[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, a pot-shaped cooker that can be used alone as a pot, and a lid-shaped cooker that can be used alone as a frying pan, and these cookers alone or these cookers and another housed inside thereof A combined cooker for cooking food inside with a cooking vessel or cooking utensil, wherein the pot-like cooker and the lid-like cooker have open end shapes that engage with each other, and are continuous with one inner peripheral edge of the opening. Alternatively, a step portion is provided discontinuously, and an engagement piece engaged with the inner peripheral surface of the opening from the step portion to the opening end is continuously or discontinuously provided on the other opening peripheral edge, and Since the step portion is formed with a gap for holding the peripheral portion of the another cooking container or the cooking utensil inside the composite cooking device, it is possible to obtain a cooking device capable of performing various cooking methods. Can be.
[0014]
That is, the pot-shaped cooker and the lid-shaped cooker can be used independently as a pot and a frying pan, and by combining these cookers, the appropriate weight of the lid-shaped cooker and the open ends that engage with each other can be obtained. Due to the water sealing effect of the shape, it is possible to cook with only the water content of the ingredients, it is possible to cook in a short time, it is possible to cook on the fire, etc. By combining with a cooking vessel or cooking utensil, it becomes possible to perform another heating cooking which cannot be performed by a conventional waterless cooking pot.
[0015]
Since the pot-shaped cooker and the lid-shaped cooker according to the present invention are expected to have a water-less cooking pot-like effect, the material is preferably made of a thick material having good heat conductivity. For example, aluminum and its alloys, iron, stainless steel and its alloys, and laminates of different kinds of metals having a thickness of 3 mm or more and 5 mm or less are selected. In addition, if the thickness is less than 3 mm, the heat generated when the bottom of the pot-shaped cooker is heated does not spread to the entire cooker, and the waterless cooking pot-like effect obtained by heating the whole cooker so as to wrap it cannot be expected. If the thickness is more than 5 mm, the weight of the entire cooker becomes too heavy and the handling is not easy.
[0016]
The shape of the pot-shaped cooker and the lid-shaped cooker in the present invention is not a problem as long as the shape is a so-called "pan" or "frying pan", even if its planar shape is circular, elliptical, rounded square, or the like. There is no. However, most of the heating stoves have circular flames. Therefore, it is preferable that the flat shape is circular, because heat unevenness is less likely to occur, and a good waterless cooking pot-like effect is expected. it can.
[0017]
The inner surfaces of the pot-shaped cooker and the lid-shaped cooker according to the present invention have no problem even if they are made of a metal material, but preferably are not easily scorched when covered with a fluororesin film, and are well-maintained. become. In addition, when combined with another cooking container or cooking utensil housed therein, there is an advantage by coating the inner surface with a fluororesin coating, which will be described in detail later.
[0018]
Another cooking container or cooking utensil stored inside the composite cooker according to the present invention is provided continuously or discontinuously at the opening inner peripheral portion of one of the pot-like cooker and the lid-like cooker. Another gap is formed by the gap formed between the stepped portion and the top of the engaging piece continuously or discontinuously protruding from the other opening edge of the pot-shaped cooker and the lid-shaped cooker. The periphery of the cooking vessel or utensil is held. This ensures that another cooking container or cooking utensil having a peripheral portion formed therein is held in the composite cooker.
[0019]
The cooking container according to the present invention includes a flange portion that is discontinuously engaged with the stepped portion in the circumferential direction, and a steam passage from the pot-shaped cooker to the lid-shaped cooker is provided on the outer peripheral portion of the cooking container by the flange portion. It is secured and the bottom of the cooking vessel is held apart from the bottom of the pan-shaped cooker. More specifically, each of the substantially rectangular four corners has a planar shape in which a flange portion that can be engaged with the step portion is formed, and the passage is formed by the substantially rectangular four sides and the inner wall of the cooker. The container to be formed is mentioned.
[0020]
That is, since the portions other than the four corner flanges are secured as steam passages from the pan-shaped cooker to the lid-shaped cooker, water is poured into the pan-shaped cooker so that the bottom surface of the cooking container is not immersed in the pan-shaped cooker. When the bottom of the pan-shaped cooker is heated with a stove or the like with the lid closed, the generated steam convects in the cooker through a passage between the circular wall surface of the cooker and the four sides of the cooking vessel. In addition, the temperature of the steam is hardly lowered due to good heat conduction in the entire cooker, and high-temperature steam (so-called dry steam) is caused to flow, so that even if the frozen food is thawed or heated, it is finished with a sticky taste.
[0021]
Further, if the inner surface of the cooking device, particularly the inner surface of the lid-shaped cooking device, is coated with a fluororesin film, even if the vapor condenses, small water droplets will not fall down on the ceiling surface. This is presumably because the water repellency of the fluororesin coating caused adjacent small water droplets to not reach each other and no water droplets to grow. Further, it is considered that heat is transmitted to the lid portion in response to the heating, and the water droplets on the ceiling surface evaporate together with the condensed water, and as a result, the water droplets on the ceiling surface do not fall. Further, water droplets condensed on the side wall portion flow down along the wall surface due to the water repellency of the fluororesin coating. Water sealing is performed on the water droplets flowing down and the opening where the lid-shaped cooker and the pot-shaped cooker engage. The steam generated inside eventually pushes up and escapes outward. At this time, the inside of the engaging opening is kept at a uniform high temperature state by the water sealing effect, and the effect of shortening the steaming time is also exhibited.
[0022]
In addition, the cooking container of the present invention preferably includes a plurality of handles fixed at axially symmetric positions of the peripheral edge portion, and when the handles cover the lid-shaped cooker, the handles come into contact with the inner top surface of the lid-shaped cooker. Since it has an unrestricted height, steam cooking is possible even when it is stored inside the cooker, and it is convenient to take out food when cooking is completed.
[0023]
The cooking utensil according to the present invention includes a peripheral portion that engages continuously or discontinuously in the circumferential direction of the stepped portion. Inside the peripheral portion, steam or a steam from the pot-shaped cooker to the lid-shaped cooker is provided. A perforated holding plate is provided for securing a passage for smoking and for holding the object to be cooked away from the bottom surface of the pot-shaped cooker. More specifically, a tool made of a net having a frame member which engages with a stepped portion on a peripheral edge portion is exemplified.
[0024]
That is, because of the net, it is secured as a passage for steam or smoke from the pot-like cooker to the lid-like cooker. Therefore, when water is poured into the bottom surface of one of the pan-shaped cooker and the lid-shaped cooker, the net on which the food is placed is placed and the other is covered, and heated with a stove or the like, the generated steam passes through the stitches and passes through the cooker. Convection inside. In addition, the temperature of the steam is hardly lowered due to good heat conduction, and high-temperature steam (so-called dry steam) is conducted throughout the cooker.
[0025]
In the case of simple smoking (hot smoking), place a chip for smoking on the bottom of the pan-shaped cooker, put a net with food on it, cover the cooker with a lid, and cook on a stove etc. Heat and smoke the chips to smoke and then smoke for 10-15 minutes while controlling the smoke. Further, if the inner surface of the cooking device, particularly the inner surface of the lid-shaped cooking device, is covered with a fluororesin coating, it is convenient to remove dirt or the like after smoking is finished.
[0026]
The lid according to the present invention includes an outer shape that is inserted into an opening inner peripheral surface from a step portion provided at an opening inner peripheral portion of one of the pot-shaped cooker and the lid-shaped cooker to an opening edge, A protruding piece that engages with the inside of an engaging piece that is continuously or discontinuously protruded from the other opening peripheral portion of the pot-shaped cooker or the lid-shaped cooker is formed continuously or discontinuously in the circumferential direction. Have been.
[0027]
Therefore, when each of the pot-shaped cooker and the lid-shaped cooker is used alone, the opening of any cooker can be covered. In addition, if the peripheral part mounted on the step part of the lid of the present invention is formed to be thinner than the gap formed between the step part and the top part of the engaging piece, the pot-shaped cooker and the lid-shaped It can also be used as an inner lid that covers between the cooker.
[0028]
These pot-like cookers, lid-like cookers, cooking containers, cooking utensils, and inner lids may be purchased as one pot set, and at least a pot-like cooker, a lid-like cooker, May be purchased as a set, and other cooking containers, cooking utensils, and inner lids may be separately purchased as options.
[0029]
In addition, another cooking container or cooking utensil stored therein includes a step portion provided continuously or discontinuously at an inner peripheral portion of one of the openings of the pot-shaped cooker and the lid-shaped cooker, and a pot. A configuration in which the peripheral portion is held by a gap formed between the top of an engaging piece continuously or discontinuously protruding from an opening peripheral portion of the other of the open cooker and the lid-like cooker. Anything is possible, and there is still room for improvement. Therefore, as long as the configuration of the peripheral portion is held in the gap, an improved cooking container or cooking utensil can be stored in the future, and it is possible to purchase these later.
