Induction range including an air layer for improving heat resistance and shock resistance

Abstract

Disclosed is an induction heating range with improved thermal resistance and impact resistance and, more particularly, to an induction heating range, which can prevent electronic devices inside the heating range from being damaged or malfunctioning due to heat transferred into the heating range from a heating target that receives heat in use of the induction heating range, thereby improving thermal resistance and impact resistance.

1 . An induction heating range having improved thermal resistance and impact resistance, comprising:
 an upper body including an upper plate exposed outside to provide a seating surface for a heating target to be heated by electromagnetic induction, a lower plate separated from the upper plate, and a support protrusion interposed between the upper plate and the lower plate, the upper body having an air layer formed by the upper and lower plates and the support protrusion to block heat transfer; and   a lower body including a housing supporting a lower side of the upper body, a coil formed inside the housing and generating an electromagnetic field upon application of voltage to the coil, and a controller controlling generation of the electromagnetic field in the coil.   
     
     
         2 . The induction heating range according to  claim 1 , wherein the upper plate comprises a horizontal guide piece horizontally extending from the upper plate to guide heat transferred to the air layer, and the lower plate comprises a vertical guide piece separated downwards from the horizontal guide piece and vertically extending upwards from the lower plate. 
     
     
         3 . The induction heating range according to  claim 2 , wherein a space between the upper plate and the lower plate serves as a flow channel of air in the air layer. 
     
     
         4 . The induction heating range according to  claim 2 , wherein the horizontal guide piece is curved upward to allow smooth discharge of heat transferred to the air layer. 
     
     
         5 . The induction heating range according to  claim 4 , wherein the horizontal guide piece covers the vertical guide piece while being spaced above the vertical guide piece to prevent foreign matter from entering the space between the horizontal guide piece and the vertical guide piece. 
     
     
         6 . The induction heating range according to  claim 1 , wherein the air layer has a thickness of 0.8 mm to 1.2 mm. 
     
     
         7 . The induction heating range according to  claim 1 , wherein the support protrusion is formed on a lower side the upper plate or on an upper side of the lower plate. 
     
     
         8 . The induction heating range according to  claim 1 , wherein the lower body further comprises a cooling fan placed inside the lower body to discharge heat from the lower body, a heat sink placed on the controller and dissipating heat from the controller, and an outlet through which heat of the lower body is discharged. 
     
     
         9 . The induction heating range according to  claim 1 , wherein the upper plate is formed at a lower side thereof with a coupling groove coupled to the support protrusion to secure the upper plate and the support protrusion. 
     
     
         10 . The induction heating range according to  claim 1 , wherein the upper plate and the lower plate are formed of a heat-resistant plastic or tempered glass having a thickness of 2 mm to 4 mm.
