Abstract

The invention provides a refrigerator control method and the refrigerator. Wherein, the control method includes: obtaining the time period when the refrigerator door is opened more than a preset threshold; obtaining the operating time of the refrigerator; judging whether the operating time is within the time period; if so, controlling the refrigerator to enter the door seal inflation delay mode. During the above time period, according to the habit of the user, the door will be opened and closed frequently. In order to reduce the times of inflating and deflating the sealed air bag, the refrigerator is controlled to enter the door seal inflated delay mode. In this mode, when the refrigerator detects the door closing signal, the air pump will not inflate the sealed airbag immediately, but will inflate the sealed airbag after a preset time interval. If the user opens the refrigerator door again within the preset time range of detecting the door closing signal, it is not necessary to inflate the airtight airbag. Such setting, on the one hand, reduces the number of times of filling and deflation of the airtight air bag, and simplifies the operation of the refrigerator; on the other hand, reduces the number of times of starting the air pump, and prolongs the service life of the air pump.

Description

Refrigerator control method and refrigerator

technical field

The invention relates to the field of refrigerators, in particular to a refrigerator control method and the refrigerator.

Background technique

The door seals used in refrigerators currently on the market generally use magnetic strips to close the cabinets. However, after the refrigerator has been used for a long time, a gap will appear between the door seal and the cabinet due to weakening of the magnetic strip or deformation of the door seal. Once the door body is not tightly sealed, the cold air inside the refrigerator will leak out, which will affect the refrigeration of the refrigerator and food preservation. At the same time, the leakage of cold air will increase the burden on the refrigeration system of the refrigerator and waste electricity.

In addition, the door seal will be compressed during the closing process of the existing refrigerator, and the air in the air bag may gradually leak, which may eventually cause the PVC or TPE door seal body and the magnetic strip to be squeezed together to form a structure close to solid. The door seal is changed from the thermal conductivity of air under ideal conditions to the solid thermal conductivity composed of PVC or TPE door seals and magnetic strips, and the thermal conductivity increases several times or even ten times. The heat insulation effect of the door seal is seriously reduced, which affects the refrigeration of the refrigerator and the preservation of food.

It should be noted that FIG. 1 shows a cross-sectional view of the door seal 100, and the door seal 100 has a certain length, so the above-mentioned expansion head 120, support column 140 and mounting base 130 can all be arranged along the length direction of the door seal 100. extend.

The airtight air bag 111 can be inflated or released with gas to adjust the size of the inflatable head 120 . According to the foregoing, the airtight airbag 111 is connected to the inner space of the expansion head 120 , therefore, the volume of the inflatable head 120 can increase during the process of inflating the airtight airbag 111 . In this embodiment, the thickness of the airbag wall of the expansion head 120 is smaller than the thickness of the airbag wall of the door seal 100 . Therefore, the airbag wall of the main body part of the door seal 100 can withstand the air pressure greater than that of the airbag wall of the inflatable head 120 . When the sealing airbag 111 is inflated, the volume of the sealing airbag 111 will not change greatly, but the volume of the expansion head 120 will rapidly expand. Preferably, the airbag wall of the circular surface structure 121 of the inflatable head 120 can be further thinner than the airbag wall of other parts of the inflatable head 120, so that the circular surface structure 121 of the inflatable head 120 can inflate more rapidly.

An installation groove 310 is provided on the peripheral edge of the door body 300 facing the box body 200 , and the installation seat 130 is snapped into the installation groove 310 to install the door seal 100 . A groove 210 is provided on the peripheral edge of the box body 200 facing the door body 300 , and the groove 210 cooperates to accommodate the expansion head 120 when the door body 300 is closed. Preferably, the shape of the groove 210 matches the shape of the expansion head 120 . The bottom of the groove 210 is also provided with a circular groove with a larger accommodating space to cooperate with the circular surface structure 121 for accommodating the expansion head 120 .

The door detection device 400 is used for generating a door opening signal or a door closing signal. In this embodiment, the door detection device 400 includes: a first detection device 410 and a second detection device 420 . The first detection device 410 is disposed at the handle of the door body 300 and is configured to generate a door opening signal when sensing that the door body 300 is being held. In this embodiment, as shown in FIG. 4 , the handle of the refrigerator is a depression disposed on the open side edge of the refrigerator door 300, and the first detection device 410 may be a sensor disposed inside the depression. When the user's hand reaches into the depression, The first detecting device 410 generates a door opening signal, indicating that the door body 300 is about to be opened. The second detection device 420 is arranged on the edge of the opening side of the door body 300 or is arranged on the edge of the opening side of the box body 200 facing the door body 300, and is configured to detect that the door touches the box body 200, Generate a door close signal. The second detection device 420 can also be a sensor, and when the door body 300 is completely closed, the second detection device 420 sends a door closing signal.

The air pump 500 is arranged on the door body 300, which is connected to the sealing air bag 111 through a pipeline, and is also electrically connected to the door body detection device 400, and is configured to deflate the sealing air bag 111 after receiving the door opening signal, and the sealing air bag releases air. After air, the door body 300 is easier to open. After receiving the door closing signal, inflate the airtight airbag 111, and after the airtight airbag 111 is filled with air, since the heat insulation effect of the air is stronger than that of the door seal strip, the heat insulation performance of the door seal 100 increases, and there is Good for refrigerator insulation.

The air pump 500 can be arranged on the door body 300. In this embodiment, as shown in FIG. 5 , the top surface of the door body 300 is provided with a cavity extending along the width direction of the door body 300, and the air pump 500 is arranged in the cavity. The air pump 500 is connected to the inside of the sealed air bag 111 through a pipeline, and is used to inflate or deflate the sealed air bag 111 . The above-mentioned door seal 100 is provided with an air delivery port, and the air pump 500 is connected to the air delivery port through a pipeline for inflating or deflating the airtight air bag 111 . The air pump 500 is a miniature air pump 500, and the power can be between 2W-6W. The air pump 500 is also electrically connected to the door detection device 400 for receiving the door opening signal or the door closing signal from the door detection device 400 . After receiving the door opening signal, the air pump 500 deflates the airtight air bag 111 so that the expansion head 120 shrinks. When the volume of the expansion head 120 is smaller than the volume of the groove 210 , the expansion head 120 can be pulled away from the groove 210 so that the door seal 100 is separated from the box body 200 . After receiving the door closing signal, the air pump 500 inflates the sealed air bag 111 to increase the volume of the inflatable head 120 and make the air bag wall of the inflatable head 120 abut against the inner surface of the groove 210 . The pressure and friction on the airbag wall surface of the expansion head 120 and the inner wall surface of the groove 210 increase, so that the door seal 100 tightens the door body 300 and the box body 200, improving the heat preservation effect of the refrigerator. Preferably, in this embodiment, the end of the expansion head 120 has a circular surface structure 121 , and the bottom of the groove 210 is provided with a circular groove that accommodates the circular surface structure 121 . When the expansion head 120 is filled with air, the circular surface structure 121 expands in the circular groove, further tightening the door body 300 and the box body 200, making it more difficult to separate the door body 300 and the box body 200, and further improving the insulation effect of the refrigerator.

The time period acquiring module 600 is configured to acquire the time period when the refrigerator door 300 is opened more than a preset threshold. The time period acquiring module 600 is further configured to obtain the time period according to statistics of the door opening and closing records of the refrigerator or receive a time period set by the user.

In this embodiment, the time period acquisition module 600 can count the number of times the user opens the door. The time segment acquisition module 600 can pre-set the timing cycle first, and divide the timing cycle into a plurality of statistical time segments, and then set a corresponding counter for each statistical time segment, and perform a process in the corresponding counter according to the moment when the door opening and closing event occurs. count. The aforementioned timing period may be one day or one week. For example, in this embodiment, the timing cycle is one day, and 72 statistical time periods can be set in units of 20 minutes per day, which are respectively: 00:00 to 00:20, 00:20 to 00:40, ..., 23 :20 to 23:40, 23:40 to 00:00. A corresponding counter is set for each statistical time period, that is, a total of 72 counters are set. Count in the corresponding counter according to the time when the door opening and closing event occurs. For example, when the opening and closing event occurs at 08:10, then add 1 to the counter corresponding to the time period from 08:00 to 08:20. After counting a certain number of timing cycles, the time period acquisition module 600 records the time period when the refrigerator door 300 is opened more than a preset threshold. For example, if the preset threshold is 5, and the number of counts of the corresponding counter is 7 during the time period from 08:00 to 08:20, then 08:00 to 08:20 is the time period that meets the above requirements. The aforementioned preset threshold may be determined according to the timing period and the size of the statistical time period. In this embodiment, the preset threshold may be 10, that is, the user opens the door 300 approximately every 2 minutes. In some other embodiments, the above time period may be actively set by the user. The door 300 of the refrigerator in this embodiment is provided with an operation panel, through which the user can input the time period information set by himself, so as to save the statistical operation of the refrigerator.

The time acquiring module 700 is configured to acquire the running time of the refrigerator. The time acquisition module 700 may include a clock table, and the time acquisition module 700 determines the current running time of the refrigerator by querying the clock table.

The main control module 800 is configured to judge whether the running time is within the time period, and if the judgment result is yes, control the refrigerator to enter the door seal inflation delay mode; wherein the door seal inflation delay mode is set to, when the refrigerator detects the door closing signal, the air pump 500 The sealing air bag 111 is inflated after a preset time interval, and if the door opening signal is detected within the preset time interval, the air pump 500 is canceled to inflate or deflate the air sealing bag 111 .

During the above time period, according to the habit of the user, the door will be opened and closed frequently. In order to reduce the times of flushing and deflation of the sealing air bag 111, the main control module 800 controls the refrigerator to enter the door seal inflation delay mode. In this mode, when the refrigerator detects the door closing signal, the air pump 500 will not inflate the sealed airbag 111 immediately, but will inflate the sealed airbag 111 after a preset time interval. If the user opens the refrigerator door 300 again within the preset time range of detecting the door closing signal, it is not necessary to inflate the airtight air bag 111 again. Since the sealing airbag 111 has not been inflated all the time, it is not necessary to deflate the sealing airbag 111 after the door opening signal is detected. Such setting, on the one hand, reduces the times of inflating and deflation of the sealed air bag 111 , and on the other hand, reduces the times of starting the air pump 500 , prolonging the service life of the air pump 500 .

In this embodiment, the main control module 800 is further configured to determine whether the refrigerator enters the cooling state, and if so, control the refrigerator to exit the door seal inflation delay mode. The refrigerator in this embodiment further includes: a temperature sensor 900 , a compressor 1000 and an air duct fan 1100 . The temperature sensor 900 is disposed inside the compartment and is configured to detect the temperature inside the compartment of the refrigerator. The compressor 1000 is used for refrigeration of a refrigerator, and includes a compressor fan 1010 . The air duct fan 1100 is arranged at the connection port between the air duct of the refrigerator and the compartment, and is configured to send the cold generated by the compressor 1000 to the interior of the compartment. In this embodiment, the refrigerator is an air-cooled refrigerator, the evaporator of the refrigerator is arranged in the air duct, and the air duct fan 1100 is used to blow the cold air in the air duct into the compartment.

The main control module 800 is also configured to determine whether the temperature reaches the preset compressor start-up temperature, and if so, detect whether the air duct fan 1100 and the compressor fan 1010 of the refrigerator are turned on, and if so, determine that the refrigerator enters the cooling state. In this embodiment, the main control module 800 can judge whether the refrigerator is in a cooling state according to the working states of the compressor 1000 and the air duct fan 1100 . First, the temperature sensor 900 detects the temperature inside the compartment of the refrigerator. When the temperature inside the compartment is too high and has reached the preset start-up temperature of the compressor, the compressor 1000 is ready to be turned on for cooling. However, if the refrigerator is defrosting the evaporator at this time or has just finished defrosting, the temperature of the evaporator is high due to being heated, so it is not suitable to directly perform refrigeration at this time. Usually in this case, the compressor 1000 will be delayed for a period of time before starting, and the air duct fan 1100 will also be delayed for a period of time to start, so as to prevent hot air from being blown into the compartment and affect food freshness. Therefore, only when the temperature inside the compartment reaches the preset start-up temperature of the compressor and it is detected that both the compressor fan 1010 and the air duct fan 1100 are turned on, can it be determined that the refrigerator enters the cooling state.

Although the door seal inflation delay mode is beneficial to reduce the number of times the door seal 100 is inflated and deflated, due to the delayed inflation of the sealed air bag 111, the sealing air bag 111 is not inflated within a preset time after the door body 300 is closed. Affect the sealing performance and heat preservation effect of the refrigerator. Especially when the refrigerator is cooling, the internal temperature of the refrigerator compartment is reduced. In order to ensure that the cooling capacity of the refrigerator does not leak out, it is not suitable to use the door seal inflation delay mode. Therefore, when the main control module 800 determines that the refrigerator has entered the cooling state, it controls the refrigerator to exit the door seal inflation delay mode and returns to the normal state, that is, it inflates immediately after detecting the door closing signal, and deflates immediately after detecting the door opening signal, so as to ensure that the refrigerator Cooling effect.

In this embodiment, the main control module 800 also controls the refrigerator to exit the door seal inflation delay mode when it detects that the operating time exceeds the time period, so as to ensure the refrigerator's heat preservation effect.

According to another aspect of the present invention, a method for controlling a refrigerator is also provided. FIG. 6 is a schematic diagram of a method for controlling a refrigerator according to an embodiment of the present invention; the method includes:

In step S602, the time period during which the number of openings of the refrigerator door 300 exceeds a preset threshold is acquired. In this embodiment, the timing cycle can be preset first, and the timing cycle can be divided into a plurality of statistical time periods, and then a corresponding counter can be set for each statistical time period, and the timing can be performed in the corresponding counter according to the moment when the door opening and closing event occurs. count. Then, a time period satisfying that the number of openings of the door body 300 exceeds a preset threshold is screened out.

Step S604, acquiring the running time of the refrigerator. In this embodiment, the refrigerator can determine the current operating time of the refrigerator by querying the built-in clock table.

Step S606, judging whether the running time is within the time period. For example, if the above time period is 9:00-9:30 and the current time is 9:05, it is determined that the running time is within the time period.

Step S608, if the judgment result of step S606 is "Yes", control the refrigerator to enter the door seal inflation delay mode. If the judgment result is no, the step of obtaining the running time of the refrigerator is continued after a period of time interval.

Fig. 7 is a schematic diagram of a refrigerator door seal 100 according to an embodiment of the present invention inflating and deflated under normal conditions; Schematic diagram of the inflation and deflation operation method.

Under normal circumstances, the operation of the refrigerator to inflate and deflate the door seal 100 includes:

In step S702, a door closing signal is detected.

Step S704 , inflating the sealing airbag 111 of the refrigerator door seal 100 , so that the air inside the sealing airbag 111 is sufficient. Since the heat insulation effect of the air is far stronger than that of the door seal 100 rubber strips, filling the sealed air bag 111 with air can improve the heat preservation effect of the refrigerator.

In step S706, a door opening signal is detected.

Step S708 , deflate the sealing air bag 111 of the refrigerator door seal 100 . After the sealing air bag 111 is deflated, the adsorption force between the door seal 100 and the box body 200 becomes weaker, which is beneficial for the door body 300 to open.

In the door seal inflation delay mode, the operation of the refrigerator to inflate and deflate the door seal 100 includes:

In step S802, a door closing signal is detected.

Step S804, judging whether a door opening signal is detected within a preset time. The aforementioned preset time may be set according to the user's operating frequency of the refrigerator within the time period, for example, it may be 1 minute.

Step S806, if the judgment result of step S804 is yes, cancel the operation of inflating or deflation of the sealed air bag 111 . If the user opens the refrigerator door 300 again within the preset time range of detecting the door closing signal, it is not necessary to inflate the airtight air bag 111 again. Since the sealing airbag 111 has not been inflated all the time, it is not necessary to deflate the sealing airbag 111 after the door opening signal is detected.

In step S808, if the judgment result of step S804 is negative, after an interval of the above-mentioned preset time, the sealing air bag 111 is inflated. If the user has not opened the door body 300 of the refrigerator within the preset time, then an inflation operation is performed to enhance the heat preservation effect of the refrigerator.

In step S810, a door opening signal is detected.

Step S812 , deflate the sealing air bag 111 of the refrigerator door seal 100 .

According to the above description, under normal circumstances, as long as the refrigerator detects the door closing signal, it will immediately inflate the air bag 111 of the refrigerator door seal 100, and when the door opening signal is detected, it will immediately deflate the air bag 111 of the refrigerator door seal 100. There may be no operation delay time. In the door seal inflation delay mode, after the refrigerator detects the door closing signal, the inflation operation of the door seal 100 will be delayed. Such setting, on the one hand, reduces the times of inflating and deflation of the sealed air bag 111 , and on the other hand, reduces the times of starting the air pump 500 , prolonging the service life of the air pump 500 . Especially in the time period when the user frequently uses the refrigerator, the effect is remarkable.

Fig. 9 is a flowchart of a method for controlling a refrigerator according to an embodiment of the present invention, the method executes the following steps in sequence:

Step S902, acquiring a time period during which the number of openings of the refrigerator door 300 exceeds a preset threshold.

Step S904, acquiring the running time of the refrigerator.

Step S906, judging whether the running time is within the time period.

Step S908, if the judgment result of step S906 is "Yes", control the refrigerator to enter the door seal inflation delay mode. If the judgment result is "No", continue to perform the operation of acquiring the running time of the refrigerator after a certain period of time. The period of interval may be set according to the size of the above time period, for example, it may be 1 minute.

Step S910, judging whether the refrigerator enters the cooling state. In this embodiment, it can be judged whether the refrigerator has entered the cooling state according to the working state of the compressor 1000 and the refrigerator air duct fan 1100. Status flags are determined.

Step S912, if the judgment result of step S910 is "Yes", control the refrigerator to exit the door seal inflation delay mode. Although the door seal inflation delay mode is beneficial to reduce the number of times the door seal 100 is inflated and deflated, due to the delayed inflation of the sealed air bag 111, the sealing air bag 111 is not inflated within a preset time after the door body 300 is closed. Affect the sealing performance and heat preservation effect of the refrigerator. Especially when the refrigerator is cooling, the internal temperature of the refrigerator compartment is reduced. In order to ensure that the cooling capacity of the refrigerator does not leak out, it is not suitable to use the door seal inflation delay mode. Therefore, when the main control module 800 determines that the refrigerator has entered the cooling state, it controls the refrigerator to exit the door seal inflation delay mode and returns to the normal state, that is, it inflates immediately after detecting the door closing signal, and deflates immediately after detecting the door opening signal, so as to ensure that the refrigerator Cooling effect. If the judgment result of step S910 is "No", after a period of time, the step of judging whether the refrigerator enters the cooling state is executed again. As long as it is confirmed that the refrigerator enters the cooling state, the refrigerator is controlled to exit the door seal inflation delay mode.

After the refrigerator exits the delay mode, continue to execute the step of obtaining the operating time of the refrigerator at intervals. If the time is still within the above-mentioned time period, continue to execute the subsequent steps; if the time has exceeded the above-mentioned time period, you can stop performing the subsequent steps. . In addition, when the refrigerator is in the door seal inflation delay mode and it is detected that the operation time of the refrigerator has exceeded the above-mentioned time period, it will immediately exit the door seal inflation delay mode.

FIG. 10 is a flow chart of a method for controlling a refrigerator according to another embodiment of the present invention. This method is used to judge whether the refrigerator has entered the cooling state. The method performs the following steps in sequence:

Step S1002, detecting the temperature inside the refrigerator compartment. In this embodiment, the temperature inside the compartment is detected by the temperature sensor 900 built into the refrigerator.

Step S1004, judging whether the above temperature has reached the start-up temperature of the compressor. The starting temperature of the above-mentioned compressor may be the maximum temperature allowed to be reached inside the compartment preset by the refrigerator. If the judgment result of step S1004 is "No" and the compressor 1000 will not start, then it can be directly concluded that the refrigerator is not in the cooling state, and there is no need to perform subsequent steps.

In step S1006, if the determination result of step S1004 is "yes", then it is determined whether the air duct fan 1100 and the compressor fan 1010 of the refrigerator are turned on. When the temperature inside the compartment is too high and has reached the preset start-up temperature of the compressor, the compressor 1000 is ready to be turned on for cooling. However, if the refrigerator is defrosting the evaporator at this time or has just finished defrosting, the temperature of the evaporator is high due to being heated, so it is not suitable to directly refrigerate at this time. Usually in this case, the compressor 1000 will be delayed for a period of time before starting, and the air duct fan 1100 will also be delayed for a period of time to start, so as to prevent hot air from being blown into the compartment and affect food freshness. During this delay time, the refrigerator does not really enter the cooling state.

In step S1008, if the judgment result in step S1006 is "Yes", it is determined that the refrigerator enters the cooling state. Only when the temperature inside the compartment has reached the preset start-up temperature of the compressor and it is detected that both the compressor fan 1010 and the air duct fan 1100 have been turned on, can it be determined that the refrigerator has entered the cooling state.

Step S1010, if the judgment result of step S1006 is "No", it is determined that the refrigerator is not in the cooling state.
