Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows the realization flow of the electric heating device detection method of the air conditioner that the embodiment of the present invention provides, and wherein, air conditioner selects operation to control the break-make of power switch according to the heater switch that user sends; When power switch closes, electric heating device is opened; When power switch disconnects, electric heating device is closed.For convenience of explanation, Fig. 1 illustrate only the part relevant to above-mentioned electric heating device detection method, and details are as follows:
In step sl, air conditioner receive heater switch that user sends select operation time, the working current of electric heating device is detected.
In step s 2, when heater switch is selected to be operating as heating open operation, judge whether the working current of electric heating device is not less than unlatching reference current value, if so, then sends unlatching regular prompt; If not, then send heater element and damage prompting.
Wherein, opening reference current value refers to after user selects opening electric heater part, the current value of work whether is normally opened for weighing electric heating device, it can be the rated working current value of electric heating device and the product of current floating number percent, and the number percent that current floating number percent accounts for rated working current value according to the difference of the real work current value and rated working current value that repeatedly obtain electric heating device is determined.Such as: electric heating device is electric heating tube, its rated working current value after unlatching is I1, and its current floating number percent is in routine duties Δ, then opening reference current value is I1 × Δ.
For step S2, if it is yes for judging whether the working current of electric heating device is not less than the result of opening reference current value, then show that electric heating device is normal unlatching, now sending the step of opening regular prompt can be specially: the pilot lamp controlling air conditioner is lighted using as unlatching regular prompt.
If it is no for judging whether the working current of electric heating device is not less than the result of opening reference current value, then show that electric heating device damages, the step now sending heater element damage prompting can be specially: the pilot lamp controlling air conditioner is pointed out to damage as heater element according to the first predeterminated frequency flashing.
In step s3, when heater switch is selected to be operating as heating shutoff operation, judge whether the working current of electric heating device is not more than closedown reference current value, if so, then sends closedown regular prompt.
Wherein, closing reference current value refers to after user selects to close electric heating device, for weighing the current value whether electric heating device normally closes, it can be determine according to the actual current value of electric heating device when normally closing, such as: electric heating device is electric heating tube, the mean value of its actual current value when repeatedly normally closing is I2, then can using I2 as closedown reference current value.
For step S3, if it is yes for judging whether the working current of electric heating device is not more than closedown reference current value, then show that electric heating device is normal closedown, now sending the step of closing regular prompt can be specially: the pilot lamp controlling air conditioner extinguishes using as closedown regular prompt.
In addition, for step S3, if judge, whether the working current of electric heating device is not more than the result of closing reference current value is no, then show that voltage or the electric current of other circuit in air conditioner seal in electric heating device and cause the working current of now detected electric heating device to be greater than closedown reference current value, so the prompting of circuit Crosstalk Faults now can be sent.The step sending the prompting of circuit Crosstalk Faults can be specially: control the pilot lamp of air conditioner according to the second predeterminated frequency flashing to point out as circuit Crosstalk Faults.Point out to make circuit Crosstalk Faults and be different from above-mentioned heater element damage prompting, need to make the second predeterminated frequency be different from the first above-mentioned predeterminated frequency.
