Definitions
- Dishwasher with a water flow control device Dishwasher with a water flow control device
- the present invention relates to a dishwasher with a water flow control device comprising a movably mounted closure element which is alternately movable to one of a plurality of control positions so as to control a flow of water from at least one water inlet to at least one water outlet, and a sensor device which detects an intake the control positions detected by the closure element has.
- Dishwashers each with a water flow control device are from the
- the water switch has a movably mounted closure element, which is movable by a drive in each one of a plurality of provided control positions. In each of the control positions, one of the water outlets is connected to the water inlet.
- a selected spray element for example via one of several rotatable spray arms
- a spray pressure in the respective controlled, supplied with rinsing liquid spray element and thus an improvement of the washing result can be achieved.
- the closure element of the water distributor is coupled to a cam, which actuates a pressure switch upon reaching a designated control position.
- the control device detects the reaching of a control position and then switches off the drive of the closure element.
- Such a water separator with a cam disc and a pressure switch for a dishwasher has a comparatively complicated mechanical structure. Dirt or wear of the mechanical components may possibly lead to malfunction of the water distributor, which can only be remedied by a complex repair.
- the object of the present invention is to increase the reliability of a dishwasher, in particular household dishwasher, with a water flow control device.
- the object is achieved in a dishwasher, in particular domestic dishwasher, of the type mentioned above in that the sensor device comprises a permanent magnet arrangement and a magnetic field detecting sensor.
- the permanent magnet arrangement and the magnetic field detecting sensor are arranged such that a movement of the closure element to a relative movement between the permanent magnet arrangement and magnetic field detecting sensor takes place.
- the magnetic field acting on the magnetic field-detecting sensor changes as a function of the position of the closure element. This makes it possible to contact one of the control positions by the closure element without contact to capture. Malfunction of the water switch, for example, due to mechanical wear and / or contamination can be effectively avoided.
- the permanent magnet arrangement can be arranged in particular directly on the closure element, so that a coupled movement of closure element and permanent magnet arrangement is ensured without additional components.
- the invention causes a simplification of the mechanical structure of the water flow control device, as can be completely dispensed with the previously required cam and a pressure switch controlled by this. This results, in addition to the already mentioned improvement of
- the sensor device of the dishwasher according to the invention in particular household dishwasher, further reduces the mechanical load on the drive of the closure element, since the mechanical friction between the cam and pressure switch is eliminated. This increases the reliability of the drive. Likewise, in many cases, a less efficient drive can be used. Due to the non-contact sensor principle, it is also possible to reduce the number of points which must be equipped with a continuous lubrication device or with periodically serviceable lubrication.
- Permanent magnet arrangement at least one permanent magnet component fastened to the closure element.
- the permanent magnet component may comprise one or more permanent magnets.
- the attachment can for example by gluing respectively. In this way, the water flow control device according to the invention is easy to manufacture and reliable.
- the closure element may comprise at least one portion of a hard magnetic material, wherein the permanent magnet arrangement at least one
- Permanent magnet formed by permanently magnetizing a portion of the portion of the hard magnetic material.
- Hard magnetic materials have a wide hysteresis loop with high coercivity. If such substances are exposed to a sufficiently strong magnetic field, they have a permanently remaining independent magnetic field after removal of the external magnetic field. This makes it possible, in particular homogeneous form the hard magnetic portion of the closure element in material terms and then selectively magnetize individual parts of the section by an external magnetic field, so as to form permanent magnets. In this way, the permanent magnet assembly can be completely integrated into the structure of the closure element.
- the closure element including the permanent magnet assembly can be made so very compact.
- the hard magnetic section comprises only a small part of the closure element.
- the closure element may also consist entirely of hard magnetic material.
- closure elements can be readily adapted for use in different water flow control devices.
- the hard magnetic material may be a carrier material made of plastic with hard magnetic particles embedded therein. From such hard magnetic materials can be in a simple manner by means of known primary molding processes such as extrusion, injection molding or compression molding be formed almost arbitrarily shaped hard magnetic sections. In this way, the closure element as a whole can be easily manufactured.
- the closure element has a portion of a non-magnetic material, which is formed integrally with the portion of the hard magnetic material.
- a non-magnetic material By one-piece construction of the various sections is meant, in particular, that they consist of a single body made using only a molded body.
- the closure element may in particular be or comprise a multi-component injection-molded part. Multi-component injection molding allow the one-piece design of
- molded parts wherein different sections may consist of different materials.
- one-piece molded parts made of different materials can also be produced by means of compression molding or in a coextrusion, extrusion coating, laminating or laminating process.
- a closure element can be manufactured with several sections, wherein the material of each section can be optimized specifically. Nevertheless arise between the different sections of the closure element no joints by subsequent connection of independently formed components, so that potential weaknesses are avoided in the structural design of the closure element.
- the non-magnetic material can essentially correspond to the carrier material.
- a particularly good strength in the transition region of the various sections can be achieved by means of this single-material formation of the respective closure element; on the other hand, the material recycling of disused closure elements is simplified.
- the hard magnetic particles may include hard ferrites and / or rare earths, such as neodymium.
- the materials mentioned allow the generation of comparatively strong permanent magnetic fields. This facilitates the detection of the same, which also the
- the plastic may be a thermoplastic material.
- Thermoplastics allow a high proportion of magnetic particles without the stability of the section produced thereby all too reduced.
- Suitable plastics are in particular polypropylene, polyphenylsulfide, Polyetherechterketon or mixtures thereof.
- the closure element is in particular formed in one piece. In this way, joints are avoided, which benefits the stability of the closure element. In addition, the production of the closure element simplifies.
- the senor may be a magnetoresistive sensor, a Hall sensor or a reed switch.
- the sensor types mentioned in contrast to coil sensors, also allow the detection of the magnetic field of the permanent magnet arrangement when it is stationary with respect to the sensor.
- Reed switches have iron metal lips, which attract with an applied magnetic field and thus establish an electrical contact. Reed switches are very simple and reliable. In addition, they are able to switch relatively large currents, so that signal amplifiers can be dispensed with as a rule.
- Hall sensors are based on the effect that in a magnetic field moving charge carriers are deflected. They provide a signal, in particular voltage signal, which is proportional to the applied magnetic field. In this way it is possible to detect a maximum or a minimum of the magnetic field generated by the permanent magnet arrangement, so as to move the closure element particularly accurately into a provided control position.
- Magnetoresistive sensors rely on the change in electrical resistance in thin ferromagnetic layers when a magnetic field is applied. Magnetoresistive sensors are particularly sensitive, so that the permanent magnet arrangement only has to generate small magnetic fields and therefore can be constructed in a simple and compact manner. In addition, the distance between the sensor and Permanent magnet arrangement can be chosen comparatively large, which provides constructive advantages in many cases.
- the closure element can be rotationally movable about an axis compared to water points where the closure element is translationally movable, so much more compact dimensions can be achieved.
- the permanent magnet arrangement can be arranged, in particular, on a section of the closure element lying outside on the axis.
- the closure element can in particular be designed as a closure plate with at least one axially permeable one
- the axially through ström bare water passage allows depending on the position of the closure element, a flow of water from one or more water inlets to one or more water outlets.
- the water passage may be, for example, an opening or recess in a flat and circular shutter disc.
- the water flow in this case runs in the region of the water passage substantially parallel to the axis of rotation of the closure disk.
- Shutter plates with an axially through ble ble water passage are comparatively easy to produce and cause a compact design of the water gate total, especially if the inflow of water and the outflow of water also take place substantially in the axial direction.
- the closure element may alternatively be formed as a cup wheel with at least one radially through-flow water passage.
- a design of the closure element is particularly advantageous when water inlets and water outlets are radially aligned. In this way, a particularly flat design of the water switch can be realized.
- Water control device preferably designed as a water diverter, which has a plurality of water outlets, wherein for at least one water outlet, preferably for each water outlet, a switching position is provided in which the respective water outlet is individually connected to the water inlet.
- a water switch makes it possible to direct water from a single source to one of several consumers of water of the dishwasher.
- water originating from a single pump can be directed selectively or selectively to a spray element of a plurality of spray elements in order to spray water in a dish containing dishes for the purpose of cleaning.
- a particularly strong spray in particular selectively or individually.
- the water control device may optionally be designed as a water distributor, which has a plurality of water outlets, wherein a switching position is provided, in which a plurality of water outlets are connected to the water inlet. If such a water diverter for controlling the water flow of a spray system of
- the water flow can be better adapted to the particular situation.
- a particularly uniform loading of the Spül matterserinnenraums can be realized with water. This can, for example, bring about an improvement in the rinse-off result in a rinse cycle.
- the permanent magnet arrangement may in particular have a coding which allows a distinction of the switching positions. Coding in the present sense makes it possible to determine from the signals of the magnetic field-detecting sensor not only whether the closure element is located in one of the intended control positions, but also in which individual or specific control positions it is currently located.
- Such coding can be realized by assigning to each of the possible control positions a specific portion of the permanent magnet assembly, each portion generating a magnetic field according to an individual pattern.
- Such coding makes it possible to bring the closure element by means of the drive in a certain, desired control position, even if at the beginning of the movement, the starting position of the closure element is unknown, which can occur, for example, after a malfunction or after a power failure.
- the coding can be formed by different dimensions of the permanent magnets in a provided relative movement direction and / or by different spaces between the permanent magnets in a planned direction of relative movement.
- the individual switching position can be determined from the shape of the signal of the magnetic field detecting sensor, wherein the absolute amplitude of the magnetic field or the sensor signal is insignificant.
- the identification of the respective assumed switching position can be determined with great certainty even if the magnetic field of the permanent magnet arrangement has decreased overall, for example due to aging. In this way, a permanently lasting functional reliability of the water flow control device can be ensured.
- the invention enables a positionally correct, cost-effective position detection (synchronization) of the closure element of a water flow control device.
- a water flow control device of a dishwasher serves to close and open hydraulic channels and thereby to a reduction of the rinsing fluid in circulation. This opening and closing takes place in the case of water-flow control devices, such as, for example, water softeners based on disk solutions, through the so-called closure disk.
- the invention can also be applied to alternative closure elements, such as cup wheels, rotary valves, trombone valves.
- the control of the closure elements two similar approaches are known from the prior art.
- an additional cam is arranged on the shaft which drives the shutter disc of the water switch, which upon reaching a certain desired position of the water switch an additional sensor, such as a pressure switch, either opens or closes.
- an additional sensor such as a pressure switch
- the controller recognizes the achievement of this position and then switches off the drive of the disc (comprising, for example, a synchronous motor). Due to the additional components pressure switch and cam, this solution may be too expensive in practice.
- the second approach is also based on an additional cam which is e.g. via a lever mechanism opens or closes an additional circuit.
- the additional cam and the lever components (lever, spring, bearings) of the lever mechanism this solution may also be too expensive in practice.
- the present invention provides an advantageous
- Embodiment a water-immersed closure element in particular from a magnetizable plastic before.
- the position detection of the disc can be carried out directly via a low-cost Hall sensor without additional components having to be provided and mounted.
- the advantageous embodiment of the invention provides a magnetization in particular of the collar of the closure element, since this has the largest radius and thus a maximum of accuracy can be achieved in positioning.
- the closure disk preferably has magnetized segments of different lengths, so that synchronization of the water separator is ensured even in the event of a power failure.
- the control can ascertain, in particular by time-measuring the signal, in which concrete position the closure element is located. In particular, the times can be evaluated in which the signal is above or below a certain threshold.
- the advantages of the underlying design lie in a reduced complexity of the system (at least one component, namely the cam disc, less) in reduced Costs due to lower number of components, in reduced cost due to a saving in assembly of the additional components, in a lower load of the drive motor, since no mechanical friction between the cam and switch occurs, resulting in improved quality or the use of a lower power motor, at a cost allows to avoid lubrication points on moving components and in an increased flexibility in terms of the intended control positions, as the closure element can be easily recoded.

- Figure 3 is a partially sectioned view of the water flow control device when viewed from the side.
- Figure 1 shows a schematic representation of an inventive
- Dishwasher 1 in particular domestic dishwasher, wherein only the components required for understanding the invention are shown and explained.
- the dishwasher 1 has a washing container 2, to be cleaned in the Dishes can be introduced.
- water W is used, which may be phase-displaced with cleaning substances or auxiliary substances, such as, for example, rinse aid, in the course of a washing program selected by an operator.
- a pump 4 is connected to the bottom pan 3.
- the pump 4 makes it possible, as symbolized by the solid straight arrows, to pump water W originating from the floor pan 3 to a water flow control device 5.
- the water flow control device 5 is designed as a water diverter 5, which makes it possible to spray the water W either via a lower spray arm 6 or an upper spray arm 7 in the washing or pumping out via a sewage connection 8 to the outside, which is shown by dashed arrows.
- the water switch 5 is an unillustrated drive, for example, associated with an electric motor, which, like the pump 4 is controlled by a control device of the dishwasher 1 in response to a selected wash program.
- a control device of the dishwasher 1 in response to a selected wash program.
- the connection from the pump 4 to the wastewater connection 8 is usually closed.
- the spray arms 6 and 7 are arranged rotatably in the washing container 2. It goes without saying that fixed spray elements could alternatively or additionally be provided.
- the water diverter 5 is actuated so that the water W is pumped out via the waste water connection 8.
- the connection from the pump 4 to the spray arms 6, 7 is interrupted.
- FIG. 2 shows a schematic sectional view of the water diverter 5 of FIG. 1.
- the water diverter 5 has a housing 9, which is made of plastic, for example is.
- a closure element 10 is arranged, which is connected to an axle 11 and is rotatably mounted together with this.
- the axis 1 1 is connected to a controllable drive, not shown, so that the closure element 10 is movable in a direction indicated by the double arrow BR intended movement direction.
- the closure disk 10 has a water passage 12. This is arranged in the radial direction so that, when the closure element 10 is in a first control position shown in FIG. 2, it corresponds to a first water outlet 13.
- the water outlet 13 is formed on the housing 9 of the water distributor 5 and connected, for example, with a line to the lower spray arm 6 shown in FIG.
- a second water outlet 14 is formed, which is connected to the upper spray arm 7 shown in Figure 1.
- the closure element 10 is movable by a rotation in a second control position, wherein the water passage 12 corresponds to the second water outlet 14.
- a third water outlet 15 is provided, which is connected, for example, via a hose to the wastewater connection 8 shown in FIG. In this case, the closure element 10 can be brought into a third control position, in which the third water outlet 15 corresponds to the water passage 12.
- the closure disc 10 here in the embodiment exactly has a water passage 12, when taking one of the control positions, a water flow from the bottom of the shutter disk 10 to exactly one of the water outlets 13, 14, 15, i. selectively possible. It is essential for the function of the dishwasher that the respective intended control position is taken exactly. If, for example, the first control position shown in FIG. 2 were only followed in an imprecise manner, so that the water passage 12 and water outlet 13 would only partially overlap, the flow of water into the washing container 2 (FIG. 1) would be reduced, which would lead to an unsatisfactory wash result.
- a sensor device 16, 17 is provided.
- This sensor device 16, 17 comprises a permanent magnet arrangement 16 and a magnetic field detecting sensor 17. During the Magnetic field detecting sensor 17 is attached to the housing 9, which rotates
- the permanent magnet assembly 16 together with the shutter disk 10 about the central axis 1 1.
- the permanent magnet assembly 16 includes a first position magnet 18 which is in the detection range of the sensor 17 when taking the first switching position. Further position magnets 19 and 20 are arranged so that they take on the second switching position or when taking the third
- coding magnets 21, 22 and 23 are provided which differ from the position magnets 18, 19, 20 in that they have a greater extent in the intended direction of movement BR.
- the mode of operation of the water diverter 5 is now the following: In the initial situation shown in FIG. 2, the closure element is in the first switching position, so that a water flow to the lower spray arm 6 (FIG. 1) is established. If, for example, the rinsing program provides that now the upper spray arm 7 (FIG. 1) is to be selectively or specifically supplied with water, then the water is sprayed through
- Control device of the dishwasher the drive of the water switch turned on, so that the closure element 10 rotates.
- counterclockwise rotation makes sense, but is not required.
- the position magnet 18 When the closure element 10 is rotated counterclockwise, the position magnet 18 initially comes out of the detection range of the sensor 17. This reduces the detected magnetic field until the encoder magnet 21 reaches the detection range of the sensor 17. From the time profile of the signal from the sensor 17, the control device of the dishwasher detects that it is the magnetic field of the coding magnet 21 assigned to the first position magnet 18. The shutter disk 10 is therefore further driven, so that the encoder 22 is detected by the sensor 17 at a later time. Since it is deposited in the control device that exactly two coding magnets 21 and 22 are arranged between the position magnet 18 and the position magnet 19, the drive of the shutter disc 10 continues to be operated by the control device until the magnetic field of the position magnet 19 is detected.
- the shutter member 10 has reached its second control position, so that the drive can be turned off.
- the second control position corresponds to the Position of the water passage 12 with the position of the water outlet 14, so that now the upper spray arm 7 ( Figure 1) can be acted upon with water.
- the presence of the Kodiermagnete 21 and 22 is not required, since the position of the closure element 10 was known at the beginning of the switching. However, if the position of the closure disk 10, for example after a power failure, is unknown, it can be determined by means of the Kodiermagnete 21, 22, 23, which of the position magnets 18, 19, 20 by rotation of the closure element 10 in the detection range of the sensor 17th was brought. The decision is based on the fact that the first position magnet 18 and its associated coding magnets 21 in
- Direction of movement BR i. Generally speaking, viewed in the circumferential direction a small distance, the second position magnet 19 and the Kodiermagnete 22 a middle distance and the third position magnet 20 and the Kodiermagnete 23 have a large distance from each other. These distances can be detected at a known rotational speed from the time course of the signal of the sensor 17. In this way, even after a malfunction, the closure element 10 can be brought into the selected control position.
- the closure element 10 is preferably an integrally formed multicomponent injection-molded part made of plastic.
- One component of the closure element 10 forms an outer, annular portion 24.
- This outer portion 24 consists of a hard magnetic material, which is a carrier material made of plastic with hard magnetic particles embedded therein.
- another component forms an internal disc-shaped section 25, which consists of a non-magnetic material. Since the closure element 10 as a whole is a multi-component injection-molded part, it has no joint at the transition region from the outer section 24 and from the inner section 25. This results in a particularly stable embodiment of the closure element 10.
- magnets 18-23 are prepared in that the corresponding areas 18-23 have been exposed to the actual physical production of the closure element 10 a strong magnetic field, so that the corresponding areas 18-23 permanently are magnetized.
- the magnets 18-23 are completely integrated into the structure of the closure element 10.
- FIG. 3 shows the water switch 5 of FIG. 2 in a partially sectioned side view.
- the axis 1 1 is guided through the housing 9 through to the outside and connected there to a drive, not shown.
- the closure plate 10 In the left-hand part of the closure element 5, the closure plate 10 is visible. This assumes its first control position, so that the water outlet 14 is closed by the shutter disk 10. In order to achieve a particularly good seal, a seal 26 is provided between the closure disk 10 and the water outlet 14. As a result, a water flow from a water inlet 27 to the water outlet 14 is prevented.
