Definitions

  • the invention relates to a dishwasher, in particular in the embodiment of a domestic dishwasher, with a washing compartment providing a washing compartment, which serves to receive items to be cleaned, a collecting pot, in which the washing fluidly opens and a circulation pump, the fluidically to the collecting pot by means of a suction line connected.
  • Dishwashers of the type described above are well known from the prior art, which is why a separate documentary proof at this point is not required. It is therefore only an example of the DE 10 2005 008 987 B3 directed.
  • Dishwashers of the generic type have a washing container, which provides a washing compartment.
  • This washing compartment is accessible on the user side via a charging opening which can be closed in a fluid-tight manner by means of a pivotally mounted flushing door.
  • the washing container serves to receive items to be cleaned, which in the case of a domestic dishwasher may be, in particular, dishes, cutlery pieces and / or the like.
  • the dishwasher For loading of items to be cleaned with rinsing liquid, also called rinsing liquor, the dishwasher has a scavenging chamber side formed spray.
  • This spraying device generally provides rotatably mounted spray arms, with typically two or three such spray arms being provided. In the intended use case, a loading of the items to be cleaned with rinse liquor by means of rotating spray arms.
  • a circulating pump is provided, which is fluidly connected on the one hand to the collecting pot and on the other hand to the spray arms.
  • the sprayer When used as intended, that of the sprayer collects discharged rinsing liquor in the collecting pot, in which the washing fluid flows out.
  • the circulating pump conveys the rinsing liquor accumulating in the collecting pot to the spray arms of the spraying device, from where then a discharge of the washing liquor to the items to be cleaned takes place.
  • the collecting pot into which the rinsing container discharges, is separated from the rinsing container provided by the rinsing container by a screening device.
  • the rinsing liquor circulated in the intended use case by the circulating pump therefore accumulates in the collecting pot only after passing through the screening device inserted into the collecting pot. Leftovers, dirt particles and / or similar impurities are retained by the sieve device, so that it comes to circulation of a so far purified by screening rinsing liquor.
  • a screening device of the previously known type typically has a coarse screen, a fine screen and a flat screen.
  • the surface sieve comes to lie in the final assembled state in a recess corresponding to the surface sieve in the bottom of the washing container.
  • the fine screen of the screening device is typically cylindrical.
  • the fine sieve In normal operation, the fine sieve is flowed through from the inside to the outside, so that accumulated on the fine sieve impurities accumulate inside the cylinder-shaped fine sieve and form there a so-called filter cake.
  • the permeability of the fine sieve for rinsing liquor is reduced, which hampers the intended course of a rinsing program.
  • the fine screen is therefore from time to time to clean manually by the user, which is expensive and the extent that the user perceived as disadvantageous. If such a cleaning on the part of the user does not occur, insufficient washing results may result.
  • a dishwasher of initially mentioned type which is characterized in that the circulation pump is an axial pump and that a second suction line is provided, by means of which the circulation pump is fluidly connected to the collecting pot.
  • the circulating pumps typically used in the prior art are radial pumps, as in the embodiment according to the aforementioned DE 10 2005 008 987 B3 , In contrast to this, it is proposed with the invention that an axial pump is used as a circulation pump.
  • the big advantage of an axial pump compared to a radial pump is that it is possible by reversing the impeller rotation to change the pump delivery direction.
  • An axial pump can therefore be switched from left to right rotation and vice versa, which leads to a change in delivery direction.
  • By means of an axial pump it is therefore possible to selectively divert rinsing liquid from the collecting pot by means of a change of the impeller turning direction or to introduce it into the collecting pot.
  • a second suction line is further provided.
  • this second suction line formed as an axial circulation pump is fluidly connected to the collecting pot.
  • a first suction line and a second suction line are therefore provided, wherein both suction lines form a fluidic connection of the circulating pump to the collecting pot.
  • a backwashing is also known from the prior art according to DE 10 2005 008 987 B3 possible.
  • the construction described here is very complicated and comparatively complicated in the control technology handling. Because the construction after the DE 10 2005 008 987 B3 requires the use of a separate backwash pump. Accordingly, not only a sewage pump and a circulating pump are provided, but also a backwashing pump. Accordingly, it also requires complex lines to realize the fluidic connection of all pumps.
  • the embodiment of the invention is compared to the construction of the DE 10 2005 008 987 B3 built much easier, and in particular, because a separate backwash pump is not required.
  • both the rinsing operation and the backwashing operation are carried out via one and the same circulating pump.
  • the construction according to the invention is therefore much more compact in contrast to the prior art.
  • the conduction paths in the embodiment according to the invention are much shorter than in the prior art, which has a favorable effect on water consumption. Because for a proper flushing operation, it requires a minimum level within the collecting pot, so that a more cable path inevitably leads to increased water consumption.
  • the fine filter of the screening device can be backwashed in a simple manner with the help of the already existing circulation pump. This simplifies the handling of the dishwasher by the user and in particular allows a minimization of a fine screen cleaning to be carried out manually by the user.
  • the second suction line has a suction section projecting into the collecting pot.
  • the suction line does not open into the collecting pot on the circumference, but instead a suction section in the form of a nozzle is provided, which protrudes into the collecting pot.
  • a suction section in the form of a nozzle is provided, which protrudes into the collecting pot.
  • the suction section provides a suction opening that lies above the bottom of the collecting pot. The spacing provides the advantage that in the case of a backwash from the filter solubilizing particles can accumulate at the bottom of the collecting pot and not sucked through the second suction and circulated in the backwash.
  • the suction section provides a suction opening, which is above the junction of a sewer connected to the sewer pipe. It is thus advantageously allowed to replace adhering particles by backwashing the filter, which then accumulate in the lower part of the collecting pot, from where then after completion of a backwash pumping can take place through the sewer pipe. The particles accumulating in the collection pot through a backwash can thus be discharged via the sewer pipe.
  • the circulation pump is connected directly to the second suction line.
  • both the first and second intake pipes are directly connected to the circulation pump.
  • the circulation pump has accordingly to have two connections for suction lines.
  • the circulation pump is connected to a supply line leading to a spray arm arranged in the washing container, wherein the second suction line opens into the supply line. Accordingly, the second suction line is not connected directly to the circulation pump, but indirectly with the interposition of a portion of a supply line connected to the circulation pump.
  • a circulation pump is typically connected to a suction line and to a Supply line connected.
  • rinsing fluid passes via the suction line to the circulating pump, from where the supply line is then acted upon.
  • the supply line is in turn connected to at least one spray arm of the spray device of the dishwasher. In normal operation, therefore, the Spülflottenhne from the collecting pot via the intake takes place in the circulation pump and from there via the supply line to the spray arm.
  • the inventively provided second intake pipe is now connected to the supply line.
  • suction of washing liquor from the collecting pot takes place via the second suction line, wherein the washing liquor conveyed via the second suction line flows into the supply line connected to the suction line and from there to the circulating pump.
  • a recirculation circuit results via the second intake line, the supply line, the circulation pump and the first intake line, wherein the first intake line does not act as intake, but as discharge line in the backflushing operation.
  • a blocking means in particular a check valve, cooperating with the second suction line is provided.
  • this blocking means or check valve and thus also the second suction line is blocked.
  • the rinsing liquor promoted in pump operation is thus conveyed solely via the supply line to the spray arm connected thereto.
  • the blocking means of the second suction line is opened, so that washing liquor can be conveyed from the collecting pot via the second suction line and the adjoining supply line in the reverse conveying direction.
  • a water diverter may be provided as a blocking means, in particular the already existing water diverter, which, moreover, serves to guide the rinsing liquor, starting from the circulating pump, alternately to the different spray arms.
  • This water switch can be connected downstream of the circulation pump and / or integrated into the circulation pump or the circulation pump housing.
  • connection of the second intake line to the supply line is preferred because the already existing line paths, in particular the already existing supply line, can be used. Both the construction costs and the length of the cable routes are minimized.
  • the second suction line is formed by a line section of a collecting duct projecting through the collecting pot and connected to a spray arm.
  • the spraying device of a dishwasher typically has three spray arms. There are provided an upper, a middle and a lower spray arm.
  • the upper and middle spray arm are operated via separate or via a common supply line with rinsing liquor.
  • the lower spray arm is connected to a separate supply line, which makes it possible to operate the lower spray arm independently of the other two spray arms.
  • the supply line provided for the lower spray arm is guided, starting from the circulation pump or a water distributor connected thereto, through the collecting pot. This structural design is particularly useful when both the collecting pot and the lower spray arm are aligned centrically in relation to the Spül organizationser founded.
  • a portion of this leading to the lower spray arm supply line can be used according to the invention as a second suction line.
  • this line is used in the flushing operation as a supply line for the lower spray arm and backwash as suction for the circulation pump.
  • the supply line has a suction opening which automatically opens and / or closes depending on the spooling pressure; in particular, it is in a first direction through the supply line when the rinsing liquor is conveyed. in rinsing, closed and in the promotion of the washing liquor in the opposite direction, i. in backwash mode, opened.
  • the supply line is for this purpose preferably formed in two parts, wherein the two line parts are arranged telescopically to each other. In the overlap region of the pipe parts openings are formed in the pipe walls. These come in the contracted state of the two line parts in coverage. In the extended state of the two line parts such coverage is not given.
  • This configuration has the effect that, in the rinsing operation, the rinsing pool pressure generated by the circulating pump ensures that the two line parts are moved apart, so that the supply line is tight due to lack of coverage of the wall openings, thus promoting the rinsing liquor to the spray arm connected to the supply line in the intended manner can take place.
  • the invention further proposes a method for operating a dishwasher of the type described above, is sucked in the rinsing mode rinse by means of the circulation pump via the first suction, in which for a backwash the direction of rotation of the circulating pump is reversed compared to the rinsing, so that rinsing is sucked by means of the circulation pump via the second suction line.
  • the method according to the invention makes it possible to differentiate between flushing operation on the one hand and backwashing operation on the other hand.
  • rinse liquor is conveyed via the second suction line to the circulating pump and from there back into the collecting pot.
  • the conveying direction reversal particles located on the inside of the fine filter, impurities and / or the like are replaced, which then accumulate in the lower part of the collecting pot, from where they can be pumped out and discarded by the sewage pump.
  • the process implementation according to the invention thus makes possible an automated cleaning of the fine filter arranged in the collecting pot, so that a cleaning to be carried out manually on the user side is preferably no longer necessary, but at least less frequent in contrast to the prior art.
  • the second intake pipe is blocked in the rinsing operation. This ensures that rinsing water does not unintentionally flow past the spray arm, which is actually to be acted upon in the bypass, back into the collecting pot during rinsing operation.
