Abstract

PURPOSE:To achieve ease of handling at a low cost and prevent drying by substituting a silicone-made steam cylinder for an internal lid, and maintaining the temperature of rice in a pot during the preservation of heat without boiling oven. CONSTITUTION:A surface with no steam hole 10 of an external lid 5 is lower in temperature than the inside of a pot 2. Foam generated is cooled down in the course of a through hole 17 and with the surface 15 having no stem hole 10 to form liquid goo, which flows reversely from top to bottom through the through hole 17 to prevent boiling over outside the main body 1 of a cooker. The top surface 18 of the through hole 17 of a steam cylinder 12 is positioned above the lower end 19 of a rib 16 which divides the surface 14 having the steam hole 10 of the external lid 5 and the surface 15 without the steam hole 10. Therefore, during the preservation of heat, the temperature of the rice cooked in the pot 2 is not affected by the outside air, facilitating the maintaining of the temperature as the heat of the rice cooked is hard to transmit outside the main body 1 of the cooker with air as medium. The moisture in the pot 2 is also hard to escape outside the main body 1 of the cooker to prevent the drying of the cooked rice. Thus, the steam cylinder 12 is made of material inexpensive and highly resistant to the adherence of goo or the like, thereby achieving ease of handling with easier washing.

In FIG. 4, a cooker main body 22 has a bottomed cylindrical pan 23 detachably installed therein. The lid 24 is rotatably supported on one side of the upper opening of the cooker main body 22 and covers the upper opening. The lid 24 is provided with a steam hole 25 which is a passage for discharging the steam in the pan 23 to the outside of the cooker main body 22. An inner lid holder shaft 26 is fixed to the center of the lid body 24, and an inner lid 28 is detachably attached to the inner lid holder shaft 26 via a rubber inner lid holder 27. The inner lid 28 is provided with a hole 29 through which steam generated in the pot 23 passes.

In the above structure, when rice is cooked, the pot 23
Bubble-like sticks are generated from the inside with steam. The steam reaches the upper surface of the inner lid 28 through a hole 29 provided in the inner lid 28,
The cooker main body 2 passes through the steam holes 25 provided in the lid 24.
2 is discharged to the outside. Further, the foam-like sash does not easily rise to the upper surface of the inner cover 28 due to the inner cover 28, and prevents the spilling of the spilled material outside the cooker main body 22.

When the temperature is kept warm, the inner lid 28 gently separates the rice in the pan 23 from the outside of the cooker main body 22 to maintain the temperature of the rice and prevent the rice from drying.

[0007]

In such a conventional rice cooker, the inner lid 28 is required, and the inner lid holder shaft 26, the inner lid holder 27, and the inner lid holder shaft 26 are covered to provide the inner lid 28. There is a problem that the number of work steps for fixing to the body 24 is required and it is costly, and that it is necessary to wash the inner lid 28 that is soiled with a stick and the usability is poor.

The present invention solves the above problems, is less costly than conventional ones, is excellent in usability, and does not spill out of the body of the cooker when cooking rice, and the temperature of the rice in the pan is kept warm. The first object is to provide a cooker capable of maintaining heat and preventing drying.

A second object is to provide an effective means for preventing spillage of the stick on the cooker main body during rice cooking.

[0010]

In order to achieve the first object, the present invention provides a cooker main body, a pan detachably accommodated in the cooker main body, and an upper opening of the cooker main body. A lid body for opening and closing the portion, and a tubular packing interposed between the steam hole portion of the outer lid forming the upper surface of the lid body and the steam hole portion of the lid cover forming the inner surface of the lid body, , A steam cylinder is provided in the steam hole portion of the lid cover, a cylindrical wall that abuts the packing around the steam hole on the lower surface of the outer cover, and a surface having the steam hole in the circumference of the cylindrical wall and no steam hole A rib that divides the surface is provided, the steam cylinder forms a through hole that penetrates vertically, the upper surface of this through hole is located on the surface without the steam hole, and is located above the lower end of the rib. Is.

Further, in order to achieve the second object, a bottomed reservoir is formed in the lower portion of the steam cylinder.

[0012]

According to the present invention, in the above structure, the steam generated in the pan during cooking passes through the through holes of the steam cylinder from the bottom to the top and reaches the surface without the steam holes on the lower surface of the outer lid, and the surface with the steam holes. And flows downward along a rib that divides the surface having no steam hole, reaches the lower end of the rib, and then is discharged to the outside of the cooker body through the steam hole of the outer lid.

[0013] Further, the foam-like bean that is generated from inside the pan during rice cooking passes through the through hole of the steam cylinder from the bottom to the top with the flow of steam, but the through hole and the outer lid after passing through the through hole are formed. Since the temperature of the surface without steam holes is lower than that in the pan, the bubbles are cooled in the middle of the through holes or on the surface of the outer lid without steam holes to become a liquid bed, which flows backward through the through holes from top to bottom. It reaches the inside of the pan and prevents spilling outside the cooker body.

When the temperature is kept warm, the upper surface of the through hole of the steam cylinder is located above the lower end of the rib separating the surface of the outer lid with the steam hole and the surface without the steam hole. Since heat is not easily transferred to the outside of the cooker body by using air as a medium, the temperature of the rice in the pan is not easily affected by the outside air and the temperature is easily maintained.

Furthermore, since it is located above the lower end of the rib that separates the surface of the outer lid that has steam holes from the surface that does not have steam holes, the moisture in the pan does not easily come out of the cooker body and the rice is dried. Can be prevented.

Further, since a bottomed reservoir is formed at the bottom of the steam cylinder, the amount of cooked rice in excess of that in the pan due to the fact that the amount of cooked rice was cooked more than specified, etc. Neba passes through the through hole of the steam cylinder with the flow of steam,
Even if the outer lid is cooled down to the surface without steam holes and becomes a liquid barb and flows downward along the outer wall of the through hole, it accumulates in the bottomed pool at the bottom of the steam cylinder. It is possible to prevent the steam from overflowing from the steam holes and spilling out of the cooker body.

【Example】

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIG.
-It demonstrates, referring FIG.

As shown in the drawing, the cooker main body 1 has a bottomed cylindrical pan 2 detachably installed therein. The lid 3 is rotatably supported by a shaft 4 on one side of an upper opening of the cooker body 1 and covers the upper opening. This lid 3
Is composed of an outer lid 5 made of synthetic resin which constitutes the upper surface, and a lid cover 6 made of aluminum which also constitutes the inner surface. The pan packing 7 is attached so as to be interposed between the outer cover cover 8 and the lid cover 6 which are fitted and fixed to the outer cover 5, and when the lid body 3 is closed, the pan packing 7 is completely attached to the upper opening portion of the pan 2. The circumference makes contact.

The tubular packing 9 is attached so as to be interposed between the steam hole 10 portion of the outer lid 5 and the steam hole 11 portion of the lid cover 6. A vapor cylinder 12 made of silicone rubber is detachably attached to the vapor hole 11 of the lid cover 6. A cylindrical wall 13 that abuts the packing 9 is provided around the steam hole 10 on the lower surface of the outer lid 5. Inside the circumference of the cylindrical wall 13, ribs 16 are provided to divide the surface 14 with the steam holes 10 and the surface 15 without the steam holes 10. The vapor cylinder 12 is formed with a through hole 17 penetrating up and down, and an upper surface 18 of the through hole 17 is located on a surface 15 of the outer lid where the vapor hole 10 is absent, and is higher than the lower end 19 of the rib 16 by H. It is located just above the distance. In addition, a hole 20 for draining water is provided in the lower portion of the steam cylinder 12,
The area of the hole 20 for draining water is 1 of the area of the through hole 17.
It is a small hole of about / 10.

In the above structure, the steam generated from inside the pan 2 during rice cooking passes through the through holes 17 of the steam cylinder 12 from the bottom to the top, and the steam holes 10 in the circumference of the cylindrical wall 13 on the lower surface of the outer lid 5 are generated. The steam hole 10 of the outer lid 5 reaches the non-existing surface 15 and flows downward along a rib 16 that divides the surface 14 having the steam hole 10 and the surface 15 having no steam hole 10 and reaches the lower end 19 of the rib 16. Is discharged to the outside of the cooker body 1.

[0021] Further, the foam-like bean bar generated from the inside of the pan 2 during cooking rice flows through the through hole 17 of the steam cylinder 12 together with the flow of steam.
Although it passes from the bottom to the top, the temperature of the through-hole 17 and the surface of the outer lid 5 after passing through the through-hole 17 without the steam hole 10 have a temperature of the pan 2
Since it is lower than the inside, the bubbles are cooled in the middle of the through hole 17 or on the surface 15 of the outer lid 5 where the steam hole 10 is not present, and become a liquid bed, and flow through the through hole 17 from the top to the bottom to the inside of the pot 2. Therefore, it prevents the spilling out of the cooker body 1.

When the temperature is kept warm, the upper surface 18 of the through hole 17 of the steam cylinder 12 and the surface 14 of the outer lid 5 on which the steam hole 10 is located and the steam hole 10
Since it is located above the lower end 19 of the rib 16 that divides the non-faced surface 15, the heat of the rice in the pan 2 is less likely to be transferred to the outside of the cooker body 1 using air as a medium. The temperature is not easily affected by the outside air, and the temperature is easily maintained.

Further, the upper surface 1 of the through hole 17 of the steam cylinder 12
Since 8 is located above the lower end 19 of the rib 16 that divides the surface 14 of the outer lid 5 with the steam holes 10 and the surface 15 without the steam holes 10, moisture in the pan 2 is also outside the cooker body 1 It is difficult to get out of the bowl and the rice can be prevented from drying.

(Second Embodiment) A second embodiment of the present invention will be described below with reference to FIG. The same components as those described in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. The difference from the first embodiment is the steam cylinder 1
A bottomed reservoir 21 is formed in the lower part of 2.

In the above structure, the amount of rice cooked is larger than the specified amount, and the excessive foam-like abacus generated from the inside of the pan 2 during the rice cook passes through the through hole 17 of the steam cylinder 12 and flows outside. When the surface of the lid 5 where the steam holes 10 are absent is cooled and becomes a liquid barb and flows downward along the outer wall of the through hole 17, it accumulates in the bottomed reservoir 21 at the bottom of the steam cylinder 12. Therefore, it is possible to prevent the steam from leaking from the steam holes 10 of the outer lid 5 and spilling out of the cooker body 1.

[0026]

As is apparent from the above description of the embodiments, according to the present invention, the steam cylinder serves as an alternative to the inner lid, and the cost of the steam cylinder (made of silicone) is lower than that of the inner lid (made of aluminum). Not only that, by removing the inner lid,
Since the inner lid holder shaft for providing the inner lid, the inner lid holder, and the number of work steps for fixing the inner lid holder shaft to the lid body are not necessary, the cost is further reduced. Also, since the steam cylinder is smaller than the inner lid and is made of a material that is unlikely to adhere to the sticks, it is easy to clean and easy to use. In addition, it is possible to provide a cooker capable of preventing the dryness of the rice cake from spilling out of the cooker main body during rice cooking and maintaining the temperature of the rice in the pan during heat retention to prevent drying.

Further, according to the present invention, since the bottomed reservoir is formed in the lower portion of the steam cylinder, it is possible to provide an effective means for preventing spillage of the stick on the cooker body during rice cooking.
