Definitions

  • the invention relates to a refrigerator with a condenser.
  • Conventional household refrigerators usually have a heat-insulating inner container with a coolable interior, which is cooled by means of a refrigeration cycle.
  • the refrigeration cycle includes an evaporator, a compressor and a condenser, e.g. has the form of a statically cooled heat exchanger, which is attached, for example, to the back of the refrigerator and emits heat to the environment of the refrigerator by radiation and convection.
  • the object of the invention is to provide an improved refrigeration appliance, in particular an improved domestic refrigeration appliance with a condenser.
  • a refrigeration appliance is understood in particular to be a household refrigeration appliance, that is to say a refrigeration appliance used for household purposes or possibly even in the gastronomy sector, and in particular for storing food and / or beverages in household quantities at specific temperatures, such as, for example, a refrigerator, a freezer , a fridge freezer or a wine storage cabinet.
  • a refrigeration device comprising a heat-insulating inner container with a coolable interior, a refrigeration circuit for cooling the interior, which comprises a condenser arranged outside the inner container, and a lonenwindgebläse which is adapted to generate an air flow, at least partially generated by the condenser heat in the environment of the refrigerator move.
  • the refrigeration device accordingly comprises a refrigeration cycle for cooling the interior.
  • the refrigeration cycle includes, as is customary, inter alia, the condenser, which is arranged outside of the inner container or optionally outside of a housing of the refrigerator.
  • the condenser which is designed in particular as a statically cooled heat exchanger, releases heat to the environment during operation of the refrigerator according to the invention. Due to its heat creates an air movement, due to which the heated air is discharged into the environment.
  • the refrigeration device comprises the ion wind blower which generates the air flow in order to at least partially move the heat generated by the condenser into the environment of the refrigeration device, in particular to blow it. This can increase the efficiency of the condenser.
  • ion wind blowers are familiar to the person skilled in the art.
  • An ionic wind is understood to mean a directed flow of ions, which is generated, for example, by a gas discharge which starts from an electrode lying at a particularly positive high voltage. The ionization is carried out in particular by removal of electrons. The generated positively charged ions are e.g. accelerated away from this electrode along a field gradient. At a further electrode opposite the electrode, the ions in turn take up electrons.
  • An advantage of an ion wind blower is that it is very quiet, if not silent, because it does not include moving parts.
  • An ion wind blower comprises a high voltage source and a plurality of electrodes and may be configured to consume relatively little energy as compared to the remainder of the refrigeration apparatus.
  • the condenser is preferably arranged on a rear side of the refrigeration device.
  • the condenser may be arranged outside of a possibly existing housing on the rear sides thereof outside the refrigeration device.
  • the ion wind blower can be arranged according to an embodiment of the refrigeration device according to the invention above the condenser.
  • the ion wind blower is preferably designed such that it generates a sucking air flow in order to at least partially upwardly suck the heat generated by the liquefier.
  • the ion wind blower is arranged below the condenser.
  • the ion wind blower is preferably designed such that it blows the heat generated by the condenser at least partially from bottom to top.
  • the ion wind blower may have a device for at least partial removal of dust from the air stream.
  • This variant is particularly well suited in connection with the arrangement of the ion wind blower below the condenser, wherein the ion wind blower blows the heated air from bottom to top.
  • Ion wind blowers usually have a plurality of electrodes.
  • the device for the at least partial removal of dust from the air stream is designed as a pair of electrodes, which is used in particular for generating the air flow.
  • the ion wind blower may include a voltage generator that generates a high voltage.
  • This high voltage can be a DC voltage.
  • the ion wind blower is designed as a pulsed plasma actuator and comprises a voltage generator generating a high-frequency alternating high voltage.
  • the refrigerator according to the invention results in an increase in efficiency, especially of household refrigerators with condenser, in particular with static condenser by convection support by means of ion wind blower.
  • the ion wind blower supports at least the transport of heat generated by the condenser in the environment of the refrigerator according to the invention.
  • the ion wind blower usually comprises a high voltage source and a plurality of electrodes. With a suitable arrangement of the electrodes, these can at the same time act as an electrostatic filter, which, for example, deposits dust in front of the condenser and thus optionally keeps the condenser dust-free for a relatively long time.
  • the electrical power required to operate the ion wind blower can be relatively small. For safety reasons, it may be necessary to limit the maximum possible electrical current to less than 1 mA. For the operation of the ion wind blower and much smaller electrical currents can be sufficient. For example, the ion wind blower requires at a high voltage of 10 kV and an electric current of 10 ⁇ A only 0.1 W.
  • the efficiency of high voltage generation can be crucial.
  • Corresponding power supplies can also be designed to be relatively energy efficient. If the ion wind blower comprises an air cleaner, then this can also be designed such that the energy consumption of the ion wind blower increases only relatively small.
  • the height of the electrical voltage of the ion wind blower determines the speed of the air flow.
  • an ion wind blower can also generate unwanted ozone, the amount of which also depends on the level of the electrical voltage of the ion wind blower. If too high an electrical voltage is used, producing relatively much ozone, then the ion wind blower may e.g. a suitable catalyst (e.g., nano-scale titanium dioxide) to convert the ozone to harmless divalent oxygen.
  • a suitable catalyst e.g., nano-scale titanium dioxide
  • the ion wind blower allows a noiseless operation.
  • the Lonenwindgebläse allows a relatively high efficiency and a relatively low energy consumption.
  • the Lonenwindgebläse allows a relatively simple structure.
  • the FIG. 1 shows a household refrigerator 1 as an example of a refrigerator in a perspective view.
  • the household refrigerator 1 whose side view in a sectional view the Fig. 2 shows, has a body or a housing 2 and a heat-insulating inner container 3 with a coolable interior 4.
  • the household refrigerator 1 is z. B. a household refrigerator.
  • the household refrigerator 1 further comprises a refrigeration cycle for cooling the interior 4, which is controlled by a control device, not shown, so that the interior 4 has at least approximately a preset target temperature.
  • the refrigeration cycle includes e.g. an evaporator, not shown, a arranged on the back of the housing 2 of the household refrigerator 1 condenser 10, and one e.g.
  • the condenser 10 is in particular a statically cooled heat exchanger through which coolant flows during operation of the household refrigerating appliance 1 and which emits heat to the environment of the household refrigerating appliance 1 by radiation and convection.
  • the condenser 10 is z. As a Drahtrohrvermounter.
  • the household refrigerating appliance 1 has, for example, a door leaf 5 hinged to the housing 2 by means of hinges for closing the interior 4. When the door leaf 5 is open, the interior 4 is accessible. At the directed towards the interior 4 Side of the door provided for closing the interior 4 door leaf 5 5 5 several door racks 6 are arranged in the case of the present embodiment.
  • a plurality of shelves 7 are arranged one above the other in the interior 4 for storing refrigerated goods and in the lower region of the interior 4, a drawer 8 is provided which can be at least partially pulled out of the interior 4.
  • the household refrigerating appliance 1 has an ion wind blower 13.
  • ion wind blowers are familiar to the person skilled in the art.
  • An ionic wind is understood to mean a directed flow of ions, which is generated, for example, by a gas discharge which starts from an electrode lying at a particularly positive high voltage.

At a further electrode opposite the electrode, the ions in turn take up electrons. By the ion wind, an air flow 14 can be generated.
  • the ion wind blower 13 comprises an electrical voltage source 15 which generates a high electrical voltage.
  • the electrical high voltage is in the in the Fig. 3 shown ion wind blower 13 a voltage of relatively high frequency (high frequency).
  • the ion wind blower 13 is designed in particular as a pulsed plasma actuator. But it can also be used a Lonenwindgebläse whose high voltage is a DC voltage.
  • the voltage source 15 of the ion wind blower 13 is on the one hand with at least one air-side electrode 16, which is designed in particular as a pair of electrodes, and on the other hand connected to an insulated electrode 17.
  • the air-side electrode 16 may be embodied, for example, as a wire electrode or a toothed sheet metal electrode.
  • a dielectric 18 e.g. Teflon or Kapton
  • a high frequency plasma 19 is still provided for the ion generation.
  • the condenser 10 is attached to the back of the housing 2 of the household refrigerator 1.
  • the Lonenwindgebläse 13 is mounted above the condenser 10 at the back of the housing 2 of the household refrigerator 1 and is oriented so that it generates an upwardly sucking air flow 14, which sucks the heat generated by the condenser 10 upwards.
  • the Lonenwindgebläse 13 may be provided with a Berschreibtik 12, which can protect the entire condenser 10 from touching.
  • the ion wind blower 13 is disposed above the condenser 10 and sucks the waste heat of the condenser 10 upwards. It is also possible that the ion wind blower 13 is arranged below the condenser 10 in particular such that it presses the air flow 14 from the bottom up.
