An object of the present invention is to prevent water adhering to the inner glass of a door of a heating cooker from scattering and polluting the surroundings.

上記課題を解決するために、本発明は、ハウジング内にて前面に食材を出し入れする開口部を有した調理庫と、ハウジングに鉛直軸線回りに回動可能に支持されて開口部を開閉自在に塞ぐ扉本体と、扉本体の調理庫側に設けられたインナガラスと、インナガラスの下側に設けられて、インナガラスから落下した水を受けて底部に設けた排水口から排出する第１樋部材と、第１樋部材の排水口を扉本体の開閉に応じて開閉する排水口開閉装置と、ハウジングの前面にて扉本体を閉じたときに第１樋部材の排水口の下側に設けられて排水口開閉装置により開放された排水口から排出される水を受ける第２樋部材とを備えた加熱調理器であって、第１樋部材の底部には下方に延びて下端に排水口が形成された排水筒部を備え、排水筒部の下端の排水口を水平方向の一方が低くなるように傾斜させたことを特徴とする加熱調理器。 In order to solve the above-mentioned problems, the present invention provides a cooking cabinet having an opening for putting foods in and out of a front surface in a housing, and a housing which is rotatably supported on a vertical axis and is capable of opening and closing the opening. A door body to be closed, an inner glass provided on the cooking cabinet side of the door body, and a first gutter provided below the inner glass and receiving water dropped from the inner glass and discharging the water from a drain port provided at the bottom. A member, a drain opening / closing device for opening / closing a drain port of the first gutter member in response to opening / closing of the door body, and provided below the drain port of the first gutter member when the door body is closed at the front of the housing. And a second gutter member for receiving water discharged from the drain port opened by the drain port opening / closing device, wherein the bottom portion of the first gutter member extends downward and has a drain port at the lower end. The drainage cylinder part with Cooker, characterized in that one of the horizontal direction is inclined to be lower.

上記のように構成した加熱調理器においては、第１樋部材の底部には下方に延びて下端に排水口が形成された排水筒部を備え、排水筒部の下端の排水口を水平方向の一方が低くなるように傾斜させたので、第１樋部材の水は排水筒部の水平方向の一方に沿って排水口から流れ落ち、第１樋部材で受けた水を周囲に飛散させることなく第２樋部材に流すことができ、加熱調理器の周囲に水を飛散させないようにすることができた。 In the cooking device configured as described above, the bottom of the first gutter member is provided with a drainage tube portion that extends downward and has a drainage port formed at the lower end, and the drainage port at the lower end of the drainage cylinder is disposed in the horizontal direction. Since one side is inclined to be lower, the water of the first gutter member flows down from the drainage port along one of the horizontal directions of the drainage tube portion, and the water received by the first gutter member is dispersed without scattering to the surroundings. The water could flow through the two gutter members, and water could not be scattered around the cooking device.

上記のように構成した加熱調理器においては、排水筒部の下端の排水口は後側が低くなるように傾斜しており、排水口開閉装置は排水筒部の下側に配置されて排水筒部の下側を開閉自在に覆う止水板と、止水板の上面に設けられたパッキンシートと、パッキンシートの上面における排水筒部より外側に設けられてパッキンシートを止水板に取り付けるための取付板とを備え、止水板は排水筒部より前側で水平軸線回りに回動可能に支持され、止水板の上面のパッキンシートを排水口に密着させた状態から止水板を下側に回動させるようにして排水口を開放するようにしたものであり、取付板には排水筒部が配置される位置よりも後側に通水用の通水切欠部を形成するのが好ましい。このようにしたときには、第１樋部材で受けた水は排水筒部の後部に沿って排水口から流れ落ち、第１樋部材で受けた水を周囲に飛散させることなくパッキンシートの上面に流すことができるとともに、パッキンシートの上面に流れ落ちた水は通水切欠部によって取付板に遮られることなく第２樋部材に流れ落ちるようになり、加熱調理器の周囲に水を飛散させないようにすることができた。 In the heating cooker configured as described above, the drain port at the lower end of the drain cylinder is inclined so that the rear side is lower, and the drain opening / closing device is disposed below the drain cylinder and the drain cylinder is disposed. A water blocking plate that covers the lower side of the water blocking plate, a packing sheet provided on the top surface of the water blocking plate, and a packing sheet provided on the top surface of the packing sheet outside the drainage cylinder for attaching the packing sheet to the water blocking plate. The water stop plate is supported rotatably around the horizontal axis at the front side of the drainage cylinder, and the packing sheet on the upper surface of the water stop plate is placed on the lower side from the state where the packing sheet is in close contact with the drain port. It is preferable that the drainage port is opened by rotating the drainage pipe, and it is preferable that the mounting plate is formed with a water cutout portion for water flow behind the position where the drainage pipe portion is arranged. . In this case, the water received by the first gutter member flows down from the drain port along the rear part of the drainage tube portion, and the water received by the first gutter member flows to the upper surface of the packing sheet without being scattered around. And water flowing down on the upper surface of the packing sheet flows down to the second gutter member without being blocked by the mounting plate by the water cut-out portion, so that water is not scattered around the heating cooker. did it.

Was completed.

上記のように構成した加熱調理器においては、パッキンシートの後縁には排水筒部が配置される左右方向の位置にて斜め下方に突き出る突出部を形成するのが好ましい。排水口からパッキンシートの上面に流れ落ちた水の一部は第２樋部材に流れ落ちずに表面張力によってパッキンシートの後縁に多く残るおそれがあるが、パッキンシートの後縁には排水筒部が配置される左右方向の位置にて斜め下方に突き出る突出部が形成されているので、パッキンシートの後縁に残る水は突出部に集まって第２樋部材に流れ落ちるようになり、パッキンシートの後縁に残る水を少なくすることができた。 In the cooking device configured as described above, it is preferable to form a projecting portion projecting obliquely downward at the left and right position where the drainage tube portion is disposed at the rear edge of the packing sheet. Part of the water that has flowed down from the drain port to the upper surface of the packing sheet may not flow down to the second gutter member and may remain at the trailing edge of the packing sheet due to surface tension. Since the projecting portion projecting obliquely downward is formed at the position in the left-right direction where it is arranged, the water remaining on the trailing edge of the packing sheet gathers at the projecting portion and flows down to the second gutter member, and the water flows behind the packing sheet. Water remaining on the edge was reduced.

Even when the water stop plate 42 is in the open position, the rear side is inclined so as to be lower. When the water stop plate 42 is set to the open position and the water is discharged from the drain port 33b, the water is removed from the packing sheet 43. It flows on the upper side to the rear side. The mounting plate 44 for mounting the packing sheet 43 to the water blocking plate 42 has a semicircular notch 44a formed so that the drain port 33b at the tip of the drainage tube portion 33a can be abutted against the packing sheet 43. A water cut-out portion 44b is formed behind the cut-out portion 44a to allow water to flow to the rear side. The water that has flowed down from the drainage port 33b to the upper surface of the packing sheet 43 flows down to the second gutter member 11b without being blocked by the mounting plate 44 by the water flow notch 44b, and the water scatters around the heating cooker 10. Could be difficult.

また、止水板４２の左右方向の両側には上側に折り曲げた折曲部４２ｂが形成されているので、止水板４２の上側のパッキンシート４３を流れ落ちる水が左右に流れ落ちないようになった。なお、止水板４２の左右両側に折曲部４２ｂを形成するようにしたものに限られるものでなく、止水板４２の左側または右側に折曲部４２ｂを形成するようにしたものであってもよい。 Further, since the bent portion 42b which is bent upward is formed on both sides in the left-right direction of the water stop plate 42, water flowing down the packing sheet 43 on the upper side of the water stop plate 42 is prevented from flowing down left and right. . The bent portions 42b are not limited to the bent portions 42b formed on both the left and right sides of the water stop plate 42, and the bent portions 42b are formed on the left or right side of the water stop plate 42. You may.

また、止水板４２には排水筒部３３ａの下側に排水筒部３３ａの外径よりも大きな凹部４２ａが形成されている。止水板４２の排水筒部３３ａの下端の排水口３３ｂに対する角度の精度が高くないときに、止水板４２の上面のパッキンシート４３と排水筒部３３ａの下端の排水口３３ｂとの間に隙間が生じるおそれがある。止水板４２の上面のパッキンシート４３を排水筒部３３ａに押しつけたときに、パッキンシート４３は止水板４２の凹部４２ａ内で排水筒部３３ａに密着できるように適度に弾性変形するので、排水口３３ｂから水が漏出するのを防ぐことができた。なお、この実施形態では凹部４２ａは止水板４２に形成した貫通孔であるが、これに限られるものでなく、止水板４２の厚み方向に凹むように形成したものであってもよい。 Further, a concave portion 42a larger than the outer diameter of the drainage tube portion 33a is formed below the drainage tube portion 33a in the water stop plate 42. When the accuracy of the angle of the lower end of the water stop plate 42 with respect to the drain outlet 33b of the drain cylinder portion 33a is not high, between the packing sheet 43 on the upper surface of the water stop plate 42 and the drain outlet 33b at the lower end of the drain cylinder portion 33a. Gaps may be created. When the packing sheet 43 on the upper surface of the water blocking plate 42 is pressed against the drainage tube portion 33a, the packing sheet 43 is appropriately elastically deformed so as to be able to adhere to the drainage tube portion 33a within the concave portion 42a of the water stopping plate 42. It was possible to prevent water from leaking from the drain 33b. In this embodiment, the concave portion 42 a is a through hole formed in the water blocking plate 42, but is not limited thereto, and may be formed to be recessed in the thickness direction of the water blocking plate 42.

また、パッキンシート４３の後縁には排水筒部３３ａが配置される左右方向の位置にて斜め下方に突き出る突出部４３ａが形成されている。排水口３３ｂからパッキンシート４３の上面に流れ落ちた水の一部は第２樋部材１１ｂに流れ落ちずに表面張力によってパッキンシート４３の後縁に多く残るおそれがあるが、パッキンシート４３の後縁には排水筒部３３ａが配置される左右方向の位置にて斜め下方に突き出る突出部４３ａが形成されているので、パッキンシート４３の後縁に残る水は突出部４３ａに集まって第２樋部材１１１ｂに流れ落ちるため、パッキンシート４３の後縁に残る水を少なくすることができた。 A projection 43a is formed on the rear edge of the packing sheet 43 so as to project obliquely downward at a position in the left-right direction where the drainage tube 33a is disposed. A portion of the water that has flowed down from the drain port 33b to the upper surface of the packing sheet 43 may not flow down to the second gutter member 11b, but may remain much at the trailing edge of the packing sheet 43 due to surface tension. Is formed with a projecting portion 43a projecting obliquely downward at the position in the left-right direction where the drainage tube portion 33a is disposed, so that water remaining on the trailing edge of the packing sheet 43 collects in the projecting portion 43a and the second gutter member 111b As a result, water remaining at the trailing edge of the packing sheet 43 could be reduced.
