The cover plays a role in shielding and protecting the weighing sensor, thereby improving the waterproof performance of the weighing device and preventing the weighing sensor from being exposed to the outside and easily corroded by water; and a water retaining structure is provided at the edge of the cover and the edge of the base to reduce the possibility of water or other liquids entering the interior of the base from the edge gap between the cover and the base, thereby further improving the waterproof performance and safety of the weighing device.

[0014] In some embodiments of the present application, a groove is provided on the edge of the cover; a protruding side edge is provided on the edge of the base, the protruding side edge is inserted into the groove, and the protruding side edge and the groove side wall forming the groove together form the water retaining structure.

[0015] In the embodiment of the present application, the edge of the cover is provided with inner and outer double-layer side walls to form a groove, which is conducive to improving the structural stability of the cover. In addition, in this embodiment, the groove formed on the edge of the cover opens downward, and no water will accumulate in the groove, further improving the waterproof performance of the weighing device.

[0016] In some embodiments of the present application, a groove is provided on the edge of the base, and a protruding side edge is provided on the edge of the cover. The protruding side edge is inserted into the groove, and the protruding side edge and the groove side wall forming the groove together form the water retaining structure.

[0017] The embodiment of the present application is configured in this way, there is sufficient space for the groove on the base, and the edge of the cover forms a simple protruding side structure, so that the structure of the cover is simple and easy to process.

[0019] In the embodiment of the present application, a groove is formed on the edge of the base, and the opening of the groove is upward, which is convenient for the installation of the cover. In addition, the groove formed on the base has sufficient space and has little impact on the base structure. The cover supports the shelf by setting the cover body, and protects and shields the weighing sensor; the side edges are formed by setting the protruding side edges, which cooperate with the groove to improve the waterproof performance of the weighing device, and the setting of the side edges is also conducive to improving the structural strength of the cover, reducing the deformation of the cover and affecting the weighing accuracy.

[0031] The limiting portion of the embodiment of the present application is a column arranged on the cover. Compared with setting a recessed structure on the cover, setting the column on the cover has a simpler structure and better structural stability of the cover. The embodiment of the present application limits the gap between the column and the side wall of the trough, which can not only reduce the possibility of contact between the column and the side wall of the trough, but also ensure the horizontal limit between the column and the trough, thereby ensuring the accuracy and stability of the weighing of the weighing device.

[0035] In the embodiment of the present application, by setting an avoidance groove for avoiding the hanging ears on the shelf, the horizontal displacement of the shelf is limited, and there is no need to set an additional horizontal limit structure, which is conducive to simplifying the structure of the shelf.

[0056] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0057] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0058] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.

[0059] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0060] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0061] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] As people's requirements for additional functions of refrigerators gradually increase, some refrigerators are equipped with weighing devices to obtain the weight of items. The weighing devices in the related art have poor waterproof performance. The weighing sensor is exposed when the storage container is detached and is easily corroded by liquid, especially when there are inevitably liquid items in the refrigerator or when cleaning the refrigerator.

[0063] The developers of this application have considered the storage status of items in the refrigerator, and compared with setting the weighing device in the box, arranging the weighing device on the door body is more conducive to waterproofing. To this end, in the refrigerator of the embodiment of this application, the weighing device is arranged on the door body, and the storage container of the weighing device can use the existing door shelf to visually hide the base of the weighing device, which is conducive to improving the aesthetics of the refrigerator door body.

[0064] The researchers of this application further considered how to improve the waterproof performance of the weighing device. In the related art, the waterproof performance of the weighing device is poor due to the exposure of the weighing sensor.

[0065] For this reason, the researchers of this application considered setting a cover to shield and protect the weighing sensor and other electrical parts in the base. In addition, the cover is in contact with the weighing sensor, and there is a gap between the cover and the base to ensure the accuracy of weighing.

[0066] During subsequent experimental operations, the researchers discovered that there was horizontal movement between the cover and the base, which not only affected the accuracy of the weighing, but also caused abnormal noise during the door opening and closing process.

[0067] Researchers further discovered that because there are multiple weighing sensors, the cover has a large area, and the contact area between the cover and the storage container is large, when the refrigerator door is opened and closed, the cover and the storage container above it are affected by inertia and have horizontal displacement, which produces abnormal noise. In addition, there is still a risk of water entering the gap between the cover and the base.

[0068] To this end, the researchers of this application set up a concave-convex matching structure between the cover and the base, which can not only limit the horizontal movement, but also play a waterproof role.

[0069] The base is provided with a groove, and the edge of the cover is inserted into the groove. Alternatively, the cover is provided with a groove, and the protruding structure on the base is inserted into the groove on the cover. Since there is insufficient space for the groove on the cover, and there is sufficient space for the groove on the base, and the groove can be formed simultaneously by one-piece molding, the researchers of this application set the groove on the base, so that the edge of the cover is directly inserted into the groove of the base, which has a simple structure and is easy to process.

[0070] During the subsequent research and development process, it was discovered that when water enters the groove of the base, the water tends to overflow into the base, thereby corroding the electrical components inside the base.

[0071] To this end, the researchers of the present application set up an overflow structure on the outer wall of the groove, so that when water enters the groove, the water overflows outward instead of overflowing into the base.

[0072] For example, overflow holes and overflow ports are provided on the outer side wall of the groove so that water in the groove can overflow outwards.

[0073] The developers of this application considered how to set up a simple overflow structure. The overflow hole and the overflow port require additional machining of the base to form the overflow hole, which increases the process. Alternatively, when the base is integrally molded by injection molding, the overflow hole or the overflow port is formed at the same time. In this case, the molding mold needs to be changed, and the structure of the overflow hole and the overflow port is small, which makes the design and processing of the mold complicated.

[0074] The researchers of this application considered how to form a water overflow structure that is simple in structure and easy to process. First, the water overflow structure can be formed during the injection molding of the base without the need for additional machining; second, the water overflow structure has little change to the molding mold, making molding easier.

[0075] On the basis of the overflow outlet, the researchers of this application reduced the overall height of the outer wall of the groove to form a larger overflow outlet, so that the water in the groove overflows outward; moreover, the design of the overflow structure will not lead to the complexity of the base molding mold structure, and molding is relatively easy, which is conducive to reducing processing costs.

[0076] Therefore, the researchers of this application improved the waterproof performance of the weighing device by adding a cover that matches the base in a concave and convex manner and setting an overflow structure on the base.

[0077] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0078] First of all, it should be noted that in the embodiment of the present application, the width direction of the door body corresponds to the X-axis direction in the accompanying drawings; the thickness direction of the door body corresponds to the Y-axis direction in the accompanying drawings; the height direction of the door body, that is, the up and down direction, corresponds to the Z-axis direction in the accompanying drawings.

[0079] Combination Figure 1 and Figure 2 An embodiment of the present application provides a refrigerator, which includes a box body 100, and the box body 100 is structured to form a storage compartment 101 for storing food and other items.

[0080] The storage compartment 101 can be divided into a freezing compartment, a refrigerating compartment, and a temperature-changing compartment according to different storage temperatures. Shelves can be provided in the storage compartment 101 to increase the placement of items; drawers can be provided in the storage compartment 101, which can be pulled out relative to the depth direction of the refrigerator to facilitate the classified storage and retrieval of items.

[0081] In some embodiments, the refrigerator further comprises a door body 200, which is rotatably mounted on the cabinet 100 to open or close the storage compartment 101. Exemplarily, the door body 200 is rotatably connected to the cabinet 100 via a hinge assembly.

[0082] In some embodiments, in combination Figure 2 and Figure 3 At least one shelf 400 is disposed on the door body 200, and the shelf 400 is structured to form a storage cavity 401 with a top opening for storing items.

[0083] In some embodiments of the present application, a shelf 400 is provided on the door body 200 corresponding to the refrigerating compartment.

[0084] In some embodiments, a plurality of shelves 400 may be provided on the door body 200 , and the plurality of shelves 400 are arranged at intervals along the height direction of the door body 200 (corresponding to the Z-axis direction in the drawings) to further increase the storage positions for items.

[0085] In some embodiments, the refrigerator further includes a weighing device 300 , which is located in the storage compartment 101 and is configured to weigh stored items.

[0086] In some embodiments, the weighing device 300 is installed in the box body 100 , so that the weighing environment of the weighing device 300 is stable and is less affected by the opening and closing of the door body 200 .

[0087] In some embodiments, the weighing device 300 is installed on the door body 200 without occupying the storage space of the storage compartment 101 .

[0088] Moreover, the weighing device 300 can weigh the items in one of the shelves 400 without the need for an additional storage structure. In some embodiments, the shelf 400 matched with the weighing device 300 has the same structure as other shelves, and no additional shelf mold needs to be designed, which is conducive to reducing processing costs.

[0089] Of course, the weighing device 300 can be equipped with a storage structure alone to store items and weigh them at the same time.

[0090] In some embodiments, a weighing device 300 may be disposed under each shelf 400 , so as to weigh the items in each shelf 400 .

[0091] In some embodiments of the present application, the weighing device 300 is located under one of the shelves 400 and in contact with the shelf 400 to weigh the items in the shelf 400; the weighing device 300 and the shelf 400 are visually integrated, which helps to improve the aesthetics of the inner side of the door body 200.

[0092] Furthermore, since there is a large gap between the weighing device 300 and the shelf 400 thereunder, the storage space of the shelf 400 is less affected.

[0093] In some embodiments, the projection of the weighing device 300 on the bottom surface of the shelf 400 coincides with the bottom surface of the shelf 400, so that the length of the weighing device 300 is the same as the length of the bottom surface of the shelf 400, and the width of the weighing device 300 is the same as the width of the bottom surface of the shelf 400. This can not only increase the load-bearing area of ​​the weighing device 300, but also make the integration effect of the weighing device 300 and the shelf 400 more significant.

[0094] In some embodiments of the present application, Figure 4 and Figure 5An installation cavity 301 is formed in the weighing device 300 , and a weighing sensor 330 is installed in the installation cavity 301 . The weighing sensor 330 is used for weighing.

[0095] In the embodiment of the present application, the weighing sensor 330 is located in the installation cavity 301 to improve the waterproof performance of the weighing device 300.

[0096] In the embodiment of the present application, at least part of the weighing device 300 is in contact with the weighing sensor 330 , and there is a gap between this part and other parts of the weighing device 300 , and this part is in contact with the shelf 400 , thereby enabling the weighing sensor 330 to weigh the items in the shelf 400 .

[0097] In some embodiments, a water retaining structure 302 is provided at the edge of the weighing device 300 to reduce the possibility of liquid such as water entering the inside of the weighing device 300 from the edge of the weighing device 300 , so as to improve the waterproof performance of the weighing device 300 .

[0098] Combination Figure 5 and Figure 6 In some embodiments, the weighing device 300 includes: a base 310 , and the base 310 is installed on the door body 200 .

[0099] Exemplarily, the base 310 is hung on the door body 200 ; exemplary, the base 310 is snapped onto the door body 200 .

[0100] In some embodiments, the base 310 is provided with ears 316 on both sides along the width direction of the door body, and the ears 316 are connected to the door ribs provided on the door body. The connection method includes but is not limited to snap-on, interference fit, etc., so as to fix the base 310 on the door body.

[0101] In some embodiments, the dimension of the ear 316 along the thickness direction of the door body gradually increases from top to bottom along the height direction, so that the ear 316 is roughly conical on the side, and the size of the position where the ear 316 is connected to the base 310 is larger, which is beneficial to improving the stability and reliability of the connection between the ear 316 and the base 310.

[0102] In some embodiments, Figure 5 and Figure 6 As shown, the weighing device 300 further includes a cover 320 , which covers at least a portion of the base 310 , and a gap is provided between the cover 320 and the base 310 , so that the cover 320 is suspended relative to the base 310 .

[0103] In some embodiments, the cover 320 covers part of the base 310 , and the weighing sensor 330 and other electrical components of the weighing device 300 are located under the cover 320 to provide protection and shielding.

[0104] In some embodiments, the cover 320 is disposed on the outer side of the base 310 , which can not only improve the waterproof performance of the weighing device 300 , but also ensure the aesthetic appearance of the weighing device 300 .

[0105] An installation cavity 301 is formed between the cover 320 and the base 310, so that the weighing sensor 330 is located between the cover 320 and the base 310, so that the cover 320 plays a role in shielding and protecting the weighing sensor 330. The weighing sensor 330 is hidden at the bottom of the cover 320, thereby improving the waterproof performance of the weighing device 300.

[0106] In some embodiments, Figure 6 As shown, there are multiple weighing sensors 330 arranged in a rectangular matrix. Exemplarily, there are four weighing sensors 330, which are respectively arranged at four vertex positions of the base 310.

[0107] By providing a plurality of weighing sensors 330 , the weight of items in the shelf 400 can be better dispersed and detected, thereby improving the accuracy and stability of weighing.

[0108] In the embodiments of the present application, Figures 7 to 9 A water retaining structure 302 is provided at the edge of the cover 320 and the edge of the base 310. The water retaining structure 302 can be a retaining edge to reduce the possibility of liquids such as water entering the interior of the base 310 from the edge gap between the cover 320 and the base 310, thereby improving the waterproof performance of the weighing device 300.

[0109] The top of the cover 320 contacts the shelf 400, so that the weighing sensor 330 weighs the items in the shelf 400 through the cover 320 and the shelf 400. Since there is a gap between the cover 320 and the base 310, the shelf 400 is located on the top of the cover 320, and a horizontal limit structure is provided between the shelf 400 and the weighing device 300 to limit the horizontal displacement of the shelf 400 and prevent the shelf 400 from falling off the weighing device 300. The horizontal position includes movement along the X-axis direction and movement along the Y-axis direction.

[0110] Exemplarily, a horizontal limiting structure is provided between the shelf 400 and the cover 320 ; exemplary, a horizontal limiting structure is provided between the shelf 400 and the base 310 ; exemplary, a horizontal limiting structure is provided between the shelf 400 and the cover 320 , and a horizontal limiting structure is provided between the shelf 400 and the base 310 .

[0111] Therefore, in some embodiments of the present application, the weighing device 300 improves the waterproof performance of the weighing device 300 by providing a cover 320 to shield the weighing sensor 330, thereby preventing the weighing sensor 330 from being exposed to the outside and easily corroded by water; and a water retaining structure 302 is provided at the edge of the cover 320 and the edge of the base 310 to reduce the possibility of water or other liquids entering the interior of the base 310 from the edge gap between the cover 320 and the base 310, thereby further improving the waterproof performance of the weighing device 300.

[0112] In some embodiments, Figure 8 and Fig. 9 As shown, the edge of the base 310 is provided with a groove 311; the edge of the cover 320 is provided with a protruding side 321, and the protruding side 321 is inserted into the groove 311. In this way, there is sufficient space for the groove 311 on the base 310, and the protruding side 321 formed on the edge of the cover 320 is simple in structure, so that the structure of the cover 320 is simple and easy to process.

[0113] Moreover, in this embodiment, the opening of the groove 311 faces upward; when water or other liquid enters the edge gap between the base 310 and the cover 320 , the groove 311 serves to temporarily store the liquid, thereby reducing the possibility of the liquid entering the interior of the base 310 .

[0114] In other embodiments, the edge of the base 310 forms a protruding side, and the edge of the cover 320 forms a groove, and the protruding side is inserted into the groove. The edge of the cover 320 is set in this way, and the inner and outer double-layer side walls are required to form a groove, which is conducive to improving the structural stability of the cover 320.

[0115] Furthermore, in this embodiment, the groove formed on the edge of the cover 320 opens downward, and water will not accumulate in the groove, thereby further improving the waterproof performance of the weighing device 300.

[0116] The protruding side edge 321 and the groove side wall forming the groove 311 form a water retaining structure 302. Under the action of the water retaining structure 302, the possibility of liquids such as water entering the interior from the edges of the base 310 and the cover 320 is reduced, thereby improving the waterproof performance between the base 310 and the cover 320.

[0117] In some embodiments, a groove 311 is formed at the edge of the base 310, and the opening of the groove 311 faces upward, which facilitates the installation of the cover 320. In addition, the groove 311 formed on the base 310 has sufficient space and has little impact on the structure of the base 310.

[0118] Continue to refer to Fig. 9 and Fig.10The cover 320 includes a cover body 322 and a side edge 323 arranged at the edge of the cover body 322 . A weighing sensor 330 is arranged between the cover body 322 and the base 310 . The top surface of the cover body 322 contacts the shelf 400 .

[0119] The side edges 323 are located at the edge of the cover body 322, and the side edges 323 are located at the bottom side of the cover body 322. When the cover body 322 is rectangular, the side edges 323 include four side edges.

[0120] The side edge 323 forms a protruding side edge 321 , and the side edge 323 is inserted into the groove 311 . The side edge 323 cooperates with the groove 311 to improve the waterproof performance of the edge.

[0121] The cover 320 of the embodiment of the present application supports the shelf 400 by setting the cover body 322, and protects and shields the weighing sensor 330; the protruding side edge 321 is formed by setting the side edge 323, which cooperates with the groove 311 to improve the waterproof performance of the weighing device 300, and the setting of the side edge 323 is also beneficial to improving the structural strength of the cover 320, and reducing the deformation of the cover 320 and affecting the weighing accuracy.

[0122] In this embodiment, the side edge 323 of the cover 320 forms a protruding side edge 321 , which has a simple structure and is conducive to reducing processing costs, without the need to additionally provide a complex water retaining structure 302 .

[0123] Continue to refer to Fig. 9 and Fig.11 In some embodiments, the base 310 includes a bottom plate 312, the bottom plate 312 is parallel to the cover 322, and the weighing sensor 330 is located between the bottom plate 312 and the cover 322. The hanging ears 316 are located on both sides of the bottom plate 312 along the width direction of the door body.

[0124] In some embodiments, reinforcing ribs 319 are disposed on the bottom plate 312 to improve the structural strength of the base 310 .

[0125] Exemplarily, a plurality of reinforcing ribs 319 are provided and arranged in a grid pattern, so as to further improve the structural strength of the base 310 .

[0126] There is a gap between the reinforcing rib 319 and the cover 320 to prevent the reinforcing rib 319 from contacting the cover 320 and affecting the accuracy of weighing.

[0127] In some embodiments, the base 310 further includes an inner wall 313 and an outer wall 314 , and the inner wall 313 and the outer wall 314 are groove side walls of the groove 311 , and together with the side surrounding edge 323 form a water retaining structure 302 .

[0128] The inner wall 313 and the outer wall 314 are both arranged on the bottom plate 312, and there is a gap between the inner wall 313 and the outer wall 314. The inner wall 313 is arranged on the side of the outer wall 314 facing the center of the bottom plate 312, and the outer wall 314 is located on the side of the inner wall 313 away from the center of the bottom plate 312. The inner wall 313, the outer wall 314, and the bottom plate 312 between the inner wall 313 and the outer wall 314 form a groove 311, so that not only the groove 311 can be formed, but also the inner wall 313 and the outer wall 314 have a dual water-blocking function, further improving the waterproof performance of the weighing device 300.

[0129] In addition, the cover 320 and the base 310 of the embodiment of the present application can also limit the horizontal displacement of the cover 320 through the cooperation of the protruding side 321 and the groove 311, reduce the possibility of horizontal movement of the cover 320 relative to the base 310, and improve the stability of the structure of the weighing device 300.

[0130] It should be noted that the groove 311 is located inside the ear 316 , that is, the outer wall 314 at the ear 316 is located inside the ear 316 to prevent the ear 316 from affecting the protruding side 321 of the cover 320 from being inserted into the groove 311 .

[0131] In some embodiments, an overflow structure is provided on the outer wall 314. For example, an overflow hole or an overflow port is provided on the outer wall 314. When liquid enters the groove 311, the liquid can overflow outward through the overflow structure, thereby reducing the possibility of liquid entering the inner side of the inner wall 313, thereby reducing the possibility of liquid corroding electrical components such as the weighing sensor 330 in the base 310, and further improving the waterproof performance of the weighing device 300.

[0132] In some possible implementations, at least part of the height of the outer wall 314 is smaller than the height of the inner wall 313 , so that when liquid enters the groove 311 , the liquid can overflow outward through the outer wall 314 with a smaller thickness, reducing the possibility of liquid entering the inner side of the inner wall 313 .

[0133] In some embodiments, the height of the outer side wall 314 can be reduced by machining, and the machining method is flexible.

[0134] In some embodiments, the outer side wall 314 can be formed simultaneously when the base 310 is integrally formed, so that the height of a portion of the outer side wall 314 is lower than the height of the inner side wall 313 , without the need for additional machining, thereby improving production efficiency.

[0135] In some embodiments, the height of the outer side wall 314 is smaller than the height of the inner side wall 313 , so that the liquid in the groove 311 can overflow outwards, and the molding mold is simple when the outer side wall 314 is formed in one piece with the base 310 .

[0136] In some embodiments, the difference between the height of the outer side wall 314 and the height of the inner side wall 313 is 3 mm to 5 mm, for example, the difference between the height of the outer side wall 314 and the height of the inner side wall 313 is 3 mm to 4 mm, 4 mm to 5 mm, etc. Exemplarily, the difference between the height of the outer side wall 314 and the height of the inner side wall 313 is 3 mm, 3.3 mm, 3.5 mm, 3.8 mm, 4 mm, 4.2 mm, 4.5 mm, 4.8 mm or 5 mm, etc.

[0137] Such a configuration can reduce the possibility that the difference between the height of the outer wall 314 and the height of the inner wall 313 is too small, which may cause the liquid in the groove 311 to overflow inward; it can also reduce the possibility that the difference between the height of the outer wall 314 and the height of the inner wall 313 is too large, which may cause the depth of the groove 311 to be too small.

[0138] In some embodiments of the present application, reference Fig. 9 There is a first gap between the groove 311 and the protruding side 321 in the horizontal plane. Specifically, there is a first gap between the groove 311 and the protruding side 321 along the X-axis direction in the horizontal plane, and there is a first gap between the groove 311 and the protruding side 321 along the Y-axis direction in the horizontal plane.

[0139] Such an arrangement reduces the possibility of the cover 320 contacting the base 310 , thereby improving the weighing accuracy of the weighing device 300 .

[0140] If the size of the first gap is less than 0.5 mm, the protruding side edge 321 is likely to contact the groove side wall of the groove 311, resulting in low weighing accuracy.

[0141] In some embodiments, the size of the first gap is greater than or equal to 0.5 mm, so that there is sufficient gap between the protruding side 321 and the side wall of the groove 311, and the possibility of contact between the protruding side 321 and the side wall of the groove 311 is low, which is conducive to ensuring the accuracy of weighing.

[0142] If the size of the first gap is greater than 1.0 mm, the gap between the protruding side 321 and the groove side wall of the groove 311 is large, and the cover 320 is easy to move in the horizontal plane relative to the base 310, which not only has poor stability but also easily affects the accuracy of weighing.

[0143] In some embodiments, the size of the first gap is less than or equal to 1.0 mm. This configuration can avoid excessive gap between the protruding side edge 321 and the groove side wall of the groove 311 , thereby ensuring horizontal limitation between the protruding side edge 321 and the groove 311 .

[0144] In some embodiments, the size of the first gap is 0.5 mm to 1.0 mm, for example, the size of the first gap is 0.5 mm to 0.6 mm, 0.6 mm to 0.7 mm, 0.7 mm to 0.8 mm, 0.8 mm to 0.9 mm, or 0.9 mm to 1.0 mm, etc. Exemplarily, the size of the first gap is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0145] Such a configuration can not only reduce the possibility of the protruding side 321 contacting the groove side wall of the groove 311, but also ensure the horizontal limit between the protruding side and the groove 311, thereby ensuring the accuracy and stability of the weighing of the weighing device 300.

[0146] It should be noted here that, for the portion of the protruding side 321 extending along the X-axis direction, the size of the first gap is the spacing dimension between the protruding side 321 and the groove side wall of the groove 311 along the Y-axis direction; for the portion of the protruding side 321 extending along the Y-axis direction, the size of the first gap is the spacing dimension between the protruding side 321 and the groove side wall of the groove 311 along the X-axis direction.

[0147] In addition, there is a first gap between the protruding side 321 and the inner sidewall 313 of the groove 311, and there is a first gap between the protruding side 321 and the outer sidewall 314 of the groove 311. The two first gaps can be the same or different, which is not limited in the embodiment of the present application.

[0148] In some embodiments of the present application, there is a second gap between the groove 311 and the protruding side edge 321 along the height direction (corresponding to the Z-axis direction in the drawings), and the height direction is perpendicular to the horizontal plane. Specifically, there is a second gap between the bottom plate 312 of the base 310 and the protruding side edge 321 along the height direction to prevent the bottom plate 312 from contacting the protruding side edge 321 and affecting the accuracy of weighing.

[0149] In some embodiments, the ratio of the height of the protruding side 321 inserted into the groove 311 to the height of the groove 311 is 1 / 3 to 1 / 2, that is, the height of the protruding side 321 inserted into the groove 311 accounts for 1 / 3 to 1 / 2 of the height of the groove 311. Such a setting can reduce the possibility of the protruding side 321 being inserted too deep and affecting the horizontal limiting effect, and can also reduce the possibility of the protruding side 321 being inserted too deep and easily contacting the protruding side 321 with the bottom plate 312.

[0150] Combination Fig. 9 and Fig.10 In some embodiments, a limit portion 324 is provided on the cover 320; Fig.11A matching portion 315 is provided on the base 310 , and the limiting portion 324 cooperates with the matching portion 315 to limit the horizontal displacement of the cover 320 .

[0151] When the limiting portion 324 is a protrusion arranged on the cover 320, the matching portion 315 is a recessed portion arranged on the base 310; when the limiting portion 324 is a recessed portion arranged on the cover 320, the matching portion 315 is a protrusion arranged on the base 310; and the protrusion cooperates with the recessed portion to limit the relative displacement between the cover 320 and the base 310 in the horizontal plane.

[0152] In some embodiments of the present application, there is a gap between the limiting portion 324 and the matching portion 315. Specifically, there is a gap between the limiting portion 324 and the matching portion 315 in the horizontal plane, and there is a gap between the limiting portion 324 and the matching portion 315 along the height direction. Such a setting can reduce the contact between the limiting portion 324 and the matching portion 315 and affect the accuracy of weighing.

[0153] In some embodiments of the present application, a limiting portion 324 is provided on the cover 320, and a matching portion 315 is provided on the base 310. The matching between the limiting portion 324 and the matching portion 315 is utilized to improve the convenience of assembling the cover 320 and the base 310, and also to limit the relative displacement between the cover 320 and the base 310 in the horizontal plane.

[0154] In some embodiments, a plurality of limiting portions 324 are provided on the cover 320, and a plurality of matching portions 315 are provided on the base 310. The positions of the matching portions 315 correspond to the positions of the limiting portions 324, and the number of the matching portions 315 and the limiting portions 324 are the same to improve the stability of the matching between the cover 320 and the base 310.

[0155] There are many ways to arrange the plurality of limiting portions 324. For example, the plurality of limiting portions 324 are arranged on the cover 320 in a rectangular matrix, which has a simple structure.

[0156] In some possible implementations, the limiting portion 324 is a column disposed on the cover 320. Compared with providing a recessed structure on the cover 320, providing a column on the cover 320 has a simpler structure and better structural stability of the cover 320.

[0157] The matching portion 315 is a recessed groove formed on the base 310, and the column matches the recessed groove. Exemplarily, a protruding structure, such as a boss, a cylinder, etc., is provided on the base 310, and the recessed groove is a groove provided on the protruding structure. In this way, while forming the recessed groove, the provision of the protruding structure is conducive to improving the structural stability of the base 310.

[0158] Combination Fig. 9There is a third gap between the column and the side wall of the sink. This arrangement reduces the possibility of contact between the column and the sink, ensuring the accuracy of weighing.

[0159] If the size of the third gap is less than 0.5 mm, the column and the side wall of the sink are likely to contact, resulting in low weighing accuracy.

[0160] In some embodiments, the size of the third gap is greater than or equal to 0.5 mm, so that the gap between the column and the side wall of the sink is sufficient, and the possibility of contact between the column and the side wall of the sink is low, which is conducive to ensuring the accuracy of weighing.

[0161] If the size of the third gap is greater than 1.0 mm, the gap between the column and the side wall of the sink is large, and the cover 320 is easy to move relative to the base 310 in the horizontal plane, which not only has poor stability but also easily affects the accuracy of weighing.

[0162] In some embodiments, the size of the third gap is less than or equal to 1.0 mm. Such a setting can avoid an excessively large gap between the column and the side wall of the sink, thereby ensuring horizontal limitation between the column and the sink.

[0163] In some embodiments, the size of the third gap is 0.5 mm to 1.0 mm, for example, the size of the third gap is 0.5 mm to 0.6 mm, 0.6 mm to 0.7 mm, 0.7 mm to 0.8 mm, 0.8 mm to 0.9 mm or 0.9 mm to 1.0 mm, etc. Exemplarily, the size of the third gap is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0164] Such an arrangement can not only reduce the possibility of contact between the column and the side wall of the sink, but also ensure the horizontal limit between the column and the sink, thereby ensuring the accuracy and stability of the weighing of the weighing device 300.

[0165] In some embodiments of the present application, there is a gap between the column and the bottom wall of the sink in the height direction, which reduces the possibility of contact between the column and the bottom wall of the sink.

[0166] Combination Fig.11 In some embodiments, the shelf 400 includes a storage body 410, which forms a storage cavity 401 with a top opening for storing items.

[0167] In some embodiments, the storage body 410 includes a bottom wall 411 and a circumferential side wall 412 disposed on the bottom wall 411 , and the circumferential side wall 412 and the bottom wall 411 together enclose a storage cavity 401 with an open top. The bottom surface of the storage body 410 contacts the top surface of the cover 320 .

[0168] In some embodiments, the shelf 400 also includes a limiting edge 420, which is disposed at the bottom of the storage body 410. Specifically, the limiting edge 420 is disposed at the edge of the bottom surface of the bottom wall 411; the limiting edge 420 is disposed around the outside of the cover 320, and the limiting edge 420 cooperates with the cover 320 to limit the horizontal displacement of the shelf 400, thereby reducing the possibility of relative movement between the shelf 400 and the weighing device 300.

[0169] Thus, the horizontal limiting structure includes the above-mentioned limiting surrounding edge 420 .

[0170] In some embodiments of the present application, the shelf 400 is used to store items by providing a storage body 410, and the structural strength of the shelf 400 can be improved by providing a limiting edge 420, and the limiting edge 420 constitutes at least a part of the horizontal limiting structure to limit the horizontal displacement between the shelf 400 and the weighing device 300.

[0171] In some embodiments of the present application, there is a gap between the limiting edge 420 and the cover 320 , which is beneficial to improve the convenience of assembly between the shelf 400 and the cover 320 .

[0172] Combination Figure 6 In some embodiments, a hanging ear 316 is formed on the base 310, and the hanging ear 316 is hung on the door body, so that the base 310 is installed on the door body.

[0173] In some embodiments, an avoidance groove 413 for avoiding the hanging ear 316 is formed on the shelf 400 . Specifically, the avoidance groove 413 is formed on the circumferential side wall 412 of the storage body 410 .

[0174] There is a gap between the avoidance groove 413 and the hanging ear 316 . Specifically, there is a gap between the side wall of the avoidance groove 413 along the Y-axis direction and the hanging ear 316 , and there is a gap between the side wall of the avoidance groove 413 along the X-axis direction and the hanging ear 316 .

[0175] The horizontal limiting structure includes an avoidance groove 413 and a hanging ear 316 .

[0176] In this way, the cooperation between the avoidance groove 413 on the shelf 400 and the hanging ear 316 can limit the horizontal displacement of the shelf 400.

[0177] In the embodiment of the present application, the relative displacement between the shelf 400 and the weighing device 300 in the horizontal plane is limited by the cooperation between the limiting edge 420 and the cover 320, and the cooperation between the avoidance groove 413 and the hanging ear 316 on the shelf 400, without the need to set up an additional horizontal limiting structure, which helps to simplify the structure of the shelf 400.

[0178] Continue to refer to Fig.12In the embodiment of the present application, the weighing sensor 330 is installed between the cover 320 and the base 310 .

[0179] In some embodiments, the weighing sensor 330 is fixed on the base 310 , and the weighing end of the weighing sensor 330 is in contact with the cover 320 . In this way, the weighing sensor 330 is fixed on the base 310 , which facilitates the assembly of the cover 320 and the base 310 .

[0180] In some embodiments, the weighing sensor 330 is fixed on the cover 320, and the weighing end of the weighing sensor 330 is in contact with the fixing base 310. The weighing sensor 330 and at least part of the wiring are arranged on the cover 320 in this way, which can reduce the possibility of the weighing sensor 330 being corroded by liquids such as water.

[0181] There are many ways to install the weighing sensor 330, such as snap-on, screw-on, etc.

[0182] Combination Fig.11 Taking the weighing sensor 330 fixed on the base 310 as an example, the base 310 is provided with a support member 318 and a buckle 317, both of which are provided on the bottom plate 312 of the base 310, the support member 318 plays a role in supporting the weighing sensor 330, and the buckle 317 is engaged with the weighing sensor 330 to restrict the weighing sensor 330 on the support member 318. With such a configuration, the fixing structure of the weighing sensor 330 is simple, and the installation is simple and convenient.
