[0052] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0053] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. 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. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0056] The structure of a traditional clothes dryer includes a clothing processing drum, a rear plate and an air duct shell. The clothing processing drum defines a clothing processing chamber. A first flow channel is defined between the air duct shell and the rear plate. An air outlet area is formed on the rear plate. An air inlet area 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 first flow channel, 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 clothes treatment drum is limited by the structure, and it is impossible to process more and larger clothes at the same time, which affects the user experience. To this end, the embodiment of the utility model designs a structure that cancels the connecting bearing between the clothes treatment drum assembly and the air duct shell assembly, and sets the rotatable limit of the clothes treatment drum assembly inside the dryer through the support roller. As a result, the bottom structure of the clothes treatment drum assembly and the structure on the air duct shell assembly corresponding to the clothes treatment drum assembly can be more flexibly deformed according to different needs without considering the support fixation and strength issues, thereby improving the performance of the dryer.

[0058] Since there is no fixed connection structure between the clothing processing drum assembly and the front support member and the rear air duct shell assembly, the clothing processing drum assembly is first installed and matched with one side structure of the air duct shell assembly or the support member, and is only limited on one side. When installing and matching with the other side structure, the clothing processing drum assembly is easily rolled left and right or moved forward and backward due to external forces. It will not only detach from the already matched structure, but also easily detach from the installation position, making the next production and installation process difficult.

[0059] To this end, the embodiment of the utility model designs a dryer 1000 with a pre-positioning member 9 on the mounting seat 4, whereby the clothing processing drum assembly 2 can be pre-positioned at the position to be installed before the front support member 6 and the rear air duct shell assembly 1 are fully installed, and is not easily affected by external forces and separated from the position to be installed during the installation process, thereby reducing the difficulty of production and installation of the dryer 1000.

[0060] Reference below Figure 1-Figure 14A clothes dryer 1000 according to an embodiment of the present invention is described.

[0061] The clothes dryer 1000 according to the embodiment of the present invention may include: a mounting seat 4 , an air duct housing assembly 1 , a support member 6 and a clothes processing drum assembly 2 .

[0062] Among them, the mounting seat 4 defines an air duct, and the air duct shell assembly 1 and the support member 6 are arranged on the mounting seat 4 and are arranged relatively to each other. The mounting seat 4 can form the basis of the internal structure of the entire dryer 1000. Specifically, the air duct shell assembly 1 and the support member 6 are fixedly arranged on the front and rear sides of the mounting seat 4, wherein the air duct shell assembly 1 is located on the rear side of the clothing processing drum assembly 2, and the support member 6 is located on the front side of the clothing processing drum assembly 2.

[0063] The axial ends of the clothes treatment drum assembly 2 are respectively supported between the air duct shell assembly 1 and the support member 6, that is, the clothes treatment drum assembly 2 is located above the mounting seat 4. Since the clothes treatment drum assembly 2 will rotate relative to the air duct shell assembly 1, the mounting seat 4 and the support member 6, after the clothes treatment drum assembly 2, the support member 6 and the air duct shell assembly 1 are installed, there is a gap between the clothes treatment drum assembly 2 and the top of the mounting seat 4 to ensure that the clothes treatment drum assembly can be stably arranged in the dryer 1000 and rotate, so as to avoid friction caused by contact between the two, which affects the normal rotation of the clothes treatment drum assembly 2 and the service life of the dryer 1000.

[0064] Since the axial ends of the clothes treatment drum assembly 2 are respectively supported between the air duct shell assembly 1 and the support member 6, that is, there is no fixed connection structure between the axial ends of the clothes treatment drum assembly 2 and the air duct shell assembly 1 and the support member 6, specifically, the clothes treatment drum assembly 2 is supported on the support member 6 in a manner that can be. The support member 6 is provided with a plurality of support parts, and the outer surface of the clothes treatment drum assembly 2 cooperates with the plurality of support parts to be supported on the plurality of support parts. Further, the clothes treatment drum assembly 2 is supported on the air duct shell assembly 1 in a manner that can be.

[0065] The air duct shell assembly 1 is provided with multiple supporting parts, and the outer surface of the clothing processing drum assembly 2 cooperates with the multiple supporting parts to be supported on the multiple supporting parts. Compared with the method in the prior art that the clothing processing drum assembly 2 is rotatably connected to the air duct shell assembly 1 by a bearing structure arranged at the central axis of the clothing processing drum assembly 2, in the embodiment of the utility model, the clothing processing drum assembly 2 is limited by cooperating with the outer surface of the clothing processing drum assembly 2 by multiple supporting parts arranged on the air duct shell assembly 1, and there is no need to set a bearing structure at the bottom of the clothing processing drum assembly 2. The bottom structure of the clothing processing drum assembly 2 and the structure on the air duct shell assembly 1 corresponding to the clothing processing drum assembly 2 can be more flexibly deformed according to different needs without considering support fixation and strength issues, thereby improving the performance of the dryer 1000. For example, a clothing processing chamber 201 with a larger volume, or a clothing processing drum assembly 2 with a higher air intake efficiency can be defined, thereby improving the user experience.

[0066] Furthermore, since there is no need to consider support, fixation and strength issues, the part of the structure corresponding to the air duct housing assembly 1 and the clothing treatment drum assembly 2 does not need to have sufficient strength to assume the responsibility of supporting and fixing the clothing treatment drum assembly 2. Therefore, the part corresponding to the air duct housing assembly 1 and the clothing treatment drum assembly 2 can be provided with a through opening 1011, and the air duct housing assembly 1 defines a ventilation cavity 101 with a through opening 1011 on one side facing the support member 6, that is, facing the clothing treatment drum assembly 2.

[0067] The clothing processing drum assembly 2 defines a clothing processing chamber 201, and the clothing processing chamber 201 is connected to the air duct and the ventilation chamber 101. That is to say, the flow path of the airflow in the dryer 1000 is that the airflow in the ventilation chamber 101 enters the clothing processing chamber 201, passes through the clothing processing chamber 201, and then returns to the ventilation chamber 101 through the air duct.

[0068] Among them, the mounting seat 4 is provided with a pre-positioning member 9, which is used to pre-position the clothing processing drum assembly 2 before installing the clothing processing drum assembly 2, so as to limit the clothing processing drum assembly 2 at a certain position. At this time, the clothing processing drum assembly 2 is not easily affected by external forces and changes its position, which facilitates the installation of subsequent structures and simplifies the installation process of the clothing processing drum assembly 2.

[0069] According to some embodiments of the present invention, the pre-positioning member 9 can simultaneously limit the axial position of the clothing processing drum assembly 2 at both axial ends of the clothing processing drum assembly 2. At this time, the installation process of the clothing processing drum assembly 2 can be as follows: first, the support member 6 and a structure in the air duct shell assembly 1 are fixedly set on the mounting seat 4, and then the clothing processing drum assembly 2 is matched with it, and at the same time, the clothing processing drum assembly 2 is pre-positioned by using the pre-positioning member 9 to ensure that the clothing processing drum assembly 2 is stably limited at the preset position before matching with another structure.

[0070] Since there is a gap between the laundry processing drum assembly 2 and the mounting seat 4 after the laundry processing drum assembly 2 is installed, there is a certain height difference between the position where the laundry processing drum is pre-positioned by the pre-positioning member 9 and the actual installation position of the laundry processing drum assembly 2. Therefore, before the laundry processing drum assembly 2 is matched with the other side structure, the laundry processing drum assembly 2 needs to be lifted up so that the other side structure can be matched with the laundry processing drum assembly 2, and then the other side structure is installed on the mounting seat 4.

[0071] Alternatively, in other embodiments, the pre-positioning member 9 is detachably or height-adjustably arranged on the mounting seat 4, and the position where the clothing processing drum assembly 2 is pre-positioned by the pre-positioning member 9 can be at the same height as the actual installation position of the clothing processing drum assembly 2. In this case, the clothing processing drum assembly 2 can be firstly arranged on the mounting seat 4, and then the air duct shell assembly 1 and the support member 6 can be installed on the mounting seat 4, and then the pre-positioning member 9 can be removed or shortened.

[0072] According to other embodiments of the utility model, the pre-positioning member 9 only axially limits the clothing treatment drum assembly 2 at one axial end of the clothing treatment drum assembly 2. At this time, the installation process of the clothing treatment drum assembly 2 can be as follows: first, the support member 6 and the structure of the duct shell assembly 1 that is away from the axial end that can be limited by the pre-positioning member 9 are fixedly set on the mounting seat 4, and then the clothing treatment drum assembly 2 is matched with it, and the clothing treatment drum assembly 2 is pre-positioned by the pre-positioning member 9 at the same time, ensuring that the clothing treatment drum assembly 2 is stably limited at the preset position before matching with another structure. Then lift the clothing treatment drum assembly 2 so that the other structure matches with the clothing treatment drum assembly 2, and then install the other side structure on the mounting seat 4.

[0073] Alternatively, in other embodiments, the pre-positioning member 9 is detachably or height-adjustably arranged on the mounting seat 4. In this case, the pre-positioning member 9 pre-positions the clothing processing drum assembly 2 at the same height as the actual installation position of the clothing processing drum assembly 2. In this case, the other side structure can be installed on the mounting seat 4 first, and then the pre-positioning member 9 can be removed or shortened.

[0074] According to the dryer 1000 of the embodiment of the utility model, the dryer 1000 has better performance and is easy to produce and install, thereby reducing the production difficulty and production cost.

[0075] Combination Figure 6-Figure 11 In the illustrated embodiment, the pre-positioning member 9 has a limiting convex portion 91, which is used to stop at one axial end of the clothing treatment tub assembly 2 to axially limit the clothing treatment tub assembly 2. The setting of the limiting convex portion 91 can ensure the accuracy of the pre-positioning position of the clothing treatment tub assembly 2 in the axial direction. At the pre-positioning position, the clothing treatment tub assembly 2 and the support member 6 or the air duct housing assembly 1 on the other side can have a stable matching relationship, and it is not easy to fall off from the matching position, ensuring that the installation process is more stable and convenient.

[0076] Reference Figure 6-Figure 11 The pre-positioning member 9 has a limiting surface 921, which is used to cooperate with the outer peripheral wall of the clothing processing drum assembly 2. The limiting surface 921 can support the clothing processing drum at the lower side of the clothing processing drum assembly 2, and the heights of the limiting surface 921 at both ends of the circumferential direction of the clothing processing drum assembly 2 are higher than the height in the middle. Since the cross-section of the clothing processing drum assembly 2 is circular, it is easy to roll on the horizontal plane. Therefore, by using the limiting surface 921 with the heights of both ends higher than the height in the middle, the position of the clothing processing drum assembly 2 can be limited in the horizontal direction. Under the action of gravity, the clothing processing drum assembly 2 is limited at the limiting surface 921 to prevent the clothing processing drum assembly 2 from rolling, thereby ensuring the stability of the setting of the clothing processing drum assembly 2 when it is predetermined.

[0077] like Fig.11 As shown, the limiting surface 921 includes a concave arc surface that cooperates with the outer peripheral wall of the clothing processing drum assembly 2. The concave arc surface is formed into a structure with high sides and low middle, which can simultaneously support and limit the clothing processing drum assembly, prevent the clothing processing drum assembly 2 from rolling, and ensure the stability of the clothing processing drum assembly 2 when it is predetermined.

[0078] In other embodiments, the limiting surface 921 includes at least two oppositely disposed inclined surfaces and at least two inclined surfaces extend downward in a direction close to each other, and the clothing processing drum assembly is limited between the two oppositely disposed inclined surfaces, and the inclined surfaces can support the clothing processing drum assembly 2 upwardly with an inclination, and can also simultaneously realize the support and limitation of the clothing processing drum assembly. The two inclined surfaces limit the clothing processing drum assembly 2 on both sides of the clothing processing drum assembly 2, thereby preventing the clothing processing drum assembly 2 from rolling and ensuring the stability of the predetermined setting of the clothing processing drum assembly 2.

[0079] The pre-positioning member 9 and the clothing treatment drum assembly 2 are limited by surface-to-surface cooperation, which can avoid local force on the clothing treatment drum assembly 2, causing deformation or even damage to the clothing treatment drum assembly 2, and ensure the structural stability of the clothing treatment drum assembly 2 during installation.

[0080] Combination Figure 6-Figure 11 In the illustrated embodiment, the pre-positioning member 9 includes: a limiting plate 91 and a plurality of connecting ribs 92. The plurality of connecting ribs 92 are arranged at intervals and connected between the mounting seat 4 and the limiting plate 91. The connecting ribs 92 can strengthen the structure of the limiting plate 91 to ensure that the limiting plate 91 has sufficient strength to support the clothing processing drum assembly 2. The connecting ribs 92 arranged at intervals reduce the weight of the dryer 1000 while ensuring the load-bearing capacity.

[0081] Among them, the limiting surface 921 is formed on the upper surface of the connecting rib 92 to support the clothing processing drum assembly 2 below the clothing processing drum assembly 2, and the limiting plate 91 is used to stop at one axial end of the clothing processing drum assembly 2 to axially limit the clothing processing drum assembly 2 and ensure the accuracy of the axial position of the clothing processing drum assembly 2 during the pre-positioning process.

[0082] The limiting protrusion 91 for axially limiting the clothing processing drum assembly 2, that is, the above-mentioned limiting plate 91 structure, and the limiting surface 921 for limiting the clothing processing drum assembly 2 in the horizontal direction of the clothing processing drum assembly 2 are integrated into a structure formed by the limiting plate 91 and the connecting rib 92, thereby simplifying the structure of the pre-positioning member 9.

[0083] like Figure 5-Figure 11 As shown, the mounting seat 4 includes: a seat body 41 and a cover plate 42, the seat body 41 having a concave cavity with an opening facing upward, the cover plate 42 being arranged on the top of the seat body 41, and being used for closing the opening of the concave cavity to define an air duct with the seat body 41, wherein the structural strength of the portion of the cover plate 42 corresponding to the air duct is relatively low, the pre-positioning member 9 is arranged on the top wall and / or side wall of the cover plate 42 and protrudes from the upper surface of the cover plate 42 to avoid direct compression of the cover plate 42 by the clothing treatment drum assembly 2 during pre-positioning, and the portion of the cover plate 42 with relatively low structural strength being compressed, resulting in structural deformation or rupture, and reserving some space between the cover plate 42 and the clothing treatment drum assembly 2, which is not only beneficial to the fixed connection of other structures in the dryer 1000, but also beneficial to the subsequent adjustment of the position of the clothing treatment drum assembly 2.

[0084] Furthermore, the clothes dryer 1000 also includes: a heat pump system, which includes an evaporator, a condenser and a compressor, and the evaporator and the condenser are arranged in the air duct. The clothes processing drum assembly 2 defines a clothes processing chamber 201. In the clothes processing chamber 201, the dry hot air passes through the wet clothes, and 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, 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, forming a high-pressure dry and hot airflow, and then returns to the clothes processing chamber 201 through the ventilation chamber 101.

[0085] like Figure 3-Figure 5 and Fig.13As shown, the above-mentioned supporting part may include a supporting roller 11, and the air duct shell assembly 1 is provided with multiple supporting rollers 11. The outer surface of the clothing processing drum assembly 2 cooperates with the multiple supporting rollers 11 to be supported on the multiple supporting rollers 11. Compared with the method in the prior art that the clothing processing drum assembly 2 is rotatably connected to the air duct shell assembly 1 through a bearing structure arranged at the central axis of the clothing processing drum assembly 2, in the embodiment of the utility model, the clothing processing drum assembly 2 is limited by cooperating with the outer surface of the clothing processing drum assembly 2 through the multiple supporting rollers 11 arranged on the air duct shell assembly 1. There is no need to set a bearing structure at the bottom of the clothing processing drum assembly 2. The bottom structure of the clothing processing drum assembly 2 and the structure on the air duct shell assembly 1 corresponding to the clothing processing drum assembly 2 can be more flexibly deformed according to different needs without considering support fixation and strength issues, thereby improving the performance of the dryer 1000. For example, a clothing processing chamber 201 with a larger volume or a clothing processing drum assembly 2 with a higher air intake efficiency can be defined, thereby improving the user experience.

[0086] Among them, refer to Figure 6 and Figure 8 The clothing processing drum assembly 2 may include: a drum body 21 and an air inlet cover 22, wherein one axial end of the drum body 21 has an open opening 2011 and the other end has a clothing access opening 2012 for taking clothing in and out, the air inlet cover 22 covers the open opening 2011 to define a clothing processing chamber 201 connected to the clothing access opening 2012 with the drum body 21, wherein the air inlet cover 22 and the drum body 21 may be an integrally formed structure, or the air inlet cover 22 and the drum body 21 may be separately formed and then fixedly connected, which is not limited here.

[0087] Further, refer to Fig.14 The clothing processing chamber 201 includes: an inner cavity of the barrel 21 and an air inlet chamber defined by an air inlet cover 22 and connected to the inner cavity of the barrel 21, at least a portion of the air inlet cover 22 extends from the opening 1011 into the ventilation chamber 101, and the portion extending into the ventilation chamber 101 can be used to expand the clothing processing chamber 201, thereby increasing the capacity of the clothing processing chamber 201, thereby the dryer 1000 can process more and larger clothes at the same time.

[0088] Among them, the pre-positioning member 9 is used to cooperate with the drum 21 before installing the clothing processing drum assembly 2, so that the pre-positioning member 9 is suitable for the dryer 1000 in different embodiments in which the air inlet hood 22 is fixed to the drum 21 or the air inlet hood 22 is cooperated with the drum 21 but not fixed, and the height of the setting position of the pre-positioning member 9 is lower to avoid interfering with the normal operation of the clothing processing drum assembly 2.

[0089] Specifically, the air inlet cavity includes a first chamber 2014, and the air inlet cover 22 has a first extension portion 223 extending in a direction away from the barrel 21. The first extension portion 223 extends from the opening 1011 into the ventilation cavity 101, and the first extension portion 223 defines the first chamber 2014 for expanding the capacity of the clothing processing cavity 201. The design of the first extension portion 223 on the air inlet cover 22 increases the capacity of the clothing processing cavity 201, and the clothes dryer 1000 can process more and larger clothes at the same time. The first extension portion 223 is provided with an air inlet portion 7 connected to the clothing processing cavity 201, and the airflow in the ventilation cavity 101 can enter the clothing processing cavity 201 through the air inlet portion 7 provided on the first extension portion 223.

[0090] Since the first extension portion 223 extends into the ventilation cavity 101, the wind resistance is reduced, and the air flow rate and air intake efficiency of the material processing cavity can be improved.

[0091] Further, the first extension part 223 includes an end wall and a peripheral wall surrounding the end wall, which are arranged opposite to the clothing taking-in and putting-out opening 2012. Since the first extension part 223 has a special structure and the airflow in the ventilation cavity 101 flows in the radial direction of the clothing processing drum assembly 2 around the first extension part 223, the different opening modes of the air inlet part 7 on the first extension part 223 will greatly affect the distribution and flow rate of the airflow in the clothing processing cavity 201. Therefore, the air inlet part 7 includes a first air inlet part 71, which is arranged on the peripheral wall of the first extension part 223. That is, by opening the air inlet structure on the peripheral wall of the first extension part 223, the airflow flowing in the radial direction of the clothing processing drum assembly 2 can directly enter the clothing processing cavity 201 through the first air inlet part 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 clothes dryer 1000.

[0092] According to some embodiments of the utility model, the end wall of the first extension portion 223 is not provided with the air inlet portion 7, that is, the end wall of the first extension portion 223 is a non-porous structure. At this time, the end wall of the first extension portion 223 can be integrated with the air duct shell assembly 1, or the end wall of the first extension portion 223 can be spaced apart from the inner wall of the air duct shell assembly 1.

[0093] According to other embodiments of the utility model, there is a gap between the end wall of the first extension portion 223 and the cavity wall of the ventilation cavity 101, and 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 223. That is to say, part of the airflow can pass through the gap between the end wall of the first extension portion 223 and the cavity wall of the ventilation cavity 101 and enter the clothing processing cavity 201 through the second air inlet portion 72 arranged on the end wall of the first extension portion 223, thereby increasing the air inlet area, further increasing the airflow rate, and improving the drying effect of the dryer 1000.

[0094] like Fig.14 As shown, the air inlet cavity defined by the air inlet cover 22 includes a first cavity 2014 and a second cavity 2015, and the air inlet cover 22 also includes a second extension portion 226 extending in a direction away from the barrel 21, and the second extension portion 226 is a non-porous structure and defines the second cavity 2015. The second extension portion 226 is located between the first extension portion 223 and the barrel 21, and the first extension portion 223 extends in a direction away from the barrel 21 relative to the second extension portion 226, so that in the axial direction of the barrel 21, the second cavity 2015 is connected between the first cavity 2014 and the inner cavity of the barrel 21. The provision of the second cavity 2015 further increases the volume of the laundry processing cavity 201, and the dryer 1000 can process more laundry at the same time.

[0095] The arrangement of the first extension portion 223 and the second extension portion 226 allows the air inlet cover 22 to form a stepped structure in the axial direction of the clothing processing drum assembly 2, which facilitates the molding and processing of the air inlet cover 22. In addition, the second extension portion 226 defines a certain space between the outer side and the rear wall of the air duct shell assembly 1 and the clothing processing drum assembly 2, and this space can be used for the installation of the support roller 11. The arrangement of the support roller 11 will not affect the arrangement of other internal structures of the dryer 1000, thereby avoiding the arrangement of the support roller 11 affecting the size of the dryer 1000.

[0096] Reference Fig.14 A sealing ring 3 is provided between the side of the air duct shell assembly 1 facing the clothing processing drum assembly 2 and the clothing processing drum assembly 2. The sealing ring 3 surrounds the outside of the through opening 1011, that is, also surrounds the outside of the air inlet portion 7, so as to achieve sealing between the air duct shell assembly 1 and the clothing processing drum assembly 2.

[0097] Combination Figure 1-Figure 4 , Figure 13-14 In the illustrated embodiment, the air duct housing assembly 1 comprises: a support plate 12 and an air duct housing 13. A through opening 1011 is provided on the support plate 12, the air duct housing 13 is connected to one side of the support plate 12 in the thickness direction and covers the through opening 1011, the air duct housing 13 defines a ventilation cavity 101, wherein the support roller 11 is provided on the other side of the support plate 12 in the thickness direction.

[0098] That is, the air duct shell 13 is arranged on one side of the support plate 12, and a ventilation cavity 101 having a through opening 1011 is defined between the air duct shell 13, and the clothes processing drum assembly 2 is arranged on the other side of the support plate 12, and at least a part of the clothes processing drum assembly 2 is arranged opposite to the through opening 1011, and the part arranged opposite to the through opening 1011 forms the air inlet 7 of the clothes processing cavity 201. The support roller 11 is arranged on the same side as the clothes processing drum assembly 2, and is arranged below the clothes processing drum assembly 2 to support the clothes processing drum assembly 2. The airflow in the ventilation cavity 101 can enter the clothes processing cavity 201 directly through the air inlet 7 opened at the corresponding part of the clothes processing drum assembly 2 and the through opening 1011. The structure of the support plate 12 is simple, and the production cost is reduced.

[0099] The pre-positioning member 9 is arranged on one side of the mounting seat 4 close to the supporting plate 12 .

[0100] A specific embodiment of the clothes dryer 1000 of the present invention is described below with reference to the accompanying drawings.

[0101] like Figure 1-Figure 14 As shown, the clothes dryer 1000 includes a mounting base 4 , a support member 6 , an air duct housing assembly 1 and a clothes processing drum assembly 2 .

[0102] The laundry processing drum assembly 2 defines a laundry processing chamber 201, which is used to accommodate the laundry to be processed. The capacity of the laundry processing chamber 201 affects the number of laundry that the dryer 1000 can process at the same time and the size of the laundry that the dryer 1000 can process. In order to improve the user experience, the volume of the laundry processing chamber 201 should be as large as possible. The air duct housing assembly 1 defines a ventilation chamber 101, and the dryer 1000 can deliver high-temperature airflow into the laundry processing chamber 201 through the ventilation chamber 101 to achieve the drying function.

[0103] The air duct housing assembly 1 is provided with a supporting roller 11, which can rotatably support the clothes processing drum assembly 2 at the front side of the air duct housing assembly 1, ensuring that the clothes processing drum assembly 2 can be stably arranged and rotated. Figure 1-Figure 14In order to ensure the air inlet area of ​​the clothing processing drum assembly 2 and the volume of the clothing processing drum assembly 2, the dryer 1000 cancels the bearing structure for supporting the clothing processing drum assembly 2, and supports the clothing processing drum assembly 2 through a supporting roller 11 in contact with the outer surface of the clothing processing drum assembly 2. The supporting roller 11 is arranged on the outer side of the clothing processing drum assembly 2 and cooperates with the outer surface of the clothing processing drum assembly 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 assembly 2. The bottom structure of the clothing processing drum assembly and the structure on the air duct shell assembly corresponding to the clothing processing drum assembly can be more flexibly deformed according to different needs without considering support fixation and strength issues, thereby improving the performance of the dryer.

[0104] The clothing processing drum assembly 2 has an annular mating wall 2261, and multiple supporting rollers 11 cooperate with the annular mating wall 2261. The cross-section of the annular mating wall 2261 is circular. The roundness of the circle formed by the cross-section at the mating point of the annular mating wall 2261 and the supporting rollers 11 determines the smoothness of the clothing processing drum assembly 2 during rotation. The rounder the circle, the less likely the clothing processing drum assembly 2 will experience abnormal conditions such as jumping during rotation, thereby ensuring that the clothing processing drum assembly 2 produces less noise during operation.

[0105] Among them, the annular matching wall 2261 extends axially along the clothing processing drum assembly 2, and the supporting roller 11 can provide a radial supporting force pointing to the center of the clothing processing drum assembly 2 through the annular matching wall 2261, thereby ensuring the stability of the clothing processing drum assembly 2.

[0106] Alternatively, the annular mating wall 2261 extends outward along the axial direction of the clothing processing drum assembly 2 toward the clothing access port 2012, whereby the supporting roller 11 can provide the clothing processing drum assembly 2 with a force in the radial direction pointing to the center of the circle to ensure the stability of the setting of the clothing processing drum assembly 2 and a forward force in the axial direction, thereby avoiding the axial position of the clothing processing drum assembly 2 from being offset, ensuring the stability of the operating position of the clothing processing drum assembly 2, and avoiding the clothing processing drum assembly 2 from moving back and forth and colliding with the air duct shell assembly.

[0107] According to some embodiments of the utility model, the angle between the annular mating wall 2261 and the central axis of the clothing processing drum assembly 2 is less than 45°, so as to ensure the contact area between the annular mating wall 2261 and the support roller 11, and avoid the contact area between the annular mating wall 2261 and the support roller 11 being too small, resulting in excessive force on the local structure of the clothing processing drum assembly 2, causing structural deformation.

[0108] 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 assembly 2 to ensure rolling contact between the support roller 11 and the clothing processing drum assembly 2 during rotation of the clothing processing drum assembly 2, and the axial dimension of the annular matching wall 2261 of the clothing processing drum assembly 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 2261 while avoiding the axial end of the support roller 11 from colliding with the clothing processing drum assembly 2, or avoiding the clothing processing drum assembly 2 from falling off the support roller 11, which would affect the operation stability.

[0109] The annular matching wall 2261 is located at the air inlet cover 22. The molding process of the air inlet cover 22 can ensure the strength of the annular matching wall 2261 and the roundness of the circular cross-section of the annular matching wall 2261, thereby ensuring the operating stability of the dryer and reducing the noise during the operation of the dryer.

[0110] Among them, one side of the air duct shell assembly 1 has a through opening 1011, and a part of the clothing processing drum assembly 2 extends from the through opening 1011 into the ventilation cavity 101, thereby, the clothing processing drum assembly 2 can extend backward until it extends into the ventilation cavity 101, and the clothing processing drum assembly 2 can be designed to be deeper without changing the external dimensions of the dryer 1000, thereby increasing the capacity of the clothing processing cavity 201, and the dryer 1000 can process more and larger clothes at the same time, thereby improving the user experience.

[0111] The clothes treatment drum assembly 2 can extend backward until it reaches the ventilation cavity 101. The clothes treatment drum assembly 2 has an air inlet 7, which can directly connect the ventilation cavity 101 and the clothes treatment cavity 201. That is to say, during the flow of air, the air in the ventilation cavity 101 can directly enter the clothes treatment cavity 201 through the air inlet 7. On this basis, the original complex air outlet area on the air duct housing assembly 1 can directly open a larger opening 1011, thereby reducing the production cost of the dryer 1000.

[0112] There is no need to set a structure for connecting to the bearing at the position on the air duct shell assembly 1 corresponding to the clothing processing drum assembly 2, nor is there a need to set a structure with sufficient strength to support the clothing processing drum assembly 2. Therefore, a larger opening 1011 can be directly opened at the position opposite to the clothing processing drum assembly 2 to be opposite to the air inlet area of ​​the clothing processing drum assembly 2, so as to reduce the resistance to the airflow flowing to the clothing processing chamber 201 while allowing part of the clothing processing drum assembly 2 to extend from the opening 1011 into the ventilation chamber 101.

[0113] like Fig.13As shown, the support rollers 11 include at least two, and the at least two support rollers 11 can limit the clothing processing drum assembly 2 at the bottom and both sides of the clothing processing drum assembly 2 to ensure the stability of the clothing processing drum assembly 2, and during the rotation of the clothing processing drum assembly 2, the support rollers 11 are in contact with the outer surface of the clothing processing drum assembly 2 and can roll relative to each other, and there is rolling friction between the two. The support rollers 11 provide a stable friction force while the friction resistance between the two is small, which is beneficial to ensure the stability of the rotation of the clothing processing drum assembly 2.

[0114] Furthermore, the annular matching wall 2261 is located at the second extending portion 226 on the air inlet cover 22 .

[0115] Combination Figure 1-Figure 12 In the illustrated embodiment, the air duct housing assembly 1 comprises: a support plate 12 and an air duct housing 13. A through opening 1011 is provided on the support plate 12, the air duct housing 13 is provided on one side of the support plate 12 in the thickness direction and covers the through opening 1011, the air duct housing 13 defines a ventilation cavity 101, wherein the support roller 11 is provided on the other side of the support plate 12 in the thickness direction.

[0116] That is, the air duct shell 13 is arranged on one side of the support plate 12, and a ventilation cavity 101 having a through opening 1011 is defined between the air duct shell 13, and the clothes processing drum assembly 2 is arranged on the other side of the support plate 12, and at least a part of the clothes processing drum assembly 2 is arranged opposite to the through opening 1011, and the part arranged opposite to the through opening 1011 forms the air inlet 7 of the clothes processing cavity 201. The support roller 11 is arranged on the same side as the clothes processing drum assembly 2, and is arranged below the clothes processing drum assembly 2 to support the clothes processing drum assembly 2. The airflow in the ventilation cavity 101 can enter the clothes processing cavity 201 directly through the air inlet 7 opened at the corresponding part of the clothes processing drum assembly 2 and the through opening 1011. The structure of the support plate 12 is simple, and the production cost is reduced.

[0117] like Figure 6 As shown, the laundry treatment drum assembly 2 includes: a drum body 21 and an air inlet cover 22. The annular matching wall 2261 is located at the air inlet cover 22, and the annular matching wall 2261 is arranged at the air inlet cover 22. The molding process of the air inlet cover 22 can ensure the strength of the annular matching wall 2261 and the roundness of the circular cross-section of the annular matching wall 2261, thereby ensuring the operating stability of the dryer 1000 and reducing the noise during the operation of the dryer 1000.

[0118] like Fig.14As shown, the air inlet cover 22 defines an air inlet cavity, which includes a first chamber 2014 and a second chamber 2015. The air inlet cover 22 also includes a second extension portion 226 extending in a direction away from the barrel 21. The second extension portion 226 is a non-porous structure and defines the second chamber 2015. The second extension portion 226 is located between the first extension portion 223 and the barrel 21 so that the second chamber 2015 is connected between the first chamber 2014 and the inner cavity of the barrel 21. The provision of the second chamber 20152015 further increases the volume of the laundry processing chamber 201201, and the dryer 1000 can process more laundry at the same time.

[0119] The arrangement of the first extension portion 223 and the second extension portion 226 allows the air inlet cover 22 to form a stepped structure in the axial direction of the clothing processing drum assembly 2, which facilitates the molding and processing of the air inlet cover 22. In addition, the second extension portion 226 defines a certain space between the outer side and the rear wall of the air duct shell assembly 1 and the clothing processing drum assembly 2, and this space can be used for the installation of the support roller 11. The arrangement of the support roller 11 will not affect the arrangement of other internal structures of the dryer 1000, thereby avoiding the arrangement of the support roller 11 affecting the size of the dryer 1000.

[0120] Among them, at least a portion of the second extension portion 226 forms an annular matching wall 2261. Specifically, the outer surface of the peripheral wall of the second extension portion 226 is formed as the annular matching wall 2261. The annular matching wall 2261 is arranged at the second extension portion 226, so that the support roller 11 is arranged at a position closer to the rotation axis position of the clothing processing drum assembly 2, thereby reducing the influence of the cross-sectional roundness on the rotation of the clothing processing drum assembly 2.

[0121] Reference Fig.14 A sealing ring 3 is provided between the side of the air duct shell assembly 1 facing the clothing processing drum assembly 2 and the clothing processing drum assembly 2. The sealing ring 3 surrounds the outside of the through opening 1011, that is, also surrounds the outside of the air inlet portion 7, so as to achieve sealing between the air duct shell assembly 1 and the clothing processing drum assembly 2.

[0122] like Fig.14 As shown, the barrel 21 includes: a barrel body 211 and a barrel cover 212. The barrel body 211 has an open opening 2011 at one axial end. The barrel cover 212 is connected to the other axial end of the barrel body 21. The middle part of the barrel cover 212 defines a clothing access opening 2012. Clothes can be placed into or taken out of the clothing processing chamber 201 through the clothing access opening 2012 defined by the barrel cover 212.

[0123] The barrel 21 has an open opening 2011 at one axial end and a clothing access opening 2012 at the other end. The air inlet hood 22 covers the open opening 2011 to define a clothing processing chamber 201 connected to the clothing access opening 2012 with the barrel 21, wherein the air inlet hood 22 and the barrel 21 can be formed separately and then fixedly connected.

[0124] At least a portion of the air inlet cover 22 extends from the opening 1011 into the ventilation cavity 101 to increase the capacity of the clothing processing cavity 201 so that the dryer 1000 can process more and larger clothing at the same time.

[0125] Specifically, the air inlet cover 22 has a first extension portion 223 extending in a direction away from the barrel 21. The design of the first extension portion 223 on the air inlet cover 22 increases the capacity of the clothing processing chamber 201, and more and larger clothing can be processed simultaneously. The first extension portion 223 is provided with an air inlet portion 7 communicating with the clothing processing chamber 201, and airflow can enter the clothing processing chamber 201 through the air inlet portion 7 provided on the first extension portion 223.

[0126] In addition, the first extension portion 223 is provided with an air inlet portion 7 in communication with the clothing processing chamber 201, and airflow can enter the clothing processing chamber 201 through the air inlet portion 7 provided on the first extension portion 223. Since the air inlet portion 7 is provided on the first extension portion 223, the surface area of ​​the first extension portion 223 affects the air inlet area of ​​the air inlet portion 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.

[0127] like Fig.12 As shown, the shape of the through opening 1011 is circular to correspond to the shape of the first extension portion 223 extending into the ventilation cavity 101, so that the first extension portion 223 can be set as large as possible.

[0128] Furthermore, since the through-port 1011 is connected to the ventilation cavity 101, the airflow in the ventilation cavity 101 can flow out through the through-port 1011. When the diameter of the outer peripheral wall of the cylinder 21 is smaller than the diameter of the through-port 1011, the airflow will flow out through the gap between the edge of the through-port 1011 and the outer peripheral wall of the cylinder 21, causing air volume loss. Therefore, the diameter of the outer peripheral wall of the cylinder 21 is larger than the diameter of the through-port 1011.

[0129] like Figure 2 , Figure 4 , Figure 6 and Fig.12 As shown, the air duct housing assembly 1 also has an air outlet 1012 located on one side of the through opening 1011, and a wind wheel 8 arranged opposite to the air outlet 1012 is arranged in the ventilation cavity 101.

[0130] 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 1012, and enters the ventilation chamber 101 defined by the air duct 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 of the clothing processing drum assembly 2, and performs drying treatment on the clothing.

[0131] Combination Figure 3-Figure 6 as well as Fig.13 and Fig.14 In the illustrated embodiment, the mounting seat 4 is located below the laundry processing tub assembly 2 , and the wind wheel 8 is located obliquely below the laundry processing tub assembly 2 .

[0132] 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.

[0133] like Figure 3 and Figure 4 As shown, the dryer 1000 also includes: a support member 6, which is arranged opposite to the air duct shell assembly 1, and together with the air duct shell assembly 1, limits the clothing processing drum assembly 2 at both axial ends of the clothing processing drum assembly 2, and the two ends of the clothing processing drum assembly 2 are respectively supported by the air duct shell assembly 1 and the support member 6 to ensure the stability of the setting of the clothing processing drum assembly 2.

[0134] In some embodiments, reference Figure 6 A plurality of second rollers 61 are disposed on the support member 6 , and the outer surface of the laundry treatment drum assembly 2 cooperates with the plurality of second rollers 61 to be supported on the plurality of support rollers 11 and the plurality of second rollers 61 at the same time.

[0135] There is no fixed connection structure between the axial ends of the clothing processing drum assembly 2 and the air duct shell assembly 1 and the support member 6. After the clothing processing drum assembly 2 is first installed and matched with the structure on one side of the air duct shell assembly 1 or the support member 6, it is only limited on one side. When it is installed and matched with the structure on the other side, the clothing processing drum assembly 2 is easily rolled left and right or moved forward and backward due to external forces. It will not only detach from the already matched structure, but also easily detach from the installation position, making the next production and installation process difficult.

[0136] Therefore, a pre-positioning member 9 is provided on the mounting seat 4, which is used to pre-position the clothing processing drum assembly 2 before installing the clothing processing drum assembly 2, so as to limit the clothing processing drum assembly 2 at a certain position. At this time, the clothing processing drum assembly 2 is not easily affected by external forces and changes its position, which facilitates the installation of subsequent structures and simplifies the installation process of the clothing processing drum assembly 2.

[0137] The axial direction of the clothes treatment drum extends along the front-rear direction of the clothes dryer 1000, the air duct housing assembly 1 is arranged behind the mounting seat 4, the clothes treatment drum assembly 2 is located above the mounting seat 4, the support member 6 is arranged in front of the mounting seat 4, and the pre-positioning member 9 is arranged between the support plate 12 and the support member 6 and close to one side of the support plate 12. The pre-positioning member 9 only limits the axial position of the clothes treatment drum assembly 2 at the rear end of the clothes treatment drum assembly 2. The support member 6 and the upper cover of the mounting seat 4 are integrally formed.

[0138] Specifically, the assembly steps of the clothes dryer 1000 are as follows: first, the support member 6 is fixedly arranged on the mounting seat 4, and then the clothes processing drum assembly 2 is matched with the support member 6, ensuring that the front end of the clothes processing drum assembly 2 is placed on the second roller 61, and the clothes taking and placing opening 2012 is aligned with the hole edge of the support member 6. At the same time, the rear end of the clothes processing drum assembly 2 is arranged above the pre-positioning member 9, and the clothes processing drum assembly 2 is pre-positioned by the pre-positioning member 9 to ensure that the clothes processing drum assembly 2 is stably limited to the preset position before being matched with the support plate 12.

[0139] Then lift the laundry treatment drum assembly 2, and after the through hole on the support plate 12 corresponds to the first extension portion 223 and the rear end of the laundry treatment drum assembly 2 is placed on the support roller 11, the support plate 12 is fixed to the mounting seat 4. Finally, the air duct housing 13 and the support plate 12 are assembled together.

[0140] The pre-positioning member 9 includes: a limiting plate 91 and a plurality of connecting ribs 92, wherein the plurality of connecting ribs 92 are arranged at intervals and connected between the mounting seat 4 and the limiting plate 91, and the upper surfaces of the plurality of connecting ribs 92 arranged at intervals together form a concave arc surface with high sides and low middle, which is used to limit the position of the clothing processing drum assembly 2 in the horizontal direction. Under the action of gravity, the clothing processing drum assembly 2 is limited at the limiting surface 921 formed as a concave arc surface, thereby preventing the clothing processing drum assembly 2 from rolling and ensuring the stability of the clothing processing drum assembly 2 when it is predetermined.

[0141] The limiting plate 91 stops at one axial end of the clothing treatment drum assembly 2 to axially limit the clothing treatment drum assembly 2, so that at the pre-positioned position, the clothing treatment drum assembly 2 and the support member 6 can have a stable matching relationship and are not easy to fall off from the matching position, ensuring that the installation process is more stable and convenient.
