Fig. 1 is a method schematic diagram of an embodiment of a control method of a refrigerator provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method includes at least step S110, step S120, and step S130.
Step S110, obtaining a current humidity value of the inner space of the sterilization apparatus.
In one embodiment, a humidity sensor may be disposed in the interior space of the sterilization apparatus for detecting the humidity of the interior space of the sterilization apparatus. The humidity sensor can detect the humidity value of the inner space of the sterilization device in real time.
And step S120, determining the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to a first preset humidity value according to the acquired current humidity value.
Specifically, the dehumidification time required for reducing the humidity of the internal space of the sterilization apparatus from the current humidity value to the first preset humidity value may be determined according to the acquired current humidity value and the size of the space volume of the internal space of the sterilization apparatus. In one embodiment, an image recognition module may be disposed in the internal space of the sterilization apparatus, and the image recognition module may be configured to obtain an image of the internal space of the sterilization apparatus, so as to calculate the spatial volume size V of the internal space of the sterilization apparatus based on the image.
In a specific embodiment, the dehumidification mode specifically includes a first dehumidification mode, a second dehumidification mode, and a third dehumidification mode. Wherein a dehumidification efficiency (dehumidification speed) of the first dehumidification mode is less than a dehumidification efficiency (dehumidification speed) of the second dehumidification mode; the dehumidification efficiency (dehumidification rate) of the second dehumidification mode is less than the dehumidification efficiency (dehumidification rate) of the third dehumidification mode. The dehumidification time Tm required for reducing the humidity of the inner space of the sterilization apparatus from the current humidity value to the first preset humidity value in different dehumidification modes is different. In the first dehumidification mode, the second dehumidification mode and the third dehumidification mode, when dehumidification times required for reducing the humidity of the internal space of the sterilization apparatus from the current humidity value to the first preset humidity value are Tm1, tm2 and Tm3, respectively, tm1> Tm2> Tm3.
Assuming that the humidity in the space per unit volume decreases from rH to rH1 as Δ rH, the amount of humidity to be removed in the space with volume V is Δ rH × V; if the humidity of S1 can be taken away by the first dehumidification mode every minute, the humidity of S2 can be taken away by the second dehumidification mode every minute, the humidity of S3 can be taken away by the third dehumidification mode every minute, and S1 is more than S2 and more than S3, the first dehumidification mode needs to take delta rH V/S1 minutes to finish the reduction of the humidity of the inner space of the sterilization device from the current humidity value rH to a first preset humidity value rH1; similarly, the second dehumidification mode requires Δ rH × V/S2 minutes to complete the reduction of the humidity of the internal space of the sterilization apparatus from the current humidity value rH to the first preset humidity value rH1, and the third dehumidification mode requires Δ rH × V/S3 minutes to complete the reduction of the humidity of the internal space of the sterilization apparatus from the current humidity value rH to the first preset humidity value rH1.
When the current humidity value rH is greater than or equal to a second preset humidity value rH2, that is, rH > = rH2, the electric shock and short circuit risks are high, and a dehumidification mode with higher dehumidification efficiency is required to be used for dehumidification, for example, the second dehumidification mode or the third dehumidification mode; when the current humidity value is greater than the first preset humidity value rH1 and less than the second preset humidity value rH2, that is, rH1< rH2, in the risk of electric shock and short circuit, a dehumidification mode with lower dehumidification efficiency, such as a first dehumidification mode or a second dehumidification mode, may be used for dehumidification. For example, when the humidity rH > = rH2, the humidity is high in electric shock and short-circuit risk, dehumidification is required by a hot air gear or a warm air gear, and the dehumidification time Tm only relates to Tm2 and Tm3 at this time, when the humidity rH1< rH2, dehumidification by a warm air gear or a natural air gear is optional in the electric shock and short-circuit risk, and the dehumidification time Tm only relates to Tm1 and Tm2 at this time, when the humidity 0 is formed by the rH and rH1, the humidity is a safety zone, and dehumidification is not required.
When the current humidity value is larger than a first preset humidity value rH1 and smaller than a second preset humidity value rH2, according to the obtained current humidity value and the space volume, calculating the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to the first preset humidity value rH1 in a first dehumidification mode; and when the current humidity value rH is larger than or equal to a second preset humidity value rH2, calculating the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to a first preset humidity value rH1 in a second dehumidification mode according to the obtained current humidity value and the space volume.
And step S130, controlling the refrigerator to start a sterilization mode and/or a dehumidification mode according to the obtained current humidity value and the determined dehumidification time Tm.
When an electric heating device is further arranged in the inner space of the sterilizing device, the heating power of the electric heating device in the first dehumidification mode is lower than that in the second dehumidification mode; the heating power of the electric heating device in the second dehumidification mode is smaller than that in the third dehumidification mode. For example, the first dehumidification mode is set as natural wind level dehumidification (the electric heating device does not work, the heating power is 0), the second dehumidification mode is set as warm wind level dehumidification, and the third dehumidification mode is set as hot wind level dehumidification. When the warm air damper is operated for dehumidification, the heating power of the electric heating device is smaller than that of the electric heating device when the warm air damper is operated for dehumidification. The sterilization mode is operated once every preset time to sterilize the storage space of the refrigerator.
In one embodiment, the refrigerator is controlled to turn on a sterilization mode and/or a dehumidification mode as follows.
1. And when the current humidity value is greater than or equal to a second preset humidity value rH2, not starting the sterilization mode, and starting the second dehumidification mode or the third dehumidification mode according to a comparison result between the time Ts from the next start of the sterilization mode and the dehumidification time Tm.
If the time Ts from the next starting of the sterilization mode is longer than the dehumidification time Tm, starting a second dehumidification mode; and if the time Ts from the next start of the sterilization mode is less than or equal to the dehumidification time Tm (Ts < = Tm), starting a third dehumidification mode.
After the second dehumidification mode is started, when the current humidity value rH of the inner space of the sterilization device is smaller than a first preset humidity value rH1 (0 and & lt rH = & lt & gt rH 1), the dehumidification is stopped, and when the time for starting the sterilization mode is waited, the sterilization mode is started; after the third dehumidification mode is started, when the current humidity value of the internal space of the sterilization device is larger than a first preset humidity value rH1 and smaller than a second preset humidity value rH2 (rH 1< rH < rH 2) is met, switching to the second dehumidification mode, and when the time for starting the sterilization mode is reached, starting the sterilization mode; and when the current humidity value rH of the inner space of the sterilizing device is smaller than a first preset humidity value rH1 (0-rH = < rH 1), stopping dehumidification.
Specifically, when the humidity value rH in the internal space of the sterilization device satisfies rH > = rH2, the humidity has high risk of electric shock and short circuit, and the sterilization mode needs to be dehumidified as soon as possible without starting the sterilization mode; the second dehumidification mode or the third dehumidification mode is determined to be started according to the time Ts from the next start of the sterilization mode, for example, the second dehumidification mode is warm air dehumidification, and the third dehumidification mode is hot air dehumidification. The sterilization mode is, for example, a plasma sterilization mode.
If Ts is greater than Tm, the dehumidifying time is sufficient, and a warm air gear is selected for dehumidifying; after a warm air gear is started for dehumidification, and until the humidity value meets 0 & lt rH = & lt rH1, a dehumidification fan is closed, and dehumidification is stopped; when the time for starting the sterilization device is up, the plasma sterilization mode is started to start sterilization.
If Ts is less than Tm, the dehumidification time is insufficient, the conflict with degerming is avoided, and hot air grade dehumidification is selected; the method comprises the steps that while dehumidification is carried out on a hot air gear, the humidity value in the inner space of the sterilization device is judged in real time, when the humidity value is reduced to a range of rH1< rH < rH2, dehumidification of the hot air gear is converted into dehumidification of a warm air gear, and meanwhile, when the time for starting the sterilization mode is reached, a plasma sterilization mode is started; and (4) dehumidifying by a warm air gear until the humidity value in the inner space of the sterilizing device meets 0 & lt rH & gt = & lt rH1, and then closing the fan and stopping dehumidifying.
2. When the current humidity value is larger than a first preset humidity value rH1 and smaller than a second preset humidity value rH2 (rH 1< rH < rH2 is met), the sterilization mode is not started, and the first dehumidification mode or the second dehumidification mode is started according to a comparison result of the time Ts from the next start of the sterilization mode and the dehumidification time Tm;
if the time Ts from the next starting of the sterilization mode is longer than the dehumidification time Tm, starting a first dehumidification mode; and if the time Ts from the next start of the sterilization mode is less than or equal to the dehumidification time Tm (Ts < = Tm), starting the second dehumidification mode. After the first dehumidification mode is started, when the current humidity value of the inner space of the sterilization device is smaller than or equal to a first preset humidity value rH1 (0 and & lt rH = & lt < rH 1), the dehumidification is stopped, and when the time for starting the sterilization mode is waited, the sterilization mode is started; after the second dehumidification mode is started, when the current humidity value rH of the inner space of the sterilization device is smaller than a first preset humidity value rH1 (0 < -rH = < rH 1), dehumidification is stopped, and when the time for starting the dehumidification mode is waited, the sterilization mode is started.
Specifically, when the humidity value rH in the inner space of the sterilization apparatus satisfies rH1< rH 2; the plasma sterilization mode is not started temporarily; and determining to start the first dehumidification mode or the second dehumidification mode according to the time Ts from the next start of the sterilization mode, wherein the first dehumidification mode is natural wind grade dehumidification, and the second dehumidification mode is warm wind grade dehumidification. The sterilization mode is, for example, a plasma sterilization mode.
If Ts is greater than Tm, the dehumidification time is sufficient, a natural wind gear is selected for dehumidification, the humidity value in the internal space of the sterilization device is judged in real time while the natural wind dehumidification mode is started for dehumidification, and when the humidity value in the internal space of the sterilization device is reduced to 0-straw (rH) = < rH1, the fan is closed, and the dehumidification function is stopped; when the time for starting the sterilization mode is waited to arrive, the plasma sterilization mode is started.
If Ts is less than Tm, the dehumidification time is insufficient, and a warm air gear is selected for dehumidification; starting a warm air gear for dehumidification, and starting a plasma sterilization mode if the time for starting the sterilization mode is reached; and (3) judging the humidity value in the internal space of the sterilizing device in real time while dehumidifying, and turning off the fan and stopping dehumidifying when the humidity value in the internal space of the sterilizing device is reduced to 0< -rH = < rH1.
3. When the current humidity value rH is smaller than a first preset humidity value rH1 (0 & lt rH = < rH 1), the dehumidification mode is not started, and the sterilization mode is started when the time for starting the sterilization mode is waited.
When the humidity 0-rH 1 is used, the humidity is a safe area and no dehumidification is needed.
The starting of the sterilization mode may specifically include: and starting sterilization modes with different intensities according to the humidity of the storage space of the refrigerator, wherein the higher the humidity of the storage space of the refrigerator is, the higher the sterilization intensity of the started sterilization mode is.
Because the storage chamber spaces with different humidity have different amounts of bacteria, the more humid the bacteria exist, the more favorable the bacteria can be propagated and survive in the space, and the more the bacteria exist; different intensity sterilization modes should be used in different humidity spaces. For example, for plasma sterilization, there are a classification into primary sterilization, secondary sterilization and tertiary sterilization; the degerming intensity is as follows: first-level > second-level > third-level; the sterilization intensity rating includes, but is not limited to, the above ratings.
In order to clearly illustrate the technical solution of the present invention, an execution flow of the control method of the refrigerator provided by the present invention is described below with a specific embodiment.
Fig. 2 is a method schematic diagram of a control method of a refrigerator according to an embodiment of the present invention. As shown in fig. 2, the humidity sensor detects a humidity value rH inside the sterilization apparatus in real time, the camera recognizes a space size V inside the dehumidification module, calculates a time Tm required for reducing the humidity inside the sterilization apparatus from rH to rH1 under different wind speeds under the space V inside the sterilization apparatus, and calculates a dehumidification time required for reducing the humidity inside the sterilization apparatus from a current humidity value to a first preset humidity value rH1 in a first dehumidification mode when rH1< rH 2; when rH is larger than or equal to rH2, the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to the first preset humidity value rH1 in the second dehumidification mode is calculated.
When the humidity value in the internal space of the sterilization device meets rH > = rH2 (the risk of electric shock short circuit is high when the rH > = rH2 is needed to be dehumidified as soon as possible), temporarily not starting a plasma sterilization mode, and determining the grade of starting the dehumidification mode according to the length of time Ts from the next start of the sterilization mode, wherein if Ts > Tm, the dehumidification time is sufficient, a warm air gear is started for dehumidification, and until the humidity value in the sterilization device meets 0 & ltr & gt & ltrH & lt & gt 1, a fan is turned off, dehumidification is stopped, the plasma sterilization mode is waited to be started at the moment, sterilization is started, and the sterilization device starts sterilization with different strengths according to the humidity of a storage room of a refrigerator; if Ts < = Tm, the dehumidifying time is insufficient, and conflicts with the starting of the sterilization mode, the hot air gear is selected for dehumidifying; monitoring the humidity value in the internal space of the sterilization device in real time while dehumidifying by hot air, converting hot air dehumidification into warm air dehumidification when the humidity value rH is reduced to the range of rH1< rH < rH2, and simultaneously starting a sterilization mode such as plasma sterilization if the sterilization mode time comes; and at the moment, dehumidifying by a warm air gear, and turning off a fan and stopping dehumidifying until the humidity value rH meets 0 & lt rH = & lt rH1.

Fig. 3 is a block diagram of a control device of a refrigerator according to an embodiment of the present invention. As shown in fig. 3, the control apparatus 100 includes an acquisition unit 110, a determination unit 120, and a control unit 130.
An obtaining unit 110 for obtaining a current humidity value of the inner space of the sterilization apparatus.
In one embodiment, a humidity sensor may be disposed in the interior space of the sterilization apparatus for detecting the humidity of the interior space of the sterilization apparatus. The humidity sensor can detect the humidity value of the inner space of the sterilization device in real time.
The determining unit 120 is configured to determine, according to the obtained current humidity value, a dehumidification time required to reduce the humidity of the internal space of the sterilization apparatus from the current humidity value to a first preset humidity value.
Specifically, the dehumidification time required for reducing the humidity of the internal space of the sterilization device from the current humidity value to a first preset humidity value is determined according to the acquired current humidity value and the space volume size of the internal space of the sterilization device. In one embodiment, an image recognition module may be disposed in the internal space of the sterilization apparatus, and the image recognition module may be configured to obtain an image of the internal space of the sterilization apparatus, so as to calculate the spatial volume V of the internal space of the sterilization apparatus based on the image.
In a specific embodiment, the dehumidification mode specifically includes a first dehumidification mode, a second dehumidification mode, and a third dehumidification mode. Wherein a dehumidification efficiency (dehumidification speed) of the first dehumidification mode is less than a dehumidification efficiency (dehumidification speed) of the second dehumidification mode; the dehumidification efficiency (dehumidification rate) of the second dehumidification mode is less than the dehumidification efficiency (dehumidification rate) of the third dehumidification mode. The dehumidifying time Tm required for reducing the humidity of the inner space of the sterilizing apparatus from the current humidity value to the first preset humidity value in different dehumidifying modes is different. In the first dehumidification mode, the second dehumidification mode, and the third dehumidification mode, when dehumidification times required to reduce the humidity of the internal space of the sterilization apparatus from the current humidity value to the first preset humidity value are Tm1, tm2, and Tm3, respectively, tm1> Tm2> Tm3.
Assuming that the humidity in the space per unit volume decreases from rH to rH1 as Δ rH, the amount of humidity to be removed in the space with volume V is Δ rH × V; if the first dehumidification mode can take away the humidity of S1 every minute, the second dehumidification mode can take away the humidity of S2 every minute, the third dehumidification mode can take away the humidity of S3 every minute, S1 is more than S2 and less than S3, the first dehumidification mode needs delta rH V/S1 minutes, and the humidity of the inner space of the sterilization device is reduced from the current humidity value rH to a first preset humidity value rH1; similarly, the second dehumidification mode requires Δ rH × V/S2 minutes to complete the reduction of the humidity of the internal space of the sterilization apparatus from the current humidity value rH to the first preset humidity value rH1, and the third dehumidification mode requires Δ rH × V/S3 minutes to complete the reduction of the humidity of the internal space of the sterilization apparatus from the current humidity value rH to the first preset humidity value rH1.
When the current humidity value rH is greater than or equal to a second preset humidity value rH2, that is, rH > = rH2, the electric shock and short circuit risks are high, and a dehumidification mode with higher dehumidification efficiency is required to be used for dehumidification, for example, the second dehumidification mode or the third dehumidification mode; when the current humidity value is greater than the first preset humidity value rH1 and less than the second preset humidity value rH2, that is, rH1< rH2, in the risk of electric shock and short circuit, a dehumidification mode with lower dehumidification efficiency may be used for dehumidification, such as the first dehumidification mode or the second dehumidification mode. For example, when the humidity rH > = rH2, the humidity is high in electric shock and short-circuit risk, dehumidification is required by a hot air gear or a warm air gear, and the dehumidification time Tm only relates to Tm2 and Tm3 at this time, when the humidity rH1< rH2, dehumidification by a warm air gear or a natural air gear is optional in the electric shock and short-circuit risk, and the dehumidification time Tm only relates to Tm1 and Tm2 at this time, when the humidity 0 is formed by the rH and rH1, the humidity is a safety zone, and dehumidification is not required.
When the current humidity value is larger than a first preset humidity value rH1 and smaller than a second preset humidity value rH2, calculating the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to the first preset humidity value rH1 in a first dehumidification mode according to the acquired current humidity value and the acquired space volume; and when the current humidity value rH is larger than or equal to a second preset humidity value rH2, calculating the dehumidification time required for reducing the humidity of the inner space of the sterilization device from the current humidity value to a first preset humidity value rH1 in a second dehumidification mode according to the obtained current humidity value and the space volume.
The control unit 130 is configured to control the refrigerator to start a sterilization mode and/or a dehumidification mode according to the obtained current humidity value and the determined dehumidification time.
When an electric heating device is further arranged in the inner space of the sterilizing device, the heating power of the electric heating device in the first dehumidification mode is lower than that in the second dehumidification mode; the heating power of the electric heating device in the second dehumidification mode is smaller than that in the third dehumidification mode. For example, the first dehumidification mode is set to natural wind level dehumidification (the electric heating device does not work, the heating power is 0), the second dehumidification mode is set to warm wind level dehumidification, and the third dehumidification mode is set to hot wind level dehumidification. When the warm air damper is operated for dehumidification, the heating power of the electric heating device is smaller than that of the electric heating device when the warm air damper is operated for dehumidification. The sterilization mode operates once every preset time to sterilize the storage space of the refrigerator.
In one embodiment, the control unit 130 controls the refrigerator to turn on the sterilization mode and/or the dehumidification mode as follows.

Specifically, when the humidity value rH in the internal space of the sterilization device satisfies rH > = rH2, the humidity has high risk of electric shock and short circuit, and the sterilization mode needs to be dehumidified as soon as possible without starting the sterilization mode; the second dehumidification mode or the third dehumidification mode is determined to be started according to the time Ts from the next start of the sterilization mode, for example, the second dehumidification mode is warm air dehumidification, and the third dehumidification mode is hot air dehumidification. The sterilization mode is, for example, a plasma sterilization mode.
If Ts is greater than Tm, the dehumidification time is sufficient, and a warm air gear is selected for dehumidification; after a warm air gear is started for dehumidification, and until the humidity value meets 0 & ltrH & gt = & lt rH1, a dehumidification fan is closed, and dehumidification is stopped; and starting the plasma sterilization mode to start sterilization when the time for starting the sterilization device is up.

2. When the current humidity value is larger than a first preset humidity value rH1 and smaller than a second preset humidity value rH2 (rH 1< rH < rH2 is met), the sterilization mode is not started, and the first dehumidification mode or the second dehumidification mode is started according to a comparison result of the time Ts from the next start of the sterilization mode and the dehumidification time Tm;

After the first dehumidification mode is started, when the current humidity value of the inner space of the sterilization device is smaller than or equal to a first preset humidity value rH1 (0 < -rH = < rH 1), the dehumidification is stopped, and when the time for starting the sterilization mode is waited, the sterilization mode is started; after the second dehumidification mode is started, when the current humidity value rH of the inner space of the sterilization device is smaller than a first preset humidity value rH1 (0 and & lt rH = & lt rH 1), the dehumidification is stopped, and when the time for starting the sterilization mode is waited, the sterilization mode is started.

If Ts < Tm, the dehumidification time is insufficient, and a warm air gear is selected for dehumidification; starting a warm air gear for dehumidification, and starting a plasma sterilization mode if the time for starting the sterilization mode is reached; and (3) judging the humidity value in the internal space of the sterilization device in real time while dehumidifying, and turning off the fan and stopping dehumidifying when the humidity value in the internal space of the sterilization device is reduced to 0- < -rH = < rH1.
3. When the current humidity value rH is smaller than a first preset humidity value rH1 (0 & lt rH = < rH 1), the dehumidification mode is not started, and the sterilization mode is started when the time for starting the sterilization mode is waited.
When the humidity 0-rH 1 is used, the humidity is a safe area and no dehumidification is needed.
The control unit, starting the sterilization mode, includes: and starting sterilization modes with different intensities according to the humidity of the storage space of the refrigerator, wherein the higher the humidity of the storage space of the refrigerator is, the higher the sterilization intensity of the started sterilization mode is.
