Description

[Detailed Description of the Invention] This invention relates to a hot air heater that blows hot air onto the floor to increase the temperature of the floor indoors.

Conventional heaters make the human body feel warm by heating the air above the floor. With such a configuration, even if the air above the floor is heated, the warm air rises near the ceiling, making it necessary to further heat the air above the floor by adding thermal energy. It was economical.

Therefore, the present invention is designed to eliminate the above-mentioned problems.It not only can warm the air near the floor, but also pulls down the generally high temperature air near the ceiling and uses that air to heat the floor. To provide a warm air heater that is usable, highly economical, and aesthetically excellent without spoiling the atmosphere of a room.

The drawings showing the embodiments of the present application will be described below. In the warm air heater 1, 2 indicates a hollow cylindrical body. As clearly shown in FIG. 1, this cylindrical body 2 is formed in the alcove 3 at a height that can reach the ceiling 5 from the floor 4 (tatami mat surface), and its external shape is usually known. It has a pillar shape similar to the floor pillar. Furthermore, hard materials such as wood and metal are used as the material. The appearance of the hollow cylindrical body 2 is not limited to the above-mentioned floor column shape, but may be columnar with a pattern or color matching the atmosphere of the room in which the hot air heater 1 is installed. Further, its cross-sectional shape is not only round but also rectangular or any other polygonal shape as required. Next, reference numeral 6 denotes an intake port provided at the upper part of the hollow cylindrical body 2, to which a well-known arbitrary filter 7 is attached. Note that this filter 7 may be detachably attached inside the hollow cylinder. Reference numeral 8 denotes an air outlet provided at the lower part of the hollow cylindrical body, and a louver 9 for changing the wind direction, air volume, etc. is attached here, as is well known. Reference numerals 10 and 11 indicate a blower and a heat generating section, respectively, which are mounted and fixed near the air outlet 8 in the hollow cylinder 2. The blower 10 is constituted by a well-known fan motor, and is configured to blow air in the direction of the heat generating section 11. Note that 10' indicates a metal side plate. In the heat generating section 11, 12,1
2 is an electrode, 13 is an insulating spacer, 14, 14, 1
Reference numeral 4 indicates a well-known semiconductor heater, which is exemplified as a heating element sandwiched between the electrodes 12, 12. These semiconductor heaters 14 have a large number of ventilation holes 15, 15, . . . as clearly shown in FIG. , 12', 12'..., respectively. Further, the number of heaters 14 may be two or less or four or more, depending on the need. In addition to the semiconductor heater 14, a well-known nichrome wire or other heat generating member may be used as the heat generating source in the heat generating section 11. Furthermore, the shape of the electrode 12 is not only round as shown in FIG. 3, but also square or other polygonal in accordance with the inner shape of the hollow cylinder 2. Next, 16 is a power switch, and the hollow cylindrical body 2
Although it is provided on the outer wall of the cylindrical body 2, it may be made separate from the cylindrical body 2 and operated from a position separated from the cylindrical body 2. 17 indicates a bottom plate. The electrical circuit described above is connected as shown in FIG. In FIG. 5, reference numeral 18 indicates a power supply plug that is normally inserted into an outlet in a room, and 19 indicates a temperature fuse that is normally installed near a heating element.

To briefly explain the operation of the hot air heater 1 having the above configuration using FIG. 2, the air taken in from the intake port 6 by the rotation of the blower 10 is heated via the semiconductor heater 14. This heated air is blown out from the outlet 8 as warm air. Therefore, due to the above-mentioned effect, the hot air heater 1 installed as a floor pillar in the alcove 3 as shown in FIG. 1 can warm people, for example, on the floor. Moreover, in this case, since the air is sucked in from near the ceiling and blown out onto the floor, the room is efficiently heated.

As mentioned above, in this invention, the hollow cylindrical body 2
The heating element 14 has air blown in from the top of the
Since it is constructed so that it is heated by air and blown into the room from the air outlet 8 at the bottom, it can of course be used for heating the room, and generally the air near the ceiling is heated by the air near the floor. Considering that the temperature is higher than that of air, in the present invention, the warm air near the ceiling is inhaled,
Since the air is blown out to a low-temperature area near the floor, its heating effect is high, and it has the practical effect of raising the room temperature economically. Moreover, even if the structure is such that it sucks in air from a high position near the ceiling and blows it out onto the floor, the exterior shape is pillar-shaped, so even if it is installed in a room, it will not fit into the room. It has an aesthetic effect and can be installed without spoiling the atmosphere. This means that installing conventional heaters, especially between Japan, often threatens to spoil the unique atmosphere between Japan, whereas the hot air heater 1 according to the present invention can create a unique atmosphere between Japan and other areas. It has excellent practical adaptability and can be installed without spoiling the atmosphere.
