Description

Technical Field

[0001] This application relates to the technical field of clothes dryers, and more particularly to a clothes dryer. Background Technology

[0002] In the current field of dryer casing assembly technology, the commonly used connection methods are mainly bolt connections or simple plug-in structures. While these traditional connection methods can meet basic assembly requirements to a certain extent, they have revealed a series of problems in actual operation. Because the dimensional accuracy requirements of dryer casing components are extremely strict, a significant amount of time is often spent repeatedly adjusting the positions of each component during assembly to ensure precise alignment of the connection points. This process not only greatly reduces assembly efficiency but also significantly increases labor costs, hindering the optimal control of production costs.

[0003] More importantly, traditional fixing methods, such as screw fixing, not only require additional specialized tools, increasing the complexity of the operation and the skill requirements of the operators, but also often have limited tolerance design. This leads to an increased risk of wear between components during actual assembly, and may also affect the overall stability and lifespan of the dryer due to insecure installation. Therefore, how to improve the assembly method of the dryer casing, increase assembly efficiency, reduce labor costs, and ensure the firmness of the connections and the durability of the components has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this application is to provide a clothes dryer that simplifies the assembly process of the outer casing, reduces debugging time, and improves installation stability.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, a clothes dryer is provided, comprising: a chassis, a front housing, a rear housing, and a positioning and guiding structure. The front housing and the rear housing are both mounted on the chassis, and the opposite sides of the front housing and the rear housing are positioned and spliced ​​by the positioning and guiding structure. The positioning and guiding structure includes a guide portion protruding from the front housing, a guide groove formed in the rear housing, and an elastic buckle provided on the rear housing. The guide groove is a trapezoidal cross-section groove that cooperates with the guide portion for positioning. The width of the guide groove is 0.5 mm to 1.5 mm larger than the width of the guide portion. The guide portion is also provided with a snap-fit ​​opening that cooperates with the elastic buckle for engaging.

[0007] Furthermore, the front housing is provided with a plurality of first card interfaces at intervals along the edge where it is spliced ​​with the rear housing, and the rear housing is provided with a first protrusion that engages with and is fixed in place by the plurality of first card interfaces.

[0008] Furthermore, an opening is formed on the side of the front housing opposite to the rear housing, and a door panel is movably installed at the opening.

[0009] Furthermore, the door panel includes a support body and a panel body, the panel body being hinged to the support body.

[0010] Furthermore, the support body has a plurality of second protrusions on one side relative to the front housing, and the front housing has a plurality of second snap-fit ​​interfaces that engage and fix with the second protrusions.

[0011] Furthermore, a sealing strip is provided at the joint between the door panel and the front housing.

[0012] Furthermore, the front housing and the rear housing are provided with arc-shaped positions on their opposite edges. After the front housing and the rear housing are spliced ​​together, the two arc-shaped positions form a mounting position, on which a side plate for maintenance and disassembly is detachably installed.

[0013] Furthermore, the rear housing includes a connecting portion and a splicing portion. The splicing portion is mounted on top of the chassis via the connecting portion, and the splicing portion is joined with the front housing.

[0014] Furthermore, the contact surfaces of the guide portion and the guide groove are coated with a wear-resistant coating.

[0015] Furthermore, the chassis is equipped with a drainage structure and a heat dissipation structure.

[0016] The beneficial effects of this application are as follows: First, the precise fit design between the guide groove and the guide part enables rapid positioning during assembly. This innovation significantly reduces manual adjustment time, increasing assembly efficiency by more than 30% compared to traditional methods and significantly accelerating the production pace. Second, the ingenious design of the tolerance gap effectively absorbs manufacturing tolerances and deviations during installation, reducing the risk of wear between components and enhancing overall fault tolerance, ensuring high assembly precision and component durability. Furthermore, in the initial fixing stage, the application of elastic clips achieves a stable connection without the need for additional tools, while subsequent bolt reinforcement provides double protection, greatly improving the stability and reliability of the shell connection. This series of design optimizations not only simplifies the installation process but also significantly reduces labor and time costs, making it particularly suitable for large-scale mass production and bringing considerable cost savings to enterprises.

[0024] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] like Figures 1-5 As shown, this embodiment provides a clothes dryer, including: a chassis 1, a front housing 2, a rear housing 3, and a positioning guide structure 4. The front housing 2 and the rear housing 3 are both mounted on the chassis 1, and the opposite sides of the front housing 2 and the rear housing 3 are positioned and spliced ​​by the positioning guide structure 4. The positioning guide structure 4 includes a guide portion 401 protruding from the front housing 2, a guide groove 402 formed in the rear housing 3, and an elastic buckle 403 provided on the rear housing 3. The guide groove 402 is a trapezoidal cross-section groove that cooperates with the guide portion 401 for positioning. The width of the guide groove 402 is 0.5mm to 1.5mm larger than the width of the guide portion 401. The guide portion 401 is also provided with a snap-fit ​​opening that cooperates with the elastic buckle 403.

[0028] Based on the above scheme, the front housing 2 and the rear housing 3 are securely mounted on the chassis 1, and their opposite sides are quickly and accurately joined by an innovative positioning and guiding structure 4. The core components of this positioning and guiding structure 4 include a guide portion 401 protruding from the front housing 2, a trapezoidal cross-section guide groove 402 opened in the rear housing 3, and an elastic buckle 403 provided on the rear housing 3.

[0029] During assembly, the precise fit between the guide part 401 and the guide groove 402 plays a crucial role. The trapezoidal cross-section design of the guide groove 402 allows the guide part 401 to slide smoothly and stably into it until it reaches the predetermined position. More ingeniously, the width of the guide groove 402 is intentionally designed to be 0.5mm to 1.5mm wider than the width of the guide part 401. This small tolerance not only ensures that the guide part 401 can easily enter the guide groove 402, but also provides some adjustment space during assembly, effectively absorbing manufacturing tolerances and installation deviations, enhancing overall fault tolerance, and greatly reducing the risk of wear between components.

[0030] Once the guide section 401 has fully slid into the guide groove 402, it will meet the elastic buckle 403 provided on the rear housing 3. At this time, the pre-set slot on the guide section 401 and the elastic buckle 403 achieve precise engagement. This process can be completed without the assistance of additional tools, relying solely on the structure of the component itself, which not only simplifies the operation process but also significantly improves the assembly efficiency.

[0031] Furthermore, to ensure the robustness of the shell connection, this solution incorporates dual safeguards. After an initial secure connection is achieved using the elastic clips 403, further tightening can be achieved using bolts. This design not only enhances the stability of the connection but also makes the entire assembly process more flexible and reliable.

[0032] This series of innovative designs not only simplifies the installation process and reduces the skill requirements for operators, but also significantly reduces labor and time costs, making this technical solution particularly suitable for large-scale mass production. At the same time, due to the significant improvement in assembly efficiency and precision, as well as enhanced stability, this technical solution brings revolutionary improvements to the assembly of dryer casings, possessing extremely high practical value and application prospects.

[0033] Furthermore, the front housing 2 is provided with multiple first locking interfaces 201 at intervals along the edge where it is joined to the rear housing 3. The rear housing 3 is provided with first protrusions 303 that engage with and are fixed to the multiple first locking interfaces 201. After the guide portion 401 and the guide groove 402 have completed initial guidance and positioning, the first protrusions 303 of the rear housing 3 can easily and accurately engage with the first locking interfaces 201 of the front housing 2. This process not only achieves rapid locking and fixing between the housing components but also provides a stable support point for subsequent further fixing. Due to the precise engagement between the first locking interfaces 201 and the first protrusions 303, the debugging time during assembly is greatly reduced, and the assembly efficiency is improved. This locking and fixing structure also significantly enhances the stability of the housing connection. After initial locking, even without additional fixing measures, the housing components can maintain a stable connection, avoiding performance degradation or safety hazards caused by component loosening. At the same time, this design also provides a solid foundation for subsequent bolt fixing and other further reinforcement measures, ensuring the reliability and safety of the entire assembly process.

[0034] In some embodiments, the front housing 2 has an opening on the side opposite to the rear housing 3, and a door panel 5 is movably mounted at the opening. The door panel 5 includes a support body 501 and a plate body 502, with the plate body 502 hinged to the support body 501. The front housing 2 has a carefully designed opening on the side opposite to the rear housing 3 to facilitate the insertion and removal of clothing. A door panel 5 is movably mounted at this opening, cleverly composed of the support body 501 and the plate body 502. The support body 501, as the main load-bearing and fixing structure of the door panel 5, is firmly installed at the edge of the opening in the front housing 2, ensuring the stability and durability of the door panel 5. The plate body 502 is the part that the user can directly contact during actual use; it is responsible for closing or opening the opening for clothing insertion and removal. To achieve flexible opening and closing of the plate body 502, a hinged connection is used to connect the plate body 502 to the support body 501. This design not only ensures that the door panel 5 opens and closes smoothly and steadily, but also greatly enhances the user experience. In summary, by providing an opening in the front housing 2 and movably mounting the door panel 5, composed of the support body 501 and the plate body 502, the dryer design of this application further improves user convenience and comfort while maintaining efficient assembly and stable connection.

[0035] Meanwhile, the support body 501 is provided with a plurality of second protrusions 503 on one side opposite to the front housing 2, and the front housing 2 is provided with a plurality of second snap-fit ​​interfaces 202 that cooperate with and snap-fit ​​the second protrusions 503. This design not only enhances the connection stability between the door panel 5 and the front housing 2, but also further simplifies the installation process and improves the ease of assembly.

[0036] Specifically, after the door panel 5 is installed at the opening via a hinge, the second protrusion 503 on the support 501 can easily and precisely engage with the second locking interface 202 on the front housing 2. This process not only achieves quick locking and fixation between the door panel 5 and the front housing 2, but also provides a solid guarantee for the stability and durability of the door panel 5. Due to the precise fit between the second protrusion 503 and the second locking interface 202, the debugging time during assembly is greatly reduced, improving assembly efficiency. This locking and fixing structure also ensures that the door panel 5 remains tightly fitted when closed, effectively preventing clothes from leaking out of the opening during drying, thus improving the overall performance and safety of the dryer. At the same time, because the design of the second protrusion 503 and the second locking interface 202 has a certain degree of elasticity and tolerance, even if slight dimensional deviations or deformations occur during use, it can maintain a stable connection through its own adjustment capabilities, avoiding performance degradation or safety hazards caused by loose components.

[0037] Furthermore, a sealing strip is provided at the joint between the door panel 5 and the front housing 2. As an elastic material, the sealing strip possesses excellent sealing and aging resistance. When the door panel 5 is closed, the sealing strip fits tightly against the joint between the door panel 5 and the front housing 2, effectively preventing heat and moisture generated during the drying process from leaking out through the gaps. This not only improves the drying efficiency of the dryer but also maintains a stable internal temperature, thereby extending the drying time of clothes and protecting the internal electronic components from the effects of a humid environment.

[0038] The sealing strip also reduces noise transmission. During the operation of the dryer, internal vibrations and noise often leak out through the gap between the door panel 5 and the front casing 2, affecting the user experience. The sealing strip effectively isolates this noise, making the dryer quieter and more stable during operation.

[0039] It's worth mentioning that the installation and maintenance of the sealing strip are also very convenient. It is typically fixed to the edge of the door panel 5 or the front housing 2 using simple clips or adhesive. When the user needs to replace or clean the sealing strip, it can be easily removed without any complicated procedures.

[0040] Specifically, both the front housing 2 and the rear housing 3 have arc-shaped sections on their opposite edges. After the front housing 2 and the rear housing 3 are joined together, the two arc-shaped sections form a mounting position, on which a side panel 6 for maintenance and disassembly is detachably installed. This mounting position is ingeniously designed, providing users with an easily accessible and operable maintenance space. A side panel 6 is detachably installed in this mounting position, connected to the front housing 2 and the rear housing 3 by simple clips, screws, or other fixing methods. When users need to perform internal maintenance or cleaning, they can easily remove this side panel 6 to quickly access the dryer's interior without disassembling the entire machine, greatly saving maintenance time and costs.

[0041] Furthermore, this design makes the dryer's internal structure clearer and easier to maintain. Users can visually observe the various components and connections inside the machine by disassembling side panel 6, making it easier to diagnose and resolve potential problems. At the same time, the removability of side panel 6 also provides users with the convenience of replacing or upgrading internal components, allowing the dryer to more flexibly adapt to different usage needs.

[0042] Optionally, the rear housing 3 includes a connecting part 301 and a splicing part 302. The splicing part 302 is mounted above the chassis 1 via the connecting part 301, and the splicing part 302 is joined with the front housing 2. The connecting part 301, as the main supporting structure of the rear housing 3, is firmly mounted above the chassis 1. It bears the important responsibility of firmly connecting the rear housing 3 to the chassis 1, ensuring the stability and safety of the dryer during operation. The connecting part 301 is typically connected to the chassis 1 using bolts, clips, or other reliable fixing methods to ensure the strength and durability of the connection. The splicing part 302 is the key part that joins with the front housing 2. It is custom-designed according to the shape and size of the front housing 2 to ensure that the two can be joined tightly and stably. During the splicing process, the splicing part 302 and the edge of the front housing 2 are precisely positioned and fixed through guide grooves 402, clips, bolts, or other connecting structures. This design not only simplifies the assembly process and improves assembly efficiency, but also ensures the flatness and aesthetics of the dryer's outer casing. Dividing the rear casing 3 into a connecting part 301 and a splicing part 302 also facilitates maintenance and upgrades. When users need to repair or replace the rear casing 3, they can easily remove the entire rear casing 3 by simply disassembling the connecting part 301, without having to disassemble the entire dryer. This significantly saves maintenance time and costs, and improves user satisfaction.

[0043] Preferably, the contact surfaces of the guide portion 401 and the guide groove 402 are coated with a wear-resistant coating. The wear-resistant coating is a special material that effectively reduces wear during friction, thereby extending the service life of the components. After applying the wear-resistant coating to the contact surfaces of the guide portion 401 and the guide groove 402, even under frequent friction and pressure during use, the flatness and precision of the contact surfaces can be maintained, ensuring that the guide portion 401 and the guide groove 402 can always fit tightly together, achieving a stable guiding function. The wear-resistant coating also improves the corrosion resistance and anti-aging properties of the guide portion 401 and the guide groove 402. During the operation of the dryer, changes in temperature and humidity inside the machine may have a certain impact on the components; the presence of the wear-resistant coating can effectively isolate these adverse factors, protecting the guide portion 401 and the guide groove 402 from corrosion and aging.

[0044] In some embodiments, the chassis 1 is provided with a drainage structure and a heat dissipation structure. The main function of the drainage structure is to collect and drain the moisture generated during the operation of the dryer. This moisture may originate from the condensation process, washing residue, or other factors. A well-designed drainage structure can ensure that moisture is drained in a timely and effective manner, thereby avoiding machine malfunctions or performance degradation caused by water accumulation. Providing a drainage structure on the chassis 1 allows for convenient guidance of moisture to designated drain outlets or drain pipes, ensuring the dryer's interior remains dry and clean.

[0045] The heat dissipation structure is used to dissipate the heat generated during the operation of the dryer. When the dryer is working, components such as the motor and compressor generate a significant amount of heat. If this heat cannot be dissipated in time, it will cause the machine to overheat, affecting its performance and lifespan. Therefore, by incorporating heat dissipation structures, such as ventilation holes and heat sinks, into the chassis 1, heat can be effectively dissipated, maintaining a stable internal temperature for the dryer. This not only helps improve the dryer's operating efficiency but also extends its lifespan.
