A water collection tank 13 formed at the bottom of the casing 11, an atomization chamber 14 arranged in the casing 11, a water spray pipe 15 arranged in the atomization chamber 14, and a spray pipe 15 arranged in the collection In the water tank 13 and connected to the water pump 16 of the water spray pipe 15.

When in use, the existing water waterfall type range hood 1 is arranged indoors, and the indoor oil fume is sucked by the air exhaust device 12, and the water at the bottom of the sump 13 is extracted by the water pump 16, and the water is drawn out by the water spray pipe 15. Cooperate with the atomization chamber 14 to form a water waterfall to wash the oily particles in the oil fume into the sump 13, thereby preventing the oily particles from being directly discharged outside.

However, the existing water waterfall type cooker hood 1 uses the water waterfall to wash away the lampblack, so some greasy dirt particles will still be discharged outside through the gap of the water waterfall. And the existing water waterfall type range hood 1 is arranged indoors, and the ventilation device 12 is directly arranged on the housing, so larger noises can be produced during operation, which affects the living quality.

Therefore, in order to improve the shortcoming of the existing water waterfall type range hood, some people in the industry proposed the patent case of "Water-washed range hood filter" as the No. M367311 announcement in Taiwan, China. Referring to Fig. 2, the existing water-washing oil fume filter 2 comprises a filter bucket 21, a filter screen 22 arranged in the filter screen 21, an aerosol device 23 arranged below the filter screen 22, and a filter screen connected to the filter screen 22. Circulator 24 for barrel 21 . The filter barrel 21 includes a barrel body 211, a discharge hole 212 formed on the barrel body 211 and above the filter screen 22, and a discharge hole 212 formed on the side wall of the barrel body 211 and positioned below the aerosol device 23. Oil fume enters the hole 213 .

When in use, a range hood 3 installed in the room will send the oil fume into the filter barrel 21 from the oil fume inlet hole 213, and the oil particles are washed by the aerosol generated by the aerosol device 23 and collected in the filter. barrel 21 bottom. Part of the oily particles going upward through the aerosol will be adsorbed on the filter screen 22 , thereby reducing the air pollution caused by the oily particles being discharged out of the filter barrel 21 through the discharge hole 212 . However, part of the greasy dirt particles can still be discharged out of the filter barrel 21 through the discharge hole 212 along with the airflow passing through the slit of the filter screen 22 . In addition, the greasy dirt particles will soon fill up the filter holes of the filter screen 22, causing the filter screen 22 to be clogged and the air flow cannot be discharged. The filter screen 22 must be replaced frequently to maintain normal operation. And this range hood 3 is arranged indoors, so still can't improve the problem of generating noise during operation.

Therefore, although the existing water washing oil fume filter 2 has slightly improved the problem of poor filtering effect of the existing water waterfall type oil fume exhaust machine 1, some oily particles will still be discharged through the gaps of the filter screen 22, and the filter screen 22 Very easily clogged by oily particles and must be replaced frequently to maintain proper operation. In addition, the range hood 3 installed indoors still produces noise during operation, which adversely affects the quality of life at home, so it is necessary to improve the above shortcomings.
