DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a house at the time of snowfall, and shows a covering tube 2 that forms and covers a space 7 from below the floor of the combustion type heater 3 provided in the room on the outer periphery of a chimney 1 standing in the room. The upper end of the coating tube 2 is provided open near the ceiling.

As shown in FIG. 2, the inner peripheral surface of the coating cylinder 2 is formed as a spiral flow path 8, and the air in the room entering through an open port 9 descends while being heated while being in contact with the heated chimney 1. In addition, open to the outside and then into the basement, so that the air inside the pipe is slightly warmed in the ground, a relatively long underside U-shaped pipe is used in the ground, and the pipe extends from the outdoors to the ground and goes under the floor. The obtained intake pipe 12 is provided. In this way, the intake pipe 12 for taking in outside air communicates with the inner space 7 of the coating cylinder under the floor, and the fan 4 is provided in the vicinity of the area where the communication and the joining take place.
With this fan 4, cold outside air flowing through the intake pipe 12 from the outdoor opening 10 and warm air flowing through the spiral flow path 8 can be sucked.

A mixture of high-temperature air of 50 to 70 ° C., which is taken in from the room and heated by the heat of the chimney, and low-temperature air of 0 to 15 ° C., which is taken in from outside, has a temperature of 25 ° C.
The airflow is at an appropriate temperature before and after, and the air is well ventilated and oxygen-rich. The ventilated air of the appropriate temperature is blown out by the fan 4 and passes through the air passage 17.
The air is forcibly discharged into the room through the through-hole 11 on the floor surface communicating with the air flow path 17, and the room is mixed with fresh outside air and warmed by the warmed air. Further, by providing the outlet of the air flow path 17 to extend to the wall as shown in FIG. 3, warm air can be blown out to the wall air circulation part 5a, and the wall of the room is heated. Since the wall air circulation portion 5a is provided inside the heat insulating material 22, it is not cooled by outdoor cool air. Wall air circulation unit 5
“a” is provided on at least one or more of the four wall portions, but is preferably provided on at least the north side where dew condensation often occurs. Further, a valve 21 is provided in each of the plurality of through-holes 11 on the floor surface, and at least one of the through-holes 11 is opened to release warm air.
The number of holes to be opened can be arbitrarily selected by opening and closing the valve 21 of the hole. In addition, intake pipe 1
2 is preferably buried in the ground, but is not limited to burying.

As shown in FIG. 1, the warm air passes through the air flow path 17 and enters the wall air flow section 5a and rises. Although the raised air reaches the roof, for example, a damper 14a is provided at a portion where the skeleton of the wall surface and the skeleton of the roof are in contact with each other as shown in an enlarged sectional view of FIG. When the damper 14a is set to the position 14a shown by a solid line on a day when there is no snowfall,
a passes through the path indicated by the arrow 18, the air inlet 20 to the under roof is closed, and the under-air
a, and does not enter the under-roof air circulation section 6b, but enters the under-air air circulation section 5b. This prevents the warmed air from being cooled down under the roof and keeps the room warm even from above the ceiling.

As shown in FIG. 4, when the damper 14a is moved to a position 14b indicated by a dotted line on a certain day of snowfall, the warm air passing through the air circulating portion 5a of the wall portion travels along a path indicated by an arrow 19 indicated by a dotted line. , And enters the under-roof air circulation section 6a and the eaves-under-roof air circulation section 6b in addition to the under-air air circulation section 5b. In this way, the warm air is transferred to the under-roof air circulation unit 6.
a and the eaves section under the roof air circulation section 6b, by slightly raising the temperature under the roof, it is easy to melt the snow that has fallen on the roof, and the amount of snow on the roof can be slightly reduced. In particular, the warm air entering the eaves under roof air circulation section 6b stays there, so the eaves roof is heated,
Snow on the roof of the eaves becomes easier to fall. This makes it easier for the snow on the upper roof to fall in a chain, thus reducing the task of removing snow.

An example of the damper 14a has a structure as shown in FIG. 4. A hinge 15 is provided at a lower portion of the damper 14a, and a string attached to the damper 14a is connected to an outdoor string 13a via a pulley 16a. Indoor string 1 via 16b
By providing two of 3b, it is possible to freely open and close the air inlet 20 entering the under-roof air circulation section 6a and the eaves-under-roof air circulation section 6b, and the degree of opening and closing can be adjusted. When the outdoor string 13a is pulled downward, the damper 14a inclines to the left to the position of 14b, and the warm air is released from the airflow section 5 above the ceiling.
b, flows into the under-roof air circulation section 6a and the eaves-under-roof air circulation section 6b. When the indoor string 13b is pulled downward, the damper 14b is inclined rightward to the position of 14a, and the warm air flows only into the airflow section 5b above the ceiling. The damper 14a may be divided along the roof girder direction in consideration of operability, and the length of the damper 14a is not limited.

[0013]

According to the indoor air conditioner of the present invention, the indoor air flows into the covering cylinder that covers the chimney standing up in the room, and the outside air and the fan that have passed through the intake pipe from the outdoor opening allow the air to flow. Mixing, ventilating and warm fresh air can be released from the air passage under the floor to the air circulation section in the room and on the wall. In addition, there is no need to open the windows one by one to ventilate, and the room in which the combustion heating is performed is always rich in oxygen, so that a warm environment can be maintained.

[0014] Further, if the heating is performed all the time, the air in the ceiling is abnormally heated, but the fan under the floor is turned to suck the air in the ceiling into the coating cylinder and guide the air under the floor. Since it can be mixed with fresh outside air and released into the room, abnormal heating of the ceiling can be prevented, and the entire room can be warmed from the floor. The temperature difference between the first floor and the second floor can be eliminated, and a comfortable living space can be maintained. In addition, fresh and cold air taken in from outside is mixed with air that is effectively heated by the heat of the chimney, so that the heat energy of the heater can be reused, requiring large installation and maintenance costs. No, it can be ventilated and heated.

Further, by providing an air circulation portion on the wall portion and allowing warm air to pass through, the temperature of the room and the air circulation portion become substantially the same temperature, preventing the accumulation of air and warming the wall surface, and condensing the wall. And the back of the wall and the skeleton can be prevented from decay.

Furthermore, by passing warm air through the air circulation section under the roof, the amount of snow on the roof, particularly on the roof of the eaves, can be reduced in an area where there is much snowfall in winter, and the snow removal work can be reduced. .
