The disclosure provides a control method of a refrigerator, wherein the refrigerator comprises a refrigerator chamber, a compressor for refrigerating the refrigerator chamber and a defrosting device for heating the refrigerator chamber to perform defrosting treatment on the refrigerator chamber. The defrosting treatment of the refrigerator compartment is automatically triggered when a preset condition is met. For example: defrosting the refrigerator chamber automatically every 24 hours; or, the defrosting treatment is automatically carried out on the refrigerator chamber every time frosting in the refrigerator chamber is detected to reach a preset area threshold value. Generally, when the defrosting process is performed, the refrigerator controls the compressor to be in a closed state, and stops cooling the refrigerator compartment.
Fig. 1 shows a flowchart of a control method of a refrigerator according to an embodiment of the present disclosure, the method including:
step S110, monitoring the compartment temperature of the refrigerator compartment;
step S120, when the compressor is detected to be in a closed state and the temperature of the compartment is high Yu Dengyu by a first temperature threshold value, controlling the compressor to run at a first rotating speed;
step S130, when the temperature of the compartment is detected to be higher than or equal to a second temperature threshold, determining whether defrosting processing is performed in a target period that the temperature of the compartment is higher than or equal to the second temperature threshold, wherein the first temperature threshold is lower than the second temperature threshold;
step S140, if the defrosting process is performed in the target period, controlling the compressor to operate at a second rotation speed, where the first rotation speed is lower than the second rotation speed, and a rotation speed difference between the first rotation speed and the second rotation speed is less than or equal to a preset first rotation speed difference threshold.
In the embodiment of the disclosure, a refrigerator monitors compartment temperature of a refrigerator compartment, wherein a first temperature threshold is a starting temperature threshold for triggering the compressor to start, the compressor runs at a first rotating speed when the compressor is triggered to start, and the first temperature threshold is lower than a second temperature threshold. When the temperature of the compartment is detected to be higher than or equal to a second temperature threshold, if defrosting is carried out during the period that the temperature of the compartment is increased to be higher than or equal to the second temperature threshold, the compressor is controlled to operate at a second rotating speed, wherein the first rotating speed is lower than the second rotating speed, and the rotating speed difference between the first rotating speed and the second rotating speed is smaller than or equal to a preset first rotating speed difference threshold.
Therefore, in the embodiment of the disclosure, when the abnormal temperature rise of the compartment of the refrigerator compartment is related to the defrosting process, the rotating speed of the compressor is controlled to be increased, and the increase range is within the control range. The noise caused by the increase of the rotating speed can be controlled within the control range by controlling the increase of the rotating speed within the control range, so that the abnormal temperature rise of the compartment can be quickly reduced, and the problem that the user is not well experienced due to the noise increase from the user perspective is avoided.
In the embodiment of the disclosure, the refrigerator continuously monitors the compartment temperature of the refrigerator compartment during the power-on operation. The refrigerator compartment can be a refrigerating compartment or a freezing compartment.
In the embodiment of the disclosure, in the process of monitoring the compartment temperature of the refrigerator compartment, when the compressor is detected to be in the off state and the compartment temperature is higher than Yu Dengyu by a first temperature threshold value, the compressor is controlled to operate at a first rotating speed. Namely, the first temperature threshold is a starting temperature threshold for triggering the starting of the compressor.
For example: the starting temperature threshold of the refrigerating chamber is 8 ℃, namely the first temperature threshold is 8 ℃. Under the condition of not considering the influence of other refrigerator controls, when the temperature of the refrigerating chamber is less than 8 ℃, the compressor can be in an on state or an off state; however, when the temperature of the refrigerating chamber is equal to 8 ℃ or higher than 8 ℃, the compressor must be in an open state and operated at 1500r/min, i.e. the first rotation speed is 1500r/min.
In the embodiment of the disclosure, during the normal operation of the refrigerator, except for the defrosting process and the condition that the user opens the compartment door body (for example, the user opens the compartment door body for a long time, or the user opens the compartment door body to plug a large amount of articles into the refrigerator compartment), the peak of the compartment temperature basically does not exceed the first temperature threshold, or only temporarily exceeds the first temperature threshold by a small amplitude. The temperature of the compartment is raised to the second temperature threshold value at least caused by one of defrosting and opening of a compartment door body by a user. Generally, when a defrosting process (whether a refrigerating chamber is defrosted or a freezing chamber is defrosted) is performed, a refrigerator controls a compressor to be turned off to stop cooling, and then controls a defrosting device to heat a corresponding refrigerator compartment to complete defrosting.
For example: the starting temperature threshold value of the refrigerating chamber, namely the first temperature threshold value is 8 ℃, and the second temperature threshold value is 15 ℃. During the normal operation of the refrigerator, the temperature of the refrigerating chamber is only raised to 15 ℃ or above 15 ℃ under three conditions that defrosting treatment is carried out, or a user opens the refrigerating chamber door body, or the user opens the refrigerating chamber door body during the defrosting treatment.
In the embodiment of the present disclosure, when it is detected that the temperature of the compartment is increased to be equal to or higher than the second temperature threshold, the refrigerator determines whether the defrosting process is performed during the period in which the temperature of the compartment is increased to be equal to or higher than the second temperature threshold. If the defrosting process is performed in the target period, the room temperature is increased to be equal to or higher than the second temperature threshold value, which is related to the defrosting process, and the compressor is controlled to operate at the second rotating speed in the case that the occurrence of the defrosting process is random for the user. The first rotating speed is lower than the second rotating speed, and the rotating speed difference between the first rotating speed and the second rotating speed is smaller than or equal to a preset first rotating speed difference threshold value. That is, the rotational speed of the compressor is controlled to be increased, and the magnitude of the increase is within the control range.
In an embodiment, the method further comprises:
acquiring a preset first noise improvement threshold;
a first speed difference threshold is determined based on the first noise rise threshold.
In this embodiment, the first speed difference threshold is determined based on a preset first noise rise threshold.
Specifically, the first noise rise threshold may be preset empirically or according to the related research result. And then, a first speed difference threshold corresponding to the first noise lifting threshold can be determined according to an ideal linear relation between the noise and the rotating speed, and a first speed difference threshold corresponding to the first noise lifting threshold can also be determined according to an actual test.
For example: the developer determines from noise-related studies that the maximum tolerance of the user to sudden noise rise without active action is 3 db. And 3 decibels are used as a first noise improvement threshold value by a developer to be input into the refrigerator to be delivered from the factory after the assembly is finished.
The refrigerator starts automatic testing, namely the compressor is controlled to operate at a first rotating speed r1, the noise value at the moment is determined to be 37 decibels according to the noise sensor, the rotating speed of the compressor is continuously increased, and meanwhile the noise value is monitored until the noise value reaches 40 decibels, and the rotating speed r2 of the compressor at the moment is determined. Therefore, the refrigerator can determine that the first speed difference threshold corresponding to the first noise rise threshold of 3 decibels is | r2-r1|.
Therefore, after the refrigerator is put into use, when the temperature of the compartment is detected to be increased to be higher than or equal to the second temperature threshold value, if the defrosting treatment is carried out in the determined target period, the compressor is controlled to operate at the second rotating speed. The second rotation speed may be r2 in the automatic test, or may be a rotation speed between the first rotation speed r1 and the second rotation speed r2.
The embodiment has the advantages that the first speed difference threshold value is determined according to the first noise rise threshold value, so that the noise rise caused by the increase of the rotating speed of the compressor in the control of the refrigerator is within the accurate noise control range, and the accuracy of the noise control is improved.
It is to be understood that this embodiment is only an exemplary illustration, and the first speed difference threshold may be directly preset empirically, in addition to the determination of the first speed difference threshold based on noise, and this embodiment should not limit the function and the range of use of the present disclosure.
In an embodiment, the method further comprises: and if the defrosting treatment is not carried out in the target period, controlling the compressor to operate at a third rotating speed, wherein the first rotating speed is lower than or equal to the third rotating speed.
In this embodiment, if the defrosting process is not performed in the target period, the refrigerator may increase the rotation speed of the compressor and may maintain the rotation speed of the compressor based on the first rotation speed when the compressor is turned on.
Specifically, when it is detected that the temperature of the compartment is increased to be equal to or higher than the second temperature threshold value, if the defrosting process is not performed in the target period, it indicates that the cooling stop due to the turning-off of the compressor due to the defrosting process does not occur in the target period. In this case, the refrigerator controls the compressor to operate at the third rotation speed for the purpose of rapidly reducing the temperature of the compartment, wherein the first rotation speed is lower than or equal to the third rotation speed. That is, the refrigerator can control the compressor to maintain the rotating speed unchanged, and rapidly reduce the temperature of the compartment through other control (such as increasing the rotating speed of the fan); the compartment temperature can also be rapidly reduced by increasing the rotational speed of the compressor.
In an embodiment, the method further comprises: and controlling the second rotating speed to be lower than the third rotating speed, wherein the rotating speed difference between the first rotating speed and the third rotating speed is less than or equal to a preset second rotating speed difference threshold value.
In this embodiment, the increase in the rotation speed of the compressor is greater when the defrosting process is not performed during the target period than when the defrosting process is performed during the target period.
Specifically, if the defrosting process is not performed in the target period, it indicates that the temperature of the compartment is raised to be higher than or equal to the second temperature threshold on the premise that the refrigerator normally operates, which is completely caused by the opening of the compartment door body, and the opening of the compartment door body is usually related to the active action of the user (for example, the user manually opens the compartment door body). Therefore, the rotation speed of the compressor is further increased within a certain range, and the user can understand that the noise value is increased to some extent. The second rotating speed is controlled to be lower than the third rotating speed, and the rotating speed difference between the second rotating speed and the third rotating speed is smaller than or equal to a preset second rotating speed difference threshold value, so that the rotating speed of the compressor is further increased, and the increasing amplitude is within a control range.
The embodiment has the advantage that compared with the condition that the defrosting process is carried out in the target period, in the condition that the defrosting process is not carried out in the target period, the rotating speed of the compressor is further increased, and the increased amplitude is within the control range, so that the temperature reduction speed is further increased, and the brought noise rise is still within the tolerance range of a user.
In an embodiment, the method further comprises:
acquiring a preset second noise improvement threshold;
a second speed difference threshold is determined based on the second noise rise threshold.
In this embodiment, the second rotational speed difference threshold is determined based on a preset second noise rise threshold.
Specifically, the second noise rise threshold may be preset empirically or according to the related research result, similarly to the setting of the first noise rise threshold. And then, a second rotation speed difference threshold corresponding to the second noise lifting threshold can be determined according to an ideal linear relation between the noise and the rotation speed, and a second rotation speed difference threshold corresponding to the second noise lifting threshold can also be determined according to an actual test.
For example: the developer determines from the noise-related studies that the maximum tolerance of the user to sudden noise rise without active action is 3 db and the maximum tolerance to sudden noise rise with active action is 5 db. And 3 decibels are used as a first noise improvement threshold value by a developer, and 2 decibels are used as a second noise improvement threshold value on the basis of the first noise improvement threshold value and are input into the refrigerator to be delivered from the factory after the refrigerator is assembled.
The refrigerator starts automatic testing, namely the compressor is controlled to operate at a first rotating speed r1, the noise value at the moment is determined to be 37 decibels according to the noise sensor, the rotating speed of the compressor is continuously increased, and meanwhile the noise value is monitored until the noise value reaches 40 decibels, and the rotating speed r2 of the compressor at the moment is determined; and continuing to increase the rotating speed of the compressor until the noise value reaches 42 decibels and determining the rotating speed r3 of the compressor at the moment. Therefore, the refrigerator can determine that the first rotating speed difference threshold value corresponding to the first noise improvement threshold value of 3 decibels is | r2-r1|, and the second rotating speed difference threshold value corresponding to the second noise improvement threshold value of 2 decibels is | r3-r2|.
Therefore, after the refrigerator is put into use, when the temperature of the compartment is detected to be increased to be higher than or equal to the second temperature threshold value, the compressor is controlled to operate at the second rotating speed if the defrosting treatment is carried out in the determined target period, or the compressor is controlled to operate at the third rotating speed if the defrosting treatment is not carried out in the determined target period. The second rotation speed can be r2 in automatic test, or can be a rotation speed between the first rotation speed r1 and the second rotation speed r2; the third rotation speed may be r3 in the automatic test, or may be a rotation speed between the second rotation speed and r3.
The embodiment has the advantage that the noise caused by the further increase of the rotating speed of the compressor in the refrigerator control is further increased within the accurate noise control range by determining the second rotating speed difference threshold according to the second noise increase threshold, so that the accuracy of the noise control is improved.
It is to be understood that this embodiment is only an exemplary illustration, and that the second rotational speed difference threshold value may be directly preset empirically, in addition to the determination of the second rotational speed difference threshold value based on noise, and this embodiment should not limit the function and the range of use of the present disclosure.
In one embodiment, the refrigerator further comprises a fan for promoting cold circulation, and when the compressor is detected to be in an off state and the compartment temperature is higher than Yu Dengyu by a first temperature threshold value, the control of the compressor to operate at a first rotating speed comprises the following steps: when the compressor is detected to be in a closed state and the room temperature is Yu Dengyu higher than a first temperature threshold value, controlling the compressor to operate at a first rotating speed and controlling the fan to operate at a fourth rotating speed;
controlling the compressor to operate at a second rotational speed if the defrosting process is performed during the target period, including: and if the defrosting treatment is carried out in the target period, controlling the compressor to operate at the second rotating speed and controlling the fan to operate at the fifth rotating speed, wherein the fourth rotating speed is lower than or equal to the fifth rotating speed.
In the embodiment, the refrigerator is used for manufacturing cold energy by starting the compressor, and the higher the rotating speed of the compressor is, the more the cold energy is manufactured; the cooling capacity circulation is promoted by turning on the fan, and the cooling capacity circulation is faster as the rotating speed of the fan is higher.
When the compressor is detected to be in the closed state and the compartment temperature is higher than Yu Dengyu a first temperature threshold value, the refrigerator controls the compressor to operate at a first rotating speed and controls the fan to operate at a fourth rotating speed. When it is detected that the temperature of the compartment is increased to be equal to or higher than the second temperature threshold, the refrigerator determines whether or not the defrosting process is performed during the target period. If the defrosting process is performed in the target period, the refrigerator can increase the rotating speed of the compressor and increase the rotating speed of the fan at the same time, namely, the compressor is controlled to operate at the second rotating speed (higher than the first rotating speed) and the fan is controlled to operate at the fifth rotating speed (higher than Yu Dengyu fourth rotating speed).
The advantage of this embodiment is that the effect of rapid cooling is further enhanced by increasing the rotational speed of the compressor and to some extent the rotational speed of the fan when abnormal temperature rise is associated with defrosting.
In an embodiment, the method further comprises: and if the defrosting treatment is not carried out in the target period, controlling the compressor to operate at a third rotating speed and controlling the fan to operate at a sixth rotating speed, wherein the first rotating speed is lower than or equal to the third rotating speed, and the fourth rotating speed is lower than or equal to the sixth rotating speed.
In this embodiment, if the defrosting process is not performed during the target period, the refrigerator may select at least one of the two control operations of increasing the rotation speed of the compressor and increasing the rotation speed of the fan.
Specifically, if the defrosting process is not performed in the target period, it is described that the cooling stop due to the compressor being turned off by the defrosting process does not occur in the target period, and the refrigerator may increase the rotational speed of the fan while maintaining the rotational speed of the compressor, and may increase the rotational speed of the fan while increasing the rotational speed of the compressor. That is, the compressor is controlled to operate at the third rotational speed and the fan is controlled to operate at the sixth rotational speed. The first rotating speed is lower than or equal to the third rotating speed, and the fourth rotating speed is lower than or equal to the sixth rotating speed.
In an embodiment, the method further comprises: and when the refrigerator compartment is a refrigerating compartment, controlling the first rotating speed to be lower than the third rotating speed and the fourth rotating speed to be lower than or equal to the sixth rotating speed, or controlling the first rotating speed to be equal to the third rotating speed and the fourth rotating speed to be lower than the sixth rotating speed.
In this embodiment, when the refrigerator compartment is a refrigerating compartment and it is detected that the temperature of the refrigerating compartment is increased to be greater than or equal to the second temperature threshold, if the defrosting process is not performed in the target period, it indicates that the refrigeration stop caused by the turning-off of the compressor due to the defrosting process does not occur in the target period. The refrigerator can only increase the rotating speed of the compressor, and can increase the rotating speed of the fan while increasing the rotating speed of the compressor, namely, the first rotating speed is controlled to be lower than the third rotating speed and the fourth rotating speed is controlled to be lower than or equal to the sixth rotating speed; it is also possible to increase only the rotational speed of the fan, i.e. to control the first rotational speed to be equal to the third rotational speed and the fourth rotational speed to be lower than the sixth rotational speed.
In an embodiment, the method further comprises: and when the refrigerator compartment is a freezing compartment, controlling the first rotating speed to be lower than the third rotating speed and controlling the fourth rotating speed to be lower than or equal to the sixth rotating speed.
In this embodiment, when the compartment of the refrigerator is a freezing compartment and it is detected that the temperature of the freezing compartment is increased to be greater than or equal to the second temperature threshold, if the defrosting process is not performed in the target period, it indicates that the refrigeration stop caused by the turning-off of the compressor due to the defrosting process does not occur in the target period. The refrigerator increases the rotational speed of the compressor and also the rotational speed of the fan due to the functional demand for the freezing compartment, i.e., the first rotational speed is controlled to be lower than the third rotational speed and the fourth rotational speed is controlled to be lower than or equal to the sixth rotational speed.
Fig. 2 shows a flowchart of a refrigerator control when a refrigerator compartment is a refrigerating compartment according to an embodiment of the present disclosure.
In this embodiment, the refrigerating room temperature is Tc, the first temperature threshold of the refrigerating room is Tc1, and the second temperature threshold of the refrigerating room is Tc2.
The refrigerator monitors the refrigerating compartment temperature Tc. When the compressor is in a closed state, the refrigerator determines whether Tc is equal to or greater than Tc1. If Tc is less than Tc1, the refrigerator continues to maintain the compressor in the closed state; and if Tc is more than or equal to Tc1, controlling the compressor to operate at the rotating speed r1 by the refrigerator.
When the compressor is operated at the rotation speed r1, the refrigerator determines whether Tc is warmed up to Tc2 or more. If Tc is less than Tc2, the refrigerator continues to maintain the compressor to operate at the rotating speed r 1; if Tc is equal to or greater than Tc2, the refrigerator determines whether the defrosting process has been performed during the target period.
If the defrosting treatment is carried out in the target period, the refrigerator controls the compressor to operate at a rotating speed r2, wherein r1 is smaller than r2; if the defrosting process is not performed in the target period, the rotational speed of the fan is increased while the compressor is maintained to be operated at the rotational speed r 1.
It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and the scope of the disclosure.
Fig. 3 shows a flowchart of a refrigerator control when a refrigerator compartment is a freezing compartment according to an embodiment of the present disclosure.
In this embodiment, let the freezer compartment temperature be Td, the first temperature threshold for the freezer compartment be Td1, and the second temperature threshold for the freezer compartment be Td2.
The refrigerator monitors the freezer compartment temperature Td. When the compressor is in a turn-off state, the refrigerator determines whether Td is equal to or greater than Td1. If Td is less than Td1, the refrigerator continuously maintains the compressor in a closed state; if Td is greater than or equal to Td1, the refrigerator controls the compressor to operate at the rotating speed r 1.
When the compressor is operated at the rotational speed r1, the refrigerator determines whether Td is warmed up to be equal to or greater than Td2. If Td is less than Td2, the refrigerator continuously keeps the compressor running at the rotating speed r 1; if Td is equal to or greater than Td2, the refrigerator determines whether or not the defrosting process is performed during the target period.
If the defrosting treatment is carried out in the target period, the refrigerator controls the compressor to operate at a rotating speed r2, wherein r1 is smaller than r2; if the defrosting process is not performed in the target period, the refrigerator controls the compressor to operate at a rotating speed r3, wherein r2 is less than r3.
It should be noted that the embodiment is only an example and should not limit the function and the application scope of the disclosure.
Fig. 4 shows a flowchart of execution logic of a refrigerator control according to an embodiment of the present disclosure.
In this embodiment, when it is detected that the compartment temperature T is equal to or higher than the second temperature threshold value T2, it is determined whether or not the defrosting process has occurred during the abnormal temperature rise. If the defrosting treatment is carried out, the rotating speed of the compressor is increased by 1 gear according to the ambient temperature of the environment where the refrigerator is located.
If the defrosting process does not occur, it can be determined that the abnormal temperature rise is caused by the fact that the compartment door body is opened manually by the user, and the refrigeration stop caused by the fact that the compressor is closed by the defrosting process does not occur in the abnormal temperature rise period. It is further determined whether it is the refrigerating compartment abnormal temperature rise, that is, whether the refrigerating compartment temperature Tc is equal to or greater than the second temperature threshold value Tc2 of the refrigerating compartment. If the refrigerating chamber is abnormally heated, namely the refrigerating chamber temperature Tc is greater than or equal to the second temperature threshold Tc2 of the refrigerating chamber, the refrigerator maintains the rotating speed of the compressor and increases the rotating speed of the fan by 1 step.
If the abnormal temperature rise of the refrigerating chamber is determined, namely the temperature Tc of the refrigerating chamber is smaller than the second temperature threshold Tc2 of the refrigerating chamber, the abnormal temperature rise of the freezing chamber is determined, and the refrigerator controls the compressor to operate at the preset rotating speed N. Further, the rotation speed N may be higher than the rotation speed of the compressor after the rotation speed N is increased by 1 st gear when the defrosting process occurs.
It should be noted that the embodiment is only an exemplary illustration, and should not limit the function and the scope of the disclosure.
