Based on the above hardware structure, an embodiment of the control method of the present invention is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the control method of the present invention, the method is used for a refrigerator, and the method comprises the following steps:
step S11: the method comprises the steps that the refrigerator obtains a first operation mode of a refrigerating chamber of the refrigerator;
step S12: when the first operation mode is not a refrigerating chamber defrosting mode, the refrigerator acquires first state information of the refrigerator;
and step S13, when the first state information meets a first preset condition, the refrigerator controls the refrigerating fan to run according to a first preset direction so as to enable the refrigerating chamber to enter a refrigerating chamber defrosting mode.
The execution main body of the invention is a refrigerator installed with a control program, and the refrigerator execution control program is a step for realizing the control method of the invention. A general refrigerator has a refrigerating chamber and a freezing chamber; the refrigerating chamber is provided with a temperature sensor (a refrigerating evaporator) and a refrigerating fan, and the freezing chamber is provided with a temperature sensor (a freezing evaporator), a freezing fan and a freezing defrosting heater.
Generally, the first preset direction refers to a reverse rotation direction of the refrigerating fan, and the second preset direction refers to a forward rotation direction of the refrigerating fan. In the refrigerating mode of the refrigerating chamber, the refrigerating fan rotates forwards to convect the relatively low-temperature air of the refrigerating evaporator to the refrigerating chamber for refrigeration; and when the refrigerating chamber is in a defrosting mode, the refrigerating fan is reversely rotated, and relatively high-temperature air in the refrigerating chamber is convected to the surface of the refrigerating chamber temperature sensor to defrost. Usually, when the refrigerating fan operates, the door of the refrigerating chamber is opened, the refrigerating fan stops, the door of the refrigerating chamber is closed, and the refrigerating fan continues to operate in the original direction.
Generally, a refrigerator also has a control chip, and the control chip controls various sensors to collect state information (temperature and operation time of each sensor, etc.) of the refrigerator and controls the operation of a refrigerating fan, a frost freezing heater, a compressor, a freezing fan, etc. based on the state information. The control chip can be an MCU, and the control chip is used for controlling the refrigerator to output various actions (turning on or off the refrigerating fan, the freezing fan, the compressor and the like, and can also control the refrigerating evaporator and the freezing evaporator to detect the temperature of the refrigerating chamber and the temperature of the freezing chamber of the refrigerator and the like). The temperature of the refrigerating chamber and the temperature of the freezing chamber are changed along with the operation of the refrigerator, the temperature of the refrigerating chamber and the temperature of the freezing chamber are different at different moments, and the obtained temperature of the refrigerating chamber and the obtained temperature of the freezing chamber are also different.
It can be understood that the refrigerating chamber refrigeration mode (in which the refrigerating chamber is cooled and the temperature of the refrigerating chamber is reduced) and the refrigerating chamber defrosting mode (in which the refrigerating chamber temperature sensor of the refrigerating chamber is heated and the refrigerating chamber temperature sensor is defrosted) belong to a periodically alternating working mode, are not always executed, each time the refrigerating chamber refrigeration mode or the refrigerating chamber defrosting mode is operated, there is a corresponding duration, namely a continuous refrigeration duration or a continuous defrosting duration, and meanwhile, other modes exist besides the refrigerating chamber refrigeration mode and the refrigerating chamber defrosting mode, such as a refrigerating chamber drainage mode, a refrigerating chamber sleep-in mode, and the like; similarly, a freezing compartment refrigeration mode (in which the freezing compartment is cooled and the freezing compartment temperature is reduced) and a freezing compartment defrosting mode (in which the freezing compartment temperature sensor of the freezing compartment is heated and the freezing compartment temperature sensor is defrosted) also belong to a periodically alternating operation mode, and there are other modes such as a freezing compartment drainage mode, a freezing compartment sleep mode, and the like. It is understood that the operation mode (the first to sixth operation modes) may refer to one of a refrigerating compartment cooling mode, a refrigerating compartment defrosting mode, a refrigerating compartment drain mode, a freezing compartment cooling mode, a freezing compartment defrosting mode, a freezing compartment drain mode, and the like.
Specifically, the first state information includes a first operation mode of the refrigerating compartment and a second operation mode of the freezing compartment of the refrigerator; the first preset condition includes: the second operation mode is not a freezing chamber defrosting mode, the first operation mode is a refrigerating chamber refrigerating mode, the duration time of the refrigerating chamber refrigerating mode is longer than or equal to a first preset time, and the temperature of the refrigerating chamber is lower than or equal to a first preset temperature; or, the second operation mode is a freezing defrosting mode.
It should be noted that the first status information may also include other information, such as the duration of the cooling mode of the refrigerating compartment, the real-time temperature detected by the temperature sensor of the refrigerating compartment, and the like. According to the control method, when the freezing chamber enters the freezing chamber defrosting mode, the refrigerating chamber also enters the refrigerating chamber defrosting mode; the duration of the refrigerating chamber refrigeration mode refers to the duration of executing the refrigerating chamber refrigeration mode, wherein the first preset duration may be 120 minutes, and a user may set other values according to the needs of the user, which is a preferred duration here, and does not constitute a limitation. The temperature sensor of the refrigerating chamber is a refrigerating evaporator, the temperature of the refrigerating chamber is the temperature collected by the refrigerating evaporator in real time, wherein the first preset temperature can be a certain temperature value in the range of 4-7 ℃, and the invention is not limited.
As can be appreciated, there are two triggering conditions for defrost in the refrigeration compartment, the first: the freezer gets into the freezer mode of defrosting promptly and triggers the walk-in room and gets into the walk-in room mode of defrosting, and the second: the refrigerating chamber is in a refrigerating chamber refrigerating mode, a freezing chamber of the refrigerator is not in a freezing chamber defrosting mode, the duration time of the refrigerating chamber refrigerating mode is longer than or equal to a first preset time, and when the temperature of the refrigerating chamber is smaller than or equal to a first preset temperature, the refrigerating chamber enters the refrigerating chamber defrosting mode.
Further, after the refrigerator acquires the first operation mode of the refrigerating chamber of the refrigerator, the method further comprises the following steps: when the first operation mode is a refrigerating chamber refrigerating mode, the refrigerator acquires a second temperature of the refrigerating chamber temperature sensor; and when the second temperature is greater than or equal to a second preset temperature, the refrigerator controls the refrigerating fan to operate according to a second preset direction so that the refrigerating chamber enters a refrigerating mode of the refrigerating chamber.
It should be noted that, referring to the above description, the second preset direction is the forward rotation direction of the refrigeration fan. The second temperature at this time is the temperature detected by the refrigerating chamber temperature sensor in real time, the second preset temperature is the temperature (refrigerating chamber refrigerating mode starting temperature) triggered to be started in the refrigerating chamber refrigerating mode, the second preset temperature is a variable value and can be changed to a certain extent based on the refrigerating set temperature of the refrigerating chamber, and the second preset temperature is usually 0.5-1 ℃ higher than the refrigerating set temperature.
Further, when the first state information meets a first preset condition, the refrigerator controls the refrigerating fan to run according to a first preset direction so that the refrigerating chamber enters a refrigerating chamber defrosting mode, and the method further comprises the following steps: acquiring a third operation mode of the refrigerating chamber;
when the third operation mode is a refrigerating chamber defrosting mode, second state information of the refrigerator is obtained, and when the second state information meets a second preset condition, a refrigerating fan is controlled to be turned off so that the refrigerating chamber exits the refrigerating chamber defrosting mode;
or when the third operation mode is a refrigerating chamber refrigeration mode, the temperature of the refrigerating chamber is obtained, and when the temperature of the refrigerating chamber is less than or equal to a third preset temperature and the temperature of the refrigerating chamber is greater than or equal to a fourth preset temperature, the refrigerating fan is controlled to be turned off so that the refrigerating chamber exits the refrigerating chamber refrigeration mode.
It should be noted that the temperature of the refrigerating chamber is the temperature detected by the temperature sensor of the refrigerating chamber in real time, the third preset temperature is the temperature (the shutdown temperature of the refrigerating chamber in the refrigerating mode) for triggering the exit of the refrigerating chamber in the refrigerating mode, and the third preset temperature is also a variable value and is usually 1.5-2 ℃ lower than the second preset temperature. The fourth preset temperature is also a variable value, and can have different values along with different situations, and different fourth preset temperatures are required to be set for ensuring that the defrosting effect of the refrigerating chamber temperature sensor is better and different environmental temperatures are required, wherein the environmental temperature is the real-time environmental temperature detected by the environmental temperature sensor of the refrigerator.
For example, the ambient environmental temperature is less than 7 ℃, and the fourth preset temperature is-40 ℃; when the ambient temperature is 7-12 ℃, the refrigeration set temperature is 2-4 ℃ (the refrigeration set temperature is usually an integer, and all the refrigeration set temperatures referred to herein are integers), and the fourth preset temperature is 0.5 ℃; when the ambient temperature is 7-12 ℃, the refrigeration set temperature is 5-8 ℃, and the fourth preset temperature is 2.5 ℃; when the ambient temperature is 12-28 ℃, the refrigeration set temperature is 2-5 ℃, and the fourth preset temperature is 1 ℃ lower than the refrigeration set temperature; when the ambient temperature is 12-28 ℃, the refrigeration set temperature is 6-8 ℃, and the fourth preset temperature is 2 ℃ lower than the refrigeration set temperature; when the ambient temperature is higher than 28 ℃, the fourth preset temperature is the refrigeration set temperature. Under the above different environmental temperatures, the corresponding third preset temperature and the second preset temperature will also change, and usually the second preset temperature is 0.5-1 ℃ higher than the refrigeration set temperature, and the third preset temperature is 1.5-2 ℃ lower than the second preset temperature, which will not be described herein again.
Further, the second state information includes a fourth operation mode of the freezing chamber;
the second preset condition includes: the fourth operation mode is not a freezing chamber defrosting mode, the temperature sensor is normal, and the temperature of the refrigerating chamber is not less than the fifth preset temperature or the duration of the refrigerating chamber defrosting mode is not less than the second preset duration.
It should be noted that the second status information may also include other information, such as the real-time detected temperature of the refrigeration compartment temperature sensor. The temperature of the refrigerating chamber is the real-time detection temperature of the refrigerating chamber temperature sensor, the fifth preset temperature is usually a certain value of 4-7 ℃, the duration time is the continuous operation time of the refrigerating chamber defrosting mode, and the second preset time can be 30 minutes. Normally, after the refrigerating chamber defrosting mode is exited, the refrigerating chamber drainage mode is entered, the duration of the refrigerating chamber drainage mode is 5 minutes, and after the refrigerating chamber drainage mode is ended, whether the refrigerating chamber refrigeration mode or the sleep-mode is entered or not is determined based on specific operation state information.
Further, in another embodiment, the second preset condition includes: the fourth operation mode is a freezing chamber defrosting mode, the ambient temperature is higher than the preset ambient temperature, the refrigerating chamber temperature sensor is normal, the temperature of the refrigerating chamber is not lower than the sixth preset temperature, or the duration of the refrigerating chamber defrosting mode is not lower than the third preset duration.
It should be noted that, at this time, the freezing chamber is in the freezing chamber defrosting mode, and the refrigerating chamber is also in the refrigerating chamber defrosting mode, and the freezing chamber and the refrigerating chamber are defrosted together. The temperature of the refrigerating chamber is the detection temperature of the refrigerating chamber temperature sensor, the sixth preset temperature is usually 8 ℃, the preset environment temperature is usually 20 ℃, the duration is the continuous operation duration of the refrigerating chamber defrosting mode, the third preset duration is usually 4 hours, and the starting point of the duration timing is the starting of the freezing chamber defrosting mode due to the fact that the refrigerating chamber defrosting mode and the freezing chamber defrosting mode are triggered together.
Generally, when the refrigerating chamber defrosting mode and the freezing chamber defrosting mode are triggered together, after the refrigerating chamber defrosting mode is finished, the refrigerating chamber drainage mode lasting for 5 minutes is started, after the refrigerating chamber drainage mode is finished, the refrigerating fan continues to operate according to a second preset direction, so that the temperature detected by the refrigerating chamber temperature sensor is not greater than a third preset temperature (refrigerating chamber refrigeration mode shutdown temperature), and then the normal refrigerating chamber refrigeration mode is started.
Further, in another embodiment, the second preset condition includes: the fourth operation mode is a freezing chamber defrosting mode, the environment temperature is not more than the preset environment temperature, the refrigerating chamber temperature sensor is normal, and the temperature of the refrigerating chamber is not less than the seventh preset temperature or the duration of the refrigerating chamber defrosting mode is not less than the fourth preset duration.
It should be noted that, at this time, the freezing chamber is in the freezing chamber defrosting mode, and the refrigerating chamber is also in the refrigerating chamber defrosting mode, and the freezing chamber and the refrigerating chamber are defrosted together. The temperature of the refrigerating chamber is the detection temperature of the refrigerating chamber temperature sensor, the seventh preset temperature is usually 8 ℃, the preset environment temperature is usually 20 ℃, the duration is the continuous operation duration of the refrigerating chamber defrosting mode, the fourth preset duration is usually 6 hours, and the starting point of the duration timing is the starting of the freezing chamber defrosting mode due to the fact that the refrigerating chamber defrosting mode and the freezing chamber defrosting mode are triggered together.
Generally, when the refrigerating chamber defrosting mode and the freezing chamber defrosting mode are triggered together, after the refrigerating chamber defrosting mode is finished, the refrigerating chamber drainage mode lasting for 5 minutes is entered, after the refrigerating chamber drainage mode is finished, the refrigerating fan continues to operate according to a second preset direction (forward rotation direction), so that the temperature detected by the refrigerating chamber temperature sensor is not greater than a third preset temperature (refrigerating chamber refrigeration mode shutdown temperature), and then the normal refrigerating chamber refrigeration mode is entered.
Further, in another embodiment, the second preset condition includes: the third operation mode is a freezing chamber defrosting mode, and when the refrigerating chamber temperature sensor is abnormal, the duration of the refrigerating chamber defrosting mode reaches a fifth preset duration.
It should be noted that, at this time, the refrigerating chamber temperature sensor is abnormal, and the actual temperature cannot be detected; the duration is the continuous running time of the refrigerating chamber defrosting mode, and the fifth preset time is usually the longest period of the refrigerating chamber defrosting mode.
Generally, when the refrigerating chamber defrosting mode and the freezing chamber defrosting mode are triggered together, after the refrigerating chamber defrosting mode is finished, the refrigerating chamber drainage mode lasting for 5 minutes is entered, and after the refrigerating chamber drainage mode is finished, the normal refrigerating chamber refrigerating mode is entered. If the freezing chamber is still in the freezing chamber defrosting mode after the water drainage mode of the refrigerating chamber is finished, the refrigerating chamber does not enter the refrigerating chamber refrigerating mode and the refrigerating chamber defrosting mode (refrigerating chamber dormant mode), and the refrigerating chamber does not continue to enter the normal refrigerating chamber refrigerating mode until the freezing chamber defrosting mode of the freezing chamber is finished.
Further, in another embodiment, before the refrigerator acquires the first operation mode of the refrigerating chamber of the refrigerator, the method further comprises: the refrigerator acquires the operation information of the compressor, a fifth operation mode of the refrigerating chamber and a sixth operation mode of the freezing chamber;
when the operation information of the compressor is that the compressor is closed, the fifth operation mode is not a refrigerating chamber defrosting mode, and the sixth operation mode is not a freezing chamber defrosting mode, the refrigerator acquires the temperature of the refrigerating chamber, and controls the compressor to start when the temperature of the refrigerating chamber is greater than or equal to a second preset temperature and the temperature of the refrigerating chamber is greater than or equal to an eighth preset temperature;
or when the operation information of the compressor is that the compressor is closed and the sixth operation mode is not the freezing chamber defrosting mode, the refrigerator acquires the temperature of the freezing chamber, and when the temperature of the freezing chamber is greater than or equal to the ninth preset temperature, the refrigerator controls the compressor to start;
or when the operation information of the compressor is that the compressor is started and the sixth operation mode is a freezing chamber defrosting mode, the refrigerator controls the compressor to be closed;
or when the operation information of the compressor is that the compressor is started, the refrigerator acquires the temperature of the freezing chamber, and controls the compressor to be closed when the temperature of the freezing chamber is less than or equal to the tenth preset temperature and the fifth operation mode is not the refrigerating chamber refrigeration mode.
It should be noted that the freezing chamber temperature sensor is a freezing evaporator, the temperature of the freezing chamber is detected by the freezing chamber temperature sensor, the seventh preset temperature is usually 2 ℃, and the ninth preset temperature is usually the temperature at which the freezing chamber refrigeration mode is triggered to start (the starting temperature of the freezing chamber refrigeration mode).
Meanwhile, the tenth preset temperature is the temperature at which the freezing chamber refrigeration mode triggers exit (freezing chamber refrigeration mode shutdown temperature), and meanwhile, the refrigerating chamber can be turned off without a refrigerating chamber refrigeration mode (the refrigerating chamber is already in a cold storage chamber refrigeration mode, and the refrigerating chamber refrigeration mode is not needed temporarily).
When the compressor is started, the compressor is used for performing a freezing chamber refrigeration mode on a freezing chamber or performing a refrigerating chamber refrigeration mode on a refrigerating chamber, namely, the compressor cannot be turned off when the freezing chamber is in the freezing chamber refrigeration mode or the refrigerating chamber is in the refrigerating chamber refrigeration mode; when the compressor is stopped, the refrigerating compartment does not need to be in a refrigerating compartment refrigeration mode, and the freezing compartment does not need to be in a freezing compartment refrigeration mode.
Further, the refrigerator has a temperature-variable chamber; after controlling the compressor to start, the method further comprises: acquiring the continuous operation time of the compressor; when the continuous operation time length exceeds the preset operation time length, acquiring the temperature of the refrigerating chamber, the temperature of the freezing chamber and the temperature of the temperature-changing chamber; and when the temperature of the refrigerating chamber is higher than the eleventh preset temperature, the temperature of the freezing chamber is higher than the twelfth preset temperature or the temperature of the temperature-changing chamber is higher than the thirteenth preset temperature, controlling the freezing chamber to enter a freezing chamber defrosting mode.
The refrigerator is also provided with a temperature-variable chamber, and a temperature-variable chamber evaporator of the temperature-variable chamber is a temperature-variable chamber temperature sensor of the temperature-variable chamber; the preset operation time can be 4 hours; the temperature of the refrigerating chamber, the temperature of the freezing chamber and the temperature of the temperature-changing chamber are respectively real-time temperatures detected by a refrigerating chamber temperature sensor, a freezing chamber temperature sensor and a temperature-changing chamber temperature sensor, the eleventh preset temperature can be 2 ℃ higher than the temperature corresponding to the lowest gear of the refrigerating chamber, the twelfth preset temperature can be 2 ℃ higher than the temperature corresponding to the lowest gear of the freezing chamber, and the thirteenth preset temperature can be 2 ℃ higher than the temperature corresponding to the lowest gear of the temperature-changing chamber.
When the refrigerator is in the refrigerating chamber defrosting mode, the refrigerating chamber is driven to enter the refrigerating chamber defrosting mode. In order to avoid incomplete defrosting, for example, an air return opening of a freezing chamber has residual frost, a freezing evaporator cannot defrost cleanly, and the like, so that when the continuous operation time of a compressor exceeds the preset operation time, the temperatures of a refrigerating chamber temperature sensor, a freezing chamber temperature sensor and a temperature-changing chamber temperature sensor are detected, and when the temperature detection result is that the temperature of the refrigerating chamber is greater than the eleventh preset temperature, the temperature of the freezing chamber is greater than the twelfth preset temperature or the temperature of the temperature-changing chamber is greater than the thirteenth preset temperature, the freezing chamber is controlled to enter a freezing chamber defrosting mode, so that the refrigerating chamber and the temperature-changing chamber are driven to enter corresponding defrosting modes.
The variable-temperature chamber refrigeration mode and the variable-temperature chamber defrosting mode of the refrigerator variable-temperature chamber refer to the refrigerating chamber refrigeration mode and the refrigerating chamber defrosting mode of the invention, and are not described again; in other embodiments, the refrigerator variable temperature chamber may have a variable temperature chamber defrosting heater for performing a variable temperature chamber defrosting mode on the variable temperature chamber.
In other embodiments, the refrigerator may have other types of compartments in addition to the refrigerating compartment, the freezing compartment, and the warming compartment. The compartments other than the freezing compartment can be refrigerated according to the refrigerating compartment refrigeration mode of the refrigerating compartment of the invention, and the defrosting is performed according to the refrigerating compartment defrosting mode of the refrigerating compartment of the invention.
The technical scheme of the invention provides a control method for a refrigerator, wherein the refrigerator comprises a refrigerating fan and comprises the following steps: acquiring a first operation mode of a refrigerating chamber of the refrigerator; when the first operation mode is not a refrigerating chamber defrosting mode, acquiring first state information of the refrigerator; and when the first state information meets a first preset condition, controlling the refrigerating fan to operate according to a first preset direction so as to enable the refrigerating chamber to enter a refrigerating chamber defrosting mode. Because the control method of the invention controls the refrigerating fan to operate according to the first preset direction, so that the refrigerating chamber enters the refrigerating chamber defrosting mode, and the refrigerating chamber does not need to be controlled to enter the refrigerating chamber defrosting mode by controlling the refrigerating defrosting heating wire, the refrigerator does not need to be provided with the refrigerating defrosting heating wire, and can also carry out defrosting treatment on the refrigerating chamber, and the cost of the refrigerator is lower.
