Below operational circumstances in the cleaning and drying machine for tableware with said structure and effect are described.
During to wash dishes, at first slide mass 27 is pulled out in body 26, will be cleaned thing that is tableware and install in the rinse bath 1, then with slide mass 27 pushed home, the beginning cleaning operation.After cleaning operation begins, at first open water intaking valve 22, to rinse bath 1, supply water, close water intaking valve 22 after reaching the water yield of regulation, stop into water from water inlet pipe 23.Then, heater 5 and cleaning device 4 that is scavenging pump 3 begin operation, and from washer jet 2 ejection hot water, hot water is sprayed onto and is cleaned thing is on the tableware, and constantly circulates.Can rotate under the reaction force acts of washer jet 2 when the ejection rinse water, make rinse water be ejected into all being cleaned on the thing, clean cleanliness factor thereby can improve.
Though only enumerated the example that makes heater 5 work, utilizes warm water to clean here, being cleaned under the few situation of dirt on the thing, heater 5 is not worked, only rely on supply water temperature to clean; On the contrary, be cleaned under the very dirty situation of thing, can also after adding washing agent, cleaning.Cleaning operation is opened draining valve 24 after finishing, and makes rinse water be discharged to the outside of body 26 from drainpipe 25.Draining is closed draining valve 24 after finishing.
In the flushing operation that next carries out, under the situation that does not drop into washing agent, the same water that adds earlier with cleaning operation, make heater 5 and scavenging pump 3 work then, make washer jet 2 ejection warm water, warm water is ejected into and is cleaned thing is on the tableware, and constantly circulates.Be cleaned the drying process that thing becomes dry owing to also will make after the flushing operation, be cleaned thing and warm so in flushing operation, preferably make in advance.In addition, if carry out flushing operation, can also carry out sterilization processing with 70 ℃～80 ℃ high-temperature water.After flushing operation finishes, the same when finishing with cleaning operation, the flushing water in the rinse bath 1 is discharged.
In the drying process of next carrying out, owing to will will discharge because of the air that washes in the rinse bath 1 that becomes hot and humid, make and be cleaned the thing exsiccation, so will allow air blast 6 work, shunt in the gas passage 15 in gas passage 14 and the rinse bath outside with air quantity distributor 12 simultaneously, outer gas is sent in mixing arrangement 13 and the rinse bath 1.
Begin the initial stage in drying, for preferentially but with air cooling in the rinse bath, at first reduce the blow rate required of air blast 6, open the air door 29a of outer gas passage 14 sides, make the air quantity that flows to outer gas passage 14 sides more than gas passage 15 sides in the rinse bath, allow and collaborate/mix among the interflow parts 13a of gas (shown in the white arrow of Fig. 2) in mixing arrangement 13 in the relative less hot and humid rinse bath of the bigger outer gas of air quantity (shown in the black arrow of Fig. 2) with air quantity, and the mixed airflow flow velocity after gas in the rinse bath and outer gas collaborate is slowed down at cross section enlarged 33 places, promote condensation by cooling, exclude moisture, make by mixing component 34 again that gas and outer gas mix equably in the rinse bath, make at last through supercooling and the gas that reduced moisture from exhaust outlet 7 outflows.
Then, along with the carrying out of drying process, the reduction gradually of humidity in the rinse bath 1 preferentially makes the operation of desiccation in the rinse bath 1 this moment, thereby increases the blow rate required of air blast 6, makes two air door 29a and 29b in the passage be full open position.Under the state that air door 29a and 29b open fully, the basic of distribution channel resistance separately of gas passage 15 carries out in outer gas passage 14 and the rinse bath, the air quantity that is assigned to gas passage 15 in the rinse bath is more than the air quantity to outer gas passage 14 sides, and carrying out with the drying is the pushing wind manipulation of main purpose.
Like this, the aperture that causes air door 29 by the blow rate required by air blast 6 changes, the distribution of air flow of gas passage 15 is pressed according to fluid carries out, make again through supercooling and the gas that reduced moisture and flow out from exhaust outlet 7, can the simplification device structure, reduce manufacturing cost.
Particularly utilizing high-temperature water to carry out under the situation of flushing operation, directly do not discharge in order to make the hot and humid air in the rinse bath 1 from exhaust outlet 7, begin the initial stage to reduce delivery temperature in drying process, 17 pairs of air blasts 6 of air quantity control module by control device 16 are controlled, and make the air quantity of delivering to outer gas passage 14 sides more than the air quantity of delivering to gas passage 15 sides in the rinse bath.
For the interflow parts 13a by mixing arrangement 13 in hot and humid rinse bath, sneak in the gas outside gas, make its cooling and make that the contained moisture of gas carries out condensation in the rinse bath, must make that gas and outer gas evenly and promptly mix in the rinse bath.
Illustrated among Fig. 3 that sectional area with passage is made as certain value and aspect ratio and the relation characteristic figure of channel pitch between (thickness of supposing conduit wall is zero) when two channel parallel are provided with.Among Fig. 3, the sectional area of supposing passage is 1000mm
2, and the aspect ratio of square-section is big more, two passages (two strands of air-flows) can be provided with the closer to.With aspect ratio is that 1 situation is compared, and aspect ratio is that channel pitch under 4 the situation is from reducing by half basically.Therefore, by aspect ratio being arranged to be equal to or greater than 4, being made the air-flow of two passages close, take place under the situation at interflow at the conduit wall back two strands of air-flows that disappear, air-flow can mix better.
In the present embodiment, because gas passage and outer gas passage all are the passage that aspect ratio is very big, the cross section is slightly rectangular separately in the rinse bath, and long limit one side interconnects and makes the gas interflow, therefore, can promote to mix by being mixed with each other between the gas of thickness attenuation, and gas is mixed in four corner equably.When drying process, can be in the space of compactness for rinse bath in hot and humid air (gas in the rinse bath) be mixed into sufficient outer gas reliably, thereby can cool off gas in the rinse bath.Like this, the humiture of discharging gas can be reduced, and can prevent the hot blast sense reliably, and realizes the miniaturization of body.
In addition, particularly the gas air quantity is far longer than the drying process initial stage of gas air quantity in the rinse bath, is under the situation of main purpose to reduce delivery temperature outside, outside the interflow parts 13a that collaborate the side of gas passage 14 gas passage 15 in rinse bath, owing to producing turbulent flow because of bending in the gas passage 15 in the rinse bath, so outer gas can produce mixing effect to gas in the rinse bath, be diffused into simultaneously in the whole zone, can reduce and mix uneven phenomenon generation, make Temperature Distribution reach impartial.
In addition, because gas passage 15 waits the aspect ratio of each passage all to be arranged to more than or equal to 4 with outer gas passage 14 in the rinse bath, so collaborate again after can making the fluid thickness attenuation of flowing through interior gas passage 15 of rinse bath and outer gas passage 14 respectively.Like this, mutual easier the carrying out of mixing between is even also can high efficiencyly mix in the zone slowly at flow velocity.
In addition, be arranged to almost equal (Wa ≒ Wb) by long edge lengths Wb with gas passage 15 in the long edge lengths Wa of outer gas passage 14 and the rinse bath, and the long limit that makes like that as shown in FIG. interconnects, can make the space that is provided with of each passage realize minimizing, the structure of mixing arrangement 13 also can realize miniaturization.
In addition, be arranged to longer than the length Wb on the long limit of gas passage 15 in the rinse bath by length Wa with the long limit of outer gas passage 14, and the long limit of gas passage 15 in the rinse bath is located at the inboard (not shown) on the long limit of outer gas passage 14, can guarantee outside gas provides reliably in the rinse bath that the whole regional introversion at long side direction (width) becomes hot and humid gas and stir, can prevent to produce the unmixing gas of part, make the temperature of discharging gas reach stable.
In addition, gas passage 14 is arranged to close under the situation of interflow parts 13a of rising stream 31 outside, even in rinse bath under the air quantity of the gas occasion seldom, outer gas also can be cleaned gas heating in the groove and rise, to exhaust outlet 7 side flow, therefore mixed ascending air is also very stable, becomes the uprising gas that change has been reduced, and can reduce the temperature inequality that produces because of the fluid change.And, because the centre is separated with decline stream 30, can prevent also that in cleaning operation and flushing operation process rinse water from flowing in the outer gas passage 14, and in the rinse bath that causes because of free convection of minimizing gas to the leakage of exhaust outlet 7.
In addition, in the downstream that is located at interflow parts 13a and channel cross-sectional area became big cross section enlarged 33, the flow velocity of the mist in the rinse bath behind the interflow of gas and outer gas was slowed down, variations in flow such as generation eddy current.Like this, not only can promote to mix, can also rely on cooling to promote condensation simultaneously, quicken the eliminating of moisture.
In addition, at the mixing component 34 in the downstream that is arranged in interflow parts 13a, the mixed airflow of gas and outer gas is stirred consumingly in the rinse bath, promotes its mixing.Like this.Can mix equably between gas and the outer gas in the rinse bath, cool off, thereby can promote the atomizing of moisture.
In addition, forms mixing component 34, can realize stirring reliably gas by the planar body 36 of convex shape that extends by 32 width along the hybrid channel.In addition, because planar body 36 can be one-body molded with conduit wall, can the simplification device structure, reduce manufacturing cost.
In addition, by in the planar body 36 on the partial width of hybrid channel 32 set notch part 37, can cause on the whole width of hybrid channel 32 that gas turbulent flow takes place and is stirred, thereby can promote the Temperature Distribution in the whole zone of hybrid channel to reach stable.
In addition, though above only enumerated gas passage 15 in outer gas passage 14 and the rinse bath the cross section be the example of complete rectangle, but also the bight in cross section can be arranged to have certain curvature for easy to process, perhaps form the shape of the easy processing such as trapezoidal grade that has demoulding inclined plane.Moreover, make to have bigger curvature on the long limit or flat channel concavo-convex, that formation can improve air-flow is set also to be fine certainly.
In addition, though above only enumerated and rely on air quantity distributor 12 will distribute to the example of gas passage 15 in outer gas passage 14 and the rinse bath from air blast 6 air blast, in the gas passage 15 the air blast (not shown) is set respectively in gas passage 14 and the rinse bath outside, then each air blast is controlled.
In addition,, also can utilize spring etc. to carry out reinforcing, be applied with the strength of closing though only enumerated structure that air door 29 relies on its deadweight to close here.Utilize the elastic force of spring to close, can also improve the free degree of mounting position.
As mentioned above, in the mixing arrangement of present embodiment, be made as the channel shape of the very big square-section of aspect ratio respectively by the outer gas passage of gas passage in the rinse bath that will import gas in the rinse bath and the outer gas of importing, and will grow limit one side and interconnect gas is collaborated, can in the drying process process, in hot and humid rinse bath, sneak into abundant outer gas in the gas reliably by a very compact space, gas in the rinse bath is cooled off, thereby can reduce humiture, prevent the hot blast sense reliably, and realize the miniaturization of body.
In addition, the mixing arrangement of present embodiment is by being provided with the interflow parts that outer gas passage is collaborated the gas passage in the rinse bath that extends along rectilinear direction from the side, can be in rinse bath gas passage internal cause crooked and cause turbulent flow, gas in the rinse bath is played stirring action, make outer gas be distributed to various piece simultaneously, reduce and mix inequality, it is impartial that Temperature Distribution is occurred.
In addition, the aspect ratio of gas passage and outer gas passage is more than 4 to the mixing arrangement of present embodiment in the rinse bath by being provided with, make the thickness attenuation of the fluid that flows respectively in interior gas passage of rinse bath and the outer gas passage, gas and the enough easier mixing of outer gas phase mutual energy in the rinse bath like this is even also can carry out high efficiency mixing in the zone slowly at flow velocity.
In addition, the mixing arrangement of present embodiment can effectively utilize the space by the long edge lengths of gas passage in the rinse bath and outer gas passage is arranged to about equally, realizes the miniaturization of mixing arrangement.
In addition, the mixing arrangement of present embodiment is by being arranged to the long edge lengths of outer gas passage the long edge lengths greater than gas passage in the rinse bath, and gas passage in the rinse bath is located at the inboard of outer gas passage, gas and stirring outside can providing reliably in the gas in the rinse bath that becomes hot and humid in the whole zone of long side direction prevents to produce the phenomenon that portion gas mixes.
In addition, in the mixing arrangement of present embodiment, be provided with in the gas passage in the rinse bath and make decline stream that gas flows downward from the rinse bath inlet and outlet and the rising stream of upwards turning back then, and outer gas passage is arranged to close on described rising stream and is formed the interflow parts, even in rinse bath, also can reduce the change of uprising gas under the air quantity of the gas situation seldom, thereby reduce the non-uniform temperature that produces because of change of fluid.In addition, rinse water enters that phenomenon in the outer gas passage can be prevented and rinse bath in gas also can alleviate because of the phenomenon of free convection to the exhaust outlet external leakage.
