Deep fryer

Abstract

A deep fryer has an outer housing ( 4 ) closed by a lid ( 14 ) and an immersed type heating element ( 28 ) extending into an oil containing receptacle ( 22 ), the housing having an upper rim at which the lid ( 14 ) is supported, with the underside of the lid ( 14 ) having an upwardly domed shape and the rim formed with a channel ( 44 ) arranged beneath the periphery of the underside of lid ( 14 ) to receive droplets of moisture condensing on the underside of the lid during use, a sensor ( 31 ) being provided which includes a thermal use and temperature sensing element ( 56 ) disposed in a single tubular housing.

1 . A sensor for use in an electrical cooking appliance of the type having an immersed heating element, comprising a temperature sensing element and a thermal fuse disposed within a single outer heat conductive tubular housing.  
   
   
       2 . A sensor according to  claim 1  wherein the tubular housing is closed at its end by a plug of thermally conductive material.  
   
   
       3 . A sensor according to  claim 2  wherein the temperature sensing element is disposed within or adjacent said plug.  
   
   
       4 . A sensor according to  claim 3  wherein the plug is formed with an internal cavity with the sensing element located therein.  
   
   
       5 . A sensor according to  claim 1  wherein the temperature sensing element is a thermistor.  
   
   
       6 . A deep fryer having an immersion type heating element for immersion into a receptacle for containing a cooking medium, wherein a sensor according to  claim 1  is supported adjacent to the heating element.  
   
   
       7 . A deep fryer according to  claim 6  comprising a control unit to which the sensor and heating element are connected and including a solenoid-activated relay switch connected to the heating element, the thermal fuse being connected to the solenoid side of said relay switch.  
   
   
       8 . A deep fryer according to  claim 7  wherein the control unit has a pair of relay switches, the thermal fuse being connected to the solenoid side of both relay switches.
