Stone-lining for oven

Abstract

A lining construction ( 10 ) for an oven ( 40 ), has a top panel ( 11 ), a base panel ( 12 ), a rear panel ( 13 ), a left side panel ( 14 ) and a right side panel ( 15 ), constructed from a stone material, such as engineered stone. The top panel ( 11 ), base panel ( 12 ), rear panel ( 13 ), left side panel ( 14 ) and right side panel ( 15 ) are supported on a structural framework ( 16 ) to form a lining cassette ( 20 ). The lining cassette ( 20 ) can then be engaged with and secured in a housing ( 32 ) of a range cooker ( 30 ), via mounting brackets ( 21 ). A single modular construction of lining cassette ( 20 ) can be combined with different sizes and configurations of housing ( 32 ) to provide an array of range cookers ( 30 ) with different configurations and numbers of ovens ( 40 ).

1 . A lining construction for an oven, said lining construction comprising a top panel, a base panel, a rear panel, and left and right side panels, wherein at least two of said panels are constructed from a stone material. 
     
     
         2 . The lining construction as claimed in  claim 1 , wherein all of said panels are constructed from a stone material. 
     
     
         3 . The lining construction as claimed in  claim 1 , wherein the stone material is engineered stone. 
     
     
         4 . The lining construction as claimed in  claim 1 , wherein the stone panels have a thickness of substantially 20 mm. 
     
     
         5 . The lining construction as claimed in  claim 1 , wherein said panels are assembled in a structural framework thereby to form a lining cassette. 
     
     
         6 . The lining construction as claimed in  claim 5 , wherein the structural framework is constructed from steel. 
     
     
         7 . The lining construction as claimed in  claim 5 , wherein the lining cassette further comprises a layer of heat conductive material between the panels and the structural framework. 
     
     
         8 . The lining construction as claimed in  claim 7 , wherein the heat conductive material comprises at least one of graphite and graphene. 
     
     
         9 . An oven having a top panel, a base panel, a rear panel, and left and right side panels, wherein at least two of said panels are constructed from a stone material, and further comprising a door forming a front panel, said door and said panels together defining an oven chamber. 
     
     
         10 . The oven as claimed in  claim 9  having a lining construction, comprising a top panel, a base panel, a rear panel, and left and right side panels, wherein at least two of said panels are constructed from a stone material, and wherein the door and the lining construction together define the oven chamber. 
     
     
         11 . The oven as claimed in  claim 10  having a lining construction wherein said panels are assembled in a structural framework thereby to form a lining cassette, wherein the door and the lining cassette together define the oven chamber. 
     
     
         12 . The oven as claimed in  claim 11 , further comprising high density insulation pads arranged externally of the lining cassette. 
     
     
         13 . The oven as claimed in  claim 9 , being an electric oven. 
     
     
         14 . The oven as claimed in  claim 13 , comprising one or more electric heating elements, arranged such that the panels convey radiant indirect heat from said heating element to the oven chamber. 
     
     
         15 . The oven as claimed in  claim 14 , wherein a said electric heating element is located beneath the base panel. 
     
     
         16 . The oven as claimed in  claim 14 , wherein a said electric heating element is located above the top panel. 
     
     
         17 . A range cooker having one or more ovens, said one or more ovens each having a top panel, a base panel, a rear panel, and left and right side panels, wherein at least two of said panels are constructed from a stone material, and further comprising a door forming a front panel, said door and said panels together defining an oven chamber. 
     
     
         18 . The range cooker as claimed in  claim 17 , having two ovens both heated by the same electric heating element. 
     
     
         19 . The range cooker as claimed in claimed in  claim 17 , further comprising an external housing. 
     
     
         20 . The range cooker as claimed in  claim 19 , wherein at least one of the external housing and/or the door are constructed from steel.
