Description

Container heated by microwave oven

Technical field

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

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 type of heating do not need the traditional heating mode such as baking, steam, boil used always like that needs very long, in food in-to-in thermal energy transfer process, 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 container of micro-wave oven special use is some plastic container and ceramic apparatus to microwave, and they do not have metal ingredient, produces the electro 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 additional function.But in actual use, people use the micro-wave oven heated food, need the effect of baking on the face of these food, as freezing pizza food etc., have limited the field of application of micro-wave oven thus, can't satisfy the demand of people to this class.In addition, people find that also microwave heating of food exists irregularity in essence, especially usually occur local overheating or cold excessively when heating freezing delicatessen, and 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 packing of some frozen food and manner of packing to improve the effect of food heating, but the means of these auxiliary microwave heatings, nearly all use the non-returnable container material, can't repeated usage, the cost of packaging for foodstuff is bigger, and actual condition of service shows, their auxiliary microwave heating effect is unsatisfactory, does not improve more existing problems in the microwave heating process under many circumstances well.

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 resonant cavity and the basic law in food, propagated with the distribution of method correction microwave energy in food of microwave circuit, make micro-wave oven have the special-purpose assorted container heated by microwave oven of specific function.It includes the body that is made of plastics, and the bottom of described body is made by the plastics or the stupalith of dielectric properties, and its thickness is 0.05-0.5cm; The dielectric loss factor is 0.01-1.0, and the dielectric constant is 1.5--6.Be shaped on the layer of metal layer on the sidewall of described body; Described metal level is aluminium lamination or copper layer, and its thickness is at 0.01-0.1cm, and width is 1-5cm up and down.The bottom of described body is provided with a becket; The thickness of this becket is at 0.01-0.1cm, and ring width and is made by aluminium or copper product in 2cm.Described body disposes lid, covers to be provided with vapor opening and to be furnished with safety valve; Described covering is provided with becket, and its thickness is 0.01-0.1cm, and ring width and also has aluminium or copper product to make in 2cm.

The present invention is used in adding of micro-wave oven and pines for, both freezing pizza etc. can be made one or both sides after the micro-wave oven heating and have cured effect, can give the food of a kind of brown and crisp mouthfeel of people, 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 special-purpose heating container of micro-wave oven together with the box (or sack) of packing, put into the micro-wave oven heating then, principle according to microwave circuit, heating container utilizes the excellent conductive performance of metallic material, design one and can produce the evenly microwave field of heating, by appropriate size and structure, make these metallic materials from constituting the microwave circuit of impedance match, 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 osed top heating container 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 heats of a boiling.

Fig. 3 is the structural representation that matches on the body of the present invention and cover.

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 body made of plastic, and be shaped on a layer thickness on the sidewall of body 1 at 0.01-0.1cm, width is the metal level 2 that the aluminium lamination of 1-5cm or copper layer constitute up and down; Is that 2cm is with the interior becket that is made of aluminum or copper 3 and be provided with thickness in the bottom of body 1 in 0.01-0.1cm, ring width.The bottom 4 usefulness plastics or the stupalith of described body 1 are made, its thickness is at 0.05-0.5cm, this pottery or plastics have dielectric loss factor 0.01-1.0, the dielectric constant is 1.5-6, at the bottom of the device that this material with certain dielectric properties is made, can make it in use, the bottom produces toasting performance, thereby make food have brown and crisp mouthfeel, be particularly useful for the frozen food of pizza class is heated.This special-purpose heating container that has cured effect separately both can be made separately, also can constitute with other, and have multiple function.Body 1 of the present invention also special configuration has a seal cover cap 5, and this device lid 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 for tightening cover and body and sealing.Like this food is closed, in body 1, produces steam, and produce a lower vapour pressure, this vapour pressure can be strengthened the transmission of heat energy, produce the auxiliary heats of a boiling, the steam that produces in these heat processes can reasonably be utilized again, make it can not slattern in vain.Too high for preventing the steam pressure in the body 1, the present invention's lid 5 is provided with vapor opening and is furnished with safety valve 8.It is 0.01-0.1cm, ring width at 2cm with the interior becket of being made by aluminium or copper product 9 that described device lid 5 is provided with a thickness.
