Description

[Detailed Description of the Invention] This invention relates to a washing machine that forcibly circulates washing water through a side channel using the back blade of a pulsator and removes lint by installing a filter in the middle of the side channel.

Normally, the pulsator of a washing machine has different motor rotation speeds in 50Hz and 60Hz areas, resulting in a difference in cleaning rate, or because the increased rotation speed can damage the fabric, so depending on the area, you may need to change to a special pulsator. The problem was solved by changing the pulley that was directly connected to the pulsator.

For this reason, for example, the inclination angle of the pulsator mountain is made different on the left and right sides, and the reversal time of the motor is set to vary depending on the area (Utility Model No. 55-1).
30681) has also been proposed, but this requires wiring switching, and the switching work is complicated, making it difficult for users to do it themselves.

Therefore, the present invention has been devised in view of the above points, and it is an object of the present invention to provide a washing machine with a convenient structure that uses one type of pulsator and can be switched with a simple operation.

Therefore, in this invention, the front and back blades of the pulsator are
It is formed by twisting blades for 0 Hz and 60 Hz, and switching can be performed by simply installing the pulsator in reverse. Furthermore, since there is only one type of pulsator, manufacturing is simplified and inventory management is streamlined. Excellent effects can be obtained.

An embodiment of the present invention will be described according to the drawings.

FIG. 1 shows a perspective view of the washing machine of the present invention. 1 is a housing made of steel plate or synthetic resin.

2 is a washing tub, 3 is an overflow port, and 4 is a lint filter.

Reference numeral 14 denotes an operation panel on which a washing/rinsing switching lever 11, a washing timer 12, a dehydration timer 13, etc. are lined up.

17 indicates a dehydration tank. 9 indicates a hose for overflowing water during rinsing and for draining water after washing is completed.

FIG. 2 is a sectional view taken along line A-A' in FIG.

5 is a pipe for overflowing water, 6 is a side path for circulating washing water for removing lint, and a filter 4 is provided at the water inlet to the washing tub 2.

7 is a pulsator with blades having twists on both sides for 50Hz and 60Hz, and the twists for 50Hz are deeper than those for 60Hz, so that there is no difference in washing power in each area.

Reference numeral 16 indicates a rotating shaft directly connected to the pulsator, and 15 indicates a pulley coupled to the rotating shaft 16.

8 is a valve body that opens and closes in conjunction with a switching lever on the operation panel.

That is, it is closed during washing and rinsing, and opened when draining water.

In this configuration, the pulsator 7 is installed with the blade surface for 50H2, which has a deep twist, facing upward in the 50Hz area, and vice versa.
In the Hz area, use a shallow-twisted 60Hz blade with the blade side facing up.

At this time, the water flow to remove thread waste is 60H in a 50Hz area.
Since it is weaker than in the z area, the design should be such that sufficient water flow can be obtained in the 50 Hz area.

Moving from a 50Hz area to a 60Hz area or vice versa
When moving to a 50Hz area, you can simply turn the pulsator over using a screwdriver or a coin and reinstall it.

In the above-described washing machine that uses the back blade of the pulsator to forcibly circulate washing water through the side channel and removes lint by installing a filter in the middle of the side channel, there are 50Hz and 60Hz waves on both sides of the pulsator, respectively. Since the twist of the blades can be selected depending on the area, it is possible to easily replace the pulsator or the pulley, which previously required replacing the pulsator and the pulley.
There is no need to stock 0Hz pulsators or pulleys, and one type of pulsator is sufficient, which improves parts inventory management and serviceability.
