[0040] The embodiments of the present application will be described below with reference to the accompanying drawings in the present application. It should be understood that the embodiments described below in conjunction with the accompanying drawings are exemplary descriptions for explaining the technical solutions of the embodiments of the present application, and do not constitute limitations on the technical solutions of the embodiments of the present application.

[0041] Those skilled in the art can understand that, unless specifically stated otherwise, the words "the" and "said" used herein may also include the plural form. It should be further understood that the term "comprising" used in the specification of this application means the presence of the described features, integers, steps, operations, and / or components, but does not exclude the presence of other features, information, data, steps, operations, elements, components, and / or combinations thereof supported by the art. The term "and / or" used herein means at least one of the items defined by this term. For example, "A and / or B" can be implemented as "A", or as "B", or as "A and B".

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0043] Reference Figures 1 - 2 The electric clothes dryer applicable to the embodiments of this application includes a main body 1 and a drying component. The main body 1 is used to control the extension and retraction of the drying component. The drying component is functionally divided according to the main drying items, including a main drying rack 4, a telescopic quilt drying rod 3, an electric telescopic rack 2, etc.

[0044] The electric telescopic rack 2 of the embodiments of this application includes a sunshade net frame 21 and a soft drying piece laid in the sunshade net frame 21. The electric telescopic rack 2 of this embodiment is a part extended based on the main drying rack 4. When the electric telescopic rack 2 is unfolded, the soft drying piece is unfolded as the sunshade net frame 21 extends unidirectionally. The direction in which the sunshade net frame 21 extends is defined as the front end, and conversely, the direction in which the sunshade net frame 21 contracts when the soft drying piece is retracted is defined as the rear end. A possible implementation is that the sunshade net is arranged on the longitudinal axis of the main body 1, at both longitudinal ends of the main drying rack 4. Thus, some components of the electric telescopic rack 2 are subordinate to the main drying rack 4 or shared with the main drying rack 4, which will be further explained below.

[0045] Reference Figures 2 - 6 , the sunshade net frame 21 of this application includes a pair of parallel telescopic rods 211, a first end cover 212 connecting the front ends of the telescopic rods 211, and a positioning rod 213 connecting the middle parts of the telescopic rods 211. The telescopic rods 211 always abut against the first end cover 212 forward, and with the pulling effect of the soft drying piece, the horizontal support of the sunshade net frame 21 is realized.

[0046] The telescopic rod 211 in the embodiment of the present application includes a plug 2111, a base 2112, and a spring 2113 with two ends respectively connected to the plug 2111 and the base 2112. The spring 2113 realizes telescoping under the limitation of the skeleton rod. Specifically, the skeleton rod includes an inner sleeve 2114 sleeved in the inner cavity of the spring 2113 and an outer sleeve 2115 sleeved on the outer surface of the spring 2113. Obviously, the outer diameter of the inner sleeve 2114 is smaller than the inner diameter of the outer sleeve 2115. By adjusting the lengths of the inner sleeve 2114 and the outer sleeve 2115 respectively, the inner sleeve 2114 can be partially or completely sleeved inside the outer sleeve 2115. In the embodiment of the present application, the lengths of the inner sleeve 2114 and the outer sleeve 2115 are respectively greater than half of the length of the spring 2113 but less than the total length of the spring 2113. In this way, there is always an overlapping section between the inner sleeve 2114 and the outer sleeve 2115, which can ensure the continuity of the longitudinal structure of the telescopic rod 211 and prevent loosening under normal use conditions. Further, the minimum length of the overlapping section can be limited to facilitate ensuring the structural strength of the telescopic rod 211 and avoiding breakage at the overlapping section. In a possible embodiment, the minimum length of the overlapping section is set within the range of 1 / 10 to 1 / 8 of the total length of the spring 2113.

[0047] In this embodiment, the ends of the inner sleeve 2114 and the outer sleeve 2115 away from each other translate synchronously relative to the two ends of the spring 2113, so that the inner sleeve 2114 and the outer sleeve 2115 can realize movable nesting following the compression or release of the spring 2113. The process of movable nesting causes the length of the overlapping section between the inner sleeve 2114 and the outer sleeve 2115 to change. Accordingly, the linear distance between the ends of the inner sleeve 2114 and the outer sleeve 2115 away from each other changes, causing the total length of the telescopic rod 211 to change. When the spring 2113 is compressed by an external force, the inner sleeve 2114 can be nested inside the outer sleeve 2115, thereby shortening the linear distance between the two ends of the outer sleeve 2115 and the inner sleeve 2114 and realizing the shortening of the telescopic rod 211. When the spring 2113 is in a state where the external force is removed or reduced, the elastic potential energy stored in it is released, pulling apart the linear distance between the two ends of the outer sleeve 2115 and the inner sleeve 2114 and realizing the elongation of the telescopic rod 211.

[0048] In this embodiment, the rear end of the inner sleeve 2114 is fixedly connected to the base 2112, and the front end of the outer sleeve 2115 is fixedly connected to the plug 2111. Thus, the distance between the plug 2111 and the base 2112 is the telescopic length of the telescopic rod 211 in this embodiment. The maximum extendable length of the telescopic rod 211 is determined by the minimum length of the overlapping section of the inner sleeve 2114 and the outer sleeve 2115, and the minimum compressible length of the telescopic rod 211 is determined by the longer one of the inner sleeve 2114 and the outer sleeve 2115. In order to enable the screen drying frame 21 to have better horizontal bearing capacity in this application, the lengths of the inner sleeve 2114 and the outer sleeve 2115 are configured to be the same. Thus, the minimum compressible length of the telescopic rod 211 is the length of the inner sleeve 2114 or the outer sleeve 2115.

[0049] Further, in order to improve the smoothness of the movable nesting between the inner sleeve 2114 and the outer sleeve 2115, it is preferably to set the inner sleeve 2114 and the outer sleeve 2115 as pipe bodies with circular cross-sections. On the one hand, it adapts to the cross-sectional profile of the spring 2113, and on the other hand, it reduces the occurrence of hard collisions between the outer wall of the inner sleeve 2114 and the inner wall of the outer sleeve 2115. In addition, although there is a spring 2113 blocking between the inner sleeve 2114 and the outer sleeve 2115, a certain distance should be maintained between the inner sleeve 2114 and the spring 2113, and between the outer sleeve 2115 and the spring 2113, so as to achieve clearance fit, reduce the friction between the inner sleeve 2114, the spring 2113 and the outer sleeve 2115, and reduce the telescopic resistance of the telescopic rod 211. In other implementation manners, the cross-sectional shape of the outer sleeve 2115 can adopt other implementation manners, but it should meet the principle of clearance fit with the spring 2113.

[0050] Another possible implementation manner is that the skeleton rod member includes a housing 2116 and a fixing rod 231 sleeved on the outer surface of the spring 2113. The housing 2116 can be nested inside the fixing rod 231, so that the housing 2116 and the fixing rod 231 can slide relative to each other, thereby realizing the telescoping of the telescopic rod 211. The cross-sectional shapes of the housing 2116 and the fixing rod 231 can be the same or different. However, those skilled in the art can understand that when the cross-sectional shapes of the housing 2116 and the fixing rod 231 are the same, the tightness of the fitting between the two can be higher. When the cross-sectional shapes of the housing 2116 and the fixing rod 231 are different, different functional structures can be specifically configured on the housing 2116 and the fixing rod 231 to improve the versatility of the telescopic rod 211 of this application.

[0051] The lengths of the outer shell 2116 and the fixing rod 231 are set to be similar to those of the inner sleeve 2114 and the outer sleeve 2115. The lengths of the outer shell 2116 and the fixing rod 231 are respectively greater than half of the length of the spring 2113 but less than the total length of the spring 2113, so as to facilitate an overlapping section between the outer shell 2116 and the fixing rod 231, ensuring that the connection between the outer shell 2116 and the fixing rod 231 is always continuous within the normal telescopic stroke of the spring 2113, and the longer one of the outer shell 2116 and the fixing rod 231 determines the shortest length after the telescopic rod 211 is compressed. The mutually remote ends of the outer shell 2116 and the fixing rod 231 can also be fixed and assembled using the plug 2111 and the base 2112.

[0052] Optionally, the telescopic rod 211 of the embodiment of the present application can be provided with an outer shell 2116 and / or a fixing rod 231 on the basis of configuring the inner sleeve 2114 and the outer sleeve 2115. The outer shell 2116 or the fixing rod 231 is sleeved on the outer surface of the outer sleeve 2115. The functions of the outer shell 2116 and the fixing rod 231 can, on the one hand, serve as a protective shell for the telescopic rod 211, and on the other hand, other accessories can be installed and extended on the basis of the outer shell 2116 and the fixing rod 231, so as to facilitate the telescopic rod 211 to cooperate with other mechanical equipment.

[0053] In this embodiment, the outer shell 2116 is a rectangular cross-section tube body. One end of the outer shell 2116 is fixedly connected to the plug 2111. At the same time, the outer sleeve 2115 is fixedly connected to the plug 2111, and there is a clearance between the inner wall of the outer shell 2116 and the outer wall of the outer sleeve 2115 without contact. Thus, the plug 2111 simultaneously fixes the spring 2113, the outer sleeve 2115, and the outer shell 2116. Correspondingly, the base 2112 simultaneously fixes the spring 2113 and the inner sleeve 2114.

[0054] Further, to ensure the structural stability of the outer shell 2116, a gasket 2117 is provided at the other end of the outer shell 2116. Refer to Figure 7 , in this embodiment, the gasket 2117 includes two through structures, and the two through structures are connected as a whole by a connecting strip, so that the gasket 2117 covers the surface of the outer shell 2116. Specifically, the gasket 2117 includes a circular through hole 21171 through structure for the spring 2113 (including the inner sleeve 2114) to pass through, serving as the free end, and also includes a first structural hole 21172 through structure for the outer shell 2116 to pass through, serving as the connection end. Further, a positioning ring is provided inside the free end of the gasket 2117 for the end of the outer sleeve 2115 to abut against. Thus, the length of the outer shell 2116 is equal to the length of the outer sleeve 2115, and the outer shell 2116 moves following the movement of the outer sleeve 2115.

[0055] Further, the through-structure of the gasket 2117 is defined by a structural wall. Optionally, the connecting end of the gasket 2117 forms a first structural hole 21172 that is consistent with the contour of the outer shell 2116 through the structural wall. On the basis of the first structural hole 21172, the free end of the gasket 2117 adds a structural wall with a round hole at the outermost end. The diameter of the round hole is adapted to the spring 2113 for the spring 2113 to pass through, or the diameter of the round hole is adapted to the outer sleeve 2115 to form a positioning ring that abuts against the end of the outer sleeve 2115.

[0056] Reference Figure 7 , further, a sleeve 2118 is also arranged adjacent to the front end of the connecting end of the gasket 2117 for positioning and protection. In one possible implementation, the sleeve 2118 includes a second structural hole 21181 that fits the outer shell 2116. The second structural hole 21181 forms a second structural hole 21181 that is consistent with the contour of the outer shell 2116 through the structural wall, that is, the shape of the second structural hole 21181 is the same as or similar to the shape of the first structural hole 21172. Further, a fixing plate 21182 extends from the edge of the second structural hole 21181 for limiting or as a connecting structure. The extending direction and specific structure of the fixing plate 21182 can be set according to actual needs. Assuming that the plug 2111 is defined as the front end and the base 2112 is the rear end, the sleeve 2118 is arranged at the front end of the gasket 2117, which can resist the external force from the front end or the compression displacement from the plug 2111 to the base 2112, avoiding direct damage to the bushing due to force. The sleeve 2118 can also be used as a limiting member to define the lower limit of compression. The cooperation between the sleeve 2118 and the gasket 2117 can protect the overlapping section of the inner sleeve 2114 and the outer sleeve 2115. In one implementation, the length of the gasket 2117 matches the shortest state of the overlapping section.

[0057] Reference Figures 8 - 9 , in one possible implementation, the plug 2111 and the base 2112 are respectively provided with fixing columns for fixing the ends of the spring 2113, which are used to insert into the inner cavity of the spring 2113 for fixation, or to wrap the body of the spring 2113 for fixation. Optionally, such fixing columns can be made of screw rods. The threads on the surface of the screw rods can increase the friction surface for fixing the spring 2113, or the fixing columns can be made of pin columns. The pin columns are convenient for integral molding with other components, or axial blind holes or through holes are opened inside the pin columns for fixing the ends of the spring 2113. In this embodiment, a screw rod is set as the fixing column at the plug 2111, and a pin column is set as the fixing column at the base 2112.

[0058] In this embodiment, the front end of the plug 2111 is used to tightly abut against the first end cap 212. Correspondingly, the first end cap 212 is provided with an abutting area 21232a adapted to the outer contour of the plug 2111 to prevent the plug 2111 from coming off during the extension or compression of the telescopic rod 211. Further, the plug 2111 and the abutting area 21232a can be detachably fixed to enhance the stability of the tight abutment.

[0059] The electric telescopic racks 2 provided in this embodiment are symmetrically arranged at the longitudinal ends of the main drying rack 4. Thus, the two sides of the sunshade frame 21 can share a set of bases 2112. The specific implementation method can be that the bases 2112 of a pair of parallel telescopic rods 211 are arranged on the axis of symmetry. Pin shafts 21121 for fixing the springs 2113 and the inner sleeves 2114 are arranged on both side surfaces of the base 2112. The two inner sleeves 2114 extending in opposite directions are joined together as a whole through the base 2112. Movable outer sleeves 2115 are respectively arranged on the two inner sleeves 2114. Thus, two pairs of parallel telescopic rods 211 with opposite telescopic directions are formed to form two independent sunshade frames 21.

[0060] Reference Figures 8 - 9, the first end cap 212 is provided at the front end of a pair of telescopic rods 211. As one of the lateral connection structures of the pair of telescopic rods 211, the end cap of the present application not only has functionality but also has a decorative function. Thus, inside the decorative housing 2116, the first end cap 212 of the present application is provided with a first inner cavity 2121 and a second inner cavity 2122. The first inner cavity 2121 is used to accommodate the mesh cloth 22 and its reel 223, and the second inner cavity 2122 is used to accommodate the power feeding module for driving the reel 223. In other embodiments, modules that need to be electrically controlled on the outer periphery of the electric clothes dryer main body 1 can be connected to this power feeding module. The power feeding module includes a number of rechargeable batteries 21221 and corresponding control circuit boards 21222. Further, a wireless charging module 21223 can also be provided between the power feeding module and the main body 1. When the electric clothes dryer is in the retracted state and the first end cap 212 approaches the main body 1, the rechargeable batteries 21221 can be charged through the wireless charging module 21223, thereby simplifying the wiring design between the power feeding module and the main body 1. The first inner cavity 2121 and the second inner cavity 2122 are arranged side by side vertically at the first end cap 212. In this embodiment, in order to facilitate the replacement of the rechargeable batteries 21221 in the power feeding module, the second inner cavity 2122 can be arranged near the lower edge of the first end cap 212 to reduce the space blockage of the second inner cavity 2122. Correspondingly, the first inner cavity 2121 is arranged above the second inner cavity 2122. The electrical control components in the first inner cavity 2121 are electrically connected to the power feeding module in the second inner cavity 2122 through wires. Connecting through wires can ensure the reliability of power feeding and control. Both the first inner cavity 2121 and the second inner cavity 2122 span the front ends of a pair of elastic telescopic tubes. Both the first inner cavity 2121 and the second inner cavity 2122 are longitudinally elongated shapes,

[0061] Further, first limiting members 2123 are respectively provided at the longitudinal ends of the first inner cavity 2121 and the second inner cavity 2122 for providing a plurality of limiting points or mounting positions. Refer to Figures 8 - 9, the first limiting member 2123 includes a cover plate 21231, a motor positioning groove 21232 protruding from the outer side surface of the cover plate 21231, and a cavity positioning groove 21233 protruding from the inner side surface of the cover plate 21231. Specifically, the size of the cover plate 21231 covers the ends of the first inner cavity 2121 and the second inner cavity 2122. The side surfaces in contact with the first inner cavity 2121 and the second inner cavity 2122 are defined as the inner side surfaces. There are two cavity positioning grooves 21233 arranged vertically on the inner side surface of the cover plate 21231, which respectively adapt to the cross-sectional profiles of the first inner cavity 2121 and the second inner cavity 2122, so that the cover plate 21231 can be nested at the edges of the first inner cavity 2121 and the second inner cavity 2122. The side surfaces opposite to the inner side surfaces of the cover plate 21231 are defined as the outer side surfaces. There is a semi-surrounding motor positioning groove 21232 on the outer side surface of the cover plate 21231. The inner side wall of the motor positioning groove 21232 adapts to the outer contour of the motor 224, and there is also a through hole at the bottom of the groove for the output shaft of the motor 224 to pass through, so that the motor 224 is connected to the reel 223 in the first inner cavity 2121, and the output shaft of the motor 224 can drive the reel 223 to rotate forward or backward to realize the winding or spreading of the soft drying member. Optionally, a brushless motor is adopted in this embodiment. Thus, the contour of the inner side wall of the motor positioning groove 21232 adapts to the outer contour of the brushless motor and is configured as a rectangle with approximately one-sided opening.

[0062] Further, an abutting area 21232a for abutting against the plug 2111 of the telescopic rod 211 is provided on the outer side wall of the motor positioning groove 21232. The abutting area 21232a is the groove wall between the motor 224 and the telescopic rod 211. A screw 21111 is inserted into the plug 2111 of the present application from the outside for fixing various parts connected to the plug 2111 (including the spring 2113, the outer sleeve 2115, and the housing 2116). Thus, the front end of the plug 2111 is the head of the screw 21111. Usually, the head of the screw has a standard three-dimensional geometric shape (hemispherical, cylindrical, hexagonal columnar, etc.). To fit the shape of the head of the screw 21111, the abutting area 21232a needs to be constructed with a groove capable of accommodating and clamping the head of the screw 21111 so that the head of the screw 21111 is not easily disengaged when abutting against the abutting area 21232a. In this embodiment, the staggered angle between the plug 2111 and the motor positioning groove 21232 is approximately 135°. A screw positioning post 21232b protruding relative to its outer side wall is provided in the motor positioning groove 21232. The axis of the screw positioning post 21232b is perpendicular to the axis of the screw 21111 of the plug 2111. The screw positioning post 21232b is integrally formed with the motor positioning groove 21232. Thus, a concave structure corresponding to the head of the screw 21111 of the plug 2111 is formed in the abutting area 21232a of the motor positioning groove 21232. This concave structure has a certain generality and can fit the heads of various common screws. Further, a connecting member for fixedly connecting or detachably connecting the plug 2111 and the first limiting member 2123 may be provided in the abutting area 21232a to further enhance the abutting stability between the two. More screw positioning posts 21232b may also be provided in the motor positioning groove 21232 to cooperate with the screw positioning posts 21232b in the abutting area 21232a to achieve the encapsulation and fixation of the motor 224.

[0063] According to the drying assembly integrated in the electric drying rack, other inner cavities may be provided in the first end cap 212, and may be arranged at any position above, below, or beside the first inner cavity 2121 and the second inner cavity 2122. In order to highlight the decorative function of the first end cap 212, an independent decorative plate may be provided on the outer surface of the first end cap 212 to cover each inner cavity arranged in a divided area.

[0064] Reference Figure 2 and 9, the soft drying part of the present application adopts mesh 22. The mesh 22 is laid in the drying net frame 21, and the mesh 22 is provided with a rolled edge 221 and a spread edge 222, wherein the rolled edge 221 of the mesh 22 is rolled in the first end cover 212, specifically rolled in the first inner cavity 2121, through a reel 223, and the two ends of the reel 223 are respectively fixed in the first limiter 2123, and at least one end of the reel 223 is controlled by a motor 224 fixed in the first limiter 2123 to rotate forward or reverse; the spread edge 222 of the mesh 22 is fixed in the positioning rod 213. The mesh 22, as the drying and supporting structure of the electric telescopic frame 2, is preferably made of a waterproof, weather-resistant, bending-resistant, and stretch-resistant material to a certain extent, and can be made of rust-proof steel wire mesh, polyethylene mesh, polypropylene mesh, nylon mesh or polyester mesh. In the present application, the horizontal plane of the mesh 22 in the spread state is slightly lower than the upper edge of the pair of telescopic rods 211, or even lower than the lower edge thereof, so that the drying frame 21 can serve as a barrier around the mesh 22. The reel 223 includes an axis core, and optionally may also include a coil spring wound around the axis core, and the coil spring is arranged so that the mesh 22 always remains in a state of being rolled up toward the axis core, so that the mesh 22 can be automatically rolled up without or with weak external force.

[0065] Combining the spreading method of the mesh 22 and the supporting method of the pair of telescopic rods 211, it can be known that the telescopic principle of the drying net of the present application is as follows:

[0066] The pair of telescopic rods 211 maintain a moderate compression state, accumulating reverse outward force, so that the first end cover 212 is continuously pressed by the pair of telescopic rods 211. Since the pair of telescopic rods 211 can maintain a horizontal state, the entire drying net frame 21 can remain horizontal within the telescopic range of the telescopic rods 211. The rolled edge 221 and the spread edge 222 of the net cloth 22 are fixed respectively, and are kept in a taut state under the pressing action of the pair of telescopic rods 211, thereby providing a certain load capacity, which can be used for drying items (clothing or food) within a certain weight range. When the reel 223 drives the rolled edge 221 of the net cloth 22 to be released in a forward rotation, the distance between the rolled edge 221 and the spread edge 222 increases, and the pressure on the pair of telescopic rods 211 is gradually released. The pressing action of the pair of telescopic rods 211 on the first end cover 212 becomes dominant, and the first end cover 212 gradually moves forward under the combined action of the pushing force of the telescopic rods 211 and the pulling force of the net cloth 22, and the electric telescopic frame 2 is unfolded. When the reel 223 drives the reeling edge 221 of the mesh 22 to reel, the distance between the reeling edge 221 and the spreading edge 222 decreases, the pressure on the pair of telescopic rods 211 gradually increases, the reeling effect of the mesh 22 becomes dominant, and the first end cover 212 gradually translates backward under the combined effect of the pushing force of the telescopic rod 211 and the pulling force of the mesh 22, and the electric telescopic frame 2 is retracted. The forward and reverse rotation of the reel 223 are relative, and do not limit the forward rotation direction or the reverse rotation direction.

[0067] In another embodiment (not shown), when an electric control assembly is provided in the skeleton rod, the reel 223 does not need to be provided with an electric control assembly, nor does it need to be provided with a spring 2113 in the skeleton rod, and the expansion and storage of the drying net frame 21 can be directly controlled by the skeleton rod. In a possible implementation, an electric control assembly is provided inside the overlapping section of the mutually interlocking rods of the skeleton rods, so that the mutually interlocking skeleton rods can move toward or away from each other to achieve the extension and contraction of the telescopic rod 211. Optionally, the electric control assembly includes a driving member and a transmission member, the driving member can be a suitable motor, and the transmission member includes a guide rail and a sliding member respectively connected to the coaxially sleeved skeleton rods, so that the sliding member moves along the guide rail under the drive of the driving member. When the telescopic rod 211 is composed of an inner sleeve 2114 and an outer sleeve 2115, the transmission member is arranged in the gap between the inner sleeve 2114 and the outer sleeve 2115, and the overlapping range of the two is used as the travel control area, that is, a guide rail is arranged between the shortest overlapping section mark position and the longest overlapping section mark position to limit the travel range of the sliding member, and the driving member transmits the driving force to the sliding member by setting a reasonable transmission structure. When the telescopic rod 211 is composed of a housing 2116 and a fixed rod 231, the configuration of the electric control component is the same as before, and no further description is given.

[0068] refer to Figure 1 , 3 ~7, the electric telescopic frame 2 of this embodiment also includes a fixed frame 23, the fixed frame 23 includes a pair of fixed rods 231 coaxially nested with the telescopic rod 211, the inner cavity size of the fixed rod 231 is larger than the outer contour size of the telescopic rod 211, specifically, the inner cavity size of the fixed rod 231 is larger than the outer contour size of the outer shell 2116 of the telescopic rod 211, so that the telescopic rod 211 can be stored as a whole inside the fixed rod 231, thereby realizing the concealed storage of the electric telescopic frame 2. Further, the sleeve 2118 of the telescopic rod 211 is installed at the end of the fixed rod 231, and the fixed plate 21182 of the sleeve 2118 extends downward. In this embodiment, the sleeve 2118 is used to fill the gap between the outer shell 2116 of the telescopic rod 211 and the fixed rod 231. The pad 2117 installed adjacent to the sleeve 2118 is configured in the fixed sleeve. The pad 2117 can extend the filling range between the outer shell 2116 of the telescopic rod 211 and the fixed rod 231, thereby reducing the shaking and the noise generated when the electric telescopic frame 2 is spread or stored. The fixed plate 21182 of the sleeve 2118 is also used as a resistance structure for the electric telescopic frame 2 to be stored in place, and can be used as the moving end point of the first end cover 212 to be stored inwardly. A sensor can also be set on the fixed plate 21182 to realize intelligent control of the electric telescopic frame 2, including but not limited to realizing the control of the spread length of the electric telescopic frame 2, or judging the load degree of the electric telescopic frame 2.

[0069] The fixed rod 231 can be made of a material with higher durability, providing a stable fulcrum for the extension and storage of the electric telescopic rack 2; this fixed rod 231 also serves as the fixed rod 231 for all drying components and is part of the main drying rack 4. The drying rods with other functions can be configured based on this pair of fixed rods 231. For example, the quilt drying rod can be arranged above or below the fixed rod 231. The base 2112 of the aforementioned telescopic rod 211 can be fixed inside the fixed rod 231, realizing an assembly method in which two telescopic rods 211 are coaxially accommodated in the opposite direction by one fixed rod 231. Preferably, the base 2112 is installed at the axisymmetric position of the fixed rod 231.

[0070] Furthermore, the positioning rod 213 of this embodiment is orthogonally fixed between a pair of fixed rods 231. The pair of positioning rods 213 and the pair of fixed rods 231 form the basic framework of the main drying rack 4 and are connected to the positioning rod 213 and the main unit 1 through the scissors frame 5 or the steel wire rope to form a retractable drying component. Refer to Figure 1 、 10, 11. In the presence of the fixed rod 231, the positioning rod 213 is directly connected to the fixed rod 231. At this time, the positioning rod 213 includes transition ends 2132 provided at both ends thereof. The transition end 2132 includes a vertically arranged fixing plate 21321, an upper avoidance groove 21322 that is laterally retracted relative to the upper edge of the fixing plate 21321, a lower avoidance groove 21323 that is laterally retracted relative to the lower edge of the fixing plate 21321, a protective cover 21324 that extends laterally from the top end of the upper avoidance groove 21322, upper stop strips 21325 that extend downward from both side edges of the upper avoidance groove 21322, lower stop strips 21326 that extend upward from both side edges of the lower avoidance groove 21323, and a reinforcing back plate 21327 that extends vertically downward from the bottom of the upper avoidance groove 21322 to the bottom of the lower avoidance groove 21323. Further, the positioning rod 213 abuts against the fixed rod 231 through the fixing plate 21321 and is connected by bolts. The retraction depth and shape of the upper avoidance groove 21322 and the lower avoidance groove 21323 are related to the structure of the fixed rod 231. In this embodiment, an extension plate with a plurality of hanging holes extends downward from the body of the fixed rod 231, thereby forming a contour with protruding upper and lower edges on the inner side of the fixed rod 231. The fixing plate 21321, the upper avoidance groove 21322, and the lower avoidance groove 21323 of the transition end 2132 are adapted to the contour on the inner side of the fixed rod 231. The protective cover 21324, the upper stop strips 21325, the lower stop strips 21326, and the reinforcing back plate 21327 are all configured to meet the usage requirements of the electric clothes dryer. In other embodiments, the specific shapes and structures of the protective cover 21324, the upper stop strips 21325, the lower stop strips 21326, and the reinforcing back plate 21327 can be adjusted adaptively. In other possible embodiments, in the absence of the fixed rod 231, the positioning rod 213 can be directly connected to the housing 2116 of the telescopic rod 211. At this time, the positioning rod 213 can translate following the translation of the housing 2116, and the structures of the upper avoidance groove 21322 and the lower avoidance groove 21323 can be modified or omitted according to actual situations. The positioning rod 213 of this embodiment further includes a first card slot 2131. The first card slot 2131 is provided on the side of the positioning rod 213 facing the mesh 22 for fixing the spreading edge 222 of the mesh 22. The connection between the spreading edge 222 of the mesh 22 and the first card slot 2131 can be detachable, but it should be ensured that when the mesh 22 is pulled in the direction of the first end cap 212 in the connected state, the spreading edge 222 of the mesh 22 cannot be disengaged from the first card slot 2131. In this embodiment, the spreading edge 222 of the mesh 22 is sealed with a rubber strip. The rubber strip is nested in the first card slot 2131, and at least two pins are vertically inserted into the first card slot 2131 and abutted against the rubber strip to fix the rubber strip.

[0071] Optionally, the positioning rod 213 further includes an inner groove body 2133 for installing the scissor frame 5. Thus, the first card slot 2131 and the transition end 2132 are arranged outside the inner groove body 2133. Based on the inner groove body 2133, other installation structures or positioning structures can also be arranged on the positioning rod 213 to meet the assembly requirements of the drying component. If the positioning rod 213 is connected to the main body 1 by a steel wire rope, the positioning rod 213 with the first card slot 2131 can be integrally arranged. If the installation requirements of the two ends of the positioning rod 213 with the fixed rod 231 or the telescopic rod 211 are relatively simple, the transition end 2132 and the positioning rod 213 can also be integrally arranged.

[0072] Thus, it can be seen that the positioning rod 213 is not only a connecting structure in the middle of a pair of telescopic rods 211, forming the drying net frame 21, but also the connection center of the entire drying component.

[0073] In other embodiments, a telescopic quilt drying rod 3 is arranged above the electric telescopic frame 2. The telescopic quilt drying rod 3 includes an extension rod 32 that telescopically extends in the same direction as the electric telescopic frame 2, and a second end cap 31 is arranged at the end of the extension rod 32. In one possible implementation, the second end cap 31 and the first end cap 212 are integrally formed. When the electric telescopic frame 2 is unfolded, it will drive the telescopic quilt drying rod 3 to be horizontally unfolded synchronously. The extension rod 32 of the telescopic quilt drying rod 3 and the telescopic rod 211 are arranged side by side vertically. The advantage of such a setting is that it can provide a deeper accommodation space for the electric telescopic frame 2, and the enclosure of the electric telescopic frame 2 is equivalent to being heightened by the extension rod 32. The synchronous unfolding and retracting of the telescopic quilt drying rod 3 and the electric telescopic frame 2 is beneficial to keeping the telescopic quilt drying rod 3 visually hidden before it is unfolded and used. In another possible implementation, the second end cap 31 and the first end cap 212 are detachably arranged. The second end cap 31 or the first end cap 212 can be provided with a connecting member for selectively connecting the first end cap 212 and the second end cap 31. The connecting member can be implemented in any form of a pin connection assembly, a snap connection assembly or a magnetic attraction assembly. The advantage of such a setting is that in the case where only the electric telescopic frame 2 needs to be used, the electric telescopic frame 2 can be unfolded separately, reducing the operation burden of the motor 224. Further, the connection or disconnection of the connecting member can be manually controlled or an electric control module can be configured to achieve intelligent control. The installation position of the connecting member can be selected to be arranged on the front of the end cap, the side of the end cap or the gap between the first end cap 212 and the second end cap 31 that face each other.

[0074] In summary, for the electric telescopic rack of the present application, it includes a sunning net frame and a soft sunning member laid within the sunning net frame. The sunning net frame includes a pair of parallel telescopic rods, a first end cap connected to the front ends of the telescopic rods, and a positioning rod connected to the middle parts of the telescopic rods. The winding edge of the soft sunning member is wound in the first end cap through a reel, and the spreading edge of the soft sunning member is detachably fixed in the positioning rod. The telescopic rod includes a framework rod member. The reel or the framework rod member is configured with an electric control assembly for controlling the expansion and contraction of the sunning net frame. The present application also provides an electric clothes dryer, which includes a main body and a sunning assembly. Among them, the sunning assembly includes the electric telescopic rack as described above. For the electric telescopic rack of the present application, the provided telescopic rod not only provides a compression space for the storage of the sunning net, but also provides a strong pressure itself, which can play a role in pushing against the first end cap in the opposite direction to achieve the overall support of the sunning net frame, so that no additional bottom support is required during the process of spreading the net cloth, and the telescopic rod provides an external force for tensioning the net cloth.
