Abstract

A multifunctional household boiler comprises a water jacket furnace. A water jacket hearth (8) is equipped in the front of the water jacket furnace and a water jacket chimney (4) is in the tail with an exhaust smoke pipe (3) on the top. An inlet pipe port (9) is on the wall of the water jacket furnace in the water jacket hearth (8), and an outlet pope port (2) is equipped on the surface of the water jacket chimney (4). The boiler is characterized in that a smoke passage (7) is formed by the external wall of the water jacket hearth (8) and the water jacket furnace. Two smoke turn ports (10) which communicate the gas passage (7) are fixed at the two side walls of the water jacket hearth (8). An oven (5) is positioned in the middle of the water jacket chimney (4) and the two side walls of the oven (5) and the inside wall of the water jacket chimney (4) form the gas passage. The opening of the oven (5) is fixed on one side wall of the water jacket chimney (4).

Description

The multifunctional household boiler

Technical field

The utility model belongs to the improvement of residential coal combustion boiler structure, particularly the multifunctional household boiler.

Background technology

At present, the used a lot of residential coal combustion boilers of northern China cold district all have been transformed into water jacket furnace with body of heater one after another in order to improve the heat energy utilization rate, utilize the utilization rate of the interior heat energy that coal burning discharges of circulation heat absorption raising burner hearth of water in the water jacket furnace, make the residential coal combustion boiler not only can cook, heat up water, and improved its heating capacity, be very easy to people's life.However, the heat energy utilization rate of conventional domestic boiler is still not high, and its flow of flue gas direction also has the improved place of needs, also is necessary on the function of use to further expand.

The utility model content

The purpose of this utility model is to provide a kind of multifunctional household boiler, and is not only simple in structure, easy to manufacture, and integrate heating, cook, heat up water, all functions of baked goods, heat energy utilization rate height is for people's life provides great convenience.

The purpose of this utility model is achieved in that a kind of multifunctional household boiler, comprise water jacket furnace, be the water jacket chimney for its rear portion of water jacket burner hearth in water jacket furnace anterior, on the end face of water jacket chimney pipe is being set, on the water jacket furnace body wall of water jacket burner hearth side water inlet pipe mouth is being set, on the end face of water jacket chimney effluent pipe mouth is being set, constitute exhaust gases passes between the outer wall of water jacket burner hearth and the water jacket furnace, the flue gas that is connected with the exhaust gases passes mouth of turning back is being set respectively in the water jacket furnace front left and right sides wall upper end near the water jacket furnace antetheca; Horizontal baking box constitutes exhaust gases passes respectively between the left and right sides wall of baking box and the water jacket inner wall of stack in water jacket chimney middle part, and the opening of baking box is positioned on the sidewall of water jacket chimney.

When the utility model uses, coal is dropped into the water jacket furnace chamber inner combustion, a large amount of heat energy that coal burning produces heat the water in the water jacket furnace earlier, simultaneously the flue gas that is provided with by water jacket burner hearth antetheca left and right sides wall upper end of a large amount of high-temperature flue gas of producing of the coal burning mouth of turning back enters the exhaust gases passes that constitutes between water jacket hearth outer wall and the water jacket furnace, flue gas enters in the water jacket burner hearth and flows forward after flow direction in the exhaust gases passes is served as reasons, and makes the flow of flue gas direction become tortuous circuitous; The flue gas that enters in the exhaust gases passes heats once more to the water in the water jacket furnace again, has prolonged the heat absorption time of water in the water jacket furnace, has improved the heat energy utilization rate.At last, the flue gas that still carries part of waste heat enters the water jacket chimney water in the water jacket chimney is heated heating oven simultaneously, cooking food.Therefore, the utility model is keeping under the boiler structure prerequisite simple, easy to manufacture, integrate heating, cook, heat up water, all functions of baked goods, the heat energy utilization rate is than traditional domestic boiler height, for people's life provides great convenience, use in the vast town and country that are particularly suitable for the northern China cold district.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 looks cross-sectional view for master of the present utility model;

Fig. 2 is the A-A cross-sectional view among Fig. 1.

The specific embodiment

A kind of multifunctional household boiler as shown in Figure 1 and Figure 2, comprises water jacket furnace, and the anterior interior of water jacket furnace is being provided with pipe 3 for water jacket burner hearth 8 its rear portions are water jacket chimney 4 on the end face of water jacket chimney 4, and the bottom of water jacket chimney 4 is being provided with cleaning door 6.The bath water mouth of pipe 1 also is being set on the end face of water jacket chimney 4, is using the use hot water of having a bath for people.The below of water jacket burner hearth 8 is being provided with ashes chamber 12, in order to admit ashes.On the water jacket furnace body wall of water jacket burner hearth 8 sides water inlet pipe mouth 9 is being set, effluent pipe mouth 2 is being set on the end face of water jacket chimney 4, water inlet pipe mouth 9 is connected with the room heater pipeline respectively with effluent pipe mouth 2, uses for heating of house.

As shown in Figure 1 and Figure 2, constitute exhaust gases passes 7 between the outer wall of water jacket burner hearth 8 and the water jacket furnace, exhaust gases passes 7 is connected with water jacket chimney 4 bottoms.The flue gas that is connected with exhaust gases passes 7 is being set respectively in the water jacket burner hearth 8 anterior left and right sides walls upper end near the water jacket furnace antetheca is turning back mouthfuls 10, the high-temperature flue gas that coal burnings produce in the water jacket burner hearth 8 is turned back through flue gas and mouthfuls 10 is entered exhaust gases passes 7, make the flow of flue gas direction become tortuous, help prolonging the heat absorption time of the water in the water jacket furnace, improve the heat energy utilization rate.

In order further to utilize the waste heat of flue gases in the water jacket chimney 4, horizontal baking box 5 constitutes exhaust gases passes respectively between the left and right sides wall of baking box 5 and water jacket chimney 4 inwalls in water jacket chimney 4 middle parts, and the opening of baking box 5 is positioned on the sidewall of water jacket chimney 4.Like this can also be in baking box 5 the various foods of baking, enriched function of use of the present utility model, for people's life is provided convenience.
