Abstract
The invention discloses an electric kettle and belongs to the technical field of electric heating. The electric kettle comprises an electric heating disc for heating and a kettle body containing liquid. The electric kettle is characterized in that the contact face between the electric heating disc and the kettle body is a spherical face, the bottom of the kettle body is in the shape of an inward-concave spherical face, the end face of the heating disc is an outward-convex spherical face, and the inward-concave spherical face and the outward-convex spherical face are the same in radian and are in tight fit. The kettle body is made of glass or metal materials. The edge of the electric heating disc is provided with a plurality of rigid supporting columns used for preventing the kettle body from being inclined. A certain gap is reserved between the end faces of the supporting columns and the bottom face of the kettle body. Compared with an existing electric kettle, the heat efficiency of the electric kettle can be effectively improved, the kettle body is easy to center and position when placed, and the kettle body with the plane bottom is not likely to be stuck and polluted when placed on a polluted tabletop. Compared with a large-power external heated plane contact electric kettle, the area of the end face of the electric heating disc is small, and therefore the size of the product is small.
Description
Technical field
The present invention relates to electric-heating technology field, relate in particular to a kind of electric kettle.
Background technology
The electric kettle of prior art, generally include the electric heat-generating disc of heating and the kettle body of holding liquid, kettle body is positioned on electric heat-generating disc, by the heat radiation of electric heat-generating disc, heat is delivered to kettle body, and kettle body water temperature is raised.
External-heat electric kettle is generally plane contact type heating, namely the bottom surface of kettle body and the end face of electric heat-generating disc are all planes, but, external-heat electric kettle is approximate harsh to the bottom flatness requirement of kettle body, only has the flatness fully ensured bottom kettle body, could contact completely with electric heat-generating disc, but because of the restriction by current processing technology and technology, the difficulty of processing of the flat accuracy of the bottom of kettle body is maximum, and therefore, the thermal efficiency is not high.Its two, place kettle time be difficult to centering location, namely need to increase other central tube bit architectures; Its three, kettle is placed on the desktop of dirt, and the kettle at the bottom of plane is easy to pickup; Its four, for high-power external-heat plane contact electric kettle, the face area of its electric heat-generating disc is also larger, and thus the volume of product is also larger.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of electric kettle is provided.Compared with existing electric kettle, this electric kettle can improve the thermal efficiency effectively, and easy centering location when placing kettle, kettle is placed on the desktop of dirt, and the kettle at the bottom of plane is not easy by pickup; Relative to high-power external-heat plane contact electric kettle, the face area of its electric heat-generating disc is smaller, and thus the volume of product is also smaller.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric kettle of the present invention, includes the electric heat-generating disc of heating and the kettle body of holding liquid, distinguished: the contact surface of described electric heat-generating disc and described kettle body is Surface of Sphere; Wherein, bottom of water kettle shape is indent Surface of Sphere, and heat-generating disc end face becomes evagination Surface of Sphere, and both radians are consistent and fit tightly.
Described kettle is glass material or metal material.
The edge of described electric heat-generating disc is provided with several rigid support posts for preventing kettle from tilting; Certain gap is left in end face and the kettle bottom surface of described support column.
Above technical scheme can be found out, compared with prior art, the advantage of electric kettle of the present invention is: 1, electric kettle of the present invention, bottom of water kettle shape is interior concave spherical surface, heat-generating disc is outer convex spherical, and both unanimously fit tightly by radian, and heat conduction efficiency is high.2, kettle is placed conveniently.Be placed on by kettle on heat-generating disc hemisphere face during use, kettle can just be located by automatic pipe.3, kettle is placed on the desktop of dirt, because the kettle bottom surface that is heated is interior concave spherical surface, thus can not be dirt.4, due to the curved surface real area of sphere more much bigger than the plane of same vertical projected area (hemispherical curved surface real area is the twice of same vertical projected area), thus the heating chassis diameter of product is smaller, and the volume of product is also smaller.This is significantly for high-power external-heat electric kettle.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth technical scheme of the present invention further.
Can find out by reference to the accompanying drawings, a kind of electric kettle of the present invention, include the electric heat-generating disc of heating and the kettle body of holding liquid, distinguished: the contact surface of described electric heat-generating disc and described kettle body is Surface of Sphere; Wherein, bottom of water kettle shape is indent Surface of Sphere, and heat-generating disc end face becomes evagination Surface of Sphere, and both radians are consistent and fit tightly.
Described kettle is glass material or metal material.
Because kettle bottom surface is Surface of Sphere, after kettle is filled with water, easily tilt.The edge of described electric heat-generating disc is provided with several rigid support posts for preventing kettle from tilting; Certain gap is left in end face and the kettle bottom surface of described support column.Support column quantity can be three, also can be multiple.
In actual fabrication technique, the uniformity of the radian of the Surface of Sphere of electric heat-generating disc and kettle contact level should be given special heed to.
Claims (4)
1. an electric kettle, includes the electric heat-generating disc of heating and the kettle body of holding liquid, it is characterized in that: the contact surface of described electric heat-generating disc and described kettle body is Surface of Sphere; Wherein, bottom of water kettle shape is indent Surface of Sphere, and heat-generating disc end face becomes evagination Surface of Sphere, and both radians are consistent and fit tightly.
