Embodiment 1

[0050] combine Figure 1-Figure 7 As shown, the range hood provided in this embodiment includes:

[0051] Smoke collecting hood 5;

[0052] The main oil screen 1 is at least partially hollowed out to form a smoke passage, and the main oil screen 1 is movably connected with the smoke collecting hood 5; and

[0053] The smoke guide plate 2 is configured as a plate structure, and the smoke guide plate 2 is movably connected with the main oil net 1;

[0054] When the main oil screen 1 is in the initial state, it is attached to the top surface of the smoke collecting hood 5; when the main oil screen 1 is in the working state, it is set at an angle to the top surface of the smoke collecting hood 5;

[0055] The smoke guide plate 2 covers the main oil screen 1 in the initial state; the smoke guide plate 2 is set at an angle to the main oil screen 1 in the working state.

[0056] Preferably, the main oil screen 1 is provided with several grilles or the main oil screen 1 is arranged i...

Embodiment 2

[0106] This embodiment provides a method for controlling a range hood, including:

[0107] Obtain the oil fume concentration;

[0108] The position state of at least one of the main oil screen, the smoke deflector, and the auxiliary oil screen is controlled based on the oil smoke concentration.

[0109] The control of the position state of at least one of the main oil net, the smoke deflector, and the auxiliary oil net based on the oil smoke concentration includes:

[0110] When the oil fume concentration is greater than the preset concentration, at least one of the main oil screen, the smoke deflector, and the auxiliary oil screen is controlled to move from the initial state position to the working state position; and at the same time, the fan is controlled to run.

[0111] The soot concentration is acquired by the smoke sensor module 11 .

[0112] As a variant, when the range hood is turned on or off, the movement of the folding plate will be started or closed synchronousl...

Abstract

The invention relates to the technical field of kitchen appliances, in particular to a range hood and a control method thereof. The range hood comprises a lampblack collecting hood, a main oil screen and a lampblack guide plate, wherein at least part of the main oil screen is hollowed out to form a lampblack passing channel, and the main oil screen is movably connected with the lampblack collecting hood; the lampblack guide plate is of a plate-shaped structure, and the lampblack guide plate is movably connected with the main oil screen; when the main oil screen is in an initial state, the main oil screen is attached to the top surface of the lampblack collecting hood; when the main oil screen is in a working state, the main oil screen and the top surface of the lampblack collecting hood are arranged at an angle; when the lampblack guide plate is in the initial state, the main oil screen is covered; and when the lampblack guide plate is in the working state, the lampblack guide plate and the main oil screen are arranged at an angle. According to the range hood, when the main oil screen is in the working state, the main oil screen and the top surface of the lampblack collecting hood are arranged at an angle, so that the lampblack filtering effect can be improved compared with a mode that a main oil screen is parallel to the top surface of a lampblack collecting hood, and the main oil screen is configured to be in an inclined state so that the sliding speed of oil on the main oil screen can be increased.

Description

technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a range hood and a control method thereof. Background technique [0002] Range hoods have become one of the indispensable kitchen equipment in modern families. Common range hoods include top-suction and side-suction types. widely. However, compared with the side-suction range hood, the top-suction range hood has a longer distance for the oil fume to enter the fan because the air inlet is far away from the stove, and it takes a longer time to reach the fan. The oily fume is easy to escape; in addition, the oil screen of the conventional top suction range hood has poor oil fume filtering effect, and the separation degree of grease is low. There is a certain proportion of grease that is sucked into the fan and solidified on the fan. , resulting in increased noise of the range hood and increased cleaning difficulty. Contents of the invention [0003] Therefore, the te...
