Referring to Fig. 3, in some embodiments, step S51 and step S52 can be realized by confirmation module 24, namely
It is to say, confirmation module 24 can be used for, when liner 10 intakes front and back temperature absolute value of the difference less than preset value, confirming washing electricity
Device 100 is intake exception, is also used for, when liner 10 drains front and back temperature absolute value of the difference and is less than preset value, confirming washing electric appliance
100 drainings are abnormal.
Referring to Fig. 5, in some embodiments, step S51 and step S52 can be realized by processor 32, that is, be handled
Device 32 can be used for, when liner 10 intakes front and back temperature absolute value of the difference less than preset value, it is different confirming that washing electric appliance 300 is intake
Often, it is also used for, when liner 10 drains front and back temperature absolute value of the difference and is less than preset value, it is different confirming that washing electric appliance 300 drains
Often.
Specifically, in fill phase, the temperature of liner 10 is low before intaking, and the temperature of liner 10 is high after normal water inlet.When into
When temperature absolute value of the difference before and after water is less than preset value, shows to wash electric appliance 100 and intake exception.Before bleeding stage, draining
The temperature of liner 10 is high, and the temperature of liner 10 is low after proper drainage.When the front and back temperature absolute value of the difference of draining is less than preset value
When, show that washing electric appliance 100 drains exception.
In addition, when determining the water inlet of liner 10 and/or abnormal draining, washing electric appliance 100 can not start circulating pump 14 and hair
Heat pipe 13 avoids the no-load running of washing electric appliance 100 and prevents heat-generating pipe 13 from running heating in water deficiency and washing electricity is lost
Device 100.
