ejection path

33,34 is opened on connector 12a as introducing

port

12b, 12c in the concentric inside and outside double-deck access structure of pivot 11.

Flow export

36a, 37a are communicated with introducing

port

12b, 12c with being connected of rotary supporting part 41 by connector 12a.And as Fig. 2, shown in Figure 6, introducing

port

12b, 12c are that the

ejection path

33,34 of the point symmetry configuration at center is communicated with becoming with the pivot 11 in the intersection region in ejection path 33,34.That is, two flow out 36,37 and two

ejections path

33,34, roads, by linking to each other with the concentric inside and outside double-deck path of the pivot 11 that rotates washer jet 12.

By this structure, rinse water can not produce around pivot 11 and pulse or turbulent flow from flowing out road 36 to the mobile of ejection path 33 and from flowing out road 37 to spraying flowing of path 34 when making score water, and is in the laminar condition of more stable approximate equality.This is owing to utilize the inside and outside double-deck access structure concentric with pivot 11, rinse water is sprayed equably around pivot 11, thereby can eliminate the rotation relation different with its position of rotation of rotating washer jet 12.

Consequently, rinse water is imported

ejection path

33,34 by approximate equality ground.In addition, rinse water by the

ejection path

33,34, and can not destroy the rotation washer jet 12 spin balancing be imported into.Therefore, it is indefinite that rotation washer jet 12 all can not produce vibration, pulses or rotate when just changeing and during counter-rotating, but stably be rotated, and the situation of cleaning performance reduction can not take place to make because of rotation, also can not rotate indefinite situation because of position of rotation.

In addition, can make also that the passage sections integration to 33, the 34 fens water in ejection path is not equal from the

outflow road

36,37 of inside and outside double-deck path.Like this, the flow and the flow velocity of the rinse water of supplying with to ejection path that rotation washer jet 12 is just being changeed and the ejection path that makes 12 counter-rotatings of rotation washer jet are equated.And, can make the just commentaries on classics and the roughly constant speed of reversing of rotation washer jet 12, thereby the injection of rinse water is pressed about equally.

In addition, the structure of non-rotating washer jet 13 is any in following three kinds.First kind be only have from the bottom surface 4a of rinse bath 4 near the link 13a that is connected of division box 14, the structure of the riser portions 13b that rises separately as shown in Figure 1.Second kind is to have the structure through the riser portions of not shown horizontal part from link 13a.The third is to have the structure of passing through the horizontal part 13c of riser portions 13b from link 13a as shown in Figure 1.

Next, mainly use Fig. 2 and Fig. 7, further describe the matched tube structure of the dish cleaning machine of embodiment of the present utility model.Fig. 7 is the interior aerial view of rinse bath of the dish cleaning machine of embodiment of the present utility model.Cleaning/draining pump 8, division box 14, rotary supporting part 41 and flow export 42 can be disposed in the cornerwise regional A at a pivot 11 with the bottom surface 4a that connects rinse bath 4 and a turning 43.Here, regional A be bottom surface 4a area roughly 1/4.

Clack box 133 and can be from being connected with cleaning/draining pump 8 than the 41 nearer positions of the rotary supporting part in the regional A between rotary supporting part 41 and cleaning/draining pump 8.And rotary supporting part 41 is connected with the connector 12a of rotation washer jet 12 and the link 13a of non-rotating washer jet 13 in regional A.Consequently, can supply with rinse water with short pipe arrangement and path-length to rotation washer jet 12 and non-rotating washer jet 13 from cleaning draining pump 8.

Therefore, when dish cleaning machine 100 of the present utility model can be simplified matched tube structure,, can realize miniaturization, lightweight and cost degradation because volume is little.In addition, driving, the driving that can improve cleaning/draining pump 8 stop to carry out the responsiveness that branch water switches, thereby help suppressing the pressure loss, improve cleaning efficiency, shorten scavenging period.

In addition, as shown in Figure 2, extend in the opposite direction mutually towards the

outflow road

36,37 of rotary supporting part 41 and towards the outflow road 38 of flow export 42 from clack box 133.

According to above-mentioned formation, existence is towards the

outflow road

36,37 of rotation washer jet 12 and the outflow road 38 of extending in the opposite direction as non-rotating washer jet 13, though it is a plurality of flowing out the road, by division box 14 is set, the also changeable flow direction flows out the rinse water on

road

36,37,38.

In addition, flow export 42 is near the amount of cleaning/draining pump 8 sides, and the configuration area of correspondingly feasible cleaning/draining pump 8, division box 14 and rotary supporting part 41 and flow export 42 is less than regional A.Therefore, clack box 133 is connected with cleaning/draining pump 8 is connected distance and further shortens, and among the wall 4b under the situation on the wall on 8 edges of cleanings/draining pump, connects apart from also being shortened around the horizontal part 13c of non-rotating washer jet 13 is arranged at least.In addition, the situation of two walls, three walls or four walls among the wall 4b and also can be tackled around horizontal part 13c extends to from the configuration of riser portions 13b under the situation of circumferential both sides branch.

In addition, as Fig. 1, shown in Figure 4, rotary supporting part 41 and the connector 12a that rotates washer jet 12, the position above the bottom surface 4a than rinse bath 4 leans on vertically connects.Thus, rotation washer jet 12 constitutes and can connect the top position of mouthful 12a at the bottom surface of rinse bath 4 4a, not be connected with rotary supporting part 41 by other from vertical direction with hindering.

In addition, the link of riser portions 13b and flow export 42 also vertical connection of position above leaning on than the bottom surface of rinse bath 4.Thus, non-rotating washer jet 13 also constitutes and also can connect end 13a in the top position of the bottom surface of rinse bath 4 4a, not be connected with flow export 42 intrusively by other from vertical direction.

Rotation washer jet 12 constitutes: can flow out

road

36,37 by controlling selected two by division box 14 according to the driving of cleaning/draining pump 8, its direction of rotation is switched between rotating and reverse.Can consider multiple concrete grammar, the rinse water that can be used to the jet 44 of spinning washer jet 12 is sprayed energy for this reason, makes 12 rotations of rotation washer jet by the reaction force that sprays.So just can make rotation washer jet 12 forward or reverse, therefore change the ejection pattern of rinse water greatly, can be easy to not have the cleaning at dead angle.

In addition, as shown in Figure 3, clack box 133 has the connector 133b that extends to cleaning/draining pump 8 sides.And, clack box 133 below the 4a of the bottom surface of rinse bath 4, be positioned at rotary supporting part 41 roughly cleaning/the draining pump 8 of opposition side be connected.Corresponding therewith, as shown in Figure 7, be provided with the 4j of the portion of heaving that heaves upward in the scope that is provided with along rear wall 4c of cleaning/draining pump 8.And, by will being provided with in the space 47 of cleaning/draining pump 8 below heaving the 4j of portion, thereby can prevent from around rinse bath 4, to produce idle space.Thus, also can suppress dish cleaning machine body 2 maximizes.

Next, the spool 32 to division box 14 describes.Fig. 8 A～Fig. 8 D is the key diagram of spool actuating mechanism of the dish cleaning machine of exploded representation embodiment of the present utility model.

Spool 32 is in the inflow portion 39 of clack box shown in Figure 3 133 and divide between a plurality of

outflows road

36,37,38 of water passage 48 rotation to move.Consequently, spool 32 will switch to the outflow road of carrying out branch water from the rinse water that inflow portion 39 flows into.Particularly, spool 32 is used to switch the

ejection path

33,34,35 via outflow road shown in Figure 4 36,37,38 ejections.

Thus, shown in Fig. 3 and Fig. 8 A, be formed with four

branch water opening

48b, 48c, 48d, 48e on the connector 48a of minute water passage 48, these

minutes water opening

48b, 48c, 48d, 48e are divided into impartial size around the pivot 46 of spool 32 by criss-cross rib 48f.And shown in Fig. 8 B, Fig. 8 D, spool 32 is formed with the 32a of water flowing portion that has excised around 1/4 scope of pivot 46.Here, divide water opening 48b～48e from clack box 133 three to minute water passage 48 in flow out

roads

48b, 48c to be communicated with, divide water opening 48d to be communicated with, divide water opening 48e to be communicated with outflow road 38 with outflow road 37 with outflow road 36.

In addition, as shown in Figure 3, spool 32 forms discoid, but winding places the axis of guide 60 of clack box 133 bottoms to rotate freely, and can separate along the vertical direction/contact with respect to the connector 48a of minute water passage 48 by moving up and down.And then, at spool 32 during,, among branch water opening 48b～48e any opened by rotation around the axis of guide 60 with connector 48a butt.

Spool 32 is corresponding to being moved by the driving of cleaning/draining pump 8, the height that drives the cleaning hydraulic pressure that stops to cause or having or not of rinse water, and at predetermined position of rotation and the connector 48a butt with a plurality of minutes water opening 48b～48e.Like this, all closing beyond the specific branch water opening in Jiang Fenshui opening 48b～48e and being communicated with specific this minute water opening by water flowing portion comes the branch water level of minute water to put, and between leaving connector 48a and the overstepping one's bounds water levels that do not carry out branch water that each minute water opening 48b～48e all opens wide being put, spool 32 moves up and down.Follow this spool 32 to put and the round action of overstepping one's bounds water level between putting at minute water level, spool 32 changes closes the position of rotation of branch water opening 48b～48e, thus make top jaw to 61 and lower cam to 62 alternately actions.

Particularly, lower cam is made of intermeshing notched

cam

62a, 62b 62, and

cam

62a, 62b both sides have at each 1/4 position of rotation all makes the stable guiding condition of spool 32.Top jaw constitutes the 61 lower end formed crosswise cam 61b that separate the rib 48f of branch water opening 48b～48e by mountain font cam 61a and being used to.

Spool 32 is put when being cleaned hydraulic pressure and pushing away from stable overstepping one's bounds water level 62 by lower cam, the inclined-plane of mountain font cam 61a begins butt from the half-way of crosswise cam 61b, divides water level to put and settle out thereby make spool 32 rotation less thaies 1/4 then arrive.Then, make spool 32 when a minute water level deposits by removing cleaning pressure, lower cam is meshing with each other in the half-way of tooth separately each other to 62 notched cam 62a, 62b.Lower cam has 62 makes spool 32 change rotation up to 1/4 remainder that changes and the function that settles out from above-mentioned cam to 61 less than 1/4.In addition, Fig. 8 C represents the axis of guide 60 and notched cam 62b.

Thus, move to the branch water level on spool 32 is each and put, all the stable position of rotation rotation less than 1/4 before move is changeed.And, spool 32 each in case on move to the postpone of branch water level and fall again, lower cam will change under next 1/4 position stability that changes 62 the position that is meshing with each other.

Consequently, open wide among a plurality of minutes water opening 48b～48e each successively.That is, repeat following action successively: from minute outflow road 36 of water opening 48b process rotation washer jet 12 33 fens water in ejection path to rotation washer jet 12; From minute outflow road 36 of water opening 48c process rotation washer jet 12 33 fens water in ejection path to rotation washer jet 12; Flow out road 37 to the 34 fens water in ejection path from a minute water opening 48d process; And from minute water opening 48e through flowing out road 38 to the 35 fens water in the ejection path of non-rotating washer jet 13.

Like this, move this simple repetitive operation, can carry out the selectivity of while or timesharing successively and divide water by the rotation of spool 32.And pressure and releasing pressure that the advance and retreat of spool 32 are used to the rinse water of self-cleaning/draining pump 8 carry out.In addition, it is to utilize drive oing side boldly and keeping out of the way side of spool 32 advance and retreat that the rotation of spool 32 is moved, by means of the top jaw with phase place to 61 and lower cam the guiding of 62 pairs of direction of rotation is carried out.

The driving time that the driving of carrying out containing cleaning/draining pump 8 at control device 31 stops to be made as under the situation of certain control, pass through to divide

water opening

48b, 48c from the rinse water of draining/scavenging pump 8, and repeat the ejection path 36 of twice supply rotation washer jet 12.Rotation washer jet 12 was just changeed for the time of cleaning, make swivel nozzle 12 counter-rotatings be respectively twice by the ejection path 35 of flowing out the non-rotating washer jet 13 of road 38 supplies for the time of cleaning from minute water opening 48e by minute ejection path 37 of water opening 48d supply rotation washer jet 12 for time of cleaning and rinse water with respect to rinse water.

Fig. 9 is the stereogram of the carrying state of expression employed tableware basket of dish cleaning machine of embodiment of the present utility model and tableware.In order the rinse water of spraying from rotation washer jet 12 to be easy to arrive the recess as the inboard of food container of tableware, and carry out as described below.Tableware basket 6 is designed to: be the boundary by pivot 11 and the straight line 71 vertical, tableware is placed on the inboard mutual opposed symmetry direction that makes tableware 72 with mutual opposed rear wall 4c, front walls 4f among the wall 4b around the rinse bath 4.In addition, optimal design injection conditions etc. make and can clean fully tableware 72 grades of distributing rationally when rotation washer jet 12 is just changeing.

That is, when rotation washer jet 12 is just changeing cleaning, can clean fully usually, but the capacity that needs the reply scavenging period to shorten, be cleaned thing increases, is cleaned the problems such as deviation of the configuration of thing.Therefore, can clean the auxiliary cleaning of just changeing, do not clean with washing thereby can with shorter time and have to leak by counter-rotating.

In addition, as shown in Figure 9, tableware basket 6 also can be designed to a side of the tableware 72 of the mutual opposed mode balanced configuration in inboard bigger sometimes, and opposite side is less.Tableware basket 6 front and back shown in Figure 1 are opposed mutually, and forwardly the tableware of the big and rear portion side of the tableware of side hour is formed with the space above the zone of configuration than small tableware, tableware basket 7 also can be set in this space thus, thereby effectively utilize in the rinse bath 4.

But, in the reasonable clean range of rotation washer jet 12, be difficult to sometimes the zone of tableware basket 7 is cleaned or very waste.Therefore, can non-rotating washer jet 13 be main to the cleaning in the zone of tableware basket 7, assist by horizontal part 13c and carry out.

By in the scope corresponding of riser portions 13b, jet 44 being set, can improve the miscellaneous function of cleaning with tableware basket 7.Thus, the 13c of preferred levels portion also prolongs to the sidewall 4e opposite with the sidewall 4d that is provided with riser portions 13b, also can further consider to front walls 4f to prolong.From the miscellaneous function of this kind cleaning, around preferably being arranged at, horizontal part 13c on the complete cycle of wall 4b, also can be different from the prolongation zone of horizontal part 13c, be provided with to circumferential both sides branch from riser portions 13b.In this case, if make to the height of the horizontal part 13c of both sides branch and prolong the path difference, then be easy to tackle differences that wide in the rinse bath 4 clean short transverse in the zone, each position on the in-plane and clean difference between the load.

Here, also can consider on the basis in the ejection path 35 of a non-rotating washer jet 13, to set up one again, thereby

ejection path

33,34,35 be added that extension carries out branch water in four ejection paths altogether by four branch water opening 48b～48e.In this case, under the driving control of cleaning/draining pump 8, can make to branch water time of the 33 fens water in ejection path of rotation washer jet 12, and to the ejection path 34 of rotation washer jet 12, divide the branch water time of water identical to the ejection path 35 of non-rotating washer jet 13 and to the ejection path of setting up.

But, can be according to the driving of cleaning/draining pump 8 control, utilize the difference of carrying out the

ejection path

33,34 of the rotation washer jet 12 that selectivity supplies with from division box 14, and the direction of rotation of rotation washer jet 12 is switched in rotating and reverse.At this moment, control device 31 can freely be controlled the driving of cleaning/draining pump 8, so that just changeing the time and reversing time becomes predetermined ratio.Therefore, if control device 31 can according to cleaning/draining pump 8 when just changeing and when counter-rotating driving time separately ratio control the time of just changeing of rotation washer jet 12 and the ratio of reversing time.Under the situation that cleaning performance does not change when rotating and reverse, also can be set at equal with just changeing time and reversing time.

Certainly, comprise the ratio that

sprays path

36,37,38 and the ejection path of setting up and comprise the branch water time of branch water opening 48b～48e corresponding and extension with them, can be when utilizing control device 31 to carry out the branch water management ratio of the driving time of cleaning/draining pump 8, freely set and control.

When the ratio of the time of just changeing of controlling rotation washer jet 12 and reversing time, also can on rotation washer jet 12, dispose rotation direction detecting devices.Thereby control device 31 can based on the rotation washer jet just change the time and during counter-rotating the output of direction of rotation monitoring device control, making is just changeing the time and reversing time becomes predetermined ratio.

In addition, also can have the flow detector that the flow of washing water of supplying with two

ejection paths

33,34 is detected.Control device 31 can based on rotation washer jet 12 just change the time and the output of the flow detector during counter-rotating control, making is just changeing the time and reversing time becomes predetermined ratio.

And, have the spool position checkout gear that the supply switching position of supplying with rinse water to two

ejection paths

33,34 via two

outflow roads

36,37 is detected by making spool 32, can also realize following control.That is, control device 31 also can based on rotation washer jet 12 just change the time and the output of the spool position checkout gear during counter-rotating control, making is just changeing the time and reversing time becomes predetermined ratio.

In addition, as shown in Figure 4, rotary supporting part 41 has the bending height zone H of crooked usefulness.Divide the

outflow road

36,37 of water passage 48 to have: promptly to stretch out path domain B with the horizontal path of stretching out of stretching out along the bottom surface 4a of rinse bath 4 from clack box 133; With from stretch out path domain B towards the rotation washer jet 12 pivot 11 direction bendings crooked route up be crooked route scope C.And the outer at least turning C1 side of crooked route scope C is a curved shape, as an example, forms the curved shape that radius of curvature does not have slyness jumpy.In addition, stretching out the path links to each other with crooked route.

Thus, divide water to the rinse water in the

outflow road

36,37 of dividing water passage 48 to pass through slick and sly crooked route scope C from stretching out path domain B.Then, rinse water is guided to flow export 36a, the 37a that forms with the concentric inside and outside double-deck access structure of the pivot 11 of vertically upward rotary supporting part 41 swimmingly.And rinse water is vertical equally, not can with introducing

port

12b, 12c collision or deflection, the disorder etc. of the concentric inside and outside double-deck access structure of formation and pivot 11, and directly over flowing into.

Consequently, rinse water can further improve the spin balancing and the stability of rotation washer jet 12 thus by importing connected

entrance

12d, 12e and balancedly importing

ejection path

33,34 around pivot 11.

For example, shape of cross section at minute water passage 48 is under the situation of circular, makes the radius of curvature of the inner surface of crooked route scope C form roughly more than 1/2 of internal diameter of branch water passage 48, can suppress to take place turbulent flow like this, can reduce the pressure loss etc., so be preferred.For example, the internal diameter of minute water passage 48 is made as 20mm, then the radius of curvature of crooked route scope C is good more than 10mm.

In addition, if the inner surface at the interior turning of crooked route scope C has corner angle, turbulent flow or air pocket taking place in the downstream easily then, therefore compares fully little getting final product of radius of curvature with outer turning side, but preferably be arranged to the curved surface of axis direction.

Therefore, in embodiment of the present utility model, the horizontal path domain B that stretches out has from the link position that is connected with clack box 133 and promptly is connected the part B1 that height and position H0 has a down dip towards rotary supporting part 41 side direction.By downward-sloping part B1, can guarantee that the height zone H1 that bending height zone H and clack box 133 are provided with has nothing to do.Therefore, can further suppress because the volume that wall caused of the rinse bath 4 on crooked route institute edge increases.In embodiment of the present utility model, by crooked route is set, can suppress the height of rotation washer jet 12 that is arranged at the bottom of rinse bath 4 lower, consequently, the space that can guarantee to place tableware 72 grades is bigger.

But because the part that connects height and position H0 is residual a rinse water being lower than, draining is let out in the draining of therefore preferred and clack box 133 together enforcement in time.

In addition, stretch out path domain B and stretch out with the height more than the horizontal direction shown in the double dot dash line of Fig. 4 or be inclined upwardly, thereby the lower end wall 48g that makes bending height zone H is more than the connection height and position H0 that it is connected with clack box 133 by making.Therefore, irrelevant with the height of roof 48h and shape, can avoid making rinse water to flow into clack box 133 and residue in midway, handle thereby can let out draining at clack box 133 these places.

Certainly, improve cleaning performance,, preferentially use as rotation washer jet 12 and the central portion that is disposed at bottom surface 4a to one of major general as a preferred form in order to dispose a plurality of washer jets.But, be not limited to this, also can to washer jet of major general as having the non-rotating washer jet 13 of riser portions 13b, horizontal part 13c, and optionally make its and other one or more washer jet work, thus the raising cleaning performance.

In this case, as shown in Figure 7, riser portions 13b forms, and on the position of leaving cleaning/draining pump 8, the link 13a of an end rises to the position higher than cleaning/draining pump 8.And horizontal part 13c is connected with the end of riser portions 13b, via or be positioned at the top of cleaning/draining pump 8, and around being arranged at least one wall of wall 4b.

Consequently, after the rinse bath 4 to dish cleaning machine body 2 supplied water, when the motor that drives cleaning/draining pump 8 was just being changeed, cleaning/draining pump 8 sucked the rinse water pressurization in the rinse bath 4, and sent to division box 14.14 whiles of division box or timesharing ground are to 33,34, the 35 fens water in one or more ejections path.Here, at least one of washer jet is non-rotating washer jet 13, other for the rotation washer jet 12.

And, optionally make a plurality of washer jets that contain a non-rotating washer jet 12 at least and one or

more ejections path

33,34,35 that these washer jets are had bring into play cleaning actions.Rinse water sprays in rinse bath 4 with various modes from a plurality of nozzle locations, cleans thereby can be cleaned thing in tableware 72 of

tableware basket

6,7 etc. to mounting.

Non-rotating washer jet 13 is by means of the branch water of division box 14, the rinse water of bottom surface 4a that makes rinse bath 4 by riser portions 13b and the 13c of supply level portion for injection.Horizontal part 13c be arranged at rinse bath 4 around at least one wall of wall 4b, and via or be positioned at the top of the cleaning/draining pump 8 that is provided with along this wall.Thus, comprise the riser portions 13c that leaves from cleaning/draining pump 8 and form to such an extent that lack via the water supply path length of division box 14 than the circuitous path that does not interfere with each other with cleanings/draining pump 8 from cleaning/draining pump 8.

In addition, make horizontal part 13c be positioned at the required predetermined altitude of rinse bath 4 by riser portions 13b, thereby can work with complementing each other with other washer jets.

In addition, shown in double dot dash line among Fig. 7, also can constitute riser portions 13b and horizontal part 13c by a plurality of ejections path 35,35a.Can make a plurality of ejections path 35, the 35a of riser portions 13b integrally formed, and can be connected or separate with a plurality of flow exports 42, the 42a that are arranged at branch water passage 48 simultaneously at link 13a.

Thus, non-rotating washer jet 13 has a plurality of

ejections path

35,35a, and the jeting area that can increase rinse water improves cleaning performance.And non-rotating washer jet 13 is connected with division box 14, can connect simultaneously or separate with respect to a plurality of flow exports 42, the 42a in minute water passage 48.

Next, other structures to division box and rinse bath describe.Figure 10 is the three-dimensional cutaway view of other structures of expression employed division box of dish cleaning machine of embodiment of the present utility model and rinse bath.

Divide water passage 48 to be embedded in bottom 49a, clack box 133 is integrally formed with the bottom surface 4a of the mode that links to each other at opening 133a and rinse bath 4.The division box 48 of other structure and precedent and clack box 133, spool 32 formed division boxs 14 do not change, and therefore shared parts and part are marked with prosign and omit explanation.

Consequently, therefore clack box 133 can reduce number of components and assemble man-hour owing to integrally formed with the bottom surface 4a of rinse bath 4, can further reduce cost.
