And obtaining the updated historical door opening and closing data.
Further, step S11 executed by the control device 15, that is, when the door opening signal of the refrigerator door sent by the door opening and closing detection device is received, the average door opening duration of the refrigerator is obtained, specifically:
s111, when a door opening signal of the refrigerator door sent by the door opening and closing detection device is received, identity identification information of the refrigerator is uploaded to the cloud server, so that the cloud server returns the average door opening duration corresponding to the identity identification information according to the identity identification information;
and S112, acquiring the average door opening time of the refrigerator returned by the cloud server.
In a preferred embodiment, the cloud server is further configured to execute preprocessing for removing abnormal data before updating the historical door opening and closing data.
Specifically, the cloud server calculates the door opening duration of the current turn according to the corresponding time of the door opening signal and the door closing signal, and then rejects the door opening duration with too short time (for example, less than 20s), and rejects the door opening duration with too long time. And if the door opening duration of the current turn is eliminated, the corresponding door opening times are not subjected to plus one processing.
By adopting the technical means of the embodiment of the invention, the statistics and updating of the historical door opening and closing data of the refrigerator and the calculation of the average door opening time are realized through the cloud server, the larger data processing can be carried out, the data processing amount of the refrigerator is reduced, the dynamic adjustment of the door opening alarm time of the refrigerator is realized through the interaction of the refrigerator and the cloud server, and the use experience of a user is effectively improved.

The historical door opening and closing data comprises the door opening duration t of each turn of the refrigerator counted before the current momentnThe date type and the door opening times n corresponding to the door opening time length.
Specifically, each time the refrigerator opens the door, the door opening and closing detection device 13 generates a door opening signal and sends the door opening signal to the control device 15, and the control device 15 records the time corresponding to the door opening signal and obtains the date type of the day; next, when the refrigerator is closed, the door opening and closing detection device 13 generates a door closing signal and transmits the door closing signal to the control device 15, and the control device 15 records a time corresponding to the door closing signal. The control device 15 calculates the door opening duration t of the current turn according to the corresponding time of the door opening signal and the door closing signaln。
The control device 15 calculates the door opening time t of the current turnnCorresponding date classAnd binding and storing the type in an internal memory, adding one to the stored door opening times n, and obtaining the updated historical door opening and closing data according to the newly stored door opening time t, the corresponding date type and the updated door opening times n.
In step S22, the control device 15 obtains the historical door opening and closing data corresponding to the current date type from the current date type and the stored historical door opening and closing data, and calculates an average door opening time of the refrigerator.
Further, according to the average door opening duration of the refrigerator, the current door opening alarm duration of the refrigerator is calculated, the door opening alarm timing is started, and whether a door closing signal of the refrigerator door sent by the door opening and closing detection device 13 is received or not is detected in the process that the timing reaches the door opening alarm duration T. If yes, the refrigerator door 12 is closed, and no alarm reminding is needed. If the door opening alarm duration T elapses, the door closing signal of the refrigerator door sent by the door opening and closing detection device 13 is not received yet, indicating that the refrigerator door 12 has been opened for a long time, and therefore, the control device 15 controls the alarm device 14 to send alarm information to remind the user of closing the door in time.
It can be understood that, in the embodiment of the present invention, the storage of the historical door opening and closing data of the refrigerator and the calculation of the average door opening duration of the refrigerator can also be performed by the cloud server, and specific reference may be made to the above related embodiments, which are not described herein again.
Preferably, the date types include: a weekday date type and a non-weekday date type.
Under the normal condition, the using time of the refrigerator by a user on a working day is shorter, the refrigerator is more frequently used on a non-working day, and the door opening time is longer each time, so that the door opening alarming time is set according to the historical door opening and closing data of the working day and the non-working day by distinguishing the types of the working day and the non-working day, and the using requirements of the user are better met.
It should be noted that the date type may also be defined according to the usage habit and the requirement of the user, for example, if a single number of each month is set as a first date type, and a double number of each month is set as a second date type, the control device 15 or the cloud server may perform statistics and storage on historical door opening and closing data corresponding to different date types according to the date type set by the user, which does not affect the beneficial effect obtained by the present invention.
By adopting the technical means of the embodiment of the invention, the difference of the door opening times and the door opening duration of the refrigerator under different date types can be effectively considered, the door opening alarm duration of the refrigerator after each door opening is calculated in real time according to the historical door opening and closing data corresponding to the date type when the user opens the door, so that the door opening alarm duration of the refrigerator can be dynamically adjusted according to the use habit of the user on the refrigerator, and compared with the method that the door opening alarm duration of the refrigerator is set as a fixed value, the embodiment of the invention can effectively reduce the condition that the alarm is triggered in the process of using the refrigerator by the user, can also effectively reduce the condition that the cold quantity of the refrigerator is greatly lost because the user is not reminded to close the door for too long time, and improves the use experience of the user.
Referring to fig. 3, a schematic structural diagram of a preferred refrigerator according to an embodiment of the present invention is shown as a preferred embodiment. On the basis of any of the above embodiments, the refrigerator 10 further includes: and the human body sensing device 16 is arranged on the refrigerator body 11 and used for detecting whether personnel activities exist in the area with the preset distance away from the refrigerator body.
Then, before step S13 or step S24, that is, before the door opening alarm timer is started, the control device is further configured to execute step S31:
s31, judging whether personnel activities exist in the area which is away from the refrigerator body by a preset distance;
if no human activity exists, go to step S13 or step S24: starting door opening alarm timing;
