Description

[Technical Field]

[0001] The present invention relates to a grill comprising a grill compartment with an open front, a burner disposed on the side of the grill compartment and extending in the front-to-rear direction, a burner cover extending laterally inward from the side wall of the grill compartment so as to cover the burner from above, and a cover plate removably attached to the inside of the grill compartment so as to cover the upper surface of the burner cover, as well as a stove with a grill equipped with this grill. [Background technology]

[0002] A known example of this type of grill is described in Patent Document 1. In this grill, the cover plate has a mounting plate portion that rests on the burner cover and side plate portions that extend upward from the lateral outer edges of the mounting plate portion to cover the side walls of the grill chamber. A raised portion that protrudes upward is formed at the rear of the burner cover, and a tapered portion that is recessed upward and engages with the raised portion is formed at the rear of the mounting plate portion of the cover plate. Furthermore, a tongue portion that extends forward is provided at the upper front edge of the side plate portion of the cover plate, and a claw portion that engages from below with the lateral inner surface of the tongue portion is provided at the front end of the grill chamber.

[0003] When attaching the cover plate, tilt the cover plate laterally inward on the burner cover using the lateral inner edge of the mounting plate as a fulcrum, and with the bent portion between the mounting plate and the side plate abutting the side wall of the grill chamber, push the cover plate into a position where its rear end abuts the rear wall of the grill chamber, and then raise the cover plate so that the mounting plate is in the correct position to be placed on the burner cover. In this way, without the need for any special alignment, the drawn portions engage with the raised portions and the claws engage with the lateral inner surfaces of the tongues, so that the cover plate is attached without shifting laterally over its entire length in the front-to-rear direction.

[0004] However, in the above-mentioned conventional example, when the cover plate is attached, it is necessary to push the cover plate in the tilted position as described above and then return it to the normal position, which makes the attachment process somewhat troublesome.

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-188851 Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above, the present invention aims to provide a grill and a stove with a grill that are equipped with this grill, which improve the ease of installing the cover plate by allowing the cover plate to be installed simply by pushing it in while keeping it in the correct position. [Means for solving the problem]

[0007] In order to solve the above problems, the first invention of the present application is a grill comprising a grill chamber with an open front, burners arranged on the sides of the grill chamber and extending in the front-rear direction, a burner cover that projects inward in the lateral direction from the side wall of the grill chamber so as to cover the burner from above, and a cover plate that is detachably attached to the inside of the grill chamber so as to cover the upper surface of the burner cover, wherein the cover plate has a mounting plate portion that is placed on the burner cover and a side plate portion that extends upward from the lateral outer edge of the mounting plate portion so as to cover the side wall of the grill chamber, and a first protruding portion that protrudes upward is formed at the rear of the burner cover, and a first narrowing portion recessed upward so as to engage with the first raised portion is formed at the rear of the grill chamber; a guide frame is provided in the grill chamber which engages with the lateral inner surface of the upper edge of the side plate portion of the cover plate and guides the upper edge portion of the side plate portion so as to be movable freely in the front-to-rear direction; a second raised portion protruding upward is formed in a portion of the burner cover located forward of the first raised portion, positioned within the forward projection plane of the first raised portion; a second narrowing portion recessed upward so as to engage with the second raised portion is formed in the mounting plate portion of the cover plate so as to reach the first narrowing portion; and the first narrowing portion is formed so as to reach the rear end of the mounting plate portion of the cover plate. A second invention of the present application is a stove with a grill, characterized by including the grill of the first invention.

[0008] According to the present invention (first invention), when installing a cover plate, the cover plate is positioned so that the mounting plate portion is placed on the burner cover, and the guide frame is positioned so that it engages with the laterally inner surface of the upper edge of the side plate portion of the cover plate. Then, the cover plate is pushed rearward. The first slit passes over the second raised portion located in the forward projection of the first raised portion. Finally, the first slit engages with the first raised portion, and the second slit engages with the second raised portion. This prevents lateral displacement of the mounting plate portion of the cover plate not only at the rear but also at the front. Therefore, lateral displacement of the front of the mounting plate portion of the cover plate does not cause the front upper edge of the side plate portion of the cover plate to slip below the guide frame, resulting in the cover plate falling off. The guide frame also prevents the cover plate from tipping laterally inward. Therefore, according to the present invention, the cover plate can be reliably installed simply by pushing it in while maintaining the correct position, improving the ease of installation.

[0009] Furthermore, in the present invention, it is desirable that the guide frame be provided only at the front end of the grill chamber. Here, grease and other substances splattered from the food being cooked adhere to the guide frame. Therefore, in order to reduce the amount of grease and other substances adhering to the guide frame, which is difficult to clean, it is preferable to shorten the guide frame. In particular, providing the guide frame only at the front end of the grill chamber not only allows the guide frame to be shortened, but also further improves cleanability because less grease and other substances splatter at the front end of the grill chamber. Furthermore, since the guide frame can be visually confirmed from the outside when attaching the cover plate, it is easy to align the cover plate with the guide frame, further improving the ease of attaching the cover plate.

[0011] The grill-equipped stove 1 shown in Figure 1 is a built-in type that can be incorporated into a system kitchen. This stove 1 is equipped with a pair of left and right stove burners 13, 13 as a stove heat source that are exposed on a top plate 12 that covers the top opening of the stove body 11. A trivet 14 is placed on the top plate 12 so as to surround each stove burner 13. In addition, an exhaust guard 15 that covers the grill exhaust port is placed on the rear of the top plate 12. A grill 2 according to an embodiment of the present invention is incorporated into the stove body 11.

[0012] 2 and 3, a grill 2 according to an embodiment of the present invention includes a grill compartment 3 with an open front, which is installed within the stove body 11, and a grill door 4 for opening and closing the front opening of the grill compartment 3. A grill pan 5 and a grill grate 6 above it are stored within the grill compartment 3. A sliding frame 41 extending rearward is connected to the grill door 4, and a pan support plate 42 for supporting the grill pan 5 is fixed to this sliding frame 41. Support frames 43 for supporting the grill grate 6 are erected in front of and behind the pan support plate 42. When the grill door 4 is opened forward, the grill pan 5 and the grill grate 6 are pulled out together to the front of the grill compartment 3.

[0013] An upper burner 7 is provided on the ceiling wall 31 of the grill chamber 3. The upper burner 7 is composed of a surface combustion burner having a ceramic or sheet metal combustion plate 71 with multiple flame holes (not shown) formed in it, and the upper burner 7 is attached to the ceiling wall 31 of the grill chamber 3 with the combustion plate 71 facing downward. An air-fuel mixture is supplied to the upper burner 7 from a mixing tube 72 provided at the rear of the upper burner 7.

[0014] The lower burners 8 of the present invention, which extend in the front-to-rear direction, are arranged at the bottom of both lateral sides of the grill chamber 3 (lower than the grill grate 6). The lower burners 8 have a plurality of flame ports 81 that open laterally inward, spaced apart in the front-to-rear direction. The lower burners 8 are also equipped with a spark plug 82 at the rear and a thermocouple 83 at the front.

[0015] Grill 2 further includes an exhaust passage 33 that extends rearward from the top of rear wall 32 of grill chamber 3. The rear of exhaust passage 33 is configured with exhaust duct 33a that rises diagonally upward toward the grill exhaust port at the rear of top plate 12 of grill stove 1. An afterburner 9 that burns off oily smoke contained in the combustion exhaust gas is located on the underside of exhaust passage 33. Afterburner 9 is configured as a surface combustion burner with a ceramic or sheet metal combustion plate 91 formed with multiple flame holes (not shown), and afterburner 9 is attached to the underside of exhaust passage 33 with combustion plate 91 facing upward.

[0016] 4 and 5, the grill 2 includes burner covers 35 that extend laterally inward from the side walls 34 on each lateral side of the grill chamber 3 to cover the lower burners 8, and a cover plate 36 that is detachably attached to the inside of the grill chamber 3 to cover the upper surface of the burner cover 35. The cover plate 36 includes a mounting plate portion 361 that is placed on the burner cover 35, and side plate portions 362 that extend upward from the lateral outer edges of the mounting plate portion 361 to cover the side walls 34 of the grill chamber 3. The upper portions 362a of the side plate portions 362 are inclined laterally inward. The upper portions 362a of the side plate portions 362 cover the lower portions of the downwardly inclined slopes 31a on both lateral sides of the ceiling wall 31 of the grill chamber 3.

[0017] An upwardly protruding first protrusion 351 is formed at the rear of the burner cover 35. An upwardly recessed first throttle portion 363 is formed at the rear of the mounting plate portion 361 of the cover plate 36. The first throttle portion 363 is recessed upward so as to engage with the first protrusion 351. The engagement of the first throttle portion 363 with the first protrusion 351 prevents the rear of the cover plate 36 from shifting laterally inward. The first throttle portion 363 is formed so as to reach the rear end of the mounting plate portion 361 of the cover plate 36.

[0018] The grill chamber 3 is also provided with a guide frame 37 that engages with the lateral inner surface of the upper edge of the side plate portion 362 of the cover plate 36 and guides the upper edge of the side plate portion 362 for forward and backward movement. The guide frame 37 can also be extended in the forward and backward directions. However, since grease and other substances scattered from the food being cooked adhere to the guide frame 37, it is preferable to shorten the guide frame 37 to reduce the amount of grease and other substances that adhere to the guide frame 37, which is difficult to clean. Therefore, in this embodiment, the guide frame 37 is provided only at the front end of the grill chamber 3. Specifically, the guide frame 37 is curved on the front frame 38 of the grill chamber 3, which surrounds the front opening of the grill chamber 3. The guide frame 37 may also be attached to the front end of the side wall 34 of the grill chamber 3 or the front end of the sloped portion 31a of the ceiling wall 31.

[0019] A second raised portion 352 that rises upward is formed in a portion of the burner cover 35 located forward of the first raised portion 351 and is positioned within a forward projection plane of the first raised portion 351. A second narrowed portion 364 that is recessed upward to engage with the second raised portion 352 is formed in the mounting plate portion 361 of the cover plate 36 so as to reach the first narrowed portion 363. In this embodiment, the widths of the second raised portion 352 and the second narrowed portion 364 are smaller than the widths of the first raised portion 351 and the first narrowed portion 363, but may be equal to the widths of the first raised portion 351 and the first narrowed portion 363. In this embodiment, the second raised portion 352 is spaced forward from the first raised portion 351, but may be continuous with the first raised portion 351. Furthermore, in this embodiment, the second narrowing portion 364 is formed so as to reach the front end of the mounting plate portion 361, but it may be formed so as to terminate at a position that coincides with the front end of the second protruding portion 352. In addition, a tongue portion 365 that protrudes forward is provided at the front end of the upper portion 362a of the side plate portion 362 of the cover plate 36 and serves as a handle when the cover plate 36 is pulled forward.

[0020] According to this embodiment, when attaching the cover plate 36, the cover plate 36 is positioned so that the mounting plate portion 361 is placed on the burner cover 35, and the guide frame 37 is positioned so that it engages with the lateral inner surface of the upper edge of the side plate portion 362 of the cover plate 36. Then, the cover plate 36 is pushed rearward. The first narrowed portion 363, which reaches the rear end of the mounting plate portion 361, passes over the second raised portion 352, which is located in the forward projection plane of the first raised portion 351, without interfering with the second raised portion 352. Note that, because the second narrowed portion 364 is continuous in front of the first narrowed portion 363, the front end of the first narrowed portion 363 does not get caught on the front end of the second raised portion 352. Finally, the first narrowed portion 363 engages with the first raised portion 351, and the second narrowed portion 364 engages with the second raised portion 352. This prevents lateral displacement of the mounting plate portion 361 of the cover plate 36 not only at the rear but also at the front. If the second protrusion 352 were not present and lateral displacement of the front portion of the mounting plate portion 361 of the cover plate 36 could not be prevented, the lateral displacement of the front portion of the mounting plate portion 361 of the cover plate 36 would cause the front upper edge of the side plate portion 362 of the cover plate 36 to slip out below the guide frame 37, potentially causing the cover plate 36 to fall off. However, in this embodiment, lateral displacement of the mounting plate portion 361 of the cover plate 36 is prevented not only at the rear but also at the front, so this problem does not occur. Furthermore, the guide frame 37 also prevents the cover plate 36 from tipping inward laterally. Therefore, according to this embodiment, the cover plate 36 can be securely attached simply by pushing it in while maintaining the correct orientation, improving the ease of attachment of the cover plate 36.

[0021] In addition, in this embodiment, the guide frame 37 is provided only at the front end of the grill chamber 3, where grease and the like are less likely to scatter, so the amount of grease and the like adhering to the guide frame 37 can be significantly reduced, further improving cleanability. Furthermore, when attaching the cover plate 36, the guide frame 37 can be visually confirmed from the outside, making it easier to align the cover plate 36 with the guide frame 37, further improving the ease of attaching the cover plate 36.

[0022] It is also possible to form downwardly recessed portions in the burner cover 35 instead of the first and second raised portions 351, 352, and to engage downwardly protruding portions formed on the mounting plate portion 361 of the cover plate 36 with these recessed portions to prevent lateral displacement of the mounting plate portion 361. However, this would cause the recessed portions to interfere with the flow of secondary air below the burner cover 35. In contrast, according to the above embodiment, the flow of secondary air below the burner cover 35 is advantageously not interfered with by the first and second raised portions 351, 352.

[0023] Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited thereto. For example, the grill 2 in the above embodiment is equipped with an upper burner 7 and an afterburner 9, but the present invention can also be applied to a grill without an upper burner or an afterburner, or to a grill equipped with a burner only on one lateral side of the grill chamber 3. Furthermore, the grill-equipped stove 1 in the above embodiment is equipped with a stove burner 13 as a stove heat source, but it may also be equipped with a stove heat source other than a stove burner, such as an induction heating coil.
