Definitions

  • the invention concerns a refrigeration and/or freezer system with at least two refrigeration and/or freezer units.
  • a refrigeration and/or freezer system has a common operating unit for at least the two refrigeration or freezer units.
  • a signal transmission device is provided for the transmission between the operating unit and at least two refrigeration or freezer units of signals to control said refrigeration and freezer units.
  • the individual units are free-standing and have their own individual electronics for controlling the unit in question. Only the operation is executed centrally, via an operating component.
  • the operating unit can be separate, and can be linked with the individual refrigeration and/or freezer units by means of appropriate signal transmission connections. However, it is particularly responsive and advantageous if the operating unit is integrated into one of the refrigeration and/or freezer units and the other units communicate with this equipment, which contains the operating unit, via signal transmission connections. In this way the first equipment unit can also be used separately and if appropriate can be expanded for use as a module by means of additional refrigeration and/or freezer units. Moreover, the integrated operating unit ensures a compact aesthetic appearance.
  • the individual refrigeration and/or freezer units can constitute different temperature areas of a cooling system.
  • the system can include one refrigeration unit and one freezer unit.
  • an ice-cube-maker can be provided for one of the units. Thanks to flexible design of the system, various combinations can be devised and can be optimally adjusted to individual needs and space availability. In this case only a single operating unit is necessary, with corresponding cost savings.
  • signals are transmitted via a bus system, e.g. on the basis of a modified I 2 C bus.
  • Signals can be transmitted via appropriate cables inserted into connectors or sockets in the individual units. This facilitates easy installation and connection. According to another embodiment, the necessary control signals are transmitted through a wireless connection.
  • connectors or sockets are provided on each individual unit to facilitate a signal transmission connection when the individual units are pushed together.
  • This space-saving embodiment is optically pleasing and easy to execute.
  • the bus system also serves to transmit additional data, e.g. data about the contents of the individual units and their cooling parameters. This makes it possible to read all parameters of the individual refrigeration units on the common operating unit. If, for example, a system for monitoring the contents of the individual units is provided, the content data can also be called up on the central operating unit.
  • Such systems include, for example, antennas integrated into the individual refrigeration units for the purpose of receiving signals from transponders attached to the stored items.
  • FIG. 1 A refrigeration and/or freezer system according to the invention, consisting of two units.
  • FIG. 1 shows a cooling center with, for example, a refrigeration unit 1 and a freezer unit 3 .
  • the two units have doors 9 and 11 , and each has its own power unit, which is not visible in the representation in FIG. 1, and which serves to create low temperatures in the unit in question.
  • An operating unit 7 having several operating elements and indicators, shown only schematically, is visible on refrigeration unit 1 .
  • Operating unit 7 is connected on the one hand with the control and power unit of refrigerator unit 1 for the purpose of their control. This is done inside the equipment and therefore is not visible in FIG. 1. Additionally, operating unit 7 is connected with connector 13 , which merely by way of example is shown in the lower rear of refrigeration unit 1 .
  • a signal transmission cable 5 is inserted into this connector; the other end of said signal transmission cable 5 is inserted into an appropriate connection unit of freezer unit 3 .
  • This signal transmission connection transmits signals from operating unit 7 via the connectors and the transmission cable 5 to the control unit or power unit of freezer unit 3 for the purpose of controlling freezer unit 3 .
  • the number 14 designates another connector for connecting additional devices that can then be operated via operating unit 7 .
  • the refrigeration and freezing unit is set up as follows. In the arrangement, the individual units 1 , 3 , are connected by means of cable connection 5 and connectors 13 . The connection is easy to execute, and can be done by the end user. Operating unit 7 can now operate refrigeration unit 1 and freezing unit 3 . The individual parameters of refrigeration unit I and freezing unit 3 , for example the temperature, can now be indicated on operating unit 7 . With appropriate operating components, the temperature in the two pieces of equipment can be adjusted.
  • the connectors 13 or plugs of the individual pieces of equipment are designed in such manner that when the individual units are pushed together directly a signal-transmission connection is created. Additionally, an appropriate connector is provided on one equipment unit, and an appropriate plug is provided on the other equipment unit, which said connector and plug can mutually correspond. This eliminates the direct for a direct connection with cable 5 . However, if the equipment units are to be used individually, they can also be connected by means of an appropriate cable connection.
  • the equipment units are in separate areas, they can also be connected by means of, for example, a local bus communication system or a radio module.
