Definitions

  • the present invention relates to a program-controlled dishwasher according to the preamble of claim 1 and a method for operating such a program-controlled dishwasher according to the preamble of claim 9.
  • Program-controlled dishwashers such as cleaning and disinfection devices, generally have an integrated softening device which serves to soften the water supplied.
  • the softening device contains a softener that must be regenerated using a salt solution or brine. This salt solution is produced in a salt container filled with table salt or regeneration salt. Regeneration of the softener extends the program duration if the regeneration cannot be carried out in parallel with the actual program sequence.
  • a washing machine in which regeneration of the softener can be carried out in parallel with the actual washing process.
  • the problem here is that the salt solution used for regeneration is conveyed by a total of two pumps, namely a pump which is arranged between a salt solution container and the softening device, and a waste water pump which is arranged behind the pump sump of the washing machine.
  • the saline solution to be pumped has highly corrosive properties and can lead to premature wear of the respective pumps.
  • a dishwasher is known in which the softening device is positioned directly at the water inlet.
  • the salt solution used for regeneration can be pressed through the softening device by water provided from the water pipe. This prevents contamination of the downstream pumps by saline solution.
  • the problem with this arrangement is that adequate protection of the drinking water network against possible back-contamination is not guaranteed. Because the dishwasher described in this European patent application does have a free outlet in the form of an interruption tank at the water inlet, but this is only arranged after the softening device.
  • the present invention has for its object to provide a program-controlled dishwasher in which a softening device can be regenerated during an ordinary washing program, but which has a longer service life and ensures better protection of the drinking water network than the dishwashers known from the prior art.
  • Such a dishwasher which is designed in particular as a program-controlled cleaning and disinfection device, has a water inlet, a free outlet in the water inlet (i.e. a free falling section or a free flow section in the water inlet) and a water reservoir behind the free outlet.
  • the water reservoir is used to keep water available for the operation of the dishwasher.
  • the free outlet creates a separation between the dishwasher's internal water network and a drinking water network, from which the water is drawn for the operation of the dishwasher.
  • the dishwasher is characterized in that a pump is arranged in the flow direction behind the water reservoir and a valve and distribution device are arranged behind the pump.
  • the pump only serves to pump a maximum of two types of water. On the one hand, it always serves to convey water that has reached the pump via the water reservoir. On the other hand, it can optionally also serve to convey water that has already been conveyed by the pump as cooling water through an optionally provided steam condenser of the dishwasher.
  • the pump does not pump brine or water mixed with a cleaning agent, but primarily water that is kept in stock in the water reservoir and - if the dishwasher has a steam condenser - also cooling water, if required, that the pump already has promoted (and originally came from the water reservoir).
  • An input of the valve and distribution device is in flow connection with the pump.
  • An outlet of the valve and distribution device has at least two lines. Each line is assigned at least one valve with which the corresponding line can be closed or opened. In this way it is possible, through the corresponding valve, to establish a flow connection between the respective line and the Manufacture or interrupt the pump.
  • the valve and distribution device can thus distribute the water conveyed by the pump to different lines and thereby specifically allow, limit or interrupt a water flow through the individual lines. Consequently, it is possible in a particularly simple manner to implement different water channels which are required for different program sections of the washing program carried out by the dishwasher.
  • valve and distribution device has at least two lines, it is also possible, on the one hand, to pump water from the pump to a processing chamber of the dishwasher and, on the other hand, water from the pump through a salt container in which regeneration salt is kept in stock, and then to pump it into a softening device . Consequently, it is possible to carry out a regeneration of a softener held in a softening device while a washing program is running. At the same time, the free outlet in front of the water reservoir ensures a separation between the water supply of the dishwasher and the drinking water network from which the dishwasher is fed with water.
  • the arrangement provided according to the invention also makes it possible to direct the excess salt solution, which is not required for regeneration, but was supplied to a softening device, directly into the waste water without having to flow through a pump again. It is also not necessary to pass this salt solution through the preparation chamber (washing chamber) of the dishwasher. This results in a lower risk of corrosion in the treatment chamber and in the pump used. Objects that are processed in the processing chamber are also subject to a much lower risk of corrosion than is the case with dishwashers known from the prior art.
  • the valve and distribution device has at least 3 lines, in particular at least 4 lines, in particular at least 5 lines, in particular at least 6 lines. In one variant, the valve and distribution device has 2 to 10 lines, in particular 3 to 9 lines, in particular 4 to 8 lines, in particular 5 to 7 lines. In one variant, the valve and distribution device has exactly 2 lines, in particular exactly 3 lines, in particular exactly 4 lines, in particular exactly 5 lines, in particular exactly 6 lines, in particular exactly 7 lines, in particular exactly 8 lines, in particular exactly 9 lines, in particular exactly 10 lines on.
  • the at least two lines of the valve and distribution device are at least two of the lines explained below: a cooling water line, an inner lumen line, a washing chamber line, a softener line, a salt container line or a waste water line.
  • a cooling water line is understood to mean a line with which the pump can be brought into flow connection with a steam condenser of the dishwasher. Then the water conveyed through the cooling water pipe serves as cooling water in the condenser, so that better condensation performance can be achieved there.
  • An inner lumen line is understood to mean a line with which the pump can be brought into flow connection with an inner lumen of a hollow instrument to be prepared in the dishwasher.
  • Hollow instruments such as medical and / or dental instruments have at least one inner lumen that is to be cleaned in the dishwasher.
  • the inner lumen line then serves to guide water through the inner lumen of such a hollow instrument.
  • a washing chamber line is understood to mean a line with which the pump can be brought into flow connection with an interior of a processing chamber of the dishwasher without having to flow through an inner lumen of an instrument to be processed.
  • the washing chamber line serves to introduce water into the washing or cleaning chamber of the dishwasher, for example to clean the outside of instruments or devices to be reprocessed.
  • a softener line is understood to mean a line with which the pump can be brought into flow connection with a softening device of the dishwasher. Then water pumped out of the water reservoir can only be pumped into the Softening device are softened before it is then conveyed as softened water into the preparation chamber of the dishwasher.
  • a salt container line is understood to mean a line with which the pump can be brought into flow connection with a salt container of the dishwasher.
  • the salt container itself is connected via a line to a softening device of the dishwasher. In this way, it is possible to convey water through the salt container line in order to transfer a brine from the salt container into the softening device, so that the softener (in particular a regeneration resin used for softening) which is kept in the softening device can be regenerated.
  • a waste water pipe is understood to mean a pipe with which the pump can be brought into direct flow connection with a waste water drain of the dishwasher.
  • a wastewater line can be used, for example, to pump excess water in the water reservoir straight into a wastewater outlet of the dishwasher without having to go through other flow paths of the dishwasher. This is particularly useful if the fill level in the water reservoir is too high or the water reservoir is to be completely emptied, for example after a washing program has been completed.
  • the softener line connects the valve and distribution device to the softening device on the one hand, and the softening device to the processing chamber of the dishwasher on the other. In this way it is possible to convey water from the water reservoir by means of the pump through the softening device to the treatment chamber and thus to supply the treatment chamber with softened water.
  • the salt container line connects the valve and distribution device to the salt container, the salt container to the softening device and the softening device to the waste water drain. It is then possible to pump saline solution from the salt container to the softening device through water pumped by the pump and to pump excess or no longer required saline solution directly from the softening device into the waste water outlet.
  • the pump itself only comes into contact with water from the water reservoir. The pump pushes the salt solution out of the salt container to the softening device without the pump having to come into contact with the salt solution.
  • the dishwasher has a steam condenser which is in flow connection with a cooling water line in the dishwasher. Then it is possible to convey water from the pump to the steam condenser through the cooling water line in order to ensure improved condensation in the condenser.
  • the cooling water line opens into the water reservoir via a free outlet. Then the cooling water can then be conveyed by the pump together with fresh water from the water reservoir, the cooling water being able to be conveyed into any line of the valve and distribution device.
  • the cooling water line does not open into the water reservoir via a free outlet, but is fluidly connected directly to an inlet of the pump.
  • the cooling water line in this variant can be connected to a line which connects the water reservoir to the pump. Then the pump can pump water from the water reservoir and cooling water from the cooling water pipe.
  • the dishwasher has a device for detecting a flow of the water conveyed by the pump.
  • This device for detecting a flow is arranged between the water reservoir and the pump or between the pump and the valve and distribution device.
  • Such a device for detecting a flow rate makes it particularly easy to determine various process parameters of the dishwasher. For example, a device for detecting the flow rate makes it particularly easy to determine whether a sufficient amount of water has already been pumped for a rinsing process. If this is the case, the rinsing program step can be ended and the next program step can be started. By detecting the flow, it is also particularly easy to determine whether regeneration of the softener in the softening device is necessary.
  • a device for detecting the flow can be used to determine the water consumption of the dishwasher. If a suitable flow measuring device does not determine a sufficient water flow despite the valves being open and sufficient pump output, this indicates that only an insufficient amount of water is flowing into the water reservoir. This can be due to the fact that the valve, which is arranged between the drinking water network and the water reservoir, is not fully open. Malfunctions in the dishwasher can also be detected by a flow measuring device. Can For example, a sufficient flow rate can be registered if the valves of some lines of the valve and distribution device are open, but if the pump output remains the same, only an insufficient flow rate is determined if the valves of one or more other lines of the valve and distribution device are open, this indicates Blockages in the corresponding lines. Then the corresponding lines can be cleaned in a targeted manner. Finally, the device for detecting a flow can also be used to determine the water consumption of the dishwasher.
  • the device for detecting a flow is a Coriolis mass flow meter, a swirl flow meter, a flow meter, an impeller meter, a magnetic-inductive flow meter, an orifice plate, an indirect volume meter, a helical wheel meter, a variable area flow meter , a dynamic pressure probe, a thermal mass flow meter, a turbine wheel flow meter, an ultrasonic flow meter, an immediate volume meter, a venturi flow meter, a displacement meter, a vortex flow meter, a vortex mass flow meter, a vortex flow meter or a Woltmann meter.
  • One aspect of the present invention relates to a method for operating a dishwasher according to the previous explanations.
  • a dishwasher has a water inlet, a free outlet in the water inlet and a water reservoir behind the free outlet. Water for the operation of the dishwasher is kept in stock in the water reservoir.
  • the method is characterized in that the water is sucked out of the reservoir by a pump arranged behind the water reservoir in the flow direction and is pressed by a valve and distribution device arranged behind the pump.
  • the pump only pumps water that is sucked out of the water reservoir by the pump, and optionally water that was passed through an optional steam condenser of the dishwasher.
  • the valve and distributor device is fluidly connected to the pump on its input side. On the output side, the valve and distribution device has at least two lines. Each line is assigned a valve, by means of which the corresponding line can be shut off or opened. In other words, the valve serves to establish or interrupt a flow connection between the corresponding line and the pump.
  • different lines can be selected through which the water is optionally pumped. These lines are each connected to the valve and distribution device.
  • the water can be conveyed from the pump through a cooling water line to a steam condenser of the dishwasher. It can also be conveyed through an inner lumen line to an inner lumen of a hollow instrument to be processed in the dishwasher.
  • the pump conveys the water through a washing chamber line to an interior of a processing chamber of the dishwasher, without the water having to flow through an instrument to be processed.
  • the water can also be conveyed from the pump through a softening line to a softening device in the dishwasher. The water extracted can be softened there.
  • the pump can also convey the water through a salt container line to a salt container in the dishwasher. It is also possible that the pump conveys the water through a sewage line to a sewage outlet of the dishwasher. Which of the respective lines is actually supplied with water by the pump depends on which valves of the valve and distributor device are open and which are closed. In addition, all of the aforementioned lines do not necessarily have to be present in the dishwasher. Rather, any subset of the aforementioned lines can be present, with at least two lines coming from the valve and distribution device.
  • the water is pumped through the cooling water line in a circuit through the steam condenser. It is therefore possible that the pump conveys water from the water reservoir to the steam condenser, where it acts as cooling water for improved condensation. The heated water is then pumped back to the pump. It can initially flow into the water reservoir via a free outlet in order to be pumped from there again. However, it is also possible for the cooling water to be led into a line which connects an outlet of the water reservoir to an inlet of the pump, so that the cooling water can be conveyed directly by the pump bypassing the water reservoir. By conveying cooling water in this way in a cooling water circuit, a significantly improved condensation performance within the steam condenser can be achieved.
  • This promotion of cooling water in the cooling water circuit can take place parallel to the other program sections. For example, it is possible that a cleaning program is carried out in a processing chamber of the dishwasher, the condenser is simultaneously cooled with cooling water and the softening device is regenerated by a salt solution. All of these process steps can be carried out with the pump and the valve and distribution device can be easily accomplished. This results in a great time advantage for the user of the dishwasher or the operator of the claimed method, since previously sequential process steps can now be carried out in parallel and, moreover - for example due to an improved condensation performance within the steam condenser - take less time than in the prior art . In addition, the circulation of cooling water within the cooling water line leads to a significant reduction in cooling water consumption, so that corresponding costs can be saved.
  • a regeneration process of a softening system of the dishwasher is carried out independently of other method steps of a preparation process that takes place in the dishwasher or a preparation chamber of the dishwasher. For example, it is possible to first carry out a first phase of the treatment process and then a second phase of the treatment process, while the softener in the softening system is continuously regenerated. It is also possible to carry out the regeneration of the softener only during a partial period of a treatment process.
  • the pump conveys the water in order to push a salt solution out of the salt container to the softening device.
  • This salt solution is then used in the softening device to regenerate a softener.
  • the water conveyed by the pump then also ensures that saline solution or excess saline solution that is no longer required is pumped directly from the softening device into a waste water drain. Direct contact between the saline solution or excess saline solution and the pump is not necessary. Rather, only water flows through the pump, which extends its lifespan and reduces its risk of failure.
  • the pump conveys the water against the completely or partially closed valve and distribution device depending on a fill level of the water in the water reservoir.
  • the valve and distribution device is partially closed if not all of the existing valves are open or if at least one existing valve is not fully open.
  • the valve and distributor device is completely closed when all valves of the valve and distributor device are closed.
  • Such a discrepancy between the pumped water and the inflowing water can be caused, for example, by a fluctuating line pressure in the water inlet.
  • the possibility of conveying against the completely or partially closed valve and distribution device makes it independent of such a fluctuating line pressure in the water inlet.
  • Figure 1 a schematic diagram of an embodiment of a dishwasher.
  • the Figure 1 shows a schematic circuit diagram of the liquid lines of a dishwasher 1.
  • This dishwasher 1 has a water inlet 2 connected to a drinking water network with a free outlet 3.
  • a water reservoir 4 is connected to a booster pump 6 via a first line 5.
  • This pressure booster pump 6 only conveys water which is fed to it from the water reservoir 4 via the first line 5.
  • a valve and distribution device 7 is arranged downstream of the booster pump 6.
  • This valve and distribution device 7 has a plurality of lines, namely a cooling water line 8, an inner lumen line 9, a washing chamber line 10, a softening line 11, a salt container line 12 and a waste water line 13.
  • a valve is arranged, through which the respective line can be opened or closed completely or partially. In this way, it is possible to specifically convey water that is conveyed by the booster pump 6 through individual lines connected to the valve and distribution device 7.
  • the cooling water line 8 connects the booster pump 6 to a steam condenser 14, in which steam or warm, moist exhaust air from a treatment chamber 15 is condensed.
  • the cooling water line 8 is passed through the steam condenser 14 and opens into the water reservoir 4 via a free outlet 16. This makes it possible to pump cooling water by means of the pressure booster pump 6 in a circuit through the cooling water line 8 and through the steam condenser 14 and in this way one to achieve increased condensation capacity of the steam condenser 14 with a simultaneously reduced cooling water requirement.
  • the inner lumen line 9 creates a flow connection between the booster pump 6 and an adapter rail 17, which has a large number of adapters 18, only a few of which are provided with the corresponding reference numerals. These adapters 18 are used to connect hollow body instruments to the adapter rail 17. Then water, which is led through the inner lumen line 9, can flow through the adapter rail 17 and the adapters 18 into the inner lumens of the hollow body instruments connected to the adapters 18 and clean these inner lumens. In this way, internal cleaning of medical and / or dental hollow body instruments is possible, which are processed, in particular cleaned and disinfected, in the processing chamber 15 of the dishwasher 1.
  • the washing chamber line 10 establishes a flow connection between the booster pump 6 and the processing chamber 15 without the water that is passed through the washing chamber line 10 having to flow through an inner lumen of a hollow body instrument to be processed in order to get into the washing chamber 15. Water, which is conveyed through the washing chamber line 10, is thus suitable for cleaning the outside of instruments or other objects which are to be processed in the processing chamber 15.
  • the washing chamber line 10 could, for example, be connected to a lower rinsing arm 19 and / or an upper rinsing arm 20 of the treatment chamber 15 in order to introduce water into the treatment chamber 15 in this way.
  • the softener line 11 establishes a flow connection between the booster pump 6 and a softening device 21, in which a softener is provided for softening water.
  • the softening line 11 also leads from the softening device 21 further into the treatment chamber 15. It is thus possible to convey water through the softening line 11 first to the softening device 21 and then to the processing chamber 15 and in this way to the softening device 21 softening. In this way it is possible to supply softened water to the treatment chamber 15.
  • the softener line 11 can open directly into the processing chamber 15, be connected to the adapter rail 17 or be connected to at least one of the two rinsing arms 19, 20.
  • the salt container line 12 establishes a flow connection between the booster pump 6 and a salt container 22.
  • the salt container line 12 establishes a flow connection between the salt container 22 and the softening device 21. Consequently, it is possible to pump water through the salt container line 12, which then presses a salt solution from the salt container 22 into the softening device 21, where the salt solution is used to regenerate the softener of the softening device 21. After the regeneration process, the salt solution that is no longer required - just like excess salt solution - can be pressed through a further section of the salt container line 12 and flow into a waste water outlet 23.
  • the waste water line 13 establishes a flow connection between the pressure booster pump 6 and the waste water outlet 23, so that water from the water reservoir 4 can also be conducted directly into the waste water outlet 23 of the dishwasher 1 by means of the pressure booster pump 6.
  • a pump sump 24 is arranged below the treatment chamber 15, in which used rinsing and cleaning liquid collects as waste water in the course of a treatment process. From this pump sump 24, the waste water accumulated there can be pumped into the waste water outlet 23 of the dishwasher 1 by means of a waste water pump 25.
  • the specific arrangement of the water reservoir 4, the pressure booster pump 6 and the valve and distribution device 7 makes it possible to carry out various processes (such as the preparation of objects in the preparation chamber 15, the condensation of steam in the steam condenser 14 and the regeneration of softener in the softening device 21 ) to be carried out in parallel, at the same time ensuring a sufficiently high pressure within the individual lines of the dishwasher 1 and ensuring a high level of drinking water safety by decoupling the line network of the dishwasher 1 from a drinking water network which is used for the water supply.
