Abstract

A microwave cooker is composed of main body made of plastics and with a metal layer on its side wall, and a cover with steam hole, a safety valve and a metal ring. The mentioned main body has a bottom which is made up of dielectric plastics of ceramics and has a metal ring. Its advantages are simple structure, high effect and high safety.

Description

The microwave pot

Technical field

The present invention relates to be a kind of micro-wave oven that is matched in specially to the device that food heats, belong to food heating corollary apparatus.

Background technology

As everyone knows, microwave heating of food has become a kind of very general method, no matter be used in family cooking or in the catering trade, this microwave heating equipment is referred to as micro-wave oven.Microwave be by the electromagnetic wave transferring heat energy in food, because electromagnetic wave can be at the food internal communication, so microwave also inside of heated food in the heated food surface, since this mode of heating do not need the traditional heating mode such as baking, steam, boil used always like that needs very long, in the thermal energy transfer process of food inside, the speed that its heats is very fast.Because this quick and characteristics existence easily of micro-wave oven, it is bringing into play more and more important effect in current daily life; In house and catering industry, micro-wave oven has become a kind of indispensable heating tool.At present, the pan of micro-wave oven special use is some plastic containers and ceramic apparatus to microwave, and they do not have metal ingredient, produces the electric spark phenomenon to avoid using in micro-wave oven.Their use just plays the function of splendid attire food nothing but, and does not have other any miscellaneous function.In actual use, it is found that microwave heating of food exists inhomogeneities in essence, hot-spot or cold excessively especially usually occurs when heating freezing delicatessen, part food Jiao stick with paste and the still ice-cold phenomenon of another part.Although food production merchant who has and packaging for foodstuff manufacturer have developed the packaging material of some frozen food and manner of packing to improve the effect of food heating, but the means of these auxiliary heating using microwaves, nearly all use the non-returnable container material, can't reuse, the cost of packaging for foodstuff is bigger, and actual operating position shows, their auxiliary heating using microwave effect is unsatisfactory, does not improve more existing problems in the microwave heating process under many circumstances well.In addition, these micro-wave oven specialized package containers do not have heated food are had cured effect, for need having the frozen food of brown and crisp mouthfeel powerless on its surface as the pizza class.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of can be according to microwave in resonator and the basic law in food, propagated with the distribution of method correction microwave energy in food of microwave circuit, make the special-purpose assorted microwave pot of micro-wave oven that all obtains suitable heat energy everywhere.It includes the pot body that is made of plastics, and is shaped on the layer of metal layer on the sidewall of pot body.Described metal level is aluminium lamination or copper layer, and its thickness is 0.01---0.1cm, and width is 1 up and down---5cm.The bottom of a pan of described pot body is made by the plastics or the ceramic material of dielectric properties, and its thickness is 0.05---0.5cm, and the dielectric loss factor 0.01---1.0, the dielectric constant is 1.5---6.The bottom of described pot body is provided with a becket; The thickness of this becket is 0.01---and 0.1cm, ring width and is made by aluminium or copper product in 2cm.Described pot body disposes pot cover, and pot cover is provided with vapor opening and is furnished with safety valve; Described pot cover is provided with becket, and its thickness is 0.01---and 0.1cm, ring width and also has aluminium or copper product to make in 2cm.

The present invention is used in adding of micro-wave oven to pine for, and heat energy more is evenly distributed in the food, thereby obtains delicious, good to eat food; Be food on occupation mode, particularly freezing delicatessen is placed in the microwave pot together with the box (or sack) of packing, put into the micro-wave oven heating then, principle according to microwave circuit, the microwave pot utilizes the excellent conductive performance of metal material, design one and can produce the evenly microwave field of heating, by appropriate size and structure, make these metal materials from constituting the microwave circuit of impedance matching, and then the electromagnetic field with even heating is strengthened, and uneven electromagnetic field is weakened.Can improve the even Fast Heating of food effectively.The present invention has also utilized the microwave pot of sealing in addition, produces the back at steam and forms a lower vapour pressure, and this vapour pressure can be strengthened the transmission of heat energy, produces the auxiliary thermal effect that adds of a boiling.

The specific embodiment

The present invention will be described in detail below in conjunction with accompanying drawing: shown in Figure 1, the present invention includes a pot body made of plastic, be shaped on a layer thickness 0.01 on the sidewall of pot body 1---0.1cm, width the is 1 up and down---aluminium lamination of 5cm or metal level 2 that the copper layer constitutes; And being provided with thickness 0.01 in the bottom of pot body 1---0.1cm, ring width are that 2cm is with the interior becket that is made of aluminum or copper 3.The bottom of a pan 4 usefulness plastics or the ceramic material of described pot body 1 are made, its thickness is 0.05---0.5cm, this ceramic material or plastics have the dielectric loss factor 0.01---and 1.0, the dielectric constant is 1.5---6, this bottom has the material of certain dielectric properties and makes, can make its bottom produce toasting performance, thereby make food have brown and crisp mouthfeel, it is particularly useful for the heating to the frozen food of pizza class.Pot body 1 of the present invention also special configuration has a sealed pot cover 5, and this pot cover 5 is made of plastics, and it links to each other with pot body 1 with hinge 6 on one side; Another side is provided with snap close 7 and is used to lock pot cover and pot body and sealing.Like this food is closed, in pot body 1, produces steam, and produce a lower vapour pressure, this vapour pressure can be strengthened the transmission of heat energy, produce the auxiliary thermal effect that adds of a boiling, the steam that produces in these heating processes can reasonably be utilized again, make it can not slattern in vain.Too high for preventing the steam pressure in pot body 1, the present invention's pot cover 5 is provided with vapor opening and is furnished with safety valve 8.It is 0.01 that described pot cover 5 is provided with a thickness---0.1cm, ring width at 2cm with the interior becket of making by aluminium or copper product 9.
