It has the function to produce | generate and the function to transfer the produced | generated dissolved detergent liquid, It is characterized by the above-mentioned.

  According to the present invention, the powder detergent is sent while being well stirred by the spiral collar, so the time is shortened. Further, since a siphon mechanism for flowing a detergent solution is unnecessary, the structure is simple.

  Embodiments of the present invention will be described with reference to the drawings.

  First, the outline of the washing machine will be described in order from FIG. 1, FIG. 2, FIG. 3, and FIG.

  The washing machine shown in FIG. 1 is a drum type washing machine. The drum-type washing machine body 1 has an operation panel 2 on the upper front side. A detergent dissolving device 3 is provided in the operation panel 2.

  As shown in FIG. 4, the detergent dissolving device 3 is stored in a freely retractable manner in a storage unit 4 provided in the washing machine body 1.

  The detergent dissolution apparatus 3 has upper / lower body cases. The upper body case 10 and the lower body case 11 are aligned vertically. The upper / lower body case is coupled by a fastening screw (not shown). The packing 12 as shown in FIG. 3 is interposed in the periphery of the upper and lower mating surfaces, and the watertightness of the mating surfaces is maintained.

  The detergent dissolution chamber 13 is provided on the upper and lower mating surfaces of the upper / lower body case. The detergent dissolution chamber 13 is a cylindrical space that is long in the lateral direction. A semicircular space formed in the upper / lower body case is combined to create a cylindrical space.

  The detergent stirring rotator 14 is rotatably placed so as to lie in the detergent dissolution chamber 13. The detergent stirring rotator 14 has a spiral collar 15. The spiral collar 15 is formed so as to extend along the rotational axis direction of the detergent stirring rotating body 14.

  A motor 16 for driving the detergent stirring rotator 14 is provided on the outside corresponding to the front side of the detergent dissolution chamber 13. The rotating shaft of the motor 16 and the detergent stirring rotating body 14 are connected via a connecting means (not shown). In the detergent dissolution chamber 13, a detergent discharge port 17 is provided at a site (the back side of the detergent dissolution chamber 13) where the dissolved detergent is transferred by the detergent stirring rotator 14.

  The motor 16 is supported by a motor support 18 and fixed with screws or the like. The rotating shaft of the motor 16 is rotatably supported by the bearing 30 held by the bearing holding portion 19. The bearing 30 is provided with a sealing member 31 on the side facing the detergent dissolution chamber 13. The dissolved detergent and water are prevented from flowing into the bearing 30.

  The detergent discharge hose 32 is connected to the detergent discharge port 17. The dissolved detergent dissolved in the detergent dissolution chamber 13 is sent to a drum washing tub (not shown) by the detergent pouring hose 32. Since the detergent pouring hose 32 has a bellows, it expands and contracts when the detergent dissolving device 3 is taken in and out.

  The detergent liquid is sent toward the detergent discharge port 17 by the spiral collar 15 by the rotation of the detergent stirring rotating body 14. The inner bottom surface of the detergent dissolution chamber 13 is inclined downward toward the detergent discharge port 17. The inclination angle θ is about 5 to 15 °. This inclination facilitates the detergent liquid to flow into the detergent discharge port 17. It is difficult for the detergent solution to remain in the detergent dissolution chamber 13.

  The upper body case 10 is provided with a detergent water inlet 33. The detergent water inlet 33 has a funnel or mortar shape, and has a bottom portion that communicates with the detergent dissolution chamber 13 via a passage. The bottom of the detergent water inlet 33 is provided with a net for receiving powder detergent.

  The overflow receiver 34 is provided so as to surround the detergent water inlet 33. The overflow receiver 34 is slightly higher than the upper edge of the detergent water inlet 33. It is also possible to cut out a part of the upper edge of the overflow receiver 34 or make a hole so that the overflow occurs.

  The overflow receiver 34 is communicated with the detergent discharge port 17 via the overflow drainage channel 35. The water overflowing from the detergent water inlet 33 is received by the overflow receiver 34 and poured into the detergent inlet hose 32 through the overflow drain 35 and the detergent outlet 17. For this reason, it is hard to occur that the storage part 4 of the washing machine main body 1 in which the detergent dissolution apparatus 3 fits gets wet with overflow.

  It is also possible to connect the overflow drainage channel 35 to the detergent dissolution chamber 13 to pour overflow water into the detergent dissolution chamber 13.

  The finishing agent charging part 36 and the bleaching agent charging part 37 are provided in the lower main body case 11 so as to be adjacent to the front side of the detergent water inlet 33 as shown in FIGS.

  The finish agent charging part 36 and the bleaching agent charging part 37 are partitioned by a partition wall 39 as shown in FIG. An detachable upper cover 50 is provided on the finishing agent charging part 36 and the bleaching agent charging part 37.

  The upper cover 50 is provided with a finishing agent inlet 51 and a bleaching agent inlet 52. Finishing agent inlet 51 and bleaching agent inlet 52 have the shape of a funnel or a mortar. The upper cover 50 is attached and detached by pulling out the detergent dissolving device 3 from the storage unit 4 of the washing machine body 1. Since the handle 53 is provided on the front side of the detergent dissolution apparatus 3 (the front side of the lower main body case 11), the detergent dissolution apparatus 3 can be easily put in and out.

  The ceiling of the storage unit 4 includes a detergent water supply port 54 that supplies tap water to the detergent water injection port 33. The detergent water supply port 54 communicates with the water supply electromagnetic valve A56 via the detergent dissolution water supply passage 55. At the tip of the water supply port 54, a spray plate 57 for spraying the discharge water discharged from the detergent water supply port 54 is provided.

Further, a finishing agent water supply port 58 for supplying tap water to the finishing agent input port 51 is provided on the ceiling of the storage unit 4.
Is provided. The finishing agent water supply port 58 is communicated with the water supply electromagnetic valve B 60 via the finishing agent water supply passage 59.

  Further, the ceiling of the storage unit 4 is provided with a bleaching water supply port (not shown) for supplying tap water to the bleaching port 52. The bleaching water supply port communicates with the water supply electromagnetic valve C70 through a water supply passage for bleaching water supply.

  As described above, the finishing agent charging unit 36 and the bleaching agent charging unit 37 are provided together in the detergent dissolving apparatus 3, and thus are more compact than those provided separately. Moreover, it becomes possible to form integrally.

  The operation flow of the washing machine will be described with reference to FIG.

  The operation of the washing machine starts (S step 501), and detergent guide sensing (S501) is performed.

  By the detergent standard sensing, the amount of detergent to be measured is put into the detergent dissolving apparatus 3, and the water A for dissolving the detergent (S step 503) is performed. In water supply A, it is reduced to about 5 L / min.

  The detergent stirring rotating body 14 is rotated by the motor 16 (S step 504), and after the elapse of T minutes (S step 505), the motor 16 is stopped (S step 506). With this level of stirring, the powder detergent is dissolved well and supplied to the washing tub of the washing machine.

  Water is supplied to the washing tub with water supply B (S step 507). Here, water supply of about 20 L / min is performed. When the water supply reaches the specified amount (S step 508), the water supply is stopped and the washing operation is started (S step 509). When the washing operation time has elapsed and washing is completed (S step 510), the process proceeds to draining (S step 511).

  When drainage is completed, dehydration is performed (S step 512), and rinse water is supplied after dehydration (S step 513). When the water supply reaches the specified amount (S step 514), the water supply is stopped and water supply is performed by the water supply C (S step 515) into which the finishing agent is poured.

  When the water supply C (S step 515) has been completed for T minutes (S step 516), the rinsing operation is started (S step 517). When the rinsing operation has elapsed for T minutes (S step 518), the process proceeds to the next step (S step 519). In this way, the washing operation is performed.

  The supply of detergents and finishes during the operation process will be described in more detail.

  A pre-weighed amount of powder detergent is put into the detergent water inlet 33 of the detergent dissolving apparatus 3 drawn out from the storage unit 4. At this time, a finishing agent and a bleaching agent are also charged from the finishing agent inlet 51 and the bleaching agent inlet 52. The liquid finishing agent or bleaching agent accumulates in the finishing agent charging unit 36 or the bleaching agent charging unit 37.

  Since the siphon mechanism 38 is provided in the finishing agent charging unit 36 and the bleaching agent charging unit 37, the liquid finishing agent and the bleaching agent remain in the finishing agent charging unit 36 and the bleaching agent charging unit 37.

  The detergent dissolving device 3 is set in the storage unit 4, the water supply electromagnetic valve A 56 is opened, and tap water is poured from the detergent water supply port 54 into the detergent water inlet 33. The water supply reduced to about 5 L / min is sprayed from the spray tray 57 to the powder detergent in the detergent water supply port 54. As the powder detergent is dissolved, it goes down into the detergent dissolution chamber 13.

  The dissolved powder detergent that has entered the detergent dissolution chamber 13 is well agitated by the spiral collar 15 of the rotating rotating body 14 that rotates here, and a high-concentration dissolved detergent liquid is generated. The generated dissolved detergent solution is transferred to the detergent discharge port 17 side by the spiral collar 15 and is sent from the detergent inlet hose 32 to the washing tub.

  In this way, by providing the stirring rotator 14 having the spiral collar 15 in the detergent dissolution chamber 13, the dissolved detergent liquid produced while being produced in the high-concentration dissolved detergent liquid can be transferred. The time spent on is reduced. Further, since a siphon mechanism for pouring is not required as in the prior art, the structure is simple and inexpensive.

  Since the inner bottom surface of the detergent dissolution chamber 13 is inclined toward the detergent discharge port 17, it is difficult for the dissolved detergent liquid to remain. After the transfer of the dissolved detergent solution, it is desirable to pour tap water into the detergent water supply port 54 to wash away the dissolved detergent solution adhering thereto. It is also desirable to clean the detergent stirring rotor 14 by pouring tap water while rotating the stirring rotor 14.

  Finishing agents and bleaching agents are performed during the washing operation. Since it has already remained in the finishing agent charging unit 36 and the bleaching agent charging unit 37, the tap water is supplied to the finishing agent charging unit 36 and the bleaching agent charging unit 37.

  That is, when the water level reaches the top of the siphon mechanism 38 due to the water supply to the finishing agent charging unit 36 and the bleaching agent charging unit 37, the water flows out by the siphon action. Once the outflow starts, it continues until the finishing agent input part 36 and the bleaching agent input part 37 are emptied. In this way, the finishing agent and the bleaching agent can be introduced at an arbitrary timing by selecting the timing of water supply.

  For this reason, since the detergent, the finishing agent, and the bleaching agent can be put into the detergent dissolving apparatus 3 at a time without shifting the timing, it is easy to use.

  After pouring a finishing agent or a bleaching agent into the washing tub, tap water is supplied to the finishing agent charging unit 36 or the bleaching agent charging unit 37 to wash the detergent dissolution chamber 13 in the same manner as the above-described detergent. desirable. By performing this washing, both the detergent dissolution chamber 13 and the stirring rotator 14 can be washed to the front side.
