Definitions

  • the invention relates to refrigerated or deep-freeze furniture with electrical devices for carrying out various operating and monitoring functions.
  • Refrigerated cabinets which are composed of individual structural units (DE-PS 1 915 348). Each of these units has at least one electrical distributor, a lighting device, a temperature sensor for the room temperature in the refrigerator, an evaporator fan and a defrost heater.
  • a structural unit is used as a control unit and, as such, additionally has an electrical unit with a temperature signal amplifier, a power supply unit and a time switch and a further electrical unit which enables the mains connection to the electrical distributor and contains fuses and a warning system.
  • This arrangement makes it possible to connect the individual structural units to the control unit in a simple manner with plug connections, so that a rapid exchange of structural units can take place.
  • the invention is therefore based on the object of providing a reliable and safe control device which takes over all current and future control and monitoring tasks while at the same time reducing costs.
  • This object is achieved in that a central electronic control device is provided for controlling and monitoring the electrical devices.
  • an electronic control unit enables all operating and monitoring functions to be combined in one unit. This reduces the number of required components and thus the space required. In addition, the maintenance of a single device is easier to handle than the maintenance of a large number of components. After all, the use of a central electronic control unit leaves a lot of room for future further developments.
  • control device has a microprocessor as an essential component.
  • the electronic control unit has a memory, a data keyboard for temperature and time values, a function keyboard for various commands and a numerical display Data appear and after operating the function the keyboard automatically changes to the time.
  • the electronic control device has a 7-day time switch.
  • the electronic control unit is advantageously provided with an electronic control unit for comparison and processing of stored and measured data. It is also advantageous if the control device is equipped with network-synchronous actuators for switching power stages.
  • a central control unit can preferably be used for several refrigerators or freezers.
  • a microprocessor 1 is connected to a memory 2 and to a control unit 3.
  • the control unit 3 is connected to a data keyboard 4, a function keyboard 5, a numerical display 6 and a 7-day timer 7. Measured values pass through a line 8 into an analog-digital converter 9, which is also connected to the control unit 3.
  • the control unit 3 also has network-synchronous actuators, e.g. Relays for triacs, 10 in connection, which are supplied with voltage via a generator 11.
  • the microprocessor 1 is connected to a pulse shaper 12 which generates rectangular pulses for the time switch.
  • the function keyboard 5 has ten keys, eight of which are function keys for the various commands and two on and off keys.
  • the data keyboard 4 also consists of ten keys for entering temperature and time values.
  • the 7-day time switch 7 which can also be called a day switch, is automatically reset after a power failure; When starting up the control unit, the time switch only needs to be set once.
  • the numerical display 6 is switched over by the day switch 7. If no entry is made, the time is displayed continuously. During an entry, the entered data displayed. A short time after pressing the Enter function key, for example after 2 seconds, the display automatically jumps back to the time.
  • Entering data e.g. for setting the switch-off point (target temperature) of the room thermostat, press the function key for the corresponding command, e.g. Temperature key and subsequent data entry e.g. -20 ° C.
  • the entered temperature value then appears on the numerical display 6 and, if correctly entered, is confirmed by pressing the Enter key, i.e. transferred into the control unit 3 or into the memory 2.
  • a corresponding signal is sent via line 8 to the analog-digital converter and also to the control unit 3, where the measured temperature is compared with the stored temperature and, in the present case, the compressor switched on.
  • the switch-off temperature of the defrost thermostat is set to end the defrost.
  • the function keys time and temperature are pressed and the day switch 7 is set. Then 4 fixed temperature and time values, e.g. Entered at -20 ° C and 8:00 p.m. and pressed the Enter key. The values entered mean that the thermostat switches at -20 ° C during daytime operation Temperature increase is programmed.
  • buttons are used to switch the refrigeration unit lighting fixtures on and off at a specified time Time and On (or Off) pressed, the time value entered, the day switch set to the corresponding day and the Enter key pressed.
  • the warning temperature i.e. if, for example, the temperature in the refrigerator is too high, e.g. If a compressor is defective, the warning and temperature buttons are pressed, the warning temperature data is entered and the entry is pressed. If there is a temperature warning, this is indicated by a flashing symbol on the numerical display 6.
  • the switch-off temperature of the warning is permanently programmed. A sensor break or short circuit triggers a direct warning. At the same time, a relay contact is closed with which an external warning is activated.
  • the defrost data is programmed; No programming is required for dew point monitoring by the user.
  • the Cover and Time buttons are pressed, the corresponding time is entered and the Enter button is pressed.
  • the actuators are switched in synchronism with the zero crossing.
