Abstract

PURPOSE:To warm surrounding atmosphere fed into a room with discharged hot air by a method wherein an outer cylinder enclosing a flue with a desired clearance thereagainst and a blower for forcedly blowing the surrounding atmosphere into the clearance are provided, the clearance is closed at a side spaced apart from a combustion chamber, opened at a side near the closed end, the surrounding atmosphere is fed from the closed side and then discharged from the opening into the room. CONSTITUTION:An outer cylinder 3 is arranged with a desired clearance 4 against a flue 2 outside the flue, the clearance 4 is closed near an upper end part of the clearance 4, i.e. a part where the flue 2 is open to the surrounding atmosphere and then the surrounding atmosphere is forcedly fed into the clearance 4 with a blower 7. The surrounding atmosphere fed into the clearance 4 is fed toward a stove 1 through the clearance 4, heated by heated air discharged from the flue 2 and then supplied into a room. In case that the air is discharged into the room, an outer cabinet 8 is arranged so as to cover a combustion chamber 1 with a desired clearance 9 being left thereagainst. The air transferred in the clearance 4 is sent into the clearance 9 between the combustion chamber 1 and the outer cabinet 8 and sent to a room, resulting in that a further efficient heating of the surrounding atmosphere can be made and heated air can be sent into the room.

Description

TECHNICAL FIELD The present invention relates to a fireplace, and more particularly to a fireplace that can effectively utilize warm air exhausted through a chimney to condition the air in a room.

PRIOR TECHNOLOGY In modern times, electric heating and cooling systems have become widespread, and fireplaces are rarely used.However, recently the taste of fireplaces has been reconsidered, and houses and villas equipped with fireplaces have become quietly popular. There is. However, in the case of a fireplace, warm air escapes to the outside through the chimney, so the thermal efficiency is very poor.As a result, in many cases, the fireplace only serves to create an atmosphere, and in reality, electric heating and cooling equipment is not used. Often used.

Purpose The present invention was made in view of the above-mentioned circumstances.
In particular, the purpose of this invention is to provide a fireplace that effectively utilizes the warm air exhausted to warm outside air (cold air) introduced indoors.

Configuration FIG. 1 is a configuration diagram for explaining one embodiment of the fireplace according to the present invention. In the figure, 1 is a combustion chamber, 2 is a chimney, and as is well known, a conventional fireplace has a combustion chamber 1. The warm air burned inside the
At the same time as heating the room, a part of the heat is exhausted to the outside through the chimney 2, but the amount of heat exhausted through the chimney is large and the thermal efficiency is not very good. In addition, indoor air is generally not controlled, and there is a risk of oxygen deficiency in houses that use closed fittings, such as modern sash fittings.

The present invention has been made in order to solve the problems of the prior art as described in ``U'', and as shown in the figure, an outer cylinder 3 is provided on the outside of the chimney 2 with a predetermined gap 4 from the chimney 2. The gap is closed at the upper end of the gap 4, that is, in the vicinity where the chimney 2 communicates with the outside, and outside air is forcibly introduced into the gap 4 by the blower 7. The gap 4 is closed at the upper end, in other words, in the vicinity where the chimney 2 leads to the outside, by a partition plate 5, and the outside air sent in by the blower 7 as described above is forced through the gap 4 toward the fireplace. Blow air to. The outside air introduced into the gap 4 in this way is sent toward the fireplace 1 through the gap 4, but during that time it is warmed by the warm air discharged from the chimney 2, and the warmed air flows into the room. Supplied. When the air sent through the gap 4 is released into the room, a hole may be made below the outside 3 and the air is released from the hole, but as shown in the figure, the combustion chamber 1 can be An outer casing 8 is provided so as to cover the gap 9, and the air transmitted through the gap 4 as described above is sent into the gap between the combustion chamber 1 and the outer casing 8 and passed through the gap 9. If you send the outside air into the room later, you can more effectively warm the outside air and send it into the room.

In the present invention, as described above, the exhaust air from the fireplace is effectively used to warm the outside air and supply it into the room. If a partition plate 6 is provided and the outside air sent in from the blower 7 is sent along the spiral partition plate 6, the air passage becomes long, and the warm air discharged through the chimney 2 and the air passing through the gap 4 are elongated. Heat exchange is performed more effectively with the cold air supplied by the air.

Although the example above has been described in which intake air is passed through the gap between the chimney and the outer cylinder, the pipe is spirally wound directly around the chimney, outside air is forcibly fed from the upper end, and the lower end is opened. It is also possible to supply more air into the room.

Effects As is clear from the above explanation, according to the present invention, it is possible to effectively utilize exhaust gas to warm and supply outside air.
At the same time, it is possible to provide a fireplace with ventilation. Furthermore, since the air supplied from outside is supplied to the lower part of the room, the feet are warmer and the temperature distribution in the room is improved.
