The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of a refrigerator, a control apparatus of a refrigerator, a control system of a refrigerator, and a refrigerator according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of a refrigerator according to an embodiment of the present invention.
In the embodiment of the invention, the refrigerator at least comprises a compressor and an ice-making chamber arranged in a refrigerating chamber or a freezing chamber, wherein the refrigerating chamber and the freezing chamber are cooled by a system refrigerating system, the system refrigerating system at least comprises a system evaporator, a system fan and the like, the ice-making chamber is cooled by an independent ice-making refrigerating system, and the ice-making refrigerating system at least comprises an ice-making machine, a refrigerating fan, a refrigerating evaporator and the like. Wherein, the system evaporator and the refrigeration evaporator are connected in series or in parallel.
As shown in fig. 1, the method for controlling a refrigerator according to an embodiment of the present invention includes the steps of:
and S1, detecting and confirming that the accumulated running time of the compressor is at least an operating time threshold value, and the ice maker is in a working state currently, and controlling the ice maker to perform defrosting operation after the current ice making period is finished, wherein the operating time threshold value is the time difference between the defrosting period of the refrigerator and the ice making period of the ice maker.
According to one embodiment of the invention, the ice maker is controlled to perform defrosting operation after the current ice making period is finished, and the defrosting operation comprises the following steps: and detecting and confirming the end of the current ice making period, and controlling the ice making machine to perform defrosting operation.
Specifically, if the refrigerator does not judge the current working state of the ice maker, the defrosting operation is performed only by depending on the accumulated running time of the compressor or other additional conditions, and if the accumulated running time of the compressor reaches a preset time, the defrosting operation is started, so that a defrosting starting point may be located in the latter half of an ice making process of the ice maker, and at this time, the temperature and power curve of the ice making chamber is as shown in fig. 2, which may cause the temperature of the ice making chamber to rise greatly, normal ice making cannot be continued in the period, the ice making period is lengthened, the ice making amount is reduced, and the energy consumption is increased.
If the current working state of the ice machine is judged before defrosting, when the ice machine is in the working state, defrosting operation is delayed, and the delay can prolong the working time of the compressor, so that the risk of frost blockage of the evaporator is increased. When frost blockage occurs to the evaporator, the temperature and power curves of the ice making chamber are as shown in fig. 3 and 4, and are divided into two cases: in the first situation, after the evaporator is frosted and blocked, as shown in fig. 3, the temperature of the ice making chamber slowly and finally stops decreasing, even slightly rises, in this situation, the closed loop of the refrigeration system is damaged, and the refrigerator cannot work normally; in the second case, when the evaporator is frost-blocked, as shown in fig. 4, the temperature of the ice-making chamber drops slowly and cannot reach the ice-shedding heating point, and when the ice-making time exceeds the ice-making period of the ice-making machine, the ice-making action is interrupted and the frost is removed, which results in complete waste of energy consumption in the ice-making period.
Therefore, in the embodiment of the invention, the working state of the ice maker is judged before defrosting, when the ice maker is currently in the working state, the accumulated running time of the compressor is obtained, the time difference between the defrosting period of the refrigerator and the ice making period of the ice maker is obtained and used as the running time threshold, if the accumulated running time of the compressor is at least (greater than or equal to) the running time threshold, whether the running time of the ice maker reaches the ice making period is judged in real time, and when the running time of the ice maker reaches the ice making period, namely the current ice making period is ended, the ice maker is controlled to carry out defrosting operation in advance, the temperature and power curve of the ice making chamber is shown in fig. 5, and in the state, the influence of defrosting of the ice making evaporator on normal ice making of the ice making chamber is minimum.
Further, the control method of the refrigerator further includes: detecting and confirming that the accumulated running time is at least a running time threshold value, and controlling the ice maker not to send out an ice making request when the ice maker is in a non-working state; and detecting and confirming that the accumulated running time reaches a defrosting period, and controlling the refrigerator to carry out defrosting operation.
Specifically, the refrigerator takes the accumulated running time of a compressor as a criterion, when the accumulated running time of the compressor is greater than or equal to T-T (wherein T is a defrosting period of the refrigerator, T is an ice making period of an ice making machine, and T-T is a running time threshold), the current working state of the ice making machine is judged, if the ice making machine is in the working state at the moment, whether the running time of the ice making machine reaches the ice making period of the ice making machine is continuously judged, namely whether the ice making period is finished is judged, if the ice making period is finished, a defrosting operation is carried out in advance, and if the ice making period is not finished, the ice making period is waited to finish the defrosting operation in; and if the ice maker is in a non-working state, inhibiting the ice maker from sending an ice making request, judging whether the accumulated operation time of the compressor reaches a refrigerator defrosting period T or not, if so, controlling the refrigerator to carry out defrosting operation, otherwise, continuously inhibiting the ice maker from sending the ice making request, and controlling the ice maker to carry out defrosting operation when waiting for the accumulated operation time of the compressor to reach the refrigerator defrosting period T. Therefore, the control method of the refrigerator can effectively avoid the adverse effect of defrosting on ice making of the ice making machine, effectively improve the ice making quantity and the ice making efficiency, reduce the energy consumption, shorten the ice making period and improve the product reliability.
In order to make the present invention more clear to those skilled in the art, as shown in fig. 6, a control method of a refrigerator according to an embodiment of the present invention includes the following steps:
s101, acquiring a time difference (T-T) between a defrosting period T of the refrigerator and an ice making period T of the ice maker.
S102, judging whether the accumulated running time of the compressor exceeds (T-T). If yes, go to step S103; if not, return to step S101.
And S103, judging whether the ice machine works or not. If yes, go to step S104; if not, step S105 is performed.
And S104, judging whether the ice making period is finished or not. If yes, go to step S107; if not, step S105 is performed.
And S105, inhibiting the ice maker from sending an ice making request.
And S106, judging whether the accumulated running time of the compressor reaches T or not. If so, step S107 is performed.
And S107, defrosting operation.
In summary, according to the control method of the refrigerator in the embodiment of the invention, when the accumulated operation time of the compressor is detected and confirmed to be at least the time difference between the defrosting cycle of the refrigerator and the ice making cycle of the ice maker, and the ice maker is currently in the working state, the ice maker is controlled to perform the defrosting operation after the current ice making cycle is ended. The method can avoid defrosting in the ice making period, thereby reducing the influence of defrosting on ice making of the ice maker, effectively improving the ice making efficiency and the ice making quantity of the ice maker, shortening the ice making period, reducing energy consumption and improving the reliability of products.
