- Figure 1 a schematic representation of a cleaning device according to the invention, to whose pressure line a spray nozzle is connected, and
- Figure 2 a schematic representation of the time course of the operating pressure of the cleaning device at different closing times of the spray nozzle.
- FIG. 1 shows schematically an inventive cleaning device in the form of a high-pressure cleaning device 10 is shown, which includes a high-pressure pump 12 which is driven by an electric motor 14. Via a suction line 16, the high pressure pump 12 cleaning liquid, preferably water, are supplied. The cleaning liquid is pressurized by the high-pressure pump 12 and discharged via a pressure line 18. To the pressure line 18 is connected via a high pressure hose 20, a spray nozzle in the form of a known per se and therefore only schematically shown in the drawing spray gun 22.
- the spray gun 22 comprises in the usual way a not shown in the drawing exhaust valve, the mit- Tels of a pivotable actuating lever 24 can be selectively opened and closed by the user.
- a signal generator in the form of a pressure switch 26 of the high-pressure cleaning device 10 is connected, which provides a control signal in response to the pressure prevailing in the pressure line 18 pressure.
- the electric motor 14 is associated with a control electronics 28, which is connected via a first power supply line 31 and a second power supply line 32 to the electric motor 14 and to which an electrical connection cable 34 is connected, which carries a connector 35 at its free end.
- the connection cable 34 can be connected in the usual way to a known per se and therefore only schematically shown in the drawing supply voltage terminal 37.
- a breaker switch 41 is connected, which is coupled to the pressure switch 26, so that in response to the control signals of the pressure switch 26 and consequently in dependence on the pressure prevailing in the pressure line 18 pressure of the cleaning liquid, the breaker switch 41 is opened and closed can.
- a current sensor 43 is also connected, which provides a sensor signal via a sensor line 44 of the control electronics 28, if it detects an interruption of the current flowing through the first power supply line 31 motor current.
- a main switch 46 is connected, which are operated manually by the user of the high-pressure cleaning device 10 can.
- an actuator in the form of a phase control 48 is connected, which can be provided by the control electronics 28 via a line 49, a control signal.
- the control electronics 28 comprises an evaluation unit 52, which is connected via the sensor line 44 to the current sensor 43 in connection.
- the control electronics 28 acipsprüftician 54 and a memory unit 56 and a control unit 58. The latter is in electrical connection with the evaluation unit 52, the voltage testing unit 54 and the memory unit 56 and is connected via the line 49 to the phase control 48.
- the voltage test unit 54 checks for the presence of an electrical supply voltage at the mains connections of the control electronics 28.
- the connection cable 34 is connected to the mains connections. If the connection plug 35 is connected to the supply voltage connection 37, then the electrical supply voltage is applied to the mains connections. This is detected by the voltage check unit 54, which then provides the control unit 58 with a corresponding signal.
- the high-pressure cleaning device 10 has various operating modes, which differ in each case by a different operating pressure of the cleaning liquid, which is supplied from the high-pressure pump 12 via the pressure line 18 of the spray gun 22.
- a different operating pressure of the cleaning liquid which is supplied from the high-pressure pump 12 via the pressure line 18 of the spray gun 22.
- To achieve the different operating pressures of the electric motor 14 can operate at different speeds.
- the adjustment of the rotational speeds takes place by means of the phase-angle control, which receives this via the line 49 from the control electronics 28, a corresponding control signal.
- the connecting cable 34 is connected to the supply voltage terminal 37 and the main switch 46 is turned on, then first the interlock switch 41 coupled to the pressure switch 26 closes and the electric motor 14 is started, so that the high-pressure pump 12 delivers cleaning fluid with maximum operating pressure via the spray gun 22 can be delivered. If the spray gun 22 is closed by the user, the pressure in the pressure line 18 briefly rises above the maximum pressure occurring during normal operation of the pump. This has the consequence that the pressure switch 26 provides the breaker switch 41 with a first control signal for opening, so that the connection of the electric motor 14 to the control electronics 28 via the first power supply line 31 is interrupted. The associated interruption of the motor current is detected by the current sensor 43, which then provides a corresponding sensor signal via the sensor line 44 of the evaluation unit 52.
- the pressure in the pressure line drops briefly below a predetermined minimum value. This has the consequence that a second control signal is output from the pressure switch 26 and then the breaker switch 41 again goes into its closed state and consequently the interruption of the motor current is canceled again.
- the duration of the motor current interruption detected by the current sensor 43 and consequently the duration of the time interval between the first and the second control signal is detected by the evaluation unit 52 and compared with a predetermined first period of one second. If the duration of the motor current interruption falls below the specified time, the evaluation unit 52 of the control unit 58 is a signal and this then changed the phase control 48 provided control signal. Instead of a control signal for full-phase opening of the phase control is then supplied to a control signal for a partial phase opening. This has the consequence that the electric motor 14 operates at a reduced speed and therefore the high-pressure pump 12 provides a reduced operating pressure.
- the respective operating pressure is stored in the memory unit 56, so that in the case of a subsequent renewed motor current interruption, the duration of which falls below the first predetermined time interval, the control unit 58 can transmit a further modified control signal to the phase detection controller 48, so that a further reduced operating pressure is established.
- the high-pressure cleaner 10 is operated at the same operating pressure that existed before the start of the motor current interruption by the corresponding operating pressure is retrieved from the memory unit 56.
- the voltage test unit 54 detects a failure of the supply voltage. This has the consequence that in a subsequent restart of the high-pressure cleaning device 10, the control unit 58 of the phase control 48 provides a control signal for a full-phase opening, so that sets the maximum operating pressure. The same applies if the user opens the main switch 46 for a time interval which exceeds a predetermined second time period of, for example, 20 minutes. If the cleaning device is switched on again after such a long interruption of the motor current, the control unit 58 also provides the phase angle control 48 with an actuating signal for a full-phase opening, so that the high-pressure pump 12 delivers cleaning fluid at maximum operating pressure.
- the switched-off high-pressure cleaning device 10 is connected to the supply voltage terminal 37.
- the main switch 46 is closed, then the high-pressure cleaning device 10 sets that operating. Since the connection plug 45 was disconnected from the supply voltage connection 37 before the time t 0 , the high-pressure pump 12 initially operates at the maximum operating pressure pi. If the user temporarily closes spray gun 22 at time ti and opens it again at time t 2 , the time interval ⁇ ti being shorter than the first predetermined period of one second, the operating pressure p 2 then automatically adjusts, for example, to a value of 80% of the maximum operating pressure pi may have.
- the high-pressure pump 12 operates again. changed at the operating pressure p 2 , which was present at time t 3 . If, at time t 5, the spray gun is closed and opened again at time t 6 , wherein the time interval .DELTA.t 3 is shorter than the first predetermined period of time, the power of the high-pressure cleaner 10 is changed again by adjusting the reduced operating pressure p 3 , its value For example, 60% of the maximum operating pressure can be.
- the operation of the high-pressure cleaner 10 continues to operate at reduced operating pressure p 3 , which was present at time t 7 . If, at time t 9, the spray gun is closed briefly and opened again at time tio, the time interval At 5 being shorter than the first predetermined period of time, then the high-pressure cleaning appliance automatically switches to an operating mode in which the maximum operating pressure pi again sets until at the time t u, the spray gun 22 is closed for a longer period.
- the operating pressure of the Hoch horrikisg ⁇ rätes 10 can be changed easily in a predetermined order, starting from the maximum operating pressure pi, which may be, for example, 100 bar, after a first short-term motor current interruption a reduced operating pressure p 2, for example, 80 bar and a further short-term motor current interruption, a reduced operating pressure with a value of, for example, 60 bar. Then the high-pressure cleaner goes 10 at a renewed brief interruption of the motor current automatically back to the operating mode with maximum operating pressure pi via. A transition to a changed operating pressure, however, takes place only when the duration of the motor current interruption falls below the first predetermined time period of, for example, one second.
- the operating pressure prevailing at the beginning of the motor power interruption resets if the interruption of the motor current did not last longer than a second predetermined period of time. If, however, the duration of the motor current interruption exceeds the second predetermined time period of, for example, 20 minutes, or if the connection plug 35 is disconnected from the supply voltage connection 37, then the maximum operating pressure pi is automatically restored when the high-pressure cleaning device is started up again.
