Cold water introduced into the wash vessel in the third wash cycle from the second cold water vessel is then preferably returned to the second cold water vessel after the third wash cycle.It can be provided with further advantage that the wash container comprises water nozzles for introducing cold water from the first cold water container and / or hot water from the hot water container and / or cold water from the second cold water container.It can be provided with further advantage that the first cold water container has a capacity between 20 I and 80 I, preferably between 40 I and 60 I, more preferably 50 I, and / or that the hot water container has a capacity between 2 I and 8 I, preferably between 4 I and 6 I, more preferably 5 I, and / or that the second cold water container has a capacity between 1 I and 3 I, preferably between 1.5 I and 2.5 I, more preferably 2 I.Furthermore, it can preferably be provided that cleaning elements for the mechanical cleaning of washware are arranged in the wash container, wherein the cleaning elements preferably have a diameter of between 0.5 cm and 2.0 cm, more preferably between 0.8 cm and 1.2 cm, in particular preferably of 1 cm.The cleaning elements can be designed in particular as cleaning balls or plastic balls.The cleaning elements achieve a mechanical cleaning of the washware. The cleaning elements drive in the water during the wash cycles and are constantly guided past the washware owing to the washware movement caused by the rotation of the washware basket.It is preferably provided that the wash container comprises an insulation, in particular preferably a vacuum insulation.By providing the vacuum insulation, heat loss due to radiation can be reduced. This increases the energy efficiency of the dishwasher.It can be provided with further advantage that the wash container comprises a high-frequency oscillator, wherein ultrasonic waves can be generated in water arranged in the wash container by means of the high-frequency oscillator.By means of the high-frequency oscillators, the cold or hot water located in the wash container can be excited with ultrasound in at least one wash cycle, preferably in the first wash cycle or in the second wash cycle. During the first wash cycle and / or during the second wash cycle, the cold or hot water introduced into the wash container collects in the wash container. By the operation of the high-frequency oscillators, the wash container becomes the vibration tank. The high frequency oscillations are transmitted to the water in the wash tub, whereby cavitation bubbles form within the water. As a result of the implosion of the cavitation bubbles, food residue or dirt is effectively removed from the washware. Meanwhile, the basket may continue to be rotated by the cold and / or hot water in the tub.It can be provided with further advantage that the wash container comprises at least one UV light source.By using UV light from the UV light source, the washware can be cleaned from bacteria and / or viruses. In this case, it can preferably be provided that the UV light is switched on during the entire operation of the dishwasher.In addition, it can be provided that the air inlet means is an inlet valve and that the air outlet means is an outlet valve.By means of the air inlet means provided in the wash tub and the air outlet means, an air exchange can take place within the wash tub after completion of the wash cycles, whereby the washware located in the wash basket and in the wash tub is dried more quickly.During the air exchange, it can be provided that the basket continues to rotate preferably at 90 revolutions per minute. By rotating the basket during the drying phase, the drying process is shortened tremendously.To accelerate the drying process, a suction pump can also be provided, with which the warm, moist air still located in the wash container after the termination of the first wash cycle and of the second wash cycle and of the third wash cycle, if provided, is suctioned off.According to the invention, it is provided that an air line connected to the first cold water container, in particular to a base of the first cold water container, is provided, wherein air removed from the wash container through the air outlet means can be conducted via the air line into the first cold water container.The warm air, which is preferably discharged from the wash container by means of the suction pump, is thus introduced into the first cold water container. The warm air introduced into the first cold water container from the wash container then rises from below in the first cold water container, cools in the process and releases the moisture absorbed therein to the water in the cold water container. From a corresponding outlet valve in the first cold water container, the dried and cooled air can then be discharged from the first cold water container into the ambient air.Preferably, a bottom of the wash container is formed with a slight inclination. As a result, flushing water from the flushing container can flow completely automatically out of the flushing container due to the gentle gradient.It can advantageously be provided that a dirt sensor is arranged in the first cold water container and / or in the hot water container and / or in the second cold water container, which sensor provides information about the water status.A further solution to the object underlying the invention consists in the provision of a method for cleaning washware, which can be carried out using a dishwasher as described above, wherein in a first wash cycle cold water is introduced, in particular sprayed, from the first cold water container into the wash container, wherein the wash basket is rotated in the wash container, and wherein in at least one second wash cycle hot water is introduced, in particular sprayed, from the hot water container into the wash container, wherein an air inlet valve and an air outlet valve are opened in the wash container, wherein warm and moist air is suctioned off from the wash container, and wherein the warm and moist air discharged from the wash container is introduced from below into the first cold water container via an air line.All features and functions explained in connection with the above-described dishwasher can accordingly also be transferred to the method according to the invention.Preceding the steps of the method according to the invention, the washware can first be inserted into the dishwasher rack. Further, a door of the dishwasher housing may be closed. In addition, the method steps according to the invention can be preceded by the activation of a UV light source in the wash container.In the first wash cycle according to the invention, cold water is introduced, in particular sprayed, from the first cold water container, preferably via water nozzles, into the wash container. The cold water can have a temperature of about 20° C. Preferably, the amount of cold water is 50 l. During the introduction of the cold water, the basket can rotate at 30 revolutions per minute. The cold water is preferably not discharged from the wash tub during the first wash cycle, so that after the entire contents of the first cold water tub have been introduced into the wash tub, all the cold water, for example 50 liters, is located in the wash tub. If the wash tub is completely filled with the cold water from the first cold water tub, the washware located in the wash tub is guided through the cold water by rotating the wash tub at preferably about 30 revolutions per minute. This achieves excellent coarse cleaning. Only a grease film can remain on the surface of the washware.This grease film is removed in the subsequent second rinsing cycle by introducing, preferably spraying, the hot water from the hot water container into the rinsing container. When the hot water is sprayed in from the hot water container in the second rinsing cycle, the basket preferably also rotates at 30 revolutions per minute. The hot water may have a temperature of approximately 85° C. at the beginning. The amount of hot water may be about 5 l. The hot water sprayed in effectively removes any grease film remaining after the first wash cycle from the washware. During the second wash cycle, the hot water may cool somewhat.It is preferably provided that after completion of the first wash cycle, the cold water is pumped out of the wash container and cleaned and / or filtered and is returned to the first cold water container.By pumping out and cleaning or filtering the cold water of the first wash cycle and returning the cold water to the first cold water container, a large proportion of the water can be reused and the water requirement is reduced. During the pumping of the cold water out of the wash tub after the first wash cycle, the basket can continue to rotate at a speed of 30 revolutions per minute.Furthermore, it can be provided that the wash basket, after the cold water of the first wash cycle has been pumped out, is at 60 to 90 U / min for 15 seconds. This completely removes water and dirt residues due to centrifugal force. The second rinsing cycle can then begin.It is preferably provided that after the end of the second wash cycle, the water is pumped out of the wash container and purified and / or filtered and is returned to the hot water container.As already described with regard to the first rinsing cycle, the hot water can be pumped off again in the second rinsing cycle and cleaned via filters and returned to the hot water container. The hot water cooled during the cleaning is then optionally heated again in the hot water container. By recycling the hot water into the hot water container, the water requirement can be significantly reduced.Furthermore, it can preferably be provided that the second rinsing cycle is repeated at least twice, preferably at least three times, in particular preferably at least four times.The repeated execution of the second wash cycle makes particularly effective cleaning of the washware possible. Between the plurality of second wash cycles, the hot water is preferably filtered each time and returned to the hot water container. If the amount of water when the second wash cycle is carried out once is 5 l, then a total of 20 hot water is used when the second wash cycle is repeated four times. The initially preferably 85° C. hot water can cool to 65° C.Preferably, it can further be provided that after the at least one second rinsing cycle a third rinsing cycle is provided, in which a small amount of cold water, for example two liters, is introduced, in particular sprayed, from the at least one first cold water container or from the second cold water container into the rinsing container.The cold water of the third wash cycle can have a temperature of 20° C.In the third rinsing process, the cold water ensures that the interior of the wash tub and the washware cool and that water vapor condenses.Moreover, it can preferably be provided that the third flushing process is repeated at least twice, preferably at least three times, more preferably at least five times. During the third wash cycle, the wash basket can also rotate at 30 revolutions per minute.It is preferably provided that after completion of each execution of the third wash cycle, the cold water is pumped out of the wash container and cleaned and / or filtered and is returned to the first cold water container or the second cold water container. During the repeated execution of the third wash cycle, the temperature of the cold water may increase from 20° C. initially to 40° C.In particular, it can preferably be provided that after the end of the last execution of the third wash cycle, the cold water is pumped out of the wash container and cleaned and / or filtered and is returned to the first cold water container. In the third wash cycle ducts preceding the last duct of the third wash cycle, on the other hand, the cold water is pumped out of the wash container and purified and / or filtered and fed to the second cold water container.It can be provided with further advantage that after termination of the third wash cycle a predetermined amount, for example two liters, of the cold water is removed from the first cold water container and disposed of as waste water via a drain. It can then be provided that the quantity of cold water removed from the first cold water container is replaced from the second cold water container.The second cold water container is then filled again, for example via a house connection.In the method according to the invention, it is provided that an air inlet valve and an air outlet valve in the wash container is opened and that warm and moist air is suctioned out of the wash container, for example by operation of a suction pump. During this process, the wash basket can rotate at preferably at least 90 revolutions per minute. The warm and moist air removed from the wash container is introduced according to the invention via a corresponding air line from below into the first cold water container. The warm, moist air rises in the cold water container, cools down in the process and discharges the moisture contained therein to the cold water container. For pressure equalization, an air outlet valve can be provided in the first cold water container, by means of which air removed from the wash container and cooled and dried in the first cold water container can be discharged into the ambient air.It can preferably be provided that during the first wash cycle and / or the at least one second wash cycle and / or the third wash cycle, cleaning elements, in particular cleaning balls or plastic balls, are arranged in the wash container. By means of the cleaning elements, a mechanical cleaning of the washware is additionally effected.In addition, it can be provided that ultrasonic oscillations are induced in the water located in the wash container during the first wash cycle and / or the at least one second wash cycle and / or the third wash cycle.Furthermore, in one step of the method, it can be provided that the UV lamp is switched off after all the flushing operations have been carried out.Furthermore, in a short program, it can be provided that the first flushing process is omitted. The second rinsing cycle is thus started directly after the UV lamp is switched on.In an intensive program, it can be provided that the above-described method is carried out twice or more times.Furthermore, rinsing agents can be used in the first rinsing cycle and / or in the at least one second rinsing cycle and / or in the third rinsing cycle.Brief Description of the FiguresThe invention is explained in more detail below with reference to the attached figures. They show FIG. 1 is a side cross-sectional view of a dishwasher, FIG. 2 is a front view of the dishwasher, FIG. 3 is a side view of the dishwasher, FIG. 4 shows a line plan, and FIG. 5 shows a flow chart for a method for cleaning washware.DETAILED DESCRIPTION OF THE FIGURESIn the figures, identical or corresponding components are identified by the same reference numerals.FIG. 1 shows a dishwasher 100 according to the invention in a lateral cross-sectional view. FIG. 2 shows the dishwasher 100 in a front view. The dishwasher 100 comprises a housing 10. Within the wash tub 11 a wash basket 13 for receiving washware is rotatably arranged on a horizontally oriented shaft 12.

The tub 11 has a bottom floor 20 provided with a slope. As a result, water located in the wash container 11 can easily drain off.The dishwasher 100 comprises a first cold water container 21 as well as a second cold water container 22 and a hot water container 23 (FIG. 2 ). The rinsing container 11 further comprises water nozzles 44 by means of which cold or hot water can be sprayed from the first cold water container 21, the second cold water container 22 and the hot water container 23 into the rinsing container 11. In addition, a high-frequency oscillator 24 is provided in the wash container 11, with which high-frequency oscillator water located in the wash container 11 can be excited to ultrasonic oscillations. Furthermore, UV lamps 25 are provided in the rinsing container 11.FIG. 3 shows a further side view of the dishwasher 100 with the door 17 open. When the door 17 is open, the bearing 16 is no longer connected to the dishwasher basket 13. The horizontally oriented shaft 12 is designed as a telescopic shaft 26. Thus, by telescoping the telescopic shaft 26, the wash basket 13 can be moved out of the wash container 11 forward through the door 17 of the dishwasher 100 and can possibly even be removed there from the telescopic shaft 26. This facilitates filling of the wash basket 13.FIG. 4 shows a line plan for supplying water into the wash container 11. The first cold water circuit 27 is provided to supply cold water from the first cold water tank 21 to the wash tank 11 by means of a pump 30 shared by the first cold water circuit 27, the hot water circuit 28 and the second cold water circuit 29. By means of a first pump 31 of the first cold water circuit 27, the cold water is returned from the wash container 11 to the first cold water container 21. For cleaning the recirculated water, a first filter 32 is also arranged in the first cold water circuit 27. Analogously to the first cold water circuit 27, the hot water circuit 28 is designed to feed hot water from the first hot water container 23 to the wash container 11 by means of the shared pump 30. By means of a second pump 33 in the hot water circuit 28, the hot water from the wash container 11 is returned to the hot water container 23. A second filter 34 is arranged in the hot water circuit 28 for cleaning the recirculated water. The second cold water circuit 29 is in turn provided to supply cold water from the second cold water container 22 to the wash container 11 by means of the shared pump 30. By means of a third pump 35 in the second cold water circuit 29, the cold water is returned from the wash container 11 to the second cold water container 22. A third filter 36 is arranged in the second cold water circuit 29. Finally, the first cold water container 21 has an outflow 37. Via a water connection 38 with a water decalcifier 39, water can be supplied from a house connection 39 to the second cold water container 22. A replenishing pipe 40 is also provided between the common pump 30 and the second cold water tank 22, and a heating rod 45 for heating water therein is disposed in the hot water tank 23.The operation of the dishwasher 100 is explained in more detail with reference to the flow diagram according to FIG. 5 for a method 200 for cleaning washware.After filling the dishwasher basket 13 and closing the door 17, the UV lamps 25 are first switched on in a first method step S 1. Subsequently, in a second method step S 2, a first rinsing cycle is carried out. In the first rinsing cycle, cold water is conducted from the first cold water container 21 by means of the common pump 30 through the first cold water circuit 27 and the water nozzles 44 into the rinsing container 11. In this case, the wash basket 13 rotates at 30 revolutions / min. When all the water from the first cold water container 21 is in the rinsing container 11, the water is excited to ultrasonic oscillations by means of the high-frequency oscillators 24. In this case, the wash basket 13 rotates further at 30 revolutions / min. Subsequently, the water from the wash tub in the first cold water circuit 27 is returned to the first cold water tub 21 by means of the first pump 31 through the first filter 32. During this, the basket 13 continues to rotate at 30 revolutions / min.After the first wash cycle, the wash basket 13 rotates at 60 to 90 revolutions / min for 15 seconds in a third method step S 3. As a result, centrifugal force, water and dirt residues are completely removed from the washware.In a subsequent fourth method step S 4, a second rinsing cycle is carried out. In the second rinsing cycle, hot water is conducted from the hot water container 23 by means of the common pump 30 through the hot water circuit 28 and the water nozzles 44 into the rinsing container 11. In this case, the wash basket 13 rotates at 30 revolutions / min. Subsequently, the water from the wash tub 11 in the hot water circuit 28 is returned to the hot water tub 23 through the second filter 34 by the second pump 33. The second rinsing cycle is repeated a total of four times.In a fifth method step S 5, cold water is conducted in a third flushing cycle from the second cold water container 22 by means of the common pump 30 through the second cold water circuit 29 and the water nozzles 44 into the flushing container 11. In this case, the wash basket 13 rotates at 30 revolutions / min. In the third flushing cycle as well, the water from the flushing container is returned to the second cold water container 22 in the second cold water circuit 29 by means of the third pump 35 through the third filter 35. The cold water ensures in the third wash cycle that the washware cools down and water vapor condenses in the wash vessel 11. The third rinsing cycle is also repeated several times, for example five times. After the last execution of the third wash cycle, in a sixth method step S 6, a predetermined amount of water is discharged from the first cold water container 21 via the outflow 37. The amount of water drained from the second cold water container 22 is replaced via the refill line 40. The second cold water container 22 is filled again via the water connection 38.In a seventh method step S 7, an inlet valve 41 and an outlet valve 42 are opened in the wash container 11 (FIG. 4 ). By means of a suction pump, not shown, air is sucked out through the outlet valve 42 of the wash container 11 and is conducted via an air line 43 according to FIG. 4 into the first cold water container 21.
