In this type of conventional pottery cooker, only one of the upper and lower surfaces is heated, and after the object to be cooked is inverted, the other side is baked. The object placed on the object supporting means at a specific position, such as the vicinity of the object, has a disadvantage that the object to be cooked is less likely to be burned than the object placed in the middle or the like, and grilling unevenness easily occurs.

If gas burners are installed above and below the object supporting means, the upper and lower surfaces of the object can be fired at the same time, so that the time for cooking the object can be reduced. However, a specific portion such as the vicinity of the doorway has a large heat dissipation or an invasion of the outside air, so that there is a problem that unevenness in burning occurs. Further, if the rows of flame holes of the upper and lower gas burners are in the same direction and at a wide interval, heating from the flames generated in the upper and lower rows of flame holes becomes non-uniform, so that it is easy to cause unevenness in burning.

[0005] It is an object of the present invention to provide a pottery cooker capable of minimizing the occurrence of uneven grilling along the entire surface of the object supporting means. A third object of the present invention is to provide a pottery cooker capable of minimizing the occurrence of uneven grilling on the upper surface of the object placed on the front of the object supporting means. .

The lower burner 3 has eight pipe-type burners 31 arranged at equal intervals in the front-rear direction. Each pipe-type burner 31 is mounted horizontally, and a large number of flame holes are arranged at the upper end to form eight lower flame hole rows 30. Above each pipe-type burner 31, a hot plate 33 having an arc-shaped cross section for preventing the broth from being applied to the pipe-type burner 31.
(See FIGS. 1 and 3) are attached in parallel. The lower burner 3 is a pressurized burner to which combustion air is forcibly supplied by a blower.
All primary combustion is performed at an air-fuel ratio of 5.

As shown in FIG. 1, the upper burners 4 each have a combustion surface which is inclined about 5 degrees to the back side and is directed downward, and as shown in FIG. It consists of combustion plate type burners 4A, 4A, 4B, 4B, 4C, and 4C arranged in a pair on the left and right in three rows. The combustion plate type burners 4A, 4A located at the foremost part are the rod body 2 on the front side.
It is installed almost directly above 1. The combustion plate type burners 4C, 4C located at the innermost part are located forward of the rod 21 on the rear side. The combustion plate type burners 4A, 4A, 4B, 4B,
4C and 4C form three upper flame hole rows 40.
In the upper burner 4 and the lower burner 3, only the right half or the left half can be selected and used.

The elevating mechanism 6 includes the operating lever 61 pivotally supported by a right side wall of the casing 1 and supported by a support shaft 60, and left and right guide rails 6 extending vertically within the casing 1.
2, 62 (see FIGS. 2, 3, and 4), and left and right elevating strips 63, 63 which are guided by the guide rails 62, and reciprocate up and down. The operation lever 61 is provided with a left and right elevating strip 6 in an elongated hole 64 provided at the tip (rear end).
A rod 65 provided to connect the lower ends of 3, 63 is loosely fitted and linked. As described above, the main parts of the lifting mechanism 6 other than the support base plate 66 include the left and right inner walls 1A, 1A,
A is disposed between A and the left and right side walls of the casing 1. The guide rails 62 may be attached to the inner wall 1A.

Slits 1C and 1C are formed in the left and right inner walls 1A and 1A in the vertical direction, and left and right support base plates 66 and 66 are provided horizontally inside the left and right inner walls 1A and 1A. The left and right support base plates 66, 66 are connected to the connecting shaft 6 at the intermediate portion through the slits 1C, 1C.
7 and 67 are connected to the upper ends of the left and right elevating strips 63 and 63, respectively. The left and right ends of the front and rear rod bodies 21 are hung on the front and rear ends of the left and right support base plates 66, 66, respectively.
21 forms a rectangular frame. In other words, the support base plates 66 are components of the elevating mechanism 6 and also components of the cooking object support means 2.

As the upper burner 4, a combustion plate type burner 4A,
4B and 4C are used because they are suitable for heating the object to be cooked below by radiant heat. Also, the lower flame hole row 30
Is 8 rows, whereas the upper row of burner rows 40 is 3 rows because the combustion plate type burners 4A, 4B, 4C are wider than the pipe type burners 31 due to the structure of the combustion plate. Due to structural constraints. Further, a combustion plate type burner 4A,
The reason why the combustion surfaces of 4B and 4C are inclined to the back side by about 5 degrees is that radiant heat generated from the combustion surface leaks out of the entrance / exit 11 of the article to be cooked without a door, and the heating efficiency is reduced. This is to prevent it. The heating efficiency can be considerably improved by inclining the combustion surface of the combustion plate type burner 4A located at the forefront only about 5 degrees to the back side.

The distance between the front combustion plate type burner 4A and the intermediate combustion plate type burner 4B is 120 mm, which is set slightly smaller than the distance between the intermediate combustion plate type burner 4B and the rear combustion plate type burner 4C, 135 mm. I have. This allows
The upper flame hole row 40 is arranged densely on the front side from the back side, and is guided by the rising airflow in the casing 1 so that air is sucked in from the cooking object entrance 11 without a door, and the temperature near the entrance 11 is reduced. The tendency of lowering is suppressed. As a result, it is possible to solve the problem that, among the foods placed on the food support means 2, the cooking of the food near the entrance 11 is less than that of the food placed at the back.

In this pottery cooker, a large number of objects such as fish are placed on the upper surface of the object supporting means 2 and the lower burner 3
Then, the upper burner 4 is ignited, and the pottery is cooked. At this time, the lower flame hole row 30 of the lower burner 3 and the upper burner 4
Are arranged so as to intersect with each other, so that the objects to be cooked are uniformly and simultaneously heated from above and below and are evenly baked. On the other hand, the lower flame hole row 30 and the upper flame hole row 4
When 0 and 0 are arranged in the same direction, uneven grilling is likely to occur,
If the interval between the flame holes is large, the degree of unevenness in burning increases. In the cooking of the grilled product, the level of the cooking object support means 2 is appropriately adjusted by operating the operation lever 61 of the elevating mechanism 6 according to the size of the cooking object.

At the time of cooking the pottery, an upward airflow is generated in the casing 1, and the exhaust gas and the smoke accompanying the cooking of the pottery are discharged from the exhaust port 13. At this time, since air is sucked from the inlet / outlet 11 by being guided by the upward airflow, the inlet / outlet 1
The temperature near 1 tends to be low. For this reason, the cooking object placed on the cooking object support means 2 near the entrance 11 is
The degree of burning is likely to be insufficient. In this case, if the upper flame hole row 40 of the upper burner 4 is set in the left-right direction, the combustion plate type burner 4A located at the forefront can be installed almost directly above the front end of the support 2 for cooking objects. Since the thermal power of the portion can be strengthened, it is possible to prevent a temperature drop near the entrance 11.

Further, by setting the distance between the front side combustion plate type burner 4A and the intermediate combustion plate type burner 4B to be small, it is possible to prevent the temperature near the inlet / outlet 11 from dropping. Further, as described above, by arranging the front-side combustion plate type burner 4A at an angle of about 5 degrees toward the back side, the entrance 1
A decrease in the temperature near 1 can be prevented, and the overall heating efficiency can be improved.

As another embodiment of the present invention, a pottery cooker having only an upper burner without the lower burner in the above embodiment (in this case, the upper burner 4, the object-to-be-cooked support means 2, and the left and right inner walls 1A, 1A), it is possible to achieve the effect of preventing uneven grilling of the object to be cooked. That is, three or more upper burners 4 are arranged side by side in the left-right direction (the direction of the opening 11), and the density of the upper flame hole array 40 is arranged denser on the front side than on the back side. As a result, it is possible to prevent the temperature of the inlet / outlet 11 from lowering and to reduce uneven grilling.

Further, in the case where the upper burners 4 are arranged side by side in the left-right direction (opening direction of the entrance), at least the front upper row of upper burner holes is inclined to the back side to prevent uneven burning. The effect can be improved and the thermal efficiency can be improved. In addition, it is more effective to arrange the density of the upper flame hole array 40 on the front side more densely than on the back side, and to provide the front flame line array 40 on the front row inclined at the rear side.
