WO 03/073907 discloses a kind of self-supporting distributor of analogous shape.For dispense detergent, manual operation one control lever comes mobile blister package, thereby or with the compartment ejection of washing agent in the blister package, perhaps pierce through blister package.Play junior one door or baffle plate (flap) and prevent that the washing lotion in the machine from entering the washing agent that exposes.One bimetal strip is arranged to: described door or baffle plate are moved, entering the washing agent that exposes to allow washing lotion, thereby washing agent is distributed to machine.
Summary of the invention
The present invention relates to the improvement of these self-supporting devices.
According to the present invention, a kind of self-supporting detergent dispensing apparatus that inserts autowash removedly is provided, this device comprises: tube (cartridge), this has a plurality of unencapsulated chambers that hold composition of detergent; Guider, this guider optionally imports washing lotion the chamber of described tube, thereby described washing lotion is contacted with composition of detergent in the described chamber, and each chamber has the inlet that is the zigzag path form, flows into unselected chamber to stop unwanted washing lotion.
The invention provides a kind of the substituting of blister package type structure of the sealing to prior art.Although it is unencapsulated the invention reside in described device is designed to each chamber, tolerance makes the overall flow of water be kept away from unselected chamber usually.In a single day described inlet is the part that the water most probable of described chamber enters, and is exactly the zone that guides water to enter because selected described chamber, described inlet.Thereby by zigzag path is set, the overall flow that enters the water of selecting compartment is enough to find its route along described zigzag path, but has stoped the low-level of the unselected compartment that may bleed to be flowed.Such structure compare with the described packing bubble-cap structure of prior art manufacture much cheap.
Preferably, described zigzag path comprises the unwanted mobile dam portion (weir) that stops.
Preferably, described device has the public outlet from all described chambers, and this outlet only allows basic one-way flow.
Described outlet can be provided with the check valve that allows described one-way flow.Yet described outlet preferably is provided with the zigzag path that allows described one-way flow, like this can be for example by molded and easily in this device, constructing a path during the manufacturing of described device.Preferably, described outlet has a plurality of dividing plates that are used to make the liquid that enters described outlet to turn back to flow out described outlet.
Preferably, described tube separates with described outlet.Like this, if a spot of washing lotion enters described outlet, this washing lotion will be contained in the space, thereby prevent that it from entering unselected chamber.
Described guider can be anyly to be used for optionally making chamber to be exposed to the mechanism of the washing lotion of machine.Yet preferably, described guider has the opening of optionally aiming at each chamber.For example described guider can comprise a film, and this film comprises the linear described opening of aiming at a chamber that moves or rotatably move to.Yet preferably, described guider comprises and can rotate to the mouth of aiming at the opening that leads to corresponding chambers (spout).This mouth is preferably designed to and stops that described washing lotion enters unselected chamber.
Preferably, described device is provided with the funnel that leads to described guider.This has increased the washing lotion amount that can import selected chamber.
Described guider or tube can manually move.In other words, described moving can be controlled by the user fully.Perhaps described device can be automatic fully,, carries out in continuous cycles of washing that multiple dosage distributes and the intervention that do not need the user that is, as disclosed among for example WO 01/07703 and the WO03/073906.Perhaps described device can be " semi-automatic ".In this case, some that needs the user in the operating period of described machine gets involved to move described guider or tube, subsequently it reset.Perhaps can reset described guider or tube, move it subsequently the operating period of described machine user.
Under the situation of automatics or semiautomatic plant, described device preferably is arranged to the parameter (for example, pH, electrical conductivity of water, water quality, door operation) that the operating period at described machine exists is reacted.
Preferably, described device comprises that thermal reaction element and described parameter are temperature.Described thermal reaction element can be any in memory metal/memorial alloy, thermo bimetal, bimetallic snap element (snapelement), shape-memory polymer or the wax motor (wax motor).Described element is preferably designed at (more preferably between 38 ℃ to 40 ℃) between 25 ℃ and 55 ℃ and reacts.Described element can be designed to react as early as possible, if described device has manually reset and must automatically move, more than just may be essential.Yet if described device moves automatically and resets by described thermal element, described thermal element preferably has hysteresis effect (historisis effect).This has postponed the operation of described thermal element, thereby guarantees that described device can not reset at the early part of the cycles of washing of described machine, but only just resets when in a single day described machine executes whole washing process.
This can realize with multitude of different ways.
At first, thermal element can be designed so that it has hysteresis effect (based on time and/or temperature).Described like this thermal element activates when cycles of washing begins.Yet, (for Temperature Hysteresis Effect), described thermal element is designed so that the not enough so that described element inactivation (de-activate) of the temperature that reduces between cycles of washing and rinse cycle, thereby can not take place to activate again when rinse cycle begins.In this case, described thermal element preferably has about 38 ℃ to 45 ℃ activationary temperature and about 25 ℃ to 33 ℃ deactivation temperature.
For effect time lag, described thermal element is designed so that it only can be activated once during dishwasher cycle.Normally from 30 minutes to 2 hours.
Can realize the Temperature Hysteresis Effect simulated by an outer cover (jacket) is set around the described thermal element.Described outer cover is intended to charge into hot washing lotion from cycles of washing.Described outer cover preferably has little outlet opening.This little outlet opening means that between cycles of washing and rinse cycle in the relative colder stage, described outer cover keeps most of described hot washing lotions, this means that described thermal element can inactivation during this colder stage.
Can mechanically realize another hysteresis effect.In this case, for example by using two ratchet mechanisms that described thermal element can be reacted to both variations in temperature.Yet two ratchet mechanisms only mean that first activates circulation and make the described opening of chamber of described device change; Second ratchet makes second activation invalid.
For the wax motor, the fusing of wax itself and solidify character and can be used for lagging behind is solidified with fusing and is compared slowly because the wax of some type shows as it.
And, can prevent that the wax motor from carrying out second water collector that moves (having little/slow dewatering orifice) and realizing hysteresis effect by the weight of utilizing the water of collecting for the wax motor.This water collector preferably 20 minutes to one hour in the turned letter.
If described chamber comprises washing agent and rinse aids, the both is used for being discharged into their circulations separately, and it is favourable then activating described thermal element in two circulations.
Usually self-winding parts comprises the mechanism that resets that adapts to this possibility, and described possibility is that the consumer is interrupted the operation of autowash during cycles of washing.
Under the situation of hand-operating device or " semi-automatic " device, manual-operating mechanism can constitute the hand operated by the user, perhaps can constitute the door operation by described machine.
Described guider or described tube can be arranged to removable to select detergent doses.Yet preferably, described guider is arranged to removable, because required like this energy is littler than moving the described required energy that is filled with washing agent.
Preferably, described tube can remove from described device, sells thereby make described tube can be used as field-replaceable unit, and this is inserted into inside and is provided with in the described device of described guider.
Described device is preferred for automatic dish-washing machine.Therefore described washing agent most preferably comprises the automatic dish-washing machine washing agent.The example of described automatic dish-washing machine washing agent comprises the conventional washing agent, and " 2 close 1 " and " 3 close 1 " modification.Most preferably, described washing agent comprises solid.In the context of the present invention, described term " solid " can be considered the gel that comprises curing and traditional solid material (for example fusion/cross-linked material of Ya Suo granular materials and curing).
The prescription of described washing agent (formulation) generally includes one or more in the following component: builder, common builder, surfactant, bleaching agent, bleach activator, bleaching catalyst, enzyme, polymer, stain, colorant, aromatic, water and organic solvent.
The optional detergent additives that comprises of described washing agent.Should be understood that in the different piece of dish-washing machine washing circulation comparing with washing agent to need detergent additives (for example rinse cycle needs the rinse aids detergent additives).
In fact, the continuous cavity of described tube can be filled different composition of detergent.For example, be used for to comprise " washing prescription ", and second chamber of contiguous described for simplicity first chamber location can comprise and is used for the rinse aids prescription that distributes in the rinse cycle of automatic dish-washing machine at first chamber that the cycles of washing of dish-washing machine is distributed.
Described chamber can be divided into sub-chamber, and each sub-chamber is exposed to described washing lotion simultaneously, with the stability of the incompatible composition (that is, enzyme and bleaching agent) of guaranteeing described washing agent.
Should be understood that in the described situation of above paragraph, described first and second chambers can vary in size, to adapt to their different purposes.
Described washing agent can add described tube to by any suitable method.Described washing agent can by manually, cast (casting) or injection moulding adds described tube to.

The specific embodiment
Fig. 1 (a) is to Fig. 1 (c) expression detergent dispensing apparatus 1.Device 1 comprises housing 2, and this housing 2 is to have and covers 3 and the drum forms of base portion 4.
In housing 2, be furnished with tube 5.Tube 5 is also based on a cylinder.Tube 5 has center hub 6 and periphery 7.Be furnished with a plurality of branches (limb) 8 that extend to periphery 7 from hub 6 with even interval.Branch 8 is used for the central authorities of tube 5 are divided into a plurality of wedge shape chambers 9.Branch 8 extends to always and covers 3, thereby described chamber is separated from each other.Shown in figure in clearly have 14 chambers 9, should be understood that chamber quantity can with illustrate different.
Described chamber is used to fill the composition of detergent (not shown).
The periphery 7 of each chamber 9 has a plurality of discharge orifices 10.
In use, described drop cloth is set to and makes ingate 12 contiguous suitable chambers 9 arrange.This can fully manually finish or finish by the automatic element that use will be described in following example.Device 1 can be inserted autowash (for example automatic dish-washing machine) then.In use, by ingate 12 washing lotion is imported adjacent cavity 9.The washing lotion that enters contacts with any washing agent of existence in the chamber 9, and by one of them discharge orifice 10 washing agent is washed out chamber 9.The washing lotion of Jia Zaiing flows through the space between tube 5 and the housing 2 like this, and leaves housing 2 by unidirectional dispensing orifice 13, and unidirectional dispensing orifice 13 in use is positioned at the bottom of housing.
As shown in the figure, unidirectional dispensing orifice 13 is realized this function by arranging dividing plate 14, and these dividing plates 14 distribute the liquid that is loaded with washing agent from installing 1 under the gravity effect.Yet any washing lotion by hole 13 accesss to plant 1 is totally all turned back by hole 13 under spacer function.Overall the flowing downward of passing this device also is used to wash out any unwanted like this flowing.Between the bottom of tube 5 and base portion 4, be provided with the gap, thus the washing agent in the non-selected chamber keep with housing bottom in liquid (unwanted backflow or by selected chamber mobile) separate.
Fig. 2 (a) is to second embodiment of Fig. 2 (c) expression detergent dispensing apparatus 1.Identical with first embodiment, housing 2 and tube 5 be circular/columnar.Housing 2 has on the basket that is used to be attached in the machine with the upright clip 2A of holding device.Described tube has and structure like first example class, and difference will be in following elaboration.The main difference of comparing with first example is, has replaced manual rotatable lid 3 by more complicated mechanism.
Tube 5 can not be with respect to lid 3 rotations.What the permission washing lotion that replaces entered chamber 9 is that described device comprises the collection funnel 21 with rotatable guiding mouth 22 cooperations.
In operation, the washing lotion that enters is collected in the funnel 21 and can flows to guiding mouth 22.Guiding mouth 22 has the lead mouth outlet 23 of single chamber 9 of washing lotion.For continuous cycles of washing/continuous operation, make funnel 21 and guiding mouth 22 all with respect to tube 5 rotations, thereby can insert continuous chamber 9.
In order to realize the rotation of funnel 21, the user overcomes biasing spring 25 and push button 24.When push button 24, the projection that is attached to button 24 26 on the arm 27 engages with groove 28 in the central opening that is arranged in funnel 21.Button 24 non-rotatably is installed in and covers in 3, and because the vertical axis of groove 28 and hub 6 tilts an angle, so pressing of button 24 makes the funnel 21 (with relevant guiding mouth 22) that is bearing on the bogie wheel 21A rotate in housing 2.
The rotation of funnel 21 in housing 2 makes the washing lotion that enters can enter the continuous cavity 9 of tube 5 (that is, groove 28, projection 26 and arm 27 are arranged to: pressing fully of action button 24 causes funnel 21 rotations, thereby makes continuous cavity 9 reach operating position).
For how many chambers that helps the user to understand tube 5 also remains, lid 3 comprises window 29.By window 29, the considerable part of seeing funnel 21 of user.Viewed part preferably comprise with use in the quantity of chamber 9 or the relevant numeral of quantity of remaining chamber 9 (that is the chamber 9 that, still contains washing agent).
Biasing spring 25 preferably includes bimetallic material.In use, when pressing the button 24 before cycles of washing begins, button 24 does not return its initial position.Thisly do not return the unexpected multiple operation that function helps anti-locking apparatus 1.When finishing near cycles of washing, because the temperature in rinsing and/or the drying cycles increases, spring 25 is activated and makes button 24 return its initial position.
When button 24 returns its initial position, prevent the contrary rotation of funnel 21 by two mechanisms.At first, the ratchet mechanism (not shown) prevents rotation.Secondly, arm 27 preferably has elasticity, thereby described arm curves inwardly and do not engage with groove 28 when moving upward.
When the last chamber 9 of tube 5 placed its operating position, guiding mouth 22 engaged with " not-go-end portion (end-stop) ", thereby funnel 21 can not be further rotated.In this position, if action button 24, then projection 26 is only by the deflection of arm 27 and cross groove 28.
When last chamber 9 has used, the replaceable tube 5 of user.
As obviously seeing among Fig. 2 (c), different among tube 5 structure and Fig. 1.Specifically, the inlet 5A that leads to each chamber 9 no longer is positioned at the end wall place of tube, but is positioned at towards the place, top of the wall of the radial inward of hub 6, thereby aims at mouth 22.Between inlet 5A and washing agent 5C, be provided with the 5B of dam portion, contact with washing agent with the low amounts of water of the non-selected chamber 9 that prevents to lead.Replace axially spaced discharge orifice 10 by the single hole 5D in the chamber bottom surface.For the overall flow that helps washing lotion by chamber 9, between the radially outermost edge of washing agent 5C and tins 5 inwall, have space 5E.In addition, being provided with one or more axially extended through hole 5F in washing agent flows helping.
And for the one-way flow of bleeder bottom is provided, outlet 13 is at this moment towards the periphery of device and with respect to the sizable amount of outlet 5D radial deflection.And dividing plate 14 passes outlet 13 with any unwanted backflow guiding.
Fig. 3 (a) is to the 3rd embodiment of Fig. 3 (d) expression detergent dispensing apparatus 1.Identical with first and second embodiment, housing 2 and tube 5 be circular/columnar.This device has and similar mouth of second embodiment and tube.Yet, the mode difference of action button.
With reference to a series of situations this operation is described from Fig. 3 (b) to Fig. 3 (d).Button 24 is designed to by engaging with dish washing machine door rather than operating to the hand of the operator shown in 2 (c) by Fig. 2 (a).This device need be positioned in the machine like this, so that door presses the button when closing.
In Fig. 3 (b), dish washing machine door is opened and dish-washing machine is cold.At this state, user's household utensil of can packing in dish-washing machine needs ground often to open and close dish washing machine door to load dish-washing machine fully to the greatest extent.
When dish washing machine door was closed for the first time, action button 24 was pressed (button 24 is spring biased away from device) and remains on down state (seeing Fig. 3 (c)) under the effect of the first arm 30A.
The first arm 30A and bimetal strip 31 are operated in combination.Bimetal strip 31 is the form that is installed in the blade (blade) that covers on 3.Bimetal strip 31 has from its bar 32 of extending of mounting end not.
The first arm 30A ends at flange 33.
When door was closed (thereby button 24 is moved towards device 1), arm 30A inwardly moved towards bimetal strip 31.Flange 33 process bar 32 rears also engage.This joint is locked in the appropriate location with action button 24: further opening of dish washing machine door can not make button 24 move.
Shown in Fig. 3 (d), the operation of dish-washing machine begins.As the result of operation (temperature rising), bimetal strip 31 becomes its condition of high temperature.Such effect is: bar 32 moves up to it away from the first arm 30A and no longer engages with flange 33.
Because flange 33 no longer engages with bar 32, so arm 30A is displaced sideways.In case this moment, dish washing machine door was opened, action button 24 just can move freely.Thereby when dish washing machine door was opened, button 24 moved away from device under the effect of back-moving spring (not shown).
The second arm 30B (being attached on the button 24) that is bar pawl (lever pawl) form engages with guiding mouth 22.Button 24 and appended outwards moving of arm 30B are moved further guiding mouth 22.The orientation of guiding mouth 22 changes like this, thereby places operating position in order to next dishwasher cycle the new chamber 9 of tube 5.
If dish-washing machine is not opened (thereby cooling) in a period of time, then mobile anti-stopping bar 32 and the flange 33 by arm 30A process bar 32 engages (this engages possibility again because bimetal strip 31 is got back to mobile the causing that its low temperature is constructed) again.
When the second arm 30B and the disengaging of described mouth, the 3rd arm 30C provides the biasing force of opposing mouth 22 to prevent the contrary rotation of mouth.
When all chambers 9 of tube 5 have used, prevent that by projection (not shown) on the guiding mouth 22 and engaging of pawl (not shown) guiding mouth 22 (thereby preventing tube 5) is moved further.
Fig. 4 (a) is to the 4th embodiment of Fig. 4 (e) expression detergent dispensing apparatus 1.
The 4th embodiment and the 3rd embodiment are closely similar.To only describe essential distinction in detail.Equally, the washing agent tube as mentioned above.
The main distinction is the operation of arm 30A and 30B and the operation of bimetal strip 31.
With reference to a series of situations this operation is described from Fig. 4 (a) to Fig. 4 (e).
In Fig. 4 (a), dish-washing machine is cold and dish washing machine door is opened.
In Fig. 4 (b), dish washing machine door is closed.Arm 30B engages and makes guiding mouth 22 rotations with guiding mouth 22, thereby makes the new chamber 9 of tube 5 reach operating position.
Also shown in Fig. 4 (b), the flange 33 on the arm 30A engages with the bar 32 that covers in 3.This of flange 33 and bar 32 engages and prevent that button 24 when dish washing machine door is opened, for example is moved further during cycles of washing.
During cycles of washing, when the temperature in the machine raise, bimetal strip 31 became its high temperature configuration, and process arm 30A also falls to its rear, thereby engages (Fig. 4 (c) and Fig. 4 (d)) with flange 33.
When machine cooled off after cycles of washing, bimetal strip 31 returned its low temperature structure.This moment, it made flange 33 and bar 32 break away from (Fig. 4 (e)).By this disengaging, button 24 moves freely away from device 1.Thereby arm 30B moves with respect to guiding mouth 22, makes device 1 be next ready for operation.
The modification of the thermal control structure that Fig. 5 (a) can use with device of the present invention to Fig. 5 (e) expression.
This structure comprises the action button 24 that is connected to arm 30 (but manual operation or by door operation).But the element of arm 30 operating means 1 or restriction to the operation of button 24 can only be provided.This arm has heel (heel) 36.
Bimetallic element 31 (form that is snap disk (snap disc) herein) has relative framework 37.
Framework 37 comprises arm 38 and pawl 39.
Frame arm 38 is connected to the central authorities of snap disk 31.Part along frame arm 38 is furnished with pivot 40.Pawl 39 is positioned at the other end of frame arm 38.
Pawl 39 is arranged around the heel 36 of arm 30.Pawl 39 has and is intended to and heel 36 synergistic lower tooth 41A and last tooth 41B.Last tooth 41B is arranged to more farther apart from pivot 40 than lower tooth 41A.
In use, overcome biasing spring 25 and press the button 24.This makes arm 30 move with respect to pawl 39, thereby heel 36 engages (overcoming biasing spring 42) at lower tooth 41A place.Whether as the result of this joint, button 24 remains on its active position, and open and/or whether the user attempts further to activate irrelevant with dish washing machine door.
When dish-washing machine was operated, the temperature of dish-washing machine increased, thereby the temperature of whole device 1 increases.Because this temperature increases, snap disk 31 becomes its high temperature configuration.This change raises the part that is connected to snap disk 31 of frame arm 38.The other end of frame arm 38 reduces (pivoting around pivot 40), thereby pawl 39 reduces.Such effect is: make the cut-out that engages of heel 36 and lower tooth 41A.Heel 36 biased springs 42 tooth 41B promotion up then, thus heel 36 engages with last tooth 41B.
Finish and during dishwasher cools down (may opening by means of dish washing machine door), snap disk 31 returns back to its low temperature structure in dishwasher cycle.Such effect is: go up tooth 41B and raise away from heel 36, up to the engage disconnection of heel 36 with last tooth 41B.
Because heel 36 no longer is subjected to confining force, so the biasing spring that acts on the button 24 can push back to button 24 its un-activation position.
