Problems solved by technology

However, while such configurations can be effective in heating an incubator, they do not necessarily provide as strict a control on the incubator temperature as is desirable for consistent results.
Conventional air heater type incubators lack the temperature stability of the water jacket type.

Embodiment Construction

[0029]A first embodiment of the insulated enclosure or chamber of the present invention is shown generally at 1 in FIG. 1, with additional embodiments shown generally at 1A in FIG. 5, at 1B in FIG. 7, at 1C in FIG. 8, at 1D in FIG. 9, at 1E in FIG. 10, at 1F in FIG. 11, at 1G in FIG. 13, and at 1H in FIG. 15. Chamber 1 is configured to serve as an incubator, environmental chamber, oven, refrigerator or freezer. Chamber 1 includes a main body or container 3, a storage interior chamber 4 defined by container 3, a door 5 and a control assembly 7 secured to and seated atop container 3. Container 3 in the exemplary embodiment is in the form of a five-sided or five-walled box-like structure wherein the forward terminal ends of four of these walls define an entrance opening 6 (FIG. 2) of interior chamber 4. Upper and chamber 4. Upper and lower horizontal shelves 2 are disposed within interior chamber 4 extending between three of the walls of container 3 and suitably supported therein for s...

Abstract

An insulated chamber having an interior chamber for storing items therein includes a phase change material to facilitate controlling the temperature of the interior chamber and the items. A heating device or cooling device may be used to melt or freeze the phase change material, which may be in various locations such as the walls of the chamber or packets which may serve as shelves and may be removable from the interior chamber with the items thereon. The packets may have recesses for receiving the items. The phase change material may be within capsules which may be within a liquid or a solid matrix. Controls may be provided to control humidity and carbon dioxide within the interior chamber.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims priority from U.S. Provisional Application Ser. No. 61 / 359,143 filed Jun. 28, 2010; the disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Technical Field[0003]The present invention relates generally to insulated chambers such as incubators, environmental chambers, freezers, refrigerators and ovens. More particularly, the present invention relates to an insulated chamber in which a phase change material enhances temperature control.[0004]2. Background Information[0005]Insulated chambers may be used for a variety of purposes. For instance, such chambers may include incubators, environmental chambers, freezers, refrigerators and ovens. Incubators are typically used for growing cultures in a controlled environment, wherein temperature, humidity, and atmospheric gas concentration are maintained at selected levels. For certain applications it is highly desirable to have both tempe...
