[0049] The working principle of the dryer is to generate hot air through the heating element, and then blow the hot air into the drum through the blower, so that the moisture in the clothes evaporates and is discharged outside the machine.

[0050] In the prior art, during the use of a clothes dryer, fibers and lint from clothes will fall off. If these shed fibers and lint are not handled properly, they may clog the ventilation system of the clothes dryer, reduce the drying efficiency, and even cause safety hazards such as fire. Therefore, clothes dryers are usually equipped with lint filters to capture and collect these shed fibers and lint.

[0051] At present, the lint filter is installed in the ventilation path of the dryer. The lint filter includes a filter frame and a filter screen, and the filter frame is arranged relative to each other to form a filter channel. In this way, when the air flow passes through the lint filter, fibers and lint are captured in the filter channel, while clean air continues to flow.

[0052] To keep your dryer running efficiently, the lint filter needs to be cleaned regularly. Users usually have to manually remove the lint filter, clean it of lint, and then reinstall it.

[0053] During the use of the lint filter, ideally, the lint accumulates at the bottom of the lint filter, so that the lint does not hinder the flow of air flow and improves the drying efficiency of the dryer. However, during the actual use of the lint filter, the lint may adhere to the filter net and the filter frame, causing the lint filter to be blocked and affecting the air flow of the dryer. For example, clothes made of certain materials (such as towels and wool products) are prone to dropping a large amount of fibers and lint during the drying process. These lint adheres to the filter net and the filter frame, which increases the burden on the lint filter.

[0054] During a drying cycle, the fallen lint gradually accumulates in the lint filter, which will clog the filter frame and filter screen of the lint filter. This will cause the circulating air volume to decrease and the drying efficiency to decrease. Even if multiple layers of filters are intercepted in sequence, clogging cannot be avoided.

[0055] Therefore, the lint filter of the existing clothes dryer has the problem of being clogged by lint.

[0056] In view of this, an embodiment of the present application provides a clothes dryer. The clothes dryer includes a body, a barrel, an air duct and a filter assembly. The body has a accommodating cavity. The barrel is located in the accommodating cavity. The barrel has a cavity with an opening at one end. The cavity is used to store clothes. The air duct is connected to the cavity. An airflow channel is formed between the air duct and the cavity. The filter assembly is arranged in the airflow channel. The filter assembly has a filter channel. Along the extension direction of the filter channel, at least one reduced diameter section is arranged on the filter channel. The inner diameter of the channel of the reduced diameter section is smaller than the inner diameter of the channel at other positions of the filter channel. In the present application, at least one reduced diameter section is arranged on the filter channel, and the channel diameter of the reduced diameter section is smaller than the channel diameter at other positions of the filter channel. In this way, the flow rate of the airflow in the reduced diameter section becomes larger, and the airflow blows off the wire scraps adhering to the filter assembly, avoiding the clogging of the wire scraps on the filter assembly, thereby improving the performance of the dryer.

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] Figure 1 The structure of the clothes dryer provided in the embodiment of the present application is schematically shown. Figure 1 . Figure 2 The structure of the clothes dryer provided in the embodiment of the present application is schematically shown. Figure 2 . Figure 3 The filter assembly 300 provided in an embodiment of the present application is schematically shown.

[0065] Reference Figures 1 to 3 As shown, the present application provides a clothes dryer, including a body, a barrel 100, an air duct 200 and a filter assembly 300. The body has a receiving cavity. The barrel 100 is located in the receiving cavity. The barrel 100 has a cavity with an open end. The cavity is used to store clothes. The air duct 200 is connected to the cavity. An air flow channel is formed between the air duct 200 and the cavity. The filter assembly 300 is arranged in the air flow channel.

[0066] The filter assembly 300 has a filter channel 340. Along the extension direction of the filter channel 340, at least one diameter-reducing section is provided on the filter channel 340. The inner diameter of the channel of the diameter-reducing section is smaller than the inner diameter of the channel at other positions of the filter channel 340.

[0067] For example, refer to Figure 1 As shown, the dryer also includes a front support 400, a base upper shell 500, a base lower shell 600, a heat pump system, a circulating fan, a drum rotating motor, an auxiliary heating module, and a rear cover 700. During the use of the dryer, the circulating fan drives the hot air in the barrel through the front support 400 and the filter channel 340 of the filter assembly 300 to enter the air duct 200 formed by the base upper shell 500 and the base lower shell 600, and the heat pump system is installed in the air duct 200 to achieve condensation and heating of the humid hot air. The heated hot air enters the cavity. During the drying process, the lint on the clothes will enter the air flow channel with the circulating air. The humid hot air mixed with lint first passes through the filter assembly 300 to prevent the lint from contaminating the evaporator and condenser, thereby reducing the drying efficiency. Refer to the flow direction of the airflow. Figure 1 Indicated by the solid black arrow.

[0068] For example, when the airflow in the clothes dryer flows to the filter assembly 300, since the filter channel 340 of the filter assembly 300 is provided with a reduced diameter section, the ventilation area of ​​the filter assembly 300 is reduced, the airflow velocity flowing through the reduced diameter section becomes larger, and the accelerated airflow impacts the wire scraps adhering to the inner wall of the filter channel 340. Under the action of the airflow, the wire scraps are blown to the designated position of the filter assembly 300. By providing the reduced diameter section on the filter channel 340, the reduced diameter section can improve the flow of the airflow, prevent the wire scraps from adhering to the filter assembly 300, and prevent the filter assembly 300 from being blocked. At the same time, by improving the flow velocity of the airflow, the airflow blows the wire scraps to the designated position, which is convenient for the user to centrally handle the wire scraps later.

[0069] Exemplarily, the circulation fan is controlled to rotate and the speed of the drum rotation motor is increased so that the clothes abut against the inner wall of the drum 100, thereby increasing the ventilation area of ​​the cavity, increasing the ventilation volume in the cavity, and thereby increasing the air flow velocity in the filter channel 340, and also avoiding the blockage of lint in the filter assembly 300.

[0070] Figure 4 The structural diagram of the external filter component 300a provided in an embodiment of the present application is schematically shown. Figure 5 The structural diagram of the internal filter component 300b provided in the embodiment of the present application is schematically shown.

[0071] As a feasible implementation method, refer to Figure 4 and Figure 5 As shown, the filter assembly 300 includes an outer filter assembly 300a and an inner filter assembly 300b.

[0072] The external filter assembly 300a includes a plurality of external connection segments 310. The plurality of external connection segments 310 are sequentially arranged at intervals and surround to form an external filter channel 340, and the internal filter assembly 300b is located in the external filter channel 340.

[0073] The internal filter assembly 300 b includes a plurality of internal connection segments 310 , and the plurality of internal connection segments 310 are disposed in one-to-one correspondence with the plurality of external connection segments 310 .

[0074] For example, during the operation of the clothes dryer, the internal filter assembly 300b first captures larger lint and particles, playing a role of preliminary filtration. The external filter assembly 300a further captures smaller lint and particles, providing a more refined filtration effect. The double-layer filtration design can significantly improve the overall filtration efficiency of the clothes dryer.

[0075] By providing the internal filter assembly 300b and the external filter assembly 300a, double-layer filtration of the dryer lint is achieved, which helps to collect the lint and prevents the lint from entering the air duct 200 of the dryer and affecting the working efficiency of the dryer. In addition, the combined design of the external filter assembly 300a and the internal filter assembly 300b can increase the overall strength and stability of the filter assembly 300, avoid deformation under high flow rate and high temperature environment, and increase the service life of the filter assembly 300.

[0076] As an achievable implementation, the filter assembly 300 includes a plurality of connecting segments 310. The plurality of connecting segments 310 are sequentially arranged at intervals and surround to form a filter channel 340.

[0077] The connection section 310 is provided with a filter structure 320. Along the height direction of the clothes dryer, the middle portion of the filter structure 320 bulges outwards toward the filter channel 340 relative to both ends of the filter structure 320 to form a reduced diameter section.

[0078] Illustratively, the reduced diameter section formed by the outward protrusion in the middle of the filter structure 320 can increase the air flow rate. Under the action of the airflow, the lint accumulated near the filter structure 320 is blown to the designated position of the filter assembly 300, thereby avoiding the accumulation of lint in the filter channel 340 and reducing the clogging problem of the filter channel 340.

[0079] For example, the combined design of the plurality of connecting segments 310 can increase the overall strength and stability of the filter assembly 300 and avoid deformation in a high flow rate and high temperature environment.

[0080] Figure 6 The structure of the filter assembly 300 of the clothes dryer provided in the embodiment of the present application is schematically shown. Figure 1 . Figure 7 for Figure 6 Schematic diagram of the structure of area A in the middle. Figure 8 for Figure 6 Schematic diagram of the structure of area B.

[0081] As an achievable implementation, the filter assembly 300 further includes a filter screen. The filter screen is provided with through holes. Two adjacent connecting sections 310 are connected by the filter screen. The filter screen is used to capture finer wire scraps and fiber particles, further improving the filtering effect.

[0082] For example, refer to Figures 6 to 8As shown, during the use of the clothes dryer, the airflow through the drum 100 first flows to the first end of the filter channel 340. When the airflow flows to the filter structure 320, since the middle of the filter structure 320 bulges outward in the direction close to the filter channel 340 relative to the two ends of the filter structure 320, the filter structure 320 causes the cross-sectional area of ​​the filter channel 340 to become smaller, that is, the flow rate will increase when the airflow flows to the reduced diameter section of the filter channel 340. If there are wire scraps accumulated in the filter structure 320 and its vicinity at this time, the airflow with increased speed impacts the wire scraps and applies external force to the wire scraps. At this time, the wire scraps move to the second end of the filter channel 340 under the action of their own gravity and the impact force applied by the airflow. In this way, by setting the filter structure 320, a reduced diameter section is formed on the filter channel 340 to prevent the accumulation of wire scraps near the reduced diameter section.

[0083] Exemplarily, the filter screen and the filter structure 320 can be tightly connected, that is, at least part of the filter screen protrudes outward toward the filter channel 340 relative to other parts of the filter screen. In this way, the ventilation area of ​​the filter screen can be effectively increased, and the ventilation volume can be reduced less when the same amount of wire scraps is intercepted.

[0084] Exemplarily, the filtering structure 320 and the connecting section 310 may be formed integrally.

[0085] For example, the convex middle portion design of the filter structure 320 can increase the overall strength and stability of the filter assembly 300 and avoid deformation in high air flow velocity and high temperature environments.

[0086] As an achievable implementation, the filter assembly 300 further includes an air inlet plate 330. The air inlet plate 330 is provided with a plurality of air inlet holes. The air inlet plate 330 is disposed at a first end of the filter channel 340. The first end of the filter channel 340 is close to the top of the dryer. The air inlet plate 330 is connected to the connecting section 310.

[0087] For example, the multiple air inlet holes on the air inlet plate 330 can allow air to enter the filter channel 340 evenly, avoiding excessive or weak airflow in the filter channel 340, thereby optimizing the flow of air in the filter channel 340 and the air duct 200. At the same time, the air inlet holes on the air inlet plate 330 can play a role of pre-filtering, capturing larger particles of wire scraps, reducing the amount of wire scraps entering the filter channel 340, thereby improving the overall filtering efficiency.

[0088] The combined design of the air inlet plate 330 and the connecting section 310 can increase the overall strength and stability of the filter assembly 300 and prevent the filter assembly 300 from being deformed under high air flow velocity and high temperature environments.

[0089] As an achievable implementation, the first end of the connecting section 310 is connected to the air inlet plate 330. The second end of the connecting section 310 is connected via a connecting rod.

[0090] Along the height direction of the dryer, the cross-sectional area of ​​the filter channel 340 near the top of the dryer is larger than the cross-sectional area of ​​the filter channel 340 near the bottom of the dryer. The cross-sectional area of ​​the filter channel 340 gradually decreases from the top to the bottom. This design can make the air flow smoother and reduce the generation of turbulence and eddy currents. At the same time, as the cross-sectional area of ​​the filter channel 340 decreases, the air flow speed will gradually increase, which helps to improve the efficiency of capturing lint. In this way, it helps the filter assembly 300 to collect all the lint at the bottom of the filter channel 340, making it easier for users to clean up the lint.

[0091] As a feasible implementation, the filter structure 320 includes a filter section. Both ends of the filter section are connected to the connecting section 310 respectively. The middle of the filter section bulges outwards toward the filter channel 340 relative to the two ends of the filter section. The reduced diameter section formed by the bulge in the middle of the filter section can increase the airflow velocity, so that the accelerated airflow will bring the wire scraps adhering to the filter net and the connecting section 310 to the bottom of the filter channel 340, realize the centralized management of the wire scraps, and facilitate the user to clean the wire scraps. At the same time, since the wire scraps are no longer adhered to the filter net and the connecting section 310, the airflow can smoothly flow through the filter channel 340 to the air duct 200, thereby improving the drying efficiency of the clothes dryer.

[0092] As a feasible implementation, along the length direction of the dryer, the shape of the filter structure 320 includes an arc shape and a sharp angle shape.

[0093] In some embodiments, the shape of the filter section along the length direction of the clothes dryer includes an arc shape. The arc-shaped filter structure 320 can provide a smooth airflow path, reduce airflow resistance and turbulence, and further improve the filtering efficiency. At the same time, the surface of the arc structure is relatively smooth, which reduces the possibility of lint adhering to the filter structure 320, and avoids the accumulation of lint from hindering the flow of airflow.

[0094] In other embodiments, the shape of the filter section along the length direction of the clothes dryer includes a sharp angle. Filter structures 320 of different shapes can provide diverse filtering effects, adapt to different types and sizes of lint, and improve the filtering efficiency of the clothes dryer.

[0095] As an achievable implementation, the filter segment includes a first filter segment 321 and a second filter segment 322. The first end of the first filter segment 321 is connected to the first end of the connecting segment 310. The first end of the second filter segment 322 is connected to the second end of the connecting segment 310. The second end of the first filter segment 321 is connected to the second end of the second filter segment 322.

[0096] The second end of the first filter segment 321 is closer to the filter channel 340 relative to the first end of the first filter segment 321 . The second end of the second filter segment 322 is closer to the filter channel 340 relative to the first end of the second filter segment 322 .

[0097] As shown in FIG6 , the arrangement of the first filter segment 321 and the second filter segment 322 makes the filter structure 320 present a sharp angle shape.

[0098] For example, refer to Figure 7 As shown, when the first filter segment 321 accumulates wire scraps, after the airflow flows from the cavity to the first end of the filter channel 340, the airflow blows the wire scraps and applies an impact force to the wire scraps. In this way, the wire scraps slide down from the first end of the first filter segment 321 to the second end of the first filter segment 321 under the impact force of the airflow and its own gravity. The sliding direction of the wire scraps is shown in FIG. Figure 7 The direction is indicated by the solid black arrow.

[0099] For example, refer to Figure 8 As shown, when the second filter segment 322 accumulates wire scraps, after the airflow flows from the cavity to the first end of the filter channel 340, the airflow blows the wire scraps and applies an impact force to the wire scraps. In this way, the wire scraps slide down from the second end to the first end of the second filter segment 322 under the impact force of the airflow and its own gravity. Figure 8 The hollow arrow indicates the direction.

[0100] Exemplarily, the combined design of the first filter segment 321 and the second filter segment 322 can increase the overall strength and stability of the filter assembly 300 and prevent the filter assembly 300 from deforming under high air flow velocity and high temperature environments.

[0102] As an achievable implementation, there are multiple filter structures 320. Along the extension direction of the connecting section 310, multiple filter structures 320 are sequentially arranged on the connecting section 310.

[0103] In some embodiments, reference Fig. 9 As shown, the number of the filtering structure 320 is one, and one filtering structure 320 is disposed at the end of the connecting section 310 close to the air inlet plate 330 .

[0104] In some other embodiments, reference Fig.10 As shown, there are multiple filtering structures 320 , some of which are disposed near the first end of the connecting section 310 , and some of which are disposed near the second end of the connecting section 310 .

[0105] In other embodiments, referring to Figure 6 and Fig.11 As shown, there are multiple filtering structures 320 , and the multiple filtering structures 320 are sequentially spaced from the first end of the connecting section 310 to the second end of the connecting section 310 .

[0106] By adjusting the number and intervals of the filtering structures 320 , the length and filtering effect of the filtering channel 340 can be flexibly changed to meet different usage requirements.

[0107] As a feasible implementation, the angle between the extension direction from the first end of the first filter segment 321 to the second end of the first filter segment 321 and the extension direction of the connecting segment 310 is greater than 0° and less than 90°; to ensure that the first filter segment 321 is inclined.

[0108] By setting the first filter segment 321 and the second filter segment 322 to be inclined, it helps to reduce the resistance of gas flow, promote the smooth passage of airflow through the filter structure 320, and ensure the smooth drying process of the clothes dryer.

[0109] Exemplarily, when the angle between the extension direction from the first end of the first filter segment 321 to the second end of the first filter segment 321 and the extension direction of the connecting segment 310 is greater than or equal to 90°, the lint will accumulate on the first filter segment 321, causing lint blockage, which is not conducive to the flow of airflow, reduces the smoothness of the airflow of the clothes dryer, and reduces the drying effect of the clothes dryer. Therefore, in the embodiment of the present application, the angle between the extension direction from the first end of the first filter segment 321 to the second end of the first filter segment 321 and the extension direction of the connecting segment 310 is set to be greater than 0° and less than 90° to avoid the accumulation of lint on the first filter segment 321.

[0110] The embodiment of the present application provides a clothes dryer, comprising a machine body, a drum 100, an air duct 200 and a filter assembly 300. The drum 100 is located in a receiving cavity of the machine body, and the drum 100 has a cavity with one end open. The cavity is used to store clothes.

[0111] The air duct 200 is used to communicate with the cavity. An air flow channel is formed between the air duct 200 and the cavity. The filter assembly 300 is arranged in the air flow channel. The filter assembly 300 is used to filter the wire scraps in the air flow channel.

[0112] The filter assembly 300 has a filter channel 340. Along the extension direction of the filter channel 340, at least one diameter-reducing section is provided on the filter channel 340. The inner diameter of the channel of the diameter-reducing section is smaller than the inner diameter of the channel at other positions of the filter channel 340.

[0113] In the clothes dryer provided by the embodiment of the present application, when the airflow in the clothes dryer flows to the filter assembly 300, since the filter channel 340 of the filter assembly 300 is provided with a reduced diameter section, the ventilation area of ​​the filter channel 340 is reduced, the airflow velocity flowing through the reduced diameter section becomes larger, and the accelerated airflow impacts the wire scraps adhering to the inner wall of the filter channel 340. Under the action of the airflow, the wire scraps are blown to the designated position of the filter assembly 300. By providing the reduced diameter section on the filter channel 340, the reduced diameter section can improve the flow of the airflow, prevent the wire scraps from adhering to the filter assembly 300, and prevent the filter assembly 300 from being blocked. At the same time, by improving the flow velocity of the airflow, the airflow blows the wire scraps to the designated position, which is convenient for users to centrally handle the wire scraps later, and improves the use performance of the wire scraps.
