Description
Technical field
The utility model relates to the structure of insulating pot, specifically is meant the electric kettle with improvement 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
