Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a door assembly and a refrigerator. Background Art

[0002] Currently, refrigerators can maintain relatively low temperatures for storing items, extending their shelf life. Some refrigerators also feature touchscreens on the door to adjust the temperature or humidity inside the refrigerator compartment. This allows for adjustments to operating parameters based on the characteristics of the ingredients. However, these touchscreens can become stained and harbor bacteria over time, resulting in a poor user experience.

[0003] A related art refrigerator has an aerial imaging module installed on the door. This module generates an image in the air in front of the door and controls the image to adjust the refrigerator's operating parameters. This allows the refrigerator's operating parameters to be adjusted without direct contact with the door, preventing stains on the door and reducing bacterial growth, thereby improving the user experience.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] During long-term operation, frost is likely to form inside the aerial imaging module, affecting the aerial imaging effect.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0039] Unless otherwise stated, the term "plurality" means two or more.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0041] Combine Figure 1-3 As shown, an embodiment of the present disclosure provides a door assembly, comprising: a door 100, an imaging module 200, and a thermal insulation member 300. A through hole 101 is provided on the front sidewall of the door 100; the imaging module 200 is embedded in the door 100 at a location corresponding to the through hole 101, and the rear side of the imaging module 200 extends through the rear sidewall of the door 100 toward the rear side of the door 100; the thermal insulation member 300 covers the side of the imaging module 200 that extends through the door 100.

[0042] With the door assembly provided by the embodiments of the present disclosure, the imaging module 200 is embedded in the door 100 at the corresponding through-hole 101, and the rear side of the imaging module 200 extends through the rear wall of the door 100 toward the rear side of the door 100. Furthermore, the thermal insulation member 300 covers the side of the imaging module 200 extending through the door 100. The thermal insulation member 300 is further disposed between the refrigerator compartment and the imaging module 200. The thermal insulation member 300 blocks temperature transfer between the compartment and the imaging module 200, reducing the impact of low temperatures within the compartment on the imaging module 200. This reduces the risk of frost condensation inside the aerial imaging module 200, ensures the quality of aerial imaging, and enhances the user experience.

[0043] Combine Figure 4 As shown, a transparent protective plate 110 is optionally provided within the through-hole 101. Thus, the transparent protective plate 110 protects the imaging module 200, reducing the risk of knocks and impacts. The transparent protective plate 110 also seals the through-hole 101, reducing the risk of dust entering the door 100 and the imaging module 200, thereby ensuring the imaging effect of the imaging module 200.

[0044] Optionally, the transparent protective plate 110 is a transparent glass plate 111. In this way, the transparent glass plate 111 has good light transmittance, ensuring the imaging effect of the imaging module 200. In addition, the transparent glass plate 111 is relatively hard, reducing the risk of being scratched.

[0045] Optionally, the insulation component 300 includes a module support 310 and a first module insulation layer 320. The module support 310 covers the imaging module 200; the first module insulation layer 320 is disposed between the module support 310 and the imaging module 200. This arrangement, with the module support 310 covering the imaging module 200 and the first module insulation layer 320 disposed between the module support 310 and the imaging module 200, reduces the rate at which low temperatures within the refrigerator compartment are transferred to the imaging module 200, minimizing the impact on the imaging module 200. This also reduces the risk of frost forming inside the aerial imaging module 200, ensuring effective aerial imaging and enhancing the user experience.

[0046] Specifically, the first module heat-insulating layer 320 is made of foam material, so that the heat-insulating performance is relatively good, and the speed at which the low temperature in the refrigerator compartment is transferred toward the imaging module 200 is reduced.

[0047] Optionally, the end of the module bracket 310 facing the imaging module 200 extends into the door body 100 and covers the imaging module 200. In this way, the module bracket 310 extends into the door body 100, and the door body 100 provides a position limit for the module bracket 310, reducing the risk of the module bracket 310 shaking. The module bracket 310 also covers a relatively large area of the imaging module 200, improving the thermal insulation effect.

[0048] Optionally, the insulation member 300 further includes a module insulation cover 330 and a second module insulation layer 340. The module insulation cover 330 is disposed over the module support 310; the second module insulation layer 340 is located between the module insulation cover 330 and the module support 310. This further improves the thermal insulation effect on the imaging module 200 through the module insulation cover 330 and the second module insulation layer 340, the module support 310, and the first module insulation layer 320, thereby reducing the speed at which low temperatures within the refrigerator compartment are transferred to the imaging module 200, thereby minimizing the impact on the imaging module 200.

[0049] Specifically, the second module heat-insulating layer 340 is made of foam material, so that the heat-insulating performance is relatively good, and the speed at which the low temperature in the refrigerator compartment is transferred toward the imaging module 200 is reduced.

[0050] Optionally, the second module insulation layer 340 extends toward the front sidewall of the door body 100 and into the interior of the door body 100. This allows the second module insulation layer 340 to cover a wider area and provide better insulation. Furthermore, the door body 100 can provide a position limit for the second module insulation layer 340, reducing the risk of the second module insulation layer 340 shaking.

[0051] Optionally, the module heat preservation cover 330 abuts against the rear side wall of the door body 100. In this way, the module heat preservation cover 330 abuts against the rear side wall of the door body 100, which has a better sealing effect, reduces the risk of low-temperature gas entering the module heat preservation cover 330, and reduces the impact of the low temperature inside the compartment on the imaging module 200.

[0052] Optionally, the first module thermal insulation layer 320 is located on opposite sides of the imaging module 200, and the second module thermal insulation layer 340 is located on the side of the module bracket 310 facing away from the door body 100; or, the first module thermal insulation layer 320 is located on the side of the imaging module 200 facing away from the door body 100, and the second module thermal insulation layer 340 is located on opposite sides of the module bracket 310. In this way, the first module thermal insulation layer 320 and the second module thermal insulation layer 340 cooperate to more comprehensively block low temperatures from being transmitted to the imaging module 200, and the required material cost is relatively low.

[0053] Combine Figure 5 As shown, the imaging module 200 optionally includes: a protective box 210, a negative refractive lens 220, a display screen 230, and an infrared sensor 240. The protective box 210 has a mounting hole 211 on the side facing the front wall of the door body 100, which corresponds to the position of the through hole 101. The negative refractive lens 220 is disposed within the mounting hole 211. The display screen 230 is disposed within the protective box 210. The infrared sensor 240 is disposed within the protective box 210, located on one side of the mounting hole 211. The light beam emitted by the infrared sensor 240 forms a predetermined angle with the display surface of the display screen 230, and the negative refractive lens 220 is located on the bisector of the predetermined angle. Thus, the image displayed on the display surface of the display screen 230 is refracted by the negative refractive lens 220 into the air in front of the door body 100, forming the imaging surface 201. The light beam emitted by infrared sensor 240 overlaps with display surface 201. The user can drive an object to display surface 201 and click the corresponding interface position on display surface 201. The reflection of the light beam by the object can sense and determine the interface position where the object clicked, and then adjust the operating parameters of the refrigerator accordingly. This prevents the user from directly contacting display screen 230, reduces residual water stains and food residues on the refrigerator, and improves the user experience. The protective box 210 provides support and fixation for the negative refractive lens 220, display screen 230, and infrared sensor 240, reducing the risk of relative displacement of the negative refractive lens 220, display screen 230, and infrared sensor 240.

[0054] Optionally, a first angle 202 is defined between the display surface of display screen 230 and negative refractive lens 220; a second angle 203 is defined between the light beam emitted by infrared sensor 240 and negative refractive lens 220. The first angle 202 and the second angle 203 are equal, and the first angle 202 is greater than or equal to 35° and less than or equal to 55°. Thus, the equality of first angle 202 and second angle 203 allows the light beam emitted by infrared sensor 240 to coincide with the image display surface 201, improving operational accuracy. If the first angle 202 is less than 35°, the distance between display screen 230 and negative refractive lens 220 is too close, placing the image display surface 201 too close to door 100, and increasing the risk of a user accidentally touching door 100. If the first angle 202 is greater than 55°, the angle between the image display surface and the horizontal plane is too small, affecting the user's viewing experience of the image display surface. It can be seen that the range of the first angle 202 being greater than or equal to 35° and less than or equal to 55° is relatively reasonable, which reduces the risk of the user accidentally touching the door body 100 and also facilitates the user to observe the display surface 201.

[0055] Optionally, the first angle 202 is equal to 45°. In this way, the risk of the user accidentally touching the door body 100 is lowered, and it is also convenient for the user to observe the display surface 201.

[0056] Optionally, a first mounting bracket 212 is provided within the protective box 210, and a first mounting slot 213 is provided on the first mounting bracket 212 for mounting the display screen 230. The first mounting bracket 212 cooperates with the display screen 230 to separate the interior of the protective box 210 into a first chamber 204 and a second chamber 205. Thus, the first mounting slot 213 on the first mounting bracket 212 provides support and position limiting for the display screen 230, reducing the risk of the display screen 230 shaking and shifting during the opening or closing of the door 100. Furthermore, the interior of the protective box 210 is divided into the first chamber 204 and the second chamber 205, improving the seal between the display screen 230 and the negative refractive lens 220, reducing the risk of dust entering between the display screen 230 and the negative refractive lens 220, and ensuring the imaging effect.

[0057] Specifically, the first mounting bracket 212 is fixedly connected to the inner wall of the protection box 210 .

[0058] Specifically, the first cavity 204 is communicated with the mounting hole 211 , and the display surface of the display screen 230 faces the first cavity 204 .

[0059] Optionally, a control board 250 is provided in the protective box 210. The control board 250 is electrically connected to the display screen 230 and the infrared sensor 240, and the control board 250 is located in the second chamber 205. In this way, the infrared sensor 240 sends a sensed signal to the control board 250, which then adjusts the operating parameters of the refrigerator accordingly, thereby improving the user experience.

[0060] Optionally, the control board 250 is connected to the display screen 230 via a connecting bracket 260. In this way, the control board 250 and the display screen 230 are connected via the connecting bracket 260, the distance between the display screen 230 and the control board 250 is increased, and the heat dissipation effect is better.

[0061] Specifically, the control panel 250 is connected to the other side of the display screen 230 opposite to the display surface.

[0062] Combine Figure 6 As shown, optionally, a plug-in slot 214 is provided within the protective case 210, and an infrared sensor 240 is disposed within the plug-in slot 214. A beam hole 215 is provided on the front sidewall of the protective case 210, corresponding to the infrared sensor 240. The beam hole 215 communicates with the plug-in slot 214. This secures the infrared sensor 240 within the plug-in slot 214, reducing the risk of displacement and shaking. The light beam emitted by the infrared sensor 240 passes through the beam hole 215 and coincides with the imaging surface 201.

[0063] Optionally, the length of the beam hole 215 in the horizontal direction is smaller than the length of the infrared sensor 240. In this way, the risk of the infrared sensor 240 falling from the beam hole 215 is reduced.

[0064] Specifically, the insertion slot 214 is communicated with the second chamber 205 .

[0065] Combine Figure 6 and Figure 7 As shown, optionally, an inspection port 216 is provided on the rear side wall of the protective box 210 corresponding to the display screen 230, and a cover plate 217 is provided on one side of the protective box 210 to cover the inspection port 216. In this way, the control board 250, the display screen 230, and the infrared sensor 240 in the protective box 210 can be easily inspected through the inspection port 216.

[0066] Optionally, the inspection port 216 is connected to the second chamber 205 and faces the back of the display screen 230. In this way, after the cover 217 is opened, the control board 250, display screen 230, and infrared sensor 240 in the second chamber 205 can be inspected and maintained, which reduces the impact on the first chamber 204 and the risk of dust entering the first chamber 204 during the inspection process, thereby ensuring the imaging effect.

[0067] Combine Figure 8 As shown, optionally, a wiring harness hole 218 is provided on the protection box 210. In this way, the display screen 230 and the infrared sensor 240 in the protection box 210 can be conveniently electrically connected to other components of the refrigerator through the wiring harness hole 218. For example, they can be electrically connected to the power supply of the refrigerator.

[0068] Specifically, the harness hole 218 is in communication with the second chamber 205. In this way, the harness arranged in the first chamber 204 is prevented from affecting the imaging effect.

[0069] Optionally, the harness hole 218 is provided on the side wall of the protective box 210 adjacent to the side wall provided with the mounting hole 211. In this way, since the mounting hole 211 is provided toward the front side wall of the door body 100, and the harness hole 218 is located on the side wall of the protective box 210 adjacent to the side wall provided with the mounting hole 211, it is convenient to route the harness in the foam layer of the door body 100, reducing the risk of the harness being exposed.

[0070] Specifically, the harness hole 218 is provided on a vertical side wall of the protection box 210 .

[0071] Optionally, when the first module thermal insulation layer 320 is located on opposite sides of the imaging module 200 and the second module thermal insulation layer 340 is located on the side of the module bracket 310 facing away from the door body 100, a first avoidance hole 321 is provided on the first module thermal insulation layer 320 at a location corresponding to the harness hole 218, and a second avoidance hole 311 is provided on the module bracket 310 at a location corresponding to the harness hole 218. In this way, the first avoidance hole 321 prevents the first module thermal insulation layer 320 from interfering with the wiring of the harness, and the second avoidance hole 311 prevents the module bracket 310 from interfering with the wiring of the harness.

[0072] Combine Figure 9 and Figure 10 As shown, optionally, a mounting groove 102 is provided on the rear sidewall of the door 100. The mounting groove 102 communicates with the through hole 101, and the imaging module 200 is inserted into the mounting groove 102. Thus, the mounting groove 102 provides a position limit and support for the imaging module 200, reducing the risk of the imaging module 200 shaking. Furthermore, the mounting groove 102 reduces the height of the imaging module 200 protruding from the door 100, thereby reducing the encroachment on the interior space of the refrigerator compartment.

[0073] Specifically, the protective box 210 is embedded in the mounting groove 102. Thus, the mounting groove 102 provides a position limit and support for the protective box 210, reducing the risk of the protective box 210 shaking. Furthermore, the protective box 210 is embedded in the mounting groove 102, which reduces the height of the protective box 210 protruding from the door 100 and reduces the encroachment on the interior space of the refrigerator compartment.

[0074] Optionally, the module bracket 310 extends into the assembly slot 102 and covers the imaging module 200. In this way, the assembly slot 102 provides a limit and support for the module bracket 310, reduces the risk of the module bracket 310 shaking, and reduces the height of the module bracket 310 protruding from the door body 100.

[0075] Optionally, a snap-fit groove 103 is provided at the groove edge of the assembly groove 102, and the end of the module heat-insulating cover 330 facing the module bracket 310 is covered in the snap-fit groove 103. In this way, the sealing between the module heat-insulating cover 330 and the door body 100 is improved, the risk of low-temperature gas entering the module heat-insulating cover 330 is reduced, the heat insulation effect is improved, and the connection stability is higher.

[0076] Optionally, a flange 331 is provided on the outer periphery of the module thermal insulation cover 330 at the end facing the module support 310. The flange 331 is engaged with the engaging groove 103, and the end of the module thermal insulation cover 330 facing the module support 310 extends into the assembly groove 102. This increases the contact area between the flange 331 and the engaging groove 103, improving sealing. The extension of one end of the module thermal insulation cover 330 into the assembly groove 102 enhances the stability of the connection.

[0077] Optionally, the module heat preservation cover 330 is engaged with the inner groove wall of the assembly groove 102 by a snap fastener 400. In this way, the strength of the connection between the module heat preservation cover 330 and the assembly groove 102 is higher, reducing the risk of the module heat preservation cover 330 falling off from the assembly groove 102.

[0078] Specifically, there are multiple fasteners 400 .

[0079] Optionally, the fastener 400 includes a fastening protrusion 410 and a fastening hole 420. One of the fastening protrusion 410 and the fastening hole 420 is provided on the module thermal insulation cover 330, while the other is provided on the inner wall of the assembly slot 102. Thus, the fastening protrusion 410 and the fastening hole 420 cooperate to increase the strength of the connection between the module thermal insulation cover 330 and the assembly slot 102.
