Embodiment 1

[0104] In the air curtain range hood described in this embodiment, the working state of the impurity removal unit includes: open and / or closed states, and when the gas condition acquisition device obtains the presence / absence of oil smoke, the impurity removal unit is controlled Units turn on / off and / or prompt for acquired results and / or prompt for action suggestions. The technical solution in this embodiment defines conditions for the switching of the working state of the impurity removal unit. When the impurity removal unit is in working condition, it may increase the control burden of the system or increase the airflow resistance in the air curtain duct. Then, when the gas condition cannot meet the opening condition of the impurity removal unit, the impurity removal unit is turned off. The means for the device to obtain the gas condition include detection, or input by the user. The input item can be determined by the user's subjective feeling, such as serious, slight, and ...

Embodiment 2

[0107] The difference between the air curtain range hood described in this embodiment and the above embodiment is that the impurity removal unit is a deflectable sheet structure arranged in the air duct of the air curtain device. When the impurity removal unit is turned on, the impurity removal unit The lamellar structure is turned over at an angle to the direction of air flow. When the impurity removal unit is turned off, the lamellar structure is turned over to be parallel to the airflow direction.

[0108] Furthermore, 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 of layers of the impurity removal units connected to the air duct of the air curtain device can be controlled by the switch of the impurity removal units. When the multi-layer impurity removal unit is connected to the air duct, ...

Embodiment 3

[0111] The difference between the air curtain range hood described in this embodiment and the above embodiment is that: the gas condition acquisition device includes an atmosphere acquisition switch unit for controlling whether the gas condition acquisition device is turned on; the atmosphere acquisition switch unit is connected to The air curtain device is connected, and controls the working state of the gas condition acquisition device according to the working state of the air curtain device. 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.

[0112] In this embodiment, a switch unit capable of controlling the working state of the gas condition acquisition device is added. Preferably, the switch unit is connected to the air curtain device. When the air curtain device is working, the switch unit ...

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 includesan impurity removal unit for purifying gas in an air duct of the air curtain of the air curtain device, 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 impurity removal unit 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 curtain range hood, air curtain airflow generated by the air curtain device is subjected to impurity removal, the quality of the air curtain airflow is ensured, 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 ...
