Abstract

PURPOSE:To make even an indoor temperature distribution and minimize passing resistance of hot air and reduce noise or upgrade heating effect by slanting greatly a rear side of a non-discharge part of a conventional louver unit to blow out hot air against a vertical projection face of a device main body. CONSTITUTION:A heat generated in a burner unit 12 in a device main body 11 is transferred into a combustion furnace, thereby heating indoor air introduced from a convection fan 14. The heated hot air is blown off outdoors from a louver unit 15. In this case, a rear surface 15a in a conventionally non- discharge area in the louver unit 15 is largely slanted to a vertical projection plane of the device main body 11. For example, the rear surface 15a is designed so that it may lead from one end of the louver unit 15 in an outlet of an air supply line to a front end face on a tank guide side of a combustion frame 18 by way of a front ridge on a center side of a tank guide 17. This construction makes it possible to enlarge a discharge angle of hot air on both sides and equalize an indoor temperature distribution and at the same time to enlarge a discharge area of the louver unit, thereby reducing a passing resistance of hot air.

暖房状態になる。However, as shown in FIGS. 7 and 8, the louver portion 5 provided on the front surface of the apparatus body 1 is not
About 1/2 to 1/3 of the area of the louver portion 5 is a dummy (shown by the hatched portion 8 in FIG. 7) because of the space provided inside for the cartridge tank 6a. Therefore, the warm air is discharged from only about 1/2 to 2/3 of the area of the louver part 5, and the temperature distribution on the left and right is as shown in FIG. 9, which is an ideal heating to uniformly warm the room. It is far from heating.

Further, when the air guide plate is provided in the louver portion, there is a problem in that the discharge of warm air is hindered and the overall air volume is reduced, which in turn causes the temperature distribution in the room to deteriorate.

拡がった温度分布の暖房状態が得られる。In the above structure, the louver portion 15 has six louvers 15b (see FIG. 1) vertically positioned, and the tank guide 17 has a tilted back surface 15a on the front surface thereof. The mixing of the room air taken in by the convection blower 14 and the heat guided upward in the combustion furnace 13 in the air passage 16 does not mean that the room air and the heat are uniformly mixed. In the louver portion 15, since the indoor air passes above the combustion furnace 13 and is mixed with the indoor air having the same rotation direction as the convection blower 14,
When viewed from the front of the apparatus main body 11, the right side has a relatively high temperature and the left side has a low temperature distribution. (When the convection blower 14 is rotating to the right when viewed from the front of the device main body 11) In the warm air heating device configured as described above, the fuel supplied to the main device 11 becomes combustion air inside the burner 12. The mixed and combusted on the upper surface of the burner 12, the heat generated by the combustion of the burner 12 is guided to the upper surface in the combustion furnace 13, and the heat guided upward in the combustion furnace 13 and the convection blower 14 The taken-in room air is mixed in the blower path 16 and is heated as a warm air by inclining from the right side of the louver portion 15 and being relatively straightly discharged from the left side and the center side. Therefore, as shown in FIG. 3 of the temperature distribution in front of the main body of the apparatus, a heating state having a temperature distribution in which the lateral spread is wider than that of the conventional case can be obtained.

As shown in FIG. 5, the rear surface 15a of the louver portion 15 may be curved instead of being linear. Also, as shown in FIG. 5, the inclination of the rear surface 15a of the louver 15 may be changed depending on the amount of heat generated by the apparatus body 11 and the rotation speed of the fan. The angle may be changed by the motor 19, and the present invention is not limited to the above embodiment.
