Description

  The present invention relates to a cooking plate such as a hot plate, a table grill or an electric grill.

  A cooking device such as a hot plate has a case body that forms an outer shell and has legs at the bottom, a perforated cooking plate that is provided at the top of the case body and cooks an object to be cooked such as meat, and the cooking plate. A heater for heating the cooking plate, a water tray for receiving gravy or oil, and a heat shield member provided below the heater for safe and comfortable cooking on a table or the like. The food to be cooked is placed on the cooking plate and cooked.

  The hot plate has the members and structure as described above, and even if the meat is cooked on the table, the table does not become hot, and the meat juice or oil from the meat flows down and smoke is generated. It is not used, and after use it can be easily removed and removed, so it is used in many homes.

  Conventionally, a cooking plate is shape | molded by die-casting so that it may be described in the following patent document 1, for example. In this casting, molten aluminum is poured from the gate using an injection piston, and the aluminum injected with high pressure is poured into the necessary part, but the excess poured aluminum is stored in the overflow part, Generation of nests during casting can be prevented.

  By the way, what has a some convex rib and long hole in the upper surface is known for the cooking plate. However, the above-mentioned conventional example does not relate the direction of the convex ribs or long holes on the upper surface of the cooking plate and the position of the gate of the mold when casting the cooking plate. If the pouring gate is provided in a direction perpendicular to the longitudinal direction of the long hole, the flow of the hot water becomes poor, short shots (underfilling) are likely to occur, and nests or bubbles are likely to be generated.

  In order to eliminate such harmful effects, it is conceivable to enlarge the overflow part or use a vacuum apparatus. However, increasing the overflow part increases the amount of wasted material, which increases the material cost. In addition, when a vacuum apparatus is used, a new problem that production cost increases.

  FIG. 1 is a sectional view of the whole cooking device (a sectional view taken along line AA in FIG. 3), FIGS. 2 and 3 are perspective views and plan views of the cooking plate, and FIG. The schematic sectional drawing of the metal mold | die equivalent to a line direction is shown. The cooking device includes a hot plate, a table grill, an electric grill, and the like. In the following, the hot plate will be described as an example.

  As shown in FIG. 1, the hot plate 10 includes a case body 20, a heat shield member 25, a heater 30 supported by the heat shield member 25, and a cooking plate 40 disposed above the heater 30.

  The case main body 20 is a resin member, and constitutes the outline of the hot plate 10. The case main body 20 has a substantially rectangular shape in plan view, and has a plurality of legs 21 for mounting on a table or the like at the bottom thereof. An upper opening 22 and a bottom opening 23 are formed in part of the upper surface and the lower surface.

  The heat shield member 25 is a substantially dish-shaped member having a substantially rectangular shape in plan view, which is formed by integrally forming a metallic thin plate by pressing, and is housed in the case body 20. The surface of the heat shield member 25 is subjected to reflection and heat insulation treatment to prevent the heat of the heater 30 from being transmitted to the case body 20.

  Further, a water receiving tray recess 25 a is provided at the center of the heat shield member 25. And the water receiving tray 27 is set to this recessed part 25a for water receiving trays. The water receiving tray 27 is a metal container, which is filled with water and set in the water receiving tray recess 25a. The position where the water tray 27 is set is directly below a through hole 44 of the cooking plate 40 described later, and receives gravy, oil, etc. flowing down from the through hole 44.

  Furthermore, a plurality of heater supports 28 for supporting a heater 30 to be described later are attached to the heat shield member 25. The upper end of the heater support 28 is substantially U-shaped with an upper opening, and supports the heater 30 from below and from the side.

  The heater 30 has, for example, a substantially heart shape or Y shape in plan view, and a sheathed heater is used. More specifically, as shown by a broken line in FIG. 3, the inner portion surrounds the mortar-shaped region 42 of the cooking plate 40 in a substantially circular shape, and the outer portion thereof is a plan view passing through the flat region 41. It has a substantially heart shape and is supported by the plurality of heater supports 28. The heater 30 is electrically connected to a known temperature controller.

  The heater 30 has a structure in which, for example, a coiled heating wire is passed through a metal pipe, heat-resistant inorganic insulating powder such as magnesia is packed in order to prevent contact between the pipe and the heating wire, and both ends of the metal pipe are sealed. It is what is usually called an incoloy heater. Since the heater 30 has such a structure, the metal pipe is insulated, and even if it touches the metal pipe, there is no electric shock. However, it is not particularly necessary to use a sheathed heater, and other heaters may be used.

  The cooking plate 40 is made of thick aluminum die casting and is a substantially rectangular member in plan view similar to the case main body 20, and includes a flat plate region 41 and a mortar-shaped region 42, and a boundary between both regions 41, 42. A partition rib 43 that is circular and protrudes upward is formed. In addition, the curved surface S1 as shown in FIG. 5 is formed in the root part of the division rib 43, and while making the flow of gravy and oil etc. smooth, the flow of the hot water at the time of casting is made smooth.

  The flat region 41 is a horizontal region formed on the outer periphery of the cooking plate 40 and is mainly used for baking vegetables. This region is partitioned from the mortar-shaped region 42 by the circular partition ribs 43 so that vegetables or the like are not easily dropped into the mortar-shaped region 42.

  The mortar-shaped region 42 is a circular mortar-shaped region formed in the center of the cooking plate 40 and descending toward the center, and is mainly used for grilling meat. This region is partitioned from the plate-like region 41 by the circular partition ribs 43, and the intrusion into the plate-like region 41 such as gravy and oil is prevented.

  In the mortar-shaped region 42, a first convex rib group R1, a second convex rib group R2, and a third convex rib group R3 are formed, and a circular through hole 44 is formed in the center. Is done. The through-hole 44 has a diameter that is approximately ¼ of the diameter of the mortar-shaped region 42, and can discharge meat juice, oil, and the like at an early stage.

  The first convex rib group R1 includes a plurality of, for example, six first convex ribs 45. These first convex ribs 45 are equivalent to the convex ribs of the present invention, and are all linear ribs having substantially the same length and substantially the same cross section, and are substantially parallel from one to the other through holes 44. It is provided over the entire mortar-shaped region 42 in the radial direction. In this case, the top of the portion of the mortar-shaped region 42 is slightly inclined downward, and the top of the portion on the through hole 44 is horizontal, but may be horizontal throughout.

  As shown in FIGS. 1 to 3, the first convex rib 45 on the through hole 44 divides one through hole 44 into a plurality, in this case, seven long hole openings 44 a. The The opening 44a corresponds to the long hole of the present invention, and as shown in FIG. 3, the longitudinal direction thereof is the same as the longitudinal direction of the first convex rib 45 corresponding to the convex rib of the present invention.

  Meat juice, oil, and the like are discharged to the water tray 27 through these seven openings 44a. Thus, since each 1st convex rib 45 is bridged across the through-hole 44 and meat etc. can be baked on this 1st convex rib 45, in the whole mortar-shaped area | region 42, it is. Meat can be cooked.

  Further, as shown in FIG. 5, the first convex rib 45 not positioned on the through hole 44 is formed with an arcuate or curved curved surface S <b> 1 at its root portion 45 a, and its tip corner portion. An arcuate or curved curved surface S2 is integrally formed in 45b at the time of casting. The curved surfaces S1 and S2 are formed by keeping the mold part forming the first convex rib 45 in such a shape, thereby making the flow of hot water better during casting.

  The curved surface S1 is not formed in the root portion 45a of the first convex rib 45 located on the through hole 44, and the root portion 45a of the first convex rib 45 is not located on the through hole 44. The width becomes shorter. Therefore, when hot water flows in a direction orthogonal to the first convex rib 45, short shots, nests or bubbles are likely to occur.

  The second convex rib group R2 includes a plurality of, for example, 21 second convex ribs 46. These second convex ribs 46 are shorter in the outer direction, both have substantially the same cross-section and extend in parallel or substantially in parallel, and their outer ends form a circular arc shape as a whole. Is linear as a whole, and has a generally comb shape in plan view.

  And although the 2nd convex rib group R2 is provided in the form orthogonal to the said 1st convex rib group R1, it does not cross | intersect the 1st convex rib group R1. That is, the inner end that forms a straight line as a whole does not extend to the through hole 44, and when meat or the like is baked in the second convex rib group R 2, And is discharged to the water receiving tray 27 through the outermost opening 44a. The second convex rib 46 may be provided with curved surfaces S1 and S2 similar to the first convex rib 45.

  The third convex rib group R3 is substantially the same as the second convex rib group R2 provided symmetrically on the opposite side to the second convex rib group R2 across the first convex rib group R1. The same shape. That is, a plurality of, for example, 21 third convex ribs 47 are formed. These third convex ribs 47 are shorter in the outer direction, all have substantially the same cross section and extend in parallel or substantially in parallel, and their outer ends form a circular arc shape as a whole, and the inner end Is linear as a whole, and has a generally comb shape in plan view.

  The third convex rib group R3 is provided symmetrically with the second convex rib group R2 in a form orthogonal to the first convex rib group R1, but the first convex rib group There is no crossing with R1. That is, the inner end that forms a straight line as a whole does not extend to the through-hole 44, and when meat or the like is baked with the third convex rib group R 3, the gravy and oil are between the third convex ribs 47. And is discharged to the water receiving tray 27 through the outermost opening 44a. The third convex rib 47 may be provided with curved surfaces S1 and S2 similar to the first convex rib 45.

  FIG. 6 shows another cooking plate 50. The cooking plate 50 is made of thick aluminum die-casting and is a substantially rectangular member in plan view similar to the case body 20 and has a flat plate region 51 and a convex rib region 52.

  The flat area 51 is a horizontal area formed on the outer periphery of the cooking plate 50 and is mainly used for baking vegetables. The convex rib area 52 is an area having a rectangular shape in plan view formed at the center of the cooking plate 50 and is mainly used for grilling meat.

  In the convex rib region 52, a plurality of convex ribs 53 corresponding to the convex ribs of the present invention are formed. The convex ribs 53 are linear ribs having substantially the same length and substantially the same cross section, and are provided substantially in parallel with a predetermined interval.

  And as shown in FIG. 6, between the adjacent convex ribs 53, the some long hole 54 corresponded to the long hole of this invention is provided. The longitudinal direction of the long hole 54 is the same as the longitudinal direction of the convex rib 53 corresponding to the convex rib of the present invention.

  And if meat etc. are baked in the convex rib area | region 52, gravy, oil, etc. will be discharged | emitted from these long holes 54 to the water tray which is not shown in figure. The convex rib 53 is formed with curved surfaces as shown in FIG. 5 at its root and tip corners to improve the flow of hot water during casting.

  FIG. 4 shows an outline of a mold that is a manufacturing apparatus for casting a cooking plate. 4 corresponds to the cross-sectional view taken along the line BB of FIG. 3 and the cross-sectional view taken along the line CC of FIG. 6, and shows a horizontal arrangement. The mold includes a fixed mold 61 and a movable mold 62. The fixed mold 61 has a shape on the bottom surface side of the cooking plates 40, 50, and the movable mold 62 has a shape on the upper surface side of the cooking plates 40, 50. FIG. As shown in FIG. 2, an inner space 63 corresponding to the outer shape of the cooking plates 40, 50 is formed at the center of both molds 61, 62.

  A pouring gate 64 is formed at one end of the internal space 63, and an overflow portion 65 is formed at the end opposite to the pouring gate 64. Then, when the aluminum melted from the gate 64 is press-fitted using the injection piston as indicated by the arrow, the poured aluminum fills the internal space 63, and excess molten aluminum is stored in the overflow portion 65. Is done. After natural cooling after pouring, the mold 60 is broken and the cooking plates 40 and 50 formed in the internal space 63 are taken out and used.

  In this case, in the cooking plate 40 of FIG. 3, the gate 64 is provided on one end side in the longitudinal direction of the first convex rib 45 and the opening 44 a, and the overflow portion 65 is the first convex shape opposite to the gate 64. In the cooking plate 40 of FIG. 6, the gate 64 is provided on one end side in the longitudinal direction of the convex rib 53 and the long hole 54. The overflow portion 65 is provided on the other end side in the longitudinal direction of the convex rib 53 and the long hole 54 on the side opposite to the gate 64.

  By providing the gate 64 and the overflow portion 65 in a straight line at the above-described position, the poured die-cast aluminum flows along the first convex rib 45 and the opening 44a, or the convex rib 53 and the long hole 54. Therefore, there is little resistance and the flow becomes smooth. As a result, the die cast aluminum fills the internal space 63 in a short time without occurrence of short shots, nests or bubbles. Therefore, it is not necessary to pour die-cast aluminum more than necessary, and the size of the overflow portion 65 can be reduced.

  Further, by providing the overflow portion 65 so as to face the gate 64, the flow of the die-cast aluminum becomes smoother. Further, as shown in FIG. 5, the first convex rib 45 and the convex rib 53 have a root portion 45a and a tip corner portion 45b having curved surfaces S1 and S2 such as arc shapes, so that the flow of hot water is more Become smooth.

  Further, in the case of FIG. 3, the curved surface S <b> 1 is formed on the first convex rib 45 positioned on the through hole 44, or in the case of FIG. 6, the root portion 45 a of the convex rib 53 on both sides of the long hole 54. Is not formed, and the width of the root portion is shortened, but by providing the gate 64 at the above-described position, the flow of hot water to that portion can be made smooth.

  If the gate 64 is provided in a direction orthogonal to the first convex rib 45 and the opening 44a or the convex rib 53 and the long hole 54, the first convex rib 45 and the opening 44a or the convex rib 53 and The long hole 54 becomes a large resistance, and the pouring time becomes long, and short shots, nests or bubbles are likely to be generated. For example, when a vacuum apparatus is used, the cost is increased and the overflow portion 65 needs to be enlarged. There is.

  As shown in FIGS. 3 and 6, the gate 64 and the overflow portion 65 are provided on the long sides 40 a and 50 a of the cooking plates 40 and 50. Therefore, compared with what is provided in the short side 40b, 50b, the whole magnitude | size of the metal mold | die 60 can be reduced in size.

  3 has a second convex rib 46 and a third convex rib 47, which are orthogonal to the gate 64, but shorter in length than the first convex rib 45, Because there is so little resistance, the hot water is enough.

  And these 2nd convex rib 46 and 3rd convex rib 47 make height high the area | region where hot water flows easily, and makes height low the area | region where hot water does not flow easily. That is, when the pouring gate 64 is provided at a position as shown in FIG. 3, the hot water flow is faster in the vicinity of the central through hole 44, and the hot water flow is slower in the region away from the through hole 44 in the left-right direction.

  As shown in FIG. 1, the second convex rib 46 and the third convex rib 47 are formed such that the through hole 44 side is high and the opposite side is low. Therefore, hot water of a fast flow is poured into the high part, so that it is filled easily. Low water is poured into the low part, but since the height is low, it is filled easily. That is, the second convex rib 46 and the third convex rib 47 are also poured in a short time without occurrence of short shots, nests or bubbles.

  The invention of the present application is not limited to the configuration of the above embodiment, and it is needless to say that the design can be appropriately changed without departing from the gist of the invention.
