Heat supply main machine and clothes dryer

Abstract

According to the heat supply main machine and the clothes dryer, an electric connecting piece is arranged in a second shaft shell, one end of the electric connecting piece extends into a first shaft shell and is fixed, and the other end of the electric connecting piece is fixed in the second shaft shell or a second shell body. Therefore, when the first shaft shell rotates relative to the second shaft shell, the two ends of the electric connecting piece can move relatively, so that the electric connecting piece is stretched or contracted. Because one end of the first shaft shell is convexly provided with the first guide part, and the first guide part extends along the periphery of the axis, one end of the electric connecting piece is limited by the first guide part when rotating along with the first shaft shell or the second shaft shell, so that the electric connecting piece is stretched or contracted on a certain track; the problems of wire clamping, wire hanging or wire cutting and the like between the electric connecting piece and the peripheral structure when the electric connecting piece is stretched or contracted are solved, and normal work of the heat supply main machine is guaranteed.

Nothing in this application should be construed as having a sole responsibility for the implementation.

[0035] With the rapid development of electrical technology, more and more heating hosts are gradually designed in the direction of convenient storage and large capacity. For example, taking the heating host as an example, in order to facilitate storage, the heating host is designed as a first part and a second part connected by rotation, and each of the first part and the second part has a heating body. When the first part and the second part are rotated and unfolded, each heating body can simultaneously output heat outward. In order to ensure that the two heating bodies work simultaneously, the two heating bodies need to be connected in the same circuit, which necessarily requires that the wire body is penetrated in the two first parts and the second parts to realize the electrical connection of the two heating bodies.

[0036] However, when the first part and the second part are relatively rotated and unfolded, the distance between the two heating bodies is relatively reduced, resulting in that the wire body is contracted and in a loose and curved state, which is easy to cause problems such as wire clamping, wire hanging and wire cutting with the surrounding structure, so that the heating host cannot be rotated to the open state, affecting the normal use of the heating host.

[0037] Based on this, please refer to Figures 1 to 4 , the application provides a kind of heating host 100, heating host 100 includes: first shell body 10, second shell body 20, heating body 70 and electrical connection 40.The first shell body 10 is equipped with the first shaft shell 11 with axis 111, the second shell body 20 is equipped with the second shaft shell 21, the first shaft shell 11 is penetrated in the direction of axis 111 one end of one end of second shaft shell 21, and both can rotate around axis 111.Heating body 70 is respectively arranged in first shell body 10 and second shell body 20, electrical connection 40 is arranged in second shaft shell 21, and one end thereof extends into and is fixed in first shaft shell 11, the other end is fixed in second shell body 20 or second shaft shell 21, electrical connection 40 is electrically connected to two heating bodies 70. Among them, the first shaft shell 11 is located on the end face of the second shaft shell 21 and is convexly provided with the first guide part 12, the first guide part 12 extends around the outer periphery of axis 111, and the side surface of the first guide part 12 away from axis 111 is used for limiting cooperation with electrical connection 40.

[0038] The heating host 100 described above is provided with the electric connecting piece 40 in the second shaft shell 21, and one end of the electric connecting piece 40 extends into the first shaft shell 11 and is fixed, and the other end is fixed in the second shaft shell 21 or the second shell body 20. In this way, when the first shaft shell 11 rotates relative to the second shaft shell 21, the two ends of the electric connecting piece 40 will move relatively, so that the electric connecting piece 40 is elongated or contracted. Since one end of the first shaft shell 11 is provided with the first guide part 12 extending along the outer periphery of the axis 111, when the one end of the electric connecting piece 40 rotates with the first shaft shell 11 or the second shaft shell 21, the electric connecting piece 40 will be limited by the first guide part 12, so that the elongation or contraction of the electric connecting piece 40 is carried out on a certain track, avoiding the problems of wire clamping, wire hanging or wire cutting between the electric connecting piece 40 and the surrounding structure when the electric connecting piece 40 is elongated or contracted, and ensuring the normal work of the heating host 100.

[0039] It should be noted that one end of the electric connecting piece 40 is fixed in the first shaft shell 11, and the other end is fixed in the second shaft shell 21 or the second shell body 20, so that the connecting wire body between the electric connecting piece 40 and the heating element will not be elongated or contracted when the heating host 100 rotates and overlaps or expands. Among them, the fixing mode of the electric connecting piece 40 in the first shaft shell 11 and the second shaft shell 21 or the second shell body 20 respectively has many kinds, such as: but not limited to binding, clamping, bolt connection, bonding and the like.

[0040] At the same time, when the first shell body 10 rotates relative to the second shell body 20 to overlap or expand, one end of the electric connecting piece 40 will rotate with the rotation, and the other end will remain relatively stationary with the second shell body 20. At this time, the two ends of the electric connecting piece 40 move relatively, so that the electric connecting piece 40 is elongated or contracted. Therefore, the first guide part 12 is provided on one end of the first shaft shell 11, and the side surface of the first guide part 12 away from the axis 111 is limited with the electric connecting piece 40, so that the extension and contraction of the electric connecting piece 40 is limited on the side of the first guide part 12 away from the first axis 111, the extension and contraction path of the electric connecting piece 40 is specified, the contact with the surrounding structure is reduced, and the problems of wire clamping, wire hanging or wire cutting are reduced.

[0041] In addition, the first guide part 12 is arranged on the end face of the first shaft shell 11 located in the second shaft shell 21 and extends around the outer periphery of the axis 111, and has an arc structure, so that the electric connecting piece 40 can better extend and contract under the guidance of the first guide part 12 when rotating to overlap or expand. Among them, the extension length of the first guide part 12 can be determined according to the rotation condition of the heating host 100; at the same time, the connection mode of the first guide part 12 on one end of the first shaft shell 11 also has many kinds, such as: but not limited to bolt connection, clamping, riveting, welding, pin connection and the like; or the first guide part 12 is an integrated structure with the first shaft shell 11.

[0042] It should be noted that the heating body 70 is located in the first shell body 10 and the second shell body 20 respectively, and is connected in the same circuit by the electric connecting piece 40, so that the two heating bodies 70 can work at the same time, so that the first shell body 10 and the second shell body 20 respectively send hot air outward. Among them, the heat supply host 100 of the embodiment can be applied in various electrical appliances, such as: can be but not limited to clothes dryer, indoor heating equipment, fan, etc.

[0043] Further, please refer to Figure 4 , both ends of the first guide part 12 are provided with the first scratch-proof part 13, and each first scratch-proof part 13 is bent and protruded to one side of the axis 111 relative to the first guide part 12. It can be seen that the first scratch-proof part 13 is arranged at both ends of the first guide part 12, so that when the electric connecting piece 40 stretches and contracts under the limitation of the first guide part 12, since the first scratch-proof part 13 is bent and protruded to one side of the axis 111, the part of the electric connecting piece 40 is prevented from being easily hung on one end of the first guide part 12, and the stable rotation of the heat supply host 100 is ensured.

[0044] Optionally, the connection between the first scratch-proof part 13 and the first guide part 12 can be but not limited to threaded connection, clamping, welding, etc.; the first scratch-proof part 13 and the first guide part 12 can also be designed as an integrated structure.

[0045] Further, please refer to Figure 5 and Figure 6 The heat supply host 100 further comprises a first air driving assembly 30 arranged in the second shaft shell 21, and the first air driving assembly 30 protrudes a second guide part 31 extending around the outer periphery of the axis 111 on one side face thereof facing the first shaft shell 11, and the side face of the second guide part 31 away from the axis 111 is used for limiting cooperation with the electric connecting piece 40. It can be seen that the second guide part 31 is arranged on one side face of the first air driving assembly 30, so that the electric connecting piece 40 has the first guide part 12 and the second guide part 31 on one side thereof facing the axis 111, thereby further ensuring that the stretching and contraction of the electric connecting piece 40 is more stable.

[0046] It should be noted that the first air driving assembly 30 refers to a component for blowing air flow into the first shell body 10, and in some embodiments, the first air driving assembly 30 comprises a first machine shell 35 and a fan wheel 36 arranged in the first machine shell 35. The first machine shell 35 is arranged in the second shaft shell 21, and the fan wheel 36 rotates under the drive of power to drive the air flow into the first shell body 10; and the second guide part 31 is arranged on the side face of the first machine shell 35 facing the first shaft shell 11.

[0047] It can be known that, since the first air driving assembly 30 is arranged in the second shaft shell 21, when the second shell body 20 rotates together with the second shaft shell 21, at least part of the first air driving assembly 30 also rotates together with the second shaft shell 21, for example, the first casing 35 of the first air driving assembly 30 rotates together with the second shaft shell 21, so that the second guide part 31 also rotates. In order to avoid structural interference between the second guide part 31 and the first guide part 12 when rotating, the second guide part 31 and the first guide part 12 can be distributed in the radial direction of the first shaft shell 11; or the second guide part 31 and the first guide part 12 are designed to be spaced apart along the outer periphery of the axis 111 in both the stacked state and the unfolded state; or the second guide part 31 and the first guide part 12 are kept apart in the direction of the axis 111 of the first shaft shell 11.

[0048] In addition, the second guide part 31 is arranged on one side of the first air driving assembly 30 and extends around the outer periphery of the axis 111, and has an arc-shaped structure, so that the electrical connecting piece 40 can better stretch and contract under the guidance of the second guide part 31 when rotating and stacking or unfolding. The extension length of the second guide part 31 can be determined according to the rotation of the heat supply host 100; at the same time, the connection mode of the second guide part 31 on one end of the first air driving assembly 30 also has many kinds, such as but not limited to bolt connection, clamping, riveting, welding, pin connection, etc.; or the second guide part 31 and the first air driving assembly 30 are integrated.

[0049] In some embodiments, please refer to Figure 7 With Figure 8 , the first guide part 12 is arranged close to the axis 111 relative to the second guide part 31, when the first shell body 10 and the second shell body 20 are relatively unfolded, the second guide part 31 is located on the side of the first guide part 12 away from the axis 111, when the first shell body 10 and the second shell body 20 are relatively stacked, the second guide part 31 and the first guide part 12 are respectively located on opposite sides of the axis 111. It can be known that, when the first shell body 10 and the second shell body 20 are relatively unfolded, the second guide part 31 is located on the side of the first guide part 12 away from the axis 111, and abuts with the electrical connecting piece 40 in position; when the first shell body 10 and the second shell body 20 are relatively stacked, the second guide part 31 turns away from the first guide part 12, and is distributed on opposite sides of the axis 111 with the first guide part 12, so that the first guide part 12 and the second guide part 31 can abut with the electrical connecting piece 40 in position, to ensure that the electrical connecting piece 40 stretched after the heat supply host 100 is stacked is stably located on the side of the first guide part 12 away from the axis 111, so as to ensure that the heat supply host 100 can recover to the unfolded state.

[0050] It should be noted that, since the first guide part 12 and the second guide part 31 are distributed in the radial direction of the first shaft shell 11, the projections of the first guide part 12 and the second guide part 31 on the axis 111 can at least partially overlap. In addition, in other embodiments, the second guide part 31 can also be located on the side of the first guide part 12 towards the axis 111.

[0051] In some embodiments, referring to Figure 8 , both ends of the second guide part 31 are provided with second scratch-preventing parts 32, and each second scratch-preventing part 32 is bent and protrudes towards the side of the second guide part 31 towards the axis 111. Therefore, by providing the second scratch-preventing parts 32 at both ends of the second guide part 31, when the electrical connecting part 40 is stretched and contracted under the limitation of the second guide part 31, since the second scratch-preventing parts 32 are bent and protrude towards the side of the second guide part 31 towards the axis 111, the part of the electrical connecting part 40 that is prone to being hung on one end of the second guide part 31 can be avoided, and the stable rotation of the heat supply host 100 can be ensured.

[0052] Optionally, the connection between the second scratch-preventing part 32 and the second guide part 31 can be, but is not limited to, threaded connection, clamping, welding, etc.; the second scratch-preventing part 32 and the second guide part 31 can also be designed as an integrated structure.

[0053] In some embodiments, referring to Figure 5 and Figure 6 , the two side surfaces of the first shaft shell 11 and the first air-moving assembly 30 facing each other correspondingly include the first limiting surface 14 and the second limiting surface 33, and the first limiting surface 14 and the second limiting surface 33 are arranged around the outer periphery of the axis 111, and the electrical connecting part 40 is at least partially located between the first limiting surface 14 and the second limiting surface 33. In this way, by the first limiting surface 14 and the second limiting surface 33, the left and right limiting of the electrical connecting part 40 is realized, and the stability of the electrical connecting part 40 during the rotation of the superposition or unfolding is ensured.

[0054] It should be noted that, when the first shaft shell 11 can be designed as a structure that can be disassembled into two parts, the first limiting surface 14 is formed by the two side surfaces of the two-part disassembled structure, so that the two side surfaces and the second limiting surface 33 can form the left and right limiting of the electrical connecting part 40.

[0055] In some embodiments, referring to Figure 5 and Figure 11The heat supply host 100 further comprises a fan 60, a second air driving assembly 50, a first air duct component 34 and a second air duct component 51. The second air driving assembly 50 is arranged in the first shaft shell 11. The fan 60 is used to drive the rotation of the air wheels 36 in the first air driving assembly 30 and the second air driving assembly 50. The first air duct component 34 is arranged in the second shell body 20 and is in communication with the first air driving assembly 30. The second air duct component 51 is arranged in the first shell body 10 and is in communication with the second air driving assembly 50. Thus, in operation, the fan 60 drives the rotation of the air wheels 36 in the first air driving assembly 30 and the second air driving assembly 50, and drives the air flow to enter the first air duct component 34 and the second air duct component 51 respectively. The air flow entering the first air duct component 34 and the second air duct component 51 is heated by the corresponding heating bodies 70, so that the air flow discharged from the first shell body 10 and the second shell body 20 is hot air.

[0056] It should be noted that the first air duct component 34 and the second air duct component 51 respectively refer to structures for guiding the air flow to the outside of the first shell body 10 and the second shell body 20. Therefore, in order to facilitate heating of the air flow, the heating bodies 70 can be arranged inside the first air duct component 34 and the second air duct component 51. Meanwhile, the second air driving assembly 50 comprises a second machine shell 52 and the air wheels 36 arranged in the second machine shell 52. The second machine shell 52 is arranged in the first shaft shell 11. The output end of the fan 60 extends into the first machine shell 35 and the second machine shell 52 respectively, and is connected with the two air wheels 36 respectively. In addition, in order to facilitate driving of the two air wheels 36, the fan 60 can be located between the first air driving assembly 30 and the second air driving assembly 50. At this time, the fan 60 can be arranged in the first shaft shell 11 or the second shaft shell 21.

[0057] In some embodiments, referring to Figure 3 and Figure 4 The second shaft shell 21 comprises a cylindrical portion 211 and an end cover portion 212 arranged at one end of the cylindrical portion 211. The first shaft shell 11 can be rotatably arranged in the end cover portion 212. The electrical connecting member 40 is at least partially located between the first guide portion 12 and the inner wall of the cylindrical portion 211. Thus, the inner wall of the cylindrical portion 211 is used as a peripheral track structure for limiting the electrical connecting member 40, so that the extension and contraction of the electrical connecting member 40 is stable between the first guide portion 12 and the cylindrical portion 211, and the stable operation of the heat supply host 100 is ensured.

[0058] It should be noted that the cylindrical portion 211 can be a cylindrical structure, which can be designed as a two-part structure that can be disassembled up and down. One part of the structure is arranged on the second shell body 20. Thus, the inner walls of the two parts can be used as peripheral track structures for limiting the electrical connecting member 40.

[0059] In addition, referring to Figure 4For the convenience of the rotation connection of the first shaft shell 11, the end cover part 212 is provided with a through hole, and the outer side of the first shaft shell 11 is provided with an annular groove 112. One end of the first shaft shell 11 penetrates through the through hole, and the inner wall of the through hole is clamped into the annular groove 112.

[0060] In some embodiments, referring to Figure 7 , Figure 8 and Figure 10 , the electrical connecting piece 40 includes a spiral part 41, a first connecting part 42 and a second connecting part 43 arranged at two ends of the spiral part 41. The spiral part 41 is arranged in the second shaft shell 21 and used for limiting cooperation with the first guide part 12. The first connecting part 42 penetrates into and is fixed in the first shaft shell 11. The second connecting part 43 is fixed in the second shaft shell 21 or the second shell main body 20.

[0061] Therefore, when the first shell main body 10 rotates to unfold or fold relative to the second shell main body 20, the second connecting part 43 rotates together with the second shell main body 20, and the first connecting part 42 remains stationary relative to the second shell main body 20. At this time, the second connecting part 43 moves relative to the first connecting part 42. Since the spiral part 41 can be elastically stretched and contracted between the first connecting part 42 and the second connecting part 43, the stretching and contracting performance of the spiral part 41 can effectively improve the problems of line clamping, line hanging, line cutting or line stretching when the heating host 100 rotates to unfold or fold, and ensure normal use of the clothes dryer.

[0062] It should be noted that the spiral part 41 can be elastically stretched and contracted between the first connecting part 42 and the second connecting part 43, referring to Figure 9 When the second shell main body 20 rotates to fold relative to the first shell main body 10, the second connecting part 43 rotates together with the second shell main body 20, and the first connecting part 42 remains stationary relative to the first shell main body 10. At this time, the second connecting part 43 moves relative to the first connecting part 42. With the complete folding of the first shell main body 10 and the second shell main body 20, the distance between the first connecting part 42 and the second connecting part 43 increases, so that the spiral part 41 is stretched. Since the spiral part 41 has the stretching and contracting performance, the risk of being broken can be effectively avoided. Referring to Figure 7 When the first shell main body 10 rotates to unfold relative to the second shell main body 20, the second connecting part 43 also moves relative to the first connecting part 42. With the complete unfolding of the first shell main body 10 and the second shell main body 20, the distance between the first connecting part 42 and the second connecting part 43 decreases, so that the spiral part 41 is elastically retracted. This avoids the spiral part 41 being in a relaxed state due to contraction, and effectively improves the problems of line clamping, line hanging, line cutting and the like with the surrounding structure when unfolding.

[0063] In some embodiments, referring to Figure 11The heat supply host 100 further comprises a temperature limiter 71 and a controller 80, the temperature limiter 71 is arranged in the first shell body 10 and the second shell body 20, the temperature limiter 71 is electrically connected with the corresponding heating body 70, and the controller 80 is arranged in the first shell body 10 and electrically connected with the heating body 70 in the first shell body 10. In this way, the temperature limiter 71 and the controller 80 are introduced to ensure the stable operation of the heat supply host 100.

[0064] It should be noted that there are various circuit connections between the heating body 70, the temperature limiter 71 and the controller 80, for example, please refer to Figure 10 The three wires 44 are led out at either end of the spiral part 41, wherein the first gear of the two heating bodies 70 is electrically connected through the wire 44, the second gear of the two heating bodies 70 is electrically connected through the wire 44, and the temperature limiter 71 in the second shell body 20 is connected with the controller 80 through the wire 44. At the same time, the first gear and the second gear of the heating body 70 in the first shell body 10 are also connected with the controller 80, respectively. Of course, the circuit connection between the heating body 70, the temperature limiter 71 and the controller 80 can also be other, since the circuit connection is not the object to be improved in the embodiment, and therefore, it is not described in detail here.

[0065] In some embodiments, the application provides a clothes dryer, which comprises the heat supply host 100 of any one of the above.

[0066] The clothes dryer described above adopts the heat supply host 100 described above, and the electric connecting piece 40 is arranged in the second shaft shell 21, one end of the electric connecting piece 40 extends into the first shaft shell 11 and is fixed, and the other end is fixed in the second shaft shell 21 or the second shell body 20. In this way, when the first shaft shell 11 rotates relative to the second shaft shell 21, the two ends of the electric connecting piece 40 will move relatively, so that the electric connecting piece 40 is elongated or contracted. Since one end of the first shaft shell 11 is provided with the first guide part 12 extending along the outer periphery of the axis 111, when the one end of the electric connecting piece 40 rotates with the first shaft shell 11 or the second shaft shell 21, the electric connecting piece 40 will be limited by the first guide part 12, so that the elongation or contraction of the electric connecting piece 40 is carried out on a certain track, avoiding the problems of wire clamping, wire hanging or wire cutting between the electric connecting piece 40 and the surrounding structure when the electric connecting piece 40 is elongated or contracted, and ensuring the normal operation of the heat supply host 100.
