Definitions

  • the invention relates to a cool box for storing a good to be cooled, in particular of a food, in a sealed by a closure means Interior by means of a sorption cooling device, the cooling function of which can be triggered by a valve is.
  • Such a cool box is known from DE 41 19 507 A1.
  • the well-known cool box is a camping box, the lid of which contains a vacuum container to hold a sorption heating and / or cooling device.
  • This heating and cooling device shows that Pair of substances zeolite / water, which is independent of the power supply for several hours Cooling or heating of food enables.
  • this object is achieved in a cool box of the type mentioned solved that the valve can be actuated by the closure means.
  • This cool box can be used advantageously in the area of a household if the Cool box outside the home or in a one accessible for a delivery service Area is introduced. Then he can load the cool box with food, even if the recipient is not present.
  • the cool box frees suppliers and recipients of the need for face-to-face meetings as the cool box for example in front of the house or in front of the entrance area, for example in the garden stands, and so the goods can be deposited by the supplier in the cool box.
  • the Cool box is suitable for a variety of goods, especially frozen foods, placed in a freezer or freezer after removal from the cooler become. There are already delivery services that provide such frozen foods Transport households and so far on a personal presence of the recipient are instructed. The fact that when the closure of the cooler, i.e.
  • the valve of the sorption cooling device opened , a medium absorbing transformation energy flows - in the case of the zeolite / water system this is water vapor - from an evaporator to a container with a Pouring a sorbent, for example the zeolite, which is characterized by the Warm water intake. There is so much evaporation energy from the water consumes that this is sufficient for hours of cooling the interior of the cool box.
  • the cool box is neither connected to an electrical network nor is it present a compressor, such as that found in a refrigerator or freezer is necessary.
  • the cool box is network-independent and can therefore be used on any Place without electrical supply.
  • cool box Another advantage of the cool box is its light weight, making it lightweight can be worn. It is therefore available for various purposes.
  • the cool box can also be operated by the personnel of a frozen food delivery service the cooling process is always triggered without the personnel being involved in the operation of the Cool box must be specially instructed.
  • a cable pull can also be used the closure means is connected to the valve so that the valve opens of the closure means is also opened.
  • the closure means an electrical connection powered by a battery is connected to the valve and that the valve is opened when the closure means is opened.
  • the valve is also an electromagnetic valve.
  • the sorption cooling device advantageously has one arranged on an outside of the cool box Container with a bed of sorbent and an evaporator on, which is connected to the container via the valve and into the interior of the cool box is introduced.
  • the evaporator has the largest possible surface, to ensure good heat transfer from the evaporator to the interior of the cool box guarantee.
  • the sorption cooling device is made of Cool box removable and regenerable elsewhere.
  • the container with the Sorbent applied to a heater and heated by it, so that at open valve the water is desorbed from the zeolite. Then that will Valve closed, the sorption cooling device is regenerated and stands for that again Insert into the cool box available.
  • the container itself has a heating cartridge or a heating coil so that it regenerates on the spot or at any socket can be.
  • the cool box is connected to the electrical network turn on the heater in the tank.
  • a cool box that is activated by a key, especially an electronic one, is particularly suitable Key that is opened and locked. If only the key The owner of the cool box and the supplier of a food is available, unauthorized use of the cool box is excluded.
  • a cool box 1 (figure) has a housing 2.
  • the housing 2 includes one with a heat-insulating material filled wall, which only breaks through an opening 3, through which an evaporator 4 can be pushed into an interior 5 of the cool box 1.
  • the evaporator 4 has a large surface, for example, by a lamellar structure arises to a rapid heat transfer between the interior 5 and to ensure the evaporator 4.
  • the evaporator 4 is connected to a valve 6 Container 7 in connection, which contains a bed of sorbent 8. This is preferably a zeolite. But other raw materials are also suitable.
  • the container 7 is firmly connected to the evaporator 4 and has a heater inside, for example in the form of a heating wire or a heating cartridge 9. This can be done via Connect cable 10 to an electrical network to regenerate the sorbent.
  • the cool box 1 has a door 11 which, like the housing 2, has thermal insulation Is provided.
  • the door 11 When the door 11 is opened, it is attached to the door 11
  • Projection 12 moves an actuating linkage 13, which in turn opens the valve 6.
  • a certain amount of water occurs in the evaporator 4 under an internal pressure evacuated from below 150 hPa, into the container 7 above.
  • The is from Evaporator 4 escaping water vapor bound by the zeolite in the bed 8, so that more water evaporates spontaneously.
  • the evaporator 4 becomes a significant amount of heat is withdrawn, so that the water freezes very quickly reached.
  • Cooling capacity occurs spontaneously and is very powerful, so that a temporal upstream Cooling is not necessary.
  • This process of evaporation can of course be done by closing the valve 6 be interrupted at any time, for example if the customer does this in the cool box 1 want to remove stored food prematurely.
  • Regeneration is required after the zeolite is saturated.
  • the container 7 and the evaporator 4 firmly connected to it are removed from the cool box 1 and regenerated over a heater.
  • the bed of zeolite is regenerated by that the heating cartridge 9 is connected to the electrical network via the cable 10 becomes.
  • the water from the Expelled zeolite can be used to regenerate the zeolite.
  • the valve 6 is during the Keep regeneration process open so that the water in the evaporator 4 condenses. After cooling the container 7 and the evaporator 4, both are ready for use again, and the evaporator 4 is pushed back into the cool box 1.
  • valve 6 Instead of the actuating rod 13, which passes through a separation point 14 with the valve 6 is connectable, so that the latter is opened by a movement of the actuating rod 13 other opening or closing means can also be used, to operate the valve 6.
