Definitions

  • the invention relates to a dishwasher, in particular a domestic dishwasher, with a washing compartment providing a washing area, which is used to hold items to be cleaned, and with a fresh water tank arranged as a side tank next to the washing compartment, which is fluidically connected to the washing compartment.
  • Known dishwashers have a washing compartment that provides a washing area. This is accessible on the user side via a loading opening, which can be closed in a fluid-tight manner by means of a pivotably mounted wash cabinet door.
  • the washing container is used to hold items to be cleaned, which can be, for example, dishes, cutlery and / or the like.
  • the dishwasher has a spray device in the interior of the washing compartment for the application of washing liquid to be cleaned, the so-called washing liquor.
  • This spray device typically provides rotatably mounted spray arms, two or three such spray arms being provided as a rule. When used as intended, the items to be cleaned are exposed to washing liquor by means of rotating spray arms.
  • the wash liquor released by a spray device during operation strikes the items to be cleaned and then collects in a collecting pot of the wash container.
  • the collecting pot is connected to a circulation pump on the one hand and a drain or sewage pump on the other hand.
  • the circulating pump which, when used as intended, circulates the washing liquid conveyed into the dishwasher is used to apply washing solution to the spray device.
  • the wash liquor is pumped out using the drain pump and discarded.
  • washing container which is typically taken from the public fresh water network.
  • the actual washing program begins and the circulating pump is started for the purpose of charging the spray device.
  • a wash program different program sections are run through, for example a pre-wash program, a cleaning program, an intermediate wash program, a final rinse program and / or the like.
  • the wash liquor is heated up.
  • appropriate heating devices are used which, depending on the initial temperature of the fresh water, require a correspondingly large amount of energy until the target temperature of the washing solution for the respective washing program section is reached. The heating energy required is greater, the greater the difference between the initial temperature of the fresh water and the target temperature desired for carrying out a wash program section.
  • a fresh water tank is known from the prior art, which is arranged on the outside of the washing compartment.
  • This fresh water tank is fluidically connected on the one hand to a fresh water line and on the other hand to the washing container. After a properly running wash program has ended, the fresh water tank is filled with fresh water from the fresh water line. This remains in the fresh water tank until the next wash program is carried out and is stored by this.
  • the next upcoming wash program is then carried out at least partially with fresh water preheated to room temperature, so that the temperature difference between the initial temperature of the fresh water introduced into the wash container and the target temperature to be reached for carrying out a wash program section is reduced, with the result that less heating energy is required.
  • the aim is to propose a heat recovery system that contributes more effectively to being able to save heating energy by extracting heat from used washing liquor for heating up fresh water.
  • the invention proposes a dishwasher of the generic type, which is characterized by a second fresh water tank, which is arranged as a base tank below the washing container, the first and second fresh water tanks being in fluidic connection, in which connection a pump is integrated is.
  • a second fresh water tank connected in parallel to the first fresh water tank is provided.
  • this is used to store fresh water. It is the purpose of both fresh water tanks to raise the fresh water stored therefrom to a higher temperature level so that, in contrast to the prior art, in the further course of a properly carried out washing process, less heating energy is required to achieve a washing liquor temperature that can be achieved for the respective washing process.
  • the advantage of the embodiment according to the invention is first of all that the amount of fresh water that can be stored is increased in contrast to the prior art.
  • the tank volume of the first fresh water tank and the second fresh water tank are preferably designed in combination in such a way that the amount of fresh water that can be stored is sufficient for the intended use Carrying out a rinsing process, no further fresh water is to be supplied to the rinsing process via a fresh water line during the rinsing process. Rather, the fresh water stored by the two fresh water tanks is sufficient to carry out an intended washing process, at least with regard to a cleaning program and / or a rinsing program.
  • the space available on the side of the washing compartment is not sufficient to provide a sufficient tank volume. It is therefore provided according to the invention to design the second fresh water tank as a base tank, that is to say to arrange it in the base area of the dishwasher below the washing compartment.
  • the base area of the dishwasher offers sufficient installation space to make the second fresh water tank so large in the tank volume that, in combination with the first fresh water tank, a sufficient amount of fresh water can be temporarily stored in the manner already described, so that the stored fresh water quantity is sufficient to be able to carry out a washing process as intended .
  • the first and the second fresh water tank are in flow communication.
  • a pipeline is provided which, starting from the first fresh water tank, leads to the second fresh water tank.
  • the second fresh water tank is filled with fresh water with the interposition of the first fresh water tank in that it is initially supplied with fresh water, which then overflows into the second fresh water tank via the fluidic connection. As soon as the second fresh water tank is filled with fresh water, the first fresh water tank is filled.
  • the two fresh water tanks are typically filled with fresh water after a properly carried out rinsing process has ended. This can then heat up to room temperature until the start of a subsequent rinsing process.
  • a further feature of the invention provides that a pump is integrated into the fluidic connection between the first fresh water tank and the second fresh water tank. This pump allows the fresh water stored in the two fresh water tanks to circulate between the fresh water tanks to let, that is to lead in circulation mode between the two fresh water tanks. This enables additional heat to be introduced into the fresh water, with the result that an even higher temperature level can be achieved with regard to the fresh water.
  • the fluidic connection between the first and second fresh water tanks has a flow circuit that is designed to be closed and has a feed line between the first and second fresh water tank on the one hand and a return line between the second and first fresh water tank on the other.
  • the pump provided according to the invention is preferably integrated into the return line.
  • circulated fresh water circulates in the flow circuit from fresh water tank to fresh water tank.
  • a pump in the feed line is not required because the second fresh water tank can be filled with the interposition of the first fresh water tank solely under the action of gravity. This is because the first fresh water tank, designed as a side tank, is arranged in the vertical direction above the second fresh water tank.
  • the pump integrated in the flow circuit from fresh water tank to fresh water tank is, according to a further feature of the invention, an axial pump or a radial pump in a vertical orientation.
  • This has the advantage of being able to arrange the second fresh water tank, designed as a base tank, comparatively deep in the base area of the dishwasher, so that the available space below the washing compartment can be used to the maximum. In this way, an optimized, large tank volume with regard to the second fresh water tank is made possible in an advantageous manner.
  • a heat exchanger is provided which is in fluidic connection with the washing container.
  • the heat exchanger can in particular be understood as a tank that can be filled with washing liquid or through which washing liquid can flow. When used as intended, the heat exchanger can be charged with washing liquor from the washing compartment. This enables heat to be transferred from hot rinsing liquor to fresh water.
  • the heat exchanger can over a washing liquor line is connected to the washing container, via which both the filling of the heat exchanger and the emptying of the heat exchanger back into the collecting pot take place.
  • a vent valve is opened which releases a vent line opening into the washing container and thus enables the heat exchanger to be filled via the wash liquor line, driven by gravity.
  • the vent valve is closed for a second heat exchange phase, in which part of the washing liquor is temporarily stored in the heat exchanger and the rest is pumped out.
  • the fluidic connection between the heat exchanger and the rinsing container has a flow circuit which is designed to be open and guided through the washing container, with a shut-off valve being provided both on the inlet side and on the outlet side of the heat exchanger.
  • washing liquor can be circulated through the flow circuit, namely starting from the washing container through the heat exchanger back to the washing container.
  • the shut-off valves provided on the inlet and outlet sides of the heat exchanger also make it possible to store rinsing liquor in the heat exchanger, if necessary, by closing the shut-off valves during a rinsing liquor circulation operation. The washing liquor stored in this way by the heat exchanger can still be used until it is pumped out to transfer residual heat contained therein to the fresh water carried in the other flow circuit.
  • the heat exchanger is arranged in the second fresh water tank.
  • the heat exchanger designed in particular as a tank, is therefore washed around by the fresh water when the fresh water is in circulation, so that the washing liquor located in the heat exchanger can transfer heat to the fresh water located in the second fresh water tank.
  • the configuration according to the invention allows two different procedures which can optionally also be combined with one another, which is preferred for reasons of maximized heat transfer.
  • a first method step after a cleaning program carried out as intended, the still hot washing liquor is passed through the heat exchanger guided. As a result, the fresh water in the second fresh water tank is heated. This circulation operation is maintained for a predefinable period of time. The washing liquor that is no longer required for the further washing process is then pumped out, but only in part. Part of the washing liquor that is no longer required remains in the heat exchanger.
  • the washing liquor remaining in the heat exchanger can still be used to additionally heat fresh water circulating in the second flow circuit.
  • this second method step can be carried out at the same time as the rinsing process being continued, that is to say it is not to be interrupted for a heat transfer from the rinsing solution to the fresh water. As soon as this second process step is also completed, the washing liquor stored by the heat exchanger can then be pumped out and discarded.
  • the heat exchanger is designed in a special way in order to optimize heat transfer from the washing liquor to the fresh water.
  • the design of the heat exchanger can be protected for itself.
  • the heat exchanger arranged in the second fresh water tank is designed as a fluid-tight container. Has passage openings through which circulated fresh water is passed when used as intended.
  • the container serving as a heat exchanger divides the volume space provided by the second fresh water tank into a first compartment and a second compartment.
  • the container serving as a heat exchanger is connected to the fresh water tank on the outer circumference in a fluid-tight manner. Filling the second fresh water tank with fresh water therefore means that fresh water is initially passed into the first, upper compartment of the fresh water tank in the vertical direction. From there, the fresh water flows through the passage openings into the second compartment. After passing through the second compartment, the flow circuit connecting the two fresh water tanks is followed by a return with the interposition of the first fresh water tank to the first compartment. In order to enable residue-free emptying of the fresh water tank, the bottom of the fresh water tank is aligned inclined towards its outlet.
  • two Opposite container sides in particular container sides lying one above the other, are brought together in sections and connected to one another with the respective formation of folds serving as channels, one connection point being equipped with at least one passage opening, in particular several or all connection points being equipped with at least one passage opening.
  • the advantage is achieved, on the one hand, that the tank volume provided by the second fresh water tank is maximized and, on the other hand, the heat transfer area provided by the container serving as a heat exchanger is also maximized.
  • the fresh water tank is preferably designed as an injection molded part. It has two half-parts that are connected to one another, for example by welding.
  • the container serving as a heat exchanger is preferably thin-walled in order to enable an optimized heat transfer between the washing solution and fresh water. It is therefore preferred to design the container as a blow molded part. In order to ensure a residue-free drainage of washing liquor, the container bottom of the heat exchanger is designed to be inclined towards a drain.
  • a further feature of the invention provides that the container has a circumferential seam which, in the final assembled state, is arranged circumferentially between the mutually facing edges of the two half-parts of the second fresh water tank. This construction ensures that, when used as intended, fresh water introduced into the first compartment of the fresh water tank can only get into the second compartment through the through openings provided for this purpose.
  • the above-described configuration of the heat exchanger is optimized overall to the extent that, on the one hand, there is an optimized heat exchange between the washing liquor to be discarded and fresh water, and on the other hand, a sufficient volume is made available by the second fresh water tank so that it can store so much fresh water that supplying fresh water that has not been preheated is avoided during the execution of a flushing process.
  • Fig. 17 shows a dishwasher 1 according to the prior art in a purely schematic representation.
  • the dishwasher 1 has a housing (not shown in greater detail in the figure) which, among other things, accommodates a washing container 2.
  • the washing compartment 2 in turn provides a washing area 3 which, when used as intended, serves to hold items to be cleaned.
  • a spray device 4 which is arranged inside the washing compartment 2, is used to load wash ware to be cleaned with wash liquor.
  • a spray device 4 preferably has spray arms 5, which are each rotatably arranged within the washing compartment 2.
  • the spray device 4 has a total of three spray arms 5, namely an upper spray arm, a middle spray arm and a lower spray arm.

  • the spray device 4 can be charged with rinsing liquor by means of the circulating pump 7, with either the upper and middle spray arm 5 or the lower spray arm 5 being charged with rinsing liquor depending on the position of the water diverter 8.
  • a waste water pump 12 is fluidically connected to the collecting pot 6, which pumps off the washing liquor located in the collecting vessel 6 if necessary and supplies it to the waste water line 13, as a result of which the washing liquor is discarded.
  • the dishwasher 1 is also connected to a fresh water line 14.
  • the fresh water line 14 is preceded by a water softener, which is not shown in more detail in the figure.
  • the fresh water line 14 opens into a switchover valve 15.
  • a feed line 16 and a tank line 18 are provided on the output side of the switchover valve 15. In this way, depending on the position of the switchover valve 15, either the supply line 16 or the tank line 18 can be served with fresh water.
  • the feed line 16 opens into the collecting pot 6.
  • fresh water therefore flows directly into the collecting pot 6 via the fresh water line 14, the switching valve 15 and the supply line 16.
  • the tank line 18 opens into a fresh water tank 17. This is typically arranged next to the washing container 2 and attached as a side tank to a side wall of the washing container 2.
  • the fresh water tank 17 is in fluidic connection with the supply line 16, specifically by means of a line 22 designed approximately as a pipe. This is fluidically connected to the fresh water tank 17 with the interposition of a valve 21 designed as a shut-off valve.
  • valve 21 If the valve 21 is in the blocking position, as shown in the figure, the line 22 is closed. According to this position of the shut-off valve 21, no fresh water stored by the fresh water tank can flow through the line 22 into the supply line 16. When the shut-off valve 21 is open, the Fresh water tank 17 stores fresh water through the line 22 and the supply line 16 into the collecting pot 6.
  • the fresh water tank 17 is also in fluidic connection with the washing space 3 provided by the washing container 2.
  • the fresh water tank 17 has an overflow 19, to which an overflow line 20 connects, which opens into the washing space 3. If the fresh water tank 17 is overfilled with fresh water, the latter reaches the washing chamber 3 via the overflow 19 and the overflow line 20.
  • the overflow line 20 also serves as a ventilation line for the fresh water tank 17.
  • the fresh water tank 17 is used to be filled with fresh water after completion of a properly run washing program.
  • the fresh water stored by the fresh water tank 17 can warm up to room temperature before the next wash program is carried out, so that the heating energy required in the subsequent wash program to heat the wash liquor is advantageously reduced.

  • the container forming the heat exchanger 24 has a circumferential seam 52 which, in the case of a container designed as a blow molded part, is a pinch seam.
  • the seam 52 is arranged circumferentially between the mutually facing edge edges 53 and 54 of the two half-parts 49 and 50.
  • the two half-parts 49 and 50 are welded along their mutually facing marginal edges 53 and 54 together with the interposed seam 52 of the container serving as a heat exchanger 24. There is thus a fluid-tight connection between the two half-parts 49 and 50, on the one hand, and a fluid-tight edge connection between the second fresh water tank 23 and the container serving as a heat exchanger 24.
  • Fig. 4 shows in this context an exemplary weld seam 55.
  • connection seam 56 As an alternative to welding, provision can also be made for a connection between the fresh water tank 23 and the heat exchanger 24 to be formed by means of a connection seam 56, as shown in FIG Fig. 5 is shown. It is preferred here to design the connecting seam 56 as an injection-molded seam.
  • Fig. 6 shows in a schematic representation the flow through the fresh water tank 23 with fresh water based on arrows 58 drawn in by way of example.
  • the fresh water is guided in the second flow circuit 26 and passes through the Inlet 43 into the fresh water tank 23. It flows through the first compartment 47 and then the second compartment 48 in the manner already described before it then returns to the pump 29 via the outlet 44.
  • the heat exchanger 24 housed therein is washed around by the fresh water.
  • the fresh water tank 23 has flow guide elements 57 on the inside.
  • the flow guide ribs 57 are integrated in the upper half part 49 and have the function of distributing the water as evenly as possible above the heat exchanger 24.
  • the bottom of the fresh water tank 23 is aligned inclined towards the outlet 44 at an angle ⁇ , which is in particular at least four degrees.
  • two feed lines 61 and 62 are also provided on the inlet side.
  • the inlet 43 therefore has several feed lines, two feed lines 61 and 62 in FIG Fig. 7 are shown.
  • Fig. 8 can be seen in a schematic representation by means of the arrows 63 that the container serving as the heat exchanger 24 is exposed to washing liquor.
  • the container has multiple ports with two of the ports in Fig. 8 can be seen, namely the connections 64 and 65.
  • the rinsing liquor circulated in the first flow circuit 25 reaches the heat exchanger 24 via the connections 64 and 65. This is flowed through in accordance with the arrows 63, the rinsing liquor again the heat exchanger 24 via the outlet 60 leaves.
  • the container bottom 59 of the heat exchanger 24 is designed to be inclined, the angle of inclination ⁇ being in particular at least five degrees.
  • Fig. 9 shows the fresh water tank 23 in a perspective illustration.
  • a cover 67 is provided as a first half part 49 and a base body 66 is provided as a second half part 50. In the final assembled state, these are welded to one another in the manner already described.
  • Fig. 10 shows a schematic exploded view. It shows the base body 66, the heat exchanger 24 accommodated by it in the final assembled state and the cover 67 closing the base body 66.
  • the heat exchanger 24 is shown in a schematic perspective illustration in FIG Fig. 11 shown. As can be seen from this illustration, the heat exchanger 24 has a total of three connections, namely the connections 64 and 65 already mentioned and the additional connection 68. The illustration according to FIG Fig. 11 also shows the channels 51 well.
  • Fig. 12 shows in a schematic plan view from above a heat exchanger 24 through which wash liquor flows.
  • wash liquor flows into heat exchanger 24 via connections 64, 65 and 68 and is distributed here in accordance with arrows 63
  • Fresh water circulated in the second flow circuit 26 flows separately from the rinsing liquor through the channels 51 and the throughflow openings 45 connecting the two compartments with one another in terms of flow. This achieves a heat transfer from the rinsing liquor to the fresh water.
  • the Figures 13 and 14th allow the fresh water tank 23 to be seen in two different side views.
  • the Figures 15 and 16 finally show a special embodiment of the channels 51. Thereafter, it is provided that the walls of the channels 51 are designed to be wavy or corrugated, at least in sections, as is shown by way of example in the area of section 69. This wave-like or corrugated design creates an enlarged effective surface for heat transfer between the washing solution and fresh water.
  • the configuration according to the invention makes it possible overall to transfer an increased amount of thermal energy from a first wash cycle to several subsequent wash cycles.
  • the existing Optimized use of installation space in that, on the one hand, a side tank is provided as the first fresh water tank 17 and a base tank is provided as the second fresh water tank 23. This maximizes the total usable volume of fresh water.
  • the heat exchanger 24 designed as a container in the manner described above, has both the character of a heat storage tank and that of a flow-optimized channel geometry due to its special design. This results in considerable energetic advantages.
  • the internal volume is approximately four times larger and the entire heat exchanger surface is more than twice larger.
  • the heat exchanger 24 is very compact overall. Therefore, the heat exchanger 24 can transfer significantly more heat energy to the fresh water of the wash cycles following a cleaning program than is the case with previously known heat recovery systems for dishwashers.
