Description

FAST FOOD HEATER UNIT INTERFACEABLE WITH IN SITU

EQUIPMENT FOR DISTRIBUTION OF FAST FOOD AND SYSTEM FOR

ADMINISTRATION OF HOT FAST FOOD

[0001.] The present embodiment regards a fast food warmer unit, able to interface with at least an apparatus for the distribution of fast food, where is first manually taken the selected fast food and after acquisition of the information about the fast food taken, introduced inside an oven of the fast food warmer unit.

Application's field

[0002] In the following description, the term fast food, an expression which translates literally as "quick food", indicates a category of food quick to prepare and consume, consisting of a kitchen that is mainly made up of sandwiches, cakes, dumplings, croissants, hot dogs, sandwiches, pizzas, but also derived from other foods and generally classified as fast bakery products filled or not. The goodness of a sandwich, for example, depends not only on the intrinsic quality of ingredients, how it could be the bread, or at our latitudes, the sliced meat or the vegetables in it, but also the fragrance of the food. Touch and smell, are changing, you know, and there is nothing better for your palate to enjoy a sandwich or other fast food warm rather than cold, especially in those cases where, usually, we find ourselves in transit, being able to only allow for brief and impromptu stops. That is to say in brief, how it's certainly more appreciated and certainly of improvement the service that includes the ability to deliver a hot fast food. [0003] The sale and supply of food and not by means of a vending machine is nowadays identified with the term of vending. In enterprises, in places frequented by a large number of public, such as railway stations, airports and so on, using the conventional vending machines, are supplied products that by the larger quantities are hot drinks and cold drinks. In recent years however, there has been a discreet increase in consumption and of the public with the result of a request for a more extensive range of products offered. Vending machines, now very popular, selling fast food and snacks, fresh (stored under modified atmosphere) as sandwiches, sandwiches, cakes, fresh fruit or fruit juice with no preservatives, are everywhere, but one can reasonably assert that there is will to further erode market share even at fast food restaurants such as conventional bars, fast foods, and whatever through hot fast food automatic vending machines. [0004] Under the sale of hot food vending machines, are well known those solutions for the distribution of preserved food. These are apparatuses that work with both chilled and frozen products brought to serving temperature by microwaves inside the distributor. For example, a typical vending machine can include synthetically a storage area of preserved products at low temperature, selective means of pickup of the said products stored at low temperature to be placed inside of a microwave oven, and finally at the end of cooking process, means of delivery the hot meal. One of the most significant parts of this kind of equipment is given by the microwave oven, essentially composed of a cooking chamber within which microwaves are directed through one or more sources of a magnetron. A turntable, which is usually located in a central position behind the cooking chamber, finally has the aim of allowing support, above the facade facing upward, to a container which contains the food or the packaging of food to be administered. [0005] So what can be said is that certainly are known vending machines that furnish hot meals, main and second courses, but also that apparently, to date, are not sufficiently disseminated equipment for the administration of hot fast food, such as sandwiches, cakes and whatever else. On the other hand it would seem a too small inventive step the simple replacement within the known equipment and inside the refrigerator compartment, the hot meal to be administered with fast food, becoming this a trivial design change of the apparatus, but it's not certainly the case for which today is proposed the present embodiment, since it relates to a particular fast food warmer dedicated module and designed to be flanked with existing equipment already in place that ensure the administration of fast food, but cold.

State of the art

[0006] In the field of automatic vending machines of preserved food and of the containers of food for the cooking chamber in a microwave oven, and limitedly to the shape of a microwave cooking chamber, and again in within systems of reading and acquisition of information regarding the products to be administered, a research was carried out which has allowed to show at least the following prior arts:

D1 JP4005792 (Hara) D2 WO20040751 25 (Lupini et al.) D3 US5147068 (Wright) D4 US400471 2 (Pond) D5 CN1 372105 (Sun) D6 DEI Oi l 4022 (Moebius et al.) D7 CN1 601 187 (Piao)

D8 JP2000255648 (Omae)

[0007] D1 is an automatic frozen food dispenser. The purpose is to prevent the heating of goods other than the one it sells, through the insertion of extraneous material, and the operation of a microwave oven without having prior verified whether it's a product sold, and as well its thawing and heating when there is verification that it is an item sold. A user buys the goods from a vending machine nearby, and shall seek a reading device that reads the bar code or magnetic strip joint on goods purchased in order to distinguish the case of goods sold or not. Then it provides to send the signal to a control device. When the goods are verified as actually sold goods, the controller sends a signal to a solenoid, which provides for the issuance of a gate. The user sets the goods in the adjacent microwave apparatus and closes the door. When it presses the start button the microwave oven operates in a state of thaw / heating whose time depends on the type of goods.

[0008] D2 suggests a distributor of hot food. It includes a payment device, a cooling compartment, a device to deliver frozen food, and one or more microwave ovens. Those microwave ovens include a device driver whose operation is regulated on the basis of reading a barcode located on the packaging of the food purchased. [0009] D3 is a vending machine composed of several oven modules, which includes a distribution unit of food in a pack which has a code to control the microwave printed in a predetermined position and which can be read automatically when the packaged product is introduced inside the said oven. The packaging of food has a cylindrical shape and has the code printed along the circumference.

[001 0] D4, similar to D1 , is the combination of an automatic vending machine with a microwave oven. The oven is electrically connected to the vending machine, so to allow the operation of the oven for a predetermined time, only after the food was sold from the adjacent vending machine.

[001 1 ] D5, D6 and D7 propose a microwave oven with a cylindrical shape cooking chamber.

[001 2] D8 is a container for microwave oven. The shape is essentially cylindrical with a circular wall and a bottom, and where on the top there is a lid that closes the container. The cover is provided for a plurality of holes, which are closed in one case by a label adhesive, so that those holes are not completely sealed. The container is of the type that will include frozen products, stored and then cooked through the said microwave oven. When the cooking process is started and pressurized steam is generated within the container, the steam escapes from the said container, lifting the label and going through the said holes in the lid.

[001 3] Also known, is the data matrix code or data matrix, which permits the insertion on a minimal surface a series of machine-readable coded information,. This operation is permitted by the structure of the data matrix code, that compared for instance to an EAN barcode, is bi-dimensional. Ultimately it is reasonable to consider known: a) A microwave equipment distinct from the automatic food vending machine, equipped with a bar code reader device; known as microwave oven apparatus, been it adjacent and interfaced to an automatic food vending machine, where to each food is sealed a bar-code; b) An automatic packaged food vending machine that incorporates one or more externally accessible microwave ovens, a bar code reader device that reads bar codes that contain information about the type of food, package size and the heating time required; c) A cylindrical container, even with lid, for cooking chamber of a microwave oven, where the said container is made of moulded plastic, glass, ceramic or glass-ceramic with holes for the disposal of cooking fumes; d) A microwave oven, with a cylindrical cooking chamber; e) the data matrix code that permits the insertion on a minimal surface a series of coded information, machine-readable; f) the system of administration' of hot foods, consisting for the user in the steps of: i. select the food; ii. make the payment; iii. pick up the packaged frozen food; iv. permit identification of the frozen food by means of codes reading on food packaging by transferring the information related to them to a control device of the microwave oven; v. introduce frozen and packaged food in the microwave.

Drawbacks

[001 5] In the field of microwave ovens, commonly used in automatic vending equipment of fast food or of the devices associated with them, such as in the cases of ovens described D1 , D2, D4, either the shape of the cooking chamber, and the tray or the container of food to be heated, they all present a conformation substantially rectangular or square. This feature, by fact, either for the container that for the conformation of the cooking chamber, or for both, arises a first problem due to the fact that it conditions the content sizing of the said equipment. [001 6] Still, on the shape of the container of food to be heated, we can reasonably say how as a result of the polygonal section of the internal compartment it can not be possible to properly sanitize the container. It's known in fact, that the presence of corners in articles for food, consists an excellent repository of bacteria by preventing proper cleaning treatment as work for routine maintenance. This seems more necessary besides being regulated by specific laws, in the case of automatic equipment for the administration of food, which are usually structured to operate large amounts of food for long periods and often in particular environmental conditions. The same problem is attributable to the conformation of the conventional cooking chamber, because just presents surfaces with many angles, by fact makes problematic the implementation of a radical operation for cleaning, sanitizing and disinfecting in the course of routine maintenance. There is saying that the conformation and configuration of both the cooking chamber and the one of conventional containers so contained in it, does not lend itself to being easily removed.

[001 7] As one of the required functions at the vending machines, is the administration of the classic hot sandwich, there is to say that the general form of rolls of this kind is like a "baguette or loaf of small size, so with an oblong shape. It follows that the use of a traditional container, where the sandwich lies in a lying position, it does not allows a homogeneous heating, offering some surfaces to the heating effect that are more exposed than others.

[001 8] It is also known that the best solution to make uniform heating of foods in microwave ovens is the rotation of the same during the action of microwaves. In known solutions, then, and where applicable, the container regardless of the form, simply rests on the turntable, and it is only and solely with its own weight, as well as the defining walls of the cooking chamber, that is allowed the container to rotate its content. Indeed, it may happen that due to interdependent phenomena such as light weight, greasy surfaces, and so on the container does not rotate as much as the turntable, or it rotates of a relative motion not consistent with that of the turntable. This arrangement involves a non-uniform cooking, non homogeneous, to the detriment of the organoleptic characteristics and quality of food so administered. D3 seems to be the only novelty in their Figure 3 that suggests a cooking chamber of cylindrical section, however, integrated into a more complex distribution device of food stored, but it seems a solution that does not allows the rotation of the food to be heated with the result of obtaining unevenly heating and at excessively long times. [001 9] Solutions D1 and D4 is proposed to combine to the vending equipment an apparatus heating fast food with only one module of microwave oven that can interface with a corresponding adjacent vending machine. It is reasonable to assume that, in this case, the microwave oven modules are specifically dedicated to the type of fast food to be heated, therefore specifically designed for each model of vending distribution. Needless to say when its supposed their replacement or adjustment in accordance with changing tastes of customers, it would require further and significant development time to be adapted to new types and forms of heated fast food. Also making available a single oven to heat the food, does not meet the contextual needs of multiple users or multiple needs of an individual user who wants to taste more of a hot fast food . In this case the solution proposed by D2 D3 as well, would satisfy this requirement, however, the provision of more oven modules provided in this case is linked to a complex unit in that it is a feature offered by a single device that includes integrated the vending machine and the oven. In other words, the known solutions are not offering the ability to interface to a conventional distributor unit of fast food that through an additional unit fast food heater that through several ovens will be able to meet multiple needs related to an individual or a multi-user. Furthermore, the configuration of D2 as well as D3 puts the problem of D4 and D1 in relation to the fact that the oven modules being provided in the integrated complex equipment, are designed specifically for each single model of the vending machine and then if possible, would require, as already noted, another significant development time to be adapted to new types and forms of heated fast food. [0020] In solutions from DI to D4 is mentioned a scanner for reading bar codes, both outside and inside the cooking chamber. The barcode mono- dimensional, conventionally used over the wrapper food, contains a limited number of factual information and this places limits on the use of a dedicated oven, in particular with reference to the function of the specific program of cooking or recipe , which is known to vary depending on the selected and introduced fast food in the microwave. Similarly, this fact imposes limits on the selection and management of the type of packaging and wrapping in particular. [0021 ] Another drawback is that in microwave ovens, especially those of the type likely to use two magnetrons, it is not possible to detect any loss of power, which results in an partial heating at least ineffective for fast food. In other words, bad or good functioning of the oven, for example the fact that only one of the two magnetrons is active, is detectable only by the intervention of the service man, which can eventually find the problem. [0022] From all the above , there is a need for businesses, particularly in the sector, to identify alternative solutions, more effective solutions than hitherto in place. One purpose of this is also to overcome the disadvantages outlined.

Brief description of the embodiment [0023] This and other aims are achieved with this according to the characteristics found in the attached claims, solving the problems exposed by fast food warmer unit interfaced with a device in situ for the distribution of fast food; that unit consists of a structure to contain at least one microwave oven module and a scanner for reading a date code matrix on the packaging of fast food, and in which the cooking chamber of the microwave oven module that has a circular conformation is accessible through a front cover with inside a removable cylindrical container comprises a circular base and a circular section wall, the said wall perpendicular to the said base, in which in correspondence with the wall are made holes that communicate the interior of the container with the external environment, the said base, presents a coupling seats which is jigged with respect to a male portion rotating as an engagement key that protrudes from the bottom of the cooking chamber, so as to make it one the base of the container with the male rotating portion. A sensor is capable to detect the power generated by the magnetron inside the cooking chamber, so as to cause a warning signal visible on the display apparatus and intervene on the logical drive module of the microwave oven so to compensate the power reduction with an increased heating time of the fast food. The delivery system of hot foods, consisting for the user to select the fast food, to make a payment or vice versa, take the food stored and packaged by the vending machine next to the microwave module, allowing the identification of fast food by reading the data matrix code printed on the packaging of the food transferring the information relating thereto to a controller of a microwave oven, place the stored and packaged food in the microwave oven, manually close the hatch that defines access to the cooking chamber of the microwave oven and wait for the said hatch to release.

Aims

[0024] In such way, through the considerable creative contribution whose effect has allowed to reach a considerable technical progress, certain aims and advantages are achieved. [0025] A first aim of the object of the present embodiment was to maximize the area available to the cooking chamber in the microwave oven, thus containing the total size of the microwave oven module and of the unit heating fast food. Moreover, thanks to the conformation of the cylindrical container in the cooking chamber, has been significantly increased the ability of its sanitation, particularly avoiding areas of difficult access, such as corners, which, in the cooking chamber can create a receptacle for dirt and proliferation of bacteria.

[0026] A second aim was to make more uniform heating of fast food in a microwave oven equipped with a device capable of determining the rotation of the same during the action of microwaves. Indeed, it is not known a rotating cylindrical container, cleanable in a periodic way and characterized by an extremely simple coupling mechanism of rotation, in other words to a turntable, which can be conveniently provided at the bottom of each microwave oven module corresponding to the fast food heater unit interfaced to the common equipment for the automatic vending of preserved fast food . [0027] A third aim is to propose a cylindrical container especially for the needs of microwave oven modules designed to quickly heat bread rolls and fast food and similar, which are generally dispensed from vending machines and vending separate from the fast food heater units. In this way the cylindrical container can be removed quickly from the place of rotation provided in the bottom of the cylindrical cavity of the microwave heating system to allow the immediate replacement of the cylinder in order to provide a replacement with an equal cylindrical container, which was sanitized and sealed to replace the one used during previous maintenance of the unit fast food warmer mentioned above. In this manner it's ensured a higher and constant hygiene, especially with regard to the microwave heating section.

[0028] Also in reference to the cylindrical shape of the container, it also guarantees the containment of any liquid and semi-solids that may contaminate other vital parts of the microwave heating system and cause malfunctions of various types. Regarding the presence of holes drilled in the wall, the provision of these allows the escape of cooking steam, a circumstance facilitated by the presence of holes in correspondence of any eventual cover that closes the mouth of the cylindrical container. [0029] The prediction of a sensor capable of detecting power generated by the magnetron inside the cooking chamber, which communicates with the logical unit that controls the oven, always allow to have an optimum heating of fast food, as well as facilitating service by the maintainer. Again, the use of a data matrix code on the packaging of fast food to be heated, can implement a significant information acquired from the logic unit that controls the fast food heater unit, which data processing allows the management of a rational and economic system fast food heater. [0030] Ultimately, we made it possible to obtain a fast food heater unit with at least a microwave oven module, which offers the possibility to combine, in one structure of containment, more module of the oven, in vertical or series, implementing the capacity of rapid and multiple heating of the fast food dispensed even by a single master distributor, with a good technology contents, reproducible at affordable costs. These and other advantages will appear from the subsequent detailed description of preferential solutions of realization with the help of the attached schematic drawings, whose execution details are not intended as exhaustive but only illustrative.

Example of realization of the embodiment

[0031 ] A fast food automatic vending machine (10), such as fresh fast food, chilled, frozen or deep-frozen and held in modified atmosphere wrappers capable of being heated by microwave, is made in one case, a machine body (100) comprising a system for selection and payment for the provision of fast food (1 10) for the allocation of fast food, typically a spiral or augers dispenser, a refrigerator group or cooler that exposes the products through in a refrigerated display window (1 20), a system of supply and manual withdrawal of fast food through a fast food delivery tray (1 30) (Figs. 1 , 6). To the fast food automatic vending machine (10) is interfaced to the data link, also wireless, a fast food heater unit (20, 30) that includes at least a microwave oven module (200a, 200b) (Figs. 5, 7 ), each one provided with at least with two magnetrons (201 , 202), a steam / smoke extractor device (203), and a cooking chamber (21 0, 220) in which inside the said cooking chamber (21 0, 220) is introduced concentrically a rotating cylindrical container (300). More specifically, the microwave oven module (200a, 200b) is of the type provided with at least with one sensor, capable to detect the power generated by the magnetrons (201 , 202) inside the cooking chamber. The said sensor is in communication with the logic control unit of the fast food heater unit (20, 30), so as to detect power variations caused by the poor or nonfunctioning of the said magnetrons (201 , 202).

[0032] In Figure 3, a first cooking chamber (210) consists of a semicircular wall (21 1 ) vertical, with' a bottom (21 2), and an upper entrance (21 3). The wall (21 1 ) is substantially open lengthwise and closing through a flip flap (214) that is integral with the bottom (21 2), to which is externally jointed a gearmotor (400) so as to protrude to the internal side of the bottom (21 2) a polygonal rotating key (401 ). The flip flap (214) which is able to be flap opened, is hinged below the structure of the cooking chamber (21 0). From the bottom (212) protrudes toward the cooking chamber (210), the said polygonal rotating key (401 ) which engages the seat coupling jigs (303) of the base (301 ) of the cylindrical rotating container (300). In correspondence of the semicircular wall (21 1 ), from the opposite side of the flip flap (214) are obtained two microwave input windows (21 5) of microwave input, aligned longitudinally and that they do not look at each other, between which is derived an area provided with holes (21 6) for the extraction of smoke and fumes away from the bottom (212) of the cooking chamber (210). Inside the cooking chamber (210), is to be introduced from the top in a removable way and through the upper entrance (213), the said cylindrical container (300) (Fig.2) which is designed to contain the fast food to be heated in the wrapper package. The cylindrical rotating container (300), which is to be placed near the bottom (21 2) of the cooking chamber (210), is made of plastic material and consists of a circular base (301 ), and a circular wall (302) perpendicular respect to the said circular base (301 ). The circular base (301 ), present in correspondence of the coupling interface to the polygonal key (401 ) of the gearmotor (400) that is protruding with respect to the bottom (21 2) of the cooking chamber (210), at least one corresponding base coupling jigs (303) which is of polygonal section being jigged with respect to the protruding portion of the polygonal key (401 ) of the gearmotor (400), and that in the example shown (Fig. Z) consists of a female cross shape seat. In correspondence of the circular wall (302) of the cylindrical rotating container (300), apart from the base (301 ), openings are cut in the form of holes (304), at least in part coincident with the holes (21 6) of the cooking chamber (210 ) which can be placed along the perimeter or distributed locally, which being passing through the thickness of the circular wall (302) put in communication the interior of the cylindrical rotating container (300) with the outside world, in order to allow the extraction of the steam and cooking fumes. [0033] By way of example, the microwave oven module (200a) (Fig. 5) is installed in the fast food heater unit (20) of Figure 1. The fast food heater unit (20) is represented with a single microwave oven module (200a), with the access facing the front, from the same side of exhibition of the fast food from the fast food automatic vending machine (1 0) . The fast food heater unit (20), which can be structured to offer from the same side more microwave oven modules (200a) connected to each other in series or cascade, is also provided for at least a scanner (21 ) .also for each microwave oven module (200a), and an eventual display (22). Access to the cooking chamber (210) is obtained through the hatch hinged flap (214), leaving the space available to introduce within the cylindrical container (300) the fast food to be heated complete of its wrapping.

[0034] In Figure 4, is represented a different solution of the cooking chamber (220), which in this case is integrated into the microwave oven module (200b). More specifically the cooking chamber (220) is configured like as cylinder, with the top part open with an opening entrance (221 ), a wall (222) having a circular cross section, at which are obtained two microwave input windows ( 215) of microwave input longitudinally aligned and that they do not look at each other, between which is derived an area provided with holes (216) for the extraction of smoke and fumes away from the bottom (223) of the cooking chamber (220). Even in such case, in correspondence of the bottom (223) is committed a gearmotor (400), with a passing means over the bottom (223), the shaft to which is attached the engagement key (401 ), and in correspondence at which is to be bound, in a removable way the base (301 ) of the cylindrical rotating container (300), which is to be introduced and removed throughout the entrance (221 ). Unlike the cooking chamber (210), in which the module (200a) is oriented perpendicular with respect to the fast food heater unit (20), the cooking chamber (220) in the fast food heater unit (30) (Fig. 6) can assume an oblique position (Figure 8), so as to provide the entrance (221 ) open in correspondence at the compartment access vane (500) of the module (200b), closed by a sliding guillotine hatch (510) ( Figs. 7, 8). [0035] The microwave oven module (200b), which integrates the oblique cooking chamber (220), is likely to be incorporated into a fast food heater unit (30) (Fig. 6) along with many microwave oven modules (200b) connected in vertical or in series, and that in the representation of Figure 6, are illustrated aligned vertically. The fast food heater unit (30), is interfaced with the automatic distributor of fast food (10), and is of the type provided of at least with one scanner (31 ) that serves each of the three microwave oven modules (200b) and an eventual display (32). Opening the door (510) (Fig. 7) of the access vane (500) to the cooking chamber (220) of the microwave oven module (200b) is obtained by a sliding guillotine hatch (510) (Fig . 8) so as to have prepared the entrance (221 ) of the cooking chamber (220) tilted towards the user. [0036] Operationally, the fast food automatic vending machine (1 0) is loaded with fast food chilled, frozen or deep- frozen and held in modified atmosphere wrappers capable of being heated. At each wrap is applied or reproduced a matrix data code, in which are encoded a good part of the information relating to the food administered, for example: type of bread, if sliced or baguette, wholemeal or otherwise, and composition such as cheese, cold cuts, salad, etc., date and place of packaging, expiry date, "recipe" understood as a way of heating food that consider a cycle of treatment with details of time and temperature. Once the user has made the selection of fast food wanted, and made the payment through conventional means, the fast food is delivered through the fast food delivery tray (130) and from there taken to be manually transferred in correspondence of the fast food heater unit (20, 30) which is interfaced with the fast food automatic vending machine (10). The user holding the fast food wrapped, shall sweep the scanner (31 , 21 ), passing over the wrapper, so that the information relating to it are to be acquired from the logic unit that manages the fast food heater unit (20, 30). In this way, at least some of the information appear throughout the eventual display (22, 32) of the fast food heater unit (20, 30) or also directly on the system for selection and payment for the provision of fast food (1 10) of the selection and payment, system which can be of the touch screen type, of the vending machine (10). The logic unit integrates the control device that provides for the management of at least the fast food heater unit (20, 30) and determines a first function of discrimination, which can assess compliance of the wrapped fast food expiry date, processing data regarding a "recipe" to it, with respect to the modality of the heating cycle, such as temperature and time and providing also an indication of which is the microwave oven module (200a, 200b) enabled. If its experienced the reading of data such as a not coherent expiry date, the fast food heater unit (20, 30) is not activated, displaying information on the display (22, 32). Otherwise, once the positive information is received and the data processed, the fast food heater unit (20, 30) provides the release of the flip flap and hatch (214, 510) of the microwave oven module (200a, 200b) enabled, allowing insertion of fast food in its cooking chamber (210, 220). In the case of more microwave oven modules (200a, 200b) present in the fast food heater unit (20, 30), it will be visualised a light signal in correspondence of the microwave oven module (200a, 200b) that is enabled besides highlighting digital information on the display (22, 32), so as to prevent the erroneous detection by the user. Once introduced the fast food in the cooking chamber (210, 220), its provided to manually close the flip flap and hatch (214, 510) which, when pulled to, is locked, and activates by means of a presence sensor the heating cycle in the manner provided. After the heating phase of fast food, a light and / or audible signal even in concomitance with the information display (22, 32), will warn the user, while allowing at the same time the reopening of the flip flap and hatch (214, 510) and the taking the hot fast food. In the case is encounter a malfunctioning of the microwave oven module (200a, 200b) enabled, during the heating phase of fast food, revealed by at least one sensor a power below a certain threshold of power generated by the magnetron ( 201 , 202) inside the cooking chamber (210, 220), the logical drive of the fast food heater unit (20, 30) which also controls the microwave oven module (200a, 200b) enabled will adjust the heating time necessary to compensate for the loss of power highlighting at the same time the problem on the display (22, 32).
