Heating cooking apparatus

Abstract

A heating cooking apparatus includes a heating cooking chamber, a first heater, a first fan, a second heater, a second fan, and a control unit. The first fan blows first air heated by the first heater into the heating cooking chamber. The second heater heats second air. The second fan blows the second air heated by the second heater into the heating cooking chamber. The control unit controls the first heater, the first fan, the second heater, and the second fan. The control unit stops energization of the first heater and energizes the second heater before notification of completion of a preheating process. The preheating process indicates a process in which a temperature in the heating cooking chamber exceeds a threshold temperature at least once.

1 . A heating cooking apparatus comprising:
 a heating cooking chamber configured to accommodate an object to be heated;   a first heater configured to heat first air;   a first fan configured to blow the first air heated by the first heater into the heating cooking chamber;   a second heater configured to heat second air;   a second fan configured to blow the second air heated by the second heater into the heating cooking chamber; and   a control unit configured to control the first heater, the first fan, the second heater, and the second fan,   wherein the control unit stops energization of the first heater and energizes the second heater before making a notification of completion of a preheating process, and   the preheating process indicates a process in which a temperature in the heating cooking chamber exceeds a threshold temperature at least once before the object to be heated is accommodated in the heating cooking chamber.   
     
     
         2 . The heating cooking apparatus according to  claim 1 ,
 wherein the control unit stops energization of the first heater and stops driving of the first fan when a first predetermined period has elapsed from time of energization of the second heater, and   the first predetermined period indicates a period during which a temperature of the first heater decreases to a predetermined temperature or lower.   
     
     
         3 . The heating cooking apparatus according to  claim 1 ,
 wherein the control unit stops energization of the first heater and makes a notification of completion of the preheating process when a second predetermined period has elapsed from time of energization of the second heater, and   the second predetermined period indicates a period during which the temperature in the heating cooking chamber decreases to a temperature substantially identical to the threshold temperature.   
     
     
         4 . The heating cooking apparatus according to  claim 1 ,
 wherein the control unit drives the second fan after the notification of the completion of the preheating process.   
     
     
         5 . The heating cooking apparatus according to  claim 1 ,
 wherein the first heater is positioned at an upper portion of the heating cooking chamber,   the second heater is positioned on a predetermined side of the heating cooking chamber, and   the upper portion of the heating cooking chamber is different from the predetermined side of the heating cooking chamber.   
     
     
         6 . The heating cooking apparatus according to  claim 1 ,
 wherein the preheating process indicates a process in which a temperature of a predetermined region included in the heating cooking chamber exceeds the threshold temperature at least once, and   the predetermined region is disposed below the first heater and the first fan.   
     
     
         7 . The heating cooking apparatus according to  claim 1 , further comprising
 a temperature detection unit configured to detect a temperature in the heating cooking chamber,   wherein the control unit controls the first heater, the first fan, the second heater, and the second fan, based on a detection result of the temperature detection unit.   
     
     
         8 . The heating cooking apparatus according to  claim 7 , further comprising
 a third heater disposed in the heating cooking chamber,   wherein the control unit controls the third heater based on the detection result of the temperature detection unit.   
     
     
         9 . The heating cooking apparatus according to  claim 1 , further comprising
 a pull-out body on which the object to be heated is placed, the pull-out body configured to be pulled out from the heating cooking chamber,   wherein the control unit stops energization of the first heater and energization of the second heater when the pull-out body is pulled out.
