A stove device for controlling flue gas source and coordinating water vapor recovery

Abstract

This invention relates to the field of stove equipment technology, and discloses a stove equipment with flue gas source control and coordinated water vapor recovery. The invention, through a control mechanism, firstly activates the solenoid valve and the first fan via a controller, initiating combustion upon ignition. Simultaneously, a carbon monoxide sensor detects the carbon monoxide content inside the top outer shell, automatically adjusting the fuel-air ratio to prevent incomplete combustion and thus avoid excessive carbon particle production during combustion. Secondly, through a moisture absorption mechanism, a second fan is activated, drawing water vapor through a fixed plate and introducing it into the condensation chamber. This allows the flue gas and water vapor to mix, causing particulate matter and mist droplets in the flue gas to collide and combine, resulting in particle agglomeration and sedimentation. This significantly reduces the pollution of the flue gas to the environment and the harm to users.

Description

Technical Field

[0001] This invention relates to the field of stove equipment technology, specifically a stove equipment that controls flue gas source and coordinates water vapor recovery. Background Technology

[0002] The term "stove" refers to heating equipment used for cooking. It is divided into two categories: fixed and portable. Fixed stoves include earthen stoves and brick stoves. The stove body consists of a stove door, stove chamber, stove platform, stove holes, and chimney. They are mostly fueled by firewood and are the main stoves for cooking in rural homes. Portable stoves are smaller and are mostly made of pottery or metal.

[0003] For example, Chinese patent application number 201720518349.3 allows for adjustment of combustion temperature as needed, improving ease of use. However, the practical performance of this stove is poor. It cannot automatically adjust the fuel-air ratio during combustion, making it difficult for the fuel to burn completely. This results in excessive particulate matter being produced during combustion, which greatly affects the health of users. At the same time, the functionality of existing stoves is poor. They cannot extract and treat the generated water vapor, which easily escapes into the room, greatly affecting the user's field of vision and reducing thermal comfort. It has certain limitations.

[0004] Therefore, how to design a stove equipment that controls flue gas source and recovers water vapor has become a problem that needs to be solved. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stove device with flue gas source control and coordinated water vapor recovery, which solves the problems of poor practical performance of existing stove devices, their inability to automatically adjust the fuel-air ratio during combustion, and their poor functionality, as they are unable to extract and process the generated water vapor.

[0006] The technical solution of this invention:

[0007] A stove device with flue gas source control and coordinated water vapor recovery includes a bottom outer shell 1, a top outer shell 10, an automatic igniter 19, a control mechanism, and a moisture absorption mechanism. The control mechanism includes a controller 2, a flow sensor 3, a solenoid valve 4, a chimney 5, an air duct 6, a primary fan 7, a carbon monoxide sensor 8, and a touch screen 9. The moisture absorption mechanism includes a fixing plate 11, a secondary fan 12, a condensation box 13, a threaded section 14, a porous mesh 15, and an adsorption coating 16. The top outer shell 10 is installed on the upper surface of the bottom outer shell 1, and through holes are provided at corresponding positions on the upper surface of the bottom outer shell 1 and the lower surface of the top outer shell 10 for the air duct 6 to pass through.

[0008] The touch screen 9 is located on the front of the bottom housing 1. The controller 2, flow sensor 3, solenoid valve 4, and air duct 6 are located inside the bottom housing 1. The bottom housing 1 has a through hole on its side. One end of the air duct 6 passes through the through hole on the side of the bottom housing 1 and extends to the outside of the bottom housing 1. The first fan 7 is located outside the bottom housing 1 and connected to the end of the air duct 6. The solenoid valve 4 and flow sensor 3 are both located on the air duct 6. The controller 2 is electrically connected to the touch screen 9, solenoid valve 4, flow sensor 3, first fan 7, and carbon monoxide sensor 8. The controller 2 controls the opening and closing of the solenoid valve 4 and the first fan 7 and collects signals from the flow sensor 3 and the carbon monoxide sensor 8. The top housing 10 has a through hole on its side for installing a chimney 5. The top of the chimney 5 leads to the outside. The other end of the air duct 6 passes through the through holes on the upper surface of the bottom housing 1 and the lower surface of the top housing 10 in sequence and extends into the interior of the top housing 10. The carbon monoxide sensor 8 is installed at the bottom inside the top housing 10 and is located next to the air duct 6.

[0009] The automatic igniter 19 is connected to the controller 2 and installed at the bottom of the top housing 10; the upper surface of the top housing 10 has a through hole at the center for installing the cookware 17.

[0010] The fixing plate 11 is vertically installed on the upper surface of the top outer shell 10 and located on the side of the cooker 17. The fixing plate 11 is provided with multiple sets of ventilation holes. The second fan 12 and the condensation box 13 are both installed on the side of the top outer shell 10, with the second fan 12 located above the condensation box 13. The second fan 12 is connected to the inside of the condensation box 13. The second fan 12 draws in the internal air from the outside of the fixing plate 11 through the through holes, creating a negative pressure inside. The negative pressure environment inside the fixing plate 11 then draws in the water vapor leaking from the cooker 17 and delivers the drawn water vapor to the condensation box 13. The condensation box 13 has openings on both its front and rear faces. The rear face opening is directly connected to another through hole on the side of the top outer shell 10, allowing the condensation box 13 to communicate with the top outer shell 10. A porous mesh 15 is installed on the front face opening, and the inner wall of the porous mesh is coated with an adsorption coating 16. Fuel is delivered to the top outer shell 10 through the front and rear openings of the condensation box 13.

[0011] Preferably, an observation window 18 is fixedly connected to the front of the condensation box 13, and the observation window 18 is colorless and transparent.

[0012] Preferably, the inner wall of the front end face of the condensation box 13 is provided with a threaded section 14, and the periphery of the porous mesh 15 is provided with threads that mesh with the threaded section 14.

[0013] The beneficial effects of this invention are:

[0014] (1) By setting up a control mechanism, the present invention can first open the electromagnetic valve and the No. 1 fan through the controller, and then ignite to start combustion. At the same time, the carbon monoxide sensor is used to detect the carbon monoxide content inside the top shell. If carbon monoxide is generated, the power of the No. 1 fan can be increased through the controller, thereby drawing more air into the interior of the top shell, which can automatically adjust the fuel-air ratio, avoid incomplete combustion of fuel, and thus avoid generating too many carbon particles during combustion.

[0015] (2) By setting up a moisture absorption mechanism, the present invention can first start the No. 2 fan, draw water vapor through the fixed plate, and pass the water vapor into the interior of the condensation box, so that the flue gas and water vapor mix together, and the particulate matter in the flue gas collides and combines with the mist droplets, causing the particulate matter to condense and settle, which can greatly remove the particulate matter in the flue gas by settling, greatly reducing the pollution of the flue gas to the environment and the harm to users.

Detailed Implementation

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and technical solutions.

[0022] like Figure 1-4As shown, a stove device for flue gas source control and coordinated water vapor recovery according to the present invention includes a bottom outer shell 1, a controller 2, and a top outer shell 10. The controller 2 is fixedly connected to the left side of the interior of the bottom outer shell 1. A flow sensor 3 is connected to the right side of the controller 2. A solenoid valve 4 is connected to the bottom right side of the flow sensor 3. An air pipe 6 is penetratingly connected to the inner wall of the solenoid valve 4. A fan 7 is connected to the right side of the air pipe 6. A carbon monoxide sensor 8 is connected to the top right side of the air pipe 6. A touch screen 9 is fixedly connected to the front of the bottom outer shell 1. The top of the bottom outer shell 1 is fixedly connected to... A top outer shell 10 is fixedly connected. A through hole is provided on the right side of the top outer shell 10 for connecting a chimney 5. A fixing plate 11 is fixedly connected to the top left side of the top outer shell 10. A second fan 12 is connected to the bottom left side of the fixing plate 11. A condensation box 13 is connected to the bottom of the second fan 12. A threaded section 14 is provided on the left side of the inner wall of the condensation box 13. A perforated mesh 15 is connected to the inner wall of the threaded section 14. An adsorption coating 16 is applied to the inner wall of the perforated mesh 15. A cooker 17 is connected to the top middle part of the top outer shell 10. An automatic igniter 19 is connected to the left side of the air pipe 6.

[0023] Preferably, an observation window 18 is provided in front of the condensation box 13. The front view of the observation window 18 is rectangular and is colorless and transparent. Existing stoves cannot observe the amount of dust inside and cannot clean it in time. Since the observation window 18 is colorless and transparent, the user can observe the dust inside the condensation box 13 through the observation window 18, which makes it easier for the user to clean the dust inside the condensation box 13 in time and improves the practicality of the device.

[0024] Preferably, the left side of the chimney 5 extends through the top outer casing 10, and its top opens to the outside. The controller 2, the first fan 7, and the carbon monoxide sensor 8 are electrically connected. The control mechanism consists of the controller 2, the flow sensor 3, the solenoid valve 4, the chimney 5, the air duct 6, the first fan 7, the carbon monoxide sensor 8, and the touch screen 9. Existing stove equipment has poor practical performance; it cannot automatically adjust the fuel-air ratio during combustion, making it difficult for the fuel to burn completely, thus resulting in excessive particulate matter during combustion. This invention, through the establishment of a control mechanism, firstly unscrews the porous mesh 15 and places fuel inside the top outer shell 10, then reinstalls the porous mesh 15. The controller 2 opens the solenoid valve 4 and simultaneously activates the first blower 7 to draw air into the top outer shell 10. Then, the automatic igniter 19 is activated to ignite the fuel. Simultaneously, a carbon monoxide sensor 8 detects the carbon monoxide content inside the top outer shell 10. If carbon monoxide is generated, the controller 2 increases the power of the first blower 7, thereby drawing more air into the top outer shell 10, automatically adjusting the fuel-air ratio to prevent incomplete combustion. Simultaneously, a flow sensor 3 monitors the airflow, effectively controlling the amount of air entering the system. The touchscreen 9 provides real-time feedback of the monitoring data, and the chimney 5 vents the flue gas outwards. This mechanism automatically adjusts the fuel-air ratio during combustion, allowing for better combustion and preventing excessive particulate matter production, thus improving the device's practicality.

[0025] Preferably, the fixed plate 11 has five sets of ventilation holes on the right side, with six ventilation holes in each set. The periphery of the porous mesh 15 is threaded, and this thread can engage with the threaded section 14. The moisture absorption mechanism consists of the top outer shell 10, the fixed plate 11, the second fan 12, the condensation box 13, the threaded section 14, the porous mesh 15, and the adsorption coating 16. Existing stove equipment has poor functionality and cannot effectively extract and process the generated water vapor, allowing it to easily escape into the room, which greatly affects the user's field of vision and thermal comfort. This invention, by setting up a moisture-absorbing mechanism, first activates the second fan 12, thereby drawing air from inside the fixed plate 11 to create a negative pressure. This negative pressure environment then draws in water vapor leaking from the cookware 17 and directs the water vapor into the condensation chamber 13, creating a supersaturated vapor chamber. Simultaneously, the combustion flue gas can be directly introduced into the condensation chamber 13, allowing the flue gas and water vapor to mix. When the dust-laden flue gas enters the supersaturated vapor chamber, the particulate matter and mist droplets collide and combine, causing the particles to condense and settle. This significantly reduces the particulate matter in the flue gas. After sedimentation and removal, the flue gas is passed through the porous mesh 15. Due to the good adsorption capacity of the adsorption coating 16, particulate matter can be adsorbed and removed through the adsorption coating 16 on the outer wall of the porous mesh 15, thereby preventing flue gas from entering the room through the packing port. At the same time, the porous mesh 15 and the condensation box 13 are connected by a threaded section 14, which is extremely simple and allows for quick disassembly and replacement of the porous mesh 15, making it convenient to use. This mechanism can not only remove water vapor, but also accelerate the sedimentation and adsorption removal of particulate matter in the flue gas, greatly reducing the pollution of the environment and the harm to users caused by the flue gas, and improving the practicality of the device.

[0026] In summary, the workflow of this invention is as follows: First, the controller 2 opens the solenoid valve 4 and the first fan 7, and combustion begins upon ignition. Simultaneously, the carbon monoxide sensor 8 detects the carbon monoxide content inside the top outer shell 10. If carbon monoxide is generated, the controller 2 increases the power of the first fan 7, thereby drawing more air into the top outer shell 10. This automatically adjusts the fuel-air ratio, preventing incomplete combustion of the fuel. The second fan 12 can then be activated, drawing water vapor through the fixing plate 11 and introducing it into the condensation chamber 13. This allows the flue gas and water vapor to mix, causing particulate matter and mist droplets in the flue gas to collide and combine, resulting in particle agglomeration and sedimentation. This process greatly reduces and removes particulate matter from the flue gas. The observation window 18 is colorless and transparent, allowing the user to observe the dust accumulation inside the condensation chamber 13.
