Definitions
- the invention relates to a refrigerator according to the preamble of claim 1.
- the invention has for its object to design a refrigeration device so that butter can be stored in spreadable condition and still takes place no excessive heat input into the interior of the refrigerator.
- a Peltier element has the property that it draws heat energy on one side with applied electrical voltage and feeds it to the opposite side. This means that the temperature of one side of the Peltier element is raised approximately to the same extent as the temperature of the other side of the Peltier element is lowered. Consequently, by using a Peltier element, a region of the inner space can be heated, at the same time supporting the cooling of the inner space. The actual total heat input is therefore limited to the Ohmic losses in the Peltier element itself.
- a first region of the interior e.g. a butter compartment
- a second area opposite the interior can be additionally cooled.
- Such an additionally cooled area can be used, for example, for the storage of beverage bottles or the like. It thus becomes possible in this way to store foodstuffs which require storage with temperature raised in relation to the interior, but at the same time other foods, such as e.g. Keep beverages that require a lowered compared to the interior temperature.
- the hood should not be made of transparent material such as Plexiglas as usual, but from insulation material. In this way, the introduced heat energy can be limited to the area of the butter compartment and thus does not spread in the interior of the refrigerator.
- a Peltier element is mounted on a conventional shelf.
- the Peltier element is switched so that the warmer side is facing up, while the colder side touches the shelf. This ensures that other parked on the shelf food does not also heat, as is additionally cooled by the Peltier element of the shelf.
- a shelf is provided with a cutout in which a Peltier element is inserted.
- a Peltier element is inserted in this way, both the colder and warmer side of the Peltier element is freely accessible.
- both the warmer side e.g. for storage of butter and the colder side e.g. be used for the storage of drinks.
- Peltier element can also be mounted in the manner of a shelf on the side wall of the interior. Again, there is a good accessibility of the two different tempered sides, so that these two sides can be used here.
- the warmer side of the Peltier element is directed upwards and, for example, butter is stored on this side, then it may happen that the butter heats up much more on its underside than inside the piece and on the upper side.
- the piece of butter should have as uniform a temperature as possible everywhere, it is proposed to switch the Peltier element so that the warmer side is directed downwards. If the butter compartment is located at the bottom of the Peltier element, the butter is heated only by radiation and convection. Heat transfer via a contact surface is eliminated in this way.
- a switch is provided, with which the voltage applied to the Peltier element voltage can be reversed. With such a reversal, the warmer and the colder side of the Peltier element are reversed. If, for example, a compartment is provided on the warmer side, in which butter is normally accommodated, this compartment can also be used for storage after the supply voltage has been reversed in polarity other foods that must be stored cooler than the normal internal temperature of the refrigerator.
- the Peltier element can be supplied with a voltage that is adapted to the preselected internal temperature of the refrigerator.
- the temperature of the Peltier element is particularly advantageously controlled thermostat-controlled and independent of the internal temperature of the refrigerator adjustable.
- FIG. 1 shows a shelf 1, in which a Peltier element 2 is integrated.
- the cutout in the shelf 1 is rectangular and adapted to the Peltier element 2 used.
- the Peltier element 2 used in the shelf 1 is freely accessible on its top and bottom.
- the size of the Peltier element 2 is slightly larger than a commercial butter dish 3 for a 250 g piece of butter, which is placed on the Peltier element 2.
- the Peltier element 2 generates heat on the one side and cold on the side opposite it.
- a certain increase in temperature on the hot side of the Peltier element 2 corresponds to just such a decrease in temperature on the cold side.
- a temperature increase of 3K on the hot side is approximately equal to one Temperature reduction of -3K on the cold side in each case with respect to the ambient temperature.
- the Peltier element 2 is used in the refrigerator to heat a butter compartment 4 so that the butter remains spreadable. So that no additional heat from the hot side of the Peltier element 2 is entered into the cooled interior of the refrigerator, the butter compartment 4 is covered by a hood 5. Particularly advantageous is the hood 5 made of a heat-insulating material. The hood 5 is dimensioned so that the Peltier element 2 is reliably straddled and finds a commercial butter dishes 3 place below.
- the cold side of the Peltier element 2 has a temperature lowered to the cooled interior. This is used, for example, to continue cooling down beverage bottles 8, as would be possible with the cooled interior.
- a cooling compartment 6 is attached to the underside of the compartment 1 in the region of the Peltier element 2.
- the cooling compartment 6 is bounded by a U-shaped trough 7, which is accessible from the front and serves as a bottle holder.
- the distance between the legs to each other is on the one hand at least as large as the width of the Peltier element 2 itself, on the other hand, commercial beverage bottles 8 must find space in the refrigerator compartment 6.
- the tray 7 In order to make optimal use of the temperature gradient of the refrigerating compartment 6 with respect to the cooled interior, it is also possible for the tray 7 to be produced in an advantageous manner from a heat-insulating material.
- the control of the Peltier element 2 is effected by a thermostat, not shown here, the sensor is mounted in the butter compartment 4.
- the temperature in the butter compartment 4 is regulated independently of the temperature of the cooled interior to a preset value. Since the cold and warm side of the Peltier element 2 is determined by the current direction of the direct current, it is even possible to cool the butter compartment 4 if the "cooled interior" is warmer than the desired temperature in the butter compartment 4. However, then the cooling compartment 6 becomes heat fed. Since not only heat for the butter compartment 4, but also cold for the refrigerating compartment 6 is generated in the cooled interior, the Peltier element 2 acts only to a very limited extent as a heat source. The heat input of the Peltier element 2 into the cooled interior is basically limited to the power loss of the Peltier element 2, which is converted into heat.
