When installed in the upper and lower layers, two upper and lower air layers are interposed between the combustion unit 50 and the floor surface F. As a result, the heat of the combustion unit 50 is blocked by the two air layers and is not easily transmitted to the floor surface F. Therefore, in the heating apparatus 1, while the main body apparatus 20 is directly attached to the lower plate 10, the rise in floor surface temperature can be suppressed.

And by attaching the main body apparatus 20 directly to the lower plate | plate 10, a number of parts can be decreased and manufacturing cost can be reduced.
Moreover, by attaching the main body device 20 directly to the lower plate 10, dust can be prevented from entering between the main device 20 and the lower plate 10.
Moreover, since the main body apparatus 20 and the lower plate 10 are connected at the time of manufacture, it is not necessary to adjust the inclination of the main apparatus 20 with respect to the lower plate 10 when the heating device 1 is installed on the floor surface F. The device 1 can be easily installed.

  In the heating device 1 of the present embodiment, as shown in FIG. 4, when the blower 60 blows air, air flows into the upper space S <b> 1 from each opening 47 of the base member 40, and the air in the upper space S <b> 1 flows into the vent 11 d. Is discharged into the room. Thereby, since the temperature rise of upper side space S1 can be suppressed, the heat-shielding effect by upper side space S1 and lower side space S2 can be heightened.

Further, in the heating device 1 of the present embodiment, the air flowing into the upper space S1 forwards due to the air flowing into the upper space S1 from the opening 47 behind the combustion unit 50. Thereby, since an intake action occurs in the opening 47 in front of the combustion unit 50, high-temperature air in front of the combustion unit 50 can be discharged from the opening 47 through the upper space S1 and the vent hole 11d.
Moreover, in the heating apparatus 1 of this embodiment, warm air can be discharged | emitted from the vent hole 11d toward the same direction as the heat radiation direction.

  In addition, since the projection part 11e is formed in the ventilation hole 11d, the dust which tries to enter the ventilation hole 11d from the exterior of the exterior member 30 can be blocked | interrupted by the projection part 11e.

  In the heating device 1 of the present embodiment, as shown in FIG. 3, the lower end portion of the air guide portion 46 of the base member 40 is inserted into the concave portion 11 b formed on the upper surface 11 a of the mounting base 11 of the lower plate 10. Therefore, the heating device 1 can be reduced in size.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention.

  As shown in FIG. 4, the heating device 1 of the present embodiment is configured such that air flows through the upper space S <b> 1 of the base member 40, but the air in the exterior member 30 does not flow into the upper space S <b> 1. You may comprise.

  In the heating device 1 of the present embodiment, as shown in FIG. 3, the lower surface of the base member 40 is open, but the lower surface of the base member 40 may be closed.
