Summary of the invention
According to the present invention, a kind of detergent dispensing apparatus that is used for autowash is provided, this device has: a plurality of chambers that hold composition of detergent; Alternative pack (means), this alternative pack are used for selectively making each chamber to be exposed to washing lotion, to allow in use to go out washing agent from described chamber; Manual operational unit, this manual operational unit can move to the second place from primary importance, and to load mechanical energy to described device, this mechanical energy provides restoring force for described functional unit; And return movement prevents parts, this return movement prevents that parts are used for described functional unit is remained on the described second place, this return movement prevents that arrangements of components from becoming when standing to preponderate in the machine condition of (prevailing) during the cycles of washing and moves, thereby during single cycles of washing, make described functional unit move to described primary importance or discharge described functional unit so that it turns back to described primary importance; Described functional unit is arranged to: described functional unit from described primary importance to the described second place move, from the described second place during to the motion of described primary importance or these two motions, described alternative pack and tube (cartridge) are relative to each other moved, thereby make described alternative pack advance to adjacent chamber.
Described device is designed to like this, that is, this device needs manual intervention between each cycles of washing.This has a plurality of advantages with respect to full-automatic device of the prior art.Do not need to be provided with the complicated and relatively large mechanism of WO03/073906, this mechanism can make device store the energy that is used for a plurality of circulations.In addition, described device can be more reliable than WO 01/07703, relies on the condition in the machine fully and provide energy so that device moves to the washing agent of next dosage in WO01/07703.And different with WO 03/073907 is the not danger that may distribute additional detergent dosage before the subsequent wash circulation.In case the user has manually operated described device, then functional unit just is maintained at the appropriate location until being released during operation cycle.
Described functional unit can be arranged to: during to the motion of described primary importance, make described alternative pack advance to adjacent chamber from the described second place at this functional unit.In this case, when the user operates described functional unit, can load mechanical energy and can not make described alternative pack motion to described device simply.Described return movement prevents that parts then can be designed to: operate to discharge described functional unit making it be back to described primary importance apace during cycles of washing, thereby make before the described alternative pack and then washing agent is exposed.Optionally, described return movement prevents that parts are designed to operation when cycles of washing finishes, and are used for next circulation so that washing agent exposes.
Yet preferably, described device construction becomes to operate in opposite mode, makes described functional unit be arranged to: during to described second place motion, make described alternative pack advance to adjacent chamber from described primary importance at this functional unit.When the user operates described functional unit, can load mechanical energy and described alternative pack is advanced to described device.In this case, described return movement prevents that parts are preferably designed so that: when single cycles of washing will finish, this return movement prevents that parts from operating lentamente to discharge described functional unit made it be back to described primary importance.
Can also be such situation: described return movement prevents that parts are designed to, and discharges described functional unit when this rinsing maching cools off after described rinsing maching is finished washing.For the purposes of the present invention, because this cooling stage is regarded as the part of this cycles of washing, so this is regarded as " during single cycles of washing ".Should important consideration be, the user be necessary for each cycles of washing and loads mechanical energy to this device, rather than is a plurality of CYCLIC LOADING energy as among the WO 03/073906.
Can also imagine a certain combination that draws two kinds of motions.For example, chamber can include two kinds of different washing agent, and first kind of washing agent exposes when the described second place is moved from described primary importance at described alternative pack, and second kind of washing agent exposes when described functional unit moves in opposite directions.
Dominant condition can for example be the condition such as washing lotion stream in rinsing maching.Described device can be designed to collect the washing lotion of certain mass, and in a single day described washing lotion reaches predetermined threshold just makes the latch motion.Optionally, described condition can be pH or water conductivity.Yet preferably, described return movement prevents that parts from being a thermal element, and this thermal element is arranged to move when being subjected to predetermined temperature.Described thermal element can be memory metal/memorial alloy, thermo bimetal, bimetallic snap element (snap element), shape-memory polymer or wax motor (wax motor).Described predetermined temperature is between 25 ℃ and 55 ℃ (more preferably being 38 ℃ to 40 ℃) preferably.Described return movement prevents that parts from can be a breech lock, and this breech lock selectively stops the return movement of described functional unit.Optionally, described return movement prevents that parts from can be a heat-swellable element, the motion when the operation of described functional unit of this element, but when its expansion so that described functional unit when moving, temperature just is back to its initial position up to being subjected to raising.

This can realize by different ways.
Thermal element (based on time and/or temperature) phenomenon that can be designed to have hysteresis at first.When beginning, cycles of washing activates described thermal element like this.Yet (for Temperature Hysteresis Effect) described thermal element is designed so that the not enough so that described element inactivation (de-activate) of the decline temperature between the circulation of cycles of washing and rinse, thus the activation again can not appear at rinse circulation beginning the time.In this case, described thermal element preferably has in activationary temperature about 38 ℃ to 45 ℃ and the deactivation temperature about 25 ℃ to 33 ℃.
For effect time lag, described thermal element is designed so that it only can activate once in the cycle period of washing the dishes.Usually from 30 minutes to 2 hours.
Can realize the Temperature Hysteresis Effect simulated by sheath is set around the described thermal element.This sheath is used for filling hot washing lotion from cycles of washing.This sheath preferably has little outlet opening.This little outlet opening means, between washing and the rinse circulation relatively than cold period between, this sheath keeps most hot washing lotion, this means that described thermal element can inactivation during this colder stage.
Can mechanically realize further hysteresis effect.In this case, for example, described thermal element can all be reacted to variations in temperature by using two ratchet mechanisms.Yet two ratchet mechanisms mean: only first activate circulation and make the opening of chamber of described device change; Second activation is invalid by second ratchet.
For the wax motor, the fusing of wax self and solidifiability can be used for lagging behind, and this is because the wax of certain type shows and melts slow the solidifying of comparing.
And, can realize that hysteresis effect, its weight by collected water stop the wax motor to carry out second motion by water collector (have little/slowly release water hole) for the wax motor.Described water collector preferably emptied in one hour at 20 minutes.
If described chamber includes washing agent and rinse aids (the two is used for being discharged into their respective cycle), then described thermal element is preferred in the activation of these two circulations.
Usually, member comprises the mechanism that resets that adapts to this possibility automatically, and this possibility is that the consumer is interrupted the operation of autowash during cycles of washing.

The specific embodiment
Device of the present invention can be the self-supporting device that is inserted into movably in the dish-washing machine, perhaps can be embedded at (for example, in the door) in the dish-washing machine.
Fig. 1 (a) shows the detergent dispensing apparatus 1 that only comprises for background technology to Fig. 1 (c).This device 1 comprises cylindrical circular housing 2, and this housing has and covers 3 and base 4.
In housing 2 internal placement tube 5 is arranged.Tube 5 also is based on columnar.Tube 5 has center hub 6 and peripheral 7.Be furnished with a plurality of branches (limb) 8 at regular intervals, described branch is from hub 67 extensions to the periphery.Branch 8 is used for the central authorities of tube 5 are divided into a plurality of wedge-like chambers 9.Cover 3 described chamber is separated from each other thereby branch 8 extends to always.Shown in view in be clearly shown that 14 chambers 9, be understood that quantity can be changed over shown in 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 that entering hole 12 contiguous suitable chambers 9 arranges.This can by fully manually or described in the example of back by using automatic member to realize.This complete manual operation is not based on the present invention.This device 1 can be inserted in the autowash (for example automatic dish-washing machine) then.In use, by entering hole 12 washing lotion is introduced in the contiguous chamber 9.The washing lotion that is entered contacts with any washing agent of existence in the chamber 9, and by discharge orifice 10 washing agent is gone 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 described unidirectional dispensing orifice in use is positioned at the bottom of housing.
As shown in the figure, described unidirectional dispensing orifice 13 is realized this function by arranging baffle plate 14, and the liquid that these baffle plates 14 allow to be loaded with washing agent distributes from described device 1 under the effect of gravity.Yet, all turn back through via hole 13 usually by baffle plate by any washing lotion of hole 13 accesss to plant 1.Overall downward stream by described device also is used to go out any stream of not expecting like this.Between the bottom of tube 5 and base 4, be provided with the gap, so that the washing agent in the non-selected chamber is kept away from liquid in the housing bottom (backflow of not expecting or the stream by selected chamber).
Fig. 2 (a) shows first embodiment according to detergent dispensing apparatus 1 of the present invention to Fig. 2 (c).Similar to last embodiment, housing 2 and tube 5 be circular/columnar.Housing 2 has clip 2A, and this clip is used to be connected on the interior basket of machine to keep this device upright.Described tube has the structure similar to the tube of preceding example, will provide difference below.The main distinction of comparing with first example is that the lid 3 that can manually rotate is substituted by more complicated mechanism.
Tube 5 can not be with respect to lid 3 rotations.As an alternative, can enter chamber 9 in order to make washing lotion, described device comprises the collection funnel 21 with the rotatable guiding mouth of pipe (directing spout) 22 cooperations.
In operation, the washing lotion that is entered is collected in the funnel 21 and can flows to the guiding mouth of pipe 22.The guiding mouth of pipe 22 has the mouth of pipe outlet 23 of washing lotion being guided into single chamber 9.For continuous cycles of washing/continuous operation, make the funnel 21 and the guiding mouth of pipe 22 all with respect to tube 5 rotations, thereby can enter continuous chamber 9.
For funnel 21 is rotated, the user resists biasing spring 25 and push button 24.When push button 24, the lug 26 on the arm 27 that hangs from button 24 engages with the groove 28 in the central opening that is arranged in funnel 21.Button 24 non-rotatably is installed in and covers in 3, and owing to the vertical axis of groove 28 with hub 6 tilts angledly, so pressing of button 24 causes funnel 21 (and the relevant guiding mouth of pipe 22) rotation in housing 2 that is supported on the support wheel 21A.
The rotation of funnel 21 in housing 2 makes: the washing lotion that is entered can enter the continuous cavity 9 (that is, groove 28, lug 26 and arm 27 are arranged to: pressing fully of action button 24 causes funnel 21 rotations, so that continuous cavity 9 enters operating position) of tube 5.
For how many chambers that helps the user to know tube 5 also has, lid 3 comprises window 29.By this window 29, the user can see the part of funnel 21.Finding partly preferably includes and the numbering of employed chamber 9 or the relevant numeral of numbering of residue chamber 9 (that is the chamber 9 that, still includes washing agent).
Biasing spring 25 preferably is made of bimetallic material.In use, when pressing the button 24 before cycles of washing begins, button 24 can not turn back to its initial position.This can not return function and help to prevent unexpected multi-pass operation device 1.When finishing near cycles of washing, along with the increase of temperature in rinse and/or the drying cycles, thereby spring 25 activated and makes button 24 turn back to its initial position.
When button 24 turns back to its initial position, prevent funnel 21 reverse rotations by two mechanisms.At first, the ratchet mechanism (not shown) prevents rotation.Secondly, arm 27 preferably has elasticity, thereby when moving upward, arm curves inwardly and can not engage with groove 28.
When the last chamber 9 with tube 5 placed its operating position, the guiding mouth of pipe 22 engaged with " not-go-end portion (end-stop) ", thereby funnel 21 can not carry out any being further rotated.In this position, if action button 24, then lug 26 is only crossed groove 28 simply by means of the deflection of arm 27.
When having used last chamber 9, can be by more creeling 5 of user.
As clearly visible from Fig. 2 (c), tube 5 is different with the structure of Fig. 1.Specifically, the inlet 5A of each chamber 9 no longer is positioned at the end wall place of tube, but is positioned at the radially inside place, top towards wall towards hub 6, thereby aims at the mouth of pipe 22.Be provided with the 5B of dam portion (weir) between inlet 5A and washing agent 5C, to stop a spot of water, these water can be drawn towards the not chamber 9 of choosing when contacting with washing agent.That replace axially spaced discharge orifice 10 is single hole 5D in the chamber bottom surface.In order to help the washing lotion ensemble stream to cross chamber 9, between the inwall of the radially outermost edge of washing agent 5C and tube 5, be provided with space 5E.In addition, in washing agent, be provided with one or more axially extended through hole 5f, so that flow.
And for the way flow of bleeder bottom is provided, outlet 13 is at this moment towards the peripheral of device and with respect to the sizable amount of outlet 5D radial deflection.And baffle plate 14 can be by exporting any backflow of not expecting of 13 guiding.
Fig. 3 (a) shows second embodiment of detergent dispensing apparatus 1 to Fig. 3 (d).Similar to first embodiment, housing 2 and tube 5 be circular/columnar.This device has the mouth of pipe similar to first embodiment and tube.Yet, the mode of operation difference of button.
Device 1 have the guiding mouth of pipe 22 that is the ratchet form (the guiding mouth of pipe 22 preferably with collection funnel 21 (not shown, but as Fig. 2 (a) to Fig. 2 (c) described) cooperate).The described guiding mouth of pipe has mouth of pipe outlet.In operation, the washing lotion that enters is collected in the funnel and can flows via the guiding mouth of pipe 22.For continuous cycles of washing/continued operation, make the guiding mouth of pipe 22 with respect to tube 5 rotations, thus can be near continuous chamber 9.
Below with reference to coming operation is described from Fig. 3 (b) to a series of situations of Fig. 3 (d).Button 24 is designed to by operating with engaging of dish washing machine door, rather than operates by operator's hand to Fig. 2 (d) as Fig. 2 (a).This device need be positioned in the dish-washing machine, pushes button thereby close Shi Menhui when door.
In Fig. 3 (b), dish-washing machine the door be open and dish-washing machine be cold.At this state, the user can fill household utensil to dish-washing machine, needs to the greatest extent and opens and closes dish washing machine door frequently, to load dish-washing machine fully.
When closing dish washing machine door first, action button 24 is pressed by (button 24 spring biased and away from device), and remains on down state by means of the first arm 30A (referring to Fig. 3 (c)).
The first arm 30A and bimetal strip 31 1 biconditional operations.Bimetal strip 31 is the form of covering the blade on 3 that is installed in.Bimetal strip 31 has from its bar 32 of extending of installation end not.
The first arm 30A ends at flange 33.
When described door is closed (thereby making button 24 towards device 1 motion), arm 30A inwardly moves towards bimetal strip 31.Flange 33 engages through the rear and with bar 32.This joint is locked in correct position with action button 24: further opening of dish washing machine door can not cause button 24 motions.
Shown in Fig. 3 (d), the dish-washing machine operation begins.As result's (intensification) of this operation, bimetal strip 31 is converted to its condition of high temperature.Such effect is that bar 32 no longer engages with flange 33 until it away from the first arm 30A motion.
Because flange 33 no longer engages with bar 32, so arm 30A lateral movement.In case dish washing machine door is opened, then this moment, action button 24 was with regard to freely-movable.Like this, when dish washing machine door was opened, button 24 just moved away from described device by the back-moving spring (not shown).
The second arm 30B (being connected on the button 24) that is bar pawl (lever pawl) form engages with the guiding mouth of pipe 22.The outside motion of button 24 and the arm 30B of connection cause the guiding mouth of pipe 22 further to move.Like this, the orientation of the guiding mouth of pipe 22 is changed, thereby make the new chamber 9 of tube 5 enter the operating position that is used for next dishwasher cycle.
If dish-washing machine is not opened (and thereby cooling down) in a period of time, then prevent rejoining (may cause this rejoining) of stopping bar 32 and flange 33 because bimetal strip 31 is back to the motion of its low temperature structure by the motion of arm 30A through bar 32.
The 3rd arm 30C provides the biasing force of the opposing mouth of pipe 22, to prevent described mouth of pipe reverse rotation when the second arm 30B breaks away from this mouth of pipe.
When having used all chambers 9 of tube 5, prevent to guide the further motion of the mouth of pipe 22 (and thereby tube 5) by lug (not shown) on the guiding mouth of pipe 22 and engaging of pawl (not shown).
Fig. 4 (a) shows the 3rd embodiment of detergent dispensing apparatus 1 to Fig. 4 (e).
The 3rd embodiment and second embodiment are closely similar.To only describe substantive difference in detail below.And the washing agent tube is such as previously described.
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 operation is described below 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 with the guiding mouth of pipe 22, and makes 22 rotations of the guiding mouth of pipe, so that the new chamber 9 of tube 5 enters operating position.
And shown in Fig. 4 (b), the flange 33 on the arm 30A engages with the bar 32 that covers in 3.Under the situation that dish washing machine door is opened (for example, during cycles of washing), this of flange 33 and bar 32 engages the further motion that prevents button 24.
Device 1 comprises the bimetal strip 31 that is the bent stick form, and this burr is around the first installation portion 34A and be installed in around this first installation portion 34A, and against the second installation portion 34B.
During cycles of washing, when the temperature in the dish-washing machine rose, bimetal strip 31 changed to its thermal structure: through arm 30A and drop on down thereafter just, to engage (referring to Fig. 4 (c) and Fig. 4 (d)) with flange 33.
When dish-washing machine cooled off after cycles of washing, bimetal strip 31 returned to its low temperature structure.For this reason, it makes flange 33 break away from bar 32 (referring to Fig. 4 (e)).By this disengaging, button 24 is freely away from device 1 motion.Therefore, arm 30B is ready to next operation with respect to 22 motions of the guiding mouth of pipe so that install 1.
Fig. 5 (a) shows the modification of the thermal control structure that can use with device of the present invention to Fig. 5 (e).
This structure comprises the action button 24 (it can be manually actuated or pass through door operation) that is connected to arm 30.Arm 30 can operating means 1 an element, perhaps can be simply provide restriction to the operation of button 24.Described arm has heel (heel) 36.
Bimetallic element 31 (being snap disk (snap disc) form here) has relative framework 37.
Framework 37 comprises arm 38 and pawl 39.
In use, resist biasing spring 25 and press the button 24.This causes arm 30 with respect to pawl 39 motions, so that heel 36 engages (opposing biasing spring 42) at lower tooth 41A place.As the result of this joint, button 24 is maintained at its actuated position, and no matter whether dish washing machine door is opened and/or whether the user attempts further actuating.
When dish-washing machine was operated, the temperature of dish-washing machine rose, thereby the temperature of whole device 1 also rises.By the rising of this temperature, snap disk 31 changes to its thermal structure.This change makes the part that is connected to snap disk 31 of frame arm 38 raise.The other end of frame arm 38 reduces (pivoting about axis 40), thereby pawl 39 reduces.Such effect is, disconnected engaging of heel 36 and lower tooth 41A.Heel 36 then engages with last tooth 41B, and the biased spring 42 of heel is pushed tooth 41B to.
When dishwasher cycle finishes and during dishwasher cools down (may opening by means of dish washing machine door), snap disk 31 returns to its low temperature structure.Such effect is that last tooth 41B rises from heel 36, up to the joint disconnection of heel 36 and last tooth 41B.
Because heel 36 is not subjected to further confining force, the spring bias voltage that therefore act as opposing button 24 can back into its unactuated position with button 24.
