  FIG. 12 is a plan view of the water surface portion of the washing machine of the present embodiment. FIG. 13: is a top view of the detergent melt | dissolution apparatus of the state which removed the storage case of the washing machine.

  As shown in FIGS. 12 and 13, a plurality of protrusions 30 a and 30 b are arranged on the inner side of the bottom surface of the flowing water surface portion 30 at positions facing the lower portions of the nozzles 31 i and 31 e of the water injection case 31, respectively.

Further, on the inner side of the bottom surface of the water flow surface portion 30, a concave ring configured in a shape in which a rib is protruded in a ring shape with a part cut away at a position facing the lower portion of the nozzle 31 h of the water injection case 31. Part 3
0c is disposed.

  The operation and action of the washing machine configured as described above will be described.

  The user opens the lid 26 and puts the laundry into the washing tub 15. Then, the storage case 32 of the detergent dissolving apparatus is pulled out from the opening, and a predetermined amount of detergent is put into the powder detergent storage portion 32a or the liquid detergent storage portion 32b. The opening is formed by the flowing water surface portion 30 and the water injection case 31. After a predetermined amount of softening agent is charged into the softening agent storage part 32c, the storage case 32 is stored in the opening.

  FIG. 14 is a plan view for explaining the positional relationship between the powder detergent stirrer and the water injection nozzle in the washing machine of the present embodiment, and shows a state in which the storage case 32 is stored. FIG. 15 is a plan view for explaining the positional relationship between the powder detergent agitator and the water injection nozzle in the washing machine, in which the plan view of (1) shows a state in which the housing case 32 has started to be housed, and FIG. The figure shows a state where the storage of the storage case 32 is completed, and shows a state where the storage case 32 is stored from the state of the plan view of (1) toward the state of the plan view of (6).

  When the storage case 32 is stored (see FIG. 15 (1)), the blades 35b of the powder detergent stirring body 35 come into contact with the nozzle 31d (see FIG. 15 (2)). As the storage case 32 is stored, the powder detergent stirrer 35 rotates by the contact of the nozzle 31d with the blade 35b of the powder detergent stirrer 35 (see FIGS. 15 (2) to (6)).

  By disposing the nozzle 31d in front of the powder detergent stirring body 35, when inserting the storage case 32, the blades 35b of the powder detergent stirring body 35 abut against the nozzle 31d and are stored while rotating. In the state in which the storage case 32 is stored, the powder detergent stirrer 35 is rotated at an angle substantially perpendicular to the water injection direction of the nozzle 31d, with one blade 35b on the back side of the blade 35b contacting the nozzle 31d. Further, since the distance between the nozzle 31d and the blade 35b is also uniquely determined, the powder detergent stirrer 35 rotates under the pressure of water and stirs the detergent and water even in a weak water supply amount under a low water pressure environment. Undissolved residue can be prevented.

  In a state where the storage of the storage case 32 is completed, the powder detergent stirring body 35 stops at a position where the blade 35b is substantially orthogonal to the discharge port of the nozzle 31d by rotation (see FIGS. 14 and 15 (6)). . Further, since the housing case 32 is positioned in the state where the housing case 32 is completely housed, the distance between the blade 35b of the powder detergent stirring body 35 and the discharge port of the nozzle 31d is also maintained constant.

  The powder detergent stirrer 35 stops at a position where the blade 35b is substantially orthogonal to the discharge port of the nozzle 31d, and the distance between the blade 35b and the discharge port of the nozzle 31d is also kept constant. Can be reliably rotated and started.

  When the housing case 32 is pulled out, the blades 35b of the powder detergent stirring body 35 abut on the nozzle 31d and rotate. The rotation of the powder detergent stirrer 35 eliminates adhesion due to foreign matter between the concave portion 35a and the convex portion 32e of the powder detergent stirrer 35. When the powder detergent stirrer 35 is not rotating well, the user can determine that an abnormality has occurred in the rotation of the powder detergent stirrer 35.

  The user operates a start switch provided on the operation display unit 28 to start the washing operation.

Thereby, the control apparatus 27 starts a washing process. The first water supply valve 34 a is opened for a predetermined time, and water flows into the first water flow path 31 a defined by the ribs of the water injection case 31. 5 and 8 show the water flow in broken lines. The water that has passed through the first water flow path 31a is poured into the powder detergent stirring body 35 from the nozzle 31d, and the powder detergent stirring body 35 rotates.

  The powder detergent stirring body 35 stops at a position where the blade 35b is substantially orthogonal to the discharge port of the nozzle 31d, and the distance between the blade 35b and the discharge port of the nozzle 31d is also kept constant. It starts receiving rotation efficiently.

  By the rotation of the powder detergent stirring body 35, the powder detergent is stirred with water in the powder detergent container 32a.

  Furthermore, the water that has passed through the first water flow path 31a is poured into the powder detergent container 32a from the nozzle 31e. The powder detergent and the mixed water are stored in the powder detergent container 32a, but part of the powder detergent flows out from the hole 32f to the water surface 30. When the amount of water supplied to the powder detergent container 32a exceeds the volume of the powder detergent container 32a, the water flows over the peripheral wall surface 32g and flows out to the mixed water container 32d.

  In the mixed water storage part 32d, the mixed water is bubbled by being poured from the nozzle 31f. Bubbles and mixed water in the mixed water storage portion 32d flow out from the hole 32h provided in the mixed water storage portion 32d to the flowing water surface portion 30. When the amount of water in the mixed water storage portion 32d exceeds the volume of the mixed water storage portion 32d, the water flows over the peripheral wall of the mixed water storage portion 32d and flows out to the flowing water surface portion 30. The foam and mixed water that have flowed out to the water surface part 30 are supplied to the washing tub 15 from the front end of the water surface part 30.

  The control device 27 opens the first water supply valve 34a for a predetermined time, and then opens the second water supply valve 34b for a predetermined time, and the second water supply compartment 31 is defined by the ribs of the water injection case 31. Water is caused to flow into the water channel 31b. 6 and 9 show the flow of water in broken lines. The water that has passed through the second water flow path 31b is poured from the nozzle 31g toward the liquid detergent agitator 36, and the liquid detergent agitator 36 rotates in a direction from the front to the rear of the housing case 32. The liquid detergent in the liquid detergent container 32b is dissolved by stirring and supplying water and air to the liquid detergent in the liquid detergent container 32b by the rotation of the liquid detergent agitator 36. Run water backwards. The water that has passed through the second water flow path 31b is poured into the liquid detergent container 32b from the nozzles 31h and 31i disposed before and after the cap 37.

  The mixed water poured into the liquid detergent container 32 b passes through the siphon channel 32 l and flows out from the container case 32 to the flowing water surface part 30. At this time, when the water injection into the storage case 32 is stopped, the liquid detergent water in which the liquid detergent remaining in the storage case 32 and water are mixed is sucked by the siphon effect of the siphon flow path 32l and almost all flows out. Thereby, the injected liquid detergent flows out without remaining.

  A part of the water flowing into the second water flow path 31b is poured into the powder detergent container 32a from the nozzles 31j and 31k and mixed with the powder detergent remaining in the powder detergent container 32a when the first water supply valve is opened. Then, it flows out from the hole 32f to the flowing water surface portion 30.

  Then, the foam, liquid detergent water, and mixed water that have flowed out from the storage case 32 to the water surface portion 30 are supplied to the washing tub 15 from the front end of the water surface portion 30.

  When the inside of the washing tub 15 has not reached the predetermined water level after the second water supply valve 34b has been opened for a predetermined time, the control device 27 performs the first water supply valve 34a and the second water supply valve 34a until the predetermined water level is reached. The operation of opening the water supply valve 34b for a certain time is repeated.

  When the inside of the washing tub 15 reaches a predetermined water level, the control device 27 closes the first water supply valve 34a and the second water supply valve 34b, stops water supply, drives the motor 20, and rotates the pulsator 18. The washing process is performed.

  When the washing process is finished, the control device 27 starts a rinsing process, drains dirty washing water, and performs intermediate dehydration.

  In the rinsing process, the third water supply valve 34 c is opened, and water flows into the third water flow path 31 c formed by the rib of the water injection case 31. 7 and 10 show the water flow in broken lines. The water that has passed through the third water flow path 31c is poured into the softener accommodating portion 32c from the nozzles 31l, 31m, 31n, 31o, 31p, 31q, and 31r. Then, it passes through the siphon channel 32 l and flows out from the housing case 32 to the flowing water surface portion 30.

  At this time, when the water injection into the storage case 32 is stopped, the softening agent water mixed with the softening agent remaining in the storage case 32 and the water is sucked by the siphon effect of the siphon channel 32l and almost all flows out. Thereby, the supplied soft detergent flows out without remaining.

  Then, the softener water that has flowed out of the storage case 32 to the water surface 30 is supplied to the washing tub 15 from the front end of the water surface 30.

  When the inside of the washing tub 15 reaches a predetermined water level, the control device 27 closes the third water supply valve 34c to stop water supply, drives the motor 20 to rotate the pulsator 18, and performs a rinsing process.

  In addition, when water is supplied in the washing process and the rinsing process, the nozzles 31d, 31e, 31f, 31g, 31h, 31i, 31j, 31k, 31l, 31m, 31n of the water injection case 31 are removed. After the water supplied from 31o, 31p, 31q, 31r hits the plurality of protrusions 30a, 30b and the concave ring portion 30c with a part cut away from the water surface portion 30, the washing tub 15 starts from the entire end of the water surface portion. To be supplied.

  Even when the housing case 32 is removed, the protrusions 30a and 30b and the concave ring portion 30c can prevent water from splashing from the water flow surface portion 30 and improve reliability.

  FIG. 16 is a process progress diagram in the embodiment of the present invention.

  In the first water supply in the washing process, the first water supply valve 34a and the second water supply valve 34b are alternately switched to introduce water to a predetermined water level (see FV1 in FIG. 16). This allows the user to dissolve the detergent using either a powder detergent or a liquid detergent. If the 1st water supply valve 34a and the 2nd water supply valve 34b are turned ON simultaneously, the flow volume of the water which flows through each will reduce, and since the pressure will become weak, the rotational force of a stirring body will weaken and detergent will remain easily.

  In the present embodiment, after the first water supply valve 34a is opened for 40 seconds, the second water supply valve 34b is opened for 40 seconds, and this is alternately repeated. The operation time of the first water supply valve 34a and the second water supply valve 34b is not limited to this operation time, so that the operation time of the siphon phenomenon exceeds the low water pressure region (0.01 Mpa) and the water level variation. A minimum water supply time can be set.

  In addition, after the main stirring in the washing step and the final rinsing step and before drainage, the second water supply valve 34b is turned on to introduce water into the second water flow path 31b (see FV2 in FIG. 16).

As a result, even when only the washing step or the rinsing step is used, it becomes possible to use the siphon to completely drain the liquid detergent. When the water has flowed first, the water accumulated in the water injection path may leak into the water injection case 31 due to a subsequent impact such as vibration and remain. By setting it as the water injection process of this Embodiment, it becomes possible to suppress the conventional problem.

  In the present embodiment, the water supply time of the washing process and the final rinse process is 10 seconds, but is not limited to this water supply time, and can be set as appropriate.

  As described above, in the detergent dissolution apparatus of the present embodiment, the storage case 32 is configured integrally with the storage portions 32a, 32b, and 32c into which the laundry auxiliary agent is charged. When the agent is charged, the laundry aid can be charged into each of the storage portions 32a, 32b, and 32c simply by opening the storage case 32, and convenience can be improved. In addition, a powder detergent stirrer 35 and a liquid detergent stirrer 36 for stirring and dissolving the detergent with water are disposed inside the powder detergent container 32a and the liquid detergent container 32b, and the water flow path 31a of the water injection case 31 is provided. 31b are provided with nozzles 31e, 31f, 31g, 31h, and 31i, so that it is possible to prevent generation of undissolved washing aid in the powder detergent container and improve the reliability of the washing machine.

  Further, in the detergent dissolving apparatus of the present embodiment, the nozzle 31d is disposed in front of the powder detergent agitator 35, so that the powder detergent is inserted when the storage case 32 is inserted into the storage case 32 after the washing aid is added. The blades 35b of the stirrer 35 abut against the nozzle 31d and are stored while rotating. In the powder detergent agitator 35, the back blade 35b adjacent to the blade 35b in contact with the nozzle 31d is rotated at an angle substantially perpendicular to the water injection direction of the nozzle 31d, and the distance from the nozzle 31d is also uniquely determined. Even in a weak water supply amount under a low water pressure environment, the powder detergent stirrer 35 rotates under the pressure of water and can prevent undissolved residue by stirring the detergent and water.

  Further, in the detergent dissolving apparatus of the embodiment, the liquid detergent agitator 36 is disposed in front of the housing case 32 while supporting the rotation shaft substantially horizontally, and is ahead of the rotation axis of the liquid detergent agitator 36. It is set as the structure which supplies water to the blade | wing. The liquid detergent stirrer 36 is rotated by water supply, agitates and supplies water and air to the liquid detergent, dissolves the liquid detergent, and generates foam. The cleaning liquid that has generated the foam is supplied to a cap 37 that causes a siphon phenomenon disposed behind the liquid detergent stirring body 36. Thereby, generation | occurrence | production of the undissolved residue in the storage case 32 of a liquid detergent can be prevented, the bubble overflow in the storage case 32 can be prevented, and the reliability of a washing machine can be improved.

  As described above, since the washing machine of the present invention has a housing case in which the housing portion into which the laundry assistant is put is integrally molded, when the user puts the laundry assistant, the user puts together in each housing portion. Can be accommodated and convenience can be improved. In addition, a stirring body that stirs the detergent with water and dissolves it inside the powder detergent container and the liquid detergent container, and a water injection nozzle in the water flow path of the water injection case, the undissolved residue in the washing aid container It is useful as a washing machine that can prevent the occurrence of bubble overflow in the storage case.
