Technical Field

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

[0002] With the improvement of living standards, clothes dryers have entered more and more ordinary families and become one of the essential household appliances for high-quality life. It uses an electric motor to drive a drum to rotate, thereby continuously lifting and dropping clothes, and making hot air blown by a compressor heat pump or an electric heater pass through the clothes to evaporate and then condense and separate the moisture to dry the clothes.

[0003] With the development of science and technology, a steam washing function has gradually been added to clothes dryers (steam washing is to wash clothes with a large amount of steam, allowing the steam to penetrate deep into the clothes fibers to effectively remove stains on the clothes). However, due to the small steam generation power of the steam engine in the clothes dryer and the small total amount of steam, the generated steam is not enough to effectively dry and wash the clothes in the washing machine, and the stains and residual laundry detergent on the clothes cannot be thoroughly cleaned. Utility Model Content

[0004] The purpose of the embodiments of this application is to provide a clothes dryer that can generate a large amount of steam to thoroughly clean the stains and residual laundry detergent on clothes before drying the clothes, ensuring that the clothes after subsequent drying can maintain a high level of cleanliness.

[0005] To achieve the above object, this application adopts the following technical solutions:

[0006] On the one hand, a clothes dryer is provided, including: a first support frame, a second support frame, a plurality of connecting plates, a drum, a hot air generating component, and a steam generating component. The first support frame and the second support frame are arranged opposite to each other, and an installation space for installing the drum is defined between them. The plurality of connecting plates are sequentially and spacedly connected between the first support frame and the second support frame. The hot air generating component is installed on the second support frame. An air inlet is provided on one side of the drum relative to the second support frame, and the air inlet is connected to the hot air generating component through a pipeline.

[0007] An installation groove is provided on one of the connecting plates. The steam generating component includes an installation member, a main body member, an evaporation tube, and a superconducting heating layer. Convex strips that are matched and embedded with the installation groove are convexly provided on both side surfaces of the installation member. The main body member is installed on the installation member. The evaporation tube is arranged inside the main body member. The superconducting heating layer covers the outer periphery of the evaporation tube. The evaporation tube has a water inlet end and an air outlet end. The water inlet end is connected to a water supply device through a pipeline, and the air outlet end inputs steam into the drum through a pipeline.

[0008] Further, an air inlet is provided on one side of the drum relative to the first support frame, and the air inlet is connected to the air outlet end through a pipeline.

[0009] Further, the evaporation tube includes a plurality of straight tubes arranged at intervals and elbows connecting between adjacent two straight tubes, and the superconducting heating layer is coated on the outer periphery of the plurality of straight tubes.

[0010] Further, electrodes are sleeved at both ends of the superconducting heating layer in the length direction, and the electrodes are connected to the controller through conductive wires.

[0011] Further, a gap of 1 cm - 3 cm is left between the electrode and the inner wall of the main body member.

[0012] Further, the main body member includes a bottom shell and a cover plate slidably mounted on the bottom shell, and an installation cavity is defined between the bottom shell and the cover plate, and the evaporation tube and the superconducting heating layer are both arranged in the installation cavity.

[0013] Further, a guiding groove is provided on the inner peripheral wall of the bottom shell, and the cover plate is fitted in the guiding groove and can reciprocate between an open position and a closed position along the guiding groove.

[0014] Further, a limiting plate is convexly provided on the connecting plate, and the limiting plate abuts against and limits the installation member.

[0015] Further, the superconducting heating layer is made of a titanium-nickel alloy or an aluminum-chromium alloy material.

[0016] Further, the installation member is locked to the connecting plate by screws or bolts.

[0017] The beneficial effects of the present application are as follows: The main body frame is formed by the relative arrangement of the first support frame and the second support frame, and a space for installing the drum is formed between the two, and the structural stability is strengthened by a plurality of connecting plates. An air inlet is provided on one side of the drum and is connected to the hot air generating assembly installed on the second support frame to ensure that hot air can smoothly enter the drum. An integrated steam generating assembly is installed in the installation groove on the connecting plate, and the protrusions of the installation member are closely matched with the installation groove to achieve stable installation. The core of the steam generating assembly includes a main body member, an evaporation tube and a superconducting heating layer. The evaporation tube is placed inside the main body member and has a water inlet end and an air outlet end. The water inlet end is connected to a water supply device through a pipeline to continuously supply water source. The superconducting heating layer closely covers the outer periphery of the evaporation tube, and uses its excellent heat conduction performance to quickly heat the water in the evaporation tube to boiling to generate a large amount of steam. These steams then pass through the air outlet end and are directly transported to the inside of the drum through the pipeline.

[0018] During the drying process, steam first enters the drum. Utilizing its powerful penetration ability, it deeply penetrates into the clothing fibers, effectively dissolving and loosening the stains and residual laundry detergent on the clothes, achieving deep cleaning. Subsequently, the hot air generating component starts, and the generated high-temperature hot air enters through the air inlet of the drum, fully contacting the clothes, and quickly taking away the moisture on the clothes, achieving efficient drying. The perfect combination of steam cleaning and hot air drying not only significantly improves the cleanliness of the clothes but also greatly shortens the drying time, bringing a more convenient and efficient clothing processing experience to users.

[0027] To make the technical problems solved by the present application, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of the present application are further described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

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 communication inside 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 application can be understood according to specific circumstances.

[0029] In the present application, unless otherwise clearly defined 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", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0030] As Figures 1-6 shown in the figure, this embodiment provides a clothes dryer, including: a first support frame 1, a second support frame 2, a plurality of connecting plates 3, a drum 4, a hot air generating assembly, and a steam generating assembly 5. The first support frame 1 and the second support frame 2 are arranged opposite to each other, and an installation space for installing the drum 4 is defined therebetween. A plurality of the connecting plates 3 are sequentially and spacedly connected between the first support frame 1 and the second support frame 2. The hot air generating assembly is installed on the second support frame 2. An air inlet is formed on one side of the drum 4 relative to the second support frame 2, and the air inlet is connected to the hot air generating assembly through a pipeline.

[0031] An installation groove 301 is formed on one of the connecting plates 3. The steam generating assembly 5 includes an installation member 501, a main body member 502, an evaporation pipe 503, and a superconducting heating layer 504. Convex strips 5011 that are matched and embedded with the installation groove 301 are convexly provided on both side surfaces of the installation member 501. The main body member 502 is installed on the installation member 501. The evaporation pipe 503 is arranged inside the main body member 502. The superconducting heating layer 504 covers the outer periphery of the evaporation pipe 503. The evaporation pipe 503 has a water inlet end and an air outlet end. The water inlet end is connected to a water supply device through a pipeline, and the air outlet end inputs steam into the drum 4 through a pipeline.

[0032] Based on the above solution, the main frame is formed by the relative arrangement of the first support frame 1 and the second support frame 2. A space for installing the drum 4 is formed between the two, and the structural stability is strengthened by a plurality of connecting plates 3. An air inlet is provided on one side of the drum 4 and is connected to the hot air generating component installed on the second support frame 2 to ensure that hot air can smoothly enter the drum 4. A set of steam generating component 5 is integrated, and this component is installed in the installation groove 301 on the connecting plate 3, and is firmly installed by the close fit of the rib 5011 of the mounting member 501 and the installation groove 301. The core of the steam generating component 5 includes a main body member 502, an evaporation tube 503 and a superconducting heating layer 504. The evaporation tube 503 is built into the main body member 502 and has a water inlet end and an air outlet end. The water inlet end is connected to a water supply device through a pipeline to continuously supply water. The superconducting heating layer 504 closely covers the outer periphery of the evaporation tube 503. Using its excellent heat conduction performance, the water in the evaporation tube 503 is quickly heated to boiling to generate a large amount of steam. These steams then pass through the air outlet end and are directly transported to the inside of the drum 4 through a pipeline. During the drying process, the steam first enters the drum 4, uses its strong penetration to penetrate into the clothing fibers, effectively dissolves and loosens the stains and residual laundry detergent on the clothes, and realizes deep cleaning. Subsequently, the hot air generating component is started, and the generated high-temperature hot air enters through the air inlet of the drum 4, fully contacts the clothes, and quickly takes away the moisture on the clothes to achieve efficient drying. The perfect combination of steam cleaning and hot air drying not only significantly improves the cleanliness of the clothes, but also greatly shortens the drying time, bringing a more convenient and efficient clothing processing experience for users.

[0033] In addition, this clothes dryer also has the advantages of energy conservation and environmental protection. The application of the superconducting heating layer 504 effectively improves the heating efficiency and reduces the energy consumption. At the same time, compared with traditional water washing, the steam cleaning method can significantly reduce the use of water resources and the discharge of waste water, meeting the pursuit of modern families for a green life. In summary, the clothes dryer of the embodiment of the present application, with its innovative design concept, efficient function integration and environmental protection characteristics, provides strong support for high-quality life.

[0034] Further, an air inlet is provided on one side of the drum 4 relative to the first support frame 1, and the air inlet is connected to the air outlet end through a pipeline. After the steam is released from the air outlet end of the evaporation tube 503, it is immediately guided to the air inlet of the drum 4 through a special pipeline system. After entering the drum 4, the steam quickly diffuses and is evenly distributed among the clothes. Using its strong permeability and dissolving ability, it penetrates into the clothing fibers and effectively removes stains and residual laundry detergent. At the same time, the flow of the steam can also help the clothes to unfold better, increasing the contact area with the hot air and further improving the drying effect.

[0035] Meanwhile, the direct connection between the air inlet of the drum 4 and the steam outlet end also reduces the energy loss during steam transmission and improves the energy efficiency of the overall system. This design not only optimizes the utilization efficiency of steam but also simplifies the pipeline layout, making the internal structure of the dryer more compact and reasonable.

[0036] In some embodiments, to further improve the steam generation efficiency and uniformity, the evaporation tube 503 in the clothes dryer adopts a more refined and efficient design. Specifically, the evaporation tube 503 consists of multiple straight tubes 5031 arranged at intervals. These straight tubes 5031 are arranged in an orderly manner, forming a structure similar to an array. The adjacent straight tubes 5031 are connected by elbow joints 5032 to ensure that steam can flow smoothly throughout the evaporation tube 503 and avoid the formation of dead ends. The superconducting heating layer 504 is closely and evenly coated on the outer periphery of these straight tubes 5031. Due to the interval setting between the straight tubes 5031, the superconducting heating layer 504 can transfer heat to the water in the evaporation tube 503 more directly and effectively, accelerating the boiling process of the water and thus generating more steam. At the same time, this design also helps to reduce heat dissipation and improve the heating efficiency. The design of the elbow joint 5032 not only ensures the continuity of steam flow but also plays a certain buffering role, preventing excessive impact force and noise generated during steam flow. In addition, the elbow joint 5032 can adjust the angle and position according to actual needs to adapt to different installation environments and steam transmission requirements.

[0037] It should be noted that electrodes 505 are sleeved at both ends of the superconducting heating layer 504 along the length direction, and the electrodes 505 are connected to the controller through conducting wires. The main function of the electrodes 505 is to serve as the input and output points of the current. Through them, the controller can supply electrical energy to the superconducting heater, making it heat up and heat the water in the evaporation tube 503. The electrodes 505 are usually made of materials with good electrical conductivity, such as copper, aluminum, or silver, etc., to ensure that the current can flow smoothly. The conducting wires are responsible for connecting the electrodes 505 to the controller to form a complete circuit. The controller can precisely control the heat generation of the heater by adjusting the magnitude and time of the current passing through the superconducting heater, thereby achieving precise control of the steam generation amount. In addition, to ensure the safety and stability of the circuit, appropriate protection components, such as fuses and overcurrent protectors, need to be added to the circuit to prevent equipment damage or safety accidents caused by excessive current or short circuits.

[0038] To ensure heating efficiency and electrical safety, it is preferred to sleeved the electrodes 505 at both ends along the length direction of the superconducting heater, and ensure that there is a gap of 1 cm to 3 cm between these electrodes 505 and the inner wall of the main body 502. Such a design not only provides sufficient heat dissipation space for the heat generated by the electrodes 505 and the heater during operation, effectively preventing local overheating, but also enhances electrical insulation protection and reduces the risk of short circuits and other electrical faults. At the same time, the appropriate gap also facilitates subsequent maintenance or replacement of the electrodes 505, improving the maintainability of the equipment. In addition, this design also takes into account the impact of different working environments and operating conditions on the performance of the equipment. Through reasonable gap setting, the steam generating assembly 5 can maintain stable performance output within a wider range of operating conditions.

[0039] Further, the main body 502 includes a bottom shell 5021 and a cover plate 5022 slidably mounted on the bottom shell 5021. An installation cavity is defined between the bottom shell 5021 and the cover plate 5022, and both the evaporation tube 503 and the superconducting heating layer 504 are disposed in the installation cavity. In order to improve the flexibility and maintainability of the assembly, a design solution combining the bottom shell 5021 and the cover plate 5022 is adopted. Specifically, the main body 502 consists of two parts: the bottom shell 5021 and the cover plate 5022 slidably mounted thereon. The bottom shell 5021 serves as the basic part of the main body 502, providing a stable support structure; while the cover plate 5022 is tightly connected to the bottom shell 5021 by means of sliding installation, and an installation cavity is defined between the two. This installation cavity is the core area of the steam generating assembly 5, and both the evaporation tube 503 and the superconducting heating layer 504 are disposed therein. The evaporation tube 503 is composed of a plurality of linearly arranged tubes 5031 spaced apart from each other and turning heads 5032 connected between adjacent linearly arranged tubes 5031, and is responsible for guiding the water flow to the heating area and generating steam. The superconducting heating layer 504 is tightly wrapped around the outer periphery of the linearly arranged tubes 5031 of the evaporation tube 503, and uses its excellent heat conduction performance to convert electrical energy into heat energy, quickly heating the water in the evaporation tube 503 to the boiling state, thereby generating a large amount of steam. Through the design of the slidably mounted cover plate 5022, users can conveniently open or close the installation cavity to perform maintenance, replacement or repair on the internal evaporation tube 503 and superconducting heating layer 504. This design not only improves the maintainability of the steam generating assembly 5, but also makes the entire clothes dryer more flexible and convenient to use.

[0040] Furthermore, a guiding groove 5023 is formed on the inner peripheral wall of the bottom case 5021, and the cover plate 5022 is fitted in the guiding groove 5023 and can reciprocate between an open position and a closed position along the guiding groove 5023. When the cover plate 5022 is in the installed state, it slides along the trajectory of the guiding groove 5023. This design not only ensures the smoothness and fluency of the movement of the cover plate 5022, but also avoids problems such as poor sealing or damage caused by deviation or shaking. Users can, through simple operations such as pushing or pulling the cover plate 5022, make it reciprocate between the open position and the closed position along the guiding groove 5023. In the open position, users can conveniently access the evaporation tube 503 and the superconducting heating layer 504 in the installation cavity for necessary repair, replacement or maintenance work; while in the closed position, the cover plate 5022 closely fits on the bottom case 5021 to ensure the sealing of the installation cavity and prevent steam or heat leakage.

[0041] Optionally, a limiting plate 302 protrudes from the connecting plate 3, and the limiting plate 302 abuts against and limits the installation part 501. When the installation part 501 is installed on the connecting plate 3, its edge or specific part will be in close contact with the limiting plate 302. This contact not only restricts the movement of the installation part 501 in the horizontal direction, but also prevents the installation part 501 from shaking or falling off in the vertical direction through friction or other physical effects. Therefore, the abutting and limiting relationship between the limiting plate 302 and the installation part 501 provides a solid foundation for the stable operation of the entire steam generating assembly 5 and even the entire dryer.

[0042] In addition, the design of the limiting plate 302 also has a certain degree of flexibility and adjustability. According to specific installation requirements and space limitations, the position, quantity or shape of the limiting plate 302 can be adjusted to adapt to different installation environments and working conditions. This flexibility in design makes the clothes dryer more convenient and efficient in the manufacturing and installation processes.

[0043] In the steam generating assembly 5 of the clothes dryer, the superconducting heating layer 504, as one of the key components, has an important impact on aspects such as heating efficiency, durability, and safety. Specifically, we have selected two materials, titanium-nickel alloy or aluminum-chromium alloy, to fabricate the superconducting heating layer 504. Titanium-nickel alloy is renowned for its excellent high-temperature resistance, corrosion resistance, and good thermal conductivity. In a high-temperature environment, the titanium-nickel alloy can maintain stable physical and chemical properties and is not prone to deformation or damage. At the same time, its excellent thermal conductivity enables heat to be transferred quickly and evenly to the evaporation tube 503, thereby improving the heating efficiency and shortening the steam generation time. In addition, the titanium-nickel alloy also has good fatigue resistance and a long service life, which can ensure the long-term stable operation of the steam generating assembly 5. Another optional material is aluminum-chromium alloy. Aluminum-chromium alloy also has excellent thermal conductivity and good corrosion resistance. Compared with the titanium-nickel alloy, the cost of aluminum-chromium alloy may be more economical, and it also meets the requirements of the steam generating assembly 5 for heating efficiency and durability to a certain extent. However, in specific applications, we need to select the most suitable material according to actual needs and environmental conditions.

[0044] In some embodiments, the mounting member 501 is locked to the connecting plate 3 by screws or bolts. Threaded holes or mounting holes matching the screws or bolts are preset on the mounting member 501. During assembly, the screws or bolts are passed through the holes reserved on the connecting plate 3 and screwed into the threaded holes or mounting holes of the mounting member 501. By tightening the screws or bolts, sufficient clamping force can be generated to form a tight and stable connection between the mounting member 501 and the connecting plate 3. This fixing method of locking with screws or bolts has multiple advantages. First of all, it is simple and easy to implement, and no complex tools or equipment are required to complete the assembly. Secondly, the tightening force of the screws or bolts can be adjusted according to needs to ensure the stability between the mounting member 501 and the connecting plate 3. In addition, since screws and bolts are commonly used fasteners, their cost is relatively low, and they are easy to obtain and replace. In addition to locking with screws or bolts, other fixing methods, such as welding and riveting, can also be selected according to specific needs. However, in the assembly of the clothes dryer, locking with screws or bolts has become a widely adopted fixing method due to its simplicity and reliability.
