BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation method and a ventilation apparatus for a building used as a livestock barn for raising poultry, raising pigs, or a large-scale factory or warehouse.

[0002]

2. Description of the Related Art A windowless livestock building without a window on a wall, which has been conventionally known, is disclosed in Japanese Patent Application Laid-Open No. 63-54543 proposed by the present applicant. The outside air is introduced into the air passage formed in the attic and blown out from the ceiling into the interior of the building, and is circulated in the interior of the building to exhaust air from the upper part of the wall or from the ridge through the attic.

[0003]

However, in the building ventilator having the above-described structure, the exhaust port cannot be set large, so that the amount of exhaust per unit time is limited. However, sufficient ventilation effect cannot be expected in the room. In addition, in a large-scale building such as a poultry house that breeds hundreds of thousands of chickens, for example, the air does not sufficiently circulate in the room unless the blowing pressure of the air blown from the ceiling into the building is extremely high. The size of the fan mechanism for introducing the fan becomes large and noise is generated, and inexpensive ventilation equipment cannot be installed. Also,
If the room is not sufficiently ventilated, there will be a temperature difference between the top and bottom of the room, the internal atmosphere will be different, the breeding condition of the chicken will be different, the egg laying rate will decrease, and in extreme cases the chicken will die Sometimes. Therefore, there is a demand for a ventilating device for a building that can efficiently and reliably ventilate a room with extremely simple and inexpensive equipment even for a large-scale building such as a poultry house.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in the drawings. A building 1 according to the present invention has a long gable shape and is shown as a chicken house in the drawings. However, it may be a piggery, or a factory or a warehouse.

[0006] Between the roof 2 and the ceiling 3 of the building 1, a lateral partition wall 4 separates an exhaust path 5 on the upper side and an air path 6 on the lower side so that air does not flow therethrough. Along the length direction of the building 1, a fan mechanism 7 for forcibly introducing outside air into the air passage 6 is installed on one of the wives of the building 1.

The ceiling 3 has a room 8 in the building 1.
And the air path 6 are communicated with each other, and slit-shaped openings 9 are opened at appropriate intervals in the width direction of the building 1 so as to extend along the length direction of the building 1. The air which has been introduced into the room and has a raised pressure is blown out from the opening 9 into the room 8 from above.

According to the present invention, a first vertical partition wall 11 extending from the roof 2 to the floor 10 is provided in the interior 8 of the building 1 in the longitudinal direction of the building 1. The exhaust passage 5, the intake passage 6, and the room 8 are divided into right and left. If the width of the building 1 is not so long, the number of the first partition walls 11 may be about one or two, but if the width of the building 1 is sufficiently long, a plurality of the first partition walls 11 may be provided. It is preferable to provide the compartment 8 to divide it into a plurality.

The first partition wall 11 has column members 12 arranged at appropriate intervals along the length direction inside the building 1,
A metal plate, a wooden plate, a resin plate, or the like may be stretched from one roof to the floor 10 on one surface of the column members 12 arranged in parallel. Therefore, the exhaust path 5, the air intake path 6, and the room 8 are divided into right and left by the first partition wall 11 provided along the length direction of the building 1.

A second partition wall 13 is provided in the air passage 6 so as to be close to the first partition wall 11 so that the first partition wall 11 and the second partition wall 13 face each other. At intervals, a communication path 14 that connects the upper exhaust path 5 and the lower chamber 8 is formed in the vertical direction.

The second partition wall 13 is provided at a portion of the other surface of the column member 12 on which the first partition wall 11 is provided, which is located in the air passage 6, similarly to the first partition wall 11. Metal plate,
It can be configured by stretching a wooden board, a resin board, or the like. For this reason, the communication passage 14 is configured to have the same width as the thickness of the pillar 12.

Therefore, when the fan mechanism 7 is driven, outside air is forcibly introduced into each of the air passages 6 which are partitioned by the first partition wall 11 and are arranged in the horizontal direction, thereby increasing the pressure. Downward air is blown out from the section 9 into the room 8 and circulates, and rises up each communication path 14 and flows into the exhaust path 5.

In the embodiment shown in the drawings, a poultry manure drying chamber 15 is provided on the other side of the building 1 where the fan mechanism 7 is not provided, and the end of the exhaust path 5 is opened. Therefore, the air that rises from the room 8 to the communication path 14 and flows into the exhaust path 5 is introduced into the chicken dung drying room 15, so that if the building 1 is a poultry house, a large number of birds bred in the room 8 The heated air heat-exchanged by the chicken is guided to the chicken dung drying chamber 15 and circulates, so that the chicken dung can be dried effectively. However, instead of installing the chicken dung drying chamber 15 on the wife's side of the building, the air in the exhaust passage 5 may be discharged directly from the wife's face or the ridge of the roof 2 to the outside.

In another embodiment of the present invention shown in FIG. 5, the exhaust passage 5 is provided only in the intake passage 6 and the room 8 without providing the first partition wall 11, and the exhaust passage 5 is provided in a horizontally elongated one. This is a configuration in the form of a book duct. When the exhaust path 5 is configured as described above, the height of the first partition wall 11 is reduced by the height of the exhaust path 5, so that the amount of wall material used is reduced, and the labor for building is also reduced. , Construction costs can be reduced.
In addition, since the exhaust path 5 is in the form of a horizontally long and long duct, the flow of the air to be exhausted is increased, and an ejector action is generated in the communication path 14, so that the exhaust efficiency can be improved. Efficiency can be increased.

In another embodiment of the present invention shown in FIG. 6, a first partition wall 11 is provided only in the air passage 6 so as to face the second partition wall 11.
A communication passage 14 is formed by the partition wall 13, and in the room 8, a vertical shielding wall 16 is provided along the length direction of the building 1 in the middle of the thickness of the column member 12, and the upper end of the shielding wall 16 is provided. This is a configuration in which the portion protrudes to the lower part of the communication path 14. Therefore, the interior 8 is connected to the exhaust passage 5 from the communication passage 14 on the left and right.
, The circulating air is guided by the right and left shielding walls 16 and guided from the communication path 14 to the exhaust path 5, so that not only the ventilation efficiency in the room 8 can be further improved, but also Construction costs can be reduced.

In FIGS. 5 and 6, the reference numerals which are not explained are the same as those of the embodiment shown in FIGS. 1 to 4 and the explanation is omitted.

Although the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, but may be modified in any way unless the structure described in the claims is changed. Can be implemented. For example, if the first partition wall 11 is not provided even in the room 8, the room 8 is opened and the space is widened, so that the room 8 can be used as a building for another purpose.

[0018]

In summary, according to the present invention, an exhaust path is formed on the upper side and an air path is formed on the lower side along the longitudinal direction of the building between the roof and the ceiling of the building. In the entry airway, a communication passage that connects the room inside the building located below and the exhaust passage located above is formed vertically along the length of the building, and lifts in the airway. A method of ventilating a building, characterized in that the compressed air is blown out into the room of the building, and the room air is guided from the communication passage to the exhaust path and exhausted to the outside, and The present invention relates to a ventilation device for performing a ventilation method.

Therefore, the amount of exhaust air per unit time can be increased by the exhaust path. Therefore, by increasing the amount of outside air introduced into the intake path, the indoor space in the building can be increased in proportion to the amount of outside air introduced. Can significantly enhance the ventilation effect. In addition, even in a large-scale building, the size of the fan mechanism can be reduced, so that pollution due to noise can be reduced. Moreover, not only is the use of pillars and heat insulating walls halved, but also it is not necessary to provide heat insulating materials at the interior boundaries other than the outer walls, so that buildings can be constructed at low construction costs, especially It will be of high practical value in livestock barn for poultry raising and pig raising.
