Description

Technical Field

[0001] This application relates to the field of clothes drying equipment technology, and more particularly to a clothes dryer. Background Technology

[0002] As people's living standards improve, clothes dryers are becoming increasingly popular. A clothes dryer generally consists of a cabinet, a drum, and a heating element, with the heating element and drum located inside the cabinet. When the dryer is working, the drum rotates, causing the clothes to rotate. Air heated by the heating element is blown into the drum, and the clothes are dried by the hot air.

[0003] In related technologies, the drum has a large volume. When drying a small amount of clothing, especially a single garment, the drop height of the clothing is low, and the contact area between the clothing and the hot air is small, resulting in a longer drying time, low drying efficiency, and poor economic performance. Utility Model Content

[0004] This application provides a clothes dryer to solve the problem of low efficiency when drying single garments.

[0005] A clothes dryer, comprising:

[0006] The box body has an internal cavity for receiving the contents;

[0007] A door, which is rotatably connected to the housing to open or close the receiving cavity;

[0008] A roller is rotatably disposed within the receiving cavity, and a drying chamber is formed inside the roller. An air inlet is provided on the bottom wall of the drying chamber, and an air outlet is provided in the drying chamber. The drying chamber is configured such that when drying clothes, the gas in the drying chamber flows from the air inlet toward the air outlet in a first direction.

[0009] A drying air duct is installed inside the chamber and located outside the drum. One end of the drying air duct is connected to the air inlet and is used to introduce hot air into the drying chamber.

[0010] At least two fasteners are spaced apart on the inner peripheral wall of the drying chamber. The at least two fasteners are used to clamp different parts of the clothing, so that the clothing is unfolded in the drying chamber. The plane on which the clothing is unfolded intersects with the first direction.

[0011] The above-mentioned technical features have at least the following technical effects:

[0012] By using at least two fixing members to clamp different parts of the garment, it is kept fully extended. Because the extended garment intersects with the first direction, it is placed horizontally within the drying chamber. This results in a significantly greater gas pressure difference between the windward and leeward sides of the garment compared to when it is not horizontal. Since the pressure is low in areas of high flow velocity and high in areas of low flow velocity, the horizontally placed garment experiences a greater difference in flow velocity due to its shape and position within the drying chamber, creating a stronger pressure gradient. This pressure difference drives the airflow at high speed through the gaps between the garment fibers. Compared to randomly stacked garments, the horizontal arrangement reduces flow resistance, allowing air to penetrate the fiber layer more efficiently and accelerating moisture removal. Furthermore, the rate of moisture evaporation is positively correlated with gas flow velocity. High-speed airflow can more quickly remove saturated water vapor molecules from the fiber surface, maintaining a larger concentration gradient and continuously driving evaporation. This, in turn, improves the drying efficiency of a single garment, enhancing the economy of the dryer when drying a single item.

[0013] In one exemplary embodiment of this disclosure, the fastener includes:

[0014] The fixing part is disposed on the inner peripheral wall of the drying chamber;

[0015] A pressing part is provided on the side of the fixing part away from the inner peripheral wall of the drying chamber, and the pressing part is detachably connected to the fixing part;

[0016] When the pressing part is connected to the fixing part, the pressing part and the fixing part remain relatively fixed to form a clamping space between the pressing part and the fixing part to clamp the garment.

[0017] When the pressing part and the fixing part separate, the pressing part can move away from the fixing part to release the clamping of the garment.

[0018] The above-mentioned technical features have at least the following technical effects:

[0019] The fastener comprises a fixing part and a pressing part, which are detachably connected. When connected, clothing is placed between the two parts and clamped. This facilitates assembling the clothing and fastener together outside the dryer, and then installing the entire assembly into the drying chamber. After drying, the pressing part is detached from the fixing part to release the clamp on the clothing, allowing for easy removal. The fastener's simple structure enables quick clamping and detachment of clothing, making it convenient for users.

[0020] In one exemplary embodiment of this disclosure, the pressing part and the fixing part are connected by magnetic attraction.

[0021] The above-mentioned technical features have at least the following technical effects:

[0022] The pressing part and the fixing part are connected by magnetic attraction, making it easier to clamp clothes. Simply place the clothes on the fixing part first, and then magnetically attach the pressing part to the fixing part to clamp the clothes. The clothes are clamped by magnetic attraction, which is convenient for users.

[0023] In one exemplary embodiment of this disclosure, the fastener further includes a first magnetic element and a second magnetic element;

[0024] The fixing part is provided with a first cavity for accommodating the first magnetic component, the first magnetic component is housed in the first cavity, and the fixing part is magnetically connected to the inner peripheral wall of the drying chamber through the first magnetic component.

[0025] The pressing part has a second cavity for accommodating the second magnetic component. The second magnetic component is housed in the second cavity. The pressing part is magnetically connected to the fixing part by the magnetic attraction between the second magnetic component and the first magnetic component.

[0026] The above-mentioned technical features have at least the following technical effects:

[0027] By forming a first cavity to house the first magnetic component and a second cavity to house the second magnetic component, the first and second magnetic components are covered by the fixing part and the pressing part, preventing them from being exposed. Simultaneously, by providing the first and second magnetic components, the fixing part and the pressing part are connected by their magnetic attraction, achieving a detachable connection and facilitating user operation of the fixing component and clothing.

[0028] In one exemplary embodiment of this disclosure, the side of the fixing part facing the pressing part forms a first pressing surface, and the side of the pressing part facing the fixing part forms a second pressing surface. The second pressing surface has at least two spaced first abutments protruding toward the first pressing surface. When the pressing part is connected to the fixing part, the clamping space is formed between the first abutments and the first pressing surface, and the clothing is clamped between the first pressing surface and the first abutments.

[0029] The above-mentioned technical features have at least the following technical effects:

[0030] By setting a first abutment to abut against one side of the garment, the garment is clamped between the first pressing surface and the first abutment, reducing the contact area between the garment and the pressing part. The side of the garment opposite to the second pressing surface is easier for water to flow out, making the garment easier to dry.

[0031] In one exemplary embodiment of this disclosure, the first pressing surface has at least two spaced second abutments protruding toward the second pressing surface, the at least two second abutments corresponding one-to-one with the at least two first abutments. When the pressing part is connected to the fixing part, the clamping space is formed between the first abutments and the second abutments, and the clothing is clamped between the first abutments and the second abutments.

[0032] The above-mentioned technical features have at least the following technical effects:

[0033] By forming a second abutment on the first pressing surface, the clamping space is formed between the first and second abutments when the pressing part and the fixing part are connected. The garment is clamped between the first and second abutments, further reducing the contact area between the garment and the fixing part. The two sides of the garment only contact the first and second abutments. The part of the garment located between the pressing part and the fixing part is suspended except for the part that contacts the first and second abutments, thereby facilitating the evaporation of moisture from the clamped part of the garment as much as possible. The clamped part of the garment is easier to dry, avoiding uneven drying of the garment after drying.

[0034] In one exemplary embodiment of this disclosure, the at least two first abutments are located at the edge of the projection of the first magnetic element onto the second abutment surface.

[0035] The above-mentioned technical features have at least the following technical effects:

[0036] With the above arrangement, the first abutment and the second magnetic component are staggered, and the first abutment does not affect the magnetic attraction between the first magnetic component and the second magnetic component, so that the clothing can be clamped by the pressing part and the fixing part as much as possible.

[0037] In one exemplary embodiment of this disclosure, the at least two fasteners are evenly spaced along the circumferential distance of the drying chamber, and the plane containing the at least two fasteners is perpendicular to the first direction.

[0038] The above-mentioned technical features have at least the following technical effects:

[0039] The above setup allows the clothing to unfold to a larger area after being clamped by the fasteners, and the hot air entering from the air inlet can be blown directly onto the windward side of the clothing, accelerating the evaporation of moisture from the clothing.

[0040] In one exemplary embodiment of this disclosure, the at least two fasteners are disposed on the inner peripheral wall of the drying chamber near the air inlet.

[0041] The above-mentioned technical features have at least the following technical effects:

[0042] Because the temperature gradually decreases from the air inlet to the air outlet inside the drying chamber, the clothes are warmer near the air inlet than in other areas, allowing the hot air entering the drying chamber from the air inlet to flow to the clothes as quickly as possible, thus accelerating the drying process.

[0043] In one exemplary embodiment of this disclosure, the dryer further includes a drain trough, a drain pump, and a water container. The drain trough is disposed on the side of the drying air duct, and the drying air duct is provided with a drain hole communicating with the drain trough. The drain pump is disposed in the housing, with its inlet end communicating with the drain trough and its outlet end communicating with the water container. The water container is disposed in the housing and located on top of the drum.

[0044] The above-mentioned technical features have at least the following technical effects:

[0045] By setting up a drain trough, a drain pump, and a water container, the condensate generated during the drying process can be drained through the drain trough and the drain pump and finally enter the water container. This allows users to clean the condensate through the water container, preventing the condensate from having nowhere to go and ensuring that the dryer can work continuously to dry the clothes.

[0046] Beneficial effects:

[0047] In this application, by setting at least two fixing members to clamp different parts of the clothing, the clothing is kept unfolded. Because the unfolded clothing intersects with the first direction, it is placed horizontally in the drying chamber, resulting in a much greater gas pressure difference between the windward and leeward sides of the clothing than when the clothing is not horizontally placed. Since the pressure is low in areas with high flow velocity and high in areas with low flow velocity, the horizontally placed clothing in the drying chamber has a greater difference in flow velocity on both sides due to its shape and position, thus generating a stronger pressure gradient. The pressure difference drives the airflow to pass through the gaps between the clothing fibers at high speed. Compared with randomly stacked clothing, the horizontal position reduces flow resistance, allowing air to penetrate the fiber layer more efficiently and accelerating moisture removal.

[0048] In addition, the rate of moisture evaporation is positively correlated with the gas flow rate. High-speed airflow can carry away saturated water vapor molecules on the fiber surface more quickly, maintain a larger concentration gradient, and thus continuously promote evaporation, thereby improving the drying efficiency of a single garment and increasing the economy of the dryer when drying a single garment.

Detailed Implementation

[0055] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0056] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0057] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0058] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0059] In related technologies, the drum has a large volume. When drying a small amount of clothing, especially a single garment, the clothes fall from a low height, resulting in a small contact area between the clothes and the hot air. This leads to a longer drying time, lower drying efficiency, and poor economic performance. To address this problem, this application proposes a clothes dryer.

[0060] For ease of understanding, the side of the dryer facing the user for operation is called the front side of the dryer, and the side of the dryer facing away from the user is called the back side.

[0061] See Figure 1 A clothes dryer is used to dry clothes. The clothes dryer may include a housing 1. The interior of the housing 1 has a receiving cavity for accommodating other components of the clothes dryer, and an opening is provided on the front side wall of the housing 1, which communicates with the receiving cavity.

[0062] In some embodiments, the dryer may include a door 2. The door 2 is rotatably connected to the housing 1, for example, the door 2 may be rotatably connected to the front side wall of the housing 1 to open or close the receiving cavity. Thus, when the user uses the dryer to dry clothes, they can open the door 2 to put the clothes to be dried into the drum 5 set in the receiving cavity for drying. After putting them in, the receiving cavity can be closed by closing the door 2 so that the dryer can start running.

[0063] In some embodiments, the dryer may include a drum 5, which extends in a front-to-back direction to form a cylindrical structure with one end open. The drum 5 is rotatably disposed within a receiving cavity, and a drying chamber 50 is formed inside the drum 5. One end of the drying chamber 50 is open and faces the door 2. The drying chamber 50 is used to hold clothes to be dried, and hot air circulates within the drying chamber 50 to dry the clothes. When a user uses the dryer, the clothes can be placed into the drying chamber 50 for drying.

[0064] In some embodiments, the bottom wall of the drying chamber 50 is provided with an air inlet 51 and an air outlet 52. The drying chamber 50 is configured such that, during the drying of clothes, the gas inside the drying chamber 50 flows from the air inlet 51 toward the air outlet 52 in a first direction. The air outlet 52 may be opposite to the air inlet 51 and located at the front end of the drum 5, while the air inlet 51 is located at the rear end of the drum 5. The first direction may be the axial direction of the drum 5.

[0065] In some embodiments, the dryer may include a drive unit 6, a heat pump assembly 7, and a fan 9. The drive unit 6 may include a motor 60 and a belt 61 disposed in the housing 1. The output end of the motor 60 is connected to the roller 5 via the belt 61 to drive the roller 5 to rotate.

[0066] In some embodiments, the dryer may include a drying duct 3, which is disposed inside the housing 1 and outside the drum 5. One end of the drying duct 3 is connected to the air inlet 51 for introducing hot air into the drying chamber 50, and the other end of the drying duct 3 is connected to the air outlet 52. The high-humidity air formed after drying clothes flows back into the drying duct 3 from the air outlet 52, thereby continuously circulating and drying the clothes in the drying chamber 50. The drying duct 3 may include a front air duct 30, a bottom air duct 31, and a rear air duct 32. The bottom air duct 31 is disposed at the bottom of the drum 5 and extends in the front-to-back direction. One end of the front air duct 30 is connected to the front end of the bottom air duct 31, and the other end is connected to the air outlet 52. One end of the rear air duct 32 is connected to the rear end of the bottom air duct 31, and the other end is connected to the air inlet 51. The air circulates in the drying duct 3 and the drying chamber 50 to continuously dry the clothes.

[0067] In some embodiments, the heat pump assembly 7 includes an evaporator 70, a condenser 71, and a compressor disposed within the bottom air duct 31. When the dryer is operating, the surface of the condenser 71 is at a high temperature, while the surface of the evaporator 70 is at a low temperature. The compressor converts electrical energy into heat energy in the refrigerant within the heat pump assembly 7. This heat energy is transferred to the circulating gas through heat exchange. After a certain period of circulation, the gas entering the drying chamber 50 becomes high-temperature air. The moisture in the clothes within the drying chamber 50 evaporates under the heating of the high-temperature air, forming high-temperature, high-humidity gas, thereby removing the moisture from the clothes and drying them. The drying principle of the heat pump assembly 7 can be referenced from existing dryers and will not be elaborated further here.

[0068] In some embodiments, the dryer may further include a drainage assembly 8. The drainage assembly 8 includes a drainage trough 80, a drainage pump 81, and a water container 82. The drainage trough 80 is disposed on the bottom side of the drying air duct 3, and the drying air duct 3 is provided with a drainage hole communicating with the drainage trough 80. Specifically, the drainage trough 80 is disposed on the bottom side of the bottom air duct 31. The gas flowing through the evaporator 70 with a low surface temperature will condense into water, and the condensate will enter the drainage trough 80 through the drainage hole for temporary storage.

[0069] In some embodiments, the drain pump 81 is disposed inside the housing 1 and outside the drum 5. The inlet end of the drain pump 81 is connected to the drain trough 80, and the outlet end of the drain pump 81 is connected to the water container 82. The water container 82 is disposed inside the housing 1 and located at the top of the drum 5. The condenser 71 temporarily stored in the drain trough 80 is pumped to the water container 82 by the drain pump 81. The user can remove the water container 82 to clean the condensate water, and finally complete the drying of the clothes.

[0070] In some embodiments, the fan 9 is disposed inside the housing 1 and located behind the drum 5. The fan blades of the fan 9 extend into the rear air duct 32 to accelerate the entry of the gas in the drying air duct 3 into the drying chamber 50 and to promote the circulation of gas in the drying air duct 3 and the drying chamber 50, thereby accelerating the drying of clothes.

[0071] See also Figures 2 to 4 In some embodiments, the dryer may include at least two fixing members 4, which are spaced apart on the inner peripheral wall of the drying chamber 50. The at least two fixing members 4 are used to clamp different parts of the clothing, causing the clothing to unfold within the drying chamber 50, with the unfolded plane intersecting the first direction. By clamping different parts of the clothing, such as the top and bottom, with at least two fixing members 4, the clothing is kept unfolded. Because the unfolded clothing intersects the first direction, it is placed horizontally within the drying chamber 50, resulting in a much greater gas pressure difference between the windward and leeward sides of the clothing compared to when the clothing is not horizontal.

[0072] Because areas with high flow rates have low pressure, while areas with slow flow rates have high pressure, clothes placed horizontally within the drying chamber 50 experience a greater difference in flow rate on both sides due to their shape and position within the airflow. This creates a stronger pressure gradient. This pressure difference drives the airflow at high speed through the gaps between the clothing fibers. Compared to randomly stacked clothes, the horizontal arrangement reduces flow resistance, allowing air to penetrate the fiber layer more efficiently and accelerating moisture removal. Furthermore, the rate of moisture evaporation is positively correlated with gas flow rate. High-speed airflow can more quickly remove saturated water vapor molecules from the fiber surface, maintaining a larger concentration gradient (i.e., the partial pressure difference of water vapor between the fiber surface and the air), thereby continuously promoting evaporation and improving the drying efficiency of individual garments.

[0073] In some embodiments, at least two fasteners 4 are evenly spaced along the circumference of the drying chamber 50, and the plane containing the at least two fasteners 4 is perpendicular to the first direction. This allows the clothes to unfold more after being clamped by the fasteners 4, enabling the hot air entering from the air inlet 51 to directly blow onto the windward side of the clothes, thus accelerating the evaporation of moisture from the clothes. In this embodiment, two fasteners 4 are provided, evenly spaced along the circumference of the drying chamber 50. One fastener is located at the top of the inner circumferential wall of the drying chamber 50, and the other is located at the bottom of the inner circumferential wall of the drying chamber 50, which can be used to clamp the top and bottom of the clothes respectively. Of course, three, four, or more fasteners 4 can also be provided to clamp different parts of the clothes, making the clothes more flexible.

[0074] In some embodiments, the planes where at least two fasteners 4 are located may also have a certain acute angle with the first direction, so that the clothes are tilted and unfolded in the drying chamber 50.

[0075] In some embodiments, at least two fixing members 4 are disposed on the inner peripheral wall of the drying chamber 50 near the air inlet 51, so that the hot air entering the drying chamber 50 from the air inlet 51 can flow to the clothes as quickly as possible. Since the temperature gradually decreases from the air inlet 51 to the air outlet 52 within the drying chamber 50, the clothes near the air inlet 51 are at a higher temperature than other locations, thereby accelerating the drying process. It should be noted that "fixing member 4 near the air inlet 51" means that the fixing member 4 is closer to the air inlet 51 than to the air outlet 52.

[0076] In some embodiments, the fastener 4 may include a fastening portion 40 disposed on the inner peripheral wall of the drying chamber 50. The fastening portion 40 can be fixed to the inner peripheral wall of the drying chamber 50, ensuring it remains installed within the drying chamber 50. Alternatively, the fastening portion 40 can be detachably connected to the inner peripheral wall of the drying chamber 50. When drying a single garment, the fastening portion 40 is installed on the inner peripheral wall of the drying chamber 50, and the fastening portion 40 is provided as needed. The fastening portion 40 can be a plate-like structure or a block-like structure; there is no limitation thereto.

[0077] In some embodiments, the fixing member 4 may include a pressing part 41, which is disposed on the side of the fixing part 40 away from the inner peripheral wall of the drying chamber 50. The pressing part 41 is detachably connected to the fixing part 40. When the pressing part 41 is connected to the fixing part 40, the pressing part 41 and the fixing part 40 remain relatively fixed to form a clamping space for clamping clothes between the pressing part 41 and the fixing part 40. During drying, a portion of the clothes can be clamped between the pressing part 41 and the fixing part 40 outside the dryer, and then the fixing member 4 and the clothes can be installed into the drying chamber 50 as a whole, which is convenient for users to clamp the clothes. When the pressing part 41 and the fixing part 40 are separated, the pressing part 41 can move away from the fixing part 40 to release the clamping of the clothes. After drying, the pressing part 41 can be separated from the fixing part 40 first, and the clothes will be naturally released from clamping, which makes it easy to take the clothes out of the drying chamber 50.

[0078] In some embodiments, when assembling the fastener 4, the pressing part 41 may be disposed opposite to the fixing part 40, with their opposing sides close together to clamp the clothing. The pressing part 41 may be a plate-like structure or a block-like structure, corresponding to the structure of the fixing part 40.

[0079] In some embodiments, the pressing part 41 and the fixing part 40 are magnetically connected, thereby achieving a detachable connection between them. When it is necessary to clamp clothing, a portion of the clothing is first attached to the fixing part 40, and then the pressing part 41 is brought close to the fixing part 40. The two are magnetically connected to clamp the clothing between them. After drying, the user can manually remove the pressing part 41 from the fixing part 40 to release the clamping of the clothing.

[0080] In some embodiments, the pressing part 41 and the fixing part 40 can also be connected by bolts, enabling a detachable connection between them. For example, both the fixing part 40 and the pressing part 41 have corresponding screw holes at positions away from the clothing. When clamping the clothing, one side of the clothing is first placed on the fixing part 40, and then the pressing part 41 is pressed onto the other side of the clothing. The user applies force to press the clothing tightly, and then bolts are inserted into the corresponding screw holes. By tightening the bolts, the pressing part 41 and the fixing part 40 clamp the clothing. After drying, the bolts are unscrewed to release the clamping of the clothing.

[0081] In some embodiments, the fixing member 4 may include a first magnetic member 42. The fixing part 40 has a first cavity for accommodating the first magnetic member 42, which is housed within the first cavity, making the fixing part 40 itself magnetic. Thus, since the roller 5 is made of metal and is magnetic, the fixing part 40 can be magnetically attracted to the inner peripheral wall of the drying chamber 50 by the first magnetic member 42, achieving a detachable connection between the fixing part 40 and the drying chamber 50. The fixing part 40 itself can be a plastic shell with a hollow interior to form the aforementioned first cavity, without affecting the magnetism of the first magnetic member 42.

[0082] In some embodiments, the fixing member 4 may include a second magnetic member 43. The pressing portion 41 has a second cavity for accommodating the second magnetic member 43, which is housed within the second cavity, making the pressing portion 41 magnetic. Thus, when clothing is clamped, the pressing portion 41 is magnetically connected to the fixing portion 40 through the magnetic attraction between the second magnetic member 43 and the first magnetic member 42. By making the first magnetic member 42 and the second magnetic member 43 strongly magnetic, the clothing can be further clamped. The pressing portion 41 itself can be a plastic shell with a hollow interior to form the aforementioned second cavity, without affecting the magnetism of the second magnetic member 43.

[0083] In some embodiments, the first magnetic element 42 and the second magnetic element 43 can both be permanent magnets, such as neodymium iron boron magnets, ferrite magnets, etc., or the first magnetic element 42 can be a permanent magnet and the second magnetic element 43 can be a soft magnet, such as ferrite, silicon steel block, etc.

[0084] In some embodiments, the side of the fixing part 40 facing the pressing part 41 forms a first pressing surface 400, which may be a plane. The side of the pressing part 41 facing the fixing part 40 forms a second pressing surface 410, which may also be a plane. The second pressing surface 410 has at least two spaced first abutments 44 protruding toward the first pressing surface 400. When the pressing part 41 is connected to the fixing part 40, the aforementioned clamping space is formed between the first abutments 44 and the first pressing surface 400, and the clothing is clamped between the first pressing surface 400 and the first abutments 44, reducing the contact area between the clothing and the pressing part 41, making the clothing easier to dry.

[0085] In some embodiments, at least two first abutments 44 may be located at the edge of the projection of the first magnetic element 42 onto the second abutment surface 410, such that the first abutments 44 are offset from the second magnetic element 43, and the first abutments 44 do not affect the magnetic attraction between the first magnetic element 42 and the second magnetic element 43.

[0086] In some embodiments, the first pressing surface 400 has at least two spaced second abutments (not shown in the figure) protruding toward the second pressing surface 410. The at least two second abutments correspond one-to-one with the at least two first abutments 44. When the pressing part 41 is connected to the fixing part 40, the clamping space is formed between the first abutments 44 and the second abutments. The clothing is clamped between the first abutments 44 and the second abutments, further reducing the contact area between the clothing and the fixing part 40. The two sides of the clothing only contact the first abutments 44 and the second abutments. The part of the clothing located between the pressing part 41 and the fixing part 40 is suspended except for the part that contacts the first abutments 44 and the second abutments, thereby facilitating the evaporation of moisture from the clamped part of the clothing as much as possible. The clamped part of the clothing is easier to dry, avoiding uneven drying of the clothing after drying.

[0087] In some embodiments, at least two second abutments may be located at the edge of the projection of the second magnetic element 43 onto the first abutment surface 400, such that the second abutments are offset from the first magnetic element 42, and the second abutments do not affect the magnetic attraction between the first magnetic element 42 and the second magnetic element 43.

[0088] In some embodiments, two first abutments 44 and three or more second abutments may be provided. Multiple first abutments 44 may be provided, arranged in two rows on both sides of the projection of the first magnetic element 42 onto the second pressing surface 410. Multiple second abutments may be provided, arranged in two rows on both sides of the projection of the second magnetic element 43 onto the first pressing surface 400, thereby improving the stability of the clothing being clamped without affecting the magnetic attraction of the first magnetic element 42 and the second magnetic element 43.

[0089] In summary, in this embodiment, by setting at least two fixing members 4 to clamp different parts of the clothes, the clothes are spread out in the drying chamber 50 in a horizontal position. The contact area between the clothes and the hot air in the drying chamber 50 is larger, and the hot air can pass through the gaps between the clothes fibers more efficiently, accelerating the removal of moisture from the clothes, thereby improving the drying efficiency of a single garment, saving energy, and making it more economical.
