Referring to fig. 2, the control method of the refrigerator of the present invention performed by the control apparatus 200 of any of the above-described embodiments may include at least the following steps S202 to S206.
Step S202: acquiring the running state of a fan 110 of the refrigerator 100, and identifying whether the fan 110 is in a fault state according to the running state;
step S204: if yes, determining the fault type of the fan 110, and acquiring a fault elimination strategy which is configured in the refrigerator 100 in advance and corresponds to the fault type;
step S206: the refrigerator 100 is controlled to operate according to a corresponding trouble shooting strategy.
Wherein, the above-mentioned judging whether the fan is in the fault state includes but not limited to through following mode: the preset power P0 is input through the PWM control input end, and if a certain rotation speed difference exists between the actual rotation speed N fed back by the fan and the preset rotation speed N of the fan under the preset power P0 or no signal is fed back by the fan 110, the fan 110 is determined to be in a fault state.
In the embodiment of the present invention, after the operation state of the fan 110 of the refrigerator 100 is obtained and the fan 110 is identified to be in the fault state according to the operation state, the fault type of the fan 110 is determined, a fault elimination policy corresponding to the fault type and pre-configured in the refrigerator 100 is obtained, and the refrigerator 100 is controlled to operate according to the corresponding fault elimination policy, so that the fan 110 can reach a normal state as soon as possible, and the refrigeration effect of the refrigerator 100 is prevented from being affected.
Wherein, the above-mentioned determining the fault type of the fan 110 includes but is not limited to through the following ways: after the predetermined power P0 is input through the PWM control input terminal, if there is a certain rotation speed difference between the actual rotation speed N fed back by the fan 110 and the predetermined rotation speed N of the fan 110 under the predetermined power P0, it is determined that the fault type of the fan 110 is the frosting fault; if the fan 110 does not feed back a signal, it may be determined that the type of fault of the fan 110 is a power failure fault.
Further, the obtaining of the fault elimination policy corresponding to the fault type pre-configured in the refrigerator 100 in step S204 may include: if the fault type is outage, acquiring a fault alarm strategy; and if the fault type is freeze-thaw shutdown, acquiring a fault defrosting strategy.

Among them, an alarm signal may be optionally issued through an alarm device 120 provided on the refrigerator 100 to remind a user of a power failure of the blower fan 110 of the refrigerator 100 to repair it as soon as possible. The temperature of the compartment of the refrigerator 100 is detected to exceed a first set temperature, the compressor 140 and the air door 150 of the refrigerator 100 are controlled to be opened until the temperature of the compartment is lower than a second set temperature, the compressor 140 and the air door 150 are controlled to be closed, and the temperature of the compartment of the refrigerator 100 is maintained through natural convection, so that the problem that the temperature fluctuation of the compartment of the refrigerator 100 is large after a fan is in a power failure fault, and the refrigeration effect of the refrigerator 100 is influenced can be avoided.
In addition, controlling the refrigerator 100 to operate according to the fault defrosting strategy may include: the compressor 140 of the refrigerator 100 is controlled to be turned off and the heating device 130 is controlled to be turned on until the temperature detected by the defrosting sensor of the refrigerator 100 reaches the third set temperature, and the heating device 130 is turned off.
After the frosting fault of the fan 110 is determined, the refrigerator 100 is controlled to operate according to the fault defrosting strategy in time so as to avoid influencing the refrigeration effect, and after the temperature detected by the defrosting sensor reaches the third set temperature, the heating device 130 is turned off so as to avoid causing overhigh temperature of the compartment.
Further, in an embodiment of the present invention, after the heating device 130 is turned off, the method may further include: judging whether the fan 110 is in a fault state; if the fan 110 is in a fault state, controlling the refrigerator 100 to continue to operate according to the fault defrosting strategy until the time length of the refrigerator 100 operating according to the fault defrosting strategy reaches a first set time length; or when the fan 110 is in a normal state, controlling the refrigerator 100 to exit the fault defrosting strategy; if the fan 110 is in a normal state, the refrigerator 100 is controlled to operate according to a normal defrosting strategy. After the refrigerator 100 operates for a preset time period, the compressor 140, the fan 110 and the heating device 130 are controlled to be turned off, and until the defrosting sensor detects that the temperature reaches the preset temperature, the heating device 130 is controlled to be turned off, and the compressor 140 and the fan 110 are controlled to be turned on.
Under the condition that the fan 110 is in the fault state, the refrigerator 100 is controlled to continue to operate according to the fault defrosting strategy until the time that the refrigerator 100 operates according to the fault defrosting strategy reaches the first set time to control the refrigerator 100 to exit the fault defrosting strategy, so that the situation that the temperature of the compartment of the refrigerator 100 is too high due to the fact that the time that the refrigerator 100 operates the defrosting strategy is too long can be prevented.
In an embodiment of the present invention, the controlling the refrigerator 100 to continue operating according to the fault defrosting strategy may include: the defrosting sensor detects that the temperature reaches a fourth set temperature, and controls the heating device 130 to be started; the defrosting sensor detects that the temperature reaches a third set temperature, and controls the heating device 130 to be turned off; and determines whether the blower fan 110 is in a failure state and/or whether the time period in which the refrigerator 100 operates according to the failed defrosting strategy reaches the first set time period each time the heating device 130 is controlled to be turned off, and the fourth set temperature is less than the third set temperature.
The fourth setting temperature may be 18-22 degrees, preferably 20 degrees, the third setting temperature may be 8-12 degrees, preferably 10 degrees, and the third setting temperature and the fourth setting temperature may be set according to actual situations, which is not limited to the present invention.
Wherein, the defrosting sensor detects that the temperature reaches a fourth set temperature, and controls the heating device 130 to be started; the defrosting sensor detects that the temperature reaches a third set temperature, and controls the heating device 130 to be turned off. Cycling through the above steps may avoid excessive temperatures in the compartments of the refrigerator 100.
In an embodiment of the present invention, in order to further avoid the compartment temperature of the refrigerator 100 from being too high, the compressor 140 is controlled to be turned on each time the blower 110 is determined to be in the fault state and the refrigerator 100 is operated according to the fault defrosting strategy for a time period less than a first set time period; the defrosting sensor detects that the temperature reaches the fourth set temperature, and controls the compressor 140 to be turned off.
In addition, in an embodiment of the present invention, after the time period during which the refrigerator 100 operates according to the defrosting fault strategy reaches the first set time period and the refrigerator 100 is controlled to exit from the defrosting fault strategy, the method may further include: judging whether the fan 110 is in a fault state; if the fan 110 is in the fault state, controlling the refrigerator 100 to operate according to a common defrosting strategy, after the operation is performed for a second set time period, judging whether the fan 110 is in the fault state, and if the fan 110 is still in the fault state, controlling the refrigerator 100 to operate according to the fault defrosting strategy again.
Preferably, after the refrigerator 100 operates according to the fault defrosting strategy again, the fault defrosting strategy is exited until the fan 110 is in a normal state.
In fact, when the refrigerator 100 operates according to the fault defrosting strategy for a period of time reaching the first set time period, a part or all of the frost on the fan 110 is ablated, and if it is determined that the fan 110 is still in the fault state at this time, it indicates that a part of the frost still exists on the fan 110. In order to avoid the temperature of the compartment of the refrigerator 100 being too high, at this time, the refrigerator 100 is controlled to enter the normal defrosting strategy, and the refrigerator 100 is controlled to operate according to the normal defrosting strategy for the second set time period, so that the refrigerator 100 can store enough cold energy to cope with the situation that the refrigerator 100 may execute the fault defrosting strategy again. If the refrigerator 100 is judged to be still in the fault state for a long time when operating according to the second setting of the common defrosting strategy, because the frost on the fan 110 is relatively less, the refrigerator 100 is controlled to operate again according to the fault defrosting strategy until the fan 110 is in the normal state, and the fault defrosting strategy is exited, so that the frost can be completely ablated as soon as possible, and the refrigerator 100 can return to the normal refrigeration state as soon as possible.

Step S332: is fan 110 determined to be in a fault condition? If yes, go to step S334; if not, go to step S322;
