ジ３１止めすることにより取付けられている。 A radial back blade 15 is integrally molded on the back side of the rotor blade 2, and a pump chamber 18 is formed on the back side of the rotor blade by the washing tub substrate 4, the washing tub bottom recess 16, and the peripheral wall 17 of the recess 16. There is. A plurality of suction ports 19 to the pump chamber 18 are bored in the washing tub board 4,
The discharge port 20 of the pump chamber 18 is formed by opening the peripheral wall 17 in a V-shape as shown in FIG. A groove 21 is formed from the bottom of the washing tub 1 to the upper end of the side wall in communication with the discharge port 20, and a water channel cover 22 is fitted into the groove 21 to form a water supply channel 23. The upper part of the water channel cover 22 has locking protrusions 24 and 25 protruding from both sides thereof, which are fitted into locking ribs 26 and 27 formed on the front side of both side faces of the groove 21, so that the upper part of the waterway cover 22 projects from the flat surface of the waterway cover. installed protrusion 2
8 to the side wall of the washing tub with screws 29, and the lower part of the water channel cover 22 is attached by fixing a tongue piece 30 integrally extended from the lower end to the bottom of the washing tub with screws 31. .

る。 A discharge duct 32 that serves as a discharge port of the water supply channel 23 and directs liquid coming out of the water channel inward is integrally formed on the upper end of the water channel cover 22. Discharge duct 32
is a concave portion 33 formed by recessing the inner surface of the balance ring 3.
located within. A bag-shaped lint filter 34 is removably attached facing the tip of the discharge duct 32, and the liquid discharged from the discharge duct 32 is returned into the washing tub 1 through the lint filter 34. The lint filter 34 is constructed by engaging the lower end locking piece 36 of the frame body 35 with its mouth edge attached to the locking part 37 provided integrally with the balance ring 3, and engaging the elastic claw protruding from the upper end of the frame body 35. 38 is attached to the tip of a ceiling plate 39 that protrudes from the upper surface of the balance ring so as to cover the recess 33.

槽１内へ戻る。 In this configuration, when the rotary blade 2 is rotated after water is supplied to the washing tub 1 up to the specified water level H, the pump action of the back blade 15 causes suction to be drawn into the pump chamber 18 through the suction port 19 as shown by the arrow in FIG. The liquid between the washing tub 1 and the outer tub 12 (which eventually becomes the liquid inside the washing tub) is sent to the water supply channel 23, discharged from the discharge duct 32 toward the lint filter 34, and returned to the washing tub 1. .

この際液中に含まれた糸屑はリントフイルター

水流にて洗濯槽内の水流を乱し、洗浄効果を向上
させるものである。 At this time, the lint contained in the liquid is captured by a lint filter, and the water flow discharged from the discharge duct 32 disturbs the water flow in the washing tub, thereby improving the cleaning effect.

ンプ室側端を第４図の如く折曲４０して補強して
いた。 By the way, the water channel cover 22 has conventionally been reinforced by bending 40 the end of its upper surface on the pump chamber side as shown in FIG.

なエネルギーが必要であつた。 However, if the water channel cover 22 is reinforced in this way, the bent portion 40 acts like a weir for the water flow toward the water supply channel, causing turbulent flow at this portion, which prevents the water from flowing smoothly from the pump chamber 18 to the water supply channel 23. In other words, the liquid stops flowing, which increases the loss, and in order to discharge a sufficient amount of liquid from the discharge duct into the washing tub, the pump output of the back blade must be increased, which requires extra energy. Ta.

本考案はかかる点に鑑みてなされたもので、第

きる。 The present invention has been made in view of this point, and as shown in FIG. 1, the pump chamber side end 41 of the upper surface of the water channel cover 22 is folded back into the water supply channel 23. When the water channel cover 22 is made of synthetic resin, the third
This can be easily done by splitting the molds 42 and 43 as shown in the figure into left and right sides.

で、従来のものに比べて強くすることができる等
種々の効果を奏するものである。 Since the present invention has such a configuration, the liquid flows smoothly from the pump chamber 18 to the water supply channel 23 without causing turbulence at the end of the water supply channel 23 on the side of the pump chamber 18 as in the conventional case, and the pump output of the back blade is A sufficient amount of liquid can be discharged from the discharge duct 32 into the washing tub without increasing the size. Waterway cover 22
Since the strength of this part is doubled by folding it back, it has various effects such as being stronger than conventional ones.
