Definitions

  • the invention relates to a dishwasher, in particular a household dishwasher, with a washing compartment that provides a washing chamber and is used to hold items to be washed to be cleaned, and with a fresh water tank that is arranged next to the washing compartment as a side tank, which is designed in one piece and consists of plastic.
  • Dishwashers in general and those with a fresh water tank in particular are well known per se from the prior art, which is why separate printed evidence is not required at this point. It is therefore only an example of the DE 42 33 643 C2 and the DE 10 2007 041 305 A1 referred.
  • the example from the DE 10 2007 041 305 A1 known dishwasher has a washing container that provides a washing area. This is accessible to the user via a loading opening which can be closed in a fluid-tight manner by means of a pivotably mounted washing compartment door. When used as intended, the washing container is used to hold items to be cleaned, which can be crockery, cutlery and/or the like, for example.
  • the dishwasher In order to apply washing liquid, the so-called washing liquor, to items to be washed to be cleaned, the dishwasher has a spray device inside the washing container.
  • This spray device typically provides rotatably mounted spray arms, with two or three such spray arms being provided as a rule.
  • the items to be cleaned are subjected to washing liquor by means of rotating spray arms.
  • the washing liquor has to be heated to a predeterminable target temperature, for example during the actual cleaning phase or the rinsing phase.
  • a predeterminable target temperature for example during the actual cleaning phase or the rinsing phase.
  • heat losses largely result from the fact that at the end of a washing phase, the heated and still warm washing liquor is pumped out and discarded.
  • Cold fresh water is then used for a subsequent wash cycle, as a result of which the temperature of the entire wash system drops significantly. In further subsequent washing phases, it is then necessary to heat the washing liquor again.
  • the DE 42 33 643 C2 proposes in this context a reservoir for fresh water, which is arranged next to the rinsing tank as a side tank. The reservoir rests on the rinsing container in a thermally conductive manner, so that from the time it is filled with fresh water, thermal energy is withdrawn from the rinsing container and transferred to the fresh water stored in the reservoir.
  • the DE 42 33 643 C2 structurally proposed to form the reservoir in two parts and to form the side wall of the reservoir facing the washing compartment from a thin, three-layer film.
  • the design of the side wall facing the washing compartment as a film is in accordance with the DE 10 2007 041 305 A1
  • it is perceived as disadvantageous because the film is complicated to assemble or to connect to the other components of the reservoir and, moreover, there is a not inconsiderable risk of damaging this film during assembly.
  • the DE 10 2007 041 305 A1 it is therefore proposed to produce the reservoir in one piece from two half-shells made of plastic welded together, the half-shells being made of an inflexible material and having the same wall thickness throughout in the range of 0.5 mm to 2 mm, in particular for reasons of improved stability.
  • the invention proposes a dishwasher of the type mentioned at the outset, which is characterized in that a side wall of the fresh water tank facing the washing compartment has a wall section which rests without a connection on the washing compartment and is designed to be deformable under water pressure.
  • the fresh water tank according to the invention is designed in one piece and consists of plastic.
  • “in one piece” within the meaning of the invention also means individual components that are connected to one another in a quasi one-piece manner by material bonding, for example by means of welding and/or gluing.
  • half-shells produced by injection molding can be provided as individual components, which are connected to one another to form the fresh water tank, in particular by welding and/or gluing, in such a way that non-destructive separation is not possible.
  • the fresh water tank designed in this way has a side wall which faces the washing tank and which, according to the invention, provides a wall section which on rinsing tank is connected without a connection. There is therefore no direct connection between the fresh water tank and the washing tank in the area of this wall section. Provision is also made for this wall section, which rests without a connection on the washing container, to be designed to be deformable under water pressure.
  • This configuration according to the invention provides the following advantages. On the one hand, it is simple to manufacture and assemble, which means that the configuration according to the invention is inexpensive. Because the preferably two half-shells forming the fresh water tank can be produced in the usual way, for example by injection molding, connected to one another and then arranged on the washing tank. On the other hand, improved heat transfer between the fresh water tank and the rinsing tank is made possible. As long as the fresh water tank is empty, a heat-insulating air gap forms between the washing tank and the fresh water tank, which is made possible by the fact that the wall section of the side wall of the fresh water tank facing the washing tank rests against the washing tank without any connection.
  • the wall section lies against the washing tank in a form-fitting manner and without a gap, so that an optimized heat transfer between the fresh water tank and the washing tank is made possible.
  • a gap-free abutment of the wall section when the fresh water tank is full is structurally permitted because the wall section is designed to be deformable under water pressure.
  • the configuration according to the invention thus synergistically enables improved heat transfer to the fresh water tank on the one hand, which reduces the total energy consumption of the dishwasher when used as intended, and this while minimizing costs in terms of production and assembly on the other.
  • the fresh water tank can be manufactured and assembled in the usual way and has sufficient inherent stability to avoid unwanted transport and assembly damage.
  • the side wall of the wall section has a reduced wall thickness compared to a side wall of an adjacent wall section.
  • the wall section that can be deformed under water pressure is designed in that it has a reduced wall thickness, specifically in comparison to adjacent wall sections. Reducing the wall thickness makes it possible for the wall section designed in this way to be able to exploit its side wall, so that when the fresh water tank is filled with water it rests against the associated side wall of the washing tank. There is thus a positive fit between the fresh water tank and the rinsing tank in the manner already described above, which, when used as intended, enables an optimized heat transfer from the rinsing tank to the fresh water stored in the fresh water tank.
  • the side wall of the wall section has a thickness of less than 1 mm, preferably between 0.5 mm and 1 mm.
  • the reduced wall thickness is therefore preferably less than 1 mm.
  • the side wall of an adjacent wall section has a thickness of greater than 1 mm, preferably between 1 mm and 2 mm, even more preferably 1.8 mm.
  • the non-reduced wall thickness is therefore preferably more than 1 mm.
  • the reduced wall thickness corresponds to half the non-reduced wall thickness. This can be designed particularly easily in terms of manufacturing technology and enables sufficient deformability of the wall section equipped with a reduced wall thickness, so that this wall section can be placed against the washing container in the manner already described above when it is used as intended.
  • the wall section of a surrounding fold This folding allows the wall section to bulge in the manner of a bellows.
  • the wall thickness is the same for all wall sections.
  • both the side wall of the wall section has a reduced wall thickness compared to a side wall of an adjacent wall section and the wall section is surrounded by a circumferential fold.
  • the fold is a bead. This enables a particularly simple and inexpensive manufacture.
  • a structurally robust configuration is provided, which is durable and allows the wall section to be placed securely against the washing container when used as intended.
  • the bead has a depth of between 4 mm and 20 mm, preferably between 6 mm and 14 mm.
  • a fold according to the invention in the form of a bead is a section according to which the side wall is guided in two layers in the manner of a loop. This double layering allows the wall section enclosed by the fold to move in relation to adjacent wall sections when used as intended.
  • the depth of the bead corresponds to the overlapping area, so that the possible movement of the wall section corresponds to half the depth of the bead.
  • a depth of the bead of 4 mm therefore allows the wall area enclosed by the bead to move by 2 mm in relation to adjacent wall sections.
  • the depth of the bead is between 6 mm and 14 mm, with the possibility of movement of the wall section being between 3 mm and 7 mm.
  • the side wall of the fresh water tank facing the washing tank has a bearing rib in a wall section adjacent to the wall section. When the fresh water tank is full, this contact rib is in contact with the washing tank, which leads to a defined spacing of the fresh water tank in the area of this wall section from the washing tank.
  • the contact rib thus advantageously ensures that on the one hand the wall section that is deformable under water pressure rests without a gap and in a form-fitting manner on the washing container, but that on the other hand the wall sections adjacent thereto are objected to with the interposition of the contact rib to the washing container.
  • a defined gap space is created, which thermally insulates the wall sections provided with a contact rib from the washing compartment. An undesired introduction of heat into these wall sections of the fresh water tank is therefore reliably prevented.
  • the contact rib surrounds the wall section all the way around. Accordingly, it is provided that the wall section deformable under water pressure is supported circumferentially by means of the contact rib relative to the washing compartment, so that only this wall section bears positively against the washing compartment when used as intended. Otherwise, the side wall of the fresh water tank is spaced apart from the washing tank, forming an air gap.
  • the side wall of the fresh water tank facing the washing compartment provides a recess open to the washing compartment for receiving a functional element in a wall section adjacent to the wall section.
  • the recess serves to be able to arrange additional elements, in particular functional elements, between the fresh water tank and the washing tank.
  • it is designed to be open to the washing container, so that the recess can be equipped in a simple manner if required.
  • a functional element is a pipeline, for example.
  • This pipeline can, for example, be fluidically connected to the rinsing tank, whereby in the final assembled state it extends from the recess of the Fresh water tank was added and is thus arranged to save space between the fresh water tank and the rinsing tank.
  • the recess can at least partially surround the wall section, which is designed to be deformable under water pressure. Consequently, the recess is not passed through the wall section, but placed around it.
  • the side wall of the fresh water tank facing away from the washing tank has a transverse rib running in the width direction.
  • This transverse rib serves to stabilize the fresh water tank.
  • the transverse rib is thermally advantageous because it blocks the circulation of an air flow on the outside of the fresh water tank.
  • the transverse rib rests on the inside of a housing of the dishwasher, with which any air circulation between the outside of the fresh water tank and the inside of the housing is reliably prevented.
  • a plurality of transverse ribs arranged one above the other in the height direction is provided.
  • the avoidance of undesired air circulation is improved even further.
  • the side wall of the fresh water tank facing away from the washing tank is designed to be thermally insulated. This minimizes the unwanted loss of thermal energy as a result of a heat transfer via the side wall of the fresh water tank facing away from the washing tank.
  • the thermal insulation can be achieved in a simple manner using a suitable insulating material that is attached to the outside of the side wall of the fresh water tank and/or the associated inner wall of a housing of the dishwasher.
  • provision can be made for the side wall of the fresh water tank facing away from the washing tank to be double-walled. Between the two walls of the double-walled side wall can be filled with air as hollow chambers
  • figure 1 and 2a to 2c each show a schematic representation of the basic structure of a dishwasher 1, as is also known from the prior art.
  • the dishwasher 1 has a housing 18 ( Figure 2c ), which accommodates, among other things, a rinsing container 2.
  • the washing compartment 2 in turn provides a washing chamber 3 which, when the dishwasher 1 is used as intended, is used to hold items to be washed.
  • a spray device 4 which is arranged inside the washing container 2 , is used to charge the items to be washed with washing liquor.
  • the rinsing chamber 3 opens into a collection pot 6 of the rinsing compartment 2, not shown in detail, to which a circulating pump 7 is fluidically connected.
  • the spray device 4 is fluidically connected to the circulating pump 7 via the pipelines 8 .
  • the spray device 4 in the exemplary embodiment shown has three spray arms 5 which, when used as intended, are supplied with washing liquor by means of the circulating pump 7 .
  • the dishwasher 1 also has a fresh water container 9 which is arranged on the outside of the washing container 2 on the washing container 2 .
  • the dishwasher 1 is fluidically connected to a fresh water connection 10 by means of a pipeline 13 .
  • a valve 11 is integrated into the pipeline 13, to which the pipeline 12, which opens into the fresh water tank 9, is also connected on the outlet side. Depending on the position of the valve 11 , fresh water delivered via the fresh water connection 10 can reach the collection pot 7 either via the pipeline 13 or the fresh water tank 9 via the pipeline 12 .
  • the fresh water tank 9 On the outlet side, the fresh water tank 9 is fluidically connected to the pipeline 13 by means of a pipeline 15 .
  • a check valve 14 is integrated into the pipeline 15 so that fresh water originating from the fresh water tank 9 can only reach the collection pot 6 via the pipeline 15 and the pipeline 13 when the valve 14 is open.
  • the circulation pump 7 has an integrated heater. If necessary, the washing liquor circulated by the circulating pump 7 can be heated to a target temperature depending on the program. figure 1 can be seen from the arrows 16 that there is a flow of heat in the direction of the fresh water stored by the fresh water tank 9 when the washing liquor has a temperature due to heating that exceeds that of the fresh water tank 9 stored water.
  • the Figures 2a to 2c show, for example, the washing tank 2 and the fresh water tank 9 arranged on the side thereof.
  • a section of the housing 18 can also be seen, which protects the fresh water tank 9, among other things.
  • a gap 19 can also be seen between the fresh water tank 9 and the rinsing tank 2, which cannot be avoided due to manufacturing tolerances. In this case, this gap 19 is undefined due to component and assembly tolerances and can therefore also turn out to be significantly larger than theoretically designed. This gap 19 ensures a reduced flow of heat between the washing compartment 2 and the fresh water tank 9.
  • an undefined gap 20 also occurs between the housing 18 and the fresh water tank 9 .
  • the outward flow of heat into the atmosphere surrounding the dishwasher 1 is increased when the fresh water container 9 is at least partially in contact with the washing container 2 .
  • this undesired flow of heat is also increased if the gap 20 turns out to be too large, since this increases the heat dissipation by convection or air movement in the gap 20 .
  • the invention proposes that the fresh water tank 9 has a side wall 21 facing the washing tank 2 with a wall section 22 which rests without a connection on the washing tank 2 and is designed to be deformable under water pressure.
  • This inventive design is in different embodiments in the Figures 3a to 8c shown.
  • the wall portion 22 is defined in that the side wall 21 in this area has reduced wall thickness 24 compared to adjacent wall sections 23 .
  • the wall thickness 24 in the area of the wall section 22 is 0.5 mm
  • the wall thickness 25 in the area of the adjacent wall section 22 is 1.5 mm or more.
  • a fold in the form of a bead 26 surrounding the wall section 22 is also provided.
  • This bead 26 allows the wall section 22 to move relative to the adjacent wall section 23 in the manner of a bellows. So when the fresh water tank 9 is filled with fresh water 28 , the wall section 22 is pressed outwards by the water pressure and thus against the washing tank 2 .
  • the depth of the bead 26 determines the possible movement distance of the wall section 22, in a ratio of 2:1.
  • the feature of the bead 26 is combined with the feature of the reduced wall thickness 24 .
  • each of these two individual measures is already sufficient in itself to enable the wall section 22 to be placed against the washing container 2 when the fresh water container 9 is full.
  • a contact rib 27 is provided, which preferably encloses the peripheral bead 26 peripherally.
  • This contact rib 27 is in particular also when the fresh water tank 9 is filled on the outside of the washing tank 2, as is the case Figures 3c and 4c reveal.
  • This contact rib 27 ensures that the wall section 23 adjacent to the wall section 22 is arranged at a distance from the washing compartment 2 while leaving a gap 29 .
  • This gap 29 ensures that there is no undesired input of heat from the washing compartment 2 into the wall section 23 .
  • the fresh water tank 9 has a depression or bead 26 on the outside of its side wall 21 facing the washing tank 2 , which delimits a thin-walled wall section 22 which heat can be optimally transferred when used as intended.
  • the side wall 21 of the fresh water container 9 is designed to be comparatively thick (for example >1.8 mm), as a result of which the fresh water container 9 is sufficiently stable. Because of the bead 26, the thin-walled wall section 22 can deform more easily and rests against the wall of the washing compartment as soon as the fresh water tank 9 is filled with water 28.
  • the bead 26 and the smaller wall thickness 24 within the wall section 22 enclosed by the bead 26 ensure that there is direct contact over the entire heat transfer surface between the wall section 22 and the wash tub wall. Due to the water pressure, this area 22 is deformed in a defined manner to form the washing container 2.
  • the fresh water tank 9 is designed in such a way that the thin-walled wall section 22 is at a clear distance of several millimeters from the rinsing tank 2 when it is not filled and is therefore without tension.
  • the thin contact rib 27 is formed directly onto the bead 26 and ensures a defined distance from the washing compartment 2 and, because of its wall thickness, always bears against the washing compartment 2 . This ensures that there is always a closed space or gap in the thin-walled transfer area 22 when the fresh water tank 9 is not filled, which prevents free convection of the air due to being enclosed by the contact rib 27 and thus has a heat-insulating effect.
  • This gap space is delimited by the washing compartment 2, the thin-walled side wall 21 in the area of the wall section 22 and by the circumferential contact rib 27.
  • the contact rib 27 ensures that there is a defined distance from the washing compartment 2 in the areas that are not or should heat up less by heat transfer.
  • the Figures 4a to 4c show the fresh water tank 9 in the filled state, in which the thin-walled wall section 22 rests against the washing tank 2 due to the prevailing water pressure. Since the deformation takes place in a defined manner, in particular by the bead 26, the entire wall section 22 rests against the washing container 2, as a result of which the gap between the fresh water container 9 and the washing container 2 is completely closed. As a result, in the filled state of the fresh water tank 9, the heat flow between the washing tank 2 and Fresh water tank 9 improved.
  • the assembly drawing figure 5 shows the thin-walled wall section 22 and the bead 26 that surrounds this section all the way round, as well as the contact rib 27 that is also formed all the way round.
  • Attachment points 36 are provided for arranging the fresh water tank 9 . These are provided outside of the thin-walled wall section 22 so that a water pressure-induced deformation of the wall section 22 is not impeded by the fastening points 36 .
  • the fresh water tank 9 is therefore in the area of the wall section 22 without any connection to the washing tank 2 .
  • FIG 6 reveals a further embodiment, according to which the side wall 21 of the fresh water container 9 facing the washing compartment 2 carries a recess 30 which is open towards the washing compartment 2 .
  • a pipeline 31 is embedded as a functional element in this recess 30 . In the final assembled state, this pipeline 31 is fluidically connected to the rinsing tank 2 , being located between the fresh water tank 9 and the rinsing tank 2 .
  • FIG 6 also shows an opening 37 protruding through the wall section 22 .
  • This opening 37 is used, for example, to pass through a connecting piece 38 which is fluidically connected to the washing compartment 2.
  • a bead surrounding the opening 37 is provided , which is formed in correspondence with the bead 26.
  • the Figures 7a to 7c reveal a further embodiment according to which the fresh water tank 9 has a transverse rib 33 running in the width direction on its outside.
  • a plurality of these transverse ribs 33 are provided, which are arranged one above the other in the vertical direction 34 .
  • These transverse ribs 33 function as spacers to the housing 18.
  • These transverse ribs 33 ensure a defined gap between the fresh water tank 9 and the housing 18 on the one hand.
  • the horizontal course of these transverse ribs 33 prevents free convection of the air. By preventing this free convection, the gaps between two in height direction serve 34 successive transverse ribs 33 as thermal insulation.
  • the gap width is preferably 2 mm.
  • the Figures 8a to 8c show another embodiment.
  • the side wall 32 of the fresh water tank 9 facing away from the washing tank 2 is double-walled and encloses cavities 35 .
  • These cavities 35 act as thermal insulation.
  • a first wall serving as an outer wall can be provided, for example, which is welded onto a second wall serving as an inner wall, forming the cavities 35.
  • the advantage of this solution, in addition to the thermal insulation, is the increased rigidity of the side wall 32. This increased rigidity has the particular advantage that the side wall 32 does not come into contact with the housing 18 when the fresh water tank 9 is filled, which reliably prevents an unwanted flow of heat is.
