SEMI-AUTOMATIC FRYING PAN WITH FUME AND SMELL PURIFICATION SYSTEM

Abstract: Semiautomatic deep frier which allows to purify fumes and odours of frying fumes prior to their extraction to the outside, for which it is provided in addition to the required frying elements with a condenser (5) inside which is a stainless steel coil (10) which is connected at its bottom to a collector (8) which collects the water and oils of the fry, for which it is connected to a liquid residue outlet pipe (9) ending in a tank (11), or whichever means of collecting said liquid residues, and in which dry air from condenser (5) is made to pass through carbon filters (12) prior to extraction to the outside through grilles (14).

Description: OBJECT OF THE INVENTION The present invention relates to a semiautomatic deep frier with fume and smell purifiers, that is as its name suggests a deep frier with all tasks semi-automated, and in which prior to extraction of the frying fumes a fume and smell purification takes place. Thus, the present invention can be circumscribed to the field of deep friers in which certain frying functions may be programmed. BACKGROUND OF THE INVENTION As of this moment the applicant is unaware of a semiautomatic deep friers in which a fume and odour purification takes place prior to extraction of the fumes resulting from frying. However, we must mention Spanish patent titled Potato Chip Dispenser with publication number ES 2107367, in which the potato, once peeled, cut and refrigerated is fed by means of a worm gear to a moving trolley placed on an adjustable counterweight balance, passing onto a deep frier with one or two consecutive doses, and falling onto a tray separated by a double worm gear with conical ends in which once the potato is fried it is salted and the desired sauces are added. The frier basically comprises a scoop, a blade driving motor, and a tank. With this patent we wish to point out that the means provided for the action of frying are already known. However, in all deep friers present in the market the fumes are extracted directly to the exterior or are previously passed through a filter. Extraction of frying fumes implies a number of disadvantages, such as requiring a smoke extraction system for the site, with the ensuing pipes leading to the top of the building to prevent problems with neighbours, in addition to the odours and grease which are naturally left in the surroundings. Therefore, the object of the present invention I to solve the aforementioned disadvantages and to provide deep friers already present in the market with the means required to purify fumes and odours resulting from frying, prior to their extraction to the outside. As background, worthy of consideration in relation to the present application, European Patent EP 885583 A is referenced, as regards an air treatment system, specifically applicable to a potato chips or similar, frying pan, which includes an environmental air intake which is made to pass through a filter and mixed with the vapours and fumes caused in the frying pan which passes through screens, to be made to pass through a filtering system before reaching a heat interchanger, at the outlet of which, a mixture of vapours and air is made to pass through a condensation separator in which the liquid part is collected in a tank and the air is made to pass through a filtering system before being sent to the outside. This system proves to be complex since it comprises various stages and numerous components, implying high cost of the machine as well as of its maintenance, and being subjected to possible breakdowns precisely in virtue of the numerous elements and complexity of the machine assembly. DESCRIPTION OF THE INVENTION The invention disclosed for a semiautomatic deep frier with purification of fumes and odours consists of a deep frier which allows to fry any frozen or fresh food not larger than a given size, in which said frier basically comprises an external structure in which the frier itself is housed, as well as other elements required for frying, such as the electrical board or programming panel from which the various programs are accessed and modified, where modification entails altering the frying time of each program. In addition there is the fume condenser, the filter box for the previously condensed fumes, the collector, the residue caisson, etc. The deep frier elements required to obtain the object of the present invention for a semiautomatic deep frier with fume and smell purifiers are the condenser and the filter box. The condenser is a prism shaped elements inside which is a stainless steel coil through which flow all vapours generated during frying, causing their condensation. After these fumes are condensed water and oil are generated, which are collected by a collector pipe placed on the bottom of the condenser, specifically on the lower end of the coil. To said collector is connected a plastic tube which drains the oil to a tank for recovery of liquid residues. The remaining vapour which has not condensed, that is the dry air resulting from the condensation, is passed through two active carbon filters placed in the filter box, so that all odours are extracted which may remain in the frying fumes, and are expelled through a grille placed on the top of the frier, where expelled fumes have been previously purified and all smells removed. DESCRIPTION OF THE DRAWINGS The characteristics of the invention will be understood more clearly in view of the following description, made with reference to the accompanying non-limiting drawings, where for purposes of illustration the most relevant characteristics of the invention are shown. Figure 1 shows the inside of the deep frier outer structure, showing the deep frier itself as well as the other elements. Figure 2 shows the previous figure where the deep frier has been extracted, revealing the condenser and the filter box. Figure 3 shows construction details of both the condenser and the collector pipe, as well as their relative arrangement and connection. Figure 4 shows an enlarged view of the filter box and its connection to the collector. PREFERRED EMBODIMENT OF THE INVENTION Figure 1 shows deep frier (2) inside an outer case, in which is the electrical board or programming panel (1). Also shown are residue caisson (4) and fried product opening (7). In figure 2 deep frier (2) has been extracted, revealing the set of fume condenser (5), filter box (6), collector (8), liquid residue outlet pipe (9), grille (14) for condensed and filtered fumes and extraction tray (3) of deep frier (2). Figure 3 shows an enlarged view of condenser (5) inside which is a stainless steel coil (10), connected on its bottom end through the walls of the condenser to collector (8), which collects condensation vapours and the water and oil remains of the frying fumes, to which collector (8) is connected a liquid residue collection tank or any other receptacle. In turn the other end of the collector (8) is connected to filter box (6). Figure 4 shows the inside of filter box (6), which is provided with clamps (13) for closing the lid of filter box (6). Inside filter box (6) are two carbon filters (12) which filter the dry air resulting from the condensation, and where after passing through filters (12) the fumes are extracted to the outside through grilles (14) located on the top of the frier structure. This description is not extended further in the understanding that any expert in the field can understand the scope of the invention and the advantages derived thereof. The materials, shape, size and arrangement of the elements may vary as long as the scope of the invention a defined by claim 1 is unaltered. The terms used in this memory shall be understood in a wide and non-limiting sense.
