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

[0216] In the air curtain angle-adjustable air curtain range hood described in this embodiment, the angle adjustment device, after obtaining the working state of the fan device and the current working state of the air curtain device, judges whether the corresponding relationship between the two is within the corresponding threshold range, and adjust the air curtain angle of the air curtain device according to the result of the judgment and / or prompt the result of the judgment and / or prompt an operation suggestion. After the angle adjustment device obtains the current working state of the fan device and the air curtain device, it is judged whether the corresponding relationship between the two is within a reasonable threshold range, if yes, the working state of the air curtain device is not adjusted, if not, then according to the Adjust the working state of the air curtain device according to the judgment result and / or prompt the judgment result and / or prompt the operation sugge...

Embodiment 2

[0218] The difference between the air curtain angle-adjustable air curtain range hood in this embodiment and the above embodiment is that: the working state of the fan device is directly obtained from the control system of the range hood. This way of obtaining the working status is more direct and convenient. For example, the wind force of the fan device is generally controlled by the user directly through the control system of the fan device. When the user controls the fan device, the corresponding parameters for adjusting the working state of the fan device are transmitted to the range hood at the same time. The simultaneous control of the fan device and the air curtain device can be completed by implementing one adjustment. The control system of the fan unit includes the fan knob.

[0219] Furthermore, the working status of the fan unit of the range hood with adjustable air curtain angles included in this implementation includes: wind power gear and fan speed. Then the co...

Embodiment 3

[0221] The difference between the air curtain angle adjustable air curtain range hood described in this embodiment and the above embodiment is that: the air curtain angle adjustable air curtain angle range hood in this embodiment includes the air curtain air flow relative to the vertical The first-order angle in the vertical direction and / or the second-order angle of the angle coverage of the air curtain airflow at the air outlet of the air curtain device perpendicular to its moving direction. The angle of the air curtain is classified through the air curtain angle-adjustable air curtain range hood introduced in this embodiment. In one aspect, the air curtain angle includes the angle of the air curtain relative to vertical. Controlling the blowing direction of the air curtain can make the air curtain as close as possible to the source of oil fume, such as the mouth of the pot. This design can increase the distance between the oily fume and the user to a large extent, and is s...

Abstract

The invention discloses a cooker-linked air curtain range hood, which comprises an air curtain device for forming an air curtain and a fan device that provides power for the range hood to absorb oil fume, and adjusts the fan device according to the working state of the fan device. Describe the air curtain angle of the air curtain device and / or prompt the judging result of the air curtain angle and / or prompt the operation suggestion. The invention provides an air curtain angle adjustable air curtain range hood, which adds an angle adjustment device for controlling the air curtain device, and controls the air curtain device through the working state of the fan device within the working area of ​​the range hood The working state of the air curtain device has been reasonably controlled.

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...
