Rotary spray device X is installed in bathroom 200 with guide case 10 facing toward bathtub 202 (bathtub) and washing area floor 203 (washing area) of bathroom 200.

[0115] As shown in Figures 31 to 33, the rotary spray device X is installed in bathroom 200 above bathtub 202 and the floor 203 of the washing area, with a gap between guide case 10 and bathtub 202, and a gap between guide case 10 and floor 203 of the washing area. The rotary spray device X is arranged at a gap between each nozzle body 8 (nozzle cylinder main body 74) and each side wall 204 (side panel) of bathroom 200. Each side wall 204 is arranged between ceiling 201 and bathtub 202, and between ceiling 201 and floor 203 (floor panel) of the washing area.

[0116] As shown in Figure 33, the rotary spray device X is arranged by removing the fixed plate 16 and plate fixing device 17 from the fixed cylindrical shaft 22 (medium diameter cylindrical portion 27), removing the liquid supply pipe 2 (liquid supply) from the fixed cylindrical shaft 22 (small diameter cylindrical portion 28), and penetrating the fixed cylindrical shaft 22 (small diameter cylindrical portion 28, medium diameter cylindrical portion 27) into the ceiling 201 (ceiling board) from inside the bathroom 200, with the step portion 30 sides of the small diameter cylindrical portion 28, medium diameter cylindrical portion 27 and large diameter cylindrical portion 26 protruding to the back side of the ceiling 201 (ceiling board) (the opposite side of the bathroom 200).

[0118] As shown in Figure 33, when the other cylindrical end side of the fixed cylindrical shaft 22 of the rotary spray device X protrudes to the back side of the ceiling 201, the fixed plate 16 is fitted onto the medium diameter cylindrical portion 27 (the other cylindrical end side of the fixed cylindrical shaft 22) from the back side of the ceiling 201, and the back surface 16B of the fixed plate 16 abuts against the ceiling 201 (ceiling plate) from the back side of the ceiling 201.

[0119] 33, when the plate back surface 16B of the fixed plate 16 abuts against the ceiling 201, the plate fixture 17 is fitted onto the medium diameter cylindrical portion 27 (the other cylindrical end side of the fixed cylindrical shaft 22) protruding from the back side of the ceiling 201, and is arranged in the small diameter cylindrical portion 26. In the rotary spraying device X, the male screw 31 of the medium diameter cylindrical portion 27 (the other cylindrical end side of the fixed cylindrical shaft 22) is screwed (inserted) into the female screw 63 of the plate fixture 17, and the plate fixture 17 is fitted onto the medium diameter cylindrical portion 27 (the other cylindrical end side of the fixed cylindrical shaft 22).

[0120] As shown in Figure 33, the rotary spray device X is fixed to the ceiling 201 by abutting the fixed plate 16 against the ceiling 201 from the back side of the ceiling 201 and abutting the other tube end 20B of the fixed cylinder part 20 against the ceiling 201 from inside the bathroom 201, rotating the plate fixing device 17 and pressing (abutting) one tube end 17A of the plate fixing device 17 against the plate surface 16A of the fixed plate 16, thereby clamping the ceiling 201 (ceiling board) between the fixed plate 16 and the fixed cylinder part 20 (the other tube end 20B).

[0121] In the rotary spray device X, when the fixed body 1 is fixed to the ceiling 201, the rotating body 3, each liquid discharge body 4-6, each mist liquid sprayer 7, each nozzle body 8, each mist liquid sprayer 9 and guide case 10 are positioned above (above) the bathtub 202 and the floor 203 of the washing area in the bathroom 220 and are supported so as to be freely rotatable relative to the fixed body 1 (ceiling 201).

[0122] 33, when the fixed body 1 is fixed to the ceiling 201, the rotary spraying device X arranges (fixes) the liquid supply pipe 2 (supply liquid) on the fixed body 1 (fixed cylindrical shaft 22) from the back side of the ceiling 201. In the rotary spraying device X, the liquid supply pipe 2 is fitted onto the small diameter cylindrical portion 28 (the other cylindrical end side of the fixed cylindrical shaft 22) protruding from the back side of the ceiling 201, and the liquid supply pipe 2 is connected (fixed) to the fixed cylindrical shaft 22 (small diameter cylindrical portion 29).

[0123] In the rotary spray device X, when the liquid supply pipe 2 is fixed to the small diameter cylindrical portion 28 (fixed cylindrical shaft 22), as shown in Figure 33, the liquid inlet passage α of the liquid supply pipe 2 is connected to the liquid introduction passage β of the rotary cylindrical shaft 40 through the small diameter cylindrical portion 29 (fixed cylindrical shaft 22).

[0124] 33, when the liquid supply pipe 2 is fixed to the small diameter cylindrical portion 28 (fixed cylindrical shaft 22), the other pipe end 2B of the liquid supply pipe 2 is connected to the liquid supply source Z on the back side of the ceiling 201. The liquid supply source Z causes the liquid (water) to flow into the liquid inflow path α of the liquid supply pipe 2 (water supply body).

[0125] In the rotary spray X, the liquid (water) that has flowed into the liquid inflow passage α flows through the liquid inflow passage α (inside the liquid supply pipe 2) and is discharged into the liquid introduction passage β (inside the rotating tubular shaft 40) of the rotating tubular shaft 40, as shown in Figure 33. The liquid (water) that has flowed from the liquid inflow passage α to the liquid introduction passage β flows through the liquid introduction passage β (inside the rotating tubular shaft 40) and flows from one tubular end 40A of the rotating tubular shaft 40 into the liquid flow passages γ of the liquid flow tubular portions 44 to 46, as shown in Figures 6, 11 and 33.

[0126] As shown in Figures 9, 29 and 33, the liquid (water) that flows into the liquid flow passage γ of each liquid flow cylindrical portion 44-46 flows through the liquid flow passage γ of each liquid flow cylindrical portion 44-46 (inside each liquid flow cylindrical portion 44-46) and flows out from one cylindrical end 46A side of each liquid flow cylindrical portion 44-46 (the side of each flow cylindrical closing portion 43) to the liquid conducting passage σ (in one outflow cylindrical closing portion 54) of each liquid outflow body 4-6 (liquid outflow cylindrical main body 12).

[0127] As shown in Figures 9, 29 and 33, the liquid (water) that flows into the liquid conducting passage σ of each liquid outflow body 4-6 flows through the liquid conducting passage σ of each liquid outflow body 4-6 (inside one of the outflow tube closure sections 54) and flows into the liquid outflow path τ (inside the liquid outflow tube main body 12) of each liquid outflow body 4-6 (liquid outflow tube main body 12).

[0128] The liquid (water) that flows into the liquid outflow path τ of each liquid outflow body 4-6 (liquid outflow tube main body 12) flows through the liquid outflow path τ (inside the liquid outflow tube section 53) of each liquid outflow body 4-6, as shown in Figures 9 and 33, and flows into each injection orifice 64 from the liquid outflow path τ side (the flat end surface 61A of each protrusion 61).

[0129] In each of the liquid outflow bodies 4 to 6, the liquid (water) that has flowed into each injection throttle hole 64 flows through the first and second injection flow paths λ1 and λ2 and is injected into each injection hole 64, as shown in FIGS.

[0130] In each of the liquid outflow bodies 4 to 6, the liquid flowing through the first and second injection flow paths λ1, λ2 flows in a spiral shape (helix) along the first and second injection spiral surfaces 71, 72 from the conical bottom plane 67B toward the conical top surface 67A of the injection guide core 67, and is injected into each injection hole 64. The first and second injection flow paths λ1, λ2 inject the liquid (water) flowing through the first and second injection flow paths λ1, λ2 into each injection hole 64, forming a vortex flow within each injection hole 64.

[0131] In each of the liquid outflow bodies 4 to 6, the gas (air) in the liquid (water) flowing through the first and second injection flow paths λ1, λ2, each injection orifice 64, and each injection hole 64 is pulverized (sheared) by the swirling flow (turbulent flow) to become a bubble liquid (bubble liquid containing air bubbles) in which a large number of fine bubbles and a large number of ultrafine bubbles are mixed and dissolved.

[0132] In each of the liquid outflow bodies 4 to 6, a large amount of fine bubbles and a large amount of ultrafine bubbles are mixed and dissolved in the bubble liquid (hereinafter referred to as bubble liquid (bubble water)) which is injected from each injection throttle hole 65 to each injection hole 64, and flows through each injection hole 64 toward the injection port 64A.

[0133] In each of the liquid outflow bodies 4 to 6, the bubble liquid (bubble water) flowing through each of the spray holes 64 is converted from the spray outlet 64A of each of the spray holes 64 into droplets containing a large number of fine bubbles and ultra-fine bubbles mixed therein, and these droplets are sprayed in the form of a mist from each of the spray holes 64. In each of the liquid outflow bodies 4 to 6, each of the spray holes 64 sprays from the spray outlet 64A a large number of droplets (water droplets) containing a large number of fine bubbles and ultra-fine bubbles mixed therein as a mist toward the bathtub 202 and the floor 203 of the washing area, and spreads throughout the bathroom 220.

[0134] The liquid (water) that flows into the liquid conducting passage σ of each liquid outflow body 4-6 flows through the liquid conducting passage σ of each liquid outflow body 4-6 (in one of the outflow tube closing sections 54) and flows into the liquid discharge passage ε of each liquid outflow body 4-6 (in the other outflow tube closing section 55).

[0135] 31 to 33, each mist liquid sprayer 7 sprays droplets containing a large amount of fine bubbles and ultra-fine bubbles mixed together from the nozzles 64A of each spray hole 64 toward the bathtub 202 and the floor 203 of the washing area in the bathroom 200, spraying the droplets containing a large amount of fine bubbles and ultra-fine bubbles mixed together onto the bathtub 202 and the floor 203 of the washing area. Each mist liquid sprayer 7 sprays the droplets containing a large amount of fine bubbles and ultra-fine bubbles mixed together from each spray hole 64 into the space between the bathtub 202 and the ceiling 201 (in the bathroom 200) and into the space between the floor 203 of the washing area and the ceiling 201 (in the bathroom 200).

[0136] In each nozzle body 8, the liquid (water) that has flowed into the liquid lead-out path ε (in the other outflow tube closing section 55) of each liquid effluent body 4-6 flows through the liquid lead-out path ε (in the other outflow tube closing section 55) and each liquid circulation hole ψ2, ψ4, as shown in Figure 29, and flows into the jet throttle hole 80 from the back surface 75B of the nozzle-cylinder closing section 75 (on the core support ring 83 side / inside the nozzle-cylinder section 76). The liquid guide shaft 88 guides the liquid W flowing through the liquid lead-out path ε of the liquid effluent bodies 4-6 to each liquid circulation hole ψ1-ψ4, and causes the liquid W to flow into each liquid circulation hole ψ1-ψ4.

[0137] In each nozzle body 8, the liquid (water) that flows into the ejection orifice 70 flows through the first and second ejection flow paths δ1, δ2, as shown in Figure 29, and is ejected into the ejection orifice 79 between the surface 75A of the nozzle cylinder closing portion 75 and the conical upper surface 82A of the ejection guide core 82 inserted into the ejection orifice 79.

[0138] In each nozzle body 8, the liquid flowing through the first and second ejection flow paths δ1, δ2 flows in a spiral (helical) shape along the first and second ejection spiral surfaces 90, 91 from the conical bottom plane 82B of the ejection guide core 82 toward the conical top surface 82A, as shown in Figure 29, forming a vortex flow within the ejection hole 79.

[0139] In each nozzle body 8, the gas (air) in the liquid (water) flowing through the first and second ejection flow paths δ1, δ2, the ejection throttle hole 80, and the ejection hole 79 is pulverized (sheared) by the swirling flow (turbulent flow) to become a bubble liquid (a bubble liquid containing air bubbles) in which a large number of fine bubbles and a large number of ultrafine bubbles are mixed and dissolved.

[0140] In each nozzle body 8, the bubble liquid (bubble water) flowing through the ejection holes 79 is converted into droplets (water droplets) containing a large number of fine bubbles and ultrafine bubbles mixed therein, and these droplets are sprayed in the form of a mist from the ejection holes 79. In each nozzle body 8, the ejection holes 79 spray a large number of droplets (water droplets) containing a large number of fine bubbles and ultrafine bubbles mixed therein, in the form of a mist.

[0141] As shown in Figures 31 to 33, each mist liquid sprayer 9 sprays a large amount of fine bubbles and ultra-fine bubbles mixed and dissolved (water droplets) from the spray holes 79 of each nozzle body 8 toward each side wall 204 of the bathroom 200, spraying a large amount of liquid droplets of fine bubbles and ultra-fine bubbles mixed and dissolved onto each side wall 204. Each mist liquid sprayer 9 sprays a large amount of fine bubbles and ultra-fine bubbles mixed and dissolved (water droplets) from the spray holes 79 of each nozzle body 8 into the space (inside the bathroom 200) between each side wall 204 and the rotary spray device X.

[0142] Each liquid outlet 4-6 is rotated (rotated in one direction) relative to the fixed body 1 together with the rotating body 3 [rotating cylindrical shaft 40 and rotating main body 41 (each liquid flow cylindrical section 44-46)], each mist liquid sprayer 7, each nozzle body 8, each mist liquid sprayer 9 and guide case 10 by spraying a large amount of liquid droplets containing a large amount of air bubbles from the spray outlet 64A of each spray hole 64.

[0143] Each mist liquid sprayer 7 sprays a large amount of liquid droplets (water droplets) containing air bubbles from the nozzle 64A of each spray hole 64 of each liquid outflow body 4 to 6 (liquid outflow tube main body 12), causing each liquid outflow body 4 to 6, the rotating body 3, each mist liquid sprayer 7, each nozzle body 8, each mist liquid sprayer 9 and the guide case 10 to rotate (rotate in one direction) relative to the fixed body 1.

[0144] As shown in Figures 31 to 33, the rotary spray device X sprays droplets (droplets containing air bubbles) containing a large amount of fine bubbles and ultra-fine bubbles mixed in or dissolved in the liquid flow bodies 4 to 6 (each mist liquid sprayer 7) from the nozzles 64A of the spray holes 64, and by rotating the rotor 3, each mist liquid sprayer 7, each nozzle body 8, each mist liquid sprayer 9 and guide case 10 relative to the fixed body 1 (rotating in one direction), the large amount of droplets (droplets containing air bubbles) containing a large amount of fine bubbles and ultra-fine bubbles mixed in or dissolved in the liquid flow bodies 4 to 6 (each mist liquid sprayer 7) can be sprayed and dispersed all around the circumference of the rotating cylindrical shaft 40 from the nozzles 64A of the spray holes 64 of the liquid flow bodies 4 to 6 (each mist liquid sprayer 7) and the spray holes 79 of the nozzle bodies 8 (each mist liquid sprayer 9). As a result, the rotary spray device X can sterilize (disinfect) and deodorize the air in the bathroom 200 by dispersing a large amount of fine bubbles and a large amount of ultra-fine bubbles mixed in and dissolving in the large amount of droplets within the bathroom 200. The rotary spray device X can spray a large amount of fine bubbles and a large amount of ultra-fine bubbles mixed in and dissolving in the large amount of droplets (droplets containing air bubbles) sprayed from the nozzles 64A of the spray holes 64 of the liquid outflow bodies 4 to 6 onto the bathtub 203 and the floor 203 of the washing area, and the sprayed fine bubbles and ultra-fine bubbles mixed in and dissolving in the droplets can clean dirt from the bathtub 202 and the floor 203 of the washing area, thereby sterilizing (disinfecting) and deodorizing the bathtub 202 and the floor 203 of the washing area.

[0145] As shown in Figures 31 to 33, the rotary spray device X rotates (in one direction) the rotor 3, the mist liquid sprayers 7, the nozzle bodies 8, the mist liquid sprayers 9 and the guide case 10 relative to the fixed body 1, so that a large number of droplets (droplets containing air bubbles) of a mixture of fine bubbles and a large number of ultra-fine bubbles ejected (sprayed) from the ejection holes 79 of each nozzle body 8 can be sprayed onto each side wall 204 all around the circumference of the rotating cylindrical shaft 40, and the sprayed fine bubbles and the large number of droplets of a mixture of ultra-fine bubbles can clean dirt from each side wall 204, making it possible to sterilize (disinfect) and deodorize each side wall 204.

[0146] The rotary spray device X may have a fixed body 1 fixed above the object to be cleaned (object to be cleaned), and the rotating body 3, each mist liquid sprayer 7, each nozzle body 8, each mist liquid sprayer 9 and guide case 10 may be arranged in the air (hanging in the air).
