The range hood as an indispensable household appliance in a kitchen takes an increasingly important position in people's daily life. When the range hood works, oil smoke is sucked from the air inlet and is exhausted outdoors through the flue. The existing household range hood on the market is generally divided into a top suction type and a side suction type: the air inlet of the top-suction range hood is positioned at the top end of the cooking bench, so that the range hood is attractive in style, but inconvenient to install due to overhigh installation height during installation, and is easy to touch during cooking, so that inconvenience is brought to users, the air inlet is far away from oil smoke, and the smoking effect is poor; the air inlet of the side-draft range hood is close to the cooking bench, the smoking effect is good, but the style is not attractive, and the occupied kitchen space is large.

On the other hand, most of the fan systems of the existing conventional range hoods are multi-wing centrifugal fans, air is fed into a single hole, and an air inlet channel cannot be adjusted according to the use condition of a cooking bench; the static pressure of the multi-wing centrifugal fan is low, the negative pressure area is small, the negative pressure centralized guide is lacked, and the oil smoke suction and exhaust effect is not ideal; the existing double-air-inlet range hood needs to be provided with two driving mechanisms, so that the cost and the complexity of the range hood are greatly improved, the range hood is overlarge in size and not attractive, and noise pollution is increased.

Based on the above, the utility model provides a range hood, which is used for relieving the problem that the top-suction range hood in some technologies has beautiful style, but is easy to touch the head, and the air inlet is far away from the oil smoke, so that the smoking effect is poor; the side-draft range hood has the technical problems of being not attractive in style and large in occupied space although the air inlet is close to oil smoke and the smoking effect is good.

When the range hood stops working, the air inlet assembly 200 is hidden in the shell 100, so that the occupied space of the whole range hood is saved, and the integrity and the attractiveness of a kitchen are improved compared with a side-draft range hood; when the range hood operates, the extended air inlet assembly 200 enables the air inlet position to be closer to the cooking bench position where oil smoke is generated, and compared with a top suction type range hood, the range hood improves the oil smoke suction effect and prevents the oil smoke from escaping. The utility model relieves the attractive appearance of the ceiling type range hood, but the ceiling type range hood is easy to touch the head, and the air inlet is far away from the oil smoke, thus the smoke absorbing effect is poor; the side-draft range hood has the technical problems of being not attractive in style and large in occupied space although the air inlet is close to oil smoke and the smoking effect is good.

Exemplarily, the range hood in the embodiment has an operating state and a closing state when in operation: when the range hood is in a working state, as shown in fig. 3, the air intake assembly 200 extends out of the housing 100 from the telescopic opening 110 and is exposed out of the air inlet, and the extension of the air intake assembly 200 reduces the height of the air inlet, so that the oil smoke absorption efficiency of the range hood is increased; when the range hood is in the closed state, as shown in fig. 4, the air intake assembly 200 is retracted into the casing 100, so that the occupied space of the range hood is saved, and the overall appearance of the kitchen is beautified.

When the air intake assembly 200 is switched between the operating state and the closed state, that is, the air intake assembly 200 extends out of the expansion port 110 and exposes the air inlet, or the air intake assembly 200 retracts into the expansion port 110 and hides the air inlet, so the lifting assembly 300 is disposed at a corresponding position of the expansion port 110. For example, in the embodiment, the expansion joint 110 is disposed below the housing 100, and the lifting assembly 300 is disposed in the housing 100 at a position above the expansion joint 110.

In this embodiment, as shown in fig. 2, the intake assembly 200 includes a main body 210 and a partition 220, and the intake includes a first intake vent 230 and a second intake vent 240; a cavity is formed in the main body 210, the partition plate 220 is disposed in the cavity to divide the cavity into a first air duct 250 and a second air duct 260, the first air inlet 230 is communicated with the first air duct 250, and the second air inlet 240 is communicated with the second air duct 260.

Preferably, the partition plate 220 is disposed at the middle position of the main body 210, and divides the inner cavity of the main body 210 into a left portion and a right portion which are not communicated with each other, have the same cross-sectional shape and the same area, and respectively correspond to a left cooking bench and a right cooking bench of a gas stove below: the first air duct 250 is arranged at the left side of the partition plate 220, and the first air inlet 230 communicated with the first air duct is arranged above the left cooking bench; the second air duct 260 is disposed at the right side of the partition 220, and the second air inlet 240 communicated with the second air duct is disposed above the right cooking bench.

Compared with the range hood with only one air inlet channel, the double-air-channel design of the utility model can improve the negative pressure of the air outlet, realize the centralized guiding of the negative pressure area and enhance the smoking effect on one hand; on the other hand, because the left air inlet channel and the right air inlet channel are completely separated, the oil smoke can not generate secondary flow due to sudden change of the flow channel in the process of being sucked, the loss of flow force is reduced, and the smoking efficiency is improved.

Compare with current two inlet air channel's side suction type range hood, the utility model discloses a range hood organism volume is littleer, and is more pleasing to the eye, and need not to set up two actuating mechanism, has reduced range hood's cost and complexity, has reduced the production of noise.

Further, as shown in fig. 2, the air intake assembly 200 further includes a cover plate 270, and the cover plate 270 is rotatably connected to the main body 210 or the partition plate 220; the main body 210 is provided with a first air outlet 290 and a second air outlet 291, the first air outlet 290 is communicated with the first air duct 250, and the second air outlet 291 is communicated with the second air duct 260; the cover 270 is used to open the first outlet 290 and close the second outlet 291; or the second outlet 291 is opened and the first outlet 290 is closed; or both the first outlet port 290 and the second outlet port 291 are opened.

Specifically, the range hood is divided into three modes when in use: when a user uses the left cooking bench, the first air outlet 290 can be opened only, and the second air outlet 291 is closed, so that oil smoke enters the range hood only from the first air duct 250 above the left cooking bench; when the user uses the right cooking bench, the second air outlet 291 can be opened only, and the first air outlet 290 is closed, so that the oil smoke enters the range hood only from the second air duct 260 above the right cooking bench; when both cooking benches are used or a large amount of oil smoke is generated during cooking and a single air duct cannot completely absorb the oil smoke, a user can open the first air outlet 290 and the second air outlet 291 simultaneously, and the oil smoke can enter the range hood from the two air ducts at the moment.

When the range hood opens only the first air outlet 290 and closes the second air outlet 291, the cover plate 270 rotates rightwards to cover the top of the second air duct 260, and the second air duct 260 is closed; when the range hood opens only the second air outlet 291 and closes the first air outlet 290, the cover plate 270 rotates left to cover the top of the first air duct 250, and closes the first air duct 250; when the first outlet port 290 and the second outlet port 291 are both opened, the cover 270 is erected above the partition 220 and is located between the two air ducts.

Under the condition, when only one air duct is used, the complete separation of the left air duct and the right air duct effectively avoids the turbulent flow phenomenon caused by the sudden change of the flow channel in the rising process of the oil smoke, thereby reducing the loss of flow force, improving the smoking efficiency and playing the role of reducing noise; when the cover 270 is located at the middle position and both air ducts are used, the middle partition 220 can effectively prevent the air ducts on the left and right sides from colliding with each other when entering the fan 400, so as to generate turbulence.
