Definitions

  • the invention is based on an optical display and function control unit according to the preamble of the main claim.
  • optical dust detection means namely a light transmitter in the form of a light-emitting diode LED and a light receiver, such as a photo transistor, in which the dust, solid particles and the like sucked in.
  • optical indicator lights are driven, which are then designed such that, for example, practically no dust is a green Light-emitting diode can light up while dust, solid particles and the like passing through the suction channel. a red LED lights up.
  • the known device works with an amplifier means for the delay element connected downstream of the phototransistor, which is triggered in each case in the event of dust accumulation, for example can be a monoflop and then remains in its unstable state for a predetermined period of time, for example two or three seconds, in which approximately one red LED lights up and indicates a corresponding amount of dust.
  • the service life of the monoflop expires and the output switches to a green LED display, so that the user of the vacuum cleaner can then turn to another area, e.g. a carpet. In this way it is ensured that cleaning is possible with low energy, cost and time expenditure, since floors are not processed unnecessarily and possibly with an increased degree of wear.
  • the invention has for its object to provide a visual display and function control unit for a vacuum cleaner, which can be independently and separately assigned to any vacuum cleaner, possibly also later, and which is capable of supplementing the two basic functions of the dust accumulation indicator to record and display a large number of other functions of the vacuum cleaner with the least effort, without it being necessary to manually switch on such a display and function control unit.
  • the invention solves this problem with the characterizing features of the main claim and has the advantage that an optical display and function control unit, preferably in the form of a closed block, is located at a clearly visible location in the suction area of the vacuum cleaner and can be arranged without the need for a network power supply that operates automatically in all its display and control functions and is capable of performing a variety of tasks.
  • the invention only requires two external sensors, namely the optical sensor group for detecting the accumulation of dust in the suction pipe area of the vacuum cleaner and a mechanical pressure switch; only three different indicator lights are required for the display functions, the different functions and information of which can be easily evaluated by any user after a short period of familiarization.
  • optical display and function control unit All of these functions are made possible with the least means by the optical display and function control unit according to the invention, can be accommodated in the smallest space and can be implemented with only three optical indicator lights.
  • the supply battery is designated by 10; it is preferably a commercially available 9 volt block battery with a long service life and is connected to the positive supply line 11 via the pressure switch S.
  • the pressure switch is particularly finely adjustable and therefore in the Able to switch on the functional unit safely and to switch it off again when you have finished working with the vacuum cleaner, with a corresponding vacuum that can reach a pressure of around p ⁇ 50 mbar in a normal vacuum cleaner, e.g. a floor vacuum cleaner with an intake pipe and an empty dust bag.
  • the area 13 of the optical dust accumulation detection preferably consisting of a light-emitting diode D1 and a photo transistor T1 acting as a light receiver, then adjoins the area on-off switch as pressure switch S and supply battery.
  • the light emitted by the light emitting diode D1 then either hits reflecting dirt particles, dusts and the like. and then reaches the phototransistor as reflected scattered light or the dusts cause an interruption of the direct beam path in the suction channel of the vacuum cleaner, so that a corresponding reaction of the phototransistor T1 also takes place here.
  • An adjustable resistor R1 is also connected in series with the light-emitting diode D1; likewise, the phototransistor T1 is connected to the supply voltage via a resistor R2; its signal output is coupled via an interposed capacitor C1 to the inverting input of a downstream operational amplifier, the other input of which is supplied with a threshold value which can also be set, if desired, via the series connection of two resistors R3 and R4.
  • this area of dust accumulation evaluation and display is sufficiently and comprehensively described in the aforementioned DE-OS 34 31 164, so that a detailed explanation appears to be unnecessary.
  • the signal from the phototransistor T1 which responds to dust in the suction channel of the vacuum cleaner, reaches the trigger input 5 of a circuit after pulse formation and amplification first monoflops MF1, which is thereby triggered into its unstable state.
  • the monoflop MF1 can be connected from the outside and has at its connections 1 and 2 an RC element composed of a capacitor C2 and a resistor R9, so that its service life can be set.
  • the output is in the triggered state, for example 1 of the monoflop MF1 to low, so that any dust, solid particles, dusts and the like are present. indicating dirt diode S-LED1 lights up, for example in red color.
  • the dust sensors D1 and T1 no longer detect so much dust and solid particles that (repeated) triggering of the monoflop MF1 is possible via the control by the operational amplifier OP. This then tilts back to its normal state, its output Q1 goes low and the preferably green good light-emitting diode G-LED2 then lights up. This is a valuable indication for the user that there is now no more dirt in the previously worked area and the work can be continued in adjacent areas. So much for the basic function of the dust detection attack and the corresponding display via the diodes S-LED1 and G-LED2.
  • the monoflop MF1 is assigned a second time delay element in the form of a second monoflop MF2, whose monostable service life can be determined from the resistor R7 and the capacitor C3 via an external circuit.
  • the monoflop MF2 is also triggered by the output signal at the operational amplifier OP at its input 11. However, it can also be triggered by the output of the monoflop MF1.
  • the service life of the second monoflop MF2 is selected so that it is a multiple of the service life of the first monoflop; Expressed in numbers, for example, a delay time of about one to two seconds could be provided for the first monoflop, after which the switchover to the good light-emitting diode G-LED2 takes place and when dusts are no longer detected by the optical dust sensors.
  • the delay time for the second monoflop MF2 is approximately 30 seconds to 1 minute, these numbers, as is understood, are not to be regarded as limiting the invention.
  • MF2 has a further light-emitting diode via its output Q2, namely a so-called flashing light-emitting diode B-LED3 with supply voltage, so that this light-emitting diode, and for this purpose it is designed, in any case begins to flash at normal supply voltage.
  • MF2 has a further light-emitting diode via its output Q2, namely a so-called flashing light-emitting diode B-LED3 with supply voltage, so that this light-emitting diode, and for this purpose it is designed, in any case begins to flash at normal supply voltage.
  • a further control function results from these circumstances, which consists in that the state of exhaustion of the battery can be reliably detected.
  • the state of exhaustion of the battery With a gradual undervoltage in the battery, there is a gradually increasing insensitivity in the optical sensor area, so that the trigger pulses are also absent in this way and the second monoflop MF2 runs.
  • either the blinking light-emitting diode B-LED3 will also start to flash, or, when the voltage has dropped more, will light up constantly and thus inform the user that the Battery needs to be replaced.
  • Such flashing light-emitting diodes are commercially available and are able to work with a predetermined flashing frequency with sufficient supply voltage; If the voltage drops, the flashing frequency is reduced or the diode lights up without flashing.
  • the (red) dirt diode S-LED1 lights up for the duration of the service life of this monoflop, which of course then continues to light up when additional dust accumulation trigger pulses are received.
  • a further control function of the present invention consists in the fact that a reliable dust bag filling indicator is possible by utilizing the switching behavior of the vacuum switch S, which switches the multifunction unit of the present invention to the supply voltage of the battery 10.
  • This dust bag filling level display is made by off use of a combination of effects, which results from the fact that the vacuum switch S is initially able to switch on the unit at all by detecting a current operating state of the vacuum cleaner, namely the generation of the vacuum, and the fact that this vacuum is not constant, but rather of initially higher values (this is only to be understood relatively, the fluctuation range in the vacuum development is actually only in the range between about 15 to 50 mbar, so that the vacuum switch itself must be very sensitive and, above all, very easily adjustable) decreases to correspondingly lower values when the dust bag is empty, on the other hand but moreover, by working with the vacuum cleaner when pushing the brush back and forth over the material to be processed, vacuum fluctuations occur, which can be in the range of ⁇ 5 mbar, for example.
  • the pressure switch opens, the entire unit is switched off from its power supply and it goes out inevitably all display diodes, with the (red) dirt diode S-LED1 then lighting up again when the pressure switch closes again in this area.
  • the dust bag filling level approaches the exhaustion limit, then the dirt diode S-LED1 flashes.
  • the entire optical display and function control unit according to the invention for a vacuum cleaner can be easily accommodated in the smallest space, with the only requirement being that this be done adjacent to an area in which both the vacuum of the vacuum cleaner is detected and the optical dust accumulation sensor means are arranged in this way can respond to dust particles passing through the suction channel.
  • the easiest way to do this is, for example, in the form of the schematic representation of FIG.
  • a block B containing the circuit elements, the battery and the pressure switch which has connecting pieces S1, S2 on both sides, for example between the hose and Handle of a vacuum cleaner or to be interposed between the rigid pipe and the suction brush of such a vacuum cleaner, simply by plugging the short pipe sockets S1 and S2 on both sides onto the corresponding adjacent parts of the suction channel.
  • a function control unit then automatically switches on when the vacuum cleaner is put into operation and is able to inform the user of practically all the essential functions of the vacuum cleaner by means of the three different and preferably differently colored diodes.
  • the highly sensitive vacuum membrane switch shown in FIG. 3 comprises a cup-shaped first housing part 15a and a cover 15b.
  • the annularly raised wall region 16 of the housing pot has an inner annular groove 17 which, by means of a projecting shoulder, supports both the very thin, extremely flexible and slack membrane 18 in its edge region and the disk-shaped cover 15b, which has a central first connector 19 with a preferably stepped through hole 19a, which leads to one side of the membrane 18.
  • the dimensions of the cover 15b and the annular groove receiving and storing it are designed such that the cover 15b can be snapped under the action of force after inserting the membrane 18 into the annular groove 17, whereby both the cover is held firmly and immovably and at the same time the membrane 18 is on their edge area is clamped and stored.
  • a prestressing spring 21 presses against the contact plate and presses it upwards, with a further spring 22 being able to be arranged in an enlarged bore part 19b of the cover connector 19 in order to bring the membrane into a defined starting position.
  • the spring 21 simultaneously forms the electrical transmission means to a first contact connection 23, which can be designed as a contact pin 23 inserted or inserted into the bottom 24 of the housing pot 15a.
  • the contact pin touches at 25 the prestressing spring 21 which is in electrical connection with the contact plate 20 and thus forms a first connection, for example a soldering pin for the electrical switch thus formed.
  • the other pole is formed by a soldering lug 26, which can be arranged or can be an integral part of a metallic sleeve 27, which is inserted into a socket 28 projecting downward on the housing base and preferably consisting of an integral plastic.
  • the bushing 27 has an internal thread and receives a screw pin 29 which passes through the housing base with a perfect seal in the threaded region and is arranged with a contact tip 30 at a distance from the contact plate 20 driven by the membrane 18.
  • a connecting piece for supplying pressure or differential pressure is still indicated at 31 in the housing base.
  • the effective working distance between the contact plate 20 and the contact tip 30 can be adjusted and pre-adjusted with great precision, so that one Membrane switch is able to react with very high sensitivity and accuracy to very little pressure.
  • Overpressures, underpressures or differential pressures, depending on which connections, 19 or 31, the pneumatic functions to be detected are brought into effect.
