Definitions
- the present invention relates to a device for heating and / or refrigerating and / or maintaining in temperature a receptacle adapted to receive particular food.
- WO 2013/098516 A discloses an autonomous cart for temperature conditioning meal trays.
- the cart is divided vertically into two zones, one cold and the other hot. Trays filled with dishes are slid into the cart horizontally; one half of the trays is thus refrigerated, the other heated.
- the heat generating means and the cold production means used comprise a thermochemical reactor connected to a fluid reservoir by valve means. By opening the valve means, the gas is released from the tank or the liquid contained therein is vaporized. The expansion of the gas or its vaporization generates the production of cold at the reservoir.
- the gas leaving the tank reacts on a reagent contained in the reactor, in a reversible exothermic chemical reaction, thus releasing heat in the thermochemical reactor.
- the opposite reaction is induced: the reagent is regenerated and the product gas replenishes the reservoir under the effect of pressure.
- the device described in the aforementioned document has several disadvantages. We can not modulate the space of the cold zone and the space of the hot zone according to the number of trays to be conditioned.
- the thermochemical system comprising the reactor and the reservoir is integral and irremovable of the carriage; during the regeneration of the reagent, the carriage is therefore unusable.
- the cart is bulky and does not easily access the trays; it can not be used in a buffet, for example, because the food is only visible if you open the cart and pull a tray. even though trays can be removed, the cleaning of the interior of the carriage is difficult because of the presence, including electrical resistors used for the regeneration of the reactors.
- An object of the present invention is to provide a device that solves at least one of the aforementioned drawbacks.
- valve means making it possible to connect said reservoir or said evaporator, with said thermochemical reactor for the production of heat at said reactor, because of said aforementioned exothermic reaction and for the simultaneous production of cold at said reservoir, due to detente and / or evaporation of said fluid;
- At least one receptacle of thermally conductive material which has a first face adapted to receive the food to be heated / refrigerated and a second face opposite to said first face and disposed in contact with said heat generating means or said means of production cold;
- the aforementioned module can produce both hot and cold, and use this heat and cold simultaneously or not.
- the module is used to heat or cool food placed in the receptacle.
- the latter may be a plate or a hollow dish, for example.
- the receptacle made of thermally conductive material is in direct contact with the reactor or the reservoir (and / or the evaporator optionally) allows thermal transfer by conduction and no longer by convection, as is the case in the prior art. supra. Cooling / reheating is faster and requires less energy.
- the fact that the receptacle and / or the reactor is removable (s) of the module facilitates the cleaning of the latter.
- the module has a section of the same dimensions as those of standard meal trays ("Gastronorm" GN1 / 1), a width of 325 mm and a length of 530 mm.
- the elementary module can be mounted in any container adapted to receive meal trays.
- the base module comprises a box made of thermally insulating material which contains the means for producing heat, the cold production means and the thermally insulating element.
- said piece of furniture being at least partially made of thermally insulating material and extending under said base module, said base module is adapted to cooperate with said piece of furniture so as to thermally isolate the internal volume of said piece of furniture situated under said basic module.
- the device of the invention comprises a container inside which said base module can be mounted and said base module is able to cooperate with the interior of said container to separate the inside of said container. in two thermally insulated areas.
- the base module may comprise at least two stops, said piece of furniture or said container may comprise support means and said abutments and said support means are respectively disposed on said base module and in said piece of furniture / container. when said abutments bear on said support means, said receptacle is disposed horizontally in said piece of furniture / said container.
- the container has a plurality of support means, it is possible to maintain the base module at different levels in the container. The user can thus vary the volumes of the hot and cold zones according to his needs.
- the heat generating means or the cold generating means are removably mounted on the base module.
- said device may further comprise a complementary receptacle adapted to be mounted on said means for producing heat / cold especially when they are removed from said base module.
- a base module that heats a first receptacle while another element formed by the cold generating means refrigerates the complementary receptacle.
- the regeneration means are external to the basic module.
- the device according to the invention comprises means for heating said reactor, able to be brought into contact with said reactor, the latter being removably mounted on the base module.
- the basic module thus has no electrical element and is therefore easily washable with water.
- the base module may comprise at least one box containing the thermochemical system and separated into two compartments by said insulating element.
- the module is thus easy to transport.
- the box may be of thermally insulating material.
- the box is formed of two separable boxes, a box comprising said reactor the other said tank.
- This variant makes it possible to dissociate the means for producing heat and the means for producing cold and to use them side by side, for example.
- the box may include lateral stops which allow its mounting on a piece of furniture or in a container, for example. These stops can also serve as module gripping means.
- each box may include lateral stops.
