Abstract

The utility model relates to a teakettle with high thermal conductivity, which comprises a teakettle body, a spout, a teakettle cover and a handle, wherein the bottom part of the body is concave inwards in a trapezoid or a conic shape. Therefore, the teakettle increases the heat transfer area, and further improves the heat transfer efficiency, thus achieving the aims of saving energy and improving the efficiency.

Description

The kettle teapot of modified high thermoconductivity

[technical field]

The utility model relates to a kind of kettle teapot, more particularly, relates to a kind of kettle of modified high thermoconductivity.

[background technology]

Family generally all makes electricity consumption water dispenser or kettle teapot heat the drinking water source mostly.Wherein most of family all uses kettle teapot to add hot tap-water with external heat source.Owing to use external heat source, heat must conduct to the running water of kettle inside from the kettle teapot bottom.Certainly, in order to improve the thermal source service efficiency, people have expected that a lot of ways improve stove and accessory, and its combustion gas utilization ratio is improved, and reach the purpose that conserve energy is raised the efficiency.Present kettle teapot all is the common kettle teapot of circular flat bottom, and when heating up water, heat utilization ratio is low, wastes energy.The inventor expects equally also can trying every possible means by improving the structure of heating container (kettle teapot), realize identical purpose, mentioned in the application of the former proposition of inventor kettle body bottom has been fabricated to fold shape, and then the increase heating surface area, improving heat transfer efficiency, it has certain effect, but at the energy of advocating thriftiness, the current society that raises the efficiency, people wish to obtain higher heat transfer efficiency, utilize the energy more fully.

[summary of the invention]

To achieve these goals, here, the inventor has designed a kind of follow-on kettle teapot, it has greatly increased the heating surface area of kettle, and has improved the form of thermal convection current in the kettle body, has greatly improved heat utilization efficiency, improve heat transfer efficiency, saved the energy better, improved the efficient of heating up water.

Specifically, the utility model provides a kind of kettle teapot, comprise kettle body, Hu Zui, pot lid and handle, the body bottom manufactures and caves inward, increase heating surface area whereby, improve thermal cycle, thermal convection current in the kettle body, the final raising pyroconductivity that realizes, energy savings, the purpose of raising the efficiency.

In a preferred embodiment, the bottom of described body is manufactured into the prismatoid that caves inward, because prismatoid has certain altitude, trapezoidal body wall around this height becomes heating surface, under the situation of big or small on an equal basis floor space, increase this height and just can increase thermal interface, thereby, heat transfer efficiency improved; In addition, than traditional flat kettle, kettle body internal structure changes, and the heat conduction no longer is from planar base, upwards conducts heat, but from prismatoid each towards around conduct heat, this heat transfer pattern has changed thermal convection current, thermal cycle form, makes water convection velocity quickening in the kettle body, like this, under the situation of same external heat source, adopt the efficient of heating up water of kettle of this convection model higher.

In another preferred embodiment, the bottom of described body is manufactured into the cone that caves inward, and its principle is similar with the prismatoid of above-mentioned embodiment.But owing to adopt conically shaped body, it is comparatively different with prismatoid that heat outwards conducts the convection current, the circulation that cause, adopt this conical physical efficiency to improve the thermal convection current form better, more can improve the water convection velocity, realize the heat up water efficient higher than above-mentioned prismatoid embodiment.

Principle of the present utility model is that the shape that caves inward is made in the kettle teapot bottom surface, and described shape comprises all shapes that can realize the utility model purpose.

By the embodiment of such scheme, the utility model improves heat conduction efficiency when heating up water by improving the kettle body structure, has realized energy savings, the purpose of raising the efficiency.

Fig. 2 is the schematic diagram of second preferred embodiment of the utility model kettle teapot and the upward view of described kettle teapot body bottom.

[specific embodiment]

With reference to Fig. 1, first preferred embodiment of the kettle teapot of modified high thermoconductivity of the present utility model is shown, described kettle teapot 20 comprises kettle body 21, kettle mouth 22, pot lid 23 and handle 24.Specifically, body bottom 25 manufactures the prismatoid 26 that caves inward, because prismatoid has certain altitude h, trapezoidal body wall around this height becomes heating surface, under the situation of big or small on an equal basis floor space, increases this height and just can increase thermal interface, thereby, improve heat transfer efficiency; In addition, than traditional flat kettle, kettle body internal structure changes, and the heat conduction no longer is from planar base, upwards conducts heat, but from prismatoid each towards around conduct heat, this heat transfer pattern has changed thermal convection current, thermal cycle form, makes water convection velocity quickening in the kettle body, like this, under the situation of same external heat source, adopt the efficient of heating up water of kettle of this convection model higher.

With reference to Fig. 2, second preferred embodiment of the kettle teapot of modified high thermoconductivity of the present utility model is shown, the bottom 25 of described body is manufactured into the cone 27 that caves inward, and its principle is similar with the prismatoid of above-mentioned embodiment.But owing to adopt conically shaped body 27, it is comparatively different with prismatoid that heat outwards conducts the convection current, the circulation that cause, adopt this conical physical efficiency to improve the thermal convection current form better, more can improve the water convection velocity, realize the heat up water efficient higher than above-mentioned prismatoid embodiment.

In the use, kettle teapot of the present utility model is placed on the conventional external thermal source, just can improves heat transfer efficiency, accelerate the speed of heating up water.
