Description

Technical Field

[0001] This invention relates to heating components, and more specifically, to heating components with improved heat transfer performance. Background Technology

[0002] In the past, spinal thermotherapy massage devices have been widely used to relieve acute or chronic pain in the muscles and nerve tissues of the spine caused by prolonged work in an inappropriate posture or by such posture becoming a habit, to improve blood circulation, or to eliminate momentary muscle stiffness. These devices move along the body and apply heat stimulation to the painful area to improve blood flow.

[0003] This spinal warming massage device features a heated massage ball that applies heat while simultaneously applying pressure to the user. The massage ball has a PTC heater at its center that heats up when an electric current is applied.

[0004] However, the PTC heater is fixed in the center of the massage ball in a non-rotating state in order to connect to the power supply. If this structure is adopted, a small gap is formed between the PTC heater fixed in a non-rotating state and the massage ball that is rotatably arranged, which will reduce the effect of warm massage.

[0005] Alternatively, the PTC heater can be configured to contact the massage ball, allowing heat to be transferred between the PTC heater and the massage ball via conduction. However, if this configuration is used, noise may be generated due to friction during the rotation of the massage ball, and durability may be reduced as wear occurs between the two.

[0006] Therefore, it is necessary to develop technologies that can solve these problems. Summary of the Invention

[0007] The present invention aims to solve the above problems. The purpose of the present invention is to provide a heating component with improved heat transfer performance, which can fully transfer heat to the user and enable the heating component to rotate smoothly.

[0008] The subject matter of this invention is not limited to the subject matter mentioned above, and other subject matters not mentioned can be clearly understood by those skilled in the art from the following description.

[0009] According to one aspect of the present invention, a heating assembly with improved heat transfer performance is provided, which provides a warm massage effect while applying pressure to a user. The heating assembly includes: a heating element having a heater, an outer cover component rotatably disposed outside the heating element, and a bushing component rotatably supporting the outer cover component.

[0010] At this time, the bushing component may include a bushing rib having a bushing support surface that extends circumferentially to support the inner surface of the outer cover component.

[0011] At this point, a side plate may also be included, which is axially disposed on at least one side to prevent the interior of the heating assembly from being exposed, wherein the side plate has a support rib disposed close to the heating element, and the bushing rib may be coupled to the support rib.

[0012] At this time, at least two bushing components can be provided, and each bushing component can be arranged on a concentric circle.

[0013] At this time, at least two support ribs may be provided, and each support rib may be configured to support the bushing component circumferentially.

[0014] At this time, the bushing component and the support rib can be arranged on concentric circles, and the radius of the bushing component can be formed to be larger than the radius of the support rib.

[0015] At this time, the support rib may include: a first unit rib that supports the radially outer side of the heating element, and the bushing rib is coupled to the first unit rib; and a second unit rib that supports the radially inner side of the heating element.

[0016] At this time, multiple first unit ribs may be provided, and the bushing component may also include bushing extension ribs, which are disposed between the first unit ribs that are arranged adjacent to each other.

[0017] At this time, the bushing component may also include a fixing rib, which is supported on the radial inner surface of the first unit rib.

[0018] At this time, the support rib may also include a third unit rib that supports the heating component circumferentially.

[0019] At this time, the circumferential end of the bushing rib can be tightly supported against the circumferential end of the third unit rib.

[0020] At this time, the third unit rib may have a rib spacing surface, which is arranged on a concentric circle with the bushing support surface having a first radius, and has a second radius smaller than the first radius.

[0021] At this point, the bushing rib may have a radius-reduced surface so that the radius of the circumferential end of the bushing rib has the second radius.

[0022] At this time, the bushing component may also include a bushing coupling rib that extends radially outward to engage with the inner surface of the side plate.

[0023] According to the aforementioned configuration, the heating assembly with improved heat transfer performance according to one aspect of the invention has a heating element having a heater, an outer cover component rotatably disposed outside the heating element, and a bushing component rotatably supporting the outer cover component, thereby not only improving heat transfer performance but also enabling the outer cover component to rotate smoothly, thereby improving operational stability and user satisfaction.

[0024] The effects of the present invention are not limited to those described above, but should be understood to include all effects that can be derived from the inventive structure described in the detailed description of the present invention or the claims. Attached Figure Description

[0038] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement the invention. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. For the sake of clarity, parts unrelated to the description have been omitted from the drawings, and the same reference numerals are used throughout the specification for the same or similar constituent elements.

[0039] The words and terms used in this specification and claims should not be limited to their usual or dictionary meanings, but should be interpreted as meanings and concepts consistent with the technical ideas of this invention, based on the principle that inventors may define terms and concepts in order to best explain their invention.

[0040] Therefore, the embodiments described in this specification and the configurations shown in the accompanying drawings are preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, at the time of application of the present invention, there may be various equivalents and modifications that can replace the corresponding configurations.

[0041] In this specification, terms such as “comprising” or “having” are intended to describe the presence of features, figures, steps, actions, constituent elements, components or combinations thereof described in the specification, and should be understood as not precluding the possibility of the presence or addition of one or more other features, figures, steps, actions, constituent elements, components or combinations thereof.

[0042] Figure 1 A perspective view is provided to illustrate a heating assembly with improved heat transfer performance according to an embodiment of the present invention. Figure 2 This is an exploded perspective view illustrating a heating assembly with improved heat transfer performance according to an embodiment of the present invention. Here, direction a is axial, direction b is radial, and direction c is circumferential.

[0043] like Figure 1 as well as Figure 2As shown, the heating assembly 40 with improved heat transfer performance according to an embodiment of the present invention is a heating assembly 40 that provides a warm massage effect while applying pressure to the user. The heating assembly 40 includes: a heating element 100 having a heater 110, an outer cover member 200 rotatably disposed outside the heating element 100, and a bushing member 300 rotatably supporting the outer cover member 200.

[0044] That is, the outer cover component 200 is rotatably disposed outside the heating element 100 having the heater 110, and has a bushing component 300 that rotatably supports the outer cover component 200. This not only improves heat transfer performance but also allows the outer cover component 200 to rotate smoothly. Therefore, it does not generate noise during use and does not cause problems with reduced durability due to wear, thereby improving operational stability and user satisfaction. This outer cover component 200 can be made of an elastic material to reduce pain caused by pressure applied to the user during warm massage by the heating element 40. As an example, the outer cover component 200 can be made of silicone material. In this case, the heater 110 can be a PTC heater, but it is not necessarily limited to this. Any component capable of generating heat can also be a heating wire or other components.

[0045] This heating element 40 can be fixedly attached to the support arm 21 of the warm massage device. This support arm 21 is disposed on the support portion 20 of the warm massage device (described later) and can be configured to rotate at a certain angle during the warm massage process. The support arm 21 is fixedly attached to the inner cover member 120 (described later), into which the heater 110 is inserted, and an outer cover member 200 is rotatably disposed outside the inner cover member 120. Therefore, during the application of pressure to the user, the heating element 40 can not only stably support the user's body but also stably supply current to the heater 110.

[0046] At this time, the bushing member 300 can be combined with the side plate 400 described later, and can be configured such that the outer cover member 200 can rotate while in contact with the bushing member 300. With this configuration, even if the user's load is applied to the outer cover member 200, the outer cover member 200 can be rotated smoothly while stably supporting the user's load. At this time, the bushing member 300 can be configured to support the insert inner surface 211 of the insert 210 of the outer cover member 200.

[0047] This bushing component 300 can be made of synthetic resin material and can be manufactured by injection molding. Thus, when the bushing component 300 is made of synthetic resin material, it can provide the user with a sufficient feeling of warmth by blocking the heat transferred to the insert 210 via the heating element 100 from being released to the outside.

[0048] Figure 3 A perspective view of a bushing component of a heating assembly with improved heat transfer performance according to an embodiment of the present invention.

[0049] like Figure 3 As shown, the bushing component 300 may include a bushing rib 310 having a bushing support surface 311 extending circumferentially in the direction c to support the inner surface of the outer cover component 200. When the bushing component 300 is coupled to the side plate 400 described later, the bushing rib 310 extends axially inward in the direction a and supports the inner surface of the outer cover component 200. Therefore, even when a user's load is applied to the outer cover component 200, the load can be stably supported while allowing the outer cover component 200 to rotate smoothly. In this case, the bushing support surface 311 of the bushing rib 310 can be configured to support the insert inner surface 211 of the insert 210 of the outer cover component 200.

[0050] Figure 4 This is a perspective view showing the state in which the side plates of the heating assembly with improved heat transfer performance according to an embodiment of the present invention are separated. Figure 5 A side view showing the state in which the side plates of the heating assembly with improved heat transfer performance according to an embodiment of the present invention are separated.

[0051] like Figure 4 as well as Figure 5 As shown, it may also include a side plate 400, which is disposed along the axial direction a on at least one side to prevent the interior of the heating assembly 40 from being exposed. The side plate 400 has a support rib 410 that is closely disposed on the heating element 100, and a bushing rib 310 may be coupled to the support rib 410.

[0052] This side plate 400 can be integrated with the aforementioned support arm 21, thereby preventing the interior of the heating assembly 40 from being exposed and providing stable support for the user's load. Furthermore, with the support rib 410 closely fitted to the heating element 100 and the bushing rib 310 integrated with the support rib 410, the structural stability of the heating assembly 40 is improved.

[0053] Figure 6 for Figure 1 A sectional view of part I-I. Figure 7 A rear view showing the state of the side plate and bushing components of a heating assembly with improved heat transfer performance according to an embodiment of the present invention.

[0054] like Figure 6 as well as Figure 7As shown, at least two bushing components 300 can be provided, and each bushing component 300 can be arranged on a concentric circle. With this configuration, the bushing components 300 can stably support the insert 210 while allowing the insert 210 to rotate smoothly.

[0055] like Figure 6 as well as Figure 7 As shown, at least two support ribs 410 can be provided, and each support rib 410 can be configured to support the bushing member 300 in the circumferential direction c. When configured in this way, the insert 210 can be stably supported when the bushing member 300 is engaged with the support rib 410.

[0056] like Figure 6 As shown, the bushing component 300 and the support rib 410 can be arranged on concentric circles, and the radius of the bushing component 300 can be formed to be larger than the radius of the support rib 410. When configured in this way, with the bushing component 300 engaged with the support rib 410, the bushing component 300 supports the inner surface of the insert 210, and the support rib 410 can be spaced apart from the inner surface of the insert 210. Therefore, not only can the insert 210 rotate smoothly, but the durability of the support rib 410 can also be prevented from decreasing, and noise caused by friction between the support rib 410 and the insert 210 can also be prevented.

[0057] like Figure 6 as well as Figure 7 As shown, the support rib 410 may include: a first unit rib 411, which supports the outer radial side of the heating element 100, and a bushing rib 310 is attached to the first unit rib 411; and a second unit rib 412, which supports the inner radial side of the heating element 100.

[0058] That is, in order to effectively support the user load applied through the outer cover component 200, it is important to support the heating component 100 evenly. When the first unit rib 411 supports the radially b outer side of the heating component 100 and the second unit rib 412 supports the radially b inner side of the heating component 100, structural stability can be ensured even when the user load is applied.

[0059] Furthermore, if the bushing rib 310 is configured to be combined with the first unit rib 411 on the radially outer side of the supporting heating component 100, the bushing component 300 can be easily combined, thereby improving manufacturability, and the outer cover component 200 can be rotated smoothly while effectively supporting the user load applied by the outer cover component 200.

[0060] like Figure 7As shown, multiple first unit ribs 411 can be provided, and the bushing component 300 may further include bushing extension ribs 320, which are disposed between adjacent first unit ribs 411. In this case, multiple first unit ribs 411 can be provided along the circumferential direction c.

[0061] Thus, when multiple first unit ribs 411 are provided, the user's load can be effectively supported, and when the bushing extension ribs 320 of the bushing component 300 are arranged between the adjacent first unit ribs 411, the bushing component 300 can be easily joined, thereby improving manufacturability.

[0062] like Figure 7 As shown, the bushing component 300 may also include a fixing rib 330, which is supported on the radially b inner surface of the first unit rib 411.

[0063] That is, when the bushing component 300 is attached to the side plate 400, the bushing rib 310 is in close contact with the radial b outer surface of the first unit rib 411, the bushing extension rib 320 is disposed between the adjacent first unit ribs 411, and the fixing rib 330 is in close contact with the radial b inner surface of the first unit rib 411.

[0064] With this configuration, the bushing component 300 can be easily attached to the side plate 400, and even if a user load is applied, the bushing component 300 will not detach from the side plate 400 and can stably support the user load.

[0065] like Figure 7 As shown, the support rib 410 may also include a third unit rib 413 that supports the heating component 100 along the circumferential direction c.

[0066] As mentioned above, in order to effectively support the user load applied by the outer cover component 200, it is important to uniformly support the heating component 100. By configuring the third unit rib 413 to support the heating component 100 in the circumferential direction c, with the first unit rib 411 supporting the outer radial b of the heating component 100, the second unit rib 412 supporting the inner radial b of the heating component 100, the structural stability of the heating assembly 40 can be ensured even when the user load is applied.

[0067] Figure 8 To be Figure 6 The enlarged cross-sectional view shown in part A.

[0068] like Figure 8 As shown, the circumferential c-end of the bushing rib 310 can be closely supported against the circumferential c-end of the third unit rib 413.

[0069] That is, when the user's load is applied to the outer cover member 200, when the outer cover member 200 rotates, a rotational force is applied to the bushing member 300 due to the rotation of the outer cover member 200. Therefore, if the circumferential c-end of the bushing rib 310 is configured to be tightly supported against the circumferential c-end of the third unit rib 413, stable support can be achieved even if a rotational force is applied to the bushing member 300 due to the rotation of the outer cover member 200.

[0070] like Figure 7 As shown, the third unit rib 413 may have a rib spacing surface 413a, which is arranged on a concentric circle with the bushing support surface 311 having a first radius r1, and has a second radius r2 that is smaller than the first radius r1.

[0071] As previously described, by configuring the heating element 100 such that the first unit rib 411 supports the outer radial side (b), the second unit rib 412 supports the inner radial side (b), and the third unit rib 413 supports the heating element 100 circumferentially (c), the structural stability of the heating assembly 40 can be ensured even when a user load is applied. Since the bushing component 300 is made of a highly wear-resistant material, its durability is not reduced even when a rotational force is applied to the outer cover component 200, and it can stably support the load. However, since the side plate 400 with the third unit rib 413 is not made of a wear-resistant material, it is important that it is configured so that no rotational force from the outer cover component 200 is applied to it.

[0072] Therefore, with the bushing support surface 311 of the bushing rib 310 configured to have a first radius r1, by configuring the rib spacing surface 413a of the third unit rib 413 to have a second radius r2 smaller than the first radius r1, the third unit rib 413 can be spaced apart from the inner surface of the outer cover member 200, thus preventing a decrease in the durability of the side plate 400.

[0073] like Figure 8 As shown, the bushing rib 310 may have a radius-reducing surface 312 so that the radius of the circumferential c end of the bushing rib 310 has a second radius r2.

[0074] That is, since the bushing support surface 311 of the bushing rib 310 is configured to have a first radius r1, and the rib spacing surface 413a of the third unit rib 413 is configured to have a second radius r2 smaller than the first radius r1, a step may be formed between the bushing support surface 311 and the rib spacing surface 413a. However, if such a step is formed, there may be a risk of workers being injured by such a step during the manufacturing process.

[0075] Therefore, as mentioned above, when the bushing rib 310 has a radius-reducing surface 312 so that the radius of the circumferential c end of the bushing rib 310 has a second radius r2, the aforementioned step will not be formed, thereby preventing potential safety accidents during the manufacturing process.

[0076] like Figure 3 as well as Figure 7 As shown, the bushing component 300 may further include a bushing engagement rib 340 that extends radially outward (b) to engage with the inner surface of the side plate 400. By configuring this bushing engagement rib 340 to extend radially outward (b), the contact area is increased when engaging with the side plate 400, thereby improving the engagement force.

[0077] The inner surface of the bushing connecting rib 340 in the axial direction a can be bent and configured with the bushing support surface 311. If the bushing support surface 311 and the inner surface of the bushing connecting rib 340 in the axial direction a support the insert 210, the insert 210 and the outer cover component 200 can rotate stably.

[0078] Figure 9 for Figure 1 A sectional view of part II-II.

[0079] like Figure 9 As shown, the outer cover component 200 may have an insert 210 arranged circumferentially c to transfer heat generated by the heater 110.

[0080] That is, the outer cover component 200 is rotatably disposed outside the heating component 100 having the heater 110, and the outer cover component 200 has an insert 210 disposed in the circumferential direction c to transfer the heat generated by the heater 110, thereby not only improving the heat transfer performance, but also enabling the outer cover component 200 to rotate smoothly. Therefore, no noise is generated during use, and there is no problem of reduced durability due to wear, thereby improving the working stability and user satisfaction.

[0081] like Figure 9 As shown, the outer cover component 200 can be integrally formed with the insert 210 by injection molding while the insert 210 is inserted.

[0082] This insert 210 can be made of aluminum, a material with high thermal conductivity, to ensure that the heat generated by the heater 110 is smoothly transferred to the outer cover component 200. However, it is not necessarily limited to this material; any material with high thermal conductivity can be used. This insert 210 can be integrally formed with the outer cover component 200 during the injection molding process.

[0083] Furthermore, the insert 210 can be formed to extend along the axial direction a to ensure structural stability while supporting the inner surface of the outer cover component 200. Thus, during the manufacturing process of the heating assembly 40, not only can the outer cover component 200 be easily assembled, but the load can also be stably supported even when the user's load is applied to the heating assembly 40 during the warm massage process.

[0084] Furthermore, the inner surface of the insert 210 may have a sliding surface, which allows the outer cover component 200 to rotate smoothly.

[0085] Figure 10 To be Figure 2 The three-dimensional view shown after the insert is separated is as follows. Figure 11 for Figure 10 A sectional view of part IV-IV.

[0086] like Figure 10 as well as Figure 11 As shown, the insert 210 may include: an inner surface 211 of the insert, which extends circumferentially c about the rotation axis ax, so that heat generated by the heater 110 is transferred; and an outer surface 212 of the insert, which extends circumferentially c about the rotation axis ax, so that heat transferred through the inner surface 211 of the insert is transferred to the outer cover member 200.

[0087] The inner surface of this insert 210 is arranged to extend circumferentially c around the rotation axis ax, thereby uniformly transferring the heat generated by the heater 110. That is, by configuring the inner surface 211 of the insert to be in direct contact with the heating element 100, heat can be transferred by conduction. Alternatively, for the portion where a gap is formed between the outer surface of the heating element 100 and the inner surface 211 of the insert due to manufacturing errors, heat can also be transferred by convection or radiation.

[0088] Furthermore, the outer surface 212 of the insert extends circumferentially c around the rotation axis ax and is configured to contact the inner surface of the outer cover component 200, thereby allowing the heat transferred to the insert 210 to be smoothly transferred to the outer surface of the outer cover component 200 and providing a warm feeling to the user.

[0089] At this time, the inner surface 211 of the insert can be extended to keep the radial distance d1 from the rotation axis ax constant. As mentioned above, the inner surface of this insert 210 is arranged to extend circumferentially c with the rotation axis ax as the center, and since the radial distance d1 from the rotation axis ax remains constant, the heat generated by the heater 110 can be uniformly transferred. Furthermore, as the contact state between the inner surface 211 of the insert and the heating element 100 remains constant, stable heat transfer can be achieved.

[0090] like Figure 11As shown, the outer surface 212 of the insert may include: a first unit surface 212a, which has an increased radial distance d2 from the rotation axis ax; and a second unit surface 212b, which has a decreased radial distance d2 from the rotation axis ax.

[0091] That is, the first unit surface 212a and the second unit surface 212b are arranged sequentially along the axial direction a. The first unit surface 212a is configured such that the radial distance d2 between it and the rotation axis ax along the axial direction a increases, and the radial distance d2 between it and the rotation axis ax along the axial direction a decreases.

[0092] With this configuration, during the warm massage process, even if the heating component 40 moves in various directions with the movement of the support arm 21, it can still stably adhere to the user's body, thereby providing sufficient warmth while applying sufficient pressure to the user's body.

[0093] At this time, the first unit surface 212a and the second unit surface 212b can be arranged on concentric circles. When configured in this way, the user can feel comfortable when pressure is applied to the user's body.

[0094] like Figure 11 As shown, the outer surface 212 of the insert may have a first recessed surface 212c, which is arranged to extend along the axial direction a so that the radial interval distance d3 from the rotation axis ax remains constant.

[0095] As mentioned above, during the warm massage process, the heating component 40 moves in various directions with the movement of the support arm 21. When it has a first recessed surface 212c that extends along the axial direction a so that the radial interval distance d3 from the rotation axis ax is kept constant, during the injection molding process of the outer cover component 200, a portion of the inner surface of the outer cover component 200 can be inserted into the first recessed surface 212c. Thus, the outer cover component 200 and the insert 210 will not slip, thereby preventing the outer cover component 200 from spinning freely.

[0096] like Figure 11 As shown, at least one of the two ends of the insert 210 in the axial direction a may have an insert extension rib 213 extending in the circumferential direction c.

[0097] Thus, when the insert extension rib 213 is provided, the contact area between the inner surface of the outer cover component 200 and the outer surface 212 of the insert is increased, thereby enabling stable support.

[0098] Figure 12 for Figure 1 Sectional view of part III-III.

[0099] like Figure 12As shown, the outer surface 212 of the insert and the outer surface of the outer cover component 200 can be extended to keep the radial b-distance constant.

[0100] As described above, a first unit surface 212a and a second unit surface 212b are sequentially arranged along the axial direction a on the outer surface 212 of the insert. The first unit surface 212a is configured such that the radial interval d2 between the first unit surface and the rotation axis ax increases along the axial direction a, while the radial interval d2 between the second unit surface and the rotation axis ax decreases along the axial direction a. Therefore, the outer surface of the outer cover component 200 also has a range where the radial interval d2 between the first unit surface and the second unit surface decreases along the axial direction a. Thus, the radial interval d2 between the second unit surface and the outer surface 212 of the insert remains constant. As a result, even if the heating component 40 moves in various directions with the movement of the support arm 21 during the warm massage, it can stably fit against the user's body, thereby providing sufficient warmth while applying sufficient pressure to the user's body.

[0101] like Figure 9 As shown, the heating assembly 40 may also include a rotating component 500 disposed between the heating component 100 and the outer cover component 200.

[0102] That is, since there is a rotating member 500 between the heating element 100 and the outer cover member 200, as heat is transferred through the rotating member 500 by conduction, not only is the warm massage effect improved, but the outer cover member 200 can also rotate smoothly through the rotating member 500. Therefore, no noise is generated during use, and there is no problem of reduced durability due to wear. At this time, the rotating member 500 can be configured as the inner surface 211 of the insert 210 of the outer cover member 200.

[0103] like Figure 9 As shown, the heating element 100 may further include an inner cover element 120 into which the heater 110 is inserted, and the rotating element 500 may be a rotating pin 510 inserted into an insertion groove 120a on the outer surface of the inner cover element 120. The rotating pin 510 may support the inner surface of the outer cover element 200 when inserted into the insertion groove 120a. In this case, the rotating pin 510 may be configured to support the inner surface 211 of the insert 210 of the outer cover element 200.

[0104] The radially b outer side of the insertion groove 120a may have an opening to expose a portion of the rotating pin 510 radially b. That is, the rotating pin 510 can be exposed radially b outward from the insertion groove 120a through the opening. This exposed portion, while in contact with the outer cover component 200, conducts heat, thereby improving the warm massage effect. Furthermore, the outer cover component 200 can rotate smoothly via the rotating pin 510, thus preventing noise during use and avoiding wear-related durability reduction.

[0105] like Figure 9 As shown, the inner cover component 120 may include: a first inner cover 121 disposed on one radial side b to surround the heater 110; and a second inner cover 122 disposed on the other radial side b to surround the heater 110.

[0106] That is, with a first inner cover 121 arranged on one radial side b to surround the heater 110, and a second inner cover 122 arranged on the other radial side b, the two are fixed together. At this time, either the first inner cover 121 or the second inner cover 122 may have a mating protrusion, and the other inner cover may have a mating groove. The first inner cover 121 and the second inner cover 122 are fixed together by the mating protrusion being inserted into the mating groove in an interference fit. However, the method of fixing the first inner cover 121 and the second inner cover 122 is not limited to the above configuration. Other methods can be used to fix them together as long as they can be stably fixed together.

[0107] like Figure 9 As shown, at least one of the first inner cover 121 and the second inner cover 122 may have an insertion slot 120a.

[0108] That is, as described above, when the first inner cover 121 and the second inner cover 122 are fixed to each other, since at least one of the inner covers 121 and the second inner cover 122 has an insertion groove 120a, the outer cover component 200 can be rotatably configured when the rotating pin 510 is inserted into such an insertion groove 120a. Thus, even if the first inner cover 121 and the second inner cover 122 undergo thermal expansion during the heat transfer process generated by the heater 110 through the first inner cover 121 and the second inner cover 122, the heat transfer performance can be prevented from decreasing. This allows for sufficient heat transfer to the user and a stable connection between the first inner cover 121 and the second inner cover 122.

[0109] Figure 13 This diagram illustrates the configuration of a warm massage device including a heating component with improved heat transfer performance according to an embodiment of the present invention.

[0110] like Figure 13 As shown, a warm massage device including a heating component 40 with improved heat transfer performance according to an embodiment of the present invention may include: a transfer part 10 for moving the heating component 40, which applies pressure to the user, along the length direction; a support part 20 having a support arm 21 to which the heating component 40 is fixedly attached; and a lifting part 30 for raising or lowering the support part 20 along the height direction.

[0111] This heated massage device can be inserted into a pad that supports the user's body, and while inserted into the pad, the heated massage device moves along its length (in the same direction as the user's spine) and applies pressure to the user's body.

[0112] This type of cushion can be installed in the main body that supports the user's upper body, and the main body can be connected to an auxiliary part that supports the user's lower body. In this case, the main body can also be configured to support not only the user's upper body but also the buttocks, while the auxiliary part can be configured to support only the user's legs.

[0113] At this time, the pad can also be set in the auxiliary part that supports the user's lower body, and it can also be configured such that both the main body and the auxiliary part have pads.

[0114] The main body of the pad can have separate support leg components so that the upper surface of the pad is spaced apart from the ground, thereby allowing the user to receive a massage in a comfortable posture.

[0115] This support leg component can be manufactured in a generally four-cornered strip shape. That is, it can include a side frame corresponding to the side of the main body, a lower frame supporting the ground, and a connecting frame connecting the side frame and the lower frame. The above frames can be manufactured as a single piece or manufactured separately and then combined. Here, the side frame can be made into a plate shape, and the lower frame can be made into a rod shape.

[0116] The main body may have a guide groove, and the auxiliary part may have a guide protrusion that inserts into the guide groove, thereby allowing the auxiliary part to slide. Alternatively, a guide groove may be formed in the auxiliary part, and a guide protrusion may be formed in the main body, thereby allowing the auxiliary part to slide.

[0117] Heating components 40 can be respectively configured on both sides in the width direction (the direction on both sides centered on the user's spine), thereby providing a massage effect while applying pressure to acupoints located on both sides of the user's spine (for example, acupoints on the Bladder Meridian of Foot Taiyang).

[0118] At this time, the transfer unit 10 may have a plate-shaped transfer plate component that houses the support unit 20 and the lifting unit 30, and the transfer plate component may have base ribs at both ends in the width direction. The base ribs may have support rollers, which may be configured to move along a guide rail arranged in the length direction. In addition, the transfer unit 10 may also have a transfer drive component that provides driving force to move the support rollers along the guide rail.

[0119] Furthermore, the support part 20 may be equipped with the aforementioned support arm 21, enabling the support arm 21 to rotate at a certain angle. The lifting part 30 may have a rack and pinion-shaped lifting component and a pinion-shaped lifting drive component. The lifting drive component may be connected to a separate drive motor and may be configured such that the lifting component rises or falls according to rotation in one direction or another.

[0120] As previously described, the heat transfer performance improved heating assembly 40 according to an embodiment of the present invention has a heating element 100 having a heater 110, an outer cover member 200 rotatably disposed outside the heating element 100, and a bushing member 300 rotatably supporting the outer cover member 200, thereby not only improving heat transfer performance, but also enabling the outer cover member 200 to rotate smoothly, thereby improving operational stability and user satisfaction.

[0121] Although one embodiment of the present invention has been described, the spirit of the present invention is not limited to the embodiment shown in this specification. Those skilled in the art who understand the spirit of the present invention can easily propose other embodiments by adding, changing, deleting, or supplementing the constituent elements within the same spirit, and these should also fall within the spirit of the present invention.
