Cooking appliance

Abstract

A machine room cooling structure of an oven which relatively enlarges the inner volume of a cooking room by lowering the height of the machine room is provided. The machine room cooling structure includes a fan forcibly blowing air of the machine room, a motor driving the fan, an exhaust duct guiding air of the machine room to an area in front of the oven, and a support bracket to install the motor at a suction hole of the exhaust duct, the support bracket includes a base unit, a motor combining unit on which a core of the motor is placed, and bridge parts connecting the base unit and the motor combining unit, and the motor combining unit is formed such that the height of the lower end of the core is equal to or lower than the height of the upper end of the exhaust duct.

What is claimed is: 
     
         1 . A cooking appliance comprising:
 a cooking room to accommodate an object to be cooked;   a machine room provided above the cooking room;   an exhaust duct including a suction hole, which sucks in air from the machine room, and a discharge hole, which discharges the sucked air to an area in front of the machine room;   a fan forcibly blowing air of the machine room;   a motor including a stator and a rotor, provided above the fan and driving the fan, the stator including a bobbin on which a coil is wound and a core forming a magnetic field according to current applied to the coil; and   a support bracket which is provided at the suction hole, and which supports the motor such that a height of a lower end of the core is equal to or lower than a height of an upper end of the exhaust duct.   
     
     
         2 . The cooking appliance according to  claim 1 , wherein the support bracket includes a base unit supported by the exhaust duct around the suction hole, a motor combining unit separated from the base part so that air passes through a gap between the base unit and the motor combining unit, and bridge parts connecting the base unit and the motor combining unit,
 wherein the bridge parts are formed horizontally, or are inclined downwardly in a direction from the base unit to the motor combining unit.   
     
     
         3 . The cooking appliance according to  claim 2 , wherein the motor combining unit includes a core support part on which the core is mounted, and a core guide part extended upwardly from the core support part so as to form an accommodation space accommodating the core together with the core support part,
 wherein a height of an upper end of the core support part is equal to or lower than the height of the upper end of the exhaust duct.   
     
     
         4 . The cooking appliance according to  claim 3 , wherein the base unit includes a bell-mouthed part to prevent noise of air sucked into the exhaust duct. 
     
     
         5 . The cooking appliance according to  claim 4 , wherein the base unit further includes a planar part extended horizontally to the outside of the bell-mouthed part, and a curved part extended upwardly from the planar part so as to have a gentle inclination and placed on the exhaust duct. 
     
     
         6 . The cooking appliance according to  claim 1 , wherein the radius of the suction hole is greater than the radius of the fan. 
     
     
         7 . The cooking appliance according to  claim 1 , wherein the support bracket is integrally formed. 
     
     
         8 . A cooking appliance comprising:
 a cooking room to accommodate an object to be cooked;   a machine room provided above the cooking room;   a fan forcibly blowing air of the machine room;   a motor including a stator and a rotor, provided above the fan and driving the fan, the stator including a bobbin on which a coil is wound and a core forming a magnetic field according to current applied to the coil; and   an exhaust duct to suck in air from the machine room and to discharge the sucked air to an area in front of the machine room, the exhaust duct including a motor combining unit which supports the motor such that the height of the lower end of the core is equal to or lower than the height of the upper end of the exhaust duct.   
     
     
         9 . The cooking appliance according to  claim 8 , wherein the exhaust duct includes bridge parts supporting the motor combining unit,
 wherein the bridge parts are formed horizontally, or are inclined downwardly in a direction toward the motor combining unit.   
     
     
         10 . The cooking appliance according to  claim 8 , wherein the motor combining unit includes a core support part on which the core is mounted, and a core guide part extended upwardly from the core support part so as to form an accommodation space accommodating the core together with the core support part,
 wherein a height of an upper end of the core support part is equal to or lower than the height of the upper end of the exhaust duct.   
     
     
         11 . The cooking appliance according to  claim 8 , wherein the exhaust duct includes a bell-mouthed part forming a suction hole. 
     
     
         12 . The cooking appliance according to  claim 8 , wherein the exhaust duct is integrally formed.
