Description

  The present invention relates to a hot plate in a roaster, which is provided between a heat source and a wire mesh or the like on which food to be heated is placed, and has good thermal efficiency.

  Conventionally, for example, when roasting in a roasted meat dish, an iron plate is placed above a burner installed at the lower center of the roaster, and raw meat is placed on the heated iron plate and baked.

  However, the part of the iron plate that is directly above the flame of the burner is hot, but the other part is not heated and the temperature is lower than the central part. While the meat was easy to burn, it was difficult to bake evenly because the meat in the surrounding position away from the center was not yet lit.

  Therefore, a heat plate is provided between the heat source and a wire mesh or the like on which the food to be heated is placed so that heat can be evenly distributed by this heat plate so that it can be baked evenly, and heat efficiency is improved. A board has been proposed.

  In order to distribute heat evenly, a metal hot plate is formed with a circular cross section in the thickness direction of the main surface to form a number of through-holes, and a part of the opening edge of the flame port is integrated with the main surface. It is assumed that there are claw-like small pieces that are connected to each other and face the convex side with respect to the main surface, and a plurality of small pieces are integrally formed by cutting lines that do not close to the main surface.

In the above-mentioned prior art documents, it is assumed that a large number of flame openings are formed in the main surface of the hot plate, small pieces are provided in the flame openings, and all of the small pieces face the upper surface side.
For this reason, there is a problem in that the exhaust becomes too good, and a lot of flame and hot air escapes from the flame outlet near the center, and the flame and hot air are not sufficiently transmitted to the peripheral edge, and the hot plate is not heated evenly.

In addition, gravy falling from the upper metal mesh etc. will be received by the hot plate, but a small piece will obstruct the flow of the gravy and prevent it from falling from the flame outlet and burn on the hot plate There is also.
Furthermore, it is pointed out that it is difficult to clean dirt on the hot plate, such as gravy.

  Accordingly, the present invention is intended to solve these problems, and to provide a roaster hot plate that can be heated up to the peripheral edge of the hot plate, exhausts in the hot plate without trouble, and is easy to clean. It is.

  The hot plate for roaster according to claim 1 of the present invention is a hot plate having a central portion that swells in a dome shape and a side wall that is suspended from a peripheral end portion, and a large number of through holes except for the vicinity of the dome-shaped central top portion. The base portion is connected to the end face of the through hole, and the tip portion has a tongue piece protruding to the front side or the back side so as to cover the through hole. To do.

  According to a second aspect of the present invention, in the hot plate for roaster according to the first aspect, the through-hole having a tongue piece projecting on the front surface side is disposed on the inner side near the central top portion, and the tongue piece projecting on the back surface side is disposed outside the through hole. In addition, a through-hole having an outer periphery is disposed, and only the through-hole is formed in the outermost area near the end portion.

  According to a third aspect of the present invention, in the hot plate for roaster according to the first or second aspect, the base portion of the tongue piece is connected to the end surface on the central top side of the through hole, and the tip portion protrudes outward in the direction of the peripheral end portion. It is characterized by being.

  According to a fourth aspect of the present invention, in the roaster hot plate according to any one of the first to third aspects, the angle between the protruding tongue piece and the through-hole surface is such that the through-hole is positioned outside in the peripheral end direction. It is characterized by becoming larger.

  According to a fifth aspect of the present invention, in the hot plate for roaster according to any one of the first to fourth aspects, the surface of the hot plate is provided with a single continuous notch, and a straight line connecting the ends is used as a folding line. A through-hole is formed by bending toward the side or the back side, and the bent portion is formed as a protruding tongue piece.

  According to the first aspect of the present invention, since the central portion of the hot plate swells in a dome shape and the side wall is suspended from the peripheral end portion, the flame and hot air rising from a heat source such as a burner from the lower center of the hot plate It hits the top of the dome-shaped central part, descends along the surrounding arcuate surface, changes its direction at the side wall, and is again involved in the ascending current from the burner and circulates.

  Since many through holes are scattered except for the vicinity of the top of the dome-shaped top, the flames and hot air that hit the center top generate a downward flow along the arcuate surface. A part of the flame and hot air is discharged, but in order to constrain the discharge by the tongue protruding to the front or back side of the through hole, it is sufficiently lowered to the peripheral edge and heated to heat it red. The heat plate has the effect of making the entire heat plate a uniform heat source.

  Furthermore, the tongue protruding to the front or back side controls flame and hot air, and at the same time, it has the effect of being heated to the tip of the tongue in contact with the flame and hot air and becoming red-hot. The hole exhibits an effect of facilitating smooth discharge and promoting a smooth circulation flow.

  In the invention of claim 2, in addition to the effect of the invention of claim 1, the through-hole having a tongue piece projecting on the front surface side has a tongue piece projecting on the back surface side on the inner side near the central top portion. Since the through-holes are arranged, not only the top on the hot plate, but also the gravy dropped on the through-hole arranged on the inner side near the center top flows along the tongue piece toward the lower end of the outer periphery, and the outer back side It falls into the lower water tank from the through hole having the tongue piece protruding to the bottom, has the effect of preventing falling into the burner and its vicinity and preventing it from becoming dirty, and dropping and storing gravy etc. in the water tank Is.

  Moreover, since only the through-holes are drilled around the outermost part near the end part, the exhaust gas staying in the hot plate can be discharged smoothly, and the tongue protruding on the back side of the central part or the outer side can be obtained. The through hole having a piece has an effect of easily cleaning dirt on the surface because no obstacles protrude on the surface.

  In the invention of claim 3, since the base portion of the tongue piece is connected to the end face on the central top portion side of the through hole, and the tip portion protrudes to the outside in the direction of the peripheral end portion, the effects of claims 1 and 2 are further improved. It can be achieved reliably.

  In the invention of claim 4, in addition to the effect of any one of claims 1 to 3, the angle between the protruding tongue piece and the through hole surface is increased as the through hole is located on the outer side in the peripheral end direction. In addition, the effect of being able to uniformly heat the entire hot plate by restricting the discharge of the flame and hot air from the upper hole and extending it to the peripheral end is achieved.

  The invention of claim 5 has the effect of easily and reliably forming the through hole and the tongue piece in addition to the effect of any one of claims 1 to 4.

It is a top view of the hot plate of the present invention. It is an end view of the AA line of FIG. It is sectional drawing which shows a use condition.

Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a view showing an embodiment of the present invention, FIG. 1 is a plan view of a hot plate of the present invention, FIG. 2 is an end view taken along line AA, and FIG. 3 is a sectional view showing a use state.

The hot plate 1 is a steel material having a circular plane, the center portion swells in a dome shape, and a side wall 2 is suspended from the peripheral end portion, and a large number of through holes are scattered except in the vicinity of the dome-shaped central top portion. It is set up.
In the through-hole, a base 41 is connected to a part of the end face of the through-holes 3A and 3B, and a tongue piece is projected to the front side 11 or the back side 12 so as to cover the through-holes 3A and 3B. 4A and 4B are provided.

  A through-hole 3A having a tongue piece 4A projecting on the front side 11 is arranged on the inner side near the central top, and a through-hole 3B having a tongue piece 4B projecting on the back side 12 is arranged on the outer side, and further on the outermost side. Only the through hole 3C is formed in the periphery near the end.

The base portions 41 of the tongue pieces 4A and 4B are connected to the end surfaces of the through holes 3A and 3B on the central top portion side, and the tip portion 42 protrudes outward in the peripheral end direction.
In addition, the angle between the protruding tongue pieces 4A and 4B and the surfaces of the through holes 3A and 3B increases as the through holes 3A and 3B are positioned on the outer side in the peripheral end direction.

  The shapes of the through holes 3A and 3B and the tongue pieces 4A and 4B are not limited to the shape of the drawing, and can be arbitrarily designed. The through hole 3C having no tongue piece is also limited to the oval shape of the drawing. It is not a thing.

For example, the through holes 3A and 3B and the tongue pieces 4A and 4B are provided with a single continuous cut 31 in the hot plate 1 and a straight line connecting the ends thereof as a fold line 32 to the front side 11 or the back side 12 The through-holes 3A and 3B can be formed by bending the tongues 4A and 4B, and the bent portions 4A and 4B can be formed.
By doing so, the through holes 3A and 3B and the tongue pieces 4A and 4B can be easily formed in the same shape, and the bending angle can be determined reliably.

Next, the usage method of this hot platen 1 is demonstrated based on FIG.
A gas unit case 6 is installed at the bottom of the main body case 5 of the roaster, a burner 61 is erected at the center, and a water tank 7 formed in the main body case 5 outside the burner 61 is installed on the main body case 5. .

The hot plate receiving frame body 8 is supported on the inner wall 71 standing so as to surround the burner 61 in the water tank 7, the hot plate 1 is placed on the hot plate receiving frame body 8, and the flame generated by the burner 61 is increased. The hot plate 1 is disposed on the surface.
Further, the grill 9 is placed on the receiving seat 73 of the outer wall 72 of the water tank 7 above the arranged hot plate 1 to prepare for cooking such as meat.

  Therefore, when the burner 61 is ignited, the flame and hot air emitted from each jet outlet of the burner 61 hit the center top of the back surface of the hot plate 1 and descend to the periphery along the dome-shaped surface, and a large number of through holes 3A, 3B, The meat placed on the grill 9 located above and dispersed and sprayed to 3C is heated evenly.

At the same time, the hot plate 1 itself is heated and reddened, and the tongues 4A and 4B protruding to the front side 11 or the back side 12 are also heated and reddened simultaneously with the restriction of flames and hot air. Even the meat is heated.
Therefore, the meat is baked as well as charcoal fire.

Further, since the hot plate 1 has a dome shape and the side wall 2 is vertically provided at the peripheral end, the flame of the burner 61 does not escape from the peripheral edge of the hot plate 1 and the heat efficiency is good.
The angle between the protruding tongue pieces 4A and 4B and the through-hole surface is larger as the through-holes 3A and 3B are located on the outer side in the peripheral end direction, and the discharge from the through-hole of flame and hot air is restricted to the upper part. The entire heating plate can be heated evenly so that it reaches the peripheral edge.

  Furthermore, the gravy dropped on the top hole on the hot plate 1 or the through hole 3A arranged on the inner side close to the center top flows along the tongue piece 4A toward the outer peripheral lower end and protrudes to the outer back surface 12 side. It falls from the through-hole 3B having the tongue piece 4B or the through-hole 3C to the lower water tank 7 and prevents the gravy from dropping and fouling the burner 61 and its vicinity.

Since only the through-holes 3C are formed in the outermost periphery and close to the end portion, the exhaust gas staying in the hot plate 1 can be discharged smoothly.
And since the obstructing thing does not protrude in the surface side 11 in the through-hole 3B and the through-hole 3C which have the tongue piece 4B which protruded in the center part of the hot platen 1 or the outer back side 12, the surface dirt is easy. It can be cleaned.
