Description

Technical Field

[0001] This application relates to the field of washing equipment technology, and more particularly to a clothes dryer. Background Technology

[0002] As people's pace of life accelerates, the demand for laundry and drying equipment is increasing, with particular attention paid to the drying effect and efficiency of these machines.

[0003] Currently, washing and drying equipment such as dryers have a built-in rotating drying drum. When working, a fan generates hot air and blows the hot air into the inside of the drying drum from the bottom. As the clothes rotate inside the drying drum, the hot air dries the moisture on the surface of the clothes, achieving the drying effect.

[0004] However, most clothes dryers on the market are inefficient and energy-intensive when drying small amounts of clothes. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the related technologies, this application provides a clothes dryer to solve the problems of poor drying efficiency and high energy consumption when drying a small amount of clothes.

[0006] To address the aforementioned technical problems, in a first aspect, this application provides a clothes dryer, which includes:

[0007] main body;

[0008] The inner drum is rotatably disposed inside the main body, and the interior of the inner drum forms a drying chamber for drying clothes.

[0009] The drying air duct is located outside the inner cylinder and is used to generate hot air for drying. The drying air duct has an air outlet facing the inner cylinder.

[0010] A blower is installed in the drying duct to blow hot air from the drying duct to the air outlet.

[0011] The inner cylinder includes:

[0012] The base plate and the air outlet are positioned opposite each other.

[0013] The cylinder sidewall is wrapped around the edge of the bottom plate, and the bottom plate and the cylinder sidewall together form a drying chamber.

[0014] Lifting ribs are installed on the side wall of the cylinder and located inside the drying chamber;

[0015] The base plate is provided with a connecting port and multiple first air outlets. The first air outlets and the connecting port both penetrate through the opposite sides of the base plate. The first air outlets are configured to blow hot air from the drying air duct into the drying chamber through the first air outlets. The positions of the connecting port and the lifting ribs are corresponding and opposite to each other, and the cross-sectional area of ​​the connecting port is larger than the cross-sectional area of ​​a single first air outlet.

[0016] The internal structure of the lifting rib is a connecting cavity with an opening; the opening and the connecting port are opposite to and connected to each other, and the connecting cavity is configured to blow hot air in the drying air duct into the connecting cavity in sequence through the connecting port and the opening; a second air outlet is provided on the side of the lifting rib facing the inside of the drying cavity, the second air outlet is connected to the connecting cavity, and the second air outlet is configured to blow hot air in the connecting cavity into the drying cavity through the second air outlet.

[0017] With this design, during the drying process, the lifting ribs can rotate with the inner drum to lift the clothes along the height of the dryer. This allows the clothes to be released after being raised to a certain height, increasing the contact area between the clothes and the hot air, thus avoiding heat waste and improving the drying efficiency and effect of the dryer.

[0018] Furthermore, hot air can be blown into the clothes inside the drying chamber through the first air outlet and the second air outlet respectively. The hot air entering the drying drum from the first air outlet and the hot air entering the drying drum from the second air outlet can dry the clothes from different directions, which improves the drying efficiency and drying effect of the dryer.

[0019] The connecting opening and the lifting ribs are positioned correspondingly and relative to each other, reducing the impact of their placement on the first air outlet. This allows the connecting opening and lifting ribs to be installed without reducing or minimizing the number of first air outlets, thus ensuring the dryer's drying efficiency. The cross-sectional area of ​​the connecting opening is larger than that of a single first air outlet, allowing more hot air to enter the connecting cavity and then through the second air outlet into the drying cavity. This increases the airflow from the second air outlet, thereby improving the dryer's drying efficiency and effect.

[0020] Optionally, the base plate has multiple connecting ports, and the connecting ports and lifting ribs are provided in a one-to-one correspondence, and the geometric centers of the connecting ports and the base plate are spaced apart in the radial direction of the base plate.

[0021] This design helps prevent small amounts of clothing from accumulating at the bottom of the drum side wall and increases the number of second air outlets, thereby improving the drying efficiency and effect of the dryer.

[0022] Optionally, the lifting ribs include:

[0023] The lifting rib body extends along the side wall of the cylinder, and the second air outlet and at least part of the connecting cavity are both provided in the lifting rib body.

[0024] This design allows the lifting ribs to rotate with the inner drum during the drying process, lifting the clothes along the dryer's height. This prevents clothes from piling up and ensures that hot air from the higher first air outlet reaches the clothes, avoiding heat waste and improving the dryer's efficiency and drying effect. Furthermore, hot air can also be blown onto the clothes inside the drying chamber through the second air outlet. The hot air entering the drying drum from the second and first air outlets can dry the clothes from different directions, further enhancing the dryer's efficiency and drying effect.

[0025] Optionally, the lifting rib also includes:

[0026] The connecting part is connected to the side of the lifting rib body facing the bottom plate, and the connecting part is connected to the bottom plate, and the connecting part covers the outside of the connecting opening;

[0027] The opening is located at the connecting part, and the connecting cavity extends from the connecting part to the main body of the lifting rib.

[0028] With this configuration, the connecting port and the connecting part are positioned opposite each other, so that the cross-sectional area of ​​the connecting port is not limited by the size of the lifting rib body. This allows for an increase in the area of ​​the connecting port, enabling more hot air to enter the connecting cavity from the connecting port and be blown into the drying cavity through the second air outlet, thereby improving the drying efficiency and drying effect of the dryer.

[0029] Optionally, the connecting part extends through the communication opening, and the bottom end of the connecting part extends to the side of the base plate away from the drying chamber, with the opening located at the bottom end of the connecting part.

[0030] This design facilitates the installation of the lifting ribs on the base plate and allows hot air from the drying duct to enter the connecting cavity through the opening. Furthermore, it reduces the volume of the connecting part protruding from the base plate, resulting in a flatter base plate, minimizing the impact of the connecting part on the clothes inside the drying drum, and improving the visual appeal of the dryer.

[0031] Optionally, the main body of the lifting rib has a first external appearance surface, and the connecting part has a second external appearance surface;

[0032] The appearance of the first exterior surface matches the appearance of the cylinder sidewall, and the appearance of the second exterior surface matches the appearance of the bottom plate.

[0033] This setting helps to improve the visual appeal of the dryer.

[0034] Secondly, this application also provides another type of dryer, which includes:

[0035] include:

[0036] main body;

[0037] The inner drum is rotatably disposed inside the main body, and the interior of the inner drum forms a drying chamber for drying clothes.

[0038] The drying air duct is located outside the inner cylinder and is used to generate hot air for drying. The drying air duct has an air outlet facing the inner cylinder.

[0039] A blower is installed in the drying duct to blow hot air from the drying duct to the air outlet.

[0040] The inner cylinder includes:

[0041] The base plate and the air outlet are positioned opposite each other.

[0042] The cylinder sidewall is wrapped around the edge of the bottom plate, and the bottom plate and the cylinder sidewall together form a drying chamber.

[0043] Lifting ribs are installed on the side wall of the cylinder and located inside the drying chamber;

[0044] The air duct component is located on the side of the base plate away from the drying chamber and between the base plate and the air outlet. The air duct component has a first air duct and a second air duct, and the first air duct and the air outlet are opposite to and connected to each other.

[0045] The base plate is provided with a connecting port and multiple first air outlets. The first air outlets and the connecting port both penetrate through the opposite sides of the base plate. The first air duct and the first air outlet are arranged opposite each other and are configured to blow hot air in the drying air duct into the drying chamber through the first air outlet. The second air duct connects the first air duct and the connecting port. The second air duct is configured to blow hot air in the first air duct into the connecting port. The positions of the connecting port and the lifting ribs are corresponding and arranged opposite each other, and the cross-sectional area of ​​the connecting port is larger than the cross-sectional area of ​​a single first air outlet.

[0046] The internal structure of the lifting rib is a connecting cavity with an opening; the opening and the connecting port are opposite to and connected to each other, and the connecting cavity is configured to blow hot air in the drying air duct into the connecting cavity in sequence through the connecting port and the opening; a second air outlet is provided on the side of the lifting rib facing the inside of the drying cavity, the second air outlet is connected to the connecting cavity, and the second air outlet is configured to blow hot air in the connecting cavity into the drying cavity through the second air outlet.

[0047] With this design, during the drying process, the lifting ribs can rotate with the inner drum to lift the clothes along the height of the dryer. This allows the clothes to be released after being raised to a certain height, increasing the contact area between the clothes and the hot air, thus avoiding heat waste and improving the drying efficiency and effect of the dryer.

[0048] Furthermore, hot air can be blown into the clothes inside the drying chamber through the first air outlet and the second air outlet respectively. The hot air entering the drying drum from the first air outlet and the hot air entering the drying drum from the second air outlet can dry the clothes from different directions, which improves the drying efficiency and drying effect of the dryer.

[0049] The connecting opening and the lifting ribs are positioned correspondingly and relative to each other, reducing the impact of their placement on the first air outlet. This allows the connecting opening and lifting ribs to be installed without reducing or minimizing the number of first air outlets, thus ensuring the dryer's drying efficiency. The cross-sectional area of ​​the connecting opening is larger than that of a single first air outlet, allowing more hot air to enter the connecting cavity and then through the second air outlet into the drying cavity. This increases the airflow from the second air outlet, thereby improving the dryer's drying efficiency and effect.

[0050] On the other hand, the second air duct can be used to guide hot air from the first air duct into the connecting port, so that the connecting port does not need to be directly connected to the air outlet of the drying air duct, allowing for more flexible placement of the connecting port. For example, the connecting port may not face the opening and may be spaced apart from the opening.

[0051] Optionally, the first air duct runs through the two ends of the air duct component, the first end of the second air duct is connected to the first air duct, and the second end of the second air duct is configured to be opposite to and connected to the connecting port;

[0052] In the radial direction of the base plate, the connecting port is closer to the cylinder sidewall than the first end of the second air duct.

[0053] Therefore, the second air duct is used to guide the hot air in the first air duct to flow radially towards the side wall of the cylinder along the bottom plate. The connecting port can be set at the position of the bottom plate near the side wall of the cylinder without the first air outlet, so as to reduce the impact of setting the connecting port on the first air outlet. The connecting port can be opened without reducing or minimizing the reduction of the first air outlet, which is conducive to ensuring the drying efficiency and drying effect of the dryer.

[0054] Optionally, the air duct components include:

[0055] The main body of the air duct is ring-shaped, and the two opposite ends of the main body of the air duct are respectively connected to the bottom plate and the drying air duct to form the first air duct. The main body of the air duct has a gap that communicates with the first air duct.

[0056] An air guide is disposed at the gap and forms at least part of the wall of the second air duct, the second air duct and the gap being connected.

[0057] With this configuration, the air guide can guide the hot air in the first air duct into the connecting port through the second air duct. The connecting port does not need to be directly connected to the air outlet of the drying air duct, so that the location of the connecting port can be set more flexibly.

[0058] Optionally, the drying air duct includes:

[0059] The flexible seal surrounds the air outlet, and the flexible seal is in close contact with the air duct component;

[0060] The flexible seal has a sound-absorbing and noise-reducing material on the side surface that contacts the air duct component; or the flexible seal is made of sound-absorbing and noise-reducing material.

[0061] This design allows the sound-absorbing and noise-reducing material to reduce the noise generated by friction between the air duct components and the flexible seals when the inner cylinder rotates, thus improving the user experience. Attached Figure Description

[0079] As mentioned in the background section, with the accelerating pace of life, the demand for laundry and drying equipment is increasing, especially regarding the drying effect and efficiency. Currently, laundry and drying equipment such as dryers have a built-in rotating drying drum. During operation, a fan generates hot air, which is blown into the drum from the bottom. As the clothes rotate inside the drum, the hot air dries the surface moisture, achieving the desired drying effect. However, most dryers on the market currently have poor drying efficiency and consume a lot of energy when drying small amounts of clothing.

[0080] To address the aforementioned problems, this application provides a clothes dryer that solves the issues of poor drying efficiency and high energy consumption in related technologies when drying small quantities of clothing.

[0081] Please refer to Figures 1 to 3 The dryer 10 of this application includes: a main body, an inner drum 100, a drying duct 200, and a fan 300. The inner drum 100 has a drying chamber 110 for drying clothes. The drying duct 200 is located outside the inner drum 100 and has an air outlet 210 facing the inner drum 100 and communicating with the drying chamber 110. Hot air for drying is generated within the drying duct 200. The fan 300 is located within the drying duct 200 and blows the hot air from the drying duct 200 to the air outlet 210. Thus, the hot air within the drying duct 200 can enter the drying chamber 110 from the air outlet 210 to dry the clothes. The inner drum 100 can rotate within the main body, thereby tumbling the clothes during the drying process, preventing clothes from piling up, and improving drying efficiency.

[0082] The inner cylinder 100 includes a bottom plate 120 and a cylinder side wall 130 surrounding the edge of the bottom plate 120. The bottom plate 120 and the cylinder side wall 130 together form a drying chamber 110. The bottom plate 120 and the air outlet 210 are arranged opposite to each other, and a plurality of first air outlet holes 121 are provided through the opposite sides of the bottom plate 120. The first air outlet holes 121 communicate with the air outlet 210 and are used to blow hot air in the drying air duct 200 into the drying chamber 110 through the first air outlet holes 121 to dry clothes.

[0083] The inner drum 100 also includes lifting ribs 140, which are located on the side wall 130 of the drum and within the drying chamber 110. Therefore, during the drying process, the lifting ribs 140 can rotate with the inner drum 100 to lift the clothes along the height of the dryer 10, allowing them to be released after being raised to a certain height, thereby increasing the contact area between the clothes and the hot air. This design avoids heat waste and improves the drying efficiency and effect of the dryer 10.

[0084] The internal structure of the lifting rib 140 is a connecting cavity 141 with an opening 142. The base plate 120 is provided with connecting ports 122 penetrating both sides of the base plate 120. The connecting ports 122 are opposite to and communicate with the openings 142. The connecting ports 122 also communicate with the air outlet 210. Thus, the connecting ports 122 connect the drying air duct 200 and the connecting cavity 141. The connecting cavity 141 can be used to blow hot air from the drying air duct 200 into the connecting cavity 141 through the connecting ports 122 and the openings 142 in sequence.

[0085] The lifting rib 140 has a second air outlet 143 on one side surface facing the inside of the drying chamber 110, which is connected to the connecting chamber 141. The second air outlet 143 is used to blow hot air from the connecting chamber 141 into the drying chamber 110 through the second air outlet 143.

[0086] With this configuration, hot air can be blown into the clothes in the drying chamber 110 through the first air outlet 121 and the second air outlet 143 respectively. The hot air entering the drying drum from the first air outlet 121 and the hot air entering the drying drum from the second air outlet 143 can dry the clothes from different directions, thereby improving the drying efficiency and drying effect of the dryer 10.

[0087] The positions of the connecting port 122 and the lifting rib 140 are corresponding and relatively arranged, which reduces the impact of the connecting port 122 and the lifting rib 140 on the first air outlet 121. This allows the connecting port 122 and the lifting rib 140 to be set without reducing or minimizing the reduction of the first air outlet 121, which is beneficial to ensuring the drying efficiency of the dryer 10. The cross-sectional area of ​​the connecting port 122 is larger than the cross-sectional area of ​​a single first air outlet 121, thereby allowing more hot air to enter the connecting cavity 141 and enter the drying cavity 110 through the second air outlet 143, increasing the air volume of the second air outlet 143, and improving the drying efficiency and drying effect of the dryer 10.

[0088] The clothes dryer 10 provided in this application embodiment can be used not only for drying clothes, but also for drying towels, sheets, quilts and other fabrics. The following embodiment will take drying clothes with the clothes dryer 10 as an example. Of course, the use of the clothes dryer 10 is not limited to clothes.

[0089] The components and technical solutions of the dryer 10 of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0090] like Figure 1 As shown, the main body of the dryer 10 may include a casing (not shown in the figure), which can form a compartment in which various components such as the inner drum 100 and the fan 300 can be housed. The casing is provided with an openable door. For example, the casing may include a top wall and a bottom wall arranged in the height direction of the dryer 10, and a side wall connecting the top and bottom walls. The door may be located on the side wall. The user can open the door to place clothes into the drying chamber 110 of the inner drum 100, allowing the dryer 10 to dry the clothes. Alternatively, the user can also remove the dried clothes through the door.

[0091] The dryer 10 may include a support plate 400, and an inner drum 100 may be disposed on the support plate 400. Both the support plate 400 and the inner drum 100 are located within the main body; for example, both may be located within the machine compartment. The support plate 400 may be parallel or approximately parallel to the height direction of the dryer 10; that is, the support plate 400 may be vertically or approximately vertically disposed within the machine compartment. The support plate 400 is located on the side of the machine compartment away from the door and may face the door. Correspondingly, the inner drum 100 is located between the support plate 400 and the door, and the opening of the drying chamber 110 faces the door. Thus, the user can remove and load clothes from the drying chamber 110 through the door.

[0092] Please combine Figure 1 and Figure 2 The bottom plate 120 of the inner cylinder 100 can be circular or approximately circular, and the cylinder side wall 130 of the inner cylinder 100 is cylindrical. Correspondingly, the radial section of the cylinder side wall 130 can be circular or approximately circular, and the radius of the radial section of the cylinder side wall 130 can be equal to or approximately equal to the radius of the bottom plate 120.

[0093] The cylindrical sidewall 130 can be adjacent to the bottom plate 120 of the inner cylinder 100 to jointly form the drying chamber 110. The extending direction of the cylindrical sidewall 130, i.e., its axial direction, can be perpendicular or approximately perpendicular to the bottom plate 120. One end of the cylindrical sidewall 130 in the extending direction is connected to the bottom plate 120 and surrounds its edge; the other end of the cylindrical sidewall 130 in the extending direction faces the chamber door and forms the opening of the drying chamber 110.

[0094] The inner cylinder 100 is rotatably connected to the support plate 400 and is rotatably disposed within the main body. For example, the base plate 120 can be spaced apart from the support plate 400 parallel or approximately parallel, and the inner cylinder 100 can be rotatably connected to the support plate 400 via the base plate 120. The rotation axis of the inner cylinder 100 can be parallel to the central axis of the base plate 120 and can be collinear with the central axis of the base plate 120. The rotation axis of the inner cylinder 100 can also be parallel to the central axis of the cylinder side wall 130 and can be collinear with the central axis of the cylinder side wall 130.

[0095] Correspondingly, the orientation of the first air outlet 121 can be parallel to the rotation axis of the inner drum 100. Hot air blown into the drying chamber 110 from the first air outlet 121 can be directed towards the clothes in a direction parallel to the rotation axis of the inner drum 100. Multiple first air outlets 121 are spaced apart on the base plate 120, and each first air outlet 121 can blow air towards clothes in different positions within the drying chamber 110, ensuring the drying efficiency and effect of the dryer 10. This application embodiment does not limit the number, shape, size, or arrangement of the first air outlets 121, as long as the first air outlets 121 can introduce hot air from the drying channel into the drying chamber 110.

[0096] In some implementations, the dryer 10 may further include a drive unit that is connected to the inner drum 100 and is used to drive the inner drum 100 to rotate. For example, the drive unit may include at least one of a series motor, a brushless DC motor, or a switched reluctance motor.

[0097] With this configuration, during the drying process, the inner drum 100 rotates within the main body, which can tumble the clothes and prevent them from piling up, thus improving drying efficiency and drying effect.

[0098] In some implementations, the dryer 10 may also include a heating device for heating the air within the drying duct 200, thereby creating hot air within the drying duct 200 for drying. Exemplarily, the heating device may include at least one of a resistance heating wire, a heat pump, or a ceramic heater.

[0099] Please combine Figure 2 and Figure 3 The drying air duct 200 can be located on the side of the bottom plate 120 away from the cylinder side wall 130. Correspondingly, in the direction parallel to the rotation axis of the inner cylinder 100, the drying air duct 200, the air outlet 210, and the drying chamber 110 are arranged in sequence, and the air outlet 210 is connected between the drying air duct 200 and the drying chamber 110.

[0100] In one example, the dryer 10 may further include a cover plate 500, which may be disposed on the side of the support plate 400 opposite to the inner drum 100, and together with the support plate 400, form a portion of the drying duct 200. The dryer 10 may also include a flexible seal 600, which may be disposed on the side of the support plate 400 near the inner drum 100, and connected between the support plate 400 and the inner drum 100. The flexible seal 600 may be annular, forming another portion of the drying duct 200. The support plate 400 has an air duct opening 410 for connecting the drying ducts 200 located in different parts on both sides of the support plate 400. The side of the flexible seal 600 near the inner drum 100 forms an air outlet 210, and may be in close contact with the inner drum 100. Correspondingly, the base plate 120 is arranged opposite to the air outlet 210 so that the air outlet 210 communicates with the first air outlet 121 and the drying chamber 110. The flexible sealing element 600 can be in close contact with either the base plate 120 or the cylinder side wall 130.

[0101] In the above example, the flexible seal 600 can seal the gap between the support plate 400 and the inner cylinder 100, allowing hot air in the drying duct 200 to flow into the first air outlet 121 through the drying duct 200. Furthermore, the flexible seal 600 can undergo elastic deformation to support the inner cylinder 100, enabling the inner cylinder 100 to rotate relatively stably.

[0102] In some implementations, the surface of the flexible seal 600 near the inner cylinder 100 may be provided with a sound-absorbing and noise-reducing material, or the flexible seal 600 may be made of a sound-absorbing and noise-reducing material. This configuration can reduce the noise of the inner cylinder 100 during rotation, improving the user experience. For example, the sound-absorbing and noise-reducing material may include various materials such as polyurethane (PU).

[0103] A fan 300 can be installed within the drying duct 200 to blow hot air from the drying duct 200 to the air outlet 210. For example, the fan 300 can be installed between the cover plate 500 and the support plate 400, located within the drying duct 200 on the side of the support plate 400 away from the inner cylinder 100. The fan 300 may include at least one of a centrifugal fan 300 or an axial flow fan 300.

[0104] Please combine Figures 1 to 3The lifting rib 140 extends along the extension direction of the cylinder sidewall 130. One end of the lifting rib 140 is connected to the bottom plate 120, and the other end faces the opening of the drying chamber 110. An opening 142 is located at the end of the lifting rib 140 closest to the bottom plate 120. The lifting rib 140 is connected to the bottom plate 120 to enclose the opening 142, and simultaneously covers the connecting opening 122, allowing communication between the connecting opening 122 and the opening 142. There can be a gap between the end of the lifting rib 140 facing the opening of the drying chamber 110 and the opening of the drying chamber 110; that is, the lifting rib 140 can be spaced apart from the opening of the drying chamber 110.

[0105] In the above example, the geometric centers of the connecting port 122 and the base plate 120 are spaced apart radially from each other in the base plate 120, and the connecting port 122 and the lifting rib 140 are positioned relative to each other. Here, "relatively positioned" can be understood as the connecting port 122 and the lifting rib 140 being arranged sequentially in the extending direction of the cylinder sidewall 130. On a plane parallel to the base plate 120, the projection of the connecting cavity 141 can overlap with the projection of the opening 142, and the projection of the connecting port 122 can be located within the projections of the connecting cavity 141 and the opening 142, or the projection of the connecting port 122 can also overlap with the projections of the connecting cavity 141 and the opening 142.

[0106] Therefore, the hot air in the drying duct 200 can pass through the connecting port 122 and the opening 142 in a straight line and enter the connecting cavity 141. The flow of hot air is relatively smooth, which is conducive to improving the efficiency of the dryer 10.

[0107] Alternatively, "relative setting" can also be understood as the connection port 122 being closer to the connection cavity 141 than the first air outlet 121 in the direction perpendicular to the central axis of the inner cylinder 100.

[0108] Multiple second air outlets 143 can be provided, and each second air outlet 143 can be arranged in at least one row along the extending direction of the lifting rib 140. For example Figure 1 As shown, the second air outlets 143 can be arranged in a row, or as shown in the diagram. Figure 4 As shown, each of the second air outlets 143 can also be arranged in four columns. Of course, in other examples, each of the second air outlets 143 can also be arranged in two columns, three columns, or five columns, etc.

[0109] With this configuration, each of the second air outlets 143 can blow air onto clothes in different positions within the drying chamber 110, thereby ensuring the drying efficiency and drying effect of the dryer 10.

[0110] The orientation of the second air outlet 143 is at an angle to the orientation of the first air outlet 121. Correspondingly, the airflow direction of the hot air blown out of the first air outlet 121 is at an angle to the airflow direction of the hot air blown out of the second air outlet 143. Thus, the hot air blown out of the first air outlet 121 and the hot air blown out of the second air outlet 143 can dry clothes from different directions.

[0111] In one example, the second air outlet 143 may be positioned facing the central axis of the drying cylinder, and the orientation of the second air outlet 143 may be perpendicular or approximately perpendicular to the central axis of the drying cylinder. Correspondingly, the orientation of the second air outlet 143 may be perpendicular or approximately perpendicular to the orientation of the first air outlet 121.

[0112] In other examples, the second air outlet 143 may also be positioned not to face the central axis of the drying cylinder.

[0113] In the above example, different second air outlets 143 can face different directions to dry clothes from different directions while improving the diffusion efficiency of hot air in the drying chamber 110, thereby improving drying efficiency and drying effect.

[0114] In some embodiments, please refer to Figure 4 , Figure 5 as well as Figure 6 In order to increase the area of ​​the connecting port 122 and allow more hot air to enter the connecting cavity 141 from the connecting port 122, the lifting rib 140 also includes a lifting rib body 144 and a connecting part 145 connected to the lifting rib body 144.

[0115] The second air outlet 143 and at least a portion of the connecting cavity 141 are disposed on the lifting rib body 144, and the opening 142 is disposed on the connecting portion 145. The connecting cavity 141 extends from the connecting portion 145 to the lifting rib body 144. The lifting rib body 144 is connected to the cylinder sidewall 130 and the bottom plate 120, and extends along the extending direction of the cylinder sidewall 130. In the extending direction of the lifting rib body 144, the connecting portion 145 is located on the side of the lifting rib body 144 facing the bottom plate 120; in the direction perpendicular to the extending direction of the lifting rib body 144, the connecting portion 145 is located on the side of the lifting rib body 144 closer to the central axis of the inner cylinder 100. The connecting portion 145 is connected to the bottom plate 120 and covers the outside of the connecting opening 122 to connect the opening 142 and the connecting opening 122.

[0116] Because the connecting part 145 and the lifting rib body 144 are arranged in a direction perpendicular to the central axis of the inner drum 100, and the connecting part 145 protrudes from the lifting rib body 144 toward the central axis of the inner drum 100, the cross-sectional area of ​​the connecting opening 122 is not limited by the size of the lifting rib body 144. This allows for an increase in the area of ​​the connecting opening 122, enabling more hot air to enter the connecting cavity 141 from the connecting opening 122 and be blown into the drying cavity 110 through the second air outlet 143, thereby improving the drying efficiency and drying effect of the dryer 10. Furthermore, the connecting opening 122 is closer to the central axis of the inner drum 100, making the connecting opening 122 easier to manufacture.

[0117] In one example, the entire structure of the connecting portion 145 can be located within the drying chamber 110 and cover the connecting opening 122. Correspondingly, the projected area of ​​the connecting portion 145 on the base plate 120 can be larger than the cross-sectional area of ​​the connecting opening 122, and the projection of the connecting opening 122 on the base plate 120 can be within the projection of the connecting portion 145 on the base plate 120. Alternatively, the projected area of ​​the connecting portion 145 on the base plate 120 can be equal to the cross-sectional area of ​​the connecting opening 122, and the projection of the connecting opening 122 on the base plate 120 can overlap with the projection of the connecting portion 145 on the base plate 120.

[0118] In another example, please refer to Figure 6 and Figure 7 The connecting portion 145 can penetrate the communicating opening 122. A part of the structure of the connecting portion 145 is located inside the drying chamber 110, and another part of the structure of the connecting portion 145 can be located on the side of the bottom plate 120 away from the drying chamber 110, that is, outside the drying chamber 110. The opening 142 is located at the bottom end of the connecting portion 145, that is, the opening 142 is located on at least a part of the connecting portion 145 outside the drying chamber 110.

[0119] This design facilitates the installation of the lifting rib 140 onto the base plate 120, and allows hot air from the drying duct 200 to enter the connecting cavity 141 through the opening 142. Furthermore, it reduces the volume of the connecting part 145 protruding from the base plate 120, making the base plate 120 flatter, reducing the impact of the connecting part 145 on the clothes inside the drying drum, and improving the visual appeal of the dryer 10.

[0120] In the above example, the connecting part 145 may be connected to the edge of the communication port 122, or there may be a gap between the connecting part 145 and the edge of the communication port 122.

[0121] In one embodiment, the lifting rib body 144 has a first outer surface 1441, which includes the outer surface of the lifting rib body 144 facing into the drying chamber 110. The connecting portion 145 has a second outer surface 1451, which includes the outer surface of the connecting portion 145 facing into the drying chamber 110. The first outer surface 1441 matches the appearance of the drum sidewall 130, and the second outer surface 1451 matches the appearance of the bottom plate 120. This improves the visual appeal of the dryer 10.

[0122] The "appearance condition" can include color, surface treatment process, or gloss level. In one example, the first appearance surface 1441 can match the color of the cylinder sidewall 130, and the second appearance surface 1451 can match the color of the base plate 120. In another example, the first appearance surface 1441 and the cylinder sidewall 130 can be treated with the same surface treatment process, and the second appearance surface 1451 and the base plate 120 can be treated with the same surface treatment process, which can include frosting or brushing. In yet another example, the first appearance surface 1441 can match the gloss level of the cylinder sidewall 130, and the second appearance surface 1451 can match the gloss level of the base plate 120.

[0123] In the above example, the lifting rib body 144 and the connecting portion 145 can be integrally formed. For example, the lifting rib body 144 and the connecting portion 145 can be integrally formed parts manufactured by at least one of the following processes: injection molding or compression molding. Alternatively, the lifting rib body 144 and the connecting portion 145 can also be formed by at least one of the following connection methods: bonding or snap-fitting.

[0124] In some embodiments, in order to facilitate adjustment of the position of the communication port 122 and simplify the structure of the lifting rib 140, this application also provides another dryer 10.

[0125] Please refer to Figure 2 , Figure 3 as well as Figure 8 The dryer 10 also includes an air duct component 700, which is located on the side of the base plate 120 away from the drying chamber 110 and between the base plate 120 and the air outlet 210 of the drying air duct 200. The air duct component 700 has a first air duct 710, which is opposite to and communicates with the air outlet 210, and is also opposite to the first air outlet 121. Thus, the first air duct 710 can be used to blow hot air from the drying air duct 200 into the drying chamber 110 in sequence through the air outlet 210, the first air duct 710, and the first air outlet 121 to dry the clothes.

[0126] The air duct component 700 also has a second air duct 720, which connects the first air duct 710 and the connecting port 122. Thus, the second air duct 720 can be used to blow hot air in the drying air duct 200 sequentially through the air outlet 210, the first air duct 710 and the second air duct 720 into the connecting port 122, thereby causing the hot air to be blown into the drying chamber 110 through the connecting cavity 141 and the second air outlet 143 to dry the clothes.

[0127] With this configuration, the second air duct 720 can be used to guide hot air from the first air duct 710 into the connecting port 122, so that the connecting port 122 does not need to be directly connected to the air outlet 210 of the drying air duct 200, allowing for more flexible placement of the connecting port 122. For example, the connecting port 122 may not face the opening 142, and may be spaced apart from the opening 142.

[0128] In one example, the first end 721 of the second air duct is connected to the first air duct 710, and the second end 722 of the second air duct is configured to be opposite to and connected to the connection port 122. Thus, hot air in the first air duct 710 can be blown into the connecting cavity 141 in sequence through the first end 721 of the second air duct, the second end 722 of the second air duct, and the connection port 122.

[0129] In the radial direction of the base plate 120, the connecting port 122 and the second end 722 of the second air duct are closer to the cylinder side wall 130 than the first end 721 of the second air duct. This arrangement allows the second air duct 720 to guide the hot air in the first air duct 710 to flow radially towards the cylinder side wall 130 along the base plate 120. The connecting port 122 can be located on the base plate 120 near the cylinder side wall 130 without the first air outlet 121, reducing the impact of the connecting port 122 on the first air outlet 121. This allows the connecting port 122 to be opened without reducing or minimizing the reduction of the first air outlet 121, which is beneficial for ensuring the drying efficiency and drying effect of the dryer 10.

[0130] In the above example, the air duct component 700 is located between the base plate 120 and the support plate 400. For example, the air duct component 700 can be located between the flexible seal 600 and the base plate 120, so that the first air duct 710 can be arranged opposite to and connected to the air outlet 210 formed by the flexible seal 600.

[0131] The flexible seal 600 can be in close contact with the air duct component 700, thereby allowing the flexible seal 600 to undergo elastic deformation to support the air duct component 700 and enable the inner cylinder 100 to rotate relatively stably. In an example where the flexible seal 600 is made of sound-absorbing and noise-reducing material, the surface of the flexible seal 600 near the inner cylinder 100 can be provided with such material. This material can reduce the noise generated by friction between the air duct component 700 and the flexible seal 600 during the rotation of the inner cylinder 100, thus improving the user experience.

[0132] In some implementations, the air duct component 700 may include an annular air duct body 730, which is disposed on the base plate 120, and the central axis of the air duct body 730 may be collinear with the rotation axis of the inner cylinder 100 so as to rotate with the inner cylinder 100. One of the two end faces disposed opposite each other on the central axis of the air duct body 730 is connected to the base plate 120, and the other is connected to the drying air duct 200, thereby forming a first air duct 710, which is located in the hollow portion of the annular air duct body 730. Exemplarily, the air duct body 730 may be connected to the drying air duct 200 by a flexible seal 600.

[0133] Correspondingly, the cross-section of the first air duct 710 can be circular. One end of the first air duct 710 faces the flexible sealing element 600 and is connected to the air outlet 210, while the other end of the first air duct 710 faces the base plate 120 and is connected to the first air outlet 121.

[0134] The air duct component 700 also includes an air guide component 740, which forms at least a portion of the air duct wall of the second air duct 720. The air guide component 740 can be connected to the base plate 120 to enclose the second air duct 720 and connect the second air duct 720 to the communication port 122. The second air duct 720 extends along the extending direction of the air guide component 740, and the first end 721 and the second end 722 of the second air duct are spaced apart in the extending direction of the air guide component 740. For example, the air guide component 740 can extend radially along the base plate 120, whereby the second end 722 of the second air duct can be positioned closer to the cylinder sidewall 130 relative to the first end 721 of the second air duct.

[0135] The main body of the air duct 730 has a notch 731 on its inner edge near the first air duct 710. The notch 731 faces inward and communicates with the first air duct 710. One end of the air guide 740 is located at the notch 731. The air guide 740 extends away from the first air duct 710 and passes through the main body of the air duct 730. At least a portion of the air guide 740 is located within the main body of the air duct 730. The other end of the air guide 740 can extend out of the main body of the air duct 730. Correspondingly, the first end 721 of the second air duct can be located at the end of the air guide 740 located at the notch 731 and communicates with the first air duct 710 through the notch 731. The second end 722 of the second air duct can be located at the end of the air guide 740 extending out of the main body of the air duct 730.

[0136] Therefore, the air guide 740 can be used to form a second air duct 720 and guide the hot air in the first air duct 710 into the connecting port 122 through the second air duct 720. The connecting port 122 does not need to be directly connected to the air outlet 210 of the drying air duct 200, so that the position of the connecting port 122 can be set more freely.

[0137] Understandably, the air guide 740 can be made of sheet metal to ensure its own strength while having a thinner profile, thereby reducing the space occupied by the air guide 740's own structure on the second air duct 720, and reducing the volume and structural dimensions of the entire air duct component 700. Alternatively, the air guide 740 can also be made of high-strength plastic.

[0138] In this way, by using structures such as the air guide 740 and the air duct body 730, a second air duct 720 and other air guide structures are set on the outside of the base plate 120, that is, on the side away from the drying chamber 110. Hot air can be guided to the connecting chamber 141 through the second air duct 720. The lifting rib 140 itself only needs to ensure the connection with the base plate 120 and the circulation of hot air inside the lifting rib 140. It does not need to be equipped with a more complex connection part 145 and other structures, and the overall structure of the lifting rib 140 can be simplified.

[0139] In the above embodiments, multiple lifting ribs 140 and connecting ports 122 can be provided. Each lifting rib 140 can be spaced apart circumferentially along the cylinder sidewall 130, and each connecting port 122 can be arranged opposite to a different lifting rib 140. For example, two lifting ribs 140 and two connecting ports 122 can be provided, and the two lifting ribs 140 can be arranged opposite to each other on both sides of the cylinder sidewall 130. Alternatively, three or more lifting ribs 140 and connecting ports 122 can be provided.

[0140] This design helps to prevent small amounts of clothing from accumulating at the bottom of the drum side wall 130, and can increase the number of second air outlets 143, thereby improving the drying efficiency and drying effect of the dryer 10.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the air conditioner of this application, and are not intended to limit it. Although the air conditioner of this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
