A first flow path 108 a in the vertical direction is formed inside the first pipe portion 108, and a second flow path 109 a in the front-rear direction, that is, in the lateral direction is formed inside the second pipe portion 109. The first flow path 108a and the second flow path 109a constitute a flow path 107a of the discharge port 107. As shown in FIG. 5( b ), the second pipe portion 109 of the discharge port portion 107 is connected to the supply pipe 200.

Mounting pieces 110 having mounting holes 110a are formed on the front side, right side, and rear side of the detergent box 100. The mounting piece 110 is used when fixing the detergent box 100 to the upper panel 12.

3, 4, 6(a), (b), and (c), the anti-clogging member 300 is formed of, for example, a resin material, and includes a filter portion 310 and an anti-clogging portion 320 integrated with the filter portion 310 .

The filter part 310 is formed approximately in a cylindrical shape with a bottom, and the front part of its peripheral surface is recessed to the rear except for the upper end part, thereby forming a flat front surface 310a and a flat surface orthogonal to the front surface 310a at the front part.的步面310b. A handle hole 311 for hooking fingers is formed on the upper part of the front surface 310a of the filter part 310. The circumferential surface of the filter portion 310 has a tapered shape that slightly expands upward, and at its upper end, the expanded angle becomes larger so as to easily catch the liquid detergent.

In the corner portion between the circumferential surface and the bottom surface of the filter portion 310, a plurality of first holes 312 having a longitudinally long slit shape are formed so as to be arranged in the circumferential direction. In addition, a plurality of circular small second holes 313 are formed on the bottom surface of the filter portion 310.

The clogging prevention portion 320 includes a rib 321 extending downward from the bottom surface of the filter portion 310 and having a cross-shaped cross section, and a disc-shaped receiving portion 322 formed at the top end of the rib 321. At the top end of the rib 321, two right and left rectangular circulation ports 323 penetrating in the front-rear direction are formed.

As shown in FIG. 3, the clogging prevention member 300 is inserted into the detergent box 100 from the input port 101. At this time, the clogging prevention portion 320 passes through the opening 105 of the filter housing portion 103 and enters the interior of the detergent box 100.

When the clogging prevention member 300 is completely inserted into the detergent box 100, that is, when the installation of the clogging prevention member 300 to the detergent box 100 is completed, as shown in FIG. 4, the filter part 310 is housed in the filter housing part 103, and the clogging prevention part The tip of 320 enters the flow path 107a of the discharge port 107, that is, the first flow path 108a. The lower end surface of the first flow channel 108a is covered from above by the receiving portion 322 of the clogging prevention portion 320. The two flow ports 323 of the anti-clogging part 320 are located in front of the entrance of the second flow path 109 a to the discharge port 107.

The liquid detergent is put into the detergent box 100 from the input port 101 by the user in advance. The injected liquid detergent flows into the detergent box 100 through the first hole 312 and the second hole 313 of the filter part 310 and the hole 104 and the opening part 105 of the filter housing part 103.

The injection port 101 has a relatively large opening area for easy injection of liquid detergent. Therefore, foreign matter may enter the detergent box 100 from the input port 101 by mistake when the liquid detergent is input. The foreign matter entering the detergent box 100 cannot pass through the first hole 312 and the second hole 313 of the filter part 310 and is captured by the filter part 310.

The fully automatic washing machine 1 performs washing operations in various operation modes. During the washing operation, the washing process, the intermediate dehydration process, the rinsing process and the final dehydration process are executed in order.

During the washing process and the rinsing process, the pulsator 24 rotates to the right and left in a state where water is stored in the washing and dehydration tub 22. Through the rotation of the pulsator 24, a water flow is generated in the washing and dehydrating tub 22. In the washing process, the laundry is washed by the generated water stream and the detergent contained in the water. In the rinsing process, the laundry is rinsed by the generated water stream.

In the intermediate dehydration process and the final dehydration process, the washing and dehydration barrel 22 and the pulsator 24 rotate at a high speed integrally. The laundry is dehydrated by the centrifugal force generated in the washing and dehydrating tub 22.

When water is supplied in the washing process, the liquid detergent is automatically put into the washing and dehydrating tub 22 by the automatic input mechanism 60. At this time, first, the three-way valve 62 is switched to a state in which the supply pipe 200 and the supply pump 64 communicate. When the supply pump 64 operates, the liquid detergent in the detergent box 100 is discharged from the discharge port 107 by the action of the pump. At this time, in the first flow path 108a of the discharge port 107, the liquid detergent flowing in front of the flow port 323 of the rib 321 passes through the flow port 323 to the entrance of the second flow path 109a.

The liquid detergent discharged from the discharge port 107 passes through the supply pipe 200, the three-way valve 62, and the supply pump 64 as shown by the broken arrow in FIG. 2 and is sent to the detergent supply path 65. The supply pump 64 is operated for a predetermined time, and thereby a predetermined amount of liquid detergent is stored in the detergent supply path 65.

Next, the three-way valve 62 is switched to a state in which the auxiliary water supply passage 63 and the supply pump 64 are in communication, and the auxiliary valve 53 is opened. As shown by the solid arrow in FIG. 2, the water from the faucet passes through the auxiliary water supply path 63, the three-way valve 62, and the supply pump 64 to flow to the detergent supply path 65 to flush away the liquid detergent. The liquid detergent washed away by the water is injected into the washing and dehydrating tub 22 from the supply port 65a of the detergent supply path 65 together with the water, as shown by the one-dot chain arrow in FIG. 2. When the injection of the liquid detergent into the washing and dehydrating tub 22 is completed, the sub valve 53 is closed.

Then, water supply into the washing and dehydrating tank 22 is performed. The main valve 52 is opened, and the water from the faucet flows through the main water supply channel 54 and is discharged from the water injection port 54a into the washing and dehydrating tub 22. When the water level in the washing and dehydrating tub 22 reaches a predetermined washing water level, the main valve 52 is closed, and the water supply ends.

Then, during the use of the fully automatic washing machine 1, the solidified liquid detergent may be accumulated in the flow path 107a of the discharge port 107 of the detergent box 100, that is, the first flow path 108a. For example, when the detergent box 100 is left empty for a long time, the liquid detergent remaining in the first flow path 108a will easily solidify into a gel form due to long-term contact with air. If this situation occurs repeatedly, The solidified liquid detergent will gradually increase, and the first flow path 108a will be blocked.

In this embodiment, the tip of the clogging prevention part 320 enters the first flow path 108a. Therefore, as shown by the one-dot chain line in FIG. 4, the solidified liquid detergent adheres to the rib 321 or accumulates on the receiving portion 322 to be caught by the top end of the clogging prevention portion 320. In other words, the tip of the clogging prevention part 320 functions as a catching part of the solidified liquid detergent.

In this way, when the solidified liquid detergent blocks the flow path 107a of the discharge port 107, that is, the first flow path 108a, the user lifts the clogging prevention member 300 upward and removes it from the detergent box 100. At this time, the user can grasp the clogging prevention member 300 by hooking the handle hole 311 with a finger and grasping the upper end portion of the filter portion 310.

When the anti-clogging member 300 is detached from the detergent box 100, the top end of the anti-clogging portion 320 is taken out to the outside along with the solidified liquid detergent. As a result, the solidified liquid detergent is removed from the first flow path 108a. Then, by washing the top end of the clogging prevention part 320, the solidified liquid detergent is removed from the top end.

When the cleaning of the anti-clogging member 300 is completed, the user installs the cleaned anti-clogging member 300 in the detergent box 100.

As described above, according to the present embodiment, the automatic input mechanism 60 has the clogging prevention member 300. The anti-clogging member 300 is inserted into the detergent box 100 from the outside of the box body 10 in an accessible manner. In the inserted state, the top end of the anti-clogging member 300 enters the flow path 107a of the discharge port 107 and is solidified in the flow path The liquid detergent in 107a is captured by the tip of the anti-clogging member 300. Thus, when the solidified liquid detergent is accumulated in the flow path 107a of the discharge port 107, the solidified liquid detergent can be easily removed from the outside of the fully automatic washing machine 1, and the discharge port 107 can be easily prevented from being damaged. Blocked.

In addition, according to the present embodiment, the clogging prevention member 300 is detachably attached to the input port 101 to capture foreign matter entering the detergent box 100 from the input port 101 and the filter unit 310 integrated with the filter unit 310 to An anti-clogging part 320 that captures the solidified liquid detergent at the tip part is constituted. Thus, it is possible to prevent foreign matter from entering the detergent box 100 from the input port 101. Furthermore, only by attaching the filter portion 310 to the input port 101, the tip portion of the clogging prevention portion 320 can be installed in the flow path 107a of the discharge port portion 107. Furthermore, the input port 101 for inputting the liquid detergent can be used as an insertion port through which the clogging prevention member 300 is inserted into the detergent box 100.

Furthermore, according to the present embodiment, the following structure is adopted: the discharge port 107 is formed to extend downward from the bottom surface of the detergent box 100 and then be bent laterally and have a first flow path 108a in the vertical direction and a second flow path 109a in the lateral direction, and The tip portion of the clogging prevention portion 320 enters into the first flow path 108a from above, and has a receiving portion 322 covering the lower end surface of the first flow path 108a from above. As a result, the liquid detergent solidified in the first flow path 108a can be blocked from below by the receiving portion 322. Therefore, when the tip portion of the clogging prevention portion 320 is lifted upward in the first flow path 108a, the solidified liquid detergent It is not easy to fall from the tip. Therefore, it is easy to recover the solidified liquid detergent through the anti-clogging member 300.

As mentioned above, the embodiment of the present invention has been described, but the present invention is not limited to the above-mentioned embodiment and the like at all. In addition, the embodiment of the present invention may be modified in various ways other than the above.

For example, in the above-mentioned embodiment, a structure is adopted in which the clogging prevention portion 320 of the clogging prevention member 300 includes a rib 321 having a cross-shaped cross section and a disc-shaped receiving portion 322 formed at the tip of the rib 321. However, the clogging prevention part 320 only needs to be able to capture the solidified liquid detergent at its tip, and may have a structure different from the above-mentioned structure.

For example, in the configuration example of FIG. 7( a ), the clogging prevention member 300A has the clogging prevention portion 330 integrated with the filter portion 310. The clogging prevention portion 330 is composed of a cylindrical main body portion 331 and a disc-shaped bottom portion 332 that closes the opening of the bottom surface of the main body portion 331. The bottom 332 corresponds to the receiving part of the present invention. An opening 333 is formed on the rear side of the lower end of the main body 331. The opening 333 faces the entrance of the second flow path 109a. A plurality of rectangular circulation ports 334 are formed in the main body 331. The liquid detergent injected from the input port 101 and flowing out from the second hole 313 of the filter part 310 to the inside of the clogging prevention part 330 flows through the circulation port 334 into the detergent box 100. In addition, a part of the liquid detergent in the detergent box 100 flows through the circulation port 334 to the inside of the clogging prevention part 330 and flows through the opening part 333 to the second flow path 109a.

In the clogging prevention member 300A of FIG. 7(a), the liquid detergent solidified in the first flow path 108a can also be captured by the tip portion of the clogging prevention portion 330.

In addition, in the above-described embodiment, the clogging prevention member 300 adopts a structure in which the clogging prevention portion 320 and the filter portion 310 are integrated. However, for example, as shown in the structural example of FIG. 7(b), the clogging prevention member 300B may have a structure that does not include a filter unit.

In the structural example of FIG. 7(b), the filter part 310 is provided as a separate filter member 310, and is accommodated in the filter accommodating part 103 of 100 A of detergent boxes. In the detergent box 100A, the discharge port portion 107 is formed behind the filter housing portion 103. In addition, on the upper surface of the detergent box 100A, a circular insertion port 111 is formed behind the input port 101.

The clogging prevention member 300B is composed of a clogging prevention portion 340 and a cap portion 350 that blocks the insertion port 111.
