Figure 2 As shown, the projection module 2 can also be arranged at the bottom of the baton 3, and can be extended along with the baton to realize projection when the baton is controlled to adjust the atmosphere. Specifically, the baton 3 is configured to control and adjust the atmosphere of the environment where the refrigerator is located. The baton 3 is also provided with a camera configured to perform user recognition. In practical applications, such as Figure 3 As shown, after the door of the storage compartment is opened, the projection module can control the projection module 2 to project light / images into the interior of the storage compartment, so that the user can know the specific location of the food in time.

[0037] Figure 4 is a schematic diagram of a method for controlling a refrigerator provided by an embodiment of the present disclosure; Figure 4 As shown, the embodiment of the present disclosure discloses a method for controlling a refrigerator, comprising:

[0038] S41, the refrigerator obtains the food information selected by the user.

[0039] S42, the refrigerator determines a target control strategy for the projection module according to the food information.

[0040] S43, the refrigerator controls the projection module to execute the target control strategy.

[0041] In this solution, the refrigerator can obtain the food information selected by the user in a variety of ways. In one example, if the refrigerator includes a smart display, the refrigerator can obtain the food information selected by the user by obtaining the user's operation information on the smart display. In another example, if the refrigerator receives a food selection instruction sent by the user through a mobile device, the refrigerator can determine the food information in the food selection refrigeration as the food information selected by the user. Specifically, the food information includes the name of the food, the storage information of the food, and the shelf life of the food. In this way, the food information selected by the user can be accurately obtained in a variety of ways.

[0042] Furthermore, the refrigerator determines the target control strategy of the projection module according to the food information, including: matching the target storage location corresponding to the food name in the food information library; determining the target storage location as the target projection location of the projection module; and determining the target control strategy of the projection module to control the projection module to project light to the target projection location. In this way, the target control strategy of the projection module can be accurately determined in combination with the determined target projection location, so that when the projection module is controlled to execute the target control strategy, the light beam projected by the projection module is accurately irradiated to the target projection location.

[0043] The method for controlling a refrigerator provided by the embodiment of the present disclosure is adopted to obtain the food information selected by the user; thereby determining the target control strategy of the projection module according to the food information; and then controlling the projection module to execute the target control strategy. In this way, the target control strategy of the projection module can be accurately determined in combination with the food information, so that when the projection module is controlled to execute the target control strategy, the storage location of the food is determined by the projection path of the projection module, which is convenient for the user to take the food in time, effectively saving the time of taking the food, and also reducing the probability of cold air loss caused by the refrigerator door being opened for a long time, thereby meeting the user's demand for the use of the refrigerator.

[0044] Optionally, in S42, the refrigerator determines a target control strategy of the projection module according to the food information, including:

[0045] The refrigerator matches the target storage location corresponding to the ingredient name in the ingredient information library.

[0046] The refrigerator determines the target storage position as the target projection position of the projection module.

[0047] The refrigerator determines that the target control strategy of the projection module is to control the projection module to project light to the target projection position.

[0048] In this solution, the food information is the name of the food. The refrigerator can pre-store the food information library, and the refrigerator can also obtain the food information library through its associated server. It can be understood that after the user puts the food into the refrigerator, the refrigerator can obtain the storage location of the food through the positioning module, and establish a corresponding relationship between the food name and the storage location, so as to store it in the food information library. In this way, the refrigerator can match the storage location corresponding to the food name in the food information library and determine it as the target storage location. In this way, the target storage location can be accurately determined.

[0049] Furthermore, the refrigerator can determine the target storage location as the target projection location of the projection module, and the refrigerator determines the target control strategy of the projection module as controlling the projection module to project light to the target projection location. In this way, the storage location of the food can be determined by the projection path of the projection module, so that the user can take it in time.

[0050] Optionally, the refrigerator controls the projection module to project light to a target projection position, including:

[0051] The refrigerator obtains information about the freshness of ingredients.

[0052] The refrigerator determines the target lighting projection plan based on the freshness information of the ingredients.

[0053] The refrigerator controls the projection module to project light to the target projection position according to the target light projection plan.

[0054] In this solution, the refrigerator obtains the freshness information of the food, wherein the freshness information is the freshness level, and the freshness level includes the first level, the second level and the third level. The higher the freshness level, the higher the degree of deterioration of the food. Specifically, the refrigerator obtains the freshness level of the food, including: the refrigerator obtains the pH value change trend of the food; the refrigerator determines the freshness level of the food according to the pH value change trend of the food. The pH value of the food can be obtained by a pH sensor. Figure 5 As shown, the refrigerator determines the freshness level of the food according to the change trend of the pH value of the food, including: when the change trend of the pH value of the food is unchanged, the freshness level of the food is determined to be the first level; when the change trend of the pH value of the food is a downward trend, the freshness level of the food is determined to be the second level; when the change trend of the pH value of the food is an upward trend, the freshness level of the food is determined to be the third level. It should be noted that the first level indicates that the food is relatively fresh, the second level indicates that the food is beginning to rot, and the third level indicates that the food is already rotten. In this way, the freshness information of the food can be accurately judged in combination with the acquisition results of the pH value sensor.

[0055] Furthermore, the freshness information is a freshness level, and the refrigerator determines a target light projection scheme according to the freshness information of the food, including: when the freshness level is the first level, determining the target light projection scheme is to control the projection module to project green light to the target projection position; when the freshness level is the second level, determining the target light projection scheme is to control the projection module to project yellow light to the target projection position; when the freshness level is the third level, determining the target light projection scheme is to control the projection module to project red light to the target projection position. In this way, the user can timely distinguish the current freshness of the food according to the color projected by the projection module.

[0056] In another example, the refrigerator determines the target light projection scheme according to the freshness information of the food, including: when the freshness level is the first level, the target light projection scheme is determined to control the projection module to project the first aperture to the target projection position; when the freshness level is the second level, the target light projection scheme is determined to control the projection module to project the second aperture to the target projection position; when the freshness level is the third level, the target light projection scheme is determined to control the projection module to project the third aperture to the target projection position. Wherein, the area of ​​the first aperture is less than the area of ​​the second aperture and less than the area of ​​the third aperture. In this way, the user can timely distinguish the current freshness of the food according to the aperture area projected by the projection module.

[0057] Furthermore, after determining the target light projection scheme, the refrigerator can control the projection module to project light to the target projection position according to the target light projection scheme, so that the user can timely identify the current freshness of the food according to the light projection situation at the target projection position.

[0058] Optionally, after determining the target storage location, the method further includes:

[0059] The refrigerator determines the storage compartment in which the target storage location is located.

[0060] The refrigerator controls the light assembly of the refrigerator to open the storage compartment door so that the user can know the storage compartment where the food is located.

[0061] In this solution, the storage compartment includes a refrigeration compartment or a freezer compartment. The light component of the storage compartment door can be a light tube and is arranged on the outside of the storage compartment door. In this way, the refrigerator can determine the storage compartment where the target storage position is located in combination with the acquired positioning information, and control the refrigerator to open the light component of the storage compartment door. With this solution, when the user approaches the refrigerator, the storage compartment of the food can be determined by the light display on the outside of the storage compartment door, which helps the user to open the door of the storage compartment.

[0062] Optionally, in S42, the refrigerator determines a target control strategy of the projection module according to the food information, including:

[0063] The refrigerator generates a target prompt screen of food storage information according to the user's display preferences.

[0064] The refrigerator determines that the target control strategy of the projection module is to control the projection module to project the target prompt image to the target projection position.

[0065] In this solution, the refrigerator can identify the identity of the user through an image sensor, and match the display preferences corresponding to the user's identity in the server as the user's display preferences. Here, the display preferences include pictures, text, etc. In this way, the refrigerator can generate a target prompt screen for the food storage information according to the user's display preferences. Among them, the food storage information includes the food storage date, the food storage time, etc. In this way, a target prompt screen that meets the user's display preferences can be obtained. Further, the refrigerator can determine that the target control strategy of the projection module is to control the projection module to project the target prompt screen to the target projection position. In this way, it is convenient for users to view the food storage information more intuitively at the target projection position.

[0066] Optionally, before obtaining the food information selected by the user, the method further includes:

[0067] The refrigerator obtains the user's movement trajectory.

[0068] When the movement trajectory of the user indicates that the user is close to the refrigerator, the refrigerator controls the projection module to perform tracking and projection according to the movement trajectory of the user.

[0069] In this solution, the refrigerator may be associated with a radar sensor. The refrigerator may obtain the user's location information at different times through the radar sensor to determine the user's movement trajectory. Furthermore, when the user's movement trajectory indicates that the user is close to the refrigerator, the refrigerator controls the projection module to track and project according to the user's movement trajectory. For example, the refrigerator may control the projection module to project onto the ground at the user's location along the user's movement trajectory. With this solution, tracking and projection can be performed in combination with the user's movement trajectory, so that the user can obtain the projection information of the projection module at any location, thereby improving the flexibility of controlling the projection module.

[0070] In an optimized solution, the refrigerator obtains the distance information between the user and the refrigerator; when the distance information is greater than a first distance, the control of the projection module to perform tracking projection is stopped. Here, the first distance is 2 meters. In this way, the precise control of the projection module is achieved, and the user's energy-saving control requirements for the projection module are met.

[0071] Optionally, the refrigerator controls the projection module to perform tracking projection according to the movement trajectory of the user, including:

[0072] The refrigerator recognizes the user's identity information.

[0073] The refrigerator determines the projection image of the projection module according to the user's identity information.

[0074] The refrigerator controls the projection module to track and project the projection image according to the user's movement trajectory.

[0075] In this solution, the refrigerator is associated with an image sensor. The refrigerator can identify the user through the image information collected by the image sensor to obtain the user's identity information. Here, the user's identity information includes father, mother, grandfather, grandmother, child, etc. It can be understood that the personalized projection images liked by different family users are not the same, and the refrigerator can pre-store the association relationship between the personalized projection image and the user's identity information. In this way, the refrigerator can match the projection image of the projection module associated with the user's identity information in combination with the pre-stored association relationship. In this way, the projection image of the projection module can be accurately determined. Furthermore, the refrigerator can control the projection module to track and project the projection image according to the user's movement trajectory. In this way, after identifying the user, the corresponding personalized projection image can be displayed according to the user's preferences, effectively enhancing the interactivity between the refrigerator and the user and creating a good refrigerator usage atmosphere.

[0076] In an optimized solution, if the refrigerator stores the birth dates of different users, the projection module is controlled to project a birthday blessing picture on the birth date. Here, the birthday blessing picture can be projected to the target projection area intended by the user. In this way, the interaction between the refrigerator and the user is effectively enhanced, creating a good refrigerator usage atmosphere.

[0077] In an optimized solution, if the refrigerator stores different holiday dates, the projection module is controlled to project holiday greeting images on different holiday dates. Here, the holiday greeting images can be projected to the target projection area intended by the user. In this way, the interaction between the refrigerator and the user is effectively enhanced, and a good refrigerator usage atmosphere can be created during holidays.
