Description

The present invention relates to an infrared radiator that enables efficient use of infrared heating effects, an infrared heater having the infrared radiator, and heating equipment.

Heat transfer includes conduction, convection, and radiation. Of these, conduction (eg, heat transfer from the surface of an electric carpet) and convection (eg: heat transfer by warm air from a fan heater) are heat transfer to the heated part by bringing the heat source into contact with the heated part. is there. In the initial stage of these heat transfer, a large heat flow can be made to flow to the heated part, but since the surface temperature of the heated object approaches the temperature of the heat source at an early stage, the part that mainly warms up is limited to the vicinity of the surface, and therefore the heating effect. Does not last long. On the other hand, radiation is a heat transfer in which infrared rays (wavelength 0.78 μm to 1 mm) among the electromagnetic waves emitted by a substance when the substance is heated give vibration energy between molecules of a substance to be heated, and the molecules vibrate to generate heat. Is. Since the electromagnetic wave travels through the human body, it is possible to heat the inside of the body with high uniformity, so-called "from the core of the body". Due to these advantages, infrared panel heaters represented by far infrared panel heaters are widely used.

Conventionally, means for effectively using heat rays (far infrared rays) radiated from a far infrared panel heater have been proposed. For example, Japanese Patent Application Laid-Open No. 09-210387 proposes a far-infrared panel heater that is placed so as to be inclined with respect to the ceiling surface and is immediately warmed by far-infrared rays.
Japanese Unexamined Patent Application Publication No. 2009-295451 proposes a device that efficiently transfers heat from a heat source to a ceramic (far-infrared radiation material) to efficiently generate far-infrared radiation from the ceramic.
However, in Japanese Patent Application Laid-Open No. 09-210387, it is considered that there are many cases in which a plurality of far infrared panel heaters that are inclined with respect to the ceiling surface are required. Japanese Unexamined Patent Application Publication No. 2009-295451 is a proposal for efficiently generating far infrared rays, and does not concern about the radiation direction of far infrared rays.

On the other hand, regarding the radiation direction of far infrared rays, Japanese Patent Laid-Open No. 08-042868 proposes that the far infrared radiation surface of the sheet heating element is formed into a curved surface so that heat can be collected at a predetermined position or dissipated in a predetermined direction. Has been done. However, the direction to collect or dissipate heat is unique, and if a curved surface is formed in the direction to collect heat, only a specific part will be warmed, and if a curved surface is formed in the direction to dissipate, as a result of dissipation, the ability to warm up. It is thought that there will be a problem that weakens.

[Embodiment 1]
FIG. 1 is a three-dimensional perspective view of an embodiment of an infrared radiator 1 according to claim 1. 2 is a cross-sectional shape that appears when the infrared radiator is cut along the line AA in FIG. 1, and has a so-called S-shape. In the three-dimensional perspective view, the upper portion 15 has a structure curved from the back side of the paper in the figure to the front side of the paper, and the lower portion 16 has a structure curved from the front side of the paper in the figure to the back side of the paper. From another perspective, the upper portion 15 has a convex first radiating surface (left surface in FIG. 2) and a concave second radiating surface (right surface in FIG. 2 ). The lower portion 16 has a convex first radiating surface (the right surface in FIG. 2) and a concave second radiating surface (the left surface in FIG. 2 ). The upper portion 15 and the lower portion 16 have a point-symmetrical relationship with respect to the center O of the infrared radiator.

FIG. 1-1 is also a three-dimensional perspective view of an embodiment of the infrared radiator according to claim 1. In the embodiment, similar to the embodiment of FIG. 1, the cross-sectional shape that appears when cut along the line BB of FIG. 1-1 is the S-shape of FIG. 2-1. While the upper portion 15 and the lower portion 16 in FIG. 1 are in a point-symmetrical relationship with respect to the center O, in the embodiment in FIG. 1-1, the upper portion 17 and the lower portion 18 are in a point-symmetrical relationship. There is no. FIG. 2 and FIG. 2-1 show that the infrared radiator according to claim 1 is not limited to the one in which the first emitting surface and the second emitting surface have a point-symmetrical relationship. ..

The effect obtained by forming the infrared radiator in the S-shape when viewed from the lateral direction in this way is described with reference to the infrared radiator according to FIG. 1, which is an embodiment of the infrared radiator according to claim 1, as an example [0014] To [0018].

[Effect of forming infrared radiator in S-shape when viewed from the lateral direction]
The infrared heater 25 of FIG. 4 is an embodiment of the infrared heater according to claim 10, and the heating wire 2 is arranged inside the infrared radiator of FIG. 1 as a heating element. This figure is a perspective perspective view of the infrared heater 25. Since the infrared radiator (the infrared heater 25 excluding the heating wire 2) contains a substance that radiates infrared rays, it is heated by the heat generated by the heating wire 2, and when the temperature reaches a predetermined temperature, the infrared rays Emit from the surface. In addition, in this specification, "infrared rays" is not limited to infrared rays in a narrow sense that does not include far infrared rays, but has a broad sense that includes far infrared rays.

FIG. 5 is a cross-sectional shape that appears when the infrared heater 25 is cut along the line C-C in FIG. 4, and shows the heating wire 2. 6 and 7 are enlarged views of the portion 19 and the portion 20 of FIG. 5, respectively.

FIG. 8 shows the emission direction of infrared rays emitted from the portion 19 of FIG. When the infrared radiator is heated by the heating wire and reaches a certain temperature or higher, the infrared radiator emits infrared rays, and the direction thereof is the direction normal to the surface of the infrared radiator. Reference numeral 4 in the figure indicates the radiation direction of the infrared rays emitted from the respective points on the infrared radiation surface of the portion 19 of FIG. 5 from the respective points, and indicates that the infrared rays are emitted in the normal direction. There is.

Then, as shown in [0011], the portion 19 of FIG. 5 is curved from the back side of the paper surface of FIG. 1 to the front side of the paper surface (upper portion 15 of the same figure), so far infrared rays radiated from the back side to the front side. As shown by reference numeral 4 in FIG. 8, the light spreads outward like the light applied to the concave lens.

FIG. 9 shows the emission direction of infrared rays emitted from the portion 20. When the infrared radiator is heated by the heating wire and reaches a certain temperature or higher, the infrared radiator emits infrared rays, but its direction is in the direction normal to the tangent to the surface of the infrared radiator. Reference numeral 5 in the figure indicates the radiation direction of the infrared rays emitted from the points of the portion 20 from the points, and indicates that the infrared rays are emitted in the normal direction.

Then, since the portion 20 is curved from the front side to the back side of FIG. 1 as described in [0011], infrared rays radiated from the back side to the front side are applied to the convex lens as shown by reference numeral 5 in FIG. It concentrates inwardly like the light that is emitted (Fig. 9).

FIG. 10 is a combination of FIG. 8 and FIG. 9, and shows a sectional view taken along line CC of the infrared heater according to FIG. 4 and an infrared radiation direction.

Similarly to FIG. 4, FIG. 4-1 is also an embodiment of the infrared heater according to claim 10, and is a perspective view showing a state in which the heat generating sheet 29 is arranged inside the infrared radiator according to claim 1. .. Reference numeral 30 in FIG. 4-1 is an electrode. When a predetermined voltage is applied to the electrodes 30, the sheet between the electrodes generates heat. The heat generating sheet and the heating wire may be known ones. FIG. 4-4 is a sectional view taken along the line FF in FIG.

FIG. 4-2 is an embodiment of the infrared heater according to claim 11, wherein a heating wire is arranged as a heating element adjacent to the infrared radiator according to FIG. FIG. 5A is a sectional view taken along the line D-D of FIG.

Similarly to FIG. 4-2, FIG. 4-3 is also an embodiment of the infrared heater according to claim 11, and a heat generating sheet is arranged as a heat generating element adjacent to the infrared radiator according to claim 1. 4-5 is a sectional view taken along line GG of FIG. 4-3.

The heating element of the infrared heater according to claim 10 and claim 11 is not limited to the heating wire and the heating sheet described in the embodiment, and only the heating wire and the heating element have the configuration of the infrared heater according to claim 11. It should not be interpreted as a requirement.
In the infrared heater according to the twelfth aspect, the substance that emits infrared rays contained in the infrared radiator may also function as a heating element. In that case, the infrared heater can radiate infrared rays even if it is composed of a single sheet-shaped heating element. Examples of the “infrared emitting substance” that also functions as a heating element include the following.

The effect of the heating equipment according to claim 4 utilizing the effect of the infrared radiator according to claim 1 described in [0014] to [0019] will be described in [0025] to [0027].

The heating equipment 7 of FIG. 12 is the heating equipment according to claim 4, and its structure will be described with reference to FIG. A portion 19 and a portion 20 are formed side by side from top to bottom in the schematic vertical direction of FIG. The casters 9 are casters for facilitating the movement of the heating equipment 7. The caster is an example of defining the normal usage direction of the heating facility, and should not be construed as one requirement of the heating facility 7 according to claim 6. In addition, in the present specification, the “outline” mainly includes a strict meaning and a range included in terms of function and purpose. For example, the approximate vertical direction includes a linear direction centered on the strict vertical direction and slightly inclined with respect to the strict vertical direction.

When the heating wire 2 of the heating equipment 7 of FIG. 11 is energized and the infrared radiator reaches a predetermined temperature, the mechanism described in [0014] to [0019] changes from the “heating equipment front” of FIG. 12 to FIG. Infrared rays are emitted from the surface of the infrared radiator in the direction shown.

In FIG. 11, the infrared rays radiated from the convex surface spread to the outside as described in [0017], so that the infrared rays emitted to the range from the torso of the person to the head are drawn on the left side of the figure. . On the other hand, the infrared rays radiated from the concave surface are concentrated inward as described in [0019], and are radiated mainly to the person's legs while some infrared rays intersect.
As a result, infrared rays are applied to the range from the toes to the head of the person's leg, and the so-called "warming from the core of the body" is obtained by the infrared effect described in [0002] on the entire body of the person. You can

Next, the effect of the heating equipment according to claim 5 utilizing the effect of the infrared radiator according to claim 1 described in [0014] to [0019] will be described in [0029] to [0031].
In the present embodiment, the radiation surface of the infrared radiator that radiates infrared rays is formed in an S shape when viewed from the side, and in the S shape, the infrared rays are perpendicular to the convex surface from the convex surface. As a result of being emitted, the infrared rays are emitted in the direction in which they spread outward, just as the light spreads out from the concave lens, while the infrared rays are emitted from the concave surface of the S-shape perpendicular to the concave surface. Is emitted, so that the infrared rays are concentrated inwardly, as the light is concentrated inwardly from the convex lens. When this mechanism is used in heating equipment and the convex surface of the S-shape is formed on the upper side and the concave surface is formed on the lower side, infrared rays emitted from the convex surface are emitted from the human body, for example, from the waist to the head. It is possible to widely warm the range up to, and the far infrared rays emitted from the concave surface can intensively warm the toes of the legs from the waist. This contributes to the realization of so-called "head cold foot heat" heating, which is ideal for warming the human body.

The heating equipment 8 of FIG. 13 is the heating equipment according to claim 5, and the structure thereof will be described with reference to FIG. An upper portion 15 and a lower portion 16 are arranged side by side from the left to the right in the figure along the schematic horizontal direction of the figure. The casters 9 are casters for facilitating the movement of the heating equipment 8. Note that the caster is an example of defining the normal usage direction of the heating facility, and should not be construed as one requirement of the heating facility 8 according to claim 5.

The room 11 in FIG. 14 is a room in which the heating facility 8 according to claim 5 is installed. The figure shows the room viewed from above. When the far-infrared radiation panel reaches a predetermined temperature by energizing the heating wire 2 (the same figure) of the heating facility 8, from the "front side of the heating facility" of FIG. 13 by the mechanism described in [0014] to [0019], Far infrared rays are emitted from the surface of the infrared heater 25 in the direction indicated by 14.

As a result, far-infrared rays are emitted to the people 12, 13, and 14 in the room shown in FIG. That is, a plurality of people in the room can simultaneously enjoy the so-called "warming from the core of the body" effect of far infrared rays.

Next, using the effects of the heating equipment according to claim 4 and the heating equipment according to claim 5 described in [0025] to [0031], the effects of the heating equipment according to claim 6 are obtained from [0033] to [0036]. ] Will be described.

The heating equipment 10 of FIG. 15 is the heating equipment according to claim 6, and as one embodiment thereof, the heating equipment 10 having the infrared heater 25 according to FIG. 4 will be described. A convex portion 19 and a concave portion 20 are formed side by side in the schematic vertical direction of FIG. The casters 9 are casters for facilitating the movement of the heating equipment 10. The casters 9 are attached to the bottom and side surfaces of the heating equipment 10. The caster is an example of defining the normal usage direction of the heating facility, and should not be construed as one requirement of the heating facility 10 according to claim 6.

If the heating wire of the heating equipment 10 is energized in the installed state of FIG. 15, that is, with the bottom surface shown in the same figure vertically downward, the effects described in [0025] to [0027] can be obtained.

If the heating wire is energized with the heating equipment 10 installed with the side surface shown in the figure vertically downward, the effects described in [0029] to [0031] can be obtained.

That is, a means (caster 9 in this embodiment) that enables the infrared radiation surface formed on the convex portion 19 and the concave portion 20 to be changed to either a substantially vertical direction or a substantially horizontal direction. By providing the bottom surface and the side surface in the same figure, two kinds of effects can be obtained depending on the installation state in the same heating equipment.

Next, the structure and effect of the infrared radiator according to claim 2 will be described in [0038] to [0040].

FIG. 3 is a three-dimensional perspective view of an embodiment of the infrared radiator according to claim 2. The upper portion 23 of the three-dimensional perspective view has a curved shape like the upper portion 15 of FIG. On the other hand, the lower portion 24 has a flat third emitting surface.

When the upper portion 23 of the infrared radiator according to FIG. 3 is used as a convex infrared radiation surface, the infrared rays from the upper portion 23 are radiated in the outward spreading direction as shown in FIG. 3-2. The infrared rays emitted from the portion 24 are emitted in parallel with each other.

When the upper portion 23 of the infrared radiator according to FIG. 3 is used as a concave infrared emitting surface, the infrared rays from the upper portion 23 are emitted in the direction of converging inward as shown in FIG. 3-3. Infrared rays emitted from the lower portion 24 are emitted in parallel with each other.

Whether the upper portion 23 is used as a convex infrared ray emitting surface (FIG. 3-2) or as a concave infrared ray emitting surface (FIG. 3-3) may be determined according to a target situation.

Next, the structure and effect of the infrared radiator according to claim 3 will be described in [0043] to [0044].

FIG. 16-3 is a perspective view of an embodiment 37 of the infrared radiator according to claim 3. 16-4 is a cross-sectional shape that appears when the infrared radiator is cut along a line EE orthogonal to the virtual straight line P of FIG. 16-3. The cross-sectional shape is remarkably different from the cross-sectional shape according to FIG. different. That is, the cross-sectional shape according to FIG. 2 is symmetrical in the vertical direction, whereas the cross-sectional shape according to FIG. 16-4 is clearly asymmetric in the vertical direction. This is because the shape of the infrared radiator according to claim 3 is formed through the process described below.

Reference numeral 36 in FIG. 16 indicates a flat-shaped infrared radiator before being formed. In the figure, virtual straight lines P and Q are virtual straight lines that are not parallel to each other, the virtual straight line P is located on the back side of the paper surface with respect to the infrared radiator, and the virtual straight line Q is located on the front surface side of the paper surface with respect to the infrared radiator. I shall.

Bend in the direction of the arrow. Since the virtual straight line P is located on the back side of the paper surface with respect to the infrared radiator as described above, the upper portion is formed by being bent from the front side to the back side of the paper surface with the virtual straight line P being substantially the central axis. It

Next, in order to form the portion 39 of FIG. 16C, as shown in FIG. Bend in the direction of the arrow on the front side. Since the virtual straight line Q is located on the front surface side of the paper surface with respect to the infrared radiator as described above, the lower portion is formed by being bent from the back side of the paper surface to the front side with the virtual straight line Q being substantially the central axis. It

Since the virtual straight lines P and Q are not parallel to each other, the EE cross-sectional shape of the infrared radiator 37 formed by bending the virtual straight lines P and Q about the central axis is such that the top and bottom are asymmetrical as shown in FIG. 16-4. Becomes

The virtual straight lines P and Q do not have to be straight lines on the same plane, and may be straight lines that are not parallel to each other in the three-dimensional space.

Since the infrared radiator according to claim 3 is formed by bending the infrared radiator around the virtual straight lines that are not parallel to each other as a substantially central axis, the infrared radiators according to claims 1 and 2 Can emit infrared rays in a wide range.
