Description

Microwave cooking utensil of even heating

Technical Field

The utility model relates to a culinary art domestic appliance field especially relates to an even heating's microwave cooking utensil.

Background

The microwave heating cooking device is used for heating and cooking food by using microwaves with certain wavelengths. However, the food material cannot be uniformly heated due to the wavelength characteristics of the microwaves.

In the existing microwave cooking apparatus, as disclosed in the document with the patent application number of 200510013941.X, a stirring fan is provided in a cooking cavity to scatter microwaves so as to improve uniform heating performance. However, the solution that the output shaft of the motor arranged outside the cooking cavity extends into the cooking cavity to drive the stirring fan for stirring has a limited effect.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving above-mentioned problem at least partially, provide a microwave cooking utensil that heating effect is good, this microwave cooking utensil can improve the microwave distribution homogeneity of culinary art intracavity, and then improves the effect of culinary art.

The utility model adopts the technical scheme as follows:

the utility model provides an even heating's microwave cooking utensil, includes the pot body and lid, be equipped with interior pot and the microwave generating device of metal system on the pot body, interior pot is formed with the culinary art chamber, microwave generating device feeds in the microwave to the culinary art intracavity from the bottom of interior pot, be equipped with the inner cup of metal system on the lid, one side that the inner cup is close to the culinary art chamber is equipped with the arc arch that is used for to culinary art intracavity reflection microwave.

Because the microwave is from the regional upward transmission that interior pot bottom is close to the center, the microwave mainly concentrates on the middle part region in culinary art chamber, sets up the arc arch through the one side that is close to the culinary art chamber at the inner cover for the microwave of interior pot bottom upward transmission takes place more, the reflection of wider angle on the bellied arcwall face of arc, thereby sends out the microwave and scatters in order to increase the regional microwave density in culinary art chamber border, improves culinary art intracavity microwave distribution homogeneity.

Further, the diameter of the arc-shaped protrusion becomes larger as the distance from the center of the inner cap increases.

Under the condition that the height of the arc-shaped bulge is fixed, the smaller the diameter of the arc-shaped bulge is, the larger the curvature of the arc-shaped surface of the arc-shaped bulge is, so that the larger the included angle between incident microwave and reflected microwave is. Referring to fig. 3, the microwave reflection diagram with an arrow shows that the diameter of the arc-shaped protrusion on the inner lid near the center is relatively small, so that the included angle between the incident microwave and the reflected microwave is increased, and the microwave density in the peripheral area can be increased better. Similarly, the arc-shaped bulge of the peripheral area enables the reflected microwaves to be concentrated in the area, and the microwave density of the peripheral area is further increased. Therefore, the microwave in the cooking cavity is more uniform, and a better cooking effect is realized.

Furthermore, the ratio of the diameter to the height of the arc-shaped protrusion ranges from 1 to 70.

The ratio of the diameter to the height of the arc-shaped bulge is too large, so that the curvature of an arc-shaped surface of the arc-shaped bulge is too small, the angle between the microwave incident angle and the reflection angle is too small, and the uniformity of microwaves is difficult to improve; the ratio of the diameter to the height of the arc-shaped bulge is too small, so that the curvature of the arc-shaped surface of the arc-shaped bulge is too large, and the processing difficulty of the arc-shaped bulge is increased. Through inciting somebody to action protruding diameter of arc and height ratio limit for 1 ~ 70, can enough obtain better processing manufacturability, can guarantee again that the microwave after the protruding reflection of arc can be in culinary art intracavity evenly distributed.

Furthermore, the diameter range of the arc-shaped bulge is 5-35 mm.

The diameter of the arc-shaped bulge is too small, so that the processing difficulty of the arc-shaped bulge is too large; the diameter of the arc-shaped protrusions is too large, so that the number of the arc-shaped protrusions is small under the condition that the diameter of the inner cover is certain, and the improvement on the uniformity of microwaves is limited. The diameter range of the arc-shaped bulge is limited to be 5-35 mm, so that good processing and manufacturing performance can be obtained, and the microwave reflected by the arc-shaped bulge can be uniformly distributed in the cooking cavity.

Further, the arc-shaped surface of the arc-shaped protrusion is a paraboloid or a spherical surface.

The arc-shaped surface of the arc-shaped protrusion is set to be a paraboloid or a spherical surface, so that the microwave reflecting effect at each position on the arc-shaped surface can be better and uniform.

Furthermore, the inner cover is also provided with a steam exhaust hole, and the steam exhaust hole is arranged on the arc-shaped surface of the arc-shaped bulge.

The punching press sets up on the lid during the steam vent, can lead to steam vent region atress to warp, influence the outward appearance, through setting up the steam vent on the bellied arcwall face of arc for simultaneous processing steam vent when stamping forming arc is protruding, the deformation that probably produces when processing steam vent changes into the arcwall face into guarantees that the inner cup is holistic pleasing to the eye.

Furthermore, the diameter of the arc-shaped bulge provided with the steam exhaust hole is larger than the diameters of other arc-shaped bulges.

Because the arc-shaped convex surface area part provided with the steam outlet is occupied by the steam outlet, in order to ensure the reflection efficiency of the arc-shaped convex part, the diameter of the arc-shaped convex part of the steam outlet is set to be larger than the diameters of other arc-shaped convex parts.

Further, still be equipped with the metal inner shell of middle part indent on the lid, the inner cup is installed the indent region of inner shell.

So, can realize the culinary art chamber maximize as far as, promote the volume in culinary art chamber to satisfy the culinary art demand that the different volume sizes of user eat the material.

Furthermore, a sealing ring is arranged on the periphery of the inner cover, and the inner cover is pressed on the inner shell.

So, avoid cooking the area that oil smoke, steam etc. in-process got into between inner cup and the inner shell, reduce the clean area of user's needs.

Furthermore, a lower concave part formed by stamping is arranged in the middle of the inner cover, and the arc-shaped protrusion is arranged on the lower concave surface.

During cooking, the temperature in the cooking cavity is high, so that the inner cover is deformed by heating. The lower concave part formed by stamping is arranged in the middle of the inner cover, so that the overall strength of the inner cover can be improved, and the inner cover is prevented from deforming in the repeated use process.
