Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart illustrating a method for controlling a parallel dual system refrigerator according to an embodiment of the present invention. In fig. 1, the control method may include:
in step S10, the current circulation mode of the refrigerator is determined.
In step S11, if it is determined that the current circulation mode of the refrigerator is one of the refrigerating circulation mode and the freezing circulation mode, the operation time of the one (the determined refrigerating circulation mode or freezing circulation mode) is determined.
In step S12, it is determined whether the operation time is greater than or equal to the maximum operation time.
In step S13, in the case where it is judged that the operation time is less than the maximum operation time, it is determined whether the current refrigerator satisfies the one of the termination conditions.
In step S14, in the case where it is judged that the operation time is greater than or equal to the maximum operation time/the refrigerator satisfies the termination condition of one, it is determined whether the refrigerator satisfies the start condition of the other of the refrigerating cycle mode and the freezing cycle mode.
In step S15, in case that it is judged that the refrigerator satisfies the activation condition of the other, the other is activated, the current circulation mode of the refrigerator is determined again, and the corresponding steps of the control method are performed (i.e., it returns to perform step S10).
In this embodiment, step S13 is to determine whether the refrigerator has satisfied the termination condition in any circulation mode at this time, in the case where the operation time of the refrigerator to perform the circulation mode has not reached the maximum operation time of the compressor. In the case where the refrigerator has satisfied the termination condition, which means that the circulation mode does not need to be continuously executed, the step S14 is performed instead, i.e., it is determined whether the refrigerator satisfies the start condition of another circulation mode. On the contrary, if the refrigerator does not satisfy the termination condition at this time, the current circulation mode may be continuously performed while continuing to perform step S12, i.e., determining whether the operation time is greater than or equal to the maximum operation time until the operation time is greater than or equal to the maximum operation time.
Specifically, in this embodiment, taking the current circulation mode (one) as the refrigeration circulation mode as an example, the step S13 may specifically include the steps shown in fig. 2. In fig. 2, the step S13 may include:
in step S20, the temperature of the refrigerating compartment of the refrigerator is acquired;
in step S21, it is determined whether the temperature of the refrigerating compartment is less than or equal to a refrigerating compartment shutdown temperature;
in the case where it is determined that the temperature of the refrigerating compartment is less than or equal to the refrigerating compartment shutdown temperature in step S22, it is determined that the current refrigerator satisfies the termination condition of the refrigerating cycle mode, and then step S14 may be performed, i.e., it is determined whether the temperature of the freezing compartment of the refrigerator is greater than the freezing compartment startup temperature.
In step S23, in case that it is judged that the temperature of the refrigerating compartment is greater than the refrigerating compartment shutdown temperature, it is determined that the current refrigerator does not satisfy one of the termination conditions, and then it may return to perform step S12.
And if the current cycle mode (one) is taken as the freezing cycle mode as an example, the step S13 may specifically include the steps as shown in fig. 3. In fig. 3, the step S13 may include:
in step S30, the temperature of the freezer compartment of the refrigerator is acquired;
in step S31, it is determined whether the temperature of the freezing compartment is less than or equal to the freezing compartment stop temperature;
in the case where it is determined that the temperature of the freezing compartment is less than or equal to the freezing compartment stopping temperature in step S32, it is determined that the current refrigerator satisfies the termination condition of the freezing cycle mode, and then step S14 may be performed, i.e., it is determined whether the temperature of the refrigerating compartment of the refrigerator is greater than the refrigerating compartment starting temperature.
In step S33, in the case where it is determined that the temperature of the freezing compartment is greater than the freezing compartment stopping temperature, it is determined that the current refrigerator does not satisfy the termination condition of the freezing cycle mode, and then it may return to perform step S12.
In this embodiment, step S14 is to determine whether one needs to be started (as opposed to another loop pattern of one) in the case where the other is working. In case that another needs to be started (i.e. the refrigerator meets the starting condition of another), step S15 can be executed directly, that is, the other is started, so that the operation of another circulation mode can be considered at intervals (maximum operation time) during the operation of any circulation mode.
Whereas, in case the refrigerator does not satisfy the starting condition of the other one, different methods may be respectively performed for the two cases from step S12 to step S14 and from step S13 to step S14.
Specifically, step S12 to step S14 are exemplified. In step S12, since the operation time reaches the maximum operation time, step S13 is skipped to directly perform step S14 (i.e., it is not determined whether the refrigerator satisfies one of the termination conditions at this time). In this case, if the current refrigerator cannot satisfy the start condition of the other one, and it is not known whether the refrigerator satisfies the end condition of the one at this time, it may return to perform step S13, i.e., to re-determine whether the refrigerator satisfies the end condition of the one.
More specifically, in the case where the one is the refrigeration cycle mode:
step S12 is to determine whether the operation time of the refrigeration cycle mode is greater than or equal to the maximum operation time, and in step S12, the determination result is that the operation time is greater than or equal to the maximum operation time;
step S14 may be to obtain the temperature of the freezing compartment of the refrigerator and determine whether the temperature of the freezing compartment is less than the starting temperature of the freezing compartment when the operation time of the refrigeration cycle mode is determined to be greater than or equal to the maximum operation time.
In the case where it is determined in step S14 that the temperature of the freezing compartment is less than the starting temperature of the freezing compartment, it is not necessary to perform the freezing cycle mode at this time, and therefore it may be returned to step S13 to obtain the temperature of the refrigerating compartment of the refrigerator and determine whether the temperature of the refrigerating compartment is less than or equal to the stopping temperature of the refrigerating compartment. If the temperature of the refrigerating chamber is judged to be higher than the refrigerating chamber shutdown temperature, the refrigerating circulation mode needs to be continuously executed. Therefore, execution of step S12 may be returned to.
Conversely, in the case where the one is the refrigeration cycle mode:
step S12 is to determine whether the operation time of the refrigeration cycle mode is greater than or equal to the maximum operation time, and in step S12, the operation time is greater than or equal to the maximum operation time;
step S14 may be to obtain the temperature of the refrigerating compartment of the refrigerator and determine whether the temperature of the refrigerating compartment is less than the refrigerating compartment startup temperature when the operation time of the freezing cycle mode is determined to be greater than or equal to the maximum operation time.
In the case where it is determined at step S14 that the temperature of the refrigerating compartment is less than the refrigerating compartment starting temperature, the refrigerating cycle mode need not be performed at this time, and thus it may be returned to step S13 to obtain the temperature of the freezing compartment of the refrigerator and determine whether the temperature of the freezing compartment is less than or equal to the freezing compartment stopping temperature. If the temperature of the freezing chamber is judged to be higher than the stop temperature of the freezing chamber, the freezing circulation mode needs to be continuously executed. Therefore, execution of step S12 may be returned to.
In the case of steps S13 to S14, since steps S12, S13 and S14 have passed, the description operating time does not reach the maximum operating time, and it is determined that the current refrigerator satisfies the termination condition of one that does not need to be continued through step S13. Therefore, in this step S14, if it is judged that the refrigerator does not satisfy the starting condition of the other, it is explained that the refrigerator does not need to instruct any of the two circulation modes at this time, and it is possible to perform the control of the compressor stop.
More specifically, in the case where the one is the refrigeration cycle mode:
step S12 is to determine whether the operation time of the refrigeration cycle mode is greater than or equal to the maximum operation time, and in step S12, the operation time is less than the maximum operation time;
step S13 may be to obtain the temperature of the freezer compartment of the refrigerator and determine whether the temperature of the freezer compartment is less than or equal to the freezer compartment shutdown temperature in case that the operation time is determined to be less than the maximum operation time;
step S14 may be to obtain the temperature of the refrigerating compartment of the refrigerator and determine whether the temperature of the refrigerating compartment is less than the refrigerating compartment startup temperature in case that the temperature of the freezing compartment is determined to be less than or equal to the freezing compartment shutdown temperature (which indicates that the freezing cycle mode does not need to be continued).
In the case that it is determined in step S14 that the temperature of the refrigerating compartment is lower than the refrigerating compartment startup temperature, this indicates that the refrigerator does not need to start the freezing cycle mode nor the refrigerating cycle mode. The compressor can thus be controlled to shut down.
Conversely, in the case where the one is the refrigeration cycle mode:
step S12 is to determine whether the operation time of the refrigeration cycle mode is greater than or equal to the maximum operation time, and in step S12, the operation time is less than the maximum operation time;
step S13 may be to obtain the temperature of the refrigerating compartment of the refrigerator when the operation time is determined to be less than the maximum operation time, and determine whether the temperature of the refrigerating compartment is less than or equal to the refrigerating compartment shutdown temperature;
step S14 may be to obtain the temperature of the freezing compartment of the refrigerator and determine whether the temperature of the freezing compartment is less than the starting temperature of the freezing compartment in case that the temperature of the refrigerating compartment is determined to be less than or equal to the stopping temperature of the refrigerating compartment (which indicates that the refrigerating cycle mode does not need to be continuously performed).
In the case that it is determined in step S14 that the temperature of the freezing compartment is lower than the starting temperature of the freezing compartment, this indicates that the refrigerator does not need to start the refrigerating cycle mode nor the freezing cycle mode. The compressor can thus be controlled to shut down.
In this embodiment, the insulation requirements of the refrigerating and freezing compartments of the refrigerator are taken into account. Since the temperature of the refrigerating chamber is high relative to the temperature of the freezing chamber in a normal state. When the cold room and the freezer room are both above the starting point temperature, the freezer room has a longer shelf life than the cold room due to the temperature difference between the two. Therefore, during the selective starting of the refrigerating cycle mode and the freezing cycle mode, the refrigerating cycle mode can be started with priority. Specifically, the control method may further include the following steps:
step 1, acquiring the temperature of a refrigerating chamber and the temperature of a freezing chamber of a refrigerator;
and 2, judging whether a refrigeration cycle mode/freezing cycle mode needs to be started or not according to the temperature of the refrigerating chamber and the temperature of the freezing chamber. Specifically, the specific basis for judging whether the refrigeration cycle mode/freezing cycle mode needs to be started may be to judge whether the temperature of the refrigerating chamber/freezing chamber of the current refrigerator meets the starting condition of the refrigeration cycle mode/freezing cycle mode;
step 3, under the condition that the refrigerator is judged to need to start the refrigeration cycle mode and does not need to start the freezing cycle mode, starting the refrigeration cycle mode;
step 4, starting the freezing circulation mode under the condition that the refrigerator is judged to need to start the freezing circulation mode and does not need to start the refrigerating circulation mode;
and 5, starting the refrigeration cycle mode under the condition that the refrigeration cycle mode and the freezing cycle mode need to be started by the refrigerator.
In another aspect, the present invention also provides a parallel dual system refrigerator, which may include a refrigerating chamber sensor 01, a freezing chamber sensor 02, a compressor 03, an electromagnetic valve 04, and a controller 05, as shown in fig. 4. Specifically, in this fig. 4, the refrigerating compartment sensor 01 may be used to acquire the temperature of the refrigerating compartment of the refrigerator. The freezing chamber sensor 02 may be used to acquire the temperature of the freezing chamber of the refrigerator. The compressor 03 is used for starting to make the refrigerator enter a refrigerating cycle mode or a freezing cycle mode. The solenoid valve 04 may be connected to the compressor 03 for controlling selection of the refrigerating cycle mode or the freezing cycle mode. The controller 05 may be configured to perform a control method as described in any one of the above to control the above-described refrigerating chamber sensor 01, freezing chamber sensor 02, compressor 03, and electromagnetic valve 04.

The freezing evaporator 12 and the freezing capillary tube 14 may be provided in a freezing chamber of a refrigerator for adjusting the temperature of the freezing chamber. A dry filter 15 and a condenser 16 may be used to remove water vapor from the refrigeration circuit.
