Description

Refrigerator and ventilation grille assembly thereof Technical Field The invention relates to the field of refrigerators, in particular to a refrigerator and a ventilation grid assembly thereof. Background In order to achieve a better integrated effect with a cabinet, the existing free embedded refrigerator is provided with a skirting part at the bottom, however, the skirting part may affect heat dissipation of the refrigerator. In order to increase the ventilation effect between the embedded refrigerator and the external environment in the prior art, a ventilation grid is arranged at the bottom of the refrigerator, and the ventilation grid is connected with the refrigerator (or a cabinet around the refrigerator) through fastening, a welding machine and the like, so that the refrigerator is inconvenient to install and detach by a user. Disclosure of Invention It is an object of the present invention to overcome at least one of the disadvantages of the prior art and to provide a refrigerator and a ventilation grille assembly thereof. A further object of the present invention is to facilitate the mounting of a ventilation grille assembly to a cabinet of a refrigerator. It is a further object of the present invention to facilitate the formation of support bars for supporting magnets in the grid plate. In particular, the invention provides a ventilation grille assembly for a refrigerator, which is arranged below the front side of a refrigerator body of the refrigerator, and comprises a grille plate, a plurality of ventilation holes and a plurality of magnets, wherein the grille plate is provided with the ventilation holes, the magnets are arranged at the rear side of the grille plate, so that the grille plate is fixed below the front side of the refrigerator body, and at least part of the ventilation holes face to the bottom space between the bottom plate of the refrigerator body and the ground, and the bottom space is communicated with the external environment through the ventilation holes. Optionally, the grid plate further includes a plurality of supporting ribs, each of the plurality of supporting ribs is disposed at a rear side of the grid plate, and the number of the supporting ribs corresponds to the number of the magnets one by one so as to support the magnets. Optionally, a plurality of vent holes are distributed in a plurality of layers in a height direction, and a support rib is formed at an edge of the vent hole at the highest layer and extends rearward. Optionally, a plurality of vent holes are distributed in an array on the grid plate. Optionally, a top flange extending backward is formed at the upper edge of the grid plate, and the top flange and the support ribs jointly restrict the degree of freedom of the magnet in the height direction. Alternatively, the width of the top flange is set to be not larger than the width of the magnet in the front-rear direction.
