In addition, by sending abnormality alarming, what the user is recognized occur in the washing machine is unusual, in time allows the maintenance personal overhaul, and the fault of other parts (for example condensate tank of dehumidifier) also can early detection.
(embodiment 2)
Fig. 4 is the power-on servicing sequential chart of the heater of the tumbling-box washing machine among the present invention the 2nd embodiment.As shown in Figure 4, control device to the 1st stipulated time that the major general switches on heater is set for along with the increase of number of times and shortens.Other constitute with the foregoing description 1 in identical.
Below the operational circumstances in the above-mentioned formation is described.In addition, because identical in basic operation and the foregoing description 1 in the washing stroke, so just do not state tiring out at this.
As shown in Figure 4, heater 14 carries out the batch (-type) energising in energising during the 1st stipulated time (80 seconds), outage during the 2nd stipulated time (90 seconds), the number of times that such intermittently power-on is stipulated; Simultaneously, carry out temperature detection, thereby outer bucket 26 interior washings are controlled, are heated on certain basically temperature by temperature-detecting device 18.That is, as shown in Figure 4, the intermittently power-on that carry out for the first time energising in the 1st stipulated time (80 seconds), in the 2nd stipulated time (90 seconds), cuts off the power supply again, carry out for the second time switching in half the 1st stipulated time (40 seconds) of the 1st stipulated time in equaling for the first time, again in the 2nd stipulated time (90 seconds) outage, energising situation for the third time with the second time in the same; Then, carry out continuous energising.
Here, suppose to have in the control device 47 fault to take place,, still switching in the heater 14 although be in anhydrous state in the outer bucket 26.During the energising of the 1st stipulated time (80 seconds), the temperature in the outer bucket 26 will sharply rise.But, because outage in the 2nd stipulated time (90 seconds) can be suppressed so the temperature of outer bucket 26 rises.The number of times that such operation will be stipulated (3 times).Like this, in in during the energising of the 1st stipulated time (80 seconds), temperature-detecting device 18 detected specific temperature rises may reach per 10 seconds 5K as shown in Fig. 3 B, because above-mentioned value has surpassed threshold value 4K, control device 47 is that decision state is unusual, thereby the energising of heater 14 is cut off, prevented the generation of superheat state and fire.
And, because the number of times (3 times) that the operation of such intermittently power-on is only stipulated, heater is just switched on continuously afterwards, and therefore, the required time of the washings in the bucket 26 is compared with the occasion that begins just to switch on continuously at first and do not have very big difference outside the heating in this case.
As mentioned above, owing to make heater carry out intermittently operated in the present embodiment 2, therefore anhydrous in the bucket 26 outside, heater 14 is but still under the occasion of energising, and temperature anomalies risings of comparing with continuous energising in can outer bucket 26 be suppressed at Min., thereby can prevent to damage washing machine.
In addition, needn't change temperature and cross and rise an anti-locking apparatus washing machine is reused, so the security that under the situation of the numerous and diverse degree that does not increase manufacturing cost and maintenance, just can improve washing machine.
In addition, because heater is just switched on after the intermittently operated of having carried out stipulated number (3 times) continuously, therefore the washings in the just outer bucket 26 heat the desired time to be compared with regard to the situation of switching on continuously at first with heater and not have very big difference, thus can be under the situation that not influence the washing time of wanting the security of assurance washing machine.
(embodiment 3)
Fig. 5 is the power-on servicing sequential chart of the heater of the tumbling-box washing machine among the present invention the 3rd embodiment.As shown in Figure 5, control device to the 1st stipulated time of major general's heater energising is arranged to shorten gradually along with the increase of number of times.Other constitute with top embodiment 1 in identical.
Below the operational circumstances in the above-mentioned formation is described.Wherein, because the basic operation in the washing stroke is identical with the above embodiments 1, so omitted being repeated in this description to it at this.
As shown in Figure 5, the intermittently power-on that the 1st time is carried out energising in the 1st stipulated time (80 seconds), cuts off the power supply in the 2nd stipulated time (90 seconds) in the heater 14, carry out in the 1st stipulated time (60 seconds) of 80 seconds weak points energising for the 2nd time than the 1st time, the intermittently power-on of outage during the 2nd stipulated time (90 seconds), the intermittently power-on that carries out in the 1st stipulated time (40 seconds) of 60 seconds weak point, switching on, in the 2nd stipulated time (90 seconds), cutting off the power supply for the 3rd time than the 2nd time; After this, switch on continuously.Simultaneously, temperature-detecting device 18 carries out temperature detection, and the washings in the outer bucket 26 are controlled/are heated on certain basically temperature.
Here, suppose to have in the control device 47 fault to take place, though anhydrous in the outer bucket 26, still switching in the heater 14.Under such occasion, during the energising of the 1st stipulated time (80 seconds) in the 1st when energising in, the temperature in the outer bucket 26 will sharply rise.But owing to cut off the power supply in the 2nd stipulated time (90 seconds), the temperature of outer bucket 26 rises and will be suppressed.When the 2nd energising, because rising has taken place in the temperature of heater to a certain extent, so wherein the 1st stipulated time of switching on is set than the 1st stipulated time short (60 seconds) in the 1st time, and the temperature of heater can excessively not risen.In the 3rd energising, set conduction time to such an extent that also lack (40 seconds) than the 1st stipulated time in the 2nd time, thereby make heater the situation of excessive temperature rising can not occur.
As mentioned above, in present embodiment 3, owing to be after having considered the temperature rising situation of heater to setting the conduction time of heater, therefore, even bucket is anhydrous and under the occasion that heater 14 is still switched in 26 outside, the undue temperature that causes that rises of temperature that also can prevent heater is crossed the phenomenons such as broken string that rise anti-locking apparatus, and the temperature anomaly in the outer bucket 26 is risen is controlled in the Min. simultaneously.Like this, the damage to washing machine just can be prevented.
