Definitions
- the invention relates to a circuit arrangement for operation an electrically controllable solenoid valve with at least one valve actuator that can be brought into two working positions, by adjusting each one to the respective working position Corresponding one charged with a flow medium Flow path is selectable.
- Circuit arrangements according to the preamble of the claim 1 are for example in refrigeration units with several compartments different temperature to control from there to Upcoming, bistable solenoid valves in use, based on which of a compressor in a refrigeration cycle generated refrigerant flow to the evaporators in the compartments different temperature depending on the cooling demand becomes.
- the valve actuator of the bistable Solenoid valve according to the refrigeration requirement from the storage compartments the refrigerator in one or the other working position emotional. This happens by the electromagnets on the valve actuator force exerted as a result of which the valve actuator in its locking position is accelerated, with the Closing process generates a clearly audible noise becomes.
- the invention has for its object to propose measures, which in a simple way a quiet Enable operation of an electrically controllable solenoid valve.
- Circuit arrangement has means by which the adjustment the valve actuator in the other working position following an application of at least the Solenoid valve formed section of the flow path flow medium present predominantly in liquid fractions he follows.
- the invention provides that the means for Acting on the section formed by the solenoid valve the flow path with liquid flow medium by a time delay in the adjustment of the valve actuator regarding an activation of the flow medium driving means is achieved.
- a time delay is particularly easy to generate, if after a further advantageous embodiment of the object the invention provides that the temporal Substantially delaying means is formed electromechanically trained timer.
- Such a timer is characterized by its robust Construction from.
- the invention provides that the time delay effective means by one of electronic components composite timer is formed.
- the magnitude of the time delay can can also be varied easily afterwards.
- such a timer is extremely inexpensive realizable.
- the invention provides that the temporal Delay is in the range between 30 s and 90 s.
- a time delay has proven to be particularly applicable result if according to a next advantageous embodiment the subject of the invention is provided that the temporal Delay is 60 s.
- the object of the invention is that for driving of the flow medium serving as a refrigerant compressor is trained.
- FIG. 1 shows a fridge-freezer combination 10, whose heat-insulating housing 11 two by one heat-insulating partition 12 thermally separated, arranged vertically one above the other and with separate Doors 13 and 14 have lockable storage compartments.
- the higher lying lockable with the door 13 Storage compartment designed as a cooling compartment 15, which with vertical Distances arranged one above the other, for parking of refrigerated serving stands 16 is equipped.
- the others arranged below the cooling compartment 15, by the latter storage compartment separated by the heat-insulating partition 12 is designed as a freezer compartment 17, which for Frozen food can be pulled out like a drawer 18 has.
- Both the refrigerator compartment 15 and the freezer compartment 17 is for Maintaining its intended storage room temperature equipped with evaporators, not shown, which integrated in a refrigeration circuit, also not shown are within which a the evaporator with liquid Refrigerant supplying compressor is arranged, which is operated intermittently, the inputs and Shutdown phases of the compressor from those in the storage compartments prevailing temperatures are dependent.
- evaporators not shown
- a the evaporator with liquid Refrigerant supplying compressor is arranged, which is operated intermittently, the inputs and Shutdown phases of the compressor from those in the storage compartments prevailing temperatures are dependent.
- the digital signal "A" present on the output side at the evaluation logic 19 represents the input signal for the circuit arrangement 30, which is equipped on the input side with two RC elements which serve to achieve different time periods. These are formed by two ohmic resistors 31 and 32 arranged in parallel with different resistance values and a common capacitor 33 connected in series, the resistor 32 equipped with the lower resistance value being preceded by a diode 34 which, with its cathode connection to the Resistor 32 is connected so that it takes place via the charging process of the capacitor 33 via the higher-resistance resistor 31.
- the voltage potential generated by the charging process on the capacitor 33 is connected to the merged inputs of a NAND gate 35, the output signal of which is fed to the base of a PNP transistor 36, the emitter connection of which is connected to a DC voltage supply "U B ", while its collector connection is connected via one of the Collector current-limiting ohmic resistor 37 is connected to ground potential.
- the gate connection for tapping the ignition current of a triac 38 is arranged, with its second main electrode connection a monostable coupled to the line pole "L" of a 230 volt AC voltage , two flow paths switching solenoid valve 39 is connected.
- the other main electrode connection of the triac 38 is connected to the zero pole "N" of the AC voltage supply, which at the same time also forms the ground connection for this main electrode of the triac 38.
- One for the cooling compartment 15 due to the increased therein Storage temperature existing cooling demand is at the exit the evaluation logic 19 by a logic one for the output signal "A" indicates which one is the activation of the refrigerant compressor and on the other hand one Switching process of the monostable solenoid valve 39 from its Rest position for changing the flow path for the Refrigerant to the evaporator of the refrigerator compartment 15 means.
- circuit arrangement 30 instead of the discrete electronic in the exemplary embodiment Components of circuit arrangement 30 it is also conceivable whose and the evaluation logic 19 underlying function by an appropriately programmed Microprocessor replicate, so that the time delayed start-up of the solenoid valve 39 with respect the compressor through an appropriate software program could be accomplished.
