions of the number of mounting holes 2141 are provided in the cavity 11, so as to fix the heat exchange member 20 in the cavity 11 through fasteners.

[0102] In one embodiment, as Figure 2 、 Figure 5As shown in the figure, the cooling part 21 is provided with an opening; the opening faces the curved cooling channel 212. Since the moisture exhaust device body 1 is used in the dryer body, in order to save costs and simplify the internal structure layout of the dryer body, the cooling medium is cooling water, which is cheap and easy to obtain. The cooling water can be provided to the moisture exhaust device body 1 in time through the water circuit in the dryer body without replacing the cooling medium, and the operation is convenient. The cooling water absorbs heat and its temperature rises. Since the water used in the dryer body usually contains scale-forming ions such as calcium ions and magnesium ions, scale may be generated during the process of the cooling water temperature rising. The setting of the opening of the cooling part can be used to check the formation of scale and clean the scale in time.

[0103] Further, the outer contour of the opening of the cooling part 21 abuts against the inner wall of the housing 10 to form a closed cooling channel 212, so as to prevent the cooling medium inside the cooling channel 212 from leaking. Further, the cooling part 21 is in an open shape to form the opening. The opening contour is large, which is convenient for observing and cleaning the scale in the cooling channel; and when installing the heat exchange part 20, the open end of the cooling part 21 abuts against the inner wall of the housing 10, and the cooling medium in the cooling channel 212 will not overflow from the cooling channel 212. It should be understood that when there is a gap between the outer contour of the opening of the cooling part 21 and the inside of the housing 10, in order to prevent the cooling medium in the cooling channel 212 from leaking from its opening, the opening of the cooling part 21 faces downward.

[0104] Further, the height of the partition 211 is less than the height of the peripheral contour of the cavity, so as to facilitate the processing of the cooling part 21, reduce the requirement for the processing accuracy of the partition 211, and prevent the height of the partition 211 from being higher than the height of the peripheral contour of the cavity during processing, which may affect the outer contour of the opening of the cooling part 21 from abutting against the inner wall of the housing 10, and then the cooling channel 212 cannot be closed. When there is more cooling medium or the flow is relatively fast in the cooling channel 212, it is easy for the cooling medium in the cooling channel 212 to leak from the gap between the outer contour of the opening of the cooling part 21 and the inner wall of the housing 10.

[0105] In one embodiment, as Figures 1 to 5 shown, the housing 10 includes a first housing 16 and a second housing 17; the first housing 16 and the second housing 17 jointly clamp to form a cavity 11. The first housing 16 and the second housing 17 are detachably connected to facilitate the loading and unloading of the heat exchange part 20.

[0106] Embodiment 3

[0107] The present invention provides a dryer, which includes a dryer body for performing drying. The dryer body includes a moisture exhaust device body 1 of the moisture exhaust device for the dryer as described above. The dryer body includes a box body and a drying cylinder; the drying cylinder and the moisture exhaust device body 1 are both arranged in the box body. The air outlet 13 of the moisture exhaust device body 1 is unidirectionally communicated with the external environment of the box body to discharge the hot and humid air in the cavity 11 out of the box body after cooling and dehumidification. When the dryer body executes the drying program, the hot and humid air in the drying cylinder enters the cavity 11 from the air inlet 12. After being cooled by absorbing heat through the cooling part 21, the moisture in the hot and humid air is condensed and removed, and then discharged out of the box body from the air outlet 13. The cooling of the hot and humid air by the cooling part 21 includes the direct contact between the cooling medium flowing out of several holes 2121 and the hot and humid air for cooling, and the cooling medium in the cooling channel 212 absorbs the heat transferred from the hot and humid air to the outer wall of the cooling part 21 for cooling, so as to accelerate the cooling of the hot and humid air. The cooling medium that has absorbed heat in the cooling channel 212 is discharged into the cavity 11 from the cooling medium outlet 213 and discharged from the drain pipe 15 of the housing 10 together with the condensed water, simplifying the pipeline layout structure when the moisture exhaust device body 1 is installed in the dryer body. Through the moisture exhaust device body 1, the hot and humid air generated by the drying cylinder is cooled and dehumidified and then discharged into the external environment, instead of directly discharging the hot and humid air generated by the drying cylinder out of the box body, which may cause an increase in the humidity and temperature of the external environment of the box body, affecting the external environment parameters of the dryer body and resulting in poor user experience, and is not conducive to the preservation of furniture in the same environment. The water outlet 151 of the moisture exhaust device body 1 faces the side of the housing 10 to facilitate the connection between the drain pipe 15 of the moisture exhaust device body 1 and the pipeline of the dryer body.

[0108] Further, the dryer body further includes a heater and a blower. The heater is used to heat the air, and the blower is used to introduce the dried air heated by the heater into the drying cylinder to dry the clothes placed in the drying cylinder.

[0109] In an embodiment, the cooling medium is cooling water. The cooling medium inlet 14 of the moisture exhaust device body 1 is connected to the water inlet valve in the dryer body to introduce cooling water; the drain pipe 15 of the moisture exhaust device body 1 is communicated with the drain pipe of the dryer body.

[0110] In one embodiment, the dryer body includes a condenser; the drain pipe 15 of the moisture exhaust device body 1 is communicated with the condenser to introduce the condensed water formed during the cooling process of the hot and humid air discharged from the drain pipe 15 into the condenser as a cooling medium. In one embodiment, the cooling medium outlet 213 of the cooling part 21 is communicated with the cavity 11, and the cooling water after absorbing heat and the condensed water are jointly discharged from the drain pipe 15 and then introduced into the condenser as a cooling medium. Specifically, the condenser is used to condense the hot and humid air entering the condenser from the drying drum to form dry air, which is provided to the heater in the dryer body. The dry air is heated by the heater and then introduced into the drying drum to continue drying the clothes, so as to dehumidify the hot and humid air with a relatively high temperature generated in the drying drum and recycle the dry air. Specifically, the cooling water that has absorbed the heat of the hot and humid air discharged from the cooling medium outlet 213 of the cooling channel 212 falls onto the inner bottom wall of the housing 10. After being collected with the condensed water, it is discharged from the drain pipe 15. The drain pipe 15 of the moisture exhaust device body 1 is communicated with the condenser to introduce the cooling water and condensed water that have absorbed the heat of the hot and humid air in the moisture exhaust device body 1 into the condenser as the cooling medium of the condenser. The water outlet 151 of the drain pipe 15 is arranged towards the side of the housing 10 to facilitate the connection between the drain pipe 15 of the moisture exhaust device body 1 and the condenser; specifically, the moisture exhaust device body 1 and the condenser are respectively arranged on both sides of the drying drum, and the water outlet 151 of the drain pipe 15 of the moisture exhaust device body 1 faces the condenser for connection with the condenser.

[0111] Further, in order to save energy consumption and speed up drying, an intake valve and a temperature and humidity sensor are provided at the air inlet 12 of the moisture exhaust device body 1. When the dryer body performs drying, the condenser and the water inlet valve are first turned on, and cooling water is introduced into the cooling medium inlet 14. At this time, the humid and hot air in the drying cylinder only enters the condenser; the water inlet valve of the dryer body introduces cooling water into the cooling part 21 of the moisture exhaust device body 1. At this time, the humid and hot air generated by the drying cylinder is not introduced into the moisture exhaust device body 1, and the cooling water in the moisture exhaust device body 1 is discharged from the drain pipe 15 into the condenser to cool and dehumidify the humid and hot air introduced into the condenser from the drying cylinder. When the temperature of the air in the drying cylinder drops to the temperature threshold set by the temperature and humidity sensor at the air inlet 12, the intake valve is opened. Part of the humid and hot air in the drying cylinder enters the condenser, and part enters the moisture exhaust device body 1. The humid and hot air generated in the drying cylinder is processed by the condenser and the moisture exhaust device body 1 at the same time to speed up the drying process; at this time, since the temperature of the humid and hot air in the drying cylinder has decreased, the heat absorbed by the cooling water after the humid and hot air enters the moisture exhaust device body 1 decreases, and the temperature of the cooling water after absorbing the heat of the humid and hot air increases, but the increase range is not high, and the temperature difference from the humid and hot air generated by the drying cylinder at this time is still large. Therefore, after the cooling water absorbed heat in the moisture exhaust device body 1 is discharged from the drain pipe 15 into the condenser, it can still cool the humid and hot air in the condenser and ensure a certain cooling speed. Part of the humid and hot air generated by the drying cylinder is introduced into the cavity 11 of the moisture exhaust device body 1 for cooling and dehumidification treatment, and part is introduced into the condenser for condensation dehumidification and recovery of dry air, which improves the processing speed of the relatively high-temperature humid and hot air generated by the drying cylinder. In addition, the cooling water provided by the water inlet valve of the dryer body is reused to save water. In one embodiment, the condenser further includes a medium inlet (not shown in the figure), which is connected to the water inlet valve in the dryer body to introduce cooling water and improve the cooling speed of the condenser.

[0112] In yet another embodiment, the drain pipe 15 is communicated with the drain pipe of the dryer body to discharge the liquid discharged from the drain pipe 15 out of the dryer body. In yet another embodiment, a collection box communicated with the drain pipe 15 is provided in the dryer body to collect the liquid discharged from the drain pipe 15.

[0113] Compared with the prior art, the moisture exhaust device for a dryer provided by the present invention is convenient for connecting the drain pipe of the device with the pipe of the dryer body after the moisture exhaust device body is installed around the drying cylinder by arranging the water outlet of the drain pipe toward the side of the housing.
