Description

AI Mode Control Method of Air Curtain Refrigerator

The present invention relates to a method for controlling an artificial intelligence mode of an air curtain refrigerator, and in particular, when the air curtain refrigerator is set to an artificial intelligence mode, a refrigerator and a freezer compartment are operated by operating an air curtain fan for a predetermined time while operating in a medium mode at a time when doors are frequently opened and closed. It relates to an AI mode control method of an air curtain refrigerator to maintain a constant temperature.

In general, the air curtain refrigerator has a slit-shaped air outlet on the front of the refrigerating chamber, and by spraying a strong plane cold air through this air outlet through the operation of the air curtain fan, it recovers a large number of them and blocks the inflow of outside air, thereby raising the internal temperature. It is a refrigerator to suppress. In general, a conventional refrigerator freely flows into the inside of the refrigerator due to the buoyancy caused by the difference in density when the door is opened to increase the temperature of the stored food. Therefore, the air curtain refrigerator developed to prevent such a phenomenon of the existing refrigerator, that is, the phenomenon that outside air flows when opening the refrigerating compartment door, is shown inside the upper part of the refrigerating compartment 76 when the door of the refrigerating compartment 76 is opened as shown in FIG. 1. The air generated as the installed air curtain fan 73 operates is sprayed in the form of a strong flat jet of about 5 m / sec or more through the air ejection opening 74 installed in the upper front. At this time, the multi-duct 77 is formed in the upper, middle and lower portion of the refrigerating chamber 76, the multi-duct inlet is formed in the refrigerating chamber by maintaining the L-shaped flow without the flat jet is distributed to the lower end of the refrigerating chamber by a properly adjusted suction force (76) Opening the door prevents the inflow of outside air. In addition, the air curtain refrigerator has a large amount generated by operating the air curtain fan 73 for a predetermined time even after the refrigerating compartment 76 door is closed in order to prevent the temperature from rising due to food input after opening the refrigerating compartment 76 door. By rapidly rotating the entire air volume in the air volume, the refrigerating chamber 76 is rapidly cooled as well as uniformly cooled.

In addition, the air curtain refrigerator has an artificial intelligence mode in addition to the rapid refrigeration and rapid refrigeration mode, and when the user sets the artificial intelligence mode, the refrigerator stores the number of door opening / closing every two hours for eight days and the refrigerator operates. During operation, the refrigerator operates in the strong mode when the door is frequently opened and closed while driving in the medium mode. Here, the refrigerator usually has a power saving mode, a weak mode, a medium mode, and a strong mode, so that the user can set it arbitrarily according to their needs. By operating in such a set mode it is possible to cool the refrigerator.

That is, looking at the method of measuring the number of times according to the door opening and closing according to the artificial intelligence mode as follows.

That is, as shown in Table 1, by checking the opening of the door at intervals of two hours as a cumulative time, if the door is opened for 30 seconds or more, it is checked as one time of opening the door. Therefore, if the number of times the door is opened more than 30 times in 8 days more than 6 times, the refrigerator is operated in the strong mode during the time period, and less than 5 times the door is operated in the medium mode during the time period.

On the other hand, as shown in the control method of the conventional refrigerator performing the artificial intelligence mode as shown in FIG. 2, the initialization state (S21) to which the driving power is applied to the refrigerator proceeds to the data storage step (S22). Then, the data storage step (S22) checks and stores the number of door opening for each time period for 8 days and proceeds to the refrigerator normal operation step (S23). Then, in the normal refrigerator operation step (S23), the temperature of the refrigerating compartment and the freezing compartment is properly maintained by the set program, and the process proceeds to the artificial intelligence mode setting determination step (S24). At this time, if it is determined in the artificial intelligence mode setting determination step (S24) that the artificial intelligence mode is set during operation of the refrigerator, the process proceeds to the current time checking step (S25). Therefore, the current time checking step (S25) is to check the current time and proceed to the door opening and closing frequency determination step (S26). At this time, when the door opening and closing frequent time determination step (S26) is determined as the frequent opening and closing of the door based on the data stored in the current refrigerator operating time is to proceed to the refrigerator strong mode operation step (S27). Therefore, in the refrigerator strong mode operation step (S27), the refrigerator compartment and the freezer compartment are operated to maintain the temperature corresponding to the strong mode, thereby terminating the present loop.

On the other hand, if it is determined that the door opening and closing frequent time determination step (S26) is determined that the opening and closing of the door is not a frequent time by the data stored in the current refrigerator operation time proceeds to the refrigerator mode operation step (S30). Therefore, in the refrigerator mode operation step (S30), the loop is terminated while the refrigerator compartment and the freezer compartment are operated to maintain the temperature corresponding to the medium mode. When it is determined that the artificial intelligence mode is not set as determined by the artificial intelligence mode setting determination step (S24), the operation returns to the refrigerator normal operation step (S23) to repeat the loop.

That is, if the artificial intelligence mode is set during the operation of the refrigerator as described above, the temperature of the refrigerating chamber is maintained in the strong mode during the frequent door times.

However, according to the artificial intelligence mode of the air curtain refrigerator, that is, the number of door opening / closing every 2 hours and stored for 8 days, it is set to operate in the medium mode in the normal time zone and also in the time zone in which the door is frequently opened and closed. When operating in the strong mode, but the continuous operation in the AI mode, the cold and low temperature due to the supply of cold air in the refrigerator compartment and the freezer had a problem in food storage.

Accordingly, the present invention has been made to solve the above problems, and in the artificial intelligence mode of the air curtain refrigerator, the door is operated in the medium mode during frequent times of the door, and at the same time, the air curtain fan is operated for a predetermined time, as well as in the cold room at a high speed. It is an object of the present invention to provide a method of controlling the AI mode of an air curtain refrigerator capable of keeping the whole temperature of the temperature constant.

On the other hand, the present invention for achieving the above object is a refrigerator normal operation step for performing the operation for maintaining the proper temperature of the refrigerating compartment and the freezing chamber by the set mode, and during the operation in the refrigerator normal operation step for opening and closing the door by time zone for a certain time The artificial intelligence data storage step of storing the number of times according to the data, and the artificial intelligence mode is set in the state in which the data is stored by the operation of the refrigerator in the artificial intelligence data storing step to determine whether the door opening or closing frequently according to the current refrigerator operation time. Judging from the opening / closing judging stage and this door opening / closing judging stage, it is judged that the door opening and closing is frequent based on the stored data of the current refrigerator operation time, which operates the refrigerating chamber in the medium mode and simultaneously operates the air curtain fan for the set time. And air curtain fan operation step, the door opening and closing number Is determined by only the process result is not a frequent time basis of the door opening and closing of the current time stored in the refrigerator operation data determined in characterized by comprising the step of operating jungmo de jungmo draw operating a fresh food compartment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, the configuration of the air curtain refrigerator according to the present invention, as shown in Figure 3 is largely installed in the refrigerator, respectively, the sensor unit for detecting the state of the refrigerator compartment and the refrigerator and output a predetermined signal, respectively from the sensor unit It consists of a microcomputer that receives the detected signal to perform the overall control of the refrigerator, and various driving units operated by receiving a driving power according to the control signal of the microcomputer.

The microcomputer 1 is connected to a mode setting unit 2 for setting a rapid function and an artificial intelligence mode of the refrigerator.

Here, the sensor unit is installed in the freezer compartment of the F (F) sensor (5) for sensing the temperature, the egg (R) sensor (4) installed in the upper right of the refrigerating compartment for detecting the temperature in the refrigerator, and the refrigerator compartment and the freezer The door detection unit 3 detects a signal according to the door opening.

In addition, the driving unit includes a compressor (9) operating as a refrigeration cycle according to the control signal of the microcomputer (1), and an F fan (operating to maintain the freezing chamber at an appropriate temperature by absorbing the internal temperature of the cooler according to the operation of the compressor 9). 7), an air curtain fan 6 operating with a constant drive power output according to the opening of the door of the refrigerating compartment, an al fan 8 for blowing constant cold air to the refrigerating compartment, and an F fan for blowing constant cold air to the freezing compartment. It consists of (7).

On the other hand, look at the operation of the air curtain refrigerator having such a configuration as follows.

First, as the power of the refrigerator is applied, the compressor 9 performs an operation by a refrigeration cycle, and thus the cooler not shown absorbs heat in the refrigerator. In other words, the F fan 7 and the al fan 8 are operated in a state of being operated in this manner, and the air cooled by the cooler is supplied to each freezing compartment and the refrigerating compartment. At this time, the cold room supplied to the freezer and the refrigerating chamber is kept at -18 ° C so that food can be stored in a frozen state for a long time, and the refrigerating chamber is stored at 0 ° C, where meat, fish and vegetables can be stored in a refrigerated state. It is maintained at 9 ℃.

On the other hand, the user to set the artificial intelligence mode through the mode setting unit (2) to the refrigerator to operate as described above. Then, the microcomputer 1 stores 8 days of data regarding the number of door opening and closing times in each time zone, and thus, the microcomputer 1 operates the refrigerating chamber and the freezing chamber according to the data. In other words, if the current refrigerator operation time is determined to be a door opening and closing frequently, the operation in the medium mode will eventually maintain the set temperature according to the medium mode. In addition, if the current time corresponds to a time when the door is frequently opened and closed while the refrigerator is operating in the medium mode, the refrigerating chamber maintains the temperature corresponding to the medium mode by the operation of the Al fan 8, and also the control signal of the microcomputer 1 As a result, the air curtain fan 6 is driven for a predetermined time, so that the temperature of the refrigerating compartment is strengthened to some extent and the refrigerating compartment temperature is rapidly cooled.

On the other hand, the artificial intelligence mode control method of the air curtain refrigerator according to the present invention as shown in Figure 4, first, the initial state (S1) applying the driving power of the refrigerator proceeds to the refrigerator normal operation step (S2). . In this refrigerator normal operation step (S2) it performs the operation for maintaining the proper temperature of the refrigerating chamber and the freezing chamber by the set mode, and proceeds to the artificial intelligence data storage step (S3). Then, in the artificial intelligence data storage step (S3), the data is stored according to the opening and closing of the door during the operation of the refrigerator for 8 days, and the process proceeds to the artificial intelligence mode setting determination step (S4). At this time, if it is determined in the artificial intelligence mode setting determination step (S4) that the artificial intelligence mode is set according to a specific key input, the operation time is checked (S5). Therefore, the operation time checking step (S5) is to check the current operating time of the refrigerator and proceeds to the door opening and closing frequent time determination step (S6). Therefore, if it is determined that the door opening and closing time of the refrigerator is frequent based on the data set in the present time, as determined by the door opening / closing frequency determining step (S6), the process proceeds to the first refrigerator mode operation step (S7). Then, in the first cold room operation mode (S7), the temperature of the refrigerating chamber is operated to be maintained at a temperature corresponding to the set medium mode, and the air curtain fan operation step (S8) is performed. Thus, in the air curtain fan operation step S8, the air curtain fan is operated in the refrigerating chamber operating in the medium mode, and the flow proceeds to the set time elapse determination step S9. Then, if it is determined in the set time elapsed judging step S9 that the set time has not elapsed, the process returns to the air curtain fan operation step S8 to repeat the loop, and further, the set time elapsed judging step S9. If it is determined that the set time has elapsed, the normal operation of the refrigerator is performed and the loop ends.

On the other hand, if it is determined in the door opening and closing frequent time determination step (S6) that the current time is not the time zone frequent the door opening and closing of the refrigerator, the process proceeds to the second refrigerator mode operation step (S10). Therefore, in the second cold room operation mode (S10), the refrigerating chamber is maintained at a temperature corresponding to the medium mode, and the loop returns to the current time checking step (S10). In addition, if it is determined in the artificial intelligence mode setting determination step (S4) that the artificial intelligence mode of the refrigerator in operation is not set, the operation returns to the refrigerator normal operation step (S2) to repeat the loop.

As described above, the present invention operates the refrigerator in a medium mode when the door opening and closing frequently occurs during the operation of the refrigerator, and operates the air curtain fan for a predetermined time, thereby reinforcing the temperature of the refrigerator compartment without fear of overcooling. By maintaining the temperature distribution in the refrigerator compartment uniformly, there is an effect that can double the freshness and storage capacity of the stored food.
