Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cooking appliance such as a rice cooker used in general households.

2. Description of the Related Art A conventional cooking device of this type has a structure as shown in FIG. That is, in FIG. 4, a cooking device main body 21 is provided, and a pot 22 is installed inside the cooking device main body 21 in a manner that it can be comfortably attached. Reference numeral 23 denotes an outer lid that covers the upper opening of the cooking device main body 21, and the outer lid 23 is provided with a steam hole 24 for discharging steam inside the cooking device main body 21. Reference numeral 26 denotes an inner lid provided below the lid body 23, and this inner lid 25 moves to crush the bubbles 26 generated inside the pot 22 so that they do not directly flow out of the cooking device main body 21. Therefore, this inner lid 25 is provided with a hole 27 on the upper surface 28 for the purpose of blowing out air.
In addition, a partition plate 29 is provided to prevent the blown sticky liquid from easily boiling over.

Reference numeral 3o denotes a suction hole, which is provided to suck in the sticky liquid 31 that has accumulated inside the inner lid 25 after cooking is completed.

Problems to be Solved by the Invention However, in the conventional configuration described above, the heater 32 is provided inside the lid body 23, and the inner lid 25 is heated by radiated heat from the heat dissipation plate 33 on the lower surface of the lid body, and the inner lid 26 is heated. This is an indispensable factor to prevent condensation and whitening of the rice and to make the food more delicious.In a cooker that uses Ipower, the heat dissipation plate 33 and the inner lid 25 are close to each other. However, since the partition plate 29 could not be provided, a large amount of foaming gas concentrates on the outlet hole 27 of the inner lid 25, blows out of the cooker main body 21 through the steam hole 24, and the outer lid There is a problem in that not only the cooking device 23 but also the table on which the cooking device main body 21 is placed are also soiled. The main reason for this is that the heat sink 33 and the inner lid 26 are close to each other.
Even though the bubbles are easily extinguished by the heater 32, the sticky substance blown out from the blowout hole 27 immediately flows into the steam hole 24. The present invention addresses the above-mentioned problems and aims to prevent slime from flowing out of the cooking device.

Means for Solving the Problems In order to achieve the above object, the present invention provides a cooking device body, a pot detachably housed in the cooking device body, and an outer lid covering an upper opening of the cooking device body. a radiator plate disposed below the outer lid and having a steam exhaust port for discharging steam inside the cooker body; a heater for heating the radiator plate; and a bonito powder provided between the radiator plate and the pot. The device includes an inner lid having a blow-off hole for blowing out stickiness, and the outer cover is provided with a step in a direction approaching the blow-off hole of the inner cover.

Function In the above configuration, for example, when a heater that heats the heat sink prevents condensation on the inner lid and whitening of the rice, and when cooking is performed at high power, the sticky liquid blown out from the air outlet of the inner lid becomes foamy. However, by creating a new level difference, the waste that blows out from the outlet near the steam outlet does not go directly to the steam outlet, and instead is transferred to the heat sink, which has become hot due to the heater. The bubbles disappear during the long period of time that the steam is trapped in the inner lid, and the sticky substance does not blow up into the steam outlet.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

In Fig. 1, 1 is a cooking device main body, and this cooking device main body 1
A pot 2 is removably installed inside.

Reference numeral 3 denotes an outer lid that is rotatably supported on one side of the upper opening of the cooking device main body 1 and covers this upper opening.
is equipped with a steam exhaust port 4 that serves as a path for discharging the steam inside the pot 2 to the outside of the cooking device main body 1.

Reference numeral 5 denotes a heat sink attached to the outer lid 3, which is heated by a heater 6. Reference numeral 7 denotes an inner lid holder shaft fixed to the heat dissipation plate 6, and an inner lid 9 is attached to this inner lid holder shaft 7 via an inner lid holder 8 made of rubber. The inner lid 9 is provided with a blow-off hole 10 for blowing out steam accompanied by slime in the upper part 9a near the center, and a suction hole 11 in the lower part 7b to drop the sticky liquid into the pot 2 after cooking is completed. ing. 12 is a step on the heat sink 5, which is convex downward. FIG. 2 is a top plan view of the inner lid 9, and FIG. 3 is a top plan view of the heat sink 5, where 12 is a step.

The operation of the above configuration will be explained next.

When cooking rice with rice and water in pot 2, if you cook with Ipower or accidentally add more water than the appropriate amount for the amount of rice, when the water boils, steam and Excess boiling water: i becomes bubbles and rises to the upper part of the inner cover 9 through the air outlet 10 of the inner cover 9. In this case, air outlet 1
o and the area ratio of the suction hole 11, the air outlet hole 1o
If is made sufficiently large, most of the air bubbles will be concentrated in the air outlet hole 1o, and no air bubbles will be generated from the suction hole 11.

The foam that rises to the top of the inner lid 9 is removed from the steam outlet 4.
However, the steam blown out from the outlet near the steam outlet 4 is largely detoured by the step 12 and reaches the steam outlet 4.

In this phenomenon, while moving between the heat dissipation plate 6 and the inner lid upper stage 9a, it comes into contact with the heat dissipation plate 6, which has been heated to a high temperature by the heater 6, and the foam disappears. For this reason, the amount of foam-like sticky substance is reduced, and the foam does not blow out from the cooker body and boil over.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, a step is provided near the outlet of the inner cover of the heat sink to prevent bubbles from flowing directly to the steam outlet; The path that bubbles travel becomes longer, making it easier for bubbles to disappear. Therefore, even if you cook at high power or accidentally add more water than the appropriate amount for the amount of rice, steam will not come out from the steam outlet, and the result will be , it is possible to provide a safe and clean cooker without boiling over.
