Definitions

  • the invention relates to a temperature-insulated container having an interior which is bounded by an insulated wall. Furthermore, the temperature-insulated container has a device for active temperature control of the interior, wherein the means for active temperature control of the interior is provided in or on a region of the wall.
  • the temperature-insulated container may preferably be a cooling box.
  • the device for active temperature control of the interior can be designed, for example, as a Peltier element.
  • Peltier element If a Peltier element is supplied with energy, in particular electricity, then one side of the Peltier element is cooled and thermal energy is shifted to the other side. This page is therefore warmed up.
  • the Peltier element can therefore generally be referred to as a heat pump.
  • the cooling capacity or energy efficiency depends on the temperature differences between the hot and cold sides. The lower these are, the more energy-efficient the cooling can be carried out by means of a Peltier element. Therefore, on the warm side of the Peltier element often a device for surface enlargement, such as cooling fins attached. These serve to better release the heat energy to the environment.
  • a wall in the context of the invention, all walls, the lid and the bottom of a temperature-insulated container are understood. This means that the wall is the whole of the walls, the floor and the cover. In this case, the walls need not necessarily be straight, but may also have a curved shape, for example concave or convex.
  • an insulated housing with one or more subjects are considered, which is intended for the cooling or freezing of food or storage of chilled or frozen food for non-commercial purposes and by cooling one or more energy consuming processes, including devices sold as kits for assembly by the user.
  • the cooling capacity depends on the device used for active temperature control and on the insulation of the cooler.
  • the device for active temperature control must generate a delta T of 18 ° C. This is only possible when using Peltier elements, if the wall insulation of the cool box, that is the wall, has a sufficiently good quality. This means that a sufficiently good thermal insulation through the wall is made possible.
  • the external volume of the cooler is increased compared to the internal volume.
  • the legislator has introduced energy consumption limits and minimum requirements with regard to the cooling capacity, in particular for electric coolers connected to house electricity with an operating voltage of approx. 230 V AC. If these limits are to be adhered to, sufficient cooling of cool boxes with 40 l is possible with an acceptable wall thickness as described above only with difficulty.
  • the invention has for its object to provide a temperature-insulated container which, despite a large internal volume allows efficient cooling, without exceeding energy consumption limits.
  • means for reducing the interior space are present and that a reduced interior space can be formed by the means for reducing the interior space and parts of the wall.
  • a basic idea of the invention can be seen in that the interior of a temperature-insulated container by a corresponding device, in In this case, special means for downsizing the interior, can be downsized. In other words, the interior can be divided into several sections. Furthermore, it is provided according to the invention that in one of these sub-area, which is referred to below as a reduced interior space, the means for active temperature control of the interior space are provided in this reduced interior space forming wall. This means that via the device for active temperature control of the interior of this reduced interior space can be further tempered. Therefore, the reduced interior space can also be referred to as actively tempered interior.
  • a cool box which has an internal volume of 40 l
  • the means for reducing the size of the interior each of which has substantially 20 l each.
  • One of these interiors is the actively cooled interior.
  • the means for reducing the size of the interior are provided in the temperature-insulated container in such a way that the reduced internal space to be actively controlled is formed by the means for reducing the interior space and a part of the wall with the device for active temperature control.
  • the device for active temperature control only needs to cool or temper a smaller interior space.
  • the device for active temperature control and the insulation of the wall can be designed so that the statutory requirements for the maximum consumption of energy are taken into account or respected.
  • the wall of the entire temperature-insulated container is not designed so strong that the entire interior, that is, the 40 l or more, can be sufficiently cooled, but the reduced interior space, which means about 20 l, are sufficiently well cooled. Furthermore, therefore, the insulation of the wall must not be carried out so strong, so that the entire temperature-insulated container maintains an acceptable ratio of internal volume to external volume.
  • the means for reducing the interior space can be designed as desired, and reduce the interior space in any desired manner.
  • a further reduced interior space can be formed by the means for reducing the interior space and further parts of the wall.
  • the other parts of the wall of the further reduced interior space in the region of the wall on no means for active temperature control of the interior.
  • the further trained interior can not be actively tempered.
  • a second refrigerating compartment is created, which is passive to cool. This can be done for example by cooling batteries.
  • the means for reducing the interior space are designed such that no further interior space is created in addition to the first reduced internal space, which can be actively tempered.
  • such an embodiment is disadvantageous because then, in comparison to the embodiment with a further reduced not actively cooled interior additional volume of the original interior would not be used.
  • the means for reducing the size of the interior can be provided in any desired manner in the interior of the temperature-insulated container.
  • the wall has means for fixing the means for reducing the interior space.
  • the means for reducing the size of the interior can be securely mounted in the temperature-insulated container or the interior, so that the means for zooming, for example, during transport of the temperature-insulated container does not slip and thus the defined actively cooled smaller interior in volume Don ⁇ t change.
  • the means for fixing the means for downsizing the interior can be embodied, for example, as grooves in the wall, wherein the means for reducing the interior space are formed as partitions which can be inserted into the grooves.
  • These partitions may preferably be designed to be temperature-insulating. As a result, a simple means is given without reducing the large overall interior of the temperature-insulated container. If the partitions are formed temperature insulated, there is a better energy efficiency of the reduced cooling area, as this is designed as a completely isolated area.
  • the partition wall is made insulated, and on the other hand, the wall is insulated.
  • the wall in the context of the invention can be understood as side walls, bottom wall and lid.
  • the device for active temperature control which can be embodied for example as a Peltier element, is arranged in a cover region of the wall.
  • the device for active temperature control of the interior can be provided at any point of the wall, however, it is advantageous to provide it in the cover area, since there is a simple attachment of the corresponding further electronics and the leads, such as cable is possible.
  • the device for active temperature control in the floor area it may be possible for the device for active temperature control of the interior to be covered by a material to be transported, so that tempering, in particular cooling, is made more difficult.
  • the device for active temperature control of the interior is designed for operation with AC voltage and for operation with DC voltage.
  • the AC voltage may be, for example, a home supply in the range of 230V.
  • the DC voltage can be for example a 12 V DC voltage of an automotive power supply.
  • the means for actively controlling the temperature of the interior can be designed such that it can only be operated with alternating voltage when the interior space is executed reduced.
  • Such a design of the device for active temperature control can achieve that, on the one hand, the maximum predetermined energy consumption limit during operation with alternating voltage is not exceeded, and on the other hand, the legally prescribed minimum required cooling capacity is still met.
  • a sensor device for detecting the reduction in the interior space can be provided, which is designed such that a reduced internal space is signaled to the device for active temperature control, or if the device can actively detect the temperature of the interior or one of its associated electronics via the sensor device if there is a reduced interior space.
  • An example of the sensor device is a contact device, which is formed in the region of the side regions of the wall. This can be provided for example in the grooves for the partitions. Thus, the contact device is activated when a partition is inserted. This makes it possible in a simple manner to recognize when a reduced interior space is present and thus provide the appropriate operating mode of the device for active temperature control. In principle, other realizations for sensor devices are possible.
  • the reduced actively cooled internal space can have a volume of substantially 30 l, advantageously 20 l.
  • This volume represents the maximum volume when operating the temperature-insulated container with a conventional Peltier element. Becoming technology innovations in the field of cooling devices considered, so this maximum to be cooled internal volume of the reduced interior can also be increased.
  • Fig. 1 is a first embodiment of a temperature-insulated container 1, which can also be referred to as a cool box shown.
  • the cool box 1 has a lid 3 and a body 4.
  • the entirety of cover 3 and body 4 can be referred to together as the wall of the cooler 1.
  • the lid 3 and the body 4 are designed to be temperature-insulated, for example of a foamed material.
  • the body 4 is formed of four side walls 5 and a bottom portion.
  • the lid 3 is a device for active temperature control, which is designed as a Peltier element 6.
  • the power supply to the Peltier element 6 can also be done via attachable to the lid 3 supply lines.
  • the interior or the inner volume of the cooling box 1 is in Fig. 1 formed in three parts. This division is effected by partitions 8 and 9. These partitions 8, 9 are also formed temperature-insulating and can be inserted into the body 4 of the cool box 1. This means that the partitions 8, 9 are not always provided there. For attachment of the partitions 8 and 9, for example, corresponding grooves in the side walls 5 of the body 4 may be provided.
  • the cooling box 1 If the cooling box 1 is closed, that is, the lid 3 is folded down, so the area of the lid 3 closes with the Peltier element 6, the middle interior 10, which is also referred to as actively reduced to reduced interior space 10 from.
  • the Peltier element 6, the middle interior 10 is still active cool when the partitions 8 and 9 are inserted.
  • Fig. 2 another embodiment of a cooler according to the invention 20 or a temperature-insulated container according to the invention is shown.
  • a Peltier element 6 is provided in the rear wall 22 of the body 4.
  • the entire interior of the cooler 20 is only two parts in contrast to the three-part interior of the cooler 1 Fig. 1 executed. This means that only one partition wall 24 can be inserted in the interior of the cooling box 20. As a result, two internal spaces 30 and 31 are formed.
  • the rear region 22 is located with the Peltier element 6, so that the inner space 30 can be actively cooled.
  • the interior 31 can analogous to the two interior spaces 11 and 12 Fig. 1 are no longer actively cooled by the Peltier element 6, but is only a passive cooling available.
  • the partitions 11, 12 and 24 in the entire interior of the cool box 1 and 20 can be fixed at any point, so that the interiors 8, 9, 10, 30, 31 can be dimensioned arbitrarily large.
  • temperature-insulated container With the temperature-insulated container according to the invention a possibility is provided to provide temperature-insulated containers, which have a large internal volume, and still allow efficient cooling, which does not exceed a maximum energy consumption, especially when operating on AC voltage.
