, Description:FIELD OF INVENTION:

This invention relates to a Liquefied Petroleum Gas (LPG) / Induction Stove/ Coal Stove coffee maker which can be used for domestic as well as commercial purpose.

BACKGROUND OF THE INVENTION

Coffeemakers or coffee machines are cooking appliances used to brew coffee.

Coffee machines, are arranged to circulate liquid, usually water, from a water source that is cold or heated by heating means, to a mixing or infusion chamber where the coffee is actually prepared by exposing the circulating liquid to a bulk or pre-packaged ingredient, for instance within a capsule. From this chamber, the prepared coffee is usually guided to a dispensing area, for instance to a coffee outlet located above a cup or mug support area comprised or associated with the machine. During or after the preparation process, used ingredients and/or their packaging is evacuated to a collection receptacle.

Presently most of the coffee machines consumes electricity for their working.

U.S Patent US 3693535 describes In a pour-in, instant brewing type coffee maker, gravity flow of water, from a receiving tray bottom orifice to an electric resistance heated block of a unit heating the water as it passes to a brewing funnel discharging hot brewed coffee, is controlled by a float-varied orifice structure, and the tray overlies the block for tray water heating by water vapor latent heat; thus eliminating need of a large block mass or excessive heater wattage to provide requisite hot water temperature in an acceptable cycle time, and permitting a simple molded plastic housing design. Baffling in a block water flow top cavity conduces to efficient heat transfer and to reduction of steaming and of attendant noise.

U.S. Patent 5,943,472 discloses a water circulation system for such a machine between a water reservoir and a hot water or vapour distribution chamber, for an espresso machine. The circulation system includes valves, a metallic heating tube and a pump that are interconnected with each other and with the reservoir via a plurality of silicone hoses that are joined together by clamping collars.

EP 0 841 547 discloses a flowmeter commercialized by DIGMESA which is suitable for beverage preparation machines. This flowmeter has a two-part housing with a bayonet connection, the housing containing an inner measuring chamber with a central fixed shaft extending there through for mounting an inner rotatable measuring body with fins that are located in the flow path and that are driven thereby. The flow of liquid passing through the measuring chamber is derived from a measure of the speed of rotation of the rotatable measuring body using a Hall sensor. A drawback of this device lies in the large friction surface between the fixed shaft and the rotating measuring body which changes depending on the orientation of the flowmeter and which also affects the accuracy of the measure of the flow through the chamber.

However none of the above mentioned invention of coffee maker use Liquefied Petroleum Gas (LPG) / Stove/ Coal Stove.

In the industrialized world, as stoves replaced open fires and braziers as a source of more efficient and reliable heating, models were developed that could also be used for cooking, and these came to be known as kitchen stoves. Here in the present invention all types of cooking stoves can be used for the coffee maker

LPG is a convenient and efficient fuel for homes and businesses. LPG is also an environmentally-friendly fuel. Households can more than halve their Green House Gas emissions by using LPG instead of electricity for water heating, cooking or space heating at home.

LPG is a cleaner burning fuel with high combustion efficiency. LPG produces less harmful emissions than many other conventional fossil fuels, meaning it is less harmful to the environment and your health compared to most other conventional fossil fuels. It generates very little CO2 and is low in sulphur, nitrogen and other particulates – all of which contribute to pollution. In the event of a spill, LPG will quickly evaporate with no risk of ground or water contamination. LPG is reliable, portable and flexible so it can be used for a wide range of applications. It provides instantly available heat and is easily controllable, so it’s the ideal alternative to mains gas.

Hence, there is still a need to provide a coffee machine which works on Liquefied Petroleum Gas (LPG) / Stove/ Coal Stove rather than electricity thus providing a cheap source of energy.

The present invention provides to a Liquefied Petroleum Gas (LPG) / Stove/ Coal Stove coffee maker which can be used for domestic as well as commercial purpose.

DETAILED DESCRIPTION OF THE INVENTION:

The present invention provides Liquefied Petroleum Gas (LPG) / Stove/ Coal Stove coffee maker. In contrast to coffee machines, the present coffee machine operate such that the ground coffee is extracted by means of pressurized hot water. Pressure is built up either by the steam pressure of the water heated above the boiling temperature provided by Liquefied Petroleum Gas (LPG) / Stove/ Coal Stove.

Shots of espresso are typically brewed by the pressurized penetration of hot water through densely-packed finely-ground coffee. This forced diffusion of water through coffee grounds, results in the production of coffee.

The present invention of Coffee Maker can be used in all types of Cooking Stoves.

The term “ stove” used herein , usually called a gas range (especially but not only in US English range, cooker, or oven is a kitchen appliance designed for the purpose of cooking food. Kitchen stoves rely on the application of direct heat for the cooking process and may also contain an oven, used for baking.

In main aspect of the present invention provides an LPG coffee maker unit which consists of
1) Water boiler
2) Pressure meter
3) Water release regulator with U shape pipe
4) Pressure alarm with valve
5) Steel net to release heat
6) Water container
7) Upper side cover
8) Gas Stove

In another aspect of the present invention provides an LPG coffee maker unit which consists of water boiler for heating the water to produce steam which is used to make coffee.

The “Pressure meter” used herein is a control valve that reduces the input pressure of a fluid to a desired value at its output. It matches the flow of gas through the regulator to the demand for gas placed upon it, whilst maintaining a constant output pressure. If the load flow decreases, then the regulator flow will also decrease. If the load flow increases, then the regulator flow will increase in order to keep the controlled pressure from decreasing due to a shortage of gas in the pressure system.

The “water release regulator” with U shape pipe used herein is safety valve releasing water (and thus relieves pressure) if either the temperature or pressure in the coffee maker gets too high.

The “pressure alarm” with valve which provides a pressure limit function.

The “Steel net” used herein is used to release heat from the coffee maker.

The “water container” is used to store the water which can produce steam.
The “Upper side cover” used herein is the lid of the coffee maker.

The “Gas stove” used herein is an enclosed space in which fuel is burned to provide heating, either to heat the space in which the stove is situated.

The coffee maker as shown in FIG. 1 comprises a gas stove as heating means with a gas regulator to control the consumption of LPG. The heating means which is here used is normally integrated into a bottom part of the stove. The upper portion consists of the steam boiler with a water container which stores water which further forms pressurized penetration of hot water through densely-packed finely-ground coffee. This forced diffusion of water through coffee grounds, results in the production of coffee. The coffee machine consists of heat release net and the pressure meter and regulator to keep a check on the pressure of the steam.

As shown in Fig 2, with water in the water reservoir, and the coffee grounds in the coffee container, water is heated and pumped to the shower head. Upon heated water reaching the shower head, a forced diffusion of water through coffee grounds in the filter basket occurs, resulting in the production of coffee.

In one of the embodiment as shown in Fig 3, a water regulator pipe is provided for communicating water from the reservoir to the steam boiler. This path includes a U-shaped pipe which communicates water to a pump that supplies water at a pre-determined pressure. A safety relief valve i.e a regulator is included to limit the water pressure provided to the steam boiler.
