By the way, as in Patent Document 1 and Patent Document 2, the technique of providing a saucer and a return port in the pan body or providing a needle valve in the pan lid tends to be complicated and expensive. In addition, when boiled juice or the like is clogged or adhered to the return port or the needle valve, there is a problem that care is troublesome. In addition, as in Patent Document 3, when the pan lid itself is made into a net, the inside of the pan body can not be sealed, although the risk of the broth spurting out can be prevented. It could not be shortened much, and there was a limit to reducing the amount of gas used.
Furthermore, in the technique of providing a steam vent hole whose opening degree can be adjusted in the knob as in Patent Document 4, when the broth comes out from the gap between the pan body and the pan lid, the broth is around the range around the pan. There was a problem that the cooking environment could not be kept clean due to spilling and dirt.

  Therefore, the present invention can be configured at a low cost by adopting an extremely simple configuration, can save energy by shortening boiling time and boiling time, is effective for preventing spilled and spilled boiling, and is well-maintained. The purpose is to provide a simple cooking and cooking pot.

  In order to achieve the above object, the present invention provides an apron that surrounds the pot lid by extending the periphery of the opening of the pot body outwardly from the periphery of the pot lid in a rice cooking / cooking pan equipped with a pan body and a pot lid. In addition, the pan lid has a cross-sectional arch shape that is curved so that the height of the central knob portion is the highest and decreases toward the periphery, and steam or the like is applied to a predetermined portion of the pan lid. A discharge hole for discharging is provided, and a steam discharge member made of an elastic material in close contact with the upper surface of the pan lid is provided on the knob portion so as to cover the upper surface of the discharge hole of the pan lid, and the lower surface of the discharge member for steam, etc. In addition, a groove groove is formed along the radial direction so as to communicate with the discharge hole of the pan lid and discharge the steam discharged from the discharge hole from the peripheral edge of the discharge member such as steam. .

And in boiling, when the pressure in the pan body increases, steam and broth etc. that have passed through the discharge hole of the pan lid will be drained to the upper surface of the pan lid through the concave groove of the steam discharge member. For example, the steam or the like is returned to the inside of the pot body through the gap between the pot body and the pot lid without going out of the pot by the apron portion surrounding the pot lid. At this time, even when relatively heavy boiled juice or moisture other than light steam is included as the discharged steam, the boiled juice or moisture is discharged obliquely downward along the arch shape of the pan lid, Will not scatter.
Even when the pressure in the pan body rises above a predetermined value, the steam discharge member is an elastic material, so the steam discharge member is elastically deformed by the pressure of the steam discharged from the pan lid discharge hole. A gap is generated between the pan lid and the discharge member such as steam, so that excessive pressure is released, and there is no problem that the pan lid rattles.
In addition, since cooking is performed with the pot lid closed, the cooking time can be shortened and energy saving can be achieved.
Furthermore, since the configuration is simple, it can be configured at low cost.

  At this time, in addition to providing a plurality of outlet holes for the pan lid, a plurality of concave grooves on the steam discharge member are also provided, and by rotating the steam discharge member around the central axis, the discharge amount of steam and the like can be adjusted. In this case, it is possible to discharge steam or the like by an appropriate amount according to the situation, which is more preferable.

In the present invention, the steam discharge member can be easily disassembled.
Thus, by making it possible to easily remove the discharge member such as steam, for example, even when boiled juice is clogged in the concave groove of the steam discharge member, it can be easily maintained.

In rice cooking and cooking pots with a pan body and pan lid, the periphery of the opening of the pan body is an apron part surrounding the pan lid, and the shape of the pan lid is made into a cross-sectional arch shape, and at the predetermined place of this pan lid A discharge hole for discharging steam or the like is provided, and a steam discharge member made of an elastic material that is in close contact with the upper surface of the pan lid is provided at the knob portion so as to cover the upper surface of the discharge hole of the pan lid. Is able to reliably prevent splashing of broth and shorten cooking time by forming a concave groove for discharging steam discharged from the discharge hole of the pan lid from the peripheral edge of the discharge member such as steam. Thus, energy saving can be achieved, and the configuration can be reduced more simply with a simple configuration.
At this time, if there are a plurality of discharge holes for the pan lid and a plurality of concave grooves on the steam discharge member, the discharge amount of steam etc. can be adjusted by rotating the steam discharge member around the central axis. More preferable.
Further, if the discharge member such as steam can be easily disassembled, it is convenient because it can be easily cared for even when, for example, the concave groove of the steam discharge member is clogged.

It is a whole perspective view which shows an example of the cooking pot for boiled rice and boiled cooking which concerns on this invention. It is a longitudinal cross-sectional view of the cooking rice and cooking pot. It is explanatory drawing which looked at the pan lid from the back side. It is explanatory drawing of the grooved groove | channel of discharge members, such as steam. It is explanatory drawing which shows the relationship between the discharge hole of a pan lid at the time of adjusting discharge | emission amounts, such as a vapor | steam, and the grooved groove | channel of discharge members, such as a vapor | steam.

Embodiments of the rice cooking and cooking pots according to the present invention will be described with reference to the accompanying drawings.
The cooking pot for boiled rice and boiled cooking according to the present invention can save energy by shortening the cooking time and boiling time, and can be configured at low cost for cooking rice and boiled cooking pots effective for preventing spilled boiled and scattered broth. Has been.

  As shown in FIG. 1 and FIG. 2, an example of the main cooking / boiled cooking pan 1 includes a metal pan body 2 and a pan lid 3, and the pan body 2 is located near the upper opening. 3 includes an apron portion 2e that extends outward from the periphery of 3 and surrounds the periphery of the pan lid 3, and the apron portion 2e is once bent in a direction in which the diameter is increased outward and then bent inward again. It is in the form.

As shown in FIG. 2, the pan lid 3 is formed in an arch shape that is curved so that the height of the central knob 4 portion is the highest and the height decreases toward the periphery, and a screw rod is provided at the upper center portion. 6 is fixed by welding or the like, and this screw rod 6 is inserted through an insertion hole 5h of a steam discharge member 5 to be described later with a slight gap, and from there, the screw hole 4n of the knob 4 is inserted into the screw rod 6 By screwing to the upper part, the lower surface of the steam discharge member 5 is brought into close contact with the upper surface of the pan lid 3, and at the same time, the steam discharge member 5 is prevented from coming out.
In the present embodiment, the knob 4 and the discharge member 5 such as steam are configured separately, but they may be configured integrally.

  Further, as shown in FIG. 3, a plurality of discharge holes 7 are provided at predetermined positions of the pan lid 3, and the positions of the discharge holes 7 are determined from the diameter of the steam discharge member 5 described below. By setting the position closer to the center so as to be within a small range, all the discharge holes 7 can be covered by the discharge member 5 such as steam.

  The steam discharge member 5 is made of an elastic material such as heat resistant rubber, and as shown in FIG. 4, a plurality of concave grooves 8 are carved on the lower surface side (contact surface with the upper surface of the pan lid 3). The concave groove 8 is formed along the radial direction of the steam discharge member 5 and opens toward the peripheral edge.

  For this reason, when the concave groove 8 is located in the upper part of the discharge hole 7 of the pan lid 3, the steam in the pan body 2 passes through the discharge hole 7 and the concave groove 8 as shown in FIG. In this case, relatively light steam scatters upward, and relatively heavy water, broth, etc. fall obliquely downward along the cross-sectional arch shape of the pan lid 3, It comes to return in the pot main body 2 from the clearance gap between the pan lid 3 and the pan main body 2, and the malfunction that a broth etc. scatters to the circumference | surroundings can be suppressed. At this time, since the shape of the upper end of the apron portion 2e is curved inward, there is little possibility that the soup will spill out.

By the way, if the relative positional relationship between the discharge hole 7 of the pan lid 3 and the groove 8 of the steam discharge member 5 is changed, the discharge amount of steam or the like can be adjusted.
That is, as shown in FIG. 5A, when the steam discharge member 5 is rotated around the screw rod 6 and adjusted so that the groove 8 is located above the maximum number of discharge holes 7, the fully opened state is obtained. As shown in FIG. 5 (c), the discharge amount can be maximized by adjusting the concave groove 8 to be positioned above the minimum number of discharge holes 7, as shown in FIG. As shown in FIG. 5B, the discharge amount can be reduced to an intermediate level by setting the intermediate position between the two. Further, as shown in FIG. 5 (d), if it is turned to a position where all the discharge holes 7 are closed, the discharge amount of steam or the like can be made zero.
At this time, a scale or the like for knowing the positions of full open, middle open, small open, and full close is displayed at predetermined locations on the pan lid 3 and the steam discharge member 5.
Of course, when the knob 4 and the steam discharge member 5 are integrated, it is more convenient because the steam discharge member 5 can be rotated by rotating the knob 4.

  And, the amount of exhaust gas such as steam can be adjusted appropriately according to the type of ingredients, the type of dish, etc., so that more delicious dishes can be cooked efficiently.

In addition to cooking such as curry and stewed dishes, such cooking pot 1 is widely used as a pot for cooking rice, for example, or for cooking udon, buckwheat or pasta. Can be used for cooking.

  At this time, even when the pressure in the pan body 2 is increased to a predetermined value or more and the pressure of the steam discharged from the discharge hole 7 of the pan lid 3 is increased, the steam discharge member 5 is made of heat-resistant rubber, which is an elastic material. For this reason, the steam discharge member 5 is elastically deformed, and a gap is generated between the pan lid 3 and the steam discharge member 5 so that excessive pressure is released. For this reason, there is no malfunction that the pan lid 3 rattles.

  Further, when the knob 4 is loosened and the knob 4 is removed, the steam discharge member 5 can be easily removed, so that it can be disassembled and removed even when the groove 8 is clogged with foreign matter, for example. Easy to clean.

In addition, this invention is not limited to the above embodiments. What has substantially the same configuration as the matters described in the claims of the present invention and exhibits the same operational effects belongs to the technical scope of the present invention.
For example, the positions and number of the concave grooves 8 and the discharge holes 7 are examples.

  It is effective in preventing the spilling of boiled spills and broths, and the cooking time can be shortened to save energy. For this reason, it is expected to be widely used as cooking utensils in homes and the like.
