Definitions

  • the invention relates to a container for receiving foods intended for early consumption, which are kept in an interior of a refrigerator and which, at the usual cooling temperatures in the refrigerator, have a consistency which is poorly suited for their consumption, with a container interior which accommodates the food and which is enclosed on all sides by walls is.
  • butter containers in which pieces of butter are kept, which are to be used, for example, as a spread or as an ingredient in the preparation of dishes.
  • These butter containers usually consist of a base on which the piece of butter rests and a hood that can be removed from the base.
  • the hood protects the butter from odors present in the ambient air and thus largely prevents the taste of the butter from being adversely affected by the absorption of foreign substances.
  • a butter container is expediently kept in a cooler environment compared to the usual room temperature during the time when the butter contained in it is not to be used.
  • a refrigerator is usually used for this, since such a device is also available in almost every household and is usually also installed in the kitchen, where the largest amount of butter procured for the household is usually consumed.
  • the storage of a conventional butter container in the refrigerator has the considerable disadvantage that the butter contained in the butter container is cooled very quickly to the interior temperature of the refrigerator by the good heat conduction of the container materials used.
  • this temperature is usually set so low that even perishable foods such as meat or cold cuts can be stored, the butter can no longer be spread when removed from the refrigerator. This makes it almost impossible to evenly distribute them on a slice of bread or a bun len. In the case of appropriate tests, especially soft white bread slices and light pastries are often crushed or torn and offer an unaesthetic sight after the spreading process has ended.
  • the butter would have to be taken out of the refrigerator in time so that it could absorb enough heat from the environment. If the butter is taken too early, it will become so soft that its use will be impaired. In addition, the butter spoils much faster at room temperature than at lower temperatures. The butter should therefore not be kept at room temperature for an unnecessarily long time.
  • This object is achieved according to the invention in that a temperature maintaining the consumption-related consistency of the food is provided in the interior of the container.
  • the container can be designed as a unit connected to the refrigerator and permanently installed in it, or as a separate unit that can be removed from the refrigerator.
  • Common to all types of training is thermal insulation of the container interior from the refrigerator interior.
  • training as a ready unit is also to be thought of a form of training in which the container according to the invention specifically meets the requirements of storing butter and the temperature which corresponds to an optimal consistency is only maintained passively via the suitably dimensioned container insulation.
  • the cooling of the butter inside the refrigerator is considerably delayed. Due to the generally short periods of time that butter is exposed to room temperature during meals, its temperature does not increase significantly during this time. Butter that was at an optimal spreading temperature when the butter container was removed from the refrigerator is therefore stored in the butter dish in the refrigerator again at the end of the meal in a state that is only at a slightly higher temperature level than the desired spreading temperature. If the butter dish is in the refrigerator for a normal period of time, the insulation according to the invention can be used to prevent the butter from cooling to a temperature which is substantially below the optimum spreading temperature.
  • the butter dish consists of three individual parts.
  • a base plate which is made of metal or plastic, for example, a bowl made of a heat-insulating material is embedded, which serves to hold the piece of butter to be kept.
  • a suitable plastic for example a suitable plastic.
  • double-walled production from a transparent plastic should also be considered. Due to the double-walled design, the air trapped between the landings provides adequate thermal insulation even with a plastic with lower insulation properties of the butter container.
  • the use of transparent materials enables easy visual control of the cleanliness of a butter container in use. This property is of great importance given the high hygienic requirements for appliances used in the home.
  • a thermostat-controlled heating device is provided to increase the temperature in the interior of the container.
  • the heating device is designed as an electrical heater and is supplied with energy, for example, by a battery or an accumulator.
  • the heating is switched on by a thermostat switch and heats the interior of the container until a temperature level slightly above the temperature corresponding to an optimal consistency is reached.
  • a flap is provided for removing the stored food, which is preferably to be opened in the direction of the refrigerator door.
  • the flap can be pivotally mounted in the wall of the container, but it is also possible to design the flap so that it can be removed from the container wall.
  • the energy is preferably supplied via a transformer from the electrical supply network connected to the refrigerator.
  • the energy supply of the container can also take place via this transformer.
  • the container heating can be fed with DC using appropriate voltage converters.
  • the energy supply for a container heater can be provided from the circuit of the refrigerator via coupling pieces.
  • an area of the refrigerator interior that is provided for the regular storage of the container needs to be equipped with a counterpart that matches the container contacts and that has the necessary electrical connections to the circuit of the refrigerator.
  • a container designed as a unit which can be removed from the refrigerator and intended for holding butter essentially consists of a base plate 1, a hood 2 and a bowl 3 serving to hold the butter.
  • the hood 2 and the bowl 3 are made of heat-insulating material. A particularly good one Insulation results if the hood 2 is double-walled. In a cavity 1 that is between walls. 5 and 6, air is trapped. The shell 3 can also be double-walled to increase the insulation effect. Air is also enclosed in a cavity 7 between walls 8 and 9.
  • Butter 10 located on the dish 3 can thus be stored for a long time in a refrigerator 11 with the aid of the feed container without the butter 10 being cooled to the low temperature in the interior 12 of the refrigerator 11.
  • the butter remains spreadable for a long time.
  • the container can also be designed so that an electrical heater 14 is provided to increase the temperature in the container interior 13.
  • an electrical heater 14 is provided to increase the temperature in the container interior 13.
  • the base plate 1, the base part 16 and the side wall 17 are also expediently made of a heat-insulating material.
  • the bowl 3 can also be formed by a conventional serving bowl for butter. Insulating properties of the shell 3 are not necessary in the case of an insulating base plate 1 due to the all-round insulation of the food 10 from the interior of the refrigerator 12.
  • a commercially available stainless steel serving bowl can also be used.
  • the heater 14 is supplied by an energy source 18.
  • the energy source 18 can be formed, for example, by a disposable battery or a rechargeable battery.
  • the heater 14 is connected via lines 18 to the energy source 18 connected.
  • the current flow through the heater 14 is controlled by a thermostat switch 20.
  • the switching characteristic 21 of the thermostatic switch 20 has hysteresis behavior in order to achieve a quiet switching characteristic. When the temperature in the interior 13 falls below a value 22, a current flow through the heater 14 is made possible, when the temperature in the interior 13 rises above a value 23, the current is switched off.
  • the temperature values 22 and 23 are chosen so that the value 22 is below and the value 23 is above an optimal consistency temperature 24. Consistency can also be maintained if the food 10 is stored in the refrigerator for a long time.
  • the recesses 25 in the base plate 1 allow the air heated by the heater 14 to rise from an interior 26 of the base part 16 into the interior 13 surrounding the food 10. Due to the thermal insulation of the container, the air in the interior spaces 13 and 26 remains sufficiently long to mix through the recesses 25 to such an extent that the thermostat switch 20 can influence the temperature of the food 10 with sufficient accuracy.
  • the energy source 18 is fixed in the base part 16 by webs 28. Through a recess 29 in the base part 16, a used energy source 18 can be removed in a few simple steps and replaced by a ready-to-use new energy source.
  • the base plate 1 forms a common part with the walls of the refrigerator 11.
  • Walls 30 the container is closed to the refrigerator interior 12 and thermally insulated. Food stored in the container interior 13 can be removed through a flap 31.
  • the flap 31 can be pivotally mounted in the walls 30 or in the base plate, but it is also possible to provide the flap 31 in a removable manner and to fasten it to the container, for example, by means of plug fits.
  • the energy supply of a container permanently installed in the refrigerator 11 is preferably carried out via a transformer 32 from the transmission network 33 which is usually connected to the refrigerator 11.
  • An external energy supply to the container heater 14 can also be provided for a container that can be removed from the refrigerator 11.
  • the container circuit is connected to the circuit of the refrigerator via contacts 34 and sockets 35 attached to the container and fastened in a holder 36 in the refrigerator interior 13.
  • the circuit of the refrigerator is led to the sockets 35 via lines 37.
