Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, an embodiment of the present invention provides a method for controlling a refrigerator, including: confirming that the refrigerator does not carry out a defrosting process; acquiring the content of organic matters in the air in the refrigerating chamber, if the content of the organic matters exceeds a threshold value or the running time of the refrigerator exceeds a set time, guiding the air outside the refrigerator body of the refrigerator into the freezing chamber, then guiding the air into the refrigerating chamber from the freezing chamber, and discharging the air in the refrigerating chamber out of the refrigerator body of the refrigerator.
The control method in the embodiment of the invention is preferably used for a single-system refrigerator. The freezing chamber can be one or a plurality of freezing chambers; the refrigerating chamber may be one or more. The refrigerating chamber can be a conventional refrigerating chamber at present, and can also be a storage chamber with other functions.
When a plurality of freezing chambers and a plurality of refrigerating chambers are arranged, at least one freezing chamber is internally provided with a refrigerating device. The following description will be given taking as an example a conventional structure in which a freezing chamber and a refrigerating chamber are provided, the freezing chamber being located below the refrigerating chamber.
When the refrigerator is defrosting, the refrigerator can be normally operated. When the refrigerator is not defrosted, the air outside the refrigerator body is guided into the freezing chamber and the refrigerating chamber according to the content of organic compounds (VOC) in the refrigerating chamber or the running time t of the refrigerator; the air introduced into the freezing chamber and the refrigerating chamber is diffused in the freezing chamber and the refrigerating chamber, and the air in the refrigerator body of the refrigerator is discharged out of the refrigerator, so that the aims of air exchange and odor removal are fulfilled. However, depending on the content of other substances in the refrigerating chamber, air outside the refrigerator body may be introduced into the freezing chamber and the refrigerating chamber. The organic content will be described below as an example.
The method for confirming whether the refrigerator needs defrosting or not can be realized by a conventional judgment mode, and an improved scheme can be adopted as long as whether the refrigerator starts defrosting or enters the defrosting process can be confirmed.
The air introduced into the freezing chamber is diffused in the freezing chamber and the refrigerating chamber and then discharged out of the refrigerator through an outlet provided in the refrigerator. The outlet for discharging the air inside the cabinet is preferably provided at the top of the refrigerating compartment, and may be one or more. It can be understood that when the ventilation is finished, the channel of the refrigerator body for introducing or exhausting gas is closed, so as to avoid affecting the refrigeration efficiency of the refrigerator. Wherein the air introduced into the freezing chamber and the refrigerating chamber can be diffused in the storage spaces of the freezing chamber and the refrigerating chamber.
The air outside the refrigerator body is guided into the freezing chamber, diffused in the freezing chamber and the refrigerating chamber and immediately discharged out of the refrigerator body of the refrigerator, and the channel guided into the refrigerator and discharged out of the refrigerator forms a channel for air circulation in the refrigerator body, so that the aims of air exchange and odor removal are fulfilled; meanwhile, the refrigeration effect of the refrigerator is prevented from being influenced by the fact that air with relatively high temperature stays in the freezing chamber and the refrigerating chamber for a long time. In addition, in the air exchange and odor removal processes, air outside the refrigerator can enter the refrigerator to circulate, and a certain defrosting effect is achieved.
When the organic matter content in the refrigerating chamber does not exceed the threshold value and the operation time is long, there is a possibility that the refrigerator may have odor due to the large amount of the stored goods in the refrigerator. At this time, air outside the refrigerator is directly introduced into the freezing chamber, and the air is exchanged with the freezing chamber and then introduced into the refrigerating chamber, so that the freezing chamber and the refrigerating chamber are sufficiently exchanged with air and deodorized. The air introduced into the freezing chamber and the refrigerating chamber is timely discharged out of the refrigerator body of the refrigerator through an outlet of the refrigerating chamber, and the influence on the refrigerating efficiency of the refrigerator due to the fact that high-temperature gas stays for a long time is avoided. The set time t may be preset or may be set according to the change of the organic content in the freezing chamber and the refrigerating chamber.
The ventilation process of the refrigerator is controlled by the content of organic matters in the air in the refrigerating chamber of the refrigerator and the running time of the refrigerator, so that the ventilation efficiency of the refrigerator can be improved, and the influence on the refrigeration efficiency caused by frequent ventilation of the refrigerator can be avoided.
In one embodiment, if the organic content in the refrigerating chamber exceeds a threshold value, an outlet of a first duct for introducing air outside the refrigerator into the freezing chamber communicates with the freezing chamber and is adjacent to a lower portion of a refrigerating device in the freezing chamber. In addition to the above embodiments, the present embodiment specifically describes a control method when the content of organic substances in the refrigerating chamber exceeds a threshold value.
After the air introduced into the freezing chamber is diffused and ventilated in the freezing chamber, the air in the freezing chamber is introduced into the refrigerating chamber, and the air in the refrigerating chamber is discharged out of the refrigerating chamber to be discharged out of the refrigerator, so that the exchange of the air in the refrigerating chamber and the external air is realized, and the purposes of ventilation and deodorization are achieved.
In addition, in the process of introducing air outside the refrigerator into the freezing chamber and discharging air in the refrigerating chamber out of the refrigerator body of the refrigerator, ventilation channels are formed between the freezing chamber and the refrigerating chamber and the external environment, and the ventilation channels are more beneficial to the circulation of air inside the refrigerator.
Wherein, a first air duct may be provided at a sidewall of the freezing chamber for introducing air from an outside of the refrigerator into the freezing chamber. The outlet of the first air channel is communicated with the freezing chamber, is preferably arranged at the lower part of the freezing chamber and is close to the lower part of the refrigerating device, so that the air exchange efficiency in the freezing chamber is improved, the air in the freezing chamber is conveniently discharged out of the freezing chamber, enters the refrigerating chamber and is further discharged out of the refrigerator through the refrigerating chamber.
The threshold value in each of the above embodiments may be preset, may be changed according to the type of the stored article, or may be adaptively changed according to the change of the organic matter content in the refrigerating chamber.

And in the first sub-air flue and the second sub-air flue which are arranged side by side, only the second sub-air flue is internally provided with an airflow driving mechanism. When leading-in air in to the freezer by the outside of refrigerator, first sub-wind channel is closed, and the sub-wind channel of second is opened, and airflow actuating mechanism also opens, and airflow actuating mechanism can provide the negative pressure in for the freezer, makes the air in the freezer leading-in to the freezer fast, and the air discharge refrigerator in the freezer improves the ventilation in the freezer, removes flavor efficiency.
