Description

A kind of micro-wave oven

Technical field

The present invention relates to a kind of micro-wave ovens, more specifically, are related to a kind of facilitate and pick and place food and can be evenly heated food The micro-wave oven of object.

Background technique

Micro-wave oven is the cooking apparatus for absorbing microwave energy in microwave field using food and making conducting self-heating, in micro-wave oven The microwave that microwave generator generates sets up microwave electric field in microwave cavity, and takes certain measure that this microwave electric field is made to exist It is evenly distributed as much as possible in furnace chamber, food is put into the microwave electric field, its cooking time and microwave electric field are controlled by control centre Intensity heats food to realize.

Since microwave is in heating intracavity reflecting, cause in the heating temperature of heating chamber different location and uneven, household is micro- Wave furnace usually by the way of rotary heating food, realizes being evenly heated for food.But due to the angle of microwave magnetron transmitting It spends and fixes, still result in the heating of food upper and lower level unevenly, upper food overheat, and lower layer's food cannot obtain sufficiently adding Heat, additionally due to the greatest differences between the dielectric property of food and the dielectric property of air, the edge heating of food is more serious. Subsequent improved micro-wave oven realizes the homogenous diffusion of microwave using rotation microwave stirrer, alleviates heating to a certain extent not Uniform problem, but still can not realize the uniformly heated problem of top and the bottom.And existing micro-wave oven is to different foods It is heated, microwave is distributed the influence that will receive food, causes microwave in region clustering, leads to the excessive food heating in the region Food is caused to be destroyed.Explosion, kindling occur for the excessively high food that also results in of temperature in some cases, further bring to daily life Harm.

At the end of common microwave oven cooking, the temperature in furnace chamber is higher, or even under forced air convection model, chamber Temperature can reach 250 DEG C or so, and user can not directly fetch hot ripe food in furnace chamber with hand, and also be inconvenient to make The disk bowl for holding food is clamped with clip, this brings very big inconvenience to user, and for this situation, some manufacturers make A little improvement, as disclosed a kind of conveyor type micro-wave oven in Chinese patent literature CN200943889Y, it is characterized in that: including Pedestal, installs the first roller and the second roller on pedestal, and conveyer belt is installed in the periphery of the first roller and the second roller, the first shield of installation on pedestal Plate and the second backplate, the first backplate and the second backplate are located at the two sides of conveyer belt, mounting bracket on pedestal, install on bracket Lifting device installs cover on lifting device, installs shell on the second backplate, installation magnetron and microwave oven supply power in shell, Magnetron is connect by conducting wire with microwave oven supply power.The conveyor type micro-wave oven of this structure can be at the end of culinary art, automatically Food delivery is come out, there is certain convenience, it is still, bulky, it takes up space more, cost of manufacture is high, It is not suitable for family's use.

Using the micro-wave oven of cube furnace chamber (heating chamber), since there is also 8 useless energy storage dead angles in furnace chamber, both The utilization rate for extending heating time, reducing energy again；Thus, conventional microwave oven, which exists, picks and places food inconvenience, food The defects of uneven heating is even, and microwave energy utilization rate is low, high production cost.

Therefore it is uneven to solve domestic microwave stove heating, food inconvenience and the low problem of efficiency are picked and placed, to the modern life It is of great significance to.

Summary of the invention
