  • the fluid overflow protection of the main reservoir can stop the supply of water to the dishwasher when more fluid emerges from the washing container than the respective intermediate reservoir can accommodate.
  • the bottom assembly of the dishwasher in particular domestic dishwasher, is also referred to as the base support of the dishwasher and represents the connecting part between a substrate, such as a floor or the bottom of a Einbaunische in a kitchen furniture, and the washing compartment of the dishwasher.
  • the washing compartment is above the floor assembly on this attached.
  • the fluid collecting device preferably represents the lowermost end of the dishwasher and serves with its one or more intermediate reservoir and its main reservoir for receiving fluid, in particular Spülflottentellkeit from the dishwasher and / or other fluid-carrying component such as a circulating pump, drain pump, fluid circuit line, etc .... due to leakage and / or leakage through at least one overflow pipe when a maximum permissible level is exceeded.

  • the guide channel between the respective intermediate reservoir and the main reservoir serves as an overflow from a certain amount of fluid, in particular rinsing fluid, in the respective intermediate reservoir, which is greater than its capacity.
  • the bottom region of the respective intermediate reservoir is formed by the lower region of the intermediate reservoir.
  • the floor area can be designed differently. Thus, the floor area may be flat, but also uneven, for example, slightly curved, be formed.
  • the side wall of the intermediate reservoir serves, so to speak, as a barrier, which retains a certain amount of fluid in the intermediate reservoir, in order to open the possibility that this fluid evaporates in the intermediate reservoir due to the ambient conditions.
  • the fluid collecting device is designed as a flat bottom plate.
  • the main reservoir and the one or more intermediate reservoirs are preferably formed as recessed wells.
  • the respective intermediate reservoir is preferably designed as an evaporation tray.
  • each intermediate reservoir is higher than that of the main reservoir.
  • a dishwasher is particularly preferred which is characterized in that the bottom region of the respective intermediate reservoir is arranged closer to the washing container of the dishwasher than the bottom region of the main reservoir. That is to say, the bottom area of the respective intermediate reservoir is arranged vertically higher than the bottom area of the main reservoir. This creates a gradient, so that the fluid emerging from the intermediate reservoir can automatically run into the main reservoir.
  • the intermediate reservoir and the main reservoir are preferably arranged on different levels.
  • the bottom region of the main reservoir is preferably arranged at one of the lowest points of the fluid collecting device.
  • the fluid overflow protection unit is advantageously provided at the lowest point of the main collecting reservoir.
  • the respective intermediate reservoir may in particular be arranged in a stepped manner above the main collecting reservoir, similar to a cascade.
  • integral component in the sense of the invention means that neither the intermediate reservoir nor the main reservoir must be subsequently arranged as additional elements on the bottom module or on the bottom plate of the bottom module, but already during the manufacture of the bottom plate part of the bottom plate. That is to say, integral means that the respective intermediate reservoir and the main reservoir are produced directly during the production of the base plate of the base assembly. This is preferably done by a casting process, in particular an injection molding process. Alternatively, the bottom plate of the bottom assembly including the intermediate reservoir and the main reservoir can also be produced by a deep-drawing process.
  • the advantage of such a design of the bottom plate is in addition to the low production costs, since no separate reservoirs must be made in the elimination of the mounting of one or both reservoirs on the bottom plate of the bottom assembly. That is, a complex and time-consuming attachment of the reservoir to the bottom plate is eliminated.
  • the bottom plate may be formed as a separate component of the floor assembly or as an integral part of the floor assembly. In particular, it may be expedient to produce the base assembly including the bottom plate as a fluid collecting device made of plastic. This allows a simple and inexpensive production.
  • the guide channel is formed tapering from the intermediate reservoir to the main reservoir.
  • the guide channel is advantageously designed as an open channel. But it can also have a closed hollow profile shape, such as a pipe. Because of the guide channel tapers tapered to the main reservoir, the overflowing from the intermediate reservoir water can be directed better targeted. That is, the water emerging from the guide channel in the main reservoir can be guided exactly where, for example, the float of the fluid overflow protection is arranged.
  • the taper of the guide channel may be formed, for example, cone-shaped. If the guide channel is formed as a hollow profile, the taper can be formed by a constant reduction of the cross section of the guide channel to the main reservoir.
  • a dishwasher wherein the first end of the guide channel, which is associated with the respective intermediate reservoir, is arranged closer to the washing container, as a second end of the guide channel, which is associated with the main reservoir, wherein the distance of the guide channel to the washing container from first end to the second end of the guide channel preferably increases permanently.
  • the guide channel of the guide channel is arranged inclined. That is, the guide channel has a slope from the respective intermediate reservoir to the main reservoir. The overflowing from the intermediate reservoir in the guide channel fluid is due to the gradient of the guide channel quickly and purposefully the main reservoir, in particular the fluid overflow protection of the main reservoir, fed.
  • Located closer to the washing container means that the distance of the first end of the guide channel to the washing container is less than the distance of the second end of the guide channel to the washing container, which opens into the main reservoir.
  • the overflowing from the respective intermediate reservoir fluid therefore runs automatically due to its gravity in the direction of a specific point, in particular in the vicinity of the fluid overflow protection unit, in the main collection reservoir.
  • the guide channel can be designed in various ways.
  • the guide channel between the respective intermediate reservoir and the main reservoir of the dishwasher may alternatively be referred to as a tapered Well be formed in a partition wall between the two reservoirs.
  • the two fluid collecting reservoirs can be arranged directly adjacent to each other, separated only by a partition wall.
  • the guide channel is not elongate in this advantageous embodiment, but is formed by a depression in the partition wall between the two reservoirs.
  • the depression is provided at the intermediate reservoir in such a way that the fluid flowing over from the intermediate reservoir is supplied to a specific point of the main reservoir.
  • the recess may in particular be a recess in the side wall of the intermediate reservoir or container. Due to the tapered shape of the depression of the directed inflow of the overflowing water is ensured to the main reservoir.
  • the bottom region of the respective intermediate reservoir has a flat horizontal extension or an approximately horizontal horizontal extension.
  • Such a configuration of the bottom region of the intermediate reservoir of the dishwasher ensures that the fluid emerging from the washing container is distributed as uniformly as possible over the entire bottom region of the intermediate reservoir, so that rapid evaporation of the water can occur.
  • An approximately flat horizontal extent means in the sense of the invention that the bottom area can have only a slight or no inclination, for example between 0 ° and 2 degrees, with respect to a horizontal plane. It may be particularly preferred if the lowest point of the bottom portion is not associated with the first end of the guide channel, but from this has a minimum distance. As a result, sump products, if they occur because not store directly in front of the guide channel, so that the entry into the guide channel for the fluid remains free.
  • the ratio of the longitudinal and / or transverse extent of the collecting surface of the respective intermediate reservoir to its depth more than 3: 1, in particular between 5: 1 and 8: 1, preferably more than 10: 1, too choose.
  • a dishwashing machine is particularly preferred in which the ratio of the planar horizontal extension or the approximately planar horizontal extension the bottom area of the intermediate reservoir to the depth of the intermediate reservoir is more than 5: 1, in particular more than 10: 1. That is, the horizontal extent, based on an x, y, z coordinate system, the extent in an x-direction and a y-direction, is significantly greater than the depth of the intermediate reservoir, ie the extension of the intermediate reservoir in a direction perpendicular to the x - and y-direction extending z-direction. This ensures that the intermediate reservoir is not high, but is advantageously flat.
  • the bottom region of the intermediate reservoir is therefore preferably formed over a large area, so that in the intermediate reservoir from the washing and / or other fluid-carrying component supplied fluid can evaporate as quickly as possible.
  • a flat horizontal extension of the floor area advantageously ensures that the water is distributed evenly in the floor area.
  • Another advantage of such a design of the bottom region of the intermediate reservoir is that the intermediate reservoir does not have to have a large depth, which in turn keeps the height of the fluid collecting device, in particular the bottom plate, the bottom assembly of the dishwasher, in particular the domestic dishwasher low.
  • a flat formed bottom region of the intermediate reservoir may preferably extend over a large part of the base area of the bottom plate of the bottom assembly. The larger the bottom area of the intermediate reservoir is formed, the lower the depth of the intermediate reservoir can be formed and the faster can fluid that has leaked from the washing and fed to the intermediate reservoir, evaporate in the intermediate reservoir.
  • a filter element covering the cross-section of the guide channel may optionally be provided on the guide channel.
  • a dishwasher is particularly reliable in terms of fluid overflow protection.
  • the filter element filters contaminants out of the leakage fluid and / or overflow fluid that float on the surface of the leaked fluid. It can always happen that contaminants due to their composition float on the surface of the fluid collected in the intermediate reservoir and do not settle or settle as bottom products at the bottom area of the intermediate reservoir. So that these do not pass from the intermediate reservoir to the main reservoir and thus to the fluid overflow protection in the event of an overflow of the fluid, the filter element covering the cross section of the guide channel is provided. It can the filter element can be designed differently large. For example, the filter element may be a relatively coarse-meshed grid that retains larger contaminants.
  • a dishwasher in which according to a further expedient embodiment a closable discharge opening is provided in a side wall of the floor assembly, which faces the intermediate reservoir, allows easy removal of bottoms left in the intermediate reservoir.
  • a closable emptying opening is provided on the front wall of the floor assembly, which is arranged below the door of the washing compartment of the dishwasher.
  • the fluid absorption capacity of the intermediate reservoir would gradually decrease, so that even with very small quantities of leakage fluid and / or overflow fluid, an overflow of the fluid to the main reservoir and, consequently, unnecessary triggering of the fluid overflow safety device would occur ,
  • a dishwasher may be expedient in which two or more intermediate reservoirs, each with a guide channel, are provided between each intermediate reservoir and the main reservoir. That is, improperly leaking fluid from the purge bin may be supplied to two or more intermediate reservoirs. In this way, the bottom area of the intermediate reservoirs, ie the size of the bottom areas of all intermediate reservoirs, can be increased again, so that an even more effective evaporation of the overflow and / or leakage fluid can take place.
  • Each intermediate reservoir is connected via at least one guide channel to the main reservoir of the collecting device, in particular the bottom plate of the base assembly.
  • the guide channels between the intermediate reservoir and the main reservoir can be designed differently. Preference is given to all intermediate reservoirs arranged higher than the main reservoir on the bottom plate.
  • the guide channels advantageously all have a gradient towards the main collecting reservoir, so that fluid that overflows from the intermediate reservoirs can, due to its gravity, be supplied to the main collecting reservoir in a rapid and targeted manner.
  • the bottom plate of the bottom assembly of the dishwasher is preferably made of plastic or metal.
  • Complicated shapes of the bottom plate are preferably made of plastic, for example by a casting method, in particular by an injection molding process.
  • the bottom plate can be produced by a deep-drawing process. If the bottom plate is an integral part of the bottom assembly, the entire bottom assembly is preferably made by a casting process or a deep drawing process.
  • This channeling i.
  • cross-linking or communicating connection between the intermediate reservoirs allows excess fluid to be distributed from the respective intermediate reservoir to one or more other intermediate reservoirs. It can thus be avoided that an intermediate reservoir whose capacity is too small to receive a from the washing and / or other fluid-carrying component, does not overflow into the main reservoir. As a result, it is possible to avoid that fluid enters the main reservoir in an unnecessary manner and addresses its fluid overflow protection unit there.
