Specifically, a user can decide whether to start the energy-saving mode of the refrigerator according to personal requirements, and the operation convenience of energy-saving control of the refrigerator is improved. If the user does not turn on the energy saving mode, the energy saving mode does not interfere with the refrigerator control. When the energy-saving mode of the refrigerator needs to be started, a user inputs an energy-saving mode starting instruction to the control device through the interactive interface of the refrigerator, the control device starts the energy-saving mode of the refrigerator after receiving the energy-saving mode starting instruction, receives the use state data of the refrigerator collected by the data collecting device, and the use state data serve as the basis for the energy-saving operation subsequently.
Step S200: and determining a target energy saving level of the refrigerator according to the using state data.

In one embodiment, the control device determines a level adjustment amplitude according to the usage state data, and then determines a target energy saving level in combination with the level adjustment amplitude and the current energy saving level. For example, if the control device determines that one level of energy saving level needs to be lowered according to the use state data, and the current energy saving level of the refrigerator is level 2, the target energy saving level is level 1. The grade adjustment amplitude is directly determined according to the using state data, the target energy-saving grade is obtained by adjusting the current energy-saving grade of the refrigerator, the operation is simple, convenient and quick, the energy-saving adjustment operation is not required to be frequently carried out, and the electric energy is saved.

The manner of displaying the target energy saving level is not unique, and specifically, the energy saving mode icon may be set on the display interface of the refrigerator, and the control device controls the energy saving mode icon to display and light different patterns or characters according to the determined target energy saving level, so as to inform the user of the energy saving level of the refrigerator. It can be understood that if the user does not turn on the energy saving mode, the energy saving mode icon is not lit, and the energy saving mode does not interfere with the refrigerator control.
In one embodiment, the control device may specifically perform fine adjustment on the operation parameter corresponding to the current parameter gear according to the target energy saving level; or determining a target parameter gear according to the target energy-saving level and adjusting the operation parameters of the refrigerator according to the target parameter gear. Specifically, the control device may pre-establish a corresponding relationship between the energy saving level and the operation parameter, and directly set the refrigerator to the corresponding operation parameter according to the determined target energy saving level. In addition, the control device may also divide the operation parameters into different levels of gears in advance, and establish the corresponding relationship between the energy saving level and the parameter gear. The control device finds a target parameter gear according to the determined target energy-saving level to carry out parameter adjustment; or finding a gear adjusting amplitude according to the determined target energy-saving level, and determining a target parameter gear by combining the gear adjusting amplitude and the current parameter gear of the refrigerator to perform parameter adjustment.
The two energy-saving optimization modes of gear adjustment or gear parameter fine adjustment are provided, and it can be understood that the control device can also be used for performing energy-saving control on the refrigerator by simultaneously combining gear adjustment and gear parameter fine adjustment, and the accuracy of the energy-saving control can be improved.

The energy-saving level of the refrigerator can be adjusted in time according to the actual using state of the refrigerator, unnecessary energy consumption is avoided, and compared with the traditional refrigerator, the energy-saving refrigerator can reduce the power consumption of the refrigerator and save electric energy.
In one embodiment, the use state data includes door opening data of the refrigerator. As shown in fig. 2, step S200 includes steps S210 to S240.
Step S210: and if the door opening data of the refrigerator meets the preset grade improvement condition, improving the energy-saving grade of the refrigerator by one grade to obtain the target energy-saving grade.
Step S220: and if the door opening data of the refrigerator accords with a preset grade maintaining condition, maintaining the energy-saving grade of the refrigerator unchanged to obtain the target energy-saving grade.

The grade-up conditions include: the door opening times in the preset unit time are zero; or the rank-up condition includes: the door opening times in the preset unit time reach a first preset time, and the state that the door opening time is less than or equal to the first preset time lasts for a preset duration. The control device monitors and analyzes the door opening times and the door opening time of the refrigerator in preset unit time, and when the door opening times and the door opening time in the preset unit time meet any one of two grade improving conditions, the energy-saving grade of the refrigerator is improved by one grade to obtain a target energy-saving grade.
Further, in one embodiment, the rank maintenance condition includes: the door opening times in the preset unit time reach a second preset time; or the grade maintenance conditions include: the door opening time in the preset unit time is greater than the first preset time and is less than or equal to the second preset time; the second preset time is greater than the first preset time, and the second preset time is greater than the first preset time. When the control device analyzes that the door opening times and the door opening time in the preset unit time meet any one of two grade maintaining conditions, the energy-saving grade of the refrigerator is kept unchanged, and the target energy-saving grade is obtained.
In one embodiment, the rank-down condition includes: the door opening times in the preset unit time reach a third preset time; or the gradation lowering conditions include: the door opening time in the preset unit time is greater than the second preset time and is less than or equal to the third preset time; the third preset time is greater than the second preset time, and the third preset time is greater than the second preset time. When the control device analyzes that the door opening times and the door opening time in the preset unit time meet any one of two grade reduction conditions, the energy-saving grade of the refrigerator is reduced by one grade, and the target energy-saving grade is obtained.
In one embodiment, the level clear condition includes: the door opening times in the preset unit time are more than a third preset time; or the level clear condition includes: the door opening time in the preset unit time is greater than the third preset time. When the control device analyzes that the door opening times and the door opening time in the preset unit time meet any one of two equal-grade zero clearing conditions, the energy-saving grade of the refrigerator is cleared, namely the target energy-saving grade is zero grade.
Specifically, specific values of the preset unit time, the first preset number of times, the first preset time, the preset duration, the second preset number of times, the second preset time, the third preset number of times, and the third preset time are not unique, and a user can adjust the values according to actual conditions. In this embodiment, the preset unit time is 1 hour, the first preset number of times is 1 time, the first preset time is 10 seconds, the preset duration is 2 hours, the second preset number of times is 2 times, the second preset time is 30 seconds, the third preset number of times is 3 times, and the third preset time is 1 minute.
In another embodiment, the usage state data includes a single turn-on time of a compressor of the refrigerator. As shown in fig. 3, step S200 includes steps S250 to S280.
Step S250: and if the times that the single starting time of the compressor is less than or equal to the first set time reach the set times, improving the energy-saving grade of the refrigerator by one grade to obtain the target energy-saving grade.
Step S260: and if the single starting time of the compressor is longer than the first set time and is shorter than or equal to the second set time, maintaining the energy-saving grade of the refrigerator unchanged to obtain the target energy-saving grade.
Step S270: and if the single starting time of the compressor is longer than the second set time and shorter than or equal to the third set time, reducing the energy-saving grade of the refrigerator by one grade to obtain a target energy-saving grade.
Step S280: and if the single starting time of the compressor is more than the third set time, resetting the energy-saving grade of the refrigerator to obtain the target energy-saving grade.
Specifically, the values of the first set time, the set times, the second set time, and the third set time are not unique. In one embodiment, the first set time is 30 minutes, the set number of times is 3, the second set time is 1 hour, and the third set time is 3 hours. According to the single starting time of the compressor of the refrigerator, the control device can also determine the corresponding target energy-saving grade, and the operation is simple, convenient and reliable.
It will be appreciated that in one embodiment, the usage status data may also include both door open data for the refrigerator and a single compressor on time. For example, when the control device determines that the energy saving level needs to be increased by one step according to the door opening data of the refrigerator and also determines that the energy saving level needs to be increased by one step according to the single starting time of the compressor, the current energy saving level of the refrigerator is increased by two steps to obtain the target energy saving level. And when the control device determines that the energy-saving grade needs to be increased by one grade according to the door opening data of the refrigerator and also determines that the energy-saving grade needs to be decreased by one grade according to the single starting time of the compressor, keeping the current energy-saving grade of the refrigerator unchanged as the target energy-saving grade. Meanwhile, the target energy-saving grade of the refrigerator is determined by combining the door opening data of the refrigerator and the single starting time of the compressor, so that the comprehensiveness and the accuracy of energy-saving control can be improved.
According to the different number of the energy-saving grades, the specific mode for performing energy-saving control on the refrigerator according to the target energy-saving grade is correspondingly different. Taking the example that the energy saving grade comprises four grades, namely zero grade, first grade, second grade and third grade. In one embodiment, as shown in fig. 4, the energy saving control of the refrigerator according to the target energy saving level in step S300 includes steps S310 to S340.
Step S310: and if the target energy-saving level is zero level, reducing the current refrigerating and freezing set gear temperature of the refrigerator, and increasing the starting frequency level of the compressor. Specifically, when the target energy saving level is zero level, the control device finely adjusts the temperature of the current refrigeration and freezing set gear, for example, by 1 ℃. In addition, the compressor turn-on frequency is increased by one step.
Step S320: and if the target energy-saving grade is one grade, keeping the current state of the refrigerator unchanged. When the target energy-saving level is one level, the refrigerator normally runs, the energy-saving mode does not interfere with the control of the refrigerator, and the current state of the refrigerator is kept unchanged.
Step S330: and if the target energy-saving grade is two-grade, reducing the refrigeration set gear grade of the refrigerator, and increasing the first set time of the defrosting interval. If the target energy-saving level is two, the control device reduces the refrigeration set gear by one level, and specifically, the defrosting interval can be increased by 5 hours.
Step S340: and if the target energy-saving level is three levels, reducing the refrigeration and freezing set gear level of the refrigerator, controlling the compressor to run at the lowest gear, and increasing the second set time of the defrosting interval. Wherein the second set time is greater than the first set time. If the target energy-saving level is three levels, the control device reduces the refrigeration and freezing set gear by one level respectively, controls the compressor to operate at the lowest gear, and particularly can increase the defrosting interval by 24 hours.
It can be understood that the specific operating parameters of the refrigeration and freezing and the compressor at different gears are not unique and can be adjusted according to actual requirements. In the embodiment, different gears are established for the running parameters of refrigeration and freezing and the compressor, gear adjustment is carried out according to the target energy-saving level, and the gear parameter fine adjustment and defrosting interval adjustment are combined, so that the energy-saving control is more accurate and reliable.

If the single-time starting time of the compressor is longer than the first set time and shorter than or equal to the second set time, the level determination module 200 keeps the energy-saving level of the refrigerator to be improved unchanged, and a target energy-saving level is obtained. If the single-time starting time of the compressor is longer than the second set time and shorter than or equal to the third set time, the level determination module 200 decreases the energy-saving level of the refrigerator by one level to obtain the target energy-saving level. If the single-time starting time of the compressor is longer than the third set time, the grade determination module 200 clears the energy-saving grade of the refrigerator to obtain the target energy-saving grade.

In order to better understand the above method, device and refrigerator for controlling energy saving of refrigerator, the following detailed explanation is made in conjunction with specific embodiments.
According to the energy-saving control method of the refrigerator, according to the using condition of a user, when the user uses the refrigerator less or does not use the refrigerator, the gear of the refrigerator is automatically reduced, the power consumption of the refrigerator is reduced, and the user is helped to save electric energy. In order to enable a user to use the refrigerator more in an energy-saving and environment-friendly manner, the energy-saving grade of the refrigerator is displayed on the refrigerator. Through the grade conversion of intelligence and judge, divide into a plurality of grades with energy-conservation, different grades correspond different refrigerator gears and adjust, and is more intelligent careful. The energy-saving level of the refrigerator is intelligently analyzed by collecting the using habits of the refrigerator of the user. The energy-saving level reduces the gear of the refrigerator and reduces the energy consumption of the refrigerator.
As shown in fig. 6, which is a schematic flow chart of energy saving control of a refrigerator, a user determines whether to start an energy saving mode according to personal needs, an energy saving level is displayed on a display panel, and the user cannot adjust the energy saving level. After the energy-saving mode is started, the internal program of the refrigerator can collect the number of times of opening the door in each hour, and the compressor is started for a single time. If the door is opened for zero times in one hour, the energy-saving grade is improved by one grade. If the door is opened once in one hour and the door opening time is less than 10 seconds, the energy-saving grade is improved by one level in the state of two continuous hours. If the door is opened twice in one hour, or the door opening time is 10 seconds to 30 seconds, the grade is not changed. And if the door is opened three times in one hour or the door opening time exceeds 30 seconds and is less than one minute, the energy-saving grade is reduced by one grade. And if the door is opened for more than three times in one hour or the door opening time exceeds one minute, directly resetting the energy-saving grade. If the single time of the compressor is less than 30 minutes, the compressor is kept for three times. The energy-saving grade is improved by one grade, the starting time of the compressor is 30 minutes to 1 hour, and the energy-saving grade is unchanged. And if the single-time opening time of the compressor is 1 hour to 3 hours, reducing the first-level energy-saving grade, and if the single-time opening time of the compressor exceeds 3 hours, resetting the energy-saving grade.
The energy-saving grade is divided into four grades, namely zero grade, first grade, second grade and third grade. At zero level, the refrigerator is in a high load state, the system can reduce the current refrigeration and freezing set gear by 1 ℃, and the starting frequency of the compressor is increased by one level. In the first stage, the refrigerator is in normal operation, and the ECO (energy saving mode) does not interfere with the control of the refrigerator. And in two stages, the refrigeration set gear is reduced by one stage, and the defrosting interval is increased by 5 hours. And in the third stage, the refrigeration and freezing set gear is respectively reduced by one stage, the compressor is operated at the lowest gear, and the defrosting interval is increased by 24 hours. The highest grade is three, and the lowest grade is zero.
The user does not turn on the energy saving mode, and the energy saving mode icon is not lighted and does not interfere with the refrigerator control. As shown in fig. 7, which is a schematic diagram of an energy saving mode icon, after a user starts the energy saving mode, the icon is lighted, and corresponding characters in the icon are controlled to be lighted according to the energy saving mode of the refrigerator, so that the user can conveniently view the icon.
