a and a first filter member 10 arranged coaxially with a gap in the outer cylinder.
Is composed of a large lattice-shaped porous support (core) integrally formed of polypropylene resin and a first filter 10a that is releasably wound around the porous support 18 in a doubly double manner. Has been done. And the first filter 10
In particular, in FIG. 5, a is a belt-like shape formed by welding a polyester resin felt with an antibacterial agent-containing acrylic resin, has a contact surface portion 19 on the inner side of the rear end, and manually touches a portion facing in a double-wrapped state. It has a detachable contact surface portion 20. On the other hand, 21 is the second eye which is rougher than the first filter 10a.
The filter is composed of an open-cell body made of polyurethane resin, 22 is a front case for accommodating the second filter 21, and its bottom wall 23 closes the front end opening of the porous support 18 and surrounds the bottom wall 23. The through hole 24 is open to face the gap between the first filter 10a and the outer cylinder 11a of the central cylindrical portion 11. In the free length, the axial length of the first filter 10a is set to be slightly larger than the dimension (for example, 80 mm) between the rear wall 25 and the bottom wall 23 (for example, 82 mm).
mm), so that both walls 23 and 25 and the first filter 10a are brought into close contact with each other, and water that has become contaminated due to a gap is generated in the first filter 10a.
It is designed so that it does not leak without going through a.

7, and the hose 4 is connected to the reduced diameter portion (hose connecting portion) 12a of the outlet. In addition, 28 is a vinyl resin tube, and 29 is a vinyl chloride resin coil fused around the tube 28 to give the hose 4 flexibility. Next, the operation of the suction structure 3 having the above configuration will be described.

きる。First, when the suction structure 3 is submerged in the bath water (used water) W in the bathtub as a fluid and the self-contained pump 2 is operated, even if a predetermined priming water exists in the self-contained pump 2. The bath water W can be supplied from the suction structure 3 through the hose 4 (into the washing tub 5) by the self-contained pump 2 (usually supplied when tap water is supplied).

る。At this time, the water sucked from the through hole 17 of the suction end member 13 passes through the second filter 21 to remove relatively large dirt (hair etc.), and passes through the through hole 24 to the first filter 10a. Small dirt is removed from the outer peripheral surface through the first filter 10a. Here, the through hole 17 is formed large because the amount of water flowing is large near the through hole 24.

フィルタの役目をしている。The removal of the dirt by the first filter 10a is performed by the three-dimensional filtration with a large surface area, and therefore the amount can be reduced. The water from which the dirt has been removed through the first filter 10a in this way is led out to the hose 4 through the porous support 18 from the rear end opening 25a of the rear wall 25 through the third filter 27. Here, the third filter 27 has substantially the same eye size as that of the second filter 21, and even if the first filter 10a or the first filter 10a and the second filter 2 are forgotten to be attached. , It serves as a safety filter by preventing dirty water from being supplied to the washing machine 5 without passing through a filter.

The front case 22 and the porous support 18 are extracted from the body 3 to remove the porous support 18
The first filter 10a wound around the periphery of the
The contact between the contact surface 9 and the surface-to-be-contacted portion 20 is released and removed to remove dirt.

Since it is reversed, the water in the suction structure 3 does not drip, and since the weight 26 is located below the suction structure 3, the outlet member 1 incorporating the weight 26 therein.
2 is in close contact with the side wall 15, whereby vibration (resonance) can be prevented even when the washing machine 5 is operated.

First, in FIG. 7, the control unit 32 includes a microcomputer that controls the washing machine 5, and based on the key input signal from the key input unit 33, the detection result of the water level sensor 34, and the like, the washing / dehydrating tub and the rotary vanes (illustrated). The drive motor 35 for driving (omitted), the water supply valve 36 directly connected to the water supply, the self-contained pump 2 and the electromagnetic drainage valve 37 are drive-controlled.

をすすぎ水として洗濯槽に供給する。In FIG. 8, it is considered that there is almost no priming of the self-contained pump 2 at the time of the first washing, so the water supply valve 36 directly connected to the water supply is turned on for about 15 seconds to supply tap water as priming, and then self-supplied. The formula pump 2 is turned on to supply bath water as washing water. At the next step of rinsing (trial rinsing, water rinsing, dehydration rinsing), the priming of the self-contained pump 2 is usually almost left at the time of washing. It is turned on for about 5 seconds to inject tap water as supplementary priming water, and then the self-contained pump 2 is turned on to supply bath water as rinse water to the washing tub.

Tap water can be saved and the rinsing time can be shortened.

が容易になり、全体構成を小形にできる。According to the present invention, a double cylindrical body including another cylindrical filter member and an outer cylinder is incorporated in a suction structure having a disk-shaped filter member built therein, and a fluid is disk-shaped. After passing through the first filter member, the third filter member is structured three-dimensionally so that the dirt can be filtered from the outer periphery of the cylinder by passing the fluid from the outer periphery of the cylinder, thereby ensuring a large filtration area and thereby finely filtering the fluid. Can remove dirt,
In addition, maintenance such as monitoring of filter dirt and cleaning becomes easy, and the overall structure can be made compact.
