Description

Technical Field

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

[0002] With the fast pace of life, the demand for washing and drying equipment such as washing machines and dryers is increasing as people do housework. In related technologies, dryers usually have a built-in rotating inner drum. When working, clothes can tumble continuously in the inner drum as it rotates, and hot air is blown into the inner drum to dry the clothes.

[0003] However, most clothes dryers on the market currently suffer from poor drying efficiency. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the related technologies, this application provides a clothes dryer to solve the problem of poor drying efficiency in the related technologies.

[0005] To address the aforementioned technical problems, in a first aspect, this application provides a clothes dryer, which includes:

[0006] main body;

[0007] The inner drum is rotatably disposed inside the main body, and the interior of the inner drum forms a drying chamber for drying clothes;

[0008] A drying air duct is disposed outside the inner cylinder and is used to generate hot air for drying. The drying air duct has an air outlet.

[0009] A fan is installed inside the drying air duct and is used to blow hot air from the drying air duct to the air outlet.

[0010] The inner cylinder includes:

[0011] A first base plate is provided with a first air outlet, which is connected to the air outlet so that the hot air in the drying air duct can be blown into the drying chamber in a first direction through the first air outlet.

[0012] The cylinder sidewall is wrapped around the edge of the first bottom plate, and the first bottom plate and the cylinder sidewall together form the drying chamber;

[0013] A lifting rib is protruding from the side wall of the inner drum and located inside the drying chamber. The lifting rib is used to lift the clothes inside the drying chamber when the inner drum rotates.

[0014] An air guide is provided on the side wall of the cylinder and located inside the drying chamber. The air guide and the lifting rib are arranged at intervals in the circumferential direction of the inner cylinder. A second air outlet is provided on the air guide and the second air outlet is connected to the air outlet so that the hot air in the drying air duct is blown into the drying chamber through the second air outlet in a second direction, which is different from the first direction.

[0015] With this configuration, since the first air outlet is provided on the first bottom plate of the inner drum and is connected to the air outlet of the drying air duct, hot air in the drying air duct is blown into the drying chamber in a first direction. Since the second air outlet is provided on the air guide part of the side wall of the drum and is connected to the air outlet of the drying air duct, hot air in the drying air duct is blown into the drying chamber in a second direction different from the first direction. Therefore, as the lifting ribs rotate with the inner drum and continuously lift the clothes to make them tumble, hot air from the first and second air outlets can fully and evenly contact and penetrate into the tumbling clothes. This greatly increases the contact area and efficiency between hot air and clothes, avoiding the problems of insufficient drying of clothes and inefficient use of hot air caused by air outlets in one direction. Thus, the drying efficiency of the dryer is significantly improved.

[0016] Optionally, the air guide includes:

[0017] The air guide body protrudes from the side wall of the cylinder and extends along the axial direction of the inner cylinder. The second air outlet is located on the side of the air guide body facing the central axis of the inner cylinder.

[0018] The air guide body has a first protrusion height in the radial direction of the inner cylinder, and the lifting rib has a second protrusion height in the radial direction of the inner cylinder, wherein the first protrusion height is smaller than the second protrusion height.

[0019] With this design, firstly, the air guide body protruding from the side wall of the drum can provide a moderate guiding effect on the clothes as they rotate and tumble with the inner drum, helping to slightly separate stacked clothes and reduce the situation where clothes are tightly attached to the air guide body. This allows the hot air blown out from the second air outlet to penetrate the gaps in the clothes more easily, thereby further improving the drying efficiency.

[0020] Secondly, extending the main body of the air guide along the axial direction of the inner cylinder can increase the distribution range of the main body of the air guide in the axial direction of the inner cylinder, which in turn helps to increase the distribution range of the second air outlet in the axial direction of the inner cylinder to a certain extent. This helps to increase the air delivery range of the second air outlet in the axial direction of the inner cylinder, which in turn helps to increase the contact area between hot air and clothes, and further improves drying efficiency.

[0021] In addition, the height of the first protrusion of the air guide body is set to be less than the height of the second protrusion of the lifting rib. In this way, during the rotation of the inner drum, the lifting effect of the lifting rib with a larger protrusion on the clothes helps to avoid the clothes from excessively squeezing the air guide body, thereby helping to prevent the clothes from clogging the second air outlet and ensuring the positive airflow of the second air outlet.

[0022] Optionally, the cross-sectional shape of the air guide body is arc-shaped, and the cross-section is perpendicular to the central axis of the inner cylinder.

[0023] This design allows the air guide body to have a curved surface. Compared to sharp or flat structures, the curved surface significantly reduces the risk of clothing rubbing or snagging against the air guide body when the inner drum rotates, providing better protection, especially for soft fabrics such as silk and wool. Simultaneously, when clothing tumbles with the lifting ribs and comes into contact with the curved surface, the curved structure helps the clothing slide smoothly, preventing the air guide body from lifting the clothing and reducing the accumulation of clothing near the air guide body, further preventing the second air outlet from becoming blocked.

[0024] Optionally, the main body of the air guide is an air guide shell, and a first air duct is formed between the air guide shell and the side wall of the cylinder, and the first air duct is connected between the air outlet and the second air outlet hole.

[0025] With this configuration, the first air duct can guide and converge the hot air, which helps to prevent the hot air from diffusing and causing a decrease in air volume or temperature before reaching the second air outlet. This helps to ensure that the hot air can be delivered to the second air outlet at a stable flow rate and temperature, maximizing the drying capacity of the hot air and thus ensuring the drying effect of the hot air.

[0026] In addition, setting the main body of the air guide as an air guide shell helps to reduce the weight of the air guide, which in turn helps to reduce the weight of the entire inner cylinder, and facilitates the rotation of the inner cylinder.

[0027] Optionally, the drying air duct is disposed on the side of the first base plate away from the drying chamber, and the first base plate is provided with a first connecting port, which is connected to the air outlet;

[0028] The air guide section also includes:

[0029] A connecting shell is connected to the side of the air guide shell facing the first base plate and covers the outside of the first connecting opening. The connecting shell and the first base plate form a second air duct. The second air duct connects the first connecting opening and the first air duct, so that the first air duct connects the air outlet and the second air outlet.

[0030] With this configuration, since the drying air duct is located on the side of the first bottom plate away from the drying chamber, the connection between the first air duct and the drying air duct is facilitated by the second air duct formed by the connecting shell and the first bottom plate, and the first connecting port on the first bottom plate. This eliminates the need for complex modifications to the cylinder side wall structure and simplifies the structural design of the cylinder side wall.

[0031] In addition, the connected shell design helps to further reduce the weight of the air guide, which in turn helps to further reduce the weight of the inner cylinder and makes it easier to drive the inner cylinder to rotate.

[0032] Optionally, multiple first connecting ports and multiple air guides are provided, with each of the multiple first connecting ports corresponding to one of the multiple air guides.

[0033] This setup avoids uneven airflow distribution caused by multiple air guides sharing a single connection port, ensuring that each air guide receives a sufficient and stable supply of hot air. This, in turn, allows each air guide's second air outlet to output sufficient and stable hot air, further guaranteeing the drying effect.

[0034] On the other hand, multiple air guides can form multiple air outlet areas in the circumference of the inner drum, allowing hot air to act on the clothes from different circumferential positions. This helps to eliminate blind spots caused by a single air guide, thereby further improving drying efficiency and enhancing the drying effect.

[0035] Optionally, multiple lifting ribs and multiple air guides are provided, and in the circumferential direction of the inner cylinder, multiple lifting ribs and multiple air guides are alternately arranged and evenly distributed.

[0036] This design allows the evenly distributed lifting ribs to lift the clothes simultaneously from different circumferential positions when the inner drum rotates. This helps avoid localized stacking of clothes due to the concentration of lifting ribs, and allows the clothes to tumble more fully and remain in a dynamically loose state, creating more favorable conditions for hot air contact.

[0037] On the other hand, the evenly distributed multiple air guides can form multiple evenly distributed air outlet areas in the circumference of the inner drum. This allows hot air to act evenly on the clothes in the circumference of the inner drum, which is more conducive to eliminating the blind spots in air outlet caused by a single air guide, and thus further improving drying efficiency and enhancing drying effect.

[0038] In addition, since the axis of the inner drum is perpendicular to the vertical, when the inner drum stops rotating, the hot air output from the first air outlet on the first bottom plate will pass over the clothes. And through multiple air guides evenly distributed along the circumference of the inner drum, the hot air can still pass through the clothes, that is, the clothes can still be dried, which helps to reduce the waste of heat energy when the inner drum stops rotating.

[0039] Optionally, the air guide is provided with a plurality of second air outlets, and the plurality of second air outlets are arranged in at least one row in the axial direction of the inner cylinder.

[0040] With this design, on the one hand, the second air outlet, arranged along the axial direction, allows the hot air output to no longer be limited to a certain axial position of the inner drum, but can increase the axial air delivery range of the second air outlet, thereby increasing the axial contact area between the hot air and the clothes, and further improving the drying efficiency.

[0041] On the other hand, at least one row of second air outlets can further increase the density of air coming out of the second air outlets, increase the frequency of contact between hot air and clothes, and thus further improve drying efficiency.

[0042] Optionally, the main body includes:

[0043] The second base plate is connected to at least one of the first base plate and the cylinder sidewall, and is located on the side of the first base plate away from the cylinder sidewall. The second base plate is provided with a second communication port, and a first space is formed between the second base plate and the first base plate. The first space is connected to the first air outlet and the second air outlet.

[0044] A back panel is connected to the second bottom plate and is located on the side of the second bottom plate away from the first bottom plate. A second space is formed between the back panel and the second bottom plate, and the second connecting port connects the second space and the first space.

[0045] A fan cover is connected to the back panel and is located on the side of the back panel away from the second bottom plate. The fan cover and the back panel are used to form the drying air duct. The air outlet is located on the back panel and connects the drying air duct and the second space.

[0046] This arrangement allows the fan cover, back panel, second bottom plate, and first bottom plate to be arranged in layers along the axial direction of the inner cylinder. This orderly separation of the drying duct, second space, and first space from the drying chamber along the axial direction of the inner cylinder prevents direct communication between the drying duct and the drying chamber. This helps to prevent the humid air in the drying chamber from contacting the components in the drying duct, thus avoiding moisture damage to the components and extending the service life of the components in the drying duct. This also helps to ensure the long-term stable operation of the dryer.

[0047] Optionally, the projection of the second connecting port along the axial direction of the inner cylinder has a first projected area, and the projection of the second air outlet along the axial direction of the inner cylinder has a second projected area, wherein the first projected area is larger than the second projected area.

[0048] The second communication port is provided in multiple ways, and the multiple second communication ports are evenly distributed in the circumferential direction of the inner cylinder.

[0049] This configuration ensures that, on the one hand, sufficient hot air can enter the first space through the second connecting port with a larger projected area, and on the other hand, sufficient hot air can be output through the first and second air outlets.

[0050] On the other hand, multiple circumferentially evenly distributed second connecting ports can form a circumferentially uniform airflow field in the first space, thereby preventing the local accumulation of hot air in the first space and allowing the first and second air outlets in different circumferential directions to obtain an equal amount of hot air, thus keeping the airflow intensity of each first air outlet consistent and keeping the airflow intensity of each second air outlet consistent.

[0072] As described in the background section of this application, with the accelerating pace of life, the demand for washing and drying equipment such as washing machines and dryers is increasing in household chores. In related technologies, dryers typically have a built-in rotating inner drum. During operation, clothes tumble continuously within the inner drum as it rotates, and hot air is blown into the inner drum to dry the clothes.

[0073] However, most clothes dryers on the market currently suffer from poor drying efficiency.

[0074] In view of the above-mentioned problems, this application provides a clothes dryer to solve the problem of poor drying efficiency in related technologies.

[0075] The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings:

[0076] In some alternative embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the dryer includes a main body 1 and an inner drum 2, wherein the inner drum 2 is rotatably disposed inside the main body 1, and the interior of the inner drum 2 forms a drying chamber 21 for drying clothes.

[0077] With this configuration, when the inner drum 2 rotates, the clothes inside the drying chamber 21 can continuously tumble along with the rotation of the inner drum 2. This allows the clothes to come into full contact with the hot air, avoiding the problem of uneven drying in certain areas, and thus greatly improving the drying effect, allowing all parts of the clothes to reach the ideal drying degree.

[0078] In some alternative embodiments, such as Figure 3 As shown, the dryer also includes a drying air duct 3, which is located outside the inner drum 2 and is used to generate hot air for drying. The drying air duct 3 has an air outlet 31.

[0079] This configuration, through the drying air duct 3, generates hot air for drying, which can continuously provide a stable heat source for the drying process. This ensures that there is always sufficient hot air in the drying chamber 21 to participate in the drying of clothes, effectively avoiding problems such as slow drying speed and uneven drying of clothes due to insufficient hot air supply, and greatly improving the drying effect and efficiency.

[0080] In some alternative embodiments, such as Figure 3 and Figure 4 As shown, the dryer also includes a fan 4, which is installed in the drying duct 3 and is used to blow the hot air in the drying duct 3 to the air outlet 31.

[0081] With this configuration, the fan 4 can directly act on the hot air in the drying duct 3. It can provide stable and controllable power to the hot air through active air supply, avoiding problems such as slow hot air flow and limited delivery distance caused by natural convection. It ensures that the hot air can enter the drying chamber 21 through the air outlet 31 with sufficient wind speed and pressure, which greatly improves the circulation efficiency of the hot air in the entire delivery path and reduces the energy waste caused by the stagnation of hot air.

[0082] In some alternative embodiments, such as Figure 4 As shown, the inner cylinder 2 includes a first bottom plate 22, a cylinder side wall 23, lifting ribs 24, and an air guide section 25. Among them, as... Figure 5 As shown, a first air outlet 221 is provided on the first base plate 22. The first air outlet 221 is connected to the air outlet 31 so that hot air in the drying air duct 3 can pass through the first air outlet 221 along a first direction (e.g., Figure 3 (In the X direction) blown into the drying chamber 21.

[0083] like Figure 1 , Figure 2 and Figure 3 As shown, the drum sidewall 23 is wrapped around the edge of the first bottom plate 22, and the first bottom plate 22 and the drum sidewall 23 together form the drying chamber 21. Lifting ribs 24 protrude from the drum sidewall 23 and are located inside the drying chamber 21. The lifting ribs 24 are used to lift the clothes inside the drying chamber 21 when the inner drum 2 rotates. Air guides 25 are disposed on the drum sidewall 23 and are located inside the drying chamber 21, such as... Figure 2 As shown, the air guide section 25 and the lifting rib 24 are arranged at intervals along the circumference of the inner cylinder 2. Figure 6 As shown, the air guide section 25 is provided with a second air outlet 251, which is connected to the air outlet 31, so that the hot air in the drying air duct 3 can pass through the second air outlet 251 along a second direction (such as...). Figure 3 The air is blown into the drying chamber 21 in the Z direction, and the second direction is different from the first direction.

[0084] With this configuration, since the first bottom plate 22 of the inner drum 2 is provided with a first air outlet 221, and the first air outlet 221 is connected to the air outlet 31 of the drying air duct 3, the hot air in the drying air duct 3 is blown into the drying chamber 21 in the first direction. Since the air guide part 25 of the side wall 23 of the drum is provided with a second air outlet 251, and the second air outlet 251 is connected to the air outlet 31 of the drying air duct 3, the hot air in the drying air duct 3 is blown into the drying chamber 21 in a second direction different from the first direction. Therefore, as the lifting rib 24 rotates with the inner drum 2 and continuously lifts the clothes to make them tumble, the multi-directional hot air from the first air outlet 221 and the second air outlet 251 can fully and evenly contact and penetrate into the tumbling clothes, which greatly increases the contact area and efficiency between the hot air and the clothes. This avoids the problem of insufficient drying of clothes and inefficient use of hot air caused by air outlet in one direction, thereby significantly improving the drying efficiency of the dryer.

[0085] In some alternative embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the dryer includes a main body 1 and an inner drum 2, wherein the inner drum 2 is rotatably disposed inside the main body 1, and the interior of the inner drum 2 forms a drying chamber 21 for drying clothes.

[0086] like Figure 3 As shown, the dryer also includes a drying air duct 3, which is located outside the inner drum 2 and is used to generate hot air for drying. The drying air duct 3 has an air outlet 31. Figure 3 and Figure 4 As shown, the dryer also includes a fan 4, which is installed in the drying duct 3 and is used to blow the hot air in the drying duct 3 to the air outlet 31.

[0087] like Figure 4 As shown, the inner cylinder 2 includes a first bottom plate 22, a cylinder side wall 23, lifting ribs 24, and an air guide section 25. Among them, as... Figure 5 As shown, a first air outlet 221 is provided on the first base plate 22. The first air outlet 221 is connected to the air outlet 31 so that hot air in the drying air duct 3 can pass through the first air outlet 221 along a first direction (e.g., Figure 3 (In the X direction) blown into the drying chamber 21.

[0088] like Figure 1 , Figure 2 and Figure 3 As shown, the drum sidewall 23 is wrapped around the edge of the first bottom plate 22, and the first bottom plate 22 and the drum sidewall 23 together form the drying chamber 21. Lifting ribs 24 protrude from the drum sidewall 23 and are located inside the drying chamber 21. The lifting ribs 24 are used to lift the clothes inside the drying chamber 21 when the inner drum 2 rotates. Air guides 25 are disposed on the drum sidewall 23 and are located inside the drying chamber 21, such as... Figure 2 As shown, the air guide section 25 and the lifting rib 24 are arranged at intervals along the circumference of the inner cylinder 2. Figure 6 As shown, the air guide section 25 is provided with a second air outlet 251, which is connected to the air outlet 31, so that the hot air in the drying air duct 3 can pass through the second air outlet 251 along a second direction (such as...). Figure 3 The air is blown into the drying chamber 21 in the Z direction, and the second direction is different from the first direction.

[0089] With this configuration, since the first bottom plate 22 of the inner drum 2 is provided with a first air outlet 221, and the first air outlet 221 is connected to the air outlet 31 of the drying air duct 3, the hot air in the drying air duct 3 is blown into the drying chamber 21 in the first direction. Since the air guide part 25 of the side wall 23 of the drum is provided with a second air outlet 251, and the second air outlet 251 is connected to the air outlet 31 of the drying air duct 3, the hot air in the drying air duct 3 is blown into the drying chamber 21 in a second direction different from the first direction. Therefore, as the lifting rib 24 rotates with the inner drum 2 and continuously lifts the clothes to make them tumble, the multi-directional hot air from the first air outlet 221 and the second air outlet 251 can fully and evenly contact and penetrate into the tumbling clothes, which greatly increases the contact area and efficiency between the hot air and the clothes. This avoids the problem of insufficient drying of clothes and inefficient use of hot air caused by air outlet in one direction, thereby significantly improving the drying efficiency of the dryer.

[0090] In some alternative embodiments, the first direction extends axially along the inner cylinder 2, and the second direction extends radially along the inner cylinder 2, i.e., the first direction is perpendicular to the second direction.

[0091] With this configuration, the vertical bidirectional airflow can form a highly efficient and complementary three-dimensional hot air circulation system within the drying chamber 21. This facilitates complete coverage of the drying chamber 21, allowing hot air to fully contact the clothes from different dimensions, significantly improving heat exchange efficiency, and thus further enhancing drying efficiency.

[0092] In some alternative embodiments, the angle between the first direction and the second direction can be an acute angle or an obtuse angle. The angle between the first direction and the second direction is set flexibly. Specifically, it can be set according to actual needs. This application does not impose specific limitations on this aspect.

[0093] In some optional embodiments, a heating device (not shown in the figure) is also provided in the drying air duct 3. The heating device can be an electric heating tube or an infrared heating tube, etc. The heating device is used to heat the air in the drying air duct 3 to form hot air for drying.

[0094] With this configuration, the heating device can directly act on the air in the drying duct 3, quickly heating the air to the target drying temperature, which helps improve the efficiency of air heating and thus improves the drying efficiency.

[0095] For the air guide section 25, further, in some optional embodiments, such as Figure 6 As shown, the air guide section 25 includes an air guide section body 252, as... Figure 1 , Figure 2 and Figure 3 As shown, the main body 252 of the air guide protrudes from the side wall 23 of the cylinder and extends axially along the inner cylinder 2, as... Figure 6 As shown, the second air outlet 251 is located on one side of the air guide body 252 facing the central axis of the inner cylinder 2.

[0096] like Figure 2 As shown, the air guide body 252 has a first protrusion height h1 in the radial direction of the inner cylinder 2, and the lifting rib 24 has a second protrusion height h2 in the radial direction of the inner cylinder 2. The first protrusion height h1 is smaller than the second protrusion height h2.

[0097] With this configuration, firstly, the air guide body 252 protruding from the side wall 23 of the drum can provide a moderate guiding effect on the clothes as they rotate and tumble with the inner drum 2, helping to slightly separate the stacked clothes and reduce the situation where the clothes are tightly attached to the air guide body 252. This allows the hot air blown out from the second air outlet 251 to penetrate the gaps in the clothes more easily, which in turn helps to further improve the drying efficiency.

[0098] Secondly, by extending the air guide body 252 along the axial direction of the inner cylinder 2, the distribution range of the air guide body 252 in the axial direction of the inner cylinder 2 can be increased, which in turn helps to increase the distribution range of the second air outlet 251 in the axial direction of the inner cylinder 2 to a certain extent. This helps to increase the air delivery range of the second air outlet 251 in the axial direction of the inner cylinder 2, which in turn helps to increase the contact area between hot air and clothes, and further improves the drying efficiency.

[0099] In addition, the first protrusion height h1 of the air guide body 252 is set to be smaller than the second protrusion height h2 of the lifting rib 24. In this way, during the rotation of the inner cylinder 2, the lifting effect of the lifting rib 24 with a larger protrusion height helps to avoid the clothes from excessively squeezing the air guide body 252, thereby helping to prevent the clothes from clogging the second air outlet 251 and ensuring the positive air outlet of the second air outlet 251.

[0100] Furthermore, in some alternative embodiments, such as Figure 2 As shown, the cross-section of the air guide body 252 is arc-shaped, and the cross-section is perpendicular to the central axis of the inner cylinder 2.

[0101] This design allows the air guide body 252 to have a curved surface. Compared to a sharp or flat structure, the curved surface significantly reduces the risk of clothing rubbing or snagging against the air guide body 252 when the inner drum 2 rotates, providing better protection, especially for soft fabrics such as silk and wool. Simultaneously, when clothing tumbles with the lifting ribs 24 and comes into contact with the curved surface, the curved structure helps the clothing slide smoothly, preventing the air guide body 252 from lifting the clothing and reducing the accumulation of clothing near the air guide body 252, further preventing the second air outlet 251 from becoming blocked.

[0102] Furthermore, in some alternative embodiments, such as Figure 2 As shown, the cross-sectional shape of the air guide body 252 is semi-circular.

[0103] This design allows the air guide body 252 to have a semi-circular arc surface. The smooth, semi-circular surface completely eliminates the risk of scratches that may occur from sharp corners or irregular curved surfaces. Even if soft fabric clothing rotates at high speed with the inner drum 2 and comes into contact with the air guide body 252, it can slide smoothly along the semi-circular surface. This effectively prevents clothing from snagging and abrasion, and further prevents the air guide body 252 from lifting clothing. It also helps to further reduce the retention and accumulation of clothing near the air guide body 252, and further helps to prevent the second air outlet 251 from being blocked.

[0104] In some alternative embodiments, the cross-sectional shape of the air guide body 252 can also be a superior arc shape, a inferior arc shape, an elliptical arc shape, a rectangle or a trapezoid, etc. The shape of the cross-section of the air guide body 252 is set flexibly. Specifically, it can be set according to actual needs. This application embodiment does not make specific limitations in this regard.

[0105] Furthermore, in some alternative embodiments, such as Figure 3 As shown, the main body 252 of the air guide is an air guide shell, and a first air duct 5 is formed between the air guide shell and the side wall 23 of the cylinder. The first air duct 5 is connected between the air outlet 31 and the second air outlet 251.

[0106] With this configuration, the first air duct 5 can guide and converge the hot air, which helps to prevent the hot air from diffusing and causing a decrease in air volume or temperature before reaching the second air outlet 251. This helps to ensure that the hot air can be delivered to the second air outlet 251 at a stable flow rate and temperature, maximizing the drying capacity of the hot air and thus ensuring the drying effect of the hot air.

[0107] In addition, setting the air guide body 252 as an air guide shell is beneficial to reducing the weight of the air guide 25, which in turn is beneficial to reducing the weight of the entire inner cylinder 2, and is beneficial to facilitating the rotation of the inner cylinder 2.

[0108] In some alternative embodiments, the air guide body 252 may also be a solid structure. This configuration simplifies the structure of the air guide body 252 to some extent, as it eliminates the need to fabricate a structure within the air guide body 252 to form the first air duct 5. This facilitates the manufacturing of the air guide body 252 and also enhances its structural strength to some extent.

[0109] Furthermore, in some alternative embodiments, such as Figure 3 As shown, the drying air duct 3 is located on the side of the first base plate 22 away from the drying chamber 21, as... Figure 5 As shown, a first connecting port 222 is provided on the first base plate 22, and the first connecting port 222 is connected to the air outlet 31.

[0110] like Figure 3 and Figure 6 As shown, the air guide section 25 also includes a connecting shell 253, which is connected to the side of the air guide shell facing the first base plate 22 and covers the outside of the first connecting opening 222. The connecting shell 253 and the first base plate 22 form a second air duct 6, which connects the first connecting opening 222 and the first air duct 5 so that the first air duct 5 connects the air outlet 31 and the second air outlet 251.

[0111] With this configuration, since the drying air duct 3 is located on the side of the first bottom plate 22 away from the drying chamber 21, the first air duct 5 and the drying air duct 3 are easily connected by the second air duct 6 formed by the connecting shell 253 and the first bottom plate 22, and the first connecting port 222 provided on the first bottom plate 22. This eliminates the need for complex modifications to the structure of the cylinder side wall 23 and simplifies the structural design of the cylinder side wall 23.

[0112] In addition, the connection shell 253 helps to further reduce the weight of the air guide 25, which in turn helps to further reduce the weight of the inner cylinder 2, and makes it easier to drive the inner cylinder 2 to rotate.

[0113] In some alternative embodiments, when the first connecting port 222 is located on the side wall 23 of the cylinder, the first air duct 5 can be directly connected to the first connecting port 222. In this case, the connecting housing 253 is not required. This simplifies the structure of the air guide 25 and facilitates its processing and manufacturing.

[0114] In some alternative embodiments, the air guide 25 may be formed by a portion of the cylinder sidewall 23, that is, the second air outlet 251 is directly disposed on the cylinder sidewall 23. This arrangement simplifies the structural composition of the inner cylinder 2 and facilitates the processing, manufacturing and assembly of the inner cylinder 2.

[0115] Furthermore, in some alternative embodiments, such as Figure 2and Figure 5 As shown, multiple first connecting ports 222 and multiple air guides 25 are provided, with each of the multiple first connecting ports 222 corresponding to one of the multiple air guides 25.

[0116] This configuration avoids the problem of uneven airflow distribution caused by multiple air guides 25 sharing a single connection port, ensuring that each air guide 25 receives a sufficient and stable supply of hot air. This allows each air guide 25's second air outlet 251 to output sufficient and stable hot air, further guaranteeing the drying effect.

[0117] On the other hand, multiple air guides 25 can form multiple air outlet areas in the circumference of the inner drum 2, which allows hot air to act on the clothes from different circumferential positions. This helps to eliminate the blind spots in air outlet caused by a single air guide 25, thereby further improving drying efficiency and enhancing drying effect.

[0118] In this embodiment of the application, the number of the first connecting port 222 and the air guide 25 can be 2, 3 or more. The number of the first connecting port 222 and the air guide 25 is set flexibly. Specifically, it can be set according to actual needs. This embodiment of the application does not make a specific limitation on this.

[0119] In some alternative embodiments, such as Figure 2 As shown, multiple lifting ribs 24 and multiple air guides 25 are provided. In the circumferential direction of the inner cylinder 2, multiple lifting ribs 24 and multiple air guides 25 are alternately arranged and evenly distributed.

[0120] With this design, on the one hand, when the inner drum 2 rotates, the circumferentially evenly distributed lifting ribs 24 can simultaneously lift the clothes from different circumferential positions, which helps to avoid local stacking of clothes caused by the concentration of lifting ribs 24, and allows the clothes to tumble more fully and always remain in a dynamic loose state, creating more favorable conditions for hot air contact.

[0121] On the other hand, the evenly distributed multiple air guides 25 can form multiple evenly distributed air outlet areas in the circumference of the inner drum 2. In this way, hot air can be evenly applied to the clothes in the circumference of the inner drum 2, which is more conducive to eliminating the blind spots in air outlet caused by a single air guide 25, and thus further improving drying efficiency and enhancing drying effect.

[0122] In addition, since the axis of the inner drum 2 is perpendicular to the vertical, when the inner drum 2 stops rotating, the hot air output from the first air outlet 221 on the first bottom plate 22 will pass over the clothes. And through the multiple air guides 25 evenly distributed along the circumference of the inner drum 2, the hot air can still pass through the clothes, that is, the clothes can still be dried, which helps to reduce the heat energy waste when the inner drum 2 stops rotating.

[0123] In this embodiment, the number of lifting ribs 24 and air guides 25 can be two, three or more. The number of lifting ribs 24 and air guides 25 is set flexibly. Specifically, it can be set according to actual needs. This embodiment does not make specific limitations on this.

[0124] In some alternative embodiments, one lifting rib 24 and one air guide 25 may each be provided. This arrangement simplifies the number of lifting ribs 24 and air guides 25, thereby simplifying the structure of the inner cylinder 2 and facilitating its processing, manufacturing, and assembly.

[0125] In some optional embodiments, the air guide 25 is provided with a plurality of second air outlets 251, and the plurality of second air outlets 251 are arranged in at least one row in the axial direction of the inner cylinder 2.

[0126] With this configuration, on the one hand, the second air outlet 251 arranged along the axial direction allows the hot air output to no longer be limited to a certain axial position of the inner cylinder 2, but can increase the axial air delivery range of the second air outlet 251, thereby increasing the axial contact area between the hot air and the clothes, and further improving the drying efficiency.

[0127] On the other hand, at least one row of second air outlets 251 can further increase the density of air coming out of the second air outlets 251, increase the frequency of contact between hot air and clothes, and thus further improve drying efficiency.

[0128] In this embodiment, the second air outlet 251 can be provided with one, two or more columns. The number of columns of the second air outlet 251 is flexible and can be set according to actual needs. This embodiment does not make specific limitations on this.

[0129] In some alternative embodiments, the air guide section 25 may also be provided with a second air outlet 251, provided that the air volume of one second air outlet 251 is sufficient to meet the drying requirements. This arrangement simplifies the number of second air outlets 251 on the air guide section 25, thereby simplifying the structure of the air guide section 25 and facilitating its processing and manufacturing.

[0130] For subject 1, further, in some optional embodiments, such as Figure 3 and Figure 4 As shown, the main body 1 includes a second base plate 11, a rear back plate 12, and a fan cover plate 13. The second base plate 11 is connected to at least one of the first base plate 22 and the cylinder sidewall 23, and is located on the side of the first base plate 22 opposite to the cylinder sidewall 23. Figure 7 As shown, the second base plate 11 is provided with a second connecting port 111, and as... Figure 3As shown, a first space 7 is formed between the second base plate 11 and the first base plate 22, and the first space 7 is connected to the first air outlet 221 and the second air outlet 251.

[0131] like Figure 3 As shown, the back panel 12 is connected to the second bottom panel 11 and is located on the side of the second bottom panel 11 away from the first bottom panel 22. The back panel 12 and the second bottom panel 11 form a second space 8, and the second connecting port 111 connects the second space 8 and the first space 7.

[0132] like Figure 3 As shown, the fan cover 13 is connected to the back panel 12 and is located on the side of the back panel 12 away from the second bottom plate 11. The fan cover 13 and the back panel 12 are used to form the drying air duct 3, as shown. Figure 8 As shown, the air outlet 31 is located on the rear panel 12 and is connected to the drying air duct 3 and the second space 8.

[0133] This arrangement allows the fan cover 13, back panel 12, second bottom plate 11, and first bottom plate 22 to be arranged in layers along the axial direction of the inner cylinder 2. This orderly separation of the drying duct 3, second space 8, and first space 7 from the drying chamber 21 along the axial direction of the inner cylinder 2 prevents the drying duct 3 from being directly connected to the drying chamber 21. This also helps to prevent the humid air in the drying chamber 21 from coming into contact with the components in the drying duct 3, thus preventing the components in the drying duct 3 from getting damp. This, in turn, helps to extend the service life of the components in the drying duct 3 and helps to ensure the long-term stable operation of the dryer.

[0134] Furthermore, in some optional embodiments, the projection of the second connecting port 111 along the axial direction of the inner cylinder 2 has a first projected area, and the projection of the second air outlet 251 along the axial direction of the inner cylinder 2 has a second projected area, wherein the first projected area is larger than the second projected area.

[0135] like Figure 7 As shown, multiple second connecting ports 111 are provided, and the multiple second connecting ports 111 are evenly distributed in the circumferential direction of the inner cylinder 2.

[0136] With this configuration, on the one hand, the second connecting port 111 with a larger projected area can ensure that sufficient hot air enters the first space 7, and thus ensure that sufficient hot air is output through the first air outlet 221 and the second air outlet 251.

[0137] On the other hand, the multiple circumferentially evenly distributed second connecting ports 111 can form a circumferentially uniform airflow field in the first space 7, thereby preventing the local accumulation of hot air in the first space 7, and enabling the first air outlet 221 and the second air outlet 251 in different circumferential directions to obtain the same amount of hot air, thereby keeping the air outlet intensity of each first air outlet 221 consistent, and keeping the air outlet intensity of each second air outlet 251 consistent.

[0138] In some alternative embodiments, such as Figure 3 and Figure 4 As shown, the main body 1 also includes a sealing ring 14, which is disposed between the second base plate 11 and the rear back plate 12 and is used to seal the gap between the second base plate 11 and the rear back plate 12. The second communication port 111 and the air outlet 31 are both located on the radial inner side of the sealing ring 14.

[0139] With this configuration, the sealing ring 14 can precisely seal the assembly gap between the second base plate 11 and the rear back plate 12, preventing hot air entering the second space 8 from the air outlet 31 of the drying air duct 3 from leaking through the gap. This effectively prevents heat waste, temperature drop, and reduced drying efficiency caused by hot air loss, while also preventing leaked hot air from contacting other internal components and causing component aging problems.

[0140] For subject 1, in some other alternative embodiments, such as Figure 9 and Figure 10 As shown, the main body 1 includes a back panel 12, a fan cover 13, and a sealing ring 14. The back panel 12 is located on the side of the first bottom plate 22 opposite to the cylinder sidewall 23. The fan cover 13 is connected to the back panel 12 and is located on the side of the back panel 12 opposite to the first bottom plate 22. The fan cover 13 and the back panel 12 together form a drying air duct 3. Figure 8 As shown, the air outlet 31 is located on the rear panel 12.

[0141] The sealing ring 14 is disposed between the back plate 12 and the cylinder side wall 23 and is used to seal the gap between the back plate 12 and the cylinder side wall 23. The air outlet 31, the first air outlet 221 and the first connecting port 222 are all disposed on the radial inner side of the sealing ring 14.

[0142] With this configuration, since the second base plate 11 is not provided, the structural composition of the main body 1 can be simplified, which in turn facilitates the processing, manufacturing and assembly of the main body 1.

[0143] In some optional embodiments, the main body 1 includes an outer shell (not shown in the figure), which can form a machine compartment. The inner drum 2 and other components are housed in the machine compartment, and the outer shell is provided with an openable door. Users can put clothes into the drying chamber 21 of the inner drum 2 by opening the door, so that the dryer can dry the clothes. Alternatively, users can also take out the dried clothes through the door.

[0144] This design isolates the core components, such as the inner drum 2, from the external environment, protecting them and extending the dryer's lifespan. Additionally, the door facilitates easy loading and unloading of clothes.

[0145] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although 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.
