  However, the configuration of the conventional washing machine as shown in FIGS. 6 to 10 has the following problems.

  A customer's need for a washing machine in recent years is that the outside dimensions (including the height direction) of the washing machine 1 are small and that the capacity for storing the object to be cleaned 23 is increased.

  Therefore, as shown in FIG. 6, the conventional washing machine 1 when the outside diameter of the washing machine 1 has a margin has a larger capacity of the washing and dewatering tub 4 than the amount of the object to be cleaned 23. Therefore, even if a predetermined amount of the object to be cleaned 23 is put into the washing and dewatering tub 4, it is possible to prevent the object to be cleaned 23 from protruding from the washing and dewatering tub 4. In recent washing machines 1, as shown in FIG. 8, the capacity of the washing and dewatering tub 4 is made substantially equal to the amount of the object to be cleaned 23, and the outside dimensions of the washing machine 1 are reduced as much as possible. I am doing so.

  When the capacity of the washing and dewatering tub 4 is made substantially equal to the amount of the object to be cleaned 23, when the object to be cleaned 23 is put in, the object to be cleaned 23 contains moisture by the washing water, Since the object to be cleaned 23 is swelled, as shown in FIG.

  In order to prevent the object to be cleaned 23 from jumping out of the washing / dehydrating tub 4, a balancer rib 24 is provided on the upper part of the fluid balancer 20, as shown in FIG. As shown in FIG. 9, the balancer rib 24 is also provided at the softener charging port 22 on the side opposite to the rotation center of the washing / dehydrating tub 4 so that the object to be cleaned 23 is washed and removed. Jumping out of the water tank 4 can be prevented.

  However, in the washing machine 1, when the previous series of operations is completed, the washing and dewatering tub 4 stops at an arbitrary position. Therefore, the automatic softener outlet 21 and the softener inlet 22 provided in the fluid balancer 20 are used. Cannot be determined at which position. Therefore, as shown in FIG. 10, the softener charging port 22 is stopped in the vicinity of the water supply port 16a of the water supply valve 16, and the object to be cleaned 23 which is dried to the vicinity of the opening 20a of the fluid balancer 20 is washed and dewatered. 4 is started and the washing water is supplied from the water supply port 16a. Depending on the state of the object to be cleaned 23, a part of the washing water may be automatically softened by the object 23 to be cleaned. It will scatter to the outflow device 21 side and may enter the softener automatic outflow device 21 through the softener inlet 22 of the fluid balancer 20. Therefore, the softener and the washing water in the softener automatic spill device 21 are mixed with each other during the washing water supply in the washing process, and the concentration of the softener is lowered. The softening agent overflows and the predetermined amount of softening agent is not stored in the automatic softener outflow device during the washing process. For this reason, the predetermined amount of softening agent is not put into the washing and dehydrating tank in the final rinsing process. In addition, there arises a problem that a predetermined performance by the softening agent cannot be obtained.

  The present invention solves the above-described conventional problems, and an object thereof is to obtain a predetermined performance by a softening agent in a rinsing process.

In order to solve the above-described conventional problems, a washing machine of the present invention includes a water tub provided in a main body and having a washing and dewatering tub that can be dewatered and rotated inside, and a bottom surface of the washing and dewatering tub. A pulsator provided, a fluid balancer provided at the upper end of the washing and dewatering tub, a softener automatic spill device arranged in the fluid balancer and allowing the softener to flow into the water tub before the final rinsing process, and washing, Control means for controlling a series of operations such as rinsing and dehydration, and a softener charging port provided in the fluid balancer and communicating with the softener automatic outflow device, and provided with a balancer rib substantially at the top of the fluid balancer , A balancer rib is provided around the softener charging port, and a notch is provided in a part of the balancer rib provided on the softener charging port on the opposite side of the rotation center of the washing / dehydrating tub.

  Thus, the washing object can be prevented from jumping out of the washing and dewatering tank, and when the washing water is supplied from the water supply port, a part of the washing water is automatically discharged by the washing object. It is possible to prevent splashing to the side and entering the softener automatic outlet device through the softener inlet of the fluid balancer.

  The washing machine of the present invention can prevent the object to be washed from jumping out of the washing and dewatering tank, and when washing water is supplied from the water supply port, a part of the washing water is softened by the object to be washed. It is possible to prevent splashing into the automatic agent outflow device side and entering the softener automatic outflow device via the softener inlet of the fluid balancer.

  Therefore, since the washing water does not enter the softener inlet when washing water is supplied during the washing process, the softener and washing water in the storage section of the softener automatic spill device mix and the softener concentration decreases. Never do. In addition, the softener overflows from the storage part of the softener automatic spill device, and a predetermined amount of softener is not stored in the storage part of the softener automatic spill device during the washing process. Will not be able to be put into the washing and dewatering tank. Thus, the predetermined performance by the softener can be stably obtained.

A first invention includes a water tank having a washing and dewatering tub disposed in a main body and capable of dewatering rotation therein, a pulsator rotatably disposed on a bottom surface of the washing and dewatering tank, and the washing and dewatering tank A fluid balancer provided at the upper end of the fluid, a softener automatic drain device arranged on the fluid balancer to allow the softener to flow into the water tank before the start of the final rinsing process, and a series of operations such as washing, rinsing and dewatering are controlled. A control means, and a softener inlet provided in the fluid balancer and communicating with the softener automatic outflow device. A balancer rib is provided at a substantially upper portion of the fluid balancer, and the balancer rib is disposed around the softener inlet. provided, wherein it is the center of rotation of the washing and dewatering tank softener inlet to that provided partially cutaway portion of the Baransaribu provided on the opposite side, the object to be cleaned is jumping out from the washing and dewatering tank When washing water is supplied from the water supply port, a part of the washing water scatters to the softener automatic spill device side by the object to be cleaned and passes through the softener inlet of the fluid balancer. It is possible to prevent entry into the softener automatic spill device.

  Therefore, since the washing water does not enter the softener inlet when washing water is supplied during the washing process, the softener and washing water in the storage section of the softener automatic spill device mix and the softener concentration decreases. Never do. In addition, the softener overflows from the storage part of the softener automatic spill device, and a predetermined amount of softener is not stored in the storage part of the softener automatic spill device during the washing process. Will not be able to be put into the washing and dewatering tank. Thus, the predetermined performance by the softener can be stably obtained.

In addition, by providing a balancer rib around the softener charging port, it is possible to clarify which range the softener can be fed into the automatic softener outflow device with the balancer rib. The person can easily put the softener into the softener inlet, and can supply a predetermined amount of the softener to the storage portion of the softener automatic spill device. A predetermined performance by the softening agent can be stably obtained by putting it in the dehydration tank.

Further, by providing a notch in a part of the balancer rib provided on the opposite side of the rotation center of the washing and dewatering tub of the softener charging port, the softener may overflow from the softener charging port. From the notch, it can flow into the gap between the fluid balancer and the water tank and can flow to the bottom of the water tank. Thereby, for example, even when the softener flows backward from the softener automatic outflow device 21 and overflows from the softener inlet 22 during the first dehydration process, due to the centrifugal force of the washing and dewatering tank 4, Since the softening agent that has flowed out in the reverse direction flows from the notch 24 a of the balancer rib 24 toward the water tank 3, the softening agent jumps out of the softener charging port 22 and the upper ends of the balancer ribs 24 and out of the water tank 3. The floor surface on which the washing machine 1 or the washing machine 1 is placed without splashing, adhering to the back surface of the lid 18 or the upper frame 17 or falling on the floor surface on which the washing machine 1 is placed. Can be prevented from getting dirty.

(Embodiment 1)
Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.

  In the washing machine 1 shown in FIG. 1, a water tub 3 is suspended by a suspension rod 2, and a washing and dewatering tub 4 is provided inside the water tub 3 so as to be able to spin and dehydrate. The washing and dewatering tub 4 has a pulsator 5 rotatably disposed at the bottom, and a lower blade 6 is provided integrally with the pulsator 5. The driving means 7 drives the pulsator 5 or the washing and dewatering tub 4 via the V belt 8 and the speed reduction mechanism 9.

  The lint circulation water channel 10 and the sprinkling nozzle circulation water channel 11 are provided so as to extend from the pump chamber 12 on the outer periphery of the lower blade 6 of the pulsator 5 to the upper part of the washing and dewatering tub 4, and a lint filter 13 detachably attached to the upper part. A watering nozzle 14 is provided. The drain valve 15 drains the washing water in the water tank 3, and the water supply valve 16 supplies water into the water tank 3. A lid 18 is provided on the upper frame 17 constituting the upper portion of the washing machine 1 so as to be freely opened and closed, and a control means 19 is provided in front of the lid 18. A fluid balancer 20 for reducing vibration during dehydration is provided at the top of the washing and dewatering tub 4, and a softener automatic outflow device 21 is provided at the center of the fluid balancer 20.

  The water supply port 16 a communicating with the water supply valve 16 is an opening of the fluid balancer 20 of the washing and dewatering tank 4 so that the tap water from the water supply valve 16 is reliably supplied into the washing and dewatering tank 4 in the water tank 3. It is arranged substantially above 20a.

  In addition, as shown in FIG. 2, since the softening agent inlet 22 which communicates with the softening agent automatic outflow apparatus 21 is provided in the part in which the softening agent automatic outflow apparatus 21 of the fluid balancer 20 is disposed, The softening agent can be put into the softening agent automatic outlet 21 through the softening agent inlet 22.

  In order to prevent the object to be cleaned 23 from jumping out of the washing and dewatering tub 4, as shown in FIG. 1, balancer ribs 24 are provided along the inner periphery of the fluid balancer 20 at substantially the upper part of the fluid balancer 20. A balancer rib 24 is also provided in the vicinity of the softener charging port 22 on the rotation center side of the washing and dewatering tub 4 of the softener charging port 22 as shown in FIG.

  Thereby, when the washing water is supplied from the water supply port 16 a, a part of the washing water is scattered to the softener automatic outflow device 21 side by the article to be cleaned 23 and passes through the softener inlet 22 of the fluid balancer 20. It is possible to prevent the softener automatic outflow device 21 from entering.

  Moreover, it can prevent that the to-be-cleaned object 23 mounts on the upper part of the softening agent inlet 22.

  To explain the operation in the above configuration, the user opens the lid 18, puts an object to be cleaned 23 such as clothes into the washing and dewatering tub 4, turns on the washing machine 1, and presses a start button (not shown). Then, the washing and dewatering tub 4 rotates forward and backward by the driving means 7 to detect the amount of the object 23 to be cleaned. Since the amount of detergent required is displayed on the operation unit (not shown), the user first puts the detergent into a predetermined position (may be in the washing and dehydrating tub 4), and then a predetermined amount of softening agent. Then, a predetermined amount of washing water is supplied from the water supply port 16a into the washing and dewatering tub 4 through the water supply valve 16.

  When a predetermined amount of washing water is supplied, the pulsator 5 rotates forward and backward to perform the washing process of washing the article 23 to be cleaned.

  When the washing process for a predetermined time is completed, the washing water in the water tub 3 is drained out of the washing machine 1 by the drain valve 15. When the washing water is drained, the washing and dewatering tank 4 rotates at a high speed (for example, 300 r / min), and the first dewatering process is performed.

  When the first dehydration process is completed, the rinsing water is supplied, the pulsator 5 rotates forward and backward, and the first rinsing process for rinsing the article 23 to be cleaned is performed. When the first rinsing process is completed, the washing water in the water tub 3 is drained out of the washing machine 1, and the second dehydration process (for example, the number of rotations of the washing and dehydrating tank 4 is 300 r / min) Rotate at high speed). Further, the rinsing water is supplied and the final rinsing process is performed, and then the washing water in the water tank 3 is drained, and the third dehydration process (for example, the number of rotations of the washing and dehydrating tank 4 is 800 r / min. The water tank 4 rotates at high speed).

  When the third dehydration process is performed, the operation ends.

  Next, the operation of the softening agent flowing in the softening agent automatic outflow device 21 according to this operation will be described.

  FIG. 3 is a cross-sectional view of the main part in the softener automatic efflux device 21 through which the softener flows, and FIG. 4A is a cross-sectional view of the softener softener automatic efflux device 21 when it moves to the second chamber 48. 4B is a cross-sectional view when the softening agent is moved to the fourth chamber 52, and FIG. 4C is a cross-sectional view when the softening agent is discharged from the softening agent automatic outflow device 21 to the water tank 3. .

  As shown in FIGS. 3 and 4, a softener reservoir 46 is provided between the outer wall 44 and the inner wall 45 of the softener automatic spill device 21 provided in the fluid balancer 20. A first chamber 48 is provided via the moving passage 47, a second chamber 50 is provided via the second moving passage 49, a third chamber 52 is provided via the third moving passage 51, and A softener outlet 55 is provided via the four moving passages 53 and the outflow passage 54.

  The movement of the softening agent in the above configuration will be described. First, at the start of washing, the softening agent introduced into the storage unit 46 from the softening agent inlet 22 is subjected to an arrow due to the centrifugal force during the first dehydration process after washing. It moves to the 1st chamber 48 through the 1st movement channel | path 47 like a. The softening agent that has moved to the first chamber 48 is stuck to the outer wall 56 of the first chamber 48 by the centrifugal force during the first dehydration stroke as shown in b until the end of the first dehydration stroke. Since the centrifugal force disappears after the first dehydration process, that is, during the first rinsing process, 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 path 51 as indicated by an arrow d by the centrifugal force during the second dehydration process after the end of the first rinsing process. 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 process. Since the centrifugal force disappears after the end of the second dehydration process, that is, in the final rinsing process, the softener passes through the fourth movement path 53 as indicated by the arrow f, and further passes through the outflow path 54 as indicated by the arrow g. It exits from the softener outlet 55 as shown in h and falls between the water tub 3 and the washing and dewatering tub 4.

  According to the present embodiment configured as described above, as shown in FIGS. 1 to 5, the balancer rib 24 is provided along the inner periphery of the fluid balancer 20 at substantially the upper portion of the fluid balancer 20, Further, by providing the balancer rib 24 on the rotation center side of the washing / dehydrating tub 4 as well, it is possible to prevent the article to be cleaned 23 from jumping out of the washing / dehydrating tub 4, and the wash water is supplied from the water supply port 16a. At that time, a part of the washing water is scattered by the article to be cleaned 23 toward the softener automatic spill device 21 and enters the softener automatic spill device 21 through the softener inlet 22 of the fluid balancer 20. Can be prevented.

  Therefore, since the washing water does not enter the softening agent inlet 22 during the washing water supply in the washing process, the softening agent and the washing water in the storage unit 46 of the softening agent automatic drain device 21 are mixed and the softening agent. The softener overflows from the reservoir 46 of the softener automatic spill device 21 and a predetermined amount of softener is stored in the reservoir 46 of the softener automatic spill device 21 during the washing process. In addition, since a predetermined amount of the softening agent cannot be put into the washing and dewatering tub 4 in the final rinsing process, a predetermined performance by the softening agent can be obtained.

  Further, as shown in FIG. 2, by providing a balancer rib 24 around the softener inlet 22, it is possible to reliably supply the softener into the softener automatic flow-out device 21 by which range the softener is charged by the balancer rib 24. Therefore, the user can easily put the softening agent into the softening agent inlet 22, and can supply a predetermined amount of the softening agent to the storage unit 46 of the softening agent automatic outflow device 21, In the final rinsing process, a predetermined amount of softening agent is put into the washing and dehydrating tub 4 so that it is possible to reliably obtain a predetermined performance by the softening agent.

  Further, since the softening agent is a highly viscous liquid, when the washing machine 1 is used for a long period of time, a part of the path through which the softening agent of the softening agent automatic outflow device 21 flows, for example, the first moving path 47 and the second moving path. 49, the softening agent adheres to the third moving passage 51 and the like, and a part of the path through which the softening agent flows is blocked by the softening agent, so that the softening agent does not flow in the softening agent automatic outflow device 21. there is a possibility. If the user inputs the softener from the softener inlet 22 in such a state, the softener overflows from the softener inlet 22, and if the first dehydration process is performed as it is, the softener inlet The softening agent overflowing from 22 jumps out from the upper ends of the softening agent inlet 22 and the balancer rib 24 and scatters out of the water tub 3, adheres to the back surface of the lid 18, the upper frame 17, or the washing machine 1. Or the floor surface on which the washing machine 1 is placed may be soiled.

  Therefore, in order to prevent such a situation from occurring, as shown in FIG. 2, a cutout portion is formed in a part of the balancer rib 24 on the side opposite to the rotation center of the washing / dehydrating tub 4 of the softener charging port 22. By providing 24 a, even if the softening agent overflows from the softening agent inlet 22, it flows from the notch 24 a to the gap between the fluid balancer 20 and the water tank 3 and flows to the bottom of the water tank 3. Can be. Thereby, for example, even when the softener flows backward from the softener automatic outflow device 21 and overflows from the softener inlet 22 during the first dehydration process, due to the centrifugal force of the washing and dewatering tank 4, Since the softening agent that has flowed out in the reverse direction flows from the notch 24 a of the balancer rib 24 toward the water tank 3, the softening agent jumps out of the softener charging port 22 and the upper ends of the balancer ribs 24 and out of the water tank 3. The floor surface on which the washing machine 1 or the washing machine 1 is placed without splashing, adhering to the back surface of the lid 18 or the upper frame 17 or falling on the floor surface on which the washing machine 1 is placed. Can be prevented from getting dirty.

  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.
