Description

Technical Field

[0001] The present application relates to the technical field of clothes drying machines, and in particular to a drying device, a clothes drying rack and a clothes drying machine. Background Art

[0002] At present, the mainstream clothes drying machines on the market generally adopt a relatively basic way of expanding the drying space in design, that is, by adding a telescopic rod structure on the basis of the main drying rod to achieve the extension of the drying space. When users have a lot of clothes to dry, they only need to pull the telescopic rod out from the main drying rod to hang the extra clothes on the telescopic rod, which to a certain extent meets the basic needs of users to increase the number of clothes to be dried.

[0003] However, the extension length of the telescopic rod is strictly limited by the length of the main drying rod. The main drying rod is the main supporting structure of the clothes drying machine, and its length needs to be designed taking into account multiple factors, such as the size of the installation space and aesthetics. As a result, the length of the main drying rod is usually set within a relatively fixed range, which is difficult to adjust at will according to the user's growing drying needs.

[0057] To make the technical problems solved by this application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of this application will be further described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of this application.

[0058] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0059] In this application, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "below", and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the horizontal height of the first feature is lower than that of the second feature.

[0060] At present, the mainstream clothes drying machines on the market generally adopt a relatively basic way of expanding the drying space in design, that is, by adding a telescopic rod structure on the basis of the main drying rod to achieve the extension of the drying space. When users have a lot of clothes to dry, they only need to pull the telescopic rod out from the main drying rod to hang the extra clothes on the telescopic rod, which to a certain extent meets the basic needs of users to increase the number of clothes to be dried.

[0061] However, the extension length of the telescopic rod is strictly limited by the length of the main drying rod. The main drying rod is the main supporting structure of the clothes drying machine, and its length needs to be designed taking into account multiple factors, such as the size of the installation space and aesthetics. As a result, the length of the main drying rod is usually set within a relatively fixed range, which is difficult to adjust at will according to the user's growing drying needs.

[0062] Therefore, how to break through the bottleneck of existing clothes drying machines in expanding the drying space and develop a new type of clothes drying machine technology that can achieve a larger drying capacity in a limited space and meet the diverse drying needs of users has become a key issue that needs to be urgently resolved in the current clothes drying machine industry.

[0063] In order to overcome the above technical problems, the present embodiment provides a drying device, which can be installed at the end of the clothes drying rack of an existing clothes drying machine. The drying device has the function of being foldable and unfoldable. When it is necessary to expand the drying space, the drying device can be unfolded for use; when the drying rack is retracted, the drying device can be folded and stored. The stored drying device occupies little space and has little impact on the size of the existing clothes drying machine.

[0064] It should be noted that the drying device of the present solution can not only be used on clothes drying machines to expand the drying space of the clothes drying machines, but also be applied to other usage scenarios. For example, it can be installed on a wall for use alone, or installed on other equipment that needs to provide a drying function.

[0065] like Figures 1 - 17 As shown, this embodiment provides a drying device, comprising:

[0066] A first seat body 4 and a second seat body 5;

[0067] A folding arm 2, both ends of which are rotatably connected to the first seat body 4 and the second seat body 5;

[0068] A drying assembly 3 is installed on the first seat body 4 and the second seat body 5; or installed on the folding arm 2;

[0069] Among them, the folding arm 2 includes a rotating connector 22 and at least two swing arms 21. Any two adjacent swing arms 21 are rotatably connected through the rotating connector 22. The folding arm 2 is folded and unfolded by the mutual rotation between the swing arms 21. The rotating connector 22 includes a positioning structure, and the positioning structure can position the folding arm 2 in the unfolded state, so that the drying component 3 is unfolded between the first seat body and the second seat body to provide a drying support function. In the drying device of this embodiment, the provided drying component 3 serves as the main support carrier when drying clothes, and it can be, but is not limited to, a form of a drying net component, a form of a foldable drying basket component, or a form of a drying rod component with multiple small drying rods, etc.

[0070] In the structure of the folding arm 2, it includes at least two swing arms 21. Any two adjacent swing arms 21 are connected through a rotating connector 22, so that the swing arms 21 can rotate relative to each other for unfolding and folding (refer to the V-shaped or Z-shaped folding structure). Preferably, the angle at which the swing arms 21 can rotate relative to each other is 180°. When folding, referring to Figure 12 , the two swing arms 21 are arranged side by side, and the overall length is only the length of one swing arm 21. When unfolding, referring to Figure 9 , the two swing arms 21 are arranged in parallel, and the overall length is the length of the two swing arms 21. Moreover, the end of the swing arm 21 at the front end is rotatably connected to the first seat body 4, and the end of the swing arm 21 at the rear end is rotatably connected to the second seat body 5, so that the folded folding arm 2 can still be arranged side by side with the first seat body 4 and the second seat body 5, and finally the distance between the first seat body 4 and the second seat body 5 is minimized, realizing the most degree of folding and retracting of the entire drying device.

[0071] Among them, in the structure of the folding arm 2, the number of swing arms 21 can be reasonably selected according to requirements. When the number of swing arms 21 is even, during the folding and unfolding process, the axial direction of the hinge axis of the folding arm 2 with the first seat body 4 and the second seat body 5 is always in a plane. Therefore, the folding arm 2 only needs to be hinged to the first seat body 4 and the second seat body 5. When the number of swing arms 21 is odd, during the folding and unfolding process, the axial direction of the hinge axis of the folding arm 2 with the first seat body 4 and the second seat body 5 cannot always be in a plane. In addition to being rotatably connected, the folding arm 2 also needs to be able to slide relative to the first seat body 4 or the second seat body 5. For example, the folding arm 2 is rotatably and slidably connected to the second seat body 5.

[0072] The swing arms 21 are connected by a rotating connector 22. Optionally, the rotating connector 22 can adopt a hinge-like mechanical structure, which consists of two relatively rotatable components. The components are provided with shaft holes, and adjacent swing arms 21 are connected by a shaft pin to achieve relative rotation between the swing arms 21. This structure is simple and reliable, with low cost and is easy to process and install. In order to make the folding arm 2 more stable during the unfolding and folding processes, a damping structure can be added to the rotating connector 22. For example, a rubber washer or damping grease can be provided between the shaft pin and the shaft hole to control the rotation speed of the swing arm 21 by increasing the friction force, avoiding the situation that the swing arm 21 generates impact or instability due to too fast rotation.

[0073] The folding arm 2 plays a crucial role in the solution of this embodiment. After unfolding, it is used to support the second seat body 5. During application, the drying component 3 is installed on the second seat body 5 or the folding arm 2. Therefore, the stability of the folding arm 2 itself determines the stability of the drying component 3, that is, it affects the reliability of the drying function and the user's drying experience.

[0074] Since the folding arm 2 is a rotatable folding structure and itself has instability, in order to improve the stability performance after unfolding, in the solution of this embodiment, a positioning structure is arranged in the rotating connector 22 to stabilize the unfolded state of the folding arm 2. Optionally, the positioning structure can adopt the form of an elastic buckle. An elastic buckle is arranged on the rotating connector 22, and a corresponding card slot is arranged on the swing arm 21. When the folding arm 2 is unfolded to a certain angle, the elastic buckle will snap into the card slot to lock the folding arm 2 in the unfolded state. When unlocking, only need to apply a certain external force to overcome the elastic force of the elastic buckle to disengage the buckle from the card slot, so that the folding arm 2 can be folded. Another option is to use the magnetic force of a magnet for positioning. Magnets are respectively installed on the rotating connector 22 and the swing arm 21. When the folding arm 2 is unfolded to a suitable position, the magnets attract each other to fix the folding arm 2 in the unfolded state. This structure is simple, does not require a complex mechanical structure, and has reliable positioning. Another option is to adopt a ratchet and pawl mechanism as the positioning structure. The ratchet is fixed on the rotating connector 22, and the pawl is installed on the swing arm 21. When the folding arm 2 is unfolded, the pawl slides on the ratchet. When unfolded to the required position, the pawl snaps into the tooth groove of the ratchet to prevent the folding arm 2 from retracting. When unlocking, by operating the pawl to disengage it from the ratchet tooth groove, the folding of the folding arm 2 can be achieved.

[0075] Importantly, the drying device of this solution can be integrated into the drying rack of an existing drying machine, and has the advantages of good integrity and compactness after combination, and can effectively broaden the drying capacity of the drying rack. For the convenience of description, the structure of the existing drying rack and the combined effect are described here: combination Figure 18, existing drying racks are usually set in a square structure, which includes two parallel drying rods 7 in the front and back and two parallel support crossbeams 6 on the left and right. The two support crossbeams 6 are respectively connected between the ends of the two drying rods 7. The existence of the support crossbeams 6 makes the whole drying rack have the advantage of strong stability. In specific applications, when combining the drying device of this solution into a drying rack, the drying device can be used to replace the existing support crossbeam 6, that is, the two ends of the first seat body 4 of the drying device are respectively connected to the ends of the two drying rods 7. When the drying device is retracted, it has the same structure as the existing support crossbeam 6, so it has a high degree of integration with the drying rack and has little impact on the overall size change of the drying rack; when a larger drying space is needed, the drying assembly 3 can be unfolded for use. Or, the drying device can also be combined and installed on the support crossbeam 6 (the two can be directly connected or connected and fixed through other connecting parts). At this time, the drying device is highly integrated with the support crossbeam 6. On the basis of providing more drying space, it actually has little impact on the overall size change of the whole drying rack.

[0076] In summary, the drying device of this embodiment can at least achieve the following beneficial effects: Through the retractable and expandable design, the additional drying assembly 3 can be unfolded when needed, effectively expanding the drying space and meeting the diverse drying needs of users. Especially when there are more clothes to be dried, it can provide a larger drying capacity. Moreover, a positioning structure is provided in the folding arm 2, which can keep the unfolded drying device stable and provide more reliable drying support for users. During use, users only need to perform simple pulling and unlocking actions to realize the unfolding and recycling of the drying device, and the operation is simple, easy to understand, convenient and fast.

[0077] When combining the drying device of this solution into a clothes dryer, since the retracted drying device occupies little space and has little impact on the size of the existing clothes dryer, when installed on a drying rack, whether it replaces the support crossbeam 6 or is combined and installed on the support crossbeam 6, it can have a high degree of integration with the drying rack and will not cause a great impact on the overall structure and use of the drying rack. Moreover, when needed, it can effectively broaden the drying capacity of the clothes dryer and meet the more drying needs of users.

[0078] Regarding the feasible form of the drying assembly 3, in one embodiment, the drying assembly 3 is a drying net assembly, which includes a reel 31 and a drying net 32 wound around the reel 31. The reel 31 is connected to the first seat body 4, and the telescopic end of the drying net 32 is connected to the second seat body 5; through the folding and unfolding of the folding arm 2, the recycling and opening of the drying net assembly are realized;

[0079] Among them, a coil spring is provided inside the reel 31, which has the ability of self-retraction. When the external force is greater than the retraction ability of the reel 31, the external force can pull the sunshade net 32 to open; when the external force is less than the retraction ability of the coil spring, the reel 31 automatically rolls up the sunshade net 32.

[0080] When the drying device of this embodiment is in use, during the unfolding process: when the user pulls the second seat body 5 away from the first seat body 4, the second seat body 5 pulls the sunshade net 32 to open, and at the same time drives the folding arm 2 to unfold. The swing arms 21 in the folding arm 2 rotate relative to each other through the rotating connector 22 to achieve the unfolding action. When the folding arm 2 is completely unfolded, the positioning structure in the rotating connector 22 takes effect and locks the folding arm 2 in the unfolded state, so that the second seat body 5 and the first seat body 4 remain relatively stable, and the sunshade net 32 remains open, thereby providing a larger drying space. During the recycling process: when recycling is required, the user overcomes the locking force of the positioning structure to unlock it. The folding arm 2 loses the positioning constraint. Under the action of the self-retraction ability of the coil spring in the reel 31, the reel 31 automatically rolls up the sunshade net 32, and at the same time drives the second seat body 5 to approach the first seat body 4, and the folding arm 2 also folds accordingly to complete the recycling action.

[0081] Since a positioning structure is provided in the folding arm 2 and it can be automatically locked when the folding arm 2 is unfolded, it is possible to avoid the problem that the folding arm 2 bends under the action of an external force, resulting in the automatic contraction of the sunshade net 32 and affecting the drying experience.

[0082] In another embodiment, the drying assembly 3 is a foldable drying basket assembly, which includes a first connection end and a second connection end. The first connection end is connected to the first seat body 4, and the second connection end is connected to the second seat body 5. Through the folding and unfolding of the folding arm 2, the recycling and unfolding of the foldable drying basket assembly are realized.

[0083] Similarly, in this embodiment, the first connection end and the second connection end of the foldable drying basket assembly are respectively connected to the first seat body 4 and the second seat body 5. When in use, when the user pulls the second seat body 5 away from the first seat body 4, the second seat body 5 pulls the foldable drying basket assembly to unfold; when the user pushes the second seat body 5 and the first seat body 4 closer, the foldable drying basket assembly can be automatically pushed to fold.

[0084] In another embodiment, the drying assembly 3 is a drying rod assembly, which includes a plurality of small drying rods. When the folding arm 2 is in the unfolded state, the small drying rods can be dispersed and unfolded along the folding arm 2.

[0085] Specifically, in this embodiment, the small drying rod can be slidably connected or detachably connected to the folding arm 2. When the folding arm 2 is unfolded, the small drying rods can be spread out along the folding arm 2, and the unfolded small drying rods are supported by the folding arm 2; or after the folding arm 2 is unfolded, the small drying rods can be installed on the folding arm 2 one by one. When recycling, first slide the small drying rod out of the folding arm 2 or remove the small drying rod, and then fold the folding arm 2.

[0086] In one embodiment, the rotary connector 22 includes a first rotating part 221, a second rotating part 222 and a rotating shaft 223. The first rotating part 221 and the second rotating part 222 are rotatably connected through the rotating shaft 223; the first rotating part 221 and the second rotating part 222 are respectively used to connect two adjacent swing arms 21; the positioning structure includes an elastic positioning member 2211 and a positioning cooperation part. The elastic positioning member 2211 is arranged on the first rotating part 221, and the positioning cooperation part is arranged on the second rotating part 222. In the unfolded state of the folding arm 2, the elastic positioning member 2211 cooperates with the positioning cooperation part to increase the resistance to relative rotation between the first rotating part 221 and the second rotating part 222, so as to position the folding arm 2 in the unfolded state.

[0087] In the solution of this embodiment, when the folding arm 2 is unfolded or folded, the first rotating part 221 and the second rotating part 222 rotate relative to each other around the rotating shaft 223, driving two adjacent swing arms 21 to perform corresponding movements, so as to realize the morphological change of the folding arm 2. When the folding arm 2 is being unfolded (not fully unfolded), the elastic positioning member 2211 will undergo elastic deformation when subjected to an external force. When the folding arm 2 is unfolded to a proper position, the elastic positioning member 2211 will be in close contact with the positioning cooperation part, thereby increasing the resistance to relative rotation between the first rotating part 221 and the second rotating part 222. This increase in resistance enables the folding arm 2 to stably remain in the unfolded state without sufficient external force to overcome it, realizing the positioning function.

[0088] Through the cooperation of the elastic positioning member 2211 and the positioning cooperation part, the folding arm 2 can be effectively positioned in the unfolded state, avoiding the automatic folding of the folding arm 2 due to external factors (such as gentle breeze, slight collision, etc.) during use, ensuring the stability of the drying device in the unfolded state, and providing a reliable drying space for users. This is particularly important for the drying assembly 3 with the self-retracting ability, which can avoid the problem that the drying net 32 of the drying assembly 3 is easily automatically rolled up.

[0089] Moreover, the composition of this positioning structure is relatively simple. It only needs to respectively set the elastic positioning member 2211 and the positioning cooperation part on the first rotating part 221 and the second rotating part 222 of the rotary connector 22. This simple structure not only reduces the production cost, but also is convenient for processing and installation, improving the production efficiency.

[0090] Preferably, referring to Figures 10 - 11 , the first rotating part 221 includes a first connecting part and a first connecting head, and the first connecting head is provided with a shaft hole; the second rotating part 222 includes a second connecting part and two second connecting heads arranged at intervals, the second connecting head is provided with a shaft hole, the first connecting head is inserted between the two second connecting heads and the shaft holes are aligned up and down, and the rotating shaft 223 passes through the shaft holes of the first connecting head and the second connecting head, thus realizing the hinge connection. The first connecting part and the second connecting part are respectively connected to the two swing arms 21. This hinge structure is simple and has good stability.

[0091] In one embodiment, the first rotating part 221 is provided with an installation groove, and the elastic positioning member 2211 is installed in the installation groove; the positioning and matching part is a positioning groove 2221 arranged on the second rotating part 222. When the folding arm 2 is in the unfolded state, the elastic positioning member 2211 is aligned with the positioning groove 2221.

[0092] An installation groove is specially provided on the first rotating part 221. This installation groove provides a fixed installation position for the elastic positioning member 2211, enabling the elastic positioning member 2211 to be stably installed on the first rotating part 221, ensuring its accurate position and preventing it from moving randomly. When the elastic positioning member 2211 is aligned with the positioning groove 2221, the elastic positioning member 2211 partially or fully embeds into the positioning groove 2221 under the action of its own elastic force. Due to the positioning groove 2221 imposing certain constraints on the elastic positioning member 2211, the resistance to relative rotation between the first rotating part 221 and the second rotating part 222 is increased, enabling the folding arm 2 to stably maintain the unfolded state without sufficient external force, thus realizing the positioning of the unfolded state of the folding arm 2. When folding is required, the user only needs to apply a sufficiently large thrust to make the elastic positioning member 2211 overcome the elastic force and disengage from the positioning groove 2221.

[0093] In this embodiment, through the precise design of the installation groove and the positioning groove 2221, it can be ensured that the elastic positioning member 2211 is accurately aligned with the positioning groove 2221 when the folding arm 2 is unfolded, thus realizing the precise positioning function. This precise positioning can prevent the folding arm 2 from shaking or shifting in the unfolded state, ensuring the stability and reliability of the drying device.

[0094] Installing the elastic positioning member 2211 in the installation groove of the first rotating part 221 and designing the positioning and matching part as the positioning groove 2221 on the second rotating part 222, this structural form makes full use of the space inside the rotating connector 22, making the whole structure more compact. The compact structure not only saves space but also is conducive to improving the overall strength and stability of the rotating connector 22.

[0095] In one embodiment, the elastic positioning member 2211 includes an installation cylinder, a spring, and a ball. The spring is installed inside the installation cylinder. The ball is connected to the spring, and the spring can push the ball outwards. During installation, the installation cylinder is inserted into the installation groove of the first rotating portion 221. The spring can push the ball outwards. When the ball aligns with the positioning groove 2221, the ball snaps into the positioning groove 2221 for positioning. When folding is required, by applying a sufficiently large external force, the ball can overcome the elastic force to compress the spring and cause the ball to disengage from the positioning groove 2221, achieving disengagement from the positioning.

[0096] The structure in which the ball snaps into the positioning groove 2221 can provide a relatively stable positioning effect. The positioning groove 2221 has a strong restraining effect on the ball, which can effectively prevent the folding arm 2 from automatically folding under a slight external force in the unfolded state, ensuring the stability and safety of the drying device during use.

[0097] In other embodiments, the elastic positioning member 2211 can also be a columnar structure with elastic deformation, such as a rubber column, a silica gel column, etc.

[0098] In one embodiment, referring to Figure 11 and Figure 13 , a chute 2222 spaced from the positioning groove 2221 is further provided on the second rotating portion 222. The chute 2222 is used to provide a passage for the elastic positioning member 2211 during rotation.

[0099] During the unfolding or folding of the folding arm 2, the first rotating portion 221 and the second rotating portion 222 rotate relative to each other. When the elastic positioning member 2211 (the ball) does not reach the position of the positioning groove 2221, most of the rotation path of the elastic positioning member 2211 is in the chute 2222. The chute 2222 provides a relatively smooth moving space for the elastic positioning member 2211, so that the elastic positioning member 2211 will not be overly hindered (i.e., frictional force), thereby ensuring that the first rotating portion 221 and the second rotating portion 222 can rotate relative to each other more smoothly and reducing wear. When the elastic positioning member 2211 rotates to the edge of the chute 2222, the elastic positioning portion is squeezed and deformed (because there is a barrier between the chute 2222 and the positioning groove 2221, and this barrier will squeeze the elastic positioning member 2211). Then when the elastic positioning member 2211 aligns with the positioning groove 2221, the elastic force of the elastic positioning member 2211 is restored and it pops out and snaps into the positioning groove 2221 to achieve positioning.

[0100] During specific implementation, since the moving path of the elastic positioning member 2211 is arc-shaped, the chute 2222 is correspondingly set as arc-shaped and covers a part of the moving path of the elastic positioning member 2211. And the coverage range of the chute 2222 for the moving path of the elastic positioning member 2211 is as large as possible, as long as there is a barrier between the chute 2222 and the positioning groove 2221.

[0101] In this embodiment, the existence of the sliding groove 2222 provides an avoidance channel for the movement of the elastic positioning member 2211 in the non-positioning state, avoiding unnecessary friction or jamming between the elastic positioning member 2211 and the surface of the second rotating part 222 during the rotation process, making the relative rotation of the first rotating part 221 and the second rotating part 222 smoother, and improving the flexibility of the folding arm 2 to expand and fold. Since the elastic positioning member 2211 mainly moves in the sliding groove 2222 during the rotation process, the friction between the ball and other parts of the second rotating part 222 is reduced, the wear degree of the ball and the second rotating part 222 is reduced, the service life of the elastic positioning member 2211 and the second rotating part 222 is prolonged, and the maintenance cost of the product is reduced.

[0102] During the application process, the inventor found that after the folding arm 2 is unfolded, it is a cantilever structure extending towards one side relative to the first seat body 4. Since the folding arm 2 itself is a foldable structure, there is a fitting clearance error in the middle, and after unfolding, the free end of the folding arm 2 (i.e., the end connected to the second seat body 5) is likely to droop relative to the first seat body 4; another factor, the material strength of the folding arm 2 itself, also determines the degree of deformation after its unfolding, which will also cause the free end to droop after unfolding; in addition, when drying clothes on the drying net 32, the load on the folding arm 2 will increase, further aggravating its drooping effect. The drooping of the unfolded folding arm 2 will affect the user's impression of its stability, and to a certain extent, there is also a problem that the dried clothes slide and gather towards the lower side.

[0103] In one embodiment, the folding arm 2 is hinged to the first seat body 4 through a hinge, and the axial direction of the hinge is inclined relative to the vertical direction, so that in the unfolded state of the folding arm 2, it extends obliquely upward from the end connected to the first seat body 4 to the end connected to the second seat body 5.

[0104] Specifically, the folding arm 2 and the first seat body 4 are hinged through a hinge. This connection method allows the folding arm 2 to rotate relative to the first seat body 4, thereby realizing the expansion and folding functions of the folding arm 2. The key lies in that the axial direction of the hinge is inclined relative to the vertical direction. This inclined setting changes the spatial posture of the folding arm 2 after unfolding, so that in the unfolded state, it extends obliquely upward from the end connected to the first seat body 4 to the end connected to the second seat body 5.

[0105] After the hinge axis is inclined, when the folding arm 2 unfolds, it extends obliquely upward. This inclination angle preset an upward trend, which can exactly compensate for the sag of the end (free end) where the second seat body 5 is located due to factors such as fitting clearance error, material strength, and load-bearing. Through the compensation of the sag, the folding arm 2 can finally make the drying net 32 tend to be in a horizontal state under the influence of various factors. Since both ends of the drying net 32 are respectively connected to the first seat body 4 and the second seat body 5, when the inclination setting of the folding arm 2 can balance the sag effect, the drying net 32 can maintain a relatively horizontal position.

[0106] In this embodiment, the unfolded folding arm 2 makes the drying net 32 tend to be horizontal, which creates a more stable and reliable feeling for the user visually and in terms of the usage experience, improving the user's satisfaction and trust in the product. In addition, the horizontal drying net 32 can prevent the clothes spread on it from sliding and gathering towards the lower side due to the sag of the folding arm 2, ensuring that the clothes can be evenly spread on the drying net 32, improving the drying effect and space utilization rate. Importantly, by simply inclining the hinge axis, the problems of sagging and various issues caused by the folding arm 2 after unfolding are solved, without the need for complex modification of the structure of the folding arm 2 itself, reducing the production cost and design difficulty.

[0107] In one embodiment, the angle of inclination of the axis direction of the hinge relative to the vertical direction is 5 to 10°.

[0108] Specifically, there are fitting clearance errors in the folding arm 2 itself, and the gap sizes between different production batches or different components will fluctuate to a certain extent. The strength of the material of the folding arm 2 is different, and the deformation degree after unfolding also varies. The inclination angle range of 5 to 10° can flexibly adapt to these clearance errors to a certain extent. This angle range is obtained through multiple experiments and simulations. If the angle is too small, it may not be able to fully compensate for the sag caused by the gap; if the angle is too large, the folding arm 2 may be overly inclined, affecting the overall structural balance and aesthetics.

[0109] In this embodiment, the designed angle range of 5 to 10° enables the folding arm 2 to have a reasonable inclination angle in the unfolded state, enhancing the structural stability of the entire drying device, reducing the structural shaking and instability caused by the sag of the folding arm 2, and improving the safety and comfort of user use.

[0110] In one embodiment, as Figures 1 - 5 , and Figure 8 shown, it further includes a storage box 1. The storage box 1 includes a box seat 11. The first seat body 4 is installed on the box seat 11. When the folding arm 2 is in the folded state, the drying assembly 3, the folding arm 2, and the second seat body 5 are stored in the box seat 11.

[0111] Among them, by installing the first seat body 4 on the box seat 11, a stable connection relationship between the entire drying device and the storage box 1 is established. This installation method can be in various forms such as rivet connection, bolt connection, snap connection, etc., ensuring that the first seat body 4 is firmly fixed on the box seat 11, thereby providing a basis for subsequent storage operations. The folding arm 2 itself has the characteristic of being foldable. When storage is required, the user folds the folding arm 2, reducing its volume. Since the first seat body 4 has been installed on the box seat 11, the folded folding arm 2 and the drying assembly 3 and the second seat body 5 connected thereto can be smoothly placed into the internal space of the box seat 11 to complete the storage process.

[0112] The presence of the storage box 1 enables the drying device to maintain a neat and beautiful appearance when not in use. After storing each component, there will be no situation where the components of the drying device are randomly placed, improving the overall environmental aesthetics. In addition, storing each component in the box seat 11 can provide a certain degree of protection for them, reducing the direct erosion of the components by the external environment, such as dust, moisture, sunlight, etc., reducing the risk of component aging and damage, and extending the service life of the product.

[0113] In one embodiment, the storage box 1 includes a box cover 12, the second seat body 5 is installed on the box cover 12, and when the folding arm 2 is in a folded state, the box cover 12 covers the box seat 11. When in use, the user only needs to push and pull the box cover 12 to drive the second seat body 5 to move, and then drive the unfolding and folding of the folding arm 2 and the drying assembly 3.

[0114] In addition to the box seat 11, the storage box 1 is also provided with a box cover 12. The second seat body 5 is installed on the box cover 12, forming a structure in which the box cover 12 and the second seat body 5 are linked. When the folding arm 2 is in a folded state, the box cover 12 can cover the box seat 11, storing the drying assembly 3, the folding arm 2, and the second seat body 5 in the box seat 11. When in use, by simply pushing and pulling the box cover 12, the second seat body 5 can be driven to move, and then the folding arm 2 and the drying assembly 3 can be unfolded or folded.

[0115] Specifically, since the second seat body 5 is installed on the box cover 12, when the user applies a pushing or pulling force to the box cover 12, the box cover 12 will move in the pushing or pulling direction. The movement of the box cover 12 will drive the second seat body 5 to move synchronously. The second seat body 5 is connected to the folding arm 2, and the folding arm 2 is associated with the drying assembly 3. Therefore, the movement of the second seat body 5 will further drive the folding arm 2 to perform unfolding or folding actions, ultimately realizing the unfolding and folding of the drying assembly 3. After the folding arm 2 is folded, the box cover 12 can accurately cover the box seat 11. After being covered, the storage box 1 forms a relatively closed space, protecting the internal components.

[0116] Based on this embodiment, the user can complete the deployment and retraction of the folding arm 2 and the drying component 3 simply by pushing and pulling the box cover 12, without complex operation steps, greatly improving the convenience of use, especially suitable for users of different ages and operation capabilities. In addition, when the box cover 12 is closed on the box base 11, the storage box 1 provides a relatively enclosed and stable environment for the internal drying component 3, folding arm 2 and the second seat body 5, effectively preventing these components from being affected by external factors such as dust, moisture, and collision, and extending the service life of the product. In the storage state of the storage box 1, the box cover 12 is closed on the box base 11, and the overall appearance is simple and beautiful, without the situation of messy exposed components, improving the aesthetics of the product and the coordination of the home environment.

[0117] The inventor found that, on the one hand, since the folding arm 2 is a foldable structure, there will be an activity gap in itself, so it is difficult to ensure that after retraction, the box cover 12 can be accurately closed with the box base 11, and the misalignment of the closure will affect the airtightness and it doesn't matter. On the other hand, as can be seen from the previous text, the hinge connecting the folding arm 2 to the first seat body 4 is inclined, so the second seat body 5 and the box cover 12 will actually be inclined relative to the box base 11, and the inclination of the box cover 12 after retraction will affect the aesthetics and the airtightness of the closure.

[0118] In view of the above problems, in one embodiment, a first guiding portion 121 is provided on one side of the box cover 12 facing the box base 11, and a second guiding portion 421 is correspondingly provided on the box base 11. Through the cooperation and guidance of the first guiding portion 121 and the second guiding portion 421, the box cover 12 can be accurately aligned and closed on the box base 11.

[0119] A first guiding portion 121 is provided on the side of the box cover 12 facing the box base 11, and a second guiding portion 421 is provided at the corresponding position on the box base 11. These two guiding portions cooperate with each other to form a structure for guiding the box cover 12 to be accurately closed. Specifically, when the user pushes and pulls the box cover 12 to move it towards the box base 11 for closing, the first guiding portion 121 and the second guiding portion 421 start to contact and interact with each other. The first guiding portion 121 moves along the path set by the second guiding portion 421. Since the shape and position of the second guiding portion 421 are fixed, it can guide the first guiding portion 121 to move in the correct direction and position, thereby ensuring that the box cover 12 can be accurately aligned with the box base 11.

[0120] It can be understood that during the cooperation process of the first guiding portion 121 and the second guiding portion 421, the folding arm 2 will utilize its own activity gap and deformation to cooperate, and finally make the first guiding portion 121 and the second guiding portion 421 accurately cooperate in place, so that the box cover 12 and the box base 11 are accurately aligned.

[0121] In this embodiment, the cooperative guiding of the first guiding portion 121 and the second guiding portion 421 can enable the lid 12 to be accurately closed on the base 11, effectively reducing the situation of misalignment during closing. The accurate closing can ensure that the gap between the lid 12 and the base 11 is minimized, thereby improving the tightness of the storage box 1 and preventing external substances such as dust and moisture from entering the interior of the storage box 1, protecting components such as the folding arm 2 and the drying component 3 stored therein. At the same time, it also solves the problem that the lid 12 tilts after being closed due to the inclination of the hinge, enabling the lid 12 to maintain a flat and beautiful appearance in the closed state, avoiding the visual disharmony caused by the inclination, enhancing the aesthetics of the entire storage box 1, and making it better integrate into the home environment.

[0122] In one embodiment, referring to Figures 15 - 17 , two first guiding portions 121 each in a "C" shape and arranged facing each other are provided on the lid 12, and a guiding slot 1211 is formed inside the first guiding portion 121; the second guiding portion 421 is inserted into the guiding slot 1211 to achieve the alignment of the lid 12 and the base 11 during closing.

[0123] Two first guiding portions 121 each in a "C" shape and arranged facing each other are provided on the lid 12. This shape makes the guiding slot 1211 naturally formed inside the first guiding portion 121. The two "C" shaped structures are arranged opposite to each other, providing a clear guiding space for the insertion of the second guiding portion 421, and ultimately being able to form positioning between the base 11 and the lid 12 from multiple directions of up, down, left, and right, ensuring the stability after closing.

[0124] Among them, a guiding protrusion 1212 is provided on the inner side wall of the first guiding portion 121 at the guiding slot 1211, and an inclined guiding surface is provided on the side of the guiding protrusion 1212 facing the second guiding portion 421, enabling the second guiding portion 421 to be smoothly inserted into the guiding slot 1211 and ultimately guiding the lid 12 to be corrected in place.

[0125] Specifically, when the lid 12 moves towards the base 11 for closing, the second guiding portion 421 starts to contact the guiding slot 1211 of the first guiding portion 121. Due to the existence of the inclined guiding surface on the guiding protrusion 1212, even if there is a certain degree of initial position deviation between the second guiding portion 421 and the guiding slot 1211, the inclined guiding surface can also guide the second guiding portion 421, making it easier to enter the guiding slot 1211. The inclined guiding surface decomposes the lateral force received by the second guiding portion 421 into a component force along the guiding surface direction, pushing the second guiding portion 421 to gradually adjust to the correct insertion direction. When the second guiding portion 421 moves to a certain extent, it will be finally corrected to the correct position under the combined action of the guiding protrusion 1212 and the guiding slot 1211, achieving the accurate alignment and closing of the lid 12 and the base 11.

[0126] In one embodiment, in combination with Figure 4 , Figure 5 , Figure 8 and Figure 18 , a support cross beam 6 is further installed in the box base 11, and both ends of the support cross beam 6 are respectively used for connecting the drying rod 7 of the drying rack; when the box cover 12 is in the closed state, the box cover 12 covers the support cross beam 6.

[0127] A support cross beam 6 is installed inside the box base 11. The support cross beam 6 does not exist in isolation. Its two ends are respectively responsible for connecting the drying rods 7 of the drying rack, indicating that the support cross beam 6 is an important component for the interconnection between the structure of the drying rack and the storage box 1. When the box cover 12 is in the closed state, the box cover 12 covers the support cross beam 6 inside, forming a structure for storage and protection.

[0128] In the solution of this embodiment, the support cross beam 6 is installed in the box base 11 and connected to the drying rod 7 of the drying rack, realizing the organic combination of the structure of the drying rack and the structure of the storage box 1. This integrated design reduces the scattered arrangement of parts, makes the entire drying rack system more compact and reasonable, saves space, and at the same time facilitates the installation and use of the product. The support cross beam 6 installed in the box base 11 also increases the stability of the internal structure of the box base 11. During the use of the drying rack, the support cross beam 6 can provide reliable support for the drying rod 7, reduce the shaking and deformation of the drying rod 7, and ensure the stability and safety of the drying rack; at the same time, the fixed connection between the support cross beam 6 and the box base 11 also helps to maintain the overall structural stability of the storage box 1, thereby improving the stability of the drying net 32 and the folding arm 2 after deployment.

[0129] When the box cover 12 covers the support cross beam 6 in the closed state, it can effectively prevent the support cross beam 6 and the drying rod 7 that may be stored inside from being damaged by the external environment, such as dust, moisture, collision, etc. This helps to extend the service life of the support cross beam 6 and the drying rod 7, reduce the risk of damage caused by environmental factors, and reduce the maintenance and replacement costs. Moreover, in the storage state, the box cover 12 covers the support cross beam 6 and other components inside, making the appearance of the entire storage box 1 more tidy and beautiful, avoiding the messy feeling caused by the exposure of components, being able to better integrate into the home environment, and improving the overall quality of the product and the user experience.

[0130] In one embodiment, referring to Figure 5 , the support cross beam 6 is located in the bottom area of the first seat body 4, and the support cross beam 6 and the first seat body 4 overlap at least partially in the vertical direction.

[0131] The supporting beam 6 partially overlaps with the first base body 4 in the vertical direction. This structural arrangement enables a more rational use of the internal space of the entire clothes drying rack and the storage box 1, reduces space waste caused by the dispersed arrangement of components, and enables the product to integrate more functional components in a limited space while maintaining the compactness of the structure.

[0132] In one embodiment, referring to Figure 5 The first seat body 4 is provided with a first mounting groove 411 and a second mounting groove 412 at upper and lower intervals, both of which are facing the second seat body 5, the folding arm 2 is installed in the first mounting groove 411, and the reel 31 is installed in the second mounting groove 412; the supporting beam 6 is located on the side of the second mounting groove 412 facing the second seat body 5, and the supporting beam 6 partially overlaps with the second mounting groove 412 in the vertical direction.

[0133] The first mounting groove 411 and the second mounting groove 412 are arranged in the first base 4 at intervals, and the folding arm 2 and the reel 31 are installed respectively, so that the components are reasonably arranged on the first base 4, and the space of the first base 4 is fully utilized, and mutual interference between the components is avoided, so that the structure of the entire clothes drying rack and the storage box 1 is more compact and space is saved. In addition, the first mounting groove 411 and the second mounting groove 412 can provide storage space for the folding arm 2 and the drying assembly 3 respectively, so that the two can have clear storage belonging in the storage box 1, and ensure the stability of the storage and unfolding process.

[0134] In the vertical direction, the support beam 6 partially overlaps with the second mounting groove 412, so that the support beam 6 can be fully utilized to set the support beam 6 on the side of the notch of the second mounting groove 412, so as to shorten the entire drying device and make its structure more compact. It should be noted that the support beam 6 blocks the second mounting groove 412, and sufficient space should be reserved to allow the drying net 32 ​​to extend out. Preferably, the height of the top surface of the support beam 6 should not exceed the height of the axis of the reel 31, so that the drying net 32 ​​will not have any contact friction with the support beam 6 during the extension and retraction process, thereby avoiding the problem of wear of the drying net 32.

[0135] In one embodiment, referring to Figure 14 The first seat body 4 includes a seat body main body 41 and two end fixing seats 42 respectively connected to the two ends of the seat body main body 41, the first mounting groove 411 and the second mounting groove 412 are arranged on the seat body main body 41, and the two ends of the reel 31 are respectively installed on the two end fixing seats 42.

[0136] The first base body 4 is composed of a base body main body 41 and two end fixing bases 42. The two end fixing bases 42 are respectively connected to both ends of the base body main body 41. This split structure provides a basic framework for the installation and function realization of each component. Both ends of the reel 31 are respectively installed on the two end fixing bases 42. The end fixing bases 42 play a role in supporting and fixing the reel 31, ensuring that the reel 31 can rotate stably.

[0137] The split structure of the first base body 4 makes the installation of the folding arm 2 and the reel 31 more convenient. During the installation process, the folding arm 2 can be first installed in the first installation groove 411 of the base body main body 41, and the base body main body 41 with the folding arm 2 can be installed into the box base 11. Then, both ends of the reel 31 are respectively installed on the end fixing bases 42, and the two end fixing bases 42 with the reel 31 are installed into the box base 11, thereby reducing the installation difficulty.

[0138] In addition, the base body main body 41 and the end fixing bases 42 respectively undertake different functions and jointly provide support for the folding arm 2 and the reel 31. The base body main body 41 fixes the folding arm 2 through the installation groove, and the end fixing bases 42 firmly fix both ends of the reel 31. This structural design can effectively disperse the stress generated by each component during the working process, reduce the structural deformation or damage caused by uneven stress, and improve the stability and reliability of the entire drying rack structure.

[0139] In one embodiment, the second guiding portion 421 is disposed on the end fixing base 42.

[0140] The second guiding portion 421 is disposed on the end fixing base 42, which means that the end fixing base 42 not only undertakes functions such as fixing the reel 31, but also serves as a bearing component of the second guiding portion 421, and together with the first guiding portion 121 disposed on the box cover 12 described above, constitutes a positioning structure for the covering of the box cover 12 and the box base 11.

[0141] Using the existing end fixing base 42 to set the second guiding portion 421 does not require additional dedicated components for positioning, simplifies the overall structure of the product. This not only reduces the manufacturing cost of the product, but also reduces the weight and volume of the product, making the product lighter, easier to install and use.

[0142] On the other hand, this embodiment also provides a drying rack, including:

[0143] Two parallel drying rods 7;

[0144] At least one drying device as described above, and the drying device is connected to the ends of the two drying rods 7.

[0145] Among them, two drying rods 7 are arranged in parallel, which is the basic structural framework of the clothes hanger and provides the main hanging space for drying clothes. During implementation, the drying rod 7 can be a fixed drying rod 7 or a telescopic drying rod 7.

[0146] At least one drying device is connected to the ends of the two drying rods 7. By combining the drying device with the drying rod 7, the clothes hanger not only has the drying function of the traditional drying rod 7 but also adds the additional functions brought by the drying device, expands the drying space, and enriches the usage modes of the clothes hanger. Preferably, two drying devices are symmetrically arranged on two opposite sides of the clothes hanger to provide an extended drying space from both sides and make the whole clothes hanger more balanced and stable.

[0147] The connection between the drying device and the end of the drying rod 7 needs to ensure the structural stability and reliability, and usually, forms such as bolt connection and riveting may be adopted. For example, bolts are used to pass through the support cross beam 6 and then locked to the end of the drying rod 7.

[0148] On the other hand, a clothes dryer is provided, which includes the above-mentioned clothes hanger.

[0149] The clothes dryer includes a main body, a telescopic bracket, and a clothes hanger. The upper and lower ends of the telescopic bracket are respectively connected to the main body and the clothes hanger. A lifting drive device is arranged in the main body, which is connected to the clothes hanger and can drive the clothes hanger to lift.

[0150] Similarly, based on the clothes hanger of this embodiment, the clothes dryer of this embodiment can provide more drying space on the basis of the traditional clothes dryer and meet more drying needs.
