5. The method as claimed in claim 1, wherein said determining an abnormal condition of a four-way valve of the air conditioner according to the high pressure, the low pressure and the first determination parameter comprises:
and when the ratio of the high-pressure to the low-pressure is smaller than a preset ratio and the air suction temperature of the air conditioner is higher than the indoor environment temperature, judging that the four-way valve is failed to push.
6. The detection control method of the air conditioner as claimed in claim 5, further comprising, after determining that the four-way valve push fails:
and controlling and improving the current valve pushing frequency of the air conditioner so as to enable the four-way valve to push the valve again.
7. The method as claimed in claim 6, wherein said increasing a current valve-pushing frequency of the air conditioner to enable the four-way valve to push again comprises:
and adjusting the current valve pushing frequency by taking the preset valve pushing frequency as an amplification.
8. The method as claimed in claim 6, further comprising, after the step of operating the four-way valve again, the step of:
judging whether the four-way valve fails to push again;
and when the four-way valve pushing failure is judged again, generating a display instruction for indicating the four-way valve pushing failure.
9. A detection control system of an air conditioner, comprising:
the acquiring unit is used for acquiring the high pressure and the low pressure of the air conditioner and acquiring a first judgment parameter;
the judging unit is used for judging the abnormal condition of the four-way valve of the air conditioner according to the high-pressure, the low-pressure and the first judging parameter;
the first judgment parameter comprises the comparison condition of the air pipe temperature of the indoor unit and the defrosting temperature and/or the comparison condition of the indoor environment temperature and the air suction temperature of the air conditioner.
10. An air conditioner comprising a computer-readable storage medium storing a computer program and a processor, wherein the computer program is read by the processor and executed to implement the detection control method of the air conditioner according to any one of claims 1 to 8.
11. A computer-readable storage medium, characterized in that the computer-readable storage medium stores a computer program which, when read and executed by a processor, implements the detection control method of an air conditioner according to any one of claims 1 to 8.
