Description

Technical Field

[0001] The utility model relates to a filter screen for range hoods, and belongs to the technical field of filter screens for range hoods. Background Art

[0002] A range hood, also known as a smoke extractor, is a kitchen appliance that purifies the kitchen environment. Installed above the kitchen stove, it quickly extracts waste from stove combustion and harmful cooking fumes, exhausting them outdoors. It also condenses and collects the fumes, reducing pollution, purifying the air, and providing safety features like anti-toxicity and explosion protection.

[0003] A single filter is usually installed in an inclined state at the entrance of the range hood. When high-temperature oil smoke or water vapor encounters the low-temperature filter, water droplets or oil stains will appear on the surface of the filter. When there are too many water droplets or oil stains, they will slide down the filter and eventually drip onto the stove or pot. This is not only unhygienic, but also more troublesome to clean the stove later. Utility Model Content

The bottom ends of the two first mounting frames 9 and the bottom ends of the second mounting frame 12 are movably inserted into the three slots 5 respectively, and both sides of the upper end of the base 2 are fixedly connected with plug-in blocks 7 adapted to the grooves 17. One side of the two plug-in blocks 7 is provided with a positioning groove 16. Two positioning mechanisms 4 are provided on the outside of the outer frame 1, and the two positioning mechanisms 4 correspond to the two plug-in blocks 7 respectively. Water droplets or oil stains are collected through the water collection trough 6, which is convenient for centralized cleaning later. At the same time, it can also prevent oil stains or water droplets from dripping onto the stove to ensure hygiene.

[0021] The two positioning mechanisms 4 each include a pull block 41, a spring 42, a positioning rod 43 and a first arc surface 44. One end of the positioning rod 43 passes through the outer frame 1 and is movably inserted into the positioning groove 16. The positioning rod 43 is movably sleeved with the outer frame 1. The bottom of one end of the positioning rod 43 located inside the positioning groove 16 is provided with a first arc surface 44. The other end of the positioning rod 43 is fixedly connected to the pull block 41. A spring 42 is fixedly connected between the pull block 41 and the outer wall of the outer frame 1. The spring 42 is sleeved on the periphery of the positioning rod 43. When the pull block 41 is pulled, the pull block 41 drives the positioning rod 43 to move. When the positioning rod 43 is separated from the positioning groove 16, the base 2 can be separated from the outer frame 1, and then the first mounting frame 9 and the second mounting frame 12 can be disassembled at the same time, and the first gear rod 10 and the second gear rod 13 can be cleaned more conveniently. On one side of the upper end of the two insert blocks 7 Each of them is provided with a second curved surface 15, and the two second curved surfaces 15 correspond to the two first curved surfaces 44 respectively. When splicing the base 2 and the outer frame 1, the plug 7 is inserted into the groove 17, and contacts the first curved surface 44 through the second curved surface 15, so that the plug 7 pushes the positioning rod 43 to move horizontally, and finally the positioning rod 43 is inserted into the positioning groove 16 through the restoring force of the spring 42, thereby completing the splicing of the base 2 and the outer frame 1; a number of water collecting grooves 6 are provided on one side of the three slots 5, and water droplets or oil stains are collected through the water collecting grooves 6, which is convenient for centralized cleaning later; a number of first gear rods 10 and a number of second gear rods 13 are provided with guide grooves 3 at the front end, and a number of guide grooves 3 correspond to a number of water collecting grooves 6 respectively. The guide grooves 3 facilitate the diversion of water droplets or water stains, so that they flow into the water collecting grooves 6.

[0022] Specifically, when the present invention is used, the outer frame 1 is installed at an angle at the organic inlet. When the flue gas enters the range hood, the flue gas will fully contact the first gear rod 10 and the second gear rod 13, thereby condensing the oil stains or water vapor in the flue gas. The water droplets or oil stains will eventually flow into several water collection tanks 6 along the guide groove 3. The water droplets or oil stains are collected centrally by the water collection tank 6, which is convenient for centralized cleaning later. At the same time, it can also prevent oil stains or water droplets from dripping onto the stove to ensure hygiene. Later, the pull block 41 is pulled, and the pull block 41 drives the positioning rod 43 to move. When the positioning rod 43 is separated from the positioning groove 16, the base 2 can be separated from the outer frame 1, and then the first mounting frame 9 and the second mounting frame 12 can be disassembled at the same time, and the first gear rod 10 and the second gear rod 13 can be cleaned, which is more convenient.

[0023] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
