Description

【０００１】
【発明の属する技術分野】
本発明は洗濯時やすすぎ時に多量の水を注ぐ給水装置を有する洗濯機に関するものである。
【０００２】
【従来の技術】
従来、洗濯機は図６に示すような構成が一般的であった。以下、その構成について説明する。
【０００３】
図に示すように、水受け槽１は、底部にパルセータ２を回転自在に配設した洗濯兼脱水槽３を内包し、吊り棒４によって外枠５に吊り下げている。外枠５の上部に上部外装体６を装着し、上部外装体６の略中央部に布投入口７を形成し、蓋８で覆っている。また、上部外装体６の後部に電磁給水弁９と注水装置１０を設けている。注水装置１０は、洗剤投入蓋１１を回転自在に設け、上部外装体６に装着しており、流出口１２より洗濯兼脱水槽３内に注水するものである。
【０００４】
上記構成において、洗濯行程では、洗剤を洗濯兼脱水槽３に直接投入した場合は、洗剤投入蓋１１の下端が流出口１２となり、この流出口１２より水を流出させる。注水装置１０の洗剤投入蓋１１内に洗剤を投入した場合は、洗濯時に給水を始めると、水は流出口１２より注がれ、洗剤を水の勢いで水と一緒に洗濯兼脱水槽３に注水する。所定の水位に達するとパルセータ２を駆動して洗濯する。洗濯が終了し高濃度の洗濯液を排水した後、すすぎ行程でも、水は流出口１２から洗剤投入蓋１１を介して洗濯兼脱水槽３に注がれ、水受け槽１内に水を溜めて衣類に付いている洗剤成分をすすぎ水の中で拡散し希釈を行っている。
【０００５】
【発明が解決しようとする課題】
このような従来の構成では、注水装置１０は、後部から前部に向けて多量の水が注水され、給水時に、前方に勢いよく流水するため、多量の水の飛び散りが発生する。ここで、注水量を少なくする方法が考えられるが、洗濯時の注水時間が長くなり、洗濯時間の遅延を招き使用者に不快感を与えるという問題を有していた。そこで、洗濯時とすすぎ時に水を多量に注ぐための流出口１２を装備することが必要である。
【０００６】
本発明は上記課題を解決するもので、洗濯時に多量の水を注水可能にするとともに、洗濯時やすすぎ時に水の飛び散りがなく給水できるようにすることを目的としている。
【０００７】
【課題を解決するための手段】
本発明は上記目的を達成するために、外枠と、前記外枠の上部に装着した上部外装体と、前記上部外装体の略中央部に形成した布投入口と、水道水を流入するための電磁給水弁と、前記上部外装体の後部に設けられ洗濯槽内に注水する注水装置とを備え、前記注水装置は、前面が開口し底面部が前方に向けて傾斜する収納箱と、前記収納箱の後部に設けられ前記電磁給水弁と連通する流入口と、前記収納箱の前面開口部と当接し前記上部外装体と一体に形成された前面壁と、前記収納箱の底面部の前方側に一体に形成され先端に流出口を有する略凹部と、前記収納箱の前面開口部の下部に回動可能に取り付けられた洗剤投入蓋とから構成され、前記前面壁の下端は、前記底面部より下方に位置するとともに、前記流出口より上方に位置し、前記洗剤投入蓋は、その閉時においては、前記前面壁に引っ掛けられた状態でその下端が前記底面部より下方に位置し、その開時においては、その上面である洗剤投入部の下端が前記流出口の下側に当接する構成としたものである。
【０００８】
これにより、洗濯時に多量の水を注水可能にするとともに、洗剤投入蓋の閉時には、洗剤投入蓋の下端が注水装置の底面部より下方にあるため、洗剤投入蓋により流れを押さえることができ、洗濯時やすすぎ時に水の飛び散りがなく給水することができる。
【０００９】
【発明の実施の形態】
本発明の請求項１に記載の発明は、外枠と、前記外枠の上部に装着した上部外装体と、前記上部外装体の略中央部に形成した布投入口と、水道水を流入するための電磁給水弁と、前記上部外装体の後部に設けられ洗濯槽内に注水する注水装置とを備え、前記注水装置は、前面が開口し底面部が前方に向けて傾斜する収納箱と、前記収納箱の後部に設けられ前記電磁給水弁と連通する流入口と、前記収納箱の前面開口部と当接し前記上部外装体と一体に形成された前面壁と、前記収納箱の底面部の前方側に一体に形成され先端に流出口を有する略凹部と、前記収納箱の前面開口部の下部に回動可能に取り付けられた洗剤投入蓋とから構成され、前記前面壁の下端は、前記底面部より下方に位置するとともに、前記流出口より上方に位置し、前記洗剤投入蓋は、その閉時においては、前記前面壁に引っ掛けられた状態でその下端が前記底面部より下方に位置し、その開時においては、その上面である洗剤投入部の下端が前記流出口の下側に当接する構成としたものであり、注水装置の後部から前方向に向けて多量の水が流れても、洗剤投入蓋の閉時には、洗剤投入蓋の下端が注水装置の底面部より下方にあるため、洗剤投入蓋により流れを押さえることができ、水が前方向に勢いよく流出するのを防止でき、水の飛び散りを防止することができ、注水装置の後部から前方向に向けて流れる水が前面壁により前方向への勢いが下方向に向かい、水の勢いを弱めることができ、略凹部により下方向に向かった水が前方向へと流れを変えることができ、水の飛び散りを防止することができる。また、洗剤投入蓋の開放時には、前面壁と略凹部により勢いが弱められた状態で洗剤投入蓋を通過するため、洗剤投入蓋がジャンプ台にならずに水の飛び散りを防止することができる。
【００１０】
請求項２に記載の発明は、上記請求項１に記載の発明において、収納箱の底面部の中央部に凹溝部を設け、前記凹溝部の両端部には、並列リブを設けたものであり、水道水圧が低く、給水量が少なくても、美観を損ねることのない流水パターンで注水することができる。
【００１１】
請求項３に記載の発明は、上記請求項１または２に記載の発明において、流入口は、収納箱の後部側壁に設けられ、前記収納箱の底面部には、前記流入口の反対側の側壁側に単数または複数個の並列リブを設けたものであり、洗剤投入蓋の開放時に流水パタ−ンが一方方向に片寄らずに、美観を損ねることのない流水パターンで注水することができるとともに、洗剤投入蓋の洗剤の解け残りを防止することができる。
【００１２】
【実施例】
以下、本発明の実施例について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【００１３】
（実施例１）
図１に示すように、注水装置１３は、洗剤投入蓋１４を開閉可能に設け、流出口１５より洗濯兼脱水槽（洗濯槽）３内に注水するもので、図２および図３に示すように、前面開口の収納箱１６を設け、収納箱１６の後部側壁に流入口１７を形成し、収納箱１６の底面部１８は前方に向けて傾斜面とし、上部外装体６に装着し、上部外装体６の後部上面に設けた電磁給水弁９と流入口１７を流入ホ−ス１９で連通させている。収納箱１６の前面開口部は上部外装体６に一体形成されている注水装置１３の前面壁２０と当接されるとともに、下方のみ非当接部とし流出口１５を形成している。
【００１４】
洗剤投入蓋１４は、収納箱１６の前面開口下部に設けた略円筒形凸部２１と洗剤投入蓋１４に設けた取り付けＵ字部２２とにより回動可能に取り付け、その回動支点と逆方向の洗剤投入蓋１４には、前面壁２０に引っ掛け可能とする爪部２３を設け、洗剤投入蓋１４を開閉可能としている。ここで、洗剤投入蓋１４は、閉時に洗剤投入蓋１４の下端が底面部１８より下方に位置するような構成としている。
【００１５】
上記構成において、洗濯時やすすぎ行程では、水は、水道より給水ホ−ス（図示せず）を介して電磁給水弁９に入り、流入ホ−ス１９と流入口１７を通り収納箱１６に至り、流出口１５より洗濯兼脱水槽３に注水する。
【００１６】
ここで、水道水圧（流量）が高く後部から前方向に向けて多量の水が流れても、洗剤投入蓋１４の閉時には、洗剤投入蓋１４の下端が収納箱１６の底面部１８より下方にあるため、洗剤投入蓋１４が障壁となり、水の流れを押さえて、前方向に勢いよく流出するのを防止することができ、多量の水の飛び散りを防止することができる。
【００１７】
（実施例２）
図２に示すように、注水装置１３を装着した上部外装体６に注水装置１３の前面壁２０を一体に形成し、この前面壁２０の下端は、注水装置１３の底面部１８より下方になる位置とし、略凹部２４を底面部１８と一体に形成し、略凹部２４の先端に流出口１５を形成している。この略凹部２４の先端は、前面壁２０の下端より下部に位置する構成とし、流出口１５は前方向への開放状態になり、前方向への流出が可能となっている。他の構成は上記実施例１と同じである。
【００１８】
上記構成において、水道水圧（流量）が高い場合、流入口１７と収納箱１６を通った水は、前面壁２０により前方向への勢いが下方向に向かい、この前面壁２０により乱流を形成するため、勢いも弱めることができ、略凹部２４により下方向に向かった水が前方向へと流れを変え、洗濯兼脱水槽３に注がれる。
【００１９】
ここで、洗剤投入蓋１４の閉時には、水道水圧（流量）が高くても、前面壁２０により勢いが押さえられた状態で下方向に向かった流れとなり、洗濯兼脱水槽３に注がれるため、水の飛び散りを防止することができる。
【００２０】
また、洗剤投入蓋１４の開放時に、洗剤を洗剤投入蓋１４に乗せる場合、その洗剤は水により押し流されるとともに、水に解けて洗濯兼脱水槽３に投入されるが、前述のように、水道水圧（流量）が高くても前面壁２０と略凹部２４により勢いが弱められた状態で洗剤投入蓋１４を通過するため、洗剤投入蓋１４がジャンプ台にならずに洗剤および水の飛び散りを防止することができる。
【００２１】
なお、洗剤投入蓋１４の開放時には、図２の一点鎖線で示すように、略凹部２４を形成している底面部１８に洗剤投入蓋１４が当接するため、必ず水が洗剤投入部２５を通過可能であり、洗剤投入蓋１４と略凹部２４の流出口１５が略連結状態となっているため、下への水漏れが防止でき、水道水圧（流量）が逆に低い場合でも、必ず洗剤を押し流すとともに溶解することができ、洗濯兼脱水槽３に注ぐことができる。
【００２２】
（実施例３）
図３および図４に示すように、注水装置１３の収納箱１６は、後部側面に流入口１７を設け、流入口１７近傍の断面積は小とし、流出口１５を形成している前面に向けて断面積を大きくする略ラッパ状を形成し、底面部１８には、狭い断面積状態の底面の幅と略同一幅の凹溝部２６を中央部に設けるとともに、凹溝部２６の両端部に並列リブ２７を設けている。他の構成は上記実施例１および実施例２と同じである。
【００２３】
上記構成において、水道水圧（流量）が低い場合は、給水量も少なく、流出口１５の全域に流れることはなく、流水パタ−ンが使用者の美観を損ねないように中央近傍に集中するようにするため、流入口１７を通過した水が流出口１５に到達するまでに底面部１８を蛇行しないように、凹溝部２６と並列リブ２７で形成した流水通路２８を通るようにすることで、流水パタ−ンをよくすることが可能となる。
【００２４】
（実施例４）
図３から図５に示すように、収納箱１６の底面部１８に、流入口１７と反対側に複数個（図では単数）の並列リブ２９を設け、並列リブ２９の高さは流水通路２８を形成している並列リブ２７の高さより同等以上としている。他の構成は上記実施例１から実施例３と同じである。
【００２５】
上記構成において、水道水圧（流量）が高い場合は、給水量が多いため、水は流入口１７と反対側の壁方向へと向かおうとするが、並列リブ２９により抵抗または跳ね返りとなり、流入口１７側の壁まで水が広がるため、流水パタ−ンが一方向に片寄らずに流出口１５の広域にわたるパタ−ンとなり、使用者の美観を損ねることのない注水が可能となる。
【００２６】
また、洗剤投入蓋１４の開放時に洗剤を投入した場合でも、流水パタ−ンが広域であり、洗剤投入蓋１４の全面に乗せた洗剤を容易に押し流すことができ、洗剤の解け残りを防止することができる。
【００２７】

[0012]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. In addition, the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0013]
Example 1
As shown in FIG. 1, the water injection device 13 is provided with a detergent charging lid 14 so that it can be opened and closed, and injects water into the washing and dewatering tub (washing tub) 3 from the outlet 15, as shown in FIGS. 2 and 3. A storage box 16 having a front opening is provided, an inflow port 17 is formed in the rear side wall of the storage box 16, and a bottom surface 18 of the storage box 16 is inclined toward the front, and is attached to the upper exterior body 6. An electromagnetic water supply valve 9 and an inflow port 17 provided on the upper surface of the rear portion of the exterior body 6 are communicated with an inflow hose 19. The front opening of the storage box 16 is in contact with the front wall 20 of the water injection device 13 formed integrally with the upper exterior body 6, and the non-contact portion is formed only in the lower portion to form the outflow port 15.
[0014]
The detergent charging lid 14 is rotatably mounted by a substantially cylindrical convex portion 21 provided at the lower front opening of the storage box 16 and a mounting U-shaped portion 22 provided on the detergent charging lid 14, and is opposite to the rotation fulcrum. The detergent charging lid 14 is provided with a claw portion 23 that can be hooked on the front wall 20 so that the detergent charging lid 14 can be opened and closed. Here, the detergent charging lid 14 is configured such that the lower end of the detergent charging lid 14 is positioned below the bottom surface portion 18 when closed.
[0015]
In the above configuration, in the rinsing process during washing, water enters the electromagnetic water supply valve 9 from a water supply via a water supply hose (not shown), passes through the inflow hose 19 and the inflow port 17 to the storage box 16. The water is poured into the washing / dehydrating tub 3 from the outlet 15.
[0016]
Here, even if the tap water pressure (flow rate) is high and a large amount of water flows from the rear toward the front, when the detergent charging lid 14 is closed, the lower end of the detergent charging lid 14 is below the bottom surface 18 of the storage box 16. For this reason, the detergent charging lid 14 becomes a barrier, and it is possible to prevent the water from flowing out in a forward direction while suppressing the flow of water, and to prevent a large amount of water from splashing.
[0017]
(Example 2)
As shown in FIG. 2, the front wall 20 of the water injection device 13 is formed integrally with the upper exterior body 6 to which the water injection device 13 is attached, and the lower end of the front wall 20 is below the bottom surface portion 18 of the water injection device 13. The substantially recessed portion 24 is formed integrally with the bottom surface portion 18, and the outflow port 15 is formed at the tip of the substantially recessed portion 24. The front end of the substantially concave portion 24 is located below the lower end of the front wall 20, and the outlet 15 is open in the forward direction and can flow out in the forward direction. Other configurations are the same as those of the first embodiment.
[0018]
In the above configuration, when the tap water pressure (flow rate) is high, the water that has passed through the inlet 17 and the storage box 16 is moved forward by the front wall 20 to form a turbulent flow. Therefore, the momentum can also be weakened, and the water directed downward by the substantially concave portion 24 changes the flow forward and is poured into the washing and dewatering tub 3.
[0019]
Here, when the detergent charging lid 14 is closed, even if the tap water pressure (flow rate) is high, the flow is directed downward while the momentum is suppressed by the front wall 20 and is poured into the washing and dewatering tub 3. Water splashing can be prevented.
[0020]
In addition, when the detergent is put on the detergent charging lid 14 when the detergent charging lid 14 is opened, the detergent is washed away by water and dissolved in water and thrown into the washing and dehydrating tub 3. Even if the water pressure (flow rate) is high, the detergent charging lid 14 passes through the detergent wall 14 in a state where the force is weakened by the front wall 20 and the substantially concave portion 24. Therefore, the detergent charging lid 14 does not become a jump stand and prevents splashing of detergent and water. can do.
[0021]
When the detergent charging lid 14 is opened, the detergent charging lid 14 comes into contact with the bottom surface portion 18 forming the substantially concave portion 24 as shown by a one-dot chain line in FIG. This is possible because the detergent inlet lid 14 and the outlet 15 of the substantially recessed portion 24 are in a substantially connected state, so that it is possible to prevent water leakage downward, and even when the tap water pressure (flow rate) is low, the detergent must be used. It can be melted as it is swept away and poured into the washing and dewatering tub 3.
[0022]
Example 3
As shown in FIGS. 3 and 4, the storage box 16 of the water injection device 13 is provided with an inflow port 17 on the rear side surface, a small cross-sectional area in the vicinity of the inflow port 17, and toward the front surface forming the outflow port 15. A substantially trumpet shape is formed to increase the cross-sectional area, and the bottom surface portion 18 is provided with a concave groove portion 26 having a width substantially the same as the width of the bottom surface in a narrow cross-sectional area state in parallel with both end portions of the concave groove portion 26. Ribs 27 are provided. Other configurations are the same as those of the first and second embodiments.
[0023]
In the above configuration, when the tap water pressure (flow rate) is low, the amount of water supply is small and does not flow in the entire area of the outlet 15, so that the flowing water pattern is concentrated near the center so as not to impair the user's aesthetics. In order to prevent the water passing through the inflow port 17 from passing through the bottom surface 18 before reaching the outflow port 15, the water flows through the flowing water passage 28 formed by the concave groove portion 26 and the parallel rib 27. It is possible to improve the running water pattern.
