Description

  The present invention relates to a dishwasher, in particular a household dishwasher, provided with at least one washing cabinet and at least one drying device for drying the washed items, Has at least one sorption container for containing a reversibly dewaterable sorption material, in particular a zeolite, and is dried to generate an air exchange between the washing cabinet and the sorption container. The present invention relates to a type in which at least one air guide passage for guiding air is provided between the apparatus and the cleaning cabinet.

  The so-called “sorption” for drying dishes, for example according to DE 10353774, DE 10353775 or DE 102005004096. A dishwasher with a "column" is known. In this known dishwasher, in the part program step “Drying” of each dishwashing program, moist air is guided from the dishwasher wash cabinet through the sorption column to dry the dishes. Moisture is then taken away from the air that is passed by condensation through the reversibly dewaterable dry material of the sorption column. For regeneration of the sorption column, i.e. desorption, the reversibly dewaterable dry material of the sorption column is heated to a very high temperature. As a result, the water occluded in this material flows out as high-temperature steam and is guided into the washing cabinet by the air flow generated by the blower. Accordingly, it is possible to heat the cleaning processing liquid and / or the tableware positioned in the cleaning cabinet and the air positioned in the cleaning cabinet. This type of sorption column has been found to be extremely advantageous for energy-saving and quiet drying of dishes. In order to avoid local overheating of the dry material during the desorption process, for example, in DE 10 2005 04096 the heating means is in front of the air inlet of the sorption column as viewed in the direction of air flow. Has been placed. Despite this “air heating” at the time of desorption, in practice it remains difficult to always dry the reversibly dewaterable drying material sufficiently and satisfactorily.

  The object of the present invention is to provide a dishwasher, in particular domestic tableware, which can achieve a further improved sorption result and / or desorption result for the reversibly dewaterable drying material of the sorption unit of the sorption drying apparatus. Is to provide a washing machine.

  In order to solve this problem, in the dishwasher according to the present invention, the sorption container is housed in the bottom assembly provided below the bottom of the washing cabinet.

  According to an advantageous aspect of the dishwasher according to the present invention, a reversibly dewaterable sorption material for absorbing the amount of moisture carried by air exchange in the sorption container has the following weight: That is, the amount of moisture absorbed by the sorbent material is set to a weight that is less than the amount of liquid applied to the wash, particularly the amount of liquid applied in one finishing rinse step.

  According to an advantageous aspect of the dishwasher according to the present invention, the sorption material that can be reversibly dehydrated in the sorption container has the following weight, that is, the sorption material that can be reversibly dehydrated. The amount of moisture absorbed by is provided at a weight that substantially corresponds to the amount of moisture that moistens the wash after the finish rinse step.

  According to an advantageous embodiment of the dishwasher according to the invention, the amount of moisture absorbed corresponds to 4% to 25%, in particular 5% to 15%, of the amount of liquid applied to the wash.

  According to an advantageous embodiment of the dishwasher according to the invention, the container can be reversibly dewatered in a weight of 0.2 kg to 5 kg, in particular 0.3 kg to 3 kg, preferably 0.5 kg to 2.5 kg. Sorptive material is present.

  According to an advantageous embodiment of the dishwasher according to the invention, the drying device is connected to at least one outlet and at least one inlet of the washing cabinet via at least one air guide passage.

  According to an advantageous aspect of the dishwasher according to the present invention, the air guide passage is arranged sufficiently outside the washing cabinet.

  According to an advantageous embodiment of the dishwasher according to the invention, the pipe section on the outflow side of the air guide passage is connected to at least one inlet provided in a region near the bottom of the washing cabinet.

  According to an advantageous aspect of the dishwasher according to the present invention, the pipe section on the inflow side of the air guide passage is at least one outlet provided above the bottom of the washing cabinet, particularly in the region near the ceiling of the washing cabinet. It is connected.

  According to an advantageous aspect of the dishwasher according to the invention, the pipe section on the inflow side of the air guide passage opens in the sorption container of the drying device in the region near the bottom, whereby the pipe on the inflow side The inflow direction of the section is changed to the direction of flow of the sorption container, in particular by about 90 °.

  According to an advantageous aspect of the dishwasher according to the invention, at least one blower for generating an air flow is provided in front of the drying device as seen in the direction of air flow.

  According to an advantageous embodiment of the dishwasher according to the invention, at least one heating element correspondingly arranged for desorption is provided between the blower and the drying device as viewed in the flow direction.

  According to an advantageous aspect of the dishwasher according to the present invention, the sorption material is placed in front of a sorption unit provided with a sorption material that can be reversibly dehydrated in the sorption container as viewed in the flow direction. At least one heating element for desorption is provided as a component of the sorption container.

  The present invention allows a sufficient amount of sorption material to be stored compactly in a dishwasher for a satisfactory sorption result and / or desorption result. Furthermore, the arrangement in the present invention of the sorption container in the bottom assembly provided below the bottom of the wash cabinet avoids losing construction space in the region of the side wall of the wash cabinet. That is, the inner and outer dimensions of the dishwasher can be kept substantially unchanged. This is advantageous, for example in a kitchen, for household dishwashers where a built-in niche with defined inner dimensions is set.

  According to an advantageous refinement of the invention, the reversibly dewaterable sorption material for absorbing the amount of moisture carried by the air exchange in the sorption container has a weight as follows: The amount of moisture absorbed by the dressing material is set to a weight that is less than the amount of liquid applied to the wash, particularly the amount of liquid applied in one finishing rinse step. Efficient with the use of a small amount of sorbent material, because the sorbent material in the sorption container is adapted to absorb less liquid part by weight than the total amount of liquid applied to the wash. Air moisture coupling is possible. This allows a compact structure for the sorption container.

  Thus, at the same time, it is ensured that the energy consumption for complete regeneration of the sorption material by heating with the heating means can be reduced. This is because, in the end, only the amount of sorbent material that is sufficient, adapted or metered in order to dry the wash well is heated.

  According to a first advantageous refinement of the invention, a reversibly desorbable sorbent material is advantageously provided in the sorption container, preferably in the following weight, i.e. reversibly dewaterable desorption. The amount of moisture absorbed by the dressing material is provided in a weight that substantially corresponds to the amount of moisture that moistens the wash after the finish rinse step. Here, the wetting amount means, in particular, after the finishing rinsing step, in which the already washed item is loaded with water mixed with a tension reducing agent, the item to be washed, a dish basket for containing the item and / or Or it is the amount of liquid that adheres to the inner wall of the washing cabinet and does not flow down to the bottom of the washing cabinet due to gravity. By this adaptation of the weight of the sorbent material, it is achieved that the moisture absorption capacity of this sorbent material is sufficient to couple or absorb the wet amount almost completely into the sorbent material by air exchange. The

  Advantageously, the sorbent material has a weight as follows, i.e. the amount of moisture absorbed corresponds to 4% to 25%, in particular 5% to 15% of the amount of liquid applied to the wash. It is stored in a sorption container with a heavy weight.

  Advantageously, there is a reversibly desorbable sorption material in the sorption container weighing between 0.2 kg and 5 kg, in particular between 0.3 kg and 3 kg, preferably between 0.5 kg and 2.5 kg.

  According to one advantageous aspect, the drying device may be connected to at least one outlet and at least one inlet of the wash basin via at least one air guide passage (VK). This enables air circulation in the closed circuit.

  In particular, it is advantageous if the air guide passages are arranged sufficiently outside the wash cabinet, so that the use space in the wash cabinet remains maintained, i.e. is not reduced.

  In particular, it may be proposed that the pipe section on the outflow side of the air guide passage is connected to at least one inlet provided in a region near the bottom of the wash cabinet. This is advantageous when the sorption container is housed in the bottom assembly of the dishwasher. In this way, the outflow path for the dried air from the sorption container to the inflow of the dishwasher wash can be kept short, thereby avoiding unwanted heat losses sufficiently.

  In particular, it may be proposed that the pipe section on the inflow side of the air guide channel is connected to at least one outlet provided above the bottom of the wash cabinet, in particular in the region near the ceiling of the wash cabinet. This sufficiently prevents water splashes from the spray device in the washing cabinet, for example during the main washing step, the final rinsing step or the intermediate rinsing step, from entering the inlet opening of the pipe section on the inflow side of the air guide passage. Is done. Otherwise, this leads to unwanted partial or total saturation of the sorbent material, in particular sorbent material damage or damage to the initial sorption and / or desorption properties, and this sorption material May be partially or completely unusable for a single drying of moist air from the wash cabinet.

  Further, in some cases, the pipe section on the inflow side of the air guide passage opens into the sorption container of the drying device in the region near the bottom, so that the inflow direction of the pipe section on the inflow side is in particular about 90 °. It can only be advantageous if the sorption vessel is only turned in the direction of the vertical flow. This allows, in part, the guidance of moist air from the wash cabinet through at least one inflow side pipe section located on the side wall and / or back wall of the wash cabinet in the air guide passage. It becomes. Secondly, the pipe section on the outflow side of the air guide passage can be extended almost linearly between the outlet opening of the sorption container and the inflow opening of the washing cabinet, and can be kept relatively short. it can. This is particularly advantageous when the pipe section on the outflow side of the air guide passage is connected to at least one inlet provided in a region near the bottom of the wash cabinet. Therefore, the pipe section on the outflow side of the air guide passage can be opened, for example, in an opening provided at the bottom of the cleaning cabinet. This sufficiently avoids heat loss especially when the sorption material is desorbed. This is because the air heated at the time of desorption that has advanced from the sorption container can flow into the washing chamber directly without any path loss. This improves the efficiency of the sorption drying device, especially during desorption.

  According to another advantageous refinement, at least one blower for generating an air flow may be provided in front of the drying device as viewed in the direction of the air flow. This allows a particularly effective forced flow through the sorption material.

  According to another advantageous refinement, at least one heating element correspondingly arranged for desorption may be provided between the blower and the drying device as viewed in the flow direction. This makes it possible to regenerate the sorption material, so that the sorption material is again fully regenerated and provided for the next dishwashing step to dry the wash.

  At least one heating element for desorbing the sorption material, in particular electrically, in front of a sorption unit with a reversibly desorbable sorption material, especially in the flow direction, as seen in the flow direction It may be advantageous if a heating element is provided as a component of the sorption container. This provides air heating. That is, the hot air can flow the sorption material sufficiently uniformly. Thus, so-called “hot spots”, ie local overheating points in the filling volume of the sorption material, are sufficiently avoided.

  According to an advantageous refinement, the drying device has at least one sorption unit with a reversibly dewaterable drying or sorption material, in particular a zeolite fixed bed or a zeolite packing. The zeolite packing is particularly preferably formed by small, spherical zeolite granulates. The dry material or sorption material is preferably housed in the container of the sorption unit or in the housing with approximately the same layer thickness. The container of the sorption unit is preferably partitioned or covered by at least one sieve at its air inlet opening and / or air outlet opening, respectively. This actually allows for sufficient air permeation at the same time as a compact packing of the sorption material, so that the sorption material can not only absorb moisture from the flow-through air sufficiently by condensation, In order to regenerate the sorbent material, the stored moisture can be released or desorbed again by heating through the flowing air.

  Other refinements of the invention are described in the dependent claims.

It is the schematic of the dishwasher provided with the washing | cleaning warehouse and the sorption drying system.

  The invention and its improvements are described in detail below with reference to only one drawing.

  FIG. 1 schematically shows a dishwasher GS. This dishwasher GS comprises a washing cabinet SB and a sorption drying system TS. This sorption drying system TS is advantageously provided outside, ie outside the washing cabinet SB of the dishwasher GS. The sorption drying system TS has, as main components, an air guide passage VK, at least one blower or fan GB, and a drying device TE. In the cleaning cabinet SB, for example, one or more lattice baskets GK for storing and cleaning dishes are stored. The drying device TE is connected to at least one outlet EL and at least one inlet AL of the cleaning cabinet SB via an air guide passage VK. The air guide passage VK is disposed sufficiently outside the cleaning cabinet SB. Specifically, the pipe section RA1 on the inflow side of the air guide passage VK is connected to an outlet EL provided in a region near the ceiling or an upper region located away from the bottom of the cleaning cabinet SB. The pipe section RA2 on the outflow side of the air guide passage VK leads to an inlet AL provided in a region near the bottom of the cleaning cabinet SB. In this way, air can be guided from the inside of the washing cabinet SB to the drying device TE via the air guide passage VK, for example during the drying step of the dish washing program, and is dried by the drying device TE into the washing cabinet SB. Can be returned, i.e. circulated through the sorption drying system TS. By an air inlet provided in the upper area of the washing cabinet SB, water is guided from a tank (omitted for the sake of clarity of the drawing) provided at the bottom of the washing cabinet SB or from the water spray system WS of the washing cabinet SB. The possibility of reaching the passage VK and the sorption container BEH of the drying device TE is sufficiently avoided. Otherwise, this can cause the sorption material to become unacceptably wet and unusable.

  In the present embodiment, the drying device TE is advantageously housed in a bottom assembly provided below the bottom of the cleaning cabinet SB or in a lower component unit BG. The drying device TE is formed as a so-called “sorption column”. This sorption column has at least one heating element HZ and a sorption unit SE placed downstream in the flow direction, in a common housing or in a container BEH. The sorption unit SE is equipped with a reversibly desorbable sorption material, such as zeolite ZEO. The sorption unit SE has a sorbent material fixed bed, in particular as a molecular sieve, preferably a zeolite fixed bed or a loose sorbent material packing, preferably a zeolite packing. Sorptive material packings, in particular zeolite packings, are preferably formed by small spherical loose granulates or other particles, preferably zeolite particles. The drying material or sorption material is advantageously arranged as a single layer or a multilayer with approximately the same layer thickness, spaced apart from each other in the height direction of the container or housing BEH of the drying device TE with a gap free chamber. A sorption unit SE is formed and stored in an intermediate chamber between the two sieves or the grid with holes. Both sieves are arranged at horizontal position levels in parallel with each other at a settable height interval. Each sieve is formed in a substantially flat surface or flat. Both sieves circulate around the outer peripheral surface in an annular shape and are surrounded or surrounded by the outer peripheral wall of the housing BEH as an outer partition member at the outer edge portion. Therefore, the sorption unit SE is arranged in one position level substantially horizontal in the housing BEH. In this way, the sorption unit SE is preferably partitioned or covered by its air inlet and / or air outlet openings, respectively, by at least one sieve or grid, whereby sorption material particles, in particular zeolites Particles are prevented from falling from the container BEH of the sorption unit SE, and at the same time air can flow from the air inlet opening through the interior of the sorbent material with a sufficiently low flow resistance to the air outlet opening. . The sorption unit SE advantageously has a substantially flat inlet-side inlet surface and a substantially flat outlet-side outlet surface. In practice, this type of sorption unit SE allows for a compact stuffing of the sorption material and at the same time sufficient air permeation, so that the sorption material is removed from the flowing air in the sorption process. Moisture can be fully absorbed by condensation, and in the desorption process, the stored moisture can be released or desorbed again by heating the stored moisture through the flowing air to regenerate the sorbent material.

  The housing BEH of the drying device TE is shaped so as to be able to flow by a substantially vertical air flow, and is positioned below the bottom of the cleaning cabinet SB. In other words, the housing BEH allows a passing direction from below to above through the incorporated sorption unit SE. For the air supply, the downstream end section of the pipe section RA1 on the inflow side of the air guide passage VK opens into the housing BEH in the region of its housing base or housing bottom. In the present embodiment, the downstream end section of the inflow side pipe section RA1 extends toward the base of the housing BEH at a substantially horizontal position level. The downstream end section is attached to the housing BEH substantially near the lower bottom. The downstream end section has a flow direction VS in which the air flow guided to this end section extends from the initially substantially horizontal flow direction LS through the housing BEH to a substantially vertical flow direction VS, here by about 90 °. It is connected to the housing BEH near the bottom so that it can be deflected. Generally speaking, the air flow LS arriving at the inflow side pipe section RA1 is changed from the original inflow direction to the flow direction VS in the region near the bottom of the housing BEH or the region of the chamber base. The flow direction VS through the housing BEH is substantially straight, in particular in the housing BEH, from the closed housing base to the outlet opening on the lid side or the outlet pipe piece provided on the lid of the housing BEH, here in the substantially vertical direction. It is the direction of the flow that flows through. An upstream end section of the outflow side pipe section RA2 of the air guide passage VK is connected to the outflow opening or the outflow pipe piece. In such a flow direction, a substantially horizontally packed layer of sorbent material in the sorption unit SE is flowed through or passed substantially vertically by the passing air flow.

  In order to desorb a reversibly desorbable sorption material, in particular zeolite ZEO, at least one heating element HZ is provided in the vicinity of the front of the inflow surface of the sorption unit SE in the housing BEH. Provides air heating for the sorption material. The heating element HZ is positioned at a position level in front of the inflow surface. This position level extends from the inflow surface substantially parallel to the inflow surface with a configurable gap spacing to avoid local overheating of the sorbent material inlet surface. The heating element HZ is preferably formed by a heating rod or a heating spiral. In particular, each heating element HZ extends over substantially the entire internal width of the inflow cross section of the sorption unit SE with a reversibly dewaterable drying material. This makes it possible to heat the air flow in the area of the longitudinal wall of the sorption unit SE extending in the depth direction, i.e. also in the middle area of the cross-sectional width of the sorption unit SE, in particular at the side edges. It becomes. In this way, local wet spots in the dry material are avoided sufficiently, especially in the region of the side wall of the sorption unit SE during desorption. That is, uniform drying of the sorption material can be ensured. If the width of the sorption unit SE corresponds approximately to the inner width of the housing BEH of the drying device TE, the heating element HZ is in front of the inflow cross section of the sorption unit SE, preferably almost the entire housing BEH. It extends over the inner width. The inflow cross section of the sorption unit SE can be heated as much as possible for the desorption of the sorption material volume of the sorption unit SE and thus sufficiently homogeneously, so that the sorption material volume In order to sufficiently avoid local heating deficiencies in the case, the heating element HZ is preferably laid in a meandering line or meander shape when viewed in the depth direction of the sorption unit SE, in particular the housing BEH. . The meander meander of the heating element HZ preferably extends back and forth in the depth direction over the entire inner width of the inflow surface of the sorption unit SE between the side walls of the housing BEH. In particular, the meandering of the heating element HZ is located at substantially the same position level.

  In order to generate a forced air flow through the air guide passage VK, a blower GB is provided in the inflow side pipe section RA1 in front of the sorption unit SE of the sorption vessel BEH as viewed in the flow direction.

  That is, when considered together, the air guide passage VK starts from the washing cabinet SB and communicates with the drying device TE, and is returned to the washing cabinet SB from there. A blower GB is arranged in the air guide passage VK in front of the drying device TE. By this blower GB, air is sucked from the cleaning cabinet SB and blown back into the cleaning cabinet SB through the drying device TE. In the sorption container BEH of the drying device TE, one of the reversibly dewaterable sorption material located inside absorbs moisture, thereby drying the sucked air. The sorbent material is again dried by at least one heating element HZ at a defined time interval, i.e. dehydrated, and thereby ready to absorb moisture absorption from the air again. .

  In the sorption vessel BEH, a reversibly desorbable sorption material, in particular zeolite ZEO, for absorbing the amount of moisture carried by air exchange, is advantageously weighted as follows: sorption material Is provided in such a weight that is less than the amount of liquid applied to the wash, in particular less than the amount of liquid applied in one finishing rinse step. The sorbent material in the sorption vessel BEH is adapted to absorb less liquid part with respect to its weight than the total amount of liquid applied to the wash, thereby reducing the efficiency of the use of a small amount of sorbent material. Good air moisture binding is possible. This allows a compact structure for the sorption container BEH.

  Thus, at the same time, it is ensured that the energy consumption for complete regeneration of the sorption material by heating with the heating means can be reduced. This is because, in the end, only the amount of sorbent material that is sufficient, adapted or metered in order to dry the wash well is heated.

  In particular, the reversibly dewaterable sorbent material is advantageously weighted as follows, i.e. the amount of moisture absorbed by the reversibly dewaterable sorbent material after finishing the rinsing step It may be provided in the sorption container BEH with a weight substantially corresponding to the wet amount to be wetted. Here, the wetting amount refers in particular to the washed product, the tableware basket GK for containing the washed product, and the finished washing step after the finish rinse step of loading the washed product with water mixed with a tension reducing agent. It is the amount of liquid that adheres to the inner wall of the washing cabinet SB and does not flow down to the bottom of the washing cabinet due to gravity. By this adaptation of the weight of the sorbent material, it is achieved that the moisture absorption capacity of this sorbent material is sufficient to couple or absorb the wet amount almost completely into the sorbent material by air exchange. The

  Advantageously, the sorbent material has the following weight, i.e. the amount of moisture absorbed corresponds to 4% to 25%, in particular 5% to 15% of the amount of liquid applied to the wash. It is stored in the sorption container BEH with a heavy weight.

  Advantageously, there is a reversibly dewaterable sorption material in the sorption vessel BEH weighing between 0.2 kg and 5 kg, in particular between 0.3 kg and 3 kg, preferably between 0.5 kg and 2.5 kg. .
