Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In order to solve the problem of high power consumption of the refrigerator caused by the control logic of the conventional refrigerator, in one embodiment, as shown in fig. 1, there is provided a refrigeration control method of the refrigerator, including the steps of:
step S110, detecting the operation state of the air door when the compressor and the fan are in an on state and the temperature of the freezing chamber is detected to be less than or equal to the freezing closing temperature.
It should be noted that, the refrigeration control method of the refrigerator is implemented by the control equipment of the refrigerator. The refrigerator comprises a freezing chamber and a refrigerating chamber, when the freezing chamber needs to be refrigerated, the control device controls the compressor and the fan to be started, and when the refrigerating chamber needs to be refrigerated, the control device controls the fan and the air door to be started, so that the control device can detect the running condition of relevant equipment of the refrigerator to judge whether the freezing chamber is in a refrigerating stage or not and whether the refrigerating chamber is in the refrigerating stage or not. In the steps of the refrigeration control method of the refrigerator, when the compressor and the fan are in the on state, the refrigerating chamber is indicated to be in the refrigerating stage.
In the refrigerating stage of the freezing chamber, the control equipment detects the temperature of the freezing chamber through a temperature sensor arranged in the freezing chamber, and the temperature of the freezing chamber is the basis for judging whether to start or stop the compressor and the fan. In the conventional art, when the temperature of the freezing chamber is greater than or equal to the freezing start temperature, the compressor and the fan are turned on, and the freezing chamber starts to refrigerate; and when the temperature of the freezing chamber is less than or equal to the freezing closing temperature, the compressor and the fan are closed, and the freezing chamber stops refrigerating. The traditional control logic is changed, and after the temperature of the freezing chamber is less than or equal to the freezing closing temperature and the conditions of closing the compressor and the fan are reached, the compressor and the fan are not directly closed, but the running state of the air door is detected. The freezing closing temperature is a stop point for judging the closing of the compressor and the fan, namely, the freezing chamber reaches a set temperature, and the control equipment selects a lower limit temperature which is smaller than the set temperature and is close to the set temperature. The opposite is the freezing start temperature, and the freezing start temperature is the start point for judging and starting the compressor and the fan, namely the upper limit temperature which is selected by the control equipment near the set temperature and is larger than the set temperature is achieved by enabling the freezing chamber to reach the set temperature.
In one example, the freeze-on temperature and freeze-off temperature are obtained based on the following formulas:
LD on (freezing start temperature) =set temperature+ld d1 (freeze-on parameters)/2.
LD off (freeze off temperature) =ld on -LD d2 (freeze stop parameters)/2.
In the above formula, the freeze start parameter is used to set the freeze start temperature, and the freeze stop parameter is used to set the freeze stop temperature.
The freezing chamber needs to be started for refrigeration, and the refrigerating chamber is judged by the following conditions: and if the temperature of the freezing chamber is detected to be greater than or equal to the freezing starting temperature, controlling the compressor and the fan to be started.
In step S120, if the operation state of the damper is the open state, the temperature of the refrigerating chamber is obtained.
In order to solve the problem, when the running state of the air door is in an open state, the control equipment measures the temperature of the refrigerating chamber through a temperature sensor built in the refrigerating chamber and judges the relation between the temperature of the refrigerating chamber and the refrigerating closing temperature and the refrigerating temperature threshold value. The refrigerating closing temperature is a stopping point for judging closing of the fan and the air door, namely, the refrigerating chamber reaches the set temperature, and the control equipment selects a lower limit temperature which is smaller than the set temperature and is close to the set temperature. The opposite is the cold storage opening temperature, and the cold storage opening temperature is the starting point for judging the opening fan and the air door, namely the upper limit temperature which is selected by the control equipment near the set temperature and is larger than the set temperature is achieved by enabling the cold storage chamber to reach the set temperature.
In one example, the refrigeration on temperature and the refrigeration off temperature are obtained based on the following formulas:
LC on (refrigeration on temperature) =set temperature+lc d1 (refrigeration on parameters)/2.
LC off (refrigeration off temperature) =lc on -LC d2 (refrigerated shutdown parameter)/2.
In the above formula, the refrigeration start-up parameter is used for setting the refrigeration start-up temperature, and the refrigeration stop parameter is used for setting the refrigeration stop temperature.
The refrigeration temperature threshold is a value between the refrigeration closing temperature and the refrigeration opening temperature, namely, the refrigeration closing temperature is less than the refrigeration temperature threshold is less than the refrigeration opening temperature. In one example, the refrigeration temperature threshold is obtained in accordance with the following steps: acquiring a difference value between a refrigeration opening temperature and a refrigeration closing temperature; and obtaining the sum of the half difference value and the refrigerating closing temperature, and taking the sum as a refrigerating temperature threshold value.
In one example, the refrigeration temperature threshold is obtained based on the following formula:
LC test (refrigeration temperature threshold) = (LC) on -LC off )/2-LC off 。
In another way of judging logic, as shown in fig. 1, if detecting that the temperature of the freezing chamber is less than or equal to the freezing closing temperature, the step of detecting the operation state of the air door includes the steps of:
and step S150, if the running state of the air door is a closed state, controlling the compressor and the fan to be closed.
The operation state of the air door is detected to be in a closed state, which means that the refrigerating chamber does not need to be refrigerated, and the refrigerating chamber also reaches the shutdown condition at the moment, so that the compressor and the fan are directly controlled to be closed.
Step S130, if the temperature of the refrigerating chamber is greater than the refrigerating closing temperature and the temperature of the refrigerating chamber is less than the refrigerating temperature threshold, updating the refrigerating stop parameter to be a first type current parameter; the current secondary parameters of the first class are larger than the freezing shutdown parameters; the refrigeration temperature threshold is greater than the refrigeration off temperature and the refrigeration temperature threshold is less than the refrigeration on temperature.
When the temperature of the refrigerating chamber is greater than the refrigerating closing temperature and the temperature of the refrigerating chamber is less than the refrigerating temperature threshold, the lower half area of the refrigerating chamber between the refrigerating closing temperature and the refrigerating opening temperature is indicated, the refrigerating closing temperature can be reached by further refrigerating, in order to enable the refrigerating chamber to continue refrigerating, the control device gives the refrigerating stop parameter a new value again, namely, the refrigerating stop parameter is replaced by the first type current parameter, and the first type current parameter is set by the control device according to the actual condition of the current refrigerating cycle, and the first type current parameter is greater than the refrigerating stop parameter, and according to the formula, the LD is known off (freeze off temperature) will become smaller.
Step S140, controlling the compressor and the fan to be turned off in a delayed manner according to the first class of current parameters.
After the control device sets the first type current sub-parameters, the control device controls the compressor and the fan according to the first type current sub-parameters until the shutdown condition of the first type current sub-parameters is reached.
In one example, as shown in fig. 2, the step of controlling the compressor and the fan to be turned off in a delayed manner according to the first type of current sub-parameter includes the steps of:
step S210, updating the freezing closing temperature according to the current parameters of the first class.
And step S220, if the temperature of the freezing chamber is less than or equal to the updated freezing closing temperature, the compressor and the fan are controlled to be closed.
The freeze off temperature is updated based on the following formula:
LD off (freeze off temperature) =ld on -LD gx1 (first class current minor parameter)/2.
Therefore, the updated freezing closing temperature is smaller than the freezing closing temperature before updating, and the compressor and the fan need to continuously work the temperature of the freezing chamber to meet the condition of being smaller than or equal to the freezing closing temperature, so that compared with the normal shutdown condition, the compressor and the fan are delayed to be closed, and synchronous refrigeration of the freezing chamber and the refrigerating chamber is realized.
In another way of determining logic, as shown in fig. 1, if the operation state of the damper is an open state, the step of acquiring the temperature of the refrigerating chamber includes the steps of:
step S160, if the temperature of the refrigerating chamber is greater than the refrigerating temperature threshold and the temperature of the refrigerating chamber is less than the refrigerating opening temperature, updating the refrigerating stop parameter to be the second type current parameter; the second class of current parameters are larger than the freezing shutdown parameters; the second class of current sub-parameters is greater than the first class of current sub-parameters.
Step S170, controlling the compressor and the fan to be turned off in a delayed manner according to the second class of current parameters.
It should be noted that, the temperature of the refrigerating chamber is greater than the threshold value of the refrigerating temperature, and the temperature of the refrigerating chamber is less than the threshold value of the refrigerating opening temperature, which means that the temperature of the refrigerating chamber is in the upper half area of the refrigerating closing temperature and the refrigerating opening temperature, and further refrigeration is needed to achieve the refrigerating closing temperature, the control device gives the refrigerating stop parameter a new value again, i.e. the refrigerating stop parameter is replaced by the second type current parameter, and the second type current parameter is greater than the first type current parameter, so that the compressor and the fan can work for a longer time. The second type of current sub-parameter is set by the control device according to the actual condition of the current refrigeration cycle, and the second type of current sub-parameter is larger than the freezing shutdown parameter, and the LD is known according to the formula off (freeze off temperature) will become smaller.
After the control equipment sets the second type current sub-parameters, the compressor and the fan are controlled according to the second type current sub-parameters until the shutdown condition of the second type current sub-parameters is reached.
In one example, as shown in fig. 3, the step of controlling the compressor and the fan to be turned off in a delayed manner according to the second type of current sub-parameter includes the steps of:
step S310, updating the freezing closing temperature according to the second class current parameter.
In step S320, if the temperature of the freezing chamber is less than or equal to the updated freezing closing temperature, the compressor and the fan are controlled to be turned off.
The freeze off temperature is updated based on the following formula:
LD off (freeze off temperature) =ld on -LD gx2 (second class current sub-parameter)/2.
Therefore, the updated freezing closing temperature is smaller than the freezing closing temperature before updating, and the compressor and the fan need to continuously work the temperature of the freezing chamber to meet the condition of being smaller than or equal to the freezing closing temperature, so that compared with the normal shutdown condition, the compressor and the fan are delayed to be closed, and synchronous refrigeration of the freezing chamber and the refrigerating chamber is realized.
In each embodiment of the refrigerator refrigeration control method, when the compressor and the fan are in an on state and the temperature of the freezing chamber is detected to be less than or equal to the freezing closing temperature, the running state of the air door is detected; if the running state of the air door is an opening state, acquiring the temperature of the refrigerating chamber; if the temperature of the refrigerating chamber is larger than the refrigerating closing temperature and the temperature of the refrigerating chamber is smaller than the refrigerating temperature threshold, updating the refrigerating stop parameter to be a first-class current parameter; according to the first class of current parameters, the compressor and the fan are controlled to be delayed to be closed, when the freezing chamber reaches a closing condition smaller than or equal to the freezing closing temperature, the air door is detected to be in an open state to confirm that the refrigerating chamber needs to be refrigerated, and when the temperature of the refrigerating chamber is detected to be larger than the freezing closing temperature and smaller than a refrigerating temperature threshold value, the freezing shutdown parameters are updated to control the compressor and the fan to be delayed to be closed, so that the freezing chamber and the refrigerating chamber are synchronously refrigerated, the freezing chamber and the refrigerating chamber are prevented from being respectively opened for refrigeration, the power consumption of the refrigerator is reduced, and the service life of the refrigerator is prolonged.
In one embodiment, as shown in fig. 4, there is also provided a refrigeration control method of a refrigerator, including the steps of:
in step S410, if the temperature of the refrigerating chamber is detected to be greater than or equal to the refrigerating start temperature, the operation state of the compressor is detected.
The control device detects the temperature of the refrigerating chamber through a temperature sensor built in the refrigerating chamber, and when judging that the temperature of the refrigerating chamber is greater than or equal to the refrigeration opening temperature, the control device indicates that the refrigerating chamber needs to be refrigerated. In the conventional technology, when the temperature of the refrigerating chamber is greater than or equal to the refrigerating opening temperature, the fan and the air door are opened, and the refrigerating chamber begins to refrigerate; and when the temperature of the refrigerating chamber is less than or equal to the refrigerating closing temperature, closing the fan and the air door, and stopping refrigerating the refrigerating chamber. In the application, the traditional control logic is changed, and when the temperature of the refrigerating chamber is detected to be greater than or equal to the refrigerating start temperature, the refrigerating is not directly started, but the running state of the compressor is detected. Wherein detecting the operating condition of the compressor includes an on condition and an off condition. The refrigerating opening temperature is the starting point for judging the opening of the fan and the air door, namely the upper limit temperature which is selected by the control equipment near the set temperature and is larger than the set temperature is achieved, the refrigerating closing temperature is the stopping point for judging the closing of the fan and the air door, namely the lower limit temperature which is selected by the control equipment near the set temperature and is smaller than the set temperature is achieved.
In one example, the refrigeration on temperature and the refrigeration off temperature are obtained based on the following formulas:
LC on (refrigeration on temperature) =set temperature+lc d1 (refrigeration on parameters)/2.
LC off (refrigeration off temperature) =lc on -LC d2 (refrigerated shutdown parameter)/2.
In the above formula, the refrigeration start-up parameter is used for setting the refrigeration start-up temperature, and the refrigeration stop parameter is used for setting the refrigeration stop temperature.
The refrigerating chamber needs to be closed for refrigeration, and the refrigerating chamber is judged by the following conditions: and if the temperature of the refrigerating chamber is detected to be less than or equal to the refrigerating closing temperature, controlling the fan and the air door to be closed.
Step S420, if the running state of the compressor is the off state, updating the refrigeration starting parameter; the updated refrigeration starting-up parameter is greater than the refrigeration starting-up parameter.
It should be noted that, when the operation state of the compressor is detected to be the closed state, it is described that the freezing chamber is not in the refrigeration connection pipe, in order to ensure that the refrigerating chamber can synchronously refrigerate with the freezing chamber, the control device updates the refrigeration starting parameter, and the control device updates the refrigeration starting parameter in real time according to the actual condition of the current refrigeration cycle, so as to achieve the effect of delayed refrigeration of the refrigerating chamber, the updated refrigeration starting parameter is greater than the refrigeration starting parameter, and the refrigeration starting temperature is about to be increased.
In another way of judging logic, as shown in fig. 4, if the temperature of the refrigerating chamber is detected to be greater than or equal to the refrigerating start temperature, the step of detecting the operation state of the compressor includes the steps of: and if the running state of the compressor is an opening state, controlling the opening of the fan and the air door. That is, when the operation state of the compressor is detected to be an on state, which indicates that the freezing chamber is refrigerating, the fan and the air door can be immediately opened to synchronously cool the refrigerating chamber and the freezing chamber.
Step S430, controlling the delay opening of the fan and the air door according to the updated refrigeration starting parameters.
After updating the refrigeration starting parameters, the control device controls the fan and the air door according to the updated refrigeration starting parameters until the starting conditions of the updated refrigeration starting parameters are reached.
In one example, as shown in fig. 5, the step of controlling the fan and the damper to be opened in a delayed manner according to the updated refrigeration start-up parameter includes the steps of:
step S510, updating the refrigeration starting temperature according to the updated refrigeration starting parameters.
And step S520, if the temperature of the refrigerating chamber is greater than or equal to the updated refrigerating opening temperature, controlling the opening of the fan and the air door.
The freeze off temperature is updated based on the following formula:
LC on (refrigeration on temperature) =setConstant temperature +LC gx (updated refrigeration on parameters)/2.
Therefore, the updated refrigeration opening temperature is larger than the refrigeration opening temperature before updating, and the refrigeration opening condition is widened, so that compared with the normal starting condition, the fan and the air door are delayed to be opened, and synchronous refrigeration of the freezing chamber and the refrigeration chamber is realized.
In each embodiment of the refrigeration control method of the refrigerator, if the temperature of the refrigerating chamber is detected to be greater than or equal to the refrigeration starting temperature, the running state of the compressor is detected; if the running state of the compressor is in a closed state, updating the refrigeration starting parameters; according to the updated refrigeration starting parameters, the air door is controlled to be opened in a delayed manner, refrigeration is needed in the detection refrigerating chamber, and the refrigerating chamber is confirmed not to be in a refrigeration stage temporarily by detecting that the compressor is in a closed state, so that the refrigeration starting parameters are updated to control the air door to be opened in a delayed manner, refrigeration of the refrigerating chamber is waited, refrigeration synchronization of the refrigerating chamber and the refrigerating chamber is achieved, the refrigerating chamber and the refrigerating chamber are prevented from being opened for refrigeration respectively, power consumption of the refrigerator is reduced, and service life of the refrigerator is prolonged.
It should be understood that, although the steps in the flowcharts of fig. 1-5 are shown in order as indicated by the arrows, these steps are not necessarily performed in order as indicated by the arrows. The steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders. Moreover, at least some of the steps in fig. 1-5 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily occur sequentially, but may be performed alternately or alternately with at least a portion of the sub-steps or stages of other steps or steps.
