Description

本発明は、筐体より洗浄槽を引き出して食器類を収容し、洗浄する食器洗い機に関するものである。 The present invention relates to a dishwasher in which the washing tank is pulled out from the housing to store and wash dishes.

従来、システムキッチンに組み込まれた状態で使用されるビルトイン型の食器洗い機は、前方に開閉可能な扉部を有する洗浄槽を筐体内に固定したものが主流であったが、近年、上方に開口部を有する洗浄槽を筐体より引き出して食器類を収容し、洗浄する食器洗い機が主流となっている（例えば、特許文献１参照）。 Traditionally, built-in dishwashers used in a system kitchen were mainly ones that had a washing tub with an openable door at the front fixed inside the housing, but in recent years, dishwashers that have a washing tub with an opening at the top that can be pulled out from the housing to store and wash dishes have become mainstream (see, for example, Patent Document 1).

また、特許文献１の食器洗い機では、上方に開口部を有し食器類を収容する洗浄槽と、前記洗浄槽を前後方向へ出し入れ自在に支持する筐体と、前記洗浄槽の外に設けられ前記洗浄槽内へ洗剤を投入する洗剤投入口と、前記洗剤投入口と前記洗浄槽とを連通する投入経路を備えたもので、洗浄槽とは独立した箇所に設けた洗剤投入口から洗剤を投入することにより、洗浄槽内に入れられた食器類の大きさや形状に係わらず、確実に洗剤を投入することができるものがあった。 The dishwasher in Patent Document 1 is equipped with a washing tub with an opening at the top for storing dishes, a housing that supports the washing tub so that it can be freely inserted and removed in the front-to-back direction, a detergent inlet that is located outside the washing tub for adding detergent into the washing tub, and an input path that connects the detergent inlet to the washing tub. By adding detergent through the detergent inlet that is located in a location independent of the washing tub, detergent can be reliably added regardless of the size or shape of the dishes placed in the washing tub.

さらに、特許文献２の食器洗い機では、洗浄槽の内壁に洗剤収容容器を着脱自在又は一体的に取り付け、かつこの洗剤収容容器を洗浄槽の内壁に設けた洗浄水の給水口とほぼ同じ高さ又はこれより上方の位置に取り付けた構成により、食器等の洗浄を開始する前に洗剤がこぼれ落ちたり、流出したり固化したりするおそれがなく、食器等を効果的に洗浄することができるものが存在する。 Furthermore, in the dishwasher of Patent Document 2, a detergent container is attached to the inner wall of the washing tub detachably or integrally, and this detergent container is attached at approximately the same height as or higher than the washing water inlet provided on the inner wall of the washing tub, so that dishes, etc. can be washed effectively without the risk of detergent spilling, flowing out, or solidifying before washing of dishes, etc. begins.

しかしながら、このような従来の食器洗い機の構成では、洗剤を上方の開口部から投入するとそのまま洗浄槽に流れ落ちてしまうので、食器洗い機の使用時に都度必要な量の洗剤を使用者が投入しなければならず、洗剤をストックしておくことができない。 However, with this type of conventional dishwasher configuration, when detergent is poured into the dishwasher through the upper opening, it simply flows down into the washing tub, so the user must pour in the required amount of detergent each time they use the dishwasher, and detergent cannot be stocked.

さらに、洗浄槽内に洗剤収容容器を設けると、洗浄槽内の湿気と乾燥を繰り返すことにより、洗剤が固化してしまう場合が起こりうる。また、洗浄槽内に洗剤収容容器を設けると、洗浄槽の容積が小さくなるので食器を載置するスペースが減少してしまう。 Furthermore, if a detergent container is provided inside the washing tub, the detergent may solidify due to repeated exposure to moisture and dryness inside the washing tub. Also, providing a detergent container inside the washing tub reduces the volume of the washing tub, reducing the space available for placing dishes.

本発明は上記従来の課題を解決するもので、洗浄槽外で洗剤をストックして洗剤の固化を極力防ぎ、洗浄槽の容積を確保しつつ、さらに使用者に使い勝手のよい食器洗い機を提供することを目的としている。 The present invention aims to solve the above-mentioned problems of the conventional dishwasher by storing detergent outside the washing tub to prevent the detergent from solidifying as much as possible, while ensuring the capacity of the washing tub and providing a dishwasher that is easy for users to use.

前記従来の課題を解決するために、本発明の食器洗い機は、上方に開口部を有し食器類を収容する洗浄槽と、前記洗浄槽の前面側を覆う扉体と、前記洗浄槽を前後方向へ出し入れ自在に支持する筐体と、前記洗浄槽の外側前方と前記扉体との間に設けられ液体洗剤を溜める洗剤タンクと、前記洗剤タンクと前記洗浄槽とを連通する洗剤吐出経路を備え、洗浄コースや電源オンオフを設定する操作部を更に有し、前記操作部は、前記洗浄槽の外側前方上部であって、前記洗浄槽の外側前方と前記扉体との間に設けられ、前記洗剤タンクは、前記操作部の略下方に収納される。
 In order to solve the above-mentioned problems in the conventional dishwasher, the dishwasher of the present invention comprises a washing tub having an opening at the top for storing tableware, a door body covering the front side of the washing tub, a housing supporting the washing tub so that it can be freely inserted and removed in the front-to-back direction, a detergent tank located between the outside front of the washing tub and the door body for storing liquid detergent, and a detergent discharge path connecting the detergent tank and the washing tub , and further has an operating unit for setting washing courses and turning the power on and off, the operating unit being located on the outside front upper part of the washing tub, between the outside front of the washing tub and the door body, and the detergent tank being stored approximately below the operating unit.

また、前記従来の課題を解決するために、本発明の食器洗い機は、上方に開口部を有し食器類を収容する洗浄槽と、前記洗浄槽を前後方向へ出し入れ自在に支持する筐体と、前記洗浄槽の外側前方に設けられ液体洗剤を溜める洗剤タンクと、前記洗剤タンクと前記洗浄槽とを連通する洗剤吐出経路を備え、前記洗浄槽の外側前方に前記洗剤タンクを収納する洗剤タンク収納部を更に有し、前記洗浄槽を前方向に所定距離以上引き出された状態かつ前記洗剤タンクが前記洗剤タンク収納部に収納された状態で、使用者が目視可能な前記洗剤タンクの側面側に透明部を有し、前記透明部に洗剤量を示す目盛りを有する。 In addition, in order to solve the above-mentioned conventional problems, the dishwasher of the present invention comprises a washing tub having an opening at the top for storing tableware, a housing for supporting the washing tub so that it can be freely inserted and removed in the forward and backward directions, a detergent tank provided on the outside front of the washing tub for storing liquid detergent, and a detergent discharge path connecting the detergent tank and the washing tub, and further has a detergent tank storage section on the outside front of the washing tub for storing the detergent tank, and when the washing tub is pulled out forward a predetermined distance or more and the detergent tank is stored in the detergent tank storage section , it has a transparent section on the side of the detergent tank that is visible to the user, and the transparent section has a scale indicating the amount of detergent.

本発明の食器洗い機は、洗浄槽外で洗剤をストックして洗剤の固化を極力防ぎ、洗浄槽の容積を確保しつつ、使用者が洗剤タンクを容易に着脱することができる。 The dishwasher of the present invention stores detergent outside the washing tub, minimizing the solidification of the detergent, while allowing the user to easily attach and detach the detergent tank while maintaining the capacity of the washing tub.

図２は本発明の実施の形態１における洗剤タンクを収納途中もしくは引出途中の食器洗い機の概略正面図である。また、図３は本発明の実施の形態１における洗剤タンクを収納した状態の食器洗い機の概略正面図である。 Figure 2 is a schematic front view of a dishwasher in the first embodiment of the present invention with the detergent tank in the middle of being stored or pulled out. Also, Figure 3 is a schematic front view of a dishwasher in the first embodiment of the present invention with the detergent tank stored.

図２および図３において、洗剤タンク収納部１４は空洞状となっており、この洗剤タンク収納部１４に洗剤タンク１５が前方（扉体３の正面側）からみて左右方向（側方）へ出し入れ自在に収納される。なお、洗剤タンク１５は平面部２３（または操作部２４、または表示部２５）の略下方に位置する洗剤タンク収納部１４内に配置収納される。なお、図２および図３上では洗剤タンク収納部１４から洗剤タンク１５を右方向に引き出す構成となっているが、洗剤タンク収納部１４および洗剤タンク１５を図２や図３とは左右対称に配置して、洗剤タンク収納部１４から洗剤タンク１５を左方向に引き出す構成としてもよい。 2 and 3, the detergent tank storage section 14 is hollow, and the detergent tank 15 is stored in this detergent tank storage section 14 so that it can be freely inserted and removed in the left-right direction (sideways) when viewed from the front (the front side of the door body 3). The detergent tank 15 is placed and stored in the detergent tank storage section 14 located approximately below the planar section 23 (or the operation section 24, or the display section 25). Although the detergent tank 15 is configured to be pulled out to the right from the detergent tank storage section 14 in FIGS. 2 and 3, the detergent tank storage section 14 and the detergent tank 15 may be placed symmetrically to FIGS. 2 and 3, and the detergent tank 15 may be pulled out to the left from the detergent tank storage section 14.

これにより、洗浄槽１が筐体２に完全に収納された状態では、洗剤タンク１５が目立つことなくシンプルなデザインの食器洗い機を構成することができ、洗浄槽１の外側前方における洗剤タンク１５を収納するスペースを有効活用することができる。 As a result, when the washing tub 1 is completely stored in the housing 2, the detergent tank 15 is not noticeable, making it possible to create a dishwasher with a simple design, and making effective use of the space on the outside front of the washing tub 1 for storing the detergent tank 15.

なお、図１で示すとおり洗剤タンク１５は、洗浄槽１を前方に距離ａ（図１の点線矢印で表示）以上引き出された状態で洗剤タンク収納部１４から左右方向に出し入れ自在に構成されている。距離ａは扉体３と筐体２の合わせ面と洗剤タンク収納部１４の洗浄槽１側の面の最短距離を示す。すなわち距離ａは、洗剤タンク収納部１４全体が筐体２の最前部より前側に引き出されたときの状態を示す。 As shown in Figure 1, the detergent tank 15 is configured so that it can be freely inserted and removed from the detergent tank storage section 14 in the left-right direction when the cleaning tub 1 is pulled out forward by at least distance a (indicated by the dotted arrow in Figure 1). Distance a indicates the shortest distance between the mating surface of the door body 3 and the housing 2 and the surface of the detergent tank storage section 14 on the cleaning tub 1 side. In other words, distance a indicates the state when the entire detergent tank storage section 14 is pulled out forward from the frontmost part of the housing 2.

これにより、洗浄槽１が筐体２に完全に収納された状態では、洗剤タンク１５が目立つことなくシンプルなデザインの食器洗い機を構成することができ、洗浄槽１を前方向に所定距離（距離ａ）以上引き出された状態ではじめて洗剤タンク１５を出し入れすることが
できるので、洗浄槽１の前方における洗剤タンク１５を収納するスペースと、筐体２から洗浄槽１を引き出したときの横方向のスペースとを活用して、洗剤タンク１５を使用者が容易に出し入れすることができる。なお、距離ａは洗剤タンク１５が左右方向に出し入れ可能な距離と規定すれば、それ以上に特に限定するものではない。 As a result, when the washing tub 1 is completely stored in the housing 2, the detergent tank 15 is not noticeable, making it possible to configure a dishwasher with a simple design, and since the detergent tank 15 can be inserted or removed only when the washing tub 1 is pulled out forward a specified distance (distance a) or more, the user can easily insert or remove the detergent tank 15 by utilizing the space for storing the detergent tank 15 in front of the washing tub 1 and the space in the lateral direction when the washing tub 1 is pulled out from the housing 2. Note that distance a is defined as the distance at which the detergent tank 15 can be inserted or removed in the left-right direction, and is not particularly limited beyond that.

また、洗浄槽１の外側前方上部に設けられ、洗浄コースや電源オンオフを設定する操作部２４を有することにより、使用者は例えば洗浄槽１の前方かつ上方から片手で操作部２４を操作しつつ、洗剤タンク１５をもう一方の片手で左右方向へ出し入れすることもできる。 In addition, the cleaning tank 1 has an operating unit 24 that is located at the front upper outside and sets the cleaning course and power on/off, so that the user can operate the operating unit 24 with one hand from the front and above the cleaning tank 1 while using the other hand to move the detergent tank 15 in and out from the left and right.

洗剤タンク１５は、液体洗剤が貯められるボトル状の容器で構成されており、洗剤タンク洗剤吐出口１５ｃと洗剤タンク洗剤吸引経路１５ｄと洗剤入れ蓋部１５ｅで構成されている。 The detergent tank 15 is a bottle-shaped container that stores liquid detergent, and is made up of a detergent tank detergent outlet 15c, a detergent tank detergent suction path 15d, and a detergent container lid 15e.

洗剤タンク洗剤吐出口１５ｃと洗剤タンク洗剤吸引経路１５ｄと洗剤入れ蓋部１５ｅとは一体で構成されており、洗剤タンク１５から着脱可能となっているので、洗剤入れ蓋部１５ｅを洗剤タンク１５から取り外すと、一体で構成されている洗剤タンク洗剤吐出口１５ｃと洗剤タンク洗剤吸引経路１５ｄも洗剤タンク１５から取り外しが可能となっている。なお、洗剤タンク洗剤吸引経路１５ｄの吸引するための先端部は、洗剤タンク１５の底面付近まで延びており、液体洗剤が凡そ無くなるまで吸引することが可能な構成となっている。 The detergent tank detergent outlet 15c, detergent tank detergent suction path 15d, and detergent container lid 15e are integrally formed and can be attached and detached from the detergent tank 15. Therefore, when the detergent container lid 15e is removed from the detergent tank 15, the detergent tank detergent outlet 15c and detergent tank detergent suction path 15d, which are integrally formed, can also be removed from the detergent tank 15. The tip of the detergent tank detergent suction path 15d for suction extends to near the bottom of the detergent tank 15, and is configured to be able to suck in liquid detergent until it is almost completely used up.

使用者は、洗剤タンク１５を洗剤タンク収納部１４から取り外し、洗剤入れ蓋部１５ｅを洗剤タンク１５から取り外すことで液体洗剤を洗剤タンク１５に補充することが可能となっている。 The user can refill the detergent tank 15 with liquid detergent by removing the detergent tank 15 from the detergent tank storage section 14 and removing the detergent dispenser lid section 15e from the detergent tank 15.

これらにより、洗浄槽１の外側で液体洗剤をストックして洗剤の固化を極力防ぎ、洗浄槽１の容積を確保しつつ、使用者が洗剤タンク１５を容易に着脱することができる。 This allows liquid detergent to be stored outside the cleaning tank 1, minimizing the solidification of the detergent, and allows the user to easily attach and detach the detergent tank 15 while maintaining the capacity of the cleaning tank 1.

また、洗剤タンク洗剤吐出口１５ｃは洗剤入れ蓋部１５ｅから側方に凸状に突出した凸部１５ｆを設けている。洗剤タンク収納部１４は、洗剤タンク洗剤吐出口１５ｃの凸部１５ｆが合致する凹部１４ｃを設けており、この凹部１４ｃに凸部１５ｆが合致することで洗剤タンク１５の洗剤タンク収納部１４への収納が完了する。 The detergent tank detergent outlet 15c has a convex portion 15f that protrudes sideways from the detergent container lid portion 15e. The detergent tank storage portion 14 has a concave portion 14c that fits the convex portion 15f of the detergent tank detergent outlet 15c, and the detergent tank 15 is stored in the detergent tank storage portion 14 when the convex portion 15f fits into the concave portion 14c.

この凹部１４ｃと凸部１５ｆが合致することにより、洗剤タンク１５が洗剤タンク収納部１４に収納されることで、洗剤タンク洗剤吐出口１５ｃから洗剤タンク収納部側洗剤吐出経路１４ｂに洗剤を移送するための経路を確保することができ、さらには凸部１５ｆと凹部１４ｃが嵌合することによって、洗剤タンク１５が洗剤タンク収納部１４内に安定して収納することが可能となっている。 By matching the recess 14c and the protrusion 15f, the detergent tank 15 is stored in the detergent tank storage section 14, and a path for transferring detergent from the detergent tank detergent discharge port 15c to the detergent tank storage section side detergent discharge path 14b is secured, and further, by fitting the protrusion 15f and the recess 14c together, the detergent tank 15 can be stored stably within the detergent tank storage section 14.

洗剤タンク収納部１４の凹部１４ｃには、洗剤タンク収納部洗剤吐出口１４ａが設けられ、洗剤タンク収納部洗剤吐出口１４ａには洗剤タンク収納部側洗剤吐出経路１４ｂが配置されている。洗剤タンク収納部側洗剤吐出経路１４ｂの他端には洗剤ポンプ１６が接続され、さらに洗剤ポンプ１６と洗浄槽１の前面に設けられた洗浄槽洗剤吐出口１７との間に洗浄槽側洗剤吐出経路１８が接続されている。すなわち、洗剤ポンプ１６は、洗剤タンク収納部側洗剤吐出経路１４ｂと洗浄槽側洗剤吐出経路１８の間である洗剤投入経路の途中に配置されている。 The detergent tank storage section 14 has a detergent tank storage section detergent outlet 14a in the recess 14c, and a detergent tank storage section side detergent outlet 14b is arranged in the detergent tank storage section detergent outlet 14a. A detergent pump 16 is connected to the other end of the detergent tank storage section side detergent outlet 14b, and a washing tank side detergent outlet 18 is connected between the detergent pump 16 and a washing tank detergent outlet 17 arranged in the front of the washing tank 1. In other words, the detergent pump 16 is arranged in the middle of the detergent input path, which is between the detergent tank storage section side detergent outlet 14b and the washing tank side detergent outlet 18.

これらにより、洗剤タンク１５は液体洗剤を洗剤タンク収納部側洗剤吐出経路１４ｂに吐出する洗剤タンク洗剤吐出口１５ｃを有し、洗剤タンク収納部側洗剤吐出経路１４ｂは
前記洗剤タンク収納部１４と連結され、洗剤タンク洗剤吐出口１５ｃは、洗剤タンク１５が洗剤タンク収納部１４に収納されたとき、洗剤タンク収納部側洗剤吐出経路１４ｂに連結される構成となっている。 As a result, the detergent tank 15 has a detergent tank detergent discharge port 15c that discharges liquid detergent into the detergent tank storage section side detergent discharge path 14b, the detergent tank storage section side detergent discharge path 14b is connected to the detergent tank storage section 14, and the detergent tank detergent discharge port 15c is configured to be connected to the detergent tank storage section side detergent discharge path 14b when the detergent tank 15 is stored in the detergent tank storage section 14.

また、制御装置１９が洗浄槽１の前面下方に配置されており（図１）、循環ポンプ９や排水ポンプ、給水ポンプ（給水弁）、洗剤ポンプ１６の駆動を制御するように構成されている。 The control device 19 is disposed below the front surface of the cleaning tank 1 (Figure 1) and is configured to control the operation of the circulation pump 9, drain pump, water supply pump (water supply valve), and detergent pump 16.

制御装置１９によって洗剤ポンプ１６の駆動回転速度や駆動時間を制御して、食器類８の洗浄時に必要量の液体洗剤を洗剤タンク１５から吸引し、洗剤タンク洗剤吸引経路１５ｄ、洗剤タンク洗剤吐出口１５ｃ、洗剤タンク収納部洗剤吐出口１４ａ、洗剤タンク収納部側洗剤吐出経路１４ｂ、洗剤ポンプ１６、洗浄槽側洗剤吐出経路１８、洗浄槽洗剤吐出口１７を順番に経て、洗剤タンク１５に溜められた液体洗剤を洗浄槽１に移送して供給することができる構成となっている。 The control device 19 controls the drive rotation speed and drive time of the detergent pump 16, so that the required amount of liquid detergent is sucked from the detergent tank 15 when washing the tableware 8, and the liquid detergent stored in the detergent tank 15 is transferred and supplied to the washing tub 1 via the detergent tank detergent suction path 15d, the detergent tank detergent outlet 15c, the detergent tank storage section detergent outlet 14a, the detergent tank storage section side detergent outlet path 14b, the detergent pump 16, the washing tub side detergent outlet path 18, and the washing tub detergent outlet 17 in that order.

図４は本発明の実施の形態１における洗浄槽を筐体から引き出した状態の他の食器洗い機の概略側面図である。 Figure 4 is a schematic side view of another dishwasher in the first embodiment of the present invention with the washing tank pulled out from the housing.

洗剤タンク１５が洗剤タンク収納部１４に収納された状態で、使用者が目視可能な洗剤タンク１５の側面側の少なくとも一部に透明部１５ａを有し、この透明部１５ａに洗剤量を示す目盛り１５ｂを有する。これにより、洗剤タンク１５が洗剤タンク収納部１４に収納された状態であっても、使用者が洗剤量を側方から目視で確認することができるので、液体洗剤の減り具合や補充タイミングを目視により推測することが容易となる。 When the detergent tank 15 is stored in the detergent tank storage section 14, at least a portion of the side of the detergent tank 15 that is visible to the user has a transparent section 15a, and this transparent section 15a has a scale 15b that indicates the amount of detergent. This allows the user to visually check the amount of detergent from the side even when the detergent tank 15 is stored in the detergent tank storage section 14, making it easy to visually estimate how much liquid detergent is running low and when to refill it.

図５は本発明の実施の形態２における洗剤タンクを収納した状態の食器洗い機の概略正面図である。また、図６は本発明の実施の形態２における洗浄槽を筐体から引き出した状態の食器洗い機の概略側面図である。実施の形態１と重複する構成については説明を省略する。 (Embodiment 2)
Fig. 5 is a schematic front view of a dishwasher with a detergent tank stored in the dishwasher according to the second embodiment of the present invention. Fig. 6 is a schematic side view of a dishwasher with a washing tub pulled out from a housing in the second embodiment of the present invention. Descriptions of configurations that overlap with those in the first embodiment will be omitted.

図５において、操作部２４および表示部２５は扉体３の前面上部に配置されており、取手４も実施の形態１の突出した取手とは異なり、扉体３の内方に向けてへこんだ形状の取手４を構成している。 In FIG. 5, the operating unit 24 and the display unit 25 are located at the upper front surface of the door body 3, and the handle 4 is recessed toward the inside of the door body 3, unlike the protruding handle of the first embodiment.

本実施の形態においても、洗浄コースや電源オンオフを設定する操作部２４および表示部２５は、洗浄槽１の外側前方上部に設けられている。これにより、使用者は洗浄槽１の前方かつ上方から操作部２４を操作しつつ、洗剤タンク１５を左右方向へ出し入れできる。なお、操作部２４または表示部２５のいずれかを平面部２３に配置し、他方を扉体３の前面上部に配置してもよいものとする（図６に記載）。 In this embodiment, too, the operation unit 24 for setting the wash course and power on/off and the display unit 25 are provided on the outer front upper part of the washing tub 1. This allows the user to operate the operation unit 24 from the front and above the washing tub 1 while inserting and removing the detergent tank 15 in the left-right direction. Note that either the operation unit 24 or the display unit 25 may be located on the flat surface portion 23, and the other may be located on the front upper part of the door body 3 (as shown in Figure 6).
