Abstract

The utility model relates to a domestic multifunction gas-generating stove which is provided with an air distribution mechanism and a water heating mechanism in the traditional coal gas stove. The air distribution mechanism comprises an upper air channel, a lower air channel, a vertical air channel, an adjustable air valve and a blower fan, and the air extracted from the upper air channel can be used by the water gas generated in the domestic multifunction gas-generating stove to combust. A hot water tank is arranged around a stove opening and a chimney. The domestic multifunction gas-generating stove has the advantages of large coal gas yield, small coal-consumption, high thermal efficiency, simple structure, convenient operation and less pollution, so the domestic multifunction gas-generating stove can be used for heating, bathing and cooking.

Description

Domestic multifunction gas-generating stove

The utility model belongs to a kind of cooking stove.

In the prior art, people are for fuel savings, in order to improve the thermal efficiency, in order to eliminate the pollution that coal smoke brings to environment, design various household fuel gas or semi-coal gas producer, as Chinese patent " the vertical semi-coal gas multifunctional coal-saving stoves of family expenses (2097353U), multifunctional domestic water-gas generators (2096706U), household infrared ray gas generator (2094686U); accumulation of heat blue-gas generator kitchen range (2092688U) and multipurpose self produced gas high-efficient coal-saving stove (2092685U) or the like; they respectively have its excellent characteristics, still, take all factors into consideration; the equal more complicated of their structure; complex operation, volume is big, the cost height.

The purpose of this utility model provides a kind of simple in structure, operation easily, and volume is little, the multifunctional household gas producer that cost is low.

Characteristics of the present utility model are coal-fired few, and institute's producing coal gas is many, and smoke contamination is little, and cooking heating is neglected neither.

The structure of this gas generator is: add a cover air distribution mechanism and a hot-water heating mechanism in coal furnace, but this air distribution mechanism comprises blower fan adjusting valve, lower air duct, straight air channel and upper air duct, blower fan is placed in furnace bottom one side, and lower air duct is a circle shaped tube type, coils in the burner hearth bottom outer wall; Upper air duct is annular round platform formula, is located at roof of the furnace crater place, has several cellular vents on its madial wall, and the bottom connects the straight air channel of 3-6 root and links up upper and lower air channel; But adjusting valve is located on the ventilating duct between blower fan, the lower air duct, the combustion air that it can be unidirectional as required or two-way varies in size to air distribution mechanism and burner hearth bottom wind supply quantity; This hot-water heating mechanism comprises kitchen range top boiler, chimney boiler, water inlet pipe and drainpipe, and kitchen range top boiler is around crater and outlet flue, and profile is cuboid, its upper surface double as kitchen range top; The chimney boiler is located at the periphery of chimney, the inner intercommunication of it and kitchen range top water tank; The water inlet pipe of this hot-water heating mechanism inserts from the bottom of kitchen range top boiler, be the heated time of lengthening water inlet in water tank, water inlet pipe can be located at the kitchen range top boiler bottom that becomes a survey face with chimney, and in the water tank of this side, establish the water-stop sheet that can separate water inlet and outlet flue, make into the water orientation around the kitchen range mouth along circumfluence to the chimney water tank; The drainpipe of this hot-water heating mechanism is located at the top of chimney water tank;

This gas generator can be established one or several auxiliary kitchen range eye, become eyes kitchen range or multi-hole kitchen range, the coal gas of its auxiliary kitchen range eye is supplied with by gas-pipe line, gas-pipe line is a curve bend, its port is located at the first half of inboard wall of burner hearth, the another port is located at the bottom of auxiliary kitchen range eye, and at its outer cover one joint wind collection, so that natural wind is concentrated the supply gas-fired.

Introduce the structure of eyes kitchen range embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 looks cross-sectional view for eyes kitchen range master.

Fig. 2 is Fig. 1 side-looking cross-sectional view.

Fig. 3 is Fig. 1 plan structure schematic diagram.

Fig. 4 is that Fig. 1 is along A-A line schematic cross-section.

Among the figure, 1 is body of heater, interior part two parts, and a part is established burner hearth 2, and Sealing furnace grit chamber 3 and coal filling hole 4 are identical with traditional stove design; Another part is placed blower fan 5, the lower air duct 6 of the air distribution mechanism of this stove coils in burner hearth 2 bottom outer wall, and upper air duct 7 is located at burner hearth crater place, and is round table-like ringwise, have several cellular vents 8 on its madial wall, the bottom connects 4 straight air channels 9 and links up upper and lower air channel; But adjusting valve 10 is installed on the ventilating duct between blower fan 5 and the lower air duct 6; The kitchen range top boiler 11 of this stove hot-water heating mechanism is located on the body of heater 1, and its surperficial double as kitchen range top is established two

kitchen range eyes

12 and 13 on the kitchen range top, establishes the smoke flue 14 and the water fender 15 that lead to chimney in the boiler; 16 is the chimney boiler, and with boiler 11 intercommunications, drainpipe 17 is located at the top of boiler 16, and water inlet pipe 18 inserts from the bottom of boiler 11; Gas-pipe line 19 1 ends in the kitchen range eye 13 are located at the inwall first half of burner hearth 2, and the other end is in the bottom of kitchen range eye 13, and at its outside suit one joint wind collection 20, and port part is established a pipe and covered 21.

The method of operating and the operation principle of this gas generator are: when lighting a fire slag door and coal filling hole are sealed, place bavin in the burner hearth, charcoal is lighted, regulating air-valve makes blower fan to the burner hearth bottom air feed, stove fire is risen prosperous, burner hearth heats up, when certain strong fire in a stove before fuel is added has been arranged, readjust air-valve, make blower fan supply high wind, and supply weak wind to burner hearth bottom to air distribution mechanism, and in stove, add a certain amount of water coal of mixing, just produce water-gas like this in the burner hearth for cooking, the heating usefulness of heating up water during with single-hole range cooking, is added a cover sealing with other kitchen range gugen kohle airway, if when using the eyes kitchen range simultaneously, the supravasal lid that turns on the gas-fire is lighted and is got final product.

Use observation through the practice test, this gas generator institute producing coal gas foot, thermal efficiency height is coal-fired few, and the black smoke that discharges in the chimney is few, can reduce environmental pollution, and its structure is simple than other gas generator, cost is low, and processing ease does not have the danger of gas poisoning to exist yet.
