Means is provided for recirculating the air from the pipe or pipes back into the box for recooling, which is shown in the form of a fan located in a duct through a wall of the box and may be provided, if desired, with a thermostatic control.，下面是Cooling device for portable chest专利的具体信息内容。

权利要求

1. A cooling unit for a portable chest comprising a box adapted to sit in the chest on the bottom thereof, said box having surrounding walls of insulating material enclosing a chamber adapted to contain a refrigerant, a pipe having an open connection with said chamber through one of the walls adjacent the bottom thereof and extending outwardly therefrom to be disposed in the chest adjacent the bottom thereof for circulating air from the region of the refrigerant into the chest, means forming an opening through said one wall of the box into the chamber from within the chest, and means mounted on said one wall for circulating air through said opening by the refrigerant and for recirculating the air therefrom into the chest, said circulating means including an electrically operated blower mounted on said one wall of the box for causing the recirculation of the air through the opening, a housing connected with the blower, and means within the housing for electrically energizing the blower.

2. A cOoling unit according to claim 1, including an electrically operated blower within the wall opening for effecting recirculation of the air, and thermostatic means for controlling the blower.

3. A cooling unit according to claim 1, wherein the housing is elongated and detachably connected with the blower at one end, and encloses the electrically energizing means in the opposite end.

4. A cooling unit for a portable chest comprising a box adapted to sit in the chest on the bottom thereof, said box having surrounding walls of insulating material enclosing a chamber adapted to contain a refrigerant, means forming an opening through said one wall of the box into the chamber from within the chest, and means mounted on said one wall for circulating air through said opening by the refrigerant and for recirculating the air therefrom into the chest, a plurality of pipes connected at one end with one of the walls of the box and extending outwardly therefrom and having outer open ends to be disposed in the chest, and a thick sheet of plastic material enclosing the plurality of pipes and having a relatively flat surface adapted to form the bottom of the chamber of the chest to receive materials supported thereon, said sheet of plastic having the open ends of the pipes adjacent the top surface thereof.

5. The combination with a portable chest having surrounding walls, a bottom and a removable cover, of a cooling unit therefor comprising a box sitting upon the bottom of the chest, said box including surrounding walls of insulating material adapted to contain a refrigerant, at least one pipe connected at one end with one of the walls adjacent the bottom thereof and extending outwardly therefrom in the bottom portion of the chest, the pipe having an open outer end for circulating air from within the box into the chest, means forming an opening through a wall of the box in the upper portion of the chest for admitting air from within the chest into the box for cooling by the refrigerant, an electrically operated blower mounted on a wall of the box for causing the recirculation of the air through said opening, a housing connected with the blower, and means within the housing for electrically energizing the blower.

6. The combination according to claim 5 including a thick sheet of plastic material having at least one pipe extending lengthwise therethrough from a point adjacent the box to the outer end of the chest and having the outer end of said pipe open substantially at the upper surface of the sheet, and means connecting the inner end of the pipe with the interior of the box for circulation of air therethrough.

7. The combination according to claim 5, wherein the housing is elongated and detachably connected with the blower at one end, and encloses the electrically energizing means in the opposite end.
