Description

Kitchen vessel and its manufacturing method {COOKING VESSEL AND THEREOF MANUFACTURING METHOD}

The present invention relates to a kitchen vessel and a method for manufacturing the same, and more particularly, a kitchen vessel capable of maximizing productivity by maximizing productivity, preventing defects and ensuring a long life by swiftly and mass production through ease of workability. And to a method for producing the same.

In general, kitchen containers can be divided into a grilling pan for grilling beef, pork, duck or fish, or a hot pot for boiling stew, or a pot for boiling ramen or broth. Metal such as aluminum iron or stainless steel is produced by injection or die casting.

Kitchen containers made by injection or die casting are made of a single layer and utilize heating heat as direct heat, which causes a problem that meat or fish cannot be grilled or cooked slowly, but the outer surface is easily burned or pressed.

In order to overcome this phenomenon. Publication No. 1998-043111 discloses a roasting pan which is not pressed or burned.

1 is a perspective view illustrating a previously disclosed roasting pan, and FIG. 2 is a cross-sectional view illustrating a previously disclosed roasting pan.

As shown in FIGS. 1 and 2, the roast pan is uniformly embedded with a layer of ocher powder 4 between double metal plates 1 and 2 in the form of a pot lid made of brass or copper, The upper metal plate 1 at the moment when the ocher powder 4 is evenly distributed around by the centrifugal force while holding and rotating the double metal plates 1 and 2 in the jig through the through holes 5 of the riveted double metal plates 1 and 2. The periphery (3) of the can be wrapped around the periphery (3 ') of the bottom metal plate (2) is made of a configuration such that the ocher layer 4 is evenly distributed between the surface and the bottom double metal plate (1, 2).

By the way, since the pre-disclosed roasting pan is made by filling the ocher powder 4 between the upper metal plate 1 and the lower metal plate 2 and filling it with centrifugal force, the work is so difficult that the productivity is greatly reduced. have.

On the other hand, the roasting pan made of a metal body has excellent thermal conductivity so that food can be easily cooked, but the food is easily burned by the direct heat of the metal body itself, and when the heating source (heater) is removed, it cools down immediately for a long time. It has the disadvantage of not having it.

In order to overcome this phenomenon, a technology that incorporates a heat storage body that can retain heat for a long time, such as charcoal or loess, has been developed in kitchen containers of the same field as a baking pan. There is a type for screwing a metal body to a metal body, a type for pressing and pressing a metal body and a metal body with a second heat storage body interposed therebetween, and a type of die casting a metal body with a third heat storage body interposed therebetween.

Prior art type 1 (screw coupling type) in the kitchen vessel field

Figure 3 is a cross-sectional view showing a heating vessel for the kitchen notice (2006.05.03. Announcement, Utility Model Registration No. 415451).

The pre-announced kitchen heating vessel shown in FIG. 3 has a bottom surface 11 that is convexly rounded toward the center to provide an under space 11a and a ridge 12 having a screw groove 12a at the bottom and a circular shape. The container 10 having the circle supporter 13 protruding into the bottom plate, the under plate 20 and the underspace 11a fitted with the circle supporter 13 and having a through hole C corresponding to the screw groove 12a. And the char plate 30 is filled between the under plate 20, and through the through hole (C) consists of a configuration including a bolt 40 is fastened to the screw groove (12a).

Such a kitchen heating container has a structure in which the bottom surface 11 on which the food is cooked substantially does not directly contact the heating source and receives heating heat indirectly, so that food is not easily burned and charcoal particles 30 are in the off state of the heating source. Its efficiency can be recognized in terms of its ability to continuously utilize heating heat through its heat storage function for a long time.

However, the pre-announced kitchen heating container can not fill the charcoal particles 30 filled between the under space 11a and the under plate 20 in a quantitative manner during the assembling operation, but cannot be filled in abundantly or excessively. There is a disadvantage in greatly reducing the, in particular in the gap (T) between the under plate 20 and the circle supporter 13 is fitted in a state in which the coal particles 30 are fitted to the problem that the outside air or moisture is easily absorbed Giving birth.
