The control unit is used for controlling the opening and closing of the first air door and the second air door and the power of the refrigerating unit. The refrigerator realizes the accurate control of the temperature of a first chamber and a second chamber of the refrigerator by controlling the power of a refrigeration unit and the opening degree of a first air door and a second air door, and the specific control method of the refrigerator comprises the following steps:
S1: the first compartment has a first refrigeration state, the preset temperature of the first compartment is a first temperature T01 when the first compartment is in the first refrigeration state, the second compartment has a second refrigeration state, and the preset temperature of the second compartment is a second temperature T02 when the second compartment is in the second refrigeration state.
S2: the first temperature sensor detects a temperature T1 of the first compartment, the second temperature sensor detects a temperature T2 of the second compartment if the detected temperature is higher than a first temperature T01, the process proceeds to step S3 if the detected temperature is higher than a second temperature T02, and the process proceeds to step S4 if not.
S3: and detecting whether the refrigeration unit works, if the refrigeration unit works, entering step S3a, and if the refrigeration unit does not work, entering step S3 b.
s3 a: the working power of the refrigeration unit is improved, the refrigeration unit works for a period of time, the first temperature sensor detects the temperature T1 of the first compartment and the temperature T2 of the second compartment, and if T1 is not more than T01 and T2 is not more than T02, the first air door and the second air door are closed, and the refrigeration unit is controlled to stop working; and if T1 is not less than T01, T2 is greater than T02, closing the first air door, controlling the refrigeration unit to continue working for a period of time until T2 is not less than T02, closing the first air door and the second air door, and controlling the refrigeration unit to stop working. Of course, in other embodiments, in addition to increasing the operating power of the refrigeration unit, the opening degrees of the first damper and the second damper may be adjusted appropriately according to the difference between the detected temperatures of the first compartment and the second compartment and the first temperature and the detected second temperature, so as to ensure that the temperatures of the first compartment and the second compartment are reduced relatively stably.
s3 b: opening a first air door and a second air door, controlling the refrigeration unit to work for a period of time, detecting the temperature T1 of the first compartment and the temperature T2 of the second compartment by the first temperature sensor, if T1 is not more than T01 and T2 is not more than T02, closing the first air door and the second air door, and controlling the refrigeration unit to stop working; and if T1 is not less than T01, T2 is greater than T02, closing the first air door, controlling the refrigeration unit to continue working for a period of time until T2 is not less than T02, closing the first air door and the second air door, and controlling the refrigeration unit to stop working.
S4: and detecting whether the refrigeration unit works, if the refrigeration unit works, entering step S4a, and if the refrigeration unit does not work, entering step S4 b.
s4 a: reducing the opening degree of the second air door and/or increasing the opening degree of the first air door, controlling the refrigerating unit to work for a period of time after increasing the working power of the refrigerating unit, and if T1 is less than or equal to T01, reducing the working power of the refrigerating unit, increasing the opening degree of the second air door and/or reducing the opening degree of the first air door; and if T1 is greater than T01, further reducing the opening degree of the second air door and/or increasing the opening degree of the first air door, increasing the working power of the refrigeration unit, controlling the refrigeration unit to work for a period of time until T1 is less than or equal to T01, reducing the working power of the refrigeration unit, and increasing the opening degree of the second air door and/or reducing the opening degree of the first air door.
If the first compartment temperature rises and the second compartment temperature does not change, simply increasing the opening of the first damper may cause a problem that the second compartment is insufficiently cooled, and simply increasing the power of the cooling unit may cause a sudden decrease in the second compartment temperature. Therefore, in this embodiment, the power of the refrigeration unit needs to be increased firstly, and then the opening degrees of the first air door and the second air door are correspondingly adjusted, so that the temperature of the first compartment is further reduced on the basis of ensuring that the refrigeration condition of the second compartment is not changed, the temperature of the first compartment reaches the preset temperature as soon as possible, and the rapid refrigeration of the first compartment is realized.
s4 b: opening a first air door, controlling the refrigeration unit to work for a period of time, detecting the temperature T1 of a first compartment by the first temperature sensor, if T1 is less than or equal to T01, closing the first air door, and stopping the refrigeration unit; if T1 is greater than T01, the refrigeration unit is controlled to continue to work for a period of time until T1 is less than or equal to T01, and the first air door is closed.
The refrigerator of the invention can also adjust the refrigeration type of the first compartment or the second compartment by adjusting the size of the first air door or the second air door, and the refrigeration type of the first compartment or the second compartment is as follows:
The first compartment also has a third refrigeration state with the temperature lower than that of the first refrigeration state, and when the first compartment is changed from the first refrigeration state to the third refrigeration state, the opening degree of the first air door is increased, and the power of the refrigeration unit and the opening degree of the second air door are correspondingly required to be changed.
In this embodiment, the first refrigeration state of the first compartment is a cold storage state, and the third refrigeration state is a soft freezing state; the second compartment has a second refrigerated state that is a frozen state, and the second compartment may also have a soft frozen state and a refrigerated state.
When the refrigerating compartment is switched between different refrigerating states, the first damper and the second damper work in coordination, and the embodiment takes the example that the first compartment is switched from the refrigerating state to the soft freezing state as an example.
When the first compartment is changed from the cold storage state to the soft freezing state, the opening degree of the first air door needs to be increased firstly, if the temperature of the first compartment does not reach the temperature of the soft freezing state after a period of time, the opening degree of the first air door can be further increased, and if the opening degree of the first air door reaches the maximum value, the power of the refrigeration unit can be increased and the opening degree of the second air door can be reduced.
In addition, the refrigerator of the embodiment may further include a heating device in the first air duct and/or the second air duct, so that when the refrigeration compartment is switched from the high refrigeration state to the low refrigeration state, the corresponding heating device may be turned on, so that the refrigeration compartment may reach the corresponding refrigeration state as soon as possible. The heating device is arranged in the first air duct and/or the second air duct, but not in the refrigerating compartment, so as to prevent the heating device from scalding a user.
According to the control method of the refrigerator and the refrigerator, the working state of the refrigerating unit and the opening and closing of the first air door and the second air door are changed, so that the temperature can be accurately controlled and the refrigerator can be rapidly refrigerated when the temperature of the refrigerator compartment is increased or the refrigerating state is changed.
although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
