As shown in FIG. 12, the softener cartridge 122 can be attached to and detached from the fluid balancer 120. The user can remove the softener case 122 from the fluid balancer 120 and put the softener into the softener case 122. Further, a portion of the fluid balancer 120 in which the softener case 122 is disposed is provided with a softener input port 123. Therefore, the user can also put the softener into the softener case 122 from the softener inlet 123 without removing the softener case 122.

The basic operation stroke of the washing machine 100 includes water supply-laundry-drainage-first dehydration-water supply-first washing-discharging-second dehydration-water supply-final washing-discharging-final dehydration.

Explain the movement of the softener in each stroke.

The movement of the softener in the conventional washing machine 100 will be described using Figs. 13 to 16.

Fig. 14 is a cross-sectional view showing a state in which the softening agent flows in the softener automatic discharge device 121 in the conventional washing machine 100. 15 and 16 are cross-sectional views for explaining the movement of the softener in the conventional washing machine 100.

As shown in Fig. 13 and Fig. 14, first, the softener that is put into the softener case 122 before the start of the laundry stroke is subjected to the centrifugal force at the first dehydration stroke after the end of the washing stroke, and as indicated by the arrow a, The moving path 147 moves to the first chamber 148. The softener moved to the first chamber 148 is attached to the outer side wall 156 of the first chamber 148 by the centrifugal force in the region indicated by b until the first dehydration step is completed. In the first washing course after the end of the first dehydration step, the softener moves to the second chamber 150 through the second movement path 149 as indicated by an arrow c.

Next, as shown in Fig. 14 and Fig. 15, the softener is passed through the third movement path 151 to the third chamber by the centrifugal force at the second dehydration step after the end of the first washing course. 152 moves. The softening agent moved to the third chamber 152 is attached to the outer side wall 157 of the third chamber 152 by the centrifugal force in the field indicated by e until the second dehydration stroke is completed.

After the completion of the second dehydration step, the softener passes through the fourth movement path 153 as indicated by an arrow f (see Fig. 14), and as shown in Fig. 16, as the arrow g passes through the outflow passage 154, as indicated by an arrow h The softener outlet 155 flows out and falls between the water tank 103 and the laundry and dewatering tank 104.

However, the configuration of the conventional washing machine 100 shown in Figs. 11 to 16 has the following problems.

At the end of the previous series of operations, the laundry and dewatering tank 104 will stop at any position. Therefore, it is impossible to control which position the softener automatic outflow device 121 and the softener case 122 provided on the inner surface side of the fluid balancer 120 are stopped.

Fig. 17 is a view showing an example of the position of the softener case 122 at the end of a series of operations of the conventional washing machine 100.

In the state of Fig. 17, the softener case 122 is stopped in the vicinity of the water supply port 116a. In these states, it is assumed that the object to be washed 124 is introduced into the washing and dewatering tank 104 to the vicinity of the opening 120a of the fluid balancer 120. In this case, the operation starts and the tap water W is supplied from the water supply port 116a.

As described above, as shown in FIG. 17, one portion of the tap water W is jumped back to the softener automatic outflow device 121 side due to the object to be washed 124. Moreover, the tap water W sometimes enters the softener case 122 via the softener inlet 123 of the fluid balancer 120. Therefore, at the time of water supply, the softening agent in the softener case 122 is mixed with water, and the concentration of the softening agent is lowered, and the problem of the predetermined performance of the softening agent cannot be obtained during the washing course.

The present invention is one which provides a predetermined property of the softening agent during the washing course.

The washing machine of the present invention comprises: a body; a water tank disposed in the body and having a rotatable laundry and dewatering tank therein; a pulsator rotatably disposed at the bottom of the washing and dewatering tank; and fluid balance The device is disposed above the laundry and dewatering tank. Further, the softener automatic outflow device is disposed in the fluid balancer, and causes the softener to flow out into the water tank during the washing stroke; the control portion controls the operation including washing, washing, and dehydrating. Further, the softener inlet is provided in the fluid balancer and communicates with the softener automatic outflow device; the softener is inserted into the opening to cover the opening of the softener inlet; and the bearing is made of a softener The inlet cap is rotated near the opening of the softener inlet.

According to the washing machine of the present invention, even if the water is supplied to the softener in the water supply or the laundry stroke after the start of the operation, the water can be prevented from entering the softener inlet through the softener. Therefore, it is possible to reduce the possibility that the softener in the automatic dispenser of the softener is mixed with water to lower the concentration of the softener. Therefore, the predetermined performance of the softener can be prevented from being lowered during the washing course.

Further, since the softener is placed in the vicinity of the opening of the softener insertion opening, the bearing portion of the softener insertion flap is configured as a detachable softener cartridge for storing the softener.

Therefore, even if the softener automatic outflow device is located on the rear side of the washing machine, that is, below the opening of the upper casing, and stops at a position where it is difficult to put the softener above the softener inlet, the user can also load and unload the softener case. And put in softener. Therefore, the ease of use as in the prior art can be maintained, and water infiltration from the softener can be reduced during the laundry stroke, and the predetermined performance of the softener can be prevented from being lowered.

Moreover, as shown in FIG. 3 and FIG. 4, the outer peripheral portion 26b of the softener insertion opening cover 26 is provided with a cover ridge 29 disposed on the outer side of the insertion port ridge 25. The cover ridge 29 is provided in the vicinity of the surface 26c that abuts against the opening of the softener insertion opening 23 in the softener insertion opening cover 26.

Fig. 5 is a cross-sectional structural view showing the vicinity of the hook portion of the washing and dewatering tank in the vicinity of the center of the hook of the washing machine 50 in the embodiment of the washing machine 50 according to the embodiment of the present invention.

As shown in FIGS. 3, 4, and 5, the hook portion 30 is provided on the surface 26c of the softener inlet cover 26 that faces the softener inlet port 23. A hooking hole 31 for hooking the hooking portion 30 is provided in the softener inlet port 23. Therefore, when the softener insertion opening cover 26 closes the softener insertion opening 23, as shown in Fig. 5, the hooking portion 30 is hooked to the hooking hole 31.

The operation of the washing machine 50 having the above configuration will be described.

The user opens the lid 18, puts the laundry 24 such as laundry into the washing and dewatering tank 4, and opens the power switch disposed in the outer frame 1 of the washing machine, and presses a start button (not shown). Thus, by the motor (drive portion) 7, the washing and dewatering tank 4 is rotated forward and backward to detect the amount of the laundry 24.

Next, the necessary washing amount is displayed on the operation unit (not shown). The user puts the lotion into a predetermined position (in the laundry and dehydration tank 4), opens the softener input port cover 26, and puts in the softener input port 23 (or the softener case 22 can be removed and put in) a predetermined amount. Softener. Then, the softener input port cover 26 is closed, and a predetermined amount of tap water is supplied from the water supply port 16a to the washing and dewatering tank 4 via the water supply valve 16 by the closing cover 18.

When a predetermined amount of tap water is supplied, the pulsator 5 rotates forward and reverse, and the washing stroke of the washed object 24 is performed.

When the laundry stroke of the predetermined time is over, the washing water in the water tank 3 is drained to the outside of the outer frame 1 of the washing machine by the drain valve 15. When the washing water is drained, the washing and dewatering tank 4 is rotated at a high speed (for example, 300 rpm) to perform the first dewatering stroke.

When the first dehydration step is completed, the tap water is again supplied, and the pulsator 5 is rotated in the reverse direction, and the first washing course of the washed object 24 is washed. At the end of the first washing course, the washing water in the water tank 3 is drained to the outside of the washing machine outer frame 1 to perform the second dehydration step (the washing and dehydrating tank 4 is rotated at a high speed by, for example, the number of rotations of the washing and dewatering tank 4: 300 rpm) .

Further, the tap water is supplied to perform the final washing course, and then the washing water in the water tank 3 is drained to perform the third dehydration stroke (the washing and dewatering tank 4 is rotated at a high speed by, for example, the number of rotations of the washing and dewatering tank 4: 800 rpm ).

After the third dehydration step, the operation is completed.

Next, the operation of the softener flowing in the softener automatic outflow device 21 during the operation will be described.

Fig. 6 is a cross-sectional view showing the state in which the softener flows in the softener automatic outflow device 21 in the embodiment of the present invention. Further, Fig. 7A is a cross-sectional view showing a state in which the softener moves toward the first chamber 48 in the softener automatic outflow device 21, and Fig. 7B is a cross-sectional view of the softener moving toward the third chamber 52, Fig. 7C A cross-sectional view showing the appearance of the softening agent from the softener automatic outflow device 21 to the water tank 3.

As shown in Fig. 6 and Figs. 7A to 7C, the softener automatic discharge device 21 is disposed between the outer wall 44 and the inner wall 45 of the fluid balancer 20, and a detachable softener case 22 is provided. At the same time, the first chamber 48 is provided by the softener case 22 via the first movement path 47, and the second chamber 50 is provided via the second movement path 49. The bottom surfaces of the first chamber 48, the second movement path 49, and the second chamber 50 have a downward slope, so that the softener easily flows from the first chamber 48 toward the second chamber 50.

Further, the third chamber 52 is provided via the third movement path 51, and the softener outlet 55 is provided via the fourth movement passage 53 and the outflow passage 54. The bottom surfaces of the third chamber 52, the fourth moving passage 53, and the outflow passage 54 have a downward slope, so that the softener easily flows from the third chamber 52 to the outflow passage 54.

The movement of the softener in the above configuration will be described. First, at the start of the laundry stroke, the softener put into the softener case 22 is centrifugally moved by the first dewatering stroke after the end of the washing stroke, and passes through the first moving path 47 as the arrow a passes over the wall surface of the softener case 22. Move to the first chamber 48 (see Fig. 6 and Fig. 7A).

The softening agent moved to the first chamber 48 is in a state shown by b, and is attached to the outer side wall 56 of the first chamber 48 by centrifugal force until the end of the first dehydration step. After the completion of the first dehydration step, that is, at the time of the first washing course, the softener passes through the inclination of the bottom surfaces of the first chamber 48, the second movement passage 49, and the second chamber 50 as indicated by an arrow c. The second movement path 49 moves to the second chamber 50 (see Fig. 6).

Next, the softener moves to the third chamber 52 through the third movement path 51 on the wall surface as indicated by an arrow d by the centrifugal force at the second dehydration step after the end of the first washing course. The softener that has moved to the third chamber 52 is in a state shown by e, and is attached to the outer side wall 57 of the third chamber 52 by centrifugal force until the second dehydration step is completed (see FIGS. 6 and 7B). .

After the completion of the second dehydration step, that is, at the time of the final cleaning stroke, the softener passes through the fourth movement path 53 as indicated by an arrow f by the inclination of the bottom surfaces of the third chamber 52 and the fourth movement path 53. Further, the inclination of the bottom surface provided on the fourth moving path 53 and the outflow path 54 passes through the outflow path 54 as indicated by an arrow g, and then flows out from the softener outflow port 55 to the water tank 3 as indicated by an arrow h. Between the laundry and the dewatering tank 4 (see Fig. 6 and Fig. 7C).

As described above, according to the washing machine 50 of the present embodiment, the softener insertion opening cover 26 that covers the softener insertion opening 23 is provided above the softener insertion opening 23 that communicates with the softener cartridge 22 that stores the softener. In this way, even before the start of the operation and during the washing course, the softener insertion opening cover 26 is covered with the softener insertion opening 23, and water or the like is scattered from above the softener insertion opening 23, and the scattered water can be prevented. The softener inlet 23 enters the softener box 22 (water infiltration).

Fig. 8 is a view showing a state in which the softener case 22 is located in the vicinity of the water supply port 16a in the washing machine 50 according to the embodiment of the present invention.

As shown in Fig. 8, it is assumed that the softener case 22 is stopped in the vicinity of the water supply port 16a, and the laundry 24 is put into the washing and dewatering tank 4 in the vicinity of the opening 20a of the fluid balancer 20. In this state, the operation is started, and the tap water W is supplied from the water supply port 16a. Even if one part of the tap water W is scattered by the object 24 to be applied to the softener inlet 23, the tap water W can be prevented from entering the softener inlet. 23 or within the softener cartridge 22. Therefore, it is possible to reduce the possibility that the softener in the softener case 22 is mixed with water to lower the concentration of the softener, and it is possible to prevent the softener from having a predetermined performance degradation.

Further, in the washing machine 50 of the present embodiment, as shown in Figs. 3 and 4, the insertion port ridge 25 is provided around the softener inlet port 23. Thereby, even if water flows from the periphery of the softener inlet 23 to the softener inlet 23, the inlet lip 25 can block the water flowing to the softener inlet 23, thereby preventing water from being horizontally applied from the softener inlet 23. The softener input port 23 is entered. Further, when the tap water W is supplied from the water supply port 16a, it is possible to prevent not only the water scattered around the softener inlet 23 but also the softener inlet 23 from entering the softener inlet 23 from the horizontal direction. Thereby, the softening agent in the softener case 22 can be further reduced in mixing with water, the concentration of the softening agent can be lowered, and the predetermined performance of the softening agent can be prevented from being lowered.

Further, in the washing machine 50 of the present embodiment, as shown in FIGS. 3 and 4, the softener insertion opening cover 26 is provided with a cover ridge 29 disposed on the outer side of the insertion port ridge 25. Thereby, the water flowing in the horizontal direction can be blocked by the two ridges of the cover rib 29 and the insertion port ridge 25, so that the water can be prevented from entering the softener insertion opening 23 from the horizontal direction.

Further, when the softener insertion opening cover 26 is made of a resin such as polypropylene, ABS, polyethylene, or polycarbonate, it may be inserted into the mouth ridge 25 and soft due to thermal deformation during molding or deformation during actual use. There is a possibility that a gap is formed between the agent input flaps 26. However, in the washing machine 50 of the present embodiment, by providing the cover ridges 29, the deformation strength of the softener insertion opening cover 26 can be increased, and the possibility of deformation of the softener insertion opening cover 26 can be reduced. Thereby, the adhesion between the upper surface 25a of the inlet ridge 25 and the softener supply opening cover 26 can be improved, and the water can be prevented from entering the softener insertion opening 23 from the horizontal direction.

As described above, according to the washing machine 50 of the present embodiment, the softening agent in the softener case 22 can be further mixed with water to lower the concentration of the softening agent, and the predetermined performance of the softening agent can be further prevented from being lowered.

Fig. 9 is a view showing another cross-sectional configuration of the softener insertion opening cover 26 in the washing machine 50 according to the embodiment of the present invention.

As shown in Fig. 9, the softener can be placed in the flap 26 so as to be substantially vertically convex and substantially convex. According to this configuration, the flat portion of the softener into the flap 26 can be reduced, and the deformation strength can be improved. Therefore, the deformation of the softener into the flap 26 can be further prevented. Further, the adhesion between the upper surface 25a of the inlet ridge 25 and the softener inlet cover 26 can be further improved, and the water can be prevented from entering the softener inlet 23 from the horizontal direction.

Further, the water dropped onto the upper surface of the softener insertion opening cover 26 is dripped by the softener insertion opening cover 26. Therefore, it is difficult to deposit the dripping water on the upper surface of the softener insertion opening cover 26. Thereby, the possibility of the presence of water in the vicinity of the softener inlet 23 can be reduced, and the possibility that water enters the softener inlet 23 can be reduced.

Further, in the washing machine 50 of the present embodiment, as shown in Figs. 4 and 5, the hooking portion 30 is provided on the surface 26c of the softener insertion opening 26 facing the softener insertion opening 23, and is put into the softener. A hooking hole 31 for hooking the hook portion 30 is provided in the opening 23. Thereby, when the softener insertion opening cover 26 closes the softener insertion opening 23, since the hooking portion 30 is hooked to the hooking hole 31, the softener insertion opening cover 26 is closer to the upper surface portion 25a of the input opening ridge 25. . Further, as shown in Fig. 5, if the hooking hole 31 is provided as a hole toward the lower side, for example, it can be molded in a molding die by using a punching die in the vertical direction, and it is not necessary to use a lateral sliding die for molding. . Therefore, the advantages in terms of production method or cost are good.

Further, even when a large amount of water flows to the vicinity of the softener inlet 23, it is possible to prevent the softener inlet flap 26 from being pushed up by the flowing water, and is separated from the inlet lip 25. Therefore, the amount of water that enters the softener inlet 23 from the contact surface between the softener insertion opening 26 and the upper surface portion 25a of the inlet rib 25 can be further reduced, and the possibility of water entering the softener inlet 23 can be further reduced.

Fig. 10A is a view for explaining the configuration of the hooking hole 31 in the washing machine 50 according to the embodiment of the present invention. Further, Fig. 10B is a view for explaining the configuration of the hooking hole 41 of the comparative example in the embodiment of the present invention.

In the comparative example shown in Fig. 10B, the hooking hole 41 is formed in the outer peripheral wall 25b of the inlet rib 25. In this case, the softener in the softener case 22 may flow countercurrently above the softener supply port 23 via the hooking hole 41 by the centrifugal force of the high-speed rotation of the washing and dewatering tank 4 in the first dehydration step. However, there is a possibility that a predetermined amount of the softener cannot flow in the softener automatic discharge device 21, and the predetermined performance of the softener cannot be obtained.

However, in the present embodiment, as shown in Figs. 3, 4, 5, and 10A, the hook hole 31 is formed in the vicinity of the side wall 25c or the inner peripheral wall 25d of the inlet rib 25. Thereby, in the first dehydration step, it is possible to prevent the softening agent from flowing back into the softener insertion opening 23 via the hooking hole 31. Therefore, since a predetermined amount of the softener flows in the softener automatic discharge device 21, the predetermined performance of the softener can be obtained.

Further, in the washing machine 50 of the present embodiment, as shown in Figs. 2 and 3, a bearing portion 27 for rotating the softener insertion opening cover 26 is provided in the vicinity of the upper surface 25a of the insertion port ridge 25. Thereby, the softener insertion opening 26 and the shaft portion 26d of the softener insertion opening cover 26 can be disposed above the softener insertion opening 23. Thereby, the softener case 22 of the softener automatic outflow device 21 is detachably constructed.

Therefore, as shown in Fig. 8, even if the softener automatic outflow device 21 is located on the rear side of the outer frame 1 of the washing machine, that is, below the rear surface 17b of the opening portion 17a of the upper casing 17, it is difficult to pass the softener supply port 23 The softener is poured into the upper position, and the user can load and unload the softener case 22 and put in the softener. Therefore, it is possible to maintain the same usability as the conventional one, and it is possible to reduce the entry of water from the upper side of the softener inlet 23 during the laundry stroke.

Further, in the washing machine 50 of the present embodiment, as shown in Figs. 2 and 3, the shaft portion 26d of the softener insertion opening cover 26 is placed in the softener insertion opening cover 26, and the center side of the fluid balancer 20 is at the circumference. In the direction, the swirl restricting portion 28 is provided so that the softener insertion opening cover 26 is restricted from being rotated by 180 or more. Therefore, even if the softener insertion opening cover 26 is opened, as shown in Fig. 4, the softener insertion opening cover 26 is inclined toward the softener insertion opening 23, so that even when the user puts the softening agent into the softener insertion opening 23, it is soft. The agent flows to the softener inlet cap 26, and the softener also flows to the softener inlet port 23. Therefore, the user not only flows the softener to the softener insertion opening 23, but also flows into the softener insertion opening 23 even when the softener is introduced into the mouthpiece 26. Therefore, the area of the softener can be increased. Thereby, the input of the softener becomes easy, and the usability is improved.

Further, when the user puts in the softener from the softener insertion opening 23, the softener insertion opening cover 26 does not open to 180° or more even if the softener insertion opening cover 26 is forgotten to be closed. Further, the shaft portion 26d of the softener insertion opening cover 26 is disposed in the circumferential direction on the center side of the fluid balancer 20 at the softener insertion opening cover 26. Thereby, for example, even if the user forgets to close the softener insertion opening cover 26, the softener insertion opening cover 26 can be moved to close the softener insertion opening 23 when the centrifugal force is applied to the softener insertion opening cover 26 in the first dehydration stroke after the washing stroke. Above.

Further, as shown in Figs. 3 and 4, the outer side 26b or the inner side of the surface of the softener inlet cover 26 that abuts against the softener inlet 23 is provided with a lid ridge 29, whereby the softener flows to the softener inlet flap. At 26 o'clock, the cover rib 29 will become a retaining wall. Thereby, it is possible to reduce leakage of the softener from the softener insertion opening cover 26.

As described above, according to the present invention, the predetermined performance of the softening agent can be obtained in the washing course, and therefore, it can be used not only for a washing machine for household use but also for a washing machine for business use.
