Abstract

The utility model discloses an electric pot which comprises a kettle lid 1, a kettle body 2 whose middle bottom is concave-shaped, a convex-shaped heating body 3 whose convex part fits with the concave part of the kettle body 2, and a kettle holder 4 used for supporting the heating body 3. The utility model enlarges the contact area between the heating body 3 and the kettle body 2, and accelerates the absorption and utilization of heat. The utility model has the advantages of high efficiency, safety and durability, which is suitable for boiling water by households and hotels.

Description

Electric kettle

The utility model relates to a kind of electric kettle.

The electric kettle that uses on the market, mostly form by kettle body and heater element, heater element generally is placed in kettle body inside or is connected the external bottom surface of kettle, it as the disclosed application number of Patent Office of the People's Republic of China 93245164 low-voltage electroheating kettle, this electric kettle is made up of kettle body and base, lead and heating, heating is attached to the outer bottom of kettle body, and base support kettle body and supply socket are installed on the base.This kettle is because heating only simply is attached to the external bottom surface of kettle, and heating surface is narrow, and heat absorption is slow, and heat utilization ratio is low.

The purpose of this utility model provides and is subjected to the electric kettle that thermocontact area is big, heat absorption is fast, heat utilization ratio is high between a kind of kettle body and the heater element.

For achieving the above object, the utility model comprises pot lid, kettle body, heater, kettle seat, heater is made up of heater element and the housing that wraps in the heater element outside, wherein the kettle body is placed on the heater that is subjected to kettle seat support, it is characterized in that: upwards caving in the middle of the kettle body bottom is the inversion concavity along shaft section, described heater is convex along shaft section, and described concavity is a bit larger tham convex and matches.

The described concavity of kettle body is trapezoidal along shaft section, and described heater is trapezoidal along shaft section.

The described concavity of kettle body is along the shaft section semicircular in shape, and described heater is along the shaft section semicircular in shape.

Adopted after the said structure; the concavity of heater side, last end face and kettle body partly matches; contact-making surface enlarges greatly; quickened the transmission of heat, simultaneously heater is included in kettle body concavity partial interior, the not only slow radiation loss of heat; improved heat utilization ratio; and the liquid of kettle body inside can not overflowed on the heater when boiling, and protect heater element, prolonged the service life of heater.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the schematic diagram of first embodiment of the present utility model.

Fig. 2 is the schematic diagram of another embodiment of the present utility model.

Electric kettle as shown in Figure 1, comprise pot lid 1, kettle body 2, heater 3 and kettle seat 4, be the inversion concavity in the middle of kettle body 2 bottoms, the concavity part is trapezoidal along shaft section, heater 3 is trapezoidal along shaft section, just partly match with kettle body 2 concavities, heater 3 is placed on the kettle seat 4, the last end face shape of the bottom surface shape of heater and kettle seat consistent and less than or be slightly smaller than the last end face of kettle seat.

Be the schematic diagram of another embodiment of the present utility model as shown in Figure 2, wherein kettle body 2 central bottom are the inversion concavity, and the concavity part is along the shaft section semicircular in shape, and heater 3 is protruding semicircle along shaft section, partly matches with kettle body 2 concavities.

The concavity part can also adopt other shape with the contact-making surface of heater in the middle of this electric kettle kettle body bottom, as cylindrical or taper etc., all drops within the protection domain of the present utility model.
