Embodiment 1

[0097] In the air curtain range hood described in this embodiment, the impurity removal capability judging device adjusts the working state of the air curtain range hood and / or prompts the judgment result of the working state of the air curtain range hood according to the result of the judgment and / or suggest action.

[0098] According to the air curtain range hood introduced in this embodiment, when the impurity removal device shows insufficient impurity removal capacity, it may be that the impurity removal device needs to be replaced and cleaned, or at this time, the oil fume near the stove is heavy. At this time, adjust the fan device of the equipment to increase the suction capacity. The present invention further introduces an impurity removal device / unit with adjustable impurity removal capacity. Combining with the impurity removal device / impurity removal unit introduced in the present invention, the air curtain range hood can be obtained through the gas condition acquisi...

Embodiment 2

[0101] The difference between the air curtain range hood in this embodiment and the above embodiment is that the air curtain range hood includes a fan device for generating air flow, and the air duct includes a fan duct of the fan device.

[0102] Further, the air duct gas status acquisition device in this embodiment includes an air curtain duct gas status acquisition device for acquiring the composition / content of gas components in the air curtain duct. The air channel gas condition acquisition device includes a first air channel gas condition acquisition device for acquiring the side of the airflow in the air curtain air channel moving toward the impurity removal unit. The impurity removal ability judging device compares the data obtained by the first air duct gas condition acquisition device with the data acquired by the work area gas condition acquisition device, and when the result of the comparison between the two does not exceed a threshold value, the impurity removal T...

Embodiment 3

[0104] The difference between the air curtain range hood described in this embodiment and the above embodiment is that: the air duct gas condition acquisition device includes an air curtain air duct gas condition for acquiring the gas composition / content in the air curtain air duct Acquisition means: the air duct gas condition acquisition means includes a second air duct gas condition acquisition means for acquiring the side of the wind curtain air duct where the airflow moves away from the impurity removal unit.

[0105] Further, the impurity removal capability judging device in this embodiment compares the data obtained by the second duct gas condition acquisition device with the data obtained by the work area gas condition acquisition device, and when the result of the comparison between the two does not exceed the threshold , then the impurity removal device and / or the impurity removal unit has good impurity removal ability.

[0106] In the air channel of the air curtain d...

Abstract

The invention discloses an air curtain extractor hood. The air curtain extractor hood comprises an air curtain device, an impurity removing device, a gas condition acquisition device and an impurity removing capability judgment device, wherein the air curtain device is used for forming an air curtain, the impurity removing device is used for removing impurities in an air flue of the air curtain extractor hood and comprises an impurity removing unit arranged in the air curtain device, the gas condition acquisition device is used for acquiring the gas condition, and the impurity removing capability judgment device judges the impurity removing capability of the impurity removing device through data obtained by the gas condition acquisition device. According to the air curtain extractor hood,air flows in the air flue of the extractor hood are subjected to impurity removing, and the impurity removing condition in the air flue is monitored so as to control the cleanliness of the air flows.

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 ...
