Minibar apparatus and modular pantry Description Field of the art The invention refers to a furnishing element with minibar. More in detail, it refers to a minibar apparatus and modular pantry that allows the mounting, dismounting and the independent use of the single modules. Prior art A minibar is a furnishing component comprising various components, certainly including a pantry, instruments and accessories for preparing various foods and a small-size refrigerator usually used for hotel or commercial use. The minibars can be used for preserving and transporting drinks and small snacks. Provided with small dimensions, they are not adapted to kitchen uses but they are very practical when inserted as part of hotel furnishing. The ease of placement and use that this service ensures for the client has made this an item of common use for all hotels/accommodations. With regard to the refrigerator, there are mainly three types characterized by different refrigeration systems: absorption, thermoelectric, compressor. This useful and compact furnishing component has found multiple uses over the years, with different forms; several examples thereof are described below. One example is the object of the patent application US10731915B2 by T.A. GILLETTE, D.M. KOBOS and T. TUNZI. The invention refers to a system of autonomous pantry containers for insertion on a refrigerator apparatus. A system of pantry containers for a refrigerator apparatus comprises an upright of the pantry having an internal space defined therein, a wall of the pantry that is extended perpendicular to the upright of the pantry, a base positioned substantially parallel to the upright of the pantry. The upright of the pantry, the wall of the pantry and the base define an insertable pantry space having an internal pantry volume. One drawer of the pantry is in operable communication with the internal volume of the pantry, and is actuatable through an opening of the drawer defined in the wall of the pantry between the open and closed positions. The drawer of the pantry includes an external panel that hides the opening of the drawer when it is in closed position. A cooling system is configured for providing cooling to the compartment of the pantry insertable from an external position, this also includes a control that independently manages the temperature of the pantry of the compartment and of the other containers. Another example is the object of the patent application US10006693B2 by CA.J. RAMM, M.S. RICHARDS, R. WADKE and J.J. WITTES. The invention refers to a modular household appliance system for the integration of a pantry space within a household appliance. A refrigeration apparatus comprises an internal volume divided by a median wall into refrigeration and freezing compartments. A false horizontal upright is extended through one of the spaces, parallel to the median wall in order to define pantry space in thermal communication with at least one of the refrigerator and freezer spaces. A central vertical upright is removably engaged with the central wall and divides the compartment of the pantry into a first and second sub-compartment of the pantry. The guides of the first and second external drawer are positioned on the structure of the cabinet within the pantry space and the opposite guides of the first and second internal drawer vertical central upright. The first internal and external guides of the drawer partially define the first sub-compartment of the pantry. The second internal drawer and the second external drawer partially define the second sub-compartment pantry. Another example is the object of the patent application US20040055313A1 by J. NAVEDO and J. BOEING. The invention refers to a portable isolated container with refrigeration. The invention has an insulated container that uses Stirling cooling technology. The insulated container and the Stirling refrigerator include a portable power source, such as a battery, a fuel cell or a solar panel. The Stirling cooling device can supply cooling within the insulated container, for example by means of a heat dissipator and a fan, directed connection to a covering in the insulated container or heat tube connected to the heat acceptor for the Stirling cooling device and routed through the insulated container. Controls can be provided that regulate the cycle of the Stirling refrigerator so to be able to control the internal temperature of the insulated container. One embodiment includes both a freezer portion and a refrigeration portion. The inventions illustrated up to now merely as a non-limiting example, together with the inventions present on the market, have a great variety of possible configurations of pantries, minibars and equipped furniture elements. The object of the present patent is to meet the needs of having a single furnishing element capable of satisfying requests of various kind linked to a minibar service of small, medium and large size, and which is compact but still complete and easily openable, reclosable and movable. Still more advantageously, the service allows the easy movement of the single modules in several embodiments thereof, it provides alternative power supply sources, and it is arranged for the implementation of digital technologies for audio and video assistance facilitated by the possibility of implementing web connection by means of Wi-Fi and Bluetooth technology. Description of the invention According to the present invention, a minibar apparatus and modular pantry are attained. The minibar apparatus and modular pantry offers a food service that is compact but complete, and easily openable, reclosable and movable. The apparatus at its interior has at least a refrigerator, at least a pantry space and at least a removable tray, all variable in number and shape depending on the preferred embodiment. The main housing casing, to which at least an openable and closeable wing is connected, houses the various components, comprises a lighting system with adjustable strip LEDs and mounts a series of retaining means, each on each module pantry and/or refrigerator which have the function of preventing foods from falling during the movement of the apparatus. The refrigerator is also provided with a temperature sensor that can be analog and/or use a display that indicates the internal temperature thereof and allows the adjustment thereof through an analog and/or digital instrument. The apparatus, in one embodiment thereof, is arranged for implementing a digital technical system including a display inserted in the reception casing, at least a digital library, through which one accesses the various cocktails, their ingredients, and the respective preparation modes. The digital library is thus accessible by means of a web portal and/or an application, through which it is also possible, in one embodiment, to access the temperature sensor of the refrigerator and the battery thereof. The refrigerator, in fact, like the pantry modules, in another embodiment are arranged in order to be removable and transportable, being equipped with a set of wheels that are suitable hidden in order to maintain an intended design. In this embodiment, the refrigerator mounts a battery and/or a solar panel in order to ensure alternative power supply sources. Finally, the reception casing, also considering the movement of the loads, is provided with suitable ballasts/weights that ensure the stability thereof. Indeed the apparatus is suited for use as a fixed furnishing element in the case of room use, but it is also possible to extract all its modules from the reception casing in order to place them in the internal and/or external environment, in case of need as for big events.
