Description

[Detailed explanation of the invention] Industrial application field This invention absorbs solar heat or takes in natural ventilation through the roof, walls, under the floor, etc., and controls the flow of air into and out of the building and the flow of air within the building. In a housing system that controls the temperature and humidity of a building (hereinafter referred to as "air cycle housing" (registered trademark)), it relates to underfloor ventilation holes that are installed to control the flow of air into and out of the floor of the building. It is.

Conventional technology and problems In air cycle houses, in summer, the valve of the underfloor ventilation opening on the windward side opens due to positive pressure from the wind from the windward side, and the valve of the underfloor ventilation opening on the leeward side opens due to negative pressure on the leeward side. The air that flows into the building through the windward ventilation opening flows through the building, ascends, and is released into the underfloor space, inner wall cavity, and shed space, thereby providing ventilation within the building (Figures 7 and 8). reference).

In winter, underfloor vent valves must be fixed closed to prevent cold outside air from entering the building.

In this way, the underfloor ventilation valves (check valves) used in air-cycle homes are opened by positive pressure from normal wind and closed by negative pressure, so they have extremely smooth movement. There must be.

The valves for the underfloor ventilation holes in conventional air cycle homes had a structure in which they were suspended from the top of the valve, which made them difficult to open and close if they were heavy, so the valves were made of thin plastic film or the like.
However, even though such materials are light and have good movement, they have problems such as low strength, lack of weather resistance, and early deterioration.

The present invention eliminates these problems and has a check valve that opens and closes quickly even though the valve is made of a material with sufficient strength and weather resistance and is heavier than conventional ones. In addition, the valve is fixed in a closed position so that it can be easily operated, so that the air cycle house functions more efficiently.

Means for solving the problems In order to solve the above problems, the present invention
An underfloor ventilation opening that is installed on the outer wall under the floor to communicate the underfloor space of an air cycle house with the outside of the building has an opening on the front facing the outside of the building.
In addition, the back side facing the underfloor space has a size that covers the entire opening, and is divided into two valve bodies, left and right, at the center of the width of the opening, and both ends are closed by the air flow. Equipped with a check valve that opens and closes in the underfloor space, an opening/closing lever is provided in the center of the front, and an opening/closing bar connected to the same lever with a connecting shaft is provided in the center of the back.By turning the opening/closing lever, The present invention is characterized in that the state of the opening/closing bar changes between a state in which the check valve is fixedly closed and a state in which the above-described opening/closing operation is allowed.

A spring for constantly biasing the opening/closing bar in the front direction may be provided on the rear side portion of the connecting shaft that connects the opening/closing lever and the opening/closing bar.

Function This invention allows air to flow into the under-floor space from outside the building when the check valve is freely rotatable, that is, can be opened and closed, by rotating the opening/closing lever attached to the front face of the air cycle house. The outflow of air from the building to the outside of the building is suppressed. At this time, since the valve is not suspended from above but rotates around a vertical axis, the weight of the valve does not act in the direction of closing the valve, and therefore the positive pressure of the wind, Negative pressure allows the valve to rotate smoothly.

Therefore, since the material of the valve has increased strength, weather resistance, etc., even if a material having a somewhat large weight is used, there is no problem in the rotation of the valve, that is, opening and closing.

In addition, in this invention, by rotating the opening/closing lever, the opening/closing bar on the back of the device is rotated, and the position where the bar suppresses the check valve is changed, so that the check valve can be adjusted depending on the season. It can be kept closed and fixed, stopping airflow into and out of the building.

Heat is discharged from the building by air flowing in and out as the valve opens and closes, and when the valve closes, the release of warm air is blocked, and the air stagnant inside the building has low thermal conductivity and is insulated. This property maintains the temperature inside the room.

Thus, according to the present invention, the temperature can be adjusted by controlling the flow of air within the building in an air cycle house.

Furthermore, the present invention can promote air flow within the building, thereby reducing humidity within the building.

Embodiments Hereinafter, the present invention will be described in detail based on illustrated embodiments.

1 to 4 show an underfloor ventilation opening according to an embodiment of the present invention.

In FIG. 1 showing the front view of this ventilation port, reference numeral 1 in the figure indicates a frame surrounding the ventilation port, 2 indicates an opening of the ventilation port surrounded by this frame 1; A large number of vertical grids 3 are provided at predetermined intervals,
At the center in the width direction, there is a central pillar 5 to which an opening/closing lever 4 is attached.

In FIG. 2 showing the rear view, reference numeral 6 denotes a check valve formed in a size that covers the opening 2 as a whole, and has two check valves on the left and right at the center of the back width direction of the middle pillar 5.
It is divided into two valve bodies 6a and 6b. Each of the valve bodies 6a and 6b has a shaft 7 such as a pin provided at the top and bottom of the inner end thereof, which is pivotally supported by a mounting portion 8 that projects upward and downward from the center column 5, and as the inner end rotates, the outer side The end opens and closes at an angle of, for example, 45 degrees toward the underfloor space.

Reference numeral 10 denotes a connecting shaft (see FIG. 5) extending from the inner surface of the opening/closing lever 4 through the central pillar 5, and an elongated opening/closing bar 11 is fixed to the tip of this connecting shaft 10. The opening/closing bar 11 rotates integrally with the opening/closing lever 4, and when positioned vertically along the back surface of the middle column 5, allows the above-mentioned opening/closing operations of both the valve bodies 6a, 6b. When the valve bodies 6a and 6b are in the position where they intersect with each other, hold the back surfaces of both the valve bodies 6a and 6b and
6b is made impossible to open and close.

In addition, the symbols 12 and 13 in the figure are reinforcing ribs provided on the back surface of the check valve 6, and the semicircular reinforcing ribs 12 provided on the inner end of each valve body 6a, 6b are for opening and closing as described above. It serves as a guide when the bar 11 is rotated.

Reference numeral 14 denotes a tension spring wound around the rear side portion of the connecting shaft 10, which biases the opening/closing bar 11 toward the opening 2 side, and when the valve bodies 6a and 6b are fixed closed, the valve 6 and the frame 1 Stabilizes the close contact with.

The usage status of this underfloor ventilation opening will be explained with reference to FIGS. 5 to 8. FIG.
The figure is a conceptual configuration diagram showing the air flow throughout the building when the present invention is in use in an air cycle house.

In the figure, the air that entered from the windward side (positive pressure) on the right side by pushing open the check valve 6 of the underfloor ventilation port A is
(See Figure 6) It rises from the underfloor space 15 through the inner wall cavity 16 with no ventilation resistance, flows into the shed space 17, and flows into the non-windward side (negative pressure. Sides other than the windward side have negative pressure). It is released outside the building from the shed ventilation opening 18. At this time, the underfloor ventilation opening on the leeward side (negative pressure)
The check valve 6' at A' is pulled closed by negative pressure, and no air is discharged from here to the outside of the building.

In this way, the building is ventilated, and in summer, the hot air and humidity inside the building are exhausted to the outside of the building. In winter, etc., by operating the opening/closing lever 4 and pressing the valve bodies 6a, 6b in the closed state with the opening/closing bar 11, the valves 6, 6' of the underfloor ventilation holes A, A' remain closed. This prevents cold outside air from blowing into the building, prevents warm air from escaping inside the building, and, together with the insulation of the stagnant air, keeps the inside of the building warm.

Of course, depending on the time of the day, for example, during the day, ventilation is performed and moisture is released, and at night, ventilation is turned off.
It can also be used to retain heat.

Effects of the invention As explained above, the invention allows air cycle houses to stop the air flowing in and out through the ventilation openings under the main floor by operating the opening/closing lever.
Alternatively, the air flow inside the building can be controlled by smoothly allowing air to flow into the building from outside the building and preventing it from entering the building. Depending on the season of the year (or the time of day, etc.), in winter, etc., the room temperature is reduced by suppressing the release of warm air inside the building and using the insulation properties of the air stagnant inside the building. In the summer, cool air is brought in from outside the building and hot air is expelled from inside the building, allowing the temperature inside the building to be controlled in an energy-saving way that saves energy from artificial heating and cooling. It is possible to create a natural and comfortable living environment.

Furthermore, since the present invention promotes the flow of air within the building, the humidity within the building can be controlled, preventing dew condensation under floors and behind walls, and preventing the building from decaying.
