Problems solved by technology

But in actual use, the working environment faced by range hoods is more complicated, especially in the environment with multiple burners, such as the kitchen of a restaurant, where the range hood is located in a larger space, the phenomenon of oil fume diffusion is more obvious, and multiple burners According to the different usage conditions, there are different levels of oil fume flowing in different work areas, which increases the difficulty of oil fume shielding

Embodiment 1

[0076] Wind screen hood embodiment of the present embodiment, the status acquisition means acquires the gas status in different positions of the gas around the hood and controls the operating state of the wind receiving unit based on the gas conditions. Since the air cell volume is small, flexible installation position, a plurality of positions of the hood may be provided on, even if relatively narrow space. For more complex the atmosphere, according to the composition and content of soot, the control unit of the wind turn-on timing, the open air only when the unit needs to be shielded position fumes. The operating status of the air unit comprises: on, off, and / or the air volume adjusting and / or wind direction adjustment.

[0077] Further, when the gas status acquisition gas condition means acquires a gas condition of the respective value range hood in the present embodiment exceeds the corresponding threshold, the control corresponding to the air unit is turned on, and / or t...

Embodiment 2

[0080] Wind screen hood of the present embodiment is described in the above-described embodiment except that: the at least two adjacent said air outlet means constitutes a outlet, the outlet is an outlet air curtain, a continuous structure, of the outlet the number is at least two. Preferably, said detecting comprising acquiring manner. Obtaining data can also be obtained through other devices within the work environment. A plurality of air outlet unit may be connected integrally, constituting a range of a complete wind outlet. When the outlet air curtain generating a whole, continuous air curtain.

[0081] Further, the number of the gas condition acquiring apparatus according to the present embodiment is a plurality of embodiments, a plurality of the gas condition data acquisition means acquires a different position, the plurality of status acquisition means and said gas outlet disposed one correspondence. Then, each corresponding to a gas outlet status acquisition means when a c...

Embodiment 3

[0083] Wind screen hood of the present embodiment is described in the above-described embodiment except that: the gas condition for each condition acquisition means acquires different gas components. The gas comprises status acquisition means for acquiring fume hood content acquisition module and / or water for obtaining a moisture content acquisition module. Treated separately for different components forming fumes, set different thresholds for different components. When the data exceeds the corresponding threshold fume hood obtaining module, the acquisition module corresponding to open the hood air curtain device. When soot obtaining module data does not exceed the corresponding threshold soot, moisture and then further determines whether the acquisition module acquiring a value greater than a threshold value corresponding to fumes. Preferably, the moisture fumes threshold ≥ threshold. Evaluation of the fume hood more demanding, and the evaluation of the moisture more relaxed, t...

Abstract

The invention discloses an air curtain range hood, comprising: an air curtain device for forming an air curtain, including at least two air outlet units with different positions and capable of independently adjusting the working state; a gas condition acquisition device through which The gas condition in the surrounding environment of the air curtain range hood controls the working state of the air curtain device and / or prompts the gas condition in the surrounding environment and / or prompts for operation suggestions. The air curtain range hood introduced in the present invention designs the generation position of the air curtain so that the air outlets are arranged along multiple positions of the range hood, and the air outlets at different positions adjust their working states according to their corresponding environmental conditions, which is targeted Effectively shield the fume generated in different areas.

Description

Technical field [0001] The present invention is in the field of kitchen air purification apparatus, and more particularly, to a wind screen hood. Background technique [0002] The prior art devices rely more purification kitchen air flow to improve the kitchen atmosphere. Currently, such devices are mostly related hood and improved apparatus, a variety of model types, there is binocular, monocular, hood, the suction, the suction and the like. However, these are passive hood air suction apparatus smoke fumes from the cooking fumes opening a certain distance, so the cooking generated at the moment, with a certain kinetic energy can not be completely excluded fumes. In order to solve these problems, various kitchen multi-purification equipment manufacturers from changing the height of the hood, the power of working to improve the way that the effect of smoke fumes has improved, but still can not solve the problem of fumes escaping from the surrounding cookware. Further, the fumes es...
