The invention provides a grille component of an indoor unit of an air conditioner, which is arranged at an air inlet of the indoor unit of the air conditioner and is used for installing a filter screen so as to filter air entering the indoor unit. Referring to fig. 1, a grill assembly 100 of an indoor unit of an air conditioner according to the present invention includes a top frame 10, a bottom frame 20, and a screen bracket 30.

Referring to fig. 2, the filter screen bracket 30 has two first sidewalls 31 disposed oppositely, each of the two first sidewalls 31 has a first slot 311 with an opening facing the top frame 10 and a second slot 312 with an opening facing the bottom frame 20, and the two first slots 311 and the second slots 312 are disposed in a staggered manner along the length direction of the first sidewall 31 where they are located, so that the heights of the two first sidewalls 31 can be reduced, and the height of the entire filter screen bracket 30 can be reduced.

Referring to fig. 3, the top frame 10 is provided with a first inserting plate 11 corresponding to the first slot 311.

Referring to fig. 4, the chassis 20 is provided with a second board 21 corresponding to the second slot 312.

Referring to fig. 5 and 6, when the grill assembly 100 is assembled, the first insert plate 11 of the top chassis 10 is inserted into the first insert slot 311 of the first sidewall 31 of the screen support 30, and the second insert plate 21 of the bottom chassis 20 is inserted into the second insert slot 312 of the first sidewall 31 of the screen support 30. The top frame 10 and the bottom frame 20 are not interfered with each other when being inserted into the screen support 30, so that the assembly of the grill assembly 100 is facilitated.

In the invention, the first slot 311 with an opening facing the top frame 10 and the second slot 312 with an opening facing the bottom frame 20 are arranged on the two oppositely arranged first side walls 31 of the filter screen bracket 30, and the first slot 311 and the second slot 312 are arranged in a staggered way along the length direction of the first side wall 31 where the first slot 311 and the second slot 312 are arranged. In this manner, the height of the screen support 30 is advantageously reduced, which in turn facilitates a reduction in the thickness of the overall grill assembly 100, thereby achieving a reduction in the size of the grill assembly 100.

In order to make the assembly of the grill assembly 100 more secure, a plurality of first slots 311 and a plurality of second slots 312 are formed on each of the first side walls 31; correspondingly, a plurality of first insertion plates 11 are correspondingly arranged on the top frame 10, and a plurality of second insertion plates 21 are correspondingly arranged on the bottom frame 20. The top frame 10 is correspondingly inserted into the first slots 311 of the filter screen bracket 30 through the first inserting plates 11, and the bottom frame 20 is correspondingly inserted into the second slots 312 of the filter screen bracket 30 through the second inserting plates 21, so that the connection between the filter screen bracket 30 and the top frame 10 and the bottom frame 20 is firmer.

Further, referring to fig. 2, the plurality of first slots 311 and the plurality of second slots 312 are alternately arranged along the length direction of the first sidewall 31 where the plurality of first slots are located. It should be noted that, the alternating arrangement described herein may be such that a first slot 311, a second slot 312, and a first slot 311 … … are arranged; two first slots 311, two second slots 312, and two first slots 311 … … may also be arranged in this way; of course, the first slot 311 and the second slot 312 may be alternatively arranged in other arrangement manners, and are not limited in this respect.

To facilitate the insertion of the first board 11 into the first slot 311 and the insertion of the second board 21 into the second slot 312, referring to fig. 3 and 4, the first board 11 is gradually tapered from the end connected with the top frame 10 to the free end thereof, and the second board 21 is gradually tapered from the end connected with the bottom frame 20 to the free end thereof. So set up, make the width of the free end of first picture peg 11 be less than the notch width of first slot 311, the width of the free end of second picture peg 21 is less than the notch width of second slot 312, and then made things convenient for first picture peg 11 and second picture peg 21 to insert in corresponding first slot 311 and second slot 312, thereby made things convenient for the equipment of grid subassembly 100.

Referring to fig. 3, the top frame 10 has two second sidewalls 12 disposed oppositely, and the two second sidewalls 12 are both provided with a plurality of first notches 121 having openings facing the first sidewalls 31, and the first board 11 is formed between two adjacent first notches 121. When the top frame 10 is assembled with the strainer holder 30, the first inserting plate 11 is inserted into the first inserting groove 311, and the bottom wall of the first notch 121 abuts against the first sidewall 31, thereby facilitating to reduce the volume of the grille assembly 100.

Referring to fig. 4, the bottom chassis 20 has two third sidewalls 22 disposed oppositely, and each of the two third sidewalls 22 has a plurality of second notches 221 with openings facing the first sidewall 31, and the second insert plate 21 is formed between two adjacent second notches 221. When the bottom frame 20 is assembled with the filter screen bracket 30, the second insert plate 21 is inserted into the second insert slot 312, and the bottom wall of the second notch 221 abuts against the first sidewall 31, thereby facilitating to reduce the volume of the grille assembly 100.

In order to make the assembly of the grill assembly 100 more secure, i.e., to make the screen frame 30 more securely connected to the top frame 10 and the bottom frame 20, referring to fig. 2, a first fastening platform 313 is disposed on a wall of the first slot 311, and a second fastening platform 314 is disposed on a wall of the second slot 312; correspondingly, referring to fig. 3 and 4, the first board 11 is provided with a first fastening hole 111, and the second board 21 is provided with a second fastening hole 211. Referring to fig. 5 and 7, when the first board 11 is inserted into the first slot 311, the first fastening hole 111 of the first board 11 is fastened to the first fastening platform 313; when the second board 21 is inserted into the second slot 312, the second fastening hole 211 of the second board 21 is fastened to the second fastening platform 314. The first retaining step 313 is effective to limit the disengagement of the first board 11 from the first slot 311, and the second retaining step 314 is effective to limit the disengagement of the second board 21 from the second slot 312. In this manner, the screen support 30 is more securely coupled to the top frame 10 and the bottom frame 20.
