The open communique of Japan 2002-336175 application for a patent for invention

Summary of the invention

But, use washing agent to spend time owing to distinguishing ground, so the user extremely expects to provide the dish-washing machine that can use general kitchen detergent.

The objective of the invention is at dish-washing machine, solve such problem.

The dish-washing machine of the present invention that is used to solve above-mentioned problem has running and carries out mechanism, this running is carried out mechanism and is carried out the kitchen detergent program, in this kitchen detergent program, employing is mixed with the washings of general kitchen detergent, and in the foaming that the inhibition general kitchen detergent causes, the tableware that is accommodated in the purge chamber is washed.

According to this scheme, in dish-washing machine,, tableware to be washed owing to can adopt general kitchen detergent, the time that spends so eliminate the user to use general kitchen detergent and special purpose detergent, ease of use is good with distinguishing.

As more concrete scheme, best, in described dish-washing machine, this running is carried out mechanism and is comprised washing pump, and this washing pump is used for inhaling being stored on the washings of inside of above-mentioned purge chamber, and it is showered on the tableware; Controlling organization, this controlling organization is controlled this washing pump;

Above-mentioned controlling organization is mixed with in the washing stroke of washings of general kitchen detergent in employing, according to turning round action and be longer than the mode that stops to move that this running is moved repeatedly, above-mentioned washing pump is controlled, and carries out sprinkle and intermittently washs.

In this scheme, in the running action of washing pump, washings are showered on the tableware, the dirt on the tableware is come off.At this moment,, be easy to generate foaming largely, still, because then, be longer than the action that stops of this running action, so the foaming that produces diminishes at this stopping period because of the influence of general kitchen detergent.Obviously, at this stopping period, in the action of passing through formerly, the washings that are showered on the tableware are penetrated in the dirt that is attached on the tableware, easily dirt are peeled off.In addition, best from suppressing the aspect of foaming, the time of running action is the several seconds.In addition, from can further reducing the aspect of foam, the time that stops to move is tens of seconds, for being longer than the running time of actuation time greatly.

According to this scheme, owing to can when suppressing foaming, tableware be washed, so can realize to use general kitchen detergent the dish-washing machine that tableware is washed.

In addition, in dish-washing machine of the present invention, best following formation, promptly, it comprises the heating arrangements that the washings to the inside that is stored in the purge chamber heat, setting is lower than the ceiling temperature of protein coagulated temperature, and above-mentioned controlling organization is in above-mentioned washing stroke, according to the mode of the setting temperature that is no more than protein, by above-mentioned heating arrangements, washings are heated, simultaneously, carry out sprinkle and intermittently wash.

Promptly, even under the low situation of the temperature of washings, still come off easily at the protein dirt that is attached on the tableware, as common washing, make the constantly occasion of action of washing pump continuously, even when washings are heated, under the situation of washing, still can be low in the temperature of washings during, remove this protein dirt.But, in the above-mentioned washing stroke that adopts general kitchen detergent, intermittently wash owing to have the long sprinkle that stops to move, so protein can not drop apace.Thus, if when washings are heated, it is washed, then have protein do not drop during, the danger that the temperature of washings rises.

Therefore, in such scheme, owing to pass through to when arriving ceiling temperature, the mode that is no more than this ceiling temperature according to temperature is controlled heating arrangements, when not rising to protein coagulated temperature, carry out sprinkle and intermittently wash,, can prevent that scourability from reducing so can prevent the situation that protein solidifies.

Also have, in scheme of the present invention, best, as described below constitute like that, that is, and after carrying out above-mentioned washing stroke, discharge is mixed with the washings of general kitchen detergent, store new water, carry out the 2nd washing stroke, simultaneously in the 2nd washing stroke, above-mentioned controlling organization passes through heating arrangements, washings are heated to above the 2nd ceiling temperature of above-mentioned ceiling temperature, simultaneously, above-mentioned washing pump are moved.

Greasy dirt, starch dirt are difficult to drop at low temperatures, but, in this programme, because after carrying out above-mentioned washing stroke, carry out the 2nd washing stroke, in the 2nd washing stroke, in tableware, the washings of sprinkle high temperature, even so according to not solidifying at protein under the situation that the mode of carrying out washing stroke under such low temperature constitutes, greasy dirt, starch dirt are come off, and scourability is good

In addition, in the 2nd washing stroke, because the water in the replacement purge chamber, so general kitchen detergent is significantly diluted.So, best, in the 2nd washing stroke, do not carry out sprinkle and intermittently wash, and continuous or make the washing pump action near continuum of states, so that wash according to the intensity bigger than washing stroke.

Also have, as more concrete scheme, in described dish-washing machine, best, resemble and constitute as described below, promptly, above-mentioned operation is carried out mechanism and is comprised washing pump, inhales on the washings that this washing pump is used for being stored in the above-mentioned purge chamber, and it is showered on the tableware; Bubble testing agency, this bubble testing agency is used to detect the foamed state in the above-mentioned purge chamber; Controlling organization, this controlling organization is mixed with in the washing stroke of washings of general kitchen detergent in employing, and is corresponding to the detected foamed state of above-mentioned bubble testing agency, and above-mentioned washing pump is controlled;

Above-mentioned controlling organization shortens the actuation time of above-mentioned washing pump when foaming degree is big, or makes above-mentioned washing pump action with more weak degree, and tableware is washed.

In this scheme, such as, make the washing pump action in the early stage, detect the foaming in the purge chamber at this moment.In the bigger occasion of foaming degree, if washing pump is moved for a long time, or, then have the inside of foam from the purge chamber with strong degree action, leak into the outer danger of machine.On the other hand, foaming is subjected to the influence of the dirt state of tableware, and the dirt of tableware is few more, and the dirt of washings is few more, and then foaming degree is big more.So, the bigger occasion of foaming in judging the purge chamber, though since few at dirt, need not still can judge under the situation of bigger washing force, so relatively shorten the actuation time of washing pump.Perhaps, reducing under the situation of the voltage added etc., washing pump is rotated with more weak degree.

If like this, adopt this scheme, because by the foamed state in the corresponding purge chamber, washing pump is controlled, can be when suppressing foaming, provide the washing force of the dirt of corresponding tableware, so, still can wash tableware fully even under the situation of the bigger general kitchen detergent of foaming degree.So, can realize adopting general kitchen detergent the dish-washing machine that tableware is washed.

Have, as more concrete scheme, in described dish-washing machine, as described below constituting, that is, above-mentioned running is carried out mechanism and is comprised water supply mechanism again, and this water supply mechanism is used for the private water supply to above-mentioned purge chamber; Drainage mechanism, this drainage mechanism are used for water is discharged in above-mentioned purge chamber; Bubble testing agency, this bubble testing agency is used to detect the foamed state in the above-mentioned purge chamber; Controlling organization, this controlling organization is mixed with in the washing stroke of washings of general kitchen detergent in employing, corresponding to the detected foamed state of above-mentioned bubble testing agency, above-mentioned water supply mechanism and drainage mechanism are controlled, replace the water in the above-mentioned purge chamber, the general kitchen detergent in the washings is diluted;

Best, above-mentioned controlling organization is according to when foaming degree is big, and the mode that increases the replacement amount of above-mentioned water constitutes.

In this scheme, detect the foamed state in the purge chamber, according to the corresponding amount of this foamed state, the water in the replacement purge chamber dilutes washings.That is, in the bigger occasion of foaming degree, relatively increase the replacement amount of washings, largely general kitchen detergent is diluted.Like this, the foaming in the time of can suppressing the washing pump action.

If like this, adopt this programme, because foamed state by corresponding purge chamber, adjust the dilute strength of washings, when suppressing foaming, provide and the corresponding washing force of the dirt of tableware, so even under the situation that adopts general kitchen detergent, still can wash tableware fully.So, can realize adopting general kitchen detergent the dish-washing machine that tableware is washed.

In addition, also such scheme can be made up.In this occasion, can when suppressing foaming on the whole, obtain clean result, such as, bigger at foaming degree, will wash water-reducible occasion largely, also can have the situation that does not relatively shorten the actuation time of washing pump.The situation that also can have in contrast, the actuation time that relatively prolongs washing pump.

Below the effect of dish-washing machine is summarized.

According to this dish-washing machine, even use general kitchen detergent, still can be in the foaming that suppresses its generation, carry out the corresponding washing of dirt situation with tableware, so can realize adopting general kitchen detergent the dish-washing machine that tableware is washed.Therefore, the time that spends less than distinguish general kitchen detergent and special purpose detergent when the user uses, ease of use is good.

In addition, because in the 1st washing stroke, because according to the mode of action that stops to move " sprinkle intermittently washs 1 " and " sprinkle intermittently washs 2 " that constitute of carrying out by running action repeatedly and being longer than that this running moves, control washing the draining pump 12 of holding concurrently, even so under the situation of using general kitchen detergent, still can when suppressing foaming, tableware be washed fully.

In addition, because during the initial operation in the 1st washing stroke, detect the foaming in the purge chamber 2, according to this foaming result, judge foamed state (the dirt situation of tableware), to should foamed state, be adjusted at the action frequency of " sprinkle intermittently washs 2 " of next total running, promptly, adjust washing and hold concurrently the actuation time of draining pump 12, so can in the foaming that suppresses purge chamber 2, provide and the corresponding washing force of the dirt of tableware, even under the situation of using general kitchen detergent, still can fully wash to tableware.

Also have, during owing to the initial operation in the 1st washing stroke, detect the foaming in the purge chamber 2, according to this testing result, judge foamed state (the dirt situation of tableware), corresponding foamed state dilutes washings, washings by dilution, always turn round, so can when suppressing foaming, provide and the corresponding washing force of the dirt of this tableware, even under the situation that adopts general kitchen detergent, still can wash tableware fully.

Have again, in the 1st washing stroke, setting is lower than the ceiling temperature of protein coagulated temperature, and the mode according to the setting temperature that is no more than protein heats washings, simultaneously, carry out sprinkle and intermittently wash, so, make apace under the situation that protein comes off even can not intermittently wash in order to carry out sprinkle, still can prevent protein coagulated situation, prevent the reduction of scourability.

In addition, because behind the 1st washing stroke, carry out the 2nd washing stroke, simultaneously, in the 2nd washing stroke, washings are heated to above the 2nd ceiling temperature of ceiling temperature, even so under the situation that the mode of carrying out the 1st washing stroke under the noncondensing low temperature according to protein constitutes, still in the 2nd washing stroke, greasy dirt, starch dirt are come off well, scourability is good.

In addition, the installation site of optical sensor 27, promptly, the bubble detection line that detects foaming is lower than the front openings bottom (spilling water line) as the purge chamber 2 at the position with foam internal leakage of 2 from the purge chamber, even so under the bigger situation of foaming degree, can prevent the situation of foam internal leakage of 2 from the purge chamber.

Also have, the level sensor 26 of the water level of the inside of detection purge chamber 2 is the type of pressure sensor, in the past, if the level sensor of widely used float type is subjected to the influence of foam in dish-washing machine, then be easy to generate misoperation, relative with this situation, owing to occasion in the adopts pressure sensor type, be difficult to influence because of foam, produce misoperation, thus general kitchen detergent can be adopted, even at the state that allows foam to a certain degree, still can wash, correctly sensed water level.

Above-mentioned dish-washing machine is characterised in that to have the employing general kitchen detergent, and to the kitchen detergent program that tableware washs, the control action to this kitchen detergent program is described below.Fig. 6 is the flow chart of the flow process of the stroke of expression kitchen detergent program.

The user is accommodated in tableware in the tableware cage 5, opens door 3,4, and tableware cage 5 is accommodated in the purge chamber 2.Then, an amount of general kitchen detergent is put into the inside of purge chamber 2, close door 3,4, then, push kitchen detergent program key 185.Control part 20 receives this operation, opens the washing running of kitchen detergent program.After the running beginning, at first, adopt the washings that are mixed with general kitchen detergent, realize the 1st washing stroke (being equivalent to washing stroke of the present invention) (step S1).In the 1st washing stroke, realize repeatedly in short time that to tableware spray washing water place the action of the time of being longer than this spray time, spray is intermittently washing.Then, change the water in the purge chamber 2, adopt to be blended in residual slightly washings washing agent, that concentration is extremely low after the draining of the 1st washing stroke, carry out the 2nd washing procedure (step S2).Then, (step S3～S5) is so that wash the washings that are attached on the tableware off to carry out 3 times the stroke that washs.In addition, adopt the heating of the hot water of high temperature to wash stroke (step S6), so that carry out sterilization, and by tableware being heated the drying efficiency during raising drying next time.At last, carry out, supply with the dry trip (step S7) that adds hot-air to the inside of purge chamber 2.If the dry operating time of regulation finishes, then finish whole strokes.

For in this kitchen detergent program, the 1st washing stroke and the 2nd washing stroke of characteristics arranged, with reference to the flow chart of Fig. 7 and Fig. 8, and expression follows Fig. 9 of the curve map that the water temperature of the carrying out of stroke changes, and its detailed action is described.

Control flow chart when Fig. 7 is the 1st washing stroke.If the 1st washing stroke is begun, then control part 20 is opened feed water valve 28, and supply water in 2 inside in the purge chamber, if by level sensor 26, detects the situation that arrives predetermined water level, then stops to supply water (step ST1).Then, pump motor 120 is moved as the washing pump motor, simultaneously, begin heater 16 is switched on, beginning initial operation (step ST2).The washings that are stored in the purge chamber 2 are heated, and by nozzle arm 6, the washings that force feed has heated spray these washings from water jet nozzle 7, and it is showered on the tableware.This initial operation is to be used for tableware being carried out detect the running of the foamed state (pollution condition of tableware) in the purge chamber 2 when sprinkle intermittently washs.

In this initial operation, intermittently wash in order to carry out sprinkle, it is 12 times that pump motor 120 makes maximum numbers of occurrence of the action of " sprinkle intermittently washs 1 ".In the action of this " sprinkle intermittently washs 1 ", carry out repeatedly realizing for 5 times that 0.2 second work (on)-1 second stops the intermittent running (running action) of the strong running of (off), then, carry out that running stops between 30 seconds (stopping action).

By the intermittent running of strong running,,, the dirt that is attached on the tableware is come off to tableware sprinkle washings with the short period.At this moment, because general kitchen detergent foams easily, so even under the situation of the running of short period, still generation foaming to a certain degree.This foaming long during continuous 30 seconds stop to move during less.

Input amount in general kitchen detergent is certain occasion, and the foaming in the purge chamber 2 depend on the pollution condition of the washings that the dirt degree of tableware causes.That is, in the more occasion of the dirt of tableware, foaming degree is little, and in the less occasion of the dirt of tableware, it is big that foaming degree becomes.Thus, medium at the dirt of tableware, the occasion of less state, in the process of the action of carrying out " sprinkle intermittently washs 1 " repeatedly, foaming degree increases.

At this baseline,, monitor whether foam arrives bubble detection line (step ST3) termly by optical sensor 27.If in initial operation, by optical sensor 27, detect foam and arrive the bubble detection line, then control part 20 stops the action of pump motor 120 and the action of heater 16, finishes initial operation (step ST4).Control part 20 judges in initial operation, the action frequency of " sprinkle intermittently washs 1 " whether at 5 times with interior (step ST5).Then,, judge that then the foam in the purge chamber 2 is bigger if in 5 times, in addition, the dirt of tableware few (step ST6).If more than 5 times, then foaming degree is medium.In addition, judge the dirt medium (step ST7) of tableware.

On the other hand,, arrive the action of the state-detection " sprinkle intermittently washs 1 " of bubble detection line at foam if carry out by optical sensor 27 for 12 times repeatedly, then control part 20 finish initial operation (step ST8, ST9).In this occasion, control part 20 judges that foaming degree is little, in addition, and the dirt of tableware many (step ST10).

Then, control part 20 always turns round, and still, owing to before this, at total running, suppress foaming, carries out simultaneously and the corresponding washing running of the dirt state of tableware, so as required, washings is diluted (reduction detergent concentration).Thus, the corresponding foamed state of having judged (the dirt state of tableware) is determined the replacement amount of the water in the purge chamber 2, that is, and and the water discharge time (step ST11) of decision replacement amount.That is, in foaming degree big (dirt be'ss few) occasion, water discharge time is 60 seconds.At foaming degree is the occasion of medium (the dirt degree is medium), and water discharge time is 30 seconds.In the occasion of foaming degree less (dirt is more), water discharge time is 0 second (no draining).The water discharge time of control part 20 to determine like this makes pump motor 120 as the draining pump motor action, and in purge chamber 2, draining is supplied water, once more until predetermined water level (step ST12).In addition, be 60 seconds occasion at water discharge time, most washing agent is discharged in 2 inside from the purge chamber.Thus, in the washings of storing next time, exist in draining after, residue in the detergent amount in the storehouse slightly, washings are diluted significantly.So, according to half concentration of original washings, with the washings dilution of storing next time.Obviously, in the few occasion of foaming degree, carry out draining, water supply.

If like this, be adjusted at the concentration of employed washings in total running, then always turn round.In the occasion of total running, intermittently wash in order to carry out sprinkle, pump motor 120 according to the corresponding action frequency of foamed state, carry out the action of " sprinkle intermittently washs 2 " repeatedly.In the action of this " sprinkle intermittently washs 2 ", carry out repeatedly realizing for 5 times that 0.2 second work (on)-1 second stops the intermittent running of the strong running of (off), then, carry out 4.5 seconds work (on) the continuous running (intermittent running with continuously running constitute the running action) of weak running, then, carry out running in 30 seconds and stop (stopping action).

At first, control part 20 corresponding foamed states (the dirt state of tableware) are determined the action frequency (step ST13) of the action of " sprinkle intermittently washs 2 ", and in the foaming degree occasion of big (dirt is few), action frequency is 10 times.At foaming degree is the occasion of medium (the dirt degree is medium), and in foaming degree little (dirt be'ss many) occasion, action frequency is 12 times.Then, control part 20 makes pump motor 120 move as the washing pump motor, begins simultaneously heater 16 energisings, the total running of beginning (step ST14).

By the intermittent running and the continuous running that is right after its weak running of strong running, to be longer than the time of initial operation sprinkle washings on tableware.Thus, washings are not showered on the tableware with having omission, the dirt that is attached on the tableware are had with omitting do not drop.At this moment, though corresponding to the dirt situation, washings are diluted,, because above-mentioned intermittent running and running continuously with to a certain degree, are foamed.Yet this foaming degree diminishes at the stopping period of 30 seconds following length.

If like this,, carry out " sprinkle intermittently washs 2 " according to pre-determined action frequency, then control part 20 stops the action of pump motor 120 and the action of heater 16, finish always to turn round (step ST15, ST16).Like this, in total running, corresponding foamed state, if it is bigger according to foaming degree, the mode that concentration reduces, washings are diluted, according to the mode of the action of carrying out " sprinkle intermittently washs 2 ", control washing the draining pump 12 of holding concurrently, in this occasion, by corresponding foamed state, if foaming degree is bigger, can shorten the actuation time (reducing the action frequency of " sprinkle intermittently washs 2 ") of the double draining pump 12 of washing, thus, when can suppress the foaming in the purge chamber 2, carry out and the corresponding washing running of the dirt of tableware.In addition, in this dish-washing machine, when foaming degree is medium with hour, action frequency is identical, the effect of the dilution when its reason is that foaming degree is medium is bigger, and number of times is reduced.Promptly, in the two occasion of the control of the action frequency of control of diluting washings and change " sprinkle intermittently washs 2 ", can be when suppressing foaming on the whole, carry out and the corresponding washing of the dirt of tableware, also can be according to the dilute strength of washings, resemble so above-mentionedly, action frequency is identical or opposite.In addition, also can corresponding foamed state, do not change the hold concurrently action frequency of draining pump 12 of washing, change work (on) time, work (on) time of running continuously of intermittent running of the action of " sprinkle intermittently washs 2 ", thus, can change the actuation time of the double draining pump 12 of washing.In addition, also can not change washing and hold concurrently the actuation time of draining pump 12, and change the intensity of washing double draining pump 12, that is, and number of revolutions.In addition, in total running,, then suppress to reduce and interrupt the washing running, the washing of further the diluting washings processing of foam of number of revolutions etc. of draining pump 12 of holding concurrently if detect the situation that foam arrives the bubble detection line.

If like this, finish running always, then control part 20 moves pump motor 120 as draining pump, and the washings in the purge chamber 2 are discharged to machine outer (step ST17).Like this, the 1st washing stroke finishes.

In addition, in the 1st washing stroke, set the ceiling temperature of the washings that heated.This ceiling temperature is the temperature that is lower than the temperature that protein begins to solidify, such as 40 ℃.In addition, in initial operation and total running,, detect the temperature of washings by temperature sensor 25, when control part 20 is 40 ℃ in the temperature arrival of judging washings, the heater 16 that can keep this ceiling temperature is carried out open and close controls (with reference to the curve map of Fig. 9).

Control flow chart when Fig. 8 is the 2nd washing stroke.If begin the 2nd washing stroke, then control part 20 is opened feed water valve 28, supplies water in purge chamber 2, until reaching predetermined water level (step S11).In purge chamber 2, store and be mixed with pastel washings washing agent residual slightly after the 1st washing stroke draining, that concentration is extremely low.Then, make pump motor 120 as the washing pump motor action, hydraulic pressure is delivered in the nozzle arm 6, from water jet nozzle 7, injection water begins the washing running.At this moment, the rotary speed of pump motor 120 is set at the 2300rpm of weak running.In addition, simultaneously, begin heater 16 is switched on, begin the water that is stored in the purge chamber 2 is heated (step S12).

Control part 20 detects the temperature that retains in the water in the purge chamber 2 by temperature sensor 25, judges repeatedly whether water temperature arrives 40 ℃ (step S13).If water temperature reaches 40 ℃, then control part 20 from weak running, becomes the 2700rpm (step S14) of strong running with the rotary speed of pump motor 120.Then, keep 1 minute (step S15) of strong running, then, after through 1 minute,, become weak running (step S16) from strong running.Even because in during 1 minute strong running, make the heating of water of heater 16 continuous, so water temperature rises at leisure.Because during 1 minute strong running, the rotary speed of pump motor 120 rises, so relatively increase from the flow of water of the water of water jet nozzle 7 injections.Behind the 1st washing stroke, even the dirt of residual protein class still can be washed off at this.

Then, control part 20 judges repeatedly whether the detected temperatures of temperature sensor 25 reaches 50 ℃.If water temperature reaches 50 ℃, then identical with above-mentioned steps S14～S16, control part 20 is once more with the rotary speed of pump motor 120, from weak running, become strong running (step S18), keep 1 minute (step S19) of strong running, after through 1 minute, it from strong running, is become weak running (step S20).Animal raw fat almost solidifies at normal temperatures, but since the fusing point of butter in 35～55 ℃ scope, the fusing point of lard is in 28～48 ℃ scope, so near 50 ℃, a large amount of animal raw fat like this liquefies, and comes off easily.Therefore, when water temperature arrives 50 ℃, switch to strong running, thus, the effect that can expect to make the dirt of such animal raw fat class to come off.

Then, control part 20 judges repeatedly whether the detected temperatures of temperature sensor 25 reaches 58 ℃ of the 2nd ceiling temperatures (step S21).If water temperature reaches 58 ℃, then control part 20 is controlled (step S22) according to making temperature keep certain mode to heater 16, and the rotary speed of pump motor 120 once more from weak running, is become strong running (step S23).Then, keep 1 minute (step S24) of running by force, after through 1 minute, become weak running (step S25) from strong running.In addition, keep 3 minutes (step S26) of weak running, after through 3 minutes,, become strong running (step S27), keep 1 minute (step S28) of strong running in addition from weak running.Under 58 ℃ water temperature, with the stronger flow of water,, thus, the starch based that residues on the tableware class, the dirt of grease class are peeled off from the tableware class to each tableware class injection water, it is washed off.

Then, at step S28, after through 1 minute, the heating of heater 16 is stopped (step S29), and stop pump motor 120 (step S30).Then, this time, pump motor 120 is moved as draining pump, the water that is stored in the purge chamber 2 is discharged to outside the machine.

Like this, in the 2nd washing stroke, set the 2nd ceiling temperature, and the 2nd ceiling temperature is the temperature that is higher than the ceiling temperature of the 1st washing stroke, such as 58 ℃.So, can the dirt of starch based, the dirt of oils fully be dropped at the 2nd washing stroke.In addition, in the 2nd washing stroke, because the concentration of washings is minimum, so, carry out still not having the danger of foaming under the situation that sprinkle intermittently washs even not as the 1st washing stroke.

Above one embodiment of the present of invention are described, still the invention is not restricted to the content of the foregoing description, can in the scope of claims record, carry out various conversion.
