ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a food processing device, and especially to an electric fryer with an elevating mechanism.
BACKGROUND OF THE INVENTION
The existing fryer, especially the electric fryer, is usually composed of a concave pot, and its food basket is normally lifted up manually after the food therein has been cooked. Moreover, the basket cannot be removed until the oil has been drained. Therefore, the cooking efficiency is rather low.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an electric fryer with an elevating mechanism, which is capable of lifting or lowering the food basket automatically, thus realizing the automation of the frying process.
The electric fryer with an elevating mechanism according to the present invention comprises a housing, a top cover, a fryer body, heating elements, a food basket assembly, a temperature controller, a cutout fuse and a timer, and it is characterized in that said electric fryer also includes an elevating mechanism.
Said elevating mechanism is composed of a hoisting sheave, a cam, limit switches and an electromotor, wherein the cam and the hoisting sheave are sequentially secured on the spindle of the electromotor, which is fixed in the housing, and a limit switch is symmetrically arranged at either side of the spindle. Said food basket assembly consists of a food basket, a first rocker, a second rocker, a supporting rod, a slide hook, a sliding sleeve, an axle and a handle, wherein one end of the first rocker is connected with the food basket and the other end is connected with the supporting rod and the slide hook, whereas one end of the second rocker is connected with the food basket and the other end is connected with the supporting rod. Said food basket is suspended in the fryer body by means of the first and the second rockers, the supporting rod is stationarily connected with the sliding sleeve by a screw, and the handle is connected with the slide hook by the axle.
Since the electric fryer of the present invention comprises the elevating mechanism and the food basket assembly, the food basket may be lifted up and down automatically, so that the frying process is simplified. Therefore, the operation is simple, efficient and convenient, and the oil can be drained automatically, thus reducing the consumption of oil.
