[0106] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0107] Combine the following Figures 1 to 35 , describing the embodiments of the main device and drying equipment of the present invention.

[0108] According to an embodiment of the present invention, on the one hand, a main device is provided, which is used for drying equipment. The main device includes a base 1 and a shell assembly. The shell assembly is slidably arranged on the base 1 through a track assembly to increase or decrease the horizontal projection area of ​​the main device. When the shell assembly is folded on the base 1, the main device is in a folded state. When the shell assembly slides in a direction away from the base 1, the main device is in an unfolded state.

[0109] This main device can be applied to drying equipment, such as a clothes dryer. The shell assembly is slidably arranged on the base through a track assembly, so that the main device has a folded state and an unfolded state. The main device can be unfolded or folded according to usage needs to adapt to diverse usage needs, which can greatly enhance the use value of the drying equipment and improve the user experience.

[0110] The shell components can be provided in one group, wherein one group of shell components and the base form a two-stage foldable and unfoldable main device structure, or the shell components can be provided in two groups, wherein the two groups of shell components and the base form a three-stage foldable and unfoldable main device structure.

[0111] In this embodiment, two groups of shell components are provided, that is, the shell components include a first shell component and a second shell component, wherein the first shell component and the second shell component are slidably arranged on the base 1, and when the first shell component and the second shell component slide relative to each other to minimize the horizontal projection area of ​​the main device, the main device is in a folded state of the main device, and when the first shell component and the second shell component slide away from each other, the main device is in an unfolded state of the main device.

[0112] This shell assembly, the first shell assembly and the second shell assembly can slide relative to the base to form a three-section foldable and unfoldable main device structure. This main device structure is symmetrical, beautiful, and convenient for structural arrangement. It can be unfolded or folded according to usage needs to achieve changes in the size of the main device to meet diverse usage needs, achieve multi-purpose use of one machine, improve user experience, and the state switching process is simple and easy to operate.

[0113] Furthermore, the first shell assembly includes a first outer shell 3 and a first middle shell 4 connected to each other, and the second shell assembly includes a second outer shell 5 and a second middle shell 6 connected to each other. The first shell assembly and the second shell assembly have simple structures and are easy to install and connect.

[0114] like Figure 1-Figure 3 As shown, the base 1 is located at the lower part of the drying device, and structural components such as the air duct component 12, the heating element 13, the display component 14 and the controller component 15 are arranged on the base 1. The arrangement mode and function of the above-mentioned display component 14 and the controller component 15 are the same as those of the existing drying device, so they are not repeated here.

[0115] The upper surface of the base 1 is also provided with a base middle shell 11, which is used to shield structures such as the air duct component 12, the heating element 13, the display component 14, and the controller component 15 to protect these structures. The base middle shell 11 is detachably connected to the base 1, for example, by bolts. After installation, the base middle shell 11 and the bottom 1 are relatively stationary.

[0116] The first shell assembly includes a first outer shell 3 and a first middle shell 4 connected to each other, and the second shell assembly includes a second outer shell 5 and a second middle shell 6 connected to each other. The first outer shell 3 matches the second outer shell 5 in shape and size. When the main device is in a folded state, the first outer shell 3 is opposite to the second outer shell 5, and correspondingly, the first middle shell 4 and the second middle shell 6 are matched in shape and size. When the main device is in a folded state, the first middle shell 4 and the second middle shell 6 are opposite to each other.

[0117] Specifically, the first outer shell 3 and the second outer shell 5 are opposite to each other to form a box-shaped outer shell with a certain depth and no top surface, and the base 1 is arranged in the outer shell formed by the first outer shell 3 and the second outer shell 5. The first middle shell 4 is connected to the top of the first outer shell 3, and the second middle shell 6 is connected to the top of the second outer shell 5. The first middle shell 4 and the second middle shell 6 together form the top surface of the outer shell. After assembly, the first middle shell 4 and the second middle shell 6 are located above the base middle shell 11. In other words, the first outer shell 3, the second outer shell 5, the first middle shell 4 and the second middle shell 6 together form a complete box-shaped outer shell, and the box-shaped outer shell is sleeved on the outside of the base 1 and the base middle shell 11.

[0118] By pulling out the first shell assembly and the second shell assembly, the first shell assembly and the second shell assembly can slide relative to the base 1. When the first shell assembly and the second shell assembly slide relative to each other to minimize the horizontal projection area of ​​the main device, the main device is in a folded state. At this time, the size of the main device and the capacity of the corresponding drying equipment are also minimized; when the first shell assembly and the second shell assembly slide away from each other, the main device is in an unfolded state. At this time, the size of the main device gradually increases, and the capacity of the corresponding drying equipment also gradually increases, until the first shell assembly and the second shell assembly slide away from each other to the farthest position, the size of the main device is maximized, and the capacity of the corresponding drying equipment is also maximized.

[0119] In this embodiment, the sliding direction of the first shell assembly and the second shell assembly is the length direction of the base 1 (the length direction of the drying device), that is, Figure 1 The left and right direction in .

[0120] Further, the track assembly includes a first guide rail assembly 8 and a second guide rail assembly 9 arranged in parallel, the first guide rail assembly 8 is arranged between the first housing assembly and the base 1, and the second guide rail assembly 9 is arranged between the second housing assembly and the base 1. That is, the first housing assembly is slidably arranged on the base 1 through the first guide rail assembly 8, and the second housing assembly is slidably arranged on the base 1 through the second guide rail assembly 9.

[0121] In this embodiment, the arrangement direction of the first guide rail assembly 8 and the second guide rail assembly 9 is the length direction of the base 1 , that is, the sliding direction of the first shell assembly and the second shell assembly relative to the base 1 .

[0122] like Figure 4-Figure 18As shown, the first rail assembly 8 includes a first inner rail 801 and a first outer rail 802, the first inner rail 801 connects one of the first housing assembly and the base 1, and the first outer rail 802 connects the other; the second rail assembly 9 includes a second inner rail 901 and a second outer rail 902, the second inner rail 901 connects one of the second housing assembly and the base 1, and the second outer rail 902 connects the other. The first inner rail 801 can slide relative to the first outer rail 802, and the second inner rail 901 can slide relative to the second outer rail 902.

[0123] The movement strokes of the first rail assembly 8 and the second rail assembly 9 are both L1, that is, the maximum lengths that the first shell assembly and the second shell assembly can slide relative to the base 1 are both L1. Ideally, when the main device is folded, the distance between the first shell assembly and the second shell assembly at the closest position is 0 (the horizontal projection area of ​​the main device is the smallest at this time); when the main device is unfolded, the distance between the first shell assembly and the second shell assembly gradually increases until the distance between the two at the farthest position is 2L1.

[0124] In this embodiment, the first outer rail 802 and the second outer rail 902 are arranged at the bottom of the base 1, the first inner rail 801 is arranged on the bottom surface of the first shell 3 facing the base 1, and the second inner rail 901 is arranged on the bottom surface of the second shell 5 facing the base 1.

[0125] In other embodiments, the first inner rail 801 and the second inner rail 901 can be arranged at the bottom of the base 1, the first outer rail 802 can be arranged on the bottom surface of the first outer shell 3 facing the base 1, and the second outer rail 902 can be arranged on the bottom surface of the second outer shell 5 facing the base 1, which can also achieve the purpose of sliding the first shell assembly and the second shell assembly relative to the base 1.

[0126] In order to make the sliding process of the first shell assembly and the second shell assembly smoother, a first bead nest assembly 803 is arranged between the first inner rail 801 and the first outer rail 802 , and a second bead nest assembly 903 is arranged between the second inner rail 901 and the second outer rail 902 .

[0127] Taking the first guide rail assembly 8 as an example, the first inner rail 801 and the first outer rail 802 are both U-shaped rails, the first inner rail 801 is inverted inside the first outer rail 802, and a first bead nest assembly 803 consisting of a first bead rack 8031 ​​and a first steel ball 8032 is disposed between the first inner rail 801 and the first outer rail 802. Similarly, the second inner rail 901 and the second outer rail 902 are both U-shaped rails, the second inner rail 901 is inverted inside the second outer rail 902, and a second bead nest assembly 903 consisting of a second bead rack 9031 and a second steel ball 9032 is disposed between the second inner rail 901 and the second outer rail 902.

[0128] Furthermore, the spacing a between the bottom of the base 1 and the bottom surface of the first shell 3 facing the base 1, and between the bottom surface of the second shell 5 facing the base 1 is 0<a<5.6mm. In this embodiment, a is 4mm. If the above spacing a is 0, there will be movement friction between the first shell 3, the second shell 5 and the base 1, which will make the sliding of the first shell 3 and the second shell 5 not smooth, affecting the pulling and pulling of the first shell assembly and the second shell assembly. If the above spacing a is greater than or equal to 5.6mm, there is a possibility that the baby's test finger can be inserted into the body, causing pinching or electrical safety problems. At the same time, if the spacing a is too large, it will also affect the appearance of the dryer.

[0129] Furthermore, the main device of this embodiment also includes a locking mechanism, which is arranged between the first shell component and the second shell component, and is used to lock or unlock the position of the first shell component and the second shell component when the main device is in a folded state.

[0130] When the main device is in the folded state, the first shell assembly and the second shell assembly can be locked by a locking mechanism to form a position constraint on the first shell assembly and to prevent the first shell assembly and the second shell assembly from sliding arbitrarily relative to the base during the movement of the main device, thereby affecting the movement of the main device.

[0131] like Figure 19-Figure 23 As shown, further, the locking mechanism is arranged between the first middle shell 4 and the second middle shell 6. Since there are fewer parts on the first middle shell 4 and the second middle shell 6, the structural space is larger, which is convenient for the arrangement of the locking mechanism.

[0132] Furthermore, the locking mechanism includes at least one set of buckled locks 701 and lock tongues 702, wherein the locks 701 are arranged on one of the first middle shell 4 and the second middle shell 6, and the lock tongues 702 are arranged on the other one.

[0133] In this embodiment, the locking mechanism includes a set of buckle 701 and lock tongue 702 that are buckled and connected, the buckle 701 is arranged on the first middle shell 4, and the lock tongue 702 is arranged on the second middle shell 6. Further, the first middle shell 4 and the second middle shell 6 are provided with corresponding locking grooves 703, specifically, the locking groove 703 is arranged on the upper surface of the first middle shell 4 and the second middle shell 6, and the locking groove 703 is recessed downward from the upper surface of the first middle shell 4 and the second middle shell 6. One end of the buckle 701 is rotatably connected to the side wall of the locking groove 703, and the lock tongue 702 is arranged at the bottom of the locking groove 703.

[0134] Specifically, a rotating shaft 7011 is provided at one end of the lock buckle 701, and the axial direction of the rotating shaft 7011 is perpendicular to the length direction of the locking groove 703. The rotating shaft 7011 protrudes from both sides of the lock buckle 701, and a rotating shaft hole 7031 is provided at the corresponding position of the side wall of the locking groove 703. The rotating shaft 7011 is suitable for being inserted into the rotating shaft hole 7031, and the rotating shaft 7011 can rotate in the rotating shaft hole 7031, so as to realize the change of the groove bottom angle between the lock buckle 701 and the locking groove 703 from 0° to 180°.

[0135] In this embodiment, the lock buckle 701 is arranged in the locking groove 703 of the first middle shell 4, and an assembly opening is opened in the middle of the lock buckle 701, and a boss 7012 is arranged on the side of the assembly opening. In this embodiment, a boss 7012 is arranged on the side of the assembly opening close to the second middle shell 6, and the lock tongue 702 is arranged in the locking groove 703 of the second middle shell 6. The boss 7012 is suitable for snap-fitting with the lock tongue 702 to achieve locking of the first middle shell 4 and the second middle shell 6.

[0136] When the main device is folded, the lock buckle 701 is operated to rotate toward the second middle shell 6 until the boss 7012 is engaged with the lock tongue 702. At this time, the first middle shell 4 and the second middle shell 6 are locked, and the main device can be moved. When the first shell assembly and the second shell assembly need to be pulled out, the lock buckle 701 is first operated to rotate away from the second middle shell 6 to disengage the boss 7012 from the lock tongue 702. At this time, the first middle shell 4 and the second middle shell 6 are unlocked, and the first shell assembly and the second shell assembly can be pulled out.

[0137] In other embodiments, the locking mechanism may also include two or three groups of buckled locks 701 and lock tongues 702. The specific number of groups may be selected according to the size of the main device.

[0138] like Figure 24-28 As shown, on the base 1, the air duct assembly 12 includes a centrifugal air duct 17, an inner air duct 18 and an air outlet air duct 19 which are connected in sequence.

[0139] The centrifugal air duct 17 is formed by a first volute 1701 and a second volute 1702. The first volute 1701 is set on a base 1703. One side of the second volute 1702 is rotatably connected to the base 1703. The other side of the second volute 1702 is detachably connected to the first volute 1701. The base 1703 is set in the base 1.

[0140] The inner air duct 18 is formed inside the first volute 1701, a first limiting rib 1801 is provided inside the inner air duct 18, a second limiting rib 1904 is provided inside the air outlet duct 19, and the first limiting rib 1801 and the second limiting rib 1904 define the installation space of the heating element 13. In addition, a temperature limiter is also provided at the joint of the air outlet duct 19 and the inner air duct 18.

[0141] The outlet duct 19 has an upwardly bent outlet 1903 at one end away from the centrifugal duct 17, and the outlet 1903 is arranged upward to form a U-shaped outlet duct, and an outlet grille 1905 is arranged at the outlet 1903. The outlet duct 19 includes a first duct plate 1901 and a second duct plate 1902, the first duct plate 1901 is arranged on the base 1703, and the second duct plate 1902 is detachably connected to the first duct plate 1901 and forms an inner cavity of the outlet duct 19. In this embodiment, the second duct plate 1902 is connected to the first duct plate 1901 by a buckle 20.

[0142] like Figure 29-35 As shown, this embodiment also provides a drying device, including the main device of the above embodiment. This drying device can change the capacity of the drying space as the main device is folded and unfolded to meet different usage requirements and facilitate storage.

[0143] Furthermore, in this embodiment, the drying device is a clothes dryer, and the clothes dryer also includes a hanger assembly, and the hanger assembly includes a clothes rod assembly and a folding clothes hanger 2, and one end of the clothes rod assembly is connected to the base 1 or one end of the clothes rod assembly is connected to the housing assembly. In this embodiment, one end of the clothes rod assembly is connected to the housing assembly, specifically, one end of the clothes rod assembly is connected to the first housing assembly or the second housing assembly, and the folding clothes hanger 2 is arranged at the other end of the clothes rod assembly, and the folding clothes hanger 2 has a clothes hanger folded state corresponding to the folded state of the main device and a clothes hanger unfolded state corresponding to the unfolded state of the main device.

[0144] Since the main device has a folded state and an unfolded state, and the folding hanger has a folded state corresponding to the folded state of the main device and an unfolded state corresponding to the unfolded state of the main device, the dryer has a folded state and an unfolded state. The dryer can be unfolded or folded according to the use needs, so as to change the size of the dryer, that is, to change the capacity of the dryer. The user can choose the use state of the dryer according to the needs. When there are fewer clothes to be dried, the dryer can be in the folded state, at which time the dryer volume is the smallest. When there are more clothes to be dried, the dryer can be in the unfolded state, at which time the dryer volume is the largest, so as to meet the diverse use needs and improve the user experience. At the same time, when the dryer is not needed, the dryer can be folded to reduce its volume and occupied space, so as to facilitate the user to store it.

[0145] Furthermore, the folding hanger 2 includes a fixed hanger and a movable hanger. The movable hanger is telescopically arranged on the fixed hanger, and the telescopic direction of the movable hanger is consistent with the sliding direction of the shell assembly.

[0146] In this embodiment, the folding hanger 2 is a plate-like structure as a whole, and the folding hanger 2 includes an intermediate frame 201, a first hanger 202 and a second hanger 203. The intermediate frame 201 is a fixed hanger, and the first hanger 202 and the second hanger 203 are movable hangers. The first hanger 202 and the second hanger 203 are respectively telescopically arranged at both ends of the intermediate frame 201, and the telescopic direction of the first hanger 202 is consistent with the sliding direction of the first shell assembly, and the telescopic direction of the second hanger 203 is consistent with the sliding direction of the second shell assembly.

[0147] like Figure 24-26 As shown, the size of the folding hanger 2 matches the size of the first shell component and the second shell component. In order to adapt to the change in the size of the dryer, the folding hanger 2 has a hanger folded state corresponding to the folded state of the main device and a hanger unfolded state corresponding to the unfolded state of the main device.

[0148] Specifically, a slide rail 206 is provided on the side of the first hanger 202 and the second hanger 203 facing the base 1 or the side away from the base 1. In this embodiment, three slide rails 206 are provided, and the extension direction of the slide rails 206 is consistent with the sliding direction of the first shell assembly and the second shell assembly. Both ends of the middle frame 201 are provided with protrusions 205, and the number of the protrusions 205 is less than or equal to the number of the slide rails 206. In this embodiment, three protrusions 205 are also provided, and the protrusions 205 are suitable for inserting into the slide rails 206, and the protrusions 205 can slide in the slide rails 206 to achieve the sliding of the first hanger 202 and the second hanger 203 relative to the middle frame 202. The distance that the first hanger 202 slides outward relative to the middle frame 202 is L1, and similarly, the distance that the second hanger 203 slides outward relative to the middle frame 202 is also L1, that is, the sliding stroke of the first hanger 202 is the same as that of the first shell assembly, and the sliding stroke of the second hanger 204 is the same as that of the second shell assembly.

[0149] In other embodiments, the number of the slide rails 206 may be one, two, etc., and may be selected according to usage requirements.

[0150] Furthermore, a plurality of sockets 204 are provided on the sides of the first hanger 202 and the second hanger 203 facing the base 1 . In this embodiment, two sockets 204 are provided on the first hanger 202 and the second hanger 203 , respectively, that is, the folding hanger 2 is provided with four sockets 204 .

[0151] Furthermore, the clothes rod assembly includes four telescopic rods 10, two of which are arranged at corners of the upper surface of the first shell assembly at intervals, and the other two telescopic rods 10 are arranged at corners of the upper surface of the second shell assembly at intervals.

[0152] like Figure 27-Figure 28As shown, the telescopic rod 10 is arranged perpendicular to the upper surface of the base 1, and the telescopic rod 10 can be extended or shortened along its axial direction to achieve the change of the height size of the dryer. The lower end of the telescopic rod 10 is arranged at the four corners of the dryer. Specifically, two of the telescopic rods 10 are arranged at the two corners of the upper surface of the first middle shell 4, and the other two telescopic rods 10 are arranged at the two corners of the upper surface of the second middle shell 6. After the telescopic rod 10 is connected to the first shell assembly and the second shell assembly, it is relatively stationary. The upper end of the telescopic rod 10 is plugged into the socket 204 to realize the assembly of the clothes rod assembly and the folding hanger 2.

[0153] Furthermore, the clothes dryer of this embodiment further comprises a clothes cover 16, which is disposed on the outside of the hanger assembly. The clothes cover 16 has a clothes cover folded state that matches the folded state of the main device, and a clothes cover unfolded state that matches the unfolded state of the main device.

[0154] like Figure 29-Figure 30 As shown, in this embodiment, the clothing cover 16 is in the shape of a cuboid, with no cloth on the bottom and cloth on the other five surfaces. In order to adapt to the size changes of the main device in different states, the clothing cover 16 has a folded state that matches the folded state of the main device, and an unfolded state that matches the unfolded state of the main device.

[0155] Specifically, the front of the clothing cover 16 is provided with a front zipper 1601. When the front zipper 1601 is opened, the user can take the clothes. The front zipper 1601 is preferably a T-shaped zipper. The clothing cover 16 is also provided with a side zipper 1602. The side zipper 1602 is a U-shaped zipper that runs through the front, top and back of the clothing cover 16. When the side zipper 1602 is opened, the size of the clothing cover 16 along the length direction of the base 1 can be increased to adapt to the size changes of the main device in different states.

[0156] When the side zipper 1602 is closed, the length dimension of the garment cover 16 is L3. When the side zipper 1602 is opened, the length dimension of the garment cover 16 is L2+L3, and L2=L1+L1.

[0157] When the main device is in the folded state, the side zipper 1602 is in the closed state, and the size of the clothing cover 16 is at its smallest to match the state when the dryer is at its smallest length. When the main device is in the unfolded state, the side zipper 1602 is opened to make the size of the clothing cover 16 become the largest to match the state when the dryer is at its largest length. The clothing cover 16 can be adjusted according to the folded or unfolded state of the main device to adapt to the length of the main device in both the folded state and the unfolded state, which has strong applicability and improves the drying effect.

[0158] The assembly process of the clothes dryer of this embodiment is described below:

[0159] First, the air duct assembly 12, the heating element 13, the display assembly 14, the controller assembly 15, etc. are arranged on the base 1;

[0160] Install the first outer rail 802 and the second outer rail 902 at the bottom of the base 1, install the first inner rail 801 on the bottom surface of the first shell 3 facing the base 1, and install the second inner rail 901 on the bottom surface of the second shell 5 facing the base 1, ensuring that the first inner rail 801 and the first outer rail 802 can slide relative to each other, and ensuring that the second inner rail 901 and the second outer rail 902 can slide relative to each other, and now the assembly of the first shell 3, the second shell 5 and the base 1 is completed;

[0161] Afterwards, a base middle shell 11 is installed on the upper part of the base 1 to protect the relevant structure;

[0162] Then, the first middle shell 4 is installed with the first outer shell 3, and the second middle shell 6 is installed with the second outer shell 5. The first middle shell 4 and the first outer shell 3 form a first shell assembly, and the second middle shell 6 and the second outer shell 5 form a second shell assembly;

[0163] Finally, the telescopic rod 10 is inserted into the four corners of the dryer, the folding hanger 2 is plugged into the top of the telescopic rod 10, and a clothes cover 16 is provided on the outside of the hanger assembly, thereby completing the assembly of the dryer.

[0164] In order to further understand the clothes dryer of this embodiment, the working process of the clothes dryer of this embodiment is described below in conjunction with the accompanying drawings:

[0165] When using the dryer for drying, if the amount of clothes is small and there is no need to change the length of the entire machine, the first shell assembly and the second shell assembly are closest to each other (even when the horizontal projection area of ​​the main device is the smallest). At this time, the main device is in a folded state (that is, the dryer is in a folded state). The height of the telescopic rod 10 can be selected according to the height of the clothes to be dried, and the clothes can be taken through the front zipper 1601 to dry the clothes.

[0166] If the number of clothes is large and the length of the dryer needs to be changed, the first shell assembly and the second shell assembly are pulled out to slide back to back, the main device is unfolded, and the first hanger 202 and the second hanger 203 of the folding hanger 2 are pulled out simultaneously to put the folding hanger in the unfolded state, and the side zipper 1602 of the clothing cover 16 is opened to put the clothing cover in the unfolded state, and the clothes can be dried.

[0167] When the clothes dryer is stored, the main device is in the folded state, and the lock buckle 701 is rotated 180° toward the second middle shell 6 so that the boss 7012 is engaged with the lock tongue 702. At this time, the first middle shell 4 and the second middle shell 6 are locked, that is, the first shell assembly and the second shell assembly are locked and will not slide relative to the base 1. At this time, the clothes dryer can be moved and stored.

[0168] like Figure 36-42 FIG. 1 is a main device structure of another embodiment of the present invention, which is different from the main device of the previous embodiment in that the main device of this embodiment further includes:

[0169] The heating air duct mechanism is arranged on the base 1, and the heating air duct mechanism includes an air duct inlet and an air duct outlet, and the air duct outlet is connected to the drying area of ​​the drying device. The heating air duct mechanism is used to heat the air and provide dry hot air to the drying area to dry the items. The heating air duct mechanism also includes a heating element 13. The air entering the heating air duct mechanism from the air duct inlet is heated by the heating element 13 to become hot air, and the hot air is discharged from the air duct outlet to the drying area. In this embodiment, the drying device is a clothes dryer.

[0170] The shell assembly includes a first shell assembly and a second shell assembly. At least one of the first shell assembly and the second shell assembly is provided with a shell air inlet, which connects the external air and the air duct inlet. At least one of the first shell assembly and the second shell assembly is provided with a shell return air inlet, which connects the air duct inlet and the drying area.

[0171] External air enters the duct inlet from the shell inlet, and the air is heated in the heating duct mechanism to form hot air, which is blown out from the duct outlet to the drying area to dry the items. The hot air in the drying area can also flow back to the duct inlet through the shell return air port, increasing the temperature of the air at the duct inlet, reducing the heat energy required to heat the air, improving the air heating efficiency, and increasing the outlet temperature, increasing the air intake, outlet volume, outlet speed and air supply distance of the heating duct mechanism, accelerating the drying speed, shortening the drying time, and providing a better user experience.

[0172] Furthermore, the base 1 includes a base air inlet 101, the shell air inlet is connected to the air duct air inlet through the base air inlet 101, and the air inlet area of ​​the shell air inlet is larger than the air inlet area of ​​the base air inlet 101. By making the air inlet area of ​​the shell air inlet larger than the air inlet area of ​​the base air inlet, the air inlet volume of the external air entering the main device can be increased, thereby increasing the air outlet volume and accelerating the drying speed. Preferably, the air inlet area of ​​the shell air inlet is at least twice the air inlet area of ​​the base air inlet 101.

[0173] The base 1 also includes a base air outlet 102 , which is connected to the air outlet of the air duct, and the hot air is blown toward the drying area through the air outlet of the air duct and the base air outlet 102 .

[0174] Furthermore, the air duct inlet includes a first air duct inlet 1201 and a second air duct inlet 1202, the first shell assembly is provided with a first shell air inlet 301 and a first shell return air outlet 401, the second shell assembly is provided with a second shell air inlet 501 and a second shell return air outlet 601, the first air duct inlet 1201 is connected with the first shell air inlet 301 and the first shell return air outlet 401, and the second air duct inlet 1202 is connected with the second shell air inlet 501 and the second shell return air outlet 601.

[0175] Specifically, the heating air duct mechanism includes a first air duct 1207 and a second air duct 1208. The first air duct 1207 is formed by a first volute 1203. The first air duct 1207 is a straight air duct. The first air duct 1207 has two first air duct air inlets 1201 at both ends, that is, the first air duct air inlet 1201 is set to two, and a first centrifugal wind wheel 1205 is arranged in the first air duct 1207. The second air duct 1208 is formed by a second volute 1204. The second air duct 1208 is a straight air duct. The second air duct 1202 is set to two second air duct air inlets 1202 at both ends, that is, the second air duct air inlet 1202 is set to two, and a second centrifugal wind wheel 1206 is arranged in the second air duct 1208. The first centrifugal wind wheel 1205 and the second centrifugal wind wheel 1206 are respectively connected to the two driving shafts of the dual-axis motor 21, and the dual-axis motor 21 can simultaneously drive the first centrifugal wind wheel 1205 and the second centrifugal wind wheel 1206 to rotate.

[0176] Furthermore, there are four base air inlets 101, two of which are arranged near the first air duct air inlet 1201, and the other two base air inlets 101 are arranged near the second air duct air inlet 1202. The first shell air inlet 301 is located below the two base air inlets 101 arranged near the first air duct air inlet 1201, and the second shell air inlet 501 is located below the two base air inlets 101 arranged near the second air duct air inlet 1202.

[0177] Specifically, the first air duct air inlet 1201 is arranged at both ends of the first air duct 1207, and there are two of them. The two base air inlets 101 are respectively arranged close to the two first air duct air inlets 1201. Similarly, the second air duct air inlet 1202 is arranged at both ends of the second air duct 1208, and there are two of them. The other two base air inlets 101 are respectively arranged close to the two second air duct air inlets 1202.

[0178] The first shell assembly includes a first outer shell 3 and a first middle shell 4 connected to each other, the first shell air inlet 301 is arranged on the first outer shell 3, and the first shell air return port 401 is arranged on the first middle shell 4. In this embodiment, the first shell air return port 401 is located above the first shell air inlet 301, and the air inlet area of ​​the first shell air return port 401 is smaller than the air inlet area of ​​the first shell air inlet 301.

[0179] The second shell assembly includes a second outer shell 5 and a second middle shell 6 connected to each other, the second shell air inlet 501 is arranged on the second outer shell 5, and the second shell air return port 601 is arranged on the second middle shell 6. In this embodiment, the second shell air return port 601 is located above the second shell air inlet 501, and the air inlet area of ​​the second shell air return port 601 is smaller than the air inlet area of ​​the second shell air inlet 501.

[0180] like Fig.42 As shown, arrow A indicates the direction in which external air enters the main device, arrow B indicates the direction in which hot air is blown out of the main device, and arrow C indicates the direction in which hot air from the drying area enters the main device. It can be seen that external air can enter the air duct through the shell air inlet, the base air inlet 101, and the air duct air inlet in sequence, and is heated into hot air under the action of the heating element 13. The hot air is blown to the drying area through the air duct outlet, and the hot air in the drying area can also enter the air duct through the shell return air port and the air duct air inlet in sequence, forming an air flow cycle.

[0181] When the main device is in the folded state, a portion of the first shell air inlet 301 and the second shell air inlet 501 are folded at a position at the bottom of the base 1 where the base air inlet 101 is not provided, resulting in a portion of the first shell air inlet 301 and the second shell air inlet 501 being blocked, and the effective air inlet area of ​​the first shell air inlet 301 and the second shell air inlet 501 is reduced, which is suitable for use when there are fewer clothes to be dried.

[0182] When the main device is in the unfolded state, the first shell air inlet 301 and the second shell air inlet 501 are pulled out from the bottom of the base 1, and the first shell air inlet 301 and the second shell air inlet 501 are no longer blocked. The effective air inlet area of ​​the first shell air inlet 301 and the second shell air inlet 501 is increased, which is suitable for use when there are many clothes to be dried.

[0183] When drying clothes, the dual-axis motor 21 drives the first centrifugal fan wheel 1205 and the second centrifugal fan wheel 1206 to rotate. Under the action of negative pressure, external air enters the dryer from the first shell air inlet 301 and the second shell air inlet 501, and then enters the first air duct air inlet 1201 and the second air duct air inlet 1202 through the base air inlet 101. In the first air duct 1207 and the second air duct 1208, the air is heated into hot air, and the hot air will be blown from the air duct outlet through the base air outlet 102 to the drying area to dry the clothes. The hot air in the drying area can also enter the first air duct air inlet 1201 and the second air duct air inlet 1202 through the first shell return air inlet 401 and the second shell return air inlet 601, forming an air flow cycle, which can increase the air flow temperature out of the air inlet, save heat energy, and improve the drying efficiency.

[0184] According to experimental calculations, compared with a clothes dryer without a housing return air outlet, the air volume at the air duct outlet of the clothes dryer in this embodiment can be increased by 5m 3 / h, and drying the same 12 pieces of clothing, the drying time of the clothes dryer in this embodiment is shortened by 10 minutes.

[0185] In other embodiments, the housing assembly may be provided in a group, and a group of housing assemblies and the base form a two-stage foldable main device structure. In this case, the track assembly includes an inner track and an outer track, the inner track connects one of the base 1 and the housing assembly, and the outer track connects the other.

[0186] Optionally, the base 1 is placed inside the housing assembly, the inner rail is arranged at the bottom of the base 1, and the outer rail is arranged at the bottom surface of the housing assembly facing the base 1. Of course, the outer rail can also be arranged at the bottom of the base 1, and the inner rail can be arranged at the bottom surface of the housing assembly facing the base 1.

[0187] The distance a between the bottom of the base 1 and the bottom surface of the shell assembly facing the base 1 is 0<a<5.6mm, and optionally a=3mm.

[0188] In order to make the inner rail and the outer rail slide more smoothly, a bead nest assembly is arranged between the inner rail and the outer rail.

[0189] Furthermore, it also includes a locking mechanism, which is arranged between the base 1 and the shell assembly. The locking mechanism is used to lock or unlock the position of the base 1 and the shell assembly when the main device is in a folded state, so that when the main device is moved, the shell assembly can slide arbitrarily and affect the movement of the main device.

[0190] The locking mechanism includes at least one set of buckled locks 701 and lock tongues 702, wherein the locks 701 are arranged on one of the base 1 and the housing assembly, and the lock tongues 702 are arranged on the other. Optionally, the locks 701 are arranged on the base 1, and the lock tongues 702 are arranged on the housing assembly. Of course, the locks 701 can also be arranged on the housing assembly, and the lock tongues 702 can be arranged on the base 1.

[0191] The above two-stage foldable and unfoldable main body device structure is relatively simple in structure, which is beneficial to reducing manufacturing costs and simplifying the user operation process.

[0192] When the main device is a two-stage foldable and unfoldable structure, the drying device is also a matching two-stage structure.
