Cooking device

Abstract

Door packing ( 35 ) having a base ( 36 ), a first lip ( 37 ), and a second lip ( 38 ) is stretched around periphery of a back surface cover ( 31 ) of a door ( 30 ). When the door ( 30 ) is closed, the second lip ( 38 ) is inserted into a heating chamber ( 22 ), the first lip ( 37 ) pivots in directions of arrows (A) once an extremity of the first lip ( 37 ) comes into contact with a front face panel ( 40 ), and an extremity of the second lip ( 38 ) is then brought into close contact with inner wall surfaces of the heating chamber ( 22 ). Thus both the front face panel ( 40 ) and the inner wall surfaces of the heating chamber ( 22 ) are sealed, so that smoke, steam and the like produced by objects to be heated are reliably prevented from leaking out of the heating chamber ( 22 ). Besides, condensed water is prevented from accumulating in a groove formed on a border between the front face panel ( 40 ) and the first lip ( 37 ) while the front face panel ( 40 ) is sealed by the first lip ( 37 ), and thus the condensed water in the groove is prevented from falling down out of the heating chamber ( 22 ) when the door ( 30 ) is opened.

1 . A cooking device comprising:
 a heating chamber ( 22 ) which has an opening ( 26 ) and in which objects to be heated inserted through the opening ( 26 ) are heated by heat from a heat source,   a door ( 30 ) for opening and closing the opening ( 26 ) of the heating chamber ( 22 ), and   door packing ( 35 ) which is provided in a position on the door ( 30 ) that faces an edge of the opening ( 26 ) of the heating chamber ( 22 ) and which seals at least inner wall surfaces ( 22   a ,  22   b ) of the heating chamber ( 22 ).   
     
     
         2 . The cooking device as claimed in  claim 1 , wherein
 the door packing ( 35 ) is provided at least in a position below a horizontal plane passing through a center of the opening ( 26 ).   
     
     
         3 . The cooking device as claimed in  claim 1 , wherein
 the door packing ( 35 ) includes:   a first sealing part ( 37 ) for sealing a front face panel ( 40 ) around periphery of the opening ( 26 ) of the heating chamber ( 22 ) in conjunction with an operation of closing the opening ( 26 ) by the door ( 30 ), and   a second sealing part ( 38 ,  41 ) for sealing the inner wall surfaces ( 22   a ,  22   b ) of the heating chamber ( 22 ) in conjunction with an operation of sealing the periphery of the opening ( 26 ) by the first sealing part ( 37 ).   
     
     
         4 . The cooking device as claimed in  claim 3 , wherein
 the door packing ( 35 ) seals both the front face panel ( 40 ) around the periphery of the opening ( 26 ) of the heating chamber ( 22 ) and the inner wall surfaces ( 22   a ,  22   b ) of the heating chamber ( 22 ) when the opening ( 26 ) is completely closed by the door ( 30 ).   
     
     
         5 . The cooking device as claimed in  claim 1 , wherein
 a depression ( 43 ) for accumulating condensed water produced in the heating chamber ( 22 ) and preventing the condensed water from flowing out of the heating chamber ( 22 ) upon opening of the door ( 30 ) is provided on a side opposite to the opening ( 26 ) with respect to a position of sealing by the door packing ( 35 ) on the bottom wall surface ( 22   b ) of the heating chamber ( 22 ).
