Abstract

A cooling apparatus includes a first power supply, a second power supply, and a power switching control unit configured to switch a power supply from the first power supply to the second power supply near the time when the temperature of a compartment starts decreasing.

Claims

exact text as granted — not AI-modified
1 . A cooling apparatus comprising:
 a first power supply;   a second power supply; and   a power switching control unit configured to switch a power supply from the first power supply to the second power supply near time when a temperature of a compartment starts decreasing.   
     
     
         2 . The cooling apparatus according to  claim 1 , wherein the power switching control unit switches the power supply from the second power supply to the first power supply after a lapse of a specified time. 
     
     
         3 . A cooling apparatus comprising:
 a first power supply;   a second power supply;   a door configured to open/close a compartment; and   a power switching control unit configured to switch a power supply from the first power supply to the second power supply near time when the door is closed.   
     
     
         4 . The cooling apparatus according to  claim 3 , wherein the power switching control unit switches the power supply from the first power supply to the second power supply at the time when the door is closed. 
     
     
         5 . The cooling apparatus according to  claim 3 , wherein the power switching control unit switches the power supply from the first power supply to the second power supply at time when a temperature of the compartment starts decreasing after the door is closed. 
     
     
         6 . The cooling apparatus according to  claim 3 , wherein when a temperature of the compartment is increased to at least a specified temperature due to opening of the door, the power switching control unit switches the power supply from the first power supply to the second power supply near the time when the door is closed. 
     
     
         7 . The cooling apparatus according to  claim 3 , wherein the power switching control unit switches the power supply from the second power supply to the first power supply after a lapse of a specified time. 
     
     
         8 . The cooling apparatus according to  claim 3 , wherein the second power supply is a chargeable power storage device, and the power storage device is charged under the control of the power switching control unit. 
     
     
         9 . A control method provided for a cooling apparatus comprising:
 a first power supply; and   a second power supply,   wherein a power supply is switched from the first power supply to the second power supply near time when a temperature of a compartment starts decreasing.
