A fryer is provided where an oil fire caused by overheating is accurately and rapidly extinguished and the oil can then be reused after extinguishing the fire. A housing includes a slide cover capable of sliding between a housing position and a shielding position, wherein the housing position is to open an upper face of an oil vat and the slide cover is housed on the side of the housing, and the shielding position is to close the upper face of the oil vat.

ФОРМУЛА ИЗОБРЕТЕНИЯ (CLAIMS)
What is claimed is:
1. A fryer comprising an oil vat filled with oil in an upper part of a housing, heating means for heating the oil in the oil vat, a flexible flat shuttered shielding member for arbitrarily opening/closing an upper face of the oil vat, said shielding member being formed by connecting a plurality of plates in a width direction, said shielding member being housed in a longitudinal direction of a housing position located on at least one side of the housing, whereby said shielding member is slidable and continuously movable in an inward overlapping direction over the face of the oil vat, and a detection switch that interfaces with said shielding member to turn the fryer off when the position of said shielding member closes the upper face of the oil vat.
2. The fryer according to claim 1, wherein said shielding member is capable of sliding between an arbitrary open housing position where said shielding member is housed to open the upper face of the oil vat and a closed shielding position to close the upper face of the oil vat.
3. The fryer according to claim 2, further comprising: a lock member at a partition part for securing and holding said shielding member in place when said shielding member is placed in said closed shielding position.
4. The fryer according to claim 2, wherein once said shielding member is placed in said closed shielding position, air flow will be blocked from said oil vat to extinguish any existing oil fire contained in said oil vat.
