And after the corresponding operation time length is found in the preset mapping table, installing the operation time length, controlling the fan 3 to be started and operated, and controlling the fan 3 to stop operating when the fan 3 operates to the operation time length. For example, as shown in Table 1, when the outdoor environment temperature TOGreater than 35 ℃ and outdoor environment humidity HOMore than 80 percent, and the door opening time of the refrigerator is more than or equal to t within 1min1When the time is less than or equal to 6min, the operation time t of the fan 3 is found in the preset mapping table2And 9min, controlling the fan 3 to be started and operated. In this embodiment, in the process of fan 3 operation, be located the air inlet of a plurality of air duct 20 on fan 3 left side, be located the air-out of a plurality of air duct 20 on fan 3 right side to form the adherence air current in freezing drawer 100, realize freezing drawer 100's automatic defrosting process. And when the operation of the fan 3 reaches 9min, controlling the fan 3 to stop operating, and finishing defrosting.
In this embodiment, it is long through the door that obtains outdoor ambient temperature, outdoor ambient humidity and refrigerator, and obtain with outdoor ambient temperature outdoor ambient humidity and it is corresponding to open the door time length the operation of fan 3 is long, again according to long, control of operation the operation of fan 3 can realize freezing drawer 100's automatic defrosting process, need not manual defrosting, improves user's use experience, and, according to outdoor ambient temperature, outdoor ambient humidity and refrigerator open the door and long the operation of confirming fan 3 is long, can improve the validity and the accuracy of defrosting, make fan 3 move reasonable length of time back stall, reduce the energy consumption.
Further, as shown in fig. 8, fig. 8 is a schematic flowchart of a defrosting method for a freezer drawer 100 according to a second embodiment of the present invention, and based on the first embodiment, before step S20, the method further includes:
s11, detecting that the storage box is in a humidifying state, and acquiring the humidifying frequency of the storage box;
specifically, in the process of detecting that the freezer drawer 100 is in a humidified state and acquiring the humidification frequency of the freezer drawer 100, it is first determined whether the freezer drawer 100 is in a humidified state. In the refrigerator of this embodiment, cold-stored return air inlet passes through a return air pipe and freezes drawer 100 intercommunication, is provided with the fan in the return air pipe to pass through the return air pipe blowback with the high humid air of walk-in to freezing drawer 100, realize the high humid effect in freezing drawer 100. The main control board can judge whether the freezing drawer 100 is in a humidifying state according to whether the fan in the return air pipe is in an operating state, namely, if the fan in the return air pipe operates, the freezing drawer 100 is judged to be in the humidifying state, and if the fan in the return air pipe does not operate, the freezing drawer 100 is judged to be in a non-humidifying state. When it is judged that the freezer drawer 100 is in the humidifying state, the humidifying frequency of the freezer drawer 100 is acquired, and it can be understood that the humidifying frequency of the freezer drawer 100 can be acquired according to the operation state of the fan in the return duct.
Step S20 includes:
step S201, obtaining the operation time of the fan 3 corresponding to the outdoor environment temperature, the outdoor environment humidity, the door opening time and the humidification frequency.
In this embodiment, the preset mapping table further includes a humidification frequency in addition to the outdoor environment temperature, the outdoor environment humidity, and the door opening time. When the refrigeration drawer 100 is judged to be in the humidification state, the corresponding operation time length of the fan 3 is searched in a preset mapping table according to the outdoor environment temperature, the outdoor environment humidity, the door opening time length and the humidification frequency. And controlling the fan 3 to start and operate, and controlling the fan 3 to stop operating when the operating time is reached. The embodiment also judges the humidification state of the freezing drawer 100 on the basis of the first embodiment, obtains the humidification frequency of the freezing drawer 100 when the freezing drawer 100 is in the humidification state, and takes the humidification frequency as a search condition when searching the operation duration of the fan 3 in a preset mapping table, thereby further improving the effectiveness and accuracy of defrosting. It can be understood that, when the humidification frequency is 0, the freezer drawer 100 is in a moisture-preserving state, and the defrosting can be performed according to the defrosting method of the freezer drawer 100 in the first embodiment; when the humidification frequency is not 0 and the humidification frequency is higher, the operation time period of the fan 3 is longer.
Further, as shown in fig. 9, fig. 9 is a schematic flowchart of a defrosting method for a freezer drawer 100 according to a third embodiment of the present invention, and based on the first embodiment, step S10 includes:
step S101: acquiring outdoor environment temperature, outdoor environment humidity, door opening time of refrigeration equipment and the number of the fans 3;
step S202: and acquiring the running time of the fan 3 corresponding to the outdoor environment temperature, the outdoor environment humidity, the door opening time and the number of the fans 3.
In this embodiment, the number of the fans 3 may be one or multiple, and when the number of the fans 3 is multiple, the multiple fans 3 are arranged in the air duct 2 at intervals. On the basis of the first embodiment, the number of the fans 3 is also added as a search condition, that is, the number of the fans 3 is also used as a search condition when the fans 3 in the preset mapping table are searched for operating for a long time, so that the effectiveness and the accuracy of defrosting are further improved, and the energy consumption is reduced. It can be understood that, when the number of the fans 3 is plural, the operation time of the fan 3 is shorter than that when the number of the fans 3 is one, for example, when the outdoor environment temperature, the outdoor environment humidity and the door opening time of the refrigerator are the same, when the number of the fans 3 is one, the operation time of the fan 3 is 10min, and when the number of the fans 3 is two, the operation time of the fan 3 is 5 min.
It should be noted that, in other embodiments, at least three of the outdoor environment temperature, the outdoor environment humidity, the door opening duration of the refrigerator, the humidification frequency of the freezing drawer 100, and the number of the fans 3 may be used as conditions for looking up the operation duration of the fans 3 in the preset mapping table, so that the refrigerator may control the operation of the fans 3 according to the outdoor environment temperature, the outdoor environment humidity, the door opening duration of the refrigerator, the humidification frequency of the freezing drawer 100, the number of the fans 3, and other factors, so as to implement the automatic defrosting process of the freezing drawer 100, improve the effectiveness and accuracy of defrosting, and reduce energy consumption.
