Generally, the refrigerating chamber of the refrigerator is provided with a corresponding temperature detection device for detecting the temperature of the refrigerating chamber, and the temperature detection device is generally arranged at a position which can accurately sense the temperature of the refrigerating chamber and is not easy to be blocked by food, for example, the temperature detection device is arranged on the surface of a refrigerating chamber liner or behind an air duct cover plate.
The conventional cooling modes in the refrigerating chamber are: the shutdown temperature and the startup temperature are preset, for example, 3 ℃ is the shutdown temperature, 7 ℃ is the startup temperature, namely when the temperature detection device detects that the temperature is lower than 3 ℃, the refrigeration system is controlled to stop refrigerating, and when the temperature detection device detects that the temperature is higher than 7 ℃, the refrigeration system is controlled to start refrigerating. Thereby ensuring that the temperature of the refrigerating chamber is controlled within the temperature interval of 3-7 ℃.
However, the following situations often exist in the using process: when a user places food with higher temperature near the temperature detection device, the temperature of a local area near the temperature detection device will rise, and the temperature detected by the temperature detection device will also rise accordingly. According to a conventional refrigeration mode, as long as the temperature value detected by the temperature detection device is higher than the starting temperature, the refrigeration system can continuously refrigerate, because the temperature of food near the temperature detection device is higher, the refrigeration needs a longer time to be enough to enable the temperature detected by the temperature detection device to be recovered to a set temperature interval, and the refrigeration for a long time can cause the temperature of other areas of the refrigerating chamber to be too low, so that the foods placed in other areas are frozen or frozen, and the normal use of the refrigerating chamber is influenced.
In order to solve the above problems, the present application provides a refrigerator, a control method of the refrigerator, a system, and a computer-readable storage medium.
In one embodiment, the application provides a control method of a refrigerator.
Referring to fig. 1, the refrigerator includes a refrigerating chamber and a refrigerating system for refrigerating the refrigerating chamber, a temperature detection device for detecting a temperature of the refrigerating chamber is disposed in the refrigerating chamber, and one or at least two temperature detection devices may be disposed in the refrigerating chamber. Referring to fig. 2, a method for controlling a refrigerator provided in an embodiment of the present application includes the steps of:
and step S20, when the refrigerating chamber is detected to be in the door opening state, acquiring the current first temperature value of the refrigerating chamber detected by the temperature detection device.
The refrigerating chamber is generally provided with corresponding door bodies, and the opening or closing of the refrigerating chamber is realized by opening or closing the door bodies. When the refrigerator is used, a user needs to open the door body of the refrigerating chamber and then put food into the refrigerating chamber. Therefore, when the refrigerating chamber is detected to be in the door opening state, the current temperature detected by the temperature detection device is acquired, so that whether the food with the overhigh temperature is placed in the refrigerating chamber by a user or not is comprehensively judged in combination with the subsequent steps. The temperature obtained when the refrigerating chamber is detected to be in the on-off state is recorded as a first temperature value.
It should be noted that, in general, the real-time state (including the door opening state and the door closing state) of the door body of the refrigerating chamber may be detected, and in the actual application process, when the user opens the door body of the refrigerating chamber, it may be detected that the refrigerating chamber is in the door opening state, and at this time, the current first temperature value of the refrigerating chamber detected by the temperature detection device is obtained.
Step S30, when it is detected that the refrigerating compartment is in a door-closed state, acquiring a current second temperature value of the refrigerating compartment detected by the temperature detection device after a first preset time period of the door-closed state, where the door-closed state is a state in which the refrigerating compartment is subjected to a door-closing motion after being in the door-opened state.
Generally, a user can close a door body of the refrigerating chamber after food is placed in the refrigerating chamber, detects that the refrigerating chamber is in a door closing state at the moment, waits for a first preset time after the door closing state is detected, and then obtains a current temperature value detected by the temperature detection device, wherein the current temperature value is recorded as a second temperature value in the application.
When both the door-open state and the door-closed state are detected, it can be determined that the user has completed the operation of the refrigerating compartment, and there is a possibility that food or other articles are placed in the refrigerating compartment.
When the refrigerating chamber is opened, hot air from the outside may enter the refrigerating chamber, which increases the temperature in the refrigerating chamber, and when food having a high temperature is put into the refrigerating chamber, the temperature in the refrigerating chamber also increases. The situation that the temperature is increased due to the entering of the hot air disappears quickly after the door is closed (namely, the temperature of the refrigerating chamber is reduced quickly after the door is closed), and the temperature is higher after the food with higher temperature is placed and continues for a period of time after the door is closed, so that the situation that the temperature is increased due to the entering of the external hot air is eliminated, and the current second temperature value of the refrigerating chamber detected by the temperature detection device is acquired after the first preset time period of the door closing state.
It should be noted that, in the refrigerating chamber use, a plurality of door opening and closing processes may occur, and each door opening and closing process can detect the door opening state and the door closing state, and the detection of the door opening state and the door closing state recorded in the present application means that the door opening state and the door closing state in the same door opening and closing process are detected, that is, when a user opens a refrigerating chamber door body, the door opening state is detected, and then when the user completes the use of the refrigerating chamber and closes the refrigerating chamber door body, the door closing state is detected.
And step S40, if the difference between the first temperature value and the second temperature value is greater than or equal to a first preset threshold value, controlling the refrigeration system to be switched from a normal refrigeration mode to a preset refrigeration mode, wherein the refrigeration time length in the preset refrigeration mode is less than the refrigeration time length in the normal refrigeration mode.
When the first temperature value and the second temperature value are obtained, the temperature difference value between the first temperature value and the second temperature value can be calculated, the temperature difference value is compared with a first preset threshold value, if the temperature difference value is larger than or equal to the first preset threshold value, the temperature of the refrigerating chamber is increased after a period of time after the door is closed, the refrigerating chamber is continuously high, accordingly, it can be judged that a user places food with high temperature in the refrigerating chamber and places the food in a region near the temperature detection device, and at the moment, the refrigerating system is controlled to be switched from the normal refrigerating mode to the preset refrigerating mode.
It should be noted that the normal refrigeration mode is the aforementioned refrigeration mode that is controlled according to the start-up temperature and the stop temperature, and since the temperature of the area near the temperature detection device is continuously higher, if the refrigeration system is in the normal refrigeration mode, the refrigeration system will keep the refrigeration state until the temperature detected by the temperature detection device reaches the stop temperature, which may result in the temperature of the area outside the area near the temperature detection device being too low. Therefore, after the food with higher temperature is placed in the refrigerator chamber, the refrigeration mode is preset by the refrigeration system, the refrigeration time of the preset refrigeration mode is shorter than that of the normal refrigeration mode, so that the temperature in the refrigerator chamber cannot be reduced too much, the condition that the temperature of the region outside the region where the food with higher temperature is placed is too low to cause freezing damage or freezing of the food or the articles and the like is avoided, and the refrigerator chamber can be normally used.
Referring to fig. 3, in one embodiment, the method for controlling a refrigerator provided in this embodiment further includes:
and step S10, acquiring the state of the door lamp switch of the refrigerating chamber.
And step S11, determining whether the refrigerating chamber is in the door opening state or the door closing state according to the state of the door lamp switch.
Specifically, a door body of the refrigerating chamber and/or the interior of the refrigerating chamber is provided with a door lamp switch, when the door body of the refrigerating chamber is opened or closed, the door lamp switch is triggered, and the switch state of the door lamp switch can be correspondingly changed. According to the method, the state of the door lamp switch can be acquired, the refrigerating chamber is determined to be in the door opening state or the door closing state according to the state, and then the step S20 or the step S30 is executed.
In one embodiment, the first predetermined time period is 2 to 5 minutes. Namely, after the door closing action is detected, the current second temperature value of the refrigerating chamber detected by the temperature detection device is obtained after 2-5 minutes. The duration of 2-5 minutes is set, so that the accuracy of judgment is facilitated, and the condition that the temperature is increased due to the entering of hot air due to the fact that the time is too short is avoided being misjudged. In practice, it is preferably 3 minutes, and may be 2 minutes, 4 minutes, 5 minutes, or the like.
In one embodiment, the first predetermined threshold is 5-10 ℃. That is, when the difference between the first temperature value and the second temperature value is greater than or equal to any one of the values of 5 to 10 ℃, the refrigeration chamber is controlled to be switched from the normal refrigeration mode to the preset refrigeration mode, and the first preset threshold is set within the range of 5 to 10 ℃, which is most close to the actual situation, and is more reasonable. In practical applications, the first predetermined threshold is preferably 8 ℃, and may be 5 ℃, 6 ℃ or 10 ℃.
In one embodiment, the preset cooling mode includes: after the refrigeration system is started for a first duration, the refrigeration system is closed for a second duration of the cycle on-off mode.
Specifically, when entering the preset refrigeration mode, the refrigeration system does not perform refrigeration completely according to the conventional mode of the starting temperature and the stopping temperature, but opens for a preset first time period, closes for a preset second time period, then opens for the preset first time period, closes for the preset second time period, and then performs the cycle of opening and closing. When refrigeration is realized, the refrigerating time can be obviously shortened, the temperature in the refrigerating chamber is prevented from being reduced too much, the condition that foods or articles and the like are frozen or frozen and the like due to too low temperature of the region outside the food placing region with higher temperature is avoided, and the refrigerating chamber of the refrigerator can be normally used.
In one embodiment, the first duration is less than the second duration. That is, the time period for which cooling is turned on in each cycle is shorter than the time period for which cooling is turned off, further ensuring that the temperature of the region other than the food placement region in which the temperature in the refrigerating chamber is high is excessively low.
Specifically, the first time period and the second time period may be in the range of 10 to 20 minutes. In practical application, the first time period may be set to 10 minutes, and the second time period may be set to 20 minutes; the first time period may also be set to 15 minutes and the second time period to 20 minutes; other arrangements are also possible and are not described herein.
Referring to fig. 4, in one embodiment, after the step S40 of controlling the refrigeration system to switch from the normal refrigeration mode to the preset refrigeration mode if the difference between the first temperature value and the second temperature value is greater than or equal to the first preset threshold, the control method provided in the embodiment of the present application further includes the following steps:
and step S50, after the refrigerating system works for a second preset time according to the preset refrigerating mode, acquiring a current third temperature value of the refrigerating chamber detected by the temperature detection device.
Step S60, if the difference between the third temperature value and the first temperature value is greater than or equal to a second preset threshold value, keeping a preset refrigeration mode; otherwise, controlling the refrigeration system to recover to the normal refrigeration mode.
That is, after the refrigeration system enters the preset refrigeration mode, it needs to further determine whether the temperature in the refrigerating chamber is recovered to normal, and further determine whether to continue to maintain the preset refrigeration mode or recover to the normal refrigeration mode. Specifically, after the second preset duration of the preset refrigeration mode is entered, the current temperature detected by the temperature detection device is obtained and recorded as a third temperature value, whether the difference between the third temperature value and the first temperature value is large or not is judged, if yes, the preset refrigeration mode is continuously maintained, and if not, the normal refrigeration mode is recovered. In the application, whether the difference between the third temperature value and the first temperature value is larger is judged by comparing the temperature difference between the third temperature value and the first temperature value with a second preset threshold value, and if the temperature difference between the third temperature value and the first temperature value is larger than or equal to the second preset threshold value, the difference is still larger.
In addition, because the refrigeration system enters the preset refrigeration mode for a period of time, the temperature near the temperature detection device is necessarily reduced before being compared, therefore, the second preset threshold is set to be smaller than the first preset threshold, and the judgment rationality can be improved.
In this embodiment, the second preset time period may be determined according to an actual requirement, for example, 1 hour, 2 hours, 3 hours, and the second preset threshold may also be determined according to the actual requirement, assuming that the first preset threshold is 8 ℃, and the second preset threshold may be set to 5 ℃, 6 ℃, 7 ℃, and the like.
In one embodiment, the temperature detection device includes a temperature sensor or the like capable of performing a temperature detection function.
In another embodiment, the present embodiment provides a control system of a refrigerator, the refrigerator includes a refrigerating chamber, a refrigeration system, and a temperature detection device disposed in the refrigerating chamber, and referring to fig. 5, the control system of the present embodiment includes a first obtaining unit 20, a second obtaining unit 30, and a control unit 40.
The first acquiring unit is used for acquiring a current first temperature value of the refrigerating chamber detected by the temperature detecting device when the refrigerating chamber is detected to be in a door opening state; the second obtaining unit is used for obtaining a current second temperature value of the refrigerating chamber detected by the temperature detection device after a first preset time length of the door closing state is detected when the refrigerating chamber is detected to be in the door closing state, wherein the door closing state is a state in which the refrigerating chamber is subjected to a door closing action after being in the door opening state; the control unit is used for controlling the refrigeration system to be switched from the normal refrigeration mode to the preset refrigeration mode if the difference between the first temperature value and the second temperature value is larger than or equal to a first preset threshold value.
For specific contents of the control system of the refrigerator, reference may be made to the corresponding description in the foregoing control method of the refrigerator, and details are not repeated here.
According to the control system of the refrigerator, when the refrigerating chamber is detected to be in the door opening state, the current first temperature value of the refrigerating chamber detected by the temperature detection device is obtained, then when the refrigerating chamber is detected to be in the door closing state, the current second temperature value of the refrigerating chamber detected by the temperature detection device is obtained after the refrigerating chamber enters the door closing state for the first preset time, the first temperature value and the second temperature value are compared, if the difference between the first temperature value and the second temperature value is larger than or equal to the first preset threshold value, the refrigerating system is controlled to be switched from the normal refrigerating mode to the preset refrigerating mode, and the refrigerating time in the preset refrigerating mode is smaller than the refrigerating time in the normal refrigerating mode. From this, can judge through the first temperature value and the second temperature value that obtain at different moments that the user has placed the higher food of temperature in the freezer, and then change refrigerating system's normal refrigeration mode and adopt and predetermine the refrigeration mode, because it is long to be less than the refrigeration time under the normal refrigeration mode for predetermineeing the refrigeration time under the refrigeration mode, consequently the freezer temperature can not reduce too much in the freezer, avoid the higher food of temperature to place the temperature of the region beyond the region too low and lead to freezing damage or condition such as freezing of food or article to take place.
