In above-mentioned dish cleaning machine 1, after the cleaning or rinsing end that are cleaned thing 10, the motor reverse rotation of pump 11.Thus, the rinse water that accumulates in the portion of accumulating 12 imports and exports the G of portion with the rinse water that remains in the branch water portion 15 via discharge outlet 12a and rinse water, is aspirated by pump 11, is discharged to the outside of rinse bath 2 through drainpipe 32.
Next with reference to Fig. 4, a series of action of dish cleaning machine 1 is described.Fig. 4 is the flow chart of action summary of the dish cleaning machine of expression embodiments of the present invention 1.
As shown in Figure 4, at first, discharge residual rinse water in the rinse bath 2, open feed water valve 31a so that running water supplies to (S1: draining/water supply step) in the portion of accumulating 12 from feed pipe 31.
Next, add washing agent in the running water in supplying to rinse bath 2, obtain rinse water thus, this rinse water is sent to the 1st～the 4th stream Ra～Rd by pump 11.Thus, rinse water from rotation washer jet 3,4,7 and fixedly washer jet 5 be ejected into and be cleaned on the thing 10, clean (step S2: cleaning step) to being cleaned thing 10.
Under this situation, be ejected into the rinse water that is cleaned thing 10 and accumulate portion 12, accumulate in once more in the portion of accumulating 12 along the inflows such as wall of rinse bath 2.The rinse water that is accumulated in the portion of accumulating 12 is sent to the 1st～the 4th stream Ra～Rd by pump 11 once more, is ejected into from each rotation washer jet 3,4,5,7 to be cleaned on the thing 10.Like this, clean when being cleaned thing 10, rinse water is in the inner loop of rinse bath 2.
After being cleaned the cleaning end of thing 10, being used to clean the rinse water that is cleaned thing 10 and discharging through drainpipe 32 by pump 11.Afterwards, by opening feed water valve 31a, supply with running water (step S3: draining/water supply step) once more to the portion that accumulates 12 of rinse bath 2.
Next, the running water that is fed in the rinse bath 2 is sent to the 1st～the 4th stream Ra～Rd as rinse water by pump 11.Thus, rinse water is ejected into from each rotation washer jet 3,4,5,7 and is cleaned on the thing 10, carries out rinsing (step S4: rinse step) to being cleaned thing 10.
In the present embodiment, according to the difference by the turbidity of turbidity detection portion for example shown in Figure 1 60 detected rinse water, the number of times of the rinse step of S4 is also different with the time.The turbidity of rinse water will be described below with the number of times of rinsing and the relation between the time.
After the rinsing end that is cleaned thing 10, the rinse water that is used for rinsing is discharged through drainpipe 32 by pump 11.Afterwards, open feed water valve 31a, the portion that accumulates 12 to rinse bath 2 supplies with running water (step S5: draining/water supply step) once more thus.
Next, by heater 14 actions, the running water that is accumulated in the portion of accumulating 12 inside is heated to the temperature of regulation.Afterwards, heated running water is sent to the 1st～the 4th stream Ra～Rd as rinse water by pump 11.Thus, the rinse water that is heated to set point of temperature is ejected into from each rotation washer jet 3,4,5,7 and is cleaned on the thing 10, heats rinsing (step S6: rinse step) to being cleaned thing 10.Thus, can utilize heat to sterilize to being cleaned thing 10, and the drying efficiency that is cleaned thing 10 in the drying steps after improving.
After the heating rinsing that is cleaned thing 10 finished, the rinse water that is used to heat rinsing was discharged (step S7: drain step) by pump 11 through drainpipe 32.
At last, stop the action of pump 11, drying section 72 actions for example shown in Figure 2.Drying section 72 makes the inner space of rinse bath 2 produce air-flow, therefore is heated to the inner loop of the atmosphere of set point of temperature at rinse bath 2 by heater 14.Come drying to be cleaned thing 10 (step S8: drying steps) thus.Afterwards, finish a series of release of dish cleaning machine 1 by the drying that is cleaned thing 10.
In addition, though above do not mention, in practice, in the cleaning step of step S2, rinse water also is heated to the temperature of regulation by heater 14.
Next, with reference to Fig. 5 and Fig. 6 turbidity detection portion 60 is elaborated.
Fig. 5 is the assembling stereogram of turbidity detection portion 60 as shown in Figure 1.Fig. 6 is the longitudinal section of turbidity detection portion 60 as shown in Figure 1.
As shown in Figure 5 and Figure 6, turbidity detection portion 60 mainly is made of lower cover 610, seal 620, sensor housing 630, sensor support housing 640, loam cake 650, optical sensor 64 and turbidity detection nozzle 5x.
The part of the end face of lower cover 610 configuration examples rinse bath 2 as shown in Figure 1.That is, to form its part outstanding downwards for the end face of rinse bath 2.Central portion at lower cover 610 is formed with peristome 611.In addition, on lower cover 610, be formed with 2 screwed holes 612 near peristome 611 ground.
In assembling during turbidity detection portion 60, seal 620 is installed along the inner edge of the peristome 611 of lower cover 610.Under this state, the sensor housing 630 with ship shape (comprising ship shape) roughly embeds the peristome 611 of lower covers 610 across seal 620.As the material of sensor housing 630, for example use polymethylpentene (PMP) resin.In this case, sensor housing 630 has light transmission.
Central portion at sensor housing 630 is formed with the spatial accommodation 630S that is used to hold sensor support housing 640.In addition, on sensor housing 630, be formed with 2 through holes 639 near spatial accommodation 630S ground.
Embed under the state of lower cover 610 at sensor housing 630,, bolt N is installed in 2 screwed holes 612 of lower cover 610 via 2 through holes 639 of sensor housing 630.Thus, sensor housing 630 is fixed on the lower cover 610 reliably.In addition, guarantee watertightness between sensor housing 630 and the lower cover 610 by seal 620.As shown in Figure 6, in the bottom surface central authorities of the sensor housing 630 that forms spatial accommodation 630S, be formed with the rectangular concavity portion 631 in cross section of depression upward.
Light-emitting component 64a that printed circuit board (PCB) 64P is installed on sensor support housing 640, constitutes by light emitting diode and the photo detector 64b that constitutes by photodiode.Constitute optical sensor 64 by printed circuit board (PCB) 64P, light-emitting component 64a and photo detector 64b.In the present embodiment, as optical sensor 64, use the optical sensor of infiltration type.The terminal of light-emitting component 64a and photo detector 64b is connected with printed circuit board (PCB) 64P.
The sensor support housing 640 that optical sensor 64 is installed is accommodated among the spatial accommodation 630S of sensor housing 630.Under this state, relative mutually with photo detector 64b across the concavity portion 631 of sensor housing 630 by the light-emitting component 64a of sensor support housing 640 supportings.
Mode with the upper end of jam sensor support housing 640 is equipped with loam cake 650.Thus, sensor support housing 640 is positioned, and sensor support housing 640 is fixed on the sensor housing 630.Thus, light-emitting component 64a and photo detector 64b also are positioned.
The end face butt of the covering rinse bath 2 of the upper surface of loam cake 650 and housing 1a.Thus, each member of formation of turbidity detection portion 60 is fixed reliably.
As shown in Figure 6, for example the upper end of the fixedly washer jet 5 of Fig. 1～shown in Figure 3 is equipped with the turbidity of extending along vertical towards turbidity detection portion 60 and detects nozzle 5x.The inner space of turbidity detection nozzle 5x for example constitutes the part of the 3rd stream Rc shown in Figure 3.
As shown in Figure 6, the top ends of turbidity detection nozzle 5x is oriented to relative with the concavity portion 631 of sensor housing 630.Thus, be fed in rinse water under the situation of the 3rd stream Rc, rinse water detects nozzle 5x from turbidity and sprays continuously towards the top, and thus, rinse water is filled the inside of concavity portion 631.The rinse water of filling concavity portion 631 inside is detected the rinse water displacement of nozzle 5x ejection successively from turbidity.
Under this state, optical sensor 64 is driven.As mentioned above, sensor housing 630 has light transmission.So, the sidewall of the concavity portion 631 of the light transmission sensor housing 630 that is sent by light-emitting component 64a and be filled in rinse water in this concavity portion 631,64b is subjected to light by photo detector.
Thus, under the constant situation of the luminous quantity of light-emitting component 64a, the light income of photo detector 64b changes according to the dirty degree (muddy degree) that is filled in the rinse water in the concavity portion 631.Therefore, based on the magnitude of voltage of the detection signal of exporting from photo detector 64b, detect the turbidity of rinse water.In this case, the turbidity of rinse water is high more, and the light income of photo detector 64b is just more little, and is just low more from the magnitude of voltage of the detection signal of photo detector 64b output.
When rinse water was stopped the supply of the 3rd stream Rc, the rinse water that is filled in the concavity portion 631 was wandered the below along inner circumferential surface etc.
Feature to the turbidity detection portion 60 that constitutes as above makes the following instructions.
In the dish cleaning machine 1 of present embodiment, turbidity detection portion 60 is located at than the high position of peak level that accumulates in the rinse water in the portion of accumulating 12.
Thus, when rinse water was fed into stream Ra, Rb beyond the 3rd stream Rc, Rd, rinse water did not contact with the test section (concavity portion 631) of the turbidity of the rinse water of turbidity detection portion 60.In addition, when rinse bath 2 is discharged rinse water, rinse water does not remain in the test section (concavity portion 631) of turbidity of the rinse water of turbidity detection portion 60.
Therefore, can prevent that incrustation scale and wet goods are attached to the concavity portion 631 of sensor housing 630.Thus, reduce the detection error of the turbidity of rinse water, can detect the turbidity of rinse water for a long time exactly.In addition, also can be for example to be provided with on the surface of concavity portion 631 that the structure of sweeper etc. scrapes incrustation scale and wet goods.
In addition, turbidity detection portion 60 is located at the inside of rinse bath 2, safeguards easily.Thus, even under the dirty situation of concavity portion 631, the user also can easily get rid of this dirt.
As mentioned above, in turbidity detection portion 60, be ejected into the concavity portion 631 of sensor housing 630 from the rinse water of turbidity detection nozzle 5x.So, be filled in the inside of concavity portion 631 by rinse water, detect the turbidity of rinse water with optical sensor 64.
Here, turbidity detects nozzle 5x and disposes along vertical, and, concavity portion 631 is configured to relative with the top ends of turbidity detection nozzle 5x.Thus, the bottom 632 of concavity portion 631 is along the horizontal plane expansion and towards the below.Under such state, rinse water detects nozzle 5x when vertical is ejected into concavity portion 631 from turbidity, and the bottom 632 of concavity portion 631 is applied roughly hydraulic pressure uniformly.Thus, sneak in the rinse water that is imported into concavity portion 631 under the situation of bubble, this bubble is extruded downwards from concavity portion 631 equably by hydraulic pressure.Therefore, be ejected into constantly in rinse water under the situation of concavity portion 631, in concavity portion 631, gas phases such as bubble exist hardly.
In this case, owing in the rinse water that is directed between light-emitting component 64a and the photo detector 64b, do not have gas phase, so the detection error of rinse water turbidity reduces.
In addition, suppose to detect nozzle 5x, and the concavity portion 631 of sensor housing 630 is configured to relative with the top ends of turbidity detection nozzle 5x in along continuous straight runs configuration turbidity.In this state, when turbidity detected nozzle 5x and is ejected into concavity portion 631, because the influence of gravity, the hydraulic pressure that concavity portion 631 is applied along the bottom 632 of vertical was difficult to become evenly in rinse water.Therefore, sneak in the rinse water that is imported into concavity portion 631 under the situation of bubble, this bubble might move to upside in the inside of concavity portion 631 and be detained.
Therefore, preferred turbidity detects nozzle 5x and sensor housing 630 is configured to: detect nozzle 5x along vertical configuration turbidity, and with the top ends relative mode sensors configured housing 630 of concavity portion 631 with turbidity detection nozzle 5x.Thus, the detection error of turbidity is reduced as described above.
In addition, influence hardly at the bubble of sneaking into rinse water under the situation of detection error of turbidity, also can along continuous straight runs configuration turbidity detect nozzle 5x, and with the top ends relative mode sensors configured housing 630 of concavity portion 631 with turbidity detection nozzle 5x.In addition, can also make turbidity detect nozzle 5x with respect to the vertical tilted configuration, and with the top ends relative mode sensors configured housing 630 of concavity portion 631 with turbidity detection nozzle 5x.
Even in these cases, by turbidity detection portion 60 being located at the position higher than the peak level of the rinse water that accumulates in the portion of accumulating 12, when stream Ra, the Rb beyond rinse water is fed into the 3rd stream Rc, Rd, rinse water does not contact concavity portion 631 yet.In addition, by when rinse bath 2 is discharged, rinse water does not remain in the concavity portion 631 yet in rinse water.So, can prevent that incrustation scale, wet goods dirt are attached in the concavity portion 631 of sensor housing 630.
As mentioned above, the 16a of window portion of door 16 for example shown in Figure 2 has light transmission.Thus, under door 16 pent states, exterior light incides in the rinse bath 2 from the 16a of window portion.In this case, when detecting the turbidity of rinse water, might be because outside scattered light causes the accuracy of detection of optical sensor 64 to reduce.
To this, in turbidity detection portion 60, be used to detect the concavity portion 631 that the rinse water turbidity uses and center on by lower cover 610.As mentioned above, lower cover 610 constitutes the part of the end face of rinse bath 2, and this end face has light-proofness.
Thus, under the situation of rinse bath 2 inside, also can prevent that this light from entering in the concavity portion 631 of lower cover 610 inboards in incidence of external light under the door 16 pent states.Thus, when detecting the turbidity of rinse water, can prevent because outside scattered light causes the accuracy of detection of optical sensor 64 to reduce.
Inner surface in the concavity portion 631 of the sensor housing 630 of accepting rinse water has under the hydrophobic situation, when rinse water detects nozzle 5x when the water spray of concavity portion 631 finishes from turbidity, rinse water is as drop easily on the inner surface attached to concavity portion 631.Behind the droplet drying that is attached to concavity portion 631 inner surfaces, the dirt that is attached with drop unevenly and is contained at concavity portion 631 inner surfaces.At this moment, because concavity portion 631 inner surfaces are attached with dirt unevenly, so the turbidity that is detected by optical sensor 64 becomes unstable.
Therefore, preferably make the surperficial possess hydrophilic property of the concavity portion 631 that accepts rinse water of sensor housing 630.For example, cover hydrophilic resin at concavity portion 631 inner surfaces.In this case, can prevent to detect nozzle 5x from turbidity after the water spray of concavity portion 631 finishes in rinse water, rinse water is as drop and attached on concavity portion 631 inner surfaces.Thus, can prevent that concavity portion 631 inner surfaces are attached with dirt unevenly.Thus, can prevent when the detection of the turbidity of at every turn carrying out rinse water, reduce because of the drop that is attached to concavity portion 631 causes the accuracy of detection of turbidity.
In the present embodiment, in above-mentioned cleaning step and rinse step, detect the turbidity of the rinse water in the rinse bath 2 by the optical sensor 64 of turbidity detection portion 60.
Next with reference to Fig. 7, Fig. 8, the variation by the turbidity of optical sensor 64 detected rinse water is described.
Fig. 7 is that expression is from the magnitude of voltage of the detection signal of the optical sensor output of the dish cleaning machine of embodiments of the present invention 1 and the sequential chart (situation that the dirt that tableware adheres to is less) of rinse water variation of temperature.
As shown in Figure 7, at moment t
0～t

Next, as shown in figure 12, control part 70 beginning rinsings.By making the motor reverse rotation of pump 11, discharge the rinse water (S32) in the rinse bath 2.Next, control part 70 is supplied with the rinse water (S33) of ormal weight by the switching of control feed water valve 31a to the portion that accumulates 12 of rinse bath 2.
Next, control part 70 judges whether scavenging period is (S34) more than 40 minutes.Scavenging period is for example shown in Figure 7 from moment t
1To moment t
4Time, or for example shown in Figure 8 from moment t
11To moment t
17Time.At scavenging period is under the situation more than 40 minutes ("No" of S34), sets twice rinsings of 10 minutes (S35).
Scavenging period less than 40 minutes situation under ("Yes" of S34), judge whether scavenging period is (S36) more than 30 minutes.At scavenging period is under the situation more than 30 minutes ("No" of S36), sets twice rinsings of 7 minutes (S37).
Scavenging period less than 30 minutes situation under ("Yes" of S36), judge whether scavenging period is (S38) more than 20 minutes.At scavenging period is under the situation more than 20 minutes ("No" of S38), sets 1 time 10 minutes rinsing.In the situation (Yes of S38) of scavenging period, set 1 time 5 minutes rinsing (S39) less than 20 minutes.
Next, control part 70 begins to be cleaned the rinsing (S41) of thing 10.Particularly, control part 70 is rotated in the forward by the motor that makes pump 11, and rinse water is circulated in rinse bath 2, to being cleaned thing 10 continuous injection rinse water.Next, control part 70 has carried out finishing rinsing after the rinsing of the time that is set and number of times, enters next step.
For example shown in Figure 8, be attached with in stubbornness on the tableware under the situation such as more dirt, by improving the temperature of rinse water, and the cost scavenging period, dirt is dissolved in the rinse water gradually.Thus, can reduce along with effluxion from the magnitude of voltage of the detection signal TS of optical sensor 64, so scavenging period is elongated.In this case, the amount of dirt is more, so the rinsing number of times also increases, thus, the cleaning state of dirt also improves.
In addition, for example shown in Figure 7, be attached under the situations such as dirt on the tableware is less, dirt can be dissolved in the rinse water immediately.Thus, from the magnitude of voltage of the detection signal TS of optical sensor 64 can become immediately change little, so scavenging period shortens.In this case, the amount of dirt is less, so also can fully wash dirt even reduce the rinsing number of times.
As mentioned above, in the present embodiment, in cleaning step, the temperature that detects rinse water at temperature detecting part 17 reaches setting T, for example reach 52 ℃ after, proceed S minute, for example after 10 minutes the cleaning, detect the degree of fouling of rinse water by optical sensor 64.Decompose dirt, oil by the detergent ingredients that strengthens in the rinse water, the ability of protein and raising rinse water temperature, make dirt, rice grain and oil be soluble in rinse water, and can be by being attached to dirt, rice grain, the wet goods of the stubbornness on the tableware under the continuous sparging of rinse water.
Then, detect the turbidity of the rinse water of having dissolved dirt, cleaning step is finished by optical sensor 64.Thus, under the less situation of the dirt on the tableware, cleaning step for example shown in Figure 7 can make cleaning finish in the scavenging period of short time, can realize water saving, energy-conservation.In addition, under the more situation of the dirt on the tableware, cleaning step for example shown in Figure 8 by prolonging scavenging period, can wash the dirt, rice grain and the wet goods that are attached to the stubbornness on the tableware neatly.
Be set in the present embodiment: at magnitude of voltage V
(n-1)With V
nDifference ("Yes" of S26) under the situation below the 0.2V, finish to clean (S27), enter next step.Yet, magnitude of voltage V
(n-1)With V
nDifference may not be below 0.2V, the scope that detects voltage also can change according to the optical sensor that uses etc.In addition, contrast not according to variable quantity, can obtain same effect but for example contrast also according to rate of change, rate of change preferably is made as from 1 minute 2.5% to 10%.Particularly, for example, magnitude of voltage V in 1 minute detection time
(n-1)With V
nDifference below 0.4V (rate of change 10%), also can fully wash dirt.Variable quantity (rate of change) is more little, and the degree of cleaning is high more, if but be arranged in variable quantity (rate of change) within 1 minute less than 0.1V (2.5%), then can spend more scavenging period, power consumption also increases, therefore can't be energy-conservation.And if the rate of change of setting surpasses 10%, then probably can't obtain the effect that the present invention expects because of can't fully washing dirt.
In addition, in the present embodiment, be made as detection time 1 minute, detection time is preferably between 15 seconds～3 minutes.This is because if the time is too short, then variable quantity (rate of change) instability if the time is oversize, is then judged and made slowlyer.In addition, also can be set at detection time can be according to magnitude of voltage V
(n-1)With V
nThe numerical value of difference and variable.For example, if magnitude of voltage V
(n-1)With V
nDifference be 0.4V, then also can make detection time is 1 minute, if magnitude of voltage V
nWith V
(n+1)Difference be 0.2V, then also can make detection time is 30 seconds.Thus, can realize more energy-conservation effect.
In addition, in the present embodiment,, change the number of times and the time of rinsing according to scavenging period.By the processing of above-mentioned S34, S36, S38, it is less to be judged as dirt under scavenging period is situation below 20 minutes, thus the rinsing time also be set to short 5 minutes, and 1 rinsing to be enough to rinsing clean.Thus, can realize water saving, energy-conservation.Owing to be to set rinsing time and rinsing number of times corresponding to degree of fouling, so cleaning performance is better, that is, and when can realizing fully washing dirt, can clean tableware with optimal scavenging period, rinsing number of times and rinsing time, so can realize water saving and energy-conservation.
More than Shuo Ming scavenging period and rinsing number of times, rinsing time only are an example.Scavenging period is so long as by above-mentioned S34 for example, S36, and the order of S38 reduces to get final product.In addition, as described above, under the situation of scavenging period than length, increase rinsing number of times and rinsing time get final product, and under the short situation of scavenging period, minimizing rinsing number of times and rinsing time get final product.Thus, can clean, so can realize water saving, energy-conservation according to the degree that dirt on the tableware adheres to.
