Referring to fig. 2 to 5, fig. 3 is a schematic view of a grid plate 310 of a ventilation grid assembly 30 according to an embodiment of the present invention, which shows a front side of the grid plate 310, fig. 4 is a schematic view of a grid plate 310 of a ventilation grid assembly 30 according to an embodiment of the present invention, which shows a rear side of the grid plate 310 and support ribs 315 thereon, and fig. 5 is a schematic view of an assembly relationship between the ventilation grid assembly 30, a box 10, a door body 20 and a skirting board 3 according to an embodiment of the present invention.
The ventilation grille assembly 30 may also include a grille plate 310 and a plurality of magnets 320. The grill plate 310 is opened with a plurality of ventilation holes 314a. A plurality of magnets 320 are disposed at the rear side of the grating plate 310 to fix the grating plate 310 under the front side of the cabinet 10, so that at least some of the ventilation holes 314a face the bottom space 12 between the bottom plate of the cabinet 10 and the ground, so as to communicate the bottom space 12 with the external environment by using the ventilation holes 314a.
Specifically, the grid plate 310 may include a connection plate section 312 and an aperture plate section 314 formed below the connection plate section 312, with a plurality of vent holes 314a opening on the aperture plate section 314. When the plurality of magnets 320 are disposed at the rear side of the connection plate section 312 so that the connection plate section 312 is attracted to the front bottom surface of the cabinet 10, the perforated plate section 314 naturally faces the bottom space 12 between the bottom plate and the ground, and all the ventilation holes 314a thereon face the bottom space 12, so that the ventilation effect is better.
In the ventilation grille assembly 30 of the present embodiment, since the plurality of ventilation holes 314a of the perforated plate section 314 communicate the bottom space 12 with the external environment when the connecting plate section 312 of the grille plate 310 is fixed to the lower portion of the front side of the cabinet 10, the heat-dissipating airflow in the press compartment can exchange heat with the air in the external environment through the plurality of ventilation holes 314a.
For example, the heat dissipation of the compressor compartment may be performed by bottom heat dissipation. The bottom plate of the press cabin (i.e. the bottom plate of the box body 10) may be provided with heat dissipation holes, and the heat dissipation airflow in the press cabin may be firstly discharged downwards into the bottom environment between the bottom plate of the press cabin and the ground, and then be discharged forwards into the external environment through the plurality of ventilation holes 314a. Meanwhile, air in the external environment can also sequentially enter the press cabin through the plurality of vent holes 314a and the radiating holes on the bottom plate to form circulation with radiating airflow.
In addition, in the ventilation grille assembly 30 of the present embodiment, the connecting plate sections 312 of the grille plate 310 are magnetically connected to the housing 10. The grid plate 310 (or at least the connecting plate segments 312 of the grid plate 310) is made of a magnetic material (e.g., 430 stainless steel, etc.). The plurality of magnets 320 are uniformly disposed at the rear side of the grating plate 310 along the transverse direction, so that the plurality of magnets 320 can attach the grating plate 310 to the box body 10 (or the sheet metal part of the box body 10) to achieve connection. And, the mode easy operation of magnetism is inhaled, and the user of being convenient for installs and dismantles.
Referring to fig. 4 and 5, in some embodiments, the grid plate 310 further includes a plurality of support ribs 315, the plurality of support ribs 315 are disposed at the rear side of the grid plate 310, and the number of the support ribs 315 corresponds to the number of the magnets 320 one to one, so as to support the magnets 320, prevent the magnets 320 from being separated from the original position due to the self-gravity during the long-term use, and further prevent the grid plate 310 from being separated from the box body 10.
In this embodiment, the support rib 315 may be a rib protruding from the rear side surface of the grid plate 310, and may be integrally formed with the grid plate 310, and may also be mounted on the rear side surface of the grid plate 310 by welding, clamping, riveting, or other fixing methods.
In addition, the support rib 315 may be disposed on the connecting plate section 312 of the grid plate 310, or may be disposed 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.
The support ribs 315 correspond one-to-one to the number of magnets 320. Taking two magnets 320 as an example, the two magnets 320 are respectively disposed on two lateral sides of the connecting plate 312, and accordingly, two lateral sides of the grating plate 310 are respectively provided with one supporting rib 315 to support the corresponding magnet 320.
In some embodiments, the plurality of vent holes 314a are distributed in multiple layers in the height direction. As shown, for example, in fig. 3 and 4, a plurality of vent holes 314a are distributed in an array across grid plate 310. The plurality of vent holes 314a may be distributed in multiple layers in the height direction, the plurality of vent holes 314a are uniformly distributed in each layer, and the plurality of vent holes 314a in each column are sequentially arranged in the height direction.
Of course, the plurality of vent holes 314a may be arranged in other manners. For example, they are arranged offset in the height direction. As long as the perforated plate section 314 of the grating plate 310 can be fully utilized and has a certain aesthetic property.
In some specific embodiments, the porosity of the plurality of vent holes 314a and the perforated plate section 314 is maintained between 60% and 70%. This ensures that both the ventilation efficiency meets the heat dissipation requirements of the nacelle and also the mechanical strength of the perforated plate section 314.
Referring to fig. 4 and 5, further, support ribs 315 are formed at the edges of the vent holes 314a at the uppermost layer and extend rearward. Since the highest-level ventilation holes 314a are adjacent to the connection plate sections 312 of the grid plates 310, providing the support ribs 315 on the edges of the highest-level ventilation holes 314a can satisfy the condition of supporting the magnets 320.
In addition, because the support ribs 315 are formed at the edges of the ventilation holes 314a at the highest layer and extend backwards, the manufacturing can be quickly realized by using a stamping die during the manufacturing, so that the complicated installation process is omitted, the number of parts is reduced, and the connection between the support ribs and the grid plate 310 is firmer.
Specifically, in the manufacturing process, the vent hole 314a to be provided with the support rib 315 is die-cut, and the area of the vent hole 314a is smaller than that of the remaining vent holes 314a. Then, the edges of the vent holes 314a are punched from front to back using a punching mold so that part of the edges are folded and protrude from the rear side surface of the grill plate 310, thereby not only forming the support ribs 315, but also making the areas of the vent holes 314a consistent with the areas of the remaining vent holes 314a after the secondary punching.
Referring to fig. 5, since the bottom front side of the box body 10 is provided with the skirting board 3, when the grating plate 310 is adsorbed on the box body 10 by the plurality of magnets 320, it can be butted with the skirting board 3 to be integrated, thereby improving the aesthetic property.
Referring to fig. 5, further, since in the above embodiment, the plurality of magnets 320 are supported only by the plurality of support ribs 315 without being limited above, when the grid plate 310 is attached to the box body 10, the lower edge of the skirting board 3 can also extend into the rear side of the grid plate 310 to abut against the upper surfaces of the plurality of magnets 320 from top to bottom, and further, the support ribs 315 together constrain the degree of freedom of the plurality of magnets 320 in the height direction, so that the magnets 320 are more stably disposed at the predetermined positions.
Referring to fig. 6 to 8, fig. 6 is a schematic view of a grill plate 310 in a ventilation grill assembly 30 according to another embodiment of the present invention, which shows a rear side of the grill plate 310 and a top flange 316, a side flange 318 and a support rib 315 thereon, fig. 7 is a cross-sectional view of the grill plate 310 in the ventilation grill assembly 30 according to another embodiment of the present invention, and fig. 8 is a schematic view of an assembly relationship between the ventilation grill assembly 30, a box 10, a door 20 and a skirting board 3 according to another embodiment of the present invention.
In other embodiments, a top flange 316 may be provided on the grid plate 310 to retain a plurality of magnets 320 above. Specifically, a top flange 316 is formed at the upper edge of the connecting plate section 312 and extends rearward to restrain the degree of freedom of the magnet 320 in the height direction in cooperation with the support rib 315.
When the magnet 320 is selected before assembly, the height of the magnet 320 should be ensured to be adapted to the height of the mounting gap between the top flange 316 and the support rib 315 as much as possible, so that the limit function of the top flange 316 can be effectively utilized, and the magnet 320 is in a stable state.
Referring to fig. 8, further, the width of top flange 316 in the front-back direction should be no greater than the width of magnet 320. In particular embodiments, the width of top flange 316 and the width of magnet 320 may also be consistent.
Since the magnet 320 needs to contact and adsorb the box body 10, once the width of the top flange 316 in the front-back direction is larger than the width of the magnet 320, the magnet 320 cannot directly contact and adsorb the box body 10, which greatly reduces the adsorption force of the magnet 320 on the box body 10, and even causes the grid plate 310 not to be stably mounted on the box body 10. Therefore, when the width of the top flange 316 is not greater than the width of the magnet 320, the top flange 316 does not interfere with the contact and adsorption of the magnet 320 and the case 10, thereby improving reliability.
Referring to fig. 6 to 8, further, the upper surface of the top flange 316 is provided with a first catching protrusion 316a, and when the grid plate 310 is attached to the box body 10, the first catching protrusion 316a abuts against the inner side of the skirting board 3 to restrain the degree of freedom of the grid plate 310 in the front-rear direction.
Before the ventilation grille assembly 30, the skirting board 3 may be fixedly connected to the refrigerator 1 or a cabinet for installing the refrigerator 1. In mounting the ventilation grill assembly 30, the magnet 320 is first mounted in advance on the back of the grill plate 310, and then pushed into a predetermined area on the skirting board 3 from the front to the rear, eventually causing the magnet 320 to be attracted to the front side surface of the case 10.
Because the top flange 316 is provided with the first engaging protrusion 316a, when the grid plate 310 is attached to the box 10, the first engaging protrusion 316a abuts against the inner side of the skirting board 3, so that the grid plate 310 cannot be separated from the skirting board 3 from the rear to the front, and the installation effect of the grid plate 310 is more stable.
Referring to fig. 6 to 8, further, one side and/or two side edges of the grid plate 310 are provided with side flanges 318 extending backward, and the outer sides of the side flanges 318 are provided with second engaging protrusions 318a, when the grid plate 310 is attached to the box 10, the second engaging protrusions 318a abut against the inner sides of the skirting boards 3, so as to restrict the degree of freedom of the grid plate 310 in the front-rear direction.
Similarly, when the ventilation grill assembly 30 is installed, when the grill plate 310 is attached to the cabinet 10, the grill plate 310 is pushed forward and backward into a predetermined area of the skirting board 3, and the second catching projections 318a abut against the inner surfaces of both lateral sides of the skirting board 3 to be engaged with the first catching projections 316a, thereby preventing the grill plate 310 from being separated forward and backward from the skirting board 3.
In addition, the first clamping protrusion 316a and the second clamping protrusion 318a can be formed by stamping and folding.
Referring to fig. 7, taking the first engaging protrusion 316a as an example, a cutting device may be used to cut a portion of the plate body on the top flange 316, but a portion of the plate body still connected to the top flange 316 is still needed (for example, a square area may be selected on the top flange 316, three sides of the square area are cut, and one side is remained), and then the portion of the plate body is pushed out of the upper surface of the top flange 316 from bottom to top by a tool, so as to form a first engaging protrusion 316a protruding out of the upper surface of the top flange 316 in a natural state.
Referring to fig. 7, in addition, the first catching protrusion 316a may be disposed in a position extending from the rear to the front and upward, so that when the grid plate 310 is pushed toward the box 10 from the front to the rear, the rear end of the first catching protrusion 316a reaches the skirting board 3 first, and the rear end is lower in height, which does not affect the pushing of the grid plate 310. In the process of continuing to push forward, the first latch-connection protrusion 316a gradually contacts with the skirting board 3, and after the skirting board 3 is pressed downward, the first latch-connection protrusion 316a retracts into the top flange 316, and generates an elastic restoring force. After the first clamping protrusion 316a completely passes through the skirting board 3, under the action of the elastic restoring force, the first clamping protrusion 316a is popped out of the surface of the top flanging 316 again, and the front end of the first clamping protrusion is abutted against the inner side of the skirting board 3, so that the magnet 320 is in contact with and adsorbed by the box body 10 right now, and the installation is completed.
The second catching projection 318a is formed in a similar manner to the first catching projection 316a except that the push-out direction after cutting is a lateral outer side, and will not be described herein.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made to the invention consistent with the principles of the invention, which may be directly determined or derived from the disclosure of the present invention, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
