Description
Technical field
The present invention relates to be used to operate the method for dish-washing machine, described dish-washing machine comprises the circulating pump that is used to hold the washing bucket of article to be cleaned and is used for the cleaning solution in the wash cycles bucket, and at user option a plurality of cleaning procedure wherein is provided, and described cleaning procedure comprises a series of continuous process of selecting in water inlet, prerinse, cleaning, rinsing, immersion, draining and oven dry process (step).
Background technology
In the dish-washing machine in modern times, the user can select in a plurality of cleaning procedures usually, and described a plurality of cleaning procedures are because of its operating temperature, duration, water consumption and the selection and the order of process differ from one another continuously.
Therefore, in the dish-washing machine selection of typical cleaning procedure be included in standardization program that 65 ℃ cleaning temperature for example carries out down, under 50 ℃ more low temperature for example, carry out wash course energy-conservation program, for example carrying out the powerful cleaning procedure of wash course and the quick circulation that can be used in particular for cleaning glass under 70 ℃ the higher temperature, wherein use shorter clean cycle and for example 40 ℃ carry out down.In in these cleaning procedures each, for example being fed to the water yield in the dish-washing machine and the independent operation parameters such as duration of independent process can be fixed.In addition, dish-washing machine can comprise automatic mode, wherein selects cleaning procedure automatically based on detected some parameter of the sensor that provides in the dish-washing machine, and described parameter is for example for cleaning load (that is, the amount of article to be cleaned and type) and amount of contaminants.
Though the cleaning procedure in the current dish-washing machine is more and more being optimized aspect water consumption and the power consumption, be desirably in the dish-washing machine performance in this area all the time and use simple and easy aspect that further improvement is provided.
Summary of the invention
The object of the present invention is to provide the method that is used to operate dish-washing machine, reduce the noise of dish-washing machine operating period generation by this method.Especially, though in modern dish-washing machine, the noise level that circulates the process machine by cleaning fluid during operation and caused by the operation of circulating pump has been reduced to by sound insulation and has been lower than the conventional noise level that domestic households stands, but still the silent mode operation dish-washing machine that expectation can further be reduced with the noise level that the operation dish-washing machine produces, particularly at night.Therefore, though domestic households is measured to the sound pressure level of 40-41dB by day usually, traditional dish-washing machine operates in the sound pressure level of 39-40dB usually.Though for day time operation, this may be enough because the operation noise of dish-washing machine is sneaked in the background noise and thereby do not discovered, at indoor and street noise less night, the noise that is caused by the operation of dish-washing machine becomes puzzlement usually.
Therefore, the objective of the invention is to design a kind of method that is used to operate the dish-washing machine that the operation noise that reduces is provided.
In the method that is used for operating dish-washing machine, described dish-washing machine comprises the circulating pump that is used to hold the washing bucket of article to be cleaned and is used for the cleaning solution in the wash cycles bucket, and wherein provide at user option a plurality of cleaning procedure, described cleaning procedure comprises from injecting, prerinse, clean, rinsing, soak, the a series of continuous process of selecting in draining and the oven dry process, the reason that the present invention solves described purpose is that cleaning procedure further comprises first cleaning procedure and second cleaning procedure, in described first cleaning procedure, circulating pump is operated with normal speed, in at least a portion of described second cleaning procedure, the speed operation of circulating pump to reduce with respect to normal speed, and at least one immersion process is provided between not on-stream period of circulating pump.
As used herein, the term of circulating pump " normal speed " expression circulating pump is in the speed of the routine operation manipulate of dish-washing machine, and during the standard cleaning program promptly known in the art and wherein the speed of circulating pump is mainly selected based on the amount that realizes the cleaning solution that satisfied cleaning result is required and pressure.All in the dish-washing machine with single speed operation, this single standard speed therefore represented in term " normal speed " to circulating pump during whole conventional cleaning procedures.If circulating pump is designed at least some conventional cleaning procedures with more than a speed operation, for example to operate with the higher second speed of the powerful cleaning procedure of higher rate arrival article to be cleaned corresponding to first speed operation of the single speed of above-mentioned standard and to be used for cleaning solution, then any one in these standard speeds represented in term " normal speed ", for the situation of single speed pump, similarly this speed is mainly selected based on the amount of the required cleaning solution of the cleaning result who realizes expectation and pressure.
Though in traditional dish-washing machine, noise reduces all to be realized by mechanical device, better sound insulation for example is provided, but the present invention is based on the idea of the speed that in fact reduces circulating pump, therefore described circulating pump also only stands ON/OFF control with single speed operation in traditional dish-washing machine.Because therefore the reduction that reduces to cause cleaning efficiency of the service speed of circulating pump need measure this reduction with the compensation cleaning efficiency.According to the present invention, reducing of the service speed of circulating pump by comprising that in program sequencing at least one immersion process becomes possibility, described immersion process is during this period the article to be cleaned in dish-washing machine by the process of at first soaking with cleaning solution, so the operation suspension of dish-washing machine, promptly cycle circulation pump regular hour and cleaning fluid are allowed to be dipped in the dirt that remove from article to be cleaned.
Though advise reducing the sound levels of dish-washing machine in the prior art by the prolongation cleaning procedure, utilize the fact of sound levels thus based on sound power measurement (being the acoustic energy of unit interval), but the invention provides a kind of operator scheme of dish-washing machine, wherein the peak noise level that experiences in the operating period of dish-washing machine is lowered.The present invention provides real " silent mode " thus, and wherein sound levels and the acoustic pressure that is produced by dish-washing machine all is reduced.Measurement has shown that the operation noise of dish-washing machine can reduce about 2-3dB by using the method for this paper suggestion.Therefore, use the method for this paper suggestion, dish-washing machine can operate in the noise level of about 36-38dB.
The preferred embodiments of the present invention limit in the dependent claims.
Especially, in described second cleaning procedure, circulating pump can and be preferably 90% speed operation less than normal speed with the speed in the 85%-95% scope of normal speed.Therefore, if during can being any one first cleaning procedure in the conventional cleaning procedure, circulating pump is with the speed operation of for example 1800rpm, and then in described second cleaning procedure, the speed of circulating pump can be reduced to 1600rpm under the situation of not damaging wash result.Similarly, if dish-washing machine is (wherein circulating pump is with the speed operation of for example 2400rpm) during being designed to first cleaning procedure of powerful care program, find that then the speed of circulating pump can be reduced to 2200rpm under the situation of not damaging wash result by the immersion process is provided in second cleaning procedure.
In order under the situation of the clean-up performance that does not damage dish-washing machine, to reduce the speed of circulating pump, the cycle of clean cycle is determined, in this cycle, immersion process or immersion suspend and have improved wash result effectively and enabled the similar at least even better wash result with the speed that the reduces acquisition of circulating pump thus.
Provide therein in the clean cycle of prerinse process and find, wherein the water of heating does not circulate in washing bucket, if provide the immersion process will obtain good especially result after the prerinse process, during described immersion process, circulating pump does not turn round.Advantageously, immersion process after the prerinse process has at least 15 minutes duration, is preferably at least 20 minutes, wherein similarly, the prerinse process is preferably the duration that had at least 10 minutes, and more preferably has at least 15 minutes duration.
For the ease of discharging in the spot particulate self-cleaning article, dissolve detergent in the water that can during the prerinse process, in washing bucket, circulate.By the immersion process of the water that utilization do not heat is provided after the prerinse process finishes, then the spot particulate is with unusual Energy Efficient with have cost-benefit mode thus by effectively removal from article-cleaning.
In the optimum definite process regularly that is used for providing the immersion process, find that further the immersion process can also be included in the wash course very effectively, in described wash course, the cleaning solution of heating is sprayed on the article to be cleaned.In this wash course, during the first of wash course, provide heat usually to cleaning solution, this warms cleaning solution, is not circulating in washing bucket under cleaning solution provides the situation of additional heat afterwards.Should be appreciated that wash course is not limited to this Temperature Distribution (profile) but can be included in before described first and second parts, afterwards or other parts therebetween, during this period, the cleaning solution of heating or not heating circulates in washing bucket.
Very effective a kind of timing is found to be in the decline of wash course or after wash course for the immersion process.During wash course, most dirt particulate of usually being soaked and soaking during the prerinse process are dissolved and remove from article-cleaning.Except chemistry that plays a role during the wash course and mechanical cleaning, the removal of some the dirt types such as dirt particulate after for example amyloid dirt particulate or the baking needs more time.Can provide this extra time that is used for dissolving obstinate dirt and therefore obtaining satisfied wash result in a wash course (one of them of wash course) the second immersion process afterwards.This immersion process after described wash course is preferably the duration that had at least 15 minutes, and more preferably has at least 20 minutes duration.Though this immersion process after described wash course is called as " the second immersion process " in this article, should be appreciated that this optional immersion process can be applied to prerinse process immersion process afterwards extraly or replacedly.
Substitute the single immersion process after a wash course, the described second immersion process can also be included in that (being during cleaning solution warms) provides during the first of described wash course first soak suspend and during the second portion of described wash course, provide second soak and suspend, during the second portion of described wash course, cleaning solution circulates in washing bucket under the situation of extra heating that is not provided it.The immersion time-out that provides in wash course is divided into first and soaks under the situation of the time-out and the second immersion time-out, and this immersion time-out is preferably the duration with 5-15 minute, and is most preferably about 10 minutes.
Especially when in cleaning fluid, using when comprising the cleaning agent of enzyme, if find wash course after or at the immersion time-out that carries out subsequently during the wash course under 40 ℃-45 ℃ temperature and most preferably under about 42 ℃ temperature, carry out, then effective.
Especially, when use comprises the detergent of enzyme in cleaning solution, if except during to cleaning solution provide heat first and during cleaning solution the second portion that in washing bucket, circulates under the situation that additional heat is not provided (promptly during cleaning solution circulating under the state of cooling), the temperature of cleaning solution was held constant third part during wash course also was included in, be preferably and remain on the enzyme temperature, for between 40 ℃ and 45 ℃ and be preferably about 42 ℃, the behavior of then cleaning can further be improved in most cases.Though soaking interval, the circulating pump in the dish-washing machine and therefore the spray arm in the dish-washing machine do not turn round, keep constant heating interval in the temperature of this cleaning solution, circulating pump and therefore spray arm can turn round.
Be used to provide the 3rd preferred time interval of soaking time-out before the rinsing process, described rinsing process constitutes the last process in the clean cycle usually.During the rinsing process, clear water is sprayed on the article-cleaning, thereby washes loosening dirt particulate and any remaining detergent off.During the rinsing process, article-cleaning also is heated to higher temperature, and for example 70 ℃, thus when being drained (drain), the loop termination of cleaning solution and washing bucket provide from the oven dry effect.
Be provided at therein in the clean cycle of the middle rinsing process between wash course and the final rinsing process, described immersion process can play a role during the middle rinsing process or when middle rinsing process finishes.This final immersion process can also provide after middle rinsing process finishes, and promptly the water on being sprayed to article-cleaning (being preferably cold clear water) provides after being drained from washing bucket.
Though the described immersion process before the rinsing process is preferably the duration that had at least 20 minutes, when having about 30 minutes duration, this immersion process realizes optimum.
Though above immersion process can replacedly be used, but realize best wash result, i.e. the 3rd immersion process before second immersion process during immersion process during the prerinse process, the wash course and the rinsing process when soaking processes using whole three kinds.
Can reduce by the noise that can realize with the speed operation circulating pump lower than normal speed during the part of clean cycle at least can be by further being reduced with the burst mode operation circulating pump, promptly by changing continuously the speed of pump, the user is produced less sound imperssion of bothering because find the operation noise that produces during with the burst mode operation circulating pump.In addition, though should be appreciated that owing to soak time-out, whole clean cycle is than not existing the situation of soaking time-out to have the longer duration, but this prolongation of clean cycle is not harmful under many circumstances, in any case because, dish-washing machine often operates in the time of clean cycle needs often and compares the situation with more pot lifes, for example, when operating in night or operate in the user, dish-washing machine leaves home work and daytime of just returning for a long time that will be after cleaning procedure stops.
Though realized that actual noise reduces when circulating pump only makes its part operation carry out with the speed that reduces, circulating pump is preferably with the speed operation that reduces with respect to normal speed in whole second cleaning procedure.

Fig. 3 is the schematic diagram that is used for the replaceable program circuit of the dish-washing machine of operation according to the present invention.
The specific embodiment
Fig. 1 shows the example of a cleaning procedure, and it can be used for traditional dish-washing machine equally.This cleaning procedure generally includes the prerinse process, and article wherein to be cleaned stand to be used for to remove coarse dirt particulate and the initial clean process of the spot can be easily removed from article-cleaning.After this prerinse process, under the temperature that is higher than the temperature of in the prerinse process, using, carry out main wash course usually, wherein during main wash course, more obstinate dirt particulate is become flexible equally and is removed from article-cleaning.After main wash course, article-cleaning is exposed to cold rinsing process, and during cold rinsing process, loosening spot particulate and detergent are washed off from article-cleaning.In final hot rinsing process, the clear water of heating is sprayed on the article-cleaning and provides heat with described article-cleaning of abundant cleaning and while to article-cleaning, and this heat is used to dry article-cleaning.
In the illustrated examples of this cleaning procedure of describing as Fig. 1, the prerinse process starts from the draining subprocess, and during the draining subprocess, draining pump is activated, thereby removes any liquid in the collecting-tank that accumulates in dish-washing machine in clean cycle before.After draining pump is activated the regular hour amount or until there not being further liquid from the collecting-tank of dish-washing machine, to be discharged, clear water is fed in the dish-washing machine and circulating pump is activated, thereby presenting these water therefore also is sprayed onto these water on the article to be cleaned to rotatable spray arm, described article to be cleaned are placed on the tableware rack in the purge chamber that is provided at dish-washing machine usually, for example descend tableware rack and last tableware rack.The prerinse process can be carried out (i.e. water temperature to have during from tap that dish-washing machine was connected when water) with cold water or carry out (with heated water during the recirculation during being fed to clean container or in clean container) with hot water, perhaps by using hot and cold water to carry out successively.Preferably, prerinse process is carried out under the temperature between 15 ℃ to 55 ℃.
During the prerinse process, detergent can be added in the water that in dish-washing machine, circulates, the detergent container that this detergent can flow by the detergent distributor, with cleaning solution or by using the multicompartment detergent to be added in the cleaning solution, described multicompartment detergent provides with the block form that comprises a plurality of activating agents, and described block is dissolved in the cleaning solution with the different time during clean cycle.In the latter stage of prerinse process, draining pump is activated, thereby removes any spot particulate that dissolves in cleaning solution and the self-cleaning article.
After the prerinse process, carry out main wash course, during this main wash course, the cleaning solution that warms circulates in dish-washing machine, promptly at first clear water be fed in the washing bucket and afterwards circulating pump be activated, thereby will be collected in that water in the collecting-tank of dish-washing machine is fed to that the position is furnished with under the tableware rack of article to be cleaned thereon or on spray arm, thereby cleaning solution is sprayed onto on the article-cleaning.During main wash course, cleaning solution is heated to the temperature in 30 ℃ of-70 ℃ of scopes usually.
Cleaning solution is sprayed onto reach regular hour amount on the article-cleaning after, circulating pump is by deexcitation and comprise the detergent of the dissolving of washing off now and the cleaning solution of dirt and spot particulate is discharged from the collecting-tank of dish-washing machine by activating draining pump from article-cleaning.
After main wash course, clean cycle comprises a plurality of rinsing processes, and during described rinsing process, water is fed in the dish-washing machine and circulating pump is operated, thereby rinsing is from remaining spot particulate and detergent in the article to be cleaned.Though in the water that is fed to dish-washing machine, do not adding detergent usually during the rinsing process, but especially, in initial rinsing process, some detergents may reside in the cleaning solution, for example when may be during prerinse and the main wash course not consoluet multicompartment cleaning block of use.In addition, some further inorganic agents can be added in the cleaning solution, and this can realize for example specific glass treatment agent etc. by using the multicompartment cleaning block equally.
Though initial rinsing process is carried out with for example 30 ℃-40 ℃ low temperature usually, during final rinsing process, use for example 35 ℃-70 ℃ higher temperature, thereby heating is convenient to the oven dry of article-cleaning thus by the article-cleaning of rinsing.In the latter stage of each rinsing process, can be by activating draining pump emptying collecting-tank.
Should note cleaning procedure arbitrarily independently process can comprise several subprocess, for example be divided into the main wash course of a plurality of wash phases of carrying out with different temperatures.In this case, the cleaning solution that uses in clean container can be by activating draining pump and when second stage begins clear water being fed in the clean container and exchanging between this seed stage based on the termination of phase I.
During above-mentioned whole processes, circulating pump can single speed operation, thereby certain hydraulic pressure is provided, and by this hydraulic pressure, cleaning solution is sprayed on the article to be cleaned.Yet if expectation as the higher hydraulic pressure that can use the article (plate that for example has the dirt that adheres to the baking on it) of cleaning severe contamination, dish-washing machine can be designed as with more speed operation cycle pump.Yet, because higher hydraulic pressure may cause the damage of some article such as meticulous glassware for example, therefore during clean cycle arbitrarily to the use of the more speed of circulating pump and corresponding higher hydraulic pressure all should be only specific request by the user activate, for example by selecting " powerful nursing " program etc.
Fig. 2 shows cleaning procedure, it comprises and similar program process shown in Fig. 1, but wherein providing some to soak suspends, soak interval at this, circulating pump do not turn round and time of should immersions time-out being used for providing extra so that cleaning solution be dipped in the dirt particulate that is attached to article to be cleaned with any activating agent that adds cleaning solution to.
Though in the example shown in Fig. 2, soak in each this process of suspending after being inserted into the subprocess that is draining washing bucket the latter stage of prerinse process, main wash course and cold rinsing process, soak and suspend and before draining dish-washing machine, to use.In any case, immersion process or immersion suspend the duration that have a few minutes, be preferably between 5-30 minute, thereby the time that allows abundance provide sufficient immersion.Suspend by using to soak, cleaning efficiency is enhanced circulating pump can be with the degree of low-speed handing, and this correspondingly provides lower pressure, and under this pressure, cleaning solution is sprayed on the article that place in the dish-washing machine.In this way, average noise level and the reality that causes by the operation of dish-washing machine and moment noise level all be lowered.Though use the immersion process obviously to cause the prolongation of comprehensive cleaning procedure, but this prolongation, does not promptly influence when dish-washing machine has much affect or do not have by water filling and in the starting in night and when just drawn off the next morning at all in night time operation at dish-washing machine.
In dish-washing machine as this paper suggestion, therefore the user of dish-washing machine can select between a plurality of or " routine " cleaning procedure, for example as different temperatures such as 40 ℃, 50 ℃ or 65 ℃ under auto-programming or the standardization program carried out, the powerful cleaning procedure of under 70 ℃ higher temperature for example, carrying out, or have the rapid cleaning program of the program duration of shortening.To whole these programs general be circulating pump can be identical in whole cleaning procedures in operation and this normal speed under the optimized normal speed according to cleaning efficiency.Except these programs, the user can also select silent mode, wherein at least a portion of program separately and preferably for whole procedure, the speed operation of circulating pump to reduce with respect to described normal speed, and wherein provide at least one immersion process, during this immersion process, circulating pump does not turn round.
Fig. 3 shows the part of the main wash course of the change that can use as shown in Figure 2 in comprehensive cleaning procedure.Especially, Fig. 3 shows the main wash course that comprises some subs, described sub i.e. the first main wash phase and the second main wash phase, during the first main wash phase, temperature is that about 30 ℃-45 ℃ cleaning solution that warms slightly is sprayed on the article to be cleaned, and during the second main wash phase, cleaning solution is warmed to roughly 40 ℃-70 ℃ higher temperature.
