BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine used for general households or businesses.

[0002]

2. Description of the Related Art Conventionally, washing machines include, for example, a stirring type and a swirling type, and in any of these types, a stirring blade having a plurality of blades is provided at the bottom of a washing tub, and each of them has a predetermined type. It is rotated by rotating it to the left and right for washing, and in this stirring type, the stirring blade is rotated from left to right about 50 to 80 per minute. In the spiral type, the stirring blade is normally rotated at 500 rpm or more to create a strong water flow, and the rotation direction is normally reversed every 30 seconds.

[0003]

However, this agitating type was developed in order to slow the rotating operation to prevent the entanglement and damage of the fabric, and although it is suitable for a large amount of washing, the washing time is long. There is a problem that becomes
The spiral type automatically reverses the rotation direction every 30 seconds in order to prevent the fabric from twisting, but in any of these systems, the fabric is entangled and twisted because the fabric is rotated by the stirring blades. Therefore, the damage to the fabric caused by this was unavoidable.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a washing machine which can be washed without twisting or entanglement of the cloth.

[0005]

In order to solve the above technical problems, the present invention comprises a washing tub that opens upward and a pressing operation frame housed in the washing tub, and the pressing operation frame includes several other pressing operation frames. Four actuating plates having punched holes are pivotally connected to each other in a substantially rectangular shape via hinges, and the adjacent actuating plates are closed and contracted to give water a washing action. Exists in the washing machine.

[0006]

With the above-mentioned structure, the cloth is pressed and washed, and vinegar pieces that eliminate the entanglement are formed, and damage to the cloth can be prevented.

A support wall 3 is formed at a corner portion of the drawing, and a pressing operation frame 4 is housed in the washing tub 2.

The pressing operation frame 4 includes four pressing base plates 5,
6, 7, 8 and each pressing element plate 5, 6, 7,
8 is formed in a substantially rectangular shape, and is also formed in a curved shape on the wall side of the washing tub, and each pressing element plate 5, 6, 7, 8 has a large number of punch holes 9 penetrating at a predetermined interval. The punching holes 9 of each of the pressing element plates 5, 6, 7, and 8 are provided so that the entire area is smaller than the plate surface portion. Hinge portions 10a, 10b, 10c, 10d are formed on the left and right adjacent edges of the pressing element plates 5, 6, 7, 8 formed in this way through hinge pins 11a, 11b, 11c, 11d. A pressing operation frame 4 having a substantially rectangular shape is formed, and sliding rods 12a, 12b, 12 having a predetermined length are provided at substantially central height positions of the hinge portions 10a, 10b, 10c, 10d of the pressing operation frame 4.
c and 12d are mounted horizontally, and the sliding rods 12a, 12b, 12c and 12d are provided at predetermined positions of the respective support walls 3 in the washing tub 2 so that they can slide in a watertight manner on the sliding receiving portion 13. The pressing operation frame 4 is supported by being inserted.

As described above, the sliding rods 12a and 12c and the hinge portion 1 of the pressing operation frame 4 installed inside the washing tub 2 face each other.
0a and 10c, the sliding rods 12b and 12d, and the hinge portions 10b and 10d are provided so as to be alternately opposed to each other along the diagonal lines a and b of the washing tub 1 as illustrated.

The sliding rods 12a and 12c, the hinge portions 10a and 10c, and the sliding rods 12b and 12d and the hinge portions 10b and 10d, which are opposed to each other, of the pressing operation frame 4 are diagonal lines a of the washing tub 2 as shown in the drawing. , B, an appropriate actuating means is selected as the actuating means that alternately move in opposition to each other. For example, an actuating cylinder (not shown) is provided at the end of one of the sliding rods, for example, the sliding rod 12a. When the slide rods 12a are extended and actuated, the sliding rod 12a advances along the diagonal line a, whereby the hinge portion 1 is moved as shown in FIG. 3 (c).
The pressing element plates 5 and 8 on both sides of 0a are opened and expanded as shown in the drawing, and in conjunction with this, the hinge portions 10b and 1 on the diagonal line b are interlocked.
The sliding rods 12b and 12d are retracted through 0d, and the pressing element plates 6 and 7 connected to the hinge portions 10b and 10d.
Is expanded and the hinge portion 10c and the sliding rod 12c on the diagonal line a are moved to face the sliding rod 12a. Further, when the actuating cylinder is shortened, it is actuated in the opposite manner to the above. In short, the sliding rods 12a and 12c and the hinge portions 10a and 10c, the sliding rods 12b and 12d and the hinge portions 10b and 10d are shown in the drawing. As described above, any operating means may be used so as to alternately move oppositely along the diagonal lines a and b of the washing tub 1.

Next, the operation of the washing machine 1 having the above structure will be described. First, water is poured into the washing tub 2 to a predetermined water level, the cloth to be washed is put in the pressing operation frame 4, and the detergent is put therein. Thereafter, when the actuating means is actuated, as described above, for example, when the sliding rod 12a advances along the diagonal line a, as shown in FIG.
The pressing blanks 5 and 8 on both sides of a are opened and expanded as shown in the figure, and in conjunction with this, the sliding rods 12b and 12d are retracted through the hinges 10b and 10d on the diagonal line b, and the hinges 10b are retracted. , 10d connected to the pressing element plates 6 and 7 are expanded to open the hinge portion 10c and the sliding rod 12 on the diagonal line a.
c is moved to face the sliding rod 12a, and the left and right pressing element plates 5 and 6 and the pressing element plates 7 and 8 with the hinge portions 10b and 10d as fulcrums are closed and contracted. When the pressing element plates 5, 6 and the pressing element plates 7, 8 are closed and contracted, the entire area of the punch holes 9 penetrating the respective element plates 5, 6, 7, 8 is smaller than the plate surface. Therefore, a part of the water in the pressing operation frame 4 flows out from the punch hole 9, but the remaining water acts to press the cloth in the frame 4 from the left and right, which is a kind of pressing. It becomes a washing action.

Then, the sliding rod 12a on the diagonal line a,
When 12c is retracted, the sliding rod 12 on the diagonal line b
b and 12d are moved forward, the sliding rods 12a and 12c
The left and right blanks 5 with the hinges 10a and 10c of
8 and the blank plates 6 and 7 are closed and contracted, and the cloth is also pressed and washed by this closed and contraction operation, and diagonal lines a and b intersect at the initial stage of the sliding lots 12a and 12c retracting. As shown in Fig. 3 (b), the fabric near the center position is moved in the left-right direction along the diagonal line a from the same center and is washed by the closing operation of the blanks 5, 8 and the blanks 6, 7. It
Thereafter, the blank plates 5, 6, 7, 8 are alternately closed and closed as described above, and the cloth is pressed and washed.

The sliding rods 12a, 12b, 12c, 12d arranged on the diagonal lines a, b in this manner have the pressing elements 5, 6, 7, 8 attached to the tips of the sliding rods 12a, 12b, 12c, 12d via the hinge portions 10a, 10b, 10c, 10d. The sliding rods 12a, 12b, 12c, 12d on the diagonals a, b are provided so as to be alternately opposed to each other by alternately closing and sliding the adjacent pressing element plates 5, 6, 7, 8 into water. Since the fabric is washed by pushing and washing it, there is no entanglement in the fabric, the damage can be eliminated, and the fabric can be gently washed. It will be possible.

Next, FIG. 4 shows another embodiment, and only the pressing operation frame 14 is illustrated. This pressing operation frame 14 is similar to the pressing operation frame 4 described above in that the pressing element plates 5, 6,
7, 8 are hinged by hinge pins 11a, 11b, 11c, 11d to form hinge portions 10a, 10b, 10c, 10
d is formed, of which, for example, the hinge pin 11c on the diagonal line a is fixed to the washing tub side, and the sliding rod 12a is attached to the hinge portion 10a on the diagonal line a to operate the sliding rod 12a. While connected to the means,
The hinge portions 10b and 10d are configured in a free state. Therefore, when the operating rod 12a is moved forward, as shown in FIG. 4 (c), the pressing element plates 5 and 6 and the pressing element plates 7 and 8 are closed and contracted and retracted as in the pressing operation frame 4. Then, as shown in FIG. 4 (a), the pressing element plates 5 and 8 and the pressing element plates 6 and 7 are closed and contracted to give a washing operation to the water, and the same effect as the pressing operation frame 4 is obtained. It plays. In addition, in the case of the pressing operation frame 14, FIG.
As shown in (d), the hinge portion 10a is linearly reciprocated along the diagonal line a, and the hinge portions 10b and 10d are moved along curved locus lines P1 and P2 as shown in the figure. Therefore, as shown in the drawing, the washing tub 2A can be formed into a bottomed cylindrical shape having a substantially triangular cross section, and a novel design beauty that has not been available can be exhibited.
