  Since the far-infrared heaters of Patent Documents 1 and 2 have an arch shape that allows the body to enter, when only one hand or foot is to be heated intensively, a heater and heated heat are used. A large space is formed between the two parts and it is difficult to obtain a thermal effect. In addition, since the arch is sized, there is a problem that it is difficult to carry and a large storage space is required. Moreover, since it is necessary to form in a arch shape with a laminated body, there exists a problem which the structure of a heater and its manufacture become complicated.

  The far-infrared heater of Patent Document 3 has a drawback that it can only heat feet and calves and cannot locally heat hands, back, waist, and the like. Further, since the surface heater is provided inside each of the side plate and the bottom plate of the housing, the structure is complicated, and since the housing is used, a certain amount of storage space is required.

  Therefore, the present invention provides a far-infrared heater having a compact structure that can heat most of the body locally and is easy to store.

Far-infrared thermal device of the present invention, far-infrared rotatably on both sides of the planar heating element comprises a planar far infrared heater for radiating a reflector that reflects far-infrared rays back side of the polycarbonate plate and the front side of the It is sandwiched between transparent polycarbonate plates and is pivotally mounted on the side of the sheet heating element so that it can be folded. The front-side light transmitting the far-infrared light is formed by attaching a plurality of dome-shaped protrusions having an air layer between the surface-shaped far-infrared heater and spaced apart in the vertical and horizontal directions . It is characterized by being laminated with transparent polycarbonate plates.

  The effects of the present invention are as follows.

(1) Since the reflector can be folded into a flat shape and made compact, it can be stored in a small space.

(2) By forming a plurality of dome-shaped protrusions having an air layer between the planar far-infrared heater, far-infrared radiation can be radiated at a wide angle and overheating is prevented by the air layer. Can do.

(3) Since the far-infrared radiation radiated from the human body is reflected by the reflector, the thermal effect can be promoted.

(4) By using a polycarbonate plate that transmits far infrared rays and is excellent in impact resistance and heat resistance, the far infrared rays can be used efficiently and safely.

(5) Compared to the conventional heater with a heater on the entire surface, both sides are made of reflectors without providing a heater, so there is no need to provide means for supplying electricity to the hinge, so the structure of the hinge is simple In addition, power consumption can be suppressed by the reflector.

(6) By forming a dent in the upper edge of the reflecting plate, it becomes easier to support the armpit when used while being held, and can be heated in an easy posture.

  An embodiment of the present invention will be described with reference to the drawings.

  1 shows a far-infrared heater of the present invention, (a) is a front view of a state in which a reflector is opened, (b) is a perspective view thereof, and FIG. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is a perspective view showing a state in which the reflector of the far-infrared heater of the present invention is closed, and FIG. 4 is a diagram showing an example of the usage state of the far-infrared heater of the present invention.

  In FIG. 1, a far-infrared heater is composed of a surface heating element 1 having a planar far-infrared heater 6, and a reflector 2 pivotally attached to both sides of the surface heating element 1 via hinges 3. Composed.

  As shown in FIG. 2, the surface heating element 1 has a planar far-infrared heater 6 sandwiched between a synthetic resin plate 4 on the back side and a synthetic resin plate 5 on the front side. A well-known far infrared heater 6 can be used.

  The synthetic resin plate that holds the far-infrared heater 6 is one that has excellent impact resistance and heat resistance that transmits far-infrared rays. In this embodiment, a polycarbonate plate is used.

  A planar far infrared heater 6 is attached to the polycarbonate plate 4 on the back side via a heat insulating material 7. The heat insulating material 7 prevents heat from escaping to the back side.

  A plurality of dome-shaped projections 9 having an air layer 8 between the far-infrared heater 6 and the far-infrared heater 6 are formed on the front polycarbonate plate 5 in contact with the far-infrared heater 6 at intervals in the vertical and horizontal directions. To do. The dome-shaped protrusion 9 having the air layer 8 can radiate far infrared rays at a wide angle, and the air layer 8 can prevent overheating.

  That is, when a far-infrared ray is irradiated using a carbon planar heating element as the far-infrared heater 6, the far-infrared ray has a feature that the irradiation amount increases in accordance with the amount of heat (temperature). In order to increase the amount of far-infrared irradiation, it is necessary to raise the temperature setting of the heating element. However, since the surface heating element 1 of the present invention is in contact with the human body, there is a possibility of causing low-temperature burns. The surface heating element 1 of the invention is provided with a protrusion 9 so that a space is formed between the surface heating element 1 and the human body, heat can be prevented from being excessively transmitted to the human body, and a comfortable temperature for the human body can be maintained.

Further, far infrared rays are a kind of light rays and have a property of traveling straight, but the surface protrusions 9 cause subtle refraction of the far infrared rays, enabling multidirectional irradiation. Since the surface is bent, irradiation in multiple directions is promoted.

  A controller box 10 for controlling temperature and time is disposed on the surface heating element 1, and a temperature / time setting button, a temperature / time display lamp, and a start / stop button are disposed. The user can operate these buttons to adjust the thermal temperature and usage time.

  The reflectors 2 on both sides of the surface heating element 1 are sandwiched between a mirror-finished plate 13, for example, an aluminum plate, between a back side polycarbonate plate 11 and a front side transparent polycarbonate plate 12. The far-infrared radiation radiated from the human body is reflected by the reflector 2 and the thermal effect can be promoted.

  The far-infrared rays irradiated by the protrusions toward the reflector are bounced off by the mirror-finished reflector 2 and concentrate again in the human body direction. Thereby, it becomes possible to irradiate a human body with far-infrared rays from the side surface only by installing the surface heating element 1 at the center.

  When storing far-infrared heaters, as shown in FIG. 2, the reflectors 2 on both sides can be flattened by folding the reflectors 2 down to the surface heating element side so that the thickness can be reduced and made compact. Can be stored.

  Further, a recess 14 may be formed on the upper edge of the reflecting plate 2 so that the armpits can be easily supported when held and used.

  Next, the usage method of the far-infrared heater of this invention is demonstrated.

  As shown in FIG. 4, when the lower limb 15 is heated, the reflector 2 in a folded state is raised to be U-shaped and the surface heating element 1 is supported by the reflector 2. Next, the lower limb 15 is placed under the reflector 2. Thereafter, the temperature of the controller 10 and a timer are set, the start button is turned on, and heating is started. After the heating is finished, the reflecting plate 2 is tilted to the surface heating element 1 side, folded and flattened, and stored.

  The heater of the present invention can heat not only the heat of the lower limb shown in FIG. 4 but also a surface heating element applied to the chest and abdomen in the sleeping state. In addition, a U-shaped heater is placed on the chair and the surface heating element is placed on the calf. A surface heating element can also be applied to the hips to heat.

The far-infrared heater of this invention is shown, (a) is a front view of the state which opened the reflecting plate, (b) is the perspective view. It is AA sectional drawing of Fig.1 (a). It is a perspective view which shows the state which closed the reflecting plate of the far-infrared heater of this invention.
