  However, in the above-mentioned conventional grille, since the ignition electrode (3) is protruded in a state of being exposed inward from one side surface of the grill case (22), the grill case (22) from the front opening (23) There is a possibility that the to-be-cooked thing (4) and cooking container which are accommodated in an inside may contact an ignition electrode (3). In particular, when the portion to be discharged is also disposed opposite to the electrode portion (3a), a large projecting portion is formed in the upper region in the grill storage (22). As a result, there is a problem that the height of the to-be-cooked material (4) and the cooking container which can be accommodated in the grill storage (22) is limited, and the to-be-cooked material (4) and the cooking container thick in the height direction When placed on a grill or plate and housed in the grill storage (22), there is a problem that the food to be cooked (4) collides with the electrode portion (3a) to damage the electrode portion (3a). Furthermore, when a part of the food to be cooked (4), aluminum foil or the like is caught on the electrode portion (3a) of the ignition electrode (3) and remains there, there is a risk of causing discharge abnormality and causing ignition failure.

  The present invention is taken to solve the problems of the prior art as described above, and the height in the grill storage effective for containing the food to be cooked and the cooking container can be provided as high as possible. It is an object of the present invention to provide a grille which can be stored in the grill storage so as not to contact the food to be cooked and the cooking vessel with the ignition electrode, and which is easy to use and has few ignition failures.

According to the present invention, there is provided an upper burner installed on a ceiling of a grill storage having a front opening which is an inlet / outlet of food and having a large number of flame holes formed on the lower surface, and an ignition electrode for igniting the upper burner. A grill to be provided,
The ignition electrode is a grill provided above the lowermost surface of the ceiling.

  According to the grille, since the ignition electrode is disposed above the lowermost surface of the ceiling, the food or cooking container (hereinafter referred to In the case of collectively representing “cooking matter etc.”), the cooking matter etc. can be accommodated in the grill storage without impeding the accommodation of the cooking matter etc. by the ignition electrode. In other words, when the food or the like is accommodated in the grill storage, the ignition electrode can be accommodated without contacting the food or the like.

Preferably, in the grille,
The height of the lowermost surface of the ceiling portion is set to substantially coincide with the height of the upper side of the front opening.

  The height of the food to be stored in the grill storage needs to be lower than the upper side of the front opening. Therefore, if the height of the lowermost surface of the ceiling portion is made substantially equal to the height of the upper side of the front opening, the height of the food to be accommodated which can be accommodated in the grill storage can be made as high as possible. In addition, since the height of the food is lower than the upper side of the front opening, it is possible to reliably prevent the problem that the food or the like comes in contact with the ignition electrode located above the lowermost surface.

Preferably, in the grille,
The upper burner has a lower open recess in which a portion of the lower surface of the upper burner is recessed upward,
A number of flame holes are formed on the bottom of the recess,
The electrode portion of the ignition electrode is provided to face the recess.

  According to the grille, since the electrode portion of the ignition electrode faces the lower open recess in which a portion of the lower surface of the upper burner is recessed upward, the ignition electrode should be disposed upward by the depth of the recess Can. As a result, it is possible to reliably prevent the inconvenience that the food or the like comes into contact with the ignition electrode. And since a combustion flame is formed also in the crevice which the electrode part of an ignition electrode faces, a to-be-cooked item etc. can be heated uniformly.

Preferably, in the grille,
The upper burner has an upper plate member made of sheet metal and a lower plate member made of sheet metal,
The lower plate member is formed with a lower throttling portion in which a predetermined range is squeezed downward and a downward open recess in which the predetermined range is squeezed upward and recessed upward.
A large number of flame holes are formed in the lower throttling portion and the bottom surface of the recess,
The electrode portion of the ignition electrode is provided to face the recess, and direct spark discharge is made near the flame hole provided on the bottom of the recess.

  According to the above grille, the lower plate member constituting the lower half of the upper burner made of sheet metal has the lower throttling portion squeezing the predetermined range downward and the predetermined range squeezed upward and recessed upward A lower open recess is formed, and a plurality of flame holes are formed on the lower throttling portion and the bottom surface of the recess to form a flame hole forming surface, and the electrode portion of the ignition electrode is formed with a flame hole It is provided to face the recess. As a result, direct spark discharge is generated from the electrode portion in the vicinity of the flame hole of the concave portion provided on the lower surface of the upper burner made of sheet metal, so that the discharge is spouted from the flame hole without providing the portion to be discharged facing the electrode portion. Fuel gas can be ignited. Further, since the electrode portion of the ignition electrode faces the recess located above the lower throttle portion, the ignition electrode can be disposed further upward. This makes it possible to more reliably prevent the inconvenience that the food or the like comes in contact with the ignition electrode.

  As described above, according to the present invention, since the ignition electrode is positioned above the lowermost surface of the ceiling of the grill storage, the effective height in the grill storage for storing the food etc. is increased. While being able to prevent the contact of the to-be-cooked material etc. to an ignition electrode, it can prevent adhesion of a part of to-be-cooked material to an electrode part, and damage to an electrode part. In addition, there is no need to adjust the storage posture or position when storing the food or the like in the grill storage. Therefore, according to the present invention, it is possible to provide a grill which is easy to use and has a low ignition failure.

  The upper burner (1) is installed on the ceiling (11) of the rear exhaust type grill storage (100). The upper burner (1) is configured by combining an upper plate member (1a) formed by pressing a metal plate and a lower plate member (1b), as in a conventional grille burner made of sheet metal. Both the upper plate member (1a) and the lower plate member (1b) are formed in a shape in which the upper and lower halves of the Venturi mixing tube (15) extend laterally from one corner of the substantially rectangular body. . Further, upper and lower outer peripheral flange portions (12a) and (12b) project over the entire outer peripheral region of the upper plate member (1a) and the lower plate member (1b).

  A space in which the fuel gas is supplied from the venturi mixing pipe (15) inward of the upper and lower outer peripheral flanges (12a, 12b) by superposing and connecting these upper and lower outer peripheral flanges (12a, 12b) A part (13) is formed. In the upper burner (1), as shown in FIG. 2, the upper and lower outer peripheral flanges (12a, 12b) are overlaid from above on the peripheral edge of the rectangular opening (110) provided at the center of the ceiling (11) By stopping, it is integrally coupled with the ceiling (11).

As shown in FIG. 1, inside the upper outer peripheral flange portion (12a) of the upper plate member (1a), the upper throttle portion (14a) is formed by squeezing up in a rib shape so as to be upwardly convex. . Further, inside the lower outer peripheral flange portion (12b) of the lower plate member (1b), as shown in FIG. 1 and FIG. 2, three strip-like regions parallel to the long side of the substantially rectangular body and A lower throttling portion (14b) is formed by squeezing down the two band-like regions connecting the front and rear ends of the three band-like regions with each other in a band-like shape so as to be convex downward.
In addition, a recessed portion squeezed upward by a predetermined height so as to divide the lower throttling portion (14b) of the left belt-like region at a predetermined position near the left side wall constituting the grill storage (100) and closer to the rear ) Is formed.
A large number of flame holes (10a) are formed in the bottom of the rear area along the left and right two band areas and the rear side among the three band areas consisting of the lower throttling part (14b) and the bottom face of the recess (33). A substantially U-shaped flame hole forming surface (10) is formed.

  In the grill storage (100), in addition to the above-described upper burner (1), a lower burner (19) extending in the front-rear direction along the left and right lower wall lower regions of the grill storage (100) is disposed. By heating by the upper and lower burners (1) and (19), oil smoke and odor components generated in the grill storage (100) are discharged to the outside from the rear exhaust pipe (16).

  On the back of the grille door, a frame extending toward the rear in the grill storage (100) is connected in a row, and on the frame, a grill pan (40) to receive the cooking fluid and spills of food is placed Be done. Furthermore, a support frame (43) for supporting the grille (41) and the plate (not shown) is provided movably together with the grille door. Thus, when the grille door is opened, the grill pan (40) and the support frame (43) along with the grille (41) or the plate follow the opening operation from the front opening (17) to the outside of the grill storage (100) When it is pulled forward and the grille door is closed, following the closing operation, these are accommodated inside the grill storage (100). A to-be-cooked thing and a cooking container (44) are accommodated in the grill storage (100) from the front opening (17) in the state mounted on the grille (41) or the plate.

  The ceiling portion (11) is, as shown in FIG. 3, formed of an inclined surface which gently descends from the rear to the front. In the present embodiment, the front end of the inclined surface forms the lowermost surface (11a) of the ceiling (11), and the height of the lowermost surface (11a) of the ceiling (11) is the front opening (17). Approximately the height of the upper side (17a).

  When the food or cooking vessel (44) is stored in the grill storage (100), as shown in FIG. 3 or 4, the upper side (17a) of the grille (41) or the front opening (17) from the plate The top surface of the food or cooking vessel (44) is the upper side of the front opening (17) since the food or cooking vessel (44) having a height lower than the maximum height (L1) can be accommodated. It will be located lower than the lowermost surface (11a) of the ceiling part (11) made to substantially correspond to the height of (17a).

  Also, in the left rear upper region in the grill storage (100), an ignition electrode (3) that sparks directly to the vicinity of the flame hole (10a) by applying a predetermined voltage, and the flame hole forming surface (10) And a thermocouple (30) for detecting a combustion state such as ignition or misfire. The ignition electrode (3) and the thermocouple (30) pass through the ceiling (11) and protrude into the grill storage (100).

  As shown in FIGS. 2 and 3, the electrode portion (3a) of the ignition electrode (3) and the tip of the thermocouple (30) are formed on the flame hole forming surface (10 of the lower plate member (1b) of the upper burner (1). ) Facing upward to the recess (33) formed. As described above, a large number of flame holes (10a) are opened on the bottom surface of the recess (33), and a part of the flame hole forming surface (10) is formed. Therefore, the electrode portion (3a) of the ignition electrode (3) and the tip of the thermocouple (30) are disposed to face the large number of flame holes (10a).

Thus, since the electrode portion (3a) of the ignition electrode (3) is projected toward the flame hole (10a) in the recess (33) formed in the lower plate member (1b) made of sheet metal, When an ignition operation is performed by an ignition operation unit (not shown), a discharge path is formed from the electrode portion (3a) toward the vicinity of the flame hole (10a) of the recess (33). As a result, the fuel gas supplied from the venturi mixing pipe (15) into the space (13) of the upper burner (1) and ejected from the flame hole (10a) is ignited and burns over the entire flame hole forming surface (10) A face is formed.
As described above, in the grill storage (100) of the present embodiment, the fuel gas ejected from the flame hole (10a) is ignited by the direct discharge from the ignition electrode (3) to the lower surface of the upper burner (1). There is no need to provide a target portion to be discharged. Therefore, the ignition electrode (3) and the thermocouple (30) can be disposed further upward. In addition, the recess (33) can be easily formed by drawing.

  In addition, the dashed-two dotted line shown in FIG. 3 is a horizontal line (L2) following the lowest surface (11a) of a ceiling part (11), and the ignition electrode (3) and thermocouple (30) which protrude to a grill storage (100) The lower end of is positioned higher than the horizontal line (L2).

The height of the food or cooking container (44) contained in the grill storage (100) is the grille (41) on which the food is placed or the lowermost surface (11a) of the plate to the ceiling (11) Height (L1), that is, lower than the upper side (17a) of the front opening (17). Therefore, for example, together with the grille door, the cooking vessel (44) is placed on the grille (41) pulled out to the front of the grille cabinet (100), and the cooking vessel (44) is stored at the same time as the grille door is closed. The cooking vessel (44) is in the ignition electrode (3) and the thermocouple (30) positioned above the horizontal line (L2) following the lowermost surface (11a) of the ceiling portion (11) even if pushed into the (100) The inconvenience of contact can be prevented. Thereby, if it is a to-be-cooked thing or cooking container (44) which can let front opening part (17) pass, since it can be stored in grill storage (100), in grill storage (100), The effective height which can accommodate a to-be-cooked thing and a cooking container (44) can be made as high as possible.
In particular, the electrode portion (3a) of the ignition electrode (3) faces upward so as to face the inside of the recess (33) formed by squeezing the lower plate member (1b) upward, It is difficult for the cooking vessel (44) to contact the electrode portion (3a) of the ignition electrode (3). As a result, the cooking vessel (44) hits the electrode portion (3a) of the ignition electrode (3) to damage the ignition electrode (3), or part of the object to be cooked or foreign matter such as aluminum foil is the electrode portion (3a Can be reliably prevented.

  Further, the height of the lowermost surface (11a) of the ceiling portion (11) is made to substantially coincide with the upper side (17a) of the front opening (17), and the ignition electrode (3) and the thermocouple (30) are higher In the grill storage (100) as shown in FIG. 4, when the inside of the grill storage (100) is viewed from the front opening (17) of the grill storage (100), as shown in FIG. 3) The thermocouple (30) is in a state of being concealed. Therefore, the user can use a range which has a height (L1) from the grille (41) or plate to the upper side (17a) of the front opening (17) within which the food or cooking vessel (44) can be accommodated. Can be easily understood.

  Therefore, according to the present embodiment, it is possible to provide a grill which is easy to use and has few ignition failures.

  In the above embodiment, the lowermost surface (11a) of the ceiling (11) is provided at the front end of the ceiling (11), but the bottom of the lower squeezing portion (14b) may be the lowermost surface. . In addition, the ignition electrode (3) may be protruded forward from the rear wall of the grill storage (100). In this case, on the lower surface of the rear area along the rear side of the upper burner (1), a recess drawn upward is formed.
