The powder detergent reservoir 42 has a powder detergent outlet 44 that is an opening at the rear, and the powder detergent charged into the powder detergent reservoir 42 is flushed with the supplied water and supplied from the powder detergent outlet 44. It flows out of the case 40. On the front side of the powder detergent storage portion 42, there is an inclined portion 421 that gradually decreases toward the rear. Here, what contains these powder detergents, liquid detergents, and softening agents which are surfactants is referred to as a laundry treatment agent. The powder detergent storage part 42, the liquid detergent storage part 46, and the softening agent storage part 50 are storage parts which can store the laundry processing agent containing surfactant.

  The liquid detergent reservoir 46 is provided with a liquid detergent outlet 48. The liquid detergent outlet 48 has a siphon structure, and includes a cap 48a, a cylinder 48b, and a lower hole 48c. Due to the siphon effect of the liquid detergent outlet portion 48, water accumulates up to the upper portion of the cap 48a, and then passes through the cylindrical portion 48b from between the cap 48a and the cylindrical portion 48b and flows out from the lower hole 48c. The liquid detergent thrown into the liquid detergent reservoir 46 flows along with the supplied water and flows out of the water supply case 40 from the liquid detergent outlet 48.

  The softener reservoir 50 is provided with a softener outlet 52. The softener outlet portion 52 has a siphon structure, and includes a cap 52a, a cylindrical portion 52b, and a lower hole 52c. Due to the siphon effect of the softener outlet 52, water accumulates up to the upper part of the cap 52a, and then flows out from the lower hole 52c through the cylindrical part 52b from between the cap 52a and the cylindrical part 52b.

The softening agent charged into the softening agent storage unit 50 flows along with the supplied water and flows out of the water supply case 40 from the softening agent outlet 52.

  As shown in FIGS. 7 to 10, a gap is formed between the water supply case 40 and the water injection case 36. More specifically, the rear end 402 of the powder detergent reservoir 42 of the water supply case 40, the rear end 403 of the liquid detergent reservoir 46, the rear end 404 of the softener reservoir 50, and the rear wall of the water injection case 36 A gap is formed between the lower surface 405 of the water supply case 40 and the lower surface 405 of the water detergent case 36 and the bottom surface 363 of the water supply case 36. The said gap | interval comprises the stirring chamber 60 for stirring powder detergent, liquid detergent, a bleaching agent, and a softening agent, and the supplied water. That is, the said gap | interval comprises the stirring chamber 60 of the laundry processing agent containing the powder detergent which is surfactant, a liquid detergent, and a softening agent. A water supply port 54 connected to the third water supply valve 333 is provided on the right side surface of the water injection case 36 so that water can be supplied to the stirring chamber 60. The water supplied from the third water supply valve 333 is directed in the left-right direction as shown by the arrow P in the figure, and the rear or bottom of the softener storage unit 50, the liquid detergent storage unit 46, and the powder detergent storage unit 42 The whole of the agitating chamber 60 is agitated by passing through the agitating chamber 60 and being reflected and inverted by the side wall of the water injection case 36. In the left-right direction, the third water supply valve 333 is defined as a direction in which the water supply case 40 is inserted or removed, that is, the front-rear direction in FIG. 7 is the first direction, and a direction substantially orthogonal to the first direction, ie, the left-right direction in FIG. The water supplied from is directed in the second direction.

Here, the third water supply valve 333 may be provided with a fine bubble generator 334 so that water containing fine bubbles can be supplied to the stirring chamber 60.
The fine bubble generator 334 can mainly generate bubbles including ultrafine bubbles having a bubble equivalent diameter of about 50 nm to 1 μm, for example. In general, fine bubbles are classified as follows according to the sphere equivalent diameter of the bubbles. For example, bubbles having a diameter of 1 mm or more are referred to as millibubbles, microbubbles having a size of about 1 μm to several hundred μm are referred to as microbubbles, and microbubbles having a diameter of less than 1 μm are referred to as ultrafine bubbles or nanobubbles. Further, fine bubbles of several hundred μm or less including micro bubbles and ultra fine bubbles are collectively referred to as fine bubbles.

  When the bubble diameter is less than 1 μm, the bubbles become smaller than the wavelength of light and cannot be visually recognized, and the liquid becomes transparent. These fine bubbles are known to have an excellent ability to clean an object in a liquid due to characteristics such as a large total interface area, a low flying speed, and a large internal pressure.

  For example, the ultra fine bubble has the following properties. That is, the ultra fine bubble stays in water for a long time while performing Brownian motion. Substances are decomposed by the energy generated by the crushing due to the self-pressurizing effect, and free radicals are generated. Since the bubble surface is negatively charged, the ultra fine bubbles repel each other and there is no bonding.

  Further, since the ultra fine bubble has a negative charge on the surface, it easily adsorbs a surfactant that is easily charged positively, that is, a detergent, a softening agent, and the like. For this reason, water containing ultra fine bubbles (hereinafter referred to as ultra fine bubble water, abbreviated as UFB water) can disperse detergents and softeners in water in a shorter time than ordinary tap water. For this reason, when UFB water is used, detergent dissolution and softening agent dissolution become good, and it is possible to reduce as much as possible that the powder detergent remaining undissolved without flowing into the water tank 20.

From such a property, when washing is performed using UFB water, a detergent and a softening agent can be used efficiently, so that a high cleaning effect and a high softening effect can be expected.
In addition, since microbubbles having a sphere-equivalent diameter of bubbles of about 1 μm to several hundred μm are negatively charged, water containing microbubbles (hereinafter referred to as microbubble water) is also compared to normal tap water. And has the effect of dispersing detergents and softeners in water in a short time. However, since microbubbles have a larger bubble equivalent diameter than ultrafine bubbles, they spend less time in water than ultrafine bubbles. For this reason, when UFB water is used, the time for which ultrafine bubbles stay in the water becomes longer, and the dispersion effect of the detergent and softening agent is further enhanced as compared with microbubble water.

  The water supplied from the third water supply valve 333 is supplied to the stirring chamber 60 at the rear of the water supply case 40. Here, water is supplied from the water supply device 32 from the upper part of the water supply case 40. The arrows in FIGS. 8, 9, and 10 indicate the flow of water supplied from the water supply device 32.

  As shown in FIG. 8, the powder detergent outlet 44 communicates with the stirring chamber 60, and when washing using the powder detergent, the powder detergent is pushed into the water in the powder detergent reservoir 42, and the powder detergent outlet It flows out of 44 and reaches the stirring chamber 60. Further, as shown in FIG. 9, the liquid detergent outlet 48 communicates with the stirring chamber 60, and at the time of washing using the liquid detergent, the liquid detergent is washed away by the water in the liquid detergent reservoir 46, and the liquid detergent. It flows out from the outlet 48 and reaches the stirring chamber 60. Further, as shown in FIG. 10, the softener outlet 52 communicates with the stirring chamber 60, and when rinsing, the softener is pushed away by the water in the softener reservoir 50 and flows out of the softener outlet 52. And reaches the stirring chamber 60.

  The powder detergent, liquid detergent, and softening agent that have reached the stirring chamber 60 are stirred by the water supplied from the third water supply valve 333 in the lateral direction, that is, the right direction, and are efficiently dispersed and dissolved. Moreover, when the UFB water by the fine bubble generator 334 is used as described above, the dispersion efficiency and dissolution efficiency of the powder detergent, the liquid detergent, and the softening agent are improved and can be dissolved more satisfactorily.

  The powder detergent, liquid detergent, and softener dispersed and dissolved in the water supplied from the third water supply valve 333 are the powder detergent reservoir 42, the liquid detergent reservoir 46, and the lower surface of the softener reservoir 50 and the water injection case. It flows forward through the gap with the water 36, flows out of the water injection case 36 through an outlet 361 provided at the lower front part of the water injection case 36, and is supplied into the water tank 20.

  FIG. 11 is a diagram showing a schematic configuration of the water supply device 32, and shows a cross-sectional view taken along the line BB of FIG. As shown in FIG. 11, the water supply device 32 is provided with water channels I1, I2, J, K1 to K5, and R, and a plurality of water injection holes 62 are provided in each water channel. The second water supply valve 332 is connected to the water channel K1. The water supplied to the water channel K1 is led to the water channels K2 to K5. Further, a priming pipe 35 (not shown in FIG. 11) is connected upward from the water channel K1, and the priming pipe 35 is connected to bath water intake means 34c (see FIG. 4). In the region V, the water channel J and the water channel K1 are three-dimensionally crossed, the water channel J passes through the upper side, and the water channel K1 passes through the lower side.

  A water supply valve unit 33 is connected to the water supply device 32 on the right side surface. The first water supply valve 331 of the water supply valve unit 33 is connected to the water channel J, and the second water supply valve 332 is connected to the water channel K1. The second water supply valve 332 is controlled so as to be in an open state during the washing operation to supply water, and the first water supply valve 331 is controlled to be in an open state during the rinsing operation to supply water. During the washing operation, water is supplied from the second water supply valve 332, and the supplied water is guided from the water channel K1 to the water channel K2, and reaches the supply region M to the liquid detergent storage unit 46. The supply region M exists at a position corresponding to the liquid detergent reservoir 46, and is specifically located above the liquid detergent reservoir 46.

  The water that has reached the supply region M falls from the water injection hole 62 to the liquid detergent reservoir 46. The liquid detergent is washed away by the water and flows out from the liquid detergent outlet 48 and reaches the stirring chamber 60. As described above, the liquid detergent that has reached the stirring chamber 60 is stirred by the water that is vigorously supplied from the water supply port 54 of the third water supply valve 333 that is directed in the lateral direction, that is, the right direction.

  The supplied water is guided from the water channel K2 to the water channel K3 and reaches the supply region L to the powder detergent reservoir 42. The supply region L exists at a position corresponding to the powder detergent reservoir 42, and is specifically located above the powder detergent reservoir 42.

  The water that has reached the supply region L falls from the water injection hole 62 to the powder detergent reservoir 42. In addition, a water injection hole 63 formed forward is formed in the water channel K3, and the water flowing out from the water injection hole 63 is supplied so as to hit the inclined portion 421 on the front side of the powder detergent reservoir 42, and the powder detergent. Is washed away by the water and flows out of the powder detergent outlet 44 and reaches the stirring chamber 60. As a result, the powder detergent in the powder detergent reservoir 42 easily flows from the front direction to the rear direction, and the detergent residue is reduced. The powder detergent that has reached the stirring chamber 60 is stirred by the water that is vigorously supplied from the third water supply valve 333 in the lateral direction, that is, the right direction.

  Furthermore, the supplied water is guided to the water channels K4 and K5. The water channel K5 is located behind the water channel K4, and the length of the water channel K5 is shorter than the length of the water channel K4. The water channel K5 located on the rear side is for pouring water corresponding to the rear side of the water injection case 36 and the water supply case 40 in which the detergent residue is likely to be generated, and thereby the detergent residue can be suppressed. The water channels K4 and K5 are located above the stirring chamber 60, and the water guided to the water channels K4 and K5 passes through the water injection hole 62 and falls into the stirring chamber 60. The water that has dropped into the stirring chamber 60 merges with the water supplied from the third water supply valve 333, that is, the water supply port 54, and promotes the flow from the water supply case 40 to the water tank 20.

  The water supplied from the first water supply valve 331 is guided to the water channel J, and passes through the region V of the three-dimensional intersection structure and reaches the supply region N to the softener storage unit 50. The supply area N is located above the softener reservoir 50, and water falls from the water injection hole 62 in the supply area N to the softener reservoir 50. The water that has fallen into the softener reservoir 50 pushes the softener and flows out of the softener outlet 52 into the stirring chamber 60. The softening agent that has reached the agitating chamber 60 is agitated by water that is vigorously supplied from the third water supply valve 333 in the lateral direction, that is, the right direction. The water supplied from the third water supply valve 333 does not pass through the powder detergent reservoir 42, the liquid detergent reservoir 46, and the softener reservoir 50, that is, the reservoir that can store the laundry treatment agent including the surfactant. Then, it is supplied to the stirring chamber 60.

  Furthermore, when the third water supply valve 333 includes the fine bubble generator 334, the powder detergent, the liquid detergent, and the softening agent are further dispersed and dissolved by the UFB water generated by the fine bubble generator 334. Is done. Thereby, since generation | occurrence | production of the melt | dissolution residue of a powder detergent, a liquid detergent, and a softening agent is suppressed, cleaning performance and a softness | flexibility performance can be exhibited and improved without waste.
