103. When the cold accumulation temperature is lower than a first temperature threshold value, controlling a first air door to be opened;
when the cold storage temperature is lower than the first temperature threshold, it indicates that the temperature of the cold storage medium is low enough to meet the standard of temperature regulation and control of the outside air, and the first damper is controlled to open, please refer to fig. 5, for example, the opening mode of the first damper is that the first damper rotates 180 degrees counterclockwise when the first damper is in a closed state, and different opening modes can be set according to actual application conditions, which is not limited herein.

Example two
For convenience of understanding, an embodiment of a novel refrigerator control method is provided below for explanation, and in practical application, whether it is appropriate to perform air replacement in the refrigerating compartment is comprehensively considered by combining the power-on time of the refrigerator, the actual temperature condition of the refrigerating compartment and the set temperature of the refrigerating compartment, so as to avoid the condition that the refrigerating compartment is frequently started due to the temperature rise or non-uniformity.
Fig. 2 is a schematic flow chart of an embodiment of a novel refrigerator control method in the embodiment of the present application.
Referring to fig. 2, an embodiment of the novel refrigerator control method in the embodiment of the present application includes:
201. comparing the electrifying time with a preset time;
the power-on duration refers to a duration recorded after the refrigerator is powered on, in the embodiment of the present application, the power-on duration can be reset, the reset time point may be a time when the refrigerator is detected to start to operate according to a preset refrigeration temperature control strategy, and the reset time point may also be changed according to an actual situation in an actual application, which is not limited herein.
In the embodiment of the application, a threshold for judging whether the energization time length reaches the standard is preset, that is, the preset time length, for example, the preset time length can be set to 2 hours, that is, if the energization time length is greater than the preset time length by default, the energization time length of the refrigerator is considered to reach the standard, the operation state of the refrigerator is relatively stable, and the next judgment step can be executed; if the power-on duration is less than the preset duration, the power-on duration of the refrigerator is considered to be not up to the standard, the running state of the refrigerator may not be stable, the detected data may have deviation, and the refrigerator needs to be continuously operated for a period of time and then judged to obtain more accurate detection data.
202. Comparing the compartment temperature difference with a second temperature threshold;
in the embodiment of the present application, the compartment temperature difference refers to a difference between a refrigerating compartment temperature and a set refrigerating temperature, referring to fig. 4 and 5, the refrigerating compartment temperature is obtained by detecting a temperature sensing bulb disposed in the refrigerating compartment in real time, and the set refrigerating temperature refers to a temperature set by a user for a refrigerator.
In the embodiment of the application, a temperature threshold for judging the magnitude of the compartment temperature difference, namely a second temperature threshold, is preset, and for example, the second temperature threshold may be set to be 2 ℃, that is, if the compartment temperature difference is greater than the second temperature threshold by default, the temperature of the refrigerating compartment is considered to be slightly higher than the set refrigerating temperature set by the user; if the temperature difference of the compartments is smaller than the second temperature threshold value, the temperature of the refrigerating compartments is considered to be lower than the set refrigerating temperature set by a user, the temperature condition of the refrigerating compartments is ideal, only continuous detection is needed, and the operation state of the refrigerator does not need to be changed.
203. When the temperature difference of the compartment is greater than a second temperature threshold value, controlling the first fan and the second air door to be opened;
when the temperature difference of the compartment is greater than the second temperature threshold value, the temperature of the refrigerating compartment is considered to be slightly higher than the set refrigerating temperature set by a user, the operation state of the refrigerator needs to be adjusted, and the temperature of the refrigerating compartment is regulated and controlled. If the temperature of the refrigerating chamber is higher than the set refrigerating temperature without adjustment, the air replacement process is executed, and the introduction of the external air causes the temperature of the refrigerating chamber to further rise, thereby affecting the fresh-keeping effect of the refrigerating chamber and increasing the burden of refrigerating parts such as a compressor and the like.
Referring to fig. 4 and 5, the first fan may be disposed at a top of the component where the refrigerating medium is located, and is set according to an actual application situation, which is not limited. After the first fan is started, on one hand, cold air in the refrigerating medium is blown out, the temperature of the refrigerating chamber is reduced, on the other hand, the temperature field of the refrigerating chamber is disturbed, the temperature of each position in the refrigerating chamber is uniformly distributed, the temperature of the refrigerating chamber obtained by the temperature sensing bag of the refrigerating chamber is more accurate, and meanwhile, the negative influence caused by the sinking of the cold air is avoided.
Referring to fig. 5, the second damper is used to introduce cold air into the freezing chamber. For example, the opening mode of the second damper is that the second damper rotates 90 degrees counterclockwise when in the closed state, and different opening modes can be set according to practical application situations, which is not limited herein. After the second air door is opened, the cold air of the freezing chamber can enter the part where the cold storage medium is located through the second air door, one part of cold energy of the cold air of the freezing chamber can be absorbed and stored by the cold storage medium, one part of cold energy can be blown out through the first fan, and one part of cold energy can be conveyed to the cold storage chamber through other air outlets on the part where the cold storage medium is located, so that the temperature of the cold storage chamber is reduced.
204. Comparing the set refrigeration temperature with a gear preset temperature, and determining a first temperature threshold;
in the embodiment of the application, a threshold for judging the set refrigerating temperature is preset, namely, the gear preset temperature, for example, the gear preset temperature can be set to 4 ℃, namely, if the set refrigerating temperature is greater than the gear preset temperature, the set refrigerating temperature is considered to be high, the temperature of the refrigerating chamber which changes along with the set refrigerating temperature is considered to be relatively high correspondingly, and the requirement for reducing the temperature of the outside air entering the refrigerating chamber is reduced; if the set refrigerating temperature is higher than the gear preset temperature, the set refrigerating temperature is considered to be low, the temperature of the refrigerating chamber changing along with the set refrigerating temperature is correspondingly considered to be low, and the requirement for reducing the temperature of the outside air entering the refrigerating chamber is increased.
Due to the diversity of cooling requirements, there are different requirements for the cooling capacity of the cold storage medium, and therefore it can be understood that the first temperature threshold includes, but is not limited to, a first cold storage threshold and a second cold storage threshold, and the first cold storage threshold is smaller than the second cold storage threshold.
If the set refrigeration temperature is lower than the gear preset temperature, comparing the cold accumulation temperature with a first cold accumulation threshold, for example, the first cold accumulation threshold can be set to 1 ℃; if the set refrigerating temperature is higher than the shift preset temperature, the cold storage temperature is compared with a second cold storage threshold, and the second cold storage threshold may be set to 3 ℃.
The following beneficial effects can be seen from the second embodiment:
whether the refrigerator is in a stable state is determined through judgment of the electrifying time, the compartment temperature difference is compared with the second temperature threshold value in the stable state, when the compartment temperature difference is larger than the second temperature threshold value, the first fan and the second air door are controlled to be opened, and after the refrigerating compartment temperature is regulated, the first temperature threshold value is determined according to a comparison result of the set refrigerating temperature and the gear preset temperature. Compared with the prior art, the scheme of the embodiment of the application can increase the judgment on the stability of the refrigerator and ensure the accuracy of the detection data; the temperature difference control is added to realize the regulation and control of the temperature of the refrigerating chamber, the uniformity of the temperature of the refrigerating chamber is improved through the disturbance of the fan, the preservation effect and the preservation range of the refrigerating chamber are ensured, meanwhile, a precondition is provided for replacing the air of the refrigerating chamber, the problem of frequent refrigeration caused by excessive temperature rise of the refrigerating chamber due to the introduction of external fresh air is avoided, and the energy efficiency of the refrigerator is improved; the judgment on the external air cooling requirement is increased, the cold storage medium is ensured to reach the target cold storage temperature threshold value, the cooling capacity of the cold storage medium is ensured, the temperature fluctuation of the cold storage room caused by the external air is avoided to be large, and the problem of preservation failure is avoided.

301. controlling the first air door to open and recording the running time of the first fan after the first air door is opened;
and recording the running time of the first fan after the first air door is opened for recording the duration of executing the air replacement operation.

302. Comparing the operation time with a preset operation time;
in the embodiment of the application, a threshold value for judging whether the operation time of the first fan after the first air door is opened meets the requirement or not, namely the preset operation time is preset and serves as a standard that the operation time meets the requirement, namely the default condition is that if the operation time is longer than the preset operation time, the duration for executing the air replacement operation is considered to meet the requirement; if the operation duration is longer than the preset operation duration, the duration for executing the air replacement operation is considered to meet the requirement, and the air replacement operation needs to be continuously executed.
For example, the preset operation time may be set to 10 minutes or 15 minutes, and needs to be set according to other practical application conditions such as the set refrigeration temperature, and assuming that the current set refrigeration temperature is lower, for example, lower than 4 ℃, it is indicated that the duration of the replaced air cannot be too long, otherwise, the temperature of the refrigeration compartment rises too much, and the refrigeration components such as the compressor are triggered to start during the air replacement, so that the preset operation time may be set to any time within 8 to 12 minutes; assuming that the current set refrigeration temperature is high, illustratively above 4 ℃, the preset run time period can be set to any time period within 13 to 17 minutes.
It should be understood that the setting manner of the preset operation time period is only exemplary, and the setting manner of the preset operation time period is various and needs to be set specifically according to the actual application, and the setting manner is not limited to the only setting method.
303. When the operation time length is longer than the preset operation time length, controlling the first air door to be closed and controlling the refrigerator to operate according to a preset refrigeration temperature control strategy;
when the running time is longer than the preset running time, the air in the refrigerating chamber is fully replaced, the first air door is controlled to be closed, the introduction of the external air is stopped, the refrigerator can return to the conventional running state executed according to the preset refrigerating temperature control strategy, the second fan is controlled to be opened, the second fan is a freezing fan and used for blowing cold air in the refrigerating part to reduce the temperature of the refrigerating chamber, and the third air door is controlled to be opened and used for conveying the cold air of the second fan to the refrigerating chamber to reduce the temperature of the refrigerating chamber.
The following beneficial effects can be seen from the third embodiment:
the deodorization device is characterized in that the outside air is filtered and sterilized through the deodorization block, the duration time for executing air replacement is controlled through comparison of the operation duration time and the preset operation duration time, and when the preset operation duration time is reached, air replacement is stopped and the air replacement is operated according to a preset refrigeration temperature control strategy.
