In this embodiment, the virtual control panel is projected onto the transparent cover plate 130, so that the user can directly trigger the virtual projection panel on the transparent cover plate 130 to adjust the functional mode of the refrigerator.
In an alternative embodiment of the present invention, as shown in fig. 2, the virtual projection apparatus 120 may include a projection component 121, a reflection component 122, a sensing component 123, and a processor 124, wherein the projection component 121 is configured to project a virtual control panel; a reflection assembly 122 disposed on a projection path of the projection assembly 121, and configured to obtain a virtual control panel projected by the projection assembly 121 and reflect the virtual control panel to a designated area at the bottom of the refrigerating compartment 112; a sensing component 123 configured to detect user operations in a designated area; and a processor 124, communicatively connected to the projection component 121 and the sensing component 123, configured to recognize an operation of the virtual control panel by the user according to a detection result of the sensing component 123, and generate an operation instruction corresponding to the operation to be provided to the main control panel of the refrigerator 100, so that the main control panel responds to the operation instruction.
Optionally, in this embodiment, the processor 124 in the virtual projection apparatus 120 is mainly used as a core data processing component of the virtual projection apparatus 120, and is in communication connection with the projection assembly 121 and the sensing assembly 123, and may also be in communication connection with a main control board of the refrigerator 100, so as to control the projection assembly 121 to project, control the sensing assembly 123 to detect, judge whether the virtual control panel is operated by a user according to data detected by the sensing assembly 123, and further send a corresponding operation instruction to the main control board of the refrigerator 100.
With continued reference to fig. 2, the virtual projection apparatus 120 may further include a mounting box 125 defining a receiving space 126, and the projection assembly 121, the sensing assembly 123, the reflection assembly 122, and the processor 124 of the virtual projection apparatus 120 may be disposed in the receiving space 126. The mounting box 125 is disposed in the accommodating cavity 113, and a side of the mounting box 125 facing the refrigerating compartment 112 is a transparent box wall for the virtual projection device 120 to project a virtual control panel through the transparent box wall.
In this embodiment, the projection element 121, the reflection element 122 and the sensing element 123 may be sequentially disposed, and each of the elements has a certain distance therebetween, and the three elements may be on a horizontal line. Assuming that the projection module 121, the reflection module 122 and the sensing module 123 are sequentially disposed in the mounting box 125 from left to right, and the projection lens of the projection module 121 and the reflection module 122 are disposed opposite to each other, that is, the projection direction of the projection module 121 is the direction of the reflection module 122, the projection module 121 can horizontally project the virtual control panel to the right onto the reflection module 122, and the reflection module 122 reflects the virtual control panel to the transparent cover 130 through the transparent box wall of the mounting box 125, so that the user can operate the virtual control panel. In addition, the sensing assembly 123 is located on the right side of the reflection assembly 122, which can collect the user's operation of the virtual control panel on the top transparent cover 130 thereof via the transparent box wall of the installation box 125. The reflecting assembly 122 may be a gold film off-axis parabolic mirror, and may realize offset angles of 15 degrees, 30 degrees, 45 degrees, 60 degrees, and 90 degrees, and the inclination angle of the reflecting mirror with respect to the projecting assembly 121 may be adjusted according to the projection area on the transparent cover 130, which is not limited in the present invention.
In an alternative embodiment of the present invention, the projection module 121 shown in fig. 2 may be configured to project a virtual control panel to a designated area and emit an infrared signal; and the sensing element 123 may be configured to detect a user's operation in a designated area based on the infrared signal. Specifically, the projection module 121 in this embodiment may be a laser projection module 121 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 121 may also emit an infrared signal during the process of projecting the virtual control panel to the designated area, and assuming that the user touches the virtual control panel, the sensing component 123 may detect a reflected signal of the signal, thereby capturing 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 member 123 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 123 is used to send and receive infrared signals, and cooperates 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 124, and generate a corresponding operation instruction for the main control panel of the refrigerator 100 to respond. In this embodiment, the sensing component 123 is internally provided with an infrared emitting module and an infrared receiving module, so as to realize the emitting and receiving functions of the infrared signal.
As mentioned above, the virtual projection device 120 is mainly a projection virtual control panel to the transparent cover 130, wherein the designated area may be a relief area provided for the door storage box in the refrigeration compartment in the projection area at the bottom of the refrigeration compartment. 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 this embodiment, the designated area of the virtual projection device 120 projecting the virtual control panel to the bottom of the refrigerating compartment 112 is preferentially located in the projection area of the letting area of the refrigerating compartment 112, which is set for the door storage box, at the bottom of the refrigerating compartment 112, so that not only can the virtual projection device 120 completely project the virtual control panel at the bottom of the refrigerating compartment 112, but also the space of the refrigerating compartment 112 can be reasonably utilized.
When a user touches the virtual control panel on the transparent cover plate 130 with a hand, the infrared signal passing through the transparent cover plate 130 is blocked and then reflected to the sensing component 123, the fingers of the user trigger the virtual keys at different positions on the transparent cover plate 130, the angles at which the fingers block the infrared signal are different, the strength of the signal reflected to the sensing component 123 is also different, and the processor 124 can distinguish the function of the virtual keys according to the strength of the reflected signal received by the sensing component 123. Further, the projection path and the infrared signal receiving path in this embodiment are both inside the accommodating cavity 113, so that there is no need to consider the problem that the object stored in the refrigerator can block the projection path of the projection assembly 121 and the sensing path of the sensing assembly 123.
As can be seen from fig. 1 to 2, the refrigerator 100 according to the embodiment of the present invention may further include a heating device 140 configured to remove dew from the virtual projection device 120, so as to implement the projection inside the refrigerator 100 and solve the problem of condensation on the projection lens of the virtual projection device 120. The heating device 140 may include at least a portion of the dewing pipe 141 disposed inside the case 110. The dew-point removal pipe 141 extends to the housing space 126 based on the side wall of the mounting case 125.
Generally, because the edge of the door body of the refrigerator can generate water drops in wet weather, the dew removing pipe 141 is mostly designed at the edge of the door body of the refrigerator and is connected with the condenser, and high-pressure gas-shaped refrigerant can flow through the pipe in the refrigeration process of the refrigerator, so that heat is generated, the purpose of preventing the water drops from occurring is realized, and the dew removing effect is realized. The dew removing pipe 141 is an important part of the refrigerator, and is mainly installed at the front side of the refrigerator body 110 of the refrigerator to prevent the occurrence of dew at the outer edge of the door body of the refrigerator due to an excessive temperature difference between the inside and the outside.
In the present embodiment, by extending the dew condensation removing tube 141 existing in the refrigerator into the accommodating space 126 of the mounting box 125 as a part of the heating device 140, the projection module 121 can be dew-removed by heat generated during its operation. Optionally, the heating device 140 in the embodiment of the present invention may adopt a heat insulation process to reduce the heat exchange between the mounting box 125 and the refrigerating compartment 112, and avoid the influence of the temperature of the refrigerating compartment 112 on the compartment temperature due to the temperature increase of the mounting box 125. Specifically, when the heat insulation treatment is performed, a heat insulation layer may be additionally provided on the inner surface or the outer surface of the mounting box 125, but the present invention is not limited thereto.
In practical applications, the shape of the mounting box 125 may be varied, and it may be adapted to the accommodating cavity 113, such as a square or other shape. The positions of the projection assembly 121, the sensing assembly 123, the processor 124 and the reflection assembly 122 in the receiving space 126 of the mounting box 125 can be adjusted according to different requirements, and the invention is not limited thereto. In this embodiment, each component in the virtual projection apparatus 120 can be integrated together through the mounting box 125, and the position of each component is reasonably arranged, so that the space occupied by the virtual projection apparatus 120 inside the refrigerator can be greatly reduced.
In an optional embodiment of the present invention, the refrigerator 100 with the internal projection function may further include a door sensing device (not shown in the drawings), which is in communication connection with the virtual projection device 120, and is configured to detect a door opening event of the refrigerator 100 and generate a door opening signal; the virtual projection device 120 is further configured to activate after acquiring the door opening signal to project the virtual control panel into the designated area at the bottom of the refrigerating compartment 112, for example, the virtual control panel may be projected three seconds or five seconds after the refrigerator is opened. 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 virtual projection device 120 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.
The refrigerator 100 with the internal projection function provided by the embodiment of the invention has the advantages that the virtual projection device 120 is arranged at the bottom of the refrigerating chamber 112, so that not only can a virtual control panel be projected to meet the use requirements of users while the external door structure of the refrigerator is not influenced, but also the occupied space of the virtual projection device 120 in the refrigerator 100 can be reduced by arranging the virtual projection device 120 in the accommodating cavity 113 at the bottom of the refrigerating chamber 112.
Further, in the embodiment of the present invention, the door sensing device is additionally arranged to project the virtual control panel when the projection assembly 121 obtains the door opening signal, and the projection of the virtual control panel to the designated area can be automatically stopped after the refrigerator is closed, so as to further reduce energy consumption and save energy. In addition, in the embodiment, the heating device 140 is provided to remove dew from the virtual projection device 120, so that the problem of condensation on the projection lens of the virtual projection device 120 is solved while the refrigerator interior is projected.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
