In view of this, the present invention provides air outlets at the lower front and lower sides of the casing of the hot air fan, and blows out hot air from one or both of the air outlets. Either the outlet or the side air outlet can be selected as appropriate depending on the installation location and can be connected directly to the connection part of the floor panel without going through a connecting duct, and when heating a wide area. The object of the present invention is to enable both of the air outlets to be connected to the connecting portion of two floor panels without requiring a diverter pipe, thereby simplifying the installation work and improving safety during use. It is something.

Therefore, in the configuration of the present invention, the inside of the casing of the hot air fan is partitioned into a fan chamber and a heat exchanger on the left and right by a partition plate, and the fan chamber has an air outlet that opens into the upper space of the heat exchanger chamber. The heat exchanger chamber includes a burner having a burner section at the bottom and a combustion chamber section at the top, and a heat exchanger connected to the combustion chamber section of the burner. The burner portion of the heat exchanger chamber is shielded from other parts of the heat exchanger chamber by a partition body in a state where the burner portion is communicated with an external intake port opened at the back surface of the casing at a lower space position extending from the back surface of the casing to the center portion on the partition plate side, and The combustion chamber and the heat exchanger are arranged to face the air outlet of the air blower fan,
Furthermore, a front side outlet and a side outlet that communicate with the heat exchanger chamber are provided at the front side lower part and the side lower part of the casing corresponding to the heat exchanger chamber, respectively, and the air is heated from the air outlet of the blower fan. The air supplied to the exchanger chamber is heated in the heat exchanger and the combustion chamber of the oil burner, and is supplied as warm air from the outlet into the floor panel.

Furthermore, when in use, the hot air fan 3 and the series of floor panels 1 are directly connected, and unlike conventional connecting ducts, there is no obstruction to the scaffolding, thereby improving safety. It goes without saying that depending on the installation location, the warm air fan 3 and a series of floor panels 1 may be connected via an auxiliary panel 38, as shown in FIG. 8c.

Furthermore, as can be seen from FIG. 8d, even when connecting both air outlets 25 and 26 of the hot air fan 3 to two sets of floor panels 1' and 1', the front air outlet 25 of the hot air fan 3 is Directly connected to one floor panel 1',
By connecting the side air outlet 26 and the other floor panel 1' via the auxiliary duct 38, it is possible to easily connect the three parts 3, 1', 1' without requiring a conventional branch pipe. Therefore, it is possible to improve the installation workability. In this case, hot air is blown out almost equally from both outlets 25, 26 of the hot air fan 3, so that uniform and effective hot air heating can be performed over the entire surface of the floor panels 1', 1'. I can do it.

In the above embodiment, a series of floor panels 1 is constructed by connecting a plurality of floor panel units 2, 2, . . .
Although the description has been made regarding a warm air floor heating system that constitutes a single floor panel, the present invention can of course be similarly applied to a hot air floor heating system that uses a normal single floor panel. Further, although an oil burner was used as the burner 9 in the above embodiment, the burner 9 of the present invention
It goes without saying that the burner is not limited to this, and for example, a gas burner may be used. Furthermore, the partition body 23 does not have to be box-shaped; for example, it may be hemispherical.

As explained above, according to the present invention, it is possible to send hot air from the front outlet, the side outlet, or both outlets of the hot air fan, and depending on the installation location, Hot air can be supplied by connecting either the outlet or the side outlet directly to the floor panel, and warm air can be supplied to two floor panels at the same time without the need for a diverter pipe, providing wide-area floor heating. Therefore, the installation work can be greatly simplified and the safety during use can be improved.
