Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen-printed cookware panel. More specifically, the present invention relates to a cookware panel in which a panel surface having a protruding flange portion formed by burring is screen-printed.

[0002]

2. Description of the Related Art In a conventional cooking utensil such as a gas stove, a soup saucer is placed on a top plate in order to catch the broth that overflows from a cooking pot. However, sometimes the broth travels down the top plate and spills on the panel surface of the housing. If the squeeze spills, the squeeze may enter the inside of the gas control device (gas cock) through the gap between the operation rod and the panel opening hole of the cooker body through which the rod penetrates. In order to prevent this, as shown in FIG. 5, the panel a is subjected to a burring process, and a burring portion d having a protruding flange portion c is provided on the outer peripheral edge of the opening hole b. In addition, e and f are claws for fixing the panel a to the front plate of the main body. Such a panel is generally screen-printed for the purpose of rust prevention and decoration. Screen printing is done before pressing the panel and then
Press processing such as burring processing and bending processing for processing a panel into a predetermined shape was performed.

[0003]

However, in the conventional cooking appliance panel, since press working is performed after printing,
There is a problem that the printed surface is likely to be scratched during the pressing process and during the transportation of the panel assembly line after the pressing process.
Therefore, it is considered preferable to perform the screen printing after performing the press work, but it is difficult to reverse the order of the printing process and the pressing process because the panel has the burring portion. That is, when the order is reversed, it is conceivable to use a silk plate that avoids the burring portion, or divide the screen printing into a plurality of times. However, in any case, there is a problem that the number of printing processes increases. Therefore, an object of the present invention is to solve the above-mentioned problems of the conventional technique, and to provide a cooking appliance panel that does not scratch the printing surface and does not increase the number of printing steps.

[0004]

The inventors of the present invention have made extensive studies to solve the above-mentioned problems of the prior art. As a result, a recess is formed in the panel and the burring portion is provided in the recess. That is, by forming a recess so that the burring portion does not protrude from the smooth continuous surface of the panel, it is possible to perform screen printing on the panel metal plate surface after press working without any trouble. is there.

That is, according to the present invention, a burring process is performed to prevent the spillage of spills into the inside of the cooking utensil, and the burring part having a protruding flange part is provided on the outer peripheral edge of the burring hole by the processing. In the instrument panel,
A recess is formed around the burring portion, the height of the flange is lower than the depth of the recess, and the surface is screen-printed.

[0006]

According to the present invention (the invention according to claim 1), as described above, the flange portion of the burring portion does not protrude upward from the recess formed in the panel. Therefore, since there is no obstacle due to the burring portion on the surface of the panel to be screen-printed, it is necessary to perform screen-printing on a predetermined portion of the panel surface by one printing step using one printing plate You can Moreover, since it is possible to perform screen printing after pressing,
There is no risk of scratches on the printed surface of the panel. Claim 2
According to the invention of claim 1, since the surface other than the recess is screen-printed, the printing is finished beautifully without the recess. However, the surface other than the recess does not exclude the outer peripheral edge of the recess. Further, according to the invention of claim 3, since the metal plate after pressing is screen-printed, the printed surface of the panel is not scratched.

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described in detail below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is a main body of a cooking appliance provided with two burners for a gas stove. The main body 1 is formed of a metal plate having a U-shaped cross section and a front plate which form both sides and back of the cooking utensil, and a top plate 2 and a front panel 3 are attached to the main body 1 to form a housing of the cooking utensil To be done. A total of four legs 4 that support cooking utensils are attached to the corners of the bottom surface of the main body 1, and a connection tool 5 that connects to a gas source via a rubber tube or the like is provided on the back surface of the main body 1. The top plate 2 has two left and right openings 6 and 6 in the depression 2a, and a narrow hanging piece 2b bent downward is integrally provided on the periphery of the opening. Soup trays 7, 7 are detachably placed on the top plate 2 so as to cover the openings 6, 6. Gotoku 8,8 is placed on each soup saucer 7,7. Each soup tray 7 has an opening 7a at the center, and a burner cap (not shown) faces the opening 7a. On the front side of the front panel 3, two left and right burner instrument plug knobs 9, 9 are arranged. Each knob 9 is attached to one end of an operating rod 10 which penetrates the panel 3 and has its tip inserted into the gas control device. As is well known, ignition and extinction of the burner and adjustment of the fuel flow rate are performed by pressing and rotating the knob 9.

In FIG. 3, the front panel 3 includes an upper surface portion 3a having a bulging portion, an upper portion 3b protruding forward, an intermediate portion 3c gently inclined forward, a lower portion 3d inclined rearward, a lower surface portion 3e and a fixed portion. It is composed of a locking piece 3f. To assemble the front panel 3 to the main body, after inserting the claws provided on both front side end portions of the main body side plate into the holes of the mounting pieces bent backward from both side portions of the front panel 3, the upper surface portion 3a and the lower surface portion By caulking both side portions of 3e to the side plates, the front panel 3 is fixed to the cookware body 1. In addition, in the top plate 2, the hanging piece 2b on the front side is brought into contact with the upper portion 3b projecting forward, and the protrusion of the top board 2 is fitted into the burring portion of the side plate, and the entire hanging piece 2b is placed at the upper end of the cookware body. By being fitted to the portion, it is fixed to the cooking utensil body.

The panel of the present invention can be assembled to various cooking utensils. For example, end pieces (not shown) may be separately attached to both sides of the panel. In this case, both sides of the front panel 3 of the panel are shortened by the width of the end piece. On both sides of the panel, a plurality of burring portions are bored in the upper portion thereof, a plurality of holes are bored in the side piece bent rearward, and an inner bent portion is formed in the lower surface portion thereof. On the other hand, the upper part and the lower part of the end piece correspond to the upper part and the front side surface shape of the panel. In addition, the end piece is provided with claws at portions corresponding to the burring portion, the hole, and the inwardly bent portion formed in the panel. Then, the end pieces are fixed to both side portions of the panel by inserting these claws into the burring portion, the hole, and the inwardly bent portion, respectively.

Burring is applied to the front panel 3, and the burring portion 12 through which the operating rod 10 penetrates,
Twelve are provided. In addition, a hole 11 for fixing the gas control device is formed around the burring portion 12. The planar shape of the burring portion 12 is not limited to a circular shape, but may be a polygonal shape (for example, a quadrangle) or the like.
Any shape can be used as long as it corresponds to a cross-sectional shape of 0 and is arbitrary. The burring portion 12 includes a burring hole 13 and a projecting flange portion 14 formed on the outer peripheral edge of the burring hole 13. In this flange portion 14, the simmered juice that has overflowed from the soup saucer 7 travels through the top plate 2 and the upper portion 3b of the front panel and enters the cooking appliance (gas control device) through the gap between the operation rod 10 and the burring hole 13. It is provided in order to prevent this. A concave portion 15 is formed on the outer peripheral portion of each burring portion 12.
Are formed. The shape of the concave portion 15 is not limited to the circular shape, and generally corresponds to the shape of the knob 9, and may be a polygonal shape such as an ellipse or a hexagon. Also, the recess 1
Regarding the width of 5, the size of the back surface of the knob 9 is preferably about the same as or slightly smaller than that. Such a recess 15 can be formed, for example, by forming a step in the panel by drawing or pressing, but it is not always necessary to make the bottom surface flat or keep it parallel to the surrounding panel surface.

Screen printing P is applied to the surface of the panel 3 for the purpose of rust prevention and decoration, and for writing a print indicating the turning position of the knob 9. This screen printing P is usually performed while avoiding the concave portion 15, but it does not matter if the peripheral portion of the concave portion 15 in a region higher than the upper end surface of the flange portion 14 or a part thereof is printed. Silk screen printing is often used for screen printing on the surface of a metal plate. The material of the screen is not limited to silk, but synthetic fibers such as nylon and polyester, and fine metal wires such as stainless steel can be used. In order to print efficiently on the panel surface using the screen printing plate, the relationship between the height (h) of the flange portion 14 of the burring portion and the depth (d) of the recess 15 is
It is necessary to satisfy the condition h <d. If this condition h <d is satisfied, the screen printing plate will not come into contact with the flange portion 14, so that the screen printing P can be performed by one printing plate per panel in one printing step. . Therefore, the number of printing steps and the cost of the printing plate are reduced. The higher the flange portion 14 is, the burring portion 1
Although the strength around 2 is increased, it is preferable not to form the recess 15 deeper than necessary. Taking these points into consideration, it is preferable to set a ratio of the height of the flange portion 14 to the depth of the concave portion 15 with a margin so that the upper end of the flange portion 14 does not come close to the printing surface.

The cookware panel of the present invention can be manufactured, for example, by the following steps. That is, the metal plate is cut into a predetermined size by press working, and a predetermined place is bent. At this time, the recesses 15 are formed by subjecting the portions where the knobs 9 are arranged (two locations in this embodiment) to drawing. Next, the inside of the concave portion 15, for example, the central portion thereof is subjected to a burring process to provide the burring portion 12. After that, the target front panel 3 is manufactured by performing screen printing P on the panel surface other than the recess 15. Thus, since the screen printing is performed after the pressing process, the print surface of the front panel 3 is not scratched.
Moreover, since it is not necessary to press the plate material for the panel according to the printing specifications, and the management man-hours in the pressing process are reduced, the management of the pressing process becomes easy. In addition, the presence of a plurality of recesses 15 in the burring portion 12 increases the number of drawn portions, and consequently improves the strength of the front panel 3.

Further, the present invention will be described with reference to another example of cooking equipment. The cooking utensil shown in FIG. 4 is different from that shown in FIGS. 1 and 2 mainly in that a grill function is added, and a duplicate description will be omitted. In FIG. 4, a grill door 21 with a peep window is provided at the center of the front side of the cookware body 20.
Is provided so that it can be pulled out together with the grill net and the water pan. A central opening is further formed in the recess of the top plate 22, and an upper edge of a grill exhaust port cover 23 mounted above the grill burner projects from the opening. Front panels 24a and 24b are attached to the left and right of the grill door 21. On the front side of the front right panel 24a, a right stove burner device plug knob 25a and a grill burner device plug knob 25b are arranged. On the front side of the front left panel 24b, a left stove burner instrument plug knob 25c is arranged. Each of the knobs 25a to 25c includes the panels 24a, 24.
The distal end portion is attached to one end of an operation rod which penetrates b and is inserted into the gas control device. The burring portions 12, 12 are arranged side by side on the front right panel 24a, and the front left panel 24b
The burring portion 12 is provided in the. Similar to the above-described front panel 3, the concave portion 15 is formed on the outer peripheral portion of each burring portion 12, and the screen printing P is applied to the surface of each panel 24a, 24b excluding the concave portion 15.

The cookware panel of the present invention is provided with one or a plurality of burring portions by burring processing, and a concave portion deeper than the height of the burring portions is formed around the burring portion. The panel in which the concave portion is formed around the burring portion may be integrally molded as shown in FIG. 1 or may be divided into a plurality as shown in FIG. 4 (A). In the present invention, such a panel is screen-printed. Further, the same applies to the case of a divided panel, but particularly in the case of an integrally molded panel, as shown in FIG. 3, it is preferable to form all curved portions on the front surface side of the panel by drawing. Compared to the panel formed by bending, the surface formed by drawing is curved smoothly, so
In combination with the fact that there are no obstacles on the printing surface that interfere with printing, screen printing can be performed easily. Although the gas stove is described in this embodiment,
The present invention in which screen printing is performed on the surface of a panel that has been subjected to burring processing can be applied to, for example, the operating portion of an oven or the top plate of a stove. Further, it is effective to dispose the panel on the operation portion on the front side of the cooking utensil, because the concave portion which is usually the non-printing surface is covered with, for example, a knob.

[0015]

According to the present invention, since the concave portion is formed around the burring portion so that the flange portion of the burring portion does not project upward from the printing surface of the panel, the screen printing plate is not flanged during the printing process. There is no such thing as hitting a department. Therefore, it is not necessary to use a printing plate that avoids the burring portion or to perform screen printing separately in multiple times, and it is possible to perform screen printing on the panel surface by one printing step with one printing plate. Therefore, the number of printing steps and the cost of the printing plate can be reduced as compared with the conventional printing of the cookware panel. Moreover, since it is possible to perform screen printing after press working, it is easy to manage the press process and the printed surface is not scratched. Further, since the recesses can be formed by drawing, the strength of the panel is improved in that case, and the strength is further improved when there are a plurality of recesses. According to the second aspect of the present invention, screen printing is performed on the panel surface excluding the concave portions, and the printing is finished beautifully. Further, according to the invention of claim 3, since the press working is performed before the printing process, the printed surface of the panel is not scratched.
