Definitions
- the invention relates to an automatic washing machine and a method for operating an automatic washing machine.
- the invention relates to an automatic washing machine with a tub for holding water, a drum rotatably mounted in the tub for holding laundry, a loading opening for filling the drum with laundry and a door for closing the loading opening, which has a dispensing channel for accommodating detergent has, a motor for driving the drum and a control device which is designed and set up to control execution of a washing program, and a method for operating such an automatic washing machine.
- the invention therefore presents the problem of providing an automatic washing machine and a method for operating a washing machine with a detergent supply in the door of the washing machine, which are designed in such a way that access from the door to the drum can be exposed through adjacent items of laundry in order to supply the detergent into the drum in one flushing process.
- the advantages that can be achieved with the invention are that the detergent-water mixture enters the interior of the drum unhindered by spinning and/or spinning the laundry during the rinsing process. In addition, an even distribution of the detergent-water mixture over the laundry is achieved.
- the invention relates to washing machines
- Carrying out a washing program to control the motor in such a way that laundry in the drum is spun before and/or during a dispensing process in which the water is fed to the drum through the dispensing channel, and to control the dispensing process in such a way that the water Dispensing channel is supplied in such a way that the detergent is flushed into the drum.
- the laundry By specifically spinning the laundry before and/or during the rinsing process, the laundry is pressed against the inner wall of the drum. This creates a free space in the middle of the drum.
- the water is preferably fed into the door's induction channel. This means that the detergent in the dispenser channel is flushed effectively and evenly into the drum.
- the control device is preferably designed to spin the dry laundry before the dispensing process and then supply water to the drum through the dispensing channel along with detergent during the spin cycle.
- the induction channel is designed such that powdered detergent enters the drum exclusively or essentially exclusively when water is fed into the induction channel. That is, the induction channel is designed in such a way that the supply of detergent is prevented without additional water.
- the induction channel is shaped in such a way that it has a dispensing channel inlet, for example in the form of an inlet opening for filling the induction channel with detergent, and a dispensing channel outlet, for example in the form of an outlet opening for flushing the detergent into the drum.
- the exit opening has, for example, a narrow point and/or a ramp with a predetermined inclination and/or gradient, which is or are designed such that the detergent does not move or essentially does not move to the drum on its own.
- the control device controls the motor in such a way that it rotates the drum during the spin at an application speed or pressing speed at which the laundry rests on the drum or is pressed. This ensures that the induction channel access to the drum is exposed.
- the application speed is a speed of the drum, in which all items of laundry lie against the drum shell.
- the pressing speed is a speed of the drum at which all items of laundry are pressed onto the drum shell.
- the invention further relates to a method for operating an automatic washing machine with a tub for holding water, a drum rotatably mounted in the tub for holding laundry, a loading opening for filling the drum with laundry, a door for closing the loading opening, which has a dispensing channel for accommodating detergent, a motor for driving the drum, the method comprising carrying out a washing program which has a dispensing process for flushing the detergent housed in the dispensing channel into the drum, the laundry being spun before and/or during the dispensing process and during the dispensing process, water is supplied to the drum through the dispensing channel in order to flush the detergent from the dispensing channel into the drum.
- the drum is spun before the dispensing process and water is then supplied to the drum through the dispensing channel during the spin cycle in order to flush the detergent into the drum.
- the drum rotates during the spinning of the laundry at a contact speed or pressing speed at which the laundry rests on the drum or is pressed. This ensures that the induction channel access to the drum is exposed when the water is fed to it.
- the detergent is preferably in powder form. This prevents or at least reduces the risk of the detergent moving into the drum on its own.
- FIG. 1 shows a cross-sectional view of an automatic washing machine according to the invention before a dispensing process
- Fig. 2 is a cross-sectional view of the washing machine shown in Fig. 1 during the dispensing process.
- Fig. 1 shows a cross-sectional view of an automatic washing machine according to the invention before a dispensing process.
- the washing machine has a tub 1 for holding water 8, a drum 2 rotatably mounted in the tub 1 for holding laundry 6, a loading opening (not shown) for filling the drum 2 with laundry 6 and a door 4 for closing the loading opening on.
- the door 4 has a dispensing channel 5 for storing detergent 7.
- the induction channel 5 has an induction channel inlet 51 for filling the induction channel 5 with a detergent 7 and a Dispensing channel outlet 52, through which the detergent 7 can be flushed into the drum 2 while supplying water 8 into the drum 2.
- the washing machine has a motor (not shown) for driving the drum 2 and a control device (not shown) which is designed and set up to control the motor while carrying out a washing program in such a way that the laundry located in the drum 2 6 is spun before and/or during a dispensing process, and to control the dispensing process in such a way that the water 8 is fed to the dispensing channel 5 in such a way that the detergent 7 is flushed into the drum 2.
- the washing machine is shown before a dispensing process and in a state in which the laundry 6 is distributed in the drum 2 and blocks the dispensing channel exit 52.
- Laundry 6 is preferably spun before the rinsing process, but this is not shown in FIG.
- Fig. 2 shows a cross-sectional view of the washing machine shown in Fig. 1 during a dispensing process.
- the washing machine is shown during the dispensing process and in a state in which the laundry 6 is spun so that the laundry 6 is washed out by means of the
- Spinning rests on the drum 2 and the dispensing channel outlet 52 is exposed, and in which water 8 is fed to the dispensing channel 5 during the dispensing process in order to flush the detergent 7 from the dispensing channel 5 into the drum 2.
