Abstract
The invention discloses an upper lid and an electric rice cooker using the same. The upper lid comprises a lid body, an exothermic plate and a hollow sealing component, wherein the exothermic plate is provided with a heater and arranged on the lid body; the hollow sealing component is detachably arranged on the lid body; the sealing component comprises a mounting part and a sealing ring arranged on the mounting part; the mounting part is detachably arranged on the lid body; the sealing ring has a first sealing part and a second sealing part; the first sealing part is in clearance fit with the exothermic plate; and the second sealing part tightly adheres to the upper edge of an inner pot. Because the detachable hollow sealing component is directly arranged on the lid body, the structure of the upper lid is more conveniently cleaned when compared with the conventional undetachable structure; the structure of upper lid is simpler compared with the structure of the conventional metal inner lid; a large amount of metal material is saved; a steam port sealing ring arranged for the sealing between the metal inner lid and the exothermic plate in the prior art is not needed; and the cost is greatly reduced. At the same time, because the heat on the heater is directly radiated to rice by the exothermic plate, the thermal efficiency is improved.
Description
[technical field]
The present invention relates to electric cooker, relate in particular to improvement the superstructure of electric cooker.
[technical background]
For realizing the sealing between electric cooker loam cake and the heat liberation board, two kinds of hermetically-sealed constructions are arranged at present.
A kind of is to adopt sealing ring directly to be fixed to outer covering, not removable.After there be long-term the use in the fixed hermetically-sealed construction of this sealing ring, dirt was residual easily inner to sealing ring, was difficult for the problem of cleaning, therefore, all no longer adopted this structure on the medium-to-high grade electric cooker.
Another kind of hermetically-sealed construction is as shown in Figure 1; Sealing ring is fixed on the removable black box; This black box mainly is made up of pot sealing ring 1, metal inner cap 2 and plastic stent 3 shown in Figure 1, realizes sealing through steam port sealing ring 5 between the heat liberation board 4 of heater with cover and the metal inner cap 2.This structural metal inner cap 2 materials relatively take, and adding needs between metal inner cap 2 and the heat liberation board 4 to realize sealing through steam port sealing ring 5, and portion's article are too much, have the too high problem of cost.And the heat on the lid heater of the removable hermetically-sealed construction of this kind through heat liberation board 4 heat radiations to metal inner cap 2, again by 2 heat radiations of metal inner cap to rice, the thermal efficiency is low, does not meet energy-conservation demand now.
