[0008] A temperature controlling unit according to a first aspect of the present invention is a temperature controlling unit which comprises: an insulative lid; and a temperature controll

Problems solved by technology

The container which cools the interior by solid carbon dioxide, a cold reserving agent or the like, however, has a problem such that as solid carbon dioxide sublimes or the cold reserving agent melts down due to heat from stored items or heat from the exterior of the container, it takes a lot of trouble for refilling solid carbon dioxide or replacing the cold reserving agent to keep the stored items in the container for a long time.
In the case of using solid carbon dioxide, its repetitive use over a long period of time increases not only the amount of the solid carbon dioxide, which eventually increases the running cost, but also the density of carbon dioxide in the atmosphere as the solid carbon dioxide gasifies due to the sublimation.
While the containers of the above described Japanese publications neither require such a labor nor suffer such an environmental burden, they are unable to store items with larger volumes than the internal volumes of the containers due to the pre-limited inner volumes, and they are relatively heavy and expensive.
Accordingly, there is a problem in using them for transportation.

first embodiment

[0043] the present invention will now be explained with reference to FIGS. 1 to 4. Reference number 1 denotes a container, and the container 1 comprises a temperature controlling unit 2 and an insulating container 3.

[0044] The temperature controlling unit 2 comprises a lid 4 formed with a through-hole 4A in a substantial center thereof, and a temperature controlling subunit 5. The lid 4 is made of an insulative foam synthetic resin in a tabular shape, in a single-piece manner, and its entire surface is covered with an infrared reflection film as an infrared reflection layer. A step member 4B is formed on the through-hole 4A, and a later described base 8 of the temperature controlling subunit 5 is placed on the step member 4B. The temperature controlling subunit 5 comprises a Stirling refrigerator 6 as a temperature controlling device, a casing 7 for containing the Stirling refrigerator 6, and the base 8 for supporting the Stirling refrigerator 6 and the casing 7. The Stirling refrig...

second embodiment

[0050] Next, how to assemble the temperature controlling unit 21 of the second embodiment will now be explained. First, the temperature controlling subunit 23 is assembled. To be more precise, the heat exhausting sink 10 is attached to the heat exhausting portion 6C of the Stirling refrigerator 6, the heat conductive block 26 is attached to the heat absorbing portion 6B of the cylindrical portion 6A, and the outer circumferences of the heat absorbing portion 6B and the heat conductive block 26 are covered with the insulating material 28 and the sealing member 29. The sealing member 12 is attached to the circumference of the heat exhausting sink 10, the Stirling refrigerator 6 is laterally accommodated in the casing 24. At this time, the heat conductive block 26 is allowed to pass through the through-hole 24D. The fan 11 is attached to the exhausting opening 24C of the casing 24. The casing 24 accommodating the Stirling refrigerator 6 is attached to the base 25 by the attachment memb...

third embodiment

[0053] Next, the present invention will now be explained with reference to FIG. 6. The same structure portions as the aforementioned embodiments are denoted by the same reference numbers, and explanations thereof will be omitted. Explanations of the similar effectiveness will be also omitted here. Reference number 30 denotes a container, and the container 30 comprises a temperature controlling unit 31 and a lid 32. The lid 32 is made of an insulative foam synthetic resin in a tabular shape, in a single-piece manner, and its entire surface is covered with an infrared reflection film as an infrared reflection layer. The lid 32 is openably and closably attached to an opening 33F of a later described insulating container 33 which constitutes the temperature controlling unit 31.

[0054] The temperature controlling unit 31 comprises an insulating container 33 and the temperature controlling subunit 23. The insulating container 33 is so structured as to include a right wall 33A, a left wall ...

Abstract

A temperature controlling subunit, which includes a Stirling refrigerator as a temperature controlling device, is attached to an insulative lid. A heat absorbing sink which constitutes a temperature control effect member of the temperature controlling subunit is thermally exposed at one surface side of the lid. The resultant structure functions as a temperature controlling unit. Accordingly, the interior of the insulating container of an arbitrary size can be cooled with its opening closed and sealed by the temperature controlling unit, and items to be stored can be continuously stored for a longer time compared with a case of cooling the interior of the insulating container with solid carbon dioxide and a cold reserving agent conventionally used.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a temperature controlling unit and a container using the same, and more particularly, to a container for transportation. [0003] 2. Description of the Related Art [0004] In general, a conventional container for transportation comprises an insulating container and a cover, both made of foam synthetic resins, and holds solid carbon dioxide, a cold reserving agent or the like inside, thereby cooling the interior of the container. Japanese Unexamined Patent Publication No. 2000-304402 discloses an electronic cooling or heating container comprising an insulating container with an openable and closable lid, in which the insulating container has a built-in cooling or heating unit (corresponding to a temperature controlling unit of the present invention). Japanese Registered Utility Model No. 2553022 discloses a cooling or heating container with a lid which openably and closably covers the op...
