Abstract

The utility model relates to a cavity pipe type energy-saving hot water kettle. The kettle bottom is provided with a smoke division opening. The diameter of the smoke division opening is one quarter of the diameter of the order of kettle bottom. The upper part of the smoke division opening is provided with a cavity pipe which is directly led to the upper part of the back of the opposite side of the kettle. The cavity pipe forms a circular arc shape. The lower part of the cavity pipe is large, and the upper part of the cavity pipe is small. The utility model shortens the time to boil boiling water, and the energy utilization improves 14.2%.

Description

Cavity energy-saving thermos bottle

The utility model relates to a kind of lumen formula energy-saving boiling water kettle, belongs to the technical field of cooking utensil.

Raising along with scientific and technological level, stove and accessory fuel aspect all there is improvement, aspect the hot-water bottle of family expenses, do not have any change for method that boils water and utensil, energy utilization rate is lower, has only less heat exchange area mainly due to flame and high-temperature flue gas and kettle shell, a lot of for the method that increases heat exchange area, be difficult to aspect practical satisfactory, use product always because hot-water bottle is a low value, its main body usually is a casting forming, and cost is low, if adopt new heat transfer technology to increase its cost, meet some difficulties in the market sale meeting.

The purpose of this utility model is that a kind of lumen formula energy-saving boiling water kettle will be provided, and it can overcome above-mentioned shortcoming, and its cost is not increased in its improvement, but can improve the utilization rate of thermal source.

The purpose of this utility model is to realize like this, the smoke-dividing hole of diameter 1/4 at the bottom of the center of ordinary canteen opens a diameter to be kettle, chew the kettle of opposite side at lumen that a convergent is housed on the smoke-dividing hole and water after the upper end communicate, the shape of lumen is that the bottom is big, top is little, and diameter proportion is 3:1.

Fig. 1 is a lumen formula energy-saving boiling water kettle.

Now in conjunction with the accompanying drawings the structure of lumen formula energy-saving boiling water kettle is described in detail:

By Fig. 1, the kettle body (1) of hot-water bottle left side has Hu Zui (2), top pot lid (3) and kettle to be arranged (4), and kettle still uses (4) and kettle body (1) upper end rivet (7) fixing.A smoke-dividing hole (5) is set in the bottom of kettle, its diameter is approximately 1/4 of diameter at the bottom of the kettle, a lumen (6) is set on smoke-dividing hole (5), lumen (6) is a garden arc, the bottom is big, top is little, and the diameter ratio is approximately 3:1, and the upper end communicated after the upper end of lumen (6) and kettle were chewed the kettle of opposite side.

The hot-water bottle of this structure can be introduced the lumen heat exchange to a part of high-temperature flue gas, because lumen is through the kettle heart, the hot and cold water convection current situation in the kettle that makes trends towards complicated more, make the temperature of whole kettle of water raise more even, thereby the mean temperature difference of heating is increased, because the heat exchange area of flame and flue gas and kettle increases, and the heat exchange process of flue gas also increases, therefore the heat transfer intensity of whole kettle also increases in addition.

Through test, this hot-water bottle can shorten the time of heating up water, and makes energy utilization rate improve more than 14.2%.

The material of kettle teapot can be selected stainless steel, cast iron or aluminium for use, and is identical with general kettle commonly used.

Compared with prior art, cavity energy-saving thermos bottle has following advantages:

1. simple in structure, do not increase manufacturing cost.

2. energy utilization rate can improve 14.2%.

3. shorten the time that boils water.

Claims

1, a kind of lumen formula energy-saving boiling water kettle, it is by the kettle body, Hu Zui and pot lid, kettle form, it is characterized in that at the bottom of the kettle smoke-dividing hole (5) being set, a garden arc lumen (6) is set on smoke-dividing hole (5), the upper end communicated after lumen (6) and kettle were chewed the kettle of opposite side.

2, hot-water bottle according to claim 1 is characterized in that lumen (6) bottom is big, top is little, and its diameter is than being 3:1.

3, hot-water bottle according to claim 1, the diameter that it is characterized in that smoke-dividing hole (5) be at the bottom of the kettle diameter 1/4.
