As shown in fig. 3 and 5, a freezing air outlet 311 is distributed above the freezing chamber 100, a freezing air return 312 is distributed below the freezing chamber 100, and the air flowing in the freezing air duct 310 is dispersed in the freezing chamber 100 through the freezing air outlet 311 and returns to the evaporator 600 through the freezing air return 312 below, so that recycling is realized.

A refrigerating sensor 323 is provided in the refrigerating chamber 200 to detect the temperature in the refrigerating chamber 200; a freezing sensor 313 is provided in the freezing chamber 100 for detecting the temperature in the freezing chamber 100.

The refrigerator further includes an input device for receiving user input and a controller for controlling an operation state of the refrigerator.

The input device can be physical keys, a control panel and a voice input device on the refrigerator, and the user can input instructions to the refrigerator through a remote controller or a terminal such as a mobile phone, a tablet or a computer.

A controller of the refrigerator is electrically connected to the input device, and the controller may be configured to control the power-on duty ratio of the refrigerating blower 500 and the freezing blower 400 based on the input of a user, the temperature of the refrigerator's refrigerating compartment 200, and the temperature of the freezing compartment 100, and thus control the air supply to the freezing compartment 100 and the refrigerating compartment 200, and thus control the temperatures of the freezing compartment 100 and the refrigerating compartment 200.

The power-on duty ratio of the fan is the duty ratio of the fan operation.

In this embodiment, the controller can control the operation of the refrigerating fan 400 to switch the temperature of the freezing chamber 100 from the freezing temperature range to the refrigerating temperature range, thereby realizing the need of changing the freezing chamber 100 from the freezing mode to the refrigerating mode, increasing the volume of the refrigerating functional area of the refrigerator, and meeting the use requirement of the user.

Wherein, the refrigerating temperature range can be between 0 ℃ and 8 ℃, and the freezing temperature range can be between-24 ℃ and-16 ℃.

The controller may be configured to control the freezing chamber 100 to enter the refrigerating mode based on a first input of a user such that the freezing chamber temperature is maintained within a second target range while the refrigerating chamber temperature is maintained within the first target range.

The first target range is a refrigerating temperature range of the refrigerating chamber 200, the first target range is a refrigerating chamber set temperature±refrigerating chamber temperature fluctuation value, the second target range is a refrigerating temperature range of the freezing chamber 100, and the second target range is a freezing chamber set temperature±freezing chamber temperature fluctuation value.

It can be understood that the volume of the refrigerating chamber is larger than that of the freezing chamber, and the temperature fluctuation value of the refrigerating chamber is larger than that of the freezing chamber, so that the frequency of starting the compressor can be reduced while the refrigerating effect of the freezing chamber and the refrigerating chamber is ensured, and the aim of saving energy is fulfilled.

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 2 degrees celsius is greater than the freezing chamber temperature fluctuation value 1 degree celsius.

For another example, when the refrigerating chamber set temperature and the freezing chamber set temperature are different, when the refrigerating chamber set temperature is 4 degrees celsius and the freezing chamber 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 chamber temperature fluctuation value 2 degrees celsius is greater than the freezing chamber temperature fluctuation value 1 degree celsius.

In this step, the controller controls the freezing chamber 100 to switch from the freezing mode to the refrigerating mode, and it is necessary to determine the temperature of the freezing chamber 100, and when the temperature of the freezing chamber is greater than the first target temperature, the temperature of the freezing chamber approaches the second target range, and the freezing chamber 100 can be directly controlled according to the refrigerating mode.

When the controller detects that the refrigerating chamber temperature is outside the first target range and the freezing chamber temperature is within the second target range through the refrigerating sensor 323 and the freezing sensor 313, the refrigerating chamber 200 has a refrigerating demand, and the freezing chamber 100 has no refrigerating demand.

The controller controls the compressor to operate, cools the air, controls the power-on duty ratio of the refrigerating fan 500 to be a first duty ratio, delivers cool air to the refrigerating chamber 200, cools the refrigerating chamber 200, and needs to control the power-on duty ratio of the freezing fan 400 to be a second duty ratio, and delivers cool air to the freezing chamber 100.

The refrigerating fan 400 is controlled to deliver cool air to the freezing chamber 100, so that the freezing chamber 100 is adjusted from a freezing mode to a refrigerating mode, the space of the refrigerating function of the refrigerator is increased, and the use requirement of a user is met.

In implementation, the first duty ratio is greater than the second duty ratio, the first duty ratio may be a high duty ratio with a value of more than 60%, the second duty ratio may be a low duty ratio with a value of less than 40%, the refrigeration fan 500 operating with the first duty ratio may deliver sufficient cool 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 may deliver part of cool air to the freezing compartment 100, so as to ensure a relatively stable temperature range in the freezing compartment 100.

In the refrigerator, the freezing compartment 100 and the refrigerating compartment 200 share one evaporator 600, that is, the freezing blower 400 and the refrigerating blower 500 are located in the same evaporation chamber as the evaporator 600.

The refrigerating fan 500 is operated at the first duty ratio, and the freezing fan 400 is operated at the second duty ratio, so that the freezing chamber 100 can be changed from the freezing temperature zone to the refrigerating temperature zone, the phenomenon that air channel air pressure is unbalanced due to the operation of a single fan can be avoided, air flows between the freezing chamber 100 and the refrigerating chamber 200, and the temperature control of the freezing chamber 100 or the refrigerating chamber 200 is not influenced by the other chamber. In the related art, the temperature of the freezing chamber 100 or the refrigerating chamber 200 is adjusted by controlling the on/off of two fans respectively in the double-fan refrigerator, and the temperature of the freezing chamber 100 or the refrigerating chamber 200 cannot be adjusted because one fan is always frozen in the double-fan refrigerator in the operation process.

The inventor has found through a great deal of researches that in the related art, two fans alternately operate, and due to the influence of a flow field between the two fans, a phenomenon that the freezing chamber 100 or the refrigerating chamber 200 may have air suction upside down during the operation process may occur, so that air circulates between the freezing chamber and the refrigerating chamber, and the temperature control of the freezing chamber and the refrigerating chamber is affected.

It can be appreciated that, by matching different power-on duty ratios of the freezing blower 400 and the refrigerating blower 500, the controller of the present invention can realize rapid cooling of one compartment of the freezing chamber 100 or the refrigerating chamber 200, and simultaneously avoid the phenomenon of reverse draft of the other compartment, and can also avoid freezing risk of one of the blowers due to long-time non-operation.

According to the refrigerator provided by the invention, the controller controls the freezing chamber to be switched to the refrigerating mode based on user input, so that the capacity of a refrigerating area of the refrigerator is increased, the requirements of users are met, the rapid cooling of the freezing chamber 100 or the refrigerating chamber 200 is realized by controlling different duty ratios of the freezing fan 400 and the refrigerating fan 500, the phenomenon of air back draft and the phenomenon of freezing of the fan are avoided, and the running safety of the refrigerator is improved.

In some embodiments, the controller is further configured to control the power-on duty cycle of the refrigeration blower 500 to be a third duty cycle and control the refrigeration blower 400 to operate at a fourth duty cycle when the refrigeration chamber temperature is outside the first target range and the freezer chamber temperature is outside the second target range.

In practice, the third duty ratio is greater than the fourth duty ratio, which may be a high duty ratio having a magnitude of 60% or more, and the fourth duty ratio may be a medium duty ratio having a magnitude in the range of 40% -60%, the refrigerating blower 500 is operated at the high duty ratio, and the freezing blower 400 is operated at the medium duty ratio, and sufficient cool air is supplied to the refrigerating chamber 200 and the freezing chamber 100 while cooling the refrigerating chamber 200 and the freezing chamber 100.

It can be appreciated that the volume of the freezing chamber 100 is small relative to the refrigerating chamber 200, so that the control of the freezing blower 400 at the medium duty ratio can achieve the purpose of providing sufficient cool air cooling for the freezing chamber 100, and also reducing power consumption for energy saving.

In some embodiments, the controller is further configured to control the power-on duty ratio of the refrigeration fan 500 to be a first duty ratio, to deliver cool air to the refrigeration compartment 200, to cool the refrigeration compartment 200, and to control the power-on duty ratio of the freezing fan 400 to be a second duty ratio, to deliver cool air to the freezing compartment 100, and to keep the freezing compartment 100 warm, when the temperature of the freezing compartment is within the 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, a cloud, or an edge server of a refrigerator.

As shown in fig. 1, an embodiment of the present invention provides a refrigerator control method, including steps 110 and 120.

The control method is applied to a refrigerator that can fulfill the need of switching the freezing chamber 100 from the freezing mode to the refrigerating mode.

Step 110, a first input of a user is received.

In implementation, the user may input the first input through physical keys, a control panel and a voice input device on the refrigerator, and the user may 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, a first input is used to control the switching of the freezer 100 of the refrigerator from the freezing mode to the refrigerating mode, increasing the volume of the refrigerator's refrigerating functional area.

Wherein the user input first input may be represented as at least one of:

first, a user inputs a first input through a physical key, a control panel and a voice input device on the refrigerator.

In this embodiment, a 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, an entity key or a control panel is arranged on the refrigerator door, so that the user can conveniently click the entity key or touch the control panel, and the first input is realized.

And 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.

Third, the user inputs the first input through the mobile phone, the tablet or the computer and other terminals.

In this embodiment, the terminal may be connected to the refrigerator, and the first input is inputted to the refrigerator through a wired or wireless manner.

Of course, in other embodiments, the first input may also take other forms, which may be specifically determined according to actual needs, and the embodiment of the present application is not limited thereto.

Step 120, in response to the first input, controlling the refrigerator compressor to operate and controlling the refrigeration fan 500 to operate at a first duty cycle and controlling the refrigeration fan 400 to operate at a second duty cycle when 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.

After receiving the first input, the freezing chamber 100 is controlled to switch from the freezing mode to the refrigerating mode, i.e., the operating states of the refrigerating blower 500 and the freezing blower 400 are controlled such that the temperature of the refrigerating chamber is maintained within the first target range and the temperature of the freezing chamber is maintained within the second target range, in response to the first input.

The first target range is a refrigerating temperature range of the refrigerating chamber 200, which may be 2 to 6 degrees celsius, and the second target range is a refrigerating temperature range of the freezing chamber 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 deliver a large amount of air 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 refrigeration 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 warm 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 need for refrigeration.

It will be appreciated that when the freezing chamber 100 is in the refrigeration mode and the freezing chamber temperature is maintained within the second target range, the freezing chamber 100 is in the stop point state, and no refrigeration is required; when the temperature of the freezing chamber is maintained outside the second target range, the freezing chamber 100 is in a start-up point state, and there is a need for cooling.

In this step, the freezing chamber 100 is controlled to switch from the freezing mode to the refrigerating mode, and 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 approaches the second target range, and the freezing chamber 100 can be controlled directly in the refrigerating mode.

The first target temperature may be 0 degrees celsius, the freezing chamber temperature is greater than the first target temperature, the freezing chamber 100 does not have excessive multi-junction ice phenomenon, and the freezing chamber 100 can be directly controlled to enter the refrigeration mode.

When the temperature of the refrigerating chamber is outside the first target range and 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.

When the temperature of the refrigerating compartment is outside the first target range and the temperature of the freezing compartment is within the second target range, it is necessary to supply cool air into the refrigerating compartment 200, control the compressor to operate, cool air, and control the refrigerating fan 500 to operate at the first duty ratio to supply cool air into the refrigerating compartment 200, so as to cool the refrigerating compartment 200, and control the refrigerating fan 400 to operate at the second duty ratio to supply cool air into the freezing compartment 100.

The duty ratio is the ratio of the time of powering on the fan to the whole working period in one working period, and the quantity of the conveying gas can be controlled by controlling the value of the duty ratio.

In the related art, the temperature of the freezing chamber 100 or the refrigerating chamber 200 is adjusted by controlling the on/off of the two fans respectively, and the influence of the flow field between the two fans is not considered, so that the phenomenon of air back draft of the freezing chamber 100 or the refrigerating chamber 200 may occur in the operation process, the air flows between the freezing chamber and the refrigerating chamber, the temperature control of the freezing chamber and the refrigerating chamber is affected, and the freezing of a certain fan may occur without running for a long time.

It can be appreciated that by matching different duty ratios of the freezing blower 400 and the refrigerating blower 500, the invention can prevent the reverse draft phenomenon of one compartment while realizing the rapid cooling of the other compartment of the freezing chamber 100 or the refrigerating chamber 200, and can also avoid the freezing risk of one of the blowers not running for a long time.

According to the refrigerator control method provided by the invention, based on user input, the freezing chamber is controlled to be switched to the refrigerating mode, the capacity of a refrigerating area of the refrigerator is increased, the user requirement is met, the temperature of the refrigerating chamber and the temperature of the freezing chamber are taken as adjustment bases, the different duty ratios of the refrigerating fan 400 and the refrigerating fan 500 are controlled, the rapid cooling of the freezing chamber 100 or the refrigerating chamber 200 is realized, the occurrence of the reverse draft phenomenon and the freezing phenomenon of the fan is avoided, and the running safety of the refrigerator is improved.

In some embodiments, after step 110, further comprising: in response to the first input, in the case where the refrigerating compartment temperature is outside the first target range and the freezing compartment temperature is outside the second target range, the refrigerating blower 500 is controlled to operate at the third duty ratio and the freezing blower 400 is controlled to operate at the fourth duty ratio.

In this step, after receiving the first input, it is determined that the freezing chamber temperature is greater than the first target temperature in response to the first input, and the freezing chamber 100 is directly controlled in the cooling mode.

When the temperature of the refrigerating compartment is outside the first target range and the temperature of the freezing compartment is outside the second target range, both the refrigerating compartment 200 and the freezing compartment 100 have a refrigerating demand, and the compressor operation needs to be controlled, and the air is cooled, and the refrigerating fan 500 and the freezing fan 400 are controlled to input cool air into the refrigerating compartment 200 and the freezing compartment 100, respectively.

In practice, the third duty ratio is greater than the fourth duty ratio, which may be a high duty ratio having a magnitude of 60% or more, and the fourth duty ratio may be a medium duty ratio having a magnitude in the range of 40% -60%, the refrigerating blower 500 is operated at the third duty ratio, the freezing blower 400 is operated at the fourth duty ratio, and sufficient cool air is supplied to the refrigerating compartment 200 and the freezing compartment 100 while cooling the refrigerating compartment 200 and the freezing compartment 100.

In some embodiments, after the refrigerating blower 500 and the freezing blower 400 are controlled to operate for a period of time at the third duty ratio and the fourth duty ratio, respectively, the refrigerating chamber temperature and the freezing chamber 100 are judged again, and the power-on duty ratios of the refrigerating blower 500 and the freezing blower 400 are adjusted.

In the case that the temperature of the freezing chamber is within the second target range, that is, the freezing chamber 100 has no refrigeration requirement, and the refrigerating chamber 200 has a refrigeration requirement, returning to step 120, the control controls the refrigerating fan 500 to operate at the first duty ratio to deliver cold air to the refrigerating chamber 200, so as to cool the refrigerating chamber 200, and controls the refrigerating fan 400 to operate at the second duty ratio to deliver cold air to the freezing chamber 100, so as to preserve heat of the freezing chamber 100.

In some embodiments, after controlling the refrigerating blower 500 to deliver cool air to the refrigerating compartment 200 at the first duty ratio and controlling the freezing blower 400 to deliver cool air to the freezing compartment 100 at the second duty ratio at step 120, a judgment is made again on the refrigerating compartment temperature and the freezing compartment 100.

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 there is no refrigerating demand for both the freezing chamber 100 and the refrigerating chamber 200, the compressor is controlled to be stopped, and the refrigerating fan 500 and the refrigerating fan 400 are controlled to be stopped, cold air is not supplied to the freezing chamber 100 and the refrigerating chamber 200 any more, the freezing chamber temperature is maintained within the second target range, and the refrigerating chamber temperature is maintained within the first target range.

In some embodiments, after receiving the first input, the freezing chamber temperature is collected by the freezing sensor 313 to be not greater than the first target temperature, and at this time, there is a freezing phenomenon in the freezing chamber 100.

Wherein, the defrosting heater is installed in the freezing chamber 100, and the defrosting heater starts defrosting when operating, thereby increasing the temperature of the freezing chamber and reducing the icing phenomenon in the freezing chamber 100.

In this embodiment, the defrosting heater is controlled to operate to defrost, the temperature of the freezing chamber is increased, and when the defrosting exit temperature is reached, the defrosting exit temperature can be the upper limit of the temperature of the freezing chamber 100 in normal operation in the refrigeration mode, and the defrosting heater is controlled to be turned off, so that the freezing chamber 100 is controlled to be rapidly switched to the refrigeration mode.

Wherein the defrost exit temperature may be 8 degrees celsius.

In some embodiments, the freezer 100 operates in a cooling mode, receiving a second input from a user, controlling the freezer 100 to switch back to the cooling mode.

In implementation, the user may input the second input through physical keys, a control panel and a voice input device on the refrigerator, and the user may also input the second input through a remote control, or a terminal such as a mobile phone, a tablet or a computer.

Of course, in other embodiments, the second input may take other forms as well as the first input, which may be specifically determined according to actual needs, and the embodiment of the present application is not limited thereto.

In this embodiment, the second input is for controlling the freezing chamber 100 of the refrigerator to switch from the refrigerating mode back to the freezing mode, restoring the freezing function of the freezing chamber 100 of the refrigerator, and satisfying the user's demand.

After receiving the second input, the freezing chamber 100 is controlled to switch from the refrigerating mode back to the freezing mode, that is, the operation states of the refrigerating blower 500 and the freezing blower 400 are controlled such that the temperature of the refrigerating chamber is maintained within the first target range and the temperature of the freezing chamber is maintained 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.

It is understood that the highest temperature value of the third target range of the freezing temperature range of the freezing compartment 100 is less than the lowest temperature value of the second target range of the refrigerating temperature range of the freezing compartment 100.

The compressor is controlled to operate, the refrigerating fan 400 is controlled to operate at a sixth duty ratio to deliver sufficient cold air to the freezing chamber 100 to cool the freezing chamber 100, and the refrigerating fan 500 is controlled to operate at a fifth duty ratio to deliver the cold air to the refrigerating chamber 200, so that the heat preservation effect of the refrigerating chamber 200 is achieved, and the reverse suction of wind is prevented.

In implementation, the sixth duty cycle is greater than the fifth duty cycle, the sixth duty cycle may be a high duty cycle having a magnitude of 60% or more, and the fifth duty cycle may be a low duty cycle having a magnitude of 40% or less.

After the freezing blower 400 is controlled to operate at the sixth duty ratio for a period of time, in the case that the freezing chamber temperature is within the third temperature range, that is, the freezing chamber 100 has no cooling requirement, the compressor is controlled to be stopped so that the freezing chamber temperature is maintained within the third temperature range.

In some embodiments, when the freezer 100 is operating in the refrigeration mode, the compressor is turned on and off by the refrigeration sensor 323, and when the temperature of the refrigerator 200 is within the first target range, the refrigerator sensor 323 does not control the compressor to be turned on when the refrigerator 200 has no refrigeration demand.

The second target temperature is a high Wen Jingjie value in the refrigerating mode of the freezing chamber 100, and the temperature upper limit value of the second target range is less than the second target temperature, wherein the second target range may be 0 to 8 degrees celsius and the second target temperature may be 10 degrees celsius.

In case that the temperature of the freezing compartment is higher than the second target temperature, the compressor is forcibly controlled to operate, the freezing blower 400 is controlled to operate at the eighth duty ratio to deliver sufficient cool air to the freezing compartment 100, and the refrigerating blower 500 is controlled to operate at the seventh duty ratio to deliver cool air to the refrigerating compartment 200 to prevent wind suck-back for rapid cooling of the freezing compartment 100.

In implementation, the eighth duty cycle is greater than the seventh duty cycle, the eighth duty cycle may be a high duty cycle having a magnitude of 60% or more, and the seventh duty cycle may be a low duty cycle having a magnitude of 40% or less.

In this embodiment, when only the freezing chamber 100 has a refrigeration request and the temperature of the freezing chamber is higher than the second target temperature, the forced control compressor is started, the refrigerating fan 400 is operated with a high duty ratio, the refrigerating fan 500 is operated with a low duty ratio, the freezing chamber 100 is cooled, and after the temperature of the freezing chamber is reduced to the shutdown point, the normal refrigerating mode is restored, so that the problem that the compressor cannot refrigerate when the freezing chamber 100 is overloaded in the refrigerating mode is solved.

In some embodiments, when the freezing chamber 100 is operated in the cooling mode, the compressor is controlled to be stopped and the freezing blower 400 is operated at the ninth duty ratio when the freezing chamber temperature is lower than the third target temperature.

The third target temperature is a low temperature warning value of the freezing chamber 100 in the refrigerating mode, and the temperature lower limit value of the second target range is greater than the third target temperature, wherein the second target range may be 0 to 8 degrees celsius, and the third target temperature may be 0 degrees celsius.

In case that the temperature of the freezing compartment is lower than the third target temperature, the compressor is forcibly controlled to be stopped, the evaporator 600 does not cool the air any more, the freezing blower 400 is controlled to operate at the ninth duty ratio to deliver sufficient air to the freezing compartment 100, the temperatures of the freezing compartment 100 and the refrigerating compartment 200 are balanced, the temperature of the freezing compartment 100 is raised, and when the temperature of the freezing compartment is restored to be within the second target range, the control of the freezing compartment 100 in the refrigerating mode is restored.

In the implementation, the ninth duty ratio can be a high duty ratio with the numerical value more than 60%, and after the compressor is stopped, the operation of only one fan can be controlled, so that the phenomenon of wind back suction can not occur.

In this embodiment, when the temperature of the freezing chamber 100 is too low during the operation in the cooling mode, the forced control compressor is stopped, the freezing blower 400 is operated at a high duty ratio, the temperature is balanced, and the problem of zero crossing of the freezing chamber temperature is solved.

In some embodiments, the freezer 100 is in a freezing mode, wherein the third target range is a freezing temperature range of the freezer 100 and the first target range is a refrigeration temperature range of the refrigerator 200.

In the case that the temperature of the refrigerating compartment is outside the first target range and the temperature of the freezing compartment is outside the third target range, both the refrigerating compartment 200 and the freezing compartment 100 have a refrigerating demand, and the compressor operation needs to be controlled, and the cooling air is cooled, and the refrigerating fan 500 and the freezing fan 400 are controlled to input cool air into the refrigerating compartment 200 and the freezing compartment 100, respectively.

In practice, the refrigerating fan 500 is controlled to operate at a high duty ratio of 60% or more in magnitude, and the freezing fan 400 is controlled to operate at a low duty ratio of 40% or less in magnitude, preferably to cool the refrigerating compartment 200.

It can be appreciated that the volume of the refrigerating compartment 200 is relatively large with respect to the freezing compartment 100, thereby controlling the refrigerating fan 500 at a high duty ratio, realizing rapid cooling of the refrigerating compartment 200, controlling the operation of the freezing fan 400 at a low duty ratio, and effectively preventing the reverse draft phenomenon while realizing a certain cooling effect.

In some embodiments, in the case that the refrigerating compartment temperature is within the first target range and the freezing compartment temperature is outside the third target range, the refrigerating compartment 200 has no cooling requirement, the freezing compartment 100 has a cooling requirement, and the refrigerating fan 500 and the freezing fan 400 are controlled to input cool air to the refrigerating compartment 200 and the freezing compartment 100, respectively.

In implementation, the refrigerating fan 400 is controlled to operate at a high duty ratio with a value of more than 60%, and the refrigerating fan 500 is controlled to operate at a low duty ratio with a value of less than 40%, so that the rapid cooling of the freezing chamber 100 is realized, and the reverse draft phenomenon is effectively prevented.

In some embodiments, when the freezer 100 is operating in the freeze mode, the compressor is turned on and off by the freeze sensor 313, and when the temperature of the freezer 100 is within the third target range, the freeze sensor 313 does not control the compressor to be turned on when the freezer 100 has no refrigeration demand.

When the temperature of the refrigerating chamber is higher than the high-temperature warning value of the refrigerating chamber 200, the compressor is controlled to run forcefully, the refrigerating fan 500 is controlled to run at a high duty ratio, the refrigerating chamber 200 is cooled down rapidly, and the refrigerating fan 400 is controlled to run at a low duty ratio, so that the wind is prevented from being sucked backwards.

In practice, the high temperature alert value for the refrigerator compartment 200 may be 10 degrees celsius.

In this embodiment, when only the refrigerating chamber 200 has a refrigerating request and the temperature of the refrigerating chamber is higher than the high temperature warning value of the refrigerating chamber 200, the forced control compressor is started, the refrigerating fan 500 is operated with a high duty ratio, the refrigerating fan 400 is operated with a low duty ratio, the refrigerating chamber 200 is cooled, and after the temperature of the refrigerating chamber is reduced to the stop point, the normal refrigerating mode is restored, so that the problem that the compressor cannot refrigerate when the refrigerating chamber 200 is overloaded is solved.

In some embodiments, in the case where the temperature of the refrigerating compartment is lower than the refrigerating low temperature alert value, the compressor is controlled to be stopped, and both the refrigerating fan 500 and the freezing fan 400 are controlled to be stopped, so that the temperature of the refrigerating compartment 200 is raised, and when the temperature of the refrigerating compartment is restored to be within the first target range, the normal freezing mode is restored, thereby solving the risk of the refrigerating compartment being excessively low.

In practice, the cold room 200 low temperature warning value may be 0 degrees celsius.

It can be appreciated that the refrigerating chamber 200 of the air-cooled refrigerator does not have frost or ice formation, and after the compressor is controlled to stop, the fan is not required to be controlled to operate to convey air into the refrigerating chamber 200, and the temperature of the refrigerating chamber 200 is automatically balanced.

The control method of the present invention is specifically described below with reference to fig. 2.

Step 200, in the power-on operation process of the refrigerator, it is detected whether a user inputs a first input for switching the freezing chamber 100 from the freezing mode to the refrigerating mode.

Upon receiving the first input, the freezing chamber 100 is controlled to switch from the freezing mode to the refrigerating mode.

Step 210, comparing the freezing chamber temperature with a first target temperature.

When the temperature of the freezing chamber is not greater than the first target temperature, there is a freezing phenomenon in the freezing chamber 100, and the process proceeds to step 220, where the defrosting heater is controlled to operate.

When the temperature of the freezing chamber is higher than the first target temperature, the freezing chamber 100 can be directly controlled according to the refrigerating mode, and when the temperature of the freezing chamber is kept in the second target range, the freezing chamber 100 is in a stop point state, and no refrigeration requirement exists; when the temperature of the freezing chamber is maintained outside the second target range, the freezing chamber 100 is in a start-up point state, and there is a need for cooling.

Accordingly, when the temperature of the refrigerating compartment is maintained within the first target range, the refrigerating compartment 200 is in a stop point state, and there is no refrigeration requirement; when the temperature of the refrigerating chamber is kept outside the first target range, the refrigerating chamber 200 is in the on-point state, and there is a need for refrigeration.

Step 211, comparing the temperature of the refrigerating chamber with the first target range, and determining whether the starting point of the refrigerating chamber 200 is reached.

Step 212, comparing the temperature of the freezing chamber with the second target range, and judging whether the starting point of the freezing chamber 100 is reached.

In step 213, when both the refrigerating chamber 200 and the freezing chamber 100 reach the start-up point, the compressor is controlled to operate for refrigeration, the refrigerating fan 500 rotates at a high duty ratio, the freezing fan 400 rotates at a medium duty ratio, and sufficient cool air is delivered to the refrigerating chamber 200 and the freezing chamber 100, and the refrigerating chamber 200 and the freezing chamber 100 are cooled.

Step 215, when the freezing chamber temperature is within the second target range, the freezing chamber 100 reaches the stop point.

Step 214, controlling the compressor to perform refrigeration, the refrigeration fan 500 rotates at a high duty ratio, and the refrigeration fan 400 rotates at a low duty ratio, so as to cool the refrigeration chamber 200 and effectively prevent wind suck-back.

Step 216, when the refrigerator compartment temperature is within the first target range, the refrigerator compartment 200 also reaches the stop point.

In step 240, the freezing chamber 100 and the refrigerating chamber 200 have no refrigeration requirement, the compressor, the refrigerating fan 500 and the refrigerating fan 500 are controlled to stop, and the temperature of the refrigerating chamber is kept within a first target range and the temperature of the freezing chamber is kept within a second target range.

In step 200, the first input of the user is not received, and the freezing chamber 100 is controlled to operate in the freezing mode.

In the freezing mode, when the temperature of the freezing chamber is kept within the third target range, the freezing chamber 100 is in a stop point state, and no refrigeration requirement exists; when the temperature of the freezing chamber is maintained outside the third target range, the freezing chamber 100 is in a start-up point state, and there is a need for cooling.

Step 230, comparing the temperature of the freezing chamber with the third target range, and determining whether the start point of the freezing chamber 100 is reached.

Step 231, comparing the temperature of the refrigerating chamber with the first target range, and determining whether the starting point of the refrigerating chamber 200 is reached.

In step 232, when the refrigerating chamber 200 and the freezing chamber 100 all reach the start-up point, the compressor is controlled to operate for refrigeration, the refrigerating fan 500 rotates at a high duty ratio, and the freezing fan 400 rotates at a medium duty ratio, so that the refrigerating chamber 200 with a larger volume is cooled preferentially.

Step 233, when the temperature of the refrigerating compartment is within the first target range, the refrigerating compartment 200 reaches the stop point.

Step 234, controlling the compressor to operate for refrigeration, the refrigeration fan 500 rotates at a low duty ratio, and the freezing fan 400 rotates at a high duty ratio, thereby cooling the freezing chamber 100 and effectively preventing wind suck-back.

Step 235, when the freezer compartment temperature is within the third target range, the freezer compartment 100 also reaches the shutdown point.

In the step 240, in the freezing mode, when there is no refrigeration requirement for both the freezing chamber 100 and the refrigerating chamber 200, the compressor, the refrigerating fan 500 and the refrigerating fan 500 are controlled to maintain the temperature of the refrigerating chamber within the first target range and the temperature of the freezing chamber within the third target range.
