The fault cues method that embodiment provides is applicable to be provided with the refrigerator (refrigerator to circulate currently on the market of LED illumination lamp
LED illumination lamp is equipped in refrigerating chamber), refrigerator, showcase or fresh cabinet etc..This method can be by being based on LED illumination lamp
Fault cues device perform, software may be employed in described device and/or the mode of hardware is realized.It is shown in Figure 1, it is described
Fault cues method specifically includes as follows：
Step 110, in refrigerator operational process, detection refrigerator parts whether break down.
Illustratively, the refrigerator parts can include fan electromotor, freezing sensor, defrosting sensor or circumstance temperature
At least one of sensor can also be related to other a variety of parts in refrigerator operational process, therefore can also include
Other parts.Wherein, its essence is a kind of temperature-sensitive electricity for the freezing sensor, defrosting sensor or circumstance temperature sensor etc.
Resistance, when ice the temperature inside the box changes, the resistance value of the sensor changes, and the variation of resistance value further causes voltage
Variation, the voltage of variation cause control circuit to enter different operating modes, control start-stop or the defrost of compressor respectively.When
When these sensors break down, such as short circuit or open circuit, detection signal can be sent by refrigerator master control borad, detects its both ends
Voltage to judge which kind of failure specifically has occurred.Specifically, for example by detecting the voltage at freezing sensor both ends, electricity
Pressure value is more than given threshold, it is determined that short trouble has occurred in the freezing sensor, can control LED illumination lamp according to certain
Frequency is into line flicker, to carry out fault cues.When carrying out system design, a fault cues corresponding table can be preset,
LED illumination lamp is used to indicate according to which kind of frequency into line flicker, represents which kind of failure refrigerator occurs.For example, work as LED illumination lamp
According to the frequency of 5 times/second into line flicker, represent that short trouble occurs in freezing sensor；When LED illumination lamp is according to 10 times/second
Frequency into line flicker, represent that short trouble occurs in freezing sensor.When LED illumination lamp is dodged according to the frequency of 1 time/second
It is bright, represent that failure etc. occurs in fan electromotor.It, can be straight after being determined that specifically which type of failure occurs in which parts
Connecting the mode tabled look-up controls LED illumination lamp according to predeterminated frequency into line flicker.It for details, reference can be made to shown in Fig. 2 based on LED
The fault cues logic relation picture of headlamp sends detection signal, according to parts by refrigerator master board to parts
Feedback signal judges that kind of failure occur in parts, further sends corresponding control signal, control to LED illumination lamp
LED illumination lamp processed is according to certain frequency into line flicker.
Further, when the refrigerator parts are specially fan electromotor, whether the fan electromotor for detecting refrigerator occurs
Failure can be realized by following detection method：

To export amplified second voltage signal；Control unit 106 is connected to the amplifying unit 104, for receiving the amplification
The second voltage signal that unit 104 exports, and judge that the refrigerator fan motor is according to the variation of the second voltage signal
No generation stall.In Fig. 3, R5 is current sense resistor, and Ifan is fan input current, when fan motor rotational speed is abnormal or stifled
When turning, Ifan can increase.During fan electromotor normal operation, fan electromotor terminal voltage accounts for 11V, and R5 terminal voltages are 1.02V or so,
When fan electromotor stall, because immediate current increases, therefore R5 both ends can generate the instantaneous voltage of about 2.85V or so, subsequent R5 two
The voltage at end weakens, and about 0.08V, according to more than characteristic, combined circuit feature can be as the spy for judging motor abnormality or stall
Sign.During practical application, because voltage is faint, by using amplifying unit 104, the amplified electricity in R5 both ends is detected by control circuit
Pressure value, according to change procedure as described above, judge fan electromotor whether stall.
If step 120, refrigerator parts break down, LED illumination lamp is controlled to be dodged according to different flash patterns
It is bright.
