Heating cooker

Abstract

A heating cooker includes: a heating cooking compartment configured to accommodate a heating-target object; a housing having a suction port through which air is introduced, the housing being configured to accommodate the heating cooking compartment; a cooling fan configured to suction air from the suction port into a space between the heating cooking compartment and the housing; a heat generating unit configured to generate heat; and a flow channel section configured to allow air introduced from the suction port to flow in. The flow channel section includes a first flow channel section having a first flow channel opening facing the suction port, and a second flow channel section having a second flow channel area smaller than a first flow channel area of the first flow channel opening. The heat generating unit is disposed in the second flow channel section.

What is claimed is: 
     
         1 . A heating cooker comprising:
 a heating cooking compartment configured to accommodate a heating-target object;   a housing having a suction port through which air is introduced, the housing being configured to accommodate the heating cooking compartment;   a cooling fan disposed between the heating cooking compartment and the housing and configured to suction air from the suction port into a space between the heating cooking compartment and the housing;   a heat generating unit disposed between the heating cooking compartment and the housing, positioned between the suction port and the cooling fan, and configured to generate heat; and   a flow channel section extend in a first direction from the suction port toward the cooling fan and configured to allow air introduced from the suction port to flow in,   wherein   the flow channel section includes
 a first flow channel section having a first flow channel opening facing the suction port, and 
 a second flow channel section continuous with an end portion of the first flow channel section on the first direction side and having a second flow channel area smaller than a first flow channel area of the first flow channel opening, and 
   the heat generating unit is disposed in the second flow channel section.   
     
     
         2 . The heating cooker according to  claim 1 , wherein
 the flow channel section includes a third flow channel section continuous with an end portion of the second flow channel section on the first direction side, and   the third flow channel section has a third flow channel area larger than the second flow channel area.   
     
     
         3 . The heating cooker according to  claim 1 , wherein
 the housing includes a first wall portion having an opening through which the heating-target object passes toward an inside of the heating cooking compartment,   the first wall portion has
 the suction port, and 
 a discharge port discharging air blown out by the cooling fan to an outside of the housing, and 
 the discharge port is positioned on an opposite side of the suction port with respect to the opening. 
   
     
     
         4 . The heating cooker according to  claim 1 , wherein
 a length of the second flow channel section in a second direction is shorter than a length of the first flow channel section in the second direction,   the second direction indicates a direction orthogonal to the first direction and away from the heating cooking compartment,   a length of the second flow channel section in a third direction is shorter than a length of the first flow channel section in the third direction, and   the third direction indicates a direction orthogonal to the first direction and the second direction.   
     
     
         5 . The heating cooker according to  claim 4 , wherein the housing includes a first wall portion having an opening through which the heating-target object passes toward an inside of the heating cooking compartment,
 the heating cooker further comprising a door configured to open and close the opening,   wherein   the first wall portion has
 the suction port disposed apart from the opening in the second direction, and 
 a contact portion brought into contact with the door between the opening and the suction port, and 
   the heat generating unit is separated from the suction port in a direction opposite to the second direction.   
     
     
         6 . The heating cooker according to  claim 2 , wherein
 the third flow channel section has a third flow channel opening at an end portion in the first direction,   an end portion of the third flow channel opening in a second direction is positioned above an end portion of the first flow channel opening in the second direction, and   the second direction indicates a direction orthogonal to the first direction and away from the heating cooking compartment.   
     
     
         7 . The heating cooker according to  claim 1 , wherein the heat generating unit includes a light-emitting element configured to illuminate an inside of the heating cooking compartment.
