Description

  The present invention relates to a washing machine.

  2. Description of the Related Art Conventionally, a washing machine that performs a rinsing process called a so-called dehydration rinsing process is known. In the dewatering and rinsing step, first, water is supplied from above the laundry dewatering tank while rotating the laundry dewatering tank at a low speed, and water is soaked into the laundry in the laundry dewatering tank. Subsequently, the laundry dewatering tank is rotated at a high speed to dehydrate the laundry, and the detergent contained in the laundry is discharged together with the water soaked in the laundry. The dehydration rinsing process is also referred to as a shower rinsing process.

  When the dehydration rinsing process is started, the laundry is in a state of sticking to the inner peripheral wall of the laundry dewatering tub by the dehydration process performed before that. Therefore, in the washing machine described in Patent Document 1, the water discharged from the water outlet of the water supply pipe is directed to the inner peripheral wall of the laundry dewatering tub so that water can be easily applied to the laundry stuck to the inner peripheral wall. The structure which provides a direction change body is taken.

  Since the water discharge direction changing body has an inclined shape that approaches the inner peripheral wall of the laundry dewatering tank as it descends and has an arc shape that is substantially concentric with the inner peripheral wall of the laundry dewatering tank, the water supplied into the laundry dewatering tank is It falls to the inner peripheral wall of the washing and dewatering tank while spreading slightly in an arc shape.

Japanese Patent Application Laid-Open No. 07-222893

  In the structure of the washing machine disclosed in Patent Document 1, the water supplied into the washing and dewatering tub is slightly expanded in an arc shape in the water discharge direction changing body, but then gradually decreases due to the action of surface tension while falling. To go. For this reason, it is difficult for water to reach a wide range in the laundry, and it is difficult for water to sufficiently penetrate into the laundry.

  Therefore, a washing machine that can improve the rinsing performance of the shower rinsing process by sufficiently infiltrating the laundry with water is desired.

  A washing machine according to a main aspect of the present invention includes a laundry dewatering tub for storing laundry, and a water inlet provided above the laundry dewatering tub and connected to a water tap. Here, the water injection port portion is provided at the front end of the water flow channel through which water from the water tap flows, and a wall portion for blocking the flowing water, and the wall portion on the bottom surface of the water flow channel. A plurality of outflow holes arranged to flow out into the washing / dehydrating tub. The plurality of outflow holes allow water to flow out so that water from the outflow holes does not contact each other.

  According to the above configuration, the water flowing out from the water injection port does not squeeze as it descends, and the bottom of the laundry dewatering tub remains widely dispersed in a direction perpendicular to the radial direction of the laundry dewatering tub. To reach. Therefore, since the water supply operation in the shower rinsing process can sufficiently saturate the laundry, the detergent can be sufficiently discharged together with the water sufficiently soaked in the subsequent dehydration operation. Performance can be improved.

  The washing machine which concerns on this aspect WHEREIN: The said outflow hole part may be set as the structure containing the outflow hole opened in the bottom face of the said water flow path, and the deflecting body which changes the direction of the water which came out of the said outflow hole.

  According to said structure, the direction of the water which flows out from each outflow hole part can be adjusted.

  In the case of the above configuration, the water injection port portion may be further arranged such that the inner peripheral wall of the washing / dehydrating tub is located behind the outflow hole portion. In this case, at least a part of the deflecting bodies directs the water exiting the outflow hole to the rear.

  With such a configuration, water can flow out from the water supply port so as to be closer to the inner peripheral wall side of the laundry dewatering tub, so that the dewatering step before the shower rinsing step moves to the inner peripheral wall of the laundry dewatering tub. Water can be effectively applied to the laundry that has been stuck.

  When it is set as said structure, the direction of each said deflecting body may be set so that the water which flowed out from the said several outflow hole part may form the circular arc along the inner peripheral wall of the said washing | cleaning dewatering tank.

  With such a configuration, it is possible to effectively pour water on the laundry stuck to the inner peripheral wall of the laundry dewatering tub.

  The washing machine which concerns on this aspect WHEREIN: The water which flowed out from the said several outflow hole part may be set as the structure which forms the circular arc which follows the inner peripheral wall of the said washing | cleaning dewatering tank.

  According to said structure, water can be effectively poured on the laundry stuck to the inner peripheral wall of the washing dewatering tank.

  In the washing machine according to this aspect, the flow channel may include a first flow channel provided with the outflow hole portion and a second flow channel provided separately from the first flow channel. In this case, in the water injection port portion, the water flowing through the second flow channel is lateral to the supply region to which the water from the outflow hole portion is supplied, and the washing dehydration tub is more than the supply region. A discharge port for discharging toward a position close to the inner peripheral wall is provided.

  According to the above configuration, water is supplied to the portion of the laundry that is closer to the inner peripheral wall of the laundry dewatering tub than the supply region by the outflow hole portion, and water can easily sufficiently soak into this portion, so the shower rinsing step The rinsing performance can be further improved.

  When it is set as said structure, the detergent container accommodated so that withdrawing / inserting in the said water injection port part can be further provided. In this case, the water injection port portion includes a first water passage that allows water from the water tap to flow out to the first flow channel through the detergent container, and water from the water tap without the detergent container. It is set as the structure further including the 2nd water flow path which flows out into a 2 flow water channel.

  If it is set as such a structure, since water will be directly supplied from a 2nd water channel to a 2nd water channel without going through a detergent container, water will flow in vigorously and will flow through a 2nd water channel. . Thereby, since water can be discharged | emitted vigorously from a discharge port, water can be thrown away and water can reach the target position near the inner peripheral wall of a washing dewatering tank.

  In the case of the above configuration, the bottom surface of the first flow channel includes a first inclined surface that goes down to the outflow hole portion side, and the bottom surface of the second flow channel includes a second inclined surface that goes down to the discharge port side. It can be configured. In this case, the gradient of the second inclined surface is made larger than the gradient of the first inclined surface.

  With such a configuration, since the second inclined surface having a larger gradient than the first inclined surface of the first flowing water channel is formed on the bottom surface of the second flowing water channel, the second flowing water channel is more vigorously driven. Water can flow and water can be discharged more vigorously from the discharge port.

  ADVANTAGE OF THE INVENTION According to this invention, the washing machine which can improve the rinse performance by a shower rinse process can be provided.

The outflow hole 222 includes a circular outflow hole 223 formed on the bottom surface of the central flow channel 217 and a deflector 224 provided at the outlet of the outflow hole 223. The deflecting body 224 changes the flow of water exiting from the outflow hole 223.

  The deflecting body 224 includes an arc-shaped side wall portion 224a and a bottom wall portion 224b having a shape slightly less than a semi-disc. The deflecting body 224 of the central outflow hole 222 is provided so as to face directly behind. Further, the deflecting body 224 of the right end outflow hole 222 is provided so as to face the right side, and the deflecting body 224 of the left end outflow hole 222 is provided so as to face the left side. Further, the deflecting body 224 of the outflow hole portion 222 located right next to the central outflow hole portion 222 is provided so as to face a little right from the rear, and the deflecting body 224 of the outflow hole portion 222 located right next to the center is , Provided to face slightly behind the right side.

  As shown in FIG. 6A, in the state where the water supply unit 50, that is, the water injection port portion 200 is disposed at the rear portion of the upper surface plate 12, the laundry is removed behind the plurality of outflow hole portions 222 arranged. The inner peripheral wall of the water tank 21 is located. Further, the central outflow hole 222 is located at the center P in the left-right direction of the washing / dehydrating tub 21.

  Next, the water supply operation by the water supply unit 50 will be described.

  When the water supply valve 51 is opened, water is introduced from the water tap into the water supply unit 50. Water from the water tap flows from the intake port 204 to the central water passage 205, the right water passage 206, and the left water passage 207, and reaches the central water passage 208, the right water passage 209, and the left water passage 210.

  As shown by the arrows in FIG. 4A, the water that has reached the central water inlet 208 flows into the detergent container 100 from the central water outlet 208, flows backward through the bottom surface of the inclined detergent container 100, and opens. It flows out from the rear surface of 100 to the rear of the central flow channel 217. The water flowing out to the central flow channel 217 is guided forward by the inclined surface 217 a of the central flow channel 217 and is blocked by the wall 214, and flows out from a plurality of outflow holes 222 provided in front of the wall 214. . At this time, in the outflow hole portion 222, the direction is changed by the deflecting body 224 after exiting the outflow hole 223 as indicated by the arrow S2 and the water that is output from the outflow hole 223 as indicated by the arrow S1 and slightly forward. Mix with water. The water that finally flows out from the outflow hole 222 is directed to the direction in which the two directions are combined as indicated by an arrow S3. The direction of the water finally flowing out from each outflow hole 222 (arrow S3) is determined by the direction of the deflecting body 224. Here, the “direction of the deflecting body 224” means a direction perpendicular to the end face of the bottom wall portion 224b and going out of the deflecting body 224 from the end face.

  Further, the direction of the water flowing out from each outflow hole 222 (arrow S3) is also determined by the amount of blocking of the outflow hole 223 by the deflecting body 224, in other words, by the opening amount of the outflow hole 223. That is, when the amount of blockage is large, the amount of water passing through the deflecting body 224 increases, so that the vector component of the arrow S2 becomes large, and the outflowing water becomes easier to move in the horizontal direction. When the amount of water is small, the amount of water directly flowing out from the outflow hole 223 increases, so that the vector component of the arrow S1 becomes large, and the outflowing water is more easily directed in the vertical direction.

  On the other hand, as shown by the arrows in FIG. 4B, the water that has reached the right water passage hole 209 flows from the right water passage hole 209 to the rear portion of the right water passage 218, and the aspect of the corner portion of the right water passage 218. It flows forward while being energized by the shape and the inclined surface 218 a and is discharged from the right discharge port 220. Similarly, water that has flowed into the left flow channel 219 from the left water passage hole 210 is discharged from the left discharge port 221.

  FIG. 7 is a diagram for explaining how water flows from the water injection port 200 of the water supply unit 50. In addition, in FIG.7 (b), the external shape of the water inlet part 200 and the external shape of the outflow hole part 222 are shown with a dashed-dotted line.

  In each outflow hole 222, the direction of the deflecting body 224 is set as described above. Thereby, the water flowing through the central flow channel 217 flows out from each outflow hole 222 in the direction indicated by the arrow in FIG. That is, water flows out from the central outflow hole portion 222 slightly rearward from just below. In addition, water flows out from the first outflow hole 222 from the center to the right and slightly diagonally rearward from right below, and from the second outflow hole 222 from the center to the right from below. The water flows out slightly to the right, and the water flows out from the right end outflow hole portion 222 slightly diagonally to the front right below. Further, water flows out from the first outflow hole 222 from the center to the left and slightly diagonally left behind from below, and from the second outflow hole 222 from the center to the left from below. The water flows out slightly to the left side, and the water flows out from the left end outflow hole portion 222 slightly diagonally to the left from directly below. Since the water flowing out from each outflow hole portion 222 does not cross each other, it does not squeeze downward as shown in FIG. 7 (b), and as shown in FIG. Reaches the bottom of the washing and dewatering tub 21 while being widely dispersed in the direction perpendicular to the horizontal direction, that is, in the left-right direction. Further, as shown in FIG. 7B, the water that flows out from each outflow hole 222 forms an arcuate supply region D that follows the inner peripheral wall of the laundry dewatering tub 21. In the central outflow hole 222 and the outflow holes 222 on both sides thereof, water flows out backward, so that the supply region D is behind the arrangement position of the plurality of outflow holes 222, that is, inside the washing and dewatering tank 21. It is formed near the peripheral wall.

  As shown in FIG. 7A, the water flowing through the right flow channel 218 and the left flow channel 219 is discharged from the right discharge port 220 and the left discharge port 221 obliquely forward. As shown in FIG. 7B, the discharged water is located on the side of the water supply region D by the outflow hole 222 and closer to the inner peripheral wall of the washing and dewatering tub 21 than the supply region D. To reach.

  In the present embodiment, the first rinsing process among the rinsing processes performed twice according to the driving course is the shower rinsing process. Alternatively, both of the two rinsing steps are the shower rinsing step.

  In the shower rinsing process, in the first water supply operation, water is supplied from the water supply unit 50 and the washing / dehydrating tub 21 rotates at a low speed. As the laundry dewatering tank 21 rotates, the laundry sequentially passes below the water supply unit 50. As described above, since water is supplied from the outflow hole portion 222 of the water supply unit 50 over a wide area along the inner peripheral wall of the laundry dewatering tub 21, when the laundry passes below the water supply unit 50, Regardless of the position in the water tank 21, water can be uniformly applied to the laundry. Furthermore, since water is supplied from the right discharge port 220 and the left discharge port 221 to the portion of the laundry that is closer to the inner peripheral wall of the laundry dewatering tub 21 than to the supply region D, this portion may be sufficiently filled with water. it can.

  Thereafter, when a dehydrating operation for rotating the laundry dewatering tank 21 at a high speed is performed, the detergent is sufficiently discharged together with water sufficiently soaked in the laundry.

<Effect of Embodiment>
As described above, according to the present embodiment, the water injection port portion 200 of the water supply unit 50 is provided with the plurality of outflow hole portions 222 arranged along the wall portion 214 of the front end portion, and these outflow hole portions 222. However, it is set as the structure which flows out water so that the water from each outflow hole part 222 may not contact. As a result, the water flowing out from the water injection port 200 does not squeeze as it descends, and reaches the bottom of the laundry dewatering tub 21 while being widely dispersed in the direction perpendicular to the radial direction of the laundry dewatering tub 21. reach. Therefore, since the water supply operation in the shower rinsing process can sufficiently saturate the laundry, the detergent can be sufficiently discharged together with the water sufficiently soaked in the subsequent dehydration operation. Performance can be improved.

  In addition, since the water from the water supply unit 50 spreads over the laundry widely, when the softener is added together with the water from the water supply unit 50 during the shower rinsing process, the softener can be spread over the laundry evenly. it can. Thereby, the rinsing process in which the softener is added can be a shower rinsing process, and the water-saving effect of the fully automatic washing machine 1 can be enhanced.

  Furthermore, according to the present embodiment, since the deflecting body 224 is provided in each outflow hole 222, the direction of water flowing out from each outflow hole 222 can be adjusted. In particular, by adjusting the direction of each deflecting body 224 and the amount of closing of each outflow hole 223 by each deflecting body 224, the water flowing out from each outflow hole 222 is circular so that it follows the inner peripheral wall of the laundry dewatering tub 21. Since the arc-shaped supply region D is formed, water can be effectively applied to the laundry stuck to the inner peripheral wall of the laundry dewatering tub 21 in the dewatering step before the shower rinsing step. Further, the center and the deflecting bodies 224 on both sides thereof are set in a direction in which water is directed rearward, and the supply region D is formed closer to the inner peripheral wall of the washing / dehydrating tub 21 than the arrangement position of the plurality of outflow hole portions 222. Since it was made to do, water can be more effectively poured on the laundry stuck to the inner peripheral wall of the washing and dewatering tank 21. In the present embodiment, the laundry dewatering tub 21 is tilted forward, and as shown in FIG. 1, the lower part of the inner peripheral wall of the laundry dewatering tub 21 is positioned more rearward in the rear part of the fully automatic washing machine 1. Become. Therefore, in the fully automatic washing machine 1 in which the laundry dewatering tub 21 is tilted forward, the configuration in which the supply region D is formed rearward is more important for bringing the supply region D closer to the inner peripheral wall of the laundry dewatering tub 21. This is more useful for improving the rinsing performance by shower rinsing.

  Furthermore, according to the present embodiment, the right flow channel 218 and the left flow channel 219 are provided on the left and right sides of the water injection port 200, and water flowing through these flow channels 218, 219 is supplied from the right discharge port 220 and the left discharge port 221. It was made to discharge | release, and it was made to hang | release the discharged | emitted water to the position which was side of the water supply area | region D by the outflow hole part 222, and was closer to the inner peripheral wall of the washing | cleaning dewatering tank 21 rather than the said supply area | region D. As a result, water is supplied to the portion of the laundry closer to the inner peripheral wall of the washing and dewatering tub 21 than the supply region D, and water can easily penetrate into this portion, so that the rinsing performance by the shower rinsing process is further improved. Can be made.

  Furthermore, according to the present embodiment, water is directly supplied to the right flow channel 218 and the left flow channel 219 from the right flow channel 206 and the left flow channel 207 without the detergent container 100. The water flows in vigorously and flows through the right flow channel 218 and the left flow channel 219. As a result, water can be discharged from the right discharge port 220 and the left discharge port 221 vigorously, so that it is possible to make the water reach a target position close to the inner peripheral wall of the washing and dewatering tub 21 by flying the water far away.

  Furthermore, according to the present embodiment, inclined surfaces 218a and 219a having a larger gradient than the inclined surface 217a formed on the bottom surface of the central flow channel 217 are formed on the bottom surfaces of the right flow channel 218 and the left flow channel 219. . Thereby, since water flows more vigorously through the right flow channel 218 and the left flow channel 219, water can be discharged more vigorously from the right discharge port 220 and the left discharge port 221.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications other than those described above can be made to the embodiments of the present invention. .

  For example, in the above embodiment, the wall 214 extending straight in the left-right direction is formed at the front end of the water injection port 200, and the plurality of outflow holes 222 are arranged straight along the wall 214. However, as shown in FIG. 8A, an arcuate wall 214A is formed at the front end of the water injection port 200A along the inner peripheral wall of the washing and dewatering tank 21, and a circle is formed along the wall 214A. A plurality of outflow holes 222A may be arranged in an arc. In this case, the direction of the deflecting body 224A of each outflow hole portion 222A can be the same, for example, all can be set to be directly rearward. In FIG. 8A, a water inlet 200A from which the cover 203 and the upper case 202 are omitted is illustrated.

  Even in such a configuration, the water flowing out from the respective outflow hole portions 222A does not cross each other, so that it does not squeeze as it descends, and the laundry is removed while being widely dispersed in the left-right direction. It reaches the bottom of the aquarium 21. Further, since each outflow hole 222 is arranged in an arc shape so as to follow the wall portion 214 </ b> A, the water flowing out from each outflow hole portion 222 is supplied in an arc shape along the inner peripheral wall of the laundry dewatering tub 21. Form a region. Further, since water from all the outflow holes 222 flows backward, the supply region is formed behind the arrangement position of the plurality of outflow holes 222A, that is, closer to the inner peripheral wall of the laundry dewatering tub 21. . Therefore, the same effect as the above embodiment can be obtained.

  Furthermore, in the said embodiment, the water supply unit 50 is comprised by the detergent container 100 and the water inlet part 200. FIG.

Further, the central water inlet 208 </ b> B formed in the central water passage 205 </ b> B is provided behind the central water outlet 208 formed in the central water passage 205 of the water injection port 200.

  Furthermore, in the above embodiment, if the supply region D is located too far, the water that has flowed out may come into contact with the balance ring 22, so that only the center and the outflow hole portions 222 on both sides of the water flow toward the rear. The direction of the deflecting body 224 is set. However, when there is no possibility that the water that has flowed out contacts the balance ring 22 and the supply region D can be positioned more rearward, the deflecting body so that the water is directed rearward in all the outflow holes 222. The orientation of 224 may be set.

  Furthermore, in the above embodiment, the outflow hole 223 of the outflow hole 222 is formed in a circular shape. However, the outflow hole 223 may have another shape, for example, a quadrangle, a triangle, or an ellipse. The shape of the deflecting body 224 can be changed according to the shape of the outflow hole 223.

  Furthermore, in the above-described embodiment, both the right flow water channel 218 and the left flow water channel 219 are provided in the water injection port 200. However, the water inlet 200 may be provided with either the right-hand water channel 218 or the left-hand water channel 219. Furthermore, the water inlet 200 may not be provided with either the right flow water channel 218 or the left flow water channel 219.

  Furthermore, in the said embodiment, the detergent container 100 may be divided into the 1st accommodating part which accommodates a powder detergent, and the 2nd accommodating part which accommodates a softening agent. Furthermore, the detergent container 100 may be partitioned into a first housing portion, a second housing portion, and a third housing portion that houses the liquid detergent.

  Furthermore, in the said embodiment, although the outer tank 20 and the washing | cleaning dehydration tank 21 incline ahead, these do not need to incline.
