Referring to fig. 1 to 3, the range hood with a small blind area of oil smoke absorption includes: a main unit 100 provided with a negative pressure chamber 110 and a main oil smoke hole 120 communicated with the negative pressure chamber 110; the oil collecting cover 200 is arranged on the host 100, the oil collecting cover 200 is provided with an auxiliary oil smoke suction hole 210, and the auxiliary oil smoke suction hole 210 is communicated with the negative pressure cavity 110.

In the range hood, the oil smoke is mainly sucked away through the main oil smoke suction hole 120 on the main machine 100, and the auxiliary oil smoke suction hole 210 is further arranged on the oil collection cover 200, so that the oil smoke can be sucked nearby the oil collection cover 200, the oil smoke suction blind area of the range hood is reduced, the escape of the smoke is reduced, and the surface oil stain formed by the oil smoke fumigation at the oil collection cover 200 can also be reduced.

Referring to fig. 3, in the present embodiment, the oil collecting cover 200 has an oil collecting groove 220, the secondary soot hole 210 is opened at the bottom of the oil collecting groove 220, and the hole wall of the secondary soot hole 210 extends toward the inside of the oil collecting groove 220 and forms a first oil slinger 230. Through the arrangement of the first oil slinger 230, the oil collected in the oil collecting tank 220 can be prevented from leaking through the auxiliary oil smoke suction hole 210.

Referring to fig. 4, in the present embodiment, the main body 100 is combined by a main housing 101 and a panel assembly 102. In this embodiment, the oil collecting cover 200 is disposed at the bottom of the host 100 and is detachably disposed, which may be implemented by a plug structure, a threaded connection, or the like.

Referring to fig. 5 to 6, in the present embodiment, an oil receiving plate 130 for receiving oil stains is disposed at a lower side of the negative pressure chamber 110, an oil collecting cover 200 is disposed at a lower side of the oil receiving plate 130, an oil discharge hole 140 for allowing the oil stains to enter the oil collecting cover 200 is disposed on the oil receiving plate 130, and a communication hole 150 for allowing the sub-oil smoke suction hole 210 and the negative pressure chamber 110 to communicate with each other is further disposed on the oil receiving plate 130. On the main unit 100, oil stains are collected mainly by the oil collecting plate 130, and the oil stains flow into the oil collecting groove 220 of the oil collecting cover 200 through the oil discharge hole 140 to be collected. And the sub-soot absorption hole 210 can be communicated to the negative pressure chamber 110 by providing the communication hole 150 on the oil receiving plate 130. In this embodiment, the oil drain hole 140 can also serve to communicate the sub-range suction hole 210 with the negative pressure chamber 110.

In this embodiment, the communication hole 150 is disposed opposite to the auxiliary smoke exhaust hole 210, so that the smoke can directly enter the negative pressure chamber 110 through the communication hole 150 after being inhaled from the auxiliary smoke exhaust hole 210, the smoke path is short, and the smoking effect is good. Referring to fig. 3, the path of the oil smoke sucked into the negative pressure chamber 110 is shown by a hollow arrow in the figure; the solid arrows in fig. 3 show the path of the liquid oil.

In the present embodiment, an oil blocking portion 160 is provided above the communication hole 150. Since oil stains may frequently fall on the oil receiving plate 130 in the negative pressure chamber 110 of the main unit 100, the oil blocking portion 160 is disposed above the communication hole 150, so that the probability that the oil stains in the negative pressure chamber 110 fall to the sub-smoke suction hole 210 through the communication hole 150 can be reduced.

In this embodiment, the oil blocking portion 160 is a conical cover, and the relatively small end of the conical cover is disposed upward, so as to reduce the accumulation of oil on the oil blocking portion 160.

In the present embodiment, the oil receiving plate 130 is provided with a boss portion 131, and the communication hole 150 is provided in the boss portion 131. The boss portion 131 is higher than the other portion of the oil receiving plate 130, so that oil contamination is prevented from accumulating around the communication hole 150, and the probability that the oil contamination falls down to the sub-range hood hole 210 through the communication hole 150 is reduced. In the present embodiment, the orifice wall of the communication hole 150 extends upward to form the second slinger 170. By providing the second oil slinger 170, the oil contamination is caught by the second oil slinger 170, thereby reducing the probability that the oil contamination falls to the sub-range-smoking hole 210 through the communication hole 150. In some embodiments, in order to prevent oil from accidentally dropping from the secondary fume hole 210 to the cooking bench, some oil blocking structures, such as oil blocking plates, may be disposed at the lower side of the secondary fume hole 210.

In the present embodiment, the oil collection cover 200 is configured in an elongated shape, and the plurality of sub-smoke exhaust holes 210 are provided and arranged along the length direction of the oil collection cover 200. In the present embodiment, the communication hole 150 is provided in plurality and is disposed opposite to the sub-range-smoking holes 210 one by one. In the present embodiment, the secondary soot holes 210 are circular holes, but it is conceivable that the secondary soot holes 210 may be long holes in other embodiments, and the number of the secondary soot holes 210 may be configured according to the actual situation.

The range hood shown in the drawings is a side-draft range hood, but the structure of the embodiment is not limited to be applied to the side-draft range hood, and can be applied to other types of range hoods, such as a top-draft range hood (T-type), a "7" range hood (range hood combining top-draft and side-draft), and the like, and the structure of the embodiment can also be adopted so as to reduce the blind area of oil smoke absorption of the range hood and enhance the effect of oil smoke absorption.

All possible combinations of the technical features in the above embodiments may not be described for the sake of brevity, but should be considered as being within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
