Embodiment 1

[0107] In the air curtain range hood described in this embodiment, the working area includes at least a part of the air suction range of the air suction port of the air curtain range hood, and the non-working area includes the upper surface of the air curtain range hood. Side and / or front side and / or left side and / or right side and / or lower side and at least a part of each of the above positions.

[0108] Through the air curtain range hood introduced in this embodiment, the working area and the non-working area are defined. Divide the environment around the range hood into at least two parts. The vicinity of the air suction port is taken as the working area. This position is the suction range of the range hood. The gas at this position is sucked into the range hood to a large extent. The gas here can represent the target gas composition of the range hood.

[0109] Further, the air curtain range hood introduced in this embodiment includes a fan device for generating airflow. ...

Embodiment 2

[0111] The difference between the air curtain range hood described in this embodiment and the above embodiments is that: the adjustment basis of the control device is the data generated at the same time by the air curtain device and / or the gas condition acquisition device. Preferably, the data is real-time data, and the adjustment is real-time adjustment.

[0112] Or, the adjustment of the control device is based on the data generated in the same time period as the air curtain device and / or the gas condition acquisition device. Preferably, the data is a calculated value within a specified time, and the adjustment is an intermittent adjustment. Further preferably, the specified time includes the time automatically obtained by the device and / or the time set by the user.

[0113] With the air curtain range hood introduced in this embodiment, the data acquired by the gas condition acquisition device can be acquired in real time, and the control basis of the control device can be ...

Embodiment 3

[0115] The difference between the air curtain range hood described in this embodiment and the above embodiment is that: the first gas condition acquisition device generates first data according to the gas in the working area, and the control device adjusts the first data according to the first data. It will display the working status of the air curtain device and / or prompt the acquisition result and / or prompt the operation suggestion. Preferably, when the first data reaches / does not reach the corresponding threshold, the air curtain device is controlled to be turned on / off and / or prompts for obtaining results and / or prompts for operation suggestions.

[0116] With the air curtain range hood introduced in this embodiment, when the first data alone is used as the investigation basis, if the first data reaches the corresponding threshold (corresponding to the situation where the oil smoke is relatively serious), regardless of the second data, it is selected to turn on the fan. sc...

Abstract

The invention discloses an air curtain extractor hood. The air curtain extractor hood comprises an air curtain device for forming an air curtain, gas condition obtaining devices and a control device,wherein the gas condition obtaining devices comprise the first gas condition obtaining device for obtaining the gas condition in a working area of the air curtain extractor hood, and the second gas condition obtaining device for obtaining the gas condition in a non-working area of the air curtain extractor hood, and the control device adjusts the working state of the air curtain device and/or prompts a judgment result of the working state of the air curtain device and/or prompts operation recommendations according to data obtained by the gas condition obtaining devices. According to the air curtain extractor hood, the starting condition of the air curtain device is improved, the air curtain device is started only when needed, and user experience is enhanced.

Description

technical field [0001] The invention belongs to the field of kitchen air purification equipment, and in particular relates to an air curtain range hood. Background technique [0002] Kitchen purification equipment in the prior art mostly relies on air flow to improve the kitchen gas environment. At present, most of this kind of equipment are range hoods and related improved equipment. However, these range hoods are all passive air suction devices, and their range hoods have a certain distance from the cooker that produces the oil fume, so the oil fume with a certain kinetic energy that is generated instantaneously during cooking cannot be completely eliminated. In order to solve the above problems, various kitchen purification equipment manufacturers have made improvements by changing the height and working power of the range hood, which has improved the effect of the range hood, but still cannot solve the problem of the overflow of the range hood from the periphery of the ...
