本発明は、被調理物を収容するグリル庫と、このグリル庫の天井部に設けられた上火バーナと、前記グリル庫の左右の両側壁の下方に設けられた下火バーナと、前記グリル庫に連設されて調理排気を上方の排気出口に案内する排気路とを備える両面焼きグリルに関する。 The present invention relates to a grill that accommodates an object to be cooked, an upper fire burner that is provided on the ceiling of the grill, a lower fire burner that is provided below the left and right side walls of the grill, and the grill The present invention relates to a double-sided grilling grill provided with an exhaust passage that is connected to a storage and guides cooking exhaust to an upper exhaust outlet.
この種のグリルは、被調理物としての魚などを焼網に並べて、グリル庫の天面に設けられた上バーナによる上からの加熱と、グリル庫の側壁に沿って設けられた左右両方の下バーナによる下からの加熱により被調理物を上下同時に加熱することで、調理途中で被調理物の上下を反転させる手間が省け効率よい調理を可能とするものである。（例えば、特許文献１参照。）。 This type of grill is made by arranging fish or other items to be cooked on a grill, heating from above with an upper burner provided on the top of the grill cabinet, and both left and right provided along the side walls of the grill cabinet. By heating the food to be cooked up and down simultaneously by heating from below with a lower burner, it is possible to save time and effort to invert the food to be cooked during cooking, thereby enabling efficient cooking. (For example, refer to Patent Document 1).
特許文献１などに示される両面焼きグリルでは、下火バーナは、グリル庫左右側壁下方に分かれて配置され、この下火バーナからの燃焼排気が焼網の下側を流れるようにして、被調理物の下面を焼くように構成されている。その際、下火バーナからの燃焼排気が焼網の中央付近まで流動しない場合には被調理物の下面に焼きムラが生じるため、下火バーナからの燃焼排気を焼網の中央付近まで流動させる必要があるが、近年、一度に調理できる被調理物の量の増加が望まれ、これに対応してグリル庫の左右寸法が大きくなる傾向、つまりグリル庫のワイド化が進み、グリル庫左右側壁下方に分かれて配置された下火バーナからの燃焼排気を焼網の中央付近まで流動させることが困難になってきている。 In the double-sided grill shown in Patent Document 1 or the like, the lower fire burner is arranged separately below the left and right side walls of the grill cabinet, and the combustion exhaust from the lower fire burner flows under the grill net to be cooked. It is configured to burn the lower surface of the object. At that time, if the combustion exhaust from the lower fire burner does not flow to the vicinity of the center of the grill net, uneven burning occurs on the lower surface of the cooking object, so the combustion exhaust from the lower fire burner flows to the vicinity of the center of the grill net. In recent years, it has been desired to increase the amount of food to be cooked at one time, and in response to this trend, the left and right dimensions of the grill have become larger. It has become difficult to flow the combustion exhaust from the lower fire burner arranged separately to the vicinity of the center of the grill.
これに対し、下火バーナの燃焼に用いられる燃焼用２次空気の流れを変更板などを用いて制御し、このように制御された燃焼用２次空気の流れによって下火バーナの炎を誘導することで、グリル庫のワイド化に対応して、グリル庫左右側壁下方に分かれて配置された下火バーナからの燃焼排気を焼網の中央付近まで流動させることは可能である。 On the other hand, the flow of the secondary air for combustion used for the combustion of the lower fire burner is controlled using a change plate or the like, and the flame of the lower fire burner is induced by the flow of the secondary air for combustion thus controlled. By doing so, it is possible to cause the combustion exhaust from the lower fire burner arranged separately below the left and right side walls of the grill to flow to the vicinity of the center of the grill net corresponding to the widening of the grill.
しかしながら、変更板などによって燃焼用２次空気の流れを制御する場合においては、燃焼用２次空気の流れによって下火バーナの炎を焼網の中央付近まで誘導するものであるから、下火バーナの炎の誘導に十分な量の２次空気の流れが必要であり、下火バーナの炎の誘導に用いられる２次空気の量は下火バーナの燃焼に必要な２次空気の量より多くなりがちであり、その結果、この過剰な２次空気が下火バーナや上火バーナーに供給される虞があるもので、上火バーナや下火バーナに過剰な空気を供給してしまった場合には、上火バーナや下火バーナからの燃焼排気の温度低下に起因してエネルギ消費効率が低下する虞があった。 However, when the flow of the secondary air for combustion is controlled by a change plate or the like, the flame of the lower flame burner is guided to the vicinity of the center of the grill by the flow of the secondary air for combustion. A sufficient amount of secondary air flow is required to induce the flame, and the amount of secondary air used to induce the flame of the lower burner is greater than the amount of secondary air required to burn the lower flame burner. As a result, there is a possibility that this excessive secondary air may be supplied to the lower fire burner or the upper fire burner, and if excessive air is supplied to the upper fire burner or the lower fire burner. In this case, there is a concern that the energy consumption efficiency may be lowered due to the temperature drop of the combustion exhaust from the upper fire burner or the lower fire burner.
本発明は、上記課題を解決するものであり、下火バーナの燃焼排気がグリル庫中央まで届いて、被調理物の下面の焼きムラが生じ難く、かつ、下火バーナや上火バーナへの過剰な空気の供給が抑制され、エネルギ消費効率の低下が抑制された両面焼きグリルを提供することを目的とする。 The present invention solves the above-mentioned problem, and the combustion exhaust of the lower-burner burner reaches the center of the grill cabinet, so that uneven baking on the lower surface of the object to be cooked hardly occurs, and the lower-burner burner and the upper-burner burner are not affected. An object of the present invention is to provide a double-sided grill that suppresses excessive air supply and suppresses reduction in energy consumption efficiency.
本発明に係る両面焼きグリルは、被調理物を収容するグリル庫と、このグリル庫の天井部に設けられた上火バーナと、前記グリル庫の左右の両側壁の下方に設けられた下火バーナと、前記グリル庫に連設されて調理排気を上方の排気出口に案内する排気路とを備える両面焼きグリルにおいて、
その第１特徴構成は、前記排気路の入口を仕切って前記調理排気を上側通流排気と下側通流排気とに分流する仕切り板を設け、前記下側通流排気を前記排気出口に向けて案内する第２排気路が形成されており、前記第２排気路の出口から排出される前記下側通流排気が、前記排気路中または前記排気出口を通流する前記上側通流排気の流れの中において前記上側通流排気の通流方向に沿って排出されるように、前記第２排気路の出口が配設され、前記第２排気路の出口の周縁から外方に、鍔部が形成される点にある。
The double-sided grill according to the present invention includes a grill storage for storing an object to be cooked, an upper fire burner provided at the ceiling of the grill storage, and a lower fire provided below the left and right side walls of the grill storage. In a double-sided grill comprising a burner and an exhaust passage that is connected to the grill cabinet and guides cooking exhaust to an upper exhaust outlet,
The first characteristic configuration includes a partition plate that partitions the inlet of the exhaust passage and divides the cooking exhaust into an upper exhaust and a lower exhaust, and directs the lower exhaust to the exhaust outlet. A second exhaust passage is formed to guide the lower flow exhaust discharged from the outlet of the second exhaust passage to the upper flow exhaust passing through the exhaust passage or the exhaust outlet. An outlet of the second exhaust passage is disposed so as to be discharged along a flow direction of the upper-side exhaust in the flow, and the flange portion extends outward from a peripheral edge of the outlet of the second exhaust passage. there is a point that will be formed.
第１特徴構成によれば、下側通流排気を前記排気出口に向けて案内する第２排気路が形成されることによって、グリル庫の左右の両側壁の下方に設けられた下火バーナからの燃焼排気が焼網の下側の中央部分まで届くようになるので、被調理物の下側からの加熱の熱分布が良くなり、調理性能が向上する。 According to the first characteristic configuration, the second exhaust passage that guides the lower flow exhaust toward the exhaust outlet is formed, so that the lower fire burner provided below the left and right side walls of the grill cabinet Since the combustion exhaust gas reaches the central portion on the lower side of the grill, the heat distribution of the heating from the lower side of the cooking object is improved, and the cooking performance is improved.
つまり、仕切り板の下側を通流する下側通流排気を排気出口に向けて案内する第２排気路が形成された場合には、主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気と、上火バーナからの燃焼排気からなる調理排気が多く含まれる上側通流排気とが、調理排気を上方の排気出口に案内する排気路において合流することが抑制されて、上記下側通流排気が第２排気路を通って排気出口に向けて案内されるから、主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気の流れが、上火バーナからの燃焼排気からなる調理排気が多く含まれる上側通流排気の流れによって邪魔されることなしに、主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気が排気出口に向けて案内される。これによって、下側通流排気の流れが促進されて、下火バーナからの燃焼排気が焼網の下側の中央部分まで届くようになるものである。 That is, when the second exhaust passage that guides the lower flow exhaust that flows through the lower side of the partition plate toward the exhaust outlet is formed, the cooked exhaust mainly composed of the combustion exhaust from the lower fire burner is generated. It is suppressed that the lower flow exhaust included and the upper flow exhaust including a large amount of cooking exhaust including combustion exhaust from the upper fire burner are joined in the exhaust path that guides the cooking exhaust to the upper exhaust outlet. Thus, since the lower flow exhaust is guided toward the exhaust outlet through the second exhaust passage, the flow of the lower flow exhaust including the cooked exhaust mainly consisting of the combustion exhaust from the lower fire burner is generated. The lower flow that mainly contains the cooked exhaust consisting of combustion exhaust from the lower fire burner without being disturbed by the flow of the upper flow exhaust that contains the combustion exhaust consisting of combustion exhaust from the upper fire burner. The exhaust is guided toward the exhaust outlet. As a result, the flow of the lower flow exhaust is promoted so that the combustion exhaust from the lower fire burner reaches the lower central portion of the grill.
一方、第２排気路が形成されない場合は、主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気と、上火バーナからの燃焼排気からなる調理排気が多く含まれる上側通流排気とが、調理排気を上方の排気出口に案内する排気路において合流する際に、下側通流排気の流れのベクトルと上側通流排気の流れのベクトルの内、お互いに直交する流れ成分同士が干渉して圧力損失を生じることになり、下側通流排気の通流は上側通流排気によって邪魔され抑制されることになる。 On the other hand, when the second exhaust path is not formed, the lower side exhaust gas mainly including the cooked exhaust gas composed of the combustion exhaust from the lower fire burner and the cooked exhaust gas composed of the combustion exhaust gas from the upper fire burner are mainly included. When the upper circulated exhaust gas joins in the exhaust passage that guides the cooked exhaust gas to the upper exhaust outlet, the lower circulated exhaust gas flow vector and the upper circulated exhaust gas flow vector are orthogonal to each other. The flow components interfere with each other to cause a pressure loss, and the flow of the lower flow exhaust is disturbed and suppressed by the upper flow exhaust.
因みに、第１特徴構成によって必要以上に下火バーナからの燃焼排気がグリル庫の中央側に延びすぎる場合は、下火バーナに２次空気を供給する空気供給孔の面積を減少させるなどによって容易に適正な状態に調整可能であり、過剰な空気の供給が抑制され、エネルギ消費効率の低下が抑制されることになる。 Incidentally, when the combustion exhaust from the lower fire burner extends to the center side of the grill warehouse more than necessary due to the first characteristic configuration, it is easy by reducing the area of the air supply hole for supplying secondary air to the lower fire burner. Therefore, it is possible to adjust to an appropriate state, the supply of excess air is suppressed, and the decrease in energy consumption efficiency is suppressed.
要するに、第１特徴構成によって、グリル庫の左右の両側壁の下方に設けられた下火バーナからの燃焼排気が焼網の下側の中央部分まで届くようになるので、被調理物の下側からの加熱の熱分布が良くなり、調理性能が向上すると共に、過剰な空気の供給を抑制することも可能で、エネルギ消費効率の低下の抑制も可能となる。 In short, the first characteristic configuration allows the combustion exhaust from the lower fire burner provided below the left and right side walls of the grill to reach the lower central part of the grill net, so The heat distribution from the heating is improved, cooking performance is improved, supply of excess air can be suppressed, and reduction in energy consumption efficiency can also be suppressed.
本発明の第１特徴構成には、前記第２排気路の出口から排出される前記下側通流排気が、前記排気路中または前記排気出口を通流する前記上側通流排気の流れの中において前記上側通流排気の通流方向に沿って排出されるように、前記第２排気路の出口が配設される点を含む。 In the first characteristic configuration of the present invention, the lower flow exhaust discharged from the outlet of the second exhaust passage is in the flow of the upper flow exhaust passing through the exhaust passage or the exhaust outlet. as is discharged along the flow direction of the upper through-flow exhaust at, including a point of exit of the second exhaust path is provided.
第１特徴構成によれば、主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気が、前記第２排気路の出口において、上火バーナからの燃焼排気からなる調理排気が多く含まれる上側通流排気の通流方向に沿って排出されることで、第２排気路中を通流する下側通流排気の通流が促進されて、下側通流排気に含まれる下火バーナからの燃焼排気のグリル庫の中央側への延びがさらに促進される。この場合も、必要以上に下火バーナからの燃焼排気がグリル庫の中央側に延びすぎる場合は、下火バーナに２次空気を供給する空気供給孔の面積を減少させるなどによって容易に適正な状態に調整可能であり、過剰な空気の供給は抑制可能であり、エネルギ消費効率の低下を抑制することが可能である。 According to the first characteristic configuration , the lower flow exhaust including mainly the cooking exhaust made from the combustion exhaust from the lower fire burner is cooked from the combustion exhaust from the upper fire burner at the outlet of the second exhaust passage. By discharging along the flow direction of the upper flow exhaust gas containing a large amount of exhaust gas, the flow of the lower flow exhaust gas flowing through the second exhaust passage is promoted, and the lower flow exhaust gas is changed to the lower flow exhaust gas. The extension of the combustion exhaust from the included lower fire burner to the center side of the grill is further promoted. Also in this case, if the combustion exhaust from the lower fire burner extends to the center side of the grill warehouse more than necessary, it is possible to easily adjust the air supply hole to the lower fire burner by reducing the area of the air supply hole. It is possible to adjust to a state, supply of excess air can be suppressed, and reduction in energy consumption efficiency can be suppressed.
要するに、第１特徴構成によって、被調理物の下側からの加熱の熱分布がさらに良くなり、調理性能が向上すると共に、過剰な空気の供給を抑制することも可能で、エネルギ消費効率の低下の抑制も可能となる。 In short, the first characteristic configuration further improves the heat distribution of heating from the underside of the object to be cooked, improves the cooking performance, and can suppress the supply of excess air, resulting in a reduction in energy consumption efficiency. Can also be suppressed.
本発明の第１特徴構成には、前記第２排気路の出口の周縁から外方に、鍔部が形成される点を含む。 The first characteristic configuration of the present invention includes a point where a flange portion is formed outward from the peripheral edge of the outlet of the second exhaust path.
第１特徴構成によれば、鍔部の外周側を流れる主に上火バーナからの燃焼排気からなる調理排気が含まれる上側通流排気の通流によって、鍔部の下流側に負圧帯が形成され、この負圧帯に向かって主に下火バーナからの燃焼排気からなる調理排気が含まれる下側通流排気が引き込まれることによって、第２排気路中を通流する下側通流排気の通流がさらに促進されて、下側通流排気に含まれる下火バーナからの燃焼排気のグリル庫の中央側への延びが一層促進される。この場合も、必要以上に下火バーナからの燃焼排気がグリル庫の中央側に延びすぎる場合は、下火バーナに２次空気を供給する空気供給孔の面積を減少させるなどによって容易に適正な状態に調整可能であり、過剰な空気の供給は抑制可能であり、エネルギ消費効率の低下を抑制することが可能である。 According to the first characteristic configuration , a negative pressure zone is formed on the downstream side of the buttock due to the flow of the upper circulated exhaust including cooking exhaust mainly composed of combustion exhaust from the upper fire burner that flows on the outer peripheral side of the buttock. A lower-side flow that is formed and flows through the second exhaust path by drawing in the lower-passage exhaust that includes cooking exhaust mainly composed of combustion exhaust from the lower fire burner toward the negative pressure zone. The flow of the exhaust is further promoted, and the extension of the combustion exhaust from the lower fire burner included in the lower flow exhaust to the center of the grill is further promoted. Also in this case, if the combustion exhaust from the lower fire burner extends to the center side of the grill warehouse more than necessary, it is possible to easily adjust the air supply hole to the lower fire burner by reducing the area of the air supply hole. It is possible to adjust to a state, supply of excess air can be suppressed, and reduction in energy consumption efficiency can be suppressed.
要するに、第１特徴構成によって、被調理物の下側からの加熱の熱分布が一層良くなり、調理性能が向上すると共に、過剰な空気の供給を抑制することも可能で、エネルギ消費効率の低下の抑制も可能となる。 In short, with the first characteristic configuration , the heat distribution of heating from the underside of the object to be cooked is further improved, cooking performance is improved, and it is also possible to suppress the supply of excess air, reducing energy consumption efficiency. Can also be suppressed.
本発明の第２特徴構成は、第１特徴構成に加えて、前記第２排気路が、前記第２排気路の出口を通して落下侵入した異物を受止め滞留させない状態で設けられている点にある。 The second characteristic configuration of the present invention is that, in addition to the first characteristic configuration, the second exhaust path is provided in a state in which foreign matter dropped and invaded through the outlet of the second exhaust path is not received and retained. .
第２特徴構成によれば、第２排気路が、前記第２排気路の出口を通して落下侵入した異物を受止め滞留させない状態で設けられているから、第２排気路の出口を通して落下侵入した異物は、第２排気路内部で受止められて堆積することがなく第２排気路の入口を通してグリル庫に通過するのであり、第２排気路に詰まりが生じることがなく、第２排気路の入口を通してグリル庫に通過した異物はグリル庫に通常備える被調理物出し入れ用の開口部を通して容易に除去することができる。 According to the second characteristic configuration , since the second exhaust path is provided in a state in which the foreign matter that has fallen and entered through the outlet of the second exhaust path is not received and retained, the foreign substance that has fallen and entered through the outlet of the second exhaust path. Is received inside the second exhaust passage and does not accumulate, and passes through the inlet of the second exhaust passage to the grill box, so that the second exhaust passage is not clogged and the inlet of the second exhaust passage. The foreign matter that has passed through the grill can be easily removed through the opening for taking in and out the food that is usually provided in the grill.
要するに、第２特徴構成によって、清掃性に優れた両面焼きグリルとすることができる。 In short, the double-sided grill with excellent cleanability can be obtained by the second characteristic configuration .
本発明の第３特徴構成は、第１特徴構成または第２特徴構成のいずれかに加えて、平面視において前記第２排気路の出口が前記排気出口の領域内に設けられ、前記第２排気路の外周と前記排気路の内周との間に防塵部材が備えられている点にある。 According to a third feature configuration of the present invention, in addition to either the first feature configuration or the second feature configuration , an outlet of the second exhaust path is provided in a region of the exhaust outlet in a plan view, and the second exhaust A dustproof member is provided between the outer periphery of the path and the inner periphery of the exhaust path.
第３特徴構成によれば、第２排気路の外周と排気路の内周との間から落下した異物の排気路への浸入が防止できるので、異物による排気路の閉塞が防止でき、異物による排気路の閉塞に起因する不都合の発生が抑制される。 According to the third feature configuration , foreign matter dropped from between the outer periphery of the second exhaust passage and the inner periphery of the exhaust passage can be prevented from entering the exhaust passage, so that the exhaust passage can be prevented from being blocked by the foreign matter. The occurrence of inconvenience due to the blockage of the exhaust passage is suppressed.
つまり、第３特徴構成によって、信頼性の高い両面焼きグリルとすることができる。 That is, by the third feature configuration , a highly reliable double-sided grill can be obtained.
本発明の第４特徴構成は、第３特徴構成に加えて、前記防塵部材が通気孔を多数備えた多孔状体にて構成されている点にある。
第４特徴構成によれば、前記第２排気路の外周と前記排気路の内周との間に備える防塵部材を、万が一グリル庫内において被調理物が発火した場合にも、被調理物の発火によって形成された炎が前記第２排気路の外周と前記排気路の内周との間を通って排気路から外に伸びることを防止する消炎部材として兼用できるので、両面焼きグリルの製造コストが低減できる。
According to a fourth characteristic configuration of the present invention, in addition to the third characteristic configuration , the dustproof member is configured by a porous body having a large number of ventilation holes.
According to the fourth characteristic configuration , the dust-proof member provided between the outer periphery of the second exhaust path and the inner periphery of the exhaust path is provided with the object to be cooked even if the object to be cooked ignites in the grill cabinet. Since the flame formed by the ignition can be used as a flame extinguishing member that prevents the flame from extending from the exhaust passage through between the outer periphery of the second exhaust passage and the inner periphery of the exhaust passage, the manufacturing cost of the double-sided grill Can be reduced.
つまり、万が一グリル庫内において被調理物が発火した場合には、調理物の発火によって形成される炎は、排気路の入口を仕切って前記調理排気を上側通流排気と下側通流排気とに分流する仕切り板の上側を通って排気路から外に伸びようとすることになるが、第２排気路の外周と前記排気路の内周との間には、通気孔を多数備えた多孔状体にて構成される防塵部材を備えるので、被調理物の発火によって形成された炎が、多孔状体に多数備える通気孔を通過しようとする際に炎の温度が低下して、いわゆるクエンチング効果によって消炎することになり、消炎部材を防塵部材と別体に備える必要がなく、両面焼きグリルの製造コストが低減できる。 In other words, in the unlikely event that the food to be ignited in the grill cabinet, the flame formed by the ignition of the food is divided into an inlet of the exhaust passage, and the cooking exhaust is divided into an upper exhaust and a lower exhaust. However, the porous plate is provided with a large number of vent holes between the outer periphery of the second exhaust passage and the inner periphery of the exhaust passage. Since a dust-proof member composed of a body is provided, the temperature of the flame decreases when the flame formed by the ignition of the object to be cooked tries to pass through the air holes provided in the porous body, so-called quenching. The flame is extinguished by the ching effect, and it is not necessary to provide the flame extinguishing member separately from the dustproof member, and the manufacturing cost of the double-sided grill is reduced.
本発明の第５特徴構成は、第４特徴構成に加えて、前記防塵部材に酸化触媒を担持させた点にある。 A fifth characteristic configuration of the present invention is that, in addition to the fourth characteristic configuration , an oxidation catalyst is supported on the dustproof member.
第５特徴構成によれば、防塵部材が、例えば白金やパラジウム等からなる酸化触媒を担持させた多孔状体にて構成されることになり、グリル庫にて発生する調理排気が消炎部材を兼ねる防塵部材を構成する多孔状体における多数の通気孔を通過する際に、その調理排気中に含まれる臭い成分や未燃成分が酸化触媒によって酸化処理されて、調理排気が浄化した状態で外部に排出されることになる。 According to the fifth characteristic configuration , the dust-proof member is constituted by a porous body that supports an oxidation catalyst made of, for example, platinum or palladium, and cooking exhaust generated in the grill is also used as a flame-extinguishing member. When passing through a large number of ventilation holes in the porous body constituting the dustproof member, the odorous components and unburned components contained in the cooking exhaust are oxidized by the oxidation catalyst, and the cooking exhaust is purified outside. Will be discharged.
因みに、調理排気中に含まれる臭い成分や未燃成分は主に魚などの被調理物から発生するものであるから、調理排気中に含まれる臭い成分や未燃成分は一般的に被調理物が載置される焼き網よりも上方において発生し、調理排気中に含まれる臭い成分の多くは調理排気を上側通流排気と下側通流排気とに分流する仕切り板の上側を通って排気路から排出されることになるので、防塵部材による浄化作用を有らしめ易く好都合である。 Incidentally, odorous components and unburned components contained in cooking exhaust are mainly generated from cooked items such as fish, so odorous components and unburned components contained in cooking exhaust are generally cooked items. Most of the odorous components contained in the cooking exhaust are exhausted through the upper side of the partition plate that divides the cooking exhaust into the upper flow exhaust and the lower flow exhaust.

なお、本発明の第１実施形態として、グリル付ガステーブルコンロに備える両面焼きグリル４０を一例として説明するが、本発明はグリル付ガステーブルコンロに備える両面焼きグリルに限定されるものではなく、キッチンカウンターの上部に設けた開口に設置されるドロップインタイプのガスコンロに備える両面焼きグリルやコンロ等に内蔵されない両面焼きグリルに対しても適用可能である。 As a first embodiment of the present invention, a double-sided grill 40 provided in a gas table stove with a grill will be described as an example, but the present invention is not limited to a double-sided grill provided in a gas table stove with a grill. The present invention can also be applied to a double-sided grill provided in a drop-in type gas stove installed in an opening provided in the upper part of the kitchen counter or a double-sided grill not incorporated in a stove.
図２に示すように、両面焼きグリル４０は、グリル庫３０に備える焼き網３３上に被調理物３４を載置し収容して、グリル庫３０の天井部に設けられた上火バーナ３２ａによって主に被調理物３４の上面を加熱し、前記グリル庫３０の左右の両側壁の下方に設けられた下火バーナ３２ｂによって主に被調理物３４の下面を加熱し、被調理物３４の上下両面を同時に加熱する両面焼き調理を行う。調理によって被調理物３４から落下する焼き汁は、焼き網３３の下に備えるグリル皿３７によって受け止められる。 As shown in FIG. 2, the double-sided grill 40 has the cooking object 34 placed and accommodated on a grill 33 provided in the grill cabinet 30, and an upper fire burner 32 a provided on the ceiling of the grill cabinet 30. The upper surface of the cooking object 34 is mainly heated, the lower surface of the cooking object 34 is mainly heated by the lower fire burners 32b provided below the left and right side walls of the grill cabinet 30, and the upper and lower surfaces of the cooking object 34 are heated. Double-sided baked cooking that heats both sides simultaneously. The broth falling from the cooking object 34 by cooking is received by the grill pan 37 provided under the grill 33.
また、グリル庫３０の両側壁において下火バーナ３２ｂの下側に固定された固定レール（図示せず）に対してスライド自在に構成されたスライドレール３５にグリル皿３７の左右端が取り付けられており、グリル扉取っ手４４を把持して前後に移動操作することで、グリル皿３７は、その上に載置された焼き網３３と共に、グリル庫３０内への収納およびグリル庫３０からの引き出し自在に構成されている。 In addition, the left and right ends of the grill pan 37 are attached to slide rails 35 slidable with respect to a fixed rail (not shown) fixed to the lower side of the lower fire burner 32 b on both side walls of the grill cabinet 30. The grill pan 37 can be stored in and pulled out of the grill cabinet 30 together with the grill 33 placed on the grill pan 37 by gripping the grill door handle 44 and moving it back and forth. It is configured.
図３に示すように、上火バーナ３２ａに供給される燃料ガスＧの燃焼によって上火バーナ３２ａの燃焼排気３６ａが生成され、下火バーナ３２ｂに供給される燃料ガスＧの燃焼によって下火バーナ３２ｂの燃焼排気３６ｂが生成される。上火バーナ３２ａの燃焼排気３６ａおよび下火バーナ３２ｂの燃焼排気３６ｂは、調理排気として、グリル庫３０の後部においてグリル庫３０に連設された排気路５１を通って天板１３（図１参照。）に設けられた排気出口４５に案内されて機外に排出される。なお、図３においては、グリル皿３７および被調理物３４の記載を省略してある。因みに、後述する図６、図７、図８においても、グリル皿３７および被調理物３４の記載を省略してある。 As shown in FIG. 3, the combustion exhaust 36a of the upper fire burner 32a is generated by the combustion of the fuel gas G supplied to the upper fire burner 32a, and the lower fire burner is generated by the combustion of the fuel gas G supplied to the lower fire burner 32b. A combustion exhaust 36b of 32b is generated. The combustion exhaust 36a of the upper fire burner 32a and the combustion exhaust 36b of the lower fire burner 32b pass through an exhaust passage 51 provided continuously to the grill warehouse 30 at the rear part of the grill warehouse 30 as cooking exhaust gas (see FIG. 1). .)) And is discharged outside the machine. In addition, in FIG. 3, description of the grill pan 37 and the to-be-cooked object 34 is abbreviate | omitted. Incidentally, also in FIG. 6, FIG. 7, and FIG. 8 to be described later, description of the grill pan 37 and the cooked object 34 is omitted.
図３に示すように、グリル庫３０に連設される排気路５１の入口は仕切り板５３によって上下に仕切られている。仕切り板５３は、上火バーナ３２ａの燃焼排気３６ａおよび下火バーナ３２ｂの燃焼排気３６ｂからなる調理排気を仕切り板５３の上側を通流する上側通流排気３８と、仕切り板５３の下側を通流する下側通流排気３９とに、上下に分流する。 As shown in FIG. 3, the inlet of the exhaust passage 51 connected to the grill warehouse 30 is partitioned vertically by a partition plate 53. The partition plate 53 includes an upper flow exhaust 38 through which the cooked exhaust gas composed of the combustion exhaust 36 a of the upper fire burner 32 a and the combustion exhaust 36 b of the lower fire burner 32 b flows and the lower side of the partition plate 53. The gas is diverted up and down to the lower flow exhaust 39 that flows.
グリル庫３０から排出される調理排気のうち、上火バーナ３２ａの燃焼排気３６ａのほとんどは仕切り板５３の上側を通流する上側通流排気３８となり、下火バーナ３２ｂの燃焼排気３６ｂの多くの部分が、仕切り板５３の下側を通流する下側通流排気３９となる。なお、上側通流排気３８には、下火バーナ３２ｂの燃焼排気３６ｂの内、焼き網３３を下側から上側に通過したものが含まれる。また、下側通流排気３９には、グリル皿３７（図２参照。）の冷却用に通流される空気も含まれる。 Of the cooked exhaust discharged from the grill warehouse 30, most of the combustion exhaust 36a of the upper fire burner 32a becomes the upper flow exhaust 38 flowing through the upper side of the partition plate 53, and much of the combustion exhaust 36b of the lower fire burner 32b. The portion becomes the lower flow exhaust 39 that flows through the lower side of the partition plate 53. The upper exhaust gas 38 includes the exhaust gas 36b of the lower fire burner 32b that has passed through the grill 33 from the lower side to the upper side. Further, the lower flow exhaust 39 includes air that is flowed for cooling the grill pan 37 (see FIG. 2).
排気路５１内には、下側通流排気３９を排気出口４５に向けて案内する第２排気路５２が形成してある。切り板５３の下側を通流する下側通流排気３９を排気出口４５に向けて案内する第２排気路５２が形成されていることによって、主に下火バーナ３２ｂからの燃焼排気３６ｂからなる調理排気が含まれる下側通流排気３９と、上火バーナ３２ａからの燃焼排気３６ａからなる調理排気が多く含まれる上側通流排気３８とが、調理排気を上方の排気出口４５に案内する排気路５１の入り口付近乃至中間位置付近の区間において合流することが抑制されて、下側通流排気３９は第２排気路５２を通って排気出口４５に向けて案内される。 A second exhaust passage 52 that guides the lower flow exhaust 39 toward the exhaust outlet 45 is formed in the exhaust passage 51. By forming the second exhaust passage 52 that guides the lower flow exhaust 39 that flows through the lower side of the cutting plate 53 toward the exhaust outlet 45, the combustion exhaust 36b mainly from the lower fire burner 32b is formed. The lower flow exhaust 39 including the cooked exhaust and the upper flow exhaust 38 including a large amount of the cooked exhaust 36a from the upper fire burner 32a guide the cooked exhaust to the upper exhaust outlet 45. The merging in the section from the vicinity of the entrance to the intermediate position of the exhaust passage 51 is suppressed, and the lower flow exhaust 39 is guided toward the exhaust outlet 45 through the second exhaust passage 52.
第２排気路５２を備えることによって、主に下火バーナ３２ｂからの燃焼排気３６ｂからなる調理排気が含まれる下側通流排気３９の流れが、上火バーナ３２ａからの燃焼排気３６ａからなる調理排気が多く含まれる上側通流排気３８の流れによって円滑な通流を乱されることなしに、主に下火バーナ３２ｂからの燃焼排気３６ｂからなる調理排気が含まれる下側通流排気３９が排気出口４５に向けて円滑に案内される。これによって、下側通流排気３９の流れが促進されて、下火バーナ３２ｂからの燃焼排気３６ｂが焼き網３３の下側の中央部分まで届くようにしてあり、被調理物３４の下面に焼きムラが生じることが抑制されて被調理物３４の下面が均一に焼きあがる。 By providing the second exhaust passage 52, the flow of the lower flow exhaust 39 mainly including the cooking exhaust 36b composed of the combustion exhaust 36b from the lower fire burner 32b becomes the cooking composed of the combustion exhaust 36a from the upper fire burner 32a. The lower flow exhaust 39 including the cooked exhaust mainly composed of the combustion exhaust 36b from the lower fire burner 32b is obtained without disturbing the smooth flow by the flow of the upper flow exhaust 38 containing a large amount of exhaust. It is guided smoothly toward the exhaust outlet 45. As a result, the flow of the lower flow exhaust 39 is promoted so that the combustion exhaust 36b from the lower fire burner 32b reaches the lower central portion of the grill 33, and the lower surface of the cooking object 34 is baked. The occurrence of unevenness is suppressed and the lower surface of the object to be cooked 34 is baked uniformly.
本実施形態においては、第２排気路５２は、排気路５１内に形成してあるが、下側通流排気３９を排気出口４５に向けて案内するものであれば、排気路５１内に形成することに限定されず、第２排気路５２を排気路５１の外に形成してもよい。 In the present embodiment, the second exhaust passage 52 is formed in the exhaust passage 51. However, the second exhaust passage 52 is formed in the exhaust passage 51 as long as it guides the lower flow exhaust 39 toward the exhaust outlet 45. However, the second exhaust path 52 may be formed outside the exhaust path 51.
なお、第１実施形態では第２排気路５２の出口が排気出口４５よりも高い位置に配置され、第２排気路５２の出口から排出された下側通流排気３９ｅが、排気出口４５を通流する上側通流排気３８ｅの流れの中において上側通流排気３８ｅの通流方向に沿って排出されるように、第２排気路５２の出口を配設してある。これによって、主に下火バーナ３２ｂからの燃焼排気３６ｂからなる調理排気が含まれる下側通流排気３９が、第２排気路５２の出口において、上火バーナ３２ａからの燃焼排気３６ａからなる調理排気が多く含まれる、排気出口４５を通流する上側通流排気３８ｅの通流方向に沿って排出されることで、第２排気路５２中を通流する下側通流排気３９の通流が促進されて、下火バーナ３２ｂの燃焼排気３６ｂのグリル庫３０の中央側への延びがさらに促進される。 In the first embodiment, the outlet of the second exhaust passage 52 is disposed at a position higher than the exhaust outlet 45, and the lower flow exhaust 39 e discharged from the outlet of the second exhaust passage 52 passes through the exhaust outlet 45. The outlet of the second exhaust passage 52 is disposed so as to be discharged along the flow direction of the upper flow exhaust 38e in the flowing flow of the upper flow exhaust 38e. As a result, the lower flow exhaust 39 including the cooked exhaust mainly consisting of the combustion exhaust 36b from the lower fire burner 32b becomes the cooking consisting of the combustion exhaust 36a from the upper fire burner 32a at the outlet of the second exhaust passage 52. The flow of the lower flow exhaust 39 flowing through the second exhaust passage 52 by being discharged along the flow direction of the upper flow exhaust 38e flowing through the exhaust outlet 45, which contains a large amount of exhaust. And the extension of the combustion exhaust 36b of the lower fire burner 32b to the center side of the grill 30 is further promoted.
また、第２排気路５２は、第２排気路５２の出口を通して落下侵入した異物を受止め滞留させない状態で設けられている。具体的には、第２排気路５２は、垂直姿勢で直管状に設けられている。このように、第２排気路５２が、第２排気路５２の出口を通して落下侵入した異物を受止め滞留させない状態で設けられているから、第２排気路５２の出口を通して落下侵入した異物は、第２排気路５２内部で受止められて堆積することがなく第２排気路５２の入口を通してグリル庫３０に通過するのであり、第２排気路５２に詰まりが生じることがなく、第２排気路５２の入口を通してグリル庫３０に通過した異物はグリル庫３０に通常備える被調理物３４出し入れ用の開口部を通して容易に除去することができる。 Further, the second exhaust path 52 is provided in a state in which foreign matter that has fallen and entered through the outlet of the second exhaust path 52 is not received and retained. Specifically, the second exhaust passage 52 is provided in a straight tube shape in a vertical posture. Thus, since the second exhaust path 52 is provided in a state where it does not receive and retain the foreign matter that has fallen and entered through the outlet of the second exhaust path 52, the foreign matter that has fallen and entered through the outlet of the second exhaust path 52 is The second exhaust path 52 passes through the inlet of the second exhaust path 52 to the grill 30 without being received and accumulated inside the second exhaust path 52, and the second exhaust path 52 is not clogged, and the second exhaust path The foreign matter that has passed through the entrance of 52 to the grill cabinet 30 can be easily removed through the opening for taking in and out the food 34 that is normally provided in the grill cabinet 30.
これに対し、第２排気路５２が、第２排気路５２の出口を通して落下侵入した異物を受止め滞留させる形状、例えば、第２排気路５２の途中にＵ字状に下に凸になる曲がり箇所を有する場合や、第２排気路５２の途中に略水平箇所を有する場合には、これらＵ字状に下に凸になる曲がり箇所や略水平箇所に第２排気路５２の出口を通して落下侵入した異物が受け止められて堆積する虞があるため、堆積した異物を取り除き清掃するための構造を別途構成する必要があるが、本実施形態では、第２排気路５２に異物が堆積することがないため堆積した異物を取り除き清掃するための構造を別途構成する必要がなく、低コストで高信頼性を得ている。なお、第２排気路５２の形状は、第２排気路５２の出口を通して落下侵入した異物を受止め滞留させない形状であればよく、直管状の形状に限定されるものではない。 On the other hand, the second exhaust passage 52 is configured to receive and retain foreign matter that has fallen and entered through the outlet of the second exhaust passage 52, for example, a curve that protrudes downward in a U shape in the middle of the second exhaust passage 52. If there is a portion, or if there is a substantially horizontal portion in the middle of the second exhaust passage 52, the U-shaped bent portion that protrudes downward or a substantially horizontal portion will fall through the outlet of the second exhaust passage 52 and enter. Therefore, it is necessary to separately configure a structure for removing the accumulated foreign matter and cleaning it. However, in this embodiment, the foreign matter does not accumulate in the second exhaust path 52. Therefore, it is not necessary to separately construct a structure for removing accumulated foreign matter and cleaning, and high reliability is obtained at low cost. The shape of the second exhaust passage 52 is not limited to a straight tubular shape as long as the foreign matter that has fallen and entered through the outlet of the second exhaust passage 52 is not received and retained.
図１、図３に示すように、平面視において第２排気路５２の出口は、排気出口４５の領域内に設けられ、第２排気路５２の外周と排気路５１の内周との間に防塵部材５５を備えている。 As shown in FIGS. 1 and 3, the outlet of the second exhaust passage 52 is provided in the region of the exhaust outlet 45 in a plan view, and between the outer periphery of the second exhaust passage 52 and the inner periphery of the exhaust passage 51. A dustproof member 55 is provided.
防塵部材５５を備えていることによって、第２排気路５２の外周と排気路５１の内周との間から落下した異物の排気路５１への侵入が防止できるので、異物による排気路５１の閉塞が防止でき、異物による排気路５１の閉塞に起因する不都合の発生が抑制され、信頼性の高い両面焼きグリル４０となっている。 By providing the dust-proof member 55, foreign matter that has fallen from between the outer periphery of the second exhaust passage 52 and the inner periphery of the exhaust passage 51 can be prevented from entering the exhaust passage 51, so that the exhaust passage 51 is blocked by the foreign matter. Thus, the occurrence of inconvenience due to the blockage of the exhaust passage 51 due to foreign matter is suppressed, and the double-sided grill 40 is highly reliable.
また、防塵部材５５は、通気孔を多数備えた多孔状体にて構成されている。具体的には、この防塵部材５５は、多数の通気孔が形成された金網であるラス網にて構成されており、各通気孔の大きさ（メッシュサイズ）は、４ｍｍ×２ｍｍの大きさに設定されている。 Moreover, the dustproof member 55 is comprised with the porous body provided with many ventilation holes. Specifically, the dust-proof member 55 is constituted by a lath net that is a metal net having a large number of air holes, and the size (mesh size) of each air hole is 4 mm × 2 mm. Is set.
このように構成することで、防塵部材５５は、万が一グリル庫３０内において被調理物３４が発火した場合にも、被調理物３４の発火によって形成された炎が第２排気路５２の外周と排気路５１の内周との間を通って排気出口４５から機外に伸びることを防止する消炎部材として兼用できるので、両面焼きグリル４０の製造コストが低減できる。 By configuring in this way, the dust-proof member 55 can prevent the flame formed by the ignition of the cooking object 34 from the outer periphery of the second exhaust path 52 even if the cooking object 34 ignites in the grill 30. Since it can also be used as a flame extinguishing member that prevents the gas from passing from the exhaust outlet 45 to the outside through the inner periphery of the exhaust passage 51, the manufacturing cost of the double-sided grill 40 can be reduced.
つまり、万が一グリル庫３０内において被調理物３４が発火した場合には、被調理物３４の発火によって形成される炎は、仕切り板５３の上側を通って排気路５１から機外に伸びようとすることになるが、第２排気路５２の外周と排気路５１の内周との間には、通気孔を多数備えた多孔状体にて構成される防塵部材５５を備えるので、被調理物３４の発火によって形成された炎が、多孔状体に多数備える通気孔を通過しようとする際に炎の温度が低下して、いわゆるクエンチング効果によって消炎することになり、消炎部材を防塵部材５５と別体に備える必要がなく、両面焼きグリル４０の製造コストが低減できる。 That is, in the unlikely event that the cooking object 34 ignites in the grill cabinet 30, the flame formed by the ignition of the cooking object 34 tends to extend from the exhaust path 51 to the outside of the machine through the upper side of the partition plate 53. However, between the outer periphery of the second exhaust passage 52 and the inner periphery of the exhaust passage 51, the dustproof member 55 formed of a porous body having a large number of air holes is provided, so that the food to be cooked When the flame formed by the ignition of 34 attempts to pass through a plurality of air holes provided in the porous body, the temperature of the flame is lowered and the flame is extinguished by a so-called quenching effect. The manufacturing cost of the double-sided grill 40 can be reduced.
また、防塵部材５５には、図示しない酸化触媒５５ａを担持させてあり、防塵部材５５が、例えば白金やパラジウム等からなる酸化触媒５５ａを担持させた多孔状体にて構成されることになり、上側調理排気３８は、消炎部材を兼ねる防塵部材５５を構成する多孔状体における多数の通気孔を通過する際に、上側調理排気３８に含まれる臭い成分や未燃成分が酸化触媒５５ａによって酸化処理されて、上側調理排気３８が浄化された状態で機器外部に排出されることになり好都合である。 The dustproof member 55 carries an oxidation catalyst 55a (not shown), and the dustproof member 55 is constituted by a porous body carrying an oxidation catalyst 55a made of, for example, platinum or palladium. When the upper cooking exhaust 38 passes through a large number of air holes in the porous body constituting the dust-proof member 55 that also serves as a flame extinguishing member, the odorous components and unburned components contained in the upper cooking exhaust 38 are oxidized by the oxidation catalyst 55a. As a result, it is convenient that the upper cooking exhaust 38 is discharged to the outside of the device in a purified state.
因みに、図３に示すように仕切り板５３のグリル庫３０側の端部の高さを焼き網３３の高さと略同じ高さとする、若しくは、仕切り板５３のグリル庫３０側の端部の高さを焼き網３３の高さより低くした場合には、被調理物３４から発生する臭い成分は主に仕切り板５３の上側を通過し、上側通流排気３８として排出されるものであるから、例えば白金やパラジウム等からなる酸化触媒５５ａを担持させた多孔状体にて構成された、消炎部材を兼ねる防塵部材５５によって被調理物３４から発生する臭い成分が効率よく浄化されることになる。 Incidentally, as shown in FIG. 3, the height of the end of the partition plate 53 on the side of the grill ware 30 is substantially the same as the height of the grill 33, or the height of the end of the partition plate 53 on the side of the grill ware 30. When the height is lower than the height of the grill 33, the odor component generated from the cooking object 34 mainly passes through the upper side of the partition plate 53 and is discharged as the upper flow exhaust 38. The odorous component generated from the object to be cooked 34 is efficiently purified by the dustproof member 55 that also serves as a flame extinguishing member, which is composed of a porous body carrying an oxidation catalyst 55a made of platinum, palladium, or the like.
