Detailed Description
Fig. 1 is a schematic block diagram of control components of a refrigerator 100 according to one embodiment of the present invention. The refrigeration system 200 of the refrigerator 100 of the present example can be controlled to provide cooling energy to the interior, ensuring that the temperature inside the refrigerator 100 fluctuates above and below a target temperature, and maintaining a good storage environment. The refrigerator may be a direct-cooling refrigerator or an air-cooling refrigerator, and the refrigeration system is started to cool the inside when the temperature exceeds the start-up threshold, and the refrigeration system 200 is turned off after the temperature reaches the expected temperature. The refrigerator 100 of the embodiment improves the scheme of refrigeration control, reduces the influence of refrigerator operation on user use, and improves refrigeration efficiency.
The refrigerator 100 of the present embodiment may generally include: the refrigeration system 200 and the refrigeration controller 300 include a memory 310 and a processor 320, wherein the memory 310 stores a control program 311, and the control program 311 is executed by the processor 320 to implement the control method of the refrigerator 100 according to the present embodiment.
The refrigerator 100 of the present embodiment may further have a timer 220, a temperature sensor 210, and a door opening detector 230. The timer 220 may employ various timing devices for accurately determining time, and in some embodiments, the timer 220 may have a network time setting function to ensure accurate time setting. The temperature sensor 210 is disposed inside the refrigerator to measure an internal temperature of the refrigerator.
The door opening detector 230 may use a hall switch, a contact switch, or the like to detect the opening and closing operation of the door. After the door body is opened, corresponding indication signals can be output.
The refrigeration system 200 may be a refrigeration cycle system constituted by a compressor, a condenser, a throttle device, an evaporator, and the like. The evaporator serves as a cooling source to supply cooling energy to the inside of the refrigerator 100. The compressor is used as the power of the refrigeration cycle to extract the vapor in the evaporator, and the pressure and the temperature of the refrigerant vapor are improved through the compression action, so that the condition of transferring the heat of the refrigerant vapor to the external environment medium is created. In other embodiments, other principles of refrigeration systems, such as semiconductor refrigeration systems, may be used in the art.
Since the structure of the refrigerator 100 and the refrigeration system 200 are well known and easily implemented by those skilled in the art, the structure of the refrigerator 100 and the refrigeration system 200 will not be described in detail in order to avoid obscuring and obscuring the invention of the present application.
Fig. 2 is a schematic diagram of a control method of the refrigerator 100 according to one embodiment of the present invention, the control method of the refrigerator 100 generally including:
step S202 is to obtain a refrigeration operation schedule of the refrigerator 100, where a plurality of operation periods and corresponding refrigeration control strategies are defined in the refrigeration operation schedule. The operational period may include: a no-cool period, a regular cool period, and a priority cool period.
The refrigeration control strategy corresponding to the refrigeration forbidding time period comprises the following steps: the refrigeration system 200 of the refrigerator 100 is prohibited from starting. The cooling prohibition period may be a period in which the user is expected to use the refrigerator 100, that is, in the cooling prohibition period, the refrigeration system 200 of the refrigerator 100 is prohibited from being activated in order to reduce noise interference and cooling loss to the user due to cooling.
The refrigeration control strategy corresponding to the conventional refrigeration period comprises the following steps: the refrigeration system 200 is started when the refrigerating temperature of the refrigerator 100 is higher than the preset startup point temperature, and the refrigeration system 200 is turned off when the refrigerating temperature is lower than the preset shutdown point temperature. The normal cooling period may be a normal state of operation of the refrigerator 100, which takes a majority of the time.
The refrigeration control strategy corresponding to the priority refrigeration period comprises the following steps: the refrigeration system 200 is started when the refrigeration temperature of the refrigerator 100 is above a priority start-up threshold, and the refrigeration system 200 is shut down when the refrigeration temperature is below a delayed shut-down threshold, where the priority start-up threshold is below a start-up point temperature and the delayed shut-down threshold is below a shut-down point temperature. The preferential cooling period is generally a period before the cooling prohibition period, and in order to ensure that the storage temperature inside the refrigerator 100 can be maintained even when the refrigeration system 200 is not activated during the cooling prohibition period. During the preferential cooling period, the temperature is lowered to a lower level in advance.
In some embodiments, the power-on point temperature and the power-off point temperature are set according to a target temperature of the refrigerator 100, respectively. Therefore, the temperature of the shutdown point and the temperature of the startup point are dynamically adjusted according to the target temperature, so that the deviation between the temperature of the compartment and the target temperature is smaller, and the storage requirement is met.
The preferential power-on threshold is set to the power-on point temperature minus a preset first redundant temperature value (a fixed value, e.g., 2 ℃), and the delayed power-off threshold is set to the power-on point temperature minus a preset second redundant temperature value (another fixed value, e.g., 1 ℃).
For example, the target temperature may be set to-15 deg.C, the power-on point temperature may be set to-14 deg.C, and the power-off point temperature may be set to-18 deg.C. That is, in the normal cooling period, the cooling system 200 starts cooling when the internal temperature of the refrigerator 100 reaches-14 c, and the cooling system 200 is turned off when the internal temperature of the refrigerator 100 is lowered to-18 c. Accordingly, the priority power-on threshold may be set to-20 deg.C, while the delayed power-off threshold may be set to-13 deg.C. Thus, in the priority cooling stage, the temperature inside the refrigerator 100 is lower, ensuring that the temperature can be kept stable in the cooling prohibition period thereafter.
Step S204 obtains the operation time of the refrigerator 100, and determines the operation time period to which the operation time belongs. The refrigerator 100 may obtain the time through the timer 220, and in other embodiments, the time may also obtain the network time.
Step S206 performs cooling control on the refrigerator 100 according to the cooling control strategy corresponding to the operation time period to which the operation time belongs.
The above-described cooling operation schedule may be based on usage record information of the refrigerator 100, the usage record information including: the time of door opening of the refrigerator 100 and the duration of each door opening.
The step of generating the cooling operation schedule based on the usage record information of the refrigerator 100, for example, includes: dividing a use cycle of the refrigerator 100 into a plurality of statistical time periods; respectively carrying out probability calculation on the door opening time of the refrigerator 100 in each statistical time period and the duration time of each door opening to obtain the expected door opening time and the expected door opening duration time in each statistical time period; setting a refrigeration forbidding period according to the expected door opening time and the expected door opening duration; setting a time period of a set time length before the refrigeration forbidding time period as a priority refrigeration time period; and setting the period except the refrigeration forbidding period and the priority refrigeration period in each statistical period as the regular refrigeration period.
The usage period of the refrigerator 100 may be a whole day and a week, and may be counted by day. For example, the above statistical period may be divided into: daytime and nighttime periods; or divided into: morning hours, noon hours, afternoon hours, night hours. One specific division manner may be: 0:00-10:00, 10:00-15:00, 15:00-0: 00. Because the modes of using the refrigerator 100 by the user are different in different statistical time periods, the usage cycle of one refrigerator 100 is respectively counted according to the statistical time periods in the embodiment, so that the usage habits of the user at different times can be better met, and the operation schedule can be more accurately formulated.
The step of calculating the probability of the door opening time and the duration of each door opening of the refrigerator 100 for each statistical period of time includes: extracting door opening records in each statistical time interval; establishing respective refrigerator door opening prediction models in each statistical time interval according to the door opening records; and respectively carrying out probability calculation by utilizing the refrigerator door opening prediction model of each statistical time interval.
The control method comprises the following steps: acquiring a door opening and closing trigger signal of the refrigerator 100; and updating the door opening record according to the door opening and closing trigger signal. For example, after each door opening of the refrigerator 100, the door opening time of the refrigerator 100 may be recorded, and after the door closing of the refrigerator 100, the door closing time of the refrigerator 100 may be recorded, so that the parallel door opening duration may be determined to form a one-time door opening record. The door opening record is updated in real time according to the use condition of the user, so that the refrigerator door opening prediction model is more in line with the use habit of the user.
For example, by performing model training on the door opening records during the period of 15:00-0:00, and the refrigerator door opening prediction model estimates that the probability of 2 minutes of door opening at 18:00 and 5 minutes of door opening at 19:30 is the greatest, then the time period of 17:50 to 18:12, and the time period of 19:20 to 19:45 may be set as the refrigeration inhibited period during which the refrigerator refrigeration system 200 is inhibited from starting. The time periods of 30 minutes before 17:50 and 19:20, that is, 17:20 to 17:50, 18:50 to 19:20 are set as preferential cooling periods during which the refrigerator 100 is caused to enter cooling at a temperature lower than the power-on point temperature and is caused to stop at a temperature lower than the power-off point temperature. During the time period of 15:00-0:00, except for 17: 50-18: 12, 19: 20-19: 45, 17: 20-17: 50, 18: 50-19: 20, the refrigeration is carried out according to the normal starting point temperature and the normal shutdown point temperature.
The flow of generating the cooling operation schedule for other statistical periods of the usage cycle of the refrigerator 100 can be easily derived by those skilled in the art through the above-mentioned examples of the period of 15:00-0: 00.
In the embodiment of the present invention, the processes of setting the cooling prohibition time period, the cooling priority time period, and the normal cooling time period may be performed by a main control board of the refrigerator 100, or may be performed by a network side device. For example, the refrigerator 100 uploads the door opening and closing signals through the internet, the network server generates door opening and closing records, and a refrigerator door opening prediction model is built.
Another step of generating the cooling operation schedule based on the usage record information of the refrigerator 100 may be: setting a statistical time interval in which the door opening times exceed a first set value as a refrigeration forbidding time interval; setting a time period of a set time length before the refrigeration forbidding time period as a priority refrigeration time period; the period other than the prohibition cooling period and the priority cooling period in the use cycle of the refrigerator 100 is set as the regular cooling period.
Also taking the time period of 15:00-0:00 as an example, in this embodiment, if the number of times the door of the refrigerator 100 is opened is significantly higher between 18:00 and 18:20, and 19:20 and 19:40 than in other time periods, 18:00 to 18:20, and 19:20 to 19:40 are set as the cooling prohibition time period in which the refrigerator cooling system 200 is prohibited from being started. The time periods of 30 minutes before 18:00 and 19:20, that is, 17:30 to 18:00, 18:50 to 19:20 are set as the priority cooling periods in which the refrigerator 100 is caused to enter cooling at a temperature lower than the temperature at the turn-on point and the temperature is stopped at a temperature lower than the temperature at the turn-off point. And in other time periods, the refrigeration is still carried out according to the normal starting point temperature and the normal shutdown point temperature.
Another step of generating the cooling operation schedule based on the usage record information of the refrigerator 100 may be: and averaging the door opening time and the door opening duration in each statistical time period, and setting a refrigeration forbidding period according to the average value.
For example, the door opening time t and the door opening duration Δ t are respectively recorded in three time periods of each day, wherein the three time periods are respectively 0:00 to 10:00, 10:00 to 3:00 and 3:00 to 0: 00; and averaging the door opening time and the duration time of each time period, and performing statistics calculation again to average the door opening time and the duration time every time when the door is opened so as to obtain a more accurate use habit. According to the latest door opening time and the latest duration, the set time T-delta T-T (T is a preset time length value) before the average door opening time is started, the refrigeration is finished in advance, and the refrigeration is not performed in the time period of T plus delta T plus T, so that the noise value of a user during the possible use period is reduced, and the user experience is improved. Judging the relation between the internal temperature of the refrigerator 100 and the switch temperature value at the time 2T before the time T; if the refrigerator 100 is refrigerating, the refrigeration is continued, and the refrigeration is stopped when the shutdown temperature value is reduced by 1 degree; if the difference value between the internal temperature of the refrigerator and the starting temperature value is less than N, starting refrigeration until the starting temperature value is reduced by 1 degree or T time is up; and if the difference value of the internal temperature of the refrigerator and the starting temperature value is larger than N, refrigerating is not carried out until T +. DELTA.t + T time, and then normal control is carried out.
