Problems solved by technology

However, how to reasonably control the intensity of the air curtain airflow, so that the intensity of the air curtain airflow can be adapted to the current cooking environment, while forming an effective air curtain airflow, avoid excessively strong airflow, causing unnecessary power consumption and Noise becomes an urgent problem to be solved
Moreover, the air curtain device in the prior art requires the air curtain fan to provide air flow, which significantly increases the equipment noise and energy consumption of the equipment, and the separate control system for the air curtain device also increases the system burden and control burden of the equipment

Embodiment 1

[0214]When the air curtain angle-adjustable air curtain range hood described in this embodiment is working, the angle adjustment device respectively combines the data of the gas condition in the working area, the working state of the fan device and the current status of the air curtain device. The working status of the air curtain device is compared, and the air curtain angle of the air curtain device is adjusted according to the comparison result. The angle adjustment device implements pairwise evaluation on the various data obtained, and determines the adjustment method and adjustment range after the evaluation results are synthesized.

[0215] Further, the order of the air curtain angle-adjustable air curtain range hood introduced in this embodiment is judged according to the gas condition data in the working area prior to the judgment made according to the working state of the fan device. When implementing evaluation / judgment, the gas status in the work area is given prior...

Embodiment 2

[0217] The difference between the air curtain angle adjustable air curtain range hood introduced in this embodiment and the above embodiment is that the angle adjustment device determines whether to adjust the air curtain according to the data of the gas condition in the working area and the current working state of the air curtain device. The air condition judgment of adjusting the air curtain angle of the device; and adjust the air curtain angle of the air curtain device according to the result of the gas condition judgment and / or prompt the result of the judgment and / or prompt operation suggestions. Preferably, when the gas condition is determined to be yes, corresponding adjustments are made. When the gas condition judgment result is that the adjustment of the air curtain device should be implemented, the adjustment is implemented instead of continuing to judge the working state of the fan device. Mainly based on the actual use environment.

[0218] Further, in the air cu...

Embodiment 3

[0220] The difference between the air curtain angle-adjustable air curtain range hood introduced in this embodiment and the above-mentioned embodiments is that: when the result of the gas condition judgment is no, then according to the working state of the fan device and the air curtain device Judging the fan status according to the current working status; and adjusting the air curtain angle of the air curtain device according to the fan status judging result and / or prompting the judging result and / or prompting operation suggestions. When the result of fan state judgment is yes, make corresponding adjustments. When the result of the gas judgment is negative, the fan status is judged, fully considering the impact of the adjustment of the working state of the fan device on the cooking environment, and strictly limiting the diffusion of oil fume to the non-working area and the hidden danger of diffusion.

Abstract

The invention discloses an air curtain angle-adjustable air curtain range hood, comprising: an air curtain device for forming an air curtain; a fan device for providing power for the range hood to absorb oil fume; a gas condition acquisition device for Obtain the gas condition in the working area of ​​the range hood, and generate corresponding data on the gas condition in the working area; the angle adjustment device is connected to the air curtain device, and according to the data on the gas condition in the working area and the data of the fan device The working state adjusts the air curtain angle of the air curtain device and / or prompts the result of the judgment and / or prompts an operation suggestion. The air curtain angle adjustable air curtain range hood introduced in the present invention starts from multiple angles such as the working state of the range hood and the surrounding environment, comprehensively evaluates the air curtain angle of the air curtain device, and then adjusts it appropriately .

Description

technical field [0001] The invention belongs to the field of kitchen air purification equipment, and in particular relates to an air curtain angle-adjustable 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 ho...
