Description

Technical Field

[0001] The present invention relates to the technical field of indoor dehumidification equipment, and particularly to a dehumidification and drying equipment. Background Art

[0002] In humid seasons, such as the rainy season and the period of humid weather known as "returning south" in some regions, the indoor environment is prone to becoming humid. It is difficult for clothes to dry naturally, and indoor dehumidification equipment is usually used to dehumidify the indoor environment. Indoor dehumidification equipment generally consists of a housing, a compressor, an evaporator, a condenser, a wind wheel, a motor, and a volute casing built into the housing. An air outlet is provided at the top of the housing, and an air inlet is provided on the side of the housing. Since the air outlet is located at the top of the housing, the hot air blown out from the air outlet generally acts on the upper half of the clothes, but cannot act on the lower half of the clothes. Due to the action of gravity, most of the moisture in the clothes accumulates in the lower half of the clothes, resulting in the lower half of the clothes being often wetter than the upper half. Without the action of hot air flow, the drying of the lower half of the clothes is very slow. Summary of the Invention

[0003] Based on this, the present invention provides a dehumidification and drying equipment, which solves the problems of low drying efficiency of traditional indoor dehumidification equipment and the inability of hot air to act on the lower half of clothes.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A dehumidification and drying equipment, comprising a box body, a dehumidification component, and a fan component. An accommodation cavity is defined inside the box body. An air return part communicating with the accommodation cavity is penetrated and opened above the front side of the box body. The dehumidification component and the fan component are arranged in the accommodation cavity. The fan component is provided with an air inlet part, a first air outlet part, and a second air outlet part. The dehumidification component is mounted between the air return part and the air inlet part;

[0006] An upper air collection cavity is defined at the rear side of the box body. An upper air outlet is penetrated and opened above the upper air collection cavity. The first air outlet part is communicated with the upper air collection cavity; The second air outlet part is penetrated and arranged below the front side of the box body, and the positions of the second air outlet part are all lower than the positions of the upper air outlet and the air return part.

[0007] Accordingly, in the embodiment of the present invention, by arranging the return air part above the front side of the box body, the water vapor volatilized from the clothes can be quickly sucked into the accommodation cavity. After being evaporated and dried by the dehumidification component, dry hot air is blown out from the first air outlet part and the second air outlet part of the fan component respectively. By arranging the upper air outlet above the box body and the second air outlet part below the box body, the hot air blown out from the upper air outlet and the second air outlet part can dry the upper half area and the lower half area of the clothes respectively, which can greatly improve the drying efficiency of the clothes. On the other hand, by arranging the return air part in the area between the upper air outlet and the second air outlet part, the water vapor volatilized from the clothes can be more effectively absorbed by the return air part, thereby effectively reducing the humidity of the ambient air and further improving the drying efficiency of the equipment.

[0008] As an implementation manner, an upper air collecting cover is arranged at the rear side of the box body. The upper air collecting cover and the rear side of the box body jointly form the upper air collecting cavity. The first air outlet part penetrates through the rear side of the box body and is communicated with the upper air collecting cavity; the top of the upper air collecting cover extends above the top of the box body. Accordingly, in the embodiment of the present invention, the upper air collecting cavity is formed by the upper air collecting cover and the box body, and the top of the upper air collecting cover extends obliquely upward toward the front side of the box body, so that the upper air outlet can blow hot air toward the front side above the box body, thereby drying the upper half area of the clothes.

[0009] As an implementation manner, the part of the upper air collecting cover extending above the box body is bent toward the front side of the box body, so that the air outlet direction of the upper air outlet faces the front side above the box body. Accordingly, in the embodiment of the present invention, by bending the part of the upper air collecting cover extending above the box body toward the front side of the box body, the top of the upper air collecting box can play a role in guiding the air flow. In this way, the hot air blown out from the upper air outlet can be blown toward the front side above the box body and act on the upper half area of the clothes.

[0010] As an implementation manner, an upper air duct cover is arranged in the accommodation cavity. The upper air duct cover and the rear side of the box body jointly define an upper air duct cavity. An upper air guiding opening for communicating the upper air collecting cavity and the upper air duct cavity is formed through the rear side of the box body. The first air outlet part is communicated with the upper air duct cavity. Accordingly, in the embodiment of the present invention, by arranging the upper air duct cover in the accommodation cavity, it is convenient for the first air outlet part of the fan component to be flexibly and reasonably arranged in the accommodation cavity. By communicating the first air inlet part with the upper air duct cavity, the hot air sent out from the first air outlet part can pass through the upper air duct cavity, the upper air collecting cavity and be blown out from the upper air outlet.

[0011] As an implementation manner, a lower air collecting cavity is defined below the front side of the box body. An air outlet is formed through the upper part of the lower air collecting cavity. The second air outlet part is communicated with the lower air collecting cavity. The positions of the lower air outlets are lower than those of the upper air outlet and the air return part. Thus, in the embodiment of the present invention, by defining a lower air collecting cavity below the front side of the box body, the hot air sent out from the second air outlet part can be better collected through the lower air collecting cavity and sent out through the lower air outlets to dry the lower half area of the clothes. That is to say, in the embodiment of the present invention, two hot air flows with different heights can be sent out respectively through the lower air outlets arranged below the front side of the box body and the upper air outlet arranged above the top of the box body, and the upper half area and the lower half area of the clothes are dried respectively, thereby greatly improving the drying efficiency of the clothes. On the other hand, by arranging the air return part in the area between the upper air outlet and the second air outlet part, the water vapor volatilized from the clothes can be more effectively absorbed by the air return part, thereby effectively reducing the humidity of the ambient air and further improving the drying efficiency of the equipment.

[0012] As an implementation manner, a lower air collecting box is arranged below the front side of the box body. The lower air collecting cavity is defined inside the lower air collecting box. A lower air guiding opening for communicating the second air outlet part and the lower air collecting cavity is arranged on one side of the lower air collecting box connected to the box body. Thus, in the embodiment of the present invention, the lower air collecting box is connected to the lower front side of the box body, the lower air collecting cavity is defined inside the lower air collecting box, and the second air outlet part and the lower air collecting cavity are communicated through the lower air guiding opening, so that the hot air sent out from the second air outlet part can enter the lower air collecting cavity and be sent out through the lower air outlets.

[0013] As an implementation manner, a stepping motor and a rotating air nozzle are arranged inside the lower air collecting cavity. The stepping motor is drivingly connected to the rotating air nozzle and is used to drive the rotating air nozzle to rotate. The rotating air nozzle is located below the lower air outlet. Thus, in the embodiment of the present invention, by arranging a stepping motor inside the lower air collecting cavity, the stepping motor drives the rotating air nozzle to rotate, and the air flow blown out from the lower air outlet can be sent out at different angles after swinging through the rotating air nozzle, so as to achieve the effect that the air outlet angle can be automatically adjusted and make the drying process more uniform.

[0014] As an implementation manner, the fan assembly includes a driving motor, rotating shafts are respectively arranged at both ends of the driving motor, and a first centrifugal fan and a second centrifugal fan are coaxially and rigidly connected to the rotating shafts at both ends of the driving motor respectively. A first volute and a second volute are respectively disposed on the outer peripheral sides of the first centrifugal fan and the second centrifugal fan. The first air outlet part is arranged on the first volute, and the second air outlet part is arranged on the second volute. The first volute and the second volute are respectively provided with a first air inlet and a second air inlet, and the first air inlet and the second air inlet together form the air inlet part of the fan assembly. Thus, through the structural design of the double volutes in the embodiment of the present invention, the fan assembly can more reasonably separately form the first air outlet part and the second air outlet part, so as to facilitate the connection and layout between the fan assembly and the upper air collecting cavity and the lower air collecting cavity respectively, and enable the device to achieve the effect of discharging air above the box body and below the front side of the box body respectively.

[0015] As an implementation manner, the axes of the first volute and the second volute are both parallel to the width direction of the box body; the first air inlets are respectively provided through both ends of the first volute, and both ends of the first volute are respectively arranged at intervals from the inner wall of the accommodating cavity and the driving motor; the second air inlets are respectively provided through both ends of the second volute, and both ends of the second volute are respectively arranged at intervals from the inner wall of the accommodating cavity and the driving motor; the first air outlet part and the second air outlet part are both arc-shaped air duct structures. Thus, in the embodiment of the present invention, the first air inlets at both ends of the first volute and the second air inlets at both ends of the second volute are respectively used as their own air inlets, and both ends of the two volutes are spaced apart from the driving motor and the inner wall of the accommodating cavity by a certain distance to ensure smooth air intake of the two volutes and reduce wind noise.

[0016] As an implementation manner, a first air return opening is provided at the top of the box body, the front side of the box body inclines backward to form an inclined surface, and a second air return opening is provided on the inclined surface. The first air return opening and the second air return opening together form the air return part. Thus, in the embodiment of the present invention, an inclined surface is provided above the front side of the box body, and the second air return opening is provided on the inclined surface to form an upward inclined air return angle, which is beneficial to improving the air intake efficiency above the box body; at the same time, the design of the inclined surface can also prevent the hanging clothes from completely blocking the second air return opening, and the first air return opening at the top of the box body is used as auxiliary air intake to ensure smooth air intake of the device.

[0017] As an implementation manner, the dehumidification component includes an evaporator, a condenser, and a compressor that are sequentially arranged at intervals in the accommodation cavity along the vertical direction of the accommodation cavity. The evaporator is arranged parallel to the inclined surface and is located on one side of the second air return opening. The condenser is arranged perpendicular to the evaporator, and a water receiving tray is arranged between the condenser and the evaporator. The water receiving tray is located below the evaporator, and the compressor is respectively connected to the evaporator and the condenser. Thus, in the embodiment of the present invention, by arranging the evaporator, the condenser, and the fan assembly vertically, the thickness of the box body can be made smaller, which is beneficial to placing the box body against the wall and saves more space.

Detailed implementation manners

[0033] To further illustrate the embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the present invention.

[0034] In humid seasons, such as the rainy season, the return of the south, etc., the indoor environment is prone to become humid, and it is very difficult for clothes to dry naturally. People usually use indoor dehumidification equipment to dehumidify the indoor environment.

[0035] As Figure 1 shown, traditional indoor dehumidification equipment usually consists of a housing, a compressor, an evaporator, a condenser, a fan wheel, a motor, and a volute built into the housing. An air outlet is provided at the top of the housing, and an air inlet is provided on the side of the housing. In the area between the air inlet and the air outlet, the evaporator, the condenser, the fan wheel, and the motor are arranged horizontally and sequentially. The motor drives the fan wheel to rotate at a high speed, sucks in the humid air from the air inlet on the side of the housing, then condenses the humid air into water droplets through the evaporator and discharges it, heats it through the condenser, and then discharges the dry air from the air outlet at the top of the housing, thereby dehumidifying the indoor environment. Usually, indoor dehumidification equipment can also be used to dry wet clothes. Hang the wet clothes on a drying rod, and then place the dehumidification equipment close to the wet clothes and make the air outlet face the wet clothes to blow air.

[0036] It can be seen that the air outlet of the traditional dehumidification device is arranged at the top of the housing, and the hot air blown out from the air outlet directly acts on the upper half of the clothes, but cannot act on the lower half of the clothes. However, most of the moisture in the clothes accumulates in the lower half of the clothes under the action of its own gravity. Therefore, the lower half of the clothes is often wetter than the upper half, and the hot air cannot blow to the lower half of the clothes, resulting in a very low drying efficiency of the lower half of the clothes. On the other hand, since the air return port of the traditional device is arranged on the side and lower than the air outlet, the air flow blown out from the air outlet is likely to blow the moist air above the air return port far away, making the dehumidification efficiency of the air return port low.

[0037] Based on this, the embodiment of the present invention provides a dehumidifying and drying device, which solves the problems of low drying efficiency of the traditional indoor dehumidification device and the inability of hot air to act on the lower half of the clothes.

[0038] Please refer to Figures 1 to 12 ; The embodiment of the present invention provides a dehumidifying and drying device, including a box body 10, a dehumidifying component, and a fan component 24. An accommodating cavity is defined inside the box body 10. An air return part 13 communicating with the accommodating cavity is penetrated and opened above the front side of the box body 10. The dehumidifying component and the fan component 24 are arranged in the accommodating cavity. The fan component 24 is provided with an air inlet part, a first air outlet part 32, and a second air outlet part 33. The dehumidifying component is erected between the air return part 13 and the air inlet part; in addition, an upper air collecting cavity is defined at the rear side of the box body 10, and an upper air outlet 19 is penetrated and opened above the upper air collecting cavity. The first air outlet part 32 is communicated with the upper air collecting cavity; the second air outlet part 33 is penetrated and arranged below the front side of the box body 10, and the positions of the second air outlet parts 33 are lower than the positions of the upper air outlet 19 and the air return part 13.

[0039] Thus, in the embodiment of the present invention, by arranging the air return part 13 above the front side of the box body 10, the water vapor volatilized from the clothes can be quickly sucked into the accommodating cavity. After being evaporated and dried by the dehumidifying component, dry hot air is blown out from the first air outlet part 32 and the second air outlet part 33 of the fan component 24 respectively. By arranging the upper air outlet 19 above the box body 10 and the second air outlet part 33 below the box body 10, the hot air blown out from the upper air outlet 19 and the second air outlet part 33 can dry the upper half and the lower half of the clothes respectively, which can greatly improve the drying efficiency of the clothes. On the other hand, by arranging the air return part 13 in the area between the upper air outlet 19 and the second air outlet part 33, the water vapor volatilized from the clothes can be more effectively absorbed by the air return part 13, thereby effectively reducing the humidity of the ambient air and further improving the drying efficiency of the device.

[0040] In an embodiment of the present invention, the accommodation cavity serves as a cavity structure for installing a dehumidification component and a fan component 24. An air return portion 13 communicating with the accommodation cavity is provided above the front side of the box body 10, so that the air return portion 13, the accommodation cavity, and the air inlet portion of the fan component 24 together form an air inlet channel inside the box body 10. In this way, under the drive of the fan component 24, a strong suction force is generated at the air inlet portion, so that the air near the air return portion 13 can be quickly sucked into the interior of the accommodation cavity. Then, after being dried by the dehumidification component, dry hot air is formed and enters the interior of the fan component 24, and then is sent out from the first air outlet portion 32 and the second air outlet portion 33 of the fan component 24 respectively, so as to achieve the effect of drying the upper half area and the lower half area of the clothes respectively.

[0041] As Figure 2 , Figure 3 and Figure 4 shown, the box body 10 of the embodiment of the present invention can be formed by splicing a front cover 11 and a rear cover 12 to form a closed structure, so that the airtightness of the accommodation cavity defined inside the box body 10 is good. In an embodiment of the present invention, a first air return opening 14 is provided at the top of the box body 10. The front side of the box body 10 slopes backward to form an inclined surface, and a second air return opening 15 is provided on the inclined surface. The first air return opening 14 and the second air return opening 15 together form the air return portion 13. In this way, in the embodiment of the present invention, by providing an inclined surface above the front side of the box body 10 and providing a second air return opening 15 on the inclined surface, an upwardly inclined air return angle is formed, which is beneficial to improving the air inlet efficiency above the box body 10; at the same time, the design of the inclined surface can also prevent the hanging clothes from completely blocking the second air return opening 15, and the first air return opening 14 at the top of the box body 10 is used as auxiliary air inlet to ensure the smooth air inlet of the device.

[0042] As Figure 5 shown, the dehumidification component of the embodiment of the present invention includes an evaporator 20, a condenser 22, and a compressor 23 that are sequentially arranged at intervals in the accommodation cavity along the vertical direction of the accommodation cavity. The evaporator 20 is arranged parallel to the inclined surface, and the evaporator 20 is located on one side of the second air return opening 15. The condenser 22 is arranged perpendicular to the evaporator 20, and a water receiving tray 21 is provided between the condenser 22 and the evaporator 20. The water receiving tray 21 is located below the evaporator 20. The compressor 23 is respectively connected to the evaporator 20 and the condenser 22. In this way, in the embodiment of the present invention, by arranging the evaporator 20, the condenser 22, and the fan component 24 in a vertical layout, the thickness of the box body 10 can be made smaller, which is beneficial to placing the box body 10 against the wall and saves more space.

[0043] Among them, the evaporator 20 of the embodiment of the present invention, the first air return opening 14, and the second air return opening 15 together form an air return passage, so as to ensure that the humid air entering from the first air return opening 14 and the second air return opening 15 first passes through the evaporator 20 and is evaporated by the evaporator 20, so that the water vapor in the air can be evaporated and collected in the water receiving tray 21, and then after being heated and dried by the condenser 22, the air finally entering the fan assembly 24 is dry hot air.

[0044] For the convenience of installing and fixing the evaporator 20, the condenser 22, and the compressor 23, in the embodiment of the present invention, a first fixing plate for fixedly installing the evaporator 20, a second fixing plate for fixedly installing the condenser 22, and a third fixing plate for fixedly installing the compressor 23 are provided in the accommodating cavity. In addition, in order to facilitate the discharge of the water in the water receiving tray 21 to the outside, a drain hole is opened on the side wall of the water receiving tray 21, and a drain pipe is communicated at the drain hole. In this way, the water in the water receiving tray 21 can be discharged to the floor drain or other water tanks through the drain pipe.

[0045] As Figure 6 and Figure 7 As shown, the fan assembly 24 of the embodiment of the present invention includes a driving motor 25. Rotating shafts are respectively arranged at both ends of the driving motor 25, and a first centrifugal impeller 26 and a second centrifugal impeller 27 are coaxially and rigidly connected to the rotating shafts at both ends of the driving motor 25 respectively. First volutes 28 and second volutes 30 are respectively sleeved outside the first centrifugal impeller 26 and the second centrifugal impeller 27. A first air outlet part 32 is arranged on the first volute 28, a second air outlet part 33 is arranged on the second volute 30, first air inlets 29 and second air inlets 31 are respectively arranged on the first volute 28 and the second volute 30, and the first air inlets 29 and the second air inlets 31 together form the air inlet part of the fan assembly 24.

[0046] Furthermore, the axes of the first volute 28 and the second volute 30 in the embodiments of the present invention are both parallel to the width direction of the box body 10; in this way, in the embodiments of the present invention, the first volute 28 and the second volute 30 are horizontally arranged inside the box body, so that the axes of the first air inlet 29 at both ends of the first volute 28 and the second air inlet 31 at both ends of the second volute 30 are perpendicular to the vertical direction of the box body 10, so that the first volute 28 and the second volute 30 can both be provided with air outlet structures on their respective circumferential side walls. In addition, the first air inlets 29 are respectively provided through both ends of the first volute 28, and both ends of the first volute 28 are spaced apart from the inner wall of the accommodation cavity and the driving motor 25; the second air inlets 31 are respectively provided through both ends of the second volute 30, and both ends of the second volute 30 are spaced apart from the inner wall of the accommodation cavity and the driving motor 25; the first air outlet part 32 and the second air outlet part 33 are both arc-shaped air duct structures. In this way, in the embodiments of the present invention, the first air inlets 29 at both ends of the first volute 28 and the second air inlets 31 at both ends of the second volute 30 are respectively used as their respective air inlets, and both ends of the two volutes are spaced apart from the driving motor 25 and the inner wall of the accommodation cavity by a certain distance to ensure smooth air intake of the first volute 28 and the second volute 30 and reduce wind noise.

[0047] In order to facilitate the installation and fixation of the fan assembly 24, in the embodiments of the present invention, the fan assembly 24 further includes a fan fixing seat 34 and a fixing pressing plate 35. The fan fixing seat 34 is arranged at the bottom of the accommodation cavity, the driving motor 25 is fixedly installed on the fan fixing seat 34, and the first volute 28 and the second volute 30 are respectively fixedly installed on the fan fixing seat 34 through the fixing pressing plate 35. Among them, the axis of the driving motor 25 in the embodiments of the present invention is parallel to the width direction of the accommodation cavity, and the ports of the arc-shaped air outlet parts of the two volutes are arranged through the front bottom of the box body 10.

[0048] It can be understood that in the embodiments of the present invention, through the first volute 28, the second volute 30 and the first centrifugal impeller 26 and the second centrifugal impeller 27 respectively arranged in the first volute 28 and the second volute 30, the fan assembly 24 can have two relatively independent air inlet and outlet structures, and the driving motor 25 drives the first centrifugal impeller 26 and the second centrifugal impeller 27 to rotate synchronously, so that the first volute 28 and the second volute 30 respectively intake and supply air independently. In some other embodiments, the fan assembly 24 can also be an air inlet and outlet structure composed of a single volute and a single centrifugal impeller. In this way, in this embodiment, it is necessary to simultaneously arrange the first air outlet part 32 and the second air outlet part 33 on the same volute, and its layout is relatively cumbersome, and the wind power sent out from the first air outlet part 32 and the second air outlet part 33 is relatively small.

[0049] Such as Figure 5 and Figure 8As shown in the figure, a top air collecting cover 16 is provided at the rear side of the box body 10 of the embodiment of the present invention. The top air collecting cover 16 and the rear side of the box body 10 together form a top air collecting cavity. The first air outlet part 32 penetrates through the rear side of the box body 10 and is communicated with the top air collecting cavity; the top of the top air collecting cover 16 extends above the top of the box body 10, and the part of the top air collecting cover 16 extending above the box body 10 is bent towards the front side of the box body 10, so that the air outlet direction of the upper air outlet 19 faces the upper front side of the box body 10. In this way, in the embodiment of the present invention, the top air collecting cavity is formed by the top air collecting cover 16 and the box body 10, and the top of the top air collecting box 36 extends obliquely upwards towards the front side of the box body 10, so that the upper air outlet 19 can blow out hot air towards the upper front side of the box body 10, thereby drying the upper half area of the clothes.

[0050] In order to facilitate the communication setting between the first air outlet part 32 and the top air collecting cavity, in the embodiment of the present invention, an upper air duct cover 17 is provided in the accommodating cavity. The upper air duct cover 17 and the rear cover 12 of the box body 10 together define an upper air duct cavity. An upper air duct opening 18 for communicating the top air collecting cavity and the upper air duct cavity is penetrated and opened on the rear side of the box body 10. The first air outlet part 32 is communicated with the upper air duct cavity. In this way, in the embodiment of the present invention, by providing the upper air duct cover 17 in the accommodating cavity, the first air outlet part 32 of the fan assembly 24 can be flexibly arranged in the accommodating cavity, and through the communication setting between the first air inlet part and the upper air duct cavity, the hot air sent out from the first air outlet part 32 can pass through the upper air duct cavity, the top air collecting cavity and be blown out from the upper air outlet 19.

[0051] In addition, a lower air collecting cavity is defined below the front side of the box body 10 of the embodiment of the present invention. A lower air outlet 37 is penetrated and opened above the lower air collecting cavity. The second air outlet part 33 is communicated with the lower air collecting cavity. The positions of the lower air outlets 37 are all lower than the positions of the upper air outlet 19 and the air return part 13. Thus, in the present invention, by defining a lower air collecting cavity below the front side of the box body 10, the hot air sent out from the second air outlet part 33 can be better collected through the lower air collecting cavity and sent out through the lower air outlet 37 to dry the lower half area of the clothes; that is to say, in the present invention, two hot air flows with different heights can be sent out respectively through the lower air outlet 37 below the front side of the box body 10 and the upper air outlet 19 above the top of the box body 10, and the upper half area and the lower half area of the clothes can be dried respectively, thereby greatly improving the drying efficiency of the clothes.

[0052] Such as Figure 2 、 Figure 3 and Figure 5As shown, in the embodiment of the present invention, a lower air collecting box 36 is provided below the front side of the box body 10. An inner part of the lower air collecting box 36 defines a lower air collecting cavity. A lower air guiding opening 40 for communicating the second air outlet part 33 and the lower air collecting cavity is provided on one side of the lower air collecting box 36 connected to the box body 10. In this way, in the embodiment of the present invention, the lower air collecting box 36 is connected to the lower front side of the box body 10, an inner part of the lower air collecting box 36 defines a lower air collecting cavity, and the second air outlet part 33 and the lower air collecting cavity are communicated through the lower air guiding opening 40, so that the hot air sent out by the second air outlet part 33 can enter the lower air collecting cavity and be sent out through the lower air outlet 37.

[0053] As Figure 5 and Figure 9 As shown, a stepping motor 38 and a rotary air nozzle 39 are arranged inside the lower air collecting cavity. The stepping motor 38 is drivingly connected to the rotary air nozzle 39 and is used to drive the rotary air nozzle 39 to rotate. The rotary air nozzle 39 is located below the lower air outlet 37. In this way, in the embodiment of the present invention, the stepping motor 38 is arranged inside the lower air collecting cavity, so as to drive the rotary air nozzle 39 to rotate through the stepping motor 38. The air flow blown out from the air outlet can be sent out at different angles after swinging through the rotary air nozzle 39, so as to achieve the effect of automatically adjustable air outlet angle and make the drying process more uniform.

[0054] That is to say, the box body 10 of the embodiment of the present invention defines an accommodation cavity inside for installing a dehumidification component and a fan component 24. The rear side of the box body 10 and the upper air collecting cover 16 together define an upper air collecting cavity with an upper air outlet 19 provided above. The lower front side of the box body 10 and the air collecting box 36 together define a lower air collecting cavity. Inside the accommodation cavity, under the action of the fan component 24, the air above the front side of the box body 10 enters the inside of the accommodation cavity from the air return part 13, and after being dried and heated by the dehumidification component, the dry hot air is respectively sent into the upper air collecting cavity and the lower air collecting cavity through the first air outlet part 32 and the second air outlet part 33 of the fan component 24, and finally blown out through the upper air outlet 19 and the lower air outlet 37 respectively, so as to achieve the effect of drying the upper half area and the lower half area of the clothes, and greatly improve the drying efficiency of the clothes.

[0055] As Figures 10 to 13As shown in the figure, the air flow path of the dehumidifying and drying device according to the embodiment of the present invention is as follows: Moist air enters the accommodation cavity from the first air return opening 14 at the top of the box body 10 and the second air return opening 15 above the front side of the box body 10. After passing through the evaporator 20, the water vapor in the moist air is condensed into water droplets and drips into the water receiving tray 21. The dry air coming out of the evaporator 20 enters the condenser 22, and is heated under the action of the condenser 22 to form dry hot air. After the dry hot air comes out of the condenser 22, it enters the first volute 28 and the second volute 30 respectively, and then the dry hot air is sent into the upper air collecting cavity and the lower air collecting cavity through the first air outlet part 32 and the second air outlet part 33 respectively. The hot air in the upper air collecting cavity is blown out from the upper air outlet 19 to perform the drying operation on the upper half area of the clothes; the hot air in the lower air collecting cavity can make the dry hot air blow out in different directions from the lower air outlet 37 after passing through the rotating air nozzle 39 under the action of the stepping motor 38 driving the rotating air nozzle 39 to rotate, so as to perform the drying operation on the lower half area of the clothes.

[0056] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation on the scope of the dehumidifying and drying device of the invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
