Detection and/or determining thermal gradient parameter I
According to one embodiment, thermal gradient parameter I can be during initial heating step in reference time interval (example
Such as, constant and scheduled) in the increase (that is, poor) of temperature that is detected by temperature sensor 9 and be therefore temperature difference.The temperature
Degree difference is bigger, and the heating speed of cleaning solution and tableware 3 is bigger, therefore this gets over the quantity for indicating tableware 3 to be washed or quality
It is small.The temperature difference is smaller, and the heating speed of cleaning solution and tableware 3 is smaller, therefore this will indicate the quantity of tableware 3 to be washed
Or quality is bigger.
According to other embodiment, thermal gradient parameter I can be during initial heating step at reference time interval

More precisely, in an illustrative manner, measured cleaning solution temperature difference (T_ targets _ minimum-T2) can be predetermined
Or predeterminable nominal cleaning solution heating temperature T_ targets _ minimum (such as 55 DEG C) of minimum (therefore activating with not heating also
Heating device 10 is previously measured) cleaning solution initial temperature T2 between difference.In this case, duration t1 is to add
Elapsed time between minimum nominal temperature T_ targets _ minimum (T_target_min) is connected and reached to thermal 10.Continue
Time t1 is not constant (because it depends on the quality of tableware and whole thermal capacity), and by comparing by control device 12
The temperature detected by temperature sensor 9 verifies reaching for minimum nominal temperature T_ targets _ minimum with reference value T_ targets _ minimum
It arrives.
Adjust parameter-temperature of hot washing step
According to one embodiment, electronic control unit 12 is adjusted according to thermal gradient parameter I in the heating washing step phase
Between heating device 10 connect duration or heating device 10 heating power.Particularly, when thermal gradient (parameter) I relative to
When the reference value of preset time and/or power and/or thermal gradient reduces, control device 12 increases connecing for heating device 10
The duration in logical stage and/or the heating power of heating device 10.Therefore, with the quality or quantity of pending tableware 3
Increase, the duration in the connection stage of heating device 10 and/or heating power increase.
According to one embodiment, control device 12 adjusts the maximum nominal temperature of cleaning solution according to thermal gradient (parameter) I
T_ targets _ maximum value, and executed by heating device 10 and temperature sensor 9 and verification maximum nominal temperature T_ targets _ most
Big value reaches.
Particularly, the value of maximum nominal temperature T_ targets _ maximum (T_target_max) of cleaning solution is with thermal gradient (ginseng
Number) I reduce and increase, this instruction thermal inertia it is larger and be therefore loaded in wash container 2 in tableware 3 quality and quantity more
Greatly.
As a result, as the quality and/or quantity of pending tableware 3 increase, maximum temperature that cleaning solution is heated and
Therefore it is transmitted to tableware and the total amount of heat of cleaning solution increases automatically.
Similarly, with the quality and/or quantity of pending tableware 3 reduce, the maximum temperature that cleaning solution is heated with
And it is therefore transmitted to tableware and the total amount of heat of cleaning solution and reduces automatically.
According to one embodiment, regardless of the useful load of the tableware 3 detected by above-mentioned temperature gradient, electronic control
The adjustment maximum nominal temperature T_ targets _ maximum in fixed temperature interval (for example, 55 DEG C to 65 DEG C) of device 12, wherein fixed
Lower value (for example, be more than 45 °) ensure the temperature of enough heat for activating chemically and physically dirt removal mechanism, and consolidate
Fixed higher value (for example, being less than 75 °) prevents the cause thermal damage to tableware 3 and dish-washing machine 1.
Adjust parameter-duration of hot washing step
According to one embodiment, during hot washing step, electronic control unit 12 keeps heating device 10 to connect directly
It reaches maximum nominal temperature T_ targets _ maximum of cleaning solution and is reaching maximum nominal temperature T_ targets _ maximum (by temperature
Sensor 9 detect) when cut off heating device 10, but be to continue with actuating injection apparatus 4 with by means of pre-heated cleaning solution
To wash tableware 3 and cut off heating device 10 duration T 2 is washed to carry out delayed heat.
By the adjustment according to the above-mentioned maximum nominal temperature (T_ targets _ maximum) of thermal gradient (parameter) I, with detecting
Thermal gradient reduce (indicate pending tableware 3 quality and/or quantity it is bigger), the duration of initial heating step and
It the maximum temperature that reaches and is therefore transmitted to tableware and the total amount of heat of cleaning solution and can increase automatically.
Similarly, as the thermal gradient detected increases and (indicates that the quality of pending tableware 3 and/or quantity are smaller),
The duration of initial heating step and the maximum temperature reached and the total amount of heat meeting for being therefore transmitted to tableware and cleaning solution
It is automatic to reduce.
It is further favourable that control device 12 is according to thermal gradient (parameter) I determinations or the residue of calculating hot washing stage
The value of duration t2.Particularly, as thermal gradient (parameter) I reduces, that is, with thermal inertia and be therefore loaded in washing and hold
The quality and quantity of tableware 3 in device 2 increases, and the value of the remaining duration t2 in hot wash stage increases.
Therefore, as the quality and/or quantity of pending tableware 3 increase, the hot washing stage of heating device 10 is cut off
Remaining duration t2 increase automatically, therefore transfer heat to tableware and cleaning solution using the long period and wash tableware
3 time is longer.
Similarly, as thermal gradient (parameter) I increases (quality and/or quantity smaller that indicate pending tableware 3), tool
There is the duration of the hot washing step of heating cut-out to reduce automatically, to save time and electric power.
According to one embodiment, regardless of the useful load of the tableware 3 detected by above-mentioned temperature gradient, control device
12 in Fixed Time Interval (for example, 300 seconds to 1200 seconds) internal cutting off heating device 10 by adjusting the surplus of hot washing stage
Remaining duration t2, wherein fixed lower value (for example, being more than 240 seconds) ensures using the washing having been introduced into system
Liquid and heat, and fixed higher value (for example, being less than 1300 seconds) is prevented to being cleaned with existing dirt cleaning solution
Tableware carry out it is unnecessary and repeat processing.
Parameter-duration of the follow-up cold rinse step of adjustment
According to one embodiment, at the end of hot washing step, electronic control unit 12 activate cleaning solution discharge and
Such as the loading of the cold rinsing liquid (especially cold running water) by one or more inlet valves 13, in cut-out heating device 10
And when executing cold rinse step in the case of connecting injection apparatus 4 to rinse the lasting cold rinsing of the tableware previously washed 3 persistently
Between t3.
According to one embodiment, electronic control unit 12 adjusts the cold rinsing duration according to thermal gradient (parameter) I
t3。
Particularly, the duration t3 of cold rinse stage increases as thermal gradient (parameter) I reduces, this instruction thermal inertia
It is larger and be therefore loaded in washing container 2 in tableware 3 quality and quantity bigger.
Therefore, with the quality and/or quantity of pending tableware 3 increase, the duration t3 of cold rinse stage and
Therefore residence time of the rinsing liquid on tableware increases automatically, to provide the more time for a greater amount of tableware of rinsing and go back
The remaining thermal energy being stored in tableware is utilized in a manner of more complete.
Similarly, as the quality and/or quantity of pending tableware 3 reduce, cold rinsing duration t3 and therefore
Residence time of the cold rinsing liquid on tableware reduces automatically, to save electric power and time.
According to one embodiment, regardless of the useful load of the tableware 3 detected by above-mentioned temperature gradient, electronic control
Device 12 adjusts the duration t3 of cold rinse step in Fixed Time Interval (for example, 120 seconds to 240 seconds), wherein fixed
Lower value (for example, be more than 100 seconds) ensure minimum rinsing, and fixed higher value (for example, being less than 300 seconds) prevents from rinsing
The unnecessary extension of step and correlation energy consumption.
