DETAILED DESCRIPTION OF SOME EMBODIMENTS

(7) We shall now refer in detail to the various embodiments of the present invention, of which one or more examples are shown in the attached drawings. Each example is supplied by way of illustration of the invention and shall not be understood as a limitation thereof. For example, the characteristics shown or described insomuch as they are part of one embodiment can be adopted on, or in association with, other embodiments to produce another embodiment. It is understood that the present invention shall include all such modifications and variants.

(8) According to the present description, shown in its entirety only in FIG. 1 and partly in FIGS. 2-4, the invention concerns a cooking apparatus 10 for food products. By cooking apparatus for food products, hereafter, we will refer particularly to a fryer for use in the domestic, professional or semi-professional fields.

(9) It is understood that the cooking apparatus 10 can be any other type of apparatus able to cook food products by heating any type of cooking liquid and/or oil or fat contained inside it, and by means of partial or total immersion of the food product in the liquid.

(10) The cooking apparatus 10 comprises a main body 11, visible in FIG. 1, substantially defining its bulk, made either of a plastic material resistant to high temperatures, for example polypropylene (PP), or polyethylene terephthalate (PET), or a metal alloy.

(11) The main body 11 has a hollow configuration and is open at the top to comprise a containing chamber 12.

(12) The containing chamber 12 can be made of an aluminum alloy, or stainless steel, and can comprise inside it a cooking liquid up to a level that is normally predetermined.

(13) In a particular embodiment, and with reference to FIGS. 2, 3 and 4, the lateral wall of the containing chamber 12, near the bottom 13, has a lateral bevel 14 recessed toward the inside.

(14) In substantial correspondence with the bottom 13, on the lateral wall, substantially at its lower end, there is an aperture 15, advantageously circular, able to promote the exit of the cooking liquid from the chamber 12.

(15) The aperture 15 is defined by a longitudinal axis X.sub.1 which, in the embodiment shown, is substantially parallel to the bottom 13; according to variants not shown, the bottom 13 can also be inclined so as to promote the outflow.

(16) In a position correlated to the aperture 15, the main body 11 comprises an exit element 16 with a mouth 17, tubular in shape and with a circular cross section.

(17) In a variant embodiment, the mouth 17 can be replaced by a simple aperture, for example with a circular shape.

(18) The exit element 16, in this case together with the mouth 17, allows to create a selective connection between the inside of the containing chamber 12 and a suitable device for removing and discharging the cooking liquid.

(19) The longitudinal axis of the mouth 17 is advantageously aligned with the longitudinal axis X.sub.1 of the aperture 15.

(20) The exit element 16 also comprises an automatic command device 18, to selectively close the aperture 15, which can be solid with the mouth 17 and not removable. In this case, the automatic command device 18 is housed inside the mouth 17.

(21) In another embodiment, the automatic command device 18 can be selectively removed from the mouth 17, if this is necessary. In particular, the automatic command device 18 can be removed to possibly clean a filtering element 19 which can be disposed inside the mouth 17, between the aperture 15 of the containing chamber 12 and the automatic command device 18.

(22) When connected to the mouth 17, the longitudinal axis of the automatic command device 18 is aligned with the longitudinal axis of the aperture 15.

(23) The automatic command device 18 is connected to a valve retention element 20, selectively openable and closable; the valve retention element 20 comprises elastic drive means, in this case a return spring 33.

(24) In the closed condition (FIG. 2), together with a gasket 21 which can be the O-ring type, the valve retention element 20 interrupts the passage of the cooking liquid toward the outside of the containing chamber 12, while in the open condition (FIGS. 3 and 4), it allows the cooking liquid to pass through the exit element 16 to exit from the containing chamber 12.

(25) The automatic command device 18 can be made of plastic material, for example polyphenylene sulfide (PPS), or polyethylene terephthalate (PET), or any other material resistant to high temperatures, or a metal material.

(26) The cooking apparatus 10 also comprises a removal device 22 which allows the flow of cooking liquid to be discharged through the exit element 16 to be conveyed to the outside.

(27) The removal device 22 comprises an attachment element 23 and a discharge tube 27.

(28) Both the attachment element 23 and the discharge tube 27 can be advantageously made of plastic material, for example polyphenylene sulfide (PPS), or polyethylene terephthalate (PET), or any other material resistant to high temperatures, or a metal material.

(29) The attachment element 23 is selectively and removably connected, on one side, to the exit element 16, and has a configuration in terms of shape and sizes such that it can be coupled mechanically to the mouth 17 and to the automatic command device 18.

(30) The attachment element 23 has a mainly circular conformation with a longitudinal axis X.sub.2 which, when connected to the exit element 16 (FIGS. 3 and 4), is substantially aligned with the longitudinal axis X.sub.1.

(31) The connection of the attachment element 23 and the exit element 16 provides reciprocal clamping, or exerting a pressure until the mechanical clamping is obtained, or by screwing, with a snap-in or bayonet connection, or any other mean suitable for the purpose.

(32) The attachment element 23, in the part opposite to the connection side to the exit element 16, is removably connected to the discharge tube 27.

(33) The discharge tube 27 has a free external end and an internal end associated with a concave aperture 24 made in the attachment element 23, which functions as a seating for the selective rotation of a shutter element 25.

(34) The attachment element 23 and the concave element 24 are connected by a channel 31.

(35) The attachment element 23 also comprises at least two thrust teeth 30, the function of which will be clarified later.

(36) The shutter element 25 comprises a recess 26 inside which the discharge tube 27 is at least partly housed, which has a circular cross section defined by a longitudinal axis X.sub.3.

(37) The discharge tube 27 can be rotated, with respect to the position defined by the exit element 16, between a first position in which the axis X.sub.3 is substantially aligned with the longitudinal axis X.sub.2 of the attachment element 23, and hence also with the longitudinal axis X.sub.1 of the exit element 16, and a second position in which the longitudinal axis X.sub.3 is angled with respect to the axes X.sub.1 and X.sub.2.

(38) In the first position (FIGS. 3 and 4), the automatic command device 18 acts on the valve retention element 20 to open the passage of the exit element 16 and to allow to discharge the cooking liquid from the containing chamber 12, while in the second position the passage is interrupted, as will be seen hereafter.

(39) The attachment element 23 also comprises, in correspondence with its concave aperture 24, a gasket 21 of the O-ring type.

(40) The attachment element 23 also comprises another two gaskets 21 of the O-ring type, in its cylindrical coupling part to the exit element 16, which perform the function of retaining accidental leakages of cooking liquid. The gaskets 21 also guarantee the hydraulic seal between the removal device 22, which constitutes the removable element, and the exit element 16, which constitutes the fixed part, until the complete closure is ensured of the valve retention element 20.

(41) The removal device 22 also comprises a guide portion 28, which comprises a hollow 29.

(42) In a particular embodiment, the shutter element 25 can selectively rotate, its movement being guided by the guide portion 28. The rotation of the shutter element 25 is by an angle equal to the amplitude of the hollow 29, the walls of which thus substantially perform the guide and end-of-travel functions.

(43) In particular, when the discharge tube 27 is in the position to remove and discharge the cooking liquid from the containing chamber 12 (FIG. 4), the shutter element 25 abuts against a lateral wall of the hollow 29, creating a substantial connection of the recess 26 with the channel 31.

(44) In this way the flow of cooking liquid can easily by conveyed toward the discharge tube 27 and then discharged from the containing chamber 12.

(45) The discharge tube 27 also comprises a closing stopper 32 which can be made of elastic material, for example silicone, or a plastic material, for example polypropylene (PP), or polyethylene terephthalate (PET) or polycarbonate, or similar materials resistant to high temperatures.

(46) The closing stopper 32 can comprise another gasket 21, which can be the O-ring type, in order to guarantee the hydraulic seal with the discharge tube 27.

(47) The closing stopper 32 can selectively close the free and open end of the discharge tube 27 to prevent accidental leakages of the cooking liquid during frying and/or operations to discharge the oil and/or during possible movements of or interventions on the cooking apparatus 10.

(48) The closing stopper 32 can be selectively removed from the discharge tube 27 when the discharge tube 27 is in the removal position and the cooking liquid is to be made to flow from the containing chamber 12 toward the outside.

(49) The removal device 22, as we said, is removable from the exit element 16 and can therefore be selectively connected or disconnected to/from it.

(50) In particular, when the removal device 22 is temporarily connected to the exit element 16 (FIGS. 3 and 4), the teeth 30 keep the valve retention element 20 pressed toward the inside of the main body 11, acting against the return spring 33 and determining the momentary opening of the passage of the cooking liquid from the containing chamber 12 toward the outside. In this way, the cooking liquid can be easily removed and discharged, the discharge tube 27 having been correctly positioned (FIG. 4).

(51) When the removal device 22 is removed from the exit element 16 (FIG. 2), for example to clean, maintain or replace it, the retention element 20 automatically moves to the closed position thanks to the action of the spring 33, thus preventing unwanted leakages of the cooking liquid.

(52) The removal of the removal device 22 can also facilitate the transport, storage, packaging, cleaning or washing of the containing chamber 12 or other components of the cooking apparatus 10.

(53) Furthermore, if the discharge tube 27 gets blocked due to food residues, the complete removal of the removal device 22 from the containing chamber 12 facilitates the removal of said residues.

(54) Moreover, the discharge tube 27 too can be dis-associated from the attachment element 23 to promote its cleaning and maintenance.

(55) The presence of the filtering element 19 associated with the exit element 16, in particular with the aperture 15, allows to filter from the cooking liquid any possible food residues contained inside it.

(56) It is clear that modifications and/or additions of parts may be made to the apparatus 10 for cooking food products as described heretofore, without departing from the field and scope of the present invention.

(57) It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of apparatuses for cooking food products, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
