Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hot plate type grill that attaches a grill burner to a grill warehouse, heats a hot plate installed upward by the grill burner, and cooks an object to be cooked by the hot plate.
[0002]
[Prior art]
A hot plate grill is a grill burner having a crater having a left flame hole row along the left side wall and a right flame hole row along the right side wall in a grill cabinet having a front surface serving as an entrance / exit of an object to be cooked Is installed, the outer edge of the hot plate mounted on the upper side is heated, and the food to be cooked below is heated by the radiant heat radiated from the hot plate.
[0003]
Providing a flame transfer flame array for the left and right flame hole arrays as the grill burner has the advantage that only one ignition device and burner are required. If this flame transfer flame hole array is formed on the front surface of the grill cabinet, the entrance / exit of the object to be cooked cannot be made large, so that it is not convenient. For this reason, as shown in FIG. 4, a U-shaped burner having a substantially U-shaped crater in which the left and right flame hole rows are connected on the rear side (back side) of the grill cabinet and the front side is missing is used.
[0004]
The hot plate has a central portion in which a long ventilation window is formed in the front-rear direction in order to improve the combustion of the grill burner. In order to improve the heating efficiency of the cooked object, the hot plate is inclined downward from both the left and right sides of the central portion. In general, the structure has left and right inclined parts extended to the surface, and a large number of slits, concavities and convexities, vent holes, etc. are formed on the entire surface of the hot plate to increase radiant heat by improving heat absorption and heat dissipation. ing.
[0005]
[Problems to be solved by the invention]
The front side portion of the grill cabinet is easily lowered in temperature due to the intake of air from the entrance and the heat radiation from the door glass because the entrance of the cooking object is on the front surface of the grill cabinet. Further, when a U-shaped burner is used for the grill burner, the temperature of the front side of the grill box where the flame plate is missing is reduced. As a result, there is a problem that the temperature in the grill is not uniform.
SUMMARY OF THE INVENTION An object of the present invention is to provide a hot plate type grill having a heating source in which a grill burner and a hot plate are combined, and capable of maintaining a high temperature at the front of the grill cabinet and making the temperature distribution in the grill cabinet uniform. is there.
[0006]
[Means for Solving the Problems]
This invention comprises a grill chamber having an entrance for a cooking object on the front surface, a grill burner provided with a crater having a left flame hole row along the left side wall and a right flame hole row along the right wall of the grill cabinet, A hot plate type grill provided with a hot plate having a ventilating window extending in the front-rear direction at the center and provided with fins projecting downward on the left and right edges of the front part of the venting window, Thus, the heat exhaust flowing in the ventilation window along the lower surface of the hot plate is deflected downward. A method of providing fins projecting downward on the left and right edges over substantially the entire length of the ventilation window and setting the width of the front fin larger than the width of the rear fin is practical and inexpensive.
[0007]
[Effects of the invention]
In the present invention, since the hot airflow circulating downward along the fins of the hot plate is increased at the front part in the grill cabinet, the temperature of the front part of the grill cabinet where the temperature tends to be lower than the rear part is increased. Highly maintainable. For this reason, uniform temperature distribution in the grill can be easily and reliably achieved at low cost.
[0008]
It should be noted that the selective increase in the amount of recirculation of the heat exhaust downward at the front part in the grill cabinet is based on the presence / absence of fins at the front part and rear part of the ventilation window (Claim 1) and the width of the fin (Claim 2). In addition to a fin having the same width and the same inclination, a method of providing a vent hole in the rear portion, a method of adjusting the angle of the fin in the front and rear, a method of adjusting the width of the vent window in the front and rear, or a combination of these appropriately May be executed.
[0009]
The invention according to claim 4 is characterized in that the width of the front portion of the hot plate is set larger than the width of the rear portion from the center. Thereby, the radiant heat from the hot plate is selectively increased at the front part of the grill box, so that the temperature of the front part of the grill box can be maintained high, and the temperature distribution in the grill box can be made more uniform.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a hot plate type grill 10 of the present invention. A grill burner 2 is attached to the upper part of the grill cabinet 1, and the hot plate 3 is arranged above the grill burner 2. A soup pan 11 is installed at the bottom of the grill cabinet 1 so that it can be inserted and removed freely. A grill net 12 is placed on the soup pan 11. In the grill 12, a cooking object A is placed on the front part 1A of the grill box 1 shown in FIG. 1, and a cooking object B is placed on the rear part 1B of the grill box 1 shown in FIG.
[0011]
The front surface of the grill cabinet 1 is an entrance for the front and rear cooking objects A and B placed on the soup pan 11 and the grill 12, and can be opened and closed by a door (not shown). The top plate 13 of the grill cabinet 1 also serves as an exhaust cover, and has a structure that bulges upward for smooth exhaustion. A substantially rectangular exhaust port 14 that is long in the front-rear direction is formed at the center to bulge upward. Has been. In this embodiment, the exhaust port 14 is a central exhaust type grille opened in the center of the top plate 13 of the grill cabinet 1, but a rear exhaust type grille provided with an exhaust port behind the grill cabinet 1 is used. There may be.
[0012]
The grill burner 2 includes a left flame hole row 21 and a right flame hole row 22 that are horizontally formed in the front-rear direction along the upper portions of the left and right side walls 15 and 16 of the grill cabinet 1, and the left and right flame hole rows 21, This is a U-shaped burner (see FIG. 4) having a substantially U-shaped crater 20 consisting of a rear-side flame-transfer flame hole array 23 formed horizontally for 22 fire-transfers. The grill burner 2 can ignite all the flame hole rows with one ignition device (not shown), and forms a flame row F (shown in FIGS. 1 and 2) in a substantially U shape by ignition.
[0013]
As shown in FIGS. 3, 5, and 6, the hot plate 3 has a planar shape corresponding to the flame row F and has a three-fold substantially trapezoidal cross-sectional shape corresponding to the shape of the top plate 13. It is formed with. The hot plate 3 is a strip-shaped central portion 31 that is horizontally long and extends in the front-rear (left and right in FIG. 5) direction of the grill cabinet 1, and is extended from both the left and right sides of the central portion 31 and tilted downward by about 15 degrees. Inclined side portions 32 and 33.
[0014]
A large number of slits 34 are formed on the entire surface of the hot plate 3, and a bulging portion 35 is formed along the slit 34. A large number of small holes 36 are appropriately formed in the bulging portion 35. The inclination angle of the left and right inclined side portions 32 and 33, and the size, number, and shape of the slit 34, the bulging portion 35, and the small hole 36 are appropriately set so as to efficiently receive heat from the flame train F and release radiant heat downward. To be determined. A ventilation window 4 having substantially the same shape as the exhaust port 14 is formed in the central portion 31 at the same position, and the heat exhaust of the flame train F flows to the ventilation window 4 along the lower surface of the hot plate 3, and from the exhaust port 14. It is supposed to be discharged.
[0015]
The hot plate 3 is beaten by the flame train F generated at the crater 20 and rises in temperature. However, since the front part 3A is a missing part of the flame train F, the temperature is lower than that of the rear part 3B. Radiant heat is released from the hot plate 3 at a high temperature, and the cooking objects A and B before and after being placed on the grill 12 are heated, but the temperature of the front portion 3A of the hot plate 3 is lower than that of the rear portion 3B. In addition, with only radiant heat, the temperature distribution in the grill 1 is likely to be lower at the front portion 1A (shown in FIG. 1) than at the rear portion 1B (shown in FIG. 2).
[0016]
The ventilation window 4 is formed with fins 5 and 5 that are bent downward at an angle of 85 degrees at the left and right edges. In the fins 5 and 5, the width D1 of the front side portion 51 of the ventilation window 4 (see FIG. 1) is set such that D1> D2 with respect to the width D2 of the rear side portion 52. Due to the fins 5 and 5, the heat exhaust of the flame row F of the grill burner 2 collides with the lower surfaces of the left and right inclined side portions 32 and 33 and flows to the center side (ventilation window 4 side). The portions 32 and 33 are heated upward through the small hole 36 and the slit 34, flow along the lower surface of the top plate 13, and are exhausted from the exhaust port 14.
[0017]
As shown in FIG. 1, in the front part 1 </ b> A of the grill cabinet 1, another part of the heat exhaust flow of the flame train F is deflected downward by the front side parts 51, 51 of the fins 5, 5 to become a descending hot air flow C. The object A to be cooked on the grill 12 is heated, and the remainder flows upward from the ventilation window 4. At this time, since the width D1 of the front side portion 51 of the fin 5 is large in the front portion 1A, most of the front portion 1A becomes the descending hot air flow C and heats the cooking object A on the grill net 12.
[0018]
On the other hand, in the front part 1B of the grill box 1, as shown in FIG. 2, the rear side part 52 of the fin 5 has a small width D2, so that most of the heat exhaust flow flows upward from the ventilation window 4. As a result, the cooking object A placed on the front of the grill 12 is heated by the descending hot air flow C, so that the temperature inside the grill cabinet 1 can be made uniform as a whole, and uniform cooking is possible. Become.
[0019]
In this embodiment, the full width W of the heat plate 3 is provided with widened portions 37 and 38 that extend the front side portions of the left and right inclined side portions 32 and 33 outward by a width E as compared to the rear side portion, and the front side portion is the rear side. It is formed 2E wider than the part. This has the effect of increasing the heat radiation area of the front portion 3A of the hot plate 3 and increasing the temperature of the front portion 1A of the grill 1.
[0020]
In addition to the method of increasing or decreasing the width D of the fins 5 at the front and reducing or eliminating the width of the fins 5 at the front 1A of the grill cabinet 1, the width of the ventilation window 4 is reduced at the front. Naturally, the inclination angle of the fin 5 may be adjusted, a vent hole may be formed in the fin 5, or a combination thereof may be performed. In addition, the cross-sectional shape of the hot plate 3 may be an inverted V shape, an arc shape, a polygonal shape, or the like other than the trapezoid of the above embodiment, but it is desirable that the central portion bulges upward.
