Definitions

  • the present disclosure relates to a cookstove. More particularly, the present disclosure relates to an improved forced draft cookstove.
  • This draught system is known as positive draught system or forced draught system because the pressure and air is forced to flow through the system.
  • the natural draught created by primary air source is very less, due to this the fuel under combustion chamber is not burnt properly and combustion does not take place properly which results less efficiency of the stove and wastage of fuel.
  • the air holes provided on the combustion chamber are not variable and same in sizes which restrict the combustion process by not efficiently burning of fuel and also reduces the overall heat generating capacity of the cookstove. In some cookstoves only natural draft method of air is used and no holes or jacket arrangement is made which reduces the overall efficiency of the cookstove.
  • the smoke generated by burning of the fuel is hazardous to health of the user nearby.
  • no flaps are used to cover the fuel feeding section of the cookstove which makes the smoke due to burning of fuel to come out of the cookstove and adversely affect the user or people standing near the cookstove.
  • the exhaust gas or smoke helps in maintaining the burning temperature of the fuel and the dismissal of this smoke directly outside while burning creates burning eye and lungs issues if used for a prolonged period of time.
  • a tray is used to place the fuel such as wooden chips of a particular size for burning as the tray is not having an adjustment to allow sizes of different wood to be placed.
  • Another obj ect of the present invention to provide a forced draft cookstove with a kind of combustion chamber for better overall combustion.
  • Yet another object of the present invention to provide a forced draft cookstove with cleaner combustion and reduced heat loss.
  • One more object of the present invention to provide a cookstove with better thermal insulation and usability.
  • a forced draft cookstove with improved efficiency.
  • the cookstove includes a squared shaped base on which a housing is arranged.
  • a handle is peripherally arranged on the housing for ensuring safe handling of the cookstove.
  • a combustion chamber is arranged inside the housing having a cap arranged on a top portion of the combustion chamber and the cap having a central opening to facilitate proper airflow and ventilation.
  • the combustion chamber and the cap are made of heat resistant material to withstand high temperatures during the combustion process.
  • a vessel setter is arranged above the cap to support cooking vessels along with a fuel feeding section at bottom portion of the housing for facilitating fuel feeding and ash removal.

  • a front flap is pivotally arranged on a portion of the fuel feeding section which prevents the smoke to come out.
  • a blower which is operatively coupled with a motor for supplying air to the combustion chamber and the blower is adjustable in speed or intensity to regulate the combustion process.
  • the front flap is having a dual flap arrangement made of heat resistant material to withstand the high temperature during combustion.
  • a casing is attached on the periphery of the housing inside a case, the casing includes a rechargeable battery which powers the motor allowing blower to supply air to the combustion chamber through an air cap arranged at a bottom portion of the housing.
  • the air cap is an air distribution channel having an ingress and an egress channel to allow the supply of air from the blower to a narrow air passage arranged width wise the combustion chamber along with the air jackets arranged on the top portion of the combustion chamber.
  • the casing is having a magnetic arrangement for attachment and detachment on the periphery of the housing.
  • the casing further comprises a charging port for external power input to recharge the rechargeable battery along with a power switch to operate the blower.
  • an insulation support surrounding the combustion chamber is also arranged for configuring a filter chamber therebetween to absorb the smoke released while burning fuel in the combustion chamber.
  • a plurality of air jackets are radially and circumferentially arranged around a top portion of the combustion chamber wherein the air jackets have an alternating diameter followed by periodic repetition and the air jackets are aligned in a same radial plane.
  • the air jackets are small holes having alternating diameter which lies on a single radial plane perpendicular to the central axis of the combustion chamber and the air jackets are of different and predesigned sizes to allow better air flow and efficient overall combustion.
  • an anti-slip legs arrangement is adapted below the squared shaped base at end points to enable a sturdy grip. The cookstove provides a forced draft method of supplying air to the combustion chamber which ensures improved efficiency and usability.
  • the forced draft cookstove (100) comprising a housing (110), a combustion chamber (180), a tray (210), and a casing (130).
  • the housing (110) encloses all the stove components and serves multiple purposes, including containing the heat generated during combustion, providing insulation, and directing the airflow for efficient operation.
  • the housing (110) is provided with a squared shaped base (120) for better stability.
  • a handle (160) is peripherally arranged on the housing (110) for ensuring safe handling of the cookstove (100).
  • the handle (160) of the forced draft cookstove (100) extends from the top portion of the housing (110) surrounding the cookstove (100).
  • the handle (160) is designed to provide a convenient grip for users to hold and carry the stove (100).
  • the handle (160) extends outward from the housing (110), creating a protrusion that can be easily grasped by the user's hand. This extension allows for a secure grip and provides stability while lifting or moving the cookstove (100).
  • the embodiment includes openings on opposite sides of the handle's (160) extension. These openings serve as spaces for the user's fingers to grip the handle (160) firmly. By placing fingers through these openings, users can achieve a comfortable and secure hold on the cookstove (100) while lifting or transporting it.
  • a vessel setter (170) is arranged above the top cap (190) to support cooking vessels.
  • the vessel setter (170) is a metal frame that is placed above the top cap (190) of the stove (100) to support cooking vessels such as pots and pans.
  • the cook stove (100) also includes a fuel feeding c type section (220) which is arranged at bottom portion of the housing (110) for facilitating fuel feeding and ash removal.
  • the fuel feeding C type section (220) is arranged at the bottom portion of the housing (110) of the forced draft cook stove (100) which is designed to facilitate fuel feeding and ash removal.
  • a safety cover (280) is also used to cover the front c type fuel feeding section (220).
  • the casing (130) includes a charging port (150) for external power input to recharge the rechargeable battery along with a power switch (141) to operate the blower (140).
  • the power switch (141) can be turned ON or OFF depending on the requirement of the user.
  • the air is circulated into the combustion chamber (180).
  • an air cap (230) is arranged at the bottom portion of the housing (110) to receive air from the blower (140) and to circulate or supply towards the combustion chamber (180) (as shown in figure 2).
