Abstract
Description
Technical Field
[0001] This application relates to the field of clothing drying equipment, and more particularly to a clothes drying device. Background Technology
[0002] A condenser washer-dryer combo is a home appliance that integrates washing and drying functions into one machine. It combines the washing function of a washing machine with the drying function of a dryer, allowing the entire process of washing and drying clothes to be completed in one machine.
[0003] During the drying process, heated air is blown into the washing tub, causing the moisture in the clothes to evaporate into water vapor. The hot air containing water vapor is cooled and condensed into liquid water as it passes through a condenser, which is then discharged from the machine through a drainage system, thus drying the clothes.
[0004] Existing technology continuously flows cooling water to the surface of the condenser plate, and the cooling water cools the condenser plate by contacting it. However, when the cooling water flows to the condenser plate, some of the cooling water is lost directly without contacting the condenser plate, resulting in low cooling water utilization. Utility Model Content
[0005] In view of this, the purpose of this application is to provide a clothes drying device to solve the technical problem of low cooling water utilization rate for cooling condenser plates in the prior art.
[0006] To achieve at least one of the above objectives, this application provides the following technical solution:
[0007] This application provides a clothes drying device, including an outer drum, an inner drum, a drying air duct, a condenser tray, and a water supply assembly. The inner drum is rotatably disposed inside the outer drum via a rotating shaft, and has a drying chamber capable of accommodating clothes. The cavity between the inner drum and the outer drum is a first cavity. The drying air duct is disposed outside the outer drum and has a return air inlet and an air outlet. The return air inlet is located at the rear end of the outer drum and communicates with the first cavity, while the air outlet is located at the front end of the outer drum and communicates with the drying chamber. The drying air duct is configured to supply gas for drying clothes into the drying chamber and to extract gas from the first cavity. The condenser tray includes a tray body located inside the inner wall of the outer drum. The tray body is configured to condense water vapor in the gas flowing over its surface into water. The tray body has a cooling channel with an inlet and an outlet. The water supply assembly is used to supply cooling water to the cooling channel, allowing the cooling water to enter the cooling channel from the inlet and flow out from the outlet.
[0008] In the above technical solution, by setting the condenser plate on the rear wall, when the hot and humid air in the drying chamber flows through the condenser plate, the condenser plate absorbs the heat of the hot and humid air, cools the hot and humid air, and causes some water vapor to condense into liquid water, reducing the humidity of the air entering the drying duct from the return air inlet. After the air is heated in the drying duct, it re-enters the drying chamber from the air outlet to dry the clothes, thus achieving rapid drying of the clothes.
[0009] By sending cooling water into the cooling channel through the water supply assembly, the cooling water can be guaranteed to make full contact with the condenser plate when flowing in the cooling channel, while reducing or avoiding the situation where the cooling water is directly lost without contacting the condenser plate; the longer contact time between the cooling water and the condenser plate improves the cooling efficiency of the cooling water on the condenser plate, increases the utilization rate of the cooling water, and reduces the amount of cooling water used.
[0010] One end of the water supply component is connected to the cooling channel, and the other end is connected to the water pipe that supplies cooling water outside the outer cylinder. This allows external cooling water to be sent into the cooling channel. After the water in the cooling channel cools the plate, it flows out of the plate from the outlet. The water supply component and the outlet enable the continuous supply and flow of external cooling water into and out of the cooling channel to continuously cool the plate.
[0011] In some embodiments, the water delivery assembly includes an inlet and a cover. The inlet is located on the rear end wall, which is the rear wall of the outer cylinder. A groove is provided on the side of the rear end wall facing the inner cylinder and communicates with the inlet. The cover is fixed on the side of the rear end wall facing the disc and covers the groove, forming a water passage cavity. One end of the first pipeline communicates with the inlet, and the other end passes through the cover and communicates with the water passage cavity.
[0012] In the above technical solution, the water supply component is divided into three sections: the liquid inlet on the rear wall, the water passage cavity, and the first pipeline. Cooling water flows sequentially through the liquid inlet, the water passage cavity, and the first pipeline into the cooling channel to cool the plate.
[0013] The water passage cavity facilitates the setting of the inner diameter of the first pipe, which can be the same as or different from the diameter of the liquid inlet. On the other hand, it also provides a water storage space. External cooling water enters the water passage cavity for storage before being sent to the cooling channel through the first pipe. This reduces fluctuations in the flow rate of the external cooling water, making the water flow in the first pipe more stable. This results in a stable flow rate of cooling water entering the cooling channel from the first pipe, and a stable cooling effect of the cooling water on the tray, which helps in the control of the drying equipment.
[0014] In some embodiments, the water inlet is located on the side of the disc facing the rear end wall.
[0015] In the above technical solution, the water supply component is set on the rear wall, and the water supply component is connected to the water inlet set on the side of the tray facing the rear wall. This can reduce the length of the water supply component and reduce the gap between the rear wall and the tray, making the internal structure of the drying equipment compact and helping to increase the effective space inside the drying equipment.
[0016] In some embodiments, the cover includes an annular connecting edge that protrudes from the surface of the cover toward the rear end wall and is disposed around the outside of the groove.
[0017] In the above technical solution, the annular connecting edge can provide a relatively closed space after contacting the rear end wall, and the groove is designed to form a water passage cavity; this ensures the formation of the water passage cavity and reduces the leakage of cooling water from the gaps around the water passage cavity, thus reducing the utilization rate of cooling water.
[0018] In some embodiments, the cover further includes a sealing strip disposed between the annular connecting edge and the rear end wall.
[0019] In the above technical solution, the sealing strip is set between the annular connector and the rear end wall, which facilitates the installation of the sealing strip. The sealing strip ensures the sealing effect after the water passage cavity is formed, prevents cooling water from leaking from the gaps around the water passage cavity, helps to improve the utilization rate of cooling water and reduce the use of cooling water.
[0020] In some embodiments, the disc body is a fan-shaped component coaxial with the rotation axis, and the water inlet is located at the center of the disc body along its circumference, directly above the rotation axis.
[0021] In the above technical solution, after the cooling water enters the cooling channel from the inlet, it flows downwards while also flowing along the circumference of the disc towards both ends of the disc. This helps the cooling water to spread relatively evenly to all areas of the disc, improving the cooling efficiency of the cooling water on the disc.
[0022] In some embodiments, multiple water outlets are provided, and the multiple water outlets are respectively located at both ends of the disc body along its circumference.
[0023] In the above technical solution, the setting of multiple water outlets can reduce the resistance of the cooling water flowing out of the cooling channel after heating, which helps the cooling water flow in the cooling channel.
[0024] By placing multiple water outlets at both ends of the plate along its circumference, it helps to distribute the cooling water relatively evenly to all parts of the plate, which helps to improve the cooling efficiency of the cooling water to the plate and the uniformity of cooling to all parts of the plate.
[0025] In some embodiments, the disc body is a semi-annular component.
[0026] In the above technical solution, since the disc is a semi-circular component fixed above the rotating shaft, when the cooling water flows out of the disc from the outlet, a water curtain will be formed below the disc. When the hot and humid air comes into contact with the water curtain, it can exchange heat with the water curtain, which increases the heat exchange between the cooling water and the hot and humid air, thereby helping to improve the condensation effect of the hot and humid air.
[0027] In some embodiments, the cooling channels are interconnected network channels.
[0028] In the above technical solution, the open network-like cooling channel helps the cooling water flow along the cooling channel to various areas of the plate, which helps to improve the uniformity of the contact between the cooling water and the plate, so that the cooling water has a relatively consistent cooling effect on all parts of the plate.
[0029] In some embodiments, the side of the disc facing the inner cylinder has a protrusion, and a cooling channel is provided at the protrusion.
[0030] In the above technical solution, the protrusion helps to increase the contact area between the disc and the humid air, increase the heat exchange between the disc and the humid air, and help improve the condensation effect of the disc on the humid air.
[0031] The cooling channel is located in a raised position. After the raised part of the plate absorbs the heat from the hot and humid air, it can quickly transfer the heat to the cooling water in the cooling channel, which helps to improve the utilization rate of cooling water and reduce the amount of cooling water used.

[0065] As part of the inventive concept of this application, before describing the embodiments of this application, it is necessary to analyze the reasons for the low cooling water utilization rate in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.
[0066] The drying equipment involved in this application adopts a condenser drying mode, which differs from direct-vent drying and has unique working principles and technical advantages. The condenser drying mode achieves clothing drying by constructing a closed-loop heat circulation system.
[0067] In condenser drying mode, hot air heated by the heating device circulates directionally within a sealed drying chamber, making full contact with the clothes to be dried and causing the moisture in the clothes to quickly vaporize into water vapor. Subsequently, the humid hot air carrying the water vapor enters the condensation system. Under the action of the condensation device, the water vapor undergoes a phase change upon cooling, recondensing into liquid water and being discharged from the equipment through the drainage system. The dry air that has completed water vapor separation then flows back to the heating device for secondary heating, forming a continuous cycle of drying process.
[0068] The condensation drying mode effectively avoids the heat loss problem of traditional direct-vent drying, and achieves efficient recycling of heat energy.
[0069] During the preheating phase of the dryer: After the dryer is started, the heating element enters its working state first, heating the air to the set temperature range. This temperature parameter is precisely set according to the fabric of the clothes and the drying program to ensure effective drying while avoiding high-temperature damage to the fabric.
[0070] During the circulating drying stage: a fan directs preheated hot air into the inner drum of the equipment, where the hot air exchanges heat and moisture thoroughly with the clothes, promoting rapid evaporation of moisture. During the drying process, the inner drum rotates periodically under the control system, achieving three-dimensional heating of the clothes through mechanical tumbling. This effectively avoids localized overheating and overdrying, while simultaneously increasing the contact area between the hot air and the clothes, significantly improving drying efficiency.
[0071] In the water vapor separation stage: humid, hot air carrying a large amount of water vapor is transported to the condenser pan via the guide system. The condenser pan rapidly absorbs heat from the humid air through a highly efficient heat exchange mechanism, causing the water vapor to liquefy on its surface, forming liquid water which is then discharged from the equipment through the drain pipe. The dried air that has completed water vapor separation re-enters the heating device to begin a new cycle.
[0072] The drying equipment is also equipped with a drying sensor system to monitor the temperature and humidity parameters inside the drying chamber in real time. The humidity sensor uses capacitive or resistive sensing technology to accurately detect the moisture content of the clothes; the temperature sensor uses thermocouples or resistance temperature detectors (RTDs) to collect the temperature data inside the chamber in real time.
[0073] When the humidity sensor detects that the moisture content of the clothes has reached the preset drying threshold, or the temperature sensor detects that the temperature exceeds the safe upper limit, the control system will immediately activate the graded response mechanism: firstly, it will dynamically adjust the drying parameters by adjusting the power output of the heating device and the fan speed; if the abnormal situation continues or exceeds the safe range, it will automatically trigger the shutdown protection program to ensure the safe operation of the equipment and the drying quality of the clothes.
[0074] This embodiment describes a dryer-dryer combo, which includes a washing system, a drying system, a control system, a support system, and a water supply and drainage system. The drying system begins operation after the washing system's spin-drying cycle is complete.
[0075] The technical solution disclosed in this application can also be used in dryers, but will not be described in detail in this embodiment.
[0076] When hot, humid air comes into contact with the condenser, the condenser absorbs heat from the hot, humid air. When some of the water vapor in the hot, humid air liquefies, the temperature of the condenser rises, requiring the condenser to be cooled to maintain a temperature difference between the condenser and the hot, humid air, allowing the condenser to continuously absorb heat from the hot, humid air.
[0077] Cooling the condenser pan involves spraying cooling water onto its surface. The cooling water comes into contact with the condenser pan and flows across its surface, absorbing heat from the condenser pan and thus cooling it down.
[0078] When cooling water is sprayed onto the surface of the condenser plate, only a portion of the cooling water can contact the condenser plate and flow along its surface. Some cooling water does not contact the condenser plate and drips off without continuously flowing along its surface. Therefore, the utilization rate of cooling water used to cool the condenser plate is low, and the water consumption of the drying equipment is high during operation.
[0079] Therefore, this application provides a clothes drying device, including an outer drum, an inner drum, a drying air duct, and a condenser tray. The inner drum is rotatably disposed inside the outer drum via a rotating shaft, and the interior of the inner drum has a drying chamber capable of accommodating clothes. The cavity between the inner drum and the outer drum is a first cavity.
[0080] The drying air duct is located outside the outer cylinder. The drying air duct has a return air inlet and an air outlet. The return air inlet is located at the rear end of the outer cylinder and is connected to the first cavity. The air outlet is located at the front end of the outer cylinder and is connected to the drying cavity.
[0081] The drying duct is configured to supply gas for drying clothes into the drying chamber and to extract gas from the first chamber.
[0082] A condenser includes a plate body located inside the inner wall of the outer cylinder. The plate body is configured to condense water vapor in the gas flowing over its surface into water. The plate body has an internal cooling channel with an inlet and an outlet.
[0083] The water supply assembly is used to supply cooling water to the cooling channel, allowing the cooling water to enter the cooling channel from the inlet and flow out from the outlet.
[0084] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.
[0085] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0086] For ease of explanation, a first direction, a second direction, and a third direction are defined, where the first direction is the axial direction of the rotation axis, the second direction is the width direction of the dryer, and the third direction is the height direction of the dryer when it is normally placed. In the attached drawings, the first direction is represented by the X direction, the second direction by the Y direction, and the third direction by the Z direction.
[0087] Figure 1 A three-dimensional structural diagram of a clothes drying device is provided. Specifically, the clothes drying device also includes a housing 1, which is the outer shell of the clothes drying device. The housing 1 has a hollow rectangular parallelepiped structure, and its shape can be designed as needed and is not limited here. A receiving cavity is provided inside the housing 1, which provides installation space for components such as the outer drum 2, the inner drum 4, and the drying air duct 5. (Refer to...) Figure 2 .
[0088] Reference Figure 1 The container 1 is provided with a dispensing port 11, which is roughly circular and located at the front end of the container 1. The dispensing port 11 is connected to the receiving cavity.
[0089] A door 12 is installed on the housing 1. The door 12 is hinged to the housing 1 near the dispensing port 11. The door 12 can rotate to close the dispensing port 11. The door 12 can rotate away from the dispensing port 11 to open the dispensing port 11. When the dryer is running, the door 12 closes the dispensing port 11.
[0090] Reference Figure 2 The outer cylinder 2 is located inside the receiving cavity of the box body 1. The outer cylinder 2 is a shell structure with an open front end. The opening at the front end of the outer cylinder 2 is the first cylinder opening, which is connected to the inner cavity of the outer cylinder 2 and is positioned opposite to the delivery port 11.
[0091] Reference Figure 2 Specifically, the outer cylinder 2 can be formed by an outer peripheral wall 22 and a rear end wall 21. The outer peripheral wall 22 is a cylindrical structure, and a first cylinder opening is provided at the front end of the outer peripheral wall 22. The rear end wall 21 is sealed and fixed to the rear end of the outer peripheral wall 22, and the rear end wall 21 is arranged opposite to the first cylinder opening.
[0092] An air vent is provided on the rear wall 21, which is connected to the drying air duct 5. The gas in the inner cavity of the outer cylinder 2 flows into the drying air duct 5 through the air vent.
[0093] A door seal ring 3 is also provided between the first cylinder opening and the inlet 11. The door seal ring 3 is roughly in the shape of a circular ring and can seal the gap between the first cylinder opening and the inlet 11 to prevent water in the outer cylinder 2 from flowing into the receiving cavity of the tank 1.
[0094] Reference Figure 2 In this embodiment, the inner cylinder 4 is disposed in the inner cavity of the outer cylinder 2. The inner cylinder 4 is rotatably connected to the rear end wall 21 of the outer cylinder 2 via a rotating shaft 42. The rotating shaft 42 passes through the rear end wall 21 from front to back, and the inner cylinder 4 and the outer cylinder 2 are arranged coaxially inside and outside.
[0095] Specifically, the inner cylinder 4 is a shell structure with an open front end. A drying chamber 41 is formed inside the inner cylinder 4. The drying chamber 41 can hold clothes. The opening at the front end of the inner cylinder 4 is a second cylinder opening. The second cylinder opening is connected to the drying chamber 41, and the second cylinder opening and the first cylinder opening are spaced apart along a first direction.
[0096] After the door 12 is opened, clothes can be put into the drying chamber 41 through the inlet 11, the first cylinder inlet and the second cylinder inlet, or clothes can be taken out of the drying chamber 41.
[0097] The inner cylinder 4 includes a first cavity 23, which is the cavity between the inner cylinder 4 and the outer cylinder 2. A through hole 43 is provided on the side wall of the inner cylinder 4, allowing the drying chamber 41 to communicate with the first cavity 23. (Refer to...) Figure 3 .
[0098] Since the air vent on the rear wall 21 is exposed inside the first cavity 23, the drying cavity 41 can be connected to the air vent via the first cavity 23.
[0099] In this embodiment, refer to Figure 2 as well as Figure 3 The drying air duct 5 is located outside the outer cylinder 2. The drying air duct 5 has a return air inlet and an air outlet. Along the first direction, one end of the drying air duct 5 is the return air inlet and the other end is the air outlet. The return air inlet is located on the rear wall of the outer cylinder 2 and communicates with the first cavity 23. The air outlet is located at the front end of the outer cylinder 2 and communicates with the drying cavity 41.
[0100] Specifically, the drying air duct 5 is connected to the drying chamber 41 in the following way: the drying air duct 5 passes through the door seal ring 3 along the first direction toward the front end of the door body 12.
[0101] The return air inlet is connected to the air outlet on the rear end wall 21, and the air outlet is connected to the drying chamber 41, so that the drying chamber 41, the first chamber 23, and the drying air duct 5 can form an air drying circulation loop.
[0102] The drying duct 5 is configured to supply gas for drying clothes into the drying chamber 41 and to extract gas from the first chamber 23 through the return air vent.
[0103] Reference Figure 2 as well as Figure 4 Specifically, a heating device 51 and a fan 52 are installed inside the drying duct 5. The heating device 51 is configured to heat the air inside the drying duct 5 and increase the temperature of the air inside the drying duct 5.
[0104] The fan 52 is used to provide airflow so that air enters the drying duct 5 through the air inlet on the rear end wall 21, and the high-temperature air in the drying duct 5 can enter the drying chamber 41 of the inner drum 4. The hot air in the drying chamber 41 dries the clothes in the drying chamber 41.
[0105] Reference Figure 2 as well as Figure 6 In this embodiment, the clothes drying device also includes a condenser tray 6, which is disposed on the side of the rear end wall 21 facing the inner cylinder 4.
[0106] The condenser plate 6 is configured as a condenser. The condenser plate 6 cools the air flowing from the inner cavity of the outer cylinder 2 through the air inlet of the rear end wall 21 into the drying air duct 5, so that the water vapor in the hot and humid air is condensed into liquid water, thereby achieving dehumidification of the air flowing through the condenser plate 6.
[0107] When the drying equipment is working, the air in the first chamber 23 exchanges heat with the condenser plate 6 to remove moisture from the air and lower the air temperature. Then the air enters the drying air duct 5 from the return air vent.
[0108] Specifically, the high-temperature air from the drying duct 5 enters the drying chamber 41, heats the clothes inside the drying chamber 41, removes the moisture from the clothes, and forms humid and hot air. The humid and hot air enters the first chamber 23 through the through hole 43 on the inner cylinder 4 and can flow through the condenser plate 6 on the rear end wall 21. The humid and hot air comes into contact with the condenser plate 6 to exchange heat, so that the moisture in the humid and hot air condenses on the condenser plate 6.
[0109] After being condensed and dehumidified by the condenser plate 6, the air enters the drying duct 5 through the return air inlet and is reheated before being sent into the drying chamber 41 to realize the drying cycle of the drying equipment. After multiple cycles, the clothes can be dried.
[0110] During the dehumidification process of the air in the inner cavity of the outer cylinder 2, the temperature of the condenser plate 6 rises after exchanging heat with the humid and hot air. In order to ensure the condensation efficiency of the condenser plate 6, cooling measures need to be taken for the condenser plate 6.
[0111] Reference Figure 5An inlet 24 can be provided on the rear wall 21 of the outer cylinder 2, and a drain 25 can be provided at the bottom of the outer cylinder 2. The inlet 24 can be connected to an inlet pipe to guide the cooling water supplied by the inlet pipe into the outer cylinder 2, where it contacts the condenser 6 for heat exchange, cooling the condenser 6. The cooling water flows through the condenser and is discharged through the drain 25. In this embodiment, the inlet pipe is connected to a municipal water pipe.
[0112] Reference Figure 7 The condenser plate 6 includes a plate body 61 located inside the inner wall of the outer cylinder 2. The plate body 61 is configured to condense water vapor in the gas flowing over its surface into water. The plate body 61 has an internal cooling channel 62 with an inlet 621 and an outlet 622. A water supply assembly 7 is used to supply cooling water to the cooling channel 62, allowing the cooling water to enter the cooling channel 62 from the inlet 621 and flow out from the outlet 622.
[0113] The condenser plate 6 includes a plate body 61, which is located inside the outer cylinder 2. The plate body 61 is laid on the rear end wall 21. A cooling channel 62 is constructed on the plate body 61. The cooling channel 62 has an inlet 621 and an outlet 622 that communicate with the outside.
[0114] For example, the disc body 61 is fixed to the rear end wall 21, which is the rear wall of the outer cylinder 2. The specific fixing method can be set as needed. In this embodiment, the disc body 61 is detachably fixed to the rear end wall 21 using bolts.
[0115] Reference Figure 9 as well as Figure 10 For example, the disc body 61 is a composite metal plate structure. The disc body 61 includes two plates stacked along the thickness direction. The two plates are welded and fixed together, and a pipe with a specific structural shape is formed between the two plates. This pipe is a cooling channel 62.
[0116] The cooling channel 62 has an inlet 621 and an outlet 622 that are connected to the outside. After the cooling water enters the cooling channel 62 through the inlet 621, it flows in the cooling channel 62 and cools the plate 61. The cooled water with the increased temperature flows out of the cooling channel 62 through the outlet 622. The cooling water continuously enters the cooling channel 62 to achieve continuous cooling of the plate 61.
[0117] In another embodiment, the disc body 61 may be a one-piece plastic structure.
[0118] Reference Figure 7 As an alternative, the disc 61 is a fan-shaped component coaxial with the rotation shaft 42, and the water inlet 621 is located in the middle of the disc 61 along its own circumference, directly above the rotation shaft 42.
[0119] For example, the disc 61 is an annular component, with its axis along a first direction and coaxial with the rotation axis 42. The center of the disc 61 along its circumference is located directly above the center line of the rotation axis 42. The water inlet 621 is located at the center of the disc 61 along its circumference.
[0120] After the cooling water enters the cooling channel 62 from the inlet 621, it flows downwards and at the same time flows along the circumference of the disc 61 to both ends of the disc 61, and the amount of water flowing along both ends is basically the same.
[0121] The annular disc 61 helps the cooling water to spread relatively evenly to all areas of the disc 61, thereby improving the cooling efficiency of the cooling water on the disc 61.
[0122] Reference Figures 9 to 11 As an optional solution, multiple water outlets 622 are provided, and the multiple water outlets 622 are respectively located at both ends of the disc body 61 along its own circumference.
[0123] For example, a total of ten water outlets 622 are provided. Five water outlets 622 are provided at both ends of the disc body 61 along its circumference. The water outlets 622 are arranged sequentially from the center of the disc body 61 to the outer edge of the disc body 61.
[0124] By setting multiple water outlets 622 at both ends of the disc 61 along its circumference, it helps to distribute the cooling water relatively evenly to all parts of the disc 61, which helps to improve the cooling efficiency of the cooling water to the disc 61 and the uniformity of cooling of all parts of the disc 61.
[0125] Reference Figure 7 As an alternative, the disc 61 is a semi-annular component. Exemplarily, the disc 61 is located in the upper half of the rear end wall 21.
[0126] When the cooling water flows out of the plate 61 from the outlet 622, it forms a water curtain below the plate 61. When the hot and humid air comes into contact with the water curtain, it can exchange heat with the water curtain, which increases the heat exchange between the cooling water and the hot and humid air, thereby helping to improve the condensation effect of the hot and humid air.
[0127] In another embodiment, the disc 61 is an annular member with a notch, the curvature of which is determined according to design requirements.
[0128] Reference Figure 9 As an alternative, cooling channel 62 is an interconnected network of channels.
[0129] For example, the cooling channel 62 includes a plurality of arcuate channels about the rotation axis 42, and two adjacent arcuate channels along the radial direction of the disk body 61 are connected by a plurality of radial channels along the radial direction of the disk body 61.
[0130] The open network-like cooling channel 62 helps the cooling water flow along the cooling channel 62 to all areas of the plate 61, which helps to improve the uniformity of the contact between the cooling water and the plate 61, so that the cooling water has a relatively consistent cooling effect on all parts of the plate 61.
[0131] Reference Figure 9 As an alternative, the side of the disc 61 facing the inner cylinder 4 has a protrusion 611, and the cooling channel 62 is located at the position of the protrusion 611.
[0132] For example, the cooling channels 62 are all located at the protrusions 611, and the wall thickness of the plate 61 where the cooling channels 62 are located is equal to half the thickness of the plate 61.
[0133] When producing the disc body 61, before welding the two plates that make up the disc body 61, the plates facing the inner cylinder 4 are stamped at corresponding positions along the thickness direction to form protrusions 611. After the two plates are welded, the cooling channel 62 is formed.
[0134] In this embodiment, the disk body 61 has protrusions 611 on both sides along the thickness direction. During production, the two plates are stamped separately, then stacked and welded together to form the cooling channel 62.
[0135] The protrusion 611 helps to increase the contact area between the disc 61 and the humid air, increase the heat exchange between the disc 61 and the humid air, and help improve the condensation effect of the disc 61 on the humid air.
[0136] The cooling channel 62 is located at the protrusion 611. After the protrusion 611 of the plate 61 absorbs the heat of the humid air, it can quickly transfer the heat to the cooling water in the cooling channel 62, which helps to improve the utilization rate of the cooling water and reduce the amount of cooling water used.
[0137] Reference Figure 8 as well as Figure 12 One end of the water supply component 7 is connected to the water inlet 621, and the other end passes through the outer cylinder 2, which is used to send cooling water into the cooling channel 62.
[0138] For example, the water supply assembly 7 is used to supply cooling water from outside the outer cylinder 2 into the cooling channel 62 of the condenser plate 6 inside the outer cylinder 2. One end of the water supply assembly 7 is connected to the water inlet 621, and the other end is located outside the outer cylinder 2 and is connected to the municipal water pipe through a pipeline.
[0139] The water supply component 7 delivers municipal water into the cooling channel 62, enabling the cooling water to cool the pan 61. After the water in the cooling channel 62 has cooled the pan 61, it flows out of the pan 61 from the outlet 622. The water supply component 7 continuously delivers external cooling water into the cooling channel 62. The arrangement of the water supply component 7 and the outlet 622 ensures that the water in the cooling channel 62 continuously flows out of the cooling channel 62 from the outlet 622, achieving continuous cooling of the pan 61.
[0140] In another embodiment, the water delivery assembly 7 passes through the outer peripheral wall 22, and the water inlet 621 is located on the side of the disc 61 facing the rear end wall 21.
[0141] In another embodiment, the water delivery assembly 7 passes through the outer peripheral wall 22, and the water inlet 621 is located on the side wall of the disc body 61.
[0142] Reference Figure 12 As an optional solution, the water supply assembly 7 includes an inlet 24, a groove 25, a cover 71, and a first pipe 72. The inlet 24 is located on the rear end wall 21.
[0143] The groove 25 is located on the side of the rear end wall 21 facing the inner cylinder 4, and the groove 25 is connected to the liquid inlet 24.
[0144] The cover 71 is fixed to the side of the rear wall 21 facing the disc 61. The cover 71 covers the groove 25 and forms a water passage cavity 74 with the groove 25. The water passage cavity 74 is a closed chamber that communicates with the liquid inlet 24. One end of the first pipeline 72 is connected to the water inlet 621, and the other end passes through the cover 71 and communicates with the water passage cavity 74.
[0145] For example, the inlet 24 extends through the rear end wall 21 along a first direction. The end of the inlet 24 away from the disc 61 is sealed and connected to a water pipe that is connected to a municipal water pipe.
[0146] The cover 71 contacts the side of the rear end wall 21 facing the disc body 61, and the cover 71 is detachably fixed to the rear end wall 21 using bolts.
[0147] The first pipe 72 is arranged along the first direction. The height of the first pipe 72 is lower than the height of the liquid inlet 24. One end of the first pipe 72 passes through the cover 71 and is welded and fixed to the cover 71. The other end is connected to the water inlet 621 on the plate body 61 in a sealed plug-in connection.
[0148] By dividing the water supply assembly 7 into three sections, namely the liquid inlet 24 on the rear wall 21, the water passage 74, and the first pipe 72, cooling water flows sequentially into the cooling channel 62 through the liquid inlet 24, the water passage 74, and the first pipe 72 to cool the plate 61.
[0149] The water passage 74 is designed to facilitate the setting of the inner diameter of the first pipe 72. The inner diameter of the first pipe 72 can be the same as or different from the diameter of the liquid inlet 24.
[0150] The water passage 74 also provides a water storage space, reducing fluctuations in water flow speed and making the water flow into the first pipe 72 more stable. This results in a stable flow rate of cooling water entering the cooling channel 62 from the first pipe 72, and a stable cooling effect of the cooling water on the plate 61, which helps in the control of the drying equipment.
[0151] Reference Figure 8 as well as Figure 12 As an alternative, the inlet 621 is located on the side of the disc 61 facing the rear end wall 21.
[0152] The water delivery component 7 is installed on the rear end wall 21 and is connected to the water inlet 621 located on the side of the plate 61 facing the rear end wall 21. This reduces the length of the water delivery component 7 and the gap between the rear end wall 21 and the plate 61.
[0153] The compact internal structure of the clothes drying equipment helps to maximize the effective space inside the equipment.
[0154] Reference Figure 12 As an alternative, the cover 71 includes an annular connecting edge 711, which protrudes from the surface of the cover 71 toward the rear end wall 21 and is disposed around the outside of the groove 25.
[0155] For example, the groove 25 is an arc-shaped groove, and the groove 25 and the cover 71 form a water passage cavity 74. The shape of the water passage cavity 74 is similar to half of a teardrop shape, which is larger at the top and smaller at the bottom.
[0156] The annular connecting edge 711 provides a relatively enclosed space after contacting the rear end wall 21. The groove 25 forms a water passage cavity 74, which not only ensures the formation of the water passage cavity 74, but also reduces the leakage of cooling water from the gaps around the water passage cavity 74, thus reducing the utilization rate of cooling water.
[0157] Reference Figure 12 As an optional solution, the cover 71 also includes a sealing strip 73, which is disposed between the annular connecting edge 711 and the rear end wall 21.
[0158] For example, the sealing strip 73 is an annular sealing strip 73, and the annular connecting edge 711 is provided with an annular groove on the surface that contacts the rear end wall 21, and the sealing strip 73 is embedded in the annular groove.
[0159] After the cover 71 is fixed on the rear end wall 21, the annular connecting edge 711 presses the sealing strip 73 tightly onto the rear end wall 21.
[0160] The sealing strip 73 is set between the annular connector and the rear end wall 21, which facilitates the installation of the sealing strip 73. The sealing strip 73 ensures the sealing effect of the water passage cavity 74 after it is formed, preventing cooling water from leaking from the gaps around the water passage cavity 74, which helps to improve the utilization rate of cooling water and reduce the use of cooling water.
