Recently, it is being considered to use this radiant heater near the human body or to attach it to various devices. In the case of an air circulation type heating device such as a fan heater, the shape is limited and the size is increased, for example, it is necessary to combine it with a blower, and it cannot be simplified. In addition, in the case of a radiant heater, it is of course possible to prevent electric shock, but it is also an issue to prevent burns caused by the user's touch and to minimize the heat effect on other equipment. .. Therefore, it is necessary to keep the internal temperature and the surface temperature of such a radiant heater at about one hundred and several tens of degrees Celsius. On the other hand, since the amount of heat radiated is proportional to the fourth power of the temperature of the radiant surface, the temperature of the radiant surface of the radiant heater cannot be sufficiently heated unless the temperature of the radiant surface is raised as much as possible. Here is the dilemma of safety and heating capacity. In addition, in these days when energy saving is called for, it is also required to obtain the maximum warmth with the minimum power. From this point of view, it is difficult to realize a simple non-contact heating device.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the first embodiment will be described with reference to FIGS. 1 to 5. The configuration of the heating unit 10 in the first embodiment will be described. In the first embodiment, as the heating unit 10, a planar heater made of a heater element 1 made of a cord-shaped heater and a base material 9 is used. The heater element 1 has a configuration as shown in FIG. First, there is a core wire 3 made of an aromatic polyamide fiber bundle having an outer diameter of about 0.2 mm, and on the outer circumference of the core wire 3, five conductor strands made of a hard tin-containing copper alloy wire having a wire diameter of 0.08 mm. A structure in which 5a is aligned is wound in a spiral shape with a pitch of about 1.0 mm. An insulating coating 5b containing silicone formed by applying and drying an alkyd silicone varnish (alkyd: silicone = 50: 50) is formed on the conductor wire 5a with a thickness of about 5 μm. The outer diameter of the heater element 1 configured in this way is 0.38 mm. Further, on the outer periphery of the heater element 1, a polyethylene-based resin composition is extruded and coated with a thickness of 0.13 mm to form a covering portion 7. The covering portion 7 can be melted by a predetermined heat and fused to another member. The finished outer diameter of the heater element 1 including the covering portion 7 is 0.64 mm.

The heater element 1 having the above configuration may be adhered to and fixed to the base material 9. The base material 9 in the first embodiment is made of a polyurethane foam resin having an apparent density of 0.05 g / cm ³ , (JIS K7222 compliant), a hardness of 30 (JIS K6400-2 compliant), a length of 240 mm, a width of 320 mm, and a thickness of 8 mm. .. Such a base material 9 has a desired shape by a known method such as die cutting.

Next, a configuration will be described in which the heater element 1 is arranged on the base material 9 in a predetermined pattern shape and adhered / fixed. FIG. 3 is a diagram showing a configuration of a hot press type heater manufacturing apparatus 13 for pressurizing and heating a base material 9 on which a heater element 1 is arranged. First, there is a heater pattern jig 15, and a plurality of anchoring mechanisms 17 are provided on the heater pattern jig 15. As shown in FIG. 4, the anchoring mechanism 17 includes a pin 19, which is inserted from below into a hole 21 drilled in the hot press jig 15. A retaining member 23 is attached to the upper portion of the pin 19 so as to be movable in the axial direction, and is always urged upward by a coil spring 25. Then, as shown by a virtual line in FIG. 4, the heater element 1 is arranged in a predetermined pattern shape while hooking the heater element 1 on the locking member 23 of the plurality of locking mechanisms 17.

Returning to FIG. 3, the press plate 27 is arranged so as to be able to move up and down above the plurality of locking mechanisms 17. That is, the heater element 1 is arranged in a predetermined pattern shape while being hooked on the engagement member 23 of the plurality of engagement mechanisms 17, and the base material 9 is placed on the heater element 1. In that state, the press plate 27 is lowered to heat and pressurize the heater element 1 and the base material 9. In lowering the press hot plate 27, it is necessary to design so that the compression amount of the base material 9 is at least larger than the outer diameter of the heater element 1. As a result, the base material 9 is compressed, and the heat fusion layer 7 of the heater element 1 is fused to bond and fix the heater element 1 and the base material 9. During heating and pressurization due to the descent of the hot press hot plate 27, the locking members 23 of the plurality of locking mechanisms 17 move downward against the urging force of the coil spring 25. In the present embodiment, after that, the base material 9 is turned over, and heating and pressurization is further performed by a press hot plate 27 from the surface on the side where the heater element 1 is arranged. As a result, both sides of the heating portion 10 become flat, and it is possible to prevent a gap from being formed when the heat insulating material 41 and the warm air storage member 30 are attached.

Next, the warm air storage member 30 is attached to the surface of the base material 9 of the heating unit 10 where the heater element 1 is not arranged. The warm air storage member 30 in the present embodiment is made of black paper having a length of 240 mm, a width of 320 mm, and a thickness of 5 mm. In the present embodiment, the warm air storage member 30 and the heating unit 10 have the same vertical and horizontal dimensions and the same main surface shape, and the warm air storage member 30 holds one surface of the heating unit 10. It is completely covered. The warm air storage member 30 has a partition wall 31 and a warm air storage section 33 separated by the partition wall 31, and the warm air storage section 33 has an opening 35. Further, on the main surface of the warm air storage member 30, partition walls 31a parallel to the long side direction are arranged at intervals of about 3 mm, and wave-shaped partition walls 31b are arranged so as to connect adjacent partition walls 31a to each other. It has a shape similar to that of so-called corrugated cardboard with cross sections arranged side by side. The thickness of the partition wall 31 (31a and 31b) is 0.3 mm. Further, the partition wall 31a is not perpendicular to the main surface of the warm air storage member 30, but is arranged at an angle of about 30 degrees. Therefore, although the warm air storage member 30 is formed with a gap that can serve as the warm air storage section 33, it cannot be seen through the opposite side from the direction perpendicular to the main surface of the warm air storage member 30. That is, when the partition wall 31a is projected onto the plane of the heating portion 10, the plane of the heating portion 10 is covered by the projection of the partition wall 31a. The volume of the warm air storage section 33 is about 30 mm ³ , and the area of the opening 35 is about 6 mm ² .

When the heating unit 10 and the warm air storage member 30 are attached, an adhesive layer (not shown) may be formed on the heating unit 10, the warm air storage member 30, or both. The adhesive layer may be formed by using an adhesive tape, an adhesive or the like. Further, for the formation of the adhesive layer, it is preferable to form an adhesive layer consisting only of an adhesive on the release sheet in advance, and transfer the adhesive layer from the release sheet to the surface of the heating unit 10.

The first heat insulating material 41 can be arranged on the surface of the base material 9 of the heating unit 10 on which the heater element 1 is arranged. The first heat insulating material 41 has a planar shape with a length of 240 mm, a width of 320 mm, and a thickness of 5 mm, an apparent density of 0.17 kg / m ³ , (JIS-K6401 compliant), and a hardness of 8N (JIS-K6301 compliant). ) Made of foamed silicone resin. In the present embodiment, the first heat insulating material 41 and the heating unit 10 have the same vertical and horizontal dimensions and the same main surface shape, and the first heat insulating material 41 is one of the heating units 10. It is in a state of completely covering the surface. Further, a metal layer (not shown) made of aluminum or the like is formed on one surface of the first heat insulating material 41. Such a first heat insulating material 41 is formed into a desired shape by a known method such as die cutting.

Further, another second heat insulating material 42 can be arranged on the surface of the first heat insulating material 41 on the side not in contact with the heater element 1. The second heat insulating material 42 is a planar three-dimensional structure having a length of 240 mm, a width of 320 mm, and a thickness of 5 mm, and is made of polypropylene resin. The second heat insulating material 42 has a structure in which the space between the two flat plates is supported by a countersunk wall, and is a so-called plastic corrugated plastic.

The warm air storage member 30, the heating unit 10, the first heat insulating material 41, and the second heat insulating material 42 may be stacked and the outer peripheral portions thereof may be fixedly held by the fixing material 45 made of an adhesive tape.

By performing the above operation, the heating device 51 as shown in FIGS. 1 and 2 can be obtained. Note that FIG. 2 is an enlarged cross-sectional view showing a main part of FIG. Further, in FIG. 1, a part of the warm air storage member 30, the heating unit 10, and the first heat insulating material 41 is cut out and displayed, but in reality, the warm air storage member 30, the heating unit 10, and the first heat insulating material are shown. The material 41 and the second heat insulating material 42 are stacked in the same shape.

Regarding the heating device 51 obtained as described above, both ends of the heater element 1 are drawn out and connected to a lead wire (not shown), and the lead wire leads to the heater element 1, the temperature control device (not shown), and the heating device 51. , Connector (not shown) is connected. The temperature control device is arranged on the heater element 1 and controls the temperature of the radiant heater by the heat generated by the heater element 1. Then, it will be connected to a power source (not shown) via the above-mentioned connector.

The heating device 51 thus obtained can be arranged with the surface where the warm air storage member 30 is present facing down. As a result, the air warmed by the heating unit 10 is held in the warm air storage section 33. Then, when a heated object such as a human body approaches, a flow of air or a pressure change in the surroundings occurs, warm air is discharged from the opening 35, and the heated object is warmed by this warm air. Especially for the human body, this kind of warming feels very comfortable. The operation and effect of the heating device 51 according to the present invention can be described as follows. First, since the warm air storage member 30 has a heat storage function, a heat amount exceeding the power consumption per unit time is discharged as a temporary heat amount at the required timing, so that a high heat collection effect can be obtained with low power consumption. Obtainable. In addition, since warm air is discharged due to the flow of air and pressure changes in the surroundings when an object to be heated such as the human body approaches, it is possible to efficiently collect heat only when the human body or the like approaches, and the human body is separated. Occasionally, heat storage will start automatically, and heat storage and warm air discharge will be automatically switched. Further, since the heat is stored by storing warm air, the heat loss due to the convection of air is small, and the temperature in the vicinity of the heating unit 10 can be efficiently raised, thereby improving the effect of heating by radiation. be able to. Further, in terms of safety, since the heating unit 10 is insulated by the warm air storage member 30, the temperature is not high enough to cause burns even if the heating device 51 is directly touched.

On the other hand, if the heating device 51 in the present embodiment is arranged with the surface where the warm air storage member 30 is present facing up, the effect of the present invention cannot be achieved. With such an arrangement, the air warmed by the heating unit 10 rises, so that it is not held in the warm air storage section 33 and is immediately discharged from the opening 35. Further, the heating device 51 in the present embodiment can be arranged, for example, by attaching it to a vertical surface, a curved surface, or the like, but in that case, the orientation is such that the opening 35 is on the lower side of the warm air storage section 33. Must be placed in.

The temperature of the heating device 51 according to the first embodiment obtained as described above was measured by the measurement method shown below. In an environment where the room temperature was 0 ° C., the heating devices 51 were arranged at a predetermined distance so as to face the thermocouple. The heating device 51 is attached to a wall surface whose main surface is perpendicular to the horizontal plane, and the opening 35 is arranged so as to face downward. In that state, the heating device 51 was energized so as to have an output of 60 W, held for 30 minutes, and the temperature change during this period was measured. The distance between the thermocouple and the heating device 51 was set to 4 types of 0 mm, 50 mm, 100 mm, and 150 mm. With respect to the first embodiment, the one in which the openings 35 are arranged so as to face upward is referred to as the comparative form 1, and the one without the warm air storage member 30 is referred to as the comparative form 2, and the temperature is measured in the same manner as described above. Table 1 shows the temperatures obtained by these temperature measurements after holding for 30 minutes.

In addition, a sensory test was also conducted on the heating devices according to the first embodiment, the comparative form 1 and the comparative form 2. First, in an environment where the room temperature was 0 ° C. and there was no wind, the heating device 51 was arranged in the same manner as in the above temperature measurement, and in that state, the heating device 51 was energized so as to have an output of 60 W and held for 10 minutes. Then, the subject inserted the palm of his right hand at a distance of 100 mm from the heating device 51 and held it for 5 seconds. The heating devices according to the first embodiment, the comparative form 1 and the comparative form 2 were subjected to such a test on 10 subjects, and the warming order was answered. The order of the tests of the first embodiment, the comparative form 1 and the comparative form 2 was random for each subject. Table 1 also shows the total score of 10 people, with the warmest one being 3 points, the second warmest one being 2 points, and the third warmest one being 1 point.

As shown in Table 1, at points 50 mm, 100 mm, and 150 mm away from the heating device 51, the temperature according to the first embodiment was the highest, and it was confirmed that the heating effect was high. Further, at 0 mm, that is, on the surface of the heating device 51, the temperature according to the first embodiment was 65 ° C. or lower. This is not the temperature at which you will get burned immediately even if you make direct contact. In ISO 1372-1: 2006, the threshold value for the relationship between the contact time and the temperature of the burn is 65 ° C when the material is ceramic, glass and stone, and 70 ° C when the material is plastic, for the contact time of 10 seconds. It is supposed to be. Also, in the sensory test, the heating device according to the first embodiment scored the highest, and 8 out of 10 responded that it was the warmest. As described above, it was confirmed that the heating device according to the first embodiment is safe and can efficiently bring about sensory warmth.

The present invention is not limited to the above embodiment. First, as the configuration of the heater element 1, for example, not only the cord-shaped heater as in the above embodiment but also various other types of cord-shaped heaters can be used. For example, when flexibility and tensile strength are taken into consideration, the core wire 3 used in the above embodiment is effective, but the core wire 3 is not used, and a plurality of conductor strands are aligned or twisted together. It is also possible to assume it. Further, when increasing the rate of temperature rise, it is conceivable to use a nickel-copper alloy wire as the conductor strand 5a. Further, in the above embodiment, the insulating film 5b is applied to the conductor wire 5a, but it is also conceivable that the insulating film 5b is not applied. Further, various cord-shaped heaters can be selected with reference to the above-mentioned Patent Document 2 and the like. Further, the present invention is not limited to the cord-shaped heater, and various heater elements such as a planar heater, a tubular heater, a film heater, a lamp heater, a carbon heater, and a hot water pipe can be used.

In the present invention, the heater element 1 can be directly arranged on the warm air storage member 30, and in that case, a form in which the base material 9 is not used can be considered. Further, as the base material 9, a material such as the first heat insulating material 41 or the second heat insulating material 42, a film-shaped material such as a resin, a metal foil, or the like can be used. For example, various polymer foams such as foamed resin sheets and foamed rubber sheets made of various materials can be considered. Further, depending on the characteristics such as heat insulating property according to the purpose, the state of the bubbles is changed to closed cells or open cells, and the foaming rate, hardness, and the material to be used are selected. Materials include polyurethane resin, chloroprene rubber, silicone resin, silicone rubber, neoprene rubber, diene rubber, nitrile rubber, natural rubber, polyethylene resin, polypropylene resin, vinyl chloride resin, ethylene-vinyl acetate copolymer, melamine resin, etc. , Various resins, rubbers, thermoplastic elastomers and the like may be selected. The metal foil may be selected from various types such as aluminum foil, copper foil, silver foil, stainless steel foil, and those coated with these foils. It is also conceivable to use a non-woven fabric or a woven fabric as the base material 9. Further, a plurality of base materials 9 may be laminated and used, and in this case, different materials or different porosities may be used for each base material 9.

By forming the metal layer on the surface of the base material 9 and the first heat insulating material 41 on the side close to the heater element 1, the heat of the heater element 1 is uniformly transferred to the entire surface of the heating device 51, which is preferable. As the material of the metal layer, for example, aluminum, copper, silver, gold and the like having good thermal conductivity are preferable. The metal layer is formed by various methods such as vapor deposition, spraying, and sticking of a foil with an adhesive or an adhesive tape.

Further, for example, a mode in which an adhesive layer is formed on the outer periphery of the heater element 1 and adhered to the base material 9 or the like, or a mode in which the heater element 1 is sandwiched and fixed by the base material 9 or the like having an adhesive or the like formed on the surface thereof. A mode in which the heater element 1 is fixed to the base material 9 or the like by sewing, a mode in which the side of the base material 9 or the like is melted to fuse and fix the heater element 11, or an adhesive is applied to a portion where the heater element 1 is arranged. It is conceivable that the heater element 1 is formed and adhered / fixed to the base material 9 or the like.

By using various heat insulating materials such as the first heat insulating material 41 and the second heat insulating material 42, it is possible to prevent heat transfer to the side opposite to the object to be heated and improve the thermal efficiency. As the heat insulating material, various polymer foams such as a foamed resin sheet and a foamed rubber sheet, and a material having a structure for retaining air for heat insulation, such as a structure in which the flat plates are supported by a countersunk wall, are preferably used. To. Of course, a plurality of heat insulating materials may be used.

As the warm air storage member 30, various forms can be used as long as it has a warm air storage section 33 for holding warm air and an opening 35 for discharging warm air. The warm air storage section 33 may not function as a warm air storage section depending on the position of the opening 35 and the location and orientation in which the heating device 51 is arranged. For example, when the opening 35 is located above the partition wall 31, the warmed air is discharged without being stored, so that the warm air storage section is not used. It is necessary that at least a part of the enclosed space is above the opening 35, and the enclosed space above the opening 35 is the warm air storage section 33.

Further, various shapes of the partition wall 31 can be considered. The shape of the partition wall 31 is also optimally designed depending on the location and orientation in which the heating device 51 is arranged. For example, when the warm air storage member 30 is arranged with the surface on the upper side facing up, as shown in FIG. 6, if the partition wall 31 is bent, warmed air is stored and the warm air storage section 33 is formed. Will be.

In the above embodiment, as in the case where the partition wall 31a is tilted and arranged, when the partition wall 31 is projected onto the plane of the heating portion 10, the plane of the heating portion 10 may be covered by the projection of the partition wall 31. preferable. As a result, the radiant heat from the heating unit 10 easily hits the partition wall 31, and the air in the warm air storage section 33 can be efficiently warmed. In addition, the heating unit 10 is difficult to see from the outside, so that the appearance is good.

The material constituting the warm air storage member 30 is not particularly limited, but it is preferably made of a material having a low thermal conductivity, such as the paper used in the above embodiment. In addition, for example, it can be composed of a cloth material made of various fiber materials, a wood material such as solid wood or laminated wood, a rubber material, a resin material, a foam rubber material, a foam resin material, or the like. It can be made of ceramic or metallic material, but care must be taken in heat conduction. These materials can be appropriately combined, for example, by partially changing the materials, bonding them together, or coating them. In particular, it is preferable to dispose a material having a low thermal conductivity on the surface portion of the warm air storage member 30 that can be touched by the human body. As a material constituting the warm air storage member 30, a material containing a deodorizing catalyst, an antibacterial agent, a heat storage material and the like can be used. It is conceivable to add these to the material constituting the warm air storage member 30, or to apply them to the surface of the warm air storage member 30. Further, the warm air storage member 30 is preferably black in consideration of the radiation efficiency to the object to be heated.

In the above embodiment, the warm air storage member 30 completely covers the heating unit 10, but for example, a form in which a part of the heating unit 10 is not covered is also conceivable. In the present invention, it is sufficient that the warm air storage member 30 substantially covers one surface of the heating portion 10, and it is not necessary to substantially cover one surface until it completely covers all of them. The area to be covered is appropriately designed according to the shape and shape of the heating unit 10 and the warm air storage member 30, the mounting location of the heating device 51, etc., but it is conceivable that the area covers approximately 90% or more of the area of the heating unit 10. Be done. Further, in the above embodiment, the first heat insulating material 41 completely covers the heating portion 10, but for example, a form in which a part of the heating portion 10 is not covered can be considered. In the present invention, it is sufficient that the heat insulating material (for example, the first heat insulating material 41 or the second heat insulating material 42, etc.) substantially covers one surface of the heating portion 10, and substantially covering all of the heating portion 10. You don't need it until you cover it up. The area to be covered is appropriately designed according to the shape and shape of the heating unit 10 and the heat insulating material, the mounting location of the heating device 51, and the like, but it is conceivable that the area covers approximately 90% or more of the area of the heating unit 10.

The heating device according to the present invention can be a cooling device by using the heating unit as a cooling unit. In this case, the warm air storage member in the heating device becomes a cold air storage member, and the cold air storage member has a cold air storage section for holding cold air and an opening for discharging the cold air. Also, since the cold air descends, it is necessary to form an opening above the cold air storage compartment.
