Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved ventilation system for an air cycle house.

[0002]

2. Description of the Related Art In an air cycle house, ventilation walls made of a heat insulating material are provided inside the outer wall of the building and under the roof, and natural ventilation is introduced into the ventilation layer formed between the outer wall and the ventilation wall. In addition, the temperature and humidity of the building are adjusted by allowing the air in the ventilation layer to absorb solar heat through the walls and the roof and controlling the flow / stop of the air flow by utilizing the pressure difference of the air generated in the ventilation layer. In this air cycle house, a ventilation device that allows air to flow in only one direction is attached to each of the roof portion and the wall portion of the building.

A ventilation device attached to a shed ventilation opening formed in the upper part of the wife is, for example, Japanese Utility Model Application No. 58-162505.
The structure shown in the issue is adopted. That is, this ventilation device has a frame body fitted in the ventilation port and a valve divided into left and right in the center in the width direction, and the valve is generated outside the building due to a pressure difference between the cabin space and the outside of the building. Upper and lower side ends near the center in the width direction are pivotally supported by the frame body so as to open toward the exterior of the building by negative pressure and close by positive pressure outside the building. An opening / closing cover is provided on the back surface of the valve, and the opening / closing cover is rotated to change between a state in which the valve is fixed in the closed state and a state in which the opening / closing state is allowed. ..

When the building blows with wind, the ventilator located on the positive pressure side closes the valve to prevent air from flowing into the cabin space, while the ventilator located on the negative pressure side opens the valve. The air in the hut space is let out to the outside of the building. In winter or the like, the opening / closing cover is rotated to a position where the valve is closed and the valve is fixed as it is.

However, the conventional ventilation device has the following problems. In order to open and close the valve by the slight pressure difference described above, it is necessary to have a structure that allows the pivot portion to move smoothly, which makes the structure complicated.

When a valve collides with a valve seat to make a noise when it is opened and closed and a sound is generated and it becomes necessary to replace the valve or repair the rotating part, the whole must be removed. .. In order to adjust the quality of the flowing air, it is necessary to adjust the opening and closing of the valve, but that control is difficult.

Since the valve has a structure that opens and closes in the horizontal direction, if it is attempted to mount it on the roof ridge in order to increase the efficiency of ventilation in an air cycle house, it is necessary to build a roof and then mount it on the wall of this roof. It has to be large, bulky, and expensive.

[0008]

SUMMARY OF THE INVENTION In view of the problems of the conventional ventilation device as described above, the present invention has a simple structure and does not generate noise, and the flow rate adjustment and repair can be performed reliably and easily. It is an object of the present invention to provide a ventilation device for an air cycle house that can be installed in a roof surface and can be directly attached to the roof surface close to the roof ridge.

[0009]

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention is directed to a ventilation port formed in a roof or an outer wall of an air cycle house, and is installed in an air cycle house. In an air-cycle residential ventilator that allows flow in only one direction, an air flow control body formed by bundling a number of small-diameter pipes of a specified length and inner diameter so that their outer periphery is in close contact with the ventilation port, and air flow. It is characterized by the fact that it is attached with a lid that can be opened and closed.

As for the positional relationship between the air flow control body and the lid body, any of them may be located outside the building along the direction of the air flow, and the air flow control body may be placed in a direction orthogonal to the opening / closing direction of the lid body. A structure may be adopted in which the lid and the air flow control body are entirely covered with a hood and the front end direction of the air flow control body of the hood is opened.

The airflow control body may be arranged so that the small-diameter pipe end portion on the outer side of the building is lowered.

A protective cover may be provided on the front surface of the air flow control body facing the outside of the building, and a drainage port may be provided on at least one of the lower front surface and the lower rear surface.

[0013]

When the lid is opened, the inside and outside of the building are in communication with each other through this ventilation device. When the outside facing the ventilator is in a positive pressure state due to the airflow, the airflow tries to enter the through-cylinder from the front of the airflow control body through the protective net with a relatively strong pressure. When such a strong air flow tries to flow in the small diameter pipe, a turbulent flow is generated in the pipe, which becomes a resistance against the flow of the air flow, and only a small amount of the air flow passes in comparison with the strength of the positive pressure. The resistance due to the occurrence of this turbulent flow increases as the length of the small diameter tube increases and as the inside diameter of the tube decreases.

On the other hand, when the outside of the building facing the ventilation device is in a negative pressure state, the air in the building receives a relatively weak force sucked to the outside of the building. As a result, the air in the building tries to flow through the ventilation tube and the small-diameter pipe of the air flow control body, but in this case, the flow in the pipe becomes a laminar flow, the flow resistance of the air flow is small, and the negative pressure An amount of airflow proportional to the strength of the airflow passes and is guided to the outside of the building.

Therefore, for example, considering the pressure condition of the wind around the building as shown in FIG. 8, the negative pressures applied to the three main ventilation devices A'are averaged for the positive pressure 3 applied to the main ventilation device A. 1
Then, for three exhaust air amount meters 3 from A ', A
The amount of inflowing air from can be set to be around 1.

Therefore, in the ventilator, for example, by the combination as shown in FIG. 8, the air in the building (shed space) as the entire roof surface can be discharged to the outside of the building.
Of course, air rises and flows into the hut space from the lower part of the building, the underfloor space, etc. to ventilate the building.

When it is not necessary to let the air in the building flow out to the outside depending on the season or the time of day, the lid may be closed.

[0018]

The present invention will be described in detail below with reference to the illustrated embodiments. 1 to 3 are an external perspective view, an exploded perspective view and a vertical sectional view of a ventilation device according to an embodiment of the present invention, respectively. This ventilation device is attached to a ventilation port formed in the ridge of the roof.

In the figure, reference numeral 1 is a rectangular mounting substrate made of a thin iron plate material, and a through cylinder 3 is fixed to an opening 2 formed at a predetermined position on the plate surface. The through-cylinder 3 includes a body portion 4 that is inserted into the opening 2 and a waterproof wall 5 that extends from the body portion 4 in the horizontal direction and then rises by a required length.

Reference numeral 6 is a lid that closes the upper portion of the body 4, and is a waterproof wall 5.
It is attached so that it can be opened and closed by being pivotally supported at one end on the inside. Reference numeral 7 denotes an operation lever for opening and closing the lid body 6, the upper end of which is pivotally supported by the back surface of the lid body 6, and the lower end of which extends downward through the body portion 4.

Reference numeral 8 denotes a hood that covers the upper surface of the mounting substrate 1,
The lower portion has a flange portion 8a that is screwed to the mounting substrate 1, and the main body portion 8 bulges upward from the flange portion 8a.
b is formed in a size that covers the surface of the mounting substrate 1 including the through cylinder 3 over a required area. Further, the main body portion 8b of the hood 8 has an open front surface in the opening / closing direction of the lid body 6, and a protective net 9 is attached to this front direction.

An airflow control body 10 is detachably attached to an inner space of the hood between the protective net 9 and the above-mentioned communicating cylinder 3. The air flow control body 10 is formed in a size having a cross-sectional area almost equal to the area of the protective net 9 by bundling a plurality of small diameter pipes 11 so that their outer peripheral surfaces are in close contact with each other, and the front end of the small diameter pipes 11 is formed. Is fixed to the side of the protective net 9 with the rear end of the small-diameter pipe 11 directed to the cylinder 3 side. The small diameter tube 11 is made of corrugated cardboard, plastic sheet, waterproof paper or the like in a tubular shape. The cross-sectional shape of the tube is not limited to the circular shape as in this embodiment, and may be a square shape, a hexagonal shape, or the like. The inner diameter and length of the pipe are due to the negative pressure weaker than the positive pressure because the inflow resistance becomes large and it is difficult to invade the strong air flow due to the positive pressure entering the pipe from the end face, and it flows out through the pipe. It is only necessary that the outflow resistance is small with respect to the air flow, and the condition that the outflow is easy is given.

The amount of air flowing between the through cylinder in the hood and the outside of the building is adjusted by the inner diameter r and the length L of the small-diameter pipe constituting the air flow control unit 10 (see FIGS. 4 and 5). As shown in FIG. 6, it is also possible to arrange a plurality of air flow control bodies 10 and 10 'in series at intervals in the axial direction of the small diameter tubes 11 and 11'.

In order to prevent rain from entering from the outside of the building, the airflow control body 10 may be arranged so that the front end of the small diameter pipe 11 is lowered.

Reference numerals 12 and 13 in the figure denote the air flow control body 1.
Upper and lower guide members for fixing 0 in the hood 8, 1
Reference numeral 4 denotes a drain port provided between the through cylinder 3 and the lower guide member 13. The drainage port 14 may be provided in front of the airflow control body 10 or in both of the front side and the rear side.

The ventilators A and A'having the above-mentioned structure are provided in the through cylinder 3
The body portion 4 is inserted into the opening 2 formed on the roof surface close to the ridge from above, and the hood portion 8 is fixed so as to project from the roof surface.

The use condition of the fixed ventilation devices A and A'will be described. First, FIG. 8 is an explanatory diagram showing the pressure situation of the air around the building when the wind blows. In the figure, when the surface on which the wind blows (upper surface in the figure) is viewed as the front of the building, the front has positive pressure, and the left and right sides and the back have negative pressure. Therefore, in the summer, etc., the ventilation device A in which the operation lever 7 is pushed up to open the lid body 6 and the inside of the hood and the cabin space are in communication with each other through the communicating cylinder 3 is located at a position where it receives the above positive pressure of wind. In the case of 1), air tries to flow in from the front surface of the hood 8. However, the air flow control body 10 has a small diameter pipe 11
Since a strong air flow due to positive pressure is unlikely to enter, it is unlikely to enter the hood 8 inside the air flow control body 10 due to the resistance of the thin diameter and the length.

On the other hand, the three ventilating devices A'located on the negative pressure side are subjected to a force for drawing air from the inside of the device body to the outside of the building (each negative pressure applied to A'is (Less than the positive pressure applied to), the warmed or moist air in the cabin space changes its direction in the hood 8 through the passing cylinder 3 by this force, and from the front end of the small-diameter pipe of the air flow control body 10 to the roof surface. Spill along. After all, by appropriately selecting the length and diameter of the small-diameter pipe, the outflow air amount can be easily set to about 2 to 6 times the inflow air amount by combining four airflow control bodies as shown in FIG. 8, for example. As a result, air is exhausted from the inside of the building (shed space) to the outside of the building as the entire roof surface. To the hut space, from the bottom of the building, the space under the floor,
Air rises, flows in, and the building is ventilated. And
Hot air and humidity inside the building are discharged.

In winter or the like, the operating lever 7 is lowered to close the lid 6 to prevent leakage of warm air inside the building and at the same time prevent cold outside air from entering the building. Of course, depending on the time of day, for example, ventilation can be performed during the day to discharge moisture, and ventilation can be stopped at night.

When the air tries to enter from the outside of the building, dust and dust in the air, insects and the like are trapped by the protective net 9 and do not enter the inside and block the small diameter pipe 11. In addition, the rainwater is decelerated by the protective net 9, and the small-diameter pipe 11 of the airflow control body 10 is used.
Since the diameter of the small-diameter pipe is small, the small-diameter pipe 11 does not penetrate from the outer end of the small-diameter pipe 11 into the through cylinder through the pipe line. Even if rainwater travels inside the small-diameter pipe 11 and enters the through-cylinder 3 side, the rainwater is guided to the outside of the hood through the drainage port 14. Moreover, since the upper portion of the through cylinder 3 is formed as the waterproof wall 5 protruding upward from the substrate 1, there is no fear that rainwater reaching the inner end of the small diameter pipe 11 will flow into the through cylinder. The airflow control body 10, which is attached so as to be inclined so that the front end of the small diameter pipe 11 is lowered, more effectively prevents rainwater from entering.

FIG. 9 shows an embodiment in which the present invention is applied to a ventilation device attached to a shed ventilation port. The ventilation device B is installed in the through cylinder 103 so that the lid body 106 and the airflow control body 110 having the above-described structure are aligned in the axial direction of the through cylinder 103. Through cylinder 103
Is inserted into the mounting opening formed on the top of the building's wife,
An airflow control body 110 is fixed in the end portion of the through-cylinder 103 on the outer side of the building so that the axis of the small-diameter pipe 111 coincides with the axial direction of the through-cylinder 103 and projects into the building of the through-cylinder 103. An openable and closable lid 106 is attached to the end. The lid 106 can be opened and closed from inside the building by an operation lever (not shown).

According to this ventilation device, the air flow control member 110
Performs the same action as in the above-mentioned embodiment and causes the air flow in the cabin space to flow out of the building. The airflow control body and the lid body may have a front and rear arrangement relationship in the through-cylinder which is a structure opposite to the above structure.

In FIG. 10, the operating levers (not shown) of the plurality of ventilation devices A, A ', B, B'disposed on the roof are connected to links 21, 21', 22, 22 ', 121, 121', 12 '.
2,122 'and wires 23,23', 123,12
FIG. 3 is a structural diagram of a roof ventilation system that is made to operate collectively by 3 ′, 124, and 125.

In the above figures, reference characters A and A'in the figure denote a pair of ventilation devices for the ridge, and B and B'denotes a pair of ventilation devices for the shed, which are arranged on both gables of the building. The lower ends of the operation levers of these ventilation devices A, A ', B, B'are pivotally supported by the operation links 21, 21', 121, 121 ', and the operation links 21, ... Are vertically extended wires 23. Two
L-shaped link 22, through 3 ', 123, 123'
22 ', 122, 122' are connected to one end. And the L-shaped links 122 of the cabin ventilation devices B and B ',
The other ends of the 122 'are connected to each other via the wires 124, 125 stretched in the horizontal direction, with the L-shaped links 22, 22' of the building ventilation devices A, A'as intermediaries. ing.

Therefore, for example, when the operation links 21 and 21 'are lowered so as to push up the operation levers of the building ventilation devices A and A'and the lid is opened to set the ventilation possible state, L
The lids of the respective cabin ventilation devices B and B ′ are also opened via the character-shaped links 22 and 22 ′ and the wires 124 and 125, etc. (see solid line arrows in the figure). On the contrary, when the L-shaped links 22 and 22 'are operated in the direction of closing the lids of the ventilation devices A and A'for ridges, all the ventilation devices B and B'for the sheds are also interlocked and the lids are closed. It is closed (see dashed arrow in the figure).

Of course, such interlocking of the roof ventilation device does not depend on the mechanical structure of the link and the wire,
The lower ends of the operating levers may be electrically controlled by connecting the lower ends of the operating levers to the rods that move forward and backward.

[0037]

As described above, according to the present invention, since the air flow control body formed by bundling a plurality of small diameter pipes is arranged in the passage through which the air flow of the apparatus main body passes, The flow resistance based on the length effectively blocks the inflow of a strong air flow from outside the building, while the drawing force when the outside pressure of the building becomes negative allows the air flow inside the building to flow out to the outside without difficulty. it can. Therefore, by combining several airflow control bodies, the outflow air amount can be made several times the inflow air amount, and the air inside the building can be discharged to the outside of the building as the entire roof surface. Ventilation of the building is promoted by the airflow rising from the lower part of the building.

The resistance to the inflow of the positive pressure air flow and the outflow amount of the air flow due to the negative pressure can be easily controlled by setting the inner diameter and the length of the small-diameter pipe, and accordingly by replacing the air flow control body.

According to the present invention, the ventilation of the building is promoted to discharge the hot air and humidity inside the building to the outside of the building depending on the season of the year (or the time of day). ,
In winter or the like, the lid can be closed to prevent the warm air inside the building from leaking out of the building, and the thermal insulation of the air retained inside the building can be used to maintain the room temperature.

In the present invention, the flow control in only one direction of the air flow is performed by the above-mentioned air flow control body and is not performed by opening and closing the valve whose one end is pivotally supported. There is no restriction, and even when it is applied to a ventilation device for a ridge, it is not necessary to purposely manufacture a roof, which can contribute to a significant reduction in the construction cost of this type of ventilation device. Rain does not easily enter due to the resistance of the airflow controller.

Further, the above-mentioned air flow control body has a simple structure and is free from troubles and can be easily replaced if necessary. Unlike a valve, it does not generate a collision noise, so it does not generate noise inside and outside the building, and it also exhibits a heat insulating effect by the air accumulated in the small diameter pipe.
