Fig. 2 is the table-ware washing machine structural map that vertical washing draining one pump is housed, Fig. 3 is the cutaway view of vertical washing draining one pump, and Fig. 4 is the partial sectional view and the left view thereof of vertical washing draining one pump, the 1st, and sink, the 2nd, hold the plate-basket of tableware, be located in the sink 1.The 3rd, to the pump of washings pressurizations, the 4th, to the heater of washings and tableware heating, the 5th, have the Washing spray nozzle of the jet 6 of jet cleaning water.The 7th, separate the screen pack of leftovers, the 8th, the control device that washing pump 3, heater 4 etc. is controlled.Said pump 3 have with centrifugal the 1st impeller to Washing spray nozzle 5 spue the 1st housing 10 of washings, with eddy current type the 2nd impeller 11 washings are discharged centrifugal the 3rd impeller 13 of being located at the 2nd impeller 11 back sides of the 2nd housing 12 outside the machine and the washings that in washing process, in the 2nd housing 12, spue.

In the middle of 2 housings, be provided with in addition at 3 directions and the 1st housing the 10, the 2nd housing 12 and with washings and guide the washings guide portion 15 that the head race 14 of pump 3 is communicated with into from sink 1.

The 16th, the 1st suction inlet that is communicated with the 1st housing 10 from washings guide portion 15, the 17th, the 2nd suction inlet that is communicated with the 2nd housing 12 from washings guide portion 15, the 18th, the 3rd suction inlet that is communicated with the 2nd housing 12 from washings guide portion 15.Above-mentioned in addition head race 14 is located at the suction inlet 17 of the 2nd impeller 11 below the side wall portion of the 2nd housing 12, promptly is located at the position lower than traditional approach.

Again, the 19th, to the motor that pump 3 drives, be bipolar induction motor.The 20th, the rotating changing device of this motor 19 (omitting diagram) is by doing positive and negative running to the capacitor of CD-ROM drive motor 19 and the main coil and the switching of ancillary coil connecting line of motor 19.In addition, the 1st impeller 9 and the 2nd impeller 11 and the 3rd impeller 13 are loaded on the output shaft of motor 19, and each impeller rotates to same direction.The 21st, with the drainage path of washings outside pump is discharged machine.

The 1st impeller 9 can be centrifugal, eddy current type or other modes.

The below action of explanation the 2nd embodiment.

At first, the tableware plate-basket 2 of packing into, be positioned over the assigned position in the sink 1 after, with switch connection not shown in the figures.In case switch connection, i.e. entry into service, control device 8 is at first carried out the water supply operation of supplying with quantitative washings in sink 1.Then, the washings by pump 3 pressurizations spray the main operation of washing of execution from the spray-hole 6 that is located on the Washing spray nozzle 5 with washing agent.After washing operation, promptly enter with pump 3 and will contain drainage procedure outside tableware etc. is washed the washings discharge machine of the dirt that falls through the master of stipulated time.Then, supply with again continuously washings the water supply operation, speckle with rinsing process, and the drainage procedure of the tableware of washing agent and leftovers from the 1st wash mill jet cleaning water with rinsing, finish whole washing procedure after so repeating 4 times.

Below describe the structure of said pump 3 in detail and in the action of washing procedure.Sink 1 is communicated with the 1st impeller 9 through the 1st suction inlet 16 from the washings guide portion 15 that the head race 14 with sink 1 bottom is connected with pump 3, is communicated with the 2nd impeller 11 from the 2nd suction inlet 15 simultaneously.In addition, be communicated with the 3rd impeller 13 through the 3rd suction inlet 18 from washings guide portion 15.Under this occasion, be set at when the rotation of the 1st impeller 9 and the 3rd impeller 13 clockwise directions, during 11 counter rotations of the 2nd impeller, can suck and the washings that spue from washings guide portion 15 respectively, constitute so-called centrifugal pump, turbulence pump respectively.In addition, general turbulence type pump can switch the direction that spues and suck by changing direction of rotation.

At main operation or the rinsing process washed, rotate by making motor 19 clockwise directions, and guide washings into the 1st impeller 9 from the 1st suction inlet 16 of washings guide portion 15.At this moment the 1st impeller 9 plays a role effectively, and washings are spued and wash to Washing spray nozzle 5.On the other hand, when same direction of rotation, the 2nd impeller 11 at first spues from the washings of the 2nd suction inlet 17 with drainage path 21, at this moment owing to the 3rd impeller 13 washings are spued in the 2nd housing from the 3rd suction inlet 18, the a part of washings that spue return the washings guide portion from the 2nd suction inlet, and remaining washings then are trapped in the drainage path 21.

Thereby being not only does not have air in the 2nd housing 12, the 1 housings 10 yet and enters, can be stably to Washing spray nozzle 5 washings that spue.

The optimal design of staying blade external diameter that washings water level in the drainage path 21 then can be by the 3rd impeller 13 and blade height etc. keeps stable.

In addition, when drainage procedure, make motor 19 do the inhour rotation by rotating changing device 20, and washings are guided into the 2nd impeller 11 from the 2nd suction inlet 17.At this moment the 2nd impeller 11 plays a role effectively, outside washings discharge machine.And then, same during with washing procedure as the 3rd impeller 13 of receded disk impeller, washings are spued in the 2nd housing 12 from the 3rd suction inlet.That is the effect that performance improves drainability when draining.

In case the execution drainage procedure, along with the reduction of washings water level, the 1st impeller 9 becomes fully and only stirs air state, and the idle running sound of the 1st housing 10 is just very little.Also have,, can make the washings that remain in the 1st housing 10, can alleviate the idle running sound in the 1st housing 10 to washings guide portion 15 drippages because at this moment motor 19 suspends.

And in a single day the washings water level reduces after carrying out drainage procedure, and 10 of the 1st housings become from washings guide portion 15 suction air state, and washings do not spue.And along with the decline of washings water level, the 1st impeller 9 becomes fully and only stirs air state, and the idle running change of tune of the 1st housing 10 gets very little.

And owing to washings are guided into the 2nd impeller 11,, produce in the short time at the utmost point that draining closes to an end so make the 2nd impeller 11 mix the air rotation and to produce the water level of noise very low from the 2nd suction inlet 17.

As mentioned above, by the 2nd impeller 11 of pump 3 being located at the below of the 1st impeller 9, and head race 14 is located at the suction inlet of the 2nd impeller 11 below the side wall portion of the 2nd housing 12, i.e. the position lower than traditional approach, can reduce discharge level, thereby reduced the surplus of addle, can improve in the next rinsing process washings to the dilution factor of dirt, improve the rinsing function.Thereby, even reduce the washings consumption of rinsing number of times or each rinsing, the rinsing function that still can obtain stipulating.Again, centrifugal pump more can obtain the washing of table-ware washing machine effectively and export with the necessary pump of pump than turbulence type pump, thus self-evident, can realize the miniaturization of drive motor and wash mill.

In traditional pump, adopt washing pump water sucking mouth and the draining structure of water sucking mouth is set respectively, and pump of the present invention is to come dual-purpose with head race 14 these 1 pipeline, so can save suction parts such as flexible pipe and flexible pipe clamp.

About the direction of rotation of motor, no matter the present invention is used to the washings that spue to which direction of rotation, can both obtain same effect.

As mentioned above, present embodiment is to be provided with the 3rd receded disk impeller at the back side of the 2nd impeller, and the suction inlet of the 2nd impeller is located at the side wall portion of the 2nd housing, through this suction inlet, the head race that washings are introduced the pump from sink is communicated with the 2nd housing, thereby no longer need check valve etc., can with simple construction of stable the washing function that obtains stipulating, noise in the time of can reducing simultaneously the washing draining, improve drainability, improve the rinsing function, reduce cost, and obtain making the table-ware washing machine of tableware spatial accommodation increase because of the wash mill miniaturization.

Below be the 3rd embodiment of the present invention.Fig. 5 and Fig. 6 are the cutaway views of vertical washing draining one pump, and the essential structure of structure member is identical with the 2nd embodiment shown in Figure 2, its explanation of Therefore, omited.

22 is the 2nd impeller 11 installation portions on motor 19.The 23rd, in washings guide portion 15, be fixed in the roughly discoid resistance body of the between centers of the 1st impeller 9 and the 2nd impeller 11, its external diameter is greater than the external diameter of the 3rd suction inlet 18.On the disk of the 2nd impeller 25, and be provided with the hole 24 that is communicated with the 3rd impeller 13 1 sides in the position of swirl vane inboard again.

In addition, the 1st impeller 9 can be centrifugal, eddy current type or other modes.

The elemental motion of present embodiment and the action of washing procedure are identical with the 2nd embodiment, omit explanation.

When adopting conventional construction, in washing procedure, the suction direction of the inhalation power of the 3rd impeller 13 and the 1st impeller 9 antithesis, so the 1st impeller 9 is promptly become suction resistance, the reduction that causes washings to spue and press, and, can alleviate the influence of 13 pairs of inhalation powers of the 3rd impeller by resistance body 23 is set between the 1st suction inlet 16 and the 3rd suction inlet 18.Thereby, can reduce the suction resistance of the 1st impeller 9, improve the washings pressure that spues.

The design optimization of blade external diameter that the washings water levels that are detained in the drainage path 21 can be by the 3rd impeller 13 and blade height etc. keeps stable in addition.

In addition in the conventional washing operation, the installation portion 22 of the 2nd impeller 25 on motor 19 piled up foreign matter easily because of no washings flow through, now produced the current of washings, thereby can reduce the accumulation of foreign matter significantly owing on the disk of the 2nd impeller 25, having the hole 24 that is communicated with the 3rd impeller 13 1 sides.

When adopting conventional construction, the washings that pressurizeed and spued by the 3rd impeller 13 spue in the 2nd housing 12 in addition, so take place acutely to conflict with the washings that pressurizeed and spued by the 2nd impeller 25.Especially in the drainage procedure latter stage that is mixed with air, washings and air are mixed in together, and huge noise can take place.

Yet in the present embodiment, owing between the 2nd impeller 25 and the 3rd impeller 13, have hole 24, and reduced pressure differential between 2 impellers, can reduce drainage noise significantly.Quantity as for hole 24, from eliminating the pressure differential between the 2nd impeller 25 and the 3rd impeller 13 and keeping the balance of impeller self rotation, no doubt can offer a plurality of in the position of an object, even but its quantity is 1, even the position is set is not an object's position, can fully obtain the effect of present embodiment yet.

In drainage procedure, do the inhour rotation by make motor 19 with rotating changing device 20, and guide washings into the 2nd impeller 11 from the 2nd suction inlet 17 of washings guide portion 15 again.At this moment the 2nd impeller 11 plays a role effectively, and washings are discharged outside the machine.In this occasion if adopt conventional construction, because the air in the 1st housing 10 is attracted by the 3rd impeller, owing to causing performance, reduces the air of sneaking in early days in the 2nd housing 12, and in the present embodiment, because the effect of resistance body 23, the air that is stranded in the 1st housing is difficult to be attracted by the 3rd impeller 13, sneaks into the interior time of the 2nd housing 12 so can postpone air.

In other words, can keep drain function more longways during draining, reduce the surplus water yield.Because the same during with washing procedure, be washings to be spued in the 2nd housing 12, in addition so improved drainage performance from the 3rd suction inlet 18 as the 3rd impeller 13 of receded disk impeller.

In drainage procedure, when adopting conventional construction, the air that is stranded in the installation portion 22 of the 2nd impeller 25 on motor 19 is difficult to discharge, the gas shock sound promptly takes place at the washing procedure initial stage, and in the present embodiment, air is easy to discharge outside pump 3, so the noise at washing procedure initial stage can not take place.

As mentioned above, because on the disk of the 2nd impeller, have the hole that is communicated with the 3rd impeller one side in the position of swirl vane inboard,, also can reduce the noise of table-ware washing machine when washing procedure initial stage and draining significantly so not only can prevent the accumulation of foreign matter in pump.

About the direction of rotation of motor, the whichever direction of rotation is used to the washings that spue in addition, and the present invention can obtain same effect.

As mentioned above, the table-ware washing machine of the 3rd embodiment roughly becomes discoid resistance body by being provided with between the 1st impeller and the 2nd impeller, has reduced surplus water and has improved the rinsing function, but and conserve water, improved washing function and drain function.Because on the disk of the 2nd impeller, the hole that is communicated with the 3rd impeller one side that has in the swirl vane inboard not only can prevent the accumulation of foreign matter in pump in addition, and the noise can make table-ware washing machine reduce washing procedure initial stage and draining significantly the time.

The 4th embodiment of the present invention below is described.

Fig. 7 and Fig. 8 are the cutaway views of vertical washing draining one pump, and the essential structure of its structure member is identical with the 2nd embodiment shown in Figure 2, its explanation of Therefore, omited.It is characterized in that newly having with washings guide portion 15 and the hole 27 that the 2nd housing 26 is communicated with, have special effect.In addition, the 1st impeller 9 can be centrifugal, eddy current type or other modes.

The below action of explanation the 4th embodiment.The elemental motion of its washing procedure is identical with described the 2nd embodiment, its explanation of Therefore, omited.

Especially in washing procedure, by the 3rd impeller 13 washings that in the 2nd housing 26 and drainage path 21, spue, though can prevent to suck air from drainage path 21, but when screen pack 4 serious obstructions, it is not enough that the inhalation flow of supply pump 3 promptly becomes, and pump 3 just can suck washings in drainage path 21.As a result, pump 3 is absorbed in utmost point labile state, and the washings that spue outside machine take place sometimes, makes phenomenons such as heater 7 empty burnings.

In order when pump 3 plays pendulum, not make outside the washings outflow machine yet, the surface that must reduce the 3rd impeller 13 ability that spues.And when adopting structure of the present invention, a part of washings that spue from the 3rd impeller 13 can be from the hole 27 return washings guide portion 15 once more.

In other words, can under the situation of the ability that does not reduce the washings that in the 2nd housing 26, spue, reduce the ability that spues on surface.Even thereby under the labile state in washing procedure, washings can not take place yet discharge the outer situation of machine.In addition, even 1 of the quantity in hole 27 even the position is set not at an object's position, still can fully obtain effect of the present invention.

As mentioned above, owing to have the hole that is communicated with the 2nd housing from the washings guide portion, especially can make table-ware washing machine when washing, keep stable water level in the drainage path.

The 5th embodiment of the present invention below is described.

Fig. 9 and Figure 10 are the cutaway views of vertical washing draining one pump, and the essential structure of its structure member is identical with the 2nd embodiment shown in Figure 2, its explanation of Therefore, omited.It is characterized in that newly having with washings guide portion 15 and the hole 29 that the 1st housing 28 is communicated with, have special effect.In addition, the 1st impeller 9 can be centrifugal, eddy current type or other modes.
