In order to solve the conventional problems, a drum-type washing machine according to the present invention includes a rotating tub provided with an opening on the front side, a motor for driving the rotating tub, and washing water in the water tub to the rotating tub. A circulating water channel to be circulated, a pump for feeding the washing water in the water tank to the circulating water channel, at least three nozzles for jetting the washing water fed by the pump into the rotating tank, and the circulation water channel from the A nozzle water channel that guides washing water to the nozzles, and the nozzles are configured such that all the angles between the nozzles around the rotation axis are less than 180 degrees when viewed from the opening surface side of the rotating tub. It is arranged in .

第１の発明は、洗濯水を溜める水槽と、前記水槽内に回転可能に配設され前面側に開口部を設けた回転槽と、前記回転槽を駆動するモータと、前記水槽内の洗濯水を前記回転槽へ循環させる循環水路と、前記水槽内の洗濯水を前記循環水路に送水するポンプと、前記ポンプによって送水される洗濯水を前記回転槽内へ噴出する少なくとも３個のノズルと、前記循環水路から前記ノズルへ洗濯水を導くノズル水路とを備え、前記ノズルは、前記回転槽の開口面側から見て、回転軸心を中心とした各々の前記ノズル間の角度が、全て１８０度未満となるように配設されることにより、洗濯およびすすぎ時に、ポンプにより水槽内に送水する洗濯水が、回転槽内に噴出される範囲を拡大することができるようになり、回転槽内で撹拌されている洗濯物に対して洗濯水がかかる機会が多くでき、回転槽内の洗濯物全体に満遍なく洗濯水を供給し続けることができるため、洗浄性能およびすすぎ性能を向上させることができる。
The first invention is a water tank for storing washing water, a rotating tank that is rotatably disposed in the water tank and has an opening on the front side, a motor that drives the rotating tank, and the washing water in the water tank. A circulating water channel that circulates the rotating tub to the rotating tub, a pump that supplies the washing water in the water tub to the circulating water channel, and at least three nozzles that eject the washing water fed by the pump into the rotating tub. A nozzle water passage that guides washing water from the circulation water passage to the nozzle, and the nozzle has an angle between each of the nozzles with the rotation axis as the center when viewed from the opening surface side of the rotary tub. By being arranged so as to be less than the degree, it becomes possible to expand the range in which the washing water fed into the water tank by the pump is ejected into the rotating tank at the time of washing and rinsing. Laundry being stirred in Opportunity to wash water takes can often for evenly wash water throughout the laundry in the rotary tub can continue to supply, cleaning performance and rinsing performance can be improved with respect.

第２の発明は、特に、第１の発明のノズルは、回転槽の回転軸心の真下方向を避けた位置に設けたことにより、少ない洗濯水で洗浄性能およびすすぎ性能を向上させることができる。一般に、ドラム式洗濯機は、水槽内に溜められた洗濯水の水位が回転槽内の下部に位置するように設定され、回転槽の下部に存在する洗濯物は洗濯水と接触しやすい反面、回転槽内の下部から離れた位置の洗濯物は洗濯水と接触しにくいことから、これを避けた位置にノズルを配置することにより、効率よく洗濯物全体に満遍なく洗濯水を供給し続けることができ、洗浄性能およびすすぎ性能を向上させることができる。In the second aspect of the invention, in particular, the nozzle of the first aspect of the invention can be improved in washing performance and rinsing performance with a small amount of washing water by providing it at a position avoiding the direction directly below the rotation axis of the rotating tub. . In general, the drum-type washing machine is set so that the level of the washing water stored in the water tub is located in the lower part of the rotating tub, while the laundry present in the lower part of the rotating tub is easy to come into contact with the washing water, Since the laundry away from the lower part of the rotating tub is difficult to come into contact with the washing water, the nozzle can be arranged at a position avoiding this so that the washing water can be efficiently and uniformly supplied to the entire laundry. Cleaning performance and rinsing performance can be improved.

第３の発明は、特に、第１または第２の発明のノズルは、回転槽の回転軸心の真下方向を避けた位置に向けて洗濯水を噴出するように設けたことにより、少ない洗濯水で洗浄性能およびすすぎ性能を向上させることができる。一般に、ドラム式洗濯機は、水槽内に溜められた洗濯水の水位が回転槽内の下部に位置するように設定され、回転槽の下部に存在する洗濯物は洗濯水と接触しやすい反面、回転槽内の下部から離れた位置の洗濯物は洗濯水と接触しにくいことから、これを避けた位置に向けて洗濯水を噴出することにより、効率よく洗濯物全体に満遍なく洗濯水を供給し続けることができ、洗浄性能およびすすぎ性能を向上させることができる。According to the third aspect of the invention, in particular, the nozzle of the first or second aspect of the invention provides a small amount of washing water by providing the washing water to be ejected toward a position avoiding the direction directly below the rotation axis of the rotating tub. The cleaning performance and rinsing performance can be improved. In general, the drum-type washing machine is set so that the level of the washing water stored in the water tub is located in the lower part of the rotating tub, while the laundry present in the lower part of the rotating tub is easy to come into contact with the washing water, Since the laundry away from the lower part of the rotating tub is difficult to come into contact with the washing water, the washing water is efficiently sprayed to the entire laundry by spraying the washing water toward the position avoiding this. The cleaning performance and the rinsing performance can be improved.

第４の発明は、特に、第１〜第３のいずれか１つの発明のノズル水路は、開口部の周縁部の外側に略円状に設けたことにより、複数のノズルを環状に配設することができ、回転槽内で撹拌されている洗濯物に対して洗濯水を上下左右方向から満遍なく供給することができ、洗浄性能およびすすぎ性能を向上させることができる。In the fourth invention, in particular, the nozzle water channel of any one of the first to third inventions is provided in a substantially circular shape outside the peripheral edge of the opening, thereby arranging a plurality of nozzles in an annular shape. The washing water can be uniformly supplied from the top, bottom, left and right directions to the laundry being stirred in the rotating tub, and the washing performance and the rinsing performance can be improved.
