Problems solved by technology

However, the range hoods in the prior art can only adjust the oil absorption efficiency through the power of the fan because the oil absorption area does not change, which cannot meet people's needs for different oil absorption areas and different oil absorption efficiency according to different cooking methods or different heat conditions.

Embodiment 1

[0026] see Figure 1-Figure 6 , the range hood of this embodiment includes:

[0027] Range hood body 1;

[0028] The baffles 2 arranged on both sides of the range hood body 1 can be deployed to both sides of the range hood body 1 respectively;

[0029] A rotary drive mechanism connected to the baffle 2 for driving the baffle 2 to rotate to adjust the current degree of expansion of the baffle.

[0030] Optionally, the range hood also includes an automatic control system that controls the rotary drive mechanism to drive the baffle 2 to rotate;

[0031] The automatic control system includes:

[0032] The sensor 7 is arranged on the range hood body 1, and is used to detect and send the amount of oil fume information;

[0033] The comparator 8 stores the preset threshold value of the oil smoke amount information, is connected to the sensor 7, and is used to receive the oil smoke amount information sent by the sensor 7, compare it with the preset threshold value, and send the co...

Embodiment 2

[0052] see Figure 7 , this embodiment provides a control method for the range hood described in Embodiment 1, comprising the following steps:

[0053] S10: Obtain the current amount of oil fume in the space where the range hood body is located;

[0054] S20: Generate a rotation control signal according to the oil fume amount information;

[0055] S30: Send the rotation control signal to the rotation driving mechanism, for instructing the rotation driving mechanism to drive the baffle to rotate to adjust the current degree of expansion of the baffle.

[0056]Optionally, the acquiring the current oil smoke amount information in the space where the range hood body is located includes: detecting the current oil smoke amount information in the space where the range hood body is located by the sensor and sending it to the comparator; according to the oil smoke amount information Generating the rotation control signal includes: a comparator storing a preset threshold value of the ...

Abstract

The invention discloses a range hood and a control method thereof. The range hood comprises a range hood body, a baffle plate, and a rotation driving mechanism which is used to drive the baffle plate to rotate; wherein the rotation driving mechanism drives the baffle plate to rotate so as to achieve the opening and closing of the baffle plate. In this range hood, the baffle plate can be opened or closed, when the oil smoke amount is large, the baffle plate can be opened so as to prevent the smoke oil from diffusing to the upper space over the two sides of the range hood body, thus the oil absorbing efficiency is improved; when the oil smoke amount is small, the baffle plate can be closed; so that the range hood can satisfy different requirements on oil-absorbing efficiency during the cooking process, and has a strong adaptability.

Description

technical field [0001] The invention relates to a range hood, in particular to a range hood and a control method thereof. Background technique [0002] Most of the existing range hoods have no change in the oil absorption area. When cooking, the range hood is turned on, and when not cooking, the range hood is turned off. In the process of cooking, the user will involve different cooking methods, such as porridge, stir-frying, frying, etc., and will also use different heats, and the amount of oily smoke released by different cooking methods or different cooking heats is different. In the same way, different oil absorption areas and oil absorption efficiencies are required so that the oil fumes will not spread into the living room. And the range hood in the prior art, because the oil-absorbing area can not change, can only adjust the oil-absorbing efficiency by the power of blower fan, can not satisfy people's different cooking methods or different heat requirements for diffe...
