Definitions
- the invention relates to a water-conducting domestic appliance, in particular laundry treatment appliance for washing and / or drying laundry, with a treatment area and a channel arrangement, via which a liquid flow into the treatment area is feasible, wherein at least a part of the channel arrangement is designed as a siphon, wherein a control valve and a controller are provided and wherein the controller controls at least the control valve to control the flow of liquid through the channel assembly, and wherein a drainage means is provided, which serves to partially empty the siphon.
- the invention relates to the field of washing machines and washer-dryers.
- a generic water-conducting household appliance with a water supply device is described.
- a treatment area is provided which has a feed point.
- the water supply device is connected to the feed point of the treatment area, wherein the water supply device has a siphon.
- the siphon has the function here that a certain level of the water mask is specified. This function results from the fact that the siphon serves as a drainage means to remove excess liquid from the siphon and to partially empty it, namely to a level given by placing the corresponding inlet of the siphon. In this way, on the one hand, a sufficient amount of water in the water supply device remain to form a reliable vapor barrier for a washing and / or drying cycle.
- an undesirable outflow of water from the water supply device is prevented. Specifically, it is prevented that, for example, when opening the door of the household appliance water due to the pressure equalization exits the water supply device and enters the treatment area.
- the water supply device thus forms a reliable vapor barrier, at the same time an undesirable entry of water from the vapor barrier is prevented in the treatment area.
- a part of the generally scarce space is required anyway and also increase the necessary components for this cost.
- the object of the invention is to provide a water-conducting household appliance, which has an improved structure with respect to a targeted Notatmungsfunktion or ventilation.
- a water-conducting domestic appliance in particular laundry treatment appliance for washing and / or drying laundry, with a treatment area and a channel arrangement, via which a liquid flow into the treatment area can be guided, wherein at least a part of the channel arrangement is designed as a siphon wherein a control valve and a controller are provided and wherein the controller controls at least the control valve to control the flow of liquid through the channel assembly, and wherein a drainage means is provided, which serves to partially empty the siphon.
- the controller controls the check valve to partially fill the siphon with the liquid flow until the siphon is blocked from passage of gas.
- the emptying means additionally serves to at least substantially empty the siphon, and finally, in a release mode, the controller controls the control valve and the draining means to drain the siphon of liquid until the siphon is open to allow passage of gas.
- the emptying means is a siphon, which serves for at least substantially emptying of the siphon, and that the control in the release mode, the control valve controls so that the liquid flow a rising portion and a descending portion of the Suction lifter flows through.
- the emptying agent is purely passive, since it is activated only by appropriate filling of the siphon. It is therefore advantageous that the siphon is provided as a drainage means.
- the combination of siphon and siphon can thus be realized a purely hydraulic operation, which allows reliable operation over the life of the household appliance.
- the control valve can be used in this case instead of a usually provided anyway check valve or the like, so that the number of required components and the associated requirement for space are optimized. It is also advantageous that the control in the release mode controls the check valve so that the liquid flow flows through an ascending section and a descending section of the siphon. In the release mode, for example, a larger amount of fresh water or a mixture of fresh water and a treatment agent can be led into the treatment area.
- the control switches the shut-off valve according to the lock-up mode.
- the controller advantageously actuates the check valve such that the liquid flow partially fills a rising portion of the siphon with liquid while leaving a descending portion of the siphon free. As a result, the siphon is then partially filled with liquid so that a gas-tight seal formed and passage of gas is excluded.
- the siphon is formed by a siphon line, that the siphon has an outlet opening which is arranged at least approximately at a lowest point of the siphon, and that the siphon line opens on the one hand at the outlet opening into the siphon.
- the siphon pipe can also open directly into the treatment area. In this way, in particular a large cross section of the siphon is made possible, which allows a sufficient exchange of air in the open state of the siphon. The siphon is then emptied reliably via the siphon line in accordance with the release mode.
- At least one further siphon line it is also preferable for at least one further siphon line to be provided, that the siphon has at least one further outlet opening, which is arranged at least approximately at a lowest point of the siphon, and that the further siphon line opens into the siphon at the further outlet opening.
- the siphon is formed by the channel arrangement.
- the cross-section can be partially reduced to ensure the Saugheber bin.
- the number of required components can be further reduced and thus the assembly effort and space requirements can be further reduced.
- An alternative preferred embodiment of the invention is characterized in that the emptying means is a pump, that the treatment area has an outlet which is connected via a drainage channel to the pump, that the channel arrangement has a supply line which between the outlet and the pump in the Outflow channel opens, and that the siphon is partially formed by the supply line and partly by the drainage channel.
- the feed device for treatment liquid is brought together with the drain device, wherein the supply of treatment liquid to the tub takes place on the expiration.
- This emptying agent is not passive, since it requires the operation of the control by the control. However, it does not increase the complexity of the household appliance, as it is an already required component.
- At least one sensor is provided on the channel arrangement, which serves for detecting the partial filling of the siphon.
- the siphon ensures a gas seal and thus an escape of possibly toxic gases, such as ozone, is prevented.
- this can be used to generate a signal for the control, which causes the interruption of the liquid flow through the control valve in the lock-up mode.
- a flow meter which serves to detect the amount of liquid for the partial filling of the siphon.
- This flow meter may be required anyway for other functions of the water-conducting household appliance, so that this embodiment is cost-neutral.
- Fig. 1 is a water-conducting household appliance in a partial, schematic sectional view according to a first embodiment
- Fig. 2 shows a water-conducting household appliance in a partial, schematic sectional view according to a second embodiment
- Fig. 3 is a water-conducting household appliance in a partial, schematic representation according to a third embodiment.
- Fig. 1 shows a water-conducting household appliance 1 in a partial, schematic sectional view according to a first embodiment.
- the household appliance 1 can be configured in particular as a laundry treatment appliance and serve for washing and / or drying laundry.
- the household appliance 1 can be configured as a washing machine or washer-dryer.
- the household appliance 1 of the invention is also suitable for other applications, in particular, it may be configured as a dishwasher.
- the household appliance 1 has a treatment area 2, which is surrounded by a container 3.
- the container 3 may be configured for example as a tub 3.
- Within the tub 3 may be, for example, a washing drum or the like, which serves to receive laundry.
- the household appliance 1 has a channel arrangement 4, via which liquid can be guided into the treatment area 2.
- liquid can be conducted into the treatment area 2 via the channel arrangement 4.
- liquid is to be understood generally.
- a powdered detergent can be rinsed with the fresh water in the treatment area 2, wherein the complete dissolution of the powdered detergent is optionally also only in the treatment area 2.
- the supply of the fresh water takes place at a fresh water connection 5.
- the fresh water 5 is first fed via a fresh water line 6 to a flow meter 7. After the flow meter 7, the fresh water passes through a free air gap 8 in a dispensing tray 9.
- a liquid flow is generated by the channel arrangement 4.
- the flow meter 7 is connected via a signal line 10 to a controller 11.
- the flow meter 7 detects the amount of liquid that is guided as a liquid flow in the channel assembly 4.
- the detected amount of liquid can then be evaluated by the controller 11.
- the controller 11 is connected via a control line 12 to a control valve 13 arranged in the fresh water line 6.
- the control valve 13 is configured as a throttled control valve 13 in this embodiment. However, the control valve 13 could also be configured without throttling. By operating the control valve 13, the supply of fresh water at the beginning of a program sequence can be made possible and interrupted according to the individual courses and released again for conventional operation.
- the controller 11 can control the control valve 13 for this purpose in a conventional manner.
- the channel arrangement 4 has a siphon 15.
- a part of the channel arrangement 4 is designed as a siphon 15.
- the channel assembly 4 may be formed of a rigid plastic.
- two injection molded parts can be welded together to form the channel assembly 4 with the siphon 15.
- the siphon 15 may also be formed by a flexible piece of hose, which is bent accordingly.
- the siphon 15 is configured in this embodiment as a U-shaped siphon 15.
- the siphon 15 has a lowest point 19.
- the minimum level 18 is at least approximately at the lowest point 19 of the siphon 15.
- the siphon 15 has an outlet opening 20, through which one end 21 of a siphon 22 in the siphon 15 protrudes.
- the siphon 22 is formed by a siphon pipe 22 in this embodiment.
- the siphon 22 has an ascending portion 23 and a descending portion 24.
- the siphon 22 opens at the minimum level 18 on the one hand into the siphon 15.
- the siphon 22 also opens at its end 25 below the minimum level 18 of the siphon 15 into the treatment area 2.
- the liquid remaining in the siphon 15 is continuously conveyed into the treatment area 2 by the siphon 22 until the minimum level 18 has been reached.
- the siphon 15 is then at least largely emptied, so that there is an air connection between the treatment area 2 and at the free air gap 8 with the environment.
- the ventilation therefore comes about the dispenser 9.
- 9 suitable openings may be provided on the dispenser tray.
- this ventilation is usually unfavorable.
- steam, a treatment gas, in particular ozone, foams resulting during washing or the like can pass through the open siphon 15 to the dispensing tray 9 and thus into the environment. Therefore, the controller 11 is configured to control the check valve 13 in a lock-up mode so that partial filling of the siphon 15 is effected by the liquid flow.
- an amount of liquid is filled in the siphon 15, which fills the siphon 15 to a middle level 17.
- the middle level 17 is to be understood as an example and there is also a certain tolerance in the supply of the liquid flow or the amount of liquid for the partial filling of the siphon.
- this amount is chosen to be sufficiently large so that the liquid level exceeds the minimum level 18 on the one hand so far that the siphon 15 is closed.
- the amount of liquid is not so large that the maximum level 16 is reached. That is, the average level 17 has a sufficient distance to the maximum level 16. Because on reaching the maximum level 16 would be due to the law of communicating tubes, the rising portion 23 of the siphon 22 filled up to the top point 30, whereby liquid in the descending section 24 passes and it comes in a further supply of fresh water also for the start of the Saugheber bins the siphon 22.
- the partial filling of the siphon 15 up to the middle level 17 can take place via a flow rate control.
- the amount of liquid guided into the siphon is detected by the flow meter 7 and, in accordance with the detected quantity of liquid, the controller 11 timely deactivates the liquid supply.
- Another possibility is a time-dependent control, in which the control valve 13 is open completely or to a defined part, so that after a certain time, a partial filling of the siphon 15 is reached.
- the detection of the level of the siphon 15 directly or indirectly via a sensor 35 is arranged in the ascending portion 23 of the siphon 22. In this way, indirectly, the level of the rising portion 27 of the siphon 15 can be detected.
- the controller 11 can switch the control valve 13 into the locked state as a result of this detection. It is also possible to arrange the sensor 35 in the siphon 15 in order to detect the liquid level directly in the siphon 15. In this case, the sensor 35 is preferably arranged in the ascending section 27 of the siphon 15. In this embodiment, the air inlet and the air outlet via the handle of Ein Stammschale 9 can take place. However, other embodiments are conceivable. In this embodiment, the siphon 15 may have a large passage cross section, so that a particularly good exchange of air can be ensured. Thus, the siphon 15 can selectively fill and empty targeted. At a partial filling up to the middle level 17, the gas passage is blocked.
- the siphon 15 can then be emptied specifically.
- the emptying can thus be done by supplying a defined amount of water.
- a running water flow that is a large amount of water, is not necessary for this.
- the emptying of the siphon 15 take place.
- the emergency respiration function is then fulfilled because the empty siphon 15 is permeable to gas. Due to the design, the water filled up to the middle level 17 remains arbitrarily long and without loss in the siphon 15. Continuous refilling is therefore not necessary.
- the individual switching states of the siphon 15 can thus be maintained over a long period of time.
- the siphon 15 can also be emptied by a current liquid flow, in which any, but sufficiently large amount of water is passed through the channel assembly 4, wherein the inflowing flow is greater than the simultaneously withdrawn through the siphon 22 volume flow. After stopping this liquid flow, the siphon 22 then at least substantially empties the siphon 15.
- Fig. 1 also schematically another siphon line 36 is shown with an ascending portion 37 and a descending portion 38 which forms a further siphon 36.
- two suction lifters 22, 36 can be provided in parallel.
- a further sensor 40 may be provided, which is arranged in the region of the minimum level 18 in the siphon 15. The sensor 40 is connected to the controller 11 via a signal line 41. In this way it can be reliably detected whether the siphon 15 is emptied.
- the controller 11 By the sensors 35, 40 and the error-free operation or the occurrence of a fault can be detected by the controller 11. If appropriate, this can take place taking into account the signal from the flow meter 7 and optionally further signals. For example, from the period of time that the siphon 22 needs to lower the liquid level from the middle level 17 to the minimum level 18, a possible increasing blockage of the siphon 22 may be inferred. For this purpose, if appropriate, a sensor can be provided which detects the maximum level 16. If the operating speed of the siphon 22 is no longer sufficient, then the controller 11 may issue an error.
- the middle level 17 is provided with a large tolerance range, the partial filling of the siphon 15 can take place without the flow meter 7 or without using the signal of the flow meter 7 over the time control. Special is This also makes possible a realization in the case of water-conducting domestic appliances 1, which have no or no sufficiently accurate flow meter 7.
- Fig. 2 shows a water-conducting household appliance in a partial, schematic sectional view according to a second embodiment.
- the siphon 22 is formed by the channel assembly 4.
- the ascending section 23 of the siphon 15 is at the same time the ascending section 27 of the siphon 22.
- the descending section 24 of the siphon 22 is equal to the outlet section 29.
- the uppermost point 30 of the siphon 22 is in the section 28 in this embodiment which connects the ascending section 23 with the descending section 24 and the ascending section 27 with the drain section 29, respectively.
- the sensor 35 is arranged in the ascending portion 27 of the siphon 15 in this embodiment.
- the siphon 15 in FIG. 2 is partially filled with liquid 42.
- a level 43 of the liquid 42 is thereby approximately at the middle level 17.
- the sensor 35 responds, so that via a signal line 34 the controller 11 is informed that the siphon 15 is sealed gas-tight.
- the controller 11 can also reliably check this state.
- the emptying of the siphon 15 takes place after passing through liquid both through the siphon 15 and through the Kanalanord- 4. Since the channel assembly 4 forms the siphon 22, it comes after passing through water to a substantial emptying of the siphon 15. If a gas-tight closure is desired, then an amount of liquid 42 is fed into the siphon 15, as illustrated in FIG.
- the emptying of the siphon 15, which is filled with a certain amount of liquid, as it corresponds to the level 43, for example, can also be done by a defined addition of a comparatively small amount of water. For this purpose, so much liquid is supplied that the siphon 15 is filled to the uppermost point 30 and liquid flows over the descending portion 24 of the siphon 22.
- the siphon 22 is set in motion, so that it comes to emptying of the siphon 15.
- the siphon 15 can effectively be used as a siphon 22.
- a line cross-section of the channel arrangement 4 can be reduced at least in the area of the siphon 22 with respect to the remaining channel arrangement 4.
- the line cross-section is not chosen too large here, otherwise a ventilation of the siphon 22 could result backwards over the drain section 29, which makes the siphoning effect null. But even with a comparatively large line cross-section can at least be detected via the sensors 35, 40, whether the desired switching state is reached.
- the controller 11 in the lock-up mode, the control valve 13 to control so that a partial filling of the siphon 15 is effected by the liquid flow.
- the controller 11 in the release mode the control valve 13 to control so that the liquid flow through the ascending portion 23 and the descending portion 24 of the siphon 22 and it comes to emptying of the siphon 15.
- the release mode can be effected both by a running liquid flow and by adding a certain amount of liquid to the liquid 42 illustrated in FIG. 2, whereby the siphon 22 is set in motion.
- the controller 11 may also perform preventive or remedial actions to prevent possible errors from the outset. Such a mistake may be, for example, a possible blockage of the siphon 22 by detergent residues, a biofilm or the like. The fault can be counteracted by a regular or targeted triggered, in particular periodic, activation of the siphon 22.
- FIG. 3 shows a water-conducting domestic appliance in an excerptional, schematic representation according to a third exemplary embodiment.
- a conduit 50 of the channel arrangement 4 is provided, which is connected at a connection point 51 with the ascending portion 27 of the channel arrangement 4 and with a portion 52.
- the ascending section 27 and the section 52 are hereby sections 27, 52 of a drainage channel 53, which is connected to the tub 3.
- the tub 3 has an outlet 54 to which the drainage channel 53 is mounted.
- the drainage channel 53 leads to a pump 55.
- a channel 56 is provided, which can be connected, for example, to a drain 57 of a domestic installation.
- the ascending portion 27 of the siphon 15 is formed by a portion 27 of the drainage channel 53.
- the mixture of fresh water and detergent then passes via the line 50 and the ascending section 27 at the outlet 54 into the tub 3.
- the guided into the tub 3 amount of liquid defines the maximum level or a high level 16 'for the siphon 15th
- the joint 51 is located between the outlet 54 and the pump 55, wherein the pump 55 is in the operating position below the outlet 54. Between the outlet 54 and the connection point 51 results in a middle level 17, wherein over the length of the rising portion 27, a more or less large tolerance range can be specified. Between the connection point 51 and the pump 55 is the minimum level 18.
- the pump 55 ensures this pumping the liquid from the channel assembly 4 to the minimum level 18th
- the average level 17 is below the middle Level 17.
- the middle level 17 is below the outlet 54, so that there is no more liquid in the tub 3.
- the channel assembly 4 is emptied to the minimum level 18. Since the lowest point 19 of the siphon 15 is above the minimum level 18, thus an emergency ventilation function is ensured.
- the pump 55 may be configured depending on the application.
- the pump 55 may be configured as an electrically operated drain pump 55.
- the pump 55 may also be designed as a venturi 55, which is operated indirectly via the wastewater stream. It is also possible to realize a pumping system.
- the medium level 17 can also be achieved by adding a certain amount of liquid starting from the minimum level 18, without this entering the tub 3 by the addition of this relatively small amount of liquid.
- the controller 1 1 executes the respective mode according to the program flow.
- the conduit 50 in this embodiment may serve as a feed line 50, which opens into the drainage channel 53 between the outlet 54 and the pump 55.
- the siphon 15 is partially formed by the supply line 50 and partially by the drain channel 53.
- the invention is not limited to the illustrated and described embodiments. LIST OF REFERENCE NUMBERS
