As shown in fig. 1 and 2, the present embodiment provides a range hood, which includes a hood housing, a first driving part 3, a second driving part 4, a detection module, and a control module.

Referring to fig. 1, a first air duct 1 and a second air duct 2 which are independent from each other are arranged in the housing of the range hood. The first driving member 3 is disposed in the first air duct 1, and the second driving member 4 is disposed in the second air duct 2. The detection module is used for detecting the oil smoke concentration in a kitchen and the air inflow of the first air duct 1. The control module controls the opening and closing of the first driving piece 3 and the second driving piece 4 according to the data result detected by the detection module. First wind channel 1 and second wind channel 2 are independent for each other do not influence between the two, but first driving piece 3 and second driving piece 4 independent operation realize different modes of discharging fume.

Specifically, when there is the oil smoke in the kitchen, and the oil smoke is less, detection module detects that oil smoke concentration is less than first default, and control module just controls first driving piece 3 and starts, and the oil smoke is discharged through first wind channel 1, realizes that the kitchen discharges fume. When the oil smoke is more in the kitchen, the detection module detects that the oil smoke concentration reaches the second preset value, the control module controls the second driving piece 4 to be started, the oil smoke is discharged through the first air duct 1 and the second air duct 2 (refer to fig. 1, the arrow direction in the figure is the air flow direction), and the kitchen smoke discharging effect is improved. If the detection module detects that the air inflow of the first air duct 1 is smaller than the air inflow preset value, it indicates that the air inflow of the first air duct 1 is insufficient, at the moment, the control module controls the second driving piece 4 to reversely rotate, the second air duct 2 becomes an air inflow channel, outdoor air enters a kitchen through the second air duct 2 (see fig. 3) to supplement air for the first air duct 1, and therefore the smoke exhaust effect of the first air duct 1 is improved. That is to say, the lampblack absorber of this embodiment can realize three kinds of modes of discharging fume according to different conditions, effectively solves the not thorough problem of kitchen oil smoke discharging fume.

Referring to fig. 1, a smoke suction port of a first air duct 1 is opposite to a kitchen range and is located above the kitchen range. The first air channel 1 is located on the front side of the range hood, the second air channel 2 is located on the rear side of the range hood, and a smoke suction port of the second air channel 2 faces a kitchen range of a kitchen and is located on one side of the kitchen range. That is, in this embodiment, the first air duct 1 forms a top suction type smoke suction port, and the second air duct 2 forms a bottom suction type smoke suction port, so that the range hood has dual smoke suction ports, and can operate a corresponding smoke discharge mode according to actual conditions, thereby effectively improving smoke discharge effect.

As shown in fig. 1 and fig. 2, optionally, the first air duct 1 includes a first tube 11 and a second tube 12 connected to each other, the first driving member 3 is disposed in the first tube 11, a top end of the first tube 11 is a smoke exhaust port, an air outlet of the first driving member 3 is communicated with the smoke exhaust port, an air inlet of the first driving member 3 is communicated with the smoke exhaust port, and one end of the second tube 12 away from the first tube 11 is the smoke exhaust port. In this embodiment, the opening at the lower end of the second cylinder 12 is larger than the upper end, so that the smoke suction port of the first air duct 1 has a large enough area to cover the range on the cooking bench, and fully absorbs the oil smoke or water vapor generated during cooking.

Optionally, a first filter is provided in the second barrel 12 at the smoking orifice. The large granule impurity that carries in the first filter screen can the filtered oil cigarette avoids 1 internal suction plugs in first wind channel, leads to pipe blockage. Simultaneously can condense partial oil stain on the first filter screen to reduce the volume of condensing of oil stain in the first wind channel 1, make things convenient for the later stage to clear up.

Optionally, a heating device is disposed in the second air duct 2, and the heating device can heat the air in the second air duct 2. When the second air duct 2 is used as an air inlet passage to supply air to the first air duct 1, the temperature of outdoor air is low in cold winter, and if cold air is directly sucked into a kitchen, the temperature of the kitchen can be reduced, so that inconvenience is brought to a user. The heating device heats sucked air, the air is guaranteed to be supplied to the first air channel 1, meanwhile, the indoor temperature of a kitchen cannot be reduced, and the use experience is better.

Further, a second filter screen is arranged at the smoke suction opening of the second air duct 2. The second filter screen can filter the large granule impurity that carries in the oil smoke, avoids inhaling the plug in the second wind channel 2, leads to the pipe blockage.

Optionally, referring to fig. 1 and 2, the detection module includes a first sensor 51 and a second sensor 52, the first sensor 51 is disposed on an outer wall of the housing of the range hood for detecting the concentration of the oil smoke in the kitchen, and the second sensor 52 is disposed at an air inlet of the first air duct 1 for detecting the air intake amount of the first air duct 1. The control module judges and controls the first driving part 3 and the second driving part 4 according to the data obtained by the detection of the first sensor 51 and the second sensor 52, so that the range hood can realize different smoke discharging modes.

Preferably, the first sensor 51 may be a soot sensor capable of detecting the concentration of soot in the kitchen in real time. The second sensor 52 may be an air flow sensor capable of detecting the amount of air taken in at the air inlet of the first air duct 1.

In this embodiment, when the first sensor 51 detects that the concentration of the soot in the kitchen is greater than or equal to M1, the control module controls the first driving member 3 to start. M1 may be 0, i.e. no soot in the kitchen. For example, when only a steamer is used in a kitchen to cook food, only water vapor is generated in the kitchen, and at the moment, no oil smoke exists, so that only the first driving piece 3 needs to be opened, and the water vapor is discharged out of the room through the first air duct 1. M1 also can be a certain smog concentration value, and M1 shows that the oil smoke concentration in the kitchen is relatively small, and at this moment, the requirement of kitchen smoke exhaust can be met only by opening the first driving piece 3 and exhausting smoke through the first air duct 1, so that electric energy is saved. The value of M1 may be set according to user requirements.

When first inductor 51 detected the oil smoke concentration more than or equal to M2 in the kitchen (M1 < M2), control module controlled first driving piece 3 promptly and second driving piece 4 and started simultaneously, and the oil smoke can get into first passageway 1 and second passageway 2, carries out the binary channels and discharges fume, in time discharges the oil smoke in the kitchen, improves the smoke effect, and M2's value can be set for according to the user's demand. It should be noted that, when discharging smoke through two channels, it is necessary to ensure that the air intake amount of the first air duct 1 is sufficient.

Referring to fig. 3, if the second sensor 52 detects that the air intake amount of the first air duct 1 is smaller than N, the control module controls the second driving member 4 to rotate reversely, so that the second driving member 4 sends the outdoor air into the kitchen through the second air duct 2. The second air duct 2 becomes an air intake passage to supply air to the first air duct 1. The value of N is specifically set according to the needs of a user.

Of course, if the cooking is finished and the oil smoke in the kitchen is reduced, the first sensor 51 detects that the concentration of the oil smoke in the kitchen is less than M2, and the second sensor 52 detects that the air inflow of the first air duct 1 is enough, the control module controls the second driving member 4 to stop, only the first driving member 3 is kept to work, and the electric energy is saved.

In this embodiment, the first driving member 3 and the second driving member 4 are both motors. In other embodiments, the first and second drives 3, 4 may also be volute fans.

The lampblack absorber that this embodiment provided, its working process is as follows:

when a steamer or the like is used in a kitchen to generate light water vapor, the control module controls the first driving piece 3 to be started, and the water vapor is upwards discharged through the first air duct 1, namely, the range hood performs a one-way smoke exhaust mode;

when a large amount of oil smoke is generated during frying cooking in a kitchen and the first air channel 1 is sufficient in air inlet, the first sensor 51 detects that the concentration of the oil smoke in the kitchen is greater than M2, the control module controls the first driving piece 3 and the second driving piece 4 to be started simultaneously, and the oil smoke is discharged out of the kitchen through the first air channel 1 and the second air channel 2, namely, the range hood is used for strongly discharging the oil smoke through the two air channels;

when the second sensor 52 detects that the air inflow at the air inlet of the first air duct 1 is smaller than N, the air inflow of the first air duct 1 is insufficient, the control module controls the second driving piece 4 to rotate reversely, the second air duct 2 becomes an air inlet channel, outdoor air is introduced into a kitchen through the second air duct 2 to supply air to the first air duct 1, and the second air duct 2 is matched with the first air duct 1 to discharge smoke. Namely, the range hood carries out a circulating air supply mode. The range hood can operate three smoke exhaust modes according to different conditions.

It is to be noted that the foregoing description is only exemplary of the utility model and that the principles of the technology may be employed. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments illustrated herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the utility model. Therefore, although the present invention has been described in greater detail by the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the spirit of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
