Definitions

  • the invention relates to a cleaning machine according to the preamble of claim 1.
  • Such a cleaning machine is from the DE 44 38 036 C2 known.
  • Cleaning machines have a wet area, which is commonly referred to as a laundry room and one of them watertight separate dry area in which, inter alia, a mostly electronic control of the machine and other units, such as pumps, valves and the like, are.
  • a mostly electronic control of the machine and other units such as pumps, valves and the like
  • Rotating arms the rotation of which greatly influences the cleaning result, namely the fact whether cleaning fluid escapes from the rotating arms and thus the objects to be cleaned are uniformly sprayed.
  • rotating arms the rotation of which greatly influences the cleaning result, namely the fact whether cleaning fluid escapes from the rotating arms and thus the objects to be cleaned are uniformly sprayed.
  • the said DE 44 38 036 C2 to arrange the pivot bearing of the rotary arm with an axial extension in the wet area, the extension has a transmitting device (eg metal cams, resonant circuit, etc.), their signals with a receiving device (reed contact, proximity switch, Hall sensor, etc.) in the wet or dry area be sensed.
  • a transmitting device eg metal cams, resonant circuit, etc.
  • a receiving device reed contact, proximity switch, Hall sensor, etc.
  • the rotational speed of the rotary arm can be determined, however, there is a need to extend the rotary bearing of the rotary arm and provided with a transmitter in the wet area, which is expensive on the one hand and on the other hand increases the susceptibility of the monitoring device, since the transmitter in the wet area the Spülscheinfluß and is exposed to constant temperature changes.
  • the pressure sensor consists of a rubber-elastic membrane, which bulges when hitting a Spülwasserstrahls and actuates a switch.
  • the DE 197 32 856 C2 proposes in further development of this principle, to arrange the pressure sensor at the end of a funnel, in which the liquid jet enters during rotations of the rotary arm.
  • the DE 40 10 066 A1 proposes to apply different rotating arms of the cleaning machine with different water pressure, so that they are operated at different rotational speed. From this and from the rinsing liquid emerging from the rotating arms, different sounds are generated in each case, which lie in characteristic frequency ranges.
  • a microphone which is arranged outside the washroom, the noise generated on the washroom inner wall is first recorded and then screened with the aid of an electronic filter, the characteristic frequency ranges from the signal mixture. An analysis of the remaining signals allows conclusions about the rotational behavior of the rotating arms.
  • a fundamental problem with the Dreharmsearchüberwachung is that the rotary arms are not permanently mounted in the washing chamber in many cleaning machines, such as those used in particular for the cleaning of medical equipment, but are on washing inserts that are equipped with objects to be cleaned and in the Washing chamber of the machine can be used.
  • the pivot arms are in a different position.
  • the receiving devices such as pressure sensors, microphones or the like are arranged at a fixed predetermined position in or outside the washing chamber, which is in the Use of washing inserts, each with differently arranged rotating arms is not possible.
  • the object of the invention is therefore to improve the cleaning machine of the type mentioned in that monitoring of movements of aggregates is possible, even if they are arranged at different positions in the washing room of the cleaning machine.
  • the basic principle of the invention is to provide sensors for monitoring the movement of aggregates on the wash insert. This then results in the subsequent problem of transmission of the sensor signals from the respective washing insert for controlling the cleaning machine, which is located outside the washroom, ie from the wet area of the machine to the drying area.
  • a galvanic coupling between the sensors and an evaluation circuit through contacts, plugs, etc. is excluded due to the prevailing in the wash chamber moisture and temperature effects due to the high susceptibility to interference.
  • the invention therefore proposes a galvanically isolated coupling.
  • an electromagnetic coupling with two coils is used.
  • the primary coil is located outside the washroom in the dry area or in waterproof Execution in the washroom (wet area) and is connected to an oscillator.
  • the secondary coil is located on the washing insert in the wet area and is connected to one or more also arranged on the washing insert sensors.
  • the sensors are, for example, reed contacts, which are actuated by magnets attached to the units. Each time a magnet passes the reed contact, the reed switch intermittently closes and reopens, momentarily shorting the secondary coil. This acts on the primary coil back to the oscillator, thereby changing at least one of its parameters, such as frequency, current and / or voltage.
  • the change of these parameters is evaluated by an evaluation circuit to the effect that the number of closing or opening operations of the switches per unit time are determined.
  • the number of closing and opening operations depends on the number of units and their rotational speed, these values are each characteristic of individual washing inserts. When individual units are blocked or the speed is too low, the number of closing and opening operations of the switches drops below a predetermined threshold and an alarm is triggered.
  • sensors other types of sensors can be used, such as inductive or capacitive proximity switches, by which a parameter of the oscillator is changed.
  • the units or rotating arms usually rotate asynchronously to each other, so that only relatively rarely occur overlaps of pulses, that at the same time several switches open or close. From the total number of pulses can then determine whether one or more of the units or rotating arms do not rotate correctly. Any overlaps that may occur can be eliminated by a correction factor. Also exists the possibility for a larger number of aggregates or rotary arms to combine them into several groups, in which case each group is assigned a pair of coils and an oscillator. Of course, individual units, such as rotating arms, can be monitored.
  • the secondary coil is formed on the washing carrier by an additional capacitance to a series or parallel resonant circuit, which is in resonance with the frequency of the oscillator. As a result, the sensitivity is increased.
  • any rotational movements of rotating arms can be detected but any rotational movements of moving or rotating parts in the washroom, such as a rotating washing drum for cleaning medical hoses, as shown in DE 31 43 005 C2 is known.
  • any kind of opening or closing operations or pulses generated on the washing cartridge can be transferred to the controller of the machine.
  • Sensors can be pressure switches, flow meters, flow meters or the like.
  • an identification device for identifying the washing carrier, for example a magnetic reading device and a magnetic coding on the washing carrier. Since different washing carriers also have different numbers of rotating arms or rotating parts, this information is to be transmitted to the evaluation device, which takes this information into account in the evaluation.
  • the evaluation device preferably outputs an alarm signal when it is determined that one or more rotating arms are not rotating at the expected speed.
  • Fig. 1 Referenced.
  • rotary arms it is expressly understood that with the invention, the movement of any aggregates can be detected.
  • Such units may be: rotary arms, washing drums, pumps, flaps, valves, valves, moving into the washroom door handles or the like.
  • a washing insert 1 which is for example an insert basket, which is charged with objects to be cleaned and is inserted into a washroom of a cleaning machine, has a plurality of spray arms or rotating arms D1 ... Dn, which are rotatably mounted on one or more axes of rotation A.
  • These rotary arms have spray nozzles, not shown, from which cleaning liquid emerges under pressure in known manner, whereby the respective rotary arm is set in a rotary motion.
  • a magnet M1 ... Mn is attached to each rotary arm D1 ... Dn, which is associated with a reed switch K1 ... Kn.
  • a reed switch K1 ... Kn Each time one of the magnets M1 ... Mn is moved past the assigned reed switch K1 ... Kn, it switches over briefly. This switching should not be, for example, a brief closing followed by re-opening of the reed contact. Conversely, it is also conceivable that the reed contact is normally closed and briefly opens when passing the magnet. All reed contacts K1 ... Kn are connected in parallel and connected to a secondary coil L2.
  • the secondary coil L2 may be connected in parallel with a capacitor C1 or, alternatively, a capacitor C2 may be connected in series with a terminal of the secondary coil L1, thus forming a resonant circuit tuned to resonant frequency with an oscillator.
  • Each washing insert 1 additionally has a coding 2, for example in the form of a magnetic coding, wherein a reading device 3 is located inside the washroom into which the washing insert 1 is inserted, which reads the corresponding code and thus provides a signal for a washing insert identification which is supplied to a controller 6 of the cleaning machine.

Both coils L1 and L2 are thus components of a resonant circuit with the oscillator 4. Changes at least one of the switches K1 ... Kn its switching state, so it also affects the resonant circuit of oscillator 4 and primary coil L1.
  • the secondary coil L2 is shorted.
  • at least one parameter of said resonant circuit changes, for example its frequency and / or its power consumption or its current or its voltage.
  • This process can be detected by a frequency evaluation circuit 5 and reported to the controller 6 of the machine, which outputs an error signal at an output 6a or initiates a termination of the cleaning process.
