Abstract
The invention discloses induction furnace, it is used to solve the difficulty in cooking using non-flat cooking container, especially in the case where the projecting region in the centre of the plane of cooking container (plane).Precisely, which provides a kind of new induction furnace structure, the heating surface with 2 different heights.Heat effectively can be directed to non-flat cooking container by this new construction of the induction furnace.
Description
Technical field
The present invention relates to mechanical engineerings, more particularly to induction furnace.
Background technique
It is very popular to roast dish, especially client oneself cooks and burn barbi or so-called Bar B Que shape
Formula.Therefore, such dining room is usually that customer provides stove and grill or baking tray.Further, since such
Dining room is usually located at air-conditioned interior, it is therefore necessary to use aphlogistic stove, such as electric furnace, which passes through heating position
Coil in the groove of thermal insulating disc generates and increases heat.Such electric furnace is cheap, therefore is widely used.
However, non-combustible itself will lead to adverse effect when the coil exposed of the heat in stove is when combustible material.If material quilt
It lights, may result in and smolder.Flame may also can be diffused into other materials, such as paper or cloth pad.
The specific characteristic of induction furnace is only to conduct heat to certain form of cooking container, such as be formed from steel or by certain
Cooking container made of the stainless steel of type.Therefore, if cooking container does not have electromagnetic property, it will not be on induction furnace
It is heated.For example, the cooking container made of aluminium, glass or ceramics.Different from normal stove, induction furnace is directly suitably being cooked
It prepares food the bottom conductive heat of container, without making heat pass through other media.Therefore it is suitble to dining room use indoors.
However, widely used induction furnace has flat cooktop surface currently on the market, therefore it is only applicable to flat culinary art
Container.If the bottom of cooking container or pot is not flat or horizontal, such as certain parts of cooking container bottom do not connect
Cooktop surface is touched, then the electromagnetic induction process for generating heat will not work.Therefore, usually there is the induction furnace of flat cooktop surface not
It can be used together with the cooking container of uneven or non-aqueous flat bottoms, or cannot be from the different culinary art sides of combination in a vessel
The cooking container of method is used together, such as the cooking container with the part for barbecue and the part for boiling/heating soup.
Therefore, it is necessary to manufacture a kind of induction furnace of heat that can generate different stage, a region with barbecue, another, which has, adds
The region of hot soup.In order to barbecue simultaneously and heating soup, stove may also be needed with the cooktop surface positioned at different height.Cause
This, commercially available induction furnace cannot be used for this purpose.
According to Chinese practical new model CN 20366139, title of the invention is double lead and bicyclic coil panel, it is solved
The shortcomings that have released widely used include the common induction furnace of single wire.When heat is incuded, heat will be in lead institute
The entire cooktop surface diffusion of expansion.Although for relatively small cooking container, it is only necessary to which a small amount of heat, induction furnace is still
It radiates in whole region, therefore wastes energy.On the other hand, if the area of lead induction is small, heat is only introduced into one
Fritter area.Therefore, it will be time-consuming for generating more suitable heat for large-scale cooking container.The purpose of the utility model is to solve
Aforementioned problem；Mainly waste energy and cooking time are solved by providing adjustable heating region according to personal preference
The problem of.This and is connect them to complete with controlable electric current by having double lead and bicyclic coil in the same plane
's.When needing small induction region, switch can be gone into selected internal circuit, such heat will be induced to inner loop
Shape coil.When needing biggish induction region, switch can be gone into the position that inside and outside circuit is switched on, it is hot in this way
Amount will be incuded simultaneously to two loop coils.Obviously, which is suitable for flat cooking container, but is not suitable for non-flat
Bottom cooking container.
On April 15th, 2014 announce U.S. Patent number US8695488 also set forth sell extensively in the market in panel
In there is the problem of traditional induction furnace of one or more heating surfaces.Problem is that food once also only can be by a surface
Heating, and the stove of these types generates heat by the heat transfer of electrothermal tube or heat radiation.Therefore, pan or heating plate
With lower heating effect, lower power effect and longer preheating time.This is because contact heat transfer, tradition are cooked a meal
The pan or heating plate of tool are easily deformed, and lead to lower heating speed, and cooking food is uneven.Therefore, of the invention
Solved these problems by providing multi-function electromagnetic rang, disadvantages mentioned above eliminated by design structure and circuit, with generate with
Lower effect.Food can heat simultaneously from top and bottom, and can heat pan on both surfaces simultaneously.Heating system
System include three electromagnetic coils: wherein first coil be arranged in main body, second and tertiary coil be arranged in another main body,
So as to by using switch simultaneously by two main bodys generation heats, the switch property of can choose by second or tertiary coil
In one be connected to first coil.Under the second connection status, three electromagnetic coils are connected in series.In addition, the multi-functional electricity
Magnetic stove is invented as folding (folding heating surface).Therefore, food can be heated from top and bottom, comparably by heat
The two sides of food are distributed to, to reduce time and the energy of culinary art.In addition, if user wants to reduce the specific master of electromagnetic stove
Heat grade in body, then can close the power supply of the second coil.However, the invention (multi-function electromagnetic rang) still with it is non-flat
Cooking container is incompatible.
Summary of the invention
Induction furnace of the invention is to solve the problems, such as above-mentioned non-flat cooking container, the especially middle part of cooking container
Higher than the cooking container of that type of rest part.This induction furnace is designed as the induction furnace for the cooktop surface structure for having new, should
Cooktop surface includes two heating surfaces for being located at different height, it is ensured that heat is fully introduced into non-flat cooking container.
