Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a washing machine, and more particularly, it can wash white socks with mud stains; No need to wash your hands to remove stubborn stains that cannot be removed with regular washing.

Concerning a washing machine that can be cleaned thoroughly.

[Conventional technology]

When washing is performed using a washing machine, the amount of clothes to be washed is approximately proportional to the amount of water put into the washing tank, and the clothes are circulated in the washing tank according to the water flow generated by the stirring blade. It often gets separated from the stirring blades.

The mechanical force acting on the clothing is reduced compared to the mechanical force inherent in the stirring blade itself.

However, when washing with a washing machine, it is possible to remove normal light dirt and easy-to-remove dirt relatively easily, but the biggest worry for housewives who are involved in daily washing is the amount of items to be washed. Small but stubborn stains, such as mud stains on the toes and heels of white socks 1
This is for cleaning stubborn stains such as mud and oil stains on work gloves and upper and lower coveralls for work gloves.

On the other hand, when washing with conventional washing machines, it is often experienced that it is not possible to wash colored items and white items at the same time. You must wash one-color items and white items at different times.

Washing requires a lot of time.

In consideration of the above points, the present applicant first proposed that
As shown in Japanese Patent No. 58195, a washing machine was proposed in which a mini washing tank was detachably attached to the upper space of the washing tank.

Then, if you put stubbornly soiled items such as muddy white socks into the mini-washing tank and wash them, these stubborn stains will be removed by stirring inside the mini-washing tank. By making contact with a relatively large number of blades and receiving their mechanical action, the dirt removal effect can be improved compared to the case where stubborn dirt is washed using a commonly used washing machine. At this time, if you put lightly soiled items or easily removed items into the washing tank located at the bottom of the mini washing tank, you can wash stubbornly dirty items and normal dirty items for the same amount of time. can do.

In addition, if colored (or white) items are placed in the mini washing tank, and white items (or colored items) are placed in the washing tank located at the bottom of the mini washing tank, You can wash colored items and white items for one hour at the same time, reducing the amount of time required to wash them, and helping families busy with housework and childcare. This is convenient for housewives.

The advantages of a washing machine that has a removable mini-washing tank in the upper space of the washing tank are as described above, but it is also possible to put stubbornly soiled items such as muddy white socks into the mini-washing tank and wash them. When this method is used, no special measures are taken to force these stubborn stains into contact with the stirring blades and receive the mechanical force of the stirring blades, so this method is more effective at removing stubborn stains than conventional methods. However, there is a limit to its effectiveness in removing dirt.

On the other hand, during the rotation of the stirring blade in the mini washing tank,
In order to ensure that stubborn dirt always comes into contact with the stirring blades and receives its mechanical action, it is considered to install a restraining plate inside the mini-washing tank to press the washing up and down.Specifically, Roughly speaking, a plurality of protrusions or recesses are provided in the height direction on the wall of the mini washing tank, and depending on the amount to be washed, an appropriate one is selected from among the plurality of protrusions or recesses. Alternatively, the holding plate for vertically moving and pressing the object to be washed is fixedly locked in the recess.

[Problem to be solved by the invention]

However, a plurality of protrusions or recesses are provided in the height direction of the tank wall in the mini washing tank, and an appropriate one is selected from among the plurality of protrusions or recesses depending on the amount to be washed. If only a holding plate for vertical movement of the items to be washed is fixedly fixed in the recess, it may lack careful consideration for the items to be washed.For example, when the amount of items to be washed is relatively small, The mechanical force of the stirring blades does not act sufficiently on the washing material, causing the items to be washed to float and move around in the water. Even if a play cloth is added, stubborn dirt that is intended to be washed often ends up getting into the play cloth. It cannot be denied that the acting force becomes insufficient and the stain removal effect is impaired.

On the other hand, contrary to the above, for the inside of the mini washing tank.

If you put in more items to be washed than the specified amount, the washing motor may lock up due to the excessive frictional force between the holding plate for vertically moving the items to be washed and the stirring blade, and the fabric will be damaged prematurely. There are also problems.

The present invention has been made in consideration of the above points, and includes:
For example, the purpose of this is to
Mud and oil stains on work gloves, upper and lower coveralls for work mortars, etc.
A washing machine that can remove stubborn dirt that cannot be removed with regular washing without having to wash it by hand.
In particular, even if the amount of stubborn dirt to be washed is relatively small, the mechanical force of the stirring blades can be reduced by keeping the items to be washed in constant contact with the stirring blades without requiring a play cloth as in the past. It fully acts on the items to be washed, increasing the stain removal effect compared to conventional methods, and on the other hand, even if there are more stubborn stains than the specified amount, it can be used with a conventional holding plate for vertically pressing the items to be washed and stirring. To provide a washing machine which is excellent in ease of use and avoids excessive friction with the blades, prevents the washing motor from locking up and prevents fabric damage from progressing at an early stage.

[Means to solve the problem]

The object is to provide a washing machine having a stirring blade rotatably supported on the bottom of the washing tank, and a restraining member for vertically pressing the laundry object, which is removably attached above the stirring blade and facing the stirring blade. This is achieved by providing means for elastically pressing the holding plate against the items to be washed in the washing tank.

[Effect]

According to the present invention having the above-mentioned configuration, the holding plate for vertically pressing the washing object, which faces the stirring blade rotatably supported at the bottom of the washing tank, is always attached downwardly via the elastic body. Even if the amount of stubborn dirt is relatively small, the item to be washed can be kept in constant contact with the stirring blades without the need for a play cloth like in the past. By applying the mechanical force of the stirring blades to the items to be washed, the dirt removal effect can be improved more than ever.

On the other hand, according to the present invention having the above configuration, even if the amount of stubborn dirt to be washed is more than the specified amount, one elastic body can
Since it contracts and retreats according to the amount, it is possible to avoid excessive friction between the holding plate for vertically moving and pressing the washing object and the stirring blade, as in the conventional case, and prevent locking of the washing motor and early progress of damage to the fabric.
