2. Description of the Related Art As is well known, a windless poultry house requires a ventilator communicating with the outside in order to ventilate the inside air. The present applicant discloses Japanese Patent Application Laid-Open No. 9-27323.
The ventilating device for a windless poultry house proposed in Japanese Patent Publication No. 6 is formed with an exhaust port communicating the indoor side and the outdoor side at the upper part of the wall, and has a bottom part and a side part above the outdoor part of the wall. A protective frame is provided so as to cover the outdoor side of the exhaust port, and the upper end of the side portion of the protective frame is located above the exhaust port and above the eaves of the roof of the building. This is a configuration that is extended.

[0003]

However, in the above-mentioned conventional ventilating apparatus, since the open upper surface of the protective frame is not sufficiently closed, it is necessary to reliably rear the internal chickens as a windowless poultry house. Can not. In other words, the windless poultry house breeds and lays eggs by breeding thousands, tens of thousands or hundreds of thousands of chickens inside, and controls indoor temperature, humidity and ventilation and ensures the introduction of sunlight. The breeding of chickens has been promoted by changing the daytime and nighttime by turning on and off artificial lighting to prevent this and increasing the egg production rate. In the conventional ventilation device, since the open upper surface of the protection frame is not closed, the sunlight is reflected several times inside the protection frame and is introduced into the room through the exhaust port. Therefore, the breeding chicken is given a recognition that it is bright even with the reflected light of the sun, and it is not possible to distinguish day and night, so that breeding management cannot be performed. In particular, chickens bred in the vicinity of the exhaust port receive reflected light of the sun during the day, so that it is difficult to reliably breed them.

In summary, according to the present invention, an exhaust port is provided at the upper part of a wall surface for communicating between the indoor side and the outdoor side, and a bottom part and a side part are provided above the outdoor side of the wall. A protective frame is provided that opens to the upper surface so as to cover the outdoor side of the exhaust port, and the upper end of the side portion of the protective frame is located above the exhaust port and above the eaves of the roof of the building. The upper end of the side portion is provided with a closing portion that shields the upper part of the upper surface opening of the protective frame body from being reflected by the sun rays to prevent the sunlight from being introduced into the indoor side. It is characterized by the following.

Therefore, no matter what direction the sun irradiates, it is possible to reliably shut off the sun's rays and prevent the reflected light from being introduced into the poultry house. And precise control controlled by a computer enables high breeding efficiency and long-life breeding. Even if the poultry house is constructed in any direction, such as southward or northward, sunlight can be reliably prevented from being introduced into the poultry house, so that there is no restriction on the installation place of the poultry house. Also, even if there is not only strong wind and rain from above, but also strong horizontal wind or heavy rain, the outside of the exhaust port is covered by a closed part, eaves, a protective frame, etc. Since the tip of the closing portion extends above the room, the interior of the poultry house can be reliably protected. Furthermore, since the exhaust port and the top opening are open directly into the poultry house, the exhaust capacity is extremely high, and the ventilation efficiency inside the poultry house can be significantly improved. Therefore, especially in a windowless poultry house without windows, using artificial lighting to prevent irradiation of the sun rays and using it as a large poultry house where chickens can not be bred without sufficient ventilation, It is easy to maintain and maintain, can be built inexpensively in a short time, and has high practical value.
