Since the heaters described in Patent Documents 1 and 2 use hot water, a large amount of heat is dissipated when flowing, and the heat dissipation panel cannot be efficiently heated, so that the heat efficiency is not good. In addition, this heater not only generates air convection to dissipate heat, but also dissipates heat from the outer panel of the heat dissipation panel and the first cover body provided on the outside of the tubular member, and rapidly indoors. It could not be said that it was suitable for warming.

Therefore, an object of the present invention is to provide a heater that can heat the room with high thermal efficiency and can heat the room rapidly.

The heater of one embodiment of the present invention is a pair of a flat plate-shaped heat-dissipating panel in which a plurality of through-hole-shaped air passages extending in the vertical direction are arranged in parallel and a pair of heat-generating panels arranged so as to be sandwiched between both sides of the heat-dissipating panel.

More specific examples of the ceramic heater include an alumina-based ceramic heater and a silicon nitride-based ceramic heater.

In the present embodiment, the planar heating element 10 has a configuration in which a conducting wire (not shown) is arranged on a rectangular flat plate-shaped heating portion, and the heating portion has substantially the same area or one size smaller than the flat portion 9c of the heat dissipation panel 9. They are stacked as an area, and a pair of heat dissipation panels 9 are sandwiched and fixed from both sides.
From the viewpoint of heat conduction efficiency, it is preferable to directly contact and fix the planar heating element 10 and the heat radiating panel 9 without any intervention.

As shown in FIG. 3 or 4, the fixture 11 is a piece material having a U-shaped cross section in which both longitudinal edges of a rectangular plate material are bent. In this embodiment, two pairs of heat dissipation panels 9 are used. And the planar heating element 10 is sandwiched and fixed.

The heater 1 can be operated, for example, as follows.
Turn on the ON / OFF switch of the heater 1 to start it. As a result, the planar heating element 10 is energized, and the temperature of the planar heating element 10 begins to rise. Since the planar heating element 10 is directly superposed on the heat radiating panel 9, the heat of the planar heating element 10 is conducted to the heat radiating panel 9. The temperature of the entire heat radiating panel 9, that is, the fin portion 9a, the flat surface portion 9c, and the side end face portion 9d rises, and the air in the ventilation passage 9b is warmed. The warmed air rises in the ventilation passage 9b, is discharged from the opening at the upper part of the heat radiating panel 9, and is sent out from the air outlet 5 via the guide portion 12. At this time, due to the chimney effect, air is sucked from the suction port 8 of the bottom surface 2e, flows through the ventilation passage 9b from the opening at the bottom of the heat dissipation panel 9, is sequentially warmed, and is sent out from the opening at the top. Is released from. In this way, the air circulates to warm the surroundings of the heater 1.

The heater 1 is safe without using fire, and the heat generated by the pair of planar heating elements 10 provided on both flat surface portions 9c of the heat radiating panel 9 is efficiently transferred to the heat radiating panel 9. It can warm the air and has good thermal efficiency.
Further, if the width of the ventilation passage 9b is narrowed, the flow velocity of the warmed air in the ventilation passage 9b becomes high, and the surroundings of the heater 1 can be rapidly warmed.

By using the clip-shaped fixture 11, not only the heat radiating panel 9 and the planar heating element 10 can be easily fixed, but also the heat radiating panel 9 and the planar heating element 10 can be brought into direct contact with each other. It is possible to prevent loss and increase thermal efficiency.
