Abstract

The utility model relates to an internal and external heating type high efficient water-boiling kettle, which is composed of a kettle body, a spout, a handle and a kettle cover. The kettle bottom is provided with a fire collecting cavity, and a hot water pipe past through the kettle cavity is arranged between the fire collecting cavity and the kettle wall. The heat collecting cavity has a convex cavity type and a horn cavity type, and the hot water pipe has a bent type, a straight type, an arc type and a spiral type. The heating area is large and the heat circulation and heat exchange are sufficient, so heating water has energy conservation, high efficiency and high speed.

Description

Internal and external heating type high efficient water-boiling kettle

The utility model relates to a kind of interior external-heat efficient kettle.

General kettle bottom surface is the plane, comes hot water by adding the hot-water bottle bottom, belongs to the external-heat kettle, and it is simple in structure, but heat utilization efficiency is low, and when big hyperactivity of fire, kettle bottom fire area is not enough especially, and many heat energy are run away in vain.

The purpose of this utility model is that a kind of interior energy-efficient kettle of external-heat is provided at above-mentioned deficiency.

The utility model is to realize like this, kettle chamber, hot-water line external diameter one end and the fire collecting cavity sealed attachment of passing through the kettle body to the fire collecting cavity hot-water line of kettle chamber projection is set in the bottom of kettle body, the kettle wall sealed attachment of the other end and kettle body, the height of connector is in the 1/2-3/4 of kettle body total height.

Description of drawings:

Fig. 1 is the main cutaway view of a kind of embodiment of the utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the front view of the another kind of embodiment of the utility model.

Fig. 4 is the B-B cutaway view of Fig. 3.

Now illustrate in detail with regard to structure of the present utility model and principle thereof in conjunction with the accompanying drawings:

The utility model is owing to be provided with fire collecting cavity 5, and when stove fire burn, its fire combustion and heat energy had become concentrated shape by the dispersion shape of general flat kettle, also is like this even the external world has under the situation of wind.Load onto hot-water line 6 on the top of fire collecting cavity again, hot-water line 6 communicates with the Hu Bi of kettle body 1 after passing through the kettle chamber, and fire collecting cavity 5 is the water in the heating kettle chamber directly, can also make hot gas heat be passed to water in the kettle chamber through hot-water line 6.Become simple external-heat and be inside and outside hot type, more help the abundant exchange of heat.

Fire collecting cavity 5 both can have been made the protruding chamber that is surrounded by the conical surface (or cambered surface) 7 and plane 8 shown in the accompanying drawing 1,2 and constitute the conical surface 7 and be connected with the Hu Bi of kettle body 1, and plane 8 is connected with the conical surface 7, also can make Fig. 3, shown in Figure 4 by tubaeform.Also can make other shape, convex to form a cavity to the kettle chamber at the bottom of the kettle as long as guarantee.The former is because protruding chamber is shorter, hot-water line 6 best lower ends and 7 vertical connections of plane, this section pipe has certain height, but the circulation of the favourable hot gas of exhausting, the upper end basic horizontal, pipeline is longer, can prolong the time of heat exchange, and favourable heat energy fully exchanges, it is connected with Hu Bi, the angle of hot-water line top and bottom is between 80 °-110 °, and the upper end partly can be made linear but preferably with certain radian, can be prolonged its length.Use arc transition between the upper and lower end.The flexible in size setting of the visual caliber of hot-water line 6 quantity, but should be symmetrically distributed as far as possible; Hot-water line 6 also can pick out and adopt a taper thread version from the center of fire collecting cavity 5, little top, bottom is big, by communicating with the external world through Hu Bi in the kettle chamber.Fig. 3 fire collecting cavity 5 shown in Figure 4 is higher, itself has certain exhausting ability.Therefore hot-water line 6 is straight pipe type or curved pipe, can make kettle chamber and kettle wall sealed attachment that width of cloth bar formula is passed through the kettle body by the top of fire collecting cavity 5, and the quantity of hot-water line 6 and distribution are as hereinbefore; Also hot-water line can be made a snail formula, the center communicates with horn mouth top, is connected with Hu Bi after passing through the kettle chamber.The height of the above hot-water line 6 and kettle wall link position is at 1/2nd to 3/4ths places of kettle body total height.

Maximum advantage of the present utility model is to become external-heat into interior external-heat, has strengthened the area that is heated, and has accelerated heat exchange and type of thermal communication, therefore heats or boiled water with it, and is quick and energy-conservation. Heat-barrier material is coated on other surface at kettle except fire collecting cavity, and effect is better.
