Detailed Description of the Drawings
-
The present invention focuses on an energy efficient mechanism for removing an exhaust air produced during burning of fuel, or cooking, however maintaining the air quality within the room where the burning of fuel and cooking is taking place. The invention uses the pressure change mechanism to reduce pressure within a paddle box through which the exhaust air is channelized because of pressure difference between inside of the paddle box, and out the paddle box where burning of fuel or cooking is taking place.
-
Fig 1 illustrates a schematic diagram of an arrangement 1 which enabled flowing of the exhaust air through the paddle box 2. The paddle box 2 is placed above a food cooktop 3 having burners 15. When the burners are on, and the food is being cooked onto the cooktop 3, steam is produced, which is one of the exhaust air required to be removed from a paddle box environment 7 in which the paddle box 2 is placed. It is to be noted that steam is produced generally when water is boiling, mostly in cases of making water based cooking, however, in cases where the oil based cooking is done, the exhaust air also includes air produced due to heating of oil. If the exhaust air is not pushed to outside of the room where the cooking is taking place, the exhaust air shall start expanding to remaining part of the room, and makes it uncomfortable for person in the room to breathe or stay. This exhaust air is required to channelize through a hollow structure 4 of the paddle box.
-
For channelizing the exhaust air, the arrangement 1 is provided with a pressure change mechanism 5. The pressure change mechanism 5 changes the inside pressure of an inside environment 6 inside the hollow structure 4 to be lower with respect to an environmental pressure of the paddle box environment 7. Such pressure change in the inside environment 6 pushed the exhaust air to expand toward the inside environment 6, and further makes a channel of air flow of exhaust air from the paddle box environment 7 to the inside environment 6. Once the exhaust air enters the inside environment 6, it further routed to outside of the room in which the paddle box 2 is placed.
-
The arrangement 1 is also provided with a sensor 9 which senses presence of the exhaust air and generates a presence data 10 related to presence of the exhaust air. The sensor 9 sends the presence data 10 to a controller, which processes the presence data 10, and based on the processing of the presence data 10, activates or deactivates the pressure change mechanism 5. Activation of the pressure change mechanism 5 enables it to create the pressure change by changing inside pressure. The pressure change is maintained by the pressure change mechanism 5 until the pressure change mechanism 5 is not deactivated. Once the pressure change mechanism 5 is deactivated, the inside pressure and the environment pressure starts getting into an equilibrium, and the channelizing of exhaust air is stopped. The controller 8 and the sensor 9, together provides a completely automated mechanism for functioning of the pressure change mechanism, where no human intervention is required. In an alternate embodiment, only the controller 8 is provided and the sensor 9 is not provided. In such scenario, human intervention is required to trigger the controller 8 for activation or deactivation of the pressure change mechanism 5. In yet another embodiment, even the controller 8 is not provided, and the user of the arrangement has to manually through any mechanical means activate or deactivate the pressure change mechanism 5.
-
Once the pressure change mechanism is activated, the sensor 9 further senses density of the exhaust air and generates a density data 11. The sensor 9 sends the density data 11 to the controller 8, and the controller 8 processes the density data 11, and based on processing, regulates the pressure change mechanism 5. In case that the density of the exhaust air within the inside environment 6 reduces, the controller 8 triggers the pressure change mechanism 5 to reduce the pressure difference between the inside environment 6 and the paddle box environment 7. This can be achieved by increasing the inside pressure. While, if the density of the exhaust air increases within the inside environment 6, the pressure change mechanism 5 increases the pressure difference between the inside environment 6 and the paddle box environment 7. This can be achieved by decreasing the inside pressure. In an alternate embodiment, the sensor 9 only generates the presence data 10, and need not generate the density data 11. In such case, the controller shall only activate or deactivate the pressure change mechanism 5.
-
The sensor 9 can be placed anywhere in the hollow structure 4, along any of the walls of the hollow structure or in proximity to the walls. This helps in generation of the presence data 10 or the density data 11 from within the inside environment. In another embodiment, the sensor 9 can be placed outside to the paddle box, either on paddle box, or in proximity to paddle box, or in proximity to the cook top 3, or any other location in the paddle box environment 7, so as to detect the presence or density of the exhaust air from the paddle box environment 7, despite of the inside environment 6, and accordingly the controller 8 activates, deactivates, or regulates the pressure change mechanism.
-
In one embodiment, the pressure change mechanism 5 can be based on cooling technique. The pressure change mechanism 5 works by changing an inside temperature of the inside environment 6 within the hollow structure to change the inside pressure
-
Implementation of the pressure change mechanism with cooling technique is illustrated in Fig. 2. This embodiment is shown with certain amendments from the embodiment of the Fig. 1, where the pressure change mechanism is shown to be comprising of a flow pipe 12, and a compressor 14. A part of the flow pipe 12 is arranged within the hollow structure 4. A cooling fluid flows through the flow pipe 12, and absorbs heat from the inside environment 6, which helps in reducing the inside temperature. Reduction of inside temperature reduces the inside pressure, and further creates required pressure difference between the inside pressure and the environmental pressure. The flow pipe 12 is arranged along one or more walls 13 of the hollow structure 4. Part of the flow pipe 12 can be within the hollow structure, and part of the flow pipe 12 can be outside. The flow pipe 12 is arranged along the walls 13 of the hollow structure 4 in a helical fashion. The flow pipe 12 can be arranged in any other geometrical fashion, like moving in vertically up-down fashion along the walls 13, or in a spiral shape inside the hollow structure 4, with part of the spiral touching the walls 13, and remaining part hanging within the hollow structure 4.
-
The flow pipe 12 is coupled to the compressor 14 which cools the cooling fluid before being flown into the part of the flow pipe 12 entering the hollow structure 4. The compressor 14 is placed outside the paddle box 2, hence part of the flow pipe 12 which is physically coupled to the compressor 14 is outside the hollow structure 4. In one embodiment, the compressor is not required, however, any cooling mechanism for cooling the cooling fluid can be used.
-
The controller 8 regulates the compressor 14 for activating, or deactivating the compressor 14, or varying the cooling of the cooling fluid flowing in the flow pipe 12, so as to regulate the inside temperature, or stop changing the inside temperature, as the case may be. The controller 8 activates or deactivates the compressor 14 based on the presence data 10 received from the sensor 9, and regulates the compressor 14 based on the density data 11. In one embodiment, the sensor 9 is not provided, and based on user intervention the controller 8 activates, deactivates, or regulates the compressor 14. In another embodiment, the controller 8 is not provided, and the user has to manually operate any mechanical means and activates, deactivates, or regulates the compressor 14.
-
Fig. 3 illustrates a method flow chart for regulating pressure change 5 between the inside environment and the paddle box environment using the arrangement of the Fig. 1. In step 101, the sensor is activated to detect the presence of the exhaust air and generate the presence data. In step 102, the controller processes the presence data and identifies if the exhaust air is present or not, and if the exhaust air is present the flow moves to step 103, otherwise the sensor keeps on checking the presence of exhaust air as per step 101. In step 103, the pressure change mechanism is activated by the controller, to change the inside pressure, so that the exhaust air can be channelized into the hollow structure of the paddle box. In step 104, the sensor starts checking the density of the exhaust air and generates the density data. In step 105, the controller receives and processes the density data, and checks if the density of the exhaust air has changed. If the density of the exhaust air has changes, the flow moves to step 106, otherwise the flow moves to step 104 to keep on generating the density data. In step 106, the controller receives and processes the density data, and based on processing regulates the pressure change mechanism to dependently increase the inside pressure. Once the pressure change has happened, the flow again moves to step 104 for generating the density data. In case the density of the exhaust air is identified to be nil or very less, which shall be the absence of the exhaust data, the controller shall deactivate the pressure change mechanism.
-
Thus, the present invention provides an arrangement 1 for flowing an exhaust air through a paddle box 2. When the paddle box 2 is placed above a fuel burner 3 and burns a fuel, or above a food cooktop 3 to cook food, such burning of fuel or cooking of food generates an exhaust air. The paddle box 2 includes a hollow structure 4 which channelize the exhaust air through itself. The arrangement includes a pressure change mechanism 5 which changes an inside pressure of an inside environment 6 inside the hollow structure to be lower with respect to an environmental pressure of a paddle box environment 7 surrounding the paddle box 2, such that the exhaust air is pushed through the hollow structure 4 of the paddle box due to a pressure difference between the environmental pressure and the inside pressure.
