High frequency heating apparatus having a range hood

Abstract

A high frequency heating apparatus with a range hood, which has an opening for suctioning or exhausting air and a cover for closing the opening, includes a microcomputer control unit for controlling an automatic opening/closing operation of the cover, a control panel for setting an operation of the apparatus, a display unit for displaying the control status, and a detecting unit for detecting an exhaust direction of a blower. The exhaust direction of the blower can alternate between indoor circulation and outdoor ventilation and, based on a detection signal from the detecting unit, the control unit opens the cover when the exhaust direction of the blower is set for indoor circulation while the control unit closes the cover when the exhaust direction of the blower is set for outdoor ventilation.

1 . A high frequency heating apparatus with a range hood having an opening for suctioning or exhausting air and a cover for closing the opening, comprising: 
 a heating chamber for accommodating an object to be heated therein;    a heating unit for heating the object to be heated;    a cooling unit for cooling the heating unit;    a microcomputer control unit for controlling the heating unit and an automatic opening/closing operation of the cover;    a control panel for setting an operation of the apparatus;    a display unit for displaying the control status; and    a detecting unit for detecting an exhaust direction of a blower,    wherein the exhaust direction of the blower alternates between indoor circulation and outdoor ventilation and, based on a detection signal from the detecting unit, the control unit opens the cover when the exhaust direction of the blower is set for indoor circulation while the control unit closes the cover when -the exhaust direction of the blower is set for outdoor ventilation.    
   
   
       2 . The apparatus of  claim 1 , wherein the control unit has an option for opening or closing the cover and performs a control for closing the cover only when the exhaust direction of the blower is set for outdoor ventilation.  
   
   
       3 . The apparatus of  claim 1 , wherein the control unit detects the exhaust direction of the blower based on the detection signal from the detecting unit and the display unit displays the exhaust direction of the blower and an open or close status of the cover when the apparatus is initially energized or the blower is operated.  
   
   
       4 . The apparatus of  claim 2 , wherein the control unit detects the exhaust direction of the blower based on the detection signal from the detecting unit and the display unit displays the exhaust direction of the blower and an open or close status of the cover when the apparatus is initially energized or the blower is operated.  
   
   
       5 . The apparatus of  claim 1 , wherein the cooling unit is provided with intake openings through which room air is suctioned into the apparatus and discharge openings through which, after the room air is circulated in the apparatus, thus circulated air is discharged from the apparatus.
