Abstract

The utility model relates to a hot water kettle which is composed of a kettle body, a kettle mouth, a kettle cover and a handle. The utility model is characterized in that the inner cavity of the kettle body is provided with a plurality of fire pipes whose two pipe openings are respectively welded on the bottom of the kettle body and the top surface of the kettle body. When the water is boiled, the flame penetrates through the fire pipe from the bottom, and the flame is exhausted from the top of the kettle top. The utility model has the advantages of large heat transfer area, few residual loss, energy saving, and short water boiling time.

Description

Energy saving kettle

The utility model relates to household goods, is specially a kind of energy-saving boiling water kettle.

Existing is that the family of thermal source boils water and uses hot-water bottle with combustion gas and fire coal, generally all is made of the barrel-shaped kettle body, pot lid and the handle that have Hu Zui.When boiling water, flame is at the kettle base burning, and the bottom surface of heat by kettle passed to cold water in the kettle body intracavity, makes its intensification, until boiling.This hot-water bottle, because heat transfer area only limits to the kettle bottom surface, heat transfer area is little, and flame can only be absorbed the part heat at the bottom of kettle, still having a large amount of unabsorbed waste heats leaves around kettle after the kettle bottom surface stops, not only cause the waste of heat energy, and the water temperature rate of climb is slow, the cold water that generally boils 4 kilograms 15 ℃ needs about 30 minutes time.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of heat transfer area big, and the waste heat loss is few, energy savings, and water temperature rises fast, the hot-water bottle that boiling time is short.

The hot-water bottle that the utility model provides, its main points are, the fire tube that the many two ends mouths of pipe are welded on kettle body bottom surface and kettle body end face respectively is set in kettle body intracavity.

Accompanying drawing is depicted as structural representation of the present utility model.Wherein Fig. 1 is its stereogram, and Fig. 2 is the distribution map of the fire tube mouth of pipe in the kettle bottom surface, and Fig. 3 is the distribution map of the fire tube mouth of pipe at the kettle end face, and Fig. 4 is a kettle base front surface view, and Fig. 5 is along Fig. 4 A-A cutaway view.

In conjunction with Fig. 1 to Fig. 5, the detailed structure of the hot-water bottle that the utility model provides is: be provided with 21 fire tubes (3) in the inner chamber of kettle body (1), for make these fire tubes increase length not influencing under the prerequisite that flame passes through as far as possible, these fire tubes Cheng Xuanzhuan in the kettle chamber is distributed, even the fire tube lower end mouth of pipe is by being divided into three parts among Fig. 3 shown in the dotted line, 7 fire tubes of every part are used a respectively, b, c, d, e, f, g, a ', b ', c ', d ', e ', f ', g ' and a "; b " c "; d " e "; f " " represent it, the upper end mouth of pipe of fire tube distributes by position shown in Figure 4 correspondence g.The bottom surface of colliding with when avoiding kettle to be placed on the table top be welded a longitudinal section around can be at the bottom of the kettle and be become L shaped packing ring (7); In addition, also can be a circular fire holding cycle (9) and packing ring (7) is welded together by a pack support (8).2 is Hu Zui among the figure, and 4 is the fire tube upper orifice, and 5 is handle, and 6 is pot lid.This hot-water bottle can be manufactured with steel, and fire tube is according to the big or small optional φ 6-φ 10mm light-wall pipe of kettle.

The hot-water bottle that the utility model provides, flame burn at the bottom of kettle, and the water in the kettle chamber is passed in the heat absorption earlier of kettle bottom surface, the pyrotechnics that has waste heat enters fire tube from Hu Diguankou, is discharged by Hu Dingguankou, and the waste heat major part is absorbed by water by tube wall, heat transfer area increases several times, and the heat energy utilization rate obviously improves.Evidence is only used less than 10 fens clock times with boiled 4 kilograms of 15 ℃ of cold water of this hot-water bottle, and is energy-conservation more than 50% than the said hot-water bottle of prior art, and the boil water time shortens 2/3rds.

Claims

1, a kind of hot-water bottle that is made of kettle body (1), Hu Zui (2), pot lid (6) and handle (5) is characterized in that, is provided with the fire tube (3) that the many two ends mouths of pipe are welded on kettle body bottom surface and kettle body end face respectively in the inner chamber of said kettle body (1).
