Description

BACKPACK WITH COLD CHAMBER

OBJECT OF THE INVENTION

The present invention relates to a backpack with an integrated light mini fridge.

It comes to solve the problem so far unresolved to be able to bring everything that is needed including fresh food and drinks for a family day, individual excursion, travel to the workplace, study, leisure or meeting, in a really comfortable way.

It is common in canteens or rooms equipped for this purpose to find microwaves and means to heat food in companies, schools and study or work centers, and always the most feasible option for the center to supply beverages and refrigerated food passes through machines Vending to enjoy it. In some centers it is true that there are refrigerators or refrigerators, but still the problem of taking something cold by bus or on the road would not be solved.

The mini-fridge integrated in the backpack object of the present invention consists of a specific compartment for foods that need or want to be kept at a low temperature in a controlled manner, with an evaporator-type refrigeration system with compressor and condenser, all these components being suitable for the reduced space of The backpack to be more compact and lightweight.

The advantages of this invention are the following:

- On the one hand, the ice used in the refrigeration of conventional portable refrigerators is replaced with the consequent saving of weight and space it occupied, in addition to leaving everything wet and having to dispose of waste water.

- With a fully insulated watertight compartment, it allows you to have several spaces in the same backpack or suitcase, so that it does not affect the degree of humidity and temperature of the compartment refrigerated to others containing objects that may deteriorate or be damaged by such conditions.

- As it is a backpack with a personal cold store, it allows the user to store their drinks and food in a safer place than the conventional refrigerator shared by different people in the company, with the problems and mistakes that occur frequently derived from it.

- On the other hand, having a portable refrigerator allows the user to acquire a product that can keep cool all the time, to consume in a time slot in which stores and supermarkets remain closed and do not have the possibility to buy it at that time .

- It is a much cheaper and more profitable option compared to traditional refrigerators that use ice to lower the temperature of the food and beverages they contain, despite the economic cost of the refrigerator itself, the price of ice and The action of having to replace it from time to time considerably increases the cost of this second option.

The industrial application of this invention is within the manufacture of backpacks and transport cases, and refrigerating machines, and more specifically the combination of both.

BACKGROUND OF THE INVENTION

Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related to it.

Thus, document ES0289150A1 refers to a portable liquid cooler, consisting of a cylindrical body formed by two pieces that fit together by means of adjustment studs that pass through lugs or facing flanges of both legs; This cylinder is laterally presenting an opening in which a bushing is provided, through which a crankshaft shaft that rests on ball bearings passes, and which has a control handle attached to its outer terminal. The aforementioned refrigerator Portable does not make any reference about its form or means of transport, however the main invention proposes a backpack variant which contains a compartment or cooling chamber.

ES1066933U describes a thermal bag for transport and / or dispensing of beverages, configured from a container bag comprising hanging and / or drag elements, provided with an upper opening and a lower opening, with conventional closing systems, comprising a part inside, constituting a rigid isothermal body of adequate dimensions to fit approximately inside the container bag, where said isothermal piece incorporates at least one compartment suitable for holding beverages with its own original container, having at its bottom a hole suitable for accommodate a tap configured to fit a mouth of a container. In this case, a thermal bag is described, while the main invention goes beyond and proposes a mini-fridge or cooling system that not only maintains the temperature, but allows it to be chosen and reduced.

ES2510290A1 proposes an autonomous, portable and self-cooling system, applied to the cooling of solids and liquids to be maintained within a certain temperature range. Said system consists of a sealed tank in which a liquefied gas under pressure is stored, one or more evaporation control valves and a filling valve; both valves are connected to the sealed tank; said sealed tank functions as a vaporizer thanks to the action of said or said evaporation control valves, arranged, if they are more than one, in series, controlling the evaporation of the LPG that cools the tank and, thereby, regulating the pressure and the internal temperature in the tank; the control exerted by said valve or evaporation valves is carried out from a temperature or pressure sensor and an electromagnetic, electronic, pneumatic or mechanical actuator. In this document, the described portable refrigerant system does not reflect that it is a part or compartment of a backpack for transport, as the main invention does.

ES2244515T3 refers to a thermal container, especially a refrigerant bag for refrigerated transport of food, substances and / or objects, with an envelope that surrounds a transport chamber, with a sealed opening in the envelope to access the transport chamber and with a manually operated translation device, which is coupled to the housing, at least one through hole has been configured in the housing to accommodate a heat exchange device of an active cooling device, - at least one active cooling device is provided with an active cooling element and a heat exchange device that is housed in the through hole, and - the shell is made to adapt the volume of the transport chamber, of a flexible material, especially folding. In this case, although reference is made to transport means, the invention itself consists entirely of the thermal container, while the main invention describes a backpack, with conventional compartments for use and transport of all types of objects, and one especially that it is refrigerant.

ES0273812U describes a new portable bag, in which regardless of the handles and straps to carry by hand, in a shoulder strap, hanging from the shoulder or back and also regardless of the number and form of departments that contain, including one of them, the largest central, which is made as a portable refrigerator, is characterized by the fact that at the end of two opposite sides of the upper face covered with the body of the bag, two flexible extensions are formed in the form of bands preferably of the same length as the sides at which they are born, the free end of each extension is terminated in an elongated eyelet in which the straight horizontal section of an inverted rigid U-tube and blunt vertices are skewered and parallel, such strung sections and the descending arms parallel to each other. of each "U" they cross each other, two to two, on either side respectively of the body of the bag, joining articulately by the cross point and l the descending ends of which crossed arms on each side of two opposites protrude beyond the lower base of the bag itself, so that the body of the bag hangs from its upper side through the eyelet extensions and the two tubes, in inverted "U" act of easel folded during the transport of the carried bag, either on the back as a backpack, hanging from the shoulder or in a shoulder strap or grabbed by hand by the handles and at the time of putting the bag on the floor the easel is opened with that the upper area of the bag and the flexible extensions are tensioned by operating the scissor seat assembly for the user of the bag hanging from the frame. In the latter case, a portable bag with a complex system of extensions and tubes to be used as a seat is described, however, the main invention consists of a light and compact backpack with a special compartment for cooling.

Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.

DESCRIPTION OF THE INVENTION

The refrigerated chamber backpack object of the present invention is constituted from a conventional backpack, with its corresponding compartments, handles and closures, but which has one of the compartments converted into a refrigerated refrigerator, said refrigerator comprising a refrigeration minisystem composed of evaporator, condenser, compressor and expansion valve.

Said cooling system is powered by a battery that is complemented by a solar panel installed outside the backpack. The battery can be charged either by removing it from the backpack and using an external charger, or with an input socket made outside the backpack that connects directly to the battery via USB cable, miniUSB, microUSB, type C or similar. Said input socket can be found inside a pocket to cover the connector and improve the aesthetics of the backpack.

The evaporator is inside the compartment dedicated to cooling and the rest of the elements together with the battery are located in the bottom of the backpack to give stability to it, except for the condenser that protrudes from one of the sides of the backpack so as not to annoy the user while carrying the backpack and improving its cooling.

The entire compartment or cold room of the backpack is lined with insulating and waterproof material, and thermal layer that helps the heat flow is always made from the inside out.

In a different embodiment, the backpack has a second isothermal compartment, isolated from the cold store, which maintains the temperature of those foods that on the contrary require maintaining their heat.

The shape of the backpack can be like the conventional ones, or incorporate forms and aspects that integrate it and relate to any brand or logo in question that sponsors it or to which it belongs, it can even be customized by engraving and printing images and / or photos .
