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 112 at the top of the storage compartment 111, and extends out of the accommodating cavity 112 for projection when projection is required, 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. When the virtual projection module 130 is not needed to project a virtual control panel, the virtual control panel can be retracted into the accommodating cavity 112 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. The accommodating cavity 112 in this embodiment is located at the middle position of the top of the storage compartment 111, and the color of the projection plate 120 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.
In this embodiment, the refrigerator 100 may be separately provided with the projection plate 120, and the projection plate 120 may be movably connected to the refrigerating drawer 114. When the virtual projection module 130 is required to perform projection, the projection plate 120 is only required to be fixed to a predetermined position. The preset position is preferably the bottom of the refrigerating chamber 113, and the escape area of the refrigerating chamber 113, which is provided for the door storage box, is located in the projection area of the bottom of the refrigerating chamber 113.
In practical application, because the door body of the refrigerator is provided with the storage box for storing articles, the size of the storage plate arranged in the cold storage chamber 113 is smaller than the internal size of the cold storage chamber 113, and the cold storage chamber 113 is provided with a yielding area arranged on the door body storage box, so that the door body storage box is arranged in the yielding area of the cold storage chamber 113 after the door body of the refrigerator is closed and cannot touch the storage plate in the cold storage chamber 113. In the embodiment, the accommodating cavity 112 is disposed at the middle position of the top of the refrigerating compartment 113, so that the virtual projection module 130 is also disposed at the middle position of the top of the refrigerating compartment 113. In addition, the projection plate 120 is arranged in a projection area which is located in the refrigerating chamber 113 and is arranged at the bottom of the refrigerating chamber 113 as a position-giving area of the door storage box, so that the virtual projection module 130 can completely project the virtual control panel at the bottom of the refrigerating chamber 113, and meanwhile, the operation of a user in a specified area can be effectively detected, and the shielding influence of the projection process of the virtual control panel or the process of detecting the operation of the user by the storage plate in the refrigerating chamber 113 is effectively reduced or even avoided.
In an alternative embodiment of the present invention, the projection plate 120 may be pivotally connected to the lower edge of the front plate 115 of the refrigeration drawer 114. As can be seen in conjunction with fig. 1-3. When projection is needed, the projection plate 120 can be directly turned over to be turned over from the state of being tightly attached to the front plate 115 of the refrigeration drawer 114 to the state of being perpendicular to the front plate 115, and when projection is not needed, the projection plate and the refrigeration drawer 114 are attached, so that the whole operation is simple, and the user experience is high. As shown in fig. 3, a rotating shaft 122 may be provided at one end of the projection plate 120, and the front plate 115 of the cold storage drawer 114 may be connected to the rotating shaft 122 in a reversible manner. Fig. 1 and 2 are schematic diagrams illustrating the projection panel 120 attached to the front panel 115 of the refrigeration drawer 114 and turned upside down, respectively.
In another alternative embodiment of the present invention, as can be seen from fig. 4-6, the bottom of the refrigeration drawer 114 has a receiving portion 116, and the projection plate 120 is telescopically disposed in the receiving portion 116, and the receiving portion 116 may be a sliding slot or a sliding rail at the bottom of the refrigeration drawer 114, so that the projection plate can telescopically slide in the receiving portion 116. When projection is needed, the projection plate 120 can extend out from the receiving portion 116 at the bottom of the refrigeration drawer 114, and when projection is not needed, the projection plate 120 can be retracted into the receiving portion 116, so that the use is convenient, and the space of the storage compartment is not occupied, and fig. 4 and 5 respectively show schematic diagrams of the projection plate 120 retracting into the receiving portion 116 and extending out of the receiving portion 116. In order to facilitate the user to pull the projection plate 120 out of the receiving portion 116, a member such as a fastener may be provided on the projection plate 120.
Optionally, as can be seen from fig. 1 and 4, in the embodiment of the present invention, a projection plate position sensing device 150 may be disposed in the refrigerator 100 to detect the position of the projection plate 120. The projection plate position sensing device 150 is communicatively connected to the virtual projection module 130, and the projection plate position sensing device 150 is configured to detect the position information of the projection plate 120 and send 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 panel 120 is at a predetermined position; and a second position signal indicating that the projection panel 120 is attached to the front panel 115 of the refrigeration drawer 114.
The virtual projection module 130 is further configured to project a virtual control panel to the projection partition after receiving the first position signal sent by the projection plate position sensing device 150; or when receiving the second position signal sent by the projection board position sensing device 150, stopping projecting the virtual control panel to the projection partition.
In the embodiment of the present invention, the projection plate position sensing device 150 may be disposed in the refrigeration compartment 113, and by disposing the projection plate position sensing device 150, the automatic detection of the position of the projection plate may be implemented, so as to implement the automatic control of the virtual projection module 130. When a user needs to project a virtual control panel to the virtual projection module 130, the projection plate 120 movably connected to the refrigeration drawer 114 can be directly fixed to a preset position, the projection plate position sensing device 150 can immediately send a first position signal to the virtual projection module 130 after detecting the first position signal, and the virtual projection module 130 can quickly respond to the projection of the virtual control panel after receiving the first position signal. When the virtual projection module 130 is not needed to project the virtual control panel, the projection plate 120 is turned over and attached to the front plate 115 of the refrigeration drawer 114. Based on the scheme provided by this embodiment, the user can realize the control of the projection state of the virtual projection module 130 by the turning control or the stretching control of the projection plate 120, the whole control process is simple and effective, and the user experience is high.
In an alternative embodiment of the present invention, the projection plate position sensing device 150 may include a Hall sensor 151, as shown in FIGS. 4-5. In addition, the projection plate 120 may further include a first magnetic element 121, and the first magnetic element 121 may be a magnetic strip. The hall sensor 151 is disposed at the bottom of the refrigeration compartment 113, is in communication with the virtual projection module 130, and is configured to send a first position signal to the virtual projection module 130 after detecting that the projection board 120 is fixed to a preset position (e.g., when the lower edge of the front board 115 of the refrigeration drawer 114 is turned to the bottom of the refrigeration compartment 113 or extends out from the bottom of the refrigeration drawer 114) based on the first magnetic element 121. The virtual projection module 130 is further configured to project a virtual control panel to the projection plate 120 after receiving the first position signal sent by the hall sensor 151. In this embodiment, the hall sensor 151 is disposed at the bottom of the refrigerating compartment 113, and a relief area of the refrigerating compartment 113 for the door storage box is located in a projection area at the bottom of the refrigerating compartment 113.
The hall sensor 151 is a magnetic field sensor made according to the hall effect, and can detect a magnetic field and its variation. In this embodiment, the first magnetic element 121 is mounted on the projection plate 120, the hall sensor 151 is mounted at the bottom of the refrigeration compartment 113, when the projection plate 120 is turned over to the bottom of the refrigeration compartment 113 along the refrigeration drawer 114 or extends out from the bottom of the refrigeration drawer 114, the distance between the hall sensor 151 and the first magnetic element 121 is continuously reduced, and when the hall sensor 151 at the bottom of the refrigeration compartment 113 can sense the magnetic force of the first magnetic element 121 on the projection plate 120, the hall sensor 151 triggers to operate, transmits a start signal to the virtual projection module 130, and the virtual projection module 130 starts to operate and projects a virtual control panel to the projection plate 120 in response to the start signal. Similarly, when the first magnetic element 121 is far enough away from the hall sensor 151, the hall sensor 151 does not sense magnetism and is not triggered. Optionally, the hall sensor 151 is disposed corresponding to the first magnetic element 121, and when the projection panel 120 is turned to the bottom of the refrigerating compartment 113 along the refrigerating drawer 114 or extends out from the bottom of the refrigerating drawer 114, the hall sensor 151 overlaps the first magnetic element 121.
Optionally, the projection plate position sensing device 150 may also be an angle detection device, configured to detect an angle between the projection plate 120 and the front plate 115 of the refrigeration drawer 114, when a preset angle, such as 90 °, is reached between the projection plate 120 and the front plate 115 of the refrigeration drawer 114, or other angles capable of achieving projection, at this time, a first position signal may be sent to the virtual projection module 130 to control the virtual projection module 130 to start projecting the virtual control panel; when detecting that the angle between the projection plate 120 and the front plate 115 of the refrigeration drawer 114 is zero or smaller than the preset angle by a certain range of values, a second position signal may be sent to the virtual projection module 130 to control the virtual projection module 130 to stop projecting the virtual control panel.
In the above embodiment, the projection plate 120 may also be telescopically disposed in the receiving portion 116 at the bottom of the refrigeration drawer 114, and therefore, the projection plate position sensing device 150 may further include a force sensor, for example, force sensors may be respectively disposed at the front end and the rear end of the receiving portion 116, when the projection plate 120 is pulled out from the receiving portion 116, the projection plate touches the force sensor at the front end of the receiving portion 116, and when the sensor detects that the projection plate 120 is fixed to a specific position, a first position signal may be automatically sent to the virtual projection module 130, and at this time, the virtual projection module 130 extends out of the receiving chamber 112 and starts projection. When the projection plate 120 is pushed back to the receiving portion 116, the projection plate 120 touches the force sensor at the rear end of the receiving portion 116, the projection plate position sensing device 150 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 112. In this embodiment, when the user needs the virtual projection module 130 to perform projection of the virtual control panel, the user only needs to pull out the projection plate 120, and at this time, the position of the projection plate 120 in the accommodating portion 116 can be automatically detected by setting the projection plate position sensing device 150, 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 120 in the accommodating portion 116, so as to meet the requirement of projection of the user. Similarly, when the user wants to stop projecting the virtual projection module 130, the user only needs to push the projection plate 120 back to the accommodating portion 116.
In practical applications, the projection board position sensing device 150 may also detect the position of the projection board 120 through other methods such as a camera and an infrared sensor, which are not described herein again.
As described above, when the virtual projection module 130 does not project, it can be attached to the front panel 115 of the refrigeration drawer 114. Alternatively, the projection plate 120 and the front plate 115 of the refrigeration drawer 114 may be magnetically attached. In the above embodiment, the projection plate 120 may be provided with a first magnetic element 121, and correspondingly, the surface of the front plate 115 of the refrigeration drawer 114 may be provided with a second magnetic element (not shown in the figures), and the projection plate 120 and the front plate 115 of the refrigeration drawer 114 are magnetically fixed by the first magnetic element 121 and the second magnetic element. Of course, the projection plate 120 and the front plate 115 of the refrigeration drawer 114 may be fixed by other means such as a snap fit.
Optionally, a retractable device 140 may be disposed in the accommodating cavity 112, and the retractable device 140 is used to drive the virtual projection module 130 to extend out of the accommodating cavity 112 and retract into the accommodating cavity 112. A switch button (e.g., a position of a side or a top of the box 110) may be disposed on a surface of the box 110, and the switch device is connected to the retractable device 140 and configured to control the retractable device 140 to extend or retract into the accommodating cavity 112, so that a user can control the virtual projection module 130 to project or stop projecting the virtual control panel as required.
The retractable device 140 is communicatively connected to the virtual projection module 130, and the retractable device 140 is configured to acquire an extending signal transmitted by the virtual projection module 130 when receiving the first position signal sent by the projection board position sensing device 150, so as to extend from the accommodating cavity 112 in response to the extending signal.
