In addition to the above. The virtual projection module 130 can also be pushed back manually or pushed into the accommodating cavity 114 by the side of the first door 121 of the refrigerator 100. In practical applications, the first rack 146 and the second rack 147 may further have a stop (not shown in the drawings) at two ends to control the position of the virtual projection module 130 in the accommodating chamber 114. Alternatively, the position of the virtual projection module 130 in the accommodating chamber 114 can be controlled by controlling the number of steps of the motor.
The above embodiment describes a manner in which the virtual projection module 130 directly projects the virtual control panel on the top of the second door 122. In an alternative embodiment of the present invention, as can be seen from fig. 4, a shelf 170 and a projection plate 180 may be further disposed in the first compartment 112, and the projection plate 180 may be movably connected to the shelf 170. The color of the projection plate 180 can be set at will to meet different user requirements, and the length and width can be adjusted and changed according to the projection of the virtual projection module 130, which is not limited in the present invention.
Further, as shown in fig. 5, the bottom of the shelf 170 may be provided with an accommodating portion 171, the projection plate 180 may be telescopically disposed in the accommodating portion 171, and the accommodating portion 171 may be a sliding groove or a sliding rail at the bottom of the shelf 170, so that the projection plate may telescopically slide in the accommodating portion 171. The virtual projection module 130 is further configured to project a virtual control panel to the projection plate 180. In the embodiment, the movable projection plate 180 is arranged at the bottom of the shelf 170 in the first compartment 112, so that when projection is needed, the projection plate 180 can be directly pulled out from the accommodating part 171 at the bottom of the shelf 170, and when projection is not needed, the projection plate 180 is pushed back to the accommodating part 171, which is not only convenient for use, but also does not occupy the space of the storage compartment 111.
In this embodiment, the refrigerator 100 may further include a projection plate position sensing device (not shown in the drawings) configured to sense position information of the projection plate 180 in the receiving portion 171 and transmit a position signal to the virtual projection module 130 based on the position information; wherein the position signal includes: a first position signal indicating that the projection plate 180 extends out of the receiving portion 171 to a predetermined position; and a second position signal in which the projection plate 180 is retracted into the housing portion 171. The projection plate position sensing device may be disposed in the receiving portion 171 and is in communication connection with the virtual projection module 130 and the driving device 160. It may include a plurality of sensors for sensing the position of the projection plate, such as infrared sensors or force sensitive elements.
The preset position is preferably the bottom of the first compartment 112, and the position-giving area of the first compartment 112, which is provided for the storage box of the first door 121, is located in the projection area of the bottom of the first compartment 112.
In practical applications, since the first door 121 of the refrigerator may be provided with a storage box for storing articles, the size of the storage plate 170 arranged in the first compartment 112 may be smaller than the internal size of the first compartment 112, and a position-giving area arranged in the storage box of the first door 121 is arranged in the first compartment 112, so that the storage box of the door is arranged in the position-giving area of the first compartment 112 after the door of the refrigerator is closed and cannot touch the storage plate 170 in the first compartment 112. In the embodiment, the accommodating cavity 114 is disposed at the middle position of the top of the first chamber 112, so that the virtual projection module 130 is also disposed at the middle position of the top of the first chamber 112. In addition, after the projection plate 180 is pulled out from the accommodating portion 171, the projection plate can be located in a position-giving area of the first compartment 112, which is set for the door storage box, in the projection area at the bottom of the first compartment 112, so that the virtual projection module 130 can completely project the virtual control panel at the bottom of the first compartment 112, and meanwhile, the operation of a user in a designated area can be effectively detected, and the shielding influence of the shelf plate 170 in the first compartment 112 on the projection process of the virtual control panel or the operation process of the user can be effectively reduced or even avoided.
For example, sensors of force sensors may be disposed at the front end and the rear end of the receiving portion 171, and when the projection plate 180 is pulled out from the receiving portion 171 and touches the sensors of the force sensors at the front end of the receiving portion 171, the sensors may automatically send a first position signal to the virtual projection module 130 when detecting that the projection plate 180 is fixed to a predetermined position, and at this time, the virtual projection module 130 protrudes from the receiving chamber 114 and starts projection. When the projection plate 180 is pushed back to the receiving portion 171, the projection plate 180 touches the force sensitive element at the rear end of the receiving portion 171, the projection plate position sensing device sends a second position signal to the virtual projection module 130, and at this time, the virtual projection module 130 is closed and retracted to the receiving cavity 114. In this embodiment, when the user needs the virtual projection module 130 to perform the projection of the virtual control panel, the user only needs to pull out the projection plate 180, and at this time, the position of the projection plate 180 in the accommodating portion 171 can be automatically detected by setting the projection plate position sensing device, and the virtual projection module 130 responds to the received first position signal by sending the first position signal to the virtual projection module 130 based on the position of the projection plate 180 in the accommodating portion 171, so as to meet the requirement of the user for projection. Similarly, when the user wants to stop projecting the virtual projection module 130, the user only needs to push the projection plate 180 back to the accommodating portion 171.
As shown in fig. 6, the virtual projection module 130 may include a projection module 131 configured to project a virtual control panel onto the projection partition after receiving a first position signal sent by the projection board position sensing device; or stopping projecting the virtual control panel to the projection partition after receiving a second position signal sent by the projection plate position sensing device. In the embodiment of the present invention, by providing the projection plate position sensing device, the position of the projection plate 180 in the accommodating portion 171 of the shelf 170 can be automatically detected, and further when the projection plate 180 is pulled out from the accommodating portion 171, the virtual projection module 130 can be automatically driven to extend out of the accommodating chamber 114 and perform projection, and a user does not need to manually trigger the extension and retraction of the virtual projection module 130 in the accommodating chamber 114, so as to further improve user experience.
The projection assembly 131 may be a laser projection assembly 131 composed of RGB three-color laser emitters that emit imaging lasers and project a virtual control panel within a designated area. The virtual control panel may be an operation control panel for selecting relevant information such as an operation mode and an operation temperature of the refrigerator 100, for example, an operation parameter of the refrigerator 100, and may further be an information display panel for displaying information such as a designated image, a picture, and article storage knowledge, and the virtual control panel projected by the projection component 131 may further have a plurality of touch keys therein to set the regulation and control requirements and display requirements of different operation scenes of the refrigerator 100.
With continued reference to fig. 6, the virtual projection module 130 may further include: the sensing component 132 is configured to detect and recognize an operation of the virtual control panel on the projection panel 180 by a user, and generate an operation instruction corresponding to the operation to be provided to the main control panel of the refrigerator 100 for the main control panel to respond to the operation instruction. Alternatively, the projection component 131 may transmit an infrared signal, and the sensing component 132 may be an infrared receiving component for detecting the interruption of the infrared signal, so as to capture the related operations of the user in the designated area.
In this embodiment, the virtual projection module 130 may further include: the mounting box 133, the mounting box 133 can be provided with a transparent box cover, and the projection component 131 and the sensing component 132 are arranged in the mounting box 133 in parallel; the mounting box 133 is provided on the retractable device 140. When the virtual control panel is arranged specifically, the interval between the projection assembly 131 and the sensing assembly 132 can be controlled to be smaller than a certain distance, the projection surface of the projection assembly 131 can be overlapped with the detection surface of the sensing assembly 132 to the maximum extent, the virtual control panel falls into the overlapping area of the projection surface and the detection surface, and the operation of a user on the virtual control panel can be effectively detected through the sensing assembly 132 while the projection is realized. The virtual projection module 130 may further include a processor 134 as a control core for controlling the operating states of the projection element 131 and the sensing element 132.
According to the refrigerator 100 with the projection function provided by the embodiment of the invention, the virtual projection module 130 is telescopically arranged in the accommodating cavity 114 at the top of the first compartment 112, and the virtual control panel is projected after the first door body 121 is opened, so that the problems of space occupation of the refrigerator 100 by the virtual projection module 130, projection light shielding, condensation and device cleanness can be effectively solved. Further, when the virtual projection module 130 in this embodiment projects the virtual control panel, the virtual control panel can be directly projected vertically downward toward the plane at the top of the second door 122 after extending out of the accommodating cavity 114. In addition, when the virtual projection module is not needed to project the virtual control panel, the projection module can be retracted into the accommodating cavity 114 and hidden in the box body 110, so that the appearance is not influenced, the operation of a user is greatly facilitated, and the user experience is further improved.
In addition, the refrigerator 100 provided by the embodiment of the present invention may further include a projection plate 180 separately disposed and movably connected to the storage plate 170 in the storage compartment 111, and the projection plate 180 is detected by a projection plate position sensing device, and when a projection is required, the projection plate 180 is directly pulled out, and the projection of the virtual control panel is realized by automatically detecting that the projection plate is in a pulled-out state by the projection plate position sensing device.
