Incubator

Abstract

An incubator includes: an insulated box including an incubation space surrounded by multiple inner faces; a humidifying unit that humidifies an incubation space; a first heating unit that heats a first inner face among the multiple inner faces, with electric power supplied; a second heating unit that heats a second inner face, different from the first inner face, with electric power supplied; and a control unit that controls the magnitude of electric power supplied to each of the first heating unit and the second heating unit. The control unit repeatedly changes the magnitude of electric power supplied to the first heating unit at first timing, and also repeatedly changes the magnitude of electric power supplied to the second heating unit at second timing different from the first timing.

1 . An incubator, comprising:
 an insulated box including an incubation space surrounded by a plurality of inner faces;   a humidifying unit that humidifies an incubation space;   a plurality of heating units that respectively heat the plurality of inner faces, with electric power supplied; and   a control unit that controls the magnitude of electric power supplied to each of the plurality of heating units, wherein   the control unit periodically and repeatedly changes the magnitude of electric power supplied to the plurality of heating units, at timing different for each of the plurality of inner faces.   
     
     
         2 . The incubator of  claim 1 , wherein:
 among the plurality of heating units, the heating unit that heats a bottom face of an incubation space among the plurality of inner faces is defined as a first heating unit;   the humidifying unit is provided near the bottom face; and   the control unit provides control so that electric power supplied to the first heating unit is greater than electric power supplied to each of the plurality of heating units except the first heating unit.   
     
     
         3 . The incubator of  claim 1 , wherein:
 among the plurality of heating units, the heating unit that heats a top board of an incubation space among the plurality of inner faces is defined as a first heating unit; and   the control unit provides control so that electric power supplied to the first heating unit is less than electric power supplied to each of the plurality of heating units except the first heating unit.   
     
     
         4 . An incubator, comprising:
 an insulated box including an incubation space surrounded by a plurality of inner faces;   a humidifying unit that humidifies an incubation space;   a plurality of heating units that heat the plurality of inner faces; and   a control unit that controls the magnitude of electric power supplied to each of the plurality of heating units, wherein   the control unit controls electric power supplied to each of the plurality of heating units so as to repeatedly change the temperature distribution on the plurality of inner faces at predetermined timing.
