Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a constant temperature device with an illuminator used for culturing animal and plant cells and bacteria, and for growing plants.

(B) Conventional Technology As a technology prior to the present invention, there is a thermostatic device described in JP-A-59-42882. The thermostatic device is formed by accommodating a box body made of a highly heat-conductive material equipped with a lighting device in an air-conditioned chamber.

As a result, the amount of air used for culturing and growing is small, and the lighting device that also serves as a heat source is arranged in an air-conditioned chamber, resulting in poor air conditioning efficiency.

Further, there is a constant temperature device with an illuminating body in which an illuminating device exposed on a side wall formed by a transparent plate of a constant temperature box for air conditioning is directly mounted. However, since it is necessary to support a heavy lighting device, it is necessary to improve the strength of the constant temperature box, which complicates the structure. Also, from the side wall where the illuminating body is attached, the inside of the constant temperature box cannot be observed even though it is formed of a translucent plate,
It should always be taken out from the thermostat box. In addition, since the illuminating body is exposed, light is leaked to the surroundings, which has a great influence on other devices and is inconvenient to use.
