Description

The water-bearing household appliance of using with device of being used for dispense detergent

Technical field

The present invention relates to a kind of water-bearing household appliance of using, particularly a kind of dish-washing machine, to have and be used for dispense detergent to the home appliances device in the scrubbing space that is defined by wall of dish-washing machine particularly, will to be washed article in order cleaning, it has at least one spraying system in scrubbing space.The device that is used for dispense detergent has the reservoir that is used to hold cleaning agent, its be arranged on the scrubbing space wall that is positioned at approximate vertical or; Be arranged on the reservoir or interior and the flushing element of washing lotion is provided via supply pipe; With first valve that is used to open supply pipe.Be regarded as therein wall a part be the machine door, it can be embodied as the form that is hinged or becomes drawer.Usually be at the free-ended nozzle of supply pipe as what wash element.Washing lotion is to be used to clean the water that will be washed article, with and after entering dish-washing machine, pass through spraying system by the circulating pump pumping.

Background technology

Know that from DE20311432U1 a kind of dish-washing machine has the described device that is the allocation units form, be used for adding cleaning agent, the liquid feed arrangement wherein is provided in allocation units, be used for washing out cleaning agent from allocation units to washing lotion.In order to wash out cleaning agent from allocation units, the part liquid of circulation washing lotion is flowed through and is sent to allocation units by valve and tube-carrier.In case cleaning agent is assigned with, pipe and valve just do not have further function, begin up to another program.

Summary of the invention

The objective of the invention is openly to have the dish-washing machine of the device that is used for dispense detergent, wherein, in order to ensure the reliability of flushing, when during washing procedure, all pipes that are supplied washing lotion can keep constantly using as much as possible.

First valve by imbody in dish-washing machine of the present invention is realized described purpose, and first valve is used for starting selectively flushing element and/or spraying system.For example, injection component can be nozzle or the system that comprises a plurality of nozzles.Both can with fixing or movably mode be arranged in scrubbing space.So, the washing lotion of leaving injection component and spraying system is used for cleaning and will be washed article, is used for washing out cleaning agent from the cleaning agent distributor and leave the washing lotion of washing element.

Unlike the prior art, being based on the element that is provided for washing out from container cleaning agent according to dish-washing machine of the present invention can be used whole washing procedure process.Thereby what avoid is that washing lotion is retained in for a long time in the pipe and can forms sediment.After washing procedure begins, be supplied to the washing lotion of detergent dispenser can begin to be sent to distributor via first valve.Here, it runs into cleaning agent, dissolves it and is sent to scrubbing space.After finishing flushing, washing lotion can be walked around distributor and be sent to additional injection component by conversion first valve to shunt valve then.For example, but additional injection component spray by all the other spraying systems and do not have or not have the fully zone of the scrubbing space of arrival in the concentrated area then.Except that the high reliability of container flushing, additionally provide the advantage that can be independent of the spraying system dispense detergent according to apparatus of the present invention by the flushing element.As a result, be disposed in will be washed article and will not stop flushing process before the distributor.In addition, device according to the present invention will allow the amount of part washing agent to be assigned with in different program times by correspondingly operating valve.This valve also allows side by side to be sent to such as washing lotion the control mode of cleaning agent distributor and shunt valve., depend on demand here, controllable flow is gone into the washing lotion amount of cleaning agent distributor or shunt valve.

Injection component can be the part of spraying system.It is usually placed in three planes of scrubbing space, for example with the form of rotating spray arm or static nozzle system.Then, shunt valve for example will stop at the additional nozzle place of spraying system.

Additional injection component also can be supported from container flushing cleaning agent.For this purpose, can in container, other opening be set towards the scrubbing space direction, especially it can be closed this other opening before dispense detergent is to the scrubbing space.Then, during assigning process, the washing lotion of additional injection component also can arrive container by this opening.Then, this first valve will be with so a kind of mode switch, and it is sent to washing lotion flushing element and injection component during flushing process.Can wash out cleaning agent fully from container as a result, even in shorter time.

Therefore, by additional injection component, can support to rinse out cleaning agent from container from scrubbing space.For this purpose, it is favourable pointing to towards the direction of scrubbing space when having at least for the opening of container.The more washing lotion of time per unit will can arrive the cleaning agent that is used to wash by this way, the result, and flushing process will be accelerated and strengthen.In the advantageous embodiment of apparatus of the present invention, the part of container at least is installed movably, for example wall or bottom.In order to wash out the purpose of cleaning agent, movable part moves to distribution locations from original position.In situ, close, contact with washing lotion so that prevent cleaning agent towards the container of scrubbing space direction.In distribution locations, open container towards the scrubbing space direction then, so that washing lotion can be washed out cleaning agent to scrubbing space.When container was opened, this movable part can be similar to switch and begin flushing process, and when container closure, stopped described process then.Can accurately add the dissolving cleaning agent by this way and wash out the required washing lotion of cleaning agent to cleaning agent.

In the embodiment of further distortion, for example, container can be arranged in the shell that leads to scrubbing space fully movably.In situ, on the direction of the flushing scrubbing space wall of scrubbing space or shell, sidewall closes closed-cup type or grooved container.When in situ, container has been full of cleaning agent.Because container is on this position, its sidewall that points to scrubbing space will stop cleaning agent to enter shell.Therefore, can not add covering and protect cleaning agent.Thereby, can for example in the powder-type cleaning agent, prevent to have the formation that flushing process is followed the piece that stops thing or cleaning agent to work to take place too early.

In the further embodiment of the present invention, the part of container or container can rotate to distribution locations from original position.For this purpose, the movable part of container or container can be arranged movably or be rotatably mounted along serpentine track.The form of installing is simple and economical for production.

For example, the rotatable linkage that container is connected to shell can be realized in the form of two pivot bearings near the left side of the container bottom the scrubbing space wall and the right side, is incorporated in the respective recess of shell at these two pin joints that are arranged on the container.The form of installing can make container rotate towards the scrubbing space direction from shell and enter the injection phase.In described injection phase, the inside of container can be near from scrubbing space one side joint.For example, in that position, container can manually be filled cleaning agent by the user.Container relies on the retainer that is arranged on container and/or the shell to limit in the spinning movement towards the scrubbing space direction.

When injection process is finished, container will be rotated back original position and be fixed on the there.For this purpose, locking device can be arranged on the container, and itself and the pairing locking device on shell interact, and to go up in situ container are locked on the shell.Container can move to original position and be fixed on the there from the injection phase, as under the injection situation, automatically or under procedure order control or by the user manually control.

For example, all motions of a plurality of parts of container or container also can be basically by realizing with the driver of motor, coil or bimetallic devices form.For example, bimetallic devices can be based on motion temperature actuated or the execution container.This is machinery control purely.If the use motor, then it can be controlled by control device along with procedure order changes, and carries out moving of container then.

Along with container or container part in situ and moving between the distribution locations, washing lotion also can be injected into basically.Wherein corresponding with its position on the injection phase in the container position on the distribution locations.According to the further advantageous embodiments of apparatus of the present invention, second valve is arranged on the supply pipe, and second valve is used to control the volume flow and the functional container or the container part of being connected to of washing lotion.For this reason, along with container or container part motion or location, valve actuator can be moved usually.Therefore, it can be guaranteed only to wash out the necessary washing lotion of cleaning agent and enters container.

In simple embodiment variant of the present invention, second valve for example can be closed at the original position of container and open in the distribution locations of container.Therefore, have only when container and open, can guarantee that washing lotion enters container towards the scrubbing space direction.For example, this can rely on the actuation element that is arranged on the container to implement, and actuation element contacts with second valve in distribution locations, and second valve is opened then fully.When container when distribution locations moves to original position, contacting and will disconnect once more between actuation element and valve, valve will be closed.Substitute mechanical actuation elements, also can use sensor, sensor non-contiguously exploration vessel the relevant position and correspondingly rely on control device to cause that second valve opens or closes.For example can rely on electric actuator to realize opening or closing of valve.

In the further embodiment variant of the present invention, can according to container in situ and rotatablely moving between the flush position open second valve.The relevant position that this means valve actuator also can be set on each position of rotation between original position and the distribution locations.Therefore,, not only just in time have two discrete settings, but also have a plurality of settings between open position and closed position for second valve.Thereby, be used to dissolve or depend on the circumstances wash out specified quantitative the necessary washing lotion amount of cleaning agent therefore even proportional better.

Further advantageously, between the position of rotation of the valve position of second valve and container, have and connect.This connection can be mechanical, electronic or sensing.For example, mechanical attachment can connecting rod or the form of gear realize.For electrically connecting, the potentiometer that for example is arranged in container or container part pivot can be connected in electric actuator.Connect with regard to sensing, rely on the motion of one or more sensor record containers or container part, or the position of rotation that depends on the circumstances.For example, have via the connection of control module to the actuator of valve.This connection can be used in washes out the necessary washing lotion amount of cleaning agent and the container relevant position is complementary.Cleaning agent can be washed out by that way equably, or it is dissolved to depend on the circumstances.Therefore, can avoid only being dissolved in fully all interior cleaning agents of scrubbing space is washed out suddenly.

Substitute first and second valves, the only valve in conjunction with two functions also can be provided.

The specific embodiment

Fig. 1 be have scrubbing space 12 and be arranged on the wall 13 of scrubbing space 12 or within the part general diagram in washing lotion path 10 of dish-washing machine of distributor 14.The inside of scrubbing space 12 is the spraying systems 16 with single-nozzle 18.Spraying system 16 is connected to circulating pump 22 on the pressure side via pipe 20.Circulating pump 22 on the pressure side further 24 be connected in first valve 26 via pipe.First valve 26 is embodied as triple valve, has via pipe 32 to be connected in first connector 28 that is arranged in the jet blower 30 in the distributor 14.Second connector 34 of first valve 26 is connected in the jet blower 38 that is arranged in the scrubbing space 12 via pipe 36.In distributor 14, a plurality of sidewalls 40, bottom 42 and cladding element 44 are formed for the container 46 of cleaning agent (not shown).42 are furnished with the outflow opening 48 that is connected in scrubbing space 12 via pipe 50 in the bottom.

In the beginning of washing process, the fresh water of specified quantitative enters the scrubbing space 12 of dish-washing machine via inlet valve, and inlet valve is not shown in Fig. 1.The water that is also referred to as the described amount of bath foam 52 is used for cleaning then and will be washed article in the bottom section of scrubbing space 12.When by circulating pump 22 pumping bath foams 52 to the path 10

pipe

20 and 24 time, use term " washing lotion ".Flow direction by arrow A symbol washing lotion.

Circulating pump 22 absorbs washing lotion via the opening 54 of scrubbing space 12 bottoms, and is sent to spraying system 16 and is sent to first valve 26 by managing 24 by managing 20.Depend on washing procedure or procedure order, open and close the

connector

28 and 34 of first valve 26 by control module 56.As a result of, washing lotion by manage 32 and jet blower 30 be sent to selectively in the container 46 of distributor 14, and/or by manage 36 and jet blower 38 be sent to selectively in the scrubbing space 12.Because distribute back pipe 32 inoperative up hill and dale at cleaning agent, its length is because washing lotion is short in as much as possible to avoid precipitation.For this purpose, as with from shown in Figure 1 different, valve 26 can be arranged in the front of jet blower 30 with being right after.

When increasing cleaning agent, send the cleaning agent of washing lotions to the container 46 via jet blower 30.Therein, detergent is washed to scrubbing space 12 with pipe 50 by flowing out opening 48 in washing lotion and together with it.

When washing out all cleaning agents, will close first connector 28 and open second connector 34 from container.Then, only by managing 36 pumping washing lotions to jet blower 38.Do not have or the selection zone of the scrubbing space 12 that do not arrive fully will be sprayed by the concentrated area by jet blower 38 by spraying system.

Control module 56 transmits the necessary signals that is used for control valve 26.By the holding wire of dotted line 57 symbols between control module 56 and valve 26.For the reliability of strengthening cleaning, stop back connector 28 sustainable staying open in the time that is used for dispense detergent, so that still can wash out any cleaning agent remnants that remain in the container 46 up hill and dale from container 46.For this purpose, connector 28 fully or is partly opened independently or with connector 34.Therefore, wash liquid stream is divided based on the percentage between

connector

28 and 34, and therefore will motion in

pipe

24,32 and/or 36 always.This has been avoided washing lotion to keep motionless for a long time, and avoids forming in

pipe

24,32 and 36 the sedimentary risk of following.

Fig. 2 illustrates as the second alternative embodiment variant shown in Figure 1.Therefore, in Fig. 2, also as Fig. 3 and 4, identical part is designated as known reference number/letter from Fig. 1.

Different with Fig. 1, distributor 14 as shown in Figure 2 comprises having the container 46 that moves bottom 42, and bottom 42 can be by means of hinge 43 in the position of closed container 46 and open between the position of container 46 and rotate.Moving direction by arrow B symbol bottom 42.Second valve 27 also is arranged on the pipe 32 between first valve 26 and the jet blower 30.Be arranged in sensor and the valve 27 the same control modules 56 that are connected on the hinge 43.Signify at control module 56 and

valve

26,27 by dotted line, or the holding wire between the sensor that depends on the circumstances.

Sensor is the pivot sensor, and the signal of 42 corresponding position of rotation was to control module 56 bottom its transmission was assigned to.Control module 56 is determined corresponding valve position and is sent the driver of appropriate signals to the second valve 27.Therefore, when bottom 42 was closed, second valve 27 can cut out with the simplest situation, and when opened bottom 42, it was opened with the simplest situation.It is controlled that second valve 27 also can spread all over the rotating range of open circuit or the bottom 42 that depends on the circumstances.Then, second valve 27 does not just have such as " opening " and " cutting out " two discrete valve settings, but also has a plurality of settings between them.Then, the volume flow of washing lotion can rely on valve actuator to set in the rotating range that spreads all over bottom 42.So, when bottom 42 begins to open, sent a spot of washing lotion to jet blower 30.If further open bottom 42, then also will increase the volume flow of washing lotion.Then, when all open bottom 42, second valve 27 also will all be opened.Wherein, being sent to the washing lotion amount of container 46 will be always with consistent by the amount that the bottom 42 of opening drains into scrubbing space 12 from container 46.

It shown in Fig. 3 and 4 another embodiment variant according to distributor of the present invention.Different with the distributor shown in Fig. 1 and 2, container is rotation between (Fig. 3) and the distribution locations (Fig. 4) in situ here.On distribution locations, can near the one or more jet blowers the distributor wash out cleaning agent in the scrubbing space by being arranged in.

Distributor 14 is installed in the recess in the wall 13 of scrubbing space 12.Described device has the shell 17 that leads to space 12.Container 47 is installed in rotation in the described shell.The opening that points to the shell 17 of scrubbing space 12 is covered in the close mode of liquid by the sidewall 41 of container 47 fully.Before distributing, cleaning agent prevents that by this way the cleaning agent in the container 47 from contacting with washing lotion.

Fig. 3 illustrates the container 47 that is in original position, and wherein cleaning agent has been put into container 47.In described position, stop the rotation of container 47 towards scrubbing space 12 directions by the retainer (not shown).Container 47 remains on original position together with cleaning agent and moves up to the direction towards scrubbing space 12.

Wherein the motion of being finished by container 47 is rotation, or what depend on the circumstances is rotatablely moving by the moving axis 58 that rotates of arrow B symbol in Fig. 4.The position of container 47 shown in Figure 4 is distribution locations.In described position, the opening 49 of container 47 points to scrubbing space 12.As a result, cleaning agent can dash to the scrubbing space 12 of dish-washing machine from container 47.Because container 47 does not have sidewall, in distribution locations, cleaning agent can wash out from container 47 in both sides.

Container 47 remains on distribution locations up to EP (end of program), so that can wash out any cleaning agent remnants that remain in the container 47 fully from the washing lotion of jet blower 30.Because distribution locations is identical with the injection phase, to finish when refilling cleaning agent and be used for another washing procedure and be back to original position when washing procedure, container 47 can remain on described position.

Different with the distributor described in Fig. 3 and 4, the advantage that the distributor described in Fig. 1 and 2 has is, may be arranged in will being washed article and can not stoping flushing process of distributor front.Do not have movable part or only it can not move to scrubbing space according to the container of Fig. 1 and 2 yet.On the contrary, under the situation of the distributor of foundation Fig. 3 and 4, the jet blower in device is not possible yet, the result, and during washing process, all lotion pipelines will always be used.

In a word, notice this fact again, promptly the distributor 14 in aforementioned detailed description is exemplary embodiment, and it can be revised in all modes in not leaving scope of the present invention by those skilled in the art.Especially, the setting of

container

46 and 47 specific embodiments and
