Description

DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating system using hot air.
It is about. [0002] 2. Description of the Related Art FIG. 3 shows a conventional floor heating device of this kind.
Heat insulating material 10 on the bottom surface and the peripheral wall surface of the underfloor space A,
11 and hot water coil supplied with hot water from the water heater 15
Hot air generator 6 composed of a fan 6b and a fan 6b.
Then, warm air is circulated through the underfloor space A to warm the floor material 1.
It is like that. However, this method uses the flow rate of hot air
Heat transfer efficiency from warm air to flooring 3 is low
In general, in floor heating, room temperature
Separate from the comfortable floor temperature
With the spread of aluminum brushes, airtightness has improved and wall
In buildings with improved thermal insulation such as ceilings and ceilings,
Room temperature rises too high when trying to maintain temperature
Floor does not reach comfortable temperature when trying to maintain comfort
There was a problem. [0003] SUMMARY OF THE INVENTION The present invention has the above-mentioned problems.
In view of the above, floor heating equipment with low equipment cost and high thermal efficiency
The primary purpose is to provide a comfortable room,
The necessary and sufficient amount of heat to keep
Providing this kind of floor heating system that can be achieved
The second purpose is to do so. [0004] According to the first aspect of the present invention,
The floor heating device, as shown in FIG.
Circulates and heats flooring 1Floor heating systemsmell
Then, a joist 3 is erected on the sculpture 2, and the floor material
1 and at the center of the roomMultipleBig deal
2 are connected to each other by a plate 4 having an appropriate width.
4 and above flooring 1Forming small open space B around
And the outlet of the warm air duct 5 opened at the bottom of the small space B
By attaching the shielding plate 8 to the lower surface of the joist 3 above the 9
Provided,Hot air generator 6 through hot air duct 5 (see FIG. 2)
From the opening 7 around the small space B
So that the hot air returns to the hot air generator 6 through the underfloor space A
It was done. [0005] According to the above construction, the air supplied from the hot air generator 6 is provided.
The warm air to be blown first is a small air created between the floor material 1 and the plate material 4.
Enter the space B, and go out to the underfloor space A through the opening 7 therearound.
Until it goes out of the small space B from the opening 7,
The upper surface of the small space B without being mixed with the outside air whose degree has decreased
The flooring 1 of the room and thereby the floor in the center of the room
Can give the human body a comfortable temperature higher than room temperature.
And after coming out of the opening 7, the specific gravity at high temperature
Air spreads along the lower surface of flooring 1
As a result, the efficiency of heat transfer to the floor material 1 has been improved compared to the past,
Lugi can be realized.Furthermore,On the bottom of small space B
Open hot air duct 5Outlet 9AboveShield plate 8To
EstablishmentBecauseHot airOutlet 9(See Fig. 2)
To prevent overheating locally on the floor material 1
be able to. [0006] 1 shows an embodiment of a floor heating apparatus according to the present invention.
As shown, joists 3 are erected on the large
The floor material 3 is stretched over the joists 3 of the floor to form a floor.
The central part of the room, for example, the area of 1 to 2 tatami mats in the center between 6 tatami mats
In the area, between the two big pulls (at 910 mm intervals)
Veneer plywood with a width of 5 joists (455mm intervals)
One plate 4 consisting of nails on the lower side of both sides
It is pierced in this plate material 4
Hot airOutlet 9The upper end of the hot air duct 5 is connected to
You. The other end of the hot air duct 5 is connected to the hot air duct 5 shown in FIG.
Connected to the discharge port of the wind generator 6 and from the small space B to the surroundings
The air expelled to the back of the hot air generator 6 from the underfloor space A
It is sucked into the suction port on the surface. Note that in FIG.
And 11 are provided on the peripheral side wall and the bottom surface of the underfloor space A.Foaming tree
FatIn the summer, the underfloor vent 12 is
An insulated airtight door 13 which is opened and closed in winter is provided.
ing. Reference numeral 14 denotes a heat insulating wall panel. According to the present invention, as described above, the plate 4 and the floor 1
To form a small space B whose periphery is open
First, the warm air supplied from the warm air generator 6
B and the limited floor surface of the upper surface of the small space B
After warming, it goes out of the small space B to the underfloor space A,
It is designed to return to the wind generator 6,
Room temperature at an average temperature lower than the floor temperature in the center of the room
Heating, so that when people sit or sit,
It is designed to give a high comfortable temperature. FIG. 2 shows another embodiment of the present invention.
In the embodiment shown in FIG. 1, the plate 4 is taken between two large pulls.
It was attached, but it was attached to three
The area where the floor in the center of the room becomes hot is 2 tatami mats.
The hot air duct 5 is branched into two,
Place outlet 9 in two adjacent spaces between the three drawers
Each is provided. In addition, the temperature opening at the bottom of the small space B
Wind duct 5Outlet 9Above, warm air blown out
Prevents local overheating by directly hitting the lower surface of flooring 1
Made of gypsum board of suitable size forShield plate 8
By screwing both sides to the underside of joist 3
It is attached. [0009] According to the present invention, as described above, the generation of hot air
The warm air supplied from the machine 6 is first supplied between the floor material 1 and the plate material 4.
It is sent into the formed small space B,
Heats flooring material 1 on the upper surface of small space B without mixing with air
And the floor in the center of the room
Can provide a comfortable temperature to the human body.
Like this type of floor heating system, the room temperature is controlled to the optimum temperature.
When the floor is too cold or when the floor is
Room temperature will not be too high when controlled
After the warm air comes out of the opening 7
Also, high-temperature, light-weight air flows along the lower surface of the flooring 1
Heat transfer efficiency to the floor material 1 as compared to the past
And energy saving can be realized.
There are points.
