At present, most of the equipment is the range hood and the related improved equipment, and the types of the equipment are various, and the equipment has double cylinders, single cylinders, a cover type, upper air suction, lower air suction and the like. However, these range hoods are passive air suction devices, and the oil smoke suction port is a certain distance away from the cooking device that generates oil smoke, so that the oil smoke having certain kinetic energy and generated instantaneously during cooking cannot be completely removed. In order to solve the above problems, manufacturers of kitchen cleaning equipment often improve the range hood in a manner of changing the height and working power thereof, so that the fume suction effect is improved, but the problem of the fume overflowing from the periphery of the cooker still cannot be solved. In addition, the problem of oil smoke escape cannot be solved by increasing the area of the range hood cage to control the rising oil smoke below the smoke hood, increasing the power of the main motor and enhancing the smoke exhaust effect by large suction force. Therefore, how to effectively block the oil smoke from escaping becomes a problem which needs to be solved urgently. The performance requirements of consumers on kitchen air purification equipment are higher and higher, the large suction force becomes the pursuing target of various big merchants, but the problems of incomplete suction, oil smoke overflow and the like cannot be solved by the range hood sold on the market at present, a small part of range hood escapes from the front part of the machine in the cooking process, directly attacks clothes, hair and faces of cookers, is harmful to the skin of the faces, induces respiratory diseases if being sucked by human bodies for a long time, and directly influences the body health of the users. Therefore, the range hood in the prior art is provided with an air curtain device for solving the problem of oil smoke escape so as to isolate the user from the escaping oil smoke when the user uses the range hood. However, the air curtain device requires an air curtain fan to provide air flow, which significantly increases the noise and energy consumption of the device, and the separate arrangement of the control system for the air curtain device also increases the system load and control load of the device.
The present invention has been made in view of this situation.

After the technical scheme is adopted, compared with the prior art, the invention has the following beneficial effects.
1. The air curtain device is designed for opening conditions through the air curtain range hood introduced by the invention. A gas condition acquisition device is added on the range hood, and whether the air curtain device is started or not is controlled according to the detection result of the gas condition acquisition device. When the content of the oil smoke in the surrounding environment of the range hood reaches a certain degree, the air curtain device is automatically opened by the equipment, so that the oil smoke is prevented from invading users. Preferably, the gas condition acquiring device is arranged at one side of the equipment close to the user, and as the oil smoke harmful to the user is the part of the oil smoke diffused to the outside of the working area of the range hood, only the oil smoke outside the working area and in the operation range of the user is detected, whether the air curtain device is necessary to be opened or not can be accurately judged. The air curtain range hood introduced by the invention can also effectively prevent the air curtain device from being frequently opened, or further prevent the air flow of the air curtain device from influencing the oil smoke absorption of the range hood.
2. According to the air curtain range hood introduced by the invention, the plurality of gas condition acquisition devices are arranged and distributed, so that the condition that the detection result of a single detection device cannot fully represent the atmosphere environment around the range hood equipment can be avoided. After all, the atmosphere surrounding the range hood is a wider space relative to the working area of the range hood, and if the atmosphere within the range is detected, errors are easily caused by a single detection device.
3. According to the air curtain range hood introduced by the invention, the gas condition acquisition device is designed to be a multi-module matched design. During detection, the gas condition of the atmosphere environment around the range hood can be represented from multiple angles through representation of different atmosphere components such as oil smoke, water vapor and the like. Different thresholds are respectively designed for the oil smoke acquisition module and the moisture acquisition module. When the detection result of the oil smoke acquisition module reaches the corresponding oil smoke first threshold value, the air curtain device is controlled to be opened so as to prevent the oil smoke from invading the user. When the detection result of the moisture acquisition module reaches the corresponding first moisture threshold, the air curtain is controlled to be opened, the phenomenon that the sight of a user is shielded by water vapor is avoided, and the first moisture threshold is preferably larger than the first oil smoke threshold. The small amount of water vapor does not affect the user.
4. According to the air curtain range hood introduced by the invention, the detection results of the moisture acquisition module and the oil smoke acquisition module are integrated, and when the moisture acquisition module and the oil smoke acquisition module do not reach the corresponding first threshold value, the corresponding second threshold value is considered, wherein the first threshold value is larger than the corresponding second threshold value. And whether the air curtain device is necessary to be opened is judged according to the comprehensive condition of the moisture and the oil smoke.
5. According to the air curtain range hood introduced by the invention, the gas condition acquisition device is divided into two modules for detecting different substances. The boundary conditions for implementing the opening of the air curtain device/the opening of the impurity removal unit can be set to be different according to different atmosphere compositions. Preferably, the detection criteria for oil smoke should be stricter so that the value of the corresponding threshold for oil smoke is smaller than the corresponding threshold for water vapor, and the gas condition acquisition means is more sensitive to oil smoke than to water vapor.
6. The air curtain range hood introduced by the invention designs the control of the working condition of the impurity removal unit, and the impurity removal unit is adjusted to be in a working state only when necessary to play an impurity removal role. And when the atmosphere cleanliness does not reach the corresponding threshold, the impurity removal unit is not started. Because the edulcoration unit is arranged in going out the impurity in the air curtain air current, its setting can influence the validity of air curtain air current to a certain extent, and when this design can improve air curtain air current cleanliness factor, avoid influencing the effect of air curtain.
7. According to the air curtain range hood introduced by the invention, the impurity removal unit is connected with the atmosphere detection unit, and the working state of the impurity removal unit is controlled according to the detection result of the atmosphere detection unit, so that the function of self-adjustment of the equipment according to the use environment and the use condition is realized, the detection of the atmosphere detection unit is more accurate than the judgment of a user, and the timeliness of the implementation of the impurity removal function is ensured.
8. The air curtain extractor hood introduced by the invention improves the air flow source of the air curtain device, so that at least one part of the air discharged by the extractor hood is guided into the air curtain device to become the air flow source of the air curtain. The gas entering the air curtain device has kinetic energy instead of relying on the kinetic energy provided by the air curtain device, so that the energy required for forming air curtain airflow is obviously reduced, and the energy conservation and environmental protection are facilitated.
9. According to the air curtain range hood introduced by the invention, as the gas source of the air curtain airflow is the air around the kitchen range, the air is closer to the temperature around the kitchen range even if the air is transmitted through a longer path, and even if the air curtain with the temperature is directly contacted with a human body, a user does not feel discomfort caused by the temperature difference. Moreover, the temperature can obviously reduce the influence of the air curtain airflow on the food being cooked, and the food is prevented from being cooled.
10. According to the air curtain range hood introduced by the invention, the direction of the air inlet of the air curtain device is designed, so that the gas exhausted by the fan device can be more efficiently pushed into the air curtain device, and the phenomenon that the air curtain device stops the gas flow to cause the loss of the flowing performance of the gas flow is avoided.
11. The air curtain fume exhaust fan introduced by the invention designs the position of the air inlet of the air curtain device, the airflow performance of the position is most stable due to the maximum airflow kinetic energy of the position of the air outlet of the fan device, and the airflow of the position is fully purified under the condition that the purifying device is arranged in the fume exhaust fan, so that the fume contained in the fume exhaust fan is very limited, and the fume exhaust fan is more suitable for being used as the air curtain airflow.
