Culture apparatus
First Claim
1. A culture apparatus comprising:
- a heat insulating box main body having a box shape and a culture space therein for culturing a sample;
a humidification water reservoir disposed at a bottom of the culture space, the humidification water reservoir storing humidification water to control humidity of the culture space;
a heater provided inside the heat insulating box main body for heating the humidification water reservoir;
a duct disposed in the culture space and at least along a wall of the heat insulating box main body;
a heat transfer condensation member penetrating the heat insulating box main body and having a condensation portion disposed inside the duct and a cooling portion disposed outside the heat insulating box main body; and
an electronic cooling element, based on Peltier effect, disposed on the cooling portion of the heat transfer condensation member for cooling the heat transfer condensation member,wherein moisture condensed on a surface of the condensation portion by cooling by the electronic cooling element is led into the humidification water reservoir disposed beneath the condensation portion.

Abstract
A culture apparatus is provided which can suppress condensation on walls of a culture space and the like to suppress adverse effects on a culture material. In the culture apparatus having a culture space formed in a heat insulating box main body, a humidification water reservoir for humidifying the culture space is disposed in the heat insulating box main body. A heat transfer condensation member in which a condensation portion at one end and a cooling portion at the other end are integrated is disposed such that the cooling portion is disposed outside the heat insulating box main body, while the condensation portion is disposed inside the culture space. The condensation portion is disposed so that condensed water on the surface thereof is led into the humidification water reservoir. The cooling portion has an electronic cooling element for cooling the cooling portion by the Peltier effect, to make moisture condensed on the condensation portion and a connection portion in the vicinity of thereof flow downward into the humidification water reservoir and repeatedly usable as humidification water.
