Then, after rotating to the right for 1 second to 2 seconds, pausing for 0.5 seconds to 1 second, and rotating to the left for 1 second to 2 seconds, the reversal cycle is repeated for a set time. ing. Also, during this rotation, the water surface in the washing machine II (1) is raised to 1 as shown by the dashed line in Fig. 3 due to the rotation of the rotation R (4).
Even if the central part becomes lower in a tree-like manner, the value does not become lower than the above-mentioned protruding part 11).

In such a washing machine, when water is supplied to the washing tub (1) and a cloth (C) is put therein, and the rotor H (4) is rotated, the cloth is stored at the lower part of the rotor blade (4) in the same way as with conventional rotary blades that have been used up. This creates a water flow that tries to rotate the rotor in the horizontal direction, and at the top of the rotor blade, L
It gives the force that makes the cloth rise and fall. As a result, the cloth temporarily sinks toward the rotor along the side wall of the washing tub, as shown by the arrow in Figure 2, and then floats up along the triangular prism-shaped protrusion (11) in the horizontal direction. Rotate.

In particular, the three blades (12〉) of the rotor blade are deflected in a gentle curve in the same direction (rightward) as shown in Figure 4, so the water flow generated by the rotation of the rotor blade (4〉) There is a difference between the clockwise rotation and the water flow, which lifts the cloth upwards.This is because clockwise rotation applies a stronger force to the water, so it hits the washing tub wall more strongly and the reaction is due to the reaction. This creates a floating water flow, which causes the fabric to move up and down.

Since the protrusion (11) is placed below the water surface, the cloth that has floated up can easily climb over the protrusion (11), resulting in a large movement. At this time, the protrusion (11
) is not cylindrical but triangular prism-shaped, so this protrusion generates a stream of water that tries to drive the cloth around, preventing the cloth from getting entangled in the protrusion.

Particularly in this case, at the top of the protrusion (11), a substantially triangular prism (13) with a smaller diameter has been formed, so that the upper end of the protrusion (11) with a larger diameter and the substantially triangular prism (13) with a smaller diameter The triangular prism (13) generates turbulent flow in this area, and the cloth is drawn from one side to this part, and the inclination angle (θ1) of the upper end of the side surface of the protrusion (1) is Approximately triangular prism (13 inches) Side inclination angle (θ2 inches),
It becomes easier for the cloth to get over the rotor blade (4).

このように従来例は、洗たく中に衣類がからみ付きにく
いので、からみ付きによる布傷みも少なく、回転翼(4

In this way, in the conventional example, clothes are less likely to get tangled during washing, so there is less damage to the cloth due to tangles, and the rotary blade (4
) Since the rotation speed is low, there is little damage to the fabric.

In this conventional example, when gently washing underwear, the time for each left and right rotation is shortened. However, since the rotational speed of the rotary blade (4) is very low, the movement of the clothes is noticeably reduced, especially in the case of soft washing, and even though it is soft washing, it is sometimes difficult to tell whether the clothes are being washed or not.

(ハ)発明が解決しようとする問題点 本発明は、回転時間を短縮してソフト洗いを実行した際

(c) Problems to be Solved by the Invention The present invention is designed to shorten the rotation time so that the movement of clothes can be activated even when soft washing is performed.

(d) Means to solve the problem The feature of the present invention is the reversal cycle of the rotor blade, in which the rotation time in one direction is gradually lengthened or shortened, and then the rotation time in the other direction is gradually shortened or lengthened. I've been spending my time following this.

(e) Effect: By sequentially changing each rotation time, the water flow is made to pulsate, thereby increasing the movement of the clothing. However, since the difference between the left and right rotation times is reduced, violent movements at the transition between left and right rotations can be suppressed, which is compatible with the mode of soft washing. For example, if you match the intermediate value of the changing time to the rotation time of conventional soft washing, the total rotation time will be about the same as before and there will be no difference in cleaning power, but the clothes will move. becomes possible.

In the fully self-exciting course, as before, water supply - training - drainage - intermediate dehydration - water supply - 1st rinse - drainage - intermediate dehydration - water supply - 2nd
A process of rinsing, draining, and final dehydration is performed, and the rotary blades are intermittently reversed during each of the first and second rinsing processes. The times required for the washing process, first rinsing process, second rinsing process, and intermediate and final dehydration processes can be freely set in advance.

The reversal cycle (one cycle) of the rotor blade (4) in the washing process and each rinsing process is shown in Fig. 1 (a), and the change in the intensity of the water flow formed thereby is shown in Fig. 1 (x).Here The reversal cycle is arranged with a constant pause time of 0.2 seconds between left and right rotations, and from the left rotation side to the left 1
2 seconds → right 1.2 seconds - left 10 seconds - right 1.0 seconds → left 08 seconds -
Right 0.8 seconds → Left 0.6 seconds → Right 06 seconds → Left 0.4 seconds - Right 0
.. It changes to 4 seconds, and from here on, it goes the other way, from 0.6 seconds to the left → 0 to the right.
6 seconds - 0.8 seconds on the left Pass 0.8 seconds on the right - 1.0 seconds on the left → 1.0 seconds on the right. O
It changes in seconds. In other words, it is a reversal cycle (one cycle) in which the rotation changes stepwise from the longest to the shortest and then returns stepwise from the shortest to the longest.The rotation time here is the same as the rotation time in the other direction. It is the sum total, and if the rotation time here can be divided, it is the total time.

Thus, when this reversal cycle is repeated during the set time, the generated water flow is initially strong, but gradually weakens, and then gradually becomes stronger, and this change in strength, ie, pulsation, makes the movement of the clothing appear larger.

特に、一方向水流が慣性で残っている、衣類が流動して

上り時に衝突力によって衣類の動きを大きくする。
In particular, when the clothes are flowing and the one-way water flow remains due to inertia, a water flow in the other direction is formed, so that the movement of the clothes is increased by the collision force at the time of the rise.

一方1回転時間の総和は回転時間を0.8秒で固定した
従来のソフト洗いの場合と同一と成り、回転時間の和で
決まるfCb力は同程度と成る。
On the other hand, the total time for one rotation is the same as in the case of conventional soft washing in which the rotation time is fixed at 0.8 seconds, and the fCb force determined by the sum of the rotation times is about the same.

即ち、洗いの強さとしてはソフト洗いと同等であるが、
衣類の動きは大きく見えるように成る。
In other words, the washing strength is equivalent to soft washing, but
The movement of clothing appears larger.

そして、右回転から左回転に代った時の時間差は少いの

衣類が異常に激しく動いてソフト洗いの目的作用を損な
うことはない。
Also, since the time difference when changing from right to left rotation is small, the water flow will not pulsate too much, and the clothes will not move abnormally violently during soft washing, which will impair the purpose of soft washing. .

Note that even if the reversal cycle of this embodiment is changed to one in which the rotation time is from the shortest to the longest and then back to the shortest, similar changes in water flow and movement of clothing occur. Further, the starting rotation direction may be clockwise rotation. Further, the maximum and shortest rotation times can be changed depending on the desired water flow, and the intermediate times can also be changed to obtain stepwise changes.

(G) Effects of the Invention According to the present invention, by synchronizing the left and right rotation time and making the length change, it is possible to generate pulsations in the water flow that are consistent with soft washing, and to make the movement of clothes appear larger during soft washing. Therefore, it is possible to provide a washing machine that can be used with confidence without worrying about the washing effect.
