Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator drawer assembly and a refrigerator. Background Technology

[0002] As an important component for storing food in a refrigerator, the design of refrigerator drawers directly affects the user experience. Traditional refrigerator drawers typically use a sliding mechanism to achieve their function, making it convenient for users to access or store items.

[0003] However, in actual use, when a user pulls out a drawer quickly, the items in the drawer may shake and collide with each other due to inertia, thus generating collision noise. Moreover, when the items are relatively scattered in the drawer, pulling out the drawer may also generate collision noise, affecting the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator drawer assembly and refrigerator that can prevent items from making collision noise when the drawer is pulled out.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator drawer assembly includes a slide rail and a drawer. The slide rail is installed inside the refrigerator and has an auxiliary surface. The drawer has a receiving cavity and slides into or out of the refrigerator relative to the slide rail in the depth direction. The outer side of the drawer has a sliding post that overlaps the auxiliary surface.

[0007] The auxiliary surface is set at a first angle to the horizontal plane, and at least a portion of the auxiliary surface gradually slopes upward relative to the horizontal plane in the height direction of the refrigerator along the sliding direction of the drawer; the bottom surface of the accommodating cavity is set at a second angle to the horizontal plane in the depth direction of the refrigerator, and the slope direction of the bottom surface is the same as the slope direction of the auxiliary surface.

[0008] Understandably, this application, by setting an auxiliary surface and positioning the bottom surface at a second angle to the horizontal plane, ensures that at least part of the drawer's travel is on an incline when it slides out, thus preventing excessively fast drawer exit and avoiding instability and noise caused by items inside the drawer shaking. Simultaneously, the incline of the bottom surface relative to the horizontal plane allows items inside the drawer to slide downwards along the slope during extraction, with the items positioned at the end of the drawer opposite the direction of exit. This effectively prevents gaps between items from causing them to shake and collide, generating noise. In other words, this application, through the design of the auxiliary surface and bottom surface, ensures that the items inside the drawer remain relatively stable when it slides out, reducing noise and improving the user experience.

[0009] In one embodiment, along the sliding direction of the drawer, the auxiliary surface includes a first surface, a second surface, and a third surface, the second surface forming the first angle with the horizontal plane, and the third surface being positioned higher than the first surface in the height direction of the refrigerator.

[0010] Understandably, by setting up the second side, the drawer can be subjected to resistance in the opposite direction of its sliding when it moves to that point, thus slowing down the speed at which the drawer slides out. It also allows all items inside the drawer to have an anti-inertial tendency in the same direction as the resistance, preventing excessive inertia from causing items to shake and collide, producing abnormal noises.

[0011] In one embodiment, a stop post is provided on the auxiliary surface, and when the drawer slides out of the preset position of the box, the stop post cooperates with the sliding post to stop it.

[0012] The auxiliary surface is provided with a deceleration pad at a position adjacent to the stop post, and the sliding post cooperates with the stop post via the deceleration pad.

[0013] Understandably, the stop bar is designed to work in conjunction with the sliding bar to prevent the drawer from being pulled out too far, detaching from the slide rail and falling, which could damage items. The deceleration pad slows down the drawer as it slides out and is about to reach the stop bar, thus preventing the sliding bar from suddenly hitting the stop bar and causing items inside the drawer to tip forward due to inertia. This further avoids damage to items or collision noise when items tip over.

[0014] In one embodiment, grooves are formed on the surface of the deceleration pad.

[0015] Understandably, the groove design increases the friction of the speed-reducing pad, further slowing down the drawer's sliding speed.

[0016] In one embodiment, the slide rail is provided with a slide groove, and the outer side of the drawer is also provided with a first roller, which is located within the slide groove and rolls in cooperation with the groove wall.

[0017] Understandably, by cooperating with the groove wall of the first roller, the frictional resistance between the drawer and the slide rail can be reduced, making the relative movement between the two smoother and effectively improving the user experience.

[0018] In one embodiment, the second included angle is configured as θ2, where 3°≤θ2≤5°.

[0019] Understandably, this angle range provides enough tilt angle for items to slide out of the drawer and naturally return to their original positions by gravity, while also preventing small items from rolling around or excessive waste of storage space due to an excessively large angle.

[0020] In one embodiment, the drawer includes a body and a tray. Along the depth direction of the refrigerator, a handle is provided at one end of the body. The receiving cavity is opened on the body, and the tray is located at the bottom of the body and connected to the body in the height direction of the refrigerator. The tray is slidably connected to the slide rail, and the sliding post is provided on the outer side of the body.

[0021] Understandably, the handle makes it easier for users to pull out the drawer, improving the convenience of using the drawer; and the tray prevents the body from directly contacting the drawer slide and causing scratches during movement, and makes it easier to remove the body from the drawer slide or install it on the drawer slide, further improving the convenience of use.

[0022] In one embodiment, the tray is configured as an assisting surface on the side of the refrigerator facing away from the main body in the height direction, and an inclined surface is provided at the end of the assisting surface near the handle in the depth direction of the refrigerator. The inclined surface is set at an angle to the horizontal plane, and the inclined direction of the inclined surface is the same as the inclined direction of the assisting surface.

[0023] The slide rail is provided with a second roller at one end near the handle, and the second roller can roll in cooperation with the inclined surface.

[0024] Understandably, by setting an inclined surface, the drawer can automatically move along the sliding direction under its own weight during the latter part of its slide-in journey using the cooperation of the inclined surface and the second roller. This eliminates the need for manual pushing of the drawer to achieve the self-locking function and ensures that the drawer will not fail to close properly.

[0025] In one embodiment, a third angle is formed between the inclined surface and the horizontal surface, the third angle being configured as θ3, where 4°≤θ2≤6°.

[0026] This application also provides a refrigerator, including the refrigerator drawer assembly described in any of the above embodiments.

[0027] Compared to existing technologies, this application, by setting an auxiliary surface and positioning the bottom surface at a second angle to the horizontal plane, ensures that at least part of the drawer's travel is on an incline when it slides out, thus preventing excessively fast drawer exit and avoiding instability and noise caused by items inside the drawer shaking. Simultaneously, the tilted bottom surface relative to the horizontal plane allows items inside the drawer to slide downwards along the slope during extraction, with the items positioned at the end of the drawer opposite the direction of exit. This effectively prevents gaps between items from causing them to shake and collide, generating noise. In other words, this application, through the design of the auxiliary surface and bottom surface, ensures that the items inside the drawer remain relatively stable when it slides out, reducing noise and improving the user experience.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0044] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0045] Please see Figure 1 and Figure 2 This application provides a refrigerator 200, which includes a cabinet 201, a door 202 and a refrigerator drawer assembly 100. The door 202 is installed on the cabinet 201 and can open or close the cabinet 201. The refrigerator drawer assembly 100 is located in the cabinet and is used to store food and other items and can facilitate users to take out or store items.

[0046] Specifically, such as Figures 2 to 8 As shown, the refrigerator drawer assembly 100 includes a slide rail 10 and a drawer 20. The slide rail 10 is installed inside the body 201 of the refrigerator 200, and an auxiliary surface 11 is provided on the slide rail 10. The drawer 20 has a receiving cavity 21, which slides and engages with the slide rail 10 and can slide into or out of the body 201 relative to the slide rail 10 in the depth direction x of the refrigerator 200. A sliding post 22 is provided on the outer side of the drawer 20, and the sliding post 22 overlaps on the auxiliary surface 11. The auxiliary surface 11 is set at a first angle with the horizontal plane, and at least a portion of the auxiliary surface 11 gradually tilts upward relative to the horizontal plane in the height direction z of the refrigerator 200 along the sliding direction of the drawer 20. The bottom surface 211 of the receiving cavity 21 in the depth direction x of the refrigerator 200 is set at a second angle with the horizontal plane, and the tilt direction of the bottom surface 211 is the same as the tilt direction of the auxiliary surface 11.

[0047] It should be explained that when the drawer 20 is pulled out, items may fall due to inertia and be damaged, or collide with each other, generating collision noise. This could not only injure the user but also cause damage or displacement of items, affecting the user experience. Therefore, this application sets up an auxiliary surface 11 and sets the bottom surface 211 at a second angle to the horizontal plane. In this way, the auxiliary surface 11 ensures that at least part of the drawer 20's travel is in an uphill state when it slides out, thus preventing the drawer 20 from sliding out too quickly, which would cause the items inside the drawer 20 to become unstable and shake, generating noise. At the same time, combined with the bottom surface 211 being tilted relative to the horizontal plane, the items inside the drawer 20 have a tendency to slide downwards along the slope during the pulling process, and the items are positioned at the end of the drawer opposite to the sliding direction. This effectively avoids gaps between items that could cause them to shake and collide, generating noise. In other words, by setting up the auxiliary surface 11 and the bottom surface 211, this application can ensure that the items inside the drawer 20 remain in a relatively stable state when the drawer 20 slides out, reducing noise generation and improving the user experience.

[0048] Here, in order to prevent fruits, vegetables and other odors from mixing with other odorous ingredients, the layout of the refrigerator 200 can be changed, and an independent compartment can be set up in the cabinet 201 to store fruits and vegetables and other items that may affect the user experience due to cross-contamination of odors. The refrigerator drawer assembly 100 in this application can be set up in multiple units in this independent compartment so that different types of fruits or vegetables can be stored separately.

[0049] Furthermore, an independent refrigeration system can be installed in this independent compartment. This involves attaching a plate-tube evaporator 203 to the inner liner of the casing 201 of the independent compartment and installing a fan 204. The temperature of the corresponding independent compartment is controlled by the radiant cooling energy from the plate-tube evaporator 203. Alternatively, the plate-tube evaporator 203 can be placed inside the casing 201, allowing the cooling energy generated by the plate-tube evaporator 203 to circulate directly through the fan 204 inside the air duct. Of these two independent refrigeration systems, the former is easier to manufacture and has lower costs, while the latter reduces frost buildup inside the casing 201. Specific installation methods can be customized according to actual needs and are not limited here.

[0050] It should be noted that the aforementioned independent compartments and independent refrigeration systems can be customized according to user needs, and are not the focus of this application, so they will not be elaborated on here. This application mainly improves the structure of the refrigerator drawer assembly 100 to keep the items inside the drawer 20 in a relatively stable state, thereby reducing noise during user operation. The following mainly describes the refrigerator drawer assembly 100.

[0051] like Figures 3 to 5As shown, along the sliding direction of drawer 20, the auxiliary surface 11 includes a first surface 111, a second surface 112, and a third surface 113. The second surface 112 forms a first angle with the horizontal plane, and in the height direction z of the refrigerator 200, the position of the third surface 113 is higher than the position of the first surface 111. Thus, when drawer 20 passes the first surface 111, its movement remains smooth, avoiding sudden uphill movements that could cause jamming or excessive resistance. Furthermore, the second surface provides resistance in the opposite direction of its sliding, slowing down the drawer's sliding speed and ensuring that all items inside the drawer have an anti-inertial tendency in the same direction as the resistance, preventing excessive inertia from causing items to shake, collide, or produce abnormal noise. Simultaneously, when passing the third surface 113, the drawer remains stable as it approaches full extension, preventing sudden drops or rebounds at the end. In short, the arrangement of the first surface 111, the second surface 112, and the third surface 113 makes the drawer's sliding smoother and more efficient, thereby improving the user experience.

[0052] Here, the direction in which drawer 20 slides out is consistent with the depth direction (x) of refrigerator 200.

[0053] Furthermore, a stop post 12 is provided on the auxiliary surface 11. When the drawer 20 slides out of the preset position relative to the box 201, the stop post 12 and the sliding post 22 engage in a stop-locking action. A deceleration pad 13 is provided on the auxiliary surface 11 near the stop post 12, and the sliding post 22 engages with the stop post 12 via the deceleration pad 13. Thus, the stop-locking action between the stop post 12 and the sliding post 22 prevents the drawer 20 from being pulled out excessively and falling off the slide rail 10, thus preventing damage to items. The deceleration pad 13 slows down the drawer 20 as it slides out and approaches the stop post 12, preventing the sliding post 22 from suddenly colliding with the stop post 12 and causing items inside the drawer to tip forward due to inertia, further preventing damage to items or collision noise during tipping.

[0054] Preferably, the surface of the speed reduction pad 13 is provided with a groove 131. It can be understood that the groove 131 can increase the friction performance of the speed reduction pad 13 and further reduce the speed at which the drawer 20 slides out.

[0055] Here, multiple grooves 131 can be provided, and the multiple grooves 131 are evenly distributed on the deceleration pad 13 to avoid the drawer 20 from getting stuck when it moves, while increasing the friction of the deceleration pad 13 on the drawer 20.

[0056] In one embodiment, the slide rail 10 is provided with a slide groove 14, and the outer side of the drawer 20 is also provided with a first roller 23. The first roller 23 is confined within the slide groove 14 and rolls in cooperation with the groove wall of the slide groove 14. In this way, the frictional resistance between the drawer 20 and the slide rail 10 can be reduced by the cooperation between the first roller 23 and the groove wall of the slide groove 14, making the relative movement between the two smoother and effectively improving the user experience.

[0057] Furthermore, a second roller 15 is also provided on the slide rail 10, so that the second roller 15 can roll in conjunction with the drawer 20, reducing the force required by the user when pulling out the drawer 20 and further improving the user experience.

[0058] like Figure 4 , Figure 7 and Figure 8 As shown, drawer 20 includes a body 24 and a tray 25. Along the depth x direction of the refrigerator 200, a handle 241 is provided at one end of the body 24. A receiving cavity 21 is formed on the body 24. The tray 25 is positioned at the bottom of the body 24 and connected to it along the height z direction of the refrigerator 200. The tray 25 is slidably connected to the slide rail 10, and a sliding post 22 is provided on the outer side of the body 24. It is understood that the handle 241 facilitates the user's pulling out of the drawer 20, improving the convenience of using the drawer 20. Furthermore, the tray 25 prevents the body 24 from directly contacting the slide rail 10, thus avoiding scratches during movement, and allows the body 24 to be easily removed from or installed on the slide rail, further enhancing ease of use.

[0059] Here, the second included angle between the bottom surface 211 of the accommodating cavity 21 and the horizontal plane is configured as θ2, where 3°≤θ2≤5°. It can be understood that this angle range provides sufficient tilt angle for items inside the drawer 20 to naturally return to their original positions by gravity when sliding out, while also preventing small items from rolling spontaneously or excessive waste of storage space due to an excessively large angle.

[0060] Furthermore, the value of θ2 can be 3°, 3.5°, 4°, 4.5°, or 5°. Of course, it is not limited to these values, and the specific value of θ2 can be determined according to the actual situation.

[0061] In one embodiment, the tray 25 is configured as an assist surface 251 on the side of the refrigerator 200 facing away from the body 24 in the height direction z. In the depth direction x of the refrigerator 200, an inclined surface 252 is provided at the end of the assist surface 251 near the handle 241. The inclined surface 252 is angled to the horizontal plane, and its inclination direction is the same as that of the auxiliary surface 11. The second roller 15 is located on the slide rail 10 near the handle 241 and rolls in cooperation with the inclined surface 252. This allows the drawer 20 to automatically move along its sliding direction under its own weight during the latter part of its slide into the cabinet 201, utilizing the cooperation of the inclined surface 252 and the second roller 15. This eliminates the need for manual pushing of the drawer 20 to achieve a self-locking function and ensures that the drawer 20 will not be left partially closed.

[0062] Furthermore, the inclined plane 252 forms a third included angle with the horizontal plane, and the third included angle is configured as θ3, where 4°≤θ2≤6°.

[0063] Here, θ3 can take values ​​of 4°, 4.5°, 5°, 5.5°, and 6°. Of course, it is not limited to these values, and the specific value of θ3 can be determined according to the actual situation.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
