Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of refrigeration and freezing equipment, and particularly relates to a refrigerator. BACKGROUND

[0002] In the process of using the refrigerator in daily life, when both hands of the user are holding something, the door cannot be opened by the hand. The user can only put the things in the hand on one side (such as the ground or a table), and then open the door with one hand, and then put the things on one side into the refrigerator one by one. It can be seen that the operation process prolongs the door opening time, causes the cold air in the refrigerator to be easily lost, and the refrigerator needs to be restarted to recover the original refrigeration temperature after the door is closed, thereby causing energy waste. SUMMARY

[0076] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0077] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0078] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0079] In addition, the terms "first", "second" are only used for description purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0080] At present, if there is a door opening assisting structure on the market refrigerator, the door handle of the refrigerator is provided, so as to achieve the purpose of opening the door.

[0081] However, in scenarios where both hands are occupied, users cannot open the door with their hands. A common example is when a user is holding food in both hands and preparing to put it in the refrigerator. They usually need to place the food on the floor or elsewhere and then use at least one hand to open the door. It's clear that when both hands are occupied, users need to free at least one hand to open the door, which is very inconvenient. Furthermore, it increases the time required to open the door, because after opening it, the food that was previously placed aside needs to be put into the refrigerator one by one. During this process, cold air can easily leak out of the refrigerator, causing it to need to restart its cooling process to restore the original refrigeration temperature after the door is closed, thus increasing energy consumption and wasting energy.

[0082] To address the above issues, some related technologies involve installing sensors on the outside of the refrigerator to detect vibration signals such as touch or knocking, thereby triggering the door to open. However, this sensor-based electronic triggering structure is complex, and the high cost of inductors significantly increases the refrigerator's production cost. In practical applications, this electronic triggering structure has low accuracy in identifying genuine "door open" signals, making judgment difficult and frequently resulting in false door openings. This leads to increased cold air leakage and energy consumption, resulting in poor actual performance.

[0083] Therefore, the applicant has painstakingly researched and designed a novel assisted door opening structure, breaking away from the conventional thinking of industry professionals (who traditionally use door handles or electronically controlled triggering structures to achieve assisted door opening). The applicant creatively proposes a refrigerator with assisted door opening functionality, employing a purely mechanical structure involving the coordination of components to achieve this triggering action. This effectively eliminates the low accuracy of the trigger signal detection inherent in electronically controlled triggering structures, which often leads to accidental door opening. It allows users to release their hands and use other parts of their body, such as their elbows or legs, to open the door, thus solving the problem of traditional refrigerators requiring manual opening, making it difficult to open when both hands are occupied. A detailed explanation follows.

[0084] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The refrigerator includes a cabinet 1 and a door 2.

[0085] The box body 1 is provided with a door-assisting structure 100, which includes at least a push plate 3 and a trigger plate 4. The push plate 3 and the trigger plate 4 are arranged opposite to each other and close to each other, so that the various components provided on the push plate 3 and the trigger plate 4 can be interlocked and cooperate with each other.

[0086] The push plate 3 is provided with a slider 31 that can rotate and move synchronously with the push plate 3. This can be understood as the slider 31 having a central axis connected to the push plate, and the slider 31 being able to rotate around the central axis.

[0087] The push plate 3 is connected with a first elastic member 32, which can be preferably a spring. The first elastic member 32 is used to drive the push plate 3 to move in the first direction F1 in the case of resetting, or to compress the first elastic member 32 to make the push plate 3 move in the second direction F2 when the push plate 3 is pushed by external force. In the embodiment, as shown in Figure 3 , the first direction F1 is the opening direction of the door body 2; the second direction F2 can be understood as the opposite direction of the first direction F1, as shown in Figure 5 .

[0088] Please refer to Figure 4 and Figure 5 , the trigger plate 4 is provided with a sliding rail 41 and a trigger protrusion 42 for driving the sliding block 31 to rotate. The trigger protrusion 42 is arranged opposite to the entrance 410 of the sliding rail 41. In this way, with the opening action, the sliding block 31 on the push plate 3 can move into the sliding rail 41 or between the entrance 410 of the sliding rail 41 and the trigger protrusion 42.

[0089] The sliding block 31 is arranged to have a first posture and a second posture switched by rotation, wherein, as shown in Figure 6 , the sliding block 31 can be stopped on the entrance 410 of the sliding rail 41 in the first posture; as shown in Figure 5 , the sliding block 31 can smoothly enter the sliding rail 41 from the entrance 410 of the sliding rail 41 and move in the first direction F1 in the second posture.

[0090] Please refer to Figure 1 , Figure 3 and Figure 5 , the door body 2 is provided with a movable block 5 for triggering by external force (such as parts of the human body, such as feet, elbows, etc. touching), which is used to push the above-mentioned push plate 3 in the case of being triggered by external force, so as to drive the sliding block 31 to move to the trigger protrusion 42, so that the sliding block 31 rotates to switch the posture, thereby realizing the limitation or release of the extension stroke of the push plate 3.

[0091] Compared with the prior art, the refrigerator provided by the embodiment of the application is provided with a newly designed power-assisted door opening structure 100 in the box body 1 of the refrigerator, and a movable block 5 for triggering by external force (such as pressing operation) is arranged on the door body 2 of the refrigerator to trigger the power-assisted door opening structure 100 to realize power-assisted door opening.

[0092] Wherein, the assisting door opening structure 100 includes a push plate 3 and a trigger plate 4, and the components on the two plates can be embedded together and cooperate with each other. The user can use the parts on the body (such as the elbow, leg, etc.) to trigger the assisting door opening structure 100 on the box body 1 by pressing the movable block 5 on the door body 2, and use the movable block 5 to push the push plate 3 to move to the second direction F2, so that the sliding block 31 which is stuck at the entrance 410 of the sliding rail 41 moves to the trigger protrusion 42 of the trigger plate 4, and the sliding block 31 is driven by the trigger protrusion 42 to rotate to switch the posture. The sliding block 31 after switching the posture can smoothly slide into the sliding rail 41 to move, thereby releasing the restriction on the extension stroke of the push plate 3. The push plate 3 moves to the first direction F1 under the action of the first elastic member 32 to push the door body 2 open, thereby achieving the purpose of assisting door opening or semi-automatic door opening. The user can open the door by touching without using both hands, which effectively improves the user experience.

[0093] Compared with the structure in the related art which uses a sensor to sense external force to trigger the door opening, the performance requirement of the sensor for this structure is higher, and only expensive sensors can be selected, resulting in increased cost, otherwise the door body 2 is often opened due to false triggering. In the refrigerator of the embodiment of the present application, the movable block 5 on the door body 2 directly triggers the assisting door opening structure 100 on the box body 1, realizes a mechanical triggering structure of pure component cooperation and interaction, eliminates the false triggering of the sensor, effectively improves the stability and reliability of the triggering assisting door opening, and improves the accuracy of the triggering assisting door opening.

[0094] In addition, compared with the structure of using a motor to drive a gear to drive a rack rod to push the door, since the inside of the refrigerator is prone to moisture and is often in a cold environment, such an electric door opening structure is prone to water risk and is prone to failure due to the influence of low temperature environment, and has a short service life. The assisting door opening structure 100 provided in the embodiment of the present application uses the elastic force of the first elastic member 32 to drive the push plate 3 to directly push open the door body 2, and uses the rotation of the sliding block 31 to switch the posture, thereby limiting or unlocking the moving stroke of the push plate 3, thereby replacing the traditional electric door pushing and unlocking mode, effectively eliminating the water risk and the influence of the low temperature environment, thereby reducing the failure rate, and being conducive to prolonging the service life.

[0095] For the cooperation structure of the sliding block 31 and the trigger protrusion 42, in one embodiment of the present application, please refer to Figure 7 and Figure 8 The sliding block 31 is a rectangular block with a length greater than the length of the entrance 410 of the sliding rail 41, and the two short sides of the sliding block 31 are provided with triangular grooves 311 recessed to the middle part of the sliding block 31.

[0096] The top corner 421 on the trigger protrusion 42 is used to contact and cooperate with the slider 31. The top corner 421 can be inserted into the triangular groove 311 of the slider 31 or slide along the long side a of the slider 31 to drive the slider 31 to rotate and switch the posture.

[0097] In the embodiment, as shown in Figure 7 and Figure 8 , the slider 31 has two opposite long sides a and two opposite short sides, and the triangular groove 311 is symmetrically arranged on the two opposite short sides. The four corners of the slider 31 are all acute angles.

[0098] When the slider 31 contacts the trigger protrusion 42, with the rotation of the slider 31, the top corner 421 slides on the surface of any one corner of the slider 31. One side of the surface of the corner makes the top corner 421 slide into the triangular groove 311, and the other side makes the top corner 421 slide on the long side a of the slider 31.

[0099] Therefore, when the top corner 421 is inserted into the triangular groove 311 of the slider 31, the slider 31 is rotated to switch to the first posture, and when the slider 31 moves towards the slide rail 41, the long side a of the slider 31 is stopped on the entrance 410 of the slide rail 41, so that the push plate 3 is retracted into the box 1. When the top corner 421 slides on the long side a of the slider 31, the slider 31 is rotated to switch to the second posture, and when the slider 31 moves towards the slide rail 41, the slider 31 can smoothly enter the slide rail 41 from the entrance 410 of the slide rail 41 and move along the slide rail 41, so that the push plate 3 can smoothly extend out of the box 1 to achieve power-assisted door opening.

[0100] Please refer to Figure 8 , the slide rail 41 is formed by two long strip ribs 411 on the trigger plate 4 extending along the length direction, and the interval between the two long strip ribs 411 near the same end of the trigger protrusion 42 forms the entrance 410 of the slide rail 41.

[0101] The top corner 421 on the trigger protrusion 42 is located opposite the entrance 410 of the slide rail 41 and within the projection range of the entrance 410, and the top corner 421 is offset from the central axis S between the two long strip ribs 411.

[0102] Therefore, when the slider 31 contacts the trigger protrusion 42, the top corner 421 on the trigger protrusion 42 can push the slider 31 to rotate along the outer contour of the slider 31, so that the slider 31 can switch the posture.

[0103] For the cooperation principle of the slider 31 and the trigger protrusion 42:

[0104] Please refer to Figure 6 , Figure 8 , Figure 9 ,Figure 10 and Figure 11 Firstly, the door body 2 is in a closed state, at this time, the sliding block 31 is in a first posture, is stuck on the entrance 410 of the sliding rail 41, the first elastic member 32 is contracted, and the push plate 3 is in a storage state. At this time, if the active block 5 triggers the push plate 3 to move the push plate 3 to the second direction F2, the push plate 3 drives the sliding block 31 to move to the trigger protrusion 42. As shown in Figure 8 , when the sliding block 31 contacts the trigger protrusion 42, the top corner 421 of the trigger protrusion 42 abuts on the sliding block 31 and slides along the long side a of the sliding block 31, so that the sliding block 31 rotates to switch to a second posture, as shown in Figure 9 , after the pressing force of the active block 5 disappears, the first elastic member 32 drives the push plate 3 to pop out in the door opening direction; as shown in Figure 10 and Figure 11 , after the sliding block 31 in the second posture smoothly enters the sliding rail 41 after the entrance 410 of the sliding rail 41 is possibly modified, and can move along the sliding rail 41 to the first direction F1, which means that the push plate 3 is released and the door body 2 is popped open, realizing power-assisted door opening.

[0105] Please refer to Figure 12 , Figure 13 , Figure 14 and Figure 15 , when the door body 2 is closed again, the push plate 3 will be driven to move to the second direction F2, and the sliding block 31 will move to the trigger protrusion 42 again; as shown in Figure 13 , when the sliding block 31 contacts the trigger protrusion 42, since the sliding block 31 is in the second posture, the triangular groove 311 on the sliding block 31 faces the top corner 421 of the trigger protrusion 42, and the top corner 421 will be clamped into the triangular groove 311 to drive the sliding block 31 to rotate and switch to the first posture; as shown in Figure 14 and Figure 15 , the sliding block 31 in the first posture is stuck on the entrance 410 of the sliding rail 41 by the setting that the long side a is greater than the entrance 410 of the sliding rail 41, so that the push plate 3 is reset.

[0106] It can be seen that the power-assisted door opening structure 100 of the embodiment of the application ingeniously uses the shape of the sliding block 31 to trigger the cooperation between the sliding block 31 and the top corner 421 of the trigger protrusion 42, so that the sliding block 31 rotates to switch the posture. The sliding block 31 can be stuck on the entrance 410 of the sliding rail 41 to realize the storage of the push plate 3, or the sliding block 31 can smoothly enter the sliding rail 41 to slide after switching the posture to realize the release of the push plate 3, effectively controlling the movement stroke of the push plate 3, thereby replacing the traditional electric control mode, being conducive to eliminating the risk of wading, having a simple structure, and reducing production cost.
