Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION Field of the Invention The present invention relates to a rice cooker and an object of the present invention is to prevent rice spillage generated during cooking from spilling out of the rice cooker.

Conventional technology A conventional rice cooker has a radiator plate and inner lid arranged inside the outer lid, and has a double structure to separate steam generated during cooking rice and rice from the radiator plate and the inner lid space. To prevent spills.

The problem to be solved by the invention In the above-described conventional configuration, when the ratio of the amount of water to rice is increased, such as when cooking soft rice according to preference, the space between the inner lid and the radiator plate is required. And the separation of steam was insufficient, causing spillage. Further, for this reason, it is necessary to set the electric power of the rice cooker at the bottom lower, which causes a disadvantage that the rice cook time becomes longer.

Means for Solving the Problems In order to solve such a conventional problem, in the present invention, a part of the heater is arranged around the steam port opened in the heat sink, so that the temperature around the steam port during rice cooking is increased. It is something to keep.

Operation According to the above configuration, when the inner pot is heated at the time of cooking rice, steam and rice generated by rice and water reach the lower surface of the heat sink. Here, when the steam exceeds the separation capacity of the steam, the foam comes into contact with the radiator plate and advances to the steam port with the steam. The resulting foam is evaporated around the steam port and discharged from the steam port to improve the performance against spills.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing a rice cooker according to an embodiment of the present invention, and FIG. 2 is a view showing an example of a pattern shape of a lid heater composed of a silicon rubber heater mounted on an upper surface of a heat sink.

In FIG. 1, 1 is an outer lid, 2 is a steam port provided on the outer lid 1, 3 is a radiator plate disposed on the inner surface of the outer lid 1, 4 is a silicone rubber disposed on the upper surface of the radiator plate 3. A cord-shaped lid heater composed of a heater, 5 is an aluminum tape for attaching the lid heater 4 to the heat sink 3, 6 is an inner lid, 7 is an inner pot,
Reference numeral 8 denotes an outer pot, 9 denotes a rice cooker which is a heat source for rice cooker provided on the outer bottom of the inner pot 7, and 10 denotes a main body.

In FIG. 2, reference numeral 3 denotes a heat sink, and reference numeral 2 denotes a steam port opened in the heat sink 3, which communicates with the steam port of the outer lid 1. 4
Is a lid heater arranged in an appropriate pattern on the upper surface of the heat radiating plate 2, a part of which is arranged around the steam port 2.

Next, the operation of the present embodiment having the above configuration will be described.

When the rice is cooked as shown in FIG. 1, the steam generated from the inside of the inner pot 7 and the steam reach the lower surface of the radiator plate 3, where the steam is separated and the steam is discharged through the steam port 2. However, in the case where soft rice is cooked according to the taste, a cycle in which the rice foam comes into contact with the heat radiation plate 3 and pops out when the ratio of the amount of water to the rice is increased is repeated. By arranging the lid heater 4 so that the temperature around the steam port of the radiator plate 3 becomes 100 ° C. or higher before reaching the steam port 2 while repeating this cycle, the foam of the rice cake is evaporated around the steam port 2. The steam is discharged from the steam port 2 as steam.

Effects of the Invention As described above, according to the present invention, a part of the lid heater is arranged around the steam port of the heat sink, and there is an effect that the performance against spillover can be improved by keeping the surrounding area at a high temperature.
