The water supply chamber 37 is a space located on the side of the container body 20 and facing the side wall 25 of the container body 20 accommodated in the apparatus body 30 and opened to the apparatus body 30.
As shown in FIG.
And a small-diameter water receiving section 52 that opens upward immediately below the large-diameter pipe section 51 and receives water injected from the large-diameter pipe section 51. The inner / outer diameter of the large-diameter tube portion 51 is 18/2.
The inside / outside diameter of the small-diameter water receiving portion 52 is 0 / mm and the inside / outside diameter is 12/14 mm, and both are coaxially arranged with a gap of about 5 mm in the horizontal direction. The upper part of the large-diameter pipe part 51 is the main body 30
It is connected to a small-diameter inlet 53 projecting upward from the top surface.

The small-diameter water receiving section 52 has a slit 54 opened in the axial direction. The slit 54 is a small-diameter water receiving section 52
The upper end to the lower end of the main body 30 are formed substantially vertically at the same width, the width is about 1 mm, and the concave portion 25a formed obliquely rearward of the apparatus main body 30, that is, in the opening 25 of the side wall 25 of the accommodated container main body 20. It is open toward. Water supply room 37
Is inclined inward of the apparatus main body 30 including the mounting base of the small-diameter water receiving section 52.

The operation of the detergent supply device 13 will be described below in a water saving mode in which a washing step is performed using bath water.
First, bath water is injected into the water supply chamber 37 from the inlet 53 connected to the bath water pump 14. The bath water is discharged from the opening of the large-diameter pipe section 51 and is received by the small-diameter water receiving section 52 disposed immediately below the large-diameter pipe section 51. Most of the water that has fallen into the water receiving section 52 rebounds into the large-diameter pipe section 51 and falls from the inner peripheral wall surface. For this reason, the splash of the bath water in the water supply chamber 37 can be suppressed.

The bath water received by the water receiving section 52 is quickly guided from the slit 54 to the discharge port section 36, so that the water splash in the water supply chamber 37 can be suppressed. For this reason, even when bath water is injected into the water supply chamber 37 in a state where the container main body 20 is not attached to the apparatus main body 30, the water splashed in the water supply chamber 37 rushes out of the front opening 35 through the outlet 36. Nothing. Since the slit 54 opens toward the concave portion 25a formed at the mouth of the side wall 25 of the accommodated container body 20, even when the water pressure of the bath water is high, the bath water is opened toward the concave portion 25a, Device body 3
0 can be guided to the mouth gap 38 along the bottom surface. Further, the bath water transmitted along the bottom surface of the apparatus main body 30 is formed on the side wall 25 of the container main body 20 by a triangular concave portion 25 for bath water outflow.
Since it can also flow out from b and be guided to the opening gap 38, it is possible to suppress the water splashing on the detergent stored in the detergent container 22. In addition, the slit 54 allows the device body 3
The detergent remaining at the rear of the bottom of the “0” can be washed away.
Furthermore, when detergent foam enters the water supply chamber 37, the foam flows along with the washing water from the water supply chamber 37 through the concave portion 25b to the drain port 36 below the containers 22, 23, so that the water is quickly drained to the inner tank 5. be able to.

Since the water supply chamber 37 is spaced from the finishing agent container 23 with the detergent container 22 interposed therebetween, the splash of bath water injected into the water supply chamber 37 may enter the detergent container 22. Does not reach the finish container 23. For this reason, it can prevent that a finishing agent mixes in the inner tank 5 with bath water in a washing process.

Bath water is supplied to the inner tank 5 from the outlet 36 through the water supply chamber 37, and is stored to a predetermined water level. next,
One of the solenoid valves provided at the water supply port for supplying tap water is opened and a predetermined amount of tap water is injected into the detergent container 22 from the inflow port 31 . The injected tap water is washed out of the stored detergent, passes through the outlet 36 together with the detergent, and is discharged to the inner tank 5.

When the detergent container 22 is filled with water, the container 2
In some cases, foaming of the detergent occurs in the inside 2, and the foam may flow out of the detergent container 22 into the water supply chamber 37. At this time, FIG.
As shown, the tap water supplied to the inflow port 31 is supplied to the water supply chamber 3.
Since water is sprinkled downward from the defoaming water spouting port 44 formed at the end of 7, the detergent foam that has entered the water supply chamber 37 is immediately erased.

Next, a washing step is performed using the bath water and the supplied detergent as washing water. After the washing process is completed and the electromagnetic valve 9 is operated to drain water from the flexible drain pipe 10, the electromagnetic valve is opened and a predetermined amount of tap water is injected from the inlet 31 into the detergent container 22. The injected tap water passes through the drain port 36 through the emptied detergent container 22 and passes through the inner tank 5.
And a predetermined rinsing step is started. When the rinsing process is started, the other solenoid valve provided at the tap water supply water supply port is opened, and a predetermined amount of tap water is injected into the finishing agent container 23. The injected tap water causes the stored finishing agent to overflow from the outlet 23a, pass through the outlet 36, and is discharged to the inner tank 5, and the finishing step is performed.

Since the finishing agent container 23 is arranged at a distance from the water supply chamber 37 with the detergent container 22 interposed therebetween, when the finishing agent is supplied, the splashed bath water is mixed or pushed out by the bath water to reduce the weight. Nothing.
