Embodiment 1

[0049] see figure 1 , figure 2 and Figure 5 , a range hood is a top-suction range hood, including a smoke collection hood 1, a box 2 arranged above the smoke collection hood 1, a fan 3 arranged in the box 2, and a smoke collection assembly. For the convenience of description, in this specification, "front", "rear", "left", "right", "up", and "down" refer to the direction of the range hood relative to the user when in use.

[0050] The smoke collection hood 1 includes a top plate 11 extending transversely, a side plate 12 located at the periphery of the top plate 11 and extending downward in the longitudinal direction, so that an upwardly recessed smoke collection chamber 13 is formed in the smoke collection hood 1, and an entrance is opened on the top plate 11. The tuyere 14 makes the smoke collecting chamber 13 communicate with the inside of the box body 2 . In this embodiment, there are four side panels 12, which are surrounded by a substantially rectangular shape.

Embodiment 2

[0064] see Figure 16 and Figure 17 , In this embodiment, the difference from the first embodiment above is that the oil scraper assembly includes a first oil scraper block 441', a second oil scraper block 442', a third oil scraper block 443' and a fourth oil scraper block 444 'replaces four scrapers. The oil scraping assembly also includes a first screw rod 445', a second screw rod 446, a third motor 447 and a fourth motor 448. The first threaded mandrel 445' and the second threaded mandrel 446 are located near the side plates 12 on the left and right sides of the fume collecting hood 1, respectively.

[0065] Wherein, the first threaded rod 445' extends in the front-to-rear direction and is located above the first smoke collecting plate 41, the first oil scraper block 441' and the second oil scraper block 442' are screwed with the first threaded rod 445' respectively, In addition, the helical directions of the threads of the first screw rod 445' and the first oil scraper...

Embodiment 3

[0073] see Figure 24 , in this embodiment, the difference from the first embodiment above is that the scraper assembly also includes a first movable scraper 441", a second movable scraper 442", a third movable scraper 443" and a fourth movable scraper 444".

[0074] The first movable oil scraper 441 ″ and the second movable oil scraper 442 ″ extend in the left and right directions respectively, and one of them is close to the side plate 12 on the front side of the smoke collection hood 1 , and the other is close to the side plate 12 on the rear side of the smoke collection hood 1 . Similarly, the third movable oil scraper 443 ″ and the fourth movable oil scraper 444 ″ also extend in the left and right directions respectively, and one of them is close to the side plate 12 on the front side of the fume collection hood 1 , and the other is close to the rear side of the fume collection hood 1 side panels 12.

[0075] The oil scraping assembly also includes a first threaded rod...

Abstract

The invention discloses a range hood, which includes a smoke collecting hood and a smoke collecting assembly. The smoke collecting hood is provided with an air inlet. The smoke collecting assembly includes a smoke collecting plate located below the air inlet. The smoke collecting plate The smoke collection hood is movably arranged on the smoke collecting hood, so that the smoke collecting plate can be in a closed position to close the air inlet and an open position to open at least part of the air inlet. It is characterized in that: the smoke collecting assembly also includes a smoke collecting plate capable of closing the air inlet. An oil scraping assembly is used to scrape off oil stains on the surface of the smoke collecting plate during the movement of the smoke collecting plate. An oil cup assembly for receiving oil stains is provided at the outer end of the smoke collecting plate. By arranging an oil scraper assembly on the smoke collecting hood that can scrape off the oil stain accumulated on the surface of each smoke collecting plate, it is possible to expand the smoke collection range and improve the effect of oil smoke absorption, while avoiding the accumulation of oil stains on the surface of the smoke collecting plate due to long-term use. It affects the normal function, thereby reducing the cleaning frequency and extending the service life.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oily fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the essential equipment in modern home kitchens. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used due to their neatness, lightness, and small footprint. [0003] The top-suction range hood usually includes a fume collection hood, a fan casing positioned on the fume collection hood, and a volute, an impeller and a motor for driving the impeller are installed in the fan casing. Oily fume generated during the cooking process is collected in the fume collecting hood, passes through an air inlet connected with the fume collecting hood, and then is discharged outside through an air duct. [0004] Common stoves a...
