Description


   <Desc / Clms Page number 1>
 



  Electric fryer with the "cold zone" principle.



  This invention relates to an electric fryer with the "cold zone" principle, which includes a tub and an electric immersion resistance located in this tub at a distance from the bottom.



  The products to be fried, for example sliced potatoes, which are introduced into the fryer in a basket, contain a quantity of water which at least partially evaporates, both during pre-frying and through frying.



  During pre-baking as well as during baking, up to 50% of the water evaporates and part of the water will be released into the oil.



  Due to its greater specific gravity than that of oil, this water will sink and collect at the bottom of the cold zone. There, the water can grow into relatively large drops which, when the temperature during frying rises in the cold zone, (although its name suggests otherwise) to a value of even 160oC, are transformed into steam.



  In particular when the temperature in the cold zone rises above 130 ° C, the steam mass will suddenly rise through the oil with a kind of explosion, with a force that can cause the oil to splash up to 100 cm high.

 <Desc / Clms Page number 2>

 



  These explosions of the steam mass bring with it a frightening sound.



  These explosions cause the fryer to shake and may cause the frying oil to overflow, foam or splash, which is dangerous for the user.



  The aforementioned problems arise with fryers of the aforementioned kind without a lid as well as with fryers with filter lid, but with fryers with filter lid this problem can be even greater.



  With the latter fryers, with the lid closed, the vapor can only partially pass through the filter in the lid.



  It was found that water droplets condense against the lid and fall into the frying oil so that in this case even more water can collect in the cold zone.



  The invention has for its object to realize a deep-fryer of the above-mentioned type which does not exhibit these disadvantages and wherein strong explosions of water falling into the cold zone are avoided.



  This object is achieved according to the invention in that, under the electrical immersion resistance, a net is arranged which extends almost to the walls of the tub.



  Rising water droplets or water vapor are split into smaller fractions through the net, so that their power decreases and therefore less explosion noise and fewer splashes are produced.

 <Desc / Clms Page number 3>

 The openings of the net or the meshes are preferably as small as possible, but they must allow water to pass through.



  The net preferably has meshes which are smaller than 4 mm 2 and even more preferably are situated between substantially 2.5 mm 2 and substantially 1.2 mm 2.



  It has been found that a net with square meshes of substantially 1.5 mm x 1.5 mm to 0.5 mm x 0.5 mm is very suitable, but the meshes can also have shapes other than a square.



  The net can be fixed to the tub, but this net is preferably removable.



  The net can rest on an inward-facing shoulder formed by the tub.



  The net may consist of a mesh with the aforementioned meshes and a frame to which the mesh is attached.



  This net can contain a circumferential frame on the circumference of the mesh with which it can rest on the aforementioned shoulder formed by the tub.



  The net can have a floor in its middle. The upwardly extending peripheral edge of this recess can connect at the top to a strip which is fixed on the top of the peripheral frame so that a receiving space is formed under this strip.

 <Desc / Clms Page number 4>

 



  With the insight to better demonstrate the characteristics of the invention, a preferred embodiment of a fryer according to the invention is described below as an example without any limiting character with reference to the accompanying drawings, in which:
Figure 1 shows a perspective view of a fryer according to the invention, with partial cutting away of the tub;
Figure 2 represents a section along the line 11-11 in Figure 1, drawn to a smaller scale;
Figure 3 shows on a larger scale the part which is indicated by F3 in Figure 2.



  The electric fryer with the "cold zone" principle shown in the figures consists essentially of a tub 1, a removable electric immersion resistor 2 disposed therein at a distance from the bottom, a filter cover 3 and a net 4.



  In the example shown, the tub 1 is a metal inner tub that is still surrounded by an outer tub or casing 5.



  Connected to the casing 5 is a control box 6 in which a connection of the power supply to the immersion resistor 2, a power switch and the switching part of a thermostat are located and on which a control button 7 for switching on the fryer and selecting the temperature for frying is applied.

 <Desc / Clms Page number 5>

 The filter cover 3 can be hinged to the jacket 5 or the control box 6. In a variant, the filter cover can be a loose cover that is simply placed on the tub 1 and the jacket 5.



  The filter cover 3 contains in its center a filter 8, which can for instance be an active carbon filter but can also be a permanent filter or any other filter.



  In yet another variant, the filter cover 3 may be omitted.



  As shown in Figs. 1 and 2, the immersion resistor 2 comprises a portion 2A which forms the actual resistance and describes a loop parallel to the bottom of the tub 1 and a connecting portion 2B which extends upward from a ends of said loop along a side wall of the tub extends and penetrates into the control box 6. In the example shown, this connection part 2B is bent and penetrates into the control box 6 through a two-part seal 9 which is arranged in a recess 10 in the upper edge of the tub 1, but it is clear that the connection part 12B also in other ways can penetrate control box 6.



  The net 4 consists of a metal mesh 11 which is fixed with its edges in a metal frame 12.



  The metal mesh 11 can consist of woven wire or stretched metal, this is a plate made of incisions

 <Desc / Clms Page number 6>

 was provided and stretched so that the incisions are turned into openings. The metal mesh 11 can be made, for example, from stainless steel or from tinned or nickel-plated steel.



  The metal mesh 11 has meshes with an area smaller than 4 mm 2 and is preferably between 2, 5 and 0, 2 mm 2.



  The meshes can be square with dimensions of 2 mm on 2 mm and preferably between 1.5 mm on 1, 5 mm and 0.5 mm on 0.5 mm, but it is clear that they can also have other shapes and for example can be rectangular, diamond-shaped and the like.



  The frame 12 comprises a frame 13 around the mesh 11 and a support beam 14 welded on top of this frame 13 on which the part 2A of the immersion resistance 2 is supported, as can be seen in detail in Figure 3.



  The net 4 fits substantially against the wall of the tub 1 and for this purpose the frame 12 with the frame 13 is resting loosely on an inwardly directed shoulder 15 which is formed at the bottom by a narrowing of the tub 1. The net 4 is therefore removable from the tub 1.



  The metal mesh 11 has a recess 16 in its center which, with its circumferentially rising peripheral edge at the top, connects to a wide horizontal strip 17 which is welded on the outside to the top of the frame 13.

 <Desc / Clms Page number 7>

 Between this frame 13 and the oblique peripheral edge of the recess 16, the net 4 forms a sort of collection hood so that a collection space 18 is formed under the strip 17.



  This collection cap prevents the frame 13 from escaping everywhere against the shoulder 15, rising bubbles between the shoulder 15 and the frame 13 escaping along the wall of the tub 1.



  Bubbles are collected in the collecting space 18 and rise from the latter through the part of metal mesh 11 that defines this collecting space 18 and are thus divided into smaller harmless bubbles.



  The bottom of the recess 16 is preferably at a distance of approximately 12.5 mm from the tub bottom.



  In the embodiment shown, the frame 12 comprises brackets 19 welded to this frame 13 and which lie over the part 2A of the immersion resistor 2, so that the net 4 is taken out when the immersion resistor 2 is removed.



  It is clear that any leftovers from it too. deep-frying bakeware falling into the cold zone through the net 4 will be stopped. When removing the net 4, these leftovers are removed and the frying oil is filtered.



  However, the most important function of the net 4 is not the filtering but the fact that the net 4 is out of the cold zone

 <Desc / Clms Page number 8>

 divides rising bubbles of water and water vapor into small harmless bubbles.



  The smaller the meshes of the net 4, the smaller the small bubbles, but the meshes must be large enough to allow water falling in the oil to pass through.



  By dividing the large steam bubbles into smaller steam bubbles, large "explosions" are avoided, thereby avoiding strong explosion noises and avoiding the splashing of the oil and thus the foaming of oil over the tub 1.



  The frying is therefore very quiet and safe.



  The invention is of course not only applicable to deep-frying potato pieces, but also to deep-frying other baked goods that bring water into the frying oil.



  The net 4 does not necessarily have to consist of a mesh 11 and a frame 12. It can be strong enough per se to be used without a frame 12. If a frame 12 is present, then this does not necessarily have to have brackets 16.



  The invention is in no way limited to the embodiment described above and shown in the figures, but such a deep fryer can be realized in various variants without departing from the scope of the invention.
