The diapire face 220a of water storage tank 22 as a whole, the mode that reduces according to the past direction rear tilts, particularly, recess 227 inboard minimum.Bottom, back at this recess 227 is provided with outlet pipe 228 cylindraceous according to extending towards the mode of rear basic horizontal.This outlet pipe 228 is equivalent to aqueduct of the present invention, and is equivalent to the connection stream of water storage tank 22 sides.Because in this water storage tank 22, form water pipe 228 in the minimum position of diapire face 220a, so if being stored in the water level of water of the inside of water storage tank 22 reduces, then finally, water concentrates near the root of this outlet pipe 228, produces residual water hardly in the interior bottom portion of water storage tank 22.Thus, prevent when running finishes that the state that water retains in the inside of water storage tank 22 can avoid the water storage tank 22 of adhering to of incrustation scale etc. to be in the situation of antihygienic state.
In addition, water storage tank 22 can be made by synthetic resin, but in order to prevent adhering to of incrustation scale, keeps wholesomeness, can put into the resin of antiseptic such as employing.In addition, also can implement to form the such processing of antibiotic rete at the inner face of water storage tank 22.In addition, the front at least of water storage tank 22 is transparent or in the front of water storage tank 22 transparent window is set, so as the user easily by Visual Confirmation whether at the internal storage water of water storage tank 22.
Basic center top setting can be passed through the case bolt lock mechanism 28 of the pressing operation extraction of latched press-button 282 in the front of this water storage tank 22, if the user is received in case with water storage tank 22 and admits among the housing 2a, arrive the position of admitting fully, then automatically implement the breech lock of case bolt lock mechanism 28.On this case bolt lock mechanism 28, case latch switch 281 is set,, then can detects case latch switch 281 and open, implement the situation of breech lock if implement breech lock.When being in the state of the breech lock of implementing case bolt lock mechanism 28, even then under situation, do not remove breech lock yet such as the power that applies vibration etc., but, the user removes breech lock by pushing latched press-button 282, when pushing latched press-button 282, pulling water storage tank 22 is forwards to extract water storage tank 22 out.
When supply-water pump 24 is received among the case admittance housing 2a at water storage tank 22, be arranged at the position of the inboard that constitutes this recess 227.In this supply-water pump 24, the mode of extending to vertical lower according to motor reel 241 is provided with pump motor 240, in the bottom of this motor reel 241 impeller 242 is installed.Keeping between the top casing 243 and bottom enclosure 244 of pump motor 240, forming the pump chamber 245 of flat pattern, the bottom surface of the pump chamber 245 below impeller 242, suction inlet 246 openings according to the mode that centers on impeller 242.Like this, be flat pump chamber 245 flatly is set, suppress its height thus, thus, suppress the height of the integral body of supply-water pump 24, be receivable in the rear of water storage tank 22.In addition, in the space that is formed by top casing 243 and bottom enclosure 244, pump chamber 245 does not mediate, and is arranged at the position of the off-centre that enlarges in water supply uprise 251 sides described later.
Rear portion at suction line 248 forms the branched pipe cylindraceous 249 that extends vertically upward.Inside at this branched pipe 249, follow moving up and down of water level, the orbicule 250 that moves up and down is admitted as float of the present invention, inside at branched pipe 249, according to essentially identical height, illuminating part 261 and photographic department 262 constitutes a pair of optical sensor and is provided with as the case full water sensor 26 of water level detecting of the present invention mechanism.This case full water sensor 26 receives the light that penetrates from illuminating part 261 by photographic department 262, and the sensitization intensity that detects this light is below the threshold value of regulation.Promptly, water level in branched pipe 249 is lower, orbicule 250 is when lower position, and the light that penetrates from illuminating part 261 arrives photographic department 262, still, if water level rises, orbicule 250 rises to and illuminating part 261 essentially identical height, then can detect the light that penetrates from illuminating part 261 and be blocked no show photographic department 262 by orbicule 250, sensitization intensity sharply descends, and water level arrives this position.Here, this water level settings is at the full water water level L3 of water storage tank 22, and above-mentioned spilling water water level L2 is set in the position of a little higher than this full water water level L3.
If watch the inside of pump chamber 245, image pattern 6 and shown in Figure 7 then, according to keeping the mode in narrower gap with the periphery of impeller 242, from the top casing 243 vertical 243a of wall portion that establish, the position (breach 243b) that cuts off at the 243a of this wall portion is communicated with the chamber 245a that sends of broad, according to from being arranged at the outlet that this sends the end face of chamber 245a, the mode of Yan Shening is provided with water supply uprise 251 vertically upward.This supply-water pump 24 is a centrifugal pump, if by pump motor 240, impeller 242 drives along the prescribed direction rotation, and then impeller 242 is from middle the place ahead, that is,, it is pushed to the side with the good impetus suction waterborne at the suction inlet 246 of lower opening.This extruding is producing at impeller 242 in full week basically, but, major part around it is centered on by the above-mentioned wall 243a of portion, in addition, pump chamber 245 is arranged at the eccentric position that water supply uprise 251 enlarges, thus, the water by impeller 242 extruding concentrates on does not have the breach 243b of the 243a of wall portion place, sends chamber 245a with higher pressure inflow.In addition, with the inside of shifting water supply uprise 251 onto waterborne that flows into, be injected into the inside of cleaning chambers 3 through feed water inlet 29.
Because case full water sensor 26 is positioned at the upstream side of this pump chamber 245, in addition, the part of 245 stream branch has orbicule 250 from water storage tank 22 to pump chamber, so the load of the action of the impeller 242 that do not constitute supply-water pump 24 of moving up and down of this orbicule 250 does not hinder the attraction action of supply-water pump 24.
Inside be provided with supply-water pump 24 impeller 242 pump chamber 245 be wholy set in more lower position than the lowest part of the diapire face 220a of water storage tank 22.Therefore, even in the action by supply-water pump 24, specifically, the water in the spinning movement water storage tank 22 of impeller 242 flows out under the situation of suction line portion 247 fully, and water riddles pump chamber 245, and supply-water pump 24 can obtain fully high attraction power.Thus, supply-water pump 24 can substantially fully attract the water in the water storage tank 22, can prevent that the water of Xi Yining does not residue in the situation of the inner bottom part of water storage tank 22 when running finishes.In addition, because the height of dish cleaning machine 1 has restriction, so have the situation of insufficient height that case is admitted the space of the height of housing 2a, admittance water storage tank 22.In this occasion, be difficult to the lower position of lowest part of being wholy set in than the diapire face 220a of water storage tank 22 with pump chamber 245.But if the bottom of pump chamber 245 at least, that is, near the positions the suction inlet 246 be that then supply-water pump 24 can be brought into play higher attraction power than the low position of lowest part of the diapire face 220a of water storage tank 22, can attract the interior water of water storage tank 22.
If as described above, water storage tank 22 is received in the inside that case is admitted housing 2a, then outlet pipe 228 is intercalated in the inboard of suction line 248, water-stop is realized by sealing ring 229 in gap between the two, thus, the water of water storage tank 22 inside does not leak, and can be sent to pump chamber 245.On the other hand, forwards water storage tank 22 is being extracted out, when two pipes 228,248 broke away from, if not with the pipeline blockage of two pipes 228,248, the water that then is stored in water storage tank 22 inside flowed out respectively with the water of staying suction line 248 inside.Therefore, in two pipes 228,248 open and close valve 23,27 is set respectively, this open and close valve 23,27 is when both intercalations, and pipeline is open, when both break away from, apace with pipeline blockage.Because the structure of basic open and close valve is identical, so the structure of the open and close valve 23 of water storage tank 22 sides is described.
In the pipeline of outlet pipe 228, according to the negotiable mode of water, spring maintaining part 230 is extended from pipeline inner wall, passes the hole at the middle place that is opened in spring maintaining part 230, and shaft-like mobile 231 is according to installing along the axially movable mode of pipeline.The rear end of this mobile 231 constitutes the press section 231a that periphery enlarges, and between this press section 231a and spring maintaining part 230 helical spring 233 is set.Front end in mobile 231 is provided with stuffer 232, is used as valve seat around the pipeline of the root of outlet pipe 228.
The structure of the open and close valve 27 of supply-water pump 24 sides is identical, shown in the image pattern 8 like that, inside at suction line 248 is provided with spring maintaining part 270 according to the mode of stretching out from pipeline inner wall, and mobile 271, press section 271a, helical spring 273, stuffer 272 are provided with according to the mode identical with each building block of open and close valve 23.
Shown in the image pattern 8 (b) like that, at the state of admitting housing 2a forwards to extract out from case water storage tank 22, the mobile 231 of open and close valve 23 is not from the outside, specifically not from the rear side holding capacity, by the bias force that helical spring 233 will stretch, form mobile 231 and move to the state of rear position to greatest extent.Owing to the pipeline internal diameter of stuffer 232 greater than the root of outlet pipe 228, so the time, stuffer 232 fits tightly with the pipeline perisporium of the root of outlet pipe 228, with this pipeline sealing, prevents the situation that the water in the water storage tank 22 leak.The open and close valve 27 of supply-water pump 24 sides also is same, at the state that water storage tank 22 is forwards extracted out, mobile 271 is not from the outside, specifically from the front side holding capacity, by the bias force that helical spring 273 will stretch, form mobile 271 and move to the state of anterior position to greatest extent.Because stuffer 272 is greater than the pipeline internal diameter of the root of suction line 248, so prevent this moment stuffer 272, moves because of the water of the inside that residues in suction line 248 and last suction and stop, from the situation of the water leakage of water supply uprise 251 adverse currents with this pipeline sealing.
If the user pushes water storage tank 22, it is received in the inside that case is admitted housing 2a, then outlet pipe 228 inserts the inboard of suction lines 248, the press section 231a of the mobile 231 of the open and close valve 23 of water storage tank 22 sides contacts with the press section 271a of the mobile 271 of the open and close valve 27 of supply-water pump 24 sides, in the occasion that further is pressed into water storage tank 22 from here, the power of mobile 231,271 interacts, and helical spring 233,273 shrinks.Thus, the mobile 231 of water storage tank 22 sides moves towards horizontal the place ahead in outlet pipe 228, otherwise the mobile 271 of supply-water pump 24 sides moves towards horizontal rear in the inside of suction line 248.So stuffer 232 leaves with the pipeline perisporium (that is, valve seat) of the root of outlet pipe 228, water can pass through from its gap.On the other hand, stuffer 272 leaves with the pipeline perisporium (that is, valve seat) of the root of suction line 248, and water can pass through from its gap.In addition, if water storage tank 22 fully is received in assigned position, then shown in the image pattern 8 (a) like that, be in helical spring 233,272 at utmost to shrink, almost not have the state of elastic force, stuffer 232,272 fully leaves with valve seat respectively, water storage tank 22 is communicated with supply-water pump 24, and water freely passes through.
In addition, because when admitting water storage tank 22 as described above, in the both sides that are embedded in the recess 227 of supply-water pump 24 in loosening mode, water storage tank 22 is rearward outstanding, so this ledge is just realized the effect of guide, the horizontal action of restriction water storage tank 22.Thus, can suppress rocking of water storage tank 22, can substantially vertically water storage tank 22 rearward be pressed into.If when being pressed into water storage tank 22 along double swerve, then can't be with pipe 228,248 intercalations successfully, or promptly allow to intercalation still to manage 228,248, sealing ring 229 etc. applies compulsory load, but, in the dish cleaning machine of present embodiment, because as described above, rocking about water storage tank 22 is suppressed, so pipe 228,248 intercalations successfully can be realized certain connection.
In the dish cleaning machine of present embodiment, as described above, water storage tank 22 is received in the state that case is admitted housing 2a, running water retains in the inside of water storage tank 22, after cleaning running and dry operating, after running is finished, can extract water storage tank 22 out, open lid 222, inside is cleaned.Thus, the inside of water storage tank 22 is kept clean.
In the dish cleaning machine of present embodiment, relatively be assumed to the situation of maximum 10 (litre/minute) towards the supply capacity of the running water of water storage tank 22 by water supply hose 50, the water supply capacity of supply-water pump 24 is set at 12 (litre/minute).That is, the speed that is absorbed water on cleaning chambers 3 by supply-water pump 24 is higher than speed from running water to water storage tank 22 that supply with.Thus, at the state of supply-water pump 24 actions, even running water is being fed under the situation of water storage tank 22, the recruitment of the water in the relative water storage tank 22, reduction is more, like this, can guarantee that the water levels in the water storage tank 22 descend, and avoids water to fill with in the inside of water storage tank 22.
In addition, in the superincumbent description, owing to be used for that the too much water in the water storage tank 22 are discharged into the outer spilling water flexible pipe of machine 52 and be used for the scupper hose 19 that water is discharged to outside the machine from the inside of cleaning chambers 3 is provided with fully individually, so 2 scupper hoses must be set to kitchen basin 62 places, but also can converge, derive the scheme distortion of 1 flexible pipe according to inside or both streams of outside at shell 2.According to this scheme, owing to the draining flexible pipe that extends to kitchen basin 62 from this dish cleaning machine 1 is 1, so outward appearance is good, the complexity of the setting of flexible pipe also alleviates, and the free degree that is provided with of this dish cleaning machine 1 also increases.
Structure to the control system of the dish cleaning machine of present embodiment is described below.Figure 10 is the electrical system architecture figure of major part of the dish cleaning machine of present embodiment.
Basic step when below the running in the dish cleaning machine 1 of present embodiment being begun preceding water supply describes.Figure 12 and Figure 13 are for being illustrated in when water storage tank 22 water fillings flow chart of the basic procedure of operation that the user carried out and the action of this machine.
At first, original state is that mains cord is connected with the commercial ac power supply socket, and the state of power supply disconnection.In this dish cleaning machine 1, when such power supply disconnected, display part 7b extinguished fully, the user looks that power supply disconnects fully, but in fact can be with the microcomputer of drive current supply control part 30, such as, the signal of receiving magazine full water sensor 26 grades carries out predetermined process.
From power-off state as described above, user's pushing power switch 71 is connected power supply (step S1).Then, select required stroke, such as (step S2) such as standard stroke, a small amount of stroke, fast travels by stroke options button 73.Then, user's tap switching bolt (step S3) of 63 of fetching boiling water.So, by water supply hose 50, running water being begun to supply with water storage tank 22, it remains in the inside of this water storage tank 22.Follow the rising of the water level in this water storage tank 22, the orbicule 250 of case full water sensor 26 also float, if arrival full water water level L3, then case full water sensor 26 react (at step S4, being "Yes").The reaction of control part 30 receiving magazine full water sensors 26 makes supply-water pump 24 actions (step S5).Thus, supply-water pump 24 with being pressed onto feed water inlet 29 on it, remains in the inside of cleaning chambers 3 with it by water supply uprise 251 by the storage of water in the attraction of the connecting portion between above-mentioned outlet pipe 228 and the suction line 248 water storage tank 22.
Because as described above, according to standard mode, the attraction speed of supply-water pump 24 is greater than the speed in the running water inflow water storage tank 22, so even under the situation that the water filling to water storage tank 22 continues, the water levels in the water storage tank 22 reduce at leisure.On the other hand, the water level in the cleaning chambers 3 rises at leisure, and level sensor 20 monitors this water level in the chamber.Then, if the water level that control part 30 by the detection signal of level sensor 20 in the chamber, detects in the cleaning chambers 3 arrives the cleaning water level L1 (at step S6, being "Yes") that stipulates, then stop the action (step S7) of supply-water pump 24.Thus, the water level rising in the cleaning chambers 3 stops.At the moment, the water level in the water storage tank 22 is lower than full water water level L3, still, and owing to supply-water pump 24 stops, so the water levels in the water storage tank 22 begin to rise once more.Then, if arrive full water water level L3 because case full water sensor 26 reacts (at step S8, being "Yes") once more, so the time control part 30 carry out filled with water circular (step S9).Specifically, drive buzzer 7c according to the mode of sending the buzzing sound of determining as the full water circular, the running of lighting display part 7b monitors the water filling/full water display lamp of display part 76.
The user who notices the full water circular stops water (step S10) by closing the switching bolt of tap 63.Thus, the water filling to the inside of water storage tank 22 stops, and the rising of water level stops.In addition, after being the full water circular of step S9, the user does not close the occasion of tap 63 at once, shown in the dotted line in the image pattern 12 like that, water level in water storage tank 22 is crossed the stage of spilling water water level L2, by overflow pipe 225 and spilling water flexible pipe 52, the water in the water storage tank 22 begins to discharge (step S13) outside machine.Therefore, if spilling water flexible pipe 52 suitably is set, then the water level in the water storage tank 22 is no more than spilling water water level L2.The user pushes beginning key 72, so that entry into service (step S11) after closing the switching bolt of tap 63.Control part 30 receives this operation, begins common running.
On the other hand, consider that from power-off state as described above, the user is pushing power switch 71 not, that is, and in the fetch boiling water occasion of tap 63 of power-off state.Tap 63 (the step S21) if the user fetches boiling water, then by water supply hose 50, running water begins to supply with water storage tank 22, remains in the inside of water storage tank 22.Even under the situation of power-off state, still Dong Zuo control part 30 can't detect the beginning of this water supply, still, at ordinary times, watch box full water sensor 26 whether react (step S22).Thus, if the water level in the water storage tank 22 rises, arrive full water water level L3, case full water sensor 26 is reacted (at step S22, being "Yes"), then this situation is discerned, and S9 is identical with above-mentioned steps, carries out full water circular (step S23).Therefore, if the user notices this full water circular, close tap 63, thus, stop to supply water (step S24), then the water level rising in the water storage tank 22 stops.On the other hand, postpone if close tap, then the generation of the outflow of the water by spilling water flexible pipe 52 as described above.In addition, wait at this state then, until pushing power switch 71 (step S25).
In this occasion, that is, do not have to connect and to the occasion of water storage tank 22 water fillings at power supply, because different during with power connection, supply-water pump 24 is failure to actuate, Gu Shui does not feed to the inside of cleaning chambers 3.Therefore, the occasion in that the power connection state supplies water retains the water that arrives cleaning water level L1 in the inside of cleaning chambers 3, and retains the water that arrives full water water level L3 in the inside of water storage tank 22.On the other hand, in the occasion that power-off state supplies water, only retain the water that arrives full water water level L3 in the inside of water storage tank 22.In the present embodiment, because the water yield of the full water water level L3 of water storage tank 22 is about 6 liters, the water yield of the cleaning water level of the inside of cleaning chambers 3 is about 3 liters, so when power connection, store about 9 liters water on the whole, when power supply disconnects, store 6 liters water on the whole.
In addition, if after step S9 or S23 carry out the full water circular, be in the state that tap 63 is opened, then as described above, the above water of spilling water water level L2 should be discharged to outside the machine by overflow pipe 225 and spilling water flexible pipe 52, but, spilling water flexible pipe 52 suitably is not set having, or overflow pipe 225 stops up, the occasion of the fault of draining etc. suitably, if water storage tank 22 filled with water, then water further rises in the inside of water supply uprise 251 from the pump chamber 245 of supply-water pump 24, enters and remains in the inside of cleaning chambers 3.In addition, if the water level in the cleaning chambers 3 rises, arrive and be set in the anomalous sea level that is higher than the position of cleaning water level L1, then 20 pairs of these situations of level sensor detect in the chamber, and control part 30 makes draining pump 132 actions.Thus, water begins to discharge outside machine from the inside of cleaning chambers 3, can prevent that the water level in the cleaning chambers 3 from rising to more than the anomalous sea level.Thus, can prevent from never to realize fully that the gap etc. of the bottom door 5 of water-stop is located, water spills into the outer situation of machine in large quantities.
Below according to Figure 14～Figure 19, at the action of foregoing description, to being that more concrete description is carried out in the action of this dish cleaning machine 1 at center with control part 30.At first, the situation that the mains cord of this dish cleaning machine 1 is extracted out from commercial AC Power supply socket is considered as original state.That is, not above-mentioned power-off state, but electric power is not supplied with the state of this machine fully.At this moment, obviously, be included in control part 30 and stop in interior whole actions.If from this state, the user inserts mains cord in the commercial ac power supply socket, then supplies with to control part 30 and drives electric power, carries out initial setting (step S30).Occasion established standards stroke at this initial setting.
Then, control part 30 judgements are to connect power supply by the operation of power switch 71, otherwise still, (step S32) cuts off the electricity supply, in the occasion that is power-off state, shown in the image pattern 15 like that, implement the processing (step S52) that the display lamp with display part 7b extinguishes fully, then, judge case full water sensor 26 whether react (step S54).In the occasion that case full water sensor 26 is reacted, as described above, can suppose in power-off state, the user fetch boiling water the tap 63, to the situation of water storage tank 22 water fillings.Therefore, control part 30 is notified the full water circular (step S56) of water storage tank 22 filled with water, then by the demonstration of display part 7b and the action that pipes of buzzer 7c, according to the detection signal of level sensor in the chamber 20, judge whether the water level in the cleaning chambers 3 is anomalous sea level (step S58).
Even as described above, behind the full water circular, tap 63 is not closed yet, and the discharge of the water by spilling water flexible pipe 52 occasion of suitably not carrying out, and water retains in the inside of cleaning chambers 3, arrives anomalous sea level.Therefore, be judged to be the occasion of anomalous sea level at step S58, make draining pump 132 actions by load drive division 32, from cleaning chambers 3 drainings (step S60), circulate a notice of to turn back to step S58 by the demonstration of display part 7b and the action that pipes of buzzer 7c at anomalous sea level (step S62).Then, judge it is not the occasion of anomalous sea level, or be to remove after the action of draining pump 132 occasion of anomalous sea level, stop the action (step S64) of draining pump 132, turn back to step S32 at step S58.On the other hand, be step S54, under the situation that case full water sensor 26 is not reacted, still turn back to step S32 at this state.
If judge that at step S32 power switch 71 connects, then control part 30 replaces the standard stroke set by initial setting, and sets the stroke (step S34) when going up secondary source and disconnecting.Such as, be last time, carry out the running of a small amount of stroke, the occasion that power supply disconnects is set a small amount of stroke at step S34.Then, stop this action (step S36), judge whether case latch switch 281 connects (step S38) in the occasion of carrying out case full water circular.In the occasion that case latch switch 281 disconnects, because suitably being received in case, do not admit among the housing 2a decidable water storage tank 22, so by the demonstration of display part 7b and the action that pipes of buzzer 7c, the admittance mistake (step S50) of circular water storage tank 22.
Be the occasion that step S38 case latch switch 281 is connected, admit among the housing 2a, so then judge case full water sensor 26 whether react (step S40) because water storage tank 22 suitably is received in case.Such as, are empty occasions in water storage tank 22 inside, because case full water sensor 26 is not reacted, so control part 30 judges whether the operation by stroke options button 73, carry out travel settings input (step S42),, set the stroke of having imported (step S44) in the occasion that the stroke input is arranged.Such as, set a small amount of stroke at step S34, then in occasion, set from a small amount of stroke at step S44 by stroke options button 73 choice criteria strokes, become the standard stroke.Then, judge whether beginning key 72 has been pressed (step S46), even still do not receive under the situation of having pushed, by the action that pipes of display part 7b and buzzer 7c, circular operation invalid (step S48) turns back to step S32.
If as described above, at the power connection state, the user opens tap 63, and beginning is to water storage tank 22 water fillings, and then water begins to retain in the inside of water storage tank 22.But,,, during this period,, still do not accept this operation, not entry into service even the user pushes beginning key 72 so carry out the processing of step S32～S48 repeatedly because before arriving full water water level L3, S40 is judged to be "No" in step.In addition, if the water level in the water storage tank 22 arrives full water water level L3, then case full water sensor 26 is reacted, and forwards step S66 shown in Figure 16 to from step S40, judges whether carve the stroke of setting at this moment is a small amount of stroke.
Here, simply the content of each stroke is described.The standard stroke adopts 9 liters water generally, adopts the cleaning 1 time of washing agent, adopts 3 times the running of rinsing (comprising heating rinsing described later) of the common water that does not comprise washing agent.A small amount of stroke adopts 6 liters the water of being as general as that is less than the standard stroke, cleans 2 times running of rinsing (comprising the heating rinsing) 1 time.Fast travel is identical with the standard stroke, adopts 9 liters water generally, but identical with a small amount of stroke, carries out peace and quiet 1 time, and 2 times running of rinsing (comprising the heating rinsing) is so that save time.In this occasion, because the rinsing number of times is few, so the water yield during rinsing is more than the standard stroke.
Be judged to be the occasion of a small amount of stroke at step S66, because as described above, original makes water consumption few, so before the private water supply of cleaning chambers 3, stop to water storage tank 22 water fillings.For this reason, control part 30 is circulated a notice of water storage tank 22 filled with water (step S80) at once by the demonstration of display part 7b and the action that pipes of buzzer 7c.
On the other hand, the occasion of the stroke beyond a small amount of stroke, such as, in the occasion of standard stroke, fast travel, carry out step S66～step S68, make supply-water pump 24 actions by load drive division 32.Thus, the water in the water storage tank 22 begins to attract by supply-water pump 24, supplies to the inside of cleaning chambers 3.Then, judge whether to have pushed beginning key 72 (step S70), in the occasion of pushing, S48 is identical with above-mentioned steps, operates invalid circular (step S74).That is, do not accept to begin key 72 equally at this moment quarter.In addition,, judge whether the water level in the cleaning chambers 3 arrives cleaning water level L1 (step S72), before arriving cleaning water level L1, turn back to step S68 by level sensor in the chamber 20.
In addition, the action of supply-water pump 24 disconnects under the irrelevant situation in the connection with door switch 33 and carrying out.That is, even under the situation of opening door 4,5, still carry out from the water supply action of water storage tank 22 to cleaning chambers 3.Thus, though the user for tableware being admitted the inside of cleaning chambers 3, open door 4,5 during situation under, still can be to the private water supply of cleaning chambers 3, avoid non-situation of wishing that ground the prolongs duration of runs.
If during step S68～S72 repeatedly, the water level of the inside of cleaning chambers 3 arrives and cleans water level L1, then stops the action (step S76) of supply-water pump 24, stops the private water supply to cleaning chambers 3.Because as described above, carve at this moment, water level in the water storage tank 22 is lower than full water water level L3, so before case full water sensor 26 is reacted, keep this state (step S78), if follow the water level in the water filling water storage tank 22 of water storage tank 22 to rise, case full water sensor 26 is reacted, and is then identical with above-mentioned steps S56, circular water storage tank 22 filled with water (step S80).As mentioned above, if the circular by filled with water, the user closes tap 63, and then the water filling to water storage tank 22 stops, and in the water storage tank 22, is in the state of the water yield of storing full water water level L3 substantially.
In processing by step S66～S80, the stroke of having set is the occasion of a small amount of stroke, inside at cleaning chambers 3 does not have water, near the inside of water storage tank 22 retains arrival full water water level L3 water, the occasion of the stroke of other beyond a small amount of stroke, be in the inside that the water that arrives cleaning water level L1 is stored in cleaning chambers 3, and near the state of the water the internal storage arrival full water water level L3 of water storage tank 22.That is, the occasion beyond a small amount of stroke is in the about 6 liters water of the internal storage of water storage tank 22, at the about 3 liters water of the internal storage of cleaning chambers 3, stores the state of 9 liters water altogether.On the other hand,, be in the inside of water storage tank 22, still store the state of about 6 liters water in the occasion that is a small amount of stroke.But, this state refers to be step S40, before case full water sensor 26 is reacted, carry out the occasion of the setting of a small amount of stroke, even begin action from supply-water pump 24 after, the user selects by stroke options button 73 under the situation of a small amount of stroke, and supplying water does not stop yet, and the water of the water yield identical with other stroke of standard stroke etc. is stored in the inside of cleaning chambers 3.
Usually, by the full water circular of step S80, the user notices filled with water, closes tap 63, then, pushes 72 entrys into service of beginning key.Control part 30 judges whether to push beginning key 72 (step S82), and in the occasion of pushing, the detection signal by door switch 33 judges whether to close door 4,5 (step S84).In the occasion of closing door 4,5, stop full water circular (step S86).Then, the stroke that sets is the occasion (at step S88, being "Yes") of a small amount of stroke,, makes supply-water pump 24 actions here, attracts the storage of water in the water storage tank 22, and it is supplied to the inside (step S90) of cleaning chambers 3.When step S84 decision gate 4,5 is not closed, notify door 4,5 circulars of opening (step S92), turn back to step S82.
If judge at step S82 and not push beginning key 72, then shown in the image pattern 17 like that, judge according to the detection signal of level sensor in the chamber 20 whether cleaning chambers 3 interior water levels are anomalous sea level (step S94).Its reason be not according to press off the beginning key 72 occasion, the possibility height that tap 63 is not closed yet, the possibility that is in anomalous sea level in the cleaning chambers 3 is higher.Be judged to be the occasion of anomalous sea level at step S94, make draining pump 132 actions (step S96) apace, and be in anomalous sea level (step S98), turn back to step S94 by the demonstration of display part 7b and the action circular that pipes of buzzer 7c.On the other hand, after the action that is not anomalous sea level or draining pump 132, eliminate the occasion of anomalous sea level, stop draining pump 132 (step S100), turn back to step S82.
Judge when being not a small amount of stroke at step S88, and as a small amount of stroke, at step S90 after cleaning chambers 3 supplies water, shown in the image pattern 18 like that, clean running and rinsing turn round (step S102) according to the running program of the stroke of having set.That is, make scavenging pump 131 action, attract to retain in the water of the bottom of cleaning chambers 3, from water spray-hole 10 towards the tableware injection water.
In this running, control part 30 confirm repeatedly on-stream whether have unusual.That is, at first, control part 30 judges by level sensor in the chamber 20 whether the water level in the cleaning chambers 3 is anomalous sea level (step S104), if not anomalous sea level, judges then then whether case latch switch 281 connects (step S106).Suitably admitting water storage tank 22, the occasion that case latch switch 281 is connected then judges whether to produce supply water unusual (step S108).Such as, when being in the state that makes supply-water pump 24 action, the occasion more than the specified degree that do not rise at the appointed time of the water level cleaning chambers 3 in is judged to be and supplies water unusually.
If judge the generation of supplying water unusually also, judge then whether regulation cleaning and the rinsing running according to running program finishes (step S110) at step S108.Final rinsing operates as the heating rinsing of the water that adopts high temperature, still, in the occasion of its end, then carries out residual water and handles action (step S111).In the moment that rinsing running finishes, the water in the water storage tank 22 should all use and not residual basically, still, in turning round the way the user, add and supply with the such occasion of water, have in rinsing and turn round the finish time, in the possibility of the inside of water storage tank 22 residual water.Therefore, handle action, chien shih supply-water pump 24 and draining pump 132 actions in the time of according to the rules as residual water, thus, even under the situation in water residues in water storage tank 22, this water temporarily rises in the inside of cleaning chambers 3, discharge outside machine from here, thus, the inside that can make water storage tank 22 is hollow.In addition, in residual water is handled, temporary transient internal feed water to cleaning chambers 3, thus, have spray when supplying water and be spread across danger on the tableware, still, because not after the dry operating but after the rinsing running finishes, carry out residual water and handle action, even so still can make the tableware drying under the situation of watering flower, can be not dry final processing of the tableware of dry operating do not impacted by the dry operating of next time.
After above-mentioned residual water is handled action, carry out dry operating (step S112), if dry operating finishes the running tenth skill of then stipulating (step S113) according to the regulation of running program, the circular running finishes (step S114), turns back to step S32.In addition, finish back automatic power cut-off circuit operation,,, then automatically carry out power supply and disconnect action if through the stipulated time even the power supply opening operation of pushing power switch 71 does not carry out in running.But, even as described above, under the situation of power-off state, will drive current supply control part 30, be in substantial operating state.
