Embodiment 1

[0041] Such as figure 1 , Figure 6 The embodiment shown is a range hood with human body induction function, which includes a smoke hood 1 with an inclined panel 2 that gradually slopes forward and upward from bottom to top, an air suction port and an oil baffle 3 on the inclined panel , the inclined panel and the oil baffle are parallel and there is an air guiding distance between them, the oil cup 4 located at the lower part of the smoke hood can be moved to the lower edge of the inclined panel and the oil baffle, and the smoke hood is provided with a drive oil The power mechanism for cup telescopic and lifting;

[0042] Such as image 3 As shown, there are three strip-shaped heating films 6 arranged up and down inside the inclined panel and the oil baffle, and a temperature sensor 7 and two infrared sensors 8 for detecting power-on and power-off signals are arranged on the smoking hood. A controller 10 and a memory 11 are arranged inside the cover; the controller is elec...

Embodiment 2

[0054] Embodiment 2 includes all the structures and steps of Embodiment 1. Embodiment 2 also includes a humidity sensor 24 on the air suction port, and the humidity sensor is electrically connected to the controller.

[0055] Also include the following steps:

[0056] The humidity threshold C is set in the memory, and the humidity sensor detects the humidity at the suction port during the working process of the hood;

[0057] When the detected humidity value≤C, step 200 in embodiment 1 is replaced by the following steps:

[0058] When the detected temperature value is <T and the start-up time is ≥L, the controller controls each piece of strip-shaped heating film to be heated simultaneously; the oil droplets accumulated on the inclined panel and the oil baffle gradually move downward and drop into the oil cup. C = 45%.

Embodiment 3

[0060] Embodiment 3 includes all structures and step parts of Embodiment 1, and Embodiment 3 also includes such as image 3 The shown oil cup is provided with a surrounding wall heating film 41 and a bottom wall heating film 42, a heating indicator light 43 is provided on the oil cup, an oil cup heating key 14 is provided on the smoke hood, the surrounding wall heating film, the bottom wall heating film, the oil Both the cup heating key and the heating indicator light are electrically connected to the controller; the following steps are also included:

[0061] There is a heating time threshold K in the memory; when there is a lot of oil in the oil cup and the oil needs to be poured out, press the oil cup heating button, the controller controls the heating of the surrounding wall heating film and the bottom wall heating film, and the heating indicator lights When it is on, the controller calculates the length of heating time. When the length of heating time reaches K, the contr...

Abstract

The invention discloses an extractor hood with a human body induction function and a control method. The extractor hood comprises a smoke sucking cover, an air sucking opening, an oil baffle plate, an oil cup and multiple vertically-arranged strip-shaped heating films. The smoke sucking cover is provided with an inclined panel which gradually inclines to the portion above the front portion from bottom to top, and the air sucking opening and the oil baffle plate are arranged on the inclined panel. The inclined panel is parallel to the oil baffle plate, and an air guide interval is formed between the inclined panel and the oil baffle plate. The oil cup is arranged on the lower portion of the smoke sucking cover and can move below the lower edge of the inclined panel and the lower edge of the oil baffle plate. A power mechanism capable of driving the oil cup to stretch out, draw back, ascend and descend is arranged on the smoke sucking cover. The strip-shaped heating films are arranged in the inclined panel and the oil baffle plate. The extractor hood has the beneficial effects that oil drops flowing down from the oil baffle plate and the inclined panel can be better collected and wiped away, the liquidity of the oil drops is effectively improved, and the situation that the oil drops directly fall on a cooking bench is avoided.

Description

technical field [0001] The invention relates to the technical field of kitchen equipment, in particular to a range hood with a human body sensing function capable of intelligently controlling the collection of oil droplets in the range hood and a control method. Background technique [0002] The range hood is an indispensable kitchen equipment in modern families. The oil fumes generated during cooking and frying in the kitchen can be exhausted to the outside through the range hood to keep the room clean and avoid oil accumulation in the kitchen. [0003] However, due to the large change in the ambient temperature, when the temperature is low, the oil droplets adsorbed on the range hood often cannot flow into the oil cup smoothly, leaving unsightly oil stains on the range hood, and the oil When there are too many stains, the oil droplets will fall directly on the stove, which is not hygienic and makes it difficult to clean the kitchen utensils. [0004] At present, the switc...
