ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a device for moving the basket of a fryer.
BACKGROUND OF THE INVENTION
Currently known fryers comprise an oil-containing tank for frying the food products that are generally contained in a basket.
The fryer basket may be stationary, i.e. can be manually inserted and removed from the oil tank of the fryer, or mobile, i.e. may be moved inside the tank by means for example by a mechanism activated by the rotation of the basket handle.
In this last case, the motion of the basket can be effected with the lid closing the fryer and therefore with several advantages.
The moving mechanism of the fryer basket is, however, rather complex and, therefore, tends to malfunction in the long run also because of food residues that clog the mechanism.
A further consequence of the complexity of the mechanism for moving the fryer basket is its high production cost that results in a high retail cost of the fryer.
Furthermore, the prior art mechanisms used to move the basket up and down in the tank also involve movements along different directions that may lead the basket to rub the walls of the tank.
This continuous rubbing eventually leads to scratching of the basket and/or tank surface which may be constituted by an anti-adherent material.
The scratching also causes particles of unwanted material to fall into the cooking oil.
OBJECTS OF THE INVENTION
It is an object of the present to eliminate the above described inconveniences of the cited prior art.
An important object of the invention is to provide a device for moving the basket of a fryer limiting such operation to movement only along one direction.
A further object of the invention is to provide a device for moving the basket of a fryer which is extremely simple and effective in order to ensure a long life of the device at least as long as the life of the fryer.
A further object of the invention is to provide a device for moving the basket of a fryer that prevents any scratching of the basket against the tank surfaces thus preventing any damage to the tank and to its anti-adherent lining that may generate particles of unwanted material that may pollute the cooking oil.
Still a further object of the invention is to provide a device for moving the basket of a fryer such that the motion of the basket is always guided and controlled by the rotation of the basket handle.
SUMMARY OF THE INVENTION
The above and other objects that will be more apparent hereinafter, are achieved by a device for moving the basket of a fryer comprising a support body having hinged therein on a first side a bow member engaging with its ends the fryer basket, and on a second side a handle of said basket engaging said bow member, said device further comprising a basket guide means for transforming a rotary motion of said handle and of said bow member about their respective axes of hinging to said support body, into a translatory motion of said basket inside said fryer.
Further characteristics and advantages of the invention will be more apparent by the following description of an embodiment of the invention, illustrated, by way of example in the enclosed drawing.
