Is formed.

図３は、本発明の実施の形態におけるドラム式洗濯機の注水経路の正面図であり水槽カバー６の外面の略球面状部１５に設けられた開口１６の正面を示す。この開口１６の形状は正面から見て略一文字形状をなし、その両側部１６ａの上下幅は、中央部１６ｂの上下幅より広く形成されている。   FIG. 3 is a front view of the water injection path of the drum type washing machine in the embodiment of the present invention, and shows the front of the opening 16 provided in the substantially spherical portion 15 on the outer surface of the water tank cover 6. The shape of the opening 16 is substantially a single character when viewed from the front, and the vertical width of both side portions 16a is wider than the vertical width of the central portion 16b.

上記構成によるドラム式洗濯機の動作を説明する。   The operation of the drum type washing machine having the above configuration will be described.

窓部７を開いてドラム４内に洗濯物及び洗剤を投入してドラム式洗濯機１の運転を開始すると、給水弁１１に通電され動作し、水槽３内には注水管路１２と注水経路２２から所定時間に所定量の注水がなされ、モータ１０によりドラム４が回転駆動されて洗濯行程が行われる。この時、ドラム４の回転により、ドラム４内に収容された洗濯物はドラム４の内周壁に設けられた撹拌突起９によって回転方向に持ち上げられ、持ち上げられた適当な高さ位置から落下する撹拌動作が繰り返されると同時に、温水洗濯コースを選択した場合は、加熱装置１４により所定の温度になるまで水槽３内の水は加熱され、この加熱された高温の温水により窓部７の内面側の内窓部７ａも加熱される。   When the window 7 is opened and laundry and detergent are put into the drum 4 and the operation of the drum-type washing machine 1 is started, the water supply valve 11 is energized to operate, and the water tank 3 has a water injection pipe 12 and a water injection path. A predetermined amount of water is injected from 22 at a predetermined time, and the drum 4 is driven to rotate by the motor 10 to perform the washing process. At this time, the laundry housed in the drum 4 is lifted in the rotating direction by the stirring protrusion 9 provided on the inner peripheral wall of the drum 4 by the rotation of the drum 4 and falls from the lifted appropriate height position. When the hot water washing course is selected at the same time as the operation is repeated, the water in the water tub 3 is heated by the heating device 14 until a predetermined temperature is reached, and the heated hot water on the inner surface side of the window portion 7 is heated. The inner window portion 7a is also heated.

所定の洗濯時間の後、汚れた洗濯液は排水管路１３から排出されるが、その際窓部７を操作した場合に人体が触れても安全な温度以下になるように給水弁１１を動作させ、水を注水経路２２から水槽カバー６の略球面状部１５の開口１６に導き、その開口１６で略扇状に広がらせ窓部７の内面側全体を濡らす作用が行われ、窓部７の内窓部７ａを冷却する構成である。この時、一時停止操作を行って、すぐに窓部７を開けることができるのみならず、窓部７の内窓部７ａ温度は安全な温度以下に下がっているため、腕等が接触しても火傷等の危険性は無くなる。   After a predetermined washing time, the dirty washing liquid is discharged from the drainage pipe 13, but when the window portion 7 is operated at that time, the water supply valve 11 is operated so as to be below a safe temperature even if a human body touches it. Then, water is guided from the water injection path 22 to the opening 16 of the substantially spherical portion 15 of the water tank cover 6, and spreads in a substantially fan shape through the opening 16 to wet the entire inner surface side of the window portion 7. It is the structure which cools the inner window part 7a. At this time, not only can the window portion 7 be opened immediately by performing a pause operation, but the temperature of the inner window portion 7a of the window portion 7 has dropped below a safe temperature, so that the arm etc. There is no risk of burns.

次に、ドラム４を高速回転させる脱水動作により洗濯物に含まれた洗濯液を遠心脱水し、その後、水槽３内に再び注水管路１２と注水経路２２から注水してすすぎ行程が実施され、最後に、脱水行程が実施される。   Next, the washing liquid contained in the laundry is centrifugally dehydrated by a dehydrating operation of rotating the drum 4 at a high speed, and then a rinsing process is performed by again injecting water into the water tank 3 from the water injection pipe 12 and the water injection path 22. Finally, a dehydration process is performed.

また、前記の開口１６の両側部１６ａの上下幅は、中央部１６ｂの上下幅より広く形成されているので、水は両側部１６ａ部に多く流れ、その結果、扇状の吐出形状が形成でき、窓部７の内窓部７ａ全体を満遍なく濡らすことができる。   In addition, since the vertical width of both side portions 16a of the opening 16 is formed wider than the vertical width of the central portion 16b, a large amount of water flows to both side portions 16a, and as a result, a fan-like discharge shape can be formed. The entire inner window portion 7a of the window portion 7 can be wetted evenly.

図４は、本発明の実施の形態におけるドラム式洗濯機の注水経路の要部断面図であり、開口１６の形成される略球面状部１５は、略半球状とすることにより、開口１６の開口角度αを最も大きくすることができるので、その結果、更に広い範囲に広がる扇状の吐出形状が形成でき、窓部７の内窓部７ａ全体を満遍なく濡らすことができる。   FIG. 4 is a cross-sectional view of the main part of the water injection path of the drum type washing machine in the embodiment of the present invention. The substantially spherical portion 15 in which the opening 16 is formed has a substantially hemispherical shape. Since the opening angle α can be maximized, as a result, a fan-like discharge shape extending over a wider range can be formed, and the entire inner window portion 7a of the window portion 7 can be evenly wetted.

また、窓部７の内窓部７ａにかかる水は、扇状ではなくても、内窓部７ａにかかる位置で内窓部７ａ全体を濡らすことができれば、同様の効果が得られる。   Even if the water applied to the inner window 7a of the window 7 is not fan-shaped, the same effect can be obtained as long as the entire inner window 7a can be wetted at the position applied to the inner window 7a.

また、注水経路２２の途中が、ホース部材１９と、パイプ部材２１で形成されているのでシール構成が簡素化され、しかもその組み立て作業性や補修時のサービス作業が容易になる。即ち、袋状部材１７と水槽カバー６の略円筒状の突出部１８の内側の内部開口部２０と連通するパイプ部材２１を、可撓性と柔軟性を有する例えばエラストマー等の材料で形成することにより、両端嵌合部のシール性を十分確保することができ、内窓部７ａに吐出する開口１６に至るまでの経路途中での水漏れ防止ができるので衣類の濡れ性を十分に確保できる。また、上記パイプ部材２１は、嵌合部に可撓性と柔軟性があるため、水槽カバー６の内方より袋状部材１７と突出部１８の内部開口部２０に容易に装着が可能であり、組立作業性も優れている。   Moreover, since the middle of the water injection path 22 is formed by the hose member 19 and the pipe member 21, the seal configuration is simplified, and the assembly workability and service work at the time of repair are facilitated. That is, the pipe member 21 that communicates with the inner opening 20 inside the bag-shaped member 17 and the substantially cylindrical protrusion 18 of the water tank cover 6 is formed of a material such as an elastomer having flexibility and flexibility. As a result, it is possible to sufficiently secure the sealing performance of the fitting portions at both ends, and to prevent water leakage in the course of the route leading to the opening 16 that discharges to the inner window portion 7a, thereby sufficiently ensuring the wettability of the clothing. In addition, since the pipe member 21 has flexibility and flexibility in the fitting portion, it can be easily attached to the bag-like member 17 and the internal opening 20 of the protruding portion 18 from the inside of the water tank cover 6. Also, assembly workability is excellent.

以上のように、本発明にかかるドラム式洗濯機は、温水洗濯コースでの洗濯時に、洗濯途中や終了時に窓部を開ける行為をする際に、窓部を開ける前に窓部の内面側全体に水が扇状に広がってかかるので、窓部全体の温度を低減することができるので、温水洗濯コースを有する家庭用、業務用洗濯機、洗浄装置等に有用である。   As described above, the drum-type washing machine according to the present invention, when washing in the hot water washing course, when performing the act of opening the window part during or at the end of washing, before opening the window part, the entire inner surface side of the window part Since the water spreads in a fan shape, the temperature of the entire window portion can be reduced, which is useful for households, commercial washing machines, washing devices and the like having a hot water washing course.
