TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying, in particular to a clothes drying main machine and a clothes drying machine. BACKGROUND

[0002] The clothes drying main machine can be generally divided into a folding type and a wardrobe type. The folding type clothes drying main machine has the characteristics of convenient storage and adaptability to various scenes, but its drying capacity is usually limited. Therefore, the folding type clothes drying main machine is usually designed as a double folding rotary structure to increase the drying capacity. However, due to the design of internal wiring of the clothes drying main machine, problems such as wire clamping, wire hanging, wire cutting or wire stretching are prone to occur during rotation, thereby affecting the normal use of the clothes drying machine. CONTENT OF THE UTILITY MODEL

[0003] Therefore, it is necessary to provide a clothes drying main machine and a clothes drying machine to effectively improve the problems such as wire clamping, wire hanging, wire cutting or wire stretching during rotation and ensure the normal use of the clothes drying machine.

[0004] A clothes drying main machine, comprising: a first shell; a second shell rotationally connected with the second shell; and heating bodies respectively arranged in the first shell and the second shell; wherein the clothes drying main machine further comprises an electrical connecting member, the electrical connecting member comprises a flexible part and first and second connecting parts respectively connected with two ends of the flexible part, the flexible part is arranged in the first shell and can elastically stretch and contract between the first and second connecting parts, the first connecting part is respectively inserted into and fixed in the second shell, the second connecting part is fixed in the first shell, and the first and second connecting parts are respectively electrically connected with the two heating bodies.

[0005] The clothes drying main machine described above connects the heating bodies in the first and second shells through the electrical connecting member, so that the two heating bodies are effectively electrically connected. Since the electrical connecting member comprises the flexible part and the first and second connecting parts arranged at two ends of the flexible part, and the first connecting part is fixed in the second shell and the second connecting part is fixed in the first shell, when the first shell is rotated to be unfolded or folded relative to the second shell, the second connecting part rotates together with the first shell, and the first connecting part remains stationary relative to the second shell, and at this time, the second connecting part moves relative to the first connecting part. Since the flexible part can stretch and contract between the first and second connecting parts, the stretching and contracting performance of the flexible part can effectively improve the problems such as wire clamping, wire hanging, wire cutting or wire stretching of the electrical connecting member when the clothes drying main machine is unfolded or folded, and ensure the normal use of the clothes drying machine.

[0006] In some embodiments, the telescopic part comprises a spiral part spirally extending around a first axis thereof, and the first and second connecting parts are respectively connected to two ends of the spiral part.

[0007] In some embodiments, the clothes drying main machine further comprises a constraint part arranged in the first housing and configured to constrain the telescopic path of the spiral part.

[0008] In some embodiments, the spiral part spirally extends around a first axis thereof and forms a constraint channel extending along the first axis inside the spiral part, and the constraint part is arranged in the constraint channel.

[0009] In some embodiments, the constraint part is configured as a structure extending around the periphery of the first axis, and two ends of the constraint part respectively extend out of the two ends of the spiral part when the clothes drying main machine is in the unfolded state.

[0010] In some embodiments, the clothes drying main machine further comprises a buckle member provided with a clamping groove configured to clamp the constraint part, and the buckle member is clamped on the inner wall of the first housing.

[0011] In some embodiments, the buckle member comprises a plurality of buckle members, at least two of which are arranged on two sides of the spiral part and are configured to clamp the constraint part on the inner wall of the first housing.

[0012] In some embodiments, the clothes drying main machine further comprises a limiting part and a fixing seat arranged in the first housing, and the limiting part is configured to fix the second connecting part on the fixing seat.

[0013] In some embodiments, the first housing comprises a first housing body and a first shaft housing arranged on the first housing body, the second housing comprises a second housing body and a second shaft housing arranged on the second housing body, the first shaft housing and the second shaft housing are rotationally connected, and the first housing body and the second housing body each have the heating body; the telescopic part is arranged in the first shaft housing, the first connecting part passes through the first shaft housing and is fixed in the second shaft housing, and the second connecting part is fixed in the first shaft housing or the first housing body.

[0014] In some embodiments, the second shaft housing comprises an end cover part and an enclosure part having a second axis, the end cover part is arranged at one end of the enclosure part along the direction of the second axis and faces the first shaft housing, the first connecting part sequentially passes through the first shaft housing and the end cover part and extends into the enclosure part, and the first connecting part is fixed on the end cover part.

[0015] A clothes dryer, comprising the clothes dryer main machine of any one of the above.

[0016] The clothes dryer described above, using the clothes dryer main machine described above, connects the heating bodies in the first shell and the second shell through the electrical connector, so that the two heating bodies are effectively electrically connected. Since the electrical connector includes the telescopic part and the first connecting part and the second connecting part provided at both ends of the telescopic part, and the first connecting part is fixed in the second shell, and the second connecting part is fixed in the first shell. In this way, when the first shell is unfolded or folded relative to the second shell, the second connecting part rotates with the first shell, and the first connecting part remains stationary with the second shell, and at this time the second connecting part moves relative to the first connecting part. Again, since the telescopic part can be telescoped between the first connecting part and the second connecting part, the telescopic performance of the telescopic part itself can effectively improve the problems of wire clamping, wire hanging, wire cutting or wire stretching of the electrical connector when the clothes dryer main machine is unfolded or folded, and ensure normal use of the clothes dryer.

[0034] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on another element or there can be a middle element. If an element is considered to be "connected" to another element, it can be directly connected to another element or there can be a middle element.

[0035] Clothes dryers are generally divided into folding and wardrobe types. Folding dryers are convenient to store and adaptable to various scenarios, but their drying capacity is usually limited. Therefore, folding dryers are typically designed with a double-folding rotating structure to increase the amount of clothes that can be dried. Double-folding dryers have two air ducts, one for forward and one for reverse airflow. Each duct contains a heating element, and both heating elements require electrical connection. The two air ducts are installed in the left and right side housings respectively; therefore, the heating element cables need to pass through both housings.

[0036] When one shell rotates relative to the other, the wires inside the shell will be stretched or contracted. However, this process can lead to problems such as wire entanglement, snagging, cutting, or tautness. For example, when the two shells rotate and unfold, the wiring path between the heating elements shortens, causing the wires to contract and become loose, making them prone to entanglement, snagging, or cutting with surrounding structures. When the two shells rotate and overlap, the wiring path between the heating elements increases, causing the wires to stretch and become taut, making them prone to snapping.

[0037] Based on this, please refer to Figures 1 to 3 This application provides a clothes dryer 100, which includes a first housing 1a, a second housing 1b, heating elements 90, and an electrical connector 30. The second housing 1b is rotatably connected to the first housing 1a, and the heating elements 90 are respectively disposed in the first housing 1a and the second housing 1b. The clothes dryer 100 further includes the electrical connector 30, which includes a telescopic part 31 and a first connecting part 32 and a second connecting part 33 respectively connected to the two ends of the telescopic part 31. The telescopic part 31 is disposed in the first housing 1a and can elastically extend and retract between the first connecting part 32 and the second connecting part 33. The first connecting part 32 is respectively inserted into and fixed in the second housing 1b, and the second connecting part 33 is fixed in the first housing 1a. The first connecting part 32 and the second connecting part 33 are respectively electrically connected to the two heating elements 90.

[0038] The above-described clothes drying main machine 100 connects the heating bodies 90 in the first shell 1a and the second shell 1b through the electrical connecting member 30, so that the two heating bodies 90 are effectively electrically connected. Since the electrical connecting member 30 includes the stretchable part 31 and the first connecting part 32 and the second connecting part 33 arranged at both ends of the stretchable part 31, the first connecting part 32 is fixed in the second shell 1b, and the second connecting part 33 is fixed in the first shell 1a. In this way, when the first shell 1a rotates to unfold or fold relative to the second shell 1b, the second connecting part 33 rotates together with the first shell 1a, and the first connecting part 32 remains stationary relative to the second shell 1b, at which time the second connecting part 33 moves relative to the first connecting part 32. Since the stretchable part 31 can stretch and contract between the first connecting part 32 and the second connecting part 33, the stretchable part 31 itself can effectively improve the problems of pinching, hanging, cutting or stretching of the wire when the clothes drying main machine 100 rotates to unfold or fold, and ensure normal use of the clothes drying machine.

[0039] It should be noted that the stretchable part 31 can elastically stretch and contract between the first connecting part 32 and the second connecting part 33, and when the first shell 1a rotates to fold relative to the second shell 1b, the second connecting part 33 rotates together with the first shell 1a, and the first connecting part 32 remains stationary relative to the second shell 1b, at which time the second connecting part 33 moves relative to the first connecting part 32. As the first shell 1a and the second shell 1b are completely folded, the distance between the first connecting part 32 and the second connecting part 33 increases, so that the stretchable part 31 is stretched. Since the stretchable part 31 has the stretchable performance, the risk of being broken can be effectively avoided. When the first shell 1a rotates to unfold relative to the second shell 1b, the second connecting part 33 also moves relative to the first connecting part 32. As the first shell 1a and the second shell 1b are completely unfolded, the distance between the first connecting part 32 and the second connecting part 33 decreases, so that the stretchable part 31 elastically retracts, avoiding the stretchable part 31 being in a relaxed state due to contraction, and effectively improving the problems of pinching, hanging, cutting and the like of the wire with the surrounding structure when rotating to unfold.

[0040] The stretchable part 31 elastically stretches and contracts between the first connecting part 32 and the second connecting part 33, and its implementation has many ways, such as: the stretchable part 31 is designed in a spiral structure; or the stretchable part 31 is designed in a wave-like zigzag shape.

[0041] It should be noted that the first shell 1a and the second shell 1b are rotationally connected, so that the first shell 1a can be rotationally folded or unfolded from the second shell 1b. When the first shell 1a and the second shell 1b are rotationally folded, the clothes drying main machine 100 can be conveniently stored. When the first shell 1a and the second shell 1b are rotationally unfolded, the clothes drying main machine 100 can conveniently output heat outward to perform the clothes drying operation. The connection mode between the first shell 1a and the second shell 1b can be various, as long as it can meet the rotationally folding or unfolding of the first shell 1a and the second shell 1b.

[0042] Specifically, in some embodiments, referring to Figure 1 and Figure 2 , the first shell 1a can include a first shell body 10 and a first shaft shell 11 arranged on the first shell body 10, and the second shell 1b can include a second shell body 20 and a second shaft shell 21 arranged on the second shell body 20. One end of the first shaft shell 11 rotationally cooperates with one end of the second shaft shell 21, such as that one end of the first shaft shell 11 is rotationally sleeved outside one end of the second shaft shell 21. In this way, the first shell body 10 and the second shell body 20 can be rotationally folded or unfolded through the first shaft shell 11 and the second shaft shell 21.

[0043] Optionally, the connection mode of the first connecting part 32 in the second shell 1b can be various, such as but not limited to bolt connection, clamping, binding, etc. At the same time, the connection mode of the second connecting part 33 in the first shell 1a can also be various, such as but not limited to bolt connection, clamping, binding, etc.

[0044] In addition, in order to better elastically retract the telescopic part 31 when the clothes drying main machine 100 is rotationally unfolded, the telescopic part 31 is in a stretched state when the clothes drying main machine 100 is in a folded state, and the telescopic part 31 is in an initial state when the clothes drying main machine 100 is in an unfolded state.

[0045] Further, referring to Figure 1 and Figure 2 , the telescopic part 31 includes a spiral part 3a, the spiral part 3a spirally extends around a first axis 34 thereof, and the first connecting part 32 and the second connecting part 33 are respectively connected to two ends of the spiral part 3a. It can be known that the telescopic part 31 is designed as the spiral part 3a, which facilitates the elastic stretching of the spiral part 3a when the clothes drying main machine 100 is rotationally folded or unfolded, effectively matches the rotation between the first shell 1a and the second shell 1b, ensures that the structure of the electrical connecting part 30 of the clothes drying main machine 100 is more stable, avoids problems such as wire clamping, wire hanging, wire cutting or wire stretching, and improves the use stability of the clothes drying main machine 100.

[0046] It should be noted that when the first shell 1a is folded relative to the second shell 1b, the first shell 1a drives the second connecting part 33 to move, stretches the spiral part 3a, and avoids the risk of breaking. When the first shell 1a is unfolded relative to the second shell 1b, the first shell 1a drives the second connecting part 33 to move, extrudes the spiral part 3a, and makes it elastically shrink to restore its initial state, thereby avoiding the problem of the spiral part 3a being loose during folding and causing wire clamping, wire hanging or wire cutting.

[0047] The number of the spiral part 3a can be one or multiple. When the spiral part 3a is multiple, all the spiral parts 3a can be connected in sequence, the first connecting part 32 is connected with the spiral part 3a at one end, and the second connecting part 33 is connected with the spiral part 3a at the other end.

[0048] In some embodiments, referring to Figure 6 and Figure 7 The drying host 100 further comprises a constraint part 35 arranged in the first shell 1a and used for constraining the extension and contraction path of the spiral part 3a. Thus, the constraint part 35 is introduced to make the spiral part 3a elastically extend and contract in a specified path, thereby standardizing the extension and contraction path of the spiral part 3a and avoiding the influence of the deviation of the spiral part 3a on the rotation of the drying host 100.

[0049] It should be noted that the constraint part 35 refers to a structure that can guide the extension and contraction of the spiral part 3a, so that the extension and contraction path of the spiral part 3a is in a predetermined track. The constraint part 35 can be designed as a pipe structure, which is sleeved outside the spiral part 3a, or as a rod structure, which is arranged inside the spiral part 3a, etc.

[0050] Meanwhile, the constraint part 35 can be fixed in the first shell 1a in various ways, such as, but not limited to, bolt connection, clamping, binding, bonding, etc. In addition, when the first shell 1a comprises a first shell body 10 and a first shaft shell 11 arranged on the first shell body 10, the constraint part 35 can be arranged on the first shell body 10 or the first shaft shell 11.

[0051] Further, referring to Figure 5 and Figure 6, the spiral part 3a spirally extends around the first axis 34 of itself and forms a constraint channel 311 extending along the first axis 34 inside itself, and the constraint part 35 is threaded in the constraint channel 311. Thus, the spiral part 3a spirals around the first axis 34 and forms the constraint channel 311 inside it. At this time, the constraint part 35 is threaded in the constraint channel 311, so that the spiral part 3a is sleeved on the constraint part 35. When the first shell 1a is folded or unfolded relative to the second shell 1b, the spiral part 3a elastically extends or contracts on the constraint part 35, so that the spiral part 3a extends and contracts along the constraint part 35, ensuring that the extension and contraction path of the spiral part 3a remains stable, avoiding the occurrence of deviation to cause unstable rotation of the clothes drying main machine 100.

[0052] It should be noted that the size of the constraint channel 311 can be matched with the size of the constraint part 35, for example: when the constraint channel 311 is a cylindrical channel, the inner diameter of the constraint channel 311 can be equal to or slightly larger than the diameter of the constraint part 35, so that the gap between the constraint channel 311 and the constraint part 35 can be reduced, so that the spiral part 3a can be elastically extended and contracted on the outer surface of the constraint part 35, which is conducive to improving the stability of rotation.

[0053] In some embodiments, please refer to Figure 6 With Figure 7 , the constraint part 35 is configured as a structure extending around the outer periphery of the first axis 34, and the two ends of the constraint part 35 respectively correspond to the two ends of the spiral part 3a extending out when the clothes drying main machine 100 is in the unfolded state. Thus, the constraint part 35 is configured as a structure extending around the outer periphery of the first axis 34, so that the spiral part 3a can also extend and contract around the outer periphery of the first axis 34, which is conducive to more stable rotation of the clothes drying main machine 100.

[0054] It should be noted that since the spiral part 3a will be stretched when the clothes drying main machine 100 is folded, in order to ensure that the stretched spiral part 3a can also be sleeved on the constraint part 35, the length of the constraint part 35 around the outer periphery of the first axis 34 can be increased as much as possible, for example: the constraint part 35 extends annularly around the outer periphery of the first axis 34 in the first shell 1a, and the corresponding central angle can be greater than 180°, 270°, etc.; or, the constraint part 35 extends annularly around the outer periphery of the first axis 34 by 360° in the first shell 1a. At the same time, when the constraint part 35 is an arc structure, in order to make the spiral part 3a better sleeved on the constraint part 35, the bending radius of the spiral part 3a around the first axis 34 should be greater than the radius of the constraint part 35.

[0055] In addition, when the clothes drying host 100 is in the unfolded state, the first shell 1a is rotated and opened relative to the second shell 1b, at this time, the two ends of the constraint component 35 are respectively beyond the two ends of the spiral part 3a, so that the spiral part 3a can be better stretched along the surface of the constraint component 35 when being stretched, and the rotation stability of the clothes drying host 100 is improved.

[0056] Further, please refer to Figure 8 The clothes drying host 100 further comprises a buckle component 40, the buckle component 40 is provided with a clamping groove 41, the clamping groove 41 is used for clamping the constraint component 35, and the buckle component 40 is clamped on the inner wall of the first shell 1a. In this way, the constraint component 35 is stably arranged in the first shell 1a by the buckle component 40, so as to ensure the stable stretching of the spiral part 3a. At the same time, the buckle component 40 also facilitates the installation and fixation of the constraint component 35, which is beneficial to improve the assembly efficiency of the clothes drying host 100. In addition, the clamping groove 41 is arranged on the buckle component 40, which facilitates the stable combination of the constraint component 35 and the buckle component 40, avoids the deviation of the constraint component 35 from the buckle component 40, and causes the instability of the structure.

[0057] It should be noted that the shape of the clamping groove 41 can be consistent with the outer surface of the constraint component 35, so that the groove wall of the clamping groove 41 can be stably attached to the outer surface of the constraint component 35, and the stability of the installation of the constraint component 35 is further improved.

[0058] At the same time, the clamping mode of the buckle component 40 on the inner wall of the first shell 1a has various modes, for example: the buckle component 40 is provided with a groove-shaped or hole-shaped structure, and the inner wall of the first shell 1a is provided with a protruding structure matched with the groove-shaped or hole-shaped structure; or the buckle component 40 is provided with a protruding structure, and the inner wall of the first shell 1a is provided with a groove-shaped or hole-shaped structure matched with the protruding structure.

[0059] Specifically, in some embodiments, please refer to Figure 9 The buckle component 40 comprises a main body part 42 and a clamping part 43 arranged on the main body part 42, a clamping hole 44 is formed between the clamping part 43 and the main body part 42, and the inner wall of the first shell 1a is provided with a fixing column 111 clamped into the clamping hole 44. At the same time, the number of clamping parts 43 can be one or more, for example: the clamping part 43 and the fixing column 111 are two, the two clamping parts 43 are arranged on the two sides of the main body part 42, and the clamping hole 44 is formed between each clamping part 43 and the main body part 42. The fixing column 111 is clamped into the clamping hole 44 one by one.

[0060] In some embodiments, please refer to Figure 8, the buckle 40 includes a plurality of, at least two buckles 40 are located on both sides of the spiral part 3a, and are used for clamping the constraint part 35 on the inner wall of the first shell 1a. Through the plurality of buckles 40, the constraint part 35 is more stably installed on the inner wall of the first shell 1a. At the same time, the at least two buckles 40 are arranged on both sides of the spiral part 3a, so that the fixation of the buckle 40 avoids interference with the expansion and contraction of the spiral part 3a, and ensures that the rotation of the clothes drying host 100 is more stable.

[0061] In some embodiments, please refer to Figure 10 , the clothes drying host 100 further comprises a limiting part 50 and a fixing seat 51, the fixing seat 51 is arranged in the first shell 1a, and the limiting part 50 is used for fixing the second connecting part 33 on the fixing seat 51. In this way, through the cooperation of the limiting part 50 and the fixing seat 51, the second connecting part 33 is stably fixed in the first shell 1a.

[0062] It should be noted that when the first shell 1a includes the first shell body 10 and the first shaft shell 11 arranged on the first shell body 10, the fixing seat 51 can be arranged in the first shell body 10 or the first shaft shell 11.

[0063] Among them, the fixing mode of the fixing seat 51 in the first shell 1a has many kinds, such as: but not limited to bolt connection, clamping, riveting, welding, bonding and the like; or, the fixing seat 51 and the first shell 1a are integrated structure. At the same time, the connecting mode between the limiting part 50 and the fixing seat 51 can also be but not limited to bolt connection, clamping, riveting, welding, bonding and the like.

[0064] In some embodiments, please refer to Figure 10 , the fixing seat 51 is provided with a mounting hole 52, the limiting part 50 is fixed in the mounting hole 52, and the second connecting part 33 is fixed on the limiting part 50. Among them, the limiting part 50 can be but not limited to wire, strap, throat clamp and the like.
