Like this, according to washings amount and inflow temperature difference, under the big occasion of wash time loads long, motor such as many or inflow temperature is low at washings, the mechanical agitation power that can suppress first half, the driving that reduction causes because of the temperature of motor rises is bad, and can guarantee to rise to the wash time before the set point of temperature.
On the other hand, at washings few or inflow temperature height etc. the time, because that the temperature of washings rises is very fast, wash time can shorten, and the clothing damage that produces because of high-temperature wash, shrinking also can alleviate.
The 3rd scheme of the present invention is, the upper limit time that detects setting in the 1st agitation stroke of the high-temperature wash stroke in the 1st or the 2nd scheme is that the 1st stipulated time and the upper limit time that detects setting in the 2nd agitation stroke are under the occasion of the 2nd stipulated time, present ongoing stroke is finished, enter next stroke.Like this, in because of described heater or described temperature-detecting device, break down etc. and to detect under the occasion less than described set point of temperature, not simply present stroke to be gone on, but present ongoing stroke is finished, then enter next stroke in the predefined the 1st or the 2nd stipulated time.Like this, can the burden that be added on the described motor be limited, suppress the driving bad phenomenon that Yin Wendu rises and causes.
The 4th scheme of the present invention is, the high-temperature wash stroke described in the 1st~3 invention stir required MIN the 3rd stipulated time during.Like this, at washings few or inflow temperature height etc. the time, because shortened the heat time heating time of washings, described agitation stroke can finish earlier, the phenomenon that the effect of scourability, degerming performance reduces can prevent, thereby be expected to guarantee scourability and the degerming performance of high-temperature water in cleaning, and make it to reach optimization.

Below, come operational circumstances and effect in the formation of tumbling-box washing machine with above-mentioned formation are described by the flow chart among Fig. 4, trip map among Fig. 5.
During laundry, the user at first opens cover 31, drops into washings in swing roller 24, begins operation in step 100.After the operation beginning, connect power switch 45f in step 101 earlier, set high temperature mode (as the degerming pattern) in step 102 by operator scheme configuration switch 45d then.In step 103, have or not change to judge to the setting of water level, water temperature, wash time, rinsing number of times, dewatering time.If change is arranged, then first operated wash time setting switch 45a, rinsing number of times configuration switch 45b, dewatering time configuration switch 45c, water level change input setting switch 45h and water temperature change input switch 45i change various settings, demonstrate changed content by display unit 46 again in step 104.Under the occasion that does not have change, then transfer to step 105.In step 105, operation is located at the starting switch 45e on the control device 43, the beginning laundry operations.After laundry operations begins, at first making hood lock 40 lockings in step 106 by control device 44, is that step 107 makes water intaking valve 37 work at next procedure, adds water; And judge by condensate tank of dehumidifier 39 whether the water that adds has reached the water level of regulation in step 108.If reached the water level of regulation, then enter the washing stroke in the step 109, motor 28 begins to drive swing roller 24 rotations, carries out stirring operation, carries out the 1st agitation stroke in the washing stroke.If also do not reach the water level of regulation, then be back to step 107.In washing stroke, swing roller 24 is rotated with rotational speed N under the driving of motor 28, makes the washings in the swing roller 24 be mentioned, drop on the water surface again by lobe plate 29, carries out the washing of " knocking " formula.
In step 110,41 pairs of washings of control device 44 control heaters heat.In step 111, judge by temperature-detecting device 42 whether the temperature T of washings has been heated to more than the 2nd set point of temperature T2 (as 50 ℃), if more than the 2nd set point of temperature T2, then transfer to the 2nd agitation stroke in the step 112; If also do not reach the 2nd set point of temperature T2, then be back to step 110.As mentioned above, the high-temperature wash stroke is divided into the 1st agitation stroke (first half) in the step 109 and two parts of the 2nd agitation stroke (latter half) of step 112 here.
In addition, as shown in the following formula 1, the 1st agitation stroke of above-mentioned first half in the time time ratio X1% of shut-down operation and stirring operation be configured to be lower than stopping in the 2nd agitation stroke of described latter half and compare X2% with mixing time.
[formula 1]
(1) in the 1st agitation stroke, carry out repeatedly under the occasion of " stir and stopped 23 seconds in 7 seconds ",
The time scale X1% that stirs in the 1st agitation stroke
=7 seconds ÷ (7 seconds+23 seconds) * 100=23%
(2) in the 2nd agitation stroke, carry out repeatedly under the occasion of " stir and stopped 8 seconds in 15 seconds ",
The time scale X2% that stirs in the 2nd agitation stroke
=15 seconds ÷ (15 seconds+8 seconds) * 100=65%
So X1%<X2%
In addition, when washings more (as 6kg) or inflow temperature lower (as 15 ℃), compared with washings more after a little while when (as 1kg) or inflow temperature higher (as 30 ℃), it is longer that the temperature of washings rises to the required time of the 2nd set point of temperature T2, so the time of the 1st agitation stroke of first half, the time of stirring simultaneously was that actual driving time, the clothing of motor will be tailed off by the actual time of stirring with elongated.
At next procedure is in the step 113, and the temperature T by 42 pairs of washings of temperature-detecting device is judged more than whether being heated to the 1st set point of temperature T1 (for example 90 ℃).If reached more than the 1st set point of temperature T1, then enter step 114, make heater 41 shut-down operations by control device 44.If also do not reach the 1st set point of temperature T1, then be considered as high-temperature wash and also do not finish, turn back in the step 112.
After washing stroke was finished, control device 44 made motor 28 stop to drive in step 115, makes swing roller 24 stop to stir rotation, and carried out follow-up stroke such as rinsing in step 116.
As mentioned above, in the high-temperature wash stroke that carries out in the present embodiment, by reducing the stirring operation in reaching the 2nd set point of temperature T2 (as 50 ℃) first half (the 1st agitation stroke) before, can alleviate the burden that drives swing roller 24 motor rotating 28, the driving that prevents that Yin Wendu from rising and occur is bad, though also can be before all operations stroke finishes under the occasion that wash time is extended operate as normal.In addition, by prolonging the dwell time between the stirring operation, can give play to the effect of emerge in worm water washing, cleaning performance also can be improved.
In addition, in the 2nd agitation stroke of latter half, to the condition of high temperature of the 1st set point of temperature T1 (as 90 ℃), carry out stirring operation by being in the 2nd set point of temperature T2 (as 50 ℃) in the washing water temperature, high-temperature wash liquid is arrived between the washings fully, and cleaning performance and degerming performance can be improved.
Like this, in washings more (as 6kg) or inflow temperature lower (as 15 ℃), because washings rise to the 2nd set point of temperature T2 and need the regular hour, the time of the 1st agitation stroke of first half can be elongated, but can alleviate the burden that is added on the motor 28 by suppressing actual mixing time, and can guarantee to arrive the washing stroke time that required high temperature is the 1st set point of temperature T1.In contrast, at washings less or inflow temperature higher in, because it is shorter that the temperature of washings rises to the required time of set point of temperature, the washing stroke time can shorten, the stirring number of times of clothing can reduce, so phenomenon such as the cloth surface damage of the washings that causes because of high-temperature stirring, shrink can alleviate.
(embodiment 2)
Fig. 6 is the outline operation flow chart of the tumbling-box washing machine in the present invention's the 2nd embodiment.
In the present embodiment, in described the 1st agitation stroke when carrying out described high-temperature wash stroke, the low stirring that control device 44 is lower with mixing time (for example stir and stopped 23 seconds in 7 seconds) and low stir mixing time to stir (for example stir and stopped 4 seconds in 20 seconds) to be made up than higher height compared with this, constitute an agitation cycle, and constantly repeat such circulation.Like this, the low not high problem of wash agitation deficiency, water temperature accuracy of detection that causes of actual stirring ratio because of swing roller can be resolved in the 1st agitation stroke of first half.Other constitute because of with above-mentioned embodiment 1 in identical, so put on identical symbol at this, omission is to being repeated in this description that it carries out.
