Embodiment 1
[0061] figure 1 is the flow chart of the refrigerator defrosting control method provided by the first embodiment of the present invention, as figure 1 As shown, the method includes the following steps:
[0062] S101 , according to the information affecting the frosting of the evaporator, correct the accumulated working time of the compressor to obtain the corrected working time of the compressor.
[0063] S102, according to the corrected working time of the compressor, the temperature difference between the temperature of the inlet pipe of the evaporator and the temperature of the pipe at the return air outlet of the evaporator, determine whether to enter the defrosting process.
[0064] Among them, the main effect of the frost formation on the evaporator is to affect the frost formation rate. The information that affects the frosting of the evaporator includes: the temperature change information of the compartment caused by the door opening action; or, the information that ...
Embodiment 2
[0126] The above-mentioned defrosting control method for a refrigerator will be described below with reference to a specific embodiment. However, it should be noted that this specific embodiment is only for better description of the present application, and does not constitute an improper limitation of the present application. Terms that are the same as or corresponding to the above-mentioned embodiments are explained, and are not repeated in this embodiment.
[0127] refer to figure 2 , is a schematic diagram of the evaporator assembly, including: evaporator inlet pipe 1, evaporator outlet pipe 2, accumulator 3, evaporator coil 4, fins 5, left bracket 6, right bracket 7, small bracket 8, buckle 9. A first defrost sensor 10, a second defrost sensor 11 and a heater 12 (eg, a steel pipe heater). The first defrost sensor 10 is fixed on the evaporator inlet pipe 1 through the buckle 9, and is used to detect the pipe temperature at the evaporator inlet pipe 1, such as image 3 A...
Embodiment 3
[0154]Based on the same inventive concept, this embodiment provides a refrigerator defrosting control device, which can be used to implement the refrigerator defrosting control method described in the above embodiments. The device can be implemented by software and / or hardware, and the device can generally be integrated in the controller of the refrigerator.
[0155] Figure 5 is the structural block diagram of the refrigerator defrosting control device provided by the third embodiment of the present invention, such as Figure 5 As shown, the device includes:
[0156] The correction module 51 is used to correct the accumulative working time of the compressor according to the information affecting the frosting of the evaporator to obtain the corrected working time of the compressor;
[0157] The determination module 52 is configured to determine whether to enter the defrosting process according to the corrected working time of the compressor, the temperature difference betwee...
