Description

Technical Field

[0001] This application relates to the field of electrical 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 consume a lot of energy 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 with high drying efficiency and low energy consumption.

[0006] To address the aforementioned technical problems, 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 arranged opposite to each other. The base plate is provided with a connecting port and multiple first air outlets. The first air outlets are configured to blow hot air in the drying air duct into the drying chamber through the first air outlets.

[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 provided on the side wall of the cylinder and located inside the drying chamber. The lifting ribs include:

[0015] The extension body extends along the extension direction of the cylinder sidewall;

[0016] The movable part is detachably set on the extension body. The movable part and the extension body together form a connecting cavity with an opening. The opening and the connecting port of the connecting cavity are connected to each other. 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.

[0017] The active section is equipped with a second air outlet, which is connected to the connecting cavity. The second air outlet is configured to blow hot air from the connecting cavity into the drying cavity through the second air outlet.

[0018] This design allows hot air to be blown into the drying chamber through both the first and second air outlets. The hot air entering the drying drum from the first and second air outlets can dry the clothes from different directions, improving the dryer's drying efficiency and effect. Furthermore, if lint or other impurities enter the connecting chamber during the drying process, the user can detach the movable part from the extension body to open the connecting chamber, thereby cleaning the accumulated lint and debris from the second air outlet, further ensuring the dryer's drying efficiency and effect.

[0019] Optionally, the movable part is slidably connected to the extension body and is detachably mounted on the extension body; the movable part slides along the extension direction of the cylinder sidewall.

[0020] This design facilitates easy installation and removal of the movable part from the extension body. It also allows users to more easily clean lint and debris clogging the second air outlet or accumulating in the connecting cavity, improving the user experience.

[0021] Optionally, the extension body has a first mounting surface facing the movable part. The first mounting surface extends along the extension direction of the cylinder sidewall, and a sliding groove structure is provided on the first mounting surface. The movable part is slidably mounted on the sliding groove structure, and the sliding direction of the movable part is consistent with the rotation axis direction of the inner cylinder.

[0022] This design allows the movable part to be securely mounted on the extension body, and also makes it easy for the user to remove the movable part from the extension body.

[0023] Optionally, the slide structure includes a plurality of slide rail portions disposed on the first assembly surface, each slide rail portion having a slide groove extending along the extension direction of the cylinder sidewall; the plurality of slide rail portions are arranged in at least two rows, the slide groove opening direction of each row of slide rail portions is consistent, and the at least two rows of slide rail portions have two different slide groove opening directions.

[0024] The movable part has multiple sliders, which are arranged in at least two columns, and each column of sliders is slidably assembled in the corresponding column of slide rails.

[0025] With this configuration, the movable part can slide relative to the extended body to assemble the slider from the groove opening into the slide rail part, and different sliders can be positioned in different slide rail parts in two opposite directions, so that the movable part is more securely assembled onto the extended body.

[0026] Optionally, the slide rail section includes a plurality of first slide rail sections and a plurality of second slide rail sections, wherein the first slide rail sections are arranged in a row and the second slide rail sections are arranged in a row;

[0027] The grooves of the first slide rail and the second slide rail both extend in a direction parallel to the first mounting surface, and the groove openings of the first slide rail and the second slide rail are opposite in direction.

[0028] This design allows the first and second slide rails to position the sliders in opposite directions along a direction perpendicular to the first mounting surface, thus securing the movable part to the extension body and preventing it from loosening during the drying process. Furthermore, the sliders can slide relative to either the first or second slide rail along the extension direction of the first mounting surface to disengage from either slide rail, allowing users to easily remove the movable part from the extension body and clean lint, improving the user experience.

[0029] Optionally, the slide rail has a first extension and a second extension. The first extension is connected to the first mounting surface and extends away from the first mounting surface. The first end of the second extension is connected to the first extension and the second end of the second extension extends out in a direction parallel to the first mounting surface and away from the first extension, so as to form a slide groove together with the first extension.

[0030] With this configuration, when the slider is assembled in the groove, the first extension section can abut against the slider to prevent the slider from sliding in a direction perpendicular to the extension direction of the first assembly surface; the second extension section can abut against the slider to prevent the slider from moving away from the first assembly surface. The first and second extension sections can position the slider relatively stably in the groove, which helps to prevent the slider from wobbling in the groove and allows the movable part to be assembled relatively stably on the extension body.

[0031] Optionally, the slide rails of different columns are arranged alternately in the direction of extension of the cylinder sidewall; the positions of the multiple sliders correspond one-to-one with the positions of the slide rails.

[0032] This design allows the slider to be easily assembled into the grooves of the first and second slide rails, and to be easily detached from the first and second slide rails. This facilitates the user's assembly of the movable part onto the extension body, and also makes it easier for the user to remove the movable part from the extension body and clean up lint, thus improving the user experience.

[0033] Optionally, the extension body also has a second mounting surface connected to one side of the first mounting surface, and when the movable part is slidably mounted in the slide groove structure, the movable part abuts against the second mounting surface.

[0034] The second mounting surface has a first snap-fit ​​portion, the movable portion has a second snap-fit ​​portion, and the first snap-fit ​​portion and the second snap-fit ​​portion snap-fit ​​each other to fix the movable portion and the extension body relative to each other in a direction intersecting the sliding direction of the movable portion; and / or, the movable portion and the extension body are fixed relative to each other in a direction intersecting the sliding direction of the movable portion by fasteners.

[0035] This design prevents the movable part from wobbling relative to the extension body in the direction intersecting with the sliding direction of the movable part, and prevents the movable part from loosening during the drying process of clothes in the dryer, so that the movable part can be more firmly attached to the extension body.

[0036] Optionally, a guide groove is provided on the first assembly surface, and the extending direction of the guide groove is consistent with the sliding direction of the movable part;

[0037] The movable part is provided with a guide protrusion that matches the guide groove. When the movable part is slidably installed relative to the extended body, the guide protrusion is located in the guide groove and slides along the guide groove.

[0038] This design allows the guide groove and guide protrusion to guide the user in sliding the movable part during assembly and to guide the user in removing the movable part. Furthermore, the guide groove and guide protrusion can also be used to position the movable part and the extension body, facilitating the user's installation of the movable part onto the extension body and improving the user experience.

[0039] Optionally, the positions of the connecting port and the lifting rib are corresponding and relative 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.

[0040] The openings of the connecting cavity and the connecting port are positioned opposite each other and are interconnected.

[0041] This design allows more hot air to enter the connecting cavity and then enter the drying cavity through the second air outlet, increasing the air volume of the second air outlet and improving the drying efficiency and effect of the dryer. Attached Figure Description

[0061] 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.

[0062] 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.

[0063] Please refer to Figure 1 , Figure 2 as well as Figure 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.

[0064] 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.

[0065] 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, allowing the clothes to be lifted to a certain height before being released, 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.

[0066] The lifting rib 140 includes an extension body 150 and a movable part 160 disposed on the extension body 150. The extension body 150 extends along the extension direction of the cylinder side wall 130. The movable part 160 and the extension body 150 together form a connecting cavity 170 with an opening 171. The bottom plate 120 is provided with a connecting port 122 that communicates with the drying air duct 200. The opening 171 and the connecting port 122 are interconnected. Thus, the connecting cavity 170 can be used to blow hot air in the drying air duct 200 into the connecting cavity 170 in sequence through the connecting port 122 and the opening 171.

[0067] The movable part 160 is provided with a second air outlet 161, which is connected to the connecting cavity 170. The second air outlet 161 is used to blow hot air in the connecting cavity 170 into the drying cavity 110 through the second air outlet 161.

[0068] With this configuration, hot air can be blown onto the clothes in the drying chamber 110 through the first air outlet 121 and the second air outlet 161 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 161 can dry the clothes from different directions, thereby improving the drying efficiency and drying effect of the dryer 10.

[0069] Meanwhile, during the drying process of clothes in the dryer 10, the hot air flow may carry some lint and other impurities. When the hot air is blown out through the connecting cavity 170 and the second air outlet 161, the lint may block the second air outlet 161, resulting in a reduction in the drying efficiency and drying effect of the dryer 10. For example, as hot air enters the drying cavity 110 through the drying duct 200, some of the lint it carries may enter the drying duct 200, and then be blown into the connecting cavity 170 through the connecting port 122 and the opening 171 along with the hot air in the drying duct 200, eventually blocking the second air outlet 161.

[0070] To facilitate the cleaning of lint clogging the second air outlet 161 or accumulating in the connecting cavity 170, the movable part 160 is detachably mounted on the extension body 150. This configuration allows the user to remove the movable part 160 from the extension body 150 to clean the lint from the second air outlet 161. Simultaneously, with the removal of the movable part 160, the connecting cavity 170 is opened, allowing for the cleaning of lint within the connecting cavity, thus ensuring the drying efficiency and effect of the dryer 10.

[0071] 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.

[0072] 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.

[0073] Please refer to Figure 1 and Figure 2The main body of the dryer 10 may include a casing (not shown in the figure), which can form a compartment in which 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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 also 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 also be collinear with the central axis of the cylinder side wall 130.

[0078] 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.

[0079] The dryer 10 may also 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.

[0080] 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.

[0081] In one embodiment, the dryer 10 may further 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.

[0082] Please refer to Figure 2 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.

[0083] 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 air duct 200. The dryer 10 may further 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 and form another portion of the drying air duct 200. An air duct opening is provided on the support plate 400, which is used to connect the drying air 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 is in close contact with the inner drum 100. Correspondingly, the bottom plate 120 is disposed 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 seal 600 can be in close contact with either the base plate 120 or the cylinder sidewall 130.

[0084] 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.

[0085] 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.

[0086] Please refer to Figure 3 The extension body 150 of the lifting rib 140 is connected to the cylinder side wall 130 and extends along the extension direction of the cylinder side wall 130. In the extension direction of the extension body 150, one end of the extension body 150 is connected to the bottom plate 120, and the other end of the extension body 150 faces the opening of the drying chamber 110. There may be a gap between the end of the extension body 150 facing the opening of the drying chamber 110 and the opening of the drying chamber 110; that is, the extension body 150 may be spaced apart from the opening of the drying chamber 110.

[0087] Please refer to 4 and Figure 5 The opening 171 of the connecting cavity 170 is provided in the extension body 150 and is located at one end of the extension body 150 near the bottom plate 120. The extension body 150 is connected to the bottom plate 120 to enclose the opening 171, while the extension body 150 covers the connecting port 122, so that the connecting port 122 is connected to the opening 171.

[0088] Please refer to Figure 6 and Figure 7 The extension body 150 also has an enclosing cavity 151 and an enclosing opening 152 that are interconnected, with the enclosing cavity 151 communicating between the opening 171 and the enclosing opening 152. The enclosing opening 152, the enclosing cavity 151, and the opening 171 can be arranged sequentially in the extension direction of the extension body 150, and the enclosing opening 152 can be disposed facing the opening of the drying chamber 110. The enclosing cavity 151 includes at least a portion of the communicating cavity 170, that is, when the movable part 160 is installed on the extension body 150, the enclosing cavity 151 constitutes a part of the communicating cavity 170.

[0089] In one embodiment, the connecting port 122 and the lifting rib 140 are positioned correspondingly and opposite to each other, and the opening 171 of the connecting cavity 170 is opposite to and communicates with the connecting port 122. Here, "opposite to each other" can be understood as the connecting port 122, the lifting rib 140, and the opening 171 being arranged sequentially in the extending direction of the cylinder sidewall 130. On a plane parallel to the bottom plate 120, the projection of the connecting cavity 170 can overlap with the projection of the opening 171, and the projection of the connecting port 122 can be located within the projections of the connecting cavity 170 and the opening 171, or the projection of the connecting port 122 can also overlap with the projections of the connecting cavity 170 and the opening 171.

[0090] Therefore, the hot air in the drying duct 200 can pass through the connecting port 122 and the opening 171 in a straight line and enter the connecting cavity 170. The flow of hot air is relatively smooth, which is conducive to improving the efficiency of the dryer 10.

[0091] Alternatively, "relative setting" can also be understood as the connection port 122 being closer to the connection cavity 170 than the first air outlet 121 in the direction perpendicular to the central axis of the inner cylinder 100.

[0092] In one embodiment, the cross-sectional area of ​​the connecting port 122 is larger than the cross-sectional area of ​​the single first air outlet 210. This arrangement allows more hot air to enter the connecting cavity 170 and then enter the drying cavity 110 via the second air outlet 161, increasing the airflow of the second air outlet 161 and improving the drying efficiency and drying effect of the dryer 10.

[0093] Please continue to refer to Figure 6 and Figure 7The movable part 160 is installed on the side of the extension body 150 near the central axis of the inner cylinder 100, and the extension direction of the movable part 160 can be parallel or approximately parallel to the extension direction of the extension body 150. The movable part 160 has an enclosing groove 162, which includes at least a portion of a connecting cavity 170. A second air outlet 161 penetrates the movable part 160 and communicates with the enclosing groove 162. When the movable part 160 is installed on the extension body 150, the movable part 160 covers the enclosing opening 152 and connects the enclosing groove 162 and the enclosing cavity 151 to jointly form the connecting cavity 170. That is, the movable part 160 and the extension body 150 together form the connecting cavity 170. Thus, hot air in the connecting cavity 170 can sequentially enter the drying chamber 110 through the drying air duct 200, the connecting opening 122, the opening 171, the connecting cavity 170, and the second air outlet 161. Within the connecting cavity 170, hot air can flow from the opening 171 through the enclosing cavity 151, the enclosing opening 152, and the enclosing groove 162 to the second air outlet 161.

[0094] In the above example, multiple second air outlets 161 can be provided, and each second air outlet 161 can be arranged in at least one column along the extension direction of the movable part 160. For example, each second air outlet 161 can be arranged in two columns, or each second air outlet 161 can be arranged in one column, three columns or more. Among them, the second air outlets 161 in different columns can be alternately arranged in the extension direction of the movable part 160.

[0095] With this configuration, each of the second air outlets 161 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.

[0096] The orientation of the second air outlet 161 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 161. Thus, the hot air blown out of the first air outlet 121 and the hot air blown out of the second air outlet 161 can dry clothes from different directions.

[0097] In one example, the second air outlet 161 may be positioned facing the central axis of the drying cylinder, and the orientation of the second air outlet 161 may be perpendicular or approximately perpendicular to the central axis of the drying cylinder. Correspondingly, the orientation of the second air outlet 161 may be perpendicular or approximately perpendicular to the orientation of the first air outlet 121.

[0098] In other examples, the second air outlet 161 may also be positioned not to face the central axis of the drying cylinder.

[0099] In the above example, different second air outlets 161 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.

[0100] In one embodiment, the movable part 160 can be slidably connected to the extension body 150 for mounting onto or detaching from the extension body 150. In one example, the movable part 160 can slide relative to the extension body 150 along the extending direction of the cylinder sidewall 130, that is, the sliding direction of the movable part 160 can be aligned with the direction of the rotation axis of the inner cylinder 100. The movable part 160 can slide along the extending direction of the cylinder sidewall 130 toward the enclosure opening 152 of the extension body 150 for mounting onto the extension body 150, or the movable part 160 can slide along the extending direction of the cylinder sidewall 130 toward the opening of the drying chamber 110 for detachment from the extension body 150. In other examples, the movable part 160 can also slide radially relative to the extension body 150 along the cylinder sidewall 130.

[0101] This design facilitates the user's installation of the movable part 160 onto the extension body 150, and also facilitates the user's removal of the movable part 160 from the extension body 150. It allows the user to more easily clean lint clogging the second air outlet 161 or accumulating in the connecting cavity 170, ensuring the drying effect of the dryer 10 and improving the user experience.

[0102] In one embodiment, such as Figure 6 and Figure 7 As shown, the extension body 150 has a first mounting surface 153 facing the central axis of the inner cylinder 100. The first mounting surface 153 is parallel to the extension direction of the cylinder sidewall 130 and extends along the extension direction of the cylinder sidewall 130. The connecting cavity 170 is located on the side of the first mounting surface 153 near the central axis of the inner cylinder 100. The first mounting surface 153 can be used to form the connecting cavity 170 and includes at least a portion of the cavity wall of the connecting cavity 170.

[0103] The movable part 160 can fit against and slide on the first mounting surface 153. In an example where the movable part 160 slides along the extension direction of the cylinder sidewall 130, the sliding direction of the movable part 160 is parallel to the extension direction of the first mounting surface 153, and the movable part 160 can slide along the extension direction of the first mounting surface 153. When the movable part 160 is mounted on the extension body 150, the movable part 160 covers the first mounting surface 153; after the movable part 160 is removed from the extension body 150, the first mounting surface 153 is exposed on the extension body 150.

[0104] In one example, please refer to Figure 7A guide groove 1531 may be provided on the first mounting surface 153. The extending direction of the guide groove 1531 is consistent with the sliding direction of the movable part 160, that is, the guide groove 1531 can extend along the extending direction of the first mounting surface 153. The movable part 160 is provided with a guide protrusion 163 that matches the guide groove 1531. The guide protrusion 163 can extend into the guide groove 1531. When the movable part 160 slides relative to the extension body 150 to be installed on or removed from the extension body 150, the guide protrusion 163 slides along the guide groove 1531 with the movable part 160 within the guide groove 1531.

[0105] Therefore, the guide groove 1531 and guide protrusion 163 can be used to guide the user to slide and assemble the movable part 160, and can also be used to guide the user to remove the movable part 160. Furthermore, the guide groove 1531 and guide protrusion 163 can also be used to position the movable part 160 and the extension body 150, facilitating the user's installation of the movable part 160 onto the extension body 150, thus improving the user experience.

[0106] The guide groove 1531 and guide protrusion 163 can be provided in multiple ways, with each guide protrusion 163 corresponding to a different guide groove 1531. For example, there can be two guide grooves 1531, which are positioned opposite each other on both sides of the first mounting surface 153 in a direction perpendicular to the extending direction of the first mounting surface 153. Correspondingly, there can also be two guide protrusions 163, which are positioned opposite each other on both sides of the movable part 160.

[0107] The extension body 150 also has a second mounting surface 154 connected to one side of the first mounting surface 153. For example, the second mounting surface 154 may be located on the side of the first mounting surface 153 near the base plate 120. When the movable part 160 is mounted on the extension body 150, the end of the movable part 160 near the base plate 120 abuts against the second mounting surface 154. Thus, the first mounting surface 153 and the second mounting surface 154 can be used to position the movable part 160 on the extension body 150. The enclosure opening 152 may be provided on the second mounting surface 154.

[0108] Please refer to Figure 5 and Figure 6 In one embodiment, a groove structure 155 is provided on the first mounting surface 153, and the movable part 160 is movably mounted on the groove structure 155. For example, when the movable part 160 slides along the extension direction of the first mounting surface 153 and abuts against the second mounting surface 154, the movable part 160 is mounted on the groove structure 155; when the movable part 160 slides along the extension direction of the first mounting surface 153 away from the second mounting surface 154, the movable part 160 leaves the groove structure 155.

[0109] This design allows the movable part 160 to be securely mounted on the extension body 150, and also makes it easy for the user to remove the movable part 160 from the extension body 150.

[0110] Please refer to Figure 6 and Figure 7 In one embodiment, the slide structure 155 includes slide rail portions 156 disposed on the first mounting surface 153. Multiple slide rail portions 156 are provided and arranged in at least two columns. The multiple slide rail portions 156 in each column are spaced apart in the extending direction of the first mounting surface 153. The movable part 160 has multiple sliders 164 corresponding to the slide rail portions 156. The multiple sliders 164 are also arranged in at least two columns, and each column of sliders 164 is slidably fitted into its corresponding column of slide rail portions 156 to assemble the movable part 160 onto the extension body 150.

[0111] The slide rail portion 156 has a groove 157, and the slider 164 can be engaged within the groove 157 to be fitted into the slide rail portion 156. In the extending direction of the first mounting surface 153, the groove openings of the grooves 157 in each row of slide rail portions 156 are aligned. This configuration allows the movable portion 160 to slide relative to the extending body 150 to fit the slider 164 from the groove opening into the slide rail portion 156.

[0112] Furthermore, in the direction perpendicular to the extension direction of the first mounting surface 153, at least two rows of slide rails 156 also have two different groove opening directions 157. With this configuration, different sliders 164 can be positioned in different slide rails 156 in two opposite directions, so that the movable part 160 is more securely mounted on the extension body 150.

[0113] In some implementation methods, please combine Figure 8 and Figure 9The slide rail portion 156 may have a first extension 1561 and a second extension 1562, both extending along the extension direction of the first mounting surface 153. The first extension 1561 is disposed on the first mounting surface 153 and extends in a direction away from the first mounting surface 153. The second extension 1562 is spaced apart from the first mounting surface 153. A first end of the second extension 1562 is connected to the side of the first extension 1561 away from the first mounting surface 153, and a second end of the second extension 1562 extends in a direction parallel to the first mounting surface 153 and perpendicular to its extension direction. The second end of the second extension 1562 is further away from the first extension 1561 than its first end, and the distance between the first end of the second extension 1562 and the first mounting surface 153 may be equal to the distance between the second end of the second extension 1562 and the first mounting surface 153. Thus, the second extension 1562 and the first extension 1561 together form the chute 157.

[0114] When the slider 164 is assembled in the groove 157, the first extension 1561 abuts against the slider 164 to prevent the slider 164 from sliding in a direction perpendicular to the extension direction of the first mounting surface 153; the second extension 1562 abuts against the slider 164 to prevent the slider 164 from moving away from the first mounting surface 153. This configuration allows the first extension 1561 and the second extension 1562 to stably position the slider 164 within the groove 157, preventing the slider 164 from wobbling within the groove 157 and ensuring that the movable part 160 is stably assembled onto the extension body 150.

[0115] In some implementations, the slide rail section 156 may have two rows, with the two rows of slide rail sections 156 positioned opposite each other on both sides of the first mounting surface 153 in a direction perpendicular to the extending direction of the first mounting surface 153. Correspondingly, the slider 164 may also have two rows, with the two rows of sliders 164 respectively corresponding to the two rows of slide rail sections 156, and may be positioned opposite each other on both sides of the movable part 160. In other examples, the slide rail section 156 may also have three or more rows.

[0116] For example, the slide rail portion 156 may include a plurality of first slide rail portions 156a and a plurality of second slide rail portions 156b, with the first slide rail portions 156a arranged in one column and the second slide rail portions 156b arranged in another column. Correspondingly, a plurality of sliders 164 are arranged in at least two columns, with one column of sliders 164 corresponding to the first slide rail portion 156a and the other column corresponding to the second slide rail portion 156b.

[0117] In the extending direction of the first mounting surface 153, the groove opening direction of the first slide rail portion 156a is the same as that of the second slide rail portion 156b, and both the groove 157 of the first slide rail portion 156a and the groove 157 of the second slide rail portion 156b extend in a direction parallel to the first mounting surface 153. Correspondingly, the first extension segment 1561 of the first slide rail portion 156a and the first extension segment 1561 of the second slide rail portion 156b are parallel to each other.

[0118] In the direction perpendicular to the extension direction of the first mounting surface 153, the groove 157 opening direction of the first slide rail portion 156a is opposite to the groove 157 opening direction of the second slide rail portion 156b.

[0119] For example, the groove 157 opening of the first slide rail portion 156a can face the side of the first slide rail portion 156a away from the second slide rail portion 156b, and the groove 157 opening of the second slide rail portion 156b can face the side of the second slide rail portion 156b away from the first slide rail portion 156a. Correspondingly, the second extension 1562 of the first slide rail portion 156a is located on the side of its first extension 1561 away from the second slide rail portion 156b, and the second extension 1562 of the second slide rail portion 156b is located on the side of its first extension 1561 away from the first slide rail portion 156a.

[0120] Alternatively, the groove 157 opening of the first slide rail portion 156a can face the second slide rail portion 156b, and the groove 157 opening of the second slide rail portion 156b can face the first slide rail portion 156a, and be disposed opposite to the groove 157 opening of the first slide rail portion 156a. Correspondingly, the second extension 1562 of the first slide rail portion 156a is located on the side of its first extension 1561 near the second slide rail portion 156b, and the second extension 1562 of the second slide rail portion 156b is located on the side of its first extension 1561 near the first slide rail portion 156a.

[0121] With this configuration, in the direction perpendicular to the extension direction of the first mounting surface 153, the first slide rail portion 156a and the second slide rail portion 156b can position the slider 164 in two opposite directions to securely position the movable part 160 on the extension body 150, preventing the movable part 160 from loosening during the drying process of clothes in the dryer 10. Furthermore, the slider 164 can slide relative to the first slide rail portion 156a or the second slide rail portion 156b along the extension direction of the first mounting surface 153 to disengage from either the first slide rail portion 156a or the second slide rail portion 156b, allowing the user to easily remove the movable part 160 from the extension body 150 and clean lint, thus improving the user experience.

[0122] In the above example, the slide rails 156 in different columns are arranged alternately in the extension direction of the cylinder sidewall 130, that is, in the extension direction of the first mounting surface 153, and the positions of the multiple sliders 164 and the positions of each slide rail 156 are set one-to-one.

[0123] For example, the first slide rail portion 156a and the second slide rail portion 156b can be arranged alternately in the extending direction of the first mounting surface 153. In the extending direction of the first mounting surface 153, the first slide rail portion 156a and the second slide rail portion 156b are arranged sequentially, and each first slide rail portion 156a can be located between two adjacent second slide rail portions 156b.

[0124] This design allows the slider 164 to be easily assembled into the groove 157 of the first slide rail 156a and the second slide rail 156b, and to be easily detached from the first slide rail 156a and the second slide rail 156b. This facilitates the user's assembly of the movable part 160 onto the extension body 150, and also makes it easier for the user to remove the movable part 160 from the extension body 150 and clean up lint, thus improving the user experience.

[0125] In one embodiment, please refer back to Figure 7 The second mounting surface 154 of the extension body 150 has a first engaging portion 1541, and the movable portion 160 has a second engaging portion 165 that is adapted to the first engaging portion 1541. When the movable portion 160 is slidably mounted on the extension body 150, the second engaging portion 165 engages with the first engaging portion 1541. In a direction intersecting with the sliding direction of the movable portion 160, the first engaging portion 1541 and the second engaging portion 165 engage to position the movable portion 160, thereby fixing the movable portion 160 relatively to the extension body 150.

[0126] This design prevents the movable part 160 from wobbling relative to the extension body 150 in the direction intersecting with the sliding direction of the movable part 160, and prevents the movable part 160 from loosening during the drying process of clothes in the dryer 10, so that the movable part 160 can be more securely mounted on the extension body 150.

[0127] In one embodiment, the movable part 160 and the extension body 150 can be relatively fixed to each other by fasteners in a direction intersecting the sliding direction of the movable part 160. For example, the movable part 160 may be provided with a fixing hole 166, and the extension body 150 may be provided with a fixing groove 158 opposite to the fixing hole 166. The fastener can pass through the fixing hole 166 and connect to the groove wall of the fixing groove 158 to fix the movable part 160 to the extension body 150. The fastener may include screws, bolts, or threaded rods.

[0128] This design prevents the movable part 160 from wobbling relative to the extension body 150 in the direction intersecting with the sliding direction of the movable part 160, and prevents the movable part 160 from loosening during the drying process of clothes in the dryer 10, so that the movable part 160 can be more securely mounted on the extension body 150.

[0129] In the above example, the first snap-fit ​​portion 1541 and the second snap-fit ​​portion 165 are located at one end of the movable portion 160 near the base plate 120, and the fastener can be located at the other end of the movable portion 160 near the opening of the drying chamber 110 relative to the first snap-fit ​​portion 1541 and the second snap-fit ​​portion 165.

[0130] In one embodiment, 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.

[0131] 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 161, thereby improving the drying efficiency and drying effect of the dryer 10.

[0132] 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.
