Definitions
- the invention relates to a method for washing laundry in a program-controlled drum washing machine, which is provided with connections for cold and hot domestic water of a household.
- Drum washing machines with connections for cold and warm fresh water are known (DE-C 853 151).
- the washing processes taking place do not differ from washing processes that are used in drum washing machines that are only equipped with a cold water connection.
- the laundry care specialist is required to set up a program section for washing normally soiled laundry, in which only fresh or only warm fresh water is used instead of cold so that the total washing time during this program section is approximately as long as for a corresponding program section with only cold fresh water.
- this specialist will compensate for the time lost here by extending the active washing time, which counts from the time the washing temperature is reached to the end of the program section, so that the time factor is not neglected and leads to a disruption of the leads the optimum described by Sinner's circle.
- the invention has for its object to develop a washing process mentioned at the outset which further increases the energy-saving effect which can be achieved by a shortened heating-up phase and which leads to a shortening of the overall duration of a washing program.
- the results regarding cleaning effect, bleaching intensity and gentle washing should be achieved, if not exceeded, as far as possible compared to those program sections in which only cold fresh water runs in.
- this object is achieved in that, in the case of a program section for normally soiled laundry in which hot domestic water is flowing in, in comparison to such a program section in which only cold domestic water is running in, the active washing time after reaching the desired washing temperature of the alkali is only approx. 0 is up to 40%.
- the heating-up time is approximately 40 minutes when the washing machine is fully loaded. This is usually followed by an active washing time of 20 minutes.
- the total time of this program section is therefore approx. 1 hour.
- the person skilled in the art would also observe this total time in the case of a program section in which hot domestic water is supplied, that is to say which is initiated at a higher initial temperature of approximately 50 ° C.
- the heating-up time for this example is only about 20 minutes.
- the active washing time is shortened according to the method according to the invention. For example, it is now only 0 to 8 minutes (corresponding to 0 to 40% of usually 20 minutes). The total time is now only 25 minutes: a reduction of almost 60%. During this short time, of course, less heat is lost through radiation and transition to the environment, so that another energy-saving effect can be seen.
- the loss of mechanical action on the laundry in the program section in which warm process water flows in, as a result of a shorter washing time compared to such a program section in which only cold process water runs in, can be at least partially compensated for in an advantageous development of the method according to the invention by intensifying the rhythm of movement. This means that the results regarding cleaning effectiveness and bleaching intensity can be adapted to the respective requirements.
- the method according to the invention can be carried out in a drum-type washing machine which contains a program control device with a switching stage which, when the desired washing temperature is reached, emits an output signal to the set input of a time control stage for the active washing process, the one time-out signal output of which is connected to an advance stage of the program control unit.
- the switching stage can be activated by a step-up device and, when the desired washing temperature is reached, starts a timing stage, the output of which changes when the signal changes after a certain time, e.g. B. 4 min, the activity of this switching stage ends for the active washing process.
- the program control device contains a further switching stage which can be switched on the output side to a changeover input of a clock generator for the movement rhythm when the hot water flow has ended and the desired washing temperature has been reached.
- a further switching stage which can be switched on the output side to a changeover input of a clock generator for the movement rhythm when the hot water flow has ended and the desired washing temperature has been reached.
- the program control unit can furthermore contain a switching stage which is connected to a switch for a magnetic valve controlling the flow of the hot domestic water or a further switching stage which is connected to a switch for a heating device which heats the washing liquor.
- a switching stage which is connected to a switch for a magnetic valve controlling the flow of the hot domestic water
- a further switching stage which is connected to a switch for a heating device which heats the washing liquor.
- the unfilled diagram line in FIG. 1 shows from 0 to 40 minutes, calculated from the beginning of the program section intended for a rinse cycle, the heating phase in a program section in which only cold process water that has an initial temperature of 15 ° C. is supplied. After the continuous heating process has ended, the wash liquor has a temperature of 90 ° C as a prerequisite. This is followed by a 20-minute active washing time, so that this program section ends after a total of 60 minutes and ends with the gradual inflow of cold water and cooling of the washing liquor.
- the filled diagram line shows the time course of the temperature in the washing method according to the invention in the program section for normally soiled laundry, in which warm process water flows in.
- the heating phase begins, the course of which is essentially parallel to the course of heating up cold water.
- the heating-up phase has ended and a washing temperature of 90 ° C has been reached. This is followed by an active washing time of about 5 minutes, so that after a total washing time of 25 minutes within this program section, the clear wash cycle ends.
- FIG. 2 shows part of a block diagram for a program control device which is provided in an automatically operating drum washing machine and which controls the washing method in accordance with the invention. It contains switching stages 1, 2 and 3, which can activate switching stages 11, 12 and 13 one after the other. The output of the switching stage 11 controls the flip-flop 21 in a position in which it switches on the solenoid valve 30 connected to its output 210. This solenoid valve controls the hot water flow in line 31.
- the switching stage 12 controls the bistable flip-flop 22 in a position in which its output 220 switches on the contactor 40 for the caustic heater 41.
- the inflow line 31 opens into the tub 50. Furthermore, a water level sensor 51 and a temperature sensor 52 are arranged in the tub, the switches 53 and 54 of which emit suitable signals to the switching stage 13.
- the switching stage 13 outputs its output signal to the set input of a timing stage 23, one output of which is connected to the sliding input of the advance stages 1 to 3.
- the output signal of the switching stage 13 is dependent on the signal of the switches 53 and 54.
- the switch 53 is also connected to the reset input of the bistable multivibrator 21, which switches off the solenoid valve 30 again when the switch is reset.
- the switch 54 is also connected to the reset input of the bistable multivibrator 22, which switches off the heating contactor 40 when the switch is reset.
