Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, specifically to a pull-out shelf structure for a freezer. Background Technology

[0002] In the field of refrigeration equipment, freezers typically employ shelving structures to utilize internal storage space in a layered manner. Most existing freezer pull-out shelving structures rely on direct shelf support, a simple and straightforward design that facilitates easy placement and retrieval of items, thus fulfilling the basic storage needs of freezers to a certain extent.

[0003] However, existing pull-out shelf structures for refrigerators, which rely on individual shelves for support, still have some drawbacks. When condensation forms on the surface of items placed on the shelves, or when liquid leaks, the water drips directly onto the bottom of the refrigerator, easily causing internal contamination and potentially leading to corrosion of the bottom components due to prolonged contact with water, affecting the refrigerator's lifespan and hygiene. Furthermore, during refrigerator use, especially when the door is opened and closed, the shelves tend to vibrate synchronously, causing the items on them to shake as well, affecting the stability of the stored items. Currently, there is an urgent need for a new type of pull-out shelf structure for refrigerators to address the problems of poor water retention and insufficient shelf installation stability in existing structures. Utility Model Content

[0004] The purpose of this application is to provide a pull-out shelf structure for a freezer to solve the problems of poor water and liquid retention and insufficient shelf installation stability in the existing pull-out shelf structures for freezers.

[0005] One aspect of this utility model provides a pull-out shelf structure for a freezer, including a freezer body and a storage cavity opened in the freezer body. The two inner sidewalls opposite to each other on the side of the storage cavity are provided with multiple positioning steps, and a shelf assembly is installed on each positioning step. The shelf assembly includes a side limiting member installed on the positioning step. The side limiting member includes two limiting steps formed inward along the extension direction of the positioning step. The first limiting step has a shelf placed on it, and the second limiting step has a water receiving tray placed on it. A limiting plate is provided at one end of the limiting step near the inside of the storage cavity.

[0006] In one embodiment, the inner sidewall is provided with multiple engaging slots, and the side limiting member is provided with engaging components on its side. The side limiting member is engaged and connected to the engaging slots through the engaging components.

[0007] In one embodiment, the engaging slots are located above the positioning steps and are symmetrically distributed on the inner sidewall, and the engaging components are symmetrically distributed on the side of the side limiting component.

[0008] In one embodiment, the shelf includes a support frame and support bars mounted on the support frame, with both ends of the support frame placed on the first-level limiting step.

[0009] In one embodiment, the support bar is a cylindrical structure.

[0010] In one embodiment, the support strips are spaced apart along the width of the support frame, and the storage cavity is also provided with multiple air vents located on the inner sidewall above the shelf.

[0011] In one embodiment, the freezer cabinet is further provided with a cold air transmission module. One end of the air vent is connected to the cold air output end of the cold air transmission module, and the other end is set towards the support area of ​​the shelf. The cold air transmission module is used to transport cold air, and the air vent is used to direct the cold air to the support area of ​​the shelf.

[0012] In one embodiment, the water receiving tray includes a water receiving trough and a support strip installed on the side of the water receiving trough, and the water receiving tray is placed on the second-level limiting step via the support strip.

[0013] In one embodiment, the support strip has rounded corners at its edges.

[0014] In one embodiment, the upper surface of the limiting step is provided with a reinforcing component.

[0015] Beneficial effects:

[0016] This utility model uses a shelf assembly consisting of a side limiting component, a shelf, and a water collection tray. Combined with the positioning steps and locking slots on the inner side wall of the storage cavity, the two-level steps of the side limiting component can support the shelf and the water collection tray respectively. The water collection tray catches condensate or leakage to prevent contamination inside the freezer and corrosion of components, thus solving the problem of poor water collection. At the same time, the double fixing of the locking structure and the positioning steps, along with the reinforcement of the limiting steps, restricts the lateral and longitudinal displacement of the shelf, thus solving the problem of insufficient installation stability. This utility model also achieves balanced force distribution on the side limiting parts by symmetrically arranging the locking slots above the positioning steps and correspondingly distributing the locking parts on the side limiting parts, thus preventing tilting and loosening. The locking structure also facilitates quick assembly and disassembly. Combined with the layered design of multiple locking slots and positioning steps, the shelf height adjustment range is refined, improving assembly efficiency and flexible utilization of storage space. This utility model also designs the storage rack as a combination structure of a load-bearing frame and cylindrical load-bearing strips. The cylindrical load-bearing strips reduce friction when taking items out and putting them in. The spaced load-bearing strips, together with the air vents above the storage rack that connect to the cold air transmission module, allow cold air to smoothly cover the items, thereby avoiding uneven local temperatures and accelerating the cooling of the items. This ensures that the temperature of each layer of the storage space is consistent, indirectly improving the refrigeration and preservation effect. In addition, the combined structure reduces the weight of the storage rack while ensuring load-bearing strength, thereby reducing the load-bearing pressure on the freezer body and the positioning steps. This utility model also designs the water receiving tray as a combination structure of water receiving groove and side support strip, and adapts the support strip to the second-level limiting step to provide stable support, thereby reducing the contact area between the water receiving tray and the step and thus reducing the risk of condensation sticking. The rounded corner structure design of the support strip edge eliminates sharp edges and avoids scratching operators during installation, disassembly or cleaning, thus improving the safety of use. This utility model also allows users to customize the installation position of the side limiting parts by pre-setting the number of positioning steps and different specifications of shelf components according to the size of the storage cavity. Users can also adjust the height of the storage space by disassembling the entire layer or removing the water tray separately to adapt to the storage needs of items of different sizes, further improving the flexibility of the shelf structure.

[0023] Please refer to Figures 1-4 One embodiment of this utility model provides a refrigerator pull-out shelf structure, including a refrigerator body 1 and a storage cavity 2 opened in the refrigerator body 1. The two inner sidewalls 6 opposite to each other on the side of the storage cavity 2 are provided with a plurality of positioning steps 3, and each positioning step 3 is equipped with a shelf assembly 4. The shelf assembly 4 includes a side limiting member 41 installed on the positioning step 3. The side limiting member 41 includes two limiting steps 42 formed inward along the extension direction of the positioning step 3. The first limiting step 42 is equipped with a shelf 43, and the second limiting step 42 is equipped with a water receiving tray 44. A limiting plate 45 is provided at one end of the limiting step 42 near the inside of the storage cavity 2.

[0024] It should be noted that in actual use, the side limiting member 41, the water receiving tray 44, and the shelf 43 can all be customized according to the user's own needs. Specifically, the storage cavity 2 has a pre-set positioning step 3. Taking two steps for each positioning step 3 as an example, the user can install the two limiting steps 42 on the side limiting member 41 onto the pre-set two limiting steps 42, and then place the shelf 43 and the water receiving tray 44 onto the side limiting member 41 accordingly. See Figure 1 The shelf assembly 4 divides the interior of the storage cavity 2 into five storage spaces of equal height. If the height of the placed items exceeds that of a single storage space, the user can remove the shelf assembly 4 located above it to provide a larger storage space height to accommodate the height of the placed items. If the user is certain that placing items will not cause condensation or liquid leakage, the water receiving tray 44 under the corresponding shelf 43 can also be removed to obtain a larger storage space below it. Nevertheless, the technical problem solved by this utility model includes solving the problem of poor water collection effect. The preferred embodiment is still that the shelf assembly 4 is used as a whole.

[0025] It should be further noted that, in actual use, the first-level limiting step 42 of the side limiting member 41 can provide upward support for the shelf 43, and in turn, together with the weight of the items placed on it, exert downward pressure on the shelf 43. The two work together to improve the stability of the shelf 43. The structure of the second-level step of the side limiting member 41 can limit and support the water tray 44, preventing the water tray 44 from swaying laterally. The degree of swaying of the water tray 44 can be reduced by lowering the height of the second-level step to the height of the connection between the water tray 44 and the second-level step, that is, lowering the height of the second-level step to the same height as the support bar 442 mentioned below. This design can limit the swaying space of the water tray 44 to between the stationary position and the bottom of the shelf 43, thereby reducing the degree of swaying of the water tray 44. Through the above design, the problem of insufficient stability of the shelf installation can be solved.

[0026] It should also be noted that in the actual design process, the upper surface of the limiting step 42 is usually provided with corresponding components or structures for anti-slip, increasing friction, or reinforcing the connection between the shelf 43 or water tray 44 and the limiting step 42. For example, anti-slip textures can be added to the first and second limiting steps 42, or fastening components or similar components can be added to the first limiting step 42 on the side limiting member 41, or fastening components or similar components can be added to the second limiting step 42. These can enhance the stability between the shelf 43 or water tray 44 and the limiting step 42, thereby further solving the problem of insufficient shelf installation stability.

[0027] It should be noted that the actual number of layers of the positioning steps 3 can be preset according to the size of the storage cavity 2. At the same time, side limiting parts 41, shelves 43 and water trays of different specifications are preset, allowing users to customize the installation position of the side positioning parts in the storage cavity 2 according to actual needs. This allows for further fine-tuning of the installation position of the shelf assembly 4 on the positioning steps 3 according to actual needs, thereby improving the installation flexibility of the shelf assembly 4.

[0028] In this embodiment, a shelf assembly 4 is provided, including a side limiting member 41, a shelf 43, and a drip tray 44. The side limiting member 41 forms two limiting steps 42 to support and limit the shelf 43 and the drip tray 44 respectively. On the one hand, the drip tray 44 can catch condensation or leakage from the items on the shelf 43, preventing water from dripping and contaminating the inside of the freezer or causing parts to rust. On the other hand, the first limiting step 42 of the side limiting member 41 provides stable support for the shelf 43 in conjunction with the weight of the items, and the second limiting step 42 restricts the lateral sway of the drip tray 44. At the same time, the longitudinal sway of the drip tray 44 can be limited by reducing the height of the second step. In addition, the addition of anti-slip textures, buckles, and other structures on the limiting step 42 further enhances the connection stability between the shelf 43 and the drip tray 44 and the limiting step 42. Additionally, the positioning steps 3 can be preset according to the size of the storage cavity 2, and can also be preset with side limiting parts 41, shelves 43 and water trays 44 of different specifications, allowing users to customize the installation position according to actual needs, which improves the installation flexibility of the shelf assembly 4 and can better adapt to the storage needs of items of different heights.

[0029] In one embodiment, the inner sidewall 6 is provided with a plurality of engaging slots, and the side limiting member 41 is provided with engaging member 411 on its side. The side limiting member 41 is engaged and connected to the engaging slots through the engaging member 411.

[0030] In one embodiment, the engaging slot (not shown) is located above the positioning step 3 and is symmetrically distributed on the inner sidewall 6, and the engaging member 411 is symmetrically distributed on the side of the side limiting member 41.

[0031] In this embodiment, by opening multiple locking slots on the inner sidewall 6 and providing a matching locking element 411 on the side of the side limiting element 41, the side limiting element 41 is connected to the locking slots through the locking element 411. Simultaneously, the locking slots are positioned above the positioning step 3 and symmetrically distributed with the locking element 411. On one hand, the locking connection structure and the supporting effect of the positioning step 3 form a double fixation, further limiting the lateral and longitudinal displacement of the side limiting element 41, preventing displacement of the side limiting element 41 due to vibrations from opening and closing the refrigerator door, thereby further improving the installation stability of the shelf 43 and the water tray 44. On the other hand, the symmetrically distributed locking slots and locking elements 411 ensure balanced force on the side limiting element 41, preventing tilting or loosening caused by unilateral force. Simultaneously, the locking connection structure facilitates the quick installation and removal of the side limiting element 41, avoiding affecting the user's ability to adjust the position of the shelf assembly 4 according to needs, and improving overall assembly efficiency. In addition, the multiple locking slots provide more installation position options for the side limiting component 41. Combined with the layered design of the positioning steps 3, the height adjustment range of the shelf assembly 4 can be further refined, improving the flexible utilization of the freezer storage space.

[0032] In one embodiment, the shelf 43 includes a support frame 431 and a support strip 432 mounted on the support frame 431, with both ends of the support frame 431 placed on the first-level limiting step 42.

[0033] In one embodiment, the support bar 432 is a cylindrical structure.

[0034] In this embodiment, by adopting a shelf 43 structure that combines a support frame 431 and cylindrical support bars 432, and placing both ends of the support frame 431 on the first-level limiting step 42 of the side limiting member 41, the installation stability of the shelf 43 can be further enhanced by the appropriate placement of the support frame 431 and the first-level limiting step 42. Combined with the limiting effect of the side limiting member 41, the shelf 43 is prevented from shifting laterally during use of the freezer. On the other hand, the smooth surface of the cylindrical structure can reduce the frictional resistance between the items and the support bars 432, making it convenient for users to quickly pick up and put down items. At the same time, the combination structure of the support frame 431 and the support bars 432 can reduce the overall weight while ensuring the load-bearing strength of the shelf 43, thereby reducing the load-bearing pressure on the freezer body 1 and the positioning steps 3. Furthermore, the spacing design between the support bars 432 will not obstruct the circulation of cold air inside the freezer, ensuring uniform temperature in the storage space and indirectly improving the refrigeration and preservation effect of the freezer.

[0035] In one embodiment, the support strips 432 are spaced apart along the width direction of the support frame 431, and the storage cavity 2 is also provided with a plurality of air vents 5, which are located on the inner side wall 6 above the shelf 43.

[0036] In one embodiment, the freezer body 1 is further provided with a cold air transmission module (not shown). One end of the air vent 5 is connected to the cold air output end of the cold air transmission module (not shown), and the other end is set toward the bearing area of ​​the shelf 43. The cold air transmission module (not shown) is used to transport cold air, and the air vent 5 is used to direct the cold air to the bearing area of ​​the shelf 43.

[0037] It should be noted that the cold air transmission module (not shown) of the freezer usually includes components such as a fan and air duct. The fan provides the air supply power, agitates the cold air generated by the evaporator, and delivers it to various areas inside the freezer body 1 through the air duct to achieve the cooling function. The specific structure of the cold air transmission module (not shown) will not be described in detail here.

[0038] In this embodiment, by distributing the support strips 432 at intervals along the width of the support frame 431, and providing multiple air vents 5 above the shelf 43 in the storage cavity 2, and connecting the air vents 5 to the cold air transmission module (not shown) in the freezer body 1, the spaced distribution structure of the support strips 432 can be used to reserve channels for cold air circulation. Combined with the upper air vents 5 and the connected cold air transmission module (not shown), this allows cold air to more smoothly cover the items on the shelf 43, avoiding uneven local temperatures caused by obstruction of the support structure and improving the temperature uniformity inside the freezer. On the other hand... With the help of the air transmission module (not shown), the surface can accurately deliver cold air to the shelf 43 area through the air guide 5, which can accelerate the cooling speed of the items and further optimize the refrigeration efficiency of the freezer. At the same time, the spaced distribution of the support strips 432 does not affect the stable support of the shelf 43 on the items, and can reduce the contact area between the support structure and the items, reducing the probability of local temperature differences caused by the items contacting the support strips 432. At the same time, the air guide 5 is set above the shelf 43, which allows the cold air to naturally penetrate downwards, ensuring that the temperature of each layer of the storage space is consistent, and indirectly improving the preservation effect of the items.

[0039] In one embodiment, the water receiving tray 44 includes a water receiving trough 441 and a support strip 442 installed on the side of the water receiving trough 441. The water receiving tray 44 is placed on the second-level limiting step 42 by the support strip 442.

[0040] In one embodiment, the support bar 442 has a rounded corner structure at its edge.

[0041] In this embodiment, the water receiving tray 44 is designed as a combination of a water receiving trough 441 and a side support strip 442. The water receiving tray 44 is placed on the second-level limiting step 42 via the support strip 442. A rounded corner structure is provided at the edge of the support strip 442. On the one hand, the matching placement of the support strip 442 and the second-level limiting step 42 provides stable support for the water receiving tray 44, preventing uneven force distribution caused by direct contact between the water receiving tray 44 and the limiting step 42. On the other hand, the rounded corner design of the support strip 442 eliminates sharp edges, preventing scratches to operators during installation, disassembly, or cleaning of the water receiving tray 44, thus improving safety. Simultaneously, the combination of the water receiving trough 441 and the support strip 442 ensures that the water receiving trough 441 has sufficient space to collect water, while the support strip 442 reduces the contact area between the water receiving tray 44 and the limiting step 42, lowering the risk of component adhesion due to condensate residue.

[0042] In one embodiment, a reinforcing component (not shown) is provided on the upper surface of the limiting step 42.

[0043] It should be noted that the reinforcing component (not shown) may be a component or structural design that can reinforce the connection between the shelf 43 and the drip tray and the limiting platform. For example, anti-slip texture may be added to the first limiting step 42 and the second limiting step 42, or a buckle component or similar component may be added to the first limiting step 42 on the side limiting member 41 and the second limiting step 42.

[0044] In this embodiment, by providing a reinforcing component (not shown) on the upper surface of the limiting step 42, the connection strength between the limiting step 42 and the shelf 43 and the water tray 44 can be enhanced by the reinforcing component (not shown), thereby enhancing the connection stability between the shelf 43 and the water tray 44 and the limiting step 42.

[0045] The overall working principle of this utility model is explained below: First, perform the basic assembly of the freezer shelves. Based on the number of pre-set positioning steps 3 on the inner wall 6 of the freezer storage cavity 2, select appropriate side limiting parts 41, shelves 43, and drip trays 44. First, align the locking parts 411 on the side of the side limiting parts 41 with the locking slots above the positioning steps 3, and press them to make the locking parts 411 engage with the locking slots. At the same time, the bottom of the side limiting parts 41 should fit against the surface of the positioning steps 3, forming a double fixation of locking and support, ensuring that the side limiting parts 41 are symmetrically distributed on the inner wall 6 of the storage cavity 2 and are not loose. Subsequently, the two ends of the support frame 431 of the shelf 43 are placed on the first-level limiting step 42 of the side limiting member 41. Utilizing the supporting effect of the first-level limiting step 42 and the lateral blocking of the limiting plate 45, along with the reinforcing components (not shown) on the upper surface of the limiting step 42, such as anti-slip textures or buckles, the friction between the shelf 43 and the limiting step 42 is increased or a tight fixation is achieved, preventing the shelf 43 from shifting laterally. Finally, the water receiving tray 44 is placed on the second-level limiting step 42 via the side support strip 442. The support strip 442 fits snugly against the second-level limiting step 42, and the height of the second-level limiting step 42 is equal to that of the support strip 442, limiting the longitudinal swaying space of the water receiving tray 44, thus completing the overall installation of the shelf assembly 4.

[0046] If the user needs to adjust the height of the storage space, the corresponding shelf component 4 can be disassembled according to the height requirements of the items. If the height of the items exceeds that of a single storage space, simply pry the side limiting piece 41 upwards to disengage the locking piece 411 from the locking slot, and remove the side limiting piece 41, shelf 43, and drip tray 44 of that layer to open up the adjacent storage spaces above and below, forming a higher storage area. If it is confirmed that there is no risk of condensation or leakage when placing items, the drip tray 44 can be lifted upwards separately to disengage the support strip 442 from the second limiting step 42, and the drip tray 44 can be removed to increase the height of the storage space below, adapting to different usage scenarios.

[0047] During normal operation of the freezer, the shelf structure simultaneously performs storage, liquid reception, and cold air adaptation functions. On one hand, the shelf 43 supports items through a combination of a support frame 431 and cylindrical support bars 432. The smooth surface of the cylindrical support bars 432 reduces friction when taking items out and putting them in. At the same time, the support bars 432 are spaced along the width of the support frame 431, reserving channels for cold air circulation. The cold air transmission module (not shown) in the freezer body 1 delivers cold air. The cold air is precisely blown onto the shelf 43 area through the air guide 5 above the storage cavity 2. It penetrates downwards through the spaced channels of the support bars 432, evenly covering the items on the shelf 43, avoiding uneven local temperatures. At the same time, the cold air absorbs heat from the items during circulation, maintaining a low-temperature environment in the storage space and achieving refrigeration and preservation.

[0048] On the other hand, when condensation occurs on the items on the shelf 43 or when liquid leakage occurs, the water drips along the gaps in the support strip 432 into the water collection tray 44 below. The cavity structure of the water collection tray 441 collects the water, preventing it from dripping directly onto the bottom of the freezer and causing contamination or corrosion of components. If the water collection tray 44 needs to be cleaned, it can be removed directly to empty the water. The rounded corner design of the support strip 442 prevents scratches to the operator during cleaning. After cleaning, it can be placed back into the second-level limiting step 42 for reuse.

[0049] If the shelves shift slightly during long-term operation of the freezer, the locking structure of the side limiting component 41, the reinforcing component (not shown) of the limiting step 42, and the limiting plate 45 will provide multiple layers of protection. The tight fit between the locking component 411 and the locking slot restricts the longitudinal displacement of the side limiting component 41, the positioning step 3 supports and prevents the side limiting component 41 from sinking, and the reinforcing component (not shown) prevents the shelf 43 and the water tray 44 from sliding relative to the limiting step 42, ensuring that the shelf structure always remains stable and continues to perform its functions of storage, water collection, and cold air circulation, completing a full cycle of installation, adjustment, use, and maintenance.

[0050] Beneficial effects:

[0051] This utility model uses a shelf assembly 4 consisting of a side limiting member 41, a shelf 43, and a water collection tray 44. With the positioning step 3 and locking slot on the inner side wall 6 of the storage cavity 2, the two steps of the side limiting member 41 can support the shelf 43 and the water collection tray 44 respectively. The water collection tray 44 collects condensate or leakage to prevent internal contamination and component corrosion of the freezer, thus solving the problem of poor water collection. At the same time, the double fixing of the locking structure and the positioning step 3, and the reinforcement component of the limiting step 42 (not shown) restrict the lateral and longitudinal displacement of the shelf, thus solving the problem of insufficient installation stability. This utility model also arranges the locking slots symmetrically above the positioning step 3 and the locking parts 411 are correspondingly distributed on the side of the side limiting parts 41, which can make the side limiting parts 41 bear the force evenly to avoid tilting and loosening. The locking structure is also easy to assemble and disassemble quickly. With the multiple locking slots and the layered design of the positioning step 3, the shelf height adjustment range is refined, and the assembly efficiency and storage space utilization rate are improved. This utility model also designs the shelf 43 as a combination structure of a support frame 431 and a cylindrical support bar 432. The cylindrical support bar 432 reduces friction when taking items out and putting them in. The spaced support bars 432, together with the air vent 5 above the shelf 43 that connects to the cold air transmission module (not shown), allow the cold air to smoothly cover the items, so as to avoid uneven local temperature and accelerate the cooling of the items, ensuring that the temperature of each layer of the storage space is consistent, indirectly improving the refrigeration and preservation effect. In addition, the combined structure reduces the weight of the shelf 43 while ensuring the load-bearing strength, reducing the load-bearing pressure on the freezer body 1 and the positioning steps 3. This utility model also designs the water receiving tray 44 as a combination structure of water receiving groove 441 and side support strip 442, and adapts the support strip 442 to the second-level limiting step 42 to provide stable support, thereby reducing the contact area between the water receiving tray 44 and the step and thus reducing the risk of condensate sticking. The rounded corner structure design of the support strip 442 eliminates sharp edges and prevents scratches to operators during installation, disassembly or cleaning, thus improving the safety of use. This utility model also allows users to customize the installation position of the side limiting piece 41 by pre-setting the number of positioning steps 3 and different specifications of shelf components 4 according to the size of the storage cavity 2, and adjust the height of the storage space by disassembling the entire layer component or removing the water tray 44 separately to adapt to the storage needs of items of different sizes, thereby further improving the flexibility of the shelf structure.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
