Example one

As shown in fig. 1 and fig. 2, this embodiment provides a kitchen appliance, which may be a range hood 100, an integrated kitchen range, etc., in this embodiment, the range hood 100 is taken as an example for description, the range hood 100 includes a host 70, a smoke collection chamber main body 10, and a flap assembly, the host 70 includes a housing 71 and a fan 72, the fan 72 is disposed in the housing 71, when the fan 72 works, the fan 72 forms a negative pressure in the housing 71, the smoke collection chamber main body 10 includes a smoke collection chamber 11, the smoke collection chamber 11 has an air inlet 111 and an air outlet 112, the smoke collection chamber 11 is communicated with an inner cavity of the housing 71 through the air outlet 112, the flap assembly is disposed at the air inlet 111, and the flap assembly can open or block the air inlet 111.

As shown in fig. 1 and 2, when the range hood 100 works, the flap assembly opens the air inlet 111, the fan 72 works to generate negative pressure, and the negative pressure enables the oil smoke outside the range hood 100 to sequentially pass through the air inlet 111, the smoke collection chamber 11, the air outlet 112, the shell 71 and the fan 72 and then be discharged out of the shell 71, so that the oil smoke is absorbed and discharged by the range hood 100.

As shown in fig. 2, the front side of host 70 is located the rear of the front side of collection smoke chamber main part 10 and arranges with the front side interval of collection smoke chamber main part 10, and when cabinet door 200 is installed to lampblack absorber 100, host 70 is located the rear side of cabinet door 200, and cabinet door 200 can realize the better effect of sheltering from to host 70. In addition, as shown in fig. 2, the front side of the cabinet door 200 is coplanar with the front side of the smoke collecting chamber body 10, so that the range hood 100 mounted on the cabinet door 200 is more beautiful as a whole.

As shown in fig. 1, the flap assembly includes a first flap 20 and a second flap 30, and the first flap 20 and the second flap 30 realize switching between different states of turning off and turning on the range hood 100 by adjusting respective postures of the first flap 20 and the second flap 30.

Particularly, as shown in fig. 1, when lampblack absorber 100 is in the shutdown state, the turning plate assembly plugs air inlet 111 completely, oil drops in smoke collection cavity 11 can be prevented from dropping on the cooking bench by the turning plate assembly, the turning plate assembly can also shield parts in smoke collection cavity 11, and the lampblack absorber 100 is more attractive in the shutdown state. As shown in fig. 1, when the air inlet 111 is closed jointly by the first turning plate 20 and the second turning plate 30, the first turning plate 20 is located above and at the front side of the second turning plate 30, the first turning plate 20 and the second turning plate 30 are arranged at an obtuse angle, which is equivalent to the fact that the protruding structure formed by the first turning plate 20 and the second turning plate 30 extends into the smoke collection chamber 11, thereby releasing the space below a part of the range hood 100, facilitating the cleaning of the user on the cooking bench when the range hood 100 is in a closed state, and avoiding the risk of the user touching the cooking bench when cleaning the cooking bench.

In addition, as shown in fig. 2, the range hood 100 is in a first working state: when the user explodes the stir-fry or the great culinary art process of oil smoke volume, first board 20 and the second of turning over turns over the board 30 and opens simultaneously, first board 20 that turns over overturns forward, the second turns over board 30 and to the inside upset of collection cigarette chamber 11, air inlet 111 opens completely, first board 20 that turns over stops after arriving and holding up the cigarette state, by first board 20 that turns over, the closed cigarette area of holding up around collection that collection cigarette chamber 11 lower surface and wall formed is linked together with collection cigarette chamber 11, it is used for assisting to hold up the cigarette area. The first board 20 that turns over opens and makes the space that holds together the cigarette region bigger, and the first board 20 that turns over has shortened to a great extent after opening and has held together the distance of cigarette region and fuming region, therefore can absorb more oil smoke before the oil smoke drifts away and escapes, prevents that the cigarette effect is stronger.

In addition, as shown in fig. 3, the range hood 100 is in a second working state: first board 20 that turns over is closed, and the second turns over board 30 and opens, and air inlet 111 is only partly opened, and the open part of air inlet 111 satisfies the recovery to a small amount of oil smoke or vapor, can match the user and use cooking utensils to burn water and scald water etc. and only have the operating condition that vapor or the culinary art process of a small amount of oil smoke correspond. At this time, the range hood 100 is in a low gear, noise of the range hood 100 is small, and due to the fact that the area of the air inlet 111 is reduced at this time, the oil smoke flow rate of the air inlet 111 is faster, and efficiency of the range hood 100 is higher.

As shown in fig. 1-3, range hood 100 further includes a smoke blocking assembly 60, smoke blocking assembly 60 is disposed in smoke collection chamber 11 and located between air inlet 111 and air outlet 112, smoke blocking assembly 60 can diffuse the negative pressure concentrated in the area of air outlet 112 to the periphery of smoke collection chamber 11, smoke leakage prevention performance of range hood 100 is enhanced, smoke blocking assembly 60 can realize preliminary oil smoke separation to improve the oil smoke absorption effect of range hood 100, but oil drops on smoke blocking assembly 60 can fall on the flap assembly, resulting in uncleanness of the flap assembly, and influence the experience of user using range hood 100.

As shown in fig. 4, the smoke blocking assembly 60 is formed to form a first negative pressure cavity 634, the first negative pressure cavity 634 is recessed toward the air outlet 112 (not shown) from the side of the smoke blocking plate 61 away from the air outlet, a first flow guide opening 635 communicated with the air outlet 112 (not shown) is formed on the side wall of the first negative pressure cavity 634, due to the arrangement of the first negative pressure cavity 634 and the small sectional area of the first flow guide opening 635, the flow rate of the oil smoke flowing through the first negative pressure cavity 634 and the first flow guide opening 635 is fast, the pressure difference between the inside and the outside of the first flow guide opening 635 is larger, the oil smoke around the smoke collecting cavity 11 flows to the area of the first flow guide opening 635, and the range hood 100 has stronger smoke leakage prevention capability.

Specifically, as shown in fig. 4, the smoke baffle assembly 60 includes two smoke baffles 61 and a first connecting plate 63, the smoke baffles 61 are opposite to the air outlet 112, the two smoke baffles 61 are arranged at intervals along the width direction of the smoke collection cavity body 10, the first connecting plate 63 is arranged on one side of the smoke baffles 61 facing the air outlet 112 (not shown in the figure), the first connecting plate 63 includes a first connecting side plate 631, a first connecting bottom plate 632 and a second connecting side plate 633 which are connected in sequence, the first connecting side plate 631 and the second connecting side plate 633 are respectively connected with the corresponding smoke baffles 61, the first connecting side plate 631, the first connecting bottom plate 632 and the second connecting side plate 633 together form a first negative pressure cavity 634, and the first connecting side plate 631 and the second connecting side plate 633 are respectively provided with a first drainage port 635.
