Description

  The present invention relates to a radiant heater that performs heating with radiant heat.

  Conventionally, this type of radiant heater includes, for example, an electrothermal film provided on the back of a ceramic plate, and heats the ceramic plate by energizing the electrothermal film to generate heat, thereby generating far infrared rays (for example, patents). Reference 1).

Further, as another configuration, it can be seen that far infrared rays are generated by applying a heating wire to the entire surface of the glass plate and heating the glass plate with the heating wire.

  However, in the former radiant heat generating configuration, a conductive electrothermal film has to be uniformly applied on the ceramic plate, and there is a problem that the manufacturing cost is inevitably increased.

  Moreover, in the latter radiant heat generation configuration, it is difficult to apply heating wires on the entire surface of the glass plate and uniformly heat it, which still requires a lot of man-hours for manufacturing, and there are problems in terms of cost, A period is required.

  For example, without applying an electrothermal film or applying a heating wire to a radiator such as a ceramic plate or a glass plate, the radiator and the heating wire are configured separately, and these are stacked to radiate the heat by contact. However, it is difficult to make sure that the radiant and heating wire, which are separate parts, are in full contact with each other. When the parts are deformed, the original function is lost.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a radiant heater that is easy to manufacture and that effectively generates radiation.

  In order to solve the conventional problems, a corrugated plate is disposed on the back surface of the radiator, and a planar heating element is interposed between the radiator and the corrugated plate, and the corrugated shape of the corrugated plate causes a planar shape. The heating element is configured to be pressed against the radiant body, and the corrugated sheet is a reinforcing plate attached to the body case and the back portion thereof is held.

  The radiant heater according to the present invention is configured to press a planar heating element against the radiating body with a corrugated plate provided in front of a reinforcing plate fixed to the cabinet, so that a general planar heating element such as a mica heater is used. Etc. can be used, and even radiant heat can be dissipated, and comfortable heating is possible.

  Further, since the planar heating element only needs to be pressed against the radiant body, the manufacturing is simplified, which is advantageous in terms of quality and cost.

In the first invention, a corrugated plate is disposed on the back surface of the radiator, and a planar heating element is interposed between the radiator and the corrugated sheet, and the planar heating element is radiated by the corrugated shape of the corrugated sheet. The corrugated plate is configured to be pressed against the body, and the corrugated plate is a reinforcing plate attached to the body case and the back portion thereof is held.

  Therefore, it is possible to use a general planar heating element such as a mica heater, so that it can be manufactured at a low cost. Further, the size and assembly are varied, the thermal expansion and contraction of parts, and the impact during transportation. Even if deformation due to the above occurs, the planar heating element can be reliably pressed against the radiator, and uniform radiation heating can be realized.

  In the second invention, in particular, the corrugated sheet of the first invention is fixed to the reinforcing plate at the center. Thereby, the thermal expansion or contraction of the corrugated sheet becomes free, and the planar heating element can be reliably pressed against the radiator.

  In the third aspect of the invention, in particular, in the corrugated sheets of the first and second aspects, the corrugation is set higher toward the center. Therefore, even if the radiator is curved by being attached to the airframe, there is no gap between the central heating element and the planar heating element, and uniform radiation can be realized.

  In the fourth invention, in particular, in the corrugated sheet of the third invention, a plurality of corrugated sheets are provided, and the corrugated shape of the corrugated sheets is set to be higher as the central corrugated sheet.

  In the fifth invention, in particular, in one of the first to fourth corrugated plates, the corrugated plate is formed of a metal material having a spring property.

  In the sixth aspect of the invention, in particular, the sheet heating material of the third aspect of the invention is integrally sandwiched between a heat equalizing body and a fixed plate.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

  That is, each end of the corrugated plate 3 is set as a free end, so that no problem occurs even if thermal expansion or contraction occurs.

  A sheet heating element 5 is sandwiched between a sheet heating element 5a such as a mica heater between a heat equalizing body 5b and a fixed plate 5c, and is crimped integrally with a rivet 5d. Here, the material of the soaking body 5b is excellent in heat conduction such as aluminum.

  The planar heating element 5 is disposed between the radiator 6 and the corrugated plate 3, and is pressed against the radiator 6 by the elastic force of the corrugated plate 3.

  Reference numeral 7 denotes a leg portion fixed to the bottom surface of the fuselage case 1, and a caster 8 is provided on the lower surface thereof so as to be freely movable.

  About the radiation heater comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

Now, when the sheet heating material 5a is energized to generate heat, the heat is transmitted. Since the soaking body 5b is made of a material having excellent heat conduction such as aluminum, the entire surface is heated uniformly,
Accordingly, the temperature of the radiator 6 also rises uniformly, and radiant heat (far infrared rays) is emitted from the entire surface.

  Since the sheet heating element 5 is located between the radiator 6 and the corrugated plate 3 and pressed against the radiator 6 by the elastic force of the corrugated plate 3, the heat of the heat equalizing body 5b is reliably radiated. It is transmitted to the body 6 to increase the radiation efficiency.

  Moreover, even if the sheet heating element 5 is thermally expanded, each end of the corrugated plate 3 is set as a free end. Therefore, even if thermal expansion or contraction occurs, the wave shape follows and presses over the entire surface. Then, the planar heating element 5 is securely brought into pressure contact with the radiator 6.

  And the corrugated sheet 12b arrange | positioned in the center part makes the height of a corrugated height higher than the other corrugated sheets 12a and 12c. Of course, the planar heating element 5 is disposed between the corrugated plates 12, 12 b, 12 c and the radiator 6.

  In the above configuration, the planar heating element 5 is pressed against the radiator 6 by the three corrugated plates 12a, 12b, and 12c, so that the heat of the heat equalizing body 5b is reliably transmitted to the radiator 6.

  However, as described in the second embodiment, when fixing the radiator 6 to the body case 1, as the simplest means, as shown in FIG. 4, the upper presser 1 a that fixes the upper end to the body case 1 is used. The lower presser 1b inserted and applied to the lower end of the radiator 6 is fastened with a screw (not shown) to the bottom surface of the body case 1 to fix it with scissors. In this case, as shown in FIG. There is an allowance for fixing, and accordingly, the radiator 6 is bent forward.

However, in the configuration of the present embodiment, the corrugated plate 12b disposed at the center is another corrugated plate 12a.
