Description

DETAILED DESCRIPTION OF THE INVENTION B) Industrial Application Field The present invention is a washing machine that rotates rotors J and E provided at the bottom of a washing tub intermittently from side to side at low speed and during the cooking time.
Regarding J machine.

(Row) Conventional technology This type of swamp washing machine has moved away from the previous model that used rotary blades that rotate at high speed for a long period of time to achieve a high cleaning rate. In recent years, clothes have been rotated to prevent damage to clothing as much as possible.The latter example was shown in Japanese Patent Application Laid-Open No. 17390/1983, and is shown in Figures 2 to 5-5. (11 is a washing tank that also serves as a dehydration tank, and its surrounding wall has many dehydration holes +
21i, and a balance ring (3) is attached to the rim of the mouth. A rotary blade (4) is disposed at the center of the bottom of the washing tub (1). Washing tub (11 is the outer tub (5)
), and a washing tank (1
) or rotating the rotor (4)? Drive motor 16H'
A drive machine with a clutch pre-braking device, etc., and a groove (7) are installed, and the outer tank (5) is suspended from the upper part of the machine frame (8) in a vibration-proof manner at a voltage of 91 Vc.

Therefore, the rotating tool (4) is a large-diameter circular bake uD.
i, a substantially triangular prism-shaped protrusion 01) that gradually protrudes from the periphery of this bake (10) toward the center, and a protrusion 01) that protrudes from each vertex of the triangle of this protrusion toward the periphery of the base housing σ. 4J is formed from the fallen feather tl;;l. As is clear from Fig. 4, each blade (iz is curved gently in the same direction (toward the right in the figure) toward the periphery of the base (10) and faces toward the protruding portion 11). α() is approximately 2 times the outer diameter Tdl of the circular base (10), and is IJ? It is determined that the water surface of in is lower than hl in some places. fruit 11 standing (in the example, washing t17

At the top of the upper ge protrusion (111, a substantially triangular prism a: 1 with a smaller diameter is formed at the top. This triangular prism (
As shown in Fig. 5, the slope (θ2) of the side surface of I3) is gentler than that of the upper end of the side surface of the protrusion g (111) (the angle θ1) of the triangular prism with a large diameter below it. So, (02]-12', (θ1)-i.

In the figure ([a)] It is a boss that fits with the top of the kehiro shaft (151),
rotate! A boss (inserted in the field) is provided on the back side of the top.

Rotation jib < (4+ is N elevation 1 (19 Mounting screw aD on top)
It can be attached to the intermediate shaft by tightening.

The rotary blade (4) is rotated alternately left and right, but the number of rotations is 450 (r.p.
m] ~ 720 Cr-p-m) 3 [J
OCr-p1m] or below. The values of the examples are as follows: 180 [r, p, rnJ]. Then, a reversal cycle is created in which the same single round is collected, in which the shot is transmitted for 1 to 2 seconds to the right, paused for 0.5 to j seconds, and transmitted to the left for 1 to 2 seconds, during the set time. I try to repeat it.

In addition, even if the water level in the skin washing tank (11) becomes lower in the central part due to one rotation of the core (4) in this rotor, as shown in FIG. The value will not be lower than ℃.

In such a device, when water is supplied to the washing qd 6J I 1 l and a cloth fc) is put in, and the rotor blade (4) is made to rotate once, the cloth is placed at the bottom of the rotary blade (414) in the same way as the conventionally used rotor blade. A water flow is generated that tries to rotate horizontally, and at the top of the rotor blade, a triangular prism-shaped 1lili with a protrusion Uυ is created.
The force to raise and lower the cloth is given by li and feather σ2. As a result, the cloth sinks toward the rotary blade along the side wall of the washbasin, as shown by the arrow in Figure 2, and then rotates in the horizontal direction as it floats up along the triangular prism-shaped protruding circle. .

In particular, the three blades α2 of the rotor blade are deflected in the same direction (to the right) in a gentle flat curve as shown in Figure 4, so the water flow generated by the two rotations J green + 41 is on the left and right. There is a difference in the amount of water, and when turning to the right, the water flow that lifts the cloth upward becomes stronger. This is because turning to the right applies a stronger force to the water, so it hits the washbasin wall more strongly and the reaction causes the water to rise one level faster. This results in vertical movement of the cloth.

Since the protruding part (111) is below the water surface, the cloth that has floated up will easily climb over the protruding part and cause a large movement. Since the protrusion is shaped like a triangular prism, the protrusion generates a water flow that chases the cloth around, thereby preventing the cloth from getting entangled in the protrusion.

Particularly in this case, since the top of the protrusion (11) is formed with a top substantially triangular prism αJ with a diameter one step smaller, the top end of the large diameter protrusion aυ and the small diameter top substantially triangular prism (t31) are formed at the top of the protrusion (11). As a result, turbulence is generated in this area, causing the cloth to become more entangled in this area, and the protruding part (
The inclination angle (θ1) of the upper end of the side surface of 111 is approximately triangular prism ([
Since the side inclination angle (θ2) is 31, it becomes easier for the cloth to get over the stopper of rotation R (4).

As described above, in the conventional example, since the cloth is not easily tangled, there is little damage to the cloth due to the tangle, and since the rotation speed of the rotary blade (4) is low, there is little damage to the cloth.

In such a conventional example, the lower part of the rotor blade (4) rotates the clothing in the horizontal direction, and the upper part moves the clothing up and down, and the entire clothing is moved vertically.
4) Since the rotation speed is very low, it is difficult to move the clothes up and down from the beginning of the set time. Therefore, the user may feel that the clothes do not move well and cannot be washed.

Therefore, the rotation time of rotation R(4) is varied.

Alternatively, it has been considered to change the length of the pause time6 to give pulsation to the water flow that is formed, thereby invigorating the movement of the clothing. However, in this case, the motor fi driving the rotation j13+41
5) No θh at 11, the engine stops and the startup sound becomes harsh.

Problems to be Solved by the Invention The present invention aims to fully activate the movement of clothing and at the same time keep the intervals between rotation and rest of the rotor blade constant, thereby preventing the generation of unpleasant noises.

(b) Means for resolving the problem The means for solving the problem of the present invention is to make the single period consisting of the rotation time and rest time of one transmission the same, and to make it uniform between the counterclockwise rotation and the clockwise rotation. It is provided with an inverted cycle t- that increases or decreases the number of consecutive cycles.

(e) Effect: As the number of continuous water flows changes between right and left, the strength of the right- and left-rotating water flows changes, forming a so-called pulsating flow. Therefore, the movement of the clothes becomes active due to this pulsating flow, while the interval between the rotation and rest of the rotor blades remains constant regardless of whether the rotation is on the left or right side. It is the same as that of the conventional example shown in FIGS. Specifically, the rotation speed is about 18 Or, p, m, and the rotation time is intermittently rotated left and right for a maximum of 2 seconds with an appropriate rest time in between.

In the fully automatic course, as before, g Water - Washing - Drainage - Intermediate dehydration - Water supply - M1 Susuki → Drainage - Intermediate dehydration - Water supply → g
2 Susuki → Drainage - Execute the final dewatering process Jr.
Wash with this circle, 1st. The rotor is intermittently reversed during each step of the second rinse. The required times for the washing process, the first rinsing process, the second rinsing process, and the intermediate and final dehydration processes can be freely set in advance.

The rotation α (4) of the reversing vehicle 5c during each washing and rinsing process is shown in FIG. Here, the rotation time is, for example, 1.0 seconds, the rest time is 0.4 seconds, and the single period of rotation stopping is the same. And single period (TR) for clockwise rotation
followed by 1 piece, 4 single period (TL) for left rotation, 2 pieces of (TR), 6 pieces of (TL), 3 pieces of (TR), (
TL) is 2 pieces, (TR) is 4 pieces, (TL ) is 1 piece, (
TR) is 3 pieces.

Two (Tt,), two (TR), and three (TL) follow in this order. That is, the number of successive single periods of left and right rotation increases and decreases, and also increases and decreases at a constant period, so that when one increases, the other decreases, and when one decreases, the other increases.

During this reversal cycle, the strength of the water flow formed by the rotary blade (4) changes from side to side, resulting in a so-called pulsating flow.

Therefore, since the clothes move actively, the cleaning power is improved both in appearance and in reality. The starting and stopping sounds of the motor (6) that fully drives the rotary blade (4) occur regularly because all single cycles are the same.

In addition, since the number of single cycles for clockwise rotation and that for counterclockwise rotation are the same in Nycle, the rotation/transmission force on either the left or right side will not be disproportionately strong, and therefore the tip of the clothing will There is little unevenness.

(G) Effects of the Invention According to the present invention, the movement of the clothes is activated to completely improve the cleaning performance, and irregular start-up and stop noises can be prevented. Therefore, it is extremely high performance and can provide a 1m b-9 rinse machine.
