The specific embodiment

(embodiment 1)

Fig. 1 is the perspective cross-sectional slice of the dish cleaning machine that is provided with cleaning device among the present invention the 1st embodiment, and Fig. 2 is the sectional view of its key component, and Fig. 3 is the vertical view of this key component.As shown in these accompanying drawings, be provided with rinse bath 22 in the dish cleaning machine body 20, this rinse bath 22 can be by gate 21 opening/closing in addition, and tablewares etc. are cleaned thing 23 and are placed in earlier in the tableware basket 24, install to then in the rinse bath 22.Water intaking valve 25 is used for supplying with rinse water in rinse bath 22.After 26 pairs of rinse water of scavenging pump are pressurizeed, it is supplied in a plurality of spray-holes that are located on the washer jet 27, eject rinse water, carry out the 1st cleaning operation by washer jet 27.The bottom of rinse bath 22 is provided with the discharge outlet 28 that is connected with the suction side of scavenging pump 26, and this discharge outlet 28 is provided with the leftovers filter 29 that is used to collect leftovers.In addition, also be provided with the temperature sensor 31 that the heater that is used for heating 30 and being used to detects the temperature of rinse bath 22 in the dish cleaning machine.Draining pump 32 is used to discharge the rinse water in the rinse bath 22.Air blast 33 is sent into air by blast channel 34 in rinse bath 22, its exhaust then discharges by exhaust outlet 35.

The leading edge inboard of the opening portion of rinse bath 22 is provided with: the rinse water storage compartment 36 that is used to store the rinse water of high detergent concentration; With the ultrasonic vibration part 37 that is used to make these rinse water generation micronizes, outwards disperse.Be provided with in the ultrasonic vibration part 37: electrical energy is transformed into the ultrasonic oscillator 38 of mechanical oscillation and covers the lid 39 of ultrasonic oscillator 38.Be packaged with enclosing liquids 40 such as pure water, anti-icing fluid in the lid 39.When ultrasonic vibration part 37 is driven, will makes rinse water generation micronize and disperse, carry out the 2nd cleaning operation.In addition, when making ultrasonic oscillator 38 that vibration take place, can produce the phenomenon that the water surface rises, water flies out from the water surface in water.The rinse water A that rises (below be called " water column ") is recovered in the rinse water storage compartment 36 by top cover (also claiming " accepting part ") 41, also is provided with the cleaning agent that is used for dropping into to rinse water storage compartment 36 cleaning agents on this top cover 41 and drops into part 42 (see figure 3)s.In addition, the wall of rinse water storage compartment 36 is provided with breach, constitutes the connected component 43 that rinse water storage compartment 36 and rinse bath 22 are connected.

The basic operation process of dish cleaning machine is as follows.Earlier tableware etc. is cleaned thing 23 and installs in the tableware basket 24, again tableware basket 24 is installed in the rinse bath 22; Drop into cleaning agent, by gate 21 opening portion of dish cleaning machine main body 20 is closed again, the beginning cleaning operation.The order of operation is as follows: the advanced person is about to be cleaned the cleaning step that the dirt on the thing 23 cleans, carry out again carrying out making the drying steps that becomes dry attached to the water droplet that is cleaned on the thing 23 at last with attached to being cleaned the rinsing step that cleaning agent on the thing 23 and leftovers rinse out.

Below operational circumstances and effect in the distinctive cleaning process of the present invention are described.At first, the user drops into cleaning agent in the cleaning agent input part 42 of regulation, and the cleaning agent of input enters in the rinse water storage compartment 36.The input of cleaning agent structure both can adopt directly puts into structure in the rinse water storage compartment 36 like that among Fig. 3 by the user, the various structures such as formation that also can adopt the formation that transmits by passage and transmit linkedly with the shutoff operation of gate.As long as cleaning agent can be sent in the rinse water storage compartment 36, which kind of adopts constitute all is no problem.For the user can be rendered to cleaning agent on the position of regulation reliably, cleaning agent drop into part 42 or near the position of seeing clearly easily it on put on marks such as " cleaning agent inputs place " or do its color and peripheral part to such an extent that be not both effectively measure.

After closing gate 21, beginning operation, what at first carry out is the 2nd cleaning operation that the rinse water in the rinse water storage compartment 36 are dispersed.Its specific operation process is, makes water intaking valve 25 work earlier, adds water in rinse bath 22; Simultaneously, also in rinse water storage compartment 36, add water by connected component 43.The size of rinse water storage compartment 36 and water inlet water level are configured to deposit water about 20cc to 200cc, the water about 20cc to 100cc of preferably can packing into.Make under the occasion that rinse water circulates, cleans at scavenging pump 26, cleaning agent will be dissolved in the water about 2.5L to 4L.Therefore, about 10 times to 100 times rinse water in the time of in the 2nd cleaning operation, can forming detergent concentration for (cleaning) the 1st cleaning operation by washer jet 27 jet cleaning water.

Next, ultrasonic oscillator 38 is vibrated, such vibration is delivered in the rinse water in the rinse water storage compartment 36 by enclosing liquid 40, lid 39, rinse water is atomized, and the opening 41a from the both sides that are located at top cover 41 disperses to rinse bath 22.Different with existing cleaning way, the rinse water among the present invention is to disperse after micronize takes place again, even therefore rinse water has only the following few water yield of 100cc, also can be attached on all surfaces that is cleaned thing 23.Under the situation that does not increase employed cleaning dosage, just can form the very high rinse water of concentration.

But,, can produce the phenomenon of the rinse water shown in Fig. 2 from the surface rise using ultrasonic oscillator 38 to make under the occasion that rinse water disperses.The water yield in the water column that rises is considerably beyond the amount of dispersing in rinse bath 22.For example, in 1 minute, obtain under the occasion of the amount of dispersing of 3cc, in 1 minute, will produce the water column about 200cc.Therefore, under water column flies out the occasion of outside of rinse water storage compartment 36, then need than cleaning the required much more rinse water of the amount of dispersing.For instance, worked 10 minutes, then need the rinse water of 2L, the water yield that needs and existing cleaning way that is the 1st cleaning operation are equally matched.Therefore, under the occasion of the use cleaning dosage equal, will can not produce special effect with usual manner.But if rinse water is recovered in the rinse water storage compartment 36, then rinse water only need atomize and just can obtain the rinse water of high concentration about necessary several cc～tens of cc, and can reach very high cleaning performance.

In addition, also be provided with connected component 43 (see figure 3)s in the present embodiment 1.If water column flies to the outside of rinse water storage compartment 36, can in rinse water storage compartment 36, flow into the water identical with the water yield that flies out by rinse bath 22.Detergent concentration is sharply descended, and cleaning performance just performance does not come out.After being provided with top cover (accepting part) 41, just can prevent that concentration from descending, and obtains very high cleaning performance.

In addition, do not have special requirement for the rinse water particle diameter that becomes behind the particulate, but, be preferably 100 μ m or littler particle diameter in whole spaces that can arrive rinse bath 22.Particularly,, can form particulate floating state in rinse bath 22, can arrive on all surfaces that is cleaned thing 23 if can reach 20 μ m or littler.

As mentioned above, rinse water concentration among the present invention can reach the high concentration of the several times to 100 times of the detergent concentration in the existing rinse water, when such rinse water acts on dirt, cleaning agent will produce kickback with dirt or dirt is floated from the tableware surface, thereby cleaning performance is improved by leaps and bounds.The dirt of stubbornnesses such as lipstick that is difficult to wash fully with existing cleaning way and tea stain also can wash.In addition, after cleansing power improved, scavenging period just can shorten, and cleaning temperature is descended, thereby be expected to realize energy-conservation.

In general, detergent concentration is high more, and is just strong to the clean ability of dirt, so the concentration of rinse water is high more good more.Even if cleaning, high concentration can not carry out normal wash, owing to clean with the detergent concentration identical with existing mode in the 1st cleaning operation that carries out later, so special problem can not take place.In addition, if with the water yield that existing mode equates in also generate above-mentioned high concentration rinse water, then to use the cleaning agent of several times to 100 nearly times.No matter use a large amount of cleaning agents, still be on the position of the environment of preserving our planet economically, is also unfavorable obviously.

In addition, the isolated plant of dissolving cleaning agent is not set in the present embodiment 1, so though the initial period might not reach the high concentration of regulation, but, by heater 30 energisings to being used for rinse bath 22 inside are heated, water temperature by connected component 43 improves in the rinse water storage compartment 36 can promote the dissolving of cleaning agent.In addition, recovery structure makes the rinse water that reclaimed by top cover (accepting part) 41 and the cleaning agent of input come in contact, cleaning agent is produced stirring action, promote the dissolving of cleaning agent, thereby can improve the concentration of cleaning agent, successfully obtain having the rinse water of the normal concentration that can give play to cleaning performance.For instance, can as shown in Fig. 4 and Fig. 5,, the wash water that disappears that is recovered be directed to cleaning agent drop into part 42 1 sides at the arranged outside passage 41b of top cover (accepting part) 41; Perhaps as shown in Fig. 6 and Fig. 7, passage 41c is set, rinse water is guided to cleaning agent drop into part 42 1 sides, promote the dissolving of cleaning agent, improve the concentration of cleaning agent in the inboard of top cover (accepting part) 41.

In addition, dissolve fully, can make the concentration of rinse water reach maximum by the cleaning agent that makes input.In addition,, also can obtain having the rinse water of the normal concentration that can give play to cleaning performance, what special problem can not take place even have the part cleaning agent to fail to dissolve in the rinse water storage compartment 36.

For the rinse water of dispersing after the micronize can be arrived in whole spaces in the rinse bath 22, attached on whole tablewares, can consider that the free convection that utilizes heating to produce makes the way of the air generation convection current in the rinse bath 22 more equably.Specifically, heat continuously or intermittently, the air in the rinse bath 22 is stirred, can promote that rinse water is attached on the tableware by making the heater 30 that rinse bath 22 inside are heated.

Cleaning agent liquid in high concentration atomizes, disperses after the 2nd cleaning operation in rinse bath 22 carried out official hour, and scavenging pump 26 is started working; Simultaneously, eject rinse water, carry out the 1st cleaning operation from washer jet 27.At this moment, remain in the rinse water of using in rinse water in the rinse water storage compartment 36 and cleaning agent and the 1st cleaning operation and mix, and the rinse water of washer jet 27 injections can enter in the rinse water storage compartment 36.Because these rinse water can flow out from connected component 43, so needn't use special device, the cleaning agent of initial input can all be used in the 1st cleaning operation process.

In the 1st cleaning operation process,, dirt is produced mechanical momentum effect by jet cleaning water.The dirt of very big cleaning performance can be played for mechanical forces such as hardening property dirts, also sufficient cleaning performance can be reached.In addition, but it is peeled off or its adhesive ability has weakened for the dirt of failing to dispose fully from tableware in the chemical action by cleaning agent in the 2nd cleaning operation that at first carries out, also just can at an easy rate it be got and remove for those.

In addition, if only rely on the 1st cleaning operation that passes through washer jet 27 generations in the existing cleaning way to obtain under the occasion of powerful cleaning performance, need take to improve the measures such as hydraulic pressure of scavenging pump 26, the energy that consumes will increase, and produce economy variation, body volume increase, the rough sledding such as sound also can increase of working.But, by with the in addition combination of the 1st cleaning operation and the 2nd cleaning operation, use the scavenging pump identical, clean dosage with existing apparatus, just can realize the cleaning performance higher than existing mode.

In the 1st cleaning operation process, the same with existing mode, by the heaters 30 such as armored heater that are located in the rinse bath 22 are switched on, heat to rinse water in one side, cleans on one side.In addition, detect, when reaching set point of temperature or higher temperature, then stop energising heater 30 by the temperature of 31 pairs of rinse baths 22 of temperature sensor.

Rinse water is passed leftovers filter 29, is cleaned pump 26 and sucks, and is supplied in the washer jet 27 that is located in the rinse bath 22 by scavenging pump 26, sprays in rinse bath 22, and tableware 23 is cleaned; Then, turn back to once more in the discharge outlet 28, circulate repeatedly with such path.At this moment, the foreign material such as leftovers that split away off from tableware 23 flow into the leftovers filter 29 with rinse water, and the leftovers with the size that can't pass leftovers filter 29 is then by leftovers filter 29 catching.

After predetermined cleaning operation was finished, the rinse water that contains dirt was discharged to outside the machine by draining pump 32, and cleaning step finishes.Next, carry out rinsing step: change to new rinse water, make scavenging pump 26 work,, will rinse out attached to things such as being cleaned cleaning agent on the thing 23 and residual dish once more from washer jet 27 jet cleaning water.Such operation has been carried out after the official hour, discharges rinse water, and then adds new rinse water.Such operation will repeat repeatedly, and rinsing step generally will carry out about 3 times continuously.At last, rinse water is discharged to outside the machine, rinsing step finishes.

Next carry out drying steps.Make air blast 33 work, outer pneumatic transmission is gone in the rinse bath 22, discharge from exhaust outlet 35 again by blast channel 34.At this moment, also be energized in the heater 30, the effect of this two aspect by air blast and temperature impels attached to the water-drop evaporation that is cleaned on the thing 23.Drying process has been carried out just will finishing behind the official hour.

Using ultrasonic oscillator 38 to make under the occasion that particulate disperses, oscillator generally is not to be provided with vertically upward, but is arranged to skewedly, as shown in Figure 2, has an angle B.Be arranged under the occasion vertically upward, the water that rises/fly up from the water surface can fall down in identical position, and the height of water column is reduced, and the result can make the mist amount reduce.Therefore, it is best oscillator being tilted about 10 degree.

But under the occasion that ultrasonic oscillator 38 is obliquely installed, the water column of rise is also with run-off the straight.If adopt direct mode that this water column is recovered in the rinse water storage compartment 36, then the size of rinse water storage compartment 36 need be done greatlyyer as shown in Figure 8 like that.If reclaim but carry out rinse water after using top cover 41 that water column is blocked again, rinse water storage compartment 36 just can do miniaturization, thereby make the body 20 of dish cleaning machine also can realize miniaturization.In addition, owing to be to reclaim in stage before the end of water column disperses, the rate of recovery will uprise.Certainly, do not having under the situation of size restrictions, can resemble yet and not establish top cover Fig. 8, so can reclaim rinse water yet, reaching same effect.

In addition, though make top cover 41 generation dissolvings etc. make its danger that sustains damage owing to having added ultrasonic energy in the water column that takes place, having existed,,, can prevent that it from sustaining damage by being made by metals such as stainless-steel sheets by the place 44 that water column is flushed to.In addition, though do not illustrate especially among the figure, also can adopt in the part that is flushed to by water column metallic plate to be set or whole top cover 41 such as is made of metal at structure.For concrete formation, not special the qualification.

What ultrasonic vibration part 37 adopted is the structure that is covered ultrasonic oscillator 38 by lid 39, can prevent that like this ultrasonic oscillator 38 from directly contacting with the rinse water that contains cleaning agent and dirt, thus can with pollute to wait attached on the ultrasonic oscillator 38, make degradation phenomenon under its performance.Prevent trouble before it happens.But like that not using lid 39 but ultrasonic oscillator is set directly under the occasion in the rinse water as shown in Figure 9 also is no problem for the function that rinse water is dispersed.Therefore,, also can make outside ultrasonic oscillator 38 is exposed to, directly use according to place and shape difference are set.

In addition, the operating sequence in the present embodiment 1 is: the 2nd cleaning operation is carried out in advance than the 1st cleaning operation, promptly at first by the rinse water of high detergent concentration dirt is floated, next, had the cleaning of mechanical impulse force by scavenging pump 26.Like this, can very effectively the Fouling Cleaning of thin thickness be fallen; Simultaneously, for various dirts, also can reach the cleansing power higher than existing mode, this is very obvious.

In addition, also all without limits for the form that position and number, swivel nozzle etc. are set of the washer jet 27 that uses in the 1st cleaning operation.Except being arranged on the bottom of rinse bath 22, the back side, side and the end face etc. that also can be located at rinse bath 22 are located, and realize very high cleaning performance.In addition, also can not to allow all washer jets 27 water of jet cleaning simultaneously, but between scavenging pump 26 and washer jet 27, adopt the division box (not shown) of switching the rinse water stream, rinse water is sprayed in turn.Like this, only just can carry out the 1st cleaning operation with a spot of water yield.

In being provided with the dish cleaning machine of cleaning device of the present invention, all without limits for being provided with of the situation that is provided with of the switching mode of the shape of dish cleaning machine body 20 and size, gate 21, tableware and various parts etc.In addition, though what illustrate among the figure is the structure of desktop dish cleaning machine,, in the built-in dish cleaning machine below being contained in sink etc., also can adopt the present invention.In addition, be the example that has the cleaning and drying machine for tableware of dry-cleaning function though embodiment 1 illustrates, even do not establish the dish cleaning machine of functions/drying, also can reach same effect.

During operation, the user drops into cleaning agent earlier at the assigned position place, start cleaning operation then.After the operation beginning, the 2nd water intaking valve 45 is at first operated, and rinse water is added in the rinse water storage compartment 36.Next, be mixing component by motor-driven cleaning agent dissolver 47, form the high concentration cleaning agent liquid that is much higher than existing concentration.By being pre-formed the high concentration rinse water, by ultrasonic vibration part 37 rinse water is dispersed again, can clean from the high concentration rinse water of bringing into use at first of operation, thereby be expected to improve cleaning performance, shorten spray time.

In addition, because the connected component 43 that is communicated with rinse water storage compartment 36 and rinse bath 22 is not set, the cleaning agent composition can not dissolve (dilution) to rinse bath 22 1 sides, thereby can make the rinse water of dispersing have higher concentration, improves cleaning performance.

In addition, if employing is not established connected component 43, rinse water and be can't help to accept the structure that part 41 is reclaimed again, rinse water in the rinse water storage compartment 36 will reduce (1 minute reduces about 200cc) fast, so just needs to increase the volume of rinse water storage compartment 36.Under such occasion, obtain identical detergent concentration, certainly will need a large amount of cleaning agents.And accept part 41 parts such as grade rinse water is recovered in the rinse water storage compartment 36, just the water yield of rinse water can be suppressed to bottom line by setting.

In addition,, particulate is arrived in whole spaces in the rinse bath 22 equably, be expected to adhere to equably rinse water, the raising cleaning performance by driving air-blast device as particle sputtering device 48.In addition, in the short time rinse water is finished and be adhered to, therefore be expected to shorten working hours.

After the 2nd cleaning operation that driving ultrasonic vibration part 37 is carried out finishes, with the same the 1st cleaning operation that carries out among the 1st embodiment; Simultaneously, draining valve 46 can be opened, the rinse water that remains in the rinse water storage compartment 36 is discharged in the rinse bath 22, can make all cleaning agent compositions that dropped into originally all be used to carry out the 1st cleaning operation like this.

In addition; owing to be arranged to rinse bath 22 in the present embodiment and rinse water storage compartment 36 is separated; therefore, the jet cleaning water that also can advanced work is realized the 1st cleaning operation that cleans, make again high concentration rinse water generation micronize, disperse, carry out the 2nd cleaning operation.Under such occasion, at first carrying out being sprayed water etc. by scavenging pump 26 has the cleaning of mechanical impulse force, disposes bigger attachment; Next, the rinse water of high detergent concentration is had an effect, the dirt lip-deep at tableware, that be difficult to wash off with mechanical force that will harden is fully disposed it by strong chemical action, thereby improves cleaning performance.Particularly, can carry out high efficiency cleaning for the thicker dirt of thickness.After the 2nd cleaning operation is finished, with wash among the 1st embodiment the samely, drying process, finish whole cleaning operation then.

Figure 14 is the main sectional view of the dish cleaning machine that is provided with cleaning device among the present invention the 5th embodiment, and Figure 15 is the sectional view of its key component, and Figure 16 is the vertical view of key component.Identical among the basic comprising of dish cleaning machine and the embodiment 1, in addition, put on identical symbol with component parts identical among Fig. 1 to Figure 10.

Among Figure 14, ultrasonic oscillator 38 is covered by top cover 41, and top cover 41 is provided with the cleaning agent input part 42 that is used for cleaning agent is put into rinse water storage compartment 36, and the cleaning agent that the cleaning agent of input falls into rinse water storage compartment 36 is equipped with the 36a of portion.In addition, have breach on the part wall of rinse water storage compartment 36, constitute the connected component 43 that rinse water storage compartment 36 and rinse bath 22 are communicated with.Ultrasonic vibration part 37 described here is covered by top cover 41 is meant that top cover 41 covers the vertical direction part of ultrasonic vibration part 37 at least.

In addition, Figure 17 is the oblique view of seeing when rinse water storage compartment 36 and top cover 41 are observed in the inboard of rinse bath 22.When ultrasonic oscillator 38 is vibrated, the phenomenon that the water surface rises, water flies out from the water surface can take place, but the structure shown in the figure can be recovered to the water column that rises in the rinse water storage compartment 36 in water.What top cover 41 was provided with the water column that is used for directly accepting rise accepts part 51, and this is accepted part 51 and the rinse water that is used to make recovery and returns the rinse water recoverer 52 that cleaning agent drops into part 42 and form one.Structure in the top cover 41 is shown in the sectional view among Figure 18, the drowning position one side B of the rinse water that reclaims and the water surface C of the top of ultrasonic vibration part 37 are isolated by wall 53, and cleaning agent is put into the bottom 54 that wherein cleaning agent is equipped with the 36a of portion (below of cleaning agent input part 42) and is configured to: ultrasonic vibration part 37 1 sides (right side of Figure 18) are lower.Simultaneously, cleaning agent bottom 54 that the 36a of portion is housed also is configured to: the drowning position one side B (right side of Figure 18) of the rinse water of recovery is also lower.

For protect ultrasonic vibration part 37 be unlikely in the course of the work by foreign matter and dirt or tableware of falling etc. damage, be necessary to be provided with top cover 41.Simultaneously, in order to make equipment miniaturization, top cover 41 will be done as far as possible for a short time.But, top cover 41 do after the miniaturization, the water column that can produce generation again just is blocked, causes the problem that the particulate amount of dispersing reduces in short distance.

For this reason, be provided with opening portion 41a on the top cover 41, make water column pass this opening portion 41a, allow it be mapped to the outside of top cover 41 earlier with given size, accept rinse water by the part 51 of accepting in the outside of top cover 41 then, and rinse water is recovered in the rinse water storage compartment 36.Like this, can protect ultrasonic vibration part 37, can make top cover 41 realize miniaturization again, and can increase the generating capacity of the rinse water of dispersing, can make in the whole spaces in a large amount of rinse water arrival rinse baths 22, thereby obtain higher cleaning performance.

In addition, after accepting part 51 and being located on the top cover 41, the position relation that can make opening portion 41a and accept part 51 keeps very high precision, thereby can improve the rinse water rate of recovery of accepting part 51, and the required rinse water water yield is further reduced.In addition, accept part 51 and also can form one, perhaps be located on tableware basket 24 beyond the top cover 41 and the gate body 21 or form one with it, also can reach same effect with top cover 41.

In addition; by as shown in Figure 16 like that allow particulate that micronized rinse water passes by the 41d of portion being provided with on the side of top cover 41; rinse water also can be dispersed from the place beyond the above-mentioned opening portion 41a; more rinse water is dispersed in rinse bath 22, further improve cleaning performance.The particulate here passes the 41d of portion and is located at and drops into part 42 with cleaning agent and be on the side of an opposite side, like this, top cover 41 can prevent that not only the cleaning agent of putting in the cleaning agent input part 42 from dropping on the ultrasonic vibration part 37, and the generating capacity of the rinse water of dispersing is increased.

Figure 14 is the main sectional view of the dish cleaning machine that is provided with cleaning device among the present invention the 8th the embodiment, and Figure 15 is the sectional view of this key component, the vertical view of this key component of Figure 16 position.Identical among the basic comprising of dish cleaning machine and the embodiment 1.

Figure 17 is the oblique view of seeing when rinse water storage compartment 36 and top cover 41 are observed in the inboard of rinse bath 22.Wherein, what top cover 41 was provided with the water column of directly accepting rise accepts part 51, and accepts part 51 and the rinse water that is used to make recovery and return the rinse water recoverer 52 that cleaning agent drops into part 42 and be arranged to one.Structure in the top cover 41 is as shown in the sectional view of Figure 18, the water surface C of the drowning position E of the rinse water that is recovered and the top of ultrasonic vibration part 37 is isolated by wall 53, the bottom 54 that cleaning agent input cleaning agent wherein is equipped with the 36a of portion (cleaning agent drops into the below of part 42) is configured to like this, and promptly ultrasonic vibration part 37 1 sides (right side of Figure 18) are lower.Simultaneously, the bottom 54 that cleaning agent is equipped with the 36a of portion also is arranged to like this, and the drowning position E side (right side of Figure 18) of the rinse water that promptly is recovered is also lower.In addition, ultrasonic vibration part 37 is set at cleaning agent input cleaning agent wherein and is equipped with between 36a of portion (bottom 54) and the connected component 43.

Only drop into cleaning agent and add into water again, can't obtain the cleaning fluid of high detergent concentration.Though the words of the dissolver that use agitating device etc. are special-purpose, be easy to obtain the rinse water of high concentration, still, in present embodiment, by make the water column that produces by ultrasonic vibration when reclaiming and the cleaning agent of input come in contact, also can generate the rinse water of high detergent concentration.Current flow through the surface of cleaning agent, can improve dissolved efficiency, increase the detergent concentration in the rinse water storage compartment 36.In addition, under the occasion that cleaning agent is stirred by the current that reclaim, can further promote dissolving, rinse water storage compartment 36 in, generate the higher rinse water of concentration and also disperse, can further improve cleaning performance.Perhaps, can in the shorter time, generate the cleaning fluid of high concentration, so be expected to shorten the working time.

Adopting existing mode to make by scavenging pump 26 under the occasion that rinse water circulates, cleans, cleaning agent will be dissolved in 2.5L to 4L, about water in, therefore, compare with the detergent concentration that washer jet 27 ejects in rinse water, the rinse water when carrying out the 1st cleaning operation, in the 2nd cleaning operation, can generate concentration and increase to rinse water about 10 times to 100 times.

Be provided with after the connected component 43, when adding water in rinse bath 22, water also can be added in the rinse water storage compartment 36 simultaneously, so need not to be provided with special-purpose parts such as water intaking valve.In addition, when the water in the rinse bath 22 was discharged, the rinse water in the rinse water storage compartment 36 also can be discharged simultaneously, need not special-purpose drainage arrangement, can make device realize simplification, miniaturization like this, and manufacturing cost also is expected to reduce.Fly at water column under the occasion of outside of rinse water storage compartment 36, the water identical with the amount of flying out will enter in the rinse water storage compartment 36 from rinse bath 22, cause detergent concentration to descend rapidly, thereby can not bring into play cleaning performance.But, be provided with after the top cover (accepting part) 41, can prevent that concentration from descending, and obtains very high cleaning performance.

In addition, have connected component 43 to exist, the rinse water of the high detergent concentration that generates in the rinse water storage compartment 36 can spread, flow in the rinse water of storing up in rinse bath 22, makes the concentration of cleaning agent thinning.But, by 43 of connected components are arranged on the underwater, and reduce the area of connected component 43, situation about flowing out takes place in the rinse water that stockpiles in the rinse water storage compartment 36 in the time of can suppressing draining, suppress the decline of detergent concentration, make connected component 43 its due functions of performance simultaneously again.

In addition, because cleaning agent drops into bottom 54 that cleaning agent is equipped with the 36a of portion and is configured to ultrasonic vibration part 37 1 sides and becomes lower, therefore, the cleaning agent D that can make input as shown in Figure 18 accumulate in ultrasonic vibration part 37 1 sides like that, make detergent concentration be in very high state owing to coming in contact near the ultrasonic vibration part 37 with cleaning agent.Like this, the cleaning agent water of high concentration is dispersed in rinse bath 22, thereby can improve cleaning performance.In addition, because dropping into bottom 54 that cleaning agent is equipped with the 36a of portion, cleaning agent also is arranged to make drowning position E one side of the rinse water of recovery to become lower, therefore cleaning agent will be assembled this lower side of cleaning agent D input part, its upper section E has rinse water to fall again, like this, can improve with the contacting efficiency of cleaning agent and to its stirring capacity, thereby cleaning agent can be dissolved in the rinse water expeditiously, generate the rinse water of high detergent concentration.

In addition, the rinse water that is reclaimed by wall 53 is adjusted to and drops on the position E place isolated with the water surface C of ultrasonic vibration part 37 tops.If the rinse water that reclaims drops near the ultrasonic vibration part 37 the water surface, with the cleaning agent that accumulates in the bottom what can not take place and contact, and just flow on the water surface, and then form water column, upwards rise.Like this, the recovery of water column also is difficult to make the concentration of rinse water to be improved.For this reason, the like that water surface of the drowning position E of the water surface C of the top of ultrasonic vibration part 37 and recycle-water is cut off with wall 53 as shown in Figure 18.Like this, will produce the circulating water flow shown in the thick-line arrow among Figure 18, the cleaning agent D of the bottom that accumulates in rinse water storage compartment 36 can be stirred with very high efficient, detergent concentration can be improved.Particularly, owing to rinse water can be guided to the bottom of rinse water storage compartment 36, can reach higher cleaning performance.

Make rinse water storage compartment 36 and rinse bath 22 that the connected component 43 that is communicated with take place by setting, ultrasonic vibration part 37 is located at cleaning agent input cleaning agent wherein to be equipped with between 36a of portion and the connected component 43, and the circulation canal (arrow) of the water will be recovered to the cleaning agent side to the water column that ultrasonic vibration part 37 takes place the time is arranged on an opposite side of connected component 43 across ultrasonic vibration part 37, can do one's utmost to suppress the flowing of water of connected component 43 sides, prevent that cleaning fluid from outwards flowing out from connected component 43, thereby the higher rinse water of detergent concentration is dispersed.

In addition, though by allowing the cleaning agent that drops into that consoluet words take place, can reach maximum rinse water concentration, but, even if there is the part cleaning agent not dissolve in the rinse water storage compartment 36, as long as can access the rinse water of the normal concentration of having given play to cleaning performance, do not have any problem yet.

In order further to promote the dissolving of cleaning agent, effective method is to being used for heater 30 energisings to heating in the rinse bath 22, grades by interconnecting part and improves water temperature in the rinse water storage compartment 36.In addition, the heat that utilizes heater 30 to produce makes air generation convection current, and the rinse water that becomes particulate is dispersed in whole spaces in rinse bath 22, can make rinse water more equably attached on whole tablewares.By allowing the heater 30 that is used for to heating in the rinse bath 22 heat continuously or intermittently, the air in the rinse bath 22 is stirred, can promote that rinse water is attached on the tableware, thereby further improve cleaning performance.
