Abstract

The utility model relates to a pot-placing table plate for an electromagnetic stove. One surface of a pot-placing table plate is provided with convex rib strips or (and) convex point-shaped objects to form the pot-placing table plate for an electromagnetic stove. The pot-placing table plate for an electromagnetic stove is compared with the existing used microcrystalline glass flat plate, the pot-placing table plate for an electromagnetic stove has the advantages of low cost, little heat loss, long service life, etc.

Description

A kind of electromagnetic oven put kitchen sink plate

The utility model relates to the platen that a kind of electromagnetic oven is placed pot.

Electromagnetic oven is a kind of fireless cooking stove, and it is by housing, puts kitchen sink plate, load coil, fairing, high-frequency inversion device, and fan cooling apparatus used and operating system is formed.The effect of putting kitchen sink plate is that to put pot heat insulation, can bear thermal shock and prevent that spilling water from entering in the electromagnetic oven.Existing electromagnetic oven put hard, heat-resisting, the low-expansion devitrified glass porcelain that kitchen sink plate is a plane, through the plane microcrystal glass plate of machining, stick with glue agent be adhesive in the electromagnetic oven housing on cover.The microcrystal glass plate complex manufacturing on plane costs an arm and a leg, and most platen all is import.How reducing heat utilization and service life and minimizing import or import substitution that electromagnetic oven is put the cost of kitchen sink plate and can be improved electromagnetic oven, is many scientific research personnel's research topic.

The purpose of this utility model is for solving above-mentioned existing problems, provide a kind of cost low, convenient formation, and the electromagnetic oven that heat utilization efficiency is high is put kitchen sink plate.

Electromagnetic oven is that electric energy magnetic and irony pot produce eddy current heat, and the eddy current thermal source is mainly in the bottom of pot body, and the heat conduction of pot body eddy-current heating part is being born on the platen plane of pot body lower curtate contact.Design in view of the above on a kind of one side surface of placing pot by outstanding rib or (with) outstanding point-like thing constitute put kitchen sink plate.Put the outstanding rib of kitchen sink plate or (with) outstanding point-like thing can adopt devitrified glass, refractory ceramics, no magnetic metal and chemical polymerization thing.Outstanding rib or (with) outstanding point-like thing supporting the pot body and bearing the heat conduction of a face, reduced the heating surface area of putting kitchen sink plate, increased that the air of bottom of pot body heating part is heat insulation to be conducted to the pot body portion of not being heated with air heat, reach economical with materials and production cost, strengthen the utilization rate of service life and raising heat.Put the outstanding rib in kitchen sink plate and its surface or (with) outstanding point-like thing can be identical materials, through the machining moulding, perhaps injection-compression molding, perhaps sinter molding: also can with outstanding rib or (with) outstanding point-like thing is embedded on the substrate of engineering plastics material: can also with outstanding rib or (with) point-like thing pressure injection is on the substrate of engineering plastics material.The part of putting kitchen sink plate placement pot can be the concavity spherical, also can be plate, to be fit to the needs that Chinese cooking is nursed one's health the western-style food dish with the cooking custom and the pan of arc-shaped pot.The most economical kitchen sink plate of putting is that platen and electromagnetic oven case top lid are shaped to one with high-temperature resistance plastice, case top lid put pot part (being platen) have outstanding rib or (with) outstanding point-like thing.

Electromagnetic oven described in the utility model is put kitchen sink plate, has both reduced the production cost of electromagnetic oven, has improved the service efficiency and the life-span of electromagnetic oven again.

Fig. 1 is the structural representation of embodiment 1;

Fig. 2 is the cut-away view of embodiment 2, embodiment 3;

Fig. 3 is the cut-away view of embodiment 4.

Embodiment 1, puts the muscle of giving prominence to slice on the pot one side surface at devitrified glass plane platen, and the layout of rib is benchmark with the platen center, with 15 muscle, is evenly distributed in platen surface.Muscle is long to be 20mm, and wide is 2mm, and projecting height is 2mm, and putting kitchen sink plate gross thickness is 5mm.This platen press injector and mould injection-compression molding also can be on former crystallite glass substrate surfaces, through the machining moulding.1 is the irony pot among the figure, the 2nd, and the rib of giving prominence to, the 3rd, put kitchen sink plate, the 4th, case top lid, the 5th, housing chassis.

Embodiment 2, and devitrified glass is replaced with thermostability engineering plastic substrate 7, inlay the point-like thing made from crystallite 6 on engineering plastics substrate 7.Engineering plastics substrate 7 is thick to be 3mm, and the point-like thing 6 that devitrified glass is made is

Shape, length overall are 5mm, and the height of outstanding hemisphere face part is 2mm, and the hemisphere face maximum gauge is 4mm, and minimum diameter is the some face, Shape bottom (embedded part) length is 3-4mm, and the 2-3mm that makes tapering is square, is provided with the square hole of 2-3mm during substrate 7 moulding, with 504 adhesive handles

In the square hole that the devitrified glass point-like thing 6 of shape is embedded on the substrate 7, three point-like things are a row to quantity for well with 18, distribute uniformly.

Embodiment 3, devitrified glass or there is not the metal point-like thing 6 of magnetic, are placed in the die cavity of mould, with press injector 6 pressure injections of engineering plastics and point-like thing become to put kitchen sink plate 7.

Embodiment 4, with plastic pressure injection machine and mould, the rib 2 that thermostability engineering plastic and devitrified glass or refractory ceramics are made or (with) point-like thing 6, be placed on pressure injection in the die cavity of mould, the rib 2 that devitrified glass or refractory ceramics are made during injection-compression molding or (with) point-like thing 6, the height of outstanding case top lid 4 should be 2mm, case top lid 4 is thick to be 3mm, gross thickness is 5mm, and the rib 2 of devitrified glass or refractory ceramics system or the shape and the layout of point-like thing 6 can be decided according to the design needs.

Claims
