Definitions
- the invention relates to an automatically controlled washing machine with a lye circulation system, at the bottom of a laundry treatment room by means of a Pump liquor discharged and via a pipe above that in the treatment room laundry is fed back to this, which washing machine further on a fresh water supply line is connected, which is opened by a valve or can be concluded by a to determine one in the conveying direction suitable pump device is controllable the existing volume flow.
- a washing machine is known from DE-A-43 32 225. With this washing machine is for constant flooding of the laundry in the washing drum a lye circulation system at the bottom of the tub using washing or rinsing water connected. This consists of a pipeline, in the course of which a drain pump and a sensor device are arranged.
- the sensor device Through the sensor device the presence of a flow in the pipeline is detected.
- the sensor device gives depending on the presence or absence of a flow in the Pipeline a corresponding signal to the arranged in the course of the fresh water supply Valve off, whereby either the fresh water supply is initiated or blocked becomes. In this way, the washing machine is always only with the absolutely necessary Amount of water supplied.
- the invention has for its object a washing machine of the type described Art in such a way that the control of the fresh water supply as possible sensor elements already present on the washing machine already take place anyway can.
- the object is achieved according to the invention in that in the course of Pipeline can be actuated by the volume flow prevailing in the pipeline Body is arranged, depending on the presence or absence of the volume flow protrudes into the measuring section of a turbidity sensor or this releases through which turbidity sensor the valve in its opening or Closed position is controlled.
- a simple mechanical one is required in the pipeline Part to be installed, whereas for the more complex sensory detection the turbidity sensor, which is available anyway for the turbidity measurement of the rinsing water is used.
- the body is a floating body formed and arranged in a vertical region of the pipeline With such an arrangement, the float takes its due to gravity Rest position automatically. There is therefore no need for separate funds for repatriation of the float in its rest position.
- a separate valve seat in the pipeline can be avoided by the peripheral edge of the valve plate has a conically increasing course and the pipeline at least in the area of the rest position of the float in the same way conical is progressive.
- the adjustment path of the float is also expedient in the pipeline limiting stop is provided, the position of which is selected so that when in contact of the float on the stop of the plunger the measuring section of the turbidity sensor fully releases.
- a washing drum 2 is rotatably mounted in the tub 1 of the washing machine. In it are laundry 3, which are lifted by the driver 4 when the drum 2 is rotated become and fall down again. This means that the Items of laundry instead, which means that they are always in new directions of washing or rinsing water be flooded.
- the wash or rinse water is supplied via a fresh water supply 5 and a detergent container 6 inserted into the tub 1.
- a valve 7 in the fresh water supply line 5 is used to control the fresh water supply
- valve 7 is controlled by a control device 8 of the washing machine controlled.
- a suds recirculation system For constant flooding of the laundry with washing or rinsing water is at the bottom of the Suds container 1 connected to a suds recirculation system.
- This consists of a Pipeline 9, in the course of which a drain pump 10, a heating device 11 and a Sensor device 12 are arranged.
- the sensor device 12 has one float 13 arranged in the pipeline 9.
- the float 13 is designed in the manner of a valve plate 15 provided with a tappet 14.
- the perimeter 16 of the valve plate 15 is designed to rise conically.
- the pipeline 9 is in at least in the area corresponding to the rest position of the float 13 in the same way conically rising. This allows the valve plate 15 in the rest position, i.e. in the absence of a volume flow in the pipeline 9 with its peripheral edge 16 snugly against the inner wall of the pipeline 9.
- a turbidity sensor 17 is attached to the outer circumference of the pipeline 9. At least in this area, the pipe 9 is made of translucent material, so that a from the transmission part of the turbidity sensor 17 emitted light beam 18, which is the measuring section of the turbidity sensor 17, through the pipeline 9 to the receiving part of the turbidity sensor 17 can reach.
- the diameter of the valve plate 15 is thus on the inside diameter of the pipeline 9 matched that the valve plate 15 in relation to the position of the measuring section of the turbidity sensor 17 so on the inner wall of the pipe 9 comes to rest that be Ram 14 still protrudes into the light beam 18 of the turbidity sensor 17 and interrupts it.
- a corresponding control signal can be sent from the turbidity sensor 17 to the Control device 8 are delivered through which the valve 7 from the control device 8 is controlled. Fresh water is thus supplied until the pump 10 Can pump water into the pipe 9.
- the volume flow set in the pipeline 9 lifts the valve plate 15 and pulls thereby the plunger 14 from the measuring section, i.e. from the light beam 18. Now the Light beam 18 onto the receiving part of the turbidity sensor 17 and triggers a control signal from which the valve 7 is blocked again.
- the washing machine is only the absolutely necessary amount of water supplied for a washing process.
- the turbidity sensor 17 already present in modern washing machines is thus in addition to measuring the turbidity during the washing process of the washing machine Control of the fresh water supply used.
- a separate sensor element can thus be used can be saved for the control of the fresh water supply.
