Embodiment 1

[0109] In the air curtain range hood of this embodiment, the gas condition acquisition device includes a lampblack obtaining module for detecting the content of lampblack. The gas condition acquisition device is used to detect the atmosphere composition in the surrounding environment. When detecting that the oily smoke content in the atmosphere composition in the surrounding environment reaches the corresponding threshold, the device automatically turns on the air curtain device to avoid oily smoke affecting users. Or, the range hood prompts the user with the obtained results or operation suggestions for the user. The obtained results include the content of the detected oil fume, the production location of the oil fume, the temperature of the oil fume, and so on. The operation suggestions include prompting the user to turn on the air curtain device, prompting the user to turn on the impurity removal unit, the opening angle / wind speed / flow rate / level of the air curtain device, ...

Embodiment 2

[0113] The difference between the air curtain range hood described in this embodiment and the foregoing embodiment is that the atmosphere detection unit controls the opening / closing of the air curtain device when it detects that the surrounding air contains / no oil smoke. Or, when the atmosphere detection unit detects that the ambient gas soot content reaches / does not reach the threshold, the air curtain device is controlled to turn on / off. Two conditions for opening the air curtain are adjustable. Can be set by the user. The range hood can prompt the user to select the opening condition of the air curtain when the device is turned on. It can be seen that the opening conditions of the first wind curtain are more sensitive and provide comprehensive protection for users. The second type of air curtain opening condition requires reaching the threshold, which is relatively insensitive, but can avoid repeated opening of the air curtain device and avoid increasing the workload of th...

Embodiment 3

[0115] The difference between the air curtain device described in this embodiment and the foregoing embodiment is that it includes a decontamination unit that purifies the gas in the internal air duct. The impurity removal unit can be used to remove oily smoke, particles and other substances in the air duct of the air curtain device. In order to ensure the cleanliness of the air curtain airflow generated by the air curtain device, and improve the user experience. Moreover, the impurity removal unit in this embodiment is not turned on in real time and performs the impurity removal function. The cleaning unit includes a cleaning unit switch for controlling the working state of the cleaning unit. The working status of the trash removal unit includes: the on and off status of the trash removal unit.

[0116] Further, the switch of the cleaning unit in this embodiment is a manual switch and / or an automatic switch. When the range hood judges that it is necessary to turn on the impur...

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 controls a working state of the air curtain device and / or prompts gas conditions of the surrounding environment and / or prompts operation suggestions through the gas conditions in the surrounding environment of the air curtain range hood. According to the introduced air curtain range hood, opening conditions of the air curtain are improved, the air curtain is opened onlyas needed, and the user experience is improved.

Description

Technical field [0001] The invention belongs to the field of kitchen air purification equipment, and specifically relates to an air curtain range hood. Background technique [0002] The kitchen purification equipment in the prior art mostly relies on air flow to improve the gas environment of the kitchen. At present, most of this type of equipment is range hoods and related improvements. There are many types of models, including double cylinders, single cylinders, hoods, upper suction, and lower suction. However, these range hoods are passive air suction devices, and the range hood has a certain distance from the cooker that generates the range hood, so the range hood that is generated instantaneously during cooking and has a certain kinetic energy cannot be completely eliminated. In order to solve the above-mentioned problems, various kitchen purification equipment manufacturers have improved the range hood height and working power to improve the effect of oil smoke, but still ...
