Drawings
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention. In the drawings:
fig. 1 is a schematic block diagram of a refrigerator purge control method according to an embodiment of the present invention.
Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
As shown in a block diagram of fig. 1, in a refrigerator purification control method provided by the present invention, a refrigerator is provided with a compressor, an electrified purification module and a fan, wherein the refrigerator purification control method includes identifying an operating state of the compressor of the refrigerator, and controlling an on-off ratio of the electrified purification module of the refrigerator and an operation and a stop of the fan according to the operating state of the compressor, wherein the on-off ratio is a ratio of an on-time to an off-time of the electrified purification module.
In the technical scheme, the on-off ratio of the electrified purification device of the refrigerator (namely, the on-off purification time of the electrified purification device) and the operation of the fan can be controlled according to the working state of the compressor of the refrigerator, so that the compressor of the refrigerator is fully utilized, a special air detection sensor is not required to be arranged, the cost of the refrigerator is remarkably reduced, and the air in the refrigerator can be efficiently purified.
Further, in order to better control the operation of the electrified purification module and the fan according to the working state of the compressor and improve the purification effect under different conditions, preferably, the electrified purification module and the fan are controlled independently. Of course, it should be understood herein that both the energization purifying module and the blower fan may be implemented by the control unit of the refrigerator.
In addition, in order to more timely and accurately determine the operating state of the compressor, it is preferable that the control unit automatically identifies the on-time rate of the compressor in a unit time, and compares the identified on-time rate in the unit time with the on-time rate preset in the control unit to determine the operating state of the compressor, so that the on-time rate of the compressor can more intuitively determine the operating state of the compressor during the operation of the refrigerator.
It should be understood that the predetermined on-time value may be a specific value, such as 50%, 60% or 70%, or preferably, the predetermined on-time value is a range value, such as 50% to 70%. Thus, the compressor can be determined to be in a normal working state as long as the recognized on-time rate in unit time falls within the range value.
For example, if the control unit determines that the identified on-time rate in unit time meets the preset on-time rate, for example, falls into the range value, the control unit determines that the compressor is in a normal working state, and further determines whether the refrigerator is in a daytime working state or a nighttime working state, because the operation of the refrigerator is different between the daytime working state and the nighttime working state.
Further, whether the refrigerator is in a daytime working state or a nighttime working state can be detected through an infrared sensor on the refrigerator. In this way, the control unit can accurately determine the specific operating state based on the infrared sensor.
For example, if the refrigerator is in a daytime working state, because the frequency of opening the refrigerator by a user is high during the daytime, and when the refrigerator is opened, the inside of the refrigerator can be exchanged with outside air, so as to improve the air effect inside the refrigerator, the on-off ratio of the electrified purification module is less than or equal to 1, that is, the on-time of the electrified purification module is less than or equal to the off-time, so that more energy is saved.
Of course, in the daytime working state, in order to achieve better purification effect, it is preferable that the blower is operated for a preset time T1 before the power-on purification module, so that the blower can disturb the airflow in the refrigerator and ensure the uniformity of the wind field inside the refrigerator, and/or the blower is stopped for a preset time T2 after the power-on purification module is delayed, so that the blower can uniformly blow the purified air to all corners inside the refrigerator as much as possible and achieve more uniformity of air purification inside the refrigerator.
Of course, the preset times T1 and T2 can be selected according to the requirement, such as the preset time T1 is 3-10 minutes, the preset time T2 is 5-35 minutes, preferably, the preset time T1 is 5 minutes, and the preset time T2 is 30 minutes. Of course, it should be understood that the preset times T1 and T2 may be other values, and the invention is not limited thereto.
For example, if the refrigerator is in a night working state, at night, the refrigerator door is not opened basically or the opening frequency is very low, at this moment, the air in the refrigerator is relatively fixed and cannot be ventilated through the opened refrigerator door and the outside in time, at this moment, the on-off ratio of the power-on purification module is greater than 1, that is, the on-time of the power-on purification module is greater than the off-time, so that better purification is realized, and the energy conservation and the energy consumption reduction can be realized when the fan is stopped.
If the identified on-time rate in unit time is not consistent with the preset on-time rate, for example, the on-time rate in unit time is far lower than the preset on-time rate, the compressor is judged to be in an abnormal working state, for example, when the on-time rate in unit time is larger than the preset on-time rate, the refrigerator is in busy refrigeration operation, at the moment, the air in the refrigerator is poor, the on-off ratio of the electrified purification module is larger than 1, and the fan and the electrified purification module run synchronously, so that the on-time of the electrified purification module is larger than the off-time, and the fan runs synchronously, so that a better and more comprehensive purification effect is realized;
and when the recognized on-time rate in unit time is less than half of the preset on-time rate, for example, the on-time rate in unit time is far less than the preset on-time rate or the compressor is not started, the power-on purification module and the fan are stopped, so that energy is saved and energy consumption is reduced.
In addition, according to the refrigerator purification control method, when the refrigerator door is opened, the fan and the electrified purification module stop working immediately, so that air in the refrigerator and outside air can be naturally exchanged, and energy consumption is reduced; and/or, when the voltage of the refrigerator is abnormal, the electrified purification module stops working to be in a self-protection state, and the fan stops after delaying the preset time T3 to convey purified air to all corners of the inside of the refrigerator, so that more uniformity of air purification in the inside of the refrigerator is realized. Preferably, the preset time T3 is 5-35 minutes, and preferably, the preset time T3 is 30 minutes. Of course, it should be understood that the preset time T3 can be other values, and the invention is not limited thereto.
Finally, the present invention provides a refrigerator capable of implementing any of the above described refrigerator purge control methods. Therefore, the production cost of the refrigerator is obviously reduced, and the refrigerator has an efficient air purification effect, so that the overall quality of the refrigerator is obviously improved.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the above embodiments, and various simple modifications can be made to the technical solution of the present invention within the technical idea of the present invention, and these simple modifications are within the protective scope of the present invention.
It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. The invention is not described in detail in order to avoid unnecessary repetition.
In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
