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 and adjusts the temperature and humidity of a building (hereinafter referred to as "air cycle housing" (registered trademark)), it relates to a ventilation opening for a shed that is installed to control the flow of air in and out of the shed space of a building. It is something.

Conventional Technology and Problems Conventional ventilation holes for sheds only allow air to flow from the windward side to the leeward side within the shed space, and the inside of the building is not sufficiently ventilated. Another problem was that during strong winds and rain, rain would blow in through the ventilation holes on the windward side of the shed.

However, in air cycle homes, in summer,
Positive pressure from the wind from the windward side opens the valve of the underfloor ventilation opening on the windward side (the valves of the underfloor ventilation openings on the side that are not upwind, including those on the leeward side, are closed by negative pressure), and the air enters the building from the windward side ventilation opening. The incoming air flows and rises inside the building through the underfloor space and the inner wall cavity into the shed space, and the negative pressure on the non-windward side opens the valve of the shed ventilation opening on the non-windward side (windward side shed ventilation (The valve is closed by positive pressure from the wind to prevent rain from blowing in.) Air is released from inside the building, and the entire building is ventilated (see Figures 7 and 8).

In winter, the valves of both the shed vent and the underfloor vent are fixed closed to prevent warm air from leaking out of the building and preventing cold outside air from entering the building.

In this way, the shed ventilation valves (check valves) used in air cycle houses open with negative pressure from normal wind and close with positive pressure, so they have extremely smooth movement. There must be.

Conventional air cycle housing shed ventilation valves had a structure in which they were suspended from the top of the valve, so if the valve was heavy, it would be difficult to open and close, so the valve was 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 Problem In the shed ventilation opening that is attached to the outside wall of the shed to communicate the shed space of an air cycle house with the outside of the building, an opening is provided on the back facing the shed space, and On the front facing, the entire valve body has a size that covers the opening, is divided into two left and right valve bodies at the widthwise center of the opening, and both ends are
The above-mentioned opening is provided with a check valve that opens and closes toward the outside of the building by negative pressure generated outside the building based on the air pressure difference between the shed space and the outside of the building, and the opening faces the peripheral edge of the check valve. Cushion rubber is attached to the four circumferences or a part of the part to make the air pressure difference noticeable, and the opening/closing bar is attached to the center of the front, and the opening/closing lever is connected to the opening/closing bar by a connecting shaft in the center of the back. are respectively provided, and by turning the opening/closing lever, the state of the opening/closing bar changes between a state in which the check valve is fixed closed and a state in which the opening/closing operation described above is freely performed. Has characteristics.

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

Function This invention allows air to flow out from the shed space to the outside of 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 back of the air cycle house. The inflow of air into the shed space 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 air Negative pressure allows the valve to rotate smoothly. In addition, the present invention further improves the airtightness of the shed space by attaching cushion rubber to the four circumferences of the opening or a part thereof, thereby significantly reducing the air pressure difference between the shed space and the outside of the building. This increases the effect of negative pressure on the rotation of the valve.

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, the opening/closing bar on the front part can be rotated by rotating the opening/closing lever.
By changing the position of the bar that suppresses the check valve, it is possible to keep the check valve closed and fixed depending on the season, thereby stopping airflow from entering and exiting the shed space (inside the building) to the outside of the building. can.

Heat is discharged from the building by air flowing in and out as the valves open and close, and warm air is prevented from leaking when the valves are closed, 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.

making it impossible to open and close the door.

In addition, the symbols 12 and 13 in the figure are reinforcing ribs provided on the front side 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.

FIG. 3 shows a side view of the main ventilation port, and FIG. 4 shows a top view of the same. Reference numerals 15 are holes in the frame around the lattice 3 in order to pass the wire 14 for remotely controlling the opening/closing lever 4. It is a hole that has been drilled.

Reference numeral 16 denotes a tension spring wound around the front side portion of the connecting shaft 10, which biases the opening/closing bar 11 toward the opening 2, and when the valve bodies 6a and 6b are fixed closed, the valve 6 and the plate Stabilizes the close contact with 1.

Reference numeral 17 denotes a cushion rubber attached to the four circumferences or a part of the opening 2 of the main ventilation port, which together with the tension spring 16 improves the airtightness of the valve 6 in the closed state, and when the valve 6 is opened and closed. , it is possible to prevent the generation of noise by preventing it from directly hitting the plate 1.

The state of use of the main cabin ventilation opening will be explained with reference to FIGS. 5 to 8. Fig. 7 is a cross-sectional view of a shed section of a building to which the present invention is installed, and Fig. 8 is a conceptual configuration diagram showing the air flow throughout the building when the present invention is used in an air cycle house. .

Regarding this invention, a practical application filed by the applicant in 1983
The underfloor ventilation port No. 146276 (Utility Model Application No. 60-54033) is installed in the outside wall under the floor so that the check valve allows air to flow into the building from outside the building, but not vice versa. In contrast, the present invention is installed on the outside wall of the shed in exactly the opposite way, allowing air to flow from inside the building to outside the building, but not vice versa. control.

However, the above-mentioned Utility Application No. 146276 (1983)
54033), the valve opens due to positive air pressure, but in the present invention, the valve opens due to negative air pressure, and the physical principle used is different. In the present invention, in general, compared to positive pressure,
The cushion rubber improves airtightness in order to create a significant negative pressure that requires less force to open the valve.

If the right side is the windward side, the air that enters from the windward side (positive pressure) by pushing open the check valve of the underfloor ventilation port B (see Figure 6) will flow from the underfloor space 18 to the ventilation It rises through the inner wall cavity 19 etc. where there is no resistance, flows into the shed space 20, and exits the building through the shed ventilation opening A' on the non-windward side (negative pressure. The side other than the windward side has negative pressure). released. At this time, air is also discharged outside the building due to negative pressure at the shed ventilation opening A, which is not shown in this figure, on the opposite side of the building from the shed ventilation opening A'. However, as shown in Figure 7, if the shed ventilation opening A is on the windward side (positive pressure), the check valve of the ventilation opening will be closed by the positive pressure, and air will not be released 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 shed ventilation openings A, A' remain closed. This prevents hot air from leaking inside the building and at the same time prevents cold outside air from entering the building, and in combination with the insulation of the stagnant air, keeps the room 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 enables air cycle houses to allow air to flow out from the shed space (inside the building) to the outside of the building by operating the opening/closing lever, or to prevent the reverse from occurring. Smoothly perform the operation of stopping the passing air in and out,
Control airflow within buildings. In order to drain the air from this shed space to the outside of the building, we utilize the effect of negative pressure generated outside the building based on the pressure difference between the air inside and outside the building. The cushioned rubber seals the cabin space tightly and creates a significant air pressure difference.The negative pressure outside the building created by this pressure difference makes it easier to control the valve rotation and thus the airflow. It becomes smooth.

Depending on the season of the year (or the time of day, etc.), in winter, etc., the room temperature is reduced by suppressing the leakage of warm air inside the building and utilizing the insulation properties of the air stagnant inside the building. In summer, the temperature inside the building can be controlled by bringing in cool air from outside the building and discharging the hot air inside the building.
It saves energy by saving energy from artificial heating and cooling, creating 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.

In addition, according to the present invention, since the blowing of wind from outside the building into the shed space is suppressed, the blowing of rain is prevented. Since the cushion rubber improves the airtightness of the building, the blowing of wind and rain can be further suppressed. This cushion rubber also has
It also prevents the generation of noise caused by the rotation of the check valve.
