Abstract
An automatic incubator comprises a chamber surrounded by a water jacket and insulation and provided with temperature and gas level sensors, a gas injection solenoid valve and separate water jacket and air heaters together with microprocessor proportional-integral-derivative control for regulating temperature and gas concentration within the chamber. A fan is provided to circulate gas within the chamber and distribute heat. Manual set controls for selecting desired temperature and gas levels are provided as well as temperature and gas level displays, high and low temperature and gas indicators, and a low water jacket level indicator.
Claims15
An automatic incubator comprising:
- a chamber having an entry door;
- a heat storage means in surrounding relation to said chamber;
- a first heater means for controllably heating said heat storage means;
- a second heater means disposed within said chamber for controllably heating the gaseous interior of said chamber;
- sensing means disposed in said chamber;
- and
- control means for operably actuating said heater means in response to input from said sensing means for controlling the temperature within said chamber to provide rapid recovery after access to said incubator via said entry door.
