  However, in the conventional lid shape and configuration, the dew condensation water returns from the lid to the kettle, and the rice near the kettle wall tends to deteriorate with much moisture like rice cake, and is not delicious. For the preservation of rice, the small amount of high water content rice has an enzyme-like adverse effect on the preservation of the whole rice. In order to solve this problem, there is currently a method of strengthening local heating on the side of the kettle, but there are problems such as extra costs.

  The present invention solves the above-mentioned conventional problems, has a function of preventing the generation of high moisture content rice on the design structure of the lid geometry, and is also used for the surface antibacterial coating treatment of the lid. It aims at providing the technical result of the rice-cooker functional lid which can cook rice with a long and long period of storage and a homogeneously delicious rice by the effect of the mutual effect.

  In order to solve the conventional problems, the rice cooker functional lid of the present invention includes a functional lid having a homogeneous rice cooking function set with the rice cooker, and the functional lid has a functional shape design, a surface processing treatment, and the like. The method is added to the rice cooker lid with an effective function to cook homogeneous and delicious rice.

  As a result, the condensed water of steam on the rice cooker lid flows from the high position of the lid to the low position by gravity, and falls in the distribution according to the design along the flow conduction geometry, ensuring relatively homogeneous rice. Can be.

  In addition, both sides of the joint between the hook and the lid are processed into a horizontal plane, and the sealing performance is improved by condensed water. Therefore, the lid's own weight (eg 14kg for business use) or pressure applied, Increases temperature and air pressure, and has a positive effect on the rice cooking process.

  The pot lid of the present invention does not have local high-moisture rice and can cook delicious, homogeneous rice, which can extend the storage period.

By introducing the functional lid of the rice cooker, the condensed water generated in the kettle lid is properly conducted along the geometric shape, and there is no localized high-moisture rice to cook homogeneous delicious rice. The storage period of rice can be extended by the combined effect of the carbon antibacterial coating.

  In the second invention, in particular, the geometric structure of the functional lid of the first invention is a shape that adjusts the falling distribution of condensed water of rice cooking evaporation, so that the condensed water can be obtained by the directed flow operation of the above-described configuration. It will be processed with appropriate fall distribution, and it will be possible to eliminate local high moisture rice.

  3rd invention uses the condensed water of rice cooking evaporating especially the delicious rice cooking of 1st invention, makes the joint surface of a kettle and a lid into a horizontal surface, and the shape composition of the packing effect by the tension of condensed water between flanges As a result, the tightness of the pot and lid is improved, so the lid's own weight (eg, 14 kg for business use) or the pressure applied to the lid raises the temperature and pressure inside the kettle, and the rice cooking process Can have a positive effect.

  The fourth aspect of the invention is the second aspect of the invention, in particular, the flow of condensed water of evaporation is a directed flow, and the method for adjusting the fall distribution is to press the letter or flower pattern stamp on the rice cooker lid plate, Mechanical strength and design can be improved, and energy-saving and low heat capacity thin plate materials can be selected.

  In the fifth aspect of the invention, in particular, the functional film of the first aspect of the invention is improved in resistance to wear and wear resistance by making a functional film by vacuum deposition of a carbon-based material on the surface of the side of the rice cooker lid. Furthermore, it is possible to keep the rice effectively by acting as a fungus for suppressing the fungus of carbon in a place called “lid” where water easily collects and begins to rot.

  In the sixth aspect of the invention, in particular, in order to achieve the function of adjusting the fall distribution of the condensed water of the second or fourth aspect with the geometric configuration of the pot lid, the stamping press processing with a letter or flower pattern on the rice cooker lid plate material is performed. The surface of the side of the rice cooker lid is easy to clean and has a cornerless slope, so that it is shaped so that dirt does not accumulate easily and can be easily cleaned. The service life of the functional film of the fifth invention Extending is also connected.

  In the seventh aspect of the invention, in particular, the functional film is formed on the surface of the rice cooker lid of the first or fifth aspect of the invention. By surface treatment for the purpose of obtaining heat isolation performance, heat exchange performance and heat retention performance can be improved, and rice cooker efficiency performance and energy saving performance can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a rice cooker set configuration using a functional lid in the first embodiment of the present invention. FIG. 2 shows the shape of the functional lid.

  In FIG. 1, the rice cooker 2 is made of metal having a certain degree of mechanical strength and good thermal conductivity. The connection surface 3 with the hook lid 1 is processed into a horizontal plane.

  The operation | movement and effect | action are demonstrated below about the shuttle 2 and the lid | cover 1 which were comprised as mentioned above.

  First, when the hook lid 1 is closed, the four surfaces are processed into a horizontal plane, so that the joint surface 3 and the four surfaces in FIG. The rice cooker flange 7 rises to a certain water level from the joint surface between 3 and 4 when the rice is cooked, and gathers at 7 and 4 locations. The 3 and 4 dense joint surface effects and the synthetic sealing effect of the hook flange 7 are the new functions of condensed water tension and water packing effect instead of the conventional rubber packing sealing method which is difficult to clean.

  As described above, in the present embodiment, by using condensed water as the water packing, the conventional rubber packing sealing method that is difficult to clean becomes unnecessary, and hygienic cleaning can be facilitated.

  In addition, by using the packing sealing method of the present embodiment as a packing material due to the tension effect of condensed water, an aging material such as a rubber packing material becomes unnecessary, and the service life of the rice cooker can be improved.

  In addition, in the case of a commercial rice cooker, the dense horizontal plane connection of 3 and 4 surfaces of this embodiment works with the condensed water packing effect by the dead weight of the lid to improve the sealing performance. As a result, more delicious rice can be cooked.

(Embodiment 2)
FIG. 2 is a structural diagram of the second embodiment of the present invention.

  In FIG. 2, the inner surface of the rice cooker lid is composed of 3, 5 and 6 surfaces. The coupling between the surfaces is a smooth coupling so that the condensed water falls from the surface 5 with a uniform distribution. On the surface 5, in order to realize the function of adjusting the fall distribution of the condensed water by the directed flow method using the flow of the condensed water of rice cooking evaporation, a shape in which a stamp is stamped with letters or a flower pattern is designed.

  The operation and action of the hook lid 4, 5 and 6 configured as described above will be described below.

  First, the four surfaces in FIG. 2 are the horizontal surface packing operation and sealing action of the first embodiment, but the connection with the five surfaces in FIG. 2 is the direction in which the five surfaces extend downward, so that the condensation on the lid surface Design consideration will be given so that water does not flow in the outer sphere direction.

  As described above, in the present embodiment, the cross-sectional shape of the conventional rice cooker lid is almost flat or the center of the lid is slightly elevated, but the present invention is different from the conventional running and the high temperature when cooking rice is heated. In order to form a geometrical shape in which condensed water falls at the boiling point (where the potholes are easily formed), the shape is inverted. Similarly, in the central part of the kettle where the boiling temperature distribution is relatively low and the high-temperature water is difficult to flow, the surface 6 is formed in a concave inner circle shape so that the fall of condensed water can be accommodated, and the condensed water is concentrated locally. The bad effects are that the rice has a lot of moisture like rice cake, and it can solve the problem of unsavory rice.

  Although there is a technology that flows hot water in the center of rice by adjusting the slope of the bottom of the kettle, this is not a limitation.

  Further, in the present embodiment, when a heating source is added to the opposite side of the inner plate 4, 5, 6 surface of the constructed lid, the surface treatment or functional film is applied to the inner plate 4, 5, 6 surface. By processing, the heat conduction and heat radiation performance can be improved, and the problem of unsavory rice that can be more effectively changed in water content can be solved.

  As described above, the rice cooker functional lid according to the present invention is a low-cost method that eliminates the need for localized high-moisture rice and cooks homogeneous and delicious rice. A wide range of applications of the technology of the present invention can be applied to industrial fields related to the manufacturing, sales, product quality, product storage, and transport processes of rice products in the food industry, commercial food service industry, restaurant industry, restaurant industry, cooking rice cooking technology .
