As shown in fig. 1 to 4, the utility model provides a high temperature-uniforming electric cooker inner container, the high temperature-uniforming electric cooker inner container includes:
the liner comprises a liner body 10, wherein the liner body 10 comprises an inner metal layer and an outer metal layer, and the outer metal layer is positioned on the outer side of the inner metal layer; the heat transfer pipeline 20 is a pipeline combination with different rules, is positioned on the bottom surface and the side wall of the outer metal layer, and is filled with a heat transfer working medium for transferring the temperature of the bottom of the inner container body 10 to the high point position of the inner container of the high temperature-uniforming electric cooker, so that the whole inner container of the high temperature-uniforming electric cooker is uniformly heated and insulated; and an extension part 30 positioned at the uppermost end of the inner container body 10.
The working principle of the inner container of the high temperature uniformity electric cooker of the utility model is that: the inner container of the high-temperature-uniformity electric rice cooker is placed on a heating disc in the electric rice cooker, the bottom of the inner container of the high-temperature-uniformity electric rice cooker generates heat under the action of the heating disc, the heat transfer pipelines 20 on the inner container of the high-temperature-uniformity electric rice cooker are communicated with each other in a staggered mode and are distributed on the outer surface of the inner container of the high-temperature-uniformity electric rice cooker, when the heat of the heating disc is transferred to the heat transfer pipelines 20, the heat transfer working medium in the heat transfer pipelines 20 rapidly transfers the temperature of the bottom of the inner container of the high-temperature-uniformity electric rice cooker to the high-temperature position of the inner container of the high-temperature-uniformity electric rice cooker through the working mechanism of phase change heat transfer, so that the inner container of the high-temperature-uniformity electric rice cooker is in an integral heating state, and the inner container of the high-temperature-uniformity electric rice cooker is uniformly heated efficiently.
In addition, the heat transfer pipeline combination with different laws can facilitate the heat transfer working medium in the heat transfer pipeline to better flow, thereby having quicker heat transfer effect; compared with the traditional electric cooker liner, the high temperature-uniformity electric cooker liner is not limited to only the bottom part of the liner in the heating area but expands the heating area to the whole liner by adding the heat transfer pipeline 20 and the heat transfer working medium in the heat transfer pipeline, so that the whole structure is simple, and the weight is not obviously changed.
As shown in fig. 1-3, the heat transfer circuit 20 is illustratively formed from the outer metal layer via an inflation process. And (3) blowing the outer metal layer, forming the heat transfer pipeline 20 on the outer surface of the liner body 10, wherein the heat transfer pipeline 20 protrudes out of the outer surface of the liner body 10, and is filled with a heat transfer working medium, and then carrying out sealing process treatment. When the electric cooker works, the bottom of the inner container body 10 can be fully contacted with the heating disc, so that the temperature rise of the heat transfer working medium is accelerated, the temperature at the bottom of the inner container body 10 is quickly conducted to the high point position of the inner container of the electric cooker with high temperature uniformity, the inner container is heated uniformly, and when the temperature reaches a threshold value, the temperature in the inner container can be kept uniform under the action of the heat transfer working medium after tripping.
As an example, the shape of the heat transfer pipeline 20 is a combination of intersecting straight lines and curved lines, and the patterns are radially distributed on the bottom surface and the side wall of the outer metal layer from small to large. The heat transfer pipeline 20 is in shape fit with different regular pipelines, and the heat transfer working medium can flow in the heat transfer pipeline to achieve a better effect.
In a specific embodiment, the pattern of the heat transfer pipeline 20 is a honeycomb grid, the patterns are radially distributed on the bottom surface and the side wall of the outer metal layer from small to large, the pattern of the heat transfer pipeline 20 at the bottom of the inner container body 10 is relatively small and dense, the contact area between the heat transfer pipeline 20 and a heating disc is increased, and the heating speed of the inner container of the electric rice cooker is accelerated; the heat transfer pipeline 20 on the side wall has a relatively large pattern size compared with the heat transfer pipeline 20 on the bottom, because cooked food is mainly concentrated on the middle lower part of the inner container of the electric rice cooker, the bottom accelerates the heating of the food, heat can spread upwards from the bottom surface inside the inner container body 10, although the temperature of the side wall is lower than the temperature of the bottom, the temperature of the whole inner container of the electric rice cooker is in a high temperature state in combination with the heat transferred from the bottom surface inside the inner container body 10, so that the processing technology of the inner container body 10 is reduced, and the whole heat can be ensured.
In a preferred embodiment (as shown in fig. 1 to 3), the heat transfer pipeline 20 is shaped like a spider-web, and the patterns are radially distributed on the bottom and the side wall of the outer metal layer from small to large, and a straight pipeline can facilitate better flow of the internal heat transfer medium, so that the heat transfer pipeline has a quicker heat conduction effect, a curved pipeline not only has the function of retaining the heat transfer medium, but also has a better heat preservation effect, and the combination of two different pipelines is matched, so that the heat transfer medium can flow in the heat transfer pipeline 10, and the inner container of the electric rice cooker has a better effect on heat transfer and temperature uniformity.
As an example, the heat transfer pipeline 20 is a vacuum sealed environment, and the proportion of the heat transfer working medium filled in the heat transfer pipeline 20 in the space is in a range of 10% to 50%.
It should be noted here that the heat transfer pipes 20 are communicated with each other on the liner body 10 and extend over the outer surface, so that the temperature of the liner body 10 is uniform, the heat transfer efficiency is as high as 95%, and the vacuum sealing environment ensures the heat transfer efficiency of the liner body 10 and improves the heat transfer capacity.
As shown in fig. 1 and 3, the highest point of the heat transfer circuit 20 is lower than the extension portion.
It should be noted that, when the electric cooker is operated, the food to be cooked is generally concentrated on the middle lower part of the inner container of the electric cooker, the main heating area is concentrated on the bottom part of the inner container of the electric cooker, and if too many heat transfer pipelines 20 are arranged on the side wall, the heat transfer working medium filled inside will cause the heat in the inner container of the electric cooker to be too high, so that the food is easily burnt during cooking, and the material resources are wasted. When the shape of the heat transfer pipeline 20 is a combination of a straight line and a curve, the liner of the electric cooker is heated in a better fit, and the structural design of the curve can better retain working media, so that the electric cooker has a better heat preservation effect.
As an example, the outer surface of the inner container body 10 is coated with an iron-containing coating, and a heating plate of the electric cooker is used for heating the inner container of the electric cooker with high temperature uniformity.
It should be noted here that the heating plate heats the inner container body 10 identically to the electromagnetic oven, and both generate an alternating magnetic field through the electronic circuit board components, and when the bottom of the inner container body 10 coated with the iron-containing coating is placed on the heating plate, the inner container body 10 cuts the alternating magnetic lines of force to generate an alternating current (i.e. eddy current) at the bottom metal part of the inner container body 10, and the eddy current makes the iron molecules of the cooker move randomly at a high speed, and the molecules collide and rub with each other to generate heat energy. The type of the iron-containing coating can be set according to actual needs, and is not limited herein as long as the iron-containing coating can generate heat energy through physical reaction with the heating plate.
As an example, the inner container body is made of a composite metal layer composed of the inner metal layer and the outer metal layer through a stretching process. The inner metal layer is a single-layer structure of a stainless steel layer or an aluminum material layer, or a laminated structure of two combinations of the stainless steel layer and the aluminum material layer.
When the inner metal layer is a single-layer structure of a stainless steel layer, for example, a 304 plate layer can be selected, and 304 stainless steel has excellent stainless corrosion resistance and better intergranular corrosion resistance. When the inner metal layer is of an aluminum material layer single-layer structure, the surface of the inner metal layer needs to be treated, so that the contact part of the inner container and food meets the food sanitation standard, and the non-adhesiveness of the inner container is improved, for example, the inner container can be coated with a ceramic coating or a non-stick coating. When the inner metal layer is a laminated structure of two combinations of a stainless steel layer and an aluminum material layer, the inner metal layer and the outer metal layer are rolled together to form the inner container body 10 by stretching, and the lamination can be divided into three conditions: the aluminum alloy composite laminated plate has the advantages that the outer aluminum layer and the inner steel layer are laminated in a composite mode, the inner surface is made of stainless steel, the requirement that the inner surface is made of stainless steel is met, and the heat conducting performance of the stainless steel is improved by utilizing the integral soaking effect of an aluminum material; secondly, two layers of outer steel and inner aluminum are laminated in a composite mode, the inner wall is an aluminum layer, the outer layer is stainless steel, the surface of the aluminum layer cannot be in direct contact with food, and the surface needs to be treated; and thirdly, steel-aluminum-steel three-layer composite lamination, wherein the inner layer and the outer layer are both stainless steel layers, and the middle layer is an aluminum material layer. In addition, in this embodiment, a PCI expansion board is preferably used as the outer metal layer, so that the heat transfer pipeline 20 is easily formed. The thickness range of the electric cooker inner container is 2.5 mm-3.5 mm, 3 mm-3.5 mm is generally preferred to be adopted to form a 'thick kettle inner container', namely, the inner container bottom and the kettle wall are made of thicker metal layers, as food transfers heat by the electric cooker inner container, the transferred heat is in direct proportion to the heat transfer area under a certain condition, namely, the heat transfer effect and the thickness of the electric cooker inner container are in direct proportion, and the heat transfer condition required by cooking can be fully met only when the thickness of the electric cooker inner container reaches a certain thickness, so that a better cooking effect is achieved.
As shown in fig. 1 and 3, the bottom of the inner container body 10 is an arc bottom. The arc bottom is helpful for boiling convection when the inner container of the electric rice cooker is heated, and can be used for boiling heating fully.
