Embodiment 1

[0102] In the air curtain range hood described in this embodiment, the working states of the impurity removal unit include: open and / or closed states. When the gas condition acquisition device acquires the presence / absence of oil fume, it controls the opening / closing of the impurity removal unit and / or prompts the gas condition of the air duct and / or prompts for operation suggestions.

[0103] Alternatively, when the gas condition acquisition device acquires that the concentration of oil fume reaches a corresponding threshold, it controls the opening / closing of the impurity removal unit and / or prompts the gas condition of the air duct and / or prompts for operation suggestions.

[0104] Further, the air curtain range hood described in this embodiment includes an air duct of the air curtain device inside. Preferably, the acquisition method includes detection.

[0105] Through the air curtain range hood introduced in this embodiment, the gas condition acquisition device can detec...

Embodiment 2

[0107] The difference between the air curtain range hood in this embodiment and the above embodiments is that: the working state of the impurity removal unit includes: different impurity removal ability levels of the impurity removal unit. When the gas condition acquisition device acquires that the content of oil fume reaches the threshold value corresponding to the different impurity removal ability levels, it adjusts its impurity removal ability to the impurity removal ability level corresponding to the threshold value.

[0108] Furthermore, in the curtain range hood introduced in this embodiment, the switch of the impurity removal unit controls the degree to which the impurity removal unit is connected to the air duct of the air curtain device. The impurity removal unit in this embodiment includes a multi-layer structure, and each layer can realize a certain impurity removal function. Preferably, the multi-layer impurity removal units have the same structure, and the number...

Embodiment 3

[0111] The difference between the air curtain range hood in this embodiment and the above embodiments is that the gas condition acquisition device includes an atmosphere acquisition switch unit for controlling whether the gas condition acquisition device is turned on.

[0112] Further, in the air curtain range hood in this embodiment, the atmosphere acquisition switch unit is connected to the air curtain device, and controls the working state of the air condition obtaining device according to the working state of the air curtain device.

[0113] Preferably, when the air curtain device is turned on / off, the atmosphere acquisition switch unit controls the gas condition acquisition device to be turned on / off and / or prompts for an acquired result and / or prompts for an operation suggestion.

[0114] Through the air curtain range hood introduced in this embodiment, a switch unit capable of controlling the working state of the gas condition acquisition device is added. Preferably, th...

Abstract

The invention discloses an air curtain range hood. The air curtain range hood comprises an air curtain device and a gas condition acquiring device, wherein the air curtain device is used for forming an air curtain and comprises an impurity removing unit for purifying gas in an air duct; and the gas condition acquiring device controls a working state of the impurity removing unit and/or prompts thegas condition of the air duct and/or prompts an operation suggestion according to the gas condition in the air duct of the air curtain range hood. According to the air curtain range hood, the turning-on condition of the impurity removing unit is improved, the impurity removing unit is turned on only when 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 ...
