In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0055] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0056] The structure of a traditional clothes dryer includes a clothing processing drum, a support plate and an air duct shell. The clothing processing drum defines a clothing processing chamber. A ventilation chamber is defined between the air duct shell and the support plate. An air outlet area connected to the ventilation chamber is formed on the support plate. An air inlet area connected to the clothing processing chamber is formed on the rear wall of the clothing processing drum. The air outlet area and the air inlet area are arranged correspondingly, and a second flow channel is defined between the two. The air flow passes through the ventilation chamber, the air outlet area, the second flow channel and the air inlet area in sequence and enters the clothing processing chamber. The clothing processing drum is fixed to the rear plate by a bearing.

[0057] In the prior art, the capacity of the clothing processing drum is limited by the structure and cannot process more and larger clothes at the same time, which affects the user experience. In addition, the airflow passes through the plate twice in the process of passing through the air outlet area opened on the support component and the air inlet area opened on the bottom wall of the clothing processing drum in sequence. The flow resistance in the process is large, and the air loss is large. In addition, the opening of the air passing structure such as the air outlet area and the air inlet area increases the production cost of the dryer.

[0058] To this end, the embodiment of the utility model designs a dryer in which at least a portion of the portion of the support plate opposite to the clothing processing drum is simultaneously formed as a portion of the rear wall of the clothing processing drum, and this portion simultaneously defines a clothing processing chamber together with the clothing processing drum, and defines a ventilation chamber between the portion and the air duct shell. That is to say, the embodiment of the utility model integrates the air outlet area opened on the support plate in the prior art with the air inlet area opened on the clothing processing drum in the prior art, simplifies the structure of the dryer, reduces the production cost of the dryer, and in the process of conveying the air flow from the ventilation chamber to the clothing processing chamber, the air flow only needs to pass through the plate once, thereby reducing the flow resistance and reducing the air volume loss. Compared with the prior art, the rear wall of the clothing processing drum of the dryer in the embodiment of the utility model is rearwardly placed, which increases the volume of the clothing processing chamber, and the dryer can process more and larger clothes at the same time, thereby improving the user experience.

[0059] Reference below Figure 1-Figure 13 A clothes dryer 1000 according to an embodiment of the present invention is described.

[0060] The clothes dryer 1000 according to the embodiment of the present invention may include: an air duct housing 13 , a support assembly 12 and a clothes processing drum 2 .

[0061] Among them, the air duct shell 13 defines a ventilation cavity 101 with an opening on one side, and the support assembly 12 is connected to the air duct shell 13 to cover the opening on one side of the ventilation cavity 101. That is to say, the air duct shell 13 and the support assembly 12 together constitute the air duct 401 shell assembly 1, and together define the ventilation cavity 101.

[0062] The clothing processing drum 2 is arranged on the side of the support component 12 facing away from the air duct shell 13. In other words, the air duct shell 13 and the clothing processing drum 2 are respectively arranged on both sides of the support component 12. The clothing processing drum 2 defines a clothing processing cavity 201 having a clothing access port at one end and a ventilation port 202 at the other end. The edge of the ventilation port 202 is movably cooperated with the support component 12 to ensure that the clothing processing drum 2 can rotate relative to the air duct shell assembly 1 401, so as to realize the flipping of clothing during the drying process and achieve a more uniform drying effect.

[0063] The support component 12 and the clothing processing drum 2 jointly define the clothing processing chamber 201, that is, the portion of the support component 12 opposite to the vent 202 and the clothing processing drum 2 jointly define the clothing processing chamber 201, the portion of the support component 12 opposite to the vent 202 and the air duct shell 13 on the other side define a portion of the ventilation chamber 101, and the portion of the support component 12 opposite to the vent 202 simultaneously constitutes the wall surface of the clothing processing chamber 201 and the wall surface of the ventilation chamber 101, wherein the support component 12 has an air inlet portion 7, and the air inlet portion 7 can be provided on the structure of the portion of the support component 12 opposite to the vent 202, and the air inlet portion 7 connects the clothing processing chamber 201 and the ventilation chamber 101.

[0064] That is to say, the airflow in the ventilation cavity 101 can directly enter the clothing processing cavity 201 through the air inlet portion 7. On the one hand, the structure of the dryer 1000 is simplified and the production cost of the dryer 1000 is reduced. On the other hand, during the process of the airflow being transported from the ventilation cavity 101 to the clothing processing cavity 201, the airflow only needs to pass through the air inlet portion 7, and the flow resistance is smaller, thereby reducing the air volume loss during the airflow transportation process. In addition, the rear wall of the clothing processing drum 2 is placed at the rear, and the volume of the clothing processing cavity 201 can be expanded, thereby increasing the depth of the clothing processing drum 2 and the volume of the clothing processing cavity 201. The dryer 1000 can process more and larger clothes at the same time, thereby improving the user experience.

[0065] According to the dryer 1000 of the embodiment of the utility model, the dryer 1000 has low production cost and small air volume loss during air flow delivery. The volume of the clothes processing chamber 201 is larger, and more and larger clothes can be processed at the same time, thereby improving the user experience.

[0066] like Figure 2 , Figure 4 , Figure 6 , Fig.10 and Fig.12 As shown, the support assembly 12 has a first extension portion 1221 extending in a direction away from the clothes treatment drum 2. The first extension portion 1221 extends from a side opening of the air duct shell 13 into the ventilation cavity 101. The first extension portion 1221 defines an air inlet cavity connected to the clothes treatment cavity 201. The air inlet portion 7 is provided on the first extension portion 1221. By designing the first extension portion 1221 on the support assembly 12, the capacity of the clothes treatment cavity 201 can be further increased, and the clothes dryer 1000 can process more and larger clothes at the same time. The air inlet portion 7 connects the air inlet cavity and the ventilation cavity 101, that is, the intake air flow in the ventilation cavity 101 enters the air inlet cavity through the air inlet portion 7, and enters the inner cavity of the clothes treatment drum 2 through the air inlet cavity. The clothes treatment cavity 201 includes the inner cavity of the clothes treatment drum 2 and the air inlet cavity.

[0067] The first extension portion 1221 is provided with an air inlet portion 7 which is connected with the clothing processing chamber 201 and the ventilation chamber 101. The air flow can enter the clothing processing chamber 201 through the air inlet portion 7 provided on the first extension portion 1221. Since the first extension portion 1221 is protruded into the ventilation chamber 101, the air inlet portion 7 is arranged inside the ventilation chamber 101, so that the air inlet portion 7 can better receive the air flow, reduce the resistance of the air flow in the process of flowing into the clothing processing chamber 201, and increase the air volume in the clothing processing chamber 201.

[0068] Reference Figure 2 , Figure 4 , Figure 6 , Fig.10 and Fig.12 The support assembly 12 includes: a support plate 121 and an air inlet cover 122. The support plate 121 is arranged between the clothing processing drum 2 and the air duct shell 13 to provide an installation position for the air duct shell 13 and the clothing processing drum 2. The air duct shell 13 is fixedly arranged inside the dryer 1000 through the support plate 121, and the clothing processing drum 2 is supported on the support plate 121.

[0069] The support plate 121 has a through opening 1211. Specifically, the support plate 121 has a through opening 1211 at a position corresponding to the vent 202 of the clothing processing drum 2. The airflow in the ventilation cavity 101 can flow out of the ventilation cavity 101 through the through opening 1211, and the airflow can enter the clothing processing cavity 201 through the vent 202. The air inlet hood 122 is arranged between the ventilation cavity 101 and the clothing processing cavity 201, and the air inlet hood 122 covers the through opening 1211 and the vent 202 at the same time. One side surface of the air inlet hood 122, the air duct shell 13 and the support plate 121 jointly define the ventilation cavity 101, and the other side surface of the air inlet hood 122, the clothing processing drum 2 jointly define the clothing processing cavity 201, and the airflow can pass through the air inlet hood 122. The airflow in the ventilation cavity 101 can directly enter the clothing processing cavity 201 through the air inlet part 7 provided on the air inlet hood 122.

[0070] At least a portion of the air inlet cover 122 extends away from the clothing processing drum 2 to form a first extension portion 1221. The first extension portion 1221 formed by the air inlet cover 122 extending away from the clothing processing drum 2 is not subject to structural restrictions and can further increase the volume of the clothing processing chamber 201.

[0071] In some embodiments, the support plate 121 and the air inlet cover 122 are integrally formed to simplify the production steps of the dryer 1000 and ensure the sealing of the connection between the air inlet cover 122 and the support plate 121.

[0072] In other embodiments, the support plate 121 and the air inlet cover 122 are separately molded and mechanically connected to fix the air inlet cover 122 to the support plate 121 structure. Since the air inlet cover 122 has a complex structure, it is not conducive to stamping and forming it as one piece with the support plate 121. Therefore, by stamping the support plate 121 and the air inlet cover 122 separately and then fixing them together, the production difficulty of the dryer 1000 can be reduced and the production cost of the dryer 1000 can be reduced.

[0073] Reference Figure 10-13 The air inlet hood 122 has an annular limiting groove 1222 on the side facing away from the clothing processing drum 2, and the edge of the through opening 1211 has a flange structure 1212 extending into the annular limiting groove 1222. The flange structure 1212 cooperates with the annular limiting groove 1222. On the one hand, the installation position of the air inlet hood 122 can be positioned during the process of installing the air inlet hood 122 on the support plate 121 to ensure the accuracy of the installation position of the air inlet hood 122. On the other hand, the flange structure 1212 can increase the matching area between the air inlet hood 122 and the support plate 121 to ensure the stability of the connection between the air inlet hood 122 and the support plate 121.

[0074] Reference Figure 2The first extension portion 1221 includes an end wall arranged opposite to the clothing access opening and a peripheral wall surrounding the end wall, and the air inlet portion 7 includes a first air inlet portion 71, which is arranged on the peripheral wall of the first extension portion 1221. Due to the special structure of the first extension portion 1221 and the flow direction of the airflow around the first extension portion 1221 is along the radial direction of the first extension portion 1221, the different opening methods of the air inlet portion 7 on the first extension portion 1221 will greatly affect the distribution of the airflow in the clothing processing chamber 201 and the size of the airflow flow. Therefore, the air inlet portion 7 includes a first air inlet portion 71, and the first air inlet portion 71 is arranged on the peripheral wall of the first extension portion 1221. The airflow flowing along the radial direction of the first extension portion 1221 can directly enter the clothing processing chamber 201 through the first air inlet portion 71 arranged on the peripheral wall of the first extension portion 1221. The airflow will not generate excessive loss in the process of entering the clothing processing chamber 201, thereby ensuring the flow rate and flow velocity of the airflow entering the clothing processing chamber 201, and further ensuring the drying effect of the dryer 1000.

[0075] In some embodiments, the end wall of the first extension portion 1221 is a non-porous structure; or, there is a gap between the end wall of the first extension portion 1221 and the cavity wall of the ventilation cavity 101, and the air inlet portion 7 includes a second air inlet portion 72 and the second air inlet portion 72 is arranged on the end wall of the first extension portion 1221.

[0076] According to some embodiments of the utility model, the end wall of the first extension portion 1221 is not provided with an air inlet structure, that is, the end wall of the first extension portion 1221 is a non-porous structure. At this time, the end wall of the first extension portion 1221 can be integrated with the air duct shell 13 to further increase the volume of the clothing processing chamber 201, or the end wall of the first extension portion 1221 is spaced apart from the cavity wall of the ventilation cavity 101 and there is a gap between the two.

[0077] According to other embodiments of the present invention, Figure 2 The air inlet portion 7 also includes a second air inlet portion 72, and the second air inlet portion 72 is arranged on the end wall of the first extension portion 1221. That is to say, part of the air flow can enter the clothing processing chamber 201 through the second air inlet portion 72 arranged on the end wall of the first extension portion 1221, thereby increasing the air inlet area, further increasing the air flow rate, and improving the drying effect of the dryer 1000.

[0078] like Fig.11 and Fig.13 As shown, the clothing processing drum 2 has a first annular flange 211 extending in a direction close to the support assembly 12, and the first annular flange 211 defines a vent 202. The support assembly 12 can cover the vent 202 by cooperating with the first annular flange 211 to prevent the clothing in the clothing processing chamber 201 from escaping from the clothing processing chamber 201 at the vent 202, thereby damaging the clothing and affecting the operation of the dryer 1000.

[0079] The first annular flange 211 movably cooperates with the support assembly 12 so that the clothing processing drum 2 can rotate relative to the support assembly 12 to achieve the function of turning over the clothing.

[0080] Reference Fig.11 and Fig.13 Since the first annular flange 211 is easy to collide with the supporting assembly 12 during the installation of the clothing processing drum 2, and the strength at the first annular flange 211 is low, and the edge of the first annular flange 211 is sharp, which will affect the safety of the installation process. Therefore, a curling structure 2111 is provided at one end of the first annular flange 211 close to the supporting assembly 12. The curling structure 2111 can, on the one hand, prevent the end of the first annular flange 211 from being too sharp and affecting the safety during the installation process, and on the other hand, can improve the strength at the edge of the first annular flange 211, and prevent the first annular flange 211 from being deformed when the first annular flange 211 is affected by external force.

[0081] Combination Figure 10-13 In the illustrated embodiment, a sealing ring 3 is provided between the clothing processing drum 2 and the support assembly 12. In order to avoid friction generated during the relative rotation between the clothing processing drum 2 and the support assembly 12, a gap exists between the clothing processing drum 2 and the support assembly 12. Furthermore, in order to achieve the sealing of the clothing processing chamber 201 and avoid the air flow escaping from the gap between the clothing processing drum 2 and the support assembly 12 and causing air volume loss, a sealing ring 3 is provided between the clothing processing drum 2 and the support assembly 12. The sealing ring 3 is arranged around the vent 202 to ensure the sealing effect of the sealing ring 3 on the vent 202.

[0082] Furthermore, since the clothing processing drum 2 is rotatable relative to the supporting assembly 12, in order to fix the sealing ring 3 and prevent the sealing ring 3 structure from falling off and deforming during the rotation of the clothing processing drum 2 relative to the supporting assembly 12, the sealing ring 3 is fixedly connected to one of the clothing processing drum 2 or the supporting assembly 12 and movably cooperates with the other.

[0083] like Figure 10-13 As shown, the support assembly 12 has an annular support protrusion 14 extending in a direction close to the clothing treatment drum 2, and the first annular flange 211 is sleeved on the outer side of the annular support protrusion 14. The cooperation between the first annular flange 211 and the annular support protrusion 14 can locate the position of the clothing treatment drum 2 during the installation process of the clothing treatment drum 2, thereby ensuring the accuracy of the setting position of the clothing treatment drum 2, and the setting of the first annular flange 211 and the annular support protrusion 14 can increase the area of ​​the matching part between the clothing treatment drum 2 and the support assembly 12, thereby increasing the sealing area of ​​the sealing structure set between the two, thereby ensuring the sealing of the clothing treatment chamber 201.

[0084] Reference Fig.11 and Fig.13 The sealing ring 3 at least includes a first sealing portion 31, which is arranged between the first annular flange 211 and the annular support protrusion 14 to seal the gap between the first annular flange 211 and the annular support protrusion 14. In addition, the sealing ring 3 is connected to the first annular flange 211 and movably cooperates with the annular support protrusion 14. The surface of the first annular flange 211 is flat, which makes it easier for the sealing ring 3 to be connected to the first annular flange 211.

[0085] Furthermore, the sealing ring 3 also includes: a second sealing portion 32 and a third sealing portion 33. The arrangement of the second sealing portion 32 and the third sealing portion 33 can increase the sealing area of ​​the sealing ring 3 and further ensure the sealing effect of the sealing ring 3 on the gap between the laundry processing drum 2 and the supporting assembly 12.

[0086] Among them, the third sealing part 33 is connected to one end of the first sealing part 31 and is movably matched with the support assembly 12. The setting of the third sealing part 33 greatly increases the matching area between the sealing ring 3 and the support assembly 12, further avoiding the airflow from overflowing through the gap between the sealing ring 3 and the support assembly 12, and ensuring the sealing of the sealing ring 3. The second sealing part 32 is connected to the side of the first annular flange 211 facing away from the first sealing part 31, so that the sealing ring 3 can protect the first annular flange 211 and avoid the first annular flange 211 from colliding with the support assembly 12 and deforming. At the same time, the third sealing part 33 is connected between the first sealing part 31 and the second sealing part 32, and the first sealing part 31 and the second sealing part 32 are connected to the first annular flange 211, that is, the two ends of the sealing ring 3 are connected to the first annular flange 211, which can stably fix the sealing ring 3 as a whole on the first annular flange 211.

[0087] Among them, the thickness of the first sealing part 31, the second sealing part 32 and the third sealing part 33 can be designed and cut according to the size of the installation gap. In some embodiments, the first sealing part 31 and / or the second sealing part 32 can adopt a double-layer sealing felt, and the third sealing part 33 can adopt a single-layer sealing felt. The two adjacent layers of sealing felt are connected by bonding, seams, etc., which are not limited here.

[0088] like Figure 3 and Figure 4As shown, the clothes dryer 1000 further includes a mounting base 4, which defines an air duct 401 to connect the clothing processing chamber 201 and the ventilation chamber 101, and a heating element is arranged in the air duct 401. During the operation of the clothes dryer 1000, the wet and cold airflow in the clothing processing chamber 201 passes through the air duct 401 defined by the mounting base 4, is heated and dehumidified in the air duct 401, passes through the air port 1213, and enters the ventilation chamber 101 defined by the air duct 401 shell assembly 1 under the drive of the wind wheel 8, and the dry and hot airflow in the ventilation chamber 101 then enters the clothing processing chamber 201 through the air inlet 7 to dry the clothes.

[0089] According to some embodiments of the utility model, the clothes dryer 1000 further includes: a heat pump system, the heat pump system includes an evaporator, a condenser and a compressor, and the heating element includes an evaporator and a condenser. In the clothing processing chamber 201, the dry hot air passes through the wet clothes, the moisture remaining on the clothes absorbs heat, and the air becomes hot and humid air. The hot and humid air enters the air duct 401, and the hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is discharged. At this time, the dry cold air continues to be heated and pressurized by the compressor and the evaporator.

[0090] like Figure 3 and Figure 4 As shown, the dryer 1000 also includes: a support member 6, which is arranged opposite to the support assembly 12, and together with the support assembly 12, limits the clothing processing drum 2 at both axial ends of the clothing processing drum 2 assembly. The two ends of the clothing processing drum 2 are respectively supported by the support assembly 12 and the support member 6 to ensure the stability of the clothing processing drum 2 assembly setting.

[0091] like Fig.10 and Fig.12 As shown, the clothing processing drum 2 includes: a drum body 22, a first annular cover 21 and a second annular cover 23. The axial ends of the drum body 22 are open. The outer ring of the first annular cover 21 is connected to the edge of the open opening at one end of the drum body 22 and the inner ring defines a ventilation port 202. The outer ring of the second annular cover 23 is connected to the edge of the open opening at the other end of the drum body 22 and the inner ring defines a clothing taking-in and putting-out port.

[0092] The first annular cover 21 and the support assembly 12 jointly cover an open end of the barrel 22, and the support assembly 12, the barrel 22, the first annular cover 21 and the second annular cover 23 jointly define a clothing processing chamber 201 having a clothing access opening, wherein the barrel 22, the first annular cover 21 and the second annular cover 23 may be an integrally formed structure, or the barrel 22, the first annular cover 21 and the second annular cover 23 may be separately formed and then fixedly connected, which is not limited here.

[0093] The provision of the first annular cover 21 increases the matching area between the laundry processing tub 2 and the supporting assembly 12, and also provides a larger space for the provision of the sealing structure, thereby ensuring the sealing performance.

[0094] A specific embodiment of the clothes dryer 1000 of the present invention is described below with reference to the accompanying drawings.

[0095] like Figure 1-Figure 9 As shown, the clothes dryer 1000 includes a mounting base 4 , a support member 6 , an air duct housing 13 , a support plate 121 , an air inlet cover 122 and a clothes processing drum 2 .

[0096] The clothes processing drum 2 and the air inlet cover 122 define a clothes processing chamber 201, which is used to accommodate clothes to be processed. The capacity of the clothes processing chamber 201 affects the number of clothes that the dryer 1000 can process at the same time and the size of clothes that the dryer 1000 can process. In order to improve the user experience, the volume of the clothes processing chamber 201 should be as large as possible. The air inlet cover 122, the air duct shell 13 and the support plate 121 define a ventilation chamber 101, and the dryer 1000 can deliver high-temperature airflow to the clothes processing chamber 201 through the ventilation chamber 101 to achieve the drying function.

[0097] like Figure 8 As shown, the support plate 121 is provided with a support portion 11, and the support portion 11 can rotatably support the laundry treatment tub 2 on the front side of the support plate 121, ensuring that the laundry treatment tub 2 can be stably arranged and stably rotated. Figure 1-Figure 8 In order to ensure the air inlet area of ​​the clothing processing chamber 201 and to ensure the volume of the clothing processing chamber 201, the dryer 1000 cancels the bearing structure for supporting the clothing processing drum 2, and supports the clothing processing drum 2 through a support portion 11 in contact with the outer surface of the clothing processing drum 2. The support portion 11 is arranged on the outer side of the clothing processing drum 2 and cooperates with the outer surface of the clothing processing drum 2. There is no need to set a structure for connecting with the bearing at the center position of the bottom wall of the clothing processing drum 2, and the rear wall of the clothing processing drum 2 can be used to open a vent 202.

[0098] There is no need to set up a structure for connecting to the bearing at the position on the support plate 121 corresponding to the clothing processing drum 2, nor is there a need to set up a structure with sufficient strength to support the clothing processing drum 2. Therefore, a larger opening 1211 can be directly opened at the position opposite to the clothing processing drum 2 to be opposite to the ventilation port 202 of the clothing processing drum 2.

[0099] like Figure 8As shown, the support portion 11 includes a support roller 11, and the support roller 11 includes at least two. The at least two support rollers 11 can limit the clothing processing drum 2 below and on both sides to ensure the stability of the clothing processing drum 2. In the process of rotation of the clothing processing drum 2, the support roller 11 is in contact with the outer surface of the clothing processing drum 2 and can roll relatively, and there is rolling friction between the two. The support roller 11 provides a stable friction force while the friction resistance between the two is small, which is conducive to ensuring the stability of the rotation of the clothing processing drum 2.

[0100] The clothing processing drum 2 has an annular mating wall, and multiple supporting rollers 11 cooperate with the annular mating wall. The cross-section of the annular mating wall is circular. The roundness of the circle formed by the cross-section at the mating point between the annular mating wall and the supporting rollers 11 determines the smoothness of the rotation of the clothing processing drum 2. The rounder the circle, the less likely the clothing processing drum 2 is to experience abnormal conditions such as jumping during rotation, thereby ensuring that the clothing processing drum 2 has less noise during operation.

[0101] The annular matching wall extends along the axial direction of the laundry processing tub 2 , and the supporting roller 11 can provide a supporting force radially pointing to the center of the laundry processing tub 2 through the annular matching wall, thereby ensuring the stability of the setting of the laundry processing tub 2 .

[0102] Alternatively, the annular mating wall extends outward along the axial direction of the clothing processing drum 2 toward the clothing access port 2012, whereby the supporting roller 11 can give the clothing processing drum 2 a radial force pointing to the center of the circle to ensure the stability of the setting of the clothing processing drum 2 and an axial forward force, thereby avoiding the axial position of the clothing processing drum 2 from being offset, ensuring the stability of the operating position of the clothing processing drum 2, and avoiding the clothing processing drum 2 from moving back and forth and colliding with the air duct shell assembly.

[0103] According to some embodiments of the utility model, the angle between the annular mating wall and the central axis of the clothing processing drum 2 is less than 45°, so as to ensure the contact area between the annular mating wall and the support roller 11, and avoid the contact area between the annular mating wall and the support roller 11 being too small, which may cause the local structure of the clothing processing drum 2 to be subjected to excessive force and cause structural deformation.

[0104] According to some embodiments of the present invention, the axial direction of the support roller 11 is parallel to the axial direction of the clothing processing drum 2 to ensure rolling contact between the support roller 11 and the clothing processing drum 2 during rotation of the clothing processing drum 2, and the axial dimension of the annular matching wall of the clothing processing drum 2 is larger than the axial dimension of the support roller 11 to ensure the contact area between the support roller 11 and the annular matching wall while avoiding the axial end of the support roller 11 from colliding with the clothing processing drum 2, or avoiding the clothing processing drum 2 from falling off the support roller 11 and affecting the operation stability.

[0105] The annular mating wall is located at the first annular cover 21. The molding process of the first annular cover 21 can ensure the strength of the annular mating wall and the roundness of the circular cross-section of the annular mating wall, thereby ensuring the operating stability of the dryer and reducing the noise during the operation of the dryer.

[0106] The air duct shell 13 defines a ventilation cavity 101 with an opening on one side, and the support assembly 12 is connected to the air duct shell 13 to cover the opening on one side of the ventilation cavity 101, wherein the support assembly 12 includes a support plate 121 and an air inlet cover 122, and the support plate 121 is arranged between the clothing processing drum 2 and the air duct shell 13 to provide an installation position for the air duct shell 13 and the clothing processing drum 2. The air duct shell 13 is fixedly arranged inside the dryer 1000 through the support plate 121, and the clothing processing drum 2 is supported on the support plate 121 by the support portion 11.

[0107] The clothing processing drum 2 defines a clothing processing chamber 201 having a clothing access opening at one end and a ventilation opening 202 at the other end. The edge of the ventilation opening 202 movably cooperates with the support assembly 12 to ensure that the clothing processing drum 2 can rotate relative to the air duct 401 shell assembly 1, thereby realizing the flipping of clothing during the drying process and achieving a more uniform drying effect.

[0108] The support plate 121 has a through opening 1211. Specifically, the support plate 121 has a through opening 1211 at a position corresponding to the vent 202 of the clothing processing drum 2. The airflow in the ventilation cavity 101 can flow out of the ventilation cavity 101 through the through opening 1211, and the airflow can enter the clothing processing cavity 201 through the vent 202. The air inlet hood 122 is arranged between the ventilation cavity 101 and the clothing processing cavity 201, and the air inlet hood 122 covers the through opening 1211 and the vent 202 at the same time. One side surface of the air inlet hood 122, the air duct shell 13 and the support plate 121 jointly define the ventilation cavity 101, and the other side surface of the air inlet hood 122, the clothing processing drum 2 jointly define the clothing processing cavity 201, and the airflow can pass through the air inlet hood 122. The airflow in the ventilation cavity 101 can directly enter the clothing processing cavity 201 through the air inlet part 7 provided on the air inlet hood 122.

[0109] At least a portion of the air inlet cover 122 extends in a direction away from the clothes processing drum 2 to form a first extension portion 1221. The first extension portion 1221 extends from a side opening of the air duct housing 13 into the ventilation cavity 101, and the air inlet portion 7 is disposed at the first extension portion 1221. By designing the first extension portion 1221 on the support assembly 12, the capacity of the clothes processing cavity 201 can be further increased, and the clothes dryer 1000 can process more and larger clothes at the same time.

[0110] The first extension portion 1221 is provided with an air inlet portion 7 which is connected with the clothing processing chamber 201 and the ventilation chamber 101. The air flow can enter the clothing processing chamber 201 through the air inlet portion 7 provided on the first extension portion 1221. Since the first extension portion 1221 is protruded into the ventilation chamber 101, the air inlet portion 7 is arranged inside the ventilation chamber 101, so that the air inlet portion 7 can better receive the air flow, reduce the resistance of the air flow in the process of flowing into the clothing processing chamber 201, and increase the air volume in the clothing processing chamber 201.

[0111] Due to the special structure of the first extension portion 1221, the flow direction of the airflow in the ventilation cavity 101 around the first extension portion 1221 flows radially along the first extension portion 1221. The different opening methods of the air inlet portion 7 on the first extension portion 1221 will greatly affect the distribution and flow of the airflow in the clothing processing cavity 201. Therefore, the air inlet portion 7 includes a first air inlet portion 71, and the first air inlet portion 71 is arranged on the peripheral wall of the first extension portion 1221. That is to say, by opening an air inlet structure on the peripheral wall of the first extension portion 1221, the airflow flowing radially along the first extension portion 1221 can directly enter the clothing processing cavity 201 through the first air inlet portion 71 arranged on the peripheral wall. The airflow will not generate excessive loss in the process of entering the clothing processing cavity 201, thereby ensuring the flow rate and flow velocity of the airflow entering the clothing processing cavity 201, and further ensuring the drying effect of the dryer 1000.

[0112] The air inlet area of ​​the first air inlet portion 71 is S1, and the total air inlet area of ​​the air inlet portion 7 is S, and S1 and S satisfy the condition: 0.05≤S1 / S≤1, that is, the air inlet area of ​​the first air inlet portion 71 is not less than five percent of the total air inlet area. In other words, an air inlet structure must be provided on the peripheral wall of the first extension portion 1221 for the air intake of the clothing processing chamber 201, thereby, the airflow radially flowing along the clothing processing drum 2 assembly can directly enter the clothing processing chamber 201 through the first air inlet portion 71 provided on the peripheral wall, and the airflow will not generate excessive loss in the process of entering the clothing processing chamber 201, thereby ensuring the flow rate and flow velocity of the airflow entering the clothing processing chamber 201, and further ensuring the drying effect of the dryer 1000.

[0113] Moreover, S1 / S may be equal to 1, that is, the air inlet portion 7 may only include the first air inlet portion 71 arranged on the peripheral wall of the first extension portion 1221, and the air inlet structure may not be arranged on the end wall of the first extension portion 1221, that is, the end wall of the first extension portion 1221 is a non-porous structure. At this time, the end wall of the first extension portion 1221 may be integrated with the air duct shell 13, or the end wall of the first extension portion 1221 may be separated from the air duct shell 13 and arranged at intervals.

[0114] The first air inlet portion 71 includes a plurality of first air inlet holes 711, and the plurality of first air inlet holes 711 are arranged at axial and / or circumferential intervals on the peripheral wall of the first extension portion 1221. Thus, the first air inlet holes 711 are evenly distributed on the peripheral wall of the first extension portion 1221. During the rotation of the clothing processing drum 2, the airflow can stably enter the clothing processing chamber 201 through the evenly arranged first air inlet holes 711, thereby ensuring the stability of the airflow in the clothing processing chamber 201.

[0115] According to other embodiments of the utility model, the air inlet portion 7 also includes a second air inlet portion 72, and the second air inlet portion 72 is arranged on the end wall of the first extension portion 1221. That is to say, part of the airflow can enter the clothing processing chamber 201 through the second air inlet portion 72 arranged on the end wall of the first extension portion 1221, thereby increasing the air inlet area, further increasing the airflow flow rate, and improving the drying effect of the dryer 1000.

[0116] The second air inlet portion 72 includes a plurality of second air inlet holes 721, and the plurality of second air inlet holes 721 are arranged at radial and / or circumferential intervals on the end wall of the first extension portion 1221. Thus, the second air inlet holes 721 are evenly distributed on the end wall of the first extension portion 1221. During the rotation of the clothing processing drum 2, the airflow can stably enter the clothing processing chamber 201 through the evenly arranged second air inlet holes 721, thereby ensuring the stability of the airflow in the clothing processing chamber 201.

[0117] The size of the first extension portion 1221 affects the volume of the clothing processing chamber 201, and the diameter of the end wall of the first extension portion 1221 affects the volume of the first extension portion 1221, wherein the diameter of the barrel 22 is d1, the diameter of the end wall of the first extension portion 1221 is d2, and the ratio of d2 to d1 is 0.5-1, that is, the diameter of the end wall of the first extension portion 1221 is at least not less than half of the diameter of the barrel 22, thereby the first extension portion 1221 can be set large enough to provide sufficient volume for the clothing processing chamber 201, so as to ensure that the clothing processing chamber 201 has sufficient volume to accommodate clothing and can process more and larger clothing at the same time.

[0118] In addition, the first extension portion 1221 is provided with an air inlet 7 connected to the clothing processing chamber 201, and the air flow can enter the clothing processing chamber 201 through the air inlet 7 provided on the first extension portion 1221. Since the air inlet 7 is provided on the first extension portion 1221, the surface area of ​​the first extension portion 1221 affects the air inlet area of ​​the air inlet 7, thereby affecting the air intake flow rate and air intake speed of the dryer 1000, and further affecting the clothing processing effect of the dryer 1000. Among them, the diameter of the barrel 22 is d1, the diameter of the end wall of the first extension portion 1221 is d2, and the ratio of d2 to d1 is 0.5-1. That is to say, the diameter of the end wall of the first extension portion 1221 is at least not less than half the diameter of the barrel 22, so that the first extension portion 1221 can have a surface area large enough for the setting of the air inlet portion 7, ensuring that the clothing processing chamber 201 has a sufficiently large air inlet area, and the airflow will not generate excessive losses in the process of entering the clothing processing chamber 201, thereby ensuring the flow rate and flow velocity of the airflow entering the clothing processing chamber 201, and further ensuring the drying effect of the dryer 1000.

[0119] like Figure 2 As shown, the end wall of the first extension portion 1221 has a structural reinforcement portion 1223, and the structural reinforcement portion 1223 can reinforce the structure of the first extension portion 1221 at the end wall of the first extension portion 1221, thereby ensuring the structural strength of the end wall of the first extension portion 1221 and preventing the end wall of the first extension portion 1221 from being deformed or damaged during installation, transportation, and high wind pressure conditions.

[0120] Reference Figure 2 The structural reinforcement portion 1223 includes a reinforcement protrusion and / or a reinforcement recess, so as to utilize the reinforcement protrusion and / or the reinforcement recess to reinforce the end wall of the first extension portion 1221 to ensure the strength of the end wall of the first extension portion 1221.

[0121] Combination Figure 2 In the illustrated embodiment, the structural reinforcement portion 1223 includes: at least one first reinforcement portion 12231 and a plurality of second reinforcement portions 12232, wherein the first reinforcement portion 12231 extends in the circumferential direction of a circle, that is, the first reinforcement portion 12231 is formed as an annular reinforcement portion, so as to reinforce the structure of the end wall of the first extension portion 1221 in the circumferential direction of the first extension portion 1221, and prevent the end wall of the first extension portion 1221 from being deformed by force. The plurality of second reinforcement portions 12232 are arranged in the circumferential direction of the circle and each second reinforcement portion 12232 extends in the radial direction of the circle, that is, the plurality of second reinforcement portions 12232 are evenly distributed on the end wall of the first extension portion 1221 in the circumferential direction, ensuring that the strength of the end wall of the first extension portion 1221 is uniform, and avoiding stress concentration caused by low local strength, which affects the overall strength of the end wall of the first extension portion 1221 and the stability of the arrangement.

[0122] like Figure 2As shown, the first reinforcement portion 12231 and the second reinforcement portion 12232 are cross-arranged to utilize the cross-arranged first reinforcement portion 12231 and the second reinforcement portion 12232 to improve the continuity of force when passing through the structural reinforcement portion 1223, which is beneficial to the continuous transmission of force and further improves the strength of the end wall of the first extension portion 1221.

[0123] like Figure 10-13 As shown, the end wall of the first extension part 1221 is connected to the peripheral wall of the first extension part 1221 by an arc transition. When the airflow passes through the connection between the end wall of the first extension part 1221 and the peripheral wall of the first extension part 1221, the airflow can be smoothly guided by the arc transition section, thereby avoiding the large resistance of the airflow when passing through the turning point, impacting the structure of the first extension part 1221 and causing noise, avoiding the loss of airflow, and reducing the difficulty of punching in the production process.

[0124] Among them, the angle between the peripheral wall of the first extension part 1221 and the end wall of the first extension part 1221 affects the air intake flow rate of the first air inlet part 71, the volume of the clothing processing chamber 201, the noise during the operation of the dryer 1000, and the difficulty of punching holes in the process of opening the air inlet holes in the air inlet area. Therefore, the peripheral wall of the first extension part 1221 extends in the direction from the end wall of the first extension part 1221 to the clothing loading and unloading port toward the peripheral wall close to the barrel 22.

[0125] According to some embodiments of the present invention, the angle between the peripheral wall of the first extension part 1221 and the plane where the end wall of the first extension part 1221 is located is 20°-80°, that is, the angle between the peripheral wall of the first extension part 1221 and the plane where the end wall of the first extension part 1221 is located is not less than 20°, so as to avoid the angle between the peripheral wall of the first extension part 1221 and the plane where the end wall of the first extension part 1221 is located being too small to affect the air volume inside the clothing treatment chamber 201 and the capacity of the clothing treatment chamber 201. The angle between the peripheral wall of the first extension part 1221 and the plane where the end wall of the first extension part 1221 is located is not greater than 80°, so as to avoid the angle between the peripheral wall of the first extension part 1221 and the plane where the end wall of the first extension part 1221 is located being too large to cause excessive noise during the operation of the dryer 1000 and affect the difficulty of punching holes on the peripheral wall of the first extension part 1221.

[0126] The support plate 121 and the air inlet cover 122 are separately molded and mechanically connected to fix the air inlet cover 122 on the support plate 121 structure. Since the air inlet cover 122 has a complex structure, it is not conducive to stamping and forming it as one piece with the support plate 121. Therefore, by stamping the support plate 121 and the air inlet cover 122 separately and then fixing them together, the production difficulty of the dryer 1000 can be reduced and the production cost of the dryer 1000 can be reduced.

[0127] Reference Figure 10-13The air inlet hood 122 has an annular limiting groove 1222 on the side facing away from the clothing processing drum 2, and the edge of the through opening 1211 has a flange structure 1212 extending into the annular limiting groove 1222. The flange structure 1212 cooperates with the annular limiting groove 1222. On the one hand, the installation position of the air inlet hood 122 can be positioned during the process of installing the air inlet hood 122 on the support plate 121 to ensure the accuracy of the installation position of the air inlet hood 122. On the other hand, the flange structure 1212 can increase the matching area between the air inlet hood 122 and the support plate 121 to ensure the stability of the connection between the air inlet hood 122 and the support plate 121.

[0128] like Fig.11 and Fig.13 As shown, the clothing processing drum 2 has a first annular flange 211 extending in a direction close to the support assembly 12, and the first annular flange 211 defines a vent 202. The support assembly 12 can cover the vent 202 by cooperating with the first annular flange 211 to prevent the clothing in the clothing processing chamber 201 from escaping from the clothing processing chamber 201 at the vent 202, thereby damaging the clothing and affecting the operation of the dryer 1000.

[0129] The first annular flange 211 movably cooperates with the support assembly 12 so that the clothing processing drum 2 can rotate relative to the support assembly 12 to achieve the function of turning over the clothing.

[0130] Reference Fig.11 and Fig.13 Since the first annular flange 211 is easy to collide with the supporting assembly 12 during the installation of the clothing processing drum 2, and the strength at the first annular flange 211 is low, and the edge of the first annular flange 211 is sharp, which will affect the safety of the installation process. Therefore, a curling structure 2111 is provided at one end of the first annular flange 211 close to the supporting assembly 12. The curling structure 2111 can, on the one hand, prevent the end of the first annular flange 211 from being too sharp and affecting the safety during the installation process, and on the other hand, can improve the strength at the edge of the first annular flange 211, and prevent the first annular flange 211 from being deformed when the first annular flange 211 is affected by external force.

[0131] Combination Figure 10-13 In the illustrated embodiment, a sealing ring 3 is provided between the clothing processing drum 2 and the support assembly 12. In order to avoid friction generated during the relative rotation between the clothing processing drum 2 and the support assembly 12, a gap exists between the clothing processing drum 2 and the support assembly 12. Furthermore, in order to achieve the sealing of the clothing processing chamber 201 and avoid the air flow escaping from the gap between the clothing processing drum 2 and the support assembly 12 and causing air volume loss, a sealing ring 3 is provided between the clothing processing drum 2 and the support assembly 12. The sealing ring 3 is arranged around the vent 202 to ensure the sealing effect of the sealing ring 3 on the vent 202.

[0132] Furthermore, since the clothing processing drum 2 is rotatable relative to the supporting assembly 12, in order to fix the sealing ring 3 and prevent the sealing ring 3 structure from falling off and deforming during the rotation of the clothing processing drum 2 relative to the supporting assembly 12, the sealing ring 3 is fixedly connected to one of the clothing processing drum 2 or the supporting assembly 12 and movably cooperates with the other.

[0133] like Figure 10-13 As shown, the support assembly 12 has an annular support protrusion 14 extending in a direction close to the clothing treatment drum 2, and the first annular flange 211 is sleeved on the outer side of the annular support protrusion 14. The cooperation between the first annular flange 211 and the annular support protrusion 14 can locate the position of the clothing treatment drum 2 during the installation process of the clothing treatment drum 2, thereby ensuring the accuracy of the setting position of the clothing treatment drum 2, and the setting of the first annular flange 211 and the annular support protrusion 14 can increase the area of ​​the matching part between the clothing treatment drum 2 and the support assembly 12, thereby increasing the sealing area of ​​the sealing structure set between the two, thereby ensuring the sealing of the clothing treatment chamber 201.

[0134] Reference Fig.11 and Fig.13 The sealing ring 3 at least includes a first sealing portion 31, which is arranged between the first annular flange 211 and the annular support protrusion 14 to seal the gap between the first annular flange 211 and the annular support protrusion 14. In addition, the sealing ring 3 is connected to the first annular flange 211 and movably cooperates with the annular support protrusion 14. The surface of the first annular flange 211 is flat, which makes it easier for the sealing ring 3 to be connected to the first annular flange 211.
