    [0001] The present invention relates to a container with autonomous regulation of the temperature, in particular intended for the transport of thermosensitive products in climatic environments likely to be subjected to sudden and important variations of temperature. Containers of this type are known which are generally used for transporting foodstuffs and thermosensitive or perishable products, such as for example drugs, and which consist of an enclosure inside which one or more plates are arranged. eutectics which are brought to a more or less low temperature depending on the level of cooling that it is desired to apply to the products arranged in the container.
    [0002] One of the difficulties specific to this type of container is that the user is forced to know in advance the profile of the temperatures to which the container will be subjected during transport to determine the nature, temperature and number of plates. eutectic to dispose in the box. It is understood that, under these conditions, any abrupt change in the temperature profile encountered during transport can have adverse consequences on the maintenance of the cold chain applied to the transported product. Moreover, the user is forced to have a collection of eutectic plates of different refrigerating capacities. The object of the present invention is to propose a container, in particular intended for the transport of thermosensitive products, which is provided with means capable of enabling it to autonomously and automatically regulate the storage temperature of these products so that it can be subjected to during a given period of time, to very different temperature profiles while keeping in the storage box the desired setpoint temperature. Another object of the present invention is to propose means enabling a user of a range of containers of this type whose capacities are varied to move quickly from one to the other so as to be able to respond quickly. and easily to its different specific needs. The subject of the present invention is thus a container with autonomous regulation of the temperature to a determined set value of the type comprising at least one series of two compartments, namely a receiving compartment of said products and a compartment able to deliver cold or heat. hot, hereinafter called "hot / cold compartment" characterized in that it comprises: - means capable of creating a flow of air circulating through the receiving compartment and the hot / cold compartment, - means able to regulate the air flow, the aforesaid means being grouped in at least one extractable module housed in an additional compartment. The additional compartment can be divided into two sub-compartments, namely an upper sub-compartment in which the module will be housed and a lower sub-compartment through which the flow of air coming from the receiving compartment and going towards the hot compartment will pass. /cold. The airflow can be generated by a fan that will be housed at the base of the module and that will draw air into the receiving compartment to propel it into the hot / cold compartment via the lower additional subcompartment. Advantageously one of the sides of the module will be provided with an open housing on an air intake orifice made in the wall separating the upper subcompartment containing the module of the receiving compartment. This housing may include a deflector deviating to the lower sub-compartment the air flow from the receiving compartment. The means capable of measuring the temperature of the air of the receiving compartment may consist of a probe, in particular disposed on the deflector. In an advantageous variant of the invention, the means for regulating the air flow may take into account the difference existing between the ambient ambient temperature at which the container will be subjected during its operation with the set temperature. This regulation of the air flow can be done by adjusting the speed of rotation of the fan. In another variant of the present invention the hot / cold compartment and the receiving compartment will be separated by an adjustable wall in position to vary the volume of the hot / cold compartment. An embodiment of the present invention will be described hereinafter by way of nonlimiting example, with reference to the appended drawing, in which: FIG. 1 is a perspective view of a container with autonomous regulation of the temperature according to the invention, - Figure 2 is a perspective view of the container shown in Figure 1, the operating module is shown in the extraction position, - Figure 3 is a perspective view of the operating module of the container shown in Figures 1 and 2, - Figure 4 is a schematic view of the constitution of the operating module controlling the temperature control of the container according to the invention. FIG. 1 shows a self-regulating container 1 of the temperature according to the invention which consists essentially of an enclosure 2 made of an insulating material, such as, in particular, expanded polypropylene, the interior of which is separated into several adjacent compartments, namely a compartment 3a disposed in an angle of the enclosure 1 and which extends over part of the width of the container, a compartment 3b disposed along the remaining portion of the width, and a compartment 3c, or receiving compartment, occupying the rest of the volume of the container. The container 1 is closed by a cover not shown in the drawing. The compartment 3a receives a module 5, hereinafter referred to as "operating module", which is intended to manage the operation of the whole of the container 1. This operating module 5, of substantially cubic shape in the present mode of implementation of the invention, comprises, as shown in FIG. 4, management means in particular constituted by a microcontroller 7 which controls the operation of a fan 9, a temperature measurement probe 11 and a Electrical supply for a heating resistor 13. Furthermore, the operating module advantageously comprises integrated power supply means consisting in particular of a rechargeable battery 15 to which is associated a mains-reloading block 17, possibly removable. As shown in FIG. 3, the operating module 5 has on one of its lateral faces an opening giving access to a housing 6 whose base is constituted by the fan 9 and the ceiling 8 which is inclined at 45.degree. a deflector which receives the probe 11 for measuring temperature. The compartment 3b, hereinafter called "hot / cold compartment", which is adjacent to the compartment 3a is intended to receive, in one embodiment of the invention, cooling means, in particular constituted by eutectic plates. or dry ice. It is in communication with the compartment 3a through an orifice 21 disposed in the lower part of the partition 4a separating these two compartments. The operating module 5 is arranged in the upper part of the compartment 3a, in a sub-compartment 3a ', so that the opening of the housing 6 is in communication with the receiving compartment 3c by an air intake port 10 dug in the partition wall 4b of these two compartments. The hot / cold compartment 3b is also in communication with the receiving compartment 3c, through an orifice 23 disposed in the upper part of the partition wall 4b of these two compartments. The bottom of the control module 5 receives the fan 9 which is driven in a direction of rotation such that it creates a flow of air from the receiving compartment 3c to the hot / cold compartment 3b through the orifice 10, then orifice 21 to enter the hot / cold compartment 3b where it undergoes a cooling (or a warming depending on the cold or hot product it contains), and enter the receiving compartment 3c where it mixes with the air from it by cooling or reheating as appropriate. The upper face of the control module 5 comprises a display screen 24 on which is displayed the temperature of the air sucked by the fan 9 into the receiving compartment 3c which is communicated to it by the microcontroller 7 from the data measured by the probe 11 and which is also used to adjust the set temperature. Under these conditions the operation of the container according to the invention is as described below. The products to be kept at a determined set temperature Tc are arranged in the receiving compartment 3c and, if the outside temperature T is greater than the set temperature Tc, a product capable of producing cold is placed in the compartment 3b. For example, the eutectic plates 19. In the opposite case, the heating resistor 13 is placed in the hot / cold compartment 3b or it is electrically connected if it is already in place. From then on the microcontroller 7 will control the heating of this resistance. Then, after closing the container, activating the operating module 5 after setting the set temperature Tc to the desired value. The fan 9 starts up and draws (arrow A figure 2) the air of the receiving compartment 3c through the orifice 10 and the temperature of this air is measured as it passes on the probe 11 by the latter, then the flow air is sent by the fan 9 to the lower compartment 3a "then, through the opening 21 (arrow B) in the hot / cold compartment 3b.Through it, it cools in contact with the plates eutectic 19 then it is sent through the orifice 23 (arrow C) in the receiving compartment 3c where it cools the air thereof.
    [0003] When the temperature of the receiving compartment 3c reaches the set temperature Tc, the measurement probe 11 sends this information to the microprocessor 7 and the latter controls the shutdown of the fan 9.
    [0004] According to the invention the temperature regulation can be progressive. To do this, upon receipt of the value of the temperature T existing in the receiving compartment 3c, the microprocessor 7 determines the difference in temperature 6T = T-Tc existing between this temperature and the set temperature and the greater this difference is important. and more the microcontroller controls a high speed of the fan 9. In this way the set temperature Tc is quickly reached initially and, during normal operation, the value of the temperature oscillations around the set temperature is reduced. The operating module 5 is advantageously provided with a gripping handle 25 which enables the user to easily extract it from the subcompartment 3a 'and then to put it back into place therein or in the appropriate compartment of the subcompartment 3a'. another container. The invention is particularly interesting in that the operating module can be easily moved from one container to another, which allows, by means of a standard type module, to be able to operate containers of different powers. In an alternative embodiment of the present invention the container may include several operating modules 5 which will allow the user to increase the power or volume of the speakers used according to his needs. In another alternative embodiment of the invention, the separating wall 4b may be mounted so that it is displaceable thus making it possible to vary the volume of the hot / cold compartment and consequently the amount of refrigerant storable in the latter. . -
