The illumination is a necessary condition for the growth maintenance and the synthesis of various nutrients of fruits and vegetables. The fresh fruits and vegetables still have certain life activity after picking, and can continue to breathe in the storage process of the refrigerator, so that the nutrients of the fruits and vegetables are consumed, and the nutritional value of the fruits and vegetables is gradually reduced. In recent years, the demands of people on fruits and vegetables with high quality and high nutrition are stronger. Therefore, the fruit and vegetable nutrition components are improved to the greatest extent while preserving the fruits and vegetables.

At present, a technology for preserving fruits and vegetables by adopting specific light waves is applied to the refrigerator industry. However, the related art focuses more on prolonging the fresh-keeping period and maintaining the nutrition not to be lost. The scheme focuses the reverse growth of the picked fruits and vegetables, realizes the improvement of various nutrients and ensures that the fruits and vegetables are more nutritious. In addition, tropical fruits are delicious, but are difficult to store. If stored at normal temperature, the tropical fruits have short fresh-keeping period, can not be eaten and decay, and waste is caused; if the fruits are stored in a common refrigeration way (4-5 ℃), the tropical fruits in the green ripening period cannot be cooked, are easy to be damaged by cold, and have poor edible mouthfeel.

Based on the above, the embodiment of the invention provides a control method of a refrigerator, a controller, the refrigerator and a storage medium. The refrigerator comprises a fresh-keeping drawer, wherein the fresh-keeping drawer comprises an illumination assembly, and the color temperature irradiated by the illumination assembly comprises a first color temperature and a second color temperature. The control method of the refrigerator includes, but is not limited to, the steps of: when the fresh-keeping drawer is in a closed state, opening the illumination assembly and recording the continuous operation time of the illumination assembly; the illumination component alternately irradiates the first color temperature and the second color temperature within the continuous operation time; and adjusting the illumination intensity of the illumination assembly according to the continuous operation time length and the preset operation condition.

It can be understood that the related art generally adopts a single color temperature or multiple color temperatures to keep fruits and vegetables fresh by continuous irradiation, so that the fresh-keeping time can be prolonged, but the nutrition loss of fruits and vegetables is larger. The embodiment of the invention can stimulate the growth of fruits and vegetables through the alternate irradiation of different color temperatures, thereby improving the nutritional ingredients of the fruits and vegetables. In addition, the temperature rise in the fresh-keeping drawer can be controlled by adjusting the illumination intensity through the continuous operation time of illumination, so that the balance of the fruit and vegetable cultivation and fresh-keeping quality is ensured.

Those skilled in the art will appreciate that the device structure shown in FIG. 1 is not limiting of system architecture platform 1000 and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.

In the system architecture platform 1000 shown in fig. 1, a processor 1001 may be used to call a control program of a refrigerator stored in a memory 1002, thereby implementing a control method of the refrigerator.

Based on the hardware structure of the system architecture platform 1000 described above, various embodiments of the refrigerator of the present invention are presented.

In particular, the fresh food drawer of the present invention includes an illumination assembly for use in, and in, a refrigerated compartment of a refrigerator, which may refer to a broad sense of refrigerated storage devices such as refrigerators, freezers, refrigerated cabinets. In further detail, the refrigerator of the embodiment of the present invention includes, but is not limited to, a fresh food drawer, a fresh food compartment, and a controller. Wherein the fresh food drawer is disposed in the refrigerator compartment, the fresh food drawer comprises an illumination assembly, the color temperature illuminated by the illumination assembly comprises a first color temperature and a second color temperature, and the controller may comprise a processor 1001 and a memory 1002 as shown in fig. 1. It should be noted that the illumination assembly may be a single light source or an integrated plurality of light sources. In the case of a single light source, the color temperature of the illumination is changed by changing the illumination frequency of the light source. In the case of a plurality of light sources, for example two light sources, one light source emits a color temperature. The color temperature includes red, orange, blue or other color temperatures.

It should be noted that the first color temperature and the second color temperature of the embodiment of the present invention are optimal for red and blue. In a specific example, the illumination assembly is an LED red-blue dual-core lamp panel.

In another embodiment, a fresh food drawer includes a lighting assembly; the fresh-keeping shell is provided with a closed accommodating space; the air interchanger is arranged on the fresh-keeping shell and can enable the containing space to be communicated with or isolated from the refrigerating compartment. In another embodiment, a fresh food drawer includes a lighting assembly; the fresh-keeping shell is provided with a closed accommodating space; the air interchanger is arranged on the fresh-keeping shell and can enable the accommodating space to be communicated with or isolated from the refrigerating compartment; a temperature sensor. In particular, to achieve communication or isolation of the receiving space from the refrigerated compartment, the ventilation means may select an electronically controlled one-way valve or a mechanically controlled device, for example in some embodiments a damper driven by a drive means, the damper controllably opening or closing communication between the receiving space and the refrigerated compartment.

Based on the above-mentioned module hardware structure of the refrigerator, various embodiments of the control method of the refrigerator of the present invention are presented.

It should be noted that, the color temperature is a unit of measure indicating that the light includes color components. Embodiments of the present invention use color temperature to represent different colors of light. For example, a first color temperature represents red light and a second color temperature represents blue light. Theoretically, blackbody temperature refers to the color that an absolute blackbody assumes after heating from absolute zero (-273 ℃). After being heated, the black body gradually turns from black to red, turns yellow and turns white, and finally emits blue light. When heated to a certain temperature, the spectral components contained in the light emitted by the black body are called the color temperature at this temperature, and the measurement unit is "K" (kelvin). If a light source emits light having the same spectral composition as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. If the color of the light emitted by the 100W bulb is the same as that of the absolute blackbody at 2527 ℃, the color temperature of the light emitted by the bulb is: (2527+273) k=2800k.

As shown in fig. 2, fig. 2 is a flowchart of a control method of a refrigerator according to an embodiment of the present invention. The control method of the refrigerator according to the embodiment of the invention includes, but is not limited to, step S100 and step S200.

Step S100, when the fresh-keeping drawer is in a fresh-increasing mode and a closed state, starting the illumination assembly and recording the continuous operation duration of the illumination assembly; wherein the illumination assembly alternately illuminates the first color temperature and the second color temperature during the continuous operation period.

Specifically, the operation modes of the fresh-keeping drawer comprise a fresh-increasing mode and a ripening mode, and the closing condition of the fresh-keeping drawer comprises a closing state and an opening state. When the fresh-keeping drawer is in the fresh-increasing mode and the closed state, the fresh-keeping drawer is in the fresh-increasing working state, and the illumination assembly is required to be started for illumination. Taking fruits and vegetables placed in the fresh-keeping drawer as an example, the photosynthesis can be promoted by irradiating the fruits and vegetables, and the nutritional ingredients of the fruits and vegetables can be improved. In addition, the embodiment of the invention further stimulates the growth of fruits and vegetables by alternately irradiating the first color temperature and the second color temperature in the continuous operation time of the illumination component, thereby improving the nutritional ingredients of the fruits and vegetables.

It should be noted that the operation mode may be specified by a user, for example, the user places the fruits and vegetables to be preserved in the preservation drawer, and selects the operation mode to be the freshness-enhancing mode. Or, the corresponding operation mode is determined by identifying fruits and vegetables in the fresh-keeping drawer without being specified by a user. The closing condition can be detected by a sensor to determine whether the fresh-keeping drawer is in a closed state or an open state. The method for detecting the closing condition of the fresh-keeping drawer is not particularly limited in the embodiment of the invention.

Step S200, adjusting the illumination intensity of the illumination assembly according to the continuous operation duration and the preset operation condition.

Specifically, the preset operation condition may refer to an operation duration threshold, and the illumination intensity of the illumination assembly may be adjusted according to a comparison result of the continuous operation duration and the preset operation condition. For example, if the continuous run length is less than or equal to the run length threshold, the illumination intensity of the illumination assembly is increased or maintained. If the continuous operation time length is greater than the operation time length threshold value, the illumination intensity of the illumination assembly is reduced, so that heat generated by illumination is reduced, and further, the temperature rise in the fresh-keeping drawer is reduced. Therefore, the embodiment of the invention can control the temperature rise in the fresh-keeping drawer by adjusting the illumination intensity through the continuous operation time of illumination, and ensure the balance of the fruit and vegetable raising and fresh-keeping quality. It is understood that nutrition of the picked fruits and vegetables is continuously lost due to respiration. The embodiment of the invention can realize the nutrition improvement of the picked fruits and vegetables: through the first color temperature (red light) and the second color temperature (blue light) which are alternately opened, nutrient components such as anthocyanin, polyphenol, chlorophyll, soluble solids and the like in fruits and vegetables are improved, meanwhile, the temperature rise in the fresh-keeping drawer can be controlled to be smaller than a temperature rise threshold (0.5 ℃) by adjusting the illumination intensity through the continuous operation duration of illumination, and the balance of the fruit and vegetable raising and fresh-keeping quality is ensured.

In a specific example, if the continuous operation time period is greater than the operation time period threshold, the illumination intensity of the illumination assembly is adjusted to be less than a preset first illumination intensity threshold, and at least the preset first stay time period is maintained. It should be noted that, the fresh-keeping drawer is placed in the cold-storage room, the temperature of the cold-storage room is about 4 to 5 ℃, the illumination component obtains a certain environmental temperature rise in the threshold value of the operation time after being opened, after the continuous operation time is longer than the threshold value of the operation time, the illumination component irradiates the heat generated by the first stay time under the first illumination intensity threshold value and can not heat the fresh-keeping drawer, namely the temperature in the fresh-keeping drawer can be continuously reduced under the first illumination intensity threshold value until the temperature is reduced to the preset cold-storage temperature of the cold-storage room. In a specific example, the run length threshold is 10 minutes, the first illumination intensity threshold is zero, and the first dwell time is 50 minutes.

It should be noted that, during the first stay period, if the fresh-keeping drawer is detected to be switched from the open state to the closed state, the illumination assembly is restarted. And restarting the illumination assembly if the fresh-keeping drawer is in a closed state after the first stay time is over. The environmental temperature rise in the embodiment of the invention refers to the temperature rise value in the fresh-keeping drawer. For example, the fresh-keeping drawer has a storage space therein, and the ambient temperature rise refers to a temperature rise value in the storage space.

As shown in fig. 3, the continuous operation duration of step S100 is obtained by the steps of:

step S210, recording a first operation time length of the illumination assembly for irradiating a first color temperature and a second operation time length of the illumination assembly for irradiating a second color temperature in the process of continuously emitting light by the illumination assembly;

step S220, obtaining the continuous operation duration according to the first operation duration and the second operation duration.

Specifically, after the illumination assembly is turned on, the illumination assembly always emits light continuously. And in the process of light emission, alternately irradiating the first color temperature and the second color temperature, and obtaining the continuous operation time according to the obtained sum of the first operation time and the second operation time. The first operation time length and the second operation time length may be equal or different. In a specific example, after the illumination component is turned on, the first color temperature is irradiated for a first operation duration, and then the second color temperature is irradiated for a second operation duration.

In another specific example, the first color temperature and the second color temperature are respectively irradiated for a plurality of intermediate time periods, and the first operation time period and the second operation time period are respectively obtained according to the sum of the plurality of intermediate time periods.

As shown in fig. 4, after the illumination assembly is turned on in step S100, the control method of the embodiment of the present invention further includes, but is not limited to, steps S310 to S320.

Step S310, obtaining an environment heating value of the fresh-keeping drawer;

step S320, adjusting the illumination intensity of the illumination component according to the environmental temperature rise value.

Specifically, after the illumination component is started, the increase of the nutritional ingredients of the fruits and vegetables can be stimulated by illumination. But the illumination brings heat to raise the ambient temperature in the fresh-keeping drawer. The high ambient temperature can affect the fresh-keeping effect of fruits and vegetables, so that the embodiment of the invention adjusts the illumination intensity of the illumination assembly according to the ambient temperature rise value to adjust the increased heat, thereby realizing the control of the ambient temperature of the fresh-keeping drawer and ensuring the fresh-keeping effect.

In step S320, when the environmental temperature rise value is greater than the preset temperature rise threshold, the illumination assembly is turned off. In an example, after the illumination assembly is turned off, the closing time is recorded, at least a preset closing time threshold of the illumination assembly is required to be turned off, and after the closing time threshold, if the fresh-keeping drawer is in a closed state, the illumination assembly is restarted.

As shown in fig. 5, the ambient temperature increase value at step S310 is obtained by the steps of:

step S410, obtaining a first color temperature illumination intensity of a first color temperature and a second color temperature illumination intensity of a second color temperature;

step S420, obtaining a first increased heat according to the first color temperature illumination intensity and the first operation duration;

step S430, obtaining a second increased heat according to the second color temperature illumination intensity and the second operation duration;

in step S440, the environmental heating value is obtained according to the first increased heat and the second increased heat.

Specifically, the product of the illumination intensity and the operation time period may determine the amount of heat added, so that the total amount of heat added may be determined from the sum of the first amount of heat added and the second amount of heat added, so that the ambient temperature increase value is determined from the total amount of heat added. In addition, the environmental heating value is determined according to the total added heat, parameters such as the volume of the fresh-keeping drawer are also considered, and the environmental heating value is smaller as the volume is larger. Thus, in one embodiment, the ambient temperature increase value is determined based on 50% or 60% of the total added heat.

In an embodiment, the fresh-keeping drawer further includes a temperature sensor, and the environmental temperature rise value in step S310 may further be obtained by: detecting and obtaining initial environmental temperature and current environmental temperature through a temperature sensor; and calculating a temperature difference value between the current ambient temperature and the initial ambient temperature, and obtaining an ambient temperature rise value according to the temperature difference value. Specifically, the initial ambient temperature refers to the ambient temperature before or just after the lighting assembly is started, the current ambient temperature is the real-time ambient temperature after the lighting assembly is started, and the ambient temperature rise value is determined according to the difference between the initial ambient temperature and the current ambient temperature.

As shown in fig. 6, fig. 6 is a flowchart of a control method of a refrigerator according to another embodiment of the present invention. The control method of the refrigerator according to the embodiment of the invention includes, but is not limited to, step S510 and step S530.

Step S510, when the fresh-keeping drawer is in a ripening mode and a closing state, acquiring the initial environmental temperature of the fresh-keeping drawer;

step S520, if the initial environmental temperature is less than the preset first ripening temperature threshold, turning on the illumination assembly;

step S530, obtaining the current environmental temperature of the fresh-keeping drawer, and adjusting the illumination intensity of the illumination assembly according to the current environmental temperature and a preset second ripening temperature threshold; wherein the second ripening temperature threshold is greater than the first ripening temperature threshold.

Specifically, when the fresh-keeping drawer is in the ripening mode and the closing state, the fresh-keeping drawer is in the ripening working state, and the illumination assembly is required to be started for illumination. Taking the example that the tropical fruits are placed in the fresh-keeping drawer, the photosynthesis can be promoted and the nutrition components can be improved by irradiating the tropical fruits. And the continuous irradiation of the illumination component provides heat, so that the ambient temperature in the fresh-keeping drawer is between the first ripening temperature threshold value and the second ripening temperature threshold value, and the fresh-keeping and ripening of the tropical fruits can be realized. In addition, the illumination intensity is adjusted according to the current ambient temperature and the second ripening temperature threshold value, so that the influence on the preservation effect of tropical fruits due to the fact that the ambient temperature in the preservation drawer is too high is avoided. It is understood that the temperature requirements for the tropical fruit storage and post ripening process are high and the existing refrigeration environment cannot be met. The embodiment of the invention can meet the requirements of storing and ripening tropical fruits: the temperature rise and temperature sensor generated by the red and blue light emitted by the illumination component is used for controlling the ambient temperature of the fresh-keeping drawer to be between a first ripening temperature threshold (9 ℃) and a second ripening temperature threshold (14 ℃) for storing tropical fruits, so that the storage period can be prolonged, the fresh-keeping effect can be ensured, normal after ripening can be ensured, and the taste can be improved.

As shown in fig. 7, the illumination assembly has a first illumination intensity and a second illumination intensity, the first illumination intensity being greater than the second illumination intensity; step S530 includes, but is not limited to, steps S610 to S620.

Step S610, if the current ambient temperature is less than the preset second ripening temperature threshold, controlling the illumination assembly to operate at least with the first illumination intensity;

step S620, if the current ambient temperature is greater than a preset second ripening temperature threshold, controlling the illumination assembly to operate at a second illumination intensity, and after the illumination assembly operates for a preset illumination time period, adjusting the illumination intensity of the illumination assembly to be less than the preset second illumination intensity threshold, and at least maintaining the preset second stay time period; the second illumination intensity threshold is less than the second illumination intensity.

In particular, in the ripening mode, the ambient temperature in the fresh-keeping drawer is preferably between the first ripening temperature threshold and the second ripening temperature threshold. Thus, if the current ambient temperature is less than the second ripening temperature threshold, the illumination assembly may be controlled to continue to provide illumination at the first illumination intensity, at which time the ambient temperature in the fresh food drawer may be raised or at least maintained. If the current ambient temperature is greater than the second ripening temperature threshold, the illumination assembly is controlled to provide illumination with a second illumination intensity, and the ambient temperature in the fresh-keeping drawer is gradually reduced due to the fresh-keeping drawer being positioned in the cold-storage compartment, and after a preset illumination period, the illumination intensity of the illumination assembly is further reduced, for example, the illumination intensity is reduced to zero by closing the illumination assembly, that is, illumination is not provided any more, and a second residence period is maintained. And after the second stay time is over, the initial environment temperature of the fresh-keeping drawer is obtained again.

It should be noted that, in step S620, if the current ambient temperature is greater than the second ripening temperature threshold, the illumination assembly may be directly turned off to provide no illumination, and thus the ambient temperature in the fresh-keeping drawer is more convenient to control. However, considering that the fresh-keeping drawer is positioned in the refrigerating chamber, if the illumination intensity is directly reduced to zero, the illumination is not provided any more, and the ripening effect of the tropical fruits can be affected. Therefore, in the embodiment of the invention, even if the current ambient temperature is greater than the second ripening temperature threshold value, the illumination assembly is operated at the second illumination intensity, and after the preset illumination time, the illumination intensity of the illumination assembly is reduced to be smaller than the second illumination intensity threshold value, so that the ambient temperature in the fresh-keeping drawer is prevented from being too high, and the ripening effect and the fresh-keeping effect in the ripening mode are maintained.

The control process of the refrigerator is controlled through the steps, and in the freshness increasing mode, the growth of fruits and vegetables is stimulated through alternate irradiation of different color temperatures, so that the nutritional ingredients of the fruits and vegetables are improved. In addition, the temperature rise in the fresh-keeping drawer can be controlled by adjusting the illumination intensity through the continuous operation time of illumination, so that the balance of the fruit and vegetable cultivation and fresh-keeping quality is ensured. In the ripening mode, the temperature rise and the temperature sensor generated by the light emitting of the illumination component are utilized to control the ambient temperature of the fresh-keeping drawer to be between the first ripening temperature threshold value and the second ripening temperature threshold value, so that the fresh-keeping effect can be ensured by prolonging the storage period and the normal after ripening and the taste can be improved.

The control method of the present invention is described below by way of four practical examples.

In an example, when the refrigerator is turned on and referring to fig. 8, the control method of the refrigerator in the example includes:

when the fresh-keeping drawer is in a fresh-increasing mode and a closed state, the illumination assembly is started, and the continuous operation time of the illumination assembly is recorded; the illumination component alternately irradiates a first color temperature (red light) and a second color temperature (blue light) in a continuous operation duration;

adjusting the illumination intensity of the illumination assembly according to the continuous operation time length and the preset operation condition; wherein the operating condition is an operating duration threshold (10 minutes);

if the continuous operation time period is greater than the operation time period threshold value (10 minutes), the illumination intensity of the illumination assembly is adjusted to be smaller than a preset first illumination intensity threshold value, and at least the preset first stay time period (50 minutes) is maintained.
