The mounting structure of the upper peripheral portion of the tray body with respect to the ring body is provided with a support protrusion on the upper surface of the ring body or at a predetermined interval on the lower surface of the upper peripheral edge. The upper peripheral edge is placed and locked on the ring body via the support protrusion, so that the upper peripheral edge is placed and locked in a floating state without surface contact locking on the ring body. The inside of the pan body between the upper peripheral edge of the tray body and the ring body Configured to levitation gap passing is formed, in which the steam inside the pot body is arranged to flow out to the back side of the pot lid through the flying gap from substantially the entire periphery of the tray member. Further, the ring body is configured in a plate shape, and the plate-shaped ring body is configured such that the inner peripheral portion is positioned lower than the outer peripheral portion via the stepped portion. That is, the ring body has upper and lower step portions, and is configured to have a step over the entire circumference below the upper peripheral edge portion of the tray body.

  According to this configuration, the steam uniformly hits the dish mounting portion of the tray body, and the dish can be finished very efficiently and satisfactorily without unevenness.

  However, in this patent document 1, in addition to the pan body, the tray body, and the pan lid body, in addition to the material cost for providing the ring body, a plurality of support protrusions are provided on the separately provided ring body and manufactured. Higher costs and higher costs.

  Therefore, the applicant has proposed Japanese Patent No. 3084260 (Patent Document 2) that can be manufactured very easily without the cost of manufacturing as compared with Patent Document 1.

  Briefly explaining this Patent Document 2, a pan body provided with a stepped portion on the inner peripheral surface of the upper opening peripheral edge, and a locking portion provided on the inner peripheral surface below the stepped portion, and the pan main body inner peripheral surface A tray body that locks the upper peripheral edge portion to the locking portion so as to pass through a gap, and is housed and disposed in the pan body; A steam cooking pan composed of a pan lid for closing and opening the opening, wherein the locking structure of the tray body with respect to the locking portion of the pan body has a predetermined interval on the inner peripheral surface of the pan body below the stepped portion. A plurality of locking projections projecting inward are provided to form the locking portion, and the upper peripheral edge of the tray body is placed and locked on the plurality of locking projections. The upper peripheral edge position excluding the place communicates with the inside of the pan body between the upper peripheral edge portion of the tray body and the inner peripheral surface of the pan body. It is configured so that a gap is formed, and the steam in the pan body flows out from the substantially entire circumference of the tray body through the gap to the back side of the pan lid body and flows into the tray body, A support projection that can contact the peripheral edge of the pan lid with a predetermined interval is provided on the step, and when the peripheral edge of the pan lid is placed on the support protrusion, the peripheral edge of the pan lid and the step A floating gap communicating with the inside of the pan body is formed between them, and the peripheral portion of the pan lid body is in a floating state at a position excluding the placement locking portion.

  That is, a support projection is provided on the pan body, and a projection for placing the pan lid and a projection for placing the tray body are provided simply by pressing a predetermined position on the outer peripheral surface of the pan body by pressing. Therefore, as compared with Patent Document 1, it does not take time for manufacturing, and the number of parts is small, so that it can be configured very easily and at a low manufacturing cost.

Japanese Patent No. 30695530 Japanese Patent No. 3084260

  However, in the said patent document 2, in the place except a support protrusion part, the vapor | steam which is heated at the bottom part of a pan main body and goes up hits directly the back surface (lower surface) of a pan lid body, without going around the upper peripheral part of a tray body. The steam that hits the back of the pan lid flows to the center of the pan lid along the back, and then descends at the center and flows into the food tray in the tray. Compared to the above-mentioned Patent Document 1 that wraps around the upper peripheral edge of the body, there has been a slight shift in the steaming speed between the central portion and the peripheral portion of the dish placing portion. In addition, most of the steam that is guided to the center of the pan lid by being guided by the pan lid rises to the center of the pan lid while being cooled by the pan lid that is always in contact with the outside air. It could not be said that it was used efficiently.

  Further, in Patent Document 2, when the internal pressure in the pan body rises and the steam is discharged to the outside of the pan body, a part of the steam is separated from the inner peripheral surface of the pan body and the upper peripheral portion of the tray body. Through the gap between the two, directly hit the inner wall of the pan lid, change the direction toward the peripheral edge of the pan lid, hit the inner peripheral wall of the upper opening of the pan body and be discharged to the outside of the pan body However, compared with the above-mentioned Patent Document 1 having a step over the entire periphery of the upper peripheral edge of the tray body, the steam is exhausted vigorously and sometimes causes spillage.

  Further, in Patent Document 2, when the upper peripheral edge of the tray body is locked to the locking protrusion for locking the upper peripheral edge, the locking protrusion of the tray as in the embodiment in Patent Document 2 is used. If the number is small, the upper peripheral edge of the tray body may not be properly placed on the locking projection, and the tray body may be inclined, and it is necessary to place the tray body carefully and accurately when placing the tray body. There was also room for improvement in stability. In addition, if the number of the locking projections is increased, if the upper peripheral edge of the tray body is fitted below the locking protrusion, the protrusion may be an obstacle even if the upper peripheral edge is lifted up. Therefore, it is necessary to pull out the device once and then mount it again. In addition, production costs will increase.

  In view of the problems of the conventional steam cooking pan, the present invention is a steam cooking pan that is less expensive than Patent Document 1 by a configuration that does not use a ring body, and is a dish placed on a tray body. Steam spreads all over the material and can be steamed up to a very good state quickly, and when the internal pressure rises, the steam is discharged smoothly and it is very difficult to spill, and the tray can be placed smoothly. The object is to provide a steam cooking pot with excellent stability.

  The gist of the present invention will be described with reference to the accompanying drawings.

  A steam cooking pot comprising a pot body 1, a tray body 2 accommodated in the pot body 1, and a pot lid body 3 that closes an upper opening of the pot body 1, Two upper and lower stepped portions 4 are provided on the entire inner peripheral surface of the upper opening, and a plurality of tray bodies are mounted on the upper surface of the lower stepped portion 5 of the stepped portion 4 at a predetermined interval in the circumferential direction of the lower stepped portion 5. The tray body 2 is accommodated in the pan body 1 by projecting the placement projection 7 and placing the upper peripheral edge 9 of the tray body 2 on the plurality of tray body placement projections 7. The tray body floating gap 13 communicating with the inside of the pan body 1 is formed between the upper peripheral edge portion 9 and the upper surface of the lower step portion 5 at a position excluding the placement portion. The peripheral wall 11 between the steps located between the lower step part 5 and the upper step part 6 of the part 4 is provided with a plurality of troughs at predetermined intervals in the circumferential direction of the peripheral wall 11 between the steps. -Protruding portions 12 for stopping the body positioning and setting the outer diameter of the upper peripheral edge 9 of the tray body 2 to be smaller than the inner diameter of the peripheral wall 11 between the steps, By placing the upper peripheral edge 9 of the tray body 2 on the placement protrusion 7, the upper peripheral edge 9 is positioned by the plurality of tray body positioning protrusions 12, and at positions other than the position where the position is stopped. A steam circulation gap 14 connected to the tray body floating gap 13 is formed between the upper peripheral edge portion 9 and the peripheral wall 11 between the steps, and the inside of the pan body 1 is passed through the vapor circulation gap 14. Steam is configured to flow out from substantially the entire circumference of the tray body 2 to the back surface side of the pan lid body 3 and to flow into the tray body 2, and the upper step portion is formed on the upper surface of the upper step portion 6 of the step portion 4. A plurality of pan lid mounting projections 8 projecting at predetermined intervals in the circumferential direction of the The pan lid body 3 closes the upper opening of the pan body 1 by placing the peripheral edge of the pan lid body 3 on the pot lid body projection 8 and the position excluding this placement location. The pan lid floating gap 15 is formed between the peripheral edge of the pan lid 3 and the upper surface of the upper stage 6 so as to communicate with the steam circulation gap 14. The diameter dimension is set to be smaller than the inner diameter dimension of the upper opening of the pan body 1 located above the upper stage portion 6, and the peripheral edge of the pot lid body 3 is placed on the plurality of pot lid body mounting projections 8. The steam discharge gap 16 communicating with the pot lid floating gap 15 is formed between the peripheral edge of the pot lid 3 and the upper opening of the pan body 1 by placing the portion. Each of the tray body mounting projections 7, each of the tray body positioning projections 12, and each of the pan lid body mounting projections 8 are integrally connected in a straight line. The steam cooking pot is characterized in that it is provided as a continuous protrusion 10 having a shape extending from the upper surface of the upper step portion 6 to the upper surface of the lower step portion 5.

  Since the present invention is configured as described above, it is a steam cooking pot that is less costly than Patent Document 1 by a configuration that does not use a ring body, and steam spreads evenly over foods placed on a tray body. It can be steamed up to a very good state quickly, and when the internal pressure rises, the steam is discharged smoothly and extremely hard to spill, and the tray can be placed smoothly, and the placement stability is excellent. It will be possible to provide a steam cooking pot.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  For example, a predetermined amount of water is placed in the pan body 1 and the food is placed on the food placing portion 17 where the food on the tray body 2 is placed. 5 is placed on a tray body placing projection 7 projecting from the upper surface of 5, and the peripheral edge of the pan lid body 3 is placed on a pan lid placing projection 8 projecting from the upper surface of the upper stage 6. When heated, the steam generated in the pan body 1 passes through the tray body floating gap 13 between the upper peripheral edge portion 9 of the tray body 2 and the upper surface of the lower step portion 5, and the tray body positioning projection 12 A dish placing portion for the tray body which is provided by positioning the upper peripheral edge portion 9 of the body 2 and is ejected from a steam flow gap 14 located between the peripheral wall 11 between the steps and the upper peripheral edge portion 9 of the tray body 2. It will flow into 17. At this time, the steam is a tray body floating gap 13 provided on substantially the entire circumference of the upper peripheral edge 9 of the tray body 2 (a position excluding the tray body mounting projection 7 and the tray body positioning projection 12). And the steam circulation gap 14, the steam is ejected from substantially the entire circumference of the upper peripheral edge 9 of the tray body 2, and thus heat is uniformly transmitted in the circumferential direction of the dish placing portion 17, Steam is sprayed evenly on the right dish and the left dish equidistant from the center of the dish placing portion, and the steam is well steamed.

  Further, at this time, the steam passes the tray body floating gap 13 between the lower surface of the upper peripheral edge portion 9 of the tray body 2 and the upper surface of the lower step portion 5, for example, outward, and then strikes the peripheral wall 11 between the steps to change the flow direction. The steam passing through the steam circulation gap 14 between the peripheral wall 11 between the steps and the upper peripheral edge 9 is changed while inwardly passing, so that the steam when passing through the steam circulation gap 14 wraps around the inside of the pan body 1. In addition, since the wraparound angle varies depending on the angle at which the steam enters the tray body floating gap 13, it moves to any location from the center to the outer periphery of the dish placing portion 17 of the tray body 2. Steam will also drop to the placed food, steam will be sprayed evenly on the food in the center of the food placing part 17 and the food in the outer periphery and steamed well. Become.

  That is, in the present invention, the steam is satisfactorily applied at any position that is equidistant from the center of the dish placing portion 17, and at any position from the center to the outer peripheral portion of the dish placing portion 17. Since the configuration is such that the steam can be satisfactorily applied, the food can be steamed well at all locations of the food mounting portion 17.

  Further, unlike the case of Patent Document 2 in which most of the heated steam flows along the back surface of the pan lid 3, heat loss is unlikely to occur, so that the high-temperature steam reliably acts on the food and heat efficiency. It will steam well and speedily.

  When the steam pressure rises more than necessary due to heating, the steam is naturally discharged out of the pan body 1 from the pan lid floating gap 15 between the upper stage portion 6 and the peripheral edge of the pan lid body 3 and blown out. Can be prevented.

  Also, the tray body mounting projection 7, the pan lid body mounting projection 8, and the tray body positioning projection 12 which are integrally formed in a straight line on the stepped portion 4 to form the continuous projection 10 are as follows. , Continuous tray body floating gap 13, steam circulation gap 14. Since the pan lid floating gap 15 and the steam discharge gap 16 are all arranged at the same position, the tray floating float 13, the steam circulation gap 14, and the pot lid body other than the position of the linear continuous projection 10. The levitation gap 15 and the steam discharge gap 16 are communication gaps that do not have protrusions on the way, and therefore, air flow is less likely to be disturbed when the steam rises, and the tray body passes through the tray levitation gap 13 and the steam circulation gap 14. When the steam flows smoothly into 2 and the internal pressure of the pan body 1 rises more than necessary, the steam of the pan body 1 is smoothly discharged, so that the structure is extremely difficult to blow.

  Furthermore, in the present invention, when the steam pressure rises and is discharged out of the pan body 1, the steam rising from the bottom of the pan body 1 hits the tray body 2, and the upper peripheral portion 9 and the lower step portion 5 of the tray body 2. Passing through the tray floating gap 13 between the two, passing through the steam flow gap 14 and hitting the peripheral wall 11 between the steps, changing the direction upward, then hitting the back surface of the pot lid 3 and passing through the pot lid floating gap 15 Since it passes through the discharge gap 16 and hits the inner peripheral surface of the upper opening of the pan body 1, the momentum of the jet of steam is weakened each time. In comparison, it becomes a safer steam cooking pot.

  Further, the present invention is different from Document 2 in which the stepped portion 7 is not provided under the tray body mounting projection 7. For example, when the same tray body 2 as that in Document 2 is used, the tray body of the tray body 2 is used. The inner peripheral surface of the pan body 1 approaches the outer peripheral surface of the tray body 2 by a width equal to the width of the lower step portion 5 provided below the mounting projection portion 7 in the entire circumferential direction, and the outer peripheral surface of the tray body 2 Since the distance between the pan body 1 and the inner peripheral surface of the pan body 1 is reduced, play between the tray body 2 and the inner peripheral surface of the pan body 1 is reduced, and the pan body 1 is lowered from the stove together with the pan body 1 after cooking. When the pan is moved for reasons such as changing the stove during cooking, the tray body 2 rises from the tray body mounting projection 7 and the upper peripheral edge 9 is above the tray body locking projection 12. Even if it is swung to the left and right by moving, the inner peripheral surface of the pan body 1 Will be obtained, the tray member 2 so that the deviation Nikuku high mounting 置安 qualitative from the mounting position is obtained.

  In addition, since the tray body mounting projection 7 is provided on the upper surface of the lower stage portion 5, the lower stage portion 5 can be placed in the tray body even when the tray body 2 is placed in the pan body 1 filled with steam. 2 is easy to set as a mark of the mounting position, and mounting becomes easy.

  Therefore, even when making liquid dishes such as tea fumigation and pudding, or dishes that are already nicely arranged on a platter, liquids are not spilled during cooking, and the dishes are less likely to be biased. Is.

  Further, since the tray body placing projection 7, the tray body positioning projection 12 and the pan lid placing projection 8 are integrally formed as the continuous projection 10, the projections are respectively provided. From the structure in which the parts are scattered, it is relatively easy to clean and can be maintained hygienically.

  Furthermore, the linear continuous projections 10 constituting the tray body placement projections 7, the tray body locking projections 12 and the pan lid placement projections 8 are, for example, It can be provided simultaneously and integrally by pressing the outer peripheral surface of the stepped portion 4 of the pan body 1 inward, and can be realized by a simple method, so that the mass productivity is increased and the cost is reduced. It can be produced. Moreover, since accessories, such as a ring body, are not required like patent document 1, since material cost and manufacturing cost can be reduced, a steam cooking pan can be produced still more cheaply.
