the second acquisition module is used for controlling the air conditioner outdoor unit to operate based on the preset parameters and acquiring a first temperature of an evaporator in the air conditioner outdoor unit, wherein the first temperature is the temperature of the air conditioner outdoor unit within a first preset time length;
the determining module is used for determining a detection result of the air conditioner outdoor unit based on the current operation state and the preset operation state of the air conditioner outdoor unit under the condition that the first temperature is in a first temperature interval;
the device further comprises: a third obtaining module, configured to obtain a second temperature when the first temperature is not within a first temperature interval, where the second temperature is a temperature of the evaporator within a second preset time period; the updating module is used for updating the preset parameter based on the second temperature under the condition that the second temperature is in a second temperature interval;
the update module includes: a first obtaining unit, configured to obtain a difference between the second temperature and an initial temperature, where the initial temperature is a temperature at which the outdoor unit of the air conditioner starts to perform detection; and the updating unit is used for updating the pulse opening degree of the electronic expansion valve in the preset parameters based on the difference values and preset corresponding relations, wherein the preset corresponding relations are used for representing the pulse opening degrees of the electronic expansion valves corresponding to different difference values.
7. A computer-readable storage medium, comprising a stored program, wherein when the program runs, the program controls an apparatus where the computer-readable storage medium is located to perform the method for detecting the outdoor unit of the air conditioner according to any one of claims 1 to 5.
8. A processor, wherein the processor is configured to execute a program, and the program executes the method for detecting an outdoor unit of an air conditioner according to any one of claims 1 to 5.
