Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a washing machine used in general households.

Structure of conventional example and its problems Conventionally, this type of washing machine, as shown in Figs. 1 and 2,
a washing/dehydration tank 2 having a washing wing 1 approximately in the center of the inner bottom;
It consists of a water receiving tank 3 containing this washing and dehydrating tank 2, and an outer box body 4 containing these. Said washing and dehydration tank 2
A mounting plate 5 is provided on the lower end surface of the mounting plate 6, and the mounting plate 6 has an opening 6 through which the water in the tank 2 passes toward the washing blade 1 side.
This opening 6 is provided to be large in order to reduce the resistance to the passage of water in the tank 2.

A pump blade 7 is provided on the back side of the washing blade 1, and the water in the tank 2, which is energized by the pump blade 7, is pumped through a pumping channel 8 arranged on the side wall surface of the washing and dewatering tank 2. The lint in the tank 2 contained in this discharged water is discharged to the filter 9 at the opening at the tip of the pumping channel 8 and flows into the tank 2 again. It is configured to be captured and collected. The water in the tank that has been lifted up by the pump blades 7 of the washing blade 1 is pumped up again through the opening 6 at the bottom of the washing/dehydration tank 2 and is circulated. If you wash the clothes with coins in them, the coins will spill out into the washing/dehydration tank 2 during washing, and the coins will get into the gap S between the washing wing 1 and the washing/dehydration tub 2, causing the washing wing to With one rotation,
The coin that entered falls into the lower part of the washing wing 1, and furthermore,
Water sometimes fell into the water receiving tank 3 from the opening 6 on page 23 of the washing and dehydrating tank. When the washing is finished and the dehydration process begins, the washing and dehydration tank 2
When the coin rotates, a dropped coin may be blown outward by centrifugal force and damage the outer water tank 3, or the coin may become stuck between the washing and dewatering tank 2 and the water tank 3.
When the washing machine was clogged, force was applied and the water receiving tank 3 was damaged, causing the water to leak, causing the inconvenience that it could no longer function as a washing machine.

In addition, in order to prevent the coins from falling, the gap S between the washing blade 1 and the washing/dehydration tank 2 may be made small, but if the washing blade 1 is eccentrically deformed due to variations in molding, etc. The gap S could not be made smaller because it would rub against the dehydration tank 2 and become difficult to rotate.

Purpose of the Invention The present invention is intended to solve the above-mentioned conventional problems, such as when coins or the like accidentally mixed into the tank get caught between the washing and dehydration tank and the water receiving tank during the dehydration operation, or when the centrifugal The purpose of this is to prevent the water tank from being damaged or destroyed by coins thrown out by force, thereby preventing water leakage.

Structure of the Invention In order to achieve the above object, the present invention has an annular rib protruding from the outer periphery of the opening provided at the bottom of the washing tub located at the lower part of the washing wing, and a ring rib provided at the outer periphery of the opening provided on the back surface of the washing wing. By providing an annular lip on the outside and close to the annular lip, and placing a pump blade on the outside of this annular lip, coins, etc. accidentally mixed into the washing tub can be removed from the area around the washing vane. prevents water from entering through the gap and falling to the bottom of the washing wing, and further from falling into the inner bottom of the washing tub from the opening to the water receiving tank side,
It is possible to prevent damage to the water tank due to coins and water leakage due to destruction. This is how it was done.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In this Fig. 3, Fig. 1 and 2 shown in the conventional example are compared.
Parts that are the same as those in the figure are given the same numbers. Five pages of annular ribs 10 are provided on the upper surface of the outer periphery of the opening 6 provided at the inner bottom of the washing/drying tub 2 at the approximate center thereof. On the back side of the washing blade 1 located above the opening 6, an annular lip rm is provided so as to protrude outside and close to the substantially annular rib 10 formed on the upper surface of the outer periphery of the opening 6. There is.

A pump blade 7 is provided outward from an annular lip 1111 provided on the back surface of the washing blade 1 to pump up water in the tank from a pumping channel 8.

Next, the operation of the present invention will be explained.

If a coin or the like accidentally gets mixed in during washing, the coin gets stuck in the gap S between the washing wing 1 and the washing/dehydration tank 2, and falls into the lower part of the washing wing 1 during rotation.

This fallen coin is rotated by the pump blade T or the like, but since there is an annular lip 1o on the upper surface of the outer periphery of the opening 6, the coin does not crawl toward the center. Also, even if the coin moves up and down at the bottom of the washing wing 1, the washing wing 1
Since a similar annular lip 11 is protruded from the back surface of the coin in the vicinity of the annular lip 1o, the coins are prevented from entering further inside, and as a result, the coins are prevented from falling into the water receiving tank 3. There is no such thing.

Page 6 Therefore, a washing/dehydration tank 2 having a washing blade 1 at the approximate center of the inner bottom is installed inside the water receiving tank 3, a pump blade 7 is provided on the back surface of the washing blade 1, and the pump blade 7 is used for urging. The water in the tank is discharged into the tank 2 from the lower opening of the washing and dehydrating tank 2, through the pumping channel 8 provided on the wall of the washing and dehydrating tank 2, and from the filter 9 at the tip opening. An annular lip 1o formed protrudingly on the upper surface of the outer periphery of the opening 6 provided in the center of the tub 2 and an annular lip 11 provided on the back surface of the washing wing 1 outside and close to this rib 10, prevent the inside of the tub 2 from being washed during washing. This means that coins, buttons, etc. dropped into the machine will no longer have any negative effects.

Effects of the Invention As described above, the present invention provides an opening in the center of the inner bottom of a washing tub housed in a water receiving tank, a washing blade is visible in this opening, and the outer edge of the opening is This has a great practical effect in that it prevents the water tank from being damaged by coins, buttons, etc. by erecting ribs in an annular shape.
