Abstract

The utility model provides an energy saving kettle which comprises a kettle body. The utility model is characterized in that a deep annular groove upward depressed is arranged on the bottom surface of the kettle body. The height of the deep annular groove in the kettle body is greater than one third of the height of the kettle body. Three metal sheets are welded in the deep annular groove on the bottom surface of the kettle body for fixing the kettle body with an inner liner to avoid whipping deformation. The utility model has the advantages of heating area enlargement, high thermal efficiency, reasonable structure, reliable use and energy conservation. The utility model is favorable for environmental protection.

Description

Energy-saving water jug

Technical field

The utility model relates to the hot-water bottle that daily life is used, a kind of specifically energy-saving water jug.

Background technology

Hot-water bottle is widely used in common people's daily life, but existing hot-water bottle since the plane kettle at the bottom of structure limit, heating surface area is too small, has wasted many energy, also causes environmental pollution.And existing energy-saving water jug complex structure, processing inconvenience is not easy to promote.

Summary of the invention

The purpose of this utility model is the deficiency that exists at prior art, and a kind of energy-saving water jug is provided, and increases heating surface area, improves the thermal efficiency, and is rational in infrastructure, is convenient to produce.

The purpose of this utility model is achieved by the following technical solution: a kind of energy-saving water jug, comprise the kettle body, and it is characterized in that described kettle body bottom surface is provided with the degree of depth annular groove to fovea superior.

The height of described annular groove in the kettle body is greater than 1/3 of kettle height degree.

Described kettle body bottom surface is than increasing area more than 180% with the flat kettle of diameter bottom surface.

Three sheet metals of welding in the annular groove of described kettle body bottom surface in order to fixing inner bag kettle body, prevent that whipping is out of shape.

The utility model compared with prior art has many advantages and good effect:

1, the utility model kettle body bottom surface is provided with annular groove, increases heating surface area, and flare is by circular groove upper side circulation heating, distributes after simultaneously most of hot gas revolution externally on the kettle body.Improve the thermal efficiency, saved liquefied gas, coal gas equal energy source, alleviated environmental pollution.

2, three sheet metals of welding in the annular groove of kettle body bottom surface in order to fixing inner bag kettle body, prevent the whipping distortion, use reliably.

3, because the utility model can leave enough scouring incrustation scale spaces, Convenient scrubber wash water dirt in kettle body inside.

4, the utility model energy-saving water jug is rational in infrastructure, but one-shot forming, and production and processing is easy.

Fig. 2 is the vertical view of the utility model energy-saving water jug.

The specific embodiment

Referring to Fig. 1, Fig. 2, be the embodiment of a kind of energy-saving water jug of the present utility model, comprise that kettle body 1, pot lid 2, kettle chew 4, kettle is 3.Kettle body 1 bottom surface is provided with the degree of depth toroidal cavity 6 to fovea superior, and the height of degree of depth toroidal cavity 6 in kettle body 1 is greater than 1/3 (being generally about 1/2) of kettle body 1 height, and kettle body 1 bottom surface is than increasing area more than 180% with the flat kettle of diameter bottom surface.Even three sheet metals 5 of welding in the degree of depth toroidal cavity 6 of kettle body 1 bottom surface in order to fixing inner bag kettle body 1, prevent that whipping is out of shape.During making, the degree of depth toroidal cavity 6 that the energy-saving water jug bottom makes progress is by mould and the 1 time processing moulding of kettle body.Being ventilation, is again heat exchange.

The operation principle of the utility model energy-saving water jug is as follows:

The utility model kettle body is provided with annular groove 6 on 1 bottom surface, and main purpose is to increase heating surface (area) (HS, and flare both can have been realized heating by annular groove 6 upper side, distributes after simultaneously most of hot gas revolution externally on the kettle body 1.In conjunction with the aerodynamics theoretical research, air is originally under the effect of conical flow flare, air itself certainly leads to intermolecular mutual collision according to the increase owing to entropy in hot two laws, the result can cause the annular groove 6 inner temperature difference or the energy differences of constantly producing, can constantly do work, produce phenomenons such as compressional wave → dilatational wave → shock wave → flow apart, particularly end stream spreads role, like this under no passage state, the heat heating that in annular groove 6, can constantly circulate, simultaneously, distribute externally after most of hot gas turns round and repeat heating on the kettle body 1.Its advantage is: both increased heating surface area, improved heat energy efficiency again.

The economic benefit of the utility model energy-saving water jug and environmental benefit:

Calculate with the three-person household kettle of heating up water every day, amount 400,000,000 families, the whole nation, calculate with liquefied gas, save 50% energy every day, press 4 yuan of calculating of per kilogram liquefied gas, 0.32 yuan of the every Hu Shui of ordinary canteen (20 minutes/0.09kg of single kettle gas consumption) is if use energy-saving water jug, the average annual energy-conservation expense of each household is (0.32 yuan * 50% * 365 day) 58 yuan, and it is 23,200,000,000 yuan that China's people's integral body is reduced expenses.From environmental angle, reduce room air pollution in a large number, reduce disease and take place, protected people's environment.

Energy-saving water jug of the present utility model is especially obvious, energy-conservation more than 50% to sealing cooking stove energy-saving effects such as coal stove, bavin firewood stoves.China's population 60% is people in the countryside, and coal stove and bavin firewood stove are main body, and 2.4 hundred million family farmers' use this energy-conservation stove, will go back blue mountains and green waters, the fine boundary that the grassland is fertile.The economic and technical norms and the environmental protection index of the utility model energy-saving water jug are as follows:

1, on the gas stove energy-conservation about 50%;

2, energy-conservation more than 60% on the honeycomb briquet stove;

3, the thermal efficiency be conventional kettle 1.5-2 doubly;

4, CO emission is 0.015%;

(annotate: 1, national regulation burning appliance CO emission can not surpass 0.05%; 2, the carbon monoxide degree of depth discharge capacity of common flat kettle is 0.046%.)

The utility model energy-saving water jug production cost increases about 8 yuan, and sale price can increase about 20 yuan.Use this product can save about 58 yuan of expenses such as liquefied gas, coal gas every year, so economic benefit, social benefit are very considerable.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example.Those skilled in the art are in essential scope of the present utility model, and the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
