BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating device in which an electric heater is installed in a storage part projecting on the inside of a waist wall below a window device.

[0002]

2. Description of the Related Art Conventionally, there is no one in which an electric heater is installed in a storage portion projecting on the inside of a waist wall below a window device.
It has been known that a window frame and a frame are provided with a heating element as disclosed in JP-A-3-228991.

[0003]

Therefore, conventionally, there is a problem that the cold air entering through the window cannot be stopped and the temperature distribution in the entire room cannot be made uniform. Furthermore, the one disclosed in the above-mentioned Japanese Patent Laid-Open No. 3-228991 merely prevents dew condensation on the window and cannot stop the cold air entering from the window, thereby making the temperature distribution in the entire room uniform. There was a problem that I could not do it.

The present invention has been made in order to solve the above-mentioned conventional problems, and a glass window is provided by installing an electric heater in an accommodating portion projecting toward the indoor side of a waist wall below a window device. It is an object of the present invention to provide a heating device which can blow out heated air from a position close to to make the temperature distribution in the room uniform and prevent fogging and dew condensation on the glass window.

[0005]

The present invention is formed in the shape of a hollow rectangular box having at least an upper plate, a front plate and a bottom plate on the indoor front surface of the lower wall of the window device to which the glass window is attached. While the storage section is fixed, a partition wall is vertically fixed to the lower surface in the central portion of the upper plate in the longitudinal direction, and a ventilation opening is provided below the partition wall, and an electric heater is provided on the indoor side front surface of the partition wall. And a number of cold air suction holes are formed on the waist wall side from the longitudinal center of the upper plate, and heated air blowout holes are provided on the front plate side from the longitudinal center of the upper plate. The above-mentioned problem was solved by adopting a means of forming a large number of holes and opening an air introduction port on the lower surface of the front plate.

[0006]

According to the present invention having the above-mentioned structure, the electric heater is heated to radiate heat, and the radiated heat heats the room air introduced from the air introduction port and the cold air sucked from the suction hole to blow out the air. Blow out heated air from the hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. A window device 3 having a glass window 2 is disposed above a waist wall 1 of a house.

A storage portion 5 for storing an electric heater 4 having a length substantially the same as the width of the window device 3 is fixedly provided on the front surface of the waist wall 1 on the indoor side.

The accommodating portion 5 is formed in the shape of a hollow rectangular box provided with an upper plate 6, a front plate 7, a rear plate 8, a bottom plate 9 and both side plates 10, and is fixed to the front surface of the waist wall 1 on the indoor side. ing. The rear plate 8 and the side plates 10 may be unnecessary depending on the mounting location.

A partition wall 11 is vertically fixed to the lower surface of the upper plate 6 of the storage portion 5 in the central portion, and a ventilation opening 12 is provided below the partition wall 11, and the partition wall 1 is also provided.
The front plate 7 is attached to the front surface on the indoor side of No. 1 via a fixture 13.
The electric heater 4 is fixedly provided with a space 14 between the electric heater 4 and the electric heater 4.

A large number of suction holes 15 for sucking the cool air descending from the window device 3 are formed on the waist wall 1 side from the central portion in the longitudinal direction of the upper plate 6 on which the partition wall 11 is vertically fixed. On the front plate 7 side with respect to the longitudinal center of the upper plate 6, a large number of blowout holes 16 for blowing the heated air heated by the electric heater 4 are formed, and further on the lower surface of the front plate 7. Has an air inlet 17 for introducing the air in the room.

The electric heater 4 is not particularly limited, but it is preferable to use a sheet heating element 4a coated with graphite carbon that uniformly conducts heat to the entire surface of the panel, and the sheet heating element is used. It is recommended that a heat insulating material 4b made of, for example, high-temperature glass wool is additionally provided on the back surface of 4a so that the radiant heat from the planar heating element 4a is not conducted to the partition wall 11.

Next, the operation of the embodiment will be described. By turning on a switch (not shown), the electric heater 4 is heated and radiates heat as indicated by an arrow in FIG. 2, and the indoor air introduced through the air introduction port 17 and the glass window 2 are radiated by the heat radiation. Along with this, the cold air mixed with the introduced air is heated through the ventilation opening 12 after being sucked down through the suction hole 15 and the heated air heated by the electric heater 4 through the discharge hole 16 is used as an updraft. The heated air that has blown out and is gradually heated by the convection from the window side of the room toward the central portion to make the temperature distribution of the room uniform.
The same cycle is repeated thereafter to raise the temperature of the room.

Further, by heating heated air as a rising airflow from a position close to the glass window 2 to warm the glass window 2, cold outside air entering from the window is shut off, and the glass window 2 becomes cloudy or dew condensation occurs. Since this prevents the glass window 2 from being soiled.

[0015]

As described above, according to the present invention, since the electric heater is installed in the storage part projecting on the room side of the lower waist wall of the window device, the heating by the electric heater is performed. The air is diffused to the center of the room by convection and the temperature distribution becomes uniform, and the cool air that has descended along the glass window enters the storage part from the suction hole provided closer to the window device side than the heating air outlet hole. Because it adopts a configuration that can be sucked into
The cold air suction hole and the heated air blowout hole function independently of each other, and the cold air sucked into the storage portion and the room air introduced from the air introduction port are mixed and immediately heated by the electric heater. Since the cool air from the glass window does not stay in the room, the indoor heating can be accelerated. Further, since the heated air is blown out as an ascending air current from a position close to the glass window to warm the glass window, the window glass is not fogged or dewed.
