Hatcher with internally mounted exhaust duct and exhaust damper control means

In an egg hatcher structure having ceiling panel means, side wall panel means, front end panel means including at least one door, rear end panel means, and joining means for interconnecting the ceiling panel means, the side wall panel means and the front and rear end panel means to form a hatcher chamber, the improvement comprising:

• an air intake and exhaust vent disposed in the ceiling of the chamber for permitting the inflow of air into the chamber and for permitting the exit of air from within the chamber,
• air intake and exhaust control means including a first vertically disposed channel attached to the rear end panel means of the chamber and communicating with said air intake and exhaust vent for controlling the exit of internal air from within said chamber, and at least one other vertically disposed channel disposed adjacent said first channel and communicating with said air intake and exhaust vent for controlling the intake of external air into the chamber,
• environmental adjustment means disposed within said chamber near said vertically disposed channels for humidifying, heating and circulating air within said chamber, said environmental adjustment means including a mounting stand, a pair of electric fans mounted on said stand, at least one heating element mounted on said stand and positioned between said vertically disposed channel and said fans, and humidifying means positioned between said fans and said vertically disposed channels, said mounting stand cooperating with said vertical channels and said fans to create a restricted area high pressure zone of air to control the exit of air, the intake of air and the mixing of internal and external air.

An egg hatcher structure comprising a hatching chamber having at least a front wall, a rear wall and a pair of side walls;

• an air exhaust duct vertically disposed along said rear wall of said chamber and communicating with the exterior of said chamber for directing and controlling the flow of internal air out of the hatching chamber, said air exhaust duct comprising a front wall interconnecting two side walls, said front wall spaced from said rear wall of said chamber and having at least one opening to permit the air inside the chamber to be exhausted out of the chamber, said opening being covered by a damper slidably mounted on the front wall of said exhaust duct to thereby vary the size of said opening for directing and controlling the flow of internal air out of the hatching chamber, said air intake duct communicating with the exterior of the chamber and comprising a side wall mounted on said rear wall of said chamber and spaced laterally from one side wall of said exhaust duct and a front wall pivotally connected to said side wall and releasably connectable to said front wall of said exhaust duct, said side wall of said air intake duct having at least one opening to allow external air to enter said hatcher chamber;
• environmental adjustment means for heating, humidifying and circulating air within said chamber;
• and environmental adjustment control means for monitoring the temperature, moisture and air circulation levels within the chamber and adjusting the environmental adjustment means and said dampers to maintain the temperature, moisture and air circulation at prescribed levels.

An egg hatcher structure comprising a hatching chamber having at least a front wall, a rear wall and a pair of side walls;

• airflow control means for directing and controlling the flow of external air into the hatching chamber and for directing and controlling the flow of internal air out of the hatching chamber;
• environmental adjustment means for heating, humidifying and circulating air within said chamber;
• environmental adjustment control means for monitoring the temperature, moisture and air circulation levels within the chamber and adjusting the environmental adjustment means and airflow control means to maintain the temperature, moisture and air circulation at prescribed levels;
• and alignment means mounted along the bottom of the rear wall of the chamber for precisely positioning said environmental adjustment means relative to said airflow control means, said alignment means including a mounting bracket having two vertical side walls interconnected by a horizontal bottom portion, said vertical side walls each having a cut out portion and a roller disposed at the bottom and top of said cut out portions.

An egg hatcher structure comprising a hatching chamber;

• airflow control means for directing and controlling the flow of external air into the hatching chamber and for directing and controlling the flow of internal air out of the hatching chamber;
• environmental adjustment means for heating, humidifying and circulating air within said chamber;
• said environmental adjustment means including air circulation means for circulating air within the hatcher chamber, heating means for heating air circulating within the hatcher chamber, and humidifying means for moisturizing the air circulating within the hatcher chamber;
• a mobile cart upon which said environmental adjustment means is mounted, said mobile cart movable for placement and removal of said environmental adjustment means from said hatcher chamber, said mobile cart including enclosure means which cooperates with said airflow control means and said air circulation means to create a restricted area high pressure air zone within the chamber for controlling the exhaust of internal air out of the chamber and the intake of external air into the chamber;
• and, environmental adjustment control means for monitoring the temperature, moisture and air circulation levels within the chamber and adjusting the environmental adjustment means and airflow control means to maintain the temperature, moisture and air circulation at prescribed levels.
