DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a staple cooking oven, a side cooking oven, a cooker, etc. on a truck or a trailer stand, and cooking the food by using time while traveling outdoors or toward a destination. The present invention relates to a recirculation type rice cooker for an outdoor cooking car, which is capable of performing the above-mentioned steps.

[0002]

2. Description of the Related Art Conventionally, boiling water as described in Japanese Utility Model Publication No. 63-40174, for example, is used to boil a large amount of rice at once and
The boiled juice is scattered around the lid due to the vibration of the car body and burns the cooker without sticking to the surface of the furnace or other parts. It is a reflux type for outdoor cooking carts that cooks cooked rice in a stable and good condition and can cook delicious rice safely, sanitarily, and can easily perform cooking and cleaning work after both. Rice cookers are known.

[0003]

However, the above rice cooker for an outdoor cooking car has no small holes on the peripheral side wall of the inner pot and its four corners for refluxing steam and hot water, and thus cooks rice. Is performed over the entire area surrounding the inner pot, and is performed only in the downward direction, and the reflux in the lateral direction is not performed at all through the peripheral side wall and the four corners. As a result, there is a problem that not only the cooking takes a long time but also the cooked rice at the four corners of the inner pot becomes uneven.

[0010] The present invention comprises the above constitution,
When cooking rice, rice and water are charged as shown in FIG. 1, and the handle mounting plate 8c of the inner pot 8 is attached to the net cover 18 as shown in FIG.
When the burner 2 is ignited by placing the rod-shaped handle 8g and the universal joint 8e on the mesh lid 18 and igniting the burner 2, the water boils and countless steam is formed in the water. Bubbles are formed, and at the same time as the water increases due to expansion, steam accumulates at the bottom. At that pressure, hot water whose specific gravity has become lighter due to the steam bubbles is removed from each of the hot water passages 10, 11 between the outer kettle 7 and the inner kettles 8, 8. It is pushed up and falls on rice. Then, the falling hot water passes between the rice grains, returns to the lower skirt portion 9 through a partition plate 13 having a large number of small holes 15 and a bottom portion 14 having a large number of small holes 16, and is again pushed up. It is something that is being done. At this time, a part of the hot water is also circulated in the lateral direction by the peripheral side wall 8a of the inner pot 8 and a required number of small holes 30 provided at required positions across four corners of the peripheral side wall 8a. As the hot water circulates in this way, the rice changes into rice, and finally the hot water disappears, and the rice cooking is completed.

[0011]

According to the present invention, it is possible to boil rice using the time during traveling, and of course, boiled boiling water (simmered soup) and excess steam other than those necessary for boiling are removed from the lid. From the boil-in spill inflow chamber with a blocking valve provided at the top of the inner surface, it is discharged to the outside of the furnace through the boil-spill outflow gutter provided to protrude on the upper surface of one side of the lid, and can be cooked in a constantly stable state, and Also, after the rice grains are cooked, the inner pot is immediately turned into a food can by holding the rod-shaped handle, and it can be easily carried to any place to quickly supply hot cooked rice. Time and, of course, it is very suitable for cooking of disasters, etc., but in particular, in the present invention, a required number of small holes are provided in a required portion straddling the inner side wall of the inner pot and four corners of the peripheral side portion. By providing, reflux of steam and hot water As a result of being able to perform not only in the upper and lower directions of the inner pot, but also in the horizontal direction, the cooking time of rice is shorter than in the past, and the uniform cooking state that could not be solved conventionally That is, there is an effect that the cooked rice at the four corners (each corner) of the inner pot can be cooked deliciously in a uniform state with other portions.
