The control device of the refrigerator generally controls the operation state of the refrigerator according to the temperature in the refrigerating chamber. However, when a user puts food having a large moisture content (e.g., soup) in the refrigerating chamber, a large amount of water vapor generated from the food having a large moisture content may be blown off and attached to other food due to the operation of the blower fan in the refrigerator, thereby causing a smell tainting among the food stored in the refrigerator. How to guarantee the quality of food stored in the refrigerator is a problem which needs to be solved urgently at present.

In order to solve the technical problems, the application provides a refrigerator, which determines the type of food (such as chicken soup) in the refrigerator at present according to the humidity detected by a humidity sensor arranged in the refrigerator, and controls an electronic device (at least one of a compressor or a fan) to start or stop running according to the type of the food in the refrigerator, so that the food stored in the refrigerator is prevented from being tainted with odor, the quality of the food in the refrigerator is improved, and the problem of low quality of the food stored in the refrigerator is solved.

Fig. 1 is a schematic structural diagram of a refrigerator 10 provided in the present application. As shown in fig. 1, the refrigerator 10 may include a control device 11 (not shown in fig. 1), a humidity sensor 12, a temperature sensor 13, a compressor 14, a blower fan 15, a door sensing device 16, and an electromagnetic valve 21.

The refrigerator 10 may be a wine cabinet for storing wine, a medicine refrigerator, a blood refrigerator, a medical cryogenic device, a cool box, a commercial display device, or other devices or devices having a cryogenic storage function, which is not limited in the embodiments of the present invention.

Among other things, the humidity sensor 12 is used to detect the humidity inside the refrigerator 10.

The temperature sensor 13 is used to detect the temperature inside the refrigerator 10.

Alternatively, the humidity sensor 12 and the temperature sensor 13 may be integrated and installed inside the refrigerator; the refrigerator door can also be independently installed in the refrigerator, and the embodiment of the application is not limited to this. When the humidity sensor 12 and the temperature sensor 13 are independently installed inside the refrigerator, respectively, the humidity sensor 12 and the temperature sensor 13 may be installed on a right side plate of a refrigerating chamber of the refrigerator, respectively (for example, as shown in fig. 2 a); or on the top plate of the refrigeration compartment of the refrigerator (as shown in figure 2b for example); the device can also be installed at other positions, and the embodiment of the application is not limited to this.

And a compressor 14 for inputting cold air into the refrigerator 10 in an operation state. Specifically, when the refrigeration system of the refrigerator 10 is in operation, the refrigerant flows into the compressor 14, and the compressor 14 performs work on the refrigerant to cause the refrigerant to absorb heat through phase change to generate cold.

The blower fan 15 is used to blow air from the inside of the refrigerator in an operating state. Specifically, after the compressor 14 performs a work on the refrigerant to absorb heat and phase change the refrigerant to generate cold, the fan 15 delivers the cold generated by the refrigerant evaporating phase change to each storage chamber of the refrigerator 10.

The door body sensing device 16 is used for detecting the state of the door body of the refrigerator. The state of the door body of the refrigerator includes: an on state or an off state.

As shown in fig. 3, the control device 11 may be connected to functional modules such as the humidity sensor 12, the temperature sensor 13, the compressor 14, the fan 15, and the door sensing device 16, as shown in fig. 1, and may be configured to control the functional modules such as the compressor 14 and the fan 15, and process data acquired from the functional modules such as the humidity sensor 12, the temperature sensor 13, and the door sensing device 16.

Alternatively, as shown in fig. 4 in conjunction with fig. 1, the refrigerator 10 may further include a display panel 17, a refrigerating chamber 18, a temperature-changing chamber 19, a freezing chamber 20, and an electromagnetic valve 21.

The display panel 17 is used to display the humidity and temperature inside the refrigerator 10.

The solenoid valve 21 is used to control the flow direction of the refrigerant in the refrigerator 10 in response to an instruction from the control device 11. For example, when the refrigerating chamber 18 needs to be cooled down rapidly, the electromagnetic valve 21 controls the refrigerant in the refrigerator 10 to flow into the inner duct of the refrigerating chamber 18 in response to a control command of the control device 11, so as to cool down the refrigerating chamber 18.

The following describes a work flow of the refrigerator 10 provided in the embodiment of the present application.

Since a plurality of time instants are involved in the workflow of the refrigerator 10 provided in the embodiment of the present application, a time line of the plurality of time instants involved in the workflow of the refrigerator 10 provided in the embodiment of the present application will be described first. As shown in fig. 5, a plurality of moments involved in the work flow of the refrigerator 10 provided in the embodiment of the present application include: t is₁Time (corresponding to the fourth time in the embodiment of the present application), T₂Time of day (corresponding to the second embodiment of the present application)Three moments), T₃Time (corresponding to the fifth time in the embodiment of the present application), T₄Time (corresponding to the first time in the embodiment of the present application), T₅Time (corresponding to the second time in the embodiment of the present application). The above five moments are ordered according to the sequence (corresponding to the direction of the arrow in fig. 5) as follows: t is₁Time, T₂Time, T₃Time, T₄Time, T₅The time of day. Wherein, T₁The moment is the earliest moment in the five moments; t is₅The time is the latest time among the five times.

The first embodiment is as follows:

the present application provides a control method of a refrigerator 10, which is applied to the refrigerator 10, and as shown in fig. 6, with reference to fig. 1, fig. 2a, fig. 2b, fig. 3, fig. 4, and fig. 5, the control method includes: S601-S610.

S601, when the first state detected by the door body sensing device 16 is determined to be the opening state, the control device 11 controls the humidity sensor 12 to be in the T state₁The humidity and temperature sensor 13 detected at the moment is at T₁And determining a first humidity threshold value, a second humidity threshold value, a first temperature threshold value and a second temperature threshold value according to the detected temperature at the moment.

Wherein, the first state is that the door body induction device 16 is at T₂The door state of the refrigerator 10 detected at any time. Humidity sensor 12 is at T₁The humidity detected at that time is the third humidity. Temperature sensor 13 at T₁The temperature detected at that time is the third temperature.

Specifically, the humidity sensor 12 periodically detects the humidity in the refrigerator 10. Accordingly, the temperature sensor 13 periodically detects the temperature inside the refrigerator 10. Optionally, the period in which the humidity sensor 12 detects the humidity in the refrigerator 10 may be the same as or different from the period in which the temperature sensor 13 detects the temperature in the refrigerator 10, and this embodiment of the present application does not limit this.

When the control device 11 determines that the door body sensing device 16 is at T₂When the first state of the refrigerator 10 is detected to be the open state at any time, it indicates that the door of the refrigerator 10 is at T₂The moment is already on. At this time, the user has the possibility ofFood can be stored into the refrigerator 10. Therefore, before the door of the refrigerator 10 is opened (i.e., T)₂T before time₁At that time), the humidity and temperature inside the refrigerator 10 are the temperature and humidity required to satisfy the food. In this case, the control device 11 determines the third humidity detected by the humidity sensor 12 and the third temperature detected by the temperature sensor 13.

After that, the control device 11 determines the first humidity threshold value and the second humidity threshold value according to the third humidity. Wherein the first humidity threshold and the second humidity threshold are humidity thresholds required for food stored in the refrigerator 10. The second humidity threshold is less than the first humidity threshold.

For example, the first humidity threshold may be 1.2 times the third humidity, and the second humidity threshold may be the third humidity. On the premise that the second humidity threshold is smaller than the first humidity threshold, the first humidity threshold and the second humidity threshold may also be other preset multiples of the third humidity, which is not limited in the embodiment of the present application.

Accordingly, the control device 11 determines the first temperature threshold value and the second temperature threshold value according to the third temperature. Wherein the first temperature threshold and the second temperature threshold are temperature thresholds required for food stored in the refrigerator 10. The second temperature threshold is greater than the first temperature threshold.

For example, the first temperature threshold may be the third temperature, and the second temperature threshold may be 1.2 times the third temperature. On the premise that the second temperature threshold is greater than the first temperature threshold, the first temperature threshold and the second temperature threshold may also be other preset multiples of the third temperature, which is not limited in the embodiment of the present application.

S602, when the second state detected by the door body sensing device 16 is determined to be the closed state, the control device 11 judges that the humidity sensor 12 is in T state₄Whether the humidity detected at the moment is greater than a first humidity threshold.

Wherein, the second state is that the door body induction device 16 is at T₃The door state of the refrigerator 10 detected at any time. Humidity sensor 12 is at T₄The humidity detected at that time is the first humidity.

Since the control device 11 determines the doorBody sensing device 16 is at T₂When the first state of the refrigerator 10 is detected to be the open state at any time, external factors (such as the indoor temperature and humidity) have a great influence on the humidity in the refrigerator 10, and therefore, when the control device 11 determines that the door sensing device 16 is at T₃When the second state of the refrigerator 10 is detected to be the closed state at any time, at this time, the door of the refrigerator 10 is in the closed state and at T₃T before time₂At that time, the door of the refrigerator 10 is opened, and the user may store food in the refrigerator 10, so that the control device 11 is at T according to the humidity sensor 12₄The humidity detected at the moment determines the kind of food stored in the refrigerator 10.

Specifically, when the control device 11 determines that the door state detected by the door sensing device 16 is the closed state and the first humidity detected by the humidity sensor 12 is greater than the first humidity threshold, the first humidity is detected at T₄At the moment the humidity in the refrigerator 10 is high, the control device 11 therefore determines T₄At this time, soup food is stored in the refrigerator 10, and S603 is executed. When the control device 11 determines that the door state detected by the door sensing device 16 is the closed state and the first humidity detected by the humidity sensor 12 is not greater than the first humidity threshold value, the first humidity is detected at T₄At the moment the humidity in the refrigerator 10 is low, the control device 11 therefore determines T₄At this time, the non-soup food is stored in the refrigerator 10, and S607 is executed.

Optionally, in order to ensure that the control device 11 can more accurately determine the type of food stored in the refrigerator 10 according to the humidity detected by the humidity sensor 12, when it is determined that the second state detected by the door sensing device 16 is the closed state, the control device 11 determines whether a plurality of humidities detected by the humidity sensor 12 in the third preset time period are greater than the first humidity threshold.

For example, when it is determined that the second state detected by the door body sensing device 16 is the closed state, the control device 11 determines that the humidity sensor 12 periodically detects three humidity values (humidity a, humidity B and humidity C) within a third preset time period, and the humidity a, the humidity B and the humidity C are all greater than the first humidity threshold value, and then may determine T₄The soup food is stored in the refrigerator 10 at any timeA compound (I) is provided. Accordingly, when humidity A, humidity B, and humidity C are less than the first humidity threshold, T may be determined₄Non-soup food is stored in the refrigerator 10 at that time.

S603, the control device 11 controls the fan 15 to stop running and controls the compressor 14 to start running; after determining that the operation time period of the compressor 14 is greater than or equal to the first preset time period, controlling the fan 15 to start operation.

When determining T₄At the moment, soup food is stored in the refrigerator 10 (namely, the first humidity is greater than the first humidity threshold), and the humidity in the refrigerator 10 is relatively high, so that the control device 11 controls the fan 15 to stop running, and the fan 15 is prevented from blowing water vapor on the soup food to other food, so that mutual tainting of the food is prevented. At this time, the control device 11 controls the compressor 14 to start operation, and inputs cold air into the refrigerator 10, so that the temperature in the refrigerator 10 is reduced. When the operation time of the compressor 14 is greater than or equal to the first preset time period, the temperature in the refrigerator 10 is reduced to the preset temperature, and the water vapor on the surface of the soup food is condensed into a water film. In this case, the air blown by the fan 15 will not blow the water vapor on the soup food to other food, so the control device 11 controls the fan 15 to start up and operate, and blows away the cold air input from the compressor 14 to the inside of the refrigerator 10, thereby increasing the cooling rate.

S604, after the fan 15 is controlled to start running, the control device 11 judges whether the running time of the fan 15 is less than a second preset time period.

When it is determined that the operation time period of the fan 15 is less than the second preset time period, S605 is executed. When it is determined that the operation time period of the fan 15 is not less than the second preset time period, S606 is executed.

S605, the control device 11 determines that the temperature sensor 13 is at T₅Whether the temperature detected at that moment is less than a first temperature threshold and the humidity sensor 12 is at T₅Whether the humidity detected at the moment is less than a second humidity threshold.

Wherein the temperature sensor 13 is at T₅The temperature detected at that time is the first temperature. Humidity sensor 12 is at T₅The sensed humidity at the time point is the second humidity.

When the control device 11 determines that the first temperature detected by the temperature sensor 13 is less than the first temperature threshold and the second humidity detected by the humidity sensor 12 is less than the second humidity threshold, it indicates that the temperature in the refrigerator 10 has satisfied the temperature required for the food and the humidity in the refrigerator 10 has satisfied the humidity required for the food, S606 is executed. Otherwise, S604 is executed.

And S606, the control device 11 controls the compressor 14 and the fan 15 to stop running.

When it is determined that the first temperature detected by the temperature sensor 13 is less than the first temperature threshold value and the second humidity detected by the humidity sensor 12 is less than the second humidity threshold value, it indicates that the temperature in the refrigerator 10 has satisfied the temperature required for the food and the humidity in the refrigerator 10 has satisfied the humidity required for the food, and therefore, the control device 11 controls the compressor 14 and the blower fan 15 to stop operating.

When it is determined that the operation time period of the fan 15 is not less than the second preset time period, the control device 11 controls the compressor 14 and the fan 15 to stop operating in order to prevent at least one of the temperature sensor 13, the humidity sensor 12, or the control device 11 from malfunctioning, thereby causing the compressor 14 and the fan 15 to operate continuously.

And S607, the control device 11 controls the compressor 14 to start and operate and controls the fan 15 to start and operate.

When determining T₄At the moment that the non-soup food is stored in the refrigerator 10 (i.e. the first humidity is less than the first humidity threshold), the control device 11 controls the compressor 14 to start operation, and inputs cold air into the refrigerator 10, so that the temperature in the refrigerator 10 is reduced. Because no water vapor exists on the surface of the non-soup food, the control device 11 controls the fan 15 to start and operate, and blows the cold air input by the compressor 14 to the inside of the refrigerator 10, so that the cooling rate is improved.

And S608, after the compressor 14 and the fan 15 are controlled to start running, the control device 11 judges whether the running time of the compressor 14 and the fan 15 is less than a second preset time period.

When it is determined that the operating time period of the compressor 14 and the fan 15 is less than the second preset time period, S609 is performed. When it is determined that the operating time periods of the compressor 14 and the fan 15 are not less than the second preset time period, S610 is performed.

S609, the control device 11 judges that the temperature sensor 13 is at T₅Whether the temperature detected at that moment is less than a first temperature threshold.

Wherein the temperature sensor 13 is at T₅The temperature detected at that time is the first temperature.

When the control device 11 determines that the first temperature detected by the temperature sensor 13 is less than the first temperature threshold, indicating that the temperature inside the refrigerator 10 has satisfied the temperature required for the food, S610 is performed. Otherwise, S608 is executed.

And S610, the control device 11 controls the compressor 14 and the fan 15 to stop running.

When it is determined that the first temperature detected by the humidity sensor 12 is less than the first temperature threshold, it indicates that the temperature in the refrigerator 10 has satisfied the temperature required for the food, and the kind of the food stored in the refrigerator 10 is non-soup food regardless of the humidity in the refrigerator 10, and therefore, the control device 11 controls the compressor 14 and the fan 15 to stop operating.

When it is determined that the operation time period of the compressor 14 and the fan 15 is not less than the second preset time period, the control device 11 controls the compressor 14 and the fan 15 to stop operating in order to prevent at least one of the temperature sensor 13, the humidity sensor 12, or the control device 11 from malfunctioning, thereby causing the compressor 14 and the fan 15 to operate continuously.

Example two:

in the above embodiment, the control device 11 is operated at T according to the humidity sensor 12₄The humidity detected at the moment determines the kind of food stored in the refrigerator 10. In another possible implementation, the control device 11 may be adapted to determine the humidity at T from the humidity sensor 12₄The humidity and temperature sensor 13 detected at the moment in time is at T₄The temperature detected at that moment determines the kind of food stored in the refrigerator 10. Therefore, the present application provides a control method of a refrigerator 10, which is applied to the refrigerator 10, and is shown in fig. 7 in conjunction with fig. 1, fig. 2a, fig. 2b, fig. 3, fig. 4 and fig. 5, and includes: S701-S712.

S701, controlling when the first state detected by the door body sensing device 16 is determined to be the opening stateDevice 11 is responsive to humidity sensor 12 at T₁The humidity and temperature sensor 13 detected at the moment is at T₁And determining a first humidity threshold value, a second humidity threshold value, a first temperature threshold value and a second temperature threshold value according to the detected temperature at the moment.

S701 is consistent with S601 in the first embodiment, and reference may be specifically made to the description in S601, which is not repeated herein.

S702, when the second state detected by the door body sensing device 16 is determined to be the closed state, the control device 11 judges that the humidity sensor 12 is in the T state₄Whether the humidity detected at that time is greater than a first humidity threshold value, and the control device 11 determines that the temperature sensor 13 is at T₄Whether the temperature detected at that moment is greater than a second temperature threshold.

Wherein, the second state is that the door body induction device 16 is at T₃The door state of the refrigerator 10 detected at any time. Humidity sensor 12 is at T₄The humidity detected at that time is the first humidity. Temperature sensor 13 at T₄The temperature detected at that time is the second temperature.

Because the control device 11 determines that the door body sensing device 16 is at T₂When the first state of the refrigerator 10 is detected to be the open state at any time, external factors (such as the indoor temperature and humidity) have a great influence on the humidity in the refrigerator 10, and therefore, when the control device 11 determines that the door sensing device 16 is at T₃When the second state of the refrigerator 10 is detected to be the closed state at any time, at this time, the door of the refrigerator 10 is in the closed state and at T₃T before time₂At that time, the door of the refrigerator 10 is opened, and the user may store food in the refrigerator 10, so that the control device 11 is at T according to the humidity sensor 12₄The humidity and temperature sensor 13 detected at the moment in time is at T₄The temperature detected at that moment determines the kind of food stored in the refrigerator 10.

Specifically, when the control device 11 determines that the door state detected by the door sensing device 16 is the closed state, the first humidity is greater than the first humidity threshold, and the second temperature is greater than the second temperature threshold, at this time, the humidity in the refrigerator 10 is greater, and the temperature is greater, so that the control device 11 determines T₄At this time, hot food such as soup is stored in the refrigerator 10, and S703 is executed.

When the control device 11 determines that the door state detected by the door sensing device 16 is the closed state, the first humidity is greater than the first humidity threshold, and the second temperature is less than the second temperature threshold, at this time, the humidity in the refrigerator 10 is greater, and the temperature is lower, so that the control device 11 determines T₄At this time, the refrigerator 10 stores therein soup-like cold foods, and S704 is executed.

When the control device 11 determines that the door state detected by the door sensing device 16 is the closed state, the first humidity is smaller than the first humidity threshold value, and the second temperature is greater than the second temperature threshold value, at this time, the humidity in the refrigerator 10 is smaller, and the temperature is higher, so the control device 11 determines T₄At this time, the non-soup hot food is stored in the refrigerator 10, and S705 is executed.

When the control device 11 determines that the door state detected by the door sensing device 16 is the closed state, the first humidity is smaller than the first humidity threshold value, and the second temperature is smaller than the second temperature threshold value, at this time, the humidity in the refrigerator 10 is smaller, and the temperature is smaller, so that the control device 11 determines T₄At this time, non-soup cold food is stored in the refrigerator 10, and S706 is executed.

Optionally, in order to ensure that the control device 11 can more accurately determine the type of food stored in the refrigerator 10 according to the humidity detected by the humidity sensor 12 and the temperature detected by the temperature sensor 13, when it is determined that the second state detected by the door sensing device 16 is the closed state, the control device 11 determines whether a plurality of humidities detected by the humidity sensor 12 in the third preset time period are greater than the first humidity threshold value, and whether a plurality of temperatures detected by the temperature sensor 13 in the third preset time period are greater than the second temperature threshold value.

For example, when it is determined that the second state detected by the door sensing device 16 is the closed state, the control device 11 determines that the humidity sensor 12 periodically detects three humidity values (humidity a, humidity B, and humidity C) during a third preset time period and the temperature sensor 13 periodically detects three temperature values (temperature a, temperature B, and temperature C) during the third preset time period. When humidity A, humidity B and humidityWhen the temperature C is greater than the first humidity threshold value and the temperatures a, B, and C are greater than the second temperature threshold value, the control device 11 determines T₄Hot food such as soup is stored in the refrigerator 10 at all times. When the humidity a, the humidity B, and the humidity C are all greater than the first humidity threshold value, and the temperature a, the temperature B, and the temperature C are all less than the second temperature threshold value, the control device 11 determines T₄The refrigerator 10 stores cold food such as soup at any time. When the humidity a, the humidity B, and the humidity C are all less than the first humidity threshold value, and the temperature a, the temperature B, and the temperature C are all greater than the second temperature threshold value, the control device 11 determines T₄The non-soup hot food is stored in the refrigerator 10 at that time. When the humidity a, the humidity B, and the humidity C are all less than the first humidity threshold value, and the temperature a, the temperature B, and the temperature C are less than the second temperature threshold value, the control device 11 determines T₄The refrigerator 10 is stored with non-soup cold food at all times.

S703, the control device 11 controls the fan 15 to stop running and controls the compressor 14 to start running at the maximum rotating speed of the compressor 14; after determining that the operation time period of the compressor 14 is greater than or equal to the first preset time period, controlling the fan 15 to start operation at the maximum rotation speed of the fan 15.

When determining T₄The hot food of soup (that is, the second temperature is greater than the second temperature threshold value, and the second temperature is greater than the second temperature threshold value) has been deposited in the refrigerator 10 at any moment, because the humidity in the refrigerator 10 is great, consequently, controlling means 11 control fan 15 stop the operation, prevent that fan 15 from blowing on the steam on the hot food of soup to other food, and then prevent to have a bad smell mutually between the food. Since the temperature inside the refrigerator 10 is also large, the control device 11 controls the compressor 14 to start operation at the maximum rotation speed of the compressor 14, and rapidly inputs cold air into the inside of the refrigerator 10, so that the temperature inside the refrigerator 10 is rapidly decreased. When the operation time of the compressor 14 is greater than or equal to the first preset time period, the temperature in the refrigerator 10 is reduced to the preset temperature, and the water vapor on the surface of the hot soup food is condensed into a water film. In this case, the air blown by the fan 15 does not blow the water vapor on the hot soup food to other food, so the control device 11 controls the fan 15 to start up and operate at the maximum rotation speed of the fan 15 to blow the cold air input from the compressor 14 to the inside of the refrigerator 10 to be dissipatedThe rate of temperature reduction is high.

S704, the control device 11 controls the fan 15 to stop running and controls the compressor 14 to start running at a first rotating speed; after determining that the operation time period of the compressor 14 is greater than or equal to the first preset time period, controlling the fan 15 to start operating at the second rotating speed.

Wherein the first rotational speed is less than the maximum rotational speed of the compressor 14. The second rotational speed is less than the maximum rotational speed of the fan 15.

When determining T₄The cold food of hot soup (that is, the second temperature is greater than the second temperature threshold value, and the second temperature is less than the second temperature threshold value) has been deposited in refrigerator 10 at any moment, because the humidity in refrigerator 10 is great, consequently, controlling means 11 control fan 15 stop the operation, prevent that fan 15 from blowing the steam on the hot food of hot soup to other food on, and then prevent to have a bad smell mutually between the food. Since the temperature in the refrigerator 10 is low, it is not necessary to cool the refrigerator 10 quickly, and therefore, in order to save energy and power, the control device 11 controls the compressor 14 to start operating at the first rotation speed, and inputs cold air into the refrigerator 10, so that the temperature in the refrigerator 10 is lowered. When the operation time of the compressor 14 is greater than or equal to the first preset time period, the temperature in the refrigerator 10 is reduced to the preset temperature, and the water vapor on the surface of the soup cold food is condensed into a water film. In this case, the air blown by the fan 15 does not blow the water vapor on the cold food such as soup to other food, so that the controller 11 controls the fan 15 to start operating at the second rotation speed to blow away the cold air input from the compressor 14 to the inside of the refrigerator 10 to increase the cooling rate, also for energy saving and power saving.

S705, the control device 11 controls the compressor 14 to start up and operate at the maximum rotation speed of the compressor 14, and controls the fan 15 to start up and operate at the maximum rotation speed of the fan 15.

When determining T₄At the moment that the non-soup hot food is stored in the refrigerator 10 (i.e. the first humidity is less than the first humidity threshold, and the second temperature is greater than the second temperature threshold), because no water vapor is on the surface of the non-soup hot food and the temperature in the refrigerator 10 is high, the control device 11 controls the compressor 14 to start and operate at the maximum rotating speed of the compressor 14, and quickly inputs cold air into the refrigerator 10, so that the refrigerator 10 can store the non-soup hot food thereinThe temperature decreases rapidly. The control device 11 controls the fan 15 to start and operate at the maximum rotating speed of the fan 15, and blows the cold air input into the refrigerator 10 by the compressor 14, so that the cooling rate is improved.

And S706, the control device 11 controls the compressor 14 to start and operate at the first rotating speed, and controls the fan 15 to start and operate at the second rotating speed.

When determining T₄At any moment, non-soup cold food is stored in the refrigerator 10 (i.e. the first humidity is less than the first humidity threshold, and the second temperature is less than the second temperature threshold), because there is no water vapor on the surface of the non-soup cold food, and the temperature in the refrigerator 10 is low, it is not necessary to rapidly cool the refrigerator 10, therefore, in order to save energy and electricity, the control device 11 controls the compressor 14 to start and operate at the first rotation speed, and inputs cold air into the refrigerator 10, so as to reduce the temperature in the refrigerator 10. The control device 11 controls the fan 15 to start and operate at the second rotation speed, and blows the cold air input by the compressor 14 to the inside of the refrigerator 10, so that the cooling rate is increased.

And S707, after controlling the fan 15 to start running at the maximum rotating speed of the fan 15 or controlling the fan 15 to start running at the second rotating speed, the control device 11 judges whether the running time of the fan 15 is less than a second preset time period.
