Description

Cooling insulated tank that can work on the sector or with batteries or solar panels.

The UNIQUE or MIXED ELECTRICAL INSULATED CONTAINER or BAC with electric power and solar energy, with a rescue boat option; is designed with an airtight interior to receive products, especially deep-freezing and preserves at their initial temperature without breaking the cold chain even while waiting at the checkout; the time required to transport food at home or during long journeys by vehicle; leisure trips at sea; in the countryside or even as used by sea and mountain professionals. Its interior frame in light iron with piping that passes around the latter will allow the good diffusion of cold gas in the INSULATED BAC all wrapped in polyurethane foam; the refrigerator's cooling system will adapt to it with its cold or hot dimmer; for its energy source, it will have a plug that can be connected to the cigarette lighter of the vehicle or with its integrated transformer adjustable to 12V or 220V to 240V sector to a house socket NB: it will be necessary to provide a socket waiting in the trunk to receive the INSULATED CONTAINER.

The 12V socket to be plugged into the car will be alternated with a transformer integrated into the ISOTHERMAL BAC to allow connection to the 220V or 240V mains; the third method of energy will be solar energy; the break panels on the lid of the BAC and covered with shatterproof glass will guarantee high reliability as well as the energy storage batteries will allow constant autonomy and in any place a good functioning of the electrical system, thus even during queues at the cash desks, the ISOTHERMAL BAC will always be on thanks to this energy storage method; they will be partly mounted on the ex-towable cover of the INSULATED BAC (the solar panels) and below the ISOTHERED BAC (the batteries and the circuit) thus just like the frame will be coated with polyurethane foam, in addition the ISOTHERMAL BAC not equipped with the solar system will be equipped with rechargeable batteries alternating with different other sources of electrical energy such as the domestic or industrial sector (220V; 240V) see the cigarette lighter (12V) this to always allow autonomy in the ISOTHERMAL BAC during all travel; note that this cover is multifunctional as a source of energy for another device that can receive it characteristically Ex: a radio; a camera or even recharge a phone, an electric razor, a rechargeable electric lamp, a small electric inflation pump etc ... The cover can be in a single block as it can be made a two-piece in order to serve the INSULATED BACS MIXED hermetically covering the cold part and the other dry compartment. Note that this cover may have a built-in chip for identification in the event of loss or during an accident and other accessories; in order to be a real rescue or leisure and survival tool for all users who have one. We can add a boat folded under vacuum, self-inflating automatically or inflatable in case of great distress, in which case the dimensions of the BAC ISOTHERME will be resized in order to store the package of the boat under the lid of the BAC ISOTHERME for those who would go to sea (the professionals), or to the countryside with a SINGLE OR MIXED INSULATED TRAY, for their leisure or professional use.

ALL STANDARD MODELS: will comply with the following Specifications; The HEIGHT outside compared to the height of the vehicle trunks (NF) at the same time the height of a supermarket trolley in order to find itself at a good level and at the depth “inside the height of a bottle two liters ”. the outside width of the ISOTHERME BAC will be as wide as a supermarket trolley and inside capable of holding a bottle of two liters in width.

The ex-towable cover will present two options for the INSULATED BAC Single it will be in a single block and for the MIXED ISOTHERM BAC the cover is presented in two stages that on the cold side and the other dry or hot side this system will allow a better vas and comes between the compartments.

The standard ISOTHERME BAC will be equipped for ease of movement on the ground with four castors which can be folded down below the latter towards the inside in order to allow the BAC to be anchored to the supermarket trolley provided for this purpose, now having this BAC ISOTHERMAL we can do these shopping in shops without having to worry about the cold chain and loading in the car.

This INSULATED CONTAINER is provided with two handles adjustable by stops by pressing on a bar; these handles which are on each side of the width of the tank also fit into the frame after use. The maximum adjustment of the handles depends on the depth of the BAC frame.

Below the INSULATED BAC, four fixing points appear to anchor it to the cart provided for this; with a release provided by a handle to the console of the trolley in complete safety. Figure No. l

Reveals in (1) the outer envelope of the container in colored unbreakable rigid plastic; in (2) discover the light piping frame which passes the cold gas around the tank the latter is wrapped in polyurethane foam to insulate the cold well and obtain the maximum temperature, all this will be embedded against the first external tank (1) and by another tank inside (3) waterproof and hermetic in material plastic more flexible than the outside to allow the cold to penetrate inside. The inner tray fits around the periphery of the outer tray to form a single uniform and homogeneous body, the trays can be disengaged to extract the inner tray (3) to respond to any repairs to the cooler cooling circuit. Figure N ° 2

Discover in (4) the two side handles adjustable according to the depth of the tank by a cleat system by pressing on a horizontal bar mounted above the handles. These handles, adjustable by tabs by pulling, lock automatically. By a simple pressure on the upper part of the handle, these handles are stored after use on the sides of the width of the tank by cleverly fitting between the two tanks (1) and (3) figure 1. Figure N ° 3

Shows you in (5) the appearance of the monobloc cover for a single bin, nothing more classic, this retractable cover is hooked to the cooler by the hinges mounted in two parts on the one hand on one of the lengths the cooler and on the other hand on one of the lengths of the cover, all of this is well adjusted by seals, a chip emitting SOS signals, incorporated in the structure of the cover which snaps at will, (5) , (11) and (13) in the context of high-level relief. Figure N ° 4

Discover in (6) and (7) a cover that can be folded down in two stages and retractable to optimize the comings and goings in The MIXED ISOTHERME BACS, this cover clings to the cooler by the hinges mounted in two parts, on the one hand on the 'one of the lengths of the cooler and on the other hand on one of the lengths of the cover all this coming well fits by joints. This tank is separated by an airtight and watertight partition inside with cold side (8) and dry or hot side (9). Figure N ° 5

Appears the monoblock cover (11) with these solar panels (12) fixed on the back of the cover allowing the good functionality of daylight capture to meet the needs of the solar energy system, these panels are protected by shatterproof and waterproof plastic, by a seal to avoid any water infiltration etc ... this window being removable to allow all possible repairs. Depending on the single or mixed container, this cover can can also be folded down in two stages if necessary for the mixed container in Figure 4, whatever the option of the cover, mono-block or foldable in two stages it will be retractable mounted on hinges as previously described, but with in addition contact points magnetic on each part of the hinges, on one side on the cooler itself and the other side on the hinges of the cover. Figure N ° 6

In the option of the self-inflatable or inflatable rescue boat we will see in (13) the cover of the much thicker tank to make room for the embedding of the latter with always the option of the solar system, so having the solar panels on the back of the tank cover for its energy source in figure 5 in (12) or with the electric transformer to be connected to the vehicle or a household supply as the energy source in figure 7 in (14). This two-part cover being made up of two shells, one for the upper side (outside) made of the simple structure or with the solar energy structure incorporated and the other shell for the bottom of the cover (inside side of the cooler) ; between which is embedded the boat, a zipper being used installed around the two parts of the cover inside the upper part and inside the part of the underside of the cover, to close hermetically or open them two parts (shells). This boat will really open at the request of the user by simply operating the zipper. The insulated tank can be single or mixed but with a mono-block cover in the specific case of the self-inflatable or inflatable rescue boat. Figure N ° 7

Below the BAC in the direction of the widths in the angle in (14) we see the place where the transformer is embedded with its outputs for the connection provided either on mains or the cigarette lighter (from 12V-220V-240V), there is also a graduated circular button (the thermostat) regulating cold or hot, the whole being stored and closed by a small door (14) of rounded shape to form the left outside corner of the cooler and the other on the side we see in (15) the storage of the recharge and reserve batteries to store all the energy necessary for the autonomy of the Iso tank both for the solar system and for conventional electric energy there are also the orifices for the electrical connections all this is closed after use for good storage and protection of accessories, by a small door (15) of rounded shape to form the right outside corner of the cooler; in (16) we see the removable casters which fold below the tray in order to fit in their place respectively provided after use, while leaving sufficient apparent thickness on the rollers for when folded serve as feet below the cooler and allow it to be hung on the trolley provided when necessary. All the space remaining below encloses and embeds the motor (17) and accessories for its proper functioning the whole system for operating a small refrigerator; a very rigid, unbreakable, opaque plate sealed with a seal closing the assembly, to form the underside of the insulated cooler, this plate being removable if necessary to reach the mechanisms for all possible repairs. Figure N ° 8
