Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
For example, a method for repairing a refrigerator damper includes the steps of: judging whether the temperature of the refrigerating chamber is abnormal or not; when the temperature of the refrigerating chamber is abnormal, executing an air door resetting action to stop the air door under a closing instruction; and heating the air door, and stopping heating after a first preset time.
To further illustrate the control method of the control panel, please refer to fig. 1, which is a schematic flow chart illustrating a method for repairing a failure of a damper of a refrigerator according to an embodiment of the present invention, wherein the method for repairing a failure is suitable for a refrigerator, for example, an air-cooled refrigerator, for example, a single-system air-cooled refrigerator. For example, the refrigerator comprises a refrigerating chamber and a freezing chamber, the air door is arranged between the freezing chamber and the refrigerating chamber, and the air door is used for controlling the refrigerating chamber to refrigerate the refrigerating chamber when the refrigerator operates in a refrigerating mode. Specifically, when the refrigeration mode is operated, the freezing chamber is refrigerated through the evaporator, and if the refrigerating chamber needs to be refrigerated, the refrigerating air generated by the freezing chamber enters the refrigerating chamber to be refrigerated by controlling the opening of the air door. As shown in fig. 1, the illustrated fault repair method includes the steps of:
s101, judging whether the temperature of the refrigerating chamber is abnormal or not.
For example, before determining whether the temperature of the refrigerating chamber is abnormal in step S101, the method further includes collecting the temperature of the refrigerating chamber. The temperature of the refrigerated compartment is collected, for example, by a refrigerated sensor. For example, the temperature of the refrigerating chamber is periodically collected by a refrigerating sensor according to a certain frequency so as to monitor whether the temperature of the refrigerating chamber is abnormal or not in real time. The frequency of acquisition may be set based on empirical values. For example, in order to accurately monitor whether the temperature of the refrigerating chamber is abnormal in real time, a high collection frequency is set, such as several times per second. As another example, in order to reduce power consumption and data processing amount, a lower acquisition frequency is set, such as one acquisition for several seconds.
Generally, a temperature anomaly includes both above a set point and below a set point. On one hand, if the air door is frozen before being opened, the air door cannot be opened subsequently, the refrigerating chamber cannot be refrigerated, and the temperature of the refrigerating chamber is overhigh in the long-term use process; on the other hand, if the air door is frozen before being closed, the air door cannot be closed subsequently, and cold air generated by refrigerating of the freezing chamber is blown to the refrigerating chamber when the refrigerating chamber does not need to refrigerate, so that the temperature of the refrigerating chamber is too low. Therefore, the temperature of the refrigerating chamber is excessively high or low, which is a case of abnormal temperature of the refrigerating chamber.
For example, determining whether the temperature of the refrigeration compartment is abnormal includes determining whether the temperature of the refrigeration compartment deviates from a set value by more than a positive or negative first preset temperature. Specifically, the judging whether the temperature of the refrigerating chamber is abnormal includes judging whether the temperature of the refrigerating chamber exceeds a set value and a first preset temperature or is lower than the set value and the first preset temperature. For example, the first predetermined temperature is 3 to 5 ℃. For example, the first preset temperature is 4 ℃.
And S102, when the temperature of the refrigerating chamber is abnormal, executing a damper resetting action to stop the damper under a closing command.
Because the air door does not have signal feedback device, in case the air door trouble is because of can't judge that the air door can't close or can't open to can't judge the position that the air door actually was located, consequently, carry out this correction procedure of air door reset action, can guarantee that the air door is in a controllable position, regard as the prosthetic benchmark of later stage air door with this, make the air door move in controllable scope.
S103, heating the air door, and stopping heating after a first preset time.
For example, the damper is heated by a damper heating wire and the heating is stopped after a first preset time period. For example, damper heater wires are provided around the damper for preventing the damper from freezing. For example, in order to reduce power consumption, the power of the damper heating wire is 1-3W.
For example, the first preset time period is 8 to 12 minutes. For example, the first preset time period is 10 minutes. The air door is heated for a long time by the air door heating wire, so that the thorough repair of the air door is further ensured.
According to the fault repairing method, when the temperature of the refrigerating chamber is abnormal, the air door is forcibly heated in real time, so that the problem of refrigeration abnormality of the refrigerating chamber caused by freezing of the air door knot is timely repaired, and large energy consumption waste in the normal operation process is avoided.
To further determine whether the damper repair was successful. For example, referring to fig. 2, after step S103, namely after the damper is heated and the heating is stopped after a first preset time period, the fault repairing method further includes the steps of:
and S105, operating the refrigeration mode, and closing after operating for a second preset time.
For example, after the cooling mode is operated, if the damper is restored under the cooling demand of the temperature of the refrigerating chamber, the damper is opened or closed according to the cooling demand of the refrigerating chamber, so that the temperature of the refrigerating chamber is restored to normal. If the air door is not repaired, the refrigerating chamber still cannot be normally cooled by controlling the opening and closing of the air door.
For example, the second preset time period is 8 to 12 minutes. For example, the second preset time period is 10 minutes. By setting the operation time of the refrigeration mode to be long enough, the requirement that the normal temperature of the refrigerating chamber is recovered is fully guaranteed.
S107, collecting the temperature of the refrigerating chamber.
The temperature of the refrigerated compartment is collected, for example, by a refrigerated sensor. For example, the temperature of the refrigerating chamber is periodically collected by a refrigerating sensor according to a certain frequency so as to monitor whether the temperature of the refrigerating chamber is abnormal or not in real time. The frequency of acquisition may be set based on empirical values. For example, in order to accurately monitor whether the temperature of the refrigerating chamber is abnormal in real time, a high collection frequency is set, such as several times per second. As another example, in order to reduce power consumption and data processing amount, a lower acquisition frequency is set, such as one acquisition for several seconds.
And S109, continuously judging whether the temperature of the refrigerating chamber is abnormal or not.
If the air door is repaired, the opening and closing of the air door can be controlled according to the refrigeration requirement of the refrigerating chamber, and the temperature of the refrigerating chamber is recovered to be normal after the refrigerating mode runs for a second preset time.
If the air door is not repaired, the opening and closing of the air door still cannot be controlled according to the refrigeration requirement of the refrigerating chamber, and the temperature of the refrigerating chamber still is abnormal and cannot be recovered to be normal. For example, when it is determined that the temperature of the refrigerating compartment is abnormal, the steps S102 and S103 are repeated. After the temperature of the refrigerating chamber is judged to be abnormal continuously, when the temperature of the refrigerating chamber is abnormal, the air door is reset, and the air door is stopped under a closing instruction; and heating the air door, and stopping heating after a first preset time.
In the steps S105 to S109, after the damper is repaired, the temperature of the refrigerating chamber is detected by operating the refrigeration mode for the second preset time period to make the temperature of the refrigerating chamber approach to normal, and whether the damper is repaired is determined by determining whether the temperature of the refrigerating chamber is restored to normal, and if the damper is not repaired successfully, the steps S102 and S103 may be repeated to repair the damper again.
In order to limit the number of repeated repairs to the damper and to more effectively perform further repairs to the damper, for example, the refrigerator further includes a defrosting device, for example, a defrosting heater wire. After step S103 and before step S105, namely before the heating of the damper is performed and the heating is stopped after the first preset time period, and before the cooling mode is operated, the fault repairing method further includes:
and S104, judging whether the air door resetting action executed within the third preset time does not exceed the preset times, if so, operating the refrigeration mode, otherwise, defrosting, and stopping defrosting after the fourth preset time.
For example, the predetermined number of times is 2 to 4 times. For example, the preset number of times is 3. In this embodiment, if the damper is not repaired after the damper is repaired 3 times by repeating the steps S102 and S103, the method is abandoned, and a more effective method is needed to repair the damper to avoid doing useless work.
For example, defrosting is performed by a defrosting heater wire. For example, the power of the defrosting heating wire is 200W. After the air door heater strip operates certain number of times, still can't restore the air door, adopt the great powerful frost heater strip that changes, calorific capacity is great, and is more effective to the defrosting of air door, nevertheless because change the setting of frost heater strip at the freezer, its during operation also can influence the freezer temperature, consequently only after the air door heater strip operates certain number of times, just select the mode that adopts the defrosting of change frost heater strip to defrost the air door.
In order to detect whether the temperature abnormality of the refrigerating compartment is caused by a door opening event, for example, referring to fig. 3, before the damper resetting operation is performed when the temperature of the refrigerating compartment is abnormal, the fault repairing method further includes:
and S111, detecting whether a door opening event occurs.
When the temperature of the refrigerating chamber is abnormal, the temperature is not necessarily caused by the fault of the air door, when the door is opened, the temperature of the refrigerating chamber is increased because hot air with higher external temperature rushes into the refrigerator, and the abnormal temperature can be displayed by detecting the temperature of the refrigerating chamber at the moment. Therefore, whether the door opening event exists or not can be detected, the abnormal temperature condition of the refrigerating chamber caused by the door opening event can be eliminated, the air door is prevented from being repaired when the air door is not frozen and frozen, and the power consumption of the refrigerator is increased.
S113, if the door opening event is detected and the distance between the detection time point and the occurrence time point of the door opening event does not exceed a fifth preset time, continuously judging whether the temperature of the refrigerating chamber is abnormal or not after the fifth preset time is exceeded.
In this embodiment, if the door opening event is detected, but the time is not short enough from the occurrence time of the door opening event, the abnormal temperature of the refrigerating chamber caused by the door opening event cannot be eliminated, so it is necessary to continuously determine whether the temperature of the refrigerating chamber is abnormal after the time is long enough from the occurrence time of the door opening event to determine whether the temperature of the refrigerating chamber is abnormal due to the door opening event or the temperature of the refrigerating chamber is abnormal due to freezing and freezing of the air door.
For example, the fifth preset time period is 0.8 to 1.2 hours. For example, the fifth preset time period is 1 hour. The influence of the door opening event on the temperature of the refrigerating chamber can be eliminated by setting whether the temperature of the refrigerating chamber is abnormal after the door opening event occurs for a long enough time.
S115, if the door opening event is detected, the distance between the detection time point and the occurrence time point of the door opening event exceeds a fifth preset time, or the door opening event is not detected, continuing to execute the air door resetting action.
In this embodiment, if a door opening event is detected but the door opening event is generated for a long time, the temperature abnormality of the refrigerating compartment, which may be caused by the door opening event, is excluded. If the door opening event is not detected, the condition that the temperature of the refrigerating chamber is abnormal due to the door opening event is eliminated. Thus, it is determined that the temperature of the refrigerating chamber is abnormal due to freezing and freezing of the damper.
For example, if the door opening event is detected and the detection time point is more than a fifth preset time length from the occurrence time point of the door opening event, or the door opening event is not detected, the steps of S102 and S103 are repeated. When the temperature of the refrigerating chamber is abnormal, if the door opening event is detected and the distance between the detection time point and the occurrence time point of the door opening event exceeds a fifth preset time length, or the door opening event is not detected, executing an air door reset action to stop the air door under a closing instruction; and heating the air door, and stopping heating after a first preset time.
In the steps S111 to S115, when the temperature of the refrigerating chamber is detected to be abnormal, the influence of the door opening event on the temperature of the refrigerating chamber is eliminated, so that the air door is prevented from being repaired when the air door is normal, the energy consumption is increased, and the capability of correctly judging the abnormality of the air door is improved.
In order to detect whether the temperature abnormality of the refrigerating compartment is caused by a failure of the refrigerating system of the refrigerator, for example, referring to fig. 4, after the door opening event is detected and the detection time point is more than a fifth preset time period from the occurrence time point of the door opening event, or the door opening event is not detected, before continuing to perform the damper resetting operation, the failure repairing method further includes:
and S117, collecting the temperature of the freezing chamber.
The temperature of the freezer compartment is collected, for example, by a freeze sensor. For example, the temperature of the freezing chamber is periodically collected by a freezing sensor according to a certain frequency so as to monitor whether the temperature of the freezing chamber is abnormal or not in real time. The frequency of acquisition may be set based on empirical values. For example, in order to accurately monitor whether the temperature of the freezing chamber is abnormal in real time, a high collection frequency, such as several times per second, is set. As another example, in order to reduce power consumption and data processing amount, a lower acquisition frequency is set, such as one acquisition for several seconds.
S118, judging whether the temperature of the freezing chamber is abnormal or not;
s119, defrosting is carried out if the time is up, and defrosting is stopped after a sixth preset time;
and S120, if not, continuing to execute the damper resetting action.
In the steps S117 to S120, after the abnormal temperature of the refrigerating chamber caused by the door opening event is eliminated, the abnormal condition of the refrigerating chamber caused by the failure of the refrigeration system of the refrigerator is eliminated by judging whether the temperature of the freezing chamber is abnormal or not and defrosting when the temperature of the freezing chamber is abnormal, so as to avoid the repairing of the air door when the air door is not failed and increase the power consumption.
In order to provide a feedback warning when the refrigeration system of the refrigerator is in failure, the refrigerator further comprises an alarm, for example, the alarm is a buzzer. Referring to fig. 5, for example, after defrosting is stopped, the fault repairing method further includes:
s210, collecting the temperature of the refrigerating chamber;
s212, when the temperature of the refrigerating chamber is abnormal, the alarm is started.
For example, the alarm is an audible alarm, and a buzzer manner is adopted to remind a user of abnormal refrigeration of the refrigerator. For example, the alarm is an audible and visual alarm, and reminds a user of abnormal refrigeration of the refrigerator through alarm prompt tones and flashing lamps.
In the steps S210 to S212, after the damper repairing action is performed, and the refrigeration cannot be recovered to normal through defrosting, the refrigerator refrigeration system fails, and the user can be timely reminded by starting the alarm.
According to the fault repairing method, whether the air door is in fault or not can be judged by collecting whether the temperature of the refrigerating chamber and/or the freezing chamber is abnormal or not and whether a door opening event occurs or not, the air door is effectively repaired by heating the air door firstly, the air door is repaired in a forced defrosting mode under the condition that the heating and repairing of the air door are invalid, and when the air door cannot be repaired by a series of repairing means, the refrigerator refrigeration abnormality is reminded through an alarm, so that a method for automatically detecting and repairing the air door in real time is provided, and the refrigerator refrigeration abnormality can be monitored at the same time.
