Problems solved by technology

However, because the smoke deflector in the prior art can only guide part of the oil fume to the air inlet of the range hood, the smoke exhaust efficiency of the range hood is low for the oil fume with a high concentration.

Embodiment 1

[0045] In order to ensure that the range hood meets different smoke exhaust requirements in different application scenarios, an embodiment of the present invention provides a range hood. figure 1 A front view of the range hood provided by the embodiment of the present invention is shown. figure 2 A side view of the range hood provided by the embodiment of the present invention is shown. image 3 A schematic structural diagram of the range hood is shown when the smoke guide 200 is at the first position. Figure 4 It shows the working principle diagram of the range hood when the smoke guide is in the first position. Figure 5 A schematic structural view of the range hood is shown when the smoke guide 200 is in the second position. see Figure 1-Figure 5The range hood provided by the embodiment of the present invention includes a smoke collecting hood 100 having a smoke collecting air inlet 110 and a smoke guide 200 arranged under the smoke collecting hood 100 . Wherein, the...

Embodiment 2

[0079] In order to intelligently control the range hood and simplify the operation process of the range hood, an embodiment of the present invention provides a control method for the range hood. Figure 15 A flow chart of the range hood control method is shown. see Figure 15 , the above range hood control method includes:

[0080] Step S100: Determine whether the oil fume concentration reaches a concentration threshold.

[0081] When the oil fume concentration reaches the concentration threshold, it means that the oil fume concentration is relatively high, and the smoke exhaust and smoke collection efficiency of the range hood needs to be improved, and step S200 is executed at this time.

[0082] When the concentration of soot does not reach the concentration threshold, it means that the concentration of soot is relatively small, and step S300 is executed at this time.

[0083] Step S200: Put the smoke guide 200 at the second position.

[0084] Step S300: Put the smoke gu...

Embodiment 3

[0163] In order to implement the above range hood control method, see Figure 26 , the embodiment of the present invention provides a range hood control device. The range hood control unit includes:

[0164] A processor 400, the processor 400 is configured to determine whether the oil smoke concentration reaches a concentration threshold.

[0165] When the oil smoke concentration reaches the concentration threshold, the processor 400 is further configured to place the smoke guide 200 at the second position.

[0166] When the oil smoke concentration does not reach the concentration threshold, the processor 400 is further configured to place the smoke guide 200 at the first position.

[0167] The beneficial effect of the range hood control device provided by the embodiment of the present invention is the same as that of the above-mentioned range hood control method, and will not be repeated here.

[0168] As a possible implementation, see Figure 26 , the above range hood co...

Abstract

The invention discloses a range hood, and relates to the technical field of a range hood. The range hood is used for meeting different fume discharge requirements in different application scenes. The range hood comprises an exhaust fume collecting hood with an exhaust fume collecting air inlet and an exhaust fume guide piece arranged below the exhaust fume collecting hood. The interior of the exhaust fume guide piece is of a hollow structure, a fume guide air inlet and a fume guide air outlet are formed in the exhaust fume guide piece, and the fume guide air inlet is communicated with the fume guide air outlet; the exhaust fume guide piece is capable of moving between a first position and a second position, and when the exhaust fume guide piece is located at the first position and the second position, the fume guide air outlet communicates with the exhaust fume collecting air inlet; and when the exhaust fume guide piece is located at the second position, the height of the fume guide air inlet is lower than that of the fume guide air inlet when the exhaust fume guide piece is located at the first position.

Description

technical field [0001] The invention relates to the technical field of range hoods, in particular to a range hood. Background technique [0002] The range hood is a kitchen appliance that purifies the kitchen environment. It is installed on the top of the kitchen stove, which can quickly remove the exhaust gas from the stove and the harmful oil fumes produced during the cooking process, reduce indoor air pollution, purify the air, and have the function of anti-virus and explosion-proof safety guarantee. [0003] In order to effectively protect users from the hazards of cooking fumes, the design of range hoods currently on the market will take the smoke exhaust effect as an important assessment index. In the prior art, in order to improve the smoke-exhausting and smoke-contracting effect of the range hood, a smoke guide plate is added on the range hood, and the position and angle of the smoke guide plate can be adjusted according to the concentration of the lampblack. Howev...
