Temperature change in 112, and then judge whether dish-washing machine 10 intakes exception, and testing result is accurate, and cost is relatively low.
It is appreciated that typically no installation is for detecting whether the abnormal sensor of water inlet in old-fashioned dish-washing machine, therefore,
Often there is user and forget to open the water inlet pipe leakage of tap or dish-washing machine or other water may being caused to cannot be introduced into wash the dishes
Situation in the cup of machine, so as to cause the motor of dish-washing machine to dally, then cause motor damage.Even if some are new now
Dish-washing machine has the abnormal function of detection water inlet, and for detection method also nothing more than two kinds, a kind of is by the water inlet in dish-washing machine
The flowmeter of installation detects the flow of water, so as to judge whether dish-washing machine intakes exception；Another kind is the nothing by dish-washing machine
Brush direct current (Brushless Direct Current, BLDC) motor judges whether dish-washing machine intakes exception, it will be understood that
BLDC motors in bringing onto load and not bringing onto load electric current it is of different sizes, in other words, when dish-washing machine is whether there is into water BLDC electricity
The size of current of machine is different, so as to judge whether dish-washing machine intakes exception.However, in first method, flowmeter is only
It can guarantee that the water of the water inlet of dish-washing machine is without exception, the water route system for such as passing through flowmeter rear end because other reasonses can not be ensured
System is abnormal, causes water to cannot be introduced into cup, and extra increase flowmeter can add the cost of dish-washing machine.In second method
In, if the motor that dish-washing machine uses is not BLDC motors, but other motors, then it can not judge whether dish-washing machine intakes exception,
Therefore this method has certain limitation, and dish-washing machine judges whether dish-washing machine intakes abnormal need using BLDC motors
Complicated control method is wanted, adds cost.
The dish-washing machine water inlet detection method and dish-washing machine 10 of embodiment of the present invention can be carried using every dish-washing machine 10
Temperature sensor 15 judge whether dish-washing machine 10 intakes exception, specifically, cup 112 is arranged on by temperature sensor 15

Cup 112, is then ejected water in washing cavities 122 by motor, and to wash tableware, water is fallen after rise to water out of washing cavities 122 again
In cup 112, water circulation is realized.In this way, dish-washing machine 10 is at work, the temperature sensor 15 being arranged in cup 112 can be most
First detect whether dish-washing machine 10 intakes exception.
Referring to Fig. 1, in some embodiments, dish-washing machine water inlet detection method also includes：
Second judgment step S70：The absolute value of difference between Current Temperatures and initial temperature is less than predetermined temperature value
When, judge whether be more than or equal to pre-determined number from drain step S10 to the first judgment step S50 execution number；
Second determines step S80：When detecting number and being more than or equal to pre-determined number, determine that dish-washing machine 10 is intake exception；
And
When detection number is less than pre-determined number, drain step S10 is returned.
In some embodiments, the method that processor 16 can be used in S70 and S80.
In other words, processor 16 can be also used for：The absolute value of difference between Current Temperatures and initial temperature is small
When predetermined temperature value, judge make a reservation for whether the first judgment step S50 execution number is more than or equal to from drain step S10
Number；When detecting number and being more than or equal to pre-determined number, determine that dish-washing machine 10 is intake exception；And it is less than in detection number predetermined
During number, control draining valve 14 opens the first scheduled duration.
It is appreciated that when the absolute value of the difference between Current Temperatures and initial temperature is less than predetermined temperature value, show
Current Temperatures are substantially unchanged or range of temperature is smaller relative to initial temperature, can be neglected, thereby it is assumed that
Dish-washing machine 10 is intake exception, but in order that testing result is more accurate, dish-washing machine intake detection method Current Temperatures with just
When the absolute value of difference between beginning temperature is less than predetermined temperature value, also need to judge from drain step S10 to the first judgment step
Whether S50 execution number is more than or equal to pre-determined number, in other words, when 10 continuous pre-determined number of dish-washing machine or more than predetermined
When number detects that the absolute value of the difference between Current Temperatures and initial temperature is less than predetermined temperature value, then it can determine to wash the dishes
Machine 10 is intake exception.
In some embodiments, the first scheduled duration is 30 seconds.
