Definitions

  • the present invention relates to an apparatus for the active ice production of ice in household appliances, comprising at least one water bowl in which the water to be cooled is stored, said bowl comprising at least one metal, and wherein the water bowl has a wall provided with at least one channel for a refrigerant is equipped.
  • Devices for producing ice in household appliances are known in the art. There are a variety of ice makers for installation in household refrigerators. These ice makers use the low temperatures in the freezer to freeze water. Once the water is frozen, the container for the water is heated electrically and ejected the now loose pieces of ice with moving elements from the shell, described by way of example in JP 200500095 A. In this case, the water cools by heat transfer to the cold ambient air, so this device is only suitable for installation in a freezer compartment. Another possibility is to actively cool an ice maker by a cooling medium. The ambient temperature must then not be lower than 0 ° C, so that these devices is also suitable for use in small household appliances.
  • WO 03/054458 A1 describes by way of example a possibility of immersing cooled fingers in water so that an ice layer grows up.
  • the pieces of ice can be triggered by an electric heater or by switching the cooling circuit.
  • the disadvantage of this solution is that a considerable amount of water is not frozen. This residual water must either be disposed of, resulting in significant water consumption, or it will be reused several times, which can lead to hygiene problems.
  • the object is achieved with the features of claim 1.
  • Advantageous embodiments and developments, which can be used individually or in combination with each other, are the subject of the dependent claims.
  • the inventive device for the active production of ice is based on the features of the preamble in that the wall of the water bowl is in direct contact with the refrigerant.
  • the device according to the invention for the production of ice in household appliances is characterized by a very compact construction, whereby the space requirement is considerably reduced.
  • the systems, where fingers dip into the water to form a layer of ice on the fingers have a much greater footprint than the fingers, which must have as large a surface area as possible to achieve faster icing and icing have to be pulled out of the water at the top.
  • the device according to the invention is characterized by a high freezing capacity, since the water to be cooled over the wall of the water bowl is in direct contact with the coolant, whereby a much better cooling is achieved in contrast to air cooling.
  • the water bowl, in which the water to be cooled is stored, a much larger surface than the finger systems.
  • the present invention is advantageous because it does not, e.g. In finger systems, residual water is present, which can not be frozen, so either must be removed or used multiple times, both of which is technically unsatisfactory.
  • the present invention is very inexpensive because no separate heating is required to harvest the recovered ice.
  • the number of channels can be selected as required. Numbers between 1 and 20 are preferred, more preferably between 3 and 15, and most preferably between 5 and 10 channels.
  • the device has a means for manual and / or automatic water supply. If the device has a means for automatic water supply, it can be combined with a means for determining the fill level of the water dish. If water is ejected as ice after freezing, and by this means the information is conveyed that no more ice is in the shell or a defined water level was undershot, a supply of further water can be triggered.
  • This means for determining the water level may be a level sensor or a level detector, which works for example with optical means or determines the level via a resistance measurement.
  • the device can have a data interface and / or a central control via which the filling processes mentioned can be regulated.
  • the time can be programmed via a control panel, after which the frozen water is ejected and replaced by inflowing water.
  • the water bowl has a means for supplying heat to trigger the frozen liquid, by means of which the frozen water can be removed in a simple manner from the water bowl.
  • the device has at least one means for automatic and / or manual water supply. This makes it possible, after removing frozen water, to quickly supply new water, thus ensuring rapid and effective ice production.
  • the device has a means for H cataloggasabtau- ung. This has the great advantage that no special heating is required, which significantly reduces the manufacturing costs, the space requirements and the energy requirements of the device.
  • the present invention can be aptly described as follows:
  • a preferred embodiment of the invention describes a compact device for producing water ice, which allows a very high utilization of the water.
  • a shell of metal is equipped with an evaporator (e.g., coil, rollbond, or drilled channels) for refrigerant.
  • the shell is not moved, the ejection of the pieces of ice takes place with suitable ejectors, as soon as this is solved by a corresponding heating of the shell (by electric heating or H adoptedgasabtau). Due to the direct contact of the refrigerant with the metallic ice tray good heat transfer and consequently a higher freezing capacity is achieved than when cooling the ice tray by cold air.

  • This water dish 2 comprises at least one metal.
  • the water bowl has a wall 3, which is equipped with partitions 4a, 4b, 4c, 4d, 4e.
  • the wall 3 of the water bowl 2 is in direct contact with the refrigerant via a coolant channel 7 (not shown). This ensures a particularly advantageous and effective cold transmission.

  • the coolant flowing in the coolant channel 7 cools a water basin 2 which has a wall 3.
  • the invention can be aptly described as follows: a shell is cooled by at least one coolant channel.
  • the shell may be an ice tray with internal refrigerant channels defined by drilling or the mold. But it can also be a shell having a preferably flat bottom, which is thermally conductively connected to a flat evaporator such as a Rollbond board. But it can also be a massive shell with semi-open U-shaped channels on the underside, into which a refrigerant-carrying pipe was pressed.
  • the device can have shell intermediate walls which separate the individual pieces of ice.
  • the refrigerant channels lie below the shell, and are formed by a U-shaped tube, in principle, the intermediate walls may be formed hollow and refrigerant, but this is not necessary due to the high thermal conductivity of the shell.
  • the shell may be made of aluminum, but there are also conceivable high thermal conductivity plastics. The high thermal conductivity allows a greater distance between the water and the refrigerant channel.
  • the device would also be feasible with a material with a poorer thermal conductivity, in this case it would be useful to provide several, preferably more complicated shaped channels, for example in the intermediate walls.
  • the device may have ejector, since for security reasons, the shell is fixed. If flexible refrigerant pipes are used, the bowl can be rotated so that no ejectors are required. If a flexible and heat-conducting material is used instead of aluminum, no additional heating must be provided, as can be done for example by a hot gas defrost.
  • the device for the active production of ice ensures a high freezing capacity at the same time effective energy utilization and low space requirements.
