Description

Cooking container and cooking utensil adopting same

[ technical field ] A method for producing a semiconductor device

The utility model relates to a kitchen appliance field especially relates to cooking container and adopt cooking utensil of this cooking container.

[ background ] A method for producing a semiconductor device

With the popularization of IH rice cookers with high-efficiency heating, consumers have higher requirements on the appearance, material and function of the rice cooker. In order to improve the effect of cooking rice in the inner container of the rice cooker, manufacturers carry out a great deal of research on the heating mode and the process material of the inner container; in order to improve the uniformity of the heating of the liner, liners and the like adopting a soaking process are provided.

The soaking inner container adopts soaking technology, and adopts soaking plate technology, i.e. the middle of the inner container is provided with an interlayer, and the interlayer is filled with a proper amount of heat-conducting liquid, and then vacuumized and packaged, so that the inner part of the inner container achieves negative pressure effect; when the liner is heated, and the interior of the liner is negative pressure; therefore, water can be boiled and gasified at a very low temperature and absorb a large amount of heat; meanwhile, the gasified steam carries the heat to the place with low temperature of the inner container at a very high speed, and the heat energy is instantly dispersed to all parts of the inner container.

If the soaking inner container (aluminum) adopts a blowing plate structure, namely two layers of composite aluminum sheets, a graphite pipeline is silk-screened between the interlayers, so that the pipeline printed with graphite is not bonded together when being compounded at high temperature because of the existence of graphite; and then the part which is not bonded together is folded and arched by pressure blowing to form the hollow vessel pipeline structure. The structural strength of the vascular pipeline is stronger than that of a traditional vapor chamber structure, and the vapor chamber of the traditional vascular pipeline structure is generally of a flat plate structure. When the interior of the pulse tube is heated, the heat-conducting liquid is quickly gasified and collided; the higher the temperature, the higher the pressure inside the vessel, and the greater the internal pressure of the vessel. When the inner container is not in a normal working environment (high temperature), the pressure inside the inner container is very high. At this time, the vessel wall is affected by high temperature and high pressure, local deformation occurs, and the arching height of the vessel is increased. If the inner container works at high temperature for a long time, vessels on the inner container are forced to slightly expand and deform due to heating.

The vessel can be divided into three areas on the surface of the inner container, one is a side vessel, one is a vessel at the transition part, and one is a bottom vessel. The three parts have different strength and hardness due to stretching forming (transition part > bottom part > side part). When the inner container is at high temperature, the pressure inside the pulse tube is basically consistent, but the strength of the wall of the pulse tube is due to the shape of the inner container; the deformation resistance strength is different. Therefore, the expansion deformation of the pulse tube has large difference at high temperature for a long time, and finally the pulse tube is deformed unevenly, so that a user can misunderstand that the inner container is damaged.

[ Utility model ] content

The utility model aims to solve the technical problem that the not enough of prior art is overcome and a even culinary art container of inflation and the cooking utensil that adopts this culinary art container are heated to heat conduction vessel is proposed.

In order to solve the technical problem, the utility model adopts the following technical scheme: the cooking container comprises a container wall which is enclosed into a cylindrical shape, wherein the container wall comprises a container side part, a container bottom part and a transition part connected between the container side part and the container bottom part, the container wall is provided with a heat conduction pulse tube which is hollow and protrudes out of the outer surface of the container wall, the heat conduction pulse tube extends from the container side part to the container bottom part, the heat conduction pulse tube is filled with a heat conduction medium, the heat conduction pulse tube positioned at the transition part has a first initial height relative to the outer surface of the transition part, the heat conduction pulse tube positioned at the container side part has a second initial height relative to the outer surface of the container side part, and the first initial height is larger than the second initial height.

In the cooking vessel described above, the heat conducting vessel at the bottom of the vessel has a third initial height relative to the outer surface of the bottom of the vessel, the third initial height being greater than the second initial height.

In the above cooking container, the first initial height is greater than or equal to the third initial height.

In the above cooking container, the third initial height is 0.8mm to 1.0 mm.

In the above cooking container, the first initial height is 1.0mm to 1.5 mm.

In the above cooking container, the second initial height is 0.5mm to 0.8 mm.

In the cooking container described above, the transition portion is in the shape of an arc that is convex outward.

In the cooking container, the container wall is formed by compounding an inner wall and an outer wall, and the outer wall is expanded to form the heat conducting vessel.

Cooking utensil, including utensil body and lid, the utensil body is equipped with the appearance chamber, be equipped with foretell cooking container in the appearance chamber.

The utility model has the advantages that:

the cooking container comprises a container wall which is enclosed into a cylindrical shape, wherein the container wall comprises a container side part, a container bottom part and a transition part connected between the container side part and the container bottom part, the container wall is provided with a heat conduction pulse tube which is hollow and protrudes out of the outer surface of the container wall, the heat conduction pulse tube extends from the container side part to the container bottom part, the heat conduction pulse tube is filled with a heat conduction medium, the heat conduction pulse tube positioned at the transition part has a first initial height relative to the outer surface of the transition part, the heat conduction pulse tube positioned at the container side part has a second initial height relative to the outer surface of the container side part, and the first initial height is larger than the second initial height. Different heights of the heat conducting pulse tube are set at the initial stage of the container wall, so that the problem that the heat conducting pulse tube on the existing cooking container expands unevenly after being heated is solved. After the container wall is lifted, the outer surface strength of the transition part is larger than that of the side part of the container, and after the container wall is heated, the expansion height of the heat conduction vessel of the transition part is smaller than that of the heat conduction vessel of the side part of the container.

In a further aspect, the thermally conductive vessel at the bottom of the container has a third initial height relative to the outer surface of the container bottom, the third initial height being greater than the second initial height. Through setting the third initial height of the heat conduction vessel at the bottom of the container to be greater than the second initial height, after the container is heated, the expansion height of the heat conduction vessel at the side part of the container is close to the expansion height of the heat conduction vessel at the bottom of the container, the difference that the expansion heights of the side part of the cooking container and the heat conduction vessel at the bottom of the cooking container are different is made up, and the heights of the heat conduction vessel at the side part of the heated container and the heat conduction vessel at the bottom of the container are basically consistent relative to the outer surface of the corresponding container.

In a further aspect, the first initial height is greater than or equal to the third initial height. Because the rigidity of the container transition part is greater than that of the container bottom, in order to make up the expansion height difference between the heat conduction pulse tube of the transition part and the heat conduction pulse tube of the container bottom after the container is heated, the first initial height is set to be greater than or equal to the third initial height in the initial stage, so that the heights of the heat conduction pulse tube of the transition part after the container is heated and the heat conduction pulse tube of the container bottom relative to the outer surface of the corresponding container are basically consistent.

In a further aspect, the third initial height is between 0.8mm and 1.0 mm. The third initial height is lower than 0.8mm, and the expansion height of the heat conducting vessel at the bottom of the heated container relative to the outer surface of the container is too low, so that a larger height difference is formed between the heat conducting vessel and the heat conducting vessel at the side part of the container; and the third initial height is greater than 1.0mm, which may cause the height of the heat conducting vessel at the bottom of the container relative to the outer surface of the container to be higher than the height of the heat conducting vessel at the side of the container relative to the outer surface of the container after heating, so that the heat conducting vessel at the bottom of the container looks more convex and causes misunderstanding for users.

In a further aspect, the first initial height is 1.0mm to 1.5 mm. The first initial height is lower than 1.0mm, and the expansion height of the heat conducting vessel at the transition part after being heated relative to the outer surface of the container is too low, so that a larger height difference can be formed between the heat conducting vessel and the side part of the container; and the first initial height is more than 1.5mm, which may cause the height of the heat conducting vessel at the transition part after being heated relative to the outer surface of the container to be higher than that of the heat conducting vessel at the side part of the container relative to the outer surface of the container, so that the heat conducting vessel at the bottom of the container looks more convex and causes misunderstanding for users.

In a further aspect, the second initial height is between 0.5mm and 0.8 mm. A second initial height of less than 0.5mm may result in a poor heat transfer effect with too little heat conducting vessel space on the sides of the container; and the expansion height of the heat conducting vessel at the side part of the container relative to the outer surface of the container after the heat is heated is too high, the heat conducting vessel at the side part of the container is obviously protruded, and the heat conducting vessel at the transition part is also protruded to a larger height relative to the outer surface of the container, which exceeds the allowable range of the manufacturing process.

In a further aspect, the transition portion is a convex arc. The transition part is in a convex arc shape, so that the side part of the container and the bottom of the container are in smooth transition, dead angles are avoided, food contacted with the transition part can be uniformly heated, and better food taste is obtained.

In a further aspect, the container wall is formed by compounding an inner wall and an outer wall, and the outer wall is expanded to form the heat conducting vessel. The process method adopting the form of compounding the inner layer wall and the outer layer wall is mature, the yield is high, and meanwhile, the sealing performance of the heat conducting vessel at each part can be ensured.

Cooking utensil, including utensil body and lid, the utensil body is equipped with the appearance chamber, be equipped with foretell cooking container in the appearance chamber. Because the cooking utensil adopts the cooking container, on the basis of obtaining comparatively even heating food, the cooking container appearance after the heating can also be guaranteed to be even, and the misunderstanding of a user is avoided.

These features and advantages of the present invention will be disclosed in more detail in the following detailed description and the accompanying drawings.

Example one

As shown in fig. 1 and 2, the cooking container comprises a container wall 10 which is enclosed into a cylindrical shape, the container wall 10 comprises a container side part 11, a container bottom part 13 and a transition part 12 connected between the container side part and the container bottom part, the container side part 11 starts to extend downwards from an opening of the container, can extend downwards vertically or slightly extend downwards in an inclined manner approaching to the center direction, and the transition part 12 is in an outward convex arc shape and can be fully contacted with a heating part of the cooking appliance, so that the cooking container can be heated uniformly, cooked food can obtain better taste, dead angles are avoided by the outward convex arc transition part 12, and the cooking container is more convenient to clean.

As shown in fig. 2 and 6, the dotted line in fig. 6 indicates the position where the heat conducting vessel 20 expands after being heated. The container wall 10 is formed by combining an inner wall 14 and an outer wall 15, the combination process being as described in the prior art, with the outer wall 15 being expanded to form a thermally conductive vessel 20. The heat conducting vessel 20 is a hollow structure and filled with a heat conducting medium, and the heat conducting vessel 20 extends from the container side 11 of the container wall 10 to the container bottom 13. Thermally conductive pulse tube 20 at transition 12 has a first initial height H1 relative to the outer surface of transition 12, and thermally conductive pulse tube 20 at container side 11 has a second initial height H2 relative to the outer surface of container side 11, with first initial height H1 being greater than second initial height H2. Thus, after the cooking container is heated, because the heat conducting vessel 20 of the container side portion 11 is more easily heated to expand, the expansion height is relatively more convex, and the relative height of the heat conducting vessel 20 of the transition portion 12 expanded after being heated is lower than that of the heat conducting vessel 20 of the container side portion 11, during manufacturing, the height of the heat conducting vessel 20 of the transition portion 12 is higher than that of the heat conducting vessel 20 of the container side portion 11, the expansion height difference of the heat conducting vessel 20 at two positions after being heated and expanded is compensated, and the height of the heat conducting vessel 20 of the transition portion 12 relative to the container side portion 11 after being heated is kept to be basically consistent with the height of the heat conducting vessel 20 of the container side wall relative to the container side portion 11. The used cooking container looks like that the protruding degree of the heat conducting vessel 20 of the side part 11 of the container is basically equal to the protruding degree of the heat conducting vessel 20 of the transition part 12, the overall appearance is kept basically consistent, and the misunderstanding that the cooking container is damaged due to heat deformation is avoided for a user.

As shown in fig. 3, the heat conducting vessel 20 located on the container side 11 has a second initial height H2 relative to the outer surface of the container side 11, the second initial height H2 is 0.5 mm-0.8 mm, in this embodiment, the second initial height H2 is 0.7mm, the second initial height H2 is related to the size of the inner volume of the heat conducting vessel 20 on the container side 11, if the second initial height H2 is less than 0.5mm, the volume of the heat conducting vessel 20 on the container side 11 is too small, which may affect the heat conducting effect; while the second initial height H2 exceeds 0.8mm, it is preferred to control the second initial height H2 to be less than 0.8mm because the first initial height H1 is greater than the second initial height H2, and the second initial height H2 is too great, which results in a greater first initial height H1, such that after heating, the thermal vessel 20 of the transition portion 12 expands, which may cause the outer wall 15 to break beyond the pull-up limit.

As shown in FIG. 4, the thermally conductive vessel 20 at the transition portion 12 has a first initial height H1 relative to the outer surface of the container side portion 11, the first initial height H1 is 1.0mm to 1.5mm, and the first initial height H1 is 1.3mm in this embodiment. Since the material strength of the transition portion 12 is the greatest, that is, the deformation amount of the heat conducting vessel 20 of the transition portion 12 is the smallest after being heated, it is necessary to give the first initial height H1 a larger size at the manufacturing stage, and if the first initial height H1 is less than 1.0mm, the height of the heat conducting vessel 20 of the container side portion 11 relative to the outer surface of the container after being deformed by heat will be larger than the height of the heat conducting vessel 20 of the transition portion 12 relative to the outer surface of the container after being deformed by heat, which is too large to achieve the predetermined effect, and the user will obviously perceive that the deformation of the container side portion 11 is larger than that of the transition portion 12; and the first initial height H1 exceeds 1.5mm, the height of the heat conducting vessel 20 of the transition part 12 relative to the outer surface of the container after being deformed by heat is obviously higher than the height of the heat conducting vessel 20 of the side wall of the container relative to the outer surface of the container after being deformed by heat, which also causes that a user can obviously perceive the deformation of the cooking container after using the cooking container, thereby causing misunderstanding of the quality of the cooking container.

The utility model also discloses a cooking utensil, including utensil body and lid, the utensil body is equipped with and holds the chamber, places above-mentioned culinary art container in holding the chamber. The cooking utensil has a heating element in the utensil body, can heat cooking utensil, and the lid is used for sealing cooking container when cooking, keeps cooking container's temperature in the cooking process. After the cooking appliance adopting the upper cooking container is used for a period of time, although the heat conducting vessels 20 of the container side part 11 and the transition part 12 are deformed due to heating in the cooking process, because the initial heights of the heat conducting vessels 20 of the container side part 11 and the heat conducting vessels 20 of the transition part 12 are differentiated in the early stage, the sizes of the heat conducting vessels 20 of the container side part 11 and the transition part 12 protruding out of the outer surface of the container wall 10 can be kept basically consistent after the cooking appliance is used, and the misunderstanding of the product quality by a user is avoided.

Example two

As shown in fig. 2 and 5, the difference from the first embodiment is that: with the added definition of the heat conducting vessel 20 of the container bottom 13, the heat conducting vessel 20 at the container bottom 13 has a third initial height H3 relative to the outer surface of the container bottom 13, the third initial height H3 being greater than the second initial height H2. Because the expansion amplitude of the heat conducting vessel 20 at the bottom 13 of the container after being heated is smaller than that of the heat conducting vessel at the side 11 of the container after being heated, when the cooking container is manufactured, the third initial height H3 is larger than the second initial height H2, and after the cooking container is heated and expanded, the expansion heights of the heat conducting vessel 20 at the side 11 of the container and the heat conducting vessel 20 at the bottom 13 of the container are basically consistent relative to the corresponding container wall 10.

Since the container wall 10 includes the container side 11, the container bottom 13 and the transition portion 12, in order to keep the sizes of the three portions of the heat conducting vessels 20 substantially consistent with the sizes of the corresponding outer surfaces of the container wall 10 after being expanded by heat, the first initial height H1 is greater than or equal to the third initial height H3, that is, the sizes of the heat conducting vessels 20 of the transition portion 12 and the heat conducting vessels 20 of the container bottom 13 are defined, and since the strength of the transition portion 12 is the highest and the deformation amount thereof is the smallest, the first initial height H1 of the heat conducting vessels 20 of the transition portion 12 is the highest of the three initial heights, while the third initial height H3 of the heat conducting vessels 20 of the container bottom 13 is centered among the three initial heights, and the second initial height H2 of the heat conducting vessels 20 of the container side 11 is the lowest of the three initial heights.

Further, the third initial height H3 is 0.8mm to 1.0mm, and the third initial height H3 is 0.9mm in this embodiment. The third initial height H3 is less than 0.8mm, and the height difference between the cooking container and the heat conducting vessel 20 on the side part 11 of the container after being deformed by heat is too large relative to the corresponding outer surface of the container wall 10, so that the predetermined effect cannot be achieved; and the third initial height H3 is greater than 1.0mm, after the cooking container is deformed by heating, the height difference between the heat conducting vessel 20 and the outer surface of the bottom 13 of the container is much greater than that between the heat conducting vessel 20 and the outer surface of the transition portion 12, which may cause the false appearance of container damage.

Other contents not described in this embodiment may refer to embodiment one.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification which does not depart from the functional and structural principles of the present invention is intended to be included within the scope of the claims.
