[0002] Currently, a refrigerator is a common appliance for storing food and other items. It reduces the internal temperature through a refrigeration system to delay the spoilage and deterioration of food. For different food ingredients, since the suitable storage temperatures are different, it is necessary to adjust the refrigeration intensity inside the refrigerator, for example, by turning a knob or pressing a button. This results in a longer door opening time of the refrigerator, more leakage of cold air, and a reduced storage effect of the refrigerator.

[0003] In the related art, there is a refrigerator that includes a box body and a door body. The door body is rotatably connected to the box body, and a touch display screen is provided on the side wall of the door body. The user can adjust the operating parameters of the refrigerator by clicking on the touch display screen. Without opening and closing the door body, the operating parameters of the refrigerator can be changed, reducing the leakage of cold air, making the operation more convenient, improving the storage effect of the refrigerator, and enhancing the user experience.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] When directly touching the display screen, water stains and food residues are likely to remain on the display screen, which is prone to bacteria growth and results in a poor user experience.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of this application. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0020] Since a set angle is formed between the light beam emitted by the infrared sensor and the display surface of the display screen, and the negative refraction lens is located on the bisector of the set angle. The image displayed on the display screen is refracted by the negative refraction lens and then displayed into the assembly hole through the transparent member, thereby realizing aerial imaging. The imaging surface where the aerial image is located coincides with the light beam emitted by the infrared sensor. When the user clicks on the corresponding interface position on the imaging surface, the interface position of the object click is sensed and determined through the reflection of the light beam by the object, and then the operating parameters of the refrigeration device are correspondingly adjusted. This can prevent the user from directly touching the display screen, reduce the risk of water stains and food residues remaining on the display screen, reduce the growth of bacteria, and improve the user experience. Moreover, since the imaging surface is located within the assembly hole, the influence of external light sources on the aerial image can be reduced.

[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 1-2 As shown, the embodiments of the present disclosure provide a refrigeration device, including: a protection box 100, a transparent member 200, a negative refraction lens 300, a display screen 400, and an infrared sensor 500. An assembly hole 101 is provided on one side wall of the protection box 100; the transparent member 200 is arranged at the assembly hole 101; the negative refraction lens 300 is arranged in the protection box 100; the display screen 400 is arranged in the protection box 100; the infrared sensor 500 is embedded on the inner hole wall of the assembly hole 101, the infrared sensor 500 emits a light beam towards the assembly hole 101, the light beam is arranged parallel to the transparent member 200, and a set angle is formed between the light beam emitted by the infrared sensor 500 and the display surface of the display screen 400, and the negative refraction lens 300 is located on the angular bisector of the set angle.

[0042] Using the refrigeration device provided by the embodiments of the present disclosure, since a set angle is formed between the light beam emitted by the infrared sensor 500 and the display surface of the display screen 400, and the negative refraction lens 300 is located on the bisector of the set angle. The image displayed on the display screen 400 is refracted by the negative refraction lens 300 and then displayed into the assembly hole 101 through the transparent member 200, thereby realizing aerial imaging. The imaging surface 401 where the aerial image is located coincides with the light beam emitted by the infrared sensor 500. The user can click on the corresponding interface position on the imaging surface 401, and through the situation of the light beam being reflected by the object, sense and determine the interface position clicked by the object, and then correspondingly adjust the operating parameters of the refrigeration device. To avoid the user directly touching the display screen 400, reduce the risk of water stains and food residues remaining on the display screen 400, reduce the growth of bacteria, and improve the user experience. And the imaging surface 401 is located in the assembly hole 101, which can reduce the influence of external light sources on the aerial image.

[0043] Optionally, the protection box 100 is in a rectangular box structure. In this way, the shape of the protection box 100 is relatively regular and is adapted to the shape of the door body 700 of the refrigeration device, and it can be set at different positions on the door body 700 more flexibly.

[0044] Combined Figure 3 and Figure 4 As shown, optionally, a plug-in slot 102 is provided on the inner hole wall of the assembly hole 101, and the infrared sensor 500 is embedded in the plug-in slot 102. In this way, the infrared sensor 500 is arranged in the plug-in slot 102, and the plug-in slot 102 provides a limit for the infrared sensor 500, reducing the risk of the infrared sensor 500 shaking and displacing relative to the protection box 100. Ensure that the light beam emitted by the infrared sensor 500 coincides with the imaging surface 401 and ensure the accuracy of sensing.

[0045] Specifically, the plug-in slot 102 is located on the side of the transparent member 200 facing away from the negative refraction lens 300. In this way, when the infrared sensor 500 is repaired, there is no need to disassemble the transparent member 200, reducing the risk of dust entering the protection box 100 and ensuring the imaging effect.

[0046] It can be understood that since the infrared sensor 500 is embedded in the plug-in slot 102, the infrared sensor 500 is also located on the side of the transparent member 200 facing away from the negative refraction lens 300. Avoid the light beam emitted by the infrared sensor 500 coinciding with the transparent member 200.

[0047] Optionally, a part of the assembly hole 101 facing away from the negative refraction lens 300 is an outer layer hole, and a part of the assembly hole 101 facing the negative refraction lens 300 is an inner layer hole; the plug-in slot 102 and the infrared sensor 500 are located at the outer layer hole, and the transparent member 200 is located at the inner layer hole. In this way, avoid the light beam emitted by the infrared sensor 500 coinciding with the transparent member 200.

[0048] Optionally, the transparent member 200 is a transparent glass plate 210. In this way, the transparent glass plate 210 has good light transmittance, and the texture of the transparent glass plate 210 is relatively hard, reducing the risk of being scratched and ensuring the imaging effect.

[0049] Optionally, the area of the negative refraction lens 300 is larger than the area of the display surface of the display screen 400. In this way, due to the relatively large area of the negative refraction lens 300, the refraction range is relatively large, and the image displayed on the display screen 400 can be better refracted and displayed in the air, reducing the risk of incomplete display of the image in the air.

[0050] Optionally, the area of the transparent member 200 is larger than the area of the display surface of the display screen 400. In this way, the area of the transparent member 200 is relatively large, and the light transmission range is also relatively large, reducing the risk of incomplete display of the image in the air caused by the light of the negative refraction lens 300 being blocked.

[0051] Optionally, a first mounting bracket 110 is provided in the protection box 100, and a first mounting groove 111 is provided on the first mounting bracket 110, and the display screen 400 is embedded in the first mounting groove 111. In this way, the first mounting groove 111 on the first mounting bracket 110 provides support and limit for the display screen 400, reducing the risk of the display screen 400 shaking and displacing during the opening or closing process of the door body 700, thereby ensuring the imaging effect.

[0052] Optionally, the first mounting bracket 110 cooperates with the display screen 400 to divide the protection box 100 into a first chamber 103 and a second chamber 104, and the negative refraction lens 300 is located in the first chamber 103. In this way, by the cooperation of the first mounting bracket 110 and the display screen 400, the interior of the protection box 100 is divided into a first chamber 103 and a second chamber 104, improving the sealing performance between the display surface and the transparent member 200, reducing the risk of dust entering between the display surface and the negative refraction lens 300, and between the negative refraction lens 300 and the transparent member 200, and ensuring the imaging effect.

[0053] Specifically, the display surface of the display screen 400 faces the first chamber 103.

[0054] Optionally, the volume of the first chamber 103 is greater than or equal to 5 times the volume of the second chamber 104 and less than or equal to 7 times the volume of the first chamber 103. In this way, since the volume inside the protection box 100 remains unchanged, when the volume of the first chamber 103 is less than 5 times the volume of the second chamber 104, the volume inside the first chamber 103 is relatively small, and the sizes of the negative refractive lens 300 and the transparent member 200 are relatively small, resulting in a relatively high risk that the aerial image cannot be fully displayed. When the volume of the first chamber 103 is greater than 7 times the volume of the first chamber 103, the volume of the second chamber 104 is relatively small, leading to a relatively small heat dissipation space for the display screen 400 and a poor heat dissipation effect. Thus, it can be seen that the range where the volume of the first chamber 103 is greater than or equal to 5 times the volume of the second chamber 104 and less than or equal to 7 times the volume of the first chamber 103 is relatively reasonable, with a relatively low risk that the aerial image cannot be fully displayed and a relatively good heat dissipation effect for the display screen 400.

[0055] Optionally, the volume of the first chamber 103 is equal to 6 times the volume of the second chamber 104. In this way, the risk that the aerial image cannot be fully displayed is relatively low, and the heat dissipation effect of the display screen 400 is relatively good.

[0056] Optionally, a second mounting bracket 120 is provided inside the protection box 100, and a second mounting groove 121 is provided on the second mounting bracket 120. The negative refractive lens 300 is embedded in the second mounting groove 121. In this way, the second mounting groove 121 on the second mounting bracket 120 provides support and limitation for the negative refractive lens 300, reducing the risk of the negative refractive lens 300 shaking and displacing during the opening or closing process of the door body 700, thereby ensuring the imaging effect.

[0057] Optionally, the second mounting bracket 120 cooperates with the negative refractive lens 300 to divide the second chamber 104 into two independent chambers. In this way, the space between the display surface and the negative refractive lens 300 and the space between the negative refractive lens 300 and the transparent member 200 are not connected to each other. When one of the independent chambers is opened, the influence on the other independent chamber is reduced.

[0058] Optionally, the transparent member 200 is retracted into the assembly hole 101. In this way, since the imaging surface 401 is located inside the assembly hole 101 and the transparent member 200 is retracted into the assembly hole 101, the distance between the transparent member 200 and the imaging surface 401 can be set relatively large, reducing the risk of accidental touch of the transparent member 200 by the user. The risk of water stains and food residues remaining on the transparent member 200 is reduced, the growth of bacteria is reduced, and the user experience is improved.

[0059] Optionally, an inspection opening 105 is provided on one side wall of the protection box 100, and a cover plate 130 covering the inspection opening 105 is provided on one side of the protection box 100. In this way, it is convenient to inspect the display screen 400 inside the protection box 100 through the inspection opening 105.

[0060] Combined Figure 5 As shown, optionally, the cover plate 130 is provided with screw holes 131, and the cover plate 130 is fixed to the protection box 100 by screws passing through the screw holes 131. In this way, the cover plate 130 is fixed to the protection box 100 by screws, and the connection stability is higher, reducing the risk of the cover plate 130 falling off the protection box 100.

[0061] Optionally, there are multiple screw holes 131. In this way, the cover plate 130 is fixed to the protection box 100 by multiple screws respectively passing through a corresponding screw hole 131, and the connection stability is higher, reducing the risk of the cover plate 130 falling off the protection box 100.

[0062] Optionally, the maintenance port 105 is arranged on the adjacent side wall of the side wall of the protection box 100 where the assembly hole 101 is provided. In this way, when the maintenance port 105 and the assembly hole 101 are arranged on the same side wall, the area of the maintenance port 105 is relatively small and the maintenance difficulty is relatively large. Therefore, the maintenance port 105 is arranged on the adjacent side wall of the side wall of the protection box 100 where the assembly hole 101 is provided, and the area of the maintenance port 105 is relatively large, reducing the maintenance difficulty.

[0063] Specifically, the maintenance port 105 is arranged on the vertical side wall of the protection box 100.

[0064] Optionally, the cover plate 130 is arranged in parallel with the display screen 400. In this way, while ensuring the heat dissipation requirement of the display screen 400, the distance between the cover plate 130 and the display screen 400 can be set relatively small, thereby reducing the overall volume of the protection box 100. The smaller protection box 100 can be arranged on the door body 700 more flexibly, and the space occupied by the compartment of the refrigeration equipment is also relatively small.

[0065] Combined Figure 6 and Figure 7 As shown, optionally, a heat insulation layer 132 is fixedly arranged on the side wall of the cover plate 130 facing the maintenance port 105, and the heat insulation layer 132 extends into the maintenance port 105. In this way, the heat insulation effect of the cover plate 130 is increased through the heat insulation layer 132, reducing the conduction of low temperature in the refrigeration equipment compartment into the protection box 100, and also improving the sealing effect between the cover plate 130 and the maintenance port 105.

[0066] Optionally, the maintenance port 105 is arranged on the opposite side of the display surface of the display screen 400. In this way, the opposite side of the display surface of the display screen 400 is the back surface of the display screen 400. Since there are relatively more parts on the back surface of the display screen 400, the maintenance of the display screen 400 is relatively more convenient.

[0067] Optionally, the access opening 105 communicates with the second chamber 104. In this way, after the cover plate 130 is opened, the display screen 400 in the second chamber 104 can be repaired, reducing the impact on the first chamber 103 and lowering the risk of dust entering the first chamber 103 during the repair process, thus ensuring the imaging effect.

[0068] Optionally, a control board 600 is provided on the side of the display screen 400 facing the access opening 105. The control board 600 is electrically connected to the display screen 400 and the infrared sensor 500. In this way, the infrared sensor 500 sends the sensed signal to the control board 600, and the control board 600 correspondingly adjusts the operating parameters of the refrigeration equipment to improve the user experience.

[0069] Optionally, the control board 600 is connected to the display screen 400 through a connecting bracket 610. In this way, the control board 600 and the display screen 400 are connected through the connecting bracket 610, increasing the distance between the display screen 400 and the control board 600 and improving the heat dissipation effect of the control board 600.

[0070] Specifically, the control board 600 is arranged in parallel with the display screen 400.

[0071] Specifically, the control board 600 is arranged in the second chamber 104, and the control board 600 is located between the cover plate 130 and the display screen 400. In this way, after the cover plate 130 is opened, it is more convenient to repair the control board 600 in the second chamber 104, reducing the impact on the first chamber 103 and lowering the risk of dust entering the first chamber 103 during the repair process, thus ensuring the imaging effect.

[0072] Optionally, a first included angle 106 is provided between the display surface of the display screen 400 and the negative refraction lens 300; a second included angle 107 is provided between the light beam emitted by the infrared sensor 500 and the negative refraction lens 300; wherein, the first included angle 106 and the second included angle 107 are equal, and the first included angle 106 is greater than or equal to 30° and less than or equal to 60°. In this way, the first included angle 106 and the second included angle 107 are equal, making the light beam emitted by the infrared sensor 500 coincide with the imaging surface 401 and improving the operation accuracy. When the first included angle 106 is less than 30°, the included angle between the display screen 400 and the negative refraction lens 300 is too small, and there is a greater risk of double imaging on the imaging surface 401. When the first included angle 106 is greater than 60°, the maximum distance between the display screen 400 and the negative refraction lens 300 is too large, making the volume of the protection box 100 relatively large and occupying too much space in the refrigeration equipment room. It can be seen that the range of the first included angle 106 being greater than or equal to 30° and less than or equal to 60° is more reasonable, reducing the risk of double imaging on the imaging surface 401 and reducing the space occupied in the refrigeration equipment room.

[0073] It can be understood that the maximum distance is the distance between one end of the display screen 400 facing away from the negative refraction lens 300 and one end of the negative refraction lens 300 facing away from the display screen 400.

[0074] Optionally, the first included angle 106 is equal to 45°. In this way, the risk of double images appearing on the imaging surface 401 is reduced, and the space occupied in the refrigeration equipment room is decreased.

[0075] Specifically, a third included angle 108 is provided between the transparent member 200 and the negative refraction lens 300, and the third included angle 108 is equal to the first included angle 106.

[0076] Optionally, a wire harness hole 109 is provided on one side wall of the protection box 100. In this way, through the wire harness hole 109, it is convenient to electrically connect the display screen 400 and the infrared sensor 500 in the protection box 100 to other components of the refrigeration equipment. For example, electrically connect to the power supply of the refrigeration equipment.

[0077] Optionally, the wire harness hole 109 communicates with the second chamber 104. In this way, it is avoided that the wire harness laid in the first chamber 103 affects the imaging effect.

[0078] Optionally, the wire harness hole 109 is provided on the adjacent side wall of the side wall of the protection box 100 where the assembly hole 101 is provided. In this way, when the protection box 100 is assembled on the door body 700, for the convenience of user operation, the assembly hole 101 faces the front side wall of the door body 700. And the wire harness hole 109 is located on the adjacent side wall of the side wall of the protection box 100 where the assembly hole 101 is provided, which is convenient for the wire harness to be laid in the foaming layer of the door body 700 and reduces the risk of wire harness exposure.

[0079] Specifically, the wire harness hole 109 is provided on the horizontal side wall of the protection box 100.

[0080] Combined Figure 8 and Figure 9 As shown, optionally, the refrigeration equipment further includes: a door body 700. A through hole 701 is provided on the door body 700, and the assembly hole 101 of the protection box 100 is embedded in the door body 700 corresponding to the through hole 701. In this way, the through hole 701 and the assembly hole 101 communicate correspondingly, which is convenient for the user to click on the imaging surface 401.

[0081] Optionally, the projected area of the through hole 701 facing the transparent member 200 is smaller than the area of the transparent member 200. In this way, the transparent member 200 is relatively large, reducing the risk of the transparent member 200 falling out from the through hole 701.

[0082] Specifically, the projection of the through hole 701 facing the transparent member 200 is located at the middle position of the transparent member 200. In this way, it is convenient for the user to observe the phenomenon surface, and it is avoided that the imaging surface 401 is biased towards one side of the through hole 701, which is convenient for the user to click on the imaging surface 401 and improves the user experience.

[0083] Combined with Figure 10 As shown, optionally, a limiting groove 710 is provided on the inner rear wall of the door body 700, and a part of the protection box 100 is located in the limiting groove 710. In this way, the limiting groove 710 can provide limitation and support for the protection box 100, reduce the risk of the protection box 100 shaking and displacing relative to the door body 700, and ensure the imaging effect.
