Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a hot air heater that improves comfort in an indoor environment.

[Prior art]

Conventionally, this type of apparatus has been shown in FIG. 1, as described in Japanese Patent Application Laid-Open No. 152,644/1983. In this figure, 1 is the housing of the floor-standing hot air heater, 2 is the suction port provided on the top surface of this housing 1, 3 is the blower installed inside the housing, and 4 is also inside the housing 1. A heat exchanger provided, 5 is a first outlet that blows out air that does not pass through the heat exchanger 4, 6 is a second outlet that blows out air that has passed through the heat exchanger provided at the bottom, 7 is the floor.

In the hot air heater configured as above, the suction port 2 is operated by the blower 3 and the heat exchanger 4.
A part of the indoor air that has been sucked in is directly transferred to the
The other air passes through the heat exchanger 4 and becomes high-temperature air, which is then blown into the room from the second outlet 6. Therefore, the indoor air blown from the first air outlet 5 suppresses the high temperature air blown from the second air outlet 6, allowing the high temperature air to reach a long distance along the floor surface. However, there were drawbacks such as a draft feeling due to the temperature difference between the room temperature air and the high temperature air, and an unpleasant draft feeling due to the influence of the airflow from the vicinity of both ends of the outlet.

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and includes a second outlet that blows out high-temperature air that has passed through a heating section such as a heat exchanger or a combustor toward the floor surface; Above the second air outlet, there is a first air outlet that blows out weakly warm air whose temperature is higher than the indoor air temperature and whose temperature is lower than the high temperature air, with a width narrower than that of the second air outlet. By blowing out this mildly warm air along the upper side of the high temperature air, the rise of the high temperature air is suppressed and the high temperature air reaches a long distance along the floor surface, and the airflow from both ends of the outlet is mainly controlled. To provide a warm air heater with improved comfort and less draft feeling caused by the influence.

[Embodiments of the invention]

The details of this invention will be explained below according to the illustrated embodiments. FIG. 2 is a sectional view of a floor-standing hot air heater showing an embodiment of the present invention, in which 1 is a housing, 2 is an inlet provided on the back of the housing 1, and 3 is a rear surface inside the housing. A blower 7 is installed on the floor, and these are similar to the conventional device shown in FIG. 8
is a second air outlet provided on the front surface of the housing 1,
Reference numeral 9 denotes a first air outlet provided above the second air outlet on the front surface of the casing 1, and both of these outlets are structured to blow out air obliquely downward. Reference numeral 10 denotes a partition plate made of a relatively good thermal conductor that separates the air flow to the second air outlet 8 and the air flow to the first air outlet 9; 11 indicates the partition plate 10 and the housing 1; The air duct 12 thus formed is also formed by the partition plate 10 and the housing 1.
A heating chamber 13 is formed in the lower part of the heating chamber 12, and 13 is a combustion section as a heating section that uses oil or gas as fuel, and 14 is a blower for combustion. Note that the air outlet width l ₁ of the first air outlet 9 is smaller than the air outlet width l ₂ of the second air outlet 8 as shown in FIG.
As shown in FIG. 3, the width is also smaller than the blowout width _l2 of the second blowout port 8.

In the floor-standing hot air heater configured as described above, when operation is started, gas or oil is combusted in the combustion section 13 by indoor air taken in by the combustion blower 14. Then, the heating chamber 12 is heated by the combustion in the combustion section 13. The air duct 11 is also heated through the partition plate 10 which is a good thermal conductor. A part of the indoor air sucked in through the suction port 2 provided on the back of the housing 1 is then transferred to the combustion section 1.
3, the air becomes high temperature and is blown out diagonally downward toward the floor 7 from the second outlet 8. Other room air passes through the ventilation duct 11 heated by the combustion section 13 through the partition plate 10 with relatively good heat conduction, becomes slightly warmed air, and is directed toward the floor 7 through the first air outlet 9. The rise of the high-temperature air blown out from the second outlet 8 is suppressed by the slightly warm, slightly warm air blown out from the first outlet 9, and the high-temperature air is blown away along the floor surface. and the first air outlet 9
As shown in FIG. 3, the width of the air passage of the ventilation duct 11 leading to the air duct 11 is smaller than the width of the second air outlet 8.
The draft feeling due to the warm air blown out is reduced, and the influence on the draft feeling due to the warm air from the vicinity of both ends of the second and first air outlets 8 and 9 is also small.

In addition, although the said Example demonstrated the case where the combustion part was arrange|positioned in the heating part, a heat exchanger may be used and the same effect as the said Example is produced.

In addition, although the partition plate 10 has been described as having relatively good heat conduction, it is made of a heat insulating material with openings in some parts so that the high temperature air from the heating chamber 12 is sucked into the ventilation duct 11. It may be.

〔Effect of the invention〕

As described above, according to the present invention, at the upper part of the second outlet which blows out high-temperature air toward the front and downward, there is a damper that is higher than the indoor air temperature and lower than the high-temperature air blown out from the second outlet. A first outlet that blows hot air forward and downward is also provided, and the width of the outlet is smaller than the width of the second outlet, so that the weakly warm air from the first outlet is Therefore, it is possible to suppress the rise of high-temperature air and allow the high-temperature air to reach a long distance along the floor surface, and the temperature difference between high-temperature air and low-temperature air is small. Since it is smaller than the width, it is possible to obtain a highly comfortable living environment with relatively little draft feeling.
