Description
Technical Field
[0001] The present invention belongs to the technical field of refrigerators, and in particular relates to an anti-condensation device and an intelligent refrigerator comprising the same. Background Art
[0002] Smart refrigerators, due to their unmanned vending capabilities, are popular in convenience stores, community supermarkets, and other locations. To identify products and monitor consumer behavior, smart refrigerators typically feature cameras above the entrances. Some also include light strips for nighttime product identification.
[0003] When the refrigerator door is opened and closed, condensation is easily generated on the door and the edge of the cabinet opening due to the contact between the external hot and humid air and the low-temperature surface inside the refrigerator. In the prior art, Chinese invention patent application CN108759225A discloses a cabinet opening drainage structure for a horizontal refrigerator and a horizontal refrigerator. This patent discharges condensation by setting a drain outlet at the corner of the cabinet opening. However, in actual application, it is found that when the drain outlet is set at the corner, the condensation flows slowly at the corner, the drainage efficiency is low, and it is easy to accumulate ice, resulting in the formation of icicles, which in turn hinders the drainage effect. Therefore, the design of the corner drainage structure still has the problem of condensation retention, which cannot meet the demand for efficient drainage. Long-term accumulation will cause the lens to be blurred, the image quality to deteriorate, and may even cause circuit corrosion due to moisture, seriously affecting the stability and service life of the camera, thereby reducing the reliability of the unmanned vending machine of the smart refrigerator.
[0004] Therefore, how to solve the condensation problem at the current intelligent refrigerator cabinet door is a technical problem that needs to be solved urgently. Summary of the Invention
[0005] In response to the shortcomings of the prior art, the present invention provides an anti-condensation device and an intelligent refrigerator including the same. The anti-condensation device significantly improves the condensation discharge efficiency by arranging a drainage trough in the middle of the front wall of the cabinet opening, thereby avoiding the ice blockage problem caused by drainage at the corners; the guide trough is arranged on the lower side and middle beam of the cabinet door, with a height higher than the drainage trough, actively guiding the condensation to flow to the drainage trough and serving as a slide, thereby reducing the damage of condensation retention to the camera and circuit and realizing structural and functional integration.
[0006] The present invention provides an anti-condensation device, which is arranged at a cabinet opening on the top of a cabinet body. The top of the cabinet body is higher in front and lower in the back. The top of the cabinet body is provided with a cabinet door that opens from the front to the back. The anti-condensation device includes:
[0007] A drainage trough is provided inside the lower front wall of the cabinet opening, and a drainage port is provided in the middle of the drainage trough for draining condensation;
[0008] The guide trough is installed on the side and middle beam of the refrigerator cabinet opening. The guide trough is set under the cabinet door. The height of the guide trough is higher than the drainage trough. It is used to guide the condensation generated at the cabinet opening to flow into the drainage trough and also serves as a slide for the cabinet door.
[0009] The anti-condensation device of this technical solution significantly improves the condensation discharge efficiency by arranging the drainage groove in the middle of the front wall of the cabinet opening, avoiding the ice blockage problem caused by drainage at the corners; the guide groove is arranged on the side and middle beam below the cabinet door, and its height is higher than the drainage groove, actively guiding the condensation to flow into the drainage groove and serving as a slide, which not only reduces the damage of condensation retention to the camera and circuit, but also realizes structural function integration.
[0010] In some embodiments, a water retaining rib is provided on one side of the guide channel opposite the cabinet opening. The rib is higher than the guide channel and is used to prevent condensation from flowing along the side of the guide channel into the cabinet. This technical solution uses the water retaining rib to prevent condensation from flowing along the side of the guide channel into the cabinet, preventing condensation from seeping into the refrigerator interior and causing circuit corrosion or product contamination.
[0011] In some embodiments, a basket is provided within the refrigerator liner, with a gap defined between the liner and the basket. Water retaining strips are installed on the upper portions of the front and side walls of the liner. The water retaining strip on the front wall is the same length as the front wall, while the water retaining strip on the side wall is longer than the width of the openable door. This technical solution, through the provision of water retaining strips and their specified dimensions, ensures that condensation is fully intercepted and diverted, preventing it from flowing down the liner walls and freezing. Together with the drainage and diversion troughs, this prevents condensation from freezing on the cabinet walls.
[0012] In some embodiments, the water retaining bar is provided with a downwardly curved guide portion, the horizontal width of the guide portion being greater than the width of the gap, for guiding condensation into the basket while preventing foreign objects from falling into the gap.
[0013] In some embodiments, the water retaining strip has a connecting portion at the bend between the front wall and the side wall of the inner liner, and the connecting portion conforms to the shape of the bend. This technical solution ensures that condensation can be effectively intercepted and diverted even in the bend area, avoiding condensation leakage due to structural discontinuities.
[0014] In some embodiments, the water retaining bar is provided with a mounting portion that is fixedly attached to the inner container wall, and the top of the mounting portion is fixedly connected to the top of the guide portion. This technical solution ensures a stable structure by providing the mounting portion, and prevents the water retaining bar from loosening or deforming due to frequent opening and closing of the refrigerator.
[0015] In some embodiments, a drain pipe is provided within the cabinet front wall, connected to a drain port, to guide condensation out. This technical solution, through the provision of a drain pipe, directs condensation to a designated discharge location, preventing it from flowing or leaking freely within the cabinet, improving drainage efficiency, and reducing the risk of water accumulation within the cabinet.
[0016] In some embodiments, a water collection box is provided at the bottom of the cabinet to collect condensation, and the water collection box is detachably connected to the cabinet bottom. This technical solution uses the water collection box to centrally collect condensation, preventing water stains from contaminating the surrounding environment of the refrigerator. The detachable structure also facilitates regular cleaning, improving user convenience.
[0017] In some embodiments, the cabinet doors include a front door and a rear door, with the rear door being taller than the front door. The front door utilizes frameless glass and has end stops on both sides of the front door, which are higher than the upper surface of the front door and are used to prevent condensation on the door from flowing into the cabinet. This technical solution, by providing end stops on the left and right sides of the front door, blocks condensation from flowing into the cabinet, preventing condensation from affecting the goods or electronic components inside and improving moisture-proofing.
[0018] The present invention also provides a smart refrigerator, comprising a cabinet body with a top that is higher in front and lower in back, and a cabinet opening. A door is provided on the top of the cabinet body that opens from front to back, and the above-described anti-condensation device is installed inside the cabinet opening. This technical solution can systematically optimize the drainage path, reduce condensation accumulation, and ensure camera clarity and device stability.
[0019] Based on the above solution, the anti-condensation device in the embodiment of the present invention significantly improves condensation drainage efficiency by locating a drainage trough in the middle of the cabinet front wall, avoiding ice blockage caused by corner drainage. A diversion trough is located on the lower side of the cabinet door and on the center beam, at a height higher than the drainage trough, actively guiding condensation toward the trough and also serving as a slide. This not only reduces damage to the camera and circuit caused by condensation retention, but also achieves structural and functional integration. This overall design effectively solves the problems of low efficiency and condensation accumulation in existing drainage structures, improving the reliability and service life of smart refrigerators.

[0038] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0039] In the description of the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.
[0040] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0041] like Figures 1-11 As shown, in one embodiment of the anti-condensation device and the intelligent refrigerator including the same of the present invention, as shown in FIG. Figure 1 As shown, the anti-condensation device is arranged at the cabinet opening on the top of the cabinet body 1. The top of the cabinet body 1 is high in the front and low in the back. A cabinet door that opens the cabinet opening from front to back is provided on the top of the cabinet body 1. The anti-condensation device includes a drainage groove 2 and a guide groove 3. The drainage groove 2 is arranged inside the lower front wall of the cabinet opening, and a drainage outlet 201 for discharging condensation is opened in the middle of the drainage groove 2; the guide groove 3 is installed on the side of the cabinet opening and the middle beam 9, and the guide groove 3 is arranged below the cabinet door. The height of the guide groove 3 is higher than the drainage groove 2, and is used to guide the condensation generated at the cabinet opening to flow into the drainage groove 2, and also serves as a slide for the cabinet door to slide.
[0042] In the above-described exemplary embodiment, the anti-condensation device significantly improves condensation drainage efficiency by locating a drain trough 2 in the middle of the cabinet's front wall, preventing ice blockage caused by corner drainage. A guide trough 3, located below the cabinet door and on the center beam 9, is positioned at a height higher than the drain trough 2. This actively guides condensation toward the trough 2 and also serves as a slideway, minimizing damage to the camera 10 and circuitry caused by condensation retention while achieving structural and functional integration. This overall design effectively addresses the issues of low drainage efficiency and condensation accumulation in existing drainage structures, enhancing the reliability and service life of smart refrigerators.
[0043] In some embodiments, as Figure 2 As shown, a water retaining rib 301 is provided on one side of the guide groove 3 relative to the side of the cabinet opening. The water retaining rib 301 extends from the guide groove 3 and is used to prevent condensation from flowing into the cabinet along the side of the guide groove 3. The provision of the water retaining rib 301 prevents condensation from flowing into the cabinet along the side, preventing condensation from seeping into the interior of the refrigerator and causing circuit corrosion or product contamination, thereby improving the accuracy of the drainage direction.
[0044] Furthermore, the water retaining strip 5 is integrally formed with the guide groove 3. The integrated structural design enhances the connection strength between the water retaining strip 5 and the guide groove 3, preventing the water retaining strip 5 from loosening or falling off due to long-term use, thereby improving the reliability of condensation prevention, simplifying the manufacturing process, and reducing production costs.
[0045] In some embodiments, as Figure 5 As shown, the end of the guide groove 3 extends above the drainage groove 2. Extending the end of the guide groove 3 directly above the drainage groove 2 ensures that condensation can flow smoothly into the drainage groove 2, preventing condensation from dripping or stagnating at the end of the guide groove 3, further improving drainage efficiency and reducing the risk of condensation overflow.
[0046] Furthermore, the bottom of the guide trough 3 is provided with an inclined guide surface, with the end of the guide surface close to the drainage trough 2 being lower than the end of the guide surface away from the drainage trough 2. The design of the inclined guide surface allows condensation to flow naturally toward the drainage trough 2 under the action of gravity, reducing condensation residue, optimizing the diversion effect, improving drainage smoothness, and avoiding water accumulation at the bottom of the trough.
[0047] In some embodiments, as Figure 2 As shown, a pulley is provided at the bottom of the cabinet door for sliding. The guide groove 3 is provided with a positioning groove 302 for positioning the pulley. The water retaining rib 301 maintains a continuous structure at the positioning groove 302. The precise coordination between the positioning groove 302 and the pulley ensures stable sliding of the cabinet door. At the same time, the water retaining rib 301 maintains a continuous structure at the positioning groove 302, preventing condensation from seeping into the cabinet through the positioning groove 302 and maintaining the overall sealing.
[0048] In some embodiments, as Figure 1 As shown, the anti-condensation device also includes a water retaining bar 5. A basket 4 is provided in the inner liner of the refrigerator, with a gap provided between the inner liner and the basket 4. The water retaining bar 5 is installed on the upper part of the front wall and the side walls of the inner liner. The water retaining bar 5 on the front wall of the inner liner is the same length as the front wall of the inner liner, and the water retaining bar 5 on the side wall of the inner liner is longer than the width of the openable cabinet door. By providing the water retaining bar 5 and limiting its size, condensation is ensured to be fully intercepted and diverted, preventing condensation from flowing down the inner liner wall and freezing. Together with the drainage groove 2 and the guide groove 3, condensation is prevented from freezing on the cabinet wall. It should be noted that for smart refrigerators, this can also avoid affecting the gravity sensor measurement installed at the bottom of the smart refrigerator.
[0049] In some embodiments, as Figure 1 As shown, the water retaining bar 5 is provided with a downwardly curved guide portion 52 , the horizontal width of which is greater than the width of the gap, for guiding condensation into the basket 4 while preventing foreign objects from falling into the gap.
[0050] In some embodiments, as Figure 2As shown, the water retaining strip 5 has a connecting portion 54 at the corner where the front wall and the side wall of the inner container meet. This connecting portion 54 conforms to the shape of the corner. As an illustrative embodiment, the corner is curved, so the connecting portion 54 is designed to be curved. By providing a form-fitting connecting portion 54 at the corner between the front wall and the side wall of the cabinet 1, condensation can be effectively intercepted and directed even in the corner, preventing condensation leakage due to structural discontinuities.
[0051] In some embodiments, as Figure 3 As shown, the water retaining bar 5 is provided with a mounting portion 51, which is fixedly connected to the inner wall of the refrigerator, and the top of the mounting portion 51 is fixedly connected to the top of the guide portion 52. The installation of the mounting portion 51 ensures a stable structure, prevents the water retaining bar 5 from loosening or deforming due to frequent opening and closing of the refrigerator, and improves reliability in long-term use.
[0052] In some embodiments, as Figure 3 As shown, a support portion 53 for structural reinforcement is provided between the mounting portion 51 and the diversion portion 52. The ends of the support portion 53 are fixedly connected to the mounting portion 51 and the diversion portion 52, respectively. As an illustrative embodiment, to simplify installation, the mounting portion 51 is not provided at the bend. The provision of the mounting portion 51 facilitates installation of the water retaining bar 5 without affecting its overall diversion function.
[0053] In some embodiments, as Figure 4 As shown, the mounting portion 51 is provided with a mounting hole 511. The arrangement of the mounting hole 511 facilitates the positioning and fixing of the mounting portion 51, thereby improving the installation efficiency and structural stability of the water retaining bar 5.
[0054] Furthermore, a bolt for fixing the mounting portion 51 is passed through the mounting hole 511. The mounting portion 51 is fixed by the bolt through the mounting hole 511 to ensure that the mounting portion 51 is firmly connected to the cabinet wall and prevent the water retaining bar 5 from loosening due to vibration of the refrigerator.
[0055] In some embodiments, as Figure 4 As shown, a support portion 53 for strengthening the structure is provided between the mounting portion 51 and the guide portion 52, and both ends of the support portion 53 are fixedly connected to the mounting portion 51 and the guide portion 52. The arrangement of the support portion 53 enhances the overall strength of the water retaining bar 5 and prevents the guide portion 52 from being deformed by external forces.
[0056] In some embodiments, as Figure 1 As shown, at least one drain outlet 201 is provided. Providing at least one drain outlet 201 ensures that condensation can be effectively drained, avoiding blockage or insufficient drainage capacity of a single drain outlet 201 and improving the reliability of the drainage system. As an illustrative embodiment, two drain outlets 201 are provided at the cabinet entrance, aligned with the centerlines of the two cabinet doors.
[0057] Further, if Figure 7 As shown, the cabinet opening is provided with a mounting member 202 for mounting the drain outlet 201. The mounting member 202 allows the drain outlet 201 to be firmly fixed to the cabinet opening, preventing the drain outlet 201 from shifting or falling off due to vibration of the refrigerator or long-term use, thereby ensuring the long-term effectiveness of the drainage structure.
[0058] In some embodiments, as Figure 9 As shown, the mounting member 202 is fixedly connected to the cabinet opening by means of bolts 203. The bolt 203 connection method is adopted to make the mounting member 202 more firmly fixed.
[0059] In some embodiments, as Figure 8 As shown, a drain pipe 6 is installed in the front wall of the cabinet 1 and connected to the drain port 201 to guide condensation out. This arrangement directs condensation to a designated location, preventing it from flowing or leaking freely within the cabinet 1. This improves drainage efficiency and reduces the risk of water accumulation within the cabinet. As an illustrative embodiment, to simplify installation, the drain pipe 6 is plugged into the drain port 201, and the drain port 201 and mounting member 202 are integrally formed.
[0060] In some embodiments, as Figure 10 As shown, a fixing seat 601 for fixing the drain pipe 6 is provided at the bottom of the cabinet 1. The setting of the fixing seat 601 ensures that the drain pipe 6 remains stable during the operation of the refrigerator to prevent the drain pipe 6 from loosening or falling off due to vibration or external force.
[0061] It should also be noted that, in this embodiment, Figure 7 The two drain outlets 201 shown are respectively arranged at positions aligned with the center lines of the two cabinet doors, and the fixing seat 601 is arranged in the middle of the bottom of the cabinet body 1, so that the drain pipe 6 can form a certain slope. Compared with the drain outlets 201 arranged on both sides of the cabinet opening in the prior art, this embodiment is more conducive to the discharge of condensation.
[0062] In some embodiments, as Figure 6 and Figure 8 As shown, a water collecting box 7 for collecting and discharging condensation is provided at the bottom of the cabinet 1, and the water collecting box 7 is detachably connected to the bottom of the cabinet 1. The water collecting box 7 can collect the discharged condensation in a centralized manner to prevent water stains from contaminating the environment around the refrigerator. At the same time, the detachable structure facilitates regular cleaning and improves the convenience of use.
[0063] In some embodiments, as Figure 10 As shown, the bottom of the cabinet 1 is provided with a card slot 8, and the water collection box 7 is snapped into the card slot 8. The snap connection between the card slot 8 and the water collection box 7 makes installation and removal faster, and the operation can be completed without additional tools, thereby improving user experience and maintenance efficiency.
[0064] In some embodiments, as Figure 10 As shown, the water collecting box 7 is provided with a snap-fit portion 701 that matches the slot 8. The water collecting box 7 is detachably connected to the slot 8 by snap-fitting. The provision of the snap-fit portion 701 enhances the precision of the fit between the water collecting box 7 and the slot 8, ensuring that the water collecting box 7 is securely installed, preventing water leakage or falling off due to looseness, and improving the reliability of the overall structure.
[0065] In some embodiments, the cabinet door includes a front cabinet door and a rear cabinet door, and the rear cabinet door is higher than the front cabinet door ( Figure 1 The front door is not shown). Figure 11 As shown, the front door uses frameless glass 11, and end stops 12 are provided on the left and right sides of the front door. The end stops 12 are higher than the upper surface of the front door and are used to prevent condensation on the door from flowing into the interior of the cabinet body 1. It should be noted that the front door can be slid open or closed, and the guide groove 3 also serves as a slide for the front door. By providing end stops 12 on the left and right sides of the front door, condensation on the door surface is prevented from flowing into the cabinet, preventing condensation from affecting the internal goods or electronic components, and improving the moisture-proof effect; the left and right end stops 12 of the front door, together with the drainage groove 2, the guide groove 3, and the water retaining bar 5, constitute the four lines of defense of the anti-condensation device.
[0066] Based on the above-mentioned anti-condensation device, the present invention further provides a smart refrigerator, comprising a cabinet body 1 having a top that is higher in front and lower in back, and having a cabinet opening. The cabinet body 1 is provided with a door that opens from front to back, and the cabinet opening is provided with the above-mentioned anti-condensation device inside. The smart refrigerator adopts a cabinet top structure that is higher in front and lower in back, combined with anti-condensation devices such as a drainage trough 2, a guide trough 3, and a water retaining bar 5, to systematically optimize the drainage path, reduce condensation accumulation, and ensure the clarity of the camera 10 and the stability of the equipment.
[0067] In some embodiments, as Figure 2 As shown, a camera 10 is also installed in the cabinet 1. The camera 10 is installed below the drain groove 2 at the corner of the cabinet opening and above the water barrier 5. By placing the camera 10 below the drain groove 2, the shielding effect of the drain groove 2 is utilized to reduce the possibility of condensation dripping directly onto the camera 10, thereby reducing the risk of lens blur and circuit moisture, extending the service life of the camera 10, and ensuring the stability of the intelligent recognition function.
[0068] Through the description of multiple embodiments of the anti-condensation device of the present invention and the smart refrigerator including the same, it can be seen that the anti-condensation device of the present invention and the smart refrigerator including the same have at least one or more of the following advantages:
[0069] 1. The anti-condensation device provided by the present invention significantly improves the condensation discharge efficiency by arranging the drainage groove 2 in the middle of the front wall of the cabinet opening, and avoids the problem of ice blockage caused by corner drainage;
[0070] 2. The anti-condensation device provided by the present invention has a guide groove 3 located on the lower side of the cabinet door and the center beam 9, which is higher than the drainage groove 2. This actively guides condensation to flow into the drainage groove 2 and also serves as a slideway, thereby reducing the damage caused by condensation to the camera 10 and circuits and achieving structural and functional integration.
[0071] 3. The anti-condensation device provided by the present invention ensures that condensation is fully intercepted and diverted by setting a water retaining bar 5 and limiting the size of the water retaining bar 5, thereby preventing condensation from flowing down the inner tank wall and freezing. Together with the drainage groove 2 and the guide groove 3, it prevents condensation from freezing on the cabinet wall.
[0072] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0073] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the same. Although the present invention has been described in detail with reference to preferred embodiments, persons skilled in the art should understand that the specific implementation methods of the present invention may still be modified or some technical features may be replaced by equivalents without departing from the spirit of the technical solutions of the present invention, and all of these should fall within the scope of the technical solutions claimed for protection by the present invention.
