Below based on Fig. 3, illustrate running heated scrub stroke and by the climbing of the detected temperature of temperature testing organization under the situation below the setting, reduce work, effect under the situation of control of heating-up temperature.
The running (step 100) of beginning heated scrub stroke, and if water supply operation (step 101) finishes, then washing heater 45 (heating arrangements) begins to carry out heating (step 102) till the design temperature (for example 90 ℃) to washings in washing procedure.If reach specified standard temperature (for example 50 ℃) (S103) by the temperature testing organization water temperature, then measure temperature (for example 60 ℃) required time (specific temperature rise) (step 104) before that begins to reach regulation from this temperature, if surpass first stipulated time (for example 5 minutes), then be judged as quantity more (for example 30L), the washing water temperature is set at first heating-up temperature lower than predetermined heating temperature (for example 70 ℃) (step 105), and washing procedure remains in operation.
In step 106, required time is under the situation below first stipulated time (for example 5 minutes), if surpass next second stipulated time (for example 4 minutes), then be judged as the water yield many a little (20L), heating-up temperature also is set at lower a little and be higher than second heating-up temperature (for example 80 ℃) (step 107) of first heating-up temperature than predetermined heating temperature, washing procedure remains in operation.
Required time is judged as the water yield less (for example 10L) under the situation below second stipulated time (for example 4 minutes), will wash water temperature and be set at predetermined heating temperature (for example 90 ℃) (step 108), and washing procedure remains in operation.
Then,, supply water, will wash water temperature and be cooled to set point of temperature (for example 65 ℃) afterwards, finish washing procedure (step 110) and enter next operation (draining) with water supply mechanism in refrigerating work procedure (step 109).
At this, (L), ⊿ T is as ascending temperature (deg) as the water yield as loss coefficient (1.25), V as proportion (1kg/L), α as thermal capacity (4.18kJ/kgdeg), d as heater power (W), C with W, the water temperature Shang that is used for the water of water yield V (L) Sheng the time h of ⊿ T (minute), through type 1 calculates.That is, as can be known the rise time h of water temperature (minute), be directly proportional with water yield V (L).
[formula 1]
h＝(0.2778×60×C×d×V×⊿T×α)/W
Thereby, therefore by the rise time of washing water temperature, judge the setting of heating-up temperature, to comprise that also the actual amount of water according to the moisture difference of the raw material of washings or kind detects, thereby the mechanical deflection key element is also less, can judge soundly.That is, the situation of the current value with the rotation of the inertia of existing weight sensor or swing roller time the etc. is compared and can more correctly be judged.In addition, according to the washing capacity of determining by above-mentioned result of determination, change the revolution of cylinder or the laundry order of rotation and dwell time setting etc., thereby efficient is higher.
