EMBODIMENT OF THE INVENTION Hereinafter, the Example of this invention is described, referring drawings. In addition, the thing with the same structure as a conventional example attaches | subjects the same code | symbol, and abbreviate | omits description.

Example 1

As shown in Figs. 1 and 2, the circulating water passage 16 is contained in the guide wall portion 17, and the fluid from the pump chamber 14 formed on the outer circumference of the rear wing 13 of the pulsator 2 is shown. It is formed to the lower part of the balancer 4. The guide wall portion 17 is formed by extending the substantially L-shaped portion 17b so as to form a discharge port 18 between the front wall upper end portion 17a and the upper wall upper end portion 17a. The substantially circular arc shape protruding the front wall upper end portion 17a upwards. Formed. Here, the distance between the front wall upper end part 17a and the substantially L-shaped part 17b in the discharge port 18 is S = 4-10mm in the center part, T = 6-12mm in both ends, and it is comprised so that TS> 2. have.

The operation in the above configuration will be described. After the clothes and the detergent are put into the washing tank 1, the water is supplied to a predetermined level, and the reverse side of the pulsator 2 is inverted in synchronization with the rotation of the pulsator 2. Washing water passes from the pump chamber 14 formed on the outer circumference of the rear wing 13 to the circulation water channel 16, and the discharge port 18 between the front wall upper end portion 17a of the guide wall portion 17 and the substantially L-shaped portion 17b. ) Is discharged into the washing tank 1.

Here, since the discharge port 18 becomes larger as the distance between the substantially L-shaped portion 17b of the front wall upper end portion 17a goes from the center portion to the both end portions (S < T), the water level in the washing tank 1 is low, and the circulation water passage When the quantity of wash water pumped up and discharged above (16) is relatively small and the discharge pressure is also low, when the mainstream at the center of the circulation channel 16 reaches the front wall upper end portion 17a, the discharge port 18 Disperse from the center of the to both ends. For this reason, the flowing water of the washing water discharged from the discharge port 18 becomes wide, and the washing water can be sprayed uniformly over a wide range while ensuring the shape of the rough liquor, and the cleaning stain is reduced to improve the cleaning performance. You can.

Example 2

As shown in FIG. 3, the circulation water channel 19 is arrange | positioned on the substantially diagonal of the washing tank 1, and each circulation water channel 19 is contained in the guide wall part 20. As shown in FIG. The guide wall portion 20 extends to substantially the L-shaped portion 20b toward the rear wall upper end portion so as to form the discharge port 21 between the front wall upper end portion 20a. This substantially L-shaped portion 20b has an upward angle W of 5 ° to 15 ° with respect to the horizontal direction. The front wall upper end 20a is formed in the substantially circular arc shape which protruded upwards. Other configurations are the same as those of the first embodiment.

The operation in the above configuration will be described. After the clothes and the detergent are put into the washing tank 1, the water is supplied to a predetermined water level, and the reverse side of the pulsator 2 is inverted in synchronization with the rotation of the pulsator 2. Washing water flows from the pump chamber 14 formed on the outer circumference of the rear wing 13 to the circulation water channel 19, and the discharge port 21 between the front wall upper end portion 20a of the guide wall portion 20 and the substantially L-shaped portion 20b. ) Is discharged into the washing tank 1.

On the other hand, when the water level in the washing tank 1 is low, the number of washing water pumped up and discharged above the circulation water passage 19 is small in quantity, the discharge pressure is low, and the reach D of the washing water is shortened. In this case, when the upward angle W of the guide wall portion 20 in the horizontal direction of the substantially L-shaped portion 20b is increased, as shown in FIG. 4, the arrival distance D of the washing water discharged from the discharge port 21 is increased. .

In the present embodiment, since the substantially L-shaped portion 20b has an upward angle W of 5 ° or more with respect to the horizontal direction, the washing water discharged from the discharge port 21 can be reached near the center d of the washing tank 1. Moreover, since the circulation water channel 19 is arrange | positioned on the substantially diagonal of the washing tank 1, and is formed in the substantially circular arc shape which protruded the front wall upper end part 20a upward, over the whole surface of the washing tank 1, It is possible to spray the washing water evenly over a wide range.

Next, when the water level in the washing tank 1 is high water level P1 and there are few clothes, the washing water pumped up and discharged above the circulation water passage 19 has a large quantity and a high discharge pressure, so that it is linear in the horizontal direction. It becomes easy to discharge. Here, when the upward angle W in the horizontal direction of the approximately L-shaped portion 20b of the guide wall portion 20 is increased, the reach D of the washing water discharged from the discharge port 21 becomes long, so that the washing tank 1 is approximately The washing water discharged from the discharge port 21 on a diagonal line collides with each other substantially above the water surface, and the scattering amount F of the washing water out of the washing tank 1 increases as shown in FIG.

In this embodiment, since the upward angle W of the L-shaped portion 20b is set to 15 degrees or less with respect to the horizontal direction, the discharged washing water forms a free surface 22 in a dome shape, respectively, Before colliding near the surface of water or colliding with each other, they fall directly to the surface of the water, and the amount of scattered washing water out of the washing tank 1 becomes f as shown in FIG. 5 to suppress the scattering of detergent and foam. .

Example 3

As shown in Figs. 6 and 7, the circulation channel 23 is contained in the guide wall 24, and the guide wall 24 is discharged from the upper wall 24a to the upper wall 24 of the rear wall. The L-shaped part 24b is extended and formed so that 25 may be formed. This substantially L-shaped part 24b covers the front wall upper end part 24a from the upper side in the radial direction and the radial direction bidirectionally, and makes it into a convex shape toward the center direction of the washing tank 1, and the edge part 24c is a mother-side part 24c. It's coming off.

Moreover, the rib 24b is formed in the substantially upper surface of the L-shaped part 24b, and is fitted with the lower part of the fluid balancer 4. As shown in FIG. Here, the approximately L-shaped portion 24b is formed at a position lower than the lower surface of the fluid balancing device 4 such that the step Y between the lower surface front end of the L-shaped portion 24b and the lower surface Y of the balancing device 4 is Y≥0. It is. The other configuration is the same as that of the first embodiment.

The operation in the above configuration will be described. After the clothes and the detergent are put into the washing tank 1, the water is supplied to a predetermined water level, and the reverse side of the pulsator 2 is inverted in synchronization with the rotation of the pulsator 2. Washing water passes from the pump chamber 14 formed on the outer circumference of the rear wing 13 to the circulation water channel 23, and the discharge port 25 between the front wall upper end portion 24a of the guide wall portion 24 and the substantially L-shaped portion 24b. ) Is discharged into the washing tank 1.

At this time, the wash water passes from the circulation water passage 23 through the upper wall upper end portion 24a of the guide wall portion 24 and immediately collides with the lower surface of the L-shaped portion 24b, and at the same time the discharge pressure and the viscosity of the wash water ( While being guided to the substantially L-shaped portion 24b as it is, it does not interfere with the lower surface of the fluid balancer 4, but forms and discharges an oil-shaped shape 26 having an approximately curved portion with an end spreading.

Therefore, in the case of washing a lot of bulky clothes, since the volume becomes large, the washing water can be sprinkled from the circumferential end of the washing tank 1 to the whole surface of the washing tank 1, promoting the dissolution of the detergent and improving the washing performance. At the same time, a portion where the discharged washing water is sprinkled on the clothes and a portion which is not sown can be generated, thereby preventing the cleaning stains generated. In addition, it is possible to promote the submersion of the clothing and to prevent the clothing from jumping out of the washing tank 1.

In addition, in this embodiment, although one case of the circulation water channel 23 is demonstrated, if a plurality of circulation water channels 23 are formed in the washing tank 1, it goes without saying that an effect increases further.

According to the first invention of the present invention as described above, a circulating water that is pumped toward the side wall of the washing tank from the washing chamber and the pulsator disposed rotatably at the bottom of the washing tank, and the pump chamber formed on the rear side of the pulsator. Since the guide wall portion is formed to extend substantially L-shape so as to form a discharge port between the upper wall upper end portion and the upper wall upper end portion thereof, the guide wall portion is formed in a substantially arc shape protruding upward the upper wall upper portion, Water discharged from the discharge port above the circulating water path can distribute the mainstream forces from both ends of the discharge port to both ends, so that the amount of discharged water can be sprayed at least in a wide range and uniformly, reducing washing spots. And the cleaning performance can be improved.

Further, according to the second invention of the present invention, since the substantially L-shaped portion is inclined upward with respect to the horizontal direction, and the discharge port is formed between the upper end portion of the substantially arc-shaped front wall, the water level of the washing water in the washing tank is low, and the discharge is performed. Even when the quantity is small, the washing water discharged from the discharge port can be reached near the center of the washing tank, and since the upper wall upper part is formed in an approximately arc-shaped shape projecting upward, the washing water can be sprayed widely and widely. Can be. In addition, by suppressing the upward inclination of the substantially L-shaped portion, when a plurality of discharge ports exist on a substantially diagonal line of the washing tank, and the quantity of discharged is relatively large, detergent generated by collision of washing water discharged from the plurality of discharge ports with each other, The scattering of bubbles can be suppressed.

In addition, according to the third invention of the present invention, the substantially L-shaped portion covers the upper end of the front wall of the guide wall portion from the upper side in the radial direction and the radial direction at the same time, and is shaped into a flat fan toward the center direction of the washing tank. As it rises a channel and is discharged in the shape of an approximately flat fan along the lower surface of the upper approximately L-shaped part, it pulses from the inner peripheral part of the washing tank irrespective of the movement of clothes such as the case of washing a lot of bulky clothes Whenever the reversal of the data is possible, the washing water can be sprayed on the clothes in the washing tank without staining, and the discharged washing water is sprinkled on the clothes to prevent the cleaning stains from occurring. .
