Description

[Detailed description of the invention] The present invention relates to a washing machine in which a washing tub is provided with a sink board that protrudes inward.Horizontal ribs are provided on the washing tub's washing tub surface to prevent water from splashing. The purpose is to prevent

In a conventional washing machine, as shown in Figs. 1 and 2, a washing machine board 1 is provided at the rear right corner of the washing tub 2 when viewed from the front, and the function of this washing machine board 1 is to In this case, the laundry 3 is turned upside down and water is prevented from splashing.

Here, the washing machine transmits the power of the motor 4 to the pulsator 7 via the V-belt 5 and the impeller pulley 6, rotates the pulsator 7, and rotates the water in the washing tub 2 and the laundry 3. At this time, if the washing board 1 is not provided, the laundry 3 will only be rotated horizontally, and uneven washing will likely occur. So Jiyama board 1
The flow of water was forcibly changed to cause the laundry 3 to be turned upside down.

Further, the movement of water in the washing tub 2 is fastest near the side wall 8 of the washing tub 2, and water splashes occur at the overflow filter 9 and corners. The wall board 1 diverts the flow near the side wall 8 to the inside of the washing tub 2 and decelerates it to prevent water from splashing. However, when the amount of laundry 3 is small compared to the amount of water in the washing tub 2, the flow near the side wall 8 is too strong and the wall plate 1 cannot prevent water from splashing.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and embodiments thereof will be described below with reference to FIGS. 3 to 6. Note that the same reference numerals as those in FIGS. 1 and 2 indicate members having the same functions, and hence will be explained.
As shown in the figure, a plurality of horizontal ribs 10 are provided on both sides of the board 1 at appropriate intervals in the vertical direction.
11 and 12 are provided.

Here, as mentioned above, the function of the jamming board 1 is to decelerate the flow of water near the side wall 8 caused by the rotation of the pulsator 7 by turning it inward as shown by the arrow a in FIG. One example of this is to prevent water from splashing.

However, compared to the amount of water in the washing tub 2, the laundry 3
When the amount of water is small, the flow is too fast and the second
As shown in the figure, water rides on the wall board 1, causing water to splash 13.

However, as mentioned above, the horizontal ribs 10,1
1 and 12, it is possible to suppress water from running onto the wall board 1, as shown in FIG. 6, and to prevent water from splashing upward.

Conventionally, when the water level is low, as shown in FIG.
According to the embodiment, water may run onto the sloped portion 14 at the bottom of the sloping board 1, thereby weakening the force of water running onto the sloped portion 14 at the bottom of the board 1. , can prevent water from splashing.

In addition, the rectifying action of the horizontal ribs 10, 11, and 12 suppresses ripples on the water surface during washing, and reduces water loss due to overflowing through the overflow filter 9.

Furthermore, by setting the formation positions of the horizontal ribs 10, 11, and 12 to correspond to the overflow position A, high water level B, and low water level C, respectively, as shown in FIG. It becomes easier to adjust the water level at a low level, and by indicating the dependence on overflow, it is possible to call attention not to pour more water than necessary into the washing tub 2.

As described above, according to the present invention, when the amount of laundry is small compared to the amount of water in the washing tub, it is possible to prevent water from scattering before it splashes, and in particular, the rectifying action of the horizontal ribs makes it possible to suppresses the ripples of
Splashing of water can be effectively prevented, and water loss due to overflow from an overflow filter, for example, can be reduced.
