In addition, show in the present embodiment the example that is provided with a Washing spray nozzle 7 in the bottom of sink 2, but also two Washing spray nozzles can be set correspondingly with the shape of sink 2, and can use non-rotary fixed nozzle.In addition, in washing section 18, be arranged in the way of circulating path (not shown) to the washings pressurization and to the washing pump 8 of the supply washings such as Washing spray nozzle 7 and the motor 9 of driving washing pump 8, this circulating path is arranged at the outside, bottom surface of sink 2.
In addition, accumulate the reservoir 10 of washings and heater (heating part) 11 that washings are heated is arranged on bottom near the peristome 5 the sink 2.The thermistor (temperature detecting part) 13 that detects the temperature of washings is arranged on the outer wall of the bottom surface of sink 2, indirectly detects the temperature of the air in washings or the sink 2 across the diapire of sink 2.The water level detection switch 14 that the water level of the washings of the bottom that accumulates in sink 2 is detected is arranged on the outer wall of the bottom of sink 2.In addition, the water unit 15 that supplies water in the sink 2 is installed in the outer wall on the top of sink 2.
Be provided in control part 16 control water unit 15, heater 11 and the washing pumps 8 of the bottom of the main body 1 between main body 1 and the sink 2, and carry out according to this heating efficiency estimating step, washing step, rinse step, heating rinse step and this series of steps of drying steps of tableware 3.And 16 pairs of signals that detected by water level detection switch 14, thermistor 13 of control part are processed, and according to the tableware capacity of being judged by the temperature of thermistor 13 detected washings in the sink 2.
Below, with reference to Fig. 1 on one side utilize Fig. 2 ~ Fig. 4 to as described above action and the effect of the dish cleaning machine of the present embodiment of formation describe on one side.Fig. 2 is the flow chart of action of the dish cleaning machine of explanation embodiments of the present invention 1.Fig. 3 is employed synoptic diagram when the tableware capacity of the dish cleaning machine of estimating embodiments of the present invention 1.Fig. 4 is the figure of relation that is illustrated in the time tk of the arrival temperature T k of the tableware capacity that estimates in the dish cleaning machine of embodiments of the present invention 1 and heating rinse step and drying steps.
At first, as shown in Figure 2, be placed in tableware 3 washings such as grade on the plate-basket 4 and be received in the sink 2, after the user drops into washing agent, utilize door body 6 with peristome 5 sealing and the entrys into service of sink 2.
Then, control part 16 moves water unit 15, is utilizing water level detection switch 14 sink 2 to be supplied water before detecting water level, thereby reservoir 10 is supplied with (step S1) such as running water.
Afterwards, carry out the heating efficiency estimating step (step S2 ~ step S7) that is consisted of by washings heating steps (step S2 ~ step S4) and washings injecting step (step S5 ~ step S7).In addition, the heating efficiency estimating step is to carry out before the original washing step that tableware 3 jet cleaning water are washed, and is the step of estimating the ability of heater 11 that washings are heated.
In the washings heating steps, washing pump 8 is not moved and energising comes heated scrub water to heater 11, the temperature T 1 through the washings behind the stipulated time t1 (the first stipulated time) is detected.In the washings injecting step, 11 energisings come heated scrub water to heater, and make washing pump 8 move to tableware 3 jet cleaning water, and the temperature T 2 through the washings behind the stipulated time t2 (the second stipulated time) is detected.
Below, the control method of above-mentioned heating efficiency estimating step is specifically described.
At first, 11 energisings of 16 pairs of heaters of control part come heated scrub water (step S2).At this moment, control part 16 is not from Washing spray nozzle 7 jet cleaning water such as Washing spray nozzle such as grade but washings are heated.Therefore, the heat of heater 11 is used for making the temperature of washings to rise, and therefore is used for hardly making the temperature of tableware 3 to rise.
Then, elapsed time t1 is when (the first stipulated time) (step S3 is "Yes") after beginning heater 11 energisings, and thermistor 13 detects the temperature T 1 (step S4) of washings.At this, from water unit 15 to reservoir 10 supply water after the regulation water yield that is detected by water level detection switch 14 and measuring the temperature of washings before setup times t1, this be since when utilizing thermistor 13 indirectly to detect the temperature of washings generation time postpone.Therefore, the variation of the temperature rising of the washings that caused by heater 11 is followed in the variation of the temperature rising of the bottom (installation portion of thermistor 13) of wait sink 2.That is to say, after beginning heater 11 energising not in the situation of elapsed time t1 (the first stipulated time) (step S3 is "No") proceed the washings heating steps, until time t1 (the first stipulated time) process.
Afterwards, under the state that continues heater 11 energisings, begin to make the washings injecting step (step S5) of washing pump 8 actions.And time t2 (the second stipulated time) utilizes thermistor 13 again to detect the temperature T 2 (step S7) of washings through out-of-date (step S6 is "Yes") after beginning heater 11 energisings.At this moment, after beginning heater 11 energising not (step S6 is "No") in the situation of elapsed time t2 (the second stipulated time), carry out standby until time t2 (the second stipulated time) process.
At this, effect, the effect that when detecting the temperature T 2 of washings washing pump 8 is moved described.
At first, in the situation that washing pump 8 is failure to actuate, only by the convection current by the heated scrub water generates make temperature in reservoir 10 from high temperature to the low temperature transmission.This is effective for tableware 3 not being supplied with heat.But, when near the situation that drops into washing agent that disposes thermistor 13 of sink 2 inside, owing to the diffusion effect of washing agent causes convection current to change.Thereby the temperature of the washings that former cause thermistor 13 detects produces error.Therefore, in the present embodiment, make washing pump 8 move agitator treating water, thereby make the temperature of washings even.Accuracy of detection when thus, utilizing thermistor 13 to measure the specific temperature rise of washings is stable.At this moment, make washing pump 8 move and detect under the temperature conditions of washings, washings pour on the tableware 3, so the heat of washings is absorbed by tableware 3.But, till the heat of washings is absorbed by tableware 3, need the time.Therefore, absorbed the impact that is brought for fear of the heat of washings by tableware 3, will set the actuation time of washing pump 8 to such an extent that lack (for example, about 1 minute).
At this moment, in the washings injecting step, the heat that is produced by heater 11 within the time of heated scrub water (t2-t1) is used for the known object of the thermal capacity such as wall by the reservoir 10 of the washings of the water level detection switch 14 detected regulation water yields and sink 2 is heated, and is not subjected to the impact of the capacity of the tableware 3 in the sink 2.
Thereby the temperature T 1 of the washings the when temperature T 2 of the washings during according to time t2 and time t1 is measured the ascending temperature (T2-T1) of washings.Thus, even occured in the situation of change being provided with supply voltage under the environment of dish cleaning machine, also can estimate to be equivalent in sink 2, not take in by the intrinsic heater 11 that every dish cleaning machine possesses the heating efficiency for washings of the state of tableware 3.
In addition, in washings heating steps and washings injecting step, may not be in advance to heater 11 energisings in whole step.That is to say, as long as just can calculate the input heat conduction time of HEATER FOR MEASURING 11 in advance, therefore can estimate the heating efficiency of above-mentioned heater 11.
By like this, the ascending temperature (T2-T1) of measuring can be defined as the specific temperature rise of the washings of time (t2-t1) in the heating efficiency estimating step.
Afterwards, under the state that heater 11 is continued energising, begin washing step (step S8) for wash dining set 3.At this moment, with the washings injecting step washing pump 8 is moved, towards tableware 3 jet cleaning water.
Whether the temperature T of then, judging washings is less than set point of temperature, for example 45 ℃ (step S9).At this moment, the temperature T of washings less than 45 ℃ situation under (step S9 is "Yes"), utilize heater 11 to continue heating, the temperature T of washings is measured (step S10) from 45 ℃ of time dt that rise to 60 ℃.
In addition, in washing step, tableware 3 sprayed on one side carry out the heating of washings on one side, therefore the time with washing pump 8 actions is set as longer than the actuation time in the above-mentioned heating efficiency estimating step.Therefore, different from above-mentioned heating efficiency estimating step, the speed that temperature rises is subject to the impact of the capacity of tableware 3.Therefore, consider that the temperature T of the washings of measuring from the heating efficiency of 45 ℃ of heaters 11 that rise to 60 ℃ time dt and estimate, compares the specific temperature rise of the washings in the heating efficiency estimating step and the specific temperature rise of the washings in the washing step the heating efficiency estimating step in step S10.Thus, can estimate to make the temperature of tableware 3 rise required heat, be the capacity (step S11) of tableware 3.
Utilize Fig. 3 that the method for the capacity of estimation tableware 3 is specifically described.
Fig. 3 with " greatly " of capacity, " in ", " little " show the relation of the capacity of the tableware 3 that the time dt according to the ascending temperature in the heating efficiency estimating step (T2-T1) and washing step estimates.At this, for example take with the capacity relative of the actual tableware of taking in 3 in the ratio of the capacity that sink 2 can be taken in be made as " greatly " greater than 2/3 situation, the situation of aforementioned proportion as 1/3 to 2/3 be made as " in ", mode that aforementioned proportion is made as " little " less than 1/3 situation represents the capacity of tableware 3.
At this moment, the specific temperature rise of the washings in the heating efficiency estimating step is higher, and the heating efficiency of heater 11 is higher.Therefore, as shown in Figure 3, in washing step, even rise to from 45 ℃ in the short situation of time till 60 ℃ (for example, dt shown in Figure 3 (second) 1000 ~ 1100) at washings, the capacity that also is judged to be tableware 3 is large.
Then, with the capacity of the tableware 3 that in step S11, estimates correspondingly, decide the maximum temperature that before the heating rinse step finishes, should arrive namely to heat the drying steps time tk (step S12) that rinsing arrives temperature T k and drying steps based on value shown in Figure 4.Figure 4 illustrates the capacity of the tableware 3 that in step S11, estimates and an example of the relation of heating rinsing arrival temperature T k, drying steps time tk.As shown in Figure 4, for example at the capacity that is judged as tableware 3 when " greatly ", the arrival temperature T k that heats rinsing is set as 70 ℃, the time tk of drying steps is set as 25 minutes.Similarly, for example at the capacity that is judged as tableware 3 be " in " time, the arrival temperature T k of heating rinsing is set as 68 ℃, the time tk of drying steps is set as 20 minutes, for example when the capacity that is judged as tableware 3 is " little ", the arrival temperature T k of heating rinsing is set as 66 ℃, the time tk of drying steps is set as 15 minutes.
At this, in the step S9 of Fig. 2, for example the temperature T of the washings when owing to being connected with hot water supply apparatus washing step being begun is (step S9 is "No") in the situation of set point of temperature more than 45 ℃, be made as the capacity estimation (can not judge) that to carry out tableware 3, will heat rinsing and arrive temperature T k and drying steps time tk and be set as (with reference to Fig. 3) identical controlled condition (step S20) when being judged to be tableware capacity " greatly ".This is in order to be judged as in the situation about can not judge, and though the capacity of tableware 3 be " little ", " in ", " greatly ", all fully to tableware 3 wash, drying.Thus, even in the situation of having used the dish cleaning machine that is connected with hot water supply apparatus, also can be fully to tableware 3 wash, drying.
Then, temporarily discharge washings, utilize the running water of again sink 2 being supplied with via the feed water valve 15 of Fig. 1 to carry out the rinse step (step S13) of tableware 3.Afterwards, 11 energisings of 16 pairs of heaters of control part come heated scrub water, and carry out tableware 3 is heated the heating rinse step (step S14) of rinsing.
At this moment, judge whether through the heating rinsing time (step S15) of regulation.And, in the situation of the heating rinsing time that has passed through regulation (step S15 is "Yes"), judge whether the temperature of washings has surpassed the heating rinsing arrival temperature T k (step S16) that determines.Temperature at washings has surpassed in the situation that heats rinsing arrival temperature T k (step S16 is "Yes"), finishes heating rinse step (step S17).On the other hand, in the situation of the heating rinsing time that does not pass through regulation (step S15 is "No"), proceed to heat rinse step, until the heating rinsing time of regulation process.Similarly, do not arrive in the situation that the heating rinsing arrives temperature T k (step S16 is "No") in the temperature of washings, proceed to heat rinse step yet, arrive temperature T k until the temperature of washings surpasses the heating rinsing.
Then, when the heating rinse step finishes (step S17), beginning drying steps (step S18).Afterwards, judge whether the drying steps time tk that the capacity according to tableware 3 determines passes through (step S19).In the situation of drying steps time tk process (step S19 is "Yes"), finish drying steps, and finish the running of dish cleaning machine.On the other hand, drying steps time tk not (step S19 is "No") in the situation of process, proceed drying steps, until drying steps time tk process.
In addition, show particularly in the above-described embodiment temperature, threshold value for the washings of Measuring Time dt, but be not limited to this.Unit when heating rinsing arrival temperature T k, drying steps time tk to calculating does not limit especially, can set with other scope temperature, the threshold value of washings yet.Thus, can control arbitrarily according to purposes, can realize more efficient dish cleaning machine.
In addition, in the above-described embodiment, the capacity that rises, estimates tableware 3 take the temperature of measuring washings in washing step is illustrated as example, but is not limited to this.For example, the temperature that also can measure washings in the heating rinse step rises, and sets the heating rinsing and arrives temperature T k, drying steps time tk.
In addition, in the above-described embodiment, take according to the corresponding controlled condition of capacity of the tableware 3 that estimates, namely heat rinsing and arrive temperature T k and drying steps time tk and carry out heating rinse step and drying steps and be illustrated as example, but be not limited thereto.For example, also can change according to the capacity with tableware 3 the arrival temperature of heating rinse step and drying steps at least one condition in the time of drying steps.Thus, can carry out according to the capacity of tableware 3 suitable heating rinsing, drying, the time energy-conservation and that shorten heating rinse step, drying steps etc. is not realized on performance ground.
As mentioned above, according to dish cleaning machine of the present invention,, can be more reliably the capacity of tableware etc. be judged because the intrinsic deviation of each equipment that the wattage (caloric value) of the heating parts such as heater 11 produces, the impact of power supply voltage variation generation by suppressing.Thus, can determine that according to the capacity of tableware best heating rinsing arrives temperature, drying steps time, and heat rinse step and drying steps based on this.Consequently can realize energy-saving, the saving wash time of dish cleaning machine.
In addition, the thermistor that only utilizes the temperature detection of existing washings to use just can be realized based on the change of wattage (caloric value) capacity of tableware etc. being judged.Thus, do not need to reset the voltage detection circuit that the change that detects supply voltage comes the heating part such as control heater, therefore can small-sized, the simple dish cleaning machine of implementation structure.
In addition, in the present embodiment, for example take with the capacity relative of the actual tableware of taking in 3 in the ratio of the capacity that sink 2 can be taken in be made as " greatly " greater than 2/3 situation, the situation of aforementioned proportion as 1/3 to 2/3 be made as " in ", aforementioned proportion is represented the capacity of tableware 3 less than the mode that 1/3 situation is made as " little ", but be not limited to this.Also can change by the setting range to the time dt of the ascending temperature in the heating efficiency estimating step (T2-T1) and washing step, change the ratio of the capacity of tableware 3.
