[0001] The present application relates to the technical field of washing and drying integrated machines, and particularly relates to an air exhaust device of a washing and drying integrated machine. BACKGROUND

[0002] In modern family life, a washing and drying integrated machine as a convenient household appliance combines the functions of washing and drying, greatly facilitating people's daily clothes processing. In the drying process, in order to prevent lint and other impurities from being discharged with air, a filter device is usually arranged in the drying air exhaust pipe. However, after a long time of use, a large amount of lint will gradually accumulate on the filter device. As the lint continues to accumulate, the air permeability of the filter device is seriously affected, leading to poor air exhaust, which not only reduces the drying efficiency, but also may adversely affect the normal operation of the machine, even increases energy consumption, and shortens the service life of the equipment.

[0003] More troublesome is that most washing and drying integrated machines on the market need manual operation when cleaning the filter device. The user must disassemble the washing machine part to access and remove the filter device for cleaning. This process is not only complicated and requires certain technical and tool support, but also has certain safety hazards, increases the user's maintenance cost and use burden, and greatly affects the user experience.

[0030] 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.

[0031] 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 utility model based on the specific circumstances.

[0032] 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.

[0033] In modern family life, washer-dryer combos are a convenient household appliance that combines washing and drying functions, greatly simplifying daily clothing handling. During the drying process, to prevent lint and other impurities from being expelled with the air, a filter is usually installed in the drying exhaust duct. However, after prolonged use, a large amount of lint gradually accumulates on the filter. As the lint accumulates, the filter's permeability is severely affected, leading to poor ventilation. This not only reduces drying efficiency but may also adversely affect the normal operation of the machine, even increasing energy consumption and shortening the equipment's lifespan.

[0034] What's even more problematic is that most washer-dryer combos on the market require manual operation to clean the filter. Users must disassemble the washing machine to access and remove the filter for cleaning. This process is not only tedious and complicated, requiring certain technical skills and tools, but also poses certain safety hazards, increasing users' maintenance costs and burden, and greatly affecting the user experience.

[0035] To overcome the above technical problems, such as Figures 1-8 As shown, this embodiment provides an exhaust device for a washer-dryer combo, including:

[0036] The filter 3 includes a mounting frame 31, a filter screen 32, and a drive assembly 33. The filter screen 32 is rotatably mounted in the mounting frame 31. The drive assembly 33 is connected to the filter screen 32 in a transmission manner. The drive assembly 33 can drive the filter screen 32 to rotate 180° within the mounting frame 31 to change the windward and leeward sides of the filter screen 32.

[0037] The first exhaust pipe 1 and the second exhaust pipe 2 are respectively connected to two opposite sides of the mounting frame 31. The end of the first exhaust pipe 1 away from the mounting frame 31 is connected to the exhaust port of the washing tub, and the end of the second exhaust pipe 2 away from the mounting frame 31 is used to exhaust air outward.

[0038] During normal operation, the filter surface of filter 3 faces the first exhaust duct 1, intercepting lint in the exhaust air. When cleaning filter 32 is required, the control center of the washer-dryer uses drive component 33 to rotate filter 32 180°, making the filter surface of filter 3 the leeward side. Then, the drying ventilation function is activated, using ventilation to blow the lint intercepted on the filter surface towards the second exhaust duct 2 and discharge it outwards. Depending on actual usage, during cleaning, the user can insert the exhaust end of the second exhaust duct 2 into water to intercept lint, or cover the exhaust end of the second exhaust duct 2 with a filter bag to prevent lint from flying around.

[0039] Based on the exhaust device provided in this embodiment, the filter screen 32 is rotated 180° by the drive component 33, making the filter surface the leeward side. The ventilation function then blows the trapped lint towards the second exhaust pipe 2 and discharges it outwards, effectively solving the problem of easy clogging of filters in traditional washer-dryer combos, which affects exhaust and equipment operation. Regular automatic cleaning of the filter screen 32 maintains its good air permeability, ensuring smooth exhaust, thereby improving drying efficiency, reducing energy consumption, and extending equipment lifespan. Importantly, cleaning can be completed without manual disassembly of the washing machine, greatly simplifying the cleaning process, reducing user maintenance costs and burden, and improving user experience.

[0040] In one embodiment, reference is made to Figures 3-4 The filter screen 32 is provided with an upper support shaft 321 and a lower support shaft 322 on its upper and lower sides, respectively. The top and bottom of the mounting frame 31 are provided with an upper mounting hole 311 and a lower mounting hole 312, respectively. The upper support shaft 321 and the lower support shaft 322 are rotatably inserted into the upper mounting hole 311 and the lower mounting hole 312, respectively.

[0041] By providing an upper support shaft 321 and a lower support shaft 322 on the upper and lower sides of the filter screen 32 respectively, and providing upper mounting holes 311 and lower mounting holes 312 on the top and bottom of the mounting frame 31 respectively, the upper support shaft 321 and lower support shaft 322 can be rotatably inserted into the mounting holes. This not only provides a stable support for the filter screen 32, ensuring that it will not shake or shift during operation, but also, because the cooperation between the support shaft and the mounting hole is rotatable, the filter screen 32 can be flipped more smoothly and flexibly, reducing friction and wear between mechanical parts, thereby improving the service life and reliability of the entire device.

[0042] In one embodiment, the upper mounting hole 311 is a through hole, the drive assembly 33 is mounted above the mounting frame 31, and the upper support shaft 321 extends above the mounting frame 31 and is connected to the drive assembly 33 in a transmission manner.

[0043] The upper mounting hole 311 is designed as a through hole, which allows the upper support shaft 321 to extend to the top of the mounting frame 31 and to achieve a transmission connection with the drive component 33 installed on the top of the mounting frame 31. This layout makes full use of the vertical space and avoids the space occupation problem caused by installing the drive component 33 inside or on the side of the mounting frame 31. This makes the structure of the entire exhaust device more compact and ensures the smoothness of the filter screen 32 flipping process.

[0044] In one embodiment, a protective cover 34 is also installed on the top of the mounting frame 31, and the protective cover 34 covers the drive assembly 33.

[0045] A protective cover 34 is installed on the top of the mounting frame 31 to cover the drive assembly 33, which can effectively prevent dust, moisture and other impurities from entering the drive assembly 33. This not only reduces the risk of drive assembly 33 failure caused by external factors, but also improves the equipment's adaptability to harsh environments and enhances the reliability and stability of the entire exhaust device.

[0046] In one embodiment, reference is made to Figure 7 The drive assembly 33 includes a motor 331 and a reduction gear, wherein the motor 331 is rotatably connected to the upper support shaft 321 through the reduction gear.

[0047] Motor 331 serves as the power source, and is rotatably connected to the upper support shaft 321 via a reduction gear. This configuration allows for precise control of the flipping speed and angle of the filter screen 32, ensuring that the filter screen 32 smoothly and accurately completes a 180° rotation during the flipping process, achieving accurate switching between the windward and leeward sides. The addition of the reduction gear also adjusts the high speed of motor 331 to a low speed suitable for the flipping of the filter screen 32, providing sufficient torque, making the transmission process more efficient and stable, and enhancing the reliability of equipment operation.

[0048] The speed reduction component can be a gear drive, a worm gear drive structure, or the like.

[0049] The drive assembly 33 can be equipped with a power-off self-locking structure to ensure that the filter 32 remains stable during the dormant process. In specific implementation, the motor 331 can be a power-off self-locking motor 331, or a locker can be set in the reduction component. When the motor 331 is powered on, the locker unlocks, and when the motor 331 is powered off, the locker locks the reduction component; or the reduction component can be a worm gear transmission structure with a self-locking function.

[0050] In one embodiment, the filter screen 32 is provided with flexible sealing strips 323 on its left and right sides, and the flexible sealing strips 323 abut against the inner sidewall of the mounting frame 31.

[0051] Flexible sealing strips 323 are provided on the left and right sides of the filter screen 32 and abut against the inner side wall of the mounting frame 31. This can effectively prevent impurities such as lint from leaking from the side edges of the filter screen 32, ensuring that impurities in the exhaust air can only be filtered and intercepted through the front of the filter screen 32.

[0052] Importantly, the flexible sealing strip 323 has a variability capability. During the flipping process of the filter screen 32, the flexible sealing strip 323 can undergo flexible deformation, which makes the filter screen 32 flip smoothly. This deformation capability not only does not affect the normal flipping of the filter screen 32, but also can quickly restore the sealed state after flipping, ensuring that the filtration effect is not affected.

[0053] In one embodiment, the inner wall of the mounting frame 31 is further provided with a flexible sealing frame 35, one side of which abuts against the perimeter of the filter screen 32.

[0054] The flexible sealing frame 35 abuts against the filter screen 32 around its perimeter, effectively preventing impurities such as lint from leaking from the edges of the filter screen 32. This ensures that impurities in the exhaust air can only be filtered and intercepted through the front of the filter screen 32, thereby improving the filtration effect and exhaust quality. The flexible sealing frame 35 is adaptable; it can flexibly deform during the flipping process of the filter screen 32, allowing the filter screen 32 to flip smoothly. This deformation capability not only does not affect the normal flipping of the filter screen 32 but also allows it to quickly return to a sealed state after flipping, ensuring that the filtration effect is not affected.

[0055] In one embodiment, the inner wall of the mounting frame 31 is provided with a mounting groove 313, and the four sides of the flexible sealing frame 35 are embedded in the mounting groove 313.

[0056] By setting mounting grooves 313 on the inner wall of mounting frame 31 and embedding the flexible sealing frame 35 around its perimeter, the stable installation of the flexible sealing frame 35 is ensured. This installation method not only ensures a tight fit between the flexible sealing frame 35 and mounting frame 31, enhancing the sealing performance, but also effectively prevents the flexible sealing frame 35 from shifting or falling off during use, ensuring a consistent sealing effect around the filter screen 32.

[0057] In addition, the embedded installation method is relatively simple. The installation can be completed by accurately embedding the flexible sealing frame 35 into the mounting slot 313 without complicated tools or cumbersome steps. During maintenance, if the flexible sealing frame 35 needs to be replaced, it can be easily removed from the mounting slot 313, which facilitates quick replacement and cleaning, reducing maintenance difficulty and time costs.

[0058] In one embodiment, the border strip of the flexible sealing frame 35 is a hollow tube.

[0059] The hollow tubular structure gives the frame strip better flexibility and deformability. During the flipping process of the filter screen 32, the frame strip can more easily undergo flexible deformation to adapt to the flipping action of the filter screen 32, ensuring the smooth progress of the flipping process. At the same time, it can quickly return to its original shape after flipping to maintain a good sealing effect.

[0060] In one embodiment, the first exhaust pipe 1 is provided with a first flange plate 11 at one end connected to the mounting frame 31, and the second exhaust pipe 2 is provided with a second flange plate 21 at one end connected to the mounting frame 31. The first flange plate 11 and the second flange plate 21 are respectively connected and fixed to the mounting frame 31 by screws.

[0061] The flange plate is fixed to the mounting frame 31 with screws. This connection method provides strong mechanical strength and stability, ensuring that the first exhaust pipe 1 and the second exhaust pipe 2 will not loosen or fall off due to vibration or other external forces during equipment operation, thus guaranteeing the stable operation of the entire exhaust system. To prevent air leakage, sealing rings can be installed on both sides of the mounting frame 31.
