Definitions

  • the present invention relates to a refrigerator and / or freezer with at least one cooled interior and at least one evaporation tray for receiving expired from the cooled interior condensate.
  • refrigerators or freezers are those with compression refrigerating machines, absorber refrigeration circuits, brine coolers or Peltier cooling.
  • evaporation tray is to be interpreted broadly and in the context of the invention includes any container for receiving condensation water.
  • the condensation water in the evaporation tray must evaporate from there.
  • different possibilities known from the prior art such as the use of compressor waste heat, optionally with additional hot gas pipe, the integration of the evaporation tray in the compressor cover, the arrangement of the evaporation tray decentralized to the compressor with a hot gas line in or under the shell, the arrangement of Evaporation bowl decentralized to the compressor with condenser and condenser fan, the evaporation tray with surface heating devices, such as an evaporation fleece, the evaporation tray arranged in floors, to increase the water surface, the evaporation by ultrasonic air atomization and the evaporation by removing moist air by means of targeted Air flow via an inlet and outlet duct arranged in the base of the device.
  • the present invention is therefore the object of developing a refrigerator and / or freezer of the type mentioned in such a way that it is ensured that a sufficient evaporation of the condensation water located in the evaporation tray takes place.
  • a refrigerator and / or freezer with the features of claim 1.
  • at least one fan module is provided, which has at least one fan, wherein the fan module is arranged and configured such that the air conveyed by the fan is supplied to the evaporation tray and that at least a part of the fan module is designed to be movable, so that it can be arranged in different positions relative to the evaporation tray.
  • the present invention is therefore based on the idea according to this aspect to provide at least one fan module, which has at least one fan whose air flow is supplied to the evaporation tray during operation of the fan.
  • the term "movably formed” is to be understood that the entire fan module or even a part of this relative to the evaporation tray is not fixed, but is flexibly positionable, so that the air flow are optimally aligned relative to the evaporation tray can.
  • An essential aspect of the invention is thus the flexible positioning of the entire fan module or a part thereof relative to the evaporation tray.
  • At least one fan exclusively associated with the evaporation tray is provided, which is arranged relative to the evaporation tray such that an air flow is generated via the evaporation tray by means of the fan during its operation.
  • At least one fan is provided, which is assigned only to the evaporation tray.
  • the fan generates an air flow which is supplied by the fan only to the evaporation tray and not to a combination of condenser and evaporation tray, etc.
  • the term of exclusive assignment to the evaporation tray does not exclude that the air flow passes from the evaporation tray to another component, such as the condenser.
  • the present invention differs from known arrangements, such as those in which the exhaust air from condenser vents is passed through evaporation trays.
  • the liquefiers are in these known arrangements z. B. arranged in aggregates in the device base or ceiling units. In these cases, an assignment of the fan to the condenser and not to the evaporation tray is thus provided.
  • the refrigerator and / or freezer is one in which the evaporation of condensation water has hitherto been realized without an actively aerated evaporation tray.
  • the condenser is arranged on the rear wall of the device.
  • the compressor is usually located in a Kompressorische and on the compressor is usually the evaporation tray.
  • there is no active ventilation by a fan In particular, for such devices, the present invention is suitable because it causes a significant increase in the evaporation performance there.
  • the invention also encompasses a combination of the two embodiments according to the invention. It is thus conceivable to make both a flexible positioning of the entire fan unit or parts and also an exclusive assignment of the fan or the fan module to the evaporation tray.
  • the fan module has at least one line, by means of which the fan supplied air and / or by means of which air is guided by the fan to the evaporation tray.
  • the fan module in this case thus has at least one fan and at least one, preferably a plurality of line sections. It is also conceivable that the fan module has a plurality of lines, which are arranged downstream of the fan and thus can provide different areas of the evaporation tray or the water therein with an air flow.
  • the at least one line in the vertical direction and / or in the horizontal direction and / or obliquely and / or in their inclination to the surface of the water in the evaporation tray is adjustable. It is conceivable that the line is flexible and / or has relatively rotatable and / or displaceable line segments. In this way, a flexible positioning of individual elements of the fan module relative to the evaporation tray is possible.
  • the fan module has a relatively small size, is flexibly positionable (even in the most confined spaces), has an operation independent of the Vertexerabowski and can be operated without consuming supply and exhaust ducts, as they are known in base units.
  • the fan is characterized by a low electrical power consumption of ⁇ 1 watt.
  • the fan need not be designed such that it generates an air flow over a plurality of components of the refrigerant circuit, for example, over the entire base unit. It is sufficient if the fan generates an air flow over the evaporation tray.
  • the fan unit or the fan is optionally equipped with devices that are operated in markets with relatively critical environmental conditions or consumer habits.
  • the fan or the fan module in a basic version and to mount this only if necessary preferably on the evaporation tray.
  • the fan or the fan module is arranged directly on the evaporation tray. It is conceivable that the fan or the fan module is attached to the evaporation tray or screwed to it. Also not a positioning but near the evaporation tray is included with the invention. It is also conceivable to integrate the fan or the fan module or the receptacles for these components in the evaporation tray.
  • the refrigerator and / or freezer has at least one refrigerant circuit with at least one condenser and with at least one compressor, wherein the condenser is arranged on the rear wall of the device.
  • the condenser is arranged on the rear wall of the device.
  • the device with the exception, if appropriate, of the fan module has no duct system for guiding air over the evaporation tray.
  • a complex duct system for air guidance over components of the refrigerant circuit as is known in base units, is not present.
  • Sufficient is an air duct over the evaporation tray, which can be achieved with relatively small air flow channels.
  • the targeted air flow to the evaporation tray leads to an increase of the evaporation performance and preferably by the fact that transported by the air flow, the water vapor-laden air above the evaporation tray and the fresh air is replaced with higher moisture absorption capacity that the water is moved in the evaporation tray and thereby a uniform heat distribution in the volume of water is achieved, that the water is moved in the condensate tank and thereby an increase in the for Evaporation relevant water surface is achieved and that an increased evaporation performance is achieved by the moving air.
  • Another efficiency-increasing measure of the fan module or fan according to the invention is the resulting evaporative cooling, which cools the compressor.
  • the exhaust air flow can be directed to increase efficiency over the condenser.
  • energy-neutral use is conceivable.
  • the fan or the fan module as a whole is flexible relative to the evaporation tray, that is, in different positions and / or in different orientations mountable or parts of this.
  • a nozzle of the fan module is connected to the fan with an elastic connecting hose. This allows an adaptation of the fan unit to the installation situation z. B. in the compressor table, in the device base, in the ceiling unit, etc. make.
  • a flexible arrangement of elements of the fan unit can be achieved by means of flexible, rotatable, displaceable tube and hose connections, etc. Through these connections, a versatile mounting option of the fan unit is possible, thus optimizing the evaporation performance.
  • the motor of the fan is preferably arranged such that it is acoustically optimally arranged in the fan module, so that the least possible noise creates.
  • the fan is in communication with a control unit which controls or regulates its operation, wherein the control or regulating unit is designed such that the fan in continuous operation or synchronously to the compressor Refrigerant circuit is operated. It is also encompassed by the invention to operate the fan in dependence on one or more parameters, such as, for example, depending on how high the water level in the evaporation tray is. Further parameters are, for example, the ambient temperature, the ambient humidity, the number and / or duration of door openings ("door” means any closure element), the controller position for setting the temperature setpoint in the cooled interior, the duty cycle of the compressor, etc ..
  • a radial, axial, diagonal and cross-flow fan can be used.
  • the fan is designed such that it is operated with mains voltage. It is also conceivable to supply the fan with safety extra-low voltage. Furthermore, it is conceivable to carry out the fan with a power supply which has a relatively low power and size and may optionally be integrated into the fan unit. The power supply for this power supply can be tapped from the appliance supply of the refrigerator and / or freezer or from the compressor feed. Such a fan module allows, for example, retrofitting in case of service.
  • the fan or the fan module are designed as a retrofit, which brings cost advantages for devices with it, in which such an arrangement is not required.
  • the single figure shows a view of the compressor table of a refrigerator and / or freezer according to the invention.
  • Reference numeral 10 denotes a fan which serves to generate an air flow over the surface of the condensation water in the evaporation tray 20.
  • the reference numeral 30 denotes the compressor of the refrigerant circuit. Above the arrangement of compartment 30 and evaporation tray 20 is located on the rear wall of the device, the condenser.
  • the fan 10 is part of a fan module, which consists on the one hand of the fan 10 and a supply air duct 10 'and on the other hand of a duct system or duct system 40, which is arranged downstream of the fan 10.
  • this channel system 40 is designed such that it is adjustable in the vertical direction and also in the horizontal direction. This adjustability can be achieved for example by telescoping or rotatable channel segments. The adjustability may relate to the length, width and / or orientation of the channel.
  • the fan module is in direct contact with the evaporation tray 20 and is associated with only this. This means that the air flow generated by the fan is guided by the fan exclusively to the evaporation tray 20 or to the condensation water therein. It can lead from there to other components, such as the condenser. This distinguishes the present invention from known solutions in which a fan is provided, which flows first to a condenser and then an evaporation tray.
  • the compressor table is also designed according to the figure, but without the fan module.
  • an evaporation must take place solely due to the waste heat of the compressor 30. Since, as stated above, due to the increased efficiency of the compressors only a small amount of waste heat is obtained, the evaporation performance can be significantly improved by an active air flow by means of the fan 10 or by means of the fan module.
