The air duct assembly 300 includes: an air duct back plate 330, a refrigerating air duct cover plate 340, a freezing air duct insulation plate 350 and a freezing air duct cover plate 360.

As shown in fig. 5, the air duct back plate 330 of the air duct assembly 300 is installed in cooperation with the freezing air duct cover plate 360 to define the freezing air duct 310, the freezing fan 400 delivers gas into the freezing chamber 100 through the freezing air duct 310, and a freezing air duct insulation plate 350 is further installed between the air duct back plate 330 and the freezing air duct cover plate 360 to perform a temperature isolation function, so as to prevent low temperature in the freezing chamber 100 from freezing the freezing fan 400 and the refrigerating fan 500.

A refrigerating sensor 323 for detecting a temperature in the refrigerating compartment 200 is provided in the refrigerating compartment 200; a freezing sensor 313 is provided in the freezing chamber 100 to detect the temperature in the freezing chamber 100.
The refrigerator further includes an input device for receiving a user input and a controller for controlling an operation state of the refrigerator.
The input device can be an entity key, a control panel and a voice input device on the refrigerator, and the user can also input an instruction to the refrigerator through a remote controller or a terminal such as a mobile phone, a tablet or a computer.
The controller of the refrigerator, which is electrically connected to the input device, may be configured to control power-on duty ratios of the refrigerating fan 500 and the freezing fan 400 based on the input of the user, the temperature of the refrigerating chamber 200 of the refrigerator, and the temperature of the freezing chamber 100, and thus to control the supply of air to the freezing chamber 100 and the refrigerating chamber 200, and thus to control the temperatures of the freezing chamber 100 and the refrigerating chamber 200.
And the power-on duty ratio of the fan is the duty ratio of the running of the fan.
In this embodiment, the controller may switch the temperature of the freezing chamber 100 from the freezing temperature range to the refrigerating temperature range by controlling the operation of the freezing fan 400, so as to meet the requirement of the refrigerator that the freezing chamber 100 is switched from the freezing mode to the refrigerating mode, increase the volume of the refrigerating functional area of the refrigerator, and meet the use requirement of the user.
The refrigerating temperature range can be 0-8 ℃, and the freezing temperature range can be-24-16 ℃.
The controller may be configured to control the freezing chamber 100 to enter the cold storage mode based on a first input from a user such that the freezing chamber temperature is maintained within a second target range while the refrigerating chamber temperature is maintained within a first target range.
Wherein the first target range is a refrigerating temperature range of the refrigerating compartment 200, the first target range is a refrigerating compartment set temperature ± a refrigerating compartment temperature fluctuation value, the second target range is a refrigerating temperature range of the freezing compartment 100, and the second target range is a freezing compartment set temperature ± a freezing compartment temperature fluctuation value.
It can be understood that the volume of the refrigerating chamber is larger than that of the freezing chamber, the temperature fluctuation value of the refrigerating chamber is set to be larger than that of the freezing chamber, the refrigerating effect of the freezing chamber and the refrigerating chamber can be guaranteed, meanwhile, the frequency of starting the compressor is reduced, and the energy-saving purpose is achieved.
For example, when the refrigerating chamber set temperature and the freezing chamber set temperature are the same, both are 4 degrees celsius, the first target range is 2 to 6 degrees celsius, the second target range is 0 to 8 degrees celsius, and the refrigerating chamber temperature fluctuation value of 2 degrees celsius is greater than the freezing chamber temperature fluctuation value of 1 degree celsius.
For another example, when the refrigerating compartment set temperature and the freezing compartment set temperature are different, when the refrigerating compartment set temperature is 4 degrees celsius and the freezing compartment set temperature is 5 degrees celsius, the first target range is 2 to 6 degrees celsius, the second target range is 4 to 6 degrees celsius, and the refrigerating compartment temperature fluctuation value of 2 degrees celsius is greater than the freezing compartment temperature fluctuation value of 1 degree celsius.
In this step, the controller controls the freezing chamber 100 to switch from the freezing mode to the refrigerating mode, it is necessary to determine the temperature of the freezing chamber 100, and when the freezing chamber temperature is greater than the first target temperature, the freezing chamber temperature is close to the second target range, and the freezing chamber 100 can be directly controlled according to the refrigerating mode.
The controller detects that the temperature of the refrigerating chamber is out of the first target range through the refrigerating sensor 323 and the freezing sensor 313, and when the temperature of the freezing chamber is within the second target range, the refrigerating chamber 200 has a refrigerating requirement, and the freezing chamber 100 has no refrigerating requirement.
The controller controls the compressor to operate, cools air, controls the power-on duty ratio of the refrigerating fan 500 to be a first duty ratio, conveys cold air to the refrigerating chamber 200, cools the refrigerating chamber 200, needs to control the power-on duty ratio of the freezing fan 400 to be a second duty ratio, and conveys cold air to the freezing chamber 100.
The freezing fan 400 is controlled to deliver cold air to the freezing chamber 100, so that the freezing chamber 100 is adjusted from a freezing mode to a refrigerating mode, the refrigerating function space of the refrigerator is increased, and the using requirements of users are met.
In implementation, the first duty ratio is greater than the second duty ratio, the first duty ratio may be a high duty ratio whose value is greater than 60%, and the second duty ratio may be a low duty ratio whose value is less than 40%, and the refrigeration fan 500 operating with the first duty ratio can deliver sufficient cold air to the refrigeration compartment 200, so that the refrigeration compartment 200 is rapidly cooled to a first target range, and the refrigeration fan 400 operating with the second duty ratio can deliver part of the cold air to the freezing compartment 100, thereby ensuring a relatively stable temperature range in the freezing compartment 100.
In the refrigerator, the freezing chamber 100 and the refrigerating chamber 200 share one evaporator 600, that is, the freezing fan 400 and the refrigerating fan 500 are located in the same evaporation chamber as the evaporator 600.
When the refrigerating fan 500 operates at the first duty ratio, the refrigerating fan 400 operates at the second duty ratio, so that the freezing chamber 100 can be converted from a freezing temperature region to a refrigerating temperature region, the phenomena that air duct pressure is unbalanced and air flows between the freezing chamber 100 and the refrigerating chamber 200 due to operation of a single fan can be avoided, and the temperature control of the freezing chamber 100 or the refrigerating chamber 200 is not influenced by the other chamber can be ensured. In the related art, the double-fan refrigerator adjusts the temperature of the freezing chamber 100 or the refrigerating chamber 200 by respectively controlling the on and off of the two fans, and one of the fans is often frozen in the operation process of the double fans, so that the temperature of the freezing chamber 100 or the refrigerating chamber 200 cannot be adjusted.
The inventor of the present invention has found through extensive research that, in the related art, two fans operate alternately, and due to the influence of a flow field between the two fans, a reverse suction phenomenon may occur in the freezing chamber 100 or the refrigerating chamber 200 during operation, which may cause air to circulate between the freezing chamber and the refrigerating chamber, thereby affecting the temperature control of the freezing chamber and the refrigerating chamber.
It can be understood that the controller of the present invention, through the cooperation of different power-on duty ratios of the freezing fan 400 and the refrigerating fan 500, can prevent the reverse suction phenomenon from occurring in one of the freezing chamber 100 or the refrigerating chamber 200 while realizing the rapid cooling of the other chamber, and can also prevent the freezing risk from occurring due to the long-time non-operation of one of the fans.
According to the refrigerator provided by the invention, the controller controls the freezing chamber to be switched to the cold storage mode based on the user input, the capacity of the cold storage area of the refrigerator is increased, the user requirements are met, the rapid cooling of the freezing chamber 100 or the cold storage chamber 200 is realized by controlling different duty ratios of the freezing fan 400 and the cold storage fan 500, the occurrence of the inverse air suction phenomenon and the fan freezing phenomenon is avoided, and the safety of the operation of the refrigerator is improved.
In some embodiments, the controller is further configured to control the power-on duty ratio of the refrigeration fan 500 to a third duty ratio and the freezing fan 400 to operate at a fourth duty ratio in a case where the refrigerating chamber temperature is outside the first target range and the freezing chamber temperature is outside the second target range.
In practice, the third duty ratio is greater than the fourth duty ratio, the third duty ratio may be a high duty ratio having a value of more than 60%, the fourth duty ratio may be a medium duty ratio having a value of 40% -60%, the refrigerating fan 500 operates at the high duty ratio, the freezing fan 400 operates at the medium duty ratio, delivers sufficient cold air to the refrigerating chamber 200 and the freezing chamber 100, and simultaneously cools the refrigerating chamber 200 and the freezing chamber 100.
It can be understood that the volume of the freezing chamber 100 is smaller than that of the refrigerating chamber 200, so that the control of the freezing fan 400 at the medium duty ratio can realize sufficient cool air cooling for the freezing chamber 100, and can also reduce power consumption for energy saving.
In some embodiments, the controller is further configured to control the power-on duty ratio of the refrigerating fan 500 to a first duty ratio, to deliver cool air to the refrigerating compartment 200 to cool the refrigerating compartment 200, and to control the power-on duty ratio of the freezing fan 400 to a second duty ratio, to deliver cool air to the freezing compartment 100 to keep the freezing compartment 100 warm, in case the freezing compartment temperature is within a second target range.
The following describes a refrigerator control method according to an embodiment of the present invention with reference to fig. 1 and fig. 2, where an execution subject of the method may be a controller of a refrigerator, or a cloud, or an edge server.
As shown in fig. 1, an embodiment of the present invention provides a refrigerator control method, including step 110 and step 120.
The control method is applied to a refrigerator that can fulfill the requirement of switching the freezing chamber 100 from the freezing mode to the refrigerating mode.
Step 110, receiving a first input of a user.
In the implementation process, a user can input a first input through the entity keys, the control panel and the voice input device on the refrigerator, and the user can also input the first input through a remote controller or a terminal such as a mobile phone, a tablet or a computer.
In this step, the first input is used to control the freezer compartment 100 of the refrigerator to switch from the freezing mode to the refrigerating mode, increasing the volume of the refrigerating functional area of the refrigerator.
Wherein the user inputting the first input may be represented by at least one of the following modes:
first, the user inputs the first input through the entity key, the control panel and the voice input device on the refrigerator.
In this embodiment, the refrigerator is provided with physical keys, a control panel, and a voice input device.
In order to reduce the misoperation rate of the user, the action area of the first input can be limited in a specific area, for example, the physical key or the control panel is mounted on a refrigerator door, so that the user can conveniently click the physical key or touch the control panel to realize the first input.
Secondly, the user inputs the first input through the remote controller.
In this embodiment, the refrigerator may be controlled by a remote controller, which is a separate input device outside the refrigerator body, and the user may implement the first input by pressing or clicking a button on the remote controller.
And thirdly, the user inputs a first input through a mobile phone, a tablet or a computer and other terminals.
In this embodiment, the terminal may be connected to a refrigerator to which the first input is input by a wired or wireless manner.
Of course, in other embodiments, the first input may also be expressed in other forms, which may be determined according to actual needs, and this is not limited in this application.
And step 120, in response to the first input, in the case that the freezing chamber temperature is greater than the first target temperature, the refrigerating chamber temperature of the refrigerator is outside the first target range, and the freezing chamber temperature is within the second target range, controlling the refrigerator compressor to operate, controlling the refrigerating fan 500 to operate at a first duty ratio, and controlling the freezing fan 400 to operate at a second duty ratio.
After receiving the first input, the freezing chamber 100 is controlled to switch from the freezing mode to the refrigerating mode, that is, the refrigerating fan 500 and the freezing fan 400 are controlled to operate such that the refrigerating chamber temperature is maintained within the first target range and the freezing chamber temperature is maintained within the second target range, in response to the first input.
Wherein the first target range is a refrigerating temperature range of the refrigerating compartment 200, which may be 2 to 6 degrees celsius, and the second target range is a refrigerating temperature range of the freezing compartment 100, which may be 0 to 8 degrees celsius.
When the temperature of the refrigerating chamber is kept within the first target range, the refrigerating fan 500 does not need to be controlled to convey a large amount of gas to the refrigerating chamber 200 to cool the refrigerating chamber 200, that is, when the temperature of the refrigerating chamber is kept within the first target range, the refrigerating chamber 200 is in a stop point state, and no refrigerating requirement exists.
When the temperature of the refrigerating chamber is kept outside the first target range, the refrigerating fan 500 needs to be controlled to deliver a large amount of air to the refrigerating chamber 200 to cool or heat the refrigerating chamber 200, that is, when the temperature of the refrigerating chamber is outside the first target range, the refrigerating chamber 200 is in a starting point state, and there is a refrigerating requirement.
It is understood that the freezing chamber 100 is in the cold storage mode, and the freezing chamber 100 is in the stop point state with no refrigeration requirement while the freezing chamber temperature is maintained within the second target range; when the freezer compartment temperature is maintained outside the second target range, the freezer compartment 100 is in the on-point state and there is a refrigeration demand.
In this step, the freezing chamber 100 is controlled to switch from the freezing mode to the refrigerating mode, it is necessary to determine the temperature of the freezing chamber 100, and when the freezing chamber temperature is greater than the first target temperature, the freezing chamber temperature is close to the second target range, and the freezing chamber 100 can be directly controlled according to the refrigerating mode.
The first target temperature may be 0 ℃, the temperature of the freezing chamber is greater than the first target temperature, the freezing chamber 100 does not have a multi-junction ice phenomenon, and the freezing chamber 100 may be directly controlled to enter a cold storage mode.
When the refrigerating chamber temperature is outside the first target range and the freezing chamber temperature is within the second target range, the refrigerating chamber 200 has a cooling demand and the freezing chamber 100 has no cooling demand.
When the temperature of the refrigerating chamber is out of the first target range and the temperature of the freezing chamber is in the second target range, the cold air needs to be delivered into the refrigerating chamber 200, the compressor is controlled to operate to cool the air, the refrigerating fan 500 is controlled to operate at the first duty ratio to deliver the cold air into the refrigerating chamber 200, the refrigerating chamber 200 is cooled, and the freezing fan 400 is controlled to operate at the second duty ratio to deliver the cold air to the freezing chamber 100.
The duty ratio refers to the ratio of the power-on time of the fan to the whole working period in one working period, and the amount of the conveying gas can be controlled by controlling the value of the duty ratio.
In implementation, the first duty ratio is greater than the second duty ratio, the first duty ratio may be a high duty ratio whose value is greater than 60%, and the second duty ratio may be a low duty ratio whose value is less than 40%, so that the refrigerating fan 500 operating at the first duty ratio can deliver sufficient cold air to the refrigerating chamber 200, so that the refrigerating chamber 200 is rapidly cooled to a first target range, and the freezing fan 400 operating at the second duty ratio can deliver part of the cold air to the freezing chamber 100, thereby ensuring a relatively stable temperature range in the freezing chamber 100.
In the related art, the double-fan refrigerator adjusts the temperature of the freezing chamber 100 or the refrigerating chamber 200 by respectively controlling the on and off of the two fans, and does not consider the influence of a flow field between the two fans, so that the phenomenon of reverse suction of the freezing chamber 100 or the refrigerating chamber 200 can occur in the operation process, air circulates between the freezing chamber and the refrigerating chamber, the temperature control of the freezing chamber and the refrigerating chamber is influenced, and a certain fan can be frozen without running for a long time.
It can be understood that, by the cooperation of different duty ratios of the freezing fan 400 and the refrigerating fan 500, when one of the freezing chamber 100 and the refrigerating chamber 200 is rapidly cooled, the reverse suction phenomenon of the other chamber can be avoided, and the freezing risk caused by the long-time non-operation of one of the fans can also be avoided.
According to the refrigerator control method provided by the invention, the freezing chamber is controlled to be switched to the cold storage mode based on the user input, the capacity of the cold storage area of the refrigerator is increased, the user requirement is met, the temperature of the cold storage chamber and the temperature of the freezing chamber are taken as the adjustment basis, and the different duty ratios of the freezing fan 400 and the cold storage fan 500 are controlled, so that the phenomenon of reverse suction and the phenomenon of fan freezing are avoided while the freezing chamber 100 or the cold storage chamber 200 is rapidly cooled, and the safety of the refrigerator operation is improved.

It can be understood that the volume of the freezing chamber 100 is smaller than that of the refrigerating chamber 200, so that the control of the freezing fan 400 at a medium duty ratio can provide sufficient cold air for cooling the freezing chamber 100, reduce power consumption, and achieve the purpose of energy saving.
In some embodiments, after the refrigerating fan 500 and the freezing fan 400 are respectively controlled to operate for a period of time at the third duty ratio and the fourth duty ratio, the refrigerating chamber temperature and the freezing chamber 100 are judged again, and the power-on duty ratios of the refrigerating fan 500 and the freezing fan 400 are adjusted.
In the case that the freezer compartment temperature is within the second target range, that is, there is no refrigeration demand for the freezer compartment 100, and there is a refrigeration demand for the refrigerator compartment 200, the control returns to step 120, where the refrigerator fan 500 is controlled to operate at the first duty ratio to deliver cold air to the refrigerator compartment 200, so as to cool the refrigerator compartment 200, and the freezer fan 400 is controlled to operate at the second duty ratio to deliver cold air to the freezer compartment 100, so as to keep the freezer compartment 100 warm.
In some embodiments, the determination of the refrigerating compartment temperature and the freezing compartment 100 is made again after controlling the refrigerating fan 500 to operate at the first duty ratio to deliver the cold air to the refrigerating compartment 200 and controlling the freezing fan 400 to operate at the second duty ratio to deliver the cold air to the freezing compartment 100 at step 120.
In the case that the freezing chamber temperature is within the second target range and the refrigerating chamber temperature is within the first target range, that is, when neither the freezing chamber 100 nor the refrigerating chamber 200 has a refrigeration demand, the compressor is controlled to stop, and the refrigerating fan 500 and the freezing fan 400 are controlled to stop, so that cold air is not delivered to the freezing chamber 100 and the refrigerating chamber 200, and the freezing chamber temperature is maintained within the second target range and the refrigerating chamber temperature is maintained within the first target range.

After receiving the second input, the freezing chamber 100 is controlled to switch from the cold storage mode to the freezing mode, that is, the operation states of the cold storage fan 500 and the freezing fan 400 are controlled, so that the temperature of the cold storage chamber is kept within the first target range, and the temperature of the freezing chamber is kept within the third target range.
Wherein the first target range is a refrigerating temperature range of the refrigerating compartment 200, which may be 2 to 6 degrees celsius, and the third target range is a freezing temperature range of the freezing compartment 100, which may be-24 to-16 degrees celsius.
