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 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; and an outer cover member rotatably disposed outside the heating element and having an insert arranged circumferentially to transfer the heat generated by the heater.

[0010] At this time, the insert may include an inner surface and an outer surface. The inner surface of the insert may be arranged to extend circumferentially around the rotation axis so that the heat generated by the heater is transferred. The outer surface of the insert may be arranged to extend circumferentially around the rotation axis so that the heat transferred through the inner surface of the insert is transferred to the outer cover component.

[0011] At this time, the outer surface of the insert may have a first fixing surface, which is arranged to extend circumferentially so that the radial distance from the rotation axis remains constant.

[0012] At this time, the outer surface of the insert may have a second fixing surface, which is arranged to extend axially so that the radial distance from the rotation axis remains constant.

[0013] At this time, at least one of the two axial ends of the insert may have an extension rib extending circumferentially.

[0014] At this time, the extension rib may have a third fixing surface that extends circumferentially.

[0015] At this time, the outer surface of the insert may include at least one unit surface, and the radial distance between the unit surface and the rotation axis may be increased or decreased.

[0016] At this time, multiple unit surfaces may be included, and the unit surfaces arranged adjacent to each other may have a first fixed surface, which is arranged to extend circumferentially so that the radial spacing distance from the rotation axis remains constant.

[0017] At this time, the outer surface of the insert may have a reference point with the radial distance from the rotation axis forming the maximum, and the first fixing surface may be configured at a position where the radial distance from the rotation axis is less than the radial distance at the reference point.

[0018] At this time, the outer surface of the insert may have a reference point with the radial distance from the rotation axis forming the maximum, and the first fixing surface may be configured at a position where the radial distance from the rotation axis is greater than the radial distance at the reference point.

[0019] At this time, the outer surface of the insert may also have a second fixing surface, which is arranged to extend axially so that the radial distance from the rotation axis remains constant. The second fixing surface may be configured such that the radial distance from the rotation axis is the same as or different from the radial distance from the first fixing surface to the rotation axis.

[0020] At this time, the outer surface of the insert may have a reference point with the radial distance from the rotation axis forming the maximum, and the second fixing surface may be configured at a position where the radial distance from the rotation axis is less than the radial distance at the reference point.

[0021] At this time, the outer surface of the insert may have a reference point with the radial distance from the rotation axis forming the maximum, and the second fixing surface may be configured at a position where the radial distance from the rotation axis is greater than the radial distance at the reference point.

[0022] At this time, the outer surface of the insert and the outer surface of the outer cover component can be extended to keep the radial spacing distance constant.

[0023] According to the aforementioned configuration, one aspect of the present invention, a heating assembly with improved heat transfer performance, includes a heating element having a heater and an outer cover component rotatably disposed on the outer surface of such heating element. The outer cover component has an insert arranged circumferentially to transfer heat generated by the heater, 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

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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 An exploded perspective view of a heating assembly with improved heat transfer performance according to an embodiment of the present invention is shown. Figure 3 To show Figure 1 A sectional view of part I-I. Figure 4 To show Figure 1 Sectional view of part II-II, Figure 5 To show Figure 1 A sectional view of section III-III. Here, direction a is axial, direction b is radial, and direction c is circumferential.

[0044] like Figure 1 as well as Figure 2 As shown, according to an embodiment of the present invention, the heating component 40 with improved heat transfer performance provides a warm massage effect while applying pressure to the user, such as... Figures 3 to 5 As shown, this heating assembly 40 includes: a heating element 100 having a heater 110; and an outer cover member 200 rotatably disposed outside the heating element 100 and having an insert 210 disposed circumferentially c to transfer the heat generated by the heater 110.

[0045] That is, the outer cover component 200 is rotatably disposed outside the heating component 100 having the heater 110, and this outer cover component 200 has an insert 210 arranged circumferentially c to transfer the heat generated by the heater 110, thereby not only improving heat transfer performance, but also allowing 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 operational stability and user satisfaction. This outer cover component 200 can be made of an elastic material to reduce pain caused by pressure during the application of pressure by the heating component 40 to the user during warm massage. 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.

[0046] 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.

[0047] like Figures 3 to 5 As shown, the outer cover component 200 can be integrally formed with the insert 210 in the inserted state through an injection molding process. This insert 210 can be made of aluminum, a material with high thermal conductivity, to ensure smooth heat transfer from the heater 110 to the outer cover component 200; however, it is not limited to this material, and 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.

[0048] 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, the outer cover component 200 can be easily assembled during the manufacturing process of the heating assembly 40, and the load can be stably supported even when the user's load is applied to the heating assembly 40 during the warm massage process.

[0049] In addition, the inner surface of the insert 210 may have a sliding surface, which allows the outer cover component 200 to rotate smoothly.

[0050] Figure 6 A perspective view showing an insert of a heating assembly with improved heat transfer performance according to an embodiment of the present invention.

[0051] like Figure 6 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.

[0052] 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, the inner surface 211 of the insert can transfer heat by conduction by being configured to directly contact the heating element 100. 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.

[0053] 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, so that the heat transferred to the insert 210 is smoothly transferred to the outer surface of the outer cover component 200, thereby providing the user with a warm feeling.

[0054] Figure 7 To be Figure 3 The cutaway view shown after the insert has been separated.

[0055] like Figure 7 As shown, the inner surface 211 of the insert can be extended to keep the radial b-distance d1 from the rotation axis ax constant.

[0056] As previously described, the inner surface of this insert 210 is arranged to extend circumferentially c around the rotation axis ax, and the heat generated by the heater 110 can be uniformly transferred as the radial distance b from the rotation axis ax remains constant. Furthermore, heat transfer can be stably achieved as the contact state between the inner surface 211 of the insert and the heating element 100 remains constant.

[0057] Figure 8 To be Figure 7 The enlarged cross-sectional view shown in part A.

[0058] like Figure 8 As shown, the outer surface 212 of the insert may have a first fixing surface 212c, which extends circumferentially c to keep the radial distance d3 from the rotation axis ax constant. Thus, when the first fixing surface 212c is present, during the injection molding of the outer cover component 200, a portion of the inner surface of the outer cover component 200 can be inserted into the first fixing surface 212c, thereby preventing the outer cover component 200 from sliding and detaching. The first fixing surface 212c may be formed as a shape recessed radially b inward based on the outer surface 212 of the insert, or it may be formed as a shape protruding radially b outward based on the outer surface 212 of the insert. Furthermore, the first fixing surface 212c may also be formed as a shape that alternates between a shape recessed radially b inward based on the outer surface 212 of the insert and a shape protruding radially b outward.

[0059] like Figure 6 as well as Figure 7 As shown, the outer surface 212 of the insert may have a second fixing surface, which extends axially to keep the radial distance d4 from the rotation axis ax constant. As previously described, during the warm massage process, the heating component 40 moves in various directions with the movement of the support arm 21. When the second fixing surface 212d is provided to extend axially a to keep the radial distance d4 from the rotation axis ax constant, a portion of the inner surface of the outer cover component 200 can be inserted into the second fixing surface 212d during the injection molding of the outer cover component 200. This prevents slippage between the outer cover component 200 and the insert 210, thus preventing the outer cover component 200 from spinning freely. The second fixing surface 212d can be formed as a shape recessed radially inward from the outer surface 212 of the insert, or it can be formed as a shape protruding radially outward from the outer surface 212 of the insert. Furthermore, the second fixing surface 212d can also be formed as a shape that alternates between a shape that is recessed radially inward and a shape that protrudes radially outward, with the outer surface 212 of the insert as a reference.

[0060] like Figure 7 as well as Figure 8 As shown, at least one of the two ends of the insert 210 in the axial direction a may have an extension rib 213 extending in the circumferential direction c.

[0061] Thus, when the extended rib 213 is present, 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.

[0062] At this time, as Figure 8 As shown, the extending rib 213 may have a third fixing surface 213a extending in the circumferential direction c. Thus, when the third fixing surface 213a is present, the outer cover component 200 can be more effectively prevented from falling off in the axial direction a. In this case, the third fixing surface 213a may be formed in a shape that is recessed radially inward (b) based on the outer surface 212 of the insert, or it may be formed in a shape that protrudes radially outward (b) based on the outer surface 212 of the insert. Furthermore, the third fixing surface 213a may also be formed in a shape that alternates between a shape recessed radially inward (b) based on the outer surface 212 of the insert and a shape protruding radially outward (b).

[0063] like Figure 8As shown, the outer surface 212 of the insert may include at least one unit surface 212a, 212b, and the radial distance d2 between the unit surfaces 212a, 212b and the rotation axis ax may increase or decrease. Thus, when the unit surfaces 212a, 212b are present, even if the heating component 40 moves in various directions with the movement of the support arm 21 during the warm massage, it can still maintain stable and close contact with the user's body, thereby providing sufficient warmth while applying sufficient pressure to the user's body.

[0064] As one example, these unit surfaces 212a and 212b can be a first unit surface 212a with an increased radial spacing distance d2 from the rotation axis ax. As another example, these unit surfaces 212a and 212b can be a second unit surface 212b with a decreased radial spacing distance d2 from the rotation axis ax.

[0065] 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.

[0066] At this time, the first unit surface 212a and the second unit surface 212b can be arranged on concentric circles. If configured in this way, the user can feel comfortable when pressure is applied to the user's body.

[0067] like Figure 8 As shown, the device may include multiple unit surfaces 212a and 212b, and adjacent unit surfaces 212a and 212b may have a first fixing surface 212c. The first fixing surface 212c extends circumferentially c so that the radial distance d3 from the rotation axis ax remains constant. Thus, when the first fixing surface 212c is present, during the injection molding of the outer cover component 200, a portion of the inner surface of the outer cover component 200 can be inserted into the first fixing surface 212c, thereby preventing the outer cover component 200 from sliding and thus preventing it from falling off arbitrarily.

[0068] As an example, this first fixed surface 212c can be disposed between the first unit surface 212a and the second unit surface 212b.

[0069] As mentioned above, the first unit surface 212a is configured such that the radial distance d2 between the first unit surface and the rotation axis a is increased along the axial direction a, and the radial distance d2 between the second unit surface 212b and the rotation axis a is decreased along the axial direction a. Therefore, during the warm massage process, due to the movement of the heating component 40, the outer cover component 200 and the first unit surface 212a or the outer cover component 200 and the second unit surface 212b may slide along the axial direction a.

[0070] However, as mentioned above, when there is a first fixing surface 212c between the first unit surface 212a and the second unit surface 212b, during the injection molding of the outer cover component 200, a portion of the inner surface of the outer cover component 200 can be inserted and disposed on the first fixing surface 212c. Thus, the outer cover component 200 will not slide, thereby preventing the outer cover component 200 from falling off and arbitrarily detaching.

[0071] like Figure 8 As shown, the outer surface 212 of the insert can have reference points 212a1 and 212b1 with a radial interval distance b from the rotation axis ax, which is the largest. The first fixing surface 212c can be positioned where the radial interval distance b is less than the radial interval distance at reference points 212a1 and 212b1. With this configuration, during the warm massage process, when the heating component 40 applies pressure to the user, pressure is applied to the user's body only through the unit surfaces 212a and 212b, while the first fixing surface 212c does not apply pressure to the user's body. Therefore, any discomfort that the user may feel can be effectively eliminated.

[0072] At this time, the first unit surface 212a and the second unit surface 212b respectively have a first reference point 212a1 and a second reference point 212b1 with the largest radial interval distance b from the rotation axis ax. The first fixed surface 212c can be configured at a position where the radial interval distance b from the rotation axis ax is smaller than the radial interval distance at the first reference point 212a1 and the second reference point 212b1.

[0073] That is, during the warm massage process, when the heating component 40 applies pressure to the user, it applies pressure to the user's body only through the first unit surface 212a and the second unit surface 212b, while the first fixed surface 212c does not apply pressure to the user's body, thus effectively eliminating any discomfort that the user may feel.

[0074] At this time, the outer surface 212 of the insert can have reference points 212a1 and 212b1 with the radial interval distance b from the rotation axis ax being the largest, and the first fixing surface 212c can be arranged at a position where the radial interval distance b d3 is greater than the radial interval distance at reference points 212a1 and 212b1. With this configuration, the outer cover component 200 can be prevented from falling off and arbitrarily detaching.

[0075] Figure 9 To show Figure 6 A sectional view of part IV-IV.

[0076] like Figure 6 as well as Figure 9 As shown, the outer surface 212 of the insert may also have a second fixing surface 212d, which extends along the axial direction a to keep the radial b-distance d4 from the rotation axis a constant. The radial b-distance d4 of the second fixing surface 212d from the rotation axis a may be configured to be the same as or different from the first fixing surface 212c. That is, the radial b-distance d4 of the second fixing surface 212d may be configured to be the same as the radial b-distance d3 of the first fixing surface 212c, or the radial b-distance d4 of the second fixing surface 212d may be configured to be less than the radial b-distance d3 of the first fixing surface 212c, or the radial b-distance d4 of the second fixing surface 212d may be configured to be greater than the radial b-distance d3 of the first fixing surface 212c.

[0077] 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 the second fixing surface 212d is arranged to extend along the axial direction a so that the radial interval distance d4 from the rotation axis ax is kept constant, during the injection molding of the outer cover component 200, a portion of the inner surface of the outer cover component 200 can be inserted into the second fixing surface 212d. Thus, the outer cover component 200 and the insert 210 will not slip, thereby preventing the outer cover component 200 from spinning freely.

[0078] like Figure 9 As shown, the second fixing surface 212d can be configured at a position where the radial distance b from the rotation axis ax is less than the radial distance at the first fixing surface 212c. As previously described, the first fixing surface 212c is used to prevent sliding along the axial direction a between the outer cover component 200 and the first unit surface 212a or between the outer cover component 200 and the second unit surface 212b due to the movement of the heating component 40 during the warm massage process, thereby preventing the outer cover component 200 from falling off; the second fixing surface 212d is used to prevent sliding between the outer cover component 200 and the insert 210, thereby preventing the outer cover component 200 from spinning freely.

[0079] It is preferable to form the first fixing surface 212c and the second fixing surface 212d with sufficient size. However, if the size of the first fixing surface 212c and the second fixing surface 212d is excessively increased, the structural rigidity of the insert 210 may be reduced. Therefore, it is important to form the first fixing surface 212c and the second fixing surface 212d with appropriate size.

[0080] At this time, basically, during the warm massage process, the outer cover part 200 of the heating component 40 rotates together with the insert 210 around the rotation axis ax, and the movement of the heating component 40 along the axis a occurs only when required according to the warm massage mode.

[0081] That is, during the warm massage process, the rotation of the outer cover component 200 and the insert 210 always occurs, while the movement of the heating component 40 along the axial direction a only occurs when required according to the warm massage mode. Therefore, preventing the outer cover component 200 from spinning freely due to sliding between the outer cover component 200 and the insert 210 is more important than preventing the outer cover component 200 from falling off due to sliding between the outer cover component 200 and the first unit surface 212a or between the outer cover component 200 and the second unit surface 212b along the axial direction a.

[0082] Therefore, as the second fixing surface 212d is positioned at a radial distance b from the rotation axis ax that is less than the radial distance at the first fixing surface 212c, during the injection molding of the outer cover component 200, the degree to which a portion of the inner surface of the outer cover component 200 is inserted into the second fixing surface 212d is further increased compared to the degree to which it is inserted into the first fixing surface 212c. With this configuration, while ensuring the structural rigidity of the insert 210, it is possible to effectively prevent the outer cover component 200 from falling off along the axial direction a or from spinning freely.

[0083] Alternatively, even if the radial b-spacing distance d4 of the second fixing surface 212d is configured to be the same as the radial b-spacing distance d3 of the first fixing surface 212c, or if the radial b-spacing distance d4 of the second fixing surface 212d is configured to be greater than the radial b-spacing distance d3 of the first fixing surface 212c, it is still possible to effectively prevent the outer cover component 200 from falling off along the axial direction a or the outer cover component 200 from spinning freely while ensuring the structural rigidity of the insert 210.

[0084] like Figure 8 As shown, the outer surface 212 of the insert can have reference points 212a1 and 212b1 with a radial distance b from the rotation axis ax that is the largest, and the second fixing surface 212d can be positioned at a radial distance b d4 from the rotation axis ax that is smaller than the radial distance at reference points 212a1 and 212b1. With this configuration, during the warm massage process, when the heating component 40 applies pressure to the user, pressure is applied to the user's body only through the unit surfaces 212a and 212b, while the second fixing surface 212d does not apply pressure to the user's body, thus effectively eliminating any discomfort that the user may feel.

[0085] Alternatively, the outer surface 212 of the insert may have reference points 212a1 and 212b1 with a radial distance b from the rotation axis ax that is maximized, and the second fixing surface 212d may be positioned at a radial distance b d4 from the rotation axis ax that is greater than the radial distance between the reference points 212a1 and 212b1. With this configuration, the structural rigidity of the insert 210 can be ensured, and the outer cover component 200 can be effectively prevented from falling off along the axial direction a or from spinning freely.

[0086] like Figure 3 As 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. As previously described, 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 b-distance d2 from the rotation axis a increases along the axial direction a, and the second unit surface 212b is configured such that the radial b-distance d2 from the rotation axis a decreases along the axial direction a. Therefore, the outer surface of the outer cover component 200 also has sections along the axial direction a where the radial b-distance increases and sections where the radial b-distance decreases. Thus, by keeping the radial b-distance between it and the outer surface 212 of the insert constant, even when the heating component 40 moves in all directions with the movement of the support arm 21 during the warm massage, it can maintain stable and close contact with the user's body. This allows for sufficient pressure on the user's body while heat is evenly transferred along the circumferential direction c, thereby providing a sufficient warming sensation.

[0087] like Figures 2 to 4 As shown, the heating assembly 40 may further include a first side plate 300 disposed on one side of the axial direction a. The first side plate 300 may have a first support rib 310, which is inserted into the inner surface of the outer cover component 200 and disposed in contact with the heating component 100.

[0088] This first side plate 300 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 first support rib 310 in contact with the heating element 100, the structural stability of the heating assembly 40 is improved.

[0089] Or, such as Figures 2 to 4 As shown, the heating assembly 40 may also include a second side plate 400 disposed on the other side of axial direction a. The second side plate 400 may have a second support rib 410, which is inserted into the inner surface of the outer cover component 200 and disposed in contact with the heating component 100.

[0090] That is, in the design of the warm massage device, the second side plate 400 can be combined with the support arm 21, thereby not only preventing the interior of the heating component 40 from being exposed, but also stably supporting the user's load. In addition, with the second support rib 410 in contact with the heating element 100, the structural stability of the heating component 40 is improved.

[0091] Figure 10 A perspective view is provided to illustrate the first side plate of a heating assembly with improved heat transfer performance according to an embodiment of the present invention. Figure 11 A rear view of the first side plate of a heating assembly with improved heat transfer performance according to an embodiment of the present invention is shown.

[0092] like Figure 10 as well as Figure 11 As shown, the first side plate 300 or the second side plate 400 may have a first receiving groove AH1 and a second receiving groove AH2. An air layer may be formed inside the first receiving groove AH1 and the second receiving groove AH2, which can effectively prevent the heat generated by the heating element 100 from being released to the outside. The first side plate 300 and the second side plate 400 may be formed symmetrically to each other along the axial direction a.

[0093] like Figure 2 as well as Figure 5 As shown, the heating assembly 40 may further include a rotating member 500 disposed between the heating element 100 and the outer cover member 200. That is, because 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. In this case, the rotating member 500 can be configured as the inner surface 211 of the insert 210 of the outer cover member 200.

[0094] like Figure 2 as well as Figure 5 As shown, the heating element 100 may further include an inner cover element 120 into which the heater 110 is inserted, and a rotating element 500 is a rotating pin 510 inserted into an insertion groove 120a on the outer surface of the inner cover element 120. The rotating pin 510 can 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.

[0095] 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. As the portion exposed radially b outward contacts the outer cover component 200, heat is transferred by conduction, which not only improves the warm massage effect, but also allows the outer cover component 200 to rotate smoothly through the rotating pin 510. Therefore, no noise is generated during use, and there is no problem of reduced durability due to wear.

[0096] like Figure 5 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.

[0097] That is, with the first inner cover 121 positioned on one radial side (b) to surround the heater 110, and the second inner cover 122 positioned 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. As the mating protrusion is inserted into the mating groove with an interference fit, the first inner cover 121 and the second inner cover 122 are fixed together. 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.

[0098] like Figure 5 As shown, at least one of the first inner cover 121 and the second inner cover 122 may have an insertion slot 120a.

[0099] That is, as described above, with the first inner cover 121 and the second inner cover 122 fixed to each other, since at least one of the first inner cover 121 and the second inner cover 122 has an insertion groove 120a, the outer cover component 200 can be rotatably configured with the rotating pin 510 inserted into such an insertion groove 120a. Thus, during the heat generated by the heater 110 being transferred through the first inner cover 121 and the second inner cover 122, even if the first inner cover 121 and the second inner cover 122 undergo thermal expansion, sufficient heat can be transferred to the user by preventing a decrease in heat transfer performance, and the combined state of the first inner cover 121 and the second inner cover 122 can be stably maintained.

[0100] Figure 12 A perspective view is provided for a heating assembly with improved heat transfer performance according to an embodiment of the present invention, showing the bushing component. Figure 13A rear view showing the state in which the first side plate of the heating assembly with improved heat transfer performance according to an embodiment of the present invention is combined with the bushing component.

[0101] like Figure 12 as well as Figure 13 As shown, the heating assembly 40 may further include a bushing member 600 that rotatably supports the outer cover member. This bushing member 600 may be combined with the first side plate 300 and the second side plate 400, and may be configured such that the outer cover member 200 can rotate while in contact with the bushing member 600. With this configuration, even if a user's load is applied to the outer cover member 200, the outer cover member 200 can be stably supported while rotating smoothly. In this case, the bushing member 600 may be configured to support the inner surface 211 of the insert 210 of the outer cover member 200.

[0102] This bushing component 600 can be made of synthetic resin material and can be manufactured by injection molding. Thus, when the bushing component 600 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.

[0103] like Figure 12 as well as Figure 13 As shown, the bushing member 600 may have a bushing rib 610 that supports the inner surface of the outer cover member 200. With the bushing member 600 respectively attached to the first side plate 300 and the second side plate 400, the bushing rib 610 extends inward along the axial direction a and supports the inner surface of the outer cover member 200. Therefore, even when a user's load is applied to the outer cover member 200, the load can be stably supported while allowing the outer cover member 200 to rotate smoothly. In this case, the bushing rib 610 may be configured to support the inner surface 211 of the insert 210 of the outer cover member 200.

[0104] Figure 14 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.

[0105] like Figure 14 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.

[0106] This heated massage device can be inserted into a pad that supports the user's body, and while inserted into the pad, it applies pressure to the user's body as it moves along its length (in the same direction as the user's spine).

[0107] This type of cushion can be installed on the main body that supports the user's upper body, and the main body can be connected to an auxiliary body that supports the user's lower body. In this case, the main body can be configured to support not only the user's upper body but also the buttocks, and the auxiliary body can be configured to support only the user's legs.

[0108] 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.

[0109] 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.

[0110] This support leg component can be made into a generally rectangular 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 made as a single piece, or they can be made 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.

[0111] The main body can have a guide groove, and the auxiliary part can have a guide protrusion that inserts into the guide groove, thereby enabling the auxiliary part to slide. Alternatively, a guide groove can be formed in the auxiliary part, and a guide protrusion can be formed in the main body, thereby enabling the auxiliary part to slide.

[0112] 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 according to the Bladder Meridian of Foot Taiyang).

[0113] At this time, the transfer unit 10 may have a plate-shaped transfer plate component, with a support unit 20 and a lifting unit 30 disposed on the transfer plate component, and base ribs may be present at both ends in the width direction of the transfer plate component. The base ribs may have support rollers, which may be movably disposed along a guide rail disposed in the length direction. In addition, the transfer unit 10 may also have a transfer drive component, which provides driving force to move the support rollers along the guide rail.

[0114] Furthermore, the support portion 20 may be equipped with the aforementioned support arm 21, and the support arm 21 may be able to rotate at a certain angle. The lifting portion 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 to raise or lower the lifting component by rotating in one direction or another.

[0115] As previously described, a heating assembly 40 with improved heat transfer performance according to an embodiment of the present invention includes a heating element 100 having a heater 110 and an outer cover member 200 rotatably disposed on the outer surface of such heating element 100. The outer cover member 200 has an insert 210 disposed circumferentially c to transfer the heat generated by the heater 110, 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.

[0116] 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 adding constituent elements within the same spirit, and these should also fall within the spirit of the present invention.
