Description
本発明は、食器を洗浄する食器洗浄機に関する。 The present invention relates to a dishwasher for washing dishes.
従来、洗浄する食器を出し入れするための開口部が上面に形成された洗浄槽と、洗浄槽の前面側に取り付けられた前板と、洗浄槽を収容する筐体と、洗浄槽が筐体に収容された際に洗浄槽の開口部を閉蓋するように筐体の内部に配置された蓋体とを備えたものが知られている
（例えば、特許文献１参照。）。
Conventionally, a cleaning tank in which an opening for taking in and out dishes to be cleaned is formed on the upper surface, a front plate attached to the front side of the cleaning tank, a housing for storing the cleaning tank, and a cleaning tank in the housing A device provided with a lid disposed inside a housing so as to close an opening of a cleaning tank when housed is known (see, for example, Patent Document 1).
この種の食器洗浄機では、一般的に、洗浄槽と前板又は筐体との間に形成された空間に、食器洗浄機を作動させるための内部機器が配置されている。 In this type of dishwasher, an internal device for operating the dishwasher is generally disposed in a space formed between the washing tank and the front plate or the casing.
ところで、特許文献１に記載の食器洗浄機では、洗浄槽の開口部の周囲に形成したフランジ部と筐体内部に配置された蓋体との間をシール部材で封止することによって、洗浄槽内部の空間を密閉状態にして、洗浄水を洗浄槽の外部に漏出しないようにしている。 By the way, in the dishwasher of patent document 1, a washing tank is sealed by sealing between the flange part formed in the circumference | surroundings of the opening part of the washing tank, and the cover body arrange | positioned inside a housing | casing. The internal space is hermetically sealed so that the washing water does not leak out of the washing tank.
しかし、フランジ部と蓋体との間のシール部材が破損していた等の理由で密閉が十分になされていない場合には、フランジ部のシール部よりも外方に水が溜まり、その水がフランジ部から洗浄槽の外にあふれることで、美観を損ねるような汚れの原因になってしまうおそれがあった。また、その水が洗浄槽と前板又は筐体との間に流れ込み、内部機器の錆や故障の原因となるおそれがあった。 However, if the sealing member between the flange part and the lid is damaged or the like is not sufficiently sealed, water accumulates outside the sealing part of the flange part, and the water Overflowing from the flange part to the outside of the washing tank may cause stains that impair the appearance. Further, the water may flow between the cleaning tank and the front plate or the casing, which may cause rusting or failure of the internal equipment.
本発明は以上の点に鑑みてなされたものであり、漏水が生じた場合であっても、汚れや内部機器の錆及び故障の発生を防止することができる食器洗浄機を提供することを目的とする。 The present invention has been made in view of the above points, and an object of the present invention is to provide a dishwasher capable of preventing the occurrence of dirt, rusting of internal equipment and failure even when water leakage occurs. And
上記目的を達成するために、本発明の食器洗浄機は、洗浄する食器を出し入れするための開口部が上面に形成された洗浄槽と、洗浄槽の開口部を閉蓋する蓋体と、洗浄槽の前面側に取り付けられた前板と、前方に開放部が形成され、該開放部から洗浄槽を出し入れ自在に収容する筐体とを備えた食器洗浄機であって、洗浄槽は、上縁から外方に向かって延設されたフランジ部と、洗浄槽と蓋体とのシール部よりも外方でフランジ部を貫く水抜き孔とを有し、水抜き孔の下方に配置され、水抜き孔から流れ込んだ水を洗浄槽と前板又は筐体との間の空間内の内部機器が配置されていない位置に導く導流部材を備えていることを特徴とする。 In order to achieve the above object, a dishwasher according to the present invention includes a washing tank having an opening formed on the upper surface for taking in and out dishes to be washed, a lid for closing the opening of the washing tank, and a washing A dishwasher comprising a front plate attached to the front side of a tank, and a housing formed with an open part in the front, in which a washing tank can be inserted and removed freely. A flange portion extending outward from the edge, and a drain hole penetrating the flange portion outside the seal portion between the cleaning tank and the lid, and disposed below the drain hole, A flow guide member is provided that guides water flowing from the drain hole to a position in the space between the cleaning tank and the front plate or the housing where no internal device is arranged.
このように、本発明の食器洗浄機では、シール部よりも外方で洗浄槽のフランジ部に水抜き孔が形成されているので、フランジ部に水が溜まってしまった場合であっても、その水は水抜き孔に流れ込む。そのため、洗浄水がフランジ部に溜まってフランジ部から洗浄槽の外にあふれることがないので、美観を損ねるような汚れが生じてしまうことがない。 Thus, in the dishwasher of the present invention, since the drain hole is formed in the flange portion of the washing tank outside the seal portion, even when water has accumulated in the flange portion, The water flows into the drain hole. For this reason, the cleaning water does not accumulate in the flange portion and overflow from the cleaning tank to the outside of the cleaning tank, so that no dirt that impairs the appearance is generated.
また、水抜き孔に流れ込んだ水は、導流部材によって洗浄槽と前板又は筐体との間の空間内の内部機器が配置されていない位置に導かれるので、内部機器が水に濡れることがなく、内部機器に錆や故障が発生することがない。 In addition, the water that has flowed into the drain hole is guided to the position where the internal device is not arranged in the space between the cleaning tank and the front plate or the case by the flow guide member, so that the internal device gets wet with water. There is no rust and failure in the internal equipment.
したがって、本発明の食器洗浄機によれば、漏水が生じた場合であっても、汚れや内部機器の錆及び故障の発生を防止することができる。 Therefore, according to the dishwasher of this invention, even if it is a case where a water leak arises, generation | occurrence | production of a stain | pollution | contamination, the rust of an internal apparatus, and a failure can be prevented.
本発明の食器洗浄機においては、洗浄槽が筐体に収納された際に洗浄槽が引き出されることを制限するロック機構を備え、ロック機構は、洗浄槽に移動可能に設けられた係合部と、筐体に設けられた被係合部とを有し、係合部は、ロック状態と非ロック状態を切り替える際に、水抜き孔を貫くように移動することが好ましい。 In the dishwasher of the present invention, the dishwasher includes a lock mechanism that restricts the washing tank from being pulled out when the washing tank is housed in the housing, and the lock mechanism is movably provided in the washing tank. And an engaged portion provided in the housing, and the engaging portion preferably moves so as to penetrate the drain hole when switching between the locked state and the unlocked state.
このように、水抜き孔をロック機構の一部として構成すれば、水抜き孔を独立して形成する必要がなくなるので、装置の大型化や生産コストの増加を防ぐことができる。 In this way, if the drain hole is configured as a part of the lock mechanism, it is not necessary to form the drain hole independently, so that the apparatus can be prevented from being increased in size and production cost.
本発明の食器洗浄機においては、導流部材は、洗浄槽の外周面に立設された板状の部材であり、導流部材の前後方向の幅は、水抜き孔に流れ込んだ水の流れにおける下流側ほど狭くなり、導流部材の前側の縁は、水抜き孔に流れ込んだ水の流れにおける下流側ほど洗浄槽に近接することが好ましい。 In the dishwasher of the present invention, the flow guide member is a plate-like member erected on the outer peripheral surface of the cleaning tank, and the width in the front-rear direction of the flow guide member is the flow of water flowing into the drain hole. It is preferable that the downstream side becomes narrower, and the front edge of the flow guide member is closer to the washing tank toward the downstream side in the flow of water flowing into the drain hole.
洗浄水等の液体は接している物体に沿って流れるので、このように構成すれば、水抜き孔に流れ込んだ水は、導流部材の前端部の縁まで流れてきても、導流部材の縁に沿って下方に流れ、最後には洗浄槽の外周面に導かれ、その後、外周面に沿って下方へ流れることになる。その結果、水抜き孔に流れ込んだ水が飛び散ることがなくなるので、さらに確実に内部機器の錆や故障の発生を防止できるようになる。 Since liquid such as washing water flows along the contacted object, the water flowing into the drainage hole can flow to the edge of the front end portion of the flow guide member. It flows downward along the edge, and finally is guided to the outer peripheral surface of the cleaning tank, and then flows downward along the outer peripheral surface. As a result, the water that has flowed into the drain hole is not scattered, so that it is possible to more reliably prevent rusting and failure of the internal equipment.
以下、図面を参照して、本発明の実施形態に係る食器洗浄機について説明する。 Hereinafter, a dishwasher according to an embodiment of the present invention will be described with reference to the drawings.
まず、図１を参照して、食器洗浄機１の概略構成について説明する。 First, a schematic configuration of the dishwasher 1 will be described with reference to FIG.
図１に示すように、食器洗浄機１は、システムキッチンに組み込んで設置されるビルトイン式のものである。食器洗浄機１の筐体２前方には開放部が形成されており、筐体２の内部に収容されている洗浄槽３は、その開放部から出し入れ自在となっている。 As shown in FIG. 1, the dishwasher 1 is a built-in type that is installed in a system kitchen. An open portion is formed in front of the housing 2 of the dishwasher 1, and the washing tub 3 accommodated in the housing 2 can be freely inserted and removed from the open portion.
洗浄槽３の底部側には、洗浄水を噴出する洗浄ノズル４が設けられている。洗浄槽３の背面側には、洗浄槽３内の食器を乾燥させるための乾燥用空気を導入する乾燥ダクト５及び乾燥ファン６が設けられている。 A cleaning nozzle 4 for ejecting cleaning water is provided on the bottom side of the cleaning tank 3.

The lower nozzle 11 is turned by the reaction force of the washing water supplied from the washing / drainage pump 9.
センターノズル１２は、下ノズル１１と一体に回転する下半部１２ａと、この下半部１２ａに上下動自在に挿設された上半部１２ｂとで構成されている。洗浄・排水ポンプ９から洗浄水が供給されたとき、センターノズル１２は下ノズル１１と共に旋回しつつ水圧によって上半部１２ｂが上方にのびるようになっている。そして、センターノズル１２の下半部１２ａ及び上半部１２ｂから食器カゴ１０に向けて洗浄水が噴出される。 The center nozzle 12 includes a lower half portion 12a that rotates integrally with the lower nozzle 11, and an upper half portion 12b that is inserted in the lower half portion 12a so as to be movable up and down. When cleaning water is supplied from the cleaning / drainage pump 9, the center nozzle 12 rotates with the lower nozzle 11, and the upper half 12 b extends upward by water pressure. Then, washing water is ejected from the lower half 12 a and the upper half 12 b of the center nozzle 12 toward the tableware basket 10.
洗浄槽３は、内部で食器の洗浄を行う洗浄槽本体部３ａと、前面の左右側縁から前方側に延設された一対の板状の扉材取付部３ｂとを有している。洗浄槽本体部３ａの上方部は、前方に突出した形状になっており、食器の洗浄の開始及び停止等の操作を行うための操作パネル１３が固定されている。洗浄槽３の前面側であって操作パネル１３の下側となる位置には、操作パネル１３及び扉材取付部３ｂを介して、扉材１４が固定されている。 The cleaning tank 3 includes a cleaning tank main body 3a for cleaning dishes therein, and a pair of plate-shaped door member mounting portions 3b extending forward from the left and right side edges of the front surface. The upper part of the washing tank main body 3a has a shape protruding forward, and an operation panel 13 for performing operations such as starting and stopping washing of tableware is fixed.

Further, the first flow guide member 17 has a shape that inclines stepwise toward the second flow guide member 18 side (side away from the internal device E2) in the left-right direction and does not tilt in the front-rear direction.
第２導流部材１８は、洗浄槽３の外周面に立設された板状の部材であり、洗浄槽３の下方部に配置されている内部機器Ｅ３の上方で内部機器Ｅ３を覆うように配置されている。また、第２導流部材１８は、左右方向においては第１導流部材１７側（内部機器Ｅ３から離れる側）に向かって段階的に傾斜し、前後方向においては傾斜しない形状となっている。 The second flow guide member 18 is a plate-like member erected on the outer peripheral surface of the cleaning tank 3 so as to cover the internal device E3 above the internal device E3 arranged in the lower part of the cleaning tank 3. Has been placed. In addition, the second flow guide member 18 has a shape that inclines stepwise toward the first flow guide member 17 side (side away from the internal device E3) in the left-right direction and does not tilt in the front-rear direction.
図４に示すように、第３導流部材１９は、水抜き孔３ｅの側縁から下方に延びる一対の板状の板状部１９ａを有している。また、図５に示すように、第３導流部材１９は、一対の板状部１９ａに挟まれた空間を閉蓋するとともに、水抜き孔３ｅを正面側から覆い隠すカバー部１９ｂを有している。板状部１９ａは洗浄槽３の外周面に立設され、カバー部１９ｂは、ネジ１９ｃによって第４導流部材２０を介して洗浄槽３に固定されている。 As shown in FIG. 4, the third flow guide member 19 has a pair of plate-like plate portions 19 a extending downward from the side edge of the drain hole 3 e. As shown in FIG. 5, the third flow guide member 19 has a cover portion 19b that closes the space between the pair of plate-like portions 19a and covers the drain hole 3e from the front side. ing. The plate-like portion 19a is erected on the outer peripheral surface of the cleaning tank 3, and the cover portion 19b is fixed to the cleaning tank 3 via the fourth flow guide member 20 with screws 19c.
図４に示すように、第４導流部材２０は、上方に形成された傘部２０ａと、傘部２０ａから下方に延びる板状の板状部２０ｂとを有している。傘部２０ａと板状部２０ｂは、いずれも洗浄槽３の外周面に立設されている。傘部２０ａは、水抜き孔３ｅの中央下方に配置され、水抜き孔３ｅに流れ込んだ水を第３導流部材１９に導くとともに、上方から洗浄槽３と扉材１４との間の空間を覆い隠している。 As shown in FIG. 4, the fourth flow guide member 20 includes an umbrella portion 20 a formed on the upper side and a plate-like plate-like portion 20 b extending downward from the umbrella portion 20 a. Both the umbrella part 20 a and the plate-like part 20 b are erected on the outer peripheral surface of the cleaning tank 3. The umbrella portion 20a is disposed at the lower center of the drain hole 3e, guides the water flowing into the drain hole 3e to the third flow guide member 19, and allows the space between the cleaning tank 3 and the door member 14 from above.

また、第１導流部材１７、第２導流部材１８、第３導流部材１９の板状部１９ａ及び第４導流部材２０の板状部２０ｂの前後方向の幅は、水抜き孔３ｅに流れ込んだ水の流れにおける下流側ほど狭くなるとともに、前側の縁は、水抜き孔３ｅに流れ込んだ水の流れにおける下流側ほど洗浄槽３に近接するように形成されている（図３又は図６参照。）。そのため、第１導流部材１７、第２導流部材１８、第３導流部材１９及び第４導流部材２０に導かれた水は、導流部材の前端部の縁まで流れてきても、その縁に沿って下方に流れ、最後には洗浄槽３の外周面に導かれ、その後、その外周面に沿って下方へ流れる。 In addition, the width in the front-rear direction of the plate-like portion 19a of the first flow guide member 17, the second flow guide member 18, the third flow guide member 19 and the plate-like portion 20b of the fourth flow guide member 20 is the drain hole 3e. The downstream side in the flow of water flowing into the water becomes narrower, and the front edge is formed closer to the washing tank 3 in the downstream side in the flow of water flowing into the drain hole 3e (FIG. 3 or FIG. 6). Therefore, even if the water guided to the first flow guide member 17, the second flow guide member 18, the third flow guide member 19 and the fourth flow guide member 20 flows to the edge of the front end portion of the flow guide member, It flows downward along the edge, is finally guided to the outer peripheral surface of the cleaning tank 3, and then flows downward along the outer peripheral surface.
本実施形態の食器洗浄機１では、水抜き孔３ｅに流れ込んだ水は、まず、第３導流部材１９又は第４導流部材２０によって、第１導流部材１７に導かれる。その後、その水は、第１導流部材１７によって第２導流部材１８に導かれる。最後に、その水は、第２導流部材１８から、内部機器Ｅ１，Ｅ２，Ｅ３等の電子機器が存在しない位置へと導かれる。 In the dishwasher 1 of this embodiment, the water that has flowed into the drain hole 3 e is first guided to the first flow guide member 17 by the third flow guide member 19 or the fourth flow guide member 20. Thereafter, the water is guided to the second flow guide member 18 by the first flow guide member 17. Finally, the water is guided from the second flow guide member 18 to a position where there are no electronic devices such as the internal devices E1, E2, and E3.
そのため、本実施形態の食器洗浄機１では、水抜き孔３ｅに流れ込んだ水によって、内部機器Ｅ１，Ｅ２，Ｅ３に錆や故障が発生することがない。 Therefore, in the dishwasher 1 of this embodiment, rust and failure do not occur in the internal devices E1, E2, and E3 due to the water flowing into the drain hole 3e.
図６に示すように、操作パネル１３の中央部には、ロック機構１６が設けられている。ロック機構１６は、水抜き孔３ｅから上方に向けて突出する爪部１６ａ（係合部）と、爪部１６ａに連設された把持部１６ｂと、爪部１６ａと把持部１６ｂの中心に配置され、爪部１６ａ及び把持部１６ｂを洗浄槽３の左右方向に沿う軸を中心として回転可能とする軸部１６ｃとによって構成されている。 As shown in FIG. 6, a lock mechanism 16 is provided at the center of the operation panel 13. The lock mechanism 16 is disposed at the center of the claw portion 16a (engagement portion) protruding upward from the drain hole 3e, the grip portion 16b connected to the claw portion 16a, and the claw portion 16a and the grip portion 16b. The claw portion 16a and the grip portion 16b are configured by a shaft portion 16c that can rotate around an axis along the left-right direction of the cleaning tank 3.
爪部１６ａは、通常状態（ロック状態。図６において実線で示した状態。）では、筐体２に固定された爪受部２１（被係合部）に係合し、洗浄槽３が筐体２に収納された際に洗浄槽３が引き出されることを制限する。 The claw portion 16a engages with a claw receiving portion 21 (engaged portion) fixed to the housing 2 in a normal state (locked state; a state indicated by a solid line in FIG. 6), and the cleaning tank 3 is a housing. It restrict | limits that the washing tank 3 is drawn out when accommodated in the body 2. FIG.
把持部１６ｂは、扉材１４側に延びており、食器洗浄機１の使用者が操作パネル１３の中心に形成された取手を下方から指を差し込むようにして握った際には、その把持部１６ｂも同時に把持される。把持部１６ｂが把持されると、爪部１６ａは軸部１６ｃを中心として回転して把持部１６ｂと一体的に回転し、水抜き孔３ｅから洗浄槽３と扉材１４との間の空間に収納される。その結果、ロック機構１６はロックが解除された状態（図６において破線で示した状態。）となる。 The gripping part 16b extends to the door member 14 side, and when the user of the dishwasher 1 grips the handle formed at the center of the operation panel 13 by inserting a finger from below, the gripping part 16b is also gripped at the same time. When the gripping portion 16b is gripped, the claw portion 16a rotates about the shaft portion 16c and rotates integrally with the gripping portion 16b, and enters the space between the cleaning tank 3 and the door material 14 from the drain hole 3e. Stored. As a result, the lock mechanism 16 is in an unlocked state (a state indicated by a broken line in FIG. 6).
本実施形態の食器洗浄機１は、水抜き孔３ｅをロック機構１６の一部として構成しているので、水抜き孔３ｅを形成するために装置の大型化や生産コストの増加が生じることはない。 Since the dishwasher 1 of this embodiment comprises the drain hole 3e as a part of the lock mechanism 16, the size of the apparatus and the increase in production cost occur to form the drain hole 3e. Absent.
