BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a poultry house for raising a large number of chickens.

0002

BACKGROUND OF THE INVENTION A poultry house needs to have uniform temperature distribution throughout and be sufficiently ventilated. For example, a poultry house housing 120,000 chickens is required to ventilate approximately 15,000 cubic meters of air per minute during the summer. To achieve this, conventional poultry houses have intake and exhaust ventilation openings in some parts of the building. A forced air fan is installed to force ventilation through the ventilation openings. A forced air fan takes in outside air through the intake vent and exhausts it through the exhaust vent.

0003

However, conventional poultry houses have the disadvantage that when the poultry house is forcibly ventilated, the room temperature near the inlet drops, making it impossible to maintain a uniform temperature inside the poultry house. There is a drawback that when cold air is inhaled, especially in winter, the temperature near the intake side ventilation port drops significantly.

[0004] The present invention was developed with the aim of solving this drawback, and an important objective of the present invention is to provide a poultry house that is sufficiently ventilated and can reduce the temperature difference within the room.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. However, the example shown below is an example of a poultry house for embodying the technical idea of this invention, and the poultry house of this invention has the material, shape, structure, and arrangement of the component parts as shown below. It is not specific. The poultry house of this invention can be modified in various ways within the scope of the claims.

[0008]Furthermore, in order to make the claims easier to understand, this specification uses numbers corresponding to members shown in the examples as "claims" and "means for solving the problem." It is added to the members shown in the "Column". However, the members shown in the claims are by no means limited to the members of the embodiments.

The poultry house shown in the vertical sectional view of FIG. 1 and the horizontal sectional view of FIG. 2 has four breeding blocks 2 in a building 1.
has been established.

The building 1 is divided into an attic ventilation room 4 and a breeding room 5 by a ceiling plate 3 horizontally fixed to the upper part. The ceiling board 3 is a heat insulating board and is fixed to the building 1 to partition a closed attic ventilation room 4.

The attic ventilation room 4 is located at the top of the sloping roof and has an outdoor ventilation fan 11 fixed therein. The outdoor ventilation fan 11 exhausts the air from the attic ventilation room 4 only in the summer.
It is not operated in winter. Therefore, the outdoor ventilation fan 11 is equipped with a shutter (not shown) that can close the opening in winter. In summer, when the shutter is opened and the outdoor ventilation fan 11 is operated, the warm air in the attic ventilation room 4 can be forcibly exhausted.

Furthermore, ventilation holes 6 are opened on both sides of the attic ventilation room 4. This ventilation port 6 takes in outside air. A plurality of ventilation holes 6 are provided on the side of the building 1 at regular intervals.

Furthermore, as shown in FIG. 2, the building 1 has an elongated overall shape. Ventilation ports 6 are opened at both ends of the elongated building 1. FIG. 3 shows a ventilation opening opened on one side of the building 1 shown in FIG. 2. In the building 1 shown in this figure, the entire end of the building 1 is opened to form a ventilation opening 6. A large number of forced air fans 10 are fixed to the ventilation port 6. In this way, the building 1 in which a large number of forced air fans 10 are installed in the ventilation openings 6 has a large number of forced air fans 10 that are operated.
The amount of ventilation can be adjusted by adjusting the number of 0's. If the number of forced air fans 10 to be operated is increased, the ventilation amount will be increased, and if the number of forced air fans 10 to be operated is decreased,
Ventilation volume decreases. The forced air fan 10 includes a shutter (not shown) that is closed when not in operation. Increase the amount of ventilation in the summer and reduce the amount of ventilation in the winter. In winter, the amount of oxygen that chickens need to breathe is usually adjusted to one-fifth to one-tenth of that in summer.

Furthermore, the building 1 shown in FIG. 2 also has a ventilation opening 6 at the other end in the figure. This ventilation hole 6
is provided with a water absorption filter 12 as shown in FIG. The water absorption filter 12 cools inhaled air using the heat of vaporization of water and supplies the cooled air to the breeding room 5 during the summer. Therefore, the water absorption filter 12 has voids through which air can pass. Further, water for cooling is supplied to the upper part of the water absorption filter 12, and this water is allowed to flow down, thereby cooling the air with the heat of vaporization of the water. An opening/closing door (not shown) is provided on the outside of the water absorption filter 12 to close the ventilation port 6 in winter.

[0015] Outside air drawn into the attic ventilation room 4 from outdoors passes through the ceiling plate 3 and flows into the breeding room 5. Therefore, an air intake duct 7 is opened in the ceiling plate 3. The air intake duct 7 and breeding block 2 are provided at specific positions. The poultry house shown in FIGS. 1 and 2 has rearing blocks 2 arranged in four vertical rows in a building 1. The rearing blocks 2 are arranged apart from each other, and air intake ducts 7 are opened in two vertical rows in the ceiling plate 3 located between the rearing blocks 2. An air mixing chamber 8 is provided below the air intake duct 7 between adjacent rearing blocks 2.

The air mixing chamber 8 supplies cold air flowing into the breeding room 5 from the air intake duct 7 of the ceiling plate 3 to the breeding room 5.
The air is mixed with warm air and supplied to the rearing block 2. Therefore, the width W of the air mixing chamber 8 is usually 50 cm to 2
m, preferably adjusted to a range of 1 m to 1.5 m.

[0017] In the rearing block 2, chickens are divided into a large number of compartments and reared. Therefore, the breeding block 2 is divided into a plurality of breeding rooms 5 by partition walls. Air circulation paths 9 are provided above and below the rearing room 5 in communication with an air mixing chamber 8.

The poultry house shown in FIGS. 1 and 2 includes a building 1 and four vertically elongated rearing blocks 2A, 2B, 2C,
2D is provided. The poultry house shown in these figures consists of two rows of rearing blocks 2A and 2B located on both sides, and one between 2C and 2B.
An air mixing chamber 8 is provided between D, and a partition wall is provided between the two central rows of rearing blocks 2B and 2C. An air intake duct 7 is opened above an air mixing chamber 8 provided between the breeding blocks 2A, 2B and the breeding blocks 2C, 2D.

The poultry house having this structure can effectively circulate air around the rearing block 2, as shown in FIG. However, it is also possible to provide an air mixing chamber 8 between the rearing blocks 2A, 2B, 2C, and 2D, and to communicate the air mixing chamber 8 with the inlet duct 7.

The poultry house shown in FIGS. 1 to 4 is operated under the following conditions in winter and summer. In the winter, the indoor temperature can be warmed by the body heat of the chickens being raised. However, when the chickens are small, a heater (not shown) is built in to heat the room. The heater is placed in the air mixing chamber.

[Winter Operation] ■ Close the shutter of the outdoor ventilation fan 11. ■ Close the opening/closing door of the ventilation port 6 equipped with the water absorption filter 12. ■ Operate some of the forced air fans 10. In the winter, the number of forced air fans 10 to be operated is reduced to 1/5 to 1/5 of the number in the summer.
Adjust to 1/10 range. When the forced air fan 10 is operated, outside air is sucked in in the following order. Ventilation opening 6 of the attic ventilation room 4 ↓ Attic ventilation room 4 ↓ Air intake duct 7 provided on the ceiling board 3 ↓ Air mixing chamber 8 ↓ Air circulation path 9 provided below the rearing block 2 ↓ Forced ventilation fan 10 ↓ Ventilation port 6 opened in breeding room 5

The air passing through the building in this order is mixed with cold outside air and warm indoor air in the air mixing chamber 8. Therefore, the cold outside air does not come into direct contact with the chickens, and the temperature difference within the room can be reduced. In addition, outside air passes through the attic ventilation room 4 and flows into the breeding room 5. Since the roof of the attic ventilation room 4 is heated by the sun, the air is heated to some extent and then flows into the rearing room 5.

[Summer Driving] Since the air temperature is high in summer,
The outdoor ventilation fan 11 is operated, and all the forced ventilation fans 10 provided in the ventilation openings 6 of the breeding room 5 are operated. All the opening/closing doors of the ventilation opening 6 provided with the water absorption filter 12 are opened.

The outdoor ventilation fan 11 exhausts hot air from the attic ventilation room 4. Therefore, it is possible to prevent the attic ventilation room 4 from being heated by solar heat. The air in the rearing room 5 is taken into the attic ventilation room 4 through an air intake duct 7, and outside air is taken in through the ventilation opening 6 opened in the attic ventilation room 4.

Outside air is drawn into the breeding room 5 from one side of the building 1 through the water absorption filter 12 . The water absorption filter 12 cools the air passing through it using the heat of vaporization of water. Therefore, water is supplied to the upper part of the water absorption filter 12. When the air humidity is extremely high, the air cooling effect due to the heat of vaporization is small and the relative humidity in the breeding room 5 becomes high, so water is not replenished to the water absorption filter 12.

In the poultry house of the present invention, it is not necessary to provide the air mixing chamber 8 between the rearing blocks 2. The poultry house shown in FIG. 5 has an air mixing chamber 8 connected to an air intake duct 7 between the rearing block 2 and the building wall 13. The air mixing chamber 8 is provided on the left side of the rearing block 2 in this figure. A gap is provided between the right side of the rearing block 2 and the building wall 13. In this poultry house, the air that flows into the breeding room 5 from the air intake duct 7 is mixed with room air in the air mixing chamber 8, passes through the air circulation path 9 provided below the breeding block 2, and then enters the breeding block 2. It rises through the space on the right side and flows into the air mixing chamber 8 from the air circulation path 9 on the upper side of the rearing block 2.

[0027]

[Effects of the Invention] The poultry house of this invention has the advantage of being able to ventilate the air in the breeding room under ideal conditions. This is because large amounts of cold air are inhaled and the chickens are not exposed to the cold air directly. In other words, in the poultry house of this invention, outside air does not directly enter the breeding room, but instead passes through the attic ventilation room and flows into the breeding room. It is configured so that it mixes with air and flows in a ring around the rearing block. Therefore, the temperature of the cold outside air that flows into the breeding room is raised in the air mixing chamber, and the warmed air can be supplied to the breeding block, which has the advantage of reducing the temperature difference between the room under the ceiling and the floor.
