Referring to fig. 2, fig. 2 is a schematic view showing a structure of a refrigerating system in a refrigerator 100 according to an embodiment of the present invention, the refrigerating system including a compressor 10, a condenser 2, an anti-condensation pipe 3, a dry filter 4, a capillary 5, an evaporator 6, and a gas-liquid separator 7. The working processes of the refrigeration system comprise a compression process, a condensation process, a throttling process and an evaporation process.
The compression process comprises the following steps: when the power line of the refrigerator is inserted and the contact of the temperature controller is connected, the compressor 1 starts to work, the low-temperature and low-pressure refrigerant is sucked by the compressor 1, compressed into high-temperature and high-pressure overheat gas in the cylinder of the compressor 1 and then discharged to the condenser 2; the condensation process is as follows: the high-temperature and high-pressure refrigerant gas radiates heat through the condenser 2, the temperature is continuously reduced, the refrigerant gas is gradually cooled into normal-temperature and high-pressure saturated steam, the saturated steam is further cooled into saturated liquid, the temperature is not reduced any more, the temperature at the moment is called as condensing temperature, and the pressure of the refrigerant in the whole condensing process is almost unchanged; the throttling process is as follows: the condensed refrigerant saturated liquid is filtered by a dry filter 4 to remove moisture and impurities, and then flows into a capillary tube 5, throttling and depressurization are carried out through the capillary tube, and the refrigerant is changed into normal-temperature and low-pressure wet vapor; the evaporation process is as follows: the wet vapor with normal temperature and low pressure starts to absorb heat in the evaporator 6 for vaporization, so that the temperature of the evaporator and the surrounding temperature are reduced, the refrigerant is changed into low-temperature and low-pressure gas, the refrigerant coming out of the evaporator 6 returns to the compressor 1 again after passing through the gas-liquid separator 7, the process is repeated, and the heat in the refrigerator is transferred into the air outside the refrigerator, so that the purpose of refrigeration is realized.
Referring to fig. 3, fig. 3 is a schematic view of a position of a wind direction provided by an embodiment of the present invention, and fig. 3 shows a side surface of the refrigerator 100, where the refrigerator 100 includes a refrigerating chamber 101, a freezing chamber 102, and a fan 8, and the fan 8 is configured to convey cold air flowing out of the evaporator 6 after heat exchange, and to convey the cold air into a refrigerating duct and a freezing duct, respectively, and then enter the refrigerating chamber and the freezing chamber through an air outlet of a duct path.
Referring to fig. 4, fig. 4 is a flowchart illustrating operations of a controller in a refrigerator according to an embodiment of the present invention, the controller being configured to:
s101, acquiring the ambient temperature detected by an ambient temperature detection device and acquiring door opening information of a refrigerator compartment; the door opening information comprises door opening compartments, door opening time and door opening times of the compartments in the current time period;
S102, acquiring a corresponding ring temperature correction coefficient according to the ambient temperature, and acquiring a corresponding door opening correction coefficient according to the door opening information;
s103, calculating a refrigerator door opening weighted value in the current time period according to a preset weighted value calculation model according to the loop Wen Xiuzheng coefficient, the door opening correction coefficient, the door opening duration and the door opening times;
s104, judging whether the refrigerator door opening weighted value meets a preset abnormal door opening condition or not;
S105, if the refrigerator door opening weighted value meets the abnormal door opening condition, the rotating speed of the compressor is increased to a preset high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a preset limit interval duration;
and S106, if the refrigerator door opening weighted value does not meet the abnormal door opening condition, adopting other control logic to control the compressor and defrosting interval duration.
Specifically, in step S101, the operation cycle of the refrigeration system includes two phases, namely a refrigeration phase and a defrosting phase, each phase having a corresponding operation duration. When the refrigerator 100 is powered on, the ambient temperature detecting device 20 is started to start detecting the ambient temperature, and sends the detected ambient temperature to the controller 30, and the controller 30 starts to detect door opening information of doors of all compartments in the refrigerator at the same time. The controller 30 may detect door opening information of a refrigerator, for example, dividing 24 hours a day into 12 time periods, and then one time period occupies 2 hours, and the refrigerator counts door opening information within the 2 hours every 2 hours.
Specifically, in step S102, the ring Wen Xiuzheng coefficients are obtained by dividing a plurality of environmental temperature ranges, different environmental temperature ranges correspond to different ring temperature correction coefficients, the ring Wen Xiuzheng coefficients are in a proportional relationship with the level of the environmental temperature range, and the level of the environmental temperature range is in a proportional relationship with the environmental temperature; for example, the environment temperature range includes two ranges, namely T is less than or equal to 25 ℃ and T is more than 25 ℃, the influence of the environment temperature on the opening of the refrigerator is smaller under the condition of lower temperature, so that the corresponding ring temperature correction coefficient is 1 under the condition of T is less than or equal to 25 ℃, otherwise, the influence of the environment temperature on the opening of the refrigerator is larger under the condition of higher temperature, and the corresponding ring temperature correction coefficient is 1.2 under the condition of T is more than 25 ℃. It should be noted that, the values of the ring temperature correction coefficients provided in the embodiment of the present invention are only examples, and in actual use, the environmental temperature range may be divided into more than 3 values, and the corresponding ring temperature correction coefficients may also be other values, which are not limited specifically herein.
The door opening correction coefficient is determined according to the type of the compartment of the refrigerator, different door opening correction coefficients correspond to different compartments, and the door opening correction coefficient and the refrigerating capacity of the compartment are in a proportional relation; different types of compartments have different influences caused by the door opening, and if the compartments with lower temperatures are opened more times, the compartments with higher influences on the temperature of the compartments are caused more, for example, the door opening correction coefficient corresponding to the refrigerating compartment is 1, and the door opening correction coefficient corresponding to the freezing compartment is 3. It should be noted that, the values of the door opening correction coefficients provided in the embodiments of the present invention are only examples, and in actual use, the types of the compartments of the refrigerator 100 may include 3 or more than 3 compartments, for example, a fresh-keeping compartment, and the corresponding door opening correction coefficients may also be other values, which are not limited in detail herein.
Specifically, in step S103, the weighted value calculation model satisfies the following formula:
Wherein P is a refrigerator door opening weighted value in the current time period; n is the number of compartments of the refrigerator; q i is the ring temperature correction coefficient corresponding to the ith chamber at the current ambient temperature; m i is the door opening correction coefficient corresponding to the ith chamber; t i is the average door opening time length when the door body of the ith compartment is opened; h i is the total number of times the door of the ith compartment is opened during the current time period.
For example, after the door-open time length is obtained, an average door-open time length needs to be calculated, where the average door-open time length=total door-open time length/door-open times. And substituting the average door opening duration into the formula, wherein the calculated result can be referred to in Table 1.

Assuming that n=2, i=1 is expressed as a refrigerating chamber, and i=2 is expressed as a freezing chamber, the following example is given by the number 1: at this point, the ambient temperature T≤25℃,Q1＝Q2＝1,M1＝1,M2＝3,T1＝10,T2＝10,H1＝2,H2＝1, calculated P＝Q1M1T1H1+Q2M2T2H2＝1*1*10*2+1*3*10*1＝20+30＝50; is illustrated by the example of sequence number 5: at this time, the ambient temperature T>25℃,Q1＝Q2＝1.2,M1＝1,M2＝3,T1＝10,T2＝10,H1＝2,H2＝1, is calculated P＝Q1M1T1H1+Q2M2T2H2＝1.2*1*10*2+1.2*3*10*1＝24+36＝60.
Specifically, in step S104, it is necessary to determine whether the refrigerator door opening weighted value satisfies the abnormal door opening condition, if so, the process proceeds to step S105, and if not, the process proceeds to step S106.
Specifically, in step S105, the abnormal door opening conditions include a severe door opening condition and an extreme door opening condition, the high rotation speed includes a first high rotation speed and a second high rotation speed, and the limit interval period includes a first interval period and a second interval period; and increasing the rotation speed of the compressor to a preset high rotation speed in a preset time period, and shortening the defrosting interval of the refrigeration system in the current running period to a preset limit interval duration, wherein the method comprises the following steps of:
When the refrigerator door opening weighted value meets the severe door opening condition, the rotating speed of the compressor is increased to a first high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a first interval duration; when the refrigerator door opening weighted value meets the extreme door opening condition, the rotating speed of the compressor is increased to a second high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a second interval duration; the second high rotating speed is larger than the first high rotating speed, and the second interval duration is smaller than the first interval duration.
Illustratively, the extreme door opening condition is that the refrigerator door opening weight is greater than a first fixed value, for example, the first fixed value is 600, that is, P > 600 is satisfied; the severe door opening condition is that the refrigerator door opening weighted value is between a first fixed value and a second fixed value, and the second fixed value is smaller than the first fixed value, for example, the second fixed value is 200, namely, the P is more than or equal to 200 and less than or equal to 600. The second high rotation speed is 4000 revolutions or more, the first high rotation speed is between [3000-4000 ], the second interval duration is 12h, and the first interval duration (unit: h) Between (12, 18). The higher the rotating speed of the compressor is, the higher the refrigerating efficiency is, and the more frosting quantity of the evaporator is caused, at the moment, the defrosting interval is required to be shortened to timely defrost, and the phenomenon that the normal refrigeration of the refrigerator is influenced due to the fact that the excessive frosting quantity on the evaporator is avoided.
Specifically, in step S106, further reference may be made to fig. 5, in which the control logic of the controller 30 is further determined when the refrigerator does not satisfy the abnormal door opening condition. The controller 30 is also configured to:
s1061, judging whether the refrigerator door opening weighted value meets a preset common door opening condition, if yes, entering a step S1062, and if not, entering a step S1063.
S1062, when the door opening weighted value of the refrigerator meets a preset common door opening condition, controlling the rotating speed of the compressor to be kept at a preset target rotating speed, and controlling the defrosting interval of the refrigeration system in the current running period to be a preset target interval duration;
S1063-S1064, when the door opening weighted value of the refrigerator meets a preset door closing condition, controlling the rotating speed of the compressor to be kept at a preset normal rotating speed, and controlling the defrosting interval of the refrigerating system in the current running period to be a preset normal interval duration.
The normal door opening condition is that the door opening weighted value of the refrigerator is between a third fixed value and a second fixed value, and the third fixed value is smaller than the second fixed value, for example, the third fixed value is 80, namely, the condition that P is more than or equal to 80 and less than 200 is satisfied; and the door closing condition is that the door opening weighted value of the refrigerator is smaller than the third fixed value, namely P is smaller than 80. The target rotational speed is greater than the normal rotational speed, the target rotational speed is less than the high rotational speed, such as the target rotational speed having a value of [2000,3000 ], and the normal rotational speed is less than 2000 revolutions. The target interval duration is less than the regular interval duration, the target interval duration is greater than the limit interval duration, for example, the target interval duration (unit: h) has a value of [18,24 ], and the regular interval duration has a value of [24,30].
It should be noted that, the compressor rotation speed control corresponding to the normal door opening condition and the door closing condition may maintain a refrigeration stage, but only the compressor rotation speed corresponding to the abnormal door opening condition needs to maintain a preset time period (for example, 1 h), if the compressor is operated at a high rotation speed for a long time, the refrigerator is easy to be cooled too much, and the actual temperature of the compartment is further far less than the temperature set by the user, which may cause freezing of food in the refrigerating compartment, so after the compressor rotation speed is controlled to maintain at the preset rotation speed, the compressor rotation speed control corresponding to the normal door opening condition may be switched back, or the compressor rotation speed control corresponding to the door closing condition may also be switched back.
According to the above division of the door opening weighting values of the refrigerator, the refrigerator is operated in 4 operation modes, and table 2 can be referred to.
Table 2 refrigerator mode division
| Mode | Refrigerator door opening weighting value | Compressor rotation speed value (rotation) | Defrosting interval time length value (h) |
| Door closing mode | P＜80 | Conventional rotation speed is less than 2000 rotation | Regular interval duration: [24,30] |
| Common usage mode | 80≤P＜200 | Target rotation speed: [2000,3000) | Target interval duration: [18,24) |
| Bad use mode | 200≤P≤600 | First high rotational speed: [3000-4000) | First interval duration: (12,18] |
| Extreme use mode | P＞600 | The second highest rotation speed is more than 4000 | Second interval duration: 12 |
It is worth to be noted that, the abnormal door opening condition corresponds to the control logic with a higher priority than the normal door opening condition, and the normal door opening condition corresponds to the control logic with a higher priority than the door closing condition. Because the controller 30 divides the operation time period of the refrigerator in advance, if multiple door opening is detected in the current operation time period and the door opening weighted value of the refrigerator meets the extreme door opening condition, the rotation speed of the compressor can be increased to a second high rotation speed, for example 4500 rotation, in a preset time period (for example 1 h), and the defrosting interval duration of the current operation period is controlled to be 12h. If the refrigerator is in the defrosting stage, defrosting is stopped immediately and the refrigerator enters the refrigerating stage so as to make up the refrigerating capacity as soon as possible, at the moment, the compressor is started and maintains the rotating speed of 4500 revolutions in a preset time period (1 h), and the refrigerator is restored to the conventional rotating speed or the target rotating speed after 1 h; if the refrigerator is in the refrigeration stage and does not enter the defrosting stage, and the defrosting interval duration does not reach 12h, the rotating speed of the compressor is increased, and the defrosting interval duration of the defrosting stage to be entered next is set to be 12h; if the defrosting interval time reaches 12 hours, defrosting is immediately carried out after the rotation speed of the compressor is increased. If the abnormal door opening condition and the normal door opening condition are met at the same refrigeration stage, for example, the abnormal door opening condition is met in the first 2 hours and the normal door opening condition is met in the latter 2 hours, the corresponding control logic of the abnormal door opening condition is preferably executed at the moment, and after the control logic is executed, the control logic corresponding to the normal door opening condition is executed.
Compared with the prior art, the refrigerator disclosed by the embodiment of the invention has the advantages that whether the door opening times are too large is determined by monitoring the door opening times of a user, and the door opening times are too large, so that the temperature of a refrigerator compartment is too high, and food materials are not easy to store, and therefore, when the door opening times are too large, the refrigerating capacity of the refrigerator compartment needs to be timely supplemented, and the compartment temperature is prevented from being too high for a long time. In addition, in the embodiment of the invention, the compressor and the defrosting period are not controlled only through the door opening times, the ring Wen Xiuzheng coefficient and the door opening correction coefficient are introduced, the influence of different environment temperatures on the door opening of the refrigerator is different, when the environment temperature is lower, the temperature of the air which is externally gushed in when the refrigerator is opened is not too high, at the same time, the influence on the compartments is smaller, meanwhile, the door opening correction coefficient is related to the types of the compartments of the refrigerator, the influence on the door opening of the compartments of different types is different, if the door opening times of the compartments with lower temperature are more, the influence on the temperature of the compartments is larger, the door opening weighting value of the refrigerator is calculated through the ring Wen Xiuzheng coefficient and the door opening correction coefficient, so that whether the door opening times of the refrigerator is too large or not is determined, the cold loss caused by the fact that a user opens the door for a plurality of times is timely made up, and the temperature rise of the indoor articles in a low temperature state is not influenced by the door opening is ensured.
Referring to fig. 6, fig. 6 is a flowchart of a refrigerator control method according to an embodiment of the present invention, where the refrigerator control method according to the embodiment of the present invention is implemented by a controller in a refrigerator, and the refrigerator control method includes:
S1, acquiring the environmental temperature of the environment where the refrigerator is located, acquiring a corresponding ring temperature correction coefficient according to the environmental temperature, acquiring door opening information of a refrigerator compartment, and acquiring a corresponding door opening correction coefficient according to the door opening information; the door opening information comprises door opening compartments, door opening time and door opening times of the compartments in the current time period;
S2, calculating a refrigerator door opening weighted value in the current time period according to a preset weighted value calculation model according to the loop Wen Xiuzheng coefficient, the door opening correction coefficient, the door opening duration and the door opening times;
And S3, when the refrigerator door opening weighted value meets a preset abnormal door opening condition, the rotating speed of the refrigerator compressor is increased to a preset high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a preset limit interval duration.
Specifically, in step S1, the operation cycle of the refrigeration system includes two phases, namely a refrigeration phase and a defrosting phase, each phase having a corresponding operation duration. When the refrigerator is powered on, an environment temperature detection device arranged outside the refrigerator body is started to start to detect the environment temperature, the detected environment temperature is sent to the controller, and the controller simultaneously starts to detect door opening information of doors of all compartments in the refrigerator. The controller may detect door opening information of the refrigerator in a certain time period, for example, dividing 24 hours a day into 12 time periods, and then one time period occupies 2 hours, and the refrigerator counts door opening information within the 2 hours every 2 hours.
The ring Wen Xiuzheng coefficients are obtained by dividing a plurality of environment temperature ranges, different environment temperature ranges correspond to different ring temperature correction coefficients, the ring Wen Xiuzheng coefficients are in a direct proportion relation with the grades of the environment temperature ranges, and the grades of the environment temperature ranges are in a direct proportion relation with the environment temperature; for example, the environment temperature range includes two ranges, namely T is less than or equal to 25 ℃ and T is more than 25 ℃, the influence of the environment temperature on the opening of the refrigerator is smaller under the condition of lower temperature, so that the corresponding ring temperature correction coefficient is 1 under the condition of T is less than or equal to 25 ℃, otherwise, the influence of the environment temperature on the opening of the refrigerator is larger under the condition of higher temperature, and the corresponding ring temperature correction coefficient is 1.2 under the condition of T is more than 25 ℃. It should be noted that, the values of the ring temperature correction coefficients provided in the embodiment of the present invention are only examples, and in actual use, the environmental temperature range may be divided into more than 3 values, and the corresponding ring temperature correction coefficients may also be other values, which are not limited specifically herein.
The door opening correction coefficient is determined according to the type of the compartment of the refrigerator, different door opening correction coefficients correspond to different compartments, and the door opening correction coefficient and the refrigerating capacity of the compartment are in a proportional relation; different types of compartments have different influences caused by the door opening, and if the compartments with lower temperatures are opened more times, the compartments with higher influences on the temperature of the compartments are caused more, for example, the door opening correction coefficient corresponding to the refrigerating compartment is 1, and the door opening correction coefficient corresponding to the freezing compartment is 3. It should be noted that, the values of the door opening correction coefficients provided in the embodiments of the present invention are only examples, and in actual use, the types of the refrigerator compartments may include 3 or more than 3, for example, the refrigerator compartments further include a fresh-keeping compartment, and the corresponding door opening correction coefficients may also be other values, which are not limited specifically herein.
Specifically, in step S2, the weighted value calculation model satisfies the following formula:
Wherein P is a refrigerator door opening weighted value in the current time period; n is the number of compartments of the refrigerator; q i is the ring temperature correction coefficient corresponding to the ith chamber at the current ambient temperature; m i is the door opening correction coefficient corresponding to the ith chamber; t i is the average door opening time length when the door body of the ith compartment is opened; h i is the total number of times the door of the ith compartment is opened during the current time period. For example, after the door-open time length is obtained, an average door-open time length needs to be calculated, where the average door-open time length=total door-open time length/door-open times. And substituting the average door opening duration into the formula.
Specifically, in step S3, the abnormal door opening conditions include a severe door opening condition and an extreme door opening condition, the high rotation speed includes a first high rotation speed and a second high rotation speed, and the limit interval duration includes a first interval duration and a second interval duration; and increasing the rotation speed of the compressor to a preset high rotation speed in a preset time period, and shortening the defrosting interval of the refrigeration system in the current running period to a preset limit interval duration, wherein the method comprises the following steps of:
When the refrigerator door opening weighted value meets the severe door opening condition, the rotating speed of the compressor is increased to a first high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a first interval duration; when the refrigerator door opening weighted value meets the extreme door opening condition, the rotating speed of the compressor is increased to a second high rotating speed in a preset time period, and the defrosting interval of the refrigerating system in the current running period is shortened to a second interval duration; the second high rotating speed is larger than the first high rotating speed, and the second interval duration is smaller than the first interval duration.
Illustratively, the extreme door opening condition is that the refrigerator door opening weight is greater than a first fixed value, for example, the first fixed value is 600, that is, P > 600 is satisfied; the severe door opening condition is that the refrigerator door opening weighted value is between a first fixed value and a second fixed value, and the second fixed value is smaller than the first fixed value, for example, the second fixed value is 200, namely, the P is more than or equal to 200 and less than or equal to 600. The second high rotation speed is 4000 revolutions or more, the first high rotation speed is between [3000-4000 ], the second interval duration is 12h, and the first interval duration (unit: h) Between (12, 18). The higher the rotating speed of the compressor is, the higher the refrigerating efficiency is, and the more frosting quantity of the evaporator is caused, at the moment, the defrosting interval is required to be shortened to timely defrost, and the phenomenon that the normal refrigeration of the refrigerator is influenced due to the fact that the excessive frosting quantity on the evaporator is avoided.
Further, when the refrigerator does not satisfy the abnormal door opening condition, the refrigerator control method further includes:
when the refrigerator door opening weighted value meets a preset door closing condition, controlling the rotating speed of the compressor to be kept at a preset normal rotating speed, and controlling the defrosting interval of the refrigeration system in the current running period to be a preset normal interval duration;
When the refrigerator door opening weighted value meets a preset common door opening condition, controlling the rotating speed of the compressor to be kept at a preset target rotating speed, and controlling the defrosting interval of the refrigeration system in the current running period to be a preset target interval duration;
Wherein the target rotational speed is greater than the normal rotational speed, the target rotational speed being less than the high rotational speed; the target interval duration is smaller than the regular interval duration, and the target interval duration is longer than the limit interval duration; the abnormal door opening condition corresponds to the control logic with higher priority than the normal door opening condition, and the normal door opening condition corresponds to the control logic with higher priority than the door closing condition.
The normal door opening condition is that the door opening weighted value of the refrigerator is between a third fixed value and a second fixed value, and the third fixed value is smaller than the second fixed value, for example, the third fixed value is 80, namely, the condition that P is more than or equal to 80 and less than 200 is satisfied; and the door closing condition is that the door opening weighted value of the refrigerator is smaller than the third fixed value, namely P is smaller than 80. The target rotational speed is greater than the normal rotational speed, the target rotational speed is less than the high rotational speed, such as the target rotational speed having a value of [2000,3000 ], and the normal rotational speed is less than 2000 revolutions. The target interval duration is less than the regular interval duration, the target interval duration is greater than the limit interval duration, for example, the target interval duration (unit: h) has a value of [18,24 ], and the regular interval duration has a value of [24,30].
It should be noted that, the compressor rotation speed control corresponding to the normal door opening condition and the door closing condition may maintain a refrigeration stage, but only the compressor rotation speed corresponding to the abnormal door opening condition needs to maintain a preset time period (for example, 1 h), if the compressor is operated at a high rotation speed for a long time, the refrigerator is easy to be cooled too much, and the actual temperature of the compartment is further far less than the temperature set by the user, which may cause freezing of food in the refrigerating compartment, so after the compressor rotation speed is controlled to maintain at the preset rotation speed, the compressor rotation speed control corresponding to the normal door opening condition may be switched back, or the compressor rotation speed control corresponding to the door closing condition may also be switched back.
It is worth to be noted that, the abnormal door opening condition corresponds to the control logic with a higher priority than the normal door opening condition, and the normal door opening condition corresponds to the control logic with a higher priority than the door closing condition. Because the controller divides the running time period of the refrigerator in advance, if multiple door opening is detected in the current running time period and the refrigerator door opening weighted value meets the extreme door opening condition, the rotating speed of the compressor can be increased to a second high rotating speed, such as 4500 revolutions, in a preset time period (such as 1 h), and the defrosting interval of the current running period is controlled to be 12h in a second interval duration. If the refrigerator is in the defrosting stage, defrosting is stopped immediately and the refrigerator enters the refrigerating stage so as to make up the refrigerating capacity as soon as possible, at the moment, the compressor is started and maintains the rotating speed of 4500 revolutions in a preset time period (1 h), and the refrigerator is restored to the conventional rotating speed or the target rotating speed after 1 h; if the refrigerator is in the refrigeration stage and does not enter the defrosting stage, and the defrosting interval duration does not reach 12h, the rotating speed of the compressor is increased, and the defrosting interval duration of the defrosting stage to be entered next is set to be 12h; if the defrosting interval time reaches 12 hours, defrosting is immediately carried out after the rotation speed of the compressor is increased. If the abnormal door opening condition and the normal door opening condition are met at the same refrigeration stage, for example, the abnormal door opening condition is met in the first 2 hours and the normal door opening condition is met in the latter 2 hours, the corresponding control logic of the abnormal door opening condition is preferably executed at the moment, and after the control logic is executed, the control logic corresponding to the normal door opening condition is executed.
Compared with the prior art, the refrigerator control method disclosed by the embodiment of the invention has the advantages that whether the door opening times are too large is determined by monitoring the door opening times of a user, and the door opening times are too large, so that the temperature of a refrigerator compartment is too high to be beneficial to the storage of food materials, and therefore, when the door opening times are too large, the refrigerating capacity of the refrigerator compartment needs to be timely supplemented, and the compartment temperature is prevented from being too high for a long time. In addition, in the embodiment of the invention, the compressor and the defrosting period are not controlled only through the door opening times, the ring Wen Xiuzheng coefficient and the door opening correction coefficient are introduced, the influence of different environment temperatures on the door opening of the refrigerator is different, when the environment temperature is lower, the temperature of the air which is externally gushed in when the refrigerator is opened is not too high, at the same time, the influence on the compartments is smaller, meanwhile, the door opening correction coefficient is related to the types of the compartments of the refrigerator, the influence on the door opening of the compartments of different types is different, if the door opening times of the compartments with lower temperature are more, the influence on the temperature of the compartments is larger, the door opening weighting value of the refrigerator is calculated through the ring Wen Xiuzheng coefficient and the door opening correction coefficient, so that whether the door opening times of the refrigerator is too large or not is determined, the cold loss caused by the fact that a user opens the door for a plurality of times is timely made up, and the temperature rise of the indoor articles in a low temperature state is not influenced by the door opening is ensured.
