Abstract

PURPOSE:To increase capacity while keeping the main body dimension of an existing fully automatic washing machine without changing the height of a balance ring. CONSTITUTION:A circular rib 18 positioned at an intermediate point between a balance ring inner peripheral face 14a and an inner peripheral face 15a of a cover 15 is provided on the upper surface of a balance ring 14. Thus, washing capacity can be increased by adding the circular rib to the existing balance ring.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a balance ring provided on an upper part of a washing / dehydrating tub of a fully automatic washing machine.

[0002]

2. Description of the Related Art The conventional technology has responded by reviewing the height of the balance ring and the height of the outer frame in order to increase the capacity by making the installation dimensions (width, depth) the same as before. However, the overall height of the washing machine tends to increase.

[0003]

In the above-mentioned prior art, it is possible to wash a large amount of laundry with a compact body size, but since the overall height of the washing machine body is increased, The distance from the laundry inlet to the bottom of the washing / dehydrating tank has become longer. Therefore, there is a problem that it is difficult to remove the laundry from the washing / dehydrating tub.

One of the factors that increase the overall height of the washing machine main body is that the height of the above-mentioned balance ring is high. The reason for this is explained. If you try to make it easier, the laundry will pop out. There were some items of concern such as water splashing due to the water flow. Therefore, the height of the balance ring was increased to clear the above concerns.

The present invention solves the above-mentioned popping-out and splashing of laundry, and enables a large capacity while keeping the height of the balance ring the same as it is.

[0006]

In order to achieve the above object, an annular rib is provided on the upper surface of the balance ring. The circular ring rib was provided at an intermediate point between the inner peripheral surface of the cover and the inner peripheral surface of the balance ring attached to the upper part of the outer tank enclosing the washing / dehydrating tank.

[0007]

According to the present invention, by providing an annular rib in the intermediate portion between the inner peripheral surface of the cover and the inner peripheral surface of the balance ring,
The gap between the cover and the balance ring becomes small, and the popping out of the cloth can be suppressed, and the water splash to the upper surface of the balance ring can be suppressed because the water flow cannot cross the annular rib.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the structure of a balance ring of a fully automatic washing machine according to the present invention will be described below with reference to the drawings.

FIG. 1 shows a vertical cross section of a fully automatic washing machine. An outer tub 4 is suspended inside a fully automatic washing machine outer frame 1 via suspension rods 2 and springs 3. Inside the outer tub 4, a washing / dehydrating tub 6 in which a pulsator 5 is mounted at the bottom is disposed. A motor 10 for rotating the washing / dehydrating tub 6 and the pulsator 5 through a clutch 7, a pulley 8 and a belt 9 for switching between a washing operation and a dehydrating operation and stopping a brake is attached to a lower portion of the washing / dehydrating tub 6. Has been done. On the other hand, a top cover 11 is fixed to the upper portion of the outer frame 1, and a power switch and an operating section are mounted inside the top cover 11. A drain valve 12 is connected to the bottom of the outer tub 4 to drain the water in the outer tub 4 through a drain hose 13. On the upper part of the washing / dehydrating tub 6 described above, a balance ring 14 in which salt water is enclosed inside the washing / dehydrating tub 6 which suppresses whirling of the washing / dehydrating tub 6 during dewatering when the cloth is deviated, is attached. 14 is covered with a cover 15 attached to the upper part of the outer tub 4. The present invention is a balance ring 1
4 is provided with an annular rib, the function of which will be described next.

FIG. 2 shows the washing machine at the maximum specified capacity.

In the standard course (automatic course), this is the surface of the water level. Reference numeral 16 is an overflow port provided in the outer tub 4, and when the water level in (a) is higher than the overflow port 16, the overflow water is drained through the drain hose 13 through the drain valve 12 via the overflow hose 17. Has become. In the conventional technology, in order to increase the capacity with a compact body size, it is necessary to make the installation area equal to that of the existing one. The height was increased to increase the capacity. At this time, the positions of the cover 15 and the overflow port 16 were also changed at the same time. At this time, although the installation area was the same as before, the problem was that the total height of the main body of the washing machine was high, so the distance from the laundry inlet to the bottom of the washing and dehydrating tub 6 was long. It was mentioned that it was difficult to take out the laundry. The present invention is based on the balance ring 14 described above.
The purpose is to change the height of the washing machine to increase the capacity that has been supported so far by providing an annular rib on the existing balance ring 14, and to make the overall height of the washing machine body the same as before. I am trying. The technical theme of the present invention is popping out of laundry and splashing of water by a stream of water. A specific solution to the problem will be described below.

FIG. 3 shows an embodiment of the present invention as a specific solution. This figure is an enlarged view of the mouth portion in FIG. According to the present invention, the gap between the cover 15 and the balance ring 14 is provided by providing the ring-shaped rib 18 on the upper surface of the balance ring 14 at the midpoint between the balance ring inner peripheral surface 14a and the cover 15 inner peripheral surface 15a. It is possible to keep it low. This can prevent the laundry from being caught between the cover 15 and the balance ring 14 even if the laundry floats on the upper surface of the balance ring 14. In addition, even when the set water level is high and the water flow c rides on the balance ring 14 to cause water splash, the annular rib 18 can prevent the water from splashing and the water splash can be reduced. As a result, the overflow port 16 provided in the outer tub 4 can also be used at the conventional position.

As described above, by providing the ring-shaped rib 18 on the existing balance ring 14, it is possible to increase the capacity without changing the dimensions (width, depth, height) of the washing machine body.

[0014]

According to the present invention, by providing an annular rib on the upper surface of an existing balance ring at an intermediate position between the inner peripheral surface of the balance ring and the inner peripheral surface of the cover, the main dimensions (width, depth) of the washing machine can be obtained. , Height) can be increased without changing the height.
