Definitions

  • the invention relates to a water-conducting household appliance, in particular a dishwasher, with a treatment room, with a softening device for washing or rinsing liquid, which is associated with a regenerating device with a brine stock, and with a storage container, which is arranged to conduct heat to the treatment room and at least one liquor volume sums.
  • a dishwashing machine in which a storage container is disposed in heat-conducting relation to a treatment space.
  • a container may be filled with cold liquid (fresh water or softened softened water) and thereby assist in the condensation of warm moist air at the adjacent wall of the treatment room during a drying program section.
  • cold liquid fresh water or softened softened water
  • an energy saving can be achieved if the water from the container is used in a program section in which heated liquid is needed.
  • the water in the second program has the heat energy that it has stored from the first program when drying.
  • the water has room temperature, which is usually higher than the temperature of water that comes fresh from the line.
  • the water can also store heat energy to the end of water-bearing program sections.
  • the DE 39 30 835 A1 discloses a domestic appliance with a storage container having two partial storage container for storing a liquor volume and a partial storage container for storing a Regenerierwassermenge, each having separate discharge lines.
  • the invention thus raises the problem of further improving the function of the storage container in the case of a water-conducting household appliance of the type mentioned at the outset.
  • the storage container in addition to the liquor volume summarizes a Regeneriervolumen, which serves to generate the brine supply, the capacity of the container is increased. There is thus more cold water available for cooling a wall of the treatment room.
  • component costs for a separate container for receiving the Regeneriervolumens be saved. It is expedient if the liquor volume comprises at least a subset of the amount of liquid required in a water-conveying program section. The water can then continue to be used after the condensation has been assisted. Here, the heat energy absorbed by the stored water is used for the following rinsing process.
  • the storage container has a first outlet, via which it can be completely or at least approximately completely emptied.
  • the water stored in the entire storage container including both liquor volume and regeneration volume, can flow out through the first outlet and be supplied in particular approximately to the washing container.
  • a downstream outlet valve For emptying the storage container via the first outlet either a downstream outlet valve can be provided. If this is to be saved, the first spout can be formed by a siphon.
  • the storage container has a second outlet in addition to the first outlet, wherein only the regeneration volume can be emptied via the second outlet.
  • the amount of water necessary for brine production can be precisely metered without further measuring devices.
  • Such a method is much more accurate than the measurement of the amount of water entering the salt container through an impeller meter.
  • the storage container can be emptied at least approximately completely via the first outlet.
  • the storage tank can be filled with either soft water or fresh water. Both variants offer various advantages that can be found in the descriptions of the respective embodiments.
  • the storage container may be assigned a fill level sensor. This provides extra security if a commonly used water flow sensor is not working properly.
  • a circulation pump provided for circulating rinsing fluid is operated at an increasing speed during the emptying of the storage container. Since the emptying of the storage tank takes longer than the direct supply of fresh water into the treatment room, an extension of the program duration would be expected. This can be prevented if, already with the emptying of the storage container, the circulating pump begins to run at a low speed adapted to the liquid level in the treatment space, and then an increase in speed takes place.
  • the speed increase can be made level-controlled.
  • a pump with variable-speed drive is used in an advantageous manner. Then, the level of the collecting pot can be determined from the deviation of the drive and the speed can be increased adjusted.
  • a simple variant, which is suitable for a speed-controllable pump drive is characterized by a time-controlled speed increase. Suitable switch-on times and speed increases, linear or non-linear, can be determined in experiments.
  • first outlet flow is preceded by a sieve. This prevents lime from settling in the valves.
  • the regeneration volume is used both for regeneration and for the water inlet with the best possible support of the drying and storage and reuse of heat energy.
  • FIGS. 1 to 3 show different embodiments of an inventively designed household appliance using a dishwasher. Schematic diagrams constructed in the manner of a flow chart are shown with the components important for the water flow of the dishwasher.
  • Dishwasher 1 shown has a symbolized by a box wash chamber 2 as a treatment room.
  • a storage container 3 is arranged in a known manner. It is part of a symbolized by a dashed box water pocket 4.
  • Other integrated into the water pocket 4 components are a wellgelradprogressivelyer 5, four valves, namely a storage outlet valve 6, a changeover valve 7 for control the rinse water hardness (see EP 1 080 681 A2 ), another switching valve 8 and a regeneration valve 9, three water protection devices 10 to 12 and a resin container 13 of a softening device.
  • the water bag 4 is fluidly connected via the second water protection device 11 and the storage container 3 with the washing compartment 2.
  • Water protection devices are formed by free flow paths which comply with the regulations of the DVGW and are intended to prevent backwash of flushing fluid into the lines of the domestic water supply.
  • the connection via the second water protection device 11 opens into a Spülraumbelbyung 14 in the lower region of a Spülraumitwand 27.
  • the connection via the storage container 3 is a hose connection 15 and opens into a collecting pot 16, which closes the washing compartment 2 down.
  • the outlet 17 of the storage container 3 via the hose connection 15 can be controlled by the storage drain valve 6.
  • the storage container 3 is provided with an overflow 18, which also opens into the Spülraumbelpresentung 14 via a line 19 in the form of a hose connection or a channel.
  • the storage container 3 has a second outlet 20.
  • the regeneration 22 provides in this way a defined amount of water ready and can be supplied by a line 23 in the form of a hose connection or a channel a salt tank 24 a regenerating device.
  • the emptying of the regeneration volume 22 is controlled by the regeneration valve 9, which is connected downstream of the salt tank 24 in terms of flow.
  • the regeneration valve 9 When the regeneration valve 9 is open, the brine produced in the salt tank 24 flows through the resin tank 13, regenerates the ion exchange resin and flows via the second water protection device 11 into the collecting pot 16 and thus into the lower area of the flushing space 2.
  • the second changeover valve 8 has to open in position "1". Subsequently, the brine is flushed out of the ion exchange resin with water, this is the water inlet valve 25 is opened and both changeover valves 7 and 8 are in position "1".
  • the water inlet to the washing compartment 2 or to the storage tank 3 takes place from the domestic water supply via a water inlet valve 25. With an impeller 5, the accumulated amount of water is determined. It is followed by the first water protection device 10. Via the first change-over valve 7, the water is supplied either to the resin container 13 (position “1") or directly to the storage container 3 (position “2").
  • the second switching valve 8 directs the soft water softened either the collecting pot 16 (in position "1", on the second water protection device 11) or the storage tank 3 (in position "2", via the third water protection device 12).
  • the line 26 designed as a hose connection or channel can not be moved from the first switching valve 7 (position "2") to the third water protection device 12, but to the second water protection device 11 (not in the FIG. 1 shown).
  • the line 26 designed as a hose connection or channel can not be moved from the first switching valve 7 (position "2") to the third water protection device 12, but to the second water protection device 11 (not in the FIG. 1 shown).
  • the variant 1. filling the storage tank 3 with fresh water
  • the softened soft water is used to preserve the glass (very soft water dissolves calcium ions from the glass and makes it blind) a proportion of fresh water. This blending can be achieved by combining variants 1 and 2 or 3 and 4.
  • the storage tank 3 is filled at the beginning of a program section drying in a first program with cold water (soft water, fresh water or preferably blended soft water) to the overflow 18 and thus serves as a heat sink of the adjacent Spülrauminflammatorywand 27 for drying support. Since the drying performance is quite good with cold water, in this case can be dispensed with a fan drying and the electrical energy to drive the fan (not shown) can be saved. For devices with automatic door opening ( EP 1 733 675 A2 ) becomes worktop preheating But worktop ventilation still requires a blower, see also DE 10 2007 008 950 A1 ,
  • the water is then discharged from the storage tank 3 into the collecting pot 16. If the storage tank 3 summarizes only a subset of the required amount of water, the remainder is taken in directly via the water supply line.
  • the water supply line instead of cold water from the water pipe (according to standard 15 ° C) at least a partial amount of water is available, which has at least room temperature (according to standard 23 ° C). This increases the mixing temperature of the incoming water and it takes less time and energy to heat up to a certain temperature level.
  • intermediate rinses (about ⁇ 10 min) may alternatively be dispensed with the emptying and filling of the storage container 3 in the intermediate rinse, since the contact time and thus the heat transfer are not sufficient.
  • the stored water from the cleaning cycle then flows only at the beginning of the rinse cycle.
  • the regeneration of the ion exchange resin takes place when it is exhausted.
  • the exhaustion can be detected by a sensor (not shown) in the resin container 13 or calculated from the hardness set by the user and measured with the impeller 5 total water quantity.
  • the regeneration volume 22 is passed from the storage tank 3 of the amount of water filled in the program section drying in the salt container 24 via the second outlet, the further regeneration process is described above. After draining, the regeneration volume 22 can be replenished to further aid drying.
  • FIG. 2 shows an embodiment of a water bag 4, in which the storage drain valve 6 is saved.
  • the storage container 3 is equipped with a siphon 28 as the first outlet 17.
  • a level sensor 29 is required, which determines the complete filling of the storage container 3 to the maximum regeneration volume 22. If now the storage container 3 is filled via the regeneration volume 22 addition, the siphon makes for a complete emptying of the storage container 3 in the collecting pot 16. The overflow 18 must be above the working level of the siphon 28 here. It only serves as security when the siphon 28 is clogged.
  • Another change from the embodiment according to FIG. 1 is that here the line 26 from the first switching valve 7 (position "2") is not laid to the third water protection device 12, but to the second water protection device 11, as already described above. As a result, the washing compartment 2 can be filled directly with fresh water.
  • the storage tank 3 can be filled only with not softened fresh water from the domestic water supply. Furthermore, only water is introduced into the washing compartment 2, which was previously located in the storage tank 3. In this way, the two changeover valves 7 and 8 and the third water protection device 12 can be dispensed with.
  • the water from the overflow 18 of the storage container 3 can also be passed directly into the opening for flushing aeration chamber 14 here.
  • the level sensor 29 is present. This also senses the complete filling of the storage container 3 up to the maximum regeneration volume 22.
  • the storage container 3 is provided with a sieve 30 in the bottom area above the first outlet.
  • this screen 30 is formed in a V-shape, whereby a so-called Kalkgurhaltetasche 31 is formed, which is able to save the precipitated lime over the entire life of the device.
  • a so-called Kalkgurhaltetasche 31 is formed, which is able to save the precipitated lime over the entire life of the device.
  • bypass channels 32 and 33 are available, which allow even with a completely clogged sieve 30 an outflow from the storage tank 3.
  • the screen 30 is preferably removable and can then be cleaned.
  • the water inlet to the storage tank 3 takes place from the domestic water supply via the water inlet valve 25. With an impeller 5, the accumulated amount of water is determined. It is followed by the first water protection device 10. In the upper area is the overflow 18, by exceeding the maximum level, the Overflowing water over the Spülraumbeldesignung 14 flows into the washing compartment 2. In order to bring softened soft water into the collecting pot 16 of the washing compartment 2, the storage drain valve 6 is opened, in which case the water flows by gravity through the resin container 13 into the collecting pot 16. To empty the storage container 3, the storage drain valve 6 is opened and the storage contents (liquor volume 21 plus Regeneriervolumen 22) flows softened into the collecting pot. By refilling and emptying the storage container, the entire water intake can thus be done with soft water. If hard fresh water is to be added to protect the glass, the storage container 3 must first be filled and then overfilled. Then fresh water flows through the overflow 18 and the Spggraumbelpresentung 14 in the washing compartment. 2
  • the Regeneriervolumenen is diverted by opening the Regenerierventils 9 from the filled storage tank 3 and flows by gravity through the salt tank 24 and then as brine through the resin container 13. From there it is directed into the collecting pot 16.
  • the subsequent flushing of the resin container 13 takes place with the storage drain valve 6 open by opening the water inlet valve 25 via the impeller 5, the first water protection device 10 and the storage tank.
  • the entire soft water inlet via the storage tank 3 is significantly extended compared to a water inlet, in which as in FIG. 1 described, the washing compartment 2 is at least partially filled with standing under line pressure water.
  • Factors that affect the running time are in addition to the lack of pressure resistances of lines, valves and water softening device and the decreasing geodetic height of the water level in the tank 3. It is therefore desirable to keep the water level as long as possible at a high level, at least the last-mentioned influencing factor so far as possible to compensate.
  • the storage tank 3 is equipped with the level sensor 29.
  • the storage drain valve 6 is opened for a time in which only a fraction of the storage tank contents is emptied into the collecting pot 16, makes sense about 0.75 liters.
  • the necessary valve opening time can be determined in tests and stored in the device control, not shown.
  • the impeller 5 determines the replenished amount of water. If this does not match the desired .75 liters, the unit controller may correct the valve opening time for the next part emptying procedure.
  • the above-described partial emptying and refueling is continued until the desired total amount of water intake minus the storage tank total volume has run in. Subsequently, the storage drain valve 6 is opened until the storage tank 3 is completely empty.
