Description

The invention relates to a directional control valve for a household appliance, wherein the directional control valve has an inlet, a first outlet and a second outlet. The invention also relates to a household appliance with such a directional control valve. The household appliance may in particular be a laundry drying device, in particular equipped with a heat pump.

A clothes dryer with a heat pump typically has a heat sink (in particular an evaporator for a refrigerant), which extracts heat from a process air circulating in this dryer and thereby partially condenses the water contained in it. An associated heat exchanger has a lamellar structure on which the lint still contained in the process air separates. These fluff leads to a deterioration of the heat exchange efficiency and subsequent drying performance. The lint is therefore rinsed cyclically with the condensate or condensation produced by condensing of the slats. There are such dryers are known in which the condensate is pumped into a high-level washing and collected there. At the entrance of the rinsing container, a filter is positioned, which filters the lint out of the water. By opening a drain valve on the rinse tank, the water contained therein can bang through a downpipe on the lamellar structure of the washing and thereby clean the lint. The rinsing container is removable, e.g. for emptying and removing and user-side cleaning of the filter. In such a tumble dryer, it is disadvantageous that it is constructed comparatively expensive. Thus, it must be ensured in the tumble dryer that the downpipe must be perpendicular or at least approximately vertical. This also restricts a possibility of positioning the washing container. In addition, such a rinsing direction of the lamellar structure is predetermined from top to bottom, so that in some places permanent residues of lint can form.

The DE 10 2011 087 202 B3 discloses a filter that is used in particular for water-conducting household appliances. The filter comprises a filter housing and a filter element arranged in the filter housing. In this case, the filter housing has an input and an output. The filter element is pivotable about an axis such that the filter element can be flowed through in opposite directions with respect to a flow direction from the inlet to the outlet. Furthermore, a water-conducting household appliance is specified with such a filter. By pivoting the filter element filter residues can be removed.

The EP 1 098 028 B1 discloses a clothes dryer having a dry air blower, a lint filter arranged in a dry air duct, a device for blowing off lint from the lint filter and a device for removing blown lint, characterized in that it comprises means for reducing or closing the cross section of the dry air duct and for producing a Having air jet for blowing off lint with the dry air blower.

The EP 2 422 010 B1 discloses a household laundry drying apparatus comprising at least one filter container, wherein the at least one filter container comprises at least: a chamber with an inlet for condensate to be cleaned, a first outlet and a second outlet and a filter element which is arranged between the inlet and the first outlet and dividing the chamber into an inlet-side first chamber part and a second chamber part, wherein the filter container is alignable such that the inlet is arranged below the filter element and the filter element is arranged below the first outlet and wherein the second outlet opens into the first chamber part, and further wherein particles deposited on the filter element from a liquid forced through the inlet into the chamber are detachable from the filter element and removable through the second outlet upon termination of the pressure by liquid flowing back into the chamber, and further wherein the inlet and second outlet opposite open into the chamber and the first sequence is arranged with respect to the inlet side of the chamber.

The EP 2 516 720 A1 discloses a filter device for filtering a liquid of a domestic appliance, comprising: a valveless filter container having an inlet fluidly connected to a first outlet by at least one filter element and not fluidly connected to a second outlet, a first flow channel communicating with the first Drain is connected and having a shut-off valve, a second flow channel, which is connected to the second outlet and is not shut off for setting a filter position, wherein a first minimum flow area of the first flow and / or the first flow channel is greater than a second minimum flow cross-section of the second drain and / or the second flow channel, so that in a first filter position in which the shut-off valve is opened, the liquid from the inlet through the filter element, the first drain and the first flow channel is pumpable and in a second filter position, in which the shut-off valve blocks, the fluid from the inlet is unfiltered through the second outlet and the second flow channel pumpable.

It is the object of the present invention to at least partially overcome the disadvantages of the prior art and, in particular, to provide a possibility for improved flushing of at least one functional component of a domestic appliance, in particular a lamellar structure of a heat exchanger.

This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims, the following description and the accompanying drawings removable.

The object is accordingly achieved by means of a directional control valve for a household appliance, which has at least: a housing having a first inlet, a second inlet, a first outlet and a second outlet, a switch body movably accommodated in the housing, which switch body has a continuous connecting channel with one first channel opening and a second channel opening, and which connection channel has a cavity, in which cavity a filter extending between the first channel opening and the second channel opening is accommodated. The switch body has at least a first operating position and a second operating position. In the first operating position, a connection between the first inlet and the first outlet is produced by the switch body. A connection between the second inlet and the second outlet of the housing is then interrupted by the switch body. In the second operating position, a connection between the second inlet and the second outlet of the housing is produced by the switch body. A connection through the switch body between the first inlet and the first outlet is interrupted.

This directional control valve has the advantage that it is compact and robust. It is able to produce a pressurized connection between pairs of functional components of the household appliance in a structurally simple manner. In particular, such a pressurized connection between a pump and at least one functional component may optionally be made or separated. For example, a pressurized connection between a pump and optionally a purge container and a purifier may be made. As a result, a cleaning direction and / or a cleaning pressure of the cleaning device can be set variably for improved cleaning performance because it is now possible to dispense with a downpipe. The absence of the downpipe also allows flexible positioning of the washing compartment. In addition, the directional control valve comes with a few, simply constructed components, so that a cost for a production is low.

The household appliance is in particular a water-conducting household appliance. The water-bearing household appliance may be especially a large household appliance. The water-conducting domestic appliance may be, for example, a laundry treatment appliance, in particular laundry drying appliance, a dishwasher, a cooking appliance, in particular steamer, or a refrigerator. The clothes drying machine may e.g. an independent tumble dryer or a washing / drying combination device (washer-dryer).

The directional control valve is in particular a liquid valve for conducting liquid, in particular water.

The channel opening may also be referred to as a control opening. The cavity may also be referred to as a chamber or filter chamber.

The fact that the at least one filter extends in the cavity between the first channel opening and the second channel opening means, in particular, that liquid flowing through the cavity flows through the at least one filter. Specifically, no tributary flows past the at least one filter between the first channel opening and the second channel opening. This ensures that lint or the like, which flow into one of the channel openings with the liquid, do not escape from the other channel opening unfiltered, but are collected by the filter.

The above directional control valve may be regarded in particular as a 4/2-way valve with four (outer) ports and two switching positions. However, the invention is not so limited and, for example, there may be more than two pairs with a respective inlet and outlet, e.g. a third inlet and a third outlet, etc. Also, in the presence of n pairs of inlet and outlet, the directional control valve n may assume suitable switching positions.

The switch body may for example be moved or switched by means of an electric motor or by means of an actuator.

It is a preferred embodiment that in the first operating position of the first inlet to the first channel opening and the first outlet are connected to the second channel opening and in the second operating position of the second outlet to the first channel opening and the second inlet to the second channel opening are connected , Thus, liquid flows through the inlets and out through the outlets, the direction of flow is reversed through the connection channel when switching the switching positions to. As a result, lint, etc., which have accumulated in one operating position on one side of the at least one filter, can be released again in the other operating position. This configuration thus enables at least partial lint cleaning when the filter is used. Specifically, having an inlet or outlet connected to a channel opening means that the inlet or outlet and the channel opening form a common opening for the cavity. The inlet or the outlet and the channel opening are in particular directly (possibly only spaced apart from each other by the gap between housing and switch body) and are therefore not separated from each other by the cavity, but form a common opening for the cavity. The inlet or the outlet and the channel opening need not be completely congruent, but should at least have congruent partial areas.

It is still a preferred embodiment that the housing is a hollow cylindrical housing and the switch body is a rotatably arranged in the hollow cylindrical housing, hollow cylindrical body. Thereby, a switching between the switching positions can be achieved by a rotation of the switch body in the housing.

This makes it possible to provide a particularly compact and easy to manufacture way valve. The housing and the switch body are in particular formed as a concentrically arranged, about a common longitudinal axis against each other rotatable hollow cylinder. The inlets, the outlets and the channel openings are formed in particular as openings, holes or openings. The housing and the switch body may also be referred to as (in particular stationary) "outer cylinder" or (in particular rotatable) "inner cylinder". The directional control valve may also be referred to as a "rotary filter".

It is a further preferred embodiment that the inlets and the outlets of the housing are introduced in a lateral surface of the housing, the channel openings are introduced in a lateral surface of the switch body and the first inlet to the first outlet and the second inlet to the second outlet a same Have angular offset as the first channel opening to the second channel opening. As a result, an at least partial coverage of some inlets and outlets on the one hand and the channel openings on the other hand is achieved in a particularly simple manner.

It is still a further preferred embodiment that the channel openings are arranged separated by the cavity opposite or are arranged at opposite regions or positions of the cavity. As a result, a particularly low flow resistance can be achieved, since the liquid flow can then flow in a structurally simple manner at least approximately rectilinearly through the connecting channel.

It is also a preferred embodiment that the first inlet, the second outlet and the first channel opening are located at the same longitudinal position and the second inlet, the first outlet and the second channel opening are in the same longitudinal position. Thereby, the first channel opening can be selectively connected to the first inlet or to the second outlet and the second channel opening optionally to the second inlet or to the first outlet by simple rotation.

In particular, the first inlet, the second outlet and the first channel opening may have a same basic shape. Also, the second inlet, the first outlet and the second channel opening may have a same basic shape.

It is also a preferred embodiment that the first inlet and the second inlet are connected to a common supply line. As a result, liquid flowing in the supply line can be conducted in a particularly simple manner into one of two flow branches, which are connected to the first outlet or to the second outlet. In particular, in this embodiment, the directional control valve is a two-way valve.

It is also a preferred embodiment that the channel openings are surrounded by a respective seal against the housing. As a result, a leakage current through a gap between the housing and the switch body is prevented. In addition, contaminants that get into the gap, do not lead to a blocking of the rotation. Rather, the seals can slide over contaminants while still providing a sufficient seal. This embodiment is particularly advantageous if a gap distance between the housing and the switch body to reduce a possibility of setting lint, soils, etc. in the gap is comparatively large, e.g. is three to five millimeters.

The seal may for example be in the form of at least one elastic sealing rib or be formed. The sealing rib is preferably perpendicular between the housing and the switch body, in the presence of a cylindrical switch body preferably perpendicular to the lateral surface.

It is generally preferred to increase the robustness against contamination development that the gap width and the gap distance between the housing and the switch body is about three to five millimeters.

It is a preferred embodiment for improving the cleaning of the filter that within the cavity, at least one body which does not fit through the channel openings is loosely inserted or enclosed. As a result of the liquid flow, the at least one body is swirled about, mechanically removing impurities, e.g. Lint, from the surface of the filter. It is a preferred development that the at least one body made of plastic, which is particularly inexpensive and does not damage the cavity. The at least one body is preferably angular, e.g. pyramidal or cube-shaped.

It is a preferred embodiment for reliably preventing permanent clogging of the at least one filter that the filter can be removed. For example, a cover of the directional control valve may be removable. The cavity of the switch body may for example have at least one guide rail for receiving the filter. The filter is for use in the cavity e.g. in the at least one guide rail inserted. In particular, the filter may be removed and cleaned by an end user or customer. This also makes it possible to ensure a minimum effectiveness of the filter performance.

The object is also achieved by a household appliance, comprising at least one inventive directional control valve as described above. The household appliance may be designed analogously to the directional control valve and has the same advantages.

It is a preferred embodiment that the first inlet and the second inlet of the directional control valve are connected to a pump of the household appliance, the first outlet is connected to a first liquid-conducting functional part of the household appliance and the second outlet is connected to a second liquid-conducting functional part of the household appliance. It is thus possible to pump water optionally to at least two liquid-conducting functional parts. In particular, if the two operating positions are associated with a reversal of the flow direction in the connecting channel, the directional control valve may serve as one of the functional parts in particular as a filter device and take on line to the other of the functional parts of the filter dissolved lint and other retained impurities ,

It is still a preferred embodiment that the household appliance is a laundry drying device, the first functional part is a condensate storage and the second functional part is a cleaning device. Thus, liquid can be pumped into a, in particular removable, condensate storage, for example, so that the liquid can be drained from it by a user. The liquid can alternatively be pumped to at least one cleaning device, so that it cleans at least one functional part of the tumble dryer. A cleaning device may, for example, be set up and arranged for cleaning, in particular rinsing, of a process air filter. The process air filter may in particular be introduced into a process air duct of the laundry drying apparatus and retain lint, etc., from the process air there. Another cleaning device may, for example, be set up and arranged for cleaning, in particular rinsing, of a heat exchanger, in particular a heat exchanger of a heat pump laundry drying device, in particular of its cooling fins.

It is a preferred development that the two operating positions are connected to a reversal of the flow direction in the connecting channel. Thus, the directional control valve, in particular in a conduit of condensed water from the pump to the cleaning device mainly serve as a filter, while the directional valve entrains in particular in a line of condensed water from the pump to the condensate storage of the filter dissolved lint and other retained impurities.

It is still a preferred embodiment that the pump is adapted to pump liquid from a condensate collection tray. This helps to prevent overflow of the condensate collection tray. The evacuated condensed water may be directed to a purifier, if necessary, otherwise, e.g. in the condensate storage tank.

The condensed water may be pumped into a drain or drain of the household appliance in addition or as an alternative to being able to pump it into the condensate storage. Alternatively or in addition to condensate, fresh water or a mixture thereof may also be pumped.

The above-described characteristics, features, and advantages of this invention, as well as the manner in which they are achieved, will become clearer and more clearly understood in connection with the following schematic description of an embodiment, taken in conjunction with the figures of the accompanying drawings is explained. In this case, the same or equivalent elements may be provided with the same reference numerals for clarity. Show it:

1 a directional control valve with connected pump in a view obliquely from behind;

2 a cross section through the directional control valve 1 in a first operating position, in a view obliquely from the front;

3 a cross section through the directional control valve in its first operating position in a front view;

4 a cross section through the directional control valve in a second operating position, in a view obliquely from the front; and

5 a cross section through the directional control valve in its second operating position, in a front view.

1 shows diagonally from behind a 4/2-way valve 1 with connected pump P of a household appliance in the form of a heat pump dryer W. The directional control valve 1 has a fixed housing 2 with a first inlet 3 , a second inlet 4 , a first outlet 5 (please refer 2 ) and a second outlet 6 on. The housing 2 has a horizontal, hollow cylindrical basic shape. The inlets 3 . 4 and the outlets 5 . 6 of the housing 2 are in a lateral surface 7 of the housing 2 brought in.

The first inlet 3 and the second inlet 4 are connected to a common, external supply line 8th connected. The supply line 8th is connected on the one hand via a connecting line V to a pressure-side pump outlet A of the pump P and divides or branches on the other hand to the inlets 3 and 4 , When the pump P is running, so lies at both inlets 3 and 4 a pressure of a pumped by the pump P liquid: here: water, on. The pump P is connected via its suction-side pump inlet E, which is designed here as an intake, with a condensate collection tray K and thus adapted to typically pollute, for example, lint, condensed water from the condensate collection tray K pump. The first outlet 5 is via a first outlet line 9 connected to a condensate storage B, and the second outlet 6 is via a second outlet line 10 connected to a cleaning device R of the heat pump dryer W.

2 shows in a view obliquely from the front a cross section through the directional control valve 1 in a first operating position, which is referred to below without restriction of the general public as "pumpdown". 3 shows a cross section through the directional control valve 1 in the pumpdown position as a frontal view.

In the hollow cylindrical housing 2 ("Outer cylinder") is a switch body 11 housed in the form of a hollow cylinder ("inner cylinder"), which has a cylindrical cavity 12 surrounds. The housing 2 and the switch body 11 are arranged concentrically to each other and separated by an annular gap d. The annular gap d is here a narrow annular gap of less than 3 mm height. The switch body 11 is inside the case 2 rotatably arranged, for example by means of an actuator or an electric motor, etc. By the rotation of the switch body 11 between the first operating position shown and one in the 4 and 5 shown switchable second position.

In a coat-side wall 13 of the switch body 11 are on opposite sides a first channel opening 14 (please refer 3 ) or a second channel opening 15 housed, which can also be referred to as "control openings". The canal openings 14 and 15 form together with the cavity 12 a continuous connection channel 12 , 14,15, which in the Abpumpstellung the first inlet 3 with the first outlet 5 combines. To do this, cover the first inlet 3 and the first channel opening 14 such that they form a continuous opening; Also cover the first outlet 5 and the second channel opening 15 so that they form a continuous opening. The first inlet 3 and the first outlet 5 are therefore also at opposite positions in a jacket-shaped region of the housing 2 brought in. In the Abpumpstellung the pump P is therefore the pressure side via the directional control valve 1 hydraulically connected to the condensate storage B. The second inlet 4 and the second outlet 6 On the other hand, they are not connected or interrupted against each other.

Inside the cavity 12 is a filter 16 (Eg a single-layer or multi-layer sieve) housed, which is located between the first channel opening 14 and the second channel opening 15 extends. This is the filter 16 transverse to a mental connecting line between the first channel opening 14 and the second channel opening 15 , The filter 16 thus divides the cavity into a first subspace 12a and in a second subspace 12b on, with the first channel opening 14 in the first subspace 12a opens and the second channel opening 15 in the second subspace 12b opens. The two subspaces 12a and 12b are equal here, because the filter 16 the cylindrical cavity 12 along its longitudinal extent at its greatest width divides.

The switch body 11 has on its inner side in the region of its greatest width opposite, extending along the longitudinal extent guide rails 17 on. The rectangular filter 16 is in the guide rails 17 plugged in and removed again by pulling out. The filter is thus out of the directional control valve 1 removable, eg for a cleaning of the filter 16 and / or for introducing a replacement filter. A corresponding end-side cover (not shown) of the directional control valve 1 is then removable accordingly, for example, by an end user.

Within the second subspace 12b of the cavity 12 There are loose several plastic pyramids 18 which are not through the channel openings 14 . 15 fit. Its shape becomes a blockage of the channel openings 14 . 15 avoided. The plastic pyramids 18 serve on their subspace 12b facing surface of the filter 16 deposited impurities mechanically from the filter 16 to solve.

4 shows in a view obliquely from the front a cross section through the directional control valve 1 in a second operating position, which is also referred to below as "filter position" without restriction of generality. 5 shows a frontal view of a cross section through the directional control valve 1 in its second operating position. For transfer from the first Abpumpstellung in the second filter position is the actuator 11 Turned about 20 ° clockwise. This is by means of the connection channel 12 . 14 . 15 now a connection between the second inlet 4 and the second outlet 6 has been produced, which is also on the lateral surface 7 of the housing 2 are opposite. In the filter position, the pump P is on the pressure side via the directional control valve 1 connected to the cleaning device R. The first inlet 3 and the first outlet 5 On the other hand, they are no longer hydraulically connected to each other or are interrupted against each other.

More precisely, the second outlet is now 6 with the first channel opening 14 connected by these two openings adjacent cover and not through the cavity 12 are separated from each other. The second inlet 4 is on the other hand with the second channel opening 15 immediately (and not just over the cavity 12 ) connected. In other words, now form the second outlet 6 and the first channel opening 14 a common opening for the cavity 12 , and the second inlet 4 and the second channel opening 15 form another common opening for the cavity 12 , As a result, the flow direction in the filter position is reversed compared to the pumping position.

During operation of the heat pump dryer W, for example, the directional valve 1 First, the pumping position according to the 2 and 3 taking. At the beginning of a drying process, condensate water is then pumped out of the condensed water collecting trough K by operation of the pump P, through the first inlet 3 and the first channel opening 14 in the cavity 12 pumped in, continue through the filter 16 pressed, then through the second channel opening 15 and the first outlet 5 from the cavity 12 pressed and following through the first outlet line 9 directed to the condensate storage B. It may like a few lint or similar. on the filter 16 be withheld.

In the further course of the drying process, the cleaning device R is repeatedly actuated. These are the directional control valve 1 spent in the filter position and the pump P is turned on. The pump P now pumps condensed water from the condensate collection tray K through the second inlet 4 and the second channel opening 15 in the cavity 12 , continue through the filter 16 , then through the first channel opening 14 and the first outlet 5 from the cavity 12 out and next through the second outlet pipe 10 to the cleaning device R. It may be due to the reversal of the flow direction previously during the operation of the pump P in the Abpumpstellung of the filter 16 retained a few lint. However, this is not critical due to the relatively low accumulation of lint, especially if much water is pumped in the filter position. The cleaning device R is thus pressurized, filtered water available. As a result, the cleaning device R can easily dispense the water from any direction onto the functional component to be cleaned, eg from above, from below and / or from the side, eg to a process air filter or to a heat exchanger. The cleaning device R may have corresponding nozzles.

Be during the drying process several cleaning operations with the directional control valve 2 performed in the filter position, comparatively many lint on the filter 16 deposited. After the drying process or - especially if the filter is clogged 16 - Even during the drying process, the directional control valve 1 for cleaning the filter 16 returned to the pumping position and turned on the pump P. As a result, due to the renewed reversal of the flow direction in the cavity 12 during the at least one cleaning operation of the filter 16 retained impurities, such as lint, from the filter 16 rinsed and in the condensate storage B (alternatively, for example, in a drain) passed. This is a replacement of the lint by the swirling plastic pyramids 18 supported. The detachment of the lint is through the plastic pyramids 18 supported. The filter 16 will be cleaned. The condensate storage B with its highly polluted, in particular mixed with fluff, water may for example be removed from the heat pump dryer W. and emptied and possibly cleaned, eg by an end customer.

In particular, if the condensate collection tray K is comparatively large volume, may be dispensed with separate Abpumpvorgänge during the drying process, in particular between cleaning operations.

Of course, the present invention is not limited to the embodiment shown.

In addition or as an alternative to condensation, the pump may also pump fresh water.

Also may be dispensed with an initial pumping out of the condensate.

The plastic body, in particular plastic pyramids, may in principle be located in the first subspace of the cavity and / or in the second subspace of the cavity.

Generally, "on", "an", etc. may be taken to mean a singular or a plurality, in particular in the sense of "at least one" or "one or more" etc., unless this is explicitly excluded, e.g. by the expression "exactly one", etc.

Also, a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
