Description

Refrigerator fault operation method
Technical Field
The invention belongs to the technical field of refrigerator fault detection, and particularly relates to a refrigerator fault operation method.
Background
During the use process of the refrigerator, the compressor can be continuously operated and closed, and each time the compressor is operated and closed, the operation and the closing of the compressor are called a refrigerating cycle. When the compressor is in operation, the temperature of the evaporator is reduced, and for a refrigerator with a single system, the freezing temperature begins to be reduced during the operation of the compressor, and when the temperature of the refrigerating chamber is increased to reach a starting point, the refrigerating air door is opened, and cold air enters the refrigerating chamber to reduce the temperature; when the refrigerating temperature is reduced to a certain temperature, the refrigerating air door is closed, and the temperature stops to be reduced. In addition, in order to prevent excessive frosting on the evaporator and influence the refrigerating efficiency of the refrigerator, the refrigerator enters a defrosting mode after refrigerating for a period of time, and in the defrosting mode, the heater heats according to the frosting quantity of the evaporator, and the frosting quantity is heated for different time.
The refrigerator sometimes has sensor faults, such as refrigerator sensor faults, freezing chamber sensor faults, defrosting sensor faults, ambient temperature sensor faults and the like, in the actual use process. When the sensor fails, the refrigerator cannot perform normal refrigeration control due to the fact that accurate temperature feedback is not available. The current control mode is generally that when any sensor at the refrigerator end fails, the refrigerator enters a fixed failure operation mode. In this failure mode of operation, the refrigerator typically cools the fresh food compartment for a predetermined period of time during freezing, and then shuts down for a predetermined period of time, thus cyclically cooling.
The current failure mode of operation is too mechanical to take into account that the remaining sensors may still be used properly when an individual sensor fails. In addition, the use habit of different users is not considered, the environment temperature is different in different seasons, and the refrigerating time required by the refrigerator is also different. If the same refrigeration mode is adopted, the temperature control of the refrigerator can deviate a lot from the normal condition for different users in different seasons, and finally, the temperature in the refrigerator is too high, so that the food is quickly spoiled.

And after receiving the command, the refrigerator end carries out refrigeration control on the refrigerating chamber according to the control time sent by the cloud, and the freezing chamber is controlled according to the temperature value of the freezing chamber temperature sensor.
The cloud computing method for the average refrigerating time tc1 of the refrigerating chamber is as follows:

(4) the refrigeration average non-refrigeration time tnc1 is obtained by dividing the refrigeration accumulated non-refrigeration time by the refrigeration cycle N.
When the cloud detects that the freezing sensor of the refrigerator fails, historical data of time t1 before the refrigerator fails are calculated to obtain average refrigerating time td1 of the freezing chamber and average non-refrigerating time tnd1. After the calculation is finished, the cloud end sends a command to the refrigerator, informs the refrigerator of entering a fault operation mode of the freezing sensor, and sends average refrigerating time td1 and average non-refrigerating time tnd1 of the freezing chamber to the refrigerator end. And after receiving the command, the refrigerator end carries out refrigeration control on the freezing chamber according to the control time sent by the cloud, and the refrigerating chamber is controlled according to the temperature value of the refrigerating chamber temperature sensor.

(1) counting accumulated heating time tz0 of defrosting heaters in the first N defrosting modes;
(2) dividing the accumulated heating time tz0 of the defrosting heater by N gives the average heating time tz1 of the defrosting heater.
When the cloud detects that an ambient temperature sensor of the refrigerator fails, the cloud obtains the position of the failed refrigerator according to a wifi module on the failed refrigerator, obtains temperature data of the area where the failed refrigerator is located according to network weather data according to the position, and sends the temperature data to the refrigerator for use;
after the refrigerator enters a defrosting mode, a sectional heating mode is adopted, and the switching temperature points of defrosting heaters in different defrosting stages are different.
