Description

  The present invention relates to an immediate warming type heating apparatus, and more particularly, to a near infrared immediate heating that can utilize the soft warmth of a carbon lamp or the heat of a halogen lamp while utilizing the characteristics of a conventional heating apparatus that radiates far infrared radiation. A heater is provided.

  As a planar radiator used in a conventional far-infrared heater, a far-infrared heater in which ceramic is coated in a planar shape by plasma spraying is known, and among these, Japanese Patent Publication No. 5-61754 “Far-infrared heater” And a heat-dissipating body in which white alumina is plasma sprayed to a thickness of 50 to 100 μm on the surface of the heating element fixed to the surface of the supporting body, and a short wavelength with a wavelength of 6 μm as a boundary. Disclosed is a far-infrared heater characterized in that the far-infrared infrared radiation intensity is low and the long-wavelength radiation intensity is high on the long-wavelength side. It is used for heating equipment and medical equipment.

  As a product using far-infrared rays, Japanese Patent Laid-Open No. 61-15020 “Far-infrared heating device” uses silver-aluminum alloy powder on the back surface of a heat-dissipating glass plate made of tempered roll glass that is continuously formed with a large number of curved irregularities. A linear heating element is formed by welding in a printed wiring pattern, and the surface temperature of the radiating glass plate is set to 150 to 170 ° C. by energizing the linear heating element so as to generate far infrared rays on the radiating glass plate. A far-infrared heating device characterized by the above is disclosed.

  Furthermore, Japanese Patent Publication No. 2987354 has a rectangular box-shaped casing provided with a back plate on the back surface and an opening on the front surface, formed on both sides of the front surface side less than the opening of the casing and small on the front surface. An alloy made of aluminum, copper, iron or the like on the back surface of the heat-resistant tempered glass plate with a plurality of recesses continuously provided and with the back surface front surface as a flat surface. In a far-infrared heating device in which powder is welded in the form of a printed wiring to provide a linear heating element, and an enamel coating is applied on the heating element on the wire to form a coating layer, the heat-dissipating glass plate has both sides thereof At the both sides of the front side of the casing, it is fixed to the mounting pieces that are bent inwardly, and is attached to the back side of the heat radiating glass plate. A reflecting plate made of aluminum having a gap portion having a function of retaining the property is fixed to the casing, and the reflecting plate is open at the upper and lower surface portions of the radiating glass plate not fixed to the casing. Disclosed is a far-infrared heating device characterized by connecting extension pieces that are expanded outward near the edge.

  However, as described above, as a conventional far-infrared heater, a heater using a heater composed of a plate-like heating element is known, but when a heat-resistant tempered glass or a ceramic member is used as the plate-like material, Had the property of being vulnerable to impacts due to its material properties.

  Also, as the shape of the heating element, in order to increase the heat generation efficiency, in recent years, a device has been devised to increase the generation of far infrared rays by providing a linear circuit by print printing, and it has succeeded in raising the efficiency as such, Conventional objects have often been developed from the viewpoint of how to generate far-infrared rays having a specific range of wavelengths.

In addition, since the amount of heat generated from the linear circuit is high at the center, a conventional far-infrared heat radiation plate cannot prevent warpage with a flat plate-shaped pressure plate, so a pressure plate with an annular bead processed on the pressure plate. Although the use is disclosed in Japanese Patent Application Laid-Open No. 2002-98343, since this presser plate requires an annular bead processing, there is a problem in that the mold itself and the presser plate are expensive to manufacture.
Japanese Patent Publication No. 5-61754 JP-A-61-152020 Patent Publication No. 2987354

  As described above, the conventional far-infrared heaters have been developed mainly to increase the heat generation efficiency by using a plate-shaped heating plate, so the heater itself warms up after the switch is turned on. However, no consideration was given to how long it would take and the energy saving aspect of radiating with less power.

  On the other hand, the carbon lamp has the function of warming the surroundings by generating heat immediately after the halogen heater is turned on, whereas it has the function of heating warmly while emitting soft warmth. There were few uses as a heating appliance for the house.

  The present inventor has intensively studied to solve the problem, and provides a new near-infrared immediate heating heater that can use the immediate heating function of a carbon lamp or a halogen lamp while taking advantage of the characteristics of a conventional far-infrared heater. We were able to.

  That is, the first aspect of the present invention is a heating device body having a rectangular box shape having a back plate on the back surface and an opening on the front surface, and a first heating portion that radiates far infrared rays in the casing of the body. A near-infrared infrared heating / cooling heater characterized by having a second heating section made of a carbon lamp positioned.

  In the second aspect of the present invention, the first heating unit is composed of a far-infrared radiator, a flat heating element, and a holding plate, and among these, the far-infrared radiator is a heat dissipation that generates a far-infrared radiator on the surface of the radiation plate. The flat heating element is a heating element that is integrally formed by sandwiching a heater portion between two upper and lower plate bodies, and further, between the rear plate upper body and the pressing plate. Is a near-infrared infrared heating / heating device according to claim 1, wherein at least two heat insulating materials are sandwiched to control warping of the pressing plate.

The third aspect of the present invention is the far-infrared infrared heating / heating device according to claim 1, wherein the planar heating element increases the thermal conductivity by being pressed at a pressure of 40 g / cm ² or more in the direction of the heat radiating plate. It is.

  According to a fourth aspect of the present invention, there is provided a near-infrared immediate heating heater according to claim 1, wherein the second heating unit uses a carbon lamp having carbon fibers as an inner core material.

  A fifth aspect of the present invention is the far-infrared infrared heating apparatus according to claim 1, wherein the second heating unit uses a halogen lamp.

  In the near-infrared immediate heating / heating apparatus of the present invention, when the switch is turned on, the carbon lamp or halogen lamp as the second heating section is first warmed first, and then the heating element of the first heating section warms the far-infrared radiation plate. In order to perform radiation, the effect of warming the surroundings can be quickly obtained as compared with the conventional heater.

  Moreover, since the said heater can operate a 1st heating part, a 2nd heating part, or these both simultaneously, since it should just adjust temperature according to heating environment, an economical effect is large at an energy saving. Is.

  FIG. 1 is a front view of a heater showing an example of implementation of the present invention. This heater is provided with an opening-type casing 2 in the heater body 1, a first heating section that radiates far infrared rays inside the casing, and a second heating section that radiates heat from a carbon lamp or a halogen lamp. It is what has.

  The first heating unit is combined with the heating element 18, the first heat insulating material, the second heat insulating material, and the pressing plate (not shown) overlapped with the back of the heat radiating plate 13.

  In this case, the heat radiation plate 13 having a length of 25 cm and a width of 40 cm which is fitted to the casing 2 and fixed with screws is made of an aluminum material or a steel material and coated with ceramic powder that generates far infrared rays on the surface thereof.

  Furthermore, it is also possible to provide a negative ion generation part in which a fine ceramic that generates negative ions is applied to a part of the surface of the heat radiating plate 9 in place of the ceramic powder that generates far-infrared rays.

  In this case, in the negative ion generation part, a fine ceramic material is applied to one side or both sides of the heat radiating plate, and in the present invention, a high-purity complete refined by a SOL-Gel process is used as the fine ceramic. Ceramic (trade name) using a semi-permanent pigment that is inorganic and stable even at high temperatures can be used. However, the ceramic is not limited to this as long as it can generate negative ions.

  As a material to replace ceramic, the Superray (trade name), which is a far-infrared high-radiation aluminum functional material, can be used in the present invention. It is a material that is hard to break and has excellent durability, has a high degree of freedom in molding, and has good performance such as curved surfaces and bending by pressing.

  Next, a heating plate (not shown) having a length of 22 cm and a width of 38 cm to be brought into contact with the heat radiating plate 9, as shown in FIG. 3, a stainless steel foil heating element 18, a rear part made of artificial mica having a length of 25 cm and a width of 40 cm. The plate-like body 17 and a similarly manufactured non-illustrated front plate-like body are sandwiched and integrally formed. The heat generating portion 15 has a dense linear circuit connected to a power source. 12 is provided.

  This heating element 18 is a flexible flat heating element produced by integrally molding a plate made of artificial mica and a stainless steel heater element, and improves the adhesion between the stainless steel foil and the plate made of artificial mica. The specially designed material is ultra thin and lightweight, so it is easy to handle and saves space.

  In addition, the stainless steel foil heater element has a uniform temperature distribution due to its planar shape, and has an excellent thermal response due to its ultra-thin type of about 0.1 mm (100 μm), which can save energy. .

  This heating element does not lose flexibility even at an extremely low temperature of −200 ° C. or lower, and also has insoluble and flame-retardant characteristics even at a high temperature of 400 ° C. or higher, and can be used for a long time even at a constant 270 ° C. However, depending on the material of the heat sink, a considerable temperature difference occurs between the central part and the peripheral part.

  Next, a first heat insulating material (not shown) made of ceramic wool having a length of 30 cm and a width of 40 cm is sandwiched between the heating element 18 (particularly the rear plate 17) and the pressing plate, for example, 10 cm in length. It is more preferable that a second heat insulating material (not shown) made of ceramic wool having a width of 20 cm and a thickness of 12 mm is stacked and compressed so that the thickness is reduced by more than half.

  The reason for this is that the heat radiated from the heating element 18 normally passes through a first heat insulating material (not shown) and is transferred to a pressing plate (not shown), and the heat is applied on a flat plate or a convex shape. A certain pressing plate bends in a bow shape. This prevents the formation of a gap when the second heat insulating material is sandwiched between the first heat insulating material and the pressing plate, and heat transfer from the heating element 18 to the pressing plate is small. As a result, the presser plate itself could be a flat body having a length of 25 cm and a width of 40 cm.

  According to the present invention, in the first heating section, in addition to generating the negative ions, far infrared rays and near infrared rays can be generated from a far infrared radiation portion (not shown) of the same heat radiating plate 13.

  As a mechanism for this generation, a heating element 18 composed of a dense linear circuit 16 connected to a power source is provided inside the heating element 18, and a current of 170 W is applied to the upper power terminal portion 14, A current of 450 W flows through the terminal portion 15.

As the dense linear circuit 16, pattern printing is performed linearly as shown in FIG. 3. As an example, the watt density is 0.6 to 0.8 w / cm ² around the center. When the current is passed through the printed material with a density of 0.3 to 0.6 w / cm ^{2 in} other ranges, heat starts to be generated from the center of the heat sink, and accordingly the heat sink surface Heat is transferred to the ceramic powder, and near infrared rays are first generated to enable immediate heating, and then gradually heated from the center to the periphery to generate far infrared rays, but various changes can be made by pattern printing.

  Further, in the case where a negative ion generating part coated with a fine ceramic that generates negative ions is provided on a part of the surface of the heat radiating plate 13 instead of the ceramic powder that generates far infrared rays, the coating part of the fine shellac is provided. Heat is also transmitted to generate negative ions and waves.

  When the surface temperature of the heatsink becomes 210-250 ° C, the controller (not shown) automatically operates to switch off the 150W switch connected to the upper power terminal 10 and only 350W flows. Besides trying to save energy, the surface temperature of the heat sink is 210-250 ° C, so it is possible to uniformly warm a 6-8 tatami room with one heater. Became.

As the ceramic powder applied to the surface of the heat sink 13, a coating material in which at least one ceramic of ZrO ₂ , SiO ₂ , TiO ₂ , Al ₂ O ₃ generating infrared rays is mixed with an organic material is used. Other than the above coating materials can be used as long as they can directly coat the heat sink 9.

  Another feature of the present invention is that a second heating unit made of a carbon lamp or a halogen lamp is provided, and these lamps are set at the lower part of the first heating unit, but both ends of the lamp are fitted to the fixture. Designed to be united and fixed.

  Among these, the carbon lamp uses carbon fiber (made of plant fiber or mineral fiber) for the inner core, so it has the property of warming up immediately when it is turned on, and it is hot like a halogen lamp to emit warm light. There is no such feeling.

  Details of the present invention will be described below with reference to examples, but the scope of the present invention is not limited thereto.
