For the purposes of making the objects, aspects and advantages of the present application more apparent, the present application will be further described with reference to the drawings and preferred embodiments.

A range hood embodiment as presented herein includes a blower, a housing 1, a fume collection hood 2, a decorative hood 14, and an oil cup 3, as shown in fig. 1-8. The fan is arranged in the casing 1, in particular in a cavity of the casing 1. The shell 1, the fume collecting hood 2 and the oil cup 3 are sequentially arranged from top to bottom. The decorative cover 14 is U-shaped and is shielded from the casing 1, as shown in fig. 2. The smoke exhaust ventilator is a top suction type smoke exhaust ventilator.

The fume collecting hood 2 comprises a fume collecting cavity 4, an inner cavity, a touch panel 15 and a top cover plate. The fume collecting hood 2 is in a cuboid shape as a whole. The inner cavity is spliced on the smoke collecting cavity 4 from top to bottom, and an air flow channel is spliced between the inner cavity and the smoke collecting cavity 4. The top cover plate is put on the top edge of the smoke collecting cavity 4, and the top cover plate shields the inner cavity from top to bottom. The top of the cavity is provided with two engagement edges 13 arranged in opposite directions, as shown in fig. 2, the two engagement edges 13 protrude out of the top cover plate. Two engagement edges 13 for engaging the bottom edge of the casing 1. Specifically, the two engagement edges 13 are fixed to the bottom edge of the casing 1 by screws. When the two connecting edges 13 are connected with the shell 1, an air flow channel formed by splicing the inner cavity and the smoke collecting cavity 4 is communicated with the cavity of the shell 1.

The wall of the smoke collecting cavity 4 is cut to form a plurality of air inlet holes 12. A plurality of air inlet holes 12 are arranged to allow the flow of the cooking fume collected by the fume collecting chamber 4 to pass through and enter the range hood. A plurality of air inlet holes 12, together forming a sieve zone 6, are arranged to be adapted to filter out grease from a flowing stream of cooking fumes. The air inlets 12 are the only air inlets of the smoke collecting cavity 4. Specifically, a plurality of air inlet holes 12 are formed on the wall body of the smoke collecting cavity 4 through a stamping process.

The smoke collecting chamber 4 is shown in fig. 5 to 8. The smoke collecting cavity 4 is formed by integrally forming a metal plate. The rim of the smoke collecting chamber 4 protrudes upwards to form a U-shaped side wall as shown in figure 5. And figure 6 shows a view from above the U-shaped side wall looking down at the smoke collecting chamber 4. Therefore, the filter screen area 6 is integrally formed on the wall body of the smoke collecting cavity 4, so that gaps are reduced, cleaning is facilitated, and the risk of scratching hands of the filter screen area 6 can be reduced.

The U-shaped opening of the U-shaped side wall faces the rear edge 7 of the smoke collecting chamber 4 as shown in fig. 5. The U-shaped side wall comprises a left wall 8, a front wall 9 and a right wall 10 which are connected in sequence. The touch panel 15 is fixed against the front wall 9 as shown in fig. 3.

The screen area 6 is arranged obliquely downwards from front to back. The air inlet holes 12 are elongated holes extending towards the rear edge 7 of the smoke collecting cavity 4, as shown in fig. 1, 3, 5 and 6. A plurality of air intake holes 12 are arranged in an array. Specifically, the plurality of air intake holes 12 are disposed in parallel with each other. There are 17 total air intake holes 12. The edges of the air inlets 12 are raised upwards to form a circle of oil guiding flanging.

The rear edge 7 of the smoke collecting cavity 4 is provided with oil leakage holes 11. The oil cup 3 is hung on the rear edge 7 of the smoke collecting cavity 4, and the opening faces the oil leakage hole 11, as shown in fig. 1 and 4. The oil cup 3 is an elongated groove. The grease filtered by the screen area 6 flows to the oil leakage hole 11 under the action of gravity, and then flows through the oil leakage hole 11 and flows into the oil cup 3.

The smoke collecting cavity 4 is provided with a non-porous smoke guiding wall 5. The filter screen area 6 is square. The left, front and right edges of the screen zone 6 are all joined to the non-porous smoke guide wall 5 as shown in figures 1, 3, 5 and 6. The rear edge of the filter screen area 6 is connected with the rear edge 7 of the smoke collecting cavity 4. A non-porous smoke-guiding wall 5 partially surrounding the screen area 6. The non-porous smoke guiding wall 5 converges obliquely upwards towards said screen zone 6.

The fume collecting cavity 4 faces the fume source below the fume extractor from top to bottom. Specifically, the fume collecting cavity 4 faces the kitchen range below the range hood from top to bottom.

When a user cooks on the cooking bench, the smoke exhaust ventilator is started, the fan is operated to form negative pressure, and oil smoke air flow is generated, flows to the filter screen area 6 under the guidance of the non-hole smoke guide wall 5, then flows through the filter screen area 6 (specifically, the oil smoke air flow passes through the air inlet hole 12), flows into an air flow channel formed by splicing the inner cavity and the smoke collecting cavity 4, then flows into the cavity of the machine shell 1, flows through the fan, and then is discharged into the public flue.
