Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a washing machine for general household use, which is provided with a circulating water flow discharge portion projecting inside a washing tub.

Conventional Structure and Problems Conventionally, in this type of washing machine, as shown in Fig. 1, the power of the motor 1 is transferred to
The water in the washing tub 5 is rotated through the pulsator 4,
As the laundry 6 is rotated, the water in the laundry 4!5 passes through a circulation channel 7 by the pumping action of the pulsator 4, and a filter 9 with a bag-like net 8 is removably attached to the washing tub 5. The water is discharged from the circulating water flow discharge part 10 that protrudes inward. A plurality of baffle plates 11 are provided around the inner bottom peripheral wall of the washing tub 5. When the water in the washing tub 6 and the laundry 6 rotate, the water flow is forcibly changed by the baffle plate 11 so that the laundry 6 is turned upside down, and as the laundry 6 rotates horizontally, the Reduces uneven washing. Further, the movement of water in the washing tub 5 is fastest near the inner peripheral wall 12, and the direction of the water flow changes at the corner portion 13, causing water to splash. The baffle plate 11 is connected to this inner peripheral wall 12
The flow in the vicinity is diverted to the inside of the washing tub 5 and decelerated to prevent water from splashing. However, when the amount of laundry 6 is small compared to the amount of water in the washing tub 5 and hot water rinsing is performed, in addition to the high water level at the time of overflow rinsing, the amount of laundry in the washing tub 6 is low. The flow becomes faster;
Due to the centrifugal force, the water level near the inner circumferential wall 12 becomes high, reaching the vicinity of the circulating water flow discharge section 1o, where the water flow collides with the filter 9 and the discharge section side wall section 14, resulting in severe water splashing.

At this time, since the amount of laundry e was small, the flow of water was too strong, and the baffle plate 11 could not prevent the water from scattering. In addition, water splashes also occur at other corner parts 13', but even if water splashes occur at the corner part 13' adjacent to the dehydration tank 15, water will drip onto the dehydration lid 16 etc. and will not be splashed onto the floor surface. However, as shown in the figure, at the corner portion 13 opposite to the dehydration tank 16, there was a problem in that the water splashed as described above drips outside the machine and wets the floor surface.

Purpose of the Invention The present invention solves these conventional problems, and prevents water from splattering (9.
There are many ways to provide a washing machine with reduced

Structure of the Invention The washing machine according to Mei Honjo has a circulating discharge part protruding from a corner of the inner circumferential wall of the washing tub on the side that is not adjacent to the dehydration tank, and the washing machine is further provided above the circulating water flow discharge part from the circulating water flow discharge part. It has a cover that protrudes into the tank, and a lip that connects the lower surface of the cover and the inner circumferential wall near the top of the discharge part, and is arranged vertically.The structure of this cover and the vertical rib prevents washing when rinsing overflows, etc. A watchtower that reduces the force of the water flow with an IJ bulb on the water level in the tank≠
4. The cover prevents water from splashing outside the machine.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. Note that the same reference numerals as in FIG. 1 indicate members having the same functions. As shown in the figure, there is a cover part 17 that projects into the washing tub 5 as a filter above the circulating water flow discharge part 10 that projects from the corner part 13 of the washing tub 6 that is not adjacent to the dehydration tub 16; Several lips 18 are provided vertically to connect to the lower surface and the inner circumferential wall 12 in the vicinity of 1° above the circulating water flow discharge part. With this configuration, when the amount of laundry 6 is small compared to the amount of water in the washing tub 6 and overflow rinsing is performed, the flow of water in the washing tub 6 becomes faster, and centrifugal force causes the water near the inner peripheral wall 12 to flow faster. When the water level becomes high and reaches the vicinity of the circulating water flow discharge part 1o, and the water flow collides with the filter 9 and the discharge part side wall part 14 or exceeds the discharge part side wall part 14, the water flow collides with the lip 18. The force of the water flow near the discharge part side wall part 14 is relaxed by the reflected flow, and the cover part 17 serves as a wall against water splashing that occurs when the water flow collides with the discharge part side wall part 14 or lip 18. This prevents water from splashing out of the machine and making the floor wet.

In addition, by bringing the side edges of the cover part 17 into close contact with the panel 19 and the inner circumferential wall 12 of the washing tub 5, the role of the wall against water splashing is improved, and the action of the lip 18 increases the strength of the cover part. For example, by providing a concave portion or the like on the upper surface of the cover portion 17, the cover portion 17 can be used as a simple storage stand for small articles for washing. Also, reply 18
By providing this, the amount of foaming caused by residual detergent components during overflow rinsing is reduced, without preventing the original movement of the laundry 6, and the time required for rinsing can be shortened.

Effects of the Invention As described above, according to the present invention, when the amount of laundry in the washing tub is small compared to the amount of water and when rinsing with overflowing water is performed, water splashing can be suppressed. By providing a lip connected to the cover nearby, it suppresses the force of the water flow near the water surface near the inner peripheral wall of the washing tub, suppressing foaming during rinsing, and together with the cover, effectively prevents water from splashing.
