Description

The split type energy-saving water jug of a kind of strong convection

[technical field]

The utility model relates to the split type energy-saving water jug of a kind of strong convection.

[background technology]

Mainly be to rely on that heat absorption and heat transfer heat up water at the bottom of the kettle when family expenses ordinary canteen is heated up water; The heat that fuel combustion passes to water in the kettle is directly proportional with heat transfer coefficient, kettle floor space and heated time; And concerning same firepower with the kettle of material, heat transfer coefficient is constant, and kettle floor space and heated time are depended in the rising of water temperature; And the two is a pair of factor that is inversely proportional to. (be that the greatly then required heated time of kettle floor space is short, the utilization rate of fuel is high; Otherwise then the time long, the utilization rate of fuel is low).

Mostly existing market is flat kettle, and the contact area of itself and thermal source is little, and fuel availability is low, and for gas-cooker, and it is low that the flame of its burner has middle flame, the characteristics that outer ring flame is high, and kettle is set to that flat that it will be heated will be irregular, wastes energy.

Existing energy-saving water jug is on the kettle body, to open several exhaust gases passes mostly, and to increase heating surface area, this kettle energy-saving effect is not only not obvious; And complex structure, difficulty of processing is very big, and particularly the kettle body is owing to be provided with exhaust gases passes; Volume receives very big influence, has adorned not how much water.

[utility model content]

The utility model technical problem to be solved is to provide a kind of strong convection split type energy-saving water jug, and the convection current of fortified water water-in-kettle further improves the thermal efficiency, shortens heat time heating time, reaching purpose of energy saving, and guarantees that as much as possible the volume of kettle is enough big.

The technical scheme of the utility model is: the split type energy-saving water jug of a kind of strong convection; Comprise outer kettle and interior kettle; Said interior kettle is flush-mounted in said outer kettle bottom and connects as one; Hu Hukou is arranged in the said outer kettle inner chamber in said, and the Movable valve that just can open when only the water of kettle seethes with excitement in said is equipped with at said interior Hu Hukou place.This Movable valve be under normal conditions under resetting-mechanism or own wt effect, close said in Hu Hukou, during water boiling in said in the kettle, this Movable valve is backed down by boiling water, makes the inner chamber connection of said outer kettle and interior kettle.

The principle of the utility model is: we know; The heat-conductive characteristic of water is relatively poor, mainly by convection action water temperature of each several part when being heated is evenly risen, and kettle is when heating up water; At first be the water that adds the hot-water bottle bottom; Density diminished after hot water reached uniform temperature, began upwards to flow, thereby formed convection current.The utility model is exactly the water of kettle in the heating, backs down Movable valve after waiting its boiling, mixes formation hot water with the water of outer kettle; Strengthen the convection current of outer water-in-kettle, the water in the kettle is heated rapidly, shorten heat time heating time; The heat that reduces in the heating process scatters and disappears, and reaches purpose of energy saving.

As the further improvement of such scheme, the volumetric ratio of said outer kettle and interior kettle is 2: 1～3: 1.

Another kind as such scheme improves, and leaves the slit between said outer kettle bottom and the interior kettle bottom, thereby enlarges the heating surface area of kettle, improves the thermal efficiency.

As the further improvement of such scheme, said outer kettle bottom outer rim protrusion 3～5cm downwards forms firestopping ring, prevents that stove fire from outwards flying away along the kettle body, reduces waste of fuel.

The advantage of the utility model is: through the convection current of fortified water water-in-kettle, improves the thermal efficiency of kettle, compares with traditional kettle, and energy-conservation, save time, reduce toxic emission, and guarantee that as much as possible the volume of kettle enough uses.
