The sloping portion 45b3 connects the restricting portion 45b1 and the water-conducting tube portion 45b2, and the sloping portion 45b3 is tapered downward. When the filter portion 45b of the drain perforated plate 45 is inserted into the first drain pipe 15 from the drain port 20c, the inclined portion 45b3 prevents the upper side of the water passage cylindrical portion 45b2 from being caught by the peripheral portion of the drain port 20c and deformed. have a function.

第１排水管１５の内径は４５ｍｍとなっており、フィルタ部４５ｂの規制部４５ｂ１の外径は４２ｍｍとなっており、フィルタ部４５ｂの規制部４５ｂ１が第１排水管１５に僅かな隙間で嵌合していることで、排水目皿４５は水平方向への移動が規制されて排水口２０ｃから外れにくくなっている。フィルタ部４５ｂの通水筒部４５ｂ２の外径は３０ｍｍとなっており、第１排水管１５と通水筒部４５ｂ２の周面との間には洗浄水を通過させるのに十分な隙間が形成されている。 The inner diameter of the first drain pipe 15 is 45 mm, and the outer diameter of the restricting portion 45b1 of the filter portion 45b is 42 mm. By being aligned, the drain perforated plate 45 is restricted from moving in the horizontal direction and is difficult to come off from the drain port 20c. The outer diameter of the tubular water passage portion 45b2 of the filter portion 45b is 30 mm, and a sufficient clearance is formed between the first drain pipe 15 and the circumferential surface of the tubular water passage portion 45b2 to allow the washing water to pass therethrough. there is

スタンド部４５ｃは環状の枠体４５ａの中心よりも半径方向の外側の両側に立設して形成されており、固形洗剤はフィルタ部４５ｂの上側でスタンド部４５ｃによって起立して配置可能となっている。スタンド部４５ｃは金属製の線材を屈曲加工したものであり、その間に配置した固形洗剤をできるだけ覆わないようにして、排水口２０ｃに流れる洗浄水が固形洗剤に接触しやすくしている。また、スタンド部４５ｃは排水目皿４５を持つときの持ち手部を兼ねており、排水目皿４５はスタンド部４５ｃを持って排水口２０ｃから着脱される。 The stand portions 45c are formed to stand on both radially outer sides of the center of the annular frame 45a, and the solid detergent can be placed upright by the stand portions 45c above the filter portion 45b. there is The stand part 45c is formed by bending a metal wire, and the solid detergent placed therebetween is not covered as much as possible, so that the washing water flowing through the drain port 20c can easily come into contact with the solid detergent. The stand portion 45c also serves as a handle for holding the drainage plate 45, and the drainage plate 45 can be removed from the drainage port 20c by holding the stand portion 45c.

図７に示したように、排水目皿４５の下側には補助フィルタ４６が設けられており、補助フィルタ４６は第１排水管１５における洗浄水の導入端部に配置されている。補助フィルタ４６は排水目皿４５が排水口２０ｃから外れたときでも、洗浄水を対水可能とした状態で異物が洗浄水管路に流入するのを防ぐ機能を有している。 As shown in FIG. 7 , an auxiliary filter 46 is provided below the drain perforated plate 45 , and the auxiliary filter 46 is arranged at the end of the first drain pipe 15 into which washing water is introduced. The auxiliary filter 46 has a function of preventing foreign substances from flowing into the washing water pipe while allowing the washing water to withstand water even when the drain perforated plate 45 is removed from the drain port 20c.

図１０に示したように、加熱調理器１０は制御装置５０を備えており、制御装置５０は、排水弁１７、ヒータ２５、対流ファン２６、温度センサ２７、蒸気発生装置３０、ポンプ４２及び給水弁４４に接続されている。制御装置５０はマイクロコンピュータ（図示省略）を有しており、マイクロコンピュータは、バスを介してそれぞれ接続されたＣＰＵ、ＲＡＭ、ＲＯＭ及びタイマ（いずれも図示省略）を備えている。制御装置５０は、ＲＯＭに調理庫２０内の食材を加熱調理する調理プログラムと、調理庫２０内を洗浄する洗浄プログラムを備えている。調理プログラムは、ヒータ２５と対流ファン２６を作動させて対流する熱風により食材を加熱調理するホットエアーモード調理プログラムと、対流ファン２６と蒸気発生装置３０を作動させて対流する蒸気を含んだ熱風により食材を加熱調理するスチームモード調理プログラムと、ヒータ２５と対流ファン２６と蒸気発生装置３０を作動させて対流する蒸気を含んだ高温の熱風により食材を加熱調理するコンビモード調理プログラムとの３種類の調理プログラムを備えている。なお、食材の調理に応じた調理庫２０内の設定温度、蒸気量及び調理時間を記憶させた上記の各調理プログラムがＲＯＭに予め設定されているとともに、ユーザのニーズに応じた調理庫２０内の設定温度、蒸気量及び調理時間とした各調理プログラムを設定可能となっている。また、洗浄プログラムは、洗剤を含んだ洗浄水を噴射させながら循環させる１回の洗浄モードと、洗剤を含まない洗浄水を噴射させながら循環させる３回（複数回）の濯ぎモードとを実行するものである。 As shown in FIG. 10, the heating cooker 10 includes a control device 50, which includes a drain valve 17, a heater 25, a convection fan 26, a temperature sensor 27, a steam generator 30, a pump 42 and a water supply. It is connected to valve 44 . The control device 50 has a microcomputer (not shown), and the microcomputer has a CPU, a RAM, a ROM and a timer (all not shown) connected via a bus. The control device 50 has a cooking program for cooking foodstuffs in the cooking chamber 20 and a washing program for washing the inside of the cooking chamber 20 in the ROM. The cooking program consists of a hot air mode cooking program in which the heater 25 and the convection fan 26 are operated to heat and cook the ingredients with convection hot air, and a convection fan 26 and the steam generator 30 are operated to operate the convection hot air containing steam. There are three types of cooking programs: a steam mode cooking program for heating and cooking foodstuffs, and a combination mode cooking program for heating and cooking foodstuffs with high-temperature hot air containing steam that actuates the heater 25, the convection fan 26, and the steam generator 30 to convect. It has a cooking program. In addition, each of the above cooking programs, which stores the set temperature, steam amount, and cooking time in the cooking chamber 20 according to the cooking of the ingredients, is preset in the ROM, and the cooking chamber 20 according to the needs of the user. It is possible to set each cooking program with the set temperature, steam amount and cooking time. In addition, the cleaning program includes a one-time cleaning mode in which cleansing water containing detergent is jetted and circulated, and a three-time (multiple) rinse mode in which cleansing water containing no detergent is jetted and circulated. It is.

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、仕切板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 such as a combi-mode cooking program is executed, the heater 25 and the convection fan 26 operate to turn the air in the cooking chamber 20 into hot air that circulates, and steam is sent from the steam generator 30 into the cooking chamber 20. is supplied, the food stored in the cooking chamber 20 is cooked by hot air containing steam. At this time, the oil contained in the food material is scattered inside the cooking chamber 20 together with the convection hot air, and the oil adheres to the walls of the cooking chamber 20, the partition plate 23, the support frame 24, and the like. In this type of heating cooker 10, it is desirable to maintain the inside of the cooking chamber 20 in a sanitary manner at all times, so it is preferable to clean the cooking chamber 20, for example, every day it is used. For this reason, the heating cooker 10 has a cleaning program for automatically cleaning the interior of the cooking chamber 20 .

調理庫内を洗浄するときには、調理庫２０の排水口２０ｃに設けた排水目皿４５のスタンド部４５ｃに起立した状態で固形洗剤を置いて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。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４４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内に洗浄水を貯えるようにしているときに、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 washing the inside of the cooking chamber, the solid detergent is placed on the standing portion 45c of the drain perforated plate 45 provided at the drain port 20c of the cooking chamber 20, and the washing program is executed. The washing program executes a washing mode for washing with washing water containing detergent and a three-time rinsing mode for washing with washing water containing no detergent. When the cleaning mode is started, the drain valve 17 is closed and the water supply valve 44 is opened for a predetermined period of time, so that the drain tank 14 is filled with cleansing water. When washing water is stored in the drain tank 14, the steam generator 30 is operated to supply steam into the cooking chamber 20 to remove oil and the like adhering to the peripheral wall of the cooking chamber 20. - 特許庁It is preferable to allow the dirt to float.

排水タンク１４内に洗浄水が貯まった後でポンプ４２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４１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から調理庫２０内に広範囲に拡がって吹き付けられ、調理庫２０の天井壁から周壁に沿って流れ落ちる。調理庫２０の周壁を流れ落ちた洗浄水は排水口２０ｃから第１排水管１６を通って再び排水タンク１４に戻る。排水タンク１４に戻った洗浄水はポンプ４２によって再び洗浄ノズル４０に送られ、洗浄水は調理庫２０と排水タンク１４とを循環するようになる。このとき、排水目皿４５のスタンド部４５ｃに起立した状態で置いた固形洗剤は排水口２０ｃに流れる洗浄水に徐々に溶け、洗浄水は洗剤を含むようになる。 When the pump 42 is operated after the wash water is stored in the drain tank 14 , the wash water stored in the drain tank 14 is sent to the wash nozzle 40 through the wash water supply pipe 41 . Washing water is sprayed from the washing nozzle 40 into the cooking chamber 20 in a wide range, and flows down from the ceiling wall of the cooking chamber 20 along the peripheral wall. The washing water flowing down the peripheral wall of the cooking chamber 20 returns to the drain tank 14 again through the first drain pipe 16 from the drain port 20c. The washing water returned to the drain tank 14 is sent to the washing nozzle 40 again by the pump 42, and the washing water circulates between the cooking chamber 20 and the drain tank 14. - 特許庁At this time, the solid detergent placed upright on the stand portion 45c of the drain perforated plate 45 gradually dissolves in the wash water flowing through the drain port 20c, and the wash water comes to contain the detergent.

また、洗浄プログラムを実行しているときには、ヒータ２５と対流ファン２６を作動させている。洗浄ノズル４０から噴き出された洗浄水は、対流ファン２６によって対流させている空気によってさらに調理庫２０の周壁の隅々まで吹き付けられるようになっている。また、対流ファン２６の作動とともにヒータ２５も作動させているために、調理庫２０内を対流する空気は加熱され、加熱された空気は洗浄ノズル４０から調理庫２０内に吹き付けられた洗浄水を温めるようになる。このように、洗浄プログラムを実行しているときヒータ２５と対流ファン２６とを作動させることで、洗浄ノズル４０から噴き出される洗浄水は油汚れを落としやすい高い温度状態となって、調理庫２０の周壁、仕切板２３及び支持フレーム２４の隅々まで吹き付けられるようになり、調理庫２０の周壁等に付着している油汚れを落としやすくすることができた。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４２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。 Also, when the cleaning program is being executed, the heater 25 and the convection fan 26 are operated. The washing water jetted from the washing nozzle 40 is further sprayed to every corner of the peripheral wall of the cooking chamber 20 by the air convected by the convection fan 26 . In addition, since the heater 25 is also operated together with the operation of the convection fan 26, the air convecting in the cooking chamber 20 is heated, and the heated air is washed with the washing water sprayed into the cooking chamber 20 from the washing nozzles 40. It becomes warm. By activating the heater 25 and the convection fan 26 while the cleaning program is being executed in this way, the cleaning water jetted from the cleaning nozzle 40 reaches a high temperature state that facilitates removal of oil stains. Since the oil can be sprayed to every corner of the peripheral wall of the cooking chamber 20, the partition plate 23 and the support frame 24, the oil stains adhering to the peripheral wall of the cooking chamber 20 can be easily removed. When the washing mode of the washing program is executed for a predetermined period of time, the heater 25, the convection fan 26 and the pump 42 are stopped and the drain valve 17 is opened to drain the cleaning water containing the detergent in the drain tank 14.

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４４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４２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４１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から噴き出される洗浄水は調理庫２０の周壁、仕切板２３及び支持フレーム２４の隅々まで吹き付けられるようになり、洗浄モードに吹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４２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 rinse mode is executed. In the rinsing mode, the drain valve 17 is closed and the water supply valve 44 is opened for a predetermined time so that the drain tank 14 is filled with wash water for rinsing. After that, when the pump 42 is operated, the washing water stored in the drain tank 14 is sent to the washing nozzle 40 through the washing water supply pipe 41, and is ejected from the washing nozzle 40 in the same manner as in the washing mode described above. The washing water can be sprayed to every corner of the peripheral wall of the cooking chamber 20, the partition plate 23 and the support frame 24, so that the washing water containing the detergent sprayed in the washing mode can be washed away. 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 heater 25, the convection fan 26 and the pump 42 are stopped, the drain valve 17 is opened, and the rinse water in the drain tank 14 is drained. In addition, in this embodiment, the washing program is completed by executing the rinsing mode three times as a plurality of times.

上記のように構成した加熱調理器１０は、食材を加熱調理する調理庫２０と、調理庫２０の底部に設けた排水口２０ｃと、調理庫２０の天井部に設けられて洗浄水を噴出する洗浄ノズル４０と、排水口２０ｃと洗浄ノズル４０とを接続する洗浄水管路と、洗浄水管路に介装されて洗浄水を洗浄ノズル４０に送出するポンプ４２とを備えている。この加熱調理器１０は、調理庫２０内に固形洗剤を入れた状態でポンプ４２を作動させて洗浄水を洗浄ノズル４０から噴出させるようにした調理庫２０の洗浄機能を有している。この加熱調理器１０においては、排水口２０ｃには洗浄水管路に異物の混入を防いだ状態で通水させるフィルタ部４５ｂを有した排水目皿４５を着脱可能に設け、排水目皿４５にはフィルタ部４５ｂを塞がないように固形洗剤を起立させるスタンド部４５ｃを設けた。これにより、調理庫２０の排水口２０ｃが固形洗剤によって通水できないように塞がれるのを防ぐだけでなく、固形洗剤が排水口２０ｃを通過する洗浄水に溶けるようになった。 The heating cooker 10 configured as described above includes a cooking chamber 20 for cooking foodstuffs, a drain port 20c provided at the bottom of the cooking chamber 20, and a ceiling portion of the cooking chamber 20 for ejecting washing water. A washing nozzle 40 , a washing water pipeline connecting the drain port 20 c and the washing nozzle 40 , and a pump 42 interposed in the washing water pipeline to send the washing water to the washing nozzle 40 are provided. This heating cooker 10 has a cleaning function for the cooking chamber 20 in which the pump 42 is operated in a state where the solid detergent is put in the cooking chamber 20 to eject cleaning water from the cleaning nozzle 40.例文帳に追加In this heating cooker 10, a drainage perforated plate 45 having a filter portion 45b that allows water to pass through the washing water pipe while preventing foreign matter from entering is detachably provided at the drainage port 20c. A stand portion 45c is provided for standing up the solid detergent so as not to block the filter portion 45b. This not only prevents the drain port 20c of the cooking chamber 20 from being blocked by the solid detergent, but also allows the solid detergent to dissolve in the wash water passing through the drain port 20c.

また、調理庫２０でコンビモードで加熱調理を実行しているときに、調理庫２０内の排水口２０ｃが塞がれると、調理庫２０内が陽圧となるおそれがあった。この場合に、蒸気発生容器３１の水位が低下して加熱体が過熱状態となったり、調理庫２０内の空気が蒸気発生容器３１に逆流するおそれがあった。この加熱調理器１０では、調理庫２０内に収容した食材が調理の過程で排水目皿４５の上側に落下しても、排水目皿４５には上側にワイヤ状のスタンド部４５ｂが立設しているので、落下した食材が排水目皿４５のフィルタ部４５ｂを塞ぐのを防ぐことができた。特に、キャベツや白菜等の大きな葉物の野菜が排水目皿４５の上側に覆い被さるように落下しても、排水目皿４５のフィルタ部４５ｂはスタンド部４５ｂによって葉物の野菜によって塞がれないようになり、調理庫２０内が陽圧となるのを防ぐことができた。 Moreover, if the drain port 20c in the cooking chamber 20 is blocked while cooking is being performed in the combination mode in the cooking chamber 20, the pressure inside the cooking chamber 20 may become positive. In this case, there is a possibility that the water level in the steam generating vessel 31 will drop and the heating element will be overheated, or that the air inside the cooking chamber 20 will flow back into the steam generating vessel 31 . In this heating cooker 10, even if the food stored in the cooking chamber 20 falls to the upper side of the drain perforated plate 45 during the cooking process, the drain perforated plate 45 is provided with a wire-shaped stand portion 45b erected on the upper side. As a result, it is possible to prevent the food that has fallen from clogging the filter portion 45b of the drain perforated plate 45.例文帳に追加In particular, even if large leafy vegetables such as cabbage and Chinese cabbage fall so as to cover the drainage perforated plate 45, the filter portion 45b of the drainage perforated plate 45 is blocked by the leafy vegetables by the stand portion 45b. It became possible to prevent the inside of the cooking chamber 20 from becoming a positive pressure.

また、排水目皿４５のフィルタ部４５ｂは第１排水管１５内に凹むように形成され、フィルタ部４５ｂの下部には第１排水管１５の内周面との間に通水可能な隙間が形成される通水筒部４５ｂ２が設けられている。調理庫２０で加熱調理の過程で落下した食材の欠片が洗浄中にフィルタ部４５ｂの底部に溜まっても、洗浄水はフィルタ部４５ｂの通水筒部４５ｂ２の側面から洗浄水管路の第１排水管１５との間の隙間を通って第１排水管１５に流れていくので、排水目皿４５のフィルタ部４５ｂに食材の欠片が詰まって洗浄水が流れなくなるのを防ぐことができる。また、調理庫２０の洗浄後にフィルタ部４５ｂに溜まる食材の欠片等を取り除き忘れたときに、調理庫２０内の空気が排水目皿４５のフィルタ部４５ｂの通水筒部４５ｂ２の側面を通って第１排水管１５から排出されるので、調理庫２０内が陽圧となるのを防ぐことができた。 In addition, the filter portion 45b of the drainage mesh plate 45 is formed so as to be recessed in the first drain pipe 15, and the lower portion of the filter portion 45b and the inner peripheral surface of the first drain pipe 15 have a gap through which water can flow. A formed water-conducting tubular portion 45b2 is provided. Even if pieces of food that have fallen during the cooking process in the cooking chamber 20 accumulate at the bottom of the filter portion 45b during washing, the wash water is discharged from the side surface of the water passage tube portion 45b2 of the filter portion 45b to the first drain pipe of the wash water pipe. 15 and flows into the first drain pipe 15, it is possible to prevent the filter part 45b of the drainage perforated plate 45 from clogging with pieces of food and preventing the washing water from flowing. In addition, when the food pieces accumulated in the filter portion 45b are forgotten to be removed after washing the cooking chamber 20, the air in the cooking chamber 20 passes through the side surface of the water passage cylinder portion 45b2 of the filter portion 45b of the drain perforated plate 45, Since it is discharged from 1 drain pipe 15, it was possible to prevent the inside of the cooking chamber 20 from becoming a positive pressure.

また、フィルタ部４５ｂの上部には第１排水管１５の内周面に接近した位置に配置されて排水目皿４５の水平方向への移動を規制する規制部４５ｂ１が設けられている。調理庫２０内を洗浄しているときに、調理庫２０内には対流ファン２６によって洗浄水が飛散しており、排水目皿４５が飛散している洗浄水とともに排水口２０ｃから外れるおそれがあるが、フィルタ部４５ｂの規制部４５ｂ１が第１排水管１５の内周面に僅かな隙間で嵌合しているため、排水目皿４５が排水口２０ｃから外れにくくすることとができた。 In addition, a restricting portion 45b1 is arranged at a position close to the inner peripheral surface of the first drain pipe 15 on the upper portion of the filter portion 45b to restrict the horizontal movement of the drainage mesh plate 45. As shown in FIG. When the inside of the cooking chamber 20 is being washed, the washing water is scattered in the cooking chamber 20 by the convection fan 26, and there is a possibility that the drain perforated plate 45 will come off from the drain port 20c together with the scattered washing water. However, since the regulating portion 45b1 of the filter portion 45b is fitted to the inner peripheral surface of the first drain pipe 15 with a small gap, the drain mesh plate 45 is less likely to come off from the drain port 20c.

また、フィルタ部４５ｂの通水筒部４５ｂ２の上側には、下側に進むに従い径が細くなる傾斜部４５ｂ３が設けられている。排水目皿４５のフィルタ部４５ｂを排水口２０ｃから第１排水管１５に挿入するときに、通水筒部４５ｂ２の上側が排水口２０ｃの周縁部に引っ掛かって変形しにくくすることができた。 In addition, an inclined portion 45b3 whose diameter becomes smaller toward the lower side is provided on the upper side of the water passage tube portion 45b2 of the filter portion 45b. When inserting the filter portion 45b of the drain perforated plate 45 into the first drain pipe 15 from the drain port 20c, the upper side of the water passage cylindrical portion 45b2 is prevented from being caught on the peripheral portion of the drain port 20c and deformed.

また、洗浄水管路を構成する第１排水管１５には排水目皿４５の下側に補助フィルタ４６が設けられている。これにより、排水目皿４５が排水口２０ｃから外れても、異物が第１排水管１５を通ってポンプ４２に流入しないようになった。さらに、スタンド部４５ｃが持ち手部を兼ねるようにしたので、スタンド部４５ｃを把持して排水目皿４５を着脱しやすくすることができた。 In addition, an auxiliary filter 46 is provided below the drain perforated plate 45 in the first drain pipe 15 that constitutes the washing water pipeline. As a result, even if the drain perforated plate 45 is disengaged from the drain port 20c, foreign matter is prevented from flowing into the pump 42 through the first drain pipe 15.例文帳に追加Furthermore, since the stand portion 45c also serves as a handle portion, the drainage perforated plate 45 can be easily attached and detached by gripping the stand portion 45c.

排水目皿４５は図９に示した実施形態に限られるものでなく、図１１（ａ）に示したように、上述した図９に示した実施形態の傾斜部４５ｂ３をなくしたものであってもよい。また、また、図１１（ｂ）に示したように、上述した図９に示した実施形態の規制部４５ｂ１と傾斜部４５ｂ３とをなくしたものであってもよい。図１１（ｃ）に示したように、排水目皿４５のフィルタ部４５ｂを浅く凹むように形成したときには、排水目皿４５が排水口２０ｃから外れるおそれがあるが、排水目皿４５のフィルタ部４５ｂの下側に排水口２０ｃに挿入される規制部４５ｂ１を設けるようにして、排水目皿４５を排水口２０ｃから外れにくくするようにしてもよい。また、図１１（ｄ）に示したように、フィルタ部４５ｂの排水口２０ｃの周縁部を下側に延出させるようにして規制部４５ｂ１を一体的に形成するようにしてもよい。 The drainage perforated plate 45 is not limited to the embodiment shown in FIG. 9, and as shown in FIG. good too. Further, as shown in FIG. 11(b), the restricting portion 45b1 and the inclined portion 45b3 of the embodiment shown in FIG. 9 may be eliminated. As shown in FIG. 11(c), when the filter portion 45b of the drain plate 45 is formed to be shallowly recessed, the drain plate 45 may come off from the drain port 20c. A regulating portion 45b1 inserted into the drain port 20c may be provided below the drain port 45b to make it difficult for the drain plate 45 to come off from the drain port 20c. Further, as shown in FIG. 11(d), the restricting portion 45b1 may be integrally formed by extending the peripheral portion of the drain port 20c of the filter portion 45b downward.
