Then, a water supply valve (not shown) is operated, and water is supplied into the sub drum 2 through the water supply pipe 30, and the supplied water wets the delicate clothing that has been thrown in, while the inclined surface top opening 7b or the inclined surface bottom. When the water flows from the opening 7d into the rotary drum 1 and reaches a predetermined water level, the water supply stops and the washing process starts, and the rotary drum 1 rotates left and right and the washing proceeds.

回転ドラム１が左右回転を始めると、洗濯水１３が回転ドラム１内壁に設けられたバッフル３により揚水９となって掻き揚げられ、バッフル３が上方に行った時にバッフル３の通水孔３３よりサブドラム２へ向かって噴水され、その水がサブドラム２の頂部に設けられた頂部開口部７ｃや傾斜面５に設けられた傾斜面頂部開口部７ｂ、傾斜面底部開口部７ｄからサブドラム２内部へ供給され、サブドラム２内に設けたサブドラムバッフル４による作用も加味されて、洗浄が促進される。   When the rotating drum 1 starts to rotate left and right, the washing water 13 is pumped up by the baffle 3 provided on the inner wall of the rotating drum 1 to be pumped up 9, and when the baffle 3 moves upward, the baffle 3 passes through the water passage hole 33. Water is sprayed toward the sub drum 2, and the water is supplied into the sub drum 2 from the top opening 7c provided on the top of the sub drum 2, the inclined top opening 7b provided on the inclined surface 5, and the inclined bottom opening 7d. Further, the action of the sub drum baffle 4 provided in the sub drum 2 is taken into consideration, and the cleaning is promoted.

この時、傾斜面５の最頂部側には、外周側へ凸となるようにリング状に凸状リブ部１０が形成されているために、通水孔３３からの水が効率良く傾斜面頂部開口部７ｂ、傾斜面底部開口部７ｄからサブドラム２内部へ供給される。   At this time, since the convex rib portion 10 is formed in a ring shape so as to protrude toward the outer peripheral side on the topmost side of the inclined surface 5, the water from the water passage hole 33 is efficiently inclined to the top of the inclined surface. It is supplied into the sub drum 2 from the opening 7b and the inclined surface bottom opening 7d.

そして、サブドラム２内部へ供給されデリケートな衣類を濡らし浸透した水は、傾斜面頂部開口部７ｂ、傾斜面底部開口部７ｄから回転ドラム１内へ流れていき、回転ドラム１の回転により循環される。   Then, the water that has been supplied to the inside of the sub-drum 2 and has wetted and permeated the delicate clothes flows into the rotating drum 1 from the inclined surface top opening 7b and the inclined surface bottom opening 7d, and is circulated by the rotation of the rotating drum 1. .

また、洗い行程の所定の期間には、ポンプ１２が駆動して、上述のように、回転ドラム１内の洗濯水１３は、サブドラム２の底部開口部７ａを介してサブドラム２内に射出され、内部に投入されたデリケート衣類を濡らした後、傾斜面頂部開口部７ｂおよび傾斜面底部開口部７ｄから回転ドラム１内に流れ、また循環することにより、更に洗浄が促進される。   Further, during a predetermined period of the washing process, the pump 12 is driven, and the washing water 13 in the rotary drum 1 is injected into the sub drum 2 through the bottom opening 7a of the sub drum 2, as described above. After the delicate garment put in the inside is wetted, it flows into the rotating drum 1 from the inclined surface top opening 7b and the inclined surface bottom opening 7d and circulates, thereby further promoting the cleaning.

なお、回転ドラム１にサブドラム２を取り付けて内部にデリケートな衣類を投入して洗うと同時に、必要に応じて、回転ドラム１内に一般的な衣類を投入して洗うこともできるし、サブドラム２は着脱自在であるためにサブドラム２を取り外して、一般的な衣類を洗うこともできる。   The sub drum 2 is attached to the rotating drum 1 and delicate clothes are put in and washed at the same time. At the same time, general clothes can be put in the rotating drum 1 and washed as needed. Since it is detachable, the sub-drum 2 can be removed to wash general clothing.

以上のように、本実施の形態１においては、回転ドラム１の背面側内底部に、回転ドラム１と同一の回転軸８上に分け洗い用のサブドラム２を配設する構成とすることにより、デリケートな衣類を、少ない時間、少ない水量で、布傷みを発生させることなく、洗浄性能を確保して洗うことができる。   As described above, in the first embodiment, the sub-drum 2 for separate washing is disposed on the same rotary shaft 8 as the rotary drum 1 at the inner bottom portion on the back side of the rotary drum 1. Delicate clothing can be washed in a small amount of time and with a small amount of water, without causing fabric damage, while ensuring cleaning performance.

また、サブドラム２は、前面である頂部に開閉自在の蓋体１４を設け、この蓋体１４側が径小の略円錐台形状に形成されている。この頂部の蓋体１４に頂部開口部７ｃ、底部に底部開口部７ａ、頂部と底部をつなぐ傾斜面５の頂部側に傾斜面頂部開口部７ｂ、傾斜面５の底部側に傾斜面底部開口部７ｄの複数の開口部７を形成する構成とすることにより、洗い行程において、回転ドラム１が回転してバッフル３により掻き揚げられた洗濯水が、バッフル３の通水孔３３からサブドラム２の開口部７を介してサブドラム２内に供給され続けるので、洗浄性能を向上させることができる。   The sub drum 2 is provided with a lid 14 that can be opened and closed at the top, which is the front surface, and the lid 14 is formed in a substantially truncated cone shape with a small diameter. The top lid 14 has a top opening 7 c, a bottom opening 7 a at the bottom, an inclined surface top opening 7 b on the top side of the inclined surface 5 connecting the top and the bottom, and an inclined surface bottom opening on the bottom side of the inclined surface 5. By adopting a configuration in which a plurality of openings 7d are formed, the washing water swung up by the baffle 3 by the rotation of the rotary drum 1 in the washing process is opened from the water passage hole 33 of the baffle 3 to the opening of the sub drum 2. Since it is continuously supplied into the sub drum 2 via the section 7, the cleaning performance can be improved.

また、サブドラム２は、頂部と底部をつなぐ傾斜面５の最頂部側に、外周側へ凸となるようにリング状に凸状リブ部１０を形成する構成とすることにより、洗い行程において、回転ドラム１が回転してバッフル３により掻き揚げられた洗濯水が、バッフル３の通水孔３３からより効率良く、特にサブドラム２の傾斜面５の開口部７を介してサブドラム２内に供給され続けるので、洗浄性能を向上させることができる。   In addition, the sub drum 2 is configured to form a convex rib portion 10 in a ring shape so as to be convex toward the outer peripheral side on the topmost side of the inclined surface 5 connecting the top portion and the bottom portion. The washing water swung up by the baffle 3 as the drum 1 rotates is more efficiently supplied from the water passage hole 33 of the baffle 3, in particular, into the sub drum 2 through the opening 7 of the inclined surface 5 of the sub drum 2. Therefore, the cleaning performance can be improved.

また、給水管３０は、一端を給水弁と他端を水槽３２の背面側と接続され、給水時にはサブドラム２の底部開口部７ａを介してサブドラム２内に給水する構成とすることにより、サブドラム２内のデリケート衣類を早く濡らすことができるので、洗浄性能を向上させることができる。   In addition, the water supply pipe 30 has one end connected to the water supply valve and the other end connected to the back side of the water tank 32, and supplies water into the sub drum 2 through the bottom opening 7 a of the sub drum 2 during water supply. Since the delicate clothes inside can be wetted quickly, the cleaning performance can be improved.

また、接続管３７は、一端をポンプ１２と他端を水槽３２の背面側と接続され、ポンプ１２駆動時において、水槽３２内の洗濯水をサブドラム２の底部開口部７ａを介してサブドラム２内に噴出して循環する構成とすることにより、サブドラム２内のデリケート衣類に洗濯液を早く浸透させることができるので、洗浄性能を向上させることができる。   The connecting pipe 37 has one end connected to the pump 12 and the other end connected to the back side of the water tank 32. When the pump 12 is driven, the washing water in the water tank 32 is passed through the bottom opening 7a of the sub drum 2 into the sub drum 2. Since the washing liquid can be quickly infiltrated into the delicate clothes in the sub-drum 2, the washing performance can be improved.
