Fig. 1 is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention, and referring to fig. 1, the refrigerator 100 provided in this embodiment may include: a case 110 defining at least one storage compartment 111; virtual projection device 120, virtual projection device 120 may be configured to project a virtual control panel. Optionally, in this embodiment, the refrigerator 100 may further include an illumination device 130. In this embodiment, each storage compartment 111 can be used as an independent compartment for storing articles, such as a refrigeration zone, a temperature-changing zone, a quick-freezing zone, and the like. Alternatively, the storage compartment 111 may include a refrigerating compartment 112, and the refrigerating compartment 112 may be divided into a plurality of independent storage areas, such as independent temperature-changing areas, dry and wet separate storage boxes, and the like.
The lighting device 130 includes a first light emitting unit (not shown in the drawings) and a second light emitting unit (not shown in the drawings). The first light-emitting unit can be disposed in any storage chamber 111 as an operation prompt lamp to provide a light-on prompt when a user operates the storage chamber 111. The second light emitting unit is disposed on an inner wall of the box body 110 and is mainly used for providing lighting service. In this embodiment, the first light-emitting unit and the second light-emitting unit both preferentially adopt RGB _ LED lamps, and light of a desired color is obtained by imaging with a common intersection of three primary colors, wherein the first light-emitting unit is disposed in the storage compartment 111 and mainly plays a role of prompting, and thus, a white LED lamp may be adopted. The number of the first light emitting unit and the second light emitting unit can be set according to the size of the refrigerator, the setting environment or the user attribute, and the invention is not limited
As shown in fig. 2, the virtual projection apparatus 120 may include: a projection assembly 121 configured to project a virtual control panel within a designated area of the storage compartment 111; a sensing component 122 configured to detect user operation in a designated area; and a processor 123 configured to recognize an operation of the virtual control panel by the user according to the detection result of the sensing assembly 122, 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.
According to the refrigerator 100 provided by the embodiment, the projection assembly 121 is used for projecting the virtual control panel in the storage compartment 111 of the refrigerator 100, so that the internal function display and the control adjustment of the refrigerator 100 are facilitated, especially, under the condition that a refrigerator door body is opened, the virtual control panel can be projected in a specified area through the virtual projection device 120 arranged in the storage compartment 111 of the refrigerator body 110, so that different operations of a user of the refrigerator 100 are facilitated, the use requirement of the user is met, and the user experience is improved. The processor 123 in this embodiment is mainly used as a core data processing component of the virtual projection apparatus 120, and is in communication connection with the projection component 121 and the sensing component 122 to implement controlling the projection component 121 to project and controlling the sensing component 122 to detect, and determine whether the virtual control panel is operated by a user according to data detected by the sensing component 122, so as to send a corresponding operation instruction to the main control panel of the refrigerator 100. The virtual control panel projected by the projection component 121 may be an operation control panel (e.g., a virtual touch panel) for selecting relevant information such as an article type to be put in according to operation parameters such as an operation mode and an operation temperature inside the refrigerator by a user, and may also be an information display panel (e.g., preset image information) for presenting information such as a designated image, a picture, article storage knowledge, and the like, and the virtual control panel projected by the projection component 121 may further have a plurality of touch keys to set the regulation and control requirements and display requirements of different operation scenes of the refrigerator.
In an embodiment of the present invention, as shown in fig. 1, the storage compartment 111 may include a refrigerating compartment 112; the projection assembly 121 and the sensing assembly 122 are disposed at the top of the refrigerating compartment 112. The second light emitting unit may specifically include a sidewall light emitting unit and a rear wall light emitting unit, the sidewall light emitting unit may be disposed on a sidewall of the refrigerating compartment 112, and the rear wall light emitting unit is disposed on a rear wall of the refrigerating compartment.
As can be seen from fig. 1 and fig. 2, the virtual projection apparatus 120 may further include a mounting box 124, and the projection module 121, the sensing module 122, and the processor 123 of the virtual projection apparatus 120 may be disposed in the mounting box 124. The mounting box 124 may be provided with a transparent box cover, and the projection component 121 and the sensing component 122 are arranged in the mounting box 124 in parallel and located on one side of the mounting box 124 close to the refrigerator door. The mounting box 124 may be disposed at a middle position of the top of the refrigerating compartment 112 and at a distance within a predetermined distance range from the front end of the box body 110. In this embodiment, the components in the virtual projection apparatus 120 can be integrated together by the mounting box 124, and the positions of the components are reasonably arranged, so that the space occupied by the virtual projection apparatus 120 inside the refrigerator 100 can be greatly reduced. In this embodiment, the projection module 121 is disposed on the top of the refrigerating compartment 112, so that the projection module 121 projects a virtual control panel vertically. The distance between the mounting box 124 and the front end of the box 110 is within a preset distance range, which can be further adjusted according to the size of the refrigerator 100, so that the projection distance is shortest, the projection angle is best, and the shielding effect is small.
For example, assuming that the length of the refrigerating compartment 112 of the refrigerator 100 is L (cm) and the width is W (cm), the center of the mounting box 124 is located at L/2, which provides a better projection position, and the projection shape is not deformed, considering the influence of the spacer rack objects on the projection, the distance M (cm) from the front end of the box 110 (specifically, the outer edge of the top of the refrigerator 100) is considered, and M < W/2, which is to prevent the bottle seat of the refrigerating compartment from colliding.
In an alternative embodiment of the present invention, as can be seen from fig. 1 and 3, the virtual projection device 120 may project a virtual control panel to a designated area of the bottom of the refrigerating compartment 112. The projection of the virtual control panel to the refrigerating compartment 112 can be realized by the projection module 121. Optionally, the designated area of the projection module 121 projecting the virtual control panel to the bottom of the refrigerating compartment 112 is preferentially located in the projection area of the door storage box of the refrigerating compartment 112 in the bottom of the refrigerating compartment 112, so that the projection distance of the virtual projection device 120 is shortest, the projection angle is best, and the shielding effect is small. The virtual control panel may be an operation control panel (e.g., a virtual touch panel) for selecting relevant information such as article types and the like from operation parameters such as an operation mode and an operation temperature in the refrigerator by a user, and may also be an information display panel (e.g., preset image information) for presenting information such as designated images, pictures, article storage knowledge and the like, and may be specifically set according to different requirements, which is not limited in the present invention.
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 refrigerating chamber 112 is smaller than the internal size of the refrigerating chamber 112, and the refrigerating chamber 112 is provided with the yielding area arranged on the door body storage box, so that the door body storage box is arranged in the yielding area of the refrigerating chamber 112 after the door body of the refrigerator is closed and cannot touch the storage plate in the refrigerating chamber 112. In the solution provided by this embodiment, the virtual projection device 120 is disposed at the middle position of the top of the refrigerating compartment 112, and the designated area of the projection component 121 projecting the virtual control panel to the storage compartment 111 is preferentially located in the projection area of the refrigerating compartment 112 at the bottom of the refrigerating compartment 112, which is the escape area of the door storage box for the refrigerating compartment 112, so that not only the projection component 121 can completely project the virtual control panel at the bottom of the refrigerating compartment 112, but also the sensing component 122 can effectively detect the operation of a user in the designated area, thereby effectively reducing or even avoiding the shielding effect of the shelf in the refrigerating compartment 112 on the projection process of the virtual control panel or the process of detecting the operation of the user.
Optionally, the projection assembly 121 and the sensing assembly 122 form a projection surface and a detection surface in a designated area, and the projection surface and the detection surface are at least partially overlapped; the projection assembly 121 is further configured to project a virtual control panel in an overlapping area of the projection plane and the detection plane.
As shown in fig. 3, it is assumed that the designated area is area 1, the projection surface of the projection unit 121 is area 2, and the detection surface of the sensing unit 122 is area 3. Wherein both region 2 and region 3 belong to a part within region 1, and region 2 and region 3 have an overlapping region, region 4. The virtual control panel projected by the projection component 121 is located in the area 4. When the designated area is the designated area at the bottom of the refrigerating compartment 112, it is assumed that the projection unit 121 projects the length L vertically1(cm) width W1(cm) virtual control panel, then, L1、W1Are smaller than the maximum length and the width of the projection area of the letting area of the door body storage box arranged in the refrigerating chamber 112 at the bottom of the refrigerating chamber 112.
As can be seen from fig. 2, in the embodiment of the present invention, the projection module 121 and the sensing module 122 are arranged in the mounting box 124 in parallel, and when the arrangement is specifically performed, the interval between the projection module 121 and the sensing module 122 can be controlled to be smaller than a certain distance, so that the projection plane of the projection module 121 and the detection plane of the sensing module 122 can be overlapped to the maximum extent, and the virtual control panel falls in the overlapping area of the projection plane and the detection plane, so that the operation of the virtual control panel by the user can be effectively detected through the sensing module 122 while the projection is implemented.
In an alternative embodiment of the present invention, the projection assembly 121 as shown in fig. 2 may be configured to emit an infrared signal while projecting the virtual control panel; and the sensing component 122 can be configured to detect user operation in a designated area based on the infrared signal. Specifically, the projection module 121 in this embodiment may be a laser projection module composed of RGB three-color laser emitters, which emits imaging laser and projects a virtual control panel in a designated area. The virtual control panel may present information such as designated images and pictures, and may further include at least one virtual control key, based on which the operation parameters, the function modes, and the like of the refrigerator 100 may be set and selected. In this embodiment, the projection component may also emit an infrared signal during the process of projecting the virtual control panel to the designated area, and if the user touches the virtual control panel, the sensing component 122 may detect a reflected signal of the signal, so as to capture the related operations of the user in the designated area.
In another alternative embodiment of the present invention, the projection assembly 121 may also be configured to project a virtual control panel, which may be a laser projection module, to the designated area; the sensing component 122 may be configured to emit an infrared signal to the designated area and detect a user's operation within the designated area based on the infrared signal. In this embodiment, the sensing component 122 is used to send and receive infrared signals, and cooperate with the projection component 121 to detect the operation of the user in the designated area, so as to identify the operation of the user on the virtual control panel through the processor 123, and generate a corresponding operation instruction for the main control panel of the refrigerator 100 to respond. In this embodiment, the sensing component 122 is internally provided with an infrared emitting module and an infrared receiving module separately, so as to realize the emitting and receiving functions of the infrared signal.
As mentioned above, the virtual projector 120 may be disposed on the top of the refrigerating compartment 112 of the box 110, and preferably, the mounting box 124 may be vertically mounted on the top of the refrigerating compartment 112, such that the bottom surface of the mounting box 124 is disposed parallel to the top surface of the refrigerating compartment 112.
In an alternative embodiment of the present invention, as shown in fig. 4, a receiving portion 113 is provided at the front end of the top of the refrigerating compartment 112, and the mounting box 124 can be received in the receiving portion 113. Further, the bottom surface of the mounting box 124 and the top surface of the refrigerating compartment 112 are disposed in an inclined manner, and the inclined angle may be smaller than a certain included angle, and the included angle may be set according to actual requirements, which is not limited in the present invention. That is to say, in the present embodiment, a groove process may be adopted at the top of the refrigerating compartment 112 of the refrigerator 100, and the mounting box 124 may be disposed at the top of the refrigerating compartment 112 in a half-embedded manner, and is disposed obliquely with respect to the top surface of the refrigerating compartment 112, so as to further reduce the occupied space of the mounting box 124 for the refrigerating compartment 112, and make the mounting box 124 more easily integrated in the refrigerating compartment 112.
Since the projection ratio (α) of the virtual projection device is the projection distance (λ)/the screen width (w), where α is in a range of 1.5-1.9, if the height of the refrigerating room is Hcm, and H is in a range of 70cm-90cm, the width range of the screen projected by the virtual projection device is 36cm-60cm, and the current refrigerator 100 can meet the requirement of the module for projecting the screen size.
In an optional embodiment of the present invention, the refrigerator 100 may further include a door sensing device (not shown in the drawings) configured to detect a door opening event of the refrigerator 100 and generate a door opening signal; and, the projection component 121 is further configured to start after acquiring the door opening signal, so as to project the virtual control panel into the designated area of the storage compartment 111. In this embodiment, the door sensing device is arranged, the door opening signal is generated only when the door opening of the refrigerator 100 is detected, so that the projection assembly 121 projects the virtual control panel when acquiring the door opening signal, and the projection of the virtual control panel to the designated area can be automatically stopped after the door of the refrigerator 100 is closed, so as to further reduce energy consumption and save energy.
In another alternative embodiment of the present invention, as shown in fig. 5, the top of the box 110 has a receiving cavity 114 opened forward, and a virtual projection device 120 telescopically disposed in the receiving cavity 114 and configured to project a virtual control panel to a designated area at the bottom of the refrigerating compartment 112.
In the refrigerator 100 of the present embodiment, the movable projection plate 140 may be disposed in the storage compartment 111, and the virtual projection device 120 may project the virtual control panel onto the projection plate. Generally, the storage compartment 112 is provided with a shelf 141 or a storage drawer 142, and therefore, the projection plate 140 may be disposed at the bottom of the shelf 141, or at the front of the storage drawer 142, or at other positions in the storage compartment 111, which is not limited in the present invention.
In addition to the above, the refrigerator 100 may be provided with a sensor for detecting the temperature of the current indoor environment of the refrigerator, a photosensor for detecting the brightness of the current ambient lighting, and the like. And, the main control board of the refrigerator 100 may acquire other network data information through the connection of the wifi wireless network.
According to the refrigerator 100 provided by the embodiment of the invention, the projection assembly 121 is used for projecting the virtual control panel in the storage compartment 111 of the refrigerator 100, so that the internal function display and the control adjustment of the refrigerator 100 are facilitated, and particularly, when a refrigerator door is in an opened state, the virtual control panel can be projected in a designated area or on the projection plate 140 through the virtual projection device 120 arranged in the storage compartment 111 of the refrigerator body 110, so that different operations of a user of the refrigerator 100 are facilitated, the use requirements of the user are met, and the user experience is improved. Further, in the refrigerator 100 according to the embodiment of the present invention, the virtual projection device 120 is disposed in the middle of the top of the storage compartment 111 of the refrigerator body 110, so that the projection distance of the virtual projection device 120 is shortest, the projection angle is best, and the shielding effect is small. Moreover, by additionally arranging the door sensing device, the projection assembly 121 projects the virtual control panel when acquiring the door opening signal, and the projection of the virtual control panel to the designated area can be automatically stopped after the refrigerator 100 is closed, so that the energy consumption is further reduced, and the energy is saved.
In an alternative embodiment of the present invention, as shown in fig. 6, a lighting controller 150 may be further disposed in the refrigerator 100, and the lighting controller 150 may include a memory and a processor, wherein the memory stores a program, and the program is executed by the processor to implement the lighting control method for the refrigerator compartment according to any one of the following embodiments of the present invention. The lighting controller 150 in this embodiment may be a separately provided controller, or may be integrated with the main control board of the refrigerator 100.
Fig. 7 is a flowchart illustrating a method for controlling lighting of a refrigerator compartment according to an embodiment of the present invention, and referring to fig. 8, the method for controlling lighting of a refrigerator compartment according to the embodiment may include:
s702, projection identification: if the virtual projection device 120 is in a state of projecting the virtual control panel, recognizing the operation of the user on the virtual control panel;
s704, a first illumination step: and adjusting the light emitting parameters of the first light emitting unit and/or the second light emitting unit according to the operation type of the operation of the virtual control panel by the user.
Based on the lighting control method for the refrigerator compartment provided by the embodiment of the invention, the lighting parameters of the first light-emitting unit and the second light-emitting unit in the lighting device 130 can be adaptively adjusted by detecting the operation type of the virtual control panel projected by the user to the virtual projection device 120, so that the virtual projection device 120 provides the best projection effect of the virtual projection panel and simultaneously provides the best visual experience for the user.
In the step S702, since the operation of the virtual control panel by the user is recognized only when the virtual projection apparatus 120 is in a state of projecting the virtual control panel, before the step S702 of recognizing the projection, the method may further include:
a projection step: when the current environment is detected to meet the preset condition that the virtual projection device 120 projects the virtual control panel, the virtual control panel is projected to the designated area at the bottom of the refrigerating compartment through the virtual projection device 120. Wherein the preset condition may be a door opening event of the refrigerator. Optionally, before the projecting step, a door body detecting step may be further included: and detecting a door opening event of the refrigerator through a door body sensing device and generating a door opening signal. Further, when the projection step is executed, the virtual projection device 120 may be started within a specified time after the door opening signal generated by the door body sensing device is acquired, and the virtual control panel may be projected to a specified area at the bottom of the refrigerating compartment through the virtual projection device 120. In this embodiment, the door opening event of the refrigerator is used as the preset condition for the virtual projection device 120 to project the virtual control panel, so that the waste of projection resources when the user opens the door to take an object can be avoided, and the service life of the virtual projection device 120 is prolonged while the projection efficiency is improved. The designated time can be set according to different requirements, and the invention is not limited.
Optionally, the designated area where the virtual control panel is located may be located in a projection area of a letting area of the refrigeration compartment, which is set for the door storage box, at the bottom of the refrigeration compartment. In this embodiment, the designated area is set in the projection area at the bottom of the refrigerating compartment 112, which is a place-giving area set for the door storage box in the refrigerating compartment 112, so that not only the projection component 121 in the virtual projection device 120 can completely project the virtual control panel at the bottom of the refrigerating compartment 112, but also the sensing component 122 can effectively detect the operation of a user in the designated area, thereby effectively reducing or even avoiding the shielding effect of the shelf board in the refrigerating compartment 112 on the projection process of the virtual control panel or the operation process of the user.
As mentioned above, the virtual control panel may include an operation control panel for a user to select related information such as an operation mode and an operation temperature for inputting an article type into the refrigerator, or an information display panel capable of presenting information such as a designated image, a picture, and article storage knowledge. Thus, embodiments of the present invention may provide different illumination schemes for the two different panel types described above.
The S704 first illumination step may include: if the operation of the user on the virtual control panel is recognized as a first operation aiming at the function regulation of any storage chamber, controlling a first light-emitting unit arranged in the storage chamber to emit light for prompting, and adjusting the light-emitting parameters of a second light-emitting unit; if the operation of the user on the virtual control panel is recognized as a second operation for controlling the display of the preset image, acquiring color information of a current image picture of the virtual control panel, and adjusting a light-emitting parameter of a second light-emitting unit based on the color information; the lighting parameters include brightness and/or color temperature.
On the one hand, when virtual control panel is operation control panel, the user can adjust the functional parameter of each storing compartment of refrigerator based on it, and at this moment, generally need not to adopt too complicated illumination light, avoids light can produce the colour difference influence to the projection effect. Therefore, when the operation of the user is detected as the first operation, the white light of the second light-emitting unit can be adjusted, and the brightness is lower than a certain value. When the user adjusts the function of the storage room through the projected virtual control panel, the first light-emitting unit arranged in the adjusted storage room works, and then the user is reminded to operate the room corresponding to the virtual key, so that the operation is visual and clear.
Further, if the operation of the user on the virtual control panel is recognized as a third operation of switching the storage chambers, the first light-emitting unit in the storage chamber is closed, and the first light-emitting unit arranged in the switched storage chamber is controlled to emit light so as to prompt the switched storage chamber which is regulated and controlled currently. That is, when the user switches the adjusted storage compartment, the indicator light-emitting unit of the last adjusted storage compartment is turned off, and the first light-emitting unit of the switched adjusted storage compartment gives a light-on prompt.
On the other hand, when the virtual control panel is an information display panel, the preset image information can be displayed to the user through the panel, and at the moment, the second light-emitting unit is controlled to emit colored light according to the information such as the type and the color of the projection image, so that the image effect is highlighted. For example: when a green leaf picture is projected, the lamp is turned off by adopting yellow to highlight green; when the water flow pattern is formed, light blue can be adopted to highlight the water flow. Or, the illumination colors corresponding to the images with different colors can be preset, and when the color information of the current projected image picture of the virtual control panel is obtained, the preset optimal light corresponding to the color information can be directly selected and projected. When the color information includes a plurality of colors, the colors of the projected light of different second light-emitting units (such as the side wall light-emitting unit and the rear wall light-emitting unit) can be controlled respectively, so that a better viewing effect is provided for a user.
Optionally, after the projecting step, the method may further include: a response step: the operation of a user on the virtual control panel is detected and recognized, and a first operation instruction corresponding to the operation is generated and provided for the main control panel of the refrigerator, so that the main control panel can respond to the operation instruction. The lighting device can identify the operation of the user while providing the lighting, respond to the operation and complete the adjustment of the function of the storage chamber by the user.
As described above, the refrigerator 100 may further include a photosensitive sensor, and optionally, the method of this embodiment may further include a second illumination step: and detecting the brightness information of the environment where the refrigerator is placed through the photosensitive sensor, and adjusting the light-emitting parameters of the second light-emitting unit based on the brightness information. The lighting parameter may be a luminance and/or a color temperature.
That is to say, when the outside is bright, the light can be properly dimmed, and when the outside is dark, the light can be properly dimmed. The brightness of the lamp can be adjusted by the side wall light-emitting unit and the rear wall light-emitting unit in the second light-emitting unit, in addition to the color adjustment of the RGB _ LED lamp. The side wall light-emitting unit and the rear wall light-emitting unit can independently emit light and can also emit light simultaneously, and each light-emitting unit can emit light rays with different brightness and different colors. For example: when both the side wall light-emitting unit and the rear wall light-emitting unit work, the brightness is the maximum, and when only one of the side wall light-emitting unit and the rear wall light-emitting unit works, the brightness is the darkest, and the side wall light-emitting unit and the rear wall light-emitting unit can be set according to different conditions.
In another embodiment of the present invention, a third illumination step may be further included: and acquiring the outdoor temperature and/or the indoor temperature of the current placing environment of the refrigerator, and adjusting the light emitting parameters of the second light emitting unit based on the outdoor temperature and/or the indoor temperature.
For example, the current outdoor temperature may be obtained through the refrigerator main control board connection network to determine the current outdoor temperature state, for example, according to season rotation, light of cool color in summer, light of warm color in winter, and light of medium color in spring and autumn. The user can visually bring cool feeling when the refrigerator is opened under the condition that the outdoor temperature of the room is very high in summer, and the warm atmosphere lamp visually brings warm feeling under the condition that the indoor temperature is low in winter in the same way.
Furthermore, the indoor temperature can be acquired through the temperature sensor, and then the light-emitting parameters of the second light-emitting unit are adjusted in an auxiliary mode through the indoor temperature. That is, after the season is selected, the temperature sensor performs switching between the same-color dimming according to the indoor temperature change, for example, in summer, after the temperature sensor changes by 1 ℃ according to the indoor temperature, the light changes from green to blue, that is, the scheme provided by this embodiment may determine the color tone of the second light-emitting unit according to the outdoor temperature, and further adjust the color temperature according to the indoor temperature, so as to improve the projection effect.
