Description

  The present invention relates to a “cooking pan with a pan lid” which is placed on a heating device such as a gas stove or an electric heating stove and used to heat and cook various foods put into a lid body.

  Heat cooking that puts various ingredients in a pan body with an open bottom, closes the opening with a pan lid and places it on a heating device such as a gas stove or electric stove, and heats the bottom of the pan body to cook Pans are widely used.

  However, since the high-temperature combustion gas and high-temperature gas generated from the heating device during cooking are brought into contact with the outer circumference of the pan bottom and then rise along the outer circumference of the pan bottom and are dissipated in the air, the efficiency of heat conduction to the heated food in the pan Is extremely low, the heating cost is high, and a long cooking time is required.

  In addition, because it is heated on one side from the bottom of the pan, for example, when cooking in an empty pan body with lump or thick foods such as rice cakes and baking, the heating from the upper side is insufficient. In order to prevent this, the troublesome work of removing the lid from time to time and inverting it is necessary.

  There is a proposal of a pizza kiln shown in Patent Document 1 as a cooking pan that solves the above-mentioned difficulties, and this pizza kiln is placed on an inverted trapezoidal cap body on a “cooking pan for heating” on which a pizza material for cooking is placed. A structure that covers and sets the kiln, heats the lower surface of the saucer placed on the gas stove, and at the same time guides the combustion gas of the gas stove into the upper kiln and heats the food on the saucer on both the upper and lower sides Yes.

Registered Utility Model No. 3070975

  Patent Document 1 of the background art described above can improve the heating efficiency and shorten the heating time by effectively using the combustion gas by introducing the combustion gas of the gas stove into the upper kiln and heating the food on both sides. However, since the upper kiln has a simple inverted trapezoidal hollow shape, the hot gas flow introduced into the upper kiln is brought into contact with the flat ceiling plate to form an air flow form in the pot that flows non-uniformly downward. (The hot gas generated by the gas stove naturally flows in from the part where the resistance of the saucer is low and expels surplus gas inside, and does not flow uniformly from the peripheral edge of the saucer. Therefore, the surface of the pizza material, which is a plate-like ingredient, is not easily cooked uniformly.

  The present invention provides a cooking pan that eliminates the problems of the background art described above and further improves the cooking performance.

  The cooking pan of the present invention that solves the above technical problems is “a cooking pan comprising an upper opening pan body and a pan lid that is detachably set in the upper opening portion of the pan body. The pan lid has a lower edge opening having a diameter that is larger than the upper edge diameter of the pan body, and has a lid receiving portion projecting outwardly with an interval. In a state where the lid is placed on the lid receiving portion of the main body and covered, a shape in which a slit-like gas introduction path exists between the inner periphery of the lower edge and the outer periphery of the pan body, and the inner center of the head The structure is characterized by an inverted mountain-shaped airflow guide dispersion portion that disperses and guides the high-temperature airflow flowing in from the gas introduction path downward.

  That is, the cooking pan of the present invention having the above-described configuration is provided with a slit-like gas introduction path that naturally introduces a high-temperature airflow generated from the heating device of the pan body into the joining portion of the pan body and the pan lid, A hot and cold gas generated from a heating stove that naturally flows upward from the gas introduction path and flows into the lid by providing an inverted mountain-shaped high-temperature airflow guide dispersion part in the center inside with a pan lid shape of “medium-high shape” Is uniformly diffused downward by the air flow guide dispersion unit, and the cooked food in the pan body is made of the idea of “uniform heating of the surface and simultaneous heating of both upper and lower surfaces”.

  In the cooking pan of the present invention having the above-described configuration, the inflow of the high-temperature airflow into the gas introduction path is positively promoted at the lower edge of the pan lid with the intention of further improving the specific action by the idea. A mode in which a “gas introduction plate” is vertically installed is adopted.

  The cooking pan of the present invention having the above-described configuration has a substantially annular slit-like gas introduction path between the upper edge circumference of the pot body and the lower edge of the pot lid, so that the high temperature obtained by heating the bottom outer wall of the pot body Combustion gas and high-temperature gas naturally flow upward along the outer periphery of the pan body and actively naturally flow from the gas introduction path into the pan lid.

  And the pan lid that accepts its natural introduction has a medium-high shape and an airflow guide dispersion part that swells in an inverted mountain shape inside the center, so the naturally introduced high-temperature gas is guided to the inside of the pan lid and rises Then, the steady flow of the high temperature gas downstream that is led to the air flow guide dispersion unit and uniformly dispersed downstream is generated, and the excess air flow is pushed out from the gas introduction path and sequentially introduced. Sequentially alternate with the natural updraft and continue its uniformly distributed downstream action.

  Thus, the cooked food in the pan body is efficiently heated on both sides by the downward heating from the bottom of the pan with a heating stove or the like and the convection and radiation heating on the downstream side of the high temperature gas, and the downstream side of the high temperature gas is a uniformly dispersed flow. Therefore, the cooked food enjoys high-quality heating in which the upper side, the lower side, and the side periphery are uniformly heated.

  Due to the above heating mechanism, the finished cooked food can be cooked with high quality by making it extremely uniform and uniform. And while cooking time is shortened and efficient by the said double-sided heating, the troublesome operation | work, such as reversal of a heating cooking thing, is made unnecessary, and the heat cooking of the high thermal efficiency by the effective utilization of the high temperature waste gas of a heating source can be performed.

  A preferred embodiment will be described below.

  1 to 3, the cooking pan 1 of this embodiment has a flat bottom surface and a pan-shaped pan body 2 having an upper opening, and a pan that is detachably set in the upper opening of the pan main body 2. In the inner pot near the upper edge of the pot body 2, a mounting corner 11 is provided in which a heated object mounting plate 12 such as a wire mesh plate is detachably fitted in parallel with the bottom surface. .

  And this pan main body 2 has three protrusion-shaped lid receiving parts 4 which put "the outer peripheral part of the pan lid 3 on the upper edge circumference of the upper opening and cover the pan lid 3 on the pan main body 2" Are integrally projected outwardly at the three equal positions.

  And the pan lid 3 is formed in a substantially spherical wall shape having a middle and high height by a gently curved surface having a convex outer periphery, and the lower edge is placed on the three projecting lid receiving portions 4 of the pan body 2 so that the upper opening of the pan body 2 is opened. It can be detachably covered and set. And this pot lid 3 is set so that the inner diameter D2 of the lower edge circumference is larger than the upper edge outer diameter D1 of the pot body 2, and when it is set to cover the pot body 2, the outer circumference of the upper edge of the pot body 2 and the pot lid 3 The slit-shaped gas introduction path 5 is set to a structure that is secured along the circumference of the portion where the lid receiving portion 4 is not present.

  Furthermore, this pan lid 3 is provided with an airflow guide dispersion portion 6 swelled downward in an inverted mountain shape with a spherical wall shape at the center portion inside the top, and the “pan body that naturally flows from the gas introduction path 5” is provided. The high-temperature combustion gas / high-temperature gas H generated from the heating stove of No. 2 and flowing into the pan from the gas introduction path 5 is uniformly guided and dispersed downward by the airflow guide dispersion unit 6 to generate a downward flow. It is made up of.

  And the pot lid 3 of this embodiment is set to a gas introduction plate 7 that is extended vertically downward slightly except for joining to the lid receiving portion 4 of the pot body 2. It is configured to actively and efficiently support the supply of gas to the gas introduction path 5.

  In addition, the thing of this Example is "the upper edge outer diameter D1 of the pan body 2 = about 300 mm, the inner diameter D2 of the lower edge of the pan lid 3 = about 316 mm, the height H1 of the pan body 2 = about 40 mm, the pan The dimensions are such that the height H2 of the lid 3 is about 60 mm, the diameter D3 of the airflow guide dispersion unit 6 is about 100 mm, and the height H3 of the airflow guide dispersion unit 6 is about 20 mm. 9 is a handshake of the pan lid 3.

  The cooking pan 1 according to this embodiment (see FIG. 4) is suitable for “blank cooking” of a lump or flat cooked food 10 such as a grilled rice cake or pizza. At the same time that the cooked food 10 is placed on the wire mesh plate 12 fitted in the placing corner 11 and placed on a heating device such as a gas stove and heated, and the bottom of the pan body 2 is heated by the high-temperature frame 13 or the like of the heating device, The high-temperature combustion gas / high-temperature gas H generated by the frame 13 and naturally flowing up is naturally introduced from the gas introduction path 5 into the pan lid 3, and the cooked food 10 is heated by cooking both the upper and lower sides uniformly.

  The above cooking pan 1 has the above-mentioned specific action. For example, a lump “baked rice cake cooking product 10” is approximately half as short as a conventional heating pan from the bottom of a conventional pan. The whole can be cooked uniformly and with high quality. Then, the troublesome operation of removing the pan lid 3 during heating and rolling it to prevent “baking unevenness” is completely unnecessary.

  The plate-like pizza baked food can be cooked with good quality by making both the upper and lower surfaces uniform.
