In addition, a motor 7 for selectively rotating the washing tank 3 and the pulsator 5 is installed at one lower end side of the water storage tank 2, and a rotational force is provided at the lower end of the water storage tank 2 at the washing tank and the pulsator. Clutch (8) for selectively transmitting is installed.

Further, pulleys 7a and 8a are provided at the shaft end of the motor 7 and the shaft end of the clutch 8, respectively, and a timing belt 9 is wound between the pulleys.

In addition, a water supply line 10 connected to an outside of the main body 1 to supply the washing water to the washing tank 3 is connected to the outside, and the washing water is supplied to the upper side of the washing tank 3 by water. The detergent container 13 is automatically provided with detergent. In addition, the lower end side of the reservoir (2) is provided with a drain pipe 11 for discharging the washing water discharged through the through hole (3a) of the washing tank during washing, rinsing, dehydration administration to the outside.

And, the upper portion of the washing tank (3) is provided with a balance weight (20) to prevent the vibration of the washing tank when dewatering along its circumferential surface.

Meanwhile, the fabric softener is added during the rinsing process to gently release the laundry after washing and prevent static electricity. In particular, when the laundry is a wool type, the addition of a fabric softener is almost essential.

To this end, if there is a method to provide a separate space for storing the fabric softener in the detergent container 13 and to automatically inject the fabric softener by the wash water supplied when rinsing, the fiber on one side of the balance waiter 20 There is a method of automatically adding a fabric softener by using a centrifugal force during dehydration with a softener input device.

Among these, the latter fabric softener injecting device will be described in detail as follows.

As shown in FIG. 2, the fabric softener injector 30 has an inlet 34 through which the user can inject the fabric softener on an upper side of the balance waiter 20, and a balance waiter below the inlet. A plurality of storage chambers (31, 32, 33) continuous along the inner space of the.

On the other hand, the balance waiter 20 is composed of two upper and lower bodies are joined to each other by high frequency welding. Therefore, the fabric softener input device 30 is also composed of two upper and lower bodies based on the welding surface.                         

Figure 3 shows a part of the lower body of the balance waiter to show the structure of the fabric softener dosing device.

As shown in FIG. 3, the storage compartments 31, 32, 33 are partitioned from each other by a plurality of partitions 21, 22 and provide a path of movement with the storage of the fabric softener. That is, the storage compartment is provided directly below the inlet, the first storage compartment 31 for storing the first time the supply of the fabric softener, and the second storage compartment forming the S-shaped flow path surrounding the back of the first storage chamber 32 and a third storage chamber 33 provided at a rear side of the second storage chamber and having a discharge port 35 that is finally introduced between the water storage tank and the washing tank on one side of the lower side of the second storage chamber.

In addition, a first through hole 36 is formed at an upper side of the rear wall of the first storage chamber 31 and serves as a movement path of the fabric softener on an upper side of the partition wall 21 partitioning the first storage chamber and the second storage chamber. A second through hole 37 is formed at an upper side of the partition wall 22 that divides the second storage chamber 32 and the third storage chamber 33.

At this time, the first storage chamber 31 is deep enough to hold a sufficient amount of fabric softener, the second storage chamber 32 is shallower than the depth of the first storage chamber, but the third storage chamber It is inclined downward toward the (33) side to facilitate the movement of the fabric softener.

On the other hand, when the rotation direction of the washing tank in the clockwise direction during dehydration, the first storage chamber 31, the second storage chamber 32 and the third storage chamber 33 should be located on the right side in the drawing in order, The first through hole 36 and the second through hole 37 should be provided at the upper left side of the partition wall, respectively.                         

Referring to the operation of the fabric softener input device configured as described above are as follows.

First, if the user puts the appropriate amount of the fabric softener through the inlet 34 before the washing proceeds, the fabric softener is stored in the first storage chamber (31). Thereafter, as the washing process is completed and the rinsing process is performed, the fabric softener in the first storage chamber is moved to the outlet 35 through the second storage chamber 32 and the third storage chamber 33 by centrifugal force. do.

In detail, when the washing is completed, the first rinsing proceeds, and then the first liver is dehydrated. At this time, the fabric softener in the first storage chamber 31 is drawn to the rear surface by centrifugal force to move to the second storage chamber 32 through the first through-hole 36. Subsequently, the second simple dehydration proceeds after the second rinse. At this time, the fabric softener in the second storage chamber 32 is moved to the rear side by centrifugal force to move to the third storage chamber 33 through the second through hole 37, After moving along the rear surface, the discharge port 35 provided at the bottom is finally discharged into the space between the washing tank and the reservoir.

Next, the fabric softener supplied between the washing tank and the water storage tank is diluted in the washing water supplied as the third rinsing proceeds, and is continuously added to the laundry through the through-hole of the washing tank to perform a predetermined function.

However, the fabric softener injector as described above, when the water level of the wash water supplied during rinsing is low, there is a problem that the fabric softener solidifies on the wall of the washing tank or the reservoir.                         

In other words, the fabric softener injected during the last rinse should flow down the outer wall of the washing tank and be diluted with the washing water rising by the centrifugal force and supplied into the washing tank. Washing water will not reach the fabric softener above the inner wall of the reservoir. In this case, the fabric softener is solidified on the wall of the washing tank or the water storage tank so that it cannot perform its function properly.

In addition, the coagulant softener is a major contaminant of laundry in the next washing process.

The present invention has been made to solve the above problems, an object of the present invention is provided on one side of the balance waiter in the washing machine for automatically discharging the fabric softener by centrifugal force, even if the washing level is low all of the fabric softener discharged It is to provide a fabric softener injector of the washing machine to maximize the performance of the fabric softener by being diluted in the wash water.

In order to achieve the above object, the fabric softener injector of the washing machine according to the present invention is at least one that can be moved by the centrifugal force at the time of dehydration through a through hole formed in the partition wall at the same time partitioned with each other by a partition on the inner side of the balance waiter Two or more storage chambers, an upper opening of one of the storage chambers, and a fiber softener to be first introduced, and a balance chamber is provided along the balance roller from the storage chamber in which no openings are provided. It is provided on one side of the balance waiter so as to communicate with the discharge flow path, and the softening agent and at the same time is provided inside the washing tank to prevent the fabric softener is directly injected into the washing tank to be diluted and added to the pumped wash water during rinsing And a feed suppression means.

At this time, it is preferable that the discharge passage is lowered in height toward the input suppression means so as to smoothly move the fabric softener.

And, the input suppression means may use a foreign matter sieve provided on one side of the washing tank.

On the other hand, in order to suppress the movement of the fabric softener through the discharge flow path during dehydration, the flow direction of the fabric softener through the discharge flow path is preferably the same as the rotation direction of the washing tank during dehydration, for example, the flow direction of the fabric softener and the washing tank. The direction of rotation of is clockwise.

Hereinafter, with reference to the accompanying drawings, the fabric softener injector of the washing machine according to a preferred embodiment of the present invention will be described in detail as follows.

First, Figure 4 is a plan view showing a fabric softener input device of the washing machine according to an embodiment of the present invention, Figure 5 is a perspective view showing a part of FIG.

On the other hand, with respect to the general configuration of the washing machine described above will be omitted later.

As shown in FIG. 4, the fabric softener injector 100 of the washing machine according to an embodiment of the present invention includes a plurality of storage chambers 111, 112, and 113 provided on one side of the balance waiter 20 and among the storage chambers. An inlet port 114 provided at an upper portion of the one 111 for the user to first input the fabric softener, a discharge passage 120 communicating with the storage chamber 113 in which the fabric softener is finally discharged from the storage chamber, and It is in communication with the discharge passage and at the same time in communication with the interior of the washing tank is made of the input suppression means 130 to prevent direct input of the fabric softener to the laundry.

The storage compartment is located below the inlet 114, the first storage chamber 111, the first softening chamber is stored, the first storage chamber 111, the third storage chamber 113, one end of the discharge passage 120 is in communication with the first It consists of the 2nd storage chamber 112 which forms the S-shaped flow path of a fiber softener between a 1st storage chamber and a 3rd storage chamber. At this time, the storage chamber is rotated from the first storage chamber to the third storage chamber so that the fabric softener can move from the first storage chamber 111 to the third storage chamber 113 by centrifugal force due to the rotation during dehydration. In addition, the second storage chamber 112 is located at the rear of the first storage chamber 111 from the center of rotation of the washing tub, and the third storage chamber 113 is the second storage from the rotation center of the washing tub. Located behind the seal 112.

On the other hand, the discharge passage 120 is preferably formed in the clockwise direction from the third storage chamber 113 to the input suppression means 130. This assumes that the rotational direction when the washing tank is dewatered is clockwise, so that the fabric softener on the third storage chamber 113 or the discharge passage 120 is prevented from moving to the input suppression means 130 when dewatering. It is for. That is, when some of the fabric softener is introduced into the washing tank through the input suppression means 130 during dehydration, the fabric softener can only be directly added to the laundry, and in this case, damage to the laundry occurs.

Of course, if the rotation direction of the washing tank in the dehydration counterclockwise direction, the discharge passage should also be formed counterclockwise according to the rotation direction of the washing tank.

The input suppressing means 130 is made of a mesh structure having a small mesh as the fabric softener is a fluid having a certain viscosity, thereby preventing the fabric softener from being directly injected into the laundry. At this time, the fabric softener of the input inhibiting means 130 is diluted in the wash water pumped to the height of the input inhibiting means by the rotation of the pulsator or the washing tank during rinsing, and thus may be introduced into the laundry.

5 is a perspective view showing a portion of the lower body of the balance waiter to show the internal structure of the fabric softener injector according to the present invention in detail.

As shown in FIG. 5, the storage compartments are partitioned from each other by a plurality of partitions 21 and 22 on one side of the balance waiter 20. At this time, a first through-hole 116 serving as a moving passage of the fabric softener is formed in an upper portion of one side of the partition wall 21 partitioning the first storage chamber 111 and the second storage chamber 112, and the second storage chamber and A second through hole 117 is also formed in an upper portion of one side of the partition wall 22 partitioning the third storage chamber 113.

In addition, the input suppression means 130 is coupled to the installation groove 23 formed in the inner diameter portion of the other side of the balance waiter so as to communicate with the inside of the washing tank. At this time, the input suppression means 130 should extend down from the lower end of the balance waiter 20 by a predetermined length, that is, the length of the foreign matter sieve (not shown) that is usually provided in the balance waiter.                     

In addition, the discharge passage 120 is provided between the left end of the input suppression means 130 from the lower end of the right wall of the third storage chamber 113. At this time, the discharge passage 120 is downward from the one end 121 in communication with the third storage chamber 113 to the other end 122 in communication with the input suppression means 130 for the smooth movement of the fabric softener. It is preferable to incline at an angle and generate height difference.

On the other hand, the discharge passage 120 is a kind of channel having an open upper surface, the cross-sectional shape is composed of a letter or letter.

The operation of the fabric softener input device configured as described above is as follows.

First, when the user inputs the appropriate amount of the fabric softener through the inlet 114 before the washing proceeds, the fabric softener is stored in the first storage chamber (111).

Next, when the washing administration is completed, the first rinsing proceeds, after which the first liver is dehydrated. At this time, the fabric softener in the first storage chamber 111 is drawn to the partition wall 21 by the centrifugal force to move to the second storage chamber 112 through the first through-hole 311. Subsequently, a second simple dehydration proceeds after the second rinsing proceeds, and the fabric softener in the second storage compartment 112 is directed to the partition wall 22 by the centrifugal force, and the third through the second through hole 117. It moves to the storage room 113. At this time, the fabric softener of the third storage chamber is suppressed in the clockwise direction as the washing tub rotates in the clockwise direction. Accordingly, the movement of the fabric softener in the third storage chamber 113 toward the discharge flow path 120 or the residual fiber softener in the discharge flow path toward the input suppression means 130 is suppressed.                     

Next, during the water supply for the third rinsing after the second simple dehydration is completed, the fabric softener of the third storage chamber 113 is moved to the input suppression means 130 along the discharge flow path 120, the discharge flow path The movement is made much smoother as the inclined downward according to the moving direction of the fabric softener. At this time, the fabric softener of the input inhibiting means 130 is caught by the network structure having a dense mesh, so that the phenomenon of falling into the washing tank due to its own weight does not occur.

Next, while the water supply is completed and the rinsing proceeds while the pulsator or the washing tank is reversed left and right, the fabric softener of the input inhibiting means 130 is diluted in the pumped wash water. At this time, the fabric softener diluted in the wash water and lowered in viscosity is introduced into the laundry through the input suppression means, thereby performing its original function.

Therefore, even if the level of the wash water supplied when rinsing is low, the fabric softener input device of the washing machine according to the present invention may be diluted in the whole amount by the wash water pumped during rinsing by feeding the fabric softener into the washing tank. This is because, when rinsing, the pulsator only rotates to generate water flow, or the washing tank rotates to generate water flow, so that the washing water is usually pumped up to the height of the foreign matter filtering net to filter foreign matter.

Next, Figure 6 is a plan view showing a fabric softener injecting device of a washing machine according to another embodiment of the present invention, it is characterized in that the foreign matter filtering net is applied as the input suppression means.

As shown in FIG. 6, a foreign matter strainer 135 is provided at an inner diameter portion facing the storage chamber of the balance waiter 20. The foreign matter sieve 135 is provided in the installation groove 25 formed in the inner diameter portion of the balance waiter 20 to collect various foreign matters separated from the washing water during the washing stroke, which is also a network having a predetermined mesh Is done. Therefore, the effect of delaying and suppressing the input of the fabric softener can be seen, and thus it can be applied as an input suppressing means.

In this case, the discharge passage 140 must extend from the third storage chamber 113 to one end of the foreign matter sieve 135.

On the other hand, other features of the fabric softener injecting device according to another embodiment of the present invention, for example, the structure of the storage chamber or the formation direction and cross-sectional structure of the discharge passage is the same as that of the above-described embodiment.

The fabric softener input device of the washing machine according to the present invention provides the following effects.

First, according to the present invention, as the fabric softener is completely diluted in the wash water through the input inhibiting means communicating with the inside of the washing tank and finally added to the laundry, it is possible to prevent the fabric softener from solidifying the wall of the washing tank or the storage tank. . Thus, contamination of laundry due to the coagulated fabric softener can be prevented.

Secondly, according to the present invention, the fabric softener can be prevented from being directly added to the laundry, thereby preventing damage to the laundry.
