Description

Structure of guide filter for washing machine

The present invention relates to a structure of a guide filter for a washing machine, and more particularly, to a structure of a guide filter for a washing machine to allow washing water to overflow, regardless of the water level, so that foreign substances contained in the washing water are filtered out to the filtering network.

Generally, washing machines are classified into vortex type, drum type, and stirring type according to the washing method, and among the washing machines, vortex type washing machines are most widely used. Such vortex type washing machines have a washing stroke in one tank (washing tank), The rinsing stroke and the dehydration stroke are performed in a batch.

1A and 1B, there is shown a conventional washing machine. In the washing machine, a cylindrical water tank 11 containing laundry water is suspended by hook rods inside a box 10. A plurality of water holes are formed in the water storage tank 11, and a washing tank 12, which is a cylindrical body in which laundry and washing water is accommodated, is installed in a concentric circle, and a pulsator for generating water flow in the lower portion of the washing tank 12. (13) was installed. The pulsator 13 and the washing tank 12 have dual drive shafts and are axially coupled to the reduction gear assembly 15 mounted on the bottom surface of the water storage tank 11 so that the pulsator during the washing and rinsing process is performed. Only 13) is reversed and reversed, and during the dehydration stroke, the pulsator 13 and the washing tub 12 are integrally rotated in one direction, and the reduction gear assembly 15 has a driving motor (one side). 14) and the V-belt is linked.

The upper plate 20 of the outer box 10 is provided with a control unit, an electric cabinet 19 and a top plate 20 provided with a door, a balance 16 is installed on the upper end of the washing tank 12, The shower ring 17 is installed at the upper end of the reservoir (11).

And one side wall of the washing tank 12 is provided with a guide 21 is coupled to the filter net holder 22, the filter net holder 22 is coupled to the filter net 23 is coupled through the guide 21 The filter net 23 was to filter out the foreign matter contained in the wash water.

By the way, the filter net 23 as described above is generally located at the upper end of the washing tank 12, there is a problem that becomes obsolete when the amount of washing water contained in the storage tank 11 or the washing tank 12 is small.

In more detail, the guide 21 in which the filtering net 23 is installed is installed with the bottom portion located close to the pulsator 13, and the upper end portion located near the balance 16 of the washing tank 12. In addition, since the filter net holder 22 is installed at the upper end to hold the filter net 23, washing water must be accommodated in the water storage tank 11 higher than the height of the washing tank 12, but the guide 21 and the filtering net 23 are Through the back flow into the washing tank 12, during the washing and rinsing at low water level through the guide 21 and the filter network 23 to prevent the washing water backflow to filter out foreign substances contained in the washing water There was a problem that the filter net 23 can not perform its function.

Reference numeral 18 designates a water supply valve, and 21 designates a connecting tube for fluidly connecting the water supply valve 18 and the shower ring 17.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a structure of a guide filter for a washing machine, which causes the washing water to overflow regardless of the water level so that foreign matters contained in the washing water are filtered out to the filtering network. will be.

The present invention is a washing machine equipped with a filtering network for filtering out the foreign substances contained in the washing water flowing back into the washing tank to achieve the above object, the first to third so that the filtering network is installed with different heights on the front surface of the guide The opening part is formed, the first to third openings are formed separately from the first to third passages, the washing machine in which the first to third valve plate is installed in a horizontal state at the bottom inlet of the first to third passages To provide a guide filter structure for.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

2 and 3 illustrate a structure of a guide filter for a washing machine according to the present invention. The structure of the guide filter for a washing machine includes first and third openings 211, 212, and 213 having different heights, and the first filter. It is composed of a guide 210 having a respective passage in the third to third openings 211, 212, 213.

The guide 210 is a vertical plate body, the first opening portion 211, the second opening portion 212, the third opening portion 213 is formed side by side at equal intervals by varying the height on the front surface, the second A first guide cylinder 215 and a second guide cylinder 216 are formed on the rear surface of the guide 210 having the opening 212 and the third opening 213. The first to third openings 211, 212, and 213 are each provided with a filtering network 214, and different passages are provided. The first opening 211 is formed with a first passage 217 which is integral with the side wall of the washing tank 12, the second opening 212 is formed by the first guide cylinder 215 The third opening 213 is formed by the second guide cylinder 216.

In addition, second and third valve plates 310 and 311 are horizontally installed at the bottoms of the first and second guide cylinders 215 and 216, and a first sidewall of the washing tank 12 is provided in the first passage 217. The valve plate 300 is installed horizontally, and the first to third valve plates 300, 310, and 311 are horizontally formed, respectively, and one end of the valve plate 300 is fitted to the binding pin 312 formed to protrude vertically again. Thus, one end of the first to third valve plates 300, 310 and 311 is restrained by the binding pin 312 so that the other end is lifted upward or restored to the original horizontal direction.

When the amount of the washing water contained in the washing tank 12 or the water storage tank does not reach the second valve plate 310, the present invention configured as described above may pressurize the third valve plate 311 of the third passage 219. At the same time as the opening to the inside of the washing tank 12 through the third opening (213).

When the water level does not reach the first valve plate 300, the second valve plate 310 and the third valve plate 311 of the second passage 218 and the third passage 219 are hydraulically opened. Simultaneously with this, the second opening 212 and the third opening 213 are circulated into the washing tub 12. Finally, in the case of the high water level, the first to third passages 217, 218, 219 are circulated to the inside of the washing tank 12.

So, regardless of the small, medium, and high water level, the washing water is recirculated into the washing tank 12 through the filtering network 214 of the guides 210, thereby smoothly filtering out foreign substances contained in the washing water.

In the accompanying drawings, reference numeral 13 denotes a pulsator, and 16 denotes a balance.

As described above, according to the present invention, by forming three openings having different heights in the guide and by forming a separate passage in the opening, the washing water is recirculated into the washing tank through the filter net regardless of the water level. It will be effective to filter out foreign matter contained in the water more smoothly.
