Description

Technical Field

[0001] This application relates to the technical field of washer-dryer combos, and more particularly to a filtration device for an washer-dryer combo and the washer-dryer combo itself. Background Technology

[0002] 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.

[0003] 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.

[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.

[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, this embodiment provides a filter device for a washer-dryer combo, which can be installed in the exhaust system of the washer-dryer combo, can filter lint in the exhaust air, and also has the function of automatically cleaning the filter screen 2.

[0036] like Figures 1-6 As shown, the filtration device in this embodiment includes:

[0037] Ventilation pipe 1 has a ventilation cavity inside, and a drain hole 11 is provided at the bottom of the ventilation pipe 1;

[0038] Filter 2 is installed inside the ventilation cavity to filter exhaust air;

[0039] The rinsing mechanism 3 is disposed within the ventilation cavity on the leeward side of the filter screen 2; it includes a lifting assembly 32, a mounting rod 31, a water supply pipe, and nozzles 33. The mounting rod 31 extends horizontally and is connected to the lifting assembly 32, allowing the mounting rod 31 to move up and down. Multiple nozzles 33 are spaced along the length of the mounting rod 31, each nozzle 33 being connected to the water supply pipe and facing the filter screen 2.

[0040] A water collection cover 5 is installed below the ventilation pipe 1 to collect water discharged from the drain hole 11; the water collection cover 5 also includes a drain pipe 51 for connecting to the drainage system of the washer-dryer combo.

[0041] The water supply pipe of the rinsing mechanism 3 can be connected to a tap water supply. An electrically controlled valve is installed in the water supply pipe, controlled by the control center of the washer-dryer combo. When the filter screen 2 needs cleaning, the water supply of the rinsing mechanism 3 and the drive of the lifting assembly 32 are activated. The nozzles 33 can then spray the lint from the windward side of the filter screen 2 from the leeward side. The lifting assembly 32 can drive all the nozzles 33 to move up and down to achieve vertical sweeping, thus achieving a thorough cleaning of the filter screen 2. The water containing lint after washing is collected through the water collection hood 5 and finally discharged from the drainage system.

[0042] Based on the filtration device provided in this embodiment, the filter screen 2 can be thoroughly cleaned through the reverse rinsing of the nozzle 33 and the up-and-down movement of the lifting component 32, effectively removing accumulated lint and other impurities. Compared with traditional manual cleaning, this method is more efficient and provides better cleaning results. Timely and effective cleaning maintains the good air permeability of the filter screen 2, preventing machine malfunctions caused by poor ventilation, reducing energy consumption, and extending the service life of the washer-dryer combo. Furthermore, ensuring unobstructed ventilation helps improve drying efficiency, shorten drying time, and enhance drying effects, further improving the user experience. Importantly, during the cleaning of the filter screen 2, the user does not need to manually disassemble the washer-dryer combo, reducing the tediousness and technical requirements of manual operation, lowering maintenance costs and user burden, and improving the user experience.

[0043] In one embodiment, reference is made to Figure 1 A spray pipe 4 is also horizontally arranged inside the ventilation cavity. The spray pipe 4 is located on the windward side of the filter screen 2 and is arranged near the top of the filter screen 2. The spray pipe 4 is used to spray the filter screen 2.

[0044] The spray pipe 4 is located at the top of the windward side of the filter screen 2. During cleaning, the lint on the filter screen 2 is first flushed away by the rinsing mechanism 3 on the leeward side. Then, the rinsing mechanism 3 is turned off and the spray pipe 4 is turned on, spraying water from the top of the windward side of the filter screen 2. This allows the water to flow down the filter screen 2, effectively removing any remaining lint adhering to the windward side, thus achieving a secondary cleaning of the filter screen 2 and ensuring it is cleaner and more thorough. It is understood that an electrically controlled valve is installed in the pipeline to automatically control the opening and closing of the spray pipe 4.

[0045] In this embodiment, the spray pipe 4 makes the cleaning process more efficient. After the rinsing mechanism 3 completes the initial cleaning, the spray pipe 4 can quickly rinse the windward side of the filter screen 2 without additional manual intervention or complicated operating procedures, saving cleaning time and improving the efficiency of the entire cleaning process. Since the entire cleaning process is automated, users do not need to manually disassemble the washer-dryer to clean the filter screen 2, reducing the difficulty and workload of manual maintenance, and also reducing the risk of equipment damage caused by improper manual cleaning, thereby reducing maintenance costs.

[0046] In one embodiment, the spray pipe 4 is provided with a plurality of spray holes facing the filter screen 2 along its own length direction.

[0047] Multiple spray holes can spray water more evenly on the windward side of the filter screen 2. The even distribution of the spray holes allows water to cover a large area of ​​the filter screen 2 at the same time, ensuring that the entire surface of the filter screen 2 can be effectively rinsed, thereby more thoroughly removing adhering lint and other impurities and improving the cleaning effect.

[0048] In one embodiment, reference is made to Figure 6 The lifting assembly 32 includes a lead screw 321, a nut 322, and a motor 323. The motor 323 is connected to the lead screw 321 for transmission. The nut 322 is threaded onto the lead screw 321. One end of the mounting rod 31 is fixedly connected to the nut 322. The motor 323 drives the lead screw 321 to rotate, so that the nut 322 drives the mounting rod 31 to rise and fall.

[0049] The motor 323 drives the lead screw 321 to rotate, and the nut 322 moves up and down along the lead screw 321, thereby driving the mounting rod 31 and the nozzle 33 to perform precise lifting and lowering movements. The transmission method of the lead screw 321 and the nut 322 has high stability and reliability, ensuring that the mounting rod 31 remains stable during lifting and lowering, avoiding poor cleaning effect or equipment damage due to vibration or deviation. The use of the motor 323 realizes the automated control of the lifting component 32, which is centrally managed by the control center of the washer-dryer, requiring no manual intervention, thus improving the intelligence level of the equipment and the user experience.

[0050] In one embodiment, the top end of the lead screw 321 extends above the ventilation pipe 1, and the motor 323 is disposed above the ventilation pipe 1 for transmission connection with the lead screw 321.

[0051] Placing the motor 323 above the ventilation duct 1 has at least the following advantages: it avoids taking up extra space inside or below the ventilation duct 1, making the overall structure more compact and facilitating a more rational layout of the internal space of the washer-dryer combo; it makes installation and disassembly more convenient, allowing maintenance personnel to easily access the motor 323 for maintenance or replacement without the need for complex operations inside the ventilation duct 1; and it maintains a certain distance from the high-temperature and humid environment inside the ventilation duct 1, reducing the risk of the motor 323 malfunctioning due to overheating or moisture, thus improving the safety of the equipment.

[0052] In one embodiment, the motor 323 and the lead screw 321 are connected by a reduction gear set 324.

[0053] The reduction gear set 324 can increase the torque output of the motor 323, enabling the lead screw 321 to withstand a greater load and ensuring the stable operation of the mounting rod 31 and nozzle 33 during the cleaning process, even under conditions of greater resistance.

[0054] In one embodiment, the lifting assembly 32 further includes a guide rod 325 arranged parallel to the lead screw 321, a guide sleeve 326 that can slide up and down is sleeved on the guide rod 325, and the end of the mounting rod 31 away from the nut 322 is fixedly connected to the guide sleeve 326.

[0055] The cooperation between the guide rod 325 and the guide sleeve 326 provides additional support and guidance for the mounting rod 31. The guide rod 325 can share some of the lateral force, so that the lead screw 321 mainly bears the axial force, thereby enhancing the load capacity of the entire lifting assembly 32, ensuring that the mounting rod 31 remains stable during the lifting process, and avoiding shaking or deviation caused by the rotation of the lead screw 321 or uneven load, thereby improving the stability of the cleaning process.

[0056] In one embodiment, reference is made to Figures 3-4 The bottom of the ventilation pipe 1 is provided with drainage holes 11 on the windward side and the leeward side of the filter screen 2, and each drainage hole 11 is provided with an upwardly protruding arc-shaped air guide plate 12 on the side near the air inlet of the ventilation pipe 1. The arc-shaped air guide plate 12 can prevent exhaust air from entering the drainage hole 11.

[0057] Drain holes 11 are provided on both sides of the filter screen 2, so that water on both sides can be discharged smoothly.

[0058] The design of the arc-shaped air guide plate 12 can guide the exhaust direction, allowing it to be discharged more smoothly through the ventilation pipe 1, reducing the direct impact of airflow on the drain hole 11, preventing exhaust air from flowing back into the drain hole 11, and avoiding noise.

[0059] In one embodiment, a drainage slope 13 is provided around the drainage hole 11, which can guide the accumulated water in the ventilation pipe 1 to converge into the drainage hole 11.

[0060] The drainage slope 13 can effectively guide the water in the ventilation pipe 1 to the drainage hole 11, so that the water can be discharged quickly, avoiding the accumulation in the ventilation pipe 1, reducing problems such as bacterial growth and odor caused by water accumulation, and maintaining the cleanliness and hygiene of the equipment.

[0061] On the other hand, a washer-dryer combo is provided, including the aforementioned filtration device.

[0062] Similarly, based on the filtration device provided in this embodiment, the washer-dryer combo of this embodiment maintains good air permeability of the filter screen 2 through timely and effective cleaning, avoiding abnormal machine operation caused by poor ventilation, reducing energy consumption, and thus extending the service life of the washer-dryer combo; and ensuring the smooth flow of the ventilation system helps to improve drying efficiency, shorten drying time, improve drying effect, and further enhance the user experience. Importantly, during the cleaning of the filter screen 2, the user does not need to manually disassemble the washer-dryer combo for cleaning, reducing the tediousness and technical requirements of manual operation, lowering maintenance costs and usage burden, and improving the user experience.
