Embodiment 1
[0043] figure 1 It is a schematic flow chart of a control method for an inverter compressor provided in Embodiment 1 of the present invention. The control method provided in this embodiment is applicable to inverter refrigerators of all capacities (two-door, three-door, or side-by-side doors, etc., different types of volumes), especially for In the scene where the frequency conversion refrigerator works at relatively low voltage, the method can be executed by the control device of the frequency conversion compressor. see figure 1 As shown, the control method specifically includes the following:
[0044] Step 110, after the inverter compressor is powered on, detect the frequency of the square wave signal input to the main control unit.
[0045] For details, see figure 2 The schematic diagram of the peripheral circuit structure of the variable frequency compressor is shown. After the variable frequency compressor is powered on, the input power supplies power to the three-pha...
Embodiment 2
[0056] image 3 It is a flow chart diagram of an inverter compressor control method provided in Embodiment 2 of the present invention. On the basis of the technical solution of Embodiment 1, this embodiment has been further optimized. For details, see image 3 As shown, the method includes:
[0057] Step 310, after the inverter compressor is powered on, detect the frequency of the square wave signal input to the main control unit.
[0058] Step 320, when the frequency of the square wave signal is valid, determine whether the running time of the compressor is longer than the starting time.
[0059] Step 330, if the running time of the compressor is longer than the starting time, set the running speed of the compressor according to the frequency of the square wave signal.
[0060] Specifically, if the running time of the compressor is longer than the starting time and the frequency of the square wave signal is valid, it is considered that the variable frequency compressor is s...
Embodiment 3
[0071] Image 6 It is a schematic structural diagram of an inverter compressor control device provided in Embodiment 3 of the present invention, see Image 6 As shown, the device includes: a detection module 510, a running time judgment module 520, a starting speed setting module 530 and a starting module 540;
[0072] Wherein, the detection module 510 is used to detect the frequency of the square wave signal input to the main control unit after the inverter compressor is powered on;
[0073] The running time judging module 520 is used to determine whether the running time of the compressor is greater than the starting time when the frequency of the square wave signal is valid;
[0074] The starting speed setting module 530 is used to set the starting speed of the compressor according to the frequency of the square wave signal if the running time of the compressor is not greater than the starting time;
[0075] The starting module 540 is used to control the starting of the v...
