DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0037] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0038] Clothes dryers can use the dry hot air generated by electricity to evaporate and dry washed clothes instantly. Because it shortens the drying time of clothes and is not restricted by weather conditions, it plays an important role, especially in humid weather such as the return of the south wind, so it provides great convenience for people's lives and is becoming more and more popular.

[0039] At present, clothes dryers are mainly divided into hanger-type dryers and drum-type dryers, among which drum-type dryers are further divided into direct-discharge type, condensation type, heat pump type and other types. Drum-type dryers generally include a drum and a base, and the base supports the drum from both ends of the drum body. One end of the drum body is provided with an opening for taking and putting clothes when in use, and the other end is closed and equipped with a drum shaft. Therefore, the base generally provides a roller at the open end of the drum body for support, and the drum shaft end is provided with a bearing to cooperate with the drum shaft to achieve support, thereby causing the outer peripheral surface section of the drum body to lack effective support.

[0040] But at the same time, on the one hand, a belt is also provided on the outer peripheral surface section of the cylinder, the belt is tensioned through the outer peripheral surface section and the driving wheel, and generates a downward tensioning force on the cylinder; on the other hand, during the transportation of the dryer, bumps, vibrations and falling impacts are inevitable, causing the drum to swing with the vibration impact.

[0041] Based on the above two aspects and the lack of effective support for the outer circumferential surface of the cylinder, the swing amplitude of the outer circumferential surface of the cylinder will be greater than the swing amplitude of the two end parts, which will easily cause the end of the cylinder (especially the drum shaft end of the cylinder) to deform, thereby causing the drum to run irregularly and produce abnormal noise.

[0042] In order to solve the above problems, the present application provides a drum supporting device and a clothes dryer.

[0043] The drum support device and the dryer provided in the present application will be described in detail below with reference to the accompanying drawings.

[0044] Figure 1 A partial structural schematic diagram of a clothes dryer is provided for this application; Figure 2 for Figure 1 A schematic diagram of the structure of the middle roller support device; Figure 3 for Figure 2 A schematic structural diagram of the middle roller support device from another perspective.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the roller support device 100 provided in the present application includes an elastic bracket 110 and a rotating assembly 120; the elastic bracket 110 includes a mounting portion 111 and a supporting portion 112, the mounting portion 111 is used to connect with a set mounting position, the supporting portion 112 is connected to the mounting portion 111, and at least one of the supporting portion 112 and the mounting portion 111 has a bending section, and the bending section is used to generate elastic deformation when the elastic bracket 110 is compressed; the rotating assembly 120 is rotatably installed on the supporting portion 112, and the rotating assembly 120 is used to abut against the cylinder 200 of the roller and rotate with the cylinder 200, and provide elastic support to the cylinder 200 through the elastic bracket 110.

[0046] It can be understood that the set installation position is located on the base 300 and is directly below the outer peripheral surface section of the cylinder 200. Therefore, when the installation portion 111 is connected to the set installation position, the roller support device 100 is between the roller and the base 300 and abuts against the cylinder 200. In addition, since the set installation position is set on the flat part of the base 300, when the installation portion 111 is connected to the set installation position, the contact parts of the two are parallel and fit each other.

[0047] In some embodiments, the elastic bracket 110 has a bending section only on the mounting portion 111, or has a bending section only on the supporting portion 112. Figure 3As shown, the elastic bracket 110 has two bending sections, one is located on the mounting portion 111, and the other is located on the support portion 112, so that the elastic bracket 110 can have the ability to generate elastic deformation and obtain elastic potential energy through the bending section. When the elastic bracket 110 is subjected to pressure from the outer peripheral surface section of the cylinder 200 or the pressure is further increased, the pressure is transmitted from the cylinder 200 to the rotating assembly 120, and then transmitted from the rotating assembly 120 to the support portion 112, and further transmitted to the mounting portion 111 through the support portion 112. The elastic bracket 110 will swing the support portion 112 and part of the mounting portion 111 toward the base 300 through the bending of the bending section, thereby forming elastic deformation and accumulating elastic potential energy. The swing amplitude of each of the support portion 112 and part of the mounting portion 111 is proportional to the pressure of the outer peripheral surface section of the cylinder 200 (i.e., the swing amplitude of the outer peripheral surface section). If only the supporting portion 112 has the bending section, only the supporting portion 112 swings, and if only the mounting portion 111 has the bending section, the supporting portion 112 swings along with a portion of the mounting portion 111 .

[0048] When the pressure of the outer peripheral surface of the cylinder 200 on the elastic support 110 is reduced due to its own swing or even removed in a short time, the elastic support 110 will release the elastic potential energy through the bending section and restore the deformation, and always maintain support for the cylinder 200 during the process.

[0049] It is understandable that the cylinder 200 will rotate during the swing, vibration and normal operation. The rotating assembly 120 is rotatably assembled on the end of the support portion 112, so that the rotating assembly 120 abuts against the cylinder 200 and rotates with the cylinder 200, thereby reducing the friction between the roller support device 100 and the outer peripheral surface of the cylinder 200, avoiding the support portion 112 directly contacting the cylinder 200 and scratching the cylinder 200, while enhancing the elastic support effect of the roller support device 100 on the cylinder 200 and slowing down the swing amplitude of the cylinder 200.

[0050] Therefore, the roller support device 100 provided by the present application is provided with an elastic bracket 110 and a rotating assembly 120, so that the rotating assembly 120 abuts against the cylinder 200 and rotates with the cylinder 200, and the elastic bracket 110 provides elastic support for the cylinder 200 through the bending section. Therefore, when the cylinder 200 is impacted or bumped during transportation, the elastic bracket 110 of the roller support device 100 cooperates with the rotating assembly 120 to effectively buffer and reduce the amplitude of the swing and vibration of the outer peripheral surface of the cylinder 200, while avoiding damage to the cylinder 200, thereby reducing the possibility of deformation of the end of the cylinder 200, and finally avoiding irregular operation of the roller due to deformation and generating abnormal noise.

[0051] like Figure 2 , Figure 3As shown, in some embodiments, the number of the rotating components 120 and the number of the supporting parts 112 are both at least two, and the rotating components 120 and the supporting parts 112 are correspondingly arranged.

[0052] It is understandable that the provision of at least two support portions 112 can enable the roller support device 100 to provide more comprehensive, stable and reliable support to the cylinder 200 and make the force on the cylinder 200 more balanced, thereby improving the buffering effect on the swing and vibration of the cylinder 200.

[0053] In this regard, the rotating assembly 120 and the supporting portion 112 need to be arranged correspondingly to ensure consistency in the support and buffering of the barrel 200 .

[0054] It should be noted that the corresponding arrangement of the rotating components 120 and the supporting parts 112 herein includes but is not limited to a one-to-one corresponding arrangement of the same number, but the rotating components 120 can be arranged on each supporting part 112 in an appropriate and uniform number according to the specific working conditions, so that each supporting part 112 and the corresponding rotating components 120 are consistent. For example, in other embodiments of the present application, each supporting part 112 can be provided with a corresponding set of rotating components 120, or each supporting part 112 can be provided with two sets of rotating components 120, and the present application does not limit this, but the shape and structure of the supporting part 112 need to be adaptively adjusted to accommodate multiple sets of rotating components 120.

[0055] In this embodiment, the number of the support parts 112 is two, while in other embodiments, the number of the support parts 112 can also be an even number of four or six that are symmetrically arranged in pairs, or an odd number of three or five that are partially symmetrically arranged, so as to provide support for the cylinder 200 from at least two directions, and the present application does not impose any restrictions on this.

[0056] Figure 4 for Figure 2 Schematic diagram of the structure of the elastic support.

[0057] like Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the mounting portion 111 includes a mounting segment 1111 and support segments 1112 located at both ends of the mounting segment 1111, and the support segment 1112 is at least partially inclined relative to the mounting segment 1111 to form a bending segment; the mounting segment 1111 has a mounting hole 1113, and the mounting hole 1113 is used to connect to the set mounting position.

[0058] It should be noted that the supporting segment 1112 includes a first sub-segment 1112 a and a second sub-segment 1112 b which are connected to each other, wherein the first sub-segment 1112 a is also connected to the mounting segment 1111 , and the second sub-segment 1112 b is also connected to the supporting portion 112 .

[0059] In this embodiment, only the first sub-section 1112a is tilted relative to the mounting section 1111 to form Figure 3 As shown in the β angle, the first sub-segments 1112a at both ends of the mounting segment 1111 form the β angle, while the second sub-segment 1112b remains parallel to the mounting segment 1111.

[0060] It is understandable that by providing a partially upwardly inclined support segment 1112 (first sub-segment 1112a) to form a bent segment, the non-inclined portion of the support segment 1112 (second sub-segment 1112b) can be higher than the mounting segment 1111, thereby forming a swing space. When the elastic bracket 110 is subjected to pressure, the second sub-segment 1112b can be swung toward the base 300 where the mounting segment 1111 is located, reducing the β angle, so that the support segment 1112 generates elastic deformation.

[0061] In other embodiments, the first sub-segment 1112a may be parallel to the mounting segment 1111, and the second sub-segment 1112b may be inclined relative to the first sub-segment 1112a and the mounting segment 1111; or the first sub-segment 1112a and the second sub-segment 1112b may be inclined relative to the mounting segment 1111, wherein the degree of inclination of the second sub-segment 1112b may be consistent with that of the first sub-segment 1112a, or may be greater than or less than that of the first sub-segment 1112a; or the first sub-segment 1112a may be inclined, and the portion of the second sub-segment 1112b close to the first sub-segment 1112a may be parallel to the mounting segment 1111 and the portion close to the support portion 112 may be inclined, and the present application does not impose any restrictions on this.

[0062] It should be noted that, according to specific needs, the lengths of the first sub-segment 1112a and the second sub-segment 1112b can be adjusted; or the preset value of the angle β (the inclination angle of the first sub-segment 1112a) can be adjusted, and the value range of the angle β can be 15°≤∠β≤60°, and the present application does not limit the specific preset value of the angle β. When the preset value of the angle β is less than 15°, the second sub-segment 1112b is closer to the plane where the set installation position is located, so that the swing space is small, the swing of the second sub-segment 1112b is limited, and the elastic support effect of the bending section is reduced; and when the preset value of the angle β is greater than 60°, the first sub-segment 1112a is tilted to a state close to the vertical state, and the elastic deformation capacity between the first sub-segment 1112a and the second sub-segment 1112b is poor at this time due to the short length of the first sub-segment 1112a.

[0063] It is understandable that the mounting holes 1113 are at least two circular through holes evenly arranged on the mounting section 1111, and are specifically set as four circular through holes in the present application. In other embodiments, the mounting holes 1113 may also be at least two bar holes, diamond holes, or through holes of other suitable shapes, and the present application does not limit the number and shape of the mounting holes 1113.

[0064] like Figure 1 , Figure 2 and Figure 3 As shown, after the mounting hole 1113 is connected to the set mounting position, the two need to be fixed by a fastener 1114, so that the roller support device 100 can provide stable and reliable support for the roller on the base 300, and the roller support device 100 will not be offset relative to the base 300 during the swing, vibration or rotation of the drum body 200. The fastener 1114 can be a screw or a bolt to facilitate the subsequent disassembly, maintenance and replacement of the elastic bracket 110.

[0065] In addition, it should be noted that the present application is not limited to the use of fasteners 1114 to achieve the connection between the mounting hole 1113 and the set mounting position, and other fixed connection methods, such as welding, riveting, etc., are also acceptable.

[0066] In some embodiments, one end of the support segment 1112 facing away from the mounting segment 1111 is connected to the support portion 112, and the support portion 112 is inclined relative to the mounting segment 1111 to form a bending segment; there are two support portions 112, the two support portions 112 are symmetrically arranged relative to the mounting segment 1111, and the distance between the two support portions 112 gradually decreases from the mounting portion 111 toward the rotating component 120.

[0067] It is understandable that the two support parts 112 are symmetrically and obliquely arranged at the two ends of the mounting part 111 and connected to the support section 1112, so that the support part 112 can provide support to the cylinder 200 in two symmetrical directions, so as to improve the stability of the support of the support part 112. The bending section is formed between the end of the support part 112 and the second sub-section 1112b, so that the bending section can use the support part 112 and the mounting part 111 as its load-bearing structure, thereby increasing the moment of the roller 121 on the second bending section when the roller support device 100 is subjected to force, further enhancing the elastic deformation performance of the roller support device 100, so as to improve the elastic support effect of the roller support device 100.

[0068] In other embodiments, a bending section may be formed in the middle of the support portion 112, or an additional bending section may be further formed at one end of the support portion 112 away from the mounting portion 111, so as to further improve the elastic deformation performance on the basis of the existing elastic bracket 110, and the present application does not make any specific restrictions on this.

[0069] In this embodiment, the two support portions 112 are symmetrically arranged and gradually approach each other on the same side of the mounting portion 111 to form an inverted V-shaped structure, and are formed relative to the mounting portion 111 as shown in FIG. Figure 3 The angle α shown is an acute angle at this time, so as to minimize the component force of the pressure of the cylinder 200 acting vertically on the extension direction of the support part 112, and improve the stability of the support. Among them, the preset value range of the angle α can be 30°≤∠α≤80°, and the present application does not limit the specific preset value. When the preset value of the angle α is less than 30°, for a single support part 112, its support part 112 is relatively close to the mounting part 111, so that the elastic deformation space is small, and it is easy to make the rotating component 120 and the mounting part 111 contact when under pressure, thereby interfering with the normal rotation of the rotating component 120; and for the overall support part 112, between two adjacent support parts 112, the rotating components 120 installed on their respective support parts 112 will abut against each other when under pressure and cannot rotate normally. When the preset value of the angle α is greater than 80° or even close to 90°, the support part 112 is nearly parallel to the vertical downward pressure, and the bending section will be difficult to provide effective elastic support.

[0070] In other embodiments of the present application, according to specific working conditions, the two support parts can be gradually moved away from each other on the same side of the mounting part 111 to form a positive V-shaped structure when the pressure load of the roller support device 100 allows. At this time, the angle α is an obtuse angle, and the preset value range of the angle α can be 100°≤∠α≤150°. The specific preset value of the angle α is not limited in this embodiment. However, it should be noted that if the preset value of the angle α is less than 100°, the support part 112 will also be nearly parallel to the vertical downward pressure, resulting in the bending section being difficult to provide effective elastic support. If the preset value of the angle α is greater than 150°, the swing space of the support part 112 toward the plane where the mounting part 111 is located will be smaller, and it will be easy for the rotating component 120 to contact the plane where the mounting part 111 is located.

[0071] In some embodiments, the support portion 112 and the mounting portion 111 are integrally formed.

[0072] It is understandable that the elastic bracket 110 is an integrated structure, and can be specifically formed by bending a sheet metal part, thereby lowering the production and processing cost of the elastic bracket 110 and improving its processing efficiency.

[0073] In other embodiments, the support portion 112 and the mounting portion 111 may be processed separately and the two may be welded to form the elastic bracket 110, or the two may be connected by screws. It is only necessary to ensure that at least one of the support portion 112 or the mounting portion 111 has a bending section, and this application does not impose any restrictions on this.

[0074] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the mounting portion 111 and the supporting portion 112 are transitioned via a rounded corner 113 .

[0075] It is understandable that the sheet metal is bent to form the elastic bracket 110, which can naturally form a bent section with a rounded corner 113 transition. The rounded corner 113 transition can make the thickness of the connection between the support section 1112 and the support portion 112 more consistent, avoiding stress concentration and reducing the structural strength, and the surface of the rounded corner 113 is smoother. When the second sub-section 1112b and the support portion 112 come into contact with the base 300 due to swinging, the possibility of the bent section crushing the surface of the base 300 can be reduced, effectively extending the service life of the base 300 and even the dryer.

[0076] In other embodiments, if a non-integrated molding processing method is adopted between the support portion 112 and the mounting portion 111, such as welding, etc., the transition between the support segment 1112 and the support portion 112 can also be made through a rounded corner 113, or through a chamfered bevel, and the present application does not impose any restrictions on this.

[0077] Figure 5 for Figure 2 Schematic diagram of the structure of the rotating component.

[0078] like Figure 4 and Figure 5 As shown, in some embodiments, the rotating assembly 120 includes a roller 121 and a rotating shaft 122 coaxially disposed on the roller 121, and the support portion 112 has extended edges 1121 on both sides, and the extended edges 1121 have through holes; the rotating shaft 122 is inserted into the through hole so that a portion of the roller 121 is located between the two extended edges 1121.

[0079] It is understandable that the rotating assembly 120 composed of the roller 121 and the rotating shaft 122 has a simple structure and is easy to implement. In order to facilitate the rotating assembly 120 to smoothly rotate and connect with the elastic bracket 110, the extended edges 1121 on both sides of the support portion 112 extend out of the upper edge of the support portion 112 on the one hand, to provide a space for the roller 121 to avoid interfering with the rotation of the roller 121; on the other hand, the extended edges 1121 can also be regarded as flanges relative to the support portion 112, so that the extended edges 1121 are perpendicular to the support portion 112, thereby facilitating the provision of through holes on the extended edges 1121 to connect with the rotating shaft 122, and the overall structure is more compact.

[0080] The extending edge 1121 is folded relative to the supporting portion 112 toward the mounting portion 111 , and in other embodiments, the extending edge 1121 may be folded relative to the supporting portion 112 away from the mounting portion 111 , which is not limited in the present application.

[0081] It should be noted that, in order to prevent the rotating shaft 122 from moving in the through hole, a limiting boss is further provided at the end of the rotating shaft 122, and the step surface of the limiting boss close to the roller 121 abuts against the outer side surface of the extension edge 1121. In addition, in order to improve the smoothness of the rotation of the roller 121, a bearing adapted to the rotating shaft 122 can be installed on the through hole, or a bearing can be installed between the rotating shaft 122 and the roller 121, and this application does not limit this.

[0082] In some embodiments, the roller 121 includes a core body 1211 and a buffer layer 1212 , the rotating shaft 122 is coaxially disposed in the core body 1211 , and the buffer layer 1212 is at least coated on the outer peripheral surface of the core body 1211 .

[0083] It can be understood that the roller 121 is composed of a core 1211 and a buffer layer 1212. On the one hand, the core 1211 with strong rigidity can be used to provide the roller 121 with greater structural strength to avoid deformation of the roller 121 and the rotating shaft 122; on the other hand, the buffer layer 1212 can also be used to make the roller 121 and the cylinder 200 in flexible contact, thereby preventing the cylinder 200 from being scratched and providing a buffer for the core 1211 and even the elastic bracket 110.

[0084] The rotating shaft 122 is coaxially disposed in the core body 1211 , and its structure is relatively compact, thereby preventing the roller 121 from being eccentric when rotating, and ensuring the stability of the rotation of the roller 121 .

[0085] It should be noted that the buffer layer 1212 is at least coated on the outer peripheral surface of the core body 1211, which can reduce the consumables of the buffer layer 1212 to reduce costs while ensuring the buffering effect of the contact between the roller 121 and the cylinder 200 as much as possible.

[0086] In other embodiments of the present application, the buffer layer 1212 may also completely cover the core 1211 , and the present application does not limit this.

[0087] The core 1211 is a metal core, and the buffer layer 1212 is a rubber layer.

[0088] It is understandable that the metal core and the rubber layer can reduce the production cost of the roller 121 as much as possible, extend the service life of the roller 121, and improve the structural strength of the roller 121 while meeting the above two purposes.

[0089] In other embodiments of the present application, a plastic core body and a rubber layer may be used to support the roller 121, so as to further reduce the production cost while ensuring the structural strength of the roller 121, and the present application does not impose any restrictions on this.

[0090] In other embodiments of the present application, at least one of an elastic reset member and a damping material member may be installed between the rotating assembly 120 and the elastic bracket 110 to provide support and protection for the roller support device. Specifically, the elastic reset member may be a coil spring disposed on the elastic bracket 110 and located below the rotating assembly 120. A damping material member made of elastic materials such as silicone rubber or polyvinyl chloride may be disposed inside the coil spring to buffer and absorb the vibration and swing impact of the roller support device 100. This further improves the maximum load and support stability of the elastic support of the roller support device, reduces the fatigue load of the elastic bracket 110, and extends the service life of the roller support device.

[0091] In addition, the present application also provides an embodiment of a dryer, which includes a base 300, a drum and a drum support device 100 provided in any of the above embodiments, wherein the drum is rotatably assembled on the base 300; the base 300 has a set mounting position, and the set mounting position is located below the outer circumferential surface of the drum body 200; the drum support device 100 is fixedly mounted on the set mounting position, rotatably abuts against the drum body 200, and provides elastic support for the drum body 200.

[0092] The roller supporting device 100 has been described in detail in the above embodiment, and will not be described again in this embodiment.

[0093] In order to ensure that the drum 200 can rotate stably on the base 300, an end support wheel 410 is provided at the rear end of the drum 200 to support the rear end of the drum 200. At the same time, the rear end of the drum 200 also has an opening for taking and placing clothes (not shown in the figure); and at the front end of the drum 200, a drum shaft 420 is provided, so the bearing and the drum shaft 420 can be used to support the front end of the drum 200; a belt 430 is wound around the outer circumferential surface of the drum 200, and the belt 430 is tensioned by the driving wheel 440, so that the belt 430 can rotate with the driving wheel 440, thereby driving the drum 200 to rotate synchronously.

[0094] It should be noted that, since the deformation probability of the front end of the cylinder 200, that is, the end where the roller shaft 420 is set, is greater than the deformation probability of the rear end of the cylinder 200, in order to give full play to the supporting effect of the roller support device 100, the installation position can be appropriately set close to the front end of the cylinder 200. Furthermore, during the specific use of the roller support device 100, the roller support device 100 can be supported from the side of the outer peripheral surface section of the cylinder 200 close to the front end.

[0095] In summary, the drum support device 100 and the clothes dryer provided in the embodiment of the present application connect the drum support device 100 with the base 300 by providing an elastic bracket 110 with a bent section and a roller 121 rotatably mounted on the elastic bracket 110, and support the drum 200 from below the drum 200. The roller 121 abuts against the drum 200 and can rotate with the drum 200, and the bent section of the elastic bracket 110 can provide effective elastic support for the drum 200 through its own elastic deformation.

[0096] In this way, during the transportation of the drum 200, if it falls and is impacted due to road bumps, the elastic bracket 110 can produce elastic deformation, and the roller 121 can rotate appropriately following the swing of the drum 200, thereby effectively buffering and reducing the swing and vibration of the outer peripheral surface of the drum 200. In this way, the possibility of deformation of the end of the drum 200, especially one end of the drum shaft 420, is reduced, so that the drum will not run irregularly due to deformation during operation, thereby generating abnormal noise.

[0097] So far, the technical solution of the present application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments, and the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
