Culture apparatus
A culture apparatus that cultivates a culture, which includes an outer case, an inner case configured with metal plates inside the outer case, a heater outside the inner case, and a door, which opens/closes an opening formed in front faces of the inner cases, includes: shelf rests on which side parts of a bottom plate of a shelf are to be placed, the shelf rests formed by pressing on side plates of the inner case; and a heat transfer sheet attached to an outer surface of at least one of the side plates and configured to transfer heat of the heater to the inner case, the heat transfer sheet including slits, intermittently formed, to bend the sheet to depressions of the outer surface of the side plate at positions corresponding to the shelf rests, after the heat transfer sheet is attached to the outer surface.
1. A culture apparatus configured to cultivate a culture comprising:
an outer case;
an inner case configured with metal plates, the inner case being arranged inside the outer case;
a heater arranged outside the inner case;
a door configured to open and close an opening formed in a front face of the inner case;
shelf rests on which side parts on both sides of a bottom plate of a shelf are to be placed, the shelf rests being formed, by press working, in side plates on both sides of the inner case; and
a heat transfer sheet attached to an outer surface of at least one of the side plates of the inner case, the heat transfer sheet configured to transfer heat of the heater to the inner case, the outer surface having first depressions at locations corresponding to the shelf rests,
wherein the heat transfer sheet includes a plurality of first slits configured such that a part of the heat transfer sheet is bent to the first depressions, after the heat transfer sheet is attached to the outer surface of at least one of the side plates of the inner case, the plurality of first slits being intermittently formed.
2. The culture apparatus according to claim 1 , wherein the heat transfer sheet includes release holes configured to allow gas to be released, the gas being generated when the heat transfer sheet is attached to the outer surface of at least one of the side plates of the inner case.
3. The culture apparatus according to claim 2 , wherein the shelf rests are in a long shape, and
the first slits are formed by cutting the heat transfer sheet along a longitudinal direction of the shelf rests.
4. The culture apparatus according to claim 2 , wherein
the shelf rests are in a long shape, and
the first slits are formed by cutting the heat transfer sheet along a longitudinal direction of the shelf rests.
5. The culture apparatus according to claim 2 , wherein:
the at least one of the side plates of the inner case further includes stoppers formed by press working such that the stoppers protrude toward inside the inner box, the stoppers being configured to limit movement in a vertical direction of a shelf placed on immediately lower shelf rests,
the release holes are provided at positions facing second depressions, the second depressions being formed in the first depressions at locations corresponding to the stoppers, and
the heat transfer sheet further includes second slits configured such that a part of the heat transfer sheet is bent to the second depressions, after the heat transfer sheet is attached to the outer surface of the at least one of the side plates of the inner case.
6. The culture apparatus according to claim 3 , wherein
the side plates of the inner case each have further formed therein stoppers by further depressing the first depressions by press working, the stoppers being configured to limit movement in a vertical direction of the shelf placed on the shelf rests,
the release holes are provided at positions facing second depressions, the second depressions being formed in the first depressions with the stoppers being formed, and
the heat transfer sheet further includes second slits to bend the heat transfer sheet in such a manner as to be further attached to the second depressions, after being attached to the outer surface of the side plate of the inner case.
7. The culture apparatus according to claim 4 , wherein
the side plates of the inner case each have further formed therein stoppers by further depressing the first depressions by press working, the stoppers being configured to limit movement in a vertical direction of the shelf placed on the shelf rests,
the release holes are provided at positions facing second depressions, the second depressions being formed in the first depressions with the stoppers being formed, and
the heat transfer sheet further includes second slits to bend the heat transfer sheet in such a manner as to be further attached to the second depressions, after being attached to the outer surface of the side plate of the inner case.
