The refrigerator related to the invention also has a database for storing data such as static patterns, static characters, dynamic videos and the like, and the main control module calls required data from the database and controls the projection emitter 132 to perform projection display through the projection control panel.
More specifically, the projection emitter 132 may be an LED lamp and a corresponding optical path processing component, or may be a laser emitter, and the specific structure may refer to the existing design and will not be further described herein. In a specific application process, the projection emitter 132 can adjust the illumination brightness and color variation. The sensor assembly may include an infrared transmitter and receiver based on which the current position of the user may be detected.
In the specific implementation process of the present invention, the main control module is used for associating the projection module 13, the human sensing module 14 and the database. It can be understood that, in the specific use process of the refrigerator, the refrigeration system for refrigerating the refrigerator can also be associated to the main control module, so that the refrigeration operation process of the refrigerator can be controlled by the main control module.
Further, in some embodiments of the present invention, the refrigerator has a body projection surface 15 disposed on a front side surface of the cabinet 11, the triggering unit has a first triggering state that triggers the projection module 13 to project toward a front ground surface of the cabinet 11 when the user is within a first set distance range, and a second triggering state that triggers the projection module to project toward the body projection surface 15 when the user is within a second set distance range, a distance value within the first set distance range is greater than a distance value within the second set distance range.
As shown in fig. 3, the projection module 13 has two projection directions, i.e., a first direction directly projected toward the ground and a second direction directly projected toward the body projection surface 15. When the user is far away from the cabinet 11, if the human sensing module 14 senses that the user is within the range of the S1 area shown in fig. 1, the projection module 13 projects the image directly towards the ground; when the user is far away from the cabinet 11, if the human sensing module 14 senses that the user is within the range of the S2 region shown in fig. 1, the projection module 13 directly projects toward the projection surface 15 of the main body.

In other embodiments of the present invention, the projection emitter 132 may be rotatably connected to a fixed support, and rotated to achieve different directional transmission.
Preferably, referring to fig. 1, the first set distance range referred to in the present invention is 1 to 2m, and the second set distance range is not more than 1m.
Further, in some embodiments of the present invention, the projection content of the projection transmitter 132 when the trigger unit is in the first trigger state is different from the projection content when the trigger unit is in the second trigger state. In other words, the projection transmitter 132 projects different content in the direction of the ground surface than in the direction of the projection surface 15 of the main body.
In particular, there is often some difference in the need to obtain information when the user is in different locations. In this regard, in the implementation of the present invention, when the user is in the relatively distant S1 area, the content projected to the ground direction by the projector 132 is usually advertisement information, such as static information or dynamic information like LOGO, image of the product, etc. When the user is in the relatively close S2 area, the content projected by the projection emitter 132 to the projection plane 15 direction of the main body is usually detailed commodity information, such as commodity type, price, date, promotion commodity recommendation, unlocking two-dimensional code, settlement two-dimensional code, etc., and refrigerator operation fault codes, such as sensor fault, fan fault, high temperature alarm, etc. Based on the body projection plane 15, a user can directly select to purchase commodities through displayed information, unlock the displayed two-dimensional code to take the commodities, and settle accounts through the displayed settlement two-dimensional code; the refrigerator manager can also confirm the fault problem through the displayed alarm code.
As a preferred embodiment of the present invention, the fixing bracket 131 according to the present invention includes an electric turret to which the projection transmitter 132 is rotatably connected, the electric turret including a first rotating unit (not shown) to which the projection transmitter 132 is vertically rotated, and being configured to: when the sensor assembly senses that the user is located in the first set distance range and far away from or close to the cabinet body, the first rotating portion rotates to adjust the projection direction of the projection emitter 132 so that the projection content is located on one side, close to the cabinet body, of the user. The design can ensure that the projection content is completely positioned in front of the user, so that the user can watch the complete projection content conveniently.
Further, in another embodiment of the present invention, the electric rotary head further includes a second rotating portion for rotating the projection emitter 132 left and right, and is configured to: when the sensor assembly senses that the user is located within the first set distance range and moves left and right, the second rotating portion rotates to adjust the projection direction of the projection emitter 132 so that the projection angle is matched with the current position of the user. It is easy to understand that the projection angle is adaptive to the current position of the user, which means that the angle displayed by the projection content is consistent with the angle of the habit of the user to watch the plane information.
In some embodiments of the present invention, the triggering unit further has a third triggering state for switching the projection direction from the direction toward the front ground of the cabinet 11 to the direction toward the projection plane 15 of the body when the user is within the first set distance range and the staying time exceeds the preset time. The arrangement mode can be better combined with the user behavior, specifically, when the user stays in the front of the cabinet 11 for a long time within a certain distance, which indicates that the user has an intention to purchase the corresponding commodity to a large extent, the projection direction of the projection emitter 132 is switched to the body projection plane 15, so that more detailed commodity information can be provided for the user, and the user can conveniently perform the next action.
In specific implementation, the preset time involved in this embodiment may be 10 to 100s; wherein the preset time is preferably 30-60s.
