BACKGROUND ART

Generally, when a user cooks in a kitchen, the user is required to manually control the operation state of other kitchen appliances, viz a chimney / hood and the automation degree is low. The existing range hood generally comprises a machine body, a smoke collecting hood and a wind cabinet assembly; the smoke collecting hood and is connected with the bottom of the machine body and used for sucking oil smoke, the air cabinet assembly is located in the machine body and used for sucking the smoke collecting hood into the oil smoke exhausting machine body in the machine body and exhausting the oil smoke into a flue.

At present, smart range hood on the market can realize the interconnection function between the range hood and a cooker or can use a mobile phone to control the fan of the range hood. Many prior art literature aims to solve technical problem of providing an control method of a range hood based on multiple sensors.. The control method of the range hood can automatically and intelligently adjust the fan according to the oil smoke environment condition in the kitchen environment, and improves the oil smoke absorption effect. However, in the face of a complex oil smoke environment in a kitchen environment where the range hood is located, the existing intelligent range hood cannot accurately identify the oil smoke environment in the kitchen, and further, the output gear of the fan cannot be adjusted more accurately and automatically, so that the range hood is poor in oil smoke absorption effect in the kitchen.

Therefore, the current technology chimney teaches auto ON feature based on Temperature sensor/smoke sensor & Motion Sensor. Due the variety of fumes, temperature and its concertation time Chimney gets delayed its operation on needed time. In this case entire kitchen gets spilled with smokes which will deteriorate the consumer health condition if any child/aged person, the severity will be more based on their health.

Problems with conventional technology is mentioned as under:

Fume/Smoke sensor:

With respect to difference in food preparation methods & ingredients use lead to different fume properties. The available smoke sensor has the restriction to detect the different type of gases due to the changes in its density, oily, airborne content, etc. Over period this air borne, and oily gases blocks the sensor which will deteriorate its function of sensing capacity. And the location of fume senor to detect the fume, timing required to sense detect is another detection issue.

Temperature sensor:

Problem with temperature sensor need certain time to reach the specific temperature to Turn ON the product irrespective of this position sensor to detect. Meanwhile the entire room ruins with fumes and airborne, etc. along with the room temperature increase. Consumer also must bear the smoke and airborne till the appliance sucks.

Over period this air borne, and oily gases blocks the temperature sensor which will deteriorate its function of sensing capacity. And the location of temperature senor to detect the fume temperature which is time consuming process in detection.

Motion Sensor:

User must give input to the Hood to turn ON/OFF. Multi-times of activation to be given by the consumer both product in separate for Cook top as well as chimney.

DETAILED DESCRIPTION

The technical scheme adopted by the invention for solving the above-mentioned complex technical problems is as follows: the intelligent control system of the chimney / hood and hob based on single / mono switching. As it is shown in figure 1, the present embodiment relates to a kind of intelligent intelligent control system for HOOD which controls the switching of hood while cooking simultaneously.

As shown in figure 1, the hood used for domestic/commercial Cooking, mainly comprising of- Blower, Blower Housing, Main housing, Filter, LED and Sensor. The range hood also includes casing and is installed on this Blower fan apparatus in casing, blower fan apparatus realizes work under the driving of an intelligent control system.

While operating the cooker hood, temperature rises sometimes due to smokes and high temperature flame. Smokes may have cause of suffocation and can be dangerous and harmful to peoples and children. This sensor detects automatically temperature difference from ambient temperature and cooker hood automatically start at full speed. Kitchen temperature are the number one source of residential home temperature rise, and unattended cooking is the leading cause of kitchen temperature rise. Kitchen temperature rise risk is seen by users as a major problem. The present cooker hoods have smoke sensor or infrared sensor which detects fumes and temperature rise in cooker hood, and cooker hood starts running at a set temperature rise and high amount of smokes.

It is a technology for throw harmful gases out of the kitchen and save from suffocation.

• In this function we are using heat sensor technology in cooker hood for start smart auto-on.
• When the hood temperature is increasing 5°C from ambient temperature heat sensor detect temperature rise and start cooker hood with high speed.
• When cooking starts, fumes are produced. These fumes and high heat detected by the sensor through temperature difference and signal is sent to the control panel of Hood and it gets automatic switched on.

Control unit programmed to activate the chimney in time delay with rise in temperature above 5 Deg Cel. After fire with certain time delay chimney will TURN ON automatically. The Motor will start working when fume’s get generated in kitchen while cooking as shown in Fig 3.

The intelligent degree of this scheme is high, can effectively reduce user's operation, and improves user's use and experiences. Moreover, in an embodiment, the rotating speed may be adjusted according to the smoke concentration, so that compared with manual adjustment of a user, the situation that the air volume is small when the amount of oil smoke is large does not occur, and the situation that the air volume is large when the amount of oil smoke is small does not occur; the oil fume suction effect is better, and the energy is more saved.

In another exemplary embodiment, the said intelligent control system can be connected with other equipment to form an internet of things, so that the smoke concentration value and the operation data are collected, a hood database is conveniently established subsequently, and data support is provided for subsequent data analysis based on the large database.
