The air supply pipe 26 for supplying the cleaning liquid is provided, but is not limited to this. For example, as shown in FIG. 10B, a cleaning liquid supply pipe 41 for supplying a cleaning liquid and an air supply pipe are provided. 10 and an air supply pipe 43 for supplying water, and a water supply pipe 43 for supplying a cleaning liquid and air (or water) as shown in FIG. Or one of the pipes 44. Even with such a configuration, substantially the same operation and effect as the above embodiment can be obtained.
[0045]
Further, as shown by the phantom line in FIG. 2, a piping and a delivery blower B for mixing air (or containing bubbles) with the cleaning liquid in the cleaning liquid tank 10 are provided, and air is mixed with the diluted cleaning liquid flowing through the bypass passage 17. A pipe for feeding (or containing bubbles) and a delivery blower B may be provided. Thereby, while having substantially the same operation and effect as the above-described embodiment, the cleaning liquid can be supplied to the foaming device in a state of being mixed (or containing bubbles) with air, and the cleaning liquid can be more efficiently used by the foaming device. It can be foamed to obtain a good foamed state.
