Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0028] like Figure 1 As shown, in the first aspect, an embodiment of the present application provides a refrigerator control method, which includes S10~S30, and can better take into account the normal startup of refrigeration and the factory inspection process, ensuring that the refrigerator 1 can quickly complete the power-off restart and factory inspection process.

[0029] The refrigerator 1 is provided with a compressor, a freezing chamber and a defrosting sensor. The type of the compressor can be determined according to actual needs, and the embodiment of the present application does not limit this; for example, the compressor can be a fixed-frequency compressor, and accordingly, the refrigerator 1 can be a fixed-frequency refrigerator. The freezing chamber is used to store frozen food to extend the storage time of the food. The defrosting sensor is arranged in the freezing chamber to detect the actual temperature in the freezing chamber.

[0030] S10: In response to the refrigerator 1 being powered on, determining whether the temperature measured by the defrost sensor is lower than a preset freezing temperature.

[0031] Here, the preset freezing temperature can be pre-set in the control system of the refrigerator 1 and can be used as the upper limit of the freezing temperature of the freezing chamber; when the refrigerator 1 is running for refrigeration, the temperature of the freezing chamber is maintained below the preset freezing temperature to ensure the freezing and preservation effect of the freezing chamber. The value of the preset freezing temperature can be determined according to actual needs, and the embodiment of the present application does not limit this; for example, the preset freezing temperature can be set to -18°C.

[0032] After the refrigerator 1 is powered on, the temperature measured by the defrost sensor is first obtained, and the temperature measured by the defrost sensor is compared with the preset freezing temperature to determine the deviation between the actual temperature in the freezing chamber and the preset freezing temperature.

[0033] S20: In response to determining that the temperature measured by the defrost sensor is lower than the preset freezing temperature, controlling the compressor to start with a delayed start.

[0034] When it is determined that the temperature measured by the defrost sensor is lower than the preset freezing temperature, it can be determined that the actual temperature of the freezer is lower than the preset freezing temperature, and further it can be determined that the time interval between the last power-off time and the current time of the refrigerator 1 is short, which belongs to the situation where the refrigerator 1 is powered on and started immediately after the power is off. At this time, the compressor can be controlled to start with a delay, that is, the compressor can be controlled to continue to remain in a stopped state until the pressure difference of the compressor is completely eliminated or reduced to a safe range before the compressor is controlled to start, so as to avoid the compressor from being started when the pressure difference is large and suffering structural damage, and ensure the safety and reliability of the refrigerator 1 when starting.

[0035] S30: In response to determining that the temperature measured by the defrost sensor is greater than or equal to the preset freezing temperature, controlling the compressor to start immediately.

[0036] When it is determined that the temperature measured by the defrost sensor is greater than or equal to the preset freezing temperature, it can be determined that the actual temperature of the freezer is above the preset freezing temperature, and then it can be determined that the time interval between the last power-off time and the current time of the refrigerator 1 is long, or the refrigerator 1 has not been powered on before the current time, and it belongs to the situation that the refrigerator 1 is powered on after a long power-off period, or the refrigerator 1 is powered on for the first time. At this time, the compressor can be controlled to start immediately, so that the refrigerator 1 can quickly start normal refrigeration or enter the factory inspection process, and then quickly respond to the user's refrigeration use needs or factory inspection needs.

[0037] Compared with the related art, the refrigerator control method provided in the embodiment of the present application compares the temperature measured by the defrost sensor with the preset freezing temperature when the refrigerator 1 is powered on to determine whether the refrigerator 1 currently meets the compressor start-up conditions. When the compressor start-up conditions are not met, the compressor is controlled to start with a delay to avoid structural damage to the compressor when it is started when the pressure difference is large. When the compressor start-up conditions are met, the compressor is controlled to start immediately to enable the refrigerator 1 to quickly respond to the normal refrigeration start-up instruction or the factory inspection instruction, thereby better balancing the normal refrigeration start-up and factory inspection processes, and ensuring that the refrigerator 1 can quickly complete the power-off restart and factory inspection processes.

[0038] like Figure 2 As shown, in some embodiments, after S30, the refrigerator control method may include S40 to S60 to accurately control the refrigerator 1 to start refrigeration normally or enter the factory inspection instruction according to the control intention.

[0039] S40: Determine whether the door of the refrigerator 1 is opened.

[0040] Here, whether the door is opened can be detected by a door switch sensor provided on the door of the refrigerator 1. In addition to the freezer, the refrigerator 1 can also be provided with a refrigeration chamber; accordingly, the freezer and the refrigeration chamber can be provided with doors respectively. Further, it can be determined whether the door of the freezer and / or the refrigeration chamber is opened.

[0041] S50: In response to determining that the door of the refrigerator 1 is not opened, controlling the refrigerator 1 to sequentially execute a commodity inspection program and a refrigeration program.

[0042] After the compressor is controlled to start immediately, if it is determined that the door of the refrigerator 1 is not opened, it can be determined that the refrigerator 1 has not been powered on before the current power-on, the current power-on is the first power-on, and the refrigerator 1 is in the commodity inspection stage before leaving the factory. At this time, the refrigerator 1 can be controlled to execute the pre-set commodity inspection program and refrigeration program in sequence, so that each component of the refrigerator 1 is operated in sequence according to the operating parameters set in the commodity inspection program and the refrigeration program, thereby controlling the refrigerator 1 to complete the factory inspection, so as to determine whether the refrigerator 1 meets the factory qualification standards.

[0043] S60: In response to determining that the door of the refrigerator 1 is opened, controlling the refrigerator 1 to skip the commodity inspection procedure and directly execute the refrigeration procedure.

[0044] After the compressor is controlled to start immediately, if it is determined that the door of the refrigerator 1 is opened, it can be determined that the refrigerator 1 is powered on again after being shut down for a long time. At this time, the refrigerator 1 can be controlled to skip the commodity inspection procedure and directly execute the refrigeration procedure, so that each component of the refrigerator 1 operates according to the operating parameters set in the refrigeration program to meet the user's normal startup refrigeration and fresh-keeping needs.

[0045] The specific steps for controlling the delayed start of the compressor can be determined according to actual needs, and the embodiments of the present application do not limit this. Figure 3 As shown, in some embodiments, S20 may include S21-S22.

[0046] S21: Control the compressor to continue to remain in the stopped state.

[0047] S22: In response to the compressor shutdown time since the refrigerator 1 is powered on reaching the preset shutdown time, the compressor is controlled to start immediately, and the refrigerator 1 is controlled to skip the commodity inspection procedure and directly execute the refrigeration procedure.

[0048] Here, the preset downtime duration can be pre-set in the control system of the refrigerator 1 to determine whether the pressure difference of the compressor has been completely eliminated or reduced to a safe range. The value of the preset downtime duration can be determined according to actual needs, and the embodiment of the present application is not limited to this; for example, the value range of the preset downtime duration can be 7 to 9 minutes, and the preset downtime duration can be set to, for example, 7 minutes, 7.5 minutes, 8 minutes, 8.5 minutes or 9 minutes.

[0049] When the shutdown time of the compressor since the refrigerator 1 is powered on reaches the preset shutdown time, it can be determined that the pressure difference of the compressor has been completely eliminated or reduced to a safe range; at this time, the compressor can be controlled to start immediately, and the refrigerator 1 can be controlled to skip the commercial inspection procedure and directly execute the refrigeration program, so that the various components of the refrigerator 1 operate according to the operating parameters set by the refrigeration program to meet the user's normal startup refrigeration and preservation needs.

[0050] like Figure 4 As shown, in some embodiments, S20 may include S21 ′ to S24 ′.

[0051] S21': Control the compressor to continue to remain in the stopped state.

[0052] S22': Determine whether the refrigerator 1 is powered on for the first time.

[0053] S23': In response to determining that the refrigerator 1 is powered on for the first time, when the shutdown time of the compressor since the refrigerator 1 is powered on reaches a preset shutdown time, the compressor is controlled to start immediately, and the refrigerator 1 is controlled to skip the commodity inspection procedure and directly execute the refrigeration procedure.

[0054] When it is determined that the refrigerator 1 is powered on for the first time, that is, it has not been powered on and running before the current power-on, when the shutdown time of the compressor since the refrigerator 1 is powered on reaches a preset shutdown time, the compressor can be controlled to start immediately, and the refrigerator 1 can be controlled to skip the commodity inspection procedure and directly execute the refrigeration procedure.

[0055] S24': In response to determining that the refrigerator 1 is not powered on for the first time, when the downtime of the compressor since the last power failure of the refrigerator 1 reaches a preset downtime, the compressor is controlled to start immediately, and the refrigerator 1 is controlled to skip the commodity inspection procedure and directly execute the refrigeration procedure.

[0056] When it is determined that this is not the first time that refrigerator 1 is powered on, that is, it has been powered on and powered off before the current power-on, the compressor can be controlled to start immediately when the shutdown time since the last power-off of refrigerator 1 reaches a preset shutdown time, and refrigerator 1 can be controlled to skip the commercial inspection procedure and directly execute the refrigeration procedure.

[0057] By setting S21'~S24', the refrigerator control method provided in the embodiment of the present application can control the compressor to start after the downtime time since the refrigerator 1 is powered on reaches a preset downtime time when the refrigerator 1 is powered on for the first time, and control the compressor to start after the downtime time since the refrigerator 1 was last powered off reaches a preset downtime time when the refrigerator 1 is not powered on for the first time. This can ensure the safety and reliability of the compressor startup, effectively shorten the downtime time of the compressor, control the compressor to start quickly within a short time after the refrigerator 1 is powered on, and improve the startup response rate of the compressor.
