4 flow exports 39 are connected with cleaning device 27 by purge path 43 separately.In addition, also be provided with to the flow export 39 that is connected with peristome 42 is switched and drive the drive motors (motorized motions source) 54 that valve body 41 rotates, the motor shaft 55 of this drive motors 54 is keeping keeping transmission to connect with valve body 41 under the state in gap.

In addition, accompanying drawings such as Fig. 3 are conceptual diagram, and the structure of actual valve casing 40 is to be divided into 2 parts up and down, combine by screw mode such as fix, insert connection, weld and weld.In addition, be to be formed from a resin etc. under the occasion at rinse bath 22, also can constitute the part of the valve casing 40 that forms one with it with the bottom surface of rinse bath 22.

At first the basic operation to the dish cleaning machine in the above-mentioned formation describes.Tableware etc. is cleaned thing 23 installs in the tableware basket 24, put into rinse bath 22.After putting into washing agent, close and call 21, the open portion of dish cleaning machine main body 20 is closed the beginning cleaning operation.Carry out and wash the cleaning step that cleans the dirt on the thing 23 off, rinse out the rinsing step of the washing agent that adheres to and leftovers successively and make attached to the drying steps that cleans the water droplet drying on the thing 23.

At first, water intaking valve 25 is opened, and injects the washings of ormal weight in rinse bath 22, scavenging pump 26 with the washings pressurization after, from cleaning device 27 washings are ejected.At this moment, the heaters 30 such as armored heater that are located in the rinse bath 22 are energized, Yi Bian make the washings heating, Yi Bian carry out cleaning process.In addition, the temperature of 31 pairs of rinse baths 22 of temperature sensor detects, and when temperature is setting when above, then stops to heater 30 energisings.

Washings are inhaled into after by leftovers filter screen 29 in the scavenging pump 26, are supplied in the cleaning device (washer jet) 27 that is located on rinse bath 22 inner bottom parts by scavenging pump 26 then.Then, washings eject from cleaning device 27, tableware etc. is cleaned returns discharge outlet 28 after thing 23 cleans, and circulate with top path again.At this moment, the leftovers that is washed on being cleaned thing 23 etc. flows into the leftovers filter screen 29 with washings, and the big leftovers that can't pass leftovers filter screen 29 is captured by leftovers filter screen 29.

After the cleaning step of stipulated time finished, the washings that contain dirt were arranged outside machine by draining pump 32, and new washings reinject.Scavenging pump 26 is started working once more, ejects washings once more from cleaning device 27, will rinse well attached to things such as washing agent on the cleaning thing 23 and residual dishes.Through after the operation of stipulated time, washings are discharged, re-inject washings.Such operation is carried out repeatedly, and rinsing step carries out about 3 times continuously.At last, washings are discharged to outside the machine, rinsing step is finished.

Then carry out drying steps, make air blast 33 work, outer gas is sent in the rinse bath 22 by air-supply path 34, discharge from exhaust outlet 35 again.At this moment, heater 30 is energized, and impels attached to the water-drop evaporation that cleans on the thing 23 by the effect of air blast and heating two aspects.Drying steps after carrying out official hour, end operation.

Next, be that operation, the effect of division box 37 is described to the characteristic component part of present embodiment.As shown in Figure 4, valve casing 40 is slightly cylindrical, and its axis direction roughly is arranged on the vertical direction, and the inflow entrance 38 that the washings that confession was pressurizeed by scavenging pump 26 flow into is located at the lower end of valve casing 40, and flow export 39 is arranged on the upper surface of valve casing 40.Valve body 41 slightly is writing board shape, and the face A (face relative with valve body 41) that wherein is provided with flow export 39 is flat shape.

Valve body 41 and motor shaft 55 keep transmission mutually with the state that is keeping certain interval, valve body 41 except rotational action also can move on the external above-below direction, can be free to advance or retreat with respect to flow export 39.When scavenging pump 26 work, valve body 41 rises under the pressure effect of the washings that flow into from inflow entrance 38, near flow export 39.Drive motors 54 rotates valve body 41, and will have washings to supply with in the flow export 39 of peristome 42 position consistency, and will have in the cleaning device 27 that this flow export 39 is communicated with that washings are injected to come out.

By valve body 41 is rotated, can switch the flow export 39 that has washings to supply with successively, and the cleaning device 27 of jet cleaning water is switched with the order of 27a, 27b, 27c, 27d.At this moment, the driving method of drive motors 54 has the Continuous Drive method, make interrupted driving method that peristome 42 stops on the position of flow export 39 etc., but also is not limited to these two kinds.

In addition, before employing, under a kind of occasion of method, need not detect the parts such as sensor of the position of valve body 41, relatively simple for structure; Under the occasion of a kind of method after the employing, though need devices such as position sensor, the switching efficiency height can according to circumstances be set the position and the injecting time of cleaning device 27 selectively.

Under the effect of said apparatus, washings need not be supplied with 4 place's cleaning devices 27 simultaneously, but supply with washings successively, thus output is increased, can be for arbitrary thing 23 that is cleaned from a plurality of direction jet cleaning water.Therefore, can wash at short notice attached to tableware etc. and be cleaned fouling product on the thing 23, realize high efficiency cleaning.

In addition, because the washing agent and the leftovers that are cleaned on the thing 23 attached to tableware etc. just can rinse well at short notice, so can reduce washing time.For example, can be be reduced to 3 times of carrying out 4 times originally.Output each time can not increase yet, and because number of times has been cut down, the time of heating with 30 pairs of washings of heater also can shorten, thereby can reach the effect of province's energy, water-saving.

In addition, owing to be the quantity that under the prerequisite that does not increase inflow, has increased washer jet 27, be cleaned the cleaning way of thing 23 from a plurality of direction jet cleaning water thereby can adopt with respect to tableware etc.Like this, the user will be cleaned the position that need not consider when thing 23 is put into tableware basket 24 to place, vertically put, mode such as traverse, can freely lay, can obtain laying property dish cleaning machine more excellently.Even for the tableware that the little bowl of square, darker little bowl, square plate etc. can not clean up fully by the jet cleaning water of single direction, also can bring into play cleaning performance fully.

In addition, can about several seconds to 1 minute, switch from time that the cleaning device 27 in a place sprays, can carry out high efficiency cleaning like this.Allow all cleaning devices 27 carry out 1 injection at least but preferably in per 1 time cleaning or flushing process, set.Therefore, above-mentioned injecting time can be set at about 10 seconds to 30 seconds.

Because valve body 41 is driven by drive motors (motorized motions source) 54, thus valve body 41 is rotated, thus switch the cleaning device 27 of supplying with washings reliably.

In addition, as shown in Figure 5, valve body 41 can also move, and leaves from the face A that is provided with flow export 39.That is to say that valve body 41 can move down, even when scavenging pump 26 work, also can carry out such moving.Because foreign matters 49 such as leftovers and toothpick can be mixed in circulation together in the washings, as shown in Figure 6, when because of the rotation of peristome 42 and the gap between the flow export 39 more and more hour, foreign matter 49 just in time can sandwich wherein sometimes.If valve body 41 does not separate with flow export 39, the foreign matter 49 of some kind can make valve body 41 stuck, causes and can not switch.Under the very strong situation of the driving force of drive motors 54, also may cause valve body 41 and flow export 39 to damage.

Therefore, in the utility model, valve body 41 is owing to be configured to separate with the face A that is provided with flow export 39, can resemble mobile shown in Fig. 7, so can avoid foreign matter 49 to snap in, can make rotating drive unaffected.When foreign matter 49 snapped in, all cleaning devices 27 all had washings to supply with, but the supply of the washings of this moment is insufficient, when on the position that forwards next flow export 39 to, foreign matter 49 is washed out, and switches thereby can normally carry out washings once more, cleans efficiently and is cleaned thing.

In addition, foreign matter 49 can be various things, also may be fish-bone, toothpick, elastic tape, plastic paper or tableware fragmentation or the like except food.The elongated article such as stem of toothpick and cherry particularly are no matter its length how, owing to may pass the leftovers filter screen, so the countermeasure that also will be necessary for such foreign matter.

The above-mentioned foreign matter that those block 49 generally can be disposed, but the not situation of easy-clear of elongated foreign matter is also arranged after turning over one or several flow exports 39.For this reason, when scavenging pump 26 was stopped midway temporarily, valve body 41 separated with flow export 39 under its deadweight effect when stopping, and the foreign matter 49 that blocks is disposed.Like this, just foreign matter 49 can not take place snaps in the situation that causes valve body 41 not rotate in the gap, thereby can carry out the switching of valve body 41 reliably.

Because scavenging pump 26 is cleaning and rinsing step stops when finishing to I haven't seen you for ages, for once cleaning exists because of switching the bad possibility that causes cleaning performance to descend, but from next time use, just uses and do not have problem.In addition, cleaning and the scavenging pump 26 that midway makes of rinsing step stops several times temporarily, can be suppressed to Min. with switching bad number of times, thereby can suppress the decline of cleaning performance.

In addition, as shown in Figure 7, valve body 41 is that above-below direction can tilt with respect to its straight-line direction.Observe from the top when being the running part of the valve body 41 in cross section and motor shaft 55, can see with motor shaft 55, between motor shaft 55 and the valve body 41 as shown in Figure 8 be provided with gap 41a like that, on all directions, can tilt.

So, valve body 41 also can successfully move under the situation that has foreign matter 49 to block.In addition, on the end face of flow export 39 and the contact portion of peristome 42, can carry out processing such as chamfering, fillet, the lock out operation of valve body 41 is more successfully carried out.

In addition, even in the part gap of flow export 39 and valve body 41, have foreign matter 49 to block, because under the occasion that acts on the power that has been applied with on the valve body 41 of the pressure of washings etc., can prevent that also valve body 41 is stuck in valve casing 40 grades, makes the generation of the situation that valve body 41 can not switch as lever.

So, valve body 41 and valve casing 40 angle of inclination that can not be damaged can be set at the bigger angle in angle of inclination that can be inclined to when blocking with the onesize foreign matter 49 in the gap of leftovers filter screen 29.In addition, the binding between valve body 41 and the motor shaft 55 can be adopted universal joint, also can play same effect with similar mode certainly.

In addition, scavenging pump 26 is started working moment valve casing 40 and valve body 41 between have under the situation that foreign matter 49 blocks, all cleaning devices 27 all will be supplied to washings, the supply of washings may be insufficient, but when scavenging pump 26 stops temporarily, the distance between flow export 39 and the valve body 41 will become greatly, and foreign matter 49 will be removed, just can switch without a doubt when scavenging pump 26 is started working once more, thereby can clean up being cleaned thing 23 expeditiously.

In addition, as shown in Figure 9, when scavenging pump 26 quits work, separate with flow export 39, elastic force bringing device 50 can also be set, be applied with elastic force from flow export 39 detaching directions at valve body 41 in order to make valve body 41.Having between valve casing 40 and the valve body 41 that foreign matter 49 snaps in, under the scavenging pump 26 out-of-work states, can prevent the generation of the situation that valve body 41 can not separate with flow export 39, thereby can under the state of quitting work, reliably foreign matter 49 be removed like this.

After adopting said structure, no matter what direction valve body 41 is arranged on, can separate with flow export 39, can be arranged on advantage on any angle (direction) thereby have division box 37.In addition, elastic force bringing device 50 can also use elastomers such as leaf spring, rubber except illustrated ring spring.

In addition, under scavenging pump 26 duties, valve body 41 is by promptly pressurized upward to flow export 39 1 sides under the pressure effect in valve casing 40, tight exposure level between the sealing surface of valve body 41 and flow export 39 is enhanced, the leakage of washings can greatly reduce, more washings are ejected from cleaning device 27, and cleaning performance can be further enhanced.If valve body 41 and flow export 39 can be out of shape under the hydraulic pressure effect, then above-mentioned sealing property can be further enhanced.

In addition,, be pressurized to about 20～40kPa usually in the valve casing 40,, be roughly about 20～100N usually though the power that acts on valve body 41 varies in size obstructedly because of it at scavenging pump 26 duration of works, thus with it securely by being pressed on the flow export 39.

On the other hand, under the state of valve body 41 by the washings pressurization, valve body 41 will produce very big friction when rotating, and valve body 41 and flow export 39 have the danger that is worn.By when drive motors 54 is worked, scavenging pump 26 being quit work, can address this problem.When scavenging pump 26 stops, driving valve body 41 and rotate,, drive motors 54 is quit work and allow scavenging pump 26 task again until arriving next assigned position.Like this, 41 of valve bodies can abut against on the flow export 39, can not slide, and therefore produce abrasion hardly.

Like this, the life-span of division box 37 and reliability can be improved.In addition, even scavenging pump 26 and drive motors 54 are worked simultaneously at part-time, only otherwise cause abrasion, just there is no need to allow scavenging pump 26 stop fully.

In addition, though wish to fit tightly between flow export 39 and the valve body 41, even but exist because of the reasons such as dimensional accuracy of parts cause trickle gap, perhaps the pettiness gap is set under the occasion below the 1mm, though have some to leak a little to other flow exports 39, division box 37 can be crossed and play the branch water function fully.

In addition, the distance that valve body 41 leaves flow export 39 is more than the gap in the leftovers filter screen 29, between flow export 39 and valve body 41, can form like this than passing the big gap of size that leftovers filter screen 29 flows into the foreign matter 49 in the division box 37, so during scavenging pump 26 quits work, the foreign matter 49 that is stuck in wherein can be removed, thereby the division box 37 that always can keep high reliability can be provided.

In addition, the gap in above-mentioned " more than the gap of leftovers filter screen 29 " is meant and is equivalent to Circularhole diameter, mesh length of side equidimension.Strictly speaking, be more than the minimum dimension B of as shown in Figure 10 the foreign matter that may pass leftovers filter screen 29 49.In addition, leftovers filter screen 29 comprises the fixedly filter screen 51 that is fixed under non-disconnectable on the discharge outlet 28 sometimes and can pull down detachable filter screen 52 these 2 filter screens that clean.As long as set, just do not have problem when working usually according to the little side's in its intermediate gap size (normally detachable filter screen 52).But, owing to exist detachable filter screen 52 wrong or forget the installation equally likely possibility, set for much larger than the words of the fixing distance in the gap of filter screen 51 reliable by dress.

In addition, the minimum clearance between valve casing 40 and the valve body 41 is set greater than the gap that is described leftovers filter screen 29.Gap between valve casing 40 and the valve body 41 is meant the excircle of valve body 41 and the end face air line distance to valve casing 40.In addition, the above meaning in the gap of leftovers filter screen 29 is with top identical.So, owing to the big gap of size that between flow export 39 and valve body 41, exists than the foreign matter 49 that may flow into division box 37, so can prevent the situation generation that foreign matter 49 snaps in these gaps, causes valve body 41 not switch.

In addition, use cleaning device 27 to be supplied to the checkout gear (not shown) that washings detect, can also change the injecting time of each cleaning device 27, carry out more high efficiency cleaning which.For instance, in order to improve the cleansing power for the difficult rice bowl of washing, it is very resultful will being arranged to more longer than other setup times from the injecting time of cleaning device 27a.

Checkout gear can comprise that device, the pressure in the detection purge path 43 or the device that has or not of flowing water etc. of the turned position of detecting valve body 41 are good multiple.In addition, there is no need upper sensor to be set in 4 places.As long as upper sensor is set, in conjunction with information such as the work of scavenging pump 26/stop, rotating speeds, just can knows and eject washings again from which position in 1 place.

In addition, there is no need under the occasion of all cleaning devices 27 jet cleaning water in the less grade of the amount that is cleaned thing 23, the injecting time of unnecessary cleaning device 27 can be set at the utmost point short time below 1 second, they are sprayed hardly, and only allow necessary cleaning device 27 spray.Like this, can clean with higher efficient, in the hope of shortening working hours.In addition, undertaken by the cleaning device 27c that is located at tableware basket 24 tops, can reduce as much as possible, further improve cleaning performance attached to the fine water droplets that is cleaned on the thing by making the final injection in the flushing process.

In addition, in the present embodiment, be provided with cleaning device 27, and all be rotary rotary nozzle in 4 places.But, also can not be defined as 4 places, also can dispose the number of setting cleaning device 27 according to the tableware in the tableware basket 24.Though, consider for all tablewares and can both receive that 2 injections more than the direction are very important this facts for improving cleaning performance, preferably are arranged to more than 4 places as long as more than 2 places, just can bring into play effect.

When dividing way too many conversely speaking,, the Total Water that ejects from 1 cleaning device 27 can reduce, and cleaning performance on the contrary can be not good.Therefore, preferably be arranged on 10 and sentence down, particularly 6 sentence down.

In addition, use the words of rotary nozzle can improve cleaning performance really in the cleaning device, but also exist the problem that the volume of accommodating the part that is cleaned thing 23 under the situation that cleaning device 27 shared spaces increase, the outer cage of main body is measure-alike can reduce.Therefore, as shown in Figure 11, it is the effective way that can address the above problem that the washer jet that is arranged on the back side and top is selected the fixed cleaning device 27c, the 27d that do not rotate for use.The set-up mode of rotary nozzle here and fixed nozzle etc. and the number of jet thereof are not restrictive regulations.

In addition, can also set best cleaning device 27, cleaning performance is further enhanced according to the shape of dish cleaning machine main body 20 and tableware configuration etc.For example, can resemble Figure 12 at 27a, 27b, configuration cleaning device 27 in 3 places such as 27e perhaps as Figure 13, is divided into 2 layers up and down with tableware basket 24,2 rotary nozzle 27c is set, 27d etc. on the mid portion of the basket 24 of levels.

In addition, though the cleaning device 27 that at a time sprays in a plurality of cleaning devices 27 in the superincumbent description has only 1 place, but also can a plurality of cleaning devices 27 be sprayed simultaneously, its position is switched also be fine by 2 places or more peristome 42 are set on valve body 41.

In addition, 1 in a plurality of flow exports 39 is connected with the drain passageway of discharging washings outside machine, can just can carries out draining without draining pump 32.So just there is no need to be provided with draining pump 32, can reduce cost, make equipment miniaturization.

In addition, when switching cleaning device 27 successively in cleaning process, washings also are certain to flow to that above-mentioned flow export 39, will drain as long as scavenging pump 26 constantly is operated in the cleaning process water like this.For this reason, can just be supplied to which flow export 39 to washings and detect, the flow export of not using to draining in the time beyond the draining 39 is supplied with washings, can prevent the time draining outside machine beyond draining like this.In addition, by open and close valve is set, can prevent reliably that washings from being arranged outside machine on drainage channel.

In addition, the utility model is the utility model of the switching mode of relevant washings, and the thing of configuration, each configuration of components etc. be cleaned to(for) the switching mode of the shape of dish cleaning machine main body 20 and size, door 21, tableware etc. all not have requirement/qualification especially.In addition, shown in the present embodiment is the dish cleaning machine with functions/drying, also can reach same effect for the dish cleaning machine that does not possess functions/drying.

(embodiment 2)

The structure of the division box 37 in the present embodiment such as Figure 14, shown in Figure 15 are made of valve casing 40 that is provided with inflow entrance 38 and 4 flow exports 39 and transportable valve body 41 with the same among the embodiment 1.Valve body 41 is provided with the peristome 42 that allows washings pass through.But saved the drive motors 54 that drives valve body 41.Parts instead are respectively arranged with in valve casing 40 1 sides and valve body 41 1 sides and valve body 41 are rotated make valve body 41 rotate one group of bottom meshing part 45 of predetermined angulars when one group of top meshing part 44 of predetermined angulars and valve body 41 descend.

As shown in Figure 14, valve casing 40 is slightly cylindrical, and its axis direction general arrangement is on vertical direction, and the inflow entrance 38 that flows into for the washings through scavenging pump 26 pressurizations is arranged on valve casing 40 lower ends, and flow export 39 is arranged on the upper surface of valve casing 40.Valve body 41 slightly is flat shape, and flow export 39 places and valve body 41 relative face A also are flat shape.

When scavenging pump 26 work, current (pressure) effect of the washings that flow into from inflow entrance 38 down valve body 41 have the upwards rise of action of rotation with rectilinear motion roughly along the slope on the top meshing part 44, as shown in Figure 15, on the assigned position that flow export 39 is opened, be fixed, will have washings to eject from the cleaning device 27 that is connected with this flow export 39.Top meshing part 44 (does not illustrate the detailed structure of meshing part in the sectional view, with reference to Figure 18) be configured to like this, when promptly observing under valve body 41, the locational peristome 42 that allows washings flow through that is located on the valve body 41 is aligned with each other with above-mentioned flow export 39 such position as shown in Figure 16.

Next, when scavenging pump 26 is quit work temporarily, make progress from the below pressure of jack-up of valve body 41 is no longer worked, valve body 41 its deadweight effect again falls down.But this moment, valve body 41 was that inclined plane on bottom, the edge meshing part 45 is rotated on one side and fallen, and stopped at last on the assigned position shown in Figure 17.

When scavenging pump 26 was worked once more, valve body 41 meshed with the next inclined plane of top meshing part 44, rises while rotating, and is connected with next flow export 39, makes next cleaning device 27 eject washings.Like this, work intermittently, the cleaning device 27 of jet cleaning water is switched with the order of 27a, 27b, 27c, 27d, can play and identical with embodiment 1 reach very high cleaning performance by division box 37 by making scavenging pump 26.

The top meshing part 44 and the bottom meshing part 45 of circle are expressed its relation behind planar stretch words, as shown in Figure 18, the continuous repetition of the work by scavenging pump 26/stop, valve body 41 is carrying out the roughly rectilinear motion of above-below direction and the combination action of rotational motion on one side, Yi Bian carry out evolution successively.In addition, in the present embodiment,, spend through valve body 41 rotations 90 that stop/working again once for the flow export 39 that makes 4 places switches successively.As shown in Figure 18, top meshing part 44 and bottom meshing part 45 are configured to, and valve body rotates about 20 degree when rising, and rotate about 70 degree during decline.

In addition, the shape of these meshing parts also is not limited to shapes such as spirality and triangle, as long as make the flow export 39 of regulation and the peristome 42 of valve body 41 align just passable when scavenging pump 26 is worked intermittently.For example, do not make leg-of-mutton claw shape, be fine yet but make the mobile structure in groove 46 of the sort of deflector roll 47 shown in Figure 19.In addition, the position of meshing part also is not limited to the periphery of valve body 41.

Like this, the switching of the cleaning device 27 of jet cleaning water just can realize that electric driving mechanisms such as 3 logical valves and motor just can save, thereby can reduce cost, and make division box 37 realize miniaturization by the interrupter duty of scavenging pump 26.In addition, under motor-driven occasion, be provided with, careful sealing device need be set, make structure complicated because turning cylinder need connect valve casing 40.Simultaneously, also might leak during poor sealing to the goods outside.And do not have the parts that connect valve casing 40 work in the formation of the present utility model, do not worry leaking to the outside.

In addition, under the state when scavenging pump 26 work, be pushed under the pressure effect of valve body 41 in valve casing 40 above flow export 39 1 sides promptly are pushed to.So, because the close applying degree of the sealing surface of valve body 41 and flow export 39 is enhanced, the leakage of washings can reduce to extremely small degree, thereby can eject more washings by cleaning device 27, further improves cleaning performance.If valve body 41 or flow export 39 can be out of shape under the hydraulic pressure effect, then above-mentioned sealing can further improve.

In addition, in the present embodiment, the vertical motion of valve body 41 realizes that by the pressure of the washings after pressurized down maneuver is carried out under the deadweight effect of valve body 41, and the axis direction of valve body 41 need be arranged on roughly on the vertical direction.In this case, the proportion of valve body 41 need be more than 1, and the scope that valve body 41 can rise during pressurization is big more, descends and rotational action with regard to finishing reliably more, and the performance of handoffs of division box 37 is also just high more.Even valve body 41 is made of resin material, also can finish change action fully.But be to use the heavier material of proportion with metal etc. or make up with resin material and metal material, more effective.In addition, produce the elastic force bringing device that the spring of thrust or elastomeric material etc. constitute, valve body 41 is moved by using on valve body 41 towards flow export 39 detaching directions.Under such occasion, division box 37 just there is no need necessarily to be arranged on the vertical direction, but can be arranged on arbitrarily on the direction.

At top meshing part 44 places, valve body 41 is that slide in pressurized one side on one side, and meshing part 45 place's hydraulic pressure in bottom are then inoperative.Therefore, diminish, can reduce the abrasion of top meshing part 44, prevent that the position of peristome 42 and flow export 39 is inconsistent etc. and cause the generation of switching phenomenon such as bad by rotational angle with top meshing part 44.And, can make and withstand flow export 39 from the valve body 41 of starting working of scavenging pump 26 and can shorten for extremely time, the probability that foreign matter 49 snaps in can reduce, and cleaning efficiency can improve.

On the contrary, though do not illustrate among the figure, rotational angle hour during work when valve body 41 was finished rotational action when rotational angle was set than scavenging pump 26 work during stopping when valve body 41 was finished rotational action when scavenging pump 26 stopped, the rotational angle of valve body 41 will diminish when scavenging pump 26 stops, the traveling time of valve body 41 also will shorten, the dwell time of scavenging pump 26 also can shorten, and the working time of scavenging pump 26 can prolong, and cleaning efficiency can improve.

In addition, by configuration top meshing part 44 and bottom meshing part 45, when rotational angle was roughly the same during work when valve body 41 is finished rotational action when rotational angle and scavenging pump 26 work when making stopping when valve body 41 was finished rotational action when scavenging pump 26 stopped, the meshing part inclined degree of the rotational angle when determining to rise and the descend inclined degree H of inclined degree G and the decline side of uplifted side as shown in figure 20 was 45 maximums of spending.Like this, can realize not having the reliable operation of misoperation on the both direction.

In addition, as shown in Figure 14～Figure 17, top meshing part 44 and bottom meshing part 45 also can be located at the inboard of flow export 39 (peristome 42).The inboard is slower than the peripheral speed of the excircle of valve body 41 during rotation, and displacement is also little, and the angle on the inclined-plane of meshing part is also steeper, and the rotational action of valve body 41 is also more stable.Simultaneously, the wearing and tearing of top meshing part 44 and bottom meshing part 45 also can reduce, and can reduce to produce to switch bad probability.

In addition, in top meshing part 44 1 sides, valve body 41 is to be roughly rectilinear motion what will carry out with valve body 41 before flow export 39 contacts during scavenging pump 26 work.That is, under the effect of the jut F on the top meshing part 44 as shown in Figure 18, make roughly rectilinear motion upward.Therefore, under pressurized washings effect and the valve body 41 that moves does not carry out rotational action and rises, withstand with flow export 39, valve body 41 can not withstand flow export 39 while rotating, on both contact-making surfaces, wear and tear hardly, thereby the diameter in capable of reducing using can not produce the phenomenon that causes performance of handoffs and strength of parts geometric ratio A-stage deterioration because of wearing and tearing with the variation that takes place service time.Like this, just there is no need to use high-abrasive material, only use resin-molded components such as general PP and POM just passable.

In addition, two sides in valve body 41 and flow export 39 contact portions or either party are formed with rubber and elastoplast elastomeric material, the adherence between valve body 41 and the flow export 39 will have tremendous raising.But, need under the occasion of slip at valve body 41 and flow export 39, then can not use because frictional resistance is big.In present embodiment, make valve body 41 with do before flow export 39 contacts to use in the roughly straight-line structure, the wearing and tearing of elastic materials will reduce, thereby can go out better effect.

In addition, use and detect the checkout gear (not shown) that washings just are being supplied to which cleaning device 27, the injecting time of each cleaning device 27 can change, thereby can carry out the higher cleaning of efficient.For example, want to improve the cleaning force for difficult cleaning things of washing such as rice bowls, it is effectively being arranged to the injecting time of cleaning device 27a than other cleaning device length.

Checkout gear can have the turned position of detecting valve body 41 device, detect the various modes such as device of having or not of pressure in the purge path 43, flowing water etc.In addition, there is no need,, in conjunction with information such as the work of scavenging pump 26/stop, rotating speeds, just can know again from which position injection even only sensor is set at 1 place at 4 local sensors that use.

In addition, less in the amount that is cleaned thing 23, there is no need under the occasion of whole cleaning device 27 jet cleaning water, the injecting time of unnecessary cleaning device 27 can be arranged to the utmost point short time of 1 second following degree, make it to spray hardly, and only allow necessary cleaning device 27 spray.Like this, can clean with higher efficient, the operating time also can shorten.

In addition,, can reduce as far as possible, further improve cleaning performance attached to the fine water droplets of cleaning on the thing by the final injection of rinse stage is arranged to be undertaken by the cleaning device 27c that is positioned at tableware basket 24 tops.

In addition, make and be provided with flow export 39 and certain inclination arranged with roughly linear movement direction (that is above-below direction) that valve body 41 facing surfaces A are done with respect to valve body 41.As shown in Figure 15, the opposite face that flow export 39 and valve body are 41 is a horizontal direction, is equivalent to linear movement direction inclination 90 degree from valve body 41.So, be rectilinear motion because valve body 41 carries out when switching, have the effect that the distance with the opposite face A between flow export 39 and the valve body 41 widens.Washings circulate together even if foreign matter such as leftovers and toothpick 49 is mixed in, foreign matter 49 snaps in valve casing 40 and valve body 41 between the gap in, scavenging pump 26 stops, when valve body 41 leaves, foreign matter 49 also can be disposed from the gap.Can avoid division box 37 to be blocked like this, can reach similarly to Example 1 effect and effect, valve body 41 can be switched reliably by foreign matter 49.

In addition, the sort of scavenging pump 26 shown in Figure 21 is started working moment valve casing 40 and valve body 41 between have under the occasion that foreign matter 49 blocks, all cleaning devices 27 all will be supplied to washings, but the supply of washings might be inadequate.In case scavenging pump 26 stops, the distance of flow export 39 and valve body 41 will widen, and foreign matter 49 just can be got and remove, and the switching that just can be well on during scavenging pump 26 work next time cleans up thereby can will clean thing 23 with very high efficient.

In addition, even if under the situation that foreign matter 49 does not come off under the halted state of scavenging pump 26, foreign matter 49 can be rushed at flow export 39 1 sides under the flow action when scavenging pump 26 is started working, and can not continue to be stuck in the gap.In addition, remove,, foreign matter 49 is got removed through repeatedly stopping repeatedly/course of work again if scavenging pump 26 stops/working that through 1 time foreign matter 49 is got.In addition, if the shape of valve body 41 has some inclinations for upper surface, foreign matter 49 is just easier eliminating also.

In addition, as shown in Figure 16, the minimum clearance J between valve casing 40 and the valve body 41 is set at the gap greater than described leftovers filter screen 29.Gap between valve casing 40 and the valve body 41 is the outer rim of valve body 41 or the air line distance of tip to face distance valve casing 40.So, owing to exist than the big gap of size that may flow into the foreign matter 49 on the division box 37 between flow export 39 and the valve body 41, thereby can prevent that its foreign matter 49 is stuck in this gap, the situation that causes valve body 41 not switch occurs.

In addition, though top valve body 41 is a flat shape, this is not determinate regulation, even make taper shape or spheroid, can withstand flow export 39 and get final product under the hydraulic pressure effect.

In addition, as shown in Figure 15, each flow export 39 is configured to tubulose, and is outstanding in valve casing 40.So, the contact area of flow export 39 and valve body 41 is the end area of 4 pipes, and is much smaller when outstanding, also just is not easy to snap in foreign matter 49 between flow export 39 and the valve body 41, switches bad number of times thereby reduce.But such structure neither be determinate, as long as the shape of flow export 39 and valve body 41 is suitable, also can reach same effect even do not give prominence to.

In addition, scavenging pump 26 is constantly to repeat work and the process that stops among the top embodiment, but uses inverter motor at scavenging pump 26, make under the occasion that the output of pump can change, and also can utilize the output power of pump to come switching valve 41.Output during with " weak " just can be finished switching below being set at the output that valve body 41 can separate from flow export 39, the work of pump and stop number of times and just can reduce.Like this, the life-span of motor can prolong, and also can realize quietization during work.

In addition, be to be located at axle 60 on the valve casing 40 to insert structures in the hole 61 be located on the valve body 41 shown in Figure 15.The axle 60 and hole 61 between very near or contact with each other the rectilinear motion up and down and the rotational action of limiting valve body 41.For instance, the external diameter of valve body 41 is 100mm, and the diameter of axial region 61 is 5mm, compares with the occasion of carrying out relative motion on the excircle part of valve body 41, relative area (circumference) has only very little by about 1/20th, and the probability that snaps in foreign matter also becomes much smaller.Add, even snap in the words of foreign matter in the gap, as long as the resistance that is resisting foreign matter rotates required power (torque) equally also about 1/20th, change just can make valve body 41 move by the current in the valve casing 40 to need not the special driving device, make valve body 41 rotate required power and also diminished, foreign matter blocks the possibility that valve body 41 makes it to rotate and has just existed hardly.Like this, the phenomenon that can prevent that foreign matter from causing that division box 37 can not switch, all can not clean in the rinse bath 22 takes place, thereby can improve the high cleaning device of reliability.

As shown in figure 14, the center line K that flows into the inflow entrance 38 in the valve casing 40 for washings compared with the center of rotation L of valve body 41 come will be to excircle one lateral deviation from one apart from M, the eddy current generation of rotation valve casing 40 in will be arranged in the valve casing 40, and most, the proportion that accounts in the foreign matter is being pushed under the centrifugal action of this eddy current near the circumference of valve casing 40 than the big foreign matter of water.Like this, foreign matter has away from the axle 60 and the tendency in hole 61 near the center that is positioned at valve casing 40, and the probability that foreign matter snaps between the gap in axle 60 and hole 61 just can further reduce.

Valve body 41 be moved upward be washings pressure in action.Owing to be pressurized to about 20～40kPa usually in the valve casing 40, though act on the valve body 41 different because of the size of valve body 41, generally also between 20～100N,, also can make valve body 41 motions even more or less foreign matter blocks.But, when valve body 41 descends, the deadweight of then having only valve body 41 in action, its motive force is less.

Therefore, as shown in figure 22,, withstand valve body 41,, improve the reliability of switching even just can valve body 41 be moved with ring spring by being provided with the elastic force bringing device 62 of valve body 41 from flow export 39 separation.In addition, except the ring spring shown in Figure 22, can also use elastomers such as other forms of spring, rubber such as leaf spring, perhaps metal annex is fixed on the valve body 41 or insert and be formed into the deadweight that wherein increases valve body 41, also can reach same effect.In addition, magnet or magnetic are set on valve body 41, the structure of utilizing magnetic force to push valve body 41 to below also can adopt.

In addition, the shape in axle 60 and hole 61 also can be not limited to the shape shown in Figure 15, resemble axle 60 the cut shape in centre, the hole 61 shown in Figure 24 shown in Figure 23 do not connect the shape that forms closed pore, and valve casing 40 shown in Figure 25 on establish various schemes such as establishing axle 60 on hole 61, the valve body 41 and all can adopt, they can prevent reliably that foreign matter from snapping in.

Shown in Figure 26～Figure 28 the opposite face of flow export 39 and valve body 41 be situation beyond the flat shape.

Shown in Figure 26 is the opposite face of flow export 39 and valve body 41 situation when being cone shape.As shown in the figure, opposite face is from some inclination of level, and when valve body 41 separated with flow export 39 like this, the possibility that the foreign matter 49 that snaps in rests on the valve body 41 just can reduce, thereby a kind of higher division box 37 of function of removing foreign matter 49 can be provided.In addition, the direction of turning cylinder can produce good effect no matter be provided with on what direction all from the horizontal direction run-off the straight.

In addition, even under flow export 39 and valve body 41 state of contact, valve body 41 also can rotate, and the path of washings just switches the rectilinear motion range-independence with valve body 41, can improve the free degree when designing.In addition, adopting as shown in the figure washings that flow out from flow export 39 to contain under the occasion of structure of oriented horizontal direction bending, conical flow export 39 contains the composition on normal (level) direction, divides the pressure loss of water portion also can reduce.In addition, the distance that valve body 41 separates is the distance between face and the face, and the size C among the figure is this distance.

In addition, there is no particular limitation for the cone angle D of conus portion.But will become impossible owing to carve moving of type thing effect valve body 41 when spending near 0, in order to ensure the gap of necessity, straight-line distance is with elongated, and valve casing 40 also has the problem that becomes big.So the cone angle D of conus portion will be preferably in more than 90 degree more than 30 degree.

Situation when in addition, the opposite face that flow export 39 and valve body 41 be shown among Figure 27 is pyramid shape.Because opposite face is also from horizontal tilt, so can play the effect same with circular cone, and, opposite face between flow export 39 and the valve body 41 is roughly the plane, flatness by opposite face and angle just can management component shape, even if under the occasion of producing in batches, use the parts of given size, just can produce leak less, the division box 37 of stable performance.

Situation when showing opposite face between flow export 39 and the valve body 41 in addition, among Figure 28 and being spherical.Under some relative with flow export 39 obliquely occasion of valve body 41, though understanding some, the position of peristome 42 and flow export 39 do not line up, but owing to be spherical as the flow export 39 and the valve body 41 of opposite face, therefore the gap between flow export 39 and the valve body 41 can not broaden, the leakage of washings can not enlarge, and can keep performance of handoffs.

Being shaped as of flow export 39 shown in Figure 29 is fan-shaped, and the peristome 42 of the valve body 41 shown in Figure 30 is the kerf that links with the profile portion of valve body 41, and essential structure and effect, effect are identical with embodiment 2.

Being shaped as of flow export 39 is fan-shaped, disposes a plurality of flow exports 39 around axle, and the shape E that these flow exports 39 form is roughly circle.Under the condition of the area of guaranteeing same flow export 39, such shape can make the profile of valve body 41 for minimum, can guarantee sufficient gap between valve body 41 and the valve casing 40, can prevent that foreign matter 49 from snapping in, and realizes the miniaturization of division box 37.

In addition, the profile of valve body 41 is roughly circular, just is difficult for sandwiching foreign matter 49 between valve body 41 and the valve casing 40, and the bad probability that switches also can reduce.And because the resistance of valve body 41 when moving can reduce, moving of valve body 41 can be more smooth, the time is also shorter, the 26 out-of-work times of scavenging pump shortened, thereby can carry out high efficiency cleaning in the shorter time.

By resemble shown in Figure 30 peristome 42 is made the kerf that the profile portion with valve body 41 is connected, even under foreign matter 49 will sandwich occasion between flow export 39, valve casing 40 and the peristome 42, foreign matter 49 also has the place that can avoid, thereby jammed probability can be reduced.

In addition, the top meshing part 44 of valve casing 40 1 sides and the mutual dual-purpose of next door part of flow export 38, and be arranged between the adjacent flow export 38.Like this, the inside and outside meshing part that do not exist of flow export can make the size (external diameter) of valve body become minimum under the prerequisite of guaranteeing identical outflow area, makes division box 37 realize miniaturization.

The structure that can decompose for division box 37 shown in Figure 31.This figure is the oblique view of the bottom of rinse bath 22, and by rotating and pulling down cap 53, division box 37 just can decompose.So, processing such as just can clean,, also can get attended operation, thereby can use switching under the state that can carry out reliably except that foreign matter 49 grades just in case situation takes place to switch etc. to the inside of division box 37.

Particularly, if adopt from the rinse bath 22 inner structures that just can decompose, need not take dish cleaning machine main body 20 apart and just can carry out upkeep operation, user oneself also can carry out upkeep operation, makes upkeep operation be very easy to carry out.

In addition, except making the said structure that cap 53 and screw become one, also can adopt structure, the cap 53 backing out screw and pull down again to insert the back and firmly grasp, click again the methods such as structure that just can pull down by claw.In addition, in rinse bath 22, do not decompose, but can simply decompose, can easily carry out upkeep operation yet from the bottom surface.

In addition, resemble that the aperture position of valve casing 40 is located in the rinse bath 22 present embodiment, rinse bath 22 and valve casing 40 just can constitute with parts.In this case, division box 37 danger of leaking has not just existed.

Figure 32 is the vertical view of valve body 41, is provided with at axle 60 outstanding below valve casing 40 and is trapped among the muscle shape protuberance 63 that direction of principal axis extends outside it, constitutes near parts.Identical among other basic comprisings and the embodiment 2.

With the same among the embodiment 2, when scavenging pump 26 constantly repeated the process of work/stop, valve body 41 moved up and down, and rotated 90 degree at every turn, switched the cleaning device 27 of jet cleaning water successively.Be located at 4 protuberances 63 of axle on 60 and play effect, during when axle 60 contacts or near hole 61, while valve body 41 rotates moving linearly near parts.Because near parts (lug boss) 63 with near forming between the parts (lug boss) 63 than its big spatial portion 63a, what have possibility that foreign matter snaps in has only on 4 points near portion, and foreign matter just more is difficult for snapping in like this.

As shown in figure 33, in case there is foreign matter 49 to sandwich, valve body 41 is as long as rotate slightly, and foreign matter just is easy to remove, and so just can avoid foreign matter to block the generation that valve body 41 makes it situation about can not switch.If top meshing part 44 is set for as shown in Figure 34, action (moving to oblique below as shown by arrows) just rotates when valve body 41 begins to move when the current of washings stop or reducing, then foreign matter 49 can resemble shown in Figure 35 to moving near portion's (lug boss) 63 with near the 63a of broad space portion between portion's (lug boss) 63, thereby can dispose reliably.

The adjacent gap near between the portion 63 is set at bigger, can avoids foreign matter to stop up more reliably than the mesh of leftovers filter screen 29 size.Usually, leftovers filter screen 29 is formed by the sheet metal that is installed with a large amount of apertures etc., as long as be set at big just more passable than its aperture (1mm to about 2mm).But under the occasion of detachable filter screen and fixed filter screen, preferably be set at the gap bigger than the size of fixed filter screen.

In addition, on the outer circumferential sides in axle 60 and hole 61 bottom meshing part 45 can also be set respectively.As shown in figure 36, in scavenging pump 26 work, have on valve body 41 positions under the state that washings pass through, lug boss 63 is configured to aim between the adjacent top 64 of the bottom meshing part 45 that is located at valve body 41 1 sides.Because meshing part 45 is the triangle shown in the figure, meshing part 45 and space exist again alternately, and foreign matter is along with the current in the valve casing 40 are very high from the possibility that space segment snaps between meshing part 45 and the axle 60.Top 64 is consistent with lug boss 63, snaps in possibility in its gap though increased foreign matter, by making the centre of lug boss 63 facing to the top 64 of adjacency, relative area reduced, and has reduced foreign matter and has snapped in possibility in the gap.

And, as shown in Figure 37,, make this recess 65 relative with lug boss 63 by the recess 65 that not have to tilt is set between the top 64 of adjacency and top 64, spools 60 and bottom meshing part 45 between snap in foreign matter situation just can avoid fully.In addition, under this occasion,, make the relation of all lug bosses 63 all have identical condition, can further improve for the stability of foreign matter if make the quantity of lug boss 63 consistent with the quantity at the top 64 of meshing part 45.

(embodiment 7)

Figure 38 is the vertical view of valve body 41, and valve casing 40 and valve body 41 are roughly slightly circular, and the peripheral part of valve body 41 is provided with a plurality of lug bosses (near parts) 63.

Under the effect that is located at the lug boss (near parts) 63 on valve body 41 excircles, contact with each other between valve body 41 and the valve casing 40 or approaching, constitute a kind of structure of limiting valve body 41 motions, be provided with than its more bulky space segment 63a near parts 63 with between near parts 63.Having only in the valve body 41 can be near valve casing 40 near parts 63 parts, and the area that foreign matter might block will reduce, and the reliability of antagonism foreign matter can improve.

In addition, with the same among the embodiment 6,,, can avoid foreign matter to block the generation that valve body 41 makes it situation about can not switch as long as valve body 41 rotates slightly and just is easy to get remove even if the foreign matter that snaps near in the parts 63 is arranged.And, when the current of washings stop or reducing, make when beginning to move, just the rotate words of action of valve body 41, even near having foreign matter to snap on the parts 63, foreign matter will be inevitably near parts 63 with near moving the broad space between the parts 63, thereby can dispose, in most of the cases can avoid causing the appearance of situation about can not switch because of foreign matter.

The adjacent gap near between the parts 63 is set for bigger, can be avoided foreign matter to snap in reliably than the size of leftovers filter screen 29.Usually leftovers filter screen 29 is made of perforated sheet etc., sets for than its aperture (1mm and 2mm degree) to get final product greatly.Under the occasion that is provided with detachable filter screen and fixed filter screen, preferably be set at the gap bigger than the size of fixed filter screen.

In addition, lug boss 63 is not provided in a side of valve body 41 1 sides and the words that are provided in a side of valve casing 40 1 sides also can obtain same effect.In addition, also be not limited to the such shape of lug boss 63 near parts, also can resemble Figure 39 valve body 41 made smart circular, with part shown in the alphabetical N in scheming near various shapes such as parts.

Adopt aforesaid words of the present utility model, even snap at foreign matter under the occasion in the gap between valve body and the valve body, this foreign matter also is easy to remove, and the cleaning device that has washings to supply with also can switch reliably.

In addition, can also provide a kind of and can prevent that foreign matter from snapping in, leaking less, the high division box of shunt efficient.
