Description

  The present invention relates to a ceiling-hanging electric heating device, and more particularly to a ceiling-hanging electric heating device that heats a heat radiating portion and radiates far infrared rays to heat.

In the interior of a house such as a house, an electric heating device (electric heater) is installed to perform heating.
As shown in FIG. 4, the electric heating device 101 is, for example, a ceiling type that is suspended from the ceiling of a room of a building, and has a heat radiating portion 102 that heats and radiates far infrared rays from the heat radiating surface 102A. In some cases, heating is performed by the high temperature air from the heat radiating portion 102, and the main body exterior member 105 having the heater main body 103 and the main body side plate 104 which protrudes sideward than the heat radiating portion 102.
As an electric heating apparatus, there exist prior art documents as follows, for example.

  The far-infrared electric heater according to Patent Document 1 leaves hot convection rising along the heat dissipation surface on the front side of the heat generating body away from the exterior member (exterior frame) on the upper part of the storage case holding the heat generating body (heat dissipation portion) It is the structure provided with the wedge member for guiding in the direction.

  However, in the electric heating apparatus 101 shown in FIG. 4, when the high temperature air generated at the heat dissipation surface 102A of the heat dissipation portion 102 moves upward, the space between the heater main body 103 and the main body side plate 104 of the main body exterior member 105 The high temperature air enters the space D on the inner side of the main body side plate 104 from the gap S (indicated by R in the two-dot chain line in FIG. 4), which may cause the heater main body 103 to become hot and to be damaged. In addition, there is a need to improve the function deterioration of the heater main body 103 earlier.

  Therefore, it is an object of the present invention to provide a ceiling-hanging type electric heating apparatus that prevents the heater body from being damaged by high temperature and prevents functional deterioration of the heating body.

  According to the present invention, there is provided a ceiling-hanging electric type comprising: a heater main body having a heat radiating portion which heats and radiates far infrared rays from a heat radiating surface; and a main body exterior member having a main body side plate projecting laterally from the heat radiating portion. The heating device is characterized in that a side surface heating prevention plate is provided at a peripheral portion of the heater main body for releasing the high temperature air from the heat radiating portion side to the outside of the main body side plate.

  According to the present invention, since the side surface heating prevention plate dissipates the high temperature air from the heat radiation portion side to the outside of the main body side plate, the high temperature air does not enter the inner side of the main body side plate and the heater main body becomes high temperature and is destroyed. As a result, the functional deterioration of the heater main body can be suppressed.
