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

[0243] In the smoke-stove linkage type air curtain range hood described in this embodiment, the flame state acquisition device acquires the flame state of the cooker every time the working state of the cooker changes, and generates historical flame data for evaluating the subsequent generation of flame data. other data. When generating historical flame data, the flame state acquisition device judges whether the current flame state can generate historical flame data according to the fluctuation and holding time of the flame state. The historical flame data is generated and recorded every time the working state of the cooker changes, and the historical flame data is used as comparison data in the subsequent evaluation process to judge whether the air curtain device affects the normal combustion of the flame of the cooker.

[0244] Further, in the technical solution in this embodiment, when generating historical flame data, the flame state acquisition device records the fluctuati...

Embodiment 2

[0247] The difference between the smoke-stove linkage type air-curtain range hood described in this embodiment and the above-mentioned embodiments is that the linkage device judges whether the current working state of the air-curtain device needs to be adjusted according to the working state of the cooker to determine the air-curtain state. , when the air curtain state judgment result is yes, adjust the working state of the air curtain device and / or prompt the judgment result and / or prompt operation suggestions. Whether to adjust the working state of the air curtain device is based on the working state of the cooker, and in terms of the degree of adjustment of the working state of the air curtain device, the flame state is used as the basis.

[0248] Further, in the range hood in this embodiment, when the air curtain state judgment result is yes, the linkage device predicts whether the adjustment of the working state of the air curtain device will affect the flame state accordi...

Embodiment 3

[0251] The difference between the smoke stove linkage type air curtain range hood described in this embodiment and the above embodiments is that after the working state of the air curtain device is adjusted, the linkage device is based on the current flame data and the current working state of the cooker. It is judged whether the adjustment is valid. When the flame data does not match the current working state of the cooktop, the adjustment is invalid; when the adjustment is invalid, the degree of adjustment to the working state of the air curtain device is reduced / increased. The technical solution in this embodiment determines whether the adjustment to the air curtain device is effective by comparing the target working state and the actual working state of the cooker. When the difference between the two is within the corresponding threshold range, the adjustment is valid, otherwise the adjustment is unnecessary.

Abstract

The invention discloses an air curtain range hood linked with a range hood, comprising: an air curtain device for forming an air curtain; a flame state acquiring device for acquiring the flame state of a cooker located within the working area of ​​the range hood to generate and record corresponding flame data; the linkage device is connected with the air curtain device and the cooker, adjusts the working state of the air curtain device according to the flame data and the working state of the cooker and / or prompts the The results of the above judgments and / or prompt operation suggestions. The invention provides an air curtain range hood linked with a range hood, in which a linkage device for controlling the air curtain device is added, and the working state of the air curtain device is controlled by the working state of the cooker within the range of the working area of ​​the range hood , implemented a reasonable control of the working state of the air curtain device.

Description

technical field [0001] The invention belongs to the field of kitchen air purification equipment, and in particular relates to a smoke stove linkage type air curtain range hood. Background technique [0002] The kitchen purification equipment in the prior art mostly relies on air flow to improve the gas environment in the kitchen. At present, most of this type of equipment are range hoods and related improved equipment. There are various types of models, such as double-cylinder, single-cylinder, hood type, upper suction, and lower suction. However, these range hoods are passive air suction devices, and their range hoods are at a certain distance from the cooker that produces the range hoods, so the range hoods that are instantaneously generated during cooking and have a certain kinetic energy cannot be completely eliminated. In order to solve the above problems, the manufacturers of kitchen purification equipment have mostly improved by changing the height and working power ...
