Abstract

The utility model relates to a coal-fired and water heating stove, which belongs to the technical field of daily stoves. The utility model is composed of combined water jackets (1), secondary air passages (2), an internal stove (3), heat insulation layers (4), stove bars (5) and an outer casing (6). The utility model is characterized in that a main body of the stove is composed of combined water jackets which are composed of annular water jackets, cylinder-shaped water jackets and gourd ladle-shaped water jackets; the internal stove is arranged in the water jackets. The utility model can use any briquette as fuels and can use powder coal as fuels too. The utility model can be used for heating in winter, can be used for supplying hot water for bath and can be used for washing dishes in summer besides cooking.

Description

The type dual-purpose coal-fired hot-water heating kitchen range that looses

The utility model belongs to daily cooking stove class technology.

At present, the cooking stove in the society mostly can not be warmed oneself, and the hot-water heating stove can not cooking, especially middle-size and small-size restaurant be badly in need of a kind of can heating again can cooking new kitchen range.

The purpose of this utility model be design a kind of be fuel with commercially available various moulded coals (honeycomb briquette, the coal briquette) coal that looses, have the novel hot-water heating cooking stove that hot-water heating, cooking, the multiduty few cigarette of economizing on coal of steamed rice, low dirt do not pollute indoor environment.

The purpose of this utility model is achieved in that with refractory material makes flue, and courage is surrounded by the minimum refractory material of thermal conductivity factor outward, this insulation flue is placed on by ring-shaped water jacket, tubular wood cover and wooden dipper shape water jacket forms on the fire bars in the combined water jacket of one.Filled heat insulating material between water jacket and shell, and it is contained on the shelf.Be connected to evacuated tube on the ring-shaped water jacket to connect atmosphere.On ring-shaped water jacket, be equipped with outlet pipe again, outwards heat supply water.Lower end at wooden dipper shape water jacket is equipped with feed pipe, supplies water in water jacket.Above fire door interior an air channel is arranged, straight-through fire door provides hot blast to fire door.Hot blast with enter ring-shaped water jacket after the gas of uncombusted mixes in flue, in flue, carry out second-time burning, play the double action that eliminates smoke and improve the thermal efficiency.

Further specify below in conjunction with accompanying drawing.

Accompanying drawing 1 is a vertical section of the present utility model schematic diagram.Wherein 1 is combined water jacket, and 2 is secondary air duct, and 3 is flue, and 4 is heat-insulation layer, and 5 is fire bars, and 6 is shell.

Accompanying drawing 2 is combined water jacket schematic diagrames of the present utility model, and accompanying drawing 3 is flue schematic diagrames of the present utility model.Wherein 1 is the moulded coal flue, and 2 is the Loose-coal stove courage.

Characteristics of the present utility model are to improve furnace temperature as much as possible, and interior all combustibles of coal are all burnt, and a liberated heat part is made the thermal source of cooking, and waste heat is absorbed by water jacket as much as possible, carries out heating.

Burning is from bottom to top.Coal is in the flue internal combustion, and the unburnt imflammable gas of emitting divides in four tunnel the flues in ring-shaped water jacket to burn away after secondary hot-air mixes, and liberated heat is absorbed by ring-shaped water jacket, thereby ring-shaped water jacket is the highest part of temperature in the combined water jacket.So outwards export hot water thus.Wooden dipper shape water jacket makes progress reflecting heat to improve furnace temperature.Accept the heat that the coal-fired width of cloth is downwards penetrated simultaneously.This heat is absorbed by the water in the water jacket.Feed pipe by wooden dipper shape water jacket bottom supplies water to water jacket, by the tubular water jacket warm water is constantly replenished to ring-shaped water jacket, to finish the circulation of water.The water jacket planted agent uses soft water (or boiling water) that softening method is not had specific (special) requirements.

On ring-shaped water jacket fire door, bell.Opening bell just can cooking, and a kitchen range is dual-purpose.

Claims

The type dual-purpose coal-fired hot-water heating kitchen range that looses is characterized in that having one by the be welded combined water jacket of one of the ring-shaped water jacket that includes flue, tubular water jacket and wooden dipper shape water sleeve spirality secondary wind channel.
