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] As people's living standards improve, consumers have higher demands for the functionality and convenience of home appliances. Clothes dryers are electrical appliances that quickly remove moisture from clothes through heating, ventilation, and other methods, and are widely used in daily life. Using clothes dryers allows clothes to dry quickly, eliminating the need to wait a long time for them to air dry, greatly saving time and allowing people to manage their daily lives more efficiently. They can be used anytime, anywhere, without being limited by weather or space.
[0003] When the drying system is running, the heating device heats the air, and the fan blows the hot air into the inner drum. The hot air causes the moisture in the clothes to evaporate and turn into water vapor. When the hot and humid air flows to the condenser, the condenser quickly absorbs the heat of the hot and humid air, and the moisture in the hot and humid air liquefies on the condenser. The hot air continues to flow to the heating device for heating.
[0004] The condenser trays used in existing technologies cannot meet the needs of rapid drying, resulting in a long drying process. 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 long drying time in the prior art.
[0006] To achieve at least one of the above objectives, this application provides the following technical solution:
[0007] In a first aspect, this application provides a clothes drying device, including an outer drum; an inner drum rotatably disposed inside the outer drum via a rotating shaft, the inner drum having a drying chamber capable of accommodating clothes, and a cavity between the inner drum and the outer drum being a first cavity; a drying air duct disposed outside the outer drum, the drying air duct having a return air inlet and an air outlet, the return air inlet being located on the rear wall of the outer drum and communicating with the first cavity, and the air outlet being located at the front end of the outer drum and communicating with the drying chamber; the drying air duct is configured to supply gas for drying clothes into the drying chamber and extract gas from the first cavity; a condensation tray includes: a tray body located inside the outer drum, the tray body being laid on the rear wall of the outer drum, and the tray body having a closed first channel inside;
[0008] The heat transfer medium is a liquid fluoride that can conduct heat through heat absorption and vaporization and liquefaction and heat release. The heat transfer medium is filled in the first channel and is used to exchange heat with the disk.
[0009] The rated drying capacity of the clothes drying equipment is n kg, where n is a positive number not greater than 10, and the volume of the heat transfer medium is M cm³.3 ~10+2(M-1)cm 3 , where M is an integer obtained by rounding up n / 3, and M is not greater than 3.
[0010] In the above technical solution, fluorides have a low boiling point, less than 30°C. Liquid heat transfer medium can quickly absorb heat and vaporize, while gaseous heat transfer medium can quickly dissipate heat and liquefy, thereby improving the efficiency of the condenser plate in rapidly absorbing or dissipating heat.
[0011] When the temperature of the condenser plate rises locally, the plate transfers heat to the heat transfer medium. The heat transfer medium rapidly vaporizes and absorbs heat. The vaporized heat transfer medium liquefies and releases heat in areas of the plate where the temperature is relatively low. Through the heat transfer medium, the temperature of each area of the plate can be better consistent, realizing the rapid conduction of heat from the condenser plate. This is beneficial for the rapid liquefaction of water vapor in the humid steam that comes into contact with the condenser plate.
[0012] Since different clothes drying equipment has corresponding rated drying capacity, once the rated drying capacity is determined, the corresponding volume of the heat transfer medium can be calculated using the above formula. Subsequent experimental analysis showed that, under a certain rated drying capacity, when the volume of the heat transfer medium is less than Mcm... 3 At this time, the drying time is too long and cannot meet the drying requirements of the drying equipment; the volume of the heat transfer medium is greater than 10 + 2 (m-1) cm³. 3 At the same time, increasing the volume of the heat transfer medium does not shorten the drying time or only slightly. Increasing the volume of the heat transfer medium increases product costs, but the effect is not significantly improved. By limiting the volume of the heat transfer medium within the above range, the drying equipment can achieve the need for rapid drying while reducing the cost of the condenser tray.
[0013] In some embodiments, the rated drying capacity of the clothes drying equipment is less than or equal to 3 kg, and the volume of the heat transfer medium accounts for 5% to 50% of the total volume of the first channel.
[0014] In the above technical solution, the rated drying capacity of the clothes drying equipment is less than or equal to 3 kg, and the volume of the heat transfer medium is less than 1 cm³. 3 ~10cm 3 Between these parameters, it can meet the rapid drying needs of dryer equipment while reducing the cost of condenser trays.
[0015] The volume of the heat transfer medium accounts for 5% to 50% of the total volume of the first channel. When the volume of the heat transfer medium accounts for less than 5% of the total volume of the first channel, due to the small volume of the heat transfer medium, the heat transfer medium's ability to transfer heat to various areas of the plate through vaporization is insufficient, the temperature difference between various areas of the plate is relatively large, and the dehumidification effect of the condensation plate on the humid steam is reduced.
[0016] When the volume of the heat transfer medium occupies more than 50% of the total volume of the first channel, due to the large volume of the heat transfer medium, there is insufficient space left for the heat transfer medium to vaporize in the first channel. The heat transfer medium is not easy to transfer heat to various areas of the plate through vaporization, and the temperature difference between various areas of the plate is relatively large. The dehumidification effect of the condensation plate on the humid steam is reduced.
[0017] The volume of the heat transfer medium accounts for 5% to 50% of the total volume of the first channel, ensuring that there is enough heat transfer medium to vaporize and transfer heat, and that there is enough space to accommodate the vaporized heat transfer medium, thereby improving the dehumidification effect of the condenser on the humid steam.
[0018] In some embodiments, the disk body is a sector-shaped component coaxial with the rotation axis, and the arc of the disk body is π / 2.
[0019] In the above technical solution, after the hot and humid steam flows to the plate, it flows towards the return air vent on the surface of the plate. The coaxiality between the plate and the rotating shaft helps to prolong the contact time between the hot and humid steam and the plate, facilitates heat exchange between the hot and humid steam and the condenser plate, and helps to improve the dehumidification effect of the hot and humid steam.
[0020] The larger the curvature of the condenser plate, the higher the manufacturing cost. A curvature of π / 2 helps to reduce the cost of the condenser plate while ensuring its dehumidification effect. Furthermore, the manufacturing process of the condenser plate can be reduced by cutting the circular component into four equal parts.
[0021] In some embodiments, the rated drying capacity of the clothes drying equipment is greater than 3 kg and less than or equal to 6 kg, and the volume of the heat transfer medium accounts for 10% to 60% of the total volume of the first channel.
[0022] In the above technical solution, the rated drying capacity of the clothes drying equipment is greater than 3kg and less than or equal to 6kg, and the volume of the heat transfer medium is within 2cm³. 3 ~12cm 3 Between these parameters, it can meet the rapid drying needs of dryer equipment while reducing the cost of condenser trays.
[0023] The volume of the heat transfer medium accounts for 10% to 60% of the total volume of the first channel. When the volume of the heat transfer medium accounts for less than 10% of the total volume of the first channel, due to the small volume of the heat transfer medium, the heat transfer medium's ability to transfer heat to various areas of the plate through vaporization is insufficient, the temperature difference between various areas of the plate is relatively large, and the dehumidification effect of the condensation plate on the humid steam is reduced.
[0024] When the volume of the heat transfer medium occupies more than 60% of the total volume of the first channel, due to the large volume of the heat transfer medium, there is insufficient space left for the heat transfer medium to vaporize in the first channel. The heat transfer medium is not easy to transfer heat to various areas of the plate through vaporization, and the temperature difference between various areas of the plate is relatively large. The dehumidification effect of the condensation plate on the humid steam is reduced.
[0025] The volume of the heat transfer medium accounts for 10% to 60% of the total volume of the first channel, ensuring that there is enough heat transfer medium to vaporize and transfer heat, and that there is enough space to accommodate the vaporized heat transfer medium, thereby improving the dehumidification effect of the condenser on the humid steam.
[0026] In some embodiments, the disk body is a sector-shaped component coaxial with the rotation axis, and the arc of the disk body is π.
[0027] In the above technical solution, after the hot and humid steam flows to the plate, it flows towards the return air vent on the surface of the plate. The coaxiality between the plate and the rotating shaft helps to prolong the contact time between the hot and humid steam and the plate, facilitates heat exchange between the hot and humid steam and the condenser plate, and helps to improve the dehumidification effect of the hot and humid steam.
[0028] The greater the curvature of the condenser plate, the higher its manufacturing cost. A curvature of π helps reduce the cost of the condenser plate while ensuring its dehumidification effect. Manufacturing the condenser plate by cutting the annular component into two equal parts helps reduce waste during the production process.
[0029] In some embodiments, the rated drying capacity of the clothes drying equipment is greater than 6 kg and less than or equal to 10 kg, and the volume of the heat transfer medium accounts for 15% to 70% of the total volume of the first channel.
[0030] In the above technical solution, the rated drying capacity of the clothes drying equipment is less than or equal to 6 kg, and the volume of the heat transfer medium is less than 3 cm³. 3 ~14cm 3 Between these parameters, it can meet the rapid drying needs of dryer equipment while reducing the cost of condenser trays.
[0031] The volume of the heat transfer medium accounts for 15% to 70% of the total volume of the first channel. When the volume of the heat transfer medium accounts for less than 15% of the total volume of the first channel, due to the small volume of the heat transfer medium, the heat transfer medium's ability to transfer heat to various areas of the plate through vaporization is insufficient, the temperature difference between various areas of the plate is relatively large, and the dehumidification effect of the condensation plate on humid steam is reduced.
[0032] When the volume of the heat transfer medium occupies more than 70% of the total volume of the first channel, due to the large volume of the heat transfer medium, there is insufficient space left for the heat transfer medium to vaporize in the first channel. The heat transfer medium is not easy to transfer heat to various areas of the plate through vaporization, and the temperature difference between various areas of the plate is relatively large. The dehumidification effect of the condensation plate on the humid steam is reduced.
[0033] The volume of the heat transfer medium accounts for 15% to 70% of the total volume of the first channel, ensuring that there is enough heat transfer medium to vaporize and transfer heat, and that there is enough space to accommodate the vaporized heat transfer medium, thereby improving the dehumidification effect of the condenser on the humid steam.
[0034] In some embodiments, the disk body is an annular component coaxial with the rotation axis.
[0035] In the above technical solution, after the hot and humid steam flows to the plate, it flows towards the return air vent on the surface of the plate. The coaxiality between the plate and the rotating shaft helps to prolong the contact time between the hot and humid steam and the plate, facilitates heat exchange between the hot and humid steam and the condenser plate, and helps to improve the dehumidification effect of the hot and humid steam.
[0036] Because of the large rated drying capacity, it is necessary to ensure that the hot and humid steam is in full contact with the tray as much as possible. Therefore, the tray is designed in a ring shape, which helps to improve the dehumidification effect of the condenser tray.
[0037] In some embodiments, the first channel includes a plurality of annular channels distributed from the outside to the inside along the surface of the disk.
[0038] In the above technical solution, the first channel dispersed on the plate allows the heat transfer medium to move more easily along the circumference of the plate after absorbing heat and vaporizing. The direction of heat transfer by the heat transfer medium is at an angle to the direction of flow of humid steam on the surface of the plate, which is beneficial to improving the efficiency of rapid heat absorption or dissipation of the condensation plate.
[0039] In some embodiments, the disk body includes a first plate and a second plate, which are stacked along a first direction, the first direction being the axial direction of the rotation shaft; the first plate is provided with a first protrusion along the first direction and away from the second plate; the second plate is provided with a second protrusion along the first direction and away from the first plate.
[0040] In the above technical solution, a disk body is formed by splicing a first plate and a second plate, and the first channel is formed by the surface structure of the first protrusion and the second protrusion facing each other, which can realize the setting of a closed first channel in the disk body.
[0041] In some embodiments, the wall thickness of the first plate in the region where the first protrusion is located is less than the wall thickness of the first plate in other regions not where the first protrusion is located; the wall thickness of the second plate in the region where the second protrusion is located is less than the wall thickness of the second plate in other regions not where the second protrusion is located.
[0042] In the above technical solution, the wall thickness of the first protrusion and the second protrusion constituting the first channel is relatively thin, which is beneficial to improving the heat transfer efficiency of the heat transfer medium and the plate in the first channel.

[0068] 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 long drying time of clothes drying equipment in related technologies, and obtain the technical solution of the embodiments of this application through reasonable analysis.
[0069] In related technologies, clothes drying equipment typically has two drying modes: direct venting and condenser. This application adopts the condenser drying mode. In the condenser drying mode, heated air circulates within a closed drying chamber. The water vapor carried by the air as it passes through the clothes is cooled by a condenser and discharged as liquid water, while the air is reheated and reused.
[0070] When the clothes dryer is running, the heating device is activated to heat the air to a suitable temperature. The fan blows the hot air into the inner drum of the clothes dryer, where the clothes are stored. The hot air comes into contact with the clothes, causing the moisture in the clothes to evaporate and turn into water vapor.
[0071] When the hot and humid air flows to the condenser plate, the condenser plate quickly absorbs the heat of the hot and humid air. The moisture in the hot and humid air liquefies on the condenser plate. The air with some water vapor removed continues to flow to the heating device. After the heating device heats the air, it is blown back into the inner drum. The circulating air dries the clothes.
[0072] The inner drum can be rotated during the drying process, which makes the clothes heat more evenly and avoids local overheating or overdrying. Turning the clothes over allows hot air to come into full contact with them, improving drying efficiency.
[0073] The drying system's drying sensors monitor the humidity and temperature inside the drum in real time. When the humidity sensor detects that the moisture content of the clothes has reached the set level of dryness, or when the temperature sensor detects that the drying temperature has reached the upper limit, the control system will adjust the power of the heating device and the fan speed, or directly stop the drying program.
[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] The heat exchange efficiency of the condenser plate directly affects the drying time of the clothes dryer. The higher the heat exchange efficiency of the condenser plate, the more heat is transferred between the humid air and the condenser plate when they come into contact. The more water vapor in the humid air condenses into water, and the drier the air re-enters the heating device.
[0077] The drier the air supplied to the inner drum by the heating device, the better the dehumidification effect on clothes and the shorter the dehumidification time. The heat exchange efficiency of the condenser plate in the existing technology is insufficient, and the time required to dry clothes is relatively long.
[0078] Therefore, this application provides a clothes drying device, including: an outer drum, an inner drum, a drying air duct, and a condenser tray.
[0079] The inner drum is rotatably mounted inside the outer drum via a rotating shaft. The inner drum has a drying chamber that can accommodate clothes. The cavity between the inner drum and the outer drum is the 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 on the rear wall of the outer cylinder and communicates with the first cavity. The air outlet is located at the front end of the outer cylinder and communicates with 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] The condenser plate consists of a plate body and a heat transfer medium. The plate body is located inside the outer cylinder and is laid on the rear wall of the outer cylinder. The interior of the plate body has a closed first channel.
[0083] The heat transfer medium is a liquid fluoride that can conduct heat through heat absorption and vaporization, liquefaction and heat release. The heat transfer medium is filled in the first channel and is used to exchange heat with the plate.
[0084] The rated drying capacity of the clothes dryer is n kg, where n is a positive number not greater than 10, and the volume of the heat transfer medium is M cm³. 3 ~10+2(M-1)cm 3 , where M is an integer obtained by rounding up n / 3, and M is not greater than 3.
[0085] 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.

[0087] Figure 1A 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, inner drum 4, and 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 1 as well as Figure 2 For ease of explanation, we define a first direction, a second direction, and a vertical direction. The first direction is the depth direction of the drying equipment, which is also the axis of rotation of the inner drum 4 and the axis of rotation of the shaft connected to the inner drum 4. The second direction is the width direction of the drying equipment, and the third direction is the vertical direction when the drying equipment is in normal use and placement.
[0092] 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.
[0093] 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.
[0094] 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.
[0095] Reference Figure 2In 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.
[0096] 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.
[0097] 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.
[0098] 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 .
[0099] 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.
[0100] 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.
[0101] 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.
[0102] 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.
[0103] 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.
[0104] 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.
[0105] 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.
[0106] 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.
[0107] 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.
[0108] 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.
[0109] Specifically, high-temperature air from the drying duct 5 enters the drying chamber 41, heating the clothes inside and removing moisture from them, creating humid air. This humid air enters the first chamber 23 through the through-hole 43 on the inner cylinder 4 and flows over the condenser plate 6 on the rear end wall 21. The humid air contacts the condenser plate 6 for heat exchange, causing the moisture in the humid air to condense on the condenser plate 6. The air, after being condensed and dehumidified by the condenser plate 6, re-enters the drying duct 5 through the return air vent and is reheated, thus realizing the drying cycle of the drying equipment. After multiple cycles, the clothes are dried.
[0110] The shape of the condenser plate 6 corresponds to the shape of the rear end wall 21 facing the inner cylinder 4 along the first direction, which allows the condenser plate 6 to occupy less space inside the outer cylinder 2. The condenser plate 6 is laid on the rear end wall 21 of the outer cylinder 2. The condenser plate 6 is a ring-shaped component with a notch in the middle to accommodate the rotation shaft 42.
[0111] 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.
[0112] Reference Figure 5An inlet 24 can be provided on the rear end 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 coolant transported by the inlet pipe into the inner cavity of the outer cylinder 2, and exchange heat with the condenser 6 to cool the condenser 6. After the coolant flows through the condenser and is cooled, it is discharged through the drain 25.
[0113] Optionally, the liquid inlet 24 can be located at the top of the condenser plate 6, so that the coolant can fall from the top of the condenser plate 6 to the bottom of the condenser plate 6 by its own gravity. During this process, there is a larger heat exchange area between the coolant and the condenser plate 6, which can improve the condensation efficiency of the condenser plate 6.
[0114] It should be noted that the coolant can also directly exchange heat with the hot and humid air inside the outer cylinder 2, condensing and dehumidifying the hot and humid air.
[0115] For example, the coolant is municipal tap water. In another embodiment, the coolant is other liquids, such as a mixture of superabsorbent polymer, carboxymethyl cellulose, and water.
[0116] In another embodiment, other existing cooling methods can be used to cool the condenser plate 6, such as using a fan to blow air onto the condenser plate 6 for cooling.
[0117] Figures 7-10 The diagram shows the structure of the condenser plate in different states.
[0118] Reference Figure 7 as well as Figure 8 The condenser plate 6 includes a plate body 61 and a heat transfer medium. The plate body 61 is located inside the outer cylinder 2 and is laid on the rear wall of the outer cylinder 2. The interior of the plate body 61 has a closed first channel 62. The heat transfer medium is filled in the first channel 62 and is used to exchange heat with the plate body 61.
[0119] Specifically, the disk 61 has high heat conduction efficiency, and optionally, the disk 61 is made of metal. For example, the disk 61 is made of stainless steel or aluminum alloy.
[0120] The heat transfer medium is located inside the disk 61 and can flow in the first channel 62. When the local temperature of the disk 61 rises, heat exchange occurs between that area of the disk 61 and the heat transfer medium. The heat transfer medium in that area vaporizes as its temperature rises. The vaporized heat transfer medium quickly moves to other areas of the disk 61 and liquefies again in those other areas, releasing heat and transferring the heat it carries to those other areas. This achieves rapid heat transfer on the disk 61 and improves the heat conduction efficiency of the disk 61.
[0121] By utilizing the high heat exchange efficiency of the disc 61, the hot and humid air is cooled by passing through the metal disc 61, which can achieve a better dehumidification effect. This can improve the heat exchange efficiency with the air, thereby improving the condensation efficiency of the drying equipment and shortening the drying time.
[0122] The cross-sectional shape of the first channel 62 is not limited. For example, the cross-sectional shape of the first channel 62 is circular. Optionally, the cross-sectional shape of the first channel 62 is semi-elliptical or semi-circular.
[0123] In this embodiment, the cross-section of the first channel 62 is the same at all positions. In another embodiment, the cross-section of the first channel 62 differs at different positions.
[0124] Reference Figure 7 as well as Figure 8 The first channel 62 includes multiple annular channels distributed from the outside to the inside along the surface of the disk 61. The multiple annular channels are interconnected. For example, the first channel 62 also includes multiple radial channels that connect the multiple annular channels.
[0125] In another embodiment, the first channel 62 is arranged in a spiral shape from the inside out. In another embodiment, the first channel 62 is arranged in a grid pattern.
[0126] The heat transfer medium is a liquid fluoride, including at least one of trichlorofluoromethane, dichlorodifluoromethane, perfluorodimethylcyclohexane, and perfluoronaphthene. The heat transfer medium has a boiling point below 20°C and exhibits high heat dissipation capacity and heat exchange efficiency.
[0127] The temperature of the humid air in the clothes drying equipment is between 20 and 65°C, and the above-mentioned heat transfer media all meet the requirements for the use of the condenser plate 6.
[0128] The rated drying capacity of the clothes drying equipment is n kg, where n is a positive number not greater than 10, and the volume of the heat transfer medium is M cm³. 3 ~10+2(M-1)cm 3 , where M is an integer obtained by rounding up n / 3, and M is not greater than 3.
[0129] Explanation is provided for dryers with a rated drying capacity of 3 kg or less.
[0130] When the rated drying capacity of a clothes dryer is less than or equal to 3 kg (e.g., when the rated drying capacity is 1 kg, 1.5 kg, 2 kg, 2.5 kg, 2.8 kg, or 3 kg), M is 1. The volume of the heat transfer medium is within 1 cm³. 3 ~10cm 3 between.
[0131] In this embodiment, the cross-sectional area of the first channel 62 is 5mm². 2 The total volume of the first channel 62 is 20000 mm². 3 =0.02dm 3 Taking this as an example, the volume of the heat transfer medium at this time accounts for 5% to 50% of the total volume of the first channel 62.
[0132] For ease of description, the filling amount is defined as the volume of the heat transfer medium occupying 62% of the total volume of the first channel.
[0133] By repeatedly changing the volume of the heat transfer medium, the corresponding filling amount was calculated, and the actual drying time of the clothes drying equipment was obtained. The following tests were conducted for different volumes of heat transfer medium:
[0134] The volume of the heat transfer medium is 0.6 cm³. 3 At that time, the filling amount of the heat transfer medium was 3%, and the drying time was controlled between 60 and 330 minutes.
[0135] The volume of the heat transfer medium is 0.8 cm³. 3 At that time, the filling amount of the heat transfer medium was 4%, and the drying time was controlled between 57 and 227 minutes.
[0136] The volume of the heat transfer medium is 1 cm³. 3 When the heat transfer medium is filled with 5%, the drying time is controlled between 55 and 225 minutes.
[0137] The volume of the heat transfer medium is 3 cm³. 3 At that time, the filling amount of the heat transfer medium was 15%, and the drying time was controlled between 50 and 220 minutes.
[0138] The volume of the heat transfer medium is 5 cm³. 3 At that time, the filling amount of the heat transfer medium was 25%, and the drying time was controlled between 45 and 215 minutes.
[0139] The volume of the heat transfer medium is 7 cm³. 3 At that time, the filling amount of the heat transfer medium was 35%, and the drying time was controlled between 40 and 210 minutes.
[0140] The volume of the heat transfer medium is 10 cm³. 3 At that time, the filling amount of the heat transfer medium was 50%, and the drying time was controlled between 35 and 205 minutes.
[0141] The volume of the heat transfer medium is 10.2 cm³. 3 At that time, the filling amount of the heat transfer medium was 51%, and the drying time was controlled between 35 and 205 minutes.
[0142] The volume of the heat transfer medium is 10.6 cm³. 3At that time, the filling amount of the heat transfer medium was 53%, and the drying time was controlled between 33 and 203 minutes.
[0143] The volume of the heat transfer medium is 11 cm³. 3 At that time, the filling amount of the heat transfer medium was 55%, and the drying time was controlled between 30 and 200 minutes.
[0144] The above experiments show that when the filling amount of the heat transfer medium is less than 1 cm³, 3 When the heat transfer medium content is less than 5%, the drying time of the clothes dryer is relatively long; increasing the proportion of heat transfer medium significantly shortens the drying time of the clothes dryer.
[0145] When the filling amount of the heat transfer medium is greater than 10 cm³ 3 At this point, the heat transfer medium filling amount is greater than 50%, and the drying time of the dryer can meet the needs of rapid drying; however, increasing the proportion of heat transfer medium does not significantly shorten the drying time of the dryer.
[0146] For clothes drying equipment with a rated drying capacity of 3 kg or less, control the filling amount of heat transfer medium in the condenser tray 6 to ensure that the volume of the heat transfer medium is within 1 cm³. 3 ~10cm 3 The range not only meets the rapid drying needs of the drying equipment, but also controls the amount of heat transfer medium used, reducing the cost of the heat transfer medium and lowering the cost of the condenser plate 6.
[0147] The disk 61 is a fan-shaped component, and the radius of the disk 61 is π / 2.
[0148] By controlling the curvature of the condenser tray 6 so that the curvature of the tray body 61 is π / 2, the rapid drying needs of dryers with a rated drying capacity of less than or equal to 3kg are met, while the size of the condenser tray 6 is reduced, thus reducing the cost of the condenser tray 6.
[0149] Reference Figure 8 , Figure 8 Only the overall schematic diagram of the first plate 63 and the second plate 64 is shown. The position, size and connection method of the first channel 62 are for illustrative purposes only.
[0150] The disc body 61 includes a first plate 63 and a second plate 64, which are stacked along a first direction. The first plate 63 is provided with a first protrusion along the first direction and away from the direction of the second plate 64, and the second plate 64 is provided with a second protrusion along the first direction and away from the direction of the first plate 63.
[0151] The first plate 63 and the second plate 64 are formed by stamping the semi-circular plate with a mold to form a recess corresponding to the position of the first channel 62. Finally, the first plate 63 and the second plate 64 are stacked and welded along the thickness direction to form the first channel 62 enclosed in the disc body 61.
[0152] In this embodiment, the first channel 62 has a double-sided bulging shape. The wall thickness of the first plate 63 in the region where the first protrusion is located is less than the wall thickness of the first plate 63 in the region where the first protrusion is not located. The wall thickness of the second plate 64 in the region where the second protrusion is located is less than the wall thickness of the second plate 64 in the region where the second protrusion is not located.
[0153] The thinness of the area of the first channel 62 formed by the first plate 63 and the second plate 64 is beneficial to reducing the heat transfer path between the first plate 63 and the second plate 64 and the heat transfer medium, thereby improving the heat transfer efficiency between the first plate 63 and the second plate 64 and the heat transfer medium.
[0154] In another embodiment, the wall thickness of the first plate 63 is substantially the same at all locations, and the wall thickness of the second plate 64 is substantially the same at all locations.
[0155] In another embodiment, reference is made to... Figure 9 The pipeline is in a single-sided expansion shape. The wall thickness of the first plate 63 in the region where the first protrusion is located is less than the wall thickness of the first plate 63 in the region where the first protrusion is not located.
[0156] In another embodiment, the conduit is in a one-sided expansion shape. The wall thickness of the second plate 64 in the region where the second protrusion is located is less than the wall thickness of the second plate 64 in the region where the second protrusion is not located.
[0157] The thickness of the condenser plate 6 is set along the first direction. When the humid and hot air in the first cavity 23 flows through the condenser plate 6, the contact area between the air and the condenser plate 6 is large, which is beneficial to the heat transfer between the humid and hot air and the condenser plate 6.

[0161] In this embodiment, the cross-sectional area of the first channel 62 is 5mm². 2The total volume of the first channel 62 is 20000 mm². 3 =0.02dm 3 Taking this as an example, the volume of the heat transfer medium at this time accounts for 10% to 60% of the total volume of the first channel 62.
[0162] By repeatedly changing the volume of the heat transfer medium, the corresponding filling amount was calculated, and the actual drying time of the clothes drying equipment was obtained. The following tests were conducted for different volumes of heat transfer medium:
[0163] The volume of the working fluid is 1.6 cm³. 3 At that time, the filling amount of the heat transfer medium was 8%, and the drying time was controlled between 95 and 335 minutes.

[0169] The volume of the working fluid is 10 cm³. 3 At that time, the filling amount of the heat transfer medium was 50%, and the drying time was controlled between 70 and 310 minutes.
[0170] The volume of the working fluid is 12 cm³. 3 At that time, the filling amount of the heat transfer medium was 60%, and the drying time was controlled between 65 and 305 minutes.
[0171] The volume of the working fluid is 12.2 cm³. 3 At that time, the filling amount of the heat transfer medium was 61%, and the drying time was controlled between 65 and 305 minutes.
[0172] The volume of the working fluid is 12.6 cm³. 3 At that time, the filling amount of the heat transfer medium was 63%, and the drying time was controlled between 63 and 303 minutes.
[0173] The volume of the working fluid is 13 cm³. 3 At that time, the filling amount of the heat transfer medium was 65%, and the drying time was controlled between 60 and 300 minutes.
[0174] The above tests show that for clothes drying equipment with a rated drying capacity greater than 3kg and less than or equal to 6kg, when the filling amount of the heat transfer medium is less than 2cm... 3 When the heat transfer medium content is less than 10%, the drying time of the clothes dryer is relatively long; by increasing the proportion of heat transfer medium, the drying time of the clothes dryer is significantly shortened.
[0175] When the filling amount of the heat transfer medium is greater than 12cm 3 At this point, the heat transfer medium filling amount is greater than 60%, and the drying time of the dryer can meet the needs of rapid drying; however, increasing the proportion of heat transfer medium does not significantly shorten the drying time of the dryer.
[0176] For clothes dryers with a rated drying capacity greater than 3kg and less than or equal to 6kg, control the filling amount of heat transfer medium in the condenser tray 6 to ensure that the volume of the heat transfer medium is within 2cm³. 3 ~12cm 3 The range not only meets the rapid drying needs of the drying equipment, but also controls the amount of heat transfer medium used, reducing the cost of the heat transfer medium and lowering the cost of the condenser plate 6.
[0177] Reference Figure 7 The disk 61 is a fan-shaped component, and the curvature of the disk 61 is π.
[0178] By controlling the curvature of the condenser tray 6 so that the curvature of the tray body 61 is π, the rapid drying needs of dryers with a rated drying capacity greater than 3kg and less than or equal to 10kg are met, while the size of the condenser tray 6 is reduced, thus reducing the cost of the condenser tray 6.

[0198] For clothes drying equipment with a rated drying capacity greater than 6 kg and less than or equal to 10 kg, control the filling amount of heat transfer medium in the condenser tray 6 to ensure that the volume of the heat transfer medium is within 3 cm³. 3 ~14cm 3 The range not only meets the rapid drying needs of the drying equipment, but also controls the amount of heat transfer medium used, reducing the cost of the heat transfer medium and lowering the cost of the condenser plate 6.
