Detailed Description

Fig. 1 is a schematic structural diagram of a refrigerator 100 according to an embodiment of the present invention, and as can be seen from fig. 1 to 3, the refrigerator 100 according to an embodiment of the present invention may include: a box 110, a virtual projection device 120, and a heating device 130. The box body 110 defines a storage compartment 111. The virtual projection device 120 is disposed in the storage chamber 111, and includes: a projection unit 121 configured to project a virtual control panel in 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. And a heating device 130 configured to remove dew from the virtual projection device 120.

According to the refrigerator 100 with the internal projection function 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 in the door opening state of the refrigerator 100, the virtual control panel can be projected in the designated 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 requirements of the user are met, and the user experience is improved. In addition, the virtual projection device 120 may have a projection lens to implement projection of the virtual control panel, and in this embodiment, the heating device 130 is disposed to remove dew from the virtual projection device 120, so as to implement internal projection of the refrigerator 100 and solve the problem of condensation of the projection lens of the virtual projection device 120.

Optionally, in this embodiment, the processor 123 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 122, 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 122 to detect, judge whether the virtual control panel is operated by a user according to data detected by the sensing assembly 122, and further send a corresponding operation instruction to the main control board of the refrigerator 100.

The virtual control panel projected by the projection component 121 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, the operation parameter of the refrigerator 100, and may also 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 121 may further have a plurality of touch keys to set the regulation and control requirements and the display requirements of different operation scenes of the refrigerator 100.

In an embodiment of the present invention, 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. Fig. 2 shows a schematic structural diagram of the virtual projection apparatus 120. As can be seen from fig. 1-2, the virtual projection apparatus 120 may further include a mounting box 124 defining a receiving space 140, and the projection assembly 121, the sensing assembly 122, and the processor 123 of the virtual projection apparatus 120 may be disposed in the receiving space 140. The mounting box 124 may be provided with a transparent box cover, or the transparent box cover is disposed at a position where the projection component 121 and the sensing component 122 are corresponding to the box cover of the mounting box 124, and the projection component 121 and the sensing component 122 are tightly attached to the transparent box cover, and the projection component 121 and the sensing component 122 are arranged in the accommodating space 140 in parallel and are located at one side of the mounting box 124 close to the door of the refrigerator 100. The mounting box 124 may be disposed at a middle position of the top of the refrigerating compartment 112 within a predetermined distance range from the front end of the cabinet 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 body 110 is within a preset distance range, and the preset distance range 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 does not deform, and considering the influence of the spacer rack items on the projection, the distance M (cm) from the front end of the box 110110 (specifically, the outer edge of the top of the refrigerator 100), where M < W/2, is to prevent the bottle seat of the refrigerating compartment from colliding.

As can be seen from fig. 1 and 6, the designated area of the projection assembly 121 projecting the virtual control panel to the storage compartment 111 is located at the bottom of the refrigeration compartment 112; the projection assembly 121 and the sensing assembly 122 respectively 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. Optionally, the designated area of the projection module 121 projecting the virtual control panel to the storage compartment 111 is preferentially located in the projection area of the refrigerator compartment 112 at the bottom of the refrigerator compartment 112, which is a relief area of the door storage box, so that the projection distance of the virtual projection device 120 is shortest, the projection angle is best, and the shielding effect is small.

In practical applications, since the door of the refrigerator 100 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 a leaving area for the door storage box, so that the door storage box is arranged in the leaving area of the refrigerating chamber 112 after the door of the refrigerator 100 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.

As shown in fig. 6, the designated area at the bottom of the refrigerating compartment 112 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 projection component 121121 is located within region 4. Assume that projection assembly 121 projects length L vertically ₁ (cm) width W ₁ (cm) virtual control panel, then, L ₁ 、W ₁ Are smaller than the maximum length and the width of the projection area of the letting area of the cold door body storage box in the bottom of the cold storage 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 disposed in the accommodating space 140 of the mounting box 124 in parallel, and when the embodiment is specifically disposed, 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 realized.

As described above, the refrigerator 100 may further include a heating device 130 to remove dew from the virtual projection device 120. Referring to fig. 3, the heating device 130 may include at least a portion of a dew-removing pipe 131 disposed in the case 110. The dew-removing pipe 131 extends to the accommodating space 140 based on the side wall of the mounting box 124; and a fan 132 disposed in the accommodating space 140 and configured to promote an airflow carrying a portion of the heat of the dew removing pipe 131 in the accommodating space 140.

Generally, since the edge of the door of the refrigerator 100 may drop in wet weather, the dew-removing pipe 131 is usually designed at the edge of the door of the refrigerator 100 and connected to the condenser, and during the refrigeration process of the refrigerator 100, the high-pressure gas refrigerant flows through the pipe to generate heat, so as to prevent the drop and remove dew. Dew condensation removing pipe 131 is a relatively important part of refrigerator 100, and is mainly installed at the front side of cabinet 110 of refrigerator 100, so as to prevent the occurrence of dew condensation at the outer edge of the door of refrigerator 100 due to an excessive difference between the inside temperature and the outside temperature.

In the present embodiment, by extending the dew condensation removing pipe 131 existing in the refrigerator 100 into the accommodating space 140 of the mounting box 124 as a part of the heating device 130, the projection module 121 can be dew-removed by heat generated during its operation. Alternatively, referring to fig. 3 and 4, the dew-removing pipe 131 may extend vertically into the accommodating space 140 of the mounting box 124, which is mainly located at a position where the accommodating space 140 is close to the rear wall of the refrigerating space. Further, the heating device 130 may further include a fan 132 to promote the formation of an air flow carrying a portion of the heat generated by the dew condensation removing pipe 131 in the accommodating space 140. Wherein, the projection assembly 121 and the sensing assembly 122 may be located at a front end of the accommodating space 140, i.e., near a front edge of the main body of the refrigerator 100. The fan 132 may be located in front of the dew-removing pipe 131, and located between the projection assembly 121 and the dew-removing pipe 131, and specifically may be disposed in an inclined manner with respect to the dew-removing pipe 131, that is, the fan 132 is disposed in the accommodating space 140 in an inclined manner, so as to increase the blowing area.

As can be seen with continued reference to fig. 3-4, the heating device 130 further includes at least one baffle 133 disposed in the accommodating space 140, and the baffle 133 may surround the wall of the mounting box 124 to form a return air space 134. Referring to fig. 4, when the mounting box 124 has a square shape, the return air spaces 134 may be formed at two corners of the accommodating space 140, which are on the same diagonal line. In practical applications, the shape of the mounting box 124 may be varied, and the arrangement positions of the air return space 134, the dew removing pipe 131, the fan 132, the projection assembly 121, the sensing assembly 122, and the processor 123 in the accommodating space 140 of the mounting box 124 may be reasonably adjusted according to different requirements, which is not limited in the present invention.

Referring to fig. 3-4, the baffle 133 is respectively provided with an air inlet 151 and an air return 152. After the fan 132 is rotated to form an airflow, part of the airflow enters the return air space 134 through the air inlet holes 151 and returns to the accommodating space 140 from the return air holes 152, and an airflow circulation is formed, as shown by the dotted arrows in fig. 4. The air inlet 151 may be located near the projection assembly 121, the air return 152 may be located near the fan 132, and the number of the air inlet 151 and the air return 152 may be set according to different requirements, which is not limited in the present invention. In this embodiment, by providing the guide plate in the accommodating space 140, on the one hand, the fan 132 can be limited to cause the flowing direction of the air flow to be formed, and the air flow carrying heat is concentrated to flow to the projection component 121, on the other hand, the opening is adopted to form the air return space 134, so that the air flow circulation is formed in the accommodating space 140, and the dew removal of the projection component 121 is rapidly and effectively realized.

Optionally, the heating device 130 in the embodiment of the present invention may adopt a heat insulation process to reduce the heat exchange between the mounting box 124 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 124. In the heat insulation treatment, a heat insulation layer may be added on the inner surface or the outer surface of the mounting box 124, and the invention is not limited thereto.

The dew-removing tube 131 may generate heat when the refrigerator 100 is in operation, and when the refrigerator 100 is closed, the virtual projector 120 may be in a sleep state, and at this time, the blower 132 may start to operate for T seconds every M seconds to accelerate the hot airflow to the lens of the projection assembly 121. In practical applications, the refrigerator 100 further includes: a temperature sensor (not shown in the figures) is provided in the refrigerating compartment 112, the temperature sensor being configured to detect a temperature of the refrigerating compartment 112. And the fan 132 may also be configured to adjust its operating state based on the temperature of the refrigerated compartment 112. Optionally, the temperature sensor and the fan 132 may be in communication connection based on a main control board of the refrigerator 100, that is, the temperature sensor may be in communication connection with the main control board of the refrigerator 100, and the specific wire harness of the fan 132 may also be connected to the main control board of the refrigerator 100, so that the main control board of the refrigerator 100 controls the working state of the fan 132 based on the temperature collected by the temperature sensor.

In this embodiment, the fan 132 may have two working states, i.e., a first working state in a normal state and a second working state in a special state. The first operating state is an operating state in which the temperature of the refrigerating compartment 112 is lower than a first preset temperature, and the second operating state is an operating state in which the temperature of the refrigerating compartment 112 is lower than a second preset temperature. The first preset temperature and the second preset temperature may be set according to different use environments and sizes of the refrigerator 100, which is not limited in the present invention. For example, the first preset temperature may be M1, and the second preset temperature may be M2, where M1> M2. When the temperature of the refrigerating compartment 112 detected by the temperature sensor is lower than M1, the fan 132 is in the first working state, that is, the fan 132 is turned on for N1 seconds every T1 seconds; when the temperature of the refrigerating compartment 112 detected by the temperature sensor is lower than M2, it indicates that the refrigerating compartment 112 is in a deep cooling state, and at this time, the fan 132 will adjust the working state to a second working state, that is, the fan 132 is turned on for N2 seconds every T2 seconds; wherein T1> T2, N1< N2. In addition, if the temperature sensor fails, the fan 132 is preferentially in the first working state, and even if the fan 132 stops working and does not supply air, the heat of the condenser is also radiated to the lens of the projection assembly 121; when the refrigerator 100 is opened, the projection unit 121 is operated and the blower fan 132 should be stopped. In this embodiment, by controlling the operating state of the fan 132 based on the temperature of the refrigerating compartment 112, the heating device 130 can adaptively control the blowing time and frequency of the fan 132, so as to further improve the dew removal effect of the virtual projection device.

In an alternative embodiment of the present invention, the projection module 121 shown in fig. 2 may include: a first laser projection assembly 161 configured to project a virtual control panel to a designated area and emit an infrared signal; and the sensing assembly 122 may include a first infrared receiving assembly 162 configured to detect a user's operation in a designated area based on the infrared signal. Specifically, the first laser projection module 161 in the present embodiment may be a laser projection module 121 composed of RGB three-color laser emitters for emitting imaging laser and projecting 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 first laser projection element 161 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 first infrared receiving element 162 may detect the blocking 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, as shown in fig. 7, the projection assembly 121 may include a second laser projection assembly 163 configured to project a virtual control panel to a designated area; sensing component 122 can include an infrared emitting component 164 and a second infrared receiving component 165. Wherein, the infrared emission component 164 is configured to emit infrared signals to the designated area; and a second infrared receiving component 165 configured to detect a user's operation in a designated area based on the infrared signal. In this embodiment, the projection of the virtual control panel or other image information is realized by the second laser projection component 163, the infrared emission component 164 and the second infrared receiving component 165 cooperate to realize the transmission and reception of infrared signals, and the detection of the operation of the user in the designated area is realized by the cooperation of the three components, so that the processor 123 identifies the operation of the virtual control panel by the user, and generates a corresponding operation instruction for the main control panel of the refrigerator 100 to respond. In this embodiment, the signal projection or signal collection areas of the second laser projection element 163, the infrared emission element 164 and the second infrared reception element 165 also have an overlapping area, and the virtual control panel is also in the overlapping area of the three elements. Unlike the embodiment shown in fig. 2, a separate infrared emission component 164 is provided in this embodiment to implement the infrared signal emission function. The second infrared receiving component 165 and the first infrared receiving component 162 may be the same type of infrared receiving module having an infrared receiving function.

In any of the above manners, when the sensing assembly 122 detects based on the infrared signal, the sensing assembly can first obtain the reflection signal of the infrared signal, and then recognize the operation of the user based on the received reflection signal. In practical application, when the sensing component 122 acquires the reflection signal, an average filtering method can be adopted for the acquired signal data to eliminate abnormal values and improve the measurement accuracy, so that the problem of condensation of the projection component 121 is solved and the interference of hot air on the infrared sensor is prevented. And (3) eliminating abnormal values by adopting mean filtering, namely defining a fixed-length array (such as the length is 10 or other values), defining a threshold value R, selecting a middle number from the array as a representative, making a difference between each element of the array and the middle number, eliminating the abnormal values when the difference value is higher than R, averaging the screened values to be used as actual values, and participating in control.

For example, the signal data corresponding to the reflection signal received by the sensing component 122 are data 1, data 2, and data 10, respectively, and each group of data includes the acquisition time of the reflection signal and the corresponding signal strength. The data 1 to the data 10 are sorted according to the signal intensity, the data x with the middle number such as the 5 th sorted data is selected as a representative, the signal intensity of the data except the data x from the data 1 to the data 10 is respectively differed, when the difference value is higher than R, the abnormal value is to be removed, then the signal intensities corresponding to other data are averaged to obtain a to-be-judged reflection signal, and then the operation of a user is detected and identified based on the to-be-judged reflection signal, so that the detection efficiency and the detection accuracy are improved.

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. 8, a mounting portion 113 is provided at the front end of the top of the refrigerating compartment 112, and the mounting box 124 is received in the mounting 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 120 is the projection distance (λ)/the screen width (w), where α is in a range of 1.5-1.9, and if the height of the refrigerating compartment is Hcm, and H is in a range of 70cm-90cm, the width of the screen projected by the virtual projection device 120 is in a range of 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 with the internal projection function 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.
