Detailed Description
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flow chart of a control method of a refrigeration appliance according to an embodiment of the present invention is shown. The method specifically comprises the following steps:
and 11, when the mute time interval of the refrigerating appliance is detected to be the first time interval, respectively calculating whether the current cold quantity in each storage room meets the corresponding reserved cold quantity according to the temperature rise rate respectively corresponding to each storage room 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 refrigeration appliance, and the temperature within each storage compartment may be different. The rate of temperature rise of each storage compartment can be calculated as follows:
when the compressor of the refrigeration appliance is stopped, the temperature of each storage compartment at each set time node in a preset time period is acquired. And calculating the temperature rise rate corresponding to each storage room according to the temperature corresponding to each time node of each storage room in a preset time period.
For example, a refrigeration appliance includes three storage compartments, a refrigerating compartment, a warming compartment, and a freezing compartment. Taking one day as an example, dividing 24 hours into 48 nodes in half an hour on average, recording the temperatures of the refrigerating chamber, the temperature-changing chamber and the freezing chamber corresponding to the 48 nodes respectively, and obtaining the temperature rise rates of the refrigerating chamber, the temperature-changing chamber and the freezing chamber corresponding to the refrigerating chamber, the temperature-changing chamber and the freezing chamber in the 24 hours respectively.
In order to improve the accuracy of the obtained temperature rise rate, in the embodiment of the invention, the temperature rise rates of preset days can be continuously counted, and the average value of the temperature rise rates of the preset days is taken as the temperature rise rate of the refrigeration appliance. The calculated temperature rise rate can be stored in a non-volatile memory of the refrigeration appliance to ensure power loss.
In particular implementations, the rate of temperature rise of the refrigeration appliance may be affected by a number of factors, such as ambient temperature, the number of items in the storage compartment, and so forth, and thus the rate of temperature rise of the refrigeration appliance may be periodically calculated and the stored rate of temperature rise updated.
In the specific implementation, the opening and closing state and the opening and closing time point of the door of each storage compartment 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 state and the opening and closing time point of the door of each storage compartment and the temperature rise rate of each storage time.
In an embodiment of the present invention, the mute period may be determined according to the usage habit of the user on the refrigeration appliance. For example, the situation where the user opens and closes the doors of the storage compartments is mainly concentrated between 7:00 and 22:00 per day, whereas in 22: between 00 and 7:00 of the following day, the door of the refrigerator was not opened, from which it can be concluded that the door was closed at 22: the probability that the rest time period of the user is 7:00 of 00 to the next day is high, and in order to reduce the influence of noise generated when the refrigeration appliance performs refrigeration on the rest of the user, the ratio of the noise generated when the refrigeration appliance performs refrigeration to the noise generated when the user performs the rest time period of the user is 22: all or a part of the time period from 00 to 7:00 of the next day is set as the silent period. Generally, the rest time of a user is mainly concentrated between 20:00 at night and 8:00 in the morning of the next day, and some users work at night and have a rest in the daytime, so that the silent periods set by different users are different, and the user can set the rest time according to the use habits of the user on the refrigeration appliance.
In another embodiment of the present invention, a mute time interval setting instruction may be received, and the mute time interval may be determined according to the received mute time interval setting instruction, that is, the user may set the mute time interval according to the actual requirement of the user.
In a specific implementation, considering that the work and rest time of the user may be different on the working day and the rest day, the silent period may be divided into a silent period corresponding to the working day and/or a silent period corresponding to the rest day. Wherein, the working day can refer to the working day in legal meaning, and can also refer to the actual working time of the user. The rest day can refer to national legal holidays and public holidays, and can also refer to rest time when the user does not work.
In specific implementation, when the silent period when the detection distance enters the refrigeration appliance is the first time length, whether the current refrigerating capacity in each storage compartment meets the corresponding reserved refrigerating capacity or not can be respectively calculated according to the temperature rise rate respectively corresponding to each storage compartment of the refrigeration appliance.
Specifically, the current temperature in each storage room is obtained, the temperature in each storage room when the storage room enters the silent time period is calculated according to the temperature rise rate corresponding to each storage room and the current temperature corresponding to each storage room, whether the temperature in each storage room meets the corresponding preset temperature or not is judged when the storage room enters the silent time period, 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 rooms meet the corresponding preset temperatures, judging that the current cold quantity meets the corresponding reserved cold quantity.
And 12, when detecting that the current cold quantity in the ith storage room does not meet the corresponding reserved cold quantity, calculating the precooling moment of the ith storage room according to the temperature drop rate of the ith storage room.
In a specific implementation, the rate of temperature drop for each storage compartment may be calculated as follows: when the compressor works, recording the temperature drop time required for reducing the current temperature in each storage room to the preset temperature corresponding to each storage room respectively, and calculating the temperature drop rate corresponding to each storage room respectively according to the difference value between the current temperature in each storage room and the preset temperature corresponding to each storage room respectively and the temperature drop time corresponding to each storage room respectively. Depending on the function of each storage compartment, the corresponding temperature drop rate may be different, for example, the temperature drop rate of the cold compartment may be different from the temperature drop rate of the freezer compartment.
In implementations, the calculated temperature drop rate may be saved 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 room is detected not to meet the corresponding reserved cold quantity, the precooling time of the ith storage room is calculated according to the temperature drop rate of the ith storage room, i is more than or equal to 1 and less than or equal to N, and N is the total number of the storage rooms of the refrigerating appliance. Specifically, the current temperature in each storage compartment may be acquired, 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 room, the time required for reducing the current temperature to the preset temperature can be calculated, and therefore the precooling time of each storage room is calculated and obtained in combination with the starting time of the silent period. For example, 30 minutes are required to decrease from the current temperature to the preset temperature, the start time of the silent period is 22:00, and the precooling time is 21: 30. For another example, if it takes 30 minutes to reduce the current temperature to the preset temperature, and the starting time of the silent period is 22:00, the precooling time is 21:20, and precooling is performed in advance to ensure that the temperature in each storage compartment can reach the preset temperature when the silent period is started.
When the pre-cooling moments corresponding to the storage compartments of the refrigerating appliance are different, the pre-cooling moment far away from the silent period can be used as the adopted silent moment to ensure that all the storage compartments can reduce the temperature to the preset temperature so as to ensure sufficient cold quantity.
In a specific implementation, the set temperatures of the storage compartments with different functions are different, and correspondingly, the corresponding preset temperatures are different. For example, the preset temperature of the storage compartment may be 2 ℃ less than the set temperature. When the set temperature of the storage room for cold storage 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 may be set according to different factors, such as actual requirements, actual application scenarios, types of refrigeration appliances, and types of storage compartments, and the specific value of the preset temperature is not limited herein.
And step 13, controlling a compressor of the refrigeration device to work to start refrigeration when the precooling time is reached.
In a specific implementation, when the precooling time is reached, the compressor of the refrigeration device can be controlled to start working to perform refrigeration. If the compressor works according to a normal refrigeration program when the precooling moment is reached, the compressor can continue to work to ensure that the reserved cold quantity is sufficient after the compressor enters a silent period. In the silent period, in the case where the reserved cooling capacity is sufficient, even if the compressor is stopped, the temperature in each storage compartment after the temperature rise is still within the set appropriate temperature range.
And step 14, when the current time is detected to be in a mute period, controlling the compressor to stop.
In an implementation, when the detected current time is in a silent period, namely, in the silent period, the compressor is controlled to stop.
According to the scheme, when the mute time interval of the distance entering the refrigeration appliance is detected to be the first time length, whether the current cold quantity in each storage room of the refrigeration appliance meets the reserved cold quantity or not is judged, and when the reserved cold quantity is not met, the refrigeration is carried out in advance, so that after the compressor stops after the compressor enters the mute time interval, sufficient cold quantity still can exist in each storage room of the refrigeration appliance, and the actual requirement is met. Can set for the silence period according to user's rest time, because the compressor is shut down at the silence period to can not produce the noise, consequently, can solve at night or user's rest time, the influence of refrigerator noise to the user improves user experience.
In particular implementations, as the compressor is shut down during periods of silence, the temperature within each storage compartment will gradually increase at a corresponding rate of temperature rise. Normally, the temperature after the rise is still within the set proper temperature range during the whole silent period, but in view of the influence of the set length of the silent period, the amount of food stored in the refrigeration appliance, the conditions of opening and closing the door of the refrigeration appliance during the silent period, the ambient temperature of the refrigeration appliance, and the like, the temperature may rise to exceed the set proper temperature range. In order to maintain the temperature in each storage room while taking into account the noise effect, when the temperature in the jth storage room for non-freezing is detected to be higher than a set first threshold value, the embodiment of the invention controls the cooling capacity distribution fan to be started so as to send the cooling capacity in at least one storage room for freezing to the jth storage room, wherein j is more than or equal to 1 and less than or equal to M, and M is the total number of the storage rooms for non-freezing in the refrigeration appliance. Since the temperature in the storage compartments for freezing is generally low, and the effect on the preservation of food is small as long as the temperature is maintained below 0 ℃, the cold in the storage compartments for freezing is transferred to the non-freezing storage compartments, the temperature of each storage compartment can be equalized without turning on the compressor, and the rest of the user is prevented from being affected by noise.
In particular implementations, the first threshold for non-refrigerated storage compartments may be set according to the type of storage compartment, and the first threshold may be different for different storage compartments. 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 temperature-changing chamber may be 2 ℃ higher than the set temperature, and when the set temperature is 0 ℃, the first threshold is 2 ℃. It will be appreciated that the first threshold value for each storage compartment may be set according to the type of storage compartment and the actual application requirements.
In a specific implementation, when the refrigeration appliance is in the silent period, if the temperature in the storage compartment 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 within 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 compartment for freezing can be controlled without generating large noise to affect the rest of the user.
For example, the second threshold value corresponding to the freezing chamber may be 4 ℃ higher than the set temperature, and the first threshold value may be-14 ℃ when the set temperature is-18 ℃.
In specific implementation, for some frost-free refrigerators, a defrosting operation needs to be performed periodically, and when the defrosting time of the refrigeration appliance is detected to be in the silent period, the defrosting time is adjusted to be before or after the silent period. Thereby avoiding the noise caused by the high-speed operation of the compressor during the defrosting period.
In the practice of the invention, the compressor is controlled to start or stop depending on the actual temperature in each storage compartment after the end of the quiet period is detected.
In order to facilitate better understanding and implementation of the present invention for those skilled in the art, the embodiment of the present invention further provides a control device for a refrigeration appliance.
