A cooking appliance (100) comprising a housing (10) providing a cooking chamber (12), a cooking mechanism associated with the cooking chamber (12) for cooking food therein, and a peltier unit (20) arranged to alter the temperature of the interior of the cooking chamber (12). The peltier unit (20) comprises a peltier device (30) having first and second metal parts which form a junction therebetween and are associated with the interior and exterior of the cooking chamber (12) respectively. In a cooling mode, the peltier device (30) is operable to, upon the passage of an electrical current across the junction in one direction, absorb heat by the first metal part and liberate heat by the second metal part, such that the interior temperature of the chamber (12) may be lowered to facilitate the storage of perishable food. In a heating mode, the peltier device (30) is operable to, upon the passage of an electrical current across the junction in the reverse direction, absorb heat by the second metal part and liberate heat by the first metal part, such that the interior temperature of the chamber (12) may be raised for the purpose of keeping cooked food warm.
A cooking appliance comprising a housing providing a cooking chamber, a cooking mechanism associated with the cooking chamber for cooking food therein, and a peltier unit arranged to alter the temperature of the interior of the cooking chamber, said peltier unit comprising a peltier device constructed by first and second metal parts which form a junction therebetween and are associated with an interior and exterior of the cooking chamber respectively, whereby the peltier device is operable to, upon the passage of an electrical current across the junction in a first direction, absorb heat by the first metal part and liberate heat by the second metal part such that the temperature within the cooking chamber may be lowered to prevent spoilage of food deposited in the cooking chamber.
