[0039] Unless otherwise specified, the term "plurality" means two or more.
[0040] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.
[0041] Combined with Figure 1-3 As shown in the figure, the embodiment of the present disclosure provides an imaging module for a refrigerator, including: a protection box 100, a negative refraction lens 200, a display screen 300, and an infrared sensor 400. The protection box 100 is installed on the door body 500 of the refrigerator, and an installation hole 101 is provided on one side of the protection box 100, and an installation groove 102 is provided on the inner side wall; the negative refraction lens 200 is arranged in the installation hole 101; the display screen 300 is arranged in the installation groove 102; the infrared sensor 400 is arranged on the side wall of the protection box 100 where the installation hole 101 is provided, and a set angle is formed between the light beam emitted by the infrared sensor 400 and the display surface of the display screen 300, and the negative refraction lens 200 is located on the angular bisector of the set angle.
[0042] By using the imaging module for a refrigerator provided by the embodiment of the present disclosure, the image displayed on the display surface of the display screen 300 is refracted by the negative refraction lens 200 into the air outside the protection box 100 to form an imaging surface 301. And the light beam emitted by the infrared sensor 400 coincides with the imaging surface 301. The user can drive an object to the imaging surface 301, click on the corresponding interface position on the imaging surface 301, and sense and determine the interface position clicked by the object through the reflection of the light beam by the item, and then correspondingly adjust the operating parameters of the refrigerator. This avoids the user directly contacting the display screen 300, reduces the water stains and food residues remaining on the refrigerator due to contact, reduces the growth of bacteria, and improves the user experience.
[0043] It can be understood that the display screen 300 is in the installation groove 102, and the installation groove 102 provides limit and support for the display screen 300, reducing the risk of the display screen 300 shaking and ensuring the effect of aerial imaging.
[0044] Optionally, a first included angle 103 is provided between the display surface of the display screen 300 and the negative refractive lens 200; a second included angle 104 is provided between the light beam emitted by the infrared sensor 400 and the negative refractive lens 200; wherein, both the first included angle 103 and the second included angle 104 are greater than or equal to 25° and less than or equal to 35°. In this way, the first included angle 103 is equal to the second included angle 104, so that the light beam emitted by the infrared sensor 400 coincides with the imaging surface 301, improving the operation accuracy. When the first included angle 103 is less than 25°, the distance between the display screen 300 and the negative refractive lens 200 is too close, resulting in the distance between the imaging surface 301 and the door body 500 being too close, and the risk of the user accidentally touching the door body 500 is relatively high. When the first included angle 103 is greater than 35°, the included angle between the display screen 300 and the negative refractive lens 200 also needs to be adjusted correspondingly, so that the included angle between the display screen 300 and the horizontal direction is relatively small, and the space occupied by the display screen 300 facing the rear side of the door body 500 is relatively large. Therefore, it can be seen that the range where the first included angle 103 is greater than or equal to 25° and less than or equal to 35° is relatively reasonable. The distance between the imaging surface 301 and the door body 500 is relatively far, reducing the risk of the user accidentally touching the door body 500 and facilitating the user to observe the imaging surface 301.
[0045] Optionally, the first included angle 103 is equal to 30°. In this way, the distance between the imaging surface 301 and the door body 500 is relatively far, reducing the risk of the user accidentally touching the door body 500. And the included angle between the imaging surface 301 and the horizontal plane is 30°, the included angle between the display screen 300 and the horizontal direction is relatively large, and the space occupied by the display screen 300 facing the rear side of the door body 500 is relatively small.
[0046] Combined Figure 4 and Figure 5 As shown in the figure, optionally, a maintenance opening 105 is provided at the rear side wall of the protection box 100 corresponding to the display screen 300, and a cover plate 110 covering the maintenance opening 105 is provided on one side of the protection box 100. In this way, it is convenient to perform maintenance on the display screen 300 in the protection box 100 through the maintenance opening 105.
[0047] Optionally, the other side surface opposite to the display surface of the display screen 300 is arranged facing the maintenance opening 105. In this way, the other side surface opposite to the display surface of the display screen 300 is the back surface of the display screen 300. Since there are relatively more parts on the back surface of the display screen 300, it is relatively more convenient to perform maintenance on the display screen 300.
[0048] Optionally, at the position corresponding to the display screen 300 on the cover plate 110, there is a first covering portion 111, and the first covering portion 111 is arranged parallel to the display screen 300. In this way, the gap between the display screen 300 and the first covering portion 111 can be set relatively small, and the relatively small gap facilitates the protection box 100 to reduce its overall volume. It reduces the space occupied by the refrigerator door body 500 and the interior of the refrigerator compartment, and the setting of the position of the protection box 100 on the door body 500 is also more flexible.
[0049] Specifically, the first covering portion 111 is arranged parallel to the other side surface of the display screen 300 opposite to the display surface. In this way, the gap between the back surface of the display screen 300 and the first covering portion 111 can be set relatively small, and the relatively small gap facilitates the protection box 100 to reduce its overall volume. It reduces the space occupied by the refrigerator door body 500 and the interior of the refrigerator compartment, and the setting of the position of the protection box 100 on the door body 500 is also more flexible.
[0050] Optionally, the display screen 300 cooperates with the installation groove 102 to divide the inside of the protection box 100 into a first chamber 106 and a second chamber 107, and the first chamber 106 communicates with the installation hole 101. In this way, the installation groove 102 provides support and limit for the display screen 300, reducing the risk of the display screen 300 shaking and displacing relative to the protection box 100 during the opening or closing process of the door body 500. And the inside of the protection box 100 is divided into the first chamber 106 and the second chamber 107, improving the sealing performance between the display surface and the negative refraction lens 200, reducing the risk of dust entering between the display surface and the negative refraction lens 200, and ensuring the imaging effect.
[0051] Optionally, the maintenance port 105 communicates with the second chamber 107. In this way, after the cover plate 110 is opened, the display screen 300 in the second chamber 107 can be maintained, reducing the influence on the first chamber 106, reducing the risk of dust entering the first chamber 106 during the maintenance process, and ensuring the imaging effect.
[0052] Optionally, in the horizontal direction, the length of the part of the protection box 100 corresponding to the second chamber 107 is greater than the length of the part of the protection box 100 corresponding to the first chamber 106; in the vertical direction, the length of the part of the protection box 100 corresponding to the second chamber 107 is less than the length of the part of the protection box 100 corresponding to the first chamber 106. In this way, the length of the part of the protection box 100 corresponding to the first chamber 106 is relatively long, enabling the negative refraction lens 200 and the display screen 300 to be set with a relatively long length, and having a better integrity with the door body 500.
[0053] It can be understood that the protection box 100 is installed on the door body 500, and the projection of the protection box 100 on the front side wall of the door body 500 is T-shaped.
[0054] Optionally, one side wall of the protection box 100 provided with the mounting hole 101 is provided with a plug-in slot 108, and the infrared sensor 400 is plugged into the plug-in slot 108. In this way, the infrared sensor 400 is plugged into the plug-in slot 108, and the risk of the infrared sensor 400 shaking and displacing relative to the protection box 100 is relatively low, thereby ensuring that the infrared sensor 400 can accurately sense the user's click on the imaging surface 301 and reducing the risk of misidentification.
[0055] Optionally, a control board 120 is provided inside the protection box 100, and the control board 120 is electrically connected to the display screen 300 and the infrared sensor 400. In this way, the infrared sensor 400 sends the sensed signal to the control board 120, and the control board 120 correspondingly adjusts the operating parameters of the refrigerator to improve the user experience.
[0056] Specifically, the control board 120 is located in the second chamber 107, and the control board 120 is located on the other side surface opposite to the display surface of the display screen 300. In this way, after the cover plate 110 is opened, it is more convenient to repair the control board 120 in the second chamber 107, reduce the influence on the first chamber 106, reduce the risk of dust entering the first chamber 106 during the repair process, and ensure the imaging effect.
[0057] Optionally, a connection bracket 130 is provided inside the protection box 100, and the control board 120 is connected to the connection bracket 130. In this way, the control board 120 and the protection box 100 are connected through the connection bracket 130, increasing the distance between the protection box 100 and the control board 120 and improving the heat dissipation effect of the control board 120.
[0058] Combined with Figure 6 As shown, optionally, one side wall of the protection box 100 is provided with a wire harness hole 109. In this way, through the wire harness hole 109, it is convenient to electrically connect the display screen 300 and the infrared sensor 400 inside the protection box 100 to other components of the refrigerator. For example, electrically connect to the power supply of the refrigerator.
[0059] Specifically, the wire harness hole 109 communicates with the second chamber 107. In this way, it is avoided that the wire harness affects the imaging effect in the first chamber 106.
[0060] In some embodiments, the refrigerator includes: an imaging module for the refrigerator as described in any one of the above embodiments.
[0061] When using the refrigerator provided by the embodiments of the present disclosure, since the refrigerator includes the imaging module for the refrigerator as described in any of the above embodiments, it can display the image shown on the display surface of the display screen 300, which is refracted by the negative refraction lens 200 into the air outside the protection box 100 to form an imaging surface 301. Moreover, the light beam emitted by the infrared sensor 400 coincides with the imaging surface 301. The user can drive an object to the imaging surface 301, click on the corresponding interface position on the imaging surface 301, and sense and determine the interface position clicked by the object through the situation of the light beam reflected by the article, and then correspondingly adjust the operating parameters of the refrigerator. This avoids the user directly contacting the display screen 300, reduces the water stains and food residues remaining on the refrigerator due to contact, reduces the growth of bacteria, and improves the user experience.
[0062] Combined Figure 7 As shown, optionally, the refrigerator further includes: a door body 500. A through hole 501 is provided on the front side wall of the door body 500, and the mounting hole 101 of the protection box 100 is embedded in the door body 500 corresponding to the through hole 501. In this way, the position of the mounting hole 101 corresponds to the position of the through hole 501, and the image displayed on the display screen 300 can be displayed in the air in front of the door body 500 through the through hole 501, avoiding the influence of the door body 500 on the imaging effect. Moreover, the protection box 100 is embedded in the door body 500, reducing the occupation of the internal space of the refrigerator compartment.
[0063] It can be understood that the protection box 100 is embedded in the door body 500, making the height of the protection box 100 protruding from the door body 500 relatively low, reducing the occupation of the internal space of the refrigerator compartment, and the foaming layer of the door body 500 can also provide heat preservation and heat insulation for the protection box 100, reducing the risk of condensation in the protection box 100. The protection box 100 can also directly lay the wire harness in the door body 500 through the wire harness hole 109, avoiding the wire harness being exposed outside.
[0064] Optionally, both the protection box 100 and the negative refraction lens 200 are abutted against the front inner side wall of the door body 500. In this way, when the refrigerator is refrigerated, the temperature on the front side of the door body 500 is higher than the temperature on the rear side of the door body 500. And the negative refraction lens 200 is relatively close to the front side wall of the door body 500, making the temperature in the negative refraction lens 200 and the first chamber 106 relatively high, reducing the risk of condensation due to the low temperature in the negative refraction lens 200 and the first chamber 106, and ensuring the imaging effect.
[0065] Optionally, along the vertical direction, the length of the through hole 501 is less than the length of the negative refraction lens 200. In this way, the edge of the through hole 501 can provide support for the negative refraction lens 200, reducing the risk of the negative refraction lens 200 falling off from the through hole 501.
[0066] Optionally, the refrigerator further includes a transparent protection plate 510. The transparent protection plate 510 is disposed within the through hole 501. In this way, the transparent protection plate 510 can provide protection for the negative refraction lens 200, reducing the risk of the negative refraction lens 200 being bumped and scratched, and ensuring the imaging effect.
[0067] In one embodiment, the transparent protection plate 510 is integrally formed with the front side wall of the door body 500. In this way, the connection strength between the transparent protection plate 510 and the door body 500 is relatively high, and there are relatively few seams on the door body 500, making the integrity of the door body 500 better and the user experience better.
[0068] Combined with Figure 8 As shown, in another embodiment, the transparent protection plate 510 is a transparent glass plate 511. In this way, the transparent glass plate 511 has good light transmittance, ensuring the imaging effect. And the texture of the transparent glass plate 511 is relatively hard, reducing the risk of being scratched.
[0069] Optionally, a support plate 520 is fixedly provided on the rear inner side wall of the door body 500. The support plate 520 is located below the protection box 100 to provide upward support for the protection box 100. In this way, the support plate 520 provides support for the protection box 100, improving the stability of the protection box 100 disposed within the door body 500.
[0070] Optionally, the support plate 520 extends from the rear inner side wall of the door body 500 to the front inner side wall of the door body 500. In this way, the support plate 520 provides a larger range of support for the protection box 100. And one end of the support plate 520 is connected to the rear inner side wall of the door body 500, and the other end of the support plate 520 abuts against the front inner side wall of the door body 500. In the case where the support plate 520 provides support for the protection box 100, the risk of bending deformation of the support plate 520 is reduced.
[0071] Combined with Figure 9 And Figure 10 As shown, optionally, a support frame 530 is provided on one side of the support plate 520. The support frame 530 surrounds the outside of the protection box 100 and is fixedly connected to the rear inner side wall of the door body 500. In this way, the support frame 530 and the support plate 520 cooperate to provide support and limit for the protection box 100, reducing the risk of the protection box 100 shaking and displacing relative to the door body 500, and ensuring the imaging effect. And the support frame 530 is connected to the support plate 520, improving the structural strength of the support plate 520 and reducing the risk of bending deformation of the support plate 520.
[0072] Optionally, the upper end portion of the support frame 530 extends from the rear inner wall of the door body 500 to the front inner wall of the door body 500. In this way, in cooperation with the support plate 520 extending from the rear inner wall of the door body 500 to the front inner wall of the door body 500, support is provided between the front side wall and the rear side wall of the door body 500, reducing the risk of the door body 500 being dented and deformed.
[0073] Optionally, a limiting groove 502 is provided on the rear inner wall of the door body 500, and a part of the protection box 100 is located in the limiting groove 502. In this way, the limiting groove 502 can provide limitation and support for the protection box 100, reducing the risk of the protection box 100 shaking and displacing relative to the door body 500 and ensuring the imaging effect.
[0074] Specifically, the limiting groove 502 is located between the support frame 530 and the support plate 520. In this way, the limiting groove 502 cooperates with the support frame 530 and the support plate 520, reducing the risk of the protection box 100 shaking and displacing relative to the door body 500 and ensuring the imaging effect.
