[0040] The term "and / or" describes the association relationship of objects, indicating that there can be three relationships. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0041] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0042] Combined with Figure 1-2 As shown, the embodiments of the present disclosure provide a contactless control module for a refrigerator, including: a protection box 100, an imaging module 200, and a heating component 300. An assembly hole 101 is provided on the first side wall 110 of the protection box 100; the imaging module 200 is disposed in the protection box 100, and part of it is located in the assembly hole 101; the heating component 300 is disposed on the side wall of the protection box 100.

[0043] By using the contactless control module for a refrigerator provided by the embodiments of the present disclosure, since the heating component 300 is provided in the protection box 100, when the temperature in the protection box 100 is relatively low, the heating component 300 heats up to increase the temperature in the protection box 100, avoiding the temperature of the imaging module 200 from being too low. To reduce the risk of condensation inside the imaging module 200 during long-term use and improve the imaging effect.

[0044] Optionally, the protection box 100 is a rectangular box-shaped structure. In this way, the shape of the protection box 100 is relatively regular and is adapted to the shape of the refrigerator door body 400, and it can be more flexibly set at different positions on the door body 400.

[0045] Combined with Figure 3 As shown, optionally, the heating component 300 includes: a heating wire 310 and a temperature sensor 320. The heating wire 310 is disposed on the inner side wall of the protection box 100; the temperature sensor 320 is disposed in the protection box 100. In this way, the temperature in the protection box 100 is measured by the temperature sensor 320. When the temperature in the protection box 100 is relatively low, the heating wire 310 heats up to increase the temperature in the protection box 100, reducing the risk of condensation inside the imaging module 200 and improving the imaging effect.

[0046] Optionally, a heat insulation layer 120 is provided on the inner side wall and / or the outer side wall of the protection box 100. And when the heat insulation layer 120 is provided on the inner side wall of the protection box 100, an avoidance hole 121 is provided at the position corresponding to the heating component 300 on the heat insulation layer 120. In this way, during the heating process of the heating component 300, due to the existence of the avoidance hole 121, the risk of deformation of the heat insulation layer 120 caused by too high temperature is reduced. And the heat insulation layer 120 reduces the conduction of external low temperature towards the inside of the protection box 100.

[0047] Specifically, the heat insulation layer 120 is made of foam material.

[0048] Specifically, an avoidance hole 121 is provided at the position of the heat insulation layer 120 corresponding to the heating wire 310. In this way, during the heating process of the heating wire 310, due to the existence of the avoidance hole 121, the risk of deformation of the heat insulation layer 120 caused by excessive temperature is reduced.

[0049] Optionally, heat insulation layers 120 are provided on both the adjacent and opposite vertical side walls of the first side wall 110 of the protection box 100. In this way, the heat insulation layer 120 reduces the conduction of external low temperature towards the inside of the protection box 100.

[0050] Optionally, a transparent member 130 is provided in the assembly hole 101, and the transparent member 130 is embedded in the hole wall of the assembly hole 101. In this way, the transparent member 130 provides protection for the imaging module 200 inside the protection box 100, reducing the risk of the imaging module 200 being damaged by knocking and bumping, and also reducing the risk of dust entering the protection box 100 and affecting the imaging effect.

[0051] Optionally, the transparent member 130 is a transparent glass plate 131. In this way, the transparent glass plate 131 has good light transmittance, and the texture of the transparent glass plate 131 is relatively hard, reducing the risk of being scratched and ensuring the imaging effect.

[0052] Optionally, the transparent member 130 retracts into the assembly hole 101 towards the protection box 100. In this way, the distance between the transparent member 130 and the outer side surface of the first side wall 110 is relatively large, reducing the risk of the transparent member 130 being damaged by knocking and bumping.

[0053] Combined Figure 4As shown, optionally, the imaging module 200 includes a negative refraction lens 210, a display screen 220, and an infrared sensor 230. The negative refraction lens 210 is disposed within the protective box 100; the display screen 220 is disposed within the protective box 100; the infrared sensor 230 is embedded in the hole wall of the assembly hole 101. The infrared sensor 230 emits a light beam towards the inside of the assembly hole 101, and the light beam is arranged parallel to the first side wall 110. A set angle is formed between the light beam emitted by the infrared sensor 230 and the display surface of the display screen 220, and the negative refraction lens 210 is located on the angular bisector of the set angle. In this way, since a set angle is formed between the light beam emitted by the infrared sensor 230 and the display surface of the display screen 220, and the negative refraction lens 210 is located on the angular bisector of the set angle. The image displayed on the display screen 220 is refracted by the negative refraction lens 210 and displayed into the assembly hole 101 through the transparent member 130, thereby realizing aerial imaging. The imaging surface 221 where the aerial image is located coincides with the light beam emitted by the infrared sensor 230. The user can click on the corresponding interface position on the imaging surface 221, and sense and determine the interface position clicked by the object through the reflection of the light beam by the object, and then correspondingly adjust the operating parameters of the refrigerator. This avoids the user directly touching the display screen 220, reduces the risk of water stains and food residues remaining on the display screen 220, reduces the growth of bacteria, and improves the user experience.

[0054] It can be understood that since the imaging surface 221 is located within the assembly hole 101 and the transparent member 130 is retracted into the assembly hole 101, the distance between the transparent member 130 and the imaging surface 221 can be set relatively large, reducing the risk of the user accidentally touching the transparent member 130. Reducing the risk of water stains and food residues remaining on the transparent member 130 improves the user experience.

[0055] Optionally, a first angle 201 is provided between the display surface of the display screen 220 and the negative refraction lens 210; a second angle 202 is provided between the light beam emitted by the infrared sensor 230 and the negative refraction lens 210; wherein, the first angle 201 and the second angle 202 are equal, and the first angle 201 is greater than or equal to 30° and less than or equal to 60°. In this way, the equality of the first angle 201 and the second angle 202 makes the light beam emitted by the infrared sensor 230 coincide with the imaging surface 221, improving the accuracy of operation. When the first angle 201 is less than 30°, the angle between the display screen 220 and the negative refraction lens 210 is too small, and there is a greater risk of ghosting on the imaging surface 221. When the first angle 201 is greater than 60°, the maximum distance between the display screen 220 and the negative refraction lens 210 is too large, making the volume of the protective box 100 relatively large, occupying too much space in the refrigerator compartment. It can be seen that the range of the first angle 201 being greater than or equal to 30° and less than or equal to 60° is more reasonable, reducing the risk of ghosting on the imaging surface 221 and reducing the space occupied in the refrigerator compartment.

[0056] It can be understood that the maximum distance is the distance between one end of the display screen 220 facing away from the negative refraction lens 210 and one end of the negative refraction lens 210 facing away from the display screen 220.

[0057] Optionally, the first included angle 201 is equal to 45°. In this way, the risk of double images appearing on the imaging surface 221 is reduced, and the space occupied in the refrigerator compartment is reduced.

[0058] Specifically, a third included angle 203 is provided between the transparent member 130 and the negative refraction lens 210, and the third included angle 203 is equal to the first included angle 201.

[0059] Combined Figure 4 and Figure 5 As shown, optionally, a plug-in groove 102 is provided on the inner hole wall of the assembly hole 101, and the infrared sensor 230 is embedded in the plug-in groove 102. In this way, the infrared sensor 230 is arranged in the plug-in groove 102, and the plug-in groove 102 provides a limit for the infrared sensor 230, reducing the risk of the infrared sensor 230 shaking and displacing relative to the protection box 100. Ensure that the light beam emitted by the infrared sensor 230 coincides with the imaging surface 221, ensuring the accuracy of induction.

[0060] Specifically, the plug-in groove 102 is located on the side of the transparent member 130 facing away from the negative refraction lens 210. In this way, when the infrared sensor 230 is repaired, it is not necessary to disassemble the transparent member 130, reducing the risk of dust entering the protection box 100 and ensuring the imaging effect.

[0061] It can be understood that since the infrared sensor 230 is embedded in the plug-in groove 102, the infrared sensor 230 is also located on the side of the transparent member 130 facing away from the negative refraction lens 210. Avoid the light beam emitted by the infrared sensor 230 from coinciding with the transparent member 130.

[0062] Optionally, a part of the assembly hole 101 facing away from the negative refraction lens 210 is an outer layer hole, and a part of the assembly hole 101 facing the negative refraction lens 210 is an inner layer hole; the plug-in groove 102 and the infrared sensor 230 are located at the outer layer hole, and the transparent member 130 is located at the inner layer hole. In this way, avoid the light beam emitted by the infrared sensor 230 from coinciding with the transparent member 130.

[0063] Optionally, the area of the negative refraction lens 210 is larger than the area of the display surface of the display screen 220. In this way, since the area of the negative refraction lens 210 is relatively large, the refraction range is relatively large, and the image displayed on the display surface can be refracted and displayed in the air better, reducing the risk of incomplete display of the image in the air.

[0064] Optionally, a first mounting bracket 140 is provided inside the protection box 100. The display screen 220 is embedded in the first mounting bracket 140, and the display screen 220 cooperates with the first mounting bracket 140 to divide the protection box 100 into a first chamber 103 and a second chamber 104. The negative refraction lens 210 is located in the first chamber 103. In this way, through the cooperation of the first mounting bracket 140 and the display screen 220, the inside of the protection box 100 is divided into the first chamber 103 and the second chamber 104, improving the sealing performance between the display surface and the transparent member 130, reducing the risk of dust entering between the display surface and the negative refraction lens 210, and between the negative refraction lens 210 and the transparent member 130, and ensuring the imaging effect.

[0065] Optionally, a first mounting groove 141 for embedding the display screen 220 is provided on the first mounting bracket 140. In this way, the first mounting groove 141 on the first mounting bracket 140 provides support and limit for the display screen 220, reducing the risk of the display screen 220 shaking and displacing during the opening or closing of the door body 400, thereby ensuring the imaging effect.

[0066] Specifically, the display surface of the display screen 220 faces the first chamber 103.

[0067] Optionally, a second mounting bracket 150 is provided inside the protection box 100. A second mounting groove 151 is provided on the second mounting bracket 150. The negative refraction lens 210 is embedded in the second mounting groove 151. In this way, the second mounting groove 151 on the second mounting bracket 150 provides support and limit for the negative refraction lens 210, reducing the risk of the negative refraction lens 210 shaking and displacing during the opening or closing of the door body 400, thereby ensuring the imaging effect.

[0068] Optionally, the second mounting bracket 150 cooperates with the negative refraction lens 210 to divide the second chamber 104 into two independent chambers. In this way, the space between the display surface and the negative refraction lens 210 and the space between the negative refraction lens 210 and the transparent member 130 are not connected to each other. When one of the independent chambers is opened, the influence on the other independent chamber is reduced.

[0069] Optionally, there are multiple heating wires 310, and heating wires 310 are provided in both the first chamber 103 and the second chamber 104. In this way, multiple heating wires 310 heat simultaneously, making the temperature increase in the first chamber 103 and the second chamber 104 more uniform and reducing the temperature difference.

[0070] Specifically, there are three heating wires 310, two of which are provided in the second chamber 104, and the two heating wires 310 in the second chamber 104 are respectively arranged in two independent chambers.

[0071] Combined with Figure 6As shown, optionally, a control board 240 is provided on one side of the display screen 220. The control board 240 is electrically connected to the display screen 220 and the infrared sensor 230. In this way, the infrared sensor 230 sends the sensed signal to the control board 240, and the control board 240 correspondingly adjusts the operating parameters of the refrigerator to improve the user experience.

[0072] Optionally, the control board 240 is connected to the display screen 220 through a connecting bracket 250. In this way, the control board 240 and the display screen 220 are connected through the connecting bracket 250, increasing the distance between the display screen 220 and the control board 240 and improving the heat dissipation effect of the control board 240.

[0073] Combined Figure 7 As shown, optionally, an access opening 105 is provided on one side of the protection box 100, and a cover plate 160 covering the access opening 105 is provided on one side. In this way, it is convenient to repair the display screen 220 in the protection box 100 through the access opening 105.

[0074] Optionally, screw holes 161 are provided on the cover plate 160, and the cover plate 160 is fixed to the protection box 100 by screws passing through the screw holes 161. In this way, the cover plate 160 is fixed to the protection box 100 by screws, with higher connection stability and reducing the risk of the cover plate 160 falling off the protection box 100.

[0075] Specifically, the heating wire 310 in the second chamber 104 is arranged on the side wall of the cover plate 160 facing the protection box 100.

[0076] Optionally, a heat insulation layer 120 is provided on the side wall of the cover plate 160 facing the protection box 100. In this way, the heat insulation effect of the cover plate 160 is increased through the heat insulation layer 120, reducing the conduction of low temperature in the refrigerator compartment into the protection box 100.

[0077] Optionally, the access opening 105 is provided on the adjacent side wall of the first side wall 110 of the protection box 100. In this way, when both the access opening 105 and the assembly hole 101 are provided on the first side wall 110, the area of the access opening 105 is relatively small and the repair difficulty is relatively large. Therefore, the access opening 105 is provided on the adjacent side wall of the first side wall 110 of the protection box 100, and the area of the access opening 105 is relatively large, reducing the repair difficulty.

[0078] Specifically, the access opening 105 is provided on the vertical side wall of the protection box 100.

[0079] Optionally, the cover plate 160 is arranged parallel to the display screen 220. In this way, while ensuring the heat dissipation requirements of the display screen 220, the distance between the cover plate 160 and the display screen 220 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 400 more flexibly, and the space occupied by the compartments of the refrigerator is also relatively small.

[0080] Optionally, the maintenance opening 105 is communicated with the second chamber 104. In this way, after the cover plate 160 is opened, the display screen 220 in the second chamber 104 can be maintained, reducing the influence on the first chamber 103, reducing the risk of dust entering the first chamber 103 during the maintenance process, and ensuring the imaging effect.

[0081] Specifically, the control board 240 is arranged in the second chamber 104, and the control board 240 is located between the cover plate 160 and the display screen 220. In this way, after the cover plate 160 is opened, it is more convenient to maintain the control board 240 in the second chamber 104, reducing the influence on the first chamber 103, reducing the risk of dust entering the first chamber 103 during the maintenance process, and ensuring the imaging effect.

[0082] Optionally, a wire harness hole 106 is provided on one side wall of the protection box 100. In this way, through the wire harness hole 106, it is convenient to electrically connect the display screen 220 and the infrared sensor 230 in the protection box 100 to other components of the refrigerator. For example, electrically connect to the power supply of the refrigerator.

[0083] Optionally, the wire harness hole 106 is communicated 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.

[0084] In some embodiments, the refrigerator includes: a contactless control module for the refrigerator according to any one of the above embodiments.

[0085] For the refrigerator provided by the embodiments of the present disclosure, since the refrigerator includes a contactless control module for the refrigerator according to any one of the above embodiments, and since a heating component 300 is provided in the protection box 100, when the temperature in the protection box 100 is relatively low, the heating component 300 heats up to increase the temperature in the protection box 100, avoiding the temperature of the imaging module 200 from being too low during operation. To reduce the risk of condensation inside the imaging module 200 during long-term use and improve the imaging effect.

[0086] Combined with Figure 8 As shown, optionally, the refrigerator further includes: a door body 400. A through hole 401 is provided on the front side wall of the door body 400, and the assembly hole 101 of the protection box 100 is embedded in the door body 400 corresponding to the through hole 401. In this way, the through hole 401 and the assembly hole 101 are correspondingly communicated, facilitating the user to click on the imaging surface 221.

[0087] Optionally, the projected area of the through hole 401 towards the transparent member 130 is smaller than the area of the transparent member 130. In this way, the transparent member 130 is relatively large, reducing the risk of the transparent member 130 falling out of the through hole 401.
