Problems solved by technology

However, the air curtain device needs the air curtain fan to provide airflow, which obviously increases the equipment noise and energy consumption of the equipment, and the separate control system for the air curtain device also increases the system burden and control burden of the equipment

Embodiment 1

[0117] For the air curtain range hood introduced in this embodiment, the gas condition acquisition device includes a soot acquisition module for detecting the content of soot. The gas condition acquisition device is used to detect the atmosphere composition in the surrounding environment. When it is detected that the oil fume content in the atmosphere in the surrounding environment reaches the corresponding threshold, the device will automatically turn on the air curtain device to prevent the oil fume from affecting the user. Alternatively, the range hood prompts the user with a detection result or an operation suggestion for the user. The detection results include the detected oil fume content, the production location of the oil fume, the temperature of the oil fume, and so on. The operation suggestions include prompting the user to open the air curtain device, prompting the user to open the impurity removal unit (recorded in subsequent embodiments), the opening angle / wind s...

Embodiment 2

[0121] The difference between the air curtain range hood introduced in this embodiment and the above embodiments is that the gas condition acquisition device is used to detect the gas condition in the air duct of the air curtain device. When it is detected that the oil fume content in the atmosphere in the surrounding environment reaches the corresponding threshold, the device will automatically turn on the air curtain device to prevent the oil fume from affecting the user. Alternatively, the range hood prompts the user with a detection result or an operation suggestion for the user. The detection results include the detected oil fume content, the production location of the oil fume, the temperature of the oil fume, and so on. The operation suggestions include prompting the user to open the air curtain device, prompting the user to open the impurity removal unit (recorded in subsequent embodiments), the opening angle / wind speed / flow rate / level of the air curtain device, the op...

Embodiment 3

[0124] The difference between the air curtain range hood introduced in this embodiment and the above embodiments is that the range hood includes a primary atmosphere acquisition unit for detecting the gas condition of the surrounding environment and / or a device for detecting the gas condition in the air duct of the air curtain device Secondary atmosphere acquisition unit; the two detection units are respectively provided with an oil fume acquisition module for detecting oil fume content and / or a moisture acquisition module for detecting moisture content.

[0125] Wherein, when the first-level atmosphere acquisition unit detects that the ambient gas contains / has no oil smoke, it controls the opening / closing of the air curtain device. Alternatively, when the primary atmosphere acquisition unit detects that the soot content of the ambient gas reaches / does not reach the threshold, it controls the air curtain device to be turned on / off. Two conditions for opening the air curtain ar...

Abstract

The invention discloses an air curtain range hood, which includes an air curtain device and a gas condition acquisition device. The air curtain device is used for forming an air curtain, and the gas condition acquisition device is used for obtaining the surrounding environment and / or equipment internal gas conditions, is connected with the air curtain device, and controls a working state of the air curtain device and / or prompts obtained results and / or prompts operation suggestions according to the results obtained by the gas condition acquisition device. According to the introduced air curtainrange hood, opening conditions of the air curtain are improved, the air curtain is opened only as needed, and the user experience is improved.

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 ...
