Detailed Description
In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the following detailed description of the embodiments of the present invention refers to the accompanying drawings.
Referring to fig. 1, a flowchart of a control method of a refrigeration appliance according to an embodiment of the present invention is provided. The method specifically comprises the following steps:
and step 11, when the distance from the current cooling capacity to the refrigerating appliance is detected to be the first duration, respectively calculating whether the current cooling capacity in each storage compartment of the refrigerating appliance meets the corresponding reserved cooling capacity according to the temperature rise rates respectively corresponding to the storage compartments of the refrigerating appliance.
In particular implementations, the refrigeration appliance may include a refrigerator, freezer, or the like having a refrigeration function. A plurality of storage compartments may be provided in the refrigerator, and the temperature in each storage compartment may be different. The rate of temperature rise for each compartment can be calculated as follows:
when the compressor of the refrigeration appliance is stopped, the temperature of each storage compartment of each set time node in a preset time period is obtained. And calculating the temperature rise rate corresponding to each storage compartment according to the temperature corresponding to each time node of each storage compartment in the preset time period.
For example, the refrigerator includes three storage compartments, a refrigerating compartment, a temperature varying compartment, and a freezing compartment, respectively. Taking one day as an example, 24 hours are divided into 48 nodes in half an hour, the temperatures of the refrigerating chamber, the temperature changing chamber and the freezing chamber, which are respectively corresponding to the 48 nodes, are recorded, and the temperature rising rates of the refrigerating chamber, the temperature changing chamber and the freezing chamber, which are respectively corresponding to the refrigerating chamber, the temperature changing chamber and the freezing chamber, within the 24 hours are obtained.
In order to improve the accuracy of the obtained temperature rise rate, in the embodiment of the invention, the temperature rise rate of preset days can be continuously counted, and the average value of the temperature rise rates of the preset days is used as the temperature rise rate of the refrigerator. The calculated rate of temperature rise may be stored in a non-volatile memory of the refrigeration appliance to ensure loss of power.
In implementations, the rate of temperature rise of the refrigeration appliance may be affected by a variety of factors, such as ambient temperature, the number of items in the storage compartment, etc., and thus, the rate of temperature rise of the refrigeration appliance may be periodically calculated and updated.
In a specific implementation, the opening and closing states and opening and closing time points of the doors of the storage compartments of the refrigeration appliance are monitored, and the use habit of a user on the refrigeration appliance can be determined according to the opening and closing states, the opening and closing time points and the temperature rise rate of each storage time.
In one embodiment of the invention, the period of silence may be determined based on the usage habits of the user with respect to the refrigerator. For example, the user opening and closing the doors of each compartment is mainly focused on between 7:00 and 22:00 a day, while at 22: the door of the refrigerator was not opened between 00 and 7:00 of the next day, from which it can be inferred that at 22: the probability that the period from 00 to 7:00 of the next day is a rest period of the user is large, and in order to reduce the influence of noise generated when the refrigerating appliance is used for refrigerating on the rest of the user, 22: all or part of the period of 00 to 7:00 of the next day is set as the mute period. Usually, the rest time of the user is mainly concentrated between 20:00 a night and 8:00 a day after the next day, and some users work at night and rest in daytime, so that the mute periods set by different users are different, and the mute periods are specifically set according to the use habit of the users on the refrigerating appliance.
In another embodiment of the present invention, a mute period setting instruction may be received, and the mute period may be determined according to the received mute period setting instruction, that is, the user may set the mute period according to his/her actual needs.
In a specific implementation, considering that the work and rest times corresponding to the user on the working day and the rest day may be different, the silence period may be divided into a silence period corresponding to the working day and/or a silence period corresponding to the rest day. The working day may refer to the working day in a legal sense, and may refer to the actual working time of the user. The holiday may refer to the legal holiday of the country, or the rest time when the user does not work.
In a specific implementation, when the detection distance enters the mute period of the refrigeration appliance to be the first time length, whether the current refrigeration capacity in each storage compartment of the refrigeration appliance meets the corresponding reserved refrigeration capacity can be calculated according to the temperature rise rates corresponding to the storage compartments of the refrigeration appliance respectively.
Specifically, the current temperature in each storage room is obtained, the temperature in each storage room is calculated when entering the mute period according to the temperature rise rate corresponding to each storage room and the current temperature corresponding to each storage room, when entering the mute period, whether the temperature in each storage room meets the corresponding preset temperature is judged, and when the temperature in any storage room does not meet the corresponding preset temperature, the current cold quantity is judged not to meet the corresponding reserved cold quantity; and when the temperatures in the storage compartments meet the corresponding preset temperatures, judging that the current cold quantity meets the corresponding reserved cold quantity.
And step 12, when the current cooling capacity in the ith storage compartment is detected to not meet the corresponding reserved cooling capacity, calculating the precooling time of the ith storage compartment according to the temperature drop rate of the ith storage compartment.
In practice, the rate of temperature drop for each compartment may be calculated as follows: and when the compressor works, recording the temperature drop time required by the current temperature in each storage compartment to be reduced to the preset temperature corresponding to each storage compartment, and calculating the temperature drop rate corresponding to each storage compartment according to the difference value between the current temperature in each storage compartment and the preset temperature corresponding to each storage compartment and the temperature drop time corresponding to each storage compartment. Depending on the function of each compartment, the corresponding rate of temperature drop may be different, e.g., the rate of temperature drop for a refrigerator compartment may be different from the rate of temperature drop for a freezer compartment.
In particular implementations, the calculated temperature drop rate may be stored in a non-volatile memory of the refrigeration appliance to ensure loss of power.
In the embodiment of the invention, when the current cold quantity in the ith storage compartment is detected to not meet the corresponding reserved cold quantity, the precooling time of the ith storage compartment is calculated according to the temperature drop rate of the ith storage compartment, wherein i is more than or equal to 1 and less than or equal to N, and N is the total number of the storage compartments of the refrigeration appliance. Specifically, the current temperature in each storage compartment may be obtained, and when the current temperature does not satisfy the preset temperature, it may be determined that the current cooling capacity does not satisfy the preset cooling capacity. According to the current temperature and the temperature drop rate in each storage compartment, the time length required for reducing the current temperature to the preset temperature can be calculated, so that the precooling time of each storage compartment is calculated by combining the starting time of the mute time period. For example, it takes 30 minutes to decrease from the current temperature to the preset temperature, and the start time of the mute period is 22:00, and the precooling time is 21:30. For another example, 30 minutes are required to reduce the current temperature to the preset temperature, the starting time of the mute period is 22:00, the pre-cooling time is 21:20, and pre-cooling is performed in advance, so that the temperature in each storage room can reach the preset temperature when the mute period is started.
When the pre-cooling time corresponding to each storage compartment of the refrigerator is different, the pre-cooling time far away from the mute time period can be used as the mute time to ensure that all the storage compartments can reduce the temperature to the preset temperature so as to ensure sufficient cold energy.
In a specific implementation, since the set temperatures of the storage compartments of different functions are different, the corresponding preset temperatures are correspondingly different. For example, the preset temperature of the storage compartment may be less than 2 ℃ than the set temperature. When the set temperature of the storage room for refrigeration is 2-5 ℃, the corresponding preset temperature is 0-3 ℃. The set temperature of the storage compartment for freezing is-18 ℃ to-5 ℃, and the corresponding preset temperature is-16 ℃ to-3 ℃. It can be understood that the preset temperature of each storage compartment is set correspondingly according to different factors such as actual requirements, actual application scenes, types of the refrigerating appliance, types of the storage compartments and the like, and specific values of the preset temperature are not limited.
And 13, when the pre-cooling time is reached, controlling the compressor of the refrigeration appliance to work so as to start refrigeration.
In a specific implementation, when the pre-cooling time is reached, the compressor of the refrigeration appliance can be controlled to start to work so as to perform refrigeration. If the compressor is already working according to the normal refrigeration program when the precooling time is reached, the compressor can be kept working continuously to ensure that the reserved cold is sufficient after entering the mute period. In the mute period, when the reserved cooling capacity is sufficient, even if the compressor is stopped, the temperature in each storage room after the temperature rise is still within the set proper temperature range.
And 14, controlling the compressor to stop when the current moment is detected to be in a mute period.
In a specific implementation, the compressor is controlled to stop when the detected current moment is in the mute period, i.e. in the mute period.
According to the scheme, when the mute time interval from entering the refrigerating appliance is detected to be the first time length, whether the current cooling capacity in each storage compartment of the refrigerating appliance meets the reserved cooling capacity is judged, and when the reserved cooling capacity is not met, the refrigerating is performed in advance, so that after entering the mute time interval and the compressor is stopped, the cooling capacity in each storage compartment of the refrigerating appliance can still be sufficient, and the actual requirements are met. The mute time period can be set according to the rest time of the user, and noise can not be generated because the compressor is stopped in the mute time period, so that the influence of refrigerator noise on the user at night or during the rest time of the user can be solved, and the user experience is improved.
In practice, as the compressor is shut down during the silent period, the temperature in each compartment will gradually rise at a corresponding rate of temperature rise. Generally, the temperature after rising is still within the set proper temperature range throughout the mute period, but in view of the influence of factors such as the duration of the mute period, the amount of food stored in the refrigerator, the opening and closing of the refrigerator during the mute period, the ambient temperature to which the refrigerator is exposed, etc., there may be a case where the temperature rises beyond the set proper temperature range. If the degree of temperature rise is high, the effect on food stored in the refrigerator is possibly caused, and in order to achieve the effect of noise and maintain the temperature in each storage compartment, in the embodiment of the invention, when the temperature in the j-th storage compartment for non-freezing is detected to be higher than the set first threshold value, the cold energy distribution fan is controlled to be started so as to send the cold energy in at least one storage compartment for freezing to the j-th storage compartment, wherein j is not less than 1 and not more than M, and M is the total number of the storage compartments for non-freezing in the refrigerator. Since the temperature in the storage compartments for freezing is generally low, as long as the temperature is maintained below 0 ℃, the influence on the preservation of food is small, so that the cold in the storage compartments for freezing is conveyed into the non-freezing storage compartments, the temperature of each storage compartment can be balanced, and the compressor is not required to be turned on, so that the influence of noise on the rest of a user is avoided.
In a specific implementation, the first threshold value corresponding to the non-frozen compartment may be set according to the type of compartment, and the first threshold value corresponding to different compartments may be different. For example, the first threshold corresponding to the refrigerating chamber may be 2 ℃ higher than the set temperature, and when the set temperature is 2 ℃, the first threshold is 4 ℃. The first threshold corresponding to the variable temperature chamber may be 2 ℃ higher than the set temperature, and when the set temperature is 0 ℃, the first threshold is 2 ℃. It is understood that the first threshold value corresponding to each storage compartment may be set according to the type of the storage compartment and the actual application requirement.
In a specific implementation, when the refrigerator is in the mute period, if the temperature in the storage room for freezing is detected to be higher than a set second threshold value, the compressor is controlled to be started, and the rotating speed of the compressor is controlled to be in a preset rotating speed range. The rotation speed of the compressor is controlled within a preset rotation speed range, for example, below 2000rpm, so that the temperature in the storage room for freezing can be controlled without generating large noise to influence the rest of a user.
For example, the corresponding second threshold value for the freezer compartment may be 4 ℃ above the set temperature, and when the set temperature is-18 ℃, the first threshold value is-14 ℃.
In a specific implementation, for some frostless refrigerators, a defrosting operation needs to be performed periodically, and when the defrosting time of the refrigerator is detected to be in the mute period, the defrosting time is adjusted to be before or after the mute period. Thereby avoiding noise caused by high-speed operation of the compressor during defrosting.
In the practice of the invention, the compressor is controlled to start or stop based on the actual temperature in each storage compartment after the end of the mute period is detected.
In order to facilitate better understanding and implementation of the present invention by those skilled in the art, the embodiment of the present invention further provides a control device for a refrigeration appliance.
