  A washing machine according to a first aspect of the present invention is provided in a water receiving tub disposed in a main body, a washing / dehydrating tub enclosed in the water receiving tub and capable of dewatering rotation, and an upper end portion of the washing / dehydrating tub. A fluid balancer, a softener outflow device that is disposed in the fluid balancer and causes the softener to flow into the water receiving tank, a softener input port that is provided in the fluid balancer and communicates with the softener outflow device, and the softener The fluid balancer is provided with an annular rib on the inner peripheral side of the top surface, and the softener charging port lid is rotated in the vicinity of the opening of the softening agent charging port. In addition, a rib is provided on the inner peripheral side of the top surface so that the softener charging port lid is continuously provided at the same height as the annular rib in the closed state. It is.

  As a result, in the water supply and washing process after the start of operation, the softener charging port is stopped near the water supply port, and the water to be washed is put in the washing / dehydration tank. Even if the part scatters to the softener inlet by the object to be cleaned, it can be prevented from entering the softener inlet by the softener inlet lid. For this reason, it can reduce that the softening agent and water in a softening agent automatic outflow apparatus mix and water and the density | concentration of a softening agent falls. Therefore, it is possible to prevent the predetermined performance due to the softening agent from being lowered.

  In addition, when the softener charging port lid is closed, the top rib of the softener charging port lid is provided so as to be connected at substantially the same height as the substantially annular rib. When clothing is added to the balancer, it is possible to prevent the clothing from jumping out from the top of the balancer and entering the gap between the balancer and the upper cover. Thereby, damage to clothing can be prevented, a decrease in dewatering rotation can be prevented, and stable dewatering performance can be ensured.

  In addition, since the rib for the softener slot is provided so as to form part of the annular rib provided to prevent the entry of clothes, the softener slot can be easily opened and closed by handling the rib. Can be improved.

  Further, since the rotation angle of the softener charging port lid is regulated by the rib, the softener charging port lid 26 is inclined toward the softener charging port 23 even when the softening agent charging port lid is opened. Since the area to which the softening agent is charged becomes wide, the softening agent can be easily charged and the usability is improved. In addition, when the user closes the softening agent cover 26, the softening agent cover 26 can be easily closed as compared with the case where the user rotates 180 degrees, and the usability can be further improved. Further, even if the user forgets to close the softener charging cap after charging the softener, centrifugal force is applied in the first dehydration process after the washing process, and the softener charging cap closes the upper surface of the softener charging port. It will move, and the probability that a softening agent will become thin can be made low.

In the above, the rib of the softener slot cap is configured not to contact the upper end of the softener case.

  Since the rib of the softener inlet does not come into contact with the upper end of the softener case when the softener inlet lid is open, the softener inlet lid is provided and the softener inlet is arranged above the washing and dewatering tub. In this case, the softener case for storing the softener of the softener automatic spill device can be configured to be detachable.

  Therefore, the softener automatic spill device is located at the rear side of the washing machine, that is, below the rear surface of the opening of the upper frame, and stops at a position where it is difficult to put the softener from above the softener inlet. However, the user can put in and remove the softener case and put in the softener so that water can enter from the upper surface of the softener inlet during the washing process while maintaining the same usability as before. It can reduce, and it can prevent that the predetermined performance by a softening agent falls.

  Furthermore, since the rib is configured not to contact the upper end of the softener case and the rotation of the softener charging port lid is restricted by the rib from opening more than 180 degrees, the softener charging port lid is in the open state. In this case, the softener case can be attached and detached.

  The third invention further includes an upper cover that covers the balancer and is fixed to an upper portion of the water receiving tank, and the height of the annular rib is provided to be higher than the height of the upper cover. It is.

  As a result, the annular rib provided on the top surface of the fluid balancer is provided at a height higher than that of the upper cover, and the top surface rib of the softener charging port lid is connected at substantially the same height as the annular rib when the softener charging port lid is closed. By providing for installation, when clothes are added during dehydration, it is possible to more reliably prevent the clothes from jumping out from the upper part of the balancer and entering the gap between the balancer and the upper cover. Therefore, it is possible to prevent clothing from being damaged, and in addition, it is possible to prevent a decrease in dewatering rotation and to ensure stable dewatering performance.

It is principal part sectional drawing in the state where the clothing rose on the balancer upper part of a washing machine. More specifically, FIG. 6A is a cross-sectional view of the softener softener automatic outflow device 21 when it is moved to the second chamber 48, and FIG. FIG. 6C is a cross-sectional view when the softening agent flows out from the softening agent automatic outflow device 21 to the water receiving tank 3.

  As shown in FIGS. 5 and 6, the softener case 22 is detachably provided between the outer wall 44 and the inner wall 45 of the softener automatic spill device 21 provided in the fluid balancer 20. The first chamber 48 is provided via the first movement passage 47, the second chamber 50 is provided via the second movement passage 49, the third chamber 52 is provided via the third movement passage 51, and The softener outlet 55 is provided through the fourth moving passage 53 and the outflow passage 54.

  The movement of the softening agent in the above configuration will be described. First, the softening agent introduced into the softening agent case 22 at the start of the washing is subjected to the first force as indicated by an arrow a by the centrifugal force at the first dehydration step after the washing is finished. It moves to the first chamber 48 through the moving passage 47. The softening agent that has moved to the first chamber 48 is stuck to the outer wall 56 of the first chamber 48 by centrifugal force as indicated by b until the end of the first dehydration step. After the first dehydration step is completed, that is, during the first rinsing step, the softening agent moves to the second chamber 50 through the second movement passage 49 as indicated by an arrow c.

  Next, the softening agent moves to the third chamber 52 through the third movement passage 51 as indicated by an arrow d by the centrifugal force during the second dehydration step after the end of the first rinsing step. The softening agent that has moved to the third chamber 52 is stuck to the outer wall 57 of the third chamber 52 by centrifugal force as shown by e until the end of the second dehydration step. After the end of the second dehydration step, that is, at the final rinsing step, the softening agent passes through the fourth movement passage 53 as indicated by arrow f, and further passes through the outflow passage 54 as indicated by arrow g, and then, as indicated by arrow h. It exits from the outlet 55 and falls between the water receiving tub 3 and the washing and dehydrating tub 4.

  According to this embodiment configured as described above, as shown in FIGS. 1 to 4, the softener inlet 23 is covered on the upper part of the softener inlet 23 communicating with the softener case 22 for storing the softener. Since the softener charging port lid 26 is provided, water or the like scatters from above the softening agent charging port 23 in a state where the softening agent charging port lid 26 covers the softener charging port 23 before starting operation and during the washing process. Even so, it is possible to prevent water or the like scattered by the softener charging port lid 26 from entering the softener charging port 23 and the softener case 22.

  Therefore, as shown in FIG. 7, the softener case 22 is stopped in the vicinity of the water supply port 16 a, and the object to be cleaned 24 which has been dried to the vicinity of the opening 20 a of the fluid balancer 20 is put into the washing and dewatering tub 4. Even if the operation is started and tap water is supplied from the water supply port 16a and a part of the tap water is scattered by the article to be cleaned 24 to the softener input port 23, the softener input port 23 and the softener Intrusion into the case 22 can be prevented, and the softening agent in the softening agent case 22 and water can be mixed with each other to reduce the concentration of the softening agent. Therefore, it is possible to prevent the predetermined performance due to the softening agent from being lowered.

  As shown in FIG. 3 and FIG. 4, by providing the outer peripheral rib 25 a of the inlet inclined portion 25 around the softener inlet 23, water flows from the periphery of the softener inlet 23 toward the softener inlet 23. Even if it flows, the outer peripheral rib 25a blocks the water flowing toward the softener inlet 23, so that it is prevented that water tries to enter the softener inlet 23 from the horizontal direction of the softener inlet 23. be able to. Therefore, when tap water is supplied from the water supply port 16a, the water scattered around the softener input port 23 enters the softener input port 23 not only from above the softener input port 23 but also from the horizontal direction. Since it can prevent that it tries, it can further reduce that the softening agent in the softening agent case 22 mixes with the water and the concentration of the softening agent is lowered, and the predetermined amount by the softening agent is reduced. It is possible to further prevent the performance from deteriorating.

  Further, as shown in FIG. 3 and FIG. 4, by providing a lid rib 29 on the softener charging port lid 26 so as to be arranged outside the outer peripheral rib 25 a of the charging port inclined portion 25, the lid rib 29 and the charging port are provided. Since the water flowing from the horizontal direction can be blocked by the two ribs of the outer peripheral rib 25a of the inclined portion 25, it is possible to further prevent water from entering the softener inlet 23 from the horizontal direction. .

  Further, when the softener charging port lid 26 is made of a resin such as polypropylene, ABS, polyethylene, or polycarbonate, the outer peripheral rib 25a and the softener charging port lid 26 may be deformed due to thermal deformation during molding or deformation during actual use. The gap is formed by providing the lid rib 29, so that the deformation strength of the softener charging port lid 26 can be improved and the deformation of the softening agent charging port lid 26 can be reduced. The adhesion between the upper end surface 25b and the softener charging port lid 26 can be improved, and water can be further prevented from entering the softening agent charging port 23 from the horizontal direction. Therefore, it is possible to further reduce the decrease in the concentration of the softening agent due to the mixing of the softening agent and the water in the softening agent case 22 and further decrease the predetermined performance by the softening agent. Can be prevented.

  Further, since the water dropped on the upper surface of the softener charging port lid 26 flows down from the softener charging port lid 26, the water dropped on the upper surface of the softener charging port lid 26 is less likely to accumulate, and is near the softener charging port 23. The presence of water can be reduced, and the possibility of water entering the softener inlet 23 can be reduced.

  As shown in FIG. 2 and FIG. 3, by providing a bearing portion 27 for rotating the softener charging port lid 26 in the vicinity of the upper end surface 25 b of the outer peripheral rib 25 a of the charging port inclined portion 25, the softener charging port lid 26 and the softening agent are provided. Since the shaft portion 26b of the charging port lid 26 can be disposed on the upper part of the softening agent charging port 23, the softening agent case 22 of the softening agent automatic outlet 21 can be configured to be detachable.

  Therefore, as shown in FIG. 8, the softener automatic spill device 21 is positioned on the rear side of the washing machine 1, that is, below the rear surface 17 b of the opening 17 a of the upper frame 17, and above the softener inlet 23. Even if the softener is stopped at a position where it is difficult to put the softener, the user can attach and remove the softener case 22 and put in the softener. Sometimes, it is possible to reduce the intrusion of water from the upper surface of the softening agent inlet 23.

  Further, as shown in FIGS. 2 and 3, the shaft portion 26 b of the softener charging port lid 26 is disposed on the center side of the fluid balancer 20 in the softener charging port lid 26 in the circumferential direction. By providing the rotation restricting means 28 that restricts the rotation so as not to turn 180 degrees or more, even if the softener charging port lid 26 is opened, the softener charging port lid 26 faces the softener charging port 23 as shown in FIG. Therefore, even when the user puts the softener into the softener inlet 23, even if the softener flows through the softener inlet lid 26, the softener goes toward the softener inlet 23. Will flow. Therefore, even if the user causes the softener to flow not only to the softener charging port 23 but also to the softener charging port lid 26, the softening agent will flow into the softener charging port 23, and the softener is loaded. Since the area is increased, the softener can be easily introduced and the usability is improved.

  In addition, even if the user forgets to close the softener charging port lid 26 after the softener is loaded from the softener loading port 23, the softener loading port lid 26 does not open more than 180 degrees. Since the portion 26b is arranged in the center side of the fluid balancer 20 and in the circumferential direction in the softener charging port lid 26, a centrifugal force is applied to the softener charging port lid 26 in the first dehydration process after the washing process. Sometimes, the softener charging port lid 26 moves so as to close the upper surface of the softener charging port 23, and the probability that the softening agent is thinned can be reduced.

  Furthermore, even if the softener charging port lid 26 is rotated to the center side of the washing and dewatering tub 4, the softening agent charging port lid 26 stops in a state of being inclined toward the softening agent charging port 23. For this reason, when the user closes the softener charging port lid 26, the softener charging port lid 26 can be easily closed as compared with the case where the softener charging port lid 26 is rotated by 180 degrees.

  As shown in FIG. 4, the softener automatic spill device 21 has a detachable softener case provided below the softener charging port lid 26. When the softener charging port lid 26 is open, the softener Since the rib 26 a of the charging port lid 26 is configured not to contact the upper end of the softener case 22, the softening agent charging port lid 26 is provided and the softening agent charging port 23 is arranged above the washing and dewatering tub 4. In this case, the softener case 22 that stores the softener of the softener automatic drain device 21 can be configured to be detachable.

  Therefore, the position where the softener automatic spill device 21 is located behind the washing machine, that is, below the rear surface of the opening of the upper frame 17, and it is difficult to put the softener from above the softener charging port 23. Even if the user stops, the user can put in and remove the softener case 22 and put in the softener. Therefore, while maintaining the same usability as in the past, it is possible to reduce the ingress of water from the upper surface of the softener inlet 23 during the washing process, and to prevent the predetermined performance from being lowered by the softener. it can.

  As shown in FIGS. 3 and 4, the softener is allowed to flow through the softener charging port lid 26 by providing a lid rib 29 on the outer side of the surface of the softener charging port lid 26 that contacts the softener loading port 23. Since the lid rib 29 sometimes becomes a wall, it is better because the softening agent can be prevented from leaking from the softening agent inlet lid 26.

  Further, as shown in FIG. 8, even if clothes are added during the dehydration operation, even if the added clothes rise above the balancer 20 above the washing / dehydrating tank 4, the clothes are placed outside the washing / dehydrating tank 4. Can be prevented from entering the gap between the upper cover 3a and the balancer 20, and clothing damage can be prevented, and smooth dehydration rotation can be maintained and stable dehydration performance can be ensured.

  As described above, since the washing machine according to the present invention can obtain a predetermined performance by the softener, it can be applied not only to a domestic washing machine but also to an industrial washing machine.
