The cover 6 is securely attached to the operation box 2 by a knob 16. On the other hand, the cover 6 can be easily removed from the operation box 2 by pushing the knob 16 back from the second opening 27 toward the first opening 26 to release the locked state of the knob 16.

Further, in this invention, the water wheel 7 is also configured to be easily removed from the compartment 3. Referring to FIG. 6, the water turbine 7 is connected to the partition wall 4
The bearing boss 31 is fitted onto a support shaft 30 attached to the bearing boss 31. In this case, the support shaft 30 has a neck portion 32 with a reduced diameter at its root portion,
On the other hand, the bearing boss 31 is provided with a slit 33 formed along its axial direction, and a protrusion 34 formed at the end of the boss so as to engage with the neck 32. Although only one slit 33 is shown in FIG. 6, two or more slits are actually provided, so that the end of the bearing boss 31 is elastically enlarged in diameter. It is configured to obtain. Therefore, this water turbine 7 has a slit 33 in the bearing boss 31.
The bearing boss 31 is removably attached to the support shaft 30 using the elastic deflection of the bearing boss 31.
When the projection 34 is inserted into the neck 3
2, it is firmly held against the support shaft 30. Moreover, this water turbine 7 is equipped with a holding means for holding the container 1 in a detachable manner. That is, referring also to FIG. 7, this water turbine 7 is
It consists of a substrate 36 including the bearing boss 31 described above, a flange 37 arranged concentrically with respect to the substrate 36 at a predetermined interval, and a plurality of blades 38 provided between these. , a selected number of blades, in this example 90
Four blades 3 arranged at intervals of degrees
8' is attached to the flange 37 in a cantilevered manner while being separated from the base plate 36, and each end thereof is provided with a stepped portion 39 projecting toward the center of the water turbine 7. ing. Furthermore, this water wheel 7
are integrally made of synthetic resin, and each blade 38' is somewhat elastically deformable. Reference numeral 40 is
This is a notch groove provided in the substrate 36 for cutting out the blade 38'. On the other hand, as shown in detail in FIG. 8, the container 1 includes a bottom plate 42 having a size to fit inside the water turbine 7, and a bottom plate 42 having the same diameter as the bottom plate 42 and concentrically spaced at a predetermined distance. The members 42, 43, 44 are made of synthetic resin in the mold. It is integrally constructed by injection molding. Note that reference numeral 45 is a reinforcing rib formed so as to hide the mesh portion of the mesh body 44.

Each blade 38' has a bottom plate 4 in contact with its step 39.
Although it is temporarily deformed outward by the second guard 46,
The collar 46 operates to elastically return to its original state once it has climbed over the stepped portion 39. In this way, container 1
is securely held from all sides within the water wheel 7 by the elastic restoring force of each blade 38'. By the way, when water is sprayed from the nozzle 9 onto the water wheel 7 and the container 1 and the detergent is dissolved while rotating them, a highly concentrated detergent solution remains between the bottom plate 42 of the container 1 and the base plate 36 of the water wheel 7. There is a risk that a glue-like sticky substance may accumulate in that area, and such sticky substance may cause an unpleasant feeling to the user when the container 1 is removed from the water wheel 7 and used as a measuring cup for detergent. This is not desirable as it means giving. Therefore, in this invention, when the container 1 is inserted and set in the water wheel 7 as described above, the bottom plate 42 of the container 1 and the base plate 36 of the water wheel 7 are
and the nozzle 9 between them.
Water is sprayed to prevent the above-mentioned sticky substances from adhering. In this embodiment, as shown in FIG. 2, the container 1 is formed shallower than the water wheel 7 to provide a predetermined gap between the bottom plate 42 and the base plate 36. spacer pin (not shown)
It is also possible to plant them so that a certain gap is always maintained.

As described above, according to this device, the nozzle 9
The detergent can be quickly dissolved by spraying water from the container 1 and rotating the container 1 together with the water wheel 7. However, at the flange 37 of the water wheel 7, the detergent solution and its foam are released from the opening 8 of the cover 6. It is configured so as not to leak to the operation panel 12 side. That is, in FIGS. 2 and 5, the flange 37 has a larger diameter than the opening 8, and is inclined so that the diameter gradually increases toward the rib wall 14 described above. This results in
The detergent solution and its bubbles that try to head toward the opening 8 from inside the compartment 3 are radially scattered by the flange 37 rotating together with the water wheel 7, and are scattered onto the rib wall 13.
After being sprayed on the wall 13, it is transmitted to the compartment 3.
It will be brought back inside. In this case, flange 3
Since a radial water film is formed between the rib wall 13 and the rib wall 13, there is almost no possibility that the detergent solution will leak through the space between them. Incidentally, as shown as a modification in FIG. 9, the tip of the flange 37 may be folded back in a dogleg shape, thereby making it possible to more effectively prevent leakage of the detergent solution.

As is clear from the above description of the embodiment, this invention consists of a compartment 3 formed in the operation box 2, a water wheel 7 rotatably mounted in the compartment 3, and a water supply source supplied from the water supply source. It includes a water injection nozzle 9 that sprays water toward the water wheel, and a porous detergent storage container 1 that is installed in the water wheel 7 through an opening 8 that opens toward the compartment 3. In an apparatus that rotates a container 1 together with a water wheel 7 by water, and agitates and dissolves the detergent in the container 1 while exposing it to water, the water wheel 7 has an inclined surface whose diameter gradually increases toward the opening 8, and , is characterized in that a flange 37 formed substantially larger than the opening 8 is provided. Therefore, compartment 3
The detergent solution and its bubbles are scattered radially by the flange 37 that rotates together with the water wheel 7, and there is little risk of leaking from the opening 8. On the other hand, the detergent solution and its bubbles flowing along the inner wall of the compartment 3 toward the opening 8 are blocked by the rib wall 14 formed around the opening 8, and are also radially sprayed at the flange 37. The detergent solution is returned to the compartment 3 through the rib wall 14.
