Referring to fig. 1 and 4, the embodiment of the present application provides a clothes drying device, the clothes drying device includes a housing 10, a wind wheel 20 and a dehumidifying device 30, the housing 10 is formed with a clothes drying chamber 10a, an air duct 10b, an air inlet 10c, an air supply opening 10d and an air outlet 10e, the air inlet 10c is communicated with the air duct 10b and the outside, the air supply opening 10d is communicated with the air duct 10b and the clothes drying chamber 10a, and the air outlet 10e is communicated with the clothes drying chamber 10a and the outside. The clothes drying chamber 10a is used for placing clothes, the wind wheel 20 is positioned in the air duct 10b, and the dehumidifying device 30 covers the air outlet 10e.

In the prior art, in the clothes drying process, the air flow flowing through the clothes to be dried absorbs moisture on the clothes to form high-temperature and high-water-content air flow, and the high-temperature and high-water-content air flow is generally and directly discharged to the indoor space in a concentrated mode, so that the humidity of the indoor space can be quickly improved in a short time, even the phenomenon of water drop spraying occurs at the air outlet of the clothes drying device, the indoor environment is greatly influenced, and the user experience is poor.

According to the clothes drying device provided by the embodiment of the application, the wind wheel 20 rotates to drive external air flow to enter the air duct 10b through the air inlet 10c, the air flow from the air duct 10b enters the clothes drying cavity 10a through the air supply outlet 10d, the air flow takes away moisture of clothes 1 to be dried to form air flow with high water content, the air flow with high water content flows through the dehumidifying device 30, the dehumidifying device 30 adsorbs the moisture in the air flow to form air flow with low water content, and the air flow with low water content is discharged to the outside through the air outlet 10e. On the one hand, the wind wheel 20 drives the air flow to circulate among the outside, the air duct 10b and the clothes drying cavity 10a, moisture from clothes in the air flow is absorbed through the dehumidifying device 30, the clothes are dried under the condition of no mechanical friction, the damage to the clothes is reduced, and the drying and nursing requirements of users on the clothes made of vulnerable materials are met. On the other hand, because dehydrating unit 30 covers air outlet 10e, the air current all need only absorb moisture through dehydrating unit 30 and just can discharge to the external world, like this, can avoid the air current of high water content directly blowing to the external world, avoid concentrating the air current of discharging high water content in the clothing drying process in the short time, lead to the problem that indoor space humidity increases rapidly, user experience is good.

The dehumidifying device 30 may be a reusable device. In one embodiment, the dehumidification device 30 is capable of adsorbing and desorbing moisture. That is, the adsorption process of the dehumidifying device 30 is reversible, and the moisture adsorbed by the dehumidifying device 30 can escape from the dehumidifying device 30 and re-enter the air flow. In this way, the dehumidifying device 30 can be reused, improving the user experience. Because the desorption of the dehumidifying device 30 is a slow release process for a long time, the air flow with high water content is not discharged in a short time, and the indoor humidity is not caused.

Illustratively, the dehumidifying device 30 may be made of zeolite or metal-organic framework (Metal Organic Framework, MOF) material. It should be noted that the MOF material is a coordination polymer, has a three-dimensional pore structure, generally uses metal ions as connection points, and supports an organic ligand to form a space three-dimensional extension, and is another important novel porous material besides zeolite and carbon nanotubes, and has wide application in catalysis, energy storage and separation. The MOF material has better water absorption, and can be desorbed in a lower temperature range (for example, about 80 ℃) in the desorption process.

The specific shape of the dehumidifying apparatus 30 is not limited, and the dehumidifying apparatus 30 is exemplified as a flat plate-like structure, and the dehumidifying apparatus 30 includes at least two layered adsorption plates made of MOF materials. In this way, the dehumidifier 30 can be more favorably attached to the air outlet 10e.

In an embodiment, referring to fig. 1 to 4, the air duct 10b includes an air inlet section 10b ' and an air supply section 10b″ communicating with the air inlet section 10b ', the air supply section 10b″ is located below the clothes drying chamber 10a, the air inlet section 10b ' is located at one side of the air supply section 10b″ perpendicular to the up-down direction of the housing 10 and communicates with the air inlet 10c, and the air supply opening 10d is formed on the lower surface of the clothes drying chamber 10a and communicates with the air supply section 10b″. That is, the air intake section 10b' is located at one side of the air supply section 10b″ in the front-rear direction of the casing 10 or one side of the casing 10 in the left-right direction. The clothes drying chamber 10a is overlapped above the air supply section 10b ", the air inlet section 10b 'is positioned at one side of the air supply section 10b' in the front-rear direction or one side of the air supply section 10b 'in the left-right direction, so that the layout between the air inlet section 10b', the air supply section 10b 'and the clothes drying chamber 10a is compact, under the condition that the clothes drying chamber 10a has a large volume, the plane perpendicular to the up-down direction is taken as a section, the section area of the air supply section 10b' and the section area of the clothes drying chamber 10a can be large, so that the air supply opening 10d can be large, more air flows can enter the clothes drying chamber 10a, and the dimension of the shell 10 in the height direction can be small, so that the clothes drying device is convenient to be miniaturized, and a user can place the clothes drying device in a bedroom or living room and other indoor spaces.

In the embodiment of the present application, the vertical direction, the front-rear direction, and the left-right direction of the housing 10 are perpendicular to each other, and together form a three-dimensional vertical coordinate system, wherein the top side coincides with the upper side, and the bottom side coincides with the lower side.

In one embodiment, referring to fig. 4, a communication port 10b '"is formed on a peripheral side surface of the air inlet section 10b' near the air supply section 10b", and the communication port 10b '"communicates the air inlet section 10b' with the air supply section 10b". For example, the air intake section 10b ' is located at the rear side of the air supply section 10b ", and the front side of the air intake section 10b ' is formed with a communication port 10b '". Thus, the pipeline arrangement between the air inlet section 10b' and the air supply section 10b″ is reduced, and the structure of the clothes drying device is more compact.

The particular type of rotor 20 is not limited, and exemplary rotors 20 include, but are not limited to, cross-flow rotors and centrifugal rotors. The noise of the cross flow wind wheel is small, and the noise is prevented from disturbing the user. The centrifugal wind wheel has large air quantity, and is convenient for quick drying of clothes.

In one embodiment, the clothes drying apparatus includes a wind wheel motor connected to the wind wheel 20 to drive the wind wheel 20 to rotate. Thus, the degree of automation is high.

The specific structure of the air supply section 10b″ is not limited, and in an exemplary embodiment, referring to fig. 4, the casing 10 is configured with a volute tongue 12 and a side plate 13, the volute tongue 12 is disposed above the side plate 13 at a distance, one ends of the volute tongue 12 and the side plate 13 are connected to the surrounding portion of the communication port 10b' ″ respectively, the other ends of the volute tongue 12 and the side plate 13 are connected to the surrounding portion of the air supply port 10d respectively, and the space between the volute tongue 12 and the side plate 13 is the air supply section 10 b). In this way, the air supply section 10b″ formed by the volute tongue 12 and the side plate 13 can perform a diffusion function and reduce turbulence in the air flow process.

The specific structure of the air intake section 10b 'is not limited, and in an exemplary embodiment, referring to fig. 4, the extending direction of the air intake section 10b' is consistent with the axis of the wind wheel 20. For example, the air intake section 10b 'is located at the rear side of the air supply section 10b″, the air intake section 10b' extends in the left-right direction, and the axis of the wind wheel 20 is disposed in the left-right direction. Thus, the size of the communication port 10b' "can be large to secure the air volume.

In one embodiment, referring to fig. 4, the wind wheel 20 is located in the air intake section 10 b'. On the one hand, the wind wheel 20 is positioned in the air inlet section 10b' so as to ensure a large air quantity. On the other hand, since the air supply section 10b″ is located below the clothes drying chamber 10a, under the condition of high humidity of clothes, water on the clothes may condense into water droplets, and the water droplets may drop into the air outlet section through the air supply port 10d, so that the air wheel 20 is arranged in the air inlet section 10b' to avoid the water droplets from contacting the air wheel 20 to a certain extent.

In an embodiment, referring to fig. 4, a dehumidifying chamber 10g is formed in the housing 10, the dehumidifying chamber 10g is located at one side of the clothes drying chamber 10a far away from the air supply opening 10d, an air outlet 10e is formed on the surface of the dehumidifying chamber 10g far away from the clothes drying chamber 10a, an air vent 10g 'communicating the dehumidifying chamber 10g and the clothes drying chamber 10a is formed on the surface of the dehumidifying chamber 10g near the clothes drying chamber 10a, and the dehumidifying device 30 is disposed in the dehumidifying chamber 10g and covers the air vent 10g'. On the one hand, the time during which the air flow flows in the laundry drying chamber 10a may be relatively long, so that the air flow contacts the laundry 1 to be dried for a relatively long time, thereby enabling the air flow to take away more moisture. On the other hand, since the dehumidifying device 30 covers the air vent 10g 'and the air outlet 10e, the air flow with high water content from the air vent 10g' can enter the dehumidifying cavity 10g after passing through the dehumidifying device 30, and can be discharged through the air outlet opening after fully contacting with the dehumidifying device 30, so that the dehumidifying effect of the air flow is ensured.

For example, in one embodiment, referring to fig. 4, the dehumidifying chamber 10g is located above the laundry drying chamber 10a, the top surface of the dehumidifying chamber 10g is formed with an air outlet 10e, and the bottom surface of the dehumidifying chamber 10g is formed with an air vent 10g'. The design is compact in structure, and the position of the clothes drying cavity 10a is closer to the lower part, so that under the condition that clothes are placed in the clothes drying cavity 10a, the gravity center of the clothes drying device is close to the lower part of the shell 10, and therefore stability of the clothes drying device is kept, and the phenomenon that the gravity center of the clothes drying device is unstable and topples over is avoided to a certain extent.

In one embodiment, referring to fig. 1 and 2, at least one of the left and right sides of the housing 10 is formed with an air inlet 10c. For example, the left side surface of the housing 10 may be formed with an air inlet 10c. For another example, the right side surface of the housing 10 may be formed with an air inlet 10c. For another example, the left and right sides of the housing 10 are each formed with an air inlet 10c. Thus, on the one hand, when the clothes drying device is placed on the wall, the wall is prevented from interfering with the air flow entering the air inlet 10c to a certain extent, and on the other hand, the air flow is convenient to enter the air inlet 10c in a large amount.

In an embodiment, referring to fig. 1, a grid plate may be covered at the air inlet 10c, where the grid plate has a plurality of air holes. Thus, the user or the object is prevented from contacting the dehumidifying device 30 through the air inlet 10c, and the safety is good.

In the clothes drying device, the wind wheel 20 is used for driving the air flow in the cavity to move, and the driving capability of the wind wheel 20 is weak in the area far away from the wind wheel 20, so that the air flow is not easy to move in the expected direction, and the air flow is in a disordered state; meanwhile, because the moisture content, the thickness and the like of each part of the clothes are different, the disordered air flow cannot ensure sufficient contact with each part of the clothes, so that the drying degree of each part of the clothes is different, for example, in the state that some parts of the clothes near the wind wheel 20 are dried, the humidity of other parts of the clothes far away is still larger, and thus, the drying time of the clothes is longer and the drying effect is uneven. In an embodiment of the present application, referring to fig. 4, a guide rib 11 is formed on an inner bottom surface of the air supply section 10b ", and the guide rib 11 extends toward a side of the clothes drying chamber 10a. That is, the deflector rib 11 extends substantially upward. On the one hand, the air flow guiding ribs 11 can play a role in guiding air, the air flow from the air supply section 10b ' can be blown to each area of the air supply section 10b ' under the action of self kinetic energy, and the air flow in each area of the air supply section 10b ' can smoothly enter the clothes drying cavity 10a under the guiding of the air flow guiding ribs 11, so that the air flow in the air supply section can be distributed in a dispersed manner and can smoothly enter the clothes drying cavity, so that the air flow can be blown to each area of the clothes drying cavity, and particularly, the air quantity of the area far away from the wind wheel 20 is enhanced, so that the air flow can be fully contacted with each part of clothes to be dried in the clothes drying cavity, so that the clothes can be dried uniformly and efficiently, the clothes drying time can be effectively shortened, and the drying effect is good. On the other hand, the water droplets which may be formed can be limited to flow to the air inlet section 10b' by the guide ribs 11, so that the safety is good.

The number of the guide ribs 11 is not limited, and the number of the guide ribs 11 may be one. In an embodiment, referring to fig. 4, the number of the guide ribs 11 is plural, and the plurality of guide ribs 11 are spaced from the air inlet section 10b 'to the air inlet section 10 b'. For example, the air inlet section 10b' is located at the rear side of the air supply section 10b″ and the air guide ribs 11 are spaced apart along the front-rear direction of the housing 10. So designed, on the one hand, after the air flow from the air inlet section 10b ' enters the air supply section 10b″ through the communication port 10b ' ", the plurality of guide ribs 11 can guide the air flow from the air inlet section 10b ' more uniformly to each region of the laundry drying chamber 10a so as to dry the laundry more uniformly. On the other hand, the plurality of guide ribs 11 can better restrict the inflow of water droplets into the air intake section 10 b'.

The term "plurality" refers to two or more.

In an embodiment, referring to fig. 4, the height of the guide rib 11 near the air inlet section 10b 'is smaller than the height of the guide rib 11 far from the air inlet section 10 b'. That is, in the height direction of the housing 10, the height H of each of the guide ribs 11 increases from being close to the air intake section 10b 'to being far from the air intake section 10 b'. For example, the height H of each of the ribs 11 may gradually increase from the vicinity of the air intake section 10b 'to the distal end of the air intake section 10 b'. In this way, the air flow is prevented from being excessively blocked by the guide rib 11 close to the air inlet section 10b ', so that part of the air flow can flow to the position far away from the air inlet section 10b ', and the air flow moving far away from the air inlet section 10b ' is prevented from being difficult to enter the clothes drying cavity 10a, so that the other part of the air flow can enter the clothes drying cavity 10a under the action of the guide rib 11, and the air flow can be uniformly blown to each area of the clothes drying cavity 10a, so that clothes can be dried rapidly and uniformly, and the drying efficiency and the drying effect are improved.

In an embodiment, referring to fig. 4, the height of the portion of the inner bottom surface of the air supply section 10b″ near the air intake section 10b 'is lower than the height of the portion of the inner bottom surface of the air supply section 10b″ far from the air intake section 10 b'. The kinetic energy of the air flow close to the air inlet section 10b ' is relatively large, the kinetic energy of the air flow far away from the air inlet section 10b ' is relatively small, and the height of the part of the inner bottom surface of the air supply section 10b ' far away from the air inlet section 10b ' is large, so that the air flow far away from the air inlet section 10b ' can smoothly enter the clothes drying cavity 10a, and the clothes are blown to the clothes at a large flow rate.

For example, in one embodiment, referring to fig. 4, the side plate 13 of the air supply section 10b″ has an arc surface structure, and the distance L between the side plate 13 and the inner bottom surface of the housing 10 gradually increases from the vicinity of the air intake section 10b 'to the vicinity of the air intake section 10 b'. Thus, the height of the inner bottom surface of the air supply section 10b″ at the position close to the air intake section 10b 'is lower than the height of the inner bottom surface of the air supply section 10b″ at the position far from the air intake section 10 b'.

In one embodiment, referring to fig. 4 and 5, the clothes drying apparatus includes a rack 40 located in the clothes drying chamber 10a, where the rack 40 has at least one placement layer 41, and the placement layer 41 is used for placing clothes. That is, the laundry can be generally laid flat on the placement layer 41. In this way, on the one hand, the laundry can be stretched as much as possible so that the laundry is in large-area full contact with the air flow in the laundry drying chamber 10a, thereby rapidly drying the laundry; on the other hand, the problems of clothes winding, wrinkling and the like can be reduced to a certain extent, and the user experience is improved.

In one embodiment, referring to fig. 4 and 5, the placement layer 41 is disposed along a direction perpendicular to the airflow direction of the laundry drying chamber 10a. For example, the air flow from the air supply section 10b″ is blown from the bottom to the top toward the laundry drying chamber 10a, and the placement layer 41 is disposed in a substantially horizontal direction. Thus, the contact area of the clothes and the air flow is large, so that the clothes can be dried quickly and uniformly.

The horizontal direction is perpendicular to the up-down direction of the housing 10.

The number of the placement layers 41 is not limited, and the placement layers 41 may be one or a plurality of placement layers. In an exemplary embodiment, the plurality of storage layers 41 are provided, and the plurality of storage layers 41 are disposed at intervals along the up-down direction. The plurality of storage layers 41 facilitate placement of more clothes and also facilitate more spreading of clothes on the storage layers 41, for example, when the clothes are smaller in size, multiple clothes can be placed on one storage layer 41 or multiple storage layers 41; when the garment is large or thick, different portions of a garment may be placed on different storage layers 41.

The specific structure of the placement layer 41 is not limited, and in an exemplary embodiment, the placement layer 41 is formed with a plurality of through holes. That is, the storage layer 41 has a porous structure, so that the air flow is convenient to fully contact the laundry on the storage layer 41.

In one embodiment, referring to fig. 5, the housing 10 is formed with a taking and placing opening 10f, the laundry drying apparatus includes a shielding door 50, the shelf 40 can be inserted into or pulled out of the laundry drying chamber 10a through the taking and placing opening 10f, and the shielding door 50 can shield or open the taking and placing opening 10f. The shelf 40 is inserted into the laundry drying chamber 10a in a state where the shielding door 50 shields the access opening 10f (see fig. 1), and the shelf 40 is at least partially pulled out of the laundry drying chamber 10a in a state where the shielding door 50 opens the access opening 10f (see fig. 5). In this way, the rack 40 can be pulled out of the clothes drying cavity 10a, so that a user can conveniently and rapidly place the clothes 1 to be dried on the rack 40, then insert the rack 40 into the clothes drying cavity 10a, the shielding door 50 shields the putting opening, and the clothes drying device can enter a drying state. After the clothes are dried, the shielding door 50 opens the feeding opening, and the user pulls the shelf 40 out of the clothes drying chamber 10a, so that the clothes can be quickly taken out.

In one embodiment, referring to fig. 4 and 5, a shutter 50 is connected to the shelf 40. That is, the shelf 40 and the shielding door 50 can move synchronously. Thus, the user applies force to move the shielding door 50 to drive the shelf 40 to move synchronously.

In one embodiment, referring to fig. 5, the access opening 10f may be located on a front side of the housing 10 facing the user. In this way, the back side of the clothes drying device is conveniently placed close to the wall as much as possible.

In one embodiment, the shielding door 50 can hermetically shield the pick-and-place port 10f, so that air leakage from a gap between the shielding door 50 and a portion around the pick-and-place port 10f during the drying process can be avoided. For example, a seal ring may be provided at the shielding door 50 or the pick-and-place port 10f to seal a gap between the shielding door 50 and a portion around the pick-and-place port 10f.

To facilitate the shielding door 50 to firmly shield the access opening 10f, in an embodiment, the shielding door 50 may be detachably connected to the housing 10, such as a snap-fit or magnetic connection, etc. In this way, the shutter door 50 opens the access opening 10f when the laundry drying apparatus is prevented from shaking or the like.

In one embodiment, referring to fig. 5, a handle 51 is formed on a surface of the shielding door 50 away from the rack 40, and a user holds the handle 51 to pull the shielding door 50.
