In the pool rinsing, after a predetermined amount of water is injected into the washing and dewatering tank, the water injection is stopped, and the rotating blades are rotated to perform the rinsing. In the water-injection rinse, the water injection is continued even after a predetermined amount of water is injected into the washing and dewatering tub, and the rinsing is performed by rotating the rotary blades while discharging a part of the water in the washing and dewatering tub. On the other hand, in the dehydration rinse, first, water is injected to the extent that water permeates the entire laundry, and after the injection is stopped, the washing and dewatering tub is rotated at a high speed to perform dehydration. In this dehydration rinsing, since the detergent that has permeated into the laundry is blown away with water by the dehydration and quickly removed, it is possible to obtain sufficient rinsing performance with a smaller amount of water compared to pool rinsing and water rinsing. it can.

る。Means for Solving the Problems and Embodiments of the Invention
The present invention has been made to solve the above-described problems. The present invention provides a water injection step in which water is applied to laundry after washing, which is housed in a washing and dewatering tank housed in an outer tub, and a washing step after the water injection step. In a washing machine that performs a dehydration rinsing that includes a dehydration step of rotating a dewatering tub at a high speed and scattering a detergent component together with water, a) water intake for taking in water poured into the washing and dewatering tub from the bottom of the outer tub. B) a circulating water supply passage connected to the water intake opening and connected to a water supply opening above the washing and dewatering tub; c) provided in the middle of the circulation water supply passage and taken in from the water intake opening during the dewatering / rinsing water injection process. And forced circulation means for discharging the discharged water from the water supply opening.

を促進することができる。[0006] In the washing machine according to the present invention, for example, a pump can be used as the forced circulation means. At the time of a water injection process at the time of dehydration and rinsing, first, tap water (or water supplied from the outside such as bath water) is injected from a water injection port provided above the washing and dewatering tub. Then, the pump is driven after an appropriate amount of water has accumulated in the washing / dewatering tub. The water that has accumulated in the outer tank is drawn in from the intake by the pump,
The water is discharged from the water supply opening into the washing and dewatering tank through the circulation water supply channel. The discharged water falls on the laundry, and the water returned to the outer tub is used for recirculation. Therefore, even if the injection of water from the water inlet is stopped after the appropriate amount of tap water is once injected, the water accumulated in the outer tub is repeatedly used to descend from the top of the laundry and penetrate into the laundry. Leaching of detergent can be promoted.

材、例えば外槽カバーに設ける構成とするとよい。In the above washing machine, it is preferable that the water supply opening is provided separately from a water supply port for supplying tap water during dehydration and rinsing. In addition, it is preferable to stably fix the water supply opening above the washing and dewatering tub so that the water circulated to an appropriate location in the washing and dewatering tub can be dropped off. May be provided on an outer tank or a member fixed to the outer tank, for example, an outer tank cover.

に伴い洗濯物全体にほぼ均一に水が降りかかる。[0008] Furthermore, since the entire laundry is not sufficiently immersed in water in the dehydration rinsing, in order to prevent uneven rinsing, it is necessary to pour water on the laundry in the washing and dehydrating tub as uniformly as possible during the pouring process. Is preferred. Therefore, if the washing and dewatering tub is slowly rotated with the drain valve for discharging the water injected into the washing and dewatering tub during the water injection process, tap water and water supply drops falling from the water injection port can be used. Even if the circulating water falling from the tub reaches only a predetermined range in the washing and dewatering tub, water falls almost uniformly on the entire laundry as the washing and dewatering tub rotates.

る。Also, as described above, the washing and dewatering tub is not rotated during the pouring process of the dewatering and rinsing, and the water discharged from the water supply opening is allowed to fall from almost the entire circumference of the washing and dewatering tub. Unevenness can be prevented.

物に水を効果的に降りかけることができる。Specifically, for example, a water conduit is formed on an outer tub cover attached to the inner periphery of the upper edge of the outer tub along a substantially circular opening of the washing and dewatering tub, and an appropriate portion of the water conduit is formed. Alternatively, if the water supply opening is provided on substantially the entire circumference, it is possible to pour water on the laundry from substantially the entire circumference of the washing and dewatering tub. With such a structure, after the spin-drying, water can be effectively poured on the laundry that has solidified in the vicinity of the inner peripheral wall of the washing and dewatering tub or is stuck to the inner peripheral wall.

ぎ性能を向上させることができる。According to the washing machine of the present invention, the water injected into the washing and dewatering tub circulates and repeatedly falls on the laundry. Normally, the dirt of the water accumulated in the outer tub after falling once on the laundry during the water injection process of the dehydration and rinsing is small, so by repeatedly using this water, the detergent that has penetrated into the laundry can be removed from the laundry. It has a sufficient effect to exude. Therefore, even if the amount of tap water to be used is reduced, it is possible to secure the same rinsing performance as the conventional one. If the same amount of tap water as the conventional one is used, the rinsing performance can be improved.

濯物に降りかかる。The processing operation during dehydration and rinsing, which is a feature of the washing machine of the present invention, will be described below with reference to the flowchart of FIG. At the start of the dehydration rinse, the laundry is usually in a state of sticking to the inner peripheral wall of the washing and dewatering tub 3 by the immediately preceding dehydration (for example, intermediate dehydration for removing the detergent water used for washing). ing. When the dehydration rinsing is started, first, the drain valve 16 is closed (step S1), while the water supply valve 12 is opened (step S1).
2). As a result, tap water flows out of the water inlet 14 and falls on the laundry.

水が徐々に洗濯兼脱水槽３の底部に溜まってゆく。Next, the control unit 30 turns on / off the motor 7, for example, so that the washing and dewatering tub 3 is rotated at a low speed.
A control signal for repeating the control at a cycle of 1 second / 4 seconds is sent to the motor drive unit 33 (step S3). As a result, the washing and spin-drying tub 3 rotates slowly, and the laundry sequentially moves at a position where water from the water inlet 14 falls with the rotation. It takes. The water that has fallen on the laundry oozes into the laundry while leaching out the detergent remaining in the laundry, and the water containing this detergent gradually accumulates at the bottom of the washing and dewatering tub 3.

水に滲出する。If one minute has elapsed after the start of the rotation of the motor 7 (step S4), the water supply valve 12 is closed to stop water injection from the water inlet 14 (step S4).
5). At this time, the washing and dewatering tub 3 is filled with water enough to at least soak the lower part of the laundry. Subsequently, the controller 30 sends a control signal to the pump driver 35 to drive the pump 19 (step S6). When the pump 19 is driven, the water sucked from the outer tub 2 through the water intake port 18 rises in the circulation water supply passage 20 and blows out from the discharge port 21 to the washing and dewatering tub 3. At this time, the direction in which water blows out is discharge port 2.
Although depending on the shape of the pump 1 and the suction capacity of the pump 19, for example, as shown in FIG. Keep it. Since the washing and dewatering tub 3 keeps rotating slowly, the water blown out from the discharge port 21 sequentially falls on the laundry stuck around the entire inner wall of the washing and dewatering tub 3. For this reason, the laundry is easily peeled off from the inner peripheral wall of the washing and dewatering tub 3, and the detergent that has permeated the laundry oozes out into the water.

Then, the motor 7 is turned off to stop the rotation of the washing and dewatering tub 3 (step S9). Further, the drain valve 16 is opened to discharge the water accumulated in the outer tub 2 to the outside through the drain hose 17 (step S10).

得られる。Since it is difficult to obtain sufficient rinsing performance by performing only a single dehydration rinsing in steps S1 to S11, the dehydration rinsing is repeated a plurality of times. For example, until the dehydration rinsing is performed three times (step S12), the operations of steps S1 to S11 are repeated, and the dehydration rinsing process is completed. If necessary, the pool rinse may be performed once after the completion of the dehydration rinsing step, but usually sufficient rinsing performance can be obtained only by the dehydrating rinsing step as described above.

Even if the position of the water supplied via the water falls within a specific range in the washing and dewatering tub 3, the water can be poured almost evenly over the entire laundry. In contrast, for example, in a washing machine configured so that the opening / closing operation of the drain valve 16 and the switching operation of the power switching mechanism 11 are performed in conjunction with each other,
The washing and dewatering tub 3 cannot be rotated with the drain valve 16 closed. That is, in such a configuration,
For example, when the switching operation of the power switching mechanism 11 is performed to rotate only the rotor 6 for washing or the like, the drain valve 16 is closed, and the power switching mechanism is configured to rotate the rotor 6 and the washing and dewatering tub 3 integrally. When the switching operation 11 is performed, the drain valve 16 is opened.

内へと落下する。FIGS. 5A and 5B are diagrams showing the structure of the water channel 40 in detail, wherein FIG. 5A is a top view of the outer tank cover 2a, and FIGS. 5B and 5C are lines A1-A2 and B1-B2, respectively. FIG. An inner rib 41 and an outer rib 42 extending upward are formed on the innermost periphery and the outer periphery of the outer tub cover 2a,
The portion sandwiched between the ribs 41 and 42 serves as a headrace 40. In addition, the outer circumferential rib 42 greatly spreads to the outer circumferential side at a portion connected to the water outlet 43 on the upper part of the circulation water supply channel 20,
A water receiving portion 44 is formed. Since the water receiving portion 44 has an appropriate downward inclination from the outer peripheral side toward the inner peripheral side, the water poured from the water discharge port 43 goes down the slope of the water receiving portion 44 to the headrace 40. Flow in. The outer rib 42 at a position other than the water receiving portion 44 is higher than the inner rib 41. For this reason, the water that flows into the headrace 40 and fills the entire circumference overflows the inner peripheral rib 41 and overflows into the lower washing and dewatering tub 3.
Fall into the inside.

落下させることができる。At the place where the water flows down the water receiving portion 44 and flows into the headrace 40, the flow of the water is strong, so that the inner circumferential rib 4 can be easily formed.
Although the water overflows beyond 1, the water force is weak in the headrace 40 away from the water receiver 44. Therefore, the height of the inner peripheral rib 41 is set to be highest at the water receiving portion 44, and to be lower as the distance from the water receiving portion 44 increases. Thereby, water can be dropped from the entire circumference of the water conduit 40 on average without being affected by the water force.
