Referring to fig. 2 and 3, fig. 2 is a first flow chart of a control method of a refrigerator according to an embodiment of the present application, and fig. 3 is a flow chart of step S130 shown in fig. 2. The specific flow of the control method of the refrigerator provided by the embodiment of the application may be as follows:
110, obtaining the temperature value of the electromagnetic fresh-keeping chamber.
During the use of the refrigerator, the temperature of the electromagnetic fresh-keeping compartment 30 is constantly changed due to the heat exchange between the inside and the outside. In order to acquire the temperature value in the electromagnetic fresh-keeping compartment 30 in real time, a first temperature sensor 31 is arranged in the electromagnetic fresh-keeping compartment 30, and the first temperature sensor 31 can acquire the temperature value of the electromagnetic fresh-keeping compartment 30.
120, obtaining a temperature value of the electromagnetic module.
The electromagnetic module 20 includes an electromagnetic coil, which itself has a resistance value, and continuously dissipates heat in an energized state, thereby causing a temperature rise of the electromagnetic module 20. Because the electromagnetic module 20 is connected to and directly contacts the electromagnetic fresh-keeping compartment 30, the heat of the electromagnetic module 20 is transferred to the electromagnetic fresh-keeping compartment 30, causing the temperature of the electromagnetic fresh-keeping compartment 30 to rise.
To acquire the temperature value of the electromagnetic module 20 in real time, the electromagnetic module 20 may include a second temperature sensor 21, the second temperature sensor 21 is disposed in the cavity of the electromagnetic module 20, and the temperature value of the electromagnetic module 20 is acquired through the second temperature sensor 21.
130, controlling the first air door to open or close according to the temperature value of the electromagnetic module and the temperature value of the electromagnetic fresh-keeping compartment, wherein the first air door is used for connecting or disconnecting cold air circulation between the electromagnetic module and the freezing chamber of the refrigerator.
It should be noted that, after the first air door 22 is opened, the fan 60 starts to operate, cold air in the freezing chamber 50 enters the first air duct 23, flows to the air inlet of the electromagnetic module 20 through the first air door 22 and enters the cavity of the electromagnetic module 20, the electromagnetic coil contacts with the cold air flow to perform heat exchange, the cold air flow absorbs heat through heat exchange and finally takes away heat, and then flows to the freezing chamber 50 through the air outlet of the electromagnetic module 20, so as to realize cold air circulation between the electromagnetic module 20 and the freezing chamber 50, and cool the electromagnetic module 20.
When the temperature of the electromagnetic module 20 is reduced, the first air door 22 can be controlled to be closed, and the fan 60 stops running at the moment, that is, the cold air is stopped being supplied to the electromagnetic module 20, and the cold air circulation between the electromagnetic module 20 and the freezing chamber 50 is interrupted. The first damper 22 can maintain the low temperature environment of the electromagnetic module 20 in a closed state, and can also reduce the energy consumption of the refrigerator.
In this embodiment, the first air door 22 is controlled to be opened or closed according to the temperature value of the electromagnetic module 20 and the temperature value of the electromagnetic fresh-keeping compartment 30, and for a more clear description, please continue to refer to fig. 2. Wherein, according to the temperature value of electromagnetic module and the temperature value of electromagnetism fresh-keeping room, control first air door to open or close includes following steps:
131, calculating a first temperature difference value between the temperature value of the electromagnetic module and the temperature value of the electromagnetic fresh-keeping chamber.
Since the electromagnetic coil continuously dissipates heat in the energized state, the temperature of the electromagnetic module 20 increases, and thus a temperature difference exists between the electromagnetic module 20 and the electromagnetic fresh-keeping compartment 30. And calculating a first temperature difference value between the temperature value of the electromagnetic module 20 and the temperature value of the electromagnetic fresh-keeping compartment 30 by the acquired temperature value of the electromagnetic coil and the temperature value of the electromagnetic fresh-keeping compartment 30.
132, determining whether the first temperature difference value is greater than a first temperature difference threshold.
And 133, if the first temperature difference value is greater than the first temperature difference threshold value, controlling the first air door to open so as to reduce the temperature of the electromagnetic module.
The first temperature difference threshold may also be understood as a temperature correction value, i.e. a temperature difference that allows a set temperature difference between the electromagnetic module 20 and the electromagnetic fresh compartment 30. Preferably, the temperature of electromagnetic module 20 is the same as or slightly lower than the temperature of electromagnetic fresh compartment 30.
When the first temperature difference value is greater than the first temperature difference threshold, that is, the temperature value of the electromagnetic module 20 exceeds the set requirement, the temperature of the electromagnetic module 20 is too high, which causes the temperature of the electromagnetic fresh-keeping compartment 30 to rise, at this time, the first air door 22 is controlled to open, the fan 60 starts to operate, cold air in the freezing chamber 50 enters the first air duct 23, then flows to the air inlet of the electromagnetic module 20 through the first air door 22 and enters the cavity of the electromagnetic module 20, the electromagnetic coil contacts with the cold air flow to perform heat exchange, the cold air flow absorbs heat through the heat exchange and finally takes away heat, and then flows to the freezing chamber 50 through the air outlet of the electromagnetic module 20, thereby realizing cold air circulation between the electromagnetic module 20 and the freezing chamber 50 to cool the electromagnetic module 20.
It should be noted that, when the first temperature difference value is less than or equal to the first temperature difference threshold, that is, the temperature value of the electromagnetic module 20 meets the set requirement, the electromagnetic module 20 does not cause abnormal temperature rise of the electromagnetic fresh-keeping compartment 30, and at this time, the first air door 22 maintains a closed state, so as to reduce the energy consumption of the refrigerator.
With continued reference to fig. 2, step 133 further includes:
134, obtaining the temperature value of the electromagnetic module after the temperature is reduced.
It will be appreciated that after step 133, the first damper 22 is in an open state, i.e. cold air in the freezing chamber 50 can enter the cavity of the electromagnetic module 20 through the first damper 22 to reduce the temperature of the electromagnetic module 20. If the temperature of the electromagnetic module 20 is too low, the electromagnetic fresh-keeping compartment 30 is also affected, so that the temperature is reduced and even frosted, and the fresh-keeping effect of the food materials is affected. Thus, the second temperature sensor 21 acquires the temperature value of the electromagnetic module 20 after the temperature is lowered after a certain interval.
135, calculating a second temperature difference value between the temperature value of the electromagnetic module after temperature reduction and the temperature value of the electromagnetic fresh-keeping compartment.
Since the first damper 22 is in the open state, the temperature of the electromagnetic module 20 is reduced, for example, the temperature of the electromagnetic module 20 may be lower than the temperature of the electromagnetic fresh-keeping compartment 30, and there is a temperature difference between the temperature value of the electromagnetic module 20 after the temperature reduction and the temperature value of the electromagnetic fresh-keeping compartment 30, that is, the second temperature difference. The second temperature difference value may be the same as or different from the first temperature difference value.
136, determining whether the second temperature difference value is less than or equal to a second temperature difference threshold.
137, if the second temperature difference is less than or equal to the second temperature difference threshold, then the first damper 22 is controlled to close.
The second temperature difference threshold may also be understood as a temperature correction value, i.e. a temperature difference that allows a set temperature difference between the electromagnetic module 20 and the electromagnetic fresh compartment 30. The second temperature difference threshold value may be the same as or different from the first temperature difference threshold value, and may be specifically set according to actual conditions, which is not specifically limited in this application.
When the second temperature difference value is smaller than or equal to the second temperature difference threshold, that is, the temperature of the electromagnetic module 20 meets the set requirement, the first air door 22 is controlled to be closed, the fan 60 stops running, that is, the cold air is stopped being supplied to the electromagnetic module 20, and the cold air circulation between the electromagnetic module 20 and the freezing chamber 50 is interrupted.
It should be noted that, when the second temperature difference value is greater than the second temperature difference threshold, that is, the temperature value of the electromagnetic module 20 after the temperature is reduced exceeds the set requirement, that is, the temperature of the electromagnetic module 20 is still too high to affect the electromagnetic fresh-keeping compartment 30, at this time, the first air door 22 is still kept in an open state, so that cold air in the freezing chamber 50 can flow to the electromagnetic module 20 to reduce the temperature of the electromagnetic module 20, and steps 134 to 136 are repeated until the second temperature difference value is less than or equal to the second temperature difference threshold, step 137 is executed to control the first air door 22 to close, so as to save the power consumption of the refrigerator.
With continued reference to fig. 4, fig. 4 is a second flow chart of a control method of a refrigerator according to an embodiment of the present application. Wherein, after obtaining the temperature value of the electromagnetic module, the method further comprises the following steps:
111, judging whether the temperature value of the electromagnetic fresh-keeping compartment is larger than a first preset temperature threshold value.
112, if the temperature value of the electromagnetic fresh-keeping compartment is greater than the first preset temperature threshold, controlling the second air door to open so as to reduce the temperature of the electromagnetic fresh-keeping compartment.
113, obtaining the temperature value of the electromagnetic fresh-keeping chamber after the temperature is reduced.
114, judging whether the temperature value of the reduced temperature of the electromagnetic fresh-keeping compartment is smaller than or equal to a first preset temperature threshold value.
115, if the temperature value of the reduced temperature of the electromagnetic fresh-keeping compartment is less than or equal to the first preset temperature threshold value, controlling the second air door to be closed.
It should be noted that, the second air door 32 and the first air door 22 are both separately controlled, the first air door 22 is used for connecting or disconnecting the cold air circulation between the electromagnetic module 20 and the freezing chamber 50, and the second air door 32 is used for connecting or disconnecting the cold air circulation between the electromagnetic fresh-keeping compartment 30 and the freezing chamber 50.
When the temperature value of the electromagnetic fresh-keeping compartment 30 is greater than the first preset temperature threshold, the second air door 32 is controlled to be opened, the fan 60 starts to operate, cold air of the freezing compartment 50 enters the second air duct 33, then flows to the air inlet of the electromagnetic fresh-keeping compartment 30 through the second air door 32 and enters the electromagnetic fresh-keeping compartment 30, the cold air flows through the heat exchange to absorb heat and finally take away heat, and then flows to the freezing compartment 50 through the air outlet of the electromagnetic fresh-keeping compartment 30, so that cold air circulation between the electromagnetic fresh-keeping compartment 30 and the freezing compartment 50 is realized, and the temperature of the electromagnetic fresh-keeping compartment 30 is reduced, so that food materials are prevented from deteriorating due to overhigh temperature of the electromagnetic fresh-keeping compartment 30.
It should be noted that, when the temperature value of the electromagnetic fresh-keeping compartment 30 is less than or equal to the first preset temperature threshold, it is indicated that the temperature value of the electromagnetic fresh-keeping compartment 30 meets the set requirement, and at this time, the second air door 32 can be continuously kept in the closed state, so as to save the energy consumption of the refrigerator.
After step 112, the second damper 32 is opened at this time, that is, cold air of the freezing chamber 50 can enter the electromagnetic fresh food compartment 30 through the second damper 32 to lower the temperature of the electromagnetic fresh food compartment 30. If the temperature of the electromagnetic fresh-keeping compartment 30 is too low, food materials may be frosted to affect the fresh-keeping effect. Thus, the first temperature sensor 31 collects the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is lowered at a certain interval.
When the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is reduced is smaller than or equal to the first preset temperature threshold, the temperature value of the electromagnetic fresh-keeping compartment 30 is indicated to meet the set requirement, and at the moment, the second air door 32 is controlled to be closed, and the cold air is stopped being fed into the electromagnetic fresh-keeping compartment 30.
It should be noted that, when the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is reduced is greater than the first preset temperature threshold, that is, the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is reduced is still higher than the set requirement, the second air door 32 maintains the open state at this time, so that cold air in the freezing chamber 50 can flow to the electromagnetic fresh-keeping compartment 30 to reduce the temperature of the electromagnetic fresh-keeping compartment 30, and steps 113 and 114 are repeated until the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is reduced is less than or equal to the first preset temperature threshold, step 115 is performed, and the second air door 32 is controlled to be closed, so as to save the power consumption of the refrigerator.
It can be appreciated that, according to the refrigerator control method provided by the embodiment of the application, by separately controlling the first air door 22 and the second air door 32, not only the normal temperature requirement of the electromagnetic fresh-keeping compartment 30 can be ensured, but also the temperature of the electromagnetic module 20 can be timely regulated and controlled, so that the abnormal temperature rise of the electromagnetic fresh-keeping compartment 30 caused by the overhigh temperature of the electromagnetic module 20 is prevented, the accurate temperature control of the electromagnetic fresh-keeping compartment 30 is facilitated, the temperature uniformity of the electromagnetic fresh-keeping compartment 30 is ensured, and the fresh-keeping effect is improved.

and 210, acquiring the temperature value of the refrigerating compartment.
211, judging whether the temperature value of the refrigerating compartment is larger than a second preset temperature threshold value.
212, if the temperature value of the refrigerating compartment is greater than the second preset temperature threshold value, controlling the third air door to open so as to reduce the temperature of the refrigerating compartment.
213, obtaining the temperature value of the refrigerated compartment after the temperature is reduced.
214, determining whether the temperature value of the refrigerated compartment after the temperature reduction is less than or equal to a second preset temperature threshold.
215, if the temperature value of the refrigerating compartment is less than or equal to the second preset temperature threshold value, controlling the third air door to be closed.

Thus, the third temperature sensor 41 collects the temperature value of the electromagnetic fresh-keeping compartment 30 after the temperature is lowered at a certain interval.
When the temperature value of the cooled compartment 40 is less than or equal to the second preset temperature threshold, the third damper 42 is controlled to be closed, and the cold air is stopped from being supplied to the electromagnetic fresh compartment 30.
It should be noted that, when the temperature value of the cooled compartment 40 is greater than the second preset temperature threshold, that is, the temperature of the cooled compartment 40 is still too high, the second air door 32 is kept open, so that cold air in the freezing compartment 50 can flow to the cooled compartment 40 to lower the temperature of the cooled compartment 40, and steps 213 and 214 are repeated until the temperature value of the cooled compartment 40 is less than or equal to the first preset temperature threshold, step 115 is performed to control the third air door 42 to be closed, so as to save the power consumption of the refrigerator.
