Description
Technical field
The utility model relates to the structure of insulating pot, specifically is meant the improved electric kettle of a kind of hermetically-sealed construction.
Background technology
Insulating pot is one of small household appliances of using always, is used for water is heated, and can be used as the container of water simultaneously again, has characteristics easy to use.Be provided with electric heater unit at the bottom of the kettle of insulating pot, early, this heater is an electrothermal tube, stretch in the container from container bottom is convex, so that the water in the container is heated,, get rusty because of being subjected to corroding easily owing to be exposed to fully in the water as the electrothermal tube of heat generating components, damage at last and can't use, and influence health.
Therefore, it is plane electric heater unit that designer has in the industry designed heating surface, and this electric kettle has two kinds of basic structures.A kind of is the canister that is formed in one of container of dress water, electric heater unit is located at its below, bottom, during heating, whole canister all can be heated, must outside canister, cover a plastic casing again, safe in utilization to guarantee, and between plastic casing and canister, thermal insulation layer must be arranged, thereby production technology bothers, cost is higher.Another kind is the bottom that electric heater unit is lifted on plastic containers, and its plane heating surface forms the bottom of heating container, directly contacts with water it is heated.
For above-mentioned second kind of structure, the hermetically-sealed construction between heater and the kettle body madial wall is the key factor of insulating pot performance.Existing hermetically-sealed construction is: the madial wall appropriate location at the kettle body is provided with a bulge loop, between heater periphery end face and this bulge loop bottom surface, establish a sealing ring, and on axially, a compressible spring assembly being set, this spring assembly applies one in the axial direction makes the sealing ring compression to reach the active force of sealing from bottom to top.Spring may occur and be compressed by water gravity in process to boil water, the situation of leaking does not tightly appear in sealing, and assembly difficulty is big, and cost is higher.
Another kind of hermetically-sealed construction is: sealing ring is between kettle body madial wall and heater outer peripheral face, the outer peripheral face of sealing ring generates the rib of two-layer bulge loop shape, during assembling, utilize this rib and kettle body madial wall inconsistent and produce the effect that flange in the same way reaches sealing, be provided with some ribs longitudinally at this kettle body madial wall, the sealing circle is between heater and each rib bottom face, and upwards hold out against by support ring self-heating apparatus below, make it fixing in the axial direction, and this support ring is sticked on the kettle body madial wall and reach the purpose of support fixation.This kind hermetically-sealed construction is prone to the rib flange direction that seals on the sealing ring and differs in assembling process, form waveform on circumference, cause leaking, and its assembly difficulty is also bigger.
The utility model content
The utility model provides a kind of hermetically-sealed construction improved electric kettle, and the hermetically-sealed construction that its main purpose is to overcome existing electric kettle is because of designing the unreasonable assembling inconvenience that causes, easy shortcoming such as leak.
The utility model adopts following technical scheme: the improved electric kettle of a kind of hermetically-sealed construction, comprise Hu Bi, the heating plate of annular and be located at the heater of heating plate below, this heating plate is located at the bottom position in the kettle wall, its end face and Hu Bi surround the space that is filled with water together jointly, described heating plate bottom surface periphery is connected with a bakelite ring, be folded with a silica gel sealing ring between this electronics ring and this heating plate, the outer peripheral face of this silica gel sealing ring and described kettle wall medial surface are conflicted and are formed sealing surface; Be connected by grab, draw-in groove between described bakelite ring outer peripheral face and the described kettle wall; The locking of the bottom face of described Hu Bi has a base cover, the end face of this base cover to be provided with to be connected to the fin of described bakelite ring below.
The improved electric kettle of aforementioned a kind of hermetically-sealed construction, the nearly peripheral position of its heating plate raises up, and forms a bulge loop, and the first half of described bakelite ring is embedded in this bulge loop from the bottom to top; The external diameter of the Lower Half of described bakelite ring is greater than the external diameter of its first half, form a cascaded surface between the two, the cross section of described silica gel sealing ring comprises a lateral part and a longitudinal component, this lateral part is located between the cascaded surface of the periphery in the heating plate bulge loop outside and described bakelite ring, and the outer peripheral face of its longitudinal component forms described sealing surface.
The lateral wall of the bulge loop of described heating plate is provided with inwardly protruded positioning convex portion, and described bakelite ring first half lateral surface is provided with the boss that is connected in described positioning convex portion below, and this boss is provided with the breach that passes through from bottom to top for described positioning convex portion.
The nearly bottom position of described kettle wall medial surface is provided with down a cascaded surface, and outer half one of described silica gel sealing ring lateral part is connected to the below of this cascaded surface.
The bottom surface of described silica gel sealing ring lateral part is provided with the annular protrusion to lower convexity, and this annular protrusion is embedded on the cascaded surface of described bakelite ring.
The sealing surface of described silica gel sealing ring is provided with the ring rib with described kettle wall medial surface butt.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, during assembling, earlier on the cascaded surface with the sheathed from top to bottom bakelite ring of silica gel sealing ring, the first half with the bakelite ring is assemblied in the bulge loop of heating plate from the bottom to top again, silica gel sealing ring is located between heating plate and the bakelite ring, then again the bakelite ring is assemblied in from the bottom to top the bottom in the kettle wall, this shows, its assembling is simple, realizes easily; Two, silica gel sealing ring is heated dish and after the bakelite ring was fixedly clamped, ability was assembled to the bakelite ring in the kettle wall, thereby this silica gel sealing ring can not produce the phenomenon of flange, fold, seals more stable and reliable.
