The present embodiment discloses a refrigerator, referring to fig. 1, having a cabinet 100 and a door 200 hinged to the cabinet 100, the cabinet 100 and the door 200 together defining a refrigerating/freezing space.
The case 100 includes a housing 110 and a liner (not shown), and a foaming layer 120 is provided between the housing 110 and the liner.
The refrigerator has a refrigerating chamber and a freezing chamber arranged up and down. The lower part of the box body is provided with a compressor and a refrigerating fan, and the refrigerating fan is used for conveying cool air to the refrigerating chamber. The upper position of the box body is provided with a refrigerating fan which is used for conveying cool air to the refrigerating chamber.
When the refrigerator works, refrigeration related components such as a compressor, a refrigerating fan and the like work, vibration is generated during working, the vibration is transmitted to the refrigerator body, and vibration noise is generated by the refrigerator body.
The refrigerator further includes a vibration receiver 600 and an electromagnetic actuator 300, and the vibration receiver 600 and the electromagnetic actuator 300 are provided on the cabinet 100.
The vibration receiver 600 is used to receive vibration generated by the cabinet 100 when the refrigerator is in operation, and to perform acoustic spectrum analysis on the vibration.
The electromagnetic exciter 300 is used for driving the box body 100 to vibrate and sound, and sound waves of the sound emitted by the box body 100 under the action of the electromagnetic exciter 300 are in constant amplitude opposite phase with sound waves obtained by analysis of the vibration receiver 600, and two kinds of noise are offset, so that the effects of silencing and noise reduction are achieved.
The refrigerator utilizes the electromagnetic exciter 300 to actively generate vibration, achieves the effect of active noise elimination and noise reduction, and has the advantages of more direct and effective noise reduction and good noise reduction effect.
The realization means of the active noise reduction has no influence on the existing parts of the refrigerator, the refrigeration system and the like.
In some embodiments of the present application, electromagnetic actuator 300 operates intermittently.
That is, every time a certain period of time, the electromagnetic exciter 300 stops operating, the vibration receiver 600 again collects the vibration signal of the tank body 100, and the electromagnetic exciter 300 again operates according to the newly collected frequency band, so as to ensure the accuracy of active noise elimination and noise reduction.
In some embodiments of the present application, a refrigerator has a normal operation mode and an abnormal operation mode.
The normal operation mode means that the refrigerator is in a normal refrigeration operation state, at this time, vibration generated by the compressor, the refrigerating fan and other parts is stable, the vibration receiver can stop working in the state, and the electromagnetic exciter 300 vibrates in a wide range preset by the system, so that a stable noise reduction effect is realized.
The non-conventional modes of operation include a cryogenic mode, a rapid refrigeration mode, and the like.
In the refrigerator in the non-conventional operation mode, the vibration receiver 600 operates to continuously collect vibration noise information of the refrigerator, and the electromagnetic exciter 300 intermittently operates to vibrate to generate vibration sound waves having the same amplitude and opposite phase to the noise information, thereby achieving noise elimination and noise reduction.
In some embodiments of the present application, the electromagnetic actuators 300 have four, and two electromagnetic actuators 300 are respectively disposed on the left and right side walls of the case 100, and two electromagnetic actuators 300 disposed on the same side of the case 100 are disposed above and below.

The electromagnetic exciter 300 and the vibration receiver 600 which are distributed up and down correspond to the positions of the parts which mainly generate vibration noise, such as the compressor, the refrigerating fan and the like in the refrigerator, and can generate better noise elimination and noise reduction effects.
When the refrigerator is in a deep cooling mode, the running power of the compressor and the refrigerating fan at the lower part can be increased, the vibration is larger, the electromagnetic exciter 300 and the vibration receiver 600 at the lower part work, the vibration receiver 600 at the lower part is used for collecting vibration noise information generated by the compressor and the refrigerating fan at the lower part, and the electromagnetic exciter 300 at the lower part is used for driving the box body at the lower part to generate vibration sound waves with the same amplitude opposite to the noise information, so that noise elimination and noise reduction are realized.
Further, when the refrigerator enters the initial stage of the deep cooling mode, the vibration of the compressor and the fan is not very large, at this time, the electromagnetic exciter 300 located above and below can vibrate by a wide range initially set by the system, after the refrigerator enters the deep cooling mode for a period of time, the electromagnetic exciter 300 located above stops working, and the electromagnetic exciter 300 located below and the vibration light receiver 600 start working again, so that better noise elimination and noise reduction effects are achieved, and energy conservation can be achieved.
In some embodiments of the present application, when the refrigerator is in the fast cooling mode, the cooling fan above will increase the operating power, and the electromagnetic exciter 300 and the vibration receiver 600 above will work to generate better noise elimination and reduction for the upper box.
In some embodiments of the present application, when the refrigerator is in the holiday mode in the non-normal operation mode, since no person is in the room, the noise reduction process is not required for the refrigerator, so that the electromagnetic exciter 300 and the vibration receiver 600 stop working, thereby realizing energy saving.
