Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present 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, a refrigeration control method of the refrigerator is provided, which includes the following steps:
and step S110, detecting the operation state of the air door when the compressor and the fan are in the opening state and the temperature of the freezing chamber is detected to be less than or equal to the freezing closing temperature.
The refrigerator refrigeration control method is implemented by the control device of the refrigerator. The refrigerator comprises a freezing chamber and a refrigerating chamber, when the freezing chamber needs to refrigerate, the control device controls the compressor and the fan to be opened, and when the refrigerating chamber needs to refrigerate, the control device controls the fan and the air door to be opened, so that the control device can detect the running conditions of relevant devices of the refrigerator to judge whether the freezing chamber is in a refrigerating stage or not and whether the refrigerating chamber is in a refrigerating stage or not. In the steps of the refrigeration control method of the refrigerator, when the compressor and the fan are in the opening state, the refrigerating chamber is in the refrigeration stage.
When the freezing chamber is in a refrigeration stage, the control device detects the temperature of the freezing chamber through a built-in temperature sensor of the freezing chamber, and the temperature of the freezing chamber is a basis for judging whether the compressor and the fan are started or closed. In the conventional technology, when the temperature of a freezing chamber is greater than or equal to a freezing starting temperature, a compressor and a fan are started, 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. And in this application, change traditional control logic, freezing temperature is less than or equal to freezing closing temperature, after reaching the condition of closing compressor and fan, directly do not close compressor and fan, but detect the running state of air door. The freezing closing temperature is a stop point for judging and closing the compressor and the fan, namely the freezing chamber reaches the set temperature, and the lower limit temperature which is smaller than the set temperature and is selected by the control equipment near the set temperature. The freezing starting temperature is the starting point for judging and starting the compressor and the fan, namely the freezing chamber reaches the set temperature, and the control equipment selects the upper limit temperature which is higher than the set temperature near the set temperature.
In one example, the freeze on temperature and the freeze off temperature are obtained based on the following equations:
LDon(freezing start temperature) ═ set temperature + LDd1(freezing startup parameters)/2.
LDoff(freezing off temperature) ═ LDon-LDd2(freezing shutdown parameters)/2.
In the above formula, the freezing startup parameter is used to set the freezing startup temperature, and the freezing shutdown parameter is used to set the freezing shutdown temperature.
The refrigerating chamber needs to be started for refrigeration and is judged by the following conditions: and if the detected temperature of the freezing chamber is greater than or equal to the freezing opening temperature, controlling the compressor and the fan to be opened.
In step S120, if the operation state of the damper is the open state, the temperature of the refrigerating chamber is acquired.
The running state of air door is the open mode, explain the reefer needs refrigeration, if at this moment because the freezer reaches the condition of stopping refrigeration, and direct closing compressor and fan, stagger when the refrigeration stage of freezer and reefer will lead to refrigerator power consumptive height, this application is in order to solve this problem, when the running state of air door is the open mode, controlgear measures the reefer temperature through built-in and the temperature sensor of reefer to judge the relation between reefer temperature and the cold-stored close temperature and the cold-stored temperature threshold value. The refrigeration closing temperature is a stop point for judging and closing the fan and the air door, namely the refrigeration chamber reaches the set temperature, and the lower limit temperature which is lower than the set temperature and is selected by the control equipment near the set temperature. The refrigerating opening temperature is the starting point for judging and opening the fan and the air door, namely the refrigerating chamber reaches the set temperature, and the control equipment selects the upper limit temperature which is higher than the set temperature near the set temperature.
In one example, the refrigeration turn-on temperature and the refrigeration turn-off temperature are obtained based on the following equations:
LCon(refrigeration opening temperature) ═ setting temperature + LCd1(refrigeration startup parameter)/2.
LCoff(refrigeration shutdown temperature) ═ LCon-LCd2(refrigeration shutdown parameters)/2.
In the above formula, the refrigeration startup parameter is used to set the refrigeration startup temperature, and the refrigeration shutdown parameter is used to set the refrigeration shutdown 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 and less than the refrigeration opening temperature. In one example, the refrigeration temperature threshold is obtained according to the following steps: acquiring a difference value between a refrigeration opening temperature and a refrigeration closing temperature; and acquiring a sum of the difference value of one half and the refrigeration closing temperature, and taking the sum as a refrigeration temperature threshold value.
In one example, the refrigeration temperature threshold is obtained based on the following equation:
LCtest(refrigerating temperature threshold) ═ LCon-LCoff)/2-LCoff。
In another logic, as shown in fig. 1, if the freezing chamber temperature is detected to be less than or equal to the freezing closing temperature, the step of detecting the operation state of the damper includes the following steps:
and step S150, if the operation state of the air door is a closed state, controlling the compressor and the fan to be closed.
It should be noted that, the operation state of the damper is detected to be a closed state, which indicates that the refrigerating chamber does not need to be refrigerated, and at this time, the compressor and the fan are directly controlled to be closed when the freezing chamber also reaches the shutdown condition.
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 value, updating the freezing shutdown parameter as a first type of current parameter; the first type of current time parameter is greater than the freezing shutdown parameter; the refrigeration temperature threshold is greater than the refrigeration closing temperature, and the refrigeration temperature threshold is less than the refrigeration opening 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 value, the lower half area of the temperature 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 equipment gives a new value to the freezing shutdown parameter again, namely the freezing shutdown parameter is replaced by a first type of current parameter, it needs to be indicated that the first type of current parameter is set by the control equipment according to the actual condition of the current refrigerating cycle, the first type of current parameter is greater than the freezing shutdown parameter, and the refrigerating cycle is controlled according to the first type of current parameter and the second type of current parameterFrom the above formula, LDoffThe (freeze off temperature) becomes small.
And step S140, controlling the delayed closing of the compressor and the fan according to the first type current parameter.
It should be noted that, after the control device sets the first type of current parameter, the compressor and the fan are controlled according to the first type of current parameter until the shutdown condition of the first type of current parameter is reached.
In one example, as shown in fig. 2, the step of controlling the delayed turning off of the compressor and the fan according to the first type of current secondary parameter includes the steps of:
step S210, updating the freezing shutdown temperature according to the first type of current parameter.
And step S220, if the temperature of the freezing chamber is less than or equal to the updated freezing closing temperature, controlling the compressor and the fan to be closed.
Note that the freeze shutdown temperature is updated based on the following equation:
LDoff(freezing off temperature) ═ LDon-LDgx1(current secondary parameter of first class)/2.
Therefore, the updated freezing closing temperature is lower than the freezing closing temperature before updating, and the compressor and the fan need to work continuously until the temperature of the freezing chamber meets the condition of being lower than or equal to the freezing closing temperature, so that the compressor and the fan are closed in a delayed mode compared with the normal shutdown condition, and synchronous refrigeration of the freezing chamber and the refrigerating chamber is realized.
In another logic, as shown in fig. 1, the step of obtaining the temperature of the refrigerating chamber after the step of obtaining the temperature of the refrigerating chamber if the operation state of the damper is the open state includes the steps of:
step S160, if the temperature of the refrigerating chamber is greater than the refrigerating temperature threshold value and the temperature of the refrigerating chamber is less than the refrigerating starting temperature, updating the freezing shutdown parameter to be a second type current parameter; the second type of current time parameter is greater than the freezing shutdown parameter; the second type of current secondary parameter is greater than the first type of current secondary parameter.
And S170, controlling the delayed closing of the compressor and the fan according to the second type current parameter.
It should be noted that the temperature of the refrigerating chamber is greater than the refrigerating temperature threshold value, and the temperature of the refrigerating chamber is less than the refrigerating opening temperature, which indicates that the temperature of the refrigerating chamber is in the upper half area of the refrigerating closing temperature and the refrigerating opening temperature, in order to achieve the refrigerating closing temperature, further refrigeration is required, the control equipment gives a new value to the freezing shutdown parameter again, that is, the freezing shutdown 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 kind of current time parameter is set by the control device according to the actual condition of the current time refrigeration cycle, the second kind of current time parameter is larger than the freezing shutdown parameter, and the LD can be known according to the formulaoffThe (freeze off temperature) becomes small.
And after the control equipment sets the second type current parameter, controlling the compressor and the fan according to the second type current parameter until the shutdown condition of the second type current parameter is reached.
In one example, as shown in fig. 3, the step of controlling the delayed turning off of the compressor and the fan according to the second type of current secondary parameter includes the steps of:
step S310, the freezing closing temperature is updated according to the second type current parameter.
And step S320, if the temperature of the freezing chamber is less than or equal to the updated freezing closing temperature, controlling the compressor and the fan to be closed.
Note that the freeze shutdown temperature is updated based on the following equation:
LDoff(freezing off temperature) ═ LDon-LDgx2(second type current sub-parameter)/2.
Therefore, the updated freezing closing temperature is lower than the freezing closing temperature before updating, and the compressor and the fan need to work continuously until the temperature of the freezing chamber meets the condition of being lower than or equal to the freezing closing temperature, so that the compressor and the fan are closed in a delayed mode compared with the normal shutdown condition, and synchronous refrigeration of the freezing chamber and the refrigerating chamber is realized.
In each embodiment of the refrigeration control method of the refrigerator, when the compressor and the fan are in an opening state and the temperature of the freezing chamber is detected to be less than or equal to the freezing closing temperature, the operation 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 higher than the refrigerating closing temperature and the temperature of the refrigerating chamber is lower than the refrigerating temperature threshold value, updating the freezing shutdown parameter as a first type of current secondary parameter; according to the first type of current parameters, the delayed closing of the compressor and the fan is controlled, when the freezing chamber reaches a closing condition that the freezing closing temperature is less than or equal to the freezing closing temperature, the air door is detected to be in an opening state to confirm that the refrigerating chamber needs to be refrigerated, and when the temperature of the refrigerating chamber is detected to be greater than the freezing closing temperature and less than the refrigerating temperature threshold value, the freezing shutdown parameters are updated to control the delayed closing of the compressor and the fan, so that the refrigeration of the freezing chamber and the refrigerating chamber is synchronous, 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 it is detected that the temperature of the refrigerating chamber is 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 which is arranged in the refrigerating chamber and the refrigerating chamber, and the refrigerating chamber needs to be refrigerated when the control device judges that the temperature of the refrigerating chamber is greater than or equal to the refrigerating starting temperature. In the traditional technology, when the temperature of the refrigerating chamber is greater than or equal to the refrigerating opening temperature, a fan and an air door are opened, and the refrigerating chamber starts 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 opening temperature, the refrigeration is not directly started, but the running state of the compressor is detected. The running state of the compressor is detected to comprise an opening state and a closing state. The refrigerating opening temperature is a starting point for judging and opening the fan and the air door, namely the refrigerating chamber reaches a set temperature, the upper limit temperature which is larger than the set temperature and is selected by the control equipment near the set temperature is set, the refrigerating closing temperature is a stopping point for judging and closing the fan and the air door, namely the refrigerating chamber reaches the set temperature, and the lower limit temperature which is smaller than the set temperature and is selected by the control equipment near the set temperature is set by the control equipment.
In one example, the refrigeration turn-on temperature and the refrigeration turn-off temperature are obtained based on the following equations:
LCon(refrigeration opening temperature) ═ setting temperature + LCd1(refrigeration startup parameter)/2.
LCoff(refrigeration shutdown temperature) ═ LCon-LCd2(refrigeration shutdown parameters)/2.
In the above formula, the refrigeration startup parameter is used to set the refrigeration startup temperature, and the refrigeration shutdown parameter is used to set the refrigeration shutdown temperature.
The refrigerating chamber needs to be shut down for refrigeration, and is judged by the following conditions: and if the detected temperature of the refrigerating chamber is 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 closing state, updating the refrigeration starting parameter; the updated refrigeration startup parameter is greater than the refrigeration startup parameter.
It should be noted that, when the operation state of the compressor is detected to be the off state, it is indicated that the freezing chamber is not located in the refrigeration connecting pipe, in order to ensure that the refrigerating chamber and the freezing chamber can be synchronously refrigerated, the control device controls and updates the refrigeration starting parameter, and the control device performs real-time updating according to the actual situation of the current refrigeration cycle, in order to achieve the effect of delaying refrigeration of the refrigerating chamber, the updated refrigeration starting parameter is greater than the refrigeration starting parameter, that is, the refrigeration starting temperature is increased.
In another logic, as shown in fig. 4, if it is detected that the temperature of the refrigerating chamber is greater than or equal to the refrigerating opening temperature, the step of detecting the operating state of the compressor includes the following steps: and if the running state of the compressor is the opening state, controlling the fan and the air door to be opened. The running state of the compressor is detected to be an opening state, which indicates that the freezing chamber is refrigerating, and the fan and the air door can be immediately opened to synchronously refrigerate the refrigerating chamber and the freezing chamber.
And step S430, controlling the fan and the damper to be opened in a delayed mode according to the updated refrigeration starting-up parameters.
It should be noted that, after the refrigeration startup parameter is updated, the control device controls the fan and the air door according to the updated refrigeration startup parameter until the startup condition of the updated refrigeration startup parameter is 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 startup parameter includes the steps of:
step S510, updating the refrigeration start temperature according to the updated refrigeration start parameter.
And step S520, if the temperature of the refrigerating chamber is greater than or equal to the updated refrigerating opening temperature, controlling the fan and the air door to be opened.
Note that the freeze shutdown temperature is updated based on the following equation:
LCon(refrigeration opening temperature) ═ setting temperature + LCgx(updated refrigeration startup parameters)/2.
Therefore, the updated refrigeration opening temperature is greater 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 opened in a delayed manner, and the synchronous refrigeration of the freezing chamber and the refrigerating 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 refrigerating starting temperature, the running state of the compressor is detected; if the running state of the compressor is the closing state, updating the refrigeration starting-up parameters; the air door is controlled to be opened in a delayed mode according to the updated refrigeration starting parameters, refrigeration in the refrigerating chamber is detected, the refrigerating chamber is confirmed not to be in the refrigeration stage temporarily by detecting the closing state of the compressor, and therefore the refrigeration starting parameters are updated to control the air door to be opened in a delayed mode to wait for refrigeration of the refrigerating chamber, refrigeration of the refrigerating chamber and the refrigerating chamber is enabled to be synchronous, the refrigerating chamber and the refrigerating chamber are prevented from being opened and refrigerated respectively, power consumption of the refrigerator is reduced, and the service life of the refrigerator is prolonged.
It should be understood that although the various steps in the flow charts of fig. 1-5 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-5 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
