Definitions

the invention relates to a method for operating a washing machine with a housing and a tub disposed therein for receiving washing liquid for treating laundry, wherein a sensor arrangement for detecting a water level is disposed within the tub.
the laundry For washing laundry in a drum washing machine, the laundry is moved in the rotating drum, whereby the wetting of the laundry with the washing liquid and the washing mechanism are effected. In this case, there is water in the tub or in the drum, wherein the dirt is flushed out by the movement of the laundry.
the laundry After the washing and rinsing phases, the laundry is usually dewatered by a spin phase in which the drum is rotated at a speed at which the laundry rests against the drum shell and by centrifugal effect, the water from the laundry penetrates. For the proper operation of the washing machine, it is necessary that the machine is aligned exactly in the correct operating position.
the Panasonic National NA-VR 1100 as an alignment aid to a display means of a spirit level, a so-called “dragonfly", which is attached to the housing and must be considered by the user when setting up.
the known display which includes a bubble in a liquid, is not always clearly legible.
the handling when setting up is cumbersome, because on the one hand to make adjustments to the underside of the machine on the height-adjustable feet and on the other hand, the display means must be observed at the top.
the invention is therefore based on the object to provide a method that provides good assistance for the exact alignment of the washing machine in the operating position.
the main advantage of the method according to the invention is that with simple sensors in the washing machine, the orientation of the washing machine can be detected, so that the user is reliably informed on the basis of the detected position as soon as the machine has reached the exact operational installation position.
an initial program must be started, which constantly determines the position of the machine, while the user aligns the machine by changing the height-adjustable feet.
the sensor arrangement comprises at least two sensors, wherein a first sensor is mounted at a distance from a second sensor on or in the tub, wherein the predetermined amount of water is such that with exact alignment of the machine, both sensors just below the Water surface are located and protrudes at inadequate alignment of at least one of the sensors above the water surface. Due to the spaced arrangement an accurate detection of the always horizontally aligning water surface is possible with respect to the machine.
the sensor arrangement comprises four sensors which are each mounted at a distance from each other on or in the tub, wherein the predetermined amount of water is such that with exact alignment of the machine, all sensors are below the water surface and at least one inexact alignment Sensor is located above the water surface.
step c it is expedient to provide the message by means of a display or a light display in step c).
an already existing display can be used in the initial phase for the alignment.
the message is output in step c) by means of an acoustic output.
This can also be done in combination with the message on the display.
the user does not need to constantly watch the display as he makes adjustments to the bottom of the washing machine on his feet. Once the machine reaches the exact orientation, an audible signal, such as sound or sound, is emitted which the user can easily perceive.
step b) during the orientation of the machine, a continuous message to the user with directional information is provided as an indication of the orientation of the machine.
directional information can be different sounds or speech issues. So the user constantly hears on which foot he has to screw to reach the proper orientation of the washing machine.
the water can be used for machine cleaning or it is pumped out so that the machine is available for its intended use.
the invention further relates to a washing machine having a housing and a tub disposed therein for receiving washing liquid for treating laundry, a horizontally or inclined rotatably mounted drum in the tub, a motor for rotating the drum, a radiator, and a control device for controlling a selected Washing program, a sensor arrangement for detecting a water level within the tub, and further an output device for outputting messages to the user, wherein the control device is configured to determine an orientation of the machine in the operating position and a statement based on the determined result by means of Generate output device.
the control device which is advantageously a microprocessor with a Memory means and a computer program stored therein, programmed so that the method described above can be performed.
the sensor device comprises at least two sensors, wherein the first sensor is mounted on one side close to the tub bottom or on the tub bottom and the second sensor close to the tub cap or on the tub cap.
the sensors are mounted on the maximum possible distance from each other on or in the tub, whereby a very accurate detection of the position of the water surface relative to the tub is possible.
the sensor device comprises four sensors, the first sensor and the third sensor being mounted on one side close to the suds container cap or on the suds container cap, and the second sensor and the fourth sensor being close to the suds container bottom or on the suds container bottom, the first one Sensor to the third sensor and the second sensor to the fourth sensor are arranged spaced.
the sensors comprise electrodes or optical means for detecting the water surface. These sensors are very reliable and inexpensive to procure.
the output device is expedient to form the output device as a display or as a light indicator.
These types of displays are already present on most washing machines for the display of parameters or states anyway.
the output device comprises an acoustic output device, such as a loudspeaker.
the acoustic support facilitates the alignment process for the user or service person.
Fig. 1 is a purely schematic representation of a washing machine 1, shown with a tub 2.
the position and direction data relate to the operational installation position of the washing machine 1.
a rotatably mounted and driven by an electric motor 13 drum 3 is arranged, the laundry items located in a washing process in the tub 2 moves.
the drum 3 is made in the present embodiment of stainless steel and provided with a plurality of openings for the flooding.
the housing 4 has a loading opening 9, via which the interior of the drum 3 can be reached through the sealing sleeve 6.
the loading opening 9 can be closed by means of a door 5.
a radiator 7 is arranged, which can heat the washing liquid in the tub.
an inlet valve 15 is sketched, which provides the running in of the water from the supply network.
the water is passed through the connecting pipe 14 in the tub 2, wherein in the dispenser 11 entered detergent is flushed into the tub 2.
a drain device 12 is arranged, which leads the spent washing liquid or the rinse water from the tub 2 to the drain line 12c, which usually opens into a sewer.
the control device 18 controls the inlet valve 15, the activity of the drain device 12, the drive motor 13, which is energized via the power unit or a frequency converter 16, and the radiator 7th
Fig. 1 is also shown that the level of the washing liquid 19 is just below the drum 3, so that it does not come into contact with water. Furthermore, it can be seen that at the level G, the first sensor 17a and the second sensor 17b are located at or below the water surface 19, as occurs for an exact alignment of the machine in the upright installation position.
the signals detected by the two sensors are supplied to the control device 18, which determines the exact alignment on the basis of the sensor values and accordingly outputs a predetermined information to the user by means of an output device, in this case a display 18a.
an output device in this case a display 18a.
a pressure sensor 17b By means of a pressure sensor 17b, the water level and pressure fluctuations with moving drum is detected.
the intake valve 15 is controlled by the controller 18 in response to these detected values of the sensors 17a, 17b configured as level sensors and the pressure sensor 8.
Fig. 2 shows in a schematic view of the tub 2, are attached to the four sensors.
the sensors are each arranged at a distance from each other, so that an accurate detection of the horizontal water surface 19 is made possible almost at its outer contour 19a.
the above-mentioned method can also be used for level control for other phases of the washing process, for example for supplying the fresh water for the Washing phase or rinsing phase.
the method can also be used to accurately meter the amount of water for steam production.
