In addition, the detergent dissolving device includes: a powder detergent stirring body arranged in the powder detergent containing part; a liquid detergent stirring body disposed in the liquid detergent storage part; a siphon flow path formed in the liquid detergent storage part and the softener storage part; a water flowing surface portion for holding the storage box to be freely taken out or put in; and a water injection box for injecting water into the storage box. In addition, the detergent dissolving device includes: a 1 st water flow path provided in the water injection box and used for injecting water into the powder detergent storage part; and a 1 st water supply valve communicating with the 1 st water flow path. In addition, the detergent dissolving device includes: a 2 nd water flow path provided in the water injection box for injecting water into the powder detergent storage part and the liquid detergent storage part; and a 2 nd water supply valve communicating with the 2 nd water flow path. In addition, the detergent dissolving device includes: a 3 rd water flow path which is provided in the water injection box and injects water to the softener storage part; and a 3 rd water supply valve communicating with the 3 rd water flow path. The detergent dissolving device further includes nozzles disposed in the 1 st, 2 nd and 3 rd water flow paths for supplying water to the powder detergent storage portion, the liquid detergent storage portion and the softener storage portion.
With this configuration, the detergent dissolving device places the softener container for introducing the washing aid into the storage case together with the powder detergent container and the liquid detergent container, so that the detergent dissolving device can introduce the washing aid into the respective containers at the same time when the user introduces the washing aid, and convenience can be improved. In addition, the powder detergent containing part and the liquid detergent containing part are provided with a stirring body for stirring the detergent and the water to dissolve the detergent, and the water flow path of the water injection box is provided with a nozzle, so that the dissolving residue of the washing auxiliary agent in the containing part can be prevented, and the reliability of the washing machine can be improved.
In addition, the liquid detergent agitator of the washing machine of the present invention has a horizontal rotation shaft, and a nozzle disposed in the 2 nd water flow path and supplying water to the liquid detergent storage part supplies water to the blades of the liquid detergent agitator.
With this configuration, since the softener storage section for inputting the softener is provided in the storage case together with the powder detergent storage section and the liquid detergent storage section, when the user inputs the washing aid, the softener can be inputted to each storage section at the same time, and convenience can be improved. In addition, the powder detergent storage part and the liquid detergent storage part are provided with stirring bodies for stirring the detergent and the water to dissolve the detergent, and the water injection nozzle is arranged on the water flow path of the water injection box, so that the dissolution and the residue of the washing auxiliary agent in the storage part can be prevented, and the reliability of the washing machine can be improved.
In addition, the water and the air can be stirred by the liquid detergent stirring body to be dissolved in the liquid detergent, and the cleaning liquid in which the foam is generated can be flowed downstream.
The powder detergent agitator of the washing machine according to the present invention includes a vertical rotating shaft and blades extending in a radial direction from the rotating shaft, and the nozzle for supplying water to the powder detergent storage portion supplies water to the blades of the powder detergent agitator.
With this configuration, since the storage case is provided for putting the powder detergent and the liquid detergent together with the washing aid such as a softener, the powder detergent, the liquid detergent, and the washing aid can be put together, and convenience can be improved. In addition, the detergent containing part is provided with a powder detergent stirring body for stirring the detergent and the water to dissolve the detergent, and the water flow path of the water injection box is provided with a nozzle, so that the dissolving residue of the washing auxiliary agent in the containing part can be prevented, and the reliability of the washing machine can be improved.
In addition, the washing machine of the present invention has a nozzle for supplying water to the blades of the powder detergent agitator, and the nozzle is positioned in front of the powder detergent agitator in the storage state of the storage case.
With this configuration, when the detergent is put into the storage box and then inserted into the storage box, the blade of the powder detergent stirring body hits the nozzle, the storage box is stored while rotating, the blade is guided at right angles to the water injection direction, and the distance between the blade and the nozzle is uniquely determined. Therefore, even in a low water supply amount under a low water pressure environment, the detergent agitator rotates in response to the pressure of water, and agitates the detergent and water to prevent residual dissolution.
Further, in the structure of the conventional detergent dissolving device, there is no member for suppressing the water potential of the supplied water when the water is supplied in a state where the storage case is removed, and therefore the supplied water collides with the water flow surface portion and bounces up, and there is a problem that the user and the floor where the washing machine is installed get wet.
The washing machine of the invention is provided with a plurality of projections formed opposite to the nozzle on the inner side of the bottom surface of the water flow surface part.
With this configuration, since the plurality of protrusions for suppressing the water potential of the water supplied to the flow surface portion are provided, even in a state where the storage case for the wash aid is removed, the water is prevented from bouncing off from the flow surface portion, and the reliability of the washing machine is improved.
In addition, the washing machine of the invention forms a concave ring part opposite to the nozzle on the inner side of the bottom surface of the water flow surface part.
With this configuration, since the recessed ring portion is provided for suppressing the water potential of the water supplied to the flow surface portion, even when the storage case for the detergent auxiliary agent is removed, the water is prevented from bouncing off from the flow surface portion, and the reliability of the washing machine is improved.
In the washing machine of the present invention, the recessed ring portion formed to face the nozzle is formed in a shape in which a rib is projected in a partially missing annular shape and an inner portion surrounded by the rib is recessed inside the bottom surface of the flow surface portion.
With this configuration, since the recessed ring portion is provided for suppressing the water potential of the water supplied to the flow surface portion, even when the storage case for the detergent auxiliary agent is removed, the water is prevented from bouncing off from the flow surface portion, and the reliability of the washing machine is improved.
The washing machine of the present invention includes a control means for controlling the 1 st water supply valve, the 2 nd water supply valve and the 3 rd water supply valve, and the control means alternately switches the 1 st water supply valve and the 2 nd water supply valve when water is supplied for the first time of the washing process.
With this configuration, the water injection device has the storage case in which the powder detergent storage part, the liquid detergent storage part, and the softener storage part for inputting the powder detergent, the liquid detergent, and the softener are integrally molded, so that the user can use the powder detergent and the liquid detergent, and convenience can be improved. In addition, since the stirring body for stirring the detergent and the water to dissolve the detergent is provided inside the powder detergent containing part and the liquid detergent containing part, the detergent can be prevented from remaining in the powder detergent containing part and the liquid detergent containing part, and the reliability of the washing machine can be improved.
The detergent can be dissolved regardless of which of the powder detergent and the liquid detergent is used, but when the 1 st water supply valve and the 2 nd water supply valve are simultaneously opened, the flow rate of the water flowing through the 1 st water flow path and the 2 nd water flow path is reduced, the pressure is reduced, the rotating force of the stirring body is reduced, and the detergent is liable to remain. However, the control means is configured to alternately switch the 1 st water supply valve and the 2 nd water supply valve during the first water supply in the cleaning step, so that the rotational force of the agitator in the powder detergent storage unit and the liquid detergent storage unit can be maintained, and thus the powder detergent and the liquid detergent can be made to flow smoothly.
In addition, the washing machine of the present invention opens the 2 nd water supply valve by the control means after the main agitation and before the water discharge in the washing process and after the main agitation and before the water discharge in the final rinsing process, and introduces the water into the 2 nd water injection part.
In a low water pressure area, the viscosity of the liquid detergent is usually higher than that of water, and therefore the liquid detergent may not be able to be made to flow out by switching 1 time, but with this configuration, a part of the liquid detergent having a relatively high concentration can be made to flow out first, and the liquid detergent can be made to flow out at once after increasing the dilution ratio. In addition, regarding the control of introducing water into the 2 nd water injection part by opening the 2 nd water supply valve after the main agitation and before the water discharge, the control can also make the liquid detergent flow when only the washing process or only the rinsing process is used.

In a state where the storage case 32 is stored in the storage space, the blades 35b of the powder detergent stirring body 35 located 1 piece farther than the blades 35b in contact with the nozzle 31d are positioned at an angle perpendicular to the water injection direction of the nozzle 31 d. Further, since the distance between the nozzle 31d and the blade 35b is uniquely determined, the powder detergent stirring body 35 is rotated by the pressure of water even in a low water supply amount under a low water pressure environment, and the detergent and the water are stirred, thereby preventing the dissolution residual.
When the storage of the storage case 32 is completed, the powder detergent agitator 35 rotates to stop one of the blades 35b at a position orthogonal to the discharge port of the nozzle 31d (see (6) in fig. 14 and 15). In addition, since the storage case 32 is positioned in the state where the storage of the storage case 32 is completed, the distance between the blade 35b of the powder detergent agitator 35 and the discharge port of the nozzle 31d is also maintained constant.
Since one of the blades 35b of the powder detergent stirring body 35 is stopped at a position 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 maintained constant, the powder detergent stirring body 35 can be reliably rotated and started.
When the storage case 32 is pulled out, the blade 35b of the powder detergent agitator 35 rotates in contact with the nozzle 31 d. By the rotation of the powder detergent stirring body 35, foreign matters between the concave portion 35a of the powder detergent stirring body 35 and the convex portion 32e of the powder detergent storage portion 32a are discharged, thereby preventing sticking caused by the foreign matters. When the powder detergent stirring body 35 does not rotate well, the user can determine that an abnormality has occurred in the rotation of the powder detergent stirring body 35.
Next, the user operates a start switch provided in the operation display unit 28 to start the washing operation.
Thereby, the control device 27 (see fig. 1) starts the cleaning process. The 1 st water supply valve 34a is opened for a predetermined time to allow water to flow into the 1 st water flow path 31a defined by the ribs of the water filling box 31. The flow of water is indicated by dashed lines in fig. 5 and 8. The water passing through the 1 st water flow path 31a is injected from the nozzle 31d toward the powdery detergent stirring body 35, and the powdery detergent stirring body 35 is rotated.
Since one of the blades 35b of the powder detergent stirring body 35 is stopped at a position 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 maintained constant, the powder detergent stirring body 35 efficiently receives the pressure of water from the nozzle 31d and starts rotating.
The powder detergent and water are agitated in the powder detergent storage part 32a by the rotation of the powder detergent agitator 35.
The water that has passed through the 1 st water channel 31a is injected from the nozzle 31e into the powder detergent storage section 32 a. The powder detergent and the mixed water are accumulated in the powder detergent storage part 32a, but a part of the mixed water flows out from the hole 32f (see fig. 4) to the flow surface part 30. When the amount of water supplied to the powder detergent storage part 32a exceeds the capacity of the powder detergent storage part 32a, the water flows out to the mixed water storage part 32d over the surrounding wall surface 32 g.
The mixed water is foamed in the mixed water storage section 32d by injecting water from the nozzle 31 f. The foam and the mixed water in the mixed water storage unit 32d flow out to the flow surface portion 30 through the holes 32h (see fig. 3 and 4) provided in the mixed water storage unit 32 d. When the amount of water in the mixed water storage unit 32d exceeds the capacity of the mixed water storage unit 32d, the water flows out to the flow surface unit 30 over the peripheral wall of the mixed water storage unit 32 d. The foam and the mixed water flowing out to the flow surface portion 30 are supplied to the washing tub 15 from the tip of the flow surface portion 30.
The controller 27 opens the 1 st water supply valve 34a for a predetermined period of time, and then opens the 2 nd water supply valve 34b for a predetermined period of time, thereby allowing water to flow into the 2 nd water flow path 31b defined by the ribs of the water filling box 31. The flow of water is indicated by dashed lines in fig. 6 and 9. The water passing through the 2 nd water flow path 31b is injected from the nozzle 31g toward the liquid detergent stirring member 36, and the liquid detergent stirring member 36 is rotated in a direction to move the detergent from the front to the rear of the storage case 32. The liquid detergent in the liquid detergent storage portion 32b is agitated by the rotation of the liquid detergent agitator 36 while supplying water and air to the liquid detergent in the liquid detergent storage portion 32b, thereby dissolving the liquid detergent and allowing the cleaning liquid with the foam generated to flow backward. The water passing through the 2 nd water flow path 31b is injected into the liquid detergent storage 32b from the nozzles 31h and 31i disposed in front and rear of the cap 37.
The mixed water poured into the liquid detergent storage 32b flows out from the storage case 32 to the flow surface portion 30 through the siphon flow path 32 l. At this time, when the water supply to storage case 32 is stopped, the liquid detergent water formed by mixing the liquid detergent remaining in storage case 32 with water is sucked by the siphon effect of siphon flow path 32l, and substantially all of the liquid detergent water is discharged. Thereby, the injected liquid detergent flows out without remaining.
Part of the water flowing into the 2 nd water flow path 31b is injected from the nozzles 31j and 31k into the powder detergent storage part 32a, and when the 1 st water supply valve 34a is opened, the water is mixed with the powder detergent remaining in the powder detergent storage part 32a and flows out from the hole 32f to the flow surface part 30.
Then, the foam, the liquid detergent water, and the mixed water flowing out from the storage case 32 toward the flow surface portion 30 are supplied to the washing tank 15 from the tip of the flow surface portion 30.
After the 2 nd water supply valve 34b is opened for a predetermined period of time, if the water level in the washing tub 15 is not higher than a predetermined level, the controller 27 repeats the operation of opening the 1 st water supply valve 34a and the 2 nd water supply valve 34b for a predetermined period of time until the water level reaches the predetermined level.
When the water level in the washing tub 15 reaches a predetermined level, the controller 27 closes the 1 st and 2 nd water supply valves 34a and 34b to stop the water supply, and drives the motor 20 to rotate the oscillator 18 to perform the washing process.
When the washing process is finished, the controller 27 starts the rinsing process, discharges the dirty washing water, and performs intermediate dewatering.
In the rinsing step, the 3 rd water supply valve 34c is opened to allow water to flow into the 3 rd water flow path 31c formed by the ribs of the water filling box 31. The flow of water is indicated by dashed lines in fig. 7 and 10. The water having passed through the 3 rd water channel 31c is injected from the nozzles 31l, 31m, 31n, 31o, 31p, 31q, and 31r into the softener storage section 32 c. Then, the water flows out from the storage case 32 to the water flow surface portion 30 through the siphon flow path 32 l.
At this time, when the water supply to storage case 32 is stopped, softener water formed by mixing the softener remaining in storage case 32 with water is sucked by the siphon effect of siphon flow path 32l, and almost all of the softener water is discharged. This allows the introduced softening agent to flow out without leaving any residue.
Subsequently, the softener water flowing out from the storage case 32 toward the flow surface portion 30 is supplied from the tip of the flow surface portion 30 to the washing tub 15.
When the inside of the washing tub 15 reaches a predetermined water level, the controller 27 closes the 3 rd water supply valve 34c to stop water supply, and drives the motor 20 to rotate the oscillator 18 to perform a rinsing process.
In addition, when water is supplied in the washing step, the rinsing step, and the like, in a state where the storage case 32 is removed, the water supplied from the nozzles 31d, 31e, 31f, 31g, 31h, 31i, 31j, 31k, 31l, 31m, 31n, 31o, 31p, 31q, and 31r of the water pouring box 31 hits the plurality of protrusions 30a and 30b and the partially missing recessed ring portion 30c of the flow surface portion 30, and then the water is supplied from the tip of the flow surface portion to the washing tub 15.
Even when the storage case 32 is removed, the projections 30a and 30b and the recessed ring portion 30c prevent the water from bouncing off the water surface portion 30, thereby improving reliability.
Fig. 16 is a process progression diagram of the washing machine according to the embodiment of the present invention.
When the first water supply in the washing step is performed, the 1 st water supply valve 34a and the 2 nd water supply valve 34b are alternately switched to introduce water to a predetermined water level (see FV1 in fig. 16). Thus, the detergent can be dissolved regardless of which of the powder detergent and the liquid detergent is used by the user. When the 1 st and 2 nd water supply valves 34a and 34b are simultaneously opened, the flow rate of water flowing through the 1 st and 2 nd water flow paths is reduced, and the pressure is weakened, so that the rotational force of the stirring body is weakened, and the detergent is likely to remain.
In the present embodiment, after the 1 st water supply valve 34a is opened for 40 seconds, the 2 nd water supply valve 34b is opened for 40 seconds, and this operation is alternately repeated. The present disclosure is not limited to this operation time, and the minimum water supply time can be set to a water amount exceeding the amount of water that will start the siphon phenomenon even in a low water pressure region (0.01Mpa) and in a case where there is a variation in the water level with respect to the operation time of the 1 st water supply valve 34a and the 2 nd water supply valve 34 b.
Further, after the main agitation and before the water discharge in the washing step and after the main agitation and before the water discharge in the final rinsing step, the 2 nd water supply valve 34b is opened to introduce water into the 2 nd water flow path 31b (see FV2 in fig. 16).
Thus, even when only the washing step or the rinsing step is used, the liquid detergent can be made to flow out by siphoning. When the liquid detergent is first flowed out, water accumulated in the water supply path may leak to the water supply cartridge 31 and remain due to subsequent shock such as vibration. By setting the water injection stroke of the present embodiment, the conventional problem can be suppressed.
In the present embodiment, the water supply time for introducing water into the 2 nd water flow path 31b before the water discharge in the washing step and the final rinsing step is set to 10 seconds, but the present disclosure is not limited to this water supply time and can be set as appropriate.
As described above, in the detergent dissolving device of the present embodiment, since the softening agent storage part 32c for inputting the softening agent is provided in the storage case 32 together with the powder detergent storage part 32a and the liquid detergent storage part 32b, when the user inputs the detergent and the softening agent, the softening agent can be input into the powder detergent storage part 32a, the liquid detergent storage part 32b, and the softening agent storage part 32c together, and convenience can be improved. Further, since the powder detergent agitator 35 and the liquid detergent agitator 36 for agitating the detergent with the water to dissolve the detergent are disposed inside the powder detergent storage 32a and the liquid detergent storage 32b, and the nozzles 31e, 31f, 31g, 31h, and 31i are disposed in the 1 st water channel 31a and the 2 nd water channel 31b of the water pouring box 31, it is possible to prevent the detergent and the softener from being dissolved and remaining in the powder detergent storage 32a, and to improve the reliability of the washing machine.
In the detergent dissolving device of the present embodiment, the nozzle 31d is disposed in front of the powder detergent stirring body 35. With this configuration, when the storage case 32 is inserted into the storage space after the detergent auxiliary agent is poured into the storage case 32, the blade 35b of the powder detergent stirring body 35 abuts against the nozzle 31d and rotates to store the storage case. The powder detergent stirring body 35 has 1 blade 35b located at the side and the back side of the blade 35b in contact with the nozzle 31d at an angle perpendicular to the water injection direction of the nozzle 31 d. Further, since the distance between the nozzle 31d and 1 of the blades 35b is uniquely determined, the powder detergent agitator 35 is rotated by receiving the pressure of water even at a low water supply amount in a low water pressure environment, and agitates the detergent and water to prevent the residual solvent.
In addition, the detergent dissolving device of the washing machine according to the present embodiment has the following configuration: the liquid detergent agitator 36 is disposed in front of the inside of the storage case 32 by horizontally supporting a shaft 36a which is a rotation shaft of the liquid detergent agitator 36, and supplies water to a blade 36b located in front of the shaft 36a of the liquid detergent agitator 36. The liquid detergent agitator 36 is rotated by supplying water, and water and air are agitated and supplied to the liquid detergent, thereby dissolving the liquid detergent and generating foam. The cleaning liquid with the generated bubbles is supplied to a cap 37 disposed at the rear of the liquid detergent stirring body 36 to generate a siphon phenomenon. This prevents the liquid detergent from dissolving and remaining in storage box 32, and also prevents the foam in storage box 32 from overflowing, thereby improving the reliability of the washing machine.
