However, when the two lower heat burners are arranged, not only the parts such as the piping and the ignition electrode are required twice, but also the assembly process is increased, resulting in high cost. In addition, if two lower heat burners are provided in the grill, not only the size of the food to be cooked in the grill is limited, but also many parts protrude into the grill. , Inferior in cleanability. In particular, if the width of the grill is narrowed in order to cope with the recent miniaturization of the cooker, the space for accommodating the food to be cooked in the grill is further reduced by the left and right lower heat burners.

The present invention has been made in view of the above problems, and an object of the present invention is to reduce the size of a cooker suitable for miniaturization, which is excellent in cleanability, while ensuring a space for accommodating an object to be cooked in the grill. It is to provide at cost.

According to the present invention
A grill storage that houses the grill plate on which the food to be cooked is placed,
It is equipped with a lower fire burner arranged along one of the left and right side walls of the grill.
The grill plate is located on the inner surface of one side wall on the left and right side walls of the grill where the lower heat burner is arranged, and on one side of the one side wall where the lower heat burner is arranged on the left and right ends of the grill plate. Housed in the grill so that the first lateral gap between the ends is narrower than the second lateral gap between the inner surface of the other side wall of the grill and the other side edge of the grill plate. A cooker that has been cooked is provided.

According to the above-mentioned cooking cooker, since one lower heat burner is arranged along one of the left and right side walls of the grill, the number of parts can be reduced and the assembly process can be reduced. In addition, the number of parts protruding into the grill can be reduced, and the cleanability can be improved. Further, even if the size of the grill storage is reduced, it is possible to secure a space for accommodating the food to be cooked in the grill storage.

On the other hand, when the object to be cooked is placed on a gridiron with a large gap made of wire and cooked by heating, if the lower heat burner is arranged only on one side wall side, the combustion ejected from the lower heat burner The exhaust flows short-circuited from the lower side to the upper side of the side wall on which the lower fire burner is arranged. Therefore, one side wall side on which the lower heat burner is arranged is heated to a higher temperature than the other side wall side, and uneven baking is likely to occur.

However, according to the above-mentioned cooking utensil, since a grill plate having better heat transfer property than a gridiron is used as a cooking utensil, the heat on one side wall side heated by the combustion exhaust ejected from the lower heat burner is transferred to the grill plate. The heat can be transferred to the whole. Then, according to the above-mentioned cooking cooker, the grill plate has a first lateral gap between the inner surface of one side wall on which the lower heat burner is arranged and one side end portion of the grill plate. Since it is housed in the grill so as to be narrower than the second lateral gap between the inner surface of the side wall and the other side end of the grill plate, the ventilation resistance of the combustion exhaust passing through the first lateral gap Is higher than that of the combustion exhaust passing through the second lateral gap, and a short circuit of the combustion exhaust upward from the first lateral gap can be suppressed. As a result, the combustion exhaust easily flows in the space below the grill plate from one side wall side to the other side wall side, so that the lower surface of the grill plate can be heated uniformly on the left and right sides. Therefore, even when one lower heat burner is provided, uneven baking of the object to be cooked can be reduced.

According to the above-mentioned cooker, when the grill plate is housed in the grill, the ventilation resistance of the combustion exhaust ejected from the lower heat burner to the rear of the grill is provided between the grill plate and the bottom wall of the grill. Since the resistance means is provided so as to be higher on the rear side than on the front side, the front surface of the lower surface of the grill plate having low ventilation resistance is easily heated by the combustion exhaust ejected from the lower fire burner on one side wall side. As a result, the lower surface of the grill plate can be heated uniformly in the front-rear and left-right directions, and even when one lower heat burner is arranged, uneven baking of the object to be cooked can be reduced.

Preferably, in the above cooking device,
The resistance means consists of an upwardly convex ridge extending in the left-right direction provided on the bottom wall of the grill.
The ridge is provided so as to be inclined so that one end on one side wall on which the lower fire burner is arranged is located in front of the grille from the other end on the other side wall.

According to the above-mentioned cooking cooker, the bottom wall of the grill is provided with a resistance means consisting of upwardly convex ridges extending in the left-right direction, and the ridges have one end on one side wall side and the other side wall. Since it is inclined so as to be located in front of the grill storage from the other end on the side, the combustion exhaust gas ejected from the lower fire burner on one side wall side is the lower surface of the grill plate having low ventilation resistance due to the ridges. While heating the front of the grill, it becomes easier to flow toward the second lateral gap. As a result, the lower surface of the grill plate can be heated uniformly in the front-rear and left-right directions, and even when one lower heat burner is arranged, uneven baking of the object to be cooked can be reduced.

As described above, according to the present invention, it is possible to provide a cooking cooker having excellent cleanability and suitable for miniaturization at low cost while securing a space for accommodating an object to be cooked in the grill.

As shown in FIGS. 2 and 3, the upper wall 24 of the grill 20 is provided with a top heat burner 56 for heating the food to be cooked from above. The upper fire burner 56 is, for example, a surface combustion type ceramic burner whose lower surface is made of a ceramic plate, and a flame hole 560 is provided on the lower surface of the plate. Therefore, when the fuel gas and the primary air are supplied from the mixing pipe (not shown) and the top heat burner 56 is ignited, a combustion flame of the fuel gas is formed on the lower surface of the plate body, and its radiant heat and combustion exhaust are formed. Is radiated downward in the grill 20. Although not shown, the flame hole 560 of the top burner 56 faces an electrode portion of an ignition electrode for igniting a fuel gas and a thermocouple for detecting a combustion flame.

In the lower region of the right side wall 22 of the grill chamber 20, a long introduction port 202 is opened in the front-rear direction. The introduction port 202 is in front of the right side wall 22 of the grill storage 20 so that the center in the front-rear direction is located in front of the center in the front-rear direction of the grill plate 80 when the grill plate 80 is housed in the grill storage 20. It is formed closer. Further, the introduction port 202 is formed so that the upper end is located below the upper end of the right end portion 84 of the grill plate.

On the outside of the right side wall 22 of the grill chamber 20, one lower fire burner 55 extending in the front-rear direction along the right side wall 22 is arranged, and a plurality of flame holes 550 face the introduction port 202. The lower fire burner 55 has, for example, a plurality of openings forming a slit-shaped flame hole 550 by punching a predetermined portion, and a single metal plate formed is bent in the vicinity of the openings and is substantially straight tubular. It is formed by molding and joining the ends of a metal plate. The lower fire burner 55 includes a burner body 500 formed in an elongated flat plate shape, an inflow portion 551 into which a gas nozzle (not shown) is inserted, and a horizontally extending flange portion 552 to which a metal plate is joined to the outer side in the left-right direction. Have.

The plurality of flame holes 550 are opened in the left-right direction and inward of the grill storage 20 at predetermined intervals in the front-rear direction along the left-right inner edge portion of the lower fire burner 55, and are sucked by the inflow portion 551. The fuel gas supplied to the lower heat burner 55 together with the primary air is ejected inward in the left-right direction of the grill 20. Therefore, when the lower heat burner 55 is ignited, a combustion flame is formed in the flame hole 550, and the combustion exhaust thereof is central to the left and right through the introduction port 202 opened in the front side of the right wall 22 of the grill storage 20. It is ejected toward. Although not shown, the flame hole 550 of the lower burner 55 faces an electrode portion of an ignition electrode for igniting a fuel gas and a thermocouple for detecting a combustion flame.

An exhaust overflow prevention cover 600 having a substantially L-shaped cross section is connected to the outer surface of the right side wall 22 of the grill storage 20 so as to cover the lower fire burner 55 from above and from the left and right outside, and the upper edge of the opening of the introduction port 202. A straightening vane 601 extending diagonally upward and outward toward the upper side of the lower fire burner 55 is connected to the lower heat burner 55. A certain size of gap is formed between the lower end of the exhaust overflow prevention cover 600 and the upper surface of the lower fire burner 55, and between the inner surface of the exhaust overflow prevention cover 600 and the outer end of the straightening vane 601. ing. Therefore, when the lower heat burner 55 is ignited, the secondary air flowing in from the gap between the exhaust overflow prevention cover 600 and the lower heat burner 55 is supplied from above the lower heat burner 55 to the vicinity of the flame hole 550 by the rectifying plate 601. Then, the combustion exhaust is blown to a distant place in the grill chamber 20 by the secondary air. As a result, the left and right central portions on the lower surface of the grill plate 80 can be efficiently heated.

An exhaust opening 11 communicating with the exhaust passage 300 is provided in the upper rear portion of the grill chamber 20. The rear wall 25 of the grill storage 20 includes a lower rear wall 25a that stands vertically from the bottom wall 23 to a predetermined height, and an upper rear wall 25b that extends diagonally upward and rearward from the upper end of the lower rear wall 25a. Have. An exhaust duct 30 is continuously provided at the upper end of the upper rear wall 25b, and the exhaust duct 30 constitutes an exhaust passage 300. An internal temperature sensor 70 for detecting the internal temperature is disposed in the left and right central portions in the vicinity of the lower side of the upper rear wall 25b of the grill chamber 20.

A raised portion 23a having an inclined surface that rises rearward is formed in the rear left and right central portion of the bottom wall 23 of the grill storage 20, and an instrument temperature sensor 71 is housed in the top surface portion of the raised portion 23a. The sensor cover 72 is arranged so as to project upward. Further, small raised portions 23b having a protruding height lower than that of the raised portions 23a are formed on both rear left and right ends of the bottom wall 23 of the grill storage 20.

Although not shown, the left and right central portions of the rear frame portion of the support frame 220 that supports the grill plate 80 from below are bent upward. Therefore, when the grill door 5 is closed with the grill plate 80 mounted on the support frame 220, the left and right ends of the rear frame portion of the support frame 220 ride on the small raised portions 23b, and the grill plate is accompanied by this. The rear part of the 80 is lifted upwards. As a result, the grill plate 80 is moved rearward without colliding with the sensor cover of the appliance temperature sensor 71. Then, when the grill door 5 is further closed and the left and right ends of the rear frame portion of the support frame 220 get over the small raised portions 23b, the support frame 220 becomes a substantially horizontal state, and the grill plate 80 in a substantially horizontal state accordingly. The lower surface of the sensor cover 72 comes into contact with the upper surface of the sensor cover 72 from above.

As shown in FIGS. 2 to 4, when the grill plate 80 is housed in the grill 20, the grill plate 80 is arranged closer to the right rear side in the grill 20. The size and shape are set in. Specifically, when the grill plate 80 is housed in the grill storage 20, the grill plate 80 closest to the inner surface of the right side wall 22 of the grill storage 20 and the inner surface of the right side wall 22 in the left-right direction of the grill storage 20. A first lateral gap G1 (for example, 2 mm) having a predetermined size is formed between the right end portion 84 of the grill, and is closest to the inner surface of the left side wall 21 of the grill storage 20 and the inner surface of the left side wall 21. A second lateral gap G2 (for example, 20 mm) having a predetermined size is formed between the grill plate 80 and the left end portion 83. Further, when the grill plate 80 is housed in the grill storage 20, the inner surface of the upper rear wall 25b of the grill storage 20 and the grill plate 80 closest to the inner surface of the upper rear wall 25b in the front-rear direction of the grill storage 20 A rear gap Gb (for example, 2 mm) having a predetermined size is formed between the rear end portion 87 and the rear end portion 87. Therefore, when the grill plate 80 is housed in the grill box 20, the grill plate 80 is housed in the grill box 20 so that the first lateral gap G1 and the rear gap Gb are narrower than the second side gap G2. Has been done. Preferably, the grill plate 80 is housed in the grill chamber 20 so that the first lateral gap G1 and the rear gap Gb are as narrow as possible.

According to the present embodiment, since the lower fire burner 55 is arranged only on the right side wall side of the grill storage 20, a pair of left and right lower fire burners 55 are arranged inside the left and right side walls 21 and 22 of the grill storage 20. Compared with the conventional cooker installed, parts such as piping, ignition electrode, thermocouple, and rectifying plate can be reduced, and the assembly process can be reduced. As a result, the cost can be reduced.

Further, according to the present embodiment, the lower fire burner 55 is arranged on the outside of the right side wall 22 of the grill storage 20, and there are few parts protruding into the grill storage 20, so that the grill storage 20 can be easily cleaned. It becomes.

Further, according to the present embodiment, since the lower fire burner 55 is arranged only on the right side wall side of the grill storage 20 and is arranged outside the right side wall 22 of the grill storage 20, the grill storage 20 is arranged. It is not necessary to secure a space for arranging the lower heat burner 55 in the grill 20, and substantially all the space in the grill 20 can be used as a space for accommodating the food to be cooked. As a result, even if the width of the grill storage 20 is narrowed, the space for accommodating the food to be cooked in the grill storage 20 can be secured to the same level as in the conventional case. Therefore, it is possible to provide a cooking device suitable for miniaturization.

On the other hand, when the lower fire burner 55 is arranged only on the right side wall side of the grill storage 20 as described above, the left and right side walls 21 and 22 in the grill storage 20 and the left and right end portions 83 and 84 of the grill plate 80 When the grill plate 80 is arranged so that the first and second lateral gaps G1 and G2 between the two are even, the combustion ejected from the introduction port 202 of the right side wall 22 toward the inside of the grill chamber 20 The exhaust easily flows upward through the first lateral gap G1 between the right side wall 22 on which the lower combustion burner 55 is arranged and the right end portion 84 of the grill plate 80, and easily flows. It is difficult for the combustion exhaust to flow sufficiently to the side. Therefore, the food to be cooked is heated to a higher temperature on the right side wall side on which the lower heat burner 55 is arranged than on the left side wall side. Further, when the exhaust passage 300 communicating with the outside is provided at the rear, if the grill plate 80 is arranged at the center of the front and rear of the grill 20, the grill plate 80 is provided from the introduction port 202 of the right wall 22 to the inside of the grill 20. The combustion exhaust gas ejected toward the grill is short-circuited to the exhaust passage 300 through the rear gap Gb between the inner surface of the upper rear wall 25b of the grill storage 20 and the rear end portion 87 of the grill plate 80, and easily flows. The rear side of the grill plate 80 is heated to a higher temperature than the front side. As a result, the food to be cooked is heated unevenly, and uneven baking is likely to occur.

However, according to the present embodiment, since the grill plate 80 having better heat transfer property than the grill is used as the cooking utensil, the heat on the right wall side heated by the combustion exhaust gas ejected from the lower heat burner 55 is transferred to the grill plate. The heat can be transferred to the whole of 80. Further, in the grill plate 80, the first lateral gap G1 between the inner surface of the right side wall 22 of the grill storage 20 and the right end portion 84 of the grill plate 80 is the inner surface of the left side wall 21 of the grill storage 20 and the grill plate 80. Since it is housed in the grill 20 so as to be narrower than the second lateral gap G2 between the left end portion 83, the ventilation resistance of the combustion exhaust passing through the first lateral gap G1 is on the second side. It is higher than that of the combustion exhaust passing through the square gap G2, and it is possible to suppress a short circuit of the combustion exhaust upward from the first lateral gap G1. As a result, the combustion exhaust easily flows in the space below the grill plate 80 from the right side wall side to the left side wall side, so that the lower surface of the grill plate 80 can be heated uniformly on the left and right sides. Therefore, even when one lower heat burner 55 is arranged on the right side wall side, the uneven distribution of the temperature in the left-right direction of the grill plate 80 can be reduced, and the uneven baking of the object to be cooked can be reduced.

Further, in the present embodiment, in the grill plate 80, the rear gap Gb between the inner surface of the upper rear wall 25b of the grill storage 20 and the rear end portion 87 of the grill plate 80 is narrower than the second lateral gap G2. Since it is housed in the grill 20 as described above, the ventilation resistance of the combustion exhaust gas ejected from the right wall side into the grill 20 through the rear gap Gb of the combustion exhaust passes through the second side gap G2. It becomes higher than that, and it is possible to suppress a short circuit of the combustion exhaust from one side wall side to the rear gap Gb. As a result, even when the exhaust passage 300 is provided in the rear, the combustion exhaust easily flows from the right side wall side toward the second lateral gap G2 in front of the grill storage 20 having a lower ventilation resistance than the rear gap Gb. , The lower surface of the grill plate 80 can be uniformly heated back and forth. Therefore, even when one lower heat burner 55 is arranged on the right side wall side, the uneven distribution of the temperature in the front-rear direction of the grill plate 80 can be reduced, and the uneven baking of the object to be cooked can be reduced. ..

Further, according to the present embodiment, the introduction port 202 is arranged closer to the front of the right side wall 22, and a plurality of lower flame burners 55 opening to the introduction port 202 inward in the left-right direction of the grill storage 20. The flame hole 550 is facing. Therefore, the center position of the plurality of flame holes 550 in the front-rear direction is located in front of the center position of the grill plate 80 in the front-rear direction. Moreover, since the upper end of the introduction port 202 is located below the upper end of the right end portion 84 of the grill plate 80, the combustion exhaust gas ejected from the lower heat burner 55 is below the grill plate 80 via the introduction port 202. It flows into the space. As a result, the front surface of the lower surface of the grill plate 80 is easily heated by the combustion exhaust gas ejected from the lower heat burner 55, and the lower surface of the grill plate 80 can be uniformly heated in the front, rear, left and right directions.

Further, in the present embodiment, since the raised portion 23a and the small raised portion 23b are formed behind the bottom wall 23, the space below the grill plate 80 is narrower in the rear than in the front, and the combustion exhaust is exhausted. Ventilation resistance increases. That is, these raised portions 23a and 23b function as resistance means for increasing the ventilation resistance of the combustion exhaust gas flowing rearward in the space below the grill plate 80 on the rear side rather than the front side. As a result, the front surface of the lower surface of the grill plate 80 having a low ventilation resistance is easily heated by the combustion exhaust gas ejected from the introduction port 202 into the grill chamber 20. As a result, the lower surface of the grill plate 80 can be heated uniformly in the front-rear and left-right directions.

As described above, according to the present embodiment, even if one lower heat burner 55 is arranged along one side wall, the food to be cooked can be uniformly heated in the front, back, left and right, and the baking unevenness. It is possible to obtain a small amount of food to be cooked. Therefore, according to the present embodiment, it is possible to provide a cooking cooker having excellent cleanability and suitable for miniaturization at low cost while securing a space for accommodating the object to be cooked in the grill cabinet 20.
