Bhopal,Madhya Pradesh, India
THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED

FIELD OF THE INVENTION:
The invention relates to a stove and, more particularly, this invention relates to a smokeless stove that utilises fuel like coal, charcoal, cow dung cakes, wood pieces for cooking and various other purpose. The invention provides smokeless functioning and is environment-friendly.
BACKGROUND AND PRIOR ART
Standard charcoal cooking stoves comprise hot coals disposed in the bottom of a firepot and a grill for supporting cooking food mounted adjacent to and directly above the hot coals. Food such as meat, vegetables when exposed to the intense heat for an extended period of time exudes fats and juices which fall onto the coals creating smoke and flames. Primarily because the generation of such smoke is intolerable indoors where ventilation presents a problem the use of charcoal cooking stoves has been limited to the outdoors. As a result, apartment dwellers heretofore have been unable to enjoy charcoal-broiled foods at home and even those having access to outdoor cooking facilities often find the weather to be a limiting factor.
Although prior grill constructions incidentally disclose means for drawing off exuded fats and juices before they impinge upon the heat source, such structures serve only to preserve the fats and juices for later use and are not suitable for preventing the generation of smoke. For example, in U.S. Pat. Nos. 3,973; 850,654; 1,510,547; and 2,940,381, the grills themselves are constructed only to prevent exuded liquids from falling upon the heat source. Such structures have the inherent disadvantage of requiring an inclined rather than horizontal grilling surface and do not prevent smoke because the liquids remain in contact with the hot, heavy guage grilling surface for a time sufficient to heat them to their respective smoking temperatures.
Chinese patent No. CN202374 to Peide Hu discloses smokeless temperature- adjustment carbon stove wherein fan is used as a means to dissipate smoke.
Chinese patent No. CN202365635 to Zhijun Hu discloses smokeless stove wherein the smoke absorbing mechanism for purifying the smoke generated is provided.

There are various patents CN202216290, CN202050842, CN202082967, CN102853458, CN202561818 that discloses various design modification in the charcoal based stove to provide smokeless cooking. None of the cited patents utilised two chamber along with a grill and refractory clay to design simple smokeless stove.
In Indian scenario, where major portion of the population is dwelling in rural areas and uses chulha (stove) as a means of cooking; smokeless stove would be of great importance and at the same time contribute towards cleanliness of the environment.
OBJECT OF THE INVENTION:
An object of the present invention is to provide smokeless stove.
Another object of the present invention is to provide smokeless stove having cooking time just half to that of conventional stove.
Yet another object of the present invention is to provide smokeless stove that do not dissipate smoke and hence is eco friendly.
Still another object of the present invention is to provide smokeless stove that is mobile and portable.
Further object of the present invention is to provide smokeless stove that consumes lesser fuel than the conventional stoves available in the market.
SUMMARY OF THE INVENTION:
The present smokeless stove includes a source of intense heat and a grill mounted adjacent to and above the heat source.
In one aspect of the present invention, the smokeless stove has a cylindrical container opened from the top wherein a grill is arranged onto the top of the cylindrical container; middle of the cylindrical container is provided with a fire grate (made of mesh) for partitioning the cylindrical container into an upper chamber and a lower chamber.

In another aspect of the present invention, four blocks are provided at the top opening of the cylindrical vessel in order to hold the material (or vessel holding the material) to be cooked.
In yet another aspect of the present invention, upper chamber of the cylindrical container is provided as combustion chamber to hold the fuel material (such as coal, charcoal, wood pieces, cow dung cake etc). Upper chamber of the cylindrical container has opening at the front for air intake as oxygen is required to complete the burning process of the fuel.
In still another aspect of the present invention, small door is provided at the upper chamber of the cylindrical container to feed the fuel.
In further aspect of the present invention, lower chamber is provided to hold the residue matter (ash, wood pieces, particulate matter etc) of the burnt fuel.
In still further aspect of the present invention, four wheels are provided at the bottom of the cylindrical vessel to make smokeless movable from one place to another.
In another aspect of the present invention, an adjustable handle is provided at the vertical wall of cylindrical container to facilitate easy carrying of the smokeless stove.
The present cooking stove is particularly suitable or use when charcoal serves as the source of intense heat; however, the advantages of the present stove may also be achieved with other sources of intense heat which accomplish cooking primarily by coal, wood pieces, cow dung cake.
The cylindrical container is made of metal coated with a mixture of refractory clay and glass wool in order to absorb the heat generated during cooking operation could damage the user when smokeless stove become too hot from outside.

BRIEF DESCRIPTION OF DRAWINGS
In the drawing:
FIG. 1 is a perspective view, with parts of a smokeless stove assembly according to this invention.
DETAILED DESCRIPTION OF THE INVENTION:
Referring now to the drawings, in the design of smokeless stove described in the invention is illustrated and generally indicated at in FIG. 1. As will hereinafter be more fully described, the smokeless stove (30) is a cylindrical container (21) opened from the top. Grill (22) is provided at top portion of smokeless stove (30).
Four blocks (20) are provided at the top opened portion of the cylindrical container for the purpose of holding material (vessel containing material) to be cooked. Middle portion of cylindrical vessel is divided into two upper portion and lower portion. Upper portion (31) of the cylindrical container used as combustion chamber has opening (23) for the purpose of providing aeration required for burning of fuel matter. Small door (27) is provided in the upper portion to feed the fuel matter. Lower portion (32) of the cylindrical container has opening (25) for the purpose of collecting burnt material (ash, coal pieces etc.) of the fuel. Upper and lower portion are separate with a fire grate (mesh) (24), providing platform to fuel material in combustion chamber and allowing ash to pass onto the lower portion (32). Four castor wheels (28) are provided at bottom of the cylindrical container (21) for the purpose of moving smokeless stove from one place to another. An adjustable handle (40) is provided at the vertical wall of cylindrical container (21).
Smokeless stove (30) is made of metal coated with a mixture of clay and glass fibres to provide insulation to the vertical walls of cylindrical container so that it retains the heat generated during use of smokeless stove and user may not get damaged due to heat while using it.
