Abstract

An automatic washing machine having an improved structure. The sprinkling member for repeatedly sprinkling the washing water into the dehydrating tub comprises a removable washing tub lid, an adapter for permitting the washing water to be fed therethrough and a guide member forming, in cooperation with the washing tub lid, a sprinkling nozzle through which the washing water is sprinkled into the dehydrating tub. The lint filter filters off lints generated in the washing cycle and permits the filtered lints to be automatically removed therefrom so as to be drained off the washing machine along with the drained water. The circulation pump circulates the washing water and is connected to the washing tub and the sprinkling member in such a manner that it permits the washing water in the washing cycle to be drawn up to the sprinkling member through the lint filter and also permits the used washing water in the draining cycle to downwardly pass through the filter so as to be drained off the washing machine. This washing machine thus causes the detergent particles to be finely ground by the rotation of the pump impeller so as to be completely dissolved in the washing water and permits the lints generated in the washing to be filtered off and in turn automatically discharged therefrom.

Claims

1. A washing machine comprising a housing having a control panel at its upper part, a power transmission being connected to a reversible drive motor by means of a drive belt and a driven pulley, a washing tub, an agitator vane wheel being rotatably mounted on an upper part of said power transmission, a dehydrating tub which has a plurality of through holes at its side wall and is disposed in said washing tub for rotation inside the washing tub and a water feed control valve being disposed on an upper part of the washing tub and being adapted to control the water feeding, the improvement comprising:

sprinkling means for repeatedly sprinkling washing water into said dehydrating tub, said sprinkling means including a removable washing tub lid forming an upper part of said means and having a sprinkling guide surface, an adapter being provided at a side of said washing tub lid and permitting the washing water to be fed to said means therethrough and a guide member forming, in cooperation with the washing tub lid, a sprinkling nozzle through which the washing water is sprinkled into the dehydrating tub;

lint filtering means for filtering off lints generated in the washing and permitting the filtered lints to be automatically removed therefrom so as to be then drained off the washing machine, said lint filtering means communicating with the washing tub and said adapter of the sprinkling means; and

circulation pump means for circulating the washing water, said circulation pump means being connected to the washing tub and the sprinkling means in such a manner that it permits the washing water in washing cycle to be drawn up to the adapter of the sprinkling means through the lint filtering means and permits the used washing water in draining cycle to downwardly pass through the filtering means so as to be drained off the washing machine, thereby causing the lints in the washing water to be filtered off by the lint filtering means during the washing cycle and to be automatically removed from the lint filtering means during the draining cycle.

2. A washing machine according to claim 1, wherein said guide member of the sprinkling means is provided with an outer discharge slit for permitting the washing water to be introduced to a space between said washing tub and said dehydrating tub and the washing water sprinkled from said sprinkling nozzle is guided by said sprinkling guide surface of the washing tub lid.

3. A washing machine according to claim 1, wherein said lint filtering means is provided therein with a filtering net.

4. A washing machine according to claim 1, wherein said lint filtering means is provided at its upper and lower parts with a check valve, respectively.

5. A washing machine according to claim 1, wherein said lint filtering means is connected at its lower end to a drain valve.
