It should be noted that, in step S710, the first cooling fan 123 is controlled to be stopped when it is determined that the compressor 42 is stopped, and in step S716, the second cooling fan 124 is controlled to be stopped when the compressor 42 is stopped for the second preset time, provided that the compressor 42 is in the operating state before, and both the first cooling fan 123 and the second cooling fan 124 are in the operating state. Under this premise, the first cooling fan 123 and the second cooling fan 124 which are originally in the operating state can be controlled to be stopped after the compressor 42 is stopped.
Further, the first preset time period in step S706 may be set to 1 minute. The second preset time period in step S714 may be set to 2 to 5 minutes. One embodiment is described below: if the first preset time period is 1 minute and the second preset time period is 3 minutes, the first cooling fan 123 is immediately controlled to be turned on when the compressor 42 is determined to be turned on according to the operation signal of the compressor 42, and the second cooling fan 124 is controlled to be turned on when the operation time period of the compressor 42 reaches 1 minute. The first cooling fan 123 is immediately controlled to be stopped when it is determined that the compressor 42 is stopped according to the operation signal of the compressor 42, and the second cooling fan 124 is controlled to be stopped when the stop time period of the compressor 42 reaches 3 minutes.
The heat dissipation control method of the refrigerator of the present embodiment, wherein the refrigerator 100 includes: the compressor comprises a box body 10, a storage space 11 and a compressor bin 12 are defined in the box body 10, the compressor bin 12 is located at the bottom of the box body 10, a first air inlet 121 and a first air outlet 122 are respectively arranged at the left end and the right end of the compressor bin 12, a first cooling fan 123 is arranged at the first air inlet 121, and a second cooling fan 124 is arranged at the first air outlet 122; the air inlet duct 31 is arranged at the bottom of the box body 10 and is communicated with the compressor bin 12 through a first air inlet 121; an air outlet duct 32 disposed at the bottom of the box 10 and communicated with the compressor bin 12 through a first air outlet 122; and a refrigeration system configured to supply cold to the storage space 11, wherein the refrigeration system includes a condenser 41 and a compressor 42 provided in the compressor compartment 12, and the heat dissipation control method includes: acquiring an operation signal and an operation duration of the compressor 42; when the compressor 42 is determined to be started according to the operation signal, the first cooling fan 123 is controlled to be started; judging whether the operation time period of the compressor 42 is greater than or equal to a first preset time period; and if so, controlling the second cooling fan 124 to be started to radiate heat of the compressor bin 12. An air inlet duct 31 and an air outlet duct 32 are respectively arranged at the bottom of the box body 10, so that cold air entering the compressor bin 12 is prevented from being mixed with hot air discharged from the compressor bin 12, and the heat exchange efficiency of the condenser 41 is prevented from being reduced. Make second cooling fan 124 compare first cooling fan 123 and open late, can prevent that the cold wind that gets into compressor bin 12 from being directly discharged for cold wind can be by make full use of, effectively reduces the temperature in compressor bin 12, and heat dissipation control method is more reasonable, strengthens refrigerator 100's radiating effect.
Further, the heat dissipation control method of the refrigerator of the present embodiment controls the first cooling fan 123 to stop when it is determined that the compressor 42 stops according to the operation signal. The step of determining the shutdown of the compressor 42 based on the operation signal further includes: acquiring a shutdown duration of the compressor 42; judging whether the shutdown time length is greater than or equal to a second preset time length or not; and if so, controlling the second cooling fan 124 to stop. After the compressor 42 stops working, the first cooling fan 123 is stopped first to prevent cold air from entering the compressor compartment 12; keeping the second cooling fan 124 running can prevent the hot air in the compressor compartment 12 from remaining and affecting the heat dissipation effect of the refrigerator 100.
Further, in the heat dissipation control method of the refrigerator of the present embodiment, when it is determined that the compressor 42 is turned on according to the operation signal, the first cooling fan 123 is controlled to be turned on; and controls the second cooling fan 124 to be turned on when the operation time period of the compressor 42 reaches the first preset time period of 1 minute. When the compressor 42 is determined to be stopped according to the operation signal, controlling the first cooling fan 123 to be stopped to obtain the stop time of the compressor 42; and controlling the second cooling fan 124 to stop when the stop time reaches the second preset time from 2 minutes to 5 minutes. Above-mentioned specific numerical value of time length and time length is predetermine to first presetting, make opening of first cooling blower 123 and second cooling blower 124, the shutdown time point is more reasonable, effectively strengthen refrigerator 100's whole radiating effect, can effectively reduce refrigerator 100 and around need the radiating distance who reserves between cupboard or the wall, thereby promote refrigerator 100 and the whole pleasing to the eye degree in space around, in addition, can realize freely imbedding cupboard or wall clearance, needn't reform transform cupboard or wall in advance, make the cupboard must be provided with cupboard air intake and cupboard air outlet.
