システムキッチンに設置されるビルトイン型の食器洗浄機は、システムキッチンに組み込まれた筐体から洗浄槽を前方に引き出して食器を出し入れするようになっている。この洗浄槽は、箱型で上面が開放されており、内部に食器かごを備えている。洗浄槽に食器を入れるときには、引き出された状態の洗浄槽の上方から食器かごに食器を載置する。 The built-in type dishwasher installed in the system kitchen draws out the washing tub forward from a housing built in the system kitchen and puts in and out the tableware. This washing tank is box-shaped and has an open top surface and includes a tableware basket inside. When putting tableware into the washing tub, the tableware is placed on the tableware basket from above the drawn out washing tub.
従来、この種の洗浄槽に設けられる食器かごは上下2段に構成され、下段の食器かごには大皿、小皿、椀等の比較的大きい食器が載置され、上段の食器かごにはコップや湯飲み類といった比較的小さい食器が載置されるようになっている(例えば特許文献1参照)。そして、上段の食器かごは、下段の食器かごへの食器を載置するときに邪魔にならないように、起立方向に回動することができるように設けられている。 Conventionally, a tableware basket provided in this type of washing tank is configured in two upper and lower stages, a relatively large tableware such as a large plate, a small plate or a bowl is placed in the lower tableware basket, and a cup or A relatively small tableware such as a cup of tea is placed (for example, see Patent Document 1). The upper table basket is provided so as to be able to rotate in the standing direction so as not to get in the way when the tableware is placed in the lower table basket.
しかし、上記従来の食器かごは、上段の食器かごと下段の食器かごとが連結された状態で構成されており、下段の食器かごには、上段の食器かごを回動自在に支持するための構成が必要となる。更に、下段の食器かごが上段の食器かごに載置した食器の荷重を支える強度を有する必要もある。このため、食器かごの構成が極めて複雑となる不都合がある。 However, the conventional tableware basket is configured in such a manner that the upper tableware basket and the lower tableware basket are connected to each other, and the lower tableware basket is configured to rotatably support the upper tableware basket. Configuration is required. Furthermore, it is necessary for the lower tableware basket to have the strength to support the load of the tableware placed on the upper tableware basket. For this reason, there is an inconvenience that the configuration of the tableware basket becomes extremely complicated.
上記の点に鑑み、本発明は、食器かごの構造を極めて簡単とし、食器かごへの荷重負荷も軽減できる食器洗浄機を提供することを目的とする。 In view of the above points, an object of the present invention is to provide a dishwasher that can greatly simplify the structure of a tableware basket and reduce the load on the tableware basket.

It is characterized by being formed lower than the uppermost part of the protrusion .
本発明によれば、食器かごを回動自在に軸支するための軸受部を、洗浄槽の周壁内面に一体に設けたことにより、食器かごは、軸受部に軸支させる部分を備えるだけでよく、回動自在となる食器かごの構造を極めて簡単とすることができると共に、食器かごへの荷重負荷も軽減できる。 According to the present invention, since the bearing portion for pivotally supporting the tableware basket is integrally provided on the inner surface of the peripheral wall of the cleaning tank, the tableware basket has only a portion for pivotally supporting the bearing portion. The structure of the tableware basket that can be freely rotated can be made extremely simple, and the load on the tableware basket can be reduced.
また、洗浄槽の軸受部が凹部を備え、食器かごは、その回動軸が軸受部の凹部に装着されることにより洗浄槽内に取り付けられる。これにより、軸受部の構成を極めて簡単として食器かごを回動自在とすることができるだけでなく、凹部による食器かごの回動軸の支持を解除して食器かごを洗浄槽から容易に取り外すことができる。 Moreover, the bearing part of a washing tank is provided with a recessed part, and the tableware basket is attached in a washing tank by the rotation axis | shaft being mounted in the recessed part of a bearing part. As a result, the structure of the bearing portion can be made extremely simple and the tableware basket can be rotated freely, and the support of the rotation axis of the tableware basket by the recess can be released and the tableware basket can be easily removed from the washing tub. it can.
また、食器かごの回動軸が前記傾斜面により軸受部の凹部に向かって確実に案内されるので、食器かごの回動軸を軸受部の凹部に装着する作業を容易として且つ確実に装着することができる。 In addition, since the rotation axis of the tableware basket is reliably guided toward the concave portion of the bearing portion by the inclined surface, the operation of mounting the rotation axis of the tableware basket in the concave portion of the bearing portion is easily and reliably mounted. be able to.
本発明の実施形態を図面に基づいて説明する。図1に示す本実施形態の食器洗浄機1は、システムキッチンに組み込に設置されるビルトイン式のものであり、食器洗浄機1の筐体2には、前方に引出し自在な洗浄槽3が収容されている。 Embodiments of the present invention will be described with reference to the drawings. The dishwasher 1 of this embodiment shown in FIG. 1 is a built-in type installed in a system kitchen, and a housing 2 of the dishwasher 1 has a washing tank 3 that can be pulled out forward. Contained.
洗浄槽3の底部側には、洗浄水を噴出する洗浄ノズル4が設けられており、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, and a drying duct for introducing drying air for drying dishes in the cleaning tank 3 on the back side of the cleaning tank 3. 5 and a drying fan 6 are provided.
更に、洗浄槽3の底部には、洗浄槽3内に残菜フィルタ7を介して連通する洗浄水の溜り部8が設けられている。洗浄槽3の底部下側には、溜り部8に連通する洗浄・排水ポンプ9が設置されている。洗浄・排水ポンプ9は、正転させたときに洗浄ノズル4に洗浄水を供給し、逆転させたときに洗浄槽3からの排水を行う。 Furthermore, at the bottom of the cleaning tank 3, there is provided a cleaning water reservoir 8 that communicates with the inside of the cleaning tank 3 via a leftover filter 7. A cleaning / drainage pump 9 communicating with the reservoir 8 is installed below the bottom of the cleaning tank 3. The cleaning / drainage pump 9 supplies cleaning water to the cleaning nozzle 4 when rotated forward, and drains the cleaning tank 3 when rotated reversely.
洗浄槽3の内部には、上部食器かご10と下部食器かご11とが取り付けられている。下部食器かご11は、大皿、小皿、中鉢、椀等の比較的大型の食器Wを支持し、上部食器かご10は、コップや湯飲み等の比較的小径で底の深い食器Wを支持する。なお、上部食器かご10が本発明における食器かごに相当する。上部食器かご10の詳細な構成については後述する。 An upper table basket 10 and a lower table basket 11 are attached to the inside of the washing tub 3. The lower tableware basket 11 supports a relatively large tableware W such as a large plate, a small plate, a medium bowl, and a bowl, and the upper tableware basket 10 supports a tableware W having a relatively small diameter and a deep bottom such as a cup or a cup of water. The upper tableware basket 10 corresponds to the tableware basket in the present invention. The detailed configuration of the upper tableware basket 10 will be described later.
前記洗浄ノズル4は、洗浄槽3の下部食器かご11の下側に配設された水平方向に長手の下ノズル12と、下ノズル12の長手方向中央部に立設されたセンターノズル13とにより構成されている。 The washing nozzle 4 includes a lower nozzle 12 that is horizontally disposed below the lower dish basket 11 of the washing tub 3 and a center nozzle 13 that is erected at the center in the longitudinal direction of the lower nozzle 12. It is configured.
下ノズル12は、その長手方向中央部で鉛直軸線回りに旋回しつつ下部食器かご11に向けて洗浄水を噴出する。下ノズル12は、洗浄・排水ポンプ9から供給される洗浄水の噴出反力によって旋回するようになっている。 The lower nozzle 12 spouts washing water toward the lower table basket 11 while turning around the vertical axis at the center in the longitudinal direction. The lower nozzle 12 is turned by the reaction force of the washing water supplied from the washing / drainage pump 9.
センターノズル13は下ノズル12と一体に回転する下半部13aと、この下半部13aに上下動自在に挿設された上半部13b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13は下ノズル12と共に旋回しつつ水圧によって上半部13b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13の下半部13aの上端部(上半部13bとの境界位置)に形成されている噴出口と、上半部13bに形成されている噴出口との両方から放射状に洗浄水が噴出される。 The center nozzle 13 includes a lower half 13a that rotates integrally with the lower nozzle 12, and an upper half 13b that is inserted in the lower half 13a so as to be movable up and down. When cleaning water is supplied from the cleaning / drainage pump 9, the center nozzle 13 rotates with the lower nozzle 12, and the upper half 13 b extends upward by water pressure. Then, cleaning is performed radially from both the jet outlet formed at the upper end of the lower half 13a of the center nozzle 13 (the boundary position with the upper half 13b) and the jet formed at the upper half 13b. Water spouts out.
上部食器かご10は、図2に示すように、樹脂コーティングされた金属製線材によって形成された基枠14と、基枠14に固定された合成樹脂製の食器支持部材15とで構成されており、図3に示すように、洗浄槽3の後方半部に取り付けられている。 As shown in FIG. 2, the upper table basket 10 is composed of a base frame 14 formed of a resin-coated metal wire, and a synthetic resin tableware support member 15 fixed to the base frame 14. As shown in FIG. 3, it is attached to the rear half of the cleaning tank 3.
食器支持部材15は、図2に示すように、湾曲する2列の食器載置部15a,15bを備えている。食器載置部15a,15bの夫々には、複数の食器Wが2列に並べて載置される。なお、図示省略したが、食器載置部15a,15bが湾曲する形状であるため、これに沿って配列された食器Wは平面視扇状に並べられる。 As shown in FIG. 2, the tableware support member 15 includes two rows of tableware placement portions 15 a and 15 b that are curved. A plurality of tablewares W are arranged in two rows on each of the tableware placement units 15a and 15b. In addition, although illustration was abbreviate | omitted, since the tableware mounting parts 15a and 15b are the shapes which curve, the tableware W arranged along this is arranged in fan shape in planar view.
基枠14は、図2及び図3に示すように、後端側で左右方向に延出する回動軸部16と、前方に向かって平行に延出する一対の前方延出部17とを備えている。 2 and 3, the base frame 14 includes a rotating shaft portion 16 that extends in the left-right direction on the rear end side, and a pair of front extending portions 17 that extend in parallel toward the front. I have.
回動軸部16は、図4に示すように、洗浄槽3の互いに対向する左右の側壁内面の後壁面寄りの位置に一体に形成された軸受部18に支持される。軸受部18は、洗浄槽3の側壁内面から突出する突出部19と、突出部19に形成された凹部20とを備えている。凹部20は、上端が開放され下端が閉塞された溝状に形成されている。また、軸受部18の突出部19の上面には、凹部20に向って下降する方向に傾斜する傾斜面21が形成されている。 As shown in FIG. 4, the rotating shaft portion 16 is supported by a bearing portion 18 that is integrally formed at a position near the rear wall surface of the right and left side walls of the cleaning tank 3 that face each other. The bearing 18 includes a protrusion 19 that protrudes from the inner surface of the side wall of the cleaning tank 3 and a recess 20 that is formed in the protrusion 19. The recess 20 is formed in a groove shape having an upper end opened and a lower end closed. In addition, an inclined surface 21 is formed on the upper surface of the protruding portion 19 of the bearing portion 18 so as to be inclined toward the concave portion 20.
上部食器かご10は、回動軸部16が軸受部18の凹部20の下端に着座した状態で軸支されることで、起立方向に回動自在となる。また、凹部20の上端が開放されていることにより、回動軸部16を凹部20から容易に脱出させることができ、上部食器かご10の洗浄槽3への付け外しを容易に行うことができる。 The upper table basket 10 is pivotally supported in a state in which the rotation shaft portion 16 is seated on the lower end of the recess 20 of the bearing portion 18, thereby being rotatable in the standing direction. Moreover, since the upper end of the recessed part 20 is open | released, the rotating shaft part 16 can be easily escaped from the recessed part 20, and the attachment or detachment to the washing tank 3 of the upper tableware basket 10 can be performed easily. .
更に、回動軸部16は、軸受部18の突出部19に形成されている傾斜面21により凹部20に入る方向に案内されるので、上部食器かご10の洗浄槽3への取り付けを円滑に行うことができる。 Further, the rotating shaft portion 16 is guided in the direction of entering the concave portion 20 by the inclined surface 21 formed on the protruding portion 19 of the bearing portion 18, so that the upper table basket 10 can be easily attached to the washing tub 3. It can be carried out.
また、前方延出部17は、図5に示すように、洗浄槽3の左右の側壁内面に一体に形成された当接段部22の上端に当接支持される。前方延出部17が当接段部22の上端に当接したとき、上部食器かご10は水平姿勢となる。 Further, as shown in FIG. 5, the front extending portion 17 is abutted and supported by the upper ends of the abutting step portions 22 formed integrally with the left and right side wall inner surfaces of the cleaning tank 3. When the front extension part 17 contacts the upper end of the contact step part 22, the upper tableware basket 10 is in a horizontal posture.
このように、洗浄槽3の側壁内面に、上部食器かご10の回動軸部16を軸支する軸受部18を設けたことにより、上部食器かご10を、例えば下部食器かご11に回動自在に支持することなく構造簡単に回動自在とすることができる。 Thus, by providing the bearing portion 18 that pivotally supports the rotation shaft portion 16 of the upper table basket 10 on the inner surface of the side wall of the washing tub 3, the upper table basket 10 can be freely rotated to the lower table basket 11, for example. It is possible to make the structure easy to rotate without supporting it.
上部食器かご10を回動させて起立姿勢にすることにより、図6に示すように、上部食器かご10の下方に位置する下部食器かご11の上方が開放されるので、下部食器かご11への食器Wの載置作業が容易となる。しかも、下部食器かご11と独立して上部食器かご10を洗浄槽3から取り外すことができるので、上部食器かご10を取り外して下部食器かご11の上方空間を広くすることができる。よって、例えば下部食器かご11に鍋等の比較的大型の被洗浄物を載置させるときにも、上部食器かご10が邪魔になることがなく、洗浄対象物の自由度も高くなる。 By rotating the upper tableware basket 10 to the upright posture, as shown in FIG. 6, the upper side of the lower tableware basket 11 located below the upper tableware basket 10 is opened. Placement work of the tableware W becomes easy. Moreover, since the upper table basket 10 can be detached from the washing tub 3 independently of the lower table basket 11, the upper table basket 10 can be removed to widen the upper space of the lower table basket 11. Therefore, for example, when a relatively large object to be cleaned such as a pan is placed on the lower tableware basket 11, the upper tableware basket 10 does not get in the way, and the degree of freedom of the object to be cleaned increases.
ところで、上部食器かご10を、その回動によって起立させると、図6に示すように、上部食器かご10の先端側が洗浄槽3の上縁よりも高い位置にはみ出した状態となる。上部食器かご10の起立状態が維持されると、前方に引出されている洗浄槽3を筐体2に戻すときに、洗浄槽3の上部にはみ出した上部食器かご10が筐体2と干渉するおそれがある。 By the way, when the upper tableware basket 10 is raised by its rotation, the tip side of the upper tableware basket 10 protrudes to a position higher than the upper edge of the washing tub 3 as shown in FIG. If the standing state of the upper tableware basket 10 is maintained, the upper tableware basket 10 that protrudes from the upper part of the washing tub 3 interferes with the case 2 when the washing tub 3 drawn forward is returned to the case 2. There is a fear.
そこで、本実施形態においては、上部食器かご10を起立方向に起立させたとき、上部食器かご10の後端が洗浄槽3の後壁内面3aに当接してこれ以上起立させることができないようになっている。洗浄槽3の後壁内面3aは、本発明の規制部に相当する。即ち、図6に示すように、規制部として機能する洗浄槽3の後壁内面3aは、上部食器かご10の重心gが軸受部18による回動支点(本実施形態では回動軸部16の中心)を通る鉛直線xを超えない位置で上部食器かご10の回動を規制する。 Therefore, in the present embodiment, when the upper tableware basket 10 is erected in the standing direction, the rear end of the upper tableware basket 10 abuts against the rear wall inner surface 3a of the washing tub 3 so that it cannot be raised any further. It has become. The rear wall inner surface 3a of the cleaning tank 3 corresponds to a restricting portion of the present invention. That is, as shown in FIG. 6, the rear wall inner surface 3 a of the cleaning tank 3 that functions as a restricting portion is configured such that the center of gravity g of the upper tableware basket 10 is a rotation fulcrum by the bearing portion 18 (in this embodiment, the rotation shaft portion 16. The rotation of the upper tableware basket 10 is restricted at a position not exceeding the vertical line x passing through the center).
これにより、使用者が、上部食器かご10の回動軸部16より遠い先端を持ち上げるようにして起立方向に回動させると、上部食器かご10の後端部が洗浄槽3の後壁内面3aに当接し、上部食器かご10の回動が規制された状態となる。このとき、上部食器かご10の重心gは、軸受部18による回動支点を通る鉛直線xよりも前方に位置する。そして、使用者が上部食器かご10から手を離すと、上部食器かご10は起立状態を維持できずに自重で水平姿勢に戻る。その後、水平姿勢の上部食器かご10には、図7に示すように、食器Wを載置することができる。 As a result, when the user rotates the upper table basket 10 in the upright direction by lifting the tip far from the rotation shaft 16 of the upper table basket 10, the rear end portion of the upper table basket 10 is the rear wall inner surface 3 a of the washing tub 3. And the rotation of the upper tableware basket 10 is restricted. At this time, the center of gravity g of the upper tableware basket 10 is located in front of the vertical line x passing through the rotation fulcrum by the bearing portion 18. When the user releases his hand from the upper tableware basket 10, the upper tableware basket 10 returns to the horizontal posture with its own weight without being able to maintain the standing state. Thereafter, the tableware W can be placed on the upper tableware basket 10 in a horizontal posture as shown in FIG.
このように、洗浄槽3の後壁内面3aが上記の状態で上部食器かご10を規制することにより、前方に引出されている洗浄槽3を筐体2に戻すときに、それに先立ち上部食器かご10が自重で水平姿勢に戻り、上部食器かご10と筐体2との干渉を防止することができる。また、上部食器かご10は自重で起立姿勢から水平姿勢になるので、常に食器Wが載置できる状態となり、起立姿勢の上部食器かご10を水平姿勢に回動させる煩わしい操作を不要とすることができる。 Thus, when the rear wall inner surface 3a of the washing tub 3 regulates the upper tableware basket 10 in the above-described state, when the washing tub 3 drawn forward is returned to the housing 2, the upper tableware basket prior to that is returned. 10 returns to a horizontal posture by its own weight, and interference between the upper tableware basket 10 and the housing 2 can be prevented. Further, since the upper tableware basket 10 changes from the standing posture to the horizontal posture by its own weight, the tableware W can always be placed, and the troublesome operation of rotating the upper tableware basket 10 in the standing posture to the horizontal posture is unnecessary. it can.
なお、本実施形態においては、洗浄槽3の後壁内面3aを平坦な状態で規制部としているので、極めて構造簡単である。これは、洗浄槽3の後壁内面3aから軸受部18までの距離や上部食器かご10の後端部形状により可能となるものである。一方、これ以外に、図示しないが、洗浄槽3の後壁内面3aから上部食器かご10の後端部に向って突出する突起を規制部として形成し、起立させた上部食器かご10の所定部分を突起に当接させることで上部食器かご10の回動を規制してもよい。 In the present embodiment, the inner surface 3a of the rear wall of the cleaning tank 3 is used as a regulating portion in a flat state, so that the structure is extremely simple. This is made possible by the distance from the rear wall inner surface 3 a of the cleaning tank 3 to the bearing portion 18 and the shape of the rear end portion of the upper tableware basket 10. On the other hand, other than this, although not shown, a predetermined part of the upper tableware basket 10 is formed by forming a protrusion protruding from the rear wall inner surface 3a of the washing tub 3 toward the rear end of the upper tableware basket 10 as a restricting portion. Rotation of the upper tableware basket 10 may be regulated by bringing the upper table into contact with the projection.
