Description

ELECTRIC FRYER WITH SUBMERGED RESISTANCE WITH A COOLED TANK BOTTOM

The present invention relates to the technical field of so-called oil bath electric fryers, in which food is fried by immersion in a frying bath. The frying bath can be oil, but also melted fat.

The present invention relates more particularly to electric submerged resistance fryers. These devices include an electric heating device arranged in a tank to directly heat the frying bath contained in said tank.

In devices of the aforementioned type, the frying bath has a cold zone extending below the electric heating device. The food present in the frying bath loses water which is evaporated but which can also under certain conditions fall to the bottom of the tank in the form of droplets. These droplets can come together and form a significant volume of water. If during a rise in temperature in the cold zone this volume of water is suddenly vaporized, the transformation of liquid water into water vapor can generate projections of the frying bath outside the tank.

Document WO2018/061307 discloses a forced water cooling type submerged resistance fryer, using water for cooling a tank containing a frying bath. The lower part of the tank is surrounded by a water tank. However, this water tank also surrounds the side walls of the tank over their entire height, and an insulating wall is interposed between the water tank and the side walls of the tank.

These provisions are poorly suited to the creation of an electric fryer intended for domestic or semi-professional use.

An object of the present invention is to provide an electric submerged resistance fryer, in which the phenomena of oil projection can be minimized, and which has an economical construction.

These objects are achieved with an electric fryer comprising a tank designed to contain a frying bath, an electric immersion heating device configured to be immersed in the frying bath contained in the tank, and a water tank, the tank having a tank bottom and an upper rim, the electric immersion heating device having a heating part extending above the tank bottom, the water tank being arranged around and below the tank bottom, the tank of water having a filling opening arranged laterally in relation to the tank, the filling opening being arranged higher than the bottom of the tank, due to the fact that the tank is removably mounted in an outer casing, that the outer casing has the filling opening, and that the water tank is arranged in the outer casing. Thus the tank is independent of the water tank. This arrangement makes it possible to simplify the construction of the electric fryer.

The filling opening may be closer to the heating part than to the upper rim. The water tank aims to cool the lower part of the tank. As the tank is free from the water tank, it is not necessary for the water tank to rise to a significant height. Keeping the filling opening closer to the heating part than to the upper edge of the tank limits the height of the water tank and simplifies the construction of the electric fryer.

The heating part can be closer to the bottom of the tank than the filling opening. In other words, the filling opening can be arranged higher than the heating part. This arrangement makes it possible to obtain a water tank rising higher than the heating part extending above the bottom of the tank.

According to one embodiment, the outer casing has a casing bottom assembled with side walls to form the water tank, the casing bottom extending at a distance from the tank bottom. Thus the water tank is formed by the bottom of the housing and the lower part of the side walls.

The filling opening can then be provided in at least one of the side walls.

The outer casing may have side faces connected by angles. The filling opening can then be made in one of the corners.

According to another embodiment, the outer casing may have a bowl forming the water reservoir and side walls providing the filling opening with the bowl, the bowl being arranged around the bottom of the tank, the bowl extending to distance from the bottom of the tank.

The bowl can then have a free edge partially delimiting the filling opening.

The side walls may extend inside the bowl.

To facilitate filling the water tank, the outer casing may have a viewing window including a lower level indicator and a higher level indicator.

The outer casing may include feet.

The feet can be arranged under the water tank.
