特開２０１５−１５５７７７号公報JP 2015-155777 A

上述した特許文献１に記載の加熱調理器では、洗浄ノズルは調理庫の天井壁に固定される取付ヘッドと、取付ヘッドに回転可能に遊嵌されるスリーブと、スリーブから径方向に延びる噴射管とを備え、噴射管を噴射口から噴射される洗浄水によってスリーブとともに回転させることで、洗浄水を調理庫の周壁の全体に噴射するようにしている。しかし、この種の加熱調理器では、調理庫内には食材の加熱調理の際に油が多く飛散して、飛散した油が洗浄ノズルの取付ヘッドとスリーブとの間で固化することで、スリーブが取付ヘッドに固着し、噴射管がスリーブとともに回転しなくなるおそれがある。このため、特許文献１の加熱調理器では、調理庫を洗浄するたびに洗浄ノズルを調理庫の天井壁に取り付ける必要があり、調理庫の洗浄作業が面倒である問題があった。   In the heating cooker described in Patent Document 1 described above, the cleaning nozzle has a mounting head fixed to the ceiling wall of the cooking chamber, a sleeve rotatably fitted to the mounting head, and an injection pipe extending radially from the sleeve. The cleaning pipe is rotated with the sleeve by the cleaning water injected from the injection port, so that the cleaning water is injected to the entire peripheral wall of the cooking cabinet. However, in this type of heating cooker, a large amount of oil is scattered in the cooking chamber when cooking food, and the scattered oil is solidified between the mounting head of the washing nozzle and the sleeve. May stick to the mounting head and the injection tube may not rotate with the sleeve. For this reason, in the heating cooker of patent document 1, it was necessary to attach a washing nozzle to the ceiling wall of the cooking cabinet every time the cooking cabinet was washed, and there was a problem that cleaning work of the cooking cabinet was troublesome.

また、この特許出願人は、この出願より前に提出の特願２０１８−０２３０２８にて、上下に洗浄水を通す洗浄水通路を有した金属製の円筒部材よりなる洗浄水ノズルを開発している。円筒形をした洗浄水ノズルの周面にはスリットよりなる洗浄水の噴射口が形成されており、洗浄水通路から供給される洗浄水はスリットよりなる噴射口から噴射される。また、スリットよりなる噴射口は斜め上方に向けて開口しており、スリットよりなる噴射口から噴射される洗浄水は調理庫の天井壁に向けて噴射される。   Further, the applicant of the present patent has developed a washing water nozzle formed of a metal cylindrical member having a washing water passage for vertically passing washing water in Japanese Patent Application No. 2018-023028 filed before this application. . A cleaning water injection port formed of a slit is formed on the peripheral surface of the cylindrical cleaning water nozzle, and the cleaning water supplied from the cleaning water passage is injected from the injection port formed of the slit. In addition, the outlet formed by the slit is opened obliquely upward, and the washing water sprayed from the outlet formed by the slit is sprayed toward the ceiling wall of the cooking cabinet.

この洗浄ノズルの噴射口には調理庫内で加熱調理をしたときの油分等が付着し、付着した油分等は高温の調理庫内で噴射口に強固に固着するため、洗浄ノズルの噴射口に強固に固着した油分を洗浄するのが困難であった。また、スリットよりなる噴射口は円筒形の洗浄ノズルの軸方向に斜めに傾斜して形成されており、円筒形の洗浄ノズルにスリットを斜めに形成するのは技術的に面倒であった。本発明は、調理庫の洗浄作業が面倒とならない加熱調理器を提供し、さらに、洗浄ノズルの加工を容易にするとともに洗浄の作業性を高めるようにすることを目的とする。   The oil and the like when heating and cooking in the cooking chamber adhere to the injection port of the washing nozzle, and the attached oil and the like are firmly fixed to the injection port in the high-temperature cooking chamber. It was difficult to wash the firmly fixed oil. Further, the injection port formed of the slit is formed obliquely inclined in the axial direction of the cylindrical cleaning nozzle, and it is technically troublesome to form the slit obliquely in the cylindrical cleaning nozzle. SUMMARY OF THE INVENTION It is an object of the present invention to provide a heating cooker in which a cleaning operation of a cooking cabinet is not troublesome, and to further facilitate a processing of a cleaning nozzle and enhance a cleaning workability.

上記課題を解決するために、本発明は、食材を加熱調理するための調理庫と、調理庫内の一方の側部に配置されて、調理庫内を加熱するヒータと、調理庫内の一方の側部に配置されて、調理庫内の空気を対流させる対流ファンと、調理庫の一方の側部と他の部分とを通風可能に仕切るファンカバーとを備え、対流ファンによって調理庫内の他方の側部から一方の側部に空気を吸い込んだ空気を調理庫の周壁に沿って一方の側部から他方の側部に送出して調理庫内の空気を循環させ、循環させた空気をヒータによって加熱した熱風によって食材を加熱調理する加熱調理器であって、調理庫の天井壁には上下に延びる洗浄水通路を有する筒形をした洗浄ノズルを設け、洗浄ノズルは第１構成部と、第１構成部の下側に配置される第２構成部とを上下に分割可能に有し、第１構成部の下面と第２構成部の上面との間に形成される第１隙間部によって洗浄水通路と連通した第１噴射口を形成したことを特徴とする加熱調理器を提供するものである。   In order to solve the above problems, the present invention provides a cooking cabinet for heating and cooking ingredients, a heater disposed on one side of the cooking cabinet to heat the cooking cabinet, and one of the cooking cabinets. A convection fan that is arranged on the side of the cooking cabinet and convects the air in the cooking cabinet, and a fan cover that divides one side of the cooking cabinet and the other part so as to allow air to flow therethrough, and the convection fan controls the inside of the cooking cabinet. The air sucked into the one side from the other side is sent out from one side to the other side along the peripheral wall of the cooking cabinet to circulate the air in the cooking cabinet, and the circulated air is discharged. A cooking device for heating and cooking foods by hot air heated by a heater, wherein a cylindrical cleaning nozzle having a vertically extending cleaning water passage is provided on a ceiling wall of a cooking cabinet, and the cleaning nozzle includes a first component and a cleaning nozzle. And the second component disposed below the first component. And a first injection port communicating with the washing water passage is formed by a first gap formed between a lower surface of the first component and an upper surface of the second component. A heating cooker is provided.

上記のように構成した加熱調理器においては、調理庫の天井壁には上下に延びる洗浄水通路を有する筒形をした洗浄ノズルを設け、洗浄ノズルは第１構成部と、第１構成部の下側に配置される第２構成部とを上下に分割可能に有し、第１構成部の下面と第２構成部の上面との間に形成される第１隙間部によって洗浄水通路と連通した第１噴射口を形成させた。洗浄ノズルは回転等する可動部品を備えたものでないので、調理庫内で加熱調理をしているときに洗浄ノズルを調理庫の天井壁に取り付けた状態としても、洗浄ノズルが油汚れで固着して動かなくなるような不具合を生じないようにすることができた。また、第１構成部の下面と第２構成部の上面との間に形成される第１隙間部によって洗浄水通路と連通した第１噴射口を形成させたので、第２構成部を第１構成部から分解することで第１噴射口に固着した汚れを容易に洗浄することができるようになった。   In the heating cooker configured as described above, a cylindrical cleaning nozzle having a vertically extending cleaning water passage is provided on the ceiling wall of the cooking chamber, and the cleaning nozzle includes a first component and a first component. A second component disposed on the lower side is vertically splittable and communicates with the washing water passage by a first gap formed between a lower surface of the first component and an upper surface of the second component. The formed first injection port was formed. The washing nozzle does not have any moving parts that rotate, so even if the washing nozzle is attached to the ceiling wall of the cooking cabinet during heating cooking in the cooking cabinet, the cleaning nozzle adheres with oil stains. It was possible to prevent a malfunction that would not work. In addition, the first gap that is formed between the lower surface of the first component and the upper surface of the second component forms the first injection port that is in communication with the washing water passage. By disassembling from the constituent part, the dirt fixed on the first injection port can be easily washed.

上記のように構成した加熱調理器においては、洗浄水通路内には第２構成部の上面に当接して第１隙間部の間隔を保持するスペーサを設けるのが好ましい。このようにしたときには、第１構成部と第２構成部との間に形成される第１隙間部の間隔を適切に保持できるようになった。また、この場合において、スペーサは第１構成部に固定されて内側に雌ねじ部を有する筒形状をし、第２構成部は下側から挿通される取付ねじをスペーサの雌ねじ部に螺着させることによって第１構成部に着脱可能に取り付けられのが好ましい。また、第２構成部の下面には取付ねじの頭部を収納する凹部を形成するのが好ましく、このようにしたときには、洗浄ノズルの第２構成部の下面には調理庫内で加熱調理したときの油分等による汚れが付着するが、取付ねじの頭部は第２構成部の下面に形成された凹部に収納されているので、取付ねじの頭部と第２構成部の下面の凹部との接触部分に油分等による汚れが付着しにくくなり、取付ねじの頭部が第２構成部の下面に固着しにくくなった。   In the heating cooker configured as described above, it is preferable to provide a spacer in the washing water passage that abuts on the upper surface of the second component to maintain the interval between the first gaps. In this case, the interval of the first gap formed between the first component and the second component can be appropriately maintained. In this case, the spacer is fixed to the first component and has a cylindrical shape having a female screw portion on the inside, and the second component is configured to screw a mounting screw inserted from below into the female screw portion of the spacer. Is preferably detachably attached to the first component. In addition, it is preferable to form a recess for accommodating the head of the mounting screw on the lower surface of the second component, and in such a case, the lower surface of the second component of the cleaning nozzle is heated and cooked in a cooking chamber. Although the dirt due to oil and the like adheres, the head of the mounting screw is housed in the concave portion formed on the lower surface of the second component, so that the head of the mounting screw and the concave portion on the lower surface of the second component are The dirt due to oil or the like hardly adheres to the contact portion of the second member, and the head of the mounting screw does not easily adhere to the lower surface of the second component.

上記のように構成した加熱調理器の他の実施形態においては、第２構成部は第１構成部に上側から挿通される第１固定ねじを用いて着脱可能に固定され、第１固定ねじの長さを調理庫の天井壁と第１構成部の上面との間隔よりも長くするのが好ましい。このようにしたときには、第１固定ねじが弛んでも、第１固定ねじは調理庫の天井壁に当たることで上側への移動が規制され、第１固定ねじと第２構成部が調理庫に落下するのを防ぐことができ、第１固定ねじと第２構成部が調理庫内で調理中の食材に混入するのを防ぐことができた。   In another embodiment of the heating cooker configured as described above, the second component is detachably fixed to the first component using a first fixing screw inserted from above, and Preferably, the length is longer than the distance between the ceiling wall of the cooking cabinet and the upper surface of the first component. In this case, even if the first fixing screw is loosened, the upward movement of the first fixing screw is restricted by hitting the ceiling wall of the cooking cabinet, and the first fixing screw and the second component fall into the cooking cabinet. And the first fixing screw and the second component can be prevented from being mixed into the food being cooked in the cooking chamber.

上記のように構成した加熱調理器においては、洗浄ノズルは第２構成部の下側から挿通される取付ねじによって調理庫の天井壁に着脱可能に取り付けられており、第２構成部の下面には取付ねじの頭部を収納する凹部を形成するのが好ましい。洗浄ノズルの第２構成部の下面には調理庫内で加熱調理したときの油分等による汚れが付着するが、取付ねじの頭部は第２構成部の下面に形成された凹部に収納されているので、取付ねじの頭部と第２構成部の下面の凹部との接触部分に油分等による汚れが付着しにくくなり、取付ねじの頭部が第２構成部の下面に固着しにくくなった。   In the heating cooker configured as described above, the washing nozzle is detachably attached to the ceiling wall of the cooking cabinet by a mounting screw inserted from below the second component, and is attached to the lower surface of the second component. Preferably form a recess for accommodating the head of the mounting screw. Dirt due to oil and the like when heating and cooking in the cooking chamber adheres to the lower surface of the second component of the cleaning nozzle, but the head of the mounting screw is housed in a recess formed on the lower surface of the second component. As a result, dirt due to oil and the like hardly adheres to a contact portion between the head of the mounting screw and the recess on the lower surface of the second component, and the head of the mounting screw does not easily adhere to the lower surface of the second component. .

上記のように構成した加熱調理器においては、洗浄ノズルは第２構成部の下側に配置される第３構成部を分割可能にさらに備え、第２構成部の下面と第３構成部の上面との間に形成される第２隙間部によって第１噴射口が形成された位置と洗浄水通路を挟んだ反対側に洗浄水通路と連通した第２噴射口を形成するのが好ましい。このようにしたときには、調理庫内を広い範囲で洗浄することができるようになった。また、第２構成部の下面と第３構成部の上面との間に形成される第２隙間部によって洗浄水通路と連通した第２噴射口を形成させたので、第３構成部を第２構成部から分解することで第２噴射口に固着した汚れを容易に洗浄することができるようになった。   In the heating cooker configured as described above, the washing nozzle further includes a third component disposed below the second component so as to be dividable, and a lower surface of the second component and an upper surface of the third component. It is preferable to form a second injection port communicating with the washing water passage on the opposite side of the position where the first injection port is formed by the second gap formed between the cleaning water passage and the washing water passage. In such a case, the inside of the cooking cabinet can be cleaned in a wide range. In addition, the second gap formed between the lower surface of the second component and the upper surface of the third component forms a second injection port that communicates with the washing water passage. By disassembling from the constituent part, the dirt fixed to the second injection port can be easily cleaned.

上記のように構成した加熱調理器においては、第３構成部は第１隙間部が形成されている位置で第２構成部に上側から挿通される第２固定ねじを用いて着脱可能に固定され、第２固定ねじの長さを第１隙間部の間隔よりも長くするのが好ましい。このようにしたときには、第２固定ねじが弛んでも、第２固定ねじは第１構成部の下面に当たることで上側への移動が規制され、第２固定ねじと第３構成部が調理庫に落下するのを防ぐことができ、第２固定ねじと第３構成部が調理庫内で調理中の食材に混入するのを防ぐことができた。   In the cooking device configured as described above, the third component is detachably fixed to the second component at the position where the first gap is formed by using the second fixing screw inserted from above. Preferably, the length of the second fixing screw is longer than the interval of the first gap. In this case, even if the second fixing screw is loosened, the upward movement of the second fixing screw is restricted by hitting the lower surface of the first component, and the second fixing screw and the third component drop into the cooking cabinet. It was possible to prevent the second fixing screw and the third component from being mixed into the food being cooked in the cooking chamber.

上記のように構成した加熱調理器においては、洗浄ノズルは第３構成部の下側から挿通される取付ねじによって調理庫の天井壁に着脱可能に取り付けられており、第３構成部の下面には取付ねじの頭部を収納する凹部を形成するのが好ましい。このようにしたときには、洗浄ノズルの第３構成部の下面には調理庫内で加熱調理したときの油分等による汚れが付着するが、取付ねじの頭部は第３構成部の下面に形成された凹部に収納されているので、取付ねじの頭部と第３構成部の下面の凹部との接触部分に油分等による汚れが付着しにくくなり、取付ねじの頭部が第３構成部の下面に固着しにくくなった。この場合において、取付ねじは第１隙間部または第２隙間部を通る位置に配置され、取付ねじが貫通する第１隙間部または第２隙間部には間隔を保持する間隔保持突部を設けるのが好ましい。このようにしたときには、取付ねじを強く締結しても、取付ねじが貫通する位置の第１隙間部または第２隙間部は間隔保持突部によって間隔が保持され、第１噴射口または第２噴射口の開口部分が狭くなるのを防ぐことができた。   In the heating cooker configured as described above, the washing nozzle is detachably attached to the ceiling wall of the cooking chamber by a mounting screw inserted from below the third component, and is attached to the lower surface of the third component. Preferably form a recess for accommodating the head of the mounting screw. In this case, dirt due to oil and the like when heating and cooking in the cooking chamber adheres to the lower surface of the third component of the washing nozzle, but the head of the mounting screw is formed on the lower surface of the third component. The mounting screw is housed in the concave portion, so that dirt due to oil or the like does not easily adhere to a contact portion between the head portion of the mounting screw and the concave portion on the lower surface of the third component portion, and the head portion of the mounting screw becomes It became difficult to stick to. In this case, the mounting screw is disposed at a position passing through the first clearance or the second clearance, and the first clearance or the second clearance through which the mounting screw penetrates is provided with a spacing holding protrusion for maintaining a spacing. Is preferred. In this case, even if the mounting screw is strongly fastened, the first gap portion or the second gap portion at the position where the mounting screw penetrates is maintained at an interval by the interval maintaining projection, and the first injection port or the second injection port is formed. The opening portion of the mouth was prevented from becoming narrow.

上記のように構成した加熱調理器においては、第１噴射口と第２噴射口の一方を調理庫内の一方の側部に向けて開口させ、第１噴射口と第２噴射口の他方を調理庫内の他方の側部に向けて開口させるのが好ましい。また、調理庫内の一方の側部に向けて開口させた第１噴射口と第２噴射口の一方を斜め下方に開口させ、調理庫内の他方の側部に向けて開口させた第１噴射口と第２噴射口の他方を斜め上方に開口させるのが好ましい。第１噴射口と第２噴射口の一方から調理庫内の一方の側部に向けて斜め下方に噴射された洗浄水は対流ファンによって吸い込まれて調理庫の一方の側部から他方の側部に向けて飛散し、第１噴射口と第２噴射口の他方から調理庫内の他方の側部に向けて斜め上方に噴射された洗浄水は調理庫の汚れの付着しやすい天井壁に噴き付けられてから調理庫内を対流する空気によって側壁に飛散するようになり、調理庫内の全体に洗浄水を飛散させて調理庫の全体を洗浄することができるようになった。   In the cooking device configured as described above, one of the first injection port and the second injection port is opened toward one side in the cooking chamber, and the other of the first injection port and the second injection port is connected to the other side. It is preferable to open to the other side in the cooking cabinet. In addition, one of the first injection port and the second injection port opened toward one side in the cooking chamber is opened obliquely downward, and the first injection port is opened toward the other side in the cooking chamber. It is preferable to open the other of the injection port and the second injection port diagonally upward. Wash water sprayed obliquely downward from one of the first injection port and the second injection port toward one side in the cooking chamber is sucked by the convection fan and from one side to the other side of the cooking chamber. The washing water which is scattered toward the cooking chamber and is sprayed obliquely upward from the other of the first injection port and the second injection port toward the other side of the cooking chamber is sprayed on the ceiling wall of the cooking chamber where dirt is likely to adhere. After being attached, the air is scattered on the side wall by air convection inside the cooking cabinet, and the washing water can be scattered all over the cooking cabinet to clean the entire cooking cabinet.

In addition, the cleaning program executes a single cleaning mode in which cleaning water containing detergent is circulated while being jetted, and a three-time (multiple) rinsing mode in which cleaning water containing no detergent is circulated while being jetted. Things.

調理プログラムの例えばコンビモード調理プログラムを実行したときには、ヒータ２５と対流ファン２６との作動により、調理庫２０内の空気は熱風になって循環するとともに、蒸気発生装置３０から調理庫２０内に蒸気が供給されることで、調理庫２０内に収容した食材は蒸気を含んだ熱風によって加熱調理される。このとき、食材に含まれる油分が対流する熱風とともに調理庫２０内を飛散し、油分が調理庫２０の各壁、ファンカバー２３及び支持フレーム２４等に付着することになる。この種の加熱調理器１０では調理庫２０内を常に衛生的に管理することが望ましいので、調理庫２０を例えば使用した日毎に洗浄することが好ましい。このために、この加熱調理器１０では調理庫２０内を自動で洗浄する洗浄プログラムを有している。   When a cooking program, for example, a combination mode cooking program, is executed, the air in the cooking cabinet 20 is circulated as hot air by the operation of the heater 25 and the convection fan 26, and the steam from the steam generator 30 into the cooking cabinet 20. Is supplied, the ingredients stored in the cooking cabinet 20 are cooked by hot air containing steam. At this time, the oil contained in the foodstuffs scatters in the cooking cabinet 20 together with the convection hot air, and the oil adheres to each wall of the cooking cabinet 20, the fan cover 23, the support frame 24 and the like. In this type of heating cooker 10, since it is desirable to always maintain the cooking cabinet 20 in a sanitary manner, it is preferable to clean the cooking cabinet 20 every day that it is used. For this purpose, the heating cooker 10 has a cleaning program for automatically cleaning the inside of the cooking cabinet 20.

調理庫２０内を洗浄するときには、調理庫２０の排水口２０ｃに設けたに排水目皿２０ｄの上側にタブレット形の洗剤を置いた状態で洗浄プログラムを実行させる。洗浄プログラムは、洗剤を含んだ洗浄水で洗浄する洗浄モードと、洗剤を含まない洗浄水で濯ぎ洗浄をする３回の濯ぎモードを実行する。なお、洗浄モードを実行する前に、蒸気発生装置３０を作動させて調理庫２０内に蒸気を供給するようにして、調理庫２０の周壁に付着している油分等の汚れを浮かせるようにするのが好ましい。   When the inside of the cooking cabinet 20 is cleaned, the cleaning program is executed in a state where a tablet-shaped detergent is placed above the drainage dish 20d provided in the drain port 20c of the cooking cabinet 20. The washing program executes a washing mode of washing with washing water containing a detergent and a three-time rinsing mode of rinsing with washing water containing no detergent. Before executing the cleaning mode, the steam generator 30 is operated to supply steam into the cooking cabinet 20 so that dirt such as oil adhering to the peripheral wall of the cooking cabinet 20 is floated. Is preferred.

洗浄モードを開始すると、排水弁１７を閉止するとともに給水弁５４を所定時間開放することで、排水タンク１４内に洗浄水が貯えられるようになる。排水タンク１４内に洗浄水が貯まった後でポンプ５２を作動させると、排水タンク１４内に貯えられた洗浄水は洗浄水供給管５０を通って洗浄ノズル４０に送られる。洗浄水は洗浄ノズル４０の洗浄水通路４１ａ，４２ａを通って第１及び第２噴射口４０ｂ，４０ｄから噴射される。また、ポンプ５２を作動させているときに、ヒータ２５と対流ファン２６とを作動させているために、洗浄ノズル４０の第１及び第２噴射口４０ｂ，４０ｄから噴き出された洗浄水は調理庫２０内を対流する温風によって温められながら調理庫２０を広範囲に飛散している。また、洗浄ノズル４０の第１及び第２噴射口４０ｂ，４０ｄから噴き出された洗浄水は調理庫２０内の天井壁や各側壁等に沿って流れ落ちる。このとき、排水タンク１４と調理庫２０内を循環する洗浄水は排水口２０ｃを通るときに排水目皿２０ｄの上側に置いた洗剤が溶けるようになっており、調理庫２０は洗剤を含む洗浄水により洗浄される。   When the cleaning mode is started, the drainage valve 17 is closed and the water supply valve 54 is opened for a predetermined time, so that the cleaning water is stored in the drainage tank 14. When the pump 52 is operated after the washing water has been stored in the drain tank 14, the washing water stored in the drain tank 14 is sent to the washing nozzle 40 through the washing water supply pipe 50. The cleaning water is injected from the first and second injection ports 40b and 40d through the cleaning water passages 41a and 42a of the cleaning nozzle 40. Further, since the heater 25 and the convection fan 26 are operated when the pump 52 is operated, the cleaning water spouted from the first and second injection ports 40b and 40d of the cleaning nozzle 40 is used for cooking. The cooking cabinet 20 is scattered over a wide area while being heated by the convection warm air inside the cooking cabinet 20. Further, the cleaning water spouted from the first and second injection ports 40b and 40d of the cleaning nozzle 40 flows down along the ceiling wall, the side walls, and the like in the cooking cabinet 20. At this time, the washing water circulating in the drainage tank 14 and the cooking cabinet 20 is configured such that the detergent placed above the drainage dish 20d is dissolved when passing through the drainage port 20c, and the cooking cabinet 20 contains the detergent containing the detergent. Washed with water.

洗浄ノズル４０の各噴射口４０ｂ，４０ｄから噴射された洗浄水の流れについて詳述する。洗浄ノズル４０の第１噴射口４０ｂから噴き出された洗浄水は調理庫２０の天井壁及び右側部（他方の側部）に向けて前後方向に広範囲に拡がって噴き付けられる。第１噴射口４０ｂから噴き出された洗浄水は調理庫２０内を対流する温風によって食材収容室２１内で広範囲に飛散し、洗浄水の一部は調理庫２０の側壁に沿って流れ落ち、流れ落ちた洗浄水は再び排水タンク１４から洗浄ノズル４０に送られて排水タンク１４と調理庫２０内を循環するとともに、洗浄水の一部はファンカバー２３の吸込口２３ａから熱風生成室２２側に吸い込まれ、対流ファン２６によって再び食材収容室２１側に飛散する。   The flow of the cleaning water injected from each of the injection ports 40b and 40d of the cleaning nozzle 40 will be described in detail. The cleaning water spouted from the first injection port 40b of the cleaning nozzle 40 is widely sprayed toward the ceiling wall and the right side (the other side) of the cooking cabinet 20 in the front-rear direction. The cleaning water spouted from the first injection port 40b is scattered widely in the food storage chamber 21 by the warm air convection in the cooking chamber 20, and a part of the cleaning water flows down along the side wall of the cooking chamber 20, The washing water that has flowed down is sent again from the drain tank 14 to the washing nozzle 40 and circulates through the drain tank 14 and the cooking chamber 20, and a part of the washing water flows from the suction port 23 a of the fan cover 23 to the hot air generation chamber 22 side. It is sucked and scattered again by the convection fan 26 to the foodstuff storage room 21 side.

洗浄ノズル４０の第２噴射口４０ｄから噴き出された洗浄水は調理庫２０の左側部にて食材収容室２１と熱風生成室２２とを仕切るファンカバー２３に向けて噴き出される。噴き出された洗浄水はファンカバー２３を流れ落ちるとともにファンカバー２３の吸込口２３ａから熱風生成室２２側に吸い込まれ、対流ファン２６によって食材収容室２１側に飛散する。洗浄水の一部は調理庫２０の側壁に沿って流れ落ち、洗浄水の一部はファンカバー２３の吸込口２３ａから熱風生成室２２側に吸い込まれ、対流ファン２６によって再び食材収容室２１側に飛散する。調理庫２０の側壁に沿って流れ落ちた洗浄水は再び排水タンク１４から洗浄ノズル４０に送られ、排水タンク１４と調理庫２０内とを循環する。このように、各噴射口４０ｂ，４０ｄから噴き出された洗浄水は排水タンク１４と調理庫２０内を循環しながら調理庫２０内の隅々まで噴き付けられるようになっている。なお、対流ファン２６を正方向と逆方向で交互に回転させるようにして、調理庫２０内を対流する空気の流れを変えるようにすれば、洗浄ノズル４０の各噴射口４０ｂ，４０ｄから噴き出された洗浄水は対流ファン２６の正方向で回転させたときと逆方向で回転させたときで変わる空気の流れにより調理庫２０内のさらに隅々まで噴き付けられるようになる。洗浄プログラムの洗浄モードを所定時間実行すると、ヒータ２５と対流ファン２６とポンプ５２の作動を停止させ、排水弁１７を開放して排水タンク１４内の洗剤を含んだ洗浄水を排水する。   The washing water spouted from the second jetting port 40d of the washing nozzle 40 is spouted toward the fan cover 23 separating the food storage chamber 21 and the hot air generation chamber 22 on the left side of the cooking cabinet 20. The jetted washing water flows down the fan cover 23 and is sucked into the hot air generation chamber 22 through the suction port 23 a of the fan cover 23, and scatters to the food storage chamber 21 by the convection fan 26. A part of the washing water flows down along the side wall of the cooking cabinet 20, and a part of the washing water is sucked into the hot air generation chamber 22 from the suction port 23a of the fan cover 23, and is again returned to the food storage chamber 21 by the convection fan 26. Scatter. The washing water that has flowed down along the side wall of the cooking cabinet 20 is sent from the drain tank 14 to the washing nozzle 40 again, and circulates between the drain tank 14 and the cooking cabinet 20. In this way, the washing water spouted from each of the injection ports 40b and 40d is sprayed to every corner in the cooking cabinet 20 while circulating in the drainage tank 14 and the cooking cabinet 20. If the convection fan 26 is alternately rotated in the normal direction and the reverse direction to change the flow of air convection in the cooking chamber 20, the jets 40b and 40d of the washing nozzle 40 are ejected. The washing water thus sprayed is sprayed to every corner in the cooking cabinet 20 by the flow of air that changes when the convection fan 26 is rotated in the normal direction and when it is rotated in the opposite direction. When the cleaning mode of the cleaning program is executed for a predetermined time, the operations of the heater 25, the convection fan 26, and the pump 52 are stopped, the drain valve 17 is opened, and the cleaning water containing the detergent in the drain tank 14 is drained.

洗浄プログラムの洗浄モードが終了すると、濯ぎモードを実行する。濯ぎモードでは、排水弁１７を閉止するとともに給水弁５４を所定時間開放することで、排水タンク１４内に濯ぎ用の洗浄水を貯えるようにする。その後、ポンプ５２を作動させると、排水タンク１４内に貯えられた洗浄水は洗浄水供給管５０を通って洗浄ノズル４０に送られ、上述した洗浄モードと同様に、洗浄ノズル４０の各噴射口４０ｂ，４０ｄから噴き出される洗浄水は調理庫２０の周壁、ファンカバー２３及び支持フレーム２４の隅々まで噴き付けられるようになり、洗浄モードに噴き付けられた洗剤を含んだ洗浄水を洗い流すようにすることができる。この濯ぎモードでも、ヒータ２５と対流ファン２６を作動させるとともに、対流ファン２６を正方向と逆方向とで交互に回転させるようにしている。洗浄プログラムの濯ぎモードを所定時間実行すると、ヒータ２５と対流ファン２６とポンプ５２の作動を停止させ、排水弁１７を開放して排水タンク１４内の濯ぎに用いた洗浄水を排水する。なお、この実施形態では濯ぎモードを複数回として３回実行して洗浄プログラムを終了する。   When the cleaning mode of the cleaning program ends, the rinsing mode is executed. In the rinsing mode, the drain valve 17 is closed and the water supply valve 54 is opened for a predetermined time so that the rinsing water is stored in the drain tank 14. Thereafter, when the pump 52 is operated, the washing water stored in the drainage tank 14 is sent to the washing nozzle 40 through the washing water supply pipe 50, and, similarly to the above-described washing mode, each injection port of the washing nozzle 40 The washing water spouted from 40b and 40d is sprayed to the peripheral wall of the cooking cabinet 20, the fan cover 23 and the corners of the support frame 24, so that the washing water containing the detergent spouted in the washing mode is washed away. Can be Also in this rinsing mode, the heater 25 and the convection fan 26 are operated, and the convection fan 26 is alternately rotated in the normal direction and the reverse direction. When the rinsing mode of the cleaning program is executed for a predetermined time, the operations of the heater 25, the convection fan 26, and the pump 52 are stopped, the drain valve 17 is opened, and the cleaning water used for rinsing in the drain tank 14 is drained. In this embodiment, the rinsing mode is executed a plurality of times, and is executed three times to end the cleaning program.

上記のように構成した加熱調理器１０においては、調理庫２０の天井壁には上下に延びる洗浄水通路４１ａ，４２ａを有する筒形をした洗浄ノズル４０を設け、洗浄ノズル４０は第１構成部４１と、第１構成部４１の下側に配置される第２構成部４２と、第２構成部４２の下側に配置される第３構成部４３とを上下に分割可能に有し、第１構成部４１の下面と第２構成部４２の上面との間に形成される第１隙間部４０ａによって洗浄水通路４１ａと連通した第１噴射口４０ｂを形成させ、第２構成部４２の下面と第３構成部４３の上面との間に形成される第２隙間部４０ｃによって洗浄水通路４１ａ，４２ａと連通した第２噴射口４０ｄを形成させた。   In the cooking device 10 configured as described above, a cylindrical cleaning nozzle 40 having cleaning water passages 41a and 42a extending vertically is provided on the ceiling wall of the cooking cabinet 20, and the cleaning nozzle 40 is a first component. 41, a second component 42 disposed below the first component 41, and a third component 43 disposed below the second component 42 are vertically splittable. A first gap 40a formed between the lower surface of the first component 41 and the upper surface of the second component 42 forms a first injection port 40b communicating with the washing water passage 41a, and the lower surface of the second component 42 A second gap 40c formed between the first and second components 43 forms a second injection port 40d communicating with the washing water passages 41a and 42a.

この洗浄ノズル４０は回転等する可動部品を備えたものでないので、調理庫２０内で加熱調理をしているときに、洗浄ノズル４０を調理庫２０の天井壁に取り付けた状態としても、洗浄ノズル４０が油汚れで固着して動かなくなるような不具合が生じないようにすることができた。また、洗浄ノズル４０は、第１構成部４１の下面と第２構成部４２の上面との間に形成される第１隙間部４０ａによって洗浄水通路４１ａと連通した第１噴射口４０ｂを形成させ、第２構成部４２の下面と第３構成部４３の上面との間に形成される第２隙間部４０ｃによって洗浄水通路４１ａ，４２ａと連通した第２噴射口４０ｄを形成させたので、第３構成部４３を第２構成部４２から分離させる（分解する）とともに、第２構成部４２を第１構成部４１から分離させる（分解する）ことで第１及び第２噴射口４０ｂ，４０ｄに固着した汚れを容易に洗浄することができるようになった。   Since the cleaning nozzle 40 does not include a movable part that rotates, the cleaning nozzle 40 may be attached to the ceiling wall of the cooking chamber 20 during heating cooking in the cooking chamber 20. It was possible to prevent such a problem that the 40 could not move due to sticking with oil stains. Further, the cleaning nozzle 40 forms a first injection port 40b communicating with the cleaning water passage 41a by a first gap 40a formed between the lower surface of the first component 41 and the upper surface of the second component 42. Since the second gap 40c formed between the lower surface of the second component 42 and the upper surface of the third component 43 forms the second injection port 40d communicating with the washing water passages 41a and 42a, By separating (disassembling) the three constituent parts 43 from the second constituent part 42 and separating (disassembling) the second constituent part 42 from the first constituent part 41, the first and second injection ports 40b and 40d are separated. The fixed dirt can be easily cleaned.

この実施形態の洗浄ノズル４０では、第１構成部４１の下面を下側に膨らむ円錐台面４１ｂとするとともに、第２構成部４２の上面に互いに上下位置を異なるように形成した下側に凹む円錐台の周面の一部よりなる第１周面部４２ｂと第２周面部４２ｃとを形成し、第１構成部４１の下面と第２構成部４２の上面との間に第１隙間部４０ａを形成した。本発明は、これに限られるものでなく、第１構成部４１の下面に互いに上下位置を異なるように形成した下側に膨らむ円錐台の周面の一部よりなる第１周面部と第２周面部を形成するとともに、第２構成部４２の上面を下側に凹む円錐台面とし、第１構成部４１の下面と第２構成部４２の上面との間に第１隙間部を形成したものであってもよい。同様に、第２構成部４２の下面に互いに上下位置を異なるように形成した円錐台の周面の一部よりなる第３周面部４２ｄと第４周面部４２ｅとを形成するとともに、第３構成部４３の上面を上側に膨らむ円錐台面４３ａとし、第２構成部４２の下面と第３構成部４３の上面との間に第２隙間部４０ｃを形成した。本発明は、これに限られるものでなく、第２構成部４２の下面を上側に凹む円錐台面とするとともに、第３構成部４３の上面に互いに上下位置を異なるように形成した円錐台の周面の一部よりなる第３周面部と第４周面部を形成し、第２構成部４２の下面と第３構成部４３の上面との間に第２隙間部を形成したものであってもよい。さらに、第１及び第２構成部４１，４２の間に形成される第１噴射口４０ｂを調理庫２０の左側部（一方の側部）にて斜め下方に向けて開口させ、第２及び第３構成部４２，４３の間に形成される第２噴射口４０ｄを調理庫２０の右側部（他方の側部）にて斜め上方に向けて開口させてもよい。   In the cleaning nozzle 40 of this embodiment, the lower surface of the first component 41 is a frustoconical surface 41b that swells downward, and the lower concave cone that is formed on the upper surface of the second component 42 so as to have a different vertical position. A first peripheral surface portion 42b and a second peripheral surface portion 42c, which are part of the peripheral surface of the table, are formed, and a first gap portion 40a is formed between the lower surface of the first component 41 and the upper surface of the second component 42. Formed. The present invention is not limited to this, and the first peripheral surface portion and the second peripheral surface portion which are formed on the lower surface of the first component portion 41 so as to have different vertical positions from each other and which are part of the peripheral surface of the truncated conical cone extending downward. Forming a peripheral surface, forming the upper surface of the second component 42 as a truncated conical surface concave downward, and forming a first gap between the lower surface of the first component 41 and the upper surface of the second component 42. It may be. Similarly, a third peripheral surface portion 42d and a fourth peripheral surface portion 42e, each of which is a part of a peripheral surface of a truncated cone formed so as to be vertically different from each other, are formed on a lower surface of the second component portion 42, and a third configuration is provided. The upper surface of the portion 43 is a frustoconical surface 43a bulging upward, and a second gap portion 40c is formed between the lower surface of the second component 42 and the upper surface of the third component 43. The present invention is not limited to this, and the lower surface of the second component 42 is a frustoconical surface recessed upward, and the periphery of the frustoconical cone formed on the upper surface of the third component 43 so as to be vertically different from each other. A third peripheral surface portion and a fourth peripheral surface portion that are part of the surface are formed, and a second gap is formed between the lower surface of the second component 42 and the upper surface of the third component 43. Good. Further, the first injection port 40b formed between the first and second components 41 and 42 is opened obliquely downward at the left side (one side) of the cooking cabinet 20, and the second and the second ports are opened. The second injection port 40d formed between the three components 42 and 43 may be opened obliquely upward at the right side (the other side) of the cooking cabinet 20.

また、加熱調理器１０の洗浄ノズル４０においては、第２構成部４２は第１構成部４１に上側から挿通される第１固定ねじ４４を用いて着脱可能に固定され、第１固定ねじ４４の長さを調理庫２０の天井壁と第１構成部４１の上面との間隔よりも長くした。このため、第１固定ねじ４４が第２構成部４２の雌ねじ部で弛んでも、第１固定ねじ４４は調理庫２０の天井壁に当たることで上側への移動が規制され、第１固定ねじ４４と第３構成部４３を含めた第２構成部４２が調理庫２０内に落下するのを防ぐことができ、第１固定ねじ４４と第３構成部４３を含めた第２構成部４２が調理庫２０内で調理中の食材に混入するのを防ぐことができた。同様に、第３構成部４３は第１隙間部４０ａが形成されている位置で第２構成部４２に上側から挿通される第２固定ねじ４５を用いて着脱可能に固定され、第２固定ねじ４５の長さを第１隙間部４０ａの間隔よりも長くした。このため、第２固定ねじ４５が第３構成部４３の雌ねじ部で弛んでも、第２固定ねじ４５は第１構成部４１の下面に当たることで上側への移動が規制され、第２固定ねじ４５と第３構成部４３が調理庫２０に落下するのを防ぐことができ、第２固定ねじ４５と第３構成部４３が調理庫２０内で調理中の食材に混入するのを防ぐことができた。   In the cleaning nozzle 40 of the heating cooker 10, the second component 42 is detachably fixed to the first component 41 using a first fixing screw 44 inserted from above, and the first fixing screw 44 The length was longer than the distance between the ceiling wall of the cooking cabinet 20 and the upper surface of the first component 41. For this reason, even if the first fixing screw 44 is loosened by the female screw portion of the second component 42, the first fixing screw 44 is restricted from moving upward by hitting the ceiling wall of the cooking cabinet 20, and the first fixing screw 44 The second component 42 including the third component 43 can be prevented from dropping into the cooking cabinet 20, and the second component 42 including the first fixing screw 44 and the third component 43 can be used as the cooking cabinet. 20 was able to be prevented from being mixed into the ingredients being cooked. Similarly, the third component 43 is detachably fixed to the second component 42 at the position where the first gap portion 40a is formed by using the second fixing screw 45 inserted from above in the second component 42. The length of 45 is longer than the interval of the first gap 40a. For this reason, even if the second fixing screw 45 is loosened by the female screw portion of the third component 43, the second fixing screw 45 contacts the lower surface of the first component 41 to restrict upward movement, and the second fixing screw 45 is restricted. And the third component 43 can be prevented from dropping into the cooking cabinet 20, and the second fixing screw 45 and the third component 43 can be prevented from being mixed into the food being cooked in the cooking cabinet 20. Was.

また、洗浄ノズル４０は第３構成部４３の下側から挿通される取付ねじ４６によって調理庫２０の天井壁に着脱可能に取り付けられており、第３構成部４３の下面には取付ねじ４６の頭部４６ａを収納する凹部４３ｂを形成した。洗浄ノズル４０の第３構成部４３の下面には調理庫２０内で加熱調理したときの油分等による汚れが付着する。第３構成部４３の下面に凹部４３ｂを形成していない図１４に示した実施形態では、第３構成部４３の下面と取付ねじ４６の頭部４６ａとの間に付着した油分等の汚れ（図１４のＡで示した部分）が高温の調理庫２０内で固まり、取付ねじ４６の頭部４６ａが第３構成部４３の下面に固着して、取付ねじ４６を取り外せなくなるおそれがある。図９に示したこの実施形態では、取付ねじ４６の頭部４６ａは第３構成部４３の下面に形成された凹部４３ｂに収納されている。これにより、取付ねじ４６の頭部４６ａと第３構成部４３の下面の凹部４３ｂとの接触部分に油分等による汚れが付着しにくくなり、取付ねじ４６の頭部４６ａが第３構成部４３の下面に固着しにくくなった。また、加熱調理中に飛散した油が第３構成部４３の凹部４３ｂ内に流入しても、油は凹部４３ｂの垂直に立つ周壁から流れ落ちるため、凹部４３ｂ内に油が残りにくくなった。   The cleaning nozzle 40 is detachably attached to the ceiling wall of the cooking cabinet 20 by mounting screws 46 inserted from below the third component 43, and the lower surface of the third component 43 is provided with mounting screws 46. A recess 43b for accommodating the head 46a was formed. Dirt due to oil and the like when heating and cooking in the cooking cabinet 20 adheres to the lower surface of the third component 43 of the cleaning nozzle 40. In the embodiment shown in FIG. 14 in which the concave portion 43b is not formed on the lower surface of the third component 43, dirt such as oil adhered between the lower surface of the third component 43 and the head 46a of the mounting screw 46. 14A) is hardened in the high-temperature cooking cabinet 20, and the head 46 a of the mounting screw 46 is fixed to the lower surface of the third component 43, so that the mounting screw 46 may not be removed. In this embodiment shown in FIG. 9, the head 46a of the mounting screw 46 is housed in a recess 43b formed on the lower surface of the third component 43. This makes it difficult for dirt such as oil to adhere to a contact portion between the head portion 46a of the mounting screw 46 and the concave portion 43b on the lower surface of the third component 43, and the head 46a of the mounting screw 46 is It became difficult to adhere to the lower surface. Further, even if the oil scattered during the heating and cooking flows into the concave portion 43b of the third component 43, the oil flows down from the vertically surrounding peripheral wall of the concave portion 43b, so that the oil hardly remains in the concave portion 43b.

また、取付ねじ４６は第２隙間部４０ｃを通る位置に配置され、第２構成部４２の第３周面部４２ｄの下面には取付ねじ４６が貫通する第２隙間部４０ｃの間隔を保持する間隔保持突部４２ｆが設けられている。このようにしたことで、取付ねじ４６を強く締結しても、取付ねじ４６が貫通する位置の第２隙間部４０ｃは間隔保持突部４２ｆによって間隔が保持され、第２噴射口４０ｄの開口部分が狭くなるのを防ぐことができた。なお、第３構成部４３の上面に間隔保持突部４２ｆを設けたときにも同様の作用効果を得ることができる。また、取付ねじ４６が第１隙間部４０ａを通る位置に配置されているときには、第１構成部４１の下面または第２構成部４２の第２周面部４２ｃの上面に第１隙間部４０ａの間隔を保持する間隔保持突部を設けるようにしてもよく、このようにしたときには、第１隙間部４０ａは間隔保持突部によって間隔が保持され、第１噴射口４０ｂの開口部分が狭くなるのを防ぐことができる。   Further, the mounting screw 46 is disposed at a position passing through the second gap 40c, and the lower surface of the third peripheral surface 42d of the second component 42 has an interval for maintaining the interval of the second gap 40c through which the mounting screw 46 passes. A holding projection 42f is provided. With this configuration, even when the mounting screw 46 is strongly fastened, the gap of the second gap 40c at the position where the mounting screw 46 penetrates is maintained by the spacing holding protrusion 42f, and the opening of the second injection port 40d is opened. Could be prevented from becoming narrow. The same operation and effect can be obtained even when the space holding projection 42f is provided on the upper surface of the third component 43. When the mounting screw 46 is disposed at a position passing through the first gap 40a, the space between the first gap 40a is formed on the lower surface of the first component 41 or the upper surface of the second peripheral surface 42c of the second component 42. May be provided. In such a case, the gap of the first gap portion 40a is held by the gap holding projection, and the opening of the first injection port 40b becomes narrower. Can be prevented.

この加熱調理器１０の洗浄ノズル４０は、第１噴射口４０ｂを調理庫２０内の右側部（他方の側部）に向けて開口させ、第２噴射口４０ｄを調理庫２０内の左側部（一方の側部）として食材収容室２１と熱風生成室２２とを通風可能に仕切るファンカバー２３に向けて開口させた。また、第１噴射口４０ｂは調理庫２０の天井壁となる斜め上方に開口させ、第２噴射口４０ｄをファンカバー２３となる斜め下方に開口させている。第２噴射口４０ｄから噴き出された洗浄水はファンカバー２３の汚れを洗い流しながら吸込口２３ａから対流ファン２６に吸い込まれ、吸い込まれた洗浄水は対流ファン２６によって対流する空気とともに調理庫２０内を飛散し、洗浄水の一部は再び吸込口２３ａから対流ファン２６に吸い込まれ、吸い込まれた洗浄水は対流ファン２６によって対流する空気とともに調理庫２０内を飛散し、洗浄水の一部は排水口２０ｃを通って排水タンク１４に戻されて再び洗浄ノズル４０から噴射される。   The cleaning nozzle 40 of the heating cooker 10 opens the first injection port 40b toward the right side (the other side) in the cooking chamber 20, and opens the second injection port 40d on the left side (in the cooking chamber 20).

次に、別の実施形態の洗浄ノズル４０Ａについて説明する。図１６及び図１７に示したように、この実施形態の洗浄ノズル４０Ａは、調理庫２０の天井壁の中央部から鉛直方向下向きに延出して、上下に延びる洗浄水を通す洗浄水通路４１Ａａを有した金属製の円筒形部材（筒形部材）よりなり、第１構成部４１Ａと、第１構成部４１Ａの下側に配置される第２構成部４２Ａとを上下に分割可能に備えている。洗浄ノズル４０Ａは第１構成部４１Ａの下面と第２構成部４２Ａの上面との間に形成される第１隙間部４０Ａａによって洗浄水通路４１Ａａと連通した第１噴射口４０Ａｂが形成されている。   Next, a cleaning nozzle 40A according to another embodiment will be described. As shown in FIGS. 16 and 17, the cleaning nozzle 40 </ b> A of this embodiment extends vertically downward from the central portion of the ceiling wall of the cooking cabinet 20 and has a cleaning water passage 41 </ b> Aa through which cleaning water extends vertically. A first component 41A and a second component 42A disposed below the first component 41A are provided so as to be vertically splittable. . In the cleaning nozzle 40A, a first injection port 40Ab communicating with the cleaning water passage 41Aa is formed by a first gap 40Aa formed between the lower surface of the first component 41A and the upper surface of the second component 42A.

図１７に示したように、この実施形態の洗浄ノズル４０Ａの第１構成部４１Ａは径方向の中心部に上下に延びる洗浄水の洗浄水通路４１Ａａが形成された略円筒形をし、洗浄水供給管５０を接続する継手部５１Ａを上部に一体的に備えている。第１構成部４１Ａの洗浄水通路４１Ａａは継手部５１Ａの接続通路５１Ａａを介して洗浄水供給管５０に接続されている。図１７〜図１９に示したように、第１構成部４１Ａの下面は径方向の中心部が下方に膨らむように円錐台面４１Ａｂが形成されている。   As shown in FIG. 17, the first configuration portion 41A of the cleaning nozzle 40A of this embodiment has a substantially cylindrical shape in which a cleaning water passage 41Aa extending vertically is formed at a radially central portion. A joint part 51A for connecting the supply pipe 50 is integrally provided at the upper part. The washing water passage 41Aa of the first component 41A is connected to the washing water supply pipe 50 via the connection passage 51Aa of the joint 51A. As shown in FIGS. 17 to 19, the lower surface of the first component portion 41 </ b> A is formed with a truncated conical surface 41 </ b> Ab such that a radial center portion expands downward.

図１８及び図１９に示したように、第１構成部４１Ａの円錐台面４１Ａｂの周面の右側部（一部）には下方に突出する２つの突部４１Ａｃが形成されている。２つの突部４１Ａｃの間には第１及び第２構成部４１Ａ，４２Ａとの間で第１隙間部４０Ａａが形成され、２つの突部４１Ａｃの間の第１隙間部４０Ａａは調理庫２０の右側に向けて開口している。また、２つの突部４１Ａｃは第１及び第２構成部４１Ａ，４２Ａの右側部の間に形成される第１隙間部４０Ａａの間隔を保持する機能も有している。第１構成部４１Ａの円錐台面４１Ａｂの周面の左側部には下方に突出して第２構成部４２Ａの上面に当接する間隔保持突部４１Ａｄが形成されており、間隔保持突部４１Ａｄは第１及び第２構成部４１Ａ，４２Ａの左側部の間に形成される第１隙間部４０Ａａの間隔を保持する機能を有している。   As shown in FIGS. 18 and 19, two projections 41Ac that project downward are formed on the right side (part) of the peripheral surface of the truncated cone surface 41Ab of the first component 41A. A first gap 40Aa is formed between the first and second components 41A and 42A between the two projections 41Ac, and a first gap 40Aa between the two projections 41Ac is provided in the cooking cabinet 20. It opens to the right. Further, the two protrusions 41Ac also have a function of maintaining an interval of the first gap 40Aa formed between the right sides of the first and second components 41A and 42A. On the left side of the peripheral surface of the truncated conical surface 41Ab of the first component 41A, there is formed an interval holding projection 41Ad that protrudes downward and abuts on the upper surface of the second component 42A. And a function of maintaining the interval of the first gap portion 40Aa formed between the left side portions of the second component portions 41A and 42A.

図１７に示したように、第１構成部４１Ａの洗浄水通路４１Ａａにはスペーサ４７Ａが設けられている。スペーサ４７Ａは洗浄水通路４１Ａａの内径よりも細い外径の円筒形状（筒形状）をし、スペーサ４７Ａの上端に形成されたフランジ部４７Ａａが第１構成部４１Ａの上部に形成された環状溝４１Ａｅの上面に係合して固定されている。スペーサ４７Ａは第１構成部４１Ａの円錐台面４１Ａｂより少し下側に突出しており、２つの突部４１Ａｃと間隔保持突部４１Ａｄとともに第１構成部４１Ａの下面と第２構成部４２Ａの上面との間に形成される第１隙間部４０Ａａの間隔を保持する機能を有している。スペーサ４７Ａの内側には雌ねじ部が形成されており、第２構成部４２Ａは下側から挿通される取付ねじ４６Ａをスペーサ４７Ａの雌ねじ部に螺着させることによって第１構成部４１Ａに取り付けられる。   As shown in FIG. 17, a spacer 47A is provided in the cleaning water passage 41Aa of the first component 41A. The spacer 47A has a cylindrical shape (cylindrical shape) having an outer diameter smaller than the inner diameter of the washing water passage 41Aa, and a flange portion 47Aa formed at an upper end of the spacer 47A has an annular groove 41Ae formed at an upper portion of the first component portion 41A. And is fixed by being engaged with the upper surface of the same. The spacer 47A protrudes slightly below the truncated conical surface 41Ab of the first component 41A, and together with the two projections 41Ac and the spacing holding projections 41Ad, the lower surface of the first component 41A and the upper surface of the second component 42A. It has a function of maintaining the interval between the first gap portions 40Aa formed therebetween. A female screw portion is formed inside the spacer 47A, and the second component 42A is attached to the first component 41A by screwing an attachment screw 46A inserted from below into the female screw of the spacer 47A.

図１８及び図１９に示したように、第２構成部４２Ａは第１構成部４１Ａの下部と同じ径をした略円板形をしており、第１構成部４１Ａの下面との間に洗浄水通路４１Ａａに連通する第１隙間部４０Ａａを形成させるものである。洗浄ノズル４０Ａの周面には第１隙間部４０Ａａによって第１噴射口４０Ａｂが開口して形成されている。第１噴射口４０Ａｂは間隔保持突部４１Ａｄの前後方向の両側の各々で１３０°で開口し、２つの突部４１Ａｃの間で４５°で開口している。   As shown in FIGS. 18 and 19, the second component 42A has a substantially disk shape having the same diameter as the lower portion of the first component 41A, and is cleaned between the lower surface of the first component 41A. The first gap 40Aa communicating with the water passage 41Aa is formed. A first injection port 40Ab is formed on the peripheral surface of the cleaning nozzle 40A by a first gap 40Aa. The first injection port 40Ab is opened at 130 ° on each of both sides in the front-rear direction of the interval holding projection 41Ad, and is opened at 45 ° between the two projections 41Ac.

図１７に示したように、第２構成部４２Ａの径方向の中央部には取付ねじ４６Ａを挿通させる貫通孔が形成されており、第２構成部４２Ａの下面にはこの貫通孔の周囲にざぐり穴よりなる凹部４２Ａａが形成されている。取付ねじ４６Ａは第２構成部４２Ａの下側から貫通孔を通して第１構成部４１Ａのスペーサ４７Ａの雌ねじ部に螺着されており、取付ねじ４６Ａの頭部は第２構成部４２Ａの凹部４２Ａａに収納可能となっている。これ以外については上述した実施形態の各洗浄ノズル４０と同様である。   As shown in FIG. 17, a through hole through which the mounting screw 46A is inserted is formed in the radial center of the second component 42A, and the lower surface of the second component 42A is formed around the through hole. A recess 42Aa formed by a counterbore is formed. The mounting screw 46A is screwed into the female thread of the spacer 47A of the first component 41A through the through hole from the lower side of the second component 42A, and the head of the mounting screw 46A is inserted into the recess 42Aa of the second component 42A. It can be stored. The rest is the same as the respective cleaning nozzles 40 of the above-described embodiment.

この洗浄ノズル４０Ａも上述した実施形態の洗浄ノズル４０と同様に回転等する可動部品を備えたものでないので、調理庫２０内で加熱調理をしているときに、洗浄ノズル４０Ａを調理庫２０の天井壁に取り付けた状態としても、洗浄ノズル４０Ａが油汚れで固着して動かなくなるような不具合が生じないようにすることができた。また、洗浄ノズル４０Ａは、第１構成部４１Ａの下面と第２構成部４２Ａの上面との間に形成される第１隙間部４０Ａａによって洗浄水通路４１Ａａと連通した第１噴射口４０Ａｂを形成させたので、第２構成部４２Ａを第１構成部４１Ａから分離させる（分解する）ことで第１噴射口４０Ａｂに固着した汚れを容易に洗浄することができるようになった。   Since the washing nozzle 40A does not include a movable part that rotates or the like similarly to the washing nozzle 40 of the above-described embodiment, the washing nozzle 40A is Even when the washing nozzle 40A is attached to the ceiling wall, it is possible to prevent a problem that the washing nozzle 40A is stuck by oil stains and does not move. Further, the cleaning nozzle 40A forms a first injection port 40Ab communicating with the cleaning water passage 41Aa by a first gap 40Aa formed between the lower surface of the first component 41A and the upper surface of the second component 42A. Therefore, by separating (disassembling) the second component 42A from the first component 41A, the dirt fixed to the first injection port 40Ab can be easily cleaned.

また、この洗浄ノズル４０Ａは、第１構成部４１の径方向の中央部に配置された洗浄水通路４１Ａａ内に第１隙間部４０Ａａの間隔を保持するスペーサ４７Ａを備えている。第２構成部４２Ａの下側から挿通される取付ねじ４６Ａをスペーサ４７Ａの雌ねじ部に強く締め付けるようにしても、第２構成部４２Ａの上面は２つの突部４１Ａｃと間隔保持突部４１Ａｄだけでなく径方向の中央部に配置されたスペーサ４７Ａの下端に当接することになる。これによって、第２構成部４２Ａはスペーサ４７Ａによって適切な間隔を保持された第１隙間部４０Ａａを介して第１構成部４１Ａに取付られるようになり、第１噴射口４０Ａｂから洗浄水を適切に噴射させることができるようになった。   Further, the cleaning nozzle 40A includes a spacer 47A for maintaining a space between the first gaps 40Aa in a cleaning water passage 41Aa arranged at a radially central portion of the first component 41. Even if the mounting screw 46A inserted from the lower side of the second component 42A is strongly tightened to the female screw portion of the spacer 47A, the upper surface of the second component 42A is formed only by the two protrusions 41Ac and the spacing holding protrusion 41Ad. Instead, it comes into contact with the lower end of the spacer 47A arranged at the center in the radial direction. As a result, the second component 42A is attached to the first component 41A via the first gap 40Aa maintained at an appropriate distance by the spacer 47A, and the cleaning water is appropriately supplied from the first injection port 40Ab. You can now fire.

また、この洗浄ノズル４０Ａは第２構成部４２Ａの下側から挿通される取付ねじ４６Ａによって第１構成部４１Ａを介して調理庫２０の天井壁に着脱可能に取り付けられており、第２構成部４２Ａの下面には取付ねじ４６Ａの頭部４６Ａａを収納する凹部４２Ａａを形成した。洗浄ノズル４０の第２構成部４２Ａの下面には調理庫２０内で加熱調理したときの油分等による汚れが付着する。これによって、取付ねじ４６Ａの頭部４６Ａａと第２構成部４２Ａの下面の凹部４２Ａａとの接触部分に油分等による汚れが付着しにくくなり、取付ねじ４６Ａの頭部４６Ａａが第２構成部４２Ａの下面に固着しにくくなった。また、加熱調理中に飛散した油が第２構成部４２Ａの凹部４２Ａａ内に流入しても、油は凹部４２Ａａの垂直に立つ周壁から流れ落ちるため、凹部４２Ａａ内に油が残りにくくなった。   The washing nozzle 40A is detachably attached to the ceiling wall of the cooking cabinet 20 via the first component 41A by a mounting screw 46A inserted from below the second component 42A. A concave portion 42Aa for accommodating the head portion 46Aa of the mounting screw 46A was formed on the lower surface of 42A. Dirt due to oil and the like when heating and cooking in the cooking cabinet 20 adheres to the lower surface of the second component 42A of the cleaning nozzle 40. This makes it difficult for dirt such as oil to adhere to a contact portion between the head 46Aa of the mounting screw 46A and the recess 42Aa on the lower surface of the second component 42A, and the head 46Aa of the mounting screw 46A is fixed to the second component 42A. It became difficult to adhere to the lower surface. Further, even if the oil scattered during the heating and cooking flows into the concave portion 42Aa of the second component portion 42A, the oil flows down from the vertical wall of the concave portion 42Aa, so that the oil hardly remains in the concave portion 42Aa.

この実施形態の洗浄ノズル４０Ａは、第１構成部４１Ａと、第１構成部４１Ａの下側に第２構成部４２Ａとを備えたが、これに限られるものでなく、第２構成部４２Ａの下側に第２隙間部を介して第３構成部を備えたものであってもよい。   The cleaning nozzle 40A of this embodiment includes the first component 41A and the second component 42A below the first component 41A, but is not limited thereto. A third component may be provided on the lower side via a second gap.
