Definitions
- the present invention deals with a refrigerator operating with a battery with wide versatility, aimed to contain foodstuff which can require different storage and dispensing temperatures.
- Portable refrigerators are currently known, which are composed of a refrigerating unit, generally supplied with batteries, aimed to transport and dispense foodstuffs. These refrigerators are known, for example, from US-A-3866433 , JP-A-H11-325710 , JP-A-2001-324253 and JP-A-2002-225763 .
- refrigerators According to the type of food which must be delivered, home-made or industrial ice-creams, beverages or other, known refrigerators are designed to keep, for a certain number of hours, an optimum temperature for the transported foodstuff, and are equipped with suitable openings to provide access to the refrigerated container.
- Portable refrigerators are also known, which are simultaneously equipped with openings for containing and dispensing ice and beverages, or also spilled beverages.
- door-type openings is necessary for dispensing industrial ice-creams, but implies a damaging clod dispersion in case of home-made ice-creams, for which it is preferable to use "carapina” (steel containers for preparing ice-creams).
- the obtained advantages consist in the chance of easily changing the type of stored and dispensed food, keeping for each one of them the best storage conditions and anyway guaranteeing a high autonomy.
- a transportable refrigerator comprising an insulated container 1 which can be associated with many interchangeable insulated covers 2, 3, 4 suitable for dispensing different foodstuff.
- interchangeable cover means covers which can be easily replaced manually one with the other, without using specific mechanical tools or other types.
- the insulated covers 2-4 comprise a cover 2 for storing and dispensing loose ice-cream or crushed-ice drinks in carapinas, a door-type cover 3 for storing and dispensing industrial ice-creams or beverages and other foodstuff, and finally a cover 4 for storing and dispensing beer or beverages in drums.
- the internal temperature of the container 1 is taken and kept at the desired values through an electric refrigerating unit 5, preferably composed of a refrigerating unit with vented condensation, operating with direct current, preferably at 24 V, supplied by one or more accumulators 6 capable of autonomously suppy the unit 5.
- an electric refrigerating unit 5 preferably composed of a refrigerating unit with vented condensation, operating with direct current, preferably at 24 V, supplied by one or more accumulators 6 capable of autonomously suppy the unit 5.
- the unit 5 is controlled by electronic control means arranged to detect and keep the internal container temperature at predefined values associated with the type of foodstuff being contained. For example, for a home-made ice-cream -12°C; a packaged industrial ice-cream -18°C; beverages +4°C.
- the container 1 can further comprise one or more separators to define internal compartments having different temperatures.
- the electronic control can comprise different temperature detecting sensors and compartment cooling circuits which are separately controlled.
- the container 1 and the refrigerating unit 5 can be integrated in a single, autonomous body, which can be used in fixed locations 7 and/or on different mobile structures, thereby obtaining a single body without integration onto a means of transport ( Figures 3 and 4 ), or be separate and integrated in the structure of a means of transport 8 ( Figures 5a , 5b , 5c ) being housed in different spaces suitable for maintaining the homologation of the same means.
- Figure 6 schematically shows the electric plant of the refrigerating apparatus.
- Such electric plant substantially comprises: a plug 10 for recharging the accumulators 6; batteries 11, 12 of an AGM type, for supplying the electric plant, connected to the plug 10; a DC airtight compressor 13 connected to the batteries 11, 12; fans 14, 15 for the condenser connected to the compressor 13; a control panel 21 for the electric plant, connected to the compressor 13; a fan 16 placed inside the tank and connected to the panel 21; a LED-type illuminating lamp 17 connected to the panel 21; a control push-button 18 for water delivery connected to the panel 21; a pump 19 for water delivery connected to the panel 21; and a probe 20 for the temperature thermostat of the tank connected to the panel 21.
- Figure 7 shows the device for recharging the accumulators 6 of the refrigerator, which comprises a plug 22 for recharging the accumulators 6; a plug 23 for the electric mains; and a battery-charger 24 connected to both plugs 22 and 23.
- FIG 8 schematically shows the electric refrigerating unit 5, which comprises: a DC airtight compressor 25; a condenser 64 of the lamellar type with forced cooling connected to the compressor 25; a filter 27 for impurities connected to the condenser 64; an expansion valve 28 connected to the filter 27; and an evaporator 29 with internal serpentine for the tank connected to the expansion valve 28 and to the compressor 25.
- the invention obtains important advantages.
- the same refrigerator can be separable from the supporting structure to be assembled without modifications on different means of transport or locations, or be integrated in a means of transport, for example an electric means.
