Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
The fan on the refrigerator has abnormal operation, and fault information needs to be reflected in a refrigerator display terminal or a mobile phone terminal to remind a user or after-sales personnel to carry out targeted maintenance. The fan fault detection mechanism is particularly important, however, the underrigorous fault detection mechanism can cause a certain probability of false alarm faults, namely the current fan is normal, and the display terminal can display fault information.
Accordingly, in order to solve the above problems, the present application proposes a control method of a refrigerator fan and a refrigerator. The present application is further described below with reference to the drawings and embodiments.
Referring to fig. 1, fig. 1 is a flow chart of a control method of a refrigerator fan according to an embodiment of the present application. The embodiment of the application provides a control method of a refrigerator fan, which is applied to a refrigerator, and comprises the following specific flow:
101. and controlling the start of a fan of the refrigerator.
It can be understood that the fan start of the refrigerator can be controlled by starting the fan when the fan start requirement is detected, or simultaneously controlling the fan start when the refrigerator is started, or determining whether the fan start requirement exists according to the state of the stored fan flag bit. The design may be specifically performed according to actual circumstances, and is not particularly limited herein.
It should be noted that in some embodiments, after the fan of the refrigerator is controlled to start, a third preset time is required to be required to forcibly control the fan to operate, and ice residues or ice cubes can be buffered off by forcibly controlling the fan to operate, so that the fan can be started normally when icing or other reasons exist, further the starting capability of the fan in poor environments such as locked-rotor and icing can be improved, the fan can be better in benign operation, the control reliability of the fan is improved, and the accuracy of fan fault detection is also improved.
102. And if the feedback signal of the fan is not obtained within the first preset time, controlling the fan to restart.
The refrigerator includes a first timer for counting time. When the fan starts to start, the first timer starts to count, after the fan is controlled to forcedly execute the third preset time, the controller starts to grab the feedback signal of the fan until the first timer counts the first preset time, and when the first timer counts the first preset time, if the feedback signal of the fan is not acquired, the fan is controlled to restart.
It can be understood that if the feedback signal of the fan is obtained within the first preset time, the fan is indicated to be operating normally, and if the feedback signal of the fan is not obtained within the first preset time, it is necessary to further determine whether the fan is in a fault state.
It should be noted that, the obtaining of the feedback signal of the fan may be that the fan directly sends the feedback signal to the controller, or may be that the controller actively grabs the feedback signal, which is illustrated by taking the feedback signal actively grabbed by the controller as an example, and cannot be understood as limiting the controller, specifically may be set according to the actual situation, and is not limited specifically herein.
The fan is controlled to restart in a circulating start-stop operation mode, and the fan is started for a plurality of times in m seconds, n seconds and then enters a normal operation state after being repeatedly operated for a plurality of times, so that the fan can be ensured to be started smoothly each time. Specifically, after the fan is controlled to run for a fifth preset time, the fan is controlled to stop running, and after the fan is stopped for the sixth preset time, the fan is controlled to be started. The fan is controlled to continuously and circularly start and stop running until the fan is detected to start running.
It should be noted that in some embodiments, after the fan of the refrigerator is restarted, the fan is also required to be forcibly controlled to operate for a fourth preset time, and ice residues or ice cubes can be buffered by forcibly controlling the operation of the fan, so that the fan can be normally started when icing or other reasons exist, further the starting capability of the fan in poor environments such as locked-rotor and icing can be improved, the fan can be better in benign operation, the control reliability of the fan is improved, and the accuracy of fan fault detection is also improved.
The first preset time is determined according to historical data of time for acquiring feedback information after the fan is started or the diameter of fan blades. The first preset time may be determined according to historical data of a time when the fan acquires the feedback information after the fan is started, and the first preset time may be designed by averaging or weighting historical data of a plurality of times.
The first preset time may also be a first preset time determined by determining diameters of fan blades of different fans according to fans of different models, where, by way of example, assuming that the first preset time is a seconds, the diameter of the fan blades is L cm, the fifth preset time is m seconds, and the sixth preset time is n seconds, then the first preset time a=l×m+n.
The third preset time is determined according to the power of the fan, the diameter of the fan blade and the first preset time. For example, assuming that the fan power is P, the unit is W, the first preset time is a seconds, and the diameter of the fan blade is L cm, the third preset time b=p×l×a seconds.
In some embodiments, the fourth preset time is greater than the third preset time, illustratively, twice the third preset time, i.e., the fourth preset time d=2b seconds. The forced execution time after restarting the fan is prolonged, so that the adverse conditions of locked rotor, icing and the like of the fan can be better eliminated, and the accuracy of fan fault detection is further improved.
In some embodiments, on the basis of ensuring the accuracy of the fault detection result, the fourth preset time is set to be equal to or smaller than the third preset time, and the period of the whole fault detection can be shortened by shortening the forced execution time after restarting the fan, so that the effectiveness of the fan detection is improved, and a user can quickly learn the state of the fan.
It should be noted that, in this embodiment, the determination manners of the first preset time, the third preset time and the fourth preset time cannot be understood as the restrictions of the first preset time, the third preset time and the fourth preset time, and specific settings need to be limited according to actual situations, which are not specifically limited herein.
103. If the feedback signal of the fan is not obtained within the second preset time, determining that the fan is in an abnormal working state.
When the fan is forced to execute the fourth preset time, the first timer starts to count, and the controller starts to grab the feedback signal of the fan until the first timer counts to the second preset time, and then grabbing is stopped. And in the second preset time counted by the first timer, if the feedback signal of the fan is not acquired, determining that the fan is in an abnormal working state.
It should be noted that, in some embodiments, the second preset time is greater than the first preset time, and illustratively, the second preset time is twice the first preset time, that is, the second preset time c=2a. The time for obtaining the feedback of the fan after restarting the fan is prolonged, so that the situation that the fan does not send feedback information due to the fact that the fan is in a bad state such as locked rotor and icing can be better avoided, and the accuracy of fan fault detection is further improved.
In some embodiments, on the basis of ensuring the accuracy of the fault detection result, the second preset time is set to be equal to or less than the first preset time, and the period of the whole fault detection can be shortened by shortening the time for obtaining the feedback of the fan after restarting the fan, so that the effectiveness of the fan detection is improved, and a user can quickly know the state of the fan.
The control method also requires that fault information be communicated to the user after determining that the fan is in an abnormal operating state. In some embodiments, the refrigerator includes a display terminal, and after determining that the fan is in an abnormal operation state, the refrigerator transmits a fault signal to the display terminal and controls the display terminal to display fault information according to the fault signal. In other embodiments, the refrigerator comprises a wifi module, after the fan is determined to be in an abnormal working state, fault information is sent to the cloud or external equipment by the wifi module, and whether the refrigerator fan is in an abnormal state or not can be accurately prompted to a user and after-sales personnel.
Referring specifically to fig. 2, fig. 2 is a schematic flow chart of processing a feedback signal in the control method shown in fig. 1. The method comprises the following specific steps:
201. if the feedback signal of the fan is obtained, the fan is confirmed to be in a normal working state.
If the feedback signal of the fan is obtained in the first preset time or the second preset time, the fan is confirmed to be in a normal working state.
When the fan is confirmed to be in normal operation, the fan can be controlled to start and stop circularly for a preset number of times, and then the fan is controlled to operate at a preset maximum rotation speed. And after the fan is controlled to operate for a preset time period at a preset maximum rotating speed, controlling the fan to operate according to a preset operation program. Through running the fan at the maximum rotational speed of predetermineeing for a predetermined time, can throw away the moisture on the fan, prevent freezing after the refrigerator is refrigerated, control fan at the maximum rotational speed operation after waiting for the settlement duration, try to improve the operational reliability of refrigerator. The specific values of the preset times and the set time period are not unique, and can be specifically set according to actual application conditions, and are not specifically limited herein.
202. And sending the non-fault information to the display terminal, and controlling the display terminal to clear the fault information according to the non-fault information.
It can be appreciated that the display terminal may display fault information, for example, when the flag bit of the fan is 1, the fan may be considered to be in a fault state; when the fan flag bit is 0, the fan can be considered to be in a non-fault state. The fan can be known whether to be in a fault state or not by a simple sign, so that the fan can be conveniently connected by a user, and the use safety of the refrigerator is improved.
And after confirming that the fan works normally, sending the non-fault information to the display terminal, and controlling the display terminal to clear the fault information according to the non-fault information so as to enable the fan flag bit to be 0.
It can be appreciated that, in some embodiments, in order to more accurately determine whether the fan of the refrigerator is in a fault state, the duration of acquiring the feedback information of the fan may be appropriately prolonged, and may specifically be set according to the actual situation, which is not limited herein. In other embodiments, in order to more accurately determine whether the fan of the refrigerator is in a fault state, after the feedback signal of the fan is not obtained in the second preset time, the fan may be restarted for multiple times, and then the feedback information of the fan is obtained, so that after the preset times of circulation, if the feedback information of the fan is not obtained, the fan is determined to be in the fault state. The preset number of times is set according to the actual situation, and is not particularly limited here.
