Description

Technical Field

[0001] This invention belongs to the field of refrigeration equipment, specifically relating to an intelligent refrigerator that can accurately obtain information on the quantity of items inside the refrigerator. Background Technology

[0002] Refrigerators, as one of the most commonly used home appliances for storing items, typically have multiple relatively independent storage compartments. However, current users have a wide variety and quantity of items that need refrigeration and preservation, requiring refrigerators to provide even more space to meet their categorized storage needs. Generally, refrigerators have shelves in the refrigeration compartment for storing items, and additional storage boxes are often added to the refrigerator door to increase storage space. However, existing storage shelves / boxes only have a storage function and lack the ability to sense and monitor the stored items. For example, if the stored items are consumer goods such as beverages / alcohol, monitoring the storage status of the storage boxes can provide information on the current inventory of items on the refrigerator's shelves and in the storage boxes, such as how many beverages / alcohol items remain and which storage areas have had beverages / alcohol items removed, facilitating restocking and counting.

[0003] Chinese Patent 201610374491.5 discloses a refrigerator and a method for determining changes in items within its storage area. The refrigerator includes a cabinet, an image acquisition device, a human detection device, and a control device. The cabinet contains a storage area for storing items. The image acquisition device acquires images of items within the storage area. The human detection device detects human signals when items are retrieved or placed within the storage area and generates a human detection signal. The control device acquires the human detection signal and determines that an item has been retrieved or placed within the storage area. After the item is retrieved or placed, the control device acquires an image of the items within the storage area and compares this image with an image of the items within the storage area before the item was retrieved or placed to determine changes in the items within the storage area after the retrieval or placement. In the aforementioned prior art, image acquisition of items is required, which can be difficult to accurately identify when items are stored crowdedly, have similar appearances, or the space is limited. Summary of the Invention

[0013] According to one specific embodiment of the present invention, the sensing plate is mounted on a fixed base and can move laterally between the first vertical beam and the second vertical beam, so that the plug can mate with or detach from the first plug portion.

[0014] According to a specific embodiment of the present invention, the sensing plate is limited and assembled on the fixed base by at least one set of snap-fit ​​mechanisms; the snap-fit ​​mechanism includes a slot and a buckle that cooperate with each other;

[0015] In the transverse direction, the slot has a first slot and a second slot with different widths, and the first slot and the second slot are connected to each other;

[0016] In the vertical direction, the buckle has a first wall portion and a second wall portion formed by bending;

[0017] The second wall portion can pass through the wider second groove portion in the vertical direction. When the sensing plate moves laterally to the point where the connector and the first connector portion align, the first wall portion moves to the narrower first groove portion, so that the second wall portion is located above or below the first groove portion for vertical positioning.

[0018] According to one specific embodiment of the present invention, the assembled second vertical beam abuts against the other end of the sensing plate to limit the lateral movement of the sensing plate.

[0019] According to one specific embodiment of the present invention, the detection switch is a non-contact infrared sensor.

[0020] According to a specific embodiment of the present invention, a storage shelf is provided in the refrigeration room, and the storage shelf is movably arranged in the refrigeration room along the front-rear direction of the box; wherein, a second plug is provided on the rear end side of the storage shelf, and a second plug portion electrically engaged with the second plug is provided in the box.

[0021] According to a specific embodiment of the present invention, the storage shelf has multiple storage areas, each storage area being equipped with a pressure sensor; the pressure sensor is used to detect the storage status of its corresponding storage area, and sends the detected storage area status information to a control board electrically connected to the pressure sensor via a second connector and a second connector portion, so as to obtain the item inventory information of the storage shelf.

[0022] According to a specific embodiment of the present invention, a mounting groove is provided on the side wall of the refrigeration compartment, and the storage shelf has a lateral edge portion, which can slide along the mounting groove to push the storage shelf in or pull it out.

[0025] According to a specific embodiment of the present invention, a sliding groove is provided on the side wall of the refrigeration compartment, and a movable locking member is disposed in the sliding groove; the sliding groove and the mounting groove intersect; wherein, the mating part has a notch groove, and the limiting part has a limiting post, when the storage shelf is fully pushed in and the movable locking member is switched to the locking position, the limiting post extends into the notch groove to form a locking fit.

[0026] The present invention has the following beneficial effects:

[0027] This invention uses multiple detection switches to directly detect different storage compartments of a storage box, obtaining the storage status of each compartment and the amount of items stored in the box. This allows for targeted processing of the storage box's usage. Simultaneously, a gap is formed between the mounting base and the storage box, preventing contact between the box and the detection switches. During use, items inside the storage compartments do not directly rest on the detection switches, ensuring effective detection even for light items. Furthermore, the absence of contact between the box and the detection switches prevents damage caused by direct contact with the switches.

[0028] To more clearly illustrate the purpose, technical solution, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0040] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0042] This invention provides an intelligent refrigerator, such as... Figure 1-2 As shown, the device includes a cabinet 10 and a door 20; the cabinet 10 contains a refrigeration compartment 11, and the door 20 is mounted on the cabinet 10 to open and close the refrigeration compartment 11; in this embodiment of the invention, the refrigeration method of the refrigeration compartment 11 is a semiconductor refrigeration system, i.e., a semiconductor refrigerator, suitable for places such as hotel suites, where semiconductor refrigerators offer better noise reduction. Of course, in other usage scenarios, a traditional compressor refrigerator can also be used; this embodiment does not limit the refrigeration method.

[0043] Please continue reading. Figure 2 The refrigeration compartment 11 has a large storage space. Multiple storage shelves 30 are arranged vertically within the refrigeration compartment 11. The storage shelves 30 are movably arranged within the refrigeration compartment 11 along the front-back direction of the cabinet 10. Specifically, the side wall of the refrigeration compartment 11 is provided with a mounting groove 12. The storage shelf 30 has a lateral edge portion 31, which can slide along the mounting groove 12 to push the storage shelf 30 in or pull it out.

[0044] To obtain information about the quantity of items on the storage shelf 30, the storage shelf 30 has a weight detection function; such as... Figure 3 As shown, the storage shelf 30 has a second connector 32 at its rear end and a second connector 13 inside the housing 10. The second connector 32 and the second connector 13 are electrically connected to transmit and record data. The storage shelf 30 has multiple storage areas 33, and each storage area 33 has a built-in pressure sensor. The pressure sensor is used to detect the storage status of its corresponding storage area 33 and sends the detected status information of the storage area 33 to the control board electrically connected to the pressure sensor through the second connector 32 and the second connector 13, thereby obtaining the item storage information of the storage shelf 30.

[0045] In the prior art, the storage shelf 30 is usually a non-fully fixed structure, that is, it is slidably connected to the side wall of the refrigeration compartment 11 through the two side edges of the storage shelf 30 or the guide rails on the two side edges. Under the traditional storage structure, the slight shaking of the storage shelf 30 will not affect the use. However, this structure cannot be directly applied to the shelf structure that requires electrical connection. The slight shaking will cause the connection to loosen, resulting in malfunctions such as poor contact, as well as detection errors caused by the shaking of the detection element, which ultimately leads to the inability to accurately obtain the information on the number of items in the storage shelf 30.

[0046] like Figure 3-4 As shown, a locking mechanism 40 is provided on the side wall of the refrigeration compartment 11. The locking mechanism 40 is used to lock the storage shelf 30 and keep the second connector 32 and the second connector 13 stably connected. The locking mechanism 40 includes a movable locking member 41, which is disposed on the side wall of the refrigeration compartment 11 and can switch between a locked position and an unlocked position. In this embodiment of the invention, the movable locking member 41 switches positions by sliding. In other embodiments, the movable locking member 41 can also switch positions by rotating, which will not be elaborated here.

[0047] Specifically, a mating part 311 is provided on the lateral edge portion 31, and a limiting part 411 corresponding to the mating part 311 is provided on the movable locking member 41. When the storage shelf 30 is fully pushed in, the movable locking member 41 is switched to the locked position, and a locking engagement is formed between the limiting part 411 and the mating part 311, so that the storage shelf 30 is locked.

[0048] Furthermore, a vertical sliding groove 14 is provided on the side wall of the refrigeration compartment 11, and a movable locking member 41 is disposed within the sliding groove 14; wherein, the sliding groove 14 intersects with the mounting groove 12; please refer again. Figure 3 The mating part 311 is specifically a notch, and the limiting part 411 specifically includes multiple limiting posts 412 to enable a single movable locking member 41 to lock different storage shelves 30 at the same time; when the storage shelf 30 is fully pushed in and the movable locking member 41 is switched to the locked position, the limiting post 412 extends into the notch to form a locking fit.

[0049] like Figure 4 As shown, the movable locking member 41 is provided with a relief groove 413 that is adapted to the mounting groove 12; when the movable locking member 41 is in the unlocked position, the lateral edge portion 31 can slide along the relief groove 413; preferably, the limiting post 412 is provided in the relief groove 413, specifically it can be provided on the top wall of the relief groove 413; in other embodiments, the limiting post 412 can also be provided on the bottom wall or side wall of the relief groove 413, as long as it can cooperate with the notch groove.

[0050] Please refer to it again. Figure 4 The movable locking member 41 has a protruding guide part 414 on its rear side, and the side wall of the refrigeration chamber 11 has a guide groove 15 that is parallel to and connected to the slide groove 14. The guide part 414 is slidably disposed in the guide groove 15 to form an up-and-down sliding guide. Of course, the guide part 414 can also be disposed on the front side of the movable locking member 41, which will not be elaborated here.

[0051] The locking mechanism 40 in this embodiment of the invention further includes one or more elastic locking feet 42, which are disposed on the movable locking member 41 to determine the current position when the movable locking member 41 slides up and down; for example Figure 4 As shown, the elastic locking foot 42 and the guide portion 414 are located on the same side of the movable locking member 41; wherein, the guide groove 15 is provided with two locking slots 151 corresponding to the elastic locking foot 42, and the two locking slots 151 are arranged vertically to correspond to the movable locking member 41 being in the locked position and the unlocked position respectively.

[0052] Specifically, the slot 151 is preferably an arc-shaped slot. The elastic locking foot 42 will be squeezed and elastically deformed during the up-and-down sliding of the movable locking member 41, so that the operator can determine whether the movable locking member 41 has moved into place based on the feedback change of the force.

[0053] like Figure 1 As shown, the inner liner of the door body 20 is provided with a storage box 50 with a small storage space. When the door body 20 is closed, the storage box 50 is located in the refrigeration chamber 11. The inner liner 21 of the door body 20 is provided with a first vertical beam 22 and a second vertical beam 23 extending side by side along the vertical direction. The storage box 50 can be freely installed and detached between the first vertical beam 22 and the second vertical beam 23.

[0054] like Figure 6-7 As shown, the first vertical beam 22 and the second vertical beam 23 are provided with guide protrusions 24 on their respective inner sides, and the storage box 50 is provided with locking grooves 51 on their respective sides. In the height direction, the locking grooves 51 can engage with the guide protrusions 24 to facilitate the quick assembly and disassembly of the storage box 50. Preferably, the guide protrusions 24 and the locking grooves 51 are trapezoidal in shape to improve stability.

[0055] Furthermore, a stop 25 is provided on the inner side of the first vertical beam 22 and the second vertical beam 23, and the stop 25 is located above the guide protrusion 24. When the storage box 50 is installed on the first vertical beam 22 and the second vertical beam 23, the stop 25 is slightly higher than the top edge of the storage box 50 to limit the shaking of the storage box 50 within a small range. Based on the presence of the stop 25, the storage box 50 can remain stable during the opening and closing of the door 20, thereby improving structural stability. When it is necessary to remove the storage box 50, only a large external force is needed to remove the storage box 50. Correspondingly, the stop 25 can also be made of a flexible material that can be deformed.

[0056] In this embodiment of the invention, a detection device 60 is also provided for detecting the items placed inside the storage box 50. Unlike the larger space of the storage shelf 30, the storage space of the storage box 50 is smaller, and the structure of the storage box 50 is also smaller. Correspondingly, the volume and weight of the items stored inside are also smaller. It is difficult to obtain accurate detection results using a weight-based pressure sensor. Therefore, in this embodiment of the invention, a special non-contact detection device 60 is used to accurately obtain the storage status inside the storage box 50.

[0057] like Figure 5-6 As shown, the detection device 60 includes a fixed base 61 and a plurality of detection switches 62 disposed on the fixed base 61, wherein the detection switches 62 are preferably non-contact infrared sensors; the fixed base 61 is installed on the inner liner 21 of the door body 20 and located below the storage box 50, and a gap is formed between the fixed base 61 and the storage box 50, thereby forming a non-contact detection method between the storage box 50 and the detection switches 62.

[0058] The storage box 50 has multiple partitions 52, which divide the storage space of the storage box 50 into multiple storage cavities 53. Preferably, the partitions 52 are removable to facilitate the placement of different types of items. Each storage cavity 53 has a through hole 54 at its bottom. A detection switch 62 is located directly below the through hole 54 to detect the storage status of the storage cavity 53 and send the detected status information of the storage cavity 53 to a control board electrically connected to the detection switch 62 to obtain the item storage information of the storage box 50. Preferably, the storage cavity 53 has one or more storage positions for placing items, and each storage position has a through hole 54 at its bottom to simultaneously store one or more small items in the storage cavity 53.

[0059] To achieve modular assembly of multiple detection switches 62, such as Figure 8-11 As shown, the detection device 60 also includes a sensing plate 63 disposed on a fixed base 61, and a plurality of detection switches 62 disposed on the sensing plate 63 and corresponding one-to-one with the through holes 54; wherein, a first connector 631 is provided on one end of the sensing plate 63, and a first plug part 221 is provided on the first vertical beam 22, and the first connector 631 and the first plug part 221 are electrically connected to each other to transmit and record data.

[0060] The door 20 is a moving part. During the use of the refrigerator, the door 20 needs to be opened and closed frequently. If the first plug part 221 and the first plug connector 631 are not fully limited, it will lead to unstable connection and poor stability. In other words, the traditional plug-in connection method is prone to causing the first plug connector 631 and the first plug part 221 to separate, resulting in poor contact and other faults, ultimately making it impossible to accurately obtain the information on the number of items in the storage box 50.

[0061] Please continue reading. Figure 8-11 In this embodiment of the invention, the fixed base 61 is installed on the inner liner 21 of the door body 20, the sensing plate 63 is assembled on the fixed base 61, and the sensing plate 63 can move laterally between the first vertical beam 22 and the second vertical beam 23 so that the first plug 631 and the first plug part 221 can be connected or disconnected from each other to facilitate assembly.

[0062] The sensing plate 63 is limited and assembled on the fixed base 61 by two sets of snap-fit ​​mechanisms 70. The snap-fit ​​mechanism 70 includes a slot 71 and a buckle 72 that cooperate with each other. Specifically, the slot 71 is set on the fixed plate, and the buckle 72 is set on the lower surface of the sensing plate 63.

[0063] like Figure 10 As shown, in the horizontal direction (X direction), the slot 71 has a first slot 711 and a second slot 712 with different slot widths. The first slot 711 and the second slot 712 are connected, and the slot width of the first slot 711 is smaller than the slot width of the second slot 712. Here, the slot width refers to the thickness direction (Y direction) perpendicular to the width direction. The buckle 72 has a first wall 721 and a second wall 722 formed by bending in the vertical direction (Z direction). During installation, the second wall 722 can pass through the wider second slot 712 in the vertical direction. When the sensing plate 63 moves horizontally to the point where the first plug 631 and the first plug 221 are connected, the first wall 721 moves to the narrower first slot 711, so that the second wall 722 is located below the slot wall of the first slot 711 for vertical positioning.

[0064] Furthermore, the assembled second vertical beam 23 abuts against the other end of the sensing plate 63 to laterally limit the sensing plate 63.

[0065] To protect the sensing plate 63 and the detection switch 62, the detection device 60 in this embodiment of the invention further includes a protective plate 64, such as... Figure 8-9 As shown, the protective plate 64 is mounted on the mounting base 61 and covers the upper part of the sensing plate 63; the protective plate 64 is provided with a detection hole 641 for the detection switch 62 on the sensing plate 63 to perform detection. Specifically, the sensor can protrude from the detection hole 641 to perform detection.

[0066] Specifically, the protective plate 64 is preferably pre-assembled with the sensing plate 63, for example by means of bolts, clips 72, etc., to protect the sensing plate 63 throughout the assembly process.

[0067] Please continue reading. Figure 8 The assembly process of sensor plate 63 is as follows:

[0068] 1) Install the fixing seat 61 on the inner liner 21 of the door body 20;

[0069] 2) Assemble the first vertical beam 22 onto the inner liner 21 of the door body 20 and position it on the opposite side of the fixing seat 61;

[0070] 3) Assemble the sensor plate 63 on the fixed base 61 and make the first plug 631 mate with the first plug part 221;

[0071] 4) Assemble the second vertical beam 23 on the inner liner 21 of the door body 20 and position it on the opposite side of the fixed seat 61; at this time, the cooperation of the slot 71 and the buckle 72 vertically limits the sensor plate 63, and the second vertical beam 23 contacts the sensor plate 63 to horizontally limit the sensor plate 63, thus completing the limiting assembly of the sensor plate 63.

[0072] This invention can simultaneously detect the inventory information of items on the storage box 50 and the storage shelf 30, allowing relevant personnel to know the current storage status inside the refrigerator at any time. In addition, a network interface can be set on the cabinet 10 to realize remote control, which is conducive to forming a grid-based and intelligent monitoring system. This makes it easy for relevant personnel to know the replenishment status and consumption situation, and can also be further applied to statistics and billing.

[0073] While the present invention has been disclosed above with reference to specific embodiments, these embodiments are not intended to limit the scope of the invention. Any person skilled in the art can make variations / modifications without departing from the scope of the invention; all equivalent variations / modifications made in accordance with the present invention should be covered by the protection scope of the present invention.
