Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a clothes dryer and its drying method. Background Technology

[0002] Currently, dryers are equipped with filters in their air ducts to capture lint generated during the drying process, preventing it from entering the heat pump system and the rear air duct, thus avoiding lint accumulation that could affect drying performance or cause safety hazards.

[0003] While the filter design effectively protects critical internal components, users need to manually clean the lint regularly, increasing the operational burden. This is especially true with frequent dryer use, where the cleaning frequency is high and may feel tedious. Furthermore, failure to clean the filter in a timely manner can lead to decreased filtration efficiency and even affect the normal operation of the dryer, further exacerbating user dissatisfaction. Summary of the Invention

[0004] Based on the above problems, the purpose of this invention is to provide a clothes dryer and its drying method that eliminates the need for traditional filters in the air duct, simplifies the daily maintenance of the equipment, alleviates user dissatisfaction, and improves the user experience.

[0005] To achieve the above objectives, the following technical solution is provided:

[0006] In a first aspect, the present invention provides a clothes dryer, comprising:

[0007] case;

[0008] A roller is rotatably disposed within the housing.

[0009] The first air duct is located on one side of the roller;

[0010] The second air duct is located on the other side of the roller;

[0011] A wire chip separation assembly includes a wire chip separation fan, a cyclone separator, and an exhaust pipe. The wire chip separation fan is disposed in the first air duct and provides a negative pressure environment to the first air duct so that the airflow from the second air duct enters the first air duct via the roller. The cyclone separator is connected to the first air duct, and the wire chips in the airflow of the first air duct can adhere to the side wall of the cyclone separator under the separation action of the cyclone separator. The exhaust pipe is disposed at the top of the cyclone separator.

[0012] As an optional embodiment of the dryer of the present invention, the dryer further includes a lint collection box, which is disposed at the bottom of the cyclone separator and is used to collect the lint separated by the cyclone separator.

[0013] As an optional embodiment of the dryer of the present invention, the inner wall of the cyclone separator is a conical wall. The lint in the airflow of the first air duct is thrown towards the conical wall under the action of centrifugal force and falls into the collection box along the conical wall.

[0014] As an optional embodiment of the dryer of the present invention, the conical wall is provided with an air inlet, and the airflow of the first air duct enters the cyclone separator through the air inlet.

[0015] As an optional embodiment of the dryer of the present invention, the housing is provided with a pick-up and drop-off port, and the lint collection box can pass through the pick-up and drop-off port.

[0016] As an optional embodiment of the dryer of the present invention, the housing is provided with a switch door, which is used to open or close the loading and unloading port.

[0017] As an optional embodiment of the dryer of the present invention, the switch door is rotatably disposed on the housing, or the switch door is slidably disposed on the housing.

[0018] As an optional embodiment of the dryer of the present invention, the door is provided with a handle.

[0019] As an optional embodiment of the dryer of the present invention, the housing is provided with a control panel, the control panel is provided with a fan speed setting button; and / or, the drum is provided with a humidity sensor.

[0020] As an optional embodiment of the dryer of the present invention, the drum is equipped with a humidity sensor.

[0021] Secondly, the present invention also provides a method for drying clothes in a dryer, wherein the clothes are dried using the aforementioned dryer, comprising the following steps:

[0022] S101, The wire chip separator provides a negative pressure environment for the first air duct so that the airflow of the second air duct enters the first air duct through the roller;

[0023] S102. The lint in the airflow of the first air duct adheres to the side wall of the cyclone separator under the separation action of the cyclone separator.

[0024] S103. Obtain the humidity data of the drum;

[0025] S104. Adjust the speed of the lint separator fan according to the humidity data of the drum.

[0026] The beneficial effects of this invention are as follows:

[0027] The dryer and drying method provided by this invention use a drum to hold the clothes to be dried. A lint-separating fan provides a negative pressure environment, driving airflow from a second air duct into the drum, and then through the drum into the first air duct, forming an airflow circulation. This ensures the flow of hot air during the drying process, thereby achieving uniform drying of the clothes. The lint-separating fan removes lint while driving the airflow of the entire machine, eliminating the need for a traditional fan to drive airflow circulation. During the drying process, lint from the clothes mixes with the airflow. The lint carried in the airflow of the first air duct enters the cyclone separator with the airflow, where it is further separated into lint and lint. Under the centrifugal force of the separator, lint is separated and adheres to the side wall of the cyclone separator, while clean airflow is discharged through the exhaust pipe at the top of the cyclone separator. This effectively prevents lint from entering the heat pump system and the rear air duct, preventing performance degradation or equipment failure caused by lint accumulation. The lint is automatically collected inside the cyclone separator, and users only need to clean the lint in the cyclone separator periodically, eliminating the need for traditional filters in the air duct. This greatly simplifies daily maintenance, especially for dryers used frequently, alleviating user dissatisfaction and improving the user experience. Furthermore, by acquiring the humidity data of the drum and dynamically adjusting the speed of the lint-separating fan, the dryer can optimize lint separation efficiency according to actual drying needs. This intelligent adjustment not only improves energy efficiency but also ensures the stability of lint separation under different humidity conditions. Attached Figure Description

[0038] like Figures 1 to 3As shown, this embodiment provides a clothes dryer, which includes a housing 1, a drum 2, a first air duct 3, a second air duct 4, and a lint separation assembly 5. The drum 2 is rotatably disposed inside the housing 1; the first air duct 3 is disposed on one side of the drum 2; the second air duct 4 is disposed on the other side of the drum 2; the lint separation assembly 5 includes a lint separating fan 51, a cyclone separator 52, and an exhaust pipe 53. The lint separating fan 51 is disposed in the first air duct 3 and is used to provide a negative pressure environment for the first air duct 3 so that the airflow from the second air duct 4 enters the first air duct 3 through the drum 2. The cyclone separator 52 is connected to the first air duct 3, and the lint in the airflow of the first air duct 3 can adhere to the side wall of the cyclone separator 52 under the separation action of the cyclone separator 52. The exhaust pipe 53 is disposed on the top of the cyclone separator 52.

[0039] The clothes to be dried are held in the drum 2, and a negative pressure environment is provided by the lint separator fan 51, which drives the airflow from the second air duct 4 into the drum 2, and then through the drum 2 into the first air duct 3, forming an airflow circulation. This ensures the flow of hot air during the drying process, thereby achieving uniform drying of the clothes. The lint separator fan 51 drives the airflow of the whole machine while removing lint, eliminating the need for a traditional fan to drive the airflow circulation. During the drying process, lint from the clothes is mixed into the airflow. The lint carried in the airflow of the first air duct 3 enters the cyclone separator 52 with the airflow, where it is centrifuged. Under the action of force, the lint is separated and adheres to the side wall of the cyclone separator 52, while the clean airflow is discharged through the exhaust pipe 53 at the top of the cyclone separator 52. This effectively prevents the lint from entering the heat pump system and the rear air duct, preventing performance degradation or equipment failure caused by lint accumulation. The lint is automatically collected in the cyclone separator 52, and users only need to clean the lint in the cyclone separator 52 periodically. There is no need to install traditional filters in the air duct, which greatly simplifies the daily maintenance of the equipment. Especially when the dryer is used frequently, it alleviates user dissatisfaction and improves the user experience.

[0040] To facilitate the collection of lint separated by the cyclone separator 52, the dryer optionally includes a lint collection box 6. The lint collection box 6 is located at the bottom of the cyclone separator 52 and is used to collect the lint separated by the cyclone separator 52. By placing the lint collection box 6 at the bottom of the lint separator 52, the separated lint can be automatically collected in the collection box. Users only need to clean the collection box periodically, without directly contacting the inside of the cyclone separator 52. This design further simplifies the lint cleaning process and improves user convenience. The design of the lint collection box 6 makes lint cleaning faster and more efficient, eliminating the need for users to spend a lot of time disassembling or cleaning complex parts, thereby reducing equipment downtime and ensuring the dryer can be put back into operation more quickly. The lint collection box 6 effectively collects and isolates lint, preventing it from scattering or re-entering the air duct system, avoiding secondary pollution problems caused by lint accumulation. This helps maintain the cleanliness of the equipment's interior, further improving drying efficiency and the stability of equipment operation. Because lint is collected centrally in the lint collection box 6, the amount of lint accumulated inside the cyclone separator 52 is significantly reduced, lowering the load on the cyclone separator 52, extending its service life, and reducing maintenance and replacement costs. The design of the lint collection box 6 makes cleaning cleaner and more convenient, eliminating the need for frequent contact with lint or disassembly of complex parts, reducing inconvenience and mess during cleaning, and thus improving user satisfaction with the dryer. By centrally collecting lint, the lint collection box 6 effectively prevents lint from re-entering the air duct or heat pump system, avoiding airflow obstruction or equipment malfunctions caused by lint blockage, further improving the reliability and safety of the equipment.

[0041] In some embodiments, the lint collection box 6 is made of a transparent or translucent material, allowing users to easily observe the accumulation of lint. Users can visually see the accumulation of lint and determine whether cleaning is necessary without opening the box. An anti-static coating is added to the inner wall of the lint collection box 6 to prevent lint from adhering to the box wall, facilitating cleaning.

[0042] Optionally, the inner wall of the cyclone separator 52 is a conical wall. Thread debris in the airflow of the first air duct 3 is thrown towards the conical wall by centrifugal force and falls into the collection box along the conical wall. The conical wall design of the cyclone separator 52 utilizes centrifugal force to efficiently throw thread debris in the airflow towards the wall, where it slides down to the thread debris collection box 6. This design significantly improves the efficiency of thread debris separation, ensuring that thread debris is quickly and thoroughly separated from the airflow, reducing thread debris residue. The conical wall structure allows the separated thread debris to slide smoothly down the wall into the collection box, preventing thread debris accumulation inside the cyclone separator 52 and reducing the risk of equipment performance degradation or malfunction due to thread debris accumulation. The conical wall design facilitates smooth airflow, reduces airflow resistance, and thus improves drying efficiency. Simultaneously, the separated thread debris does not interfere with the normal flow of airflow, further enhancing the operational stability of the equipment. Because lint automatically slides down the conical wall into the collection box, users only need to clean the collection box periodically, eliminating the need for complex cleaning of the inside of the cyclone separator 52. This design further simplifies the equipment maintenance process and enhances the user experience. The conical wall design reduces lint residue in the cyclone separator 52, lowering its load and extending its service life. Simultaneously, it prevents lint from entering the heat pump system or other critical components, reducing the likelihood of equipment failure. Through efficient separation and collection of lint, the conical wall design effectively prevents lint from clogging the air ducts or entering the heat pump system, ensuring long-term reliable operation of the equipment and reducing safety hazards caused by lint. Because the lint is efficiently separated and collected, the lint content in the airflow is significantly reduced, preventing lint from affecting the drying effect, thereby improving the drying quality and efficiency of clothing.

[0043] Optionally, an air inlet is provided on the conical wall, through which the airflow from the first air duct 3 enters the cyclone separator 52. By providing an air inlet on the conical wall, the airflow can enter the cyclone separator 52 in a more efficient manner, ensuring that the airflow forms a stable vortex within the separator, thereby improving the lint separation efficiency. This design makes the airflow distribution more uniform, avoiding the decrease in separation effect caused by airflow turbulence. The position and design of the air inlet allow the airflow to quickly form a vortex after entering the cyclone separator 52, enhancing the effect of centrifugal force, making it easier for lint to be thrown towards the conical wall, further improving the efficiency of lint separation. The reasonable design of the air inlet reduces the resistance when the airflow enters the cyclone separator 52, ensuring smooth airflow and avoiding the problem of decreased drying efficiency due to poor airflow. Because the airflow can quickly form a vortex after entering the cyclone separator 52 through the air inlet, the lint is efficiently thrown towards the conical wall under the action of centrifugal force and slides into the collection box, ensuring the complete separation and collection of lint and reducing lint residue. The air inlet is directly located on the conical wall, reducing additional pipes or connecting components, resulting in a more compact and simpler overall structure, and lowering manufacturing costs and maintenance difficulty. By optimizing the airflow entry method, the air inlet design ensures the stability of the airflow inside the cyclone separator 52, avoiding equipment instability caused by airflow turbulence and improving equipment reliability. Because the airflow can smoothly enter the cyclone separator 52 and efficiently separate lint, airflow resistance during the drying process is reduced, heat exchange efficiency is improved, thereby shortening drying time and increasing drying efficiency.

[0044] Optionally, the housing 1 is provided with an access port through which the lint collection box 6 can pass. By providing an access port on the housing 1, users can directly remove or insert the lint collection box 6 without disassembling the equipment casing or other components. This design significantly simplifies the lint cleaning process and improves user convenience. Users can quickly and intuitively remove and insert the lint collection box 6 through the access port without complex tools or operating skills, greatly shortening cleaning and maintenance time and increasing the flexibility of equipment use. The access port design avoids the risk of misoperation or component damage that may occur due to user disassembly, ensuring a safe and reliable maintenance process while protecting the integrity of the internal structure of the equipment. The position and size of the access port are ergonomically designed, allowing users to easily remove and insert the lint collection box 6, reducing inconvenience and mess during cleaning and improving user satisfaction. The access port design is seamlessly integrated with the structure of the housing 1, ensuring functionality while maintaining the dryer's clean and aesthetically pleasing appearance, avoiding the visual obtrusiveness caused by an external collection box or opening design. By directly accessing and placing the collection box, lint is less likely to scatter outside the equipment or into the air duct during cleaning, avoiding secondary pollution caused by flying lint during cleaning and ensuring the cleanliness of the equipment's interior and surrounding environment. The design of the access port makes the maintenance of the lint collection box 6 more modular. Even during equipment downtime or short pauses, users can quickly complete the cleaning, reducing equipment downtime and improving efficiency. This convenient cleaning method encourages users to handle lint more promptly, preventing the long-term impact of lint accumulation on critical components such as air ducts and heat pump systems, thereby extending the overall service life of the equipment.

[0045] Optionally, the housing 1 is provided with a switch door 7, which is used to open or close the loading / unloading port. By providing the switch door 7 to open or close the loading / unloading port, foreign objects can be effectively prevented from entering the equipment and the safety of the equipment during operation can be ensured. The design of the switch door 7 makes it more convenient and faster for users to replace the lint collection box 6, further improving the user experience.

[0046] In some embodiments, the switch door 7 is rotatably mounted on the housing 1, or the switch door 7 is slidably mounted on the housing 1. The switch door 7 can be mounted on the housing 1 by rotation or sliding, making the device design more flexible and adaptable to different installation and usage requirements. Both rotational and sliding designs ensure the stability and durability of the switch door 7, guaranteeing the reliability of the device during long-term use.

[0047] Optionally, the door 7 is equipped with a handle. By providing a handle to the door 7, it is easier and less strenuous for the user to open or close the access hatch, improving operational comfort. The handle design also makes operation more stable and safer, preventing accidents caused by improper operation.

[0048] The speed adjustment method of the wire shavings separator 51 includes manual adjustment. For example, in some embodiments, the housing 1 is equipped with a control panel, which has buttons for adjusting the fan speed. By setting the fan speed buttons on the control panel, users can adjust the speed of the wire shavings separator 51 according to actual needs, thereby optimizing the wire shavings separation effect. The fan speed setting design makes the equipment more intelligent and can meet the personalized needs of different users.

[0049] The speed adjustment method of the lint separator fan 51 includes automatic adjustment. For example, optionally, the drum 2 is equipped with a humidity sensor. By installing a humidity sensor on the drum 2, the humidity changes of the clothes can be monitored in real time, and the speed of the lint separator fan 51 can be adjusted according to the humidity data to optimize the lint separation effect. Of course, drying parameters can also be adjusted according to the humidity data to improve drying efficiency. The humidity sensor design can effectively prevent clothes from being over-dried, thereby protecting the quality and service life of the clothes. The humidity sensor installed in the drum 2 can monitor the humidity of the clothes in real time, thereby achieving more precise drying control, avoiding over-drying or under-drying, and improving drying effect and energy utilization efficiency.

[0050] The dryer provided in this embodiment, by introducing a lint separator 5, can automatically separate and collect lint generated during the drying process, eliminating the need for frequent manual cleaning of the filter. This significantly reduces the user's workload, especially when the dryer is used frequently, reducing cleaning frequency and improving the user experience. The lint separator 5 effectively captures and separates lint from the airflow, preventing it from entering the heat pump system and the rear air duct, thus avoiding decreased drying performance or equipment malfunction due to lint accumulation. This ensures the long-term stable operation of the dryer and reduces safety hazards caused by lint accumulation. The cyclone separator 52 is designed so that lint can efficiently adhere to its sidewalls, avoiding the problem of decreased filtration efficiency caused by clogging of traditional filters. This not only improves filtration efficiency but also extends the service life of the dryer and reduces the risk of equipment damage due to poor filtration. Since the lint separator 5 can automatically collect lint, the user only needs to clean the lint in the cyclone separator 52 periodically, making the maintenance process simpler. Compared to the frequent cleaning of traditional filters, this design greatly simplifies the daily maintenance of the equipment. The negative pressure environment provided by the lint separator fan 51 allows airflow to pass more smoothly through the drum 2 and the air duct, reducing airflow resistance caused by lint accumulation, thereby improving drying efficiency and shortening drying time.

[0051] like Figure 4 As shown, this embodiment also provides a method for drying clothes in a dryer, wherein the clothes are dried using the aforementioned dryer, including:

[0052] S101, the wire and lint separator fan 51 provides a negative pressure environment for the first air duct 3 so that the airflow of the second air duct 4 enters the first air duct 3 through the roller 2;

[0053] S102, the lint in the airflow of the first air duct 3 is attached to the side wall of the cyclone separator 52 under the separation action of the cyclone separator 52;

[0054] S103. Obtain the humidity data of roller 2;

[0055] S104. Adjust the speed of the lint separator fan 51 according to the humidity data of the roller 2.

[0056] The clothes to be dried are held in the drum 2, and a negative pressure environment is provided by the lint separator fan 51, which drives the airflow from the second air duct 4 into the drum 2, and then through the drum 2 into the first air duct 3, forming an airflow circulation. This ensures the flow of hot air during the drying process, thereby achieving uniform drying of the clothes. The lint separator fan 51 drives the airflow of the whole machine while removing lint, eliminating the need for a traditional fan to drive the airflow circulation. During the drying process, lint from the clothes is mixed into the airflow. The lint carried in the airflow of the first air duct 3 enters the cyclone separator 52 with the airflow, where it is centrifuged. Under the action of force, the lint is separated and adheres to the side wall of the cyclone separator 52, while the clean airflow is discharged through the exhaust pipe 53 at the top of the cyclone separator 52. This effectively prevents the lint from entering the heat pump system and the rear air duct, preventing performance degradation or equipment failure caused by lint accumulation. The lint is automatically collected in the cyclone separator 52, and users only need to clean the lint in the cyclone separator 52 periodically. There is no need to install traditional filters in the air duct, which greatly simplifies the daily maintenance of the equipment. Especially when the dryer is used frequently, it alleviates user dissatisfaction and improves the user experience.

[0057] By acquiring humidity data from the drum 2 and dynamically adjusting the speed of the lint-separating fan 51, the dryer can optimize lint separation efficiency according to actual drying needs. This intelligent adjustment not only improves energy efficiency but also ensures the stability of lint separation under different humidity conditions.

[0058] A humidity sensor is installed inside the drum to monitor the humidity of the clothing in real time. A controller processes the sensor data and executes control algorithms. A frequency converter or motor driver is used to adjust the speed of the lint separator fan 51. The lint separator fan 51 uses a speed-adjustable motor, supporting dynamic speed adjustment.

[0059] First, a humidity sensor collects real-time humidity data (e.g., humidity percentage or relative humidity value) inside the drum. The sensor sends the data to the controller. Second, the controller analyzes the current humidity state based on preset humidity thresholds or curves. For example: High humidity stage: humidity > 70% (early drying stage, clothes have high moisture content). Medium humidity stage: humidity 30%–70% (mid-drying stage, clothes are partially dry). Low humidity stage: humidity < 30% (late drying stage, clothes are nearly dry). Based on the humidity data analysis results, the controller dynamically adjusts the speed of the lint separator fan 51. Here is an example adjustment strategy: High humidity stage: Increase the fan speed to the highest setting (e.g., 1500 RPM) to enhance lint separation capability and airflow intensity. Medium humidity stage: Adjust the fan speed to the medium setting (e.g., 1000 RPM) to balance lint separation efficiency and energy consumption. Low humidity stage: Reduce the fan speed to the lowest setting (e.g., 500 RPM) to reduce energy consumption and avoid over-separation. Then, the controller sends control signals to the inverter or motor driver to adjust the input voltage or frequency of the fan motor, thereby regulating its speed. The fan adjusts its speed in real time according to the control signals. Finally, the system continuously monitors humidity data and fan speed, forming a closed-loop control. If humidity changes beyond the expected range (e.g., a sudden increase or decrease in the amount of laundry), the system automatically adjusts its speed strategy to adapt to the new drying conditions.

[0060] In some embodiments, the humidity range of the drum 2 and the rotational speed range of the lint separator fan 51 can have a one-to-one linear or non-linear relationship. Optionally, the detection range of the humidity sensor inside the dryer drum is set to (0—a, a—b, b—c, c—X), where X is the maximum value of the humidity sensing range. When the user puts clothes into the dryer and starts running, the humidity sensor begins to collect humidity data and feeds the data back to the drive board of the lint separator fan 51, converting it into a frequency signal to control the lint separator fan 51. This enables automatic adjustment of the rotational speed of the lint separator fan 51; the higher the humidity of the clothes inside the dryer drum, the higher the frequency of the variable frequency fan. For example, when the humidity range of the clothing being detected is 0 to a, the motor frequency is f1, where a can be 20% and f1 can be 35Hz; when the humidity range of the clothing being detected is a to b, the motor frequency is f2, where a can be 20%, b can be 40%, and f2 can be 40Hz; when the humidity range of the clothing being detected is b to c, the motor frequency is f3, where b can be 40%, c can be 60%, and f3 can be 45Hz; when the humidity range of the clothing being detected is c to X, the motor frequency is f4, where c can be 60%, X can be 80%, and f4 can be 50Hz.

[0061] During the drying process, the humidity data inside the drum changes in real time. When the humidity is high, the clothes contain more moisture, making it easier for lint to enter the air duct with the airflow; when the humidity is low, the amount of lint generated decreases. By monitoring the humidity inside the drum in real time through a humidity sensor, the system can dynamically adjust the speed of the lint-separating fan 51: increasing the speed to enhance lint separation capability when the humidity is high, and decreasing the speed to save energy when the humidity is low. This ensures that the lint separation efficiency remains at its optimal level under different humidity conditions, avoiding incomplete lint separation or energy waste caused by excessively high or low fan speeds.

[0062] In the later stages of drying, when clothes are nearly dry and the humidity is low, lint production decreases. At this time, the system automatically reduces the speed of the lint separator fan 51, reducing power consumption. This lowers the overall energy consumption of the dryer, aligning with energy-saving and environmentally friendly design principles. This also extends the fan's lifespan and reduces wear caused by prolonged high-speed operation.

[0063] In the initial drying stage, when the clothes are at a high moisture content, the system increases the fan speed to enhance the negative pressure within the air duct, accelerating airflow and thus improving drying efficiency. Simultaneously, the high-speed airflow helps to carry more lint into the cyclone separator 52 for separation. This speeds up the drying process and shortens the drying time. Ensuring unobstructed airflow prevents increased airflow resistance due to lint accumulation, thereby maintaining high-efficiency drying performance.

[0064] By dynamically adjusting the fan speed, the system can adjust the lint separation intensity according to actual needs, avoiding overheating or mechanical fatigue caused by continuous high-speed fan operation. This reduces equipment failure rate and improves the reliability of the dryer, minimizing safety hazards caused by fan overload or overheating. The system automatically adjusts the fan speed based on humidity data, requiring no manual intervention from the user; the entire process is fully automated. This enhances user convenience, reduces operational complexity, and increases user satisfaction with the dryer's intelligent functions.

[0065] By dynamically adjusting the fan speed, the system avoids prolonged high-speed operation of the fan, reducing wear on mechanical components. Simultaneously, efficient lint separation reduces the likelihood of lint entering the heat pump system and rear airflow, protecting critical components. This extends the overall lifespan of the dryer and reduces maintenance and repair costs.

[0066] Different garments have different materials, thicknesses, and moisture levels, resulting in varying amounts of lint during the drying process. The system dynamically adjusts the fan speed based on humidity data to adapt to the drying needs of different garments. This improves the dryer's versatility, meeting users' drying requirements for various garments and preventing poor drying results caused by insufficient or excessive lint separation.
