The present invention relates to a suction structure of a self-contained pump for washing machines, and more particularly, to a suction structure used at the tip of the suction hose of the self-contained pump for washing machines.

Bath water, that is, the water remaining in the bath after use is commonly used for rinsing water of the washing machine as part of water saving, and in particular, a washing machine has been proposed in which a self-contained pump is built into the washing machine so that the bath water is automatically supplied from the tub to the washing machine.

In addition, the suction end of the suction hose of the self-contained pump is provided with an inlet port at one terminal part and an outlet port that contacts the suction hose at the other terminal part, and a suction structure (sieve) is inserted between the inlet port and the outlet port. This removes dirt from the bath water so that it does not get into the washing machine.

By the way, the bath water often contains a large amount of small time (floating solids, for example small time, bath residues, oil components, etc.).

And the filter mentioned above is not able to be removed until such a small time.

So, if you try to remove these tiny spots with a filter with a fine scale, the filter will be clogged frequently, which will require frequent cleaning of the filter.

One of the main objectives of the present invention is to provide a suction structure of a self-contained pump for a washing machine which can remove small dirts as described above, monitors the dirt of the filter, and is easy to repair such as cleaning.

The present invention is a double cylindrical body consisting of a cylindrical first filter member and an outer cylinder arranged on the same axis at intervals on the outside of the first filter member, and a second filter on one terminal of the double cylindrical body. A suction terminal member connected through the member and having an opening, and an outlet member connected to the other terminal of the double cylindrical body, and the fluid is spaced between the first filter member and the external cylinder through the second filter member. A suction structure of a self-contained pump for a washing machine, which is configured to be sucked and then guided from the inside to the outlet member through the first filter member.

That is, the present invention combines another cylindrical filter member and a double cylinder of the outer cylinder to the suction structure containing the disk-shaped filter member, the body of the cylindrical filter member after passing the fluid through the disk filter member Three-dimensional configuration to filter the time by passing the fluid through the outside of the filter to secure a large filtration area, thereby removing the small time of the fluid, and also to monitor the dirt of the filter, to facilitate the maintenance, such as cleaning, etc. It can be miniaturized.

Here, the first filter member as another cylindrical filter member is composed of a cylindrical multi-hole support (core) and a first filter wound around the body of the multi-hole support so as to be released. By allowing it to pass through, the filterability by the three-dimensional filtration structure with a large surface area can be improved further, and maintenance work, such as monitoring and cleaning of the dirt of a 1st filter, can be made easy.

EXAMPLE

Hereinafter, the present invention will be described in detail according to the accompanying drawings.

In addition, this invention is not limited to this Example.

1 is a schematic illustration showing a state in which the bath water is supplied from the bathtub to the washing machine using the suction structure of the self-contained pump for washing machine of the present invention.

In FIG. 1, the bath water as a fluid, that is, the remainder W of the bathtub 1, has a water level in the case up to the inlet of the self-contained pump 2 (always, the inlet of the pump. It is supplied to the washing machine 5 of the washing machine (3) via the hose (4) from the suction structure (3) by a pump capable of executing.

6 is a pump case incorporating a self-contained pump 2, 7 is a check valve for supplying the rest of the tub W into the pump case 6, 2a is a pump motor, and 2b is a fan of the pump. .

2 is a side view of the suction structure, with a top view at the top and a bottom view at the bottom.

3 is a cross-sectional view taken along line AA ′ of FIG. 2, FIG. 4 is a side view of the filter, and FIG. 5 is a cross-sectional view taken along line B-B ′ of FIG. 4.

First, in FIG. 2, the case body 9 of the suction structure 3 incorporates a cylindrical first filter 10a (see FIG. 3) and observes the soiled state of the first filter 10a from outside. The central cylindrical portion 11 and the outlet member 12 and the suction terminal member 13 are detachably mounted on the upper and lower ends of the central cylindrical portion 11, respectively, and 14 is a suction structure. When not using (3), it is a hook member which hangs the suction structure 3 to the hole 16 of the main body case side wall 15 of the washing machine 5. (refer FIG. 1).

In addition, 17 is a large number of passage holes of the suction terminal member 13, the hole in the center is small (small diameter), the periphery of the hole is formed (large diameter), respectively, to correspond to the distribution of the flow rate of water after suction, which will be described later. I'm making it.

3 to 5, the central cylindrical portion 11 is an outer cylinder 11a formed of a transparent synthetic resin, for example, an AS resin, and a first filter member 10 disposed coaxially with an interval in the outer cylinder. The first filter member 10 has a cylindrical shape and is largely doubled in a large check patterned (lattice) shaped multi-hole support body (core) and a body circumference of the multi-hole support body 18 integrally formed as a polypropylene resin. It consists of the 1st filter 10a which winds up and it is possible to release | release.

In particular, the first filter 10a is formed by welding and attaching polyester resin felt with an antimicrobial-containing acrylic resin in FIG. 5, and has a close-up body portion 19 on the inner side of the rear end. It has the to-be-adhered surface part 20 which can be attached or detached by hand to the part which meets in a state.

On the other hand, 21 is a second filter thicker than the first filter 10a, and is composed of a continuous bubble body made of polyurethane resin, 22 is a front case accommodating the second filter 21, and the bottom wall thereof. 23 closes the front end opening of the multi-hole support 18, and the passage hole 24 around the bottom wall 23 has an outer cylinder 11a of the first filter 10a and the central cylindrical portion 11. The gap between the gaps is open.

Further, the axial length of the first filter 10a is set slightly larger than the dimension (for example, 80 mm) between the rear wall 25 and the bottom wall 23 (e.g., 82 mm), and both walls 23 ( 25 and the first filter 10a are brought into close contact with each other so that no water is leaked without passing through the first filter 10a due to a gap.

Next, the inlet member 12 inserts the annular weight 26 made of zinc so as to submerge the entire suction structure 3 in the water, and has an inlet having a third filter 27 made of a metal net. The hose 4 is connected to the radially compressed portion (hose connecting portion) 12a.

28 is a vinyl resin tube, 29 is a vinyl chloride resin coil fused around the tube 28, and gives flexibility to the hose 4.

Next, the operation of the suction structure 3 having the above configuration will be described.

First, the suction structure 3 is immersed in the bath water (used) W of the bathtub as a fluid.

Then, when the self-contained pump 2 is operated, the bath water W is discharged from the intake structure 3 by the self-contained pump 2 if a certain amount of the pick-up is in the self-contained pump (usually supplied at the time of supply of tap water). 4) through the washing machine (5) can be supplied into.

At this time, the water sucked in the through hole 17 of the suction terminal 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 circumferential surface of the filter through the first filter 10a.

Here, the passage hole 17 is formed large because the flow rate of water is large in the vicinity of the passage hole 24.

The removal of the dirt by this first filter 10a is performed at a large surface area as three-dimensional filtration, so it is minimal.

As such, the water from which dirt is removed through the first filter 10a is led to the hose 4 through the third filter 27 from the rear end opening 25a of the rear wall 25 through the multi-hole support 18. .

In this case, the third filter 27 is configured to have substantially the same mesh size as the second filter 21, so that the first filter 10a or the first filter 10a and the second filter 21 may be omitted. Even if it does not pass through the filter at all, the contaminated water does not act as a safety filter to be supplied to the washing machine (5).

In order to remove the dirt of the first filter 10a and the second filter 21, first, the suction terminal member 13 is removed from the suction structure 3, and the second filter 21 in the front case 22 is removed. Remove the front case 22 and the multi-hole support 18 from the suction structure 3, and close the first filter 10a wound around the multi-hole support 18 with the body surface 19 by The adhesion state of the surface 20 to be contacted is released and pulled out to remove dirt.

In addition, when the suction structure 3 is not used, the hook member 14 is hooked to the hole 16 of the side wall 15 of the washing machine 5 as described above. Since the bottom is upside down, there is no fear that the water in the suction structure 3 will fall, and the weight 26 is located below the suction structure 3 so that the outlet member having the weight 26 embedded therein ( As the 12 is in close contact with the side wall 15, the generation of vibration (resonance) is prevented even when the washing machine 5 is operated.

Unlike the above embodiment, the weight may be formed in the suction terminal member 13 to immerse the entire suction structure in water.

6 shows another embodiment and corresponds to FIG. 3.

In FIG. 6, 30 is a weight and is inserted into the suction terminal member 13, not into the outlet member 12 of the suction structure 3.

Next, the parcel of the self-contained pump will be described.

FIG. 7 is a block circuit diagram mainly comprising a self-contained pump and a water supply valve directly connected to the water supply, and FIG. 8 is a timing diagram showing the drive timing of the self-contained pump and the water supply valve.

First, in FIG. 7, the control unit 32 is a microcomputer that is in charge of controlling the washing machine 5, and washes and dehydrates according to the key input signal of the key input unit 33 and the detection result by the water level sensor 34. It controls the drive of the drive motor 35 which drives a cylinder and a rotary blade (not shown), the water supply valve 36 directly connected to the water supply, the self-sufficiency pump 2, and the electromagnetic drain valve 37.

In FIG. 8, when the first washing is performed, it is regarded that little of the water is supplied to the self-contained pump 2, so that the water supply valve 36 directly connected to the water is turned on for about 15 seconds, and the tap water is introduced into the water to be fed to the self-contained pump. Turn on (2) to supply the bath water, which is laundry.

During the next step of rinsing (reservoir rinsing, water rinsing, dehydration rinsing), the water in the self-contained pump 2 is usually left with the water remaining at the time of washing. Tap water is turned on only for a second to inject tap water as replenishment powder, and then the self-contained pump 2 is turned on to supply bath water as a rinse water to the washing container.

As described above, the controller 32 changes the supply time of the pick-up water at the time of the first ON of the self-contained pump and at the time of the subsequent ON (for example, by reducing it by about 1/3 as described above), thereby saving tap water and rinsing. The time can be shortened.

According to the present invention, a second cylindrical filter member and another cylindrical filter member are assembled to an intake structure having a disc shaped filter member, and the fluid passes through the disk filter member, and then another cylindrical filter member. The three-dimensional configuration allows the fluid to pass from the outer circumference of the body to secure a large filtration area, and can also remove small dirts and dirt, and at the same time monitor the contamination of the filter and facilitate maintenance work such as cleaning. You can.
