Description
Technical field
The invention belongs to the electric kettle technical field, is a kind of electric kettle that includes the improvement syndeton of kettle body upper casing, kettle body lower casing, electric heating base plate, electric connector.
Background technology
At Chinese patent, application number 95192410.9, name is called in the heating vessel application for a patent for invention prospectus and discloses a kind of heating vessel, and its structure includes the molded main body of polypropylene 4, and it has wall 6 and handle 8; The bottom 10 of container 2 is level and smooth; Be welded on the heating 12 on the bottom 10; Thermally-responsive controls 14; Bottom 34.The inner radial wall 24 of the bottom 22 of plastic wall 6 forms a step 26, and it is used to settle the silicone rubber sealing ring 28 of a square-section.Bottom 22 radial outer wall 30 form a chimb 32, and the outer rim 18 of groove 16 can be curled on boss limit 32.The periphery of bottom 10 has groove 16.During assembling, at first, sealing ring 28 is spread on the bottom 22 of wall 6, and be close to step 26 and settle, on the inner and outer wall of bottom 22, apply lubricant then, and the groove 16 of bottom 10 pushed away on end 22, abut against up to the bottom 36 of groove 16 on the lower limb 38 of wall 6, step 26 prevents that sealing ring 28 is pushed in the container, after the bottom is in place, the outer rim 18 of groove 16 is curled, on boss limit 32 so that the bottom 22 of wall is clamped between outer rim 18 and the sealing ring 28, this applies a pressure on the thickness of wall 6, thereby reduces thermal creep as far as possible.The heating vessel of this structure exists following problem in processing and manufacturing and fit on:
1, the wall 6 of main body 4 at first is assembled together with the bottom 10 of container 2, needs to adopt process for pressing, and the groove 16 of the periphery of bottom 10 clamped is pressed on the wall 6 of main body 4 the assembly technology complexity.
2, become one structure when main body 4 and bottom 10, because main body 4 is a circular configuration often with bottom 10, both connect for tight fit, can't rotate adjustment relatively.And thermally-responsive controls 14 is mounted on the bottom 10, and 34 of bottoms can only be fixed on the bottom 10, in case main body 4 and bottom 10 secure bond, bottom 34 is just also fixing thereupon with the binding site of main body 4.
3, be communicated with air-breather up and down owing to needing in the handle, the lower end of handle need be installed between the wall 6 and bottom 34 of main body 4, steam can be fed in the bottom 34 from container 2, so need to consider the installation of handle 8.Main body 4 synthesizes in the process of one with bottom 10, be easy to cause rotary shifted, in case dislocation, bottom 34 is fixed on inevitable dislocation thereupon on the bottom 10, handle installation site on the handle installation site of reserving on the bottom 34 and the wall 6 of main body 4 just produces dislocation, and handle 8 just can't installation in position.
4, because its assembling process must be to assemble main body 4 and bottom 10 earlier, thermally-responsive controls 14 is installed on bottom 10 again, bottom 34 is installed at last.In case main body 4 and bottom 10 assembling dislocation, both all can scrap, and this will cause a very big loss.
5, finish the electric property test that just can carry out product behind above-mentioned these assembly processes, in case the electric property test failure, main body 4 is scrapped owing to taking apart with bottom 10, causes damage equally.
Summary of the invention
The purpose of this invention is to provide a kind of being convenient to and make, assemble the electric kettle of improvement syndeton easy to adjust.
For realizing purpose of the present invention, the electric kettle of described improvement syndeton, comprise kettle body upper casing, the kettle body lower casing that can mutually combine, be arranged on the electric heating base plate between kettle body upper casing and the kettle body lower casing, be installed in the electric connector on the electric heating base plate, described upper casing bottom margin is provided with hanging hole, kettle body lower casing is provided with the hook that can collude in the hanging hole, the electric heating base plate is fixed on the kettle body lower casing, its periphery is provided with sealing ring, and sealing ring is clamped in when kettle body upper casing combines with kettle body lower casing between the lower inside wall of the periphery of electric heating base plate and kettle body upper casing.
Owing to adopted hanging hole, hook to make kettle body upper casing, the combination of kettle body lower casing, the electric heating base plate is fixed on the kettle body lower casing, its periphery is provided with sealing ring, this structure causes wanting earlier the electric heating base plate to be fixed on the kettle body lower casing when assembling, after next process can guarantee kettle body upper casing and kettle body lower casing combines, handle can be disposable or be dropped on both binding sites by adjustment.Because do not have secure bond between kettle body upper casing and the electric heating base plate, just in case kettle body lower casing can't with accurate combination of kettle body upper casing, can be rotated kettle body lower casing operation, until both accurate combinations, in the process that is rotated the operation of kettle body lower casing, the electric heating base plate rotates thereupon.The present invention can make assembly process simple, installs and adjusts easily, can not cause the electric heating base plate to be scrapped with kettle body upper casing because of the assembling dislocation.After the electric heating base plate is fixed on the kettle body lower casing, be convenient to carry out preliminary security appliance test, pinpoint the problems early.In case pinpoint the problems, be convenient to dismounting and change electric heating base plate, be unlikely because of itself and combining of kettle body upper casing make kettle body upper casing and scrap thereupon.
