Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a cantilever wok with strong pot and handle attachment parts.

[0002]

[Prior art]

 Conventional cantilever woks are roughly classified into the following three methods. (1) The pan body and the part that will be the handle are separately molded from the iron plate material, and the part that will become the pan body is formed into a pan body with a predetermined curved shape by pressing, and the part that will be the handle is rolled into a cylindrical shape. The handle is welded to the pot body by a connecting member that is curved in a convex shape toward the upper side. (2) The pan body and the part that will be the handle are integrally molded from an iron plate, and the curved surface of the pan body is formed by pressing, and the part that is the handle is rolled into a cylindrical shape and connected to the pan body. Is curved in a convex shape toward the upper side to give strength. (3) As in the case of (2) above, the part of the iron plate material that is integrally molded into the pot body is formed into a predetermined curved surface shape by pressing, and then the side surface middle part of the pot body is stamped out. When it is made somewhat thinner, and the part that becomes the handle is processed in the same way as (2) above.

[0003]

[Problems to be solved by the device]

 However, in the cantilever wok made by the method of (1) above, the thickness of the whole wok body becomes uniform, so the weight of the wok body becomes heavier and the hand when cooking. The burden on you will increase. Moreover, in the strength test of the handle when a load twice as much as the capacity of the pan body was repeatedly applied with the handle fixed, cracks occurred at both ends of the handle attachment after about 4,000 times of repetition. , The strength of the handle was very weak. In addition, in the cantilever wok made by the method of (2), it is difficult to integrally mold the part that becomes the pan body and the part that becomes the handle from the iron plate, Since the material is likely to be wasted, the material cost is high. In addition, the weight of the pan body is heavy and the burden on the hand is large, as in the case of (1) above. However, the strength test of the handle was improved to about 8,000 times, but the strength of the handle was not strong enough to satisfy the requirements. In addition, in the cantilever wok made by the method of (3), compared to the cases of (1) and (2), the side part of the pan body is stretched and thinned to the extent that the pan is thin. Since the weight of the main body is lighter, the burden on the hands during cooking can be lightened by that much, but when the same repeated test as described in (1) above is performed, cracks occur at both ends of the handle attachment. The number of repetitions up to that time increased to about 10,000, but it could not be said that the strength was still sufficiently strengthened as compared with the case of (2) above. The present invention has been made in view of these circumstances, and it is easy to mold the pan body and the handle, there is little loss during molding, and the weight of the pan body is reduced to reduce the burden on the hand. In addition, the purpose of the invention is to provide a cantilever wok with which the bottom of the pan body is less likely to be punctured and the strength at both ends of the handle attachment can be increased.

[0004]

[Means for Solving the Problems]

 The present invention has been made in order to achieve the above-mentioned object, and in a cantilever wok in which a pot body and a handle are separately formed and integrally joined by welding, the pot body is made from a steel plate material by spatula drawing. The handle is fixed to the inner surface of the pan by welding, and the lower tip of the handle is fixed to the handle. This is a cantilevered wok characterized in that the connecting member extending to the main body side is welded to the reinforcing member welded to the outer peripheral surface of the pan main body or is integrally formed with the reinforcing member. When it is desired to effectively increase the strength of the handle attachment part with a small amount of material, the reinforcement member should have a thickness approximately equal to or greater than the thickness of the pot body to be welded, and the length along the circumferential direction of the pot body. May be formed to be longer than the circumferential length of the fan-shaped portion welded to the inner surface of the pan body.

[0005]

[Embodiment of device]

 Hereinafter, embodiments according to the present invention will be described with reference to the drawings. 1 to 5 show an embodiment of the present invention. In a cantilever wok, a pot body 1 and a handle 2 are separately formed, and then both are integrally joined by welding. . The pot main body 1 is formed into a predetermined curved shape by subjecting a circular iron plate material having a thickness of 1.2 mm to a spatula drawing process. To make the pan body 1 by spatula drawing, keep the thickness of the pan bottom approximately equal to 1.2 mm of the thickness of the iron plate, gradually reduce the thickness of the side surface of the pan, and gradually reduce the thickness at the top end. The thickness of the pot main body 1 is made to be lighter than that in the case where the entire thickness is approximately uniform by pressing. In addition, in order to reduce the weight of the pan body 1, the number of steps required for processing is reduced as compared with the case of performing a striking process in the middle part of the side surface of the pan body 1 formed by pressing. is there.

The handle 2 is formed by winding an iron plate material in a cylindrical shape, but may be formed of a metal material having a smaller thermal conductivity than the iron plate material. The attachment of the handle 2 is performed on both the inner surface and the outer peripheral surface of the pan body 1. Of these, the attachment to the inner surface of the pan body 1 is performed by welding with the fan-shaped portion 2a formed so as to project from the upper end of the handle 2 and bent downward so as to overlap with the inner surface of the pan body 1. It is fixed. The pot body 2 was attached to the outer peripheral surface by fixing the rectangular reinforcing member 3 in the circumferential direction of the outer peripheral surface on the upper end side of the pot body 2 by using spot welding and ordinary welding together. This is performed by welding the tip of the connecting member 4 fixed to the reinforcing member 3 so as to close the space formed in the lower tip of the handle 2. The connection member 4 is fixed by welding the reinforcement member 3 with the tip end abutting against the reinforcement member 3 or by overlapping with the reinforcement member 3 or by welding to both the reinforcement member 3 and the pan body 1. However, it may be performed by other means. As the reinforcing member 3, when the size of the pan body 1 is about 36 cm in diameter, the length is 18 cm, the width is 2 cm, and the thickness is about the same as or more than the thickness of the part to be welded. A thickness of about 1.2 mm, for example, is used, but other sizes may be used.

According to the cantilevered wok having the structure shown in this embodiment, the pan body 1 is kept in a state where the thickness of the bottom portion of the pan body 1 is kept approximately the same as the thickness of the die-cast iron plate material. The thickness of the side of the pan should be continuously thinned from the bottom of the pan to the top, and the strength of the mounting part of the handle 2 should be strengthened sufficiently so that cracks will not occur even after repeated 20,000 times. it can. FIG. 6 shows another embodiment of the present invention, in which the reinforcing member 3 and the connecting member 4 in the above embodiment are integrally formed. In the case of this configuration, the number of parts can be reduced as compared with the above-mentioned embodiment, the welding process of the reinforcing member 3 and the connecting member 4 can be eliminated, the working efficiency can be improved, and the production cost can be reduced.

[Effect of device]

 According to the present invention, the following excellent effects can be obtained. In the cantilever wok according to claim 1, since the part serving as the pan body and the part serving as the handle are separately molded, the mold is not only easy to mold, but also at the time of molding. The material loss of can be reduced. In addition, the pot body can be made by spatula drawing to keep the thickness of the pot bottom part almost the same as the iron plate material, and the thickness of the side part can be made thinner toward the upper side, so the strength of the pot bottom part is kept strong. In this state, the weight of the pan body can be lightened to reduce the burden on the hands during cooking. Moreover, since the handle is attached to the pan body by welding to the upper part of the side of the pan body whose strength is strengthened by the reinforcing member, the strength of the handle attachment part is significantly strengthened by using a small amount of material. You can extend the life of your wok. In the cantilevered wok according to claim 2, the reinforcing member has a thickness that is substantially equal to or greater than the thickness of the pot body of the portion to be welded, and the length of the pot body along the circumferential direction is the pot body. Since it is formed longer than the circumferential length of the fan-shaped part that is welded to the inner surface of the body, even if the size or thickness of the pan body changes, it is extremely easy to change the size and thickness of the reinforcing member. As a result, the life of the cantilever wok can be extended.
