Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

A range hood 12 according to an embodiment of the present invention is described below with reference to fig. 1 to 41.

As shown in fig. 1 to 41, a range hood 12 according to an embodiment of the present invention includes: a cigarette maker housing 121, a drive member 16 and a panel member 15. The smoke exhaust ventilator casing 121 is provided with a smoke outlet 1211b, a first smoke inlet 1211a and a second smoke inlet 1211c, the smoke exhaust ventilator casing 121 is provided with a smoke passage 1211 therein, the first smoke inlet 1211a and the second smoke inlet 1211c can communicate with the smoke outlet 1211b through the smoke passage 1211, and the second smoke inlet 1211c is located above the first smoke inlet 1211a in the vertical direction shown in fig. 11.

The cigarette machine casing 121 is provided with a driving component 16, the driving component 16 is connected with the panel component 15, the driving component 16 can drive the panel component 15 to move from a first position to a second position, the driving component 16 can also drive the panel component 15 to move from the second position to the first position, when the panel component 15 is located at the first position, the panel component 15 can shield the second lampblack inlet 1211c, and when the panel component 15 is located at the second position, the panel component 15 does not shield (avoid) the second lampblack inlet 1211 c.

Alternatively, when the panel member 15 is located at the first position, the panel member 15 may shield a part of the second smoke inlet 1211c, or the panel member 15 may shield the second smoke inlet 1211c entirely.

Alternatively, the hood 12 may be adapted to a light oil smoke cooking scenario and a heavy oil smoke cooking scenario, when the panel member 15 is located at the first position, since the panel member 15 completely or partially shields the second smoke inlet 1211c, at this time, the smoke generated by cooking can only enter the smoke passage 1211 from the first smoke inlet 1211a, or the smoke generated by cooking can enter the smoke passage 1211 from the first smoke inlet 1211a and the unblocked part of the second smoke inlet 1211c, and therefore, when the panel member 15 is located at the first position, the hood 12 may be adapted to the light oil smoke cooking scenario.

When the cooking scenario is a heavy oil smoke cooking scenario, the driving member 16 may drive the panel member 15 to move from the first position to the second position, and when the panel member 15 is located at the second position, the panel member 15 does not shield the second oil smoke inlet 1211c, at this time, oil smoke generated by cooking can enter the oil smoke channel 1211 from the first oil smoke inlet 1211a and can enter the oil smoke channel 1211 from the second oil smoke inlet 1211c, so as to increase the area of the oil smoke inlet of the range hood 12 and improve the oil smoke extraction efficiency of the range hood 12, and therefore, when the panel member 15 is located at the second position, the range hood 12 may be suitable for the heavy oil smoke cooking scenario.

It should be understood that no matter the panel member 15 is located at the first position or the panel member 15 is located at the second position, the panel member 15 does not block the first smoke inlet 1211a, that is, no matter what cooking scene is, the smoke generated by cooking can enter the smoke passage 1211 from the first smoke inlet 1211 a.

Among the prior art, smoke ventilator's panel member can not be through the oil pumping cigarette function of change position smoke ventilator 12 when satisfying different culinary art scenes to can lead to smoke ventilator 12's use inconvenient, can reduce user's use and experience.

In the present application, the panel member 15 is driven by the driving member 16 to move between the first position and the second position, when the panel member 15 is located at the first position, the cooking fumes can only enter the fume passage 1211 from the first fume inlet 1211a, or the cooking fumes can enter the fume passage 1211 from the first fume inlet 1211a and the portion of the second fume inlet 1211c that is not shielded, so that the range hood 12 can be suitable for the light fume cooking scenario.

When the driving member 16 drives the panel member 15 to move from the first position to the second position, the cooking fumes generated by cooking can enter the fume passage 1211 from the first fume inlet 1211a and also enter the fume passage 1211 from the second fume inlet 1211c, so that the range hood 12 is suitable for heavy oil fume cooking scenes, and the range hood 12 is convenient and reliable to use, and the use experience of a user can be improved.

From this, through setting up driver part 16, can drive panel part 15 through driver part 16 and move between primary importance and second place to can satisfy the oil smoke pumping function of smoke ventilator 12 when different culinary art scenes, and then can make smoke ventilator 12's convenient to use, reliable, can improve user's use and experience.

As some embodiments of the utility model, the motion of drive assembly 16 drive panel part 15 between first position and second position can be by user manual control, optionally, can set up control button on cigarette machine casing 121, when the user needs to remove panel part 15 to the second position, the user can press control button, after the user pressed control button, drive assembly 16 can drive panel part 15 and move to the second position from the first position, and, when the user needs to remove panel part 15 to the first position, the user also can press control button, after the user pressed control button, drive assembly 16 can drive panel part 15 and move to the first position from the second position.

Further, a smoke sensor may be disposed in the smoke exhaust ventilator 12, the smoke sensor may automatically detect a smoke amount or a smoke concentration generated by cooking at this time, and after the smoke sensor detects that the smoke amount or the smoke concentration generated by cooking at this time exceeds a preset threshold, the driving component 16 may drive the panel component 15 to move from the first position to the second position to improve the smoke exhaust efficiency of the smoke exhaust ventilator 12. And, after the oil smoke sensor detects that the oil smoke volume or the oil smoke concentration that the cooking produced at this moment is less than preset threshold, driver component 16 can drive panel part 15 and move to the first position from the second position, and optionally, preset threshold can be according to user's needs preset, and the degree of automation that smoke ventilator 12 can be improved to this setting.

Furthermore, the control mode of the panel part 15 may be a combination of the above two modes, and the priority of the user manually controlling the movement of the panel part 15 is higher than the priority of the automatic detection of the soot sensor, so that the automation degree of the range hood 12 can be further improved, and the user can have better use experience.
