Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a washing machine in which water in a water tank is discharged from a drain port at the bottom of the water tank through a filter member that has a plurality of water passage holes.・Regarding this.

[Technical front of the invention and its issues] Conventionally, for example, a rotating tank was installed in a water receiving tank. In the tiered dewatering/washing machine, a pine bar,
A filter member for capturing foreign objects such as hairpins and buttons was not provided. As a result, these foreign objects flowed from the IJ1 water outlet into the 1) water pipe connected to this and got caught in the 171 water valve installed in the middle of the R1 drain pipe, causing the drain valve to completely close. There was a problem that it could not be closed and water leaked.

In order to solve this problem, a configuration in which a filter member having a large number of water passage holes is provided at the IJF water inlet can be considered. In this case, if the opening diameter of the water passage hole is set small, the ability to capture foreign matter will be affected by itself, and the water passage hole will be easily clogged with lint being drained, and the water passage performance of the filter member will be affected by the water drainage. The disadvantage is that performance is reduced.

On the other hand, if the opening diameter of the water hole is set large, tributes such as pine sticks and hairpins whose cross section is smaller than the size of the water hole J: will take advantage of the water flow and pass through the water hole and be drained. It tends to flow out to the mouth side, making it difficult to capture foreign substances.

[Objective of the Invention 1] The present invention was developed in consideration of the above circumstances, and its object is to prevent foreign objects such as matchsticks, hairpins, buttons, etc. from being flushed out of the drain; I
An object of the present invention is to provide a washing machine that can maintain J+ water quality well.

[I of invention! Summary J The present invention allows water in a water tank to flow out from a drain port at the bottom of the water tank through a filter member having a plurality of water holes, the filter member being connected to the water tank. It is characterized in that it is arranged so as to form a gap of a predetermined height that connects to the drain port between the bottom part and the bottom part, so that one end of foreign objects with a small cross-sectional shape such as a matchstick or hairpin can be prevented from flowing into the water flow. Even if the foreign matter falls into the insertion hole, one end of the foreign matter hits the bottom of the water tank, thereby preventing the foreign matter from flowing out.

[Embodiment of the Invention] Hereinafter, an embodiment in which the present invention is applied to a dehydrating and washing machine will be described with reference to FIGS. 1 to 3. 1 is the outer box of the washing machine,
2 is a water tank installed in the outer box 1 via a spring-loaded hoist 3; 4 is a rotary tank installed in the water tank 2 via a dewatering shaft 5; the peripheral wall thereof has a large number of dewatering holes; (not shown). Reference numeral 6 denotes a container-shaped stirring body disposed within the rotating tank 4, 7 a motor disposed below the water receiving tank 2, 8 selectively transmitting the power of the motor 7 to the rotating tank 4. It is a power transmission mechanism. On the other hand, 9 is a drain port formed at the bottom of the water receiving tank 2;
0 is the vF* pipe connected to u1 water eye 9, 11 is the drain pipe 10
1 water valve installed at the inlet, 12 is tJl water pipe 10
This is a drainage pump installed in the middle of the drain.

Now, 13 is a filter member, which has an annular shape with the same size as the bottom of the sea urchin water receiver W42 shown in FIG. 1
71. The filter member 13 is fitted into the dewatering shaft 5 and placed in the water receiving tank 2 by placing it on the upper end of a plurality of protrusions 15 of a predetermined height, e.g. As a result, a gap 16 (see FIG. 1) of a predetermined height (for example, 51i+) connected to the drain port 9 is formed between the filter member 13 and the bottom of the water receiving tank 2. In this case, the water passage hole 14 is not located directly above the drain port 9.
First, the operation of the above configuration will be explained. After the washing operation ends L7, when the drain valve 11 is opened and the drain pump 12 is started, the water in the water receiving tank 2 flows into the filter member 1.
Water flows into the gap 16 through the water hole 14 of No. 3, and drains into the drain port 9.
The water is discharged from the machine through a drain pipe 10 and a drain pump 12. At this time, it goes without saying that among the foreign objects contained in the waste water, foreign objects such as buttons, which are larger than the opening diameter of the water passage hole 14, are captured by the filter member 13.
A foreign object a (see FIG. 3), such as a matchstick or hairpin whose cross-sectional shape is smaller than that of the water passage hole 14, may fall into the water passage hole 14 with one end thereof riding on the water flow.

However, in this embodiment, since the filter member 13 is arranged so as to form a gap 16 of a predetermined height between the filter member 13 and the bottom of the water receiving tank 2, one end of the foreign material a can pass through as shown in FIG. Even if the foreign matter a falls into the water hole 14, the lower end of the foreign matter a immediately hits the bottom of the water receiving tank 2, and in this state, the foreign matter a is prevented from flowing out any further.

In this way, in this embodiment, not only can foreign objects such as buttons larger than the water passage hole 14 be captured, but also elongated foreign objects such as matchsticks and hairpins can be captured by the cooperative action of the filter member 13 and the bottom of the water receiving tank 2. This can prevent these foreign substances from being flushed out from the drain port 9 to the drain valve 11 side, thereby preventing the drain valve 11 from being flushed out from the drain port 9.
Malfunctions of the drain pump 12 and foreign matter suction accidents of the drain pump 12 can be prevented. Moreover, as described above, the tribute can be captured by the cooperative action of the filter member 13 and the bottom of the water receptacle 112, which is different from the conventional method. There is no need to set the water hole 14 to a small value, and therefore, the opening diameter of the water hole 14 can be increased to a certain extent while ensuring the capture performance, and it is possible to prevent the water hole 14 from clogging due to thread waste during drainage, thereby reducing drainage. can maintain good health.

In the above embodiment, the filter member 13 is disposed so as to form a gap fl116 between the filter member 13 and the entire bottom surface of the water receiving tank 2. However, the present invention is not limited to this. A portion of the bottom of the receiving tank 2 that is connected to the drain port 9 is partially recessed to form a concave portion 17, and a filter member 19 is arranged so as to form a gap 18 that is continuous to the drain port 9 between the bottom portion of the receiving tank 2 and the concave portion 17. It is also possible to have a configuration in which it is set. In addition, the present invention can be modified in various ways without departing from the gist, such as being applicable not only to dehydrating/washing machines but also to dual-tub washing machines.

[Effects of the Invention] As is clear from the explanation below-1-, the present invention provides a method in which a filter member having a water passage hole is connected to a drain port between the bottom of the water receiving tank and the bottom of the water receiving tank.
Since the arrangement is such that a gap of a predetermined height is formed between the filter member and the bottom of the water tank, it is possible to not only capture large foreign objects such as buttons, but also elongated foreign objects such as matchsticks and hairpins between the filter member and the bottom of the water tank. can be captured by cooperative action,
We have created a washing machine that has the excellent effect of preventing these foreign substances from being flushed out of the drain, and also preventing clogging of the water passage hole due to lint in the drain, and maintaining good drainage. I can help.
