Description

Technical Field

[0001] The present invention relates to the field of refrigerators, in particular to a refrigerator and a ventilation grille assembly thereof. Background Art

[0002] Existing free-standing built-in refrigerators have kick-out legs at the bottom to achieve better integration with cabinets. However, these legs can affect heat dissipation. To enhance ventilation between built-in refrigerators and the outside environment, existing technologies often incorporate ventilation grilles at the bottom of the refrigerator. These grilles are connected to the refrigerator (or surrounding cabinets) through fastening or welding, making installation and removal inconvenient for users. Summary of the Invention

[0003] An object of the present invention is to overcome at least one drawback in the prior art and provide a refrigerator and a ventilation grille assembly thereof.

[0004] A further object of the present invention is to restrict the grille plate from separating from the skirting board from the back to the front, to ensure good stability among the box body, the skirting board and the grille plate, and to facilitate user disassembly.

[0005] Another further object of the present invention is to ensure that the grille plate and the skirting board are in a flush state when the limiting portion abuts against the skirting board.

[0006] In particular, the present invention provides a ventilation grille assembly for a refrigerator, the refrigerator includes a box body, and a skirting board is provided at the front bottom of the box body. The ventilation grille assembly includes: a grille plate, which is installed on the skirting board; a plurality of limiting portions, each limiting portion is formed on the grille plate, and the limiting portion has an abutment surface located on the rear side of the grille plate. The limiting portions are configured so that when the grille plate and the skirting board are in a flush state, the abutment surface abuts against the rear side of the skirting board to limit the grille plate from disengaging from the skirting board from the back to the front.

[0007] Optionally, each limiting portion includes: a first flange formed at the upper edge of the grille plate and extending toward the rear; a second flange formed at the end of the first flange and extending upward; a third flange formed at the end of the second flange and extending forward, and the end of the third flange is located on the rear side of the top edge of the grille plate, and the abutment surface is formed at the end of the third flange.

[0008] Optionally, the ventilation grille assembly also includes: a fourth flange, which is formed at the side edge of the grille plate and extends rearward and toward the lateral center of the grille plate; and a snap-fit ​​protrusion, which is formed on the fourth flange facing away from the surface of the grille plate, and the snap-fit ​​protrusion is configured such that when the grille plate is flush with the skirting board, the snap-fit ​​protrusion abuts against the rear side of the skirting board.

[0009] Optionally, the snap-fit ​​protrusion is configured as a portion of the fourth flange that is cut and then folded away from the grid plate.

[0010] Optionally, the ventilation grille assembly also includes: a fifth flange, formed at the end of the fourth flange and extending backward, and the fifth flange is also configured so that when the grille plate is flush with the skirting board, its end abuts against the front bottom surface of the box body, so as to jointly constrain the freedom of the grille plate in the front and rear directions with the limiting portion.

[0011] Optionally, the ventilation grille assembly also includes: a resistance portion, which is arranged at the top of the grille plate and includes: a sixth flange, formed at the upper edge of the grille plate and extending toward the rear; a seventh flange, formed at the end of the sixth flange and extending downward; and the resistance portion is configured so that when the grille plate is flush with the skirting board, the end of the seventh flange is in contact with the front bottom surface of the box body, so as to jointly constrain the freedom of the grille plate in the front and rear directions with the limiting portion.

[0012] Optionally, the ventilation grille assembly further includes: a plurality of magnets, which are arranged on the rear side of the grille plate to adsorb the grille plate to the front bottom of the box body.

[0013] Optionally, the rear side of the grid plate is provided with support ribs corresponding to the plurality of magnets one by one, and the support ribs and the first flange constrain the freedom of the magnets in the height direction.

[0014] Optionally, the grille plate has a plurality of ventilation holes distributed in an array; and the supporting ribs are formed at the edges of the ventilation holes at the highest layer and extend backward.

[0015] In particular, the present invention provides a refrigerator characterized by comprising the ventilation grille assembly according to any one of claims 1 to 9.

[0016] The ventilation grille assembly of the present invention has a plurality of stoppers disposed on the rear side of the grille plate. Therefore, when installing the grille plate, the grille plate can be pushed from front to rear toward the front lower portion of the housing, ultimately connecting to the housing. At this point, the grille plate is flush with the skirting board, and the stoppers on the rear side of the grille plate contact the rear side of the skirting board. The mutual restraint between the skirting board and the stoppers prevents the grille plate from being separated from the skirting board from rear to front, thereby ensuring good stability among the housing, skirting board, and the grille plate. Furthermore, the use of multiple stoppers contacting the skirting board replaces traditional screwing and welding methods, facilitating disassembly while reducing the number of parts and economic costs.

[0017] Furthermore, in the ventilation grille assembly of the present invention, a first flange is formed at the upper edge of the grille plate and extends toward the rear. A second flange is formed at the end of the first flange and extends upward. A third flange is formed at the end of the second flange and extends forward, and the end of the third flange is at the rear side of the top edge of the grille plate. An abutment surface is formed at the end of the third flange, that is, the end of the third flange needs to be slightly retracted from the top edge of the grille plate to avoid the thickness of the skirting board. In this way, when the edge of the grille plate is in contact with the edge of the preset area of ​​the skirting board and the two are in a flush state, the abutment surface formed at the end of the third flange can just abut against the rear surface of the skirting board, so that the grille plate will not be pushed backward by the third flange, thereby avoiding the occurrence of flash gaps between the skirting board and the grille plate, which is uneven and unsightly.

[0025] In the description of this embodiment, it should be understood that the terms "longitudinal," "transverse," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "depth," and the like, indicating orientations or positions, are based on the orientations in normal use and can be determined with reference to the orientations or positions shown in the accompanying drawings. For example, "front" in an orientation refers to the side facing the user. This is merely for the convenience of describing the present invention and to simplify the description. It does not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, it should not be construed as limiting the present invention.

[0026] See also Figure 1 and Figure 2 , Figure 1 1 is a schematic diagram of a refrigerator 1 according to an embodiment of the present invention, which shows a usage scenario in which the refrigerator 1 is embedded in a cabinet 2. Figure 2 1 is an exploded view of some components of a refrigerator 1 according to an embodiment of the present invention.

[0027] The present invention provides a refrigerator 1, which can be used alone or as a built-in refrigerator 1 (such as Figure 1 Generally, the refrigerator 1 may include a body 10 and a door 20.

[0028] The housing 10 includes an outer shell and multiple inner containers. The outer shell is located at the outermost side of the refrigerator 1 to protect the entire refrigerator 1. The multiple inner containers are enclosed by the outer shell, and the spaces between the multiple inner containers and the outer shell are filled with insulation material (forming a foam layer) to reduce heat dissipation from the inner containers. Each inner container defines a forward-opening storage space, which can be configured as a refrigerator, freezer, or temperature-controlled room, etc. The specific number and function of the storage space can be configured according to pre-determined requirements.

[0029] The number of doors 20 may also be the same as the number of inner containers, that is, each storage compartment open to the front of the inner container can be opened and closed by its corresponding door 20. The door 20 is movably arranged in front of the box body 10. For example, the door 20 can be hinged to one side of the front of the box body 10 to open and close the storage space by pivoting.

[0030] Typically, a compressor cabin is provided below the rear side of the housing 10, in which the compressor and condenser of the refrigerator 1 are provided. A cooling fan is also provided in the compressor cabin to draw in air from the external environment and to dissipate heat from the compressor and condenser in the compressor cabin.

[0031] Because the lowermost door 20 cannot completely cover the front bottom of the box body 10, and because the bottom foot 14 supports it, the bottom space 12 between the bottom plate and the bottom surface of the box body 10 is also open forward. Therefore, in order to conceal the ugliness and maintain a consistent style with the use scenario of the refrigerator 1, a skirting board 3 is provided at the front bottom of the refrigerator 1 for decoration. However, the installation of the skirting board 3 may block the heat dissipation airflow of the compressor compartment, affecting the heat dissipation efficiency of the refrigerator 1.

[0032] In some embodiments, the refrigerator 1 may further include a ventilation grille assembly 30, which is used to be installed below the front side of the body 10 of the refrigerator 1 to connect the bottom space 12 of the body 10 with the external environment to improve the heat dissipation efficiency of the refrigerator 1.

[0033] See also Figures 2 to 4 , Figure 3 FIG. 1 is a schematic diagram of a grille plate 310 of a ventilation grille assembly 30 according to an embodiment of the present invention, showing the rear side of the grille plate 310 . Figure 4 1 is a schematic diagram of the assembly relationship among the ventilation grille assembly 30, the box body 10, the door body 20 and the skirting board 3 according to one embodiment of the present invention.

[0034] The ventilation grille assembly 30 may further include a grille plate 310 and a plurality of stoppers 400. The grille plate 310 is mounted on the skirting board 3. Each stopper 400 is formed on the grille plate 310 and has an abutment surface 432 located on the rear side of the grille plate 310. The stoppers 400 are configured such that when the grille plate 310 and the skirting board 3 are flush, the abutment surface 432 abuts against the rear side of the skirting board 3, thereby preventing the grille plate 310 from separating from the skirting board 3 from the rear to the front.

[0035] Specifically, a plurality of ventilation holes 314a may be formed on the grille plate 310, and the grille plate 310 may be connected to the front bottom of the box body 10, so that at least some of the ventilation holes 314a thereon face the bottom space 12 between the bottom plate of the box body 10 and the ground, so that the ventilation holes 314a can be used to connect the bottom space 12 with the external environment and exchange heat with the external environment.

[0036] The skirting board 3 can cover the front lower part of the box body 10 laterally to shield the box body 10 below the refrigerator 1 and the bottom space 12 between the box body 10 and the ground, and be integrated with the surrounding cabinets 2 to form a unified decoration style.

[0037] In addition, in order to better integrate the skirting board 3 with the grille plate 310, the skirting board 3 can be provided with a preset area 3a for accommodating the ventilation grille at the bottom of the front side of the refrigerator 1. When the grille plate 310 is installed on the box body 10, the grille plate 310 is in the preset area 3a (such as Figure 2 shown).

[0038] In this embodiment, the grille plate 310 is further provided with a plurality of stoppers 400, which can be located on the rear side of the grille plate 310. When installing the grille plate 310, it can be pushed from front to back toward the front lower portion of the housing 10, ultimately attaching it to the housing 10. At this point, the grille plate 310 is flush with the skirting board 3, and the stoppers 400 on the rear side of the grille plate 310 contact the rear side of the skirting board 3, completing the installation. After installation, the restraint between the skirting board 3 and the stoppers 400 prevents the grille plate 310 from being separated from the skirting board 3 from the rear to the front, ensuring good stability among the housing 10, the skirting board 3, and the grille plate 310.

[0039] In addition, the method of using multiple limiting parts 400 to interfere with the skirting board 3 can replace traditional screw connection, welding and other methods, which not only makes disassembly convenient, but also reduces the number of parts and economic costs.

[0040] See also Figure 3 and Figure 4 Furthermore, each limiting portion 400 further includes a first flange 410, a second flange 420, and a third flange 430. The first flange 410 is formed at the upper edge of the grille plate 310 and extends rearward. The second flange 420 is formed at the end of the first flange 410 and extends upward. The third flange 430 is formed at the end of the second flange 420 and extends forward. The end of the third flange 430 is located behind the top edge of the grille plate 310, and an abutment surface 432 is formed at the end of the third flange 430.

[0041] In this embodiment, the first flange 410 , the second flange 420 and the third flange 430 can be integrally formed on the grid plate 310 by stamping, so that the connection between the first limiting portion 400 and the grid plate 310 is more secure.

[0042] Since the grille plate 310 and the skirting board 3 are both plate-shaped, and considering the thickness of the skirting board 3, the end of the third flange 430 needs to be set on the rear side of the top edge of the grille plate 310, that is, the end of the third flange 430 needs to be slightly retracted from the top edge of the grille plate 310 to avoid the thickness of the skirting board 3. In this way, when the edge of the grille plate 310 is connected to the edge of the preset area 3a of the skirting board 3 and the two are in a flush state, the abutment surface 432 formed at the end of the third flange 430 can just abut against the rear surface of the skirting board 3, so that the grille plate 310 will not be pushed backward by the third flange 430, thereby avoiding the occurrence of flash gaps between the skirting board 3 and the grille plate 310, which is uneven and unsightly.

[0043] In addition, the first limiting portion 400 may occupy the entire edge of the grid plate 310 or may occupy a portion of the edge of the grid plate 310. The number of the first limiting portion 400 may also be one or more, and when there are multiple first limiting portions 400, the multiple first limiting portions 400 may be arranged according to actual conditions. Figure 3 As shown, two first limiting portions 400 may be arranged on the top of the grid plate 310 at intervals in the transverse direction.

[0044] See also Figures 3 to 5 , Figure 5 2 is a diagram illustrating the structural relationship between the grille plate 310, the fourth flange 500, and the fifth flange 520 in the ventilation grille assembly 30 according to one embodiment of the present invention. In some embodiments, the ventilation grille assembly 30 may further include a fourth flange 500 and a snap-fit ​​protrusion 510. The fourth flange 500 is formed at a side edge of the grille plate 310 and extends rearward and toward the transverse center of the grille plate 310. The snap-fit ​​protrusion 510 is formed on the surface of the fourth flange 500 facing away from the grille plate 310. The snap-fit ​​protrusion 510 is configured to contact the rear side of the skirting board 3 when the grille plate 310 is flush with the skirting board 3.

[0045] In this embodiment, the number of fourth flanges 500 can be one or two. When there are two fourth flanges 500, the two fourth flanges 500 can be formed on the two lateral edges of the grille plate 310 and extend rearward. Correspondingly, the number of engaging protrusions 510 can also be set to two, and the two engaging protrusions 510 can be formed on the two fourth flanges 500. Of course, each fourth flange 500 can also be provided with more than one engaging protrusion 510, and can also be provided with two, three, or more, depending on actual circumstances.

[0046] Since the snap-fit ​​protrusion 510 is formed on the fourth flange 500 and protrudes away from the surface of the grille plate 310, when the grille plate 310 is pushed from front to back toward the box body 10, the snap-fit ​​protrusion 510 may be stuck on the front surface of the skirting board 3 due to being too protruding from the fourth flange 500, and it cannot be transitioned to the rear side of the skirting board 3, and then the grille plate 310 cannot be installed in the preset area 3a.

[0047] See also Figure 5In this embodiment, the fourth flange 500 can be configured to extend rearward and toward the transverse center of the grille plate 310. This allows the fourth flange 500 to be slightly retracted toward the transverse center of the grille plate 310, partially avoiding the position of the engaging protrusion 510 so that the engaging protrusion 510 does not protrude excessively from the fourth flange 500. (It should be noted that although the fourth flange 500 partially avoids the position of the engaging protrusion 510, the engaging protrusion 510 still naturally protrudes beyond the side edge of the grille plate 310 to contact the baseboard 3.) When the grille plate 310 is installed, the engaging protrusion 510 can smoothly transition to the rear side of the baseboard 3 through its own deformation.

[0048] See also Figure 5 Furthermore, the snap-fit ​​protrusion 510 is configured as a portion of the fourth flange 500 that is cut and then folded away from the grid plate 310 .

[0049] When making the snap-fit ​​protrusion 510, you can first use a cutting device to cut part of the plate body on the fourth flange 500, but a part needs to remain connected to the fourth flange 500 (for example, you can select a square area on the fourth flange 500, cut three sides of the square area, and retain one side), and then use a tool to push this part of the plate body out of the fourth flange 500 from the inside to the outside (away from the grid plate 310 is the outside, close to the grid plate 310 is the inside), forming a snap-fit ​​protrusion 510 that protrudes from the fourth flange 500 and away from the grid plate 310 in a natural state.

[0050] Furthermore, the engaging protrusion 510 can be configured to extend from rear to front and outward. This allows the rear end of the engaging protrusion 510 to reach the baseboard 3 first when the grille 310 is pushed from front to back toward the housing 10. Since the rear end is relatively low, it does not hinder the advancement of the grille 310. As the advancement continues, the engaging protrusion 510 gradually contacts the baseboard 3. Pressed inward by the baseboard 3, the engaging protrusion 510 retracts into the fourth flange 500, generating an elastic restoring force. Once the engaging protrusion 510 has completely passed through the baseboard 3, the elastic restoring force causes the engaging protrusion 510 to re-eject from the fourth flange 500, with its front end abutting the inner side of the baseboard 3.

[0051] See also Figures 3 to 5 Furthermore, the ventilation grille assembly 30 may further include a fifth flange 520. The fifth flange 520 is formed at the end of the fourth flange 500 and extends rearward. The fifth flange 520 is further configured such that when the grille plate 310 is flush with the skirting board 3, its end abuts against the front bottom surface of the box body 10, thereby jointly constraining the freedom of the grille plate 310 in the front-to-back direction with the limiting portion 400.

[0052] The number of fifth flanges 520 can correspond to the number of fourth flanges 500. The fifth flanges 520 are formed at the ends of the fourth flanges 500 and extend rearward, serving as guides for installing the grille plate 310. During installation of the grille plate 310, the fifth flanges 520 first enter the predetermined area 3a of the skirting board 3. Guided by the fifth flanges 520, the grille plate 310 can be installed onto the housing 10 in a front-to-back orientation as much as possible, mating with the skirting board 3.

[0053] When the grille plate 310 reaches the installation position, the end of the fifth flange 520 can abut against the box body 10, so that the grille plate 310 cannot move further backward, and then cooperate with the forward limiting function of the limiting portion 400 and the snap-on protrusion 510, so that the grille plate 310 is completely constrained in the front and rear directions, and has better stability.

[0054] See also Figure 3 and Figure 4 In some embodiments, the ventilation grille assembly 30 may further include a resisting portion 600, which is disposed at the top of the grille plate 310. The resisting portion 600 may further include a sixth flange 610 and a seventh flange 620. The sixth flange 610 is formed at the upper edge of the grille plate 310 and extends toward the rear. The seventh flange 620 is formed at the end of the sixth flange 610 and extends downward. The resisting portion 600 is configured such that when the grille plate 310 is flush with the skirting board 3, the end of the seventh flange 620 resists against the front bottom surface of the box body 10, so as to jointly constrain the freedom of the grille plate 310 in the front and rear directions with the limiting portion 400.

[0055] The number of the interference portion 600 can be one or more. Figure 4 As shown, when there is only one abutting portion 600, it can be disposed between the two limiting portions 400 and formed by cutting and stamping. When the grille plate 310 is flush with the skirting board 3, the end of the seventh flange 620 abuts against the front bottom surface of the box body 10, thereby preventing the top of the grille plate 310 from sinking backward.

[0056] See also Figures 2 to 4 In some embodiments, the ventilation grille assembly 30 may further include a plurality of magnets 320 . The plurality of magnets 320 are disposed on the rear side of the grille plate 310 to fix the grille plate 310 to the lower front side of the box body 10 .

[0057] Specifically, the grid plate 310 may include a connecting plate section 312 and an opening plate section 314 formed below the connecting plate section 312. Figure 3As shown in FIG. 3 , multiple ventilation holes 314a are formed in the perforated plate section 314. Multiple magnets 320 can be disposed on the rear side of the connecting plate section 312 to attract the connecting plate section 312 to the front bottom surface of the box body 10. This allows the perforated plate section 314 to naturally face the bottom space 12 between the bottom plate and the ground, and all ventilation holes 314a thereon face the bottom space 12, thereby improving ventilation.

[0058] Furthermore, the grille plate 310 (or at least the connecting plate section 312 of the grille plate 310) is made of a magnetic material (e.g., 430 stainless steel). Multiple magnets 320 are evenly spaced laterally on the rear side of the grille plate 310. These magnets 320 can attach the grille plate 310 to the housing 10 (or a sheet metal component of the housing 10), achieving a connection. Furthermore, the magnetic attachment method is simple to operate, making it easy for the user to install and remove.

[0059] See also Figure 3 and Figure 4 In some embodiments, the grille plate 310 further includes a plurality of support ribs 315, which are all arranged on the rear side of the grille plate 310, and the number of the support ribs 315 corresponds one-to-one to the number of the magnets 320, so as to support the magnets 320 and prevent the magnets 320 from being separated from their original positions due to their own gravity during long-term use, thereby preventing the grille plate 310 from being separated from the box body 10.

[0060] In this embodiment, the support rib 315 can be a rib protruding from the rear surface of the grille plate 310. It can be integrally formed with the grille plate 310, and can also be installed on the rear surface of the grille plate 310 by welding, clamping, riveting or other fixing methods.

[0061] In addition, the support ribs 315 can be set on the connecting plate section 312 of the grid plate 310 or on the perforated plate section 314 of the grid plate 310, as long as the magnet 320 can be supported on the rear side of the connecting plate section 312 of the grid plate 310.

[0062] The number of support ribs 315 corresponds to the number of magnets 320. For example, two magnets 320 are respectively arranged on the lateral sides of the connecting plate section 312. Then, correspondingly, there is a support rib 315 on each lateral side of the grid plate 310 to support the corresponding magnet 320.

[0063] See also Figure 3 and Figure 4 In some embodiments, the plurality of ventilation holes 314a are distributed in multiple layers in the height direction. Figure 3 and Figure 4As shown, multiple ventilation holes 314a are distributed in an array on the grid plate 310. The multiple ventilation holes 314a can be distributed in multiple layers along the height direction, with multiple ventilation holes 314a evenly distributed in each layer, and multiple ventilation holes 314a in each column are arranged sequentially along the height direction.

[0064] Of course, the plurality of ventilation holes 314a can also be arranged in other ways, such as staggered arrangement in the height direction, etc., as long as the opening plate section 314 of the grid plate 310 can be fully utilized and has a certain aesthetic appeal.

[0065] See also Figure 3 and Figure 4 Furthermore, support ribs 315 are formed at the edge of the highest ventilation hole 314a and extend rearward. Since the highest ventilation hole 314a is adjacent to the connecting plate section 312 of the grille plate 310, arranging the support ribs 315 at the edge of the highest ventilation hole 314a can meet the requirements for supporting the magnet 320.

[0066] In addition, since the support ribs 315 are formed at the edge of the ventilation holes 314a at the highest layer and extend backward, a stamping die can be used to quickly manufacture them during production. This not only eliminates the tedious installation process and reduces the number of parts, but also enables the connection with the grille plate 310 to be more firmly established.

[0067] Specifically, during the manufacturing process, the vent 314a where the support rib 315 is to be provided is first punched out. The area of ​​this vent 314a is smaller than that of the other vents 314a. The edges of this vent 314a are then punched from front to back using a stamping die, causing a portion of the edge to fold over and protrude from the rear surface of the grille plate 310. This not only forms the support rib 315 but also ensures that the area of ​​this vent 314a is consistent with that of the other vents 314a after the second punching process.

[0068] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
