Description

Technical Field

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

[0002] A clothes drying machine is a new type of household appliance for drying clothes. With the improvement of people's living standards, it is becoming more and more popular due to its convenience and high degree of automation. Clothes drying machines are generally equipped with a clothes drying rod and a quilt drying rod to dry clothes or quilts of different sizes.

[0003] For example, the Chinese patent application number "202311458402.1" discloses a locking connection device for drying rods, which is provided with a pull rope assembly that connects the main and auxiliary drying rods. When the auxiliary drying rod is pulled down for use, the connection of the tension spring provides a certain buffer for the downward movement of the auxiliary drying rod, reducing the vibration or shaking generated when the auxiliary drying rod moves downward, and can achieve automatic recovery of the auxiliary drying rod through the elastic restoring force of the tension spring. However, the maximum lowering distance of the quilt drying rod and the clothes drying rod of this structure is fixed, which is specifically related to the length of the tension spring. When the distance needs to be increased, a longer tension spring and sleeve need to be replaced, which is cumbersome to install and has a high failure rate. Utility Model Content

[0004] The main purpose of this application is to provide a quilt drying rod structure that can realize automatic retraction of the quilt drying rod. The structure is simple, and there is no need to replace the telescopic component of the wire rope, and it is easy to install and assemble.

[0005] Another object of the present application is to provide a clothes drying machine including the above-mentioned clothes drying rod structure.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] As a first aspect, the present application relates to a clothes-drying rod structure, which includes a first clothes-drying rod, a second clothes-drying rod and a traction member connecting the two. The second clothes-drying rod is provided with a rotating shaft that can rotate relative to the second clothes-drying rod. One end of the traction member is fixed to the first clothes-drying rod, and the other end thereof is connected to the rotating shaft in the second clothes-drying rod. The traction member is wound around the rotating shaft and is retracted and released through the rotating shaft. The rotating shaft is connected to a reset elastic member, one end of the reset elastic member is connected to the rotating shaft, and the other end thereof is fixed relative to the second clothes-drying rod. The reset elastic member undergoes elastic deformation with the rotation of the rotating shaft. When the reset elastic member is in its original state, the traction member is retracted in the second clothes-drying rod.

[0008] It is further configured that the reset elastic member includes a coil spring, both ends of the coil spring are provided with connecting members, and the two ends of the coil spring are fixedly connected to the rotating shaft and the second drying rod respectively through the connecting members.

[0009] Further configuration: an installation box for placing the coil spring is also provided in the second drying rod, and a matching groove for matching with the connecting piece located on the outer periphery of the coil spring is provided on the outer side wall of the installation box.

[0010] Further configuration: a mounting seat is also provided in the second drying rod, a limiting column is provided on the mounting seat, the rotating shaft is sleeved on the limiting column and can rotate relative to the limiting column, and the end of the rotating shaft away from the connection with the limiting column is rotatably connected to the mounting box.

[0011] It is further provided that: the end of the rotating shaft close to the connection with the limiting post is provided with a connecting hole for the limiting post to be inserted and rotated together.

[0012] It is further configured that a through hole is provided on the rotating shaft for the end of the traction member to pass through, the through hole extends to the bottom of the connecting hole, and a limit block with an outer diameter greater than the transverse diameter of the through hole is provided on the end of the traction member.

[0013] It is further provided that the installation box is further provided with an installation cover for encapsulating the coil spring inside the installation box, and a through hole is provided in the center of the installation cover for connecting the connecting piece located in the center of the coil spring with the rotating shaft.

[0014] It is further provided that: the installation box is provided with at least two slots, the installation cover is provided with an inserting block that rotatably cooperates with the slots, and the inserting block is provided in a one-to-one correspondence with the slots.

[0015] Further configuration: the second drying rod is arranged below the first drying rod.

[0016] As a second aspect, the present application relates to a clothes drying machine, which includes a clothes drying machine body and the clothes drying rod structure as described above.

[0017] Compared with the existing technology, the solution of this application has the following advantages:

[0018] The drying rod structure involved in the present application realizes the automatic retraction and extension of the traction member by setting a rotating shaft and a reset elastic member. When there is no need to use the second drying rod alone, that is, when the second drying rod is not load-bearing or subjected to other external forces, it can automatically retract to the position where it is engaged with the first drying rod. It is easy to use and reduces the occupation of the drying space. The drying structure has a simple structure, few parts, easy assembly, and low cost. In addition, traction members of different lengths can be replaced according to different required drying intervals. There is no need to replace the retraction and extension structure of the entire set of traction members, which reduces the difficulty of after-sales service.

[0035] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0036] In view of the current problems of fixed drying distance and complex retractable structure of ceiling-mounted clothes drying machines, please combine Figures 1 to 7The present application discloses a drying rod structure, which includes a first drying rod 1, a second drying rod 2, and a pulling member 3 connecting the first and second drying rods. A rotating shaft 4 is provided within the second drying rod 2, which is rotatable relative to the second drying rod 2. One end of the pulling member 3 is fixed to the first drying rod 1, and the other end is connected to and wound around the rotating shaft 4, allowing the pulling member 3 to be retracted into the second drying rod 2. When the first and second drying rods 1 and 2 need to be separated, the pulling member 3 extends from the second drying rod 2 to change the distance between the first and second drying rods 1 and 2. At the same time, the rotating shaft 4 is connected to a restoring elastic member, one end of which is connected to the rotating shaft 4 and the other end of which is fixed relative to the second air-drying rod 2. When the traction member 3 extends out of the second air-drying rod 2 under the action of an external force, it drives the rotating shaft 4 to rotate relative to the second air-drying rod 2. The restoring elastic member undergoes elastic deformation as the rotating shaft 4 rotates. When the external force applied to the first air-drying rod 1 or the second air-drying rod 2 is released, the rotating shaft 4 is reversed under the restoring force of the restoring elastic member so that the traction member 3 is rewound around the rotating shaft 4, thereby realizing the recovery of the traction member 3. That is, when the restoring elastic member is in its original state, the second air-drying rod 2 is in contact with the first air-drying rod 1, and the traction member 3 can be retracted into the second air-drying rod 2. The present application provides a retractable structure for the traction member 3 by providing a rotating shaft 4 in combination with the restoring elastic member, which can reduce the difficulty of installation and assembly, and the air-drying rod can be automatically retracted during the drying process, which is convenient and quick.

[0037] The traction member 3 in this embodiment is a steel wire rope, which has the advantages of high strength and strong bearing capacity, and can extend the service life of the clothes drying machine.

[0038] In a specific embodiment, a second airing rod 2 is disposed below the first airing rod 1. The first airing rod 1 is configured as a clothesline with multiple hanging holes 11 along its length to facilitate drying clothes at intervals. The second airing rod 2 can be configured as a quilt-drying rod, suspended below the clothesline by a wire rope, allowing users to simultaneously dry clothes and quilts. In the initial state of the airing rod structure, the quilt-drying rod fits snugly with the clothesline, with the wire rope reeled in the second airing rod 2. To use the quilt-drying rod independently, the quilt-drying rod is pulled downward, causing the wire rope to be pulled out of the second airing rod 2. This tension overcomes the elastic force of the return spring on the rotating shaft 4, causing the return spring to elastically deform as the rotating shaft 4 rotates as the wire rope extends from the second airing rod 2. During the quilt-drying process, the tension on the wire rope can be provided by the weight of the quilt. When the quilt drying rod is no longer needed for use alone, the external force applied to the quilt drying rod is released, and the restoring force of the reset elastic member will cause the rotating shaft 4 to reverse to retract the wire rope, and the quilt drying rod will return to its original state of being in contact with the clothes drying rod, avoiding the quilt drying rod taking up space, which is simple and convenient.

[0039] In this embodiment, the resilient return member comprises a coil spring 5, each end of which is provided with a connector 51. These connectors 51 secure the coil spring 5 to the rotating shaft 4 and the second airing rod 2, respectively. The connector 51 at the center of the coil spring 5 is connected to the rotating shaft 4, while the connector 51 at the other end, located on the outer periphery of the coil spring 5, is secured to the second airing rod 2. Furthermore, a mounting box 7 for the coil spring 5 is provided within the second airing rod 2. The mounting box 7 is screwed to the bottom wall of the second airing rod 2. In this embodiment, the mounting box 7 is a round box with mating grooves 71 on its outer wall for mating with the connectors 5 located on the outer periphery of the coil spring 5. Specifically, the connecting piece 51 of this embodiment is provided with a hook claw, which can be formed by bending the end of the coil spring 5. The hook claw located at the central end of the coil spring 5 is inserted into the matching hole 41 provided on the rotating shaft 4, and the hook claw located at the outer end of the coil spring 5 is clamped into the matching groove 71 of the installation box 7, that is, the hook claw 51 of the coil spring 5 located at the outer periphery of the coil spring 5 is fixed relative to the second drying rod 2, so that when the hook claw 51 located at the center of the coil spring 5 rotates with the rotating shaft 4, the outer ring of the coil spring 5 is limited by the installation box 7 and cannot be contracted synchronously, and the coil spring 5 can be in a rotationally tightened state (see Figure 5 ), and when the wire rope is not pulled by external force, the coil spring 5 can be reset to reverse the rotation shaft 4, and the wire rope can be rewound onto the rotation shaft 4 to return to the initial state (see Figure 6 ).

[0040] At the same time, a mounting base 6 for connecting to the rotating shaft 4 is also provided in the second drying rod 2, and a limiting column 61 is provided on the mounting base 6. The end of the rotating shaft 4 connected to the mounting base 6 is provided with a connecting hole 42 for the limiting column 61 to be inserted and rotated. The rotating shaft 4 is sleeved on the limiting column 61 through its connecting hole 42 and can rotate relative to the limiting column 61, and the end of the rotating shaft 4 away from the limiting column 61 can extend to the installation box 7 and be plugged into the installation box 7. The rotating shaft 4 can rotate relative to the installation box 7, so that the rotating shaft 4 can be limited between the mounting base 6 and the installation box 7, thereby improving the stability of the rotating shaft 4.

[0041] The mounting base 6 in this embodiment includes a pressure plate 62 and a stud 63. The stud 63 abuts the pressure plate 62 against the top of the second air-drying rod 2 and is screwed to the bottom wall of the second air-drying rod 2. The limiting post 61 is fixed to the pressure plate 62 to facilitate installation. The rotating shaft 4 is provided with a through hole 43 for the end of the wire rope to pass through. The through hole 43 extends below the connecting hole 42 of the rotating shaft 4. At the same time, a limiting block 31 with an outer diameter greater than the transverse diameter of the through hole 43 is provided at the end of the wire rope. After the wire rope passes through the through hole 43, the limiting block 31 can prevent the wire rope from disengaging from the through hole 43. After the rotating shaft 4 is plugged into the limiting post 61, the limiting block 31 can also prevent the wire rope from axially disengaging from the through hole 43. Since the steel wire rope and the rotating shaft 4 are not fixedly connected, it is convenient to replace steel wire ropes of different lengths to achieve different adjustments to the spacing between the first drying rod 1 and the second drying rod 2 without replacing the entire storage component, which can reduce the difficulty of installation and assembly, and also reduce the difficulty of subsequent adjustment of the spacing between the first drying rod 1 and the second drying rod 2.

[0042] The maximum drying distance of the first drying rod 1 and the second drying rod 2 is related to the length of the steel wire rope. The steel wire rope is wound on the rotating shaft 4. The maximum drying distance can be calculated by the diameter of the rotating shaft 4 and the number of windings of the steel wire rope. When the diameter of the rotating shaft 4 is limited to D, the maximum drying distance L=(n-2)πD, where n is the total number of windings and 2 turns is the preset safety distance.

[0043] Furthermore, the mounting box 7 is provided with a mounting cover 8 for enclosing the coil spring 5 within the mounting box 7 to enhance the stability of the coil spring 5 during expansion and contraction. A through-hole 81 is provided in the center of the mounting cover 8 for connecting the hook 51 of the coil spring 5 located at the center thereof to the rotating shaft 4. The mounting cover 8 is detachably connected to the mounting box 7. The mounting box 7 is provided with at least two slots 72, and the mounting cover 8 is provided with inserts 82 that rotatably engage with the slots 72. The inserts 82 are arranged in a one-to-one correspondence with the slots 72, facilitating easy installation. The mounting cover 8 cooperates with the mounting box 7 to enclose the coil spring 5 within the mounting box 7.

[0044] The present application sets two steel wire ropes to connect the two ends of the first drying rod 1 and the second drying rod 2 respectively. A set of rotating shafts 4 and reset elastic parts are respectively provided at the two ends of the second drying rod 2, and the elastic deformation capabilities of the two sets of reset elastic parts are the same, thereby ensuring that the retraction and extension capabilities of the steel wire ropes at both ends of the drying rod are consistent, thereby ensuring the balanced use of the second drying rod 2.

[0045] A buckle 21 is provided at the top of the second airing rod 2, and a snap-fit ​​portion (not shown) is provided at the bottom of the first airing rod 1 to engage with the buckle 21. The engagement of the buckle 21 with the snap-fit ​​portion ensures a stable connection between the second airing rod 2 and the first airing rod 1 when not in use, and also allows the user to easily determine whether the quilt airing rod has been retracted. Multiple buckles 21 are provided along the length of the second airing rod 2, and multiple snap-fit ​​portions are provided at the bottom of the first airing rod 1, corresponding to the multiple buckles 21.

[0046] In summary, the drying rod structure of the present application realizes automatic retraction and extension of the steel wire rope by providing a rotating shaft 4 in conjunction with a reset elastic member. When the second drying rod 2 is not needed, the second drying rod 2 can automatically retract to a position of engagement with the first drying rod 1 when it is not bearing any weight or being subjected to any other external force. This is convenient to use and reduces the space occupied by the drying. The drying structure has a simple structure, few parts, is easy to assemble, and is low in cost. In addition, the steel wire rope of different lengths can be replaced according to different required drying intervals without having to replace the entire set of steel wire rope retraction and extension structures, which reduces the difficulty of after-sales service.

[0047] The present application also relates to a clothes drying machine, comprising a clothes drying machine body and a drying rod structure as described above. The clothes drying machine body is capable of controlling the height of the drying rod structure to adapt to the user's needs. The clothes drying machine using the drying rod structure of the present application can meet the dual needs of drying clothes and quilts. When only clothes or other small items need to be dried, a second drying rod 2, which serves as a quilt drying rod, is fixed below a first drying rod 1, which serves as a clothes drying rod, by means of a stopper 31 and a clamping portion. At this time, a steel wire rope is reeled into the second drying rod 2, allowing clothes to be dried without disassembling the second drying rod 2. The second drying rod 2 does not affect the drying of clothes, thus saving space and achieving a convenient and neat function. When quilts or other large items need to be dried, the user simply pulls down the second drying rod 2, causing the steel wire rope to extend outside the second drying rod 2. Under load or external force, the second drying rod 2 automatically stretches the steel wire rope to its maximum drying distance, facilitating the drying of quilts while not affecting the drying of clothes on the first drying rod 1 above. When the second clothes-drying rod 2 is no longer needed, the quilt or other heavy objects on the second clothes-drying rod 2 can be removed, and the steel wire rope can be rewound around the rotating shaft 4 under the elastic restoring force of the reset elastic member inside the second clothes-drying rod 2, so that the second clothes-drying rod 2 automatically returns to the engaging position of the first clothes-drying rod 1. The operation is convenient and no additional operation is required by the user, thereby improving the convenience of using the clothes-drying machine.

[0048] The above description is only part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
