Abstract

A cleaning device including a disinfection water supply portion to supply cleaning water with a dissolved disinfection component, and a bubble generation portion to contain bubbles into the cleaning water on a downstream side of the disinfection water supply portion.

Claims (41)

1. A cleaning device comprising:

a disinfection water supplier that supplies cleaning water with a dissolved disinfection component;

a bubble generator to contain bubbles into the cleaning water on a downstream side of the disinfection water supplier, wherein an inlet of the bubble generator is communicatively connected to an outlet port of the disinfection water supplier;

a bypass channel to connect an upstream side of the disinfection water supplier with an upstream side of the bubble generator on a downstream side of the disinfection water supplier; and

a switching valve to selectively communicate a water supply source side with a disinfection supplier side or a bypass channel side, the switching valve being provided at an upstream side of the disinfection water supplier.

2. The cleaning device according to claim 1 ,

wherein the cleaning device comprises a gas dissolver that dissolves gas into the cleaning water on an upstream side of the disinfection water supplier, wherein the gas dissolver has an outlet communicatively connected to an inlet port of the disinfection water supplier.

3. The cleaning device according to claim 2 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

4. The cleaning device according to claim 2 ,

wherein the disinfection water supplier comprises an electrolytic cell to electrolyze cleaning water supplied from a water supply source side and to generate cleaning water containing a disinfection component, and the outlet port that flows out cleaning water from the electrolytic cell to a downstream side is positioned on an upper side of the inlet port that flows cleaning water into the electrolytic cell.

5. The cleaning device according to claim 4 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

6. The cleaning device according to claim 1 ,

wherein the disinfection water supplier comprises an electrolytic cell to electrolyze cleaning water supplied from a water supply source side and to generate cleaning water containing a disinfection component, and the outlet port that flows out cleaning water from the electrolytic cell to a downstream side is positioned on an upper side of an inlet port that flows cleaning water into the electrolytic cell.

7. The cleaning device according to claim 6 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

8. The cleaning device according to claim 1 ,

wherein the cleaning device comprises a gas dissolver that dissolves gas into the cleaning water on an upstream side of the disinfection water supplier, the gas dissolver having a gas-liquid mixing chamber to mix and stir pressurized cleaning water and gas, and

wherein the disinfection water supplier comprises an electrolytic cell to electrolyze cleaning water supplied from a water supply source side and to generate cleaning water containing a disinfection component, and the outlet port that flows out cleaning water from the electrolytic cell to a downstream side is positioned on an upstream side of an inlet port that flows cleaning water into the electrolytic cell.

9. The cleaning device according to claim 8 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

10. The cleaning device according to claim 1 ,

wherein the cleaning device comprises a gas discharger that discharges gas on an upstream side of the bubble generator.

11. The cleaning device according to claim 10 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

12. The cleaning device according to claim 1 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

13. A cleaning system comprising the cleaning device according to claim 1 ,

wherein a downstream side of the bubble generator is connected to at least one of a water supply channel to supply cleaning water to a toilet and a water discharge channel connected to a water discharger of the toilet.

14. A cleaning method for cleaning a cleaning target using the cleaning device according to claim 1 ,

wherein cleaning water is supplied to the cleaning target each time a predetermined fixed time elapses.

15. A cleaning method for cleaning a cleaning target using the cleaning device according to claim 1 ,

wherein for cleaning the cleaning target, cleaning water passed through the bubble generator by communicating the water supply source side with the bypass channel side is supplied to the cleaning target, then cleaning water passed through the disinfection water supplier and the bubble generator by communicating the water supply source side with the disinfection water supplier side is supplied to the cleaning target.

16. The cleaning device according to claim 1 ,

wherein the cleaning device comprises a gas dissolver that dissolves gas into the cleaning water on an upstream side of the disinfection water supplier, and

wherein the gas dissolver has a gas-liquid mixing chamber to mix and stir pressurized cleaning water and gas.

17. The cleaning device according to claim 16 ,

wherein on an upstream side of the disinfection water supplier, the cleaning device comprises a water storage to temporarily store cleaning water and a pump to send cleaning water stored in the water storage to a downstream side.

18. A cleaning method for cleaning a cleaning target using the cleaning device according to claim 16 ,

wherein for cleaning the cleaning target, cleaning water passed through the bubble generator by communicating the water supply source side with the bypass channel side is supplied to the cleaning target, then cleaning water passed through the disinfection water supplier and the bubble generator by communicating the water supply source side with the disinfection water supplier side is supplied to the cleaning target.
