Description

Refrigerator control method, storage medium and refrigerator

Technical Field

The application belongs to the technical field of refrigerators, and particularly relates to a control method of a refrigerator, a storage medium and the refrigerator.

Background

Experiments show that when the refrigerating and freezing cycle of the refrigerator is 1:1 and the refrigerating and freezing chambers begin to refrigerate at the same time, the energy consumption test result is good. Further, the compressor has longer running time and better energy consumption test result, because the compressor is started each time to reestablish the system balance, and the wasted power consumption is more in a period of time. If the operation time of the compressor is to be prolonged, the reduction of the rotation speed of the compressor is a first optimization direction, but 1: under the period 1, the refrigerating start-stop period is shorter due to the limitation of the temperature fluctuation range of the refrigerating chamber, so that the further downward detection possibility of the rotating speed is limited in advance.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

The existing single-system multi-temperature-control air-cooled refrigerator can be summarized as follows: when the temperature of the freezing chamber reaches a starting point, controlling the compressor and the fan to be started; when the temperature of the refrigerating chamber reaches a starting point, controlling a fan and a refrigerating air door to be opened; when the temperature of the refrigerating chamber reaches a stop point, controlling the refrigerating air door to be closed; and when the temperature of the freezing chamber reaches the stop point and the temperature of the refrigerating chamber reaches the stop point at least once and is smaller than the temperature of the starting point, the fan of the compressor is controlled to be closed. It will be appreciated that under this rule, the refrigeration cycles of the refrigerating and freezing compartments are largely unsynchronized, and the random coupling of the refrigeration starts of the compartments is likely, so that the energy consumption level of the refrigerator is not the highest. The rule found by the test is that, in the stage of stopping the compressor, if the refrigeration is started first, the energy consumption can be increased by about 5%, the refrigeration is started with a little delay, the starting time of the compressor is longer and the energy consumption can be increased at the same rotating speed, and if the refrigeration and the freezing are synchronously started, the energy consumption level of the compressor is optimal.

In view of the foregoing, an embodiment of the present application provides a refrigeration method of a refrigerator, and referring to fig. 1, for an exemplary embodiment, fig. 1 is a flowchart of the refrigeration method of the refrigerator provided in the embodiment of the present application. The refrigerating method of the refrigerator is performed by, for example, a controller of the refrigerator, and includes the following steps S101 to S109:

step S101: after the refrigerator is electrified, judging the temperature LC of the refrigerating chamber _c Whether or not it is greater than or equal to the refrigerating chamber start-up point temperature T _con ；

In the initial state, the refrigerating chamber and the freezing chamber of the refrigerator are not refrigerated. It will be appreciated that if the compartment is in the open cooling mode, the compartment temperature will gradually decrease, and if the compartment is in the closed cooling mode, the refrigerator temperature may gradually increase due to ambient temperature, door opening, etc.

The refrigerating chamber temperature LC _c A temperature greater than or equal to the start point of the refrigerator indicates that the refrigerator's refrigerator compartment requires a cooling mode to cool, corresponding to a refrigerator compartment temperature LC _c The reduction to the temperature at which the cool down point is reached indicates that the cool down of the cool down chamber of the refrigerator is not needed, at which time the cool down of the cool down chamber can be turned off.

The temperature of the start/stop point of the refrigerating chamber is calculated by the controller according to the ambient temperature and a corresponding preset calculation formula. Exemplary, refrigerator compartment start-up Point temperature T _con The temperature is 5 ℃ higher than the shutdown point of the refrigerating chamber.

If the temperature LC of the refrigerating chamber _c Has reached the starting point temperature T of the refrigerating chamber _con The following step S103 is performed; refrigerating compartment temperature LC _c Not reaching the starting point temperature T of the refrigerating chamber _con The following step S102 is performed.

Step S102: judging freezing chamber temperature LD _c Whether or not it is greater than or equal to the freezing chamber start-up point temperature T _don ；

Likewise, freezing chamber temperature LD _c A temperature greater than or equal to the starting point of the freezing chamber indicates that the freezing chamber of the refrigerator needs to be opened to cool down in a refrigeration mode, and correspondingly, the temperature LD of the freezing chamber _c The temperature decreasing to the freezing chamber shutdown point indicates that the freezing chamber of the refrigerator does not need to continue to refrigerate, and at this time, the freezing chamber can be closed for refrigeration.

If the temperature LD of the freezing chamber _c Has reached the starting point temperature T of the freezing chamber _don The following step S103 is performed; freezing chamber temperature LD _c Not reaching the starting point temperature T of the freezing chamber _don The process returns to step S101.

It can be appreciated that the freezing chamber temperature LD can also be judged first _c After judging the temperature LC of the refrigerating chamber _c And the temperature of any compartment reaches the corresponding starting point temperature, and the refrigeration mode of the refrigerator is started.

Step S103: controlling the refrigerating chamber and the freezing chamber to start a refrigerating mode;

the refrigerator further includes a refrigeration system including a compressor and an evaporator, the evaporator is disposed in a freezing air duct of the refrigerator, the freezing air duct is communicated with the freezing chamber, a refrigeration air door is disposed between the freezing air duct and the refrigeration chamber, and when the refrigeration air door is opened, the freezing air duct is communicated with the refrigeration chamber. A fan is also arranged in the freezing air duct, for example. When the compressor works, the evaporator can cool the air in the freezing air duct, and the refrigerating chamber and the freezing chamber can refrigerate internal articles by carrying out air convection with the freezing air duct. Therefore, the refrigerating mode of the refrigerating chamber and the freezing chamber can be realized by controlling the starting of the compressor, the starting of the fan and the opening of the refrigerating air door.

Step S104: judging the temperature LC of the refrigerating chamber _c Whether or not it is less than or equal to the refrigerating chamber shutdown point temperature T _coff ；

If the temperature LC of the refrigerating chamber _c Less than or equal to the shutdown point temperature T of the refrigerating chamber _coff The following step S105 is performed, otherwise step S104 is returned.

Step S105: controlling the refrigerating chamber to stop refrigerating;

the controller of the refrigerator controls, for example, the closing of the refrigeration damper such that the freezing duct is not in communication with the refrigeration compartment and no air convection is possible to close the refrigeration of the refrigeration compartment.

Step S106: judging freezing chamber temperature LD _c Whether or not it is less than or equal to the freezing chamber shutdown point temperature T _doff ；

If the temperature LD of the freezing chamber _c Less than or equal to the shutdown point temperature T of the freezing chamber _doff The following step S109 is performed, otherwise the following steps S107 to S108 are performed.

Step S107: judging the temperature LC of the refrigerating chamber _c Whether or not to be greater than or equal to the refrigerating chamber re-opening point temperature T _coff ′；

Wherein, the temperature T of the re-opening point of the refrigerating chamber _coff ' e.g. above the refrigerating compartment shutdown point temperature T _coff And is lower than the starting point temperature T of the refrigerating chamber _con . Exemplary, refrigerator compartment re-open Point temperature T _coff ' specific refrigerator shut offPoint temperature T _coff The temperature was 4℃higher.

If the temperature LC of the refrigerating chamber _c Greater than or equal to the refrigerator compartment re-opening point temperature T _coff ' the following step S109 is performed, otherwise, the process returns to step S106.

Step S108: restarting the refrigerating chamber for refrigerating;

it can be appreciated that, by adding step S107 and step S108, the refrigeration method of the refrigerator provided in the embodiment of the present application can ensure that in the stage of independent refrigeration of the freezing chamber, if the temperature of the refrigerating chamber rises too much due to the reason of door opening, excessively high ring temperature or excessively long independent refrigeration time of the freezing chamber, the refrigerating chamber is restarted for refrigeration, so as to ensure that the temperature of the refrigerating chamber is relatively stable, and can avoid the problem that the compressor cannot be stopped and the power consumption is increased due to excessively high temperature of the refrigerating chamber and restarting refrigeration after the refrigerating chamber is closed for refrigeration.

Step S109: and controlling the freezing chamber to stop refrigerating.

Illustratively, a controller of the refrigerator controls, for example, the compressor, the blower to stop, to stop cooling of the freezer compartment.

According to the refrigerating method of the refrigerator, which is provided by the embodiment of the application, the refrigerating chamber and the freezing chamber can be ensured to be synchronously opened for refrigerating, so that the energy consumption level of the compressor is improved.

The embodiment of the application also provides a refrigerating chamber starting point temperature T _con Temperature T of starting point of freezing chamber _don Temperature T of shutdown point of refrigerating chamber _coff Temperature T of freezing chamber shutdown point _doff The specific calculation formula is as follows:

wherein T is _d1 Is a preset temperature value and is related to the ambient temperature, dh represents a freezer offset parameter.

Wherein T is _d2 Is a preset temperature value and is related to the ambient temperature, d8 represents the freezing chamberThe temperature fluctuation control parameter is, for example, 4.

Wherein T is _c1 Is a preset temperature value and is related to the ambient temperature, ch represents a refrigerating chamber offset parameter.

T _con ＝T _coff +Δh, where Δh is a preset temperature value, e.g., 5.

In the above calculation formula, dh and ch can be performed by a double-eight display panel of the refrigerator, and dh and ch are integers and are adjusted to 0.5 ℃ control precision by dividing by 2. dh. ch can correct the influence caused by the temperature sensing deviation of the ring temperature sensor, and the values of different ring temperature sections are different (refer to the following table I and table II specifically) so as to correct the coincidence of the set gear and the room temperature.

Based on the refrigerating method of the refrigerator, the embodiment of the application also provides a control method of the refrigerator, which can prolong the refrigerating cycle of the refrigerating chamber to be consistent with the refrigerating cycle of the freezing chamber as much as possible so as to improve the energy efficiency level of the refrigerator. Referring to fig. 2, fig. 2 is a first flowchart of a control method of a refrigerator according to an embodiment of the present application. The control method of the refrigerator is performed by, for example, a controller of the refrigerator, and includes the following steps S201 to S204:

step S201: when the temperature of the freezing chamber of the refrigerator is increased to a first preset temperature, controlling a refrigeration air door of the refrigerator to be opened by a first angle, and controlling a compressor of the refrigerator to be started so as to cool the freezing chamber and the refrigeration chamber of the refrigerator;

it should be noted that the first preset temperature is the freezing chamber start point temperature T _don . The first angle is, for example, an initial first angle or a corrected first angle. The controller obtains an initial first angle when receiving a refrigerating air door opening instruction for the first time after the refrigerator is electrified or defrosting is finished, controls the refrigerating air door to be opened according to the initial first angle, and opens a subsequent refrigerating air door according to the corrected first angle. Wherein the initial first angle is a preset value, for example 90 °.

It will be appreciated that the opening angle of the refrigeration damper determines the air flow rate between the refrigeration compartment and the refrigeration duct per unit time, i.e. determines the refrigeration efficiency of the refrigeration compartment. On the premise of a certain frequency of the compressor, the larger the opening angle of the refrigerating air door is, the faster the cooling in the refrigerating chamber is, and the shorter the refrigerating time is; the smaller the opening angle of the refrigerating air door is, the slower the cooling in the refrigerating chamber is, and the longer the refrigerating time is; however, if the opening angle of the refrigeration damper is too small, the temperature in the refrigeration compartment may not drop or even rise reversely. Therefore, by controlling the opening angle of the refrigerating damper, the refrigerating time period of the refrigerating chamber can be controlled.

In the initial state, the compressor of the refrigerator is stopped, the refrigerating air door is closed, and the refrigerating chamber and the freezing chamber are not refrigerated, so that the freezing chamber of the refrigerator can be gradually heated.

Step S202: when the temperature of the refrigerating chamber is reduced to a second preset temperature, the refrigerating air door is controlled to be closed so as to independently refrigerate the freezing chamber;

the second preset temperature isTemperature T of shutdown point of refrigerating chamber _coff . After the refrigerating air door is closed, the refrigerating chamber is separated from the refrigerating air duct of the refrigerator, so that air convection cannot be performed, namely, the refrigerating chamber stops refrigerating.

Step S203: acquiring a first temperature of a freezing chamber when a refrigeration air door is closed;

the first temperature is the actual temperature of the freezer compartment when the refrigeration damper is closed, as measured by a temperature sensor, for example. The first temperature can reflect whether the refrigerating time period of the refrigerating chamber is close to the refrigerating time period of the freezing chamber. If the refrigerating air door is closed, the first temperature in the freezing chamber is close to the temperature of the shutdown point of the freezing chamber, the refrigerating time of the refrigerating chamber is close to the refrigerating time of the freezing chamber, and the energy consumption of the refrigerator is reduced. If the refrigerating air door is closed, the first temperature in the refrigerating chamber is too high, which means that the opening angle of the refrigerating air door is too high, so that the refrigerating capacity of the refrigerating chamber is too high, and the refrigerating time of the refrigerating chamber is shorter; if the first temperature in the refrigerating chamber is too small when the refrigerating air door is closed, the opening angle of the refrigerating air door is too small, and the refrigerating chamber is opened and cooled by a small amount, so that the refrigerating time of the refrigerating chamber is longer. In this case, the temperature of the freezing chamber may already reach the shutdown point, but the compressor is not shutdown because the refrigerating chamber has not reached the shutdown point at the moment, so that the temperature difference between the start and stop of the freezing chamber is actually increased, which is not beneficial to controlling the temperature fluctuation range of the freezing chamber.

Step S204: and correcting and storing the first angle according to the first temperature so that the refrigerating damper is opened next time according to the corrected first angle.

It will be appreciated that the first angle is modified according to the first temperature, and if the first temperature is too high, the first angle is reduced, and if the first temperature is too low, the first angle is increased, so that the refrigerating time of the refrigerating chamber can be controlled to be close to the freezing chamber when the refrigerating air door is opened at the first angle after modification next time, thereby reducing the energy consumption of the refrigerator.

According to the control method of the refrigerator, the opening angle of the refrigeration air door can determine the refrigeration duration of the refrigeration chamber, and the first temperature can reflect whether the freezing chamber is close to the temperature of the shutdown point when the refrigeration air door is closed or not, so that whether the refrigeration duration of the refrigeration chamber is close to the refrigeration duration of the freezing chamber or not is further reflected. Therefore, the first angle is corrected according to the first temperature, so that the cold quantity entering the refrigerating chamber is proper when the next refrigerating air door is opened according to the corrected first angle, and the temperature of the freezing chamber is about to reach the shutdown point when the refrigerating air door is closed, thereby the refrigerating time of the refrigerating chamber is close to the refrigerating time of the freezing chamber, and the energy consumption of the refrigerator is reduced. In addition, according to the control method of the refrigerator, after the refrigerating air door is closed, the temperature of the freezing chamber is close to the shutdown point, the independent refrigerating time of the freezing chamber is shortened, the refrigerating stop time of the refrigerating chamber is shortened, the temperature return degree is reduced, and the control of the temperature fluctuation range of the refrigerating chamber is facilitated.

Further, referring to fig. 3, fig. 3 is a second flowchart of a control method of a refrigerator according to an embodiment of the present application. The control method of the refrigerator includes the following steps S301 to S313:

step S301: judging whether the actual temperature of the refrigerating chamber is increased to a fifth preset temperature;

in the initial state, the refrigerating damper and the compressor are closed, and the refrigerating chamber does not refrigerate, so that the temperature can be gradually increased. The fifth preset temperature is the starting point temperature T of the refrigerating chamber _con . If the actual temperature of the refrigerating compartment reaches the fifth preset temperature, the following step S302 is performed, otherwise the following step S303 is performed.

Step S302: controlling a refrigeration air door of the refrigerator to open a preset maximum angle, and controlling a compressor to start so as to refrigerate a freezing chamber and a refrigerating chamber;

the preset maximum angle is, for example, 90 °. If the refrigerating chamber reaches the starting point temperature, the refrigerator is just electrified, frosted just, or complicated use conditions such as cold storage door opening, high ring temperature and the like exist, and at the moment, in order to obtain enough cold quantity for cooling the refrigerating chamber, the refrigerating air door can be opened according to the maximum opening angle of 90 degrees.

Step S303: judging whether the temperature of the freezing chamber is increased to a first preset temperature or not;

if the temperature of the freezing chamber does not reach the first preset temperature, the process returns to step S301, otherwise, the following step S304 is executed.

Step S304: controlling a refrigeration air door to open a first angle, and controlling a compressor to start;

it should be noted that, the controller monitors the actual temperatures of the refrigerating chamber and the freezing chamber in real time, for example, in step S301 and step S303, which of the refrigerating chamber and the freezing chamber reaches the start point temperature first, if the refrigerating chamber reaches the start point temperature first, the refrigerating damper is controlled to be opened according to the preset maximum angle, and if the freezing chamber reaches the start point temperature first, the refrigerating damper is controlled to be opened according to the first angle.

The freezing chamber reaches the temperature of the starting point first, which means that the refrigerator is in a stable stage in the subsequent normal operation, the refrigerating air door is controlled to be opened at a first angle, and more proper cold energy can be provided for the refrigerating chamber and the freezing chamber, so that the refrigerating time of the refrigerating chamber is fully prolonged, the 1:1 starting and stopping period of the refrigerating chamber and the freezing chamber is realized, and the energy efficiency level of the compressor is improved.

Step S305: judging whether the temperature of the refrigerating chamber is reduced to a second preset temperature;

if the temperature of the refrigerating chamber is reduced to the second preset temperature, the following step S306 is performed, otherwise, the process returns.

Step S306: controlling the refrigeration air door to be closed so as to independently refrigerate the freezing chamber;

step S307: acquiring a first temperature of a freezing chamber when a refrigeration air door is closed;

step S308: judging whether the first temperature is greater than or equal to a third preset temperature;

if the first temperature is greater than or equal to the third preset temperature, the following step S309 is executed, otherwise the following step S310 is executed.

Step S309: reducing the first angle and taking the reduced first angle as a corrected first angle;

the third preset temperature is equal to T _doff +K. It can be understood that the first temperature being greater than or equal to the third preset temperature indicates that the temperature of the freezing chamber exceeds the preset threshold when the refrigeration air door is closed, which indicates that the opening angle of the refrigeration air door is too large in the upper stage, so that the cooling capacity entering the freezing chamber is too small, the refrigerating duration of the refrigeration chamber is shorter, and the air door needs to be reducedOpening angle.

For example, the angle of the difference between the first angle and a pre-stored first preset angle may be determined as the corrected first angle, the first preset angle being for example 5 °.

In other embodiments, referring to fig. 4, fig. 4 is a first flowchart of a method for correcting a first angle provided in the embodiment of the present application, where taking the reduced first angle as the corrected first angle may include the following steps S401 to S403:

step S401: determining a first temperature difference between the first temperature and a third preset temperature;

step S402: calculating a first correction angle according to the first temperature difference value, wherein the first correction angle is in direct proportion to the first temperature difference value;

step S403: the angle of the difference between the first angle and the first corrected angle is used as the corrected first angle.

It can be understood that the larger the temperature difference between the first temperature and the third preset temperature is, the larger the first correction angle is, the larger the amplitude of the first angle is, and the obtained corrected first angle is relatively smaller; conversely, the smaller the temperature difference between the first temperature and the third preset temperature, the smaller the first correction angle, the smaller the amplitude of the first angle, and the obtained corrected first angle is relatively larger. By the correction method of the first angle, the correction amplitude of the first angle is more matched with the first temperature, the correction of the first angle is more intelligent, and the actual requirements are met.

Step S310: judging whether the first temperature is less than or equal to a fourth preset temperature;

if the first temperature is less than or equal to the fourth preset temperature, the following step S311 is performed, otherwise the following step S312 is performed.

Step S311: increasing the first angle and taking the increased first angle as a corrected first angle;

the fourth preset temperature is equal to T _doff . It will be appreciated that a first temperature less than or equal to the fourth predetermined temperature is indicative of a refrigeration damperWhen the temperature of the freezing chamber is lower than a preset threshold value, the fact that the opening angle of the refrigerating air door in the upper stage is too small causes too much cold energy entering the freezing chamber, the refrigerating time of the refrigerating chamber is longer, and the opening angle of the air door needs to be increased.

For example, an angle of a sum of the first angle and a pre-stored second preset angle, for example, 2 °, may be determined as the corrected first angle.

In other embodiments, referring to fig. 5, fig. 5 is a second flowchart of a method for correcting a first angle according to an embodiment of the present application, where taking the increased first angle as the corrected first angle may include the following steps S501-S503:

step S501: determining a second temperature difference between the first temperature and a fourth preset temperature;

step S502: calculating a second correction angle according to the second temperature difference value, wherein the second correction angle is in direct proportion to the second temperature difference value;

step S503: and taking the angle of the sum of the first angle and the second correction angle as the corrected first angle.

It can be understood that the larger the temperature difference between the first temperature and the fourth preset temperature is, the larger the second correction angle is, the larger the amplification of the first angle is, and the obtained corrected first angle is relatively larger; conversely, the smaller the temperature difference between the first temperature and the fourth preset temperature, the smaller the second correction angle, the smaller the increase of the first angle, and the obtained corrected first angle is relatively smaller. According to the correction method of the first angle, the correction amplitude of the first angle can be more matched with the condition of the first temperature, the correction of the first angle is more intelligent, and the actual requirements are met.

Step S312: the first angle maintains the original value;

step S313: and storing the corrected first angle so that the refrigerating damper is opened next time according to the corrected first angle.

It will be appreciated that if the temperature of the freezing chamber is between T when the refrigeration damper is closed _doff To T _doff +KAnd when the refrigerating time length of the refrigerating chamber is basically consistent with the refrigerating time length of the freezing chamber, the first angle is maintained to be the original value.

According to the control method for the refrigerator, when the first temperature is too high, the first angle is corrected to be smaller, when the first temperature is too low, the first angle is corrected to be larger, and therefore the fact that the cold quantity entering the refrigerating chamber when refrigerating next time is suitable is guaranteed, the refrigerating time of the refrigerating chamber is close to the refrigerating time of the freezing chamber, and the energy efficiency level of the refrigerator is improved.
