Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine, and particularly to a single-tub fully automatic washing machine.

Conventionally, in fully automatic washing machines, when adding detergent during washing, the detergent was poured into the washing tub in powder form after the clothes were loaded and the water was supplied, so it took a long time for the detergent to dissolve in the water. Especially in the case of powdered soap, it is difficult to dissolve in cold water, so
It takes double effort to dissolve it in a container and then put it into the washing tub.
The image of the machine as a fully automatic washing machine was diminished. In addition, in conventional fully automatic washing machines, when adding detergent to wash clothes, the detergent was added appropriately depending on the amount of laundry and the amount of water, depending on the feel of the water in which the clothes were washed. There was a drawback that washing could not be carried out using the optimum amount of detergent for washing. Furthermore, in conventional fully automatic washing machines, as a method of removing cloth waste floating in the washing water during washing, cloth waste was removed by fixing a collection net to the top of the inner tank side wall. However, this method has the disadvantage that it can only work under certain conditions, and no great effects could be expected. As described above, conventional fully automatic washing machines have many drawbacks and cannot perform laundry in the most efficient manner as a fully automatic washing machine.

A first object of the present invention is to provide an efficient method for adding detergent and a washing machine equipped with the device, in order to eliminate the drawbacks of the above-mentioned prior art and enable efficient laundry work. . Another object of the present invention is to provide a washing machine having a function of effectively removing cloth waste floating in washing water during washing. In order to achieve the above-mentioned first object, the present invention provides an inner cover detachably or integrally with the top cover at the clothes inlet of the top cover provided at the upper part of the outer frame of the washing machine, and the inner cover has a detergent receptacle. By installing a box and putting detergent into this detergent receiving box and supplying water to this detergent receiving box, the water flowing out from the water inlet passes through the detergent receiving box provided on the inner lid and enters the inner tank.
The structure is such that water is supplied into the inner tank while dissolving the detergent. In addition, in order to achieve the second objective, the washing machine is equipped with a forced circulation pump, and a detergent receiving box having the above-mentioned configuration and a filter function is installed, and the washing water in the inner tub is transferred to this detergent receiving box. By forcibly circulating the washing water through the washing machine, it collects the cloth waste floating in the washing water in the inner tank, and at the same time dissolves the detergent and soap in the detergent receiving box well before putting it into the inner tank. be.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, a top cover 2 is provided on the upper part of an outer frame 1, a panel 4 is provided on the top cover 2, a timer dial 5 is provided on the panel 4, and a lid 3 that opens and closes when putting in and taking out clothes is provided. It is provided. FIG. 2 is a diagram showing the external appearance of the washing machine shown in FIG. 1 when the lid 3 is opened. Clothes are thrown into the inner tub of the washing machine through the clothes slot 6 provided on the top cover 2. 3 and 4 are partial external views of a single-tank fully automatic washing machine in which the present invention is implemented. A state in which the lid 7 is opened is shown. A detergent receiving box 8 is provided in the center of the inner lid 7, and detergent and soap are put into the detergent receiving box 8 in the state shown in FIG. FIG. 5 shows a state in which the inner lid 7 is removably attached to the clothes slot 6 of the top cover 2, and the inner lid frame 9 of the inner lid 7 is attached to the clothes slot 6 by the lid frame claws 10. In this way, by making the inner cover 7, which is a separate member, removably attached, it is not necessary to modify the top cover type, and it is possible to provide commonality to various types of washing machines, resulting in an inexpensive product. Furthermore, when the inner cover 7 is not needed, it can be easily removed and used as a conventional fully automatic washing machine.

FIG. 6 is a sectional view of the embodiment of the one-tub fully automatic washing machine according to the present invention. In the figure, inside the outer frame 1, an outer tank 12 is suspended from an upper corner portion of the outer frame 1 by four hanging rods 11. A motor 16, a clutch case 21, a drain valve 22, etc. are provided at the bottom of the outer tank 12. When driving the pulsator 14 that moves the clothes at the center bottom of the inner tub 13 during washing, the motor 16
The rotation of
4 rotates. During dehydration, the inner tub 13 is rotated by the action of the clutch in the clutch case 21, and the water contained in the clothes is dehydrated by centrifugal force into the outer tub 12 through the dehydration hole 15 provided on the side wall of the inner tub 13. do. When draining water, the water is drained out of the washing machine through the drain hose 20 by operating the drain valve 22. At the start of washing, when clothes (not shown) are put into the inner tub 13 and water is supplied, the washing water 25 discharged from the water inlet 24 by the operation of the water supply valve 30 is poured into the detergent receiving box 8 of the inner lid 7. Water is supplied into the inner tank 13 while dissolving the detergent 26 contained therein. In this way, by injecting water into the inner tank 13 while dissolving the detergent/soap in water, the cleaning effect can be improved, and this is particularly effective for detergents and soaps that are difficult to dissolve. I can do it.

FIG. 7 is an enlarged view of the inner lid 7 of the washing machine, in which a detergent receiving box 8 is located in the center of the inner lid 7. On the side wall of the detergent receiving box 8, measuring lines are printed as low, medium, and high so that the amount of detergent can be accurately measured according to the amount of water supplied into the inner tank 13. In addition, a filter 28 having a mesh that does not allow detergent/soap particles to pass through is provided at the bottom and side walls of the detergent receiving box 8.The filter 28 has a mesh that does not allow detergent/soap particles to pass through.
A detergent solution is introduced into the inner tank 13 from the filter 28 section.

FIG. 8 is a cross-sectional view of a fully automatic washing machine with a forced circulation pump, which is another embodiment of the present invention.
The same reference numerals as in the figure indicate the same parts. This is done by attaching a forced circulation pump 31 to the bottom of the outer frame 1 of a fully automatic washing machine, connecting a circulation pipe 32a to the bottom of the outer tank 12, and connecting the forced circulation pump 31 to the inlet 24 through the circulation pipe 32. By circulating the washing water, the detergent 26 placed in the detergent receiving box 8 provided in the inner lid 7 is dissolved and thrown into the inner tank 13.
Such water circulation is always performed during washing and rinsing, and after dissolving the detergent as described above, the detergent receiving box 8, which also serves as a filter,
Remove fabric debris floating in the washing water.

Finally, another function of the inner lid used in the present invention will be described. In conventional fully automatic washing machines, when the lid was opened to load clothes, a washing and dehydrating tub was revealed, and clothes were loaded through the clothes slot in the top cover and washed. Therefore, if the lid is opened during washing or dehydration, there is a risk that the rotating object may be easily touched. When the lid is opened during dehydration, the power is automatically turned off and the brake is applied, but it takes about 10 seconds for the dehydration tank to stop once the brake is applied, and the switch does not work unless the lid is opened a certain distance. Because of their structure, conventional washing machines were dangerous. In contrast, in the present invention, an inner cover is provided at the clothes slot of the top cover, and this inner cover is provided with many functional parts necessary for washing, so that the rotating objects are not touched by hands during spin-drying, making it safe. performance is significantly improved.

As described above, the present invention provides a top cover 2
The inner lid frame 9 is provided with an inner lid 7 that can be freely opened and closed, and the lower part of the inner lid frame 9 has an inner lid frame 9 attached to the inner edge of the clothing slot 6. A plurality of lid frame claws 10 that can be freely engaged and detached are provided, and the inner lid 8
A detergent receiving box 8 having a filter 28 is located in the center of the box.
This is characterized in that a water passage 27 is formed in the inner lid 8 for guiding the water supply from the water inlet 24 to the detergent receiving box 8.

According to this configuration, the following actions and effects can be expected.

(1) Since the detergent is dissolved by pouring water and the washing liquid is applied to the laundry, the detergent can be evenly absorbed into the laundry.

(2) When it is better not to have the inner lid frame 9 when putting in or taking out a large piece of laundry, the inner lid frame 9 can be easily removed from the clothes slot 6 of the top cover 2.

(3) The inner lid frame 9 is connected to the clothes slot 6 of the top cover 2.
Since it is securely attached to the top cover 2 with the lid frame claw 10 that engages with the inner edge of the inner lid frame 9, there is no fear that the inner lid frame 9 will come off due to vibrations during dewatering.

(4) It is safe because the inner lid 8 and the lid 3 form a double lid.

That is, when the lid 3 is opened during dewatering, a brake is applied and the rotation of the inner lid 13 is suddenly stopped. After applying the brakes, it takes about 10 seconds to stop. During this time, the rotating inner tank 13
It is dangerous if you put your hand inside. However, since there is an inner lid 8, it is impossible to put your hands into it. It takes some time to finish opening the inner lid 8. During this time, the rotation of the inner tank 13 almost stops, so there is no danger and it is safe.
